2. Description of the Related Art Conventionally, in such an underground multi-stage multi-storey parking system, as disclosed in Japanese Patent Publication No. 7-51853, for example, there are a plurality of above-ground parking spaces for loading and unloading on the ground side. Pits are provided in parallel below these ground-side parking spaces, and pits whose projected areas are almost equal to those of the above-ground parking spaces are provided. In the pits, the same number of underground-side parking spaces corresponding to the above-mentioned respective upper-side parking spaces are provided. Are provided in a plurality of layers in the vertical direction. Furthermore, in the above-ground parking space row, a number of pallets, which is one less than the number of parking spaces arranged in parallel, is arranged transversely to the adjacent above-ground parking space, and the underground parking space at the bottom of the pit is located. The same number of pallets as the number of parking spaces arranged side by side is arranged in the row so that it can be raised and lowered with respect to the above upper parking spaces in each location, and the number of parking spaces arranged in parallel in the underground parking space of the middle layer excluding the bottom layer of the above pit One less number of pallets is arranged so that it can traverse to the adjacent underground parking space and can move up and down with respect to each of the above upper parking spaces. And, in the pallet of the lowermost underground parking space, a push-up post that abuts on the bottom surface of the pallet in the underground parking space of the middle layer of the row to elevate and lower the pallet of the middle layer is erected. The pallet of the middle layer is moved up and down as the pallet of the lowermost layer is lifted by a lifting drive unit such as a lifting chain connected only to the pallet of the lowermost layer.

That is, when a vehicle is loaded and unloaded from the bottom pallet, the intermediate pallets in the same row and the pallets on the ground above the pallet are evacuated to the adjacent rows to provide a space for raising and lowering. After the formation, the bottom pallet is raised to the parking space on the ground side to load and unload the vehicle. On the other hand, when moving a vehicle in and out of a pallet in the middle tier, the middle tiers in the same row above and below the pallet in the middle tier and the pallets on the ground side are evacuated to the adjacent rows, and the pallets are raised and lowered. After forming the space in the same way,
With the lowermost pallet raised and the push-up post abutting the bottom of the middle pallet, the middle pallet is raised to the parking space on the ground side as the bottom pallet rises, and the vehicle is Carry out.

[0004]

However, in the above-mentioned conventional multilevel underground parking apparatus, since the lifting chain is connected only to the pallet in the lowermost layer, the pallet in the lowermost layer is lifted when the pallet in the middle layer is raised or lowered. The load of the pallet of the lowermost layer and the load of the pallet of the intermediate layer act on the connecting portion with the elevating chain, and a large load due to the load of both pallets acts locally. In particular, when the vehicle is mounted on the pallet in the bottom layer, the load acting on the connecting portion may become excessive and may cause inconvenience to the lifting function. Is necessary for parking equipment.

Further, since the lowermost pallet is provided with a push-up post, the push-up post is parked on the ground side when the vehicle is loaded or unloaded to / from the lowermost pallet raised to the ground side parking space. When the vehicle is loaded and unloaded from the pallet at the bottom of the space, the push-up posts are located on the loading and unloading path of the vehicle, which obstructs the loading and unloading of the vehicle. To do. Moreover, when the vehicle is loaded or unloaded from the pallet at the lowest level, the push-up posts project upward into the ground-side parking space, so the push-up posts do not interfere with the top wall of the ground-side parking space. There is also a drawback that the height of the parking space must be sufficiently secured and the parking space on the ground side becomes wider than that in the case of the flat parking system.

The present invention has been made in view of the above points, and an object thereof is to allow the pallets of the upper and lower underground parking spaces to be individually connected to the elevating chains so that the pallets are connected to the connecting portions. The purpose is to reduce the load by distributing it, and to eliminate the push-up posts to save and store the vehicle and save the parking space on the ground side.

[0007]

In order to achieve the above object, in the present invention, four endless lifting chains for lifting and lowering pallets in synchronization with the four corners of the underground parking space in each row are provided, and The pallets of each layer are individually engaged with the lifting chain.

Specifically, in the means for solving the problems according to the first aspect of the invention, a plurality of ground-side parking spaces for loading and unloading are arranged side by side on the ground side, and below the ground-side parking spaces. , A pit having a projection area substantially equal to that of the above-ground parking space is provided, and the same number of underground parking spaces corresponding to the above-mentioned upper parking spaces are provided in a plurality of layers in the vertical direction. The number of pallets, which is one less than the number of parallel parking spaces, is arranged in the above-ground parking space row so that it can traverse to the adjacent above-ground parking space. The same number of pallets as the number of parking spaces arranged in parallel are arranged so that they can be raised and lowered with respect to the above upper parking spaces in different places, and the parking spaces are arranged in the underground parking space row of the middle layer excluding the bottom layer of the pit. The number of pallets that is one less than the number of parallel installed parking spaces is such that it can traverse to the adjacent underground parking space and can move up and down to the above-mentioned upper parking spaces. And
Further, four endless elevating chains are arranged one by one at the four corners of the parking space row consisting of the underground parking spaces of upper and lower layers corresponding to the upper parking spaces of each place so that they can be synchronously driven in the vertical direction. Then, each of the lifting chains is provided with a supporting means for engaging and supporting the four corners of the pallet in each underground parking space so as to be individually engageable and disengageable, in correspondence with each underground parking space, and the synchronization of each lifting chain is performed. By driving, each supporting means is engaged with the pallet to move the pallet between the above-ground parking space and the underground parking space, and the vehicle is loaded and unloaded . In addition, four

Lifting chains facing each other drive in the other direction
At this time, use only the above-mentioned second support tool for the pallet in the bottom layer.
The pallet is moved up and down by engaging with the corner .

