Abstract
A pneumatic impact device and method provide a high powered striking force against a target object. The device includes a core shell that houses a piston sub-assembly and a sear arm sub-assembly, and that further defines a forward gas chamber and a rearward gas chamber. The rearward gas chamber is loaded with compressed fluid via a handle actuator. A mostly external sear trigger assembly responds to the impact of a striker plate against the target object, thereby releasing a sear arm that then releases a piston, which is then accelerated forward by the compressed fluid charge. The device can be re-set manually via compressed fluid (e.g., air) in one embodiment, or automatically via a spring mechanism in another embodiment.
Claims18
An impact device, comprising:
- a core shell member having a first end and an outer surface;
- a piston sub-assembly housed within the core shell member, and including a piston having a head portion;
- a sear arm sub-assembly housed within the core shell member, with the sear arm sub-assembly including a sear arm having a head portion, wherein the piston head portion and sear arm head portion are capable of being fixedly held together;
- a striker sub-assembly secured at the first end of the core shell member;
- and
- a sear trigger assembly secured to the core shell member.
A method of constructing a hand-held impact device, comprising:
- providing a hollow core shell member having a first end, a second end and an outer surface;
- attaching a front bulkhead sub-assembly to the outer surface of the core shell member at a position near the first end;
- securing a piston sub-assembly inside of the core shell member, wherein the piston sub-assembly includes a piston having a head portion;
- securing a sear arm sub-assembly to a rear bulkhead sub-assembly, with the sear arm sub-assembly including a sear arm having a head portion;
- securing the rear bulkhead sub-assembly to the core shell member, such that the piston head portion and sear arm head portion are capable of being fixedly held together;
- and
- securing a sear trigger assembly to the core shell member.
