Description

The present invention relates to a telescopic upright intended to be positioned in an opening, of the door or window opening type delimited by a frame or of a type delimited by adjacent walls in order to form a telescopic upright. amount of a frame arranged to receive a closure member, for example a sheet, said telescopic post comprising: a first outer profile comprising a front wall, a back wall and two connecting walls, each of the walls having an inner face and an outer face, said first profile having a portion of light forming a cavity of a first substantially U-shaped groove, said front wall having a longitudinal orifice forming an opening of said first groove, the adjacent portions of which are formed by two internal lips each extending from one of the connecting walls, and a second internal profile comprising comprising a front wall, a back wall and two connecting walls, each of the walls having an inner face and an outer face, said outer face of one of said connecting walls of said second profile being provided with a broom at least partially on its length, said second section having a portion of light forming a cavity of a second substantially U-shaped groove, said front wall having a longitudinal opening forming an opening of said second groove, the adjacent portions of which are formed by two internal lips; extending each of one of the connecting walls, said first and second sections being concentric and arranged to cooperate by sliding. Such an amount, but not including a broom, is known from the state of the art, including telescopic rods placed between two side walls, for example for the establishment of curtains. Such a telescopic upright is based on two concentric sections that should be slid relative to each other to extend and increase the length of the rod. Unfortunately, the sliding of such profiles into one another is very often hampered by blockages. Indeed, if the two profiles are not perfectly maintained in the same axis during their sliding, that is to say, as soon as one of the two profiles has a slight inclination relative to the other, forces of friction and friction appear and make particularly difficult an extension of the telescopic post. These problems of friction and blocking are further accentuated by the inevitable and essential presence of play between the two profiles. It is indeed necessary, to be able to slide the two sections, a slight spacing of the order of a millimeter is provided between them. However, however small this spacing, it still favors an offset between the two sections, which induces friction forces or blocking of the telescopic post. Another telescopic upright, this time comprising a brush on an internal profile, is known from document FR2961549. This document describes a telescopic post intended to be placed in a frame and which comprises two concentric sections cooperating by sliding. More particularly, a first external profile is arranged to receive a second internal profile, which has on the outer face of one of its walls a broom provided to prevent the passage of dust via the gap between the inner profile and an edge of the frame. This document therefore includes a telescopic device similar to that described above with the difference that a broom is present. Therefore, the same blocking problems related to the presence of friction and friction forces are also encountered with such amount. Moreover, the presence of a broom even increases the friction forces since it constitutes a thickness responsible for greater play between the two sections. In addition, this additional thickness increases the pressure forces exerted by the second inner section on the first outer section, which further accentuates the friction and friction forces responsible for frequent blockages. The presence of such a thickness formed by the blade may further lead to a deformation of the first outer profile because of the pressure forces essentially exerted by the blade having a small surface which bears against said first outer profile. However, since the pressure force is defined by the formula P = FIS and since the surface of the blade is relatively small compared to the surface of the first profile, the pressure force applied to the latter is all the more important. The object of the invention is to overcome the drawbacks of the state of the art by providing a telescopic post which does not suffer from blocking problems, being little subject to friction and friction forces and not being subject to problems. problems of deformation of the profiles. To solve these problems, there is provided according to the invention, a telescopic upright as indicated at the beginning, characterized in that said first external section comprises on said inner face of a wall facing one of said connecting walls of said internal section. a gutter 20 formed in a wall thickness and arranged to receive said brush located on said second inner profile when said first and second profiles are arranged to cooperate by sliding. The presence of such a gutter is particularly advantageous since it allows the broom to be housed therein at least partially so that it no longer constitutes a thickness responsible for a considerable clearance between the two sections. Furthermore, this groove forms a guide element during the sliding of the second inner profile in the first outer profile, which also contributes to minimizing the clearance between the profiles but also to maintain these last 30 in the same axis to avoid any additional appearance of frictional and / or frictional forces responsible for blocking as described above. In addition, since the blade is housed at least partially in this channel, the second section can bear against said first section in close contact along two side portions of the inner face of the first section, these two side portions being located on both sides of the gutter. Such close contact between the two sections, on either side of the gutter constituting a guide element, makes it possible to maintain permanently, that is to say, even when sliding the profiles one with respect to the Another, a common axis for the two sections that are not positioned from then more across from each other and therefore do not lock. Advantageously, said first outer section of the telescopic post according to the invention further comprises a third U-shaped groove comprising two shoulders formed in side walls of said third groove towards the opening of said third groove and forming two longitudinal rails whose apertures communicate with another portion of light of said first outer profile, said third groove being located on a connecting wall opposite to that comprising said channel and being arranged to receive a locking means. Advantageously, said locking means is a screw-nut system. Preferably, according to the invention, said second internal section comprises two lips arranged to bear respectively in said longitudinal rails formed by said shoulders of said third U-shaped groove present on said first outer profile, when said first and second profiles are arranged to cooperate by sliding.

