<p>A keyless lock has a resident code disc having code pegs (284) defining a resident binary code. An input code disc (248) has slider pins (272) each movable between two positions corresponding with binary values 0 and 1 of the corresponding input code bit. Opening of the lock requires the two discs to be moved together and this is only possible if every slider pin (272) has been placed in the correct position so as not to foul the associated resident code peg (284). The input code is entered by repeated movement of a handle (260) from a neutral position to either of two offset positions corresponding respectively with bit values 0 and 1 in the input code.</p> |
