The mobile theatre comprises of a television screen, with speakers, mounted on top of a motor vehicle via means of a carriage and a studio inside the motor vehicle. The studio comprises of a video player, amplifier, music player and a power generator or invertor. The studio transmits video and audio signals to the television screen and speakers respectively.
Prior art
Vehicles, especially public service buses are known to be fitted with video viewing systems for the passengers inside such buses. Such systems employ use of a television screen, a video player and a tape all located in an appropriate place inside the bus. Such a system is limited to only the fare paying passengers and is thus not enjoyed by a large number of audience. Further the images in most cases are distorted due to the movement of the vehicle.
Summary of the invention.
The above and other limitations of the prior art are overcome in accordance with the present invention which relates to a mobile theatre comprising of a television screen, with speakers, mounted on top of a motor vehicle ,via means of a carriage, and a studio inside the motor vehicle.
It is an object of the present invention to provide a mobile theatre for use in outdoor television shows, advertisements, seminars, conferences, public meetings etc.
 
Another objective of the present invention is to provide a mobile theatre for use in showing television and video shows in rural areas where there may not be electrical power and/or televisions sets are not affordable.

It is yet another objective of the present invention to provide a mobile theatre for use in dissemination of information and advertisement to a large number of people when they are outside a motor vehicle.
Another objective is to provide a mobile theatre with carriage so that the television screen is not exposed to bad weather.

Detailed description of the embodiments
Fig 1 is a side view of the mobile theatre showing one embodiment of the invention. The arrangement includes a carriage(1) permanently mounted on top of a vehicle(3) and showing the television screen(2) inside the carriage(1). The carriage (1) is box like with closeable doors. The carriage (1) has a provision for two speakers (9) on both sides of the television screen (2).
Fig 2 shows a carriage(1) mounted on top of the vehicle(3) and also the studio showing the arrangement of the video player(4), amplifier(5), music player(6) 10 DC/AC invertor(7) and a DC battery(8)
Fig 3 shows the position of the components inside the carriage (1) whereby the television screen(2) stands on a lower spring bed(12) such that the bed absorbs shock when the vehicle(3) is in motion. On top, the screen is secured into
is position by an upper spring bed (10). The lower spring bed (12) is made of a flat plate supported by springs on its underside while in the upper spring bed (10) the springs are on top of the flat plate horizontally the television screen(2) is secured in to position by means of two adjustable latches(11) on both sides . The television screen (2) is sandwiched by two speakers (9) on both the left and right side.
Fig 4 and 5 shows a second embodiment of mounting the carriage (1) on top of the vehicle (3). Instead of the carriage(1) being permanently fixed on top of the vehicle(3), a hinged opening(13) is provided such that the carriage(1) swings inside the vehicle(3) and the opening(13) is covered by one side of the carriage(1).
 
Fig 6 and 7 shows a third embodiment of mounting the carriage (1) on top of the vehicle (3). In this embodiment the carriage (1) is removable from the top of the vehicle (3) and can be placed inside the vehicle (3) when the theatre is not in
use. Two hollow bars (14) are permanently welded on top of the vehicle (3). The carriage (1) is then provided with two extrusions (17) at both ends to slidably engage into the two hollow bars (14). The hollow bars (14) are also provided with means for locking the carriage extrusions (17) into place. Such locking means include bolts and nuts (16) accommodated by a set of holes (15) drilled along the length of the hollows bars (14).

In operation, when the vehicle (3) is in motion, the carriage (1) is either on top of the vehicle (3) for the first embodiment or inside the vehicle (3) for the second and third embodiments of mounting the carriage. When the vehicle (3) gets to the sight where the show is intended to be screened the carriage (1) is ejected to
is the top of the vehicle (3) for the second embodiment of mounting the carriage or
slidably engaged to the two hollow bars (14) welded on top of the vehicle (3)
according to the third embodiment of mounting the carriage. The carriage (1) is
then locked in to place by means of bolts and nuts (16). The studio is then
turned on. The Studio draws power from the vehicle's DC battery(8) through the invertor(7) which converts the DC battery output to 240 volts AC. Alternatively a generator providing 240 volts AC may be provided instead of using the vehicle's battery(8) and invertor(7). This will prevent drainage of the vehicle's battery (8) in case of long shows. The television screen (2) also gets its power from the same source as the studio. The amplifier (5) is used to amplify the audio sound so that a wide audience as possible is reached.
The music player (6) provides music whenever required.
