Definitions

  • the subject of the present invention is a reinforcing and guiding bar for a flexible curtain of a door with vertical lift.
  • the flexible curtain In a first type of door, the flexible curtain is designed to be raised by winding around a shaft driven by a motor and overhanging the door. When it is raised, the curtain remains in a vertical plane and the lateral slides which hold it there are therefore of small width.
  • the flexible curtain In a second type of door, the flexible curtain is designed to be raised by winding around a bar fixed to its lower edge.
  • Two straps (at least) form a loop around the curtain, one end of which is secured at a fixed point located at the door lintel and the other end of which is secured to a shaft overhanging the door, said shaft being driven in rotation by a motor.
  • the straps cause, when wrapped around the tree, the curtain wraps around the bar and consequently, its lifting.
  • the width of the side rails is at least equal to the diameter of the curtain completely rolled up.
  • the flexible curtain is designed to be raised by folding accordion. It comprises several horizontal hinge bars, regularly spaced, to which are fastened loops for the passage of vertical straps, one end of which is fixed to the lower hinge bar and the other end to a shaft driven in rotation by a motor and overhanging the door. As during the opening of the door the curtain forms a bundle of folds of increasing volume, the width of the side rails is at least equal to that of the fully folded curtain.
  • the flexible curtain has a bar fixed to its lower edge. It comprises (in the case of accordion doors) or may include (in the case of the other two doors mentioned) also horizontal reinforcing bars, regularly spaced, intended to stiffen it. These reinforcing bars, which are generally slipped into sheaths practiced on one of the faces of the curtain, are essential when the curtains have a large surface and they are part of doors giving on the outside, exposed to the winds. This is particularly the case for quick-action doors, called “handling doors", giving access to warehouses and similar storage rooms.
  • the lower bar and, possibly, the reinforcing bars which penetrate into the side rails prevent the curtain from coming out of the plane of the door when it is subjected to a thrust. If this mode of action of the bars is desirable and even sought when the curtain is subjected to a thrust regularly distributed over its surface (case of the wind), on the other hand it is harmful when the curtain is subjected to a violent thrust acting on a reduced surface.
  • the above-mentioned handling doors which are opened and closed several dozen times a day to allow passage to handling and / or transport vehicles, are particularly exposed to thrusts of this type.
  • the present invention relates, which defines a reinforcing and guide bar for a flexible curtain of a door with vertical lift, said bar allowing the curtain to escape from its lateral guides when it is subjected to a push of a certain force.
  • the subject of the invention is a handling door, comprising two lateral vertical uprights forming slides supporting a lintel beam, and a flexible curtain with vertical lift, comprising at least one horizontal reinforcing bar, to stiffen the curtain, and the ends penetrate the rails to keep the curtain in the plane of the door, characterized in that said bar has at each of its ends a zone of less mechanical resistance such that it escapes from the rails when it is subjected to a substantially thrust perpendicular to the curtain, of a determined force.
  • This upright is constituted by a vertical U-shaped profile which can be load-bearing and support the end of a beam forming a lintel.
  • the essential function of the upright 1 is a function of guiding one of the lateral edges of a flexible curtain 2 to which is (are) subject (s) one (or more) sheath (s) horizontal (horizontal) 2 ′.
  • a reinforcing bar and guide comprising a tube 3 whose length is less than the distance separating the opening of the two uprights 1 located opposite.
  • a protective tip 4 At each end of the tube 3 is fixed, by fitting, a protective tip 4 whose length is such that a bar consisting of a tube 3 provided with two protective tips 4 is longer than the distance separating the opening of the two uprights 1. Each protective end piece 4 therefore enters the corresponding upright 1 and prevents the curtain 1 from coming out of the plane of the door.
  • the essential characteristic of the protective caps 41, 42, 43, shown respectively in FIGS. 1, 2, 3, is that they do not prevent the curtain 1 from coming out of the plane of the door, that is to say out of the uprights 1, only under normal operating conditions.
  • the curtain of a closed door subjected to the action of a very wind violent will it remain in its place, that is to say contained in the space delimited by the uprights 1.
  • the protective end caps 41, 42, 43 are provided to let the curtain escape from the uprights 1 , in case the curtain is struck with force, as by a vehicle.
  • the protective end piece 41 represents in FIG. 1 consisting of an oblong body made of a flexible plastic material, force-fitted into the end of the tube 3.
  • This end piece is advantageously cylindrical over at least the part of its length intended to be fitted into the end of the tube 3, the diameter of this cylindrical part being slightly greater than the inside diameter of the tube.
  • the protective cap 42 shown in FIG. 2, comprises an oblong body 421, made of a rigid plastic material, at one end of which is connected, by means of a throttle 422, a sphere 423. At its other end, the body 421 carries a cylindrical bulge 424 intended to prevent the friction of the curtain 2 and of the sheath 2 ′ against the inner surface of the wings 11, 12, of the profile 1.
  • the protective end piece 42 is force fitted into the tube 3 over a length such that the end of the tube is located at the constriction 422.
  • the protective cap 43 shown in FIG. 3, comprises a head 431 connected to a cylindrical sleeve 432 by a thin spacer 433.
  • the sleeve 432 covers the end of the stiffening bar 3.
  • the protective cap 43 is made of a rigid breakable material so that, if the head 431 comes to strike with a certain violence one of the wings 11, 12 of the upright 1, it breaks in two at its spacer 433.
  • the protective tip of the bar according to the invention that it folds, that it dislocates or that it breaks when it is stressed with a certain force, therefore cooperates with lateral slides to ensure a function guiding a flexible curtain under the normal operating conditions of a handling door; it also provides a protective function for the flexible curtain and the tubular portion of the reinforcing bars which, if necessary, stiffen it when said flexible curtain is subjected to a shock of a certain violence. It is easy to manufacture, being advantageously made of a molded plastic material, and its installation and replacement are particularly simple.
