The boarding room 1 has an entrance 3 with a door 3A for a parked vehicle 2, and a tray 4 that has already been prepared is placed inside the boarding room 1. The driver of the parked vehicle leaves the boarding room 1 after stopping the parked vehicle 2 that has entered through the entrance 3 at a predetermined position on the tray 4. Thereafter, the parked vehicle 2 mounted on the tray 4 is transported to and stored in an underground storage space using, for example, a lifting device.

Inside the passenger compartment 1, as shown in FIGS. 1 and 3, there is a first height direction detection device 5 for detecting a protrusion of the parked vehicle 2 on the front side that exceeds a permissible value in the height direction; As shown in FIGS. 1 to 3, a second height direction detection device 6 is arranged to detect a protrusion of the parked vehicle 2 on the rear side that exceeds a permissible value in the height direction.

The first height direction detection device 5 faces support columns 7A and 7B distributed on both sides of the front side of the tray 4 and the parked vehicle 2, and faces the support columns 7A and 7B at a predetermined height position, respectively. When the light emitting part 8A and the light receiving part 8B are installed in such a way that the beam 9 between the light emitting part 8A and the light receiving part 8B is blocked in the height direction on the front side of the parked vehicle 2, the tolerance value in the height direction is exceeded. It is configured to include an abnormality detection section and the like that detect the presence of the protrusion 13 .

The second height direction detection device 6 faces support columns 10A and 10B distributed on both sides of the rear side of the tray 4 and the parked vehicle 2, and faces the support columns 10A and 10B at a predetermined height position, respectively. When the light emitting part 11A and the light receiving part 11B installed in such a manner interrupt the beam 12 between the light emitting part 11A and the light receiving part 11B in the height direction on the rear side of the parked vehicle 2, the permissible value in the height direction is exceeded. It is configured to include an abnormality detection section and the like that detect the presence of the protrusion 13.

Here, the height and position of each beam 9, 12 are determined during a series of movements in which the parked vehicle 2 mounted on the tray 4 is transported using an elevating device and stored in a storage space. It is selected so that it can be detected that the protruding object 13 of the vehicle 2 protrudes beyond a permissible range in which it does not collide with or come into contact with a fixed structural member or the like on the mechanical parking device side. The protrusion 13 of the parked vehicle 2 is assumed to be, for example, a decorative component attached to the rear side of the parked vehicle 2.

Depending on the identification of the protrusion 13 on the side of the parked vehicle 2 to be detected, the first height direction detection device 5 disposed on the front side of the parked vehicle 2 may be omitted. In addition, when the parked vehicle 2 that has been boarded up to the top of the tray 4 reaches a predetermined stop position, a height direction detection device 5 is used to detect abnormal protrusion at both longitudinal ends and widthwise ends of the parked vehicle 2. , 6 may be configured in the vicinity of the height direction detection devices 5 and 6, and this position detection device and the abnormality detection parts of the height direction detection devices 5 and 6 may be linked. can.

When the driver of the parked vehicle 2 parks using the above-mentioned mechanical parking device, he drives the parked vehicle 2 from the entrance 3 of the boarding room 1 onto the tray 4, and then drives the parked vehicle 2 onto the tray 4. Stop at the specified position.

At this time, the first height direction detection device 5 configured on the front side of the parked vehicle 2 irradiates the beam 9 between the light emitting section 8A and the light receiving section 8B. Further, the second height direction detection device 6 configured on the rear side of the parked vehicle 2 irradiates a beam 12 between the light emitting section 11A and the light receiving section 11B.

Therefore, as shown in FIG. 3, when a decorative component, which is an upwardly protruding object 13, is attached to the rear side of the parked vehicle 2, the second height direction detection device 6 detects that the beam 12 is caused by this decorative component. We are monitoring whether the light is blocked or not. When the decorative component does not exceed the permissible value in the height direction, the abnormality detection section of the second height direction detection device 6 does not detect an abnormality.

However, when a decorative component, which is an upwardly protruding object 13, is attached to the rear side of the parked vehicle 2, and the decorative component exceeds the permissible value in the height direction, the second height direction detection device In a mechanical parking device in which the parking lot 6 is not installed, the parked vehicle 2 is transported from the boarding room 1 to the storage space.

FIG. 4 is a side view showing the vicinity of the parked vehicle at this time for convenience.

As shown in the figure, since the protruding part 13 such as a decorative part attached to the rear side of the parked vehicle 2 exceeds the permissible value in the height direction, the fixed structural member 13 such as the corner cut of the mechanical parking device There is a risk that the protruding object 13 may collide with or come into contact with the decorative parts, damaging the decorative parts.

As described above, in the parked vehicle 2 equipped with such decorative parts, the beam 12 of the second height direction detection device 6 shown in FIGS. 1 to 3 is blocked. The second height direction detection device 6, although not shown in detail, includes an abnormality detection section that captures the light blocking signal of the beam 12, and an abnormality notification section that notifies the driver when the abnormality detection section detects the light. When the abnormality detection section captures the light blocking signal of the beam 12, the abnormality notification section notifies the driver of the abnormality while the driver is in or near the parked vehicle 2. This abnormality notification is notified to the driver by, for example, an alarm or voice from a speaker placed nearby, or an emphasized display.

Thereby, the driver of the parked vehicle 2 can take measures such as removing the decorative part or abandoning parking, and as a result, damage to the decorative part can be prevented.

Note that the specific configurations of the first height direction detection device 5 and the second height direction detection device 6 described above are not limited to those shown in the drawings, and may be adopted. Further, the present invention can be applied to various mechanical parking systems such as a vertical circulation system, an elevator system, a multilayer circulation system, and a horizontal circulation system.

As explained above, the present invention provides a mechanical parking device that transports and stores a parked vehicle 2 that has been loaded into a boarding compartment 1 into a storage space, in which parking devices are distributed at least on both sides of the rear side of the parked vehicle 2. The light emitting part 11A and the light receiving part 11B are attached to face each other at a predetermined height position, and when the beam 12 between the light emitting part 11A and the light receiving part 11B is blocked in the height direction on the rear side of the parked vehicle 2, the height is increased. The present invention is characterized in that it is provided with a height direction detection device 6 having an abnormality detection section that detects the presence of a protrusion 13 that exceeds a permissible value in the width direction.
