DETAILED DESCRIPTION

[0040] With reference to FIGS. 1-23, the present invention provides a farming tool system generally designated by the numeral 10. In the drawings, not all reference numbers are included in each drawing for the sake of clarity. It will be understood that the above drawings are CAD drawings drawn to scale.

[0041] Referring further to FIGS. 1-23, the farming tool system 10 may include a handle shaft 12 configured to be grasped by a human user that may have a shaft rear end 14, a shaft forward end 16, a shaft length 18 extending from the rear end 14 to the forward end 16, and a shaft width 20 generally perpendicular to the shaft length 18. In some embodiments, the handle shaft 12 is straight. In a preferred embodiment, the handle shaft 12 is cylindrical. In some embodiments, as described in later detail below, the farming tool system 10 includes two handle shafts 12A and 12C as shown in the wheel hoe of FIGS. 19-23.

[0042] The farming tool system 10 may further include a handle locking port 22 that may be located forwardly relative to the shaft forward end 16.

[0043] In the embodiments of FIGS. 1-14 and 19-23, a multi-head attachment 34 is detachably connected to the handle locking port 22 and the multi-head attachment 34 in turn may be connected to multiple farming tools 82A, 82B, and 82C. In the embodiments of FIGS. 15-18, a single farming tool 82 is detachably connected to the handle locking port 22. Preferably, the handle locking port 22 and handle shaft 12 do not change between the embodiments, which allow the handle locking port 22 to accommodate a variety of attachments, including the multi-head attachment 34 of FIGS. 1-14 and the single farming tools 82 of FIGS. 15-18. In addition, as shown in the illustrations, preferably the left, main and right head locking ports 122A, B, and C (which, as described below, are components of the multi-head attachment 34 ) use the same components as the handle locking port 22, which allows the farming tools 88 and 88A-C of FIGS. 1-23 to be detachably connected to either the handle locking port 22 or the left, main and right head locking ports 122A, B, and C to create a system 10 of interchangeable parts.

[0044] Referring further to the handle locking port 22, the handle locking port 22 of FIGS. 1-23 may include a handle locking port open forward end 24 leading to a handle locking port socket (not visible in FIGS. 1-23 but preferably equivalent in structure and design to head locking port socket 126C in FIG. 9, as described later herein), a handle locking port rear end 28, a handle locking port length 30 extending from the handle locking port open forward end 24 to the handle locking port rear end 28 and generally parallel to the shaft length 18, and a handle locking port protrusion (not visible in FIGS. 1-23 but preferably equivalent in structure and design to head locking port protrusion 132C in FIGS. 9 and 11, as described later herein) located between the handle locking port open forward end 24 and the handle locking port rear end 28 and configured to project into the handle locking port socket 26. The handle locking port socket and the handle locking port protrusion are not visible in FIG. 2 because they are inside the handle rod flange 114. However, as mentioned above, the head locking port socket 126C, which preferably utilizes the same design as the handle locking port is shown in FIG. 9 and described later herein. Similarly, the head locking port protrusion 132C, which preferably utilizes the same design as the handle locking port protrusion, is shown in FIGS. 9 and 11 and described later herein. In some embodiments, the shaft length 18 may be, for example, at least about 24 inches, e.g., about 48 inches to about 72 inches. The shaft width 20 may be, for example, between about 1 to about 2 inches. Preferably, the shaft length 18 is between about 20 times and about 80 times the shaft width 20. In other words, the shaft width 20 is preferably small enough to be held in a user's hand. In an exemplary embodiment, the handle shaft 12 is comprised of wood. However, the handle shaft 12 may be comprised of any suitable material.

[0045] As mentioned, the handle locking port 22 may detachably connect to a multi-head attachment 34. As shown in FIGS. 1-14 and 19-23, the multi-head attachment 34 may include a multi-head attachment rear end 36, a multi-head attachment forward end 38, a multi-head attachment length 40 extending from the multi-head attachment rear end 36 to the multi-head attachment forward end 38 and generally parallel to the shaft length 18, a multi-head attachment left end 42, a multi-head attachment right end 44, and a multi-head attachment width 46 extending from the multi-head attachment left end 42 to the multi-head attachment right end 44 and generally perpendicular to the multi-head attachment length 40. The multi-head attachment 34 may further include a multi-head locking bit 48 comprising a multi-head locking bit rear end 50 located adjacent to (i.e., at or near) the multi-head attachment rear end 36, a multi-head locking bit forward end 52, a multi-head locking bit length 54 extending from the multi-head locking bit rear end 50 to the multi-head locking bit forward end 52, a multi-head locking bit width 56 generally perpendicular to the multi-head locking bit length 54, a multi-head locking bit rear notch/indentation 56 located between the multi-head locking bit forward end 52 and the multi-head locking bit rear end 50. Due to the multi-head locking bit rear notch 56, the multi-head locking bit width 56 may be variable along the multi-head locking bit length 54. The multi-head locking bit rear notch 56 may extend around the perimeter of the multi-head locking bit 48, as shown in FIGS. 3-5 for example. The multi-head locking bit 48 may be configured to removably seat inside the handle locking port socket, and the handle locking port protrusion may be configured to releasably engage the multi-head locking bit rear notch 56.

