Description:
FIELD OF THE INVENTION 
     The present invention relates to the field of sports &amp; safety eye wear and more specifically to eye wear having improved lens retention and members which may be added to the bottom edge of eye wear lens members to form an improved goggle structure. 
     BACKGROUND OF THE INVENTION 
     Conventional sports &amp; safety eye wear currently exist which allow the user a wide angle of view. This type of eye wear is typified by a singular or two lenses which extends from the outside of one of the wearer&#39;s eyes and extends across to the outside of the other of the wearer&#39;s eyes, and only partially interrupted by the structures which support the eye wear at the bridge of the nose. This is a partial interruption since the support structures are typically supported only by the center of the singular lens, which is in turn supported by the upper portion of the frame. The support structure extends inside the singular lens to garner support from the user&#39;s nose, and the singular lens is kept outward and generally downward opening downward and lower on the user&#39;s face. Thus the wide view afforded by the singular lens comes at the expense of having a wide open space between the lower edge of the lens and the user&#39;s face. The same issues occur in two lens eye wear in the wide open space between the lens &amp; user&#39;s face. 
     Goggles hug and seal with the face of the user to isolate the eyes as much as possible from wind and debris. The sealing can occur around each eye, and the protected area most often includes the bridge of the nose. Even where the enclosure extends across the area adjacent both eyes, goggles still generally restrict the view of the user. The restriction usually comes with the support structure which is used to seal against the face and closely adjacent to the eyes, and typically surrounds the entire lens fully. 
     In terms of usage, a user is faced with having to buy both goggles and conventional sports glasses, and to use the appropriate eye wear depending upon circumstances. Where debris is severe enough, goggles are worn at the sacrifice of an expanded viewing angle, more heavily structured and bulky. Where conventional open sports eye wear are worn, the user suffers the debris, particularly wind and dust, which may enter the eyes behind the lenses. In addition, conventional sports eye wear, by having a significant gap on the face, even where the gap between the bottom of the lens and the face surrounding the eyes is low on the face, admits significant amounts of light. Where the user gazes down, there will be a sudden change in light levels, which can both annoy the user and stress the user&#39;s eyes. The effect is most pronounced where the lens is particularly dark. 
     Another aspect of eye wear not served well by goggles includes the ability for comfort and ventilation. A good seal is usually achieved at the expense of ventilation and with significant pressure on the face surrounding the eyes. In some cases specialized ventilation ports are formed in the side walls of the lens support structures, but they are not always located properly or structured to provide adequate ventilation. Even where adequate ventilation is provided, the goggles do not provide a comfortable fit. 
     Goggle framing is usually fairly durable and allows for a long useage life. The seal used in conventional goggles is less able to withstand vigorous use, and tends to break down over a relatively short period of time. The seal break down usually occurs far short of the full use life of the overall goggle. Therefore, the ability to interchange goggle seals is important in extending the life of a goggle. 
     What is therefore needed is a new and improved sports eye wear structure including at least one lens member that may be held strongly in a frame and having structures which engage the lens member along the bottom edge, separate or in conjunction with a top and/or side edges, and which will permit a very gentle sealing with the face to inhibit wind and debris from entering the user&#39;s eyes and which will block unwanted light from the eyes. Further, to benefit interchange ability, the structures which forms the seal along the bottom portion of the lens or lenses should be removable so that a wearer can use the same eye wear in an open or closed format as the user wishes. 
     SUMMARY OF THE INVENTION 
     The eye wear includes a single piece lens or two lenses which may or may not be supported and captured within a frame using a ramped protrusion from the lens which engages a matching accommodating void and lies off of a main slot in the frame which engages the upper edge of the lens. Possible lenses include removable lenses, anti-fog lenses, as well as systems supplied as lens-only. 
     The lower lens is engaged by a fitted member having a sealing structure extending to one side. The side of the sealing structure extension which meets the face preferably has a smooth, non-porus surface to avoid collection of debris, body oil, although since the member is removable and easily washable, an open cell foam or other porus material, as well as a completely closed foam, non-externally porus material can be used as the sealing structure. The sealing structure which may have a finished end surface, would also be permissible. The sealing structure may operate in conjunction with a built-in or removable side shield and may accommodate a permanent or removable nosepiece. 
     The fitted member engaging the lower edge of the lens or lenses and which may extend from a point near the outermost edge of one side of the eye wear, or face and to the nose area. The end of the fitted member can be shaped to provide maximum accommodation of the nose support member and help seal in a manner complementary to the nose support member. 
