Definitions

  • the present invention relates to a lateral upright for a flexible curtain handling door.
  • an accordion door comprises: - two U-shaped metal uprights, connected at their upper end by a beam supporting an actuating device essentially comprising a motor and a winding shaft for lifting straps, - a flexible curtain stiffened at regular intervals by horizontal reinforcing bars, and - lifting straps fixed at one end to the lower reinforcement bar of the flexible curtain and, at the other end, to the winding shaft which is rotated by the motor.
  • the lifting straps preferably pass through guides arranged on some of the rebar.
  • Some of the reinforcing bars, including the lower bar have a roller at each of their ends serving to guide the lateral edges of the curtain in the U-shaped uprights and protecting said edges from wear which would result from their direct contact with said amounts.
  • the flexible curtain comprises on each of its lateral edges a strip made of a flexible material applying against the bottom of the U-shaped lateral uprights, said strips having a width greater than the length of the rollers.
  • They can be formed either by a rubber ribbon possibly having notches in the width direction, or by the stacking and the assembly of at least two of these notched ribbons, the notches being able to be offset with respect to the others, either by a brush with long and flexible bristles, or by the lateral edges of the curtain themselves which have been extended for this purpose, or finally by any other flexible material, in any form whatsoever, capable of ensuring the same functions.
  • the object of the present invention is to overcome these drawbacks.
  • a lateral upright for a handling door comprising a flexible curtain with vertical deployment, intended for guiding the lateral edges of said curtain, comprises a U-shaped metal profile, a lining made of a material which is poorly conductive of heat. , covering the interior of said profile, and at least one longitudinal cavity forming an air mattress between the exterior surface of said profile and the interior surface of said lining.
  • a lateral upright is provided with heating means which make it possible to maintain its parts which are in contact with one of the edge of the curtain and the sealing strip adjoining it at a temperature above the freezing temperature.
  • heating means can be constituted by electrical resistors placed inside the lateral guide, or incorporated in the lateral guide.
  • the air contained in the cavities of the upright can, for example, be heated by the cold production devices of this store, such as compressors or heat exchanger batteries.
  • the accordion door shown in Figure 1 further comprises a sealing member which consists of two sealing strips 10 fixed respectively on each of the side edges of the flexible curtain. These sealing strips each consist of a brush with flexible bristles, long enough to come into contact with the bottom of the lateral uprights 1.
  • the brushes 10 therefore have a width greater than the length of the rollers 9.
  • FIGS 2 to 6 show various embodiments of an amount 1 provided to equip an accordion door like that which has just been described above (and more broadly any type of handling doors).
  • the upright 1 shown in Figure 2 is half embedded in a wall. It consists of a metal U-shaped profile 11 lined internally with a lining 12 made of a thermal insulation material.
  • the parallel planes 13, 13 ′ of the profile 11 comprise a double wall delimiting a cavity 14 extending over the entire height of said profile.
  • These cavities 14 each form an air mattress. It is planned to heat at least that of the two air mattresses which is enclosed in the upright 13 or 13 'located on the side of the door exposed to the cold. In this way, the thermal bridge effect generated between planes 13, 13 'exposed to very different temperatures is neutralized, at least partially.
  • the considered cavity can be heated by any suitable means, in particular by heating resistors 15 or by a circulation of hot air.
  • the heat generated by the compressors of the refrigeration units can be used for this purpose.
  • the cavities 14 can also be advantageously used for the passage and protection of electric cables 16 used in particular for supplying the motor driving the winding shaft of the straps.
  • only one of the parallel planes 13, 13 'of the U-shaped section 11 has a double wall. When the door is mounted, it is this double-walled plane, therefore capable of receiving heating means 15, which is arranged on the side of the door exposed to the cold.
  • the lining 12 lining the profile 11 has, thermally, an effect complementary to that of the heated air mattress enclosed in at least one of the uprights 13, 13 '. Thanks to it, the effects of the thermal bridge created in the amounts exposed to different temperatures is completely neutralized.
  • this lining is made of polyurethane foam to which a surface treatment has imparted a rigid or semi-rigid envelope. Depending on the material in which it is made, it has a thickness of between about half a centimeter and about four centimeters. It is secured to the U-shaped profile 11 by any suitable means, in particular by gluing.
