Abstract

Fences and lattices are formed from a single sheet of corrugated-like plastic material comprising a pair of substantially flat sheets spaced apart by spacers that are in parallel and have the same width to form between the flat sheet a series of parallel channels. The fences include a pair of spaced apart cross supports and a series of pickets that intersect the cross supports. The cross supports and pickets all lie in substantially the same plane. The lattices include a plurality of slats intersecting each other at an angle of 90°. These slats all lie in substantially the same plane and the channels are at an angle of 45° with respect to the longitudinal axis of individual slats.

Claims

1. A fence comprising

a pair of spaced apart cross supports and a series of pickets that intersect said cross supports,

said cross supports and pickets lying in substantially the same plane and being formed from a single sheet of substantially corrugated plastic material.

2. The fence of claim 1 where the sheet of substantially corrugated plastic material comprises a pair of substantially flat members spaced apart by spacers that are in parallel and have the same width to form between the flat members a series of parallel channels.

3. The fence of claim 2 where the parallel channels extend lengthwise along the length of the pickets.

4. The fence of claim 1 where the cross supports and pickets are formed by die cutting the sheet of corrugated-like plastic material.

5. The fence of claim 1 where the sheet of substantially corrugated plastic material has a thickness of from ⅛

to ⅜

inch.

6. The fence of claim 1 where the cross supports and pickets intersect each other at an angle of 90°

, and the pickets are at an angle of 90°

with respect to ground level.

7. A lattice comprising a plurality of slats intersecting each other, said slats lying in substantially the same plane and being formed from a single sheet of substantially corrugated plastic material.

8. The lattice of claim 7 where the sheet of corrugated-like plastic material comprises a pair of substantially flat members spaced apart by spacers that are in parallel and have the same width to form between the flat members a series of parallel channels.

9. The lattice of claim 8 where the slats intersect each other at an angle of 90°

, the channels are at an angle of 45°

with respect to the longitudinal axis of individual slats, and the slats are at an angle of 45°

with respect to ground level.

10. The lattice of claim 7 where the slats are formed by die cutting the sheet of substantially corrugated plastic material.

11. The lattice of claim 7 where the sheet of substantially corrugated plastic material has a thickness of from ⅛

to ⅜

inch.

12. A structure having intersecting strips in substantially the same plane and wherein the structure is made from a single sheet of substantially corrugated plastic material comprising a pair of substantially flat members spaced apart by spacers that are in parallel and have the same width to form between the flat members a series of parallel channels, said strips being formed by cutting the sheet using a rule-type die.

13. A method of making a fence comprising the steps of cutting a single sheet of substantially corrugated plastic material to form from the sheet a pair of cross supports and intersecting pickets that are in the same plane and where the cross supports and pickets intersect each other at an angle of 90°

, and the pickets are at an angle of 90°

with respect to ground level.

14. A method of making a lattice comprising cutting a single sheet of substantially corrugated plastic material to form intersecting slats that are in the same plane and where the slats intersect each other at an angle of 90°

, and are at an angle of 45°

with respect to ground level.

15. A method of constructing a fence including the steps of

providing at least two fence sections where each fence section comprises a plurality of slats intersecting each other, said slats lying in substantially the same plane and being formed from a single sheet of substantially corrugated plastic material where the substantially corrugated plastic material comprises a pair of substantially flat members spaced apart by spacers that are in parallel to form between the flat members a series of parallel channels, each fence section having side edges,

positioning the two fence sections next to each other with their respective side edges abutting each other and the fence sections oriented substantially at a right angle to ground level, and

providing a connector that has a pair of parallel legs and inserting one leg into a channel in each fence section.

16. The method of claim 15 where the connector is U-shaped.

17. The method of claim 15 where the connector legs are substantially longer than the height of the fence sections and legs have lower ends which are forced into the ground after passing through the channels.

18. The method of claim 16 where the fence sections are of equal height.

19. A method of making a structure having intersecting strips comprising the step of

(a) providing a single sheet substantially corrugated plastic material comprising a pair of substantially flat members spaced apart by spacers that are in parallel and have the same width to form between the flat members a series of parallel channels, and

(b) with a rule-type die cutting the single sheet of substantially corrugated plastic material to form therein strips that are in substantially the same plane.
