Description

The invention relates to a device for the storage and implementation of a banner comprising a banner capable of being deployed between two posts, at least one storage box on at least one of said posts, said box for sheltering said streamer in the folded position and means for securing said streamer in the deployed position with said posts.

Such a device will find, for example, an application in the field of temporary traffic signaling devices for securing traffic areas, and in which the signaling streamers are conventionally used to condemn a temporarily impassable road, for example because of work in progress. , floods, the presence of heavy ice, due to untimely traffic jams, etc.

Of course, other applications of the device according to the invention can be envisaged, such as in particular the display of banners for advertising purposes or advertising promotions, for example deployed in the heart of commercial areas.

The temporary aspect requires having an easy installation device and fast use where the deployment and folding of the streamer is as simple as possible.

In addition, such signaling streamers being of temporary use, it is necessary to have a means to store them and keep them safe between two consecutive uses. Indeed, when the banners are not used, they must be protected from possible damage due to bad weather but also make them inaccessible to unauthorized users.

As already indicated above, the known devices for the storage and implementation of a banner conventionally comprise two posts, intended to be placed for example of on both sides of a road, where appropriate. These two poles each allow the attachment of one end of the streamer in its deployed position. These posts can also be surmounted by storage boxes for storing a signal streamer in the folded position, for example when access to the road is allowed.

The storage boxes of known devices have the disadvantage of involving a tedious storage of the streamer, requiring rigor on the part of the user to fold it properly. However, for lack of time, the operator does not often bother to carefully fold the banner and just introduce it somehow into the storage box where it ends up stored more or less ball, often wet or stained with mud. Such a method of proceeding leads to a less long-term embrittlement and then inadvertent degradation of the streamers stored in the storage boxes above the posts known devices for storage and implementation of a streamer. Thus, it is regularly necessary to replace degraded streamers, which implies significant additional costs. Simplifying the folding of the streamer within the storage boxes is thus necessary both to be fast and efficient but also to extend the life of such a streamer.

In addition, apart from facilitating the folding of the streamer, it is also essential that its deployment is easy, fast even in the event of extreme weather events, such as a strong wind or heavy rain. Then, it is essential to have a reliable and secure device in which the banner once in its deployed position durably withstands the stresses encountered, including wind gusts of 200km / h, as required by the regulations concerning road safety. Indeed, the streamers must withstand pulling, not only to condemn the pavement for as long as necessary, but also to prevent it from impacting possible vehicles, putting their passengers at risk.

However, the problem of most streamers of the state of the art lies in the fact that they do not withstand severe weather, such as violent wind, hail, torrent of rain, etc. It has been found with the devices of the state of the art, such as in particular those known publications US 2007/0176158 and DE 23 29 930 , that the streamers could unhook themselves from their means of fixation in case of bad weather and thus not to fulfill their role with the users.

To avoid this, several attachment systems exist, but most are expensive to manufacture and complicated to implement by users. In addition, they often have to deploy these streamers in an emergency, very quickly and in difficult climatic conditions, which further accentuates the painful nature of the installation of the banner across the passage that is to be denied access.

Finally, it was also found that during its deployment, a signaling banner of a device for storing and implementing a banner of the prior art often hangs on the ground for a time. Indeed, operators usually working alone, and in sometimes extreme weather conditions, can not always provide the significant effort required for the deployment of a banner with a large footprint and weight. Therefore, such a procedure, wherein the streamer, once extracted from its storage box located at a first attachment pole, is gradually unfolded and transported to the second hanging pole being dragged on along the ground, inevitably leads to an untimely wear of said streamer, requiring its frequent replacement and thus again untimely costs.

The present invention aims to overcome the disadvantages of the prior art by proposing a device for the storage and implementation of a streamer of simple structure, allowing both deployment and easy folding of the banner by an operator working alone and ensuring a better resistance of the latter to the stresses undergone, especially environmental, so as to improve both the durability of the device in use and the banner over time.

For this purpose the invention relates to a device for storing and implementing a streamer, as claimed in independent claim 1, comprising at least one tension-locking means of said streamer in the deployed position.

This tension blocking means allows the streamer in the deployed position to maintain sufficient tension to withstand the weather without falling off the posts. Said storage box houses a way of unwinding and winding of said streamer to bring it from its folded position to its deployed position and vice versa. This unwinding and winding means comprises a shaft on which a lateral end of the streamer is fixed, said shaft being mounted in rotation about an axis connected to said storage box, said axis being parallel to the longitudinal axis of the pole on which is located the storage chest.

