Description

휴대폰 폴더{CELLULAR PHONE FOLDER}Phone folder {CELLULAR PHONE FOLDER}

본 발명은 휴대폰 폴더에 관한 것으로, 좀더 상세하게는 폴더를 회전가능하게 하여 표시창을 내,외부에서 선택적으로 나타낼 수 있는 휴대폰 폴더에 관한 것이다.The present invention relates to a mobile phone folder, and more particularly, to a mobile phone folder which can selectively display a display window inside and outside by rotating the folder.

일반적으로, 휴대폰의 종류는 크게 폴더형과 플립형으로 크게 나뉘어 지는데, 플립형은 버튼등의 조작부를 단순히 감싸는 플립 및 표시창이 일체로 형성된 구조이고, 폴더형은 기기 본체에 폴더가 힌지를 중심으로 개폐되는 구조이다. 이중, 휴대폰의 소형화 추세에 따라 폴더형이 점차 대중적인 단말기로 보급되는 실정이다.In general, the type of mobile phone is largely divided into a fold type and a flip type, the flip type is a structure in which the flip and the display window that simply wraps the operation unit, such as a button is integrally formed, the fold type is opened and closed around the hinge on the main body of the device Structure. Among these, as the size of mobile phones has become smaller, the folder type is increasingly being used as a popular terminal.

그러나, 폴더형은 폴더로 표시창을 분산함으로써 단말기의 크기를 크게 소형화시킬 수는 있으나 사용하지 않을 때는 항상 기기 본체에 폴더의 표시창이 닫혀 있는 상태를 유지하게 되므로 사용자가 기기의 작동상태를 확인하기 위해서는 폴더를 손으로 개방해야 하는 단점이 있다.However, the folder type can greatly reduce the size of the terminal by distributing the display windows into folders, but when not in use, the display window of the folder is kept closed on the main body of the device so that the user can check the operation state of the device. The disadvantage is that the folder must be opened by hand.

이러한 단점을 해결하기 위해 앞서 실시된 기술로는 폴더의 내,외부에 각각 하나씩의 표시창을 형성한 것이 있으나 이 또한, 별도의 표시창을 형성하기 위해기기의 구조가 복잡해지고 폴더의 두께 증가에 의한 기기 볼륨의 확장과 동시에 원가상승은 피할 수 없는 구조이다.In order to solve the above disadvantages, the above-described technique is to form one display window inside and one outside of the folder. However, in order to form a separate display window, the structure of the device is complicated and the device is increased by increasing the thickness of the folder. As the volume expands, cost increases are inevitable.

본 발명은 상기와 같은 문제점을 해결하기 위해 안출한 것으로, 본 발명의 목적은 폴더의 개폐상태와 상관없이 기기의 작동상태를 하나의 표시창으로 확인할 수 있도록 한 휴대폰 폴더를 제공하는 것에 있다.The present invention has been made to solve the above problems, and an object of the present invention is to provide a mobile phone folder to check the operation state of the device in one display window irrespective of the open or closed state of the folder.

상기의 목적을 달성하기 위하여 본 발명은 본체 케이스와, 폴더 케이스로 이루어져 외관을 형성하는 휴대폰에 있어서, 상기 본체 케이스에 회전 가능하게 지지된 힌지홀더와: 상기 힌지홀더에 형성된 힌지축과: 상기 힌지축이 결합되는 폴더 케이스의 힌지공과: 상기 힌지축과 힌지공 사이에 결합되어 폴더 케이스의 회전시 급격한 회전을 방지하는 클릭스프링과: 상기 힌지공의 폴더 케이스 주위에 원호로 형성되어 안내 및 회전각을 설정하는 안내홈과; 폴더 케이스에 설치되는 표시창으로 구성됨을 특징으로 한다.In order to achieve the above object, the present invention is a mobile phone consisting of a main body case, a folder case to form an appearance, the hinge holder rotatably supported on the main body case: a hinge axis formed on the hinge holder: the hinge Hinge hole of the folder case coupled to the shaft: Click springs coupled between the hinge axis and the hinge hole to prevent sudden rotation during rotation of the folder case: formed by an arc around the folder case of the hinge hole guide and rotation angle Guide groove to set up; Characterized in that the display window is installed in the folder case.

