Description

Mask having Detachable Strap

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

In general, masks were mainly used in industrial sites where a lot of dust was generated, but as society became more complex, they were used in places where air pollution was severe, such as subway stations, busy downtown areas, or fire scenes, where toxic gases, dust, and bacteria floating in the air were used. The scope of use has been greatly expanded, including preventing harmful substances from penetrating into the respiratory tract and especially preventing damage from yellow dust, which has become more severe. Especially recently, the use of masks has become common to prevent infection by coronavirus.

The typical form of mask provided conventionally is a structure in which the filter body of the mask covers the wearer's mouth and nose, and the mask string is fastened to the wearer's ears. It covers most of the face and allows internal and external air to circulate only through the filter body, eliminating fine dust. Of course, the entry and exit of viruses 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 existing masks that are washed and reused.

However, since most of the disposable masks have a constant length of mask string and are formed with a circular cross-section, the tension of the string varies depending on the wearer, and because pressure on the wearer's ears is formed in the form of a line with a circular cross-section, when used for a long time, the wearer's ears are pressed by the string and cause pain. There is a problem that causes this.

In addition, the disposable mask can be replaced at any time, but in this case, the used mask is often discarded anywhere rather than in a designated place. The illegally disposed waste mask has a closed loop-shaped string, which is a problem that arises as one of the causes of threats to the survival of wild animals, such as being wrapped around the body of wild animals and restricting their wild activities.

Japanese Laid-Open Patent No. 8-191897 (published on July 30, 1996; hereinafter referred to as ‘Prior Document 1’) proposed a mask. In the preceding document 1, protrusions were formed on both sides of the filter unit of the central filter and a slit through which a string could be connected to the protrusions was provided. The preceding document 1 proposed a structure in which the string can be attached and detached, but it can be worn by connecting the string using a typical string knot method or a 曰 ring and adjusting the length of the string by adjusting the knot position and the combined position of the 曰 ring. The structure was presented. However, although the preceding document 1 can be reused by detaching the strap, there is the inconvenience of having to re-tie the knot to adjust the strap when worn, and the Waljahori also has the disadvantage that it is cumbersome to adjust the strap and its fixing force is weak, so it gradually loosens.

China Registered Utility No. 203563723 (registered on April 30, 2014; hereinafter referred to as ‘Prior Document 2’) presented a detachable mask. The preceding document 2 proposed a form of attaching the clip to the fitting by forming a mounting hole at the edge of the cover and fastening a button or forming a clip at the end of the string. The prior art document 2 also does not have a means for adjusting the string, so it cannot provide the function of attaching the filter cover to the face or automatically adjusting the tension of the earring string.

In this way, the previously provided mask provides a structure that allows partial attachment and detachment, but it was inconvenient to use because adjusting the strap length was quite cumbersome.

Therefore, the need for a new structure that allows the string length to be easily adjusted and the filter body, which is the filter part, to be easily replaced and the string to be used multiple times has emerged.

Japanese Laid-Open Patent No. 8-191897 (published on July 30, 1996): Mask China Registered Utility No. 203563723 (registered on April 30, 2014): Separate mask

The filter main body 20 is a filter that is composed of a plurality of filter layers and covers the wearer's mouth and nose and filters fine dust or fine water droplets contained in the passing air. The filter body can be formed in various shapes, such as a square bird's beak shape, depending on its shape, and can be configured for cold protection in addition to fine dust filtering.

The length adjustment means 30 is formed on the upper and lower portions of both sides of the filter body 20 to secure the string. The length adjustment means 30 is formed to be long from both edges of the filter body toward the front or center.

As shown in Figure 2a, the length adjustment 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 to allow the end of the string 40 to be hooked, or in various hooked forms.

In addition, the connecting pin 31 is formed to protrude greatly from the surface of the filter body 20 as shown, so that the coupling means 50, such as the ring portion 51, can be easily caught.

In addition, since the filter main body 20 of the present invention is composed of a thin multi-layer filter, even if the connecting pins 31 are formed in almost close contact with the filter main body, the filter main body between the connecting pins is connected using the coupling means 50 of the mask string. You can press it to secure space and then fasten it.

The string 40 has both ends joined at the top and bottom to the length adjustment means 30 disposed at the top and bottom on both sides of the filter main body 20 to form a closed shape so that it is hung around the wearer's ears. The string 40 is formed in the form of a string with a circular cross-section or a rectangular cross-section. Each of these mask strings 40 has a coupling means 50 formed at its end and is detachably coupled to a length adjustment means.

The length of the strap (40) is adjusted by forming a ring portion (51) that has a corresponding shape so as to be caught on a pin, and hanging the ring portion (51) on the connection pin (31) at an appropriate position among the plurality of connection pins according to the size of the wearer's face. This can be done.

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

As shown, the length adjustment means 30 according to another embodiment of the present invention can be formed as a movable support member 32 having a rail shape extending from both edges of the filter body 20 toward the inner center of the filter body 20.

