Definitions

  • the drive of the winding shaft, on which the roller shutter of a roller shutter is wound, is carried out with a belt, wherein the unneeded part of the roller shutter belt is wound on a belt pulley.
  • the belt pulley is spring-loaded.
  • a drive according to the preamble of claim 1 is e.g. from EP 0 860 579 A.
  • the friction drive has three friction rollers, which are positively coupled with each other via spur gears.
  • the belt winds through between the friction rollers, the friction rollers being arranged so that a sufficient wrap angle is achieved.
  • the retrofitted drive system may not protrude appreciably in width over the belt. Otherwise, it does not find sufficient acceptance because a bulky drive system is perceived as extremely disturbing.
  • the new drive device has two boards, between which the gears are mounted, which form the reduction gear.
  • the input gear is composed of a worm gear and a spur gear coupled to it rotatably.
  • an intermediate gear is driven, which consists of a spur gear and a pinion.
  • the pinion is adjacent to the other board, so that between the Spur gear and the pinion of the intermediate gear, there is a distance corresponding to the width of the driven roller shutter belt.
  • the output gear is driven, which is rotatably connected to a friction roller for the roller shutter belt.
  • the width of the teeth of the individual spur gears depends on the torque to be transmitted. The largest tooth width is required in the region of the output gear, so that this ultimately determines the lateral projection over the width of the friction roller.
  • the width of the friction roller depends on the width of the roller shutter belt. Due to the spatial separation of the pinion and the spur gear at the intermediate gear is ensured that the lateral housing projection, which is enforced by the gears, on both sides of the roller shutter is about the same size. As a result, a symmetrical course of the roller shutter belt is achieved by the drive system, based on the transverse extent.
  • the new drive system can be used with small width both right and left of the window in the window reveal.
  • the construction becomes very cost-effective in terms of production, when the two boards are integrally connected to one another via a flange which extends along one edge of the boards.
  • the transmission housing formed by the boards gets a C-shaped profile, wherein the flange is the back, while the board are the lateral legs.
  • the flange has a tab or an extension which projects between the boards and serves as a mounting surface for the motor.
  • This tab or extension may be unlatched from a central area such that the boards extend on both sides of and beyond the motor. This results in a substantial stiffening.
  • the idler gear is expediently located on the load side of the friction roller.
  • the entrainment effect of the roller shutter belt can be improved if a second friction roller is provided, which is driven in a form-fitting manner.
  • a further deflection roller can be arranged between the boards, which is positioned so that it holds open a brake of the present Gurtwicklers.
  • An existing control electronics is expediently arranged in extension of the drive motor on the side which is remote from the screw. This places the control electronics in an area that does not force the width of the array to increase.
  • FIG. 1 shows a window reveal 1, in which a window frame 2 is attached.
  • a sash 4 is hinged by means of two hinges 3, in which a window pane 5 is inserted.
  • a roller shutter On the outside of the window frame 2 is a not visible in the figure roller shutter, which is on a on the Outside, not shown winding shaft is wound up.
  • a roller shutter belt 5 is provided which leads through an opening 6 in the window frame 2 of the belt pulley of the winding shaft inwards.
  • the roller shutter belt 5 passes through a drive device 7 and is wound on a Gurtwickler 8.
  • the Gurtwickler 8 sits on the inside of the window frame 2 and includes a rotatably mounted belt pulley, which is biased in the winding direction of the roller shutter belt 5 by a coil spring.
  • the drive device 7 can be programmed.
  • the control buttons 9 are seated in a housing shell 11, which covers the interior of the drive device 7.
  • the drive device 7 is pivotally mounted on the inside 2 about a vertical axis by means of angles 12 which are screwed to the inside of the window frame 2.
  • FIGS. 2 and 3 The internal structure of the drive device is shown in FIGS. 2 and 3.
  • a fastening tab 16 is disengaged from the flange 15.
  • the fastening tab 16 protrudes between the two boards 13 and 14 and extends at right angles to the flat back flange 15.
  • At the top and at the bottom of the flange 15 is in two other attachable tabs 17 and 18, which are parallel to each other.
  • the push-on tabs 17 and 18 serve as guide tabs for holding the Housing shell 11, which contains corresponding guide grooves.
  • the gear train of a transmission 19 is included between the fastening tab 16 and the lower peg 18, the gear train of a transmission 19 is included.
  • the drive is done by means of a permanent-magnet electric motor 21, which is fastened with its front side 22 on the mounting strap 16 upstanding and projects with its armature shaft 23 through a corresponding hole in the tab 16 down in the direction of the clip 18.
  • On the armature shaft 23 is seated non-rotatably a worm 24th
  • the distance between the boards 13, 14 is otherwise dimensioned so that between them the motor 21 just fits.
  • an input gear 25 is driven, which is arranged between the worm 24 and the flange 15.
  • the input gear 25 is rotatably mounted on an axis 26 which passes through aligned holes in the boards 13 and 14 and is axially secured in this by suitable means.
  • the input gear 25 is composed of a worm wheel 27 and a pinion 28 which are rotatably connected to each other.
  • the pinion 28 is located, as Figure 2 reveals, in the immediate vicinity of the left seen from the front board 14, while the screw 24 is located centrally between the two boards 13 and 14 under the screw 24.
