Description

Background Art

[0001] Devices for controlling the movement of two guide rails of a furniture part are known. The device controls two guide rails, for example two partially telescopic rails or two fully telescopic rails. The movement control device is used, for example, to cause a force-assisted and / or damped movement of the corresponding movement rails of two partially telescopic or fully telescopic rails. Accordingly, the movement of the furniture part relative to the furniture body, to which the furniture part is mounted via the two guide rails, is influenced. Such a furniture part is, for example, a furniture part capable of linear movement, such as a drawer, which is movably received on the furniture body via two identical guide rails. Summary of the invention

[0002] The object of the present invention is to provide an alternative for the movement control of two guide rails in the furniture sector, in particular to provide a device for the movement control of two guide rails which is improved with regard to assembly and / or mounting on a furniture part.

[0003] This object is achieved by the independent claim. The dependent claims present practical and advantageous further developments of the invention.

[0004] The present invention relates to a device for controlling the movement of two guide units, wherein the two guide units respectively include a fixed rail and a movable rail that can move relative to the fixed rail, wherein the device includes a first ejection unit and a second ejection unit, the first ejection unit and the second ejection unit can be respectively arranged on the corresponding guide units and spaced apart from each other, wherein a synchronizer with a connecting element is provided, wherein the connecting element is a separate component, and the connecting element connects the first ejection unit and the second ejection unit to each other so as to synchronize the two ejection units, wherein the two ejection units are constructed identically, wherein each ejection unit respectively has an adapter mechanism, and the corresponding end section of the connecting element can be releasably mounted on the adapter mechanism.

[0005] The connecting element is configured as a synchronization rod, for example. For example, the maximum outer diameter of the connecting element is smaller than, for example, an average outer diameter of the adapter means or smaller than, for example, a maximum outer diameter of the adapter means.

[0006] The adapter mechanism is received on the ejection unit so as to be rotatable, for example, in two possible directions of rotation. For example, the axis of rotation of the adapter mechanism is oriented transversely to the linear movement direction of the slide relative to the base component.

[0007] For example, the ejection unit for the furniture part is designed to act synchronously, for example additionally as a drawer opening device.

[0008] The ejection unit comprises, for example, an adapter element, a base component, a slide, an energy storage device, a locking mechanism, a heart-shaped cam and a ratchet mechanism.

[0009] The basic component comprises, for example, a connection housing, which can be connected, for example, detachably, to the remaining basic component. The connection housing comprises, for example, a mounting section for the adapter mechanism. For example, the locking mechanism is received, for example, supported on the connection housing. For example, the bent wire component is received on the connection housing or on the remaining basic component. The wire component comprises, for example, a locking mechanism, for example, as a bent end of the wire component. For example, the other bent end of the wire component is fixedly, but for example detachably, mounted on a bearing point on the basic component.

[0010] The locking mechanism is configured, for example, as an end section of a wire member. The locking mechanism is configured, for example, as a section of an elastically deformable wire element. The locking mechanism is configured, for example, as a section of a wire element, wherein the wire element comprises a straight section and a curved section, which are connected to each other, for example, in one piece.

[0011] For example, the position of the connecting housing relative to the basic component is adjustable. For example, the position of the connecting housing relative to the basic component can be adjusted in a closing direction and / or in an opening direction. For example, the position of the connecting housing relative to the basic component can be adjusted steplessly, for example, in a closing direction and / or in an opening direction. For example, the position of the connecting housing relative to the basic component can be adjusted manually or without tools, for example, by rotating a knurled screw, which is, for example, rotatably received on the basic component.

[0012] The guide unit configured as a partially telescopic slide rail comprises a fixed rail that can be connected to a furniture body and a movable rail that can be coupled to a furniture part. For example, the fixed rail and the movable rail can be telescopically movable relative to each other.

[0013] In the fully telescopic slide rail, there is an intermediate rail between the fixed rail and the moving rail. For example, the fixed rail, the intermediate rail and the moving rail can be telescopically movable relative to each other.

