Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 This invention facilitates the use of dust masks and other masks currently used in industry and other places where dust is generated and enhances their functions.

[0002]

[Prior art]

 The conventional method of attaching a mask is as follows: a helmet or a rubber strap is looped over the head, a stopper is made, and the stopper is used as a stop. Because the back of the neck is tight, the neck is cramped and the body is tired. Therefore, it cannot be used for a long time. When the set is made because the tightening rubber cord is a continuation of one piece. When mounting the stopper above the head or when adjusting the contact surface between the mask and the face, etc. The stopper is fixed with two elastic cords, so it is not stable and loosens or comes off. Especially when working directly with a helmet attached to the head, the helmet comes off. Every time the neck is moved up and down and left and right, it is pulled by the rubber cord, creating a gap in the contact surface between the face and the mask, resulting in poor airtightness. I often remove it from my face during work and hang it on my neck.

[0003]

[Problems to be solved by the invention]

 The purpose of the present invention is to provide a method for mounting a dust mask which solves the above problems.

[0004]

[Means for Solving the Problems]

 This invention, which achieves the above object, is characterized in that the fastening part is not wrapped around the neck but is put on the chin and is fastened on the head, and that the tightening strength of the mask can be finely adjusted.

[0005]

[Embodiment of the Invention] The dust mask installation method of the invention is fastened to the head with four tightening rubber cords, the rear two are hung on the chin and fastened on the back of the head, so that it does not loosen even in a violent operation. In addition, the movement of the neck up, down, left and right is free, and the movement of the body becomes easy. Fine adjustment of the tightening strength is done by tightening the rubber cord with a looped string provided on the back of the chin.

【Example】

 FIG. 1 is a front view of an assembly of a rubber strap for tightening a dust-proof mask, 1 is a mask, 2 is a stopper string attached on a head and a helmet, 3 is a stopper adjustment section, 4 is a front fastening rubber string, 5 is a hook for attaching a rubber string, and 6 is a hook. The rear tightening rubber cord, 8 is adjusted by the tightening elastic string length adjusting unit, and the thickness of the head and the helmet is adjusted by the stopper adjusting unit 3. The rubber straps 4 and 6 are attached to the stopper and hooked to the hook of the mask so that the length can be adjusted. However, the tightening rubber strap assembly shown in Fig. 1 is divided into two parts for the helmet and those directly attached to the head. If you make a kind, the adjustment part of 8 is unnecessary. 10 is a mark for the length of the tightening rubber strap, the length of the rubber strap is different when using the head directly from the top of the helmet. Apply eight marks on the rubber strap in advance. Fig. 2 is a side view of the installation of the dust mask. Assemble it in advance as shown in Fig. 1 and set it lightly as shown in the figure. The adjustment string adjusts the tightening strength of the mask, and the 7 string also serves to prevent the 6 rubber band from coming off the chin. FIG. 3 shows the back of the chin, with the mask set, and 9 shows a tightening string adjustment stopper. FIG. 4 shows a rubber cord adjusting cord 6. Fig. 5 shows that the dust mask and the stopper attached to the helmet are tightened down with four rubber cords, so they do not come loose or come off during use. FIG. 6 shows a conventional method for mounting a dust mask. This invention can take the following embodiments. 1. This mounting method is not limited to the type of mask. 2. The material of the stopper string is not limited, and rubber, nylon, cloth, etc. can be used.

[0007]

[Effect of the invention]

 The method of mounting the dust mask of this invention does not cause cramping when the mask is mounted because the tightening part is performed not on the neck but on the head, so there is no fatigue of the body even if it is used for a long time, and there is a gap on the contact surface even in severe operation Since it does not, the airtightness is good and the functionality of the mask is enhanced. The stopper strap of No.2 has 4 or 6 fastening rubber straps fixed, so it is easy to handle at the time of setting, and it does not come off even if it comes into contact with objects during work. Since there is no cramping and pain during the work, the usage rate in the workplace increases.
