[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pallet for a vehicle between a plurality of loading / unloading ground-side parking spaces arranged in parallel on the ground side and a plurality of underground parking spaces provided in a pit. Regarding the multi-storey underground parking device to be stored,
In particular, the present invention relates to measures for reducing a local weight load on a lifting chain for lifting a pallet.

[0002]

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 parallel parking spaces are arranged so that they can be raised and lowered with respect to the above-mentioned upper parking spaces in each place, 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 space and the underground parking space, and the vehicle is loaded and unloaded.

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.

According to the second aspect of the present invention, the supporting means is composed of two kinds of supporting members that can lift up and down the middle tier and the lowermost pallet of the underground parking space as a single unit.

Specifically, the solution means taken by the invention of claim 2 is, in addition to the constituent features of the invention of claim 1,

When the supporting means is composed of the first support tool and the second support tool, and the elevating chains facing each other are driven in one of the inner and outer directions, only the first support tool is used as the intermediate layer. While the pallet is moved up and down by engaging it with the four corners of the pallet, the second supporting tool is engaged with the four corners of the pallet in the lowermost layer when the lifting chains facing each other are driven around the other. It is configured to raise and lower the pallet.

With this configuration, in the invention according to claim 2, when the vehicle is loaded and unloaded from the pallet in the middle layer, the pallets in the upper and lower intermediate layers and the pallet in the ground parking space are adjacent to each other. After forming a space for raising and lowering the pallet by retreating horizontally in rows, each elevating chain is driven so that the elevating chains facing each other rotate inward and outward, and the first support is provided at the four corners of the pallet in the middle layer. Only the tools are engaged, and in this state, the pallet in the middle layer is individually raised to the parking space on the ground side to load and unload the vehicle. 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 raise and lower by itself, and the load applied to the support of each lifting chain is always only for a single pallet, and the output of the drive source for driving the lifting chain is small.

Further, in addition to the constituent features of the invention according to claim 1 or claim 2, the solution provided by the invention according to claim 3 is that the above-mentioned parking space row on the ground side and each underground parking space row on each intermediate layer And pallet traverse means for traversing the pallet. 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.

With this configuration, in the invention according to claim 3, at least the pallet traversing means of the intermediate layer does not have a driving source on the pallet side, and the pallet traversing means of the intermediate layer does not have a driving source on the fixed side of the underground parking space. 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.

46b is in a disengaged state with the first and second support members 4
2 and 43 are positioned immediately below the holes 46a and 46b and are on standby so as to be immediately engaged with the holes 46a and 46b by driving around the inside of the elevating chain 37.

First, when the vehicle X is stored in the ground side parking spaces 2a to 2d on the first floor 1F, the second second ground side parking space 2b from the left in FIG. 11 is an empty space. Therefore, the vacant first of the remaining first, third and fourth ground side parking spaces 2a, 2c, 2d
The vehicle X is moved forward into the pallet P1 and stored. On the other hand, the unloading of the vehicle X from the first, third, and fourth ground side parking spaces 2a, 2c, 2d leaves the vehicle X in the forward direction from the direction opposite to the warehousing direction. In addition, normally, the second pallet P2 or the third pallet P3 in the empty space row may be raised to the first floor 1F above the ground to close the empty space of the ground side parking spaces 2a to 2d.

Next, of the middle-tier parking spaces 8a to 8d on the first basement floor B1F, the vehicle X is placed on the second pallet P2 of the third third-tier parking space 8c from the left in FIG. The case of loading and unloading will be described.

The second of the parking space 8c on the side of the third intermediate layer
Since the first pallet P1 exists above the pallet P2 and the second second ground side parking space 2b from the left is an empty space, the first pallet P1 located in the third ground side parking space 2c. Is driven by the motor of the first traverse means 10 in the reverse rotation direction to drive the second ground side parking space 2
By laterally retreating to b (empty space), a space for raising and lowering is formed above the second pallet P2 of the third intermediate layer side parking space 8c.

Thereafter, the elevating motor 22 is rotated in the reverse direction, and the front and rear rotary shafts 26, 26 are rotated outwardly while being synchronized by the synchronizing means 29, so that the elevating chains 37, 37 facing each other forward and backward are rotated outward. Each elevating chain 37 is driven so as to make it. This makes each first
The protrusion 45a of the support tool 42 is individually provided in the hole 46a of each rail 14 of the second pallet P2, and the protrusion 45a of each second support tool 43 is individually provided in the hole 46b of each protrusion 47 of the third pallet P3. The second pallet P2 is lifted together with the third pallet P3 while engaging both pallets P2 and P3 in a horizontal state, and the second pallet P2 reaches the third ground side parking space 2c (empty space). Lifting motor 22
Reverse rotation is stopped to stop the drive of each lifting chain 37, the second pallet P2 is positioned in the third ground side parking space 2c, and then the above-mentioned first, third and fourth ground side parking spaces 2a, Similarly to the case of loading and unloading the vehicle X to and from the first pallets P1 of 2c and 2d, the vehicle X is forwardly loaded and unloaded to and from the second pallet P2. When the vehicle X is caused to move, the vehicle X is moved forward from the opposite direction to the time of entering the vehicle.

