Abstract
Abstract A transportable stand construction system generally comprised of a plurality of seat modules. The system includes a support frame, support means on the support frame to be spaced from and normally parallel to a surface on which the system rests, and a floor-carrying member which is part of the seat module. Connecting means are arranged adjacent a rear end of the floor-carrying member and are locatable on the support means to position the rear end of the seat module substantially horizontally. The front end of the floor-carrying member is arranged to be supported directly by the surface beneath the system or by support means of a further support frame to be arranged at a lower level than the support means of the first support frame. The system also normally includes modular step members to provide gangways spaced at predetermined distances by a series of the seat modules.

Dependent Claim
52 words
The modular stand construction system recited in claim 1 wherein said modular step member comprises a floor-carrying member and floor means mounted on said floor-carrying member forming said steps, alternate ones of the steps on said modular step member having a greater surface area than the surface area of the intermediate steps.
Claim 4
Dependent Claim
37 words
The modular stand construction system recited in claim 2 wherein each said step of larger area extends partially over the rearward surface of each said intermediate smaller area step thereby facilitating the provision of larger area steps.
Claim 5
Dependent Claim
188 words
A modular stand construction system comprising: a support frame; support means on said support frame to be spaced from a surface on which the system rests; at least one modular seat member comprising: a floor-carrying member; floor means mounted on said floor-carrying member; and at least one collapsible seat coupled to said floor means, said collapsible seat being engaged with said floor means when in an erect position and being movable from the erect position to a stowed position beneath said floor means whereby said floor-carrying member and said floor means provide an envelope within the external dimensions of which said seat is fully enclosed when in the stowed position, thereby facilitating transportation and storage of said modular seat members while protecting said seat; and connecting means adjacent a rear end of said floor-carrying member locatable on said support means to position said rear end essentially horizontal, said floor-carrying member having its front end arranged to be supported directly by the surface or by support means of a further support frame to be arranged at a lower level than the support means of the first said support frame.
Claim 6
Dependent Claim
188 words
A modular stand construction system comprising: a support frame; support means on said support frame to be spaced from a surface on which the system rests; at least one modular seat member comprising: a floor-carrying member; floor means mounted on said floor-carrying member; and at least one collapsible seat coupled to said floor means, said collapsible seat being engaged with said floor means when in an erect position and being movable from the erect position to a stowed position beneath said floor means whereby said floor-carrying member and said floor means provide an envelope within the external dimensions of which said seat is fully enclosed when in the stowed position, thereby facilitating transportation and storage of said modular seat members while protecting said seat; and connecting means adjacent a rear end of said floor-carrying member locatable on said support means to position said rear end essentially horizontal, said floor-carrying member having its front end arranged to be supported directly by the surface or by support means of a further support frame to be arranged at a lower level than the support means of the first said support frame.
Claim 7
