Abstract

A fastening device ( 2;20 ) for assembling panels ( 170;180 ) in furniture, the device ( 2;20 ) having an axial extension along an axial direction and a lateral extension along a lateral direction, said device ( 2;20 ) comprising an upper part ( 4;40 ), and a lower part ( 5;50 ) a circumferential extending peripheral surface ( 10;110 ), the device ( 2;20 ) having an axially extending through passage ( 8;80 ) for the insertion of a pin the in the axial direction, wherein the fastening device ( 2;20 ) comprises elements for taking up forces along both the axial and lateral direction.

First claim

The invention claimed is:

1. A fastening device for assembling panels in furniture, the device having an axial extension along an axial direction and a lateral extension along a lateral direction, said device comprising:
an upper part;
a lower part;
a circumferential extending peripheral surface at least partly comprising a curved surface constructed to fit in a bore hole of a first furniture part when assembled, and a flat surface constructed to fit and clamp against a flat surface of a second furniture part when the first furniture part and the second furniture part are assembled together; and
an axially extending through passage for the insertion of a pin in the axial direction, wherein the upper part comprises a top surface and the lower part comprises a bottom surface, wherein the fastening device comprises a first slit arranged in the axial direction extending from the upper part of the fastening device and a second slit extending in the axial direction in the lower part of the fastening device, and wherein the first slit is arranged from the top surface of the upper part, extending in the axial direction, and the second slit is arranged from the bottom surface of the lower part extending in the axial direction, such that the upper part and the lower part are expandable upon insertion of the pin in the through passage.

2. A fastening device according to claim 1 , wherein the fastening device comprises protrusions arranged on the peripheral surface of the fastening device.

3. A fastening device according to claim 2 , wherein the protrusions are formed as circumferential flanges on the curved surface.

4. A fastening device according to claim 2 , the upper part having a wider upper portion and a narrower lower portion, wherein the wider upper portion is arranged to lock the upper part to a surface of the furniture when the fastening device is inserted in a hole with narrower dimension than the wider upper portion.

5. A fastening device according to claim 2 , wherein the protrusions are arranged to extend in the axial direction and also in a direction transversal thereto of the fastening device.

6. A fastening device according to claim 2 , wherein the protrusions having an extension from the peripheral surface of about 0.1-3 mm.

7. A fastening device according to claim 1 , wherein a further slit is arranged in from the bottom surface of the lower part, extending in the axial direction.

8. A fastening device according to claim 2 , wherein the protrusions are formed as grooves on the flat surface.

9. A fastening device according to claim 1 , wherein a further slit is arranged in from the top surface of the upper part, extending in the axial direction.

10. A fastening device according to claim 9 , wherein the slits arranged in the upper part also extends into the lower part and that the slits arranged in the lower part also extends into the upper part.

11. A furniture assembly comprising a fastening system according to claim 10 , and a first furniture part comprising a bore hole for receiving the curved surface, and a second furniture part having a flat surface for fitting and clamping to the flat surface of the fastening device.

12. A fastening system comprising a fastening device according to claim 1 , further comprising the pin for insertion into the through passage of the fastening device.

13. A furniture assembly comprising a fastening system according to claim 12 , wherein the first furniture part further comprises a recess allowing for insertion of the second furniture part therein.
