Description

  The present invention relates to a work mask wearing tool and the like that can remove a work mask such as a dust mask and a gas mask while wearing a helmet.

In view of the fact that there is still a high percentage of workers engaged in an environment that has adverse effects on the human body such as construction sites and not wearing a work mask, the inventor of the present application wears a work mask while wearing a helmet. An invention of a work mask wearing tool that can be removed has already been proposed (Patent Document 1).
JP 2007-75522 A

  However, although such a working mask wearing tool is very convenient and has gained popularity, there is a great individual difference in the position of the worker's mouth, so the working mask string and the working mask wearing In some cases, the tool is not necessarily in a straight line, and the work mask is not correctly attached. Therefore, it is necessary to make fine adjustments, for example, by devising how to attach the helmet to the edge, and this work is troublesome, which has an adverse effect on the improvement of the work mask mounting rate.

  However, if the design change is made so that the mounting angle to the helmet can be finely adjusted, the worker who made the fine adjustment can be used without any problems, but it will be used by another worker. Sometimes it is necessary to make fine adjustments again, which is not necessarily a radical solution.

  The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a working mask wearing tool that does not require fine adjustment of the angle of attachment to the helmet and a helmet using the same.

  A working mask wearing tool according to the present invention is a working mask wearing tool for connecting between a working mask and a helmet, and a first holding portion capable of holding an edge of the helmet is provided on one end side. And a second plate having one end side connected to the other end side of the first plate so as to be able to be folded and an end portion of the working mask being connectable to the other end side. The plate is provided with first fixing means for releasably maintaining the closed state in which the outer surfaces of both plates overlap each other, and the whole or part of the second plate is only open with respect to the first plate. Not only in the closed state, it is also rotatable.

  According to the present invention, the working mask is connected to the second plate, and is attached to the end portion of the helmet using the holding portion of the first plate. In this state, when the first and second plates are closed, the outer surfaces of both plates overlap each other, and accordingly, the distance between the helmet and the work mask is reduced, and the work mask is placed at the operator's mouth. Will be covered. In this process, the whole or a part of the second plate is pulled in the direction by being pulled by the work mask, and as a result, the whole or a part of the second plate and the end of the work mask are aligned. The work mask is correctly attached. On the contrary, when the first and second plates are opened, the distance between the helmet and the work mask increases, and the whole or a part of the second plate is moved downward by the weight of the work mask. As it tilts, the working mask hangs away from the operator's mouth.

  Therefore, even if there is a large individual difference in the position of the worker's mouth, the work mask can be correctly attached without fine adjustment of the angle of attachment to the helmet. Along with this, the usability is improved and it is possible to improve the wearing rate of the work mask.

  Preferably, the first fixing means includes a claw portion provided on the second plate, and the claw portion formed on the surface of the plate main body portion of the first plate and inserted in the claw portion. A configuration having an arc hole to be engaged is preferable.

  According to the present invention, since the claw portion serves as both the guide and the engagement piece, it has a simple configuration, and it is possible to reduce the cost in this aspect.

  As for the example of the second plate, one end side is connected to the other end side of the first plate so that it can be folded back, and one end side is rotatably connected to the other end side of the fixed plate portion and is used for work. It is preferable that the mask has a movable plate portion that can be connected to the other end side of the mask. Preferably, the fixed plate portion of the second plate may be provided with a stopper that contacts a part of the movable plate portion and restricts the rotation angle range thereof.

  According to this invention, since the rotation angle range of the movable plate portion is regulated by the stopper, even if the first and second plates are opened wildly, the movable plate portion is reliably stopped by the stopper. Accordingly, the work mask does not come into contact with the operator's chest or the like with a large force, and the usability is improved on this surface.

  For the second plate example, a main plate composed of a fixed plate portion and a movable plate portion is connected to one end side of the main plate so that it can be folded back, and a work mask string is passed to the other end side. What is provided with the subplate in which the hole for insertion to be formed was formed is good. In this case, the main plate and the sub plate are provided with a second fixing means for maintaining the closed state in which the inner surfaces of the two plates overlap each other in a releasable manner.

  According to this invention, since the string of the working mask is passed through the insertion hole formed in the sub-plate, the working mask is placed on the operator side when the first and second plates are open. It wo n’t get in the way. In addition, the work mask can be smoothly attached when it is in the closed state. In these aspects, usability is further improved.

  As an example of the second fixing means, the convex portion provided on the inner surface of the movable plate portion of the main plate, and the convex portion formed on the inner surface of the sub plate and engaged with the convex portion in the inserted state. It is good to set it as the structure which has the recessed part to do.

