Definitions

  • the invention relates to a curtain element, in particular a roller shutter, but also, for. B. a vertical awning, awning or blackout system, with a housing and a Wiclelwelle mounted therein, which can be driven by a torque-transmitting gear connected to it, which is frictionally and circumferentially adjustable on the housing and separated by a partition from the rolled-up room is.
  • Such a roller shutter is described in DE-GM 84 11 831, the generally customary partition, which has the function of separating the gear compartment from the armored compartment and retaining laterally displaceable roller shutter bars in the armored compartment, is not shown.
  • the winding shaft and the gearbox are mounted on the end wall of the housing.
  • it is provided with a flange which is gripped radially from the outside inwards by three clamping claws distributed over the circumference and screwed onto the end wall of the housing.
  • three pins are formed on the end wall, each of which extends through an arcuate elongated hole in the gear flange.
  • the gearbox can only be rotated through a relatively small angle while overcoming the friction of the claws, when mounting the finished roller shutter on the building, the position of the drive shaft should be adjusted depending on the installation situation.
  • the invention is therefore primarily based on the object of a curtain element of the type mentioned create, which allows any rotation of the braked gear in any desired position during assembly.
  • a support sleeve which rotatably supports the winding shaft and holds the transmission in a rotationally fixed manner in a bore in the partition wall and can be clamped to the partition wall by clamping members with a frictional force to be overcome by a specific torque.
  • the proposed arrangement of the clamping members on the partition wall has the advantage that, in contrast to the arrangement on the housing end wall, there is the possibility of clamping the wall between two disk-shaped clamping members connected to the transmission in a rotationally fixed manner, while the radial forces are absorbed by the bore in the partition wall become.
  • the disk-shaped clamping members lie evenly rubbing over the entire circumference on the area of the partition wall surrounding the bore, without additional measures being required, as in the case of clamping claws, to prevent an incorrect position. Since the clamping force is distributed over a large area and, in addition, disk-shaped clamping members can be pressed against the partition wall from both sides, the necessary friction can be achieved with a relatively low surface pressure. As a result, the clamping can be adjusted easily and precisely, and the clamping members can be made of a suitable plastic, e.g. B. polyamide.
  • the main advantage of the invention is, however, that the desired rotation of the gearbox, while overcoming the friction caused by the clamping, is no longer limited by elongated holes or other stops.
  • the clamping members can absorb the torque exerted by the weight of the tank on the transmission, so that in this respect the same effect results as with a screwed transmission.
  • the torque exerted by the clamping members is preferably approximately twice the torque generated by the weight of the curtain.
  • the storage and clamping of the gearbox on the partition has the further advantage that the much more expensive end wall can have a very simple shape - which is particularly important for a program with a large number of housing cross sections - and there is no need in connection with the storage and Clamping the gearbox on the end wall provide threaded holes, pins or the like, which must be milled off in a different roller shutter when using the same end wall. No externally visible screws need to be used.
  • the housing does not need to be opened to adjust the angular position of the gearbox during assembly if there is a vertical slot in the rear wall of the housing in the transverse plane, in which the drive shaft later extends, through which a tool, for example a Screwdriver can be inserted into the housing and inserted into the mounting hole for the drive shaft of the gearbox, in order to then turn the gearbox by swiveling the tool.
  • a tool for example a Screwdriver can be inserted into the housing and inserted into the mounting hole for the drive shaft of the gearbox, in order to then turn the gearbox by swiveling the tool.
  • the clamping members are formed by a flange formed on the carrying sleeve and a clamping disk, between which the partition can be clamped axially.
  • the clamping disc is preferred can be tensioned by means of screws arranged within the hole in the partition and engaging in the carrying sleeve.
  • roller shutters in which the gear is in the operating state within the housing.
  • the drive shaft and thus also the gear unit are arranged in the wall next to the housing.
  • the output shaft of the gearbox remains in a torque-transmitting connection with the winding shaft.
  • the known roller shutters with an external gear were different from the roller shutters with an internal gear because of the axial displaceability with regard to the mounting of the gear and the winding shaft. Even this variety of types was a disadvantage because of the higher manufacturing costs.
  • Another major deficiency of the known roller shutters with an external gear is that the shutter armor must be held against unwinding during the entire assembly because the unbraked gear can rotate freely.
  • the carrying sleeve with one or more eccentrically arranged, axially extending projections detachably engages in bores or recesses of the gear.
  • front-mounted roller shutters with internal and external gear only need to differ in that in the latter the end wall is provided with a hole for pushing out the gear. Even the end wall can be identical if you provide it with an optionally removable cover that closes the hole.
  • the invention When used as roller shutters with an external gear, the invention has the further significant advantage that the gear and thus the roller shutter curtain are held by the clamping members during assembly work, as long as the gear is still in the housing and the axial projections on the carrying sleeve are in engagement with the transmission. Only in the short phase of assembly between pushing the gearbox out of the housing and inserting the drive shaft into the gearbox does the armor have to be held against unwinding.
  • the roller shutter shown in the drawing has a housing 10 known per se with a rear wall 12, a ceiling 14, a revision flap 16 and end walls 18.
  • the housing parts are hooked, screwed and / or locked together in a known manner.
  • a tubular winding shaft 20 is rotatably mounted, on which a roller shutter armor 22 forming a curtain can be wound. This is guided outside the housing 10 in guide rails 24, which are connected to the housing 10 during assembly of the roller shutter and fastened to a window frame 26, so that in the assembled state the housing 10 is fastened to the building via the guide rails 24.
