Abstract

The present invention relates to a slider link assembly. More specifically, the present invention relates to a slider link assembly used in a slider for a sliding type of mobile phone. This slider link assembly decreases the number of parts and so reduces production costs and allows the thickness to be slimmed. It also improves the sliding arrangement and allows relatively stable sliding. The slider link assembly having a tension spring according to the present invention comprises: a first link slider; a second link slider constrained in such a way that it can slide in the length direction of the first link slider; and a plurality of tension springs of which the two ends are respectively secured to the other ends of the first and second link sliders. A characterising feature of this slider link assembly lies in the fact that the first and second link sliders have the shape of sheets of metal, and comprise first and second guide slots formed in the length direction on one edge of the respective link sliders, and first and second bent parts obtained by partially cutting away the first and second link sliders corresponding to the first and second guide slots and by bending in such a way as to be able to guide the longitudinal movement and prevent the separation of each of the link sliders.

Description

인장 스프링을 구비한 슬라이더 링크 조립체Slider link assembly with tension spring
본 발명은 슬라이더 링크 조립체에 관한 것이다. 보다 상세하게는 슬라이딩 타입 휴대폰용 슬라이더에 사용되는 슬라이더 링크 조립체에 관한 것으로, 부품 수를 줄여서 제조원가를 절감하고 두께를 슬림화하며, 슬라이딩 구조를 개선하여 보다 안정적으로 슬라이딩 가능한 슬라이더 링크 조립체에 관한 것이다.The present invention relates to a slider link assembly. More particularly, the present invention relates to a slider link assembly used in a slider for a sliding type mobile phone, and more particularly, to a slider link assembly which can more stably slide by reducing the number of parts to reduce manufacturing cost, reduce thickness, and improve sliding structure.
휴대폰용 반자동 슬라이더 조립체에는 슬라이딩 플레이트와 고정플레이트 사이에 탄성부재가 설치되어 있다. 탄성부재는, 양단이 슬라이딩 플레이트와 고정플레이트에 각각 회동 가능하게 고정되어, 슬라이딩 플레이트가 슬라이딩함에 따라서 수축하면서 회전하여, 복원력에 의하여 슬라이딩 방향으로 슬라이딩 플레이트를 자동적으로 이동하도록 하는 기능을 한다.Semi-automatic slider assembly for a mobile phone is provided with an elastic member between the sliding plate and the fixed plate. Both sides of the elastic member are rotatably fixed to the sliding plate and the fixed plate, respectively, and rotate while contracting as the sliding plate slides, thereby automatically moving the sliding plate in the sliding direction by the restoring force.
도 6에는 종래 휴대폰용 반자동 슬라이더 조립체에 사용되는 탄성부재로 한 쌍의 링크 슬라이더와 복수의 인장 스프링을 구비한 슬라이더 링크 조립체가 도시되어 있다. 도 6은 본 발명의 출원인이 발명하여 등록받은 대한민국 등록실용신안 제20-0376773호에 개시된 것이다. 슬라이더 링크 조립체의 다른 이름으로는 업/다운 유지수단으로 표시하기도 한다.6 illustrates a slider link assembly having a pair of link sliders and a plurality of tension springs as an elastic member used in a semi-automatic slider assembly for a conventional mobile phone. Figure 6 is disclosed in the Republic of Korea Utility Model Registration No. 20-0376773 registered and registered by the applicant of the present invention. The slider link assembly may be referred to by other means as up / down retaining means.
도 6에 도시된 종래의 슬라이더 링크 조립체(업/다운 유지수단)는, 금속 재질을 프레스 가공하여 제조한 한 쌍의 링크 슬라이더(31)와, 복수의 인장 스프링(32)과, 한 쌍의 링크 슬라이더(31)가 분리되지 않도록 구속하고 슬라이딩을 안내하기 위한 한 쌍의 핀(313)을 구비한다. 인장 스프링(32)은 링크 슬라이더(31)에 형성된 걸림부(314)에 양단에 형성된 고리가 걸리게 되어 있다. 각각의 링크 슬라이더(31)에는 슬라이딩을 안내하기 위한 길이방향의 안내슬롯(312)이 형성되어 있다.The conventional slider link assembly (up / down holding means) shown in FIG. 6 includes a pair of link sliders 31, a plurality of tension springs 32, and a pair of links manufactured by pressing a metal material. The slider 31 is provided with a pair of pins 313 for restraining it from being separated and for guiding sliding. The tension spring 32 is hooked at both ends by the engaging portion 314 formed on the link slider 31. Each link slider 31 is formed with a longitudinal guide slot 312 for guiding sliding.
상기와 같은 구조를 갖는 종래의 슬라이더 링크 조립체(30), 조립시에 복수의 스프링(32)을 계지하고, 한 쌍의 링크 슬라이더(31)가 분리되지 않도록 구속하기 위한 별도 핀(313)을 사용하기 때문에 조립이 번잡하고, 제조비용이 높다. 또한, 핀(313)이 링크 슬라이더(31)의 외측면으로 돌출하도록 되어 있어서 조립체 전체의 두께가 두꺼워 진다. 또한, 도 6의 점섬원 안에 도시된 그림과 같이, 핀(313)의 외주면이 안내슬롯(312)의 내주면과 두 점에서 점 접촉을 하면서 슬라이딩을 안내하도록 되어 있어서 슬라이딩이 감각이 매끄럽지 못하다. 또한, 핀(313)이 한 쌍의 링크 슬라이더(31)의 길이 방향을 따라 형성된 안내슬롯(312)을 따라서 점 접촉된 상태에서 맞물려 이동하기 때문에 슬라이딩 시 소음이 심하게 발생한다. 이는, 안내슬롯(312)을 내주면이 프레스 가공되어 거친 파단면이 형성되기 때문이다.Conventional slider link assembly 30 having the structure as described above, a separate pin 313 for locking the plurality of springs 32 at the time of assembly and restraining the pair of link slider 31 is not separated. Therefore, assembly is complicated and manufacturing cost is high. In addition, the pin 313 protrudes to the outer side of the link slider 31, so that the entire thickness of the assembly is increased. In addition, as illustrated in the point island circle of Figure 6, the outer peripheral surface of the pin 313 is to guide the sliding while making point contact at two points with the inner peripheral surface of the guide slot 312, the sliding is not smooth. In addition, since the pin 313 is engaged in the point contact state along the guide slot 312 formed along the longitudinal direction of the pair of link slider 31, noise is severely generated when sliding. This is because the inner peripheral surface of the guide slot 312 is pressed to form a rough fracture surface.
본 발명은 상기와 같은 종래의 슬라이더 링크 조립체의 문제점을 해결하기 위한 것이다. 본 발명의 목적은 부품 수를 줄여서, 조립 생산성을 향상하고, 제조원가를 절감하며, 두께를 얇게 할 수 있는 슬라이더 링크 조립체를 제공하는 것이다. 또한, 본 발명의 목적은 슬라이딩시 소음의 발생을 최소화하고 매끄러운 슬라이딩 감각을 제공할 수 있는 슬라이더 링크 조립체를 제공하는 것이다.The present invention is to solve the problems of the conventional slider link assembly as described above.

