Description

Title of the invention: Device for emergency partitioning of a passage, such as a corridor or a door, and method of implementation artwork.

[0001] The present invention relates to a device for emergency partitioning of a passage, such as a corridor or a door, and to a method of implementation.

[0002] The partitioning device concerned by the invention is of the type comprising a frame, generally made up of a plurality of longitudinal elements, preferably profiled, on which a flexible tarpaulin-type sealing element is fixed.

[0003] In the present invention, the term "frame" means a rigid structure capable of holding the flexible closure element. However, it is not essential that the structure be closed on itself at all times. For example, the frame may thus comprise two vertical uprights, and an intermediate crosspiece in the inactivated position, and be closed on itself and further comprise a threshold bar in the activated position.

[0004] Document WO2015140301 describes a partitioning device used to close an opening, such as a door or a corridor, for example during works.

[0005] This device essentially comprises four telescopic profiles arranged, in use, on the right, left, top and bottom of the opening in order to constitute a closed frame for holding a sealing tarpaulin.

[0006] The profiles each comprise at least one groove arranged such that, in the position of use, the frame thus formed has at least a first frontal peripheral groove intended to allow the fixing of a tarpaulin. Advantageously, the profiles comprise a second groove arranged such that the frame formed has a second lateral peripheral groove directed towards the interior of the space delimited by the frame.

[0007] The sealing tarpaulin is fixed by pinching onto the frame by means of a seal inserted by force into the front peripheral groove. This tarpaulin advantageously comprises a zippered opening arranged to create a temporary opening allowing the passage of workers.

[0008] The profiles are rigidly connected, by clamping, at the four corners by rigid L-shaped corner pieces, then a flat spring is optionally fixed in the lateral peripheral groove. Due to the rigid fixing between a vertical profile (right or left), a rigid L-shaped junction piece and a horizontal profile (top or bottom), each spring exerts a thrust on each vertical and horizontal upright so that they bear against the sides and the ceiling of the opening.

[0009] Such a device is used in the context of work, for example the renovation of a premises of a building, which are known to be a source of dust, sometimes very volatile, which can invade and / or spread to other rooms of the building directly connected to the premises under construction.

[0010] The dust in question can sometimes have polluting or toxic properties, and are therefore dangerous, due to their particle size and / or their physicochemical nature.

[0011] For example, in the case of asbestos removal work from a building, there is a generation of dust or fine asbestos residues which must under no circumstances be released into the environment outside the premises under construction.

[0012] While the device described in document WO2015140301 ensures perfect sealing between the rooms by blocking the access doors, it requires installation lasting several tens of minutes by a professional. Furthermore, this installation is intended to last the entire duration of the work, so that the passage is partitioned off for this entire time before its complete dismantling.

[0013] However, there are applications for which it would be desirable to provide a fixed, but removable (i.e. not sealed or integrated into the masonry or the structure of the door) closure device for a passage such as a corridor or a door and having two positions: an inactivated position in which the system is retracted and the passage is free, and an activated position in which the frame is closed and obstructed by a tarpaulin (advantageously provided with a sealed sliding opening).

[0014] In particular, hospitals must be able to urgently partition certain passageways to enable the isolation of entire departments in the event of a health crisis, for example as part of nuclear, radiological, biological and chemical (NRBC) threat prevention plans.

[0015] However, adapting the layout of hospitals to these plans can be very expensive, very time-consuming and require work that requires access to the area concerned to be temporarily blocked while the work is being carried out.

[0016] For example, this work could consist of adding fire doors, but this requires a modification of the masonry and therefore difficult and costly work.

[0017] Furthermore, some countries have standards that may even prevent these arrangements. For example, corridors must meet dimensional standards that make them impossible to structurally modify to incorporate additional doors.

[0018] The present invention aims to propose a fixed, but removable solution, that is to say without modifying the masonry, to be changed or repaired, capable of closing a wide and high passage, which can be activated in an emergency, that is to say in a few minutes and by non-specialized personnel and not equipped with specific equipment such as a screwdriver or a stepladder.

[0019] Another objective of the invention is to provide an emergency sealing system capable of ensuring continuity of sealing of the tarpaulin fixing during activation.

[0020] Another objective of the invention is to provide an emergency closure system whose cover is protected in the inactivated position so as not to be damaged or receive dust.

[0021] Another object of the invention is to provide an emergency shutoff system which can easily be switched from the inactivated position to the activated position and vice versa, to enable personnel training in simulation exercises, or to enable inspection, without having to change the system.

