The present invention is directed to tree protection systems.
There are numerous challenges associated with protecting trees, such as saplings from damage to at least the tree trunks by animals, such as rodents, woodpeckers and sapsucking birds, and deer. Tree trunks may also need to be protected from application of herbicides. Additionally, especially during spring, trees may be damaged by “frost cracking,” in which a frozen tree trunk may split when exposed to direct sunlight on one side as a result of uneven heating on opposite sides of the tree trunk. It is also desirable to protect the trees, such as during handling, which may involve transporting, such as associated with harvesting the trees from a tree nursery.
There is a need for a tree protection system that is inexpensive and easily installed/removed.
In an embodiment, a tree protection system including a flexible UV-stable layer including a plurality of openings between about 5 mm and about 9 mm formed therein, the layer configured to protectively surround at least a base of a tree. The tree protection system further including a unitary fastener adapted to secure overlapping opposed portions of the layer together during protectively surrounding the at least a base of a tree in response to application of a single force directed toward the opposed portions.
In another embodiment, the tree protection system includes a flexible UV-stable first layer including a plurality of openings between about 5 mm and about 9 mm formed therein. The tree protection system further includes a flexible UV-stable second layer overlying and secured to the first layer, the second layer impervious to at least glyphosate-based herbicides, the first layer and the second layer configured to protectively surround at least a base of a tree. The tree protection system further includes a unitary fastener adapted to secure overlapping opposed portions of the first layer together during protectively surrounding the at least a base of a tree in response to application of a single force directed toward the opposed portions.
In yet another embodiment, a tree protection system includes a flexible UV-stable first layer including a plurality of openings between about 5 mm and about 9 mm formed therein. The tree protection system further includes a flexible UV-stable second layer overlying and secured to the first layer, the second layer impervious to at least glyphosate-based herbicides, the first layer and the second layer configured to protectively surround at least a base of a tree. The tree protection system further includes a flexible UV-stable third layer at least partially overlying and secured to one of the second layer and the first layer, the third layer configured to substantially protect the at least a base from frost cracking. The tree protection system further includes a unitary fastener adapted to secure overlapping opposed portions of the first layer together during protectively surrounding the at least a base of a tree in response to application of a single force directed toward the opposed portions.

Other features and advantages of the present invention will be apparent from the following more detailed description, taken in conjunction with the accompanying drawings which illustrate, by way of example, the principles of the invention.
Wherever possible, the same reference numbers will be used throughout the drawings to represent the same parts.
The tree protection system includes a layer, such as a mesh, such as a sheet of high density polyethylene (HDPE) mesh or other plastics or polymers, which, when positioned around a tree and laterally surrounding the tree trunk, provides protection to the tree from a broad spectrum of threats including rodents, woodpeckers and sapsucking birds, deer, and scraping in the field. Fasteners, such as unitary or one-piece fasteners may be used to secure the layer around and laterally surround the tree, which fasteners can easily be selectively unfastened as needed. The layer is sufficiently soft and smooth and is of sufficient thickness to prevent damage to a harvested tree during shipment. In one embodiment, the tree protection system protects trees during application of herbicides. In one embodiment the tree protection system provides protection from frost cracking. In summary, the tree protection system provides a “Swiss Army Knife” of tree protection options, as it is recognized that not all protection options may be required.
For purposes herein, HDPE may be a blend with low density polyethylene (LDPE). In one embodiment, the layer may be composed of acrylonitrile butadiene styrene (ABS), polypropylene (PP), nylon, or combination thereof.
In one embodiment, as shown in
In one embodiment, height H1 is between about 18 inches (46 cm) and about 48 inches (122 cm), about 24 inches (61 cm) and about 48 inches (122 cm), about 24 inches (61 cm) and about 42 inches (107 cm), about 24 inches (61 cm) and about 36 inches (91 cm), about 24 inches (61 cm) and about 32 inches (81 cm), about 24 inches (61 cm), between about 32 inches (81 cm) and about 48 inches (122 cm), about 32 inches (81 cm) and about 42 inches (107 cm), about 32 inches (81 cm) and about 36 inches (91 cm), about 32 inches (81 cm), between about 36 inches (91 cm) and about 48 inches (122 cm), about 36 inches (91 cm) and about 42 inches (107 cm), about 36 inches (91 cm), between about 42 inches (107 cm), and about 48 inches (122 cm), about 42 inches (107 cm) or any suitable sub-range thereof.
In one embodiment, width W2 is between about 11 inches (28 cm) and about 19 inches (48 cm), about 11 inches (28 cm), between about 15 inches (38 cm) and about 19 inches, about 15 inches (38 cm), (48 cm), about 19 inches (48 cm) or any suitable sub-range thereof. It is to be understood that these dimensions for H1 and W1 are exemplary and in other embodiments, can be greater than or less than those dimensions. Other layer geometric shapes may be used so long as the layer(s), when wrapped around a tree, covers the intended portion of the tree, and fasteners can secure overlapping portions of the layer(s) together.
In one embodiment, layer 10 has a thickness of about 1 mm (0.04 in). In one embodiment, layer 10 has a thickness between about 1 mm (0.04 in) and about 5 mm (0.20 in), about 1 mm (0.04 in) and about 4 mm (0.16 in), about 1 mm (0.04 in) and about 3 mm (0.12 in), about 1 mm (0.04 in) and about 2 mm (0.08 in), about 2 mm (0.08 in), between about 2 mm (0.08 in) and about 5 mm (0.20 in), about 2 mm (0.08 in) and about 4 mm (0.16 in), about 2 mm (0.08 in) and about 3 mm (0.12 in), about 2 mm (0.08 in), between about 3 mm (0.12 in) and about 5 mm (0.20 in), about 3 mm (0.12 in) and about 4 mm (0.16 in), about 3 mm (0.12 in), between about 4 mm (0.16 in) and about 5 mm (0.20 in), about 4 mm (0.16 in) or any suitable sub-range thereof. In one embodiment, layer 10 has a thickness less than 1 mm (0.04 in). In one embodiment, layer 10 has a thickness greater than 5 mm (0.20 in).
