There are things that cannot be wiped away. Furthermore, even if there are people on the empty horizontal parking lot 100 or the elevating parking lot 103,
These parking spaces can be moved side by side and up and down, and even if there is a person 102 in an empty parking space 104, this cannot be detected, so the up and down parking spaces 10 can be moved in this state.
It cannot be said that it is perfect as a safety device, as lowering the 3 could lead to an accident resulting in death or injury.

In view of the above-mentioned circumstances, the present invention is an apparatus for storing vehicles by moving a plurality of vehicle-mounted parking spaces by appropriate control means, in which the presence of people, etc. can be confirmed on the floor surface including the moving range of the parking spaces. A first detection means is provided, and a second detection means is provided at the parking platform or at a suitable location within the parking area and at a suitable location within the parking area, and is capable of discriminatingly confirming the presence of a person or vehicle on the parking platform; With the absolute condition of non-detection, only when the second detection means is in a non-detection state or a vehicle detection state, a control means including an emergency drive stop circuit for the entire parking equipment issues a signal from an appropriately provided safety control circuit. The purpose of the present invention is to provide a safety device for a mechanical parking facility, which aims to eliminate the risk of the aforementioned accidental injury by making the drive possible.

Hereinafter, the present invention will be explained in detail based on embodiments of the drawings. In Figures 2 and 3, 1 is a two-stage, three-row parking facility as a mechanical parking facility, which is erected at appropriate distances on the left and right, and is divided into three parking rows R1 and R2 by a pair of front and rear columns 2 and 2'. , R3, and form two upper and lower parking spaces U and D for each parking row, and the lower parking space D of each parking row R1, R2, R3.
An entry/exit entrance E is formed at the front of each.

Four wheels 6 are respectively provided on the lower surface to correspond to the rails 5 which are laid in the left and right direction at a distance from the front and back.
forward/reverse motor 7 with off-brake engaged with a and 6b and installed on the lower surface of the transverse parking platform 3a and 3b
It is possible to move horizontally by driving a and 7b.

8a, 8b, and 8c are parking rows R1 and R, respectively.
2. With the elevating parking platform located in the upper parking space U of R3, each front and rear column 2,
2' is used as a guide to move up and down between the lower parking space D and the lower parking space D by driving forward/reverse rotation motors 9a, 9b, and 9c with off-brakes installed on each front pillar 2.

LU1, LD1; LU2, LD2; LU3, LD3 are arranged at predetermined positions behind the upper and lower parking spaces U and D in the parking rows R1, R2 and R3, respectively, and act as upper limit switches for the elevating parking spaces 8a, 8b and 8c. This is a lower limit switch. Among these, the lower limit switches LD1 and LD3 can be engaged only with the transverse parking spaces 3a and 3b, respectively, and the lower limit switch LD2 can be engaged with both the transverse parking spaces 3a and 3b, and each parking row R1, It also serves as a control for rampant movement in R2 and R3.

P1a, P1b; P2a, P2b; P3a, P
3b is a vehicle detector of the second detection means, and is arranged at the rear of the lower parking space D of each parking row R1, R2, R3, at intervals slightly narrower than the width of the vehicle W, from the center to the left and right. They are a pair of direct reflection type phototubes, each of which has a built-in light emitting part and a light receiving part, and its detection ability is such that it can detect a vehicle parked at a predetermined position on the transverse parking stands 3a, 3b.
Incidentally, this phototube may be of a separated type with the emitting and receiving parts arranged one at the upper part and the other at the lower part. Further, instead of the phototube, a direct reflection type ultrasonic generator tube may be used as a similar non-contact detection means.

SF is a mat switch S3a, S3b, S8a, S3a, S3b, S8a, S3a, S3b, S8a, and
8b and S8c are the horizontal parking spaces 3a and 3, respectively.
This is a mat switch for detecting a person among the second detection means spread over the upper surfaces of the parking spaces 8a, 8b, and 8c.

