Description

BACKGROUND OF THE INVENTION

Portable fencing systems are desirable to customize a fenced-in area in a quick and efficient manner so that the fenced-in area could be set up in a variety of configurations to fit a multitude of applications. The resultant fenced-in area could be used, for example, in indoor or outdoor compounds, at construction/roofing sites, for seasonal display items, for garden centers, for outdoor special events, for crowd control, for repair and renovation area, for property fencing for tool rooms, etc.

One known portable fencing system includes a plurality of fence sections which have fence walls made, for example, of galvanized steel with the wall sections having legs extending downwardly from the wall section. Base blocks are positioned at suitable locations. The base blocks include holes for receiving the legs. In this known system, the base blocks are concrete blocks which weigh, for example, 60 to 90 pounds each, thus allowing the blocks to be installed on any surface and because of its weight providing a stable mounting of the fenced sections.

A disadvantage with the base blocks of the known portable fencing system is that such blocks are not only very heavy but because the blocks are made of concrete, if the blocks should be dropped they would tend to crack.

SUMMARY OF THE INVENTION

An object of this invention is to provide a portable fencing system which incorporates base blocks having improved structure over the above indicated known system.

A further object of this invention is to provide such a system which incorporates all of the advantages of the above known system while eliminating some of its disadvantages.

In accordance with this invention the base block is made at least partially from an outer skin which forms a hollow chamber. The hollow chamber includes a heavy filler material such as water, sand or concrete. Thus, if the block is accidentally dropped the outer skin will remain intact and would still include the heavy filler material within its chamber.

DETAILED DESCRIPTION

The present invention relates to improvements in portable fencing systems of the type which include a plurality of fence sections. As shown in FIGS. 4-5 the portable fencing system 10 includes a plurality of fence sections 12 made of any suitable construction. Preferably the fence structures are of mesh-type structure made from durable hot dipped galvanized steel construction to withstand all weather. Thus, each fence section 12 includes a mesh type wall portion 13. The ends of each fence section include rigid posts 15 which extend below the wall 13 to form legs 14 with each leg 14 being inserted into a corresponding hole in a base block 16, as shown in phantom in FIGS. 2-3. The adjacent fence sections 12 may be secured together in any suitable manner, such as by wall clamps 18 which permit pivotal movement of the fence sections with respect to each other. If desired, a wheel 20 could be provided for one or more sections to permit that section to function as a gate.

In operation when it is desired to provide a fenced area the general area would be marked out and base blocks 16 would be placed at the proper locations corresponding to the fence length. Each base block 16 includes a set of two center holes 22 and a set of two end holes 24. The blocks would be located so that the appropriate set of center holes or end holes is positioned to receive the corresponding legs 14 of the fence sections. The fence sections would then be installed by inserting the legs 14 into the appropriate holes 22 or 24. Adjacent sections would be secured together through use of the clamps 18.

The invention is directed primarily to the construction of the base blocks 16. As shown in FIGS. 1-3, each base block 16 is made at least partially from an outer skin material 26 which forms a hollow chamber 28. The skin material is made from a sufficiently durable, rigid material, such as PVC, so as to withstand rough use. In a preferred practice of the invention the entire block 16 could be made of the plastic skin material. Thus, the block itself is relatively lightweight.

The hollow chamber 28 includes a fill opening 30 covered by a removable closure 32 which could be screwed into the opening or fit into the opening 30 in any suitable manner. Preferably, the closure 32 is a thin welded fitting for filling or emptying the chamber 28. Closure 32 would be removed to expose the chamber and the chamber would be at least partially filled with a heavy filler material 40 such as water, sand or concrete. Where concrete is used as the filler material the concrete could be mixed and poured in situ for being inserted in the chamber 28. The closure 32 would then be reattached to cover fill opening 30. As a result, a heavy block results which provides stability in anchoring the fence sections. If desired, the blocks 16 could be prefilled or could be filled at the site of the fencing location.

As shown in FIGS. 1-3 the block 16 includes a handle 34 which spans the set of holes 22,24. Handle 34 is located generally along the longitudinal axis or centerline of block 16 and is located in the half of the block opposite the half of the block having the chamber 28. Chamber 28 includes an external depression or recess 36 so as to accommodate a second handle 38 that spans the recess in a direction perpendicular to handle 34. Thus, the two handles 34,38 provide a ready manner for easily carrying and properly placing the block 16. Preferably, the handles 34,38 are made of tubular form and likewise could be made of PVC material. The provision of the two handles 34,38 makes the moving and dumping of the chamber much easier in a practice of the invention.

As best shown in FIG. 2 the upper surface of block 16 on its half which contains the chamber 28 is downwardly inclined so as to minimize any interference with the placement of the legs 16 in the proper holes 22 or 24.

The block 16 may have an overall length of 27 inches and a maximum height at the holes 22,24 of 5.75 inches. Except for the filler material the entire block 16 could be made of PVC or other material used to form the outer skin.

As best illustrated in FIGS. 4-5 the provision of two sets of holes 22,24 provides the user with selectivity in the placement of the fence sections so that either set of holes 22 or 24 may be used as appropriate.

The present invention represents a marked improvement over prior portable fencing systems which utilize base blocks made of concrete. Even where the filler material 40 in the chamber 28 is itself made of concrete, if the block 16 should be dropped and the concrete filler material cracked, the filler material 40 would still be retained in the chamber 28 so as to continue to function in the intended manner. Where the filler material is of a flowable nature, such as water or sand, no change results from dropping the block 16.
