Embodiment Construction

[0030] Next, several embodiments of the present invention will be described with reference to FIGS. 1-14.

[0031] First, a first embodiment will be described with reference to FIGS. 1 to 8 . In this embodiment, the hinge assembly of the present invention is used for a notebook type personal computer. Figure 7 and Figure 8 As shown, a notebook type personal computer A includes a keyboard B (one of the above two objects (first object)), and a display C (the other of the above two objects (second object)). The left and right opposite ends of the lower side of the display C are rotatably connected with the left and right opposite ends of the front side of the keyboard B through hinge assemblies 1, 1 for rotation around the horizontal rotation axis L. The display C can be rotated approximately 90° in the normal direction and in the reverse direction from the upright position (intermediate position) shown in FIG. 4 . In FIG. 4 , the display C stands vertically relative to the k...

Abstract

Disclosed is a hinge member, wherein a shaft part (3A) of a second hinge member (3) is press-fitted into a support hole (23) of a first hinge member (2). By this, frictional resistance is generated between an inner peripheral surface of the support hole (23) and an outer peripheral surface of the shaft part (3A). A coiled spring (4) is disposed between the first hinge member (2) and the second hinge member (3). The coiled spring (4) biases the first and second hinge members (2, 3) such that when the first and second hinge members (2, 3) are turned in normal and reverse directions from a predetermined neutral position, the first and second hinge members (2, 3) are returned towards the neutral position side.

Description

technical field [0001] The present invention relates to a hinge assembly suitable for rotatably connecting two objects such as a keyboard and a liquid crystal display of a notebook personal computer. Background technique [0002] Generally, a hinge assembly for a notebook personal computer includes a pair of hinge elements fixed to a keyboard and a display, respectively. One hinge element has a bearing hole and the other hinge element has a shaft portion. The shaft portion is rotatably inserted into the supporting hole, so that the pair of hinge members can be rotatably connected together, thereby also rotatably connecting the keyboard and the display together. The shaft portion is a press fit with the bearing hole. Due to this, a frictional resistance is generated between the outer peripheral surface of the shaft portion and the inner peripheral surface of the bearing hole. The resulting frictional resistance can keep the display at any rotation...
