Claims

[Scope of utility model registration request]

A torsion spring 5 is wound around a pin 4 installed on the side wall 3 of the fixed frame 2 attached to the fixed wall 1, and a torsion spring 5 is pivoted around a pin 6 installed on the side wall 3 of the fixed frame 2 at one end. A lever 7 having a locking piece 8 that locks one end and rollers 11, 11 that press one end contact surface 10.10 of the first link 9 at the other end, and a lever 7 that is embedded in the door 12. A first link 9 pivoted to a pin 14 installed on the member 13 and a pin 15 installed on the side wall 3 of the fixed frame 2, a pin 16 installed on the embedded member 13, and a side wall 3 of the fixed frame 2. The lever 7 receives rotational torque about the pin 6 by applying pressure to the locking piece 8 of the lever 7 by the torsion spring 5. Pressure is applied to the joint surface 10 at one end of the first link 9 by the roller 11 of the lever 7 to close the first link 9.
By applying rotational torque around the pin 15, not only does it become an automatic sieve when the opening angle of the door approaches 60 degrees when the door is closed, but as the opening angle decreases, the catching force is gradually increased to increase the catching force when the door is closed. A hinge that is characterized in that it is designed to have a maximum value of 100%, and to hold the door when it is fully opened.
