Description

심 교체연필의 후부투관(後部套管)Posterior Peripheral Tube of Shim Replacement Pencil

제1도는 본원 고안의 단면 측면도.1 is a cross-sectional side view of the present invention.

제2도는 후부투관의 사시도.2 is a perspective view of the posterior mandibular tube.

제3도는 후부투관을 고무지우개로서 이용한 일례를 나타낸 사시도.3 is a perspective view showing an example of using the rear end pipe as a rubber eraser.

* 도면의 주요부분에 대한 부호의 설명* Explanation of symbols for main parts of the drawings

(1) : 연필축, (2) : 단심,(1): pencil axis, (2): single core,

(3) : 유지편, (7) : 후부투관,(3): maintenance piece, (7): posterior osmotic tube,

(9) : 가는 구경부(9): fine aperture

본원 고안은 긴 1개의 합성수지제 연필축의 내부에 갈아 끼우는데 사용하는 단심(短芯)을 여러개 순서적으로 배열하여 이루어지는 심을 갈아 끼우는 연필에 있어서, 단심의 귀환 방지작용을 갖는 후부투관(後部套管)을 지우개로서도 이용할 수 있도록 한 것이다.The present invention devises a rear tube which has a single core return prevention action in a core replaceable pencil formed by arranging a plurality of single cores used in order to change the inside of one long plastic pencil shaft. ) Can also be used as an eraser.

다음에, 첨부도면에 의거하여 본원 고안의 실시예를 설명하면,Next, an embodiment of the present invention will be described based on the accompanying drawings.

(1)은 합성수지제의 긴 1개의 중공(中空)연필축이며, 전방이 실제의 연필의 형상에 닮게하여 약간 죄여서 가늘게 되어있다, (2)는 갈아끼우는 데 사용하는 단심이며, 유지편(3)의 선단에 짧은 심(4)이 고착되어있다. 유지편(3)의 후부에는 구멍(5)이 뚫려 있고, 유지편(3)의 구멍(5)에는 순서적으로 계속되어 있는 다음의 심(4)이 끼워 넣어지도록 되어 있다. (6)은 캡이며, 이킵은 종래의 것과 달라서 축(1)의 장공(1')을 유지편(3)과 함께 진행하도록 되어 있다. 상기 구성의 연필에 있어서 본원 고안의 특징은 연필축(1)의 후부투관(7)을 합성고무 또는 천연고무에 폴리에틸렌과 같은 합성수지를 혼합하여 이루어진 가요성고무재료를 사용한 것이며, 후부투관(7)중앙의 삽입구(8)의 바깥쪽을 상기 단심(2)의 유지편의 외경과 대응시키는 동시에 삽입구(8)의 내측을 엷게하고 가는 구경부(9)로 한 것이다. 그리고 삽입구(8)의 외주의 피착부(10)에 홈(11)을 설치하여 연필축 후단의 소단부(12)의 돌조(13)에 탄성적으로 끼워 맞추어 피착한 것이다.(1) is a long hollow hollow pencil shaft made of synthetic resin, and the front is similar to the shape of an actual pencil and is slightly tightened and thinned. (2) is a single core used for changing, and a holding piece ( A short shim 4 is fixed to the tip of 3). A hole 5 is drilled in the rear portion of the holding piece 3, and the next shim 4 which is continued in sequence is fitted into the hole 5 of the holding piece 3. Reference numeral 6 denotes a cap, which is different from the conventional one, so that the long hole 1 'of the shaft 1 moves along with the holding piece 3. The feature of the present invention in the pencil of the above configuration is that the flexible rubber material made by mixing the synthetic rubber or natural rubber with the rear end pipe (7) of the pencil shaft (1), the rear end pipe (7) The outer side of the center insertion hole 8 is made to correspond with the outer diameter of the holding piece of the said core 2, and the inside of the insertion hole 8 is made thin and the thin part 9 is made. And the groove 11 is provided in the to-be-adhered part 10 of the outer periphery of the insertion hole 8, and it fits and fits elastically to the protrusion 13 of the small end part 12 of the pencil shaft rear end.

본원 고안은 상기와 같은 구성을 가지며, 연필축(1)에 대하여 단심(2)을 순차적으로 교체하여서 사용하는 것은 종래와 전적으로 마찬가지지만, 후부 투관(7)이 폴리에틸렌과 같은 합성수지제를 혼성과 고무재료로써 성형한 것이므로 후부투관의 중앙의 삽입구(8)에서 삽입된 단심은 내측의 가는 구경(9)을 탄성적으로 확대시키면서 나아가며, 가는 구경(9)을 통과하여 버리면 구경(9)이 축소되어 단심이 필압(筆壓)에 의하여 되돌아가는 것을 방지한다. 한편, 후부투관은 상기와 같은 고무재료로 성형되어 있기 때문에 지우개로서 그대로 이용할 수 있으므로 종래의 것과 비교해서 매우 편리하다.The present invention has the configuration as described above, the use of the single core (2) in order to sequentially replace the pencil shaft (1) is entirely the same as in the prior art, the rear bushing (7) is a synthetic resin such as polyethylene mixed with rubber Since the molded part is formed of a material, the single core inserted in the insertion hole 8 in the center of the posterior tube proceeds while elastically expanding the inner narrow aperture 9, and when passed through the narrow aperture 9, the aperture 9 is reduced. The single core is prevented from returning by the pen pressure. On the other hand, since the rear end pipe is molded from the above rubber material, it can be used as an eraser as it is, which is very convenient compared with the conventional one.
