Abstract

The palisade has two superimposed panels (1) e.g. rectangular-shaped superimposed panels or square-shaped superimposed panels, where each panel includes a carrying structure, and the panels are assembled by connection of a structure between the panels. The panel is formed from a frame realized with section tubes that are adapted to form the carrying structure. A wind-bracing module (5) is in shape of a bracket whose upright is parallel to the panels, and a branch is perpendicular to the panels. The panels are connected together by an angle module (7) adapted to adjust angle of the panels.

Description

B11154 - stack 1 MODULAR PALLET

Field of the Invention The present invention relates generally to temporary installations and, more particularly, to a modular palisade system. The invention is applicable for example to the realization of building palisades, temporary partitions in exhibition halls, external exhibition walls, etc. PRIOR ART DESCRIPTION Temporary partitions or palisades are often made by means of several identical panels placed side by side. A problem lies in the assembly of the panels together. Documents FR-A-2 900 425 and EP-A-1 849 925 describe a set of elements for the production of a movable partition composed of a set of rectangular panels and at least one rectangular door module all equipped with fastening means with the panel or door module neighbor in width. The securing means are means 20 of interlocking or clipping.

Another problem with temporary installations of partitions or palisades is the safety against a tilting of the structure, in particular under the effect of the wind. Struts inclined relative to the panels on the non-aesthetic side of the partition are generally provided. However, these struts interfere with traffic behind the palisade. It has already been proposed (for example, in the aforementioned documents) to maintain the panels using brackets, one leg resting on the ground and the other pressing against the panel. This does not solve the traffic problem behind the partition near the panels. In addition, such brackets are less effective than struts. It has already been proposed (for example, the aforementioned documents) to complete these brackets by props connecting the partition to the ceiling in order to press it to the ground. Such a solution is however not applicable outdoors and makes the system not versatile. Another problem with temporary partition systems is that for handling, weight, storage and transportation reasons, it is undesirable to make a partition with panels that are too large. In an attempt to remedy this problem, it has already been proposed (for example, the aforementioned EP-A-1 849 925) folding panels in a horizontal direction. This solution limits the possible height and does not solve the problem of handling and weight, the weight of the folded panel being identical to that of the unfolded panel.

Summary An object of an embodiment of the present invention is to provide a removable partition system that overcomes all or part of the disadvantages of the usual solutions.

Embodiments will be described in connection with an example of a palisade application incorporating the multiple functions of the preferred embodiment. These modes of B11154 - stacking

6 realization, however, apply more generally to each function taken individually. Figure 1 is a rear perspective of an embodiment of a palisade by means of a modular and removable system. The system comprises the following modular elements, assembled to each other to form the palisade: panels 1, preferably all identical, of rectangular shape, preferably square; feet 4 adjustable in height; gallows bracing modules 5; angle modules 7; door modules 8; half-panels 9 or termination panels. The realization of a fence does not necessarily require the use of modules of all categories. In particular the door modules 8, angle 7 and half-panels 9 are not necessarily used. The modules of panels 1, half-panels 9, angle 20 7, doors 8 and feet 4 assemble to each other using mechanisms formed of two elements respectively carried by one and the other modules to assemble. The palisade is formed of several panels 1 assembled. Each panel 1 has a rectangular shape (square 25 in a preferred embodiment) and has assembly means to the adjacent panel (laterally or vertically). FIG. 2 is a perspective view of an embodiment of a panel 1 of the type shown in FIG. 1. FIGS. 2A, 2B and 2C are perspective views detailing one embodiment of the mechanism of FIG. assembly of the panels. Each panel 1 is formed of a frame 12, preferably consisting of square section tubes assembled to each other, against a face of which a plate 10 B11154 - stack is attached.

