Description

[Technical field]

[0001] The present invention relates to an eyeglass support that can be easily attached to and detached from the strings of ordinary eyeglasses or sunglasses and has the function of changing the eyeglass support into one that supports the eyeglasses themselves at the temples of the eyeglass wearer. [Background technology]

[0002] The structure of most typical eyeglasses and sunglasses is such that they are attached to the wearer's face at three points: the nose pads (nose pads) located in the center of the front part where the eyeglass lenses are located, and the earpieces (earpieces) that extend from the temples attached to both ends of the front part. As the front part accounts for most of the weight of the eyeglasses themselves, the weight is concentrated on the nose pads, which can cause discomfort and pain when worn for long periods of time, and many users are plagued by problems such as the nose pads leaving marks on the skin.

[0003] In addition, people who wear glasses or sunglasses often have to deal with fogging of the lenses caused by exhaled air leaking out of the top of the mask when wearing a mask to prevent infectious diseases or hay fever. However, the current mainstream method of preventing fogging involves applying a chemical to the lenses, and there are few other options.

[0004] One of the causes of lens fogging is thought to be the narrow space between the lens and the face, and the fact that the nose pad in the center of the front part comes into contact with the nose, blocking the airflow, which makes it easy for exhaled air leaking out from the top of the mask to become trapped.

[0005] In recent years, while nose pads remain mainstream, there have been some inventions that attempt to solve the drawbacks of nose pads, such as eyeglass frames without nose pads, and the use of auxiliary devices for regular eyeglasses and sunglasses, but these have not yet become widespread. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] JP 2020-144290 A [Patent Document 2] JP 2022-157383 A [Patent Document 3] Patent Publication No. 2022-51631 [Patent Document 4] Patent No. 5876531 [Patent Document 5] JP 2020-101795 A [Patent Document 6] JP 2018-194643 A Summary of the Invention [Problem to be solved by the invention]

[0007] In Patent Document 1, the type of string that can be clamped is significantly limited, the clamping device is exposed, which makes it aesthetically unsightly, and the contact area with the temple is small, so the load on the temple is concentrated in a small area of ​​the temple, which raises concerns that it may cause discomfort and pain similar to that of nose pads, and may even leave pressure marks on the skin.

[0008] In Patent Document 2, in addition to the fact that the support itself is large, the band at the fixing part is exposed, which makes it aesthetically unsightly. Furthermore, because it is attached close to the ear hook of the string, the fixing part touches the ear, raising concerns about the wearing comfort.

[0009] The patent documents 3 and 4 are based on the concept of attaching a device that presses the mask itself to glasses with the aim of preventing breath leakage from above the mask in order to prevent glasses from fogging up, and are therefore inventions as a countermeasure against fogging of glasses lenses. However, from the standpoint of appearance it seems unlikely to become widespread, and regardless of whether a mask is used, it has no effect as a countermeasure against fogging of nose pads, and therefore their direction is different from that of the present invention.

[0010] In Patent Document 5, the contact pad cannot be attached to or detached from the eyeglasses, and is therefore not convenient. In addition, the contact area with the temples is small, so a strong load is placed on the temples, raising concerns that the contact pad may cause discomfort, pain, and pressure marks, similar to those caused by nose pads.

[0011] In Patent Document 6, there are doubts about the attachment / detachment and fixation to various strings, as well as the strength of the temple support. Furthermore, since the contact area with the temple is small, a strong load is placed on the temple, and there are concerns that discomfort, pain, and pressure marks may remain, similar to those caused by nose pads.

[0012] As described above, the problem to be solved is to provide an eyeglass support that aims to solve the problems common to existing eyeglass wearers, can be easily attached and detached to ordinary eyeglasses and sunglasses, is compatible with a variety of eyeglass string shapes, firmly supports the eyeglass body at the temple, reduces discomfort and pain caused by increased load on the temple contact area and pressure marks as much as possible, has a freedom of design that does not impair the aesthetic appearance when worn, and has a simple structure and uses ordinary materials, making it easy to disseminate widely and has excellent cost performance. [Means for solving the problem]

[0013] In order to solve these problems, the present invention provides an eyeglass support that is composed of two main parts: a base that can be easily attached and detached from each string of the eyeglasses, and temple pads that have appropriate adhesive strength and flexibility and that gently press against the base and the wearer's temples.

