Abstract

A drill attachment for engagement and actuation of a drill apparatus having a bifurcated frame defining a first shaft and a second shaft operatively engaged to the drill apparatus at first and second engagement points is disclosed. A handle is pivotally engaged to the first shaft and is operatively coupled to a trigger actuator located along the first shaft through a trigger cable operatively engaged to a trigger actuator the distal end of the first shat that permits remote actuation of the drill apparatus. The trigger actuator includes a pivotable rocking arm having an actuator pad in selective engagement with the drill trigger such that actuation of the handle by the user pivots the rocking arm in a manner that causes the actuator pad to engage or disengage the drill trigger when operating the drill apparatus. The drill attachment is operatively engaged to the drill apparatus through an adapter component having a proximal portion engaged to the drill attachment and a distal portion defining a generally curved configuration adapted to engage the handle of any conventional drill apparatus.

Dependent claims

A drill attachment configured to be coupled to a drill apparatus, the drill apparatus having a drill handle with a trigger for actuating the drill apparatus, the drill attachment comprising:

a bifurcated frame defining a first shaft and a second shaft, the first shaft defining a proximal shaft portion and distal shaft portion with a base plate defined along a terminal end of the distal shaft portion,
a handle pivotally engaged to the proximal shaft portion of the first shaft, the handle being operatively engaged with a trigger cable;
an adapter component engaged to the distal shaft portion of the first shaft, the adapter component comprising:
an upper clamp member defining an attachment member;
and
a lower clamp member coupled to the upper clamp member, the upper clamp member and the lower clamp member collectively defining a channel, the upper clamp member and the lower clamp member being engaged to the handle of the drill apparatus such that the handle of the drill apparatus is disposed within the channel formed by the adapter component,
wherein the attachment member is secured to the base plate of the first shaft;
and
a trigger actuator coupled to the trigger cable at the distal shaft portion of the first shaft, the trigger actuator having a rocking arm that pivots on the first shaft and is coupled to the trigger cable, and a lateral knee pad arm engaged to said first shaft such that the first shaft of the bifurcated frame is perpendicular to a longitudinal axis of the drill apparatus engaged to the drill attachment and the lateral knee pad arm is parallel to the longitudinal axis of the drill apparatus.

A method of making a drill apparatus comprising:

providing a drill apparatus having a drill trigger and a body defining a proximal portion and a distal portion, the distal portion defining an engagement point and the proximal portion defining a handle;
providing a drill attachment having a bifurcated frame defining a first shaft and a second shaft, the first shaft defining a proximal shaft portion and distal shaft portion, a handle pivotally engaged to the proximal shaft portion of the first shaft, the handle being coupled to a trigger cable, and a trigger actuator coupled to the trigger cable at the distal shaft portion of the first shaft, the trigger actuator having a rocking arm that pivots on the first shaft and is coupled to the trigger cable, wherein the rocking arm includes a retaining arm, wherein the trigger actuator further includes a stationary arm secured to the distal shaft portion of said first shaft, the stationary arm being coupled to the trigger cable, the drill attachment further including a spring including a first end and a second end, the first end coupled to the stationary arm and the second end of the spring being coupled to the retaining arm of the rocking arm, the spring applying a biasing force from the spring to the rocking arm;
and
providing an adaptor component including an upper clamp member and a lower clamp member, the upper clamp member including an attachment member;
and
coupling the adaptor component with the drill attachment and the drill apparatus, including:
securing the attachment member of the adaptor component to the distal shaft portion of the first shaft of the bifurcated frame of the drill attachment, and
engaging one portion of the upper clamp member to the handle of the drill apparatus.
