By maintaining the open or closed state as it is, when used as a face protector or a welding mask, the security projection 220 does not open or close on its own.

7 (a) and 7 (b) show the security sight 220 closed state. At this time, since the parallel key inner peripheral surface 214a and the parallel key engaging surface 225a are in a state where the hinge shafts 225 and 225 'are fitted in the hinge holes 214 and 214', the security projection unit 220 is forcibly enumerated. Unless the closing and closing operation is performed, the parallel key engaging surface 225a is locked to the parallel key inner peripheral surface 214a so that the hinge shafts 225 and 225 'are not spontaneously rotated. Will not open on its own.

Therefore, when the frame 221 is forcibly rotated upward in order to make the security sight 220 open, the hinge shafts 225 and 225 'rotate as shown in FIGS. 8A and 8B. It rotates while contacting the parallel key inner peripheral surface 214a of the balls 214 and 214 '.

At this time, the material of the hinge protrusion wheel parts 215 and 215 'itself is slightly opened or slightly distorted when subjected to a force (external force), and when the external force is lost, the resin has its own elasticity and resilience that can be returned to its original state. Since the hinge shafts 225 and 225 'are forcibly rotated because they are formed of a plastic material, the parallel key inner circumferential surface 214a is pushed slightly to both sides by the hinge shafts 225 and 225', and the upper and lower inner circumferential surfaces thereof. Is distorted slightly inwardly, and the hinge shafts 225 and 225 'are completely rotated so that the parallel keying surfaces 225a of the hinge shafts 225 and 225' are the same as those of (a) and (b) of FIG. In the same state as the parallel key inner peripheral surface 214a, the slightly distorted hinge holes 214 and 214 'are returned to their original state, whereby the parallel key engaging surface 225a is locked to the parallel key inner peripheral surface 214a. Becomes

Therefore, unless the security projection 220 is forcibly rotated downward in the downward direction, the security projection 220 in the open state does not occur at all when it is closed by itself in the downward direction, thereby preventing the security projection. The opened state of 220 can be maintained as it is.

Therefore, the present invention enables the opening and closing operation of opening and closing the security transparent part 220 and also maintains the state where the parallel key engaging surface 225a is caught on the parallel key inner peripheral surface 214a after the opening operation and after the closing operation. By being able to be so that the security projection 220 is not shaken or rotated by itself.

Therefore, the present invention can be used as a face protector in a state in which the security sight 220 is opened as described above, while also operating the security sight 220 in a closed state so that it can also be used as a welding mask. However, when used as a welding mask, when checking the welded parts are welded properly from time to time, by opening the security projection 220, it is easy to check whether the welding was well through the transparent window member 213, thereby welding work Efficiency will be improved.
