Abstract
A mask for covering a person's face while welding. The mask includes a body adapted for covering the person's face, the body having a window with a translucent lens positioned over the window. The lens include at least one translucent slat, each slat having a first end and a second end. The first end of each slat being pivotally supported against the body of the mask and movable from a first position where each slat covers a projected area over the body to a second position where each slat covers a reduced projected area over the body, so that part of the face is exposed when the slats are in the second position.
Claims8
A mask for covering a person's face while welding, the mask comprising:
- a body adapted for covering the person's face, the body having a window and a handle positioned below the window;
- a translucent lens positioned over said window, the lens comprising at least two translucent slats, each slat having a first end and a second end, the first end of each slat having means pivotally supporting the slat against the body of the mask and providing motion of each slat from a first position where each slat covers a projected area over the face to a second position wherein each slat covers a reduced projected area over the face;
- and
- a spring loaded trigger mechanism mounted from said handle, the trigger mechanism serving for simultaneously pivoting slats from the first position to the second position, so that when the mask is placed over the face the person, the slats cover part of the face when the slats are in the first position, and so that part of the face is exposed when the slats are in the second position, and so that the spring loaded trigger mechanism biases the slats to said first position.
A mask for covering a person's face while welding, the mask comprising:
- a body adapted for covering the person's face, the body having a window and a handle positioned next to the window;
- a fixed protective lens and a translucent lens positioned over said window, the translucent lens being spaced from the fixed protective lens and comprising a plurality of translucent slats, each of the slats having a first end and a second end, the first end of each slat being behind the translucent lens and pivotally supported against the body of the mask;
- a spring loaded trigger mechanism for providing motion of each slat from a first position where each slat covers a projected area over the face to a second position wherein the slats cover a reduced projected area over the face;
- and
- a spring loaded trigger mechanism mounted on said handle, the spring loaded trigger mechanism serving to pivot the slats from the first position to the second position, so that when the mask is placed over the face the person covers part of the face when the slats are in the first position, and so that part of the face is exposed when the slats are in the second position.
A method for temporarily protecting a portion of a person's face while welding, the method comprising:
- providing a mask for covering a person's face while welding, the mask comprising:
- a body adapted for covering the person's face, the body having a window and a handle positioned below the window;
- a fixed protective lens positioned across said window, and a translucent lens positioned over said window, behind the fixed protective lens, the translucent lens comprising a plurality of translucent slats, each of the slats having a first end and a second end, the first end of each slat being pivotally supported from said window;
- and
- a spring loaded trigger mechanism for pivoting the slats from the first position to the second position, and biasing the slats towards the first position;
- placing the mask over the face the person to cover at least
- part of the face when with the slats when the slats are in the first position;
- and
- exposing part of the face from behind the slats when the slats are in the second position.
