Description

  The present invention relates to a writing instrument clip mounting structure.

  The function of the writing instrument clip is to prevent rolling when the writing instrument is placed on a desk, etc., and when the cloth such as a pocket is inserted between the clip and the surface of the shaft tube, the cloth is firmly held between the surface of the clip and the shaft tube. In addition, it has a function of preventing a dropout from a pocket or the like when being carried.

  The latter function can be obtained by making the clip springy. To make the clip springy, lifting the clip piece extending in the longitudinal direction of the clip causes the clip piece to bend and return to its original shape. Of the structure in which the force of the clip piece is springy, and the spring is elastic when the fixed portion is urged by the spring and the entire clip is lifted away from the surface of the shaft body or cap cylinder. There is a structure that uses the force of the clip as a spring. Of course, in the structure in which the clip itself bends, there is a problem that when the thickness of the clip piece is increased, the clip piece is not bent, and when the clip piece is thinned, the clip piece is broken. In order to obtain the desired clip clamping force, it is necessary to design the clip shape, thickness, etc., but it is difficult to obtain the desired clip clamping force with a desired clip shape. is there. On the other hand, the structure in which the entire clip is lifted away from the surface of the shaft body or the cap tube is more complicated in the structure for attaching the clip to the shaft body or the cap tube than the above, and the number of parts is also increased. Although there is a problem, there is an advantage that a desired clip holding force can be easily obtained with a clip having a desired shape, and it is particularly employed in expensive writing instruments such as a fountain pen.

  A structure for attaching a clip for a writing instrument in which the entire clip is lifted in a direction away from the surface of the shaft or the cap cylinder is well known in Japanese Utility Model Publication No. 62-75982. A fixing part is inserted into a square hole or notch provided in the vicinity of the head end of the shaft body or cap cylinder, and the head plug member and shaft cylinder or cap cylinder arranged at the head end of the shaft body or cap cylinder With the inner member that can be screwed to the head plug member inserted inside, the head portion formed on either the head plug member or the inner member is inserted into the mounting hole of the fixing portion of the clip, and the head plug member and the inner member A structure in which a clip is disposed between the head plug member and the inner member, and a spring (coil spring) is arranged so as to bias the box-shaped portion of the fixed portion of the clip toward the head plug member. It is. The spring is to press the ball part of the clip against the side surface of the shaft cylinder in order to firmly hold the object to be clamped between the ball part provided on the clip and the side surface of the shaft cylinder. belongs to.

  Therefore, as the shape of the clip for the writing instrument in the structure as described above, since the clip itself does not need to bend, it is possible to adopt a thick clip in order to create a high-class feeling, but the material cost is high. There exist problems, such as becoming high and the difficulty of the process to a desired shape. However, it would look bad if a thin clip was attached to an expensive writing instrument. Therefore, as a clip for a writing instrument that looks thick and can be formed in various shapes, side wall pieces are provided on both side edges of a thin plate-like clip piece as disclosed in Japanese Utility Model Publication No. 58-110486. Structural clips have been proposed and attached to various writing instruments.

  As described above, the fixing part is inserted into the square hole or notch provided near the head end of the shaft body or the cap tube, and the head plug member and the shaft arranged at the head end of the shaft body or the cap tube. With the inner member that can be screwed to the head plug member inserted inside the tube or the cap tube, the shaft formed on either the head plug member or the inner member is inserted into the mounting hole of the clip fixing portion and the head In the writing instrument clip in the mounting structure in which the clip is disposed between the head plug member and the inner member by screwing the stopper member and the inner member, the bent portion or the fixing portion of the clip that can be visually recognized particularly in an expensive writing instrument. Also, it is necessary to provide side wall pieces on both side edges so as to have the same thickness.

However, it has been found that there is a problem that when the clip for a writing instrument is actually attached to a cap, the clip is liable to run out. As a result of pursuing the cause, in the mounting structure, the shaft portion formed on either the head plug member or the inner member is fixed to the lateral movement of the clip so as to be inserted into the mounting hole of the fixing portion of the clip. The side wall piece in the part comes into contact with the shaft part, but the side wall piece is bent because the thickness of the side wall piece is not thick because of the processing problem of the clip. The present invention has been reached.
