Description

[Detailed description of the invention] In a writing instrument holder in which a large number of partition walls or tunnels are provided on the upper surface of the substrate in parallel with the direction in which the writing instrument is inserted, a spring is attached to each inner surface of the partition wall as a mechanism to prevent the inserted writing instrument from coming out. There are several types of tunnels that are known, such as one with a tunnel bottom and one with a part of the bottom of the tunnel bulged so that the space between the top and bottom of the tunnel is dimensioned so that it comes into close contact with a writing instrument, but both have complicated structures. Particularly in the latter case, there are problems in that unless the diameter of the writing instrument matches the inner diameter of the bulge in the tunnel, it cannot reliably perform its extraction prevention function.

The purpose of the present invention is to provide a writing instrument holder for pens equipped with a retaining device that solves these problems. Attachment parts for a pencil case are provided at both ends of one side edge of a substrate made of an elastic and flexible synthetic resin material, and an external part is provided on the top surface of this board at a location close to the above-mentioned retaining part. The gist is that a tapered protrusion that slopes upward in the direction is integrally provided.

In the illustrated embodiment, a board 1 is integrally molded from a soft synthetic resin material and has a pencil retaining part 2 having a shape in which a number of tunnels are lined up on the top surface, and the board 1 is attached to both ends of one side of the board 1. Engagement notches 4, 4 are provided, and one side of the board 1 is once squeezed and bent from both sides using fingers to connect the engagement notches 4, 4 to hook-shaped protrusions 5, 5 provided oppositely on the upper surface of the middle plate 10 described below. The holder 3 of the present invention is attached to the middle plate 10 by engaging the holder 3 by releasing it, and the pencil inserted in the stopper part 2 can be removed from the upper surface of the board 1 at a location close to the stopper part 2. A tapered protrusion 6 that slopes upward toward the outside is provided to prevent the protrusion from coming out.

In addition, FIG. 2 shows a case body 7, a first lid plate 8 that covers the case body, a second lid plate 9 that covers the center notch of the first lid plate 8, and a shaft bearing on the base end of the second lid plate 9. This figure shows the state in which the above-mentioned holder 3 of the present invention is fixed to the middle plate 10 of a pencil case composed of the middle plate 10.

As mentioned above, in the present invention, a tapered protrusion that slopes upward toward the outside is integrally provided on the upper surface of the board near the above-mentioned stop, so that it can be inserted into the stop. A portion of the lower side of the writing instrument presses against the tapered protrusion and a portion of the upper side presses against the upper edge of the opening of the retaining portion to prevent the writing instrument from being accidentally pulled out, In particular, since this protrusion is formed on the outside of the stop, it is different from the known method in which a clamping spring is provided on the inner surface of the partition wall or a part of the bottom of the tunnel-like stop is bulged. The writing instrument removal prevention device of the present invention has an extremely simple structure and is easy to manufacture.
In addition, in this invention, the writing instrument is prevented from coming off at the upper edge of the tapered protrusion and the opening of the stopper as described above, so it is not strictly restricted by the diameter of the writing instrument and has some flexibility. Correspondingly, the protrusion can be prevented from coming off, and this not only has the effect of fully achieving the above-mentioned object of the present invention, but also allows the protrusion to be secured to the substrate. Since the protrusion is integrally provided with the protrusion, it has excellent effects such as being easier to provide and being more durable than a means of attaching separately constituted members.