[0014] Typically, the rails of a guide unit, ie a partially telescopic rail or a fully telescopic rail, are movable relative to each other via a bearing assembly, for example comprising rolling bearing arrangements, such as ball and / or roller bearing elements. The bearing assembly acts between adjacent rails of the guide unit.

[0015] For example, in furniture with a relatively large front, such as a relatively wide drawer, the drawer is guided on the furniture body by two guide units and the drawer is opened by a touch lock function, for example a synchronous touch lock trigger is provided. Thus, the locked position of the device can be cancelled by moving the slide in the closing direction.

[0016] The core of the present invention is that the adapter mechanism provides a receiving section with a receiving cavity, and the end section of the connecting element can be fixedly arranged in the receiving cavity relative to the adapter mechanism, wherein the receiving cavity with respect to the installed end section of the connecting element is surrounded by a fixed wall of the adapter mechanism on a partial circumference relative to the longitudinal axis of the end section of the connecting element, and there is a locking section of the adapter mechanism on the remaining circumferential section relative to the partial circumference, wherein the installed end section of the connecting element is in contact with the fixed wall, wherein the locking section can be pivotally hinged on the adapter mechanism and can be reversibly pivoted from an open position of the locking section on the adapter mechanism to a fixed closed position of the locking section, in which the receiving cavity is open on the remaining circumferential section to insert the end section of the connecting element, wherein in the closed position of the locking section, the remaining circumferential section is closed.

[0017] This is a solution that is easy to assemble. Previously, for example, an axial screw connection of the end section of the connecting element with the corresponding ejection unit had to be carried out disadvantageously or under difficult assembly conditions.

[0018] The movable rail that can be coupled with the furniture part can be linearly moved relative to the fixed rail, for example, along the opening direction and along the closing direction. For example, the device is configured to force-assistedly move the movable rail from the closed position of the movable rail along the opening direction in a state arranged on the guide unit.

[0019] A corresponding ejection unit comprises, for example, an energy storage device, a base component and a slide movable relative to the base component, wherein the slide can be moved in an opening direction under the action of the charged energy storage device and drives the sliding rail in the opening direction when the device is mounted on the guide unit.

[0020] The device comprises, for example, a locking assembly with a heart-shaped cam-slot guide and a locking mechanism that can be contacted along the heart-shaped cam. For example, when the energy accumulator is loaded in the locking position of the device, the slide assumes a locking position, wherein the movement of the slide in the opening direction is blocked.

[0021] For example, the connecting element connects two slides of two devices to one another in such a way that a locked position of the slide of one ejection unit and a locked position of the slide of the other ejection unit are synchronously released.

[0022] For example, the linear movement of the slide and the rotational movement of the connecting element about its longitudinal axis are mechanically coupled by means of the connecting element. For example, the slide and the transmission profile are fixedly or rigidly connected to each other, for example integrally, for example formed on the slide component. For example, the transmission profile of the slide can be moved linearly, for example can be moved linearly back and forth together with the rest of the slide, for example can be displaced or shifted. For example, the linear movement of the slide is temporarily coupled to the linear movement of the furniture part.

[0023] For example, the adapter mechanism is constructed in one piece. This enables advantageous production of the adapter mechanism. For example, the adapter mechanism is made of a plastic material. The adapter mechanism is, for example, a plastic injection molded part. For example, the adapter mechanism is alternatively made of a metal material.

[0024] For example, the locking section of the adapter mechanism is connected to the rest of the adapter mechanism via a film hinge. The film hinge can be easily manufactured. For example, the film hinge is designed integrally with the locking section and the rest of the adapter mechanism. The film hinge is durable or strong. For example, the mobility, for example the flexibility, of the film hinge can be influenced by a predetermined thickness of the material forming the film hinge and / or the material properties of the plastic forming the film hinge. For example, the preload force of the closed film hinge in the closed position can also be predetermined thereby.