[0022] To this end, the invention relates to a device for emergency partitioning of a passage of the type delimited by a floor, a ceiling and two walls, comprising, with reference to the position of use, a rigid frame formed of vertical and transverse longitudinal elements, each longitudinal element comprising a front face provided with at least one longitudinal groove for fixing an edge of a flexible closure element, such as a tarpaulin, device in which the frame comprises uprights intended to be fixed to the walls so that a lower end of the uprights is arranged at a determined distance from the floor, an upper crosspiece intended to be fixed to the ceiling and an intermediate crosspiece intended to be fixed between the ceiling and the floor, crosspieces which delimit: - an upper transom closed by a first flexible sealing element, and - a lower passage between the transom and the ground; the frame comprising a second closing element of which a first transverse edge is intended to be fixed to the intermediate crosspiece of the transom and a second transverse edge is intended to be fixed to a longitudinal element constituting a movable threshold bar capable of being fixed, by at least one reversible stop and fixing member, between the floor and the uprights of the frame to reversibly close the passage, a first and a second lateral edge of the second closing element each being fixed to an upright of the frame when the device is in the activated position

[0037] [Fig.l] illustrates an emergency partitioning device according to the invention, installed in a passage delimited by a floor S, a ceiling P and two walls M. In the remainder of the description, the passage described is a corridor.

[0038] The device according to the invention is described hereinafter with reference to this position of use by referring to the walls, the ceiling and the floor, but, of course, these structures of the passage nor the passage itself are not part of the invention. These references to the structures of the passage therefore serve only to describe the device according to the invention with reference to its position of use, whether it is in the inactivated position, that is to say in the standard position requiring no partitioning of the corridor, or in activated position in which the device partitions the corridor.

[0039] According to the invention, the device 100 comprises a rigid frame 101 formed of vertical and transverse longitudinal elements 101a.

[0040] Each longitudinal element 101a comprising a front face provided with at least one longitudinal groove 101b for fixing an edge of a flexible closure element B1-B2, such as a tarpaulin.

[0041] Preferably, the longitudinal elements are made up of metal profiles cut to the dimensions of the corridor.

[0042] Since the device according to the invention is intended to be permanently installed (even if it can be removed without having to modify the masonry), the profiles can be adjusted to the height of the walls and the width of the corridor by cutting the profiles during installation. Alternatively, the longitudinal elements can each be made up of at least two telescopic profiles allowing adjustment to the measurement.

[0043] Thus, the frame 101, once installed in the corridor, comprises uprights 102 fixed to the walls M in such a way that a lower end 102a of the uprights 102 is arranged at a determined distance dl from the ground.

[0044] The frame of the device according to the invention further comprises an upper crosspiece 103 intended to be fixed to the ceiling P and an intermediate crosspiece 104 intended to be fixed between the ceiling P and the floor S, at a determined height hl sufficient from the floor so that an adult of standard size can touch it without having to use a stepladder.

[0045] Typically, the determined height hl is between 2 meters and 2.2 meters. The determined height hl is advantageously that of standard doors, i.e. 2.04 meters in France.

[0046] The crosspieces 103 and 104 thus delimit an upper transom 110 which is closed by a first flexible closure element B1 during installation. As described below, the closure element B1 is fixed peripherally all around the transom by wedging the transverse and lateral edges of the flexible closure element in the groove of the longitudinal elements which constitute the structure, by means of a peripheral deformable joint.

[0047] The crosspiece 104 also delimits, between the transom and the ground, a lower passage 120.

[0048] In the inactivated position, this lower passage 120 is free.

[0049] According to the invention, the frame 101 also comprises a second closing element B2, the arrangement of which depends on the activated or inactivated position.

[0050] Generally speaking, the second closure element B2 has a first upper transverse edge B2a (with reference to the activated position, see [Fig.2]) which is fixed to the intermediate crosspiece 104 of the transom 110 and a second lower transverse edge B2b which is fixed to a longitudinal element 101a constituting a movable threshold bar 105 capable of being fixed, by at least one reversible stop and fixing member, between the floor S and the uprights 102 of the frame 101 to reversibly close the lower passage in the activated position (see [Fig.2]).

[0051] In [Fig. 1] which illustrates the inactivated position, the second closure element B2 is wound around the threshold bar 105 which is shown in dotted lines, and held suspended from the intermediate crosspiece 104 of the transom 110.

[0052] In the activated position, illustrated in [Fig.2], the second closure element B2 is fixed to the frame in a peripheral and sealed manner. In other words, a first and a second lateral edge of the second closure element B2 are each fixed to an upright of the frame when the device is in the activated position.

