"Pe the hinge for glasses to press over the temple ^ ADDITIONAL ζ. Ρ 21 26 898.4)

The invention relates to a further development of the lower hinge for glasses. to push the temple over the stop position to the resilient contact on the head of the wearer consisting of hinged brackets 1- and middle part hinge according to patent .... ... (P 21 26 898.4).

The main godfather, t concerns such a pe the hinge, at which the bracket hinge part with its extended end (spring receiving part) runs in a receiving box at the end of the bracket and an inserted spring for the Eückioliing from the overpressure position Formal disclosure ensures. ·

It is now the task of further training with precise guidance of the

To achieve a simplification in the manufacture of the spring mount and to be able to manufacture the spring hinge as a structural unit independently of the spectacle frame. This is indicated by. The inventive Pe the hinge of the aforementioned type in that a square profile tube with longitudinal grooves on both sides is used as a receiving and guide box for insertion into a Kihrungsaufnahme the · eyeglass temple, the same front side is cut out from the hinge hinge part for the exit of the hinge eyes and at the end with a terminating piece , which extends into the open end of the profile tube, is closed.

Subject a special idea of the invention is in the recording and! guide box at the front below the hinge eye a key block can be inserted and screwed as a spring stop, which extends with guide strips on both sides in side slots on the mounting and guide box. The locking screw is sufficient here for the locking block when screwing into a bottom opening of the square profile tube by means of a pin and thus closes the spring hinge as a structural unit. When screwing in further The locking screw engages in the spring hinge inserted into the temple into a hole in the bracket guide or bracket insert and thus defines the built-in spring hinge.

the hinge eye 3 let in. At the temple end 4, the receiving and guide ^{box 5 is inserted into E 1} omn. Of a square profile tube with longitudinal grooves 6 on both sides in the guide seat of the temple over the inserted temple insert 7. In the receiving and guide box 5, the bracket hinge part 8 runs, which on the one hand has eyes 9 for connection to the hinge eye 3 by means of a hinge screw 10 with nut 10a and on the other hand extends into the guide box 5 by means of an extended end, which serves as a spring holder 11. The inserted spring 12, here a helical spring, ensures the return from the overpressure position B to normal position A; this (12) is at the end 13 of the spring receptacle 11 as well as on the closing block 14-.

The receiving and guide box 5 in the form of a square profile tube is cut-out at the front at 15 to the exit of the hinge eyes 9 and at the end by means of an end piece 16, which extends into the open end of the profile tube, closed. At the end piece 16 find the longitudinal grooves 6 of the profile tube, as can be seen, its circumferential continuation 6a.

The locking block 14, which can be pushed in and screwed in, extends with guide strips I7 on both sides in side slots 18 on the receiving

and guide box 5 · 'The locking screw 19 for the lock block 14 is sufficient, as can be seen, when screwing by means of a pin into the bottom opening 21 on the Tierkant profile tube 5 and closes so that the spring hinge as a structural unit, while with further screwing in after the spring hinge pushed into the temple the locking screw 19 into the bore 22 by means of a pin 20 the bracket guide or insert 7 engages and thus fixes the built-in spring hinge. The guide rails on both sides 17 serve on the closing block 14, as can be seen from Fig. 5, at the same time as an extension stop 23 for the spring mount 11 the shoulder .24 of the bracket hinge part and thus prevents. overpressing the spring 12.
