Description

Tilting and rotating window with device drive.

The invention relates to a tilting window and rotating for a building, with at least one sheet that is pivotally arranged in a window frame and with a drive device for automatic movement of the sheet relative to the window frame and a device drive according to claim 1.

The idea of automatic opening and closing of windows and doors (which also include hatches) of Buildings are known from the state of the art. So, the document DE4131762 shows a drive for a door or door leaf a ventilation hatch or the like, in which a housing of drive is arranged on the sheet to be folded in the upper horizontal stringer. From the drive housing at least one chain is guided, designed so that it forms a pressure stable element that opens the blade when removed from the drive housing. The closing is done when the chain.

This drive works satisfactorily, but it needs too much constructive space, especially because the chains must have a relatively large dimension to ensure the required stability.

It is also problematic that, for example, when the blade is opened by turning it is necessary to undo the chain in the window frame and / or the leaf frame, which in certain circumstances is difficult to perform and manipulate from the mechanical point of view.

Also, document DE3844101 discloses a electromechanical device to close and open a window with a drive unit that can also be placed on the sheet the window, and a spring construction that presses constantly the window leaf in the direction of opening.

Documents DE19949940A1 and DE19949941
A1 refer to opening devices, driven by motor, for rotating and tilting windows in which the drive device is mounted on the window. The drive device engages by means of a drive element in a pin of the groove of the frame in the frame of the leaf, which is provided with control pivots that engage in a control cam of the arm of the opening device. By means of the linear displacement of the pins, the control pivot is guided along the control cam (slider) and thus causes a corresponding movement of the window leaf opening in the upper horizontal area.

Both the opening and closing movement The window leaf is made by permanent engagement by dragging the control pivot on the control cam of the opening arm, which requires, on the one hand, due to the friction a high energy expenditure of the drive and, on the other part, causes the problem of great wear on the surfaces guide cam control.

It is especially problematic that the control cam can be provided very close to the point of joint, located on the side of the blade, the compass arm and this results in an unfavorable lever ratio for the opening movement and especially the necessary surfaces of closure, which conditions, among other things, the high expenditure of Energy.

While the opening process is supported by force drag by the joints between the window frame and the frame of the leaf and its claim, as well as by the weight of the sheet to be struck down in each case, these forces act against the closing movement. Due to the unfavorable relationship of lever relative to the position of the slide guide relative to the articulation point of the compass arm window frame, the closing function cannot be executed or can only be executed with difficulty through actuation. The forces in the guide of sliding increase in correspondence with this, leading to wear and also causing deformations in the device opening, which prevent the exact closing.

The invention wishes to largely solve the previous problems

Therefore, the object of the invention is provide the generic type window with a device drive that can be performed in a special way compact and nevertheless have a safe operation, as well as that can easily be accommodated in the window. It must also be created a corresponding drive device.

The invention achieves this objective in relation to with the double tilting window through the object of the claim 1.

According to this, the drive device presents a power and energy accumulator that is designed and ready to open the sheet. The power and energy accumulator it can have an especially compact design with space saving and can be housed in the window, especially in the sheet, and this one offers high safety in use and operation, as well as high precision of movement with small wear.

With special advantage, the force accumulator and energy is used exclusively to open the window or door and the closing of the window or door is done with the help of a flexible traction device, especially an element of motor-driven cable traction. For closing only, the force and energy accumulator, as well as the traction device They can have an especially small and compact design. It is also it is possible to arrange the cable tension element separately and the accumulator of force and energy in (almost) any zone and take advantage of space in an optimal way existing construct to accommodate these components. He flexible traction device not only closes the window, but recharge the power and energy accumulator again or It moves back to its position of energy accumulation.

