Definitions

  • the present invention relates to a slat blind according to claim 1.
  • Slat blinds or Rafflamellenstoren are well known.
  • conventional slat blinds the slats of a slat hanging can be raised and lowered and formed tiltable.
  • the lifting and lowering takes place via an elevator belt to which the bottom slat or rail is fastened.
  • the elevator belt is lifted from a fully lowered slat curtain or rolled up onto a drum, the lowest slat gathers and laminates all the slats until the entire slat curtain is stacked and fully lifted.
  • lowering the slat curtain first the top slat is lifted from the stack, then the second highest slat, etc.
  • Such slats are usually by means of a vertical strand pair, which acts on the blade edges and is operatively connected to a rocker tiltable.
  • the rocker is driven, for example via a driving clutch, which cooperates with the drive motor for raising and lowering the Lamellenbehangs.
  • the EP 0 609 541 A1 discloses a lamellar store with a rocker and two associated pairs of strands, which are arranged at a distance from each other, measured in the longitudinal direction of the lamellae.
  • the strands of the strand pairs are each attached to attachment points on the longitudinal edges of the slats.
  • the slat hanging can be raised and lowered by means of the elevator belts.
  • the distance between the outer lamellar edges is greater than the distance of the respective inner lamellar edges between all slats. This is achieved by making the distance, measured in the vertical direction between two successive attachment points of the outer strands, greater than the corresponding distance between two successive attachment points on the inner strands.
  • the aforementioned slatted blind can also be designed in a known manner as a safety slat blind which is constrained, so that it can not be opened from outside a building or window.
  • the slat blind according to the invention has a slat curtain which has a plurality of slats arranged one above the other.
  • Each blade has two ends, a first and a second end, wherein these two ends are arranged opposite each other in the longitudinal direction.
  • a first end region of the lamella connects to the second end and a second end region of the lamella.
  • the sipe gate further includes a first winding mechanism and first rocking mechanism cooperating with the first end portion of the sipes.
  • the lamellar store has a second drive mechanism and second luffing mechanism cooperating in the second end region of the lamellae, which is spaced apart from the first end region in the longitudinal direction of the lamellae, tilting axes parallel to the longitudinal direction and preferably extending through the middle of the lamellae during lifting and lowering of the lamellar curtain follow a trajectory.
  • the lamellar store also has at least one electric drive motor, which drives the elevator mechanisms synchronously for raising and lowering the lamellar suspension and for tilting the lamellae, the luffing mechanisms.
  • the lamellae are designed to be twistable about their associated tilting axes and the first and the second luffing mechanism can be driven independently of one another in order to twist the lamellae.
  • the incidence of light can be adjusted along a horizontal region of the Lamellenbehangs. If the slats are twisted, then the lamellae is divided into a translucent area and in an opaque area. In the translucent area, with maximum light transmission, the lamellae or the lamellar surfaces are aligned at least approximately horizontally or at least approximately at right angles to the movement path, which corresponds to an open position of the lamellae. In the light-impermeable region, the lamellae are aligned at least approximately vertically or at least approximately parallel to the movement path, which corresponds to a closed position of the lamellae.
  • Both sides adjustable and arbitrary selectable intermediate positions between closing and open position of the slats are possible.
  • the transition seen in the longitudinal direction between the two areas is fluid, that is, the lamellae twist continuously starting from the open position, in which one end portion in a closed position at the other end.
  • a person who is in a room for example, adjust the light of day or outside light, so that this person is not disturbed by the light and yet no artificial electricity generated by light in the room is needed.
  • the person may or may not illuminate the part of the room that is not being used, as desired, by daylight or outdoor light.
  • first elevator mechanism and the first rocking mechanism are driven by the drive motor and the second elevator mechanism and the second rocker mechanism are driven by another drive motor.
  • the two drive motors are controlled by a controller so that when synchronized control of the drive motors, the slats raised, lowered and tilted and can be wound with individual control.
  • the selected design of the drive by means of two drive motors and the use of a controller the operation of the slat blind is greatly simplified.
  • the control can be programmed accordingly, so that the slat blind is easy to operate.
  • the function "tilting slats” is achieved via the actuation of the first or the second operating element, as is the case with known slat blinds.
  • the lamellae are made of a resistant, flexible, in particular elastic material.
  • the drives or actuators for controlling the Wippmechanismen not be so strong.
  • the lamellae should be resistant to fatigue on repeated twisting. To achieve this, various materials such as plastic, sheet metal, aluminum or composite materials come into question.
  • the lamellae preferably have a flat profile formed without ribs, which for example has an arcuate shape in cross-section or is slightly curved. Furthermore, the lamellae preferably have no edge flanging.
