Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a three-dimensionally structured multi-storey parking system for dealing with a shortage of parking lot land.

[0002]

2. Description of the Related Art Conventionally, as this type of three-dimensional parking system,
It is common to lift or tilt the parking table. Among them, the one that simplifies the power system and realizes the minimum necessary device space is, for example, the actual open sho 6
No. 0-14384.

In this prior art, a two-stage parking table was lifted and lowered by a jack, and the parking table was tilted by a rotating means to allow a vehicle to be loaded and unloaded.

[0004]

However, in the above-described multi-dimensional parking apparatus according to the prior art, a large force (driving force) is required to change the inclination angle. Therefore, if the drive system fails, the user side , I could not take any measures. That is, when the drive system fails, operating the device by a manual drive means that complements it is effective as a countermeasure against the failure, but the drive system in the above-mentioned prior art can change the tilt angle as described above. Since it requires a large amount of power, there is a problem that it is not possible to provide a manual supplementary function and the vehicle cannot be put in and out when a failure occurs.

Another drawback of the prior art is that when a fixed fulcrum is rotated as an axis, the tilt angle of the table becomes too steep, and the tilt angle is suppressed within a range where the vehicle's climbing ability and bumper are not rubbed. The point is that you have to increase the length of the table.

In view of the above problems, the present invention reduces the load applied to the drive system and allows the vehicle to be manually loaded and unloaded even in the event of a failure, saving space in the device and loading and unloading the vehicle. It is an object of the present invention to provide a multi-level parking device designed to enhance flexibility.

[0007]

In order to achieve the above object, a multi-level parking apparatus according to the present invention has a parking table integrally formed in upper and lower two stages, and a tilt angle of the parking table is generated by power. Table tilting means including tilt varying means for varying the tilting angle and slide means for sliding the parking table following the operation of the tilt varying means.

[0008]

Therefore, the upper and lower parking tables can be slid and inclined according to the operation of the table elevating means to freely set the loading / unloading state. The table elevating means is provided with a tilt varying means and a sliding means for slidingly tilting the parking table, and its operation is smoothly performed with a necessary minimum force. Therefore, the table is manually driven. The device can also be operated by the means, and the moving space is small, so that the device can be constructed in a small space.

[0009]

Embodiments of the present invention will be described below with reference to the drawings.

In FIGS. 1 and 2, the multi-story parking apparatus 1 is shown.
Is basically configured to include a parking table 2, a drive device 3, and a table lifting device 4, and is configured to move vehicles 6 and 7 into and out of a road surface 5. ..

The parking table 2 has a two-stage structure in which, for example, an upper table 10 and a lower table 11 are integrally formed via a connecting member 12, and each table 10,
Top end portions 10a, 11a and rear end portions 10b, 1 of 11
Stoppers 13a to 13d are provided on 1b. The tip portion 10a of the upper table 10 on one side is bent at a predetermined angle upward from the reference surface of the table, and a contact portion 15a for contacting the road surface 5 is formed at the end portion thereof. ing.

The tip portion 11a of the other lower table 11 is bent downward at a predetermined angle below the reference surface of the table, and its end portion comes into contact with the road surface 5b. Are formed. The tip portions 10a and 11a of the tables 10 and 11 are set so as to face the end of the road surface 5 at the vehicle leaving state position, and the contact portions 15a, 11a at the vehicle leaving state position.
15b comes into contact with the end of the road surface 5 to reduce the load on the device and stabilize the operation.

The driving device 3 is for giving a driving force to a table lifting device 4 which will be described later. For example, a single-acting cylinder 20, a hydraulic pipe 21, and a reversible electric pump 22.
A hydraulic control basically composed of a bidirectionally driven motor 23, a reversible rotation circuit 24 for controlling forward / reverse rotation of the motor 23, switches 25a and 25b for forward / reverse rotation, and an oil tank 26. The circuit is composed of a switch 25a,
When either one of 25b is turned on, start-up is started, the motor 23 is rotated in the normal direction or the reverse direction, oil is pumped or sucked by the electric pump 22, and thus the rod 20a of the cylinder 20 is moved forward or backward. Table lifting device 4
Is designed to operate.

The driving device 3 is complementarily provided with a one-way valve 28, a manual pump 29 and a manual opening / closing valve 3.
And a manual drive circuit 31 of zero.

The one-way valve 28 serves as a variation regulating means for regulating a sudden load variation, and when a negative pressure is generated in the cylinder 20 due to a shock when the vehicle is in and out or a sudden load variation occurs. The cylinder 20 has a function of preventing air from being sucked into the cylinder 20 and also exerts a braking force (brake action) when the parking table 2 is angularly displaced.

