Title: Safety glasses

Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application claims the benefit of Provisional Application No. 63/274,920 entitled SAFETY GLASSES filed on Nov. 2, 2021, the entire disclosure of which is incorporated herein by reference. 
    
    
     FIELD OF THE INVENTION 
     The present invention relates to the field of glasses, and in particular to a kind of glasses having releasably attachable safety shield members. 
     BACKGROUND 
     Traditionally, glasses such as reading glasses, corrective eyeglasses, and sunglasses are purchased for the utility of the lenses, whether it is to help a user see clearly, read, or protect the user&#39;s eyes from the sun. Safety glasses have also been developed which, in addition to protecting a user&#39;s eyes or augmenting a user&#39;s vision, protect the side of a user&#39;s face by use of one or more face shields. However, these prior developed glasses either do not provide an option for easily removing the additional face shields, or lack the ability to quickly and easily modify the glasses by applying and/or removing the safety shields. Moreover, at present, sunglasses, prescription glasses, and/or smartglasses are not quickly and easily modifiable to include safety shield members configured to shield one or more sides of a user&#39;s face, and it would be advantageous and desirable to glasses users to be able to quickly and easily modify their glasses (e.g. smartglasses) to include protective shields, in some scenarios, while retaining the functions of being able to connect their smartglasses with other mobile devices (e.g., smartphones). 
     Prior-developed side shields for glasses, for example, Slip-on Clear Side Shields (https://www.amazon.com/Shields-Prescription-Glasses-Protection-Eyeglasses/dp/B08L3R5JVL/ref=asc_df B08L3R5JVL/?tag=hyprod-20&amp;linkCode=df0&amp;hvadid=475794949169&amp;hvpos=&amp;hvnetw=g&amp;hvrand=11603898907150195 536&amp;hvpone=&amp;hvptwo), are configured to slide onto the temples of glasses, and either are difficult to be removed or cannot altogether be removed by a user while the user is working, for example, while the user is working with gloves. Moreover, these prior-developed safety shields must be taken off of a user&#39;s face in order to apply or remove the slip-on safety shields onto or from the glasses which hinders productivity. 
     Other prior-developed glasses, for example, the glasses described in U.S. Pat. Nos. 7,850,301 and 8,092,007, have lenses which include magnets to make the function of the glasses modifiable, for example, to enable a user to switch the function of glasses from, for example, prescription lensed glasses, to, for example, sun protective lensed glasses. However, these prior-developed glasses lack the ability to modify the glasses to include facial shield members, for example, to shield a side portion of a user&#39;s face, even while a user is wearing gloves or while the user&#39;s hands are oily or wet. 
     Therefore, there is a need in the art for a glasses system and/or safety shield system which provides users with the ability to quickly and/or easily modify glasses with one or more facial shield members, for example, while wearing the glasses. These and other features and advantages of the present invention will be explained and whose utility and benefit will become understandable to one skilled in the art through the summary of the invention that follows. 
     SUMMARY OF THE INVENTION 
     As described in further detail herein below, the methods and systems, and devices described herein employ a novel design for glasses which may be enabled with wireless communication technology and configured with quick connect magnetic shields to easily, inexpensively and efficiently change or update glasses devices to include eye protective safety shield members.

In some examples, at least one tab member may be a straight tab member (e.g. extending straight up from a top portion of a shield member) and one tab member may be an angled tab member (e.g. extending from a top portion of the shield member at an angle). In some examples, an angled tab member may be curved. 
     In accordance with embodiments of the present invention, the shield members may be formed of a transparent or non-transparent material. In some examples, the material may be a plastic material. In any embodiment, the shield members may be formed of any suitable thermoplastic polymer resin, for example, polyethylene terephthalate (PET) or polyethylene terephthalate glycol (PET-G), acetate, polycarbonate or any similarly suitable plastic material. In some examples, the shield members may be 3D printed. In any embodiment, the shield members may be formed of any material capable of being 3D printed. 
