Embodiment Construction

[0024] An embodiment of the present invention is illustrated in the accompanying drawings. In FIGS. 1 to 3, reference numeral 1 refers to a shaft made of synthetic resin such as POM (polyoxymethylene), and the shaft 1 includes a flange portion 2 provided at one end thereof. , a deformed shaft portion 3 with a substantially elliptical cross-section provided next to the flange portion 2, and a coupling groove 4 for mounting a positioning ring and a groove for mounting an E ring respectively engraved on the outer periphery of the end portion of the deformed shaft portion 3. Zhougou 5. Reference numeral 6 denotes a fixing member also made of synthetic resin such as POM. The fixed part 6 has a stepped hole 7 composed of a circular hole 7a for positioning ring installation and an oval deformation hole 7b in the axial direction of its central part, and a plurality of positioning grooves 6a constituting the anti-rotation device are arranged on its outer periphery. , 6a..., the deform...

Abstract

In order to fabricate a hinge device which is opened and closed one-sidedly or relatively in respect of a main body of the device, is constituted by a shaft installed with a flange portion at one end portion thereof, a fixing member having a rotational lock which is engaged with other end portion of the shaft such that the shaft does not come off the other end portion, a fixed cam having a rotational lock while rotatably inserting the rotating shaft through a central portion thereof on a side of the flange portion of the rotating shaft, a rotary sliding cam which is installed between the fixed cam and the fixing member, engaged with the shaft, is rotatable along with the shaft and slidable in the axial direction and a compression spring elastically installed between the rotary sliding cam and the fixing member by being wound around the shaft in which the fixed cam is installed with a pair of cam portions at opposed positions at one side face thereof and the rotary sliding cam is installed with projected portions which are brought into press contact with the cam portions of the fixed cam.

Description

technical field [0001] The invention relates to a hinge device, which is suitable for opening and closing various opening and closing parts of small electronic equipment such as portable phones, portable computers and electronic notebooks relative to the main body of the device. Background technique [0002] Such a hinge device is conventionally called a tilt hinge, and can hold an opening and closing member at an arbitrary or predetermined opening angle with respect to the device main body, and various structures combining various cams and springs are known. But no matter which one of them, the structure is too complicated and the production cost is too high. In recent years, the voice of the industry to reduce costs has been increasing. Even in the technical field of such electronic equipment, there are particularly strict requirements for miniaturization and low cost. Contents of the invention [0003] The object of the present invention is to provide such a hinge dev...
