Folding glasses

This invention relates to a folding glasses which is provided with a pair of lens covers adapted to be swung between a horizontal position for shading glare light and a dependent position for protecting lenses thereof, and is adapted to be folded into a decorative shape of a beetle or the like.

BACKGROUND OF THE INVENTION 
This invention relates to a glasses, and particularly to a folding glasses. 
Conventionally, a sunglasses comprises an eyecovering section or sun screen 
adapted to be swung optional into, or out of, the line of vision of the 
wearer as disclosed by U.S. Pat. No. 2,998,610. It is found inconvenient 
in bringing. Several types of folding glasses are available at the present 
time. Yet they work without decorative and lenses-protecting functions. To 
this end, the inventor has attempted to make an improved folding glasses 
to overcome the drawbacks of the known glasses. 
SUMMARY OF THE INVENTION 
An object of this invention is to provide a folding glasses which can 
diminish the disadvantages of the known glasses. 
It is another object of this invention to provide a folding glasses with a 
construction allowing the glasses to be folded in a shape with decorative 
function. 
It is yet another object of this invention to provide a folding glasses 
with a pair of lenses shaded by a pair of covers as in wearing condition 
and protected by the covers as in folded condition. 
With the above object in view, this invention provides a folding glasses 
which comprises a head engaging frame member having a pair of swingable 
spaced lenses joined by means of a bridge member and two temples having 
swingable terminal sections, being hingedly attached to the lenses, and a 
pair of lens covers hingedly attached to the lenses via a pair of 
supporting bracket units, and swingable between a first horizontal 
position for shading the lenses and a second dependent position for 
protecting the lenses.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
The following is a detailed description of the best presently contemplated 
embodiment of the invention. This description is not to be taken in a 
limiting sense, but is made merely for the purpose of illustrating the 
general principles of the invention. 
As shown in FIGS. 1, 2 and 3, broadly speaking, the folding glasses 
according to this invention comprises a head engaging frame member 8 
having a pair of spaced lenses 1, 2, a pair of lens covers 4, 6 preferably 
made of obscure material and printed with a plurality of circular patterns 
thereon, and being substantially corresponding in shapes to that of the 
lenses 1, 2, respectively and hingedly attached thereto via a pair of 
supporting bracket units 40, 50, and swingable between a first horizontal 
position for shading glare light wherein the lens covers 4, 5 are out of 
the line of vision of the wearer, and a second dependent position as to be 
folded. 
The frame member 8 comprises a bridge member generally indicated at 3 
including a frontal plate 32 and an opposed rear plate 33 which sandwiches 
the inner portions of the spaced lenses 1, 2 and at least two studs 30, 31 
spacedly penetrated through the stacked portions of the frontal plate 31, 
the lenses 1, 2 and the rear plate 33. The lenses thus joined are 
swingable between a wearing position, as shown in FIGS. 1, 2 and 3 and a 
folded position, as shown in FIGS. 4, 5 and 6, and a nose engaging member 
34 having a head portion attached to an inner side wall of the rear plate 
33 and two divergent arms 341, 342 extending downwardly outwardly with 
curved outer side walls engaged with portions of the bottom walls of the 
lenses 1, 2 located in the wearing position. 
Two temples 6, 7 having respective side bars 61, 71 of each of which the 
length is slightly shorter than half of the distance therebetween and 
swingable terminal sections 60, 70 designated to rest on the ears and grip 
the head of the wearer, are hingedly attached to outer portions of the 
lenses 1, 2 at hinges 62, 62. Furthermore, said side bars 61, 71 in 
conjunction with the folded terminal sections 60, 70 are swingable between 
a wearing position and a folded position behind the respective lenses 1, 
2, as shown in FIG. 3. 
Said terminal sections 60, 70 are hingedly attached to the respective far 
end portions of the side bars 61, 71 so as to be swingable between a 
wearing position and a folded position under the side bars 61, 71, as 
shown in FIG. 3. 
A well portion is formed in a mid upper edge of each of the lenses 1, 2 
wherein a substantially T-shaped projector is located on a mid portion of 
a flat bottom wall of the well portion defining a pair of spaced 
receptacles between the projector and side walls of the well portion. 
The supporting bracket units 40, 50 comprises two sets of connecting bodies 
with one end of each of which interally formed on a mid upper inner wall 
of each of the covers 4 or 5. A pair of opposed recesses are provided for 
respectively receiving trunnions of the T-shaped projector in opposed 
inner side walls, and a pair of aligned grooves or notches 401 or 501 are 
transversely provided on either set of the connecting bodies. The 
supporting bracket units 40, 50 are mounted on the lenses 1, 2 by fitting 
the trunnions of the T-shaped projectors 11, 21 into the recesses so that 
the lens covers 4, 5 are swingable between the first horizontal position 
wherein the grooves or the notches 401, 501 of the connecting bodies are 
engaged with the bottom walls of the well portions of the lenses 1, 2, and 
the second dependent position. 
A lock member is further provided for firmly maintaining the folding 
glasses in folded condition, as shown in FIGS. 1, 2 and 5, which comprises 
a pair of spaced posts 52, 53 integrally formed on an inner side wall of a 
lens and adapted to firmly receive a plug member 52 integrally formed on 
an inner side wall of the other lens as the lenses 1, 2 in conjunction 
with the covers are resided in the folded position. 
In folding operation, as shown in FIGS. 3 and 4, firstly, the temples 6, 7 
are swung into the folded position and the lens covers 4, 5 are swung into 
dependent position, then the lenses 1, 2 in conjunction with respective 
dependent covers 4, 5 are swung into the folded position in a shape 
similar to a beetle of the like, as shown in FIGS. 5 and 6. 
The preferred embodiment of this invention resides in the following 
features: 
(1) In normal usage, the lens covers 4, 5 are in the position shown in FIG. 
2 wherein the covers extend horizontally outwardly of the respective 
lenses 1, 2 with the covers out of the line of vision of the wearer for 
shading glare light; 
(2) In folded condition, the lenses 1, 2 are respectively under protection 
of the covers 4, 5 and the shape is decorative; and 
(3) The folding procedure is easy and simple in operation. 
While the invention has been described with what is presently considered to 
be the most practical and preferred embodiment, it is to be understood 
that the invention is not to be limited to the disclosed embodiment, but 
on the contrary, is intended to cover various modifications and equivalent 
arrangements included within the spirit and scope of the appended claims, 
which scope is to be accorded the broadest interpretation so as to 
encompass all such modifications and equivalent structure.
