Abstract
A molded safety pin having an elongated base portion with extensions at both ends is described. At the first extension a hinged connection provides the means for biasing the pin portion at the juncture of the means for anchoring the pin and the base portion. At the second extension a detent structure provides the means for holding the pin portion securely when the safety pin is in a closed position while permitting convenient manual release of the pin when required. Additionally a simplified injection mold for fabricating the safety pin is described.
Claims8
A molded safety pin of the character described, comprising:
- (a) a base portion being elongated in length relative to the width of the base portion, the base portion having an upper surface and a lower surface;
- (b) a first extension at one end of the base portion;
- (c) means for providing a hinged connection between the first extension and the base portion;
- (d) the first extension being thicker than the base portion, with a part of the first extension being normally below the lower surface of the base portion when the safety pin is in an open position;
- (e) the first extension having a pin portion anchored therein, the pin portion extending substantially in a linear direction away from the first extension and the base portion when the safety pin is in an open position;
- (f) the pin portion being readily biased back over the upper surface of the base portion by means of the hinged connection between the first extension and the base portion;
- (g) a second extension comprising a detent extending in a reverse loop from the opposite end of the base portion for retaining the pin portion in a closed position when the pin portion is moved beneath the detent;
- (h) the base portion also including as a molded part thereof a wing-like pin guiding structure extending transversely from the upper surface of the base portion at opposite sides of the detent to partly enclose and overlie the detent.
