Abstract

A connection arrangement for connecting a first furniture part (10) to a second furniture part (20), wherein the first furniture part (10) comprises: a dowel (11) and one or more abutment surfaces (13) extending circumferentially (C) around or being distributed circumferentially (C) around the dowel (11), wherein the second furniture part (20) comprises: a through-going opening (22) extending through a wall (21) and one or more abutment surfaces (23) extending circumferentially (C) around or being distributed circumferentially (C) around the through-going opening (22), wherein the connection arrangement further comprises a connection member (30) having a recess (31), the recess (31) having a locking portion (31b) being configured to receive the dowel (11) by a relative motion between the connection member (30) and the first furniture part (10) in a direction transverse (T) to the longitudinal direction (L) and being configured to interact with the neck portion (11b) of the dowel (11) to counteract removal of the dowel (11) from the locking portion (31b) along the longitudinal direction (L).

First claim

The invention claimed is:

1. Connection arrangement for connecting a first furniture part to a second furniture part,
wherein the first furniture part comprises:
a dowel extending from the first furniture part along a longitudinal direction towards a free end of the dowel, the dowel having at least one neck portion, and
one or more abutment surfaces,
wherein the second furniture part comprises:
a through-going opening extending through a wall of said second furniture part, and
one or more abutment surfaces on a first side the wall, the first side facing in a direction opposite the longitudinal direction, the one or more abutment surfaces extending at least partially circumferentially around or being distributed at least partially circumferentially around the through-going opening,
wherein the connection arrangement further comprises a connection member having a recess, the recess having a locking portion being configured to receive the dowel by a relative motion between the connection member and the first furniture part in a direction transverse to the longitudinal direction and being configured to interact with the neck portion of the dowel to counteract removal of the dowel from the locking portion along the longitudinal direction,
wherein the first furniture part and the second furniture part are configured to be connected to each other by
inserting the dowel through the through-going opening from the first side in an insertion direction along the longitudinal direction and bringing said abutment surfaces of the first and second furniture parts into contact with each other, and
positioning the connection member on a second side, opposite the first side of the wall and moving the connection member relative to the dowel in a travel direction along the transverse direction such that the dowel slides into the locking portion,
wherein
the abutment surfaces of the first furniture part have an extension in the longitudinal direction along a portion of the dowel and extending at least partially circumferentially around or being distributed at least partially circumferentially around the dowel,
the abutment surfaces the second furniture part extend from the first side of the wall in a direction opposite the longitudinal direction and extend at least partially circumferentially around or is at least partially circumferentially distributed around the through-going opening, and
the one or more abutment surfaces of the first furniture part and the one or more abutment surfaces of the second furniture part are positioned on the respective furniture part such that, as the dowel is inserted into the through-going opening, the one or more abutment surfaces of the first furniture part abut the one or more abutment surfaces of the second furniture part and counteract relative movement between the first and second furniture parts along a direction transverse to the longitudinal direction.

2. Connection arrangement according to claim 1 , wherein said one or more abutment surfaces of the first furniture part comprises a tubular section extending along the longitudinal direction and extending circumferentially around a base portion of the dowel.

3. Connection arrangement according to claim 2 , wherein said one or more abutment surfaces of the second furniture part e configured to be arranged inside and abut one or more abutments surfaces on an inside of the tubular section.

4. Connection arrangement according to claim 1 , wherein said one or more abutment surfaces of the second furniture part comprises a tubular section extending from the first side of the wall in the direction opposite the longitudinal direction and extending circumferentially around the through-going opening.

5. The connection arrangement according to claim 1 , wherein the dowel of the first furniture part comprises a base portion having an abutment surface adapted to, when the dowel is inserted through the through-going opening of the wall, abut an inner surface of said through-going opening.

6. Connection arrangement according to claim 1 , wherein the recess has an entrance opening in a first surface forming a corner together with a second surface, the first surface being intended to face in the travel direction and the second surface being intended to face the wall of the second furniture part.

7. Connection arrangement according to claim 1 , wherein the recess has a depth as seen from the second surface along a depth direction extending along the longitudinal direction and is, as seen along the depth direction, provided with at least one neck section configured to interact with the neck portion of the dowel, wherein the neck section is formed by two oppositely arranged internal ridges extending along the second surface and facing each other.

8. Connection arrangement according to claim 1 , wherein the first furniture part is a tubular member having a main extension along the longitudinal direction, wherein the dowel is positioned partly into an open end of the tubular member such that it partly extends inside the tubular member and partly extends past the tubular member along the longitudinal direction.

9. Connection arrangement according to claim 1 , wherein the second furniture part is a tubular member having an open end facing in a direction opposite the travel direction of the connection member and having a main extension along the transverse direction.

10. Furniture comprising a first furniture part, a second furniture part and a third furniture part, wherein the first and second furniture parts are connected to each other by a connection arrangement according to claim 1 ,
wherein the third furniture part is tubular, has an open end facing in a longitudinal direction and has a main extension along the longitudinal direction,
wherein the second furniture part comprises or is configured to receive a dowel extending from the second furniture part along a direction opposite the longitudinal direction towards a free end of the dowel,
wherein the dowel has at least one ridge followed, as seen along the longitudinal direction, by at least one valley,
wherein the second and third furniture parts are connected to each other by a connection arrangement which comprises:
a connection member having a recess and being configured to be inserted through the open end and into the third furniture part, wherein the recess has a locking portion being configured to receive the dowel by a relative motion between the third furniture part and the connection member in a direction transverse to the longitudinal direction and being configured to interact with the valley of the dowel counteract removal of the dowel from the locking portion along the longitudinal direction,
wherein the second furniture part and the third furniture part are figured to be connected to each other by
inserting the connection member at least partly into the third furniture part, and
moving the third furniture part with the connection member relative to the dowel in a travel direction along the transverse direction such that the dowel slides into the locking portion of the connection member.

11. Furniture according to claim 10 , wherein the dowel is configured to be attached to a tubular furniture part and to provide a part of a connection arrangement between the tubular furniture part and a third furniture part, the dowel comprising
a connection portion having at least one ridge followed, as seen along a longitudinal direction, by at least one valley, wherein the connection portion is configured to extend from the second furniture part along a direction opposite the longitudinal direction towards a free end of the dowel, and
an attachment portion having a neck portion foll
