Description

This invention relates to eyeglasses, and in particular to eyeglasses that do not use a screw combination.

Glasses are a commonly used tool by modern humans, and whether they are used to adjust the focus of the eyes or as jewelry, they are an indispensable item for many people.

In conventional eyeglasses, screw connections or welding are used to join the temples and lens frames. However, screw connections have problems in that the assembly is cumbersome and the screws are prone to rust or fall off. On the other hand, welding has problems in that it is prone to cracking and is not environmentally friendly.

As a prior art for solving the above-mentioned problems, Taiwan Utility Model Publication No. M308418 discloses eyeglasses in which slits are provided on both sides of the lens frame, and both side walls of the connecting member pass through the slits, thereby connecting the temples and the side walls with pins. By using this arrangement method, the objective of assembling the eyeglasses is achieved without using screws. However, this pin connection method has the problem that the connecting member and the temples are easily moved relative to each other, so the eyeglasses need to be adjusted frequently.

In order to solve the above-mentioned problems, the present invention aims to provide screwless eyeglasses and temple members thereof, in which temple members are formed using a first connecting member and a second connecting member that can be engaged with each other, and the two connecting members can be connected to both sides of the lens frame by utilizing the elasticity of the material.

To achieve the above-mentioned object, the present invention provides a temple member for screwless eyeglasses that is connected to a lens frame body. The temple member for screwless eyeglasses according to the present invention includes a first connecting member and a second connecting member. The first connecting member includes a lever portion and a locking portion extending from the lever portion in a direction away from the lens frame body. The second connecting member includes an elastic portion and an engaging portion extending from the elastic portion in a direction away from the lens frame body. The locking portion is removably locked to the engaging portion. The elastic portion elastically leans on the lever portion with the engaging portion as a fulcrum. As a result, the temple end of the lens frame body is rotatably held between the elastic portion and the lever portion.

To achieve the above-mentioned object, the present invention provides screwless eyeglasses including a lens frame body and two temple members. The lens frame body includes a rim and a pair of end pieces extending from both sides of the rim. The two temple members are respectively connected to end pieces on both sides of the lens frame body. Each temple member includes a first connecting member and a second connecting member. The first connecting member includes a lever portion and a locking portion extending from the lever portion in a direction away from the lens frame body. The second connecting member includes an elastic portion and an engaging portion extending from the elastic portion in a direction away from the lens frame body. The locking portion is removably engaged with the engaging portion. The elastic portion elastically leans on the lever portion with the engaging portion as a fulcrum. As a result, the end piece is rotatably sandwiched between the elastic portion and the lever portion.

The present invention has at least the following advantages:
1. Limiting movement between the first and second connecting members by utilizing a first and second locking arrangement.
2. By utilizing the hook and stem installation, the temple member and the lens frame body are connected, and the first connecting member and the second connecting member are more tightly engaged with each other.
3. By utilizing the provision of a convex apex, the screwless eyeglasses can be easily put into use or stored state, reducing crushing of the temple members and reducing the feeling of pressure on the wearer.
4. By utilizing the fastener and groove arrangement, it is possible to securely attach the lens to the rim without the need for screws.

In order to better understand the features and technical content of the present invention, the present invention will be described in detail below with reference to the drawings. However, the drawings are used for reference and explanation only and are not intended to limit the present invention.

Figure 1 is a diagram showing the assembly of the screwless glasses according to the present invention. As shown in Figure 1, the screwless glasses 1 according to the present invention are worn on the head of a user. The screwless glasses 1 include a lens frame body 10 and a pair of temple members 20. The lens frame body 10 is placed approximately on the eye of the user. One end of the pair of temple members 20 is respectively hung on the ear of the user. The temple members 20 are installed on both sides of the lens frame body 10 by utilizing their special structure, so that they can replace the conventional fixing method of locking using screws, and there is no need to use solder for welding, so that the purpose of being environmentally friendly and easy to assemble can be achieved.

Figure 2 is a diagram showing the combination of parts of the screwless eyeglasses according to the present invention. As shown in Figure 2, one end of the temple member 20 is rotatably connected to both sides of the lens frame body 10, so that the screwless eyeglasses 1 can have a stored state and a use state. The stored state refers to the lens frame body 10 and the temple member 20 being folded against each other so as to reduce the storage space of the screwless eyeglasses 1 and reduce the probability that the user will accidentally press the temple member 20. The use state refers to the lens frame body 10 and the temple member 20 being positioned at the user's eye and auricle, respectively.

