Patent Description:
Goggles with replaceable lenses typically include a frame and one or more removable lenses. The frame may be equipped with a mechanism for attachment of the lens. In some goggles, the lens is attached to the frame with magnets. However, in existing goggles of this kind, the lens may be easily dislodged from the frame. Additionally or alternatively, in existing goggles, removal of the lens may be unduly complex or cumbersome for a user, or may have other deficiencies which result in a suboptimal user experience. For these reasons or other reasons, improvements in goggles with removable lenses may be desired. <CIT> discloses a device for detachably fixing a lens on goggles including: a detachable fixing member having a plurality of metal pieces adapted to be insertedly fixed to a plurality of equally spaced insertion grooves formed along a frame rim and a plurality of permanent magnets adapted to be insertedly fixed to a plurality of equally spaced insertion grooves formed along a lens rim on the same line as the plurality of metal pieces insertedly fixed along the frame rim in such a manner as to be coupled and separated to and from the plurality of metal pieces; and clip members adapted to be fixed to both sides of the frame so as to rigidly fix the lens to the frame. <CIT> discloses eyewear, such as a goggle, that can include an anterior module and an interchangeable posterior module. The anterior module can be adapted to support at least one lens in a wearer's field of view. The posterior module can be adapted to fit against a contour of the wearer's face and can be selectively interchangeable with the anterior module to modify at least one physical characteristic of the eyewear.

The description will be more fully understood with reference to the following figures in which components may not be drawn to scale, which are presented as various embodiments of the eyewear and eyewear components described herein and should not be construed as a complete depiction of the scope of the present disclosure.

Examples of goggles with removable lenses are described. In some examples, the goggle may include a first retention feature (e.g., magnets) that couple a lens assembly to a goggle frame. To limit inadvertent decoupling of the lens assembly from the goggle frame, the goggle may include a second retention feature (e.g., a latch mechanism) for securing the lens assembly to the goggle frame. In some embodiments, the latch mechanism may include latch components attached to the lens assembly and the goggle frame for securing the lens assembly to the goggle frame. In some embodiments, the latch components may engage mechanically for mechanically securing the lens assembly to the goggle frame. In some embodiments, the latch mechanism may include one or more magnetic elements (e.g., magnets) for securing the lens assembly to the goggle frame. The latch mechanism may include at least one actuator for manipulation by the user to release and/or engage the latch, and at least one tab that includes engagement feature(s) which cooperate with respective engagement feature(s) on the actuatable component to engage the latch. The actuator may be coupled to the goggle frame or the lens frame. In some embodiments, the actuator is coupled to the goggle frame, for example behind an outrigger so as to at least partially conceal the actuator from view and provide a more aesthetically pleasing look of the goggle.

As shown in <FIG>, an example goggle <NUM> includes a lens assembly <NUM> removably coupled to a goggle frame <NUM>. The goggle <NUM> may be of a shield-type design including a single or unitary outer lens <NUM>, which may be configured to extend in the field of view of both the left and right eyes of the user when worn. The outer lens <NUM> may be formed from a single lens blank and may thus be devoid of any seams or other discontinuities in the lens. The outer lens <NUM> may be made from polycarbonate (PC), acrylic, or other materials which can provide suitable optical qualities (e.g., optical clarity) to the optical portion of the eyewear. The outer lens <NUM> may be rimless or frameless in that a perimeter of the lens <NUM> is not substantially enclosed by a frame, as illustrated in <FIG>. These features may provide a larger unobstructed field of view through the outer lens <NUM>.

In some embodiments, the lens assembly <NUM> may include a dual-lens structure. For example, as illustrated in <FIG>, the lens assembly <NUM> may include outer lens <NUM> and inner lens <NUM>. The lenses <NUM>, <NUM> may have a generally arcuate shape, such as cylindrical, spherical or another type of arcuate shape. The lenses <NUM>, <NUM> may comprise one or more compounds and/or coatings configured to impart light transmittance characteristics as may be desired or suitable for a particular application. For example, the lenses <NUM>, <NUM> may include one or more compounds or coatings, which configure the lenses <NUM>, <NUM> into a tinted lens, a polarized lens, a scratch resistant lens, or combinations thereof. Additionally or alternatively, the lenses <NUM>, <NUM> may be formed from a projectile- or shatter-resistant material selected to meet one or more ballistic safety standards. The lenses <NUM>, <NUM> may have a front or outward-facing surface (i.e. the side of the lenses, which is farthest away from the user's face when the eyewear is worn) and a rear or inward-facing surface (i.e. the side of the lens, which is closest to the user's face when the eyewear is worn). Compounds and/or coatings, such as for tinting the lenses <NUM>, <NUM>, may be laminated in the body of the lenses <NUM>, <NUM> and/or applied to either of the rear or front sides of the lenses <NUM>, <NUM>.

Referring still to <FIG>, the lens assembly <NUM> may include a spacer <NUM> (e.g., a foam spacer) that attaches the outer and inner lenses <NUM>, <NUM> together. The spacer <NUM> may be positioned at least partially between the outer lens <NUM> and the inner lens <NUM>, and may extend along a peripheral portion of the outer lens <NUM> and the inner lens <NUM> so as to provide a large unobstructed field of view through the outer lens <NUM> and the inner lens <NUM>. The spacer <NUM> may include adhesive on both of its sides (i.e., its front and rear surfaces) to adhere the outer lens <NUM> to the inner lens <NUM>. For example, the spacer <NUM> may be implemented using a double-sided adhesive foam tape.

With continued reference to <FIG>, the lens assembly <NUM> may include a lens frame <NUM> configured for removably coupling the lens assembly to the goggle frame <NUM>. The lens frame <NUM> may support the inner lens <NUM> and/or the spacer <NUM>. As shown in the illustrated embodiment, the lens frame <NUM> may define a seat <NUM> that receives and supports the spacer <NUM>. A rear surface of the spacer <NUM> may abut against the seat <NUM> when the lens assembly <NUM> is assembled, and adhesive applied to the rear surface of the spacer <NUM> may adhere the spacer <NUM> to the lens frame <NUM>. In some embodiments, the lens frame <NUM> is formed of polycarbonate, and may be molded. The lens frame <NUM> may thus be relatively more rigid as compared to the relatively softer portions of the goggle frame <NUM> that are positioned conformally to the user's face.

Referring to <FIG> and <FIG>, the lens frame <NUM> may be configured to extend along a peripheral portion of the inner lens <NUM> to restrict the inner lens <NUM> from delaminating or separating from the spacer <NUM>. The inner lens <NUM> may be formed of a different material than the outer lens <NUM>. For example, the inner lens <NUM> may be designed to be hydrophilic to inhibit fogging, which may reduce the effectiveness of the adhesive on the spacer <NUM>. To inhibit or reduce the risk of separation of the inner lens <NUM> and the spacer <NUM>, the lens frame <NUM> may include a lip <NUM> that extends interiorly from the seat <NUM> (see <FIG>). The lip <NUM> may abut against a rear surface <NUM> of the inner lens <NUM> (see <FIG>) around a periphery of the inner lens <NUM>. With the spacer <NUM> bonded to the seat <NUM> of the lens frame <NUM> (see <FIG>), the inner lens <NUM> may be captured or sandwiched between the spacer <NUM> and the lip <NUM> of the lens frame <NUM>, thereby inhibiting separation of the inner lens <NUM> from the spacer <NUM>. As illustrated in <FIG>, the inner lens <NUM> may be smaller in size (e.g., height and/or thickness) than the outer lens <NUM>.

