DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
The multi-layer circulating parking apparatus according to the third conventional example is configured such that a pair of chains, two pairs of guide rails, and a pair of levers are provided on both sides of the circulating apparatus in the circulation direction. In other words, the structure of the multi-layer circulating parking device itself is complicated, which is disadvantageous in terms of equipment cost, and the width of the multi-layer circulating parking device is inevitably widened, which is disadvantageous in terms of installation space. There is a problem to be solved.

In addition, the multi-layer circulating parking system according to the second conventional example has a structure that requires a pair of chains and two pairs of guide rails, and therefore the installation space thereof is larger than that of the above-described two conventional examples. It is considered to be advantageous, but the supporting roller of the pallet for storing a vehicle is configured to be simply guided by the semi-arcuate guide rail, and one of the guide rails is arranged so as to cross the arm. Nevertheless, there is a risk of instability when the car storage pallet is lowered from the upper side to the lower side and raised from the lower side to the upper side.

Therefore, in view of the above-mentioned circumstances, the present invention has a simple structure and can surely circulate the automobile storage pallet by moving it upward and downward and downward and upward. An object of the present invention is to provide a multi-layer circulation parking device that can be installed in a narrow installation space.

[0013]

Therefore, the feature of the main means adopted by the multi-layer circulating parking system according to the present invention is that the single wheels are arranged side by side and arranged on one side in one of the forward and backward directions in the width direction. And a pair of wheels in which upper and lower wheels are paired on the side of the single wheel in the other width direction and a locking member on the support side of the pair of wheels, and a single wheel on the opposite side of the pair of wheels.

[0014]

According to the multi-layer circulating parking apparatus having the above-mentioned structure according to the present invention, the pallet for storing the automobile has the single wheel provided on one side in one width direction of the pallet for storing the automobile and the forward / backward direction. On the other side of the single wheel, upper and lower wheels are supported at three points by a paired wheel and a single wheel provided on the opposite side of the paired wheel. Since the upper rail and the lower rail are sandwiched by the upper and lower wheels, the pallet for storing the vehicle does not tilt even if an unbalanced load is applied to the pallet for storing the vehicle depending on the mounting position of the vehicle. As the chain circulates, it moves horizontally through the chain attachment.

Further, when the pallet for storing a vehicle is at the end of these rails, the engaging member provided at the tip of the lever engages with the locking member, so that the pallet for storing the vehicle is engaged with the pallet for storing the vehicle. It is supported in a horizontal state regardless of an unbalanced load by a coupling member and two chain attachments that are connected to a wheel axle that supports a single wheel. It is lifted up and down horizontally at both ends of the circulation type parking device.

On the other hand, as described above, this multi-layer circulating parking system is composed of upper and lower rails, an endless chain, and a lever provided on the locking member side of a pallet for storing automobiles. As described above, since the pair of chains, the pair of guide rails, or the pair of endless chains, the pair of guide rails, and the pair of levers on both sides of the circulation device in the circulation direction are not provided, the configuration is simple. The width can be narrowed as well.

Since the pair of guide rails and the pair of levers are not provided on both sides in the circulation direction of the circulation device, the structure of the multi-layer circulation parking device 1 itself is larger than that of the multi-layer circulation parking device according to the conventional example. The structure is simple, the pallet 2 can be reliably moved up and down, the width of the multi-layer circulation parking device 1 can be narrowed, and the limited installation space can be effectively utilized.

Next, a multi-layer circulating parking system according to another embodiment of the present invention will be described with reference to FIG. 5 which is an explanatory view of the structure of the main parts thereof, and those having the same functions and functions as those of the above embodiments. Explaining only the differences in the configuration with the same reference numerals, the multi-layer circulating parking system is
As is well understood from the figure, the configuration of the engaging portion 3a of the locking member 3 provided on the pallet 2 and the engaging portion 12a of the engaging member 12 provided at the tip of the lever 11 are configured. And are only different.

That is, in this multi-layer circulating parking system, the locking member 3 provided on the pallet 2 is provided with the substantially rectangular notch-shaped engaging portion 3a, while the tip of the lever 11 is like a wheel of a rail traveling vehicle. , An engaging member 12 having a flange-shaped outer edge portion 12b
And the outer edge portion 12 of the engaging member 12 is supported by the engaging portion 3a.
The engaging portion 12a having a smaller diameter than b is configured to be fitted.

Therefore, when the pallet 2 is lowered from the upper side to the lower side and is raised from the lower side to the upper side, the engaging member 12 provided on the lever 11 is engaged as in the above embodiment. By engaging the locking portion 3a of the locking member 3 provided on the pallet 2 with the portion 12a, the pallet 2 is fixed by the lever 11, while the pair of wheels on the other side is fixed, as in the above embodiment. The side is fixed by a chain attachment, and the endless chain circulates and the lever 11
Due to the interlocking operation with the rotation of the pallet, the pallet 2 is moved up and down in a horizontal state and moved horizontally even though the pallet 2 is supported at three points. Therefore, the effect of this embodiment is the same as that of the above embodiment. .

In the above description, the multi-layer circulating parking apparatus having a structure in which a vehicle is placed on the pallet 2 in the horizontal movement direction has been described as an example. However, the technical idea according to the present invention is, for example, conventional. Similar to the multilayer circulating parking apparatus according to the example, the invention can also be applied to a vehicle having a pallet for mounting a vehicle in a direction orthogonal to the horizontal movement direction. The above embodiments are merely specific examples of the present invention, and therefore, the scope of the technical idea of the present invention is not limited by the above embodiments.

[0035]