The lens frame body 10 includes a rim 11 and a pair of end pieces 12. The pair of end pieces 12 extend from either side of the rim 11 and are generally perpendicular to the rim 11. The rim 11 may have a lens (not shown) attached thereto, or may not have a lens attached thereto so that the screwless eyeglasses 1 according to the present invention can be used as jewelry.

Figure 3 is an exploded view of a portion of the screwless eyeglasses according to the present invention. The endpiece 12 is provided with a drilled hole 121, a shaft 122, and a pair of convex portions 123 located at the free end. The shaft 122 is located at one end of the endpiece 12 closer to the temple member 20, and is formed by forming the drilled hole 121. In other words, the shaft 122 is provided near the position of the drilled hole 121, and is located between the drilled hole 121 and the pair of convex portions 123. The pair of convex portions 123 extend from both ends of the shaft 122 toward the temple member 20.

The temple member 20 includes a first connecting member 21 and a second connecting member 22. The first connecting member 21 is located between the user's cheek and the second connecting member 22. In this embodiment, the first connecting member 21 and the second connecting member 22 are both made by pressing elastic metal pieces into a single piece, and the plate-like direction of the first connecting member 21 is approximately perpendicular to the user's cheek, and the plate-like direction of the second connecting member 22 is approximately parallel to the user's cheek.

The first connecting member 21 includes a lever portion 211 and a locking portion 212. The locking portion 212 is formed by extending from the lever portion 211 in a direction away from the lens frame body 10. One end of the lever portion 211 closer to the lens frame body 10 is curved and formed by extending as a hook 2111. This hook 2111 is curved toward the second connecting member 22. The width of the locking portion 212 is greater than the width of the lever portion 211. A first locking portion 2121 is provided at one end of the locking portion 212 away from the lever portion 211, and a second locking portion 2122 is provided at one end of the locking portion 212 closer to the lever portion 211.

In this embodiment, the first locking portion 2121 includes an abutment protrusion 2123 extending in a direction away from the lens frame body 10 and an accommodation groove 2124. The abutment protrusion 2123 is located on one side of the locking portion 212, and the width of the abutment protrusion 2123 is smaller than the overall width of the locking portion 212. The accommodation groove 2124 is formed by the formation of the abutment protrusion 2123, and the width of the accommodation groove 2124 is approximately equal to the thickness of the second connecting member 22.

The second locking portion 2122 includes an extension portion 2125, a fixed convex portion 2126, and a position limiting groove 2127. The extension portion 2125 is a portion that connects to the lever portion 211 of the locking portion 212. Therefore, the width of the extension portion 2125 is approximately equal to the width of the lever portion 211, and the extension portion 2125 is located on the same side as the abutting convex portion 2123. The fixed convex portion 2126 is located on the side opposite to the extension portion 2125, and extends toward the lever portion 211. The position limiting groove 2127 is located between the extension portion 2125 and the fixed convex portion 2126. Since the sum of the widths of the extension portion 2125 and the fixed convex portion 2126 is still smaller than the overall width of the locking portion 212, the position limiting groove 2127 is formed between the extension portion 2125 and the fixed convex portion 2126. The width of the position limiting groove 2127 is approximately equal to the thickness of the second connecting member 22. In this embodiment, the position limiting groove 2127 faces the endpiece 12 of the lens frame body 10.

The second connecting member 22 includes an elastic portion 221 and an engaging portion 222. The engaging portion 222 is formed by extending from the elastic portion 221 in a direction away from the lens frame body 10. An assembly slot 2211 is provided in the elastic portion 221. The length of the assembly slot 2211 is approximately equal to the length of the lever portion 211, and the width of the assembly slot 2211 is approximately equal to the thickness of the first connecting member 21. An engagement slot 2221 is provided in the engaging portion 222. The width of the engagement slot 2221 is approximately equal to the thickness of the first connecting member 21. An engagement tenon 2222 is formed between the wall surface of the engagement slot 2221 and the wall surface of the assembly slot 2211. In this embodiment, the second connecting member 22 further includes a leg 223. The leg 223 is formed by extending from the engaging portion 222 in a direction away from the lens frame body 10.

Figure 4 is an exploded view of a portion of the screwless eyeglasses 1 according to the present invention. In another embodiment of the present invention, the first connecting member 21 further includes an end piece 213. The end piece 213 is formed to extend from the locking portion 212 in a direction away from the lens frame body 10.

