Definitions

  • the invention relates to a door operator according to the preamble of the main claim.
  • a known door drive for a garage door of this type the support with the electric motor is fastened to the ceiling inside the garage at a distance from the door opening.
  • An endless chain is guided between a deflection wheel held at the garage opening above the garage door and the drive wheel.
  • the garage door is guided near its upper edge on both sides into guide rails extending into the interior of the garage and connected to the chain at its upper edge.
  • the electric motor is switched on to open the gate.
  • the drive wheel rotates in such a direction that the chain strand connected to the door moves into the interior of the garage and thereby pulls the door inwards in the guide rails.
  • the lower edge of the door swivels to the garage ceiling and opens the garage opening.
  • the direction of rotation of the electric motor is reversed to close the door. This will get you out of the garages deep chain chain moves the gate into its closed position.
  • a tension and compression spring with shock absorber function is switched on in the connection between the garage door and chain to avoid damage to the electric motor or a gear connected to it.
  • the garage door is pulled over this spring when opening and pushed when closing, the spring having to be designed very hard because of the large mass of the garage door.
  • the door drive according to the invention with the characterizing features of claim 1 achieves a largely uniform running of the garage door when opening and closing, in which the so-called gate swing is also switched off.
  • Load impacts that occur which are primarily triggered by the guide mechanism of the garage door, are kept away from the transmission and the rotor of the electric motor and are absorbed by the chain and drive wheel in a damped pivoting movement of the motor housing. Damage to the engine and possibly the gearbox is thus avoided, even in the long term.
  • the damping elements for absorbing the impact energy are extremely inexpensive as simple elastically deformable plastic parts and the known spring links between the chain and the garage t or superior both in terms of function and in terms of low production costs.
  • FIG. 1 shows the interior of a garage 10 with a garage opening 12 closed by a garage door 11.
  • Two guide rails 14 extend into the inside of the garage near the garage ceiling 13 on both sides of the garage door 11.
  • Rollers 15 run in the guide rails 14 and are rotatably mounted on both side edges of the garage door 11 near the top edge 16 of the door.
  • a motorized door drive 17 which consists of an endless chain 19 stretched under the .. garage cover 13 and a drive unit 20 fastened to the garage ceiling 13 for: the endless chain 19.
  • the endless chain 19 is guided on two deflection wheels, one deflection wheel 18 being fastened to the lintel 22 of the garage opening 12 and the other deflection wheel being arranged in the drive unit 20.
  • the garage door 11 is connected to the lower chain strand 191 of the endless chain 19 via a rod 21 articulated on the upper edge 16 of the door.
  • the drive unit 20 which is covered in FIG. 1 with a protective hood 23 with a passage opening for the endless chain 19, is shown in detail in FIGS. 2-4.
  • the drive unit 20 has a carrier 24 on which a geared electric motor 25 is held.
  • the electric motor 25, not shown in detail, has a housing 26 from which a drive wheel 27 formed as a chain wheel protrudes, which guides the endless chain 19 as a second deflection wheel and at the same time drives it in accordance with the respective direction of rotation.
  • a reduction gear 29 is arranged between the rotor shaft 28 of the electric motor 25, indicated by dash-dotted lines, which, like the electric motor part of the electric motor 25, is enclosed by the housing 26.
  • the drive wheel 27 sits rigidly on the output shaft 30 of the reduction gear 29.
  • the electric motor 25 is designed to be reversible in the direction of rotation, so that the drive wheel 27 is in the inverse direction of rotation can rotate.
  • the housing 26 is mounted so as to be pivotable about the axis 31 of the drive wheel 27.
  • the bearing is designed as a slide bearing 32, which is arranged concentrically with the axis 31 or the output shaft 30.
  • the slide bearing 32 has a slide ring 33 which is screwed concentrically to the output shaft 30 to the housing 26.
  • the sliding ring 33 rests with an edge zone 34 on a flange 3-5 protruding at right angles from the carrier 24, and engages with a centering collar 36 through a circular opening 37 in the flange 35.
  • a ring 39 inserted in an annular groove 38 in the sliding ring 33 secures this lubricated plain bearings 32.
  • the housing 26 is fixed by means of a reset device 40 in a basic position "0", which is indicated schematically in FIG. 4 is symbolically indicated by the movement arrows.
  • the resetting device 40 has a spring member 41, which engages on the housing 26 on the one hand and on the carrier 24 on the other hand, which is designed here as an elastically deformable element 42 made of plastic (polyurethane) or rubber.
  • the housing 26 is pivoted, the housing 26 is supported on the carrier 24 with elastic deformation of the element 42. After the pivoting force ceases, the compressed element 42 pushes the housing 26 back into the basic position "O".
  • the elastic element 42 which is fixedly connected to the housing 26 has two buffers 43 which bear against stops 44 on the carrier 24, which are formed here by the carrier 44 itself, without play.
  • the buffers 43 are attached to mounting bolts or screwed to a metal plate 45 (- 3 Fig. 2), which in turn is rigidly connected to the housing 26th A buffer 43 is effective in a pivoting direction of the housing 26.
  • the door drive described above ensures that the garage door 11 runs largely uniformly during the opening and closing movement. Every jolt or impact caused by the guiding mechanism of the garage door 11 during the door movement is conducted via the endless chain 19 and the drive wheel 27 into the output shaft 30 and causes the housing 26 in the slide bearing 32 to pivot Housing 26 is pivoted in one or the other direction indicated by arrows in FIG. 4, the buffer 43 effective in the respective pivoting direction being elastically deformed by being compressed. In this way, the impact energy is converted into deformation energy of the buffer 43 and largely reduced. Then the buffer 43, which is now expanding again, pushes the housing 26 back into its basic position "0" (FIG. 4).
  • the reset device 40 with its two simple shock-absorbing elements 42, 43 is structurally simple and very inexpensive to manufacture, an additional advantage over previously known spring links between the drive chain and the garage door.
