Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a structure for attaching a clamping piece to a writing instrument clip.

(Prior art and its problems) A clip obtained by molding a metal plate material has a clamping function using its own elasticity, and the front end of the clip has a front part. A clamping piece made of resin is attached to make the clamping operation easier by floating it, and also to give a design and decorative effect.

The above-mentioned structure for attaching the clip to the clip includes a clip that has a hole that can be fitted onto the front of the clip and is fixed using adhesive, and a clip that has serrations formed on both sides of the clip. It is known that a clamping piece similar to the one described above is press-fitted into the bracket and fixed, but in the former case, there are problems such as leakage of adhesive and a lack of fixation durability. However, in the latter case, a considerable pressing force is required to press-fit and fix the clamping piece, and there is a problem that play is likely to occur due to variations in the press-fitting direction.

(Purpose of the invention) The present invention was devised in view of the above-mentioned conventional problems, and it is an object of the present invention to provide a structure for attaching a clamp holder to a writing instrument clip, which allows the clamp holder to be attached to the clip easily and reliably.

(Structure of the invention) Hereinafter, the invention will be described in detail based on embodiments shown in the accompanying drawings.

In FIGS. 1 and 2, reference numeral 1 is a plate-shaped clip made of metal whose rear end is attached to the shaft tube 2. It has a curved portion 3. 4 has an inner shape that is approximately the same as the outer shape of the front end of the clip 1 including the bent portion 3, and has a substantially U-shaped longitudinal section, and has a step portion 6 on the lower inner surface that can engage with the end surface 5 of the bent portion 3. It is a resin clamping piece.

When attaching the clamping piece 4 to the clip 1, first insert the front end of the clip 1 from behind the clamping piece 4. Although the clamping pieces 4 are pushed apart against their own elasticity due to the insertion, the end face 5 of the bent portion 3
When it meets the stepped portion 6, it closes again due to its own elasticity, and the clamping piece 4 engages the stepped portion 6 with the end surface 5 of the bent portion 3 while keeping its inner surface in close contact with the front end of the clip 1. It will be attached to clip 1 in this state.

Even with such a structure, it is possible to hold the clamp piece 4 with the clip 1.
However, if consideration is given to preventing the clamping piece 4 from moving laterally or rattling due to impact, etc., ribs 7 can be formed on the inner wall of the clamping piece 4 as shown in Fig. 3. At the same time, a recess 8 into which the rib 7 can fit is provided at the front end of the clip 1, and a rib 9 is formed in the stepped portion 6 of the clamping piece 4, as shown in FIG. A fitting recess 10 may be provided in the bent portion 5 of the clip 1, or a clamping piece 4 may be provided as shown in FIG.
The clip 1 may be provided with a protrusion 11 on the inner surface of its upper part and a hole 12 into which the protrusion 11 can fit.

(Effects of the Invention) As described above, the present invention includes a clip having a bent portion at the front end, and a step having an inner shape approximately the same as the outer shape of the front end of the clip, and capable of engaging with the end surface of the bent portion. Since it consists of a clamping piece that has an inner surface of the clamping piece, the clamping piece can be securely attached with an extremely simple installation operation of simply inserting the front end of the clip into the clamping piece and engaging the stepped part of the clamping piece with the end surface of the bent part. Can be attached to a clip.
