Title:
BALL HINGE STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2013/009041
Kind Code:
A3
Abstract:
The present invention relates to a ball hinge which can be freely rotated in various directions and maintain a fixed state. A ball hinge (20) is rotatably installed in a hinge housing (10). A first hinge resistor (50) and a second hinge resistor (30) are elastically supported with respect to each other by a second spring (40). The second hinge resistor (30) is closely attached to a circumference at a side of a globule (21) of the ball hinge (20). The first hinge resistor (50) is elastically supported by a first spring (60) disposed on a top surface of a hinge housing cap (70) coupled to a lower portion of the hinge housing (10). A groove (23) is formed in the bottom of the ball hinge (20). Thus, when the ball hinge is disposed in its regular position, the first hinge resistor (50) is lifted in position by the height of the groove (23) in a globular shape. As a result, the ball hinge (20) applies a weak compression force to the first spring (60) elastically supporting the first hinge resistor (50). If the ball hinge (20) is tilted, the globule (21) outside the groove (23) pushes the first hinge resistor (50) according to a rotated degree of the globule (21) outside the groove (23) to generate a strong compression force through the first spring (60). A compression force opposite to the compression force of the first hinge resistor (50) is applied to the second hinge resistor (30) to change a fixing force of the ball hinge according to the position of the ball hinge.
