FIG. 1 is an explanatory view illustrating the structure of a protective surface 10 according to an embodiment of the present invention. As shown in FIG. 1, the protective surface 10 has a protective sheet 11 that allows the user to recognize the outside by the light that has passed, and at least the outer surface of the helmet so as to fix itself to a predetermined position of the helmet. A helmet fixing tool 12 that can be attached and detached, and a protection sheet fixing tool 13 that holds the protection sheet 11 and is connected to the helmet fixing tool 12 so as to be rotatable at least in a predetermined angle range.
The protective surface is a superordinate concept of the disaster prevention surface or the dustproof surface.

  The protective sheet 11 is provided with a plurality of holes 16 at the end attached to the protective sheet fixture 13. The protective sheet fixing tool 13 includes a plurality of fasteners 15 for fixing the protective sheet 11 with the holes 16. Thereby, when the protective sheet deteriorates, only the protective sheet can be replaced, which is economical.

  The protective sheet fixture 13 includes a hole (not shown) through which a bolt 12B for rotatably connecting to the helmet fixture 12 is passed.

  The helmet fixing tool 12 is connected to a helmet heel part (heel part) (not shown) by a groove 12A (FIG. 14) and fixed to the helmet fixing front part 12F, the helmet fixing tool front part 12F, and the connecting tool 12C. The helmet fixing tool 12S is made of an elastic body such as a spring. Both end portions 12E of the helmet fixture rear portion 12S are fixed by passing through the hole portions 12H of the connector 12C.

  The protective surface 10 is fixed to the helmet by fixing the front part 12F of the helmet fixture with the groove 12A on the bag in the front part of the helmet and pressing the rear part of the helmet with the elastic force of the rear part 12S of the helmet fixture. Is done. For this reason, this protective surface 10 can be used as it is for existing helmets of various sizes.

  The protective sheet fixture 13 to which the protective sheet 11 is attached is a state in which the protective sheet 11 covers the user's face around the position where the protective sheet fixture is attached to the helmet fixture 12 with bolts 12B, that is, the helmet fixture front part 12F. The state in which the protective sheet fixture 13 is lowered and fixed in contact with the front part 12F of the helmet fixture and the state in which the protective sheet 11 is raised and fixed on the helmet can be rotated.

  2 and 3 are views showing a state in which the protective surface 10 is fixed to the helmet 14 by the helmet fixing tool 12. FIG. 4 and 5 are views showing a state in which the helmet 14 with the protective surface 10 fixed is worn. The protective sheet fixture 13 is rotated with respect to the helmet fixture 12 to cover the user's face (FIGS. 2 and 4) and to the upper side of the helmet 14 (FIG. 3, FIG. 3). 5) and can be transitioned. As shown in FIG. 4, the protection sheet 11 is formed such that the lower end surface 11 </ b> A of the protection sheet 11 is located at a position that is the position of the user's jaw in the use state. The position of the chin can be predicted to some extent from the size of the helmet. Further, the position to be the position of the jaw may be near the position of the jaw. For example, it is included from the position expected to be the position of a general Japanese jaw to about plus or minus 3 cm.

  In a non-use state, a horizontal plane is maintained at the upper part of the helmet 14, and the work is not hindered by an upper protrusion or the like during field work. In addition, because of this length, in the non-use state, there is an effect that it does not protrude from the front surface of the helmet 14 and is easily stopped at the same position as the front surface of the helmet 14, thereby easily avoiding contact with an obstacle. .

  6 and 7 are diagrams illustrating a fixing method when the protective sheet 11 is fixed to the protective sheet fixture 13. The protective sheet fixture 13 includes a rotatable fastener 15. Further, the protective sheet 11 is provided with a hole 16 for fixing with the fastener 15. In order to fix the protective sheet 11 to the protective sheet fixture 13, the hole 16 of the protective sheet 11 is positioned at the fastener 15 of the protective sheet fixture 13 and is fixed by rotating the fastener 15.

  FIG. 8 is a diagram showing a state in which the protective sheet fixing tool is connected to the helmet fixing tool when the protective surface 10 is disassembled, and FIG. 9 is a diagram showing the protective sheet 11 when the protective surface 10 is disassembled. is there. The protective sheet 11 includes a front sheet 11C that covers the front of the user, a right sheet 11R that covers the right side of the user, and a left sheet 11L that covers the left side of the user. Further, the connecting portion between the front seat 11C and the right seat 11R is formed so as to be in the forward direction of the user as it goes downward in the use state.

  The protective sheet fixture 13 includes a rotatable fastener 15. Further, the protective sheet 11 is provided with a hole 16 for fixing with the fastener 15. Thereby, the protective sheet fixture 12 is formed so that the protective sheet 11 can be replaced.

  In order to fix the protective sheet 11 to the protective sheet fixture 13, the hole 16 of the protective sheet 11 is positioned at the fastener 15 of the dust-proof protective sheet fixture 13 (FIGS. 10 to 12), and the fastener 15 is It fixes by rotating (FIG. 13).

  FIG. 14 is a view showing a part of the helmet fixture 12. The helmet fixture 12 is formed with a groove 12 </ b> A for fitting into the helmet 14. As shown in FIGS. 2 and 3, the groove 12 </ b> A is fitted to the helmet 14, and fixed to the helmet 14 by the rear spring portion 12 </ b> S.

  With the above configuration, the lower end surface of the protective sheet is formed so as to be positioned at the position of the user's chin in the usage state. Therefore, it is possible to provide a protective surface that does not protrude into the surface and does not possibly come into contact with an obstacle during field work.

15-17, the light 17 is arrange | positioned in the front position of the helmet fixing tool 12, and the power source 18 for lighting at least the light 17 is arrange | positioned in the rear position of the helmet fixing tool 12. FIG. Is done. Thereby, work can be performed even at night. The weight can be balanced by the light provided at the front and the battery provided at the rear.
This light is disposed inside the protective sheet 11. Thereby, it is possible to prevent the light from being damaged by dust or the like.
The protective surface has a light shielding sheet, and the light shielding sheet can be attached to and detached from the inner surface of the protective sheet. The light shielding sheet can be used easily during welding.
Thus, by disposing the light shielding sheet on the inner surface of the protective sheet, it is possible to prevent the light shielding sheet from being damaged and deteriorated by dust or the like.

  The configurations, shapes, sizes, and arrangement relationships described in the above embodiments are merely schematically shown to the extent that the present invention can be understood and implemented, and the numerical values and the compositions (materials) of the respective components Is just an example. Therefore, the present invention is not limited to the described embodiments, and can be variously modified without departing from the scope of the technical idea shown in the claims.

  The protective surface of the present invention can be used for dust protection to protect the face from dust environment or for light shielding in welding operations. Furthermore, the protective surface of the present invention can be used for other disaster prevention and protection purposes.
