Abstract
Abstract A displaceable knocked-down building unit defining a playing enclosure for use as a court for off-the-wall games. The unit has rigid external skeleton structures on the inside of which are secured wall panels thereby defining the playing enclosure. The means securing the wall panels of at least one wall which is to serve as the ball-bouncing wall are secured wholly on the outside of the panels whereby the said panels form an inner face for ball-bouncing purposes which is flat, continuous and devoid of projecting parts.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
199 words
A displaceable building unit defining a playing enclosure for use as a court for off-the-wall games requiring at least one wall suitable for the bouncing-off of a ball, comprising: a frame made up of at least one end skeleton structure and two side skeleton structures fixed to said end skeleton structure; flat wall panels and resilient means securing said wall panels to said structures on the inside thereof with respect to said playing enclosure; said resilient means detachably connecting said panels to said structures at spaced apart locations; wherein each panel is a cellular construction comprising an inner skin, an outer skin spaced from and parallel to said inner skin, and a plurality of spaced apart webs extending transversely of the panel between said skins, said panels being disposed on said structures so that the outer surface formed by said panel inner skins is unbroken, and wherein said resilient means detachably securing said panels of said ball-bouncing wall project solely toward the outside of said panels with respect to said playing enclosure whereby the inner face of said ball-bouncing wall is flat, continuous and devoid of projecting parts so as to be suitable for use in an off-the-wall game.
Claim 2
Dependent Claim
199 words
A displaceable building unit defining a playing enclosure for use as a court for off-the-wall games requiring at least one wall suitable for the bouncing-off of a ball, comprising: a frame made up of at least one end skeleton structure and two side skeleton structures fixed to said end skeleton structure; flat wall panels and resilient means securing said wall panels to said structures on the inside thereof with respect to said playing enclosure; said resilient means detachably connecting said panels to said structures at spaced apart locations; wherein each panel is a cellular construction comprising an inner skin, an outer skin spaced from and parallel to said inner skin, and a plurality of spaced apart webs extending transversely of the panel between said skins, said panels being disposed on said structures so that the outer surface formed by said panel inner skins is unbroken, and wherein said resilient means detachably securing said panels of said ball-bouncing wall project solely toward the outside of said panels with respect to said playing enclosure whereby the inner face of said ball-bouncing wall is flat, continuous and devoid of projecting parts so as to be suitable for use in an off-the-wall game.
Claim 3
Dependent Claim
25 words
A building unit is claimed in claim 1 wherein said skeleton structures comprises slender frame members, and means for detachably connecting the frame members together.
Claim 4
Dependent Claim
30 words
A building unit as claimed in claim 2 wherein said skeleton structures includes generally horizontal support members extending about the top thereof, said panels being suspended from said support members.
Claim 5
Dependent Claim
54 words
A building unit as claimed in claim 2 wherein said skeleton structures include a plurality of vertical, spaced-apart column members, a roof on the building unit, the roof having a plurality of arch members, each arch extending between, and attached to, opposed pairs of column members in the side walls of the skeleton structures.
Claim 6
Dependent Claim
31 words
A building unit as claimed in claim 4 including a ceiling, the ceiling having a plurality of joist members, each extending between and attached to the ends of an arch member.
Claim 7
Dependent Claim
24 words
A building unit as claimed in claim 1, wherein said resilient means are mounted through the outer skins of said panels between adjacent webs.
Claim 8
Dependent Claim
180 words
A knock-down portable building unit for use as a court for off-the-wall games requiring at least one wall suitable for the bouncing off of a ball, said building comprising: a frame made up of removably interconnected rigid slender members extending in three planes defining one end skeleton structure and two side skeleton structures extending from said end structure and heavy sill members intended to rest unattachedly on the ground and to which said skeleton structures are removably secured from their lower ends; modular panel members fixed to and inwardly of said skeleton structures over the whole surfaces thereof whereby said structures, sills and panels form a playing enclosure; wherein said panels of at least one of said walls has an inner surface thereof which is flat, continuous, devoid of projecting parts and made of a material having a ball-bouncing property, and wherein said panels of said one wall are made of plastics material defining inner cells and wherein ballast material is contained in said cells to weight said panels down and increase the bouncing property of said one flat surface.
Claim 9
Dependent Claim
180 words
A knock-down portable building unit for use as a court for off-the-wall games requiring at least one wall suitable for the bouncing off of a ball, said building comprising: a frame made up of removably interconnected rigid slender members extending in three planes defining one end skeleton structure and two side skeleton structures extending from said end structure and heavy sill members intended to rest unattachedly on the ground and to which said skeleton structures are removably secured from their lower ends; modular panel members fixed to and inwardly of said skeleton structures over the whole surfaces thereof whereby said structures, sills and panels form a playing enclosure; wherein said panels of at least one of said walls has an inner surface thereof which is flat, continuous, devoid of projecting parts and made of a material having a ball-bouncing property, and wherein said panels of said one wall are made of plastics material defining inner cells and wherein ballast material is contained in said cells to weight said panels down and increase the bouncing property of said one flat surface.
Claim 10
Dependent Claim
