Definitions

  • the present invention relates to a drive for the elevator shaft of a store or roller shutter with a wheel which can be driven by means of a strand, rotatably mounted in a stationary housing and which is gearingly connected to a driver which can be non-rotatably placed on the elevator shaft, one on a cylinder surface fixed to the housing rubbing helical spring brake surrounding the driver axially prevents the driver from rotating relative to the wheel, and furthermore an organ rotating with the wheel engages in the driver and releases the helical spring brake when the wheel is turned.
  • a drive of this type is known from DE-OS 32 11 506. It allows an extremely narrow construction, which is desirable when installing roller blinds, stores, roller shutters and the like. However, it has the disadvantage that the pulling force to be exerted by means of the strand is comparatively large with the usual diameters of the wheel. The diameter of the wheel cannot be increased arbitrarily to achieve a more favorable gear ratio, which is why this drive is not suitable for heavy sun protection devices such as stores and roller shutters.
  • the object of the invention is therefore to provide a drive of the type mentioned while largely maintaining the space-saving design, to be improved in such a way that the pulling force is lower and the drive can therefore be used for the blinds and roller shutters.
  • the end of an elevator shaft 1 of a store or roller shutter is rotatably mounted in a drive housing 2.
  • the housing 2 has a cover 3 with an inwardly facing bearing eye 4, which is provided with an external ring gear 5.
  • the cover 3 is firmly connected to the housing body 6.
  • a ball sprocket 7 is rotatably mounted, which is designed as a ring with an internal ring gear 8.
  • a disk-shaped member 9 is arranged axially to the elevator shaft 1, which carries at least one, preferably three, planet pinions 10, which are rotatably mounted thereon.
  • the planet pinions 10 mesh on the one hand with the outer ring gear 5 and on the other hand with the inner ring gear 8. If the ball chain wheel 7 is rotated, the planets run pinion 10 on the external ring gear 5 and rotate the member 9 at a lower peripheral speed than the ball sprocket 7.
  • the reduction ratio is approximately 1: 1.8.
  • a brake sleeve 11 is also firmly inserted, which forms a cylindrical inner surface.
  • a helical brake spring 12 is inserted axially into the brake sleeve 11, the ends 13 of which are angled inwards.
  • a driver 14 is further axially inserted into the helical spring 12, which has an inwardly projecting rib 15 which engages in a longitudinal groove 16 of the elevator shaft 1. The driver 14 is therefore rotatably connected to the elevator shaft 1.
  • the ends 13 of the helical spring 12 lie between the ends of the driver 14, which has a ring-shaped cross section. Between the two ends 13, an arm 17 of the disk-shaped member 9 engages and lies in the rotational path of the driver 14.
  • a ball chain is placed over the ball sprocket 7 and, as shown in FIGS. 4 and 5, is passed through the window frame 18.
  • a ball chain bushing 19 is screwed, which consists of two symmetrical halves, each screwed to the window frame 18 individually by means of screws.
  • the bushing 19 has a cylindrical bore 20 or 21 for the two strands of the endless ball chain, the diameter of which is only slightly larger than the diameter of the balls on the ball chain, the difference in diameter preferably being chosen such that the ball chain during lifting and Lowering the roller shutter just without noticeable friction losses can be pulled through the holes 20 and 21.
  • the length of the bores is at least equal to the center distance 22 of two adjacent balls of the ball chain.
  • Characterized in each position of the ball chain at least a Ku - gel so that no cold air can flow through this hole in the house interior in each of the cylindrical bores. 20 and 21
  • the chain bushing 19 is preferred made of plastic to avoid noise when operating the ball chain.
  • the ball chain in connection with the chain feedthrough 19 is thus able to eliminate the disadvantage known from the belt lift roller shutters, which is that the belt passage through the window frame cannot be closed in a windproof manner. On the other hand, like the belt elevator, it allows the roller shutter to be operated easily.
  • the housing 2 is mirror-symmetrical to the plane V - V. It consists of two parts, the parting plane of which forms the mirror plane in which the two longitudinal central axes of the bores 20 and 21 lie. This also halves the holes 20 and 21. Both parts can be individually attached to the fixed frame. As a result, the implementation after pulling the ball chain through the window frame 18 can be attached subsequently.
