DESCRIPTION

Door fastener for a furniture door

The invention relates to a door fastener for a furniture door, which can be moved between a closing position that closes a closet compartment in a furniture body and an opening position moved upwards, the furniture door being divided into two and being formed by an upper door part and a lower door part, which are joined together in an articulated manner on a hinge shaft, so that when they move from the closing position to the opening position they perform opposite pivoting movements , pivoting the upper door part away from the closet compartment and the lower door part on the hinge shaft towards the closet compartment, with a regulating lever to control the movement of the door, which on one side is connected to the body of furniture so that it can pivot on a first pivot axis and is indirectly connected with the lower door part, so that it can pivot on a second pivot axis, and with an adjustment device to adjust the position of the two door parts with each other and with respect to the furniture body, the adjustment device presenting a support element that can be joined with the lower door part and a adjustment element, which on the one hand is connected with the adjustment lever so that it can pivot on the second pivot axis and on the other hand to adjust the position of the furniture door is connected with the support element so that it can rotate to the desired adjustment position on a rotation axis, and fixing means are provided for fixing without the possibility of rotation of the adjustment element to the support element in the desired, established adjustment position.

WO 2007/041736 A1 discloses a door hardware for pivotally fixing a furniture door to a cabinet body, with at least one adjustment arm, which is intended to move the furniture door, and with the less a hardware part on the door side, which can be joined with the adjustment arm, the hardware part on the door side presenting a protection against rotation for the temporary fixing of the pivoted position of the at least one arm of regulation, preferably in its full opening position, retaining the protection against rotation in a first operational position the at least one adjustment arm in its pivoted position with respect to the hardware part on the door side and allowing in a second operating position a pivoting movement of the adjustment arm.

From WO 2006/039729 A1 a door fastener is also known, which is used for swing doors or two-part furniture doors. In this case, a variable length adjustment arm lever is provided, whose length and / or position of support point can be established with the furniture door closed. According to a first alternative this is achieved because two parts of the telescopic adjustment arm are provided, which to adjust the swing door perform a telescopic entry or exit movement, thereby regulating the length of the adjustment arm lever. With this pre-setting, which can be done with the furniture door closed, for example by pressing on the open center of the two folding door parts, then the door can be reopened and then the adjustment arm parts can be held. According to the second alternative, the position of support point, that is, the point of articulation of the adjustment arm lever in the door moves linearly. For example also by pressing on the open center of the swing door. Once the position of support point is reached, which corresponds to an exact support of the hinged door in the furniture body, it is fixed. In order for the position of the support point of the adjustment arm lever to move linearly and parallel to the door plane, it is necessary that the length of the adjustment arm lever can be varied.

Conventional swing doors without the possibility of adjustment generally have a single-piece adjustment lever to control the movement of the door. When it is desired to retrofit the swing doors, that is, to provide them with an adjustment possibility, then, according to the prior art, it is necessary to change the entire adjustment lever and place a regulation lever with variable length. This is complex and expensive.

US 6,243,988 B1 discloses a device for a closing element that can move vertically in a piece of furniture. The device has an adjustment element with a fixing pin, which is housed in an oblong hole curved concentrically towards the axis of rotation and which during the rotation made for adjustment is glided between the support element and the adjustment element .

Document FR 2 827 332 discloses a support device for mounting a shock absorber, the support device having a stationary base element and a pivotally mounted support element thereon, which in turn the damper is pivotally articulated. An oblong hole is configured in the support element, which acts in conjunction with a fixing element arranged in the base element.

The object of the invention is to provide a door fastener for a furniture door of the type mentioned at the beginning, which is of simple construction and with which the two door parts of the furniture door can be easily adjusted to each other and with regarding the furniture body.

This objective is achieved by a door fastener with the characteristics of independent claim 1. In the dependent claims perfections of the invention are represented.