These Matsuto switches SF, S3a, S3
b, S8a, S8b, and S8c are all commercially available products with the structure shown in the cross-sectional view in Fig. 4, and there is a spring pile MS3 between the flexible upper and lower plates MS1 and MS2.
A cavity MS4 is formed in a proper position, and the upper plate MS is loaded in the cavity MS4.
A pair of upper and lower conductor plates MS5 and MS6 are fixedly mounted on the lower surface of the lower plate 1 and the upper surface of the lower plate MS2 so as to face each other. However, although the spacing between the upper and lower plates MS1 and MS2 is normally maintained constant by the spring force of the spring pile MS3, and both conductor plates MS5 and MS6 are kept slightly apart to maintain a non-contact state, the upper plate When an object is placed on MS1, the upper plate MS1 bends downward against the spring force of the spring pile MS3, and at the same time both conductor plates MS5 and MS6 collide, producing a detection signal. The Matsuto switch used here is of high speed and is capable of detecting light objects such as dogs, cats, and infants.

FIG. 5 shows a safety control circuit in the two-stage, three-row parking facility 1 having the above-mentioned configuration. In this safety control circuit, upper limit switches LU1, LU2, LU
3 and lower limit switches LD1, LD2,
Both LD3 have normally open contacts, and the elevating parking platform 8
a, 8b, 8c and/or horizontal parking lot 3a,
When engaged with 3b, it closes and emits a “0” signal,
When the engagement is released, the open state is restored and a signal of "1" is generated. In addition, Matsuto Switch SF installed on the floor, Matsuto Switch S3a installed in the parking lot,
The input terminals of S3b, S8a, S8b, and S8c emit a signal of "1" when weight is detected, and the phototubes P1a, P1b; P2a, P2b; P3a, P3
The input terminal b emits a signal of "1" when shielded from light. is a relay that is energized by conduction of the transistor 25, and when the relay is energized, the emergency drive stop circuit in the drive control means (not shown) of the parking equipment 1 is deactivated, and the parking stall 3 is stopped.
a, 3b motors 7a, 7b and elevating parking platform 8
It is designed to allow each of the motors 9a, 9b, and 9c of the motors 9a, 8b, and 8c to be driven. Conversely, when the relay is in the demagnetized state, the emergency drive stop circuit operates to stop the driving of the motors 7a, 7b, 9a, 9b, 9c, apply the brakes, and activate an alarm (not shown) as appropriate. It is set to work.

Next, the operation of the two-stage, three-row parking facility 1 having the above-mentioned configuration will be explained.

Now, as shown in Fig. 2, the parking lot 3a,
3b are arranged in the lower parking spaces D of parking rows R1 and R2, respectively, and are lower limit switches LD1 and LD.
2, and also engages with the elevating parking platform 8a, 8b,
8c is arranged in the upper parking space U of parking rows R1, R2, and R3, respectively, and the upper limit switch LU
1, LU2, and LU3 are engaged. Vehicles W are mounted on the transverse parking platform 3a and the elevating parking platforms 8a, 8b, and 8c, and the transverse parking platform 3b is empty. Furthermore, it is assumed that no person or object is placed on the pit floor 4.

Therefore, in the safety control circuit shown in FIG. 5, the input terminals of the mat switches S3a, S8a, S8b, and S8c receive a "1" signal, and the input terminal of S3b receives a "0" signal. Phototube P1a, P1
Since only b is blocked by the vehicle W, a signal of "1" is input to its input terminal, and a signal of "0" is input to the input terminals of the other phototubes P2a, P2b, P3a, and P3b. There is. Parking row R
Since only the lower parking space D of No. 3 is empty, only the normally open contact of lower limit switch LD3 remains open, and the other lower limit switches LD1, LD2 and upper limit switch
The normally open contacts of LU1, LU2, and LU3 are closed.
Since the non-detection signal "0" is input to the input terminal of the mat switch SF, its inverted signal "1" is one input of the AND circuit 24. The other input of the AND circuit 24 is connected to the normally open contact of the lower limit switch LD3.
AND circuits 15a to 15d, OR circuits 21a, 21
b. Since the signal is “1” after passing through the AND circuit 22f and the OR circuit 23, the transistor 2
5 is in a conductive state. Therefore, the relay is energized by the conduction of the transistor 25, and the emergency drive stop circuit is made inactive, and from this state, it is possible to move the transverse parking spaces 3a and 3b or to lower the elevating parking space 8c.