The plate 14 defines the outside of the panel (and the palisade) or the visible face. The plate 14 is fixed to the frame, for example by welding, screwing or by means of rivets 16. The interior of the frame 12 defines a space where the assembly mechanisms are housed. The frame 12 provides rigidity to the panel whose cladding plate can be more or less resistant (for example, a material other than metal, such as fabric, wood, plastic, etc.). Each mechanism comprises a first element 2 (FIG. 2A) or 2 '(FIG. 2B) formed of a plate 21, respectively 21', slidably mounted against the internal face of a side 121 or 122 of the frame 12. The plate 21 or 21 'is slidable in the length of the side 121 or 122, between two extreme positions. The plate 21 comprises at least one, and preferably two, slots 22 elongate in the longitudinal direction (of sliding) of the plate and of non-constant width. Preferably, each slot 22 has an oblong shape defining two circular orifices 222 and 224 respectively of a first diameter and a second diameter greater than the first, in the manner of a keyhole. To fix, slidably, the plate 21 or 21 'to the corresponding tube 121 or 122 of the frame, the latter comprises for example other oblong slots 24 of constant width and traversed by pins 26 protruding from the inner face of the corresponding tube of the frame. Finally, the element 2 or 2 'comprises an actuating handle in translation in the longitudinal direction of the side of the frame on which it is mounted. For example, this handle is formed of a plate 25, perpendicular to the plate 21 or 21 'and provided with at least one opening 251 gripping. The first element 2 or 2 'is intended to cooperate with a second element 3 (FIG. 2C) of the assembly mechanism, comprising at least one rod 31 movable in translation parallel to the panel and perpendicular to the plate 21 or 21' of the first element (therefore to the longitudinal direction of B11154 - stacking

8 side 121 or 122 corresponding). The rod 31 is intended to pass through the two uprights or crosspieces of two panels placed side by side and to cooperate with a slot 22 to block the panels to be assembled. For this, the rod comprises a head 312 having a diameter between the diameters of the orifices 222 and 224 defined by the light 22. In the embodiment shown, the head 312 is connected to the body 314 of the rod by a section 316 of diameter less than that of the orifice 222, the body 314 and the head 312 having approximately the same diameters. In a variant, the body of the rod has a diameter smaller than that of the orifice 222. Preferably, the second element 3 comprises at least two rods 31 carried by a longitudinal plate 32 intended to be arranged parallel to an internal face of a side 123 or 124 of the frame 1. A spring 33 (or other elastic return means) is interposed between the plate 32 and the frame, for example by being held by a centering pin 34 carried by the plate 32. The spring 33 improves the assembly by reminding the rods 31 towards the inside of the frame 1. The second element 3 also comprises a handle actuating in translation of the rod or rods 31, for example formed of a plate 35, perpendicular to the plate 32 and provided with at least one opening 351 gripping.

Each panel 1 comprises at least one element 2 (or 2 ') and at least one element 3 on opposite sides of the frame 12 (crosspieces or uprights). Thus, two panels placed end-to-end, for example stacked vertically, can be assembled temporarily.

In the preferred embodiment illustrated in FIG. 2, the panel 1 comprises two bolt-type elements 3 on two adjacent sides and two lock-type elements 2 on the other two sides. Thus, panels can be assembled laterally and vertically as shown in Figure 1.

B11154 - stacking

The difference between the elements 2 and 2 'lies in the length of the plate 21 or 21', the plate 21 'being longer than the plate 21. The element 2 comprises two slots 22 having the same spacing as the two rods 31 of the elements 3.

The element 2 'comprises, for example, six slots 22 distributed in the length and having two by two the same spacing as the two rods 31 of the elements 3. This provides an additional adjustment capacity in the arrangement of the panels. Preferably, the panels 1 are all arranged in the same direction, the element 2 defining for example the lower lock and the element 2 'the side lock. The sides 121 and 122 of the frame 12 comprise a number of through holes 26 corresponding to the number of lights of the element 2 or 2 '. The sides 123 and 124 receiving the elements 3 have through orifices 36 at least to slidably receive the rods 31. The assembly of panels to form a palisade is particularly simple. For example, a panel 1 is presented by its edge on that of a previous panel 1 and the upper bolts 3 of the lower panel are engaged and locked in the lower lock 2 of the upper panel. Laterally, a panel 1 is presented next to another and the side bolts 3 of one are engaged and locked in the side lock 2 'of the other.