However, it is also conceivable to use the accumulator during window or door closure individually or as support, although the use variant is preferred for opening In the latter case you can take advantage of the effect advantageous that usually only a small force is needed to bring a window or a door to a down position. This It is valid in any case when during the movement to the position downcast, the force of gravity or the weight of the blade can act as support, if necessary, reinforced by a certain elastic force of the joints between the window frame and the sheet. The resort it should support the opening movement until the maximum collapsed position and additionally hold the window in the open position, for example, to also prevent air currents move it or even the air sucked at once or the closing

The accumulator of force and energy can be Easily perform as spring. The springs are usually Very compact, economical and maintenance free. In this sense is especially advantageous that the spring is a spring helical or a leaf spring. The spring can be alternatively also a bending spring. They're possible also other pressure springs, especially the springs of gas pressure

According to a variant of the invention, the drive device preferably comprises the flexible traction device already mentioned, especially in Shape of a cable pull element with a cable. Given the the opening of the window or door is done differently, especially through an accumulator of force and energy, it is no longer it is necessary to use a rigid flex chain to open the window. For the closure it is surprising, surprisingly enough, also a flexible traction device, especially the cable pulling element that can be realized in a way Especially economical and compact. The traction device is can use or can act here also directly as an element opening limiter The drive device presents in this case preferably an electromotor drive for actuate the traction device.

It is also possible alternatively that the electromotor drive act directly on the accumulator of strength and energy to push it back to its position of accumulation of energy after a separation.

The cable of the cable pull element may have a round or shaped configuration.
band.

Between the sheet and the window frame is arranged an opening device that is reconfigured  in a simple way as an opening measure that presents with preference a main compass arm and a secondary arm of compass, especially so that the main compass arm is arranged by one end pivotally in the window frame and at its other end pivotally in a compass housing, as well as scrollable in the frame of the leaf.

Strength and energy accumulators can act directly on the opening device, which is possible to perform especially simply and compactly from the constructive point of view, or, for example, on the framework of window or on an axis of rotation between the window frame and the leaf. Depending on the layout, a higher or lower elevation is required and lever and force ratios vary, which requires a corresponding sizing of the components.

The accumulator of force and energy can act advantageously directly on one of the compass arms of the opening measure, which is especially easy to make and assemble thanks to the invention, especially if the force and energy accumulator is designed as a spring arranged between the leaf or the window frame and the opening compass. He spring can be arranged alternately between the arm main compass and secondary compass arm.

The spring is preferably a spring helical that rests on the blade and on the axis of rotation of the arm secondary beat.

It is also possible that the device traction act between one arm of the opening device and the sheet.

The flexible traction device is fixed especially at one end of one of the compass arms, in special, on the main compass arm, and at its other end in a winding coil in the sheet, which can be operated Rotating by electromotor drive.

The drive device is designed preferably as a preassembled unit and preferably arranged on the sheet, so that in the window assembly it is no longer It is necessary to mount any drive device. If he drive device acts on the hardware (that is, the opening device or hinge), a window or door mounting that does not differ from that of a window or a door without a drive device or that does not require additional work steps.

The traction device is fixed advantageously in the middle of the main compass arm, which is located towards the articulation area of the compass arm in the window frame, especially in the last third of the arm Main compass towards the window frame.

In the remaining subordinate claims other advantageous configurations appear.

The following describes in detail the invention using exemplary embodiments on the basis of He drew. Sample:

Fig. 11 a section through a element of the window frame and the leaf of a tilting window  and rotating.

Figure 1 shows by way of example a called a tilting and rotating window in the ventilation position  (in this case with an opening angle between the window frame and the sheet <30º), which is provided with a device drive, according to the invention, for drive automatic.

The terms "above" and "below" are then refer to the mounting position shown in the Figure 1 and should not be understood as a restriction. Window swingarm has its X axis of rotation usually "down" and a folding window, on the contrary, "up". In this case The provision in Figure 1 should be adapted accordingly. A tilting and rotating window allows an opening around of two alternative axes, usually around a lower axis "X" and around an "Y" axis of rotation in one of the sides.

The tilting and rotating window has a window frame 2 and a sheet 1, the sheet 1 being supported so pivoting in window frame 2 on at least one of its sides or, according to figure 1, on two sides. Sheet 1 presents a frame 35 of sheet and can be provided with a crystal.

