Description

The present invention adjusts the degree of adhesion of the mask covering the mouth and nose to the face to prevent cold, flu, and other diseases, thereby reducing the gap between the mask and the face. It relates to the adjustment tool.

Commercially available masks are off-the-shelf and rarely fit perfectly on the user's face, creating gaps between the mask and the face, and splashes and viruses invading there. In order to solve the problem by adjusting the degree of adhesion between the mask and the face by adjusting the tension of the string on the ear or head in order to fix the mask to the face, the aforementioned gap is eliminated. -185027 and JP-A-11-206896.

In JP-A-07-185027 and JP-A-11-206896, the mechanism for adjusting the tension of the cord is required to be provided on “both” of the left and right ear straps which are part of the mask function. Because, for example, when the adjustment mechanism is provided only on the right side and the tension of the right ear strap is increased, the mask is attracted to the right side of the face and is not properly attached to the face, and a new contact surface is formed on the contact surface between the mask and the face. This is because a gap is created and the warp is counteracted.

In order to prevent such problems, the adjustment mechanism is provided on the “both left and right” ear straps at the manufacturing stage, and the mask user adjusts the tension of the ear straps at two positions on the left and right sides during use. There was an effort to equalize the tension balance of the two hook straps so that only the one side worked and the mask did not shift from the center of the left and right.

In general, even when wearing a mask, it is often necessary to take off the mask during meals, hydration, taking medicines, etc., and once it is done, it will be worn again. At that time, a person who uses the mask with a high degree of adhesion needs to adjust the tension of the string every time it is attached or detached, such as loosening the tension of the string when removing it and increasing the tension when reattaching. The labor of the prior art described in [0004] is further increased due to this iterative work.

Furthermore, since the adjustment mechanism is provided as an accessory to the mask in the prior art, a process and cost for mounting the function are always required in the manufacture of the mask regardless of whether or not the user needs the function. However, due to the cost burden, there is also a drawback that the commercial price is remarkably higher than a mask not having the adjusting mechanism. This is a cost that is completely meaningless for users who do not need the adjusting mechanism, and also contributes to waste of waste and resources that are unnecessary from the viewpoint of global environmental protection.

The present invention is an auxiliary tool independent of the mask. Then, the strap was engaged or entangled with the pair of left and right ear straps of the mask at the position of the back of the user. Further, the right and left ear straps can be pulled toward each other by adjusting the engagement relationship and the length of the strap, thereby increasing the tension of the ear straps and maintaining the state. And a mechanism for returning the amplified tension to the original, and the degree of adhesion of the mask to the face was adjusted in one place.

Adjusting the tension of the left and right ear straps with a single operation has greatly reduced the man-hours required for adjustment and improved operability (no need to adjust the left and right tension balance). In addition, in the prior art, the tension adjusting mechanism of the ear strap was also discarded along with the discard of the mask. However, according to the present invention, it is not necessary to discard the adjusting mechanism, so both the waste reduction and the resource saving are achieved. Contributed. Furthermore, the mask body does not require the production of the adjusting mechanism, which contributes to cost reduction (for the mask body) and reduction in commercial price.

On the other hand, when the present invention is combined with a mask having no adjustment mechanism, the user spends only one embodiment of the present invention, whereas in the case of the prior art, the mask is not required. Since the material cost and processing cost of the adjusting mechanism, which has been passed on to the price, are multiplied by the amount of use of the mask, the more the mask is used, the more wasteful expenditure is increased.

FIG. 4 is a perspective view showing a structure according to a first embodiment of the present invention and [Claim 1]. First, one strap 2-2 ″ -2 ′ is passed through the hole of the stopper 4 having two holes that merge with each other inside, and the stopper 4 is moved along the strap 2-2 ″ -2 ′ so that the strap 2 It fixed when it came to the position of the same distance from both ends of -2 "-2 '.

Next, the end of the strap 2-2 ″ -2 ′ opposite to the stopper 4, that is, the inner space of the hollow sliding device 5 by bundling the two tips of the straps 2 and 2 ′ in FIG. 4. In addition, another intermediate hole that reaches the large hole from the side surface of the sliding device 5 and intersects vertically is provided, and a button 3 is embedded therein (FIG. 4). When the button 3 is pushed into the large hole, the coil spring 9 is pressed against the wall surface of the large hole to repel and push the button 3 back (FIG. 4).

