As shown in FIGS. 3 and 4, the drive means 33 is, for example, a motor unit including a motor 37, various gears 38, a slider detection switch 34, a handle detection switch 35, and the like. The motor 37 moves the slider 20 so as to push it inward of the tubular body portion 4. The slider detection switch 34 is configured to be in contact with the slider 20, and is switched ON / OFF as the slider 20 moves. Further, the handle detection switch 35 can come into contact with the convex portion 6a provided on the back surface side of the handle 2 (grip portion 6), and ON / OFF is switched as the handle 2 moves. In the connector 39 connected to the drive means (motor unit) 33, for example, the first pin P1 and the second pin P2 are connected to the first terminal and the second terminal of the motor 37, respectively, and the third pin P3 and the fourth pin P4 are connected. Is connected to the handle detection switch 35, and the fifth pin P5 and the sixth pin P6 are connected to the slider detection switch 34 (FIG. 4B).

Further, the timer 36, for example, receives a release signal and measures the elapsed time until the handle detection switch 35 is turned “ON” after the release signal is authenticated.

In the door locking device 1 of the present embodiment, the states of the handle 2 (cylinder body portion 4), the handle case 3, and the inner case bolt 5 housed therein are the locked state and the unlocked state. It changes to the unlocked standby state. The locked state is a state in which the handle 2 (cylinder body 4) is restricted from protruding (pop-up) from the handle case 3 (inner case bolt 5), and the unlocked state is the handle 2 (cylinder). The body part 4) is in a state where it can protrude (pop-up) from the handle case 3 (inner case bolt 5) and in a state where it protrudes (pop-up), and the unlocking standby state is the handle 2 (cylinder body). This is a state in which the unlocking of the part 4) and the handle case 3 (inner case bolt 5) is awaited (details will be described later).

Although the details will be described later, in the unlocking standby state, the slider 20 tries to push the cannuki 15 by the driving force of the motor 37, but the motor 37 stops together with the slider 20 and the cannuki 15 while the driving force is applied. The handle 2 is in a state where it does not pop up from the handle case 3. In the unlocked standby state, the operator pushes the handle 2 to the rear of the tubular body portion 4 within a predetermined time to enter the unlocked state, and the handle 2 pops up.

5A and 5B are views showing a cylinder lock 8 housed in the handle 2 and its tubular body 4 and an inner case bolt 5, and FIG. 5A is a front view of the handle 2 and FIG. 5B is a front view of the handle 2. Is a cross-sectional view taken along the line aa in FIG. 6A, FIG. 3C is a left side view of the inner case bolt 5 and the handle 2, and FIG. 3D is b- in FIG. It is a cross-sectional view of line b. Further, FIG. 3E is a view of the cylinder lock 8, the cam portion 10 and the slider 20 viewed from the rear end portion of the cylinder portion 4 (to the right of FIG. 3B), and FIG. It is a right side view of FIG. (E), and the figure (g) is the left side view of the figure (e). The motor unit 33 is not shown in the figure.

As shown in FIGS. (A), (b), (f), and (g), a cylinder lock 8 and a cylinder ring 9 are attached to the cylinder body 4 of the handle 2. The cylinder ring 9 has an engaging hole (not shown here) in the center thereof, and the shaft portion behind the inner cylinder 8b of the cylinder lock 8 is inserted into the engaging hole of the cylinder ring 9 to insert the cylinder lock 8. It is incorporated into the handle 2 by screwing it into the cylinder ring and then screwing it with a round nut N.