[0014] The base is composed of an outer cover that clamps and encases the strings, a fastener that closes and secures the outer cover, and a part inside that called an inner adjuster that functions as the key to adjusting the string clamping position.

[0015] The inner adjuster has two main adjustment functions: one is to use the internal pressure of the outer cover to firmly clamp and fix the string without loosening, and the other is to change the position at which the string is clamped inside the base to appropriately adjust the thickness of the base body located in the space between the string and the temple (this is called the temple clearance).

[0016] The temple pads are made of an easily available material that is flexible, slightly sticky, and has a suitable area and thickness; they come into contact with the side of the base attached to the string that is closest to the head, becoming one with the base and the string, and applying moderate pressure to the temples to lock the eyeglasses into place. However, because the adhesive force is also exerted on the skin at the temples, the eyeglasses can be firmly and comfortably supported at the temples without the string and support device pressing too hard against the temples.

[0017] If the temple pads were not adhesive, the support would be held in place solely by pressure from the head, which would not only place strain on the strings of the glasses but also place a great deal of strain on the user's temples where they come into contact; therefore, the adhesiveness of the temple pads is essential for comfortable temple support. Effect of the Invention

[0018] According to the present invention, it is possible to support the temples of existing general eyeglasses or sunglasses, so that the front part of the eyeglasses can be used in a state where it is lifted above the nose.

[0019] This makes it possible to adjust the mask to have a larger space between the mask and the front of the glasses and the face when worn, making it easier to diffuse exhaled air leaking out from the top of the mask, which has the effect of preventing fogging of the glasses lenses caused by trapped exhaled air.

[0020] In addition, even if the lens does fog up, the inside of the front lens is more easily exposed to outside air, reducing the amount of trapped exhaled air, which helps the fogging clear up faster.

[0021] Not only that, but because the nose pads do not come into direct contact with the skin around the nose, the discomfort and pain caused by the nose pads, as well as the problem of the nose pads leaving marks on the skin, are completely eliminated.

[0022] On the other hand, in the temple area, which supports the weight of the spectacles in place of the nose pads, the excellent properties of the temple pads make it less likely that discomfort, pain, or pad marks will be caused by pressure at the temple contact points.

[0023] The eyeglasses support of the present invention as described above can be realized by using a simple structure and easily available materials, and therefore has a high price advantage, which is an important factor for its widespread use.

[0024] Furthermore, with regard to the appearance, there are no restrictions on the design as long as the necessary conditions are met, such as the attachment of fasteners to the outer cover, the provision of inner adjusters, ensuring a good contact surface for the temple pads, and the appropriate hardness of the outer cover itself. Therefore, it is not only practical as an eyeglass support, but also possible to provide diverse value to a variety of targets as an accessory that brings new appeal to existing eyeglasses.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0026] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings, in which the same reference numerals are used to refer to the same components throughout the drawings.

[0027] (Overall composition) As shown in Figs. 1 and 2, the eyeglass support of the present invention is composed of a pair of bases 7 that can be easily attached and detached to the left and right strings 3 of existing eyeglasses 1 or sunglasses, and temple pads 8 on the outer surface of each base 7 facing the user's head that have flexibility and adhesiveness to enable easy attachment and detachment, and that play a role in engaging the support by softly contacting the wearer's temples.

[0028] The basic configuration is limited to the above two points, but existing eyeglass strings have various shapes, heights, and thicknesses, and the base 7 shape shown in Figures 7, 18, and 20, which can be attached and detached to various strings 3 except for special shapes, is described in detail below as the basic structure. In addition, a base 7 shape shown in Figure 25, which pursues miniaturization as a limited application for thin strings made of ferromagnetic material, will also be described later as an application example.

