DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(16) FIGS. 1-24 depict preferred embodiments of eyewear and modular pods. Eyewear may comprise a lens frame portion, a first arm, and a second arm. A first hinging portion using hinging structures known in the arts may be positioned between the first arm and lens frame portion, and a second hinging portion may be positioned between the second arm and lens frame portion. The lens frame may comprise a first and second lens portion and a bridge portion that connects the first and second lens portion. Lens frame may comprise a variety of materials known in the arts of eyewear construction, such as TR90 or TR90-NZZ plastic-type materials. First arm and second arm may comprise a variety of materials known and used in eyewear, and each said arm extends from a front portion of the arm to a back portion of the arm.

(17) Lens frame may further comprise a first lens and second lens, and exterior side perpendicular to the first and second arms, and a facial side opposite that of the exterior side of the lens frame. The bridge portion of the lens frame may have a side perimeter that provides a lens slot into which a first lens and a second lens may reside securely, the lens slots and respective lenses mating in a co-planar relationship. The bridge portion may further comprise at its facial side a facial perimeter, and near which a groove that may closely track portions of or the entire the facial perimeter, but with a smaller circumference. In another embodiment, the groove may be set within a recess of the facial side of the bridge portion, the recess also following a similar track of the facial perimeter, but with a smaller circumference so the recess may be inset of the facial perimeter.

(18) Modular pods may be positioned at locations on the eyewear. Pods may comprise moldable plastic, such as TR90 or TR90-NZZ, and/or with elastomeric materials such as rubber and other materials known to provide flexure. In an embodiment of the invention seen in FIG. 1, a first arm modular pod and a second arm modular pod are shown as being deployed at least partially within the first arm and second arm, respectively, and may comprise a front end of the pod and a back end of the pod, correlating to a front portion of the first arm and a back portion of the first arm. Each arm modular pod may be positioned proximal to the front portion of its corresponding arm, or near the hinging portion.

(19) Each of the first and second arm modular pods may resemble a self-contained oval as indicated in FIGS. 6(f) and (g), the narrow end of the oval positioned at the front end of the modular pod. In other embodiments of the invention, the arm modular pods may comprise other structures having convex and/or concave aspects, such as a teardrop with an apex at the front end of the arm modular pod and oriented towards the front end of the arm pod. Arms of the eyewear connect to the lens frame portion, either directly or through hinging or other structures. As embodied in FIG. 1, a first arm may comprise a modular pod disposed between a front portion of the arm and the back portion of the arm. Shown in FIGS. 1-2, pods may be molded into the arms seamlessly so that the respective margins between the pods and arms are unbroken or flush. In other embodiments, pods may break out or protrude from the arms. The modular pods may have frame portions that reside within the frame and nonframe portions that do not reside with the arms of the frames. In another embodiment, modular pods are self-contained, elastomeric in nature, frictionally fit into an accessible void in the arm frame, and removeable so that they may be replaced after continuous use if breached by, for example, a direct and/or sharp impact.

(20) Arms may have 3 dimensional geometry as shown in FIG. 5, with the perimeter of the each arm comprising a margin line. In an embodiment of the invention shown in FIG. 3, a modular pod placed the arms may exceed the margin line of the arm so that at least a portion of the modular pod exists outside of the margin line.

(21) As shown in FIGS. 5, 6G and 6H, modular pods may comprise an interior portion and an exterior portion. The interior portion may hold a volume of media that is lighter than water, such as air. In FIGS. 4a-b, pod is shown to include a resilient element positioned about the interior portion of the modular pod. Resilient element as shown in FIG. 4b may generally cover the nonframe portions of the modular pods. Resilient element may further comprise a thickness that is greater towards the front portion of the pod than it is to the back portion of the pod, or to the back portion of the arm, so that the pod has a greater volume towards the back portion of the pod than the front portion of the pod. Continuing with FIGS. 4a-4b, resilient element may comprise a channel deployed about the exterior portion of the modular pod. The channel may increase in depth as it travels to the back portion of the pod in a coaxial relationship with the arm. In other embodiments not shown, channel may be positioned on the interior portion of the pod, the top or bottom portions of the modular pod, or about frame portions of the modular pod.