As illustrated in <FIG>, the goggle <NUM> may define a nose recess <NUM> (e.g., along a bottom periphery of the lens assembly <NUM>), which may be configured to accommodate the nose of the wearer when the goggle <NUM> is worn. In some embodiments, a nose pad <NUM> may be provided at the nose recess <NUM>. The nose pad <NUM> may be formed from a soft or flexible polymeric material (e.g., thermoplastic elastomer (TPE), such as a thermoplastic polyurethane (TPU) material) which may conform to the user's nose for a comfortable fit and may optionally include one or more bendable portions for improved adjustability. The nose pad <NUM> may form part of the goggle frame <NUM> (see <FIG>), which may also be at least partially formed of a TPE, or may connect directly to the lens assembly <NUM> at the recess <NUM>. In some examples, the nose pad <NUM> may be removably attached to the lens assembly <NUM> or the goggle frame <NUM>, such as to enable replacement of the nose pad <NUM>.

The goggle <NUM> may include first and second opposite end portions <NUM>-<NUM>, <NUM>-<NUM>. A strap <NUM> (such as an elastic headband) may be attached to each of the first and second end portions <NUM>-<NUM>, <NUM>-<NUM> via first and second outriggers <NUM>-<NUM>, <NUM>-<NUM>, respectively (see <FIG> and <FIG>). Each outrigger <NUM>-<NUM>, <NUM>-<NUM> may be pivotally coupled to the goggle frame <NUM> to provide a relatively customized fit of the strap <NUM> around a front portion of a wearer's head.

In some embodiments, the lens assembly <NUM> may be a magnetically coupled to the goggle frame <NUM>. The lens assembly <NUM> and the goggle frame <NUM> may include magnetic materials (e.g., a permanent magnet such as a rare earth magnet, or ferromagnetic material such as iron or steel) for removably coupling the lens assembly <NUM> to the goggle frame <NUM>. In some embodiments, the magnetic materials may have one or more surfaces exposed (e.g., the facing surfaces of the magnets). The magnetic materials may be substantially enclosed (e.g., except for one side of the magnetic material being at least partially exposed) in pockets formed within the lens assembly and the goggle frame. The magnetic materials may be attached to opposing (e.g., facing) sides of the lens assembly <NUM> and the goggle frame <NUM> to urge the lens assembly <NUM> towards the goggle frame <NUM>. The magnetic attraction between the magnetic materials on the lens assembly <NUM> and the goggle frame <NUM> may provide a centering function (e.g., resulting from the magnetic materials natural tendency to axially align their respective fields to one another), which may facilitate alignment of the lens assembly <NUM> to the goggle frame <NUM>.

Referring to <FIG>, the goggle frame <NUM> may include magnetic materials for magnetic coupling with corresponding magnetic materials on the lens assembly <NUM>. For example, the goggle frame <NUM> may include magnets <NUM> exposed along an angled surface <NUM> of the goggle frame <NUM>. The magnets <NUM> may be arranged along a lower portion of the goggle frame <NUM> (such as generally beneath a wearer's eyes and adjacent the wearer's nose) and along an upper portion of the goggle frame <NUM> (such as adjacent a wearer's forehead). Several magnets <NUM> may be arranged adjacent the nose pad <NUM>. In the illustrated embodiment, the goggle frame <NUM> includes eight magnets <NUM>, but in other embodiments the goggle frame <NUM> may include more or less than eight magnets <NUM>. The magnets <NUM> may include an exposed surface that is substantially flush with the angled surface <NUM>, which may be angled inward and rearward toward a center of the goggle frame <NUM> to facilitate alignment of the lens assembly <NUM> with the goggle frame <NUM>. The magnets <NUM> may be oriented at about a forty-five degree angle (e.g., forty-five degrees plus or minus thirty degrees) to facilitate alignment of the lens assembly <NUM> with the goggle frame <NUM>. In some embodiments, the angled surface <NUM> and the magnets <NUM> are oriented at a forty-five degree angle relative to a plane defined by the curvature of the outer lens <NUM> to facilitate alignment of the lens assembly <NUM> with the goggle frame <NUM>. In other embodiments, different arrangement (e.g., orientation) of the magnets with respect to the surface <NUM> may be used.

Referring to <FIG>, the goggle frame <NUM> may include a face gasket and an interface component for interfacing with the removable lens assembly. The face gasket may be provided by one or more resiliently deformable components, which are configured to placed conformally to the user's face. In the embodiment in <FIG>, the face gasket is provided by a frame ring <NUM>. In some embodiments, e.g., as shown in <FIG>, the interface component is implemented as an overmold component or material <NUM>. The overmold material <NUM> may be formed of a relatively hard or rigid material (e.g., nylon) to form an interface component that provides a structural base for interfacing with the lens frame <NUM>. The face gasket (e.g., frame ring <NUM>) of the goggle frame <NUM> may be formed of a softer material (e.g., thermoplastic polyurethane (TPU)) for conformally interfacing with the wearer's face. In some embodiments, the frame ring <NUM>, which may be formed from the relatively more flexible material (e.g., TPU) for example by an injection molding process, may be overmolded by the relatively more rigid material (e.g., nylon) in an overmold process during which the interface component is shaped or formed while being joined to the frame ring. In other embodiments, the interface component(s) may be formed first and the overmolded by the face gasket material.

In some embodiments, the magnets <NUM> are inserted into pockets <NUM> defined in the frame ring <NUM>, and then the frame ring <NUM> is overmolded by the overmold material <NUM>, thereby effectively molding the magnets <NUM> into the goggle frame <NUM>. The magnets <NUM> may be attached to the frame ring <NUM>, such that the frame ring <NUM> counteracts the magnetic force imposed on the magnets <NUM> by the lens assembly <NUM> to ensure the magnets <NUM> are not pulled out of the goggle frame <NUM> during decoupling of the lens assembly <NUM> from the goggle frame <NUM>. For example, as illustrated in <FIG>, the magnets <NUM> may include wings <NUM> extending from opposing ends of the magnets <NUM>, and the wings <NUM> may be received within slots <NUM> formed in the frame ring <NUM> at opposing ends of the pockets <NUM>. The overmold material <NUM> may cover at least a front portion of the frame ring <NUM> and at least a portion of the magnets <NUM> to lock the magnets <NUM> in place (e.g., restrict the wings <NUM> of the magnets <NUM> from sliding out of the slots <NUM> in the frame ring <NUM>). At least a portion of a front surface of the magnets <NUM> may be exposed through the overmold material <NUM> to facilitate magnetic coupling of the magnets <NUM> with the lens assembly <NUM>.

Referring to <FIG> and <FIG>, the lens assembly <NUM> may include magnetic materials for magnetic coupling with corresponding magnetic materials on the goggle frame <NUM>. For example, the lens assembly <NUM> may include magnets <NUM> exposed along an angled surface <NUM> of the lens assembly <NUM>. The magnets <NUM> may be arranged at corresponding locations to the magnets <NUM> of the goggle frame <NUM>, and may include opposing polarities to the magnets <NUM> such that the magnets <NUM>, <NUM> are attracted to each other. The magnets <NUM> may include an exposed surface that is substantially flush with the angled surface <NUM>, which may be angled at a corresponding angle to the angled surface <NUM> of the goggle frame <NUM> to facilitate alignment of the lens assembly <NUM> with the goggle frame <NUM>. The magnets <NUM> may be oriented at about a forty-five degree angle (e.g., forty-five degrees plus or minus thirty degrees) to facilitate alignment of the lens assembly <NUM> with the goggle frame <NUM>. In some embodiments, the angled surface <NUM> and the magnets <NUM> are oriented at a forty-five degree angle relative to a plane defined by the curvature of the inner lens <NUM> to facilitate alignment of the lens assembly <NUM> with the goggle frame <NUM>. As illustrated in <FIG>, the magnets <NUM> may be received in pockets <NUM> defined in the lens frame <NUM>. The magnets <NUM> may only be inserted into the pockets <NUM> from a front side of the lens frame <NUM>, such that the lens frame <NUM> inhibits the magnets <NUM> from being pulled out of the lens assembly <NUM> during decoupling of the lens assembly <NUM> from the goggle frame <NUM>.

