FR2813202A1 - Barge, used for showing films and staging live performances by the water's edge, comprises a projection room at stern and back-projection screen at forward end - Google Patents

Abstract

The barge has a stern cabin with a projection room (1) containing a 35 mm projector, a generator (12) and living accommodation (5). At the forward end it has a back-projection screen (2) mounted on a movable metal frame, a stage (14) and a curtain (13). The equipment is mounted on two hulls (6) and stabilized by a system of jacks (3) with feet that engage in the bed beneath the water.

Description

<Desc / Clms Page number 1>
The present invention relates to a floating device allowing the implementation of cinematographic projections, as well as the implementation of live shows by the shore (shorelines, lakes, rivers ...).

Cinematographic projections, on the shore, when it comes to placing the screen above the water, usually require a great deal of preparation time as well as the implementation of titanic means. In addition, these have major technical disadvantages - relating to the wind: development.

- relating to water movements: development, framing. The device according to the invention makes it possible to remedy these drawbacks. Indeed, the first characteristic of the present device resides in the fact of securing a rear projection screen, with plexiglass structure, and the projection equipment on a barge.

The device has as a second characteristic, a system of submersible jacks making it possible to stabilize the barge after mooring (by way of nonlimiting example, the present barge having dimensions of 18 × 10 meters, the jacks are six in number).

The accompanying drawings illustrate the invention. Figure 1 shows the device seen from above. Figure 2 shows the device seen from the side. Figure 3 shows the device seen from the front.

With reference to these drawings, the barge device for cinematographic projections and live shows, according to the invention comprises A) A projection booth (1) equipped with traditional 35 mm: a 35 mm projector with reverse sound player, specific to rear projection (8), a rectifier (9), a large reel unwinder (10), an assembly table (11). A large space is left free in the center of the cabin to allow the installation of other types of projection equipment (16 mm, video projector ...).

B) A rear projection screen (2) with plexiglass structure, the rigidity of the plexiglass making it possible to shield the screen from the influence of the wind and therefore from focusing problems. The screen, mounted on a metal frame, is retractable or removable. The screen frame is held on the screen frame (15), and on the front of the stage (14), by removable hinges allowing to position the screen according to the use of the device a) On the stage (14), to facilitate navigation.

b) Above the stage (14), or on the trampoline (16), in order to facilitate the implementation of live shows.

c) On the screen portal (15), for film projections.

C) A system of jacks (3), which, once the device is moored, and in the event of calm sea (or water surface), makes it possible to stabilize the barge by securing it to the seabed (or lake, river bottom ...). The feet (17) provided with a ball joint (18) adapting to all types of funds or underwater soils. In the event of rough seas, the jack system allows the barge to be raised, thus removing the hulls (6) from the influence of the movement of the water.

 D) A stage (14), measuring (by way of nonlimiting example) sixty square meters, makes it possible to host various types of live shows: theatrical performances, concerts ...

E) A nylon stage curtain, placed in front of the screen (2) and suspended from the curtain frame (13), touches the surface of the water. The curtain is the only part of the device visible from the shore before the cinema or live performance begins.

F) A generator allows the device to be completely autonomous.

G) A habitable cabin (5), adjoining the projection cabin, can accommodate the skipper and the projectionist.
