Description

  Apparatus for adjusting the length of the mask band}

The present invention relates to a strap adjusting device for a textile mask, and more particularly, to a strap adjusting device for a textile mask that is attached to the side of the mask and the user can freely adjust the length of the strap that can be worn on the ear of the mask user. will be.

In general, a large amount of toxic gas is generated in the production environment of dust, such as in the paper mill, textile mill, quarry, etc., or in the working environment of various chemical plants and metal processing plants such as welding and plating. Continuous inhalation of these dusts and toxic gases can lead to respiratory diseases of the human body such as the lungs and can be fatal to the human body. have.

In addition, personal health from deterioration of the natural air environment such as yellow dust, which is often caused by climate change of the earth, air pollution due to rapid urbanization due to economic development, environmental pollution caused by population increase, and dust or bacteria generated from artificial work environment In particular, a mask is worn for the purpose of preventing and protecting respiratory diseases.

These masks have been used for a long time since the combination of wearing bands on both sides of the rectangular fabric has little effect to block yellow dust and fine dust, so the filter can block the entry of fine dust or harmful bacteria in the near root. Masks have been developed and used.

The general structure of the mask is that the band is formed on both sides of the mask body that covers the user's nose and mouth to wear the band hanging on the ear, the band is mainly used to elastically stretch the elastic band to improve the fit. .

However, the elastic band has a limit on the elasticity of stretching, and in setting the length of the band, the size of the wearer with a large face and the wearer with a small face cannot be measured. Due to the pain caused by the very uncomfortable, on the other hand, in the case of a wearer with a small face, the length of the band has a problem that the gap between the mask and the face is loosened, which does not effectively protect from harmful substances and dust.

Therefore, in order to solve the above problem, a control mechanism for adjusting the length of the band has been proposed. For example, Korean Utility Model Publication No. 20-2013-0000253 (mask having a band adjusting means) is provided with a band adjusting means provided with an adjusting clip on both sides of the mask body, while the band is attached to the adjusting clip, The length of is adjustable.

However, in the state where the band is fitted to the control clip, the flow of the band does not occur, so when adjusting the length, it can be seen that the band is used by fastening in a manner of adjusting and refitting the band in a completely separated state from the control clip. In other words, in order to adjust the length of the band, it is necessary to separate it from the adjusting clip, which means that the band length can be adjusted after removing the mask to adjust the band length as the band and the mask body are separated from each other during this separation process. At this time, if the adjustment is made in a state in which the mask is taken off, it may cause inconvenience such as adjusting again when it is not fitted again. This is due to the configuration that the control clip and the band is completely separated, it is difficult to adjust the band in the worn state, after all, there was an inconvenience in that it is necessary to repeatedly adjust the action to adjust the length to the wearer in the masked state.

On the other hand, Korean Utility Model Registration No. 321107 (hanger band adjusting structure of the dustproof mask) ultrasonically welds a separate finishing member on both sides of the dustproof mask, but a hook band is built into the inside of the finishing member by the bending pressure of the finishing part. The hook band is pulled by a predetermined tension or more, and the middle portion of the finishing portion is provided with a groove and a guide handle, and the length of the hook band can be adjusted by drawing the middle portion of the hook band by the groove. However, the hanger band adjusting device as described above is supported by the end of the finishing member, which is simply supported by the tension of the hanger band, which causes natural tension release due to facial facial movements such as the wearer's conversation when worn for a long period of time, and thus lowers the dust-proofing effect. Since the upper and lower parts are always made at the same time when adjusting the tension of the hanger band, it is very inconvenient when adjusting the tension of the upper and lower parts, and the need to loosen or repeat the hanger band again and the inconvenience of wearing and releasing and adjusting the tension. There was a problem.

