Description

The present invention relates to a device for forming a barrier and / or displaying a visual. It is known to use devices comprising a post to which are fixed one or more spool supports. On each of the coils is fixed an end of a band which tends to wrap around the coil under the action of return means. It is thus possible to unroll the band by pulling on its free end and let it wrap around the coil under the action of the spring. These known devices make it possible in particular to channel a pedestrian circulation flow, the unwound strip forming an obstacle, or display a visual printed on the tape in places with high traffic. However, the known devices can not be modified, in particular in size, height of positioning of the bands, in number of coil carriers, or in length or band width. They do not therefore prove to be perfectly adapted to all the situations in which they could be used. On the basis of this observation, a user is generally compelled to store several different devices, which he then uses according to his needs and the context by choosing the most suitable device. This can be expensive and inconvenient.

Also the present invention aims to remedy all or part of the disadvantages mentioned by proposing a modular device intended to form a barrier and / or display a visual whose characteristics (size, number of bands, positioning height of the bands, dimensions of the bands, distance between bands, visual tape, etc.) can be easily modified by a user, in order to adapt the device to the situation in which it is intended to be used. For this purpose, the subject of the present invention is a device intended to form a barrier and / or to display a visual, comprising support means capable of supporting the device, and a reel comprising a strip capable of being unwound to form a barrier and / or or display a visual, characterized in that the device further comprises: - first removable connection means, capable of removably connecting said reel and said support means, - at least one module, each module comprising a reel provided with a strip adapted to be unwound to form a barrier and / or display a visual, a pole provided with an upper end and a lower end, and second removable connection means, capable of releasably connecting the reel of each module and the upper end of the pole of the same module, - third removable connection means, capable of removably connecting the lower end of the pole of the u of one of the modules to the retractor connected to the support means and, when the device comprises a plurality of modules, capable of releasably connecting the lower end of the pole of each of the modules to the reel of a separate module. The device according to the invention thus offers the advantage of being modular and flexible. Thanks to the third removable connection means, which allow a removable connection of the modules together or on the support of the device, it is possible to adapt the latter to the circumstances of its use by adding a module or replacing one module with another ( comprising a different winder and / or a different pole). Thanks to the second detachable connection means, which allow the interior of the same module to removably link the winder and the pole of this module, it is allowed to modify a module by changing its winder by a different winder ( comprising a band of thickness or of different length for example) or by changing its pole by another having for example a different length. Thus, by way of examples, the number of reels, consequently the number of reels, the dimensions of these bands, the visual printed on these strips can be adapted to the circumstances of use of the device according to the invention. Similarly, the distance separating two consecutive bands depending on the length of the post separating the reels supporting these two bands, this distance is easily modifiable by substituting this post by another of different length.

According to another characteristic of the device according to the invention, the first removable connection means, the second removable connection means, and the third removable connection means each comprise a male part and a female part capable of cooperating with each other. other.

Thus, male part and female part are assembled and made integral with each other (in fact making two different modules or the reel and the pole of the same module) by simply inserting the male part into the part female and relative rotation of the one relative to the other by a predetermined fraction of a turn. Male part and female part become integral when the lugs are housed in the recesses provided for this purpose, resting under the sleeve. To separate the male part and the female part, a torque exerted in the opposite direction allows to extract the pins housing. It is then sufficient to slide them in the grooves of the sleeve to disassemble the male part of the female part or vice versa. According to another characteristic of the device according to the invention, the sleeve comprises a plurality of open grooves and the tenon comprises a plurality of radial lugs, each capable of sliding in one of the open grooves, each lug being also able to bear under the sleeve and being adapted to be housed in a recess formed under the sleeve when the post has been pivoted relative to the sleeve by a predetermined fraction of a turn, and in that one of the lugs is a positioning pin, and one of the grooves is a positioning groove, the positioning pin and the positioning groove having a thickness respectively different from that of the other pins and the other grooves, the thickness of the positioning pin and the groove of positioning being identical, in order to limit to a single position the number of possible relative positions of the sleeve and the post before their nesting. This feature has the advantage of allowing the unwinding of the strips of all the reels in a single plane, to form the different crosspieces of a barrier and / or display a visual with a reinforced effect increasing the visibility and the impact for an observer .