A cam portion 10 is provided at the rear end portion of the cylinder ring 9 (FIG. (E)). Further, the handle 2 is provided with a cannuki 15 adjacent to the cam portion 10 (FIGS. (D) to FIG. (G)). The Kannuki 15 locks and releases the tubular body portion 4 of the handle 2 and the inner case bolt 5. Specifically, as shown in FIGS. (C) and (d), through holes 4a and 5a are provided in the tubular body portion 4 and the inner case bolt 5, respectively. With the door locking device 1 locked, the cannuki 15 penetrates through the through holes 4a and 5a. As a result, the tubular body portion 4 and the inner case bolt 5 are engaged with each other. The lengths of the through holes 4a and 5a in the front-rear direction (the length in the left-right direction in the figure (c)) are the lengths in the front-rear direction (width, the left-right direction in the figure (c)) of the cannuki 15. The cannuki 15 is provided to be larger than the length of (1), and moves slightly in the front-rear direction (horizontal direction in the figure (c)) as the handle 2 moves in the front-rear direction while penetrating the through holes 4a and 5a. It is configured to be possible.

Further, as shown in FIG. 6C, the tubular body portion 4 is provided with a guide pin 40, and the inner case bolt 5 is provided with an elongated hole 5b into which the guide pin 40 can slide. As a result, the tubular body portion 4 (handle 2) is slidable in the front-rear direction (left and right in the figure (c)) with respect to the inner case bolt 5 within the length range of the elongated hole 5b.

Further, referring to FIGS. (D) to (g), in the Kannuki 15, the diametrical end (lower end in this example) of the cylinder lock 8 is the end (upper end in this example) of the slider 20. ) And can be contacted. In this example, the slider 20 is configured to be movable in the vertical direction, and when it is moved in the upward direction, the slider 20 is pushed into the inside (upward direction) of the tubular body portion 4. Further, the cannuki 15 is directed toward the outer circumference of the tubular body portion 4 in the direction opposite to the pushing direction of the slider 20 by the cannuki urging means (for example, coil spring) 25 that abuts on the other end (upper end in this example). It is always urged (downward in this example).

The operation of locking / unlocking the door locking device 1 of the present embodiment will be described with reference to FIGS. 6 to 8. 6 (a) to 6 (j) are views showing the operation of the door lock device 1, each of which is a front view and a cross-sectional view taken along line cc of the lower figure. 7A and 7B are enlarged views of the portion marked with a broken line in FIG. 5C, FIG. 7A is a view in a locked state, and FIG. 7B is a view in a locked release standby state. 7 (c) and 7 (d) are diagrams in the process of transitioning from the unlocked standby state to the unlocked state. Further, FIG. 8 is a state transition table showing the state of the drive means (motor unit 33).

FIG. 6A shows the locked state of the door locking device 1. In this case, the tubular body portion 4 of the handle 2 is housed in the housing portion 3b (inner case bolt 5) of the handle case 3. Then, the lower end portion (right end portion in FIG. 6) of the cannuki 15 protrudes from the through hole 4a of the tubular body portion 4 and the through hole 5a of the inner case bolt 5 (FIGS. 5 (c) and 7 (a)). 15 locks the tubular body portion 4 and the inner case bolt 5. Further, the inner case bolt 5 and the lever 11 are screwed so as to sandwich the housing portion 3b of the handle case 3 from the front-rear direction, and the inner case bolt 5 can rotate with respect to the handle case 3 in the front-rear direction. I can't move to. As a result, the handle 2 (cylinder body portion 4), the inner case bolt 5, and the handle case 3 are in a locked state.

In the locked state, the tubular body portion 4 is urged forward (to the left in FIG. 7) by the urging force Fa by the coil spring 7 (see FIG. 1 (B)), and the cannuki 15 as shown in FIG. 7 (a). The front end portion 15s of the inner case bolt 5 comes into contact with the front end wall 5as of the through hole 5a of the inner case bolt 5. Then, a frictional force Fd is generated between the front end portion 15s of the cannuki 15 and the front end wall 5as of the through hole 5a according to the normal force of the urging force Fa. Further, the cannuki 15 is directed toward the outer periphery of the tubular body portion 4 by the cannuki urging means 25 (see FIGS. 5 (d) to 5 (g)) that abuts on the upper end portion (upper part of FIG. 7) (FIG. 7). In the example, it is always urged by the urging force Fb (downward).

