[0039] The single block frame (2) comprises two rear recesses (2A), each parallel and symmetrically arranged along the entire length of the inner side ends of each one of the openings in the frame (2); and two lateral brackets (2B) each perpendicular and symmetrically arranged in a top rear end of the frame (2) and having a lateral cutout (2C) parallel and symmetrically arranged in the inner side of the lateral brackets (2B), a recess (2D) parallel and symmetrically centered on the inner surface of the lateral bracket (2B) and of the lateral cutout (2C), a recess (2E) perpendicular and symmetrically arranged in the front inner part of the lateral cutout (2C), and two openings (2F) symmetrically and vertically aligned between the top and bottom surfaces of the lateral brackets (2B).

[0040] Each one of the eye cups (3) is constituted as a single block by a hollow front base (3A), symmetrically arranged along the entire front length of the eye cup (3) to fit the rear recess (2A) of the frame (2) and having a tongue type inner profile (3B) symmetrically arranged along the entire inner length of the front base (3A) and a front recess (3C) symmetrically arranged around the entire length of the front ends of the front base (3A); and a rear bracket (3D) that is pliable, hollow and asymmetrical, perpendicular and symmetrically arranged around the entire length of the rear ends of the front base (3A) and having a rear rim (3E) perpendicular and symmetrically arranged around the entire rear length of the rear bracket (3D), and beehive pattern openings (3F) (non-hollow structure) parallel and symmetrically arranged along the entire outer length of the inner side part of the rear bracket (3D).

[0041] Each one of the two lenses (4) is constituted in a single block by a groove type front cutout (4A) perpendicular and symmetrically arranged around the entire length of the outer ends of the lens (4) and fitted in the tongue type inner profile (3B); and a rear rim (4B) perpendicular and symmetrically arranged around the entire length of the rear ends of the lens (2) and pressed into the inner part of the pad (3).

[0042] Each one of the two curved straps (5) is constituted in a single block, comprising a thick front body (5A) symmetrically arranged at the front end of the strap (5) in the lateral bracket (2B); and a narrow rear body (5B) symmetrically arranged along the entire length of the strap (5) in the back of the front body (5A) and having a concave curve (5C) symmetrically arranged along the entire bottom length of the intermediate area between the front (5A) and rear (5B) bodies.

[0043] The front body (5A) is provided with a front tip (5D) perpendicular and symmetrically centered in the front end of the front body (5A) to be fitted into the lateral cutout (2C), a front projection (5E) perpendicular and symmetrically centered in the front end of the front tip (5D) to be fitted into the recess (2E), an outer projection (5F) parallel and symmetrically centered in the outer surface of the front tip (5D) to be fitted into the recess (2D), a front groove (5G) vertically and symmetrically transversal and centered in the front tip (5D) to be aligned with the two openings (2F), a slight inner convex curve (5H) symmetrically centered in the inner surface of the front body (5A) to allow the strap (5) to bend, a sharp inner concave curve (51) symmetrically arranged in the rear end of the slight inner curve (5H) that allows the strap (5) to bend, an inner recess (5J) parallel and symmetrically centered in the rear part of the inner surface of the front body (5A), a slight bottom tilt (5K) symmetrically arranged along the entire bottom length of the front body (5); and a rear narrowing (5L) parallel and symmetrically arranged along the inner surface of the rear portion of the rear body (5A) and stemming from the sharp inner curve (5I).

[0044] Each one of the two pins (6) is constituted in a single block that traverse the two openings (2F), the lateral cutout (2C) and the front groove (5G).

[0045] The strap adjuster (7) comprises two anterolateral openings (7A) each symmetrically and internally interconnected between the side ends of the front and side surfaces adjacent to the strap adjuster (7) that traverse the rear end of the rear body (5B); and two snap locks (7B) parallel and symmetrically spaced in the rear outer surface of the strap adjuster (7) and transversally seeping into each anterolateral opening (7A) that fits the rear end of the rear body (5B).

[0046] The sunglasses for use in water activities are provided with a simple and direct operation based on the proper placement and handling at the eye area and around users' heads. Care must be taken when securing them around the head, such as the ones described below.

[0047] The two eye cups (3) for water environments must be properly positioned/placed and pressed around the eye area, so as to create seamless watertightness in the region, just as the frame (2) must be positioned along the entire front length of the eye area and placed on the nose, and the two lenses (4) for viewing/protection/correction for solar environments placed before the eye area.

[0048] The two straps (5) should be slightly flexed along the two sides of the user's head starting at the frame (2) where they are attached by two pins (6) to hold the straps (5) to the frame (2) up to their two rear ends where they are fitted and aligned by the strap adjuster (7).

[0049] The fastening of the two straps (5) to the frame (2) is based on a tongue and groove fit between the tongue type front ends of the straps (5) and the groove type rear side ends of the frame (2). Likewise, the fastening of the two straps (5) to the frame (2) is based on the vertical trespassing of the pin (6) into the tongue and groove joint area of the strap (5) and the frame (2).

[0050] More specifically, said fastening is carried out by the front body (5A) directly fastened to the lateral bracket (2B), that is, the front tip (5D) jointly fits the lateral cutout (2C), the front projection (5E) fits the recess (2E), the outer projection (5F) fits the recess (2D) and the front groove (5G) is trespassed by the pin (6).