The layers 10, 12, 14 are each composed of flexible UV-stable material. For purposes herein, the term “UV-stable,” “UV resistant,” or similar is intended to define a material having the ability to resist ultraviolet (UV) light or sunlight for extended periods of time, such as months or even years and continue to function as intended. The term “flexible” or similar such as in the context of “flexible” layer or mesh or film is intended to mean that the layer or mesh or film is capable of being flexed sufficiently in order to wrap around and protectively surround a tree 18. As shown in
Other products on the market may be stabilized with additives, but actual UV resistance may be more difficult for the customer to confirm without specialized equipment or years of sun exposure. Unlike other products, this material can be shipped unrolled and flat to customers, reducing overall cost.
It is to be understood that the layers may be composed of any suitable UV-stable or UV resistant material, including, but not limited to plastics.
Layer 10 includes novel sizing of holes or openings 24 (
The term “maximum dimension” refers to the largest dimension of a straight line intersecting any two points along the periphery of an opening or hole. The openings or holes may define a circle, a polygon, such as a regular polygon, such as a hexagon or other closed geometry. This range of opening 24 or hole size is sufficiently large to allow sunlight 50 to come into direct contact with tree bark, aiding growth. This range of opening 24 or hole size permits wind circulation to prevent significant temperature and humidity buildup around the tree trunk. This range of opening 24 or hole size mitigates risk of insect infestation and pest nesting in an enclosed space. The openings 24 or holes are sufficiently small to provide protection to tree bark during shipping and to allow a fastener 16, such as a “button” fastener as shown in
By virtue of the generally uniform arrangement of openings 24 in layer 10, the tree trunk does not develop shaped “tan lines” that may form on the tree trunk as a result of using a tree guard, such as a spiral tree guard, which is a helically coiled or wound strip of material that may be applied over a tree trunk.
Layer 10 or mesh includes numerous beneficial physical characteristics. For example, the mesh is sufficiently rigid when installed to maintain its shape when vertically positioned on one end or edge (i.e., stand on its own), yet sufficiently flexible to be curled or overlappingly extend around the tree. Layer 10 is also sufficiently soft and smooth with sufficiently small holes to provide protection to the trunk during shipping without causing damage to the trunk itself. Layer 10 mesh can be produced via extrusion, sheet perforation, or other suitable fabrication methods. Extruded mesh has been found by Applicant to cost less and have greater durability compared to perforated sheeting.
In one embodiment, tree trunk protection system 20 incorporates a novel herbicide spray protection layer 12 or film. When bonded to layer 10, film layer or layer 12 provides trees 18 with protection from local herbicide application applied low to the ground, such as shown in
Thicker plastic layers are more expensive, less flexible, and more difficult to bond to other layers. Thinner material tears easily, especially during heat treatment. UV-resistance is particularly important if film layer material is vinyl-based. The ability to easily apply a herbicide protection layer 12 or film of varying translucencies, thicknesses, and colors in any combination as appropriate is a beneficial feature of the system.
Thicker layer 10 or mesh is beneficial to the heat application of the layer 12 or film in that some rigidity in the layer 10 or mesh is maintained immediately after application bonding. Thinner layers 10 or meshes heat more quickly and thoroughly, increasing the probability of deformation during the manufacturing process. A smooth and flat layer 10 or mesh surface is likewise beneficial in achieving a strong bond with the layer 12 or film.
In one embodiment, the tree protection system 20 incorporates a novel and beneficial frost protection layer 14 or film. As shown in
In an exemplary embodiment, a vertical layer 14 sheet of film is bonded to the layer 10 or mesh as depicted in
The frost protection film may be applied in a process similar to the bonding process for the spray protection film.
The tree trunk protection system 20 is compatible with a beneficial fastener 16 (
Referring to
In one embodiment, small fasteners such as those used in auto manufacturing that are ultimately intended for use with plastic panels are suitable for the novel application of fastening a plastic mesh around a tree 18. The design of fastener 16 shown in
Another beneficial attribute included with the fastener 16 is a prong stem or prong shaft gap 74. The gap 74 between the prongs 70 and the stem or shaft 64 is sufficiently wide such that the prongs 70 may be elastically compressed to less than a predetermined distance from each other, such as to permit insertion inside of openings 24 (
Yet another beneficial attribute included with the button fastener 16 is a differential stem or shaft length 76. In one embodiment, the stem or shaft 64 has a differential stem or shaft length 76 as compared to the length of the prongs 70 sufficient to allow the prongs 70 to completely tear through both the film layers 12, 14, as well as the layer 10 or mesh. With a shorter differential stem or shaft length 76, the prongs 70 can only partially penetrate layers 12, 14 or films, permitting the layers 12, 14 or films to remain wrapped around the prongs 70, compressing the prongs. The compressed prongs 70 may permit the inadvertent removal of the fastener 16, since the prongs 70 cannot achieve a secure lock. An elongated stem or shaft 64 having a sufficient differential stem or shaft length 76 allows the prongs 70 to extend through the film layers 12, 14, ensuring that the layer 10 or mesh is fastened securely with minimal effort by the user.

Returning to
In one embodiment, the button fastener or fastener 16, as previously discussed, is composed of black PA6 Nylon to ensure UV stability and structural integrity when used outdoors.
