## Abstract

Disclosed herein are industrial goggles. The goggles include a main body having protective glass and formed to correspond to a curvature of a face. A cover is hinged to one side of the front of the main body. A film unwinding roll has a film thereon. An unwinding-roll holding part vertically holds the film unwinding roll on one side of the main body and includes a stationary locking step, a movable locking step, and an elastic spring. A film winding shaft is provided vertically on the other side of the main body to wind the film from the film unwinding roll. A film feeding lever is coupled to the film winding shaft in a gear coupling manner and hinged to the main body. A ratchet means prevents the film feeding lever from rotating in a reverse direction. An elastic support member supports the main body against the face.

## Claims

### Claim 1

A goggle comprising:
a main body having a protective glass coupled thereto;
a cover hinged to one side of of the main body;
a film unwinding roll having a film wound there-around, the film unwinding roll placed vertically at a lateral side of the main body and behind the cover;
a stationary locking step affixed to the main body and having a downwardly extending post portion;
a movable locking step movably coupled to the main body opposite from the stationary locking step, the movable locking step having an upwardly extending post portion, said post portion of the stationary locking step and said post portion of the movable locking step being aligned coaxially to each other and having the film unwinding roll rotatably coupled thereto;
an elastic spring elastically supporting the movable locking step to bias toward the stationary locking step;
a film winding shaft provided vertically on another lateral side of the main body opposite from the film unwinding roll to wind the film from the film unwinding roll;
a film feeding lever coupled to the film winding shaft and hinged to the main body, said film feeding lever having a plurality of gears coupled thereto to rotate the film winding shaft and wind the film on the film winding shaft;
ratchet means coupled to the plurality of gears for preventing the film feeding lever from rotating in a reverse direction; and
an elastic support member coupled to both side ends of the main body to secure the main body onto the worker's face.

### Claim 2 (depends on 1)

The goggle as set forth in claim 1, wherein the film feeding lever comprises a rotating shaft provided adjacent to the film winding shaft, and a handle extending laterally from the rotating shaft, and wherein the plurality of gears comprises a driving gear provided on an end of the rotating shaft, and a driven gear coupled to the film winding shaft and engaging with the driving gear.

### Claim 3 (depends on 2)

The goggle as set forth in claim 2, wherein the rotating shaft is installed in the main body using a torsion coil spring.

### Claim 4 (depends on 1)

The goggle as set forth in claim 1, wherein a face contact member made of a silicone material is coupled to a rear side of the main body, allowing the main body to come in close contact with the face.

### Claim 5 (depends on 4)

The goggle as set forth in claim 4, wherein the face contact member comprises a bendable portion that has continuous ridges and furrows.