  About the example of a 1st plate, it is good to set it as the structure by which the holding | maintenance part was extended and provided toward the thickness direction of the plate main-body part.

  According to the present invention, since the first plate or the like can be kept away from the worker's face without causing any discomfort even when sweating during the work. Moreover, even a worker wearing glasses has almost no part in contact with the temples of the glasses, and the wearing feeling is improved. In these aspects, usability is further improved.

  About the example of the holding | maintenance part of a 1st plate, the base part arrange | positioned facing the downward direction along the edge part of a helmet, and the straight line standingly arranged inside this base part and contacting the inner side of the edge part of a helmet It is preferable to have a plate-like inner claw portion and an outer claw portion having a substantially cross-sectional plate shape that stands on the outside of the base portion and contacts the outside of the edge of the helmet.

  According to the present invention, since the edge of the helmet is sandwiched and held between the inner claw and the outer claw, the range of types of helmets that can be used is widened. Will be better.

  In the case of the first plate having such a holding portion, it is preferable that an annular cushion member for stably attaching to the edge portion of the helmet is passed through the outer claw portion and / or the base portion.

  According to the present invention, not only can it be stably attached to the edge of the helmet, but also the range of the types of helmets that can be used becomes wider by adjusting the thickness of the cushion member. Will be better.

  Moreover, when attaching to the edge part of a grooveless helmet, it is good to provide the 1st attachment member with the front-end | tip part which can hold | maintain the edge part of a grooveless helmet. In this case, a hole for mounting the base end portion of the first attachment member along the first plate from above is formed in the base portion of the holding portion of the first plate. Similarly, when attaching to the edge part of a grooved helmet, it is good to provide the 2nd attachment member which has the cross-sectional L-shaped front-end | tip part for hooking the edge part of a grooved helmet. In this case, a hole for mounting the base end portion of the second attachment member along the first plate from above is formed in the base portion of the holding portion of the first plate.

  According to these inventions, since it becomes possible to securely attach the work mask wearing tool to the end of these helmets regardless of the type of helmet with groove / non-groove, there is a range of types of helmets that can be used. It will become wider and more convenient in this respect.

  The helmet according to the present invention is the above-described working mask wearing tool respectively attached to the left and right ear parts of the edge of the helmet, and the work connected to the end of the second plate of each working mask wearing tool. And a mask. Further, the working mask wearing tool may be integrated instead of being attached to the right and left ear portions of the edge.

  According to these inventions, the same effects as those of the above-described working mask wearing tool can be obtained. That is, even if there is a large individual difference in the position of the worker's mouth, the work mask can be correctly mounted without fine adjustment. Along with this, the usability is improved and it is possible to improve the wearing rate of the work mask.

The sub-plate 22 is maintained in a releasable state.

  FIG. 8 is a side view and a front view of the attachment member 30. FIG. 10 is a schematic cross-sectional view of the first plate 10 showing how the attachment member 30 is mounted on the holding portion 12 of the first plate 10.

  The attachment member 30 is a component used when the work mask wearing tool 100 is attached to a helmet without grooves, and as shown in FIG. 8, a holding member 31 having a U-shaped cross section that can hold the edge a1 of the helmet A1. And a plate-like mounting member 32 that is formed in the lower portion of the holding member 31 and can be inserted into the hole 124 of the holding portion 12 of the first plate 10. A plurality of rows of triangular teeth 321 that can engage with the teeth 14 of the first plate 10 are formed on the outer surface of the mounting member 32.

  Although it is possible to attach the work mask wearing tool 100 to the edge a1 of the helmet A1 only with the holding part 12 described above, when there is a possibility that the work mask wearing tool 100 cannot be reliably fixed due to the difference in the type of the grooveless helmet, the attachment member 30. To use.

  In this case, as shown in FIG. 10, when the attachment member 30 is inserted into the hole 124 of the holding portion 12 of the first plate 10 from above, the teeth 321 of the mounting member 32 are engaged with the teeth 14 of the first plate 10. Combined. When removing the attachment member 30, the mounting member 32 is pulled out while slightly floating from the inner surface of the plate body 11.

  Since the holding member 31 of the attachment member 30 has a shape along the curved surface of the edge a1 of the helmet A1, the shape and size of the grooveless helmet are slightly changed together with the original function of the holding portion 12. Also, the edge a1 of the helmet A1 can be securely held.

  FIG. 9 is a side view and a front view of the attachment member 40. FIG. 11 is a schematic cross-sectional view of the first plate 10 showing a state in which the attachment member 40 is mounted on the holding portion 12 of the first plate 10.

