Description

[Detailed Description of the Invention] The present invention relates to an eraser holder that allows the eraser to be freely taken in and out of the barrel.

Conventionally, as shown in Japanese Utility Model Application Publication No. 52-126951, a slider with an eraser attached is fitted into a pipe having a slit with a number of concave portions in sequence on the side, and a knob integrated with the slider is protruded from the slit. A so-called retractable eraser holder is known, in which a predetermined amount of eraser is protruded from the tip of a pipe by being held in the hand and semi-engaged with the concave portion of the slit in sequence, but these eraser holders are designed to protrude the eraser in stages. The device generates an engaging noise when it is ejected and stored, and is not suitable for use in places where silence is particularly required, such as libraries or examination halls, as it may disturb others.

In this invention, if the knob is pressed as it is, it will move in a semi-engaged state, and if the pressing part provided on the knob is pressed downward, it will move in a non-engaged state, that is, in a state where no engagement sound is generated. It is something.

Next, an embodiment of the present invention shown in the accompanying drawings will be described in detail. Reference numeral 1 denotes a shaft cylinder having a slit 1a formed in the axial direction, and a large number of recesses 1b sequentially formed on both sides of the slit 1a. Reference numeral 2 denotes a slider that moves within the barrel 1, and has an eraser 3 press-fitted and fixed at its tip, and holes 2a and 2b formed in its upper surface. 4 is a mountain-shaped leaf spring having a top portion 4a;
The top part 4a is fitted into the hole 2a and protrudes upward, and is fitted into the recess 1b from below. 5 is a knob, and a leg 5a protruding from the lower surface is press-fitted from above through a slit 1a into a hole 2b of a slider 2 fitted into a shaft cylinder 1. Reference numeral 6 denotes a tongue-shaped pressing portion provided by cutting out the front portion of the knob 5 in a substantially 〓 shape, and an upward protrusion 6c and a lower portion facing the top portion 4a of the leaf spring 4 are provided at the end of the thin base portion 6b. It has a facing protrusion 6a.

Note that the downward protrusion 6a of the pressing part 6 is not particularly limited as long as it has a position and shape that allows it to slide within the slit 1a during pressing.

Next, the operation of the present invention will be explained.

Due to the above-described structure of the present invention, when the eraser 3 is protruded and retracted, and when the knob 5 is moved forward or backward along the slit 1a, the top 4a of the leaf spring 4 in the slider 2 touches both sides of the slit 1a. The slider 2 is in a state of being fitted into the successively provided recesses 1b (semi-engaged state, producing an engagement sound), and the slider 2 is interlocked with the knob 5, and the eraser 3 fixed to the tip of the slider 2 makes an engagement sound. While generating the shaft cylinder 1
It protrudes from the tip or is housed in the shaft tube 1. Next, as shown in FIG. 3, when moving the knob 5 forward or backward along the slit 1a while pressing downward the upward protrusion 6c of the pressing part 6 provided on the knob 5, the leaf spring in the slider 2 4 is pressed downward by the downward protrusion 6a of the pressing part 6, and the recessed part 1
The slider 2 moves in conjunction with the knob 5, and the eraser 3 fixed to the tip of the slider 2 generates an engagement sound. It protrudes from the tip of the shaft cylinder 1 or is housed within the shaft cylinder 1.

Note that the pressing part 6 in the present invention is not limited to the embodiment, and if necessary, by pressing, the top part 4a of the leaf spring 4 is released from fitting into the recess 1b, and when pressed, the pressing part 6 can be pressed. Any material may be used as long as it does not interfere with the sliding movement of 5.

As described above, the eraser holder of the present invention is capable of selectively protruding the eraser as needed and preventing the generation of engagement noise when storing it by providing a pressing part on the knob of the conventional retractable eraser holder. It is an excellent one.
