Description

Technical Field

[0001] This application relates to the field of swimming goggles technology, and in particular to a two-point snap-on swimming goggle. Background Technology

[0002] Traditional swimming goggles often use multiple points of fixation with adhesive. After prolonged use, due to water pressure and frequent movement, the lenses and frames are prone to displacement, loosening, or even separation, affecting the seal and clarity of vision. In addition, the disassembly process is cumbersome and may damage components; the connection between the lenses and frames is not secure and disassembly and assembly are difficult.

[0003] Meanwhile, conventional swimming goggles have thicker rims, causing localized pressure to be concentrated on the nasal cavity and the protruding bones around the eyes. The thick rims result in a strong feeling of pressure and poor comfort when worn, and prolonged wear can cause pain or pressure marks. At the same time, the thick design limits the ability to flexibly adapt to different face shapes, reducing versatility and user satisfaction. Summary of the Invention

[0004] In view of the aforementioned problems, this application is made to provide a two-point snap-on swimming goggle that overcomes or at least partially solves the aforementioned problems.

[0005] This invention discloses a two-point snap-on swimming goggle, including a nose bridge, a strap, two frames, and two lenses;

[0006] The lens has a protrusion on one side and a protruding ring on the other side. The frame has a groove corresponding to the position of the protrusion and a through hole corresponding to the shape of the protruding ring. The protrusion engages with the groove and the protruding ring engages with the through hole.

[0007] The two frames are connected by the nose bridge, and the lens strap is disposed on the raised ring.

[0008] Furthermore, the raised ring has a trapezoidal structure.

[0009] Furthermore, it also includes an eye mask disposed on the frame.

[0010] Furthermore, the eye mask is surrounded by a uniformly distributed rectangular raised dot matrix texture.

[0011] Furthermore, the lens is made of PC injection molding, and the lens thickness is 2-5 mm.

[0012] Furthermore, the lens surface is provided with an anti-fog coating.

[0013] Furthermore, the lens strap is made of silicone, and the inner side of the lens strap is provided with anti-slip texture, the raised height of the anti-slip texture being 0.3 to 0.5 mm.

[0014] Furthermore, the lens strap is provided with adjustment buckles at both ends, which are used to adjust the length of the lens strap.

[0015] This application has the following advantages:

[0016] In the embodiments of this application, addressing the shortcomings of existing swimming goggles—difficulty in assembling and disassembling the frames and lenses, and unstable installation—this application proposes a two-point snap-on swimming goggle, including a nose bridge, a strap, two frames, and two lenses. Each lens has a protrusion on one side and a protruding ring on the other. The frames have grooves corresponding to the protrusions and through holes corresponding to the protruding rings. The protrusions engage with the grooves, and the protruding rings engage with the through holes. The two frames are connected by the nose bridge, and the strap is positioned on the protruding rings. By fixing the lenses and frames with the protrusions and rings, bidirectional precise positioning and double stable fixation are achieved. Furthermore, disassembly only requires a light press on the protruding rings to easily separate the lenses from the frames. This ensures structural stability, simplifies the operation process, and avoids the unreliability and maintenance difficulties of traditional swimming goggles. Attached Figure Description

[0022] To make the objectives, features, and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0023] The inventors, through analysis of existing technologies, discovered that traditional swimming goggles often use multi-point fixation combined with adhesive. After prolonged use, due to water pressure and frequent movement, the lenses and frames are prone to displacement, loosening, or even separation, affecting sealing and visual clarity. Furthermore, disassembly is cumbersome and may damage components; the connection between the lenses and frames is unstable and difficult to install and remove.

[0024] Reference Figure 1-3 The diagram shows a two-point snap-on swimming goggle, including a nose bridge 400, a strap 300, two frames 200 and two lenses 100;

[0025] The lens 100 has a protrusion 101 on one side and a protrusion ring 102 on the other side. The frame 200 has a groove 201 corresponding to the position of the protrusion 101 and a through hole 202 corresponding to the shape of the protrusion ring 102. The protrusion 101 is engaged with the groove 201 and the protrusion ring 102 is engaged with the through hole 202.

[0026] The two eyeglass frames 200 are connected by the nose bridge 400, and the eyeglass strap 300 is disposed on the protruding ring 102.

[0027] It should be noted that the lens 100 and the frame 200 are securely connected by a snap-fit ​​structure. The lens 100 has a protrusion 101 on one side and a protrusion ring 102 on the other side. The corresponding frame 200 has a groove 201 at the position opposite to the protrusion 101 and a through hole 202 of a suitable shape at the position opposite to the protrusion ring 102. During assembly, the protrusion 101 of the lens 100 snaps into the groove 201 of the frame 200, and the protrusion ring 102 of the lens 100 snaps into the through hole 202 of the frame 200. The two frames 200 are connected as a whole by the nose bridge 400, and the lens strap 300 is set on the protrusion ring 102 of the lens 100 to form a complete swimming goggle structure.

[0028] In the embodiments of this application, addressing the shortcomings of existing technologies such as difficulty in assembling and disassembling the frame 200 and lens 100 of swimming goggles, and unstable installation, this application proposes a two-point snap-on swimming goggle, including a nose bridge 400, a strap 300, two frames 200, and two lenses 100; one side of each lens 100 has a protrusion 101, and the other side of each lens 100 has a protruding ring 102. Each frame 200 has a groove 201 corresponding to the protrusion 101, and a through hole 202 corresponding to the shape of the protruding ring 102. The protrusion 101 engages with the groove 201, and the protruding ring 102 engages with the through hole 202. The two frames 200 are connected by the nose bridge 400, and the strap 300 is disposed on the protruding ring 102. The lens and frame are fixed by protrusions and protruding rings, achieving precise bidirectional positioning and double stable fixation. At the same time, the lens and frame can be easily separated by simply pressing the protruding ring during disassembly. This not only ensures structural stability but also simplifies the operation process, avoiding the unreliability and maintenance difficulties of traditional swimming goggles.

