Abstract

A plastic clip for use clothes such as a sudpender clip, kimono, or clohespin, has an all plastic three-part design incorporating an over center clipping action dependent upon the resiliency of plastic materials, and incorporates no metallic spring. An upper clipping member has a spindle plate established between side walls, and a pair of recess bearings on inner faces of the side walls. A lower clipping member has a ditch like bearing which engages the spindle plate of the upper clipping member, a projection which is narrower than protuberances formed on the sides of the projection, and an elastic tongue prepared on a central portion just under the projection which extends upward. The third portion of the clip is an operation stick having a box with outer walls which is established to be inserted between upper clipping member side walls and the lower clipping member projection. The operation stick member also has a pair of actuation expansions on the out side of the box outer wall while both inner sides of the box have a pair of engaging dents into which protuberances of the lower clipping member are fitted in. A pressure plate of the operation stick member is established hehind the center of the actuator expansions and a slit-like belt insertion is prepared at the rear end of the operation.

Claims

1. A plastic clip having an upper clipping member, a lower clipping member, and an operation stick member, the clip comprising:

an upper clipping member having an upper substrate, on a rear portion of which a mouth is built in a square shape, a pair of side walls formed in both sides of the mouth, on the front and lower side of each wall a spindle plate in an arcuate shape being bridged between the side walls while a pair of recess bearings which accept the operation member are formed on an inside surface of the walls at a distance from the spindle plate;

a lower clipping member having a lower substrate, wherein its rear portion is formed narrower in size than its front portion so that this narrower rear portion is insertable between a front end of the mouth and the spindle plate, having a ditch-shaped bearing being formed to be freely movable over the spindle plate on the rear and lower portion of the upper substrate, having a projection formed in its rear end with a pair of protuberances established on both sides of the lower substrate, said projection extending towards the rear end of the mouth and being narrower than the rear portion of the lower substrate, and having an elastic tongue extending upward between legs a pair of a U-letter shaped opening for separating front portions of the upper and lower clipping members and

an operation stick member having an operation substrate, having on one end a box defined by a pair of outer side walls with a thickness adapted to be inserted between a rear end of the mouth and a rear end of the projection and also adapted to be insertable between inner surface of the upper clipping member side walls and outer surface of the lower clipping member projection from the lower side of the mouth, having a pair of actuation expansions which freely engage with the pair of recess bearings on the outer surface of a pair of outer side walls, having a pair of engaging dents which are fitted with the protuberances formed on a lower and inner surface of outer side walls, having a pressure plate which contacts on upper surface of the projection being established behind the center of the actuation expansions in the box, and having a slit shaped belt insertion drilled on another end of the operation substrate.

2. A clip according to claim 1, wherein a recess is formed in a center of a projection at the end of the lower clipping member and a pressure plate with a slope established in an upper and inner surface of the box built into the operation stick member, and the pressure plate has its width adapted to be fitted into the recess.

3. A clip according to claim 1, wherein the upper clipping member is constructed as one integral body.

4. A clip according to claim 1, wherein the lower clipping member is constructed as one integral body.

5. A clip according to claim 1, wherein the operation stick member is constructed as one integral body.
