  Next, an example of how to assemble goggles 1 will be described.

  First, as shown in FIGS. 7A and 7B, the lens body 12 constituting the lens member 11 is inserted into the groove 38 while the holding portion 37 of the frame member 31 is expanded vertically and horizontally. The locking groove 13 is made to face the locking protrusion 39, and the locked recess 14 is made to face the locking protrusion 40.

  Then, the holding portion 37 is pressed to the lens main body 12 side over the entire circumference, so that the locking projection 39 is engaged with the locked groove 13 and the locking protrusion 40 is engaged with the locked recess 14. When combined, as shown in FIG. 6A, the lens body 12 can be held by the holding portion 37 so as not to be easily detached.

  As described above, when the lens body 12 is held by the holding portion 37, the left and right side upper portions 12 LU and 12 RU and the left and right side lower portions 12 LD and 12 RD come into contact with the bottom of the groove 38 of the holding portion 37. 6 (b) and FIG. 7 (b), the left and right protruding portions 16L and 16R protrude from the holding portion 37 to the inside of the frame member 31 as shown in FIGS. 17L and the left insertion hole 35L overlap, and the right engagement hole 17R and the right insertion hole 35R overlap.

  In this way, with the left insertion hole 35L overlapped with the left engagement hole 17L and the right insertion hole 35R overlapped with the right engagement hole 17R, the locking portion 28b is made to correspond to the long axis direction of the long holes 35a and 17a. In addition, the left and right engagement portions 28L and 28R are made to correspond to the left and right insertion holes 35L and 35R, and the left and right engagement holes 17L and 17R with the shaft portion 28a corresponding to the round holes 35b and 17b. The members 26L and 26R are inserted until they contact the cylindrical portion 32.

  Thus, when the left and right engagement portions 28L and 28R are inserted into the left and right engagement holes 17L and 17R, a part of the left and right engagement members 26L and 26R is left and outside the right receiving recesses 36L and 36R. Since the left and right engaging members 26L and 26R are further pressed toward the frame member 31 side, the left and right engaging members 26L and 26R (or the frame member 31) are distorted (flexed). As a result, the locking portion 28b protrudes inside the left and right protruding portions 16L and 16R.

  In this state, the left engagement member 26L is rotated counterclockwise about the shaft portion 28a, and as shown in FIGS. 8A and 8B, the right engagement member 26R is By rotating clockwise around the shaft portion 28a, the left engaging member 26L and the locking portion 28b sandwich the left protruding portion 16L and the cylindrical portion 32, and the left engaging member 26L is accommodated on the left side. As shown in FIG. 6B, the right engaging member 26R and the locking portion 28b sandwich the right protruding portion 16R and the cylindrical portion 32, and the right engaging member 26R Since it enters the right accommodation recess 36R, it can be assembled in the state of FIG.

  In this state, even if the left and right engagement members 26L and 26R rotate about the shaft portion 28a, the left and right engagement members are engaged before the locking portions 28b overlap in the long axis direction of the long holes 35a and 17a. Since the members 26L and 26R abut against the peripheral wall 36a of the left and right receiving recesses 36, the mounting band 21 can be attached to the lens member 11 so as not to be easily detached.

  Then, the left and right engaging members 26L and 26R are rotated around the shaft portion 28a so that the left and right engaging members 26L and 26R are in contact with the peripheral wall 36a of the left and right receiving recesses 36. When the left and right engagement members 26L and 26R are further rotated with a strong force, the frame member 31 is distorted (flexed), so that the left and right engagement members 26L and 26R ride on the side surfaces of the frame member 31. Since the locking portions 28b overlap in the long axis direction of the long holes 35a and 17a, the left and right engaging members 26L and 26R can be easily detached from the lens member 11.

  After operating the length adjusting member 24 of the goggles 1 assembled as described above to adjust the mounting force of the band main body 22 (band main body 23) (the entire length of the band main body 22), the contact portion 42 is moved to the face. The goggles 1 can be attached by bringing the band main body portion 22 along the back of the head while making the contact around the eyes and the slit 43 corresponding to the nose.

When the goggles 1 are worn, the eyes and around the eyes (portions excluding the nose) of the wearer's face are covered with the lens body 12 and the frame member 31.
Then, the lens member 11 is pulled rearward by the mounting band 21 along the wearer's head, so that the left and right side upper side portions 12LU and 12RU and the left and right side lower side portions of the lens body 12 12LD and 12RD press the frame member 31 (holding portion 37) to the rear side, and the curved surface portion of the lens body 12 presses the frame member 31 (holding portion 37) to the rear side, and the frame member 31 (contact portion 42). ) Adheres closely to the wearer's face.

As described above, according to one embodiment of the present invention, the goggle 1 is configured by the lens member 11, the band (band main body 23), the left and right engaging members 26L and 26R, and the frame member 31. In other words, since the goggles 1 can be configured with five parts, which is two parts fewer than the third goggles of the conventional example, the goggles 1 can be manufactured at a low cost and the assembly of the goggles 1 is facilitated. It can be carried out.
Further, since the left and right engaging members 26L and 26R are engaged with the rigid lens member 11 instead of the frame member 31 made of an elastically deformable material, the frame member 31 is hardly damaged. .

Further, since the left and right engagement members 26L and 26R are detachably engaged with the lens member 11, the band can be easily exchanged (detached).
Further, even when the left and right engaging members 26L and 26R rotate around the shaft portion 28a with the band member 21 attached to the lens member 11, the long holes 35a and 17a are locked in the long axis direction. Since the left and right engaging members 26L and 26R abut against the peripheral wall 36a of the left and right receiving recess 36 before the portion 28b overlaps, the mounting band 21 is detachably attached to the lens member 11 so as not to be easily detached. Can do.

In addition, when the goggles 1 are mounted, the mounting band 21 pulls the lens member 11 to the rear side in a balanced manner at the left and right ends, so that the frame member 31 is also pushed back in a balanced manner. Since the face is pressed with a substantially uniform pressure in a balanced manner, the wearer can wear the goggles 1 in a stable state without discomfort.
In addition, left and right engagement holes 17L and 17R are provided in the left and right protrusions 16L and 16R of the lens member 11, and left and right engagement members 26L and 26R are provided in the attachment band 21, and the attachment band 21 is attached to the lens member 11. Since the left and right protrusions 16L and 16R of the lens member 11 are positioned inside the frame member 31, the portion exposed to the outside of the frame member 31 is reduced and the design is improved. The lens member 11 is engaged with the left and right projecting portions 16L and 16R even when the lens member 11 is detached from the holding portion 37, so that the lens member 11 and the frame are improved. The member 31 does not fall apart.

Further, with the goggle 1 attached, the left side upper part 12LU and the left side lower part 12LD press the left end (holding part 37) of the frame member 31 against the face of the wearer, and the right side upper part Since the portion 12RU and the right side lower portion 12RD press the right end portion (holding portion 37) of the frame member 31 to the wearer's face, the frame member 31 is pressed against the wearer's face in a balanced manner. Is added, and a good wearing feeling can be obtained.
Further, since the left and right receiving recesses 44L and 44R are provided in the frame member 31, when the goggles 1 are attached, the temples of the glasses are not pushed to the side of the head, and the wearing feeling can be improved.
