The door glass anchor includes a door glass clamp and a pivot structure. The pivot structure includes a tube extension and a pivot rod. One end of the tube extension is attached to the door glass clamp and the pivot rod structure extends from the other end. The windshield glass anchor includes a windshield glass clamp and a pivot extension. The pivot extension includes an outer slide tube, an inner slide tube and a pivoting end. One end of the outer slide tube is attached to the door glass clamp. The inner slide tube is sized to be slidably received by an inner perimeter of the outer slide tube. The pivoting end is formed on one end of the inner slide tube to receive the pivot rod.

## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to installation of windshields in vehicles and more specifically to a single technician large windshield installation tool, which eliminates the need for a second technician to install a windshield on a vehicle.
2. Discussion of the Prior Art
It appears that the prior art does not disclose a tool, which allows a single technician to install a windshield in a vehicle. Two technicians are required to install a large windshield in a vehicle. A first technician lifts one end of the windshield and the second technician lifts the other end of the windshield for installation and both place the windshield on the vehicle. The advantage of a single technician installation is half the labor cost of a two technician installation.
Accordingly, there is a clearly felt need in the art for a single technician large windshield installation tool, which eliminates the need for a second technician to install a large windshield in a vehicle and allows a large windshield to be installed by a single technician in nearly the same amount of time as a two technician installation.
SUMMARY OF THE INVENTION
The present invention provides a single technician large windshield installation tool, which eliminates the need for a second technician to install a windshield on a vehicle. The single technician large windshield installation tool (windshield installation tool) includes a door glass anchor and a windshield glass anchor. The door glass anchor includes a door glass clamp and a pivot structure. The pivot structure preferably includes at least one door retention ear, a tube extension and a pivot rod. One end of the at least one door retention ear is attached to the door glass clamp and the other end is attached to the tube extension at substantially one end thereof. The pivot rod extends from the other end of the tube extension.
The windshield glass anchor includes a windshield glass clamp and a pivot extension. The pivot extension preferably includes at least one windshield retention ear, an outer slide tube, an inner slide tube and a pivoting end. One end of the at least one windshield retention ear is attached to the door glass clamp and the other end is attached to the outer slide tube at substantially one end thereof. The inner slide tube is sized to be slidably received by an inner perimeter of the outer slide tube. The pivoting end is formed on one end of the inner slide tube. A pivoting cavity is formed through the pivoting end to receive the pivot rod.
In use, the door glass anchor is preferably attached to a front driver's side door window, such that the pivoting rod is substantially vertical. The windshield glass anchor is attached to attached to a windshield. The pivoting end is placed over the pivoting rod and supported by the door glass anchor. A single technician then grasps an end of the windshield. The single technician extends the inner slide tube from the outer slide tube and walks around a front of the vehicle, until they are adjacent a front passenger side door window. The technician then lowers the windshield into a vehicle windshield cavity.
Accordingly, it is an object of the present invention to provide a windshield installation tool, which eliminates the need for a second technician to install a windshield in a vehicle.
Finally, it is another object of the present invention to provide a windshield installation tool, which allows a windshield to be installed by a single technician in nearly the same amount of time as a two technician installation.
These and additional objects, advantages, features and benefits of the present invention will become apparent from the following specification.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
With reference now to the drawings, and particularly to FIG. 1, there is shown a perspective view of a windshield installation tool 1. With reference to FIGS. 2–5, the windshield installation tool 1 includes a door glass anchor 10 and a windshield glass anchor 12. The door glass anchor 10 includes a door glass clamp 14 and a pivot structure 16. The door glass clamp 14 is preferably a N-series hand cup, manufactured by Wood's Powr-Grip Co., Inc. of Laurel, Mont., but other glass vacuum clamps may also be used. The pivot structure 16 preferably includes at least one door retention ear 18, a tube extension 20 and a pivot rod 22. One end of the at least one door retention ear 18 is preferably attached to a vacuum support member 24 of the door glass clamp 14 with welding or any other suitable method. The other end of the at least one door retention ear 18 is preferably attached to the tube extension 20 at substantially one end thereof with welding or any other suitable method. The tube extension 20 preferably has a substantial L-shape and is preferably positioned at an acute angle “A” relative to a bottom of a clamping portion 26 of the door glass clamp 14. However, the tube extension 20 may have a different shape, other than the substantial L-shape. The pivot rod 22 extends from the other end of the tube extension 20. A bullet end 28 is preferably formed on an end of the pivot rod 22.
The windshield glass anchor 12 includes a windshield glass clamp 30 and a pivot extension 32. The windshield glass clamp 30 is preferably a N-series hand cup, manufactured by Wood's Powr-Grip Co., Inc. of Laurel, Mont., but other glass vacuum clamps may also be used. The pivot extension 32 preferably includes at least one windshield retention ear 34, an outer slide tube 36, an inner slide tube 38 and a pivoting end 40. One end of the at least one windshield retention ear 34 is preferably attached to a vacuum support member 42 of the windshield glass clamp 30 with welding or any other suitable method. The other end of the at least one windshield retention ear 34 is preferably attached to the pivot extension 32 at substantially one end thereof with welding or any other suitable method.
The inner slide tube 38 is sized to be slidably received by a bushing 44 or the like retained in an inner perimeter of the outer slide tube 36. The pivoting end 40 is formed on one end of the inner slide tube 38. A pivot cavity 46 is formed through the pivoting end 40 to receive the pivot rod 22. The pivoting cavity 46 preferably includes a through hole 48 and an entrance countersink 50 formed on each end of the through hole 48. Each entrance countersink 50 facilitates the insertion of the pivot rod 22 into the through hole 48. One method of pivoting the windshield glass anchor to the door glass anchor has been shown, but other methods may also be used.
In use, the door glass anchor 10 is preferably attached to a front driver's side door window 100, such that the pivoting rod 22 is substantially vertical. The door glass anchor 10 could be modified to be attached to a front passenger's side door window. The door glass anchor 10 is attached by depressing a pump button 13, until the door glass anchor 10 is stationary. The windshield glass anchor 12 is attached to a top of a windshield 102 to be installed in a vehicle windshield cavity 104 of a vehicle 106. The windshield glass anchor 12 is attached by depressing a pump button 31, until the windshield glass anchor 12 is stationary. The pivoting end 40 is placed over the pivoting rod 22 and supported by the door glass anchor 10. A single technician 108 then grasps an end of the windshield 102. The single technician 108 extends the inner slide tube 38 from the outer slide tube 36 and walks around a front of the vehicle 106, until they are adjacent a front passenger side door window (not shown). The technician 108 then lowers the windshield 102 into the vehicle windshield cavity 104.
While particular embodiments of the invention have been shown and described, it will be obvious to those skilled in the art that changes and modifications may be made without departing from the invention in its broader aspects, and therefore, the aim in the appended claims is to cover all such changes and modifications as fall within the true spirit and scope of the invention.
