Description:
TECHNICAL FIELD 
       [0001]    The present subject-matter generally relates to a goggle, and more specifically to a goggle with releasably attached lenses with aid of magnetic coupling. 
       BACKGROUND 
       [0002]    With the passage of time, goggle have changed in terms of look and functional attributes to enable a wide range of users including skiers, motor-bike riders etc. There are further developed goggles which enable the user to replace the mounted lens. Such developed goggles may have more than one viewing lens coupled together. 
         [0003]    Wearing such goggle and participating in various sports activities leads to fogging and smudges on the lens of the goggle. Conventional replaceable lens technology is difficult to manipulate, especially when the user in on the field and he/she has to replace lens with a gloved hand or dirty hand while in the field/ski slope. Such activity requires the user to remove the glove first and then change the lens or leave the field/ski slope to change the lens. This also results in a decreased peripheral viewing ability by not being able to quickly clean the (inside) of the lens of smudges or fog. Additionally, some lenses offer magnetic lens technology, but since the magnetic field and the number of magnetic points of such replaceable lens is low, this results in instances wherein such lens falls down in a process of replacing the lens by a user, or in case of a fall down by the user himself. Also, the magnetic force between the lenses may fade off due to regular wear and tear. 
         [0004]    Therefore, an enhanced user friendly goggle is needed to address the aforementioned problems.

       DETAILED DESCRIPTION 
       [0018]    In the following detailed description of the embodiments of the present subject matter, references are made to the accompanying drawings that form a part hereof, and in which are shown by way of illustration specific embodiments in which the present subject matter may be practiced. These embodiments are described in sufficient detail to enable those skilled in the art to practice the present subject matter, and it is to be understood that other embodiments may be utilized and that changes may be made without departing from the scope of the present subject matter. The following detailed description is, therefore, not to be taken in a limiting sense, and the scope of the present subject matter is defined by the appended claims. 
         [0019]    Some embodiments of this disclosure, illustrating all its features, will now be discussed in detail. The words “comprising,” “having,” “containing,” and “including,” and other forms thereof, are intended to be equivalent in meaning and be open ended in that an item or items following any one of these words is not meant to be an exhaustive listing of such item or items, or meant to be limited to only the listed item or items. 
         [0020]    It must also be noted that as used herein and in the appended claims, the singular forms “a,” “an,” and “the” include plural references unless the context clearly dictates otherwise. Although any systems and methods similar or equivalent to those described herein can be used in the practice or testing of embodiments of the present disclosure, the preferred, systems and methods are now described. 
         [0021]    As illustrated in  FIG. 1 , the lens assembly  100  comprises a lens bracket  105  which is substantially curvilinear. This substantially curvilinear shape of the lens bracket  105  allows the lens assembly  100  to wrap around at least a portion of the user&#39;s face to provide the user with an enhanced viewing range. Although, it should be appreciated that angled and flat shaped lenses may also be used in the lens bracket  105 . 
         [0022]    The lens bracket  105  has two surfaces, namely outer surface  110   a  and inner surface  110   b.  Both of the surfaces of the lens bracket may be made of any suitable synthetic plastic, which has low elasticity. The outer surface  110   a  of the lens bracket  105  has two extremities which are diverged in to two segments to accommodate more flexibility to a user. These two segments are jointly held by the central portion of the lens bracket. A slab  115  of predefined structure of porous substance is sandwiched between these two joint segments. Further, the inner surface  110   b  of the entire lens bracket  105  with these two segments is mounted over another slab  120  of same or similar porous materials of predefined structure using some adhesive substance. Inclusion of such porous materials in the lens bracket enhances physical characteristics such as air ventilation, shock endurance, flexibility etc. There is plurality of magnetic connectors  125  at the outer edge of the lens bracket  105  which accommodates a lens with effect of magnetic coupling. In this regard, the plurality of magnetic connectors  125  of the lens bracket  105  should be in in the same coplanar axis of the similar structure of the lens to be accommodated. 
         [0023]    Referring now to  FIG. 2 , which illustrates sectional view of the lens assembly  100  showing insertion of lens(s), in accordance with an embodiment of the present subject matter. The lens assembly has a series of spacing apparatus or spacer  205  in between the longitudinal edges of the lens bracket  105 . The spacing apparatus or spacer  205  of the lens bracket  105  couples to inner surface of an outer lens, for example, using an adhesive or other coupling means of the type. In an illustrative embodiment, the spacing apparatus  205  may be a foam tape or other structurally pliable material. The thickness of the spacing apparatus  205  may be about the same as the thickness of the lens bracket, allowing the inner lens to couple to the inner lens coupling surface of the spacing apparatus and to smoothly extend over portions of the lens bracket without creating substantial ridges or protrusions. 
