Description

Mask having Detachable Strap

The present invention relates to a mask having a detachable string, and more particularly, to a mask having a detachable string that can be detached so that only the filter body can be replaced and the string can be used repeatedly several times. .

In general, masks have been mainly used in industrial sites where a lot of dust is generated, but as society becomes more complex, toxic gases, airborne dust, bacteria, etc. The scope of use has been greatly expanded, such as preventing harmful substances from penetrating into the respiratory tract and, in particular, preventing severe yellow dust damage. In particular, in recent years, the use of masks to prevent infection caused by the coronavirus has become common.

In the form of a conventional mask, the filter body of the mask covers the mouth and nose of the wearer and the mask strap is hung on the wearer's ear to fix it. Of course, the entry of the virus is also blocked to some extent.

As the frequency of use of these masks increases in daily life, the use of disposable masks is increasing rather than the existing masks that are washed and reused.

However, since most of the disposable masks have a constant length of the mask string and are formed in a circular cross section, the tension of the string varies depending on the wearer, and the pressure on the wearer's ear is made in a line shape having a circular cross section. There is a problem that causes

In addition, the disposable mask can be replaced from time to time, but in this case, the used mask is often thrown away without being disposed of at a predetermined place. The waste mask disposed of without permission has a closed spherical string, which causes a problem that emerges as one of the causes of threatening the survival of wild animals, such as restricting wild activities by being wound around the body of wild animals.

Japanese Patent Laid-Open Patent No. Hei 8-191897 (published on July 30, 1996; hereinafter referred to as 'Prior Document 1') suggests a mask. The prior document 1 provided a slit capable of forming protrusions on both sides of the central filtration part and connecting a string to the protrusions. The prior document 1 suggested a structure in which the string can be attached and detached, but the string is connected using a general string knot method or a wal-shaped ring, and the length of the string is adjusted by adjusting the knot position and the combination position of the wal-shaped ring. structure is presented. However, in the prior document 1, the strap can be separated and reused, but there is a hassle of having to re-tie a knot to adjust the strap when worn, and the walejagori also has a disadvantage in that the strap adjustment is cumbersome and the fixing force is weak, so that it gradually loosens.

China Registered Utility No. 203563723 (Registered on April 30, 2014; hereinafter referred to as 'Prior Document 2') suggested a detachable mask. The prior document 2 suggests a form of attaching the clip to the mounting hole by forming a mounting hole at the edge of the cover to fasten the button or form a clip at the end of the string. The prior document 2 also does not have a string adjusting means, so it cannot provide a function of adhering the filter cover to the face or automatically adjusting the tension of the earring string.

As such, the previously provided mask provides a structure that can be attached or detached in part, but it is inconvenient to use because adjusting the length of the string is quite cumbersome.

Therefore, as the length of the string can be easily adjusted, the need for a new structure that can use the string several times while easily replacing the filter body, which is the filter part, has emerged.

Japanese Patent Laid-Open Patent No. 8-191897 (published on July 30, 1996): Mask China Registered Utility No. 203563723 (2014.04.30.Registered): Detachable mask

The filter body may be formed in various shapes such as a rectangular bird beak type depending on the shape, and may be configured for cold protection in addition to filtering fine dust.

The length adjusting means 30 is formed on both sides of the upper and lower portions of the filter body 20 to fix the string. The length adjusting means 30 is formed to be elongated in the front or center direction from both edges of the filter body.

As shown in Figure 2a, the length adjusting means 30 of the present invention is provided in a form in which a plurality of connecting pins 31 are fixed in the longitudinal direction. The connecting pin 31 may be formed in a closed U-shape so that the end of the string 40 can be hung, and in various forms in which the hooking is made.

In addition, the connection pin 31 is formed to protrude greatly from the surface of the filter body 20 as shown, so that the coupling means 50, for example, the ring part 51 is easily caught.

In addition, since the filter body 20 of the present invention is composed of a thin multi-layer filter, even if the connection pin 31 is formed in a form that is almost in close contact with the filter body, the filter body between the connection pins is connected by the coupling means 50 of the mask string. It can be pressed to secure space and then tightened.

Both ends of the string 40 are vertically coupled to the length adjusting means 30 disposed up and down on both sides of the filter body 20 to form a closed shape so as to be caught in the wearer's ear. The string 40 is formed in a string shape of a circular cross-section or a rectangular cross-section.

The length of the string 40 is adjusted by hanging the hook portion 51 on the connecting pin 31 at a suitable position among a plurality of connecting pins according to the size of the wearer's face by forming a ring portion 51 having a corresponding shape to be caught on the pin. can make this happen

3A to 3D are a plan view and a cross-sectional view of a main part showing a length adjusting means and a string coupling means according to another embodiment of the present invention.

The length adjusting means 30 according to another embodiment of the present invention may be formed of a movable support member 32 having a rail shape elongated in the center inward direction from both edges of the filter body 20 as shown.

The movable support member 32 is in the form of a rail formed in the front-rear direction, and a part of the movable locking member 52 is inserted into the inside so that it can be moved forward or backward.