The lower panels (closest to the ground) are preferably carried by feet 4 adjustable in height. Figure 3 is a perspective view of an embodiment of a foot module 4 of the palisade system. The foot comprises a base 42, intended to rest on the ground and carrying a plate 43 for receiving, for example, a lower cross 121 of a frame 12 of a panel. The plate 43 carries two rods 41, directed upwards, similar to the rods 31 of the bolts of the panels, that is to say having a body 414 separated from a head 412 by a section 416 of smaller diameter. The rods 41 are intended to cooperate B11154 - stacking

10 with the lower lock (item 2, Figure 2) of the panel 1 carried by the foot. The rods have a shorter length than the rods 31 insofar as they pass through only one tube of the frame.

The height of the plate 43 relative to the base 42 is adjustable. For example, the base carries a tube or vertical rod 44 on which is engaged a tube 45, integral and perpendicular to the plate 43. The bottom of the tube 44 is threaded to cooperate with a locking nut 46 to secure the position. Other means of height adjustment can be envisaged, for example by means of pins blocking the respective positions of the tubes 44 and 45. In the example shown, the plate 43 has a triangular shape, the two rods 41 and the tube 45 being distributed at the vertices of the triangle. This allows the tube 45 to escape the frame 12 when the panel is placed on the plate (see Figure 1). Alternatively, it will be possible to produce a plate 43 of generally rectangular shape with the rods 41 and the tube 45 aligned, the lower crossbar of the panels then having a central orifice (and the lock 2 an additional light) to receive the tube. Figure 4 is a perspective view of a bracing module 5 of the palisade. This module 5 has a general shape of bracket and has a vertical upright 51 at the upper end of which is mounted a horizontal branch 6. Preferably, the length of the horizontal branch 6 is adjustable. For this, it is formed of a tube 62 of rectangular section slidably mounted in a tube 52 of lower section fixed to the end of the upright 51. The tube 52 comprises for example regularly distributed orifices 522, one of which is intended for to receive a locking screw 622 provided on the tube 62. It may also provide a system of pins or other fastening means. The base 53 of the upright 51 is adapted to receive a height adjustment foot, for example, the lower part B11154 - stacking

11 (base 42, tube 44) of the foot of Figure 3. Alternatively, a height adjustment mechanism dedicated to the amount 51 is provided. The free end of the branch 6 carries a stirrup 64 intended to be assembled at the palisade. Preferably, this stirrup 64 is intended to grip two sections of tubes 121 or 123 of the frames 12 of the panels. These tubes then preferably comprise through holes 66 (FIG. 2) serving for the passage of pins 68 (FIG. 4) for blocking the stirrup. Once assembled, the module 5 not only provides a counter wind but also stiffens the assembly of the upper panels. Preferably, the upright 51 is adapted to receive weights 55 (FIG. 2) to ballast the bracing module. A bracing module as described above minimizes ground obstacles behind the palisade without affecting wind resistance. Preferably, the height of the bracing module 5 and the length of its branch 6 are such that a person can pass undisturbed.

Figure 5 is an exploded perspective view of an embodiment of an upper termination panel. This panel 9 has a structure similar to that of the panels 1. It comprises a frame 92, carrying a facing plate 94. The cross members of the frame have the same length as the width of the panels 1, so as to stack a panel 9 on the last panel 1 of the palisade. The bottom rail 95 of the panel 9 comprises a lower lock member 2 to cooperate with the upper bolts of the panel 1 on which it is placed. The lateral locking of the panels 9 between them is ensured, for example, by means of pins 96 to be engaged in the frame of the neighboring panel. Alternatively, an assembly mechanism similar to that described in relation with the panels 1 may be provided. As illustrated in FIG. 1, the stirrups 64 of the modules 5 enclose the crosspieces 95 of the panels 9 and the crosspieces 123 of the panels 1 higher. We can also B11154 - stacking