         [0024]      FIGS. 3A and 3B  illustrate about other electronic components which may be associated with the lens assembly  100  and magnetic coupling between the lens bracket  105  and lens assembly  100 . As per one embodiment of the present invention, there is plurality of magnetic connectors  305  at the outer edge of the lens bracket  105 . These magnetic connectors  305  are placed apart in equal distance across the outer edge of the lens bracket  105 . These magnetic connectors  305  are placed on the lens bracket  105  by means of moulded welding or the like. These magnetic connectors  305  serve the purpose of lens coupling in the lens assembly  100  as male interface. 
         [0025]    In an another embodiment, one or more sensors may be placed on the lens assembly  100 . The placement of such sensors may be outer edge of the lens bracket  105 , or vicinity of the lens etc. The primary function of the sensors may be indicating the user that one or more lens of the goggle is not placed properly, indicating that the user need to clean the lens bracket  105  etc. Further, other components to support in performing the functions of sensors may also be present at the lens assembly  100 . 
         [0026]      FIG. 4A  illustrates about the magnetic coupling of a lens  400  with respect to an embodiment of the present invention. The lens  400  which is to be inserted will have plurality of coupling points  405 . These coupling points  405  may be placed apart at the outer edge of the lens  400 . These coupling points  405  are placed at the outer edge of the lens  405  by means of moulded welding or the like. These coupling points  405  are female interfaces. In operation, when a lens is put into the lens bracket  105 , the lens  400  is placed well on the top of the plurality of connectors  125  of the lens bracket  105 . It is to be mentioned that the plurality of connectors  125  of lens bracket  105  should be in same coplanar axis with that of the plurality of coupling points  405  in order to get the lens locked in the lens bracket  105  with the aid of magnetic force. In other words, it can be said that the position of connectors  125  and coupling points  405  should be in same place so that the lens can be placed in locking position with the help of coupling magnetic force. 
         [0027]      FIG. 4B  demonstrates that in order to pull out the lens from the lens bracket or change the lens from the lens bracket, a user has to hold the lens bracket with one hand and by another hand (with or without gloves) the entire lens can be held and taken out from the lens bracket. In similar fashion, a lens also can be inserted or put into the lens bracket. 
         [0028]    For example, when the user has to put a lens to enhance further vision, then the user first has to remove the lens which is in order in the lens bracket. Upon removal of the lens, the user can put the lens into the lens bracket with ease. In such a process, the outer surface of the lens bracket includes one or more magnetic connectors and which are moulded on the outer edge of the lens bracket. Similarly, the one or more coupling points on the outer edge of the lens are also moulded and have to be on the same position with magnetic connectors when placed on the lens bracket. 
         [0029]      FIGS. 5A and 5B  illustrate about placing the goggle on user&#39;s head securely. In an embodiment of the present invention, a goggle securing strap  505  may be attached to the lens assembly  100  or the lens bracket  105  to enable user to wear it around the head comfortably. Such strap may include other features, such as tension adjustment buckles, earstems that extend from the goggle to engage the sides and/or ears of a wearer, snaps, clips, hook-and-loop fasteners or other devices to secure the goggle to a helmet or other headgear, and so on. In addition to the above, in some embodiments the goggle may include adjustable arms located at the sides of the frame that the head support may be attached to. The adjustable arms may allow a user to adjust the fit of the goggle. The goggle as disclosed herein with replaceable lens may be used with any type of head support that allows the goggle to be retained on the head of an individual. Further, the strap  505  so attached may be developed to ease a user to attach/detach with the lens assembly  100  or the lens bracket  105 . Also, the strap  505  may have other suitable features such as easy slide and lock etc. to serve the purpose quickly. 
         [0030]    Although illustrative embodiments of goggle are described herein, it should be appreciated that in the development of one or more actual embodiments, numerous implementation-specific decisions may be made to achieve specific goals, for example, compliance with system-related and business-related constraints, which may vary from one implementation to another. Moreover, it should be appreciated that a development effort can be complex and time-consuming, but should nevertheless be a routine undertaking for one skilled in the art having the benefit of this disclosure.
