Definitions

  • the invention relates to a movie theatre construction comprising a floor on which seats are installed and a projector oriented towards a screen.
  • Such a movie theatre is well known and widely spread.
  • the seats are arranged in a stepped construction and the projector is placed at the back of the theatre so as to project the movie from the back over the whole area on the screen.
  • a drawback of the known movie theatre is that due to the position of the projector vis à vis the screen the light beam incident on top of the screen and the one on the bottom of the screen are incident under substantially different angles. This necessitates a careful construction of the screen, generally a bending of the screen, in order to limit the deformation of the projected image due to that angle difference.
  • the projection of the image on the screen and the construction of the screen as well as the position of the seats must also be adjusted to each other in order to fulfil the imposed requirements and enable the spectator to see an image with limited deformation.
  • a movie theatre construction according to the present invention is therefore characterised in that said floor is substantially continuously inclined with a slope of 5 to 10 % and wherein said screen is mounted at a distance in height of said floor and inclined towards said projector in such a manner that a main axis of a light beam leaving said projector is incident on a substantially right angle on said screen.
  • the inclination of the screen enables to project the main axis of the light beam of the projected image substantially perpendicular on the screen. Therefore the light beam on the bottom of the screen is incident on substantially the same angle as the one on top of the screen. This limits the deformation of the image as the light beam reaching the bottom and the one reaching the top of the screen have travelled substantially the same distance.
  • a first preferred embodiment of a movie theatre construction according to the present invention is characterised in that said projector is placed on said floor.
  • the placement of the projector on an inclined floor facilitates the construction of the theatre as no stepped construction is required thus increasing the security.
  • the placement of the projector on the floor further facilitates the construction and creates a large degree of freedom in adjusting the correct orientation of screen and projector.
  • a second preferred embodiment of a movie theatre construction according to the present invention is characterised in that said projector is placed in an area surrounded by said seats. This enables to find an optimum between the screen dimension and the position of the projector.
  • a third preferred embodiment of a movie theatre construction according to the present invention is characterised in that said seats have at least an inclinable back provided for inclining said back towards a position substantially parallel with said screen. This enables to increase the comfort of the spectators and improves their view of the image.
  • said seat is inclinable under control of a command signal generated under control of said projector upon starting a projection.
  • the seats are only inclined when the movie runs, which facilitates access to and from the seats.
  • the invention also relates to a method for equipping a movie theatre comprising a building of a floor on which seats are mounted and an installation of a screen and a projector oriented towards said screen.
  • the method according to the invention is characterised in that said floor is built with a slope situated between 5 and 10 % and wherein said projector is placed on said floor and said screen is placed at a distance in height form said floor and inclined towards said projector, said projector and said screen being oriented with respect to each other in such a manner that a main axis of a light beam leaving said projector is incident on a substantially right angle on said screen.
  • the movie theatre construction 1 according to the present invention and of which an example is illustrated in figure 1, comprises a floor 2 on which a number of seats 3 are installed.
  • the number of seats is of course determined by the dimensions of the theatre.
  • the seats are preferably so arranged that the distance between the spectators is 140 cm lengthwise and 60 cm breadthwise.
  • the dimensions of the theatre are preferably chosen in such a manner that the minimum and maximum distances of the seats to a screen 6 are approximately equal to 0,7 and 1,8 times the screen width.
  • the projector 4 is installed in a central area of the theatre and is surrounded by the seats 3.
  • the light beam 5 emitted by the projector is incident on the screen 6.
  • the projector is preferably mounted on the floor 2 or in a cavity 7 of the floor as illustrated in figure 2. In the latter case a staircase 8 is provided to access the projector 4.
  • the projector could also be mounted on a support arm fixed on the roof of the theatre.
  • FIG. 3 The determination of the position of the projector in the theatre is illustrated in figure 3.
  • the theatre 1 has been presented as being rectangular. However other geometric configurations, such as for example the one shown in figure 1, are also possible.
  • a reference system x, y having its origin 0 in the middle of the rectangle has been assigned to the theatre 1.
  • the rectangle 1 has a length equal 2(a+b) and a width 2(c+d).
  • the projector 4 is installed in the area 10 i.e. among the spectators.
  • the screen 6 is inclined with respect to the surface of the floor 2 and raised from the floor.
  • the tilt angle ⁇ over which the screen 6 is inclined is situated between 25° and 40° depending on the dimensions and the configuration of the theatre.
  • the projector 4 is also inclined in such a manner that a main axis 9 of the light beam 5 leaving the projector 4 is incident on a substantially right angle on the screen 6, in particular on the centre of the screen.
  • the projector is first installed and then the screen is tilted in such a manner that the main axis 9 is incident on a substantially right angle.
  • the distance between the projector and the screen is at least 3 times the height of the screen and the bottom of the screen is mounted at a height of at least 1,5 m, preferably 2 m of the floor.
  • the screen has a curving of 5,8 times its width.
  • the floor of the movie theatre according to the present invention is not the usual stepped construction but a substantially continuously inclined floor with a slope of 5 to 10 % in an upward direction from the screen towards the end of the theatre. Since the screen is raised with respect to the floor it is no longer needed to use the stepped construction as the spectator looks up to and no longer down on the screen.
  • the inclined floor offers a considerable security advantage in case of emergency since the spectators no longer have to go down the staircase when the theatre has to be evacuated. Moreover such an inclined construction is less expensive to build and offers a better accessibility.
  • the seats 3 will also be inclinable in order to enable the spectator to sit in a recumbent position as illustrated in figure 4.
  • the seat is therefore equipped with adjusting means enabling to incline at least the back thereof towards a position substantially parallel with the screen.
  • the angle ⁇ over which the back will be inclined will therefore vary according to a range ⁇ - 10° ⁇ ⁇ ⁇ + 10° where ⁇ is the tilt angle of the screen.
  • the exact value of the angle ⁇ will be determined by the slope of the floor and the position of the seat on the floor. This inclination is obtainable by either only inclining the back of the seat or by a combined inclination of both parts of the seat.
  • the seat is inclinable under control of a command signal generated under control of the projector upon starting the projection of the movie. Therefore the seats are equipped with an electrical motor which receives the command signal and inclines the seat from an upright position to the programmed inclined position. As soon as the movie is over, the projector generates another command signal to bring the seat back in his upright position. The upright position facilitates the access to the seat and therefore the comfort of the spectator is increased when he or she can leave the seat or sit down on it when the seat is in upright position. As soon as the movie starts, the seat is inclined, bringing the spectator in a comfortable position to see the movie.
  • the inclined position has the advantage that the body weight is carried with a more uniformly spread charge by the seat which is much more comfortable for the spectator.
  • the spectator's body weight is equally distributed over the entire area of the seat what reduces local stresses and contractions which are generally associated with long periods of being seated in a same traditional sitting position. Moreover in this relaxed position the spectator's awareness and receptivity are increased what enables him to enjoy the movie even more.
  • the inclined position of the seat in combination with the inclination of the screen offers the possibility to further reduce the maximum angle between the sightline to the top of the screen and the spectator's straight viewing direction.
  • the minimum free height between the upper side of the spectator's head on a preceding row and the lowest viewline towards the screen is approximately 14 cm due to the seat inclination.
  • the theatre is suitable to be installed in a housing mounted on support pillars which enable to mount the theatre even on an inclined soil and to make the theatre suitable for transportation.
