Abstract
A pin for securing objects together by piercing or frictional engagement. The inventive device includes a safety pin having an end cap and a pivoting member releasable therefrom which can be piercingly engaged to an object. A paper clip extends from the end cap and cooperates with the safety pin so as to frictionally engage and retain planar objects therebetween.
Claims6
A paper clip safety pin comprising:
- a safety pin member for piercingly engaging a plurality of objects so as to secure the objects together, the safety pin member comprises an end cap having a receiving slot directed thereinto;
- a fixed member extending from the end cap and continuing into a spring;
- a pivoting member extending from the spring and being biased thereby into the open position, the pivoting member being shaped so as to define a piercing tip, with the pivoting member being positionable against a force of the spring into the receiving slot of the end cap;
- a paper clip extending from the safety pin member and cooperating therewith so as to frictionally engage and retain a plurality of planar objects between the paper clip and a portion of the safety pin member, the paper clip comprises a first member projecting from the end cap, the first member continuing an integral bend;
- a second member projecting from the integral bend and towards the end cap, the second member being coupled to the end cap and cooperating with the first member and the integral bend so as to define an elongated loop which cooperates with the safety pin member so as to frictionally engage and retain planar objects therebetween.