As previously described, positioning and/or alignment of the lens assembly <NUM> relative to the goggle frame <NUM> may be achieved substantially by the shape and/or contours of the corresponding contact surfaces of the lens assembly <NUM> and the goggle frame <NUM>, which in the illustrated embodiment is defined in part by the shape and wall contours of the peripheral rim of the lens assembly <NUM> and the goggle frame <NUM>. Additionally or alternatively, positioning and/or alignment of the lens assembly <NUM> with respect to the goggle frame <NUM> may be aided by the automatic centering of the magnetic interaction between the lens assembly <NUM> and the goggle frame <NUM>. In some embodiments, the lens assembly <NUM> and the goggle frame <NUM> may include corresponding alignment features to facilitate alignment of the lens assembly <NUM> to the goggle frame <NUM>. For example, as illustrated in <FIG>, the lens assembly <NUM> and the goggle frame <NUM> may include corresponding extensions and recesses to facilitate alignment of the lens assembly <NUM> and the goggle frame <NUM>. Referring to <FIG> and <FIG>, the goggle frame <NUM> may include recesses <NUM> defined in the angled surface <NUM>. The recesses <NUM> may be arranged between adjacent magnets <NUM>. Referring to <FIG> and <FIG>, the lens assembly <NUM> may include extensions <NUM> protruding from the angled surface <NUM>, and the extensions <NUM> may correspond to the locations of the recesses <NUM> defined in the goggle frame <NUM>. The extensions <NUM> may be received in the recesses <NUM> when the lens assembly <NUM> is properly aligned with the goggle frame <NUM>, and, when received in the recesses <NUM>, the extensions <NUM> may restrict lateral movement of the lens assembly <NUM> relative to the goggle frame <NUM>. In other embodiments, the recesses <NUM> may be defined in the lens assembly <NUM>, and the extensions <NUM> may be formed on the goggle frame <NUM>. In other embodiments, the length of recesses <NUM> and extensions <NUM> may be extended. The recesses <NUM> may extend along a length of the angled surface <NUM> such that they substantially span a distance between adjacent magnets <NUM> along the angled surface <NUM>. The extensions <NUM> may extend along a length of angled surface <NUM> such that they substantially span a distance between adjacent magnets <NUM>, corresponding to the locations and lengths of recesses <NUM>. Extending the lengths of the recesses <NUM> and extensions <NUM> may further facilitate alignment of the lens assembly <NUM> and the goggle frame <NUM>.

Magnetic force acting between magnetic materials positioned on opposing faces of the lens assembly <NUM> and the goggle frame <NUM> may resist separation of the lens assembly <NUM> from the goggle frame <NUM>. In some examples, the lens assembly <NUM> may additionally or alternatively be mechanically coupled to the goggle frame <NUM>. For example, the goggle <NUM> may include two or more retention features for mechanically interlocking the lens assembly <NUM> to the goggle frame <NUM>. In some examples, the lens assembly <NUM> may include latch components (e.g., protrusion, hooks, or other surface or edge features which may be operably connected to levers or other actuators for actuating the same) which may be configured to interlock with corresponding latch components of the goggle frame <NUM> such as to resist separation of the lens assembly <NUM> from the goggle frame <NUM>.

The two or more retention features of the goggle <NUM> may prevent inadvertent separation of the lens assembly <NUM> from the goggle frame <NUM>. For example, the two or more retention features may prevent the lens assembly <NUM> from being accidentally detached from the goggle frame <NUM> when the goggle <NUM> is being worn. In the absence of the retention features described herein (e.g., latches), the magnetic force between the lens assembly <NUM> and the goggle frame <NUM> may be insufficient, and the lens assembly <NUM> may pop off or disengage the goggle frame <NUM>, which would be undesirable. Using magnets that provide a sufficiently strong magnetic field to resist inadvertent detachment may not be a practical solution because this would make coupling or decoupling of the lens assembly <NUM> by the user more arduous (e.g., the user would have to apply significantly more force to remove the lens assembly <NUM>), thus detracting from the user experience. The combination of using two or more retention features (e.g., latches) and magnetic coupling to maintain the lens assembly <NUM> in engagement with the goggle frame <NUM> in accordance with the examples disclosed herein may provide a more elegant solution.

Referring to <FIG>, the goggle <NUM> may include a plurality of retention features (e.g., two or more retention features) to secure the lens assembly <NUM> to the goggle frame <NUM>. For example, as illustrated in <FIG>, the goggle <NUM> may include first and second retention features <NUM>-<NUM>, <NUM>-<NUM> at first and second locations, respectively, to resist inadvertent decoupling of the lens assembly <NUM> from the goggle frame <NUM>. The retention features <NUM>-<NUM>, <NUM>-<NUM> may be positioned anywhere around the perimeter of the goggle <NUM> (e.g., at the sides, top, bottom, etc.). The retention features <NUM>-<NUM>, <NUM>-<NUM> may be attached to the goggle <NUM> at various locations, for example at opposite (e.g., left and right) end portions <NUM>-<NUM>, <NUM>-<NUM> of the goggle <NUM>. As illustrated in <FIG>, the retention features <NUM>-<NUM>, <NUM>-<NUM> may be at least partially concealed by the first and second outriggers <NUM>-<NUM>, <NUM>-<NUM>, respectively.

Referring to <FIG>, the lens assembly <NUM> may be removable from the goggle frame <NUM> by actuating only one of the first and second retention features <NUM>-<NUM>, <NUM>-<NUM>. For example, as illustrated in <FIG>, actuation of one of the retention features (e.g., retention feature <NUM>-<NUM> in <FIG>, see arrow <NUM> in <FIG>) releases one end of the lens assembly <NUM> from the goggle frame <NUM>, allowing the lens assembly <NUM> to be pivoted away from the goggle frame <NUM> (see direction arrow <NUM> in <FIG>) about the other retention feature (e.g., retention feature <NUM>-<NUM> in <FIG>). After pivoting the lens assembly <NUM>, the wearer may grasp the free end of the lens assembly <NUM> and pull the lens assembly <NUM> away from the retention feature <NUM>-<NUM> in <FIG> to detach the lens assembly <NUM> from the goggle frame <NUM> without actuating the retention feature <NUM>-<NUM>.

In some embodiments, the retention features <NUM>-<NUM>, <NUM>-<NUM> comprise latches (also referred to as latch mechanisms). For example, as illustrated in <FIG>, the goggle <NUM> may include a first latch <NUM>-<NUM> and a second latch <NUM>-<NUM>. The latches <NUM>-<NUM>, <NUM>-<NUM> may be coupled to or proximate the end portions <NUM>-<NUM>, <NUM>-<NUM>, respectively, of the goggle <NUM>. Each latch <NUM>-<NUM>, <NUM>-<NUM> may include a first latch component <NUM> coupled to the lens assembly <NUM> and a second latch component <NUM> coupled to the goggle frame <NUM>.

With continued reference to <FIG>, the lens assembly <NUM> may include the first latch components <NUM> of the latches <NUM>-<NUM>, <NUM>-<NUM>, and each latch component <NUM> may be coupled to a respective end portion of the lens assembly <NUM>. The first latch components <NUM> may be fixedly attached to the lens assembly <NUM> which generally implies that the first latch components <NUM> are not be intended to be removed during normal use of the goggle <NUM>. For example, the first latch components <NUM> may be attached (e.g., bonded and/or mechanically secured) to the lens assembly <NUM> or may be formed integrally with the lens assembly <NUM> as a unitary structure. In the illustrated embodiment, the lens assembly <NUM> includes two separate latch components attached to the opposite ends (e.g., distal ends) of the lens assembly <NUM>, although in other embodiments the lens assembly <NUM> may include more than two latch components.

