Spectacles with multidirectional ventilation

Abstract

Multi-directional vents or multiple multi-directional vents can be integrated into eyewear to allow for venting of the eyewear. The vents can be tilted and angled in different directions to increase airflow and multi-directional venting. Grooves can be formed on the lens and / or frame portion of the eyewear such that when the lens is joined to the frame portion, vents are formed. The vents can also include ribs extending from the frame portion to allow air to be directed in a controlled and precise manner.

Description

Technical Field

[0001] The following generally refers to eyeglass frames, and more specifically to eyeglasses that provide multi-directional ventilation. Background Technology

[0002] Eyeglasses, such as corrective lenses, typically include a frame that supports one or more lenses. The frame usually includes a bridge or nasal section that engages with the user's nose to support the glasses on the user's head. Eyeglasses also typically include a pair of arms attached to (or integrated with) the frame to further support the glasses, for example, by resting the arms on the user's ears or engaging their head in the temple area. Some eyeglasses may include additional support elements, such as strips or straps (e.g., in sports glasses), to seal against the wearer's face, preventing foreign objects or wind from entering that area. Safety glasses may also be fitted onto the user's main glasses to protect both the glasses and the user. However, these arrangements can affect the wearer's vision because the lenses may fog up due to sweat and warmth emanating from the wearer's face or that area, caused by insufficient airflow.

[0003] To address this issue, eyeglass manufacturers have incorporated vents into the frame structure to allow moisture and heat to escape from the space between the glasses and the wearer's face. However, these vents are generally ineffective at reducing lens fogging.

[0004] The following objective is to address at least one of the aforementioned drawbacks. Summary of the Invention

[0005] In one aspect, an eyeglass frame is provided, comprising a lens portion and a frame portion connected to the lens portion via an attachment mechanism. A lens recess may be disposed on the lens portion; and a frame recess may be disposed on the frame portion. When the lens portion is connected to the frame portion, the lens recess may be aligned with the frame recess to form a vent. The vent allows air to enter the lens. The lens recess may be angled in multiple directions, such that air is guided in multiple directions through the angled recess.

[0006] On the other hand, a method for manufacturing eyeglasses with multidirectional ventilation openings is provided. The method includes the steps of: forming a lens recess in a lens portion; forming a frame recess in a frame portion; and connecting the frame portion to the lens portion such that the lens recess and the frame recess are aligned to form ventilation openings. Furthermore, the lens recess is angled in multiple directions, allowing air to enter the eyeglasses through the ventilation openings, thereby guiding the air in multiple directions.

[0035] It should also be noted that throughout the following description and claims, the terms “front” / “forward” and “back” / “rear” (“behind”) refer to the direction from the user’s perspective; that is, the direction further away from the user’s face is referred to as “front” or “forward”, while the direction closer to the user’s face is referred to as “back” or “behind”.

[0036] Figure 1A rear view of a prior art eyeglass assembly with conventional vents 102a, 102b integrated into a frame 101 is provided. Vents 102 are located between the frame 101 and the lens 104. Vents 102 allow moisture and heat to escape from the space between the glasses and the wearer's face; however, these vents 102 tend to restrict downward airflow and may not reach the area spanning the space between the glasses and the user's face. As can be seen from the arrows 105a, 105b indicating airflow across the lens, the airflow is unidirectional. It has been found that such unidirectional airflow may not be effective in reducing lens fogging and may only reduce fogging on one side of the lens. To overcome this drawback and improve airflow circulation between the glasses and the user's face, multidirectional ventilation arrangements, such as... Figure 2 As shown.

