  • Patent number: 10233684
    Abstract: A furniture hinge mounted between a furniture wall and a furniture door so as to be used as an opening and closing mechanism of the furniture door, in which, by using the movement part provided on the body part of the furniture hinge and the adjustment part provided at the movement path of the movement part, the entire length of the furniture hinge is changed by advancing and returning the movement part in the opening and closing process of the furniture door such that, since the furniture wall and the furniture door do not come into contact with each other even though the furniture door is completely opened, the peeling damage to the exterior of the furniture is prevented and contact noise is eliminated, thereby improving the satisfaction of consumers.

  • Patent number: 10094157
    Abstract: A shock-absorbing damper for absorbing the impact force generated during the opening/closing of a furniture door, the damper including: a load pin in a housing to move back and forth during the opening/closing of the furniture door; a main valve coupled to the load pin to form a first flow path; a check valve coupled to a guide bar of the main valve in a manner to form a second flow path; a guider coupled to the main valve to guide the fluid flow; and a pressure adjuster interposed between the main valve and the check valve to vary the first flow path. The pressure adjuster and the guider are provided in the shock-absorbing damper to vary a flow path corresponding to an opening/closing load of the furniture door, thereby opening/closing the furniture door at a set speed regardless of the size or weight.

  • Patent number: 7845050
    Abstract: A device for buffering the closing impact of furniture doors is disclosed. A valve (40) is mounted around a piston rob (23) of a piston (20) in such a fashion that an oil gap (41) is defined between the outer peripheral surface of the valve (40) and the inner peripheral surface of a cylinder (10), the valve having a recessed oil passageway (47) formed on an axial end surface. A protrusion element (50) has a plurality of oil grooves (51) A check valve (60) slides reciprocally along the compression direction of oil. When an external load is exerted to the piston (20), a check valve (60) moves along with the protrusion element (50) and simultaneously oil contained in the oil chamber (11) flows through the recessed oil passageway (47) via the oil grooves (51) defined between the protrusion element (50) to absorb an impact generated during the closing of the furniture door.

A protrusion element (50) is integrally formed with a front end portion of the valve (40). The protrusion element (50) has a plurality of oil grooves (51) formed longitudinally on the outer periphery thereof. A check valve (60) is mounted on the outer circumferential surface of the protrusion element (50) in such a fashion as to slidingly reciprocate along the compression direction of oil.

  • Patent number: 7712185
    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.
