Description

Title of the invention: PALISSADE SYSTEM

[0001] BACKGROUND OF THE INVENTION

[0002] The present invention relates to the field of palisade systems comprising several palisade modules connected to each other by at least a first flange.

[0003] It is known to form a palisade system by forming a succession of palisade modules each having a frame and a first panel and by connecting these palisade modules two by two using flanges.

[0004] It has been found that some palisade systems deteriorate under the effect of mechanical stresses such as vibrations (for example under the effect of wind) or under the effect of people who seek to dismantle the palisade system by tearing off the panels or flanges.

[0005] It is therefore necessary to provide a palisade system having improved strength.

[0006] SUBJECT OF THE INVENTION

[0007] The invention aims in particular to provide a palisade system solving all or part of the aforementioned problems of the prior art. Summary of the invention

[0008] To this end, according to the invention, a palisade system is provided comprising at least first and second palisade modules, each given module comprising: - a frame having a right upright and a left upright substantially parallel to each other and upper and lower crosspieces substantially parallel to each other; - a first panel carried by the frame to define at least part of a first main face of the given module; the palisade system comprising at least a first flange arranged to connect said first and second palisade modules together while keeping the right upright of the first module substantially parallel to the left upright of the second module.

[0009] The palisade system according to the invention is essentially characterized in that it comprises at least a first cover extending opposite a space formed between the right upright of the first module and the left upright of the second module, the first cover preventing access to said first flange from a first side of said palisade system.

[0010] Thanks to the invention, the cover makes it possible to stiffen the connection between the two modules while preventing access to said at least one flange from the first side of the palisade system, which prevents any possibility of degradation of the connection between the two modules by a person located on the said first side of the palisade system.

[0011] Furthermore, the presence of the cover to mask the space between the panels makes it possible to limit the visibility of the area preserved by the palisade system, as well as the visibility of said at least one first flange.

[0012] It then becomes difficult to understand which clamping / flange locking system is used to assemble the panels together.

[0013] It should be noted that all or part of the flanges, including the first flange, may be equipped with a so-called "tamper-proof" tightening means in that it requires special tools to disassemble the flange (for example a key with only three sides or only 5 sides or only 7 sides) and / or a flange with a self-breaking tightening head when a predetermined tightening torque is applied to the tightening head of the flange.

[0014] Hiding the flange thus limits the risk of a malicious person knowing which tools to use to loosen the flanges.

[0015] The cover thus limits curiosity / lust, and the risk of break-ins on the site hidden by the palisade system.

[0016] This invention is thus particularly useful since it makes it possible, at low cost, to reinforce the mechanical resistance of the palisade system as well as its resistance to vandalism (the first side of the palisade system here being the side accessible to the public, the other side of the palisade system being oriented towards the area preserved by the palisade system).

[0017] Preferably, said first cover is connected to said first flange to be held fixedly relative to the frames of the first and second modules of the palisade system.

[0018] With this embodiment, the cover is not fixed on the frames of the modules, but it is fixed and carried at least by the first flange which implies that the cover can be compatible with any module, this cover having to be adapted to the flange used, knowing that the flanges used to assemble modules are generally all identical to each other and are standard flanges.

[0019] Preferably, said cover is made of metal, preferably stainless steel.

[0020] Preferably, the palisade system comprises a plurality of flanges identical to the first flange, a first group of the flanges of the plurality of flanges being arranged to connect said first and second palisade modules together, each of the flanges of the first group being, in the same manner as the first flange, arranged to hold the right upright of the first module substantially parallel to the left upright of the second module, the first cover being held fixedly relative to the first and second modules by several of the flanges of the first group of bridle and by the first bridle.

[0021] More particularly, the flanges holding the first cover are arranged to clamp it against the uprights using jaws belonging to the flanges of the first group of flanges (all the flanges of the first group of flanges are preferably identical to the first flange).

[0022] The flanges of the first group of flanges and the first flange are arranged at different levels to connect together the right and left uprights of the first and second modules at different heights of the fence system.

