Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
141 words
Spectacles comprising a frame, a set of lenses separate from and connected to the frame, said frame made from an elongated continuous cylindrical element which forms the front frame part to which the set of lenses are connected as well as the side branches which are to be positioned to the sides of the wearer's head, said continuous cylindrical element being capable of being initially rectilinear and bent, at least at certain locations, into a desired shape by the wearer, said certain locations being located at least at the junctions of said side branches with the front part and said certain locations comprising a semi-rigid deformable bellows, such that the frame can be bent at said bellows, by the wearer, into a shape which, because of the semi-rigid deformable characteristic, retains its bent shape while being capable of being subsequently deformed.
Claim 2
Dependent Claim
141 words
Spectacles comprising a frame, a set of lenses separate from and connected to the frame, said frame made from an elongated continuous cylindrical element which forms the front frame part to which the set of lenses are connected as well as the side branches which are to be positioned to the sides of the wearer's head, said continuous cylindrical element being capable of being initially rectilinear and bent, at least at certain locations, into a desired shape by the wearer, said certain locations being located at least at the junctions of said side branches with the front part and said certain locations comprising a semi-rigid deformable bellows, such that the frame can be bent at said bellows, by the wearer, into a shape which, because of the semi-rigid deformable characteristic, retains its bent shape while being capable of being subsequently deformed.