It is preferable that they can be formed alternately one by one, of course. In addition, since the inner circumferential surfaces of the first and second bent portions 213 and 223 are bent obliquely, both inner circumferential surfaces of the first and second guide slots 214 and 224 which are in contact with the first and second bent portions 213 and 223 are along the length direction of the first and second inclined surfaces 214c, It is preferable to form 224c).
도 4 및 도 5에 참조하면, 제1 및 제2 절곡부(213,223)의 일정한 각도로 절곡되어 기울어진 내측면과, 이에 대향되며 접하고 있는 제1 및 제2 안내슬롯(214,224)의 각각의 경사면(214c,224c)이 면 접촉을 하면서 슬라이딩하기 때문에 부드럽게 작동되고 소음이 적다. 또한, 절곡부는 링크슬라이더의 일부를 절개하여 형성하기 때문에 가공이 용이함은 물론, 이에 따른 제작비용의 절감이 가능하다.4 and 5, the inclined surfaces of the first and second bent portions 213 and 223 are bent at a predetermined angle, and the respective inclined surfaces of the first and second guide slots 214 and 224 opposed to and in contact therewith. Since 214c and 224c slide in surface contact, they operate smoothly and have low noise. In addition, since the bent portion is formed by cutting a portion of the link slider, it is easy to process, and accordingly, the manufacturing cost can be reduced.
복수의 인장 스프링(230)의 양단은 중심부의 외경보다 감소되는 걸림부(231)가 형성되어 있다. 따라서, 인장 스프링(230)의 일단의 걸림부(231)는 제2 링크슬라이더(220)의 제2고정홈(227a)에 삽입되어 제2걸림턱(227b)에 의해 분리되지 않도록 고정되고, 타단에 형성된 걸림부(231)는 제1 링크슬라이더(210)의 제1고정홈(217a)에 각각 삽입되어 제2걸림턱(217b)에 의해 분리되지 않도록 고정되어 있다. 이와 같이 인장 스프링(230)의 양단의 걸림부(231)를 이에 대응되는 제1 및 제2 스프링 고정부(212,222)의 제1 및 제2고정홈(217a,227b)에 용이하게 고정시 킬 수 있으며, 제1 및 제2고정홈(217a,227b)에 형성된 제1 및 제2걸림턱(217b,227b)이 인장 스프링(230)의 양단의 걸림부(231)를 고정시켜 주기 때문에 인장 스프링(230)이 분리되는 것을 방지할 수 있다.Both ends of the plurality of tension springs 230 are formed with a locking portion 231 is reduced than the outer diameter of the central portion. Therefore, the locking portion 231 at one end of the tension spring 230 is inserted into the second fixing groove 227a of the second link slider 220 to be fixed so as not to be separated by the second locking jaw 227b, and the other end thereof. The engaging portions 231 formed in the first insertion grooves 217a of the first link slider 210 are respectively fixed so as not to be separated by the second locking jaw 217b. As such, the locking portions 231 at both ends of the tension spring 230 can be easily fixed to the first and second fixing grooves 217a and 227b of the first and second spring fixing portions 212 and 222 corresponding thereto. Since the first and second locking jaws 217b and 227b formed in the first and second fixing grooves 217a and 227b fix the locking portions 231 at both ends of the tension spring 230, the tension spring ( 230 can be prevented from being separated.