5 is a diagram showing the handling of the screwless eyeglasses 1 according to the present invention. As shown in FIGS. 2, 3 and 5, the longitudinal direction of the temple member 20 in the unfolded state is defined as the X-axis, and the direction perpendicular to the X-axis and parallel to the rim 11 is defined as the Y-axis. The locking portion 212 passes through the locking slot 2221, and the first locking portion 2121 and the second locking portion 2122 respectively lock onto both ends of the locking portion 222. The edge of the locking portion 222 that is away from the lens frame body 10 is accommodated in the accommodation groove 2124 of the first connecting member 21. That is, the abutment protrusion 2123 abuts against the edge of the locking portion 222 that is away from the lens frame body 10, thereby restricting the movement along the Y-axis direction between the first connecting member 21 and the second connecting member 22. The slot wall at one end of the engagement slot 2221 away from the lens frame body 10 and the groove wall at one end of the accommodation groove 2124 closer to the lens frame body 10 come into contact with each other, thereby restricting the movement along the X-axis direction between the first connection member 21 and the second connection member 22. The edge of the engagement portion 222 closer to the lens frame body 10 (i.e., the engagement tenon 2222) is accommodated in the position limiting groove 2127, and the extension portion 2125 and the fixing convex portion 2126 are provided on both sides of the edge of the engagement portion 222 closer to the lens frame body 10. As a result, the slot wall at one end of the engagement slot 2221 closer to the lens frame body 10 and the groove wall at one end of the position limiting groove 2127 closer to the lens frame body 10 come into contact with each other. That is, the engagement tenon 2222 is accommodated in the position limiting groove 2127, thereby restricting the movement along the X-axis direction between the first connection member 21 and the second connection member 22. The extension portion 2125 and the fixing protrusion portion 2126 limit the movement along the Y-axis direction between the first connection member 21 and the second connection member 22.

In this embodiment, the length of the locking portion 212 is greater than the length of the engagement slot 2221, and when the first connecting member 21 and the second connecting member 22 are attached, the lever portion 211 first penetrates the assembly slot 2211, so that the edge of the engagement portion 222 closer to the lens frame body 10 is smoothly accommodated in the position limiting groove 2127, and the abutment protrusion 2123 abuts against the other edge of the engagement portion 222.

2, 3 and 5, the hook 2111 of the lever portion 211 passes through the drilled hole 121 and is attached to the shaft portion 122, and the shaft portion 122 is provided between the hook 2111 and the elastic portion 221. That is, the convex apex 123 is provided on both sides of the lever portion 211 and abuts against the elastic portion 221. When the shaft portion 122 is engaged within the hook 2111, the shaft portion 122 pushes open the lever portion 211 and the elastic portion 221, whereby the engaging portion 222 abuts against the fixed convex portion 2126, and the elastic portion 221 moves away from the lever portion 211 with the engaging portion 222 as a fulcrum, and the lever portion 211 moves away from the elastic portion 221 with the engaging portion 222 as a fulcrum. Since the first connecting member 21 and the second connecting member 22 are both made of an elastic material, when the shaft portion 122 is engaged in the hook 2111, a force is generated in the lever portion 211 and the elastic portion 221 that tends to lean against each other, thereby firmly holding the shaft portion 122 therebetween. Because of this structural arrangement, the temple member 20 has a force that tends to move, so the screwless eyeglasses 1 according to the present invention do not limit the size of the user's head shape.

Figure 6 is an exploded view of a portion of another embodiment of the screwless eyeglasses according to the present invention. Figure 7 is a diagram showing how to handle another embodiment of the screwless eyeglasses according to the present invention. As shown in Figures 6 and 7, in another embodiment of the present invention, an abutment slat 2112 is formed by extending from one end of the lever part 211 near the lens frame body 10, and the abutment slat 2112 and the hook 2111 are parallel to each other. When the shaft part 122 is engaged in the hook 2111, the abutment slat 2112 penetrates the assembly slot 2211 and abuts a part of the abutment against the shaft part 122, thereby restricting the displacement between the first connecting member 21 and the endpiece 12. The shaft part 122 may be a circular shaft (not shown) so that the hook 2111 can rotate more smoothly when rotating around the shaft part 122.

As shown in FIG. 6, in another embodiment of the present invention, the second locking portion 2122 is provided with a notch 2128. The edge of the engagement portion 222 closer to the lens frame body 10 is accommodated in the notch 2128. In other words, the engagement tenon 2222 is accommodated in the notch 2128.