The door fastener according to the invention is characterized in that the fixing means have at least one fixing pin, which is housed in at least one oblong hole configured in the support element and / or in the adjustment element, curved so concentric towards the axis of rotation and that during the rotation made for the adjustment it is gouted between the support element and the adjustment element, being possible in the desired adjustment position by means of the fixing pin a fastening without the possibility of rotation of the element of adjustment and the support element, prior fixing means being provided for the previous fixation of the adjustment element to the support element in the established adjustment position, desired before final fixing by means of fixing means, and comprising the fixing means pre-fixing at least one friction drag element, whereby the adjustment element is maintained in the desired adjustment position with friction drag in the support element, with a guide pin provided with the friction drive element being provided, which is housed in at least one guide housing as an oblong hole, configured in the support element and / or in the adjustment element , curved concentrically towards the axis of rotation, and which during the rotation made for adjustment is gouted between the support element and the adjustment element.

It is also possible to make an adjustment with the furniture door closed, for example in such a way that the two door parts are pushed towards a coplanar position with each other, so that they rest flat on the front surface of the furniture body. This adjustment can be done with simple means, specifically by rotating the adjustment element with respect to the support element, until the desired adjustment position is reached. In this respect, the position of support point of the adjustment lever, that is, the second pivot axis, can remain in a stable position. Therefore, a variable length adjustment lever is not necessary, but it is possible to place the adjustment device on a conventional, constant length adjustment lever. However, in principle it would also be possible to provide a variable length adjustment arm lever, then a double adjustment possibility will be available. Preferably, the adjustment lever is not directly connected with the lower door part, but by means of a fixing element, that is, indirectly.

Pre-fixing means are provided for the previous fixing of the adjustment element in the support element in the established adjustment position, desired before the definitive fixation by means of the fixing means. In this way, the adjustment position can be established, for example, with the door closed, this adjustment position being invariably maintained when the door is opened by means of pre-fixing means, until finally the final fixation can be made with the door open.

Especially preferably, the pre-fixing means can be operated without tools. For example, they can be operated by pressing on one or both door parts.

As a means of pre-fixing, at least one friction drag element is provided, whereby the adjustment element is maintained in the desired adjustment position with friction drag on the support element. Therefore, in order to pivot the adjustment element with respect to the support element, the friction force must first be overcome. Then, as a rule, when opening the door, forces appear that are less than the frictional force, so that the set adjustment position does not vary.

It is provided a guide pin that carries the drag element by friction, which is housed in at least one guide housing as an oblong hole configured in the support element and / or in the adjustment element, concentrically curved towards the axis of rotation, and that during the rotation made for the adjustment is gouted between the support element and the adjustment element.

The drag element is preferably composed of rubber material.

It is possible to operate the fixing means without tools or by means of a fixing tool.

Preferably, the fixing pin is formed by a separate component, which in addition to the oblong hole is still located in a through hole configured in the adjustment element or in the support element.

It is possible that the oblong hole is configured in the support element and the through hole in the adjustment element. However, alternatively it is also possible to provide the through hole in the support element and the oblong hole in the adjustment element.

Alternatively, it is possible to provide a fixing pin that is firmly connected with the adjusting element or the support element, that is, does not form a separate component.

Preferably the fixing pin is formed by a screw.

An example of a preferred embodiment of the invention is depicted in the drawing and will be explained in more detail below. In the drawing they show:

Figure 7, a side view of the adjustment device of the door fastener according to the invention and

Figure 8, the adjustment device of Figure 7 in an exploded representation.

Figures 1 to 6 show an example of preferred embodiment of the door fastener 11 according to the invention. The door fastener 11 is arranged in a closet, in particular a tall closet, which is fixedly suspended high on the wall of a building. The cabinet body 12 of the cabinet has two side walls 13 opposite each other, vertical, of which only one is visible in the drawing, a base wall 14, a ceiling wall 15 and a rear wall and contains a cabinet compartment 16 delimited by these walls, which may be subdivided in height by a compartment board 17.

A cabinet door 18 is associated to the front side of the cabinet compartment 16, which in its closing position that emerges from figure 5 adopts a vertical position and closes the cabinet compartment 16. The furniture door 18 can be moved from this closing position to an opening position (figure 1) that allows access to the cabinet compartment 16, the opening movement taking place through the intermediate position shown in figure 3 upwards.

