Abstract
Abstract A collapsible overhead enclosure or shelter, especially for swimming pools or to serve as garages, storage sheds or the like. The enclosure consists of a pair of spaced base members and a plurality of shaped struts spanning between the base members mounted thereto at hinge points for swinging movement between a collapsed position and fan-like erected position. The hinge points are arranged in an arcuate pattern on each base member. A sheet of flexible material is supported by the struts and provides an overhead shelter or enclosure when the struts are in their fan-like erected positions. Alternate embodiments include the uppermost mounted strut being articulated at opposed locations so that it may lie flat on the ground when the struts are erected. Further alternate embodiments include reciprocal mounting for the base members whereby they may be moved to one location to collapse the shelter and to avoid interference with a swimming pool or other area. In still another embodiment, a plurality of pairs of base members provide support for an elongated shelter, being movable from a first location in which the pairs of base members are spaced apart and the struts support an erected shelter to a second location with pairs of base members moved together and the struts stacked in a collapsed condition.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
160 words
A collapsible shelter comprising: a pair of spaced base members; a plurality of shaped struts spanning between said base members, said struts mounted at hinge points on said base members for swinging movement between a collapsed position and an erected position, said hinge points arranged in an arcuate pattern on each base member along a line extending from adjacent the bottom edge of said base member upward and curving through an arc of approximately 90°; a sheet of flexible material supported on said plurality of shaped struts, so that when said struts are in said collapsed position all of said struts lie horizontally on top of one another and generally parallel to one another with the sheet folded therewith, and when said struts are in said erected position they assume a fan-like relationship, extending radially outward from said base members, and said sheet is stretched across said struts to provide a shelter in accordance with the shapes of said struts.
Claim 2
Dependent Claim
160 words
A collapsible shelter comprising: a pair of spaced base members; a plurality of shaped struts spanning between said base members, said struts mounted at hinge points on said base members for swinging movement between a collapsed position and an erected position, said hinge points arranged in an arcuate pattern on each base member along a line extending from adjacent the bottom edge of said base member upward and curving through an arc of approximately 90°; a sheet of flexible material supported on said plurality of shaped struts, so that when said struts are in said collapsed position all of said struts lie horizontally on top of one another and generally parallel to one another with the sheet folded therewith, and when said struts are in said erected position they assume a fan-like relationship, extending radially outward from said base members, and said sheet is stretched across said struts to provide a shelter in accordance with the shapes of said struts.
Claim 3
Dependent Claim
40 words
The collapsible shelter of claim 1 wherein the one of said struts mounted at the top of said arcuate pattern of hinge points has an angled section to lie flat on the ground or other surface supporting said base members.
Claim 4
Dependent Claim
38 words
The collapsible shelter of claim 1 wherein the one of said struts mounted at the top of said arcuate pattern of hinge points is articulated to lie flat on the ground or other surface supporting said base members.
Claim 5
Dependent Claim
62 words
The collapsible shelter of claim 1 wherein the one of said struts mounted at the top of said arcuate pattern of hinge points has first and second segments, said first segments extending between said hinge points and said second segment, said second segment angled relative to said first segment for lying flat on the ground or other surface supporting said base members.
Claim 6
Dependent Claim
30 words
The collapsible shelter of claim 1 further including a pair of spaced parallel tracks for mounting said spaced pair of base members for reciprocal movement between first and second locations.
Claim 7
Dependent Claim
28 words
The collapsible shelter of claim 4 wherein first segments are joined to said second segment by means for articulation of said second segment relative to said first segments.
Claim 8
Dependent Claim
28 words
The collapsible shelter of claim 6 wherein said articulation means comprises a spring generally biasing said second segment to lie in the same plane as said first segments.
Claim 9
Dependent Claim
42 words
The collapsible shelter of claim 5 wherein when said struts are in said erected positions at said first location, said second location is spaced from said first location in the direction at which the strut mounted at the lowermost hinge point extends.
Claim 10
Dependent Claim
20 words
The collapsible shelter of claim 8 further comprising means for moving said base members between said first and second locations.
Claim 11
Dependent Claim
42 words
The collapsible shelter of claim 9 wherein said moving means comprises means biasing said base members toward said second location and means for driving said base members from said second location to said first location against the urging of said biasing means.
Claim 12
Dependent Claim
176 words
A collapsible shelter comprising: a plurality of opposite pairs of spaced base members; a plurality of shaped struts spanning between opposite pairs of base members, said struts mounted at hinge points on said base members for swinging movement between a collapsed position and an erected position, said hinge points arranged in an arcuate pattern on each base member wherein the arcuate pattern of successive pairs of base members is elevated whereby the lowest hinge point of a second pair of base members is elevated above the highest hinge point of a first pair of said base members and so on whereby said collapsed position is characterized by said struts lying horizontally on top of one another and generally parallel to one another; a sheet of flexible material supported on said plurality of shaped struts, so that when said struts are in said collapsed position, said sheet folds therewith, and when said struts are in said erected positions, said sheet is stretched across said struts to provide a shelter in accordance with the shapes of said structs.