The U-shaped groove thus has two shoulders which form two longitudinal rails, and which allow two lips of the second section to be supported by inserting into said rails formed by these shoulders. Apart from the fact that such a positioning makes it possible to orient the two profiles correctly with respect to each other, it also makes it possible, by means of a screw-nut locking means, to block the telescopic upright by a given position. Indeed, the screw-nut system allows, by clamping, to compress the lips of the second profile in the longitudinal rails formed by the shoulders so that the two profiles are momentarily secured to one another in a predetermined position. More particularly, a nut is inserted into the third U-shaped groove and a screw is engaged in this nut. When tightening this screw, the nut is brought into abutment against the shoulders forming the two longitudinal rails so that pressure is exerted on the lips of the second section which are located in the longitudinal rails formed by the shoulders. Advantageously, according to the invention, said first outer profile comprises a bead and said second inner profile comprises at least one longitudinal nesting cavity arranged to receive said bead or vice versa, when said first and second sections are placed by sliding concentrically. Whether the bead is located on the first section or on the second section and therefore a longitudinal nesting cavity is provided to receive the bead on the second or on the first section provides an additional guide to position and optimally moving longitudinally the second inner profile into the first outer profile. Moreover, the presence of this bead along the length of a profile makes it possible, by placing in a longitudinal nesting cavity as provided by the invention on the other profile, to stiffen the telescopic upright, which allows avoid deformations of the latter, for example when sliding profiles. Preferably, according to the present invention, said blade comprises a rear mounting portion and is removably mounted by positioning the dorsal portion in a recess formed in a wall thickness on an inner face of one of the walls of said second section. internal. This is particularly advantageous since the broom is the fastest wear element relative to the other elements of the telescopic post. According to the invention, the blade can be easily removed and replaced, which allows to reuse the profiles many times. Advantageously, said first and / or said second section comprises a plurality of reinforcing walls connecting a first pair of their side walls.

Equally advantageous, according to the invention, said first and / or said second profile comprises a plurality of reinforcing walls connecting a second pair of their side walls. In order to reinforce the profiles and so that they have adequate strength, it is in fact provided, according to the invention, reinforcing walls connect in pairs the side walls of each of the profiles to give them optimum rigidity. Preferably, according to the invention, said second groove of said second internal profile and said first groove of said first external profile form, when said first and second profiles are arranged to cooperate by sliding, a groove of at least partial superposition of two profiles comprising an orifice. longitudinal formed by the at least partial alignment of said longitudinal orifice present on the front wall of said first profile and said longitudinal orifice present on the front wall of said second profile, said at least partial superposition groove of two profiles being arranged to receive and maintain at less partially a substantially peripheral portion of a closure member, for example an edge of a sheet, with a seal. By the term "slidably cooperating" is meant, in the sense of the present invention, the covering of an element at least partially by another or by at least partial insertion of one element concentrically by another. In this case, in this case, the second substantially U-shaped groove of the inner profile slides at least partially in the first substantially U-shaped groove of the outer profile and is therefore at least partially covered by the latter. According to the invention, it is understood that each of the substantially U-shaped grooves of each of the first and second profiles is also arranged to receive and maintain at least partially a substantially peripheral portion of a closure member, for example a edge of a sheet with a seal, a nesting of the first and second grooves is not essential for a restraint of a closure element takes place. Each groove (first, second or at least partial superposition groove of two sections) makes it possible to introduce there at least partially a substantially peripheral part of a closure element, such as for example the edge or edge of a tarpaulin. plastic, it is possible to block and maintain in this groove for example via a seal which is thus housed in the groove. The latter can be retained in said groove, for example by two internal lips located at the upper part of said groove. Other embodiments of the telescopic post according to the invention are indicated in the appended claims. The present invention also relates to a telescopic system comprising at least four telescopic uprights forming a frame arranged to be positioned in an opening, such as a door or window opening defined by a door frame or of a type delimited by adjacent walls, said system telescopic means being further arranged to receive a closure element, for example a tarpaulin, and further comprising at least four connecting pieces, in particular four corner pieces, in which two perpendicular adjacent uprights are nested. The telescopic system then forms a closure system of the opening. Advantageously, said two perpendicular adjacent uprights nested in a junction piece, in particular in a corner piece, are further connected by a compensation means, for example by a flat spring. For the purposes of the invention, the term "encased" means that an element is covered and retained at least partially by another or by at least partial insertion of one element concentrically with respect to another. In this case, for example, each amount is substantially encased in a portion of the joining piece so that the amounts are non-parallel, in particular substantially perpendicular.