이하, 본 발명의 실시예를 첨부한 도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

본 발명은 크게 본체 케이스(10), 본체 케이스(10)에 결합되어 개폐 및 회전되는 폴더 케이스(20), 상기 본체 케이스(10)에서 폴더 케이스(20)를 연결함과 동시에 개폐동작과 더블어 회전가능하게 하는 힌지홀더(30), 폴더의 개폐에 상관없이 기기의 작동을 사용자에게 시각적으로 디스플레이 하는 하나의 표시창(60)으로 구성된다.The present invention is largely coupled to the main body case 10, the main body case 10, the folder case 20 to be opened and closed and rotated, and the opening and closing operation and double rotation while connecting the folder case 20 in the main body case 10 Hinge holder 30 that enables, and one display window 60 for visually displaying the operation of the device to the user regardless of opening and closing of the folder.

도 1은 본 발명의 구성요소를 나타낸 분리 사시도로서, 이들의 결합관계를 설명하면 다음과 같다.1 is an exploded perspective view showing the components of the present invention, when explaining the coupling relationship as follows.

본체 케이스(10)의 상부에 폴더 케이스가 개폐가능하게 결합될 수 있는 힌지 하우징(11)에 힌지홀더(30)가 회전가능하게 결합된다.The hinge holder 30 is rotatably coupled to the hinge housing 11 to which the folder case can be coupled to open and close to the upper portion of the main body case 10.

힌지홀더(30)는 길이방향의 중앙에 관형태의 힌지축(31)이 일체로 돌출되며 그 단부에 플랜지(32)가 형성되어 있다.The hinge holder 30 has a tubular hinge shaft 31 integrally protruded in the center of the longitudinal direction and a flange 32 is formed at an end thereof.

또한, 힌지축(31)은 원주방향 소정위치에 절결홈(33)이 형성되어 힌지축이 어느정도 탄력적으로 이완 또는 확대될 수 있는 구조를 갖는다.In addition, the hinge shaft 31 has a structure in which a notch groove 33 is formed at a predetermined circumferential direction so that the hinge shaft can be elastically relaxed or enlarged to some extent.

한편, 폴더 케이스(20)에는 힌지홀더(30)의 힌지축(31)이 결합될 수 있는 힌지공(21)이 상단 중앙에 형성되는데, 그 외측 주변부로 일정깊이와 폭을 갖는 반원의 안내홈(22)이 파여져 있다.On the other hand, in the folder case 20, a hinge hole 21 to which the hinge shaft 31 of the hinge holder 30 can be coupled is formed at the center of the upper end, and a semicircular guide groove having a predetermined depth and width toward the outer peripheral portion thereof. (22) is carved.

상기와 같은 힌지축(31)의 외주면에는 클릭스프링(40)이 탄력적으로 끼워져 폴더 케이스(20)의 회전시 급격한 회전을 방지하고 이의 구조는 클릭 스프링(40) 외주면에 형성된 돌기(41)가 힌지공(21) 내주면의 걸림홈(21a)에 완만한 구속력을 갖고 걸림유지된 것이다.Click spring 40 is elastically fitted to the outer circumferential surface of the hinge shaft 31 as described above to prevent sudden rotation when the folder case 20 rotates, the structure of the hinge spring 31 is hinged projections 41 formed on the outer circumferential surface The ball (21) is retained with a gentle restraint force in the locking groove (21a) of the inner circumferential surface.

이와 같이 힌지홀더(30) 자체에서 회전가능하게 결합된 폴더 케이스(20)의 내부에는 표시창(50)이 결합되며 회전감지 스위치(60)가 전기적으로 연결되어 있다.As such, the display window 50 is coupled to the inside of the folder case 20 rotatably coupled to the hinge holder 30 itself, and the rotation detection switch 60 is electrically connected thereto.

