Description

BACKGROUND

[0001] Devices for the movement control of two guide rails of a furniture part are known. The devices control two guide rails, for example two part telescopic slide rails or two full telescopic slide rails. The movement control devices are used, for example, for force-assisted and / or damped movement of the respective moving rail of two part telescopic or full telescopic slide rails. The movement of the furniture part relative to the furniture body, on which the furniture part is mounted by means of the two guide rails, is influenced accordingly. Such a furniture part is, for example, a linearly movable furniture part, for example a drawer, which is movably received on a furniture body by means of two identical guide rails. SUMMARY

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

[0003] This task is solved by the independent claims. The dependent claims propose further expedient and advantageous embodiments of the invention.

[0004] The invention relates to a device for the movement control of two guide units, wherein the two guide units each comprise a fixed rail and a moving rail which is movable relative to the fixed rail, wherein the device comprises a first and a second push-out unit, which can each be arranged on the respective guide unit and are spaced apart from one another, wherein a synchronizer with a connecting element is provided, wherein the connecting element connects the first and the second push-out unit to one another in order to synchronize the two push-out units, wherein the two push-out units are identically configured, wherein each push-out unit has an adapter mechanism on which a respective end section of the connecting element can be releasably mounted.

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

[0006] The adapter mechanism is received, for example, rotatably on the push-out unit in two possible rotational directions. For example, the rotational axis of the adapter mechanism is oriented transversely to the linear movement direction of the carriage relative to the base member.

[0007] For example, the push-out units for a furniture part are configured synchronously, for example additionally as a drawer opening device.

[0008] The push-out unit comprises, for example, an adapter element, a basic component, a slide, an energy store, a locking mechanism, a heart-shaped cam and a ratchet mechanism.

[0009] The basic component comprises, for example, a connection housing which can be, for example, releasably connected with the remaining basic component. The connection housing comprises, for example, a mounting section for the adapter mechanism. The locking mechanism is received, for example, supported on the connection housing. The curved wire component is received, for example, on the connection housing or on the remaining basic component. The wire component comprises, for example, the locking mechanism, for example as one curved end of the wire component. The other curved end of the wire component is fixedly, however, for example, releasably mounted on a support site on the basic component.

[0010] The locking mechanism is configured, for example, as an end section of the wire component. 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, integrally.

[0011] The position of the connection housing relative to the basic component is adjustable, for example. The position of the connection housing relative to the basic component can be adjustable along the closing direction and / or along the opening direction, for example. The position of the connection housing relative to the basic component can be steplessly adjustable, for example, along the closing direction and / or along the opening direction. The position of the connection housing relative to the basic component can be adjustable manually or tool-free, for example, by rotating a knurled screw which is received, for example, rotatably on the basic component.

[0012] The guide unit configured as a partial telescopic slide rail comprises a stationary rail connectable with the furniture body and a moving rail couplable with the furniture part. The stationary rail and the moving rail are relatively movable telescopically, for example.

[0013] In a full telescopic slide rail, there is an intermediate rail between the stationary rail and the moving rail. The stationary rail, the intermediate rail and the moving rail are relatively movable telescopically, for example.

[0014] Generally, the rails of the guide unit, i.e. of the partial telescopic slide rail or of the full telescopic slide rail, are movable relative to each other by means of a bearing assembly, for example comprising rolling bearing means, for example ball and / or roller bearing elements. The bearing assembly acts between adjacent rails of the guide unit.

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

[0016] The core of the invention is that the adapter mechanism provides a receiving section with a receiving cavity in which the end section of the connecting element can be position-fixedly arranged, wherein the receiving cavity with respect to the mounted end section of the connecting element is surrounded by a fixed wall of the adapter mechanism on a partial circumference with respect 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 with respect to the partial circumference, wherein the mounted end section of the connecting element is in contact with the fixed wall, wherein the locking section is swingably hinged on the adapter mechanism and can be reversibly swung from an open position of the locking section on the adapter mechanism, in which the receiving cavity is open on the remaining circumferential section for the insertion of the end section of the connecting element, to a fixed closed position of the locking section, in which the remaining circumferential section is closed.

