Abstract
A trigger retention mechanism for a device that includes a depressible trigger and a bushing releasably coupled to a housing by a releasable fastener, such as an E-clip. The retention mechanism can also include O-rings to provide an air-tight seal between the bushing and the housing. To replace the retention mechanism, a user need only release the fastener and pull the bushing outwardly from its position within the housing, rather than replacing the entire handle or trigger assembly.
Claims20
A trigger retention mechanism for a device having a housing and a depressible trigger, comprising:
- a trigger body and a trigger stem extending from the trigger body;
- a bushing having a tube that slidably receives the trigger stem and is adapted to be friction-fit within the housing;
- and
- a fastener adapted to releasably couple to the bushing and substantially prevent axial movement of the bushing relative to the housing.
A tool having a housing and a depressible trigger with a trigger body and a trigger stem extending from the trigger body, comprising:
- a bushing having a tube adapted to slidably receive the trigger stem, the bushing adapted to be friction-fit within the housing;
- and
- a fastener adapted to releasably couple to retain the bushing in the housing and substantially prevent axial movement of the bushing relative to the housing.
A method of replacing a trigger mechanism of a device having a housing, comprising:
- removing a fastener circumferentially coupled around a tube of a bushing that substantially prevents axial movement of the bushing;
- applying a force to a flange extending from the tube to overcome resistance from a friction-fit interaction between the tube and the housing;
- and
- disposing a second bushing in the housing in a friction-fit interface.
