Description

MOBILE CINEMATOGRAPHIC ROOM, IMPROVED Field of the Invention The present invention relates to the film industry and, particularly, to a mobile movie theater that can be alternatively transformed from a retracted position to a deployed position, to offer virtually all the services of a modern movie theater. , and vice versa, from a deployed position to a retracted condition, for the transportation of said cinematographic room to another location.

BACKGROUND OF THE INVENTION Since the appearance of the first cinematographic projection, worldwide there has been a continuous growth in the demand both for larger spaces and for a greater number of places where films can be projected. However, experience shows us that the construction of cinemas invariably occurs only in towns where the number of real and potential spectators is such that it justifies the enormous investment of economic resources that this type of building requires. Even when film fans can be found almost anywhere, only those who live in the medium and large cities, or in its surroundings, have quick and easy access to this type of show, leaving out all those inhabitants who are not in said urban centers. One way to get the cinema to the population centers lacking formal cinemas has been to temporarily enable auditoriums, classrooms or other similar premises as a cinema, using only a cinematographic projector and sound equipment, the more often than not, very rudimentary. This alternative, although it brings the cinema closer to the public, the conditions in which it does it are not all the ideal that is required and ends up failing to provide the public with a very poor and limited service in terms of the film function itself as well as the lack of additional services that urban cinemas offer. In order to bring the cinema closer to sites that do not have conventional cinemas, the inventor of the present patent application previously developed a transformable cinema-mobile in which all of the aforementioned drawbacks are solved. Thus, in the Mexican patent application No. 948296 the inventor describes a tractor trailer whose trailer is transformed by a hydro-pneumatic push system with pistons, in a cinematographic projection room to comfortably install 80 people. This room has a candy store, bathrooms for ladies and gentlemen, air conditioning equipment, professional audio and video equipment, and finally all the comforts of a modern cinema. Although said mobile-cinema complies with the functions for which it was designed and satisfactorily provides the service offered, due to its specific construction and operation characteristics, it is limited in operation and performance from the point of view of the systems that concur for its operation . Thus, the system of hydropneumatic push through which the mobile sides of the cinema are opened is a highly complex mechanism, which requires the operation of a pump and the laying of an extensive network of pipes that transport the fluid that drives the hydropneumatic pistons of said system. Due to the large number of components of this system the probabilities of failure are high. Likewise, the use of this hydropneumatic system for moving the mobile sides, together with the fact that the floor of the cinema is at an important height above the chassis, does not allow for a sufficiently stable overall structure and firm and there is undesirable vibration and movement. Another limitation of this movie theater is in the seating area, since it is necessary to disassemble all the seats that are located on the moving parts, to return said moving parts of the projection room to its original position and to move the cinema room to other locations. Once the new location is reached, it is then necessary to reassemble all the seats that had been removed in place, now with the purpose of enabling them to their position of use. Still another drawback of the cinematographic room of the patent application No. 948296, of the same inventor, is presented by the projection screen because its two lateral ends must be folded, in lines coinciding with the points from which the parts Moving laterals of the cinema room are pushed outwards. This fact means that there are permanently two lateral lines on the projection screen, which significantly reduce the appearance of said screen and provide a poor image of what is projected on it. Now, in accordance with the present invention, the inventor has developed a series of improvements, innovations and refinements to his inventive concept, such that it provides a new, transformable and improved mobile movie theater, which far exceeds all problems, limitations and drawbacks. presenting the original movie theater.

Objectives of the Invention The purpose of the present invention is to provide an improved, transformable and transportable film room, which can be temporarily installed in areas where there are no conventional cinemas, or simply where a cinematographic projection space is required. temporary, avoiding the large investments required for permanent installations.

Another object of the invention is to provide an improved cinematographic room, on wheels and with the ability to provide excellent accommodation in terms of comfort and operability to an audience of a size similar to that of a small modern movie theater of the type of which only They are found in urban areas.

Still another object of the invention is to provide an improved cinematographic room, transformable and transportable to culturally and commercially remote areas and that do not have installations for the projection of films or similar functions.

Still another object of the invention is to provide an improved, transformable and transportable cinema room that includes, inter alia, access and emergency doors, restrooms, candy store, ticket office and air conditioning system.

These and other objects, features and advantages of the invention will be more clearly appreciated as a result of the detailed description of the invention, which is presented below.