In addition, the Utility Model Registration No. 335485 (hanger band adjusting device of the dust mask), the control device formed with grooves and guide handles on both sides of the mask is ultrasonic thermal welding, the tension of the hook band can be adjusted by the control device. Form an elastic piece having an operating protrusion on one side by cutting the upper and lower surfaces of the adjusting device, and forming a release preventing clip on the upper and lower ends, and forming the locking groove and the locking protrusion which are latched on each other at one end of the elastic piece. To form a space portion in the upper and lower portions of the elastic piece, and to form a groove in the front and rear of the elastic piece, the hook band is configured to be inserted bent along the groove and the space. Hanger band of the anti-vibration mask is inserted and fixed through the groove formed in the control and the resilient piece and the upper and lower portions of the resilient piece is adjustable by the operation of the resilient piece. In this case, the elastic piece is locked by the locking groove and the locking projection when not in use, and the pressure is generated. When the wearer pulls the operation protrusion formed on the elastic piece using the finger, the elastic piece is fixed out of the locking projection by the external force. It is opened at an angle to release the pressing force of the hanger band. This is because the manufacturing process of the mask and the control mechanism as a separate component material and then attaching the hanger band to both ends of the mask attached to the control device has a problem that the manufacturing process of the dustproof mask is lengthened and the manufacturing cost also increases.

In accordance with an example, a front view and a cross-sectional view of a string adjustment device.

1 and 2, the strap adjusting device 20 of the present invention is attached to the side of the mask body (10). Inserting grooves 12 are formed in the side of the mask body, by inserting the insertion pillars 28 formed on both sides of the strap adjusting body 21 in the insertion groove 12, the mask body 10 A strap adjuster can be attached. That is, the insertion pillars are formed on both sides of the other side of the string adjusting device so as to be inserted into the insertion groove 12 formed on the side of the mask body and fixed to the mask. A locking head portion is formed at an upper portion of the insertion pillar so as not to be easily removed after being inserted into the insertion groove 12 of the mask. The insertion groove 12 is not necessarily formed in the mask body 10, and when the insertion groove 12 is not formed in the mask body 10, the insertion pillar needs to be formed in the string adjusting device. In this case, the string adjusting device is directly attached to the mask body by the adhesive means or stitching.

Mask strap adjustment device of the present invention is a device for adjusting the length of the strap (or also referred to as 'band') that can be worn on the mask user's ear. As shown, the string adjusting device of the present invention has a substantially columnar shape having an elongated length, and has a structure in which a through hole 22 is formed in the longitudinal direction so that the string can pass therethrough. Naturally, the size of the through hole should be larger than the thickness so that the string can be easily pulled out.

One side of the string adjusting device is formed with a side hole 23 for fixing the string or releasing the string according to the position where the string passes. That is, the string is passed through the side hole 23, in which case the string is fixed so as not to be easily pulled out, and in any position is formed to release so that the string is easily pulled out.

According to the present invention, the side holes 23 are largely divided into three parts. That is, it is divided into the release part 24, the slit part 26, and the fixing part 27. As shown in FIG.

The release part 24 is a part formed in the center of a side hole, and is a part to which a string is loosened. That is, by moving the string to this position, the user can freely adjust the position of the string by pulling the string forward or pushing it backward. That is, the string may be pulled forward or pushed back by the small force of the user, so that the string is released, that is, the part that releases the force applied to the string. The height or width of the release is greater than the thickness so that the strap can be easily released.

In order to fix the string again in the state of loosening the string, the position of the string is moved toward the fixing part 27. The part corresponding to the passage connecting the fixing part 27 and the release part 24 is a slit part 26. )to be.

The slit portion 26 is formed to be long on both sides of the release portion, and serves as a passage through which the string moves when the string is moved sideways.

The slit part 26 is lower than the release part 24 and the fixing part 27, so that the slit part 26 can be crimped | bonded and it can hold | maintain a string. After the user adjusts the strap appropriately at the release part 24, the user moves through the slit part to the fixing part 27 to fix the strap. When the height of the slit part is high, the length may be changed in the process of moving the strap to the side. In order to prevent this, the height of the slit portion is low. That is, in order to prevent the string from releasing in the process of moving the string to the side (i.e., to prevent the string from being pulled forward or pushed back), the slit portion may be squeezed to grasp the string so that the release portion and the fixing portion It is preferable to form lower than height.

