Embodiment Construction

[0030] corresponds to Figure 1 to Figure 10 The cushioning device consists of a sleeve-shaped hydraulic cylinder 1 made of metal, or an injection-cast part made of plastic, which has a part 2 with a larger diameter at its open end, which is passed through a chamfer The annular step 3 is combined with a portion 4 of smaller diameter. The sleeve-shaped hydraulic cylinder is closed at its bottom and has a support 5 protruding upwards from the bottom and forming a fixed part of a compression spring 6 . A replaceable piston 7 is placed in said smaller diameter cylinder part 4 , the upper end face of said piston 7 being supported on a flat head 8 at the inner end of the piston rod 9 . The piston rod 9 is guided in the guide bush 10 , which is supported in a sleeve-shaped cover 11 closing the hydraulic cylinder 1 . Said piston rod 9 passes through a bore 12 in the cover 11 to the outside and has at its free end a cap 13 of flexible or elastic material fastened thereto.

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.

Description

technical field [0001] The invention relates to a device for damping shocks, in particular for doors or drawers of furniture, said device comprising a hydraulic cylinder with a piston which can be led out of Impingement piston rod that divides the fluid-filled cylinder space into two chambers and has holes and / or delimits a passage gap with the cylinder side walls; one mounted in the cylinder outlet end area and facing the piston rod a bushing that acts as a guide; and a compression spring that is clamped between the piston and the bottom of the cylinder. Background technique [0002] This type of mitigation device is generally complex in structure, or large in size, or cannot guarantee smooth and quiet operation. Bubbles in the damping fluid can cause jerky running and starting noises. Contents of the invention [0003] It is therefore the object of the present invention to provide a damping device of the type mentioned at the outset, which ensures smooth and quiet oper...