The movable support member 32 has a moving groove 322 having a convex cross-section with an open portion exposed to the outside when mounted on the wearer is formed long in the front and rear, and the vertical width within the moving groove 322 The locking jaws 321 are formed on both sides of the wall in the direction to be locked in only one direction of the front or rear.

The locking jaw 321 is to be engaged with a portion of the coupling means 50 that is inserted into the moving groove 322, and is formed in a sawtooth shape protruding in the shape of a triangular cross-section so that the coupling means is moved in any direction. A size jam can be made. In addition, as shown in Figure 3c, one side of the cross section of the locking jaw 321 is formed as an inclined surface and the other side is formed vertically, so that the moving locking member 52, which is a coupling means to be mounted, crosses the inclined surface of the locking step in one direction. It progresses and can be moved by sliding, but in the reverse direction, it can be caught on the vertical surface of the locking jaw to limit the movement. Therefore, by moving the moving locking member 52, which is the coupling means 50 installed at the end of the mask string 40, mounted on the moving support member 32, it is possible to adjust the length of the string 40 desired by the wearer. have.

In more detail, the movable support member 32 has a wide bottom surface attached to the outer surface of the filter body 20 as shown in FIG. 3B , and an opening is formed on the opposite surface in the outward direction, and internal movement The upper and lower sidewalls of the groove 322 are provided in a structure in which a locking jaw 321 is formed, and the coupling means 50 coupled to the end of the mask string 40 through the movable groove 322 inside the movable support member 32 . ) is slidably combined to adjust the length of the string.

The coupling means 50 may be formed as a moving locking member 52 that adjusts the entire length of the string while a part is inserted into and detachably attached to the moving groove 322 of the moving support member 32 and moved in the longitudinal direction. .

The moving locking member 52 includes a moving body 521 slidably inserted into the moving groove 322 of the moving support member 32, as shown in FIGS. 3c and 3d; an elastic engaging portion 522 extending in either direction of the front or rear of the movable body; a movable handle portion 523 formed on the upper portion of the movable body portion and having a hand rest surface 525 formed on the upper surface thereof to place a finger and push it in one direction to make movement; and a connection part 524 spaced apart from the movable body part 521 and the movable handle part 523 by a predetermined distance up and down.

The movable body portion 521 is formed in a narrow front side and an expanded rear side so that it moves forward in a narrow direction. The width of the movable body portion 521 is formed to be at least smaller than the width between the protruding portions of the locking projections 321 formed on both sides of the movable support member moving grooves 322 so that the movement is made without being caught by the locking jaws.

The elastic locking part 522 is a curved elastic body formed so as to extend from both sides of the rear end of the movable body 521 to the rear side, respectively, by gradually expanding the width direction of the two elastic locking parts. The maximum width of the gap between the elastic locking parts 522 on both sides is at least larger than the width between the protruding portions of the locking jaws 321 formed on both sides of the movable support member moving grooves 322. The pressing force is transmitted by the inclined surface, and the elastic locking part 522 is elastically deformed inward to narrow the width between the two elastic locking parts to enable forward movement moving over the locking jaw.

In addition, when moving in the reverse direction, the elastic locking portion 522 of the movable support member 32 is caught by the protruding vertical surface of the locking jaw 321 to limit movement. Here, when the protruding both sides of the locking jaw 321 are formed with the same inclined surface, the elastic locking part can move in both the forward and reverse directions when a force greater than the force that generates elastic deformation is applied.

The movable handle portion 523 is disposed on the upper portion spaced apart from the surface of the movable body portion 521 by a predetermined interval. On the upper surface of the movable handle portion 523, the front side is protruded to form a gripping surface 525, so that when pushed to one side, the gripping is made so that the sliding movement in the direction of applying the force can be made easily. . In addition, the distance spaced apart from the movable body part 521 is formed at a distance that at least both sides of the opened portion of the movable support member 32 can be inserted, so that the movable locking member 52 is inserted into the opening of the movable support member 32 . It can be configured so that it cannot be removed in the specified direction.

The connection part 524 is connected to maintain the distance between the movable body part 521 and the movable handle part 523, and the drawing shows that the connection part, the movable body part, and the movable handle part are integrally formed, but this is for the convenience of manufacturing. It can be configured separately for the purpose of being integrally formed by combining.

As described above, the present invention may be configured by installing the moving support member 32 on the filter body 20 and installing the moving locking member 52 at the end of the mask string 40 . The movable locking member 32 can be inserted into one end of the movable support member 32 and moved to the other side to provide a gradually shorter length of the string 40, and in the reverse direction, the locking jaw of the movable support member 32 . (321) By generating a lock by the shape, the reverse movement of the moving locking member is restricted.

If the moving locking member 52 is continuously moved in the forward direction, it can be separated from the moving support member 32, and the length can be adjusted by mounting it back to the opposite end.

In addition, although the movable support member 32 is formed in the upper and lower portions of both sides of the filter body 20, the rail-shaped movable support member 32 is formed only in one part of the upper and lower portions, and the other side is coupled by a button. can provide In this case, the button coupling part is fixed and the length of the string is adjusted in preparation for the amount of movement of the moving locking member only on the moving supporting member side.
