Description

Technical Field

[0001] The present invention relates to a spectacle frame device, in particular to a spectacle frame device which can be worn on the head to arrange lenses or displays in front of the eyes and a temple thereof. Background Art

[0002] Conventional eyeglass frames are usually equipped with lenses or displays to be used as ordinary glasses or head-mounted devices such as augmented reality (AR) glasses and virtual reality (VR) glasses. However, when a user wears the eyeglass frame, they often feel uncomfortable because the size of the eyeglass frame does not fit the head shape, which makes the user unable to wear the eyeglass frame for a long time. In addition, the eyeglass frame is easy to slip off the user's head. Summary of the invention

[0003] The object of the present invention is to provide a temple that can solve at least one of the above problems.

[0004] The mirror foot of the present invention comprises a mirror foot body and a clamp.

[0005] The clamp is arranged at the rear end of the mirror base body and includes a clamping structure extending from front to rear and capable of bending. The clamping structure includes 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 spacing between the first side wall and the second side wall gradually decreases from front to rear. The two opposite ends of the horizontal column are respectively connected to the first side wall and the second side wall. The horizontal columns are arranged at intervals from front to rear and their left and right widths decrease gradually.

[0006] When a contact force toward the second side wall is applied to the side of the first side wall adjacent to the mirror base body, the cross column will be driven to rotate backward with the connection between the cross column and the first side wall as a fulcrum, so that the side of the clamping structure away from the mirror base body is bent in a direction opposite to the direction of application of the contact force.

[0007] The temples of the present invention further include a pivot shaft vertically penetrating the rear end of the temple body. The clamp also includes a pivot member that can be connected to the pivot shaft so as to rotate left and right. The clamping structure is provided on the side of the pivot member away from the temple body. When the contact force is applied to the side of the first side wall adjacent to the temple body, the clamping structure rotates with the pivot shaft as the axis in the direction opposite to the direction in which the contact force is applied, and drives the cross column to rotate backward with the connection between the cross column and the first side wall as the fulcrum, so that the side of the clamping structure away from the temple body is bent in the direction opposite to the direction in which the contact force is applied.

[0008] In the temples of the present invention, each of the horizontal columns has two joints respectively connected to the first side wall and the second side wall, and support portions respectively connected to the joints at left and right ends. The thickness of the joints in the extending direction of the clamping structure is smaller than the thickness of the support portions in the extending direction of the clamping structure.

[0009] In the temple of the present invention, the front side surface of the joint portion is flush with the front side surface of the supporting portion.

[0010] In the temple of the present invention, the front side surface and the rear side surface of the joint portion are both located between the front side surface and the rear side surface of the supporting portion.

[0011] The temples of the present invention, the clamp further comprises a soft cover covering the clamping structure to cover the crossbar.

[0012] For the temple of the present invention, the angle between the first side wall and any one of the transverse pillars is greater than the angle between the second side wall and any one of the transverse pillars.

[0013] For the temple of the present invention, the angle between the first side wall and any one of the transverse pillars is equal to the angle between the second side wall and any one of the transverse pillars.

[0014] Another object of the present invention is to provide a spectacle frame device having the aforementioned temples.

[0015] The spectacle frame device of the present invention is suitable for being worn on the head of a user. The spectacle frame device comprises a spectacle frame and two aforementioned spectacle legs.

[0016] The temples are respectively arranged on the left and right sides of the mirror frame, and the temple body of each temple extends backward from the mirror frame.

[0017] Among them, when the eyeglass frame device is worn on the head of the user, the first side wall of each temple adjacent to the side of the corresponding temple body will be exerted with the contact force toward the corresponding second side wall by the head of the user, and drive the corresponding cross column to rotate backward with the connection between the corresponding cross column and the corresponding first side wall as a fulcrum, so that the side of the corresponding clamp away from the corresponding temple body is bent in the direction opposite to the direction of application of the contact force to fit the head of the user.

[0018] The beneficial effect of the present invention is that: through the characteristic that the clamping structure bends toward the force-bearing position after being subjected to force, the clamping device can adaptively fit the head contour of the user, and the curvature of the clamping device can be adjusted according to the different head shapes of the users, thereby achieving a good effect of wearing comfort. In addition, through the characteristic that the clamping device automatically bends and fits the rear edge of the user's head after being subjected to force by the user's head, the eyeglass frame device cannot slide forward, thereby achieving a stable wearing effect.

[0028] The present invention is described in detail below with reference to the accompanying drawings and embodiments.