On its side opposite the axis of rotation is located between the leaf and the window frame an opening device, set in the form of a 3-bar opening. Compass 3 of opening features a 4-arm main arm with one end rotatably fixed in window frame 2, in this case, in the upper angular area of the window frame, and with its other Guided end rotatably as well as movable in a slide 30 of a bar type 6 bar housing, which is fixed in turn on the upper side of sheet 1.

Between the two ends of the main arm is articulated to the main arm 4 of compass one end of an arm secondary 5 bar, whose other end is articulated in turn in a rotating, but not movable way, in the compass housing 6. The pivot axis 13 of pivot form of the secondary arm 5 of compass on sheet 1 crosses the compass housing 6.

In Figure 1, one end of the secondary arm 5 measure is set approximately in one arm area main 4 bar, found here as an example, but favorably from the point of view of the relations of lever, approximately one third of the arm length main measure between sheet 1 and window frame 2.

When the window is opened, as well as when the window, the end of the main arm 4 of the compass, supported by the sheet frame in the compass housing 6, is moved by a rotating movement along the slide 30 of the compass housing, since the secondary arm 5 of compass presses the main arm 4 compass off sheet 1. This increases the angle between the main compass arm 4 and the window frame 2, performing, on the contrary, a reverse movement at close the window

The opening measure 3 guarantees a movement controlled from sheet 1 to the collapsed position when opened and tilt and swivel window close, as well as especially also precise positioning of sheet 1 relatively with respect to the window frame 2 in the closed position. Result theoretically possible to open the window to its turning position with a conveniently transformed arrangement and close it from it (no represented here).

Figure 2 shows a representation individual of the opening device of figure 1 in position closed corresponding to the closed position of the window tilting and rotating.

On the side, lower in the mounting position, of the compass casing 6 a casing 7 of drive used to house an electric motor, not visible here, if necessary, with the gear.

The drive housing 7 can be fixed together with the compass housing 6 on sheet 1 by means of an element common fastening, for example, by interlocking, screwing and / or a gear in a chamber or an open side wall of its own frame 35 of the sheet (not seen in figure 2).

According to figures 1 and 2, the housing 7 of gear drive in a wall notch of frame 35 of the sheet and is covered, otherwise, largely or completely using the compass case 6.

In case 6 of bar type compass is fixed and guided a slide bar 8 of the opening device. One end of the slide bar 8 is attached to a bar Sliding hardware 9 of a locking hardware not shown here for the rest. At its end, opposite the sliding bar 9 of hardware, the slide bar 8 is guided, provided with several notches, which remain on the sheet when the window is opened tilting, up in front of the arm joint area main bar 4 in window frame 2, which is articulated to a swivel joint 31 in the form of a band or hinge in the window frame 2. The slide bar 8 comprises in the form of frame the compass housing 6 and extends to a pin 10, in which it can engage, causing a lock, a bolt 11 of closing of the main compass arm, positioned near the area of articulation of the main arm 4 of compass with respect to the frame of window.

The interaction of the elements derives from the combination of figure 2 with figure 3 showing the opening device 3 in its open position, corresponding to the open position of the tilting and rotating window. Arm main 4 bar is pivoted out in this position by means of the secondary arm 5 of compass, moving, in this case, by retracting a pivot 32 in the slide 30 of the housing 6 measures The slide 30 limits the movement of the arm main measure 4 and, therefore, the opening angle of the tilting and rotating window.

To open and close window 1 use the drive device 40 housed here in the form sheet Especially compact and space saving.

The drive device 40 presents, by one part, an accumulator 12 of force and energy to open the tilting and rotating window and, on the other hand, a device flexible traction to close it.

As accumulator 12 of force and energy result suitable, for example, the springs, being selected in the Figures 2 and 3 as a force and energy accumulator a spring helical 33, especially suitable here due to its low cost and Its compact geometry.

Helical spring 33, which is supported by a end on a pivot 34 of the compass housing 6, acts according to the Figure 5, with its inner end directly on the axis 13 of turn of the secondary arm 5 of compass, which is fixed in this last torsionally resistant, and thus causes to separate a rotation of the axis 13 of rotation and, therefore, an opening of the compass 3 opening.