The furniture door 18 is divided in two and is formed by an upper door part 19 and a lower door part 20, which are joined together in an articulated manner in a hinge axis 21. The hinge axis 21 is usually formed by two hinges arranged in each case in one of the two lateral end areas of the furniture door 18. The hinge may have an upper hinge part to be fixed to the upper door part 19 and a lower hinge part that it is to be fixed to the lower door part 20, which are articulated to each other by means of a hinge pin or the like that forms the hinge shaft 21. The two hinge parts can be fixed to the inner side of the door parts 19 , 20 directed towards the cabinet compartment 16. The hinge shaft 21 may be arranged near the joint between the two door parts 19, 20 or also with a certain distance above or below the joint.

The upper door part 19 is also mounted on the furniture body 12 so that it can pivot on an articulation axis 22. When the two door parts 19, 20 are moved to the opening position, they perform opposite pivoting movements, pivoting the part of upper door 19 moving away from closet compartment 16 and so! of the furniture body 12 according to arrow 23, while the lower door portion 20 pivots on the hinge shaft 21 towards the furniture body 12 in the direction of arrow 24, so that by! to say it folds the furniture door 18.

In at least one of the two lateral end areas of the cabinet a regulation lever 25 is arranged to control the movement of the door, which on the one hand is connected to the furniture body 12 so that it can pivot on a first pivoted axis. 26 and on the other hand it is indirectly connected with the lower door part 20, so that it can pivot on a second pivot axis 27. The adjustment lever 25 is configured as a single-piece lever with constant length.

An adjustment device 28 is associated to the adjustment lever 25 to adjust the position of the two door parts 19, 20 with each other and with respect to the furniture body 12.

The adjustment device 28 has, according to a first embodiment, a support element 29 connected with stable movement with the lower door part 20 and an adjustment element 30, the latter being connected on one side with the adjustment lever 25 in a manner which can pivot on the second pivot axis 27 and on the other hand to adjust the position of the furniture door 18 to the desired adjustment position is connected with the support element 29 so that it can rotate on a rotation axis 31.

The support element 29 is preferably configured as a plate and has a fixing part 32 for fixing to the lower door part 20 and a support part 33 oriented essentially perpendicular thereto for the support of the adjustment element 30. In the area of the fixing part 32 there are at least two fixing holes 34, which according to a first embodiment are configured as round holes. The fixing holes 34 serve together with fixing means not shown, for example screws, for fixing with stable movement, that is to say, relatively immobile of the support element 29 on the rear side of the lower door part 20. In a second embodiment represented with broken lines in figure 8 are provided fixing holes 35, which are configured as an oblong hole. These fixing holes 35 also act together with fixing means, in particular screws, in such a way that the support element 29 with respect to the lower door part 20 is slidably supported therein.

A support part 33 is essentially connected to the fixing part 32 at right angle. The support part 33 preferably has a trapezoidal shape and is joined in one piece with the fixing part 32.

In the lower area of the support part 33 is a round support hole 36, which in the assembled state is aligned with a support hole 37 also round, configured in the adjustment element 30. Through the two holes of support 36, 37 a support bolt 38 can be inserted, which at the same time forms the axis of rotation 31 between the support element and the adjustment element 30. Preferably, the support element and the adjustment element are joined together by middle of a rivet that passes through the two support holes 36, 37.

Above the support hole 36 of the support element 29 is a guide housing 39 as an oblong hole, concentrically curved towards the axis of rotation 31, which is part of the pre-fixing means, which are used for pre-fixing of the adjustment element 30 in the support element 29. The oblong hole-like guide housing 39 corresponds in the assembled state with a through opening 40 in the adjustment element 30. Through the mode-guided housing of oblong hole 39 and the through opening 40 passes a guide pin 41 which also belongs to the pre-fixing means, which carries a frictional drag element 42 in the form of a washer composed of rubber material. The guide pin 41 has a head 43, whose diameter is greater than the opening width of the guide housing as an oblong hole 39. The diameter of the washer is also larger than the width of the guide housing as an oblong hole 39. This has the consequence that both the head and the washer rest on the rear side 44 of the support part 33. The washer, in the fixed state, is secured between the rear side of the head 43 and a rear side 44 of the bearing part 33. Therefore, when pivoting the adjustment element 30 on the rotation axis 31, the frictional force between the washer and the rear side 44 must be exceeded.

