Abstract
This watertight lens assembly structure provides panoramic-viewing for a diving mask without having the lenses glued together. The lenses (3), each have at least one frontal lens (31) and at least one side lens (32) attached to, via a layer of elastic gasket medium, either one or both surfaces of the contacting edges (3111, 321) of the frontal and side lenses. A lens assembly ring presses against the frontal lens and side lens simultaneously, forcing compression against the elastic gasket medium at the contacting edges of the two lenses and securing both lenses to the mask frame. The result is a watertight seal, achieved without adhesives, at the contacting edges of the front and side lenses. The lens may define a single window and have left and right lenses, with a gasket in between (figure 6). The lens assembly ring may be made of two parts with engageable protruding tabs.

(a) Field of the Invention
This invention improves the assemble process of a di\ ing mask filth front lens and side lens, and also enables easier replacement of a broken or scratched lens or e\en optical-correction lens. This process will reduce costs for storage space.
packaging size and transporting of assembled lenses during production
(b) Description of the Prior Art
A diverts mask may include one or more lenses. More recently lenses on each side of the single- or double-frontal-lens mask has e been incorporated to enhance the diverts peripheral vision, thus creating a panoramic aliening ofthe surrounding en\ ironrnent. In the prior art, to achieve this viewing ads antage and \\atertight seal at the lens joint, other manufacturers hate used a permanent adhesive to bond the side and frontal lenses together Such conventional panoramic-).\ die ing masks are populamn the market et gluing, the lenses toetller has some distinct disa:ivanta:,.s from the manufacturer to the consumer (or end user) I For the end user, the replacement of a broken scratched, or prescribed optical-correction lens cannot be done \\,t',.out causing permanent damage-- perhaps even rendering the mask non-water-tight--to the bonded edges of the assembled lenses.
For the manufacturer, high costs can be associated with the pre-bonding of the front and side lenses resulting in a costly three-dimensional shape lens set-up (usually as 1, or U shapes) necessary before the lenses can be assembled to the mask frame. The curing time of the adhesive, often many hours, can also be costly. Expensive high-precision equipment is needed during the bonding process to ensure the quality of the three- dimensional bonding shape of the lenses and the,-atertight inte,rity of the adhesive bond. And the increased bulk of fixtures for the bonded lenses raise storage space and packaging size in prod. Strong These high manufacturing costs are inevitably passed to the consumer.
The objective of this invention is to provide the manufacturer and the end user a more efficient method of assembling panoramic iewin;, diving masks and also to provide a panoramic ie,ving div,mg mask with easily removable Icnses.
SI:5II\IARN (OF THE INVENTION This novel panoramic-\ few diving mask provides a non-glued, completers watertight and removable self-sealing lens assembly (with at least one frontal lens and at least one side lens) in which a layer of elastic gasket medium is attached, or applied, to either one or both surfaces of the contacting edges of the frontal and side lenses. The lens assembly ring is pressed against the frontal lens and the side lens simultaneously, creating compression against the elastic gasket medium and securing the frontal and side lenses to the mask frame for a water-tight seal within the mask NN ithout the application of an adhesive to connect the front and side lenses together at the lens contacting edges. With this non-glued, yet watertight and removable self-sealing lens assembly, individual users can easily replace a lens that is broken. scratched or corrected for near- or far-sighted vision. This improved lens assembly process results in reduced storage space, reduced packaging sizes and reduced costs of transportation of the assembled lenses during mass production.
To enable further understanding of the stated objectives and the technological methods of the invention herein, a brief description of the drawings belo\ is followed by a detailed description of the preferred embodiments as set forth below.

DET.41LED DESCRIPTION OF THE DRAWINGS
AND THE PREFFERED E)lBODOIENTS Referrmg to l;IG I and 2. The present invention Is a panoramc-vrew dome mask comprising a hard plastic frame body 1, a soft silicone skirt 2, a head strap 10, two lens assembly 3, and two lens assembly rmgs 4, wherein a soft silicone skirt 2 Is i located mside the frame body 1, a frontal lens 31 and a side lens 32 of dual-window | lens assembly 3 Is located Inside the lens frame opening 21, and the lens assembly I rmg 4 Is located around each lens assembly 3.
The lens assembly 3 is formed by assembling the frontal lens 31 to the side lens 32 while a layer of elastic gasket medium A, Is attached to or applied to either one or both surfaces of the contacting edges 311 and 321 of the frontal lens 31 and side lens 32, respectively The side lens 32 is then inlaid into the frame groove 11, which can be molded-m or an assembled body, formed on the mner side of the lens frame opening 21 The frontal lens 31 is placed on the front side of the lens frame opening 21 to allow the contacting edge 311 of the frontal lens 31 to come in contact with the contacting edge 3 21 of the side lens 32 The lens assembly rmg 4 Is pressed against the frontal lens 31 and side lens 32 simultaneously to force the contacting edges of 3 1 1 and 321 to press tightly together meanwhile compressing the elastic gasket medium to create a \\atertght seal of this non-glued and removable self-sealing lens assembly of a panoramc-vew dung mask.
Referring to FIG 3 I to 3 3 A non-glued, water-tight and removable selfseahug lens assembly 3 can be done by applying or attaching a layer of elastic gasket medium A to either one or both surfaces of the contacting edges 311 and 321 of the front lens 31 and the side lens 32, respectively.
Referring to FIG. 4, the lens assembly ring 4' comprises a front partial ring 41 and side partial ring 42, upon which protruding tabs 411 and 491 are respectively located. The dual-window lens assembly 3 comprises the frontal lens 31 and the side lens 32 with a layer of elastic gasket medium A applied to or attached to either one or both surfaces of the contacting edges 311 and 371 of the frontal lens 31 and side lens 32, respectively. The side lens 32 is placed into the lateral side of the lens frame opening 21 then the side partial ring 42 presses against the side lens 32 while engaging the protruding tab 421 of the side partial ring 42 to both slots 13 located on the surface of the upper and lower section of the mask frame body 1, thereby stationing side lens 32 in the lens frame opening 21. The frontal lens 31 is then placed into the front side of the lens frame opening 21 and is pressed against by the front partial ring 41 while inserting the protruding tab 411 of the front partial ring 41 into both slots 12 located on the inner surface of the upper and lower section of the mask frame body 1, to force the contacting edges of 311 and 321 to press tightly together meanwhile compressing the elastic gasket medium in between to create a watertight seal of this non-glued, removable self-sealing lens assembly of a panoramic-view diving mask.
Referring to FIG. S 6, the present invention applies to the diving mask having a single-window lens assembly 5. A self sealing water-tight, single-window lens assembly S is assembled with the leR-half lens 51 and the right-half lens 52 having a layer of elastic gasket medium B attached to or applied to one or both surfaces of the contacting edges 511 and 521 of the left-half lens 51 and right-half lens 52, respectively. With the non-glued, yet watertight and removable self-sealing lens assembly S described herein, individual users can easily replace a lens that is broken, scratched or corrected for near- or far-sighted vision.
The embodiments described herein clearly demonstrate the improved method of the lens assembly of a panoramic-view diving mask without the application of adhesive, and void of permanent bonding, to the lenses. This non-glued, watertight and removable self-sealing lens assembly structure will allow the retrofitting of, or replacement of, lenses that are broken or scratched, or needing vision correction without affecting the watertight integrity of the lens assembly. Moreover, the benefit to improvement in productivity and lowering of the costs in manufacturing can be clearly seen. Various modifications of this invention may be contemplated and can be resorted to without departing from the spirit and scope of this invention as defined by the following claims.