[0017] This is an easy-to-assemble solution. Previously, the axial screw connection of the end section of the connecting element with the respective push-out unit had to be made disadvantageously or under difficult assembly conditions.

[0018] The mobile rail, which can be coupled with the furniture part, can be linearly moved with respect to the fixed rail, for example along the opening direction and along the closing direction. For example, the device in the state arranged on the guide unit is configured for force-assisted movement of the mobile rail from the closed position of the mobile rail along the opening direction.

[0019] The respective push-out unit comprises for example an accumulator, a base member and a carriage which can be moved with respect to the base member, wherein the carriage can be moved along the opening direction under the action of the loaded accumulator and in the state of the device assembled on the guide unit drives the mobile rail along the opening direction.

[0020] The device comprises for example a locking assembly with a heart-shaped cam-ramp guide and a locking mechanism which can be contacted along the heart-shaped cam. For example, when the accumulator is loaded in the locked position of the device, then the carriage occupies a locked position, in which the movement of the carriage along the opening direction is locked.

[0021] For example, the connecting element connects the two carriages of the two devices with each other in such a way that the locking of the carriage of one push-out unit and the locking of the carriage of the other push-out unit are cancelled synchronously.

[0022] For example, the linear movement of the slide and the rotational movement of the connecting element about its longitudinal axis take place mechanically coupled by means of the connecting element. For example, the slide and the transmission contour are fixedly or rigidly, for example integrally, connected to one another, for example configured on the slide member. For example, the transmission contour of the slide can be moved linearly, for example can be moved linearly back and forth together with the remaining slide, for example can be moved or can be displaced. For example, the linear movement of the slide takes place temporarily coupled with the linear movement of the furniture part.

[0023] For example, the adapter mechanism is configured in one piece. This enables the adapter mechanism to be advantageously manufactured. For example, the adapter mechanism is composed of a plastic material. The adapter mechanism is, for example, a plastic injection-molded part. For example, the adapter mechanism is alternatively composed of a metal material.

[0024] For example, the locking section of the adapter mechanism is connected to the remaining part of the adapter mechanism by means of a film hinge. The film hinge can be easily manufactured. For example, the film hinge is configured integrally with the locking section and the remaining part of the adapter mechanism. The film hinge is durable or robust. For example, the movability, for example flexibility, of the film hinge can be influenced by a predetermined thickness of the material forming the film hinge and / or material properties of the plastic constituting the film hinge. For example, a preloading force of the film hinge closed in the closed position can also be predetermined thereby.

[0025] For example, the adapter mechanism has a catch, by means of which the locking section can be fixed in the closed position of the locking section. For example, a section of the catch is present on the locking section, and another part of the catch is present on a mating section on the remaining part of the adapter mechanism. For example, the catch can be brought into the closed position by means of a movement of the locking section in the direction of the other part of the catch. For example, the locking section can latch itself in the closed position. For example, the catch can be manually released from the catch 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 the catch. For example, a partial area of the catch can be elastically movable, for example offset.

[0027] For example, the catch is configured for forming a snap connection. For example, the catch comprises a side recess on the locking section and / or a side recess on the remaining part of the adapter mechanism. For example, the catch has a tooth section, which in the connected position fixes a retaining, for example post-bites on a catch edge. For example, the fixed retaining takes place on the basis of a restoring force, which is provided by the elastic properties of the film hinge and / or by a partial area of the catch.

[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 one another. Thereby, for example, a reliable connection of the end section of the connecting element to the adapter mechanism is achieved by a face pressure of the sections facing one another.

[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 blocking section, a form-fit connection between the end section of the connecting element and the adapter mechanism is produced. The outer shape of the end section of the connecting element, for example, comprises an outwardly curved section, wherein the outwardly curved section and the recessed configuration of the inner shape of the receiving section match one another such that the end section of the connecting element and the inner shape of the receiving section, for example, the fixed wall of the inner shape, exactly match one another, for example, without a gap or with a relatively small gap, for example, almost without a gap.

