That is, in accordance with the rotation of the operating cam 20, the main piston 30 is moved to the operation cam 20 side, and the piston valve 50 is advanced to the main piston 30 side.

At this time, the installation space (S) between the main piston (30) and the end plug (40) is filled with the injected working oil (15).

Thereafter, when a momentary force, such as pulling or pushing a door fixed at 90 degrees by the user, is applied to the door, the door rotates to rotate the operation cam 20, The piston 30 is moved toward the end plug 40 side.

At this time, the main piston 30 pressurizes the operating oil 15 to the end plug 40 side instantaneously, and the working oil 15 flows into the inlet hole 91 side of the head 90.

The operating oil 15 flowing into the inlet hole 91 is disposed in the operating space 82 of the mounting housing 80 and is moved backward while the opening / closing plunger 100 supported by the pressure spring 110 is moved backward, Thereby opening and closing the inflow hole 91 of the gasket.

When the operating oil 15 flows into the operating space 82 of the mounting housing 80 through the opening hole 91 as described above, the operating oil 15 flows through the connecting passage 83, The door is closed at a 90 ° angle while being discharged through the second flow path 42 of the main body 10 to the first flow path 16 of the main body 10.

On the other hand, the floor hinge 1 may have different breaking forces applied to the door fixed at a 90 degree angle due to abrasion due to use, load of the door, etc., and the processing of parts constituting the breaking force adjusting device 70 Depending on the degree of tolerance, the force of retraction can be changed.

Particularly, since the machining tolerance of the inlet hole 91 formed in the head 90 of the canceling force adjusting device 70 and the elasticity of the pressing spring 110 are greatly different from the set values, it is necessary to adjust the breaking force .

6, the tool 140 is inserted into the tool insertion portion 132 formed on the handle 130 to rotate the handle 130 to one side. At this time, the rotating handle 130 advances the regulator 120 and compresses the pressing spring 110 pressing the opening / closing plunger 100.

Accordingly, the opening / closing plunger 100 is advanced by the pressing force of the pressing spring 110 to be compressed and can be brought into close contact with the inlet hole 91 of the head 90 with stronger force.

In other words, the opening and closing plunger 100 is provided with a canceling force applied to the door fixed at an angle of 90 ° to be released by a higher force, while a repulsive force against the pressure of the operating oil 15 flowing through the inlet hole 91 is more strongly generated. The power can be increased.

On the other hand, when the handle 130 is rotated in a direction opposite to the above-described direction, the regulator 120 is moved backward to weakly lower the compressive force of the pressing spring 110 pressing the opening / closing plunger 100 .

Accordingly, the detent force applied to the door fixed at an angle of 90 degrees can be lowered.

The opening and closing plunger 100 lowers the closing force applied by the lower force to the door fixed at the angle of 90 ° while the repulsive force against the pressure of the operating oil 15 flowing through the inlet hole 91 is low .

As described above, the floor hinge 1 according to the embodiment of the present invention is configured such that, when the door is rotated at an angle of 90 degrees through the release force adjusting device 70 and fixed in the open state, Which is a force exerted on the surface of the substrate, can be adjusted as needed.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, And all changes to the scope that are deemed to be valid.
