Abstract

A hinge-pin doorstop made of spring-steel bent to provide a loop through which the hinge pin on the door hinge fits for mounting purposes, and having a pair of resilient arms which extend radially from the loop in spaced relation to each other, so that when they are pinched between the door and the molding on the door frame, they absorb the shock of the door, thereby preventing damage to the door or frame.

Claims

1. A hinge-pin doorstop formed from a continuous length of steel and having

a loop-position adapted to encircle the hinge pin,

a first arm-portion extending generally radially from said loop-position,

a bumper-member mounted on said first-arm portion in position for engagement with the door,

a second arm-portion extending generally radially from said loop-portion into spaced relationship with respect to said first arm-portion,

a second bumper-member mounted on said second arm-portion in position for engagement with the door frame,

said arm-portions being disposed such that when the door is swung open the desired amount said arm-portions are squeezed between the door and frame resiliently stopping the door from opening farther, the resilience of said arm-portions being sufficient to absorb enough of the force exerted by the door against them to prevent damage to the surfaces of the door and frame at the points engaged by said bumper-members.

2. A hinge-pin doorstop as defined in claim 1, wherein each of said bumper-members is separably mounted on its arm-portion for relative displacement arcuately about said loop-portion in order to adjust the amount by which the door may open.

3. A hinge-pin doorstop as defined in claim 2, wherein each of said bumper-members is mounted on one end of an elongated screw threaded to the corresponding one of said arm-portions with its longitudinal axis extending tangentially of said hinge pin.
