Definitions

  • ABSTRACT A large auditorium is partly formed by a floor plate obliquely inclined relative to the horizontal and centrally mounted for rotation about a vertical axis on a base by means of a hub from which lattice girders radiate toward the periphery of the floor plate.
  • Rows of seats on the floor plate face toward the lowermost part of the periphery while a wall approximately semicylindrical about the axis of rotation rises from the uppermost part of the floor plate periphery.
  • the floor plate may be turned 180 into a position in which it is separated from the stationary remainder of the large auditorium by the semicylindrical wall and constitutes a smaller auditorium of its own.
  • the invention provides a turntable including a hub portion rotatable on a base about a vertical axis, a floor plate having a central portion near the axis of rotation and a peripheral portion radially remote from the hub portion, and a plurality of carriers fastened to the hub portion and elongated radially outward from the hub portion in angularly offset relationship.
  • the carriers extend to the peripheral portion of the floor plate and support the latter.
  • An upright wall mounted on the turntable extends upward from the peripheral portion of the floor plate approximately about the axis of rotation and defines an opening directed radially away from the axis. Rows of seats on the floor plate face away from the wall.
  • FIG. 1 shows an auditorium of the invention in fragmentary elevational section
  • FIG. 2 is a fragmentary top plan view of supporting elements of the auditorium of FIG. 1;
  • FIG. 3 shows a modified detail of a lattice girder in the apparatus of FIG. 1 on a larger scale
  • FIG. 4 shows yet another modification of the same girder
  • FIG. 5 shows the turntable bearing and associated elements of the apparatus of FIG. 1 in elevational axial section on a larger scale
  • FIG. 6 shows a modified base and hub for a turntable in the auditorium of FIG. 1 in a corresponding view on a larger scale.
  • FIG. 1 there is seen a turntable 11 set into a conforming pit in the fixed floor 12 of an auditorium which slopes obliquely downward toward a nonillustrated stage.
  • a base 24 is arranged in the center of the circular pit 10, and an annular ball bearing track 23 on the base carries the hub portion 20 of the turntable 11, a polygo-.
  • the top beams extend in a plane parallel to the oblique top surface of the hub portion 20 and support a floor plate 18 of reinforced concrete.
  • the floor plate 18 is of uniform thickness over most of its length and width and is elliptical in shape, the ratio of the major and minor axes of the ellipse being such that their orthogonal projections into a horizontal plane are of equal length.
  • a depending, peripheral rim 18' of the floor plate 18 thus appears as a circle in the view of FIG. 2, and the girders 19 appear to be of equal length in the same view. They are attached to the hub portion 20 equiangularly relative to the axis of rotation and taper transverse to their direction of elongation in respective vertical planes as the top and bottom beams of each girder approach each other in a direction toward the peripheral portion of the floor plate 18.
  • the bottom of the wall 14 is movably received in a horizontal groove 15 of the fixed floor 12 which circles the pit 10. The same groove also receives the lowermost part of the rim 18'.
  • the wall 14 is held in its upright position by braces 16 connecting its bottom to several girders 19, only one brace being shown in FIG. 1.
  • the weight of the wall 14 is balanced by a counterweight 17 attached to the lowermost peripheral part of the floor plate 18, more specifically, to a girder supporting the lowermost part of the floor plate 18.
  • the wall 14 laterally bounds an opening directed toward the lowermost part of the floor plate 18 and the non-illustrated stage. Rows of seats 13, only partly indicated in FIG. 1 in order not to crowd the drawing, are arranged on the floor plate 18 and face the lowermost peripheral portion of the turntable and away from the wall 14.
  • the ball bearing track 23 has a two-part inner ring 26 provided with partly threaded vertical bores 25 normally receiving non-illustrated heavy screws that fasten the two parts of the ring 26 to each other and to the base 24.
  • the two parts of the ring 26 provide annular races 28 for two vertically offset groups of bearing balls 27.
  • An outer ring 30 provides corresponding annular races 29 for the two sets of bearing balls and is axially secured by the balls on the base 24, not itself seen in FIG. 5.
  • Bolts normally received in threaded bores 31 of the outer ring 30 fasten the hub portion 20 to the outer ring.
  • the outer circumference of the ring 30 carries an integral gear rim 32.
  • FIG. 1 there is seen an electric motor 33 mounted on the base 24 and having a pinion 34 coaxially mounted on its output shaft.
  • the pinion 34 mesheswith the gear rim 32 fixedly fastened to the hub portion 20, and the motor 33, when energized, turns the entire turntable assembly into a non-illustrated position'in which the wall 14 separates the floor plate 18 and the seats 13 thereof from the seats on the stationary auditoriumfloor l2 and the non-illustrated stage mentioned above.
  • the seats 13 on the floor plate 18 face toward the right, as viewed in FIG. 1, and toward another stage or the like that may be provided there, the size of the smaller auditorium so created being equal to the top face of the plate 18.
  • the several girders 19 must differ in length in order to reach to the rim 18'. It has been found advantageous to assemble all girders from a major longitudinal portion identical in each girder, and constituting the entire shortest girder, and longitudinal extension pieces attached to the several identical major portions.
  • the two illustrated lattice girders l9 consist each of a major longitudinal portion 35 of uniform size and shape, and of an extension piece 36 welded to the girder portion 35 and connecting the same to an upper lug 21 on the hub portion 20.
  • the basic girder portion 35 is supplemented by an extension piece 37 at its narrow, radially outer end which provides greater length to the top and bottom beams of the girder 19' and includes cross members connecting the added longitudinal members.
  • an extension piece 38 increases only the length of the top beam.
  • Girders 119 more similar to each other in shape and size may be employed in the turntable arrangement partly illustrated in FIG. 6.
  • the hub portion 120 of the turntable consists of two cylindrical portions of equal diameter welded to each other in such a manner that their axes intersect at the angle at which the floor plate 118 is inclined relative to the horizontal.
  • the girders 119 which carry the plate 118 radiate from the upper part of the hub portion 120 while the lower part is attached to an annular ball bearing track 123 not significantly different from that shown in FIG. 5 and equipped with an external gear rim 132 as described with reference to FIGS. 1 and 5.
  • the diameter of the track 23 is but a small fraction of the length or width of the floor plate 18 so that the support 24, the hub portion 20, and the counterweight l7 occupy relatively little of the pit 10.
  • the pit is accessible through a door in the portion of the structure cut away in the view of FIG. 1 and may serve as a storage space or for other purposes.
  • the invention has found a particularly advantageous application in an auditorium having an inclined floor, as illustrated, it is also used to advantage in an auditorium having a horizontal floor.
  • the floor plate on the turntable may be circular, but may be of different shape. It will also be obvious, that the floor plate 8 need not be elliptical to achieve the advantages of this invention.
  • An auditorium comprising:
  • a turntable including 1. a hub portion,
  • said arrangement including two annular groups of bearing balls, and inner and outer ring means secured on said base and said hub portion respectively.
  • said ring means defining a pair of inner bearing races and a pair of outer bearing races centered in said axis
  • said floor plate being obliquely inclined relative to said axis, whereby respective parts of said peripheral portion offset from said axis in opposite directions are uppermost and lowermost,
