Definitions

  • the invention is based on the DF-U-8524022 and relates to a sun and / or weather protection roof with a fabric that can be wound onto and / or unwound from a tubular fabric shaft and the front edge of which is not held on the fabric shaft at one side Guide rail sliding failure profile is attached, on which the cloth constantly attack exciting and pulling pulling members pulling, which can be actuated via a drive shaft extending through the cloth shaft.
  • the forces exerted by the clutch spring are usually not sufficient to prevent the extended cover from sagging due to its own weight, which not only affects the visual impression of the roofing, but also rain and / or condensation water collects in the cover recesses. the weight of the brackets of the canopy significantly.
  • the cloth troughs can still be on the glass roof winter garden, which means that the cloth is considerably impaired in appearance by wiping the dirt off the roof and is damaged by chafing marks.
  • the tension forces of the clutch spring are also too low to prevent the fluttering and beating of the cloth in windy weather with the negative consequences both on the cloth itself and on the holder of the roof.
  • the object of the invention is to provide a roof of the type described above so that the run of the cloth unwound from the cloth shaft is always kept taut, without thereby excessively stressing the cloth in the long run.
  • the cloth is pulled off a cloth shaft, which is rotated against the resistance of one of the second braking devices, since the coupling on which this braking device is mounted locks in this direction of rotation.
  • the pulling elements engaging on the drop profile and pulling out the cloth are positively connected to the drive shaft and are expediently designed as revolving toothed chains which run over sprockets or sprocket gears attached to the drive shaft.
  • the drive shaft itself is freely rotatable through the cloth shaft in the unwinding direction of the cloth, since the first clutch mounted on the drive shaft does not lock in this direction of rotation.
  • the cloth is removed from the cloth shaft by these measures according to the invention handled with a force whose constant size over the entire extension process can be adjusted via the second braking device so that the extended cloth does not sag.
  • the drive shaft is turned in the opposite direction.
  • the first clutch locks, so that the cloth shaft is rotated in the winding direction via the associated first braking device.
  • the traction elements are returned at a speed which is lower than the circumferential speed of the fabric shaft, with a length compensation between the circumference of the fabric winding and the traversed distance of the traction elements being obtained at the same time via the first braking device.
  • the cloth is then wound up under tension.
  • This voltage which is less than the pull-off voltage of the Cloth is set with the first braking device, which transmits the forces from the drive to the cloth shaft.
  • each braking device can have a coupling which locks in one direction of rotation and which is expediently used as a clamping or Freewheel clutch is formed, have mounted brake disc, act on the preloaded brake elements.
  • These brake elements can preferably be designed as ring disks lying laterally on the brake disk or belts wrapping around the brake disk.
  • fabric support rollers which slide together with the drop profile in the guide rails, are moved out at intervals between the fabric when the fabric is extended the drop profile and the fabric shaft.
  • the pergola shown has two lateral running or guide rails 1, on which a tubular fabric shaft 2 is held and in which a drop profile 4 slides, which is attached to the free edge of an awning fabric 3 that can be wound onto the fabric shaft 2.
  • Tension elements 5 designed as toothed chains act on the drop profile 4 and hold the strand of the fabric 3 pulled off from the fabric shaft 2 under tension.
  • the toothed chains 5 are held by deflection wheels 6 held at the end of the guide rails 1 opposite the cloth shaft 2 deflected and driven by sprockets 7 and 8, which are positively connected via a gear transmission 12, 36 to a drive shaft 9.
  • the drive shaft 9 extends through the cloth shaft 2 and carries an electric motor 10 designed as a tubular motor, which is attached to a bearing plate 11 in a rotationally fixed manner.
  • the cloth shaft 2 On the bearing plate 11, which is non-rotatably held in one of the guide rails 1, the cloth shaft 2 is rotatably supported at one end.
  • the end of the drive shaft 9 opposite the electric motor 10 protrudes from the cloth shaft 2, is rotatably supported in the other guide rail 1 and carries a drive gearwheel 12, the pitch circle diameter of which is smaller than the outer diameter of the cloth shaft 2.
