Description

Technical Field

[0001] The present invention relates to a support device for use with glasses, and more particularly, to a cam for fixing glasses to reduce the weight of the glasses and avoid excessive squeezing of the nose. Background Art

[0002] Devices for assisting vision have been used since ancient times. In the second century AD, Ptolemy wrote a treatise on optics, which included descriptions of reflection and refraction. Although classical knowledge has been lost, some progress has been made in the science of optics in medieval Europe. The translation of Arabic works further improved the art, and by the late Middle Ages, glasses had appeared in Europe.

[0003] Around the 18th century, glasses began to take on their present form, especially the cams that help support the glasses on the wearer's face. Modern glasses benefit from advances in materials science, resulting in lightweight frames and lenses. Nevertheless, glasses still add at least a few ounces of weight to the nose, and people who wear glasses regularly sometimes complain that wearing glasses can cause nose discomfort, redness, or indentation. Therefore, there is still a need for a device that can allow the use of traditional glasses without the discomfort caused by contact with the wearer's nose. Summary of the Invention

[0004] To solve the existing problems, the present invention aims to provide a temple rod cam for supporting glasses. To achieve the above object, in the technical solution adopted by the present invention, temple rod cams are respectively provided on the left and right temple rods of the glasses, and a temple rod receiver for the temple rod to pass through is provided on the temple rod cam; a cam lobe is formed after the side of the temple rod cam close to the face is squeezed; the temple rod cam is supported by the user's face and holds up the glasses.

[0005] Wherein, a through conical hole is provided in the middle of the temple rod cam. The conical hole has a conical funnel shape similar to the shape of the temple rod cam body, so as to maintain relatively uniform deformability within the entire length range of the temple rod cam.

[0006] Wherein, the temple rod cam is in a conical shape.

[0007] Wherein, the cam lobe of the temple rod cam close to the face is in a hook shape or a beak shape, and the shape provides a concave surface. A concave surface similar to that provided by the conical hole to the temple rod cam is provided.

[0008] Wherein, the cam lobe of the temple rod cam extends from the temple rod receiver in a C-shaped configuration. The concave inner surface of the C-shaped cam lobe provides a certain degree of flexibility.

[0009] Wherein, the temple rod cam is in an L shape, and the "L" is composed of a vertical line segment and a horizontal line segment.

[0010] Among them, the cam lobe of the temple rod cam has a long and slightly curved shape.

[0011] Among them, the temple rod cam has a shoe-shaped cross-section, there are two apertures on the cam lobe, and the temple rod receiver is inside the shoe shape. The apertures and the temple rod receiver extend from the front to the back of the temple rod cam.

[0012] Compared with the prior art, when used in pairs, the present invention is used to support a pair of glasses, so that the nasal septum of the glasses is kept above the wearer's nose. There is a temple rod cam on the temple rod of each pair of glasses; when the glasses are worn on the wearer's face, the temple rod cam will rotate to the wearer's temple, stop the glasses from moving downwards, and fix the glasses at a position above the wearer's nose;

[0013] For the comfort of the wearer, the temple rod cam can be made of a soft, elastic and non-toxic material, such as medical silicone;

[0014] The conical frustum shape of the temple rod cam further enhances the comfort of the wearer, and the holes extending through each temple rod cam are for increasing the deformability of the temple rod cam shape. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The present invention will be further described below in conjunction with the accompanying drawings.

[0042] First, refer to Figure 1 , which shows a pair of temple rod cams 100 in use. A glasses wearer (user) 102 is wearing glasses 110. Although the glasses 110 are shown to demonstrate the operation of the temple rod cams 100, the glasses 110 are representative, and the temple rod cams can be used with other glasses having a similar structure, such as 3D glasses, goggles, color correction glasses, plain glasses, and other similar instruments. The glasses 110 include a nose bridge 112, which is generally supported by the nose of the user 102, so that most of the weight of the glasses 110 is on the nose 104 of the user 102. However, a temple rod cam 110 is attached to each of the left temple rod 114 and the right temple rod 116. Each temple rod cam 100 is supported by the face of the user 102 to hold up the glasses 110 so that no additional weight is added to the nose 104. Since a pair of glasses has two temple rods, it is normal to use two temple rod cams 100 simultaneously, one cam for each temple rod.

