US 6,615,450 B2 · Apparatus for the damping of impacts, preferably the impacts of furniture doors or drawers

Abstract

An apparatus for the damping of impacts, preferably the impacts of furniture doors or drawers, consists of a cylinder with a piston whose piston rod sealingly guided out of a cylinder side forms a ram absorbing the impacts which divides the cylinder space filled with a liquid into two chambers and has perforations and/or, together with the cylinder wall, bounds a passage gap. A guide bushing guiding the piston rod is arranged in the region of the discharge end of the cylinder. A compression spring is clamped between the piston and the cylinder bottom. To ensure a smooth and quiet running with a compact construction, the guide bushing has a central shaft part of reduced diameter. A widened end part of the guide bushing is supported on a step or annular flange constricting the inner diameter of the cylinder and the guide bushing is supported at the other end on a cover closing the cylinder. The shaft part of the guide bushing is encompassed by a tube-section-like part made of elastic material.

Dependent claims

An apparatus for damping impacts of furniture doors or drawers comprising:

a cylinder having an open end and a closed end and divided into two chambers by a conically-shaped annular flange constricting the inner diameter of the cylinder such that the chamber at the closed end has a smaller diameter than the chamber at the open end;
a piston in the closed end of the cylinder and having a piston rod sealingly guided out of the open end of the cylinder;
a compression spring in the closed end of the cylinder;
a cover closing the open end of the cylinder;
and
a guide bushing arranged in the chamber at the open end of the cylinder and guiding the piston rod, said guide bushing having a central shaft part of reduced outer diameter, a first widened end part supported on said conically-shaped annular flange and a second frusto-conically widened end part that engages into a complementary borehole in said cover, said shaft part being positioned between said first and second widened end parts and enclosed by a tubular section part made of an elastic material.
