Description:
FIELD OF INVENTION 
     This invention relates to a mobile, elevatable, expandable and retractable viewing studio and a method for providing a mobile viewing studio, in particular for outdoor events for the television media. 
     BACKGROUND OF THE INVENTION 
     Within the television industry there is a segment devoted to the broadcasting and cablecasting of events on location, and in particular, on outdoor locations. Sporting events, such as golf, tennis or beach volleyball, offer prime examples of such events. A need arises to place the announcers and broadcasters in a studio environment at this location. Yet, these announcers and broadcasters also need to be where the action is, with good visibility. 
     Presently the two most common options used to create a television studio environment on outdoor event locations are (1) constructing an elevated temporary studio using construction scaffolding or (2) modifying a portable modular office trailer that is trucked in. Depending on the event, various elevations for the studio or announcers, position are preferred. When elevation is desired, the scaffolding system is used. The scaffolding is erected to a desired height and then the top level is partially enclosed. When elevation is not a factor, a modular office trailer can be used. 
     A third option exists that is not widely used in the industry. It is comprised of a one of a kind studio trailer. This trailer is constructed of wood and steel upon a trailer base and includes an add-on structure for one side that must be attached on-site. This trailer is owned by one individual and used by one company in the industry. 
     The present invention discloses a portable, expandable and retractable, elevatable viewing studio that will meet the composite needs of the television industry. Through integration and modification of existing diverse technologies, the present invention combines the desirable features of the above three on-location television studio options to achieve efficient versatile adjustable on-location viewing. In particular, the present invention offers a viewing studio that is able to accommodate preferred elevation requirements and studio space needs while remaining self-contained and portable. The mobile studio does not require extensive erection and disassembly on site, as with the fixed scaffolding system. The studio is not only portable over the highway system, and adjustably elevatable to achieve the requisite view, but the studio expands to provide studio space requirements for television announcers and broadcasters on location, above and beyond those of a standard bus or trailer. 
     Presently the airline industry uses a variety of hydraulic lift vehicles. E.g. one such vehicle is used to deliver food service supplies to airplanes. Hi-Way, Inc. of Bartow, Fla., manufactures vehicles of this sort. The vehicle is driven to the airplane and elevated to the loading door for loading and unloading supplies. Another similar vehicle is known, an elevatable bus, used to transport passengers from airport terminals directly on to an airplane. 
     The trucking industry has developed designs for fold-out trailers. Versions of such a design are offered for use as cargo trailers or concession trailers. Southern Truck Body Corporation of Tampa, Fla. advertises such trailer designs. 
     The present invention, to achieve its purposes, integrates technologies from these diverse industries into one design. The invention combines the modified technologies of a hydraulic lift vehicle with that of an expandable truck body. This disclosed combination of technologies creates a portable viewing studio system unique to the industry. The invention will be most useful to the television media, although uses outside of this industry can be foreseen, such as a mobile elevatable viewing room for VIP groups at outdoor events. 
     SUMMARY OF THE INVENTION 
     This invention discloses a method for providing a mobile, elevatable viewing studio for on-location outdoor events. The studio is particularly designed for the height and space requirements of the television media. The method includes trucking a studio in a retracted configuration to an outdoor location, the retracted studio having a width, height and length that can be trucked over the normal highway system. The studio at location is elevated to at least ten feet using automatic lift means attached to the truck chassis and studio base. The studio is further expanded in at least one direction. Preferably, the studio is expanded in two opposing directions. The elevating means preferably includes operating a hydraulic lift. The method may further include elevating and lowering a balcony attached to one side or end of the studio. 
     This invention also teaches a mobile, elevatable, expandable and retractable viewing studio system. The system includes a studio having a retracted and an expanded configuration. In the retracted configuration the studio has a width, height and length that permits it to be trucked over the highway system. The studio is attached to a truck chassis. Automatic lift means are attached to and operate between the studio base and the truck chassis. The automatic lift means are adequate to elevate the studio at least ten feet. The studio includes at least one expandable side. Preferably the studio includes two opposing expandable sides. Preferably, the automatically lift means involves hydraulic operation. The system may include an elevatable balcony attached to one side or end of the studio.

Such scissor mechanisms have years of proven experience. Pivot point 54 of scissor mechanism 56 should be designed for easy lubrication. In the embodiment of FIG. 9 the outside of studio body 58 is anticipated to be constructed of a prepainted white aluminum. It is intended that the embodiment provide maximum viewing window sizes 52 to the left, right and rear of studio S. It is further anticipated that windows W will slide open. In the embodiment of FIG. 9, studio S is anticipated to have a body size in its retracted configuration of approximately 25 feet long and 81/2 wide. It is anticipated that such studio S can expand to a expanded configuration of 20 feet wide. Location 48 illustrates the location in the embodiment of FIG. 9 for push button controls for elevating studio S. Keyed locks are anticipated to be available. Balcony B in the embodiment of FIG. 9 comprises a reinforced camera platform of approximately 6 feet by 8 feet. 
     FIG. 10 illustrates a rear view of the embodiment of FIG. 7 wherein the studio is elevated and expanded. FIG. 10 illustrates heavy duty extended stabilizers 60 which are capable of supporting the weight of the vehicle system. Lighting 74 to meet DOT standards for over the road equipment is illustrated. Supports 64 for the extended body of studio S are illustrated in FIG. 10. Width 76 of expanded studio S is approximately 20 feet. Left and right body extension 70 and 68 expand from a custom built studio S body. 
     FIG. 11 illustrates the floor plan of an expanded studio S. The embodiment illustrated in FIG. 7 includes a studio S that expands to offer a studio of dimensions approximately 20 feet by 25 feet, to offer 500 square feet of floor space. 
     FIGS. 12 and 13 offer a rear and top view, respectively, of an expanded studio illustrating a method of expansion and retraction. In the embodiment of FIGS. 12 and 13 sidewalls DD fold into body EE. Walls AA fold down onto floor BB. Floor BB then folds up vertically. Roof CC folds down vertically against floor BB. 
     In operation, studio S in retracted configuration, illustrated in FIGS. 7 and 8, is trucked to an appropriate on-site location. See FIG. 6. FIG. 8 offers a rear view of studio S in retracted configuration as it might be trucked by truck T. Upon selection of a suitable location for the mobile studio, such as illustrated in FIG. 6, truck T is parked as illustrated in FIG. 7. Utilizing lift means L, studio S in its retracted configuration is elevated, as illustrated in FIG. 9. The preferred means of elevation comprises hydraulic lift means. Subsequent to elevation, studio S is extended to an expanded configuration, such as illustrated in FIGS. 10 and 11 or FIGS. 1 through 5. One means for expanding studio S from a retracted configuration to an extended configuration would involve expanding both sides of the studio. The body of studio S could expand, in one means, by folding outwards, as illustrated in FIGS. 12 and 13. The body could fold outwards approximately 7 feet on both sides by such method. In particular, achieving this expansion could involve hinging upwardly side walls of the retracted body of the studio from an expanded floor position. Expanded ceilings or roofs could hinge outwardly from the nonexpanded body. Expanded floor portions could hinge down from the nonexpanded body and expanded front and back outer wall sections could hinge sideways from the body of the retracted studio. It is anticipated that the outer wall and the separate sidewall units would contain extra large viewing windows. 
     Alternately, studio S could expand by other means known in the art of expandable buildings, including telescoping outwardly a wall, floor and ceiling unit. 
     The foregoing disclosure and description of the invention are illustrative and explanatory thereof. Various changes in the size, shape and materials as well as the details of the illustrated construction may be made without departing from the spirit of the invention.
