손목시계 용두(龍頭)의 구조The structure of the watch crown

첨부된 도면은 본 발명의 한 실시예의 종단면도The accompanying drawings are longitudinal cross-sectional views of one embodiment of the present invention.

본 발명은 손목시계의 용두부분에 있어서, 용두의 내주와 권진(卷眞) 파이프외주에 형성된 요부에 2개의 패킹을 내설한후, 그 패킹사이에 윤활제를 충전한 손목시계방수 용두의 구조에 관한 것이다.The present invention relates to the structure of the watch waterproof crown in which the lugs of the crown are formed on the inner periphery of the crown and the outer periphery of the rolled pipe and filled with lubricant therebetween. will be.

종래, 손목시계방수 용두의 방수구조는 보통의 손목시계에 적용되는 것과, 특히 잠수용 손목시계에 적용되는 완전방수 타입의 것이 있다.Conventionally, the waterproof structure of the watch waterproof crown is applied to a normal watch, and in particular, a waterproof type that is applied to a diving watch.

전자의 구조는, 원통상으로 형성한 권진파이프에 용두를 감삽하고, 이 용두와 권진파이프의 사이에 방수용 패킹을 취부함으로서 빗물에 손목시계가 노출되는 경우나 물을 취급하는 경우등과 같이 비교적 소량의 물에 대한 방수성을 유지하고 있는데 지나지 않는다.The former structure has a relatively small amount, such as when a watch is exposed to rainwater or when water is handled by subtracting the crown into a cylindrically formed winding pipe and installing a waterproof packing between the crown and the winding pipe. It's water resistant, but it's nothing more.

또 후자의 경우는, 전자의 종래예와 비교하면, 용두와 권진파이프사이에 극히 많은 방수용 패킹을 설치하거나, 용두를 작동하지 않는 평상시, 권진의 회전에 의한 물의 유입읕 방지하기 위해 용두와 권진파이프사이에 쇄정기구를 설치하였다.In the latter case, in comparison with the former example, in order to prevent the inflow of water due to the rotation of the kinematics, there are very many waterproof packings installed between the crowns and the wound pipes, or when the crowns are not operated. A locking mechanism was installed in between.

이 경우, 상술한 보통용의 용두에 비교하여 용두와 권진파이프사이에 방수패킹의 마찰력이 극히 크게되어 용두를 회전시키기가 어렵게되고, 또 용두부분의 구조가 복잡하게 되기때문에, 제작이 어렵게 될뿐 아니라, 조립능률이 저하된다.In this case, compared to the general-purpose crown mentioned above, the frictional force of the waterproof seal between the crown and the winding pipe becomes extremely large, making it difficult to rotate the crown, and the structure of the crown part is complicated, thus making the production difficult. However, the assembly efficiency is lowered.

본 발명은 이와같은 종래의 결정을 감안하여 창안된 것으로, 방수성이 좋고, 용두의 회전이 원활한 손목시계 용두의 구조를 얻을 목적으로 안출한 것이다.This invention was devised in view of such a conventional crystal, and it was devised for the purpose of obtaining the structure of the watch crown which is water-resistant and smoothly rotates the crown.

이하 본 발명을 구체적으로 표시한 첨부도면의 한 실시예에 의하여 설명한다. 여기에서 도면은 본 발명손목시계 용두의 구조를 나타내는 확대 종단면도이다.Hereinafter, an embodiment of the accompanying drawings specifically showing the present invention will be described. Here, the drawing is an enlarged longitudinal sectional view showing the structure of the watch watch of the present invention.

본 발명 방수용두의 구조는, 용두 1과 그 내면에 취부된 방수패킹 11, 12와 권진파이프 2 및 상술한 권진파이프 2내에 삽입되어 있는 권진 3과, 코일스프링 4로서 구성되어 있다. 또5, 6, 7, 8, 9는 각각 동채, 유리, 문자판, 무브멘트(movement), 뒷뚜껑을 나타낸다.The structure of the waterproof crown of the present invention is composed of the crown 1, the waterproof packings 11 and 12 mounted on the inner surface thereof, the winding 3 inserted into the winding pipe 2 and the winding pipe 2 described above, and the coil spring 4. 5, 6, 7, 8, and 9 represent copper cladding, glass, dial, movement, and rear lid, respectively.

다음에 본 발명의 주요부분을 상세히 설명하면, 손목시계 용두 1은 원통상으로 형성되고, 이 용두 1의 내주 중앙에는 권진 3에 나삽되는 나사공 1a을 선단부에 가진 돌출부 1b가 형성되어 있다. 또 그 내주 개구부에는 2단의 방수패킹 취부단부 11a, 12a가 설치되어 있다. 상술한 단부 11a, 12a의 개구연부에는 대략 용두 1의 내경과 일치하는 내경의 용두 링 13, 14가 일체로 설치되어 있고, 단부 11a와 용두 링 13 및 단부 12a와 용두 링 14로서 용두 1의 내주면에 얕은 환상요홈 15와, 깊은 환상요홈 16이 형성되어 있다.Next, the main part of the present invention will be described in detail, and the watch crown 1 is formed in a cylindrical shape, and a protrusion 1b having a screw hole 1a which is screwed into the winding 3 at the distal end thereof is formed at the center of the inner circumference of the crown 1. Moreover, two stages of waterproof packing attaching ends 11a and 12a are provided in the inner peripheral opening. The opening edges of the ends 11a and 12a described above are integrally provided with crown rings 13 and 14 of the inner diameter approximately equal to the inner diameter of the crown 1, and the inner peripheral surface of the crown 1 as the end 11a, the crown ring 13, and the end 12a and the crown ring 14. Shallow groove 15 and deep groove 16 is formed.