[0025] The adapter mechanism has, for example, a latching element, by means of which the locking section can be fixed in its closed position. For example, a section of the latching element is located on the locking section, and another part of the latching element is located on a matching section on the remaining part of the adapter mechanism. For example, by moving the locking section, the latching element can be brought into the closed position in the direction of the other part of the latching element. For example, the locking section can latch itself in the closed position. For example, the latching element can be released manually from the latching position.

[0026] For example, in the closed position of the locking section, the locking section can be hooked on the adapter mechanism by means of a latching member. For example, a partial region of the latching member can be elastically movable, for example deflected.

[0027] For example, the latching element is designed to form a snap-on connection. For example, the latching element comprises an undercut on the latching section and / or an undercut on the remainder of the adapter means. For example, the latching element has a toothed section which is fixedly held in the connection position, for example snaps back on the latching edge. For example, the fixed holding is based on a restoring force which is provided by the elastic properties of the film hinge and / or by a partial area of ​​the latching element.

[0028] For example, the outer shape of the end section of the connecting element and the inner shape of the receiving section are configured to match each other. Thus, for example, a reliable connection between the end section of the connecting element and the adapter mechanism is achieved by surface compression of sections that can contact each other.

[0029] For example, the outer shape of the end section of the connecting element and the inner shape of the receiving section are configured such that in the closed position of the locking section a positive connection is produced between the end section of the connecting element and the adapter means. The outer shape of the end section of the connecting element comprises, for example, an outwardly curved section, wherein the outwardly curved section and the recessed configuration of the inner shape of the receiving section are matched to each other in such a way that the end section of the connecting element and the inner shape of the receiving section, for example, the fixing wall of the inner shape, contact each other in an exactly matching manner, for example, without play or with a relatively small play, for example, almost without play.

[0030] For example, there is a toothed profile section of the adapter means, wherein the toothed profile section is designed to be axially offset from the receiving section. The axial offset is relative to the longitudinal axis of the plug-connected connecting element. For example, the toothed profile section is designed as a pinion section, for example, the toothed profile section is designed as a regularly configured external toothed profile. For example, the maximum outer diameter of the toothed profile section is equal to or smaller than the outer diameter of the adapter means in the region of the receiving section.

[0031] For example, the two adapter mechanisms on the corresponding ejection units are constructed identically. This is easy to assemble and economically advantageous. For example, the two adapter mechanisms are completely identical.

[0032] For example, the end sections of the connecting element are cylindrical in basic shape on the outside and have a fitting contour extending in the longitudinal direction of the connecting element. For example, the connecting element has a uniform shape over its entire extension or over its total length including the two end sections and the remaining section located therebetween. As a result, the initial component forming the connecting element can be cut to any desired length.

[0033] For example, the engagement contour is designed to protrude linearly outwards on a basic shape of the connecting element, wherein the basic shape of the connecting element is, for example, cylindrical or cylindrical.

[0034] For example, the fitting contour has two diametrically opposed projections relative to the longitudinal axis.For example, the projections are realized relative to the outer basic shape of the connecting element, which is, for example, cylindrical.

[0035] The mating contour comprises, for example, two radially opposite, parallel, outwardly protruding projections on the outside, which are, for example, convex or protrude outwardly.

[0036] For example, two opposite projections are designed identically, for example, are designed continuously in the longitudinal direction on the connecting element.

[0037] The locking section, for example, has a contact contour that can contact the connecting element, which is matched to the outer contour of the connecting element to make a mating contact in the closed position of the locking section. Thus, the connecting element can be connected to the adapter mechanism in a rotationally fixed manner.

[0038] For example, a guide rail is proposed which comprises two guide units which each have a fixed rail which can be connected to a furniture carcass and a movable rail which can be coupled to a furniture part, wherein a device according to one of the above-described embodiments is present.

[0039] For example, a piece of furniture is proposed, which has a furniture body and a movable furniture part, wherein a guide rail as described above is arranged. BRIEF DESCRIPTION OF THE DRAWINGS