     In another embodiment, the fitted member can extend from one side of the eye wear, completely through to the other side of the eye wear and form the structure which supports the lens against the nose. In both embodiments, the fitted member is intended to include the possibility of alteration by the user by cutting, trimming and the like to obtain maximum conformance to the particular shape of the user&#39;s eye wear. 
     The fitted member may include a plastic support piece having a generally U-shaped cross section for engaging the lower edge of the lens, and a small shelf, extending from the bottom portion of the U-shape which helps to support the sealing structure which seals against the face. Along the length of the shelf, a series of elongate rectangular ports assist in handling drainage of any sweat, or any rain or moisture which might have entered the eye shield area and collect along the bottom of the lens. 
     The plastic support piece will typically be extruded or injected and may be heat formed to a specific shape where it is desired to provide eye wear as a kit. Where the fitted member is provided as a retro-fit device for use with non-specific shapes of lenses, the fitted member will ideally have a series of angled slots along its length to permit bending conformance to a wide variety of shapes of lens edges without twisting or distorting the material. In another embodiment, shorter sections of material may be fitted along the lower edge of lens members. Attachment of any of the structures of the invention may be had by gluing, hooking or clipping, chemical bonding, welding, friction fit, screws, pressure, male and female pins and holes, attachment channel and groove, hook and loop members, magnets, suction, static attraction, melting or solvent, and independent attachment to other structures including any portion of the eye wear frame, temples, strap or lens. The structures of the invention may include homogeneous structures, or structures made of two or more different types of material. Materials which can be used include wood, metal, plastic, leather, cloth/fabric, foam, rubber, conforming material and any other material capable of making the seal now known or later discovered. Manufacture of the structures of the invention can occur by extrusion, injection, shaping, forming, molding or other manufacturing steps now know or later discovered.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     The invention will be best described with reference to FIG. 1 which illustrates a perspective view of sports eye wear  11 . Eye wear includes a curved frontal support  13 , a pair of folding side temple supports  15  and which may be pivotally hinged to the frontal support  13 . Here, a support strap  16  is shown engaging the ends of the temple supports  15 . 
     Supported solely from the frontal support  13 , a continuous lens  17  is suspended from the frontal support  13 . The lens  17  has a right area  19  and a left area  21  separated by a nose area  23 . The nose area  23  is the smallest vertical extent of the lens  17  and demarks some separation between the right and left areas  19  and  21  respectively. At and below the nose area  23  is a nose bridge support  25  which is attached to the lens  17 . The nose bridge support  25  has a forward lens engaging portion  27  and a rearwardly extending nose bridge engagement portion  29 . The support  25  is typically held in place by notches or other holding structure in the lens  17  which hold the support  25  in place. 
     Immediately below the right area  19  is a fitted member  31  having a fitted engagement piece  33  and a rearwardly extending sealing structure  35 . The engagement piece  33  is typically made of a medium soft resilient plastic which can be slipped onto the bottom of the lens  17 . A second fitted member  37  includes an engagement piece  39  and a sealing structure  41 . 
     Engagement piece  33  follows the contour of the bottom edge (not seen where engaged) of the right area  19  of the lens  17 . Here, the engagement piece  33  covers all of the bottom edge of the right area  19  and stops where the outer edge of the right area turns upward. The extent of engagement piece  33  need not stop here, but can continue upward if desired. At the rear of the curved frontal support  13 , a continuous length of brow padding  43  may be provided. In such a configuration, the eye wear  11  is supported by a combination of the hugging action of the temple supports, the pressure of the frontal support  13  and brow padding against the forehead. 
     If the fitted member  31  were to extend up the vertical edge of the lens  17  of the right area  19 , an enclosed volume surrounding the eyes results. The integrity of the enclosed volume is not as complete as would be the case for a full goggle set, but air movement, and thus movement of debris in the air stream is restricted. 
     In the configuration of FIG. 1, the engagement piece  33  will typically be purchased as a pre-fit to conform to right areas  19  having a generalized bottom edge configuration as shown in FIG.  1 . It is possible that the engagement piece  33  could fit a number of configurations which are different, but which do not extremely deviate from the general shape seen in FIG. 1, or a similar general shape. 
     As can also be seen in FIG. 1, the sealing structure  35  extends up to and may have sealing contact with the rearwardly extending nose bridge engagement portion  29 . The sealing structure  35  may thereby extend beyond the extent of the end of the fitted engagement piece  33  as it approaches the nose bridge support  25 . The fitted engagement piece  33  may also abut the nose bridge support  25  and particularly the forward lens engaging portion  27 . 
     Referring to FIG. 2, a bottom view of the eye wear  11  of FIG. 1 illustrates the rearward extent of the sealing structures  35  and  41 . A more complete view of the relationship of the forward lens engaging portion  27  and rearwardly extending nose bridge engagement portion  29  of the nose bridge support  25  is seen. 
