Description

  The present invention relates to a dust mask.

  Facial masks that are worn by workers and the like to cover the nose and mouth in order to filter air and prevent dust and the like in grinding operations and the like are well known. These masks have one or more bands attached around the back of the head to hold the operator's nose and mouth in place, and extend from the left and right edges of the mask around the back of the wearer's ears. Masks with existing loop attachments for ear hooks are common.

When wearing these masks, it may be desirable to remove the nose and mouth covered parts when hydrating or relaxing during breaks.
In this case, turn the hand to the band on the back of the head and remove it, or turn the hand to the back of the left and right ears to remove it from the ear and remove the mask and hold the mask in your hand or somewhere It will be kept temporarily in a clean place.

  In order to eliminate the troublesomeness at the time of a break, for example, Patent Document 1 proposes a device having a drooping band that can be held around the neck when the mask does not cover the nose or mouth.

  However, the thing of patent document 1 does not change the effort which turns a hand to the back part of a right and left ear, and removes this from an ear when removing a mask. In addition, there is a case where dust or the like is attached around the neck at the time of work, and care is taken so that the dust does not adhere to the removed mask in the mask hanging state.

  Patent Document 2 is a cold protection mask. A neck pad that covers the neck is extended from the mouth pad.

  For example, when this is used as a dust mask, dust or the like does not adhere around the neck. However, in the case of the mask of Patent Document 2, in the case of FIG. 1, the hand is turned to the back of the head to remove the locking member, and the side that is in contact with the face is exposed to the outside and hung down. The concern for adhesion remains.

  The thing of FIG. 8 is provided with the elastic member in the right-and-left side part, expands to radial direction, and makes it easy to wear from the head. In this case, it is said that it is easy to wear from the head or to remove it completely above the head by stretching in the radial direction, but at the time of a temporary break, the part covering the nose and mouth is temporarily shifted and opened. No consideration or ingenuity has been seen for making it happen.

Special table 2001-507263 JP-A-62-243811

  An object of the present invention is to provide a dust mask capable of temporarily shifting and opening a portion covering the nose and mouth during a temporary break and preventing the adhesion of dust or the like on the portion.

  The invention according to claim 1 is a dust-proof mask in which a filter is attached to a mouthpiece portion to which a wearer's mouth is applied, and the tubular body including the mouthpiece portion covers the mouth from the wearer's mouth to the neck.

It is a side view of the form which equipped with the dust mask. It is a front view of the form equipped with a dust mask. It is a side view of the form which bent the dust mask under the jaw. It is a front view of the form which bent the dust mask under the jaw. 6 is a cross-sectional view of a dust mask according to Embodiment 2. FIG.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

First, Embodiment 1 of the present invention will be described with reference to the drawings.
As shown in FIG. 1, the dust mask 10 includes a cylindrical main body 11, a filter 13 attached to a mouthpiece 12 that is a part of the main body 11, and an upper portion 15 and a lower portion 16 of the filter 13. As shown, the filter 13 includes string-like members 17 and 17 serving as fastening members that are brought into close contact with each other by being pressed against the wearer.

  The main body 11 is formed by knitting a knitting yarn having elasticity such as wool yarn, lace yarn, silk yarn, embroidery yarn, and lilyan. The main body 11 knitted with these materials has flexibility. That is, the main body 11 is a flexible body using a stretchable material.

In addition to such knitting, felt, gathers, etc. can be applied to stretchable materials.
Compared to these, the knitted fabric has excellent stretchability and a good feeling of wearing, and can also be kept warm.

The filter 13 is mounted such that an air inlet 22 through which a wearer sucks air faces the outside through an opening 24 provided in a part of the mouthpiece 12. That is, a part of the filter 13 is exposed from the opening 24.
How to attach such a filter 13 will be described in detail with reference to the next figure.

FIG. 2 is a right sectional view of the main body 11 and a front view of the filter 13.
As shown in FIG. 2, on the inner peripheral side of the mouthpiece 12, a hook-and-loop fastener 26 </ b> R (R is a subscript indicating the right when viewed from the wearer. .) Is provided.
Although not shown in the drawing, a left side latching portion 26L (L is a subscript indicating the left when viewed from the wearer. The same applies hereinafter) is provided at the same position on the left side.

  On the other hand, hook and loop fasteners 27 </ b> R and 27 </ b> L are attached to positions on both sides of the filter 13 and corresponding to the retaining portion 26.

In order to attach the filter 13 to the main body 11, the filter 13 is held on the mouthpiece 12 by being pushed against the opening 24 from the inner peripheral side.
More specifically, the hook-and-loop fastener 27 is stopped by being pushed toward the hook-stop portion 26. At this time, a part of the filter 13 is exposed from the opening 24 toward the outside (left in the drawing), so that the opening 24 plays a role of positioning the filter 13. Since the filter 13 is positioned by the opening 24, the filter 13 can be easily mounted.

  In addition, the filter 13 is detachably hooked on the mouthpiece 12. When the appropriate replacement time for maintaining the filter function comes, it is economical to replace only the filter 13.

  Here, the main body 11 is composed of a double fabric of an outer peripheral fabric 28 and an inner peripheral fabric 29. The string-like member 17 is passed between the outer peripheral fabric 28 and the inner peripheral fabric 29. Even when the string-like member 17 is pulled, the inner circumference fabric 29 serves as a cushion because the inner circumference fabric 29 is sandwiched between the string-like member 17 and the wearer.