[0029] The shapes, materials, and arrangements of these components are shown as examples of basic components, and as long as they have the necessary functions, they are not limited to the contents described in the embodiments of the present invention.

[0030] (base) The base 7 in Figure 7 is shown to be composed of three elements: the outer cover 11, the fastener 9, and the inner adjusters 12 and 13. In the examples in Figures 8 to 17, the base 7 is shown to clamp and fix the strings 3 and set the temple clearance by covering and closing the outer cover 11 with the fastener 9 while changing the inner adjuster layer and adjusting the string placement for strings of different shapes and sizes.

[0031] The main roles of the base 7 are to firmly clamp and fix the strings 3 of various shapes without loosening, despite its simple structure; to adjust the temple clearance 23; and to take advantage of the adhesiveness of the temple pads and to be made of a structure and material that allows them to be easily attached and detached.

[0032] The base 7 is attached to the strings 3 of the glasses, and as shown in Figures 4 and 5, since it is noticeable when worn, appearance is important and a wide degree of freedom is required for its design, but there are no particular restrictions as long as it functionally fulfills the above roles.

[0033] A suitable material for the outer cover 11 must have the necessary thickness to hold the string 3 together with the inner adjuster and to engage it with the attached fastener 9, as shown in Figures 8 to 22, and must have a good balance of moderate flexibility and hardness.In addition, since the temple pads are attached to the outer side of the outer cover when in use to form a support, as shown in Figure 6, the material must have at least a smooth outer surface and must have the property of being able to be engaged by the adhesiveness of the temple pads alone.Mainly leather, synthetic leather, rubber, polyurethane, etc. are suitable, but there are no particular limitations on the material as long as it fulfills the required functions as a cover.

[0034] Fastener 9 may be of the type shown in 9 in Figure 7 that snaps into place like a typical spring hook or one-touch hook, or it may be of the commonly used fastener tape or a type that fits neatly inside the outer cover, such as magnet 16 shown in Figures 20 and 25. As long as the base can be easily attached and detached from the string and can clamp and secure the string without loosening, there are no limitations on its specifications or materials, and a variety of types can be created depending on the design of the base itself.

[0035] The inner adjuster plays an important role in clamping and fixing strings of various shapes and sizes inside the outer cover without loosening, as well as adjusting the temple clearance. To maximize its effectiveness, the inner adjuster incorporates the concept of a variable layer, while being made of commonly available, inexpensive materials and having a simple structure.

[0036] First, the inner adjuster in Figure 7, which is a representative example, is made by fixing part of the edge of a single sheet of flat material near the fastener 9 at the bottom of the figure, and leaving the rest of the material loose and cutting it to create three tongue-like portions, the two on the outside are the outer tongue-like portions 12 of the inner adjuster, and the other is cut a little shorter on the inside to take into account interference with the fastener and becomes the inner tongue-like portion 13 of the inner adjuster.

[0037] FIG. 8 shows the state in which the inner adjuster is not folded but is instead placed along the outer sheath to fit the shape of a relatively large and thick string 3, with the string placed on top of it. FIG. 9 shows the state in which the outer sheath is then clamped together and the fastener is fitted.

[0038] In this case, there are two layers inside the outer cover, one below the string 3 and one above it. If the string 3 is clamped and fixed tightly, the inside of the outer cover will be filled with the string and layers, creating a high pressure state, which indicates that the string clamping adjustment is working properly.

[0039] If the pressure is too weak, the string will loosen, so it is necessary to fold the layers as shown in Figure 12 to increase the thickness of the layers and expand the cross-sectional area of ​​the layers inside the outer cover. Conversely, if the pressure is too strong, the outer cover will not close, so by making adjustments such as reducing the number of layers, the string can be clamped and fixed appropriately.

[0040] Also, temple clearance 23 in Figure 9 represents the distance from under the string 3 to the skin at the temple where the tip of the temple pad comes into contact; in this example, this distance is represented by the thickness of one layer of inner adjuster + outer covering + temple pad; if one layer of inner adjuster is 1mm thick, the thickness of the outer covering is 1mm, and the thickness of the temple pad is 3mm, then the temple clearance is 5mm in total.

