US 12,233,569 B1 · Coping nailer

Abstract

A wheeled conveyance straddles and squeezes a parapet or similar vertical wall from both the inside and outside vertical faces. Side wheels may be adjusted to be closer together or farther apart to accommodate the thickness of the wall being straddled. The conveyance traverses the parapet along the top edge, and at least one fastener driver suspended from the carriage faces one or both of the inside and outside vertical faces at some preferably adjustable distance below the top edge of the parapet. While the conveyance traverses the parapet, an actuator selectively and repeatedly actuates the fastener driver(s). Various sensors and controls are provided that permit the speed, fastener spacing, and travel distance to be adjusted. Position awareness and visual, auditory, and radio communications may optionally be employed.

Dependent claims

A coping nailer, comprising:

a conveyance configured to straddle and traverse a parapet, said conveyance having opposed parapet side wheels configured to traverse said parapet and thereby follow said parapet along opposed parapet vertical side walls;
a supply of plural fasteners;
a fastener driver configured when actuated to drive individual ones of said plural fasteners from said supply into said parapet;
and
an actuator configured to selectively and repeatedly actuate said fastener driver while said conveyance traverses said parapet.

2 more elements

A method of applying fasteners into a parapet, comprising the steps of:

straddling said parapet with
a conveyance having opposed parapet side conveyors configured to traverse said parapet along parapet vertical side walls, and
a fastener tool supported by said conveyance;
pressing in a first direction at least a first one of said opposed parapet side conveyors against an exterior surface of said parapet;
pressing in a second direction opposite to said first direction at least a second one of said opposed parapet side conveyors against an interior surface of said parapet;
applying a drive force sufficient to move said opposed parapet side conveyors relative to said parapet and thereby cause said opposed parapet side conveyors to follow said parapet along opposed parapet vertical side walls and said conveyance to follow said parapet about a building perimeter;
actuating said fastener tool at discrete locations along said parapet;
and
driving individual ones of said fasteners into said parapet at individual ones of said discrete locations.
