Description

[Detailed description of the invention] [Field of industrial application] The present invention provides a two-stage elevating parking device, particularly a pallet on which a car is mounted, and the pallet is driven along the main pillar of the parking device to move up and down. The present invention relates to a two-stage elevating parking device configured to be movable up and down in both directions.

[Background Art] With the spread of automobiles, securing garages for storing automobiles has become a problem. Particularly in cities and their suburbs, it is difficult to secure land for garages due to land shortages. Therefore, it is necessary to make effective use of garage land, and for example, as shown in Figure 3, a two-stage elevating parking system that can store two cars in one storage space is being considered. I'm getting old. Fig. 3 is a schematic side view of a two-stage elevating parking device, in which reference numeral 1 is a pallet on which a car is mounted and is configured to be able to rise and fall freely, 2 and 3 are main pillars, and 4 is a pallet on which a car is mounted. A chain 5-1 is provided near the lower end of the main column 3 to lock one end of the chain 4, and 5-2 is a lower end locking means provided near the upper end of the main column 2. upper end locking means 6 for locking the other end of the chain 4;
7 is a motor, 7 is a drive shaft which is provided with a sprocket wheel (not shown) and rotates by being driven by the motor 6 via the sprocket wheel; 8 is a pillow block supporting the drive shaft 7; 9- 1 to 9-3 are rotatable chain rollers that mesh with the chain 4, and 10 is a pallet 1.
This represents a landing detection device for detecting the landing of a person. Note that the chain rollers 9-1 and 9-
2 is mounted fixedly and rotatably on the pallet 1 and moves together with the pallet 1. Further, the chain roller 9-3 is fixedly and rotatably provided near the upper end of the main column 2. Although not shown, main pillars similar to the main pillars 2 and 3 are provided at positions facing the main pillars 2 and 3 with the pallet 1 in between, and the chains 4,
Lower end locking means 5-1, upper end locking means 5-2, pillow block 8, chain rollers 9-1 to 9-
The 3rd class is produced symmetrically. Hereinafter, the operation of the two-stage elevating parking device shown in FIG. 3 will be briefly explained with reference to FIG. 4. Note that the reference numeral 9 in FIG.
-4 represents a sprocket wheel fixed to the drive shaft 7 and meshed with the chain 4 to drive the chain 4, and other symbols correspond to those in FIG.

In FIG. 4, the center of gravity of the pallet 1 is at least on the right side of the chain roller 9-2 (in the direction of vehicle loading), as indicated by the arrow W in the figure.
(This state is the same even when a car is mounted on pallet 1). Therefore, a force is acting on the pallet 1, centering on the chain roller 9-2, which tends to cause the right side to move downward and the left side to rise upward. However, the palette 1
is supported by the chain 4 between the upper end locking means 5-2 and the chain roller 9-3 in the chain roller 9-2, and the lower end locking means 5-
It is supported in the opposite direction by the chain 4 between the sprocket wheel 9-4 and the sprocket wheel 9-4 to keep it horizontal.

The pallet 1 is moved up and down by a motor 6. That is, the sprocket foil 9-4
is fixed to a drive shaft 7, and rotates when the drive shaft 7 is driven by the motor 6. And the above sprocket foil 9-4
When the rotating direction is clockwise, the chain 4 is driven in the direction of arrow a in the figure, and the pallet 1 is raised. Further, when the direction of rotation of the sprocket wheel 9-4 is counterclockwise, the chain 4 is driven in the direction of arrow b in the figure, and the pallet 1 is lowered. In this case, the length of the chain 4 (between the lower end locking means 5-1 and the upper end locking means 5-2) is constant, and for example, when the pallet 1 is raised, the length of the chain 4 is constant. Because the shorter length of the chain 4 between the chain roller 9-3 and the longer length of the chain 4 between the lower end locking means 5-1 and the sprocket wheel 9-4 are equal. (The reverse is true when the pallet 1 is lowered.) The pallet 1 moves up and down while maintaining its horizontal state. Since the motor 6 is a so-called brake motor, the pallet 1 can be stopped at any desired position. However, in the event of a failure of the brake device of the motor 6 or a breakage of the chain 4, for example, the pallet 1 will descend, which is dangerous. Therefore, for such a case, for example, by installing a plurality of protruding members inside the main pillar 2 and protruding claw members provided at the edge of the pallet 1, it is possible to prevent the pallet 1 from descending. Known safety measures are in place to prevent this.

