In order that, for example, a drawer can easily be moved into a closed position or moved out of such a position, such guide apparatuses are frequently equipped with pushing-out or retraction devices.

A closed position of the first furniture part is predefinable by way of the switching devices. Furthermore, connecting means for a coupled switching movement of the switching devices are provided between the guide devices. According to the present invention, in each case one carry-along element is provided on the guide devices and catching elements for the carry-along elements are present, wherein movements of the catching elements are coupled, wherein one carry-along element interacts with in each case with one catching element at least along one switching path of the switching device and wherein the carry-along elements are separated from the catching elements at least via a movement of the guide devices.
Description
- The invention relates to an apparatus for moving a first furniture part in relation to a second furniture part, and a piece of furniture having such an apparatus.
- A large number of apparatuses, by way of which furniture parts can be moved in relation to one another on a predefined track, are already known from the field of furniture construction. For example, many are provided for guiding the movement of drawers and similar pull-out furniture components on a basic furniture structure. In order that, for example, a drawer can easily be moved into a closed position or moved out of such a position, such guide apparatuses are frequently equipped with pushing-out or retraction devices. Because these usually also comprise a switching mechanism for locking a closed position, they are designated switching devices in the following text.
- Depending on the height/width ratios of a movable furniture part, for example of a drawer, there is a more or less great risk of the piece of furniture jamming in the guide devices, as a result of which movement can be hindered and a guide system may be damaged. For uniform distribution of driving and closing forces, such devices are preferably provided on two sides of movable furniture elements. For a uniform pull-out movement of opposite sides of, for example, a drawer, a plurality of racks attached, for example, to the base can be synchronized via toothed wheels, which are coupled to a common rotary shaft. However, such synchronization devices require a certain amount of installation space and possibly even occasional cleaning and maintenance.
- It is the object of the present invention to provide an apparatus which enables reliable opening and closing of a movable furniture part while having a comparatively small space requirement.
- The present invention proceeds from an apparatus for moving a first furniture part in relation to a second furniture part, wherein the apparatus has two spaced-apart guide devices in which switching devices are provided. A closed position of the furniture part is predefinable in this case by way of the switching devices. In addition, connecting means for a coupled switching movement of the switching device are provided between the guide devices.
- The core of the present invention consists in that in each case one carry-along element is provided on the guide devices, in that catching elements for the carry-along elements are present, wherein movements of the catching elements are coupled, wherein one carry-along element interacts with, in each case, one catching element at least along one switching path of the switching device and wherein the carry-along elements are separated from the catching elements at least via a movement, in particular a pull-out movement, of the guide devices.
- During the installation of guide devices, care is generally taken to ensure that, for example, left-hand-side and right-hand-side guide devices and the switching devices thereof are attached and set symmetrically. In use, forces can act asymmetrically on the furniture part and can lead to an offset between switching elements. The present invention is based on the finding that synchronization between switching devices, for example, of a left-hand and right-hand guide device of, for example, a drawer is in many cases necessary only in the region of the switching path of the switching devices, in particular for switching operations for locking and unlocking the closed position. In this case, it is sufficient for interaction between the carry-along elements and the catching elements to be limited substantially to the region of the switching path and for the synchronization elements, such as the carry-along elements and the coupled-together catching elements, to have no influence on movements of the furniture parts with respect to one another in the region of a pull-out movement away from the switching path.
- This affords the advantage that the first furniture part can be moved over a usually longer path of a pull-out movement without being influenced by synchronizing elements and thus without the frictional contribution thereof, while movements are coupled on both sides of interacting switching elements over a comparatively short switching path. Because a synchronizing coupling is provided substantially in the region of a switching path, the catching elements and the carry-along elements can be formed in a comparatively space-saving manner.
- The guide devices may comprise two or more rails and can be configured as, for example, a full-extension mechanism. The switching devices may be opening devices, in particular pushing-out devices, for example, touch-latch units. Furthermore it is possible for the switching devices to be closing devices, in particular automatic retraction units. In this case, the switching devices can support switching operations by way of which the first furniture part can be unlocked from a predefined closed position. Similarly, the first furniture part can be lockable in a predefined closed position of the switching operations by way of the switching devices.
- Preferably, the switching device is formed such that the switching path for a switching operation is comparatively short compared with the path of a pull-out movement. As a result, a comparatively compact construction of the carry-along and catching elements is advantageously possible.
- Bearing means for at least one of the catching elements preferably comprise an attachment element for attaching to a guide device, in particular on a switching device. This advantageously makes it easier to mount and adjust the apparatus according to the present invention.
- On account of manufacturing tolerances, by attaching the guide devices to the furniture parts it is also possible for the switching devices on both sides of a movable furniture part to be offset with respect to one another in relation to the movement direction of a pull-out movement. In order to be able to compensate for positional deviations, for example, with respect to movement-limiting stops, the switching devices preferably have one or more positionable parts. In order to transfer positional corrections to synchronizing elements, too, in particular to at least one of the catching elements, it is preferred for the attachment element to be fixable on a positionable part of the switching device. By way of the positionable part, a closed position can be set on the switching device. Furthermore, a positionable part can be used for adaptation to, for example, a switching path and, for example, to a switching position of the switching device.
