Abstract

A door handle pull securable to a surface of a door hinged on one edge thereof, for preventing the securing of lockable items thereto, the door handle pull. The door handle pull comprises a flat door handle grip extending from the door at an acute angle with respect to the door surface and in a direction away from the door surface, the door handle grip having a width tapering from a wider width adjacent the door to a narrower width near a distal end with an edge on the hinge side of the door extending at an acute angle to vertical. The tapered width of the grip and acute angle of the grip edge resists attachment of a locking device to the grip and urges a locking device downward off of the grips as the door is opened and the locking device is tightened.

Claims (20)

1. A door handle pull securable to a surface of a door hinged on one edge thereof, for preventing the securing of lockable items thereto, the door handle pull comprising:

at least one door having a surface, and a hinge side;

a door handle plate for securing the door handle pull to the door surface opposite the hinge side;

a door handle grip extending from the door handle plate at an acute angle with respect to the door surface and in a direction away from the door surface, the door handle grip having a width tapering downward from a wider width adjacent the door to a narrower width near a distal end of the door handle grip with an edge on the hinge side of the door extending at a constant acute angle to vertical;

whereby the tapered width of the grip and acute angle of the grip edge resists attachment of a locking device to the grip and urges a locking device downward off of the grips as the door is opened and the locking device is tightened.

2. The door handle pull of claim 1 wherein the door handle grip is rotatable with respect to the door to increase the angle of the grip edge with respect to vertical and further prevent a locking device from being attached to the grip.

3. The door handle pull of claim 1 comprising a pair of the door handle pulls, each pull being secured to one of a pair of doors at adjacent edges thereof, the tapering angled edges of the door handle grips being on opposite sides of the door handle pulls to prevent a locking device from being attached between the pair of door handle grips.

4. The door handle pull of claim 1 wherein the grip extends from a portion of the door handle plate and the grip is stamped from the door handle plate.

5. The door handle pull of claim 1 wherein the grip is stamped from the door handle plate.

6. The door handle pull of claim 1 wherein the lower end of the grip is parallel to the door surface.

7. The door handle pull of claim 1 wherein the grip taper is non-symmetrical.

8. A door handle pull securable to a surface of a door hinged on one edge thereof for preventing the securing of lockable items thereto, the door handle pull comprising:

at least one door having a surface, and a hinge side;

a door handle plate disposable on the door surface;

a flat door handle grip extending from the door handle plate at an acute angle with respect to the door handle plate and in a direction away from the door handle plate, the door handle grip having a width tapering downward from a wider width at the door handle plate to a narrower width near the distal end of the door handle grip with an edge on the hinge side of the door extending at a constant acute angle to vertical;

whereby the tapered width of the grip and acute angle of the grip edge resists attachment of a locking device to the grip and urges a locking device downward off of the grips as the door is opened and the locking device is tightened.

9. The door handle pull of claim 8 wherein the door handle grip is rotatable with respect to the door to increase the angle of the grip edge with respect to vertical and further prevent a locking device from being attached to the grip.

10. The door handle pull of claim 8 comprising a pair of the door handle pulls, each pull being secured to one of a pair of doors at adjacent edges thereof, the tapering angled edges of the door handle grips being on opposite sides of the door handle pulls to prevent a locking device from being attached between the pair of door handle grips.

11. The door handle pull of claim 8 wherein the grip is stamped from door handle plate.

12. The door handle pull of claim 8 wherein the lower end of the grip is parallel to the door handle plate.
