Description

Mirror legs and spectacle frame devices

The present invention relates to a spectacle frame device, and in particular, to a spectacle frame device that can be worn on the head to place lenses or displays in front of the eyes and its temples.

Existing eyeglass frame devices are usually equipped with lenses or displays for use as ordinary glasses or head-mounted devices such as augmented reality (AR) glasses and virtual reality (VR) glasses. However, when the user wears the spectacle frame device, he or she will often feel uncomfortable because the size of the spectacle frame device does not fit the shape of the head, resulting in the user being unable to wear the spectacle frame device for a long time. In addition, the spectacle frame device may easily fall off. The user's head slips off.

Therefore, the object of the present invention is to provide a temple that can solve at least one of the aforementioned problems.

Therefore, the temples of the present invention include a temple body and a holder.

The holder is disposed at the rear end of the lens body and includes a flexible clamping structure extending from front to back. The clamping structure has a first side wall, a second side wall and a plurality of horizontal columns with different left and right widths. The first side wall and the second side wall are respectively located on the left and right sides of the clamping structure, and the distance between the first side wall and the second side wall tapers from front to back. Two opposite ends of the horizontal columns are connected to the first side wall and the second side wall respectively. The horizontal columns are arranged at intervals from front to back and their left and right widths decrease.

Wherein, when the side of the first side wall adjacent to the mirror body is exerted a contact force toward the second side wall, the horizontal columns will be driven to use the connections between the horizontal columns and the first side wall as fulcrums. Rotate backward so that the side of the clamping structure away from the lens body is bent in a direction opposite to the direction in which the contact force is applied.

In some embodiments, the temples further include a pivot vertically extending through the rear end of the temples body. The holder also includes a pivot member connected to the pivot shaft that can rotate left and right. The side of the pivot member away from the lens body is provided for the clamping structure. When the contact force is exerted on the side of the first side wall adjacent to the mirror body, the clamping structure will rotate with the pivot axis in the opposite direction to the direction of application of the contact force, and drive the lateral sides. The columns respectively rotate backward with the connection between the horizontal columns and the first side wall as a fulcrum, so that the side of the clamping structure away from the mirror body bends in a direction opposite to the direction of application of the contact force.

In some embodiments, each horizontal column has two joint parts respectively connected to the first side wall and the second side wall, and a support part with left and right ends respectively connected to the joint parts. The thickness of the joint portions in the extension direction of the clamping structure is smaller than the thickness of the support portion in the extension direction of the clamping structure.

In some implementations, the front side surfaces of the joint parts are flush with the front side surfaces of the support part.

In some implementations, the front side and the rear side of the joint parts are located between the front side and the rear side of the support part.

In some embodiments, the holder further includes a soft sleeve covering the clamping structure to cover the horizontal columns.

In some implementations, an included angle between the first side wall and any one of the horizontal columns is greater than an included angle between the second side wall and any one of the horizontal columns.

In some implementations, an included angle between the first side wall and any one of the horizontal columns is equal to an included angle between the second side wall and any one of the horizontal columns.

Another object of the present invention is to provide an eyeglass frame device having the aforementioned temples.

Therefore, the spectacle frame device of the present invention is suitable for being worn on a user's head. The spectacle frame device includes a spectacle frame and two aforementioned temples.

The mirror legs are respectively arranged on the left and right sides of the frame. The temple body of each temple extends backward from the frame.

Wherein, when the glasses frame device is worn on the user's head, the side of the first side wall of each temple adjacent to the corresponding temple body will be pressed by the user's head toward the corresponding third The contact force of the two side walls drives the corresponding horizontal columns to rotate toward the rear with the connection between the corresponding horizontal columns and the corresponding first side wall as a fulcrum, so that the corresponding clamper moves away from the corresponding first side wall. One side of the lens body is bent in a direction opposite to the direction of application of the contact force to fit the user's head.

