A drawer pull-out guide including an automatic retraction device having a pawl component with a receptacle that receives a catch on a running rail as the rails move relative to the guide rail when approaching a closed position and an entraining rocker. During a final part of retraction movement of the pawl component, the entraining rocker being coupled to and movable with the pawl component; and during an initial displacement path of the pawl component the entraining rocker being decoupled from the pawl component and retained against longitudinal displacement in the pawl housing. A first spring biasing the pawl component into a first end position and locking the pawl component; and a second spring for biasing the entraining rocker in a direction of retraction engages on the entraining rocker.

A humerus implant for a reverse shoulder prosthesis has a cup shaped body and a thread at the outside of the body. The thread has a plurality of fins with cut-outs between the fins. At least one fin has an inclined leading surface which helps in incising into the bone by rotating the body in an inward direction. Furthermore, at least one fin has a forward oriented undercut trailing surface blocking rotation in the outward direction.

A humerus implant has a stem, cup shaped body and a locking adapter. The cup shaped body is locked to the stem by a key-slot mechanism. The cup shaped body has a center portion and a plurality of flexible first sidewall segments and second sidewall segments, with gaps between neighbored sidewall segments. The first sidewall segments have a plurality of locking fins while the second sidewall segments having a plurality of recesses and holes. The locking adapter has means for fixing the locking adapter to the cup shaped body and a locking ring for locking the sidewall segments into their final positions.

The invention relates to a key, which comprises a bottom plate, a key cap with a key cap major axis, a lifting mechanism, a spring-back device and a supporting mechanism, wherein the lifting mechanism is arranged between the bottom plate and the key cap and comprises a first plate-shaped support and a second plate-shaped support; the first plate-shaped support comprises a first side part and a second side part parallel to the key cap major axis for abutting against the bottom plate and the key cap respectively; the second plate-shaped support comprises a third side part and a fourth side part parallel to the key cap major axis for abutting against the bottom plate and the key cap respectively; part of the bottom plate enters accommodating openings of the first plate-shaped support and the second plate-shaped support to enable the first plate-shaped support and the second plate-shaped support to be movably connected onto the bottom plate; the spring-back device is used for driving the key cap to be returned to an un-pressed position along with pivoting of the first plate-shaped support and the second plate-shaped support relative to the bottom plate via the first side part and the third side part; and the supporting mechanism comprises a first supporting piece and a second supporting piece which are pivoted mutually to be movably connected between the key cap and the bottom plate. The pulling force of the key cap can be increased, and the problem that the key cap of a multiple key is likely to fall can be solved effectively.
