Description

"Device for moving a furniture part on a furniture"

The present invention relates to a device for guided movement of a furniture part on a furniture

according to the preamble of claim 1 and of

Preamble of claim 7.

State of the art:

Commercially available devices are known for opening

Furniture parts, z. B. as so-called touch-latch systems for guided movement of a furniture part of a piece of furniture. In this case, an energy store is loaded when closing the furniture part and opens this with the stored energy after its activation and / or the relevant furniture part. The energy storage device can be designed, for example, as an energy store.

Object and advantages of the invention:

Object of the present invention is a device for opening furniture parts according to the beginning

to improve the prior art.

The solution of this task takes place in a first

Embodiment starting from a device according to the

The preamble of claim 1 by the characterizing

CONFIRMATION COPY Feature. In an alternative embodiment, this object is achieved on the basis of a device according to the preamble of claim 7 by its characterizing feature. In the dependent claims are each advantageous and

expedient developments specified.

Accordingly, the present patent application concerns in the first approach, a device which in a mounted state on a furniture a force on a on the

Furniture part movably guided furniture part in which

Opening direction exerts. This includes an energy storage or a force storage device for moving the furniture part and a charging mechanism for the energy storage. The device is characterized in that first loading control means are provided which control the charging mechanism so that it loads the energy storage device in a movement of the furniture part in the opening direction.

This has the advantage that the energy applied to the regurgitation of the furniture part from a closed position to an open position of the device on the one hand immediately when opening the furniture part the energy storage for the next opening operation can be supplied as a precaution. Following this, the furniture part can be completely free in any permissible way

 Position to be moved. A "pushing" of the furniture part

 eliminated. On the other hand, by the usually at

 Opening a furniture part applied train movement this process also done very easy to handle, because, due to the pulling movement, the introduction of force comparatively

 uniform and usual way compared to a

 Push movement can be made easier felt. This can in particular less strong persons, such as. As children, the operation easier. But also in terms of

 relatively intense force requiring furniture movements such. As for heavy drawers or the like, such a power storage control a clear

 Bring comfort gain.

In a preferred embodiment, moreover, force Reduction means may be provided which cause a reduction in the force required in the charge of the energy storage device in comparison to an embodiment without force reduction means. For example, by an extension of the required for charging the energy storage extractor a corresponding reduction in the charge of the

Force accumulator required charging power can be realized.

In order to prevent that energy stored in the energy storage unintentionally escapes again, can continue in

Advantageously, energy storage-discharging means are provided, which are designed so that they discharge the

Prevent energy storage. Particularly advantageous they prevent this not only in the fully charged state, but already at the beginning of the first energy charge, so that, for example, even if an interruption of a started charging the previously stored energy is maintained.

For example, for a mechanical energy storage, for. As a memory spring, a relaxation movement preventing blocking system can be provided. After the interruption can then, for example, the remaining, still missing energy required for the next opening of the furniture part from the closed state, in the

 Energy storage are fed.

In a further preferred embodiment, it is also possible to provide second loading control means which control the charging mechanism so that it loads the force accumulator during a movement of the furniture part in the closing direction. This can for example be ensured that the energy storage at each

 Movement, whether to open or close the

 Furniture part, with the required opening for the next opening process energy is loaded.

Particularly advantageously, these second charging control means may be configured such that the charging mechanism also initiates the energy accumulator from a first charging control means initiated, but not completely finished Energy storage can continue charging. For example, this may be the case after an interruption of an opening process, or else directly by canceling such with, for example, immediate reversal of movement of the furniture part.

In a particularly preferred manner, it can be ensured in this case that the furniture part can not be closed until sufficient energy for its reopening in the

Energy storage is stored. One way to do this is to provide one for storage

Wiederaufstoßen the furniture part be required Mindestweges over which the furniture to be closed on the

Charging mechanism can act. This is particularly advantageous if the furniture part is to be closed immediately after regurgitation by the device according to the invention.

Another way to ensure that enough energy to reopen the furniture part is stored in the energy storage before it can be closed, by providing a closing in this case

 prevent locking mechanism. This can either be designed so that it engages a

 Locking mechanism prevents or already that

 Positioning two complementary locking elements

 prevents, for example, by blocking the

 Closing of the relevant furniture part. For both

 exemplary embodiments may e.g. B. in an advantageous manner by opening and closing the furniture part, the still missing energy can be stored in the energy storage. When blocking the closing of the

 the relevant furniture part, the blocking in particular by an opening movement of the furniture part into a

overcome at least almost completely open position, so then closing the furniture part is possible again. The power storage can be entered either by this additional opening movement and / or by the subsequent, renewed closing movement. Once the energy store is fully charged, For example, via a further mechanism that unlocks the locking locking mechanism and the furniture part are accordingly completely closed.

In a further preferred manner, furniture part enabling means can be provided which after complete charging of the

Force memory a freewheel mode for the furniture part

activate, so that the furniture part completely free in its

Opening or closing movement is.

In a further preferred manner, mode selection means may be provided which are designed in such a way that, when activated, they override the first charge control means. Under

activated state is understood in this case according to the invention that the user is given the opportunity to actively override the first charging control means. The loading of the energy storage then takes place only by means of a closing movement of the furniture part. In a preferred manner, a force reduction means for facilitating the

 Energy storage be provided in the energy storage.

According to a first solution alternative

 Embodiment, an apparatus for opening furniture parts movably guided on a furniture, with an energy storage device for moving the furniture part and a charging mechanism for the energy storage can be configured so that mode-selecting means for activating or deactivating Öffnungsweg- limiting means are provided for the furniture part.

