Description

REPRESENTATION ROOM
AND / OR TRAVELING PROJECTION
The invention relates to the technical sector of the design and fitting out of a representation and / or projection room which can, for example, constitute a planetarium, a projection room with total screen or the like.

Generally, the representation rooms are established in the form of a fixed construction, which can be dismantled in certain cases, but entailing significant assembly or disassembly times, very largely limiting the conditions of use and increasing operating costs.

For educational purposes and first pedagogical information, in order to reach all the layers of potential population and in particular the young people, and in any geographical place, it was proposed, in particular by the applicant, a traveling representation room defined in the French patent No. 2,677,066. In this document, the traveling representation room was integrated on a trailer having a platform that can be coupled to any tractor vehicle. The structure of the room was then established with side panels capable of pivoting, from their junction plane with the platform, from a horizontal plane to a vertical plane or vice versa, depending on the positions of use or movement of the performance hall. An inflatable envelope was then added to form the representation vault. The folding sides or side panels were then fitted with certain accessories such as furniture, seats and others, which were thus found in a vertical position when said panels were themselves in the raised position. . These arrangements are in fact not very practical and hardly comply with all the desired security requirements.

This technique thus briefly described is interesting, but nevertheless has certain limits as to its use, its reliability and its handling.

The aim sought after according to the invention was therefore to design a new traveling performance or projection room which offers better reliability of use and implementation from a mobile carrying structure which is quick to handle and little binding, and which offers the best security conditions required.

Another aim sought after according to the invention was to guarantee the shape of the representation or projection vault from fixed and non-inflatable support elements, as in patent No. 2,677,066, which can then be subjected to external stresses environment, and to the wind in particular, which could modify the characteristics of representation during projections.

Another object sought after according to the invention was to allow easy storage of all of the components of the room including its seating arrangements, and this in a horizontal plane regardless of the conditions of use or non-use of the performance or projection room.

Another aim sought after according to the invention was, in order to improve the quality of the representation, to dissociate the planetary type projection means or other equivalent source of projections from the support structure of the room seats, subjected to vibration conditions during the arrival and movement of spectators or participants in the room.

Another aim sought after according to the invention was to provide a traveling performance or projection room which fits perfectly on a load-bearing structure associated with any suitable tractor vehicle while meeting the safety criteria and traffic standards of road safety.

These and other objects will become apparent from the following description.

According to a first characteristic, the traveling representation and / or projection room of the type comprises an enclosure forming a vault mounted on a support structure arranged to receive a means of projection and means of movable comfort, characterized in that it comprises a first fixed module formed and arranged from the support structure by defining a shape of a profiled roof in a curvilinear configuration, the width of the roof corresponding to that of the support structure, and in that on either side of said fixed module, are arranged two identical mobile modules and mounted in opposition, said modules being arranged with a profiled roof shape capable of coupling with the aforementioned roof by defining, after installation, a semi-sphere shape defining the screen of the representation or projection room, and in that the said mobile modules can be moved laterally and in a plane h horizontal by means appropriate to the fixed module, by being incorporated tightly into the volume of the fixed module in the transport position of the performance and / or projection room and not in use, and by adapting to said fixed module to define, in the open position, the representation and / or projection room.

These characteristics and others will become apparent from the following description.

To fix the subject of the invention illustrated in a nonlimiting manner in the figures of the drawings where - Figure 1 is a schematic rear view illustrating the traveling representation and / or projection room, according to the invention, associated to a supporting structure, in a transport situation, - Figure 2 is a schematic plan view illustrating the general concept of the room according to the invention, - Figure 3 is a view similar to Figure 1, illustrating the room of representation and / or projection in the deployed position and of use, - Figure 4 is a side view, according to Figure 3, - Figure 5 is a plan view illustrating the representation and / or projection room in conditions of use, - Figure 6 is a partial schematic view illustrating the means for securing the components constituting the arch of representation and / or projection of the aforementioned room.

To fix the subject of the invention, it is now described in a nonlimiting manner.

The traveling performance and / or projection room, according to the invention, is referenced as a whole by (1). The purpose of this representation and / or projection room is to allow representation by cinematographic projectors, slides, films or particular photographs, and finds a particular application as a planetarium.

It comprises a carrying structure which can be a platform (2) secured to a rolling chassis such as a trailer (3) of great length which can be coupled to any tractor vehicle by means of a coupling system (3-1 ) known per se. This trailer has suitable axles known to those skilled in the art. The supporting structure can be defined by the vehicle itself.

This supporting structure thus has a parallelepipedic volume with a rigid roof shape (4) fixedly shaped in a curvilinear shape intended, by its internal part (4-a), to constitute a part of the hemisphere or screen defining the performance hall and / or projection once mounted. The assembly defines a first fixed module (M1).

By way of protection and longitudinally, the supporting structure such as a trailer receives laterally removable and retractable protection panels (5).

In its central part, the supporting structure arranged with a platform forming a fixed floor (6) has an arrangement to allow the positioning of a projection means (7) which can be for example a planetary or any other means for projecting slides, films or others.

Laterally, the carrying structure such as a trailer thus formed has on each of its transverse sides openings forming doors (8) allowing access to the interior of the performance and / or projection room when the latter is formed.