[0046] The multi-head attachment 34 may further include a main head 59B comprising a main base 60B comprising a main base rear end 62B connected to the multi-head locking bit forward end 52, a main base forward end 64B, a main base length 66B extending from the main base rear end 62B to the main base forward end 64B and generally parallel to the multi-head attachment length 40, and a main base width 68B generally perpendicular to the main base length 66B. The word main is used herein for ease of reference to refer to the base 66B connected to the multi-head locking bit forward end 52 (and the components connected to the main base 66B) and is not meant to refer to the importance or size of any component. It will be appreciated that the main base 60B and components are typically between the left and right base 60A and 60C components, as illustrated in FIGS. 1-14 and 19-23.

[0047] The multi-head attachment 34 may further include a rail 70 connected to the main base 60B and comprising a rail left end 72, a rail right end 74, and a rail width 76 extending from the rail left end 72 to the rail right end 74 and generally parallel to the main base width 68B. In the illustrated embodiment, the rail 70 extends through a slot 78B in the main base 60B and the main base 60B is not slideable along the rail width 76. In other words, the main base 60B is fixed.

[0048] The multi-head attachment 34 may further include at least one lateral head 59A and 59C comprising a lateral base 60A, 60C located laterally to the main base 60B and slideable along at least a portion of the rail width 76. For example, in the illustrations, the multi-head attachment 34 includes a left head 59A comprising a left base 60A located to the left of the main base 60B and right head 59C comprising a right base 60C located to the right of the main base 60B. Thus, the at least one lateral head in the illustrations refers to the right head 59C and left head and 59A. In the illustrations, the left base 60A is to the left of the main base 60B when viewed by a user holding the handle shaft 12 and the right base 60C is to the right of the main base 60B when viewed by a user holding the handle shaft 12. However, the words left and right used herein are not meant to be construed as requiring the user to view the components from a certain viewpoint. For ease of reference, the letter A is used in conjunction with the left head 59A and components associated with the left head 59A, the letter B is used in conjunction with the main head 59B and components associated with the main head 59B, and the letter C is used in conjunction with the right head 59C and components associated with the right head 59C. For some components, the components of the right head 59C are specifically labelled and shown in FIGS. 6-14 for exemplary purposes and it will be understood that the components of the left head 59A and main head 59B may be similar in design.

[0049] The left and right bases 60A and 60C (i.e., the lateral bases), respectively, may each include a base rear end 62A, 62C, a base forward end 64A, 64C, a base length 66A, 66C extending from the base forward end 64A, 64C to the base rear end 62A, 62C and generally parallel to the main base length 66B, a base width 68A, 68C generally perpendicular to the base length 66A, 66C, a base slot 78A, 78C extending through the base width 68A, 68C and receiving a portion of the rail 70, and a base lock 80A, 80C. The base locks 80A, 80C may have a locked position in which the left and right base 60A, 60C are not slideable along at least a portion of the rail width 76 and an unlocked position in which the left and right base 60A, 60C are not slideable along at least a portion of the rail width 76. Preferably, the left and right bases 60A, 60C are fully removable from the rail 70. See FIG. 5, where the right base 60A is fully removable from the rail 70.

[0050] Preferably, the handle locking port 22 has an unlocked position in which the multi-head locking bit 48 is removable forwardly out of the handle locking port socket and a locked position in which the handle locking port protrusion moves laterally towards the multi-head locking bit rear notch 58 and prevents the multi-head locking bit 48 from being moved out of the handle locking port socket. Preferably, in the unlocked position a user is able to insert the multi-head locking bit 48 into the handle locking port socket, but in the locked position the handle locking port protrusion prevents the user from inserting the multi-head locking bit 48 into the handle locking port socket.

[0051] The multi-head attachment 34 preferably includes multiple farming tools 82A, 82B, and 82C, which may or may not be detachably connected to the multi-head attachment 34. For example, at least one of the left, right and main head 59A, 59B, and 59C may be detachably connected to a farming tool 82A, 82B, and 82C that has a rear section comprising a rod (which may be in the form of a tool locking bit 134A, 134B, 134C) detachably connected to the left, right or main head 59A, 59B, and 59C and a forward section located forwardly relative to the rear section comprising a metallic projection 88A, 88B, and 88C configured to move dirt or vegetation. Exemplary farming tools 82, 82A, 82B, and 82C are shown in FIGS. 1-15, which depict a triangular wire hoe; FIG. 16, which depicts a wire hoe with a 1 inch offset, FIGS. 17A and 17B, which depict a torsion hoe that also utilizes a wire, and FIG. 18, which depicts a colinear hoe.

[0052] Optionally, the farming tool 82A, 82B, 82C further comprises a tool collar 84A, 84B, and 84C connecting the rod (which may be in the form of a tool locking bit 134A, 134B, 134C) to the projection 88A, 88B, and 88C, the projection 88A, 88B, and 88C is in the form of a wire, the tool collar 84A, 84B, and 84C comprises a tool collar interior 86A, 86B, and 86C comprising at least one segment of the rod 134A, 134B, 134C and at least one segment of the wire 88A, 88B, and 88C, and at least one segment of the rod 134A, 134B, 134C extends rearwardly from the tool collar 84A, 84B, and 84C and at least one segment of the wire 88A, 88B, and 88C extends forwardly from the tool collar 84A, 84B, and 84C, as best seen in FIGS. 3-14.
