ABSTRACT:
This invention relates to an electrical caulking gun utilizing a triggering mechanism that controls both the mechanical and electrical operations of a plunger unit that applies axial pressure against a caulking cartridge. The triggering mechanism sits in a grooved channel in a caulking cartridge receptacle and comprises of a trigger rack with a series of wedges on its top and a gear rack, which lies atop the trigger rack, with a series of reciprocating wedges on its bottom that meshes with the wedges on the trigger rack. The wedges on the trigger rack and gear rack cooperate with each other to push the gear rack upward when the trigger rack is moved rearward. The gear rack has a series of gears on its top such that, when pushed upward, they will engage with a drive gear protruding from the plunger unit. The drive gear drives the plunger unit, and is in turn driven by an electrical motor in the plunger unit. The trigger rack, when pulled rearward to its maximum position, will activate the electrical motor. This triggering mechanism is designed to have the drive gear engage with the gear rack before the electrical motor is activated.
