Abstract
Described is a multi-handled tool that is ergonomically designed to maximize the efficiency of the tool by the use of a handle, optionally rotating, affixed to the shaft of the tool. The rotating handle may be rotated and locked into any desired position so the user can adjust the tool to create maximum efficiency. In addition, a footstep is optionally provided above the tool that allows for a greater digging force. A combination of the first, top handle with the ergonomically spaced handle placement that is completely adjustable combined with the footstep above the head of the tool provides for a tool that is much more efficient than the standard tools used today.

(20) Specific Details
(21) As shown in
(22) The second handle 112 is a mid-positioned handle that is formed or attached at any desirable location along the shaft 110. Although the term mid is used, the second handle 112 is not necessarily at a middle point in the shaft 110 and, instead, can be formed or attached at any desirable location or position along the shaft 110. As a non-limiting example, the second handle 112 can be formed (or attached) such that it is in line with the shaft and intersects a long-axis 114 that runs through the shaft 110. The shaft 106 can include multiple components (e.g., first shaft part 101 and second shaft part 103), with the second handle 112 separating those components.
(23) As an alternative non-limiting example and as depicted in
(24) Alternatively, the second handle 112 can be formed such that it is offset from the long axis 114.
(25) Referring again to
(26) In another aspect, the second handle 112 can be rotatable and operate as a rotating handle. In either aspect, the second handle 112 can be used in conjunction with the first handle 107. The first handle 107 includes a grip portion 120 located at user end of the tool. Moreover, the grip portion 120 includes a grip axis 122, with the grip portion 120 formed such that it is positioned at any suitable angle with respect to the long axis 114 and the handle axis 118. As a non-limiting example, the grip portion 120 is formed such that the grip axis 122 is positioned perpendicular to the long axis 114, yet parallel to the handle axis 118. Alternatively and as depicted in
(27) The grip portion 120 is formed of any suitable material to provide for stability and comfort of use. As a non-limiting example, the grip portion 120 is formed of a metal frame that is wrapped with a rubber sleeve.
(28) The multi-handled tool 100 maximizes the usage of the tool implement 102 and the efficiency of the user. By implementing a second handle 112 on the shaft 110 of the tool 100, the user is able to use a greater amount of force with the tool implement 102.
(29) As another improvement over the prior art, the tool 100 optionally includes a footstep 124 that allows for a greater down force (e.g., digging force). The footstep 124 is formed at the tool end 104 and can be integrally formed with the tool implement 102 or separately formed with the tool implement 102 attached thereto. Importantly, the footstep 124 is formed such that it intersects the long axis 114 of the shaft 110. When the user uses their foot to exert force, the multi-handled tool 100 becomes much more effective because the foot and leg strength is coupled with the body weight of the user to channel the tool implement 102 to a directed area. The user is able to use the entire force of their foot and leg as they push down on the center of the footstep 124 (which is directly in line with the long axis 114). In a standard shovel, the user may lose force by having to place their foot off-center while digging, often resulting digging an undesirably shaped hole. The present invention alleviates this issue. The user is able to exert force directly on-center of the foot step 124 to utilize an increased force in the directed area.
(30) As noted above, the second handle 112 can be formed such that it is rotatable. In other words and as shown in
(31) In order to allow for rotation of the second handle 112, the tool 100 includes a rotating mechanism that allows for selective rotation and fixation of the second handle 112. It should be noted that although the second handle 112 appears to be affixed with a circular frame (i.e., the rotating mechanism), the invention is not intended to be limited thereto as it can be formed in any desired shape. For example,
(32)
(33) As shown, in this non-limiting aspect, the second handle 112 includes a second handle grip 302 that is affixed with a circular frame 304. The circular frame 304 includes sliding portions 306 that are formed to allow for rotation within a sleeve. For example, the rotating mechanism includes a first member 308 and a second member 310. Each of the first and second members 308 and 310 include a recess 312 that is formed to accommodate the sliding portions 306. In this aspect, the first and second members 308 and 310 act as clamshells that can be attached with one another (via screws or any other technique) with the circular frame 304 positioned there-between. Thus, when the circular frame 304 is positioned between the first and second members 308 and 310, the sliding portions 306 are allowed to rotate (e.g., 360 degrees) within the recess 312, thereby allowing a user to rotate the second handle 112.
(34) As such, in operation, the rotating second handle 112 allows the user to rotate their hand to the most comfortable and efficient position. Thereafter, it may be desired to lock the second handle 112 in the desired position. In one aspect, the rotating mechanism includes a locking mechanism that allows the rotating handle 112 to be locked into place when the mechanism is activated. The locking mechanism may be unlocked and rotated to another angle to conform to the desire of the user.
(35) The locking mechanism is any suitable mechanism or device that allows a user to selectively lock the rotating handle 112 into place. As a non-limiting example, the locking mechanism includes a locking lever 314 that is slidably attached with the circular frame 304 and that extends from the circular frame 304 to engage with at least one of the recesses 312. The locking lever 314 can be spring-loaded such that it is biased toward engaging with the recesses 312. Thus, when at rest, the locking lever 314 is forced toward the recesses 312 to prevent rotation of the circular frame 304. In operation, a user would retract the locking lever 314 from the recess 312 to allow for rotation of the circular frame 304.
(36) As another non-limiting example, at least one of the recesses 312 can include a series of indentations 316 that are formed to accommodate a portion of the locking lever 314. Thus, in this non-limiting example, the locking lever 314 is biased to engage and lock into one of the indentations 316. A user could retract the locking lever 314 to allow for selective rotation of the circular frame 304 and, thereby, rotation of the second handle 112.
(37) Once the rotating handle 112 is placed at the desired angle, the locking lever 314 locks the interior circular frame 304 into place. When the user desires to rotate the rotating handle 112 to a different angle, the locking lever 314 is unlocked (e.g., retracted from the indentation 316) and the circular frame 304 is free to rotate until the user decides to release the locking lever 314 and allow it to engage with another indentation 316. As noted above and repeated herein for clarity, the specific mechanism that allow for rotation of the second handle 112 is provided as a non-limiting example according to the principles of the present invention as the invention is not intended to be limited thereto.
(38) It should be understood that in all aspects, the second handle 112 is attached with the shaft 106 using any suitable mechanism or technique. As a non-limiting example, the second handle 112 can simply be bolted to the shaft 106 directly (as shown in
(39) Referring again to
(40) In summary, the present invention is a tool 100 that provides for a combination of a first handle, an ergonomically spaced second handle 112 that is completely adjustable and customizable, rotatable or stationary, optionally combined with the foot step 124 above the head of the tool end 104 to provide a home, garden, and construction tool that is much more efficient than the current comparable tools on the market today.