[0053] Thus, the frame 101 of the device 100 according to the invention comprises:

[0054] - two longitudinal wall elements 101a intended to be fixed each to a wall to form the amounts 102,

[0055] - a first longitudinal transverse element 101a intended to be fixed to the ceiling P to form the upper crosspiece 103 connecting the two uprights 102,

[0056] - a second transverse longitudinal element 101a intended to be fixed between the two uprights 102, at a determined height hl from the floor S to form an intermediate crosspiece 104 which delimits the impost 110 towards the ceiling, and the lower passage 120 towards the floor S; and

[0057] - a third longitudinal transverse element 101a forming the movable threshold bar 105, and fixed to the lower transverse edge B2b of the second closure element B2.

[0058] Preferably, the frame 101 of the device 100 according to the invention may further comprise, as illustrated in FIGS. 1 to 4, a fourth transverse longitudinal element 101a intended to be fixed under and in contact with the second transverse longitudinal element 101a to form together the intermediate crosspiece 104. In this case, the second lower transverse edge B2b of the second closing element B2 is fixed to the fourth transverse longitudinal element.

[0059] The intermediate crosspiece 104 therefore comprises either one or two longitudinal elements 101a. When it comprises only one longitudinal element, it is advantageously provided with two longitudinal grooves for fixing an edge of a tarpaulin: the first longitudinal groove receives the lower transverse edge B2b of the first closing element B1 of the transom 110, and the second longitudinal groove receives the upper transverse edge B2a of the second closing element B2.

[0060] Figures 1 and 2 illustrate a first embodiment of the device according to the invention, in which the uprights are in a single part, the intermediate crosspiece 104 (comprising one or two transverse longitudinal elements 101a) being fixed to the sides of the uprights 102.

[0061] An example of attachment is illustrated in an enlarged manner in [Fig.5], where one end of the intermediate crosspiece 104 is attached to the upright 102 by one, preferably two brackets 106.

[0062] This embodiment is simple since the uprights 102 are in a single part. The installation kit therefore contains few parts. However, the entire weight of the intermediate crosspiece 104, as well as the other forces that it exerts in use by the air pressure on the closing elements B1 and B2 rest solely on the brackets 106.

[0063] Figures 3 and 4 illustrate a second, more resistant embodiment, in which the uprights 102 are in two parts 102a-102b and the intermediate crosspiece 104 rests on the end of the lower segment 102a of each upright 102.

[0064] An example of attachment is illustrated in an enlarged manner in [Fig. 6]. In this embodiment, the longitudinal wall elements 101a are each in two parts, each part 102a-102b being spaced from the other by one end of the intermediate crosspiece 104.

[0065] As previously, the intermediate crosspiece 104 is held in position by brackets 106.

[0066] This embodiment is more resistant, because the lower segment 102a of the uprights supports the weight of the intermediate crosspiece as well as a large part of the other forces mentioned above.

[0067] In combination, in addition to the brackets 106, the device may include, but is not obligatory, spring blades 107 engaged above and below the intermediate crosspiece 104 and on the upright 102. These blades increase the rigidity of the assembly.

[0068] [Fig.7] illustrates a preferred embodiment, in which segments su upper 102b and lower 102a of the uprights 102 are fixed to the intermediate crosspiece 104 by means of T-shaped connecting pieces 108 comprising a front face provided with two curved longitudinal grooves 108a-108b, each capable of connecting a groove of a longitudinal wall element with a groove of a transverse longitudinal element.

[0069] More particularly, each T-shaped junction piece 108 comprises a front face provided with two curved longitudinal grooves 108a-108b, one 108a which is capable of connecting the lower segment groove 102a of the upright 102 with a lower groove 104a of the intermediate crosspiece 104 (which receives the second closing element B2), and one 108b which is capable of connecting the upper segment groove 102b of the upright 102 with an upper groove 104b of the intermediate crosspiece 104 (which receives the first closing element B1).

[0070] As before, it is possible, although not obligatory, to add a leaf spring above and below the intermediate crosspiece 104, connected to the segments of the upright 102.

[0071] The structure of the support of the partitioning device according to the invention being installed, the installer adds the first closing element B1 at the level of the transom 110. To do this, he inserts the edges of the closing element B1 into the grooves of the longitudinal elements delimiting the transom 110.

[0072] To this end, it is preferable to provide in the intermediate crosspiece 104, two parallel grooves: an upper groove 104b for the lower edge of the first closure element B1, and a lower groove 104a (with reference to gravity) at least for the upper transverse edge B2a of the second closure element B2.

[0073] Once the first closure element B1 is installed and the transom 110 is sealed, the installer inserts the upper transverse edge B2a of the second closure element B2 into the notch of the intermediate crosspiece 104, preferably the lower notch 104a.