Advantageously, the tenon of the male part of the first connecting means and the tenon of the male part of each of the second removable connection means respectively belong to the casing of the retractor connected to the support means and to the casing of the reel. of each of the modules.

Figure 1 shows an example of device 1 according to the invention. The device 1 is intended to form a barrier and / or display a visual unwinding of one or more strips 2 each supported by a winder 3. The device 1 comprises support means, for example a base 5 and a post 6. The post 6 has an upper end 6a and a lower end 6b, the lower end 6b being fixed to the base 5. The length of the post 6 may be different from one device 1 to another, as can be seen in FIG. a device 1 whose post 6 is longer than that of the device shown in Figure 1. Alternatively, the support means may comprise a wall plate 4, visible in Figure 10, adapted to be fixed on a wall. The wall plate 4 comprises in particular a base 4a, and an upper cover 7 can be fixed on its upper part. The device 1 comprises first detachable connection means for removably fixing one of the reels 3 (the lowest vertically in the different figures) to the upper end 6a of the post 6 or to the wall plate 4. These first detachable connection means will be described in more detail below. Advantageously, the device 1 is modular. It comprises at least one module 8. Each module 8 comprises a winder 3, a pole 9 provided with an upper end 9a and a lower end 9b, and second removable connection means, which will be described in more detail below. after, to removably connect the winder 3 of each module 8 to the post 9 of the same module 8. In the example of Figure 1, the device 1 comprises a single module 8. The device 1 could include a plurality of modules 8, for example two as shown in Figure 11. The modules 8 may be different. The differences may relate to the length of their post 9, or the length, width or nature of the visual (color, message, figure, etc.) of the band 2 of their winder 3. The devices 1 shown on FIGS. 11 and 12 comprise, as examples, reels whose band has a thickness different from that of the strips of the reels of the device 1 represented in FIG. 1 (respectively 50 mm and 100 mm). It is thus possible to modulate the device 1 by modifying the number and / or the type of the modules 8 that it comprises, and for each module 8, by modifying its winding torque 3 - post 9.

The device 1 also comprises third removable connection means, which will be described in more detail below, for removably connecting the lower end 6b of one of the modules 8, or to the reel 3 linked to the pole 6 ( or to the wall plate 4), or to the winder 3 of a separate module 8. Indeed, when the device 1 comprises a plurality of modules 8, they are superimposed on each other, as can be seen in FIG. 11. According to the described embodiment of the device 1, each of the first, second and second third removable connection means comprise a male part and a female part intended to be inserted into one another. As shown in FIGS. 2 to 6 and 8 to 10, each female part comprises a hollow sleeve 11 and each male part comprises a post 12. The post 12 has dimensions enabling it to slide inside the hollow sleeve 11. . The sleeve 11 advantageously comprises a plurality of grooves 14 opening. The post 12 comprises a plurality of radial lugs 15, as well as grooves 14 formed by the sleeve 11. The grooves 14 are distributed over the contour of the sleeve 11 in a manner identical to the distribution of the radial lugs 15 on the post 12. In the example of the various figures, the tenons 12 each comprise four radial pins 15 uniformly distributed over the circumference of the post 12 to which they are attached. In a complementary manner, the sleeves 11 each comprise four grooves 14 opening on either side, the four grooves 14 also being evenly distributed on the inner wall of the sleeve 11 to which they belong. In order to secure a stud 12 with a sleeve 11, thus a male part with a female part, the radial lugs 15 of each stud 12 are capable of sliding inside the grooves 14 of each sleeve 11.

