This application claims foreign priority under 35 U.S.C. ยง119(a)-(d) to German Application No. 20 2015 006 278.4 filed on Sep. 4, 2015, the entire contents of which are hereby incorporated by reference.
The invention relates to a guide device for guiding a furniture pull-out, which can be moved in relation to a furniture body, said guide device comprising at least one guide unit, which has a body rail, which can be fastened to the furniture body, and at least one running rail, which is displaceably mounted relative to the body rail, and comprising a functional device, which comprises at least a first functional element, which can be fastened to the moveable furniture pull-out, and at least one body-sided second functional element, both functional elements being guided on one another during the retraction movement and/or the extension movement of the furniture pull-out.
Guide devices for guiding a furniture pull-out, which can be moved in relation to a furniture body, for example, pull-out guides for drawers, have already been known for a long time. Furthermore, it is known to equip such guide devices with functional devices, for example, with a self-retracting device, by means of which the moveable piece of furniture, in particular, the drawer, after a certain closing travel of the drawer, retracts automatically or in a power-assisted manner into the closed position.
In addition, it is known to provide guide devices with functional devices in the form of a damping device, by which it is possible to damp the retraction and/or extension movement of the moveable piece of furniture into the closing and/or opening position. Furthermore, it is known to provide adjustment devices, with which the position of the moveable piece of furniture with respect to the guide device can be changed. Such adjustment devices include, in particular, side, depth, height and/or tilt adjustment devices.
Usually several of the aforementioned functional devices are combined with each other. In this case the task of keeping the functional devices functionally effective during the side, depth and/or height adjustment of the moveable piece of furniture with respect to the guide device is often a problem, if said functional devices consist of components, which are moved on the furniture pull-out and, therefore, are moved with it at the same time, and stationary components, since the moveable piece of furniture will jump off the converging track of the components as a result of the adjustment.
Therefore, the object of the present invention is to provide a guide device of the type, described in the introductory part of the specification, in such a way that the functional devices, which are arranged on the guide device, are reliably effective, even in the event that the position of the associated moveable piece of furniture is adjusted.
The guide device of the invention is characterized by the feature that it has a catch device, which has a bearing mechanism, by means of which the first or second functional element can be moveably hung, and a control surface, which is formed on the first and/or second functional element and by means of which the moveable first functional element can be captured in order to subsequently guide on the second functional element. As a result, the catch device makes it possible to guarantee that the functional device is functionally effective, even if the moveable piece of furniture is adjusted in its position, for example, in relation to the guide device, for example, by carrying out a side adjustment and/or a tilt adjustment of the moveable piece of furniture with respect to the guide device. Thus, the catch device makes sure that the component of the functional device that is disposed on the moveable piece of furniture comes into contact with the component, which is disposed on the guide device, in such a way that the functional device is functionally effective.
In a further development of the invention the pull-out-sided first functional element can be suspended from the furniture pull-out by means of the bearing mechanism in a manner allowing movement relative to the furniture pull-out, and the body-sided second functional element can be fastened stationarily relative to the furniture body via a mounting mechanism. Therefore, it is useful for one of the functional elements to be hung rigidly and the other to be hung moveably. Preferably the pull-out-sided first functional element is hung moveably, while the body-sided second functional element is fastened rigidly. As an alternative, however, it is also conceivable to fasten the pull-out-sided first functional element rigidly to the furniture pull-out and to fasten the body-sided second functional element moveably to the furniture body.
In a particularly preferred manner the control surface is formed on the body-sided second functional element. Therefore, the second body-sided functional element can provide a constraining guide for the pull-out-sided first functional element.
It is possible that the control surface has an inclined section that extends at an angle in relation to the direction of movement of the furniture pull-out. This arrangement makes it easier to move the pull-out-sided first functional element, which is moved at the same time that the furniture pull-out is moved, into the constraining guide of the second functional element.