[0074] It then fixes the upper transverse edge B2a of the second closure element B2 by forcibly inserting at least one seal J into the groove 104a. Preferably, before inserting the seal J, it is possible to provide staples such as those described in document EP2921611 under the terms “retaining means 34”.

[0075] Once the second closure element B2 is fixed to the intermediate crosspiece 104, it is stretched towards the ground and possibly cut to size by cutting it. Then, it inserts the lower edge of the second closure element B2 into the groove of the threshold bar and fixes it by forcing a seal J into the groove.

[0076] The installer can then wrap the second sealing element B2 around the threshold bar 105, going up towards the intermediate crosspiece 104.

[0077] Thus, in the inactivated position, the device comprises a closure element B2 wound around the threshold bar 105, and held suspended from the intermediate crosspiece 104 of the transom 110 by support elements 130.

[0078] These may be, as in figures 1 to 4, support strips 131.

[0079] However, such strips 131 do not protect the sealing element against dust or atmospheric elements.

[0080] In a preferred embodiment, the support elements 130 completely surround the second closure element B2 wound on itself and are washable. More preferably, the support elements 130 completely enclose the second closure element B2 wound on itself in an airtight and / or moisture-tight manner.

[0081] An exemplary embodiment is illustrated in Figures 8 to 10, in which the support elements 130 of the second closure element B2 are constituted by a sleeve 132 having a first free edge 132a and provided with a sealed closing means 133, for example a sealed sliding opening.

[0082] The sleeve further comprises a second free edge 132b for attachment to the crosspiece. intermediate 104 on either side of the first transverse edge of the second closure element B2. The sleeve 132 is shaped to receive and protect the second closure element B2 wound on itself around the threshold bar 105, in the inactivated position.

[0083] Advantageously, the sleeve is also shaped to house joints for fixing the second closure element B2 along the uprights 102 of the frame, in the activated position.

[0084] Figures 8, 9 and 10 illustrate three stages of activation of the emergency partitioning device according to the invention.

[0085] In [Fig.8], the device is in the inactivated position. The second closure element B2 is wound on itself around the threshold bar 105 and enclosed in the sleeve 132. It is thus supported and protected against the intermediate crosspiece of the transom, that is to say suspended from the intermediate crosspiece and held nearby, just below.

[0086] The underpass is therefore free and nothing prevents the passage of people or objects.

[0087] At the start of activation, illustrated in [Fig.8], the slide opening is open and the roller of the second closure element falls by gravity towards the ground.

[0088] This step is very quick, because given the height hl of the intermediate crosspiece the user does not need a stepladder to open the sleeve 132 or more generally to deactivate the support means 130. In addition, thanks to the weight of the threshold bar, the second closing element unrolls by itself.

[0089] It then remains to slide the threshold bar 105 between the floor S and the uprights 102 of the frame, that is to say under the lower ends of the uprights 102, as illustrated in [Fig. 10], to tension the second closing element B2.

[0090] The user then activates at least one reversible stop and fixing member, which will be described later, and fixes the lateral edges of the second closure element B2 against the uprights 102 by means of a seal inserted by force into the groove of the uprights 102.

[0091] The lower passage, located under the intermediate crosspiece, is then sealed off in a sealed manner by the second sealing element B2, which results in the partitioning of the corridor.

[0092] In a preferred embodiment, the seal fixing the upper edge of the second closure element B2 on the intermediate crosspiece 104 is continuous and extends laterally by a seal length sufficient to fix the lateral edges of the second closure element against each upright 102 in the activated position.

[0093] Thus, in the inactivated position, these lengths of seals on either side of the second closure element are supported in the support elements (and preferably protected when it is a 132 sleeve.

[0094] In this case, an upper transverse edge of the second closure element B2 is fixed in a groove of the transom by a fixing joint, and only an upper portion of each lateral edge of the second closure element B2 is fixed in a groove of an upright of the frame by a portion of fixing joint.

[0095] According to the invention, the device further comprises a retaining member preventing said portion of fixing seal held against each upright from forcibly coming out of the groove, for example when the second closure element is rolled up on itself to put it in the inactive position. The seal retaining member comprises, for example, a clamp, a screw or a pin, a spring-loaded pin, etc.

[0096] This makes it possible to maintain a lateral fixing start of the second closure element B2 against the uprights 102, which facilitates the finalization of the fixing to reach the activated position.

[0097] [Fig. 11] illustrates an exemplary embodiment of a reversible stop and fixing member intended to hold the threshold bar in the activated position, i.e. under the uprights and in contact with the ground.

