Please refer to FIG. 1 and FIG. 2, an exploded view and a perspective view of an eyeglasses with quick detachable structure according to one embodiment of the instant disclosure are shown. As shown in FIG. 1 and FIG. 2, eyeglasses with quick detachable structure includes a lens 10 and two temples 20. The two temples 20 are pivotally detachable from two ends A1 of the lens 10.
More specifically, two opposite sides at the two ends A1 of the lens 10 are defined as two terminal sides 101 respectively. Two ends A1 of the lens 10 are formed with two recesses 11 adjacent to the terminal sides 101 respectively. Each of the two temples 20 has a temple arm 21 and a pivotal-connecting portion 22. One end of each temple arm 21 is disposed with the pivotal-connecting portion 22, and the pivotal-connecting portion 22 comprises a wedge unit 23. The two temples 20 are detachably attached to both ends A1 of the lens 10 through the wedge units 23 of the pivotal-connecting portions 22. In other words, the two wedge units 23 of two connecting portions 22 are wedged with the two recesses 11 of the lens 10, so the two temples 20 are detachably attached to both ends A1 of the lens 10.
Please refer to FIG. 3, as shown in FIG. 3, the pivotal-connecting portion 22 of each of the temples 20 includes a front cover 221 and a back cover 222. The front cover 221 is connected to the back cover 222 with spacing, and the wedge unit 23 is formed in a gap S between the first cover 221 and the back cover 222. In the preferred embodiment, the radial length of the front cover 221 and the radial length of the back cover 222 are unequal. The front cover 221 and the back cover 222 fully cover the wedge unit 23. As shown in FIG. 2 through FIG. 4, at least part of the lens 10 wedges the gap S when the temples 20 attaches to the lens 10. The front cover 221 and the back cover 222 of the pivotal-connecting portion 22 are corresponding to the front side and the back side of the lens 10 respectively.
To put it concretely, referring to FIG. 5 and FIG. 6, partial exploded views of the temple 20 and the lens 10 are shown, wherein the front cover 221 (as shown in FIG. 3) of the connecting portion 22 in FIG. 5 and FIG. 6 is omitted for clarification purpose. As shown in FIG. 5 and FIG. 6, each of the recesses 11 is formed with a first protrusion 111 and a second protrusion 112 at two first inner ends of the lens 10 adjacent to the corresponding terminal side 101. The first protrusion 111 is disposed adjacent to the upper edge 102 of the lens 10, and the second protrusion 112 is disposed adjacent to the lower edge 103 of the lens 10.
In this embodiment, one side away from the terminal side 101 of the first protrusion 111 is adjacent to a first niche 113, and another one side away from the terminal side 101 of the second protrusion 112 is adjacent to a second niche 114. That is, each of the recesses 11 is also formed with the first niche 113 and the first niche 114 on second inner ends of the lens 10 away from the corresponding terminal side 101 and adjacent to the corresponding first protrusion 111 and the corresponding second protrusion 112 respectively. An auxiliary niche 115 formed on the lens 10 is connected between the first niche 113 and the second niche 114 and is configured to enhance the wedging force of the wedge unit 23 and the recess 11. In other words, in this embodiment, there are three niches formed in the inner side of the recess 11. However, the recess 11 may be, but not limited to, is designed to be formed with merely two niches (e.g. the first niche 113 and the second niche 114); or alternatively, the recess 11 may be formed with more than four niches (e.g. the first niche 113, the second niche 114, and two auxiliary niches 115, wherein the two auxiliary niches 115 are connected to each other). Certainly, the shapes of the niches can be varied according to the actual requirements, and the shapes of the niches in the drawings are just one implementation among several embodiments.
It is noted that a distance D1 from a top end of the first protrusion 111 to a top end of the second protrusion 112 is smaller than a distance D2 from a bottom end of the first niche 113 to a bottom end of the second niche 114. In other words, a radial length of an opening at the terminal side 101 formed between the corresponding first protrusion 111 and the corresponding second protrusion 112 is smaller than a radial length of an inner space of the recess 11. Preferably, a longitudinal height H1 of the first protrusion 111 is greater than a longitudinal height H2 of the second protrusion 112.