12 provide to dispense with panels 9 and, to use the same bracing module, provide a spacer having the same thickness as a tube. Fig. 6 is a perspective view of an embodiment of an angle module 7 for joining panels 1 (or 9) in a non-aligned manner. This module comprises tubular elements 72 and 74 of square section (of the same section as the tubes of the frames 12) connected to one another by one or more hinges 76 and 10 assembled to panels 1 (or 9 in a version less high) by a mechanism similar to that described in relation with FIGS. 2A to 2C. In other words, one of the elements, for example 72, comprises a lock element 2 and the other element, for example 74, comprises rods 41 constituting bolts capable of cooperating with the lateral lock element of FIG. A panel 1. The rods 41 are, as in the case of the feet 4, shorter than the rods 31 of the elements 3 insofar as a spring mechanism is not essential. In a variant, an element 3 is provided on element-side 74, provided that the hinge allows sufficient clearance for the actuation of the bolts. Preferably, the hinges 76 are adjustable. For example, each hinge is constituted by a tab 762 perpendicular to the axis of the tube 72 and carried by the latter, and 25 of a sector 763, carried by the tube 74 perpendicular to its axis. The tab 762 and the sector 763 are pivotally connected, for example by an axis 766 passing through orifices 726 and 746, respectively of the tab 762 and the sector 764. Furthermore, the sector 764 comprises, as shown, several orifices 768 along an arc of a circle is an arcuate light. Side tube 72, a retractable pin 764 is provided to pass through one of the orifices 768 to select the angle to give the module. Once this angle is set, the panels are connected to each side of the module using the assembly mechanisms.

The length of the corner modules is preferably equal to the height of the panels, a shorter corner module can be provided for the panels 9 of termination. If a door is desired in the palisade, a door module 8 is inserted into the structure. This module has dimensions preferably respecting the dimensions of the panels to integrate instead of one or two panels 1 in width. It comprises a frame 82 (Figure 1) provided with the same assembly mechanisms as those described in relation to Figures 2 and, within this frame, a door 84 with one or more flaps on hinges. Preferably, the door module is also equipped with bracing brackets 86 having shapes similar to those described in relation to FIG. 4.

As a particular embodiment, a modular partition system as described above can be realized with: panels 1 having the following dimensions: - length and width: about 1 m, - section of the frame tubes: about 5 cm; and bracing modules having the following dimensions: - length of the branch 62: about 85 cm; and - height of the amount 51: about 2 m.

The sections of the tubes of the different modules are preferably adapted to that of the panels 1. The materials used are preferably metallic and adapted to withstand external conditions. An advantage of the modular system described is that it is particularly simple to implement. A palisade can be mounted using these modular elements conferring a great freedom of arrangement of the space. It should be noted that different aspects of the modular system can be exploited separately in B11154 structures - stacking

14 palisade not containing all the characteristics of the system. This is the case, among others, the bracing module whose stem shape can be used on usual palisades and then provide the advantage of a free ground space, while offering good wind resistance. For example, a bracing module as described above can be sized so that the palisade (or panel) withstands force winds 7 on the Beaufort scale (62 km / h). Moreover, the structure of the panels, even with other modes of attachment, can help to achieve a fence with the help of stackable panels, thus facilitating handling. In particular, it is now possible to produce a construction hoard comprising at least two superposed panels, each panel having a supporting structure (its frame 12) or reinforcement distinct from that of the other panels, and the panels being assembled, by their slices, by connection structures between them.

In addition, the adjustable foot allows, associated with conventional panels, to enjoy a height adjustment effect. The angle module and more particularly its adjustable hinge allow a connection between conventional panels. Finally, the assembly mechanism of the panels can be transferred to various conventional modules and take back the advantages. Various embodiments have been described, various variations and modifications will be apparent to those skilled in the art. In particular, various details of system construction are apparent from the drawings without the need to be further described. In addition, the dimensions of the panels can be adapted to the constraints of handling, transport, storage, size of the partitions, etc. In addition, the number of panels for making a partition or a palisade is limited, neither in height nor in length. Finally, the practical implementation of the invention is B11154 - stacking

The scope of those skilled in the art from the functional indications given above.
