Description

Description:

The invention relates to a further development of the combination glasses according to patent .. .. ... (H 562.7).

The combination glasses with the edge of the lens are characterized by any steered glasses temples according to the main patent in that at the free end the same preferably on both sides Closure parts are provided which can be pulled out, which can be worn when glasses are put on serve as sports glasses to connect to the back of the head.

The task of the invention after the development is now for this Combination glasses to simplify manufacturing and both the attachment end the elastic at the articulation end of the temple as well as the pull-out end on the free To secure Büyelende in their functions.

This task is carried out with the Kumbinatiünsbrille after further training yelöst thereby that the temples when made of plastic to accommodate a Rubber toyes each take up a flexible tube, especially a metal hose tube, which beyinnend at the articulation end at the right end to the exit of the locking parts for the pull-out elastic ends. This allows next to the union the production by overmoulding this metal tube also the 5 later adaptation can be realized by the optician to the spectacle wearer without complications.

in particular, the flexible metal hose tube can be used in the case of temples made of plastic lie in a groove of the bracket insert and when manufacturing the plastic bracket with the Bracket insert inserted into the plastic bracket or encapsulated with this.

Further details of the invention after the formation of the pelvis are then on the basis of a preferred embodiment shown in the drawing and explained below and specifically show: 'i g. 1 and 2 show the general view of such Eyeglass temple from the inside with articulated end and the end view of the same from the outside Closure part and F 1 q. j and 4 the sectional view through a plastic bracket part at line III-III and through a closure part according to line IV-IV in an enlarged view.

As can be seen from the drawing, there is the eyeglass temple from the plastic bracket part 31 with metal end 32 and Urille hinge part 33 for Linkage to the eyeglass frame, the Büyeleinlage 34 at the metal end 32 being the flexible Metal hose tube 35 receives in a groove 36. The metal end 32 has the Beginning of the groove 36 of the bracket insert 34 for the metal hose tube 35 for receiving of the elastic band 37. This elastic band 31 is here at the metal end 32 by means of a knot 38 set between the side jaws 39. The elastic band is at the free end of the Büyel 37 encapsulated with a plastic plate 40, which is partially in an end pocket 41 retracts and has a transverse groove 42 with barbs 43 and so the mutual When wearing glasses, hang it behind the wearer's head to secure it Sport and dyl.

serves. The end hooks in the shape of plastic plates 40 with a transverse groove 42 and barbs 43 are designed here so that they have the same shape on both sides and thus only one injection mold is required for this.