The wedge unit 23 of the temple 20 includes a shallow groove wall 231, a deep groove wall 232, a settling bump 233, and a wedging bump 234. The shapes of the shallow groove wall 231, the deep groove wall 232, the settling bump 233, and the wedging bump 234 are corresponding to the shapes of the first protrusion 111, the second protrusion 112, the first niche 113, and the second niche 114 respectively, so the shallow groove wall 231, the deep groove wall 232, the settling bump 233, and the wedging bump 234 are wedged with the first protrusion 111, the second protrusion 112, the first niche 113, and the second niche 114. Referring to FIG. 6, preferably, the depth V1 of the shallow groove wall 231 is smaller than the depth V2 of the deep groove wall 232. A distance D3 from a bottom end of the shallow groove wall 231 to a bottom end of the deep groove wall 232 is smaller than a distance D4 from a top end of the settling bump 233 and a top end of the wedging bump 234. A distance D4 from the top end of the settling bump 233 to the top end of the wedging bump 234 is not greater than the distance D2 from the bottom end of the first niche 113 to the bottom end of the second niche 114. The distance D1 from the top end of the first protrusion 111 to the top end of the second protrusion 112 is smaller than the distance D3 from the bottom end of the shallow groove wall 231 to the bottom end of the deep groove wall 232.
In other words, when the wedge unit 23 wedges the recess 11, the shallow groove wall 231, the deep groove wall 232, the settling bump 233, and the wedging bump 234 are wedged with first protrusion 111, the second protrusion 112, the first niche 113, and the second niche 114 in presentation of a semi-sophisticated joint. However, the lens 10 may be broken if the abovementioned wedge unit 23 wedges the recess 11 in presentation of a sophisticated joint.
It is noted that, as shown in FIG. 7, an angle between the terminal side 101 of the lens 10 and the upper edge 102 of the lens 10 in the embodiment is an obtuse angle, and the terminal side 101 is inclined to the upper edge 102, so an opening 11a formed in the recess 11 of the terminal side 101 slopes toward the upper edge 102, and the temple 20 can be smoothly attached to the lens 10. In short, in the preferred embodiment, the centre line of the recess 11 formed on the terminal side 101 of the lens 10 is inclined to the upper edge 102 of the lens 10. In this embodiment, the wedge unit 23 further comprises an auxiliary bump 235 formed between the settling bump 233 and the wedging bump 234. The shape of the auxiliary bump 235 is corresponding to the shape of the auxiliary niche 115 of the recess 11. The auxiliary bump 235 wedges the auxiliary niche 115 to enhance the wedging force between the wedge unit 23 and recess 11. Certainly, in other embodiments, the shape and the number of the auxiliary bump 235 can vary according to the actual requirements.
Referring to FIG. 8 through FIG. 10, schematic diagrams for illustrating a wedging action interacted by the temple 20 and the lens 10 are shown. As shown in FIG. 8, the user firstly wedges the first protrusion 111 of the lens 10 within the shallow grove wall 231 of the wedge unit 23 of the temple 20. Then, the temple side bar 20 rotates toward the lens 10 (i.e. the rotating direction L1 as shown in the drawings) around the a position which the shallow groove wall 231 is wedged with the first protrusion 111. When one side of the wedging bump 234 abuts against one side of the second protrusion 112, part of the wedge unit 23 (i.e. the settling bump 233, the wedging bump 234, auxiliary bump 235, and a notch between the wedging bump 234 and the auxiliary bump 235) are received into the recess 11. In other words, when the temple 20 and lens 10 are disposed in the status of FIG. 8, the distance D1 from the top end of the first protrusion 111 to the top end of the second protrusion 112 is greater than a distance D5 from the bottom end of the shallow groove wall 231 to bottom end of a notch between the wedging bump 234 and the auxiliary bump 235, and a distance D6 from the bottom end of the shallow groove wall 231 to the top end of the wedging bump 234 is greater than the distance D1 from the top end of the first protrusion 111 to the top end of the second protrusion 112.
