Description

Mask that can adjust length of earring band {EARRING BAND LENGTH ADJUSTABLE MASK}

The present invention relates to a mask capable of adjusting the length of the earring band, and more particularly, when the length of the earring band is adjusted, the earring band easily moves, and when the length of the earring band is adjusted or when using a mask The present invention relates to a mask capable of erecting a length of an earring band having a structure for fixing the earring band not to move.

The mask has a different filter type and material depending on the purpose, but most of the mask is composed of a mask body that blocks the respiratory organs such as the mouth or nose, and an earring band that is provided on both sides of the mask body to be worn on the user's ear. The same is true in that respect.

Earring band is a band having a certain length is coupled to both sides of the mask body to form a closed curve serves to fix the mask body in front of the respirator by hanging the earring band on the user's ear. The earring band may be composed of an elastic band and an inelastic material. By the way, because the shape and size of each person and the distance between the respirator and the ear varies, it is difficult to use the length of the earring band difficult to use.

Korean Patent Publication No. 2018-0016192 (hereinafter referred to as 'prior art 1') and Korean Registered Patent No. 10-1072467 (hereinafter referred to as 'prior art 2') It is mentioned as an example.

The prior art 1 and the prior art 2 are both provided with a length adjusting portion on both sides of the mask body to which the earring band is coupled. The length adjusting part is configured to fold both sides of the mask body so that an end thereof is fixed or coupled to the mask body to form a band flow path therein. Thus, the earring band penetrates the band flow path and is configured to be fluidly coupled. In the above configuration, the middle portion of the length adjusting part is partially cut to expose a part of the earring band penetrating the inside of the length adjusting part to pull the exposed earring band, thereby reducing the length of the earring band. It is possible.

However, in the case of the prior art 1, since the earring band pulled is not particularly fixed, there is a problem that the mask is loosened by coming back to the original position every time the face is moved or the mouth is moved. In order to solve this problem, the prior art 2 is to form a pressure regulating concave-convex 17 inside the length adjusting portion. It is characterized in that the earring band passing through the pressure adjustment irregularities to face each other so as not to be easily moved while being caught or pressed by the pressure adjusting irregularities.

However, the prior art 2 has a problem in implementing the function of pressurized irregularities in manufacturing or structure. First, in view of the manufacturing process, the pressure regulating recesses of the related art 2 are disclosed to be manufactured by ultrasonic fusion. Ultrasonic welding is used to bond several filter layers when manufacturing a mask, and in particular, in the case of a dustproof mask composed of a thin nonwoven fabric and a filter, ultrasonic welding is often used to fix multiple layers of nonwoven fabric or filter layers. Therefore, it is theoretically possible to form protrusions on the object by adjusting the shape of the jig used for ultrasonic welding. By the way, since the main body of the anti-vibration mask is formed in the form of one or two thin filter layers inside the thin nonwoven fabric layer, projections are hardly formed even when the mask body is pressurized by ultrasonic welding. That is, even if a jig capable of forming the projections is used, sufficient material for forming the projections cannot be made during the fusion process. In addition, when ultrasonic welding is performed by pressing both sides of the mask body with a jig, it is common that the welding part is compressed and thinner than the surroundings. Therefore, it is difficult to realize irregularities of the same type as in the prior art 2 unless additional fusion is added to form additional convex and concave portions with the fusion jig. In the case of adding and fusion of a separate material, the manufacturing process becomes complicated, and surplus material affects the surrounding area, which causes a problem in that it is difficult to manufacture in a desired form.

In addition, in terms of the structural aspect of the prior art 2 is uneven portion is difficult to secure the earring band. The uneven part 17 is provided in both sides with respect to the bending line 15a of the center part. However, in order for the bent line to be smoothly folded, the uneven parts of both sides should be spaced to some extent from the bent line. However, in most dust masks, the earring band has a property of thinning as it is stretched as it is pulled, and thus, in the structure as in the prior art 2, the earring band is located between the folded portions on both sides of the folded band, making it difficult to be crimped. In addition, as described above, the fusion region becomes thinner when pressed, and the nonwoven fabric and the filter layer are formed in the periphery, so that even if the uneven portion is formed, it is difficult to produce a better friction or pressure effect than the surrounding mask body.

1 is a view showing the configuration of the mask is adjustable length of the earring band according to the present invention, Figure 2 is a perspective view showing the configuration of the locking projection shown in FIG.

1 and 2, the mask is adjustable length of the earring band according to the present invention is a mask body 100, the length adjusting unit 130 provided on both sides of the mask body 100, and the length It consists of an earring band 190 that is coupled to flow through the adjuster 130, the center portion of the length adjuster 130 is provided with a band exposure portion 150, the length adjuster 130 The inner side of the locking protrusion 170 is provided.