[0023] Preferably, in any one of the embodiments of the invention, the first cover is exclusively carried by flanges of the first group, the first flange being one of the flanges of the first group of flanges.

[0024] Preferably, the right and left uprights are connected to each other by at least three flanges, including said first flange (these three flanges belong to the first group of flanges).

[0025] Thus, the cover is preferably fixed to the modules by means of at least three flanges arranged at different heights of the palisade system, which reinforces the mechanical cohesion of the palisade system.

[0026] An example of the embodiment of a flange will be presented below with reference to the drawings, this example being applicable to all or part of the flanges of the palisade system according to the invention.

[0027] At least some of the flanges of the palisade system, including said first flange, may comprise a self-breaking clamping head when it receives a tightening torque greater than a predetermined tightening torque value.

[0028] In any embodiment of the invention, it is preferable that all the flanges are identical to the first flange to facilitate the arrangement of the palisade system by adding as many modules as necessary while having a single flange model to connect, two by two, the different modules of the system.

[0029] According to a preferred embodiment of the system according to the invention, each given module comprises a second panel carried by the frame of said given module and parallel to the first panel of the given module, the first cover being on the one hand in abutment against the second panel of the first module to press it against the first panel of the first module and on the other hand in abutment against the second panel of the second module to press it against the first panel of the second module.

[0030] With this preferred embodiment, the mechanical resistance of each given module is increased by adding a second panel to it while consolidating the connection between the modules since the first cover is shaped to press against the second panels of the modules adjacent to it.

[0031] Other advantages of this preferred embodiment will be presented in the detailed description.

[0032] Preferably, each second panel of a given module comprises folded vertical lateral edges which extend towards the first panel of said given module so as to increase the buckling resistance of the given module.

[0033] This feature also reduces the risk of the first and second panels vibrating against each other.

[0034] Preferably, the first and second panels of each given module each have an upper edge penetrating into at least one longitudinal recess of the upper crosspiece of the given module and a lower edge penetrating into at least one longitudinal recess of the lower crosspiece of the given module.

[0035] This mode makes it possible to improve the mechanical resistance of each module since the panels of the same module are engaged on the same upper and lower crosspieces of the structural frame of the module.

[0036] According to another aspect, the invention also relates to a method of manufacturing a palisade system according to the previous embodiment, the method comprising:

[0037] - the use of palisade modules each comprising a single panel, called first panel;

[0038] - the assembly of at least one second panel on each palisade module by insertion of its upper edge of the second panel into the longitudinal recess of the corresponding upper crosspiece and of the lower edge of the second panel into the longitudinal recess of the corresponding lower crosspiece; then

[0039] - the installation of the first cover to apply forces with the first cover opposing the bending of the second panels towards the first side of the palisade system.

[0040] This manufacturing method is advantageous in that it allows palisade modules having a single panel to be transformed into modules comprising two panels which are stiffened by means of the first cover which presses against the second panels which are adjacent to it.

[0041] Other characteristics and advantages of the invention will emerge from reading the following description of a particular and non-limiting embodiment of the invention. Brief description of the drawings

[0042] Reference will be made to the accompanying drawings, among which:

[0043] [Fig. 1a] [Fig. 1a] is a front view of a palisade system 0 according to the invention observed from its first side Cx (the second panels are here made transparent to be able to show the first panels 41 of these modules which are here corrugated sheet panels);

[0051] [Fig.5] [Fig.5] is a side view of a part of the system 0 of figures 1a and 1b, this [Fig.5] making it possible to illustrate the positioning of the strut 7 of which the lower end 7b is also connected via a horizontal tie rod 9 to a second flange of the palisade system placed below the first flange Bl. This second flange connects the modules together in the same way as the first flange Bl, but at a lower height of the palisade. This allows effective triangulation preventing the palisade from tipping over in the event of strong winds / strong thrust from one side of the palisade. DETAILED DESCRIPTION OF THE INVENTION

[0052] As indicated above, the invention relates to a palisade system 0 illustrated in FIGS. 1a to 5, comprising at least first and second palisade modules 1, 2, 2'.