Referring still to <FIG>, the first latch components <NUM> of the latches <NUM>-<NUM>, <NUM>-<NUM> may be arranged generally along the arc length direction of the lens assembly <NUM>, which may serve aesthetic and/or utilitarian functions. In the embodiment illustrated in <FIG>, each of the first latch components <NUM> extends from one of two opposite ends of the lens assembly <NUM> in a direction generally following the curvature of the lens assembly <NUM>. The first latch components <NUM> may be arranged as an extension to the ends of the lens assembly <NUM> such that the first latch components <NUM> project at least partially from the ends of the lens assembly <NUM>, thereby providing a slimmer form factor, which may be more appealing to the user. In some cases, the slimmer form factor may enable a more compact packaging of the lens assembly <NUM>. In the embodiment in <FIG>, each of the first latch components <NUM> extends from one of two opposite ends of the lens assembly <NUM> in a direction generally following the curvature of the lens assembly <NUM>, which may facilitate connection of the lens assembly <NUM> to the goggle frame <NUM>. As illustrated in <FIG>, the first latch components <NUM> may extend rearward from the ends of the lens assembly <NUM>. The first latch components <NUM> may be formed as tabs that are fixedly attached to the lens frame <NUM> and project rearward from the lens frame <NUM>.

With continued reference to <FIG>, the second latch component <NUM> of each latch <NUM>-<NUM>, <NUM>-<NUM> may be movably coupled to the goggle frame <NUM>. For example, as illustrated in <FIG>, the second latch component <NUM> of each latch <NUM>-<NUM>, <NUM>-<NUM> may be pivotally coupled to the goggle frame <NUM>. As illustrated in <FIG>, the second latch component <NUM> may include a lever <NUM>. The lever <NUM> may be pivoted about a fulcrum (e.g., post <NUM>) and may include a latch feature at the end of the lever opposite the actuation (or user-engagement) end of the lever. The lever <NUM> may be configured to be provided between a latched and unlatched position such as by moving (e.g., pivoting) the lever relative to the goggle frame <NUM> from a latched position, in which the latch <NUM>-<NUM>, <NUM>-<NUM> is configured to retain the lens assembly <NUM> to the goggle frame <NUM>, to an unlatched position, in which the lens assembly <NUM> may be removed from the goggle frame <NUM>. In some embodiments, the second latch components <NUM> of each latch <NUM>-<NUM>, <NUM>-<NUM> may be pivotally coupled to the goggle frame <NUM> using a common pivot axis for the outriggers <NUM>-<NUM>, <NUM>-<NUM>, thereby providing a more compact design. As illustrated in <FIG> and <FIG>, the second latch components <NUM> and the outriggers <NUM>-<NUM>, <NUM>-<NUM> may pivot about a common post <NUM>.

As described, each retention feature <NUM>-<NUM>, <NUM>-<NUM> may include a latch component <NUM> (e.g., lever <NUM>) and a tab <NUM> coupled to respective ones of the lens assembly <NUM> and the goggle frame <NUM>. In the illustrated embodiment, the lever <NUM> is pivotally coupled to the goggle frame <NUM> and the tab <NUM> is fixedly coupled to the lens assembly <NUM> to allow the lever <NUM> to pivot away from the tab <NUM> while sliding the tab <NUM> past the lever during coupling and decoupling of the lens assembly <NUM> to the goggle frame <NUM>. In other embodiments, the position of the lever <NUM> and the tab <NUM> may be reversed, for example the lever <NUM> may be pivotally coupled to the lens assembly <NUM> and the tab <NUM> may be coupled to the goggle frame <NUM>.

The goggle frame <NUM> may include one or more features that restrict movement of the lever <NUM> in one or more directions. For example, the goggle frame <NUM> may be configured to restrict translational movement of the lever <NUM> such that the lever <NUM> is restricted to pivotal motion. As previously discussed, the lever <NUM> may be pivoted about the post <NUM>, which restricts movement of the lever <NUM> lateral to the post <NUM>. Referring to <FIG>, the goggle frame <NUM> may include one or more walls that restrict axial movement of the lever <NUM>. The one or more walls may include a lower wall <NUM>, which may restrict downward movement of the lever <NUM> (e.g., movement toward the lower peripheral edge of the lens assembly <NUM>), and an upper wall <NUM>, which may restrict upward movement of the lever <NUM> (e.g., movement toward the upper peripheral edge of the lens assembly <NUM>). As such, the lower and upper walls <NUM>, <NUM> of the goggle frame <NUM> may restrict movement of the lever <NUM> axially along the post <NUM>. As illustrated in <FIG>, a fulcrum portion <NUM> of the lever <NUM> may fit between the lower and upper walls <NUM>, <NUM> and may receive the post <NUM> via an aperture <NUM>. The outriggers <NUM>-<NUM>, <NUM>-<NUM> may extend beneath the lower wall <NUM> and above the upper wall <NUM> and may receive the post <NUM> therein, such that levers <NUM> and outriggers <NUM>-<NUM>, <NUM>-<NUM> pivot about the same posts <NUM>. In some embodiments, the goggle frame <NUM> may include a vertical wall <NUM>, which may restrict pivotal movement of the lever <NUM> (e.g., pivotal movement about the post <NUM>).

In some embodiments, the latch component <NUM> may be configured such that it returns to its closed or latched position after the lens assembly <NUM> has been attached or detached from the goggle frame <NUM>. For example, the lever <NUM> may be biased toward its latched position. Referring to <FIG>, when the lever <NUM> is pivoted toward an unlatched position, one or more arms <NUM> of the lever <NUM> may abut against the vertical wall <NUM> of the goggle frame <NUM> such that continued pivotal motion of the lever <NUM> resiliently deforms the one or more arms <NUM> and creates a preload in the one or more arms <NUM> that biases the lever <NUM> toward its latched position. By maintaining a preload in the one or more arms, the lever <NUM> is able to automatically snap back to the latched position without the application of user force. Although the one or more arms <NUM> are shown as extending substantially perpendicular to a length of the lever <NUM> (e.g., vertically) of the latch component <NUM>, in some embodiments, such as the one shown in <FIG>, the one or more arms <NUM> may extend in a direction parallel to or substantially parallel to the length of the lever <NUM> (e.g., horizontally). The embodiment shown in <FIG> may provide a more vertically compact design whereas the embodiment shown in <FIG> may provide a more horizontally compact design. In other embodiments, the biasing feature may be implemented in a different manner, for example by spring loading the lever <NUM>, by using magnetic force, or using a different combination of structural elements to restrain pivotal movement of the lever <NUM>.

Each latch <NUM>-<NUM>, <NUM>-<NUM> may be configured to cause the lever <NUM> to temporarily move (e.g., pivot) away from the tab <NUM> during attachment of the lens assembly <NUM> to the goggle frame <NUM>. For example, the lever <NUM> and/or the tab <NUM> may include ramp features which may cooperate to cause the lever <NUM> of each latch <NUM> to move from its latched position to its unlatched position as the lens assembly <NUM> is advanced toward the goggle frame <NUM>, e.g., without the application of user force to the lever <NUM> other than the force applied to advance the lens assembly <NUM> toward the goggle frame <NUM>.

In some embodiments, the inner surface of the lever <NUM> may taper outwardly towards a forward end of the lever <NUM> defining a ramp <NUM> (see <FIG>). The ramp <NUM> may be inclined such that the thickness of the lever <NUM> increases from the forward end of the lever <NUM> toward its pivot axis. The ramp <NUM> may cooperate with a ramp <NUM> on the tab <NUM> to facilitate automatic movement of the lever <NUM> from a latched position to an unlatched position during coupling of the lens assembly <NUM> to the goggle frame <NUM>. The ramps <NUM>, <NUM> may bear against each other as the lens assembly <NUM> is advanced toward the goggle frame <NUM> to cause the lever <NUM> to pivot out of its latched position against a force that biases the lever <NUM> towards its latched position.

