Claim 1
Independent Claim
341 words
A shower cabinet which is collapsIble so that when not in use it occupies a space smaller than the front-to-back depth required to accomodate a person taking a shower but can readily be opened to provide a space to accomodate such a person, said cabinet including a back structure of smaller depth than said space, a tray pivotally attached to the back structure and movable from a collapsed vertical position adjacent the back structure to a forwardly extended approximately horizontal position near floor level, two side walls pivotally attached to the back structure on vertical axes and movable from collapsed positions adjacent the back structure to forwardly extended positions approximately at right angles to the back structure, an overhead transverse horizontal support member, foldable linkage means including a first linkage mounted on the cabinet and a second linkage hinged thereto and carrying said member, said linkage means being arranged to convey said member from the back of the cabinet to the front of the cabinet by extending the linkage means from a position adjacent the back structure where the linkages are folded on each other into a forwardly extended approximately horizontal overhead position which is approximately in the same transverse vertical plane as the front edge of the extended tray whereby the forward and retracted positions of said horizontal support member are in a common horizontal plane, means to prevent escape of water between the two side walls when extended and the tray, a front closure member having its top edge carried by said support member and movable thereby from a retracted position adjacent the back structure to a position at the front of the cabinet in the extended position in which the front closure member is supported in both forward and retracted positions in approximately fully extended condition vertically, and connecting means operatively connecting the foldable linkage means with the tray whereby movement of the tray to its extended and retracted positions automatically moves the linkage means to bring the front closure member to its extended and retracted positions respectively.

Claim 5
Dependent Claim
28 words
A cabinet as claimed in claim 1, wherein the overhead support member is made of a plurality of sheets of rigid material hinged together at their transverse edges.
Claim 6
Dependent Claim
26 words
A cabinet as claimed in claim 1, wherein the overhead support member is made of a single sheet of flexible material carried by said linkage means.
Claim 7
Dependent Claim
92 words
A cabinet as claimed in claim 1, wherein the linkage means includes pivot means carried transversely in the back structure, a lever pivoted at its rear end on said pivot means, a first link, said lever being pivotally attached at its other end to the rear end of said first link, the forward end of said first link being attached to the forward edge of the overhead support member, and a second link pivoted at its rear end to the back structure and pivoted at its forward end to the first link.
