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.
Claims4
A repair device for breaks and cracks in a glass or plastic substrate comprising:
- a a piston assembly comprising in turn
- i a piston having
- a proximal end and a distal end;
- and
- a seal at the distal end of the piston;
- and
- rotation grips;
- ii a piston casing having
- an inner surface and an outer surface wherein the piston casing threadably receives the piston, thereby forming a resin-holding gap between the distal end of the piston and the inner surface of the piston casing, the gap sealed by the piston seal;
- and
- a seal;
- and
- iii a piston casing receiver having
- an inner surface and outer surface wherein the piston casing receiver threadably receives the piston casing and the outer surface of the piston casing and the inner surface of the piston casing receiver define a clearance having a proximal end and distal end, the proximal end sealed by the piston casing seal;
- a proximal end and distal end having a first opening that is continuous with the clearance;
- an insert connected to the piston casing receiver at the first opening;
- a continuous side wall that has a second opening therein disposed remote from the distal end of the clearance;
- and
- rotation grips;
- the repair device further comprising
- b a mounting bracket removably connected to the piston casing receiver for placement on the substrate and comprising in turn
- i a bracket plate having a threaded aperture for receiving the piston casing receiver;
- ii a suction device for mounting the bracket plate to the substrate;
- iii leveling means;
- and the repair device further comprising
- c a pump unit removably connected to the second opening of the piston casing receiver for creating a vacuum or pressure in the clearance of the piston assembly, comprising in turn
- i a vacuum pump for creating a vacuum in the clearance of the piston assembly for removing gas and liquid from the break;
- ii a fitting for connecting the vacuum unit to the piston casing receiver at the second opening;
- and
- iii a vacuum gauge.
