Appl. No.:

10/040676

Inventors:

Michael Jeffrey Curl - Monroe WI 53566

International Classification:

B32B 3500

US Classification:

425 12, 425 13, 249103, 156 94, 264 3621

Abstract:

An assembly held down with suction cups repairs damage to an automobile windshield and the like. The rod of an extrusion assembly pushes liquefied resin through the interior of a tube and out the end thereof into the damaged area. The tube, jacketed by a vacuum container supplied by a vacuum pump, may be advanced to tightly contact a compression grommet shaped to seal off part of the vacuum created therein. Once that is done, partial withdrawal of the extrusion rod strengthens the vacuum. Certain obstructions, or stops, are situated to prevent damage to the windshield which might otherwise occur if the assembly were advanced too tightly against the windshield.

Abstract:

The invention relates to repair devices for repairing impact resistant glass such as windshields and vertical glass. The repair device can be used to repair many types of damage to glass including cracks, bulls-eye breaks, star breaks, and angle wing breaks. For repairing breaks, the repair device removes air from the break before the resin is applied to the air-evacuated break. For repairing cracks, the repair device pushes resin into the crack while the device is slid along the crack. The repair device has a piston assembly including a piston, a piston casing, and a piston casing receiver; a mounting bracket; and a suction unit, including a manual vacuum pump. A resin is loaded into the piston assembly and delivered to the break or crack by hydraulic pressure, pneumatic pressure, and/or vacuum mode.
