The present invention relates to a door hinge attachment damper, and more particularly to a door hinge attachment that is formed to be attached to the door can be attached to the door damper to mitigate the impact to the damping function even greater impact It's about damper.

Generally, a door that can be opened and closed by a spring hinge is installed in a furniture or a sink, and when the door is opened and closed, the door hits the frame of the furniture and a loud noise is generated. In particular, when children close the door inadvertently, not only the loud noise is generated, but also the risk of safety accidents, such as furniture is damaged.

In order to solve this problem, by installing a damper on the frame of the furniture to reduce the impact when the door is closed to reduce the occurrence of noise, the furniture is installed so that the furniture is not damaged.

In the conventional furniture dumper, as shown in FIG. 19, a hole is formed at a position far from where the door hinge is mounted to insert a cylindrical damper 1, or a separate holder 2 is installed.

The reason why the damper is mounted as far as possible from the door hinge is that the door closing force acts the farthest from the door hinge, that is, at the end of the door. This is because the shock can be absorbed with the smallest force.

If the damper gets closer to the door hinge at the furthest distance from the door hinge, the action of the closing force of the door is increased by the changed distance, so the damper must absorb the shock with that much force.

However, since the damper is formed in a circular shape as described above, the size of the furniture cannot be extremely limited by the frame of the furniture, and thus it is impossible to absorb such a large impact, thereby limiting the installation position of the damper.

In addition, because the damper protrudes on one side of the frame of the furniture for the above reasons, the appearance is not good, and because the damper protrudes while the door is open, it is easily broken when the force is applied from the side, or the holder is broken. There was a problem.

The body 100 and the cover 150 prepared as described above are fused at high frequency to the stepped portion of the fixing part 108 of the body 100 and the front end of the cover.

Thereafter, oil is injected into the body 100 and the cover 150 which are fused at a high frequency through a hole formed in the rear center of the cover 150, and the rod 160 has a rod fixing tool 124a of the piston support 124. Inserting and fixing to the damper 500 is completed.

The damper 500 is inserted into the adapter 200. The rod 160 protruding from the rear of the damper 500 is inserted to reach the inner wall of the rear of the adapter body 230, and the body of the damper 500 is inserted into the adapter 200. The transfer jaw 103 of the 100 is formed to be inserted into the guide part 222 of the auxiliary support part 210 of the adapter 200.

At this time, when the damper 500 is pushed backward, the transfer jaw 103 is transferred to the damper 500 along the guide portion 222, so that the rod 160 is inserted into the damper 500. That is, as the rod 160 is inserted, the piston support 124 pushes the piston 120, and the spring support 122 compresses the spring 112.

As described above, the damper 500 coupled to the adapter 200 is coupled to the hinge portion 300 as shown in FIG. 17, and a locking jaw 220 formed at the front lower end of the auxiliary support 210 of the adapter 200. , Using the engaging jaw 220 formed on the front lower end of the adapter body 230. That is, after hanging the end of the hinge portion 300 to the locking jaw 220 formed at the front lower end of the adapter body 230, the locking jaw 220 formed at the front lower end of the auxiliary support 210 of the adapter 200. Coupling to the coupling groove (not shown) formed in the hinge portion 300.

As described above, the hinge unit 300 to which the damper 500 is coupled may be installed in a door or installed inside a furniture as shown in FIG. 18. The hinge part 300 installed in the door or furniture is coupled to the hinge operation part 312 and is coupled to the hinge part 310 installed at a corresponding position of the hinge part 300 and the furniture.

Referring to the operation of the damper 500 installed as described above, it can be described by dividing into three cases when the door is opened, the door is closed slowly and the door is suddenly closed. Hereinafter, a description will be given with reference to FIGS. 14 and 15.

1) When the door opens

  When the door is opened, the damper 500 is inserted into the adapter 200 and then returned to the front by the spring 112. At this time, the oil inside the body 100 moves from the BB zone to the AA zone. .

The oil in the BB region passes through the passage passage hole 124e of the piston base 124 through the case passage hole 130d of the sponge case 130 and passes through the passage hole 12b of the piston 120. After that, it flows into the AA section.

If the body 100 moves and the piston 120 reaches the flow path adjusting groove 114 of the spring guide 110, the oil in the AA zone directly flows through the flow path groove 214e through the flow path adjusting groove 114. Will flow into.

2) The door closes slowly

   When the door closes slowly, the hinge operating portion 312 presses the hinge induction jaw 102 so that the damper 500 is inserted into the adapter body 230 of the adapter 200, wherein the rod 160 is damper 500. ) And the oil moves from the AA zone to the BB zone.

The oil in the AA zone flows through the flow path through hole 214e along the flow path groove 124c through the flow path hole 120b formed at the center of the piston 120, and then the case flow path hole of the sponge case 130. Through the 130d, the sponge 132 flows, and the oil flows through the flow path adjusting groove 114 of the spring guide 110 to the flow path through-hole 214e.

If the body 100 moves and the piston 120 reaches a point where the flow path adjusting groove 114 of the spring guide 110 ends, the oil flows through the flow path adjusting groove 114 of the spring guide 110. It is blocked and flows only through the flow path hole 120b formed at the center of the piston 120. This reduces the flow of oil into the deceleration section so that the door closes slightly when it closes.

3) The door closes suddenly

  When the door is suddenly closed, the hinge operating portion 312 is pressed while applying a shock to the hinge induction jaw 102, the damper 500 is inserted into the adapter body 230 of the adapter 200, wherein the rod ( 160 is inserted into the damper 500, the oil is moved from the AA zone to the BB zone.

The flow of oil flows in the same manner as in the case of 2), but when it is subjected to a large impact at first, the outer circumference of the flow path hole 120b of the piston 200 is caused by the inertia force as shown in the enlarged E of FIG. 124d) may not only reduce the inlet of the flow path 120b but also block a part of the flow path groove 124c flowing through the flow path hole 124e, thereby rapidly reducing the flow of oil, thereby absorbing a large shock.

As in the case of 2), the flow of oil is such that the oil flows to the deceleration section after the body 100 moves so that the piston 120 ends the flow path adjusting groove 114 of the spring guide 110 so that the door is almost closed. When it closes, it closes slightly.

By forming the shape of the damper 500 in the shape of a rectangular box with corners, it is possible to widen the area of the piston that can absorb the shock, so absorbs more than three times the impact of the circular damper 500 even in a very large impact It can be made small and its size can be attached to the door hinge.

As described above, according to the door hinge attachment damper of the present invention, the body can be attached to the door hinge by forming a box-shaped weave with corners to absorb a greater impact, so that even after the installation of the damper There is an effect that does not damage the appearance, the damper is not easily damaged, there is an effect that can significantly reduce the noise by the deceleration section by forming a damping section and a deceleration section.