상술한 방수패킹 11은 단면 D형으로 형성되고, 상술한 용두 1의 얕은 요홈 15에 감합 가능하게 형성되어 있고, 상술한 방수패킹 12는 상술한 용두 1의 깊은 요홈 16에 감합되어있으며, 그 단면은 ㄷ자형으로 형성되어 있다. 상술한 방수패킹 12의 ㄷ자형의 홈안에는 이 패킹의 형상을 유지하기 위한 패킹 링 18이 삽입되어 있다. 상술한 방수패킹 11, 12의 사이에는 일련으로 용두의 회전시 원활히 회전되도록 또 방수패킹 11, 12와 권진파이프 2와의 사이의 밀착성을 좋게하기 위하여 구리스같은 윤활제가 충진되어 있다.The above-mentioned waterproof packing 11 is formed in cross-section D shape, and is formed to be fitted into the shallow groove 15 of the crown 1 described above, and the above-mentioned waterproof packing 12 is fitted into the deep groove 16 of the crown 1 described above. Is shaped like a c. The packing ring 18 is inserted into the above mentioned U-shaped groove of the waterproof packing 12 to maintain the shape of this packing. A grease such as grease is filled between the waterproof packings 11 and 12 so as to smoothly rotate when the crown is rotated in series and to improve adhesion between the waterproof packings 11 and 12 and the winding pipe 2.

상술한 권진파이프 2는 단부를 갖는 원통으로 형성되고, 대경부 2a쪽은 상술한 용두 1의 내주에 삽입되고, 또 소경부 2b쪽은 상술한 동체 5의 외주에서 내주로 관통된 권진파이프 삽입공 5a에 압입되어 있다. 이 권진파이프 2내에는, 권진 3이 삽통되고, 이 권진 3은 용두 1의 나사공 1a에, 그 선단이 나착 고정되어 권진파이프 2내에 회전자재롭게 설치되어 있다. 또 권진파이프 2와 용두 1내주에는 용두 1을 동체 5의 외주방향으로 압압하는 코일스프링 4가 장착되어 있어 용두의 인출조작이 용이하게 된다.The above-mentioned winding pipe 2 is formed into a cylinder having an end portion, the large diameter portion 2a is inserted into the inner circumference of the crown 1 above, and the small diameter portion 2b is penetrated into the inner circumference from the outer circumference of the fuselage 5 described above. It is pressed in 5a. In this winding pipe 2, a winding 3 is inserted, and this winding 3 is rotatably installed in the winding pipe 2, with its tip fixedly screwed into the screw hole 1a of the crown 1. In addition, the coil spring 4 and the inner circumference of the crown 1 are equipped with a coil spring 4 that presses the crown 1 in the outer circumferential direction of the fuselage 5, thereby making it easier to take out the crown.

이상과 같은 본 발명 구성에 의하면 용두 1의 내주와 권진파이프 2외주사이에 2개의 방수패킹 11, 12을 설치하고 그 사이에 윤활유를 충진한 것이어서, 용두 1를 접동시킬 때에, 권진파이프 2와 패킹 11, 12와의 사이에 얇은 기름막이 형성되기 때문에 패킹의 마찰력이 경감되어 권진의 인출조작이 원활하게 된다. 또 권진파이프 2의 외주에 부착한 경우 물을 배제하는 기름의 작용에 의해 물이 물방울상으로 되므로 용두1의 접동시에도, 패킹의 물을 막는 작용이 양호하여 부착수(付着水)에 의한 물의 용두내로의 침투도 전무하다. 또 패킹과 권진파이프간의 밀착은 윤활제를 개재하여 이루어지기 때문에 수중에서도 용두의 인출조작 및 회전조작도 가능하다. 또한, 용두 개구부의 방수패킹을 단면 ㄷ자형으로하고, 이 ㄷ자홈내에 패킹의 형상을 유지하기 위한 경질의 링을 설치했기 때문에 장기사용에 의하여 패킹의 형이 붕괴되는 것을 막고, 또 ㄷ자형으로 형성함에 의하여 이 패킹과 권진파이프와의 접촉면적이 크게되어 고수압에서도, 물이 침입하기 어렵고, 또 고수압에서 ㄷ자형 패킹의 ㄷ형내로 물이 유입하면, 수압이 이 패킹을 벌리려고하는 방향으로 작용하므로 권진파이프와 패킹과의 밀착성이 커져 용두의 방수작용을 촉진시키게하는 등의 여러가지 효과를 가진다.According to the configuration of the present invention as described above, two waterproof packings 11 and 12 are installed between the inner circumference of the crown 1 and the outer circumference of the winding pipe 2 and filled with lubricating oil therebetween. Since a thin oil film is formed between 11 and 12, the frictional force of the packing is reduced and the take-out operation of the winding is smooth. In addition, when it is attached to the outer circumference of Kwonjin Pipe 2, the water is formed in the form of water droplets by the action of oil excluding water. There is no penetration into the crown. In addition, the close contact between the packing and the winding pipe is made through a lubricant, so that the extraction and rotation operation of the crown can be performed in water. In addition, the waterproof seal of the crown opening has a cross-shaped c-shape, and a hard ring for retaining the shape of the packing is provided in the c-groove to prevent the packing from collapsed by long-term use. As a result, the contact area between the packing and the winding pipe becomes large, so that water is difficult to invade even at high water pressure, and when water flows into the c shape of the c-shaped packing at a high water pressure, the water pressure acts in a direction to open the packing. Therefore, the adhesion between the winding pipe and the packing is increased, thereby promoting various effects such as promoting the waterproofing action of the crown.
