Abstract
A damping device for movable furniture parts, such as doors or drawers, includes a cylinder filled with a free-flowing medium which is compressed by a piston which has a spring applied to it in its extended position. In order to provide a damping device of this type of smaller length, the cylinder includes a telescopic cylinder having at least two stages. A pressure spring is clamped between the bottom of the outer cylinder of the last stage and the piston of the first stage.
Claims21
A damping device (1) for movable furniture parts (3), comprising
- a cylinder filled with a free-flowing medium which is compressed by a piston (8) which has a spring (13) applied to it forcing it into its extended position,
- characterized in that
- the cylinder is a telescopic cylinder (6, 7, 8) having at least two stages including a main outer cylinder (6), a first movable cylinder (7) movably guided in the main outer cylinder (6), and the piston (8) movably guided in the first movable cylinder (7) with respect thereto,
- the spring (13), which is a pressure spring, is clamped between a bottom (11) of the main outer cylinder (6) of a last stage and the piston (8) of a first stage, and p1 the first movable cylinder (7) is movably guided with respect to the main outer cylinder (6), and
- the piston (8) is movably guided with respect to both the main outer cylinder (6) and the first movable cylinder (7).

- the cylinder is a telescopic cylinder (6, 7, 8) having at least two states including a main outer cylinder (6), a first movable cylinder (7) movable guided in the main outer cylinder (6), and the piston (8) movably guided in the first movable cylinder (7) with respect thereto,
- the spring (13), which is a pressure spring, is clamped between a bottom (11) of the main outer cylinder (6) of a last stage and the piston (8) of a first stage.
- the piston (8) and first movable cylinder (7) are each provided with a flanged edge, each of which, in the extended position of the telescopic cylinder, press against annular collars (9, 20), provided on outer ends of the main outer cylinder (6) and the first movable cylinder (7) and narrowing their diameters, and
- the free-flowing medium is air, seals are inserted into annular grooves of the flanged edges, and the piston (8) of the first stage is provided with an axial ventilation bore (29, 30).
