Abstract

Abstract In order to transport a heavy ladder to a work site, a caddy is provided in the form of a pair of transverse pieces having resilient clips installed thereon adapted to engage and clamp onto any rung of the ladder. The pieces are attached at spaced positions to the bridge of a two-wheeled carriage so that the pieces are adapted to straddle and engage a pair of adjacent rungs on the ladder in wheel-barrow position.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 233 words
A caddy for transporting a ladder wheel-barrow style, said ladder having rungs extending between a pair of rails, said ladder comprising: A. a wheeled carriage having a raised bridge member which is at right angles to the direction of movement; B. a pair of transverse pieces having a channel formation mounted at spaced positions of said bridge, said pieces having a length substantially equal to the space between said rails; and C. a pair of clips received within the channels at opposite ends of each piece and secured thereto, said clips extending slightly beyond said ends to provide a forward set of clips and a rear set of clips, the outer faces of said clips being positioned directly adjacent said rails when said clips engage adjacent rungs of the ladder, each clip in at least one set being formed of a resilient plastic block having flat outer faces and being cut to define a pair of spring jaws which are forced apart when applied to a rung of the ladder, the sets being spaced apart to engage adjacent rungs on the ladder, and the distance between corresponding clips on the piece being substantially equal to the distance between the rails on the ladder whereby the outer faces of the clips are positioned directly adjacent said rails, said carriage being formed by a pair of legs whose tops are interconnected by said bridge member.
Claim 2
Dependent Claim 233 words
A caddy for transporting a ladder wheel-barrow style, said ladder having rungs extending between a pair of rails, said ladder comprising: A. a wheeled carriage having a raised bridge member which is at right angles to the direction of movement; B. a pair of transverse pieces having a channel formation mounted at spaced positions of said bridge, said pieces having a length substantially equal to the space between said rails; and C. a pair of clips received within the channels at opposite ends of each piece and secured thereto, said clips extending slightly beyond said ends to provide a forward set of clips and a rear set of clips, the outer faces of said clips being positioned directly adjacent said rails when said clips engage adjacent rungs of the ladder, each clip in at least one set being formed of a resilient plastic block having flat outer faces and being cut to define a pair of spring jaws which are forced apart when applied to a rung of the ladder, the sets being spaced apart to engage adjacent rungs on the ladder, and the distance between corresponding clips on the piece being substantially equal to the distance between the rails on the ladder whereby the outer faces of the clips are positioned directly adjacent said rails, said carriage being formed by a pair of legs whose tops are interconnected by said bridge member.
