This control device 12a includes switch means, for example, normally closed relay contacts 16a and 18a, which are connected in series in order from the first power line 14.
Which are connected in series with the push button switch 22a of the elevation control means 20a. The push button switch 22a is connected to the contact 26a of the up / off / down switching key switch 24a. This changeover key switch 24a includes a rising contact 28a,
It has a disconnecting contact 30a and a descending side contact 32a, and the ascending side contact 28a is
It is connected to the second power line 38 via a normally closed upper limit switch 34a and an electromagnetic switch 36a which are opened when the parking device is raised to a predetermined position. This electromagnetic switch 36a
When energized, it closes the contacts 40a, 40a, 40a and rotates the motor 42a in a direction to raise the parking device 10a. Further, the descending side contact 32a is connected to the power line 38 through a series circuit of a normally open relay contact 44a and an electromagnetic switch 46a.
When energized, the electromagnetic switch 46a closes the contacts 48a, 48a, 48a and rotates the motor 42a in a direction to lower the parking device 10a.

Between the power supply lines 14 and 38, a normally-closed lower limit switch 50a which is opened when the parking device 10a is lowered and a relay drive coil 52a are provided as driving means for the first and second switching means. And are connected in series. When the relay drive coil 52a is energized, it closes the relay contact 44a, and also connects the first and second changeover switch means, for example, the contacts 58a and 60a of the changeover relay switches 54a and 56a to the second terminal. , From the contact 62a, 64a side to the first terminal, eg, contact 66a, 68a side.

The contacts 66a and 68a are connected to the power supply line 14, the contact 62a is connected to the power supply line 38a via a first driving means of the switching means, for example, the relay drive coil 70a, and the contact 64a is connected to the second switching means. It is connected to the power supply line 38 via a drive means, for example, a relay drive coil 72a. When the relay drive coil 70a is energized, it opens the relay contact 16a,
The relay drive coil 72a opens the relay contact 18a when energized.

The contact 60a of the changeover relay switch 56a is connected to the contactor 58b of the changeover relay switch 54b of the control device 12b through one interlock wire 74, and the contactor 60b of the changeover relay switch 56b of the control device 12b. Is connected to the contact 58c of the switching relay switch 54c of the control device 12c via one interlock wire 76, and the contact 60c of the switching relay switch 56c is the contact 58d of the switching relay switch 54d of the control device 12d. To the controller 12 via a single interlock wire 78.
It is connected to the contact 58e of the changeover relay switch 54e of e through one interlock wire 80.

The control device for the parking device configured as described above operates as follows. Now, as shown in FIG. 2, each parking device 10a
If 10 to 10e are in the descending state, the lower limit switch 50a
To 50e are in the open state, and relay drive coils 52a to 52e
e is in a non-energized state. As a result, the contacts 58a to 58e, 60a to 60e of the changeover relay switches 54a to 54e, 56a to 56e come into contact with the contacts 62a to 62e, 64a to 64e, and the relay drive coils 70a to 70e, 72a to 72e are de-energized. Since it is in the state, the relay contacts 16a to 16e and 18a to 18e are all in the closed state. The upper limit switches 34a to 34e are all in the closed state.

In this state, for example, as shown in FIG.
12c up / off / down key switch 24c contact 26c
Contacting the ascending side contact 28c and closing the push button switch 22c, the relay contacts 16c, 18c, the push button switch 22c, the up / off / down switching key switch 24c, the upper limit switch 34c, and the electromagnetic switch 36c are energized. Flow, contacts 40c, 40c, 40
c is closed, and the motor 42 rotates in a direction to raise the parking device 10c.

The lower limit switch 50c is closed due to the parking device 10c rising, the relay drive coil 52c is energized, the relay contact 44c is closed, and the changeover relay switch 5
The contact 58c of 4c switches from the contact 62c side to the contact 66c side, and the contact 60c of the changeover relay switch 56c switches from the contact 64c side to the contact 68c side.

As a result, a current flows to the relay drive coil 72b via the changeover relay switch 54c and the interlock wire 76, and the relay contact 18b is opened. Therefore, even if the contact 26b of the changeover key switch 24b of the control device 12b is switched to the ascending side contact 28b or the descending side contact 32b and the push button switch 22b is closed, the parking device 10b does not operate. Similarly, a current flows through the relay drive coil 70d through the changeover relay switch 56c and the interlock wire 78, and the relay contact 16d is opened. Therefore, even if the contact 26d of the changeover key switch 24d of the control device 12d is switched to the ascending side contact 28d or the descending side contact 32d and the push button switch 22d is closed, the parking device 10d does not operate. That is, the control devices 12b and 12d are interlocked and do not operate.

Eventually, when the parking device 12c continues to rise and rises to a predetermined height, the upper limit switch 34c is opened, the electromagnetic switch 36c is de-energized, the contacts 40c, 40c, 40c are opened, and the motor 42c is stopped. Then, the parking device 10c stops. Even in this state, since the relay drive coil 52c is still energized, the control devices 12b and 12d do not operate.

Then, the contactor 2 of the up / off / down switching key switch 24c
When 6c is switched to the descending side contact 32c side and the push button switch 22c is closed, the relay contact 44c is closed, so the electromagnetic switch 46c is energized and the contacts 48c, 48c, 48c are closed,
The motor 42c rotates in the direction in which the parking device 10c is lowered, and the parking device 10c starts descent. During this time, since the relay drive coil 52c is still energized, the control device 12b,
12d does not work. Then, when the parking device 12c descends to a predetermined position, the lower limit switch 50c is opened,
The relay drive coil 52c is de-energized, the contacts 58c, 60c of the changeover relay switches 54c, 56c are switched to the contacts 62c, 64c, the relay drive coils 72b, 70d are de-energized, and the relay contact 18b, 16d is closed, control device 12b, 12d
Are ready to operate. That is, the interlock is released.

