Abstract

A mechanical sharp pencil having several lead storing chambers is provided to store the sufficient amount of leads and to prevent at least two leads from moving into a lead fixing unit by charging the lead fixing unit with one lead. In a mechanical sharp pencil, a lead supply chamber(200) stores leads in a lead fixing unit(100). An opened lower end of the lead supply chamber is connected to the lead fixing unit. The lead supply chamber has a lead insert hole formed at the side to receive the lead from the outside. A lead supplementing unit surrounds the lateral side of the lead supply chamber, turns for the lead supply chamber, and has a plurality of partitions(310) formed at the inner side in a longitudinal direction of the lead supply chamber.

Description

Mechanical pencil with several sharp core storage rooms {MECHANICAL PBMCIL WITH PARTTTIONED LEADS ROOM}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mechanical pencil having a plurality of mechanical pencil storage chambers, and more particularly, to a mechanical pencil capable of selectively using the mechanical pencils stored in each mechanical pencil storage chamber by a user's operation. A mechanical pencil is a writing tool made by inserting a thin shim and turning or pressing the tip of the shaft to push the nib out little by little.

1 is an exploded perspective view showing an example of a conventional mechanical pencil. As shown in FIG. 1, there is a sharp shim fixing part 10 for fixing a shim used in the mechanical pencil, and a sharp shim supplying chamber connected to the sharp shim fixing part 10 to supply the sharp shim to the sharp shim fixing part 10. 20) There is. The sharp shim supply chamber 20 is configured to store the sharp shims therein. The sharp shims in the sharp shim supply chamber 20 are loaded into the sharp shim fixing part 10 one by one by gravity and a user's pressing or rotating operation. The sharp shim fixing part 10 pushes the loaded sharp shim little by little by pressing or rotating the user, and the sharp shim fixing part 10 is attached to the mechanical pencil.

Fix the position of one sharp shim.

The sharp pencil body 30 is coupled to the circumference of the sharp shim supply chamber 20 so that the user can comfortably hold the mechanical pencil, and the upper end of the sharp shim supply chamber 20 prevents the sharp shim stored in the sharp shim supply chamber 20 from escaping. , User press operation

Faucet 50 may be combined to make it convenient. Such a conventional mechanical pencil has the following problems.

1 is an exploded perspective view showing an example of a conventional mechanical pencil.

As shown in FIG. 1, there is a sharp shim fixing part 10 for fixing a shim used in the mechanical pencil, and a sharp shim supplying chamber connected to the sharp shim fixing part 10 to supply the sharp shim to the sharp shim fixing part 10. 20) There is. The sharp shim supply chamber 20 is configured to store the sharp shims therein. Sharp shim in the sharp shim supply chamber 20

The sharp shim fixing part 10 is loaded one by one by pressing or rotating operation.

The sharp shim fixing part 10 pushes the loaded sharp shim little by little by the user's pressing or rotation operation, and newly fixes the position of the sharp shim with respect to the sharp pencil.

The sharp pencil body 30 is coupled to the circumference of the sharp shim supply chamber 20 so that the user can comfortably hold the mechanical pencil, and the upper end of the sharp shim supply chamber 20 prevents the sharp shim stored in the sharp shim supply chamber 20 from escaping. Faucet 50 is coupled to facilitate the user's pressing operation.

The conventional mechanical pencil has the following problems.

In order to eliminate the inconvenience of carrying the sharp shim container separately or the discomfort of frequently changing the sharp shim in the sharp shim supply chamber 20, if too many sharp shims are put in the sharp shim supply chamber 20, the sharp shim fixing portion (only one sharp shim should be loaded) The sharpness is very often concentrated in 10). Since the sharp shim fixing part 10 is designed so that only one sharp shim is loaded, when two or more sharp shims enter the driveway of the sharp shim fixing part 10, the operation of the mechanical pencil stops. In order to disassemble the sharp shim fixing portion 10 to block the access path of the sharp shim fixing portion 10

Drilling is very cumbersome and cumbersome. In addition, frequent failures take valuable time and effort from the user. Such a repair is impossible even with the mechanical pencil, that is, the user can not disassemble the sharp shim fixing part 10

In the case of using a mechanical pencil that cannot penetrate the access road of the blocked sharp core fixed part 10, the mechanical pencil must be discarded.

The present invention is to solve the problems of the mechanical pencil as described above, the object of providing a mechanical pencil without a large number of sharp cores are concentrated in the sharp core fixing section 100, while a sufficient amount of sharp shim is stored. It is done.

According to the present invention, while a sufficient amount of sharp shim is stored, too many sharp shims are concentrated in the sharp shim government 100.

A mechanical pencil is provided without a problem.

According to one embodiment of the present invention for achieving the object as described above, having a shape capable of storing the sharp core inside the sharp core fixing portion that the sharp core is fixed, the open bottom is connected to the sharp core fixing part, It has a shape surrounding the side of the sharp shim supply chamber and the sharp shim supply chamber in which the sharp shim inlet hole can be introduced from the outside, and is formed to rotate with respect to the sharp shim supply chamber, the inner surface of the plurality of partitions of the sharp shim supply chamber There is provided a mechanical pencil including a sharp shim replenishment formed in the longitudinal direction. The partition may be formed to block the sharp shim inlet hole according to the rotation of the sharp shim replenishing unit with respect to the sharp shim supply chamber. Hereinafter, specific embodiments of the present invention will be described with reference to the accompanying drawings. Like reference numerals in the accompanying drawings denote like elements.

2 is an exploded perspective view illustrating a mechanical pencil according to an embodiment of the present invention. In FIG. 5, the sharp seam replenishment unit 300 is partially visible.

As shown in FIG. 2, the sharp pencil according to the present embodiment has a shape capable of storing the sharp shim inside the sharp shim fixing part 100 in which the sharp shim is fixed, and the lower end of the sharp shim supply chamber connected to the sharp shim fixing part 100. And a sharp seam replenishment unit 300 having a shape surrounding the side of the sharp seam supply chamber 200. The sharp core supply chamber 200 may have a long shape so as to store the sharp core therein. Beam in Sharp Shim Supply Room 200

The lower end of the sharp seam supply chamber 200 is opened and connected to the sharp seam fixing unit 100 so that the sharp seam can be supplied to the sharp seam fixing unit 100. The sharp shim stored in the sharp shim supply chamber 200 may be supplied to the sharp shim fixing part 100 by gravity.