  The attachment member 40 is a component used when the work mask wearing tool 100 is attached to a grooved helmet, and as shown in FIG. 9, a holding member 41 having an L-shaped cross section that can hold the edge a2 of the helmet A2. And a plate-like mounting member 42 that is formed in the lower portion of the holding member 41 and can be inserted into the hole 124 of the holding portion 12 of the first plate 10. A plurality of rows of triangular teeth 421 that can be engaged with the teeth 14 of the first plate 10 are formed on the outer surface of the mounting member 42.

  Although it is possible to attach the work mask wearing tool 100 to the edge a2 of the helmet A2 only with the holding part 12 described above, when there is a possibility that it cannot be reliably fixed depending on the type of grooved helmet, etc., the attachment member 40 To use.

  In this case, as shown in FIG. 11, when the attachment member 40 is inserted into the hole 124 of the holding portion 12 of the first plate 10 from above, the teeth 421 of the mounting member 42 mesh with the teeth 14 of the first plate 10. Combined. When the attachment member 40 is removed, the mounting member 42 is pulled out while slightly floating from the inner surface of the plate body 11.

  Since the holding member 41 of the attachment member 40 is shaped to press the edge a2 of the helmet A2 from above (see FIG. 11), the shape and size of the grooved helmet are combined with the original function of the holding unit 12. Even if the height changes slightly, the edge a2 of the helmet A2 can be securely held.

  A method of using the thus configured helmet A1 will be described with reference to FIG. First, the both ends of the elastic band 201 of the work mask 200 are connected to the work mask wearing tools 100, 100, respectively. At this time, as shown by a broken line in FIG. 7, after the end portion of the elastic band 201 of the working mask 200 is passed through the insertion hole 222 of the sub-plate 22 of the working mask wearing tool 100, for example, fixing of the main plate 21 is performed. The holes 2123b and 2123a are sequentially passed. Due to the hole shapes of the fixing holes 2123a and 2123b, the elastic band 201 of the working mask 200 does not easily come off.

  When it is necessary to use the attachment member 30, the attachment member 30 is mounted in advance on each of the work mask mounting tools 100, 100.

  Next, the worker puts on the helmet A1 and attaches the work mask wearing tools 100, 100 to the edge a1 of the helmet A1 so as to be inserted from the bottom while being slightly inclined while being opened. When the goggles 300 are used together with the work mask 200, the goggle 300 is attached by passing the stretchable band 310 of the goggles 300 through the notched hook hole 113 of the plate body 11. FIG. 1B shows this state.

  Then, when working, the main plate 21 is tilted toward the first plate 10 by holding the opening and closing presser pieces 2122 of the work mask wearing tools 100 and 100 with fingers, and the outer surface of the main plate 21 is moved to the first position. 1 on the outer surface of the plate 10. When the claw portion 213 of the second plate 20 enters the arc hole 13 of the first plate 10, the closed state of the first plate 10 and the second plate 20 is maintained by the elastic force of the claw portion 213.

  At the same time, the stretchable band 201 of the working mask 200 presses the sub plate 22, and thereby the sub plate 22 is brought down toward the main plate 21 and is closed. That is, the inner surface of the sub plate 22 and the inner surface of the main plate 21 overlap. When the convex portion 2121 of the main plate 21 enters the concave portion 223 of the sub plate 22, the closed state of the sub plate 22 and the main plate 21 is maintained by the elastic force of the engagement piece 2125 formed in the concave portion 223.

  When the first plate 10 and the second plate 20 of the work mask wearing tools 100 and 100 are closed as described above, the work mask 200 that has fallen by its own weight is directed toward the operator's mouth. It is pulled and finally attached to the operator's mouth. At this time, the movable plate portion 212 and the sub plate 22 are pulled by the elastic band 201 of the working mask 200 and are naturally tilted in that direction. As a result, the elastic band of the movable plate portion 212 and the sub plate 22 and the working mask 200 is obtained. 201 and a straight line. FIG. 1A shows this state.

  The reason why the movable plate portion 212 and the sub-plate 22 and the stretchable band 201 of the work mask 200 are in a straight line in this way is completely unrelated to the individual difference of the worker regarding the position of the mouth. In contrast, it is possible to correctly attach the work mask 200 without fine adjustment of the attachment angle to the helmet A1.

  Contrary to the above, when the work mask 300 is not used, the opening / closing presser pieces 2122 of the work mask wearing tools 100 and 100 are gripped with fingers, and the second plate 20 is tilted in the opposite direction. Then, the nail | claw part 213 of the 2nd plate 20 will remove | deviate from the circular arc hole 13 of the 1st plate 10, and the 1st plate 10 and the 2nd plate 20 will be in an open state by the dead weight of the work mask 20. FIG. Accordingly, the convex portion 2121 of the main plate 21 is disengaged from the concave portion 223 of the sub plate 22, and the sub plate 22 and the main plate 21 are opened due to the weight of the work mask 20.

