Technical Field

The present invention relates to a support device for use with eyeglasses, and more particularly, to a cam for securing eyeglasses to reduce the weight of the eyeglasses and to avoid over-squeezing the nose.

Background

Devices for assisting vision have been used since ancient times. An optical monograph was written in the second century, tollemi (Ptolemy), which includes descriptions of reflection and refraction. Although classical knowledge has been lost, there have been some advances in optical science in europe of the middle ages. Translation of the arabic work further improved the artistic level, and by the late middle century, glasses have emerged in europe.

By around the 18 th century, eyeglasses began to have their appearance today, particularly the cams that help support the eyeglasses on the face of the wearer. Modern eyeglasses benefit from advances in material science, resulting in lightweight frames and lenses. Despite this, spectacles add at least a few ounces to the nose and even people who often wear spectacles complain that wearing spectacles results in nasal discomfort, redness or depression. Thus, there remains a need for a device that can be used with conventional eyeglasses without the discomfort of contacting the wearer's nose.

Disclosure of Invention

The invention aims to solve the existing problems and provides a temple bar cam for a spectacle support.

In order to achieve the purpose, the invention adopts the technical scheme that the glasses are respectively arranged on temple bars at the left side and the right side of the glasses, and a temple bar receiver for the temple bars to pass through is arranged on a temple bar cam; the temple bar cam is extruded to form a cam lobe after being attached to one side of the face; the temple bar cam is supported by the user's face and holds the eyeglasses up.

1. The temple bar cam for an eyeglass support of claim 1, wherein the temple bar cam has a conical bore therethrough at a central portion thereof. The conical bore has a conical funnel shape similar to the shape of the body of the temple bar cam so as to maintain relatively uniform deformability throughout the length of the temple bar cam.

Wherein, the temple bar cam is in a conical shape.

Wherein the temple bar cam face-engaging cam lobe 320 is hook or beak shaped, which provides a concave surface. A cam similar to the conical bore 122 is provided for the temple bar

Wherein the cam lobes of the temple bar cam extend from the temple bar receiver in a C-shaped configuration. The concave inner face of the C-shaped cam lobe 420 provides a degree of flexibility.

The temple bar cam is L-shaped, and the "L" is composed of a vertical line segment and a horizontal line segment.

Wherein, the cam lobe of the temple bar cam has a strip shape with slight bending.

Wherein, the temple bar cam is a shoe-shaped cross section, the cam lobe has two apertures, and the temple bar receiver is in the shoe shape. The aperture and temple bar receiver extend from the front face to the back face of the temple bar cam.

In contrast to the prior art, the present invention is used to support a pair of eyeglasses when in use, such that the nasal septum of the eyeglasses remains over the nose of the wearer. A temple bar cam is arranged on the temple bar of each pair of glasses; when the glasses are worn on the face of a wearer, the temple bar cam can rotate to the temple of the wearer to stop the glasses from moving downwards and fix the glasses at a position above the nose of the wearer;

the temple bar cam may be made of a soft, elastic and non-toxic material, such as medical grade silicone, for wearer comfort;

the conical frustum shape of the temple bar cams further enhances comfort for the wearer, and the holes extending through each temple bar cam are to increase the deformability of the temple bar cam shape.

Detailed Description

The invention will now be further described with reference to the accompanying drawings.

Referring first to fig. 1, a pair of temple bar cams 100 are shown in use. A wearer (user) 102 of the glasses is wearing glasses 110. Although the eyeglasses 110 are shown to demonstrate the operation of the temple bar cam 100, the eyeglasses 110 are representative and the temple bar cam may be used with other similarly configured eyeglasses, such as 3D eyeglasses, goggles, color correction glasses, piano glasses, and other similar instruments. The eyeglasses 110 include a nose piece 112. the nose piece 112 is generally supported by the nose of the user 102 such that a majority of the weight of the eyeglasses 110 is pressed against the nose 104 of the user 102. However, a temple lever cam 110 is attached to each of the left temple lever 114 and the right temple lever 116. Each temple bar cam 100 is supported by the face of the user 102, holding the eyeglasses 110 up so that there is no weight gain on the nose 104. Because a pair of glasses has two temple bars, two suns

The pocket bar cam 100 is used simultaneously, and it is normal for one pocket bar to be used with one cam.

In a preferred embodiment, the temple bar cam 100 is made of silicone rubber and has a high degree of elasticity so that the temple bar cam 100 can be deformed during use as described below and return to its original shape after use. In the first case, the silicone rubber used is medical grade silicone rubber, which may not cause discomfort or adverse effects to the skin of the user 102 contacting the temple bar cam 100 during use.

