Abstract
Abstract A structural arrangement is provided which is particularly useful in connection with solar greenhouses. The structural member is suitable for use in a parallel arrangement of the same particularly for the purpose of providing controlled shading. The structural member is provided as a hollow bar of elongated form provided with at least one longitudinally extending track channel having a relatively narrow longitudinally extended slot-mouth. The bar may be provided with two such channels and these channels are substantially circular in cross-section with the mouths defining reentrant angles therewith. In a solar greenhouse, members of the above type support a glazing with a curved-eave section, the bars being curved to shape and the channels therein accommodating the bulbous lateral edges of shades which are retained therein. The shades are transferred from one roller in the direction of a second roller. The rollers may be provided with internal motors which rotate the same, although the arrangement disclosed is susceptible of being operated manually as well and additionally in conjunction with one or more spring loaded rollers. The arrangement is also suitable for selectively extending shields against wind and other such elements including rain and snow by the raising up of walls constituted by transparent sheets of plastic.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
275 words
A solar greenhouse construction comprising glazing, support means to support said glazing in a combination to define an at least partly enclosed space, said glazing being permeable to solar radiation to allow said radiation to pass into said space, shade means in said space and adapted for being positioned adjacent at least part of said glazing to intercept at least part of the radiation passing through said glazing, said support means including at least two spaced and parallel glazing bars supporting and spanned by at least a part of said glazing, each of said glazing bars being provided with at least one channel, the channels of said bars being aligned in parallel, said shade means extending between one said channel of one of said bars and one said channel of the other of said bars, a horizontal sill positioned at the botton of said glazing bars, and means contained within said sill and coupled to said shade means to aid in positioning the same, said glazing including a curved portion, said support means and said channels including curved portions extending along the curved portion of the glazing, said shade means including parallel bulbous lateral peripheries engaged in respective of said channels, said channels being provided with relatively narrow slot-type mouths opening from said bars whereby to admit the entry of said shade means and to entrap the bulbous peripheries in said channels, said sill being open in alignment with said channels and said shade means including cables extending through and beyond said bulbous peripheries, said cables extending through said channels and into said sill and being connected to the means contained within the said sill.
Claim 2
Dependent Claim
275 words
A solar greenhouse construction comprising glazing, support means to support said glazing in a combination to define an at least partly enclosed space, said glazing being permeable to solar radiation to allow said radiation to pass into said space, shade means in said space and adapted for being positioned adjacent at least part of said glazing to intercept at least part of the radiation passing through said glazing, said support means including at least two spaced and parallel glazing bars supporting and spanned by at least a part of said glazing, each of said glazing bars being provided with at least one channel, the channels of said bars being aligned in parallel, said shade means extending between one said channel of one of said bars and one said channel of the other of said bars, a horizontal sill positioned at the botton of said glazing bars, and means contained within said sill and coupled to said shade means to aid in positioning the same, said glazing including a curved portion, said support means and said channels including curved portions extending along the curved portion of the glazing, said shade means including parallel bulbous lateral peripheries engaged in respective of said channels, said channels being provided with relatively narrow slot-type mouths opening from said bars whereby to admit the entry of said shade means and to entrap the bulbous peripheries in said channels, said sill being open in alignment with said channels and said shade means including cables extending through and beyond said bulbous peripheries, said cables extending through said channels and into said sill and being connected to the means contained within the said sill.
