Description

Technical Field

[0001] This invention belongs to the field of eyewear technology, specifically relating to a forehead-worn eyeglass. Background Technology

[0002] Nearsightedness is commonplace in modern society, and the number of people wearing glasses is growing rapidly. Prolonged desk work or study requires frequent adjustments to glasses, especially for those with high myopia, thick lenses, or oily skin. Over time, wearing glasses can compress the nose and ears, causing discomfort and even visible pressure marks. In summer, oily and sweaty skin can also cause glasses to slip, requiring frequent adjustments and causing inconvenience in daily life and work. Once the frames and lenses are chosen, they cannot be changed and must be worn for a long time. If the glasses are accidentally dropped or bumped, the frame may deform, altering the optimal lens-to-eye distance and tilt angle. This misalignment can increase eye strain and damage the eyes, potentially worsening myopia, especially causing irreversible damage to adolescents during their growth period.

[0003] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

Detailed Implementation

[0025] To make the technical means, creative features, objectives and effects of the present invention easy to understand, the forehead-mounted glasses of the present invention will be specifically described below in conjunction with embodiments and accompanying drawings.

[0026] <Example 1>

[0027] This embodiment provides a detailed description of the structure and usage of forehead-worn glasses.

[0028] Figure 1 This is a schematic diagram of the forehead-mounted glasses in Embodiment 1 of the present invention; Figure 2 This is a structural schematic diagram of the forehead-mounted glasses in Embodiment 1 of the present invention from another angle. Figure 2 The forehead band is omitted.

[0029] like Figure 1 , 2 As shown, the forehead-worn glasses 100 includes a forehead band 10, a frame 20, lenses 30, nose pads 40, a frame cable 50, a forehead band fixing clip 60, an L-shaped forehead support cantilever 70, and a nose pad cable 80.

[0030] The forehead band 10 is worn on the user's head, with a thickness of 1mm-5mm and a width of 10mm-35mm. It is a flexible strap or restraint band, made of skin-friendly materials such as silicone or elastic blended fiber fabric. Anti-slip silicone can be added to the inner side (the side that contacts the forehead). The forehead band 10 can be secured by its own elasticity or by Velcro, adjustable buttons, or strap connectors. Users can choose different materials, colors, and widths of forehead bands according to their preferences. For some relatively soft materials or narrower forehead bands, to increase their rigidity, a rigid plate can be embedded in the forehead area where it mates with the forehead band fixing clip, or the material thickness can be increased to form a reinforcing protrusion, ensuring that it does not deform after assembly with the forehead band fixing clip.

[0031] The frame 20 is a long strip with a rectangular cross-section. The outer middle portion has a recessed groove that matches the width and thickness of the frame cable 50. The frame cable 50 is attached upwards along this groove and fixedly connected to the forehead band clip 60. The frame 20 can be made of lightweight materials such as pure titanium. Two lenses 30 are connected by a nose pad 40 and are non-removably fixed to the frame 20, or they can be detachably fixed to the frame using a snap-fit ​​method. When using the snap-fit ​​method, the frame 20 has a groove that matches the lens 30; the lens 30 can be inserted and snapped into place. The lenses 30 are selected as needed and should preferably be made of lightweight materials.

[0032] The nose pad 40 matches the bridge of the nose, wrapping around the nose on three sides. It comes in several sizes (large, medium, and small) to match the shape and size of the wearer's nose, achieving the best wrapping effect. It works in conjunction with the forehead strap clip and forehead support cantilever for optimal positioning and wearing comfort. In this embodiment, since the weight of the glasses is almost entirely supported by the forehead support cantilever, the nose pad primarily serves a positioning and fixing function. Unlike conventional glasses where most of the weight rests on the nose, causing discomfort and requiring specific design and material features such as pressure relief and anti-slip properties, the nose pad material in this embodiment is not limited to conventional materials. Fabrics, fibers, and other materials can be used, and more diverse forms and appearances such as openwork and wire frames can also be employed.

[0033] The frame cable 50, forehead strap clip 60, L-shaped forehead support cantilever 70, and nose bridge cable 80 are integrally molded to form a fixing support unit, used to fix the lenses at a predetermined position away from the eyes. The fixing support unit can be customized after scanning the user's facial data, using 3D printing or integral injection molding, and the materials selected are PLA and / or TPU, titanium, etc.

