As described above, the hinge according to the present invention is coupled as in the front sectional view of FIG. 3 in the same order as shown in the separated perspective view of FIG. 2. Next, with reference to Figures 5 to 7 will be described in detail the operation of the respective components inside the hinge bundle 100 of the present invention according to the opening and closing of the door. For reference, it should be understood that the operation of the hinge according to the present invention to be described below with reference to FIGS. 5 to 7 illustrates the operation of the left hinge HL of FIG. 1.

FIG. 5 is a sectional view of the coupling state of the pressure cam of the hinge HL and the rotating shaft of the hinge HL of FIG. 2 when the door is fully open, and a sectional view of the main part of the hinge HL when the door is closed. Sectional view of the coupling state of the pressure cam and the rotating shaft and the main portion of the hinge (HL) when the coupling state, Figure 7 is a coupling state of the pressure cam and the rotation shaft of Figure 6 when the door is fully closed and the hinge (HL) It is sectional drawing of main part.

First, referring to FIG. 5, the pressurizing cam 140 provides a compressive force corresponding to the rotation of the rotation shaft 120 to the spring 130 while moving in a linear direction with respect to the rotation of the rotation shaft 120. It converts rotational motion into linear motion. A guide 141 is provided on the outside of the pressure cam 140 to move forward and backward only in a linear direction along the guide groove 111 provided inside the housing. On the other hand, the guide 141 of the pressure cam 140 may be formed on the outer circumferential surface of the pressure cam 140 in the form of a guide groove when the guide groove 111 is provided as a guide rail.

In the initial assembly state of the hinge according to the present invention, since the spring 130 is easy to be assembled without being compressed, the door 20 coupled to the fixing part 213 of the door frame 210 is provided in the cabinet 10. The angle formed with the fixing frame of 11 is coupled in a state where the angle further upwards from the horizontal. After the coupling is completed, the door 20 is lowered and is level with the fixing frame 11 until the elastic force of the spring 130 and the self-gravity of the door 20 are balanced, and the first stop state is achieved.

As shown in FIG. 5, at this time, both protruding ends of the guide pins 121 of the rotation shaft 120 are maintained at the valleys 145 of the cam surface 143 of the pressure cam 140, and the door The frame 210 is in a state in which the door 20 is completely opened in a horizontal state. Here, the minimum elastic force of the spring 130 may be set to a value that can withstand the self-gravity of the entire door 20 including the door frame 210.

On the other hand, reference numeral 180 of FIG. 5 shows a mounting member for coupling the fixing plate 113 to the fixing frame 11 of the upper cabinet, reference numeral 185 is a vertical deviation adjusting screw, with reference to FIGS. 10 and 11 in detail. Will be described later.

Subsequently, when the door frame 210 is rotated to close the door 20, the rotation shaft 120 coupled to the door frame 210 rotates simultaneously with the rotation of the door frame 210, and at the same time, the rotation shaft. Guide pin 121 provided at the end of the 120 is to slide along the cam surface 143, the pressure cam 140 is downward as the guide pin 121 presses the cam surface 143 (front sectional view of Figure 3). In the left side, increasing the compressive force to the spring 130 in the minimum compressed state (or decompressed state). Accordingly, the elastic force generated in the spring by the reaction of the increased compressive force is transmitted to the rotating shaft 120 again through the pressure cam 140, thereby balancing the self-gravity of the door 20 fixed to the rotating shaft 120, By maintaining the current rotation angle of the door 20, the door 20 remains open at the current angle unless the user applies more force to the door 20.

When the guide pin 121 is positioned on the floor 147 as shown in Figure 6 past the cam surface 143, the compression force applied to the spring 120 is the maximum, the maximum compressed spring 120 ), The elastic force applied to the door 20 is also maximized. At this time, the door 20 is almost closed.

FIG. 7 illustrates a coupling state of the rotation shaft 120 and the pressure cam 140 in a state where the door 20 is vertical, that is, in a completely closed state, and the guide pin 121 of the rotation shaft 120 is It is located in the inclined portion of the cam surface 143 beyond the floor 147, which is the maximum compression point of the spring 130.

At this time, the guide pin 121 of the rotating shaft 120 is subjected to the force to slide to the bone 145, the lower compression force acts by the elastic force of the spring 130, the door 20 as shown in FIG. Since it is in contact with the front surface of the cabinet, no further rotation (clockwise) is possible, so that the door 20 keeps the open space of the cabinet elastically closed. In this state, in order to open the door 20, a force exceeding the floor 147, which is the maximum compression point of the spring 130, must be applied counterclockwise. That is, in the closing operation of the door 20 leading to FIGS. 6 and 7, since the elastic force of the spring is generated from the maximum compression state of FIG. 6 to the state of FIG. 7, the spring 130 generates the largest elastic force just before closing. The rotary shaft 120 is rotated so that the door 20 is completely closed.

Therefore, in the state in which the door 20 is closed, the door 20 is not opened without the force generated by the guide pin 121 over the floor 147 while the rotary shaft 120 rotates. The method of using the mitigation device can solve the problem of insufficient closing of the door.

The opening operation of the door 20 proceeds in the reverse order of the closing operation described above. When the user pulls the door 20, the pressure cam 140 is moved by the rotation of the rotation shaft 120. 140 is moved while reducing the compression force of the spring (130). Since the guide pin 121 of the rotating shaft 120 is located in the valley 145 past the cam surface 143, the fully open state of the door 20 is completed.

As in the closing operation process of the door 20, in the opening operation process, the self-gravity of the door 20 is positioned while balancing the compression force (elastic force of the spring) for the pressure cam 140 to compress the spring 130. Accordingly, it is possible to maintain the open state of the door 20 (maintain the current opening angle).

On the other hand, it is preferable that the guide groove 115 is formed on the outer circumferential surface of the housing so that the door frame 210 can be slide guided to 90 degrees in the door closed state.
