Embodiments of the present invention will be described below based on the drawings.

FIG. 1 is a front view showing a schematic configuration of a mechanical parking device according to an embodiment of the present invention.
A parked vehicle 3 that has entered the passenger compartment 2 through the entrance/exit 1 of the parking device building is loaded onto a tray 5 that is waiting on the elevating portion of the lift device 4 that is arranged so as to substantially block the lift opening.

After the driver gets off the parked vehicle 3, the lift device 4 is driven, and the parked vehicle 3 mounted on the lifting portion of the lift device 4 is transported and stored, for example, to a parking space 6 formed on a lower floor. Ru. The parking space 6 of this mechanical parking device is configured into two layers in the vertical direction by combining a plurality of vertical columns 7, cross beams 8, etc. inside the building.

The lift device 4 has four vertical columns 9 disposed on the outer periphery of its elevating portion and extending in the elevating direction, and is configured such that the elevating portion is moved up and down by a drive device 10. There is. A lift device 11 for moving between floors is configured on the opposite side of the lift device 4, and this lift device 11 for moving between floors has almost the same configuration as the lift device 4, and is driven by a drive device 12 to park between floors. The vehicle is configured to move.

As is well known, when a parked vehicle 3 is stopped on a tray 5 in the passenger compartment 2, in order to correctly stop the parked vehicle 3 at a predetermined stop position on the tray 5 so as not to interfere with subsequent transportation, there is a need to A protrusion detection device and the like for performing detection are configured. As a protrusion detection device, for example, one using a photoelectric sensor is known.

FIGS. 2 and 3 are a plan view and a side view showing the main parts of the parked vehicle 3 mounted on the lifting portion of the lift device 4 being transported to the parking space 6. FIG.

Various configurations are known as the lift device 4, but here it has vertical columns 9A, 9B, 9C, and 9D arranged near the outer periphery of the lifting portion 4A and extending substantially vertically. Each vertical column is connected in the same way as the vertical column 7 and the horizontal beam 8 at a position where there is no problem when moving the vehicle 3 from the lift device 4 to the upper and lower parking spaces 6 sides. For example, the opposing portions of the vertical columns 9A and 9B are connected by a connecting member 13A similar to the horizontal beam 8, and the opposing portions of the vertical columns 9C and 9D are also connected by a connecting member 13B similar to the horizontal beam 8.

In this type of mechanical parking device, when the parked vehicle 3 mounted on the tray 5 is transported from the boarding/exiting room 2 to the parking space 6, the lift device 4 is used. It is also conceivable that the side door or back door of the parked vehicle 3 may open due to sudden vibrations when starting or stopping the operation. Therefore, in order to detect the protrusion at this time, a new protrusion detection device is provided. Next, this new protrusion detection device will be explained.

As shown in FIGS. 2 and 3, vertical columns 9A to 9D are arranged at fixed positions relative to the parked vehicle 3 transported by the lift device 4. Although various configurations can be adopted for the vertical columns 9A to 9D, here, the space between the vertical columns 9A and 9B at both longitudinal ends of the parked vehicle 3 is located at a position that does not hinder the vertical movement of the tray 5. The vertical columns 9C and 9D are connected by a connecting member 13A that is connected, and the vertical columns 9C and 9D are connected by a connecting member 13B that is connected at a position that does not hinder the vertical movement of the tray 5.

Using such vertical columns 9A to 9D, photoelectric sensors constituting the protrusion detection device are respectively attached. Specifically, a light-emitting side photoelectric sensor 14A is attached near the part of the vertical column 9A facing the vertical column 9B, and a light-receiving side photoelectric sensor 14B is attached near the part of the vertical column 9B facing the vertical column 9A. The light emitting side photoelectric sensor 14A and the light receiving side photoelectric sensor 14B constitute one width direction protrusion detection device 14.

Similarly, a light-emitting side photoelectric sensor 15A is attached near a portion of the vertical column 9B facing the vertical column 9C, and a light-receiving side photoelectric sensor 15B is attached near a portion of the vertical column 9C facing the vertical column 9B. The other width direction protrusion detection device 15 is constituted by the light emitting side photoelectric sensor 15A and the light receiving side photoelectric sensor 15B.

Further, a light emitting side photoelectric sensor 16A is attached near the part of the vertical column 9C facing the vertical column 9A, and a light receiving side photoelectric sensor 16B is attached near the part of the vertical column 9A facing the vertical column 9C. One height direction protrusion detection device 16 is constituted by the light emitting side photoelectric sensor 16A and the light receiving side photoelectric sensor 16B.