Advantageously, said shutter system of an opening, of the door or window opening type delimited by a door frame or of a type delimited by adjacent walls, comprises: a shutter element, for example a tarpaulin, arranged to cover said opening, - a frame, composed of at least four sections each forming an amount of said frame, each section comprising a front wall, a back wall and two connecting walls and having a portion of light forming a cavity of a groove substantially U-shaped, said frame being adapted to be positioned within said opening and having a first fastening means, and - a second fastening means, said first and second fastening means being adapted to cooperate together so as to ensuring the maintenance of said shutter member on said frame and to be dissociable so as to allow the removal of said shutter member on the frame, the said first fixing means being an opening defined by a longitudinal orifice present on said front wall of each profile forming an opening of said groove, the adjacent portions of said opening being formed by two internal lips each extending from one of the walls of said connection, said groove of said section being intended to accommodate a substantially peripheral portion of the closure member passing through said opening, said second fixing means being formed of at least one peripheral seal arranged to be held in a manner adjusted by each inner lip said opening of said groove in which said substantially peripheral portion of said closure means is housed and fixed. The closure system comprises at least one means for retaining said closure means having a first predetermined profile complementary to a second predetermined profile of said groove, said at least one retaining means being arranged to be housed, at least partially, in said groove of said profile, between said substantially peripheral portion of the closure member and said seal, superimposed above said substantially peripheral portion of said closure member so as to retain it on said frame and so as to accommodating said at least one peripheral seal having a third predetermined profile arranged to cooperate with said first predetermined profile of said retaining means. In this way, when the shutter system is being positioned and the frame is placed in an opening, it is necessary to position the shutter member. According to one embodiment, this means that the distributor must hold the shutter element, align it along a profile forming a basal amount of the frame and insert the basal part of said shutter element in the profile light basal and substantially peripheral forming a groove. Then, it places in this groove the retaining means which will maintain at least a substantially peripheral portion of the closure member in the groove time to place the peripheral seal. Then, the distributor raises the shutter member in the vertical position and then positions for example a series of retaining means in the profiles forming the side-vertical uprights of the frame over the shutter member rectified in the position of shutter to cover the opening. Finally, it places the retaining means over at least a peripheral upper part of the closure element, without any difficulty since the lower part of the latter is securely stowed in said groove as at least a peripheral portion lateral. He can then take the time to comfortably and easily position the longitudinal joints in the lateral and upper grooves and thus ensure the total hermeticity of the system. Of course, in the context of the present invention, the retaining means may have a length much less than the width of the opening. In this case, the distributor can position several retaining means at regular intervals. On the other hand, if the retaining element has a great length, the distributor can position much less. According to another embodiment, the placement of the shutter member on the frame can be achieved by aligning it with the profile forming the upper amount of the frame and placing at least a substantially upper peripheral portion of the frame element. shutter in the cavity of the groove defined by a light portion of the profile forming the upper amount. Then, it is appropriate to place retaining means which will maintain the substantially peripheral portion of the closure member in the lumen of a profile forming a groove, said profile forming a higher amount of said frame the time to place a peripheral seal. Then, the distributor can let the shutter member deploy from top to bottom under the action of its weight without seeing its substantially upper peripheral portion unhook. The closure element is indeed integrally connected to the upper amount of the frame by the presence of the retaining means retaining the substantially peripheral upper portion of the closure element in the groove of the profile forming the upper amount. The distributor will then position a series of retaining means in the profiles forming the lateral-vertical uprights of the frame over the closed obturating element in the closed position to cover the opening. Finally, it will place the retaining means over at least a substantially peripheral basal portion of the closure element, without any difficulty as soon as the upper part and the lateral peripheral parts of the closure element are securely fastened. in the throat. The operator can then take the time to comfortably and easily position the longitudinal joints in the lateral and basal grooves and thus ensure the total hermeticity of the system. In addition, the presence of retaining means positioned between the closure member and the seal, but all, housed in the groove drastically reduces the impact of the friction coefficients of the seals and the closure member which can then take any value, leaving free choice of the nature of materials forming said peripheral seal and the sealing member. Similarly, whether the materials are rather elastic or rigid, the impact on the assembly will also be greatly reduced.