According to a particular arrangement relating to the invention, provision is made, in said load-bearing framework, for the formation of two identical mobile modules (M2), mounted in opposition, and capable of moving transversely, in a horizontal plane, by sliding by with respect to the fixed central floor (6) of the supporting structure and of its platform in particular, and this using any appropriate means. These two mobile modules are identical to each other and are arranged at their upper part with a curvilinear roof form (9) capable of engaging and cooperating with the complementary curvilinear fixed part (4) defined by the roof. of the supporting structure by defining after assembly a screen in the form of a half-sphere then constituting the representation and / or projection vault of the room.

In particular, each of the mobile modules (M2) is laterally translated using jacks, or equivalent means, allowing them to exit over an appropriate distance, with a view to shaping the vault by approximation. The arch parts thus designed are capable, after bringing together and fixing, of defining a continuous, rigid fixed shape defining the screen. The mobile modules are linked to the fixed module of the roof by stapling, for example, or other connecting systems. For this purpose, the fixed arch portion has a profiled peripheral anchoring cavity (4-b) allowing the positioning of a complementary shape (9-a) forming a pin or otherwise established on the movable arch portions of the mobile modules. This gives a solid connection and fixation between them, without affecting the quality of representation and / or projection.

The arch parts thus described are made of any suitable material allowing satisfactory reproduction of the projections. These arch parts can for example be established in a plastic material of the molded polyester type or other material of the same type, the assembly remaining rigid.

The establishment of the room, and in particular the stapling of the movable lateral elements on the fixed part, makes it possible to define, as shown in the drawings, a set of semi-spherical configuration.

Furthermore, the set of fixed (6) and mobile (10) platforms supporting the above-mentioned arch parts (4-b) is capable of vertical elevation by means of hydraulic jacks (11) or equivalent means arranged at from the support frames (2-12) of the supporting structure of the representation and / or projection room and in particular of the corresponding platforms. The actuation of these jacks essentially aims to raise the performance hall with respect to the projection means (7) of the planetary type or other projector to integrate the latter at an appropriate level with respect to the projection conditions.

According to another characteristic of the invention, seats (13) or benches, of molded plastic material, in particular based on polyester, are shaped in the form of different rows to allow the seat of the spectators.

These different rows of seats (13-a - 13-b) are established in the form of crescents, of more or less significant angular sector, certain seats being integral with the fixed platform, and others more eccentric (13-c) integral mobile side platforms of the supporting structure. The shape of all of these seats and their profile, as well as their positioning, is established so that there is a close nesting of the latter when the room is closed for transport, and to reduce the overall volume.

In addition, the row of seats or benches which is located near the interior periphery of the room is established in three parts, a central (13-c) of large sector and two lateral (13-b) being, them, on the fixed platform.

When the traveling room is closed, the portion of large sector seats or benches is fitted by sliding, above or below, on the end seat portions, thereby reducing the overall size of the assembly .

The means allowing such an installation are advantageously guide ramps or the like.

According to another characteristic of the invention, in order to allow access to
Inside the performance and / or projection room, under conditions of use, it is planned to have, near each door (8) integrated in the fixed part of the room, walkways (14) with stairs ( 14a) or inclined ramps (14b) allowing access or exit to or from the room, by all persons, disabled or not.

Additional lighting and sound systems are provided, and equip, in any appropriate manner, the performance and / or projection room. The projection means (7) which is advantageously located in the central part of the room is a planetary for example but can be replaced by other projection means depending on the conditions of use of the room. For example, the planetary can be of the type described in French patent No. 2,624,290 of the applicant.

According to another characteristic of the invention, the sun gear of the aforementioned type can be made autonomous and independent with respect to the framework (2) supporting the representation room during the operation thereof. The projection means is then associated with means capable of making it mobile in position relative to the support frame of the room, these means being of any suitable type and allowing, by their use, to make the projection source independent by compared to the supporting structure, thus avoiding the transmission of vibrations inherent in the use of the room and the movement of people.

The establishment of the representation room is then carried out as follows.

In the initial phase, the room is folded back into its components and modules, as shown in Figure 1, the mobile modules being located inside the fixed volume of the platform. Thus, the two parts (9a) of curved vault of the lateral mobile modules are substantially in planes adjacent to
Inside the fixed part. The seats are grouped one on top of the other for those arranged around the room.

The opening phase consists, after removing the lateral external protections, to separate the two mobile modules laterally with respect to the fixed part, thereby freeing the curvilinear arch parts until they come into the attachment zone and stapling of their respective end part, and defining the semi-spherical screen. The connection being ensured, the vault of the performance hall is then formed and the assembly is then raised by a certain height relative to the support frame.

The seats or benches are then positioned in the desired locations, being guided by any appropriate means. The side walkways to the room are then positioned.

The advantages emerge clearly from the invention and in particular the new concept of realization of the room is emphasized from rigid modular elements, in particular from the vault, allowing a quality, reliability and continuity, of representation without embarrassment of the external environment. . The assembly of the assembly is easy to perform and avoids any lateral tilting as used previously by the applicant contributing to exert significant stressing forces.
