Title: Tubular frame lock mechanism - has slide-operated lever working in curved slot in hinging bolt
IPC: E05B63/00
Filed: 1990-06-18
Abstract: The lock for a tubular frame has a hinging bolt (9) passing through the upright (2).  It has a slide (3) engaging at one end with the tongue of a cylinder lock (4,5) and at the other with a bolt, so as to swing the latter between the retracted position parallel to the upright and the extended one at right angles to it. A lever (13) is mounted in the housing at the bolt end of the slide, which moves parallel to the upright, and on a pivot pin (5) parallel to that (10) of the bolt.  Through this a pin (15) fixed to the slide passes at a point clear of its spindle.  Parallel to the latter at the other end of the lever is a guide pin (16).  This works in a curved slot (17), open at the end, in the bolt, extending from the bolt pivot pin through a quarter-circle.  The lever and bolt swing in opposite directions.  Seen in the locking direction, the end of slot extends in the radial direction.  Both when open and locked, the radii of the circles described by the lever and bolt include an angle of 90 deg. USE/ADVANTAGE - The bolt of the lock cannot be swung free without special tools.
