Abstract
A lightweight panel is provided that may be used as a gate, a fence section, or the base of a temporary carport. The panel may be selectively made more massive, and includes a peripheral structure comprised of hollow plastic extrusions having corresponding solid extrusions disposed therein while leaving sufficient space to permit a liquid to be interposed within the hollow plastic extrusions when desired.
Claims10
A panel comprising:
- a peripheral structure defining an internal region and an external region and having at least one hollow plastic extrusion and at least one solid extrusion corresponding to the hollow plastic extrusion, the corresponding solid extrusion disposed within the hollow plastic extrusion while leaving sufficient space to permit a liquid to be interposed in the hollow plastic extrusion;
- and,
- means operatively associated with the hollow plastic extrusion for selectively permitting a liquid to be interposed into the hollow plastic extrusion adjacent the corresponding solid extrusion and selectively drained therefrom.
A gate or fence section comprising:
- a rectangular structure defining a periphery and having a first pair of substantially parallel plastic tubes, a second pair of substantially parallel plastic tubes, four L-shaped hollow plastic members interconnecting the first and second pairs of tubes, and reinforcing rods disposed within the first and second pairs of tubes, the rods of sufficiently smaller size than the hollow plastic members as to leave a chamber interior to and extending around the periphery;
- means operatively associated with the chamber for selectively interposing water into the chamber and selectively draining the water therefrom, and,
- means within the periphery for bracing the rectangular structure.
A portable carport frame comprising:
- a base having a pair of opposed hollow plastic extrusions and a plurality of solid extrusions disposed within each of the opposed hollow plastic extrusions while leaving sufficient space to permit a liquid to be interposed in the hollow plastic extrusions;
- means operatively associated with the hollow plastic extrusions for selectively permitting a liquid to be interposed into the hollow plastic extrusions;
- and,
- at least one arm member pivotally connected to the base and positionable into an upright position perpendicular with respect to the base.
