Description

[Detailed description of the invention] The present invention includes a clip made of a filamentous body such as a metal wire and having a fixed part and a free end for carrying. The present invention relates to a structure for attaching a clip to a writing instrument which is fixed to a clip attachment site.

Since the clips provided on the main body or cap of a writing instrument are important in terms of their function and aesthetics, various types of clips have been proposed and improved over the years. However, in the case of a clip made of an elastic metal wire having the same cross section, although the clip itself is easy to form, it is difficult to securely fix the clip to the main body or cap of a writing instrument.

The present invention has been devised in order to solve the above-mentioned drawbacks in view of the current situation. In a writing instrument comprising a clip, the fixed part of the clip is fixed to a clip attachment part on the body of the writing instrument, a cap, etc., wherein the free end of the clip for carrying is connected to a pair of arm parts substantially parallel to each other. and a connecting bending part that connects one ends of these arms to each other, and the fixing part of the clip includes a pair of bending parts that extend from the other end of the pair of arms substantially perpendicularly to these arms. A first fitting portion and a pair of second fitting portions extending from each free end of the pair of first fitting portions substantially orthogonally to the first fitting portions, forming a substantially L-shape. and a first fitting recess into which the pair of first fitting portions fit and a second fitting recess into which the pair of second fitting portions fit are formed. This relates to a structure for attaching a clip to a writing instrument, characterized in that the retainer is fitted and fixed by press-fitting, adhesive, etc. into a fitting opening formed in the clip attaching part. be. According to the present invention constructed in this way, the clip can be reliably fixed to the main body, cap, etc. of a writing instrument by using parts with a simple structure and by a simple operation.

Next, one embodiment of the present invention will be explained with reference to the drawings.
In this embodiment, the clip is fixed to the head of the cap of the writing instrument.

The clip 1 used in this embodiment is constructed by cutting a metal wire of a predetermined length from a coil of metal wire and bending it into a predetermined shape. That is, the metal wire has a predetermined elasticity, strength, and coefficient of friction, and approximately at the center thereof.
It is bent 180 degrees to form a connecting bent part 2 in the central part. In addition, since the pair of straight portions connected to both ends of the bent portion 2 are bent in the same direction at approximately right angles near their upper ends, there is a gap between the bent portions 3a, 3b and the connecting bent portion 2. A pair of arm portions 4a, 4b are formed substantially parallel to each other. Further, since the metal wire is bent at a substantially right angle in the same direction between the bent portions 3a, 3b and the pair of tips 5a, 5b, the bent portions 6a, 6b
First fitting portions 7a, 7b which are substantially parallel to each other are formed between the bent portions 3a, 3b, and second fitting portions 7a, 7b are formed between the bent portions 6a, 6b and the tips 5a, 5b. 8a and 8b are formed. In this case, the direction in which the second fitting portions 8a, 8b extend from the bent portions 6a, 6b and the direction in which the arm portions 4a, 4b extend from the bent portions 3a, 3
The directions extending from b are the same direction, and both are substantially parallel to each other.

Note that the pair of arm portions 4a, 4b and the connecting bending portion 2
has an elongated U-shape as a whole and constitutes the free end of the clip 1 for carrying. In the vicinity of the lower ends of the pair of arm parts 4a, 4b, locking bent parts 9a, 9b are formed by bending these arm parts 4a, 4b into a substantially V-shape or a substantially U-shape. Also, the first fitting part 7a and the second fitting part 8a
The first fitting portion 7b and the second fitting portion 8b each constitute a substantially L-shaped fixing piece, and the fixing portion of the clip 1 is constituted by these pair of fixing pieces.

Further, the cap 11 used in this embodiment is provided with a fitting opening 12 dug into a substantially rectangular parallelepiped shape on the circumferential side of its head.

