Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a clip that allows smooth opening and closing operations.

Conventionally, as shown in FIG. 1 or 2, a plate body is pivoted on the body b side and the cover c side from a support shaft a, and has a torsion spring d fitted on the support shaft a. For example, in the case of a clip made of synthetic resin that opens and closes one end, a hook-shaped bent part e is provided to bend the tips of the leg parts at both ends led out from the torsion spring d inward as shown in Fig. 1. The one that is in contact with the inner surface of the body b side and the cover c side, or as shown in Fig. 2, with the tip of the leg part d left open,
It is known that the spring is brought into contact with both the spring side and the cover c side, but the former has the disadvantage of increasing manufacturing costs because an additional bending process is added to the legs cut out in the spring manufacturing drawing. was. In the latter case, the tip of the uncut leg is the body b.
Moreover, the clip has the disadvantage that it bites into the cover c, causing problems such as creating a creak when opening and closing the clip, and also impairs the appearance.

The present invention has been made in order to eliminate the above-mentioned drawbacks, and uses the legs of a torsion coil spring in an open state. To provide a clip that can be obtained at low cost by providing a supporting part that supports the distal end of the leg part in a loose state while being in contact with the clip, and also enables smooth opening and closing operations.

Hereinafter, the details of the present invention will be explained with reference to FIG. 3 for an embodiment. Reference numeral 1 designates a clip body consisting of a pair of body part 2 and cover part 3, each of which is provided with a bearing part 5, 5 having a spindle insertion hole 4, through which a spindle 6 inserted into the insertion hole 4 is inserted. are combined. Reference numeral 7 denotes a torsion coil spring, which has a winding part 8 that is inserted into the support shaft 6, and a pair of legs 9, 9 extending from the winding part 8, which can be attached to the body part 2 and the cover part in a cut-off state. The clip body 1 is supported on the inside of the clip body 3 and elastically urges the clip body 1. Reference numeral 10 denotes an operating portion of the clip body 1, which has a recess 11 provided on the inner surface of the clip body 1 and a support portion 12, for example, in the shape of a protrusion, which is erected from within the recess 11.
2 is adapted to come into contact with the side surface of the leg portion 9.
Therefore, the tip of the leg 9 is supported within the recess 11 in a manner that it is free from the bottom surface of the clip body 1.

As mentioned above, since the torsion coil spring 7 is supported by the support part 12 of the action part 10 that comes into contact with the side surface of the leg part 9 that extends uncut from the winding part 8, the tip of the leg part 9 The leg portions are separated from the clip body 1, so that they do not dig into the clip body 1 even when the clip is opened or closed, so that smooth operation is performed, and the leg portions 9 do not require any processing. Workability is also improved.

As described in detail above, the present invention comprises a pair of clip bodies that are combined via a support shaft, a winding part that is inserted into the support shaft, and a leg part that extends in an uncut manner from this winding part. a torsion coil spring that acts on the clip body to elastically bias the clip body; and a support part that is provided on the acting part of the clip body and comes into contact with the side surface of the leg tip part and supports the leg tip in a state where it is free from the clip body. This clip improves the workability of manufacturing torsion coil springs, making it possible to obtain them at low cost, and eliminates problems with opening and closing operations caused by the legs of the spring biting into the clip body, making it possible to operate smoothly. It has many advantages.
