The present disclosure is related to combined reading glasses and sunglasses.
There are bifocal glasses, including sunglass lenses, having a reading glass lens at the bottom of the rim, and sun glass lenses, optionally with lens power at the upper part of the rim. However, glasses of this type have the disadvantage that the user does not obtain clear vision when the user is moving downward in steep terrain or in stairs, since the reading glasses are adapted to focus upon objects located close to the eyes.
JP H07159733 describes bifocal glasses where embodiments are formed symmetrically about an axis extending between the sidebars. In one embodiment, the ear connectors are arranged pivotal about the accompanying side bar.
US 2014/0354939 describes glasses having a case attached to the rear part of the side bars, serving as a place holder for personal belongings, such as credit cards and keys.
The inventive embodiments provide combined reading glasses and sunglasses, which also can be used when walking downward steep terrain or in stairs, without having to take off the glasses. The embodiments provide a single pair of glasses, which can replace two pairs of glasses, and which allow a wearer to read text on for example smartphones. The embodiments also provide glasses of this type that can be used for storing personal belongings, for example when swimming.
The aforementioned functions and advantages over known devices are provided by the disclosed embodiments of glasses which include substantially symmetrical bifocal sunglasses that can be turned upside down between a sunglasses mode and a reading glasses mode, said glasses comprising:
a spectacle frame having a first lens rim and a second lens rim, mutually connected by a bridge having a first side and a second side, wherein
a sunglass lens is arranged at a first area of and inside the respective lens rim, and
a reading glass lens is arranged at a second area inside of and inside the respective first and second lens rim, opposite and adjacent to said first area, thus forming an interface there between,
wherein a first and second side bar are connected pivotal to the first and second lens rim, respectively, said glasses being formed substantially symmetrically about an axis extending between the first and second side bar, wherein
a distance d between the first side of the bridge and the interface is preferably within an approximate range from about 7 mm to about 9 mm,
a thickness t between the top side and the underside of the bridge is preferably within an approximate range from about 3 mm to about 5 mm, and
wherein the bridge is provided with a first pair of bridge projections, arranged at the first side of the bridge, and a second pair of bridge projections, arranged at the second side of the bridge. The bridge projections serve as nose support to stabilize the glasses during use.
The distance d between the first side of the bridge and the interface is preferably about 8 mm, whereas the thickness t is preferably about 4 mm.
The end of the first and second side bar located most distant from the lenses are preferably provided with substantially symmetrical side bar projections extending a distance away from the side bar in a direction perpendicular to said axis. The side bar projections serve as stop and support means toward the ears of the person to further stabilize the glasses during use.
The invention is in the following described in further details by means of drawings, where
Among the benefits and improvements disclosed herein, other objects and advantages of the disclosed embodiments will become apparent from the following wherein like numerals represent like parts throughout the several figures. Detailed embodiments of combined reading glasses and sunglasses are disclosed; however, it is to be understood that the disclosed embodiments are merely illustrative of the invention that may be embodied in various forms. In addition, each of the examples given in connection with the various embodiments of the invention which are intended to be illustrative, and not restrictive.
Throughout the specification and claims, the following terms take the meanings explicitly associated herein, unless the context clearly dictates otherwise. The phrase “in some embodiments” as used herein does not necessarily refer to the same embodiment(s), though it may. The phrases “in another embodiment” and “in some other embodiments” as used herein do not necessarily refer to a different embodiment, although it may. Thus, as described below, various embodiments may be readily combined, without departing from the scope or spirit of the invention.
In addition, as used herein, the term “or” is an inclusive “or” operator, and is equivalent to the term “and/or,” unless the context clearly dictates otherwise. The term “based on” is not exclusive and allows for being based on additional factors not described, unless the context clearly dictates otherwise. In addition, throughout the specification, the meaning of “a,” “an,” and “the” include plural references. The meaning of “in” includes “in” and “on.
Further, the terms “substantial,” “substantially,” “similar,” “similarly,” “analogous,” “analogously,” “approximate,” “approximately,” and any combination thereof mean that differences between compared features or characteristics is less than 25% of the respective values/magnitudes in which the compared features or characteristics are measured and/or defined.
Now referring to
A first and second side bar 12 and 13 are each connected pivotal to the first and second lens rim 17 and 18, respectively.
Now referring to
As is apparent from the above, the glasses in accordance with the invention alleviate motion down stairs or steep terrain. However, the glasses also replace the need for two separate pairs of glasses, a separate pair of reading glasses and a separate pair of sunglasses. It should be mentioned that the need for reading glasses has increased the latest years because of digitalization which involves increased use of for example smart phones. Elder workers will also benefit from the present invention, e.g. at work.