Then, the third above-ground parking space 2c
In order to return the second pallet P2 used for loading and unloading of the vehicle X to the intermediate space parking space in
To rotate the front and rear rotary shafts 26, 26 in synchronization with each other.
The support chains 42 and 43 are rotated inwardly while being synchronized with each other, and the support chains 42 and 43 are driven in such a manner that the support chains 42 and 43 facing each other inward and backward are rotated inward. , 46b, the rail 14 of the second pallet P2 is placed on the drive roller 17b and the driven roller 18b of the third intermediate layer side parking space 8c, and the third pallet P3 is placed on the upper surface of the seat portion 35a (mat 36). Both pallets P until they touch each other
The second pallet P2 is returned to the third intermediate layer side parking space 8c and the third pallet P3 is returned to the third lowermost layer side parking space 9c by lowering the second pallets P2 while keeping them horizontal. In this case, the lifting motor 22 is excessively rotated forward by a slight amount from the time when the pallets P2, P3 reach the third parking spaces 8c, 9c, and then stopped, so that the respective support tools 42, 43 are stopped. Pallets P2, P
The holes 46a and 46b of No. 3 are disengaged from each other and positioned immediately below the holes 46a and 46b.

Next, of the lowermost parking spaces 9a to 9d on the second basement floor B2F, the vehicle X is placed on the third pallet P3 of the third lowermost parking space 9c from the left in FIG. The case of loading and unloading will be described.

The third of the third lowest parking space 9c
Since the first pallet P1 and the second pallet P2 are present above the pallet P3, and the second second ground side parking space 2b and the second middle tier side parking space 8b from the left are empty spaces. As described above, the first pallet P1 in the third ground side parking space 2c is evacuated to the second ground side parking space 2b by the first traverse means 10 and the second pallet in the third middle tier side parking space 8c. P2 is driven in reverse by the lateral movement means 16 of the second traverse means 13, that is, in the reverse rotation of the motor 17, to reversely rotate the drive roller 17b and the driven roller 18b and the rail 14 and the second intermediate layer side parking space. By laterally retreating to 8b (empty space), an elevating space is formed above the third pallet P3 in the third lowermost parking space 9c.

Thereafter, as described above, the lifting motor 22 is rotated in the reverse direction to drive the lifting chains 37 so that the lifting chains 37, 37 facing each other forward and backward are rotated while the front and rear rotary shafts 26, 26 are synchronized. Then, the convex portions 45a of the respective second support members 43 are individually engaged with the hole portions 46b of the respective projecting pieces 47 of the third pallet P3, and the third pallet P3 is raised while keeping the horizontal state. When the third pallet P3 reaches the third ground side parking space 2c, the reverse rotation of the lifting motor 22 is stopped to stop the drive of each lifting chain 37, and the third pallet P3 is positioned in the third ground side parking space 2c. . Thereafter, as in the case of loading and unloading the vehicle X to and from the second pallet P2 as described above, the vehicle X is forwardly loaded and unloaded to the third pallet P3, while the vehicle X is loaded and unloaded to the third pallet P3. When leaving the vehicle, the vehicle X is moved forward from the opposite direction to the time of entering the vehicle.

Then, the third above-ground parking space 2c
In order to return the third pallet P3 used for loading and unloading of the vehicle X to the lowermost parking space, the elevating motor 22 is normally rotated as described above, and the elevating chains 37, 37 facing each other in the front and rear are inward. By driving each elevating chain 37 so as to rotate, the third pallet P3 is moved until the third pallet P3 abuts on the upper surface of the seat portion 35a with each second support tool 43 engaged with the hole portion 46b. The third pallet P3 is returned to the third lowest parking space 9c while being kept horizontal. Also in this case, the lifting motor 22 excessively forwardly rotates the third pallet P3 by a slight amount from the time when the third pallet P3 reaches the third lowermost parking space 9c, and then stops.
Disengage from the hole 46b of the pallet P3,
The hole 46b is positioned immediately below.

