Abstract
Description
- The present application claims the benefit and priority of U.S. Provisional patent application 60/181,337 filed Feb. 9, 2000 and entitled “Lens Locking Device”, the disclosure of which is incorporated by reference in its entirety herein.
- The present invention relates to eyewear and in particular to a lens locking device for eyewear.
- Various forms of eyewear are well known. The prior art fails to provide a simple technique for locking removable lenses in position on an eyewear frame so that lenses can be conveniently changed. Further, the prior art does not provide a simple technique for locking a lens of eyewear in position using a minimal number of attachment points and so as to avoid distortion of the lens.
- The prior art fails to provide a convenient and simple means for allowing a wearer of eyewear to select among various lenses for use with the eyewear, which holds the lens in position conveniently and allows the lens to be affixed in a simple manner.
- U.S. Pat. No. 5,703,669 to Park shows a lens locked in position between a bridge bar and a nose support of the eyewear. However, the lens is located in a long channel which extends for substantially the entire length of the bridge bar. This creates difficulties in fastening the lens and in manufacturing.
- U.S. Pat. No. 4,632,526 to Lhospice shows a single attachment of the lens from above the nose support portion at the bridge bar. However, in this design the nose support portion itself is attached to the lens unit, making the lens unit itself more complex and thus interfering with easy interchangeability of lenses.
- U.S. Pat. No. 5,026,150 to Weber shows spectacles which attach above the nose support portion to the bridge bar and also to lower portions of the frame at a plurality of locations. Accordingly, this reference discloses a device which is complex and interferes with easy lens attachment and interchangeability.
- U.S. Pat. No. 5,428,410 to Lei shows a lens which is received in a channel similar to the Park reference and the nose piece is also attached to the lens, thus suffering from the same disadvantages as the references discussed above.
- Other references include the following Lin U.S. Pat. Nos. 5,321,444, Lin 5,903,331, Jannard 4,674,851, Lin 4,951,322, Conway 5,467,148, Maturapom 5,796,460 and Conway 5,777,714.
- None of the prior art, however, shows a simple arrangement for providing a quick and convenient way for attaching an eyewear lens to a frame of the eyewear and which also facilitates interchangeability and removability of lenses that attach to the eyewear.
- Accordingly, it is an object of the present invention to provide a lens locking device which allows a lens to be easily, conveniently and removably attached to a frame of eyewear.
- Further, it is an object of the present invention to facilitate the attachment of various interchangeable lenses to eyewear in a simple fashion.
- The above and other objects of the present invention are achieved by a device for holding a lens of eyewear to an eyewear frame comprising: a first fastening portion disposed at approximately a mid point of a bridge bar of the eyewear frame and being disposed only near the midpoint, the first fastening portion having an attachment point for removably fastening the lens, a second fastening portion for removably fastening the lens disposed opposite the first fastening portion and being formed on a nose support of the eyewear, whereby a lens can be removably attached to the first and second fastening portions to removably secure the lens to the eyewear, there being no other attachment point for the lens to the eyewear frame.
- The objects of the invention are also achieved by an eyewear frame comprising a bridge bar and two temple portions; the bridge bar having a first fastening portion disposed at approximately a midpoint of the bridge bar and being disposed only near the midpoint, the first fastening portion having an attachment point for removably fastening the lens, a nose support attached to the bridge bar, the nose support having at a bottom portion thereof a second fastening portion for removably fastening the lens, the second fastening portion being disposed opposite the first fastening portion; and a lens for removably attaching to the first and second fastening portions, the lens being attached to the eyewear frame by only the first and second fastening portions.
- Other objects and advantages of the present invention will be apparent from the following detailed description.
- The invention will now be described in greater detail in the following detailed description with reference to the drawings in which:
- FIG. 1 is a front perspective view of eyewear incorporating the lens locking device of the present invention;
- FIG. 2 is a rear perspective view of eyewear incorporating the lens locking device of the present invention;
- FIG. 3 is a front view of eyewear showing a lens held by the lens locking device of the present invention; and
- FIG. 4 is a top view of eyewear incorporating the lens locking device of the present invention.
- With reference now to the drawings, the figures generally show eyewear incorporating the lens locking device of the present invention. The eyewear is generally indicated by
reference numeral 10. The eyewear incorporates a frame comprising abridge bar 12 and twotemple bars 14. Thetemple bars 14 may be made so that they are collapsible or foldable. As shown, each of thetemple bars 14 comprises a fronttemple bar portion 16 and a reartemple bar portion 18 connected by ahinge 19. See FIG. 4. However, the temple bars may be one piece temples as is conventional. Thetemple bars 14 are coupled to thebridge bar 12 athinges 20 in conventional fashion. Thebridge bar 12 has anose support portion 22 attached thereto. As shown, thenose support portion 22 provides a place for the eyewear to be supported upon the nose of the wearer. Thenose support portion 22 may be formed integrally with thebridge bar 12. However, it need not be formed in this way and may be a separate attachable portion attached to thebridge bar 12. - The eyewear according to the invention comprises a first fastening portion, illustratively, a
first channel portion 24 located at approximately the center of the bridge bar with the channel facing downwardly. See FIG. 1. Thenose support 22 includes a second fastening portion, illustratively asecond channel portion 26 having its channel facing upwardly. Thechannel portions lens 28 therebetween, preferably a single piece lens. Thelens 28 is snap fitted between the twochannel portions corresponding nose notch 29 in thelens 28, maintains thelens 28 in its centered position with respect to the frame of the eyewear. The channels of the two channel portions have a width sized to receive thelens 28 therein, so preferably, they have a width no smaller than the thickness of thelens 28. - Further, the first and second fastening
portions - Furthermore, either or both the lens and the eyewear frame are made flexible to facilitate the snap in fastening of the lens to the first and second fastening portions. If the lens is flexible, the eyewear frame need not be flexible. If the lens is rigid, the frame can be made flexible. Alternatively, both the frame and lens can be made flexible.
- The
fastening portion 24 is arranged substantially only near or about the center of the bridge bar, e.g., thechannel portion 24 only extends a short distance along thebridge bar 12 adjacent the center of the bridge bar. - According to the invention, various interchangeable lenses may be attached to the eyewear by the fastening
portions fastening portions - According to the invention, the
removable lens 28 is held from near the center of the eyewear only which means the shape and size of the lens can be controlled. A large portion of the edge of thelens 28 does not interfere with theframe 12, thus maintaining the original shape of the lens and preventing distortion of the lens. Further, attachment is simple. The lens is easily fastened between theportions - FIG. 3 shows a
lens 28 and one example of anotherlens 28A shown in dotted lines illustrating how differently shaped lenses may be fitted between theportions - As shown in FIG. 4, the
frame 12 does not interfere with the lens and the lens keeps its shape despite movement of the frame. - Although the present invention has been described in relation to particular embodiments thereof, many other variations and modifications and other uses will become apparent to those skilled in the art. Therefore, the present invention should be limited not by the specific disclosure herein, but only by the appended claims.