In addition, said closure member is optionally provided with a zipper. The presence of this slide then facilitates the passage to a building site by allowing a temporary opening of the shutter system without systematically having to dismount and reassemble the frame.

Preferably, said at least one peripheral seal is made of a flexible material. Advantageously, said at least one peripheral seal comprises a plurality of longitudinal joints.

Preferably, said at least one retaining means is made of a rigid material. Advantageously, said at least one retaining means comprises a plurality of retaining means. Preferably, at least one of said uprights of the frame 10 comprises a first external section and a second internal section arranged to cooperate by sliding to form a telescopic upright comprising: a first external section comprising a front wall, a back wall and two connecting walls , each of the walls having an inner face and an outer face, said first profile having a portion of light forming a cavity of a first substantially U-shaped groove, said front wall having a longitudinal orifice forming an opening of said first groove whose adjacent parts are formed by two internal lips each extending one of the connecting walls, and a second inner section comprising a front wall, a back wall and two connecting walls, each of the walls having an internal face and an outer face, said outer face of one of said connecting walls of said second profiled being provided with a broom at least partially along its length, said second section having a portion of light forming a cavity of a second substantially U-shaped groove, said front wall having a longitudinal opening forming an opening of said second groove, the adjacent portions of which are formed by two internal lips each extending from one of the connecting walls, said second groove of said second internal section and said first groove of said first external profile forming, when said first and second sections are arranged to cooperate by sliding, an at least partial superposition groove of two sections comprising a longitudinal orifice formed by at least partial alignment of said longitudinal orifice present on the front wall of said first profile and said longitudinal orifice present on the front wall of said second section , said overlay groove at least p Artielle of two profiles being arranged to receive and maintain at least partially a substantially peripheral portion of said closure member. For the purposes of the present invention, the term "slidably cooperate" is intended to mean the overlap of one element at least partially with another or by at least partial insertion of one element concentrically with respect to another. In this case, in this case, the second substantially U-shaped groove of the inner profile slides at least partially in the first substantially U-shaped groove of the outer profile and is therefore at least partially covered by the latter. In this context, the sliding of the inner profile in the outer section of each telescopic post coincides the two grooves above so as to form a single substantially U-shaped groove. In this way by the presence of telescopic amounts, the frame is adaptable to a wide range of dimensions of said opening to be clogged, which does not in any way jeopardize the tightness of the closure of the opening thanks to the peripheral seal-sealing element and the advantageous presence of means restraint. In a particular embodiment, two adjacent amounts of the frame are nested in a junction piece, preferably full, so that the amounts are non-parallel, in particular substantially perpendicular.

Preferably, said junction piece comprises a first end provided with a means of mutual coupling with one end of said outer section of a first telescopic upright and a second end provided with a means of mutual coupling with one end of said internal section of a second adjacent telescopic upright, said connecting piece having on said first end a groove arranged to cooperate with said groove of said outer profile of said first upright and having on said second end a groove arranged to cooperate with said groove of said inner section of said second upright; . The presence of the connecting piece allows to orient the placement of the frame uprights against each side of the opening, as described above and in particular in the context of an opening defined by a frame. The connecting piece allows the frame uprights to perfectly fit the profile of the opening since each connecting piece is arranged, during the placement of the frame, to abut against the corners of said opening, which reinforces the sealing of the shutter system. Alternatively, said joining piece has a groove on a front face arranged to connect said groove of said first end and said groove of said second end of the joining piece and thus form a single continuous groove. In this way, the substantially peripheral portion of the closure member can be attached to the joining piece so that the tightness of the seal-sealing member is ensured both at the joining piece and at the level of each amount forming the frame. In a particularly advantageous embodiment of the closure system according to the invention, at least one retaining means has a bottom wall and two side walls facing each other, said side walls extending from said bottom wall and having, on the one hand, an outer face intended to face an inner face of said substantially U-shaped groove of a profile forming an amount of said frame. According to another embodiment, the outer face of each side wall of said at least one retaining means is intended to face an inner face of a groove formed when said first and second sections of a telescopic upright are arranged to cooperate. by sliding, each of the profiles having a portion of light forming a cavity of a substantially U-shaped groove. In addition, it is provided according to the invention that each external face of said retaining element has at least one protrusion arranged to force the interlocking said retaining piece in said cavity of said groove formed in a slot of a profile forming an upright of said frame or formed when said first and second sections of a telescopic upright are arranged to cooperate by sliding and form a defined groove by sliding said second groove in said first groove. The presence of at least one protrusion, oriented towards an internal face of said groove, on the lateral walls of the retaining means makes it possible to accentuate locally the cohesion and pressure force generated on the walls of said groove. Indeed, the or protuberances exert localized pressure on the closure member and the inner face of the groove when a substantially peripheral portion of said closure member is placed in said groove.