  • the slats are guided or held on both sides at the ends.
  • the lateral guide is preferably formed directly or indirectly by means of guide rails.
  • a lateral guide prevents the slats and thus the slat curtain from dodging in a horizontal direction when twisted or tilted.
  • this has the advantage that the lamellar store can be arranged on a building exterior side and so the weather, in particular the wind, can be suspended. Such slat blinds must also withstand storms and fluctuating temperatures.
  • the blades are arranged at an equidistant distance from each other during lifting and lowering.
  • the slats can preferably only be tilted and twisted when the slat curtain is completely lowered.
  • Lamellenstoren in such a way that they are arranged equidistant from each other.
  • the elevator and Wippmechanismen are always synchronously driven in these known safety slats or slats blinds.
  • the equidistant distance has the advantage that when twisting the slats, these can not touch each other, whereby no damage to the slats is possible and no friction occurs.
  • a rocker arm is arranged at each of the ends of the lamellae, the free ends of all luffing levers associated with the first end region being guided in a first rocker rail running parallel to the movement path and the free ends of all luffing levers corresponding to the second end region are assigned are guided in a parallel to the trajectory extending second rocker rail.
  • the rocker rails are, preferably parallel to each other, away from the movement path and on the movement path to the slats at synchronous Move the rocker rails of the rocking mechanism to tilt and, when moving, to twist only one of the rocker rails.
  • the first rocker mechanism has per each lamella on a rocker arm, which is connected to the associated first end of the blade and a respective first rocker rail.
  • the second rocker mechanism also has per lamella each a rocker arm which is connected to the associated second end of the blade and a second rocker rail through the use of a rocker rail and guided therein with their free ends rocker arms, the construction of the rocker mechanism 'relatively simple and thus durable.
  • the rocker mechanism can also be actuated by one or more separate actuators, independently of the two drive motors already described, due to the selected design. When using actuators, it is possible to use only one drive motor, which drives the two elevator mechanisms.
  • the rocker rail and the rocker arm also allow the transmission of a relatively large force on the slats. Even if the lamellae are made of relatively stiff material, twisting is possible due to the selected design of the luffing mechanism.
  • the first and second elevator mechanism each have an endless chain and a respective scissor chain.
  • the endless chain passes over a lower and an upper sprocket, wherein one of these sprockets is connected to the associated drive motor.
  • the endless chain is connected to a carriage and the carriage is movable up and down along the path of travel by means of the endless chain, with one end a scissor chain is mounted on the carriage and another end of the scissors chain is mounted in the vicinity of a sprocket stationary.
  • the lamellae are mounted on hinge points of the scissor chain so that the tilting axes run through the hinge points. In this case the trajectory is defined by the points of articulation.
  • the described design of the elevator mechanisms is a positive guidance of the slats or the Lamellenbehangs.
  • the slats are stably guided and can thus protect a window or an entrance area from vandalism and burglary.
  • the scissor chain Due to the arrangement of the slats on the hinge points of the legs of the scissor chain, the slats move when lifting and lowering centered and equidistant along the trajectory. Furthermore, the scissor chain has the advantage that the lamellae can not move in the horizontal direction or in the vertical direction when the circulating chain is stationary and braked. If the rocker mechanisms are activated, the lamellas can be tilted (synchronous drive of the rocker mechanisms) or twisted (one-sided drive of one of the rocking mechanisms).
  • the carriage moves, preferably by means of a Umhebhebels, in a lower end region of the movement path, the rocker rail along a backdrop, parallel to itself to tilt the slats from an open position to a closed position.
  • a driver is attached to the endless chain, and this driver is guided in a recess of the along the trajectory up and down movable carriage, wherein the recess in the carriage is formed so that the car, or the driver, at fully extended slat hanging is blocked.
  • the follower In the lowermost, fully extended position of the slat curtain, the follower is located at the lowest point of the endless chain at the periphery of the lower sprocket.
  • the recess in the carriage may be formed such as arcuate that the driver can run along a first run of the endless chain in the direction of the lower sprocket, while the carriage moves in the direction of the lower sprocket, wherein subsequently the Driver can run around the lower sprocket around and then along a second run of the endless chain can move back in the direction of the lower sprocket away while moving the car again, also in the direction of the lower sprocket away.
  • the direction of rotation of the endless chain need not be reversed in order to lower the lamellar store and then lift it again.
  • the drive direction of the endless chain is formed reversible.
  • all the slats are tilted from the open position into a closed position when the first and second elevator mechanisms are lowered synchronously, while in the lower end region all the slats of the slat curtain are tilted from the open position. With subsequent one-sided lifting in the end of one of the elevator mechanisms, the slats are wound.