The manual drive circuit 31 is provided when the electric pump 22 and the motor 23, which are basic drive systems of the drive device 3, fail.
The drive device 3 can be manually operated. When the rod 20a of the cylinder 20 is moved forward, the manual pump 29 is manually operated to pump oil and
When the zero rod 20a is retracted, the manual opening / closing valve 30 is opened to drain the oil, and the force of the load (vehicle weight) is used to return the oil. As a result, even if the basic drive system fails, the table lifting device 4 described below can be freely operated by manual operation.

The table lifting device 4 is used for the parking table 2.
Is slid and tilted to alternately set the upper and lower tables 10 and 11 to the loading / unloading position (garbage loading / unloading angle). Basically, the turning mechanism 40, the tilt varying mechanism 41, and the sliding mechanism 42 are used. Is configured.

The rotating mechanism 40 is for converting the driving force from the driving device 3 into a rotational force and transmitting the rotational force to the tilt varying mechanism 41 described below, and for example, the tip of the rod 20a of the cylinder 20. Connecting rod 45 fixed to the portion, a connecting lever 48 having a sliding groove 47 in which the connecting rod 45 is slidably fitted, and a base end portion of the connecting lever 48 are rotatably supported. It is composed of a rotary shaft 49.

The rotary shaft 49 is rotatably fixedly supported by a support, and a supporting rod 50 of a tilt varying mechanism 41 described below is fixed. When the rod 20a of the cylinder 20 is moved forward, the rotating mechanism 40 having such a structure rotates the connecting lever 48 clockwise around the rotating shaft 49, and retracts the rod 20a of the cylinder 20. The connecting lever 48 is rotated counterclockwise, and the rotating shaft 49 is bidirectionally rotated by rotating the connecting lever 48, and the rotational force of the rotating shaft 49 is transmitted to the support rod 50. To do.

The tilt variable mechanism 41 is for changing the tilt angle of the parking table 2, and is provided, for example, on a support rod 50 integrally fixed to the rotary shaft 49 and a tip portion of the support rod 50. The tilt variable rod 51 and locking members 52a and 52b for loosely fitting and locking the tilt variable rod 51 are provided.

In the tilt variable mechanism 41, when the rotary shaft 49 is rotated clockwise, the support rod 50 is rotated clockwise (lifted upward) following the rotation of the rotary shaft 49. The tilt angle of the parking table 2 is displaced counterclockwise in the figure by the tilt variable rod 51 with a slide auxiliary roller described below as a fulcrum.

On the other hand, when the rotary shaft 49 is rotated counterclockwise, the support rod 50 is rotated counterclockwise (lowered) following the rotation of the rotary shaft 49, The inclination angle of the parking table 2 is displaced in the clockwise direction in the figure with a slide auxiliary roller described below as a fulcrum.

The slide mechanism 42 slides the parking table 2 back and forth following the operation of the tilt varying mechanism 41. For example, a slide assist roller 55 rotatably supported by a support plate 53, Lower table 1
1, and a slide guide member 56 that guides and regulates the rotation of the slide auxiliary roller 55.

The slide mechanism 42 is a variable tilt mechanism 4
If the operation of 1 displaces the parking table 2 upward (counterclockwise), the parking table 2 is slid forward (right side in the drawing) with the slide auxiliary roller 55 as a reference following the operation. To go. On the other hand, if the operation of the tilt variable mechanism 41 is such that the parking table 2 is displaced downward (clockwise), the parking table 2 is moved backward (see the figure) based on the slide auxiliary roller 55 following the operation. Slide it to the left).

Next, an example of use and operation of the multi-story parking apparatus 1 having the above-mentioned structure will be described with reference to FIGS. 1 to 4.

FIG. 3 is a state diagram when the upper table 10 is set to the warehousing position and the lower table 11 is set to the unloading position, in which oil is pumped to the cylinder 20 of the drive unit 3 and the rod 20a. Is in the first position, which has been advanced. Therefore, assuming that the vehicle has not been carried in (stored) in the multi-story parking apparatus 1 at the present moment, the procedure of carrying in and out (carrying in and out) of the vehicle and the operation of the apparatus will be described below.

To carry in the vehicle, first, the lower table 11
In. The vehicle 7 drives backward from the tip 11a side of the lower table 11 facing the road surface 5 in the direction of departure and stops at approximately the center of the table. As a result, the vehicle 7 is stored in the lower table 11.

Next, in order to carry the vehicle into the upper table 10, the switch 25a of the driving device 3 is closed and a command for switching the upper and lower tables is given to the multi-level parking device 1.

