Definitions

  • the present invention relates to a device for closing a bay, for separating a room or for covering a swimming pool, silo, etc., comprising a curtain which can be wound around a winding axis having flexible side edges which are held in guide tracks during the winding and unwinding of the curtain.
  • the pressure acting substantially perpendicularly on one of its faces can be relatively high, in particular for curtains exposed to the wind.
  • Another non-negligible drawback for closing devices of a certain size is the mounting of the curtain, which generally requires laborious adjustment by a skilled workforce to ensure sliding with controlled friction at the edges of the curtain in its guide paths, uniform winding and unwinding and perfect flatness of the curtain in the unrolled position.
  • the object of the invention is essentially to remedy the aforementioned drawbacks and this in an extremely simple but very effective manner.
  • the aforementioned guide tracks are mounted on a support in an elastic manner and / or pivotally about an axis substantially parallel to their longitudinal axis, the aforementioned lateral edges continuing to be maintained in these tracks. guide during rotation and / or translation of the latter relative to the support.
  • the guide tracks are mounted by means of elastic means on the support, so as to be able to undergo a displacement in the direction of the curtain when a force is exerted on the latter.
  • the guide tracks are arranged on rods extending substantially vertically relative to the longitudinal axis of these guide tracks and mounted with a certain play in holes provided in a wall of the support, the aforementioned elastic means comprising a helical spring threaded on the aforementioned rod on the opposite side of this wall with respect to the guide tracks and pressing against this wall.
  • Figure 1 is an elevational view, partially broken, of a device according to a first embodiment of the invention.
  • Figure 2 is, on a larger scale, a section along line II-II of Figure 1.
  • Figure 3 is a schematic representation of a horizontal section of this same embodiment, showing the position of the device under the action of a horizontal force applied to the curtain.
  • Figure 4 is a cross section, similar to that of Figure 2, of a second embodiment of the device according to the invention.
  • Figure 5 is also a cross section similar to that of Figure 2 of a third embodiment of the device according to the invention.
  • the embodiment of the closure device according to the invention comprises a curtain 1 which can be wound around a winding axis (not shown) and is intended for the closure of a bay, such as a garage entrance, workshop, shed, and also as a partition wall of a room, or to cover a swimming pool, a silo, etc.
  • a bay such as a garage entrance, workshop, shed, and also as a partition wall of a room, or to cover a swimming pool, a silo, etc.
  • This curtain 1 has flexible lateral edges 2, which project from the plane of the curtain and which are kept sliding in guide tracks 3, provided laterally on either side of the opening to be closed eg
  • This device is essentially characterized in that the guide tracks 3 are mounted on a support 4, laterally delimiting the bay, in an elastic manner and / or pivoting around an axis substantially parallel to the longitudinal axis of these guideways, and this in such a way that the lateral edges 2 of the curtain can continue to be maintained in these guideways when the latter move relative to the support 4.
  • the set of parts of the guide path which hold the edge of the curtain which is mounted resiliently and / or pivotally on the support 4. Means could however be provided to allow the release of these lateral edges 2 from their guide paths when the traction force exerted by the curtain on them exceeds a certain value.
  • the guide tracks 3 are mounted by means of elastic means, forms of helical springs 5, on the support 4, so as to be able to thus undergo displacement in the direction of the curtain 1 when a force, illustrated by the arrow 6 in FIG. 3, is applied thereto.
  • the guide tracks 3 are arranged on rods 7 extending vertically relative to the longitudinal axis of the latter and mounted with a certain clearance in holes 8 formed in the wall of the support 4, the latter being, in this form of construction, consisting of a metal box.
  • the helical springs 5 are threaded on the rods 7 inside the box, pressing on the inside wall of the latter, on the opposite side of its wall on which the guide path 3 is mounted.
  • the aforementioned rods 7 have a threaded free end 9 and are each mounted coaxially in a sleeve 10 passing with a certain clearance through the holes 8 formed in the support box 4, this sleeve being immobilized relative to the guide path 3 by a nut 11 screwed onto the threaded free end 9 of the rods 7.
