Abstract

PURPOSE: An eraser for a propelling pencil having a rotating holder case is provided to facilitate the safety handling of the eraser for the propelling pencil, and to promote the easy detachment of an eraser holder. CONSTITUTION: The bolt typed eraser holder(10) formed with a screw thread(7,7a) on the inner surface thereof is mounted on the distal end of an eraser(6) of the propelling pencil. A short bar(9) is projected from the end of the eraser holder toward the inner side of the erase holder. The projected short bars serve to prevent the eraser from being unintentionally rotated within the eraser holder. A case(2) defined in the propelling pencil for receiving a lead for the propelling pencil is provided with a nut tunnel(8) having a screw thread, thereby the eraser mounted in the eraser holder is easily separated with the propelling pencil under the interaction of screw threads between the nut tunnel and the eraser holder. Also, the insertion length of the eraser is easily adjusted according to the interaction of the screw threads without using a separate tool.

Description

회전식 홀더 케이스를 구비한 샤프펜슬 지우개{Sharp pencil eraser with revolving holder case}Sharp pencil eraser with revolving holder case

본 발명은 샤프펜슬의 지우개 한쪽 끝단부에 안, 밖에 나사산(7,7a)으로 구성된 지우개 홀더를 구성한후, 샤프심 케이스(2) 내부에 나사산(8)을 형성, 지우개 홀더가 샤프심 케이스의 내부 통로를 지우개의 사용용도 쪽으로 회전 시켜서 꺼내어 사용할수 있는 방법을 제공 하는 것이다.According to the present invention, an eraser holder composed of threads 7 and 7a is formed at one end of an eraser of a mechanical pencil, and a screw thread 8 is formed inside the sharp shim case 2, and the eraser holder is an internal passage of the sharp shim case. It is to provide a way to take out by rotating it to the use of the eraser.

샤프 펜슬의 지우개를 사용자의 용도에따라 회전 시켜 꺼내어 안전하고 편리하게 쓸수 있는 장치를 구성함을 목적으로 한다.The purpose of the device is to construct a device that can be used safely and conveniently by rotating the eraser of the pencil according to the user's purpose.

본 발명은 샤프 펜슬의 지우개를 꺼내어 쓰기위한 장치에 관한 것으로서, 보다 상세하게는 회전시켜서 꺼내어 사용할수있는 샤프펜슬 지우개 장치에 관한것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an apparatus for drawing out an eraser of a sharp pencil, and more particularly, to a mechanical pencil eraser device which can be rotated and used out.

종래의 샤프펜슬의 지우개 주변 구조는 제1도와 같다. 또한 샤프펜슬의 지우개 홀더는 제1도의 (3,4)이다.The structure around the eraser of the conventional mechanical pencil is shown in FIG. The eraser holder of the mechanical pencil is (3, 4) in FIG.

따라서 지우개가 닳아서 꺼내어 사용할때, 지우개를 사용 용도만큼 꺼내기 위해서는 손톱이나 별도의 도구로 (3,4)부분을 열어서 지우개를 꺼내고 다시 (3,4)를 조여서 고정한후 사용한다.Therefore, when the eraser is worn out and used, to remove the eraser as much as the intended use, open the (3, 4) part with a fingernail or a separate tool, take out the eraser, and fix it by tightening (3, 4) again.

그러나 상기의 지우개 홀더의 (3,4)를 열거나 조여서 닫기 위해서는 손톱에 무리가 가고, 또한 파손이 될수도 있으며, 별도의 도구를 활용하여 열고 닫아야 하는 불편이 있다.However, in order to open or tighten the eraser holder (3,4) to close or close the nails, it may be damaged, and there is an inconvenience to open and close using a separate tool.

상기의 불편을 해소하고자 본 발명의 주된 목적은 샤프펜슬의 지우개의 한쪽 끝단부에 나사산을 가진 볼트 홀더(10)를 구성하고 샤프 펜슬 케이스(2)의 내부에 지우개 홀더가 회전하면서 지우개의 사용 방향쪽으로 회전하며 나아갈수 있는 나사산(8) 너트 터널을 구성하는 장치를 구성하여 지우개가 그 구성장치의 사용으로 인해 안전하고 편리하게 사용될수 있는 장치를 제공하는데 있다.The main object of the present invention to solve the above inconvenience is to configure the bolt holder 10 having a screw thread at one end of the eraser of the mechanical pencil, and the direction of use of the eraser while rotating the eraser holder in the mechanical pencil case (2) It is to provide a device that constitutes a thread (8) nut tunnel that can be rotated toward and away from it so that the eraser can be used safely and conveniently due to the use of the device.

제1도는 종래의 샤프펜슬의 지우개 부분의 확대 단면도.1 is an enlarged cross-sectional view of an eraser portion of a conventional mechanical pencil.

제2도는 본 발명의 실시예에 따른 샤프 펜슬의 지우개 부분의 확대 단면도.2 is an enlarged cross-sectional view of an eraser portion of a sharp pencil according to an embodiment of the present invention.

제3도는 도2의 (10)부분의 확대 단면도.3 is an enlarged cross-sectional view of the portion (10) of FIG.
