Description

State of the art

In furniture with a movably received on a furniture carcass furniture part, wherein by means of a drive assembly with spaced motion elements, a drive movement is transmitted to corresponding components, devices for stabilizing the overall arrangement and / or synchronization of the drive movement are known. For example, in furniture with pull-outs or drawers, these are moved relative to the carcass via a guide device with guide rails which interact with one another in a displaceable manner. The guide device has two spaced apart and identically constructed guide units, which each interact with a transmission element to drive the guide units similar.

With the arrangements mentioned, unwanted noises and / or uncontrolled component movements regularly occur in the region of the connection of the movement elements.

Purpose and advantages of the invention

Object of the present invention is a piece of furniture and a To improve technically and economically on a furniture of the type mentioned in the introduction.

This object is solved by the independent claims.

The dependent claims are directed to advantageous developments of the invention.

The invention relates to a device on a furniture with a first furniture part which is movable relative to a second furniture part and spaced movement elements, which are provided at opposite locations on the first furniture part comprises, wherein the movement elements via a connecting shaft of the device, the is added to the movement elements are synchronized with each other. In particular rotatable gear elements are connected to the connecting shaft, which each act on similar guide units of a furniture part guide for applying a drive effect of a drive unit. The Bewegungselsmente serve in particular for a movement of the first furniture part, such as a drawer or an excerpt from the second furniture part or a body out and back into the body, for example, with a Ausschiebe- or insertion movement, for which the furniture part guide between the Carcass and the first furniture part is arranged.

The essence of the invention is the separate bearing means for supporting the connecting shaft between the moving elements are present. This is particularly advantageous in view of hitherto regularly occurring vibration or impact noise of the connecting shaft, which can be avoided with the separate bearing.

So far, the connecting shaft is mounted solely on the movement or transmission elements, which, however, makes it possible with appropriate larger dimensions of the furniture or the distance between the guide units and thus between the movement elements, no balanced storage of the connecting shaft. With larger by the connecting shaft to span spanning distance of the moving elements, for example, more and more users of desired very wide driven movable drawers, it can come in the rotary operation of the connecting shaft in particular at corresponding resonance speeds to vibrations, vibrations or imbalance or deflection movements of the connecting shaft. In addition, with space-saving design, the connecting shaft is only slightly spaced from adjacent component sections, so that it can come regularly without contact inventive arrangement for contact of the connecting shaft with these component sections. This causes unwanted impact noise and leads to damage to the relevant components.

The separate storage means are in particular designed as a separate unit and, depending on where the movement elements are present, on the first furniture part, for. B. on a rear wall of a drawer, or the second furniture part, for example on a rear wall of a furniture body, attach or remove again. This can be done in particular with a few simple steps and / or without tools. At the separate storage means, the connecting shaft can also be attached or removed with a few simple steps or without use of tools.

The connecting shaft, which has hitherto been mounted exclusively via the movement elements or gear elements, now receives an additional bearing point via the separate bearing means, which is positioned over the length of the connecting shaft, in particular in the central region between the spaced movement elements.

The connecting shaft is otherwise free or spaced apart from sections of the furniture, which is advantageous for assembly and disassembly. With regard to the total length of the connecting shaft, the separate bearing means take in particular only a comparatively short section in the longitudinal direction of the connecting shaft.

In the case of drawers, for example, two similar guide units, which are present on opposite longitudinal sides of the drawer, are usually used, each with guide rails which can be displaced relative to one another. When moving the furniture part, the guide rails of a guide unit telescope each other, whereby the movable furniture parts can be moved relative to the body and moved into it. Both guide units are usually driven by at least one moving element in each case. By way of example, a driven gear pinion is connected via the connecting shaft to a corresponding gear pinion present in the opposite direction on the further guide unit and moved in a rotational manner. The movement elements can be driven via a drive unit, for example via an electric motor, and interact with a counterpart section on the guide unit for drive transmission. In general, a direct drive only takes place on a guide unit or directly on only one of the cooperating movement elements, so that the movement elements are rotationally connected to the connecting shaft and a drive force is transmitted to the movement element not driven directly by the drive unit.

The rotational movement transmission between the connecting shaft and the moving elements can take place via tooth profile sections which are present on the connecting shaft at the end or on the outside, when the movement or gear elements are designed as toothed wheels or pinions. But there are also other types of transmission feasible.

Further, it is advantageous that the bearing means are designed to store the connecting shaft in the region of a separation point of the connecting shaft. The separation point refers to a separation of the connecting shaft in the longitudinal direction. Thus, advantageously, a connecting shaft can be used, which, viewed in the longitudinal direction, comprises two or more sections, each corresponding to the total length of the

Pieces assembled connecting shaft are shorter. This is particularly advantageous for transport reasons and for easier assembly and disassembly of the connecting shaft.

