(31. 52-10 ABSTRACT OF THE DISCLOSURE A theater construction in which a plurafity of stages are arranged around a seating area. The seats are arranged so that they can be moved to face in different directions and the vertical elevation of the seats can be changed so that patrons can view any of the stages.

This invention relates to a theater construction and more particularly relates to a theater construction employing rotatable, vertically adjustable seating equipment for seating an audience in a theater or hall.

In the construction of theaters it has long been the practice to provide stationary seats facing a single stage area. Traditionally, rows of seats have been placed such that those nearest the stage are at the lowest elevation and the rows are placed at progressively higher elevations toward the rear of the theater, thus making it possible for those seated toward the rear to see over those seated in front. Although this arrangement has been in use for a very long time, it has numerous disadvantages, foremost of which is that generally only a single stage area is provided. This usually requires a substantial break during a production while the scenery is hastily changed. This also often places practical limits on the number of scenery changes that can be made during a production. The traditional seating arrangement has an additional disadvantage in that seats in the rear of the auditorium are far from the stage and, thus, usually must be sol-d at a lower price than those closer to the stage.

Some attempts have been made to overcome these disadvantages. For example, one or more rotatable platforms have been used to move persons past stationary centrally located viewing areas. This, however, has the disadvantage in that the attention of the entire viewing audience cannot be focused on one area at one time.

Thus, the objects of the invention include:

(1) To provide a theater construction in which the viewing direction of the entire audience can be progressively changed between a series of stages or viewing areas.

(2) To provide a theater construction, as aforesaid, in which the viewing direction can be quickly and easily changed during a production.

(3) To provide a theater construction, as aforesaid, which can be quickly and easily changed from a traditional front stage arrangement to an arena stage arrangement.

(4) To provide a theater construction, as aforesaid, in which a wide variety of different stage arrangements can be provided.

(5) To provide a theater construction, as aforesaid, in which the stage scenery need not be hurriedly changed between scenes but might possibly remain in place for the entire run of a production.

(6) To provide a theater construction, as aforesaid, in which the various seats are of more equal desirability.

(7) To provide a theater construction, as aforesaid, which can be provided with tables so that meals and/or refreshments can be served to the partons.

Other objects and purposes of the invention will be- 3,394,5fi5 Patented July 30, 1968 come apparent to persons acquainted with theater design upon reading the following specification and upon inspection of the accompanying drawings.

General description In general, the invention provides a theater construction comprising a seating area defined by a plurality of platforms each of which is supported for independent vertical movement, preferably by hydraulic equipment. A turntable is rotatably mounted on each platform and said turntable is adapted to be rotated by suitable mechanism, such as an electric motor located on the platform. A plurality of seats are mounted on each of said turntables. The seating area of the theater is at least partially surrounded by a plurality of stage areas. Control means are provided to rotate the turntables so that the seats can face each of the stage areas in succession. The control means also effects vertical movement of the platforms so that the platforms closest to the stage area being viewed are lowermost and the remaining platforms are at progressively higher elevations in a direction away from said stage area.

Detailed description The theater 10 (FIGURE 1), which illustrates a preferred embodiment of the invention, is comprised of an entrance 11, a central seating area 12 and a plurality of primary stages, such as right stage 13, left stage 14 and center stage 16, the stage areas being located outside of and at least partially surrounding the seating area. The primary stages may be either of a movable or a stationary design. Smaller stages 17 may be positioned between said primary stages. The theater has storage zones for storing movable stages or scenery when same are not in use. The remaining areas of the theater such as the ticket booths, business oflices and make-up rooms may be of a conventional nature.

The seating area 12 (FIGURES 1, 2, and 3) is comprised of a multiplicity of individual turntables 18. The arrows on said turntables indicate the viewing direction, that is, the direction in which the seats on the turntables face, which direction may be changed, as hereinafter described. The turntables are arranged in rows and the rows, as shown in FIGURE 4, are usually arranged at progressively higher elevations in a direction opposite the viewing direction so that portions farther away from the stage being viewed are better able to view the stage. The reference characters F and 1-10 on the individual turntables indicate the vertical positions of the turntables, the reference character F being applied to turntables at the floor level and the reference characters 1-10 indicating progressively higher elevations above the floor. The number of rows and the number of turntables within a given row may be selected to conform with the size and shape of the given auditorium.

