Abstract: A bracket for joining tables and/or table tops, includes a first bracket member adapted for attachment to one table or table top and having at least one hook-like projection, a second bracket member adapted for attachment to another table or table top to be joined and having at least two hook-like projections for so cooperating with the first bracket member that the projection of the first bracket member interlocks between the projections of the second bracket member. A connection element made of elastic and deformable material is placed between the projections of the first and second bracket members such that the projections of the first and second bracket members partially encompass the connection element, with the connection element generating a clamping force acting upon the projections of the first and second bracket members while being subject to an elastic deformation, thereby bracing the first and second bracket members with one another.

Abstract: An adjustment mechanism includes two structural elements movable relative to one another, with a first structural element being formed with at least one row of substantially cycloidal teeth and with a second structural element including a drive element guided transversely to a direction of adjustment and formed with at least two driving pins capable of rolling over the teeth. The second structural element has at least one attack surface bearing upon an outer envelope of the drive element and is defined by a line of action extending through a line which is oriented essentially between axes of two driving pins engaging in tooth spaces between teeth and bearing upon a bottom land. In this manner, the drive element is pressed in each respective locked position with its driving pins into the bottom land by gravitational forces.
