Description

[Detailed description of the invention] Industrial application field This invention relates to the improvement of a fastener for fixing the inner body of a hard hat to the main body of the hard hat. This invention relates to a fastener for fixing the inner body of a safety helmet that can be worn.

Prior Art It is necessary to wear a dust mask or a gas mask when working in a place with a poor work environment where dust or toxic gases are present, but a hard hat is also often worn at the same time. Conventionally, when wearing a protective mask, as shown in FIG. 4, the protective mask 15 is tied to the top of the head 21 using rubber strings 16 and 18 and fixed at the back of the head 20, and a hard hat is also worn in this state. It was a lot.

Furthermore, as shown in Figures 5a and 5b, when attaching the dust-proof surface or welding surface 22 to the safety helmet 23, the holding fitting of the dust-proof mask is hooked onto the set screw 25 of the mounting fitting 24 (Jikkosho 43 -13699) or No. 6
As shown in the figure, the safety helmet 23 has a disaster prevention surface or a welding surface 2.
The dust mask 15 is attached to the holding piece 26 that holds the dust mask 2.
(Utility Model Publication No. 55-7533).

Problems that the invention aims to solve However, in the conventional example shown in Figure 4, there are inconveniences such as having to take off the hard hat to put on and take off the protective mask, and the straps of the protective mask being placed in the position where the head is fixed during work. This caused the inconvenience of the protective mask not being fully fitted as the protective mask would slip further.

In addition, in the conventional example shown in FIGS. 5 and 6,
It is not always necessary to wear a welding surface and a dust mask at the same time, and they are used for convenience.
The hooks were often unstable, and the latching work was often not easy.

Therefore, in order to solve the problems of the prior art when wearing a protective mask and a hard hat at the same time, the present invention aims to solve the problems of the conventional technology when wearing a protective mask and a hard hat at the same time. Focusing on the fact that the shock absorbing body 11 is molded from flexible synthetic resin, etc., and that the safety hat body 12 and the interior body 11 are fitted and fixed by rivets 28, buttons, etc., Another object of the present invention is to provide a fastener for fixing the inner body of a cap, which enables the secure and easy attachment of a protective mask by improving the rivets and the like for fixing the inner body of a cap.

Means for Solving the Problems The structure of the present invention for achieving the above object will be explained using FIGS. 1 to 3 for the embodiments. In the fastener to be fixed, the inner body is connected by a first shaft portion forming a first groove between a flanged end portion that locks on the inner surface of the inner body and an intermediate collar portion that locks on the outer surface of the safety hat main body. The fixing part is provided with a protective mask mounting fitting locking part that connects the intermediate flange and the flange-shaped head with a second shaft part that forms a second groove part.

Effect The present invention uses the above-mentioned means to pass the flanged end portion and the first shaft portion through the through holes of the safety helmet and the inner body, and when the flanged end portion is locked to the inner surface of the inner body, the intermediate flanged portion The back side of the helmet comes into contact with the outer surface of the safety hat body and is locked (the second
figure).

A second shaft portion and a brim-shaped head protrude from the outside of the safety hat main body, and a second shaft portion formed by the second shaft portion between the surface of the intermediate brim portion and the brim-shaped head portion protrudes from the outside of the hard hat main body. The mounting bracket of the protective mask can be locked in the groove.

Such fasteners can be attached to symmetrical positions on both sides of the hard hat to lock the attachment fittings of the protective mask and used as shown in FIG. 3.

Embodiments Hereinafter, embodiments of the present invention will be described with reference to the drawings.
In FIG. 1, 1 is a rivet according to an embodiment of the present invention;
Among the plurality of rivets installed at regular intervals around the lower part of the hard hat in order to fix the hard hat main body and the inner body, this invention was implemented for a pair of rivets located at symmetrical positions on both sides of the hard hat. For example, rivets can be used. 2 is a flanged end, 3 is a first shank, 4 is an intermediate flange, 5 is a second shank, and 6 is a flange head.

Then, the flanged end portion 2, the first shaft portion, and the intermediate flanged portion 4
The inner body fixing part A is formed by the rear surface 7 side of the inner body, and at the same time, the first groove part 8 is formed.

In addition, a protective mask mounting fitting locking portion B is formed by the surface 9 side of the intermediate collar portion 4, the second shaft portion 5, and the collar-shaped head portion 6.
is formed, and at the same time, a second groove portion 10 is formed.

For the inner body fixing part A, the rivet holes set in the existing hard hat can be used as they are, and the openings 13 and 14 of the inner body 11 and the hard hat body 12 are fixed to the flange. It is fitted and fixed in the first groove part 8 by the shaped end part 2 and the back surface 7 of the intermediate collar part 4.

In the case of the metal fitting locking part B, the metal fitting 1 is attached to the tip of the rubber string 16 for attaching the protective mask 15.
7 is fitted into a second groove 10 protruding from the outside of the safety hat main body 12 and hung from the second shaft 5.
Further, the metal fitting 19 of the other elastic cord 18 is fixed at the back of the head 20.

Effects of the invention As described above, by improving the shape of the rivet that fixes the inner body of the hard hat into the shape of the invention,
Not only can the protective mask be easily and reliably put on and taken off even while wearing a hard hat, but it also eliminates the discomfort of unnecessarily tightening the head and prevents it from slipping or slipping off. So,
It can be said that it is extremely effective for workers without causing any hindrance to their work.
