Claim 1
Independent Claim
244 words
In a collapsible building structure having a plurality of vertical pillars a. a pair of spaced parallel rails, each rail comprising a generally vertical section and a flange on the top edge of and perpendicular to said vertical section, said flange extending horizontally beyond the opposite sides of said vertical section forming opposed right angles between the bottom surfaces of said flange and the opposite surfaces of said vertical section, and b. means movably supporting each of said pillars on one of said rails comprising a centrally located main roller mounted for rotation about a horizontal axis, the periphery thereof contacting the top surface of said flange and a pair of opposed guide rollers adjacent opposite sides of the vertical section of said rail and below said flange, each of said guide rollers having axially spaced sharp cylindrical edges at opposite sides thereof, being mounted for rotation about an axis at an acute angle with respect to the adjacent surfaces of both said vertical section and said flange, and being located such that said sharp cylindrical edges engage said adjacent surfaces of said vertical section and flange respectively, the cylindrical surface of each of said rollers between said sharp edges being spaced from the juncture of said vertical section and flange, c. whereby the area of contact between each guide roller and said rail is minimized and said pillars are movably secured to said rails and may be moved along said rails more easily.

Claim 4
Dependent Claim
183 words
In a collapsible building structure having a plurality of vertical pillars a. a pair of spaced parallel rails, each rail comprising a flange in a generally horizontal plane and having a flat top surface and opposite longitudinal edges which are free and unsupported, and b. means movably supporting each of said pillars on one of said rails comprising a centrally located main roller mounted for rotation about a horizontal axis, the periphery thereof contacting the top surface of said flange and a pair of opposed guide rollers adjacent said opposite edges respectively of said flange, each of said guide rollers having a concave peripheral surface and being mounted for rotation about an axis at an acute angle with respect to the plane of said flange such that said guide roller extends beneath the respective edge of said flange and its concave peripheral surface engages the respective edge of said flange, c. whereby the area of contact between each guide roller and said rail is minimized and said pillars are movably secuRed to said rails and may be moved along said rails more easily.
Claim 5
Dependent Claim
183 words
In a collapsible building structure having a plurality of vertical pillars a. a pair of spaced parallel rails, each rail comprising a flange in a generally horizontal plane and having a flat top surface and opposite longitudinal edges which are free and unsupported, and b. means movably supporting each of said pillars on one of said rails comprising a centrally located main roller mounted for rotation about a horizontal axis, the periphery thereof contacting the top surface of said flange and a pair of opposed guide rollers adjacent said opposite edges respectively of said flange, each of said guide rollers having a concave peripheral surface and being mounted for rotation about an axis at an acute angle with respect to the plane of said flange such that said guide roller extends beneath the respective edge of said flange and its concave peripheral surface engages the respective edge of said flange, c. whereby the area of contact between each guide roller and said rail is minimized and said pillars are movably secuRed to said rails and may be moved along said rails more easily.
Claim 6
Dependent Claim
56 words
A collapsible building structure as defined in claim 3 wherein said support means further comprises a. a pair of spaced brackets between which is mounted said main roller, b. the lower part of said brackets below said main roller extending symmetrically outwardly, and c. said guide rollers being mounted on said lower part of said brackets.
