Definitions

  • the present invention relates to a sun protection device, in particular for facades, with an upper housing, on which an upper first curtain is held, which is movable via drawstrings between a retracted position and a surface covering position.
  • Sun protection devices for facades are known, which are mounted in the upper area of a façade field and, if necessary, lower a blind made of slats by means of a motorized or manual drive. This makes it possible to reduce the sunlight to the desired level.
  • a motorized or manual drive This makes it possible to reduce the sunlight to the desired level.
  • the sun protection device has both an upper first curtain and a lower second curtain which can be moved and fixed independently of one another within a hanging surface.
  • the hanging surface can be darkened individually according to the wishes of the user, with a blind can be provided by the lower curtain.
  • the Sun protection device can thus take over several functions and allows great flexibility.
  • the lower curtain is held on at least one prestressed guide belt.
  • the curtain In order to move the lower curtain upwards and fix it in any position, the curtain must be held against gravity, for which purpose at least one pretensioned guide strip is provided, which can be fixed in different positions.
  • the holding mechanism for fixing the guide band and the lower curtain can be effected by friction or clamping forces, which can act both in the upper region and in the lower region.
  • the upper curtain along the at least one guide belt is movable, so that the guide belt takes on both the function of the tensioning of the lower curtain as well as that of the leadership of the upper curtain.
  • a tensioning device is provided above the upper curtain, by means of which the at least one guide band is retractable.
  • the clamping device can be accommodated substantially horizontally within the upper housing.
  • a guide band can be provided on both sides of the hanging surface in each case, which are connected to one another via a fixed to the lower curtain bar.
  • the guide tape can be guided in slots or openings of the upper curtain.
  • a prestressed pulley can be provided, by means of which the guide belts are retractable. It can be provided for each lateral guide belt pulley, which has a translation and four, six or wisheschen may be formed.
  • the lower curtain is preferably formed as a windable awning, which may consist of a textile material in order to achieve a desired privacy.
  • the awning can be wound around a prestressed roll that opposes the force of a clamping device acts.
  • a holding mechanism may be provided on the awning, which is formed for example by a stationary motor (drive).
  • Both the upper curtain and the lower curtain can be driven by a motor, so that an automatic control of the upper and lower curtain is possible.
  • the bottom of the upper curtain and the top of the lower curtain stop surfaces for the adjacent curtain form the bottom of the upper curtain and the top of the lower curtain stop surfaces for the adjacent curtain, so that the maximum overlap of the hanging surface depends on the position of the adjacent curtain.
  • a sun protection device 1 which has an upper curtain 3, which is formed from individual slats, which are held together by two laterally arranged guide bands 5.
  • the upper curtain 3 can be withdrawn from a Position are moved by gravity in an extended position, for which purpose a manual or motor drive is provided in a housing 9, by means of which the guide belts 2 can be retracted.
  • a lowermost slat 4 or an end strip is pulled over the guide belts 2 upwards and adjusted to the desired position.
  • the fins 3 may be made of plastic or metal and coated as needed with a reflective or absorbent coating.
  • the lamellae 3 are guided laterally on guide belts 5, the louvers 3 having slots or openings in which the lateral guide belts 5 are accommodated.
  • a clamping device 6 is further provided, which is connected to the guide belts 5.
  • the guide bands 5 are connected at their lower end to a strip 31 on which a lower curtain 30 is mounted.
  • the curtain 30 is used as an awning e.g. formed of textile material which can be wound on a roll 32 which is accommodated in a housing 7.
  • the roller 32 may be manually or motor driven and is connected to a holding mechanism to fix the lower curtain 30 in the desired position. For example, a motor can apply the necessary holding forces. At rest, the bar 31 is pulled with the lower curtain 30 on the tensioning device 6 upwards, wherein the guide belts 5 are biased on the tensioning device 6.
  • the guide belts 5 are guided in the upper region in each case around a deflection roller 8, so that the tensioning device 6 is arranged substantially horizontally in the housing 9.
  • the force of the tensioning device 6 is greater than the weight of the lower curtain 30, but smaller than the holding forces by the holding mechanism on the roller 32nd
  • FIG 3 an embodiment of a clamping device 6 is shown in detail.
  • the guide strip 5 is guided around the deflection roller 8, which is held on a fixed bearing 13.
  • the guide band 5 is deflected by a pulley, which is formed from a first guide roller 10 and two further guide rollers 11 and 12.
  • the guide roller 12 is held on the fixed bearing 13 and the end of the guide strip 5 is fixed at a position 16.
  • the rollers 10 and 11 are held together by a rod 15, wherein a spring 14 between the rod 15 and the fixed bearing 13 is provided.
  • the spring 14 may be formed as a helical spring or gas spring. Instead of the four-pulley block shown, other ratios can be selected, for example by a six- or eight-strand pulley.
  • a modified clamping device 6 is shown, which largely corresponds to the clamping device of Figure 3.
  • the tensioning device 6 comprises a pulley with pulleys 10, 11, 8 and 12, wherein the pulleys 10 and 11 relative to the pulleys 8 and 12 are movable.
  • a central spring 17 is provided, which is tension loaded and engages on opposite sides of the rod 15 to move the pulleys to each other when notching the guide bands.
  • FIGS. 5A and 5B a modified tensioning device 6 is shown in which a four-pulley block pulley is likewise used, two adjacent rollers 8 and 18 being mounted on the fixed bearing 13, while two further rollers 10 and 19 are mounted on a bracket 20.
  • the bracket 20 may then be biased in a direction away from the rollers 8 and 18 to retract the drawstring 5 as needed.
  • a tensioning device in which a continuous guide belt 5 is biased by a pulley.
  • the guide band 5 is connected at opposite ends in each case with the rod 31 and then guided above the curtain on a pulley, which is formed from eight rollers, four rollers 8 are mounted on a fixed bearing 13, while four rollers 21 mounted on a bracket 22 are.
  • the guide band 5 is then guided in accordance with the rollers 8 and the rollers 21, so that when moving the bracket 22 away from the fixed bearing 13, the tension band 5 is retracted.
  • FIG. 7 shows a tensioning device in which the guide belt 5 can be wound around a respective drum 23, which are pretensioned via a central torsion or spiral spring 24.
  • the drawstrings 5 are in turn fixed to a rod adjacent to a schematically indicated housing 7.
  • each drum 23 may be biased to a fixed bearing 13 via suitable means to wind the drawstring 5 if necessary can.
  • the sun protection device 1 is shown in several positions. In the left position of the upper curtain 3 and the lower curtain 30 is arranged approximately centrally above the hanging surface. In the adjacent sun protection device, the upper curtain 3 is raised slightly, so that only a glare protection is provided, but in the remaining light is let in.
  • corresponding slots must be arranged on the guide strips 5 in the region of the fins 3, through which holding means for the lower curtain 30 are then carried out. If no overlapping handling is desired, a lowermost sipe or a corresponding strip 4 can serve as a stop for the lower curtain 30.
  • the upper curtain 3 is formed from fins, while the lower curtain is formed as awning 30. It is natural It is also possible to make both curtains from slats or awnings. Other hangings, such as Roman blinds, etc. can be used.
  • U-shaped housing 7 and 9 are provided in the embodiments shown, which are formed substantially closed. It is of course possible to provide instead of the housing and an open bar, which provides only the necessary attachment to the facade field.
  • one or more guide belts 5 can also be arranged, for example when the hangings 33 extend over a greater width.
