Abstract
A pneumatic hammer extender arm assembly is provided comprising an elongated extender arm body defining a hammer engaging portion formed at a first end of the body, and a hammerhead engaging portion formed at a second end of the body. A hammerhead is detachably engageable to the hammerhead engaging portion to allow for quick change of the hammerhead without the need for any tools. The hammerhead may alternately be implemented to engage and apply an impact force to a fastener that may be axially offset from the extender arm body.
Claims17
A fastener impact assembly, manually engageable to an extender arm body including a first coupling member which is on a first end thereof and comprises a recess of a prescribed depth, and a second coupling member on a second end thereof opposite the first end and comprising a coupling member protrusion of a prescribed length, the fastener impact assembly being used for applying an impact force to a fastener and comprising:
- a hammer engaging member including a hammer protrusion on a first end thereof which is of a length exceeding the depth of the recess defined by the first coupling member, the hammer engaging member being formed to be releasably engageable to the first coupling member of the extender arm body through the advancement of the hammer protrusion into the recess;
- and
- a hammerhead engaging member adapted to be struck by an impact tool and including a cavity within a first end thereof which is of a prescribed depth less than the length of the coupling member protrusion, the hammerhead engaging member being formed to be releasably engageable to the second coupling member of the extender arm body through the advancement of the coupling member protrusion into the cavity.
A fastener impact assembly, manually engageable to an extender arm body including a first coupling member which is on a first end thereof and comprises a recess of a prescribed depth, and a second coupling member on a second end thereof opposite the first end and comprising a coupling member protrusion of a prescribed length, the fastener impact assembly being used for applying an impact force to a fastener and comprising:
- a hammer engaging member including a hammer protrusion on a first end thereof which is of a length exceeding the depth of the recess defined by the first coupling member, the hammer engaging member being formed to be releasably engageable to the first coupling member of the extender arm body through the advancement of the hammer protrusion into the recess;
- and
- a hammerhead adapted to be struck by an impact tool and including a cavity within a first end thereof which is of a prescribed depth less than the length of the coupling member protrusion, the hammerhead being formed to be releasably engageable to the second coupling member of the extender arm body through the advancement of the coupling member protrusion into the cavity.