[0037] Figure 2 A front view of spectacle lenses 202a and 202b is provided. A groove 201 may be provided on lens 202 to allow airflow through it. The groove 201 located on the lens 202 of the spectacle is referred to herein as a lens groove 201. It is understood that any number of lens grooves 201 are possible, including a single lens groove 201; however, multiple lens grooves 201 are preferred. The lens groove 201 may be located at the edge of lens 202, preferably at the location where the frame portion connects to lens 202. The lens groove 201 may be shaped such that the groove can be tilted towards the wearer's face (when the wearer wears the spectacle), allowing air to easily travel into the space between the spectacle and the wearer. Furthermore, the lens groove 201 may be angled in different directions to increase airflow throughout the spectacle and allow for multidirectional ventilation. For example, lens groove 201a is angled downwards towards the bottom of the lens, lens groove 201b is angled towards the center of the lens, and lens groove 201c is angled towards the nose 203. This allows air to enter and ventilate the lens more evenly through the bottom, middle, and interior of the lens compared to using unidirectional flow.

[0038] Figure 3 yes Figure 2The diagram shows a front view of the eyeglass assembly. The frame portion 302 can be attached to the lens portion 202 using an attachment mechanism 204. The frame portion 302 may include another set of recesses 301 complementary to the recesses 201 of the lens portion 202. The recesses located on the frame of the eyeglasses are referred to herein as frame recesses 301. The number of frame recesses 301 is preferably equal to the number of lens recesses 201. Furthermore, the frame recesses 301 are preferably shaped to match the lens recesses 201 such that the width of the lens recesses 201 is approximately equal to the width of the frame recesses 201. The frame recesses 301 may be tilted toward the wearer's face (when the wearer wears the eyeglasses) to allow air to easily travel into the space between the eyeglasses and the wearer. The frame recesses 301 may be formed on the frame portion 302 such that when the lens recesses 201 are aligned with the frame recesses 301, a multi-directional vent 310 is formed.

[0039] The provided eyeglasses include a lens portion 202 and a frame portion 302 attached to the lens portion 202 via an attachment mechanism 204. A lens recess 201 is provided on the lens portion 202; and a frame recess 301 is located on the frame portion 302. When the lens portion 202 is attached to the frame portion 302, the lens recess 201 can be aligned with the frame recess 301 to form a vent 310. The vent 310 allows air to enter the area behind the lens. The lens recess 201 can be angled in multiple directions, such that air is guided in multiple directions through the angled recess.

[0040] Figure 4 A rear view of an eyeglass assembly with a multi-directional vent 310 integrated into a frame 302 is provided. Multi-directional ventilation is provided by lens recesses 201 that can be angled in different directions. This increases airflow throughout the eyeglasses in many directions and allows for multi-directional ventilation. In this embodiment, a first lens recess (not shown) angles airflow 401a downwards toward the bottom of the lens, a second lens recess (not shown) angles airflow 401b toward the center of the lens, and a third lens recess (not shown) angles airflow 401c toward the nose 203. This multi-directional airflow allows air to enter and exit equally at the bottom, center, and interior of the lens.

[0041] Figure 5a Provided Figure 3 The image shows a cross-sectional view of the eyeglass assembly taken along line AA. Figure 5b Provided Figure 5a The enlarged view of the eyeglass assembly shown illustrates the airflow through the frame. It can be understood that the multi-directional vent 310 preferably does not allow air to enter the area behind the lens in a straight path. The airflow 401 is guided through recesses and may not follow a straight path. For example, in Figure 5bIn the illustrated embodiment, vent 310 allows air to enter the recess via a horizontal path, then the air is guided vertically upward toward the frame recess, and finally vertically downward into the area behind the lens (airflow path indicated by arrow 501). This allows air to be guided in a specific manner. Furthermore, the recess can be angled, such that airflow is directed to areas behind the lens that require more ventilation. For example, the recess can be angled acutely toward the nose to ventilate the area near the nose more than other areas. Therefore, the angle of the provided recess can be changed and the airflow guided as needed. It can be understood that by using a greater number of recesses, the ability to redirect air in multiple different directions increases.

[0042] The lens recess 201 and the frame recess 301 together form a generally horizontal channel section and a generally vertical channel section that are in fluid communication with each other. Therefore, in combination, an "indirect" or L-shaped ventilation channel is formed extending through the frame structure. Thus, the "indirect" or L-shaped ventilation channel has an opening on the front side of the frame and an opening on the rear side of the frame. Therefore, the "indirect" or L-shaped ventilation channel allows for effective moisture ventilation and air circulation, while preventing foreign particles passing through the ventilation channel from entering the user's eyes and impacting the user's face.

