Definitions

  • the invention relates to a door lifting device with vertical movement and relates more particularly to a security system for such an installation.
  • a door of the type concerned by the invention comprises a panel guided between two parallel rails extending respectively along the sides of the doorway and fixed to the wall.
  • the panel has guide wheels secured to move in the grooves of these rails.
  • the panel is operated by two flexible links (typically straps, but possibly cables, chains or the like) extending respectively opposite the rails, on either side of the panel.
  • Each operating link is thus attached between an anchoring point secured to the panel, (generally located at the bottom of the latter) and a reel, or similar operating means, most often installed in height, above the door.
  • the operating links are normally always tensioned at least by the weight of the panel itself.
  • This panel can be balanced, at least in part, by springs arranged co-axially to the reel shaft.
  • the invention achieves this objective by triggering a safety mechanism, as soon as the holding torque disappears.
  • the invention relates to a door lifting device with vertical movement, of the type comprising a reel driven by an electric motor and adapted to actuate operating links attached to said door, characterized in that said motor is coupled to a intermediate piece mounted with a predetermined rotary clearance on a fixed support of said reel and in that a pivoting pawl is mounted in the vicinity of said reel so as to be able to pivot in a predetermined position, suitable for making it cooperate with a stop of said reel, when said piece intermediate moves in rotation following a failure of the door retainer.
  • the pawl is mounted on the fixed support and is coupled by a lug or the like to the intermediate piece.
  • the latter is located in the axial extension of the reel shaft and the axis of rotation of the latter is coincident with that of said shaft.
  • the intermediate piece or said fixed support has oblong holes substantially equidistant from the axis of said reel, while the fixed support or said intermediate piece, respectively, comprises guide elements, for example constituted by bolts or the like, engaged in said oblong holes.
  • the intermediate part comprises the oblong holes
  • the fixed support comprises the guide elements.
  • the pivoting pawl is mounted on a pin fixed to the fixed support and its lug is engaged in a hole in the intermediate piece, so that the rotation of this intermediate piece causes the lug to pivot in the direction of the stop. provided on the reel shaft.
  • the lifting device is only partially represented, namely more particularly one of its ends showing the reel and its drive shaft.
  • Each strap is wound on itself in a grooved pulley 12 of the reel 14 secured to a horizontal shaft 16 installed above the door and driven by an electric motor 17.
  • Each strap is thus normally tensioned between the door and the reel 14.
  • the shaft is provided with a cylindrical seat 18 mounted for free rotation in a bearing 19, itself secured to a fixed support 20.
  • the shaft 16 is advantageously a hollow shaft housing the electric motor 17 and a mechanical reducer 22, of a relatively irreversible type.
  • the body of the motor 17 is integral with the reduction gear 22 (these two elements are mounted in the extension of one another) and the axis of the motor is provided with a rod with square section 24 which projects axially beyond the end of the hollow shaft.
  • the motor body is not linked to the wall of the shaft 16.
  • the reduction gear is coupled to this shaft, internally. More specifically, the shaft 16 is shaped so as to have large grooves extending longitudinally. These grooves therefore define internal stops 26 by which the mechanical coupling takes place with the reducer and external stops 28 (here four in number) whose role will be explained below.
  • the motor 17 is coupled (by its rod with square section 24 by means of a pin 30) to an intermediate piece 34 mounted with a predetermined rotary clearance on the fixed support 20 of the reel 14.
  • a pivoting pawl 36 is mounted in the vicinity of said reel. It is arranged to be able to pivot in a predetermined position suitable for making it cooperate with one of the stops 28 of said reel, when said intermediate piece 34 moves in rotation following a failure of the door retaining means, for example a disappearance torque or a break in the balancing systems.
  • the pawl 36 is mounted on the fixed support 20, by means of a pin 42 formed from a bolt fixed to the fixed support 20.
  • the pivoting pawl 36 includes a lug 44 engaged in a hole 45 of said intermediate piece.
  • the latter has a general trapezoidal appearance; it is constituted by a sheet comprising several folds parallel to 90 ° with respect to each other. It is located in the axial extension of the hollow shaft 16, so that the axis of rotation of said intermediate piece is coincident with that of the hollow shaft and, therefore also, that of the rod with square section. This is obtained by the fact that the intermediate part has oblong holes 38, while the fixed support comprises guide elements 40, here constituted by simple bolts engaged in the corresponding oblong holes 38.
  • the guide elements 40 and the holes 38 are equidistant from the axis of the reel.
  • the electric motor is also integral with the intermediate piece, the connection being produced at the center of rotation of the latter by the assembly described above, including the square section rod and the pin 30 locked between two parallel parts of the intermediate piece 34.
  • the pin 42 itself crosses an oblong hole 43 of the intermediate piece, so as not to impede the movement of the latter.
  • a spring 48 is mounted between said fixed support 20 and the intermediate piece 34. As can be seen in FIG. 1, this spring normally maintains the intermediate piece in a stable position in which the guide elements 40 are in abutment at certain ends of the corresponding oblong holes 38. For this position illustrated in FIG. 1, the pawl 36 is moved away from the hollow shaft 16, its position being determined by the cooperation between the lug 44 and the hole 45 of the intermediate piece 34.