(22) The modular pod is positioned generally in the temple region of the first arm and at the second arm, between a front portion of each arm and a back portion of each arm. Modular pod is shown with a teardrop design in FIGS. 1 and 12, with an apex of the tear oriented towards the front of the front end of the modular pod. Other configurations and arrangements are within the scope of the invention for the modular pod to resemble a sphere, an oval, or other shapes having convex, concave or angular aspects.

(23) In an embodiment shown in FIG. 1, a bridge modular pod may be positioned at the connecting portion of the eyewear, or at a center of the lens frame portion. The bridge modular pod may include convex and concave aspects that allow the bridge modular pod to directly or indirectly interface with anatomy of a user of eyewear, specifically, the nasal ridge and root of a human nose. In an embodiment shown in FIGS. 1, 10 and 11, the bridge modular portion comprises a mold of a prototypical human face, resembling a reverse model of the nose anatomy described above. Bridge modular pod may be constructed of an elastomeric material such as a high-density silicone or other rubber-like materials known to provide flexure. Bridge modular pod may be removeable and replaceable in an embodiment of the invention, and replacement bridge modular pods may be selected from a variety of colors and resilient elements as described herein. In yet another embodiment, a bridge modular pod may be customized to a purchaser's nasal root anatomy before mating to the lens frame portion. A digital or physical model may be take of the purchaser's nasal root anatomy, replicated, and created by 3D printer or other fabrication means.

(24) In FIGS. 15-20, bridge modular pod may be positioned within a recess of the facial side of the lens frame portion. In embodiments not shown, bridge modular pod may be a self-contained unit that is formed to frictionally fit within a recess of the facial side of the lens frame portion. Recess may be defined by a lip positioned proximal to the facial perimeter, the lip further having a concave aspect that may lock in the self-contained bridge modular pod. Self-contained bridge modular pod may further mate with the facial side of the lens frame through the use of silicone glues and other adhesives.

(25) Looking at FIGS. 14 and 20, a bridge modular pod may be over-molded into the groove of the facial side of the lens frame portion and reinforced with locking hooks. In an embodiment shown in FIGS. 15-20, the groove is positioned in the recess portion of the facial side of the perimeter, shortening the distance between the lens frame and the face of the user by approximately 4 mm, though the difference may be greater or lesser depending upon needs of a particular line of eyewear.

(26) In an embodiment of the invention, the bridge modular pod may further comprise an interior and an exterior, and a resilient element. The resilient element may be positioned at either the interior or exterior of the bridge modular pod and may populate a partial portion of the bridge modular pod or the entire area bridge modular pod. In an embodiment, the resilient element may cover the exterior of the bridge modular pod.

(27) Resilient element may comprise a framework of individual cells. Individual cells may be filled with air or constructed solid throughout. As shown in FIG. 21a-21b, resilient element comprises individual cells arranged about the bridge modular pod that resembles a honeycomb.

(28) In another embodiment, the resilient elements may be positioned in adjoining areas that adjoin the lens frame or arms where modular pods are deployed. In an embodiment show in FIGS. 8 and 9, resilient elements are positioned at interfaces of the first and second lens portions with the bridge modular pod. In this embodiment, resilient element may be fixably attached to the frame and attached to a modular pod, either directly or indirectly.

(29) In an embodiment of the invention, the bridge modular pod comprises a high silicone material. Other materials within the scope of the invention may include rubber or other elastomeric materials. The eyewear bridge may be understood to provide greater cushioning, comfort and shock absorption to the areas interfacing the nasal ridge or root of the nose, protecting both the modular pod from rupture and the human nasal root and bridge from impact. As a user experiences additional impacts to the frontal side of eyewear, the modular design proved to be less susceptible to leakage of air than other, joined or welded air chambers.

(30) An unexpected benefit to deploying a bridge modular pod outside of the lens frame, as shown in FIGS. 22-23, is that lessening the likelihood of fracturing the eyewear, especially when its frame materials are of a rigid plastic or metallic make. Applicant found that by placing a modular pod outside of the lens portion of the frame, said frame and arms were less likely to rupture and fragment into pieces that could cause injury to the eye of the user. Testing of the embodiment of eyewear shown in FIG. 23 confirmed that it passed a high mass impact test and a high velocity impact test of 150+ft/s without breaching the modular pods or compromising structural integrity.