In this way it can be determined whether the furniture part after opening by the device only up to a

 certain limited by limiting means opening path is opened out of its closed state,

 for example 5 to 10 cm. Or, if this, from

Restrictors unhindered, only depending on the ratio of the aufstoßenden and the furniture part in its natural movement restraining and damping forces, much further than in the first mode can be opened so that z. B. already without additional further opening an access to the This released storage space of the furniture part and / or the furniture or its contents is possible.

The formation of such a device for opening

Furniture parts is based on the knowledge that it is

different situation scenarios exist. For example, parameters that are perceived as significant may contain conflicting initial conditions, such as close or negative parameters

comparatively generous space, intentional or unwanted opening from the closed position of the

Furniture part, the presence or absence of the requirement without further action directly after the release of the

Opening mechanism on the front of the drawer and / or the furniture and / or goods stored therein have access z, such. B. access with dirty hands to a trash can, or the like.

Apart from the fact that from these parameters already several different situations for a single user can be felt as pre- or disadvantageous, the same situation for another user can be weighted differently by his personal needs.

For example, in a kitchen, a laboratory or other premises in which hands and / or gloves are contaminated by the preparation and / or preparation of materials, there may be a desire to place directly on a cutlery, kitchen utensil, tool or the like deposited in the closed furniture part to be able to access the same after its opening.

On the other hand, in the same basic situation, but in cramped conditions on the other hand, the desire to be prioritized to leave the furniture only open so far that, for example, with a limb, such. B. knee, foot, elbow, carpal or the like further opening of the relevant furniture part can be made possible. The same situation could be the case, for example, in the case of accidental opening of the relevant furniture part. Again, the desire for a short opening path over a long opening path outweigh. To meet these different situations and needs

To be able to take account of it, it is advantageous if the user or the user himself can determine by adjusting the mode-selecting means, how far the furniture part is opened by the device from its closed position.

Particularly preferably, this opening path limiting means may also comprise opening path adjusting means by means of which the opening path can be set in the limited opening mode, for example between 5 and 15 cm. It is also conceivable, however, in addition to or as an alternative to this, another opening path limiting means, by an opening path different from the first opening path limiting means

 (bigger or smaller).

In one possible embodiment, the opening path limiting means may comprise a stop, for example an elastically deformable element, such as a

Rubber buffer and / or a stop spring made of plastic or metal and / or a damping element and / or the like. Particularly preferably, the stop can the

Charging mechanism for the energy storage include, for. B. with or without stopper and / or damping means.

The charging mechanism may in this case form, for example, a first opening path limiting means, which is at

 Activation, for example, an opening way of about 10 cm. If another, larger or smaller

 Opening path is desired, in a first

 Embodiment be provided a repositioning of the attachment point. For example, by axial adjustment of an associated with the supercharging mechanism and / or formed on this stop and / or spacer of the supercharging mechanism itself and / or an activation or

Deactivation of such a spacer and / or another and / or the like more. It is also conceivable, however, a change in position of the supercharging mechanism itself. Particularly preferred here is an adjustment of the ejection path both in terms of an enlargement and a reduction.

In order to be able to open the furniture part from its closed position, power storage release means may be further provided. Particularly preferably, this may be a mechanism that, for. B. by a in

Closing direction of the furniture part briefly initiated pressure initiated, stored in the energy storage energy

release and the furniture part can belch to how

described above, an access to the furniture and / or

To allow furniture part or its contents.

In a further preferred embodiment, a collection device for the furniture part can also be provided below. Particularly advantageous, this may have a damping element, which is a gentle closing of the furniture part

enable .

Also, additional or alternative damping means may be advantageous, especially if the furniture part in question, for example, a heavily loaded drawer, but also quite a furniture door, which are pushed with great momentum. If the energy storage, z. B. already before, is fully charged, and therefore can no longer absorb energy, or the momentum to close the

 Furniture part is so big that only part of his

 Close energy is required to fully charge the energy storage, the damping element can this

 make excess kinetic energy harmless during the closing process.

A third aspect of the present invention relates to a piece of furniture with a movably guided furniture part. This piece of furniture is characterized in that it comprises a device for opening furniture parts that are movably guided on a piece of furniture in accordance with the previously described embodiments. Exemplary embodiment:

The present invention will be described in more detail below with reference to the accompanying drawings.

In the figures 1 to 17 are below, purely by way of example and schematically, possible embodiments of

Device according to the invention described. FIG. 1 shows a device 1 for opening a furniture part 2 movably guided on a furniture 3, in this case in the form of a cabinet door in its closed state of rest. The furniture part can also be a drawer or another kind or designated, movable on a piece of furniture

be arranged element. The opening of the furniture part takes place after an initiating, a locking mechanism 12 unlocking pressing the hinge-distal part of the door by means of the thus released, stored in a spring-like power storage 4 energy.

For charging the energy storage spring 4, a first, the positions 7.1 and 7.2 comprehensive charging mechanism 7 is provided. The position 7.1 in this case comprises a, in a pivot point 7.1.2 pivotally mounted lever 7.1.1.

This is at a first end 7.1.3 via a hook-shaped power storage spring receiving the force to open the movable furniture part in its released state

providing spiral spring 4 connected. A, based on the pivot point 7.1.2 of the spring receptacle 7.1.3, opposite second end 7.1.4 of the lever 7.1 is the openable

 Door element 2 assigned. One about it

 Bearing point 7.1.5 rotatable roller 7.1.6 allows both very low-friction and low-noise contact when the lever 7.1.1 moves along the furniture part 2 to be opened.

A force reduction means 9 is exemplified here in the form of a relative to the basic element of the lever 7.1.1

 and / or its pivot point 7.1.2 formed according to the two directions of the arrow 7.1.3.2 displaceably mounted lever sub-element. For varying the force application point of

Energy storage spring receptacle 7.1.3 is to the relevant Lever end a longitudinal slot 7.1.3.1 provided.

