1. Field of the Invention
The present invention relates to eyeglasses, and more particularly, to eyeglasses with movable lenses.
2. Description of the Related Art
As a person ages, eyesight often deteriorates. Eyeglasses can be used to correct for the deterioration. But more than one prescription can be required to correct for different problems. For example, a person may need correction for distance vision as well as needing correction for close-up work, such as reading. Bifocals are a common solution to such a problem. But many people get dizzy and/or sick using bifocals. Further, when working on a computer, bifocal users often have to hold their heads at odd or uncomfortable angles. And although some people adjust and are able to use bifocals without issue, some people do not adjust, or do not want to adjust.
For such people, one solution is to have multiple pairs of glasses, for example, a pair of reading glasses and a pair of distance-vision glasses. But carrying more than one pair of glasses can be cumbersome, and glasses can be misplaced if not worn. The problem is exacerbated if sunglasses are also used. Accordingly, improvements are needed.
Accordingly, it is an aspect of the present invention to provide wearable eyeglasses with more than one pair of separate viewing lenses.
The foregoing and/or other aspects of the present invention are achieved by providing eyeglasses, including a frame for supporting the eyeglasses on a user's face, a platform movably connected to the frame, and a plurality of lenses moveable relative to the frame along with the platform, each of the lenses being movably connected to the platform.
The foregoing and/or other aspects of the present invention are achieved by providing a method of changing lenses to see through on eyeglasses, including moving a first lens out of a viewing position on a frame of the eyeglasses, and moving a platform relative to the frame, thereby positioning a second lens to be moved into the viewing position. The first and second lenses are movably connected to the platform, and the platform is movably connected to the frame. The method also includes moving the second lens into the viewing position.
Additional and/or other aspects and advantages of the present invention will be set forth in the description that follows, or will be apparent from the description, or may be learned by practice of the invention.
The above and/or other aspects and advantages of embodiments of the invention will be more readily appreciated from the following detailed description, taken in conjunction with the accompanying drawings, of which:
Reference will now be made in detail to embodiments of the present invention, which are illustrated in the accompanying drawings, wherein like reference numerals refer to like elements throughout. The embodiments described herein exemplify, but do not limit, the present invention by referring to the drawings. As will be understood by one skilled in the art, terms such as up, down, upper, lower, bottom, and top are relative, and are employed to aid illustration, but are not limiting.
More specifically, according to one embodiment, the platform 108 is rotatably connected to the frame 102. For example, a pin can be connected to the frame 102, and the platform 108 can be rotatably secured to the pin so that the platform 108 can rotate about the pin relative to the frame 102. In other words, the platform 108 rotates about a first or platform axis relative to the frame 102. According to one embodiment, the first axis is substantially perpendicular to a side of the frame 102. According to another embodiment, the platform axis is substantially perpendicular to the extension support 104 (when the extension support is in an extended position). In other words, the platform axis is substantially parallel to a face of the frame (if the frame is substantially planar). One skilled in the art will appreciate that the angles of axes relative to other portions of the eyeglasses 100 can vary without departing from the present invention's scope. One skilled in the art will also appreciate that other mechanisms can be employed to movably connect the platform 108 and the frame 102 without departing from the present invention's scope.
The first and second lenses 106 and 110 are movably connected to the platform 108. Because the lenses 106 and 110 are connected to the platform 108, as the platform 108 moves (for example, rotates) relative to the frame 102, the first and second lenses 106 and 110 also move relative to the frame 102 along with the platform 108. The combination of the platform 108 and the first and second lenses 106 and 116 forms a lens set. Preferably, a lens set is movably connected to the frame 102 for each eye, as shown in
Preferably, the first and second lenses 106 and 110 are rotatably connected to the platform 108. In more detail, according to one embodiment, the first lens 106 is rotatably connected to the platform 108. Put another way, the first lens 106 rotates about a first lens axis with respect to the platform 108. Similarly, the second lens 110 is rotatably connected to the platform 108. Stated differently, the second lens 110 rotates about a second lens axis with respect to the platform 108. According to one embodiment, the first lens axis and the second lens axis are not co-linear. Although according to one embodiment, the first lens axis and the second lens axis are substantially parallel. According to one embodiment, each of the first and second lenses 106 and 110 are movable relative to the platform 108 independent of each other.
As illustrated in
In
To change from the first lens 106 to the second lens 110, the user first rotates the first lens 106 away from the viewing position to an open position, as shown in
In addition to, or as an alternative to the stopped rotation, the first and second lenses can have a positioning and/or securing unit. According to one embodiment, either the frame 102 or the lenses 106 and 110 have a lug, and the other of the frame 102 and the lenses 106 and 110 has a receiving slot or hole to receive the lug. For example, the frame 102 can have a lug and the first and second lenses 106 and 110 can each have a receiving slot or hole. When positioning the lens in the viewing position, the lug engages the receiving slot to properly position the selected lens relative to the frame 102, and also to help prevent the lens from unintentionally moving out of the viewing position. Such a system can also be employed to secure the unselected lens to the ear extension support 104.
Alternatively, both the lenses 106 and 110 and the frame 102 can have corresponding magnets disposed therein to properly position the selected lens relative to the frame 102, and also to help prevent the lens from unintentionally moving out of the viewing position. Such a system can also be employed to secure the unselected lens to the ear extension support 104. One skilled in the art will appreciate that other methods or mechanisms can be employed without departing from the scope of the present invention.
Subsequent to moving the first lens 106 to the open position, the user begins to rotate the lens set relative to the frame 102, as shown in
As shown in
To change from second lens 110 back to the first lens 106, the user reverses the process. According to one embodiment, the platform 108 can rotate in either direction relative to the frame 102.
Preferably, the third lens 112 is rotatably connected to the platform 108. More preferably, the third lens has two axes of rotation 114 and 116 (best shown in
Although only a few embodiments of the present invention have been shown and described, the present invention is not limited to the described embodiments. Instead, it will be appreciated by those skilled in the art that changes may be made to these embodiments without departing from the principles and spirit of the invention. It is particularly noted that those skilled in the art can readily combine the various technical aspects of the various elements of the various exemplary embodiments that have been described above in numerous other ways, all of which are considered to be within the scope of the invention, which is defined by the appended claims and their equivalents.