[0034] The fixing support can also be integrally molded from skin-friendly materials such as synthetic fibers, TPE, TPR, or silicone. Because these materials are relatively flexible, the forehead band fixing clip 60 and forehead support cantilever 70 can be embedded in or have a secondary injection molded elastic rigid material such as a metal sheet (e.g., titanium alloy) or a plastic sheet (e.g., PP, PET, PBT). Figure 3 As shown, the two parts of the insert are integrally molded to form the insert piece 74. When using the insert, the insert piece 74 can be detached or non-detachable. If a secondary injection molding process is used, the insert piece 74 is non-detachable.

[0035] The forehead band fixing clip 60, formed by an embedded metal sheet (such as titanium alloy) or elastic plastic sheet (such as PP, PET, PBT), engages with the forehead band 10 and secures it. The forehead support cantilever 70, with its embedded or double-injected L-shaped lightweight alloy sheet (such as titanium alloy) or plastic sheet (such as PP, PET, PBT), provides strong support for the upper edge of the frame. The frame cable 50 and nose pad cable 80 are relatively flexible and work in conjunction with the forehead support cantilever 70 to secure the glasses to their optimal position and angle.

[0036] The forehead band fixing clip 60 has a flat contact portion with the forehead and an arc-shaped curvature away from the forehead. Because the glasses themselves are relatively light—for example, a traditional pure titanium frame with temples weighs only 5-12g—the glasses in this embodiment only consist of lenses and a frame, and the absence of temples makes them even lighter. Therefore, stability and preventing slippage can be ensured solely by the forehead band fixing.

[0037] The aforementioned L-shaped forehead support cantilever includes a horizontal cantilever 71, a vertical arm 72 for contacting the forehead, and a limiting protrusion 73 located at the inner end of the horizontal cantilever 71 extending outward. Figure 1 , 2(Not shown in the text). Among them, such as Figure 3 As shown, the end of the horizontal cantilever 71 curves vertically upwards, forming a 90-degree angle with the vertical arm 72. The horizontal cantilever 71 is 5mm-30mm long, and the vertical arm 72 is 20mm-80mm long. The frame 20 is positioned between the curved portion of the horizontal cantilever 71 and the limiting protrusion 73.

[0038] The frame cable 50, the forehead strap clip 60, and the L-shaped forehead support cantilever 70 are connected end to end to form an upper triangle. The two ends of the nose pad cable 80 are connected to the two ends of the horizontal cantilever 71, passing through the middle of the nose pad 40 to form a lower triangle with the horizontal cantilever 71.

[0039] Since getting glasses still requires a visit to a professional optician, and the correct wearing method directly affects the effectiveness of the glasses, the forehead-mounted glasses in this embodiment also require professional adjustment based on each person's unique facial features, especially the distance between the forehead, eyes, and nose. The core adjustment is the forehead support arm. The horizontal arm 71 can be preset in several sizes, such as 5mm, 8mm, 14mm, 18mm, 22mm, 26mm, and 30mm, for customers to choose from. Generally, 8-22mm is sufficient, but for some extra-large frames and lenses, if the wearer has a flat forehead, 26mm or even 30mm may be necessary. Alternatively, for faces with sunken eyes, such as those with high brow bones common in Caucasians, 5mm might be chosen. Upon initial purchase and wearing, a professional will select the optimal size, such as the horizontal arm 71 and forehead band style, based on the consumer's individual circumstances. Adjustments must adhere to the two most important data points for wearing glasses: a distance of 12mm between the eyes and the lens; and an optimal forward tilt angle of 8-10 degrees.

[0040] The role and effect of the embodiments

[0041] The forehead-mounted glasses provided in this embodiment, due to the back-to-back upper and lower triangular structure of the fixing support, very stably fix the lenses at a predetermined position away from the eyes. Furthermore, because it adopts a forehead-band wearing style, the common temples of glasses are omitted. Therefore, through the cooperation of the forehead band and the fixing support, the glasses are firmly fixed at a fixed optimal angle and position, effectively relieving pressure on the nose and ears. They are not affected by skin oil and sweat, do not slip down, and can maintain the optimal wearing angle and posture of glasses in relatively static or slow-moving states such as working at a desk and studying, protecting the eyes and thus ensuring the best work and study efficiency.

[0042] The headband clip, the horizontal cantilever, the frame, and the lenses are all detachable. If, in summer, skin becomes oily or sweaty and the contact parts of the headband get dirty, they can be removed for washing and drying before use without deformation. Furthermore, the glasses in this embodiment are made primarily of soft materials and are detachable, making them convenient for storage and portability.