  • the springs 5, which are threaded on the sleeve 10 are held with a certain compression between the nut 11 and the inner face of the wall of the support box on which the guide path 3 is mounted. In this way, the springs exert a certain traction on the guide path 3 in a direction perpendicular to the longitudinal axis of the latter.
  • a flexible sealing strip 12 for example made of rubber or plastic, is provided between the guide path 3 and the support box 4.
  • One of the lateral longitudinal edges 13 of the sealing strip 12 has orifices which are crossed by the rods 7.
  • the latter are fixed at regular distances from one another on the back 14 of the guide tracks 3, as shown clearly in FIG. 1.
  • This edge 13 is held against the back 14 of the guide path 3 via the free end of the sleeves 10 directed towards this back, which is applied around the abovementioned orifices against this edge 13.
  • the sealing strip 12 forms a loop 15 between the guide path 3 and the support box 4.
  • the rods 7 freely cross the branch 16 of the loop 15 located on the side of the support box 4, so that it can move freely on the sleeve 10 threaded on the rod 7.
  • the other branch 17 has the free edge 13 and is fixed against the back 14 of the guide path by the free end of the sleeve 10, as already described above.
  • the projecting lateral edges 2 of the curtain 1 are formed by a succession of small juxtaposed identical blocks 2 ′, preferably made of a material hard plastic, located in the extension of each other and close to each other, being connected in a flexible way between them, for example like the blocks of a zipper known per se.
  • these blocks can be as close as possible to each other as long as the lateral edges 2 remain flexible enough to allow the curtain to be wound around an axis.
  • the guide tracks 3 each have two longitudinal edges 18 and 19 located on either side of the curtain 1 and directed towards each other in a direction substantially perpendicular to the curtain.
  • these guide paths 3 surround the projecting edge 2 of the curtain 1.
  • These two longitudinal edges 18 and 19, which therefore retain the protruding edge 2 of the curtain 1 in the guide tracks, are part of two separate sections of somewhat elastic material 20 and 21, which each have a cross section having a shape substantially Z-shaped.
  • One of the two wings of these profiles 20 and 21 forms the abovementioned longitudinal edge, respectively 18 and 19, the other wing 22, respectively 23, forming the base of these profiles, which is held in a rigid metal profile.
  • the two Z-shaped profiles 20 and 21 are held in the U-shaped profile 24 by an intermediate rod 27 clamped in the latter between the bases of these two profiles 20 and 21 and an intermediate rod 31 on either side of these profiles and the adjacent wing of the U-shaped profile.
  • a support profile 28 also in U-shaped, the wings of which have flanges facing one towards the other.
  • Contacts 32 can for example be arranged between the guide path 3 and the support 4 in order to detect the moment when the protruding edge 2 of the curtain 1 is released from the guide path and / or when the force 6 exerted on the curtain 1 exceeds a specified limit. These contacts 32 are then preferably connected to an alarm circuit for, for example, putting out of service and blocking the curtain in its winding or unwinding movement, or simply to activate a warning device. These contacts could also be provided inside the box and cooperate with the rods 7.
  • means can advantageously be provided for intercepting the force 6 acting on the curtain when it reaches a certain limit, without the projecting edge 2 being released from its guide paths 3.
  • the projecting edge 2 could for example be fixed to the curtain by means of low resistance extending between the curtain and its projecting edges 2.
  • These means could for example be formed by a flange and pins having a resistance calculated so that these pins can break as soon as the force 6 reaches a predetermined limit. It would also be possible to provide, between the projecting edge 2 and the plane of the curtain, a zone of low resistance which can yield when the aforementioned force acting on the plane of the curtain reaches a certain level which is less than the force necessary to release the edge protruding 2 of its guide path.
  • the embodiment of the device according to the invention shown in Figure 4 differs essentially from that of Figure 2 in that the elastic means are constituted by elements of substantially elastic foam 5, such as polyurethane foam or latex. These elements 5 extend over the entire length of the guide path 3 and thus make it possible to seal between the latter and the support 4 on which it is mounted, without the need for an additional strip. sealing, as in the previous embodiment.
  • These foam elements 5 consist of bars of rectangular section and are arranged in a U-shaped profile 34 fixed by welding against the outer face of the support box 4. The lateral wings of this profile 34 have flanges 35 directed one towards the other against which one of the faces 38 of the foam elements 5 is applied.
