Abstract
An attachment system and method allows reversely operating a working head with a shaft of different lengths selectively. A first hand tool is reversely connected to an extension shaft to obtain a second, longer-shafted hand tool, both fully operational and sturdy for hand-use, according to applications, work conditions and ergonomics. A range of different lengths hand tools may be contemplated, such as shovels, forks, trowels, transplanters, weed cutters, rakes, hoes, planters, and scoops, for example.
Claims20
A tool, comprising:
- a tool shaft;
- a tool head;
- a sleeve removably connecting the tool head to the tool shaft;
- and
- a clamp connected to the sleeve between an open position and a closed position;
- wherein:
- i) in the closed position, the clamp locks the sleeve about the tool head, thereby connecting and locking the tool head to the tool shaft;
- and
- ii) in the open position, the sleeve is unlocked, thereby unlocking the tool head from the tool shaft.
A combination, comprising:
- a first shaft of a first length;
- a first tool, comprising a second shaft of a second length;
- a sleeve;
- and
- a clamp connected to the sleeve between an open position and a closed position;
- wherein:
- i) in the closed position, the first shaft and the second shaft are aligned, and the clamp locks the sleeve about the first shaft and the second shaft, thereby connecting and locking the first shaft and the second shaft together, and the first tool to the first shaft into a second tool comprising a third shaft;
- and
- ii) in the open position, the sleeve is unlocked thereby unlocking the first tool from the first shaft.
An extension shaft for a tool, comprising a sleeve and a clamp connected to the sleeve between an open position and a closed position, wherein the sleeve comprises an opening, and,
- i) in the open position of the clamp, the sleeve in configured to receive a free end of the tool;
- and
- ii) in the closed position of the clamp, the clamp locks the sleeve about the free end of the tool, thereby connecting and locking the tool to the extension shaft.