Further, as shown in FIG. 8 (1), in the locked state, when "Low" is input to both the first pin P1 and the second pin P2 of the connector 39, the first terminal and the second terminal of the motor 37 are connected. In both cases, "Low" is input and the slider 20 is stopped. When "Low" is input to the motor 37, the rotation of the motor 37 is stopped. Further, both the handle detection switch 35 and the slider detection switch 34 are in the pressed state (“ON”).

When the door locking device 1 receives the unlocking signal and the control means 31 authenticates, the control means 31 transmits an unlocking command to the driving means 33 of the motor 37. As a result, the drive means 33 inputs "High" to the first terminal and "Low" to the second terminal of the motor 37 to instruct forward rotation (CW: rotation in the clockwise direction when viewed from the output shaft side) (FIG. 8). (2)). When the motor 37 rotates in the normal direction, the slider 20 moves inward of the tubular body portion 4 (leftward in FIG. 6) as shown in FIG. 6 (b). As a result, the end portion of the cannuki 15 comes into direct contact (contact) with the tip end portion of the slider 20, and the slider 20 moves to try to push the cannuki 15 inside the tubular body portion 4. Here, in the present embodiment, the pushing force Fc of the slider 20 driven by the motor 37 is set to a force larger than the urging force Fb of the Kannuki urging means 25. When the slider 20 starts moving due to the forward rotation of the motor 37, the slider detection switch 34 is released from being pushed in, and the slider detection switch 34 is turned “OFF”.

When the slider 20 is moved in the inner direction (left direction in FIG. 6) of the tubular body portion 4 by a preset maximum amount (for example, 5 mm), the lower end portion (right end portion in FIG. 6) of the cannuki 15 is inside. Immerse in the case bolt 5 inside the through hole 5a (to the left in FIG. 6).

However, in the present embodiment, in the state where the slider 20 is being pushed in by the forward rotation of the motor 37 (FIG. 6 (b)), as shown in FIG. 7 (b), the handle 2 is moved forward by the urging force Fa. Due to the normal force of the coil spring 7 that is about to be pushed out, a frictional force Fd is generated between the front end portion 15s of the cannuki 15 and the front end wall 5as of the through hole 5a.

Further, in the present embodiment, the resultant force of this frictional force Fd and the urging force (pushing force) Fb of the cannuki urging means 25 is set to be larger than the pushing force Fc of the slider 20 driven by the motor 37 ( Fb + Fd> Fc). Therefore, the lower end portion of the cannuki 15 (the lower end portion in FIG. 7 and the right end portion in FIG. 6) does not immerse inside the through hole 5a of the inner case bolt 5, and the handle 2 does not pop out from the handle case 3. There is. In the present embodiment, this state is referred to as an unlocking standby state. In the unlocked standby state, as shown in FIG. 8 (3), "High" is input to the first terminal (first pin P1) and "Low" is input to the second terminal (second pin P2). , The rotation of the motor 37 is forcibly stopped because the input 15 does not move.

Then, as shown in FIG. 6 (c), in the unlocked standby state, the operator moves the handle 2 to the rear side of the tubular body portion 4 (to the left in FIG. 6, FIG. 6) within a predetermined time (for example, within 10 seconds). Then, push it upward), and when the force Fa'balances with the urging force Fa of the coil spring 7 as shown in FIG. 7 (c), the tubular body portion 4, that is, the cannuki 15 also moves to the rear side (to the left in FIG. 6). Then, the front end portion 15s of the cannuki 15 and the front end wall 5as of the through hole 5a are separated from each other, and the frictional force Fd between the two disappears.