     In some examples, the shield members may comprise a shield portion. In some scenarios, the shield portion may be curved. In some examples, curved shield members may support user comfort and/or prevent obstructing a user&#39;s visual ability (e.g. view). In some embodiments, the shield portion may be curved to correspond to the curvature of glasses&#39; temples. For example, if a given temple is curved to a certain degree, a shield portion may substantially correspond or match the degree of curvature of the temples, such that, for example, the exterior and/or interior surface of the shield portion may be flush with the exterior surface of the given temple. 
     In accordance with embodiments of the present invention, each of the temples may comprise one or more magnet members configured to wirelessly connect the temples to one or more protective shields having one or more corresponding magnet members disposed thereon.

In some examples, the protruding tab members  112  may substantially correspond in shape, size and orientation to receiving holes  104  disposed on the temples  102 . In some examples, the protruding tab members  112  may be adapted to friction fit within the receiving holes  14  of the temples. In some examples, at least of a portion of the protruding tab members  112  may be magnetic. In some embodiments, the protruding tab members  112  may be configured to clip or snap-fit into the receiving holes  104  in the temples. In some examples, the combination of the protruding tabs  112  and the magnet members  114  prevent inadvertent dislodgement of the shield members  110  from the glasses  100 . 
     In some examples, the one or more shield protruding tab members  112  may be configured to extend from a shield member  110  in a straight or angled manner. Advantageously, at least two protruding tab members  112 , for example, a first protruding tab member  115  and a second protruding tab member  116 , may extend from the shield member  110  to support stable connection to the temples  102 , and prevent movement or dislodgment of the shield members  110  from the temples  102 . As shown in the depicted embodiment, in some examples, the first protruding tab member  115  may be a straight tab member (e.g. extending substantially perpendicularly from a top surface of a shield member  110 ) and the second tab member  116  may be an angled or curved tab member (e.g. extending from a top portion of the shield member  110  at an angle). In some examples, the angled tab member may define a curved edge of the shield member  110 . As shown in the illustrated embodiment, in some examples, an angled tab member  112 , for example, the second tab member  116 , may be curved. In some embodiments, a portion of the shield member  110 , for example, a side portion of the shield member  110 , may be formed to abut a portion of the rear side of the front frame  101 . In some examples, a top portion of the shield member  110  may be formed to substantially abut a bottom portion of a temple  102  and/or end piece  103 . In some examples, a portion of the safety shields  110 , the first tab member  115  and/or second tab member  116 , may be formed to abut a portion of the bottom side of the temples. In some embodiments, the second tab member  116  may be configured as a molding, at least a portion of which may be configured to substantially abut at least a bottom portion of the temples. In some examples, a side portion of the shield portion  118  may be configured to substantially abut at least a rear portion of the front frame member  101 . In some examples, the structure of the shield portion  118  and the first and second tab members  115  and  116  may be configured to substantially block small particles (e.g. debris) from nearing or entering a user&#39;s eye. In some examples, the second tab member  116  curves to meet the front frame  101 . 
     In accordance with embodiments of the present invention, the shield members  110  may be formed of a transparent or non-transparent material. In some examples, the material may be a plastic material, for example, a polycarbonate plastic material. 
     In some examples, the shield members  110  may comprise a shield portion  118 . In some scenarios, the shield portion  118  may be curved. In some examples, curved shield members  110  may support user comfort and/or prevent obstructing a user&#39;s visual ability (e.g. view). In some embodiments, the shield portion  118  may be curved to correspond to the curvature of glasses&#39; temples  102 . For example, the temples  102  may be curved a predetermined degree and the shield portions  118  may substantially correspond or match the degree of curvature of the temples  102 , such that, for example, the exterior and/or interior surface of the shield portion  118  may be flush with the exterior surface of the temples  102 . Moreover, at least one side wall of the shield portion  118  may be curved to match the curvature of a front frame of a pair of glasses, for example, such that the side wall of the shield portion  118  may be flush with (e.g., abut) a rear surface of the front frame. In this way, the shield members  110  may effectively prevent matter such as debris from entering an eye area of a user wearing the glasses and safety shield assembly. In some examples, placement of the shield members  110  along a bottom portion of the temples  102  is configured not to interfere with the actuation button  106 , for example, with access to the actuation button  106 . 
