Pencil lead protection for wood pencils {PENCIL LEAD PROTECTION FOR WOOD PENCIL}

The present invention relates to a pencil lead protector for a wooden pencil that is opened so that the pencil lead is exposed when the pencil is used, and the pencil lead is not exposed to the outside during the standby state or storage of the pencil.

In general, a pencil is a writing instrument in which a pencil lead is inserted inside a body made of wood, and the body is used by cutting the body so that the pencil lead of the part to be used is exposed.

Such a pencil has a problem in that the pencil lead is frequently damaged because the pencil lead is always exposed to the outside without a separate lid during standby or storage. In addition, since the pencil lead is sharpened in a sharp shape, there is a problem in that various injuries such as being stabbed in the hand occur.

In order to solve this problem, Patent Document 1 proposes a separate lid that can be mounted on the pencil lead, but in Patent Document 1, the lid has to be removed every time a pencil is used, and the lid has to be installed every time after use. In addition to this, there was a problem in that the use efficiency was insufficient due to frequent loss of the separated lid.

Patent Document 1: Republic of Korea Utility Model Publication No. 20-2010-0004749 "Pencil lead damage prevention lid"

The present invention is intended to solve the above problems, and even if the user does not separately attach or remove the lid each time, by putting the protective equipment in and out through a simple operation of the user, the pencil lead is exposed when using the pencil, The task is to prevent the pencil lead from being exposed to the outside when the pencil is waiting for use or stored.

And, once the protective equipment as described above is installed, it is not separated until all the pencil leads are used, and it moves according to the length of the pencil body and makes it possible to perform the above function.

The present invention makes a pencil lead protector for a wooden pencil comprising a cylindrical body in which a pencil is inserted in the center and a guard plate that enters and exits from the inside of the body as a means of solving the problem. More specifically, a pencil lead protector for a wooden pencil capable of selectively exposing or closing the pencil lead as the protective plate enters and exits in the direction of the exposed pencil lead according to the user's selection from the inside of the protective gear body as a means of solving the problem.

According to the present invention, even if the user does not separately mount or remove the lid each time, the user puts in and out the protective equipment through a simple operation of the user, so that the pencil lead is exposed when the pencil is used, and the pencil lead is exposed to the outside when the pencil is in use or storage. By not preventing it, there is an effect that can prevent damage to the pencil lead and various injuries caused by the pencil lead.

In addition, once the protective equipment as described above is installed, it is not separated until all the pencil leads are used, and it moves according to the length of the pencil body and has the effect of performing the above function.

3 and 4 are perspective views for explaining the operation of the pencil lead protector for a wooden pencil according to the present invention;
5 is a perspective view for explaining another operation example of a pencil lead protector for a wooden pencil according to the present invention;

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, this is for the purpose of describing in detail enough that a person of ordinary skill in the art to which the present invention pertains can easily implement the invention, and this does not mean that the technical spirit and scope of the present invention are limited thereto.

The present invention relates to a protective device for protecting a pencil lead exposed in a wooden pencil, and as shown in FIGS. 1, 2, 3 and 4 , it is configured to include a body 10 and a protective plate 20 .

The body 10 has a pencil inserted in the central portion, and accommodates the guard plate 20 to be described later so as to be able to enter and exit. In addition, the shape of the body 10 is preferably made of a cylindrical shape, but it is not necessarily limited to the above shape, and various shapes can be applied in consideration of the shape of a pencil or ease of use. For example, in consideration of the ease of gripping the pencil, the body 10 may be manufactured in a cylindrical shape inclined downward in the direction of the exposed pencil lead.

On the other hand, an insertion hole 10a into which a pencil is inserted is formed in the central portion of the body 10, a receiving portion 10b for accommodating the protective plate 20 is formed therein, and a switch 30 to be described later is formed at the outer end. An exposed opening 10c is formed.

The protective plate 20 selectively exposes or closes the pencil lead while entering and exiting the inside of the body 10 . That is, according to the user's selection, it may come out from the receiving portion 10b inside the body 10 in the direction of the exposed pencil lead to wrap and close the pencil lead, or enter the exposed pencil lead in the opposite direction to expose the pencil lead.

More specifically, the switch 30 has one end coupled to the protective plate 20 inside the body 10 , and the other end exposed to the outside of the body 10 . That is, when the switch 30 is pushed in the direction of the exposed pencil lead to slide, the protective plate 20 connected thereto comes out in the direction of the exposed pencil lead to wrap and close the pencil lead, and when the switch 30 is pulled in the opposite direction to the exposed pencil lead and slides, the connected The guard plate 20 enters in the opposite direction to the exposed pencil lead to expose the pencil lead.

On the other hand, if you want to fix the entrance and exit state of the guard plate 20, for example, as shown in FIG. After forming (10b'), when the switch 30 is rotated and inserted in the direction of the corresponding receiving part (10b') in a state of entering and leaving, the switch 30 does not slide in the exposed longitudinal direction of the pencil lead or in the opposite direction. As it is fixed, the protection plate 20 coupled to the switch 30 also has a corresponding input/exit state.

That is, in the present invention, even if the user does not separately mount or remove the lid each time, by using a protective device that enters and leaves through a simple operation of the user, the pencil lead is opened to expose the pencil when the pencil is used, and the pencil lead is in the standby state or storage of the pencil. This can be prevented from being exposed to the outside.

And once the protective equipment as described above is mounted, it is not separated until all the pencil leads are used, and it moves according to the length of the pencil body 10 and can perform the above function.

Although some embodiments have been described above by way of example, it is obvious to those skilled in the art that the present invention may be embodied in various other forms without departing from the spirit and scope thereof. Accordingly, the above-described embodiments are to be regarded as illustrative rather than restrictive, and all embodiments within the scope of the appended claims and their equivalents will be included within the scope of the present invention.