Furthermore, the length of the string-like member 17 exposed to the outside can be shortened by covering the string-like member 17 with the outer peripheral fabric 28. By preventing the string-like member 17 from appearing as much as possible, the appearance of the dust mask 10 is enhanced.
A method for mounting the dust mask 10 to which the filter 13 is attached will be described in detail with reference to the following figure.

  As shown in FIG. 3, the wearer Mn wears the dust mask 10 so as to cover from above. According to such a dust mask 10, it is possible to cover the wearer's mouth Mo to the neck Ne. This makes it possible to obtain a dustproof effect not only for dust scattered around the mouth Mo but also for dust scattered around the neck Ne.

  After covering the dust mask 10, the string members 17, 17 are pulled as shown by the arrows while pressing the button 33 of the stopper 32 attached to the string members 17, 17. Thereby, the main body 11 is contracted while being bent, and the filter 13 is brought into close contact with the wearer Mn.

  In addition, the string-like members 17 and 17 extend from the mouthpiece 12 toward the wearer's back head Ba, and turn the wearer's back head Ba. By moving (pulling) the string-like members 17, 17, the main body 11 contracts, and the filter 13 is brought into close contact with the wearer Mn. In order to improve the adhesion of the filter 13 to the wearer Mn, it is only necessary to operate the string-like members 17 and 17, and the operation is simple and beneficial.

In addition, string-like members 17 and 17 are provided from the upper part 15 and the lower part 16 of the filter 13 toward the back head Ba of the wearer. Compared to the case where the center of the filter 13 (for example, the upper surface of the air suction port 22) is pressed by the string-like member 17, the filter 13 is more closely attached to the wearer Mn when pressed from both ends of the upper portion 15 and the lower portion 16. it can.
In addition, with the configuration using the stopper 32, the close contact state can be easily maintained by simply opening the button 35, and it can be easily loosened by simply pressing the button 35.

The string-like member 17 includes a stopper 32 that stops the movement of the string-like member 17, a string that connects the string-like member 17 with the back head Ba of the wearer, and an engagement hole at the tip of the string-like member 17. You may attach and engage an engaging member.
In such a dust mask 10, a nose pad part 19 is provided on the upper part of the mouth pad part 12. The nose pad portion 19 will be described in detail with reference to the next figure.

As shown in FIG. 4, a nose pad portion 19 that extends substantially in the shape of a letter and covers the nose of the wearer is extended on the upper portion of the mouth pad portion 12. By extending the nose pad portion 19 upward in a substantially U shape, the dust mask 10 can be worn up to the wearer's nose without obstructing the wearer's field of view.
When the dust mask 10 is mounted, it is possible to prevent dust and the like from adhering to the neck portion from the mouth and nose.

  While wearing such a dust mask 10, there is a case where it is desired to remove the mouthpiece 12 from the mouth in order to take a break, for example. How to use the dust mask 10 in such a case will be described in detail with reference to the following figure.

  As shown in FIG. 5, when removing the mouthpiece 12 from the wearer's mouth Mo, the stopper 32 is moved as indicated by an arrow while pressing the button 33 of the stopper 32. By moving it, the contracted main body 11 is loosened. After loosening the main body 11, the wearer Mn lowers the dust mask 10 toward the neck Ne, so that the mouthpiece 12 can be easily bent below the wearer's chin Ch, and the wearer's mouth Mo The mouthpiece 12 can be removed.

  As shown in FIG. 6, the main body 11 is made of a stretchable material. Since the main body 11 has elasticity, the main body 11 expands when the mouthpiece 12 is applied to the mouth, and the main body 11 contracts when the mouthpiece 12 is bent below the jaw Ch. By expanding and contracting the main body 11, the mouth pad 12 can be removed from the mouth Mo of the wearer more easily.

  In addition, the stretchable material is knitting. That is, the main body 11 is made of knitted yarn. Since the main body 11 knitted with the knitting yarn covers the mouth Mo and the neck Ne of the wearer, the wearer Mn can obtain a good wearing feeling.

Furthermore, the dust mask 10 can cover the wearer's mouth Mo to the neck Ne. That is, adhesion of dust around the neck Ne is prevented. Thus, the wearer Mn can bend the mouthpiece 12 under the chin Ch without worrying about dust scattered around the neck Ne adhering to the filter 13.
Another embodiment of the dust mask 10 will be described with reference to the next figure.

Next, a second embodiment of the present invention will be described with reference to the drawings.
As shown in FIG. 7, the dust mask 40 does not have an opening (see reference numeral 24 in FIG. 1) in the mouthpiece 41.
Further, the latching portion 26 is provided so as to latch the filter 13 on the top and bottom.

  Also in such a dust mask 40, the mouth rest 41 can be removed from the mouth of the wearer by bending the upper end of the mouth rest 41 to below the wearer's chin. For this reason, the effect of the present invention that the mouth pad 41 can be easily removed from the wearer's mouth can be obtained.

  Furthermore, when no opening is provided, the wearer's mouth is covered with both the filter 13 and the mouthpiece 41. For this reason, compared with the case where it covers only with the filter 13, the replacement | exchange time of a filter can be made comparatively long and is more economical.

In the dust mask according to the present invention, the hook-and-loop fastener is used for the latching portion.
Further, the latching position may be, for example, a vertical position other than the left and right in the first embodiment, and may be disposed on the left and right in the second embodiment. In any of the embodiments, it may be arranged at four places on four diagonal sides.
In addition, it is desirable to arrange the latching portions symmetrically.