Another possibility of influencing the distance in the

closed resting state between furniture and it

movably guided, to be opened by the device

Furniture part and / or to adapt the device 1 to a correspondingly predetermined distance can by a

Positioning means 18, here for example in the form of an eccentric screw 18 may be provided. By means of such a positioning means, the release position for the activation of the opening door element 2 can be adjusted to the required width of the "empty slot" between furniture and door.

By means of the positioning means 18 can be a positioning of the furniture part-release means 12 relative to the furniture 3 and / or against a part of the device 1 receiving

Realized base plate 1.1 and thus their trigger point according to the directions of the two arrows 18.1 and 12.1.1 be varied. In contrast to an eccentric design, the positioning means 18 can also be realized, for example, in the form of a slot which can be displaced with respect to a fixing point or another corresponding embodiment.

In the embodiment shown here, the locking means 12 or furniture part release means 12 comprise two pivoting levers 12.1 and 12.3 pivotably mounted via a respective pivot point 12.1.2 or 12.3.2 and coupled to a connecting lever 12.2. The first pivot lever 12.1 has two aligned approximately in the same direction and connected to a two knee sections having intermediate piece, approximately rectilinear lever ends. The tip of the first lever end 12.1.3 is associated with the door element 2 to be opened and pivots the pivot lever 12.1 on the pivot point 12.1.2 and parallelogram over the

Connecting lever 12.2 driven second pivot lever 12.3. In this case, the hook-shaped end 12.3.1 is disengaged from its associated complementary, here exemplarily pin-shaped locking element 12.4. The device 1 for opening the movably guided furniture furniture part is thereby unlocked. You can the example here to open door 2 after completion of the

Triggering the locking mechanism 12 and acted on the actuation of the furniture part-release means 12

Force action according to the arrow 2.1 open.

To return the parallelogram pivotable

Lever mechanism can be a return means 12.5, here

exemplified as a helical tension spring,

be provided. Damping elements 12.1.4, 12.3.3 and 12.4.2 can to further increase the ease of use for the two levers 12.1 and 12.3 and the locking pin 12.4

be provided. As materials of the damping elements z. B. elastic sheaths of the relevant

 Stop elements find use, such. As O-rings, rubber or plastic buffer or the like.

The position 7.2 of the illustrated in Figure 1

Charging mechanism 7 for the energy storage 4 is here

exemplified realized in the form of a hinge 7.2. It comprises a furniture part adapter 7.2.1, a connecting piece 7.2.3 movably coupled thereto via a bearing 7.2.2, a tensioning lever 7.2.5 coupled thereto via another bearing 7.2.4 and an adjoining one, in a bearing 7.2.7

 pivotally mounted control cam 7.2.6 with a

 Edge 7.2.6.1. The flank of the control cam moves when opening the furniture part to be opened by the device 1 in the direction of the arrow 7.2.6.1.1.

A for the sake of completeness still described with reference to Figure 1, the third end 7.1.10 of the pivot lever 7.1 forms the complementary control to the position 7.2 of the device 1 and both together, together with the first end of the 7.1.3 pivotable about the pivot axis 7.1.2

Pivoting lever 7.1.1 a first charging mechanism 7 for the energy storage 4. This charging mechanism is effective when the furniture part 2 regularly from its slightly open position after unlocking the release mechanism 12th or the activation of the furniture part enabling means 12 resulting opening position is opened further. For this purpose, the third end pivots 7.1.10 of the unlocked

Swivel lever 7.1 according to the arrow 7.1.10.1 to the

Pivot point 7.1.2 until the blocking of the pivoting movement against the control cam 7.2.6. Preferably, the

Geometries of the individual sub-elements of the device 1 be designed so that the force accumulator 4 in this position still has a slight bias. Thus, all the elements of the device 1 involved can be stabilized in their respective working position.

By means of a bearing in a bearing point 7.1.12

Rolle 7.1.11 a virtually frictionless control flow and thus improved management of the movement of the third end 7.1.10 of the pivot arm 7.1 upon application of a corresponding force by the control cam 7.2.6 can be achieved.

Upon further opening of the furniture part 2 as shown in Figure 2, in the direction of arrow 5, the opening gap increases by the distance 2.2. By thus controlled over the hinge-like part 7.2 cam movement in

 Direction of the arrow 7.2.6.1.1 moves the roller 7.1.11 along the running at the edge 7.2.6.1 cam in the direction of the arrow 7.1.10.1. As a result, the pivot lever with its second end 7.1.4 according to the arrow 7.1.4.1 in

 Directed closing state of the device 1 moves. In the

 Representation of Figure 2 results from this example, a reduction of Ausschwenkabstandes by the amount 7.1.4.2. By pivoting the pivot arm 7.1 also pivots its first end 7.1.3 against the tensile force of

 Force memory 4 and loads it to prepare for the next opening process for the furniture part so long until the

 Locking hook 12.3.1 after a Ausschwenkvorgang by pressing the locking bolt 12.4.1 against its

the front side of the guide flank returns to its original locking position with the locking bolt 12.4.1. The locking elements 12.3.1 and 12.4 realize in this embodiment thus a force storage unloading lock means 10. This can be opened

Furniture part 2 are moved completely freely from this pivoting position. Both in the further opening direction as well as in the closing direction, to the regular scheduled

Closed state with the above-described

"Front gap" 12.1.1 between furniture 3 and furniture part 2. The control cam 7.2.6 can be here with the extension of the edge 7.2.6.1 on the role of 7.1.10, touching or without contact, in her from the pivot point 7.2.7 predetermined

Move movement curve along.

