Abstract: A hinge damper is configured to be adhered to a door hinge of the furniture having a door to attenuate impact and is designed in a small size but to attenuate a large amount of impact. In the hinge damper, first and second seals are formed in an oil seal to prevent air from being introduced. A cross rib is formed on a piston to absorb a larger amount of impact with a small size. The hinge damper can be sized as small as a size of a screw used for fixing the hinge.

Abstract: Disclosed is a shock absorber for a drawer. The shock absorber includes a body filled with fluid, a piston member inserted into the body while being coupled with a rod, and a buffering member installed in the body to prevent the body from being broken by receiving pressure change of fluid when the piston member moves forward and backward. According to the shock absorber, high impact force generated when the drawer is closed can be absorbed and efficiently distributed, so that the drawer can be silently operated.

Abstract: Disclosed is a door damper, in which a safety check valve is installed in consideration of the case in which an impact exceeding a design pressure will be applied, thereby absorbing the impact to enable a door to be closed safely and smoothly. In the door damper, a safety check valve is installed in a piston, and thus is opened in cooperation with another check valve installed between a spring holder and the piston when the pressure exceeding a design pressure is applied. Thereby, when the impact exceeding the design pressure occurs, the safety check valve can absorb the impact to prevent damage. A channel can be adjusted by only ridges formed on an outer circumference of the check valve, so that productivity can be improved thanks to easy tolerance management. Further, an oil seal is not contracted or deformed in spite of long-term use.

Abstract: The present invention relates to a hinge damper and, more particularly, to a hinge damper that is configured to be adhered to a door hinge of the furniture having a door to attenuate impact and is designed in a small size but to attenuate a large amount of impact. In a hinge damper of the present invention, first and second seals are formed in an oil seal to prevent air from being introduced. A cross rib is formed on a piston to absorb a larger amount of impact with a small size. According to the present invention, the hinge damper can be small-sized while attenuating impact the present invention has been made. In addition, the hinge damper does not affect on the size of the hinge. Further, since the hinge damper can be identically sized to a screw used for fixing the hinge, it is not exposed to an external side.