Upon receiving this command, the multi-storied parking system 1 reversely operates the motor 23 and the electric pump 22 of the drive device 3 to drain oil from the cylinder 20 and retract the rod 20a. When the rod 20a is retracted, the connection lever 48 of the table lifting device 4 and the support rod 5 are accompanied by this.
Since 0 is rotated counterclockwise, the tilt angle of the parking table 2 is displaced clockwise downward with the tilt variable rod 51 as the displacement center, as shown in FIG.
It slides rearward through the slide assist roller 55, and slides rearward and tilts clockwise (downward) at the same time.

This process will be described with reference to the drawings. The parking table 2 in the state shown in FIG. 3 becomes parallel during the slide inclination, and further advances from this point, and as shown in FIG. 1, the tip portion 10a of the upper table 10 is shown. Reaches the end of the road surface 5 and is stopped in a state in which the locking portion 15b of the tip end portion 10a is locked to the road surface 5 and is in the second position.

In the state shown in FIG. 1, the vehicle can be carried into the upper table 10, and the vehicle 6 is
Tip part 10a of the upper table 10 facing the road surface 5
Drive from the front in the direction of entry from the side, and stop at approximately the center of the table. As a result, the vehicle 6 is stored in the upper table 10.

In addition, when the entered vehicle is to be unloaded, after the vehicle 6 on the upper table 10 is unloaded,
The switch 25a is closed to give a command to switch the upper and lower tables to the multi-level parking apparatus 1. In addition, the upper table 10
Alternatively, the vehicle 6 located in may be stored as it is.

In response to this command, the multi-storied parking system 1 causes the motor 23 and the electric pump 22 of the drive system 3 to operate in the normal direction in the cylinder 20 so as to be in the same state as the lower table loading / unloading state (see FIG. 3). Oil is pumped and the rod 20a is advanced. When the rod 20a is advanced, the connecting lever 48 and the support rod 50 of the table lifting device 4 are rotated in the clockwise direction accordingly, so that the parking table 2 has the tilt variable rod 51 as the displacement center. As the tilt angle is displaced upward (counterclockwise), it slides forward through the slide assist roller 55, and the forward slide and the upward tilt are performed simultaneously.

This process will be described with reference to FIG. 4, which is the reverse of the above-described warehousing process, and the parking table 2 is in a parallel state during the slide inclination, and the process further proceeds from FIG.
As shown in FIG. 5, the tip 11a of the lower table 11 reaches the end of the road surface 5, and the locking portion 15a of the tip 11a is stopped in a state of being locked to the road surface 5. In the state shown in FIG. 1, the vehicle can be carried out from the upper table 10.

Hereinafter, the changeover switches 25a and 25b are appropriately used.
You can freely move the vehicle in and out by operating.

Here, in a normal state where the basic drive system (motor 23, electric pump 22 and the like) of the drive unit 3 operates normally as described above, as shown in FIG. As a general rule, the vehicle 6 to be stored is parked in the direction of ship entry, and the vehicle 7 to be stored in the other lower table 11 is in the direction of ship departure. The reason is that the slide assist roller 55, which serves as a fixed contact, holds the load of the vehicle 6 on the upper table 10 and the vehicle 7 on the lower table 11.
This is because the balance is centered around. As a result, the load on the drive device can be reduced.

Further, the vehicle 7 stored in the lower table 11 is set and parked in the direction of departure, that is, when the vehicle 7 is in the leaving state, the inclination angle of the lower table 11 is directed upward. Therefore, the visibility of the road surface 5 is narrowed. If the vehicle 7 is unloaded from the back in this narrow field of view, there is a great risk of causing an accident,
This is because it is necessary to set and park the boat in the direction of departure to ensure maximum visibility. Even if this principle is neglected in the multilevel parking apparatus 1, the one-way valve 28 provided in the drive unit 3 adapts to the negative pressure and exerts a braking function, so that danger is avoided and safety is improved. It is designed to be kept.

Next, the function of the user when the multi-level parking device 1 is out of order will be described.

As described above, in the multi-level parking apparatus 1, assuming that the basic drive system (electric pump 22, motor 23, etc.) of the drive apparatus 3 fails, the multi-level parking apparatus 1 will be described.
Is provided with a manual drive circuit 31 for manually operating. Other drive systems (cylinder 20, hydraulic pipe 21
It is not necessary to give special consideration to the failure of () and the like) because it is relatively unlikely to occur empirically, but it must be placed at a position where the vehicle etc. does not hit.

When the basic drive system fails, if there is only one vehicle on the parking table 2 and the table in which it is stored is in the exitable position, the multilevel parking system 1 can be operated without any operation. Although the vehicle can be taken out, it is necessary to change the tilt angle of the parking table 2 by the manual drive circuit 31 if the table in which the vehicle is stored is not at the leaving position.