[Problem that the invention attempts to solve]

As shown in FIG. 4, for example, the pallet 1 in a conventional two-stage elevating parking system has a flat floor surface on which a car is mounted, and there is usually a pallet near the leading edge in the direction in which the car approaches. It is equipped with a car stop (not shown). Then, the car is driven over pallet 1 and stopped at the position where the wheels on the approach side touch the bollard, but since the bollard becomes a blind spot for the driving car and cannot be seen, the stopping position cannot be detected in advance. , there was a risk that the wheels would hit the car stop hard. As described above, if the wheels hit the bollard strongly when the vehicle is stopped, there is an undesirable problem in that the bollard may be damaged or the wheel may run onto the bollard.

[Means for solving problems]

The purpose of the present invention is to solve the above-mentioned problems, and therefore, the two-stage elevating parking device of the present invention is provided with a pallet on which a car is mounted, and the pallet is arranged along the main pillar of the parking device. In a two-stage elevating parking device that is driven and configured to move up and down in the vertical direction, the pallet is provided with a car stop near the leading edge of the floor surface on which the vehicle is mounted in the direction in which the vehicle approaches; It is divided into a plurality of sections in a direction perpendicular to the direction of advance and retreat, and at least the floor surface on which the first wheel in the approach direction is mounted when a vehicle is mounted has a step between it and the other floor surfaces. The step is configured to be lower than the other floor surfaces by a predetermined height, and the position of the step is located between the lower end of the wheel and the wheel stop when the first wheel contacts the wheel stop. It is characterized by being larger than the distance between them. This will be explained below with reference to the drawings.

〔Example〕

FIG. 1 is a perspective view of essential parts showing an embodiment of the present invention;
FIG. 2a shows a plan view of the main part of the pallet in FIG. 1, and FIG. 2b shows a view taken along arrow A in FIG. 2a.

Among the symbols in FIGS. 1 and 2 a and b, the same symbols as those in FIGS. 3 and 4 represent the same elements, 2-1 is the side frame of the main column 2, 3-1 is the main This is a connecting beam that connects columns 3 and 3. Next, the structure of palette 1 will be explained.

Reference numerals 11 and 11 designate a pair of side frames, which extend parallel to the forward and backward direction of the automobile (not shown), and have a wheel stopper 12 integrally provided inside the rear end portion (the left side portion in FIG. 2a). side frame 1
A plurality of horizontal bars 13 and 13' made of, for example, rectangular steel are disposed between the side frames 11 and 11, and the side frames 11 and 11 are fixed to each other. Next, vertical bars 14 and 14' are provided between adjacent horizontal bars 13 and 13 and between 13' and 13' at intervals corresponding to the distance between the left and right wheels of the automobile. Note that the vertical bar 14 at the tip of the pallet 1 (the right side in Fig. 2a)
The distance between a and 14a is formed to be slightly smaller than the distance between the vertical bars 14 and 14. Reference numerals 15 and 15' denote reinforcing horizontal beams, which are attached to the side frame 1 near where the wheels of the automobile are placed when the automobile is parked.
1 and the vertical bar 14a or 14'. The horizontal bars 13, 15 and the vertical bars 14, 14a
There is a height difference between the horizontal bars 13', 15' and the vertical bars 14'.
5' and the vertical bar 14' are at a predetermined height (for example, 40 mm) higher than the horizontal bars 13, 15 and the vertical bars 14, 14a.
mm) at a lower position. Next, reference numeral 16 denotes a plurality of plate ribs, which are formed of, for example, a steel plate so as to be lower toward the tip, and are provided in parallel to the side frame 11 on the horizontal bar 13 forming the tip.