Furthermore, said axis is pivotally mounted relative to said storage box between a unwinding position of the streamer in which it is parallel to the longitudinal axis of the pole on which the storage box is located and a winding position of the streamer in which it is perpendicular to said longitudinal axis of said post.

Another advantageous characteristic of the invention is further defined by the fact that said shaft comprises means for braking its rotation about said axis, said braking means being active when said axis is placed parallel to the longitudinal axis of the pole and inactive. when said axis is placed perpendicularly to the longitudinal axis of the pole.

On the other hand, said tree may also include at each with its ends a flange for guiding the streamer around the shaft during winding, one of said flanges may include a handle for manual rotation of the shaft about its axis.

Another feature of the invention is further defined by the fact that the streamer is provided at each of its lateral ends with at least one means for fixing a first end of a strap or a first end of a strap. tie with shackle.

The fixing means may consist of an orifice bordered by an eyelet.

An additional feature of the invention is represented by the fact that the second end of the strap is able to cooperate with the means for locking the tension of the streamer in the deployed position while a second end of the tie is able to cooperate with the securing means of said deployed banner with said posts.

Advantageously, the tension locking means of the streamer and the securing means can be fixed inside the storage box.

The present device is further characterized in that said securing means consist of at least one hook, while said tension blocking means consist of at least one ratchet tensioner.

Another feature of the invention is defined by the fact that said strap and / or the shackle connection comprises (s) means for adjusting its (their) length.

On the other hand, said storage box has a bottom surmounted by a peripheral wall delimiting its internal volume and covered by an upper wall, said peripheral wall comprising an access door to said internal volume.

Advantageously, said storage box may include means for locking the door in the closed position.

Another advantageous characteristic of the invention is further defined by the fact that the free side edge of the door is provided with at least one cutout facing the one or more securing means or the tension locking means or means. in the closed position of the door.

Advantageously, the bottom of the storage box may comprise at least one opening for the flow of fluids, while at least a portion of its peripheral wall or of its upper wall may comprise at least one ventilation opening.

The present invention relates to a device 1 for the storage and implementation of a streamer 2. As indicated in the preamble, the device 1 is suitable for different applications, and will be described hereinafter, by way of example only, in the framework of a use to block a passage. Said passage may be for example a road, the entrance of a place, a gantry of a toll, etc.

The device 1 according to the invention comprises a streamer 2, such as in particular a signaling banner of a message to the users of the passage. For example, stream 2 may signal a hazard such as a flood or accident, the closure of the access road, or prohibit access to an area due to work in progress or sporting events.

In the embodiment shown, the streamer 2 has a rectangular shape in which it has two opposite lateral ends 20, 21 and two longitudinal ends 22, 23 opposite perpendicular to the lateral ends 20, 21. The streamer 2 may be made of a material PVC, preferably anti-fungicide, covered with a retro-reflective class II film meeting road safety standards.

During its use, in order to fulfill its role of signaling and blocking the passage, the streamer 2 is deployed and hooked by each of its lateral ends 20, 21 on two posts 3 positioned, using ground anchoring means reversible or not respectively on either side of the passage to be barred.

In the illustrated embodiment, the posts 3 have a tubular shape of ovoid section. They comprise a bottom 30 surmounted by a peripheral wall 31 and an upper wall 32 parallel to said bottom 30. At least part of their internal volume defines a storage box 4 for the streamer 2 in its folded position.

The internal volume of the post 3, and therefore of the storage box 4, is accessible by means of a door 5 of the post 3 which can be opened or closed by means of any locking means 6 known to the man of the occupation, such as for example a triangle lock. The locking means advantageously makes it possible to limit the access to the storage box 4 only to authorized users, holders of an unlocking means.

According to the invention, the storage box 4 comprises a shaft 7, defined by a metal tube, rotatably mounted on an axis 71 preferably of square section, fixed on a shelf 40 that includes the storage box 4. The axis 71 is longer than the shaft 7 and therefore has two ends 25, 26 which emerge respectively on each side of the tube defining the shaft 7.

The shaft 7, a lateral end 20, 21 of the streamer 2 is secured, is thus rotatable about the axis 71 in one direction or another as indicated by the arrows F1 , F2, so as to cause the streamer 2 from its folded position to its deployed position and vice versa from its deployed position to its folded position. The shaft 7, rotating about the axis 71, has the advantage of facilitating the deployment but also the folding of the streamer 2 and therefore allows to store it carefully in the trunk 4, without it being in a ball nor does it present unwanted folds.

