본 발명은 슬라이드식 핸드폰의 탄성부재에 관한 것으로 특히 슬라이드부재가 일정위치를 지나면 탄성력이 작용하여 자동으로 개폐되도록 하는 역할을 하는 탄성수단을 플라스틱 단일 구성요소로 대체할 수 있도록 한 것이다.The present invention relates to an elastic member of a slide-type mobile phone, and in particular, to allow the plastic member to replace the elastic means that plays a role of automatically opening and closing the elastic member when the slide member passes through a certain position.

일반적으로 슬라이드식 핸드폰은 슬라이드부재를 일정한 위치까지 밀어주면 자동으로 열리거나 닫히도록 하기 위한 탄성수단을 구비하고 있다.In general, the slide-type mobile phone is provided with an elastic means for automatically opening or closing the slide member to a certain position.

종래의 슬라이드식 핸드폰에 사용되는 탄성수단은 도 1에 도시된 바와 같이 슬라이드부재(1)와 가이드부재(2)사이에 한쌍의 코일스프링(3)을 사용하였으나 이것은 코일스프링(3)의 엉킴현상이 발생되고 이러한 엉킴현상은 광케이블이 긁혀 손상되는 원인이 될 뿐만 아니라 슬라이드부재(1)가 슬라이딩될 때 소음이 비교적 크게 발생되는 등의 문제점을 있었다.The elastic means used in the conventional slide-type mobile phone used a pair of coil springs (3) between the slide member (1) and the guide member (2) as shown in Figure 1 but this is the entanglement of the coil spring (3) This entanglement is not only cause the optical cable is scratched and damaged, but also has a problem such that noise is generated relatively large when the slide member (1) is sliding.

종래에도 이러한 문제점을 개선하기 위하여 도 2에 도시된 바와 같이 4개 정도의 코일스프링(3a)을 원통형의 튜브(3b)에 넣고 코일스프링(3a)의 힘을 전달받을 수 있는 철심(3c)을 하우징(3d)에 조립한 포고핀 형식의 탄성수단이 사용되었으나 이것은 탄성수단를 구성하는 조립부품이 많기 때문에 생산성이 저하될 뿐만 아니라 상기 구성요소만으로는 조립될 수 없기 때문에 아웃서트 사출을 하여 힌지를 만들어 주는 등의 폐단이 있었다.In order to improve such a problem in the related art, as shown in FIG. 2, four coil springs 3a are placed in a cylindrical tube 3b and an iron core 3c capable of receiving the force of the coil springs 3a is provided. The pogo pin type elastic means assembled to the housing 3d was used, but this is not only the productivity is lowered due to the large number of assembly parts constituting the elastic means, but also the components can not be assembled by insert injection to make the hinge. There was a back lung.

본 발명이 이루고자 하는 기술적 과제는 슬라이드부재가 일정위치를 지나면 부드럽게 열리고 닫히도록 하는 역할을 하는 핸드폰용 탄성수단를 하나의 플라스틱 사출물로 대체할 수 있게 함으로써 부품수를 최소화 시켜 조립작업을 용이하고 핸드폰을 경량화하는데 일조할 수 있음은 물론 원가절감 효과가 있는 우수한 새로운 타입의 슬라이드식 핸드폰의 탄성부재를 제공하기 위한 것이다.The technical problem to be achieved by the present invention is to facilitate the assembly work by minimizing the number of parts by allowing the plastic member to replace the elastic means for the mobile phone that serves to smoothly open and close when the slide member passes through a certain position to facilitate the assembly work and light weight mobile phone In addition to being able to help to provide a cost-effective elastic member of the new type of slide-type mobile phone.

본 발명의 기술적 과제는 플라스틱 사출물로써 양쪽에 슬라이더부재와 가이 드부재에 각각 회동가능하게 결합되는 힌지결합부가 형성되고 이 힌지결합부를 연결하는 중심선을 기준으로 상하로 볼록한 형태의 공간부가 형성되며 상기 공간부를 사이에 두고 폭이 중앙의 볼록한 부위에서 힌지결합부 측으로 갈수록 좁아지는 변형부에 완충공간부를 형성하여 슬라이더부재가 이동함으로써 힌지결합부 사이의 거리가 짧아지면 다수의 탄력변위살이 눌려지도록 한 슬라이드식 핸드폰의 탄성부재에 의하여 달성되어진다.The technical problem of the present invention is a plastic injection molding formed on both sides of the hinge member is rotatably coupled to the slider member and the guide member on both sides, and the space portion of the convex shape is formed up and down on the basis of the center line connecting the hinge coupling portion is formed Sliding type which is formed so that the width of the hinge coupling part is pressed when the distance between the hinge parts is shortened by forming the buffer space part in the deformation part that becomes narrower from the convex part of the center to the hinge coupling part with the width between them. It is achieved by the elastic member of the mobile phone.

