C14H: Re-drive count storage unit The re-drive count storage unit C14H stores a set count Na that is a set value of the re-drive count, which is an upper limit count for repeating the contact / separation operation. In the first embodiment, 5 “times” is stored as an example of the set number of times Na.

C14J: Repeat count discriminating means The repeat count discriminating means C14J discriminates whether or not the repeat count N1 counted by the repeat count counting means C14G is equal to or greater than the set count Na.
C14K: Fee adjusted signal receiving means The fee adjusted signal receiving means C14K receives a fee adjusted signal specifying that the fee has been settled, which is transmitted when payment is made by the charging device 6.

C14L: Permitted Position Movement Control Unit The permitted position movement control unit C14L controls the motor 22 to move the lock plate 41 to the permitted position shown in FIG. When the permission position movement control means C14L according to the first embodiment receives the fee settlement signal, the permission position movement control unit C14L drives the motor 22 to rotate in reverse to move the lock plate 41 to the permission position.
C14M: Permitted Position Movement Determination Unit The permitted position movement determination unit C14M determines whether the lock plate 41 has moved to the permitted position shown in FIG. 2 based on the detection signal of the standby position detection sensor SN1.

C15: Participation determination time storage means The participation determination time storage means C15 stores an entry determination time t2, which is the time it takes for the vehicle to enter after payment is made. In the first embodiment, when the vehicle is parked in the parking space 1a after the payment, the vehicle enters the parking space 1a after the payment is made by the charging device 6 as a waiting time for resuming the charging. The participation determination time t2 = 10 minutes, which is the set time until the time is stored, is stored, but this time t2 can be arbitrarily changed according to the design or the like.
TM2: Participation discriminating time counting timer The participating discriminating time timer TM2 counts the participation discriminating time t2, and the time is up when the parting discriminating time t2 elapses.

C16: Participation discrimination means The participation judgment means C16 discriminates whether or not the vehicle has entered based on the detection result of the parking sensor 7. The participation determination means C16 of the first embodiment determines that the vehicle has participated when the parking sensor 7 no longer detects the vehicle after payment.
C17: Unauthorized escape determining means The unauthorized escape determining means C17 determines that an unauthorized escape has occurred when the parking sensor 7 no longer detects the vehicle in a state where the lock plate 41 has moved to the restricted position.

(Operation of Example 1)
In the parking apparatus 2 according to the first embodiment having the above-described configuration, when the vehicle is not parked in the parking space 1a (when not parked), the spring unit 26 moves to the rear standby position as shown in FIG. Therefore, the restricting member 21 has moved to the overlying permitted position. Therefore, it is in a state where parking of the vehicle is permitted, that is, in a state where parking is possible in the parking space 1a.

(Operation at goods receipt)
2 and 3, when the parking of the vehicle is detected in the parking space 1a, the motor 22 is driven, the drive shaft 24 is rotated, and the boss portion 27a in which the screw portion 24a of the drive shaft 24 and the screw portion 27a1 are engaged with each other. Moves forward, and the spring unit 26 moves forward. At this time, the front frame 27 and the rear frame 28 of the spring unit 26 are moved away from each other while being kept apart by the elastic force of the coil springs 37 and 38.

When the spring unit 26 moves forward, the pressing portion 39 of the spring unit 26 moves forward, and pushes the pressed protrusion 43a that comes into contact against the urging force of the torsion spring 44. As a result, the lock plate 41 rotates around the restriction shaft 42.
And if regulation position detection sensor SN2, SN3 detects the to-be-pressed part 43a, the drive of the motor 22 will be stopped and the movement to the advance position (refer FIG. 3) of the spring unit 26 will be completed. Therefore, the spring unit 26 moves from the standby position (see FIG. 2) to the advanced position (see FIG. 3), and the lock plate 41 rotates from the permission position (see FIG. 2) to the restricting position (see FIG. 3).

  In the restricting position, the lock plate 41 is held at the restricting position with the spring unit 26 meshing with the drive shaft 24 and the boss 27a, and the movement of the vehicle is restricted. That is, a high-performance, large-sized and expensive brake mechanism is unnecessary. Therefore, the parking device 2 can be reduced in size and thickness, and it is unnecessary to embed at the time of installation or the amount of embedment is small, and the installation cost can be reduced.

(Operations when there is insufficient warehousing of vehicles)
FIG. 8 is an explanatory view showing a state where the lock plate is in contact with the vehicle body in a state where the vehicle is not sufficiently received, and is a cross-sectional explanatory view of a main part corresponding to FIGS. 2B and 3B.
As shown in FIG. 3, in a state where the vehicle is sufficiently stored, even if the lock plate 41 moves to the restriction position, the vehicle body B and the lock plate 41 do not contact each other, and the vehicle body B is prevented from being damaged. .
On the other hand, when the vehicle is insufficiently received, the lock plate 41 comes into contact with the vehicle body B while the lock plate 41 moves from the permitted position to the restricted position, as indicated by a two-dot chain line in FIG.

