Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a whole perspective view of a part of the combined safety mask according to the present invention was removed, Figure 2 shows a partial cross-sectional configuration of the combined state, Figures 3 to 6 are welding safety glasses according to the present invention It shows the mounting structure and security perspective means having the same.

Referring to Figures 1 and 2, the welding safety mask for the combined facial mask of the present invention is largely divided into a head cover portion 10 and the face that is provided with a size that can cover the entire face to the head cover portion 10 lower side It is provided with a mask portion 20 and the tightening wearing means 330 coupled to the rear side of the head cover portion 10.

In addition, the face mask 20 is provided with a transparent see-through section 210, and the security see-through means 200 having a welding safety glasses mounting structure 220 in front of the transparent see-through section 210 in the vertical direction. It is configured to be opened and closed to open and close.

The welding safety eyeglasses mounting structure 220 is to be carried out in the welding safety mask combined with a welding mask of the present invention, or in some cases can also be carried out in a conventional welding mask, the welding security eyeglasses mounting structure 220 will be described as follows. .

3 to 5, the welding security eyewear mounting structure 220 of the present invention includes a locking step portion 223 provided in the horizontal direction at the lower side of the see-through hole 222 drilled in the frame 221.

In addition, the engaging holes 222 are projected on each of the four corners of the inner surface of the see-through hole 222 so that each coupling groove 226 is provided.

Into the coupling groove 226 is inserted into the outer transparent window member 227 and the safety glasses member 228 having a size that can cover the see-through hole 222 so that the bottom end is caught on the locking jaw portion 223 through the see-through 222 is installed to be in close contact with the inner side so that the bottom end 228b of the eyeglass member 228 is installed so that a part of the locking projection 223 slightly protrudes outward.

The outer transparent window member 227 has a thin thickness as a resin material, and when inserted into the coupling groove 226, one outer side of the transparent window member 227 is bent slightly so as to be fitted into the other coupling groove 226.

And the safety glasses member 228 is made of a glass material and has a relatively thick thickness with the outer transparent window member 227, first one side is fitted to the coupling groove 226, the other side is fitted. Therefore, the width of the safety glasses member 228 has a length slightly shorter than the outer transparent window member 227 is used.

Referring to FIG. 5, an inner transparent window member 227 ′ having a length Lb longer than the length La of the safety glasses member 228 is inserted outside the safety glasses member 228 so that the safety glasses member 228 is inserted therein. ) Is fixed to pressurize.

However, at this time, the lower end portion 227'a of the inner transparent window member 227 'is installed to be lowered downward than the lower end 228a of the safety glasses member 228 so that the inner surface of the frame 221 and the inner transparent window member 227 are installed. ') Is provided to have a release tool fitting space portion 229 for separating the inner transparent window member 227' from the locking projection 224 between the lower end (227'a).

The inner transparent window member 227 'is formed of a resin material which can have a bend so that one end is first inserted when the inner transparent window member 227' is fitted to the coupling groove 266, and the other end is bent when the other groove is inclined to the coupling groove 226. Let's go.

And even in a combined state, the inner transparent window member 227 'is maintained to be inserted slightly bent so that it is not visible to the naked eye so that the pressing force is applied to the safety glasses member 228.

Therefore, the eyeglasses member 228 and the outer transparent window member 227 are kept in a fixed state while being in close contact with the see-through hole 222 by the pressing force of the inner transparent window member 227 '.

On the other hand, it is necessary to replace the outer transparent window member 227 because damage is caused to the surface of the outer transparent window member 227 by welding.

In this case, for example, by using a tool such as a screwdriver to insert the end portion into the separation tool fitting space portion 229 and then forcibly lifts the lower end portion 227'a of the inner transparent window member 227 'outwardly. The lower end portion 227'a is lifted up as shown in the phantom line in FIG. 6, and thus is separated from the locking protrusion 224 because both end portions of the inner transparent window member 227 'are moved toward the center.

Of course, if the raised lower end 227'a is lifted enough to be grasped by hand, it can be separated more easily by being pulled out by hand. Since the inner transparent window member 227 'is only about 1.5 mm in thickness, the inner transparent window member 227' is easily heard because of its thin thickness.

Next, when the inner transparent window member 227 'is separated, the pressing force of the inner transparent window member 227' is lost, so that the safety glasses member 228 and the outer transparent window member 227 flow in the coupling groove 226. As you can get out easily.