Optionally, for each side wall of said retaining means, each inner face has at least one protuberance oriented in a direction opposite to the protuberance of the outer face. Furthermore, said gasket furthermore has a longitudinal projection of a first predetermined thickness e1 and terminated by a first and a second shoulder, of a predetermined height h1, to form an assembly of a second predetermined thickness e2, said lateral walls of the retaining means being separated from each other by a predetermined distance d1, so that d1 <e2, each shoulder of the seal being arranged to be placed between the bottom wall of the retaining means and each projection have on the internal faces of the side walls of the retaining means. Advantageously, the projection of each inner face of the retaining means has a third predetermined thickness e3 and is placed at a second predetermined distance d2 from the bottom wall of the retaining means, so that e3> e2 - el and / or that of hl> d2. In this way, the seal, once fitly housed in the retaining means, by the presence of the projections on the inner faces of the retaining means, is integrally bonded to the latter. In this way, when replacing the closure element, the withdrawal of the seal out of a groove formed of a profile forming a frame upright or out of a groove formed by the sliding of a groove of the second internal section in a groove of the first outer section of a telescopic post, is carried out together with the withdrawal of said retaining means. This allows a faster removal of the shutter member from its location, for example, when the last one is damaged. It then suffices then to those skilled in the art to separate the retaining means and seal, to place a new closure element, a retaining means, and a seal to form easily and again another sealing system.

Preferably, the connecting piece is intended to be positioned inside an opening, such as a door or window opening defined by a door frame or of a type delimited by adjacent walls, and to cooperate with a pair of telescopic posts. adjacent, a frame arranged to accommodate a closure member, for example a tarpaulin. Each telescopic post comprises a first outer section having a portion of light forming a first substantially U-shaped groove, and a second inner section having a portion of light forming a second substantially U-shaped groove, said second groove of said second internal section and said first groove of said first outer profile forming, when said first and second sections are arranged to cooperate by sliding, an at least partial superposition groove, comprising a longitudinal orifice formed by the at least partial alignment of a longitudinal orifice present on a front wall of said first profile and a longitudinal orifice present on a front wall of said second section. Said at least partial superposition groove is further arranged to receive and at least partially maintain a substantially peripheral portion of a closure element, for example an edge of a sheet. Said first end of the junction piece is arranged to be fitted at one end of said first outer profile of a first telescopic upright, said second end of said connecting piece being arranged to be engaged at one end of said second internal section of a second telescopic post adjacent to said first telescopic post. A substantially peripheral portion of said shutter member is intended to be housed in the lumen forming a cavity of the groove of the first or second section, or in said at least partial superposition groove of two sections, each groove being arranged to accommodate, at least partially, fittingly a seal for securing said substantially peripheral portion of said closure member in said groove.

For the purposes of the invention, the term "embrace" means that an element is covered and retained at least partially by another or by at least partial insertion of one element into another, for example concentrically. In this case, for example, one end of each telescopic post is engaged at least in a portion of each end of the joining piece.