[0029] See also Figures 1 to 5 , is an embodiment of the eyeglass frame device of the present invention. First, define the directional terms used in the description herein. In the subsequent description, 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 top in the figure is defined as the third direction Z. The eyeglass frame device is suitable for being provided with components not shown in the figure, such as lenses or displays, and is worn on the head of a user 9. The eyeglass frame device includes a frame 100 suitable for being provided in front of the eyes of the user 9 and extending in the first direction X, and two temples 200 respectively provided on the left and right sides of the frame 100 and corresponding to the left and right sides of the head of the user 9. Subsequently, for the convenience of explanation and to simplify the description, Figure 1 The temple 200 on the left side is defined as temple 200a. Figure 1 The temple 200 located on the right side in FIG. 2 is defined as the temple 200b. Figures 2 to 4 In the figure, the temple 200a is taken as an example, and the temple 200b is symmetrical with the temple 200a in terms of structural configuration, which will not be described in detail here.

[0030] See also Figures 1 to 4 Each of the mirror feet 200 includes a mirror foot body 1 extending backward from the mirror frame 100 (i.e. extending along the second direction Y), a pivot 2 vertically penetrating the rear end of the mirror foot body 1, and a clamp 3 disposed at the rear end of the mirror foot body 1. The mirror foot body 1 can be in a rod-like, plate-like or other form, and is not limited to a specific form. In addition, each of the pivots 2 extends in the third direction Z. Each of the clamps 3 includes a pivot 4 that can be connected to the pivot 2 so as to be rotatable left and right, a clamping structure 5 that extends from the side of the pivot 4 away from the mirror foot body 1 from the front to the back (toward the second direction Y) and can be bent, and a connecting member 6 that can be inserted into the pivot 4. In other words, each of the pivots 4 can rotate in the first direction X or in the direction opposite to the first direction X with the corresponding pivot 2 as the axis. In this embodiment, the connecting member 6 is used to detachably fix the clamping structure 5 to the pivoting member 4, but in other embodiments, the connecting member 6 may be omitted. That is, the clamping structure 5 is connected to the pivoting member 4.

[0031] See also Figure 1 , Figures 3 to 5Each of the clamping structures 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 transverse columns 53 located between the first side wall 51 and the second side wall 52 and having different widths in the first direction X. Specifically, the first side wall 51 and the second side wall 52 of each of the clamping structures 5 are located on the left and right sides of the clamping structure 5, respectively. And the first side wall 51 of each of the clamping structures 5 extends along the extension direction of the corresponding mirror base body 1 in the second direction Y (see Figure 1 ), and the second side wall 52 of each clamping structure 5 extends obliquely backward from the side of the corresponding pivot member 4 away from the first side wall 51 to connect to the first side wall 51, so that the cross section of each clamping structure 5 presents a hollow triangle with a horizontal bar in the middle. In other words, the distance between the first side wall 51 and the second side wall 52 of each clamping structure 5 gradually decreases along the second direction Y.

[0032] See also Figures 4 to 6 , the two opposite ends of the transverse column 53 of each of the clamping structures 5 are respectively connected to the side surfaces of the corresponding first side wall 51 and the corresponding second side wall 52 facing each other. Moreover, the transverse columns 53 of each of the clamping structures 5 are arranged at intervals along the second direction Y, and the width of the transverse column 53 of each of the clamping structures 5 in the first direction X will decrease corresponding to the gradually shrinking interval between the first side wall 51 and the second side wall 52. In this way, when the user 9 wants to wear the eyeglass frame device on the head of the user 9, the temples 200 will be respectively arranged on the left and right sides of the head of the user 9, and the first side wall 51 of each of the temples 200 is adjacent to one side of the corresponding temple body 1 (i.e. Figure 5 The position in contact with the head of the user 9) will be exerted with a contact force F (such as Figure 5 In addition, when the contact force F is applied to each first side wall 51 toward the corresponding second side wall 52, the corresponding first side wall 51 will drive the corresponding cross column 53 to rotate backwards with the connection between the cross column 53 and the first side wall 51 as the fulcrum, and the shorter the left and right width of the cross column 53 in the first direction X, the greater the amplitude of its rotation in the first direction X or in the direction opposite to the first direction X. In this way, the side of the corresponding clamping structure 5 away from the corresponding mirror base body 1 (i.e., the rear end of the clamping structure 5, or the tip of the clamping structure 5) will be as follows: Figure 5 The transition state shown is bent in the direction opposite to the direction in which the contact force F is applied, and is transformed into Figure 6In the usage state shown, the clamp 3 fits the head of the user 9 and can provide a clamping force to clamp the head of the user 9.

[0033] In this embodiment, the material of the clamping structure 5 can be a thermoplastic material with good ductility, such as polylactic acid (PLA) or polypropylene (PP), or a rubber material (TPA), nylon, titanium, or other ductile materials, not limited to the above description. The clamping structure 5 can be made by one-piece molding, such as injection molding, to have better structural stability and reduce production costs, but the clamping structure 5 can also be composed of a plurality of components, not limited to a specific form.

[0034] See also Figure 3 , Figure 7 In one implementation of this embodiment (see Figure 3 ), the number of the crossbars 53 is nine. The more the number of the crossbars 53, the better the support of the clamping structure 5. However, in another embodiment of the present invention (see Figure 7 ), the number of the crossbars 53 may also be relative to Figure 3 The number of patterns is reduced (five examples are given here), so that the clamping structure 5 can be bent more easily.