[0043] In the preferred case, the temple rod cam 100 is made of silicone rubber, which has high elasticity so that the temple rod cam 100 can deform as described below during use and return to its original shape after use. In the first case, the silicone rubber used is medical-grade silicone, so that it will not cause discomfort or adverse reactions to the skin of the user 102 in contact with the temple rod cam 100 during use.

[0044] Now refer to Figure 2 , which describes the use of a temple rod 100. The temple rod cam 100 is attached to the left temple rod 114 of the glasses 110 (as Figure 1As shown). Broadly speaking, the temple bar cam 100 is a deformable body having a temple bar receiver 124 sized to receive the temple bars 114 of a pair of glasses 110. When the left temple bar 114 passes through the temple bar receiver 124, the body deforms to form cam lobes 142 and 144 contiguous with the temple bar receiver 124 (as Figure 4 described). The temple bar cam 100 on the right temple bar 116 functions similarly along the right side of the user 102's face and is not described separately. Once deformed in this way, the other parts of the body assume the shape of cam lobe 120 relative to the temple bar receiver 124.

[0045] When the glasses 110 are placed on the user's face, since the glasses 110 are connected to the user's ears and are relatively lower with respect to the user's nose, the temple bar cam 100, which is slightly above the nose 104, rotates and deforms in the direction 118. The rotation of the glasses 110 towards the user's nose causes the cam lobe 120 of the temple bar cam 100 to contact the user's face on one side and compress in the rotation direction 118 until the temple bar cam 100 secures the glasses 110 on the user's temples. The conical hole 122 in the temple bar cam 100 allows the temple bar cam 100 to deform sufficiently so that the temple bar cam 100 can comfortably rest between the left temple bar 114 and the user 102's face.

[0046] See Figure 3 , the left temple bar 114 and the user 102's face continuously exert pressure on the temple bar cam 100, which is fixed and in turn holds the glasses 110 on the user 102's nose 104, as shown by arrow 130. This creates a small gap 132 between the nose bridge 112 and the user 102's nose 104. Thus, the nose bridge 112 does not exert pressure on the user 102's nose 104 and does not cause irritation, redness, or indentation on the nose.

[0047] See Figure 4 , when the glasses 110 are worn, between the left temple bar 114 and the user 102's face, where the cam lobe 120 is drawn, the temple bar cam 100 moves in the direction shown by arrow 140. Thus, the glasses 110 are fixed in their intended positions. Also visible in Figure 4 are the cam lobes 142 and 144, which are formed by parts of the temple bar cam 100 protruding. The cam lobes 142 and 144 are created when the temple bar passes through the temple bar receiver 124.

[0048] Now as in Figure 5AAs shown, when a temple bar, such as the left temple bar 114, passes through the temple bar receiver 124, the temple bar cam 100 assumes a cross-sectional shape with a circular appearance and has a tail where the temple bar 114 passes through. The tail corresponds to Figure 4 the cam lobes 142 and 144 shown in Figure 1 . The remaining circular portion of the temple bar cam 100 explains the action of the cam lobe 120 in stopping the downward movement of a pair of glasses 110 (as shown in

[0049] As shown in Figure 5B , once the glasses 110 (as shown in Figure 1 ) are placed on the face of the user 102 and the glasses 110 start to lower to their rest position, the contact between the temple of the user 102 and the cam lobe 120 of the temple bar causes the cam lobe 120 to deform by rotating inwards towards the face. The elasticity of the temple bar cam 100 facilitates the inward rotational movement, which allows it to deform in shape as it continues to move downward with the temple bar 114. As shown in Figure 5C , due to the deformation of the temple bar cam shape, the temple bar 114 is finally positioned on one side of the cam lobe 120, opposite to the face of the user 102. The shape of the cam lobe 120 is deformed from its original circular shape, which is achieved through the elasticity of the temple bar cam 100 and the presence of the conical hole 122 to avoid discomfort to the user 102. At this time, the rotational movement and deformation of the cam lobe 120 stop, and the temple bar 114 no longer continues to move downward, but it is fixed in place by the temple bar cam 100.