     Referring to FIG. 3, an expanded view taken along line  3 — 3  of FIG. 1 is illustrated. The frontal support  13  has a slot  44  into which the lens  17  fits. The lens  17  has a rearward protrusion member  45  which rises significantly away from the planar extent of lens  17  and which interfits with a matching void  47  and both of which operate to keep the lens  17  secure within the curved frontal support  13 . The overall shape of the member  45  may be round, square or triangular in both side and surface profile, and further configurations will be shown. The frontal support  13  is seen as having a downwardly directed slot  44 , indicated by a lead line to the closed end of the slot, into which lens  17  fits. 
     Referring to FIG. 4, a generalized view of the fitted engagement piece  33  and attached sealing structure  35  is seen. The sealing structure  35  may be relatively long, both to give an adequate reach to the portion of the user&#39;s face being engaged, and to provide a softer fit by providing additional material for compression. The vertical depth of the material of the sealing structure  35  is sufficient to prevent any sagging or undue bending in a vertical direction. The fitted engagement piece  33  is seen as having a front wall  48  and a rear wall  49  both supported by a base member  50 . 
     Referring to FIG. 5, a variation on the design of the fitted engagement piece  33  of FIG. 4 is shown as a fitted engagement member  51  having a fitted engagement piece  53  having internally disposed gripping members  55 . Gripping members help to provide greater holding force by making it easier to mount the engagement piece  53  onto the lens  17  than the force required to remove it. 
     Referring to FIG. 6, a variation on the design of the fitted engagement piece  33  of FIG. 4 is shown as a fitted engagement member  57  having a fitted engagement piece  59  having inwardly tilting preformed side walls  61  to assist in gripping the lower edge of the lens  17  (not shown in FIG. 6 in order to show the degree of pre stress on at least one of the side walls  61 ). The inwardly tilting front and rear walls  61  and  63  help to better distribute the bearing force of the side walls  61  on the lens  17  material to prevent a loosening of the side walls from becoming worn and flared thus preventing good fit of the engagement piece  33 . 
     Referring to FIG. 7, a continuous length of fitted member  65  has a series of generally evenly spaced notches  67  in its fitted engagement piece  69 . The notches  67  are formed in both the front and rear walls, although only a front wall  71  is visible from the vantage of FIG.  7 . The sealing structure  35  extends away from the viewer of FIG. 7, and where the sealing structure  35  is of sufficient height, as will usually be the case, the notches  67  will also extend into its material. The notches  67  are of sufficient depth to enable any length of the engagement piece to bend sufficiently to closely engage the lower edge of the lens  13  at its smallest curvature. In some cases where the sharpest and most gentle curvature spacing is known, the notches  67  will have different depth or different angularity. Areas of slight curvature will have sharply angled notches while areas of sharp curvature will have large angled notches. 
     The fitted member  65  may be available in a continuous length to enable the user to cut a length to cover as much of the lower edge of a lens  17  as is desired. In addition to cutting the length to suit, the ends can be angle cut to enable the sealing structure  35  to extend beyond the end of the engagement piece  69 , or to allow the engagement piece  69  to extend beyond the end of the sealing structure  35 . In addition, the sealing structure  35  and the engagement piece  69  may be cut in other configurations as are necessary to more closely conform to and accommodate structures on the eye wear  11 . 
     Referring to FIG. 8, in some cases, an eye wear  11  structure may lack a nose bridge support  25 . In this case, a fitted member  75  may be provided having notches  77  in an engagement piece  79  which also has a wide gently sloping notch  81  removed from both a front wall  83  and a rear wall (not shown) and associated portions of the sealing structure (also not shown). The gently sloping notch  81  or curved removal of material from the fitted member  75  will prevent visual obstruction near the nose area  23 . Otherwise, the individual portions between the notches  77  would fan out about the upper curvature of the bottom edge of lens  17  in the vicinity of the upper end of the nose bridge support  25 , causing the visual obstruction. 
     As was the case for fitted member  65 , the fitted member  75  can be manufactured with a central gently sloping notch  81 , and overly long lengths to either side of the notch  81 . The user can position the notch  81  at the nose area  23 , begin fitting the lengths adjacent to the notch  81  and then trim the outer ends of the fitted member  75  to fit the outermost edges of the lens  17  as are needed. 
