BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multilevel parking system that allows vehicles to be parked in two levels, upper and lower.

0002

[Prior Art] A conventional multilevel parking system was developed in 1986.
As disclosed in Japanese Patent No. 02365, the floor of the upper parking section and the floor of the lower parking section are both moved vertically in parallel to move vehicles into and out of the respective parking sections.

0003

In the conventional structure as described above, it is necessary to excavate the ground in the shape of a rectangular parallelepiped to create a space for parallel movement and descent of the lower parking section. When excavating the ground, the larger the excavation volume, the more cost and effort it takes, so conventional multilevel parking systems have the disadvantage of increasing construction cost and time. Further, if the excavation is made too deep, there will be a lot of moisture and it will be easy for the excavation to flood, so a shallower excavation is preferable, but if the excavation is made too shallow, it becomes difficult to get in and out of the parking area on the upper level. The present invention is proposed to solve this dilemma.

0004

[Means for Solving the Problems] Therefore, in the present invention, in order to reduce the amount of ground excavation than before, instead of vertically moving parallelly, the other end is moved around a horizontal axis provided in one part. In addition to having a structure that swings up and down, the floor surface of the upper parking area is divided into two parts, front and back, and the front part is configured to be able to swing forward and downward relative to the rear part. That is, in a multi-story parking system having a two-level parking structure including an upper level parking area and a semi-underground lower level parking area, the parking structure is swung around a first horizontal axis provided on a fixed foundation. The upper parking area is divided into two parts, a front part and a rear part, above the position of the windshield of a vehicle to be parked in the lower parking part, and the front part is configured to be separated from the rear part. The parking lot includes a second horizontal shaft that swingably supports the vehicle, a drive means that moves the front section up and down, and a steel cable that connects the front section and the lower parking section. Also,
The parking structure section is swingably supported by a first horizontal shaft provided on a fixed foundation, and the upper parking section is mounted in front at a position above the windshield of a vehicle to be parked in the lower parking section. and a rear part, and a second horizontal shaft that supports the front part so as to be able to swing from a substantially horizontal state to a downwardly tilted state with respect to the rear part, and a movable slope, which is connected to the front part. a third horizontal shaft that is swingably supported from a substantially upright state to a forwardly lowered state with respect to the front part, a drive means that moves the front part up and down, and a support that is erected above the movable slope. , and a steel cable that passes through a pulley provided at the front portion and connects to the lower parking portion. Further, the upper parking section may include a block member that can be attached or detached at a desired position.

[0005]

[Operation] According to the present invention having the above structure, the vehicle in the upper layer is taken in and taken out as follows. Vehicles can be easily taken in and out of the upper parking area by tilting the two-tier multilevel parking structure downward and forward using a driving means and lowering the front part of the upper parking area to match the height of the approach road surface. At this time, even if the front part is lowered, the bonnet part in front of the windshield of the vehicle in the lower parking area is low, so the front part will not come into contact with the vehicle. When loading or unloading a vehicle on the lower level, the front part of the upper level parking area is lifted by the driving means, and the entire two-level multilevel parking structure is tilted forward upward, thereby raising the floor surface of the lower level parking area. By adjusting the height to the approach road surface, vehicles in the lower parking area can easily enter and exit. At this time, since the front part of the upper parking part is lifted, the entrance part of the lower parking part is wide open. Therefore, when a vehicle on the lower floor is taken in or out, it does not come into contact with the front part of the upper parking section. In addition, since the front part and the lower parking part are connected by a steel cable, when the front part is moved up and down by the driving means, the lower parking part also moves up and down accordingly. Also,
The front part is pivotally supported by a second horizontal axis so as to be swingable from a substantially horizontal state to a downwardly tilted state relative to the rear part, and a movable slope is supported relative to the front part of the front part by a third horizontal shaft. Since it is supported so that it can swing from an almost upright position to a tilted forward position,
When the movable slope is upright, it becomes a safety guard to prevent vehicles in the upper parking area from jumping out, and when the movable slope is tilted forward and downward, the approach road and the upper parking area are connected, making it easier to enter. At this time, the pillar installed above the movable slope was connected to the lower parking section by a steel cable through the front pulley, so that the movable slope could be raised and lowered by simply raising and lowering the front part using the drive means. The lower parking area can be moved up and down. In addition, by fixing the block member at a desired position in the upper parking area, even if the shape or minimum ground clearance of the vehicle parked in the upper level is different, the vehicle will not be pushed too far into the parking area. Never rub. That is, the block member enables the function of blocking the vehicle and the function of delicately adjusting the shape of the floor surface of the upper parking area.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A multilevel parking system according to the present invention will be explained in detail below based on drawings showing embodiments thereof. FIG. 1 is a side cross-sectional view of the multilevel parking apparatus according to the present invention in a state in which it is taken in and taken out of a lower level parking area, and FIG. 2 is a side cross sectional view in a state in which it is taken in and out of an upper level parking area of the multilevel parking apparatus.