[0043] <Example 2>

[0044] like Figure 4 As shown, the forehead-worn glasses 200 of this embodiment are the same as those in Embodiment 1, except that the structure of the frame cable and nose pad cable is different from that of the frame cable 50 and nose pad cable. They will not be described again, and the same structure will be given the same number.

[0045] The frame cable includes an upper cable 521 and a lower cable 522 that are detachably fixed together. The nose bridge cable extends upwards after being tightly fitted to the outer end of the horizontal cantilever 71; this extension is the nose bridge cable extension section 801, which partially overlaps with the upper cable 521 for detachable fixing. One end of the upper cable 521 is fixedly connected to the upwardly curved portion of the horizontal cantilever 71, while the other end is free. One end of the lower cable 522 is fixedly connected to the forehead strap clip, while the other end is free. All fixed connections can be integrally formed.

[0046] The nose pad cable and frame cable are made of skin-friendly materials such as synthetic fibers, TPE, TPR, or silicone. Velcro is then attached to the nose pad cable extension 801, the upper cable 521, and the lower cable 522, with each pair of the three cables secured together in an adjustable manner using the Velcro. During wear, the length of the frame cable and nose pad cable can be adjusted using the Velcro, thereby adjusting other components such as the forehead strap clip, forehead support arm, frame cable, and nose pad cable to better fit the wearer, achieving a personalized fit. This method is more economical than 3D printing / integral injection molding. Generally, once these parts are adjusted, they will remain stable unless excessively stretched, allowing the wearer to maintain their position for an extended period. If accidental stretching or impact causes discomfort, the Velcro / adjustable snaps can be opened for readjustment.

[0047] Since the upper cable 521, lower cable 522, and nose bridge cable can be separated in pairs, the entire unit can be divided into three parts: the fixing support, the forehead strap, and the glasses. Each of these three parts can be washed and dried independently according to their respective properties before being reassembled. Therefore, if the forehead strap or other contact parts become dirty due to oily skin or sweat in the summer, or if the lenses become dirty, they can be removed for washing and drying before use without deformation.

[0048] <Example 3>

[0049] like Figure 5 As shown, the forehead-worn glasses 300 of this embodiment is the same as that in Embodiment 1, except that the structure of the frame cable and nose pad cable is different. It will not be described again, and the same structure will be given the same number.

[0050] The frame cable includes an upper cable 531 and a lower cable 532 that are detachably fixed together. The nose bridge cable extends upwards after being tightly fitted to the outer end of the horizontal cantilever 71; this extension is the nose bridge cable extension section 802, which partially overlaps with the upper cable 531 for detachable fixing. One end of the upper cable 531 is fixedly connected to the upwardly curved portion of the horizontal cantilever 71, while the other end is free. One end of the lower cable 532 is fixedly connected to the forehead strap clip, while the other end is free. All fixed connections can be integrally formed.

[0051] The nose bridge cable, upper cable 531, and lower cable 532 can be made of skin-friendly materials such as synthetic fibers, TPE, TPR, or silicone. Multiple buckles are provided on the upper cable 531 and the nose bridge cable extension 802, while multiple protruding locking posts 533 are provided on the lower cable 532. The locking posts 533 pass through the buckles to form a locking structure, thereby adjustingly fixing the nose bridge cable, upper cable 531, and lower cable 532 together.

[0052] The technical effect of the locking structure is the same as that of the Velcro in Example 2, and will not be repeated here.

[0053] <Example 4>

[0054] like Figure 6 As shown, in this embodiment, the forehead-mounted glasses 400, the forehead strap fixing clip 60a and the forehead support cantilever 70a are made of hard and elastic materials, such as alloy, PP, PET, which have sufficient elasticity and hardness. Therefore, there is no need to embed / or re-inject and mold lightweight alloy or plastic sheets. The rest of the structure is the same as in embodiment 2, and will not be described again. The same structure will be given the same number.

[0055] <Example 5>

[0056] like Figure 6 As shown, in this embodiment, the forehead-worn glasses 500, the forehead band fixing clip 60b and the forehead support cantilever 70b are made of hard and elastic materials, such as shape memory alloy, PP, and PET. The elasticity and hardness are sufficient, so there is no need to embed or re-inject and mold lightweight alloy sheets or plastic sheets. The rest of the structure is the same as in embodiment 3, and will not be described again. The same structure will be given the same number.

[0057] The above embodiments are preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention.
