To prevent them from escaping to the top. And the groove 13 is formed on one side of the tubular body 11 of the hinge housing 10 so that the connecting rod 22 of the ball hinge 20 can be inserted into the groove 13 to rotate horizontally.

It is preferable that the protrusion 15 is formed in the arc part 14 of the hinge housing 10 so that the rotation of the sphere 21 of the ball hinge 20 can be easily configured.

The lower end of the hinge housing 10 is fixed to the lower structure to apply such a hinge structure, the connecting rod 22 is connected and fixed to the upper structure. Here, the lower structure means a lower support, and the upper structure may mean an upper support, but is not necessarily limited to the support.

As one embodiment of the upper structure, as shown in Figure 10, the upper fixture 200 is installed on the top of the support 100, the upper fixture 200 is the inner end of the housing 210 made of a hollow tubular The housing cap 250 is detachably fixed thereto, and the resistor 230 is elastically supported by the spring 240 supported by the housing cap 250. The ball hinge 220 is fixed by the resistor 230 to rotate inside the housing 210 while receiving the elastic force. The lag 222 is fixed to the ball hinge 220 is inserted and fixed to the lag stopper 300 fixed to the upper end of the upper tube 130 of the support (100).

As shown in FIGS. 9 and 10, the lag stopper 300 has a groove 312 formed on the hollow tubular body 311, and a thread is formed on the lower outer diameter of the body 311. Incision groove 315 is formed to facilitate the coupling but may not necessarily be formed. And a pair of grooves are formed in the groove portion 312 of the body 311, the locking hook 332 of the fixing cover 330 to be described later is inserted and fixed.

A stopping jaw 313 and a spring support jaw 314 protrude from the groove 312 before and after the hole into which the lag 222 of the upper fixture 200 is inserted, and the actuator 320 is formed in the groove 312. Is installed.

The actuator 320 is formed of a rectangular body 321, is formed with a lag hole 323 penetrating up and down to the center of the body 321, the spring hole 325 which is vertically penetrated before and after the lag hole 323, respectively; The first hole 322 is formed. It is inserted into the spring support jaw 314 and the stopping jaw 313 in the spring hole 325 and the first hole 322, respectively, and installed in the spring support jaw 314 from the spring hole 325 to the spring 340. The actuator 320 is elastically supported. The first hole 322 is inserted into the stopping jaw 313 serves to limit the moving distance of the actuator (320).

The locking end 324 formed at one side of the lower end of the lag hole 323 always pushes the actuator 320 in the direction of the lag 222 by the force of the spring 340, and the groove 222-1 formed in the lag 222. ) Position is fixed. Since one end of the actuator 320 protrudes out of the housing 310, pressing the latch 324 retreats to release the fixed state.

When the fixing cover 330 is fitted in the state in which the actuator 320 is installed, the detachment of the actuator 320 is prevented. At this time, the lag hole 333 is formed in the center of the body 331 of the fixing cover 330, the hook hook 332 is formed on both sides.

When the fixed state of the lag is released by pressing the actuator 320, the lag 222 is pulled out from the upper tube 130 to support the portable device. That is, the portable device 2 is supported on the table or the floor by the lag 222 like a reading table.

When the ball hinge 20 is inserted into the inside of the hinge housing 10, the ring 25 is moved to the middle of the ball hinge 20 so as to relieve friction between the sphere 21 of the ball hinge 20 and the hinge housing 10. A ring 25 made of acetal is installed to be located between the tube 11-1 and the sphere 21.

The second hinge register 30 is in close contact with one side of the sphere 21 of the ball hinge 20 and serves to suppress the rotation or swing of the ball hinge 20 by friction and elastic force.

The first hinge register 50 is elastically supported by the first spring 60 installed on the upper surface of the hinge housing cap 70 coupled to the lower portion of the hinge housing 10. A nut part 16 is formed at the lower end of the inner diameter of the hinge housing 10 to be fastened to the bolt part 73 formed at the outer diameter of the disc body 71 of the hinge housing cap 70. A hole 72 is formed in the center of the disc 71 of the hinge housing cap 70 so that the support portion 52 protruding toward the lower center of the body 51 of the first hinge register 50 is inserted.