The mask body 100 has a front cover 103 formed long in the horizontal direction (refers to the left and right directions when the mask is worn on the face) and an upper cover 105 provided above the front cover 103 and the It consists of a lower cover 107 provided in the lower portion of the front cover (103). In addition, the upper cover 105 is provided with a shape fixing wire 109 such as metal or plastic in the transverse direction. In the above configuration, the front cover 103 is located in front of the respirator, the upper cover 105 is located in the nose, the lower cover 107 is located along the contour of the jaw. Thus, the front cover 103 is worn in front of the respirator while being supported by the upper cover 105 and the lower cover 107 while being spaced apart in front of the nose and mouth (hogong). At this time, the shape fixing wire 109 is bent to correspond to the shape of the nose and the face is in close contact with the top cover 105 is fixed while being tightly attached to the front of the face is covered with a structure that blocks the respirator from the outside air. Earring bands 190 are provided at both sides of the mask body 100 to fix the mask body 100 to the front of the face by hanging the earring band 190 on both ears.

As described above, the general configuration of the anti-vibration mask is exemplarily described, and the specific shape or structure of the mask body 100 may be configured in various shapes without affecting the interpretation of the scope of the present invention.

The length adjusting part 130 is folded while being fused to both sides of the mask body 100 in the middle direction and fused to the mask body 100. The mask body 100 is generally provided with one or a plurality of filter layers (not shown) inside the nonwoven fabric layer. The mask body 100 as described above is bonded by ultrasonic welding along the dotted line shown in the figure to form a shape and is coupled between the filter layer and the nonwoven layer. The length adjusting part 130 is folded in both directions of the mask body 100 in the center direction so that the band flow path 131 is formed on the inner side when the end is joined by ultrasonic welding in a state in which the end faces the mask body 100. . Inside the band flow path 131, the earring band 190 is coupled to flow while passing.

A band exposure part 150 is formed in the center portion of the length adjusting part 130 in the width direction (up and down direction in FIG. 1), and the band exposure part 150 is formed of two layers of the length adjusting part 130. A portion of the band flow path 131 is exposed by cutting a portion so that the earring band 190 passing through the inside is partially exposed.

Earring band 190 to be applied to the present invention is formed of synthetic fibers formed of an elastic rope structure penetrates the band flow path 131 and both ends are joined to form a closed curve. The earring band 190 coupled to the length adjusting unit 130 is exposed to the outside in the band exposure unit 150 section, as shown in the figure and both sides of the band exposure unit 150 to the length adjusting unit 130. It is covered and supported. Therefore, when the user pulls the earring band 190 exposed to the band exposure unit 150 with a finger, both sides of the band exposure unit 150 come out and the earring band 190 between the ear and the mask body 100 is reduced in length. Adjustment is possible.

One end of the length adjusting unit 130 is fixed together at the junction of the length adjusting unit 130, the other end is composed of a free end, and the end is provided with a locking protrusion 170 is formed with a jagged projection. . As described above, the length adjusting unit 130 is folded at both sides of the mask body 100 in the center direction based on the second bend line 135 to bond the ends to the mask body 100 by ultrasonic welding. The locking protrusion 170 is fused so that one end thereof overlaps with each other when the length adjusting part 130 is formed inside the length adjusting part 130. The sawtooth-shaped protrusion formed at the end of the locking protrusion 170 is inclined in the direction of the band exposure part 150 so that the earring band 190 is more easily caught when the band is moved outwardly from the band exposure part 150. In the case of moving inwardly (in the band exposure part 150 direction), it is preferable to make it move smoothly while sliding.

The locking protrusion 170 is configured to be bent in a bellows structure while going in the width direction (the band exposure part 150 direction from the outside). At this time, the bellows structure is such that the bending width of the bellows structure becomes wider toward the band exposure unit 150. In one embodiment of the present invention, the locking protrusion 170 is configured to cut a portion of the width direction, and more preferably, is cut in the direction of the band exposure unit 150 as shown in the figure. By forming the cutout 175 in the locking protrusion 170, the bellows structure formed in the other direction of the cutout 175 can be easily unfolded or folded. In this case, the bellows structure of the locking protrusion 170 may be formed only in the other direction of the cutout 175.

3 is a view showing the configuration of the unfolded state of the length adjuster shown in FIG.

Looking at the formation process of the length adjusting unit 130 according to the present invention with reference to Figure 3, first, both ends of the mask body 100 as shown in FIG. In other words, the end of the mask body 100 is cut into a sawtooth shape, and cut and cut similarly to the U-shape inverted convexly in the end direction with respect to the center portion of the second bend line 135. Thereafter, the outside of the virtual first bent line 133 is crimped by fusion processing to form the locking protrusion 170. In this case, as described above, the locking protrusion 170 forms the cutout 175 on the outer side of the first bent line 133 and is formed to be bent into the bellows structure on the outside of the cutout 175. When the end of the mask body 100 of a flexible and soft material such as a non-woven fabric or a filter is fused and compressed, it is hardened hardly to form a rigid locking protrusion 170.

