Abstract
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.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
91 words
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.
Claim 2
Dependent Claim
91 words
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.
Claim 3
Dependent Claim
39 words
The panel as in claim 1 wherein the hollow plastic extrusions have a cross-sectional, internal dimension and the corresponding solid extrusions have a cross-sectional, external dimension, said external dimension being at least about 1/8" smaller than said internal dimension.
Claim 4
Dependent Claim
25 words
The panel as in claim 1 further comprising a plurality of crossbars, each crossbar extending across the internal region and attached to the peripheral structure.
Claim 5
Dependent Claim
81 words
The panel as in claim 3 wherein: the peripheral structure forms a quadrilateral and has first and second pairs of opposed hollow plastic extrusions, each hollow plastic extrusion of one pair being connected by connecting means to both hollow plastic extrusions of the other pair, each hollow plastic extrusion of the first and second pairs having a corresponding solid extrusion therewithin, the connecting means permitting liquid communication between the spaces of the first and second pairs of opposed hollow plastic extrusions.
Claim 6
Dependent Claim
16 words
The panel as in claim 4 wherein the connecting means includes four L-shaped, hollow plastic members.
Claim 7
Dependent Claim
36 words
The panel as in claim 5 wherein the peripheral structure has transverse passageways interconnecting the spaces of the first and second pairs of hollow plastic extrusions and the external or internal region of the peripheral structure.
Claim 8
Dependent Claim
22 words
The panel as in claim 4 wherein the hollow plastic extrusions are polyvinyl chloride tubes and the solid extrusions are wooden rods.
Claim 9
Dependent Claim
26 words
The panel as in claim 7 wherein the wooden rods are impregnated with a water soluble or miscible compound having a freezing point below 0° C.
Claim 10
Dependent Claim
107 words
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.
Claim 11
Dependent Claim
107 words
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.
Claim 12
Dependent Claim
90 words
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.