Then, the damaged outer transparent window member 227 is replaced with a new one, and then the outer transparent window member 227 and the safety glasses member 228 and the inner transparent window member 227 'are joined in the order as described above. Insert into the bracket).

Therefore, the present invention needs to be replaced as the safety glasses member 228 is installed between the inner and outer transparent window members 227'.227 so that the relatively expensive safety glasses member 228 is not damaged. There is no economic advantage.

In addition, in fixing the outer transparent window member 227 and the safety glasses member 228 and the inner transparent window member 227 'can be fixed without a separate fixing means and has the advantage that can be easily replaced.

The welding safety eyewear mounting structure 220 may be implemented in a conventional welding mask, and may also be implemented in a welding safety mask according to the present invention.

Therefore, the welding mask combined safety face mask employing the welded eyeglasses mounting structure 220 is as follows.

1 and 2, the welding safety mask combined with a welding mask of the present invention is used to be fixed to the hard hat (50).

Therefore, the helmet 50 is inserted into the inner head cover 10 is in close contact, the face mask 20 is provided with a size that can cover the entire face under the head cover 10, and the head cover Part 10 has a tightening wearing means 330 to be coupled to the rear end and to be coupled to the hard hat 50 with a tightening force.

In addition, the front face part 200 is provided with a transparent see-through section 210.

The transparent see-through part 210 has a frame 211 protruding integrally with the face mask part 20, and one side of the frame 211 is provided with a transparent window coupling hole 217.

The transparent window coupling hole 217 is inserted into the transparent window member 213 so as to be engaged and fixed to the coupling groove 216 inside the see-through hole 212.

In addition, hinge protrusion wheel parts 215 and 215 'having hinge holes 214 and 214' having parallel key inner circumferential surfaces 214a on both sides of the inner circumferential surface are formed on both sides of the upper portion of the frame 211.

As described above, the frame 211 having the hinge protrusion wheel parts 215 and 215 'is integrally formed by injection molding together with the head cover part 10 and the face mask part 20 as a resin (plastic) material.

And the present invention is provided with a security transparent means 200 which opens and closes the opening and closing operation in the vertical direction from the front transparent part 210.

The security transparent means 200 is such that the outer transparent window member 227 and the safety glasses member 228 and the inner transparent window member 227 'are installed in close contact with each other in the perspective hole 222 of the frame 221. It is configured to have a welding safety glasses mounting structure 220.

Since the welding safety glasses mounting structure 220 has already been described, a description thereof will be omitted and only the remaining components will be described.

Therefore, the security projection means 200 has hinge shafts 225 and 225 'having parallel keying surfaces 225a on both sides of the upper inner surface of both side portions 221a of the frame 221.

The hinge shafts 225 and 225 'are rotated by being fitted into the hinge holes 214 and 214', respectively, so that the security sighting means 200 opens and closes in the upper and lower directions, and the lower side is opened and closed to perform the opening and closing operation as described above. The handle part 221b is provided.

Hinge shafts 225 and 225 'of the frame 221 are coupled to fit into the hinge holes 214 and 214' of the frame 211, respectively, as shown in FIG.

At this time, since the frame 221 is made of resin, the two side pieces 221a are forced to open slightly to the outside so that the hinge shafts 225 and 225 'are fitted to the hinge holes 214 and 214', respectively.

FIG. 8 is an enlarged view of the hinge holes 214 and 214 'and the hinge axes 225 and 225' according to the present invention, and FIG. 9 is the diameter D of the hinge holes 214 and 214 'and the hinge axes 225 and 225'. It is a figure for demonstrating the formation state of the parallel key inner peripheral surface 214a and the parallel key engaging surface 225a formed in both sides by showing as a peripheral surface (circular shape).

Therefore, referring to FIG. 9, the diameters of the circumferential surfaces of the hinge holes 214 and 214 'or the hinge axes 225 and 225' are referred to as "D", and the parallel key inner peripheral surface 214a or the parallel keying surface 225a is provided at the circumferential surface. When the distance to the portion is called "D1" and "D3", and the distance between the two parallel key inner peripheral surfaces 214a or the parallel keying surface 225a is "D2", the ratio of the intervals of D1: D2: D3 is 1: It is preferable that the parallel key inner circumferential surface 214a or the parallel keying surface 225a be formed so that the ratio is 8: 1. Of course, at this time, the hinge holes (214, 2145 ') are manufactured to have a plus (+) tolerance and the hinge shafts (225, 225') are manufactured to have a negative (-) tolerance to the hinge holes (214, 214 ') hinge axes (225, 225'). Each of these is fitted so that it can be rotated.