After fixation of the thus re-charged energy accumulator 4 by the energy storage-unloading locking means 10, here in the form of the hook-shaped locking 12.3.1 and 12.4, that is

Device tripping end 12.1.3 of the pivoting lever 12.1 again in its rest position and thus ready for the triggering of the next opening operation by pressing the furniture part 2 ready. Subsequently, a movement of the

Furniture part 2, without influencing the energy stored in the energy storage 4 possible.

In a second embodiment, a charging mechanism may be designed so that the furniture part by closing in the direction of arrow 6 again loads the energy storage for the next opening operation. And without having to open the furniture part for this more than by a

 unintentional triggering of the device-based

 Opening operation of the furniture part 2 from the

 Closed position is the case. This includes the

 Charging mechanism 7, the pivot lever 7.1 with its two ends 7.1.3 and 7.1.4, and in a particularly advantageous manner, the other elements already described.

Furthermore, this example has been described here

Embodiment of a so-called. Safety or emergency charging mechanism 7.3. This includes charging control means 8 in the form of an elongated extension 7.3.1 and a further pivoting element, in particular in the form of a pivoting or tilting lever 7.3.3.

The elongated extension 7.3.1 is shown in the

Embodiment in the direction of the longitudinal extension of the

Swivel lever 7.1.1 aligned aligned and preferably out. At a first end 7.3.1.1 it is fixed by means of a fixing 7.3.2. The fixation can

for example, by clamping or other appropriate fixing method, z. B. by means of a pin 7.3.2. The opposite end 7.3.1.2 forms a thrust bearing for the one end 7.3.3.1 of the as a pan or rocker arm

formed second charge control means 8. This

Thrust bearing 7.3.1.2 may, for example, in the form of a

Clamping bolt be realized, which is arranged on the end, for example, designed as a spring element 7.3.1 first charging control means 8.

The pivot lever 7.1.1 can be swiveled around the fixing pin 7.3.2 in accordance with the path length of the slot-shaped recess 7.3.5, wherein the fixed by the pin, elastic, elongated extension 7.3.1 in the

 Fixing pin 7.3.2 associated end position stable remains. Without applying force to the rocker arm 7.3.3 therefore pushes the clamping bolt 7.3.1.2 due to the relative movement of the pivot lever 7.1.1 on the lever end 7.3.3.1 of the rocker arm over and provides an abutment for receiving the through

 Closing movement of the door 2 exerted force.

Starting from the illustration in Figure 1, in which the device 1 in the locked state and the elongated

 Extension 7.3.1 are shown in the closed rest position, pushes when opening the furniture part 2 of the clamping bolt by a relative movement between the swing arm 7.1.1 and the elongated extension 7.3.1 at the end 7.3.3.1 of the swivel or folding lever 7.3.3 over ( see Figure 2). As a result, the second end 7.3.3.2 pivots out of the outer alignment of the

Swing lever 7.1.1 out and serves as an abutment for that too opening furniture part 2. Thus, a distance between the roller 7.1.6 and the inner contact surface of the furniture part 2 is generated. When closing the furniture part 2 in the direction of

Arrows 6 clamps the furniture part on the swivel or

Rocker arm 7.3.3 the clamping bolt 7.3.1.2, so that a total of a stable support for the furniture part 2 results.

This support causes the transmission of the on the

Furniture part 2 when closing impressed force on the

Lever mechanism of the pivot lever 7.1.1 into the

Energy storage spring receptacle 7.1.3 and thus allows the charging of the energy accumulator 4 when closing the furniture part, without having to open this.

The distance generated by clamping the pivoting or rocker arm 7.3.3 prevents activation of the furniture part unlocking means 12 in the manner of unlocking the

Locking device 12, as they would otherwise be done by pressure on the pivot lever end 12.1.3.

After engagement of the locking mechanism 12, the energy stored in the energy accumulator 4 is stored in a secured manner. The furniture part 2 can from the closing movement

 required force application are exempted, thus no longer loaded with force from the outside door can the required for the clamping of the clamping bolt 7.3.1.2

 No longer apply clamping pressure and during this

 Closing movement in its length stretched, spring-like, elongated extension 7.3.1 can reduce the traction built up in it by contracting. The clamping bolt 7.3.1.2 is thereby withdrawn together with the spring element 7.3.1 in its original starting position and the Schwenkbzw. Rocker lever 7.3.3 released. Subsequently, the entire device is again in the starting position according to the

 Representation in FIG. 1.

A further possible embodiment of a device for opening a furniture part movably guided on a furniture is described below with reference to FIGS. 3 to 6 described, in which case the furniture part is preferably designed as a sliding furniture part, in particular as a drawer or the like.

Accordingly, the example illustrated here includes

movable guide and / or fixation of the furniture part 2 provided on the furniture 3 movement and / or guide units 20, here the pull-out rails, separate assemblies may be formed.

The individual elements of the 7.4 assigned

Charging mechanism 7 can hereby on a

 Basic support 7.4.10 be arranged, in turn, operated in a further advantageous manner with at least with respect to the assembly of this assembly without tools

 Fixing 7.4.10.1, as shown here by way of example, be attached to the furniture 3, preferably at corresponding

 complementary receiving elements 20.1, these being particularly advantageous on carcass rails of the guide units 20th

 are arranged or provided. The elements of item 7.4 can, in a particularly preferred manner as a separate

 trained assembly can be realized. This can be advantageous both in terms of a modular design of the device 1 and in terms of a retrofit option for appropriately provided furniture and furniture parts.