     In some examples, the temples  102  of the glasses  100  may include wireless technology, for example, Bluetooth® technology for connecting the glasses to a mobile phone, tablet, or other smart device in order to permit the transmission or playing or receiving of music, phone calls, and other audio by the glasses  100 . In some embodiments, the temples  102  include a microphone (not shown), battery (not shown), bone conduction speakers, one or more printed circuit boards (not shown), a control pad (not shown), a connectivity module and hardware (not shown), and a cellular communications unit and hardware (not shown) which may be configured to enable the glasses  100  to communicate over a wireless network, for example, Bluetooth® wireless networks, cellular wireless networks, WiFi, near field communication and/or other types of wireless technology standards to pair and/or communicate with other electronic devices, for example, mobile devices including smartphones and smartwatches. In some embodiments, other components which are not depicted in the exemplary embodiments disclosed herein, may be incorporated into the glasses  100 . 
     In accordance with various embodiments of the present invention, the liberation of the shield members  110  from the temples  102  may enable users to quickly and/or easily modify a pair of glasses  100  to include a facial safety feature. In some embodiments, a user can add or remove the shield members  110  from the glasses, even when wearing gloves or when the user&#39;s hands are wet or oily. In some examples, the protruding tab members  112  and/or the magnet members  114  disposed thereon support the ability for user to quickly and/or easily add or remove the shield members  110  from the glasses  100 , for example, while wearing gloves (e.g. disposable, utility, safety, or any other similar types of gloves). 
     Moreover, in some scenarios, the ability for the shield members  110  to be liberated from the glasses  100  may enable users of any type of glasses, for example, prescription glasses to wear their glasses during non-safety activities (e.g., when the safety shields would not be needed), and simply add the safety shield members when needed for safety. In some examples, this configuration enables users, for example, prescription glasses wearers, to not have to purchase a second pair of glasses, for example, an additional pair of glasses just for safety application or usage. In accordance with some examples, should a user decide to update enhance or modify their glasses to include a safety feature, the user is able to easily connect and disconnect the shield members  110 , for example, the protruding tab members  112  of the shield members which may have one or more magnet members  114  disposed thereon, to the temples  102 , for example, to the receiving holes  104  disposed on the temples  102 , which may have one or more magnet members disposed therein, configured attract the magnet members  114  of the protruding tab members. Alternatively, should the user decide to use the glasses for a non-safety application, the user would simply disconnect the shield members  110  from the temples  102  by applying a force greater than the magnetic force of the magnet members of the protruding tab members  112  and the receiving holes  104  and/or the frictional force created by the abutment of the side walls of the protruding tab members  112  with the receiving holes  104  of the temples  102 . In this manner, a user may own a single pair of glasses  100  and selectively enhance the utility of their glasses, for example, by adding a safety feature, without having to purchase a second, new pair of glasses, for example, facial safety glasses. 
     In accordance with several embodiments of the present invention, the glasses device  100  disclosed herein may require less material than would be traditionally required, as a user may simply acquire a glasses device having the ability to removably connect to safety shields  110  (e.g., prescription glasses having receiving holes configured to connect to one or more safety shields) without having to purchase two separate types of glasses (e.g., a pair of prescription glasses and a pair of safety glasses). 
     In accordance with embodiments of the present invention, the temples  102  of the glasses  100  can include wireless technology, for example, Bluetooth® technology for connecting the glasses to a mobile phone, tablet, or other smart device in order to permit the transmission or playing of music, phone calls, and other audio by the glasses  100  through bone conduction or other speakers  110 . In some embodiments, the temples  102  may transmit and receive music, phone calls and other audio by the glasses  100  through in-ear or over-ear headphones disposed on or extending from the temples  102 . 
