Definitions

  • This invention relates to an electronic locking device which turns an object into locked or unlocked condition by key input of coded symbols from outside.
  • electronic locks are generally free from such troubles as carrying the key at all times or the possible theft by duplicated pass key, and have higher confidential performance than that of dial keys for safe, and therefore, are used not only for building doors but also for doors of safe and automobiles or suit cases and others.
  • Fig. 1 is a perspective view of a suit case provided with an electronic locking device according to this invention
  • twelve square key buttons 3 shown at the right side of the handle 2 are arranged on the upper side plate 1 H of the suit case 1, which are composed of ten keys ( - ) for code input, one power switch key (s) and one unlocking key (U).
  • the control unit 10 of the micro-computer for memorizing, comparison and computation of key input is provided in the case 1 near the key buttons 3.
  • the manual knobs 4A, 4B for open- shut operation of the suit case are provided at both ends on the upper side plate 1 H, and under locked condition of the suit case, these manual knobs are depressed to the level of the upper side plate 1 H, as shown by the continuous lines, this being achieved by solenoids 8A, 8B controlled by the control unit of the locking device provided inside of the case 1.
  • the manual knobs 4A, 4B are pushed up by several mm as shown by the dotted lines, and then by sliding the knobs in arrow directions (a), (b) respectively, at the same time, the lid 5 of the suit case can be opened.
  • An indicator 6 to show the variable component (Xt) of the code symbols, i.e. the figures that change as time passes, is a digital clock, which indicates a time in hour-minute unit like "PM 12:04" for instance by crystalline liquid letters, and can be adjusted by the digital clock adjusters 7.
  • FIG. 2 is a block diagram to show the circuit configuration of the electronic locking device according to this invention.
  • the power switch (S) among the key buttons 3 is for ON/OFF operation of the power source 9 for the electronic locking device (DC 6V incorporated battery, for example).
  • the control unit 10 of the microcomputer has the control circuit 13, the memory 14, the relational operation circuit 15 and the clock pulse generating circuit 16.
  • the memory 14 not only memorizes the preset coded symbols, but also memorizes the changing indication of the digital clock 6 every moment and renews the memory.
  • the input figure for unlocking is composed of two components: the figure indicated in the digital clock 6 and the figure preset is the memory 14.
  • the indicated figure that changes as time passes is the variable component (Xt) of the input coded symbols.
  • the switch key (S) As the order of operation for locking of the suit case the switch key (S) is turned to ON and the case lid 5 is closed, then the electronic locking device functions to lock the case and the knobs 4A, 4B are depressed as illustrated.
  • AX becomes equal to Xf
  • the coincidence signal (Ss) is sent from the control unit 10 to the small sized loudspeaker 11 in the suit case to issue continuous sound.
  • the operator pushes the unlocking key (U), then the unlocking signal (Su) is given as the output from the control unit 10 to the motor driving control circuit 12.
  • the motor driving control circuit 12 applies the voltage of the power source 9 to the solenoids 8A, 8B for operation, thus the knobs 4A, 4B are released.
  • the manual knobs 4A, 4B are pushed up by several mm above the upper side plate 1 H as described above, and after that, the operator slides the knobs to respective sides, then the suit case opens.
  • a digital counter that counts the clock pulse of.the control unit 10 may also be used.
  • this invention offers a convenient locking device that can maintain confidence of the coded symbols strictly almost permanently because the disadvantage of a conventional electronic locking device in lowered confidential performance due to hand-stain of some specific key buttons used for the code symbol is now solved by the composite code arrangement of the variable figure and the fixed figure making the frequency of use approximately equal to all the key buttons and avoiding hand-stain of any specific buttons completely, and because it can eliminate such trouble as impossible unlocking due to forgotten coded symbols as the fixed intrinsic figure to be memorized can now be a simple one easy to memorize.
