  • each upright has a substantially U-shaped section, with a base substantially perpendicular to the wall and two branches extending from the base away from the bay to be closed, said slot is formed in the base and constitutes said slide, the interior of the U-shaped section thus being accessible so that it can be cleaned.
  • each upright has a substantially V-shaped section, with an apex close to the bay and two divergent branches which extend away from the bay from the apex, said slot is formed at the Mountain peak of the V and constitutes said slide, the interior of the V section being thus accessible so that it can be cleaned.
  • each upright has a substantially U-shaped section, with a base substantially parallel to the wall and two branches which extend away from the base, one of said branches being closer to the bay, said slot is formed in said branch closer to the bay and constitutes said slide, the interior of the U-section being thus accessible, so that it can be cleaned.
  • the slot of each lateral upright is advantageously bordered by lips substantially parallel to the curtain or rounded, and the branches of the U-shaped section of the uprights can have a horizontal length narrowed at the bottom.
  • the present invention relates to a door intended to close a bay 5 in a wall 9, separating two volumes of temperature air different T1, T2.
  • T1 can be + 20 ° C and T2 -40 ° C.
  • the door comprises an insulating curtain 4 which can be lifted by winding and two generally metal lateral uprights 1, 2, each provided with a slide 8 for guiding the curtain 4.
  • the lateral uprights 1, 2 are joined at their upper ends by a cross 3 which contains the curtain actuation mechanism, but this feature could be omitted without departing from the scope of the present invention.
  • the door shown in Figure 1 is of the type commonly called "handling door", that is to say a quick opening door intended to open to the passage of a handling machine and to close after the passage of said device.
  • Each lateral upright 1, 2 comprises a front wall 7, which here is substantially perpendicular to the curtain 4, and which is provided with a longitudinal slot 8 forming said slide.
  • the wall 7 does not necessarily have to be perpendicular to the curtain 4: it is sufficient for the wall 7 to be locally not parallel to the curtain 4 in the vicinity of the slot 8.
  • the lateral uprights 1 , 2 have a U-shaped section, and each have two walls 10 which extend a certain distance from said wall 7, towards the outside of the opening 5.
  • the lateral uprights can have a section equivalent to a U-shaped section, for example an H or V section.
  • Each lateral upright 1, 2 consists of two metal sections 26, 27 with an L-shaped section, which are separated by the slot 8. The section 27 of each lateral upright is in tight contact against the wall 9, so as to minimize the air passages through the opening 5.
  • the curtain 4 has lateral parts which slide in the slots 8 of the uprights 1 and 2.
  • the curtain 4 is flexible and can be lifted up by winding and comprises horizontal reinforcing bars 6 having axial ends 6a which slide in the slots 8 and the curtain has lateral edges 4a which also slide in the slots 8.
  • the curtain 4 may possibly not include reinforcing bars 6.
  • the side parts of the curtain which slide in the slots 8 may be adapted to disengage from said slots 8 during a violent impact on the curtain 4, so as to prevent damage to said curtain.
  • the lateral edge 4a of the curtain is provided with two sheets of elastic flexible material, fixed to the curtain 4 and extending in V towards the outside of the curtain.
  • the divergent branches of the V rests elastically on the front wall 7, each on one side of the slot 8, providing an excellent seal.
  • the flexible V-shaped sheets could be replaced by an advantageously hollow bead, forming the lateral edge of the curtain 4.
  • the door according to the invention can be actuated by mechanical or electromechanical means well known in the state of the art.
  • the curtain 4 can be raised in various ways and be produced in various ways without departing from the scope of the present invention, provided that it has lateral parts sliding in the slots 8.
  • Figures 2 to 6 give some non-limiting examples which explain some ways to lift the curtain.
  • the curtain 4 can be flexible and wind on a horizontal axis 11 in the upper part of the door.
  • the curtain 4 has lateral edges 4a, thickened or not, which slide in the slots 8 of the lateral uprights 1 and 2.
  • the curtain 4 could also include horizontal reinforcing bars, the ends of which slide or do not slide in the slots 8.
  • the curtain 4 can be folded in accordion.
  • the curtain 4 consists of rigid panels 14 which are articulated on horizontal reinforcing bars 6, one in two of which slides in the slots 8 of the uprights 1, 2.
  • the door further comprises vertical straps 12, attached to the lowest reinforcing bar 6b, and adapted to be wound on a horizontal axis (not shown) in the upper part of the door.
  • the highest reinforcement bar 6c (not visible in FIG. 3) is fixed, so as not to fall when the curtain 4 is lowered into the closed position.
  • the winding of the straps 12 causes the lower bar 6b to rise, which brings with it the other reinforcing bars 6 which slide in the slots 8, by folding the curtain 4 in accordion.
  • the rigid panels 14 can be panels separated from each other, articulated on the bars 6, or even be formed by a single flexible canvas or a sheet of flexible material common to the whole curtain 4 and stretched by spacers between the bars 6 .