[0098] The term "reversible stop and fixing member" means a fixing member forming both a position stop for the threshold bar in the partitioning position (foil-locking and holding in relative position with the uprights) and a reversible fixing means for this threshold bar in the partitioning position.

[0099] In this embodiment, each upright is provided with a reversible stop and fixing member 140 which comprises a stop plate 141 arranged at the lower end of the upright, against a face opposite the front face carrying the groove.

[0100] The stop plate 141 protrudes below the lower end of the upright which carries it, and which is arranged at the determined distance dl from the ground.

[0101] Thanks to this stop plate 141, the user can push the threshold bar as far as possible under the uprights, without having to take care of its positioning under the uprights. This stop also prevents the threshold bar from moving in its direction during the activated position (for example in the event of a gust of wind against the closing elements B1-B2.

[0102] The reversible stop and fixing member 140 further comprises a fixing member 142 for the threshold bar 105 under the lower end of each upright.

[0103] In the example illustrated in [Fig.l 1], the fixing member is a latch 142, but other structures can be chosen, such as for example a lug or a pin intended to enter an orifice of the threshold bar or vice versa, or even a male / female part intended to cooperate with a complementary female / male part carried by the uprights and / or the threshold bar.

[0104] In one possible embodiment, the reversible stop and fixing member 140 may further comprise a leaf spring 143 intended to be fixed between an upright 102 and the threshold bar 105.

[0105] These spring blades 143 are particularly useful at this location, i.e. on each side of the threshold bar 105, because they provide an additional vertical force which forces the threshold bar against the ground and reinforces the sealing of the partition.

[0106] Thus, in general, the partitioning device according to the invention functionally comprises two superimposed frames formed by the longitudinal elements 101a:

[0107] The first frame is closed in both the activated and deactivated positions to form a transom. It comprises two first longitudinal wall elements each intended to be fixed to a wall, a first transverse longitudinal element intended to be fixed transversely to the ceiling, and a second transverse longitudinal element intended to be fixed transversely between the two walls under the first wall elements, between the ceiling and the floor, to form an intermediate crosspiece.

[0108] The second frame is not closed in the inactivated position (the threshold bar is housed at the level of the intermediate crosspiece), and closed in the activated position, when the threshold bar is fixed under the uprights 102.

[0109] The partitioning device according to the invention is economical, easy to install and above all easy and quick to activate if necessary.

[0110] It can be dismantled if necessary, and is particularly, although not exclusively, suitable for the hospital sector in order to partition off part of the hospital very quickly.

[0111] The flexible sealing elements, in particular the second one, can easily be covered with useful visual information in the event of partitioning: warning, alternative evacuation plan, etc.

[0112] A device according to the invention is therefore particularly useful in this field, because its activation is rapid and allows personnel to devote themselves to other urgent tasks.

[0113] Furthermore, its ease of implementation allows anyone to activate it, without any particular skills, without tools, and without putting themselves in a risky position (for example balancing on a stepladder).

[0114] It can be adapted to any passage, thanks to the transom which allows the activatable part to be lowered to the height of an average person.

[0115] Furthermore, its maintenance is easy, because only the sleeve needs to be cleaned, the second sealing element being protected.

[0116] Emergency partitioning includes the following steps:

[0117] A) inactivation of the support means 130-131-132 of the second closure element B2 to release said second sealing element B2;

[0118] B) passing the ends of the threshold bar under the lower ends of the uprights until they are in abutment against the reversible abutment and fixing member;

[0119] C) activation of the reversible stop and fixing member to fix the threshold bar under the uprights;

[0120] D) insertion of the lateral edges of the second closure element B2 into the longitudinal grooves of the uprights; and

[0121] E) forcefully inserting a fixing seal so as to wedge the lateral edges in the longitudinal grooves of the uprights in a watertight manner.

[0122] According to embodiments not illustrated:

[0123] - the or each longitudinal groove of the longitudinal elements constituting the crosspiece intermediate is shaped to be able to receive an edge of at least one sealing element B1, B2 and a seal for force-fitting said edge in the longitudinal groove;

[0124] - the or each longitudinal groove of the longitudinal elements constituting the crosspiece intermediate is shaped to be able to receive an edge of a closure element B1, B2, all or part of the second free edge for fixing the sleeve to the intermediate crosspiece, and a seal for fixing the edge of the closure element Bl, B2 and the fixing strip in the longitudinal groove;

[0125] - the or each longitudinal groove of the longitudinal elements constituting the crosspiece intermediate is shaped to be able to receive only the second free edge for fixing the sleeve to the intermediate crosspiece and a seal for fixing the second free edge of the sleeve in the longitudinal groove.
