This application claims priority to Taiwanese Utility Model Patent Application No. 109205380, filed on May 5, 2020.
The disclosure relates to an eyeglasses assembly, and more particularly to an eyeglasses assembly with removable lens.
Referring to
However, the third securing member 113 of the conventional eyeglasses has a complex and fragile structure that is costly to manufacture. Moreover, if the third securing member 113 is damaged by impact or collision with an external force, the securing section 115 may not be able to stably engage with the affixing channel 116, which will cause the pivot section 114 to be unable to stably affix the third protrusion 134. Additionally, the first securing member 111 and the second securing member 112 are loosely engaged with the first protrusion 132 and the second protrusion 133 of the lens 13, so that the lens 13 cannot be secured to the frame 11 with these engagements alone without the engagement between the third securing member 113 and the third protrusion 134 of the lens 13. In other words, the lens 13 may not be secured to the frame 11 if the third securing member 113 of the frame 11 is damaged.
Therefore, an object of this disclosure is to provide an eyeglasses assembly that has a simple structure, that is economic to manufacture, and that is durable and unlikely to be damaged from impact.
According to the disclosure, an eyeglasses assembly includes a frame, an attachment unit, and a lens. The frame includes a frame body and a positioning column. The frame body is formed with a frame groove that has an opening facing downwards and that is elongated along the frame body between left and right end portions of the frame body, and two engaging grooves that are respectively disposed at the left and right end portions of the frame body. The positioning column is disposed in the frame groove and extends in a front-rear direction. The attachment unit is connected to opposite ends of the frame and is adapted to secure the frame to a user's face. The lens has a main portion that removably engages with the frame groove of the frame body of the frame, and that is formed with a lens groove extending downwards from a top end of the main portion. The main portion is further formed with a securing groove that extends perpendicularly from the lens groove. The lens further has a protruding portion extending from the main portion and engaging removably with one of the engaging grooves, and a second protruding portion opposite to the first protruding portion, extending from the main portion, and engaging removably with the other one of the engaging grooves. The securing groove extends from the lens groove towards the second protruding portion.
The lens is movable relative to the frame between an initial position, where the positioning column is disposed at an intersection of the lens groove and the securing groove, and a fixed position, where the positioning column is disposed at an end of the securing groove which is distal from the lens groove such that the second protruding portion of the lens is allowed to be disengaged from the other one of the engaging grooves.
Other features and advantages of the disclosure will become apparent in the following detailed description of the embodiments with reference to the accompanying drawings, of which:
The frame 2 of the eyeglasses assembly includes a frame body 21 formed with a frame groove 201. The frame groove 201 has an opening facing downwards and is elongated along the frame body 21 between left and right end portions of the frame body 21. The frame body 21 is further formed with two engaging grooves 202(a), 202(b) that are respectively disposed on the left and right end portions of the frame body 21. The frame 2 further includes a positioning column 22 disposed in the frame groove 201 and extending in a front-rear direction. The frame body 21 includes a front wall 211, and a back wall 212 opposite to the front wall 211 in the front-rear direction. The front wall 211 cooperates with the back wall 212 to define the frame groove 201. In the present embodiment, the positioning column 22 is perpendicular to the front wall 211 and the back wall 212, and the frame body 21 and the positioning column 22 are integrally formed as one piece. However, in other embodiments the positioning column 22 may not be perpendicular to the front wall 211 and the back wall 212, and the frame 2 may not be integrally formed as one piece, instead, the frame body 21 and the positioning column 22 may be formed as separate pieces.
It should be mentioned that when the frame body 21 and the positioning column 22 are integrally formed as one piece, the overall structural strength of the frame 2 will be increased which not only lowers the probability of the frame 2 being damaged from impact, but also decreases the amount of raw materials required to manufacture the frame 2, thereby lowering the cost of manufacture.
In the present embodiment, the attachment unit 3 is substantiated by two temples respectively connected to two opposite elongated ends of the frame 2 via pivot connections (as shown in
Referring to
In the present embodiment, referring further to
In the present embodiment, the nose pad 4 is connected to the frame 2 in the center of the back wall 212, where it assists the attachment unit 3 in securing the frame 2 to the user's nose. The nose pad 4 can be adjusted according to requirements of the user. Therefore, in other embodiments, the nose pad 4 may be connected to the main portion 51 of the lens 5, where it will become removable from the frame 2 along with the lens 5. It should be noted that location of the nose pad 4 on the eyeglasses assembly should not be limited to the positions discussed above, and the nose pad 4 may be attached on any position suitable for securing the eyeglasses assembly to the user's face.