As shown in FIG. 9, when the user rotates the temple 20 as shown in FIG. 8 further toward the lens 10 (i.e. the rotating direction L1 as shown in the drawings), part of the wedging bump 234 enters the recess 11 through the second protrusion 112, and part of the top end of the wedging bump 234 abuts against the top end of the second protrusion 112, so the temple 20 wedges the lens 10. Referring to FIG. 10, when the user rotates the temple 20 in FIG. 9 further toward the rotating direction L1, the wedging bump 234 entirely enters the recess 11 through the second protrusion 112. Meanwhile, the first protrusion 111, the second protrusion 112, the first niche 113, the second niche 114, and the auxiliary niche 115 wedge the shallow groove wall 231, the deep groove wall 232, the settling bump 233, the wedging bump 234, and the auxiliary bump 235 respectively, so the temple 20 is secured within lens 10 stably. It is noted that, when the wedge unit 23 of the temple 20 wedges the recess 11 of the lens 10, the top ends of the first protrusion 11 and the second protrusion 112 entirely enter the shallow groove wall 231 and the deep groove wall 232 respectively. In other words, part of the shallow groove wall 231 and the deep groove wall 232 abut against the terminal side 101 of the lens 10.
More specifically, as shown in FIG. 10, in practice, when the temple 20 wedges the lens 10, at least three of the first protrusion 111, the second protrusion 112, the first niche 113, the second niche 114, and the auxiliary niche 115 preferably abut against the corresponding structure of the wedge unit 23 (the shallow groove wall 231, the deep groove wall 232, the settling bump 233, the wedging bump 234, and the auxiliary bump 235), such that when the temple 20 is secured within the lens 10, the more stable wedging relation of the temple 20 and the lens 10 is obtained, and the it is hard to cause a shake between the temple 20 and the lens 10.
As shown in FIG. 10, by contrast, when the user wants to detach the temple 20 from the lens 10, the user can rotates the temple 20 away from the lens 10 (i.e. the rotating direction L2 in the drawings), such that the temple 20 is rotated toward the rotating direction L2 around a position which the shallow groove wall 231 wedges the first protrusion 111, the status of the temple 20 and the lens 10 in FIG. 10 is sequentially changed to the statuses in FIG. 9 and FIG. 8, and the temple 20 is detached from the lens 10. It is noted that, as shown in FIG. 10, when the temple 20 wedges the lens 10, a gap (not shown in the drawings) exists between the settling bump 233 and the first niche 113, and the gap particularly exists at a rotating path which the temple 20 is rotated toward the rotating direction L2, so the temple 20 is detached from the lens 10 quickly and easily.
In practice, a connection portion between the shallow groove wall 231 and the settling bump 233 is relatively sloped, and a connection portion between the deep groove wall 232 and wedging bump 234 is relatively smooth, so the temple 20 can be easily detached from the lens 10. In a specific application, a distance (not shown in the drawings) from a bottom end of a notch formed between the settling bump 233 and the auxiliary bump 235 to the top end of the wedging bump 234 is designed to be greater than a distance from the top end of the first protrusion 111 to the top end of the second protrusion 112, such that when the user attaches the temple 20 to the lens 10, the second protrusion 112 cannot firstly be wedged with the shallow groove wall 232 since the settling bump 233 abuts against outside the first protrusion 111 meanwhile. The user must attach the temple 20 to the lens 10 by the manner shown by FIG. 8 through FIG. 10, and the attaching manner of the user is limited to avoid the user from attaching the temple 20 in the incorrect direction.
In summary, in eyeglasses with quick detachable structure of the present disclosure, by designing the recesses in the lens and wedge unit in the temple, the temple can be quickly detached from and attached to the lens. Thus, the lens or the temple can be replaced quickly in response to the user's demands.