17 to 20 are floorboards. And floorboard 1
7 is fixed to the upper surfaces of the horizontal bars 13', 15' and the vertical bars 14', floor surfaces 18 and 19 are fixed to the upper surfaces of the horizontal bars 13 and the vertical bars 14, and the floor surface 20 is fixed to the upper surfaces of the horizontal bars 13, 15'. , are fixed to the upper surfaces of the vertical beams 14a and the plate ribs 16. In this manner, when the floor plates 17 to 20 are fixed, a level difference is created between the floor plate 17 and the floor surface 18. Note that reference numeral 21 indicates a reinforcing plate, which is appropriately provided at a location where the side frame 11 and the horizontal beam 13 intersect or butt each other. Also, 22,2
Reference numerals 3 designate shafts on which the chain rollers 9-1 and 9-2 shown in FIG. 4 are rotatably mounted. By interposing the pallet 1 constructed as described above between the main pillars 2 and 2 and between the main pillars 3 and 3, a two-stage elevating parking device is formed.

When storing a car using the above configuration,
As shown in Fig. 1, if the pallet 1 is lowered and stopped on the floor, a wide slope is formed at the tip of the pallet 1, so that it can be moved forward or backward while cutting a curve, for example. , the wheels can be easily and smoothly guided onto the pallet 1. The car travels on the pallet 1 and stops at the position where the wheels on the approach side contact the bollard 12, but since the stopping position can be detected in advance due to the difference in level between the floor plate 17 and the floor plate 18, it is possible to detect the stopping position in advance by moving the wheels at the time of stopping. Strong contact with the car stop 12 can be avoided. That is, in the case shown in the figure, the width of the floorboard 17 is made larger than the distance between the lower end of the leading wheel and the wheel stopper when it comes into contact with the wheel stopper 12, and the driver can determine the parking position in advance. It has become detectable. In addition, pallet 1 equipped with a car
Even if the pallet 1 is tilted so that the floor plate 17 side is higher and the floor plate 20 side is lower during the ascent, the step has the effect of blocking the vehicle and can prevent the vehicle from moving in the opposite direction. .

In this embodiment, an example is shown in which the vertical bars and horizontal bars are made of a steel material consisting of a rectangular tube, but the invention is not limited to this, and solid steel material, hollow cylindrical steel material, or shaped steel may also be used. . Further, the number of vertical bars to be installed should be selected appropriately, taking into consideration the size, weight, etc. of the vehicle to be mounted. Furthermore, by appropriately selecting the spacing between the side frames and the spacing between horizontal bars, it is possible to use commercially available iron plates or steel plates with standard dimensions of 3' x 6' or 4' x 8' without much processing. I can do it. Further, although illustrations and descriptions are omitted in this embodiment, wheel stops for the backward direction, a fall prevention device, and other auxiliary devices can be attached to the pallet as necessary.

[Effect of idea]

Since the present invention has the structure and operation described above, the following effects can be expected.

(1) At least a step is created between the floor surface where the first wheel in the direction of vehicle approach is mounted and the other floor surfaces, so the stopping position can be detected in advance by the step, so the wheel strongly hits the car stop when stopping. In addition to this, the step also has the effect of blocking the vehicle in the opposite direction.

(2) Since the pallet is an integral structure, the structure is simple, and the strength and reliability are extremely high.

(3) Since the part where the car wheels are placed is reinforced, it will not deform even if a relatively thin floor plate is used.

(4) By appropriately selecting the spacing between the constituent members, commercially available fixed-length steel plates can be used, and not only processing and assembly work but also production management is extremely easy, and costs can be reduced.