Each male part comprises a base 17, visible for example in Figure 4. Each sleeve 11 has a first bearing surface 11a and a second bearing surface 11b. The dimensions of the studs 12 and the sleeves 11 are such that when this base 17 abuts against the first upper bearing surface 11a of the sleeve 11, the radial lugs 15 open grooves 14. When the stud 12 is pivoted relative to the sleeve 11, the lugs 15 of the stud 12 abut against the second bearing surface 11b below the sleeve 11, as can be seen in FIG. 3, for example. The second bearing surface 11b is not parallel to the first bearing surface 11a. The second bearing surface 11b presents, from the mouth of each groove 14, an increasing slope to a recess 11c, as can be seen in FIGS. 13 and 14. Thus, once the post 12 has been inserted into the sleeve 11 and the lugs 15 having opened grooves 14, the pivoting of the pin 12 relative to the sleeve 11 causes the sliding of the lugs 15 under the sleeve 11, against its second bearing surface 11b. Due to the increasing slope of the second bearing surface 11b, this has the effect of clamping the base 17 against the first bearing surface 11a. Once the pin 12 pivoted by a predetermined fraction of a turn relative to the sleeve 11, the lugs 15 are housed in the recesses 11 c uniformly distributed on the second bearing surface 11 b. The stud 12 (the male part) and the sleeve 11 (the female part) are thus held in position relative to one another. The application of a torque between the post 12 and the sleeve 11 allows them to be detached, the lugs 15 leaving the recesses 11c made on the second bearing surface 11b. By turning the post 12 by a predetermined fraction of a turn relative to the sleeve 11, in the opposite direction this time, the lugs 15 slide again under the sleeve 11, on its second bearing surface 11b until reaching the Mouth of the grooves 14. The removal of the post 11 is then effected by sliding the lugs 15 in the grooves 14. Advantageously, each post 12 comprises a lug 19 said positioning. This lug 19 merges with one of the radial lugs of the post 12. This lug 19 has the particularity of having a different width than the other radial lugs 15, as can be seen in Figure 4 for example. In a complementary manner, and as illustrated in FIG. 9, the sleeve 11 advantageously comprises a positioning groove 20. The positioning groove 20 coincides with one of the grooves 14 of the sleeve 12. However, the positioning groove 20 has a width different from that of the other grooves 14. The width of the positioning groove 20 is identical to that of the groove 14. 19 positioning pin.

