Description

1 RETRACTABLE SHELTER

  The invention relates to a new retractable shelter, more particularly intended for enclosures and other premises located outside.

  There are many applications to such outdoor premises: storage of salt in winter, intended to be spread on the roads, storage of grain, silo, etc.

  In each of these different applications, it is necessary to use loading or unloading vehicles of the tractor, backhoe type, etc. so that, if one does not wish to carry out too expensive civil engineering structures , said structures

  are of low height, made of a light material, often prohibiting the presence of a permanent roof to precisely allow the movement of these machines.

  In fact, it is very often observed that the salt storage places do not have a roof or shelter, capable of sheltering them from the weather. In doing so, taking into account these bad weather conditions, we observe a runoff of salt, which in addition to the wastage of material, also generates local pollution since by runoff, this salt reaches streams and other rivers.20 The object of this invention is to overcome these various drawbacks by proposing a sheltering structure, retractable, easy to implement and install, including in already existing premises, and nevertheless having relatively high mechanical strengths to cope with the climatic conditions that the we meet

habitually.

  This retractable shelter is characterized in that it comprises a plurality of elementary modules of arcuate shape, capable of moving in translation between two extreme positions: at a first retracted position, in which all of said elementary modules are gathered under the module the most concentrically external, most often fixed, thus freeing access to the place of installation of the shelter, * and a second developed position, in which each of the mobile elementary modules is moved in rectilinear translation according to a determined stroke , of

  telescopically, so as to completely shelter said place.

  In other words, the invention consists in providing the storage places in question with a telescopic shelter, allowing, as and when the consumption of the stored material,

  to discover at will said place.

  According to a characteristic of the invention, the elementary modules consist of a metal frame, generally made of aluminum, integrating panels,

  in particular transparent, such as glass or plastic panels, for example made of polymethacrylate or polycarbonate, the lateral ends of said chassis 5 being provided with rollers, in order to allow the rectilinear translation of said modules, these rollers advantageously being mounted on ball bearings .

  According to an advantageous characteristic of the invention, these rollers, mounted to rotate freely, are located in the plane of the terminal area of each of said modules

elementary.

  According to another characteristic of the invention, the shelter comprises at least two load-bearing metal structures, respectively attached to the upper end of the walls of the enclosure to be sheltered, each of these load-bearing structures adopting a substantially triangular profile and having a plurality bearing plates, regularly distributed, at least one of the lateral faces of which is provided with an equal number of cutouts

  substantially homothetic with respect to each other, each of these cutouts being intended to receive a guide rail for the elementary modules, inserted at the level of said cutouts by simple sliding, and at the level of which are intended to come and roll the 20 rollers of which are equipped with the elementary modules.

  The invention also relates to the multiple parallel shelters, which in this case are provided for n parallel shelters with n + 1 load-bearing structures, the plates of each of the intermediate load-bearing structures, then having two faces each provided with

  cutouts for receiving the guide rails.

  The manner in which the invention can be implemented and the advantages which result therefrom will emerge more clearly from the following exemplary embodiments, given for information only and

  limiting in support of the appended figures.

  Figure 4 is a view similar to Figure 3, of another embodiment.

  Figure 5 is a schematic representation of such a support structure provided with

  Figure 6 is a schematic representation in cross section of the profiled elements constituting the frame of the shelter according to the invention.

  We have described in connection with Figure 1 a schematic representation in side view of a telescopic shelter according to the invention. This shelter has been represented according to its developed configuration.

  This shelter is intended, in the present case, to cover a place of storage of salt with a view to its next spreading at the level of roads in prevention of ice or snow.

  This shelter rests on the upper end of the walls (1) defining said room. In this example, it consists of four elementary modules, respectively (2), (3), (4) and (5), of arcuate shape, as can be observed, the modules (2) being the more external, and capable of receiving, by sliding, the other three modules, so as to

  adopt the retracted configuration.

  Each of these elementary modules consists of an aluminum frame (22), giving it an arched or curved shape. This chassis receives a plate (23), of the same configuration, made of polymethyl methacrylate, or of alveolar polycarbonate. These plates are advantageously anti-UV treated. FIG. 6 shows a cross-sectional view of the sections constituting this chassis. This profile has at its upper part a protrusion (27) after spinning, having two lateral projections (30) directed towards the side faces (33, 34) of said profile. In addition, each of said lateral faces (33, 34) also extends towards the upper part by a shoulder (35), on which the plate (23) bears. The latter is held in place, without reaching the area of the projection (27) by means of a clamping member (28), which is fixed by clipping by means of lugs (31) on said projection (27). This clamping member, for example made of plastic, therefore has a certain elasticity, allowing the partial spacing of the end of the legs (31), so as to allow the cooperation of the projections (32) with which they are provided. near their free end with the lateral projections (30) of the projection (27). In addition, when required, an annular seal (29) can be placed between the upper face of the plate (23) and the clamping member.

  (28), as can be seen in Figure 6.

