Problems solved by technology

[0004] Although the above-mentioned conventional hinge device has sufficient functions such as opening and closing, stopping, and holding of the display device (cover body), the conventional hinge device has the problems of a large number of parts and a complicated structure.
Therefore, manufacturing is cumbersome, and the manufacturing cost and cost are high, and since the cam parts that fit each other are provided on the cam member and the sliding cam member (the above two cams), there is a limit to shortening (miniaturization) the size (length) in the axial direction.

Embodiment Construction

[0084] In order to illustrate the present invention in more detail, it is illustrated below with reference to the accompanying drawings.

[0085] figure 1 It is a figure which shows the hinge apparatus of 1st Embodiment of this invention, (a) is a front view, (b) is a left side view, (c) is a right side view, figure 2 for figure 1 (c) A-A line enlarged cross-sectional view.

[0086] The hinge device is composed of the following parts: a housing 5 as a base part fixed on one part, such as a body; a movable shaft 1 fixed to another part, such as a cover, freely rotatably installed in the housing 5 ; a spring washer 2 that is a leaf spring member inserted on the movable shaft 1 so as to be rotatably constrained (non-rotatable) but freely movable in the axial direction; , and the rotation is constrained by the housing 5, abutting against the fixed plate 3 of the spring washer 2 mentioned above. The movement of the spring washer 2 and the fixing plate 3 in the axial direction ...

Abstract

Disclosed is a hinge device for openably and closably connecting one member and the other member, including: a base member fixed to the one member; a movable shaft that is rotatably supported by the base member and to which the other member is fixed; a leaf spring member having a curved portion and non-rotatably but axially movably inserted onto the movable shaft; and a fixing plate inserted onto the movable shaft such that the fixing plate does not rotate when the movable shaft rotates but is axially movable, the fixing plate having at least two protrusions provided on its surface in contact with the leaf spring member. The leaf spring member and the fixing plate are pressed into contact with each other for relative rotation therebetween.

Description

technical field [0001] The present invention relates to a hinge device that can openably and closably connect two parts such as a main body and a cover body of small OA equipment such as a notebook personal computer and a mobile phone, a portable terminal equipment, and a toilet seat. Background technique [0002] Notebook PCs, mobile phones and other information equipment are provided with a keyboard on the body, and a display device on the cover, and the cover provided with the display device is connected with a hinge device so that it can be opened and closed, stopped and kept at a position that is convenient for viewing. Angle. [0003] In the past, such hinge devices, as disclosed in Japanese Patent Application Laid-Open No. 10-252739 and Japanese Patent Laid-Open No. 11-44142, etc., are generally provided with a pair of cams whose axes are consistent with each other, can rotate relative to each other, and can approach or leave each other. The cam surfaces of the cams ...
