FIRE SUPPRESSION VEGETATION REMOVAL SAFETY KIT

Abstract

A fire suppression vegetation clearing kit provides for effective vegetation removal operations associated with fire suppression activities while ensuring user safety in operation with an industrial grade wood-chipper. The kit comprises a spade and a rakehoe. In this kit, each of the tools are composed of a non-metal material. The tools can be made of a unitary composition or a combination of non-metal materials. Each tool excludes open-loop handles, such that users are unable to loop a handle, arm, or anything else through the handle. The kit is also usable with a shovel having a non-open-loop handle. The shovel, spade, and rakehoe allow for vegetation clearing activities associated with fire suppression, but the non-metal material and lack of open-loop handle ensures that if a tool is accidentally caught in the industrial grade wood-chipper, the tool will be safely shredded and the user remains out of harms way.

[0052] The embodiment of FIGS. 7-9 is made of a unitary construction. In further embodiments, the head 162 and shaft 166 may be separate elements and later combined via a shaft connector, similar to embodiments of the rakehoe and spade noted above.

[0053] The head 162 is composed of a non-metal material. Similar to the rakehoe and the spade, the head 162 may be made of plastic or any other suitable non-metal material. The manufacturing can be via three-dimensional printing, injection moldings, or any other suitable technique.

[0054] In another embodiment, the head 162 can be made of metal or other material having metal-like properties including providing structure and rigidity for shoveling operations.

[0055] In varying embodiments, the shaft 166 may also be made of any suitable non-metal material, including for example but not limited to plastic, fiberglass, wood, etc.

[0056] The shaft 166 may includes a handle 170. In one embodiment, the handle 170 can have a curved shape, similar to a handle found on a paddle. FIG. 10 illustrates one embodiment of a handle 170 connected to the shaft 166. This embodiment provides for additional purchase for the user when using the shovel 160, while also excluding any type of opening or other means for a user to pass an appendage through the handle.

[0057] The shovel 160 can include varying dimensions, wherein one embodiment the head 162 includes a deep scoop angling approximately 19 degrees from the shaft 166 to a flat portion at the front of the head 162. The total distance of the shovel 160 from the front edge of the face 162 to the top of the shaft 166 and/or the top of the handle 170 can be within a range of 40 inches to 52 inches, with a preferred embodiment of 46 inches. Moreover, the shaft 110 can have a diameter between 1.25 and 1.6 inches, with a preferred embodiment of 1.56 inches. Herein, the shaft diameter may be greater than the shaft diameters of the rakehoe and spade to accommodate the force application on the shaft during use via weight being scooped and dispensed via the head portion.

[0058] Based on the angle of the scoop, the shovel 160, when resting on a flat portion of the scoop bottom has a total height of approximately 24 inches to the top of the handle 170.

[0059] While not expressly illustrated, in further embodiments, the rakehoe and spade may also include the handle 170 disposed on the distal end of corresponding shafts.

[0060] In another embodiment, the shovel handle 170, similar to the handles for the spade and rakehoe, can be any suitable design provided it does not have a loop or other open area for allowing a user to stick an appendage therethrough.

[0061] Where FIG. 10 illustrates a curved handle, FIG. 11 illustrates another embodiment for a handle including a cap 180 that fits over the shaft 182. In one embodiment, the cap 180 may be composed of a rubberized material. The cap 180 provides for added grip for the user when using the tool for vegetation clearing activities. The cap 180 can be any suitable length, example ranging from 6 inches to 18 inches, providing enough length for suitable purchase by user operating the tool.

[0062] As part of the vegetation clearing activities, FIG. 12 illustrates the kit can further include a carrying case 200 having a handle 202. As illustrated, the case can include the rakehoe 100, spade 140, and shovel 160 therein. One embodiment may include a pull string 204 or any other suitable closure for securing the elements within the case 200.

[0063] Where FIG. 12 is one embodiment, any other suitable carrying or assembly case can be provided, such that the tools of the kit are centrally assembled.

[0064] Herein, the kit provides for vegetation removal associated with fire suppression and usable with industrial grade wood chippers. As used herein, an industrial grade wood chipper is any suitable wood or brush chipper having a medium to large intake feed usable within the field of brush clearance. Solely by of example, an exemplary chipper may be any of the following: AX17 Brush Chipper, AX19 Brush Chipper, BC700XL Brush Chipper, BC900XL Brush Chipper, all available from Vermeer.

[0065] Where prior vegetation removal operations associated with fire suppression activities used metal tools for improved durability, inclusion of any industrial grade wood chipper introduces an unacceptable risk level to users, risk of the users being injured, maimed, or killed by a metal tool catching in the chipper. The kit overcomes the limitations by presenting non-metal versions of the tools and excluding any opening in the handles. Should the tools come into contact with the blades of the chipper, the tools will be destroyed and the user let without injury.