A corresponding structure and a corresponding fixation can for the complementary elements 7.5 of

 Charging mechanism 7 may be provided. Again, you can

For example, a base support 7.5.10 in correspondence to the basic support 7.4.10 for positioning and fixation of it arranged components with the movably guided

Furniture part 2, in particular advantageous for this purpose

provided extract rail of the guide unit 20 may be connected. These components of the device 1 can be advantageously designed as a separate assembly.

By providing a latching system, a simple position adaptation for optionally different elements of the position 7.5 and / or possibly different pieces of furniture can be made possible in an advantageous manner.

Another adjustment with respect to the position of the example here as a clamping wedge 7.5.3 trained charge control means 8 can by a designated, variable fixation along its longitudinal extent on the

Basic carrier 7.5.10 can be realized. Particularly advantageous, this variable fixation also a locking system

 by means of which the clamping wedge of a

 corresponding longitudinal position can be connected to the base plate, in particular advantageously with a tool-less operable at least during assembly fixing, z. B. in the form of a resilient locking lug or the like.

To compensate for dimensional tolerances and / or to reduce the influence of lateral forces occurring in further

 Advantageously, a floating storage of

 Spannkeiles 7.5.3 be provided. That is, it may be provided a game-prone side fixation.

Similar to the position 7.1 described for opening a door, the position 7.4 comprises an angled pivoting lever 7.4.1 mounted in a pivot point 7.4.2. Also, this pivot lever 7.4.1 has a first, connected to the trained in the form of a tension spring 4 energy storage end 7.4.3 and on the bearing point 7.4.2 opposite second, with released lock the drawer 2 expelling end 7.4.4. Again, this is for friction-reduced

 Motion sequence stored in a bearing point 7.4.5

Roller 7.4.6 as an abutment and rolling element on the complementary, the drawer associated contact surface provided.

To trigger the opening process for the drawer a lever assigned to the drawer 12.10, corresponding to the lever end 12.1.3 in Figure 1, the furniture part enabling means 12, which at the same time also the

Form locking mechanism for the energy storage 4 (see Figure 6). Accordingly, in the same way therefore also include this furniture part-release means or these

 Locking mechanism similar subcomponents. These include one by the lever 12.10 and an intermediate one

Sliding element 12.10.1 in its pivotal position by one

Pivot point 12.11.1 according to the direction of the arrow 12.11.1.1 deflectable pivot lever 12.11. The pin-shaped, for example, at its lever end 12.13 detent means comes out of engagement with the complementary, the

Lever end 7.4.4 assigned, here by way of example hook-shaped locking means 12.15 and thus gives the in

 Energy storage 4 stored energy to open the drawer, as shown in Figure 4, free.

In order to enable a clean drawer slide and in particular a perfect control during the charging of the energy accumulator 4, in addition to the loading wedge already described as 7.5.3 Spannkeil 7.5.3 further charge control means may be provided in the form of support rollers 8.2, where the clamping wedge back supported when you pull out the drawer and run guided. Advantageously, these support rollers can be arranged on the base support 7.4.10.

 pivots the pivot lever 7.4.1 in the direction of

Arrows 7.4.1.1 (Figure 4). The drawer is in this state due to a corresponding adjustment of a mode selector 13 (see Figure 6) in its displaceability is not limited by a Ausfahrweg-limiting means, but can in this operating mode in their entire extension length free to be moved. Thus, the user of this drawer immediately after activation of the furniture part enabling means 12 corresponding to the opening width of the drawer access to its interior and the content therein, if necessary. This can be advantageous, for example, in ample space. The complementary operating mode with limited

Ausfahrweg after activation of the furniture part enabling means 12 will be described later with reference to further figures in more detail.

A for charging the force accumulator 4 during a

Opening operation of the drawer 2 provided charging control 8.3 is here as a to a fulcrum

pivotally mounted locking element 7.6 and trained

is set to its inactive mode due to the presetting of the mode selection means 13. Its main body is formed by a pivoting lever 7.6.1, the further

Pulling out the drawer 2 according to the illustration of Figure 5 in the direction of arrow 7.6.1.1 due to its investment in the control cam of the clamping wedge of this forward towards drawer front panel against the force of a

 Return element 7.6.4 is pivoted.

As long as the drawer 2 is not pulled out so far that the blocking element pivots back due to the restoring force acting on it behind the guideway of the clamping wedge 7.5.3 in the direction of arrow 7.6.1.2, the drawer can

 Essentially freely pulled out or inserted again. Only after folding the locking element 7.6 and

 Pushing back the drawer 2 in the closing direction 6 presses the leading edge of the clamping wedge 7.5.3 the locking element 7.6 and thus connected to the power storage 4 and the locking element 7.6 bearing pivot lever 7.4.1 in

 Closing direction of the device. 1

For a low-friction movement of the loading control means 8, here in the form of the locking element 7.6, can, in accordance with the item 7.1.11 in Figure 1, here also a mounted on a pivot point 7.6.4 7.6.3 be provided.

After locking the latching means 12 and the furniture part unlocking means 12 of the energy storage 4 is fully loaded again and stored by the latch the impressed him during charging energy to the next pushing out of the drawer 2 on call. The drawer can be freely opened and closed in this state. If the drawer is sufficiently closed, a designated automatic catch mechanism can do this

capture and soft and retracted so that the entire assembly is again in the position shown in Figure 3 in the closed rest position.

With regard to a non-illustrated training as a separate assembly for the device 1, the

Basic support 7.4.10 for its attachment z. B. to the

 Carcass rails of the guide units 20 in a preferred manner to corresponding receptacles 20.1 (Figure 3) simple,

 in particular tool-free, slid and latched to be clipped. The receptacles 20.1 are present here on the underside at the front attachment angles of the carcass rails.