  • the curtain 4 is constituted by a flexible wall provided with horizontal reinforcing bars 6, one in two of which slides in the slots 8 of the uprights 1, 2.
  • the lowest bar 6b is linked to straps 12 which are wound on an axis 13 in the upper part of the door.
  • the winding of the straps 12 on the axis 13 causes the lower bar 6b to rise, which brings with it the other reinforcing bars 6 which slide in the slots 8, by folding the curtain 4 in accordion.
  • the upper part 4b of the curtain is of course fixed, so as not to fall when the curtain 4 is lowered into the closed position. It will be noted that in this example, it would possibly be possible for all the reinforcement bars 6 to slide in the slots 8.
  • the lateral edge 4a of the curtain can be at a very short distance from the front wall 7 of the profile 27 close to the wall 9, so that the lateral edge 4a is substantially in sealed contact with the profile 27, at least when the curtain is lowered, in order to minimize the air passages through the opening 5.
  • the edge 4a of the curtain can comprise a strip of flexible material, such as a rubber strip possibly slotted in the direction of the release, which bears elastically against the front wall 10 of the profile 27. Examples of flexible curtain strips are given in document EP-A-0 194 494 of the applicant and in the corresponding American patent US -A-4 934 437.
  • the curtain 4 can also be produced differently. For example, as shown in Figure 5, it can be lifted without folding accordion or winding, but by simple translation upwards, possibly with a certain inclination relative to the vertical. In FIG. 5, the uprights 1, 2 are thus extended by inclined slides 15, 16. The curtain 4 can then be flexible, reinforced or not by horizontal reinforcing bars, or even made up of rigid articulated panels, etc. If the guide rails 15, 16 are in alignment with the lateral uprights 1, 2, the curtain 4 could even consist of a single rigid panel.
  • the curtain 4 can be made up of independent rigid panels 17, which are stacked in the upper part of the door when the curtain 4 is raised, as shown in FIG. 6.
  • FIG 7 there is shown the amount 1 of Figure 1, with a curtain 4 with thickened edge 4a which slides in the slot 8, separating two volumes of air at different temperatures T1 and T2.
  • the only possible heat exchange between the two air masses at T1 and T2 is by conduction through the section 27 in L, without any fin effect since one side of the profile 27 is in contact with the wall 9 and with the air mass at T2 while the other side is in contact with the air mass at T1: the heat exchanges therefore take place through a much more limited surface than in the prior art, where the upright generally has a rear wall in place of the opening 34 so that the upright forms a fin for dissipating heat .
  • the U-shaped section of the upright in Figures 1 and 7 makes it easy to clean the upright substantially completely, which is very important in all places where strict hygiene must be maintained, for example cold stores for food, pharmaceutical laboratories, etc.
  • the front wall 7 which is close to the bay 5 and therefore which is likely to come into contact with objects or people crossing the bay 5, can be cleaned on both sides: a first side 7a directed towards the curtain 4, and on a second side 7b opposite the curtain 4, because these two sides are easily accessible.
  • the side 7b is accessible through the opening 34 of the upright, between the two side walls 10.
  • the U-shaped section of the uprights like other profiled sections, gives them good mechanical resistance.
  • the walls 10 of each upright may have a notch 35 in the lower part, to facilitate cleaning with a lance.
  • the uprights 1 and 2 can also have other sections than a U-shaped section having planar walls.
  • Figure 8 shows a variant of the upright of Figure 7, still having a substantially U-shaped section, but with a rounded front wall 7.
  • the wall 7 comprises two lips 18a, 18b which laterally delimit the slot 8. These lips 18a, 18b extend over the height of the slot 8, and extend over a short horizontal distance, parallel to the curtain 4, towards said curtain or away from said curtain.
  • Such lips can be advantageous in certain cases, to avoid damaging by localized friction the lateral parts which slide in the slots 8 of the lateral uprights. Their width is small, so that they can be easily cleaned.
  • FIG. 9 represents another variant of the section of FIG. 8, but with a wall 7 with a V section.
  • FIG. 10 represents another variant, in which the lateral uprights only have a V-shaped wall 7.
  • FIG. 11 represents a variant of FIG. 8, in which the flat lips 18a, 18b are replaced by rounded parts 19a, 19b.
  • the longitudinal lateral edges of the slot 8 can be provided with a protective coating, for example anti-friction, without departing from the scope of the present invention.
  • the lateral upright has an H section in which the wall 7 having the slot 8 extends between two wing walls 20 parallel to the curtain, the wing walls 20 extending at both towards the curtain 4 and towards the outside of the opening 5 from the front wall 7.
  • Such an upright with an H-section can possibly be formed by two U-shaped section profiles assembled, or by four assembled angles 30, 31, 32, 33, as shown in FIG. 12a.
  • the section of the lateral uprights 1, 2 has a U shape having a base 22 and two branches 21, but the slot 8 is formed in a wall 7 which represents one of the branches 21 of the U.