     Referring to FIG. 9, a modification of the fitted member  31  is seen as a fitted member  85  having a fitted engagement piece  87  and a sealing structure  89  which may have a slightly shorter depth to accommodate a ledge member  91 . The ledge member  91  is parallel to a base member  93  which supports a front wall  95  and a rear wall  97 . The ledge member  91  provides partial support for the sealing structure  89  and carries a series of drainage/ventilation slots  99  to help eliminate any moisture build up within the eye wear  11 , and which moisture may be in gaseous or liquid form. If the sealing structure  89  is sufficiently porus to air, the moisture in the air may exit through both the slots  99  and any other surface of the sealing structure  89  exposed externally. In the case of liquid droplets which may move down the inside of the lens  13 , the slots  99  provide an exit at a point closest to the rear of the rear wall  97 , for the liquid to escape. 
     FIG. 10 is a bottom view of the fitted member  85  and illustrating the regularity of spacing of the slots  99 , and the extent to which the sealing structure  89  extends beyond the edge of the ledge  91 . FIG. 11 is a top view of the fitted member  85  and showing the relationship of the front wall  95 , rear wall  97  and base member  93 . Also seen is the extent to which the sealing structure  89  both overhangs and is supported by the ledge  91 . 
     Referring to FIG. 12, the eye wear  11  is shown where the nose bridge support  25  is replaced by a nose bridge support  101  having an eyeglass frame  103  supported by the rearwardly extending nose bridge engagement portion  29 . With the combination shown in FIG. 12, the eye wear  11  provides an expanded view, double protection for the eyes and yet has a goggle-type enclosure. Also seen are the fitted members  71  of FIG.  7  and the eye wear  11  is seen from a frontal angle of view. The continuousness the sealing structure  35  with respect to the rearwardly extending nose bridge engagement portion  29  is also seen. The sealing structure  35  can be seen through the lens  17  as rising all the way up to the level of the curved frontal support  13 . 
     Referring to FIG. 13, the eye wear  11  is shown where the nose bridge support  25  and eyeglass frame  103  is absent and where the fitted member  75  of FIG. 8 is shown extending completely around the edges of the lens  17  which are not engaged by the slot  44  of the frontal support  13 . The fitted member  65  extends downward from the frontal support and takes a sharp curve naturally before extending toward the center of the eye wear  11  underneath right area  19 , curving upward again and also taking advantage of the notches  77  and up to that point having always curved in a direction compressing the space occupied by the notches  77 . At the bottom of the nose area  23 , the fitted member  65  curves in the opposite direction as it goes over an area which will fit over the bridge of the nose. Here the wide gently sloping notch  81  comes into use by preventing the portions of the fitted member  75  between the notches  77  from flaring widely at the base of the nose area  23 . This prevents obstruction of vision. The sealing member  35  is seen through the lens  17  and illustrated is the sealing member  35 &#39;s extension up to the level of the curved frontal support  13 . A portion of the sealing member  35  can be seen at the front center of the eye wear  11  and below the nose area. The sealing member  35  thus acts not only to seal the eye wear  11  against a wearer&#39;s face, but also to cushion the eye wear  11  against the bridge of the wearer&#39;s nose. 
     Referring to FIG. 14, a sectional view also taken along line  3 — 3  of FIG. 1 illustrates a variation on the rearward protrusion member  45  as a forward extending and rearward extending hemispherical protrusion member  111 . It is hemispherical, with the radius lying on the general plane of the surface of the lens  19 . The protrusion member  111  can be either in the forward position, rearward position or both. The illustration of FIG. 14 shows both forward and rearward structures for completeness. Each of the members  111  shown fit within a matching shaped hemispherical void  113  which lies off to one side of the slot  44  of the frontal support  13 . 
     Referring to FIG. 15, a sectional view also taken along line  3 — 3  of FIG. 1 illustrates a variation in shape of the forward extending and rearward extending hemispherical protrusion member  111 , as a forward and rearward extending equilateral triangular protrusion member  117 . The base of the triangular protrusion member  117  is about the same dimension as its two sides. The protrusion member  117  can also be either in the forward position, rearward position or both and is shown as both for illustration. Each of the members  117  shown fit within a matching shaped equilateral triangular void  119  which lies off to one side of the slot  44  of the frontal support  13 . 
     Referring to FIG. 16, a sectional view also taken along line  3 — 3  of FIG. 1 illustrates a variation on the rearward protrusion member  45  as a forward extending and rearward extending right triangular member  121 . The right triangular member  121  is oriented to facilitate the introduction of the lens  17  into the slot  44  and for a matching void  123  to capture the triangular member  121  within the void  123  to, in a less reversible way, capture the lens  17  within the slot  44 . Depending upon the materials used, the difficulty in removing the lens  17  from the slot  44  will vary. The use of the member  121  will permit a lesser size member  121  to be used to give the same holding strength as another structure with a more reversible shape.
