Definitions

  • the present invention relates to liftable curtain doors of the kind comprising a frame formed by two vertical uprights joined at their upper parts by a horizontal crosspiece supported by said uprights, and in which crosspiece is housed a winding shaft, or curtain itself- even constituting the liftable door, or straps to raise the curtain with an accordion folding.
  • the curtain can be reinforced with horizontal bars.
  • the uprights can be used as slides for the edges of the curtain, and if necessary, the ends of the reinforcing bars.
  • an electric motor is used to drive the winding shaft in rotation, in particular a brake motor, which blocks rotation when it is not turning.
  • the slides In doors where the curtain folds in an accordion at the top, the slides must have a certain width to receive, at the top, the superimposed edges of the curtain, over a certain number of folding thicknesses, and / or the ends accumulated reinforcement and stiffening bars of the curtain.
  • the width of the slides is then simply that of the thickness of the curtain, if necessary the thickness of a reinforcing bar.
  • the present invention relates more particularly to a rolling type curtain door, and provides uprights having a section larger than that which is necessary in this case.
  • the uprights can thus have sufficient strength to support the cross member and define a usable interior volume.
  • the subject of the present invention is a handling door with a curtain which can be lifted up by winding, comprising a frame formed by two vertical lateral uprights, joined at their upper parts by a horizontal crosspiece carried by said uprights, said crosspiece sheltering a tree of winding of the curtain, the uprights forming slides or comprising slides for the vertical edges of the curtain, the winding shaft being rotated in one direction or the other by an electric motor advantageously of the brake type arranged vertically and attacking the winding shaft by a bevel gear, characterized in that the electric motor is housed inside one of the uprights, preferably in the vicinity of the top of this upright.
  • the door comprises at least one transmission support block forming a reduction gear and angle gear, fixed to the frame, either to the cross member, or to an upright to support and fix the winding shaft. , and the motor, or another accessory such as limit switch or counterweight.
  • the door comprises a crank connected to the winding shaft by means of an electrically controlled clutch, and is characterized in that it comprises means for establishing the connection between the winding shaft and the crank in the event of a power failure, and to release the motor brake, and means for disengaging the crank from the winding shaft in the event of current being present.
  • the part of the upright housing the engine comprises on a accessible face a removable panel or cover allowing, by removal, to access the engine for maintenance, repair or replacement, and is characterized in that the lower edge of the removable cover , in the closed position, is moved away from the wall of the upright which it garnishes, to form a switch slot for bringing the edge of the curtain into the slide in case it has come out.
  • the support block includes an additional output shaft for winding the cable of a counterweight.
  • This may be in several elements arranged one on top of the other, the elements being of different transverse dimensions, increasing from the bottom upwards, means being provided on the path of the counterweight to stop the elements separately at different heights.
  • the device shown by way of example in FIG. 1 comprises a frame, or gantry, formed by two vertical uprights 2, 3, joined at their upper parts by a horizontal cross member 1 supported by said lateral uprights 2 and 3, which also serve of slides to a flexible lifting door (not shown) constituted by example by a sheet of plastic material reinforced by rigid horizontal or elastically flexible crosspieces.
  • the door is wound on an upper horizontal shaft 4.
  • the shaft 4 is rotated by an output shaft 5A of an electric motor 5, mounted vertically in the upright 2 of the door frame, by means of an angle return block 6 forming a reducer, fixed to the upper part of the upright 2 or to the cross member 1 and serving both as a support for the motor and as a support bearing for the winding shaft.
  • the operation of the motor in one direction or the other ensures the raising and lowering of the curtain door by winding and unwinding of the curtain itself.
  • Another bearing 7 supports the other end of the shaft 4 and can be provided with an end-of-travel control member 8.
  • One can also provide a counterweight as will be described below.
  • the operation or stopping of the electric motor can be controlled by actuation of a push button, or by any automatic system, such as a photocell system or detection loop, etc.
  • the electric motor can advantageously be of the brake motor type , blocking the curtain in the raised or lowered position when the engine is not running. Stopping the curtain in position can also be obtained by mechanical means. When the motor is not energized, in the event of a power failure for example, it is advantageous that the curtain can be raised or lowered without encountering significant resistance from the motor.
  • the door of the invention comprises a manual actuation device usable in the event of a power failure.
  • the motor shaft is extended downwards by a shaft 9 provided at its end with a bevel gear 10 and a crank 11.
  • a clutch clutch there is provided for safety a clutch clutch, so that the crank 11 actuates the shaft 9 only if the crank is pressed on its axis against the force of a spring for example.
  • a universal joint 12 can be provided to accommodate misalignments.