Fixing portions 27 formed at both edges of the side holes are respectively formed at the ends of both slit portions 26 to form a pair of fixing portions. Fixing portion 27 is a portion for fixing the string by pressing the string so that pressure is applied to the string. The fixing portion 27 has a substantially circular shape, the size of the inner diameter is larger than the height of the slit portion. This is to prevent the string from moving easily to the slit portion. That is, when the inner diameter of the fixing portion 27 is larger than the height of the slit portion, the fixing portion serves as a locking jaw to prevent the string from easily moving to the slit portion. If the user is forced to move the strap toward the slit while the strap is in the fixed part, the strap may move toward the slit.However, a general mask such as wearing a mask or removing a mask by hanging the strap around the ear In the case of use, the string is not easily removed from the fixing portion 27.

On the other hand, both ends of the string adjusting device body 21 is formed with a rounded round portion 22a having a low direction, such as the side hole 23, so that the string can be easily inserted and removed. The rounded portion 22a has a high curved portion and a constant curved portion at both ends such as a wavy pattern. It can be divided into elongated part to hang the strap and short part through the side hole. The elongated part to hang on the ear is not easily caught and can be easily pulled out and the strap is prevented from being damaged. As shown in the direction, a rounded round portion 22a is formed.

Preferably, as shown, the release portion 24 is inclined guide portion 25 is formed in both sides up and down. The inclined guide portion 25 adjusts the length of the string at the release portion, and serves to guide the string in an oblique direction to move toward the slit portion easily when moving to the slit portion. That is, the inclined guide portion 25 is to be able to move more easily when moving the string to the side. As shown, the inclined guide portion 25 is formed on both sides of the top and bottom, that is, a total of four inclined guide portion.

In addition, as shown, the slit portion 26 has a shape that increases in height toward the release portion from the fixed portion as a whole. The straps located on the release section have a large size of the slit section on the release section so that they can easily move to the slit section, and the straps located on the fixing section have a small size of the slit section on the fixing section so that they cannot be easily moved to the slit section. This is to make it as easy as possible when moving the strap from the release side toward the fixing part, and to form as difficult as possible when moving the strap from the fixing part side to the release part. That is, in order to be able to move only when the user forcibly moves.

4 is a view for explaining a process of adjusting the length of the string using a string adjusting device according to a preferred embodiment of the present invention.

Referring to Figure 4, it will be described a method for adjusting the length of the strap using the mask strap adjustment apparatus of the present invention.

First, referring to (a), the string 30 is fixed to the fixing portion of the side hole. In this state, the fixing portion is in a state of pressing the string, and the string is in a fixed state. Since the inside diameter of the fixing part 30 is larger than the side slit part 26, it does not move easily toward the slit part 26 unless a user forcibly moves to the side.

If, in order to adjust the length of the strap, as shown in (b), the user moves the strap 30 sideways to the slit portion 26 by a force. The string 30 is moved sideways in a compressed state. Push the string to the side until it stops and move it towards the release part 24.

As shown in (c), when the strap 30 is located in the release part 24, the length of the strap portion caught on the ear can be adjusted by pulling the strap forward or pushing backward. In this case, the string can be moved freely. (c) shows a shorter adjustment of the length of the strap on the ear by pulling the strap forward.

After the length of the string is properly adjusted in the state of (c), it is pushed laterally to the slit part 26 again, and then, as in (d), the string is completely positioned on the fixing part 27 again. In this way, the strap can be adjusted completely easily.

The mask strap adjusting device of the present invention can be used a variety of materials, such as plastic, metal, preferably a plastic material can be used.

Although embodiments of the present invention have been described above with reference to the accompanying drawings, those skilled in the art to which the present invention pertains may implement the present invention in other specific forms without changing the technical spirit or essential features thereof.
