Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a pair of apron glasses for removably attaching another lens or an apron such as a protector for light protection to the glasses.

[0002]

[Prior art]

 An example will be given of apron eyeglasses in which other lenses or protective equipment for light protection, body wear, etc. are detachably attached to the eyeglasses. FIG. 1 is a perspective view showing an example of conventional front eyeglasses. FIG. 2 is a rear view showing an example of the conventional apron of the apron. One example is spring-type front spectacles. The apron 2 is provided with a pair of fittings 3 that are fixed to the bridge portion 4 via hinges or the like, and both ends of the fitting 3 are engaged with the bridge of the eyeglass body 1 and the lower edge of the rim. Have claws. Spring-type front spectacles use the elasticity of the metal fittings as shown by the arrows in the figure to attach and detach the front garments. When mounting, first attach the locking claws on the upper end of the metal fitting 2 of the front lug 2 to the spectacle body. Hang it on the bridge of No. 1 and hang the locking claw at the lower end of the metal fitting 2 on the lower edge of the rim of the eyeglass body.

FIG. 3 is a perspective view showing an example of conventional front eyeglasses. FIG. 4 is a rear view showing an example of the apron of the conventional apron glasses. An example shows clip-type front glasses. The apron 6 is provided with a clip 7 for mounting which is fixed to the bridge portion 9 via a hinge or the like, and is further provided with a metal fitting 8 which is crimped around the nose pad of the eyeglass body 5. Clip-type apron glasses are designed such that the body of the spectacle is sandwiched between the metal fitting 8 and the apron and fixed with clips. The tip of the metal fitting 8 is attached to the tip of the metal fitting 8 so that the metal fitting 8 does not damage the lens of the spectacle body when attaching or detaching. A resin cap 10 is attached.

[0004] Conventionally, many apron glasses as described above have been seen, but in addition, in order to make them removable, magnet-attached ones have been devised. For example, in the fashion glasses for VDT work disclosed in Japanese Patent Laid-Open No. 61-57923, a second polarizing lens is attached to a first polarizing lens held at a position apart from the face by a magnet. In the visual display terminal device operating mechanism disclosed in Japanese Patent Laid-Open No. 61-114221, a rotatable polarizing filter and an ND filter that overlaps with the polarizing filter are mounted on a frame by magnetic attraction between magnets.

Japanese Patent Laid-Open No. 7-128620 discloses a detachable sunglasses using a magnet, in which a magnet and a magnet or a magnetic body are attached to a frame or sunglasses of another spectacle so that the sunglasses can be detached. The spectacles of Japanese Utility Model Laid-Open No. 57-184910 are equipped with magnets in addition to ordinary spectacles so that other protective spectacles can be attached and detached. The sunglasses mounting device disclosed in Japanese Utility Model Laid-Open No. 2-109325 is equipped with a magnet in a fixed portion provided on each of the eyeglasses and the sunglasses so that the sunglasses can be attached. The double lens goggles disclosed in Japanese Utility Model Laid-Open No. 5-70527 have a lens and a frame such as goggles provided with a magnet and a magnetic attachment member so that the lens member can be attached and detached.

[Problems to be solved by the device]

 However, as described above, in any of those attached by a magnet, if the area magnetized by the magnetic force is small, the magnetizing force is insufficient and a stable fixed state cannot be obtained. It is necessary to make the magnetized surface large in order to obtain a stable fixed state, but the appearance and cost are difficult and the weight is heavy, so the wearing feeling is poor. In addition, if the magnetic force due to the magnetic force is strong, there is a problem that it takes time to remove it, so it is not widely used.

Therefore, conventionally, spring-type or clip-type front spectacles, which are relatively easy to put on and take off, have been used. However, the spring-type front spectacles have large fasteners, and the structure for mounting the apron is insufficient in strength, so the apron is limited to a thin and lightweight material such as a protective gear for dimming. The clip type has a particularly large fastener, and the tip of the fastener needs to be covered with a resin cap or the like for protecting the lens, which is unsatisfactory. Again, the strength of wearing the apron tends to be insufficient, and it is difficult to use a heavy object such as a convex lens for the apron.

In addition, the conventional apron glasses have a special problem of wearing sunglasses and protecting eyesight because of problems such as time-consuming work for attaching and detaching the apron, easy access to the lens surface, and unfavorable aesthetics. It is only used for anti-glare and dimming glasses.

It is an object of the present invention to provide a pair of apron glasses that are aesthetically pleasing, can be stably fixed even if a heavy apron is used, and can be easily put on and taken off.

[0010]

[Means for Solving the Problems]

 In order to solve the above problems, the front spectacles of the present invention are provided with a U-shaped hook for locking the bridge of the spectacles body and a position stabilizing member for locking near the blow of the rim upper edge of the spectacles. It is composed of an apron having a hook and a main body of glasses. As a supplement, a magnet is provided on the bridge of the spectacles body, and a magnet is attached to the hook provided on the apron bridge that is combined with the magnet at a position where it abuts the magnet provided on the spectacles body, so that the apron is kept stable on the spectacles body. It is easy to hold and remove.

When a magnet is used for the front spectacles of the present invention, by using a strong magnet having a large magnetic attraction force and exhibiting magnetism in the direction of the magnetic attraction surface, it is sufficient to use a magnet only in the bridge portion. You can get strength. The apron glasses of the present invention can be used for sunglasses, special anti-glare glasses, bifocal glasses, and the like.