  In addition, in order to reinforce the mechanical resistance of these plates, and more generally of the assembly, straps (24) made of stainless steel strip are also used, and extend from a lateral edge to the other of each of these elementary modules, according to a director of said modules. In the example described, each of the modules has two straps (24). As can be seen in FIG. 5, first of all, the outermost element (2) is fixed and is fixed at the level of a support structure (7), described in more detail later, by welding. On the other hand, the other modules (3), (4) and (5) are provided at their lateral ends with a plurality of rollers (20), mounted idly in rotation, and intended

  to be supported on a guide rail (21), the mounting of which will also be described in more detail later.

  More specifically, the shape of the roller (20) is complementary to that of the guide rail (21), in order to optimize the fixing and the free translation of each of the modules.

  elementary at the level of the supporting structure (7).

  In addition, and also in order to optimize the fixing of the elementary modules at the level of the support structure (7), each of the elementary modules is provided with a metal tab (24), the curved end of which (25) slides. under the head of the rail (21), as can be seen in FIG. 5. In this way, without in any way altering the free translation of the elementary module at the level of the rail in question, this tab secures the fixing of said module in the event of severe weather, in particular in the event of

  gusts of wind, thus aiming to prohibit the withdrawal of said module from the rail.

  The supporting structure (7) will now be described in more detail.

characteristic of the invention.

  This support structure (7), as can be seen in Figures 3 and 4, consists of a plurality of metal plates (7), of triangular shape, connected together by means of spacers also made steel (not shown). The assembly thus formed by mechanical welding, is relatively light and easy to set up at

  the end of a wall of an already existing room.

  Each of these triangular plates (7) is fixed to the upper end of the wall at the level of which it is intended to be implanted, by means of angles, planted in the mass of the wall, and coming to be inserted in the through lights (9 ) and (10), arranged at

  level of the base (8) of said plates (7).

  In addition, at least one of the faces (10, 11) other than the base (8) of each of the triangular plates (7) is provided with a plurality of through cutouts (12 - 14),

  in particular carried out by laser, substantially equal to each other and homothetic to each other, that is to say that they have relatively the same orientation, as well as 5, as can be seen in FIGS. 3 and 4 .

  These cutouts (12 - 14) substantially T-shaped, are intended to receive the guide rails (21) mentioned above. This rail is inserted by simple sliding into the upper part of the T, as can easily be seen in connection with FIGS. 3, 4 and 5. In fact, prior to this insertion, a T-shaped rail support ( 36), made of steel laminate, is put in place and welded to the corresponding location of the cutouts at each of the plates (7). This short support, as well as the rail (21) over the entire length of the support structure, further constituting a support for the rails

  (21), also a reinforcing element for said structure.

  In fact, the head (19) of said rails (21) is intended to protrude from the respective cutout, so as to allow interaction between said head and the rollers (20) of the

  elementary modules and with the end (25) of the securing tab (24).

  The rails (21) are advantageously made of aluminum. They are put in place on the support structure once it has been produced by insertion at one of the ends of the latter. Taking into account the cutouts with which the triangular plates which constitute them are provided, this insertion is easy, said rails sliding at the level of these cutouts on the T-shaped supports (36). The rails are fixed at the cutouts by the intrinsic shape of the cutouts. The relative immobilization of the rails in the longitudinal direction is carried out by crimping the upper part of the cutouts, constituting crimping spouts (37) by simple deformation (hammer), directly on site,

  allowing the longitudinal adjustment of the rails.

  The three mobile modules (3 - 5) are therefore able to perform a rectilinear translation, in order to pass from a retracted configuration, in which they are located under the fixed module (2), and this concentrically, to a developed configuration, telescopically, the travel of the module (3) being substantially limited to its sole length, that of the module (4) to approximately twice its length, and finally that of the module (5) to approximately three times its length, near partial overlap areas, intended to ensure a certain seal in the shelter thus formed. It is also possible to install

  sealing brushes (38), the profiles (22) being grooved (26) for this purpose.

  In the context of multiple shelters parallel to each other, therefore comprising load-bearing walls parallel to each other, the support structure (7) can then become multiple, such that

  corresponding to the embodiment described in FIG. 4. In this case, the two faces (10) and (11) of each of the triangular plates (7), other than the base (8) are each provided with through-holes ( 12 - 14), each intended to receive a guide rail (21), as can be seen in FIG. 5.

  Furthermore, in the embodiment shown in FIG. 4, the base (8) of each of the triangular plates (7) of the support structure extends downward along

  two feet (17) and (18), in order to better surround the retaining wall and this, with a view to optimizing the fixing of the supporting structure at the level of this wall.

  It is therefore understandable the advantage of such a shelter by the simplicity of construction and implementation. In addition and advantageously, the displacement of the elementary modules is carried out by a mechanical system by crank or by means of an electric motor, implementing a wiring system. This is not described, since it does not

  does not relate to the subject of the present invention.

  The shelter according to the present invention therefore has a very simple opening and closing system, between a retracted configuration and a developed configuration,

  favoring loading and unloading operations.

  In addition, it is provided with various systems giving it anti-

  tearing, particularly sought after when it is intended to equip premises

  located outside, and therefore subject to bad weather.

  Finally, by choosing a fully welded structure, aluminum profiles, possibly protected by a polyurethane paint, and by using rails advantageously galvanized in a bath, this resistance is optimized, including under load

  snow, in addition to the longevity of such a shelter.