[0043] Figure 6 A top view of an eyeglass assembly with vents 310 is provided. In this embodiment, it can be understood that air enters each of the vents 310 from different directions. The vents 310 are angled, which allows airflow to fully enter the area behind the lens and ventilate the eyeglasses in a controlled, directional manner.

[0044] Figure 7 This is a partial front view of eyeglasses with a multi-directional vent 310. The vents may be located on one half of the eyeglasses, but preferably, the vents 310 are located on both halves. The frame recess 301 may be slotted or cut deeper than the lens recess 201. This allows the frame 302 to be manufactured separately from the lens 202 and adapted to any lens. This can be useful, for example, when an existing pair of lenses 202 contains a prescription and an additional ventilation system is needed. In this embodiment, the recess is formed only in the frame, and the frame is adapted to an existing lens that does not have a lens recess. In separate embodiments, the recess may be formed only in the lens and adapted to an existing frame. In these embodiments, the multi-directional vent 310 is formed solely by the frame recess or the lens recess.

[0045] Figure 8An alternative embodiment of an eyeglass assembly with multi-directional ventilation is shown. In this embodiment, the frame recess 301 has ribs 312 integrated into the frame. Ribs 312 allow for further control and corresponding guidance of air. Therefore, air can have more movement, and more efficient ventilation of the eyeglasses is permitted. Ribs 312 can guide and push air towards the center of the lens, thereby allowing for further multi-directional ventilation.

[0046] Figure 9 yes Figure 8 The image shows a close-up of the ribs in the eyeglass assembly. It can be understood that the ribs 312 can be overmolded into the frame 302. Figure 10 This is a partial bottom view of the eyeglass frame 302, showing the rib 312 attached to the frame. (As shown from...) Figure 9 As can be seen, rib 312 is located on the frame, behind the frame recess 301. Air can enter the frame recess 301 and is guided in a first direction due to the angled recess. Rib 312 can then guide the air in a second direction, or further guide the air in the first direction. This allows the air to travel in a controlled manner.

[0047] The construction of rib 312 can be accomplished using any suitable overmolding process. Overmolding, sometimes called secondary injection molding, is a process that combines two or more different materials to produce a single component. Typically, during the manufacturing process, a first material (or substrate) is partially or completely covered by the overmolding material. In this case, frame 302 will serve as the substrate, which will be overmolded using the material used to form rib 312 thereon. This material is typically a softer plastic, rubber, or elastomer (such as PTE) or other suitable material. It is understood that the flexible material will typically be overmolded to frame 302 before the component is attached to lens 202.

[0048] Rib 312 can be any suitable shape. In this embodiment, rib 312 is shown as a rectangular shape. It is understood that rib 312 can also be oval or elliptical.

[0049] Figure 11This is a front view of an eyeglass assembly with an alternative rib shape 314. In this embodiment, the rib 314 has an alternative shape integrated into the multi-directional vent 310. The rib 314 is located within the eyeglass frame 302 such that when the lens 202 is assembled to the frame, the rib 314 is located within the multi-directional vent 310. No rib 314 is located on the lens itself. The rib 314 helps to push air into the interior of the eyeglass assembly. In this embodiment, the air will travel into the multi-directional vent 310 and directly impact the rear wall 318 where the rib 314 is located. Thus, the rib 314 will guide the air into the eyeglasses in a controlled manner. It is important to note that in this embodiment, the rib 314 located on the rear wall 318 of the vent 310 guides the air inward. The rib 314 shown in this embodiment can be overmolded into the eyeglass frame using any suitable overmolding process.

