Abstract

Universal impact-hinder device, comprising a body (1); a guiding pin (4) arranged at the closed first end of an inside cylindrical cavity of the body (1), a spring (7) on the guiding pin (4); a ring (5) at the opposite end of the cavity; and a piston having T-shaped head and an inside cavity in which the spring (7) is supported, which piston can move until the ring (5), while the guiding pin (4) is within the inside cavity of the piston. The T-shaped head is provided with a groove and a movable O-ring (6) within that, having two end positions in the groove. In first end position a surface of the groove having artificial damages (31) and the contacting O-ring (6) determine a first flow-through capacity, in second end position an orifice (21) between the cavity of the body and the groove determines a greater second flow-through capacity.

Claims

1. Universal impact-hinder device, comprising a body (1);

a guiding pin (4) arranged at the closed first end of an inside cylindrical cavity of the body (1), a spiral spring (7) on the guiding pin (4);

a ring (5) at the opposite second end of the inside cylindrical cavity of the body (1); and

a piston having a T-shaped head in cross section and an inside cavity in which the spring (7) is supported, which piston is capable to move until the ring (5) within the inside cylindrical cavity of the body (1), while the guiding pin (4) is within the inside cavity of the piston, wherein the T-shaped head of the piston is provided with a groove and a movable O-ring (6) within that, where the O-ring (6) has two end positions in transversal direction of the groove, in the first end position a surface of the groove having artificial damages (31) and the contacting O-ring (6) determine a first flow through capacity, where pressing the O-ring (6) into the artificial damages (31) closes partially ducts of artificial damages (31) thus reducing the first flow through capacity, and in the second end position an orifice (21) between the inside cylindrical cavity of the body (1) and the groove determines a second flow through capacity which is greater than the first flow through capacity.

2. The device according to claim 1, wherein the piston of cylindrical inside cavity is made of two concentric parts fitted into each other, a first piston (2) and a second piston (3), where the groove of the piston are formed between the rims of first and second pistons (2,3).

3. The device according to claim 1, wherein the body (1) is provided with flat support flange for fixing to a furniture surface by gluing or screwing.
