Embodiment Construction

[0040] In such figures, the damping device according to the invention is indicated generally by the reference numeral 100 .

[0041] Shock absorbing device 100 (FIG. 1) mainly includes: housing 1; cover 2, which basically closes housing 1 and forms a seal with the inner surface; piston 3, which is slidably installed inside housing 1; Piston 3 is connected to reset element 6 .

[0042] The housing 1 ( FIGS. 2 and 3 ) is preferably cylindrical and has a closed first longitudinal end 1 a and a second longitudinal end 1 b which is open to allow the piston 3 and 1 other components inside can be inserted. After assembling such an assembly, a cover 2 is applied on the longitudinal end 1b. At the longitudinal end 1 a inside the housing 1 , a protrusion 11 is formed which forms an abutment with the piston 3 .

[0043] The housing 1 defines inside it a volume V suitable for housing the above-mentioned components and containing a viscous fluid acting as a shock absorber. Such viscous...

Abstract

A damping device (100), in particular to dampen impacts of mobile parts in pieces of furniture, comprises: a casing (1) containing a viscous fluid; a piston (3) slidably mounted inside the casing (1) and defining inside the casing (1) two regions with variable volume, which are in fluid communication at at least one duct defined in the piston (3) and at an hollow space defined between the outer surface of the piston (3) and the inner surface of the casing (1). The damping device (100) is characterised in that the piston (3) comprises a floating shutter (5) suitable for closing the at least one duct defined in the piston (3) during the working stroke of the piston (3) and for opening the at least one duct defined in the piston (3) during the reset stroke of the piston (3). The damping device (100) allows a substantial reduction in the reset force of the piston (3) to be obtained maintaining a particularly simple structure and low manufacturing costs.

Description

technical field [0001] The present invention relates to a shock absorbing device, in particular to a shock absorbing device for shock attenuation of movable parts in a piece of furniture. [0002] The invention also relates to a piece of furniture comprising such a damping device. Background technique [0003] In the field of furniture pieces of various types and uses, wherein said furniture pieces comprise movable parts such as sliding doors or drawers, it is known that Shock absorbing devices are used to attenuate the impact of such movable parts in the abutting position. The occurrence of shocks is unsatisfactory for the user and indeed impairs the functionality of the furniture piece in the long run. [0004] A type of shock absorber generally used for the above purpose is represented by a linear hydraulic shock absorber, which mainly includes a piston slidably mounted inside a housing containing a viscous fluid that performs a shock absorber effect. The piston define...