[0050] Figure 12 A front view of the lens of the eyeglass assembly is shown, illustrating the ventilation location. A ventilation area 316 is located on the lens 202 of the eyeglasses and defines the ventilation location. Area 316 may be recessed into a lens recess 201, such as... Figure 2 As shown. Figure 13 and Figure 14 A front view of an eyeglass assembly with an overmolded rib 314 is shown. Incoming air first impacts the rear wall 318 of the frame, and then the rib 314 guides the air into the eyeglasses. Figure 15 It shows Figure 14 The image shows a cross-sectional view of the eyeglass assembly taken along line BB.

[0051] Figure 16 It shows Figure 15 A close-up view of the cross-sectional view of the eyeglasses assembly shown. Figure 16 The airflow path is also depicted. Here, it can be understood that the air first impacts the rear wall 318 of the vent 310. If the rib is absent, the air will follow the natural curve of the lens (shown by arrow 501). If the rib is present, the air will be guided in a controlled manner and will enter the eyeglasses accordingly (described by arrow 402).

[0052] It is understood that the multi-directional vent 310 preferably does not allow air to enter the area behind the lens in a straight path. Airflow is guided through the recess and may not follow a straight path. For example, vent 310 allows air to enter the recess via a horizontal path 402, and then the air is guided into the area behind the lens due to the shape of the ribs. Ribs allow air to be guided in a specific manner. Furthermore, ribs can be shaped such that airflow is guided to areas behind the lens that require more ventilation. For example, ribs can be angled acutely toward the nose to ventilate the area near the nose more than other areas. Thus, the shape of the provided ribs can be changed and airflow guided as needed. It is understood that by using a greater number of ribs, the ability to redirect airflow in multiple different directions increases.

[0053] When there are no ribs in the vent, the lens recess and frame recess together form a substantially horizontal channel section and a substantially vertical channel section that are fluidly connected to each other. When there are ribs in the vent, there is additional obstruction in the vent. This allows for the formation of an "indirect" or L-shaped ventilation channel that extends through the frame structure. Therefore, the "indirect" or L-shaped ventilation channel has an opening on the front side of the frame and an opening on the rear side of the frame. The ribs can alter the ventilation channel and thus affect airflow. Therefore, the "indirect" or L-shaped ventilation channel with ribs allows for effective humidification and air circulation while preventing foreign particles passing through the ventilation channel from entering the user's eyes and impacting the user's face.

[0054] Figure 17 A front view of the frame of the eyeglass assembly is shown, illustrating the rib 314 incorporated into the multi-directional vent 310. Figure 18 A top view of the eyeglass assembly is shown, illustrating the rib 314 incorporated into the multi-directional vent 310.

[0055] Figure 18 A top view of an eyeglass assembly with vents 310 and ribs 314 present in the vents is provided. In this embodiment, it can be understood that air enters each of the vents 310 from different directions. The vents are angled, which allows airflow to fully enter the area behind the lens and ventilates the lens in a controlled, directional manner. Figure 19 yes Figure 18 The front view of the eyeglasses assembly shown.

[0056] Figure 20 A close-up view shows the ribs and overmolded portions integrated into the multi-directional vent. It can be understood that multiple ribs and details can exist within a single ventilation channel. Figure 20 The first rib 314 and the second rib 320 are shown working in parallel to redirect air into the interior of the eyeglasses.

[0058] A method for manufacturing eyeglasses with multi-directional ventilation openings is also provided. Multiple lens recesses 201 may be formed on lens portions 202. The lens recesses 201 may be formed using CNC machining or by injection molding of the lens portion 202 with the recesses 201, or similar methods known in the art. A bridge portion 203 may be formed separately from the pair of lens portions 202a and 202b. Multiple frame recesses 301 may be formed on frame portions 302. The frame recesses 301 may also be formed using CNC machining or by injection molding of the frame portion with the recesses 301. The frame portion may be connected to the lens portion, aligning the lens recesses 201 with the frame recesses 301, and forming ventilation openings 310. The step of forming the lens recesses 201 includes cutting the lens recesses such that the lens recesses are angled in multiple directions. The step of forming the frame recesses 301 includes cutting the frame recesses 301 such that the frame recesses 301 are angled in multiple directions.
