Abstract
Abstract Simple, portable fence units for constructing fences are not new. It is also known to interconnect adjacent fence sections using pins and sockets. An improved version of a fence structure for constructing straight or angled fence sections in corrals or animal feeders includes a section or unit for connection to other similar sections or units including a rectangular frame with couplings on each end thereof. The coupling on one end is a pair of short, parallel tubes or sleeves which are welded together and welded to the end of the frame. The other coupling includes a pair of spaced apart tubes or sleeves for receiving the first coupling therebetween. When the outermost sleeves of the couplings on opposite ends of two adjacent frames are axially aligned and a pin is inserted therethrough, the two frames can be pivoted with respect to each other or define an angled length of fence. When both of the sleeves of one coupling are axially aligned with both pairs of sleeves of the other coupling, and a pin or pins is inserted through both pairs of axially aligned sleeves, the two adjacent units are fixedly interconnected to form a straight length of fence.

Total Claims: 12
Claim 1
Independent Claim
279 words
A fence structure comprising a section for connection to other similar sections to define a length of fence, said section including frame means; and coupling means for interconnecting adjacent sections, said coupling means including a first pair of adjacent, parallel sleeve means on one side of said frame means; a second pair of adjacent parallel sleeve means on a side of said frame means opposite to said one side, said first and second pair of sleeve means lying in different horizontal planes, whereby, when the outermost of first and second sleeve means of a pair of adjacent frame means are axially aligned and pin means is inserted therethrough, the two frame means are pivotally interconnected for forming a gate or angled length of fence, and, when both first sleeve means of one frame means are axially aligned with both second sleeve means of an adjacent frame means, and pin means is inserted through both pairs of axially aligned sleeve means, the two frame means are fixedly interconnected to form a straight length of fence, said first sleeve means including a first pair of parallel interconnected sleeves on one side of each frame means; and said second sleeve means including two pairs of second parallel sleeves on an opposite side of each said frame means, said second pairs of sleeves beig spaced apart by a distance greater than the length of said pair of sleeves for receiving the latter therebetween, whereby adjacent similar sections can be pivotally or fixedly interconnected, and said pin means comprising a substantially inverted U-shaped rod, the arms of which can be inserted simultaneously into said first and second sleeve means for interconnecting adjacent fence sections.
Claim 2
Dependent Claim
279 words
A fence structure comprising a section for connection to other similar sections to define a length of fence, said section including frame means; and coupling means for interconnecting adjacent sections, said coupling means including a first pair of adjacent, parallel sleeve means on one side of said frame means; a second pair of adjacent parallel sleeve means on a side of said frame means opposite to said one side, said first and second pair of sleeve means lying in different horizontal planes, whereby, when the outermost of first and second sleeve means of a pair of adjacent frame means are axially aligned and pin means is inserted therethrough, the two frame means are pivotally interconnected for forming a gate or angled length of fence, and, when both first sleeve means of one frame means are axially aligned with both second sleeve means of an adjacent frame means, and pin means is inserted through both pairs of axially aligned sleeve means, the two frame means are fixedly interconnected to form a straight length of fence, said first sleeve means including a first pair of parallel interconnected sleeves on one side of each frame means; and said second sleeve means including two pairs of second parallel sleeves on an opposite side of each said frame means, said second pairs of sleeves beig spaced apart by a distance greater than the length of said pair of sleeves for receiving the latter therebetween, whereby adjacent similar sections can be pivotally or fixedly interconnected, and said pin means comprising a substantially inverted U-shaped rod, the arms of which can be inserted simultaneously into said first and second sleeve means for interconnecting adjacent fence sections.
Claim 3
Dependent Claim
25 words
A fence structure according to claim 1, wherein said pin means includes handle means perpendicular to the top ends of said arms of the rod.
Claim 4
Dependent Claim
23 words
A fence structure according to claim 2, wherein said handle means is substantially C-shaped and integral with the top ends of said arms.
Claim 5
Dependent Claim
21 words
A fence structure according to claim 1, including foot means on said frame means for supporting the latter above the ground.
Claim 6
Dependent Claim
20 words
A fence structure according to claim 4, wherein said foot means is substantially U-shaped, including outwardly and upwardly flaring arms.
Claim 7
Dependent Claim
44 words
A fence structure according to claim 1, wherein said frame means incudes straight sides and ends defining a rectangular border; crossbar means extending between said sides and vertical bar means extending between selected of said crossbar means to define slots for receiving animal heads.
Claim 8
Dependent Claim
44 words
A fence structure according to claim 1, wherein said frame means includes straight sides and ends defining a rectangular border; crossbar means extending between said sides and inclined bar means extending between selected of said crossbar means to define slots for receiving animal heads.
Claim 9
Dependent Claim
58 words
A fence structure according to claim 1, wherein said frame means includes straight sides and ends defining a rectangular border; crossbar means extending between said sides near the top end of said frame means, and vertical bar means extending between said crossbar means and the bottom end of said frame means to define slots for receiving animal heads.
Claim 10
Dependent Claim
31 words
A fence structure according to claim 6, wherein said vertical bar means incudes vertical bars slidably mounted in selected of said crossbars, permitting removal thereof for widening the head receiving slots.
Claim 11
Dependent Claim
34 words
A fence structure according to claim 9, including hook means on the top ends of said vertical bars for engaging the top end of said frame means for retaining said vertical bars in position.
Claim 12
Dependent Claim
43 words
A fence structure according to claim 1, wherein said frame means includes straight sides and ends defining top and bottom rectangular borders carrying said sleeve means; and vertical bar means extending between said top and bottom borders defining slots for receiving animal heads.