Detailed Description of the Preferred Modes In accordance with Figure 1, the mobile movie theater, referred to hereinafter as transformable mobile cinema (CMT), comprises the following basic elements: a fixed sub-set of support (3), consisting of a basic frame, similar to that of a trailer box of a tractor trailer and which is formed by a chassis (Figures 6 and 7), a platform (not shown) and a roof structure of the trailer. The fixed support subset (3) is practically the backbone that supports all the elements that make up the CMT. Said sub-assembly (3) houses both mobile sides (4) associated with respective roof (T) and floor portions (the latter not shown), as well as front and rear walls (PF and PT). The fixed sub-assembly of support integrates substantially in a single body the chassis, the bridges and the lateral boards, being these practically on the same horizontal plane. This has two very important main purposes. The first is to reduce to the maximum the space that exists between the floor of the room itself and the chassis, as it happens with cinematographic rooms described within the state of the art. By bringing the floor of said room closer to the chassis, the overall structure of the cinematographic room is considerably simplified, at the same time as the interior space of the room is enlarged, reducing even the external height of the fixed sub-assembly of support (3), in comparison with cinematographic rooms of the state of the art. The second purpose is that by integrating the chassis, bridges and side rails into a single body, the fixed support sub-assembly (3) is given excellent rigidity and structural strength, obtaining a structure with greater load capacity and greater stability , eliminating the susceptibility to vibration and undesirable movements when the room is included to its maximum capacity of spectators.

The mobile sides (4), when moving outwards and transversally to the plane on which the sub-assembly (3) extends, define with the latter an interior space of increased dimensions and that is capable of accommodating a large number of people. The fixed support subset (3) basically supports three essential areas namely an auditorium or screening room; an area of services to the public and an area of operational services. The exterior of the CMT has, to the front, an access door (2) provided with its respective access ramp (20) and guardrail (1), and a billboard (42) arranged above the access door (2). ). On the left mobile side (4), contained within the space that it defines and on the area of services to the public, is located a traveling box or box (22) with exterior window (not shown) and equipped with an external awning (47 ) that provides a space with protection and protection against sun and rain. The cabin (22) comprises lifting means (7) [see Fig. 2] that allow said cabin (22) to lower to an appropriate level so that when the CMT is installed in a place for its operation, people have access comfortably and easily to the ticket office for the purchase of your tickets. When the CMT stops working and is ready to be moved to another location, the lifting means (7) raise the cabin (22) to an appropriate height so that the CMT can move freely. When the movable sides (4) are displaced outwards, the cabin (22) is also displaced enough to be released and remains in the descent position. Then, the lifting means (7) are actuated and it is possible to lower and / or raise said cabin (22). The lifting means (7) can consist of any appropriate system, being able to use mechanisms of pulleys and counterweights, operated with electric power or, even, manually. The right moving side (4), towards the opposite part of the access door (2) includes an emergency exit (39) with its corresponding emergency ramp (31) and its handrail (1).