That is, the force applied to the cannuki 15 is the urging force Fb of the cannuki urging means 25 and the pushing force Fc of the slider 20 driven by the motor 37. Since the pushing force Fc of the slider 20 driven by the motor 37 is set larger than the urging force Fb of the cannuki urging means 25, the slider 20 is moved by the motor 37 to move the cannuki 15 upward in FIG. 6 (left side in FIG. 7). ) (FIG. 7 (d)), the lock between the cannuki 15 and the through holes 4a and 5a is released.

As a result, the locking of the tubular body portion 4 and the inner case bolt 5 is released, and the locking of the handle 2 and the handle case 3 is also released. The inner case bolt 5 has an elongated hole 5b provided on the inner peripheral surface along the front-rear direction (see FIG. 3C), and the tubular body portion 4 has, for example, a protruding guide that engages with the elongated hole 5b. Since the pin 40 is provided, when the Kannuki 15 releases these locks and the operator releases the push of the handle 2, the tubular body portion 4 has the guide pin 40 engaged with the elongated hole 5b. Guided and slidable in the front-rear direction with respect to the inner case bolt 5, the tubular body portion 4 is pushed forward by the coil spring 7 and protrudes from the handle case 3 (inner case bolt 5). That is, as shown in FIG. 6D, the handle 2 pops up from the handle case 3 and is in the unlocked state.

The pop-up of the handle 2 causes the convex portion 6a and the handle detection switch 35 to be in non-contact, and the handle detection switch 35 is turned “OFF”.

As described above, in the present embodiment, the unlocked state is set before the predetermined time elapses in the unlocked standby state after the authentication of the unlocking signal (FIG. 8 (1)) (for example, the motor 37. This is limited to the case where the operator pushes the handle 2 toward the rear side of the tubular body portion 4 at the start of normal rotation (within 10 seconds from FIG. 8 (2)).

That is, after the unlock signal is authenticated, the timer 36 monitors the time until the handle detection switch 35 is turned "OFF" in the unlocking standby state.

Then, after the unlock signal is authenticated, for example, when the handle detection switch 35 is turned "OFF" by the pop-up of the handle 2 within a predetermined time from the start of normal rotation of the motor 37 (FIG. 8 (2)) (FIG. 6 (d)). ), When the determination is “Y” in FIG. 8 (4), the control means 31 transmits a stop command to the drive means 33. As a result, the drive means 33 inputs "High" to both the first terminal and the second terminal of the motor 37 to stop (brake) the reverse rotation of the motor 37 (FIG. 8 (10)).

In the unlocked state, the elongated hole 5b of the inner case bolt 5 and the guide pin 40 of the tubular body portion 4 are engaged with each other, so that the tubular body portion 4 is inside the handle case 3 with respect to rotation in the circumferential direction. It can rotate integrally with the case bolt 5. The inner case bolt 5 cannot move in the front-rear direction with respect to the handle case 3, but can rotate about the inner cylinder 8b (axis) of the cylinder lock 8. That is, the tubular body portion 4 and the handle 2 are slidable in the front-rear direction (left and right in the figure) with respect to the inner case bolt 5 and the handle case 3, and the handle case 3 is integrated with the inner case bolt 5. It becomes rotatable.

The cannuki 15 immersed in the tubular body portion 4 is urged in the outer peripheral direction of the tubular body portion 4 by the urging force of the cannuki urging means 25, but the tubular body portion 4 protrudes from the inner case bolt 5. Since the inner wall of the tubular body portion 4 exists on the outside of the through hole 5a of the inner case bolt 5, the cannuki 15 cannot project outward, and the state of being housed in the tubular body portion 4 is maintained.

That is, in this state, the handle 2 pops up from the handle case 3 and is rotatable. Then, when the pop-up handle 2 is rotated in a predetermined direction, the tubular body portion 4 and the inner case bolt 5 engaged with the tubular body portion 4 are rotated, and the lever 11 and the lever 11 attached to the rear end of the inner case bolt 5 are rotated. The lock cam rotates and drives the door lock mechanism to unlock the door.