[0030] For example, there is a toothing section of the adapter mechanism, wherein the toothing section is configured axially offset to the receiving section. The axial offset relates to the longitudinal axis of the inserted connecting element. For example, the toothing section is configured as a pinion section, for example, the toothing section is configured as a regularly configured external toothing. For example, the maximum outer diameter of the toothing section is equal to or smaller than the outer diameter of the adapter mechanism in the region of the receiving section.

[0031] For example, the two adapter mechanisms on the respective push-out unit are identically configured. This is easy to assemble and is economically advantageous. For example, the two adapter mechanisms are completely identical.

[0032] For example, the end section of the connecting element is configured externally columnar in the basic shape and has a mating profile 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, which comprises the two end sections and the remaining section present therebetween. Thereby, the initial components making up the connecting element can be cut to any desired length.

[0033] For example, the mating profile is configured linearly outwardly protruding over the basic shape of the connecting element, wherein the basic shape of the connecting element is, for example, columnar or cylindrical.

[0034] For example, the mating profile has two protrusions diametrically opposite with respect to the longitudinal axis. For example, the protrusions are realized with respect to the external basic shape of the connecting element, which is, for example, columnar.

[0035] The mating profile, for example, comprises two outwardly protruding protrusions diametrically opposite externally, which extend in parallel, for example, are convex or outwardly convex.

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

[0037] The blocking section has, for example, a contact profile which can be brought into contact with the connecting element, which contact profile matches the outer profile of the connecting element in order to cooperate in contact in the closed position of the blocking section. Thereby, the connecting element can be connected to the adapter mechanism in a torsion-proof manner.

[0038] For example, a guide rail is proposed which comprises two guide units, each having a fixed rail which can be connected with a furniture body and a mobile rail which can be coupled with a furniture part, wherein there is a device according to one of the preceding configurations.

[0039] For example, a furniture is proposed which has a furniture body and a movable furniture part, wherein a guide rail as described before is provided. BRIEF DESCRIPTION OF DRAWINGS

[0066] The section of the adapter mechanism 23, which is adjacent to the toothing section 24, has a latching section 26, which is able to oscillate relative to the remaining adapter mechanism 23 by means of a film hinge 27, for example a hinge. The latching section 26 can be latched by means of a catch 28 with the end of the latching section, which is remote from the film hinge 27, in order to latch the latching section 26 in its closed position according to Figure 11 and 12 , however this view does not show the view of the connecting element 10, in order to fix the inserted connecting element 10.

[0067] The receiving portion 22 has a wall 25, which is configured in the circumferential direction relative to the rotational axis of the introduced connecting element 10.

[0068] The push-out units 7 and 8 serve as push-out devices, on which the synchronizer 9 can be arranged accordingly by means of the adapter mechanism 23 and the connecting element 10.

[0069] In the push-out unit 8 of a guide unit with a fixed rail 4 and a moving rail 6 for a partially telescopic slide rail according to Figure 13 , the heart-shaped cam 18 is oriented downwards or open downwards or oriented downwards in the use state on the furniture, which is shown by Figures 14-16 .

[0070] The ejection unit 8 operates on the same principle as the ejection unit 7 or 8 used for guide units 2 and 3, which are respectively configured as fully telescopic slide rails. It is constructed to... Figure 13 The structure consists of a guide unit 8 that is partially telescopic slide rail and can be arranged on the moving rail 6. Figure 13 The invisible driving element that interacts with the ratchet mechanism 15 exists on the fixed rail 4.

[0071] exist Figure 16 The locking member 20 of the ejection unit 8 is not shown.

[0072] exist Figure 15 and 16 The connecting housing 13 of the ejection unit 8 is not shown in the figure.

[0073] The external shape of the connecting element 10 has, for example, a mating profile having two protrusions 10a, 10b that are radially opposed to the longitudinal axis of the connecting element 10.

[0074] The locking section 26 has, for example, a contact profile 26a that can contact the connecting element, the contact profile matching the outer profile of the connecting element 10 to engage with the connecting element 10 in the closed position of the locking section 26. For example, the contact profile 26a sealably abuts against the protrusion 10b and the sections of the outer profile of the connecting element 10 adjacent to each other on both sides of the protrusion.