The ramp <NUM> on the tab <NUM> may be defined on a side of the tab <NUM> (e.g., an outward-facing side) which faces the ramp <NUM> when the lens assembly <NUM> is positioned for coupling to the goggle frame <NUM>. The ramp <NUM> may guide the ramp <NUM> on the lever <NUM> as the lens assembly <NUM>, and thus the tab <NUM>, is moved toward the goggle frame <NUM> to temporarily urge the lever <NUM> away from the tab <NUM>. The ramp <NUM> may be inclined such that the lever <NUM> continues to pivot away from its latched position until the lens assembly <NUM> is magnetically coupled with the goggle frame <NUM>, at which point the ramp <NUM> may pass by the ramp <NUM> such that the biased lever <NUM> is automatically pivoted back to its latched position to restrict inadvertent decoupling of the lens assembly <NUM> from the goggle frame <NUM>. When the lever <NUM> is in the latched position, a ledge <NUM> on the lever <NUM> may be positioned behind a shoulder <NUM> on the tab <NUM> (see <FIG> and <FIG>) to inhibit removal of the tab <NUM> from the lever <NUM>, and thus the lens assembly <NUM> from the goggle frame <NUM>, until the lever <NUM> is pivoted from its latched position to its unlatched position by a wearer of the goggle <NUM>.

The tab <NUM> may be a generally plate-like structure with a barbed rearward end <NUM> as in the illustrated embodiment in <FIG>. The tab <NUM> may be angled or rounded at its rearward end <NUM> (e.g., having a generally semi-circular or semi-ovular shape at its rearward end) to define the ramp <NUM>. Although the tab <NUM> is described generally as plate like, this does not imply that the tab <NUM> is necessarily of constant thickness. While the tab <NUM> may have a constant thickness in some embodiments, in other embodiments, the tab's forward end <NUM> may include varying thickness along its length, as illustrated in <FIG> in which the forward end <NUM> of the tab <NUM> increases in thickness near its attachment to the lens frame <NUM>. Also, it will be understood that the tab <NUM> need not have a perimeter that defines a regular shape. The perimeter of the tab <NUM> may define any irregular shape as may be suitable for a particular application. The tab <NUM> may be differently shaped in other embodiments than the examples specifically illustrated or described.

The latch component <NUM> (e.g., lever <NUM>) may include a user-engagement portion <NUM> and a latch portion <NUM> as in the illustrated embodiment in <FIG>. The user-engagement portion <NUM> may be a generally plate-like structure configured for a wearer to press against to actuate the latch component <NUM> (e.g., move the lever <NUM> from its latched position to its unlatched position to enable removal of the lens assembly <NUM> from the goggle frame <NUM>). The latch portion <NUM> may be angled or rounded at its forward end to define the ramp <NUM>. The user-engagement portion <NUM> may be separated from the latch portion <NUM> by the fulcrum portion <NUM>, which may define the aperture <NUM> for receiving the pivot pin or post <NUM>. In some embodiments, as can be seen in <FIG>, the aperture <NUM> may not fully enclose post <NUM> and include a gap <NUM>. The fulcrum portion <NUM> may be formed of a resilient material and gap <NUM> may be sized such that the fulcrum portion <NUM> may be snap fit onto post <NUM>. This may provide for easier assembly of the goggle frame <NUM>. Although the user-engagement portion <NUM> is described generally as plate like, this does not imply that the user-engagement portion <NUM> is necessarily of constant thickness. The lever <NUM> may be differently shaped in other embodiments than the examples specifically illustrated or described. In some embodiments, such as the one shown in <FIG>, the user-engagement portion <NUM> may include a grip feature <NUM>. In some embodiments, the grip feature <NUM> may be a raised pattern as shown in <FIG>. In other embodiments, the grip feature <NUM> may be implemented as one or more depressions in the user-engagement portion <NUM>. The grip feature <NUM> may improve a user's grip on the user-engagement portion <NUM>.

With reference to <FIG>, sequences for coupling and decoupling the lens assembly <NUM> to the goggle frame <NUM> in accordance with some examples are described in further detail below. <FIG> show a sequence for attaching the lens assembly <NUM> to the goggle frame <NUM>. As shown in <FIG>, the lens assembly <NUM> is moved towards the goggle frame <NUM> (see direction arrow <NUM>). As the lens assembly <NUM> advances toward the goggle frame <NUM>, the tab <NUM> moves towards the lever <NUM>. When the lens assembly <NUM> is positioned sufficiently close to the lever <NUM>, the tab <NUM> may engage the lever <NUM>, for example by engaging its ramp <NUM> (see <FIG>) with the ramp <NUM> defined on the lever <NUM>. As described, the tab <NUM> and the lever <NUM> may be configured to allow the tab <NUM> to slide along the ramp <NUM> of the lever <NUM>. As the lens assembly <NUM> advances further toward the goggle frame <NUM>, e.g., as shown in <FIG>, the tab <NUM> may pivot the lever <NUM> toward an unlatched position, as shown by arrow <NUM> in <FIG>. By automatically, it is generally implied that the pivoting of the lever <NUM> from its latched position to its unlatched position occurs without the application of user force pivot the lever <NUM> but rather as the result of the cooperation of components of the latch (e.g., the cooperation of the tab <NUM> and the lever <NUM>).

As the user continues to move the lens assembly <NUM> towards the goggle frame <NUM>, the ramp <NUM> on the tab <NUM> (see <FIG>) passes over the ramp <NUM> on the lever <NUM>. Once the ramp <NUM> of the lever <NUM> has cleared the ramp <NUM> on the tab <NUM>, the lever <NUM> automatically pivots (opposite the direction of arrow <NUM> in <FIG>) into its latched position, as shown in <FIG>. In this position, the lens assembly <NUM> is not removable from the goggle frame <NUM> unless a user actuates one of the latches <NUM>-<NUM>, <NUM>-<NUM>. The return of the lever <NUM> from the unlatched position to the latched position is automatic (e.g., responsive to the biasing force, which acts in the direction opposite arrow <NUM> in <FIG>) and without further application of user force. In this manner, a latching mechanism as described herein may enable the near effortless coupling of the lens assembly <NUM> to the goggle frame <NUM>, e.g., without requiring the user to perform a complex sequence of opening and closing the latches <NUM>-<NUM>, <NUM>-<NUM>. All the user may be required to do is move the lens assembly <NUM> close to the goggle frame <NUM>, and the magnetic materials of the lens assembly <NUM> and the goggle frame <NUM> cooperate with one another to magnetically couple the lens assembly <NUM> to the goggle frame <NUM>, which movement causes the lever <NUM> to open and close, thereby securing the lens assembly <NUM> to the goggle frame <NUM>. As the lever <NUM> returns to the latched position, the extensions <NUM> and recesses <NUM> (see <FIG>) may facilitate the proper alignment and positioning of the lens assembly <NUM> to the goggle frame <NUM>.

To detach the lens assembly <NUM> from the goggle frame <NUM>, the user applies a force on one of the levers <NUM> as shown by arrow <NUM> in <FIG> to pivot the lever <NUM> about the post <NUM> (see e.g., <FIG>) away from the tab <NUM>, allowing the tab <NUM> to slide out of the goggle frame <NUM> in the direction generally opposite the direction of insertion to remove the respective end of the lens assembly <NUM> from the goggle frame <NUM>. The outriggers <NUM>-<NUM>, <NUM>-<NUM> may be prevented from inadvertently actuating the levers <NUM>, thereby inhibiting inadvertent detachment of the lens assembly <NUM> from the goggle frame <NUM>. For example, as illustrated in <FIG>, each outrigger (e.g., outrigger <NUM>-<NUM> illustrated in <FIG>) may engage a stop <NUM> formed on the goggle frame <NUM> that prevents the outriggers (see outrigger <NUM>-<NUM> in <FIG>) from pivotal movement towards the lever <NUM>, thereby inhibiting the outriggers <NUM>-<NUM>, <NUM>-<NUM> from actuating the levers <NUM>.