Therefore, referring to FIG. 2 again, the present invention is used as a welding mask by performing a welding operation in a state in which the security transparent means 200 is covered in front of the transparent transparent portion 210 as shown by the solid line when the welding operation is performed. Will be.

At this time, the welding portion is to be observed through the transparent window member 213 of the transparent see-through part 210 and the inner and outer transparent window members 217 'and 217 of the transparent see-through means 200 and the safety glasses member 228. .

However, when the present invention is used as a safety face mask, the frame 221 is transparent as shown in the phantom line of FIG. It is to have a state in which the upper portion 210 is separated.

On the other hand, in the present invention, a state in which the security transparent means 200 is hidden in front of the transparent transparent portion 210 is referred to as a closed state, and the transparent transparent portion 210 is defined as an open state in which the security transparent means 200 is separated. And, it will be defined and described as the opening and closing operation or the opening and closing operation or opening and closing operation of the security perspective means 200 in the closed and open state.

Therefore, the security projection means 200 is to be able to observe the front portion only through the transparent window member 213 of the transparent see-through portion 210 in the open state at this time can be used as a safety face mask, the present invention is It will be used as a safety face mask or welding mask as a product at this time will be used as a safety face mask or welding mask in the state of the head protection by being worn on the helmet (50).

As described above, the present invention, which can be used as a face protector or a welding mask as a single product, does not forcibly rotate the frame 221 by holding the handle part 221b in the fully open or closed state. By maintaining the open or closed state as it is, when used as a face protector or a welding mask, the security projection means 200 does not open or close on its own.

10 (a), (b) shows the security perspective means 200 is closed. 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 means 200 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 200 open, the hinge shafts 225 and 225 'rotate as shown in FIGS. 11A and 11B. 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 aligned with (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, the security projection means 200 in the open state does not occur at all when the security projection means 200 in the open state is closed by itself in the downward direction unless the security projection means 200 is forcibly rotated downward. The open state of 200 can be maintained as it is.

Therefore, the present invention enables the opening and closing operation of opening and closing the security transparent means 200, 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 doing so, the security clairvoyance means 200 will not be shaken or rotated on its own.

Therefore, the present invention can be used as a face protector while the security sighting means 200 is opened as described above, while being able to operate the security sighting means 200 in a closed state to be used as a welding mask. However, when used as a welding mask to ensure that the welded parts are welded properly from time to time by opening the security projection means 200 to be able to easily check whether the welding was well through the transparent window member 213 and thereby welding work Efficiency will be improved.

Again, referring to FIG. 1, the present invention includes a fastening wearing means 330 to be worn on the helmet 50.

The tightening and wearing means 330 is provided with an adjusting band 331 and the fixing band 332, the adjustment band 331 and the fixing band 332 are band connection portion 11 on both sides of the head cover portion 10, respectively ) Is combined. However, in some cases, the adjustment band 331 and the fixed band 332 may be configured to be integral with the band connecting portion 11, respectively.

Therefore, the adjustment band 331 and the fixing band 332 formed of a resin material is to have a band fixing protrusion 330a forcibly fitted into the coupling hole 12 in the band connecting portion 11.

Since the band fixing wheel part 330a is made of a resin, the band fixing wheel part 330a can be pushed into the coupling hole 12 by force, and the band fixing wheel part 330a is completely supported by its own restoring force. As shown in Fig. 13, the band connection part 11 is connected to the inner surface while being unfolded.

Therefore, as described above, the fastening wearing means 230, which is connected to the control band 331 and the fixed band 332 to be integral with the band connecting portion 11 is configured to adjust the length very conveniently and easily.

14 and 15, the outer surface of the adjustment band 331 of the tightening and wearing means 330 is provided with a plurality of engaging wedge projections 333 having a vertical surface 333a and an inclined surface 333b in the longitudinal direction.

And the rear end of the fixing band 332 is configured to include a freeze frame portion 334 protruding to have an access hole 334a through which the adjustment band 331 passes and both sides have a button hole 334b.

Inside the unlocked frame portion 334 there is an elongated arm 335a integrally formed at the rear of the button 335 exposed by the button hole 334b, and an outer vertical surface 336a and an inner sloping surface at the rear end of the arm 335a. There is a jersey wedge 336 having a 336b, the jersey wedge 336 has a locking wedge 333 that passes under it and the band engaging button portion 337 formed so as to always keep the locked state is embedded Are combined.