  As described above, when the first plate 10 and the second plate 20 of the work mask wearing tools 100 and 100 are opened, the movable plate portion 212 and the sub plate 22 face downward due to the weight of the work mask 200. . Along with this, the working mask 200 falls away from the operator's mouth. FIG. 1B shows this state. The work mask 200 is located slightly in front of the face below the operator's chin, so that it does not get in the way.

  Further, when the helmet A1 is removed in the state shown in FIG. 1B, the work mask 200 comes into contact with the vicinity of the operator's chin, and the helmet A1 comes off from the work mask wearing tools 100 and 100. Along with this, the working mask wearing tools 100, 100 are removed together with the working mask 200 and the goggles 300.

  In addition, since the usage method of helmet A2 is also the same as the above, the description is abbreviate | omitted.

  As described above, even if there is a great individual difference in the position of the worker's mouth, unlike the conventional case, the work mask 200 can be correctly mounted without fine adjustment of the attachment angle to the helmet A1 or A2. Become. Since the first plate 10 and the second plate 20 are floating from the operator's face, there is almost no discomfort even if the operator sweats during use. There is no sense that the operator's entire head is tightened by the work mask 200 or the goggles 300, and the wearing feeling becomes very good. In particular, even an operator wearing spectacles has no part in contact with the temple of the spectacles, and the wearing feeling hardly deteriorates.

  Further, when attaching or removing the work mask 200 during work, it is not necessary to take off the helmet A1 or A2 each time. The same applies to when the goggles 300 are attached or removed. When the helmet A1 or A2 is removed with the work mask wearing tools 100, 100 attached, the work mask wearing tool 100, the work mask 200, and the goggles 300 are also removed together.

  Therefore, unlike the case of the conventional example, the usability is very good, and it is actually possible to significantly improve the wearing rate of the work mask 200 in an environment where the human body is adversely affected. Further, by using the attachment members 30 and 40 properly, it can be applied to both a grooveless helmet and a grooveless helmet, and the usability is also improved in this aspect. From the manufacturer's standpoint, if various attachment members are prepared, the range of the types of helmets to which the work mask wearing tool 100 can be applied is widened, and there is an advantage in reducing costs.

  The helmet A3 listed here is integrated with the helmet A3, rather than the working mask wearing tools 10 'and 10' mounted on the left and right ear portions of the edge a3. The working mask wearing tool 10 ′ is greatly different from the working mask wearing tool 10 described above in that the holding part 12 is not provided and one end side of the plate main body part 11 is fixed to the left and right ear portions of the edge a3 of the helmet A3. It is. Needless to say, the helmet A3 and the work mask wearing tool 10 'may be separated from each other and integrated with each other by screws or the like.

  Since the work mask wearing tool 10 'is fixed to the helmet A3 in this way, the attachment members 30 and 40 are not necessary. The rest of the configuration is exactly the same as that of the working mask wearing tool 10 described above, and the details thereof will be omitted.

  Note that the working mask wearing tool according to the present invention is not limited to the above embodiment, and a part of the second plate can be rotated with respect to the first plate not only in the open state but also in the closed state. As long as it is, you can make any design changes. As for the first plate, as long as the edge of the helmet can be held, the structure of the holding part, the overall shape, material, etc. are not questioned, and if the design is appropriately changed according to the type of helmet, etc. good. The second plate may be entirely redesigned so as to be rotatable with respect to the first plate. The second plate is connected to the first plate so that it can be folded back, and the end of the working mask is the other. As long as it can be connected to the end side, the presence / absence of the sub-plate, the connecting method of the plates, the connecting method of the work mask, the overall shape and material are not questioned. What is necessary is just to design suitably according to the kind of work mask. As for the first and second fixing means, any fixing method may be adopted as long as the closed state of both plates can be maintained releasably. For example, a magnet or a spring may be used.

  The helmet according to the present invention is not limited to the above-described embodiment, and as long as the work mask wearing tool is provided on the edge of the helmet, the fixing method, the fixing position, and the like may be appropriately changed according to the type of the helmet. It ’s fine. In particular, the working mask wearing tool is not completely fixed to the helmet body, and when the working mask wearing tool is not used, the working mask wearing tool may be provided so as to be freely opened and closed so that it does not get in the way. Moreover, it does not ask about the kind of work mask, and the presence or absence of goggles.