In the drawings, 1 is an upper parking pallet; 2 is an upper parking pallet;
is a lower parking pallet; 1A is a swing plate that can swing freely forming the front part of the upper parking pallet 1;
is supported by 1C is a movable slope supported by the third horizontal shaft 15 at the tip of the swing plate 1A. Above upper parking pallet 1 and lower parking pallet 2
The two-tier parking unit 5 is configured as follows. In the two-tier parking unit 5, the rear part of the upper parking pallet 1 is supported by a support 6 relative to the lower parking pallet 2, and has a "U"-shaped structure that is fixed to each other. The two-tier parking unit 5 itself is swingably supported by a first horizontal shaft 9 with respect to a fixed foundation 8. A hydraulic cylinder 7 is provided between the point of action 71 of the swing plate 1A and the foundation 81 of the underground pit 11. The hydraulic cylinder 7 is rotatably supported at these points of action 71 and the base portion 81. A wire rope 72, one end of which is fixed to a support post 16 erected near the third horizontal axis 15, passes through a pulley 18 provided on the swing plate 1A and is fixed to the lower parking pallet 2. There is. This movable slope 1C
The range of rotation relative to the swing plate 1A is limited to a range from a vertical state to a substantially horizontal state by a column 16 erected on the upper side and a stopper 19 provided on the back side of the swing plate 1A. . The underground pit 11 is dug about 50 cm below the level of the approach path 12 so that the lower part of the lower parking pallet 2 can be buried therein. Even if this underground pit 11 is not shaped into a rectangular parallelepiped with a depth of about 50 centimeters or has a shape with an inclined bottom surface, the amount of excavation will be reduced. For example, the deepest part of the underground pit 11 may be about 70 cm, and the shallowest part may be about 10 cm, and in either case, the excavation amount may be a fraction of the conventional amount. Naturally, two-tier parking unit 5
Also, the shape and dimensions of the underground pit 11 are preferably designed according to the shape and size of the type of vehicle to be parked.

FIG. 1 shows the two-tier parking unit 5 in a lifted state. When the two-tier parking unit 5 is in the forward-down position, when moving a vehicle in or out of the lower tier,
Lift up the two-tier parking unit 5 as shown below. That is, when the hydraulic cylinder 7 is operated, the swing plate 1A begins to rise. Then, the loosened wire rope 72 becomes tensed, and the movable slope 1C begins to rotate about the third horizontal shaft 15. Since the movable slope 1C stops rotating at the position where the support column 16 contacts the upper side of the swing plate 1A, when the hydraulic cylinder 7 is extended further, the wire rope 72 begins to lift the lower parking pallet 2. In this way, both the upper parking pallet 1 and the lower parking pallet 2 rotate about the first horizontal shaft 9, and the front part of the lower parking pallet 2 rises. Then, when the level of the approach path 12 and the level of the entrance of the lower parking pallet 2 match, the upper limit switch is activated and the hydraulic cylinder 7 is stopped. In this way, the height of the entrance to the lower parking area is ensured, making it easier for vehicles B to enter and exit the lower parking area.