After that, the control means 31 transmits an energization stop command to the drive means 33. The drive means 33 inputs "Low" to both the first terminal and the second terminal of the motor 37 to stop the energization of the motor 37 (FIG. 8 (11)). As a result, the door locking device 1 returns to the locked state (FIG. 8 (1)).

On the other hand, by the operator within a predetermined time (for example, within a predetermined time from the start of normal rotation of the motor 37 (FIG. 8 (2))) in the unlocked standby state after the authentication of the release signal (FIG. 8 (1)). If the handle 2 is not pushed in, the handle detection switch 35 remains “ON”. That is, for example, when the handle detection switch 35 remains “ON” after a predetermined time has elapsed from the start of normal rotation of the motor 37 (FIG. 8 (2)) (when the determination is “N” in FIG. 8 (4)). ), The control means 31 determines that an error has occurred (“1” is set in the error flag provided in the storage means (not shown)) (FIG. 8 (5)), and a stop command is transmitted to the drive means 33. The forward rotation of the motor 37 is stopped (brake is applied) (FIG. 8 (6)).

That is, for example, after a predetermined time has elapsed from the start of normal rotation of the motor 37 (FIG. 8 (2)), the slider 20 is not pushed by the normal rotation stop of the motor 37, and the cannuki 15 is the through hole 5a of the inner case bolt 5. Remains engaged with. Therefore, even if the operator pushes the handle 2, the handle 2 does not pop up and returns to the locked state (the locked state of the handle 2 and the handle case 3).

Even when the motor 37 stops rotating forward without the handle 2 popping up (FIG. 8 (6)), the control means 31 transmits a locking command to the drive means 33. As a result, the drive means 33 inputs "Low" to the first terminal of the motor 37 and "High" to the second terminal to reverse the motor 37 (CCW: rotate counterclockwise when viewed from the output shaft side) ( FIG. 8 (7). Due to the reversal of the motor 37, the slider 20 moves in the direction opposite to the pushing direction and returns to the locked position.

The timer 36 monitors the time from the start of the locking command (FIG. 8 (7)) by the control means 31 until the slider detection switch 34 is turned “ON”. Then, when the slider detection switch 34 is turned "ON" before the elapse of the predetermined time (for example, within 3 seconds from the start of the locking command (FIG. 8 (7))), the determination in FIG. 8 (8) is ". In the case of "Y"), assuming that the slider 20 has operated normally (the slider 20 has returned to the normally locked position), the control means 31 stops at the drive means 33 as shown in FIG. 8 (10). Send a command. As a result, the drive means 33 inputs "High" to both the first terminal and the second terminal of the motor 37 to stop the reverse rotation of the motor 37 (brake). After that, the control means 31 transmits an energization stop command to the drive means 33. As a result, the drive means 33 inputs "Low" to both the first terminal and the second terminal of the motor 37 to stop the energization of the motor 37 (FIG. 8 (11). Thereby, the door locking device 1 It returns to the locked state (Fig. 8 (1)).

On the other hand, for example, when the slider detection switch 34 does not turn “ON” (remains “OFF”) within a predetermined time from the start of the locking command (FIG. 8 (7)) by the control means 31 (FIG. 8 (8)). (In the case of "N"), the control means 31 determines that the slider 20 does not return to the normal locking position due to some problem, and determines an error (sets "1" in the error flag) (FIG. 8 (FIG. 8). 9)).

Then, as shown in FIG. 8 (10), the control means 31 transmits a stop command to the drive means 33. As a result, the drive means 33 inputs "High" to both the first terminal and the second terminal of the motor 37 to stop the reverse rotation of the motor 37 (brake). After that, the control means 31 transmits an energization stop command to the drive means 33. The drive means 33 inputs "Low" to both the first terminal and the second terminal of the motor 37 to stop the energization of the motor 37 (FIG. 8 (11)). As a result, the door locking device 1 returns to the locked state (FIG. 8 (1)).

