Frame for spectacles with magnifying lenses
A frame for spectacles with magnifying lenses includes a magnifying eyepiece for mounting on each lens. The frame includes: a front mount including, for each lens, a respective slot extending between a central region of the nose support mount and an opposite lateral region of the mount, each slot being configured to receive a portion of a respective lens-carrying support, partially surrounding a peripheral edge portion of the lens, and fixing means for fixing the lens-carrying support which is received in the respective slot to the front mount. The lens-carrying support is received in the corresponding slot with a coupling play transverse to the front mount, and the fixing means are configured to fix each lens-carrying support to the front mount in a preselected relative positioning which is allowed by the coupling play, making the orientation of each lens adjustable with respect to the front mount.
1 . A frame for spectacles with magnifying lenses, of the type in which there is provision on each lens for a magnifying eyepiece to be mounted, said frame comprising:
a front mount including, for each lens, a respective slot which extends at least at an eyebrow arch zone of the frame, between a central region of a nose support mount and an opposite lateral region of the front mount for articulating a respective arm to the frame, each slot being configured to receive at least one portion of a respective lens-carrying support which can support the lens by at least partially surrounding a peripheral edge portion of the lens,
fixing means for fixing the lens-carrying support which is received in the respective slot to the front mount, wherein the lens-carrying support is received in the corresponding slot with a coupling play transverse to the front mount and said fixing means are configured to fix each lens-carrying support to the front mount in a preselected relative positioning which is allowed by the coupling play so as to make the orientation of each lens adjustable with respect to the front mount, wherein said fixing means comprise at least one fixing screw which is configured to engage with a screwing action with a threaded hole which is provided in the lens-carrying support, passing through a through-opening which is slotted and formed in the front mount at the corresponding slot so that the screw is engaged in the slotted opening with relative freedom to slide between opposite ends of said slotted opening in order to be gripped in the preselected relative positioning corresponding to the desired orientation of the lens with respect to the mount.
2 . The frame for spectacles according to claim 1 , wherein, for each lens, the coupling play inside the corresponding slot increases from the central region of the front mount in a direction of the lateral region and said fixing means comprise a fixing screw which is positioned at the lateral region of the front mount.
3 . The frame for spectacles according to claim 1 , wherein, for each lens, the coupling play inside the corresponding slot is increasing from the lateral region of the front mount in the direction of the central region and said fixing means comprise a fixing screw which is positioned at the central region of the front mount.
4 . The frame for spectacles according to claim 1 , wherein, for each lens, said fixing means comprise a pair of fixing screws which are arranged at the lateral region and the central region of the front mount, respectively.
5 . The frame for spectacles according to claim 1 , wherein said lens-carrying support is made from metal material.
6 . The frame for spectacles according to claim 1 , wherein said lens-carrying support extends in a frame-like manner, with a closed-contour profile, surrounding an entire peripheral edge of the lens.
7 . A frame for spectacles with magnifying lenses, of the type in which there is provision on each lens for a magnifying eyepiece to be mounted, said frame comprising:
a front mount including, for each lens, a respective slot which extends at least at an eyebrow arch zone of the frame, between a central region of a nose support mount and an opposite lateral region of the front mount for articulating a respective arm to the frame, each slot being configured to receive at least one portion of a respective lens-carrying support which can support the lens by at least partially surrounding a peripheral edge portion of the lens,
fixing means for fixing the lens-carrying support which is received in the respective slot to the front mount, wherein the lens-carrying support is received in the corresponding slot with a coupling play transverse to the front mount and said fixing means are configured to fix each lens-carrying support to the front mount in a preselected relative positioning which is allowed by the coupling play so as to make the orientation of each lens adjustable with respect to the front mount, wherein each slot extends between a pair of opposite lateral walls which are connected to a bottom wall and the lens-carrying support can be fixed in the slot in a plurality of relative positions between a first and a second end position in which the lens-carrying support is in abutment against the one and against the other of the opposite lateral walls, respectively.
8 . The frame for spectacles according to claim 7 , wherein the slot is configured to have a coupling play which is substantially zero at one of the longitudinal ends thereof and a maximum coupling play at the other of the longitudinal ends, said coupling play being increasing from one end in the direction of the other end so that the lens-carrying support can rotate about the end of the slot having substantially zero coupling play between said first and second position.
