By fixing the dust protector 4 to the rim 21 of the frame 2 with a simple operation can do. In addition, if you apply a force in the opposite direction to when inserting the dust protector 4, It can be removed from Lame 2.   In addition, the frame 2 has a rear surface of the rim 21 when the dust protector 4 is not attached. Is it no different from ordinary glasses except that the engaging holes 24 are formed in the surface? In addition, it can be used as normal glasses without attaching the dust protector 4. Ie , A user using eyeglasses for vision correction has a frame 2 and a lens 3 for vision correction. If you put on, you can use the frame 2 instead of the glasses you were using it can.   In this way, the dust-proof eyeglasses 1 can be used as normal eyeglasses in normal times, and if necessary, In this way, it exerts a function to prevent invasion of pollen.

[0044]   As described above, the dust-proof glasses 1 according to the embodiment of the present invention can be easily operated. If you do not need a function to prevent pollen and dust because the dust protector 4 can be attached and removed. For removing the dust protector 4, the frame 2 is used as ordinary glasses. It becomes possible. That is, by attaching and detaching the dust protector 4 as necessary, pollen and powder Since a function to prevent dust can be obtained, high convenience can be realized. Especially the back of the rim 21 The frame 2 is almost the same as the frame of ordinary eyeglasses except that the engaging hole 24 is provided on the frame 2. It has a similar configuration. Therefore, if the dust protector 4 is removed from the dust-proof eyeglasses 1, normal eyes can be removed. It can be used just like a mirror.   Further, the structure in which the dust protector 4 is attached to the frame 2 is more convenient than conventional protective glasses. There is no discomfort in appearance, and the user's resistance can be significantly reduced.

[0045]   In addition, a cylindrical dust cover 4 extending from the back surface of the lens 3 toward the user's face. 1 closes the space between the lens 3 and the user's face and surrounds the user's eyes Can be reliably covered. This prevents pollen and dust from entering the eyes of the user. As such, it is possible to reliably protect the eyes of the user. In addition, the dust cover 41 includes When the user wears the dust-proof spectacles 1, the ventilation part 42 is arranged at a position that becomes the upper surface and the lower surface. Therefore, even if the space between the lens 3 and the user's face is tightly closed, Air can be efficiently circulated inside and outside this space. Therefore, the user's The lens 3 becomes cloudy due to moisture evaporating from the face and the temperature difference between the inside of the lens and the outside air. The user's visual field can be kept good and a comfortable feeling can be realized.

[0046]   Further, the fixing frame 43 is made of a rigid material, and the dust cover 41 is soft. Since it is made of a soft material, the dust-proof cover 41 is closely attached to the user's face. By contacting it, you can more reliably prevent pollen and dust, and Since the applied pressure can be reduced, the usability can be improved.

[0047]   In addition, in the above-described embodiment, a method of fixing the fixing frame 43 to the rim 21 The configuration using the engaging hole 24 and the engaging protrusion 44 has been described above.

The plurality of hook-shaped engaging projections 47 are adjacent to each other. The tips of the hook-shaped engaging projections 47 are arranged so as to face opposite directions. That The hook-shaped engaging hole capable of accommodating the hook-shaped engaging protrusion 47 is formed on the back surface of the rim 21. A plurality of 26 are drilled. The hook-shaped engaging hole 26 is a hook whose innermost portion is bent at a substantially right angle. Holes, and the hook-shaped engagement holes 26 adjacent to each other are drilled so that the innermost portions of the hook-shaped engagement holes 26 face in opposite directions. It is set up. The hook-shaped engagement hole 26 allows the hook-shaped engagement protrusion 47 to be easily fitted. It has openings and depths that are possible. Moved to   Therefore, when a force sufficient to elastically deform the hook-shaped engaging hole 26 is applied, the hook-shaped mating protrusion It is possible to fit 47 into the hook-shaped engagement hole 26 or pull it out. For this reason The rim 21 and the fixing frame 43 can be attached and detached only when a predetermined force or more is applied, It can be fixed so that it will not fall off during normal use.

[0052]   Further, in the above embodiment. Frame 2 is a full-rim type eyeglass frame However, the present invention is not limited to this, and is shown in FIG. 10, for example. As described above, the half-rim type frame 5 can be used instead of the frame 2. is there. The half-rim type eyeglass frame is also called the Nyroll type, which is almost above the lens. The rim is provided only in the part related to the half, and the lower half of the lens is It is a frame that is hung and supported by a frame.

[0053]   In the half-rim type frame 5 shown in FIG. 10, the rim 51 has an engaging hole 24 and A plurality of engaging holes 54 having the same shape are formed.   FIG. 11 shows the rear side of the rim 51 in the half-rim type frame 5 shown in FIG. It is a figure which shows a structure. As shown in FIG. 11, the rim 51 of the half-rim type frame 5 Three engaging holes 54 are formed on the back surface of each.   In addition, as shown in FIG. 12, in the dust protector 4 (FIG. 6), the fixing frame 43 is removed. The same number of engagement protrusions 44 as the engagement holes 54 are provided only in the portion that abuts the chamber 51, and 6 In the dust protector 6, the fixing frame 43 is shaped to fit the peripheral edge of the lens 3. It is in a state.

[0054]   In this case, the dust protector 6 has a smaller number of engaging protrusions 44 than the dust protector 4 and is used as the rim. The dustproof device 4 is made of, for example, the same material as that of the fixing frame 43. The weight can be easily reduced by adding synthetic resin.
