Description

[Detailed explanation of the invention] A. Industrial application field This invention consists of vertically installing a pair of pillars on both left and right edges of a vehicle approach road, and horizontally extending the space along the pillars into the space surrounded by the pillars. This invention relates to an improvement in a two-tiered multi-level parking system, which is provided with a vehicle platform that moves up and down, and which secures a parking space partitioned into two upper and lower levels by the vehicle platform.

B. Conventional technology With the development of motorization, the streets are overflowing with cars, and parking lots are all full. Therefore, in order to efficiently utilize the narrow space and secure double the parking space, a two-tiered multi-level parking system is used, which secures parking space above and below by means of a vehicle platform that moves up and down.

C. Problems to be solved by the invention This type of two-tier multilevel parking system is designed to increase the number of parking spaces, and also to allow vehicles to be parked horizontally with their backs against the edge of the parking lot so that they can easily take vehicles in and out and guide them to entrances and exits. It is desirable to arrange them in a row.

However, in the conventional two-level multilevel parking system in which a pair of pillars are hung on both the left and right edges of the vehicle approach road, the pillars are located outside the space that allows vehicles to enter.
Moreover, since the distance between each pair of pillars is the same, when they are placed side by side, there will be two pillars 1 between adjacent vehicle entry spaces P and vehicle entry spaces P, as shown in Figure 6. A dead space D of equivalent width is created, and if several dozen parking systems are installed in succession, the width cannot be ignored, and the purpose of installing a two-level multilevel parking system to park as many cars as possible cannot be fully achieved. .

D. Means for Solving the Problems Therefore, the present invention aims to effectively utilize the site by halving the area of the dead space that occurs at the boundary between adjacent devices. The outer dimension L ₁ between the pair of struts is set to be equal to or less than the inner dimension L ₂ between the pair of struts vertically installed on the other side edge.

E. Effect When arranging the columns horizontally in a row with the entry sides facing the same direction, if the columns on one side of the narrower space between the columns are arranged between the columns on the other side with the wider space between the columns, the dead spaces overlap and the columns are aligned. Since the width corresponds to the duty, the difference is large when several units are installed, and it is possible to increase the number of units installed.

F. Embodiment The drawing shows a two-stage multilevel parking system according to the present invention, in which 1a, 1b, 1c, and 1d are each a pair of pillars erected on both sides of the vehicle approach direction while maintaining the vehicle approach width. The outer dimension L ₁ between the columns 1a and 1b is slightly narrower than the inner dimension L ₂ between the columns 1c and 1d. And the pillars 1a, 1 facing each other on the left and right
A cylinder 3 operated by a hydraulic unit 2 attached to the side of the support column 1c is installed between the columns 1c, 1b, and 1d.
Support beams 4, 4 that move horizontally up and down are installed, and a drive-on plate 5, which is a vehicle platform, is fixed on the support beams 4, 4, and on the entry side of the drive-on plate 5, , step 6 are successively provided. Further, the drive-on plate 5 has a belt-shaped reinforcing plate 5a in the center thereof.
are provided, and wheel stoppers 7, 7 are provided on both sides of the reinforcing plate 5a.

The cylinder 3 is placed horizontally on a beam 8 installed at the upper end between the pillars 1c and 1d, and a sprocket 9 and an arm 10a are rotatably provided at the tip of a piston rod 3a of the cylinder 3.
An engagement pin 10 is attached to the tip of the arm 10a. A rack body 11 having a notched locking groove 11a is provided on the beam 8, which is on the path along which the engaging pin 10 moves with the forward and backward movement of the piston rod 3a. The sprocket 9 has one end connected to the side of the cylinder 3,
A chain 12 is hung, the other end of which is connected to the end of each support beam 4, 4, and the piston rod 3
The support beams 4, 4 are raised and lowered by the forward and backward movement of a, and the drive-on plate 5 is moved up and down. And when the drive-on plate 5 reaches the top stage,
The engagement pin 10 falls into the cut-out locking groove 11a, and the fall prevention mechanism works. A push-up bar 14 is provided on the side of the cut-out locking groove 11a, as shown in FIG. When the lock release lever 13 is lifted up, the push-up bar 14 is lifted and cuts the engagement pin 10 into the lock groove 11.
a to release the fall prevention mechanism. Further, a push button switch 15 is attached to the support post 1d near the lower end position of the lock release lever 13, so that when the drive-on plate 5 is lowered, the lever operation and button operation can be performed in succession. It's summery.

Although not shown, the well-known elevating mechanism in a two-level multi-level parking system involves elevating and lowering a support beam suspended by a chain using cylinders erected parallel to the pillars, or by using a drive-on plate with both sides It is also possible to employ a well-known mechanism in which the drive-on plate is supported by a mold-parallel expansion and contraction mechanism and the end of the drive-on plate is pushed up by a piston rod.

If the drive-on plate is provided with a wheel stopper as in the above embodiment, the parking position will be regulated and the vehicle will not be allowed to enter too much, and if the entry side is made slightly higher, the weight of the vehicle will be reduced. It is safe because there is no risk of the vehicle slipping even if it bends.

When the two-stage multilevel parking system formed in this way is arranged horizontally in a single row, as shown in Figure 5, the columns 1a and 1b on one side with narrow spaces between the columns are placed between the columns 1c and 1d on the other side with wide spaces between the columns. Therefore, the dead space D between the adjacent vehicle entry spaces P has a width equivalent to one support column, and the installation space can be used effectively.

Incidentally, in the case of the parking device in this example, the width of the device is approximately
250cm, and the thickness of the pillars is approximately 25cm. Conventional equipment is placed next to each other, so 2500cm is required for 10 units, but if these are arranged so that the pillars overlap, one unit can be installed within an interval of 2500cm. It is possible to arrange as many as 11 units.

In the above-mentioned embodiment, a single device has space for one vehicle to enter on the upper and lower sides, but it is also possible to provide space for a plurality of vehicles to enter on the same drive-on plate.

Effects of the invention According to the invention, when arranged horizontally, the pillars on one side fit between the pillars on the other side, so the dead space between adjacent vehicle entry spaces is halved, which greatly contributes to the effective use of the site. There are merits.

Therefore, the contribution of expanding parking lots within the limited space in the city is enormous.