[0053] The second module is referenced 2 when it designates a second module 2 coplanar with the first module 1 (as in figures 1a to 2c and 4).

[0054] The second module is referenced 2' when it designates a second module 2' which is perpendicular to the first module 1 (as in figures 1a, 1b, 3a, 3b).

[0055] Each given module, 1, 2, 2' comprises: - a frame 3 forming a rigid structure and having a right upright 31, 31' and a left upright 32, 32' substantially parallel to each other and upper and lower crosspieces 33, 34 substantially parallel to each other; - a first panel 41 being carried by the frame 3 to define at least a part of a first main face F1 of the given module.

[0056] Reference 31 designates the right upright of the first module 1.

[0057] Reference 31' designates the right upright of the second module 2.

[0058] Reference 32 designates the left upright of the first module 1.

[0059] Reference 32' designates the left upright of the second module 2.

[0060] The palisade system 0 comprises at least one first flange Bl arranged to connect said first and second palisade modules 1, 2, 2' together while keeping the right upright 31 of the first module 1 substantially parallel to the left upright 32' of the second module 2.

[0061] The system 0 comprises at least a first cover 5 extending opposite a space E formed between the right upright 31 of the first module 1 and the left upright 32' of the second module 2.

[0062] The first cover 5 which is preferably a sheet metal (for example a stainless steel sheet metal) prevents access to said first flange B1 from a first side Cx of said palisade system O.

[0063] Preferably, the system comprises a plurality of flanges identical to the first flange B1, each of the flanges of the plurality of flanges being arranged for connect adjacent uprights belonging to adjacent modules of the palisade system.

[0064] The flanges are identical to each other except that at least some of the flanges of the plurality of flanges may include a self-breaking clamping head when a tightening torque of a predetermined value is applied to a self-breaking clamping head of the flange. A flange with a self-breaking clamping head is called a "tamper-evident flange".

[0065] It should be noted that the modules are preferably identical to each other in such a way that a palisade system can be created by aligning as many modules as necessary and connecting them two by two using identical clamps, each of the clamps clamping on one side an upright of one of the modules and on the other side another upright of another of the adjacent modules. The only difference allowed between the identical clamps being that some of these clamps may have a self-breaking clamping head while some other of these clamps may have reversible clamping heads (that is to say, after tightening the clamping head, it is possible to loosen this so-called reversible head to reuse this same clamp with its reversible clamping head in order to connect two other modules).

[0066] Each frame 3 of a given module has an external peripheral contour closed on itself which is defined by the succession of the right upright 31, the lower crosspiece 33, the left upright 32 and the upper crosspiece 34 of the given module, this peripheral contour extending in a main plane of the given module.

[0067] Preferably, to prevent deformations of the frame, for each given frame 3, the ends of the upper and lower crosspieces of the given frame 3 are respectively rigidly fixed against the right and left uprights of the given frame 3, these rigid fixings being preferably made with welds, each given frame being preferably metallic.

[0068] As understood from [Fig. 1a], each frame 3 may also comprise bracing links 30, 31 each connecting a crosspiece of the frame to an upright of the frame 3.

[0069] As illustrated in Figures 1a, 1b, 2c and 4, the first and second modules 1, 2 connected to each other by the first flange B1 can be arranged so that the first panels 41 of these respective modules are parallel to each other.

[0070] This assembly method can be used to assemble a linear succession of identical palisade modules, the adjacent modules of the linear succession of modules being assembled together by means of at least one pair of flanges, all the flanges of the palisade system being identical to each other and consequently identical to the first flange B1 (the only difference between identical flanges (it may be that some clamping heads of these flanges can be self-breaking or reversible).

[0071] Alternatively, as illustrated on the corners of the fence visible in figures 1b, 3b, the first and second modules 1, 2' can be arranged so that the main planes of the first and second modules are perpendicular to each other.

[0072] For the record, a main plane of a given module is the plane in which the peripheral contour of the frame 3 of the given module extends.

[0073] In this latter case, illustrated in figures 3a, 3b, the first panels 41, 42 of the first and second modules 1, 2 are perpendicular to each other, a second cover 50 then extending against the first cover 5.

