Abstract
A pad system for supporting a spectacle frame on the bridge of the nose of the wearer includes a pad arm fastened to the spectacle frame in the area of the root of the nose of the wearer. The pad arm has a generally rectangular cross section at the outer end thereof for fastening the pad which has a rectangular blind hole for receiving the outer end of the pad arm. The blind hole is configured such that the longitudinal axes of the cross sections of the blind hole and the pad conjointly define an acute angle. Additionally, it is advantageous to place the blind hole outside of the center axis of the pad. By pushing the pad onto the pad arm in different positions, a spectacle frame with rigid pad arms can easily be adapted to the anatomical actualities of different facial shapes.

A pad system for a spectacle frame comprising:
- a pad arm attached to the spectacle frame in the region of the root of the nose of the wearer;
- a pad having a longitudinal pad axis and having a pad cross section transverse to said axis, said pad cross section having a cross-sectional longitudinal pad axis, said pad having a blind hole formed therein so as to be offset from said longitudinal pad axis;
- said hole having a hole cross section of non-circular configuration and having a cross-sectional longitudinal hole axis corresponding to said hole cross section;
- said cross-sectional longitudinal pad axis and said cross-sectional longitudinal hole axis conjointly defining an acute angle .alpha.;
- and,
- said pad arm having an end portion with a non-circular arm cross section corresponding to the non-circular hole cross section so as to permit said pad to be pushed onto said pad arm for engaging the same therewith while preventing a rotation of said pad relative to said pad arm.
A spectacle frame comprising:
- two lens holders;
- bridge means interconnecting said lens holders;
- a pad system for seating the spectacle frame on the nose of a wearer thereof;
- said pad system including:
- two pad arms connected to corresponding ones of said lens holders in the region for the root of the nose of the wearer;
- and, two pads corresponding to respective ones of said pad arms;
- each of said pads having a longitudinal pad axis and having a pad cross section transverse to said axis, said and cross section having a cross-sectional longitudinal pad axis, the pad having a blind hole formed therein so as to be offset from said longitudinal pad axis;
- said hole having a hole cross section of non-circular configuration and having a cross-sectional longitudinal hole axis corresponding to said hole cross section;
- said cross-sectional longitudinal pad axis and said cross-sectional longitudinal hole axis conjointly defining an acute angle .alpha.;
- and,
- each of said pad arms having an end portion with a non-circular arm cross section corresponding to the non-circular hole cross section so as to permit said pad to be pushed onto said pad arm for engaging the same therewith while preventing a rotation of said pad relative to said pad arm.