Referring now to fig. 2, a temple bar 100 is depicted in use. The temple bar cam 100 is attached to a temple bar 114 (shown in fig. 1) on the left side of the eyewear 110. In a broad sense, the temple bar cam 100 is a deformable body having a temple bar receiver 124 sized to receive the temple bar 114 of a pair of eyeglasses 110. As the left temple bar 114 passes through the temple bar receiver 124, the body deforms to form cam lobes 142 and 144 (as depicted in fig. 4) adjacent the temple bar receiver 124. The temple bar cam 100 on the right temple bar 116 follows the right side of the face of the user 102 for a similar purpose and is not separately described. Once so deformed, the remainder of the body assumes the shape of the cam lobe 120 relative to the temple bar receiver 124.

When the eyeglasses 110 are placed on the user's face, the temple bar cams 100, which are slightly above the nose 104, are rotationally distorted in the direction 118 because the eyeglasses 110 are attached to the user's ears and are low relative to the user's nose. Rotation of the eyeglasses 110 toward the nose of the user causes the cam lobes 120 of the temple bar cam 100 to contact one side of the user's face and compress in the direction of rotation 118 until the temple bar cam 100 secures the eyeglasses 110 on the user's temples. The conical bore 122 in the temple bar cam 100 allows the temple bar cam 100 to be sufficiently deformed so that the temple bar cam 100 can comfortably rest intermediate the left temple bar 114 and the face of the user 102.

Referring to fig. 3, the left temple bar 114 and the face of the user 102 continue to exert pressure on the temple bar cam 100, and the temple bar cam 100 is held in place, in turn, holding the eyeglasses 110 against the nose 104 of the user 102, as indicated by arrow 130. This creates a small gap 132 between the nose piece 112 and the nose 104 of the user 102. Thus, the nose bridge 112 does not exert pressure on the nose 104 of the user 102, nor does it produce irritation, redness, or depression on the nose.

Referring to fig. 4, when the pair 110 of eyeglasses is worn, the temple bar cam 100 moves in the direction indicated by arrow 140 between the left temple bar 114 and the face of the user 102 where the cam lobes 120 are drawn. Thus, the eyeglasses 110 are fixed in the position they would otherwise be in. Also visible in fig. 4 are cam lobes 142 and 144, which are comprised of partial lobes of the temple stem cam 100. As the temple bar passes through the temple bar receiver 124, cam lobes 142 and 144 are created.

Now as shown in fig. 5A, 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 rounded appearance with a tail where the temple bar 114 passes. The tails correspond to the cam lobes 142 and 144 shown in fig. 4. The remaining circular portion of the temple bar cam 100 explains the downward movement of the pair 110 of eyeglasses (as viewed in fig. 1) as being stopped by the action of the cam lobe 120.

As shown in fig. 5B, once the eyeglasses 110 (fig. 1) are placed on the face of the user 102 and the eyeglasses 110 begin to lower to their resting position, the cam lobes 120 contacting the user's temples 102 and temples bars rotationally deform the cam lobes 120 inwardly toward the face. The resiliency of the temple bar cam 100 facilitates the inward rotational movement, which allows it to deform in shape as the temple bar 114 continues to move downward.

As shown in fig. 5C, the temple bar 114 is ultimately positioned on one side of the cam lobe 120, opposite the face of the user 102, due to the deformation of the temple bar cam shape. The shape of the cam lobe 120 is deformed from its original circular shape by the resiliency of the temple bar cam 100 and the presence of the conical bore 122 to avoid discomfort to the user 102. At this point, the rotational movement and deformation of the cam lobe 120 ceases and the temple bar 114 no longer continues to move downward, but it is held in place by the temple bar cam 100.

Referring now to fig. 6, in the upper portion or "top" 150 of the base (as shown in fig. 8) having a smaller diameter than the lower portion or "bottom" 152 of the base (as shown in fig. 7), the preferred embodiment of the temple bar cam 100 has a tapered funnel shape and a circular cross-section rather than a temple bar. This conical funnel shape ensures contact between the temple bar cam 100 and the user's 102 temple along the entire length of the temple bar cam 100. The conical bore 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 of the temple bar cam 100 fabrication, while in other cases, after the initial production of the tapered funnel shape, they are cut into the temple bar cam 100.

In addition to the tapered bore 122 and the temple bar receiver 124, in a preferred case, an 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 may be used without departing from the invention. The presence of the apertures 154 forms two strips 154A and 154B (shown in fig. 11) that are resilient and can be placed on a temple bar. The aperture allows the temple bar to more easily enter the temple bar receiver 124 of the temple cam 100.