[0074] These first and second covers 5, 50 have rectilinear longitudinal edges in continuous contact with each other, the first flange B1 compressing the longitudinal edges of the first and second covers 5, 50 against each other by pressing them against one of said uprights 31 of the palisade system 0 which is engaged with the first flange B1.

[0075] In all the illustrated modes, said first cover 5 is connected to said first flange B1 to be held fixedly relative to the frames 3 of the first and second modules 1, 2 of the palisade system 0.

[0076] The first flange B1 comprises a first jaw in which the right upright 31 of the first module 1 is clamped and a second jaw in which the left upright 32' of the second module 2 is clamped.

[0077] The first cover 5 comprises a first portion 51 clamped in one of the first or second jaws of the first flange BL

[0078] More particularly, as understood from [Fig.4], the first clamped portion 51 of the first cover 5 belongs to a first folded lateral edge of the first cover 5.

[0079] In at least some of the embodiments where the modules are coplanar with each other, the first cover 5 also comprises a second portion 52 clamped in the other of the first or second jaws of the first flange BL.

[0080] Thus, the two jaws of the same flange B1 are arranged to be able to simultaneously clamp the first and second portions 51, 52 of the first cover 5.

[0081] This allows for rigidity in positioning the hood using at least one flange.

[0082] More particularly, the second clamped portion 52 of the first cover 5 belongs to a second folded lateral edge of the first cover 5.

[0083] This first cover 5 is a profile extending lengthwise along the right upright 31 of the first module 1 and along the left upright 32' of the second module 2.

[0084] As illustrated in [Fig.4], this first cover 5 observed in a sectional plane transverse of the first cover 5 has a C-shape, the C-shape having first and second terminal ends moving towards each other.

[0085] The first terminal end of the C-shape belongs to the first folded lateral edge of the first cover 5 and the second terminal end of the C-shape belongs to the second folded lateral edge of the first cover 5.

[0086] Preferably, each given module 1, 2 comprises a second panel 42 carried by the frame 3 of said given module and parallel to the first panel 41 of the given module.

[0087] The first cover 5 is on the one hand in abutment against the second panel 42 of the first module 1 to press it against the first panel 41 of the first module 1 and on the other hand in abutment against the second panel 42 of the second module 2 to press it against the first panel 41 of the second module 2.

[0088] Thus, not only does the first cover 5 make it possible to mask the space E between the frames 3 of the first and second modules 1 and 2, but it also makes it possible to clamp the first and second panels 41, 42 of the same module against each other, which: - increases the mechanical strength of the first and second modules 1,2; - prevents access to the first flange B1 from a first side Cx of the palisade system while preventing the tearing of the second panels 42 which are thus held in place thanks to the support of the first cover 5 against the second panels 42.

[0089] Preferably, the first hood is carried exclusively under the effect of pinching of the first hood produced by several of said flanges, including pinching of the first hood produced by the first flange.

[0090] Preferably, the first cover 5 has a length equal to at least 70%, preferably at least 80% of the length of the right upright 31 of the first module 1 and at least 70%, preferably at least 80% of the length of the left upright 32' of the second module 2.

[0091] Thus, the cover makes it possible to protect the majority of the height of the palisade system by preventing access to all the flanges from the first side Cx.

[0092] Preferably, the right and left uprights of the first and second modules 1, 2 are of the same length and parallel to each other.

[0093] As understood from Figures 1a and 5, each of the uprights comprises a lower portion which preferably extends below a level in which the lower crosspiece 33 extends.

[0094] These lower parts of the uprights are arranged to penetrate into feet P for holding the modules of the palisade system 0 vertically.

[0095] Each foot P has pairs of perforations.

[0096] The perforations of a given pair of perforations are spaced apart by a distance such that the lower parts of uprights connected to each other by the same flange B1 can respectively be positioned in the perforations of the pair of perforations of the foot P.

[0097] Typically a foot P is a substantially prismatic block comprising several pairs of perforations.

