Guide carriage for movable storage of a piece of furniture

Description

[0001] The present invention relates to a guide carriage for the movable mounting of a furniture part on a guide rail, wherein the guide carriage has a chassis with at least one rotatably mounted roller and at least one connecting part for connecting the guide carriage to the furniture part, wherein the chassis and the connecting part are designed as separate structural units and can be connected to one another via at least one fastening device, wherein the fastening device has at least one energy accumulator and at least one locking element that can be acted upon by the energy accumulator, wherein the chassis and the connecting part can be releasably locked to one another by a force from the energy accumulator, wherein a holding device separate from the fastening device is provided for fastening the connecting part to the chassis.

[0002] Furthermore, the invention relates to a guide system for the movable mounting of a furniture part, wherein the guide system has at least one guide rail and at least one guide carriage of the type to be described which can be moved on the guide rail.

[0003] Furthermore, the invention relates to a piece of furniture comprising a furniture body and at least one furniture part mounted so as to be movable relative to the furniture body and comprising a guide system of the type to be described.

[0004] Guide carriages are used for the movable mounting of a furniture part, for example a door leaf, along a guide rail, whereby the guide carriage is connected to the furniture part via a connecting part in an assembled state on the one hand and is mounted so that it can move along the guide rail on the other hand by the chassis.

[0005] In DE 39 03 700 A1, Fig. 1 A guide carriage for the movable mounting of a folding door along a guide rail is shown. The guide carriage has a chassis with rollers and hinges for the movable mounting of a door leaf. The hinges are mounted on a base plate, which is adjustably arranged on a mounting plate of the chassis. A slotted hole is provided in the mounting plate for this purpose, whereby the base plate can be clamped in a desired position relative to the mounting plate using a locking screw. However, there is a risk that the locking screw could accidentally come loose, meaning that the adjusted position of the hinges can no longer be maintained. If the locking screw is lost, this would lead to the door leaf connected to the hinges crashing down.

[0006] EP 2 894 285 A1 and EP 0 610 557 A1 each show two-part guide carriages for the movable mounting of door leaves, wherein the guide carriage comprises a chassis movable along a guide rail and a separate connecting part for fastening the door leaf. The chassis and the connecting part can be releasably locked together via a widened head part, wherein at least one spring-loaded locking lever is provided for locking the head part. The disadvantage of this is that the installation of the door leaf on the chassis is considerably more difficult, especially with heavy door leaves. To install the door leaf, the head part must be inserted precisely into an insertion opening of the locking device. Furthermore, when connected, the door leaf can be pivoted between the chassis and the connecting part about a horizontally extending axis formed by the guide carriage.This has the disadvantage that the door leaf can be lifted relatively far from the furniture body in an area close to the floor. This can lead to undefined movement of the door leaf, undesirable jamming of the guide carriage components, and excessive mechanical stress on the guide carriage and other furniture components.

[0007] Other relevant documents are US2009 / 289463 , DE 9300918U1 , WO2004 / 040091 and US3829929.

[0008] The object of the present invention is to provide a guide carriage of the type mentioned at the outset while avoiding the disadvantages discussed above.

[0009] This is achieved according to the invention by the features of patent claim 1. Further advantageous embodiments of the invention are specified in the dependent claims.

[0010] According to the invention, it is provided that the connecting part can be suspended from the chassis via the holding device, can be pivoted about a preferably horizontal axis in the suspended state and can be locked to the chassis via the at least one locking element.

[0011] A holding device separate from the fastening device results in a particularly tilt-proof arrangement of the connecting part on the chassis.

[0012] In this case, it can be provided that the holding device and the fastening device are spaced apart from one another in a vertical direction in an assembled state. In a first assembly step, the connecting part can be suspended from the chassis via the holding device. Subsequently, the connecting part suspended from the chassis is pivoted about an axis and finally locked to the chassis via the at least one locking element.

[0013] The fastening device has at least one locking element acted upon by an energy accumulator for establishing the connection between the chassis and the connecting part, whereby the connection between the chassis and the connecting part can be secured by a force from the energy accumulator. The locking between the chassis and the connecting part can be released by moving the locking element by exerting force against the force of the energy accumulator.