Therefore, referring to FIG. 16, the band locking button part 337c is provided with a plurality of fixing hooks 337c that are forcibly fitted into the hook hole 334c provided in the unlocking frame part 334. 337 is fixedly coupled to the unlocking frame portion 334, the stopper 335b of the button 335 is assembled to be locked to the unlocking frame portion 334 inside the button hole 334b so that it no longer comes out.

And the button 335 and the arm (335a) is the arm (335a) side of the band engaging button portion 337 bottom surface 337a so that the jersey wedge 336 is always kept locked with the locking wedge 333. In the state to be inclined close to the () side to the middle of the arm (335a) by a pair of support shafts 338 are connected to both standing frames (337b), respectively, and a pair of elastic shafts on both sides of the rear end of the arm (335a) ( 339 is configured to be connected to both standing frames 337b.

In addition, the elastic shaft portion 339 is an extension portion 339a extending outward from the end of the arm 335a and a bending portion 339b and the bending portion formed by bending at a right angle with the extension portion 339a. It is comprised so that the torsion part 339c may be bent again by 339b and formed integrally with the standing frame 337b.

Therefore, when the button 335 is pressed, the support shaft portion 338 is slightly twisted and the rear end of the arm 335a is lifted up. At this time, the extension portion 339a and the bent portion 339b of the elastic shaft portion 339 are slightly lifted and the torsion portion 339c is slightly twisted.

The support shaft portion 338 and the torsion portion 339c may be slightly twisted is not only formed of a synthetic resin material whose materials may be slightly twisted, but also an interval at which the arm 335a is lifted by one. Since it is only heard at very small intervals such as mm, even if the support shaft portion 338 and the torsion portion 339c are slightly twisted, no problem occurs.

Accordingly, when the pressing force for pressing the button 335 is released, the rear end portion of the arm 335a is lowered to the original position as the twisted support shaft 338 and the torsion portion 339c return to their original states. The wedge protrusion 336 is in a state of being caught by the locking wedge protrusion 333.

In FIG. 14, reference numeral 340 denotes a stopper protrusion that is locked to the unlocking frame portion 334 when the fixed band 332 moves so that the fixing band 332 does not move any further, and reference numeral 341 denotes a fixing band 332 passing through the unlocking frame portion 334. It shows a "b" shaped guide projection to be in close contact with the adjustment band 331.

The operation of the tightening and wearing means 330 will be described with reference to FIGS. 15 and 17.

As shown in FIG. 15, when the fixing band 332 is inserted into the unlocking frame part 334 while passing through the entrance hole 334a, the inclined surface 333b of the locking wedge 333 and the inner side of the jersey wedge 336 are provided. When the inclined surface 336b is brought into contact with each other and the fixing band 332 is moved to the right in FIG. 15, the inclined surface 333b of the locking wedge 333 is illustrated in the virtual line of FIG. 17A. As you push the jersey wedge 336 as it is moved.

When the fixing band 332 stops moving, the rear end portion of the arm 335a is always acted in the direction of the locking wedge 333 by the elasticity of the elastic shaft 339 so that the outer vertical surface 336a of the jersey wedge 336 is fixed. ) Has a state that is engaged with the vertical surface (333a) of the locking wedge protrusion 333 is to prevent the fixing band 332 from being separated from the unlocking frame portion (334).

Therefore, when the wearer pushes the fixing band 332 in the direction of the adjustment band 331 on the edge portion 51 of the hard hat 50, the jersey wedge 336 is automatically caught by the locking wedge 333. Unless the button 335 is pressed and released, it will not release itself.

At this time, as shown in Figure 2 so that the front edge portion 51 of the hard hat 50 is caught by the hard hat engaging jaw 13 and the fixing band 332 and the adjustment band 331 is the edge of the hard hat 50 ( When the fastening wearing means 330 is tightened in a state where it is placed on 51), it is not only tightly coupled to the hard hat 50, but also in the hard hat 50 during use because it is hung and hung on the rim 51. It will not flow down or break away.

Meanwhile, when the button 335 is pressed as shown in FIG. 17B, the rear end portion of the arm 335a is lifted so that the stop wedge 336 is separated from the locking wedge 333, thereby fixing the band 332. Becomes freely movable in the left direction or the right direction.

Accordingly, when the fixing band 332 is moved to the left side in the drawing while the button 335 is kept pressed, the fastening wearing means 330 is loosened or released.
