Connection mechanism for connection of armrests to tables or chairs

A connecting mechanism comprising:

• an essentially flat planar base element (1) having an essentially flat planar fastening section (1a) for fastening onto a surface of a piece furniture by means of said flat planar base element (1), and wherein the fastening section (1a) include a socket unit (1b) having a longitudinal axis (P2) parallel to an insertion direction of said socket unit (1b) for detachably receiving an area (2b) of a fastening element (2), and wherein said longitudinal axis of said socket unit (1b) is parallel to said flat planar fastening section (1a);
• the fastening element (2) configured for attaching to a part which is to be detachably connected to the piece of furniture, wherein the fastening element (2) is configured for being detachably connected parallel to the fastening section (1a);
• and a securing device (3), configured for engaging with the area (2b) of the fastening element (2) when the area (2b) of the fastening element (2) is received in the socket unit (1b), wherein the securing device (3) is adjustably coupled to said socket (1b) such that said securing device (3) may be adjusted inward and outward on said socket unit (1b) in a direction along said longitudinal axis of said socket unit (1b), and wherein the securing device (3) includes an engagement element (3a) which is pre-tensioned in a first perpendicular direction towards the area (2b) of the fastening element (2) when received in the socket unit (1b), wherein the engagement element (3a) engages in a recess (2c) provided in the area (2b) of the fastening element (2) and wherein the recess (2c) is formed as a groove in the area (2b) of the fastening element (2), wherein the engagement element (3a) includes an opening (3f) through which the area (2b) of the fastening element (2) is configured to pass, wherein the opening (3f) includes an edge (3g) which is configured to enter into and engage with the recess (2c), wherein the securing device (3) has an actuating element (3b) for moving the engagement element (3a) in a second perpendicular direction (P1) that is perpendicular to said longitudinal axis (P2) and opposite said first perpendicular direction, and wherein the engagement element (3a) is pre-tensioned in said first perpendicular direction toward the fastening element (2b) which is received in the socket unit (1b) by means of a spring (3e) imparting a spring tension, and wherein when said engagement element (3a) is moved in said second perpendicular direction against said spring tension and then subsequently released, the engagement element (3a) moves in the first perpendicular direction to allow removal of the fastening element (2) from within the socket unit (1b).