[0098] Said mass M used to ballast the strut 7 may consist of one or more prismatic blocks of a shape identical to a foot P.

[0099] A foot preferably weighs more than 20 kg, possibly more than 25 kg.

[0100] Preferably, the frames 3 of the first and second modules 1, 2 are of identical shapes and dimensions between the frames 3.

[0101] We will now describe an embodiment of a flange Bl.

[0102] As understood from Figures 2a to 4, the first flange B1 preferably comprises initially, first and second elongated parts B 1a, B 1b and a clamping mechanism B 1e.

[0103] The first and second elongated parts B la, B lb are connected to each other by means of the clamping mechanism B le.

[0104] The first and second elongated pieces B 1a, B 1b are also shaped to define between them a first space for receiving the right upright 31 of the first module 1 and a second space for receiving the left upright 32' of the second module 2, the right upright 31 of the first module 1 being placed in the first receiving space by being clamped between the first and second elongated pieces B 1a, B 1b of the first flange B 1 and the left upright 32' of the second module 2 being placed in the second receiving space by being clamped between the first and second elongated pieces B 1a, B 1b of the first flange B 1

[0105] More precisely, the first reception space is defined between first ends, each C-shaped, of the first and second elongated parts B1a, B1b of the first flange BL

[0106] These C-shapes are complementary to an external profile common to all the uprights of the different modules so as to be able to come to bear against and around any of the uprights of the palisade system 0.

[0107] In this way each receiving space of a given flange is adapted to clamp any of the uprights of the palisade system 0.

[0108] These first and second elongated parts B1a, Blb of the first flange B1 together define said first and second jaws of the first flange B1.

[0109] The clamping mechanism B of the first flange B1 comprises: - a clamping axis which passes through perforations respectively formed through the first and second elongated parts B1a, B1b of the first flange B1; and - a screw-nut system exerting a compressive force on the first and second elongated parts B1a, B1b of the first flange B1 towards each other, the screw-nut system may or may not be fitted with a self-breaking clamping head.

[0110] As understood from Figures 2a to 4, each second panel 42 of a given module preferably comprises folded vertical lateral edges 421, 422 which extend in the direction of the first panel 41 of said given module so as to increase the buckling resistance of the given module.

[0111] Thus, the modules 1, 2 are both more resistant to lateral thrust forces exerted against the modules (for example forces exerted by a crowd against the first side of the palisade system) and against compression forces which tend to push the upper crosspiece 34 towards the lower crosspiece 33 (this type of force being for example generated when a person climbs the palisade).

[0112] Preferably, each first panel 41 has a wavy shape in a direction parallel to the upper and lower crosspieces 33, 34 of the given module and each vertical lateral edge 421, 422 of the second panel 42 of the given module extends at least partly in a hollow of a wave of the first panel 41 of said given module.

[0113] A reinforcement of the module is thus obtained by using the corrugated sheet space of the first panel 41 to position the lateral edges 421, 422 of the second panel 42 there.

[0114] Preferably, each second given panel 42 of a given module comprises a main flat face extending between the vertical lateral edges 421, 422 of the second given panel 42.

[0115] The fact that each second panel 42 is flat between its lateral faces makes it possible to obtain a large flat surface which is particularly useful as a communication / decoration support, for example by gluing a display film or applying a poster, display panels, painting or other communication support.

[0116] Preferably each second panel is made of stainless steel, preferably brushed stainless steel.

[0117] As illustrated in the detail of [Fig. 1b], the same given module may comprise several second panels 42 whose vertical lateral edges are folded towards the first panel 41 of the given module, these second panels having vertical lateral edges adjacent to each other.

[0118] In this way, in the case where the distance between the uprights of the same module is significant, to facilitate the insertion / manufacturing of the second panels, it is possible to use several second panels of reduced sizes.

[0119] The adjacent vertical lateral edges of the second panels 42 also have a stiffening effect on the entire module once it is assembled.

[0120] The first and second panels 41, 42 of each given module each have a upper edge penetrating into at least one longitudinal recess of the upper crosspiece 34 of the given module and a lower edge penetrating into at least one longitudinal recess of the lower crosspiece (33) of the given module.

