Description

Length adjustment mask {EARING BAND LENGTH ADJUSTABLE MASK}

The present invention relates to a mask, and more particularly, to a length-adjustable mask that is easy to adjust the length of an earring string of the mask and is easy to manufacture a length-adjusting structure.

In general, a large amount of toxic gas is generated in the working environment of paper mills, textile mills, quarries, etc., or in the working environment of various chemical plants and metal processing plants such as welding and plating. In case of severe inhalation of such dust or toxic gas, respiratory diseases of the human body, such as the lungs, etc., can be caused, and in severe cases, it is fatal to the human body. have.

As a dust mask used for this purpose, a mask with a cleaning material with a built-in anti-toxic material attached, or a product with a filter paper on the inside has been used. It is not only necessary to replace the dictatorship, but the filtration rate is not as satisfactory as expected, so it is often the case that a dust mask is used in a work environment where hygiene is important.

A wrinkled front part in which the front surface of the filter paper is bent several times with a dust-proof mask, a hard finishing part in which both sides of the filter paper are ultrasonically welded together with a hanging band, and a metal or freely bendable part formed on the upper part of the filter paper A plastic wire is provided to bend the metal or plastic wire to fit the contour of the user's face with severe curvature, as well as spread the folds on the front of the filter paper to evenly adhere to the wearer's nose and lower chin, increasing the dustproof efficiency A dust-proof mask has been devised.

However, such a conventional dust mask allows the length of the hanging band to be adjusted according to the face shape, which is a physical characteristic of the wearer. Alternatively, since the method of using it in a short bundle is chosen, it is very cumbersome because it is necessary to repeat inconvenient operations such as knotting the hanging band or releasing the knot at all times when wearing or releasing or adjusting the length to fit the wearer's body shape.

In order to solve the above problems, the previously applied and registered 'Structure for adjusting the hanging band of the dust-proof mask' is ultrasonic heat welding of separate finishing members on both sides of the dust-proof mask. By pressure, the hanging band is pulled by more than a certain tensile force, and a groove and a guide handle are formed in the middle part of the finishing part, and the length of the hanging band can be adjusted by drawing out the middle part of the hanging band by the groove. (Refer to Korea Registered Utility Model No. 321107).

However, the hanger band adjuster as described above is supported by the end of the finishing member in which the tension support of the hanging band is simple, and when worn for a long time or by the wearer's conversation, natural tension is released by the movement of the face, resulting in a decrease in the anti-vibration effect. In addition, since the upper and lower parts are always performed at the same time when adjusting the tension of the hanging band, when the tension of the upper and lower parts is selectively adjusted, it is necessary to unwind or pull the hanging band again. do.

In order to solve this problem, the previously applied and registered anti-vibration mask hanger band adjuster is ultrasonic heat-welded with grooves and guide handles formed on both sides of the mask, and the tension of the hanger band can be adjusted by the adjuster, The upper and lower surfaces of the adjusting member are cut to form a resilient piece having an actuating protrusion on one side thereof, and a separation prevention clip is formed at the upper and lower ends to form a locking groove and a locking protrusion that are interlocked with each other at one end of the elastic piece and the adjusting member, A space portion is formed in the upper and lower portions of the elastic piece, and a groove is formed on the front surface of the adjuster and the rear surface of the elastic piece, so that the hanging band is bent and inserted along the groove and the space (refer to Republic of Korea Utility Model No. 335485).

According to the above line registration, the hanging band of the dust mask is inserted and fixed through the groove formed in the adjusting member and the elastic piece and the space formed in the upper and lower parts of the elastic piece, and is adjustable by the operation of the elastic piece. At this time, when the elastic piece is not in use, it is locked and fixed by the locking groove and the locking protrusion to generate a pressing pressure. It is opened with an angle to release the pressing force of the hanger band.

However, according to this pre-registered patent technology, there are problems in that it is inconvenient to adjust the length of the mask, it is difficult to manufacture, and cutting and fusion of the mask itself is also very difficult, so there is a problem in that the manufacturing time and cost increase.