[0041] The skin at the human temples is quite soft and when the temple pads are pressed against it there is a certain amount of depression, so it is necessary to set the temple clearance slightly longer than it appears; however, the degree to which the skin depressions varies greatly from person to person, and as shown by the long and short temple clearances 24 and 25 in Figure 32, even for the same person and the same string, the temple clearance will change slightly depending on the position of the support attachment, so the ability to adjust this temple clearance is extremely important for stable and comfortable support at the temples.

[0042] In Figure 10, the string 3 is the same size as in Figure 8, but with the intention of setting the temple clearance longer than in Figure 9, all of the tongue-like parts of the inner adjuster are folded short and the string 3 is placed on top of them. In Figure 11, this is shown clamped together with the outer cover and the fastener is attached. In this case, the layers inside the outer cover are a total of two layers, just like in Figure 9, but there are two layers below the string 3 and none above. As a result, the temple clearance 23 is two layers of inner adjuster + outer cover + temple pad, which indicates that it is one layer of inner adjuster longer than in Figure 9.

[0043] In Figure 12, to accommodate a string 3 with a smaller cross-sectional area than in Figure 10, only the tongue 13 located in the middle of the inner adjuster is folded shorter, and the string 3 is placed on top of it, and in Figure 13 the outer tongue 12 and the outer cover are clamped together and a fastener is fitted. In this case, there are three layers inside the cover, two layers below the string 3 and one layer above it, and the cross-sectional density of the inner adjuster is increased to firmly clamp and fix the thin string 3, but the temple clearance 23 is the two layers of inner adjuster + outer cover + temple pad, and is the same distance as in Figure 11.

[0044] Figure 14 shows how all of the tongues of the inner adjuster are folded short to accommodate a string 3 with an even smaller cross-sectional area than that of Figure 12, and then both folded outer tongues 12 are lifted up, with the string 3 placed and clamped on top of the middle tongue 13. Figure 15 shows the outer cover in place with a fastener, but in this case there are four layers inside the outer cover, two below the string 3 and two above it, further increasing the cross-sectional density of the inner adjuster to firmly clamp and fix the thin string 3, but the temple clearance 23 is the two layers of inner adjuster + outer cover + temple pad, and is the same distance as in Figure 13.

[0045] Figure 16 shows the same string 3 as in Figure 10, but in order to further reduce the temple clearance, the inner adjuster with all of the tongues folded short is lifted up and the string 3 is placed between it and the outer cover underneath. Figure 17 shows the outer cover fitted with a fastener. In this case, there are a total of two layers inside the outer cover, which is the same as in Figure 11, but with 0 layers below the string 3 and 2 layers above it, the temple clearance 23 is 0 layers of the inner adjuster + outer cover + temple pad, which shows that it is the shortest temple clearance among the example figures.

[0046] As described above, the concept of the variable layer is simple: by adding the cross-sectional area of ​​the inner adjuster, which can be freely adjusted as a layer, to the cross-sectional area of ​​strings of various shapes and sizes, the pressure inside the outer cover is increased, and the string is clamped and fixed without loosening.

[0047] The material that the inner adjuster is made of should be thick enough and flexible enough to be folded, yet hard enough so that the string it holds does not wobble. Suitable materials include leather, synthetic leather, rubber, and urethane, but other materials can also be used as long as they meet the requirements for functionality and cost-performance.

[0048] In addition, regarding the shape, a type having a tongue-shaped portion has been described in detail as an example, but there are no particular restrictions as long as it has a similar function, and it does not necessarily have to be fixed to the outer cover, and Figures 18 to 22 show an example of an unfixed inner adjuster.

[0049] The inner adjuster 14 in FIG. 18 is a flat material folded into a bellows shape, or a pad-like material connected in a bellows shape. It is not fixed to the outer cover 11, but the number of layers is adjusted by cutting the bellows according to the shape and size of the string, and the cross-sectional area is adjusted by the thickness of the layers.

