Description

Temple rod cam for eyeglass support

technical field

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

Background technique

Devices to assist vision have been used since ancient times. In the second century AD Ptolemy wrote a treatise on optics that included a description of reflection and refraction. Despite the loss of classical knowledge, some progress was made in optical science in medieval Europe. The translation of Arabic writings further improved the art, and by the late Middle Ages, spectacles had appeared in Europe.

By the 18th century or so, glasses began to have what they are today, especially the cams that helped support the glasses on the wearer's face. Modern eyewear benefits from advances in material science, resulting in lightweight frames and lenses. Still, glasses add at least a few ounces of weight to the nose, and regular eyeglass wearers occasionally complain that wearing glasses can cause nose discomfort, redness, or depression. Therefore, there remains a need for a device that allows the use of conventional eyewear without the discomfort associated with contact with the wearer's nose.

SUMMARY OF THE INVENTION

In order to solve the existing problems, the present invention aims to provide a temple rod cam for supporting glasses.

In order to achieve the above purpose, in the technical scheme adopted in the present invention, the temple rods are respectively arranged on the left and right sides of the glasses, and the temple rod cam is provided with a temple rod receiver for the temple rod to pass through; A cam flap is formed after being squeezed against one side of the face; the temple bar cam is supported by the user's face and holds up the glasses.

1 . The temple rod cam for supporting glasses according to claim 1 , wherein a central portion of the temple rod cam is provided with a penetrating conical hole. 2 . The conical bore has a conical funnel shape similar to the shape of the temple bar cam body in order to maintain relatively uniform deformability over the entire length of the temple bar cam.

Among them, the temple rod cam has a conical shape.

Therein, the cam lobes 320 of the temple bar cam against the face are hook or beak-shaped, which shape provides a concave surface. provides a similar conical bore 122 to the temple rod cam

Among them, the cam lobe of the temple rod cam protrudes from the temple rod receiver in a C-shaped shape. The concave inner face of the C-shaped cam lobe 420 provides a degree of flexibility.

Among them, the temple rod cam is L-shaped, and "L" is composed of vertical line segments and horizontal line segments.

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

Among them, the temple rod cam is a shoe-shaped section, the cam flap has two apertures, and the temple rod receiver is in the shoe shape. The aperture and temple bar receiver extend from the front to the reverse of the temple bar cam.

In contrast to the prior art, the present invention, when used in pairs, is used to support a pair of eyeglasses so that the nasal septum of the eyeglasses remains above the wearer's nose. Each pair of glasses has a temple rod cam on the temple rod; when the glasses are put on the wearer's face, the temple rod cam rotates to the wearer's temple, stopping the glasses from moving down and holding the glasses in place the position above the nose;

For the wearer's comfort, the temple bar cam can be made of soft, elastic and non-toxic materials, such as medical silicone;

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

Detailed ways

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

Referring first to Figure 1, a pair of temple bar cams 100 is shown in use. A wearer (user) 102 of glasses is wearing glasses 110 . Although the glasses 110 are shown to demonstrate the operation of the temple bar cam 100, the glasses 110 are representative and the temple bar cams may be used with other glasses of similar construction, such as 3D glasses, goggles, color correction glasses, flat glasses and other similar instruments. The glasses 110 include a nose piece 112 , which is generally supported by the nose of the user 102 , so that the majority of the weight of the glasses 110 rests on the nose 104 of the user 102 . However, the left temple bar 114 and the right temple bar 116 each have a temple bar cam 110 attached. Each temple bar cam 100 is supported by the face of the user 102 , holding up the glasses 110 so that no weight is added to the nose 104 . Since a pair of glasses has two temple rods, two suns

It is normal to use one temple bar with one cam when using 100 cams at the same time.

In the preferred case, the temple bar cam 100 is made of silicone rubber with high elasticity so that the temple bar cam 100 can deform 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, so that the skin of the user 102 contacting the temple rod cam 100 will not cause discomfort or adverse reactions during use.

Referring now to FIG. 2, a temple rod 100 is described in use. The temple bar cam 100 is attached to the temple bar 114 on the left side of the glasses 110 (shown in FIG. 1 ). Broadly speaking, the temple rod cam 100 is a deformable body having a temple rod receiver 124 sized to receive the temple rod 114 of a pair of eyeglasses 110 . As the left temple rod 114 passes through the temple rod receiver 124, the body deforms to form cam lobes 142 and 144 adjacent the temple rod receiver 124 (as shown in FIG. 4). The temple bar cam 100 on the right temple bar 116, along the right side of the user's 102 face, serves a similar function and is not described separately. Once so deformed, the rest of the body assumes the shape of the cam lobe 120 relative to the temple rod receiver 124 .

