Title: Bramah lock with sliding rotary grooved box in barrel housing - has narrow keyhole preventing forcing of box rotation by thick blade insert
IPC: E05B27/08
Filed: 1976-07-07
Abstract: The bramah lock with a sliding rotary grooved box (11) has a keyhole (20) of a narrow slit shape and deploys a key (12) with a specially contoured radial blade (21) on the end of a slender shaft (22). The arrangement obviates lock violation whereby a robust blade inserted in prior key holes could be used to shear the box rotation-block. The grooved box is contained in a barrel housing (10), and successively slides and rotates in the barrel under key authorisation. The box rotation-lock operates when the grooved box is in the forward repose position, and comprises a housing lug (16), which engages a notch (17) in the front wall (18) of the box. The key hole may locate axially vertical in the front wall of the barrel, and may inc. a central circular enlargement which accommodates the key shaft (22).
