BACKGROUND OF THE INVENTION

The present invention is directed to a handheld trigger-actuated grease applicator. Unlike prior art handheld grease applicators, or grease guns, the present invention allows for improved control, flexibility, and ease of use.

Grease guns of the prior art primarily rely on direct manual depression of a plunger to dispense grease from an attached canister to a target site providing few means to accurately stabilize and maintain control of the grease gun during use. While some prior art grease guns feature trigger-actuation, these triggers similarly apply force directly to the plunger and result in a reduced ability, relative to the present invention, to maximize force applied to the plunger mechanism as access to the plunger is prohibited by the trigger itself.

The present invention improves over the prior art, particularly with respect to the ability to dispense lubricants having higher viscosity, due to its innovative trigger configuration that both takes advantage of a head-unit-mounted fulcrum, which maintains efficient application of manual force to the plunger via trigger actuation, and an exposed plunger that itself may be directly acted upon to apply additional force.
