Abstract
In a coupling construction of a frame of spectacles 2 of light alloy a coupling holder 4 of even metal with a joint for a hinging mechanism to connect the bows of the spectacles thereto is screwed to cut seat members 1,3 projecting integrally from cut ends of the frame of spectacles 2. Two screws 5,6 being screwed into each other are provided to secure the coupling holder 4 to the seat members 1,3. With the screw 5 of a more durable metal than light metal the coupling holder 4 is fastened to one of the seat members 1,3. To secure the other seat member 1,3 to the coupling holder 4 as well the screw 6 is passed through that seat member 1,3 and inserted into a longitudinally screwed hole in the screw 5. According to this a secure screw joint between the coupling holder 4 and the seat members 1,3 is achieved and the joint can be opened and reclosed unlimitedly without failure due to weak light alloy threads.