[0014] The locking element can have at least one recess that can be brought into engagement with a coupling element arranged on the chassis or on the connecting part. The coupling element can be substantially cylindrical. The coupling element can be designed, for example, as a preferably cylindrical pin or as a preferably cylindrical rod. Thus, in a locking position, the locking element is positively locked to the coupling element, so that the locking element and the coupling element assume a defined end position relative to one another in the locking position.

[0015] According to one embodiment, it can be provided that the at least one locking element is pivotably mounted about an axis, which preferably runs horizontally in an assembled state. Alternatively, it can be provided that the locking element is displaceably mounted, preferably linearly, and is pretensioned toward a locking position by a force from the energy accumulator.

[0016] The energy storage device for applying force to the locking part can, for example, comprise a mechanical spring element, such as a helical spring, a leg spring, or a spiral spring. Alternatively, the energy storage device can also be formed by the inherent elasticity of the locking element.

[0017] Further details and advantages of the invention will become apparent from the following description of the figures.

The U-shaped section 12 has a base web 12a and two legs 12b and 12c projecting downwards from the base web 12a, wherein, in an assembled state, the at least one rotatably mounted roller 17a, 17b is mounted on a first leg 12b and the connecting part 13 can be arranged on a second leg 12c of the U-shaped section 12.

[0022] According to a preferred embodiment, for the purpose of convenient assembly, it can be provided that: in a first assembly step, the chassis 11 is mounted on the guide rail 7 independently and separately from the connecting part 13, in a second assembly step, the connecting part 13 is mounted on the furniture part 3a independently and separately from the chassis 11, in a third assembly step, the furniture part 3a is connected to the chassis 11 mounted on the guide rail 7 via the connecting part 13 attached thereto by means of at least one fastening device 18.

[0023] Fig. 3 shows the guide carriage 5a in a cross-section. The chassis 11 has at least one roller 17a, 17b, which can be moved along the guide rail 7. In the illustrated embodiment, two or more rollers 17a, 17b are provided, which are spaced apart from one another in a vertical direction. A first roller 17a has a substantially horizontal axis of rotation in an assembled state, while a second roller 17b is rotatable about a substantially vertical axis of rotation in an assembled state. The rollers 17a, 17b are mounted on the first leg 12b of the U-shaped section 12, while the connecting part 13 for fastening the furniture part 3a is to be mounted on the second leg 12c of the U-shaped section 12. The connecting part 13 has a fitting part 14 pivotable about the vertical axis 27 and having the fastening points 15 ( Fig. 2b ) for fastening to furniture part 3a.

[0024] The connecting part 13 is to be mounted on the chassis 11 via at least one fastening device 18. The fastening device 18 comprises at least one movably mounted locking element 19, which is pretensioned towards a locking position by an energy accumulator 21 (for example in the form of a helical spring, a leg spring, or a spiral spring). The locking element 19 can be releasably locked to a coupling element 22 arranged on the chassis 11. The locking element 19 is provided with at least one recess 23, which can be brought into engagement with the coupling element 22 arranged on the chassis 11. In the exemplary embodiment shown, the locking element 19 is pivotally mounted about an axis 20 that runs horizontally in an assembled state.

[0025] According to the invention, a holding device 24, separate from the fastening device 18, is provided for fastening the connecting part 13 to the chassis 11. The holding device 24 and the fastening device 18 are spaced apart from one another in a vertical direction in an assembled state. The holding device 24 has at least one notch 25 arranged on the connecting part 13 for suspending the connecting part 13 on the chassis 11. At least one holding element 26 is arranged or formed on the chassis 11, which engages in the notch 25 when the connecting part 13 is fastened. In a first assembly step, the connecting part 13 can be suspended from the chassis 11 via the holding device 24. Subsequently, the connecting part 13 suspended from the chassis 11 is pivoted about an axis 16, preferably formed by the holding element 26, and finally releasably locked to the chassis 11 via the at least one locking element 19.

