Ball hinge structure
First Claim
1. A ball hinge structure, comprising:
- a ball hinge rotatably installed inside a hinge housing; and
a first hinge resistor and a second hinge resistor elastically supported with respect to each other by a second spring,wherein the second hinge resistor is in contact with a circumference of the ball hinge,the first hinge resistor is elastically supported by a first spring provided on a top surface of a hinge housing cap coupled to a lower portion of the hinge housing,the ball hinge includes a groove, and when the ball hinge is maintained in a normal position thereof, the first hinge resistor is faced with the groove having a smaller circumference than a circumference having a radius of the ball hinge to apply a weak compression force to the first spring elastically supporting the first hinge resistor, and when the ball hinge is tilted, the circumference of the ball hinge having the radius pushes the first hinge resistor according to a tilted angle thereof, thereby applying a strong compression force to the first spring, and a compression force opposite to the compression force of the first hinge resistor is applied to the second hinge resistor, so a fixing force of the ball hinge changes according to the position of the ball hinge.

Abstract
Provided is a ball hinge structure in which a ball hinge can be freely rotated in various directions and maintain a fixed state. The ball hinge structure includes a ball hinge rotatably installed in a hinge housing; and a first hinge resistor and a second hinge resistor elastically supported with respect to each other by a second spring, wherein the second hinge resistor is closely attached to a circumference at a side of a sphere of the ball hinge, the first hinge resistor is elastically supported by a first spring provided on a top surface of a hinge housing cap coupled to a lower portion of the hinge housing, and a groove is formed in the bottom of the ball hinge, and thus the first hinge resistor is lifted in a position as high as the height of the groove.