Further, the fastener 21 used in this embodiment is configured to have substantially the same shape as the fitting opening 12. Therefore, the retainer 21 has a substantially rectangular parallelepiped shape, and only its front surface is a cylindrical surface having approximately the same curvature as the side surface of the cap 11. And the retainer 21
A pair of first fitting recesses 22a and 22b for fitting the first fitting portions 7a and 7b are formed on the upper surface of the recess 22a and 22b so as to extend substantially parallel to each other. Further, on the back side of the retainer 21, second fitting portions 8a, 8b are provided.
A pair of second fitting recesses 23 for fitting the
a and 23b are formed to extend substantially parallel to each other. In this embodiment, the first fitting recesses 22a and 22b are formed over the entire length of the upper surface of the locking element 21 in the front-rear direction, and the second fitting recesses 23a and 23b are formed on the back surface of the locking element 21. It is formed over the entire length in the vertical direction. These second fitting recesses 23a, 23b are connected to the first fitting recesses 22a, 22b at the upper end of the back surface of the retainer 21.
For this reason, the first fitting recess 22
a, the second fitting recess 23a, and the first fitting recess 2
2b and the second fitting recess 23b each have a substantially L-shape as a whole.

Next, the operation of attaching the clip 1 to the cap 11 will be explained. First, the first fitting parts 7a, 7b and the second fitting parts 8a, 8b of the clip 1 are connected to the first fitting recesses 22a, 22b of the clip 21. and second
Fit into the fitting recesses 23a and 23b, respectively. Next, while maintaining these fitted states, the retainer 21 is inserted into the fitting opening 12 of the cap 11.
to fit. In this case, the retainer 21 may be press-fitted and fixed into the fitting opening 12, or both may be bonded together with an adhesive. Note that when the retainer 21 is fitted and fixed in the fitting opening 12, the first fitting portion 7a,
7b is the upper wall surface 13 of the fitting hole 12 and the retainer 21
A first fitting recess 22a formed on the upper surface of the
It is held between the peripheral wall surface of 22b. At the same time, the second fitting portions 8a and 8b are connected to the fitting opening 12.
It is held between the side wall surface 14 of the retainer 21 and the peripheral wall surfaces of the second fitting recesses 23a and 23b formed on the back surface of the retainer 21. Therefore, the fixing portion of the clip 1 is securely fixed to the head of the cap 11.

The cap 11 thus obtained has an elongated U-shaped free carrying end extending downwardly along its circumferential surface. A pair of locking bent portions 9a and 9b formed on a pair of arm portions 4a and 4b constituting the free end portion for carrying are attached to the cap 1.
1, or are slightly separated from it. Therefore, when a piece to be held (not shown) such as pocket fabric is inserted relatively between the free end for carrying and the circumferential side of the cap 11, the free end for carrying will separate from the circumferential side of the cap 11. It is elastically displaced and then tries to elastically restore itself. Therefore, the clamped piece is elastically clamped between the carrying free end (particularly the locking bent parts 9a and 9b) and the circumferential surface of the cap 11, so that the cap 11 and the entire writing instrument are thus clamped. It is held by a clamping piece.

Although one embodiment of the present invention has been described above, the present invention is by no means limited to the above-mentioned embodiment, and various modifications and variations can be made within the scope of the above-mentioned utility model registration claims. Needless to say, changes are possible.

As described above, the present invention includes fitting the first and second fitting parts constituting the substantially L-shaped fixing part into the first and second fitting recesses of the retainer, respectively, and
Since the retainer is fitted and fixed in the fitting hole, the fixing portion of the clip can be very reliably fixed to the clip attachment portion of the writing instrument in which the fitting hole is formed.

A carrying free end portion having a pair of arms substantially parallel to each other and a connecting bending portion connecting one end of these arm portions to each other; and a substantially L-shaped fixed portion connected to the carrying free end portion. and a clip made of a filament, a fitting opening is provided at the clip attachment portion of the writing instrument, and a first and a second
Since it is only necessary to prepare a locking element in which a fitting recess is formed, it is easy to manufacture the necessary parts, and the structure thereof is also extremely simple.

Furthermore, since it is only necessary to fit the first and second fitting parts into the corresponding first and second fitting recesses, and then to fit and fix the retainer into the fitting opening, it is possible to attach the clip. It is also extremely easy to operate.

In addition, by changing the shape and dimensions of the retainer, clip, and fitting hole, the required clip can be attached to the main body or cap of various writing instruments, making it suitable for mass production. Not only is it useful, but it is also highly versatile.
