Definitions

  • the present invention relates to dome structures and, more particularly, to a retractable dome stadium.
  • US-A-4 682 449 which provides the basis for the prior art portion of claim 1, discloses a structure for a stadium roof which is retractable to expose a large rectangular area.
  • the roof sections are relatively massively built in order to provide the necessary span and to be formed as two only separately retracting leaves.
  • the present invention appreciates that a lighter structure can be achieved, as defined in claim 1, using symmetrically truncated, generally lune-shape panels which can readily be retracted and which have the benefits of a spherical dome type structure, rather than a rectangular roof structure.
  • the panels are of identical size and shape which can be stacked in their stowed retracted position and which are readily movable.
  • arches are provided intermediate the length of the panels for supporting the panels during movement and in their closed position with additional tracks receiving the truncated ends of the panels.
  • the present invention is applicable to virtually any type of structure, including stadiums or the like, but for exemplary purposes is illustrated embodied in the athletic stadium of Figures 1-4.
  • the stadium generally comprises an activity surface in the form of a playing area 10, a plurality of tiers of seating 12, seating boxes 14, parking levels 16, pedestrian ramps 18 and like features common to most stadiums.
  • the present stadium is unique in that it can be fully opened and closed utilizing an improved retractable dome arrangement, generally comprising a plurality of generally equal width lune-shaped dome panels 20 movable between a closed position such as shown in Figures 1 and 4 (left side) in which the panels are disposed in side-by-side relationship to define a generally spherical segment shaped dome, and an open position such as shown in Figures 2 and 4 (right side) in which the panels are stacked one above the other.
  • a lune is the surface of a sphere included between two great circles disposed at a given included angle of inclination.
  • the dome of the present invention approximates a circular segment of a sphere and it is the shape of a truncated lune which is used for each of the movable dome panels.
  • the top of the stadium complex is provided with a deck 22 defining a generally circular opening 24 disposed in close and slightly overlapping relationship with the outer ends of panels 20 in all positions thereof.
  • Panels 20 are supported intermediate their ends by a pair of arcuate support rails 26 each having an upper surface having a plurality of arcuate steps 28, one for each panel 20 (Figure 5-7), and which lie generally on a great circle of the imaginary sphere defined by the dome.
  • the center of curvature of each step 28 is coincident with the center of the imaginary sphere with the radius of each step surface differing from the adjacent step surface by an amount approximately equal to the thickness of a panel 20.
  • Each panel 20 has at least two supporting wheels 30 in alignment with each rail 26, and when the dome is closed each panel 20 is directly supported by rail 26 ( Figure 5) with the adjacent edges of panels 20 slightly overlapping one another to provide a weatherproof joint.
  • the two centermost panels 20 abut one another at an interface 32 ( Figure 1) which can be provided with a suitable weatherproof seal.
  • panels 20 When panels 20 are moved downwardly and outwardly to the open position they roll from rail 26 onto the top surface (properly reinforced) of the next lower panel, and so on ( Figure 6-7) until they reach the nested or stacked condition shown at the right side of Figure 4.
  • Rails 26 are held in position by a suitable pair of arcuate supports 34, which can also be located on great circles of the imaginary sphere.
  • Panels 20 are also supported on arcuate arches 40 disposed at each end thereof.
  • Arches 40 illustrated generally in Figures 3 and 4, are substantially parallel to one another, being disposed in parallel vertical planes equally spaced from the center of the dome. The overall arc of each arch is the arc defined by the intersection of the vertical plane in which the arch lies and the imaginary sphere of the dome itself.
  • Each arch 40 has a flat inclined arcuate surface 42 facing the ends of each panel 20 and being perpendicular to the longitudinal axis thereof. Surfaces 42 each lie on the plane of a great circle of the imaginary sphere of the dome, and each has on the face thereof a plurality of parallel arcuate slots 44 through which extend end supports 46 for each of the panels 20.
  • Each support 46 extends for the full width of each panel 20 and is in turn supported on its lower surface by means of a plurality of rollers 48.
  • Support 46 has upstanding outer flange 47 supported on opposite sides by a plurality of rollers 50 and 52 and at the upper edge of flange 47 is a rack 54 engaged by a pinion 56 driven by a plurality of motors 58.
  • Slots 44 in plan, are arcs of a circle having the same center as the imaginary sphere of the dome, and are of a length to accommodate the maximum length of travel of the panel or panels (i.e., at opposite sides of the stadium) disposed therein.
  • the motors 58 for each track are spaced apart a distance less than the length of rack 54 so that each panel will always be under the control of at least one motor. The same is true for the sets of rollers 48, 50 and 52.
  • each support 46 has rigidly affixed thereto a plurality of rods 60 each slidably received within a cylindrical bore 62 at the free end of each panel 20.
  • Each rod 60 extends generally in the direction of the longitudinal axis of the panel and the inner free end thereof is connected to a suitable shock absorbing and/or fluid-type compensating device 64 which is in turn affixed to panel 20.
  • Device 64 can be of any desired construction and serves the purpose of dampening flopping movement of the panels under high wind conditions. They also can serve to compensate for thermal expansion and contraction of the entire structure.
  • Panels 20 may be of any desired lightweight construction, such as a standard spaceframe construction, with the outer panel skin being either fabric or metal, or a combination of both.
  • the structural design of the panels, rails, arches, tracks, etc. can be in accordance with standard engineering and architectural practices based on the anticipated structural and weather loading.
  • the dome In operation, if the dome is closed it is opened by first actuating the motors in the top tracks which control the centermost panel to cause it to start retracting. As it retracts, it rolls over the top of the next centermost panel until they are fully stacked ( Figure 6). Thereafter, the motors for both these panels are actuated to cause them both to retract together ( Figure 7); and so on until the dome is fully opened, or at least opened to the desired extent. Both halves of the dome can be opened simultaneously if desired. The dome may be closed by simply reversing the opening sequence. Operating can be accomplished using conventional controls, sensors and the like.

Abstract

Structure de dôme rétractable telle qu'un stade en forme de dôme, utilisant une pluralité de panneaux de dôme en forme de fuseau, montés pour effectuer un mouvement entre une position ouverte dans laquelle ils sont empilés l'un sur l'autre dans une relation superposée, et une position fermée dans laquelle ils sont disposés dans une relation côte à côte, ainsi qu'un mécanisme de guidage et de deplacement desdits panneaux entre lesdites positions ouverte et fermée. On a aussi mis au point un mode de fonctionnement.