  • the sections of the uprights of FIGS. 7 to 13 can advantageously be used even when the door separates two air masses of identical or little different temperatures, but in places where strict hygiene must be maintained. In this case, it is not necessarily necessary to have a tight contact between the upright and the wall around the opening, and between the curtain and the upright, unless the door must prevent air passages to other reasons (sterile or dust-free room, overpressure room, ...)
  • the two angles 32, 33 closer to the curtain may optionally be made of plastic, and the other two angles 30, 31 of steel. This favors the sliding of the curtain, and we limit the damage caused by shocks from handling equipment on the uprights, while limiting heat exchange.
  • the uprights 1, 2 can also be produced in a single piece, as shown in FIG. 14, in which case the slot 8 is cut in the front wall 7.
  • the slot 8 can possibly open out at the top of the wall 7 for example if the curtain 4 is raised by winding, but said slot 8 may also not open into the upper part of the wall 7, as shown in Figure 14, for example in the case where the curtain 4 is raised by folding accordion.
  • the amount has two walls 10 parallel to the curtain 4: these walls 10 may optionally be connected to each other by spacers to strengthen the amount.
  • the lateral uprights 1, 2 can also be produced in two assembled parts 26, 27, which each delimit a longitudinal edge of the slot 8.
  • the two parts 26, 27 are section angles in L and are assembled by horizontal spacer plates or plates 22, 23, possibly associated with corner reinforcements 24.
  • the upper plate 23 may optionally include a cutout 28 in correspondence with the slot 8 to allow said slot 8 to open into upper part of the upright.
  • the plates 22, 23 can be welded, riveted, bolted, or fixed by any other means.
  • the plates 22, 23 can possibly be produced in two parts, as in FIG. 18.
  • FIG. 16 represents another variant of the invention, in which the curtain is raised by accordion folding as in FIGS. 3 and 4, but where the lateral uprights have a U shape with the branches of the U facing towards the inside the bay 5.
  • One of the branches of the U is in tight contact against the wall 9, and as can be seen in FIGS. 17 and 18, this branch of the U has over its entire height a vertical slot 36 which separates the upright into two sections 26, 27, as seen previously.
  • an applicator member 38 such as that shown in FIG. 18a, which has the shape of an elongated plastic body, mounted by an elastic articulation 39 on the profile 26.
  • an applicator member 38 is described in more detail in document EP-A-0 416 961 of the applicant or in the corresponding patent US-A-5 095 964.
  • the edge 4a of the curtain could possibly include flexible bands rubbing on the base of the U-shaped profile, such as those shown in FIG. 19, and described in document EP-A-0 194 194 of the applicant and in the corresponding American patent US -A-4 934 437.
  • the sections 26 and 27 comprise, in the upper part and in the lower part, plates made up of two plates which are not in direct contact with each other.
  • Figure 18 shows the lower plate 22, consisting of two plates 22a, 22b which lie on the ground and are separated from each other by a slot 22c.
  • the plate 22a is welded to the profile 27 over the entire profile of this profile and to the profile 26 over a short length of the profile of the profile 26.
  • the plate 22b is welded to the remaining length of the profile of the profile 26.
  • the plates 22a and 22b are cut substantially following the profile of the profiles 26 and 27, so as to have minimum dimensions of said plates to limit heat exchange.
  • the plate 22a constitutes a connecting member between the two profiles 26 and 27. Thanks to the slot 22c and the small width of the plate 22a, said plate constitutes a very limited thermal bridge between the profiles 26 and 27.
  • the plate 22b serves to stiffen the profile 26 and improve its seat on the ground.
  • Figures 19 and 20 show a variant of the amount of Figure 18, more especially intended for cases where said amount is located on one side of the wall 9 which is at a temperature T2 below 0 ° C, while the other side of wall 9 is at a temperature T1 greater than 0 ° C.
  • the interior of the U-shaped section of the upright is coated with an insulating lining 40, which aims in particular to avoid the formation of frost.
  • the lining 40 can advantageously be provided with heating means, such as for example resistive electrical wires 41.
  • heating means such as for example resistive electrical wires 41.
  • the lateral edges 4a of the curtain are provided with flexible insulating bands 42, for example of rubber, which rub on the base of the U-section of the upright: such bands insulators are described in more detail in document EP-A-0 194 194 of the applicant and in the corresponding American patent US-A-4,934,437.
  • the amount may not have an applicator member 38, the curtain 4 being in leaktight contact with the profile 27 by means of the flexible strips 42 and the insulating lining 40.
  • the lower plate 22 is covered with an insulating plate 43, with a slope towards the outside of the U, that is to say towards the opening 5, represented by the arrows 44 in FIG. 19 in order to drain condensation or defrost water, or water from cleaning inside the upright, out of the upright.
  • the plate 43 comprises heating means 45, for example electric heating resistors embedded in the plate 43 if the latter is made of plastic: this prevents the formation of frost on the plate 43.
