Abstract
A hand-held oscillating tool has a linear motor and an accessory attachment mechanism configured for releasable coupling to an accessory blade.
Claims26
A hand-held tool comprising:
- a housing defining a motor compartment;
- a head assembly defining a head compartment;
- an air inlet supported by the housing;
- a pneumatic linear motor disposed at least partially within the motor compartment and comprising a piston, the piston comprising a shaft, wherein the piston is configured for reciprocation between a forward position and a rearward position;
- a transmission assembly coupled to the shaft and disposed at least partially within at least one of the motor compartment and the head compartment;
- at least one resilient member disposed at least partially within the head compartment adjacent the transmission assembly and configured for selective contact with one of the transmission assembly and the shaft when the piston is in one of its forward position and rearward position to facilitate dampening of the piston.
3 more elements
A hand-held tool comprising:
- a housing defining a motor compartment;
- a head assembly rotatably coupled with the housing and defining a head compartment;
- a linear motor disposed at least partially within the motor compartment and comprising a piston, the piston comprising a shaft and being configured for reciprocation;
- a transmission assembly coupled to the shaft and disposed at least partially in at least one of the motor compartment and the head compartment;
- wherein each of the transmission assembly, the piston and the head assembly are rotatable together.

A hand-held tool comprising:
- a housing defining a motor compartment;
- a head assembly defining a head compartment;
- an air inlet supported by the housing;
- a pneumatic linear motor disposed at least partially within the air motor compartment and comprising a piston, the piston comprising a shaft, wherein the piston is configured for reciprocation along a longitudinal axis;
- a transmission assembly disposed at least partially in at least one of the motor compartment and the head compartment, the transmission assembly comprising a cam that defines a slot, wherein a centerline bisects the slot and the slot is angled with respect to the longitudinal axis such that the centerline and the longitudinal axis form an acute angle.

A hand-held tool comprising:
- a housing defining a motor compartment;
- an air inlet supported by the housing;
- a pneumatic linear motor disposed at least partially within the air motor compartment and comprising a piston, the piston comprising a shaft, wherein the piston is configured for reciprocation along a longitudinal axis;
- and
- a transmission assembly disposed at least partially in one of the motor compartment and the head compartment, the transmission assembly comprising:
- a boss coupled to the shaft of the piston;
- and
- a cam pivotally coupled with the boss and configured to interact with a support a bearing of an accessory attachment mechanism to facilitate pivoting of the accessory attachment mechanism about a pivotal axis.
