Definitions
- Damper for a fitting for the movable mounting of a pivoting element or a pull-out element
- the present invention relates to a damper for a fitting for the movable mounting of a pivoting element or a pull-out element, in particular for the movable mounting of a piece of furniture, a window or a door, relative to a stationary support, comprising:
- At least one, preferably ring-shaped, sealing element which bears or can be laid against at least a first portion of an inner wall of the fluid chamber.
- the invention relates to a fitting with at least one damper of the type to be described, the fitting being designed in particular as a hinge, as a furniture drive or as a drawer pull-out guide for moving a movable furniture part.
- dampers are used, for example, to dampen the movement of pivoting elements or pull-out elements (e.g. drawers, doors, flaps or windows) or of movably mounted furniture fittings, so that loud slamming and damage to the pivoting elements or pull-out elements is prevented.
- the damping effect of a damper is generated by the flow resistance of a damping fluid located in a damper housing. When pressure is applied, the piston is displaced within the fluid chamber, with the damping fluid flowing from the high-pressure side to the Low-pressure side flows.
- damper chattering can occur.
- the damping fluid can no longer flow to a sufficient extent through the piston or past the piston.
- the increased pressure can then no longer be reduced by the damper, so that the piston and the piston rod attached to it come to an abrupt standstill or spring back.
- the damper housing can burst open due to the increased pressure and the hydraulic damping fluid can escape from the damper housing.
- AT 10 342 U1 shows a furniture damper with a cylinder and with a piston that can be displaced in the cylinder, the piston having at least one overload opening for the passage of a damping fluid.
- a closure element that can be displaced relative to the piston is provided, by means of which the overload opening of the piston can be closed at the start of the damping stroke.
- the damping fluid can only flow through between the piston and an inner wall flow through the annular gap formed in the cylinder.
- the closure element With increasing pressure, the closure element is expanded radially, so that the annular gap is reduced and the flow resistance for the piston is increased.
- the closure element can be stretched in the radial direction until the overload opening of the piston is released and a rapid reduction in pressure is brought about in the cylinder.
- a disadvantage of AT 10 342 U1 is that the annular closure element has a material cross-section which defines both the expansion properties and the rigidity of the closure element. If the material of the closure element is made too soft, the closure element can rest sufficiently against the inner wall of the cylinder, but the overload opening of the piston is then also opened too quickly. If the material of the closure element is made too hard, then the closure element only contacts the inner wall of the cylinder to an insufficient extent, with the overload opening of the piston being opened too late.
- a further disadvantage can be seen in the fact that production tolerances that occur on the inner wall of the cylinder and in the area of the overload opening can only be insufficiently compensated for by the annular closure element. Overall, the damper's range of applications is limited.
- the object of the present invention is therefore to specify a damper of the type mentioned at the outset while avoiding the disadvantages discussed above. According to the invention, this is achieved by the features of patent claim 1 . Further advantageous embodiments of the present invention are defined in the dependent claims.
- the at least one sealing element has at least one, preferably essentially annular, second section, which is spaced apart from the inner wall of the fluid chamber and which, when a damping stroke is performed above a predetermined threshold value, exerts pressure on the piston relative to is movable, preferably pivotable, tiltable and/or radially expandable with the first section that rests or can be placed on the inner wall of the fluid chamber.
- the at least one sealing element has a first section, the first section lying against an inner wall of the fluid chamber for sealing the fluid chamber or being able to lie against an inner wall of the fluid chamber when a damping stroke is carried out.
- the sealing element also has a second section, which can be moved, pivoted, tilted and/or radially expanded relative to the first section above a predetermined threshold value of a pressurization of the piston.
- the second section of the at least one sealing element can be pivoted in the direction of the inner wall of the fluid chamber above the predetermined threshold value of the pressurization on the piston, can be tilted and/or radially expanded, at least one overload channel, preferably arranged in the piston, being openable.
- the at least one overload channel which is preferably arranged in the at least one piston, can be covered by the second section of the at least one sealing element during the execution of a damping stroke below the specified threshold value of the pressure application on the piston and above the specified threshold value of the pressure application on the piston by the second Section of the at least one sealing element may be at least partially released.
