Protector for welding

1. A welding protector comprising:

a face shield configured to protect a face of a welder, wherein the face shield defines an interior volume; and

an auxiliary shield disposed adjacent to one edge of the face shield,

wherein:

the auxiliary shield comprises a plurality of portions which overlap each other in a first mode and move to reduce an overlapping area when switching from the first mode to a second mode; and

in the first mode, the plurality of portions are positioned in the interior volume of the face shield;

a fixing member coupled to the face shield;

wherein, in the first mode, fixing member couples the plurality of portions in the interior volume of the face shield; and

wherein the fixing member is hingedly coupled to the face shield such that, from the second mode to the first mode, the fixing member is configured to rotate to couple the plurality of portions in the interior volume of the face shield.

2. The welding protector of claim 1 , wherein the plurality of portions of the auxiliary shield are positioned on an inner surface of the face shield in the first mode.

3. The welding protector of claim 1 , wherein the plurality of portions comprise a first portion and a second portion adjacent to each other, wherein the second portion linearly moves to reduce an overlapping area with the first portion when switching from the first mode to the second mode.

4. The welding protector of claim 1 , wherein the plurality of portions comprise a first portion and a second portion adjacent to each other, wherein the second portion rotates around an axis when switching from the first mode to the second mode.

5. The welding protector of claim 1 , wherein the plurality of portions comprise a first portion and a second portion adjacent to each other, wherein the first portion and the second portion are integrally coupled to each other, and the first portion and the second portion are foldable along a folding line between the first portion and the second portion.

6. The welding protector of claim 1 , wherein the plurality of portions comprise a first portion and a second portion adjacent to each other, wherein the second portion linearly moves on the first portion when switching from the first mode to the second mode.

7. The welding protector of claim 1 , wherein:

the plurality of portions includes a first end and a second end;

the first end is coupled to the face shield; and

in the first mode, the fixing member covers the second end such that the fixing member retains the plurality of portions in the first mode.

8. The welding protector claim 7 , wherein, in the first mode, the fixing member includes a surface shielding the plurality of portions.

9. A welding protector comprising:

a face shield configured to protect a face of a welder, wherein the face shield defines an interior volume; and

an auxiliary shield configured to cover a portion of a head part of the welder and positioned in the interior volume of the face shield,

wherein the auxiliary shield comprises a hard material, and

the auxiliary shield is movable in a direction away from the face shield to increase a covering area of the auxiliary shield configured to cover the portion of the head part;

a fixing member coupled to the face shield;

wherein, in the first mode, fixing member couples the plurality of portions in the interior volume of the face shield; and

wherein the fixing member is hingedly coupled to the face shield such that, from the second mode to the first mode, the fixing member is configured to rotate to couple the plurality of portions in the interior volume of the face shield.

10. The welding protector of claim 9 , wherein the auxiliary shield comprises a first portion and a second portion adjacent to each other, wherein the second portion is movable to reduce or increase an overlapping area with the first portion.

11. The welding protector of claim 10 , wherein the second portion is linearly movable with respect to the first portion.

12. The welding protector of claim 11 , wherein one of the first portion and the second portion comprises a slide hole that extends in the direction away from the face shield, and the other one comprises a protrusion having a central portion disposed in the slide hole.

13. The welding protector of claim 10 , wherein the second portion is rotatable around an axis with respect to the first portion.

14. The welding protector of claim 13 , wherein the auxiliary shield comprises a pair of coupling portions which are coupled to the face shield, and

the second portion rotates with respect to the first portion around an axis that passes though the pair of coupling portions.

15. The welding protector of claim 10 , wherein the first portion and the second portion linearly move in one direction with respect to the face shield, and after the linear movement, the second portion is rotatable to reduce or increase an overlapping area with the first portion.

16. A welding protector comprising:

a face shield configured to protect a face of a welder, wherein the face shield defines an interior volume; and

an auxiliary shield disposed adjacent to one edge of the face shield,

wherein:

the auxiliary shield comprises a plurality of portions which overlap each other in a first mode and move to reduce an overlapping area when switching from the first mode to a second mode;

in the first mode, the plurality of portions are positioned in the interior volume of the face shield;

a fixing member coupled to the face shield;

wherein, in the first mode, fixing member couples the plurality of portions in the interior volume of the face shield;

wherein:

the fixing member includes a flexible strip; and

the flexible strip wraps around the plurality of portions to couple the plurality of portions in the interior volume of the face shield.

17. The welding protector of claim 16 , wherein:

the face shield includes a securing point on an inner surface of the face shield; and

in the first mode, the flexible strip couples with the securing point to couple the plurality of portions in the interior volume of the face shield.

18. The welding protector of claim 17 , wherein, in the first mode, the flexible strip couples with the securing point through one of a hook and loop fastener material, or a snap button feature.