2 and 3, when the screwless eyeglasses 1 are in use, the endpiece 12 is attached to the second connecting member 22. That is, the angle between the endpiece 12 and the second connecting member 22 is 0 degrees. As described above, the shaft portion 122 pushes the lever portion 211 and the elastic portion 221 apart by a certain distance, and in this use state, the above-mentioned distance is approximately equal to the thickness of the endpiece 12. When the screwless eyeglasses 1 are in a stored state, the endpiece 12 and the second connecting member 22 form a certain angle therebetween, and this certain angle is greater than 90 degrees. Furthermore, the convex apex portion 123 presses against the second connecting member 22, so that the distance between the lever portion 211 and the elastic portion 221 becomes even greater. When the screwless eyeglasses 1 are folded from the use state to the storage state, the angle between the endpiece 12 and the second connecting member 22 becomes the above-mentioned predetermined angle from 0 degrees, the contact area and the frictional force between the convex apex 123 and the second connecting member 22 are different, and the force applied to the endpiece 12 from the lever part 211 and the elastic part 221 becomes large. As a result, the convex apex 123 is kept in a non-sliding state when the screwless eyeglasses 1 are in the use state and storage state described above. If the screwless eyeglasses 1 are not in the use state and storage state described above, the convex apex 123 slides between the second connecting member 22, and the screwless eyeglasses 1 change to the storage state or use state. This structural arrangement can replace the elastic function of the conventional spring, reduce the feeling of pressure on the wearer, and allow the user to store the screwless eyeglasses 1 more easily, and prevent the temple member 20 from being crushed due to not being completely folded.

Figure 8 shows a combination of another embodiment of screwless glasses according to the present invention. As shown in Figures 6, 7 and 8, when the screwless glasses 1 are in use, the abutment slat 2112 abuts against one end of the elastic part 221 closer to the lens frame body 10, and the notch 2128 accommodates the engagement tenon 2222 of the engagement part 222. Therefore, the notch 2128 limits the movement in the X-axis direction between the first connection member 21 and the second connection member 22. On the other hand, the abutment slat 2112 limits the movement in the Y-axis direction between the first connection member 21 and the endpiece 12.

Figures 9A and 10A are front views of another embodiment of the rim 11. Figures 9B and 10B are side views of another embodiment of the rim 11. As shown in Figure 10A, the screwless eyeglasses 1 according to the present invention further include a fixing member 30. Both ends of the fixing member 30 are abutment parts 31, and between the two abutment parts 31 is a fixing body 32. In the embodiment of the present invention, the fixing body 32 is a spring, but may also be an elastic body.

As shown in Figures 9A and 9B, the first rim 111 and the second rim 112 of the rim 11 are provided with slots 1112 and 1122, respectively. The slots 1112 and 1122 are both inclined, and incline from the inside to the outside of the rim 11 toward the connection point of the first rim 111 and the second rim 112. In other words, the slots 1112 and 1122 are closer to each other as they go from the inside to the outside.

10A and 10B, the fixing member 30 penetrates the slots 1112 and 1122, respectively, and the abutment stop parts 31 at both ends of the fixing member 30 abut against the first rim 111 and the second rim 112, respectively, so that the fixing body 32 is stretched and an elastic force is generated, and the first rim 111 and the second rim 112 are fixed using the elastic force of the fixing body 32, and the first rim 111 and the second rim 112 are elastically connected to each other. Furthermore, the oblique arrangement of the slots 1112 and 1122 makes it difficult for the fixing member 30 to slip out of the slots 1112 and 1122. When the lens is attached to the rim 11, the lens is fixed in the rim 11 by the elastic force generated by the fixing body 32 being stretched. This mounting method reduces the pressure on the lens when fixed, and therefore increases the service life of the lens. By utilizing such a structural arrangement, the lens (not shown) can be securely mounted within the rim 11 and it is possible to avoid using screws to lock the lens to the rim 11.

Thus, the present invention has at least the following advantages:
1. Limiting movement between the first and second connecting members by utilizing a first and second locking arrangement.
2. By utilizing the hook and stem installation, the temple member and the lens frame body are connected, and the first connecting member and the second connecting member are more tightly engaged with each other.
3. By utilizing the provision of a convex apex, the screwless eyeglasses can be easily put into use or stored state, reducing crushing of the temple members and reducing the feeling of pressure on the wearer.
4. By utilizing the fastener and groove arrangement, it is possible to securely attach the lens to the rim without the need for screws.

The above description is merely a preferred embodiment of the present invention and does not limit the scope of the rights of this application. Therefore, all equivalent modifications made by applying the contents of the specification and drawings of this application are included in the scope of protection of the rights of this application for the same reasons.
