Abstract

Disclosed herein is a door hinge device for absorbing the closing impact of a furniture door, which is adapted to minimize a work load and the number of work processes thereof according to assembly and disassembly thereof through the modification of a retaining structure thereof. The door hinge device includes a furniture hinge 10, a damper adapter 20 and a covering member 30. According to the present invention, since the assembly and disassembly of the door hinge device can be performed in a one-touch manner through the interaction between the damper adapter and the covering member, a convenience of the operation according to the assembly and disassembly of the door hinge device is improved, a work load is reduced, and a safety accident such as injury of hands and the like is prevented.

Claims

1. A door hinge device for absorbing the closing impact of a furniture door, the door hinge device comprising:

a furniture hinge (10) adapted to hingeably interconnect a side wall (W) of a piece of furniture and a furniture door (D) and having a retaining aperture (14) formed thereon;

a damper adapter (20) mounted to the furniture hinge (10) and having a fluid damper (21) built therein for absorbing the closing impact of the furniture door (D), the damper adapter (20) having a fixing hook (100) next to and a pair of clearance hooks (200) protrudingly formed downwardly from the underside thereof so as to be fittingly coupled to the retaining aperture (14), wherein the fixing hook (100) is disposed next to the clearance hooks (200) and a plurality of clearance spaces (300) are defined between the fixing hook (100) and each of the clearance hooks (200); and

a covering member (30) mounted on the damper adapter (20) and having a plurality of coupling protrusions (400) formed on the underside thereof so as to be fit into the clearance spaces (300) via a through-hole (500) of the damper adapter (20),

wherein the clearance hooks (200) of the damper adapter (20) are oriented toward the coupling protrusions (400) of the covering member (30) so as to be fixed by the retaining aperture (14).

2. The door hinge device according to claim 1, wherein the clearance hooks (200) are formed at the same side or the opposite sides of the fixing hook (100) along a width direction of the damper adapter (20).

3. The door hinge device according to claim 1, wherein the clearance hooks (200) are formed at the same side or the opposite sides of the fixing hook (100) along a lengthwise direction of the damper adapter (20).

4. The door hinge device according to claim 1, wherein each clearance space (300) is formed to have a width corresponding to the thickness of each of the coupling protrusions (400).

5. The door hinge device according to claim 1, wherein each of the clearance hooks (200) has a retaining jaw (210) integrally formed at the bottom portion thereof in such a fashion as to extend outwardly from an outer wall of the bottom portion thereof so as to be fixedly retained by a flange portion (14a) of the retaining aperture (14).