[0051] This type of fastening between the two straps (5) and the frame (2) enables, in a simple, practical and safe way, and directly by the users, the combination of different types of frames (2) and straps (5) making use of varied types of designs and colors. Thus, the overall design can be changed as desired by the user at any time.

[0052] The innovative design of the two straps (5) is based on a differentiated thickness and geometrical shape along their entire length, starting wider and thicker on their front end, i.e., the area adjacent to the frame (2), and then tapers—becoming thinner and narrower along the entire rear length, so that the thicker front portion is stable or intact and the tapered rear portion dents to fit into the slot, thus ensuring a flawless visual design of the sunglasses for use in water activities (1).

[0053] Thus, the design of the two straps (5) is similar to that of traditional/contemporary sunglasses, as well as the comfort and safe fit according to each user's wishes.

[0054] More specifically, the assembly formed in the straps (5) by their slight inner curve (5H), sharp inner curve (5I), inner recess (5J), slight bottom tilt (5K) and rear narrowing (5L), as well as by the thick front body (5A) and narrow rear body (5B) with a concave curve (5C) along the entire bottom length of the intermediate area between the front (5A) and rear (5B) bodies, provides high ergonomics and flexibility of the two straps (5) around the head, and also perfect and symmetrical pressure and watertightness of the eye cups (3) around the eye area.

[0055] The two eye cups (3) are provided parallelly along the length of the outer part of their inner side surfaces, the surfaces adjacent to the users' nose area, more specifically parallel and symmetrically along the entire outer length of the inner side portion of the rear bracket (3D), a set of beehive pattern openings (3F) that have, together with the material of the two eye cups (3), the main function of creating some degree of support by means of lower flexibility or wear and tear in its structure while being worn around the eye area.

[0056] Thus, more comfort and support is achieved when wearing the eye cups (3) by means of a greater support, mainly when adjusting the tightness of the two straps (5) for watertightness without, however, allowing any loss of watertightness and keeping the same design of contemporary sunglasses.

[0057] The two viewing/protection lenses (4) for solar environments (bright light) are directly attached and fitted by their outer ends around the inner ends of the two eye cups (3) for water environments by means of a tongue and groove fit, so as to allow seamless watertightness between the elements when in water environments, as well as the same design of the sunglasses for use in water activities.

[0058] This type of fastening of the two lenses (4) for eyesight/protection for solar environments (bright light) enables the application, in a simple, practical and safe way, and directly by the users, of different types of eyesight/protection lenses such as different colors, protections and corrections. Thus, the type of correction/protection lenses (4) can be changed, as well as the overall design as desired by the user at any time.

[0059] More specifically, this type of fastening of the lens (4) to the pad (3) is carried out by the groove type front profile (4A) that is fitted into the tongue type inner profile (3B), as well as by the rear rim (4B) that is pressure locked into the inner portion of the pad (3).

[0060] It should be noted that the fastening of the straps (5) in the strap adjuster (7) is carried out by trespassing the rear ends of the rear bodies (5B) of the straps (5), more specifically by trespassing the rear ends of the rear bodies (5B) through the anterolateral openings (7A) of the front and side surfaces adjacent to the strap adjuster (7), just like the fastening is carried out by engaging the two snap locks (7B) that transversally seep into the anterolateral openings (7A) and press the rear ends of the rear bodies (5B).

[0061] As the sunglasses for use in water activities have fully integrated components, it can be assembled and disassembled quickly, nothing comes loose or breaks off, and a high performance and efficiency is achieved, combined with high durability and complete safety during use. Once fully integrated, and adjusted to the wearers' eyes and heads, the components are completely locked and united, thus preventing them from loosening when in use, making the assembly fully available for the helping the user's eyesight and solar and/or water protection. The sunglasses for use in water activities (1) can be thus used without concerns of any nature, mainly regarding the safety and durability of their components, as well as the safety of their users, primarily the eye area.

[0062] The sunglasses for use in water activities feature as specific advantages: seamless watertightness of the eye area in water environments; perfect protection of the eye area in situations where bright light/glare is an issue and sun/ultraviolet rays; possibility of eyesight correction due to some kind of visual impairment; possibility of using the most diverse types of combinations/designs in its frame such as social, recreational, sports and professional activities; high versatility while adjusting the glasses around the eye area and the head; and possibility of employing several different types of lenses (4) for eyesight/protection/correction.

[0063] In view of the foregoing, the sunglasses for use in water activities will be well received by eye wear users who enjoy swimming and diving in social, recreational or sports activities, since the sunglasses for use in water activities has many advantages, such as: great safety, reliability and flexibility in its application; great efficiency and performance in its application due to its general conception; great comfort, convenience and safety for the users; great overall strength and durability, combined with low or no wear of the assembly as a whole; fully accessible costs which provides an optimum cost-benefit ratio; practical and safe use by any users; high range; perfect and direct adaptation to different types of social, recreational and/or sports applications; great mobility and flexibility of the assembly; high ergonomics; and the certainty of having sunglasses for use in water activities (1) that fully meets the current rules and regulations to its application.

[0064] All such attributes classify the sunglasses for use in water activities as a fully versatile, efficient, practical and safe way to be applied in the most diverse types of applications for clear eyesight and solar and/or water protection and several types of users in the most varied types of environments, regardless of the general characteristics these may have. However, it is understood that the present invention is not limited to the specific embodiments described herein, but its objective is to encompass variations and modifications within the scope of protection thereof as defined in the attached claims.