Further, a small hole is made to penetrate the side surface of the button 3, and the two end portions of the strap 2-2 ″ -2 ′ passing through the large hole described in [0011] are also inserted into the small hole in the large hole. Note that when the button 3 was pushed deeply into the middle hole, the small hole was positioned at the center of the large hole, while the button 3 was pushed back by the repulsion of the coil spring 9. In this state, since the small hole comes out of the large hole, the strap 2-2 ″ -2 ′ smoothly slid inside the small hole and the large hole when the button 3 was pushed deeply. On the other hand, when the button 3 is pushed back by the repulsion of the coil spring 9, the position of the small hole tends to come out of the large hole, so that the strap 2 "is pressed against the wall surface of the large hole and the sliding is controlled. And fixed to the sliding device 5.

Next, as shown in FIG. 4, the fastener (male) 6 is attached to one end of the two string-like portions out of the sliding device 5 of the strap 2-2 ″ -2 ′, and the other end is attached to the other end. A fastener (female) 7 was fixed, a convex projection 10 was provided at the tip of the fastener (male) 6, and a concave hole 11 was provided inside the fastener (female) 7. An entrance of the hole 11 Although the inner diameter of the projection 10 is smaller than the outer diameter of the projection 10, an elastic body is used at the inlet, and a space for accommodating the projection 10 is provided in the deep portion of the hole 11. In addition, the fastener (male) 6 and the fastener (female) 7 fixed as described above were separated by separating them with an appropriate hand force.

If the sliding device 5 is held with one hand in the state of the above structure and the button 3 is pushed with its finger and the stopper 4 is grasped and pulled, the strap 2-2 "-2 fixed to the stopper 4 is pulled. 'Slid out and pulled out to the stopper 4 side, and at the same time, the portion of the strap 2-2 "-2' on the side of the fastener (male) 6 or the fastener (female) 7 was shortened. FIG. 2 shows a state before the stopper 4 is pulled, and FIG. 1 shows a state after the pulling (the finger is not shown in both figures), both of which are front views as seen from the back of the user. In any of the figures, the fastener (male) 6 and the fastener (female) 7 are respectively engaged with the left and right ear straps 1 and 1 'in a chain shape, and then connected and fixed to each other by the strap 2-2'. The state which formed the ring | wheel is shown. As shown in FIG. 1, when the stopper 4 is pulled, the size of the ring decreases, and at the same time, the left and right ear straps 1 and 1 ′ engaged with the straps 2 and 2 ′ are directed toward the sliding device 5. I was attracted. FIG. 3 shows the aspect as seen from the left side of the mask wearer, and shows how the tension of the ear straps 1 and 1 ′ increases and the degree of adhesion between the mask 8 and the face increases.

In order to weaken the tension of the ear straps 1 and 1 ′ and return to the state of FIG. 2, the sliding device 5 may be pulled downward while the button 3 is pushed. Since the sliding device 5 slides between the strap 2-2 "-2 'and becomes cheaper by pushing the button 3, it is easily lowered and formed by the strap 2-2' [0014] And the tension of the ear straps 1 and 1 'weakened, and the state of FIG. 2 was restored.

According to this method, the strength of the tension of the ear straps 1 and 1 'is adjusted simultaneously and evenly by the operation of the single sliding device 5, so that it is not necessary to adjust the left and right tension balance, and the mask Eliminates the difficulty of repeatedly attaching and detaching. This is the end of the description of the first embodiment.

Next, as another technical aspect of the sliding device according to the second embodiment of the present invention and according to [Claim 1], the button 3, the coil spring 9 and [0011] from the sliding device 5 of FIG. The inside hole described above is removed and the diameter of the internal space of the large hole described in [0011] is narrowed to slide with the strap 2-2 ″ -2 ′. As a technical aspect of claim 2], the male and female structures for connecting the fasteners (male) 6 and the fasteners (female) 7 of the first embodiment to the second embodiment such as the protrusions 10 and the holes 11 are mutually connected. Instead of the hook-shaped fasteners 12 and 12 ′ having the same shape, the left and right ear straps 1 and 1 ′ are used by being locked or fixed, respectively. 5 is provided with the features of the second embodiment and the third embodiment at the same time. It shows an aspect of the interleaf.

Finally, as a supplement, it is noted that in all the drawings attached to the present specification, illustration of human fingers is omitted for convenience.