FIG. 2 shows the two-tier parking unit 5 in a lowered state. When the front part of the two-tier parking unit 5 is raised, when a vehicle on the upper tier is to be taken in or out, the two-tier parking unit 5 is lowered as follows. That is, when the hydraulic pressure return valve of the hydraulic cylinder 7 is opened to release the hydraulic pressure, both the upper parking pallet 1 and the lower parking pallet 2 rotate about the first horizontal shaft 9, and the lower parking pallet 2 rotates. The front part comes down. When the lower parking pallet 2 hits the underground pit 11, the tension in the wire rope 72 loosens slightly and the swing plate 1A begins to lower. Then, the movable slope 1C rotates around the third horizontal axis 15 and the front begins to lower, and when the tip of the swing plate 1A matches the level of the approach path 12, the lower limit switch is activated. , the hydraulic pressure return valve of the hydraulic cylinder 7 is closed and the contraction of the hydraulic cylinder 7 is stopped. At this time, the stopper 19 is attached to the swing plate 1A.
It is in contact with the back side of. In this way, the swing plate 1A and the approach path 12 form a continuous slope, making it easier for the upper vehicle A to enter and exit. The length of the movable slope 1C is preferably about 30 to 50 centimeters depending on the installation conditions, since if it is too long, it will affect other parts.

As shown in FIGS. 1 and 2, the upper parking pallet 2 has a plurality of block members 10 arranged in two rows. By doing this, the rear wheels ride on this block member 10 when the vehicle is put in or taken out, so that the floor of the vehicle does not rub against the second horizontal shaft 4. Additionally, a block member may be provided to stop the vehicle from going too far into the vehicle. The shape, position, and number of these block members 10 are adjusted according to the height of the floor and the length of the wheel base of the vehicle parked on the upper parking pallet. As mentioned above, the driving means is not limited to a hydraulic cylinder, but it goes without saying that a rotating screw and a nut threaded thereon, or a chain drive may also be used. Further, reinforcing ribs 13 are provided to reinforce each floor surface, and for further reinforcement, it is preferable that the floor surface of the portion that does not affect the opening and closing of the driver's seat door is made into a truss structure. In addition, since the pit is shallow compared to conventional structures, there is less moisture, preventing parked vehicles and equipment from rusting, and reducing water ingress. It will be more comfortable to use if it is equipped with a drainage system to remove inundating water. Also, instead of the wire rope 72, a chain or the like may be used. Furthermore, it is safer to provide wheel stops on the lower floor to prevent the vehicle from backing up too much and from moving when the floor surface is inclined. It is also possible to operate the hydraulic cylinder 7 by remote control. In addition, a complete roof may be provided. Alternatively, the two-story parking unit 5 may be installed on the ground surface without excavating an underground pit, and a slope may be provided on the approach road. In particular, when installing a plurality of multilevel parking devices, it is preferable to install them side by side on the ground surface without excavating the ground, and to provide a common approach slope.

[0011] In this way, according to this multi-level parking system, the amount of excavation required to provide an underground pit can be reduced to a fraction of the conventional amount, so construction costs can be reduced, and reinforcing members for the walls of the underground pit can be reduced. Since only a small amount is required, it is possible to provide a multilevel parking device at a low price.

0012

[Effects] According to the present invention, only a fraction of the amount of excavation is required when installing a conventional semi-underground multi-level parking system, so construction costs can be reduced and the number of reinforcing materials for the walls of underground pits can be reduced. It is also possible to install a multilevel parking system at a low cost. Furthermore, since the multilevel parking system of the present invention does not require a shallow underground pit, it can be installed anywhere, and can be easily installed not only for commercial purposes but also for private residences.