The error flag is cleared (“0” is set) when the locked state of FIG. 8 (1) is restored.

When the door locking device 1 is locked, the operator closes the door, rotates the handle 2 in the opposite direction to return it to its original position, and resists the urging force of the urging means (coil spring) 7 as shown in FIG. 6 (f). Then push the handle 2 backward. As a result, when the positions of the through hole 4a of the tubular body portion 4 and the through hole 5a of the inner case bolt 5 are overlapped at the position of the cannuki 15, the cannuki 15 is automatically moved toward the outer peripheral direction of the tubular portion 4 by the urging force of the coil spring 25. The lower end is inserted into and engaged with the through holes 4a and 5a. As a result, the tubular body portion 4 is again locked to the inner case bolt 5 and the handle case 3 (in a locked state), and the door locking device 1 is locked.

6 (g) to 6 (j) show an emergency unlocking method. The door lock device 1 of the present embodiment is electronically (electrically) unlocked by receiving an unlock signal, but is a cylinder lock housed in the tubular body 4 in an emergency such as a power failure. It can be unlocked manually by 8.

The cylinder lock 8 is a pin tumbler lock in which the rotation of the cylinder is controlled by a pin-shaped driver pin and a tumbler as an example. Since the pin tumbler lock is the same as the known one, illustration and detailed description are omitted, but it is composed of an outer cylinder 8c and an inner cylinder 8b (see FIG. 5B), and crosses two cylinders inside. A set of multiple driver pins and tumblers is installed, and the rotation of the cylinder is controlled by the driver pins and tumblers.

When the key is not inserted into the keyhole 8a of the cylinder lock 8, the driver pin is pushed by the spring and is located across the boundary between the outer cylinder 8c and the inner cylinder 8b, so that the inner cylinder 8b does not rotate with respect to the outer cylinder 8c. It becomes. On the other hand, when the key is inserted, the uneven mountain of the key lifts the tumbler, and the boundary between the inner cylinder 8b and the outer cylinder 8c coincides with the boundary between the driver pin and the tumbler (the share line matches), so the inner cylinder 8b Rotates freely.

FIG. 6 (g) is a locked state (locked state of the handle 2 and the handle case 3) similar to that of the figure (a).

The figure (h) shows a state in which the correct key is inserted into the keyhole 8a of the cylinder lock 8 and rotated in a predetermined direction (for example, in the clockwise direction). When the key rotates, the inner cylinder 8b of the cylinder lock 8 rotates about the axis (FIG. 5 (b)).

Along with this, the cam portion 10 engaged with the inner cylinder 8b at the rear portion of the cylinder lock 8 rotates, for example, in the clockwise direction. As shown in FIG. 5 (e), since the cam portion 10 is engaged with the cannuki 15, the cannuki 15 moves to the left in the illustrated state due to the rotation of the cam portion 10 and is immersed in the tubular portion 4. .. When the cannuki 15 is immersed in the tubular body portion 4, the locking between the tubular body portion 4 and the inner case bolt 5 is released in the same manner as in the normal operation described above. In this case, since the cannuki 15 is moved by the rotation of the cam portion 10, a force larger than the resultant force of the frictional force Fd between the cannuki 15 and the inner case bolt 5 and the urging force (pushing force) Fb of the cannuki urging means 25 is applied. It can be given to the cannuki 15 and can be immersed in the tubular body portion 4.

When the cannuki 15 is immersed in the tubular body portion 4 by the rotation of the cam portion 10, the lock release state is reached without going through the lock release standby state between the handle 2 and the handle case 3. That is, the handle 2 pops up from the handle case 3 without pushing the handle 2 (FIG. 8 (i)).

