Definitions
- the present invention relates to a door damper, which is attachable to a door hinge and which is to reduce an impact and perform a damping function when a strong impact is applied.
- furniture and kitchen units have a door that can be closed or opened using a spring hinge.
- big noise occurs because a door is slammed into a frame of furniture with a bang.
- bigger noise when children carelessly slam the door of the furniture.
- it can be very dangerous for the children and also the furniture can be easily damaged.
- a cylindrical damper 1 is inserted in a hole formed away from a door hinge or an additional holder 2 mounted on a frame of furniture.
- damper is mounted away from the door hinge with a maximum distance is that a minimum power can be used to absorb an impact when the impact is directly applied to the end of the door. Because the force of closing the door needs to be the strongest at end of the door, that is, a portion of the door furthest from the door hinges.
- the force of closing the door correlates in strength to the length that the damper moves. Consequently, the damper needs to absorb the impact with greater power.
- the damper is formed on a frame of furniture in a circular shape, the size of the damper is limited. Consequently, the damper can not handle a greater impact and also there is a limitation to change a mounting position of the damper.
- damper Since the damper is protruded from a side of frame in furniture, appearance becomes somewhat awkward. Moreover, the damper or the holder can be easily broken because the damper is protruded when door is open.
- a door damper comprising a piston type damper which is inserted in a guide part of an auxiliary supporting part of an adapter being mounted by means of at least two stoppers on a hinge fixing part.
- US 6,591,454 B2 discloses a hinge for pieces of furniture comprising a hinge arm and a hinge casing which are connected to each other by means of at least one hinge axel.
- the hinge arm is provided with a fluid damper.
- the fluid damper is mounted on the side of the hinge arm without the use of a tool.
- a door hinge attachable damper having a piston and a check valve in an oil chamber, and a rod inserted in the oil chamber so as to absorb an impact by controlling flux of flowing oil, is provided.
- the door damper comprises an adapter having an auxiliary supporting part which includes a guide part such that the damper is inserted and moved, and at least two stoppers so as to be mounted on a hinge fixing part.
- the damper includes a body having a rectangular shape, and an open rear side, a hinge guide stopper protruded on an outer upper surface, two spring guides protruded to an inside, and a conveying stopper on a side at a front lower end.
- the door damper comprises springs inserted into an inside of the body and coupled with the spring guides, respectively.
- the door damper further comprises a piston formed of a flexible material to closely contact an inner periphery of the body, the piston having a front side which is open to receive a spring holder and a piston holder which includes a rod fixing member, the piston holder being adhered on a rear side of the piston.
- the door damper comprises a sponge case installed together with the piston holder, having a front side in which a through guide fixing hole, a rod insert hole, and a case passage hole are formed.
- the sponge case has a rear side which is open such that a sponge is inserted into an inside.
- the door damper further comprises a packing formed of rubber for blocking the sponge case and an open entry at the rear side.
- the packing having a rod packing member formed at a center; a cover having one side which is open to block the open rear side of the body and having the other side in which a hole is formed at a center.
- the damper further comprises a rod fixed in the rod fixing member of the piston holder and formed to pass through the rod insert hole of the sponge case, the hole of the packing, and the hole of the cover so as to be protruded to an outside.
- the damper attachable to the door hinge according to the present invention can be attached to the door hinge to absorb greater impact energy. Accordingly, an appearance of the furniture is not disturbed by the damper although the damper is mounted, and the damper is not easily damaged. Furthermore, the damper according to aspects of the present invention includes a damping section and a deceleration section. Therefore, noise is dramatically reduced in the deceleration section.

- the packing 140 After inserting the fixing stepped end 110a into the guide fixing hole 130b, the packing 140 is inserted inside the cover 150, and the fixing part 108 of the main body 100 is inserted to the cover 150. At the moment, the end of the fixing part 108 is pressed to the adherent part 140a of the packing 140 to contact to the end of the fixing part 108 and the adherent part 140a.
