Abstract
ABSTRACT OF THE DISCLOSURE
A Tree Protector consisting of a sheet of material generally frustoconical in shape having an exterior annular projection "C" shaped in cross-section and a radial cut dividing the material into a first portion and a second portion. The exterior annular projection on the first portion is a male segment of a first diameter. The exterior annular projection on the second portion is a female segment of a second and larger diameter than the first diameter.
The male segment on the first portion is telescopically received by the female segment on the second portion to maintain the first portion and the second portion of the sheet of material in overlapping engagement thereby forming a truncated cone capable of surrounding the trunk of a tree.
A clamp is secured to the female segment of the exterior annular projection, such that the clamp maintains the positioning of the male segment within the female segment until a preset tension is reached.

Description
~L36~
The present invention relates to a tree protector.
BACRGROUND_OF T~IE I~VENTION
A variety of tree protectors have been developed to prevent insects, such as caterpillars, from crawling up the tree trunk -to attack the leaves, or fruit of trees. It is preferable that these devices be capable of expansion to accommodate tree growth over a number of seasons. This is commonly accomplished by having a sheet of material which overlaps to form a truncated cone capable of surrounding the trunk of a tree. The problem experienced with these devices is the means used to secure the truncated cone to the tree and yet permit expansion to accommodate tree growth. Some devices use means which are capable of expansion but eventually reach the limits of that expansion and either cause damage to the tree or are destroyed as tree growth continues. Other devices use means that are not convenient to install or adjust.
SUMMARY OF THE INVENTION
What is required is an alternate form of tree protector which is easy to install, expandable to accommodate tree growth and will fall from the tree when the limits of its expansion have been reached without damage being caused to either the tree or the tree protector.
According to the present invention there is provided a Tree Protector consisting of a sheet of material generally frustoconical in shape having an exterior annular projection "C" shaped in cross-section and a radial cut dividing the material into a fir~t portion and a second portion. The exterior annular projection on the first portion is a male segment of a first diameter. The exterior annular projection on the second portion is a female segment of a second and larger diameter than the first diameter. The male segment on the first portion is telescopically received by the female segment on the second portion to maintain the first portion and the second portion of the sheet of ' L~
, ~3~
material in overlapping engagement thereby forming a truncated cone capable of surrounding the trunk of a tree.
A clamp is secured to the female segment of the exterior annular projection, such that the clamp maintains the positioning of the male segment within the female segment until a preset tension is reached.
The described invention maintains the truncated cone on the tree trunk while permitting expansion to occur to accommodate tree growth. When the tree grows to a diameter greater than can be accommodated by the device the male segment becomes withdrawn from the female segment and the device falls from the tree. Installation is quick and simple as will be hereinafter described.
BRIEF DESCRIPTION OF TlE~E DRAW~NGS
These and other features of the invention will become more apparent from the following description in which reference is made to the appended drawings, wherein:
FIaURE 1 is a top plan view of a preferred embodiment of the invention.
FI~URE 2 is a side elevation view of the tree protector illustrated in FIGURE 1.
FIGURE 3 is a perspective view of the tree protector illustrated in FIGURE 1.
FI~URE 4 is a section view taken along section lines 4-4 of FIGURE 1.
DETAILED DESCRIPTION OF TIIE PREFERRED EMBODIMENT
The preferred embodiment will now be described with reference to FIGURES 1 through 4. The preferred embodiment, generally designated by reference numeral 10, is a Tree Protector.
Referring to FIGURE 1, tree protector 10 consists of a sheet o~ polymer plastic material 12 generally frustoconical in shape and having a central aperture 13. Material 12 has `L~
, ... .
~.3~7~
an exterior annular projection 14 which is "C" shaped in cross-section, as is illus~rated in ~FIGURE 4. A radial cut 16 divides material 12 into a first portion 18 and a second portion 20. Exterior annular projection 14 on first portion 18 is a male segment 22 of a first diameter. Exterior annular projection on second portion 20 is a female segment 24 of a second and larger diameter than the first diameter of male segment 22. Sheet of material 12 is manufactured of polymer plastic with a number detachable sections 26. A
thumb grip pro~ection 28 extends from material 12. A clamp 3Q is secured to female segment 24 of exterior annular projection 14.
The use of tree protector 10 will now be described with reference to FIGURES 1 through 4. The diameter of a tree (not shown) is measured, and suf~icient detachable sections 26 are removed from sheet of material 12 to ensure that when sheet of material 12 is overlapped to form a truncated cone the trunk of the tree can be accommodated within central aperture 130 Male segment 22 of exterior annular projection 14 on ~irst portion 18 is then inserted into female segment 24 of exterior annular projection 14 on second p~rtion 20.
As male segment 22 is inserted further into female segment 24 first portion 18 and second portion 20 of sheet of material 12 overlap to form a truncated cone capable of surrounding the trunk of a tree, as is illustrated in FIGURES 2 and 3. A polymer foam seal (not shown) is normall~r placed between the tree and tree protector 10 in order to prevent insects from passing along crevices in the tree bark. When tree protector 10 is in position, pressure is exerted with ones thumb upon thumb grip projection 28 to force male segment 22 into female segment 24 until the foam positioned in central aperture 13 and surrounding the tree is compressed. Clamp 30 is then crimped over female segment 24 of exterior annular projection 14 to maintain male segment 22 within female segment 24 until a preset tension is reached. As the tree grows the pressure exerted ..

-gradually causes male segment 22 to be withdrawn from female segment 24. Eventually male segment 22 will be entirely withdrawn from female segment 24, and as a result tree protector 10 wîll fall from the tree. Tree protector 10 can then be reset on the same or a different tree as described above.
The Applicant has had good results by making the preferred embodiment out of .020 gauge polymer plastic obtained from the recycling of pop bottles. In tests the Applicant found that less material was required to form an effective barrier if the inside of the truncated cone was coated with a vegetable or mineral oil. The mineral oil serves to prevent the caterpillars from cocooning under the cone~ If sufficient cocooning is present under the cone the cocoons form a bridge for caterpillars to cross. This was particularly the case for large trees where all of detachable sections 26 were removed lessening the radius of the material remaining.
It will be apparent to one skilled in the art that modifications may be made to the preferred embodiment without departing from the spirit and scope of the invention. In particular, a depending skirt can be added to sheet of material 12.
The present invention relates to a tree protector.
