The present invention relates to a tool that can be attached to a power drill and used to tighten wire tree baskets around a tree root ball
Wire tree baskets are used in the field-grown tree industry to facilitate handling and transport of trees from a tree farm to planting sites or to commercial retailers. Such tree baskets wrap around the base, sides and top of the tree root ball and ensure the root system stays intact and viable during loading, shipping and transplanting the tree. Once the tree arrives to its planting site, the wire tree basket can be removed. Alternatively, some planters choose to plant the tree with the wire basket as it provides support to the tree as it establishes its root system into the landscape.
The support provided by a tree basket during planting can reduce the need for staking the tree which adds additional cost to a planting project. Additionally, tree stakes must be timely removed to prevent girdle trunk damage which can result in insufficient nutrient supply to the distal portions of the tree and, if left untended, tree death.
Once a root ball is inserted into a wire tree basket, the wires of the basket must be pulled and tightened around the root ball, a process known as “crimping”. Currently, crimping is done manually using pliers or a T- or J-shaped crimping tool with a distal end that can be placed over a wire. The tool is then rotated by hand to twist the wire to an angle effectively tightening the basket around the root ball.
Manual basket crimping is a time-consuming and labor intensive process that increases the production cost of tree farming. Furthermore, crimping by hand can result in varying degrees of wire tightness throughout the basket, some wires can be overtightened while some wires can be insufficiently tightened.
A wire basket crimping tool that can be attached to a handheld power drill would be more efficient than manual basket crimping methods. Furthermore, such a tool would result in consistent tightening of a wire basket around a root ball for uniform structural support to the root ball and tree during transport and/or planting.
Shortcomings of existing crimping tools are overcome by a wire crimping tool comprising:
In some embodiments, the base of the top portion is circular in cross-section and includes a bottom opening that is oppositely disposed to the distal end of the base.
In some embodiments, the tool shaft portion can include a tapered first end and a second end. In at least some embodiments, the tapered first end can be configured to be inserted into the bottom opening of the base.
In some embodiments, the second end of the tool shaft portion can have a circular outer surface with an opening formed therein, the opening being square in cross-section and configured to attach the wire crimping tool to a square drill attachment.
The wire crimping tool can be rotated clockwise or counter-clockwise about its longitudinal axis.
In some embodiments, the distal end of the wire crimping tool can be positioned over a wire and rotated by a power drill to twist and shorten the wire.
In particular embodiments, the wire crimping tool is used to tighten wires of a wire tree basket around a tree root ball.
Turning first to
Crimping tool 10 can include top portion 12 with base 16 and body 14 that terminates with distal end 20 formed therein and defined by wall 18a and wall 18b. In some embodiments, the length between wall 18a and wall 18b can be ¼-inch (0.635 cm). In some or the same embodiments, the depth of distal end 20 can be ½-inch (1.27 cm).
In some embodiments, base 16 and/or body 14 can be circular in cross-section. In at least some embodiments, the diameter of base 16 is greater than the diameter of body 14. In at least some embodiments, base 16 and body 14 can be continuous. In other embodiments, base 16 can be detached from body 14.
Crimping tool 10 can include tool shaft portion 22 with tapered end 30 (shown in
In some embodiments, tool shaft portion 22 can include circular outer surface 32 with opening 34 formed therein that is square or rectangular in cross-section as illustrated in
In some embodiments, drill attachment 24 can be a male drive socket adaptor. In some preferred embodiments, drill attachment 24 can be a ⅜-inch male square drive socket adaptor with ¼-inch drive shaft 26. In some embodiments, the male drive socket adaptor is hexagonal or rectangular.
Other embodiments of the tool shaft portion of the crimping tool can be configured to accommodate drill attachments with non-square cross-sections such as, but not limited to, hexagonal or rectangular.
In some embodiments, the diameter of base 16 is greater than the diameter of tool shaft portion 22.
In some embodiments, tool shaft portion 22 functions to attach top portion 12 to a handheld power drill (partial views of the distal end of power drill 60 are shown in
In some or the same embodiments, height F of tool shaft portion 22 can be ¾-inch (1.91 cm). In some embodiments, the diameter of tool shaft portion 22 can be ¾-inch (1.91 cm).
In some or the same embodiments, height G of drill attachment 24 can be ¾-inch (1.91 cm) and height H of drill shaft 26 can be 1-inch (2.54 cm).
During use, crimping tool 10 is connected to a drill and can rotate clockwise (or counter-clockwise) about a longitudinal axis.
As shown in
The user then uses power drill 60 to rotate crimping tool 10 and twist, bend or “crimp” the wire such that its length is shortened, illustrated in
Such a method can be used to crimp a wire tree basket around a root ball. The crimping process can be repeated until all necessary wires are crimped, and the root ball secured. As shown in
In some embodiments, the impact driver of the power drill is configured to disengage when an appropriate torque for wire basket crimping is reached such that further rotation of crimping tool 10 is inhibited. This prevents overtightening of the wire basket around the root ball.
In at least some embodiments, the torque of the impact driver can be 205 foot-pounds.
Crimping tool 10 can be used in other applications including, but not limited to, tightening wire fencing.
In some embodiments, crimping tool 10 can be attached to a bench drill press or other non-handheld drill devices.
While particular elements, embodiments and applications of the present invention have been shown and described, it will be understood, that the invention is not limited thereto since modifications can be made by those skilled in the art without departing from the scope of the present disclosure, particularly in light of the foregoing teachings.