- Since a housing, which is provided, for example, for protecting movable parts, is comparatively stable and usually provides a plurality of attachment positions, the positionable part of the switching device is preferably a housing, which surrounds in particular at least a part of the switching device.
- Furthermore, it is preferable for the attachment element to be attachable in a detachable manner. In this case, for example, a basic-furniture-structure rail may be provided for attaching the attachment element. In particular, the attachment element is attachable without tools, as a result of which subsequent installation of the catching elements is more easily possible.
- The catching element can have, for example, a lever, which can be folded over by a carry-along member. In a preferred embodiment of the present invention, the catching element comprises a rotary disk because a comparatively reliable and stable catching region for a carry-along element can be formed thereon.
- Preferably, a catching slot for the carry-along element is provided in the catching element, such that the carry-along element is producible and attachable in a comparatively simple manner, for example, as a hook or, for example, as a carry-along pin.
- In order that comparatively strongly offset movements of the carry-along elements between, for example, two sides can be synchronized, it is preferred for the catching slot to have in a catching position of the catching element, a section which extends parallel to the movement of the carry-along element. As a result, it can be ensured that, when a catching element is activated by a carry-along element, the carry-along element on the other side is likewise already located in the respective catching element.
- Preferably, first movement-limiting stops, by way of which a catching position of the catching element is predefined, are formed on the catching element and on the bearing means. In this case, the catching element may be subjected to a spring force which can hold the catching element in a catching position. Preferably, spring elements and the first movement-limiting stops are present on catching elements of a plurality of guide devices, for example, on both sides of, for example, a drawer, in order to increase the reliability of synchronization.
- Furthermore, it is preferred for at least one movement-limiting stop, by way of which a movement of the catching element is limitable when the carry-along element carries the catching elements during a switching movement, to be formed on the catching element and on the bearing means. As a result, in particular when the catching element is under spring force, it is possible to avoid the situation in which the carry-along element is able to leave the catching element in a position which makes it impossible for the carry-along element to be received in the catching element again.
- Preferably, a switching position of at least one of the switching devices is settable parallel to the traveling movement of the first furniture part. Likewise, it is preferred for a closed position and/or a switching path of at least one switching device to be settable parallel to the traveling movement of the first furniture part. As a result, the switching devices can be adapted to, for example, movement-limiting elements, for example, stops, and positional differences, for example, of the guide devices on account of manufacturing tolerances can advantageously be compensated.
- A piece of furniture having an apparatus according to the present invention in at least one of the abovementioned embodiments can be operated in a comparatively reliable manner and as a result advantageously increases the reliability in use.

Attached to the basic-furniture-structure rail 16 a is aswitching device 20 having ahousing 23 which is accessible through arecess 26 in the underside of the basic-furniture-structure rail 16 a. -
FIGS. 8 and 9 show only a view of an underside of the catchingunit 6 a, and so only apivot pin 15 and a mountingplate 14 of the catchingunit 6 a are discernible. Twobrackets 14 c located in a parallel direction in succession are punched out of the mountingplate 14, wherein thebrackets 14 c curve out towards the top side of the mounting plate. Thebrackets 14 c are provided to engage inslots 27 on the underside of the basic-furniture-structure rail 16 a, wherein thebrackets 14 c are formed such that they engage through theslots 27 and in the process can engage behind the basic-furniture-structure rail 16 a. - Formed on the mounting
plate 14 are twobars recess 26 on the underside of the basic-furniture-structure rail 16 a. Thebar 14 d is bent twice and at opposite angles at its end. As a result it is designed to engage behind therecess 26 in the basic-furniture-structure rail 16 a in order, for example, to prevent the mountingplate 14 from being removed from the basic-furniture-structure rail 16 a. - The
bar 14 b of the mountingplate 14 is provided to fix the mountingplate 14 to thehousing 23 of theswitching device 20. For this purpose, twostops 23 a are formed on thehousing 23. Thebar 14 b and thestops 23 a are matched to one another such that thebar 14 b can engage with negligible or no play between thestops 23 a. Thehousing 23 has a threadedsection 23 b. Ascrew cap 24 having an internal thread (not shown) is screwed onto the threadedsection 23 b. By way of ascrew cap 24, a position of thehousing 23 on the basic-furniture-structure rail 16 a is settable along the longitudinal axis of the housing in the attachment (not shown) thereof and parallel to the direction of movement of thedrawer rail 16 c. By engagement of thebar 14 b, settings of the position of thehousing 23 on the mountingplate 14 and thus on the catchingunit 6 a can be assigned. - A
coupling rod 28 is movably mounted in thehousing 23 and can be pushed out or retracted by an energy store, for example, a spring, accommodated, for example, in thehousing 23. A switching mechanism (not shown), which predefines, for example, a closed position or switching position, can be accommodated in the housing. As a result of the engagement of thebar 14 b in thehousing 23, the position of the catchingunit 6 a is coupled directly to the respective position of the closed position or switching position. -
