## Background
REFERENCE TO RELATED APPLICATIONS
The present application has one pending application at the time of filing. It is filed on Oct. 15, 2013, by the same inventor herein and is titled “Modular Eyeglasses With Interchangeable Temples And Facades”, U.S. application Ser. No. 13/998,247.
BACKGROUND OF INVENTION
a. Field of Invention
The present invention generally relates to glasses worn on the head, namely, eyeglasses, sunglasses, prop glasses, and combinations of these, wherein a user may add, remove or interchange various selections of facades to glasses. These facades may cover the front of the main frame, its periphery or both. Thus, a single pair of glasses may have different colors, shapes and may include or exclude facades of different colors shapes and styles. The facades are sections of cover materials that have no lenses and cover part or all of the frames that are revealed from a front and/or a side view. That is, they are generally decorative, but also add strength to and protect the main frame from damage (sunlight, dropping, scratching, etc.). With the present invention, a single pair of prescription glasses or sunglasses can go from conservative office styles to neon colors, to alligator, cloth, polished or shiny metal or leather trim. Thus, the facades may use any colors, shapes and materials of construction that have been used in the glasses industry, as well as others not yet utilized.

DETAILED DESCRIPTION OF THE EMBODIMENTS
The present invention modular eyewear enables incredible diversity for eyewear users by offering unlimited possibilities for interchangeable facades using a single set of glasses. Adults can have fancy dress glasses, casual glasses, bright color glasses, leather, metal and cloth designs, as well, for a small fraction of the cost of multiple pairs of prescription glasses. Children who may have been shy or self-conscious of wearing glasses will now look forward to making facade fashion selections each day, even color-coordinating with their clothes, simply by building a collection of different colors, designs, shapes and even cartoon characters.
FIG. 1 is an oblique view of an embodiment of a present invention modular facade and eyewear that includes a central frame with temples shown generally as eyewear 1a and a full coverage facade 1b. The central frame 3 has eyeglass supporting members 5 and 7, containing eyeglass 10 and eyeglass 12, respectively. The term “eyeglass” as used herein, means any lens described above or below made of any lens material available. Central frame 3 also has a bridge member 9, which includes a central locator protrusion 37. In this case, the central locator on frame 3 is a protrusion that corresponds to a recess or orifice 35 on facade 1b, but, alternatively, the recess or orifice could be on the frame with a corresponding protrusion on the facade. Central frame 3 further includes ends 11 and 13. In this embodiment, ends 11 and 13 are opposing corners that include hinges, such as hinge 15, as well as facade attachment locks such as facade lock 39 (protrusion).
Facade 1b has a bridge section 33 with central alignment component, here, orifice 35, and full eyeglass support member covers 21 and 23 with both frontal cover portions and peripheral cover portions 25 and 27. Opposing end pieces 26 and 28 include lock orifices 29 and 31. These are attached to central frame locks such as lock 39. Additionally, central frame 3 has front and peripheral track guides (recessed here, but could be protruding tracks) such as upper peripheral track guide 41 and lower peripheral track guide 47. Corresponding tracks are included inside facade 1b to fit into the central frame guides. These are shown in detail in FIG. 2. The central alignment component orifice 35 is adapted to receive and nest with central locator protrusion 37 of frame 3. They are preferably designed to snap or fit snuggly so that both an alignment/positioning action and an attaching action are both achieved. Further, this essential component (orifice 37, or alternatively a recess or protrusion) may be any shape, be either horizontally or vertically elongated shapes are preferred as these will simultaneously locate the facade on center and level it.
FIG. 2 is a partial side cut view of the embodiment of a present invention facade and eyewear of FIG. 1 showing the fitting of the full coverage facade 1b on the central frame 3. It shows a section of eyeglass 12 and eyeglass supporting member 7. Eyeglass support member cover 21 of facade 1b includes frontal and peripheral tracks (protrusions, such as track 48 positioned in track guide 41 and track 49 positioned in track 47.). As now can be seen, the tracks and track guides maintain a fixed position for the facade 1b on central frame 3 and hold them in place during use, including sudden movement of the head by a user (wearer). A user may select a facade from different shapes, colors, textures, etc. and snap them on and off and interchange them as desired.