Finally, in the upper area of the support part 33 there is an oblong hole 45 also curved concentrically towards the axis of rotation 31, which in the assembled state of the support and adjustment element 29, 30 corresponds to a through hole 46 configured in the adjustment element 30. The oblong hole 45 and the through hole 46 are part of the fixing means by which it is possible to fix the adjustment element 30 in the desired adjustment position in the support element 29 without possibility rotation. In addition to the adjustment means there is a fixing pin 47 in the form of a screw, for example configured as a screw with a cross groove, which passes through the oblong hole 45 and the through hole 46 and which during the rotation of the adjustment element 30 with with respect to the support element 29, the thread is glued in the oblong hole 45. Conveniently, a thread is found in the through hole 46, whereby it is possible to fasten the adjustment element 30 in the desired adjustment position by tightening the screw.

The adjustment element 30 is also plate-shaped and can be configured as an ellipse. However, in principle other configurations are also possible. In addition to the holes or openings 37, 40, 46 already described, the adjustment element 30 also has an additional through hole 48 in the upper area, which corresponds to an opening not shown in the adjustment lever 25. Through the hole through and the opening passes a pivot bolt 49, in particular a rivet, which forms the second pivot axis 27, whereby the adjustment element 30 and the adjustment lever 25 are articulated together.

When the furniture door 18 pivots from the opening position shown in Figure 1 to a stop position located after the intermediate position shown in Figure 3, the problem may arise that the two door parts 19, 20 are not correctly adjusted to each other or that do not rest exactly flat on the front surface of the furniture body 12. For example, it could happen that the lower end of the lower door part 20 rests on the front side of the base wall 14, but the furniture door as a whole will rise in the center, that is, on the hinge shaft 21 with respect to the cabinet compartment 16, that is, to open. Another undesirable state is also conceivable in which the furniture door 18 rests in the center, that is, in the area of the hinge shaft 21, although the lower end of the lower door part 20 rises with respect to the front surface of the base wall 14. When such an undesired state is observed, then it is necessary to correctly adjust the furniture door and the adjustment device 28 is used.

Therefore, the furniture door 18 is closed first and for example it is determined that it opens in the center. Then the furniture door 18 is pushed until it stops, that is, for example, with a pressure directed towards the furniture body 12 in the area of the center that opens. In this regard, the adjustment element 30 is rotated

25

on the axis of rotation 31 according to the arrow 50 counterclockwise, whereby the lower door part 20 moves somewhat downwards, until it is in the correct adjustment position parallel to the plane of the cabinet opening. In this operation the second pivot axis 27, with which the adjustment lever 25 and the adjustment element 30 are articulated with each other, remains stationary. By means of the washer-shaped drag element 42 in the form of a washer, an adjustment force is necessary, which exceeds the frictional force generated by the drag element 42. In this respect, the guide pin 41 with the washer configured as the element The friction drive 42 is guided in the guide housing as an oblong hole 39. In parallel, the fixing pin 47 configured as a screw is glided in the associated oblong hole 45. When the two door parts 19, 20 are located in The desired adjustment position has been reached parallel to the plane of the cabinet opening (figure 5). Then the furniture door 18 is reopened, not exceeding the force, which is applied for opening, the frictional force predetermined by the friction drag element 42, that is, the adjustment element 30 does not continue to rotate on the rotation axis 31. Therefore, the desired adjustment position is preset and does not vary when opening the furniture door 18. Then, after opening, the fixing pin 47 is tightened, whereby the support element 29 and the element adjustment 30 are fixed together without the possibility of rotation. Now, when a subsequent opening or closing is performed, only one pivot of the adjustment lever 25 takes place in the area of the second pivot axis 27, while the angular position of the support element 29 and the adjustment element no longer varies 30. The furniture door 18 is correctly adjusted, that is, the two door parts 19, 20 are located in the closed position in a coplanar manner with each other and parallel to the plane of the closet opening, the lower edge of the lower door portion 20 at the same height as the lower edge of the base wall 14.

The same adjustment effect can be achieved with the embodiment in which the support element 29 is supported by means of fixing holes as an oblong hole 35 on the rear side of the lower door part 20. In this case, by adjusting the lower door part 20 with respect to the support element, an adjustment can occur.

In principle, the door fastener 11 according to the invention can also be used for the adjustment of the two door parts 19, 20 with the furniture door 18 open.