The support 52 is movable up and down along the hole 72 according to the change of the elastic force, but the lower end of the first spring 60 is supported on the upper surface of the hinge housing cap 70.

The upper surface 53 of the first hinge register 50 forms an arc with a gentle center, but is formed to be almost flat as shown in the drawing. The edge of the upper surface 53 is formed with the same curvature as the sphere 21 of the ball hinge 20 to be in contact with each other with the sphere 21 in the initial state.

The first hinge register 50 is positioned on the top of the groove portion 23 formed at the bottom of the sphere 21 on the upper surface 53 and the connecting rod 22 is vertical. Since the hinge register 50 is located at the bottom, the compressive force acts differently on the first spring 60.

That is, since the groove portion 23 is formed, the state of the sphere 21 is shaved away from the original circle, so that the diameter around the groove portion 23 becomes smaller as compared with the original sphere 21. Therefore, the first hinge register 50 that elastically contacts the sphere 21 is raised to the top. In this state, the distance between the second hinge register 30 and the first hinge register 50 becomes the narrowest, so that the elasticity of the second spring 40, which is the compression spring, acts the strongest so that the sphere of the ball hinge 20 21).

11, the first spring 60, the dish spring supports the first hinge register 50 with a minimum torque value, and the second hinge register 30 supports the hinge 20 with a strong compressive force. Will be supported.

The groove 23 is formed at the bottom of the ball hinge 20 so that the position of the first hinge register 50 is raised by the height of the groove 23 in the intact sphere when the initial position, that is, the connecting rod 22 is vertical. When the ball hinge 20 elastically supports the first hinge register 50, a weak compressive force is applied to the first spring 60.

When the ball hinge 20 is inclined, the sphere 21 other than the groove part 23 presses the first hinge register 50 according to the degree of rotation, thereby generating a strong compressive force of the first spring 60.

The groove 54 is formed around the first hinge register 50 so that the lower portion of the second spring 40, which is a compression spring, is inserted, and the groove portion is entirely formed at the bottom of the ring-shaped body 31 of the second hinge register 30. 23 is formed so that the upper portion of the second spring 40 is inserted.

The urethane contact portion 33 is formed on the upper portion of the second hinge register 30 to be in close contact with the sphere 21 of the ball hinge 20, and the support portion 52 has a cylindrical shape at the center of the bottom of the first hinge register 50. It is formed to protrude to be supported so as to be movable through the hole 72 formed in the center of the hinge housing cap 70.

12 and 13 illustrate a state in which the ball hinge 20 starts to be inclined. As the ball hinge 20 is inclined, the protrusion, which is an edge of the groove 23, moves the first hinge register 50 downward. Pushed out. At this time, the first hinge register 50 compresses the first spring 60 to generate a strong compressive force at the contact portion of the ball hinge 20 which is in contact with the first hinge register 50.

In addition, at this time, the first hinge register 50 is raised to the highest position and the distance between the second hinge register 30 in contact with the ball hinge 20 is the smallest and the second spring 40, which is strongly compressed, is the first hinge register. As the (50) goes down, the gap becomes wider, and the compressive force decreases relatively.

Therefore, since the load applied to the ball hinge 20 by the second hinge register 30 is weakened, it helps to smoothly move the ball hinge 20. On the other hand, since a strong elastic force acts on the first hinge register 50, the supporting force is increased in the stopped state.

The urethane contact part 33 of the double-injected second hinge register 30 delivers a continuous resistance force to maintain a constant momentary force applied to the hinge 20 by self-resistance force by friction.

14 and 15, when the ball hinge 20 is further inclined, the protruding portion of the edge of the groove 23 passes through the upper surface 53 of the first hinge register 50, and the first hinge register. 50 will decrease the force pushed downward. At this time, the first hinge register 50 moves upward again, and the second spring 40 is compressed again to hold the ball hinge 20.

As described above, the second hinge register 30 is configured such that the compressive force opposite to the compressive force of the first hinge register 50 is applied to change the fixing force of the ball hinge according to the position.