In the case of more than one separation point of the connecting shaft, that is to say for more than two sections of the connecting shaft, the separate bearing means comprise more than one bearing point or, per separating point, a bearing unit, wherein in particular each bearing unit can be attached to the first or second furniture part as a separate structural unit. The several bearing units are in particular all identical or identical in construction. Since the sections of the connecting shaft are usually constructed identical, overall, the assembly of the connecting shaft sections with the storage units can be uncomplicated go.

In particular, it is advantageous that the bearing means are adapted to support opposite ends of the connecting shaft, which are present at the separation point of the connecting shaft. Thus, the individual can be at least two sections or partial waves not only stored in the assembled state of the connecting shaft and the bearing means at the separation point of the connecting shaft but also connected to each other. The bearing means therefore preferably comprise connection means for connection of opposite ends of portions of the separate connection shaft.

It is further proposed that the bearing means have a bearing base body with a receiving contour for an aligned receiving the ends at the separation point of the connecting shaft. The assembled bearing body specifies the position of the bearing, with the bearing base body at the same time an aligned arrangement of the partial waves to be mounted is realized. The receiving contour may be a matched to the dimension or shape of the connecting shaft through hole in the bearing body.

In or on the bearing body can advantageously the Connecting means for the connection of opposite ends of the sections of the separate connecting shaft to be stored in stock. For structural reasons and in view of a small number of components of the separate bearing means, the separate bearing means comprise exactly one connecting piece for connecting two ends of two partial shafts at a separation point of the connecting shaft. The connector can be easily inserted in the body and removed again.

In an advantageous modification of the subject invention, a coupling element for a detachable connection of ends to be joined together is provided at the separation point of the connecting shaft. The coupling element serves in particular as a connection means of the separate part waves and is in particular designed so that it can tuned to the respective ends of the sections to be connected to the respective bearing point of the connecting shaft with these ends set a solid but detachable connection, for example, a plug, clamp -, snap, snap or clip connection. In particular, twisting of the sections of the connecting shaft relative to the coupling element is prevented with the connection. As a rule, both ends to be joined together are similar at the point of separation of the connecting shaft, so that two similar sections are formed on the coupling element for connection to the ends at the separating point.

Advantageously, the coupling element is rotatably received in the bearing body of the bearing means. Thus, a stable and functionally reliable arrangement of the bearing means is realized.

Preferably, the coupling element is captively received in the bearing body. With the protection against loosening of the coupling element from the bearing main body, the connecting shaft is securely held at the bearing point for permanent operation in the assembled state of the connecting shaft to the coupling element and the bearing body.

Advantageously, the coupling element is received in the bearing main body with a bearing clearance transverse to a rotational axis of the rotational movement of the coupling element. With the bearing clearance dimensional deviations or tolerances of relevant components such. B. the sections of the connecting shaft, the moving elements or other components are compensated. In particular, the separate bearing means thus provide a bearing point which allows compensating movements in two directions transversely to the axis of rotation of the connecting shaft. This makes it possible to avoid or at least minimize noise in the rotary operation of the connecting shaft and / or malfunctions due to an unfavorable combination of component dimensions.

Furthermore, the invention relates to a piece of furniture with a first furniture part, which is movable relative to a second furniture part and spaced apart movement elements, which are present at opposite locations on a furniture part comprises, wherein the movement elements are synchronized with each other. Advantageously, one of the aforementioned devices is present. Thus, the advantages explained above can be realized on a piece of furniture.

Preferably, the connecting shaft is received via the movement elements and the bearing means and otherwise extends freely on the first or second furniture part. Thus, the assembly and disassembly of the connecting shaft can be easily made. Advantageously, the furniture part itself need not be specifically designed for the presence of the connecting shaft or may be designed as in furniture that have no drive assembly so no movement elements and no connecting shaft.

According to a further advantageous embodiment of the subject invention, the connecting shaft viewed in the longitudinal direction exactly on a separation point between two shaft sections of the connecting shaft, wherein the separation point viewed in the longitudinal direction of the connecting shaft in a central portion between the moving elements is trained. Thus, a certain symmetry of the arrangement of the connecting shaft can be realized, which is advantageous technically and with respect to an appearance of the furniture.

Finally, it is further proposed that the bearing means are provided on an upper narrow side of a rear wall of the furniture part, on a rear outer side of the rear wall of the furniture part and / or on the furniture body. This is advantageous in terms of flexibly settable and space-saving attachment of the connecting shaft.

For the connecting shaft can extend above the narrow side of the rear wall of the furniture part or outside of the rear wall when the connecting shaft is present on the furniture part, so that the storage means are present in accordance with these areas. If the connecting shaft is installed on the furniture carcass, the connecting shaft or, thus, the bearing means can be fastened to a rear wall or another section of the carcass.