After the handle 2 pops up, it is the same as the case of normal operation. That is, the cylinder body 4 is fixed to the handle 2, and the inner case bolt 5 cannot move in the front-rear direction with respect to the handle case 3, but rotates around the axis of the inner cylinder 8b of the cylinder lock 8. Movement is possible. That is, when the tubular body portion 4 and the inner case bolt 5 are released from the lock by the Kannuki 15, the lock between the handle 2 and the handle case 3 is also released. The tubular body portion 4 and the handle 2 are slidable in the front-rear direction (left and right in the figure) with respect to the inner case bolt 5 and the handle case 3, and the handle case 3 is integrated with the inner case bolt 5. It becomes rotatable.

Since the key cannot be pulled out in the state of the cam portion 10 rotated in the figure (i), as shown in the figure (j), the key is rotated counterclockwise, for example, to return the inner cylinder 8b to the original position. Return to and remove the key from the keyhole 8a. The operation at the time of locking is the same as that in the case of normal operation ((f) in the figure).

As described above, according to the present embodiment, the cylinder lock 8 is mounted inside the handle 2 (inside the tubular body portion 4) of the door lock device 1. Therefore, even when the conventional non-electronic door lock device is replaced with the electronic door lock device of the present embodiment, the replacement work can be easily performed, and the range thereof is also minimized. be able to.

Specifically, for example, a door lock device such as a vending machine currently in widespread use does not have a cylinder lock inside or outside the handle, but has a handle, an inner case bolt, and a handle case. A configuration in which a lock cam is rotated via an inner case bolt by rotation of a pop-up handle to drive a door lock mechanism, a structure having a cylinder lock inside the handle (see, for example, Patent Document 1), and a handle A configuration in which a cylinder lock is provided externally (see, for example, Patent Document 2) is known.

However, when replacing the already installed door lock device with an electronic door lock device having a cylinder lock on the outside of the handle, there are many restrictions on the work. Specifically, the door lock device to be replaced (already installed) must be externally equipped with a cylinder lock built into the handle to attach a cylinder lock for emergency unlocking. It may not be possible to replace it, or the replacement work may be complicated and extensive.

Even if the existing door lock device has an external cylinder lock, if the positional relationship between the handle and the cylinder lock is different from the electronic door lock device to be replaced, the replacement is still impossible. Possible or replacement work may be complex and extensive.

Further, if the existing door lock device does not have a cylinder lock, it cannot be replaced in the first place.

On the other hand, with the door lock device 1 of the present embodiment, the above-mentioned replacement work can be easily performed within a minimum range, and the replacement demand can be flexibly met.

Further, when unlocking using the cylinder lock 8 in an emergency, the cam portion 10 provided at the rear end portion of the cylinder lock 8 can be rotated substantially directly with the rotation of the key. Therefore, the force related to the rotation of the key (physical key) can be reduced as compared with the conventional technique of transmitting the rotation of the inner cylinder 8b of the cylinder lock 8 to the door lock device via the plate, and the unlocking becomes easier. ..

Further, if a thin and long plate is interposed when transmitting the rotation of the inner cylinder 8b of the cylinder lock 8, the plate is likely to be burdened, and if deformation occurs, emergency unlocking by the cylinder lock may not be possible. There is also. However, according to the present embodiment, such a plate becomes unnecessary, so that such a problem can be avoided.

<Second Embodiment>
A second embodiment of the present invention will be described with reference to FIGS. 9 and 10. FIG. 9 is an exploded perspective view showing a main configuration of the door lock device 1 of the second embodiment. Further, FIG. 10 is a view showing a cylinder lock 8 housed in the handle 2 and the tubular body portion 4 according to the second embodiment and an inner case bolt 5, and FIG. 10A is a front view of the handle 2. (B) is a sectional view taken along line dd of FIG. (A), FIG. (C) is a left side view of the inner case bolt 5 and the handle 2, and FIG. FIG. 5 is a cross-sectional view taken along the line EE of FIG. Further, FIG. 3E is a view of the cylinder lock 8, the cam portion 60, and the slider 20 viewed from the rear end portion of the cylinder portion 4 (to the right of FIG. 3B), and FIG. It is a right side view of FIG. (E), and the figure (g) is the left side view of the figure (e). The motor unit 33 is not shown in the figure.

