Hair clip with a ring spring

Abstract

A hair clip including a left clamping portion, a right clamping portion, a positioning pin, and a ring spring. The internal side of the left and right clamping portions is provided with a pair of projecting ears near the center of the upper portion for a pivotal connection. The projecting ears include pin holes for the insertion of the positioning pin. A groove is formed slightly above the projecting ears of the left and right clamping portions, respectively, such that the ring spring is positioned against the external side of the grooves when the ring spring is forced in an open position. In this way, a resilient force created by the ring spring may act upon both of the left and right clamping portions, thereby forming a proper inward clamping force.

Description

BACKGROUND OF THE INVENTION[0001]1. Fields of the Invention[0002]The present invention relates to an improved hair clip structure, and more particularly to a structure that provides an even and stable clamping force. Meanwhile, a convenient, durable and appealing effect of the hair clip can be achieved.[0003]2. Description of the Related Art[0004]As shown in FIG. 6, a popular hair clip of the prior art includes two clamping portions 10, 11 with corresponding projecting ears 12 for receiving a conventional torsional spring 13. A clamping force created by two legs 14, 15 of the torsional spring 13 acts on the clamping portions 10, 11. Of course, the above-mentioned conventional structure provides many economic and convenient advantages. However, the torsional spring 13 has restricted service life. Meanwhile, many problems like loosening, inclination and slip-away of the hair clip are often caused in use either by insufficient clamping force of the torsional spring 13 or by uneven forc...

AI Technical Summary

Benefits of technology

[0006]It is a primary object of the invention to provide a hair clip structure that employs a ring spring to completely change the shape of the conventional elastic piece, thereby providing a completely new appearance different from the conventional design. In addition to the convenient assembly advantage, a wider force-applying surface is available. In this way, the problems of the conventional hair clips can be avoided. Moreover, the service life the hair clip can be prolonged.

Problems solved by technology

However, the torsional spring 13 has restricted service life.

Meanwhile, many problems like loosening, inclination and slip-away of the hair clip are often caused in use either by insufficient clamping force of the torsional spring 13 or by uneven force applied to the legs 14, 15 that is attributed to many factors like improper production process, material, assembly, operation, or unexpected external force application.