[0029] The following will further describe a two-point snap-on swimming goggle in this exemplary embodiment.

[0030] In one embodiment of this application, the protruding ring 102 has a trapezoidal structure.

[0031] It should be noted that the raised ring 102 that mates with the through hole adopts a trapezoidal structure. This trapezoidal design can precisely fit with the corresponding trapezoidal through hole 202 on the frame 200, which is made of the same shape as the raised ring 102. The trapezoidal structure enhances the stability of the connection between the raised ring 102 and the through hole 202, preventing the connection from loosening due to water pressure or movement during swimming. At the same time, it does not affect the ease of disassembly and assembly. The raised ring 102 can be separated from the through hole by pressing lightly. At the same time, the trapezoidal structure of the raised ring 102 also provides installation space for the lens strap 300, ensuring that the lens strap 300 is not easily displaced after being set.

[0032] In one embodiment of this application, an eye mask 500 is also included, which is disposed on the frame 200.

[0033] It should be noted that the goggles 500 can be attached to the two frames 200 by snapping them together. They can fit snugly against the side of the frames 200 facing the eyes, which can not only form a close fit with the skin around the eyes when worn, thus helping to enhance the waterproof seal of the goggles and prevent water from seeping in during swimming, but also buffer the direct contact between the edges of the frames 200 and the eyes, reducing discomfort during wear and improving the user experience of the goggles.

[0034] In one embodiment of this application, the eye mask 500 is surrounded by a uniformly distributed rectangular raised dot matrix texture.

[0035] It should be noted that, to increase the overall thinness, the edges of the eye mask 500 can be made thinner, and a rectangular raised dot matrix texture can be evenly distributed. This reduces direct pressure on the skin by making it thinner; the dot matrix texture forms a support network, distributing the weight of the lens to a larger contact area; and the even distribution of pressure avoids overload on a single point, significantly improving comfort and fit during long-term wear.

[0036] In one embodiment of this application, the lens 100 is formed by PC injection molding, and the thickness of the lens 100 is 2-5 mm.

[0037] It should be noted that the lens 100 is made of PC (polycarbonate) material and manufactured through injection molding. This process precisely shapes the overall shape of the lens 100, ensuring that the dimensions of each component meet the required accuracy. Simultaneously, PC material itself possesses excellent light transmittance, guaranteeing clear vision while swimming; it also boasts strong impact resistance and weather resistance, able to withstand potential collisions, water flow impacts, and pool environment corrosion during swimming, extending the lens's lifespan. Furthermore, the thickness of the lens 100 is controlled between 2 and 5 mm, avoiding the structural fragility and easy breakage issues caused by excessive thinness, while also preventing excessive thickness from increasing the overall weight of the goggles and affecting the lightness and clarity of vision. It also provides sufficient structural support for the protrusions and protrusion rings, ensuring stability when engaging with the groove 201 and through-hole 202, balancing practicality and wearing comfort.

[0038] In one embodiment of this application, the surface of the lens 100 is provided with an anti-fog coating.

[0039] It's worth noting that fogging of the lens is a common problem in diving applications. When the user's exhaled breath comes into contact with the cool surface of the lens, the water vapor in the breath condenses into tiny water droplets, which adhere to the lens and form fog, causing blurred vision. An anti-fog coating is used to protect the lens and reduce fogging.

[0040] In one specific implementation, a silica nano-coating is used as the anti-fog coating. A silica nanofilm is formed on the surface of a PC lens using a sol-gel method. The surface of this nanofilm contains numerous hydroxyl groups, exhibiting strong hydrophilicity. The nanoscale porous structure can adsorb water vapor and diffuse it rapidly, achieving the anti-fog effect. Simultaneously, the silica coating has high hardness and good wear resistance, and its coefficient of thermal expansion is similar to that of the PC lens, making it less prone to peeling off under temperature changes and able to withstand long-term underwater environmental conditions.

[0041] In one embodiment of this application, the lens strap 300 is made of silicone, and the inner side of the lens strap 300 is provided with anti-slip texture, the protrusion height of the anti-slip texture being 0.3 to 0.5 mm.

[0042] It should be noted that the goggle strap 300 is made of silicone. Silicone is soft and skin-friendly, conforming to the contours of the head during wear and reducing the feeling of tightness during prolonged wear. Its excellent water and corrosion resistance allows it to withstand immersion in pool water or seawater, preventing material aging and deformation and extending the lifespan of the goggle strap. Furthermore, the inside of the goggle strap 300 features anti-slip textures with a raised height of 0.3–0.5 mm. These textures effectively enhance the anti-slip effect through friction with the scalp, preventing the strap from shifting due to head rotation and water pressure during swimming, ensuring a stable fit. However, the textures also prevent excessive pressure or scratches on the scalp, thus balancing anti-slip functionality with wearing comfort.

[0043] In one embodiment of this application, the lens strap 300 is provided with adjustment buckles at both ends, and the adjustment buckles are used to adjust the length of the lens strap 300.

[0044] It should be noted that the adjustment buckles allow users to precisely adjust the length of the mask strap by 300mm according to their own head characteristics, making the diving mask fit the individual's head better, reducing swaying or pressure caused by size mismatch, and improving wearing comfort and stability. The adjustment buckles at both ends of the mask strap are reasonably designed, allowing users to quickly operate them with one or both hands during the wearing process without the need for tools, making them suitable for quick operation underwater or in emergency situations.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the embodiments of the present application.