본 발명의 바람직한 실시예를 첨부 도면에 의거 상세히 설명하면 다음과 같다.Preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 3은 본 발명의 탄성부재를 보인 사시도로써 이것은 도시된 바와 같이 플라스틱 사출물로써 양쪽에 슬라이더부재(20)와 가이드부재(10)에 각각 회동가능하게 결합되는 힌지결합부(31)(32)가 형성되고 이 힌지결합부(31)(32)를 연결하는 중심선(R)을 기준으로 상하로 볼록한 형태의 공간부(33)가 형성되며 상기 공간부(33)를 사이에 두고 폭이 중앙의 볼록한 부위에서 힌지결합부(31)(22) 측으로 갈수록 좁아지는 변형부(34)에 완충공간부(35)를 형성하여 다수의 탄력변위살(36)이 슬라이더부재(20)가 이동함으로써 힌지결합부(31)(32) 사이의 거리가 짧아지면 눌려지도록 한 슬라이드식 핸드폰의 탄성부재에 관한 것이다.3 is a perspective view showing an elastic member of the present invention, which is a hinged portion 31, 32 which is rotatably coupled to the slider member 20 and the guide member 10 on both sides as a plastic injection molding, as shown. And a space portion 33 having a convex shape formed up and down with respect to the center line R connecting the hinge coupling portions 31 and 32 is formed, and the width of the center portion is convex with the space portion 33 interposed therebetween. By forming the buffer space portion 35 in the deformable portion 34 narrowed toward the hinge coupling portion 31, 22 side from the site, a plurality of elastic displacement teeth 36, the slider member 20 to move the hinge coupling portion It relates to an elastic member of a slide-type mobile phone to be pressed when the distance between the (31) and (32) is shortened.

상기 탄성부재는 사출공정을 거쳐 제작될 수 있는 플라스틱 재질로 별도의 힌지수단을 사용하지 않고도 일체로 형성된 힌지결합부(31)(32)를 이용하여 슬라이더부재(20)와 가이드부재(10)에 결합할 수 있을 뿐만 아니라 금속재 스프링으로 인 한 전파간섭현상이 발생된 요인을 근본적으로 해소할 수 있을 것으로 기대된다.The elastic member is a plastic material that can be manufactured through an injection process, and uses the hinge coupling parts 31 and 32 integrally formed on the slider member 20 and the guide member 10 without using a separate hinge means. Not only can it be combined, it is also expected to fundamentally solve the cause of the interference caused by the metal spring.

상기 힌지결합부(31)(32)는 플라스틱 사출물의 특성상 본 발명이 사용되는 핸드폰의 구조에 적합하도록 다양한 변형이 가능하다.The hinge coupling parts 31 and 32 may be variously modified to be suitable for the structure of a mobile phone in which the present invention is used, due to the characteristics of the plastic injection molding.

상기 공간부(33)는 전체적으로 볼 때 상하로 볼록한 볼록렌즈 모양이며 그 양측에는 폭이 좁은 홈부(33a)(33b)가 힌지결합부(31)(32)쪽으로 형성 되어있다.The space portion 33 is a convex lens shape that is convex vertically when viewed as a whole, and narrow groove portions 33a and 33b are formed toward the hinge coupling portions 31 and 32 on both sides thereof.

상기 변형부(34)는 공간부(33)를 사이에 두고 볼록한 중앙부분의 폭이 넓고 힌지결합부(31)(32)쪽으로 갈수록 좁아지며 일정한 두께를 갖는 부분으로 다수의 완충공간부(35)가 다수의 탄력변위살(36)이 구비되도록 형성된 것이다.The deformable portion 34 has a wider portion of the convex central portion with the space portion 33 interposed therebetween, and narrows toward the hinge coupling portions 31 and 32 and has a predetermined thickness. Is formed to be provided with a plurality of elastic displacement teeth (36).

상기 완충공간부(35)는 대략 브메랑과 같은 모양으로 볼록한 중앙부위의 폭이 양쪽으로 갈수록 좁아지도록 형성되어 있다.The buffer space portion 35 is formed so that the width of the convex center portion becomes narrower toward both sides in a shape similar to a vemeran.

