Patent ID: 8430272

Claim:
A trigger mechanism for enabling a user to ergonomically discharge aerosol container contents, the trigger mechanism comprising: a trigger unit, the trigger unit comprising a finger-engaging portion, a trigger-guiding portion, and a member-receiving portion, the finger-engaging portion comprising a finger-engaging surface, the trigger-guiding portion comprising trigger-based stop structure and opposed handle-receiving grooves, the member-receiving portion comprising a planar, apertured upright and a planar, member-guiding upright, the apertured upright comprising a member-receiving aperture and a first basal cavity, the apertured upright extending orthogonally relative to the handle-receiving grooves in an upright plane, the member-receiving aperture comprising an aperture axis for receiving a first end of an L-shaped tension member, the first basal cavity comprising a first cavity axis, the aperture and first cavity axes being orthogonal to the upright plane and parallel to one another, the member-guiding upright extending in a guide plane parallel to the upright plane, the member-guiding upright comprising a second basal cavity, the second basal cavity comprising a second cavity axis, the second cavity axis being parallel to the first cavity axis, the member-guiding and apertured uprights thereby together defining a planar, member-receiving channel, the member-receiving channel for receiving the L-shaped tension member when pivoted into an operable position, the member-guiding upright for preventing axial displacement of the first end of the L-shaped tension member relative to the upright plane for preventing removal thereof from the apertured upright, the finger-engaging surface for ergonomically receiving a user's finger, the handle-receiving grooves for receiving opposed guide flanges of a handle assembly, the trigger-based stop structure for preventing excess forward and rearward movement of the trigger unit.
