Definitions

  • the application provides a structure that enables an electronic lock to function not only as an elec­tronic lock necessary to use a coded key card but also as a common lock with the electronic part temporarily kept invalid.
  • the main feature of the structure is the function described in Item 2, and it means this lock can function as a common lock with the electronic part temporarily stopped.
  • the structure includes only one dead bolt, so it has a rather weak protective security against burglary because unlawful thieves can break the lock by sawing the dead bolt or prying open the gap between the door and the door frame with a hard spanner. Therefore, this applicant has newly devised a new latch control structure and a latch for electronic locks in order to reinforce its security against burglary.
  • a latch control structure and a latch for an electronic lock comprises an outside cover 1 and an outside knob 11, said outside knob 11 turning a square shaft 13.
  • the front end of said square shaft 13 is fixed with an engaging disc 131.
  • Said outside cover 1 is provided with a sensor 15 which gives out a signal to a magnetic coil 16 to work only when a correct coded key card is inserted in; when said magnetic coil works, a blocking plate 45 is to be freed of its control over a moving base 44 so that said base 44 can engage with said engaging disc 131 of said square shaft 13.
  • said outside knob 11 can be turned to pull in the dead bolts 65, 66 of a latch 6.
  • This invention also comprises an inside cover 2 and an inside knob 23, said knob 23 turning a square shaft 42.
  • Said square shaft 42 can directly turn an engaging base 46, which then turns a moving tube 37. Then said moving tube 37 can pull in the dead bolts 65, 66.
  • Said inside cover 2 is provided with a turning button 24, whose turning movement can make the upper dead bolt 66 of the latch 6 automatically extend out for reinforcing the preventing function of this lock against burglary.
  • This new latch control structure and the latch for electronic locks comprises an outside cover 1, an inside cover 2, a basic plate 3, moving parts 4, a security means 5, a latch 6 as its main parts as shown in Figure 1.

So said bolt 66 becomes sticking in the upper dead bolt hole 6102 of the limiting board 610 of the door frame, and this is an reinforced locking function available for a person inside the door.
  • the arm 6364 of the sticking plate 636 still keeps horizontal as the U-shaped base 692 of said bolt 69 is pressed by the spring 696, the protrusion 6363 still sticking in the upper notch 665 of said bolt 66 so that said bolt 66 is impossible to extend out of the holes 6112, 6122.
  • the backward movement of said bolt 69 compresses at first the spring 695 to delay the U-shaped base 692 in pressing the sticking plate 636 so that the turning movement of said plate 636 takes place later than said bolt 66 touches the restricting board 610 or when said bolt 66 has entered the hole 6102 of said board 610.
  • the turning of said plate 636 separates the protrusion 6363 from the upper notch 665 of said bolt 66, said bolt 66, receiving no hampering force, extending out of said holes 6112, 6122 pulled by the spring 661.
  • said bolt 66 sticks in the hole 6102 of said board 610, and this is an automatic reinforced locking function available in going out of the door.
  • said bolt 66 pulls outward simultaneously the connecting plate 632 which in order forces the turning wheel 63 to revolve, and then the edge 6302 of said wheel 63 comes to touch the arm 671 of the moving plate 67.
  • the moving tube 37 can force the moving tube 64 to revolve as shown in Figure 17. Then one end edge of the fan-­shaped plate 643 of said tube 64 can press the hook 652 of said bolt 65 so that said bolt 65 is to be pulled inside the frame plate 61.
  • the long upper straight edge of the oval plate 644 presses the bottom edge 674 of the moving plate 67 at the same time so that said plate 67 moves upward, the arm 671 touching the edge 6302 of the turning wheel 63 and the stopping edge 6312 of the control wheel 631. Therefore, the upward movement of said plate 67 makes said wheel 63 and said wheel 631 both revolve back to their original non-revolving positions; the revolving of said wheel 63 can pull said bolt 66 into the frame plate 61 and that of said wheel 631 can free the turning hook 637 from the pressure of the control plate 6311 of said wheel 631. Then the turning hook 637 moves nearer to the control plate 6311 already returned to its original position, pushed by the spring 6372.
  • said bolt 65 can automatically extend out of the holes 6113, 6123 by the resilient force of the spring 681, and said bolt 69 can also automatically extend out of the holes 6114, 6124 by means of the spring 695, 696.
  • the U-shaped base 692 also acquires an outward pushing force to push the sticking plate 636 back to the position shown in Figure 13 and the end slope of the arm 6364 of the sticking plate 636 can push the turning hook 637 to revolve a bit and then to return again so that the arm 6364 can enter the notch 6373 of said hook 637.
  • the turning button 24 is turned vertical. Under this position, the plate 26 becomes also vertical guided by the turning plate 25, the pin 453 stuck in the notch 263 of the plate 26 passing over the protrusion 264, the blocking tip 451 of the blocking plate 45 going up and not hampering the notch 493 of the rail 49, the moving base 44 entering the rail 49 pushed by the spring 43, the cross bar 441 sticking in the engaging grooves 463 and the notches 132 of the square shaft 13. Then this lock is totally unlocked. Under this position,
  • the moving base 44 retreats engaging no more with the notches 132 of the square shaft 13, the vertical back of the cross bar 441 and the vertical back of the blocking tip 451 leaning against each other, the moving base 44 becoming unable to enter the rail 49.
  • the upper and the lower dead bolts both extends out sticking in the holes of the restricting board 610 of the door frame, making up an reinforced locking function.
  • the upper dead bolt 66 it automatical­ ly extends out only when the door is closed and the middle dead bolt 69 is pressed in. Under this condition,
  • the acting time of the magnetic coil 16 should be be limited, and electricity to said coil 16 must be cut off if that time is up. Then the blocking tip 451 can fall down to occupy the notch 493. Therefore, if the lock is not opened in the limited period of time after the key card is inserted, the action of inserting the card should be repeated to open the lock.
  • the blocking tip 451 goes down to block the notch 493.
  • the moving base 44 has already moved by the knob 11, the upper part of the cross bar 441 slides down along the inside of the slope 494 of the rail 49 and gets off at the cut 495, and climbs up along the out­side of the slope 494. (The moving base 44 itself is turned back to the original position by the engaging base 46.) Consequently the cross bar 441 can return to the original position.
  • the latch 6 possesses the function of automatically replacing the turning button 24 to the original position after the knob 11 or 23 is turned. In other words, said button 24 is at the position unlocked again, the lock being free to open as a common cylinder lock.
  • Figure 18 shows the structure of the second example of a control wheel 631, wherein the stopping edge 6312 in the first example, i.e. that is already described above, is cut off and provided with a slope 6313 instead.
  • the slope 6313 is situated off the straight moving line of the arm 671 of the moving plate 67; so if the outside knob 11 is turned, the moving tube 64 is moved to pull in the lower dead bolt 65.
  • This invention comprises, as just described, two kinds of structure for the latch, selectable by a user, and either one is devised to enable both dead bolts, the upper and the lower to extend out so that the lock can be equipped with a reinforced security against burglary.
