Abstract
Door stops are generally discussed herein for stopping door knobs or other door hardware from slamming against a wall with particular discussions on door stops having dampening means. Aspects of the door stop assemblies discussed herein include the use of a helical coil spring spacer for delimiting movement of a door and either a pliable insert or an outer sheath or both for dampening the spring when the same is impacted. A combination magnet and magnetically attractable plate or two magnets with opposite magnetic poles may be used to temporary secure a door in a fixed position.
Claims19
A door stop assembly comprising a non-metallic spacer Body, a magnet located at a tip of the spacer body and an anchor screw embedded, at least in part, at a base of the spacer body and having a threaded shaft extending axially of the base;
- and
- wherein a portion of the anchor screw embedded in the spacer body comprises a first extended surface to prevent pitching and yawning and a second extended surface to prevent rolling of the anchor screw relative to the spacer body.
A method for preventing door slam comprising:
- placing a strike plate against a permanent magnet or a ferromagnetic material located on a door stop spacer body;
- placing double-sided adhesive tape against the strike plate;
- and
- swinging a door to axially compress the door stop spacer body and to compress the double-sided adhesive tape.
The method of claim 13, further comprising holding the door stop spacer body and rotating the threaded shaft into a base board, a wall, or a door.
The method of claim 15, wherein the first extended surface comprises a first planar surface that is generally orthogonal to an axis defined by the threaded shaft and the second extended surface comprises a second planar surface that is generally orthogonal to the first planar surface.
A door stop assembly comprising a non-metallic spacer body, a magnet located at a tip of the spacer body and an anchor screw embedded, at least in part, at a base of the spacer body and having a threaded shaft extending axially of the base:
- a metallic strike plate for striking against the magnet;
- and
- wherein a portion of the anchor screw embedded in the spacer body comprises a first extended surface to prevent pitching and yawning and a second extended surface to prevent rolling of the anchor screw relative to the spacer body.
- wherein the first extended surface comprises a first planar surface that is generally orthogonal to an axis defined by the threaded shaft and the second extended surface comprises a second planar surface that is generally orthogonal to the first planar surface.
The door stop assembly of claim 17, further comprising double-sided tape adhered to a surface of the strike plate.
The door stop assembly of claim 18, wherein the magnet has a nominal diameter section and an extended section that is wider than the nominal diameter section to define a gripping surface for the non-metallic spacer body to grip.