  • an electrically controlled clutch 13 which is disengaged, that is to say which decouples or separates the motor from the crank, when the the assembly is under electric voltage and which, on the contrary, couples the motor shaft, therefore also the winding shaft 4, with the control of the crank when the assembly is no longer supplied with electric voltage, for example power failure, power off, etc.
  • the motor When the electrical supply is normal, the motor, however it is controlled, raises or lowers the curtain door, and, by its stop brake function, keeps the door in a raised or lowered position, or other intermediate position, when its power is cut, while it remains energized for the correct operation of the brake motor. Under these circumstances, the installation is energized, and the clutch 13 is disconnected. The crank is isolated from the motor. It is not driven or acted upon by it when it turns. No more when it is stopped. The device therefore poses no risk to personnel who may pass in the vicinity, or who may inadvertently operate the crank.
  • the clutch 13 connects together, for example under the action of a spring or gravity, the motor output shaft 5A and the shaft 9 of the crank, while the engine brake is released, and the winding shaft 4 can rotate freely when driving with the crank 11.
  • the bevel gears can be provided so that the drive cannot be transmitted only from the crank 11 to the shaft 4 and not in the other direction.
  • the curtain door will therefore remain in the position it is in, as long as no one operates the crank.
  • a counterweight can be provided, to lighten the maneuver, both manual and with the engine.
  • crank has been shown coupled on the axis of the motor, which allows a construction of reduced volume. It is however understood in the context of the present invention that the crank drives the winding shaft 4 independently of the motor, provided that it is by means of a clutch of the type described above.
  • the embodiment of the handling door shown in Figures 2 to 5 comprises a frame formed by two lateral vertical uprights 2, 3 and a horizontal cross member 1.
  • the cross member is carried by the uprights and is fixed to them to join them rigidly.
  • the cross member contains a winding shaft 4 of a curtain 25, stiffened by rebar 26.
  • the uprights form slides 27, for the edges of the curtain and the ends of the rebar.
  • the uprights have, on their face opening side of the door, inclined walls 18, 19 facilitating the retraction of the curtain and bars in the slides if, for any reason, an edge of the curtain is out of its slide.
  • the curtain passes through a slot 20 in the lower horizontal part of the crosspiece.
  • the cross member has been shown above the uprights. It can also, in a well known manner, be placed against the upper part of the uprights, which leads to providing a substantially horizontal reference for the curtain near the winding shaft.
  • the electric motor 5 for winding the curtain is placed vertically and is housed inside one of the two uprights 2, 3, in the vicinity of the upper part thereof.
  • the motor is fixed to a block or module 6 of transmission-reduction, forming a bevel gear and reduction gear. speed, and supporting, in addition to the motor, the curtain winding shaft.
  • the module 6 is itself fixed to the door frame, for example, as shown in FIG. 5, at the left end of the horizontal cross member 1.
  • the axis of the motor can be connected to a rod 5A serving for a emergency operation, such as a crank, with any appropriate security system.
  • the opposite end of the winding shaft can be fixed to an identical or symmetrical module, itself fixed to the door frame.
  • This second module carries the shaft, and on the other output, it can carry an end-of-travel accessory, for example a spring or the like.
  • Another output can also be provided on the module, for winding the cable of a counterweight.
  • the upper part of the front face 14 of the upright is cut out and a removable cover 15, which can be articulated at the top on the crossmember by example, is placed to protect the motor.
  • a similar arrangement can be provided on the second upright, for reasons of aesthetic symmetry.
  • the cover 15 is produced so as to participate in the arrangements for returning the curtain to its slide when it is out of it.
  • the lower edge 15A of the cover is formed by a downward extension which is spaced from the upright against which it is normally folded down to form a slot 15B in which the edge of the curtain, if it has come out of the slide 27 , is driven during its ascent, and is thus guided to enter the slide, by the oblique shape 15C of the edge of the cover above this slot 15B, and by an oblique groove 15D provided at this location on the oblique face 18 of the vertical lateral upright.
  • the reinforcing bars 26 of the curtain are preferably flexible so as to come out of the slide without permanent deformation, under the effect of abnormal stress, if for example a carriage strikes the curtain before it is completely raised.
  • an additional output 23 of the transmission block for the winding of a counterweight cable, sheltered by a casing 24.
  • the counterweight can be made up of several elements of different horizontal sizes to stay hooked at different heights when lowering the counterweight, and adapt its heavy weight to the weight of the length of unrolled curtain. Under these conditions, it is possible to have a balance height at the stop level of one of the counterweights, height allowing passage in the event of an emergency.