Said first end of said junction piece has a first longitudinal groove arranged to be housed, at least partially, in the light forming a cavity of said groove of said outer profile of the first upright, and in that said second end of said connecting piece. has a second longitudinal groove intended to be housed at least partially in the lumen forming a cavity of said groove of said inner profile of the second adjacent upright, each of the grooves being arranged to accommodate, at least partially, said seal, over a part of said shutter element superimposed on said junction piece. In this way, the first groove of the first end of the junction piece housed in the light forming a cavity of the groove of the outer profile and the second groove on the second end of the junction piece housed in the cavity-forming light the groove of the inner profile form a continuity of the fastening means of the closure member present on each profile. When the seal is placed in the groove of the outer profile of a first upright, adjacent to the connecting piece, it allows the attachment of a substantially peripheral portion of the closure member in the groove of the outer profile. The same seal is also housed at least partially in the lumen forming a cavity of the first groove of the first end of the connecting piece, over the substantially peripheral portion of the closure member which covers the joining piece. Preferably, the seal extends at least until it comes into contact with at least one of the side walls of the opening to be closed. In addition, the seal of the second adjacent upright is placed at least partially in the groove of the inner profile of the second upright, over the closure member and thus fixes a substantially peripheral portion of the closure member, namely, the peripheral portion perpendicular to the peripheral portion housed in the first amount. The same seal is also housed at least partially in the light forming a cavity of the second groove on the second end of the connecting piece, over said substantially peripheral portion the closure member which covers the joining piece. Preferably, the gasket of the second upright extends at least until it comes into contact with at least one of the side walls of the opening to be closed and rests simply over the gasket of the first upright. This therefore makes it possible to provide a perfect seal since the joining piece partially accommodates the seal. In addition, each seal is extended so that a free portion of the seal of the second upright is superimposed on another free portion of the seal of the first upright. Each free seal portion is therefore a gripping means of the seal. In this way, to remove the shutter member of the frame, it suffices for the skilled person to grasp the free portion of each seal to dislodge the joint grooves of the junction piece and adjacent amounts in which the joints are housed. Indeed, the superposition of the joint parts, not engaged in the grooves of the joining piece, allows to maintain sufficiently the shutter element, and this, even under the superposition of the free joint parts, where the element d shutter is not engaged in each groove of the joining piece, and this by the natural rigidity of the seal housed in the light forming a cavity of the groove for a distance long enough for the seal to exert a force on the element of shutter resting along the corner piece. It therefore appears that the joint presence of the first groove on the first end of the connecting piece and the second groove on the second end of the joining piece, each end being adjacent to the zone where the free parts of seal are superimposed, allows a sufficient maintenance of the seals so that the tearing of the shutter member is prevented when the latter is subjected to a force, for example a force exerted by a stream of air. A hermetic junction is then established between, on the one hand, the connecting piece, and, on the other hand, the substantially peripheral portion of the closure member. Furthermore, the joining piece according to the invention is preferably a corner piece and advantageously has a substantially L shape so that said first upright is oriented substantially perpendicular to said second upright. The connecting piece is further characterized in that it has a flap on a front face, said flap being arranged to cover, at least partially, a front face of said first outer profile of a first telescopic upright and a front face. said second inner profile of a second telescopic post. The presence of the flap makes it possible to obstruct any gaps created between the walls of the opening and the junction part of the frame, thus ensuring the impermeability of the system in the corners of the opening to be obstructed. Optionally, the connecting piece comprises, between said first end and said second end, a solid part arranged to receive on one side, in abutment, said outer profile of the first upright and on the other side, in abutment, said profile. internal of said second amount. The dust therefore does not know how to enter the profile via the corner piece since, on the one hand, the passage is blocked at the joint seal-closure element, and, on the other hand, since the part of the junction piece in which the seal is not housed is full.

In a particular embodiment, said solid portion of said junction piece is made of a flexible material, rubbery type. In this way, there is sealing of the hollow part of the profile 5 and prevention of the passage of dust beyond the joint-sealing member. In a variant of the present invention, said junction piece comprises a third end and has a substantially T-shaped shape, said first end being arranged to be fitted to one end of said first outer profile of a first telescopic upright, said second end said connecting piece being arranged to be engaged at one end of said second inner profile with a second telescopic post adjacent to said first telescopic post, said first post being substantially aligned with said second post, said third end being arranged to be engaged with a end of said first outer profile or said second inner profile of a third upright said third upright being substantially perpendicular to said first and second uprights. Preferably, said T-junction piece comprises, between each end, a solid portion arranged to receive, from a first side, in abutment, said outer profile of the first upright, a second side, in abutment, said internal profile. said second amount, and a third side, in abutment, said internal or external section of said third amount. In a particular embodiment, said solid portion 25 of said junction piece is made of a flexible material, rubbery type. Preferably, said third end has a third longitudinal groove arranged to be housed, at least partially, in the cavity-forming light of said groove of said outer profile or in said groove of the inner profile of said third upright. The presence of a T-junction piece is particularly recommended when the opening to be obstructed has large dimensions, that is to say at least 150 cm (or a multiple of at least 150 cm) in width. and at least 150 cm (or a multiple of at least 150 cm) in height. This opening having large size, it is difficult for the skilled person to put in place the shutter system alone to close with a single shutter element this opening. Therefore, the presence of a T-junction piece allows to place at least a third amount, dividing the opening defined by the frame into two openings of smaller sizes that can easily be each covered by a closure member.