When the inclination of the parking table 2 is opposite to the side where the user wants to leave the vehicle, and the vehicle 6 on the upper table 10 is desired to be left, the manual opening / closing valve 30 is opened so that the inside of the cylinder 20 is closed. Oil can be drained, whereby the rod 20a of the cylinder 20 can be retracted by the load of the vehicle, and the upper table 10 can be brought into the leaving position (second position) (FIG. 3 → FIG. 1).

When the inclination of the parking table 2 is opposite to the side where the user wants to leave the vehicle and the vehicle 7 on the lower table 11 is desired to be left, the manual pump 29 is manually driven to move the inside of the cylinder 20. A hydraulic pressure can be applied to the rod 20a to move the rod 20a forward so that the lower table 1
1 can be set to the leaving position (first position) (FIG. 1 → FIG. 3).

At this time, when the vehicle 6 is stored in the upper table 10 and the principle of the entry direction of the vehicle 6 is observed, the vehicle 6 of the upper table 10 is generally Balanced, so manual pump 2
The load that must be operated at 9 is the parking table 2
And the center of gravity of the vehicle 7 in the lower tier deviate from the slide auxiliary roller 55, which is a fixed contact, and the horizontal component force for climbing the entire weight of the vehicle 6 in the upper tier at a slight angle. Since this load is not too much, it is sufficient to deliver the hydraulic pressure by the manual pump 29 in order to process this load with the present device 1 having the slide tilting mechanism that moves the center of rotation by sliding.

Therefore, the vehicle 6 is placed on the upper table 10.
Even if the table has been stored, the lower table 11 can be set to the leaving position as it is. Although the embodiment is composed of a bidirectional drive motor and a reversible electromagnetic pump, the same operational effect can be achieved by a unidirectional drive motor and an electromagnetic valve. Also, the hydraulic cylinder 2
By supporting the base part of 0 by the rotating shaft, the sliding groove 47 can be made into a single hole.

However, when the upper vehicle 6 is parked in the direction of departure, a relatively large force is required to change the inclination of the parking table 2. Therefore, the upper vehicle 6 is first discharged. Or the manual pump may have to be manually operated by a relatively powerful person.

Next, another embodiment of the multilevel parking system 1 will be described with reference to FIG. However, the same components as those of the multi-level parking device 1 according to the first embodiment described above are denoted by the same reference numerals and the description thereof will be omitted, and only different points will be described below.

The other embodiment is different from the first embodiment in that the drive unit 3 is constituted by a chain drive unit.

This chain drive device comprises, for example, a chain 60 wound in a belt shape, a drive sprocket 61 for rotating the chain 60, a support sprocket 62, and a motor for giving a drive force to the drive sprocket 61. It is configured by a control device (not shown), and for example, a ring-shaped connector (not shown) is provided on a part of the chain 60.
Is provided, and this is fixed to the connecting rod 45, and the connecting lever 48 is rotated in accordance with the movement of the chain 60. In this drive system as well, the connection lever 48 is rotated by the movement of the chain 60, and the parking table 2 is appropriately slid and tilted in the same manner as in the above-described embodiment, so that the vehicle can be loaded and unloaded.

The manual drive device provided in the drive device 3 may be, for example, a gear mechanism. Specifically, for example, as shown in FIG. 5, the manual drive device 65 includes a worm gear 66 directly connected to the drive sprocket 61, a worm wheel 67 meshing with the worm gear 66, and a manual drive connected to the worm wheel 67. The worm wheel 6 is configured by rotating the manual rotation handle 68 with the rotation handle 68.
7. The drive sprocket 61 is rotated via the worm gear 66, the chain 60 is moved accordingly, the connecting lever 48 is rotated, and the parking table 2 can be appropriately slid and inclined. When operating the manual drive device 65, it is necessary to disconnect the drive sprocket 61 and the drive control device via a clutch or the like. Also,
By disposing a gear mechanism that amplifies the driving force between the worm gear 66 and the drive sprocket 61, the force related to the operation of the manual rotation handle 68 is further reduced, and the operability is improved.

[0050]

As described above, according to the present invention,
Since the parking table is slid to switch between the upper table and the lower table, the load on the device is reduced, the device can be operated smoothly, and manual drive as a countermeasure against failure The means can be easily provided.

Further, since it is of the slide inclination type, the distance between the front and rear of the device can be minimized, space can be saved, and the device can be provided even in a relatively narrow parking lot. In addition to being capable of three-dimensional parking, it is possible to keep the ceiling height lower than that of the conventional structure, and it is possible to sufficiently secure a parking lot in a large city. Is.