With this configuration, according to the first aspect of the invention, when a vehicle is loaded into or unloaded from a pallet in the middle layer, the pallets in the same layer above and below the pallet in the same row are underground parked in the adjacent row. The pallets in the parking lot on the ground side are evacuated to the parking spaces on the adjacent rows to form spaces for raising and lowering the pallets, and then each lifting chain is driven to move the four corners of the pallet in the middle layer. And the supporting means are individually engaged with the four corners of the pallet of the lowermost layer, and in this state, the pallet of the intermediate layer and the pallet of the lowermost layer are lifted together until the pallet of the intermediate layer reaches the parking space on the ground side, and the pallet of the intermediate layer is lifted. Carrying in and out of vehicles. On the other hand, when moving a vehicle in and out of the bottom pallet, the middle tier pallet in the same row above the bottom pallet and the pallet on the ground side are evacuated to the parking space in the adjacent row to lift the pallet. After the space is formed, each lifting chain is driven to individually engage the support means at the four corners of the pallet in the lowermost layer, and in this state, only the pallet in the lowermost layer is raised to the parking space on the ground side. Carry in and out. As a result, the pallets of each layer of the underground parking space are engaged (connected) with the four lifting chains by individual supporting means, and the lifting chains connected only to the lowermost pallet enable the intermediate layers Like lifting and lowering pallets, the load of both pallets does not concentrate on the connecting portion (engaging means) of the lowermost pallet when lifting and lowering the intermediate and lowermost pallets. The load of both pallets when raising and lowering the pallets is efficiently distributed to the supporting means of other pallets and becomes small. Moreover, since the supporting means of the four lifting chains are individually engaged with the pallet of each layer, the push-up post of the pallet of the lowermost layer, which is necessary for raising and lowering the pallet of the intermediate layer, becomes unnecessary, When the vehicle is loaded into or unloaded from the bottom pallet in the parking space on the ground side, the push-up post that protrudes upward is no longer located on the entry / exit path of the vehicle, and the entry of the vehicle into the pallet at the bottom Good delivery. Furthermore, by eliminating the push-up posts, it is no longer necessary to secure a sufficient height for the parking spaces so that the push-up posts do not interfere with the upper wall of the parking space on the ground side. Comparably compact.

Further, in the first aspect of the present invention, if for entry and leaving the vehicle with respect to the pallet of the intermediate layer, a pallet in the pallet and the ground-side parking space in the middle layer of the upper and lower, respectively adjacent rows After forming a space for raising and lowering the pallet by traversing and retreating, each elevating chain is driven so that the elevating chains facing each other rotate inward and outward, and only the first support tool is provided at the four corners of the intermediate pallet. In this state, the pallet of the middle layer is raised to the ground side parking space by itself, and the vehicle is loaded and unloaded. On the other hand, when loading and unloading vehicles from the lowest pallet, the intermediate pallets in the same row above it and the pallets in the above-ground parking space are transversely evacuated to adjacent rows to create a space for raising and lowering the pallets. After forming in the same manner, the lifting chains that face each other are turned to the other direction. By driving each lifting chain, the second support members are engaged only at the four corners of the lowermost pallet, and in this state, the lowermost pallet is singly used. Raise the car to the parking space on the ground side and place the vehicle in and out of the pallet at the bottom. Thereby, the pallet of the intermediate layer or the pallet of the lowermost layer is engaged by driving the elevator chains facing each other one or the other, and the pallet of the intermediate pallet or the pallet of the lowermost layer is engaged. It is possible to lift and lower by itself, and the load on the support of each lifting chain is always only for a single pallet,
The output of the drive source for driving the lifting chain is also small.

Furthermore, solutions of the invention is taken as claimed in claim 2, wherein, in addition to the configuration requirements of the invention of claim 1 Symbol placement, each underground side parking space train ground-side parking space train and the intermediate layer, the pallet A pallet traversing means for traversing is provided respectively. Then, among the pallet traversing means, at least the pallet traversing means of the intermediate layer is provided with a rail provided on the pallet side and a fixed side of each underground parking space row, and supports the pallet via the rail. A plurality of support rollers and a drive means provided on the fixed side of each underground parking space row and configured to roll each of the support rollers are provided, and the support rollers are adjacent to each other by rolling by the drive means. The pallet is made to traverse to the underground parking space.

[0012] With this arrangement, in the second aspect of the present invention, the pallet transverse section of at least the intermediate layer has no driving source to the pallet side, to the drive means of the fixed side of the underground side parking spaces of the intermediate layer Power should be supplied to the
In the middle layer, it is not necessary to supply power to the pallet that traverses and moves up and down, and the wiring system around the pallet becomes very simple, and failures such as disconnection of the wiring system are reduced.