When the glasses 110 are placed on the user's face, because the glasses 110 are attached to the user's ears and lower relative to the user's nose, the temple bar cam 100 slightly above the nose 104 is rotated and deformed in the direction 118 . Rotation of the glasses 110 toward the user's nose causes the cam flaps 120 of the temple bar cam 100 to contact one side of the user's face and compress in the rotational direction 118 until the temple bar cam 100 secures the glasses 110 on the user's temple. The tapered 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 rest comfortably between the left temple bar 114 and the user's 102 face.

Referring to Figure 3, the temple bar 114 on the left and the face of the user 102 are continuously creating pressure on the temple bar cam 100, which is held in place, in turn holding the glasses 110 on the nose 104 of the user 102, As shown by arrow 130 . This creates a small gap 132 between the nose piece 112 and the nose 104 of the user 102 . Therefore, the nose piece 112 does not put pressure on the nose 104 of the user 102, nor does it cause irritation, redness or depression on the nose.

4, when wearing 110 pairs of glasses, between the left temple bar 114 and the face of the user 102, where the cam lobe 120 is drawn, the temple bar cam 100 moves in the direction indicated by the arrow 140. Thus, the glasses 110 are fixed where they should be. Also visible in FIG. 4 are cam lobes 142 and 144 , which consist of partial projections of temple stem cam 100 . When the temple rod passes the temple rod receiver 124, cam lobes 142 and 144 are created.

Now as shown in FIG. 5A, when a temple rod, such as the left temple rod 114, passes through the temple rod receiver 124, the temple rod cam 100 assumes a circular appearance with a cross-sectional shape where the temple rod 114 passes through. has a tail. 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 action of the cam lobes 120 to stop the downward movement of a pair of 110 glasses (shown in FIG. 1 ).

As shown in FIG. 5B , once the glasses 110 ( FIG. 1 ) are placed on the face of the user 102 and the glasses 110 begin to be lowered to their resting position, the cam lobes 120 contacting the user's temples 102 and temple bars cause the cam lobes 120 Toward the face, rotate the deformation inward. The resiliency of the temple bar cam 100 facilitates the internal rotational movement, which allows it to deform in shape as the temple bar 114 continues to move downward.

As shown in FIG. 5C , due to the deformation of the temple bar cam shape, the temple bar 114 is ultimately positioned on one side of the cam lobe 120 , opposite the face of the user 102 . The shape of the cam lobe 120 is deformed from the original circular shape, which is realized by the elasticity of the temple rod cam 100 and the existence of the conical hole 122 to avoid discomfort to the user 102 . At this point, the rotational movement and deformation of the cam lobe 120 is stopped, and the temple rod 114 does not continue to move downward, but is held in place by the temple rod cam 100 .

Now as shown in Figure 6, where the upper base or "top" 150 (shown in Figure 8) is smaller in diameter than the lower base or "bottom" 152 (shown in Figure 7), the preferred case for the temple bar cam 100 has a taper Funnel shape, and a circular section instead of a temple pole. 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 tapered bore 122 and temple rod receiver 124 extend from the top 150 to the bottom 152 and, in some cases, form part of the injection molding process for the manufacture of the temple rod cam 100, while in other cases, at the beginning of the conical funnel shape After production, they are cut into 100 temple rod cams.

In addition to the tapered bore 122 and the temple rod receiver 124 , in the preferred case, the aperture 154 extends from the side surface 156 to the temple rod receiver 124 . In a preferred case, aperture 154 has a rectangular shape, but other shapes may be used without departing from the invention. The presence of aperture 154 creates two strips 154A and 154B (shown in Figure 11) that are elastic and can be placed on the temple rod. The aperture described allows easier entry of the temple rod into the temple rod receiver 124 of the temple cam 100 .

Referring now to FIG. 7 , a bottom view of the temple rod cam 100 of FIG. 6 is illustrated, showing the base 152 , the conical bore 122 and the temple rod receiver 124 . As shown in FIG. 7 , the conical bore 122 is also conical in the preferred case with the narrow end at the top 150 of the temple bar cam 100 (as shown in FIG. 8 ) and the 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 sides 156 from the bottom 152 to the top 150 . The conical bore 122 is not visible from this angle, but is shown in dashed lines, and the temple bar cam 100 can also be seen to gradually change from the bottom 152 to the top 150, however in the preferred case the temple bar receiver 124 maintains its The diameter does not change.

To use temple bar cam 100, one temple bar of eyeglasses 110 (shown in FIG. 1) is passed through temple bar receiver 124, into bottom 152, and out top 150, so that when eyeglasses 110 are worn, bottom 152 is facing The front of the face of the user 102 (FIG. 1).

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

Pushed outward as it passes the temple rod receiver 124 .

