Abstract:
1. A portable orchard ladder support system with a front end, a rear end, a top side and a bottom side for a free standing, forward leaning extension ladder that has slidably separate bottom and top sections that have parallel legs and a plurality of spaced apart rungs extending there between and an uppermost rung comprising: an axle brace assembly comprised of: two transport wheels that are mounted on said axles; two windlass support bars each made from a square tube with a distal end, a proximal end, inside dimensions, outside dimensions, and two side walls with latch pin clearance holes through said side walls at said distal and proximal ends of said windlass support bars and approximately 6 inches below said distal end, where said square tube outside dimensions at said proximal end of said windlass support bars are slipped into said square tube inside dimensions of said top end of said forward leaning tube bases with a first grommet seal to cover a joint between said proximal ends of said windlass support bars and said top ends of said forward leaning tube bases and secured with latch pins snapped into said latch pin clearance holes; two windlass assemblies with a rotating center, each built on a square tube with inside dimensions, a proximal end and sidewalls with latch pin clearance holes through both said side walls located toward said proximal end of said square tube where said square tube inside dimensions of said of said proximal end of said square tube slip over said square tube outside dimensions of said windlass support bar and the joint between said proximal end of said square tube and said distal end of said windlass support bar is protected with a second grommet seal and secured with latch pins snapped into said latch pin clearance holes, where said windlass assemblies have approximately 28 feet of a front cable wound around their rotating centers with a hand crank and a ratcheting lock system; two front extension tubes each made from a square tube with a distal end, a proximal end, inside dimensions, outside dimensions and side walls with latch pin clearance holes through said side walls at said proximal end of said front extension tube, where said square tube outside dimensions of said front extension tube proximal ends are fit into said square tube inside dimensions of said front ends of said horizontal tube base where the joint between said front extension tube and said horizontal tube base are protected by a third grommet seal and secured with latch pins that snap into said latch pin clearance holes and have leveling jacks depending from the bottom of said distal ends of said front extension tubes; two windlass support braces each made from a square tube with inside dimensions, outside dimensions, a front surface, a rear surface, and side walls, where said square tube inside dimensions of said windlass support brace are large enough to fit over said square tube outside dimensions of said front extension tubes and said windlass support bars where said rear surfaces of windlass support braces are open at each of said top and bottom ends with latch pin clearance holes in said side walls that match to said latch pin clearance holes in said side walls of said distal end of said front extension tubes and at intermediate location matching height of latch pin clearance holes in said windlass support bar and are secured in place with said latch pins which are snapped into said latch pin clearance holes; two stabilizer bars each made from a square tube with a front end, a back end, inside dimensions, outside dimensions, and side walls with latch pin clearance holes through said side walls at said front and back ends of said stabilizer bars, where said square tube outside dimensions of said front end of said stabilizer bars fits into said square tube inside dimensions of said rear end of said horizontal tube base where the joint between horizontal tube base and stabilizer bar is protected with a fourth grommet seal and secured with said latch pins that snap into said latch pin clearance holes through said rear end side walls of horizontal tube base and said front end side walls of said stabilizer bars; two ladder support bars each made from a square tube with inside dimensions, outside dimensions, a top end, a bottom end, and side walls with latch pin clearance holes through said side walls at said bottom end where said square tube outside dimensions of said ladder support bars fits into said square tube inside dimensions of said top end of said rearward leaning tube base and the joint between said ladder support bars and said rearward leaning tube base is protected with a sixth grommet seal and secured by latch pins snapped into latch pin clearance holes through said side walls of said ladder support bars and said rearward leaning tube bases; two ladder support braces each made from a square tube with side, front and back surfaces, top and bottom ends, and inside dimensions where said front surface is opened at each end and said back surface is open at said bottom end a sufficient distance as to allow said square tube inside dimensions of said ladder support braces to slide over said square tube outside dimensions of said stabilizer bar at said bottom end of said ladder support brace and over said square tube outside dimensions of ladder support bars at said intermediate latch pin clearance hole location where latch pin clearance holes are provided in said side walls at each end of said ladder support braces where the joint between said ladder support braces and said stabilizer bar are secured by latch pins snapped into latch pin clearance holes in side walls of said stabilizer bars; two rear wheel bars each made from a square tube with a front end, a rear end, inside dimensions, side walls with latch pin clearance holes through said front end side walls where said square tube inside dimensions slips over said square tube outside dimensions of rear end of said stabilizer bar and where the joint between said stabilizer bar and said rear wheel bar is protected with a fifth grommet seal and secured with latch pins snapped into said latch pin clearance holes through said side walls of said stabilizer bars and said rear wheel bars; a bar connector rod that connects said two ladder support bars at said top ends and a mid-leg ladder attachment means that secures said bottom section ladder legs to said bar connector rod; a steel strap cross-bar that is chained to the uppermost rung of the bottom section of said extension ladder; a steel strap that is connected from each side of said steel strap cross-bar and connected to said windlass support bars at the height where said windlass support braces interface with said windlass support bars; a cable to ladder connector that is constructed with two rods formed with hooks at the top ends of said rods where said hooks are of sufficient size as to hook over said uppermost rung of said top section of said ladder from the rear side of said extension ladder where the rods are connected at the bottom with a cross-bar with rings attached at both ends and said front cables from said windlass assemblies are snapped into said rings and said front cables are let out as extension ladder is raised and pulled tight and latched when ladder is at a desired operating height, and rear cables are also snapped into said rings and dropped straight down to tightening turnbuckles and then down to slidable rings attached to said stabilizer bar; and a draw bar is attached to center of said front surface of said upstanding vertical wall of said angle iron bar with step up to towing vehicle height with standard trailer hitch mounted thereon.