In the embodiment shown, the shaft 71 of the shaft 7 is pivotally mounted on a spacer 73, having a section substantially in "Ω", fixed on the shelf 40 of the storage box 4. In fact, the end 25 of the shaft 71 is connected to a rod 76 perpendicular to said axis 71 and whose free ends 12, 13 are respectively received in a hole 79 formed on each of the lateral wings 14, 15 of the spacer 73. The axis 71 is thus pivotable relative to the spacer 73 between a position in which it is parallel to the longitudinal axis of the pole 3, and thus vertical, and a position in which it is perpendicular to the longitudinal axis of the pole 3 and therefore horizontal.

Advantageously, the axis 71 of the shaft 7 is placed in the vertical position, when the streamer 2 is not used and is wound around the shaft 7. This is then fully received in the storage box 4, the door 5 can be closed and the lock locked to prevent access to the streamer 2.

When the operator wishes to deploy the streamer 2, it is sufficient for him to open the door 5, after having unlocked it, then to manually pull on the lateral end 20, 21 free of the streamer 2 wrapped around a shaft 7 housed in the storage box 4 of one of the posts 3, then to move gradually to the second post 3 where it will proceed to the attachment of said free lateral end 20, 21 of the streamer 2, by means of cables 10b or straps 10a as will be described below.

According to another specificity of the invention, the device comprises a means of braking 74 of the rotation of the shaft 7 about the axis 71. This braking means comprises a spring 74, defined by a cylindrical sleeve of engaged elastomeric material around the end 25 of the axis 71 connected to the spacer 73. In the vertical position of the shaft 7, the spring 74 is compressed (cf. Fig. 3 ) between the upper face 20 of the spacer 73 and a pin 27 passing through the other end 26 of the axis 71. The cylindrical sleeve defining the spring 74 is then convex generating friction between the shaft 7, the pin 27 and the spring 74 materializing by a braking of the rotation of the shaft 7 about the axis 71.

Advantageously, the spring 74 is active only when the axis 71 of the shaft 7 is placed in its vertical position. In this way, when the user proceeds with the deployment of the streamer 2, the unfolding of the latter with respect to the shaft 7 is controlled and slowed, which prevents the streamer 2 from unfolding itself or too quickly and falling on the ground under the effect of its simple weight. This allows an operator to work alone by providing less effort while controlling the progress of the streamer 2 which is less likely to fall to the ground and is therefore better preserved from any damage.

In fact, the spacer 73 has a structure in which the distance d1, between its upper face 24 and the holes 79 of each of its wings 14, 15, is greater than the distance d2 between said holes 79 and the front edge. 80 of each of the wings 14, 15 (cf. Fig. 6 ). Thus, when the shaft 7 is placed in its horizontal position, the elastomeric sleeve defining the spring 74 is no longer in contact with the spacer 73, is therefore no longer compressed and no longer exerts friction on the shaft 7 whose rotation is then no longer braked.

On the other hand, the rod 76 is connected to an indexing finger 81 (cf. Fig. 3B ) perpendicular to said rod 76. In the vertical position of the shaft 7, the indexing finger 81 is able to be locked in position relative to the spacer 73 by a reversible locking means (not shown). This avoids inadvertent pivoting of the shaft 7 to its horizontal position during the unwinding of the streamer 2 under the effect of a possible excessive traction exerted by the operator.

With reference to the figure 1 each angle 16, 17, 18, 19 of the streamer 2 comprises an orifice bordered by an eyelet 8. The eyelets 8 make it possible to secure to the streamer 2 a first end of each of two straps 10a or of each of two cables 10b, the other end of each strap 10a and each cable 10b cooperating with one of said posts 3.

According to a particular embodiment, said shaft 7 comprises lugs 82 able to cooperate with the eyelets 8 of the streamer 2 which allows, as indicated above, the attachment of a lateral end 20, 21 of the streamer 2 with the shaft 7, so as to prevent this side of the streamer 2, not maintained by the operator as it unfolds, falls to the ground during the full deployment of the streamer 2.

According to the invention, each cable 10b has, on its end opposite to that which cooperates with an eyelet 8, at least one end in the form of a shackle adapted to cooperate with a hook 9, suitably fastened inside the trunk of the trunk. 4. For this purpose, each storage box 4 has two coaxial hooks 9.

The shackle cables 10b represent the intermediate connection between the eyelet 8 at an angle of the streamer 2 and a hook 9 of the storage box 4. As a result, the shackle links 10b allow the fixation of the streamer 2 to a pole 3.

According to a particular characteristic of the invention, each strap 10a is connected by a first end to an eyelet 8 of the streamer 2 and by its second end to a ratchet 11 attached to the wall inside the storage box 4 3. The two ratchet tensioners 11 are aligned near the opening of the storage box 4. Each ratchet 11 makes it possible to tension the straps 10a previously connected to the streamer 2 by means of the eyelets 8. .

