Abstract
A portable fence and a trailer for unloading the fence and reloading the fence are disclosed. The fence includes at least two fence sections connected end to end. Stop means are provided to limit the amount of swing between fence sections at the connected end. Remote ends of the fence sections have components of hinge means which allows unrestricted rotation at the remote ends when such are connected together. The stop means and the hinge components which allows unrestricted rotation allow the fence to take up a self supporting V-shape when placed on the ground. The trailer has two housing portions to allow the trailer to be towed both forwardly and reversely. The trailer has rollers at one end which are driven from the rotatable wheels of the trailer to assist in the loading and unloading of the fence to and from the trailer.
Claims24
A fence unit including at least two generally uniformly planar fence sections swingably connected end to end by connecting means enabling said fence sections to be swung into a position in which they are juxtaposed in substantially parallel planes to allow said fence sections to be folded, one of said fence sections having a rod adjacent the connecting means extending beyond the plane of said sections for limiting the amount of relative swing between said fence sections and to prevent the at least two fence sections from being extended to be parallel to each other whereby when said fence sections are opened to the limit allowed by said rod, said fence sections form between them a V-shape such that the fence unit is self supporting when placed on the ground.
A fence unit including two generally uniformly planar fence sections swingably connected end to end by connecting means, one of said fence sections having a rod adjacent the connecting means extending beyond the plane of said sections for limiting the amount of relative swing between said fence sections, said fence sections having hinge means at remote ends thereof for allowing unrestricted swing between the remote ends of a similar fence unit when connected with said first mentioned fence unit whereby when said fence section are opened to the limit allowed by the rod, said fence sections form between them a V-shape such that the fence unit is self supporting when placed on the ground.
A fence unit comprising:
- at least two generally planar fence sections, each of said fence sections having a frame defined by an inner upright member and a remote upright member joined by an upper and a lower horizontal member, and each of said frames holding a wire mesh screen rigidly attached thereto;
- an upper and a lower hinge swingably connecting said fence sections, wherein each of said hinges comprises a U-shaped member rigidly secured to a first one of said inner upright members of a first one of said fence sections and enclosing a portion of a second one of said inner upright members of an adjacent second one of said fence sections such that said second inner upright member is able to rotate within said U-shaped member to allow said first fence section to swing relative to said second fence section enabling said fence sections to be swung into a position in which they are juxtaposed in substantially parallel planes to allow said fence sections to be folded;
- and
- an end of one of said fence sections having stop means attached to or formed integrally therewith such that when said fence sections are opened, said stop means abut against an end of the other of said fence sections to limit the amount of relative swing between said fence sections whereby when said fence sections are opened to the limit allowed by said stop means, said fence sections form a V-shape such that said fence unit is self-supporting when placed on the ground.
A fence unit comprising:
- at least two generally planar fence sections, each of said fence sections having a frame formed by an inner upright member and a remote upright member joined by an upper and a lower horizontal member;
- hinge means including a first component on an end of one of said fence sections having two vertically spaced apart annular members, each having a downwardly projecting connecting pin, and a second component on an end of an adjacent one of said fence sections having two vertically spaced apart sleeves which receive said connecting pins enabling said fence sections to be swung into a position in which they are juxtaposed in substantially parallel planes to allow said fence sections to be folded;
- a securing pin biased over one of said annular members such that said securing pin may be forced away from said sleeve to allow said first and second components of said hinge means to be joined, and then released to be biased back over said annular member to prevent spurious separation of said components;
- and
- an end of one of said fence sections having stop means for limiting the amount of relative swing between said fence sections and to prevent said fence sections from being brought into the same plane whereby when said fence sections are opened to the limit allowed by said stop means and said fence sections form a V-shape such that the fence unit is self-supporting when placed on the ground.
A fence unit comprising:
- at least two generally planar fence sections, each of said fence sections having a frame formed by an inner upright member and a remote upright member joined by an upper and a lower horizontal member;
- hinge means including a first component on an end of one of said fence sections having two vertically spaced apart annular members, each having a downwardly projecting connecting pin, and a second component on an end of an adjacent one of said fence sections having two vertically spaced apart sleeves which receive said connecting pins enabling said fence sections to be swung into a position in which they are juxtaposed in substantially parallel planes to allow said fence sections to be folded;
- a torsion rod joining said vertically spaced apart annular members;
- and
- one of said fence sections having stop means for limiting the amount of relative swing between said fence sections and to prevent said fence sections from being brought into the same plane whereby when said fence sections are opened to the limit allowed by said stop means said fence sections form a V-shape such that the fence unit is self-supporting when placed on the ground.
A fence unit comprising:
- at least two generally planar fence sections, each of said fence sections having a frame formed by an inner upright member and a remote upright member joined by an upper and a lower horizontal member;
- hinge means including a first component on an end of one of said fence sections having two vertically spaced apart annular members, each having a downwardly projecting connecting pin, and a second component on an end of an adjacent one of said fence sections having two vertically spaced apart sleeves which receive said connecting pins enabling said fence sections to be swung into a position in which they are juxtaposed in substantially parallel planes to allow said fence sections to be folded;
- said annular members surround one of said remote upright members for relative rotation therewith such that when said two component hinge means is joined together, said hinge means allows 360 degrees relative swing between said fence sections due to rotation taking place about two axes, a first axis being an axis through said two vertically spaced connecting pins and a second axis being a longitudinal axis through said one of said remote upright members, and
- one of said fence sections having stop means for limiting the amount of relative swing between said fence sections and to prevent said fence sections from being brought into the same plane whereby when said fence sections are opened to the limit allowed by said stop means said fence sections form a V-shape such that the fence unit is self-supporting when placed on the ground.
