<p>Some improvements are disclosed in mechanical programmers by means of which the forward or backward movement of a rod or rods is achieved which can be used for locks or activating other systems by means of their movement, further enabling more than one combination being able to activate the rod (several uses of the same object) or for allowing the movement of the said rods it is necessary to use more than one combination and including being able to detect which was the last one that allowed the movement by adding other subsystems, all this by means of a toothed rack system or cogwheels that can be driven by pushing, rotation or sliding.</p> |
