Abstract:
A combination lock with a dial displaying window which is directed to a combination lock with the installation of a dial matching frame placed across all the dials and having at least one window for the users to check the combination numerals or symbols on the dials through the window for unlocking the combination lock. The dial matching frame may be differently constructed to provide the window with the displaying function. A magnification lens may be mounted on the window to further enhance the effectiveness during utilization.
Abstract:
An improved combination lock comprises any type of conventional combination lock having nonnumerical indicia thereon including a plurality of patches of different daylight fluorescent colors for indicating a predetermined combination. Alternatively, nonnumerical indicia on the lock can comprise pictures of different animals, or different geometrical patterns including sets of at least three parallel lines. One implementation comprises a rotatable inner portion inside an outer housing, with sequential positioning of the inner portion with respect to the outer housing serving to unlock the lock. A second implementation includes a plurality of individually rotatable portions, the rotation of which to a predetermined configuration of relative orientations unlocks the lock. Other implementations include electromechanical or electronic combination locks utilizing a keypad and keys with nonnumerical combination indicia thereon comprising colors, either daylight fluorescent or ordinary, pictures of different animals, or different geometrical patterns including sets of at least three parallel lines.
Abstract:
An improved combination lock includes a plurality of patches of different daylight fluorescent colors with or without additional nonnumerical indicia, for indicating a predetermined combination. Alternatively, the patches can all be of the same fluorescent color and used as a contrasting background for the additional nonnumerical indicia. The additional nonnumerical indicia can comprise different geometrical patterns including sets of at least three parallel lines, or pictures of different animals. The indicia are preferably made larger than is conventional.
Abstract:
A locking apparatus to prevent unauthorized unlocking movement between a first member and a second member, a labyrinth employed between the members, the labyrinth requiring a known combination by an authorized person to produce the desired unlocking movement.
