초록 ▼

A gravity door hinge in which a cam is inserted non-rotatably into the lower half of a socket provided in a fixed member, the upper end of an axial rod is inserted non-rotatably into an axial bore hole provided in a rotational member, a cam follower is fitted rotatably around the middle of the axial rod by inserting the axial rod through a central hole bored in the cam follower, the lower half of the axial rod is inserted rotatably into an axial hole formed by hollowing out the center of the cam, the cam follower is fitted rotatably into the upper half of the socket, on top of the cam housed in the lower half of the socket so that an inclined cam surface formed on the lower end of the cam follower comes into close contact with an inclined cam surface formed on the upper end of the cam, and the base of the socket is completely closed. This gravity door hinge is very advantageous inthat any abrasion due to the off-center loads caused by the door opening and closing operations or the adhesion of dust can be effectively prevented, resulting in a prolongation of the life of the inclined cam surface of the cam follower, etc. This gravity door hinge also ensures the smooth operation of the door.

대표청구항 ▼

A gravity door hinge by which a door can be closed automatically by its own weight, comprising: a cam having an inclined cam surface on the upper end thereof, said cam being inserted nonrotatably into a lower portion of an upward-opening socket which is provided in a fixed member, said cam having a horizontal seating surface at the upper part of the inclined cam surface; an axial rod having its upper portion inserted nonrotatably into an axial hole provided in a rotational member; and a cam follower which has an inclined cam surface on the lower end thereof, said cam follower being fitted nonrotatably around said axial rod by said axial rod being inserted into a central hole in said cam follower, so that said cam follower is located at a substantially middle position on said axial rod, the lower portion of said axial rod being fitted rotatably into an axial hole formed in the center of said inclined cam surface of said cam, so that said cam follower nonrotatably attached around said axial rod is inserted into and contacts directly the upper portion of said socket on top of said cam housed in the lower portion of said socket, and so that said inclined cam surfaces of said cam and said cam follower are in close contact with each other, said cam follower having a horizontal seating surface at the lower part of the inclined cam surface, and wherein said rotational member is provided on the lower end thereof with a recess sized for receiving the upper part of said cam follower, said recess being formed concentric with said axial hole in said rotational member, said cam follower upper end being inserted into and closely fitted in said lower recess of the rotational member, and said upward-opening socket being formed so that the base thereof is completely closed.
