    • A solar structure, and more particularly a greenhouse, comprising a framework formed from frame members (20, 20a) and a flexible cover (26) having portions (28) of varying optical density (A, B, C) along its length, and wound between a pair of opposed spools (24) mounted on respective sides of the framework such that the cover is wound from one spool to the opposed spool. The cover is constrained to move over rollers (22) extending longitudinally of the framework, and the edges of the cover are received to move within slots (25) formed in the edges of the frame members. The flexible cover (26) may be formed as panels (A, B and C) having adjacent lengths of material (28) of differing optical densities. The lengths (28) are arranged sequentially along the cover (26) and may be transparent, translucent or opaque. Some of the lengths may have heat insulating and/or heat reflective properties and some may be foraminous to provide regions of different optical density and ventilation. The longitudinal ends (30) of adjacent lengths (28) are joined by a seam. Alternatively the flexible cover (26) may be formed from a single length of material having a different optical density along its length.

    • 一种太阳能结构,特别是温室,其包括一个框架元件(20,20a)和一个柔性罩(26)具有部分(28)在其长度方向上不同的光密度的形成,缠绕的对之间 相对的线圈(24)安装在框架的相应侧上,使得盖可以从一个线圈传递到另一个线圈。 盖的运动受到沿框架长度方向延伸的辊子(22)的限制,并且盖子的边缘在框架构件的边缘中的狭槽(25)中移动。 柔性盖(26)可以采取具有不同光学密度的相邻纵向材料带(28)的面板(A,B和C)的形式。 这些材料带(28)在盖(26)的长度方向上连续延伸,并且可以是透明的,半透明的或不透明的。 有些可能具有绝缘和/或热反射特性,其他可能有创造光密度区域和不同程度的通风的区域。 相邻条带(28)的纵向端部(30)通过接缝连接。 或者,柔性盖(26)可以由沿其长度具有各种光学密度的单条材料形成。
