Abstract

Abstract An animal guard for tree trunks comprising an annular flexible plate having a central circular opening and a skirt portion completely around the central opening; at least one slot extending through the skirt forming the plate into a separable member having abutting edges; a pair of spaced fastener holes in the skirt radially aligned and positioned adjacent one abutting edge of the slot; an inner and an outer spaced parallel arcuate slot in the skirt radially spaced from one another and positioned so that the fastener holes and the slots cooperate with each other when the plate is positioned in a truncated conical position about a tree trunk; the inner slot and associated fastener hole being a substantial distance closer to the inner periphery of the plate than the outer slot and associated fastener hole is to the outer periphery so as to not provide a gripping surface for an animal attempting to pass the guard.

Claims Analysis

Total Claims: 18
Claim 1
Independent Claim 524 words
An animal guard for tree trunks comprising: (a) an annular flexible plate having a central circular opening therein and a skirt portion completely around said central opening: (b) said skirt portion having at all times a constant width and an inner and outer periphery; (c) said plate having a first flat planar position and a second truncated conical position and having at least one radial slit extending completely through said skirt from said inner to said outer periphery; (d) said radial slit forming said plate into a separable member having first and second radial edges of said slit when in said first flat position for permitting said plate to be positioned about a tree trunk; (e) a pair of spaced fastener holes in said skirt radially aligned and position adjacent said first radial edge of said slit, one of which is the inner and the other of which is the outer fastener hole; (f) a pair of spaced parallel arcuate slots in said skirt and radially spaced from each other one of which is the inner and the other of which is the outer arcuate slot; (g) said arcuate slots being radially positioned so that said inner fastener hole and said inner arcuate slot and said outer fastener hole and said outer arcuate slot cooperate with each other respectively when said plate is in said second truncated conical position; (h) each of said arcuate slots being spaced radially from the axis of said plate a distance substantially equal to the radial distance from the axis of said plate to their respective fastener holes; (i) said arcuate slots being adjacent a second radial edge and extending arcuately in a direction away from said second radial edge through a substantial degree of arc; (j) said inner arcuate slot and said inner fastener hole being a substantial distance closer to the inner periphery of said plate than said outer fastener holes and said outer arcuate slot is to said outer periphery of said plate so as not to provide a gripping surface for an animal attempting to pass said tree guard; (k) whereby when said plate is formed into said second truncated conical position and fastener means are positioned in said holes and through said arcuate aligned slots for positioning about a tree trunk, said plate may be adjusted to trunk size and said fastener means locked to prevent slippage in said slots thereby maintaining a tight fit at all times about said trunk; (l) said plate includes a third arcuate slot extending radially from the axis of said plate along a position uniformly between said inner and said outer fastener holes in an arcuate direction away from said first radial edge and extending in a direction opposite to said inner and outer arcuate slots a distance substantially equal to said substantial degree of arc of said inner and outer arcuate slots, said third acruate slot is positioned intermediate said first and second arcuate slots; and, (m) a fastening notch formed in said second radial edge so as to align and cooperate with said third arcuate slot when said plate is in said second truncated conical position.
Claim 2
Dependent Claim 524 words
An animal guard for tree trunks comprising: (a) an annular flexible plate having a central circular opening therein and a skirt portion completely around said central opening: (b) said skirt portion having at all times a constant width and an inner and outer periphery; (c) said plate having a first flat planar position and a second truncated conical position and having at least one radial slit extending completely through said skirt from said inner to said outer periphery; (d) said radial slit forming said plate into a separable member having first and second radial edges of said slit when in said first flat position for permitting said plate to be positioned about a tree trunk; (e) a pair of spaced fastener holes in said skirt radially aligned and position adjacent said first radial edge of said slit, one of which is the inner and the other of which is the outer fastener hole; (f) a pair of spaced parallel arcuate slots in said skirt and radially spaced from each other one of which is the inner and the other of which is the outer arcuate slot; (g) said arcuate slots being radially positioned so that said inner fastener hole and said inner arcuate slot and said outer fastener hole and said outer arcuate slot cooperate with each other respectively when said plate is in said second truncated conical position; (h) each of said arcuate slots being spaced radially from the axis of said plate a distance substantially equal to the radial distance from the axis of said plate to their respective fastener holes; (i) said arcuate slots being adjacent a second radial edge and extending arcuately in a direction away from said second radial edge through a substantial degree of arc; (j) said inner arcuate slot and said inner fastener hole being a substantial distance closer to the inner periphery of said plate than said outer fastener holes and said outer arcuate slot is to said outer periphery of said plate so as not to provide a gripping surface for an animal attempting to pass said tree guard; (k) whereby when said plate is formed into said second truncated conical position and fastener means are positioned in said holes and through said arcuate aligned slots for positioning about a tree trunk, said plate may be adjusted to trunk size and said fastener means locked to prevent slippage in said slots thereby maintaining a tight fit at all times about said trunk; (l) said plate includes a third arcuate slot extending radially from the axis of said plate along a position uniformly between said inner and said outer fastener holes in an arcuate direction away from said first radial edge and extending in a direction opposite to said inner and outer arcuate slots a distance substantially equal to said substantial degree of arc of said inner and outer arcuate slots, said third acruate slot is positioned intermediate said first and second arcuate slots; and, (m) a fastening notch formed in said second radial edge so as to align and cooperate with said third arcuate slot when said plate is in said second truncated conical position.
Claim 3
Dependent Claim 48 words