  • the Z profiles 20 and 21 are fixed over their entire length in a removable manner between two identical plates 37, one of the longitudinal edges of which has the appearance of a hook (25) and holds the profiles 20 and 21 in place, the opposite longitudinal edge being provided with support legs 36 applying against the face 39 of the foam elements 5 opposite to that resting against the flanges 35 of the profile 34.
  • An intermediate plate 27 extends between the two plates 35 and the bases of the sections 20 and 21 and determines the distance separating the latter from each other.
  • the hook-shaped edges 25 are applied in an elastically adjustable manner against the profiles 20 and 21 so as to be able to thus control the force acting by the latter on the edges 2 of the curtain 1, particularly the force which is necessary for clear the edges 2 of the guide path 3.
  • the free edges 40 of the hooks 25 are slightly inclined by applying elastically against the profiles 20 and 21 and a bolt passing through the plates 37 and the intermediate plate 31 allows, by means of a nut 42 screwed on this bolt 41, to adjust the pressure exerted by these free edges 40 on the sections 20 and 21.
  • the embodiment of the device according to the invention as shown in FIG. 5 differs essentially from that of FIG. 4 by the fact that the elastic means consist of two bands of elastic material 5, such as rubber or a plastic elastomer, which are subjected to a tensile force, while, in the embodiment according to FIG. 4, the foam strips 5 are subjected to a compressive force.
  • One of the lateral edges of these strips 5 has a bead 43 held in a gutter 44 of the plates 37 applied against the intermediate plate 31.
  • the other lateral edge of these strips is folded against the outside face of the support box 4 and is held against the latter by regularly spaced 45 bolts.
  • stop means making it possible to limit the displacement of the guide tracks 3 in the direction of the curtain 1 when a force 6 is exerted on the latter.
  • the stop is automatically obtained when all the turns of the spring are applied against each other. If the elastic means are formed of foam elements, the stop is obtained when these elements are fully compressed. If elastic bands are used, which are therefore subjected to traction, it could be important to incorporate therein an armature making it possible to limit the elongation of the band in the direction of traction.
  • the curtain is constantly under a controlled horizontal tension and expansions or shrinkages of the curtain which could occur following temperature fluctuations will be automatically compensated by the elastic means. This will also be the case for variations of distance between the guide paths on either side of the curtain, eg if the latter are not perfectly parallel.
  • the guide tracks can pivot around an axis parallel to their longitudinal axis, the traction exerted by the curtain 1, via the edges 2, will always be distributed symmetrically on the two sections 20 and 21, in particular on the two flanges 18 and 19 respectively of the latter, and this always in a direction substantially parallel to the core 34 of these two sections 20 and 21.
  • the guide path 3 could be mounted on the support 4 by means of a hinge or a series of successive hinges, the axis of rotation of which is parallel to the axis of this guide path.
  • these paths guide could be mounted on their supports so as to be able to undergo only a translation along the plane of the curtain in the closed position, the elastic means would then not allow the pivoting of the guide path.
  • the edge 2 of the curtain 1 could be provided with spaced guide means, such as rollers or pads extending at a certain distance from each other on the edge of the curtain. It would therefore not be a substantially continuous projecting edge.
  • the curtain 1 consists of a tarpaulin and has at least one substantially elastic zone 50, formed for example by a strip of elastic material shown diagrammatically in FIG. 1, s' extending over the entire length of the curtain 1, in the direction of its lateral edges.
  • This area 50 can in principle be located anywhere on the curtain, but for reasons of symmetry, eg it will preferably be near each of its lateral edges 2 or possibly in the middle. However, a single elastic zone could also be provided near one of the two lateral edges 2. In a variant, the entire curtain could be made of a substantially elastic material.
  • the guide tracks 3 could be pivotally mounted or be fixed on the support 4. We could even combine these latter embodiments with those where the guide tracks 3 are resiliently mounted on the support 4.
  • the curtain preferably consists of a fully flexible continuous sheet, in contrast to the curtains which comprise at regular distances horizontal bars which are slightly flexible or not, which provide lateral guidance of the curtain.