  • the input gear 25 drives an intermediate gear 29, which is also mounted so as to be loosely rotatable on an axle 31.
  • the axis 31 passes through corresponding holes in the two boards 13 and 14th
  • the intermediate gear 29 consists of a spur gear 32 and a pinion 33.
  • the spur gear 32 rotates immediately adjacent to the left board 14 and meshes with the pinion 28, while the pinion 33 of the opposing right board 13 is immediately adjacent.
  • the two gears are rotatably connected to each other via a tube 34.
  • the pinion 33 finally drives a meshing with him output gear 35, the rotation, for example, is integrally connected to a friction roller 36.
  • the friction roller 36 is rotatably mounted together with the output gear 35 on a further axis 37 which removably inserted into bores of the two boards 13 and 14.
  • Another output gear 38 meshes with the output gear 35 and serves to drive a further friction roller 39, which is illustrated by dashed lines in Figure 3.
  • this friction roller 39 is taken out so as not to obscure the view from the front of the underlying gears.
  • the output gear 38 is also rotatably mounted on a loose insertable axle 39.
  • the two friction rollers 39 and 36 are identical with each other, together with the two gears 35 and 38. Since the output gear 38 meshes with the output gear 35, it is also located next to the board 13.
  • FIG 3 To a lateral emigration of the belt 5, the in FIG 3 is shown by a dashed line, to avoid carrying the friction roller 36 at a distance from the output gear 35, a flanged wheel 41, the outside of the spur gear 32 is adjacent.
  • the occurring torque increases, that is, the largest torque occurs at the output gear 35.
  • the width of the teeth of the spur gear 35 must be matched to this torque.
  • the torque in the region of the spur gear 32 of the intermediate gear 29, however, is smaller, so that the tooth width may be smaller. Due to this design limitation, it follows that the left-facing side of the spur gear 35 of the board 13 has approximately the same distance as the right-facing side of the flange 41, that is, the thickness of the flange 41 together with the thickness of Spur gear 32 corresponds approximately to the thickness of the output gear 35.
  • the running surface of the friction roller 36 extends between the flanged wheel 41 and the output gear 35 centrally between the two boards 13 and 14, so that the continuous roller shutter belt 5 centrally through the drive means 7 passes from top to bottom.
  • a idle roller 42 is provided, which is shown only in FIG.
  • the idle roller 42 is removed from the illustration of Figure 2 in order not to obscure the view of the screw located behind it 24 and the intermediate wheel 29.
  • the idle roller 42 is loosely rotatable on an axis 43 mounted between the boards 13, 14. It serves as a pulse generator in conjunction with electronic donors, not shown further, such as field plates, Hall probes, photodiodes and the like. These pulses are fed to an electronic circuit 43, which is located above the drive motor 21 between the two boards 13 and 14.
  • both boards are extended at the lower end via mutually parallel tabs 44 and 45, between which a guide roller 46 is rotatably mounted on an axle 47.
  • the roller 46 is located under the front friction roller 39 and thus at a distance from the flange 15th
  • roller shutter belt 5 The course of the roller shutter belt 5 is as follows:
  • roller shutter belt 5 leads to the free end of the retaining tab 17 over to the idler 42. It lies on the user-facing side on the outer peripheral surface of the idle roller 42 and leads from there in the direction of the flange 15 to the rear friction roller 36th
  • the roller shutter belt 5 runs through the gap between the tube 34 and the friction roller 36 therethrough.
  • the roller shutter belt 5 runs from here around the circumference of the friction roller 36 around in the gap between the friction roller 36 and the web 15 and the clip 18.
  • the roller shutter 5 of the friction roller 36 Approximately at the height of the axis 37, the roller shutter 5 of the friction roller 36 and leads to the user, that is from the window frame 2 away to the front friction roller 39.
  • Gurtwicklers 8 On the user-facing side of the friction roller 36 of the roller shutter 5 leads lying on in the direction of the guide roller 46 and from there into a corresponding slot 48, Gurtwicklers 8.
  • the drive device 7 is fastened to the window frame 2 with the aid of the mounting brackets 12.
  • the flange 15 facing the window frame 2.
  • the two attachment tabs 17 and 18 contain corresponding bores which engage pins (not illustrated further) of the mounting bracket 12 in order to enable the pivotable mounting.
  • the roller shutter armor is lowered, the roller shutter belt 5 is placed on the deflection roller 46 on the side facing the user.

  • the rear friction roller 36 is inserted from the front between the two boards 13 and 14, taking the roller shutter 5 and moves in the direction of the flange 15. After reaching the target position, the axis 37 is inserted.
  • the roller shutter belt 5 now shows the course as illustrated in FIG. In this arrangement, the roller shutter belt 5 runs with a very large wrap angle of more than 180 °, almost 270 ° around the friction roller 36 around. Also, the wrap angle of the friction roller 39 is relatively large, for example, greater than 90 °.
  • the shell 11 is attached, with its side walls 13 and 14 comprise the boards from the outside. After attaching the housing shell 11, the two axes 37 and 39 are necessarily secured axially.
  • a retrofittable drive device for a roller shutter belt has friction rollers for the entrainment of the roller shutter belt.