[0050] In Figure 19, a thin string 3 is placed in the middle of the accordion-type inner adjuster 14 that is folded in four as in Figure 18, and this is sandwiched in the outer cover 11. The layers inside the outer cover are two layers above and below the string 3, for a total of four layers, and the temple clearance 23 is two layers of inner adjuster + outer cover + temple pad.

[0051] In this way, even with a bellows-type inner adjuster, the concept of adjusting the cross-sectional area inside the outer cover and adjusting the temple clearance by using the variable layer remains unchanged, and as with the materials mentioned above, there are no particular restrictions as long as they have the same functions and elements.

[0052] Next, FIG. 20 shows an example of a type in which the fastener is a magnet 16 and a fastener 17 made of a ferromagnetic material that receives it. This type of fastener has a structure in which the fastener structure can be designed so that it does not appear on the outside of the outer casing, which has the advantage that it further increases the design freedom of the outer casing itself, and also makes it possible to use a bellows-type inner adjuster and, depending on the size of the magnet, to make a smaller, slimmer base.

[0053] The example in Figure 21 shows a bellows-type inner adjuster similar to that in Figure 18, with one layer of the four-fold outer bellows cut and the three-fold outer bellows wrapped around a thicker string 3 in order to adjust it to the shape and size of the string 3. Figure 22 shows an example in which a thin string 3 is placed between the top two layers of the four-fold outer bellows-type inner adjuster.

[0054] In this way, the bellows-type inner adjuster has a simple structure, but if you prepare one that is small but has the maximum density inside the outer cover, you can adjust the string placement while reducing the number of bellows layers depending on the cross-sectional area of ​​the string to be attached, which will allow you to easily and stably clamp the string and adjust the temple clearance, thereby achieving comfortable temple support.

[0055] Figures 23 and 24 show these glasses supports with magnet-type fasteners and bellows-type inner adjusters attached to glasses, and it can be seen that they have a slimmer shape than the types shown in Figures 2 and 3.

[0056] As an example of an application of the base, in pursuit of even further miniaturization, the inner adjuster and fastener functions of Figure 25 are integrated into a magnet 16. The strings that can be clamped are limited to those that are thin and made of ferromagnetic material, but in one type, the string 3 is placed directly on the magnet as shown in Figure 26, and the outer cover 11 and string 3 are then tightly attached to each other by magnetic force as shown in Figure 27.

[0057] In this type, the magnet simultaneously adheres to the ferromagnetic string 3 and the ferromagnetic fastener 17 provided on the outer cover 11, so the inner adjuster is omitted and the base structure is greatly simplified, making it possible to achieve a compact size.

[0058] Regarding the temple clearance adjustment that can be performed within this type of base, in Figure 27 there are only two patterns: a long pattern indicated by 24, which is a magnet + housing 7 + solid temple pad 8, and a short pattern indicated by 25, which is a ferromagnetic fastener 17 + housing 7 + dotted temple pad 8, where the temple pad is moved and attached to the other side of the housing.Compared to the type with an inner adjuster, the range of adjustment is narrower, but it is possible to effectively adjust the temple clearance by switching to a thin magnet and increasing or decreasing the number of magnets in layers, or by increasing or decreasing the thickness of the temple pad.

[0059] The multi-magnet fastener type base that makes this compact size possible has the appealing feature of being able to achieve an extremely slim design, as shown in Figures 28 and 29. Even if a string is wide enough to protrude from the base, it can still be clamped and fixed by the magnets, so long as it is a thin, ferromagnetic string. It is therefore anticipated that the range of strings that can be used will not be limited at all.

[0060] However, even though it is compact, in order to firmly clamp and fix the string 3 and to maintain the area required to distribute the pressure of the temple pad 8 and prevent pad marks from being left, it is necessary to extend it horizontally along the string to ensure a minimum area as an eyeglass support.

