Abstract
A power tool attachment is configured to connect to a power tool at a static interface and a dynamic interface. The static interface statically fixes the power tool and power tool attachment together. The dynamic interface provides rotational motion generated by the power tool to the power tool attachment. The rotational motion is provided to a drive of the power tool attachment that converts the rotational motion to an output that operates an appliance output of the power tool attachment.
Claims20
A power tool appliance configured for use with a power tool that outputs rotational motion, the power tool appliance configured to attach to and receive rotational input from the power tool, the power tool appliance comprising:
- a housing;
- a drive at least partially disposed within the housing, the drive configured to dynamically connect to the power tool to receive the rotational input from the power tool;
- an input shaft that extends outward from the housing, the input shaft including a hexagonal exterior contour, the input shaft configured to be received within the power tool and to transmit rotational motion from the power tool to the drive, wherein the input shaft is part of a single piece of metal that also forms a portion of the drive, and wherein the single piece of metal converts, at least in part, rotational motion to reciprocating motion to provide an output of the power tool appliance
- a support connected to the housing, the support configured to interface with the power tool to statically connect the power tool to the housing, the support comprising an arm that extends away from the housing and that connects between the power tool and the housing.
A power tool appliance configured for use with a power tool that outputs rotational motion, the power tool appliance configured to attach to and receive rotational input from the power tool, the power tool appliance comprising:
- a housing;
- a drive at least partially disposed within the housing, the drive including a drive shaft configured to rotate on a drive axis;
- a rotational input shaft projecting rearward relative to a rear side of the housing, the rotational input shaft configured to dynamically connect the drive to the power tool to provide the rotational input from the power tool to the drive, wherein the rotational input shaft is anchored in the housing and is connectable to the power tool to receive the rotational input, the rotational shaft input is monolithic with the drive shaft, and the rotational input shaft includes a keyed exterior;
- and
- a support connected to the housing, the support configured to interface with the power tool to statically connect the power tool to the housing, the support comprising an arm that extends away from the housing and that connects between the power tool and the housing.