Referring now to fig. 7, a bottom view of the temple bar cam 100 of fig. 6 is illustrated showing the bottom 152, the conical bore 122, and the temple bar receiver 124. As shown in fig. 7, the conical bore 122 is also conical in the preferred case, with a narrow end at the top 150 of the temple bar cam 100 (as shown in fig. 8) and a wide end at the bottom 152 of the temple bar cam 100.

Referring now to fig. 8, a right side view of the temple bar cam 100 of fig. 6 is illustrated showing the tapering of the side 156 from the bottom 152 to the top 150. The conical bore 122 is not visible from this perspective, but is shown in phantom, and it can also be seen that the temple bar cam 100 gradually tapers from the bottom 152 to the top 150, while in the preferred case the temple bar receiver 124 maintains its diameter throughout.

To use the temple bar cam 100, a temple bar of the eyewear 110 (shown in fig. 1) is passed through the temple bar receiver 124, into the bottom portion 152, and out the top 150, so that the bottom portion 152 faces the front of the face of the user 102 (fig. 1) when the eyewear 110 is worn.

Referring now to fig. 9, a front view of the temple bar cam 100 of fig. 6 is illustrated, showing the rectangular aperture 154. Unlike the conical bore 122 and the temple bar receiver 124 (shown in fig. 7), the aperture 154 does not extend from the bottom 152 to the top 150; rather, it is substantially centered between the bottom 152 and the top 150. This forms portions of the sides 156 (shown in FIG. 7) above and below the rectangular aperture 154 of the cam lobes 142 and 144 (shown in FIG. 4)

Pushed outward when passing through the temple bar receiver 124.

Referring now to fig. 10, a rear view of the temple lever cam 100 of fig. 6 is shown. The rectangular aperture 154 is shown in phantom because it extends only to the temple bar receiver 124 (as shown in fig. 7) and is therefore not visible from the opposite side of the temple bar cam 100.

Referring now to fig. 11, a front upper perspective view of the temple lever cam 100 of fig. 6 is shown. Here, the truncated cone shape of the temple bar cam 100 can be clearly seen, while the dashed line shows the truncated cone shape of the conical bore 122. The temple bar receiver 124, on the other hand, is cylindrical in shape. More specifically, in the preferred case, the temple bar receiver 124 is a beveled cylinder that maintains a constant distance between the center of its cross-sectional circle and the nearest edge of the side 156. The top 150 can be seen in fig. 11, showing the upper opening of the conical bore 122 and the temple bar receiver 124, which are approximately the same size.

Referring now to fig. 12, a lower rear view of the temple lever cam 100 of fig. 6 is shown. The bottom 152 is visible as the lower hole of the tapered bore 122 and the temple bar receiver 124. As can be seen from the figure, due to its truncated cone shape, the lower bore of the conical bore 122 is significantly larger than the lower bore of the temple bar receiver 124.

Referring now to fig. 13-24, alternative cases of the temple bar cam have different shapes, which differ to different degrees in the degree of easy and deformation of the shape. Both the deformation characteristics and the shape itself cause the temple bar cam to rest against the user's face in different ways. Thus, a particular user may prefer a particular case over other cases.

Referring now to fig. 13, an alternate example of a temple bar cam is shown, generally designated 200. The temple bar cam 200 has a substantially cylindrical cam lobe 220 and a cylindrical bore 222 through the center thereof. A temple bar receiver 224 with an elliptical cross-section creates a protrusion from the cylindrical shape of the cam lobe 220. The obverse side 250 of the temple bar cam 200 is substantially similar in appearance to the reverse side (not shown) thereof, with both the cylindrical aperture 222 and the temple bar receiver 224 extending from the obverse side 250 to the reverse side. The aperture 254 on the side 256 of the temple bar cam 200 is located on the projection and extends into the interior of the temple bar receiver 224.

Referring now to fig. 14, a temple bar cam 200 is a temple bar 110 for placing a pair of eyeglasses through a temple bar receiver 224. In other cases, when the user is wearing the eyeglasses, cam lobe 220 (shown in fig. 13) presses against the side of the user's face, preventing the eyeglasses from resting on the user's nose.

Referring now to fig. 15, an alternate example of a temple bar cam is shown, generally designated 300. The cam lobe 320 of the temple bar cam 300 does not have a hole through it, but the hook or beak shape of the cam lobe 320 provides a concave surface, which provides a similar flexibility to that provided by the conical bore 122 provided to the temple bar cam 200 (shown in fig. 2), and the cylindrical bore 222 provided to the temple bar cam 200 (shown in fig. 13). The temple bar receiver 324 is located at a beak projection from the cam lobe 320 and, as with the other cases, is an aperture extending from the top surface 350 to the bottom surface (not shown) of the temple bar cam 300. The temple bar cam 300 also has a side 356.