In the first embodiment described above, the example in which the number of Kannuki 15 is one has been described, but a plurality of Kannuki 15 may be used.

9 and 10 show an example of having two cannuki 55 (cannuki 55A, 55B) as an example. In this case, the two cannuki 55s (cannuki 55A, 55B) are arranged so as to be point-symmetrical with the inner cylinder 8b (axis) of the cylinder lock 8 as the center. The through holes 4a and 5a of the tubular body portion 4 and the inner case bolt 5 are provided at positions where the lower end portions and the upper end portions thereof can be inserted, corresponding to the Kannuki 55A and 55B.

Further, as shown in FIGS. 10 (d) to 10 (f), the blade-shaped portion 10a of the cam portion 60 has a substantially circular shape as a point object centered on the inner cylinder 8b (axis) of the cylinder lock 8. Arrange so that Kannuki 55A and 55B are engaged with the wing-shaped portion 60a, respectively. Other configurations are the same as those in the first embodiment. That is, the door lock device 1 of the second embodiment has two cannukis 55A and 55B, but the slider 20 for moving these may be one as in the first embodiment.

The operation of locking / unlocking the door locking device 1 is the same as that of the first embodiment. That is, the unlocking signal is received in the locked state (the locked state of the handle 2 and the handle case 3), and after the authentication, the motor 37 is driven to push one slider 20 inward of the tubular body portion 4. As a result, one Kannuki 55A that comes into contact with the slider 20 is pushed into the tubular body portion 4. The cannuki 55A is engaged with one of the blade-shaped portions 60a, and the cam portion 60 rotates, for example, counterclockwise as the cannuki 55A moves (pushes in). As a result, the other blade-shaped portion 60a rotates, and the other Kannuki 55B engaged with the other blade-shaped portion 60a is drawn into the tubular body portion 4. In this embodiment, the circular blade-shaped portions 60a are always in contact with each other so as to be able to move up and down with the rotation of the cam portion 60. It is said.

When both Kannuki 55B are immersed inside the tubular body portion 4, the lock release standby state is set, and the handle 2 is pushed in within a predetermined time from the reception of the unlock signal to be in the unlock state, and the handle 2 is released from the handle case 3. Pops up.

In the second embodiment, since a plurality of cannuki 55s are provided, it is possible to prevent unauthorized unlocking of the door lock device 1 and enhance safety. In addition, since only one cannuki 55 is operated by the drive means 33 and the slider 20, it is possible to avoid complicated control of locking / unlocking of the door locking device 1 (due to an increase in the number of cannuki 55 to be operated). it can.

The door locking device 1 of the present invention is not limited to the above-described embodiment, and it goes without saying that various modifications can be made without departing from the gist of the present invention.

For example, the door locking device 1 of the present invention is not limited to the one that locks and unlocks the door of the vending machine, and may be the one that locks and unlocks the door of a safe, a warehouse, and the like.

Further, regarding the time monitored by the timer 36, the above time is an example, and the time is not limited to this.

Further, the communication means 32 may use a mobile phone network or satellite communication, and may be wired communication as well as wireless communication.

The drive means 33 is not limited to the motor unit, and may be a unit using a known drive source (for example, a solenoid or the like) which is an alternative means of the motor 37.

Further, the case where the cylinder lock 8 is a pin tumbler lock has been described as an example, but the present invention is not limited to this, and for example, a disc tumbler lock or a lever tumbler lock may be used.

Further, in addition to receiving the unlocking signal, the communication means 32 provides information such as locking and unlocking of the operator in the door locking device 1 and the state of the door locking device 1 to an external device (for example, information). It may be transmitted to a communication terminal or the like).
