Pass the ear straps of the mask through the guide and hold the ear straps. According to this invention, it is possible to solve the problem that occurs when the ear straps are hooked on the ears, but for example, even if the length of the ear straps changes after changing the mask, the mask cannot be worn on the face. It doesn't mean you can make it fit.

Furthermore, the mask holder described in Utility Model Registration No. 3136570 (Patent Document 2) allows the ear straps of the mask to be attached to the temples of glasses by using the locking member. In this invention, since the temples of the glasses and the ear straps are integrated, it is possible to solve the problem that occurs when the ear straps are hooked on the ears, but there is also the problem that it takes time and effort to attach the ear straps to the temples. be. Another problem is that the position of the ear string at the temple is not necessarily fixed.

The details of the ear strap hook for a mask according to the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a diagram showing a mask ear strap hanger 10 (hereinafter referred to as the hanger 10) in use, and also shows the head of a wearer 1 wearing glasses 20 and a mask 30. . In FIG. 1, the direction that connects the face 2 and the back of the head 3 of the wearer 1 is the front-back direction A, the direction that connects the left and right ears 4 is the lateral direction B, and the direction that connects the neck 5 and the top of the head 6. The direction is the vertical direction C. The glasses 20 include a pair of left and right lens parts 21 and a pair of left and right temples 22. The temple 22 is a portion also called a "vine." The pair of temples 22 can be folded over each other, but in the figure, the temples 22 extend parallel to each other in the front-rear direction A, and the portions near the ears 4 are provided with a hook. 10 is attached. The temple 22 is also formed with at least one hole (female thread) 23 for attaching the hanger 10 and extending in the lateral direction B. The mask 30 has a face covering part 31 that functions as a filter, and a pair of left and right ear straps 32. The ear strap 32 has upper and lower end portions 33a and 33b attached to the face covering portion 31, extends in an arc toward the rear in the front-rear direction A, and has a rear end portion 34 that is attached to the hanger 10. It's being passed around. In the ear strap 32, the part extending from the upper end 33a to the hanger 10 is called an upper part 32a, and the part extending from the lower end 33b to the hanger 10 is called a lower part 32b.

FIG. 2 is a diagram showing the left side of the head 7 of the wearer 1 in FIG. 1, in addition to the hanger 10 in FIG. The tool 10 and the ear strap 32 are shown in phantom lines.

As is clear from FIGS. 1 and 2, when the wearer 1 of the glasses 20 to which the hanger 10 is attached wears the mask 30, the ear strap 32 is attached to the hanger 10 rather than to the ear 4. It can be passed around. In addition, the hook 10 is attached to a position on the temple 22 according to the length of the ear strap 32, in other words, so that the ear strap 32 is in an appropriate tension state when trying to wear the mask 30. The hole 23 can be selected. In the illustrated example, the hole 23 is female threaded.

FIG. 3 is a top view and a partially enlarged view of the eyeglasses 20, in which the hooks 10 are attached to each of the temples 22 of the eyeglasses 20. The hanger 10 has a main body 15 including a small diameter part 11 and a large diameter part 12, and the main body 15 is fixed so that the end surface 11a of the small diameter part 11 can be attached to the temple from the outside in the lateral direction B. It is attached to the temple 22 in a state where it is in contact with the outer surface 22b of the temple 22. There is a clearance CL between the end surface 14 of the small diameter portion 11 and the outer surface 22b of the temple 22. Using the clearance CL, the ear strap 32 is hung around the small diameter portion 11 of the hanger 10 (see the partially enlarged view of FIG. 3). The large diameter portion 12, which is larger than the small diameter portion 11, prevents the ear strap 32 from coming off the small diameter portion 11.

FIG. 4 is a sectional view taken along the line IV-IV in the partially enlarged view of FIG. 3, and (a) to (c) illustrate a method of attaching the hanger 10 to the temple 22. There are various examples of how to attach the hanger 10, and in FIG. A hanger 10 is attached to the outer surface 22b of the temple 22. In FIG. 4(b), the hanger 10 is attached to the temple 22 by screwing the male screw 44 inserted into the through hole 43 formed in the hanger 10 into the female screw 23a of the temple 22. In FIG. 4(c), the hanger 10 is attached to the temple 22 by inserting the countersunk screw 42 into the hole 23 from the inner surface 22a side of the temple 22 and screwing it into the screw hole 45 of the hanger 10. . In the hanger 10, the male threaded portion 41, flat head screw 42, and male thread 44 are fixing means for fixing the main body 15 to the temple 22.

