Eyeglasses having readily removable lenses

Claim 2

An eyeglass comprising at least one lens means having a lens viewing portion with an appendage of a first chosen dimension extending from a peripheral zone of said viewing portion and support means for said lens means including a first lens carrier having a slot of a second chosen dimension into which said appendage is disposed, said appendage having a longitudinal detent groove therein, said first lens carrier including deflectable resilient retaining means confined within said carrier for detachably holding said appendage in fixed position in said slot, said retaining means including an elongated detent spring protruding into said slot and arranged to deflectively retract upon disposition of said appendage in said slot such that said appendage is detentively retained in said slot by resilient expansion of said detent spring into said detent groove in said appendage.

Claim 3

An eyeglass as claimed in claim 1 wherein that a second lens means, having a second appendage of said first chosen dimension can be interchangeably disposed in said lens carrier slot with said one lens means.

Claim 4

An eyeglass as claimed in claim 2 wherein said carrier includes a curved V-shaped bridge portion having oppositely disposed depending legs and said slots are formed in the legs of said bridge portion for insertion of said appendage.

Claim 5

An eyeglass as claimed in claim 3, said support means further including means for maintaining said lens carrier in viewing position, said maintaining means comprising a temple piece having one end secured to said lens means and an opposite free end, said one end of said temple piece including a slot, said lens means including a second appendage in engagement with the slot of said temple piece.

Claim 6

An eyeglass as claimed in claim 1 wherein a second lens carrier, of differing size and shape than said first lens carrier but having a second slot of said second chosen dimension, is interchangeable with said first lens carrier for accommodating the appendage of said first lens means in the slot of said second lens carrier.

Claim 7

An eyeglass as claimed in claim 5 wherein, said carrier includes a curved V-shaped bridge portion and a pair of oppositely disposed lens support arms formed at the mouth of said ''''V'''' and extending away from said ''''V'''' in substantially opposite directions, said slots being formed in said oppositely disposed lens support arm.

Claim 8

An eyeglass as claimed in claim 1 wherein said spring is relatively movable with respect to said slot, disposition of said appendage into said slot causing said spring to retract, expansion of said spring against said detent groove retaining said appendage in said slot.

Claim 9

An eyeglass comprising at least one lens means having a lens viewing portion with an appendage of a first dimension extending from a peripheral zone of said viewing portion and support means for said lens means including a first lens carrier having a slot of a second chosen dimension into which said appendage is disposed, said retaining means including oppositely disposed side portions extending from said peripheral zone, at least one of said side portions having a detent notch therein, said first lens carrier including deflectable resilient retaining means confined within said carrier for detachably holding said appendage in fixed position in said slot, said retaining means including a detent nipple biased by spring Means in said lens carrier and protruding into said slot and arranged to deflectively retract upon disposition of said appendage in said slot such that said appendage is detentively retained in said slot by resilient expansion of said detent nipple into said detent notch in said appendage.

Claim 10

An eyeglass comprising at least one lens means having a lens viewing portion with an appendage of a first dimension extending from a peripheral zone of said viewing portion and support means for said lens means including a first lens carrier having a slot of a second chosen dimension into which said appendage is disposed, said retaining means including oppositely disposed side portions extending from said peripheral zone, at least one of said side portions having a detent notch therein, said first lens carrier including deflectable resilient retaining means confined within said carrier for detachably holding said appendage in fixed position in said slot, said retaining means including a detent nipple biased by spring Means in said lens carrier and protruding into said slot and arranged to deflectively retract upon disposition of said appendage in said slot such that said appendage is detentively retained in said slot by resilient expansion of said detent nipple into said detent notch in said appendage.

Claim 11

An eyeglass as claimed in claim 8 wherein a second lens means, having a second appendage of said first chosen dimension can be interchangeably disposed in said lens carrier slot with said one lens means.

Claim 12

An eyeglass as claimed in claim 9 wherein said carrier includes a curved V-shaped bridge portion having oppositely disposed depending legs and said slots are formed in the legs of said bridge portion for insertion of said appendage.

Claim 13

An eyeglass as claimed in claim 10, said support means further including means for maintaining said lens carrier in viewing position, said maintaining means comprising a temple piece having one end secured to said lens means and an opposite free end.

Claim 14

An eyeglass as claimed in claim 8 wherein a second lens carrier, of differing size and shape than said first lens carrier but having a second slot of said second chosen dimension, is interchangeable with said first lens carrier for accommodating the appendage of said first lens means in the slot of said second lens carrier.

Claim 15

An eyeglass as claimed in claim 12 wherein said carrier includes a curved V-shaped bridge portion and a pair of oppositely disposed lens support arms formed at the mouth of said ''''V'''' and extending away from said ''''V'''' in substantially opposite directions, said slots being formed in said oppositely disposed lens support arms.

Claim 16

An eyeglass as claimed in claim 8 wherein said detent nipple is relatively movable with respect to said slot and urged into said slot by a spring such that disposition of said appendage in said slot causes said nipple to retract, expansion of said spring urging said nipple into engagement with said detent notch to maintain said appendage in said slot.