(31) An embodiment of the invention shown in FIGS. 1-3 comprises an arrangement of three (3) modular pods upon the improved floating eyewear. The relationship of the 3 modular pods may be imagined as triangulation, as seen in FIG. 3. In another embodiment, other modular pods may be added in addition to the three (3) modular pods depicted. The additional pods may fall near the lines of triangulation that exists between the three (3) modular pods.

(32) In the embodiment depicted in FIG. 24, the eyewear comprises a frame having lens frame portion, a first arm and a second arm. Modular pods are placed: 1) a first arm modular pod at the first arm near the front portion of the first arm, 2) a second modular pod at the second arm near the front portion of the second arm, and 3) a bridge modular pod generally at a center of the lens portion adjacent to the bridge and on the facial side of the lens frame portion. In open waters, this arrangement of modular pods with respective air volumes maintain the lens frame portion in a perpendicular relationship with the surface of water, and the arms in a parallel profile with the surface of water. The afore-described position on the surface of open water shall be referred to herein as a preferred profile of the floating eyewear.

(33) Applicant found that bridge modular pod outside the lens frame portion displaced enough weight from the lens frame to, when arranged in combination with the arm modular pods, enabled a preferred profile of the eyewear a preferred profile on water. Applicant discovered that this inventive eyewear regained or maintained the preferred profile of the lens frame portion perpendicular to the surface of the water even when subjected to turbulence, waves, and physical contact that briefly submerged the eyewear.

(34) The specific dimensions of floating eyewear and its modular pods can vary within the scope of the present invention. Determining whether eyewear may meet the preferred profile of floating eyewear may be derived from the following expression addressing the properties of the eyewear portions and modular pods:

(35) V2 is the displacement of the lenses

(36) L is the buoyant force of the lenses

(37) F1 is the buoyant force of the lens frame portion

(38) F2 is the buoyant force of the first and second arms and hinging portions

(39) B1 is the buoyant force of the first arm modular pod

(40) B2 is the buoyant force of the second arm modular pod

(41) B3 is the buoyant force of the bridge modular pod.

(42) SG2 is the specific gravity of the material from which the lenses are made

(43) Assuming that L=V2× SG2, then if F2<B1+B2+B3+L+F1 the eyewear should float in a preferred profile of the eyewear on the surface of the water, which is understood to have a specific gravity of 1 g/cm3.

(44) It is not enough to calculate an overall specific gravity of the eyewear to that equal less than that of water, or 1 g/cm3. As described above and incorporated into the expressed formula, a preferred profile of the eyewear on the surface of open water requires the displacing the lens portions of the frame sufficiently to not sink and turn its facial side to a profile that is parallel with water surface. The facial side typically resembles a concave bowl when turned upwards and parallel to the water surface, which exposes it to the weight and downward pressure of water. By meeting the above standard of keeping the lens frame portion afloat, the eyewear will be capable of floating in a sustained fashion that enables its retrieval.

(45) In another embodiment of the invention, reflective portions may be included in lens portion of the floating eyewear, so that the eyewear signals a user tasked with retrieving the eyewear that is floating in a preferred orientation. Reflective portions may include lenses widely known and used in the arts. Reflective portions may also be applied to the lenses of the eyewear to enable the reflection of sun or other light source.

(46) Another embodiment of the invention regards a line of floating eyewear that uses series of modular pod sizes. The modular pods may have similar shapes but comprise a series of sizes that contain different volumes of media the enabling floatation with different configurations and weights of eyewear frames. In this embodiment, a kit is provided with series of modular pod molds (P) and series of eyewear frames (F). By way of example, the series of modular pod molds may take the form of hollow ovals of increasingly larger sizes that may fit a variety of frames manufactured to float. The eyewear frames may be equipped for a variety of functionalities—for example prescription lenses, impact resistance, turbulent conditions, aesthetic design choices, disposable use, all of which affect the weight of the frames and especially the lens frame portions. By providing the described kit, a maker of the improved floating eyewear may reliably choose the modular pods necessary to enable the floatation of the eyewear as it should properly float atop the water in order to prevent sinking.

(47) Other embodiments of the current invention will be apparent to those skilled in the art from a consideration of this specification or practice of the invention disclosed herein. Thus, the foregoing specification is considered merely exemplary of the current invention with the true scope thereof being defined by the following claims.