Both the left and right hand sidelines include points of attachment of each of said sides with sliding arms (23) and force transmitting arms (28) (illustrated in Figure 1 only for the right side). The rear part of the transformable mobile cinema or operational services area comprises air conditioning equipment (19), power generating plant (37), switch panel (36) and starter board (35). The fixed sub-assembly of support (3) is attached in the part corresponding to the chassis to two mobile leveling supports (30). Both access (20) and emergency (31) ramps are raised and deployed when the CMT will provide service (Figure 1), and are retracted when the CMT is to be moved to another location. Its operation is through electric motors that drive corresponding pulleys on which the cables that support said ramps are wound. Notwithstanding the foregoing, it is clear that any other system that is appropriate may be employed. As can be seen more clearly in Figures 2 and 3, the CMT of the present invention comprises in the central part of its interior an auditorium that includes a seating area (10) composed of two lateral formations, separated by a central corridor and which are arranged on an appropriate inclined plane to provide optimum visibility from any site of said seating area with respect to a projection screen (14). Rear speakers (8), intermediate speakers (11), front main speaker (13), front upper loudspeakers 15, front lower loudspeakers 33 and a projector 12 complete the CMT audiovisual equipment. Each of the two lateral formations of seats comprises a number of rows of chairs that are out of phase with respect to the rows of chairs of the other lateral formation. Likewise, at least a part of the seats, close to the central region, are folding, being able to throw back both the arms and the seats of the chairs. These two characteristics, in combination, make it possible for both lateral formations to be housed without any additional operation when the CMT is in the transport position, because in that position the rows of chairs of both formations are partially interspersed with each other, as This can be seen more clearly in Figure 8. Consequently, the seating area of the CMT can pass, alternately and with extreme ease, from a retracted position to a deployed position, without the need to dismantle seats or floor sections as is the case with movie theaters of the state of the art. The projection screen (14) is roll-up and has dimensions such that it extends practically from one mobile side (4) to the other mobile side (4). When the CMT is in transport position, the case (not shown) within which the screen (14) is rolled and the screen itself is held on one of the movable sides (4). When the CMT prepares for its operation, the case of the screen is rotated by means of a pivoting element that is located at the apex forming the moving side (4) and the rear wall. In this way, the case of the screen (14) is deposited on the base (32) and then the canvas of the projection screen (14) is deployed to its position of use. To move from the operating position of the CMT to its transport position, the reverse operation is performed to save the screen (14). Behind the wall supporting the projection screen (14) is the area of operational services, necessary for the optimal functioning of the CMT. This area is composed of interior elements and exterior elements. Inside the interior components there is a water tank (16) that supplies the toilets (21), an audio and video control panel (17), a switch panel (36) from where the electric power supplied to the electrical system is controlled. the different lines that feed the different equipment of the CMT, and starter board (35) through which the electric power generating plant is started up (37). Among the external elements of the operational services area of the CMT are the electric power generating plant (37), an elevator mechanism (18) of the power generating plant (37) and the condensing unit (19). Said plant (37) supplies the energy necessary for the operation of the equipment and is capable of being removed from the fixed support sub-assembly (3) by means of the lifting mechanism (18) in order to prevent the transmission of vibrations and stresses to said sub-set (3). Similar to the lifting means (7) the lifting mechanism can consist of any appropriate system, being able to use pulley and counterweights mechanisms, operated with electric power or manually. The air conditioning equipment comprises a condensing unit (19) associated with evaporating units (9), which inject cooled air into the auditorium and extract hot air to the condenser for recirculation. On the opposite side of the operational services area is the public services area, which includes a central lobby flanked to the left by a candy store (41) and a soda dispenser (44); while on the right side of the central lobby there are two toilets (21) for ladies and gentlemen. Lampas (6) provide artificial lighting to the public service area and the auditorium, and a storage area (45) allows the continuous supply of the candy store (41). As seen in Figures 2 and 5, the fixed support sub-assembly is provided with fixed leveling supports (25) and movable leveling supports (30). The function of these is to support the structure on which the floor of the auditorium sits when it is full of spectators. The fixed supports contribute with the tires (26) to support the fixed sub-assembly (3), while the movable supports support the weight of the areas that define the mobile sides (4) when they open, thus avoiding the torsion of these areas. Figures 6 and 7 illustrate in greater detail the relationship between the chassis of the fixed support subassembly (3), the sliding arms (23), the force transmitting arms (28) and the mobile sides (4). The sliding arms (23) are at least four and are arranged in pairs, one towards each of the longitudinal ends of the floor of the CMT. Said arms (23) consist of beams in the shape of "I" and that run in grooves of corresponding form and made on the beams of the chassis of the sub-assembly of fixed support (3). Also, the displacement of the sliding arms is guided by trolleys (3A) attached to the chassis. The sliding arms (23) are arranged in parallel and run in the opposite direction with respect to each other, as indicated by the arrows in Figure 7. The force transmitting arms (28) are at least two pairs, are movably attached to the fixed sub-assembly of support and arranged in parallel and run in the opposite direction with respect to their corresponding pair, as indicated by the arrows in Figure 6. These arms (28) are driven by a main motor (29) arranged horizontally on the fixed sub-assembly of support (3) and moves a transmission chain (29D) that transmits angular movement to an arrow (29C) arranged parallel to the axis of rotation of the engine (28) and on bearings (29A) . The arrow (29C) transmits the same direction of rotation, with the same angular velocity, to the arrow corresponding to the other arms (28). Both pairs of force transmitting arms (28) are connected to the transmission chains (29D) by sliding guides (29F) which move linearly on a displacement bed (29E). The arms located in the upper segment of the chains (29D), which are attached to a mobile side (4), transmit the force necessary to move the corresponding mobile side towards the outside or inside. The same happens with the opposite mobile side (4), which is displaced by the arms (28) located in the lower segment of the chains (29). The direction of movement of the mobile sides (4) towards the outside or inside of the fixed support sub-assembly (3) is governed by the direction of rotation of the main motor (29). Although the present invention has been described with particular reference to a preferred embodiment, it should be understood however that this is only an illustration of the inventive principle and in no way should be interpreted in a limiting manner, since modifications may be made to the dimensions, shape and disposition of the different elements that together make up the mobile cinema, transformable, of the invention; remaining within the same inventive concept and without such modifications constituting another invention, therefore, the scope of the present invention will only be limited by the appended claims.