It is particularly preferred that the second functional element has a control element, which is designed, in particular, in the manner of a web having a bottom side, on which the control surface is formed. It is particularly preferred that the inclined section of the control surface is located on the control element, and that preferably the second functional element has a check surface that is located opposite the control surface and that forms together with the control surface a kind of guide channel in order to guide the pull-out-sided first guide element. The check surface may also have an inclined section that forms together with the inclined section of the control surface a kind of retraction funnel.
In a further development of the invention the body-sided second functional element has a mounting interface for fastening, in particular, without a tool to the furniture body or to a mounting angle bracket, which can be fastened to the furniture body, or to a mounting section of the body rail.
For a further development of the invention the second functional element is designed as a flat body, in particular, in the manner of a plate.
It is possible that the body-sided second functional element has at least one fastening interface for fastening accessory parts thereto. Then at least one accessory part can be fastened in a fast and easy way to the body-sided second functional element via the at least one fastening interface. It is expedient for the accessory carrier to have a plurality of fastening interfaces, so that it is possible to fasten a plurality of accessory parts to said accessory carrier. If there is a plurality of fastening interfaces, then it is possible to populate all of the fastening interfaces with accessory parts or, depending on the specific requirements, only the respective fastening interface that is required for the associated accessory part.
In a further development of the invention the pull-out-sided first functional element has a base section, which can be rigidly fastened to the furniture pull-out, and a movement section, which is moveably hung in relation to the base section, where in this case the movement section can be moved between a starting position and functional positions, which are, in particular, farther away from the base section. In principle, the movement section can occupy any functional position between the starting position and an end position, which is defined by the maximum stroke between the base section and the movement section.
It is possible that the bearing mechanism have at least one spring element having a spring force that acts on the movement section in the direction of the starting position. It is expedient for the movement section to have a guide section, which is assigned to the control surface and which is guided on the control surface.
In a further development of the invention the bearing mechanism is designed to hang the movement section in a manner allowing a swiveling motion in relation to the base section.
In a particularly preferred manner the bearing mechanism has a hinge that is effective between the base section and the movement section.
It is possible that the bearing mechanism is designed for a linearly moveable suspension of the movement section in relation to the base section.
In a further development of the invention the functional device is designed as a damping device in order to damp the opening movement of the moveable piece of furniture. Preferably in this case a clamping roller is provided on one of the functional elements, in particular, on the first functional element, and a clamping wedge, which interacts with the clamping roller, is provided on the other one of the functional elements, in particular, on the second functional element. The result of this arrangement is a kind of mechanical brake, which checks the outward extension movement of the furniture pull-out into the open position. It goes without saying that it is also possible to employ the functional devices in a different way. For example, the damping device could also be used to damp the closing movement of the furniture pull-out. Furthermore, it is possible to design the functional device as a self-retracting device.
Preferred exemplary embodiments of the invention are shown in the drawings and are explained in greater detail below. The drawings show in:
The drawer is displaceably mounted in relation to a furniture body (not depicted) by means of the guide device 11. The guide device 11 comprises a plurality of guide units 13, of which two guide units 13 are assigned to the side edges of the drawer that are opposite each other. In the drawing a single guide unit 13 is shown only in schematic form, but the other guide unit, which is assigned to the opposite side edge of the drawer, is constructed in the same way.
Each of the guide units 13 has a body rail 14, which can be configured, for example, as a bent-over sheet metal component. The body rail 14 is fastened via a suitable fastener to an associated side wall of a drawer holder, which is designed in the furniture body, in such a way that said body rail is fixed in position. A central rail (not depicted) is displaceably mounted on the body rail 14, and on this central rail in turn a pull-out rail or running rail is displaceably guided by a bearing mechanism. The pull-out rail is assigned to the drawer and extends below the drawer bottom 15 in the depth direction. The combination of body rail 14, central rail and pull-out rail is called full extension. However, it is also conceivable to use the guide units 13 without the central rail.