FIG. 3 is an oblique view of another embodiment of a present invention eyewear 30a and a frontal coverage facade 30b. The central frame 53 has eyeglass supporting members, such as eyeglass supporting member 99, containing eyeglass 10 and eyeglass 12, as shown, and has track guides similar to those of central frame 3 in FIG. 1. Central frame 53 also has a bridge member 59, which includes a central locator protrusion 61. In this case, the central locator on frame 53 is a protrusion that corresponds to an orifice 85 on facade 30b, but, they could be reversed, i.e. switched positions and still function within the scope of the present invention. Central frame 53 further includes opposing corners that include hinges, such as hinge 55, as well as facade attachment locks such as facade lock 89 (protrusion). The hinges connect with temples 67 and 69. Facade 30b may be removed and replaced with functionally similar facades of different designs, shapes, colors or other unique features.
Facade 30b has a bridge section 83 with alignment orifice 35 and has frontal eyeglass support member covers 71 and 73. (Note that in this embodiment, there are no peripheral cover portions as in FIGS. 1 and 2.) Partial or design peripheral portions could be included as well, e.g., peripheral colorful wave or sinusoidal designs. Opposing end pieces, such as corner 86, include lock orifices 79 and 81. These are attached to central frame locks such as lock 89 described above. Additionally, central frame 53 has front and peripheral track guides (recessed here, but could be protruding tracks) such as track guides 91 and 99. Corresponding frontal tracks are preferably included inside facade 30b to fit into and attach to the central frame guides. These are shown in detail in FIG. 4.
FIG. 4 is a partial side cut view of the embodiment of a present invention of FIG. 3 showing the fitting of the frontal coverage facade 30b on the central frame 53. It shows a section of eyeglass 62 and the corresponding eyeglass supporting member of frame 53. Frontal eyeglass support member cover 71 of facade 30b includes frontal tracks and attaches to frame 53. As now can be seen, the tracks and track guides maintain a fixed, secured position for the facade 30b on central frame 53. A user may select a facade from different shapes, colors, textures, etc. and snap them on and off and interchange them as desired.
FIG. 5 is an oblique view of another embodiment of a present invention modular facade and eyewear. It includes eyewear 1a and a peripheral coverage facade 30b. (Because the eyewear 1a is the same component as eyewear 1a in FIG. 1, it should be noted that here, as well as elsewhere in this document, identical numbers in the drawings are referencing identical parts and as these parts are repeated in subsequent drawings, need not be repeated and called out for each occurrence.)
Facade 30c has a bridge section 133 with alignment orifice 135 and has peripheral eyeglass support member peripheral covers 125 and 127, including tops, such as top 137. Partial or design frontal portions could be included as well, e.g., frontal (hanging) triangles or leaf sections. Opposing end pieces, such as corner 139, include lock orifices, such as lock orifice 131. These are attached to central frame locks such as lock 39 described above. Additionally, central frame 53 has front and peripheral track guides (recessed here, but could be protruding tracks) such as track guides 91 and 99. Corresponding peripheral tracks (not shown) may be included inside facade 30c to fit into and attach to the central frame guides. These are shown in the blown up detail in FIG. 6.
FIG. 6 is a partial side cut view of the embodiment of the present invention of FIG. 5 showing the fitting of the peripheral coverage facade 30c on the central frame 3. It shows a section of eyeglass 12 and eyeglass supporting member 7. Eyeglass support member peripheral cover 125 of facade 30c includes peripheral tracks (protrusions, such as track 138 positioned in track guide 47). As now can be seen, the tracks and track guides maintain a fixed position for the facade 30c on central frame 3. A user may select a facade from different shapes, colors, textures, etc. and snap them on and off and interchange them as desired.
FIG. 7 is a block diagram showing some detailed features of the present invention interchangeable facades 200. Blocks 201, 203 and 205 indicate that the facades may be frontal (covering only at least a portion and typically most or all of the front of the frame, peripheral (only the periphery of the frame, i.e., the part that is not the front or the back of the frame), or a combination of both frontal and peripheral, respectively. Block 205 specifically shows the possibilities of coverage for various combination facades. Block 207 establishes that any of these may be full top and bottom coverage, or upper (only top) or lower (only bottom) pieces.