It should be noted that for openings having a high height, that is to say at least 150 cm (or a multiple of at least 150 cm), several telescopic uprights can be connected two by two by a junction piece having a first end facing a second end, so that two adjacent posts connected to the same junction piece are aligned with each other. The invention furthermore relates to a method for closing off an opening, such as a door or window opening defined by a frame or of a type delimited by adjacent walls, comprising the following steps: a junction of at least four uprights two by two by a connecting piece to form a frame, each section forming an amount of said frame, said connecting piece having a first end arranged to be connected to a first upright, and a second end arranged to be connected to a second upright adjacent to said first post - placing the frame within the opening so that it bears against each side of said opening - inserting at least a substantially peripheral portion of a post closing in a groove present in each section or in a groove formed by the sliding of a second groove of a second internal profile in a first go a first outer profile of a telescopic upright, when said first and second sections are arranged to cooperate by sliding, and - an adjusted positioning of at least one seal in said groove present on each profile to fix said at least one a substantially peripheral portion of the closure element, so as to form a closure system of said opening, characterized in that it comprises a step prior to that of positioning said at least one joint, wherein a means of retaining, having a first predetermined profile complementary to a second profile formed by said groove and inner lips defining its opening, is placed in said groove between said substantially peripheral portion of a closure member and said seal, superimposed above said at least one substantially peripheral portion of a closure member so as to retain it on a ledi frame and to accommodate said seal having a third predetermined profile arranged to cooperate with said first predetermined profile of said retaining means. Advantageously, the closure method according to the invention comprises, prior to said step of joining at least four sections two by two to form the frame, a step of telescopic deployment of two profiles arranged to cooperate by sliding and forming an amount said frame so that at least one connecting piece abuts against one of the corners of the opening. For example, each upright is a telescopic upright comprising a first outer profile and a second inner profile, said first and second profiles being arranged to cooperate by sliding. Optionally, said telescopic deployment step of each post of said frame is followed by a blocking step in which said first external section is momentarily fixed in a predetermined position relative to that of said second internal section. Optionally said blocking step is followed by a step in which two adjacent amounts of said frame are interconnected by additional compensation means arranged to exert a thrust on each post so that they bear against the sides of the frame. opening.

Each lateral flap 451, 452 is disposed on either side of the second end 47. the connecting piece to form a first gap between this second end 47 and a first lateral flap 451, and a second gap, between the second end 47 and a second lateral flap 452. Each interstice is arranged to accommodate in a manner adjusted at least an end portion of the second inner profile 1 of the second telescopic upright 1 ".

FIG. 10 illustrates a particular embodiment of the connecting piece according to the invention. In this particular embodiment, the front flap 50 has a front groove 453 arranged to receive a front seal 454, over a portion of said closure member 27. In a variant, the junction piece 45 comprises a third end and presents a substantially T-shaped. The first end 46 is arranged to be engaged at one end of the first outer profile 12 of the first telescopic upright 1 ', the second end 47 of the connecting piece is arranged to be engaged at one end of the second section internal 1 of the second upright 1 "telescopic adjacent to the first upright 1 'telescopic, the first upright 1' being substantially aligned with the second upright 1". The third end is arranged to be engaged at one end of the first outer profile 12 or the second inner section 1 of a third upright substantially perpendicular to the first 1 'and second uprights 1 ".

The T-junction piece comprises, between each end, a solid portion 52 arranged to receive, from a first side, in abutment, the external profile 12 of the first upright 1 ', of a second side, in abutment, the internal profile 1 of the second upright 1 ", and a third side, in abutment, the inner or outer profile of the third upright, preferably the solid portion 52 is made of a flexible material, of the rubbery type. the connecting piece has a third longitudinal groove arranged to be housed, at least partially, in the groove of the outer profile 12 or in the groove of the inner section 1 of the third upright.