[0050] Now as shown in Figure 6 , at the upper part or "top" 150 of the base (as shown in Figure 8 ), the diameter is smaller than that of the lower part or "bottom" 152 of the base (as shown in Figure 7 ). In a preferred case of the temple bar cam 100, it has a conical funnel shape and a circular cross-section instead of a temple bar. This conical funnel shape ensures contact between the temple bar cam 100 and the temple of the user 102 along the entire length of the temple bar cam 100. The conical hole 122 and the temple bar receiver 124 extend from the top 150 to the bottom 152, and in some cases, form part of the injection molding process for manufacturing the temple bar cam 100, while in other cases, they are cut into the temple bar cam 100 after the initial production of the conical funnel shape. In addition to the conical hole 122 and the temple bar receiver 124, in a preferred case, the aperture 154 extends from the side surface 156 to the temple bar receiver 124. In a preferred case, the aperture 154 has a rectangular shape, but other shapes can be used without departing from the present invention. The presence of the aperture 154 forms two strips 154A and 154B (as shown inFigure 11 As shown, these two strips are elastic and can be placed on the temple rods. The aperture allows the temple rods to more easily enter the temple rod receiver 124 of the temple cam 100.

[0051] Now refer to Figure 7 which illustrates, Figure 6 a bottom view of the temple cam 100 of Figure 7 showing the bottom 152, the conical hole 122 and the temple rod receiver 124. As Figure 8 shown, the conical hole 122 is also conical in the preferred case, with its narrow end at the top 150 of the temple cam 100 (as

[0052] Now refer to Figure 8 which illustrates, Figure 6 a right side view of the temple cam 100 of Figure 1 showing the side 156 tapering from the bottom 152 to the top 150. The conical hole 122 is not visible from this angle but is shown in dashed lines. It can also be seen that the temple cam 100 tapers from the bottom 152 to the top 150, however in the preferred case the temple rod receiver 124 maintains its diameter throughout. To use the temple cam 100, one temple rod of the glasses 110 (as Figure 1 ) is inserted through the temple rod receiver 124, into the bottom 152 and out through the top 150 so that when the glasses 110 are worn, the bottom 152 faces the front of the user 102's face (as

[0053] Now refer to Figure 9 which shows, Figure 6 a front view of the temple cam 100 of Figure 7 [[ID=!32]]showing the rectangular aperture 154. Unlike the conical hole 122 and the temple rod receiver Figure 7 (as Figure 4 shown), the aperture 154 does not extend from the bottom 152 to the top 150; instead, it is substantially centered between the bottom 152 and the top 150. This forms the cam lobes 142 and 144 (as Figure 7 [[ID=3!6]]shown), and the portions of the side 156 above and below the rectangular aperture 154 (as <00001`4>Now refer to Figure 10 which shows, Figure 6 a rear view of the temple cam 100 of Figure 7 The rectangular aperture 154 is shown in dashed lines as it only extends to the temple rod receiver 124 (as It should be noted that there seems to be some incorrect or incomplete tag references in the original text which might cause potential confusion in the translation. For example, in line 32, it says "Unlike the conical hole 122 and the temple rod receiver Figure 7 (as ", the tag reference seems incorrect. Also, in line 36, "as " is incomplete. But the translation is done based on the provided text as accurately as possible while following the given rules.As shown), it is thus not visible from the opposite side of the temple bar cam 100.

