Definitions

• the present invention relates to a door with vertical opening having a flexible curtain capable of occupying a closed position or an opening position by folding up to a desired height having a curtain comprising two flexible screens defining an air mattress making thermal or sound insulation.
• These doors thanks to the additional thermal and sound insulation they provide compared to single screen doors, are particularly suitable for closing building bays giving onto the outside, in particular to delimit an area subject to wind, bad weather and large temperature differences.
• These doors can also be used to delimit two zones, one of which has a high noise level.
• the structure of these doors can consist of horizontal bars held together by cables or by straps. Horizontal strips of flexible fabric, generally PVC, are attached to these bars to form on each side thereof two screens which delimit an air mattress.
• the invention aims to provide a double screen door delimiting an air mattress, while being simple to implement, while having a great seal.
• this door comprises two lateral uprights, a transverse box connecting the upper ends of the two uprights and a movable curtain between a closed position in which it closes the opening formed by the uprights and the box and a position of opening in which it is folded under the box.
• the door comprises a curtain made up of two parallel screens delimiting an air mattress, suspended at the level of the upper zone of the uprights, the curtain comprising: - at least one lifting strap connecting the lower part of the curtain to a shaft mounted at the level of the box, - and at least one transverse stiffening means attached to each of the screens, the lateral edges of each screen coming into contact with the uprights to form a sealed surface surface contact.
• the basic idea underlying the invention consists, in a double screen curtain, of placing stiffening bars in sleeves formed in each screen so that the inner face of each of the two outer faces of the double screen is flat and is always stretched in the closed position so that, coming against a slide formed in the vertical uprights, a surface contact is formed which provides total sealing of the air mattress formed between the two screens.
• the curtain moreover, can be entirely factory made then simply mounted on the final site.
• the sleeves of each of the screens are opposite two by two.
• at least one pair of two stiffening bars, engaged in two sleeves facing each other has at least a spacer connecting said bars.
• the spacer has an opening for the passage of the lifting strap.
• at least two pairs of braced stiffening bars alternate with at least one pair of unbraced stiffening bars, so that, in the raised position of the curtain, alternating folding folds are formed symmetrically with respect to the plane door opening.
• the lower part of the curtain formed by the junction fold of the two screens, receives a flexible element constituted by a flexible sheath containing a flexible material.
• the flexible element is constituted by a flexible bar comprising a foam-sheathed spring.
• the ends of each stiffening bar are provided with guide elements relative to each of the uprights.
• the stiffening bars have a flexibility allowing to absorb an abnormal shock to go out, to disengage or to disapply from the slides without undergoing permanent deformation so that the curtain is not damaged during a collision for example with a vehicle.
• the flexible bar retained in the junction fold of the two screens, the lower pair of braced bars and the pair of consecutive non-braced bars are at distances such that, in the raised position of the curtain, the flexible bar protrudes from the folds formed by each screen folded so that in the event of a collision with the curtain, contact is made with the flexible bar rather than with a stiffening bar.
• each screen is made up of a multilayer complex.
• each screen has, at the same height, at least one transverse panel made of transparent material.
• each screen is provided with at least one shape memory bender which can form a fold towards the outside of the curtain in the folded position thereof.
• the curtain according to one possibility, it is formed in a single element of flexible material and then is folded back on itself to form two screens.
• each screen comprises at least two panels of transverse flexible material connected by a sheath.
• the ends of each stiffening bar of a pair of non-braced bars are provided with a guide tip having a flat part oriented in the plane of the screen in which the bar is located.
• a spacer connects the ends of a pair of bars and supports a roller capable of engaging between two slides formed in each of the vertical uprights.
• provision may be made for filling nozzles to be engaged at the end of each of the bars to avoid the formation of folds.
• a cable is engaged in at least one sleeve, the ends of which are guided relative to the vertical uprights.
• FIG 2 is a section of the curtain constituting the door;
• Figure 3 and 4 is a sectional view of the door at an amount thereof.
• the door comprises two lateral uprights 2 connected at their upper ends by a box 3. Box 3 can also be called crosspiece.
• Box 3 can also be called crosspiece.
• the door comprises a flexible curtain 10 which can be folded up in the upper part of the door, that is to say under the box 3, to allow the passage of people or of vehicles through it.
• the curtain 10 consists of two parallel screens 1 1 a, 1 1 b. These two screens 1 1 a, 1 1 b define an air mattress which gives the door great sound and thermal insulation.
• each screen 1 1 1 a, 1 1 b consists of panels 12 of flexible material; it can be transparent or opaque PVC. As can be seen in FIG. 2 between two consecutive panels 12, two superimposed strips 13 are welded to each of the panels 12 and thus form a sheath 15.
• each of the screens 1 1 a, 1 1 b has four equidistant sleeves; the number of sleeves 15 depends of course on the height of the door.
• a stiffening bar 16 is engaged inside each sleeve 15. This stiffening bar 16 is made of flexible material which can be a pultruded composite.
• each screen 1 1 The sleeves 15 of each screen 1 1 are arranged such that the stiffening bars 16 are two by two placed at the same height to form a pair of stiffening bars. It should also be noted that certain stiffening bars 16 of the same pair are connected by two spacers 18. The assembly formed by these two braced bars 16 thus has a high inertia module. The pairs of braced and non-braced bars 16 are alternated. The raising of the curtain is controlled by two lifting straps 20. One end of each strap is connected to a shaft 19 fixed in the box 3 of the door and the other end of which is connected to the pair of the lowest braced stiffening bars.
• the spacers 18 connecting the stiffening bars located above the lowest braced pair are provided with an opening 21 allowing the passage of a lifting strap 20.
• the curtain 10 is provided at the junction fold of the two screens 1 1 a, 1 1 b with a flexible bar 22 which may consist of a spring sheathed in absorbent foam.
• Figures 3 and 4 illustrate the manner in which the guidance of the end of the stiffening bars can be done according to an embodiment of the invention relative to the side uprights 2.
• the uprights 2 themselves have two parallel slides 24 and 25. Referring first to Figure 3, we see that the guide tips 28 are fitted into each of the bars 16 of stiffening.
• end pieces 28 have a cylindrical part 29 whose diameter corresponds to the internal diameter of the stiffening bars, which allows the engagement of the end pieces in the stiffening bars.
• the cylindrical part of the endpiece is extended by a frustoconical part 30 which itself is extended into a flat part 31.
• the end pieces 28 are engaged in the stiffening bars with an orientation such that the flat part 31 is in the plane of each screen.
• Figure 4 shows in section the guide of a pair of stiffening bars connected by spacers. At the end of the two stiffening bars, a spacer 33 secures the latter.
• the strip 13 constituting the inner wall of the sleeve 15 has a cutout allowing the spacer 33 to assume the junction with the stiffening bars 16.
• the spacer 33 supports a roller 32 whose diameter is slightly less than the distance separating the slides 24 and 25.
• filling tips 34 are engaged in the ends of the stiffening bars 16 which prevent the formation of folds at the end of the bars 16.
• the door behaves as follows: When the curtain 10 is in the closed position, the interior faces of each screen 1 1 a 1 1 b are applied against the rails of the uprights as can be seen in Figure 3 or in Figure 4 thanks in particular to the guide elements , namely end piece 28 and roller 32.
• each screen could be formed by an overlapping area of the panels and by two parallel weld lines or by a strip welded directly to the outer face of a panel. It is also possible to make the curtain in a single element of flexible material and then fold it to form two screens. It is conceivable to implement the invention in an embodiment in which the ends of the stiffening bars are directly applied against the uprights or against flexible or rigid slides arranged in the latter.
