There is the step of bending the strap 17 while its first end is in the strap bender 16.

In the operation of the invention, the Pipe Trade stepladder 100 is a new ladder design based off of the IAA platform. There are new and innovative features that make up the new design. The new design has a plastic top 1 of FIG. 1, with features designed to benefit a plumber, as described in concurrently filed U.S. patent application titled “Pipe Tradesman Ladder Top”, a pipe/tube holder 5 with side shields 10, and a utility hook 11.

The top 1 of FIG. 1 has many new features designed especially for the electrician. The top 1 has screw driver holes two hammer/drill holster and includes the Werner Tool Lasso system. Each of the features has a raised icon next to it for easy identification.

The pipe holder 5 of FIG. 2 is designed to hold various sizes of pipe/tubing 7 up to 2 inches in diameter. FIG. 3 shows the pipe/tubing holder 5 with pipe 7 in use. The hooks are connected by a steel stamping 12 and are mounted to the side rail 4 of the ladder with the mounting brackets 13. The steel stamping 12 connecting the two hooks 14 allows the user to operate both hooks 14 with one hand. This one handed operation allows for safer handling of materials and tools. Attached to the rail 4 are side shields 10. The side shields 10 wrap around the inside and the outside of the rail 4 and protect the rail 4 from being damaged by the pipe/tubing 7 or an errant cut by a hacksaw or PVC saw. As shown in FIG. 2, the pipe 7 can be held by the pipe holder 5 and another pipe 7 can be laid perpendicular to it resting on the front step 3 and the scallop portion 8 of the pipe holder 5. This allows the user a place to create and hold the necessary joints and fittings needed.

The pipe holder 5, as shown in FIG. 2, is designed to hold various sizes of pipe 7 up to one inch in diameter. The hooks 14 are connected by a stamping 12 and are mounted to the side rails 4 of the ladder 100 with the mounting brackets 9. The stamping 12 allows the user to operate both hooks 14 with one hand. This one-handed operation allows for safer handling of materials and tools. To use the pipe holder 5, the user has to pull the hooks 14 toward himself and then place the pipe 7 in the hooks 14. The pipe 7 then rests on the side shields 10. Once the pipe 7 is pulled out of the hooks 14, the hooks 14 will retract.

The pipe holder 5 is further described in FIGS. 6 and 7. The hooks 14 are welded to the stamping 12 which makes them move together. The pivot point 34 attaches the hooks 14 to the rail 4. The user will grab the hook 14 and pull it towards himself. The spring 35 automatically retracts the whole assembly when the user is done.

The pipe holder 5 is limited by the step 3, as shown in FIG. 2. The front of the step 3 will stop the holder when it is coming forward and the rear of step 3 will stop it when it retracts.

The new integrated pipe/tube holder 5 secures the work piece between the pipe/tube holder 5 hooks 14 and the protective rail shield for easy and safer cutting. The holder 5 can also be used to assemble and weld or glue pieces together prior to the final installation.

Mounted on the rear horizontal 6 of FIG. 4 is the utility hook 11. This hook 11 is mounted on the 5^th rear horizontal from the bottom. The hook is designed to hold up to 35 pounds and has a variety of uses.

Users will tape or screw hooks 14 onto the outside of their ladder rail to hold tools and buckets when not in use. These hooks 14 are often mounted on the outside of the rail. They will then hang heavy tool belts and buckets that could tip the ladder over. The integrated utility hook 11 is placed in the inside of the frame on the center of the step 3 of the ladder so not to create a tipping hazard and is firmly secured to the step 3.

The strap bender 16 of FIG. 5 can be located on a horizontal 6 or a rail 4. The strap 17 that is to be bent is slid into the opening 15 on the strap bender 16. The user then bends the strap 17 to a 90 degree angle.

The strap bender 16 is a smaller steel part attached to the ladder. It is used to bend a 1 inch 90 degree end on a thin steel strap 17. These straps 17 are used on the heating and air conditioning ducts.

In an alternative embodiment, the pipe holder is designed to hold various sizes of pipe/tubing 7 up to 3 inches in diameter. FIG. 8 shows the pipe/tubing holder with pipe 7 in use. The hooks 30, 34 are connected by a steel stamping 32. The steel stamping 32 connecting the two hooks 30, 34 allows the user to operate both hooks with one hand. This one handed operation allows for safer handling of materials and tools. Attached to the rail are side shields 33, 36. The side shields 33, 36 wrap around the inside and the outside of the rail and protect the rail from being damaged by the pipe/tubing 7 or an errant cut by a hacksaw or PVC saw. As shown in FIG. 8, the pipe 7 can be held by the front step 3 and the scalloped divot 31 in the steel stamping 32. This allows the user a place to create and hold the necessary joints and fittings needed prior to installation. The hooks 30, 34 rotate on 35 outward creating a “V” for the pipe 7 to rest between the hooks 34, 30 and the rail shields 33, 36, as shown in an open position in FIG. 10. The hooks 34 and 30 may have notches and or round cuts in them to better hold a pipe or bar shape. The hooks are shown in a retracted position in FIG. 9.

Although the invention has been described in detail in the foregoing embodiments for the purpose of illustration, it is to be understood that such detail is solely for that purpose and that variations can be made therein by those skilled in the art without departing from the spirit and scope of the invention except as it may be described by the following claims.