The portion facilities on each turntable 18 may be designed in accordance with the desires of the theater operator. However, a preferred design is illustrated in FIG- URE S. In the preferred arrangement the walking surface is carpeted and two tables 19 and 22 are provided for use, such as serving either foods or beverages. Placed behind the front table 19 are a plurality of seats 21, four seats being illustrated. The rear table 22 is here shown as having five seats positioned behind it. It seats of a swivel type are provided, two additional seats may be included, as indicated in broken lines. An aisle 20 is provided between the forward seats and the rear table. It will be understood that the tables 19 and 22 can be omitted if it is desired to provide only seating facilities.

The turntable 18 (FIGURE 5) is preferably recessed in a central opening in the upper surface 23 of a square base or platform 24 so that the upper surface of said turntable is substantially flush with said upper surface of the platform. The platforms 24 should fit in close proximity to each other to avoid stumbling by patrons and to prevent articles from slipping between said platforms. Each of the platforms 24 may have depending side walls 26 (FIGURE 4) on each of its sides. Additional platforms 25, which do not have seats, are located around the seating area 12 and same can be provided with guard or hand rails (not shown) for the use and protection of patrons as they enter or leave the theater. The platforms are each positionable at the same vertical levels as the platform 24 adjacent thereto and they form a peripheral aisle so that patrons can leave the theater while the platforms are in raised positions. Vertically movable stairways of the type illustrated in greater detail in FIGURES 11 and 12 are provided to permit patrons to walk from the raised turntables to floor level in the entrance 11.

Referring to FIGURE 6, each platform 24 is supported upon the upper end of a piston rod 27 and said platform is slideably engaged with and guided for vertical movement by upright guides 28. The piston 27 is vertically slideable within an upright pressure fluid cylinder 30. The cylinder 30 and the upright guides 28 are securely mounted at their lower ends upon floor 31. The upright guides 28 are constructed of metal, such as steel, and their stability is further increased by the provision of cross struts 29.

Pressure fluid is supplied by a pump 32 which forces a fluid from reservoir 33 into line 34. If the four-way valve 36 is in the up position, the fluid passes into line 37 and from thence into the lower end of cylinder 30 causing piston 27 to rise thereby elevating platform 24. Simultaneously, fluid from the upper end of cylinder 32 is forced back through line 42, through four-way valve 36, thence 4 into line 43 and finally the fluid returns to reservoir 33. If the platform is desired to be lowered, four-way valve 36 is placed in the down position and fluid is pumped from line 34 through valve 36 into line 42, thence into the upper end of cylinder 30 forcing piston 27 downward while the fluid from the lower end of the cylinder 30 passes through line 37, then line 43 and finally into reservoir 33.

The valve 36 is of a conventional type such that the platform can be elevated to, and held at any of eleven vertically spaced positions corresponding to the vertical elevations F and 110 shown in FIGURES l, 2, and 3. To assure proper vertical positioning of the platform, a switch actuator 45 carried by the platform is cooperable with switches 46 which are supported in vertically spaced relation so that the switches are actuated in response to vertical movement of the platform. A master control system coordinates the operation of the individual valves for the platforms so that each platform is automatically placed at the proper elevation for the particular seating arrangement being provided.

The platform 24 has a base plate 40 secured thereto. The turntable 18 has a downwardly extending shaft 48 which is rotatably mounted and supported by bearing 50. Further support for the turntable 18 is provided by the rollers 47. A power source, such as an electric motor 49 is mounted on the base 40 and said motor has a geared power wheel 51 which drivingly engages annular gear 52 on the underside of the turntable so that the turntable can be rotated in order that the seats thereon can face in any desired, predetermined direction.

