Abstract: The present invention is a multi-wall sheet made of a plastic with a high shear modulus intended to provide physical protection, structural support, and thermal insulation in applications where a small bending radius for the multi-wall plastic sheet is desired. The multi-wall configuration includes a generally flat outer single sheet and a contoured inner single sheet separated by a series of ribs of similar plastic material to form a connected row of longitudinal cavities or “channels”. The inner wall is contoured in a concave manner to form a relief between each rib. When the multi-wall sheet is flexed, each relief distorts to minimize stress in the transverse direction while maintaining high rigidity in the longitudinal direction. In another embodiment of the present invention, multiple single sheets separated by ribs and contoured similarly to that of the inner wall are added between the contoured inner wall and non-contoured outer wall.

Abstract: The present invention is a twin-wall rigid plastic sheet intended to provide protection and insulation in applications where a small bending radius for the twin-wall plastic sheet is desired. The twin-wall configuration includes a smooth or flat outer single sheet and a contoured inner single sheet separated by a series of similar plastic ribs to form a connected row of longitudinal cavities or “channels”. The inner wall is contoured in a concave manner to form a relief between each rib. When the twin-wall sheet is flexed, each relief distorts to minimize stress in the transverse direction while maintaining high rigidity in the longitudinal direction. In another embodiment of the present invention, multiple single sheets separated by ribs and contoured similarly to that of the inner wall are added between the contoured inner wall and smooth outer wall.

Abstract: The present invention is a compact plant enclosure intended for use in locations with peripheral space restrictions. The top and one side of the enclosure form a continuous curved face which consists of multiple translucent flexible access panels that can be slid along guide channels incorporated into the sides of the curved frame components on either side of the flexible panels. The guide channels and flexible panel edges may incorporate retention features that limit the lateral movement of the flexible access panels. The opposing wall may include a single translucent vertical panel or multiple vertical access panels. The remaining two vertical sides of the plant enclosure each consist of a fixed, translucent rigid panel. In another embodiment of the present invention, multiple distinct intermediate segments of the enclosure are defined by interstitial curved and vertical frame components supporting adjacent sets of flexible access and opposing vertical panels.

Abstract: A stationary container with straight, vertical walls and an open top has a bottom frame with an array of holes through which closely packed support cells can slide so that the base of the container roughly contours to the surface on which it is set while maintaining a level top surface. This arrangement allows the load of a contained fluid material to be applied normal to the top of each support cell, distributing the vertical load over multiple points between the bottom of the container and the load-bearing surface on which the container is set. The support cells may be solid, hollow, or have openings to allow fluid to pass between the interior and exterior of the container. The container walls are vertical and attach to adjustable corner posts.