As previously described, the biasing feature may enable the automatic return of the lever <NUM> to its latched position once the lever <NUM> has cleared the distal end of the tab <NUM>. After one of the ends of the lens assembly <NUM> is detached from the goggle frame (see <FIG>), the wearer may grasp the free end <NUM> of the lens assembly <NUM> and move the lens assembly <NUM> in a lateral direction (see arrow <NUM> in <FIG>) away from the engaged latch <NUM>-<NUM> to remove the lens assembly <NUM> from the goggle frame <NUM>. As illustrated in <FIG> and <FIG>, moving the lens assembly <NUM> in the lateral direction (see arrow <NUM> in <FIG>) allows removal of the tab <NUM> from behind the lever <NUM> without actuating the lever <NUM>. In this manner, the lens assembly <NUM> may be detached from the goggle frame <NUM> by actuation of only one of the latches <NUM>-<NUM>, <NUM>-<NUM>. In other words, the wearer may manually actuate one of the latches <NUM>-<NUM>, <NUM>-<NUM> on one side of the goggle <NUM>, pivot the lens assembly <NUM> about the other, non-actuated latch <NUM>-<NUM>, <NUM>-<NUM> on the other side of the goggle <NUM> until the other latch disengages itself naturally without having to actuate the latch. To naturally disengage the other latch, the lens assembly <NUM> may be pivoted until all of the extensions <NUM> are removed from the recesses <NUM> (see <FIG>) and then may be laterally removed from the goggle frame <NUM>. In some embodiments, the lens assembly <NUM> is pivoted about twenty to thirty degrees to naturally disengage the other latch. The pivotal range may vary depending on the specific goggle application.

As can be seen in <FIG> and <FIG>, when lens assembly <NUM> is coupled to goggle frame <NUM>, at least a portion of the latch component <NUM> is positioned between the outer lens <NUM> and tab <NUM>. The latch component <NUM> may be arranged such as to reduce the risk of contact with the lens, e.g., by limiting the rotation of the lever <NUM>. In some embodiments, contact between the latch component <NUM> and outer lens <NUM> may be avoided by arranging the tab <NUM> such that it extends sufficiently laterally outward from the outer lens <NUM> thereby positioning the latch component <NUM> in a manner in which its actuation does not risk it contacting the lens. In some embodiments, providing at least a portion of the latch component <NUM> between the outer lens <NUM> and tab <NUM> may reduce the risk of lever <NUM> being in advertently actuated by an object near the edge of the goggle <NUM> (e.g., catching on a wearer's hood or helmet strap). Providing at least a portion of latch component <NUM> between the outer lens <NUM> and tab <NUM> may serve an aesthetic purpose of at least partially obscuring the latch component <NUM> from view. As can be seen in <FIG>, the tab <NUM> may be coupled to the lens assembly <NUM> such that tab <NUM> does not contact outer lens <NUM>.

As described, the user engagement portion of the lever <NUM> may pivot outward in a direction away from the lens assembly <NUM> during coupling of the lens assembly <NUM> to the goggle frame <NUM>. In other embodiments, this functionality may be reversed, with the user engagement portion of the lever <NUM> pivoting inward in a direction towards the lens assembly during coupling of the lens assembly <NUM> to the goggle frame <NUM>. As will be appreciated, the combination of components described herein may facilitate a virtually effortless attachment and detachment of the lens assembly <NUM> to the goggle frame <NUM>, which may provide a better user experience. The near effortless engagement of the lens assembly <NUM> to the goggle frame <NUM> in accordance with the present disclosure may enable the user to install and remove the lens assembly <NUM> without touching the lens surface (that is by only handling the lens assembly <NUM> by its edges), which may address some shortcomings of existing interchangeable goggle designs.

The lens assembly <NUM> may include multiple user engagement features located around a periphery of the lens (e.g., outer lens <NUM> and/or inner lens <NUM>) for a wearer to grasp during coupling or decoupling of the lens assembly <NUM> to or from, respectively, the goggle frame <NUM>, thus avoiding touching the lens. For example, as illustrated in <FIG> and <FIG>, the lens assembly <NUM> may include multiple rim portions <NUM> located around a periphery of the outer lens <NUM>. The rim portions <NUM> may protrude outwardly from the outer lens <NUM> such that the rim portions <NUM> form a semi-rimless frame around the periphery of the outer lens <NUM> for a wearer to grasp during coupling or decoupling of the lens assembly <NUM> to or from, respectively, the goggle frame <NUM>. The rim portions <NUM> may be located near the corners of the lens assembly <NUM> to facilitate handling of the lens assembly <NUM> by the wearer. For example, as illustrated in <FIG>, a first rim portion <NUM>-<NUM> and a fourth rim portion <NUM>-<NUM> may be located at opposing corners of one end- or side-portion of the lens assembly <NUM>, and a second rim portion <NUM>-<NUM> and a third rim portion <NUM>-<NUM> may be located at opposing corners of the other end- or side-portion of the lens assembly <NUM>. During use, the wearer may grasp the first and fourth rim portions <NUM>-<NUM>, <NUM>-<NUM> and/or the second and third rim portions <NUM>-<NUM>, <NUM>-<NUM> to manipulate the lens assembly <NUM>, such as to pivot one end of the lens assembly <NUM> away from the goggle frame <NUM> during removal of the lens assembly <NUM> from the goggle frame <NUM>. The rim portions <NUM> may be formed on the lens frame <NUM> (see <FIG>) and may protrude outwardly and forwardly from the lens frame <NUM> such that the rim portions <NUM> extend over a perimeter edge of the outer lens <NUM>, thereby ensuring the wearer does not inadvertently touch the outer lens <NUM> while grasping the tabs <NUM>. Although the lens assembly <NUM> illustrated in <FIG> and <FIG> includes four rim portions <NUM>-<NUM>, <NUM>-<NUM>, <NUM>-<NUM>, <NUM>-<NUM> (generally referred to as rim portions <NUM>), the lens assembly <NUM> may include more or less than four rim portions. The lengths of the rim portions <NUM> along the periphery of the outer lens <NUM> may be longer or shorter than the rim portions <NUM> in the example shown in <FIG>.

<FIG> illustrate a retention feature <NUM> in accordance with further embodiments of the present disclosure. The retention feature <NUM> may include a first latch component (e.g., a gate <NUM>) and a second latch component (e.g., strips <NUM>). The gate <NUM> may include (e.g., be formed at least partially of) a magnetic material (e.g., a permanent magnet such as a rare earth magnet, or ferromagnetic material such as iron or steel). Each strip <NUM> may include a magnet <NUM> (e.g., a magnetic material such as iron or a neodymium or other type of permanent magnet) affixed thereto, forming magnetic strips <NUM>. Each magnet <NUM> may have the same polarity as each other such that the magnets <NUM> are configured to repel each other to maintain the strips <NUM> in a spaced-apart relationship defining a gap <NUM> therebetween. When the gate <NUM> is inserted between the strips <NUM> during coupling of the lens assembly <NUM> to the goggle frame <NUM> (see direction arrow <NUM> in <FIG> and <FIG>), the gate <NUM> blocks the repelling force of the strips <NUM>, and the magnetic strips <NUM> are magnetically attracted to the gate <NUM> (see <FIG>) to secure the lens assembly <NUM> to the goggle frame <NUM>. In some embodiments, the second latch component may include a first magnetic strip <NUM> and the second magnetic strip <NUM> is built into goggle frame <NUM>.

