The lens unit. 4 includes a lens member 41 having an inner surface 411 and an outer surface 412 opposite to the inner surface 411 and two temple members 42 extending rearwardly from two lateral sides of the lens member 41. The lens member 41 is formed with a plurality of slots 413 extending through the inner and outer surfaces 411, 412.
The frame unit 5 includes a nose bridge pad 51 having an inverted-V shape, two lower frame members 52 respectively extending from two ends of the nose bridge pad 51 and respectively connected to the connecting units 7, and an upper frame member 53 disposed above the lower frame members 52 and interconnecting the connecting units 7. The nose bridge pad 51, the lower frame members 52 and the upper frame member 53 cooperate with one another to define a lens receiving space 54 confining the lens member 41 therein. The material for making the frame unit 5 can be one of plastic, silica gel, rubber and a combination thereof and the present disclosure is not limited to the material for making the frame unit 5.
The engaging unit 6 extends from the frame unit 5 toward the lens unit 4, and includes two positioning members 61 that extend respectively from upper and lower sides of the frame unit 5 and that detachably engage the slots 413 of the lens member 41. In this embodiment, the eyewear attachment 9 includes two engaging units 6 that are symmetrically disposed relative to the nose bridge pad 51. For the purpose of illustration, the upper ones of the positioning members 61 of the engaging units 6 are denoted by 61A and the lower ones of the positioning members 61 are denoted by 61B in the following description. The positioning members 61B extending respectively from the lower frame members 52 of the frame unit 5 are inclined forwardly and upwardly, and engage respectively the slots 413 formed in a lower portion of the lens member 41. The positioning members 61A extending from the upper frame member 53 of the frame unit 5 are inclined forwardly and downwardly, and engage respectively the slots 413 formed in an upper portion of the lens member 41, so that the frame unit 5 is affixed on the lens unit 4 by the engaging units 6. With the positioning members 61A, 61B extending inclinedly the lens member 41 is positioned relative to the frame unit 5. It should be noted that the configurations of the positioning members 61A, 61B are not limited to the example described herein and may be varied in other embodiments as long as the positioning members 61 are capable of engaging the lens member 41 for affixing the lens unit 4 to the frame unit 5.
The connecting units 7 are respectively and integrally connected to two lateral sides of the frame unit 5. Each of the connecting units 7 defines a temple passage opening 71 engaging a respective one of the temple members 42 so that lateral movement of the lens unit 4 relative to the connecting units 7 is prevented.
The wearing unit 8 interconnects the connecting units 7 so as to allow an assembly of the frame unit 5, the connecting units 7 and the wearing unit 8 to be sleeved on the head of a user. Note that the wearing unit 8 is one of an elastic band and a length adjustable strap with a buckle that can be adjusted to fit different sizes of the heads of different users. In this embodiment, the wearing unit 8 is connected to the frame unit 5 by the connecting units 7, so that assembly of the wearing unit 8 to the frame unit 5 is not required.
Before the lens unit 4 is attached to the eyewear attachment 9, an assembly of the frame unit 5 and the wearing unit 8 is sleeved on the head of the user. Then, the temples 42 of the lens unit 4 are brought to extend through the temple passage openings 71 of the connecting units 7, respectively. Subsequently, the positioning members 61A, 61B are snapped into the slots 314 so as to affix the lens unit 4 on the frame unit 5, and thus the eyewear assembly can be served as goggles, sports goggles, etc. In this way, the lens unit 1 is confined in the lens receiving space 54 by the engaging units 6, the connecting units 7 provide lateral engaging force to the temple members 42, and the wearing unit 8 provides positioning force in the front-rear direction.
To take off the eyewear assembly, the wearing unit 8 is pulled away from the head of the user and then the eyewear assembly can be worn around the neck of the user. When it is not required to enhance the connection strength between the lens unit 4 and the head of the user, the wearing unit 8 is first pulled away from the head of the user and then the lens unit 4 is detached from the frame unit 5 so that the lens unit 4 can be worn directly on the head of the user as a pair of glasses. Additionally, the eyewear attachment 9 can be worn around the neck of the user or be folded and stored. As compared to the conventional band 3 including two clips 31 shown in

In this embodiment, the engaging units 6 further include two inclined auxiliary members 62 extending forwardly, upwardly and outwardly from the two ends of the nose bridge pad 51, respectively, and abutting against the outer surface 412 of the lens member 41. By virtue of the auxiliary members 62, positioning force in the front-rear direction can be generated so that movement of the lens member 41 relative to the frame unit 5 in the front-rear direction can be prevented. In addition, an airflow from the ambient surrounding that may render the user uncomfortable can be blocked by the auxiliary members 62.
In the second embodiment, the upper frame member 53 of the frame unit 5 has an upper frame body 530 abutting against the outer surface 412 of the lens member 41 and at least one upper inclined toothed structure 531 extending from the upper frame body 530 and abutting against the inner surface 411 of the lens member 41. The lower frame members 52 of the frame unit 5 has a lower frame body 520 abutting against the outer surface 412 and at least one lower toothed structure 521 extending from the lower frame body 520 and abutting against the inner surface 411 of the lens member 41. The lower and upper frame bodies 520, 530 and the lower and upper toothed structures 521, 531 cooperate with one another to generate positioning force in the front-rear direction, so as to prevent removal of the lens member 41 from the frame unit 5.
Referring to
To sum up, by virtue of the positioning members 61A, 61B of the engaging unit 6 extending inclinedly, the lens unit 4 can be positioned relative to the frame unit 5. Further, the structure of the connecting units 7 integrally connected to two lateral sides of the frame unit 5 provides lateral engaging forces to position the lens unit 4, and the wearing unit 8 provides positioning force in the front-rear direction, thereby stabilizing the connection between the lens unit 4 and the frame unit 5. In this way, the present disclosure provides an eyewear assembly that is relatively simple to assemble and convenient to be carried by the user.
