Definitions

  • the present invention relates to a flexible door, that is to say a door comprising a flexible sheet unwinding vertically in the plane of an opening so as to hide or unmask it.
  • One of the aims of the present invention is to produce a flexible door of a simple design and which ensures good tension of the flexible strip.
  • the flexible door comprises a frame with two vertical guides for a threshold bar on which is fixed one of the ends of a flexible sheet wound on a horizontal drum supported by a frame mounted at the upper end of the frame, said drum being connected by a kinematic link to a motor to control its rotation in one direction and in the other in order to close and open the door and is characterized in that the flexible sheet is constituted by a transparent sheet polyvinyl chloride guides having corresponding limit switches, one in the open position and the other in the closed position and cooperating with the threshold bar.
  • a transparent flexible door is produced, which has great advantages in many applications, using a material which is inexpensive, very solid, not very sensitive to abrasion, which has good transparency, the design of the door, despite the low stability of the material at the temperature difference ensuring good tension of the sheet in the closed position and a lift always corresponding to that initially planned.
  • the threshold bar is constituted by an H-shaped section whose core allows the fixing, at its ends, of bars fixed to plates supporting orthogonal axes on which idle guide rollers of the threshold bar in the vertical guides.
  • the upper edge of the threshold bar has a narrowed slot for receiving the free edge of the sheet which is integral with a bead ensuring its attachment to said threshold bar.
  • the lower edge of the threshold bar is secured to a flexible bead provided with channels connected to a sensitive element inserted on a circuit for controlling the opening of the door, so that any deformation of the flexible bead controls the opening of said door.
  • the limit switches include a movable arm projecting in the vertical guides and arranged at preselected locations on the path of the guide rollers of the threshold bar in said vertical guides.
  • the flexible door may comprise, along the vertical guides, on either side thereof, vertical plates provided with bristles cooperating with the vertical edges of the flexible sheet. This ensures the tightness of said door.
  • the flexible door shown in the figures comprises a frame, generally designated by the reference 1 and comprising two vertical uprights 2 supporting a frame 4 and against which vertical guides 5 are fixed.
  • the uprights 2 are connected by a cross-member 6 and the chassis 4 supports an electric motor 7 whose output shaft drives, through a variable speed drive 8, a pinion 9 over which passes an endless chain 10 cooperating with a pinion 11 wedged on a shaft 12 guided in bearings 14 of the chassis 4 and on which a drum 13 is wedged.
  • a transparent sheet 19 of polyvinyl chloride in the lower edge is secured to a threshold bar 15.
  • the threshold bar 15 comprises a profile (see FIG. 3) having a substantially H-shaped section with a core 16 and two bars 17.
  • the bars 17, in the vicinity of the upper edge, are folded to form a narrowed slot 18 traversed by the lower edge of the sheet 19, the latter being integral with a bead 20 whose section is greater than the width of the slot 18.
  • the core 16 is pierced with a series of regularly spaced holes 21, two of which, located at the ends, are intended to be crossed by screws 22 for fixing two bars 23 while the others allow the passage of screws 24 ensuring the fixing of a C 25 profile for holding a flexible bead 26.
  • the bars 23 are integral with a plate 29 supporting a pin 30 on which is mounted a roller 31, said plate comprising a cheek 32 supporting a pin 33 on which is mounted a roller 35, the axes 30 and 33 extending in two directions perpendicular to each other.
  • a tongue 34 One of the ends of the plate 29 is terminated by a tongue 34.
  • Two plates 29 are provided located at each end of the threshold bar 15 and which close the latter, these plates 29 being fixed by the screws 22 which are screwed into the corresponding holes of the bars 23.
  • the guides 5 are formed by profiles with a U-shaped section, the free ends of the wings face to face, the rollers 31 guiding the bar 15 against the inner faces of the wings, while the rollers 35 guide said bar 15 against the web of said sections.
  • the flexible bead 26 has three longitudinal channels 26a, 26b and 26c which are connected by tube 37 to a sensitive element 38 inserted on an electrical circuit which automatically controls the winding of the sheet 19 on the drum 13 if the bead 26 is crushed either laterally or at its lower end.
  • a sensitive element 38 inserted on an electrical circuit which automatically controls the winding of the sheet 19 on the drum 13 if the bead 26 is crushed either laterally or at its lower end.
  • the sheet 19 is subject to variations in dimensions due to temperature differences, it is ensured, thanks to the position of the limit switches 39 that the door will, in the closed position, be arranged so that the bead 26 flexible touches the ground, and in the open position always released at the same height. Indeed, the switches 39 being controlled by the rollers 15 and arranged at heights calculated so that the opening and closing of the door stop in determined positions, the possible variations in size of the sheet 19 will not modify these positions.
