Abstract
A telescopic seating riser assembly capable of being configured into a variety of seating riser systems. The assembly has a plurality risers having vertically spaced substantially horizontal portions with the risers being movable between an extended position for use and a retracted position for storage. The assembly is further constructed to support deck bridging panels between spaced apart pairs of assemblies, and to utilize a method of supporting at least one deck bridging panel on a pair of spaced apart telescopic seating riser assemblies in an extended position for use and in a retracted position for storage of the assemblies.
Claims25
A telescopic seating riser assembly comprising a plurality of risers having vertically spaced substantially horizontal portions, said risers movable between at least an extended position for use and a retracted position for storage, said assembly further comprising:
- each riser having at least a first rear leg proximate a first rear corner of the riser and at least a second rear leg proximate a second rear corner of the riser wherein in the retracted position the first rear leg of each riser is in substantial forward alignment with the first rear leg of the other risers and the second rear leg of each riser is in substantial forward alignment with the second rear leg of the other risers;
- each riser above a lowest riser further having at least a first front wheel proximate a first front corner of the riser and at least a second front wheel proximate a second front corner of the riser, said front wheels contacting an upper surface of a next lower riser;
- and
- each riser having deck bridging panel supports, said deck bridging panel supports adapted to engage a deck bridging panel when a pair of riser assemblies are spaced apart substantially the length of the deck bridging panel.
A telescopic seating riser assembly comprising a plurality of risers having vertically spaced substantially horizontal portions, said risers being movable between at least an extended position for use and a retracted position for storage, wherein each riser further comprises:
- at least one upward facing deck surface on said horizontal portion;
- at least one pair of rear legs wherein in the retracted position said at least one pair of rear legs of each riser are in substantial forward alignment with said at least one pair of rear legs of each other riser;
- at least one pair of ground engaging wheels proximate said rear legs;
- and
- at least one deck bridging panel support extending outward from said horizontal portion of said riser.
A method of providing support for deck bridging panels in a telescopic seating riser assembly, comprising the steps of:
- providing a pair of spaced apart telescopic seating riser assemblies, each assembly comprising a plurality of risers having vertically spaced substantially horizontal portions, said risers movable between at least an extended position for use and a retracted position for storage, wherein each riser further comprises at least one upward facing deck surface on the horizontal portion and at least one deck bridging panel support extending outward from the horizontal portion;
- and
- supporting at least one deck bridging panel by said deck bridging panel supports on said pair of spaced apart telescopic seating riser assemblies in an extended position for use and in a retracted position for storage of said assemblies.
A telescopic seating riser assembly comprising a plurality of risers having vertically spaced substantially horizontal portions, said risers being movable between at least an extended position for use and a retracted position for storage, wherein each riser further comprises:
- at least one upward facing deck surface on said horizontal portion;
- at least one pair of rear legs wherein in the retracted position said at least one pair of rear legs of each riser are in substantial forward alignment with said at least one pair of rear legs of each other riser;
- each riser having front and rear corners;
- wherein for each riser each front corner is spaced apart from each rear corner a different distance than for each other riser;
- and
- wherein each riser further comprises at least one deck bridging panel support extending outward from said horizontal portion of said riser.