After forming the locking protrusion 170, the first bending line 133 is first folded, and the second bending line 135 is secondly folded based on the inside of the first bending line 133 and the mask body. When the 100 is fused and fixed again, the length adjusting unit 130 and the locking protrusion 170 as shown in FIG. 1 are formed.

The distance between the end of the locking protrusion 170 and the other inner side of the length adjusting part 130 is the length of the earring band 190 in the state in which both side walls of the length adjusting part 130 are facing, the diameter shrinks. It is wider than the state and the length of the earring band 190 is contracted so that the diameter of the state beam returned to its original shape is narrow.

As described above, the earring band 190 is made of elastic synthetic resin. Accordingly, the diameter of the earring band 190 increases in the longitudinal direction, and the diameter of the earring band 190 is reduced while the external force in the longitudinal direction is removed from the earring band 190. This is to ensure that the earring band 190 is not tight to the ear and the skin while being somewhat tightened and elastically fixed to the ear. For example, in the case of the earring band 190 manufactured by the applicant of the present invention, the external force is not applied, that is, the diameter before the diameter is contracted is about 2.5 mm, and the diameter of the earring band 190 is increased in the longitudinal direction. If this contraction is reduced to about 1mm. Therefore, in accordance with the above criteria, between the end of the locking protrusion 170 and the other inner wall of the length adjusting part 130 may be configured to be larger than 1mm and smaller than 2.5mm. However, the above numerical values are exemplary, and may be further relaxed in consideration of the expansion of the length adjusting part 130 by the locking protrusion 170 as described below.

4 is a view showing the operation configuration of the mask is adjustable length of the earring band according to the present invention.

Referring to Figure 4, the mask is adjustable in the length of the earring band according to the present invention in the structure described above, when no external force is specifically applied to the earring band 190, the diameter of the earring band 190 is in a normal state The lower part of the earring band 190 is fixed while being caught by the end of the locking protrusion 170. At this time, as described above, the locking protrusion 170 is formed in a bellows shape so as to widen both side walls of the length adjusting part 130 while the other inner wall of the length adjusting part 130 is close to the locking protrusion 170. To lose. When the inner wall of the length adjusting unit 130 widens and the gap between the end of the catching protrusion 170 and the earring band 190 is narrowed, the earring band 190 may be firmly caught by the catching protrusion 170 with a higher probability. have.

On the other hand, when the user pulls the earring band 190 exposed to the band exposure unit 150 to adjust the length of the earring band 190, the earring band 190 is stretched in the longitudinal direction and the diameter shrinks. In addition, the length adjusting part 130 is also pulled up in the other direction along with the earring band 190, and the bellows structure of the locking protrusion 170 and both side walls of the length adjusting part 130 are contracted. As such, the diameter of the earring band 190 shrinks, and both the bellows structure of the locking protrusion 170 and both walls of the length adjusting part 130 are narrowed, and the other inner wall of the band flow path 131 is far from the locking protrusion 170. Ground The earring band 190 is easily adjustable while the length of the flow. In addition, since the tooth structure of the locking protrusion 170 is configured to be inclined in the direction of the band exposure portion 150 as described above, even if a part of the earring band 190 touches the end of the locking protrusion 170. It can slide and flow. When the external force is removed after adjusting the length of the earring band 190, the diameter of the earring band 190 is increased again, and the width direction of the locking protrusion 170 is widened, and the earring band 190 and the locking protrusion 170 are expanded. As the distance between them is close, the earring band 190 may be fixed while being firmly caught by the locking protrusion 170.

5 is a view showing the configuration of the length adjusting unit according to another embodiment of the present invention, Figure 6 is a view showing the well of the length adjusting unit according to another embodiment of the present invention.

First, referring to FIG. 5, the length adjusting part 130 according to another embodiment of the present invention may further include an elastic band 200 inside the band flow path 131. The elastic band 200 is configured such that both ends are fixed to the mask body 100 while forming a ring shape so as to correspond to an inner shape of the band flow path 131. Thus, the ring portion of the elastic band 200 is coupled to flow while the earring band 190 penetrates. And the inside of the elastic band 200 is provided with a locking projection 170 as in the embodiment described above.

 In the above configuration, when the user pulls the earring band 190 to adjust the length of the earring band 190, the elastic band 200 is extended and the diameter of the earring band 190 is contracted while the earring band 190 is The distance between the locking protrusions 170, the earring band 190 can be easily adjusted while the flow length. When the length adjustment is completed and the external force is removed from the earring band 190, the elastic band 200 contracts and pulls the earring band 190 in the direction of the locking protrusion 170, and the diameter of the earring band 190 is intact. As it becomes larger, it may be fixed to the locking protrusion 170.