- the fixing stepped end 110a and the front end of the cover 150 are fused using high frequency.
- the oil is injected inside the main body 100 and the cover 150 through a hole formed at a center portion of the rear side of the cover 150.
- the rod 160 is inserted and fixed in the rod fixing hole 124a of the piston holder 124. Finally, the damper 500 is completely assembled.
- Such a damper 500 is inserted to the adapter 200 to contact the rod 160 protruded from the rear side of damper 500 to an inside surface of the damper 500 and to insert the convey stopper 103 of the main body 100 in the guide part 222 of the auxiliary supporting part 210 of the adaptor 200.
- the convey stopper 103 When the damper 500 is pushed in a backward direction, the convey stopper 103 is conveyed along the guide part 222, and accordingly, the rod 160 is inserted to the inside of the damper 500. That is, the inserted rod 160 pushes the piston holder 124, and the pushed piston holder 124 pushes the piston 120. As a result, the spring holder 122 presses the spring 112.
- the damper 500 jointing to the adapter is coupled to the hinge fixing part 300 using the stopper 220 formed at a front lower portion of the auxiliary supporting part 210 of the adaptor 200 and another stopper 220 formed on the front lower portion of the adaptor body 230. That is, the end of the hinge fixing part 300 is hooked on the stopper formed on the front lower portion of the adaptor body 230, and the stopper 220 formed on the front lower portion of the auxiliary supporting part 210 is jointed to a connection groove (not shown) formed on the hinge fixing part 300.
- the hinge fixing part 300 hooked to the damper 500 may be installed at a door or an inside of furniture as shown in FIG. 18 .
- the hinge fixing part 300 installed the door or the furniture is jointed to the hinge 310 installed a corresponding predetermined location of the furniture to the hinge fixing part 310.
- the damper 500 inserted to the adapter 200 moves in a forward direction to be retuned to an original position by the sprig 112. While opening, the oil in the main body 100 flows from a BB section to an AA section.
- the oil in the BB section flows to the AA section passing through a case oil passage hole 130d of the sponge case 130, an oil passage hole 124e of the piston holder 124 and an oil passage hole 12B of the piston 120.
- the hinge operation part 312 pushes the hinge guide stopper 102.
- the damper 500 is inserted into the adaptor body 230. Accordingly, the rod 160 is inserted to the inside of the damper 500 and the oil moves from the AA section to the BB section.
- the oil in the AA section flows along the oil passage groove 124c through the oil passage hole 120b formed on a center portion of the piston 120 and the oil through hole 124c. After then, the oil flows to the sponge 132 through the case oil passage hole 130d of the sponge case 130. And then, the oil flows to the oil passage hole 214E through the oil passage control groove 114 of the spring guide 110.
- the hinge operation part 312 pushes the hinge guide stopper 102 with an impact, and the damper 500 is inserted into the adaptor body 230.
- the rod 160 is also inserted inside the damper 500 and the oil flows from the AA section to the BB section.
- the flow of the oil is identical to that of the case of slowly closing a door.
- an outer peripheral surface of the oil passage hole 120b of the piston 200 becomes closely adhered to the oil control groove 124d by the inertia force as shown as a dotted circle E in FIG. 14 .
- the entrance of the oil passage hole 120b become narrow and accordingly, the amount of flowing oil is suddenly reduced by blocking a predetermined portion of the oil passage groove 124c.
- the amount of the flowing oil is reduced after the piston 120 reaches the end of the oil control groove 14 of the spring guide 110, which is the deceleration section, to smoothly close the door.
- the damper 500 is formed as a rectangular shape having tapered corners in order to widen a size of the piston that absorbs the impact. Such a rectangular shaped damper 500 with round corners can absorb three or more times greater impact than a circular damper 500. And, it is easier to manufacture the rectangular shaped damper than the circular damper.