도 4a는 플라스틱 사출물인 본 발명의 탄성부재를 가이드부재(10)와 슬라이드부재(20)에 설치하여 슬라이드부재(20)가 상부에 위치한 상태를 보인 도면이다.Figure 4a is a view showing a state in which the slide member 20 is placed on the upper portion by installing the elastic member of the present invention, which is a plastic injection molding to the guide member 10 and the slide member 20.

이것은 본 발명의 탄성부재에 외력이 작용하지 않는 상태로써 슬라이드부재 (20)를 도 4b에 도시된 바와 같이 당기게 되면 힌지결합부(31)(32)의 거리가 짧아지게 되는데 이때 변형부(34)에는 양쪽에서 눌러주는 외력이 작용하게 되고 탄력변위살(36)은 중앙부위가 돌출되는 상태로 변형된다.This is when the slide member 20 is pulled as shown in FIG. 4B with no external force acting on the elastic member of the present invention, and the distance between the hinge coupling parts 31 and 32 becomes short. There is an external force to press on both sides and the elastic displacement meat 36 is deformed to the state protruding the central portion.

탄력변위살(36)이 눌려지는 상태는 힌지결합부(31)(32)의 거리가 가장 짧아지는 지점까지이며 슬라이드부재(20)를 계속해서 밀어내려 이 상태를 지나게 되면 눌려졌던 탄력변위살(36)이 원상태로 돌아가려는 탄성력이 슬라이드부재(20)에 작용하게 됨으로써 핸드폰 사용자가 힘을 가하지 않더라도 슬라이드부재(20)가 도 4c 에 도시된 바와 같이 하부로 이동하게 된다.The state of the elastic displacement meat 36 is pressed up to the point where the distance between the hinge coupling parts 31 and 32 is the shortest, and the elastic displacement meat that was pressed when the slide member 20 continues to be pushed past this state ( The elastic force to return to the original state 36 acts on the slide member 20 so that the slide member 20 moves downward as shown in FIG. 4C even if the mobile phone user does not apply force.

슬라이드부재(20)를 밀어올릴때도 힌지결합부(31)(32)의 거리가 가장 짧아지는 지점까지는 탄력변위살(36)이 눌려지기 때문에 어느정도의 저항을 갖게되나 그 지점을 지나게되면 탄성력에 의해 부드럽게 이동하게 된다.Even when the slide member 20 is pushed up to the point where the distance between the hinge coupling parts 31 and 32 becomes the shortest, the elastic displacement meat 36 is pressed, so that there is some resistance, but when the point passes by the elastic force It will move smoothly.

이와같이 본 발명은 1개의 부품으로 이루어진 플라스틱 사출물만으로 4개의 코일스프링, 이 코일스프링이 넣어지는 4개의 튜브, 철심, 하우징으로 구성된 종래의 탄성수단을 대체하여 핸드폰 사용자가 슬라이드부재(20)를 부드럽게 열고 닫을 수 있도록 한 것이다.As described above, the present invention replaces the conventional elastic means composed of four coil springs, four tubes into which the coil springs are inserted, iron cores and housings by using only one plastic injection molded part, so that the mobile phone user opens the slide member 20 gently. It is to be closed.

이와같이 된 본 발명의 탄성부재는 가이드부재와 슬라이드부재와 결합하기 위하여 별도의 힌지수단을 제작할 필요가 없을 뿐만 아니라 1개의 부품으로 이루어진 플라스틱 사출물로써 4개의 코일스프링, 이 코일스프링이 넣어지는 4개의 튜브, 철심, 하우징으로 구성된 종래의 탄성수단을 대체할 수 있기 때문에 조립이 용이하여 생산성이 증대되며 90％이상의 원가절감 효과 등이 있는 우수한 발명이다.In this way, the elastic member of the present invention does not need to manufacture a separate hinge means in order to be combined with the guide member and the slide member, as well as four coil springs and four tubes into which the coil springs are inserted as a plastic injection molded part. Since it is possible to replace the conventional elastic means consisting of, the core, the housing is easy to assemble, the productivity is increased, and is an excellent invention having a cost reduction effect of 90% or more.

이상에서는 본 발명을 첨부 도면에 한정하여 설명하였으나 여기에 한정되는 것은 아니며, 본 발명의 기술적 사상을 벗어나지 않는 범위 내에서 다양한 변형 실시가 가능함은 물론이다.The present invention has been described above with reference to the accompanying drawings, but is not limited thereto, and various modifications may be made without departing from the technical spirit of the present invention.