[0061] Regarding the structure and design of this miniaturized specification, it is attractive that it is not only possible to use a type in which the outer cover is folded to cover the device, but also to divide the outer cover and use a ferromagnetic lid-like outer cover that is attracted by a magnet, and that as long as the basic role of the base is fulfilled, it is possible to create a variety of shapes and designs by taking advantage of the properties of the magnet.

[0062] An even more extreme application example would be one in which a magnet is directly attached to the inside of a ferromagnetic string, as shown in Figure 34, and the temple pad is then abutted against it. In this type, the magnet integrates the outer covering on the magnet side and combines with the temple pad, making it possible to realize a minimalist type in which no covering appears on the outside of the string.

[0063] In this case, temple clearance adjustment is restricted by the thickness of the temple pads, and temple clearance shorter than the thickness of the magnet cannot be accommodated. However, there is nothing added to the outside of the string, and with a particularly wide string, the magnets and temple pads present on the inside are also hidden, and the only materials used are the magnets and temple pads, so the price advantage is overwhelmingly high, making it an attractive product and it can be proposed as a stealth eyeglass support that is minimal in both size and price.

[0064] (Temple pad) The temple pad 8 is a rectangular cushion-like pad that is adhesive and flexible, and can be attached to the base 7 on one side of the outside using only its adhesive force without the use of adhesive or the like, as shown in Figure 6, and can also be easily removed.

[0065] The side of the temple pad 8 opposite the contact surface with the base 7 becomes the contact surface with the temple of the eyeglass wearer, and the adhesive strength of the temple pad not only enables it to be firmly attached to the temple without the need for strong pressure, but another excellent characteristic of the temple pad is that it can be easily removed from the skin without leaving any adhesives or medicines on the skin.

[0066] In addition to the cushioning effect due to its flexibility, the area that comes into contact with the skin at the temples is wide, not just a point, which distributes the pressure of the eyeglass support, reducing discomfort, pain, and pad marks when in use.

[0067] Although the temple pads 8 will need to be replaced due to deterioration after long-term use, as they are not attached to the base, they can be easily removed and the pads themselves can be washed. This is not only hygienic as it allows sebum and other dirt to be easily removed, but also has the effect of suppressing deterioration of adhesive strength, and is economical as it is made of a commonly used and easily available material.

[0068] The temple pad material that exhibits the above-mentioned excellent properties is polyurethane, and in particular a material called urethane gel, which has been shown to be effective in prototypes. However, there is no problem with using other materials as long as they can be used on the skin without causing any problems, have similar properties and functions, and are also more cost-effective.

[0069] The shape is based on a rectangular prism that ensures a sufficient flat area on one side of the base when closed, but as long as it has a wide surface rather than a narrow point and can adequately distribute the load on the skin, there is no problem with freely adopting a shape to match the outer covering.

[0070] Furthermore, taking into consideration sinking of the pad due to the softness of the skin at the temples, the effect of dispersing pressure on the skin contact surface, and the need for temple clearance adjustment, a thickness of around 2 to 5 mm is desirable, and because the pad itself has adhesive properties, thickness can be easily adjusted by stacking thinner temple pads. For example, stacking up to three 2 mm thick temple pads can create three levels of pads with thicknesses of 4 mm, 2 mm, and 6 mm. This type of application is possible even if the adjustment range of the temple clearance as a base is narrow, such as in the base type without an inner adjuster in Figure 25.

[0071] Furthermore, by chamfering the vertices and edges of the cube to make them rounded, it is expected that the pads will leave fewer marks on the skin.

[0072] (Attaching the base to glasses) When attaching it to eyeglasses, it is important to clamp and fix strings of various shapes without loosening, and to properly adjust the position of the base to match the distance between the wearer's temples and the strings, i.e., the temple clearance.

[0073] As mentioned above, the inner adjuster plays a major role in how the base clamps and fixes the string. Although the structure itself is simple, it can accommodate strings of a variety of shapes and sizes, although it cannot accommodate strings that are larger than the space inside the base enclosed by the outer cover. It can be attached and detached to most existing glasses and sunglasses.

