Description

Eraser Case {Eraser Case}

The present invention relates to an eraser case, and more particularly, to an eraser raising device for easily storing the eraser and exposing the eraser as the eraser is worn out.

An eraser is a tool that is mainly composed of rubber or plastic, such as a pencil, which erases marks caused by graphite.

It is made by taking advantage of the excellent element properties of rubber. It is mainly used to erase pictures and texts drawn using pencil or sharp. It is easy to buy on the market and is often used to erase ink. Among the pencils, there may be an eraser behind, so that it can be used conveniently.

Most erasers on the market are made out of paper and plastic on the outside, so remove the outer wrapping to replace the worn out parts. In addition, the last remaining eraser is hard to grip by hand, hard to store in a small volume, and easily lost due to increasing use.

Korean Utility Model Application No. 20-2005-0020695 discloses an eraser remover for easily and easily removing residues generated after use of an eraser and an eraser remover for preventing the eraser from moving when a worn eraser is slightly removed from the case There is no means for raising the eraser step by step in the eraser case.

Korean Patent Application No. 10-2010-0052582 is a pencil barrier for protecting a pencil which can be replaced by an eraser. The pencil barrier is manufactured in the form of a barrel to protect the pencil lead. In order to prevent the pencil from falling out, And it takes a protruded shape to perform a role. Thus, there is a problem that similar function is performed in the storage effect, but a rising function that pushes forward for convenient use as much as a shortened length can not be achieved by using a pencil.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems, and it is an object of the present invention to provide an eraser case which can be used until the eraser is pushed up according to the usage state.

The present invention also provides a means for providing an eraser lifting power to the case side with an external force.

Another object of the present invention is to provide means for adjusting the degree of elevation on the other side of the case so that the eraser can be moved at regular intervals.

In order to solve the above problems, the present invention provides an eraser case comprising: a case; A support for supporting the eraser; A lifting device located on one side of the support capable of lifting the support; An auxiliary lifting device located on a lower surface of the case that assists the lifting of the support; The lifting and lowering device is rotatable through a predetermined portion of a side surface of the case by a circular belt structure. The lifting device exposed to the outside is pushed by hand And the auxiliary lifting device may be composed of an upper surface of the lower portion of the case and a spring which is an elastic material coupled to the lower surface of the support, And the other surface is formed with an engaging portion which can engage with the engaging groove. The engaging portion is connected to the lower portion by an elastic material, and when a force is applied When it is descended below the surface, when the force is removed, it returns to the original state, Provide that the features are easily eraser case.

In addition, the present invention provides an eraser case characterized in that the coupling hole has a curved shape of a straight line toward the rising side of the support base in an upward direction of the support base, and the opposite side is a right angle form for preventing the support base from moving downward when the eraser is used do.

According to the present invention as described above, external contamination is blocked and the eraser can be pushed up to the end according to the use state, thereby enabling the use of the eraser to last.

In addition, the present invention is characterized by providing an elevating power to elevate the eraser using an external force.

Further, the present invention is characterized in that the eraser elevation can be moved at regular intervals.

1 is a conceptual diagram of an eraser case according to the present invention.
2 is a conceptual view of an internal structure of the eraser case of the present invention.
3 is a view showing a state of coupling between a support and a support of the present invention.
4 is a view showing the movement of the support member of the present invention.

Hereinafter, preferred embodiments of the present invention will be described in detail. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted so as to avoid obscuring the subject matter of the present invention.

As used herein, the terms " about, " " substantially, " " etc. ", when used to refer to a manufacturing or material tolerance inherent in the stated sense, Accurate or absolute numbers are used to help prevent unauthorized exploitation by unauthorized intruders of the referenced disclosure.

FIG. 1 is a conceptual view of an eraser case of the present invention, and FIG. 2 is a conceptual view of an internal structure.

More specifically, the present invention relates to an eraser case 1, comprising: a case 100; A support 130 for supporting the eraser; A lifting device (110) located on one side of the support base (130) capable of lifting the support base (130); An auxiliary lifting device (120) located on a lower surface of the case to assist in lifting the support; And an engagement groove 135 located on the other side for movement of the support base at regular intervals

The lifting and lowering device 110 may be made of a silicone or rubber material having a good folding force so that the lifting device 110 can be rotated by passing through a certain portion of the upper and lower sides of the case at one side of the case, have. That is, by using the principle of rotating the conveyor belt, it is possible to move the circular belt by frictional force mainly by using the finger ground plane. In addition to the use of rubber or concrete cone, which is a material of good frictional force, it is also possible to improve the finger and the folding force by imparting unevenness to the shape of the round belt.

The auxiliary lifting device 120 may be formed of a spring, which is an elastic material coupled to the upper surface of the lower portion of the case and the lower surface of the support. Since the auxiliary lifting device can not smoothly raise the eraser by only the lifting device, a considerable force may be required. Therefore, a spring having good elasticity may be lifted from the support base 130 coupled to the inside of the case of the lifting device 110, This is to give synergy effect.

One side of the support is vertically connected to the circular belt of the lift device, and serves as a base through which the eraser can move. On the other side, a coupling hole 133 is formed which can engage with the coupling groove. (133) is connected to the lower part by a spring, which is an elastic member (131), and when the force is applied, it is lowered below the surface.

The supporting device is required to be able to stop the elastic force of the auxiliary lifting device to stop the supporting device to hold the eraser in a state in which the eraser is partially lifted by pushing up the eraser.

Therefore, the coupling hole 133 is coupled to the coupling groove 135, thereby preventing the support pin from being raised any more. If it is necessary to raise the coupling hole, the coupling hole is moved and joined to the coupling groove adjacent to the upper side as shown in FIG.

However, the coupling hole 133 is formed in a curved line shape in an upward direction so that it can be easily moved in the ascending direction of the support member, and the opposite side is a right angle shape for preventing the support member from moving downward when the eraser is used.

In the rectangular shape, when the eraser is used, the eraser is pressed to receive a force toward the support. At this time, if the coupling hole has the same stream shape as the rising side, the coupling hole can be easily separated from the coupling hole and can be moved downward, so that the shape of the coupling hole may be different when the eraser is used.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventions. It will be clear to those who have knowledge of.
