Description

[Detailed description of the invention] (Field of industrial application) The present invention is a clip for writing instruments, more specifically, it creates a sense of luxury and solidity, and allows easy attachment to the barrel or cap barrel of the writing instrument. This invention relates to a writing instrument clip that has improved mass productivity as much as possible.

(Prior art) Some of the clips for writing instruments that have been known in the past include those that are made by appropriately bending a thin plate made of stainless steel or the like, or by pressing, etc. These basically lacked a sense of luxury and solidity, and had the disadvantage that they were particularly unsuitable as clips for writing instruments in high-class products. Therefore, some attempts have been made to solve the above-mentioned problem by using a thick plate-like material such as die-cast zinc, which does not have elasticity, but this method does not have elasticity, and As a result, the ability to attach to a pocket etc. is lost, and other elastic members such as coiled springs or leaf springs are required. Alternatively, when storing and arranging the cap in the cap barrel, the assembly work becomes complicated or troublesome, and the assembly work becomes difficult.
The problem was that the cost was high and it was not suitable for mass production. (Purpose of the invention) The present invention was devised in view of this situation, and by devising a non-elastic metal clip body and a mounting member with appropriate elasticity, it can be used as a writing instrument clip. To provide a clip for a writing instrument that gives off a sense of luxury and solidity, and which can also be easily attached to the barrel or cap barrel of the writing instrument.

(Example) Hereinafter, the present invention will be described in detail based on an example shown in the accompanying drawings.

Reference numeral 1 refers to a thick plate made of zinc, aluminum, brass, or an alloy thereof, or obtained by cutting various metals, which itself does not have elasticity, in other words, does not bend. It is a metal clip body having a shape, and the back surface of the clip body 1 is provided with a holding protrusion 2 and a concave groove 4 having flanges 3, 3 on both side edges and opening at the rear end. Approximately at the center of the bottom of the concave groove 4, a locking protrusion 5 is integrally provided that protrudes slightly toward the front of the clip body 1 without any difference in level.

Reference numeral 6 denotes a mounting member made of stainless steel or various spring steel materials having appropriate elasticity for attaching the clip body 1 to the barrel or cap barrel, and the mounting piece 7 of the mounting member 6 is attached to the clip body 1. The dimensions are set in advance so that it can be press-fitted into the groove 4 of the main body 1, and the mounting piece 7 has a locking protrusion 5 in the groove 4 when the mounting member 6 is press-fitted into the groove 4. A locking hole 8 for locking is bored. When attaching the attachment member 6 to the clip body 1, press the attachment piece 7 of the attachment member 6 into the rear end of the groove 4 of the clip body 1, and press it forward, so that the tip of the attachment piece 7 is engaged. The locking hole 8 passes over the locking protrusion 5 and locks onto the locking protrusion 5, so that the attachment of both is completed reliably and easily.

When actually attaching the writing instrument clip obtained in this way to a barrel or cap barrel, for example, as shown in FIG. It is easy to assemble by inserting the shaft tube or the cap tube 10 and the tail cap 11, and as in the past, coiled springs, leaf springs, etc. are stored and arranged in the shaft tube. It does not require any complicated work.
Similarly, the clip body 1 can be attached to the attachment member 6 after only the attachment member 6 is attached to the cap barrel 10 or the like.

In addition, in the above embodiment, as the locking protrusion,
Although the description has been made using a so-called triangular shape that gradually rises toward the front of the clip main body, the present invention is not limited to this, and for example, a plurality of hemispherical shapes may be provided to serve as a locking protrusion. In this case, it is necessary to provide a corresponding number of locking holes in the mounting piece. Furthermore, various modes other than the above-mentioned embodiments can be adopted when attaching to the shaft tube or cap tube.

(Effects of the invention) As described above, the present invention provides a groove made of non-elastic metal, which has a concave groove with flanges on both side edges on the back side, and a locking protrusion protruding from the bottom of the groove. It consists of a clip body and a mounting member having a locking hole that is press-fitted into the groove and is locked to the locking protrusion, so it has a luxurious and solid feel as a writing instrument clip body. It is possible to use a thick plate that is necessary and sufficient to create a sense of style, and it is also possible to form it into various shapes in terms of appearance. Since there is no need for the complicated work of storing and arranging leaf springs and the like in the shaft tube or cap tube, the cost can be reduced and mass productivity can be improved as much as possible. Furthermore, the clip body and the attachment member can be attached by simply sliding them relative to each other. This point applies not only when attaching both parts in advance and then attaching the whole thing to a cap barrel, but also when attaching the mounting member to the cap barrel first and then attaching the clip body. To,
Greater flexibility in easy installation. Here, if you first attach the attachment member to the cap tube, etc., and then attach the clip body, the locking protrusion on the clip body should be used to attach the attachment member to the cap tube. It is extremely easy to work with because it is not affected by the pressure applied to the cylinder, etc., and even if a wide variety of clip bodies are prepared in response to diversification, the final stage is the installation. It is also possible to attach a suitably selected clip body to the member.

In the present invention, the aesthetic appearance may be further enhanced by applying a suitable pattern to the surface of the clip body.
