Abstract

A light shield for eye protection in the welding process comprises a holding unit, a base plate, a filter plate and a universal joint. The filter plate, in conjunction with the base plate, is mounted on a universal joint by which the tilt angle thereof with respect to the holding unit can be free adjusted. Since the filter plate is applied closely to the welding target, the area thereof is small, significantly reducing the weight of the light shield. The base plate further includes a lamp for illuminating the welding target, so that welding can be conveniently done in dark places. The holding unit is for retaining a hand of a user, leaving the fingers of the hand for handling other parts.

Claims

1. A light shield for welding, comprising:

a holding unit having an upper holding plate and a lower holding plate each extended from a connecting barrel, said upper holding plate and said lower holding plate each having a strap and a touch fastener for fastening a palm therein;

a universal joint being substantially a spherical body and rotatably secured within said connecting barrel, said universal joint being capable of rotating freely in said connecting barrel;

a base plate connected to said universal joint on a lower side thereof and to said filter plate on an upper side thereof; and

a filter plate made of an optically opaque material for blocking lights produced in a welding process;

whereby said light shield for welding can be attached to a hand without using the fingers of said hand, and whereby said filter plate can be adjusted about said universal joint to have a wide range of vertical and horizontal tilt angles with respect to said holding unit.

2. The light shield for welding of claim 1 wherein said connecting barrel of said holding unit further comprises a screw hole and a retaining screw for restricting said universal joint in said connecting barrel and therefore for fixing said tilt angles of said filter plate.

3. The light shield for welding of claim 1 wherein said universal joint further includes a screw rod, and said base plate further includes a screw base;

said screw rod is secured in said screw base, thereby connecting said universal joint with said base plate.

4. The light shield for welding of claim 1 wherein said base plate further includes a plurality of screw pins, and said filter plate further includes a plurality of corresponding through holes, thereby said screw pins going through said through holes and further being secured by a plurality of screw nuts, and whereby said filter plate is replaceable.

5. The light shield for welding of claim 1 wherein said base plate further includes a lamp and a power supply unit having at least one battery and a switch for illuminating an object being welded.