<FIG> illustrate a goggle <NUM> in accordance with the principles of the present disclosure. As seen in <FIG>, goggle <NUM> may include goggle frame <NUM>, which may be coupled to lens assembly <NUM> to form goggle <NUM>. As will be described further below, goggle frame <NUM> may couple to lens assembly <NUM> in a similar manner as goggle frame <NUM>. Goggle <NUM> may include first and second opposite end portions <NUM>-<NUM> and <NUM>-<NUM>. First and second outriggers <NUM>-<NUM> and <NUM>-<NUM> may be fixedly or pivotally coupled to the goggle frame <NUM> to provide an attachment mechanism for a strap (not shown in <FIG>), such as strap <NUM> in <FIG>.

The goggle frame <NUM> in the example in <FIG> includes a face gasket, which in this example is provided by two partial frame rings, specifically upper frame ring <NUM>-<NUM> and lower frame ring <NUM>-<NUM>. The goggle frame <NUM> also include an interface component, which is provided by two side portions, specifically the first and second side portions <NUM>-<NUM> and <NUM>-<NUM>, respectively. The partial frame rings <NUM>-<NUM> and <NUM>-<NUM> and side portions <NUM>-<NUM> and <NUM>-<NUM> may reduce the weight of the goggle frame <NUM> compared to goggle frame <NUM>. Additionally, different size goggle frames may be more easily manufactured (without needing differently sized molds for the frame ring) by using different length side portions with the same upper and lower frame rings, which can improve the manufacturability of the goggle. The partial frame rings <NUM>-<NUM> and <NUM>-<NUM> may be formed of a relatively soft material (e.g., a thermoplastic elastomer such as TPU), which may allow the partial frame rings <NUM>-<NUM> and <NUM>-<NUM> to more closely and comfortably conform to a user's face. The side portions <NUM>-<NUM> and <NUM>-<NUM> may be formed of a harder or more rigid material (e.g., a rigid plastic such as nylon), thereby providing a stable base or interface for coupling the removable lens assembly <NUM> to the goggle frame <NUM>.

In some embodiments, side portions <NUM>-<NUM> and <NUM>-<NUM> may be coupled to upper frame ring <NUM>-<NUM> and lower frame ring <NUM>-<NUM> by an overmolding process. In an example manufacturing process, the side portions <NUM>-<NUM> and <NUM>-<NUM> are formed (e.g., by injection molding, compression molding or other suitable molding process or via an additive manufacturing process such as stereolithography (SLA) or other 3D printing process). After the side portions are formed into the suitable rigid plastic material (e.g., cured nylon, resin or another), the side portions are inserted into a mold tool where they are overmolded with the thermoplastic elastomer (e.g., TPU) of the face gasket. As described further herein, the magnets may then be inserted into pockets of the frame gasket. In other examples, the magnets may be insert molded with the face gasket (i.e., the magnets are appropriately positioned in the mold tool before the addition of the thermoplastic elastomer such that they may affix to the face gasket during the curing process. In further examples (e.g., which can apply to the goggle embodiment in <FIG>, the manufacturing sequence may involve forming the interface component (e.g., frame ring) first such by injection molding or other suitable process, then inserting the magnets into magnet seats in the interface components, and overmolding with the face gasket material to sandwich and thereby secure the magnets to the goggle frame. In yet other examples, the manufacturing sequence may not involve any overmolding. That is, the face gasket component(s) and the interface component(s) may be each separately formed via a suitable process such as molding or additive manufacturing and the two separately formed components may be attached to one another via an adhesive and/or mechanical coupling (e.g., fasteners, snap features, etc.).

Referring to <FIG>, the partial frame rings <NUM>-<NUM> and <NUM>-<NUM> may include one or more protrusions <NUM> at end portions <NUM>-<NUM> and <NUM>-<NUM> configured to engage cavities <NUM> formed in the side portions <NUM>-<NUM> and <NUM>-<NUM>. In some embodiments, such as those shown in <FIG>, the protrusions <NUM> may have a hook-like structure which may provide additional retention of the side portions <NUM>-<NUM> and <NUM>-<NUM> to the partial frame rings <NUM>-<NUM> and <NUM>-<NUM>.

Referring to <FIG>, lower frame ring <NUM>-<NUM> may include a nose pad <NUM> which may be configured to accommodate the nose of a wearer when the goggle <NUM> is worn. The nose pad <NUM> may be formed of the same material as the rest of the lower frame ring <NUM>-<NUM>. In some embodiments, an additional material (not shown) may be coupled to a surface of nose pad <NUM> adjacent to the nose of the wearer when worn. The additional material may be a soft or flexible polymeric material (e.g., foam) which may further conform to the user's nose for a comfortable fit and provide additional cushioning.

Referring to <FIG>, upper frame ring <NUM>-<NUM> and lower frame ring <NUM>-<NUM> may include holes <NUM> near end portions <NUM>-<NUM> and <NUM>-<NUM> configured to receive prongs <NUM> of outriggers <NUM>-<NUM> and <NUM>-<NUM>. The prongs <NUM> may retain outriggers <NUM>-<NUM> and <NUM>-<NUM> to the partial frame rings <NUM>-<NUM> and <NUM>-<NUM>. In some embodiments, the prongs <NUM> may rotate within holes <NUM>, pivotally coupling the outriggers <NUM>-<NUM> and <NUM>-<NUM> to the goggle frame <NUM>. In other embodiments, the prongs <NUM> may be configured to engage holes <NUM> such that the outriggers <NUM>-<NUM> and <NUM>-<NUM> are fixedly attached to the partial frame rings <NUM>-<NUM> and <NUM>-<NUM>.

Returning to <FIG>, partial frame rings <NUM>-<NUM> and <NUM>-<NUM> may have angled surfaces <NUM>-<NUM> and <NUM>-<NUM>. Angled surfaces <NUM>-<NUM> and <NUM>-<NUM> may be angled inward and rearward toward a center of the goggle frame <NUM> to facilitate alignment of the lens assembly <NUM> with the goggle frame <NUM>. In some embodiments, the angled surfaces <NUM>-<NUM> and <NUM>-<NUM> may be oriented at a forty-five degree angle relative to a plane defined by the curvature of the outer lens <NUM> to facilitate alignment of the lens assembly <NUM> with the goggle frame <NUM>. The angled surfaces <NUM>-<NUM> and <NUM>-<NUM> may define recesses <NUM>. The recesses <NUM> may be positioned and shaped to correspond with extensions <NUM> of lens assembly <NUM>. In other embodiments, the goggle frame <NUM> may include extensions and the lens assembly <NUM> may include recesses. The corresponding recesses and extensions may facilitate alignment between goggle frame <NUM> and lens assembly <NUM>.

Referring to <FIG> and <FIG>, similar to goggle frame <NUM>, goggle frame <NUM> may include magnetic materials (e.g., magnetic elements) for magnetic coupling with corresponding magnetic materials on the lens assembly <NUM>. For example, partial frame rings <NUM>-<NUM> and <NUM>-<NUM> may include magnets <NUM> exposed along angled surfaces <NUM>-<NUM> and <NUM>-<NUM>. The magnets <NUM> may be positioned to correspond to the positions of magnets <NUM> on lens assembly <NUM>. The magnets <NUM> may have polarities opposite those of magnets <NUM> to facilitate coupling of lens assembly <NUM> and goggle frame <NUM>. In some embodiments, the magnets <NUM> may have a trapezoidal shape surface. Pockets <NUM> may be defined in the upper and lower frame rings <NUM>-<NUM> and <NUM>-<NUM> along angled surfaces <NUM>-<NUM> and <NUM>-<NUM> between adjacent recesses <NUM>. The pockets <NUM> may have a generally trapezoidal shape oriented such that the opening of the pockets <NUM> at the angled surfaces <NUM>-<NUM> and <NUM>-<NUM> are smaller than the bottoms of the pockets <NUM>. The shape of the pockets <NUM> may correspond to the trapezoidal shape of the magnets <NUM> such that the magnets <NUM> are retained in the pockets <NUM> and exposed surfaces of the magnets <NUM> are flush with the angled surfaces <NUM>-<NUM> and <NUM>-<NUM>. In some embodiments, the partial frame rings <NUM>-<NUM> and <NUM>-<NUM> may be temporarily deformed (e.g., bent) such that the opening to the pockets <NUM> are widened. The magnets <NUM> may be placed inside the pockets <NUM> during deformation and once the partial frame rings <NUM>-<NUM> and <NUM>-<NUM> are returned to their original shapes, the magnets <NUM> may be retained within the pockets <NUM>. In some embodiments, an adhesive may be applied inside the pockets <NUM> to provide additional retention of the magnets <NUM> in the pockets <NUM>. Although goggle frame <NUM> is shown including seven magnets <NUM> in <FIG>, it is understood that goggle frame <NUM> may include more or fewer magnets <NUM> in other embodiments.

