Definitions
- the present invention relates to a roller blind device with a roller blind and a winding roller to which the Rollobann is attached and which is biased by spring force in the winding direction of the roller blind. Furthermore, the present invention relates to a vehicle roof with such a roller blind device.
- Roller blinds of the type mentioned are used for numerous applications, especially for shading purposes, for example, on buildings or in vehicle construction, but also as covers, for example in cabinets or chests, but also in vehicle especially as cargo space and trunk covers.
- the roller blind In order to activate such a roller blind device, the roller blind is unwound from the winding roller against the spring force of the winding roll and fixed in the at least partially unwound state, for example suspended. In order to subsequently open the blind again, the free end of the roller blind is unhooked, so that the roller blind automatically winds under the action of the spring force.
- DE 44 22 842 Cl damping elements have been proposed to decelerate the movement of a movable part. Similar to DE-U 92 03 450 here is a hollow chamber with a viscous material, in particular oil, filled to dampen the movement of a rotating in the hollow chamber member.
- pressure volume is generally equal to any pressure fluid, i. Liquid or gas could be operated, this is to make the structure as simple as possible, preferably operated with air.
- the volume of the drawer is preferably coupled to the free end of the roller blind web via a cable pull arrangement.
- a pressure is built up here via the cable arrangement in the pressure volume and the take-up motion is braked in an opposite movement of the roller blind.
- a pull bow is provided at the free end of the roller blind, by means of which the roller blind is provided for a uniform and flutter-free method.
- the roller blind rail guide rails can be provided laterally, in which the towing bar is guided directly or in which associated with the Switzerlandspriegel sliders are guided.
- the printing volume is provided by a pressure cylinder coupled to the free end of the roller blind, in which preferably a displaceable pressure piston is provided which determines the size of the pressure volume. If the free end of the same is moved when winding or unwinding the roller blind, then the pressure piston coupled to the free end, or a pull hoop provided thereon, or to the gliders connected to the pull hoop moves back and forth accordingly in the pressure cylinder.
- roller blind and pressure piston in principle can be done in any way, there is a particularly simple structure when the pressure piston coupled via a cable arrangement with the free end of the blind is.
- Suitable cables are any tensile, preferably tensile and compression-resistant, and yet preferably flexible elements, such as ropes, cords, wire ropes, chains and the like.
- the pressure piston arranged in the pressure cylinder could also be actuated by means of a coupled to the free end of the roller blind push rod.
- the roller blind device can in this case be designed such that the pressure piston is displaced during a winding movement of the roller blind web between a first end position, in which the pressure volume is minimal, and a second end position, in which the pressure volume is maximum.
- the arrangement may in this case be such that the damping of the winding movement of the roller blind is attenuated either by means of a negative pressure generated in the pressure volume or by means of an overpressure generated in the pressure volume.
- the roller blind device is preferably designed so that the pressure piston is in the first end position, ie in the position in which the pressure volume is minimal when the roller blind is unwound from the winding roller, so that the pressure piston when winding up the roller blind, when it is displaced in the direction of the second end position, generates a negative pressure by increasing the pressure volume.
- the pressure cylinder preferably has an air inlet opening and an air outlet opening provided with a one-way valve, the air inlet and outlet openings being arranged such that the pressure volume is vented via the air outlet opening when the pressure piston moves in the direction of the first end position wherein, during a displacement of the pressure piston in the direction of the second end position in the pressure volume, a negative pressure is generated by increasing the pressure volume into which no air can flow through the now closed one-way valve, and air can flow into the pressure volume through the air inlet opening, when the pressure piston reaches the second end position.
- the pressure cylinder ensures damping of the winding movement of the roller blind as soon as the roller blind is released from an at least partially unwound position, as the closed pressure volume is increased by the displacement of the pressure piston. Only when the second end position is reached, in which the blind is completely wound, air can flow through the air inlet opening in the pressure cylinder, so that the pressure volume is again pressure-free. Moreover, in this embodiment of the roller blind device, the damping of the winding movement increases with progressive movement of the roller blinds.
- the arrangement may be such that the pressure cylinder has an air passage opening which is arranged such that upon movement of the pressure piston in the direction of the second end position, the pressure cylinder is moved in the direction of the first end position. ie when unwinding de s blinds, air can flow through the air passage opening in the pressure volume, and upon movement of the pressure piston in the direction of the first end position, ie when winding the blinds, air can escape from the pressure volume through the passage opening.
- the air passage opening is dimensioned so that the amount of air flowing through the air passage opening per time is less than the amount of air displaced by the pressure piston (ie to produce a damping effect, the opening area of the air passage opening smaller
- the air passage opening will be small in comparison to the cross-sectional area of the pressure cylinder, wherein the degree of damping can be set as desired by dimensioning the air passage opening.
- the roller blind device is designed such that the pressure piston can be displaced by the cable pull arrangement in both directions, so that no pressure-resistant elements have to be provided as cable pull elements, but only tensile-resistant elements, such as For example, ropes can be used.
- a cable can in this case be fastened on both sides of the pressure piston, for example by means of hooks, or, in a preferred embodiment of the invention, penetrate the pressure piston.
- the pressure piston may have an axial slot in which the cable is inserted.
- the pressure piston can be fastened to the cable by means of clamping, gluing, welding, crimping and / or by separate holding elements.
- the rope through the pressure volume therethrough runs, it is understood that at the end facing away from the pressure piston end of the pressure volume, a corresponding sealing element should be provided to seal the moving rope relative to the impression cylinder.
- the pressure piston itself can be sealed in a manner known per se by means of seals running radially along the outside of the piston, for example O-ring seals, relative to the impression cylinder.
- a cable pull arrangement is used for moving the pressure piston, this may comprise a circulating cable, in particular a closed circulating cable, which is coupled on the one hand to the free end of the roller blind and to which on the other hand a pressure piston is attached.
- a compensating element such as a tension spring may be provided in the revolving rope.
- a pressure cylinder may be provided, which is articulated on both sides to the free end of the roller blind, in particular to a provided at the free end of the roller blind tension bow or connected to the tension bow slider.
- a separate pressure cylinder may be provided on both sides of the roller blind, the pressure pistons of which are each coupled to one end of the pull bar or one each to a slider connected to the pull bar.