[0074] Also, the magnet type in Figure 20 uses an inner adjuster, but just like the specifications in Figure 25, if the string is a thin, ferromagnetic string, it is possible to omit the inner adjuster and simply clamp the string with a magnet.The string is simply pressed down tightly by the outer sheath and magnet, and due to its structure, it is possible to clamp and fix even wide strings that protrude from the outer sheath, which has the advantage of allowing a wider range of strings to be handled.

[0075] As shown by 24 and 25 in Figure 32, even for the same eyeglass wearer, the distance between the temple and the string changes depending on the installation position of the eyeglass support. The distance is longer at temple clearance 24 located on the right side closer to the front, and shorter at temple clearance 25 located on the left side closer to the ear hook.

[0076] For this reason, in FIG. 32, when the same eyeglass support is attached to the temple clearance positions shown by the different positions 24 and 25 of the string, this space must be appropriately filled with the base head side and temple pads. In this example, the same temple pads are used, but the position where the string is clamped within the base is changed. For example, the base 7, which has a short temple clearance 25, has a short distance between the string and the temple, so the base closer to the temple is set shorter to clamp the string, as shown by temple clearance 25 in FIG. 27. Conversely, the base 7, which has a long temple clearance 24, has a longer distance between the string and the temple than 25, so the base closer to the temple is set even longer to clamp the string, as shown by temple clearance 24 in FIG. 27.

[0077] As mentioned in the section on temple pads, if the temple clearance cannot be adjusted appropriately simply by changing the position where the strings are clamped inside the base, you can adjust it by stacking temple pads or using thinner or thicker temple pads.

[0078] (When the user is wearing glasses with the glasses support) Wearing the eyeglasses with the eyeglass support attached is the same as wearing regular eyeglasses, but as shown in Figures 4, 5, 30, 31 and 33, the eyeglass support is positioned at the user's temple, and the appropriate pressure from the eyeglass support and the adhesiveness of the temple pads lightly adhere to the temple, using this point as a fulcrum to support the entire eyeglasses.

[0079] Since the temple clearance differs depending on the shape of the head and glasses of each user, and also on the attachment position of the base, it is necessary to adjust and optimize it; however, in this case, if the base 7 is moved too close to the ear hooks of the glasses, the weight of the front part 5 of the glasses will cause it to drop, and the nose pads may touch the nose. On the other hand, if the base 7 is moved too far towards the front in order to lift the front part 5, the temple clearance will become too wide and the temple pads will not reach, resulting in insufficient support for the temples of the glasses, or the temple pads will be positioned so as to cover the sides of the eyes, making for an uncomfortable fit.

[0080] For this reason, it is essential that the eyeglass support be easy to attach, detach, and move, and that adjustment for positioning can be easily performed.

[0081] In Figures 4, 30, and 31, the nose pads and nose space 15 achieved by attaching the eyeglass support can be seen, and it is clear that the ventilation between the front part and the face space has improved.

[0082] As shown in FIG. 31, if the ear hooks of the mask 10 are placed not only on the ears but also on the ear hooks 4 of the glasses, a force is applied downward on the ear hooks 4 using the glasses support as a fulcrum, which has the effect of preventing the front part 5 of the glasses from easily dropping due to its weight. This is an effective device for glasses wearers who are troubled by the lenses fogging up when wearing a mask.

[0083] FIG. 33 shows a shape in which a glasses strap is attached to a support, which is an example of the high degree of freedom in design. [Explanation of symbols]

Claims

1. This is a small eyeglasses support device that can be easily attached and detached to the strings of ordinary eyeglasses or sunglasses, and is composed of an outer cover with a fastener, a base with an inner adjuster processed to be easily multi-layered inside in order to freely adjust the method and position of clamping the string, and a temple pad made of a flexible material with moderate adhesiveness that abuts against the base and the temple of the eyeglass wearer.

2. This eyeglass temple support has the basic functions of the eyeglass temple support described in claim 1, but is made smaller by integrating the inner adjuster function and the fastener function with a magnet, or by having a magnet also serve as the temple pad abutment function of the outer covering.