  • a shaft core 28 is inserted into each of its ends and screwed by means of one or more screws 30.
  • the shaft cores 28 each form axiai projecting journal 32 with a cylindrical outer peripheral surface. While the winding shaft 20 can be supported in any conventional manner at the end opposite the drive, the pin 32 is rotatably received in the matching bore of a support sleeve 34 on the drive-side end, which in turn is fastened to a partition 36 of the housing 10 is.
  • the latter is e.g. B. hooked on its upper edge at 38 with projections on the end wall and screwed to the lower edge by means of screws 40.
  • the carrying sleeve 34 consists of polyamide, sits with an outer cylindrical bearing surface 42 in a suitable bore in the partition wall 36 and lies with a flange 44 on the outer side of the partition wall 36 facing away from the roller shutter curtain.
  • On the inner side of the partition 36 is in the exemplary embodiment also made of polyamide clamping disc 46, which sits on a hub-shaped part of the carrying sleeve 34 and is tightened axially by means of six screws 48, which engage in the hub-shaped part of the carrying sleeve 34, the metallic partition 36 is clamped between the flange 44 of the support sleeve 34 and the clamping plate 46.
  • the axial clamping force can be determined by the material elasticity of the clamping disc 46 and the extent of its deformation in the state screwed against the carrying sleeve 34.
  • the friction generated by the clamping force between the partition 36 on the one hand and the carrying sleeve 34 and clamping disc 46 on the other hand should be so large that the torque exerted on the winding shaft by the weight of the roller shutter curtain is held braked, but a rotation during assembly by a manually applied torque the carrying sleeve 34 is possible relative to the partition 36.
  • the roller shutter is driven by means of a hand crank 50 via a commercially available universal joint plate 52 fastened to the inside of the window frame 26 in the embodiment according to FIGS. 1 to 6 and one of the latter through a bore 53 in the window frame 26 to a gear 54 in the housing 10 extending drive shaft 56.
  • the gear 54 is arranged in the housing space between the partition wall 26 and the adjacent end wall 18.
  • the output shaft 58 of the gear 54 has a hexagonal cross section and sits coaxially in a central opening with a suitable cross section of the shaft core 28. There is therefore a torque-transmitting connection between the output shaft 58 of the gear 54 and the winding shaft 20.
  • the gear itself is, for. B. a known worm gear and therefore need not be shown in detail.
  • the pins 60 are stepped and have a cylindrical cross section in the outer or front part and a hexagonal cross section in the rear part (see FIG. 3).
  • the receiving holes in the gear 54 are also shaped accordingly.
  • the front-mounted roller shutter When delivered, the front-mounted roller shutter is completely assembled except for the drive shaft 56 and the guide rails 24. In this state, no special measures are required to prevent the armor from rolling off the winding shaft 20, because this is held in a rotationally fixed manner by the clamping of the support sleeve 24 on the partition wall 36.
  • the fitter must first consider where the universal joint plate 52 is attached and under what inclination to the horizontal the bore 53 is to be drilled through the window frame in order to remove the drive shaft 56 from the universal joint plate 52 to lead to gear 54.
  • Fig. 3 shows z. B. an installation situation in which the drive shaft 56 extends horizontally.
  • gear 54 must be set obliquely so that the polygonal in cross section, z. B. square or hexagonal drive shaft 56 in alignment with the hole in the window frame in the intended, cross-sectional receiving bore in the gear 54 can be inserted.
  • the clamping between the parts 34, 36 and 46 continues to hold the winding shaft 20 and the gear 54 in the set position, so that it is not difficult to subsequently move the housing 10 over in a known manner to fasten the guide rails 24 to the window frame 26, to insert the drive shaft 56 through the hole in the window frame 26 and the slot 64 in the housing 10 into the transmission and then on the inside of the window frame to connect the drive shaft 56 to the hand crank 50 via the universal joint plate.
  • the described mounting and braking of the gear 54 can advantageously also be used for roller shutters with an external gear according to FIGS. 7 and 8.
  • Such a roller shutter differs in the embodiment according to the invention from a roller shutter with an internal gear according to FIGS. 1 to 6 in the delivery state only in that instead of the closed end wall 18 an end wall 66 with an opening 68 so large is used that the gear 54 according to FIG Attachment of the housing 10 to the window can be pushed laterally out of the housing into a cavity 70 in the building wall 72.
  • a normally horizontal bore 74 is drilled through the masonry of the wall that opens into cavity 70.
  • the universal joint plate 42 is attached to the inside of the wall 72 in front of the bore 74.
  • a collar shown in FIG. 8 is located on the end wall 68, by means of which the collar rests on the adjacent housing parts , after removing the inspection cover 16 exposed hole 76 through which one can engage the gear 54 with a screwdriver or other tool shaft.
  • the output shaft 58 which is polygonal in cross section, slides within its receptacle bore of suitable cross section in the shaft core 28, but remains non-rotatably engaged with it.
  • the gear 54 is overhung via its output shaft located in the shaft core 28. 8, it is held axially by the drive shaft 56 against rotation and by a locking screw 78 screwed radially through the shaft core 28 against the output shaft 58.
  • the invention is suitable for any cross-section of the roller shutter housing.
  • the individual parts mentioned above can also have a shape other than that described and shown and can consist of a different material, provided that essentially the same function is achieved.