     In accordance with several embodiments of the present invention, safety shield members  110  may be configured to disconnect from the temples  102  without requiring the disconnection of any electronic wires. In accordance with embodiments of the present invention, the safety shield members  110  may be configured to connect to the receiving holes  104  in the temples  102  without disturbing any wires within the temples  102 . 
     In accordance with several embodiments of the present invention, the wireless communication technology of the glasses device  100  may be configured such that disconnecting the safety shield members  110  from the temples  102  does not disrupt the electronic connection between each of the temples  102 . Also for example, the glasses  100  may be configured such that disconnecting the safety shield members  110  from the temples  102  does not disrupt the connection between the temples  102  and a mobile device, for example, a smart device, to which it may be wirelessly connected to. 
     In accordance with embodiments of the present invention, an actuation button (e.g., a control button)  106  may be disposed on one or both of the temples  102  of the glasses  100 . In some examples, the actuation button  106  may be configured to power the temples  102  on or off, or may be used to toggle between different user selection options, for example, to activate a voice control assistant, make a call, or begin playing music. In some embodiments, different pressing gestures of the actuator button  106  may activate different functionalities of the glasses. For example, a long press may turn the device  100  on or off, whereas a double or triple press may activate a voice assistant. In any embodiment, the actuation button  106  may be configured to be used in a similar manner to activate different functionalities of the glasses device  100 . In some embodiments, the actuation button  106  may be disposed on a bottom side of the temples  102 . As shown in the depicted example, the actuation button  106  may be generally circular (e.g, cylindrical) in shape, however, in any embodiment, the actuation button  106  may be square, rectangular, oval, triangular, or any other geometric shape. In some scenarios, the actuation button may utilized by a user, for example, to power the device  100  on or off, without interfering with or dislodging the safety shield members  110  from the temples  102 . 
     In accordance with embodiments of the present invention, the shield members  110  may be configured to be easily inserted or removed from the glasses  100 , for example, to support improved usage of the glasses, for example, before or after cleaning the glasses lenses disposed on the front frame member  101  of the glasses. For example, the shield members  110  may be removed to enable a user to properly clean the lenses of the glasses  100 , and then quickly and easily reattached after such a cleaning. In some examples, the protruding tabs  112  with magnet members  114  disposed thereon support the quick and easy application or removal of the safety shields  110  to the glasses temples  102 , for example, before or after lens cleanings. 
     In accordance with embodiments of the present invention, the glasses  100  may be configured to be operable while the safety shields  110  are inserted. For example, the glasses  100  may be smartglasses including wireless technology which may be operable by use of buttons which may not be interrupted by the placement of the safety shield members  110 . For example, the safety shield members  110  can be connected to or removed from smartglasses without disrupting access to or functioning of any buttons, for example, one or more actuator buttons  106  which may be disposed on the temples  100  of the glasses  100 , for example, smartglasses. Also for example, the safety shield members  100  may be connected to or removed from a bottom surface of the glasses temples  102 , without disrupting access to or functioning of any buttons, for example, one or more actuator buttons  106 , which may be disposed on the temples  102  of the smartglasses. In some examples, the placement of the receiving holes  104  disposed on the temples  102 , the placement of the protruding tabs  112  on the shield members  110  and/or the shape of the safety shield members  110 , for example, the curved shape of the shield portion  118 , may enable operation of buttons disposed on the glasses temples  102 , for example, one or more actuator buttons or smartglasses control buttons  106 , while the shield members  110  are inserted in the temples  102 . 
     In accordance with embodiments of the present invention, the shield members  110  may be configured to enhance the safety of the glasses  100  by providing a safety features to glasses  100 , for example, smartglasses, while opening an information channel, for example, an audible information channel which may be provided by the smartglasses, which may be configured to provide instructions, training, and/or accident or injury notifications or other hazard alerts during use of the smartglasses.