Similarly, a light-emitting side photoelectric sensor 17A is attached near a portion of the vertical column 9D facing the vertical column 9B, and a light-receiving side photoelectric sensor 17B is attached near a portion of the vertical column 9B facing the vertical column 9D. The light emitting side photoelectric sensor 17A and the light receiving side photoelectric sensor 17B constitute the other height direction protrusion detection device 17.

Each of the protrusion detection devices 14 to 17 described above is configured near the passenger compartment 2 side of the lift device 4, for example, near the upper layer side of the parking space 6. Therefore, when the parked vehicle 3 is loaded and transported from the passenger compartment 2 to the parking space 6 side, even if the side door or back door of the parked vehicle 3 opens due to the impact at the start of the operation, the protrusion detection devices 14 to 17 Extrusion can be detected by blocking any light.

Further, as shown in FIG. 3, second protrusion detection devices 18 to 21 having the same configuration as the protrusion detection devices 14 to 17 described above are arranged near the lower side of the parking space 6, for example. The second protrusion detection devices 18 to 21 are arranged in the same manner as the protrusion detection devices 14 to 17 in a vertically overlapping manner, so what is illustrated in FIG. The second light emitting side photoelectric sensor 18A in the second width direction protrusion detection device 18 is arranged to correspond to the light side photoelectric sensor 14A, and the light receiving side photoelectric sensor 14B in the width direction protrusion detection device 14 is arranged so as to correspond to the second light emitting side photoelectric sensor 18A. The second light-receiving side photoelectric sensor 18B in the width direction protrusion detection device 18 and the second light receiving side photoelectric sensor 17A in the height direction protrusion detection device 21 arranged so as to correspond to the light emitting side photoelectric sensor 17A in the height direction protrusion detection device 17. There are only the light emitting side photoelectric sensor 21A and the second light receiving side photoelectric sensor 20B arranged so as to correspond to the light receiving side photoelectric sensor 16B in the other height direction protrusion detection device 16.

The above-mentioned second protrusion detection devices 18 to 21 are arranged near the stop position of the lift device 4 on the parking space 6 side, for example, near the lower side of the parking space 6. Therefore, when the parked vehicle 3 is loaded and transported from the passenger compartment 2 to the parking space 6 side, even if the side door or back door of the parked vehicle 3 opens due to vibration at the end of the operation, the second protrusion detection devices 18 to 21 It can be detected by either light blocking.

4 and 5 are a plan view and a side view showing the mounting structure of each photoelectric sensor.

Since each photoelectric sensor is attached with substantially the same configuration, the light emitting side photoelectric sensor 14A attached to the vertical column 9A will be explained here as a representative example.

A bracket 22 is fixed to the vertical column 9A on the side opposite to the vertical column 9D. This bracket 22 is integrally formed with a mounting part 22A formed along the fixed surface of the vertical column 9A and a cover part 22B formed substantially horizontally so as to cover the upper part. This cover portion 22B may be in the shape of a flat plate, or may have a shape with the end portion bent slightly downward so as to more effectively protect the light emitting side photoelectric sensor 14A from dripping rainwater from above. .

The mounting portion 22A is fixed by bolts 23 or the like in contact with the side surface of the vertical column 9A, and the light emitting side photoelectric sensor 14A is mounted on the lower surface side of the cover portion 22B using an L-shaped mounting member 24. Mounted in an adjustable position. The mounting member 24 is bent into an L-shape as a whole, and has a horizontal portion 24A that contacts the lower surface of the cover portion 22B, and a hanging portion 24B that extends downward with respect to the horizontal portion 24A. The light emitting side photoelectric sensor 14A is attached to the hanging portion 24B side.

Although detailed illustrations are omitted between the bracket 22 and the mounting member 24, and between the mounting member 24 and the light emitting side photoelectric sensor 14A, there are elongated holes extending in the horizontal direction, vertical direction, and front-rear direction, and the elongated holes. Using bolts 25, 26, 27, and 28, which are tightened and fixed inside, the light emitting side photoelectric sensor 14A is fixed so that its position can be adjusted. Therefore, the light emitting side photoelectric sensor 14A can appropriately adjust the facing relationship with the light receiving side photoelectric sensor 14B shown in FIG.

In particular, as can be seen from FIG. 5, the upper part of the light emitting side photoelectric sensor 14A attached to the bracket 22 is covered by a cover part 22B formed at the upper part thereof. Therefore, even if rainwater or the like that has adhered to the parked vehicle 3 and is brought in drips, it will be received by the upper surface side of the cover portion 22B, and the light emitting side photoelectric sensor 14A will not malfunction. Furthermore, since the cover portion 22B is integrally formed with the bracket 22, the number of parts is reduced.