도 2는 상기 회전 감지 스위치(60)의 작동상태를 나타낸 것으로, 힌지축(31)의 외주면에 형성된 검출홈(31a)에 회전 감지 스위치(60) 단부의 걸림유무에 따라 회전상태를 감지하게 된다,2 shows an operation state of the rotation detection switch 60, and detects the rotation state depending on whether the end of the rotation detection switch 60 is caught in the detection groove 31a formed on the outer circumferential surface of the hinge shaft 31. ,

이상과 같이 구성된 본 발명의 작동을 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above are as follows.

도 3에서와 같이 폴더가 닫힌 상태에서 폴더 케이스(20)를 열게 되면 (도 1참조) 힌지하우징(11)의 내부에서 힌지홀더(30)가 회전되고, 이 상태에서 폴더를 도 4에서와 같이 힌지홀더(30)에서 돌리면 힌지축(31)에서 힌지공(21)이 회전된다.When the folder case 20 is opened while the folder is closed as shown in FIG. 3 (see FIG. 1), the hinge holder 30 is rotated inside the hinge housing 11, and in this state, the folder is rotated as shown in FIG. 4. When the hinge holder 30 is turned, the hinge hole 21 is rotated on the hinge shaft 31.

이 때, 힌지축(31)과 힌지공(21) 사이에 결합된 클릭스프링(40)은 회전시 돌기(41)가 힌지공(21)의 걸림홈(21a)에 탄력적으로 걸리게 되어 급작스런 회전을 방지하게 되고 소정의 각도로 순차적으로 회전된다.At this time, the click spring 40 coupled between the hinge shaft 31 and the hinge hole 21, the projection 41 is elastically caught in the locking groove (21a) of the hinge hole 21 during rotation to suddenly rotate And rotated sequentially at an angle.

도 5는 상기의 폴더 회전 후 상태이고 도 6은 회전 후 폴더를 닫은 상태이다.FIG. 5 is a state after the folder rotation and FIG. 6 is a state in which the folder is closed after the rotation.

이 때, 표시창(50)은 폴더를 닫은 상태에서 외부로 노출되며 회전에 의해 역상으로 변환된 영상은 휴대폰 내부의 전자회로에 의해 소프트웨어적으로 변환하여 정상의 영상으로 복원한다.At this time, the display window 50 is exposed to the outside while the folder is closed, and the image converted to reverse phase by rotation is converted into software by the electronic circuit inside the mobile phone to restore the normal image.

이상에서 살펴 본 바와 같이 본 발명은 폴더를 힌지부 기점에서 다시 회전시켜 폴더의 내면을 외부로 노출가능하게 한 구조를 가짐으로서, 폴더의 내면에 형성된 표시창을 외부로 나타낼 수 있게 하였다.As described above, the present invention has a structure in which the inner surface of the folder is exposed to the outside by rotating the folder again from the hinge point, so that the display window formed on the inner surface of the folder can be displayed to the outside.

따라서, 사용자가 휴대폰을 평상시와 같이 사용할 때는 폴더를 회전시키지 않은 상태에서 사용하고 표시창을 외부로 나타내 사용하고자 하는 경우에는 폴더를 회전시킨 상태에서 개폐시킴으로서 사용자가 선택적으로 표시창을 확인할 수 있다.Therefore, when the user uses the mobile phone as usual, the user can selectively check the display window by opening and closing the folder in a rotated state when using the folder without rotating the folder and displaying the display window outside.

이것은 기존의 폴더의 내외측으로 두개의 표시창을 형성함으로써 발생되는 기기의 복잡성과 원가상승의 요인을 원천적으로 배제하고 기기의 단순성에 의한 신뢰도의 향상 및 양산시 원가절감의 효과를 가진다.This fundamentally excludes the complexity and cost of equipment caused by forming two display windows inside and outside of an existing folder, and has the effect of improving reliability and cost reduction in mass production.