Referring now to FIG. 10, a rear view of the temple rod 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 (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 top perspective view of the temple bar cam 100 of FIG. 6 is shown. Here, the frustoconical shape of the temple rod cam 100 can be clearly seen, while the frustoconical shape of the conical bore 122 is shown in dashed lines. On the other hand, the shape of the temple rod receiver 124 is cylindrical. More specifically, in the preferred case, the temple bar receiver 124 is a slanted 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 Figure 11, showing the upper opening of the conical bore 122 and the temple rod receiver 124, which are approximately the same size.

Referring now to FIG. 12, a lower rear view of the temple rod cam 100 of FIG. 6 is shown. Bottom 152 is visible as tapered hole 122 under hole and temple rod receiver 124 . As can be seen in the figure, the lower hole of the conical hole 122 is significantly larger than the lower hole of the temple rod receiver 124 due to its frustoconical shape.

Referring now to Figures 13 to 24, alternative examples of temple bar cams have different shapes, resulting in varying degrees of deformability and degree of deformation of the temple bar cams. Both the deformation properties and the shape itself cause the temple bar cam to rest against the user's face in different ways. Therefore, certain users may prefer certain cases over others.

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

Referring now to FIG. 14 , the temple bar cam 200 is the temple bar 110 on which a pair of glasses is placed through the temple bar receiver 224 . In other cases, when the user wears the glasses, the cam flap 220 (shown in FIG. 13 ) presses against the side of the user's face, preventing the glasses from resting on the user's nose.

Referring now to Figure 15, an alternate example of a temple bar cam, usually designated 300, is shown. The cam lobe 320 of the temple rod 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 conical hole 122 to the temple rod cam 200 (eg. 2), and the cylindrical bore 222 provides flexibility to the temple bar cam 200 (FIG. 13). The temple bar receiver 324 is located at the beak-shaped projection from the cam lobe 320 and, as in the other cases, is a hole extending from the top surface 350 of the temple bar cam 300 to the bottom surface (not shown). 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 glasses, the cam flap 320 is pressed against the side of the user's face, preventing the glasses from resting on the user's nose.

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

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

Referring now to Figure 19, an alternate example of a temple bar cam, usually designated 500, is shown. Temple bar cam 500 is L-shaped. The letter "L" is composed of a vertical line (or "stem") and a horizontal line (or

"legs") are formed perpendicular to the stem and extend to the right from the bottom end of the stem. The legs are almost always shorter than the valve stem, and the corresponding parts of the temple bar cam 500 are no exception. In Figure 19, the temple stem cam 500 is shown level with the valve stem as if the "L" was rotated 90° clockwise. The ends of the stem, the ends of the legs, and the intersection of the stem and the legs are all rounded. There is a concave edge between the intersection of the legs and the end. The hole 522 is located at the end of the valve stem and the temple rod receiver 524 is located at the end of the leg. Both the hole 522 and the temple rod receiver 524 extend from the front side 550 to the reverse side of the temple rod cam 500 . Side 556 extends along the perimeter of the L-shape.

In temple rod cam 500, aperture 522 is shaped like temple rod receiver 524, which allows some flexibility for the user because the roles of aperture 522 and temple rod receiver 524 can be interchanged. More specifically, depending on the user's preference, the user may choose to place a temple rod in the aperture 522, rather than a temple rod in the temple rod receiver 524, for the user when using the temple rod cam 500. bring different feelings.

Referring now to FIG. 20 , temple bar cam 500 is a temple bar that fits a pair of glasses 110 at temple bar receiver 524 . Alternatively, the temple rod may pass through aperture 522. In other cases, when the user wears the glasses, the cam flaps press against the side of the user's face, preventing the glasses from resting on the user's nose. When the temple rod passes through the temple rod receiver 524, the legs function like cam lobes. However, when the temple rod passes through aperture 522, the valve rod can function as a cam flap. In other cases, when the user wears the glasses, the cam flaps press against the side of the user's face, preventing the glasses from resting on the user's nose.

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

Referring now to FIG. 22 , the temple bar cam 600 is used to receive the temple bar of a pair of glasses 110 at the temple bar receiver 624 . In other cases, when the user wears the glasses, the cam flap 620 is pressed against one side of the user's face, preventing the glasses from resting on the user's nose.

Referring now to Figure 23, an alternate example of a temple rod cam, usually designated 700, is shown. Temple rod cam 700 has a shoe-shaped cross-section with two apertures 722A and 722B in cam lobe 720, forming the body of the shoe, with temple rod receiver 724 in the shoe. The apertures 722A, 722B and temple rod receiver 724 extend from the front face 750 to the reverse face of the temple rod cam 700 . Sides 756 enclose the perimeter of the shoe shape.

Referring now to FIG. 24 , the temple bar cam 700 is used by placing the temple bar of a pair of glasses 110 in the temple bar receiver 724 . In other cases, when the user wears the glasses, the cam flap 720 is pressed against the side of the user's face, preventing the glasses from resting on the user's nose.