  • the drive gear 12 is part of a 1: 1 transmission, the output gear 36 is arranged on a shaft 37, on the ends of the sprockets 7 and 8 are attached.
  • the drive shaft 9 is guided through a sleeve 13 which is formed on a flange 14 which is prevented from rotating by a threaded pin 15 protruding from the adjacent guide rail 1.
  • an end plate 16 is firmly inserted, in which in the vicinity of the wall of the cloth shaft 2 are screwed a plurality of threaded rods 17 forming a cage.
  • an intermediate washer 19 is provided, which can be fixed with nuts 18 and divides the cage into two zones.
  • the first zone of the cage is between the intermediate washer 19 and free end of the threaded rods 18 mounted on the drive shaft 9 with a first one-way clutch 20, the brake disc 21 of a first braking device.
  • the second zone of the cage has a second brake disk 23 rotatably arranged on the sleeve 13 with a second one-way clutch 22, which locks in the direction opposite to the first one-way clutch 20.
  • Brake elements 24 and 26 are pressed against each of these brake disks 21 and 23 by springs 25 and 27, respectively, which are supported on the intermediate ring disk 19. While the abutment to the intermediate ring disc 19 for the spring 27 is the end plate 16, this abutment for the spring 25 is formed by an end plate 28 which is held on the free end of the threaded rods 17 with nuts. By changing the distance between The intermediate ring disk 19 and the end plate 16 or end plate 28 can be used to set the force with which the springs 25 and 27 press the brake elements 24 and 26 against the brake disks 21 and 23, respectively.
  • the drop profile 4 is moved into the drop position with the pulling elements 5 actuated by the electric motor 10 via the drive shaft 9, the drive gear 12 and driven gear 36 and the chain wheels 7 and 8.
  • the cloth 3 is pulled off from the cloth shaft 2 rotating after overcoming the resistance of the second braking device 23, 26, 27 with constant tension.
  • the electric motor 10 is reversed.
  • the rotating drive shaft 9 locks the first one-way clutch 20, as a result of which the first brake disk 21 is rotated and the cloth shaft 2 is non-positively driven via the first brake elements 24 and the end plate 16.
  • the failure profile 4 is returned to the rest position by the traction elements 5.
  • the path covered by the drop profile 4 is, due to the dimensioning of the drive gear 12 and the fabric shaft diameter, less than the covered circumferential distance of the fabric roll, so that a tension builds up in the run of the fabric 3 between the extension profile 4 and fabric shaft 2; because only the length is wound up on the cloth 3, which corresponds to the distance traveled by the traction elements 5, since the difference between the circumference of the rotating cloth roll and the distance covered by the returned failure profile 4 is compensated for with the first brake unit 21, 24, 25.
  • cloth support rollers 30 (FIG. 3) also slide, which are arranged in the case of large roofs between the drop profile 4 and the cloth shaft 2 at a distance below the stretched strand of the cloth 3 in order to reliably prevent its sagging.
  • These cloth support rollers 30 are provided with axial pins 32 on which pawls 32 are pivotally mounted. These pins 31 protrude laterally beyond the pawls 32, which, with recesses 38, grip the corresponding pin 31 on the fabric support roller 30 preceding in the direction of failure or on the profile 4 and thereby the support rollers 30 from the rest position below the fabric shaft 2 into the Pull the support position.
  • the support position is determined by pins 33, which are provided at different heights on the guide rails 1 on their sides facing the cloth 3 and engage under a guide edge 34 of the pawls 32.
  • the pawls 32 are raised and their recess 38 comes out of engagement with the pin 31 of the preceding cloth support roller 30 or the drop profile 4, so that no more tensile forces act on the respective cloth support roller 30.
  • the pin 31 of the preceding cloth support roller 30 or the drop profile 4 comes to rest on an edge of the recess 38 in the pawl 32 and displaces the cloth support roller 30 in the direction of the rest position.
  • the pawls 32 lose the support from the pins 33 and, with the cutouts 38, again engage the pins 31 on the adjacent one Cloth support roller 30 or on the drop profile 4, as a result of which the cloth support rollers 30 and the drop profile 4 are put together again to form a bandage which is released when the cloth is extended.
