Abstract
Abstract A movable roof structure for a patio, building, swimming pool or the like is comprised of a plurality of roofing units which are in an overlapping shingle-like arrangement. The roofing units are telescopically movable with respect to each other between a closed position where they partially overlap each other and an open position where they are substantially stacked one on top of the other. Each roofing unit includes a pair of end extrusions and an elongated intermediate extrusion. Each extrusion carries roof panels on the side edges thereof so that said panels are joined end to end in the direction of the width of the roof. The extrusions also carry wheel and track members which cooperate with the extrusion immediately above and below so that the roofing units are movable. A power driven chain or the like moves the roofing units between their closed and open positions.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
152 words
A movable roof structure comprising: a plurality of roofing units, each of said roofing units being comprised of at least one extrusion member and a pair of roofing panels, one of each of said pair of panels being connected to either side of said extrusion member; wheel and track means carried by each of said extrusion members and being in cooperative relationship with an adjacent extrusion member of an adjacent roofing unit, each of said track means including means for preventing the wheel means from the next adjacent roofing unit from moving upwardly away from each said track means; said roofing units being movable in telescoping relationship with respect to each other whereby said roof can be moved between an open position and a closed position and including spring biased detent means for maintaining said roofing units in said open and in said closed positions, and means for moving said roofing units.
Claim 2
Dependent Claim
152 words
A movable roof structure comprising: a plurality of roofing units, each of said roofing units being comprised of at least one extrusion member and a pair of roofing panels, one of each of said pair of panels being connected to either side of said extrusion member; wheel and track means carried by each of said extrusion members and being in cooperative relationship with an adjacent extrusion member of an adjacent roofing unit, each of said track means including means for preventing the wheel means from the next adjacent roofing unit from moving upwardly away from each said track means; said roofing units being movable in telescoping relationship with respect to each other whereby said roof can be moved between an open position and a closed position and including spring biased detent means for maintaining said roofing units in said open and in said closed positions, and means for moving said roofing units.
Claim 3
Dependent Claim
16 words
The invention as claimed in claim 1 wherein said roof structure is inclined to the horizontal.
Claim 4
Dependent Claim
18 words
The invention as claimed in claim 2 wherein said extrusion members are inclined parallel to said roof structure.
Claim 5
Dependent Claim
21 words
The invention as claimed in claim 3 wherein said roofing units are arranged in overlapping relationship with respect to each other.
Claim 6
Dependent Claim
38 words
The invention as claimed in claim 4 wherein the lower edge of each roofing unit overlies the upper edge of the roofing unit immediately below it on the incline when said roof structure is in its closed position.
Claim 7
Dependent Claim
29 words