In the first embodiment, when it is detected that the voltage of the motor 22 controlled by constant current is reduced and the lock plate 41 is in contact with the vehicle body B, the processing of ST7, ST10 to ST12 in FIG. The lock plate 41 moves in the direction away from the vehicle body B for a reverse rotation time t3 corresponding to a preset separation amount, and the lock plate 41 is held in a state of being separated from the vehicle body B as shown by the solid line in FIG. The Therefore, damage to the vehicle body B is reduced.
Even if the movement of the spring unit 26 overshoots, it can be buffered by the elastic deformation of the torsion spring 44 and the elastic deformation of the first coil spring 37, which will be described later, and damage to the vehicle can be reduced to a minimum.

In the first embodiment, when the lock plate 41 is separated from the vehicle body B, the processes of ST16 and ST17 are performed, and each time the waiting time t4 (30 minutes in the first embodiment) elapses, the process is repeated. The lock plate 41 starts to move again toward the restriction position side by the number of times N1. Therefore, when the driver moves the vehicle B and enters the vehicle fully after the previous lock plate 41 is stopped, the lock plate 41 is not held in a state where it is stopped at the middle half position, but is regulated. Move to position. Therefore, in the state where the lock plate 41 is stopped at the halfway position, the regulation of the delivery of the vehicle B becomes insufficient. However, in the first embodiment, the lock plate 41 tries to move to the regulation position every time the waiting time t4 elapses. Therefore, it can be reduced that the regulation becomes insufficient. further,
Therefore, in order to escape the parking fee, the vehicle B was intentionally stored in an inadequate state at the time of warehousing, and after confirming that the lock plate 41 stopped before moving to the restricted position, the vehicle B was admitted to the back. Even in this case, the lock plate 41 can be moved to the restriction position, and the vehicle B can be reliably restricted.

  Further, in the first embodiment, the lock plate 41 is moved to the restriction position by the preset number of repetitions N1, and when the lock plate 41 is moved to the restriction position by the number of repetitions N1, the lock plate 41 is moved. The movement to the restriction position is not performed. If the driver accidentally parks in an inadequate state or the vehicle body B is long and tries to move to the restricted position an infinite number of times, the contact between the lock plate 41 and the vehicle body B is repeated. The vehicle body B may be damaged. Therefore, in the parking apparatus 2 according to the first embodiment in which the movement to the restriction position is performed by the repetition number N1 which is a finite number of times set in advance, the contact between the vehicle body B and the lock plate 41 can be limited to the minimum necessary.

(Operation after fee settlement)
When it is detected that the payment by the charging device 6 has been performed, the motor 22 is driven in reverse rotation, and the spring unit 26 returns from the advanced position (see FIG. 3) to the standby position (see FIG. 2). At this time, the lock plate 41 is returned to the permission position (see FIG. 2) from the restriction position (see FIG. 3) by the torsion spring 44, the movement of the vehicle is permitted, and the lock plate 41 can leave the parking space 1a.

(Explanation when the goods are issued without charge settlement)
3 and 4, in the state where the lock plate 41 has moved to the restriction position, if the vehicle driver moves the vehicle by mistake due to negligence or error such as forgetting the settlement, vehicle B (see FIG. 4). The movement is restricted by contacting the lock plate 41 and the driver can be informed that he has forgotten the settlement. In the parking apparatus 2 according to the first embodiment, when the vehicle B comes into contact with the lock plate 41 at the restriction position, the lock plate 41 is pushed by the vehicle B, and the erroneous escape restriction position (see FIG. 4). Move towards). Thereby, the pressing portion 39 is pushed rearward by the pressed protrusion 43a, and the front frame 28 receives a force for moving backward. At this time, since the rear frame 27 cannot move due to meshing with the drive shaft 24, the first coil spring 37, which has a smaller spring constant than the second coil spring 38 and easily contracts, is compressed, and the rear frame 27 is not moved. Thus, the front frame 28 moves rearward.

  Therefore, if the lock plate 41 is configured to be unmovable at the restriction position shown in FIG. 3, the lock plate 41 and internal devices are damaged by an impact when the vehicle B is in contact, but the parking device 2 according to the first embodiment. Then, the lock plate 41 is configured to be movable to the erroneous escape restriction position. At this time, the first coil spring 37 is elastically deformed to provide a buffer, so-called cushion, and damage to the vehicle B and the lock plate 41 is reduced. Therefore, the driver who notices that the vehicle B comes into contact with the lock plate 41 and that the lock plate 41 is standing up stops the vehicle or returns the vehicle to the parking space 1a and adjusts the lock plate 41. It is possible to return to the permission position (see FIG. 2) and take out. When the vehicle is returned to the parking space 1a, the lock plate 41 returns from the erroneous escape restriction position to the restriction position due to the elastic restoration of the first coil spring 37.