The effect of the present invention is that by virtue of the characteristic that the clamping structure will bend toward the force-bearing place after being stressed, the holder can adaptively fit the contour of the user's head and correspond to different head shapes. The user adjusts the curvature of the holder to achieve good wearing comfort. In addition, due to the characteristics of the holders that will automatically bend and fit the rear edge of the user's head after being exerted by the user's head, the glasses frame device cannot slide forward. To achieve a stable wearing effect.

Referring to FIGS. 1 to 5 , an embodiment of the spectacle frame device of the present invention is shown. First, define the direction terms used in the description here. In subsequent explanations, the direction from left to right in the figure is defined as the first direction X, the direction from front to back in the figure is defined as the second direction Y, and the direction from bottom to bottom in the figure is defined as the first direction X. The upward direction is defined as the third direction Z. The spectacle frame device is suitable for mounting components not shown in the figure, such as lenses or displays, and is worn on the head of a user 9 . The spectacle frame device includes a spectacle frame 100 suitable for being placed in front of the eyes of the user 9 and extending in the first direction The temples 200 are provided on the left and right sides of the head. Subsequently, for convenience of description and to simplify the description, the temple 200 located on the left side in FIG. 1 is defined as a temple 200a, and the temple 200 located on the right side in FIG. 1 is defined as a temple 200b. Moreover, in FIG. 2 to FIG. 4 , the temple leg 200 a is used as an example. The temple leg 200 b and the temple leg 200 a are arranged left and right symmetrically in terms of structural configuration, and will not be described again here.

Referring to FIGS. 1 to 4 , each of the temple legs 200 includes a temple body 1 extending rearwardly from the frame 100 (that is, extending along the second direction Y), and an elongated temple body 1 erected through the rear end of the temple body 1 . The pivot 2, and a holder 3 provided at the rear end of the lens body 1. The lens body 1 may be rod-shaped, plate-shaped or other shapes, and is not limited to a specific shape. Furthermore, each pivot 2 extends in the third direction Z. Each holder 3 includes a pivot member 4 that can rotate left and right and is connected to the pivot shaft 2, and a pivot member 4 extending from the side of the pivot member 4 away from the lens body 1 from front to back (toward the second direction Y). ) an extending and flexible clamping structure 5, and an connecting piece 6 that can be inserted into the pivot piece 4. That is to say, each pivot member 4 can rotate toward the first direction X or in a direction opposite to the first direction X with the corresponding pivot 2 as the axis. In this embodiment, the connecting parts 6 are used to detachably fix the clamping structures 5 to the pivoting part 4 respectively, but in other embodiments, the connecting parts 6 may also be omitted. That is to say, the clamping structures 5 are connected to the pivot members 4 respectively.

Referring to Figures 1, 3 to 5, each clamping structure 5 has a first side wall 51 adjacent to the head of the user 9, a second side wall 52 away from the head of the user 9, and a plurality of The horizontal pillar 53 is located between the first side wall 51 and the second side wall 52 and has different widths in the first direction X. Specifically, the first side wall 51 and the second side wall 52 of each clamping structure 5 are respectively located on the left and right sides of the clamping structure 5 . And the first side wall 51 of each clamping structure 5 extends in the second direction Y along the extension direction of the corresponding mirror body 1 (see Figure 1), and the second side wall 51 of each clamping structure 5 The side wall 52 extends obliquely rearward from the side of the corresponding pivot member 4 away from the first side wall 51 and is connected to the first side wall 51 , so that the cross section of each clamping structure 5 appears similar to a horizontal bar in the middle. of hollow triangles. That is to say, the distance between the first side wall 51 and the second side wall 52 of each clamping structure 5 is tapered along the second direction Y.