Referring now to fig. 16, the temple bar cam 300 is used by placing the temple bar of a pair of eyeglasses 110 into the temple bar receiver 324. In other cases, when the user wears the eyeglasses, cam lobe 320 presses against one side of the user's face, preventing the eyeglasses from resting on the user's nose.

Referring now to fig. 17, an alternate example of a temple bar cam is shown and is generally designated 400. In the temple bar cam 400, the cam lobe 420 extends in a C-shape from the temple bar receiver 424. The front surface 450 and the substantially similar back surface form a C-shaped cross-section surrounded by side surfaces 456. As with the other cases, the temple bar receiver 424 extends from the front side 450 through to the back side (not shown) via the temple bar cam 400. The concave inner face of the C-shaped cam lobe 420 provides a degree of flexibility for deformation of the temple bar cam 400 during use.

Referring now to fig. 18, a temple bar cam 400 is used by placing a temple bar of a pair of eyeglasses 110 into a temple bar receiver 424. In other cases, when the user wears the eyeglasses, the cam lobes 420 press against one side of the user's face, preventing the eyeglasses from resting on the user's nose.

Referring now to fig. 19, an alternate example of a temple bar cam is shown, generally designated 500, the temple bar cam 500 is L-shaped, and the letter "L" consists of a vertical line segment (or "stem") and a horizontal line segment (or "stem")

"legs") that extend perpendicularly from the valve stem to the right from the bottom end of the valve stem, the length of the legs is almost always shorter than the valve stem, and the corresponding features of the temple lever cam 500 are no exception in fig. 19, the temple lever cam 500 is shown to be horizontal with the valve stem as if it were rotated 90 clockwise.

In the temple bar cam 500, the aperture 522 is shaped similar to the temple bar receiver 524, which gives the user some flexibility in that the roles of the aperture 522 and the temple bar receiver 524 can be interchanged. More particularly, the user may choose to place a temple bar in the aperture 522, rather than a temple bar in the temple bar receiver 524, according to the user's preference, to give the user a different feel when using the temple bar cam 500.

Referring now to fig. 20, a temple bar cam 500 is a temple bar that is received into a pair of eyeglasses 110 at a temple bar receiver 524. Alternatively, a temple bar may pass through aperture 522. In other cases, the cam lobe presses against one side of the user's face when the user is wearing the eyeglasses, preventing the eyeglasses from resting on the user's nose. The legs act like cam lobes as the temple bars pass through the temple bar receiver 524. However, when the temple bar passes through the aperture 522, the valve stem can function as a cam lobe. In other cases, the cam lobe presses against one side of the user's face when the user is wearing the eyeglasses, preventing the eyeglasses from resting on the user's nose.

Referring now to fig. 21, an alternate example of a temple bar cam is shown, generally designated 600. The temple bar cam 600 has a long, slightly curved cam lobe 620. The temple bar receiver 624 extends from the front side 650 to the opposite side of the temple bar cam 600. Side 656 surrounds the perimeter (not shown) of the temple lever cam 600 between the front 650 and the back.

Referring now to fig. 22, a temple bar cam 600 is used to engage a temple bar of a pair of eyeglasses 110 at a temple bar receiver 624. In other cases, when the user wears the eyeglasses, cam lobe 620 presses against one side of the user's face, preventing the eyeglasses from resting on the user's nose.

Referring now to fig. 23, an alternate example of a temple bar cam is shown, generally designated 700. The temple bar cam 700 has a shoe-shaped cross-section with two apertures 722A and 722B in the cam lobe 720 forming the body of the shoe shape and the temple bar receiver 724 in the shoe shape. The apertures 722A, 722B and the temple bar receiver 724 extend from the front side 750 to the opposite side of the temple bar cam 700. Side 756 encompasses the perimeter of the shoe shape.

Referring now to fig. 24, a temple bar cam 700 is used by inserting a temple bar of a pair of eyeglasses 110 into a temple bar receiver 724. In other cases, when the user wears the eyeglasses, the cam lobe 720 presses against one side of the user's face, preventing the eyeglasses from resting on the user's nose.

The embodiments of the present invention have been described in conjunction with the accompanying drawings and examples, the structures of which are given by way of illustration and not limitation, and those skilled in the art can make modifications as required, and various changes and modifications can be made within the scope of the appended claims.