[0055] Now refer to Figure 11 , which shows a front upper perspective view of the temple bar cam 100 of Figure 6 . Here, the frustum shape of the temple bar cam 100 can be clearly seen, while the frustum shape of the conical hole 122 is shown by the dashed line. On the other hand, the shape of the temple bar receiver 124 is cylindrical. More specifically, in the preferred case, the temple bar receiver 124 is an oblique cylinder that maintains a constant distance between the center of its cross-sectional circle and the nearest edge of the side 156. In Figure 11 , the top 150 can be seen, showing the upper opening of the conical hole 122 and the temple bar receiver 124, which are approximately the same size.

[0056] Now refer to Figure 12 , which shows a lower rear view of the temple bar cam 100 of Figure 6 . The bottom 152 is visible, as is the lower hole of the conical hole 122 and the temple bar receiver 124. As can be seen from the figure, due to its frustum shape, the lower hole of the conical hole 122 is significantly larger than the lower hole of the temple bar receiver 124.

[0057] Now refer to Figures 13 to 24 , an alternative case of the temple bar cam has a different shape, which results in different degrees of difference in the deformability and degree of deformation of the temple bar cam. Both the deformation characteristics and the shape itself cause the temple bar cam to rest on the user's face in different ways. Therefore, a particular user may prefer a particular case over others.

[0058] Now refer to Figure 13 , which shows an alternative case of a temple bar cam, generally designated as 200. The temple bar cam 200 has a substantially cylindrical cam lobe 220 with a cylindrical hole 222 passing through its center. A temple bar receiver 224 with an elliptical cross-section projects from the cylindrical shape of the cam lobe 220. The front face 250 of the temple bar cam 200 is substantially similar in appearance to its back face (not shown), and both the cylindrical hole diameter 222 and the temple bar receiver 224 extend from the front face 250 to the back face. The hole diameter 254 on the side face 256 of the temple bar cam 200 is located on the protrusion and extends into the interior of the temple bar receiver 224.

[0059] Now refer to Figure 14 , the temple bar cam 200 is for placing a temple bar of a pair of glasses through the temple bar receiver 224. In other cases, when the user wears glasses, the cam lobe 220 (as in Figure 13The side that presses against the user's face prevents the glasses from resting on the user's nose.

[0060] Now refer to Figure 15 , which shows an alternative case of a temple bar cam, generally designated as 300. None of the cam lobes 320 of the temple bar cam 300 have a hole passing through it, but the hooked or beaked shape of the cam lobe 320 provides a concave surface, thus providing a flexibility similar to that provided by the conical hole 122 to the temple bar cam 200 (as shown in Figure 2 ), and the cylindrical hole 222 provided to the temple bar cam 200 (as shown in Figure 13 ). The temple bar receiver 324 projects from the beaked protrusion of the cam lobe 320 and, as in other cases, is a hole extending from the top surface 350 of the temple bar cam 300 to the bottom surface (not shown). The temple bar cam 300 also has a side 356.

[0061] Now refer to Figure 16 , the temple bar cam 300 is used by inserting the temple bar of a pair of glasses 110 into the temple bar receiver 324. In other cases, when the user wears the glasses, the cam lobe 320 presses against one side of the user's face, preventing the glasses from resting on the user's nose.

[0062] Now refer to Figure 17 , which shows an alternative case of a temple bar cam, generally designated as 400. In the temple bar cam 400, the cam lobe 420 projects from the temple bar receiver 424 in a C-shape. The front 450 and a substantially similar back form a C-shaped cross-section, surrounded by the side 456. As in other cases, the temple bar receiver 424 extends through the temple bar cam 400 from the front 450 to the back (not shown). The concave inner surface of the C-shaped cam lobe 420 provides a certain degree of flexibility for the deformation of the temple bar cam 400 during use.