Referring to FIGS. 4 to 6 , two opposite ends of the horizontal columns 53 of each clamping structure 5 are respectively connected to one side of the corresponding first side wall 51 and the corresponding second side wall 52 facing each other. Moreover, the horizontal columns 53 of each clamping structure 5 are arranged at intervals along the second direction Y, and the width of the horizontal columns 53 of each clamping structure 5 in the first direction X corresponds to the width of the first direction Y. The distance between the side wall 51 and the second side wall 52 gradually decreases. In this way, when the user 9 wants to wear the spectacle frame device on the head of the user 9 , the temples 200 will be respectively disposed on the left and right sides of the head of the user 9 , and each The side of the first side wall 51 of the temple 200 adjacent to the corresponding temple body 1 (ie, the position in contact with the head of the user 9 in FIG. 5 ) will be exerted by the head of the user 9 in a direction. Correspondingly, the contact force F of the second side wall 52 (shown by the arrow in Figure 5). Moreover, when the contact force F is exerted on each first side wall 51 toward the corresponding second side wall 52 , the corresponding first side wall 51 will drive the corresponding horizontal columns 53 with the horizontal columns 53 and the corresponding horizontal columns 53 respectively. The connection point of the first side wall 51 is a fulcrum for rearward rotation, and the shorter the left and right widths of the horizontal columns 53 in the first direction X, the shorter the direction toward the first direction X or opposite to the first direction X. The greater the rotation amplitude will be, this will make the corresponding clamping structure 5 move away from the corresponding side of the lens body 1 (that is, the rear end of the clamping structure 5, or the tip of the clamping structure 5 ) will bend from the transition state as shown in Figure 5 in the direction opposite to the application direction of the contact force F, and transform into the use state as shown in Figure 6, thereby allowing the holder 3 to fit the user 9 The head of the user 9 can be provided with a clamping force to clamp the head of the user 9 .

In this embodiment, the material of the clamping structures 5 can be a thermoplastic material with good ductility such as polylactic acid (Polylactic Acid or Polylactide, referred to as PLA) or polypropylene (Polypropylene, referred to as PP). The material of the structure 5 can also be a rubber material (for example: Thermoplastic Polyamide Elastomer (TPA)), nylon (Nylon) or titanium (Ti) and other ductile materials, and is not limited to the above description. . And the clamping structures 5 can be integrally formed by, for example, injection molding, which has better structural stability and reduces production costs. However, the clamping structures 5 can also be composed of multiple components. It is not limited to a specific form.

Referring to FIG. 3 and FIG. 7 , in an implementation aspect of this embodiment (see FIG. 3 ), the number of the horizontal columns 53 is nine. The greater the number of the horizontal columns 53 , the better the support of the clamping structures 5 can be. However, in another implementation aspect of this embodiment (see Figure 7), the number of the horizontal posts 53 can also be reduced relative to the aspect in Figure 3 (here are five examples), so that the clamping Structure 5 bends more easily.

Referring to Figures 3 and 4, preferably, each horizontal column 53 has two joint portions 531 that are respectively connected to the corresponding first side wall 51 and the corresponding second side wall 52 and can be bent, and a left and right joint portion 531. The two right ends are connected to the supporting parts 532 of the joint parts 531 respectively. The thickness of the joint portions 531 of each clamping structure 5 in the extension direction (the second direction Y) of the clamping structure 5 is smaller than the thickness of the support portion 532 of each clamping structure 5 in the extending direction of the clamping structure 5 . The thickness in the extension direction (ie, the second direction Y) makes it easier for the clamping structure 5 to rotate using the joint portions 531 as fulcrums. That is to say, when the contact force F is exerted on the first side wall 51 of each clamping structure 5 to drive the corresponding horizontal columns 53 to rotate rearward, the corresponding horizontal columns 53 will be adjacent to the third The joint portions 531 of the side wall 51 serve as fulcrums to rotate backward, making it easier for the corresponding clamping structure 5 to bend.

