Abstract

A groove of semi-circular section is milled in the end of the screw shaft, in its circumference parallel with the centreline of the screw. Two matching grooves also of semi-circular cross section are machined across the thread in the nut. The two grooves in the nut are loacted diametrically opposite one another. The nut is tightened on the screw until one of the grooves in the nut is in line with the groove in the screw. A locking pin is then fitted in the hole which is formed by the two semi-circular grooves.

B ei der Herstellung unlösbarer Veibindungan bei denen bislang genietet wurde,wäre eine Stiftgesicherte-Schraubverbindung insoweit praktikabler,als diese erhsbli@h schneller und aufwandtsloser hergestellt werden kann.When creating permanent connections where previously riveted a pin-secured screw connection would be more practicable than this erhsbli @ h can be produced faster and with less effort.

Zur H er stellung unlösbarer Schraubverbindungen mit " Stiftsicherung System Hans meier " wird in das Muttergewinde undin den Schraubeschaft jeweils eine bzw. zwei ( Muttergewinde) @ussparungen eingebracht (sägen,fräßen usw.).For making permanent screw connections with "pin lock" System Hans Meier "becomes one in the nut thread and one in the screw shaft or two (female thread) recesses are made (sawing, milling, etc.).

Werden nun beim Anziehen der Schraubenmutter die Aussparungen von Schraubenschaft und Mutter einander gegenübergestellt entsteht ein zylinderförmiger Hohlraum.When the screw nut is tightened, the recesses of When the screw shank and nut are juxtaposed, a cylindrical shape is created Cavity.

Indiesen Hohlraum wird mit dem Hammer ein Stahlstift eingeschlagen und, aufgestaucht Eine solcherart gesicherte Schraubverbindung ist unlösbar.A steel pin is driven into this cavity with a hammer and, upset A screw connection secured in this way cannot be released.