Consequently, the window opening is achieves more easily without external power supply or without the use of an engine, only with the force accumulator 12 and energy, supported, if necessary, by the force of gravity.

It is proposed to additionally provide the device 40 for driving an electromotor drive that causes the closing of the window and, therefore, also a tension of the spring or the accumulation of force and energy in the force accumulator 12 and Energy.

To perform the closing movement is provided, according to figures 1 to 6, a flexible device of traction which is configured as traction element 14 by cable and can be done especially economically and compact Alternatively you could also use a band or a chain (not rigid to slip) as a traction device (not represented here). As material for item 14 of Cable pulling is proposed steel, preferably steel fine, or natural or synthetic materials, especially fibers natural or synthetic

One end of the cable pulling element 14 It is articulated in the main arm 4 of compass. The cable of cable pulling element 14 is then extended in vertical to the frame 35 of the sheet or to the compass housing 6 before be guided at a right angle around a diversion device in shape of a deflection roller 15 and then guided in parallel to the sheet frame to a winding coil 16 in the housing 7 drive (see also figure 6), which is supported by the compass housing 6 and can be rotatably operated by means of a drive with an electric motor, arranged in the drive housing 7. Pivot 34 of Figure 5 serves also as a support pivot for the deflection roller 15 in the opposite side of the compass housing 6.

A special advantage of the provision lies in that the traction device can be positioned regardless of the power and energy accumulator 12 and accommodate so as to save space, as well as optimize strength. It would be possible even a separate arrangement of the device opening if there is not enough space in your area constructive.

The arrangement shown in Figure 3 is especially easy and compact, it saves constructive space and surprisingly enables the accommodation of almost all essential elements for operation as a unit construction directly mounted on sheet 1 (especially together to frame or frame 35 of the sheet). You just have to articulate the main arm 4 of compass in window frame 2.

Theoretically there is also the possibility of also use the deflection roller 15 as a winding coil, so that the traction device would act directly without deviation on the articulation pivot 17 that serves as a point of contact in the main arm 4 of compass. However, the arrangement shown in figures 3 to 6 seems more advantageous, since that the tractor effect of the traction device in the direction Longitudinal drive unit enables a most optimal transmission of force to the electromotor drive and this can be arranged separately from the force accumulator 12 and energy, thus optimally taking advantage of the building space available, small in general, on sheet 1. The sizing of these constructive elements can be minimized by a proper arrangement of the motor drive housing 7 electrical, as well as by proper selection of the point of transmission of the force of the cable pulling element 14 into the main compass arm, as well as the roller 15 of deviation.

Figure 7 shows an alternative form of embodiment of a drive device 40, in which in the drive housing 7 is provided with a winding coil 19 which houses two cable tension elements 14, 14 'that are they wind in the opposite direction in the winding coil 19. Of this mode two traction devices can be used, for example, in tilt-and-turn leaf windows (otherwise, no represented).

Figure 8 shows a tilting window only, which is indicated by the axis 20 of rotation. In the case of a window tilting, the energy and force accumulator with a corresponding sizing and design could also act directly on the "fixed" axis 20 of rotation (otherwise, no represented).

Figure 9 shows an opening measure 3 with main arm 4 of compass and secondary arm 5 of compass that can pivot relatively to each other by a pivot 36 that It serves as the axis of rotation. Around the pivot is rolled a bending spring 37 as a force and energy accumulator, whose two ends are fixed on the main arm 4 of the compass and on the secondary arm 5 of compass. This way they could be arranged one or more bending springs in any element of windows or doors to open them. However, it is especially advantageously the selected arrangement in an opening measure.

Figure 10 shows another variant, in which a V-shaped bending spring 38 is directly arranged between an opening arm 21 and a basic hardware body 22 that could be in turn, for example, the main compass arm and an element of the sheet like the compass housing.

Figure 11 shows with the help of a cut a through the frame 35 of the sheet and the window frame 2 the compact arrangement of the elements such as compass housing 6 and the main arm 4 of compass in the frame of the leaf, as well as the arrangement, also with special space saving, of the housing 7 of actuation in a chamber 39 of the frame 32 of the leaf.