The second embodiment is shown in FIG. In this embodiment, the present invention is applied to a control device for a two-stage parking device on the ground, and like the first embodiment, a total of five parking devices have the same configuration, that is, the control devices 12a to 12e. Is provided.
Since all have the same configuration, only the control device 12c will be described. Further, the same parts as those in the first embodiment are designated by the same reference numerals and the description thereof will be omitted. In the first embodiment, the relay contact 44
While c is connected in series with the electromagnetic switch 46c, in this embodiment, the lower limit switch 50c is the electromagnetic switch 46c.
Are connected in series. And this electromagnetic switch 46c
Contact 74c that is closed when electricity is applied to the electromagnetic switch 36c
A contact point 76c that is closed when a current is applied to the contact point is newly provided, these are connected in parallel and are connected in series to the relay drive coil 52c.

In this embodiment, when each parking device is in a stopped state, for example, in a lowered state, since the electromagnetic switches 46a to 46e, 36a to 36e are not energized, the contacts 74a to 74e, 76a to 76e are opened. . Therefore, since the relay drive coils 52a to 52e are not energized, the respective changeover relay switches 54a to 5e
4e, 56a to 56e contacts 58a to 58e, 60a to 60e are contact points
The relay drive coils 70a to 70e and 72a to 72e are connected to 62a to 62e and 64a to 64e, and the relay contacts 16a to 16e and 18a to 18e are closed. That is,
Any of the control devices 12a to 12e is ready for operation.

In this state, for example, when the contact 26c of the up / off / down switch key switch 24c of the control device 12c is switched to the contact 28c side and the push button switch 22c is closed, the electromagnetic switch 36c is energized and the first embodiment is executed. Similarly to, the parking device 12c starts to rise. At this time, since the contact 76c is closed, the relay drive coil 52c is energized, and the changeover relay switch 54c,
The contacts 58c, 60c of the switch 56c are switched to the contacts 66c, 68c to energize the relay drive coils 72b, 70d as in the first embodiment, and the control devices 12b, 12d do not operate.

Eventually, when the parking device 12c is raised to a predetermined position and the upper limit switch 34c is opened, the electromagnetic switch 36c is de-energized, the motor 42c is stopped, the contact 76c is opened, and the relay drive coil 52c. Is turned off, and contacts 58c and 60c of the changeover relay switches 54c and 56c are connected to contacts 62c and 6c.
Switching to the 4c side, the power supply to the relay drive coils 72b and 70d is cut off. As a result, the parking devices 12b and 12d become operable.

In addition, the up / off / down switch key switch 2 of the parking device 10c
Switch the contact 26c of 4c to the descending side 32c, and pushbutton switch 22
When c is closed, the electromagnetic switch 46c is energized and the parking device 10
c begins to fall. At this time, since the contact 74c is closed, the relay drive coil 52c is energized, the contacts 58c, 60c of the changeover relay switches 54c, 56c are switched to the contact 66c, 68c side, and the relay drive coils 72b, 70d. When the power is turned on, the control devices 12b and 12d become inoperable. Then, when the parking device 10c descends to a predetermined position and the lower limit switch 50c is opened, the electromagnetic switch 46c is de-energized, the contact 74c is opened, and the relay drive coil 52c.
Is turned off, the contacts 58c, 60c of the changeover relay switches 54c, 56c are switched to the contacts 62c, 64c, and the relay drive coils 72b, 70d are turned off, and the control devices 12b, 12d can be operated. It will be in a state.

That is, in the first embodiment, when the parking device starts to rise, the parking devices on both sides cannot operate even if the parking device is stopped in the raised state. However, in this embodiment, when the vehicle is raised and stopped, the parking devices on both sides become operable. This difference is because the first embodiment is a two-tiered pit parking apparatus, whereas the second embodiment is a two-tiered parking apparatus on the ground.

In the above embodiment, the relay contacts 16a to 16e, 18a to 18e
Was connected in series to the lifting control means 20a to 20e as a normally closed relay contact, the relay contacts 16a to 16e, 18a to 18e as a normally closed relay contact, and the normally open type relay contacts 16a to 16e as a resistor. Alternatively, the normally-open relay contacts 18a to 18e connected in series may be connected in series with the resistor, and these series circuits may be connected in parallel to the lifting control means. Further, although the relay is used in the above embodiment, a switching transistor or the like may be used instead of the relay.

[Advantages of the Invention] As described above, according to the present invention, when a parking device is operating, the parking devices on both sides of the parking device can be disabled, so that a person stands between the parking devices. However, the person can be prevented from being injured.
Moreover, in each of the control devices according to the present invention, in order to prevent the person standing between the parking devices from being injured as described above, the first and second changeover switching means of the certain control device are prevented.

The contact of the first changeover switching means is connected to the contact of the second changeover switching means of the control device of the parking device adjacent to the one side, and the contactor of the second changeover switching means is adjacent to the other side. The configuration is such that it is connected to the contacts of the first switching means of the control device of the device. Therefore, in order to prevent injury of a person standing between the parking devices, the wiring for the control device of the adjacent parking device is provided with the contact of the switching device of the control device of the parking device.