The fixing 7.4.10.1 can be formed, for example, as inwardly facing locking lugs 7.4.10.1.1. You can when sliding the basic carrier 7.4.10 on complementary, z. B. angle-shaped receptacles 20.1.1 be pressed outwards and rest when sliding the rear edge back down and fix with their hooks

 Mounting adapter 7.4.10.1 and thus over the base support 7.4.10 so attached the components of the

 Device 1.

The mounting adapter 7.4.10.1 can be exemplary for a

 tool-free installation via a so-called

 Mounting groove 7.4.10.1.2 pushed onto the receptacle 20.1.1 and latched to it with the latch 7.4.10.1.1.

The attachment of the example as a separate trained, a clamping wedge 7.5.3 comprehensive power reduction means 9 can be realized in a corresponding manner. Preferably includes a floating storage of this assembly, z. B. to eliminate lateral forces and / or transverse offset in the device 1 and / or the furniture part. The power reduction means 9 can be applied to the

Force accumulator 4 with the for an opening process

energy required to reduce the effort required for the operator.

The base plate 7.5.10 for the clamping wedge 7.5.3 may have a series successively each oriented in the opposite direction, angularly projecting receiving elements 7.5.10.1, 7.5.10.2, which has an exemplary rail guide for a

aufzuschiebenden Spannkeil 7.5.3 can represent. Between the end faces of these receiving elements can in

Lengthwise, due to their mutual spacing, recesses 7.5.10.4 be formed in an exemplary grid system "X". This allows a variable

 Longitudinal positioning of the aufzuschiebenden on this

 Clamping wedge 7.5.3 by appropriate positioning of his example as a spring-loaded latching arm 7.5.3.3 locking means formed in one of these recesses 7.5.10.4.

The fixation between clamping wedge 7.5.3 and 7.5.10 base plate can by adjusting, for example, on the clamping wedge formed as complementary angle arms fixing in the rail guide 7.5.10.1, 7.5.10.2 of the base plate 7.5.10 both adjustable in length and by constructive

 provided distances "Y" be floating in the side guide of the fixing of these two elements. In a suitably provided game between a

 Retaining tab 7.5.3.3.1 of the spring-loaded locking arm of the clamping wedge and the recesses receiving it 7.5.10.4 can also in

 Longitudinal direction of the clamping wedge a corresponding floating storage can be realized.

A floating mounting of the clamping wedge allows its exact guidance in a pull-out or insertion movement of the movable furniture part, especially in his

Relative movement relative to serving as a loading control means support rollers 8.2 and the voltage applied to the opposite wedge side roller 7.6.3. As a result of this floating mounting of the clamping wedge, it is possible to prevent a transfer of any transverse forces which might occur to the movable furniture part 2 and thus a lateral position offset which is possible as a result. The drawer and its front panel can thus always exactly in the originally aligned position with respect to the receiving furniture 3 trouble-free

remain.

FIG. 6 shows further details of the charging mechanism 7 and in particular of the mode selection means 13, by means of which an activation or deactivation of

Opening path limiting means 14 for the furniture part. 2

can be made.

As a mode-selector 13 is exemplified a "rotary switch" with on a cylindrical base body frontally

 arranged, hook-shaped locking element 13.1

 realized (see Figure 10). This accesses depending on Drehstellun the mode-selecting means 13 according to one of the directions of rotation according to the arrow 13.3 in a complementary, here

 by way of example also hook-shaped on the pivot lever 7.4.1 trained locking element 13.2 or is, as in the embodiment shown in Figure 6 out of engagement with this. A rotation limiting means in the form of a groove-shaped at an example on the cylinder circumference

 trained groove can with appropriate system against a stopper a positioning aid for a correct

 Positioning of the latching hook 13.1 in the locked position of the rotary switch in the engaged position with the complementary latching hook 13.2 realize. The same can apply to the unlocked rotational position. The abutment of the rotation stop can be realized, for example, in the form of a arranged in the lever 7.6.1 fixing pin 13.5.

When the locking hook 13.1 is engaged with the is complementary locking hook 13.2, is the

Lever 7.6.1 blocked. He can not do that anymore

Swivel axis 7.6.2 pivot, as shown for example in Figure 5, but is in this case with the roller 7.6.3 on the relevant edge of the

Spannkeils 7.5.3, which thus forms a second Öffnungsweg- limiting means 14, and thus inhibits the

Opening movement of the furniture part to be opened 2. Comparisons., For this purpose, the later described in more detail representations in Figures 11 and 12th

With regard to FIG. 6, attention should again be drawn to an adjustment possibility for the width of the "front gap" 2.10 between the furniture carcass or the furniture 3 and the front panel of the furniture part 2 by the positioning means 18 shown here by way of example in the form of an eccentric solves the lever 12.10 of the furniture part unlocking means 12 by pressure transmission over the

Slide 12.10.1 the interlock between the two

Locking elements 12.15 and 12.13 by corresponding pivoting of the pivot lever 12.11 in larger or

 smaller "front gap" 2.10 out.

In the lower view, shown in FIG. 7, of the furniture part 2 which is movably guided on a piece of furniture, the mode selection means 13 is set such that the opening-path limiting means 14 are activated. That means that the

 Lever 7.6.1, as described above, is locked in a stable position by the locking of the two locking hooks 13.1 and 13.2. Swinging when touching the

 Roller 7.6.3 with the swivel wedge 7.5.13, as shown in Figure 5, is thus no longer possible.

