Abstract:

An ergonomic, multi-purpose, attachable and adjustable, auxiliary handle assembly that provides a single supplementary handle for multiple tools and implements. The handle assembly is comprised of an “L”-shaped cylindrical bar that is combined with an adjustable yet lockable, hinged clamp that can be conveniently positioned along the primary cylindrical shaft of elongated tools and implements. This adjustable placement of this new auxiliary handle provides greater convenience in utilizing the tool to maximize its leverage or lifting capability while reducing the risk of muscular strain and fatigue. The adjustable feature allows operators of different sizes; tall to short, to conveniently place the adjustable handle on their tool or implement, at a position on the elongated shaft, that maximizes their preferred handling of the tool for operation. This auxiliary handle allows the user to maximize the effective use of the tool while reducing arm and back strain or injury. In addition to the ergonomic benefits, this new auxiliary handle provides multiple functional benefits for more effective lifting, pulling and pushing operation of tools and implements. In addition, the auxiliary handle enables operational use of tools and implements, with all the above-mentioned benefits, for both day and night use, given the convenient optional lighting component attached to the “L”-shaped handle that sheds light on the tool or implement head (where the head is the shovel, rake, hoe, broom or other tool end attachment).