3 to 5, if the driver does not notice that the vehicle is in contact with the lock plate 41 at the erroneous escape restriction position shown in FIG. When the lock plate 41 is moved, the lock plate 41 moves from the erroneous escape restriction position toward the unauthorized escape restriction position shown in FIG.
4 and 5, when the lock plate 41 is pressed by the vehicle B, the pressed protrusion 43a presses the pressing portion 39 and the front frame 28 tends to move backward. At this time, when the first coil spring 37 that is easily elastically deformed is elastically deformed and the elastic restoring force is increased, the first coil spring 37 is not further compressed, and the movement of the front frame 28 relative to the rear frame 27 is stopped. In this state, the first spring front end support surface 28c and the first spring rear end support surface 33b move to a first approach position (see FIG. 4) that is close to each other.

When the front frame 28 moves to the first approach position, the first coil spring 37 is not compressed any further, and the shaft 31 starts moving with respect to the rear frame 27 and is less elastically deformed than the first coil spring 37. The two-coil spring 38 starts elastic deformation.
Thereby, the front frame 28 moves relatively rearward. In FIG. 5, when the lock plate 41 moves to the unauthorized escape restriction position, the second spring rear end support surface 27b3 and the second spring front end support surface 33 move to the second approach position where they are close to each other.

Therefore, in the parking device 2 of the first embodiment, when the vehicle B is to be released without stopping even at the erroneous escape restriction position, the second coil spring 38 having a large elastic constant is elastically deformed, and the lock plate 41 is improper. It is configured to be movable to the escape restriction position side, and the damage to the lock plate 41 when the vehicle B tries to forcibly escape is reduced.
At this time, since the elastic constant of the second coil spring 38 is larger than the elastic constant of the first coil spring 37, the force required to rotate the lock plate 41 is the force between the restriction position and the erroneous escape restriction position. Compared to the above, a large force is required discontinuously, and the movement of the vehicle B is easily regulated, and the driver is easily prompted to be regulated.

Further, since the second coil spring 38 having a high elastic coefficient is elastically deformed, the contact pressure between the lock plate 41 and the vehicle B is increased, and the lock plate 41 rubs against the bottom surface of the vehicle B, and noise is generated. It is easy to recognize that it is regulated. Even if the vehicle B is intentionally escaped without paying out, the noise makes it easier for parking managers and residents in the surrounding area to notice, making it difficult to escape illegally. Since the contact pressure causes damage to the vehicle B and the like, it is deterred against unauthorized escape.
Further, in the first embodiment, the front end of the vehicle B is easily caught by the claw portion 41c, and the vehicle contact surface 41c1 is inclined with respect to the vehicle B as the lock plate 41 is inclined and approaches the unauthorized escape restriction position. It has a shape that strikes close to the face. Therefore, it is easy to prevent unauthorized escape of the vehicle B.

Therefore, in the parking device 2 of the first embodiment, the vehicle is regulated while the breakage of the lock plate 41 is reduced.
At this time, in the parking apparatus 2 according to the first embodiment, when priority is given to reducing damage to the vehicle B or the lock plate 41 by the selection of the manager of the parking lot, coil springs having a small elastic constant are used as the coil springs 37 and 38. Even if the possibility of breakage is high, it is possible to use a coil spring having a large elastic constant as the coil springs 37 and 38 in order to increase the regulating force to prevent unauthorized escape. That is, by adjusting / changing the balance of the elastic constants of each of the coil springs 37 and 38, the difference in elastic constants, etc., when the vehicle B comes into contact with the lock plate 41, the vehicle is damaged or the lock plate 41 is damaged. Can be selected and adjusted.

FIG. 9 is an explanatory view of the parking apparatus according to the first embodiment of the present invention, FIG. 9A is a plan view in a state where the regulating plate has moved to the winding position, and FIG. 9B is a cross-sectional explanatory view of the main part of FIG.
4 and 9, in the case of the vehicle B having a high vehicle height at the erroneous escape restriction position, the tip of the lock plate 41 may sink into the lower surface of the vehicle B at the erroneous escape restriction position. In this state, when the driver of the vehicle B notices and returns the vehicle to the parking space 1a, the lock plate 41 that has entered the lower surface of the vehicle B is moved to the restricted position as the vehicle B moves as shown in FIG. It may be caught in the rear side. At this time, in the parking device 2 according to the first embodiment, the pressing portion 39 and the pressed protrusion 43a are configured to be able to contact and separate from each other, and accordingly, the torsion spring according to the movement of the vehicle B to the inside of the parking space 1a. It moves to the entrainment position shown in FIG. Therefore, the breakage of the lock plate 41 can be reduced and the breakage of the parking device 2 can be reduced as compared with the configuration incapable of moving from the restriction position to the winding position side. When the lock plate 41 moves to the winding position side and the contact between the lock plate 41 and the vehicle B is released, the lock plate 41 is moved from the winding position (see FIG. 9) to the restricted position (see FIG. 9) by the torsion spring 44. Return to FIG.
