The association deals with a plague-laying device the length of the temples of the glasses, in particular of the temples of the so-called hearing glasses * containing a hearing aid

In normal glasses the Längdde ^ Temples _is? which can be different depending on the head shape of the intended spectacle wearer ₉ initially roughly defined during manufacture. Fine adjustment of the eyeglass frame length to the head shape of the eyeglass wearer is then carried out by bending the rear bent temple end; which is possible with the V / arm verformability of the ironing material without particular difficulties.

The exact adaptation of the hearing glasses frames to the head shape of the customer has so far made a great deal of difficulty, as these hollow and box-shaped temples that hold the hearing aid cannot be bent due to their rigid design. This results then _f that these Hörbrillengeräte often are poorly adapted and Srager .verursachen complaints. Sin a "=" wall-free Sits is precisely in these Hörbrillen particularly important because by the "©© weight of eingebau · = th hearing © © in" much stronger pressure won the glasses on reading and ears exerted than normal

An indentation 19 can be seen on the bracket sleeve 11 *, with which the bracket rests on the auricle.

When using such a measuring bracket, a pair of these is screwed to the middle part of the glasses and, after loosening the knurled screws 15, the length can be varied until the correct setting of the glasses is obtained. This correct setting is possible when the recess 19 for the auricle adapts itself completely to the ear and when the middle part of the glasses assumes the prescribed position around the eyes. The optician now screws the two bracket parts tightly against each other by tightening the knurled screw and loosens the bracket at the hinge again the bracket parts can be read off the scale 18, what is sufficient for the patient "to cut the hearing aid bracket to the correct length and cement it together in the correct position"",
