Abstract

The present invention relates to a fastening device for fastening to a furniture panel. The fastening device comprises at least two dowels for reception in furniture panel recesses. The dowels are each connected to lateral ends of lever arms. The lever arms are centrally connected to each other at a hinge joint. One dowel may be displaced in relation to the other dowel between a furniture panel fastening position and a furniture panel releasing position of the fastening device. A fastening system for joining furniture parts, comprising the fastening device, is also disclosed. A method for using the fastening system is described as well as furniture assemblies using the system.

First claim

The invention claimed is:

1. A fastening device for fastening to a first furniture panel and a second furniture panel, the fastening device comprises: at least two dowels for reception in oblong furniture panel recesses of the first furniture panel, each dowel is connected to a respective lateral end of lever arms of a lever and each dowel is configured to move axially and laterally, the lever arms are connected to each other at a hinge joint, wherein the dowels are displaceable in relation to each other between a furniture panel fastening position, in which the fastening device is secured to the second furniture panel, and a furniture panel releasing position, in which the fastening device is removable from the second furniture panel, wherein the dowels are displaceable in a plane defined by an extension of the first furniture panel by movement of the hinge joint in a direction perpendicular to the plane defined by the first furniture panel.

2. The fastening device according to claim 1 , wherein the dowels are configured to be displaceable in relation to each other in a fastening direction, and wherein displacement of the dowels is effected by maneuvering the hinge joint in a direction being different from the fastening direction, wherein the movement of the dowels in relation to each other is linear.

3. The fastening device according to claim 1 , further comprising at least one pulling ridge protruding axially from the lever, wherein the at least one pulling ridge is configured to pull the dowels axially inwards into the fastening device when the fastening device is in fastening position.

4. The fastening device according to claim 1 , further comprising at least one locking ridge protruding from the lever, wherein the at least one locking ridge is arranged to rest against an inner wall of a compartment of a front part when the fastening device is in fastening position, requiring a larger initial force to move the fastening device to releasing position.

5. A fastening device for fastening a first furniture part to a second furniture part, wherein the fastening device comprises:
at least two dowels for reception in oblong recesses of the second furniture part, the dowels are each connected to a respective lever arm of a lever and each is configured to move axially and laterally,
the lever arms are connected to each other at a hinge joint, such that the dowels are displaced in relation to each other between a fastening position and a releasing position of the fastening device,
wherein when the fastening device is folded, so that the lever arms are pivoted around the hinge joint, the dowels are arranged closer to each other than when the fastening device is unfolded, and wherein when unfolded, the angle of the hinge joint is approximately 180° and the dowels are in the fastening position, and
a locking member being configured to be in an engaged position, for securely attaching the fastening device to the first furniture part, when the dowels are in the fastening position.

6. The fastening device according to claim 5 , wherein the lever arms comprises a side flange extending in an axial direction of the dowels, and a support web, wherein:
the side flange is perpendicular to the support web,
the side flange and the support web extend across the hinge joint,
the at least two dowels extend from the support web, and
the support web is configured to be folded when the fastening device is in an open configuration, and is extending linearly when the fastening device is in a closed configuration, and wherein
said fastening device is formed integrally as one piece.

7. The fastening device according to claim 6 , wherein the locking member is located on the side flange of the fastening device on the side facing the first furniture part, and wherein the locking member is snap actuated and comprises a cantilever portion, a lip portion and a resilient base portion, wherein the base portion is positioned between the cantilever portion and the lip portion thus acting as a fulcrum.

8. The fastening device according to claim 6 , wherein at least one of the dowels comprises a guide portion at the proximal end of the dowel contacting the support web.

9. A fastening system for the joining of a first furniture part and a second furniture part for assembly of said furniture parts to each other, comprising a fastening device according to claim 5 , a first furniture part and a second furniture part, wherein
the first furniture part comprises a connecting slot and an L-flange perpendicular to the main plane of the first furniture part, wherein the first furniture part comprising at least two holes,
the second furniture part comprises at least two recesses of an oblong shape, the two recesses each comprises one insertion opening at one end and an inner end at the other end, the insertion openings of the recesses laterally facing towards or away from each other, the recesses comprising at least one groove which co-operates with at least one ridge on the dowels of the fastening device, where the at least one groove and the at least one ridge are both in the same plane, such that the dowels of the fastening device can be pushed into the recesses of the second furniture part when the fastening device is in a releasing position,
the arrangement of the two holes of the first furniture part corresponds to the arrangement of the at least two recesses of the second furniture part, such that the L-flange of the first furniture part can be positioned on the second furniture part, such that the at least two holes overlap the at least two recesses, such that the at least two dowels of the fastening device can be inserted through the at least two holes into the at least two recesses, when the fastening device is in an open configuration, and
when the inserted fastening device is brought to a closed position, the fastening device locks the first furniture part to the second furniture part by wedging the L-flange between the fastening device and second furniture part.

10. The fastening system according to claim 9 , wherein the locking member of the fastening device is configured to snap into the connecting slot when it reaches closed configuration, reversibly locking the fastening device to the first furniture part and in closed configuration or wherein a guide portion is configured to interact with the holes in the first furniture part to steer the first and second furniture parts into a correct mounted position.

11. A fastening system for joining a first furniture panel and a second furniture panel for assembly of said furniture panels to each other, comprising a fastening device according to claim 1 , the first furniture panel, and the second furniture panel, wherein:
the fastening device is mounted on or integrated in the first furniture panel,
the second furniture panel comprises at least two recesses of an oblong shape, the two recesses each comprises one insertion opening at one end and an inner end at another end, the recesses comprising at least one groove which co-operates with at least one ridge on the dowels of the fastening device and the at least one ridge and the at least one groove are both in the same plane, such that the dowels of the fastening device can be pushed into the recesses of the second furniture panel when the fastening device is in a releasing position, and the furniture panels are joined together when the fastening device is in a fastening position, whereby the dowels are at the inner ends of the recesses, securely joining the furniture panels together.

12. A fastening system according to claim 11 , wherein the at least one groove of the respective recess is tapered, such that a first groo
