Abstract
The disclosure relates to a first furniture part adapted to be assembled with a second furniture part. The first furniture part comprises recess and the second furniture part comprises a pin. The recess and the pin has a width which varies along the longitudinal direction (L), thereby forming insertion portions of the recess and core portions of the pin, and respective locking portions. The locking portions are provided with grooves and protrusions. The disclosure further relates to a second furniture part comprising a male part of the joint and to a method of forming a furniture part with a female part of a joint.
Claims7
Furniture part comprising a male part of a joint, wherein the male part of the joint comprises a pin extending from a base of the furniture part along a height direction (H) towards a free end of the pin, the pin having a cross-section with a pin length (PL) extending along a longitudinal direction (L) and a width (W) which is perpendicular to the longitudinal direction (L), which width (W) varies along the longitudinal direction (L),
- wherein the pin has, as seen along the longitudinal direction (L),
- a first portion forming a locking portion and having a first width (W21),
- a second portion connected to the first portion and forming a core portion and having a second width (W22) being smaller than the first width (W21),
- a third portion forming a locking portion and having a third width (W21),
- wherein opposing, longitudinally extending, side wall portions of the first portion are each provided with a first protrusion and a second protrusion extending alongside each other and both extending in the longitudinal direction (L) along the first portion and extending outwardly in the direction of the width (W) from a first portion core width (W20) to said first width (W21), wherein the first protrusion is located at a first height (H23a) of the pin and the second protrusion is located at a second height (H23b) of the pin, which second height (H23b) is larger than the first height (H23a),
- wherein opposing, longitudinally extending, side wall portions of the third portion are each provided with a first protrusion and a second protrusion extending alongside each other and both extending in the longitudinal direction (L) along the third portion and extending outwardly in the direction of the width (W) from a third portion core width (W20) to said third width (W21), wherein the first protrusion is located at a first height (H23a) of the pin and the second protrusion is located at a second height (H23b) of the pin, which second height (H23b) is larger than the first height (H23a), and
- wherein, at the transition between the first and second portion and at a portion of the third portion facing away from the second portion, respective protrusion comprises an initial portion formed by a gradual increase in height of upper and lower wall portions of the cross-section of the protrusion as seen counter to the longitudinal direction (L).
