Movable device for use in ceiling to fix digital projector in cinema room, has braces for supporting surrounding structure with hollow steel profile, and upper support frame connected with lower framework holder

Abstract

The device has a surrounding structure connected to a belt cover (2) by a plate (1), and braces for supporting a surrounding structure with a hollow steel profile (3). An upper support frame (6) is connected with a lower framework holder (7). Structural tubes of a platform inferior (11) support a base of the device, where the device pays attention to vertical braces by the plate. A thread (8) is provided with a case (9). A hatch (16) manipulates a projector (12). The surrounding structure is provided with insulating material, where dimension of the hatch is about 80x80 cm. USE - Movable device for use in a ceiling to fix a digital projector in a cinema room. ADVANTAGE - The device pays attention to the vertical braces by the plate, and the thread is provided with the case, thus avoiding sound transmission between a projector and a cinema room, forming isolation between two semi light partitions with a cardboard board, placing a suspended digital projector of a ceiling without work force and reducing space and manufacturing cost of the device.
