Description

[Detailed description of the invention] The present invention relates to a clip device for a writing instrument with a cap. This invention relates to a clip device for a writing instrument with a cap, which causes the clip to protrude from the outer peripheral surface of the cap (when the cap is fixed to the front part of the writing instrument).

Conventionally, clips that are fixed or inserted in a state where the clip is always protruding have a poor feel when writing, and the problem with sharp pencils is that the width of the handwriting changes due to one side of the lead slipping. It had

In this way, varying the outward protrusion of the clip, which always protrudes, when writing and when carrying the paper, has an extremely large functional effect, and for this purpose, it is necessary to manipulate the clip. A clip device for retracting and retracting the clip is also known, but in order to retract and retract the clip, operations such as pressing the clip itself in the axial direction or sliding it in the longitudinal direction are required, and although it is not preferable in terms of operability. Nakatsuta. Furthermore, Utility Model Application No. 58833/1984 is also known as a device that attempts to eliminate the troublesome operation of ejecting and ejecting by automatically retracting the clip when attaching and removing the cap to a writing instrument, but this device In this case, a spring base with a spring piece is inserted and fixed into the cap, and the spring piece is configured to elastically repel the clip outward, so the method of ejecting the clip is unreasonable, and when the clip is ejected, The problem remains that sufficient clamping force cannot be imparted to the clip.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a clip device for a writing instrument with a cap, which allows the clip to easily and quickly come out and disappear when the cap is attached to and removed from the writing instrument, and which can apply sufficient clamping force to the protruding clip. It is in.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The drawings show an embodiment of the present invention, and in this embodiment, a nozzle-type sharp pencil was used as the writing instrument.

A indicates a cap, and reference numeral 1 is a cap barrel made of resin or metal. In the rear of the cap barrel 1, a pressing body 2 is provided between the inner surface of the rear end of the cap barrel 1. A resilient member 3 made of a coil spring, a magnet, etc. is placed so as to bias it forward. Reference numeral 4 is a support column, and the support column 4
One end is inserted through a ring 7 which is biased forward by an elastic member 6 such as a coil spring provided between the front end surface of the inner protrusion 5 of the cap barrel 1, and the middle part is inserted into the ring 7. is inserted into the through hole 8 described later,
The other end is inserted into a base 14 of a clip 10, which will be described later. Reference numeral 8 is a through hole bored behind a groove 9 provided in the longitudinal direction of the outer periphery of the cap barrel 1 and having substantially the same width as the arm portion 11 of the clip 10, which will be described later. Reference numeral 10 is a clip made of resin or metal that is inserted into the groove 9, and the clip 10 has a clamping protrusion 12 on the inner surface of the tip of the arm 11.
a base 14 on which an elastic body 13 made of a coil spring, a plate spring, etc. is disposed so as to be connected to the other end of the support column 4, which has a resilient force that constantly pushes the clamping protrusion 12 inward; have.

Reference numeral B indicates a knock-type sharpening pencil, but since it is a normal sharpening pencil, the details are omitted, but 15 is a barrel, 16 is a knob cap, and 17 is a stepped portion.

Next, the operation of the present invention will be explained with reference to FIGS. 4 and 5.

When the cap A is fixed to the front part of the sharp pencil B, the stepped portion 17 of the barrel 15 presses the front end surface of the ring 7, and the ring 7 moves rearward against the elastic force of the elastic member 6. . Due to this rearward movement of the ring 7, the support column 4 swings about the through hole 8 as a fulcrum, so that the base 14 of the clip 10 moves outward against the elastic force of the elastic body 13. The gripping protrusion 12 protrudes and rides on the outer peripheral surface of the cap barrel 1. Along with this operation, the protrusion 18 provided on the inner surface of the tip end of the cap barrel 1 moves into the recess 1 provided on the outer peripheral surface of the shaft barrel 15.
9, and cap A and sharp pencil B are fixed together. (See Figure 4) When the cap A is fixed to the rear of the sharp pencil B, the knock cap 16 presses the front end surface of the pressing body 2, so that the pressing body 2 resists the elastic force of the resilient member 3. It moves rearward and protrudes from the rear end surface of the cap barrel 1. Along with this operation, the protrusion 18 of the cap barrel 1 fits into the recess 19 of the shaft barrel 1, and the cap A and sharp pencil B are fixedly attached. When attaching the cap A to the rear of the sharp pencil B in this manner, the ring 7 is not acted upon from the outside, so the clip 10 is recessed into the groove 9 and is approximately flush with the outer peripheral surface of the cap barrel 1. keep it. (See Figure 5) For convenience, this invention has been shown using a sharp pencil as a writing instrument, but by making customary design changes, this invention can also be applied to writing instruments such as ballpoint pens and fountain pens that use water-based or oil-based inks. Various methods can be adopted.

As described above, the present invention has the practical effect of allowing the clip to be easily and quickly removed when attaching and detaching the cap to a writing instrument, and to provide sufficient clamping force to the protruding clip. .

In the example shown in FIG. 1, an eraser may be installed at the rear of the pressing body 2, or other suitable means such as screwing may be used as a means for attaching the cap and the writing instrument, in addition to fitting. However, this does not alter the gist of the present invention in any way.