As shown, in particular, in
As shown in schematic form in
Furthermore, the guide device 11 comprises a functional device 22, which has at least a first functional element 23, which can be fastened to the drawer, and at least one body-sided second functional element 24, where both first and second functional elements are guided on one another during the inward retraction and/or outward extension movement of the furniture pull-out.
In the case of the example the functional device 22 is designed as a damping device for damping the opening movement of the drawer. As shown, in particular, in
The clamping roller 25 and the clamping wedge 26 form a mechanical damping device in the manner of a brake. In the course of moving inwards, the clamping roller 25 is wedged at the clamping wedge 26 as a result of the tapering clamping gap 27. This arrangement makes sure that the outward extension movement of the drawer into the opening position is slowed down and, as a result, is damped.
Hence, in order to guarantee the function of the functional device 22, which is designed as a damping device, there is the requirement that the clamping roller 25 must come into engagement with the clamping wedge 26. Therefore, it is necessary that the pull-out-sided first functional element 23, which is moved at the same time that the drawer moves, comes into engagement with the body-sided second functional element 24 in such a way that the clamping roller 25 and the clamping wedge 26 are effective.
Therefore, the functional device 22 has a catch device 28, which has a bearing mechanism, by means of which the first or second functional element 23, 24 can be hung in a manner allowing movement, and has a control surface 29, which is formed on the first and/or second functional element 23, 24, and this control surface is used to capture the moveable first functional element 23, in order to subsequently guide the second functional element 24.

As shown, in particular, in
Furthermore, the first functional element 23 has a movement section 32, which is hung in a manner allowing movement in relation to the base section 29. The movement section is also designed in the manner of a plate and is arranged at a distance opposite the base section 29.
As shown, in particular, in
Furthermore, the hinge 33 has two hinge legs 35, which are arranged on the base section 29 on opposite transverse sides and which project away from the base section 29. These hinge legs plunge into corresponding hinge retainers 36, which are disposed on the two opposite transverse sides on the movement section 32 and which open in the direction of the base section 29. When the movement section 32 is swiveled about the hinge axis 34 in relation to the base section 29, the legs 35 move a little way out of the associated hinge retainers.
As shown, furthermore, in
It is expedient for there to be two tension springs 37, of which the one is assigned to the transverse side and the other is assigned to the other transverse side of the first functional element 23. The tension springs 37 can be separate parts with respect to the base section 29 and the movement section 32. These tension springs can be fastened, on the one hand, to the base section 29 and, on the other hand, to the movement section 32 in such a way that they can be disconnected. For example, these tension springs can be clipped into retainers, which are provided for this purpose. It is possible that the tension springs 37 are made of the material of the first functional element 23, which is made of a synthetic plastic material. However, as an alternative, it is also possible to make the tension springs 37 of other materials, for example, a metal material.

The mounting angle bracket 41 has a functional leg 44, which projects at an angle, in particular, at right angles from the mounting leg 42 and to which the second functional element 24 can be fastened. The second body-sided functional element 24 is designed as a flat body, for example, in the form of a carrier plate. The second functional element 24, which can also be referred to as the accessory carrier, is made expediently of a synthetic plastic material.
On a top side 45 of the second functional element 24 there is a mounting interface 45 for mounting the second functional element 24 on the functional leg 44 of the mounting angle bracket 41. The mounting interface 45 has first and second holders 46a, 46b, which overlap the functional leg 44 of the mounting angle bracket 41 in the mounted state of the second functional element 24.
The second functional element 24 has a slot 47, which extends transversely to its longitudinal extent and which is open towards a longitudinal side of the second functional element 24.
The slot 47 divides the second functional element 24 into a first and a second carrier part 48a, 48b. The two carrier parts 48a, 48b can be moved relative to each other in such a way that the distance between the two holders 46a, 46b for mounting the second functional element 24 on the associated functional leg 44 can be enlarged with simultaneous widening of the slot 47. The two carrier parts 48a, 48b are connected together via a solid hinged joint 49 at the base of the slot 47 in such a way that they can be moved. In addition, the rear section is designed to be springy/resilient.