Similar to goggle frame <NUM>, goggle frame <NUM> may include additional retention features to secure lens assembly <NUM> to the goggle frame <NUM>. For example, as illustrated in <FIG>, goggle frame <NUM> may include retention features <NUM>-<NUM> and <NUM>-<NUM> located at side portions <NUM>-<NUM> and <NUM>-<NUM>. As illustrated in <FIG>, the retention features <NUM>-<NUM> and <NUM>-<NUM> may be at least partially concealed by outriggers <NUM>-<NUM> and <NUM>-<NUM>, respectively.

In some embodiments, the retention features <NUM>-<NUM> and <NUM>-<NUM> may comprise latches. For example, as illustrated in <FIG>, the goggle <NUM> may include a first latch <NUM>-<NUM> and second latch <NUM>-<NUM>. The latches <NUM>-<NUM> and <NUM>-<NUM> may be coupled to or proximate the side portions <NUM>-<NUM> and <NUM>-<NUM>, respectively. Each latch <NUM>-<NUM> and <NUM>-<NUM> may include a first latch component <NUM> coupled to the lens assembly <NUM>. That is, portion of the latch included with the lens assembly <NUM> may be the same as the latch component <NUM> described in reference to <FIG> and <FIG> in some embodiments (e.g., tab <NUM>). Each latch <NUM>-<NUM> and <NUM>-<NUM> may further include a second latch component <NUM> coupled to the goggle frame <NUM>. That is, the second latch component <NUM> may be the same as the latch component <NUM> shown in <FIG> and <FIG> in some embodiments. In other embodiments, component <NUM> may be the same as the latch component <NUM> illustrated in <FIG>. In the examples described in reference to <FIG>, <FIG> and <FIG>, the latch component <NUM> of <FIG> is shown.

With reference to <FIG> and <FIG>, the second latch component <NUM> of each latch <NUM>-<NUM> and <NUM>-<NUM> may be movably coupled to the goggle frame <NUM> at side portions <NUM>-<NUM> and <NUM>-<NUM>, respectively. Side portions <NUM>-<NUM> and <NUM>-<NUM> may each include a post <NUM>. For convenience, reference will be made only one of the side portions, but it should be understood that equivalent elements and arrangement of elements may be present on both side portions <NUM>-<NUM> and <NUM>-<NUM> in some embodiments. As shown in <FIG>, the aperture <NUM> may be configured to receive post <NUM> pivotally coupling the latch component <NUM> to the side portion <NUM>. The post <NUM> may restrict movement of the latch component <NUM> lateral to the post <NUM>. The side portion <NUM> may include lower wall <NUM> and upper wall <NUM> on opposite ends of the post <NUM>. The lower wall <NUM> and upper wall <NUM> may restrict the up and down movement of the latch component <NUM>. In some embodiments, side portion <NUM> may include side wall <NUM> which may restrict pivotal movement of the latch component <NUM> and/or provide a base for arms <NUM> to apply a biasing force. In some embodiments, portions of the partial frame rings <NUM> may be adjacent to the side wall <NUM> of the side portion <NUM>. In some embodiments, a portion of the arms <NUM> of the latch component <NUM> may apply a biasing force against the portions of the partial frame rings <NUM> adjacent to side wall <NUM>.

Referring to <FIG> and <FIG>, side portion <NUM> may include stops <NUM>. In some embodiments, such the embodiment illustrated in <FIG>, stops <NUM> are in the form of flanges that angle outward from goggle frame <NUM>. As shown in <FIG>, the outrigger <NUM> may include recesses <NUM> having shapes corresponding to stops <NUM>. The stops <NUM> may restrict pivotal movement of outrigger <NUM> to prevent the outrigger <NUM> from actuating latch component <NUM> when the outrigger <NUM> is pivotally attached. When the outrigger <NUM> is fixedly attached to the goggle frame <NUM>, the stops <NUM> may space the outrigger <NUM> from the latch component <NUM> and restrict inadvertent rotation of the outrigger <NUM> due to impact or other forces on the goggle frame <NUM>. This may prevent inadvertent disengagement of lens assembly <NUM> from goggle frame <NUM>.

Unlike the embodiment of google frame <NUM>, the outrigger <NUM> and latch component <NUM> do not share a common attachment point and/or pivotal axis in the embodiment of goggle frame <NUM>. As shown in <FIG>, the outrigger <NUM> includes a vertical panel <NUM> for coupling to a strap (not shown) with arms <NUM> extending from either end of the vertical panel <NUM>. The arms may include the prongs <NUM> described previously that allow the outrigger to be fixedly or pivotally coupled to the partial frame rings <NUM>. The pivotal axis of the latch component <NUM> is near an end portion <NUM> of the goggle <NUM>, whereas the attachment point and/or pivotal axis of the outrigger <NUM> is closer to a central point <NUM> of the arc of the goggle <NUM> as shown in <FIG>. The separate pivotal axes may further reduce interference of the outrigger <NUM> with the latch component <NUM>.

The process of coupling and decoupling goggle frame <NUM> and lens assembly <NUM> may be equivalent to the sequence described in reference to <FIG>.

Similar to the arrangement of latches <NUM> shown in in <FIG> and <FIG>, as seen in <FIG>, when lens assembly <NUM> is coupled to goggle frame <NUM>, at least a portion of the latch component <NUM> is positioned between the outer lens <NUM> and latch component <NUM>. As in <FIG>, latch component <NUM> may be positioned to avoid contacting outer lens <NUM>.

The lens assembly <NUM> and the goggle frame <NUM> may be formed of a variety of materials, for example metal, plastic (e.g., injection molded or laminated plastic materials), composite materials, or combinations thereof. The goggle frame <NUM> may include soft polymeric materials, such as an elastomeric material, (e.g., for comfort) typically along a portion of the goggle frame which is designed to rest against the user's forehead.

It will be further appreciated that although certain advantages or benefits are discussed with reference to some of the embodiments herein, some embodiments of the present disclosure may not provide all or any of these advantages or benefits.

an inner lens (<NUM>) spaced from and attached to the outer lens by a spacer (<NUM>) to form a dual-lens structure (<NUM>), wherein a periphery of the spacer extends beyond a periphery of the inner lens;
a lens frame (<NUM>) coupled to the dual-lens structure (<NUM>) such that the lens frame (<NUM>) supports the inner lens (<NUM>) and the spacer (<NUM>), wherein the lens frame (<NUM>) is coupled to the periphery of the spacer and extends along a peripheral portion of the inner lens (<NUM>) whereby the inner lens (<NUM>) is captured between the lens frame (<NUM>) and the spacer (<NUM>), and wherein the lens frame includes a number of magnet seats corresponding to a number of the plurality of first magnetic elements;
a plurality of second magnetic elements (<NUM>), each positioned in a respective magnet seat on the lens frame such that the plurality of second magnetic elements is configured to magnetically couple the dual-lens assembly to the goggle frame via magnetic attraction between the first and second pluralities of magnetic elements; and
a second latch component (<NUM>) coupled to the lens frame and configured to mechanically engage the first latch component to removably secure the dual-lens assembly to the goggle frame.