FIG. 5 is a diagram similar to FIG. 4(a) showing one aspect of the hanger 10 attached to the temple 22. However, in FIG. 5, the sleeve 13 exists on the outside of the small diameter portion 11 in the hanger 10 in the radial direction. Furthermore, a flat washer 46 is present between the sleeve 13 and the outer surface 22b of the temple 22. The sleeve 13 freely rotates around the small diameter portion 11. The flat washer 46 is used when there is a possibility that the sleeve 13 will contact the outer surface 22b of the temple 22 and be prevented from rotating. If there is no such possibility, the invention can be practiced without the flat washer 46. In the hanger 10 having the structure illustrated in FIG. 5, the rear end portion 34 (see FIG. 1) of the ear strap 32 can smoothly move together with the flat washer 46 in the circumferential direction of the small diameter portion 11 of the hanger 10. It is easier to keep the upper portion 32a and lower portion 32b (see FIG. 1) of the ear strap 32 under similar tension. The sleeve 13 can also be employed in the hanger 10 illustrated in FIGS. 4(b) and 4(c).

FIG. 6 is also a diagram similar to FIG. 4(a) showing one aspect of the hanger 10 attached to the temple 22. However, a plurality of irregularities 47 are formed on the circumferential surface of the small diameter portion 11 in the hanger 10 of FIG. 6 in order to make the circumferential surface rough. An example of the unevenness 47 is one obtained by knurling the peripheral surface. The unevenness 47 is adopted to reduce the slippage of the ear string 32 on the circumferential surface of the small diameter portion 11. By using the hanger 10 having such unevenness 47, the upper part of the ear string 32 It becomes easy to differentiate the tension states between 32a and the lower portion 32b. For example, in the ear strap 32, the tension state of the upper part 32a is made high to bring the upper part 31a (see FIG. 2) of the face covering part 31 of the mask 30 into close contact with the area around the nose of the wearer 1, while the lower part It becomes possible to create a state in which the lower part 31b (see FIG. 2) of the face covering part 31 is weakly brought into close contact with the chin of the wearer 1 by lowering the tension state of the face covering part 32b. Moreover, on the contrary, it is also possible to lower the tension state of the upper part 32a of the ear strap 32 while increasing the tension state of the lower part 32b. By adjusting the face-close state of the mask 30 in this manner, the mask wearer 1 can increase or decrease the amount of intake air and exhaust air passing between the upper portion 32a and the face. The same applies between the lower portion 32b and the face. The reason why the tension state of the ear strap 32 can be adjusted in this manner is that the ear strap 32 is difficult to slip on the small diameter portion 11 of the hanger 10 having the unevenness 47.

7 and 8, FIG. 7 is a view similar to FIG. 1 showing an example of the embodiment, and FIG. 8 is a view taken along the line VIII-VIII in FIG. For the glasses 20 and mask 30 in FIG. 7, a hanger 10 equipped with a male screw 49 that is operated from below in the vertical direction C is used. The hanger 10 has the structure shown in FIG. 8, and the large diameter part 12 has the same external shape as that in FIG. 4, but the shape of the small diameter part 11 is different from that in FIG. 11a, a lower wall 11b, and a groove 11c that is formed between these walls 11a, 11b and extends in the front-rear direction A. The groove portion 11c is a portion of the glasses 20 that accommodates a portion of the temple 2 in the length direction, and when viewed in the lateral direction B, a bottom portion 11d is formed on the large diameter portion 12 side, and an opening 11e is formed on the temple 22 side. is formed so that the temple 22 can be accommodated as shown in the illustrated example. The male screw 47 passes through a screw hole 48 formed in the lower wall 11b and extends to the temple 22. When the male screw 49 is operated from below the lower wall 11b, the temple 22 is held between the male screw 49 and the upper wall 11a in the groove 11c, and the hanger 10 can be fixed to an arbitrary position on the temple 22. The male screw 49 is an example of a fixing means in the hanger 10. In the temple 22 when using the hanger 10 in this manner, the hole 23 (see FIG. 1) for fixing the hanger 10 is not required. The small diameter portion 11 in this example is called a small diameter portion because the dimension in the vertical direction C is smaller than the dimension of the large diameter portion 12.

FIG. 9 is a diagram showing the front surface 12a of the large diameter portion 12 of the hanger 10, and (a) to (d) illustrate patterns applied to the front surface 12a. The front surface 12a may be a flat and plain portion, but it can be decorated according to the preference of the wearer of the mask 30 who is also the wearer of the glasses 20. For example, as shown in the illustrated example, the front surface 12a may be provided with an appropriate pattern, some materials may be changed, or it may be colored. The designs include not only flat designs but also three-dimensional ones. If the hanger 10 is made more conspicuous by such decoration, it will not only be easier to distinguish one's own hanger 10 from those of others, but also prevent the user from misplacing the glasses 20 to which the hanger 10 is attached. It can also be expected to prevent serious problems.
