Definitions

  • the present invention relates to a sun protection system with emergency lifting device, with an extendable curtain, which is movable via a drive device, wherein the Notraff worn has traction means by means of which the curtain can be pulled up from a lowered position.
  • a sun shading system with Notraffvorraum known in which the raising of the curtain, a gas spring is provided which drives a first tension element a pulley with a small diameter, which is coupled to a winding roller with a larger diameter. About the winding roll, a winding element is then wound up to pull up the Lamellenbehang. Due to the transmission ratio between the winding roller and the smaller pulley is achieved that the curtain is pulled up by the movement of the gas spring with high, if necessary. Increasing speed through the Notraff issued.
  • the DE 100 48 296 shows a sunshade system in which a curtain is adjustable via a pulley. By moving a part of the pulley the curtain can be moved in the normal operation.
  • the traction means of the emergency traction device are coupled to at least one damping element which dampens the movement of the curtain at least before reaching the raised end position of the curtain. This avoids that the material stress is too high by a sudden striking of the curtain when triggering the Notraff coupled and damage may occur. Because a regular release of the emergency equipment is already necessary so that the functionality is guaranteed. Such a check must therefore be carried out, the stress is now kept low.
  • the speed of the curtain can be set optimized, for example, the curtain can be moved faster in an initial phase than just before the end position.
  • the damping element is effective only at an end region in front of the raised end position, preferably 5 to 50% before the end position relative to the entire travel path. This ensures that, in spite of the damping when the emergency lift device is triggered, the curtain initially accelerates and hoists relatively quickly so that an escape route is released from the curtain. Only at the end of the movement, the damping element can develop its full effect, with an increase in the damping force at high speeds is possible.
  • a fluid damper in particular oil or gas damper used as a damping element, for example, a linear damper with a movable piston rod. Then, depending on the speed of the piston rod damping of the movement of the curtain can be achieved.
  • the damping element comprises a stop of elastic material, so that the end stop is designed to be particularly resilient, in order to reduce the noise during rapid pulling up of the curtain.
  • the Notraff beautifier comprises a tensioned guide rope, along which the curtain is movable.
  • the curtain can be guided on the one hand in the movement of the guide rope and on the other hand, the guide rope can also be part of the Notraff issued at the same time.
  • the guide cable can be coupled with a pulley, which includes a movable and biased shaft.
  • the movable shaft may be mounted on a carriage, which is held movable in a housing. This can be obtained on the pulley the desired translation for the movement of the guide rope and the curtain.
  • the movable shaft of the pulley can be pretensioned by means of a tension spring, preferably a helical spring. This avoids the problems of reducing pressure within a gas spring.
  • a linear damper in a further embodiment of the invention is coupled as a damping element, a linear damper with the movable shaft.
  • the pulley block can be braked via the damping element.
  • the pulley can be a fixed and a movable Include shaft around which the pull rope is deflected at least twice, preferably four times, depending on the travel and transmission ratio.
  • a deflection roller for guiding the traction cable.
  • a sunshade system comprises a movable curtain 3, which is formed from individual fins 15, which are held on a ladder cord 2.
  • a guide cable 1 is laterally provided, which is stretched over the entire length of the curtain 3.
  • a rail 18 is provided at the bottom of the curtain 3, on which the individual slats 15 of the curtain 3 can be stored when pulling up.
  • the guide cable 1 passes through the slats 15 and the rail 18 and is fixed to the bottom side of a trigger mechanism 4, which is not shown in detail. In the normal operating situation, the guide cable 1 remains stretched between this triggering mechanism and a emergency catcher 5. On the trigger mechanism 4, however, means are provided for releasing a lock, so that then the guide rope 1 can be pulled through the emergency lifting device 5, for example, when a building opening adjacent to the curtain 3 due to an emergency must be released. Then the guide cable 1 pulls over a driver, the rail 18 upwards until the curtain 3 releases the corresponding building opening.
  • a head profile 17 is still provided, may be provided in the drive means for the raising and lowering of the curtain 3. Adjacent to the profile 17 is mounted a Notraff driving 5, wherein the guide member 1 is guided via a guide roller 12 to the Notraff issued 5.
  • FIG. 2 the emergency lifting device 5 is shown in detail.
  • the emergency lifting device 5 comprises a pulley 6, which has a movable shaft 7 arranged in a housing 22 and a stationary shaft 8. On the shaft 7 a plurality of pulleys 25 are rotatably mounted, while on the shaft 8 also pulleys 24 are rotatably mounted. As a result, the guide cable 1 between the pulleys 24 and 25 are wrapped so many times until the desired gear ratio is reached.
  • the movable shaft 7 is mounted on a carriage 20, which includes lateral sliding elements 21 which are supported on the housing 22.
  • the carriage 20 is biased by one or more tension springs 10.
  • a damping element 9 in the form of a linear damper is fixed to the carriage 20, which comprises a movable piston rod 19.
  • the Notraff worn 5 is constructed in mirror image, that is, there is a movable shaft 7 and a fixed shaft 8 is designed as a pulley 6 for each guide rope 1, wherein the tension springs 10 and the damping elements 9 are fixed in a central region of the emergency lifting device 5.
  • the tension springs 10 act on the carriage 20, so that the movable shaft 7 is moved to the center of the emergency latching device 5.
  • the guide cable 1 is retracted with a corresponding translation by the pulley 6, so that the curtain 3 is quickly retracted at high speed.
  • the damping element 9 can be adjusted so that a damping effect only after a predetermined travel, for example, from half of the retraction of the curtain 3 is effective. This ensures that the curtain 3 is first raised relatively quickly and only before a final position takes place a deceleration by the damping element 9.
  • a projection 23 is further formed, which serves as an end stop for the sliding element 21. This end stop 23 predetermines the end position of the curtain 3 when the emergency lifting device 5 is triggered.
  • a cushioning 13 is arranged, which comprises an elastic material and thus damps a shock movement of the carriage 20 within the housing 22.
  • FIG. 3 is the Notraff issued 5 shown in the retracted end position, in which the sliding member 21 abuts the end stop 23.
  • the guide member 1 is stored by the multiple wrapping by the rollers 24 and 25 to the shafts 7 and 8 in the emergency handling device 5, so that the curtain 3 is in a raised position.
  • the Notraff recognized 5 can be moved back into the cocked position, in which case only the guide cable 1 must be fixed to the trigger mechanism 4 again. In this respect, a multiple examination of the emergency lifting device 5 can be carried out without problems.
  • the curtain 3 is formed of a plurality of individual slats 15.
  • the slats 15 it is also possible, instead of the slats 15, to provide a textile drapery, roller blinds, external blinds, etc.
  • the curtain 3 can be moved both manually and by motor during normal operation.
  • the Notraff worn 5 is arranged horizontally adjacent to the profile 17 of the sun protection system. This results a particularly compact structure that is relatively flat. It is of course also possible to arrange the emergency lifting device 5 above the profile 17.
