Definitions

  • the present invention relates to a lifting curtain curtain door and more particularly relates to a prefabricated door for simplified installation.
  • Doors of this type generally have a frame formed by two vertical lateral uprights and an upper cross member.
  • the lateral uprights support the crossmember and form or contain slides for the edges of the curtain. They are fixed to the ground and their lower ends are thus maintained.
  • the upper crosspiece is used to maintain the spacing between the uprights at their upper ends and to house the mechanics. It contains a winding shaft, either of the curtain itself if it is the curtain that is rolled up, or of lifting straps if the curtain folds like an accordion at the top of the door.
  • the upper crossmember can also contain bearings to support said shaft, an electric motor, accessories such as a limit switch, automatic controls, etc.
  • the present invention aims to achieve a simplified mounting of such a door.
  • the invention aims to rationalize the constituents, limit the number and accelerate the establishment and operation of the door.
  • the subject of the invention is a lifting door with a lifting curtain, of the type comprising a winding shaft at the top and vertical lateral uprights forming or containing slides for the edges of the curtain, said vertical uprights having their lower ends fixed. on the ground, characterized in that each lateral upright comprises, at its upper part, a member for detachably receiving and supporting the winding shaft.
  • each lateral upright comprises, at its upper part, a member for detachably receiving and supporting the winding shaft.
  • the shaft is mounted so that it prevents the upper ends of the uprights from coming together, and in that a tensile-resistant element such as a spacer is stretched between the upper ends of the uprights to prevent them from s 'dismiss.
  • the cross member of the gantry for the door frame is virtually eliminated.
  • each upright carrying a shaft end, it is necessary to engage the winding shaft on the two shaft ends, at each of its ends. To achieve this, it suffices that one of the ends of the shaft is movable and can be retracted into the upright so that the winding shaft is brought into alignment with this end of the shaft, which is then pressed in the tree.
  • the shaft end provides the rotational connection and supports the shaft.
  • a good way to do this is to plan, in the upper part of each upright, a block containing mechanical elements such as a reduction gear, an output shaft of which constitutes said end of the shaft.
  • the gear unit is temporarily installed, without being screwed or bolted. It can be moved back when approaching the tree, then pushed back so that the end of the shaft engages in the winding shaft, and finally screwed or bolted in the final position.
  • the operation is very simple.
  • each upright comprises a mechanical reducer coupled on one side to the winding shaft.
  • one of the uprights On the other side of the mechanical reduction gear, one of the uprights has an electric motor to rotate the winding shaft and the other upright has a limit switch, to stop the motor, at the end of lifting or lower the curtain (some limit switches can operate without a gearbox; in this case, of course, there is none).
  • the door according to the invention comprises two vertical lateral uprights, of symmetrical structures, each comprising at a lower end means for fixing to the ground, and at the other upper end a box from which comes out a winding shaft connection. , and in the trunk, a speed reducer, and for an upright an electric motor, and for the other a limit switch.
  • a bay 2 In a wall 1 is cut a bay 2 and this bay can be closed or cleared thanks to a lifting curtain door.
  • This door consists of a flexible curtain reinforced at intervals by horizontal bars, and two symmetrical uprights, only one of which is shown in 3 in the drawings.
  • Each upright consists of a U-shaped metal part, which can be produced by a folded sheet. This form gives resistance to the upright and allows it to perform the function of a slide, or to contain a slide, for the edges of the curtain and the ends of the horizontal reinforcing bars of this curtain.
  • Each upright is provided at its base with a sole 4 properly fixed to the ground, for example by bolts 5.
  • the uprights can also be fixed to wall 1, as shown in diagram 6, at any suitable height.
  • the curtain can be wound at the top on a shaft 7.
  • the shaft 7 can wind straps 8, hooked to the lower bar 9 for reinforcing the curtain, and passing through rings 10, fixed to the reinforcement bars. 11.
  • FIG. 3 only one strap is shown, without curtain or bars, since this structure is well known.
  • the curtain is hung on a hanging bar 111 along its upper edge and can be raised by accordion folding at the upper part when the lifting straps 8 are wound on the shaft 7.
  • each upright is fixed, on a suitable support element such as a plate 12, a mechanical block 13 comprising a reduction gear, one side of which is connected to a shaft end 14, and the other side to a electric motor 15 on one upright, or a limit switch on the other upright.
  • a suitable support element such as a plate 12
  • a mechanical block 13 comprising a reduction gear, one side of which is connected to a shaft end 14, and the other side to a electric motor 15 on one upright, or a limit switch on the other upright.
  • the shaft 7 is engaged on two ends of the shaft 14 (in FIG. 3, only one is shown, the other being symmetrical).
  • the connection between the end of the shaft 4 and the shaft 7 provides the rotational connection and the support of the shaft.
  • the shaft 7 also prevents the uprights from approaching their upper parts, which may seem overabundant if the uprights are well fixed to the masonry of the wall. In any case, this guarantees against building work, sagging, etc.
  • This spacer can also be used to hang the curtain there (in the case where the curtain does not roll up), especially if the curtain, whose corners are attached to the uprights, must close off a fairly large span. This dispenses with a hanging bar.
  • This spacer can be bolted, possibly welded to the lateral vertical uprights (welding makes disassembly less easy).
  • Each upright may also include electrical components for controlling the motor, presence detector circuits with automatic controls, etc. fixed in the upright, or under the reducer support plate.
  • the separate uprights, the spacer, the winding shaft and the rolled curtain are brought to the site.
  • the assembly consists of erecting the two uprights and fixing them.
  • the mechanical elements are housed in the uprights. There is no cross between them, only the shaft and the spacer-hood. The rest is simple and quick.
  • the installation, or the descent of the winding shaft can be done by unscrewing one of the two reducers, depending on local facilities, because advantageously, the two uprights have a similar structure, with a reducer support and a window.