The lens 5 can then be pushed transversely relative to the frame 2 from the initial position to a fixed position as shown in
When the lens 5 is in the initial position, the second protruding portion 53 is not allowed to be engaged with the engaging groove 202(b). When the lens 5 is pushed to the fixed position, the centerline (C) of the lens 5 is shifted to be closer to the engaging groove 202(a), and the second protruding portion 53 is more proximate to the engaging groove 202(b) than in the initial position. At this time, the second protruding portion 53 of the lens 5 is allowed to be engaged with the engaging groove 202 (b).
Additionally, due to the shape of the distal end of the securing groove 512 matching the contour of the positioning column 22 when viewed from the front of the eyeglasses assembly, the lens 5 can be securely attached on the frame 2. Finally, to complete the assembly of the eyeglasses assembly the lens 5 is pushed so that the second protruding portion 53 engages with the other one of the engaging grooves 202(b), and the lens 5 is securely attached to the frame 2 as shown in
For disassembly of the present embodiment of the eyeglasses assembly, the assembly procedure is performed in reverse order. First, since the lens 5 is at the fixed position, the second protruding portion 53 is allowed to be disengaged from the engaging groove 202(b), so that the user can pull the lens 5 to release the second protruding portion 53 from engagement with the engaging groove 202(b) to the state shown in
It should be noted that in a variation of this embodiment, the first protruding portion 52 and the second protruding portion 53 can be made smaller. In such a case the eyeglasses assembly is assembled by first moving the positioning column 22 via the lens groove 511 to the intersection of the lens groove 511 and the securing groove 512, and then pushing the lens 5 so that the first protruding portion 52 is inserted into and engages with the engaging groove 202 (a). The remaining steps in the assembly procedure are the same as that of the previously described embodiment. The securing groove 512 being designed to be perpendicular to the lens groove 511 facilitates engagement between the first and second protruding portions 52, 53 and the engaging grooves 202(a), 202(b) of the frame 2. Additionally, the design of the securing groove 512 and the lens groove 511 provides a confining mechanism that stabilizes the device and ensures that the positioning column 22 is confined within the securing groove 512, thereby preventing the lens 5 from separating from the frame 2.
In another variation of this embodiment, the lens groove 511 may be formed on the centerline (C) of the lens 5. The assembly procedure for such variation is performed by engaging the positioning column 22 with the lens groove 511 and the securing groove 512 disposing the lens 5 at the initial position. The lens 5 is then pushed from the initial position to the fixed position. At this time, the second protruding portion 53 is proximate to the engaging groove 202(b) and the lens 5 can be pushed to engage the second protruding portion 53 with the engaging groove 202 (b). The lens 5 is then pushed once again to the initial position to move the first protruding portion 52 to be proximate to the engaging groove 202(a). The lens 5 can then be pushed to engage the first protruding portion 52 with the engaging groove 202(a) to thereby complete the assembly of such variation. The different assembly procedures described above show the cooperation of different components of the eyeglasses assembly, and describe how different assembly procedures may be taken to perform the assembly of the eyeglasses assembly. Flexibility of the eyeglasses assembly's assembly procedure allows the components of the eyeglasses assembly to be more diverse. For example, in some embodiments of the eyeglasses assembly, the lens groove 511 and the securing groove 512 may be formed at different locations or the first protruding portion 52 and the second protruding portion 53 can be made in different sizes and shapes or disposed on different locations of the eyeglasses assembly.
In summary, the eyeglasses assembly with removable lens has various straightforward assembling procedures where the positioning column 22 is movable within the lens groove 511 and the securing groove 512, that are designed to be substantially perpendicular to each other. The first protruding portion 52 and the second protruding portion 53 can respectively engage with the engaging grooves 202(a), 202(b) so that the lens 5 is securely attached to the frame 2. Additionally, due to the frame body 21 and positioning column 22 being integrally formed in one piece (in some embodiments of the eyeglasses assembly), the eyeglasses assembly is less costly to manufacture and structurally more sturdy. Because of the increase sturdiness, the probability of damaging the eyeglasses assembly from collision or impact with an external force is reduced.