The master control system (not shown) in addition to automatically controlling elevation of the platforms also enables the operator to simultaneously rotate all turntables to the desired viewing direction. The master control system can be of any suitable type and since the details of such a system will be readily apparent to persons acquired with equipment of this type and form no part of the present invention, a detailed description thereof is believed to be unnecessary.

In order to reduce the number of piston and cylinder units, it may be desirable to provide rotatable turntables 18A having two or more seating levels as illustrated in FIGURE 13.

Further, each of the individual seats could be mounted for pivotal movement on its platform, in which case it would not be necessary to provide rotatable turntables.

Operation Although the operation of the invention has been indicated somewhat above, said operation will be repeated to insure a more complete understanding to the invention.

Assuming the turntables 18 to be all properly positioned, both vertically and horizontally, for viewing the right stage 13 as shown in FIGURE 1, the viewing direction and elevation can be adjusted so that the patrons can view the center stage 16 by the following. The turntables are each rotated by their motors 49 so that their seats face the stage 16. Simultaneously the elevation of the respective platforms is changed so that the row closest to stage 16 is at floor level and other rows of platforms are positioned at successively higher levels in a direction away from the stage 16. Similarly the corner stages 17 can be viewed by adjusting the viewing direction and elevation of the platforms as illustrated in FIGURE 2.

An arena stage arrangement can be created by removing the seats from a group of center platforms and positioning them at the 1 level to form a stage, as shown in FIG- URE 3. An entrance and exit for performers can be provided by removing seats from certain other platforms and positioning them at floor level as shown. All remaining turntables are rotated to face the center and each row from the stage out may be placed at progressively higher elevations. It will be understood that guard rails will be provided on the sides of the platforms adjacent the entrance and exit aisles for safety purposes.

A further modification of the invention in which the theater has a circular exterior shape, is illustrated in FIGURE 9. The seating area 12A is comprised of a plurality of turntables 18B and platforms 24B and 25B identical to the turntables and platforms described above and therefore same need not be further described. A series of stages 55 completely surround the seating area so that a multiplicity of scenery arrangements can be provided. The stages 55 can be mounted for vertical movement so that same can be moved into the basement of the theater for scenery changes. Also bleacher seats can be placed on the stages 55 when the theater is used in an arena seating arrangement or on other occasions when extra seating is desired. A draw curtain 56 may be provided for concealing the stages 55 not in use. A main stage 57 having a proscenium arch also is provided.

A movable orchestra cart 58 may be provided between the seating area and the stages. This will enable the orchestra to be placed adjacent the stage which is presently being used and to be shifted from stage to stage as required.

Stairways 59 are provided so that the actors can go to the basement of the theater when necessary.

The stage level 61 is positioned a suitable distance, such as about 9 feet, above floor level, that is, the lowest level at which the platforms 24A can be placed. Passageways 62 are provided underneath the stage level on four sides of the seating area whereby patrons can enter or leave the seating area.

Stairways 64 (FIGURES 9, 11 and 12) may be pro vided which cooperate with the vertically movable peripheral platforms 25B. Each stairway 64 may be comprised of a plurality of individual stair steps 66, each being vertically movable by pistons 67 in the same manner as the seating platforms 18B. The steps 66 are arranged so that the step adjacent the platform 25B is one step below the level of the platform and the remaining steps are at progressively lower levels. The stairway 64 at the rear (highest level) of the seating area, as shown in FIG- URE 11, is fully extended. The stairway 64 at the front (lowest level) of the seating area during viewing of the stage, as shown in FIGURE 12, provides only four steps. The side stairways provide an intermediate number of steps. Thus, the stairways 64 can be arranged in any desired manner so that patrons can easily enter or leave the seating area even when the platforms are raised. It will be understood however, that the platforms will be positioned at their lowest levels before and after the performance and at intermissions. In this embodiment, seats are omitted on the two mutually perpendicular central rows of platforms to provide aisles for patrons to enter or leave the seating area during a performance.

Similarly a variety of other stage arrangements may be provided, such as the one illustrated in FIGURE It), simply by removing the seats from the appropriate turntables and elevating the platforms to the proper level.