The presence of a T-junction piece is particularly recommended when the opening to be obstructed has large dimensions, that is to say at least 150 cm (or a multiple of at least 150 cm) in width. and at least 150 cm (or a multiple of 150 cm) in height. This opening having large size, it is difficult for a person skilled in the art to put only the shutter system in place so as to close with a single shutter element this opening. Therefore, the presence of a T-junction piece allows to place at least a third amount, dividing the opening defined by the frame into two openings of smaller sizes that can easily be each covered by a closure member.

It should be noted that for openings having a high height, that is to say at least 150 cm (or a multiple of at least 150 cm), several telescopic uprights can be connected two by two by a junction piece having a first end facing a second end, so that two adjacent posts connected to the same junction piece are aligned with each other. Preferably, the frame is a telescopic system comprising at least four telescopic uprights. The frame is furthermore arranged to be positioned in an opening, of the door or window opening type delimited by a frame or of a type delimited by adjacent walls, said telescopic system being furthermore arranged to receive a closure element, for example for example a tarpaulin, and further comprising at least four connecting pieces, in particular a corner piece, in which two perpendicular adjacent uprights are nested.

Advantageously, said two adjacent perpendicular amounts nested in a junction piece are further connected by a compensation means, for example by a flat spring. The presence of these compensation means is particularly recommended in the case where the rigidity of the frame is not sufficient, it may happen that the amounts flare inwardly of the opening. This is particularly the case for telescopic amounts forming a frame arranged to fit into an opening having large dimensions, for example, of dimension of at least 150 cm (or a multiple of at least 150 cm) over 150 cm (or a multiple of at least 150 cm).

In addition, to maintain each amount against the sides of the opening, compensation means can be implemented. The latter push each amount against the sides of the opening vis-à-vis. Each compensation means is put in place in each corner of the frame and comprises a flexible strip, for example of the spring steel strip type, also called flat spring, and two fixing means, for example of the screw-nut system through the strip , whose screw passes through one end of the slider to screw into a nut housed in the amount considered. The slide is then disposed inside the frame opposite a junction piece. The strip is fixed on each of the adjacent frames so as to be pushed into the corner of the frame so as to take a shape in an arc whose center of curvature is oriented towards the center of the opening defined by the frame. In this way, the compensation means create a circular deployment acting on each upright so that the interlocking of these uprights in their joining piece is consolidated by the circular thrust action induced by the presence of the strips, each placed in an arc circle. The strip may have for example a thickness between 1 mm and 2 mm and a length of between 60 cm and 80 cm. Optionally, the fixing means of each compensation means comprise a series of at least one slot present on each upright and in which each end of the strip is inserted. In a preferred embodiment, for openings having large dimensions, i.e., a width and / or height of at least 150 cm (or a multiple of at least 150 cm), the shutter opening is performed by placing at least two frames, one after the other, in the direction of the length or height (or both), each of the two frames 25 having two pairs of amounts connected to each other by four pieces of junction L. In this context, each of the neighboring frames then has an amount in contact with an amount of the other frame. In particular, those skilled in the art will be careful to orient the L-shaped junction pieces so that two adjacent junction pieces, each belonging to a distinct frame, are arranged so that a first end 46 of a first junction piece 45 of a first frame is disposed adjacent a second end 47 of a second junction piece 45 'of a second frame, so that the circular thrust effect of the springs placed on the first frame compensate for the circular thrust effect of the springs on the second frame, so as to stabilize the telescopic posts in a predetermined sliding position. Optionally, additional compensating means can be placed between two opposite large amounts to stabilize the frame. The establishment of the closure system, preferably comprising telescopic uprights, comprises the following steps: a junction between two adjacent uprights by a connecting piece 45 for closing a frame, the joining piece 45 having a first end 46 arranged to be connected to a first upright 1 ', and a second end 47 arranged to be connected to a second upright 1 ", - a placement of the frame within an opening, - a possible extension of the telescopic uprights by sliding of an internal profile 1 in an outer profile 12 forming the telescopic upright, so that the connecting pieces 45 abut against the corners of the opening, - a blocking of the inner and outer profiles 12 and 12 by tightening blocking means, optionally followed by a mounting of compensating means for stiffening the frame, - an insertion of at least a substantially peripheral part of a sealing member 27 in a groove present in each upright or in a groove formed by the sliding of a second groove (7) of a second internal section (1) in a first groove (20) of a first external section (12) a telescopic upright, when said first and second profiles are arranged to cooperate by sliding, and an adjusted positioning of at least one seal 29 through the opening of the groove 22 of each upright to fix the portion therein. substantially peripheral of the closure member, so as to form a closure system of the opening.