Referring to Figures 3, 4, and 9, specifically, in this embodiment, such as the implementation of Figures 3 and 4, the front and rear sides of the joint portions 531 are located on the front and rear sides of the support portion 532. Between the rear sides, in this way, a notch-like design is formed on the front and rear sides of the horizontal posts 53 (corresponding to the joint portions 531), so that the clamping structures 5 can easily rotate backward. However, in another implementation aspect of this embodiment (see Figure 9), the clamping structures 5 can also be designed so that the front side of the joint portions 531 is flush with the front side of the support portion 532, and the horizontal A notch-like design is still formed on the rear side of the column 53 (corresponding to the joint portion 531 ), which also allows the clamping structures 5 to easily rotate backward.

Referring to Figures 3, 4, and 8, preferably, in this embodiment such as the implementation of Figures 3 and 4, any one of the first side wall 51 of each clamping structure 5 and the horizontal columns 53 The angle θ1 between them is greater than the angle θ2 between the second side wall 52 and any one of the horizontal columns 53 . For example, the shape of the clamping structures 5 is similar to a right-angled triangle, and the angle θ1 between the first side wall 51 of each clamping structure 5 and any one of the horizontal columns 53 is 90 degrees, and The angle θ2 between the second side wall 52 of each clamping structure 5 and any one of the horizontal columns 53 is less than 90 degrees. In this way, the length of the second side wall 52 in the second direction Y will be greater than The length of the first side wall 51 in the second direction Y enables the clamping structure 5 to be bent only toward the outside of the first side wall 51 . However, in another implementation aspect of this embodiment (see Figure 8), each clamping structure 5 can also be designed such that the angle θ1 between the first side wall 51 and any one of the horizontal columns 53 is equal to the angle θ1. The angle θ2 between the second side wall 52 and any one of the horizontal columns 53 . That is to say, the lengths of the first side wall 51 and the second side wall 52 in the second direction Y are equal and are arranged symmetrically (the shape of the clamping structures 5 is similar to an isosceles triangle). In this way, the clamping structure The structure 5 can be bent toward the outside of the first side wall 51 or towards the outside of the second side wall 52 .

Furthermore, the clamping structure 5 is provided on the side of each pivot member 4 away from the lens body 1 . When the contact force F is applied to the side of the first side wall 51 of each clamping structure 5 adjacent to the mirror body 1, the clamping structure 5 will first take the pivot 2 as the axis toward the contact force F. Rotating in the opposite direction to the application direction of F increases the contact area between the clamping structure 5 and the head of the user 9 , thus increasing the magnitude of the contact force F. Then, the horizontal pillars 53 are affected by the increase in the contact force F and the amplitude of rotation toward the rear increases, so that the side of the clamping structure 5 away from the lens body 1 faces the direction opposite to the direction in which the contact force F is applied. The bending force increases, thereby increasing the clamping force exerted by the clamping structure 5 on the head of the user 9 .

Preferably, each holder 3 also includes a soft cover 7 . Each soft sleeve 7 can be flexibly wrapped around the corresponding clamping structure 5 to cover the corresponding horizontal columns 53 so that foreign matter cannot enter the corresponding horizontal columns 53, the corresponding first side wall 51 and the corresponding space between the second side walls 52 to avoid affecting the corresponding bending of the clamping structure 5 .

To sum up, by virtue of the characteristic that the clamping structure 5 will bend towards the force-receiving location after receiving force, the holder 3 can adaptively fit the head contour of the user 9 and correspond to different heads. The user 9 adjusts the curvature of the holder 3 to achieve good wearing comfort. In addition, due to the characteristic that the holders 3 will automatically bend and fit the rear edge of the head of the user 9 after being exerted by the head of the user 9, the spectacle frame device cannot be moved toward the head. Slide forward to achieve a stable wearing effect. , so the purpose of the present invention can indeed be achieved.

However, the above are only examples of the present invention. They cannot be used to limit the scope of the present invention. All simple equivalent changes and modifications made based on the patent scope of the present invention and the contents of the patent specification are still within the scope of the present invention. within the scope covered by the patent of this invention.
