Abstract

A cinema structure (1 ) comprises an auditorium (12) defined between a floor (2), a ceiling (3), front and rear walls (5,8) and side walls (10), which is of length (L) similar to its width (W) and of height (H,) approximately half its width (W). A screen (14) which is substantially the width and height of the auditorium (14) is located adjacent the front wall (5). Rows (17) of seats (18) are tiered upwardly rearwardly at an angle of approximately 22.5°. The front row (17a) of seats (18) is located on the floor (2), while the second and subsequent rows (17) of seats (18) are mounted on corresponding plinths (20). The rearmost plinth (20a) is located adjacent the rear wall (8) and is spaced apart downwardly from the ceiling (3) a height (H2) of approximately 2 metres. A projector (24) in a projector housing (23) is located centrally on the rearmost plinth (20) within the auditorium (12), and a lens port (22) of the projector (24) is located at a level of approximately 0.5 metre below the ceiling 3.

Abstract

A cinema structure (1) comprises an auditorium (3) having a flat planar screen (10) onto which images of a motion picture is projected by a projector (12) located adjacent a rear wall (5) of the auditorium (3). Seating (14) comprising rows (15) of seats (16) are supported on tiered plinths (18) which are tiered at an angle a of approximately 25°. A front row (15a) of the seats (16) is formed in two parts, namely, a left-hand part (44a) and a right-hand part (44b) on a front plinth (18a), which is also formed in two parts, namely, a left-hand part (42a) and a right-hand part (42b). The left and right-hand parts of the front row (15a) and the front plinth (18) define central gaps (45,43, respectively) in order to accommodate the projected beam of the motion picture uninterrupted from the projector (12) to the screen (10). The rows (15) of seats (16) are pitched at a horizontal pitch (P1) of 1,300mm, and each plinth (18) is at a vertical height (h^ of approximately 600mm above its adjacent plinth (18). The front plinth (18a) is at a height of approximately 1,200mm above a floor (8) of the auditorium (3). The screen (10) extends substantially the width of a front end wall (4) between opposite side walls (6) of the auditorium (3), and extends substantially the full height of the front end wall (4) between the floor (8) and the ceiling (9) of the auditorium (3).