FIG. 8 is a block diagram showing some other detailed features of the present invention facades 210. Block 212 indicates various materials of construction, and block 214 indicates the types of attachment mechanisms that may be used to attach the facades to the frames. Block 216 describes some possible surfaces. In addition to those listed, plain (undecorated) surfaces are often used; topographies mean three dimensional design features, such as lightning strikes, animals, hearts or any other adornment that is raised or protruded or both. Patterns simply mean repeated two or three dimensional designs, e.g., plaid, blocks, stripes, diamonds, etc. One radical facade of the present invention might be chrome metal with exaggerated diamonds, like on the footings and cabinets of fire trucks; another might be a colorful Scottish pattern, or alligator skin. As indicated in block 218, these facades may have characters on them, such as Smokey the Bear, Hulk Hogan, Spider Man, Daffy Duck, etc, or may have logos, such as the famous Mercedes Benz logo, or famous designer initials.
FIG. 9 is an oblique view of another embodiment of the present invention modular facade and eyewear, but also illustrating interchangeable temples. There are full coverage half height facades, utilizing the frame of FIG. 1, namely eyewear 1a, but showing separate upper and lower facades 70b and 70c, respectively, with full coverage, i.e., frontal plus peripheral coverage. In this Figure, extension 28 has a half shell hinge receiver to its forward area and a recessed area with a catch and push button, similar to button 43 on extension 26. It should be understood that in this embodiment, the temples 17 and 19 are connected to the extensions, which are themselves connected to the hinges. Also, button 43 is a catch/push button mechanism attached to the extension 26 and. when connected, will be protruding from orifice 45 of temple 19. There is symmetrically opposite hidden button on the inside of temple 17 as well. By pressing these buttons (such as button 43) and sliding the temples (such as temple 19) away from central frame 3, the temples 17 and 19 may be removed and replaced with functionally similar temples of different designs, shapes, colors or other unique features. These temples are featured in a related application cited above.
Upper facade 70b has a bridge 161, left and right top cover sections 151 and 153, and ends, such as end 157, with lock Orifices, such as lock orifice 159. Bridge 161 has a central alignment orifice 163. This may be attached in the same manner as facade 1b discussed above.
Lower facade 70c has a bridge 177, left and right bottom cover sections 171 and 173, and ends with lock tracks, such as track 175. Alternatively, eyewear bridge 9 could have two alignment locator protrusions, one above the other and one for the upper and one for the lower facades 70b and 70c, in which case lower facade bridge 177 could have and alignment orifice.
FIG. 10 shows an oblique view of a present invention modular facade, showing an upper frontal coverage facade 110. It has a bridge 111, left and right top frontal cover sections 113 and 115, and ends 117 and 119, with lock orifices, such as lock orifice 121. Bridge 111 has a central alignment locator orifice 123. This may be attached in the same manner as facade 1b discussed above to any eyewear the same as or similar to eyewear 1a above.
FIG. 11 shows an oblique view of present invention modular facade, showing a lower peripheral coverage facade 140. It has a bridge 141, left and right bottom peripheral cover sections 143 and 145, and ends 147 and 149, with lock orifices 151 and 153. Bridge 141 has a central alignment locator orifice 155. This may be attached in the same manner as facade 1b discussed above to any eyewear the same as or similar to eyewear 1a above.
FIG. 12 shows a side cut view of one preferred embodiment of a present invention modular eyewear 200 that is cut through the bridge 209 and across a temple 205. The central frame 203 has two eyepieces but one is cut out of the figure and one is shown, namely, the right eyepiece, that is, eyeglass supporting member 201 and eyeglass 207. This central frame 203 cut bridge 203 is shown in profile in FIG. 13 to more fully illustrate attachment mechanism details. They are the location/positioning (alignment) recess 227 and peripheral recesses 223 and 225. Referring back to FIG. 12 and in conjunction with FIG. 13, they collectively show one preferred arrangement for the facade attachment and central location and alignment features. Thus, facade 210 includes the full coverage (peripheral and frontal) and has a frontal cover portion 211 and a peripheral cover portion 213. It also has a bridge covering 221 that has a top, a bottom and a front section with an open back, so as to slip onto bridge 209, as shown. It has central locator protrusion 215 that fits into bridge recess 227, and protrusions 217 and 219 that pop into bridge recesses 223 and 225. These, along with other attachment points (not shown but such as are described above) present an efficient, easy to attach, well attached connection between the facade 210 and the frame 203.
Although particular embodiments of the invention have been described in detail herein with reference to the accompanying drawings, it is to be understood that the invention is not limited to those particular embodiments, and that various changes and modifications may be effected therein by one skilled in the art without departing from the scope or spirit of the invention as defined in the appended claims. For example, some of the attachment channels or rails or other mechanisms may be partial, rather than full length or may be at multiple points rather than continuous.