In order to prevent an abrupt stop of the opening movement, the clamping wedge 7.5.13 in its contouring and / or in its orientation with respect to the direction of movement of

 Furniture part and / or in the texture of his

 Control role associated flanks and / or in his

Material choice to be designed accordingly. In the in the 7, it has, by way of example, three area sections I to III along its control edge associated with the roller. According to the oblique top view in FIG. 8, a so-called "self-locking area" for the movable furniture part is defined in the front area I lying on a wedge tip. For example, one possible embodiment is the corresponding rolling resistance

being the surface's surface Shore hardness. As a result, the roller can slow down when running along and at

corresponding balance of power in the relevant

Remain in position. Another possible embodiment can be realized in providing a correspondingly elastic side restoring force which is able to fix the roller in a corresponding position.

Section I is followed by a so-called "Spannbereich" II, the

preferably smooth and correspondingly stable for clean support of the impeller when re-tensioning the

Force accumulator 4 guaranteed. This area ends

preferably at the thickest point of the clamping wedge 7.5.13. It is followed by a so-called "mounting area" III, which has a gradient opposite to the first area, and

thereby tensioning the force accumulator during a

 Closing movement allows. This may for example be the case during assembly of the movable furniture part, ie

for example, when inserting the drawer. Another application would be a changeover of the mode selection means 13 to a deactivated state, so that the opening-path limiting means 14 are deactivated.

To avoid a so-called "springback effect" can

Further blocking means may be provided which, according to the representation of FIG. 9, is designed, for example, in the form of a support roller provided with a freewheel. By using a freewheel, the roller can run along in the clamping direction and block in the opposite direction. This type of kickback avoidance can be provided both when loading the force accumulator in the extension direction and when loading the force accumulator in the direction of insertion. In FIG. 10, the part of the device 1 relating to the locking is enlarged and the mode selection means 13 is shown in locked position, that is to say the opening path limiting means 14. The hook-shaped

Locking mechanism 13.1 engages in the complementary, also hook-shaped on the pivot lever 7.4.1 formed locking mechanism and thus fixes the lever 7.6.

In the figures 11 to 15, the movement of the

Device 1 or the movably guided on the furniture 3

Furniture part 2 from its closed rest position, as shown in the figure 7, by activation by means of a pressurization "push" and thus taking place

Activation of the furniture part by activation of the furniture part unlocking means 12 and the entire following

Movement, up to again repositioning by means of a preferably provided, not shown here, automatic retraction into the original starting position of the furniture part 2. Accordingly, the figure 11 shows the

 Drawer 2 according to the arrow "P" with pressure

impinged against the body of the furniture 3 pressed so that the locking mechanism 12, the same time the

 Furniture part-release means 12 represent, is unlocked. The so released, stored in the energy storage 4 energy pulls the accumulator spring 4 together and pivots the

 Swing lever 7.4.1 in the direction of the arrow 7.4.1.1, so that the roller 7.4.6 on the extension of the angle-shaped

 trained trigger lever 10.12 rolls along and the

 Drawer 2 imprints its opening acceleration until it is braked by stopping the second roller 7.6.3 on the clamping wedge 7.5.13, as described above, and then stopped.

FIG. 13 shows the movement section of the drawer 2, in which the energy accumulator 4 due to the back pressure of the

 Clamping wedge 7.5.13 against rolling on its control edge roller 7.6.3 by pulling it out forming

 Spiral spring 4 loads as long as the

Locking device 12 is locked again. Subsequently, the drawer can be moved freely in and out, as shown in the figure 14.

In FIG. 15, the last movement section is the

Drawer 2 in the closing direction when fully charged

Force memory 4 shown, preferably by the

Actuation of a retraction automatic, not shown here can take place.

FIG. 16 shows the situation in which the drawer is pushed in the direction of the arrow 5 when the device is unlocked, that is to say when the energy store 4 has been unloaded. In this case, the roller 7.6.3 runs along the rear, short slope of the clamping wedge 7.5.13 and pivots the pivoting lever 7.4.1 in the closing direction and thus biases the force-storing spring 4 fastened at the opposite end.

FIG. 17 shows an operating situation in which the drawer opened by the ejection mechanism in the form of the device 1 is not to be opened any further but is closed again. For this purpose, the security and emergency charging mechanism already described in detail in FIG. 2 is used. The operation is appropriate. The supported by the retaining pin 7.3.1.2 rocker arm 7.3.3 serves as an abutment for the drawer associated sliding or rolling surface in the angled

 Extension of the activation lever 12.10 for the furniture part unlocking 12. When pivoting the pivot lever 7.4.1 this precedes serving as an abutment contact surface of the rocker arm 7.3.3, so that the locking mechanism 12 already locks before the release lever 12.10 the rocker arm 12.11 to reopen the Drawer back in

 Unlocked pivoted position.

The projection of the rocker arm 7.3.3 from the contour of

Swing lever 7.4.1 can be done by acting on a corresponding force, which attacks here for example outside the pivot point 7.3.4 on the rocker arm 7.3.3 and pulls it outward. A swinging within the Contour of the pivot lever 7.4.1 is prevented by the abutment in the form of the retaining pin 7.3.1.1. The provision of provided on the elastic elongated extension 7.3.1 retaining pin can be done after the end of the application of force to the rocker arm by the inherent in the elastic, elongated extension retraction force. Its rest position corresponds to that shown in Figure 1 and in this respect already

detailed position.

The here described with respect to a movably guided on a furniture 3 furniture part in the form of a drawer described

Device 1 is in each case designed so that it is in

front, the front panel of the drawer facing area of the furniture is to be arranged.

In contrast, modified embodiments of

Devices 1, these can also be arranged in the rear region of the movably guided in the furniture 3 drawers.

Again, the energy storage 4 when closing the

 Drawer 2 will be loaded and / or when opening the drawer.

