DETAILED DESCRIPTION OF THE INVENTION

[0038] As used herein in connection with the embodiment described below, directional terms such as left, right, front, rear, upper, and lower make reference to the orientations of the goggles in FIG. 2. Those directional terms are used only to facilitate description of the embodiment and are not intended to limit the spatial aspects of the present invention.

[0039] Referring to FIG. 1, FIG. 2, and FIG. 3, one embodiment of the present invention includes a first lens 1, a second lens 2, temple units 3, and soft sealing pads 4.

[0040] The first lens 1 has a middle portion provided with a first pivotal connection portion 11. An upper part of each of the two lateral sides of the first lens 1 is provided with a first coupling portion 12. Each first coupling portion 12 has an upper side and a lower side each provided with a first engaging hole 121 along a vertical direction Y. Each first coupling portion 12 is provided with a protruding plate 122 between the corresponding two first engaging holes 121. In addition, each of the two lateral sides (i.e., left and right sides) of the first lens 1 is extended with a transparent lateral window portion 13. Each lateral window portion 13 is provided with a first snap-fit portion 14 along a lateral side and a bottom portion of the lateral window portion 13, and each first snap-fit portion 14 is provided with a plurality of snap-fit blocks 141 (see FIG. 6). The inner side of the first lens 1 defines a relatively large accommodating space 15 for accommodating a pair of eyeglasses with any of various common eyeglass frames that may be different in size (e.g., a pair of eyeglasses with a thick eyeglass frame, a pair of eyeglasses with a thin eyeglass frame, or a pair of frameless eyeglasses), with the first lens 1 covering the pair of eyeglasses. The first lens 1 is configured to accommodate and cover any eyeglasses the user wears, so the user will not have problem wearing the goggles together with, or putting on the goggles while wearing, a different pair of eyeglasses. Rather, the user will be able to put on the goggles conveniently and wear them along with a pair of eyeglasses of the user's choice during work or other activities.

[0041] The second lens 2 has a middle portion provided with a second pivotal connection portion 21. The second pivotal connection portion 21 is pivotally connected to the first pivotal connection portion 11 so that the second lens 2 can be flipped open with respect to the first lens 1. The second lens 2 may be a protective lens for use in a medical environment, an eye-protecting lens for use in an industrial environment, a sun-blocking lens like those of sunglasses, a lens for vision correction (e.g., for correcting nearsightedness), or a sports lens for use in a sports activity.

[0042] The two temple units 3 are each coupled to the corresponding one of the first coupling portions 12 on the two lateral sides of the first lens 1. Each temple unit 3 includes an adapter block 31 and a temple 32. Each adapter block 31 is provided with a second coupling portion 311 at one end, and each second coupling portion 311 has an upper side and a lower side each provided with a first engaging block 312 along the vertical direction Y. The two first engaging blocks 312 of each second coupling portion 311 are each engaged in the corresponding one of the two first engaging holes 121 of the corresponding first coupling portion 12 (see FIG. 4) so that each adapter block 31 can be rotated to the left and to the right with respect to the first lens 1. Each second coupling portion 311 further has a middle portion provided with a groove 313, and the groove 313 of each second coupling portion 311 is configured to receive and confine the protruding plate 122 of the corresponding first coupling portion 12, lest the two first engaging blocks 312 of the second coupling portion 311 move out of the two first engaging holes 121 of the corresponding first coupling portion 12 and thereby cause separation between the second coupling portion 311 and the corresponding first coupling portion 12. The opposite end of each adapter block 31 is provided with an insertion groove 314. Each insertion groove 314 is provided therein with a toothed rack section 315 along the vertical direction Y, and each insertion groove 314 has two lateral walls each provided with a second engaging hole 316 along a horizontal direction X. Each temple 32 is provided with an insertion plate 321 at one end, and the insertion plate 321 of each temple 32 is inserted into the insertion groove 314 of the corresponding adapter block 31 such that the temple 32 is limited in position while being allowed to rotate. More specifically, each insertion plate 321 has an end portion provided with a toothed block 322 meshing with the toothed rack section 315 of the corresponding insertion groove 314 (see FIG. 5), each insertion plate 321 further has two lateral sides each provided with a second engaging block 323 along the horizontal direction X, and each of the two second engaging blocks 323 of each insertion plate 321 is engaged in the corresponding second engaging hole 316 of the corresponding insertion groove 314 so that each temple 32 can be rotated upward and downward with respect to the corresponding adapter block 31. The first lens 1 and the temple units 3 are made of plastic, are put together by engagement between corresponding structures, and therefore need not be held together by metal screws or elastic elements. This makes it possible to achieve a lightweight design in which the assembled goggles weigh less than goggles using metal screws or elastic elements. More importantly, electrical hazards associated with the use of metal screws or elastic elements are also eliminated to reduce occupational safety accidents attributable to the conduction of electricity, thereby ensuring the highest safety of use.