[0035] See also Figure 3 , Figure 4 Preferably, each of the transverse pillars 53 has two joints 531 connected to the corresponding first side wall 51 and the corresponding second side wall 52 and capable of being bent, and a support portion 532 connected to the joints 531 at the left and right ends. The thickness of the joints 531 of each of the clamping structures 5 in the extension direction of the clamping structure 5 (the second direction Y) is smaller than the thickness of the support portion 532 of each of the clamping structures 5 in the extension direction of the clamping structure 5 (i.e., the second direction Y), so that the clamping structure 5 can be more easily rotated with the joints 531 as a fulcrum. In other words, when the first side wall 51 of each of the clamping structures 5 is applied with the contact force F and drives the corresponding transverse pillar 53 to rotate backward, the corresponding transverse pillar 53 will rotate backward with the joints 531 adjacent to the first side wall 51 as a fulcrum, so that the corresponding clamping structure 5 can be bent more easily.

[0036] See also Figure 3 , Figure 4 , Fig. 9 Specifically, in this embodiment Figure 3 , Figure 4 In the embodiment of the present invention, the front side and the rear side of the joint portion 531 are both located between the front side and the rear side of the support portion 532. In this way, the front and rear sides of the crossbar 53 (corresponding to the joint portion 531) form a notch-like design, making it easy for the clamping structure 5 to rotate backward. Fig. 9 ), the clamping structure 5 can also be designed so that the front side surface of the joint portion 531 is flush with the front side surface of the support portion 532, and the rear side surface of the cross column 53 (corresponding to the position of the joint portion 531) will still form a notch-like design, which can also make the clamping structure 5 easy to rotate backward.

[0037] See also Figure 3 , Figure 4 , Figure 8 Preferably, in this embodiment Figure 3 , Figure 4 In the embodiment, the angle θ1 between the first side wall 51 of each clamping structure 5 and any one of the cross pillars 53 is greater than the angle θ2 between the second side wall 52 and any one of the cross pillars 53. For example, the shape of the clamping structure 5 is similar to a right triangle, and the angle θ1 between the first side wall 51 of each clamping structure 5 and any one of the cross pillars 53 is 90 degrees, while the angle θ2 between the second side wall 52 of each clamping structure 5 and any one of the cross pillars 53 is less than 90 degrees. In this way, the length of the second side wall 52 in the second direction Y is greater than the length of the first side wall 51 in the second direction Y, so that the clamping structure 5 can only bend toward the outside of the first side wall 51. However, in another embodiment of the present embodiment (see Figure 8 ), each of the clamping structures 5 may also be designed such that the angle θ1 between the first side wall 51 and any one of the transverse pillars 53 is equal to the angle θ2 between the second side wall 52 and any one of the transverse pillars 53. In other words, the first side wall 51 and the second side wall 52 are equal in length in the second direction Y and are bilaterally symmetrically arranged (the shape of the clamping structure 5 is similar to an isosceles triangle), so that the clamping structure 5 can be bent toward the outside of the first side wall 51 or toward the outside of the second side wall 52.

[0038] Furthermore, the clamping structure 5 is disposed on a side of each of the pivot members 4 away from the mirror base body 1. When the contact force F is applied to a side of the first side wall 51 of each of the clamping structures 5 adjacent to the mirror base body 1, the clamping structure 5 will first rotate with the pivot 2 as the axis in the direction opposite to the direction in which the contact force F is applied, so that the contact area between the clamping structure 5 and the head of the user 9 increases, thereby increasing the magnitude of the contact force F. Then, the horizontal column 53 is affected by the increase in the contact force F and rotates backward to increase the amplitude, so that the bending force of the side of the clamping structure 5 away from the mirror base body 1 in the direction opposite to the direction in which the contact force F is applied increases, thereby increasing the clamping force applied by the clamping structure 5 to the head of the user 9.

[0039] Preferably, each of the clamps 3 further comprises a soft cover 7. Each of the soft covers 7 can be flexibly covered on the corresponding clamping structure 5 to shield the corresponding cross column 53, so that foreign matter cannot enter the space between the corresponding cross column 53, the corresponding first side wall 51 and the corresponding second side wall 52, so as to avoid affecting the bending of the corresponding clamping structure 5.

[0040] In summary, the clamping structure 5 will bend toward the force-bearing position after being subjected to force, so that the clamping device 3 can adaptively fit the head contour of the user 9, and the curvature of the clamping device 3 can be adjusted according to the different head shapes of the user 9, thereby achieving a good effect of comfort when wearing. In addition, the clamping device 3 will automatically bend and fit the rear edge of the head of the user 9 after being subjected to force by the head of the user 9, so that the eyeglass frame device cannot slide forward, thereby achieving a stable wearing effect, and thus the purpose of the present invention can be achieved.
