Description

[Detailed Description of the Invention] The present invention relates to a pencil sharpener and a pencil holder as an attachment thereof.

It has been known that a pencil holder can be attached to the case of a pencil sharpener in a detachable manner.
As disclosed in Japanese Utility Model Publication No. 47-42842, a pencil holder is detachably attached to a main case made of a paramagnetic material using magnetic force,
Therefore, not only does the total weight of the pencil sharpener itself increase dramatically, but as synthetic resin materials are widely used today and the pursuit of making it lighter and more compact, it is natural that the main body case and pencil holder of the pencil sharpener will also have to increase. It is molded from synthetic resin and cannot be attached magnetically as in the past.

In view of the above-mentioned problems, the present invention aims to provide a simple mechanism for attaching and detaching a pencil holder, regardless of the material of the case of the main body of a pencil sharpener.

Its structure is that the main case of the pencil sharpener is made of a synthetic resin material, the pencil holder is also made of a synthetic resin material, and a recess is formed on one side of the pencil holder to accommodate a part of the main case. The recess is provided with an elastic piece having a locking claw at its tip that elastically engages with a through hole drilled in the main body case.

Therefore, with this configuration, the pencil holder can be attached to the pencil sharpener body case with one touch, without using the conventional attachment method using magnetic force.
Moreover, since it is an integrally molded product made of synthetic resin, it is possible to provide a lightweight and compact pencil sharpener with a removable pencil holder, which improves usability and design effect.

Hereinafter, a best embodiment of the present invention will be described in detail with reference to the drawings.

Reference numeral 1 denotes a main body case of a rechargeable pencil sharpener according to an embodiment of the present invention, which is composed of a cutting chamber 2 having a substantially cylindrical shape and a driving mechanism chamber 3 having a substantially rectangular parallelepiped shape. The cutting chamber 2 has a scrap tray 4 that is slidably attached and detached on one side thereof, and a pencil insertion hole 6 is provided in the upper cover 5 of the cutting chamber 3.
It has a cutting blade (not shown) that rotates coaxially with the blade. Further, a display window 7 for a cutting completion indicator lamp is attached to the upper surface of the drive mechanism chamber 3, and an operation knob 8 for a charging plug attached to one side so as to be freely accessible from the drive mechanism chamber 3 is attached to its elongated hole 15 for guiding. A through hole 9 for inserting a hanging cord is located above the through hole 9,
Drill 9. Moreover, inside the drive mechanism chamber 3,
An electric motor (not shown) serving as a rotational drive source for the cutting blade and its speed reduction mechanism (not shown) are attached, and a rechargeable battery (not shown) and a rectifier (not shown) are installed.
It consists of

On one side of the drive mechanism chamber 3, a pencil holder 10 having substantially the same shape as the cutting chamber 2 is located at a position substantially symmetrical to the cutting chamber 2. The pencil holder 10 has a substantially cylindrical shape without a lid, and a recess 11 for housing one side of the drive mechanism chamber 3 is formed in a part of the pencil holder 10 . A pair of elastic pieces 13, 13 having engagement claws 12, 12 facing each other at their tips are integrally formed in the recess 11. It is inserted against the elastic force of the pieces 13, 13 and is locked on the inner surface of the rib 14 between the through holes 9, 9.

The pencil sharpener having the above structure is usually placed on a desk, and if the pencil is inserted into the pencil insertion hole 6 while the pencil is placed on the desk, the pencil will be cut. At this time, the pencil holder 10 is positioned on one side of the main body case 1 so that the through holes 9, 9 and the engaging claws 12, 12 are aligned with each other, and moved in the horizontal direction. 1
2 are pushed apart by the ribs 14, and when the pencil holder 10 is further moved toward the main body case 1, the engaging claws 12, 12 are pushed apart by the ribs 14.
is clamped and fixed, and the attachment of the pencil holder 10 is completed. When the pencil holder 10 is attached to the main body case 1, the stability is very good. That is, there is a space in the cutting chamber 2 opposite to the direction of rotation of the cutting blade about the axis of the pencil insertion hole 6. However, due to the weight of the pencil holder 10 and the weight of the pencils leaning against it, the frictional resistance between the pencil holder 10 and the desk top is increased to prevent the drive mechanism chamber 3 from rotating. Further, since the guide slot 15 of the operating knob 8 is covered by the recess 11 of the pencil holder 10, it is possible to prevent the knob 8 from being operated by mistake, and to prevent dust from entering the slot 14.

When carrying, the pencil holder can be easily removed by pulling the main case 1 and the pencil holder 10 in opposite directions.The pencil holder is lightweight for carrying, and can be carried by simply passing a hanging string through the through holes 9, 9. This makes it even easier to hold.

Charging is also the same as when carrying, and the pencil holder 10 is removed from the main case 1, the plug 8 is taken out from the main case 1, and charging is performed.

As described above, the present invention makes it possible to provide a lightweight pencil sharpener that is inexpensive, easy to operate, and has excellent operability by elastically engaging a pencil holder with a synthetic resin pencil sharpener in a detachable manner without using magnetic force. have an effect.