  • the lining 12 also has the function of limiting the wear of the curtain 6 at its lateral edges as well as the wear of the sealing strips 10 (constituted in FIG. 2 of a brush with long and flexible bristles) which there are subject.
  • the inner wall of the lining 12 is treated so as to be perfectly smooth. In this way, one can possibly consider not lining the ends of the reinforcing bars 7 with rollers 9, said rollers having precisely the function of preventing friction of the curtain at its lateral edges against the parallel planes, generally rough , amounts 1.
  • FIG. 3 represents a second embodiment of an upright 1 according to the invention. This amount differs from the previous in that the parallel planes 13, 13 'of its metal profile 11 do not have a double wall.
  • Chutes 17, metallic, welded inside said planes, serve to delimit cavities 14 inside of which at least one plans to optionally place heating means 15 and / or to pass cables 16 , as described above with reference to FIG. 2.
  • the lining 12 is identical to that which is shown in FIG. 2, except that it has a longitudinal groove 18 in each of its parallel planes, for housing chutes 17. It will be noted that the sealing member 10 shown here is constituted by the extension of the edge side of the curtain itself.
  • only one of the parallel planes 13, 13 ′ of the U-shaped profile 11 comprises a chute 17.
  • this plane provided with a chute 17, therefore capable of receiving heating means 15, which is arranged on the side of the door exposed to the cold.
  • FIG 4 shows two variants of a third embodiment of an amount 1 according to the invention.
  • the upright 1 comprises a simple metal U-shaped section 11, coated on the inside with a lining 12.
  • the lining 12 is made of a material that is a poor conductor of rigid or semi-rigid heat. It consists of a gutter 19, of U-shaped cross section, on the outer surface of which are fixed vertical spacers 20 intended to keep the gutter 19 away from the U-shaped profile 11 and to define a series of cavities 21 enclosing as many columns of air.
  • the gutter 19 and the adjoining spacers 20 are advantageously obtained by molding or by extrusion of a plastic material such as PVC.
  • the thickness of these parts varies between three and ten millimeters depending on the nature of the material used and the height of the upright 1.
  • the spacers 20 'and 20 "closing the cavities 21 located at the edges of the profile 11 have two ribs 22 parallel intended to pinch said edges.
  • the lining 12 can be made in one piece (FIG. 4 a ) or several pieces (four in FIG. 4 b ) having a trapezoidal cross section.
  • Advantageously pieces 12 a, 12 b , 12 c, 12 d are held relative to each other by a quick fastening system.
  • At least one of the cavities 21 may include heating means 15 and be used for the passage of cables 16.
  • the uprights 1 shown in Figures 5 and 6 have a simple metal U-shaped profile 11 covered with an inner lining 12.
  • This lining 12 is made of a material which is poor conductor of heat, comprising inner longitudinal cavities 23 ( Figure 5 ) or longitudinal grooves 24 on its outer surface delimiting longitudinal cavities 25.
  • the cavities 23 and 25 trap air mattresses capable of being heated by electric resistors 15 or by a circulation of hot air.
  • the cavities 23, 25 can also be used for the passage of cables electrically 16.
  • the linings 12 shown in FIGS. 5 and 6 are made of polyurethane foam to which a surface treatment has constituted a rigid or semi-rigid envelope.
  • These linings 12 can also be made of polyurethane foam covered with a rigid or semi-rigid plastic envelope, such as PVC. They are one to four centimeters thick. These fittings, like that shown in Figure 4, can be made in one piece ( Figure 5 a and 6 a ) or several pieces 12 a, 12 b, 12 c, 12 d ( Figures 5 b , 6 b ) having a trapezoidal cross section.
  • the amounts according to the invention therefore have, compared to the embodiments of the prior art, many advantages among which the most important are: - the neutralization of thermal bridges arising from the temperature difference existing between the two parallel planes of metal U-shaped profiles exposed to very different temperatures. The conditions favoring the formation of frost and ice in the door jambs are no longer met; - a substantial reduction in friction by creating smooth surfaces greatly limiting wear on the edges of the curtain and the adjacent sealing strips; - the gain made on the cost price of the doors, due to the elimination of the rollers which have become useless.