Next, in the above-mentioned state, when the person M gets on the empty parking lot 3b, a signal of "1" is input to the input terminal of the Matsuto switch S3b, and the phototubes P2a and P2
Unless both of b are blocked at the same time,
The outputs of AND circuits 15c and 15d both become "0", and this signal is transmitted to AND circuit 22f, OR
The transistor 25 is made non-conductive through the circuit 23 and the AND circuit 24, and the relay is also demagnetized accordingly, so the emergency drive stop circuit is activated, and all the horizontal parking spaces 3a, 3b and the elevating parking spaces 8a, 8 are turned off.
B and 8c become undriveable due to the brakes being applied.
Also, no matter where the person M gets on the pit floor 4, the Matsuto switch SF detects the weight, and since a signal of "1" is input to its input terminal, the inverted signal of "0" is
Enters the AND circuit 24, and the transistor 2 as described above.
5 is disconnected and the relay is demagnetized, the emergency drive stop circuit is activated.

Furthermore, for example, in the state shown in FIG. 2, the elevating parking platform 8
If a person M gets on the empty transverse parking platform 3b or the pit floor 4 while the parking platform 8c is being lowered, the aforementioned safety control circuit immediately stops the descent of the elevating parking platform 8c, thereby preventing an accident. .

The above embodiment was explained using a two-stage, three-row parking facility.
It can also be applied to other mechanical parking facilities, such as vertical circulation parking facilities. That is, in Figure 6, 3
0 is a lower entry vertical circulation type parking facility that forms an entry/exit entrance 32 at the front surface of the lower ground of a building 31, and upper sprockets (not shown) are arranged for two each on the upper and lower sides.
Two endless chains 34 are stretched between the lower sprocket 33 and the endless chains 34, and a plurality of parking cages 36 for mounting vehicles are suspended by a connecting member 35 connected to the endless chains 34, and the parking cages 36 for mounting a plurality of vehicles are suspended by an appropriate drive source. The group of cages 36 is rotated counterclockwise or clockwise. Floor Matsuto switches 38 are spread over the entire floor 37 inside the entry/exit opening 34,
Further, the entire surface of the parking stall 36a of each parking cage 36 is also covered with parking mat switches 39.

The floor matsu switch 38 is always connected to a power source for transmission, while the parking car matsu switch 39 is equipped with a freely rotating roller 39a for power connection on the underside of the parking car 36a, and each parking car cage 36 is connected to the entrance 32 Each time it reaches a predetermined position, it comes into contact with a power supply contact plate 40 provided at the center of the floor 37 to enable detection. In addition, in order to detect the presence or absence of a vehicle W in the parking cage 36 that has reached the predetermined position, two projecting lights are provided at the rear of the entry/exit entrance 32 in parallel and spaced apart as appropriate along the vehicle entry direction.
Direct reflection type phototubes 41a and 41b are provided.

Therefore, when the parking cage 36 is stopped at the predetermined position of the entrance/exit 32, the absolute condition is that the floor matsu switch 38 does not detect the weight. Only when 41b does not detect a vehicle, or when the parking stall matsu switch 39 detects weight and both phototubes 41a and 41b detect a vehicle, a circuit (not shown) similar to the safety control circuit described above connects to the drive source. This gives permission to move the parking cage 36.

In the above embodiments, the two-stage and vertical circulation type parking facilities have been described, but the present invention can also be implemented in a single-stage planar circulation type parking facility.

Further, as a second detection means, a matsuto switch 51 placed on the parking platform 50 as shown in FIG.
At least two wheel corresponding parts 51a of the parts corresponding to each wheel at the vehicle mounting position are made independent from the non-wheel corresponding parts 51b, and the vehicle is detected using all the detection signals of these independent wheel corresponding parts 51a, Other detection signals can be similarly implemented for human detection.

As detailed above, when using the device of the present invention,
The first system to confirm the presence of a person is installed on the floor within the parking area.
A detection means and a second detection means capable of identifying and confirming the presence of a person or vehicle on each parking stall or a parking stall provided within the parking area are used to detect whether a person or the like is on the floor within the parking area or in an empty parking stall. Conventionally, when someone is riding on a vehicle or the vehicle is parked in a place other than the designated location, it is immediately detected and the control means that controls the entire parking system is restrained and stopped. This not only eliminates the risk of personal injury caused by people entering the mechanical parking facility, but also completely protects vehicles and equipment.
