Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
210 words
A readily disengageable locking assembly for the lenses of eyeglasses, swimming goggles, diving masks and the like, comprising: a lightweight, relatively rigid, plastic body having two rearwardly-disposed, countersunk seats having planar bottoms, lying in the same plane, each of which is configured to accommodate a packing and a lens, and each of which has a forwardly-disposed, oppositely-arranged, outwardly-flaring, U-shaped rim with the ends of the rim directed toward the respective lateral ends of said body, said rims each having a groove formed therein along the inner periphery thereof, said body also having at each lateral end thereof a casing having an elongated slit extending therethrough, perpendicular to the planar bottoms of said seats; a packing disengageably received within each of said countersunk seats; a lens disengageably received within each of said packed countersunk seats; a frame, disengageably and slidably received within said groove of each of said rims, for maintaining said lenses and packing in a correct position with respect to said seats, said frames each having a corresponding slit formed therein which, when fully inserted in said groove of said rims, is aligned with said slit of said casings; and a disengageable locking member insertable within said slits of said frames and casing, to effect locking of said assembly.
Claim 2
Dependent Claim
210 words
A readily disengageable locking assembly for the lenses of eyeglasses, swimming goggles, diving masks and the like, comprising: a lightweight, relatively rigid, plastic body having two rearwardly-disposed, countersunk seats having planar bottoms, lying in the same plane, each of which is configured to accommodate a packing and a lens, and each of which has a forwardly-disposed, oppositely-arranged, outwardly-flaring, U-shaped rim with the ends of the rim directed toward the respective lateral ends of said body, said rims each having a groove formed therein along the inner periphery thereof, said body also having at each lateral end thereof a casing having an elongated slit extending therethrough, perpendicular to the planar bottoms of said seats; a packing disengageably received within each of said countersunk seats; a lens disengageably received within each of said packed countersunk seats; a frame, disengageably and slidably received within said groove of each of said rims, for maintaining said lenses and packing in a correct position with respect to said seats, said frames each having a corresponding slit formed therein which, when fully inserted in said groove of said rims, is aligned with said slit of said casings; and a disengageable locking member insertable within said slits of said frames and casing, to effect locking of said assembly.
Claim 3
Dependent Claim
72 words
The locking assembly of claim 1, wherein said locking members comprise a generally flat, L-shaped member, having a relatively short upper leg which serves as an abutment against said frame, and a relatively longer lower leg, which is insertable within said slits of said frame and casings and which have formed therein two slots for hooked connection with an article-fixing strap, which connection also prevents any undesired disengagement of the locking assembly.
Claim 4
Dependent Claim
17 words
The locking assembly of claim 1, wherein said frames and locking members are fabricated from stainless steel.
