Abstract
The invention provides a locking wall hanger having a pointed end, which is designed to create a hole in the wall as the hanger is inserted therethrough. Whereas a self-boring tip penetrates the wall and embeds itself in the rear wall surface a mid-parabolic portion of the hanger is adjusted to provide a spring force for locking the hanger to the wall. In order to compensate for an undue tilt of the hanger in its final assembly position, the angle between a hook portion protruding from the wall's front side and shank portion penetrating the wall is smaller than 90°. Further the invention provides an adapter piece being adapted to be supported by the hanger.
Claims23
A wall hanger (10) for mounting in a wall for hanging objects thereon comprising a one-piece metal wire having:
- a wall penetrating tail portion (20) with a pointed free end (22) being adapted to penetrate a wall,
- a resilient C-shaped intermediate portion (18) adjacent to the tail portion (20),
- a substantially straight shank portion (16) adjacent to the intermediate portion (18) being adapted to penetrate the wall (30) upon locking of the hanger in a final assembly position,
- a hook portion (11) adjacent to the shank portion (16) having a hook-like geometry and being adapted to receive objects for hanging thereon,
- wherein at an intermediate assembly position by insertion of the first metal wire into the wall (30) from the wall's front side, the pointed tail portion (20) contacting a rear side of the wall (30) and in response to further insertion of the metal wire, the C-shaped intermediate portion (18) being adapted to be resiliently deformed applying a spring force to the tail portion (20) and providing a locking of the first metal wire in the wall (30) when reaching a final assembly position,
- wherein the hook portion (11) further comprises an abutment piece (14) being adapted to abut against the wall's front side when reaching the final assembly position, the abutment piece (14) extending at an angle of less than 90° with respect to the direction of elongation of the adjacent shank portion (16).
A wall hanger (10) for mounting in a wall for hanging objects thereon comprising a one-piece metal wire having:
- a wall penetrating tail portion (20) with a pointed free end (22) being adapted to penetrate a wall,
- a resilient C-shaped intermediate portion (18) adjacent to the tail portion (20),
- a substantially straight shank portion (16) adjacent to the intermediate portion (18) being adapted to penetrate the wall (32) upon locking of the hanger in a final assembly position,
- a hook portion (11) adjacent to the shank portion (16) having a hook-like geometry and being adapted to receive objects for hanging thereon,
- wherein at an intermediate assembly position by insertion of the metal wire into the wall (30) from the wall's front side, the pointed tail portion (20) contacting a rear side of the wall (32) and in response to further insertion of the metal wire, the C-shaped intermediate portion (18) being adapted to be resiliently deformed applying a spring force to the tail portion (20) and providing a locking of the metal wire in the wall (32) when reaching a final assembly position,
- wherein the hook portion (11) has a U-shaped geometry and comprises an abutment piece (14), an end portion (12) and an arch portion (26) connecting the abutment piece (14) and the end portion (12), wherein the abutment piece (14) and the end portion (12) extend rectilinear and substantially parallel with respect to each other.