[0043] The two soft sealing pads 4 are coupled to the first lens 1 in a detachable manner (see FIG. 6 and FIG. 7). Each soft sealing pad 4 is provided with a second snap-fit portion 41 along a lateral side and a bottom portion of the soft sealing pad 4, and each second snap-fit portion 41 is provided with a plurality of snap-fit holes 411. Each second snap-fit portion 41 is configured to form a snap-fit connection with the corresponding first snap-fit portion 14, with each snap-fit block 141 snap-fitted in the corresponding snap-fit hole 411 such that the soft sealing pads 4 are detachably coupled to the lateral sides and the corresponding bottom portions of the first lens 1.

[0044] Referring to FIG. 8 and FIG. 9 in conjunction with FIG. 1 and FIG. 3, when it is necessary for a user A to wear a pair of eyeglasses B and the goggles during work or a certain activity, the relatively large accommodating space 15 on the inner side of the first lens 1 can accommodate the eyeglasses B regardless of the size of their eyeglass frame as long as the frame is a common one, with the first lens 1 covering the eyeglasses B. Moreover, referring to FIG. 10, the second lens 2 can be flipped open with respect to the first lens 1 according to practical needs. Furthermore, referring to FIG. 11 in conjunction with FIG. 5, the goggles can be adjusted according to the size of the user A's face by rotating the temples 32 upward or downward with respect to the adapter blocks 31. With each toothed block 322 meshing with, slidable along, and stoppable at any tooth position of, the corresponding toothed rack section 315, the temples 32 can be rotated in stages with respect to the adapter blocks 31 and then held in place without further rotation. So, by vertically rotating, and thereby adjusting the positions of, the two temple units 3 with respect to the two lateral sides of the first lens 1, the goggles can be adapted to the shape of the user A's face and then worn on the face without getting loose or falling off.

[0045] As shown in FIG. 6, FIG. 7, and FIG. 8, the soft sealing pads 4 are configured to be in close contact with those areas of the user A's face that are on the outer lateral sides of, and below, the eyes in order to keep foreign objects from flying into the goggles while the user A is working, or prevent a patient's body fluid, bacteria, or virus from reaching the user A's eyes through a gap between the goggles and the user A's face while the user A is performing a medical operation, the objective being to preclude injury in an industrial environment or infection in a medical environment. The goggles, therefore, are particularly suitable for providing protection in a medical or industrial environment. The softness of the two soft sealing pads 4 also adds to the comfort of wear, the tightness of wear, and the anti-slip effect of the goggles so that the goggles can be worn for a long time without causing discomfort or becoming a burden.

[0046] With continued reference to FIG. 6 and FIG. 7, the two soft sealing pads 4, which are detachably coupled to the first lens 1, can be removed when no longer needed. To remove the two soft sealing pads 4, each snap-fit block 141 is forced out of the corresponding snap-fit hole 411 so that each second snap-fit portion 41 can be separated from the corresponding first snap-fit portion 14. Removal of the soft sealing pads 4 helps increase ventilation in the goggles while the goggles are being worn; that is to say, the goggles will not be fogged up with hot air and become blurred even if worn for an extended period of time or under a high temperature. This is an improvement over those conventional goggles whose closed lateral portions cannot be removed to improve ventilation.

[0047] Referring to FIG. 1, FIG. 2, and FIG. 8, the lateral window portions 13 on the left and right sides of the first lens 1 are transparent such that the see-through area of the first lens 1 is extended on the two lateral sides. When wearing the goggles during work or other activities, therefore, the user A will be able to have a large field of view, without the goggles hindering the work or activities; consequently, the safety of use is ensured. Moreover, the user A no longer has to turn their head to the left or right during work or other activities as is conventionally required when the frame of a pair of goggles narrows the user's field of view on the left and right sides. In other words, the goggle structure of the present invention provides greater convenience of use than their prior art counterparts.

[0048] The above description of an embodiment of the present invention should be able to shed sufficient light on the operation, use, and intended effects of the invention. The disclosed embodiment, however, is only a preferred one of the invention and is not intended to be restrictive of the scope of the invention. Any simple equivalent change or modification based on the appended claims and the contents of this specification should be viewed as falling within the scope of the invention.