The movable support member 32 is in the form of a rail formed in the front-back direction, and a portion of the movable locking member 52 is inserted inside to allow movement forward or backward.

When the movable support member 32 is mounted on the wearer, a movable groove 322 having a convex cross-section with an open portion exposed to the outside is formed to be long forward and backward, and the vertical width within the movable groove 322 is A locking protrusion 321 is formed on both sides of the wall to allow locking in only one direction, front or rear.

The locking protrusion 321 is designed to lock with a portion of the coupling means 50 inserted into the moving groove 322. It is formed in the form of a protruding sawtooth with a triangular cross-section and remains constant no matter which direction the coupling means is moved. The size can be adjusted. In addition, as shown in Figure 3c, one side of the cross section of the locking ledge 321 is formed as an inclined surface and the other side is formed vertically, so that the movable locking member 52, which is a mounted coupling means, exceeds the inclined surface of the locking ledge in one direction. It can advance and slide, but in the reverse direction, it can be caught on the vertical surface of the stopper and restrict movement. Therefore, the length of the strap 40 as desired by the wearer can be adjusted by attaching and moving the movable locking member 52, which is the coupling means 50 installed at the end of the mask strap 40, to the movable support member 32. there is.

To be more specific, the movable support member 32 has a wide bottom surface attached to the outer surface of the filter main body 20, as shown in FIG. 3b, an opening is formed in the outward direction on the opposite surface, and the movable support member 32 moves internally. It is provided with a structure in which a locking protrusion 321 is formed on the upper and lower side walls of the groove 322, and a coupling means 50 coupled to the end of the mask string 40 through the movable groove 322 inside the movable support member 32. ) can be slidably combined to adjust the length of the string.

The coupling means 50 can be formed as a movable locking member 52 that is partially attached and detachable to the movable groove 322 of the movable support member 32 and moves in the longitudinal direction to adjust the overall length of the string. .

As shown in FIGS. 3C and 3D, the movable locking member 52 includes a movable body portion 521 slidably inserted into the movable groove 322 of the movable support member 32; an elastic locking portion 522 extending in either the front or rear direction of the movable body; A movable handle 523 formed on the upper part of the movable body and having a hand grip surface 525 on the upper surface for resting the finger and pushing it in one direction to move it; It is configured to include a connecting portion 524 that spaced the movable body portion 521 and the movable handle portion 523 at regular intervals up and down.

The moving body portion 521 is narrow on the front side and expanded on the rear side to move forward in a narrow direction. The width of the movable body portion 521 is at least smaller than the width between the protruding portions of the locking protrusions 321 formed on both sides of the movable support member moving groove 322 to enable movement without being caught by the locking protrusions.

The elastic locking portion 522 is a curved plate-shaped elastic body that extends from both sides of the rear end of the moving body 521 to the rear side, and is formed to extend by gradually expanding the width direction spacing of the two elastic locking portions. The largest width of the space between the elastic locking portions 522 on both sides is at least larger than the width between the protruding portions of the locking protrusions 321 formed on both sides of the movable support member moving groove 322, so that when moving in one direction, the locking protrusion Pressure force is transmitted by the inclined surface, and the elastic locking portion 522 is elastically deformed inward to narrow the width between the two elastic locking portions to enable forward movement beyond the locking ledge.

Additionally, when moving in the reverse direction, the elastic locking portion 522 of the movable support member 32 is caught on the protruding vertical surface of the locking protrusion 321, thereby restricting its movement. Here, when both protruding sides of the locking protrusion 321 are formed with the same inclined surface, the elastic locking portion can move in both the forward and reverse directions by applying a force greater than the force that causes elastic deformation.

The movable handle portion 523 is disposed at an upper portion of the movable body portion 521 at a certain distance from the surface. On the upper surface of the moving handle 523, the front side is protruded to form a grip surface 525 that is caught when pushed to one side, so that sliding movement in the direction of applying force can be easily performed. . In addition, the distance from the movable body portion 521 is formed so that at least both sides of the open portion of the movable support member 32 can be inserted, so that the movable locking member 52 is connected to the opening of the movable support member 32. It can be configured so that it cannot be removed in the correct direction.

The connecting portion 524 is connected to maintain the gap between the moving body portion 521 and the moving handle portion 523. In the drawing, the connecting portion, the moving body portion, and the moving handle portion are shown to be formed integrally, but this is for convenience of manufacturing. It can be configured separately and integrated into one by combining.

As described above, the present invention can be configured by installing a movable support member 32 on the filter main body 20, and installing a movable 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 gradually shorten the length of the string 40, and in the reverse direction, the locking protrusion of the movable support member 32 (321) Reverse movement of the movable locking member is restricted by creating a lock due to the shape.

If the movable locking member 52 continues to move in the forward direction, it can be separated from the movable support member 32, and the length can be adjusted by reinstalling it at the opposite end.

In addition, the movable support member 32 is formed on the upper and lower sides of both sides of the filter body 20, but the rail-shaped movable support member 32 is formed only on one of the upper and lower parts, and is connected to the other side with a button. can be provided.