[0063] Now refer to Figure 18 , the temple bar cam 400 is used by inserting the temple bar of a pair of glasses 110 into the temple bar receiver 424. In other cases, when the user wears the glasses, the cam lobe 420 presses against one side of the user's face, preventing the glasses from resting on the user's nose.

[0064] Now refer to Figure 19 , which shows an alternative case of a temple bar cam, generally designated as 500. The temple bar cam 500 is L-shaped. The letter "L" is formed by a vertical line segment (or "stem") and a horizontal line segment (or "leg"), perpendicular to the stem and extending to the right from the bottom end of the stem. The length of the leg is almost always shorter than the stem, and the corresponding parts of the temple bar cam 500 are no exception. InFigure 19 In it, the temple bar cam 500 is shown level with the valve stem as if the "L" has rotated 90° clockwise. The ends of the valve stem, the ends of the legs, and the intersection of the valve stem and the legs are all rounded. There is a concave edge between the intersection and the ends of the legs. The hole 522 is located at the end of the valve stem, while the temple bar receiver 524 is located at the end of the leg. Both the hole 522 and the temple bar receiver 524 extend from the front face 550 to the back face of the temple bar cam 500. The side face 556 extends along the perimeter of the L-shape.

[0065] In the temple bar cam 500, the shape of the hole diameter 522 is similar to that of the temple bar receiver 524, which gives the user a certain degree of flexibility because the functions of the hole diameter 522 and the temple bar receiver 524 can be interchanged. More specifically, according to the user's preference, the user can choose to insert a temple bar into the hole diameter 522 instead of placing a temple bar in the temple bar receiver 524, which brings different feelings to the user when using the temple bar cam 500.

[0066] Now refer to Figure 20 , the temple bar cam 500 has a temple bar of a pair of glasses 110 inserted into the temple bar receiver 524. Alternatively, the temple bar can pass through the hole diameter 522. In other cases, when the user wears glasses, the cam lobe presses against one side of the user's face, preventing the glasses from resting on the user's nose. When the temple bar passes through the temple bar receiver 524, the legs act the same as the cam lobe. However, when the temple bar passes through the hole diameter 522, the valve stem can operate like the cam lobe. In other cases, when the user wears glasses, the cam lobe presses against one side of the user's face, preventing the glasses from resting on the user's nose. Now refer to Figure 21 , an alternative case of a temple bar cam is shown, generally designated as 600. The temple bar cam 600 has a long, slightly curved cam lobe 620. The temple bar receiver 624 extends from the front face 650 to the back face of the temple bar cam 600. The side face 656 surrounds the perimeter (not shown) of the temple bar cam 600 located between the front face 650 and the back face.

[0067] Now refer to Figure 22 , the temple bar cam 600 is used to insert a temple bar of a pair of glasses 110 into the temple bar receiver 624. In other cases, when the user wears glasses, the cam lobe 620 presses against one side of the user's face, preventing the glasses from resting on the user's nose.

[0068] Now refer to Figure 23, shows an alternative case of a temple bar cam, generally designated as 700. The temple bar cam 700 has a shoe-shaped cross-section, with two aperture diameters 722A and 722B on the cam lobe 720, forming the shoe-shaped body, and the temple bar receiver 724 is within the shoe shape. The aperture diameters 722A, 722B, and the temple bar receiver 724 extend from the front face 750 to the back face of the temple bar cam 700. The side face 756 surrounds the perimeter of the shoe shape.

[0069] Now referring to Figure 24 , the temple bar cam 700 is used by placing the temple bar of a pair of glasses 110 within the temple bar receiver 724. In other cases, when the user wears the glasses, the cam lobe 720 presses against one side of the user's face, preventing the glasses from resting on the user's nose.

[0070] The embodiments of the present invention have been described above in conjunction with the accompanying drawings and examples. The structures given in the examples do not constitute limitations on the present invention. Those skilled in the art can make adjustments as needed, and various deformations or modifications within the scope of the appended claims are within the scope of protection.