Thus, the positioning pin 19 and the positioning groove 20 must necessarily slide one inside the other to allow the assembly of each pin 12 and each sleeve 11. This requires a unique positioning of the pin 12 relative to the sleeve 11 before assembly. This ensures, when assembling a reel 3 on a pole 9 or a module 8 on another module 8, to ensure the alignment of all the strips 2 of the device 1. These bands 2 can be rolled out in one and the same plane, to reinforce the barrier effect or enhance the visual effect created when they are unwound. In the embodiment of the various figures, the tenon 12 of the male part of the first connecting means, connecting one of the reels 3 to the post 6 or to the wall plate 4, belongs to the housing 22 (visible in FIG. 6) of this 3. It forms with the housing 22 a single piece, obtained for example by molding. The sleeve 11 of the female part of the first removable connection means belongs to the support means. When the support means comprise the base 5 and the post 6, the sleeve 11 of the female part of the first removable connection means is fixed, for example by means of screws, to the upper end 6a of the post 6 and extends at least partially within it. When the support means comprise a wall plate 4, the sleeve 11 of the first removable connection means may belong to the base 4a of the wall plate 4 and form with this base 4a one and the same piece. The post 12 of the male part of each of the second removable connection means, connecting the reel 3 and the post 9 of the same module 8, belongs to the housing 22 of the reel 3 of each module 8. form with the housing 22 of the winder 3 of a module 8 a single piece, obtained for example by molding. As shown in FIG. 8, the sleeve 11 of the female part of each of the second removable connection means is fastened to the upper end 9a of each post 9, for example by screws, and extends at least partially inside the pole 9. Concerning the third removable connection means, for connecting the lower end 9b of the pole 9 of a module 8 to the winder 3 connected to the pole 6 or to the winder 3 of a 8 distinct module, the pin 12 of the male part belongs to a cover 24, visible in Figure 5. This cover 24 is intended to be fixed on the upper part of the housing 22 of the winder 3 which will support the module 8, by example using screws. As shown in FIG. 8, the sleeve 11 of the female part of the third removable connecting means is fixed on the lower end 9a of each post 9, for example by screws, and extends at least partially to the 9. Each post 9, and optionally the post 6, is advantageously hollow, and may be made of light metal alloy, for example an aluminum alloy. Each post 9, and if necessary the post 6, may have a cylindrical section, as is the case in the various figures. Each winder 3 comprises the housing 22, visible in FIG. 6, in the form of a cylindrical box open on the top and being able to be closed by a cover 23 or the cover 24. The cover 23 does not have a pin 12, as is for example shown in Figure 2, and is intended to equip the retractor 3 located vertically higher than all other reels 3 of the device 1. The other reels 3 of the device 1 comprise a housing 22 closed by the cover 24 provided with 12, which allows them to be fastened to the lower end 9b of a post 9. As shown in FIG. 3, the housing 22 contains a coil 25. As can be seen in FIG. it is provided with a slot 25a. The coil 25 is connected to the housing 22 by a pivot connection. The slot 25a is traversed by one of the strips 2 of the device 1. Each strip 2 has an end 2a provided with a stop 26 and a free end 2b also provided with a stop 27 adapted to cooperate with a fastening member 28. A band 2 may have for example a width of the order of 5 cm or 10 cm. On its outer face, the housing 22 of each winder 3 may comprise protrusions 30 forming one or more grooves. This groove or these grooves have a shape complementary to that of the fastening member 28 so that the latter can be inserted therein. This or these grooves thus realize sliding links held between the fastening member of a first device 1 and the housing 22 of one of the reels 3 of a second device 1. The groove or grooves formed by the excrescences For example, they may be T-shaped or dovetailed. The coil 25 of each winder 3 is also connected to one end of a spiral spring 32, as shown in Figure 3, housed in the cover 23 or cover 24, if appropriate. The other end of this spiral spring 32 is connected to the cover 23 (or hood 24) in which it is housed.

The strips 2 may for example have a length of 3 m or 5 m or more. To adapt a winder 3 comprising a spool 25 to which is connected a strip 2 of length of length 3 m, so as to obtain a winder whose strip 2 has a length of 5 m, while maintaining the same spring 32 spiral, a The solution consists in modifying the diameter of the coil 25 (by enlarging it) and connecting it to a strip 2 of length 5 m and of less thickness than the strip 2 of length 3 m. Indeed, thanks to the enlarged diameter of the coil 25, a turn of this coil 25 allows to unroll a strip length 2 greater than that which could have been unwound with a revolution of the unmodified coil 25. Finally, the number of turns made by the coil 25 remains unchanged, that the strip 2 has a length of 3 m or 5 m, provided that the diameter of the coil 25 has been adapted. It is thus possible to use a band 2 of 5 m (for example) rather than 3 m, without changing the spring 32 spiral.

Thus, the device 1 according to the invention is modular and flexible. It makes it possible to vary the number of reels 3 (thus of strips 2) by adding or removing modules 8. It makes it possible to choose the height of the reels 3, by choosing posts 9 of predetermined length. It makes it possible to vary the length of the strips 2, their width, the visual which is printed there. Although this is not shown in the various figures, it is thus possible thanks to the device 1, to combine for example a winder 3 having a band 2 of width 5 cm with a winder 3 having a band 2 of width equal to 10 cm, depending on the desired effect.

Of course, the invention is not limited to the embodiment described above, this embodiment having been given as an example. Modifications are possible, in particular from the point of view of the constitution of the various elements or by the substitution of technical equivalents, without departing from the scope of protection of the invention.