[0121] More particularly, as can be understood from the detail illustrated in [Fig.5]: - each upper crosspiece 34 of the palisade system 0 may comprise one or more rectilinear profiles 34a, 34b each having a U-shaped cross-section, said at least one longitudinal recess of the upper crosspiece 34 extending into the U-shaped cross-section of at least one of these profiles (here the profile 34a); and - each lower crosspiece 33 of the palisade system 0 is a rectilinear profile of U-shaped cross-section, the longitudinal recess of the lower crosspiece 33 extending into the U-shaped cross-section.

[0122] The upper crosspiece 34 in [Fig.5], comprises first and second U-shaped profiles, 34a, 34b.

[0123] The second U-shaped profile (here the profile 34b) can extend longitudinally in the first of the U-shaped profiles (here the profile 34a), the first profile 34a being removably assembled on the second profile 34b, for example by screwing here noted 34V.

[0124] In this embodiment: - the upper edge of the first panel 41 (here the panel 41 is a corrugated sheet) is placed in a longitudinal recess belonging to the second U-shaped profile 34b which is inserted into the first U-shaped profile 34a; and - the upper edge of the second panel 42 (which is here a flat sheet with the vertical edge 421 curved and extending in a wave of the first panel 41) is placed in a longitudinal recess belonging to the first U-shaped profile 34a of the upper crosspiece 34.

[0125] In fact, even if these upper edges of the first and second panels 41, 42 are separated from each other by a longitudinal edge of the second U-shaped profile 34b which is inserted into the first profile 34a, these two upper edges are well placed inside the same longitudinal recess which belongs to the first U-shaped profile 34a receiving the second U-shaped profile 34b.

[0126] This embodiment is advantageous for facilitating the assembly and disassembly of the second panel 42, since the first U-shaped profile, 34a of the upper crosspiece 34 receiving the second U-shaped profile 34b of the upper crosspiece can be dismantled to allow the passage of the upper edge of the second panel 42, while maintaining the upper edge of the first panel 41 in the longitudinal recess of the first profile 34a.

[0127] Finally, each second given panel 42 can have an elastic resistance to buckling such that the second given panel 42 can be bent to insert its upper edge into the longitudinal recess of the upper crosspiece 34 which corresponds to it. and its lower edge in the longitudinal recess of the lower crosspiece (33) which corresponds to it.

[0128] Thanks to this characteristic, it is possible to equip at low cost a palisade module equipped with a single first panel 41 with a second panel which mechanically reinforces it.

[0129] This embodiment is compatible with: - a frame 3 whose upper crosspiece 34 is composed of a single U-shaped profile; or alternatively - with a frame 3 whose upper crosspiece 34 is formed of two U-shaped profiles, one of which is removable.

[0130] The second panel 42 also provides a particularly aesthetic external surface that can be used to apply communication.

[0131] Replacing a second panel is simple to carry out, which is particularly advantageous when one wishes to renovate the aesthetics of a public-facing face of a fence, i.e. the first side Cx of the fence system, without having to replace the fence or strip or repaint it.

[0132] The presence of the first cover 5 bearing against the second panels 42 of the first and second modules 1, 2 makes it possible to hold each second panel 42 in the longitudinal recesses of the corresponding upper and lower crosspieces 33, 34, which prevents any risk of the second panels 42 being torn off while the first cover 5 is in place.

[0133] As the first cover 5 extends between the first and second modules 1, 2 to mask the space E between the first and second modules while preventing access, from the first side Cx (i.e. the side where the second panels are located), it is impossible to dismantle the palisade system 0 from this first side Cx.

[0134] Dismantling the palisade system requires passing to the second side of the palisade system to access the flanges and thus allow dismantling of the flanges, the first cover and removal of the second panels 42.

[0135] The invention is particularly advantageous because it makes it possible, at low cost, to secure a palisade system 0 by the presence of the first cover 5 preventing access to the flanges from the first side Cx, while reinforcing each of the modules by the presence of first and second panels pressed against each other under the effect of the first cover.