Furthermore, since the light emitting side photoelectric sensor 14A can be attached to the lower surface side of the cover part 22B, the side of the light emitting side photoelectric sensor 14A facing the light receiving side photoelectric sensor 14B is open, and the position of the facing relationship described above can be adjusted. Work can be done easily.

The light-receiving side photoelectric sensor 14B opposite to the light-emitting side photoelectric sensor 14A shown in FIGS. 2 and 3 is also attached in the same way, and both photoelectric sensors 14A and 14B forming the other width direction protrusion detection device 14 and the height direction Both photoelectric sensors 16A to 17B constituting the protrusion detection devices 16 and 17 are also attached in substantially the same way.

Now, when moving the parked vehicle 3 from the boarding room 2 to the parking space 6 using the lift device 4, suppose that the right side door of the parked vehicle 3 shown in FIG. Suppose that the side door opens slightly due to the vibration caused by the device 4 when it starts moving. When such a parked vehicle 3 passes through the width direction protrusion detection device 14 including both photoelectric sensors 14A and 14B arranged oppositely in a pair, the beam between the pair of photoelectric sensors 14A and 14B is blocked. Then, the width direction protrusion detection device 14 detects the protrusion.

Based on this detection signal, the control unit of the mechanical parking device can automatically stop the lift device 4 or notify the parking lot manager. Therefore, it is possible to prevent a serious situation from occurring when the parked vehicle 3 is moved to the parking space 6. Moreover, even if rainwater brought in by the parked vehicle 3 drips, it is blocked by the cover portion 22B and protects both photoelectric sensors 14A, 14B from malfunctioning. It can be detected reliably, and the safety when the parked vehicle 3 is moved and the reliability from users can be further improved.

In addition, when the lift device 4 is used to transport the parked vehicle 3 from the passenger compartment 2 to the parking space 6, if a problem occurs due to vibration when the lift device 4 is stopped, the above-mentioned second protrusion detection device 18 .about.21 can be similarly detected.

Next, a case will be described in which the lift device 4 is used to transport the parked vehicle 3 from the parking space 6 to the passenger compartment 2 at the time of leaving the garage. In this case, the protrusion due to vibration at the beginning of the movement of the lift device 4 can be similarly detected by the second protrusion detection devices 18 to 21 described above.

Furthermore, if a problem occurs due to vibration when the lift device 4 is stopped at the same time of leaving the warehouse, it can be similarly detected by the above-mentioned protrusion detection devices 14 to 17.

In the above-mentioned embodiment, a configuration was described that can detect vibrations in the initial stage of operation of the lift device 4 and occurrence of protrusion that may occur due to vibrations when the lift device 4 is stopped. Various configurations are possible because the abnormality occurrence situation due to vibration differs depending on the configuration and usage type.

For example, if the parked vehicle 4 is only a sedan-type regular passenger car and there is no need to detect the protrusion of the back door, a configuration may be provided in which only the protrusion detection devices 14 and 15 are provided. Furthermore, if it is sufficient to detect only the protrusion that may occur due to vibrations during the initial operation of the lift device 4 when entering the warehouse, only the protrusion detection devices 14 to 17 may be provided. Alternatively, if the protrusion does not occur due to vibration in the initial operation of the lift device 4 when entering the warehouse, the protrusion may occur later when the lift device 4 is stopped, at the beginning of the operation of the lift device 4 when leaving the warehouse, or when the lift device 4 is stopped when leaving the warehouse. If it is concluded that the above does not occur, it is possible to provide only the protrusion detection devices 14 to 17 shown in FIG. 3 and omit the other second protrusion detection devices 18 to 21. Similarly, even when the parking space 6 has a three-layer structure, the position where the protrusion detection device is installed can be determined by adopting the above-mentioned concept.

Further, in the above-described embodiment, each photoelectric sensor is attached to a dedicated bracket 22, but two photoelectric sensors arranged close to each other, for example, the light-emitting side photoelectric sensor 14A and the light-receiving side photoelectric sensor 16B, are attached to a common bracket. They may be attached so that their positions can be adjusted.

Furthermore, the positions of the paired light emitting side and light receiving side of each of the photoelectric sensors 14A to 17B are not limited to those shown in the drawings.

In addition to the above-described configuration, the present invention also provides light-emitting side photoelectric sensors 14A, 15A and light-receiving side photoelectric sensors 14B, 15B, which are arranged opposite to each other at opposing portions of the vertical columns 9A to 9D located on both sides in the width direction of the parked vehicle 3. The present invention is characterized in that the protrusion detection devices are width direction protrusion detection devices 14 and 15 that detect protrusion of the side door of the parked vehicle 3 due to vibration from the lift device 4.