The relevant devices 1 work analogously as described above for the embodiment according to FIGS. 3 to 5. Also, the structural features may be mutatis mutandis at least similar. So can the

 Charging mechanism 7 for the energy storage 4 a

 Swing arm 7.10.1 corresponding to the swing arm 7.4.1 include, as shown in Figures 3 and 4. This can also be locked by means of a locking device 12 or furniture part unlocking means 12 and acted upon by the stored energy in the energy storage 4. By pressing a release lever 12.10 can by a

 Positional shift of the individual rocker arms

 Lever mechanism 12.1 the hook-like design

 Lock 12.12 be disengaged, so that stored in the memory spring 4 energy over the

Lever mechanism of the lever arm 7.10.3 and the lever 7.10.1 pivotally connected to it via the pivot point 7.10.2 by swiveling out as the ejection energy for the drawer 2 can be released.

Also in these embodiments, the components of individual position groups can be formed separately and mounted on a base support, which in turn at the

Bottom of the drawer 2 is attached. Its positioning relative to the drawer 2, for example, to adjust the "front gap" 2.10 between the front panel of the drawer and the furniture 3 based on the positioning means 18, which may also be an eccentric here set.

In accordance with the embodiment according to Figures 3 and 4, for a lateral force-free support of the

 Recharging mechanism 7 in this case a floating-mounted clamping wedge 7.11.3 between one of its control edge 7.11.3.3 associated roller 7.10.7 and two of the opposite back of the clamping wedge associated support rollers 8.2 be performed. Support rollers 8.2 can outwardly from the

Neutralize the roll on the key, its floating bearing can allow for positional adjustment without changing the relative position between

Furniture 3 and drawer 2 to influence.

A roller mounted transversely displaceable to the extension direction can during the run through the pivoting of the lever arm on the control edge of the clamping wedge and thereby move according to its decreasing in its width contour toward the opposite her support roller 8.2. This transmitted via a slider

 Transverse movement of the roller with respect to the drawer movement is in the restoring force, a drawn by the contraction of the energy storage spring 4 in the length and thus acted upon with restoring force second, also

 non-positively connected to the lever spring. This second spring controls the relative position of the energy storage spring 4 relative to the base carrier carrying it and thus forms a charge control means 8.

Due to the relaxed state of the energy storage spring. 4 can then act the energy stored in the second spring and pull during the ejection movement of the drawer 2 via the slider against the control edge of the clamping wedge.

About a lever mechanism while the lever back in

Towards closing state, he moved to

completed swivel movement with locked

Locking mechanism 12 or locked Möbelteil- release means 12 can take.

In this position, the energy storage 4 is discharged. The

Drawer can, if it allows its run length, free

pushed in or pulled out.

The storage of the energy required for the next ejection of the drawer in the power storage 4 can be done by inserting the drawer 2 in the closing direction, so that the roller by the increasing in the closing direction width of the clamping wedge and rolling on the control edge of the slider again against the memory spring of the fourth presses applied force and thus pre-tensioned until the

Roller has reached the widest point of the clamping wedge.

The width contour in the plan view of the clamping wedge determines this as a force translating means of the user

 applied force to re-storing the energy required for the next process in the

 Force memory 4. A support in imprinting this force can be done by the kinetic energy inherent in the moving drawer. In the event that this

 Kinetic energy is too low to tension the power storage 4, the user must overcome the missing insertion path by inserting the drawer. In excess

 Energy can do this by a preferably provided

 Damping mechanism be taken out of the system. In particular, the last section of the closing process is advantageously carried out by means of an automatic retraction mechanism.

With such an embodiment, a device 1 can be realized with which the movably guided on the furniture Furniture part 2 when unloading the energy stored in the energy storage without limitation by Öffnungsweg- limiting means to exhaustion of their inherent energy can be freely opened.

A mode selection means 13 for activating or deactivating opening-path limiting means 14 can be used in this

Embodiment in the form of a conversion element, for. B. can be realized with a second (control) roller arranged thereon. For the deactivated mode of operation, the mode selector can be arranged, for example by means of a screw detachable in an extended position to the slide. To activate by this second roller

formed opening path limiting means 14 may be on one of the first (power transmission) -Laufrolle

opposite extension of the pivot lever are mounted, in particular preferably by tool-operated fixative. The previously releasably fixing the conversion element screw can in this case for releasably fixing the ineffective in this mode of operation slide 7.10.5 for

To be available.

By such a conversion, a further element group for the charging mechanism 7 can be realized, which corresponds mutatis mutandis to the position shown in Figures 7 to 10, fixed by the mode selector 13 position 7.6. Both

 Embodiments are designed so that they

 Load energy storage device when opening the drawer. Also, the relevant clamping wedge can be stored in the fixing points floating on the fixed to the furniture 3 base support 7.12.10 and the extension of the drawer from running on its control edge along roller 7.12.2 for

 Reloading the stored energy 4 impressed clamping force on the two at the back of the clamping wedge

 Support support rollers 8.2. As a result of this, as already explained in the above embodiment, a lateral force-free one is also possible

 Drawer movement when charging the energy accumulator 4 possible.

By the concerns of the second roller on the control edge the clamping wedge, in turn, an opening path limiting means for this embodiment is realized. For the control cam of the clamping wedge applies mutatis mutandis, the same facts, as already set out above with reference to Figures 7 and 8. The charging of the energy accumulator 4 can be done accordingly in the appropriate manner when pulling out the drawer, in which the overall arrangement has balanced power ratios and, accordingly, the drawer after the initial

Opening process has come to a standstill.

From this position, the drawer can be freely moved out and in with respect to the furniture carcass, provided that its pull-out path allows this. The drawer is closed by inserting it into the cabinet 3, wherein here too the final slide-in movement can be effected by an automatic retraction mechanism in a particularly preferred manner.
