The horizontal guide rod 82 is caulked and fixed at the rear end to a small support plate fixed to the center of the lock box 30, and the front end penetrates the support hole of the box-like connecting portion. The locking piece 77 is biased in the protruding direction by a locking spring for the locking piece wound around the horizontal guide rod 82.

  (I) Next, the locking piece holding mechanism 85 will be described. This locking piece holding mechanism 85 is an additional requirement of the present invention. The locking piece holding mechanism 85 holds the retracted state of the locking piece 77 when the door 20 is opened. The locking piece holding mechanism 85 is disposed below the locking piece 77, and in this embodiment, the first permanent magnet 33 on the side of the receiving bracket 32 and the second permanent magnet repelling the polarity of the first permanent magnet 33. And a control gear (which is provided at the other end of the swing piece 88 and meshes with the gear train 81 of the lock piece 77). For example, it includes an engaging claw piece 90 that engages with and disengages from a pinion 89 and a holding spring 91 that urges the swinging piece 88 in a direction in which the swinging piece 88 is always engaged.

  As shown in FIG. 2, the second permanent magnet 86 facing the first permanent magnet 33 through the opening 13 repels corresponding to the polarity (for example, N pole and N pole) at the time of locking. The engaging claw piece 90 is separated from the pinion 89, but when the door 1 is opened, the second permanent magnet 86 is separated from the first permanent magnet 33, so that the swing piece 88 is engaged by the holding spring 91. Rotate in the direction you want. As a result, since the engaging claw piece 90 engages with the pinion 89, the retracted state of the locking piece 77 is held by the constituent member 85 of the holding mechanism.

(U) First locking / unlocking mechanism 95 for locking piece
This 95 is an additional requirement of the present invention. The first locking / unlocking mechanism 95 is disposed above the locking piece 77 so that the protruding locking piece 77 can be locked directly when the door is closed. There are various means for locking the locking piece 77, but as an example of reducing the number of components, an advancing / retreating piece (common name) that collides with the metal fitting 32 side (strike or door frame) and moves backward in the lock box. "Trigger") 96, a first locking piece 98 in which the engaging portion 97 of the distal end engages with the connecting portion 79 of the locking piece 77 by the reciprocating movement of the advancing / retracting piece 96, and the first locking piece The center part is wound around the pivot 99 which supports 98, and the unlocking spring 100 always urges the locking piece 98 in the direction of disengagement.

(E) Second locking / unlocking mechanism 6 for locking piece
The drive source of the first locking / unlocking mechanism 6 is a necessary component for the electric lock. The second application / unlocking mechanism 6 has one end portion (upper end portion) pivotally supported by the operating rod 102 of the drive source (solenoid) 101 and a central portion (including a portion closer to the central portion). The second locking bar 104 is supported by the 30 fixed pivots 103 and the other end (lower end) engages with the contact protrusion 47A of the outer handle hub member 42. Therefore, the locking piece 77 is indirectly locked through the locking of the outer handle hub member 42.

(O) Others If other supplementary explanations are given, the thumb turn member 12 can be rotated independently regardless of the slide drive plate 14. That is, when a thumb turn knob (not shown) is rotated in the locking / unlocking direction, the thumb-turn member 12 rotates in the locking or unlocking direction regardless of the slide drive plate 14. As a result, the dead latch 77 moves back and forth. At this time, the signal can be picked up by the fourth detection means 15 in the same manner as when the slide drive plate 14 is lowered.

  Next, the operation of the present invention will be described. First, the flow of the lock signal and the unlock signal of the electric lock of the security system X will be briefly described. When the door 20 is closed, the control unit 3 that has received the closing signal using the movement of the advance / retreat member 96 or the like transmits a locking signal (g) to the drive source 101 of the second locking / unlocking mechanism 6. Then, the locking piece (for example, dead latch) 77 engaged with the receiving metal fitting 32 is locked.

  When the unlocking card 1 is inserted into the reading device 2 in the locked state as described above, the control unit 3 goes through the determination of the collation determining means 5 and then the drive source of the locking / unlocking mechanism 6. An unlock signal (a) is transmitted. Then, the locking / unlocking mechanism 6 drives the locking piece 104 in the unlocking direction. In the present embodiment, a solenoid is used as a driving source of the locking / unlocking mechanism 6, so that the locking signal (g) and the unlocking signal (a) are energized or de-energized with respect to the solenoid. Thus, after the locking of the locking piece 104 is released by the driving force of the driving source 101, the outer operation member 7.8 can be operated.

  Next, FIG. 7 is an explanatory view showing a state in which the members of the main part of the present invention are operated in relation to the detection means (in fact, such a figure cannot be present. Shows the movement.) For example, as can be understood from FIGS. 8 to 10, when the operation of the outer operation member 7.8 or the like becomes possible, as described above, one slide drive plate 14 is provided with the inner and outer handle hub members 41.42. Since the engaged portions 60 and 61, the thumb drive member 62 for the thumb turn member 12, and the engaged receiving portion 63 for the cylinder member 8 are respectively formed, the inner handle hub member 41 and the outer handle hub member 42 are formed. When the cylinder members 8 are individually rotated in the unlocking direction, the slide drive plate 14 is lowered downward by a predetermined amount, and the thumb turn member 12 is rotated clockwise in conjunction with the slide drive plate 14.

  As a result, the dead latch 77 moves backward. At that time, as described above, each of the first to fourth detection means detects a signal, and each detected signal is transmitted to the control unit 3 and recorded in the storage unit 4 as a history of mechanical operations. The

  When spread, for example, the first detection means 9 and the second detection means 10 detect the operation signals (b) and (c) corresponding to the respective operation members 7 and 8. Further, when the slide drive plate 14 moves downward, the thumb turn member 12 swings and the dead latch is pulled back into the lock box. However, when the thumb turn member 12 swings, the dead latch retracts into the lock box. A signal (e) indicating that this has occurred is detected by the fourth detection means 15.

  On the other hand, the third detection means 13 detects the operation signals (d) and (c) correspondingly when the inner handle 11 is operated. At this time, since the slide drive plate 14 moves downward, the thumb turn member 12 swings and the dead latch is pulled back into the lock box. Therefore, as in the case of the outer operation members 7 and 8, a signal (e) indicating that the dead latch has moved back into the lock box is detected.

  Further, in the present embodiment, when the door 20 is opened, the retracted dead latch 77 is held by the member 85 constituting the holding mechanism. At this time, the opening or closing signal is detected by the fifth detection means 21. The detection signal is recorded as a history in the storage unit 4 via the control unit 3.

  In the embodiment of the present invention, as the best mode, the bearing portion 45 of the inner handle hub member 41, the bearing portion 45A of the outer handle hub member 42, the thumb turn duller 51 of the thumb turn member 12, and the cylinder dharma 52 of the cylinder member 8 are required intervals. Although applied to electric locks that are spaced apart and arranged in a substantially vertical row, the present invention is not limited to this best mode.

  For example, when the inner and outer handles are respectively depressed, the inner operating member is applied to an electric lock having a lock handle device having a handle hub member that rotates a predetermined amount against the spring force of the spring member, and the outer operating member is operated. The embodiment in which the at least one detection means for detecting the rotation signal is provided is also included in the range of the present invention.

  The present invention is mainly used in the lock industry that manufactures, sells, and displays electric locks for doors that are attached to the doors of hotel rooms, laboratory laboratories, high-rise apartments, and the like.
