| Abstract: |
The spectacle frame includes a frontal lens support incorporating a nose bridge, a pair of temples, and hinges connecting each temple to an outer end of the lens support. A blind bore or socket is formed in either the lens support or the temple at at least one outer end of the lens support. A sleeve assembly, including an internally threaded sleeve and an externally threaded adjusting rotor member, is inserted in each socket. The adjusting rotor member has an outer end engaging the other of the lens support and the temple. The sleeve has a length less than the depth of the associated socket, and is formed with a flange on its outer end limiting forcing of the sleeve into the socket, under pressure, to a depth in which the flange is flush with the surface of the lens support or temple in which the bore or socket is formed. The adjusting member has a stop at its inner end preventing displacement from the sleeve, and is formed with a notched or knurled operating head particularly configured for operative association with tools for assembling the rotor in the sleeve and inserting the adjusting assembly in the socket. In a modification, the rotor member is threadedly engaged in an internally threaded aperture in a plate portion of a half hinge, the internally threaded aperture being axially aligned with a socket.

What is claimed is:
1. In a spectacle frame of the type including a frontal lens support incorporating a nose bridge, a pair of temples, respective hinges connecting each temple to the respective outer end of the lens support, a socket formed in one of the lens support and the temple, adjacent at least one outer end of the lens support, an internally threaded element axially aligned with each socket, and an externally threaded adjusting number threadedly engaged in each internally threaded element and having an outer and engaging the other of the lens support and the temple at a point spaced outwardly from the axis of the associated hinge, with the internally threaded element having an axial length less than the depth of the associated socket with which it is axially aligned and having an outer end which is substantially flush with the surface of that one, of the lens support and the temple, formed with the associated socket, and with the externally threaded adjusting member being constituted by a threaded rotor having an operating head on its outer end and a threaded stem extending inwardly from the head and threadedly engaged through the associated internally threaded element, and with each internally threaded element and the associated threaded rotor conjointly defining a temple adjusting assembly in which the head of the rotor is engaged with the other of the lens support and temple for adjustment of the angularity of the temple to the lens support by rotation of the associated rotor relative to the associated internally threaded element, and with the head of each rotor having a periphery formed for effecting rotation of the associated rotor by a person wearing the spectacle frame, each rotor having an axial length substantially longer than the threaded length of the associated internally threaded element whereby the rotor has a telescopic relation with the associated internally threaded element: the improvement comprising each rotor, after telescopic assembly into its associated internally threaded element having the inner end of its threaded stem formed with limiting means limiting outward movement of the rotor relative to the associated internally threaded element to a position in which the rotor remains threadedly engaged in the associated threaded element; the head of each rotor limiting inward movement of the rotor, relative to its associated internally threaded element, to a depth less than the depth of the associated socket; each internally threaded element having an area of surface engagement with that one, of the lens support and the temple, having the socket formed therein sufficient to stabilize the internally threaded element to maintain the internally threaded element in accurate axial alignment with the associated socket by resistance to off-axis stresses imposed on the internally threaded element during operation of said adjusting assembly to adjust the angularity of the temple to the lens support; each rotor being movable, by rotation thereof, through an axial distance very substantially greater that the axial extent of the threads of the associated internally threaded element before the rotation is limited by engagement of said limiting means with a portion of the associated internally threaded element spaced axially a substantial distance from the inner end of said socket; the head of each rotor having its outer surface formed with an unthreaded axially extending recess, and also being formed with a notched periphery; and a tool operatively engageable with the rotor head to axially align the rotor with the associated internally threaded element and to thread the rotor into the associated internally threaded element, by rotation thereof, to form said adjusting assembly; said tool being formed with an elongated handle and with an operating end engageable with the outer surface of the head of a rotor; said operating end having a pin extending centrally therefrom for engagement into said unthreaded axially extending recess in the rotor head and with means cooperable with said notches to effect rotation of the associated rotor, when said pin is thus engaged in said recess; whereby said tool may be engaged with a rotor to axially align the rotor with the associated internally threaded element and then to rotate the rotor to thread it through the associated internally threaded element to form said adjusting assembly, after which the inner end of the stem of the associated rotor is formed with said limiting means limiting outward movement of the rotor relative to the associated internally threaded element to maintain the rotor constantly threadedly engaged through the associated internally threaded element; said tool thereafter being operable to have said adjusting assembly mounted thereon, through engagement of said pin into said rotor recess, whereby said adjustment assembly may be accurately guided in accurate axial alignment with the associated socket during assembly of the adjusting assembly with that one, of the lens support and temple, having said socket formed therein.
