Abstract

A self-supporting fence of indefinite length is formed of a succession of fence units each having at least one vertically extending post member and at least one horizontally extending rail member integral with the post member. Continuous compliant strands extend horizontally through the rail member to flexibly link the units. The fence units are preferably formed of a high impact plastic and have a cored-out construction. The linking strands are preferably of braided fiber and embedded in each rail member. Some post members have downwardly projecting stake portions for supporting the fence. [USPTO]

Claims

What is claimed and desired to be secured by Letters Patent is:

1. A self-supporting and laterally-flexible fence comprising a longitudinal succession of fence units,

A. each pair of adjacent units defining between them at least first and second vertically-spaced gap portions,

said first gap portions of at least plural fence units being horizontally aligned with one another,

and said second gap portions of at least plural fence units being horizontally aligned with one another,

each fence unit being of substantially rigid one-piece molded construction and having at least one substantially rigid fence member extending vertically and at least two substantially rigid fence members extending horizontally from one end only of said unit, said fence members of adjacent units defining said first and second gap portions between said units, and

B. at least first and second flexible compliant strands, each of which extends longitudinally along plural fence units, each strand being embedded within members of each fence unit upon the molding thereof and spanning gap portions to secure said units together and provide said lateral flexibility.

2. A self-supporting fence of indefinite length having flexibly interconnected fence units comprising

A. a succession of separate fence units having gap portions therebetween and each of which has a unitary structure of molded plastic material with at least a substantially rigid vertical post member integral with a pair of first and second vertically spaced and substantially rigid horizontally-extending elements, each said post member having a substantially planar web portion and at least first and second integrally formed flange portions extending generally perpendicular to said web portion and horizontally along the fence unit, said first elements of successive fence units being aligned with one another and said second elements of successive fence units being aligned with one another, and

B. at least first and second continuous flexible strands interconnecting adjacent fence units, each strand extending between at least horizontally-extending elements and spanning said gap portions, said first and second strands being embedded in the plastic material of said fence units and respectively extending along and secured to said first and second flange portions of post members and to said aligned first elements and said aligned second elements.

3. A self-supporting fence of indefinite length having flexibly interconnected fence units comprising

A. a succession of separate fence units having gap portions therebetween and each of which has a unitary structure of molded plastic material with at least a substantially rigid vertical post member integral with a pair of first and second vertically spaced and horizontally extending substantially rigid rail elements, said post member and rail elements each having a substantially planar web portion and an integrally formed flange portion extending at least longitudinally of said web portion and generally perpendicular to said web portion, and said first rail elements of successive fence units being aligned with one another and said second rail elements of successive fence units being aligned with one another, and

B. at least first and second flexible link members interconnecting adjacent fence units, each link member extending from at least one rail element and spanning one said gap, said first link members and said second link members being formed by first and second continuous strand means embedded in the plastic material of said fence units and respectively extending along and secured to horizontally-extending flange portions of said aligned first rail elements and of said aligned second rail elements.

4. A self-supporting fence of indefinite length having flexibly interconnected fence units comprising

A. a succession of fence units closely spaced apart by gaps and each of which has a unitary structure of molded plastic material with at least a substantially rigid vertical post member integral with a pair of first and second vertically spaced and substantially rigid horizontally-extending elements, said first elements of successive fence units being aligned with one another and said second elements of successive fence units being aligned with one another,

B. at least first and second flexible link members interconnecting adjacent fence units, each link member extending from at least one said element and spanning one said gap, said first link members and said second link members being formed by first and second continuous strand means embedded in the plastic material of said fence units and respectively extending along and secured to said aligned first elements and said aligned second elements, and

C. a flashing of said plastic material extending across each of at least a plurality of said gaps.

5. A fence according to claim 3 in which said rail flange portion adjacent said post extends to and is integral with said post web portion.

6. A self-supporting and laterally-flexible fence comprising a longitudinal succession of fence units,

A. each pair of adjacent units forming between them at least first and second vertically-spaced gap portions,

said first gap portions of at least plural fence units being horizontally aligned with one another,

and said second gap portions of at least plural fence units being horizontally aligned with one another,

each fence unit being of substantially rigid one-piece molded plastic construction and having at least one substantially rigid vertically-extending fence member integral with first and second substantially rigid means horizontally-extending from the same end of the unit assymetrically thereof, and

B. at least first and second compliant fibrous strands, each of which extends longitudinally along plural fence units, each strand being embedded within the vertically-extending member and the horizontally-extending means of each fence unit upon the molding thereof and spanning successive units and gap portions to secure said units together and provide said lateral flexibility.

7. A fence according to claim 6 wherein said rigid plastic material is a high impact polystyrene.

8. A fence according to claim 6 wherein said strands are formed of braided nylon.

9. A fence according to claim 6 further comprising

A. a cored-out structure in said vertical fence members, and

B. first and second horizontally-extending portions spanning the cored-out structure of each vertical member and each of which embeds therein one said strand.