[0026] Fig. 4 shows the locked state of the connecting part 13 on the chassis 11 in a cross-section. By hooking the notch 25 of the holding device 24 onto the holding element 26, the connecting part 13 can be pivoted about a horizontally extending axis 16 relative to the chassis 11. The fastening device 18 with the locking element 19 can establish a positive locking connection between the connecting part 13 and the chassis 11. When the locking element 19 interacts with the coupling element 22, the locking element 19 is first moved against a force of the energy accumulator 21; then the locking element 19 can be automatically locked to the coupling element 22 by the force of the relaxing energy accumulator 21. In a locked state, the connection between the connecting part 13 and the chassis 11 can be released by exerting force on the locking element 19 against the force of the energy accumulator 21.In a locked state between the connecting part 13 and the chassis 11, the locking element 19 is freely accessible and directly operable for manual operation or for operation by means of a tool by a person.

[0027] In the illustrated embodiment, the locking element 19 of the fastening device 18 and the notch 25 of the holding device 24 are arranged or formed on the connecting part 13. In a kinematic reversal, it is also possible for the locking element 19 of the fastening device 18 and the notch 25 of the holding device 24 to be arranged on the chassis 11, in which case the coupling element 22 and the holding element 26 would have to be arranged on the connecting part 13.

[0028] Fig. 5 shows the guide carriage 5a with the chassis 11 and the connecting part 13 to be attached thereto in a perspective view. The chassis 11 can have several rollers 17a with a horizontal axis of rotation and several rollers 17b with a vertical axis of rotation. In the figure shown, the connecting part 13 is pre-positioned on the chassis 11 by the holding device 24, wherein the holding element 26 of the holding device 24 is inserted into the notch 25 ( Fig. 3 ) of the connecting part 13. Starting from the Fig. 5 In the position shown, the connecting part 13 can be pivoted about a horizontally extending axis 16 formed by the holding element 26, whereupon the locking element 19 pretensioned by the energy accumulator 21 can automatically lock it with the coupling element 22 of the chassis 11. The coupling element 22 of the fastening device 18 and / or the holding element 26 of the holding device 24 can be designed as a cylindrical pin or as a cylindrical rod. The locking element 19 can be provided with an inclined surface 19a, by means of which the locking element 19, when interacting with the coupling element 22, can be moved against the force of the energy accumulator 21 in a first direction of rotation, so that the energy accumulator 21 is charged.When the coupling element 22 enters the recess 23 of the locking element 19, the locking element 19 is moved by the force of the charged energy accumulator 21 in a second direction of rotation opposite to the first direction of rotation, wherein the locking element 19 can be positively locked to the coupling element 22.

[0029] Fig. 6 shows the guide carriage 5a in a further perspective view. The connecting part 13 is pre-positioned at a predetermined height relative to the chassis 11 via the holding device 24 (holding element 26 in notch 25). The connecting part 13 can be releasably locked to the chassis 11 by the locking element 19. The locking element 19 can have an actuating section 19b, wherein the locking can be released by actuating the actuating section 19b manually or by using a tool.

[0030] The guide carriage 5a further comprises at least one adjustment device 28 with a movably mounted adjustment element 28a, wherein a position of the connecting part 13 relative to the chassis 11 can be adjusted by actuating the adjustment element 28a in a locked state between the connecting part 13 and the chassis 11. It can be seen that the fitting part 14 of the connecting part 13 is pivotally mounted about a vertical axis 27 relative to a bearing part 30. The adjustment device 28 comprises at least one movably mounted adjustment element 28a, wherein a position of the fitting part 14 relative to the chassis 11 can be adjusted by actuating the adjustment element 28a. In the illustrated embodiment, the adjustment device 28 is designed to adjust a height of the fitting part 14. The adjustment element 28a is mounted on a support part 29 so as to be rotatable but axially immovable.The support part 29 rests on the coupling element 22, with a threaded portion 28b of the adjusting element 28a being in threaded engagement with the bearing part 30. By rotating the adjusting element 28a using a tool, the height of the bearing part 30 and thus the height of the fitting part 14 can be adjusted, so that in an assembled state, the height of the furniture part 3a connected to the fitting part 14 can also be adjusted. Of course, further adjustment devices 28 can also be provided, by means of which the fitting part 14 can be adjusted in a lateral direction and / or in a depth direction relative to the chassis 11.
