Abstract (en)
[origin: DE19614761C1] The invention relates to a locking block-screw connection secured against loosening and intended for spectacles with frame mounts. The aim was to create a locking block-screw connection which, with a novel design of connection zone, would create an elastic protection against loosening of the screw. According to the invention, the bore in the locking block is provided with an annular taper at the thread runout with a thread-side angle beta which with the angle alpha forms the angle sigma corresponding to the tapering point. The screw has a novel pin extension; the pin is provided with an annular groove into which the taper of the locking block engages elastically when the screw is screwed in.