In fact, after proceeding to the full deployment of the streamer 2, the operator hangs the latter, as indicated above, the second post 3 located opposite the one with the shaft 7 on which the streamer 2 was wound. It uses for this purpose two straps 10a or two cables with shackle 10b respectively cooperating with the eyelets 8 of the streamer 2 and the hooks 9 or ratchet tensioners 11 of the storage compartment 4 of the second pole 3. It then returns to the level of the shaft 7 to which a lateral end 20, 21 of the streamer 2 is still connected, through two straps 10a or two cables 10b, or directly through the lugs of the shaft 7. The operator can then unhook this lateral end 20, 21 of the streamer 2 of the shaft 7, that is to say separate the straps 10a or cables 10b of the shaft 7 and then hang the free end of the straps 10a or the free end of the shackle cables 10b respectively on a ratchet 11 or a hook 9 of the storage box 4 of the pole housing the shaft 7 on which the streamer was wound. The operator then proceeds to power up the streamer 2 by means of the ratchet tensioners 11.

Advantageously, as indicated on the figure 1 , the spacing e between the two coaxial hooks 9 and the spacing e between the two ratchet tensioners 11 is greater than the distance d between the two eyelets 8 that has the same lateral end 20, 21 of the streamer 2. It results in a vertical tension applied to each of the sides of the streamer 2 and therefore a perfect wind resistance of the latter.

According to a specific embodiment, the straps 10b and / or the cables 10a with shackle comprise means for adjusting their length which allows to center the streamer 2 deployed and hooked between the two posts 3 with respect to the roadway to be blocked.

On the other hand, the access door 5 to the storage box 4, has on its free edge two cutouts 51 each located vis-à-vis the hooks or 9 or ratchet or 11 of the trunk of the trunk 4. In this way, the passage of the straps 10b or links 10a connected to said hooks 9 or audits tensioner 11 is possible through the cutouts 51 of the access door 5 even when it is closed, which avoids their pinching or even tearing them.

This also allows the access door 5 to be properly closed even when the streamer 2 is in the deployed position between the two posts 3.

According to another characteristic of the invention, the shaft 7 comprises a perforated flange 75 at each of its ends, which defines the winding area of the streamer 2 around the shaft 7. Advantageously, said flanges 75 of positioning are perforated by openings 751 through any shape that allow the flow of water which can be impregnated the streamer 2 when it has been subjected to rain, after it is folded into the storage box 4. One of the two flanges 75 further comprises a handle 72 for manually performing the rotation of the shaft 7 about the axis 71, especially when it is placed in a horizontal position.

When the operator wishes to wind the streamer 2 around the shaft 7, in order to store it after use, he places said shaft 7 in a horizontal position by pivoting the shaft 71 around the spacer 73 after having unlocked the indexing finger 81. In this horizontal position of the shaft 7, the braking means 74 is inactive as previously described. In this way, when the operator wishes to wind the streamer 2 around the shaft 7 to store it in the trunk 4, the rotation of the shaft 7 about the axis 71 is not braked, and it suffices to the operator to turn the handle 72 to perform the winding of the streamer 2 around the shaft 7, after detaching the straps 10b or the cables 10a of the two posts 3 and connected a lateral side of the streamer 2 to the tree 7.

Advantageously, the bottom 30 of the storage box 4 comprises a fluid flow grid 77. Said flow gate 77 avoids storage within the storage box 4 residual liquids from the streamer 2 possibly exposed to rain. Consequently, the presence of the grid 77 makes it possible to prevent the mildew of the streamer 2 which is in the confined volume of the box 4 after its storage.

Also advantageously, the storage box 4 is provided with a ventilation grid 78 at its upper wall 32 for drying the streamer 2 when it is wet.

Thus, the presence of the ventilation grids 78 and flow 77 make it possible to avoid confining the volume in which the streamer 2 is folded, that is to say that these grids prevent the deterioration of the streamer 2 by mold and slow down its wear over time.

It can also be provided to equip one of the posts 3 with a water level sensor (not shown), arranged appropriately, and able to immediately detect a rise of water requiring the securing of the roadway and to block the passage on either side of which the posts 3 are installed, and therefore a deployment of the streamer 2. Such a water level sensor is classically able to send an alert to a monitoring center in connection with the services. Roadside equipment in charge of the implementation of the banner 2. These can be very quickly informed of the need to intervene, and can, if necessary, act without waiting for the order of the prefecture. Conversely, such a water level sensor also allows to detect a drop of water sufficient to allow the storage of the streamer 2 inside its storage compartment 4, and the practicability of the roadway.