Therefore, in the first embodiment,
When moving up and down the second pallet P2 of the parking spaces 8a to 8d on the intermediate layer side, four lifting chains 37 are provided for the holes 46a on the left and right of the rail 14 on the front and rear of the second pallet P2.
While each of the first support tools 42 of the four lifting chains 37 individually engages with the holes 46b of the projecting pieces 47 at the four corners of the third pallet P3, the lowermost layer When the third pallet P3 in the side parking spaces 9a to 9d is moved up and down, the second support 4 of the four-row lifting chain 37 is inserted into the holes 46b of the projecting pieces 47 at the four corners of the third pallet P3.
3 will be engaged individually. Therefore, as in the case of lifting and lowering the pallet in the middle-layer parking space by a lifting chain that is connected only to the pallet in the lower-layer parking space, the connecting portion (supporting means) of the pallet in the lowermost layer.
The loads of both pallets are not concentrated on the pallets, and the load when the pallets are moved up and down can be efficiently distributed to the support members 42, 43 of the second and third pallets P2, P3 to be small. Moreover, each hole 46 of the second and third pallets
The first and second of each lifting chain 37 with respect to a and 46b
Since the supports 42 and 43 are individually engaged,
The lift post for the pallet in the lowermost layer, which was necessary for raising and lowering the pallet in the middle layer, is no longer required, and the third pallet P3 of the lowermost layer side parking spaces 9a to 9d in the ground side parking spaces 2a to 2d (empty space). On the other hand, when the vehicle X is loaded or unloaded, the push-up post protruding upward is not located on the entry / exit path of the vehicle X, and the third pallet P of the lowermost parking spaces 9a to 9d is provided.
It is possible to improve the loading / unloading property of the vehicle X with respect to the vehicle No. 3. Further, it is not necessary to secure the height of the parking spaces 2a to 2d sufficiently so that the lifting posts do not interfere with the upper wall of the ground side parking spaces 2a to 2d due to the elimination of the lifting posts, and the ground side parking spaces 2a to 2d. Is as compact as the case of the flat parking system, and it is possible to save space on the ground side parking spaces 2a to 2d.

Moreover, the second traversing means 1 on the first basement floor B1F
3, the rail 14 is provided on the second pallet P2 side, and the lateral movement means 16 (motor 17) serving as a drive source is provided on both lateral beams 5 in front of and behind the frame body 7. Therefore, the power source is the intermediate layer parking space 8a. It is sufficient to supply it to the lateral moving means 16 attached to both lateral beams 5 that are fixed sides in 8d to 8d, and it is not necessary to supply power to the second pallet P2 that traverses and ascends and descends in the middle-tier parking spaces 8a to 8d. The wiring system around the second pallet P2 can be made very simple, and failures such as disconnection of the wiring system can be reduced.

(Second Embodiment) FIGS. 13 to 16
Relates to the second embodiment of the present invention, in which the configuration of the supporting means is changed.

That is, in this embodiment, as shown in FIGS. 13 and 16, the supporting means 51 is the first supporting member 4 provided on the inner folded portion 37a of each lifting chain 37.
2 and a second support 52 provided on the outer folded portion 37b of each lifting chain 37.

The supporting means 51 is arranged so that the lifting chains 37, 37 facing each other in the front-rear direction rotate outward (rotate in the direction of the broken line arrow shown in FIG. 13).
When 7 is driven, only each first support tool 42 is engaged with the four corners of the second pallet P2 in the intermediate-layer side parking spaces 8a to 8d to move the second pallet P2 up and down.
This is the same as that of the above-described first embodiment, and each first support tool 42 is configured to engage with only the four corners of the second pallet P2. On the other hand, each of the second support tools 52 is not different from the configuration of each of the first support tools 42, but the lifting chains 37, 37 facing each other in the front-rear direction are rotated inward (see FIG. 1).
When the lifting chains 37 are driven so as to rotate in the direction indicated by the solid line arrow 3), only the second support members 52 are engaged with the four corners of the third pallet P3 in the lowermost parking spaces 9a to 9d. The third pallet P3 is moved up and down.

Each of the second supporting members 52 is shown in FIGS.
As shown in FIG. 5, the third pallet P3 on the second basement floor B2F is provided so as to project outward from the outer folded portion 37b of each lifting chain 37 so that the outer ends thereof correspond to the four corners of the third pallet P3. The recess 45b of each of the second support members 52
Has a tapered surface whose outer surface is inclined so as to widen the opening of the concave portion 45b as it goes upward, and the convex portion 45a is formed in a tapered shape from the base portion to the tip.

At the front and rear right and left ends of the third pallet P3, the outer side of the lifting chain 37 projects outward (opposite to the third pallet P3), and then the left and right inner sides face each other (the lifting chain 37 side). A substantially L-shaped projecting piece 54 is provided. Each of the projecting piece portions 54 has an outward projecting portion 54a extending obliquely downward so that the lower surface thereof has a seat portion 35a.
While being formed so as to contact the mat 36 of
The inwardly bent portion 54b is the second support member 52.
It corresponds to the outer edge of. The front end side of the bent portion 54b has a concave portion 45b of the second support 52.
Is formed on an engagement piece that enables engagement with the. The outer surface of the bent portion 54b (engagement piece) is also formed as a tapered surface in the same direction as the outer surface of the recess 45b of the second support tool 52 so that the second support tool 52 can be engaged with the recess 45b. I am trying to do it smoothly.

The elevating chains 37 for turning the elevating chains 37 facing each other forward and backward from each other are rotated outward.
When driving, the convex portion 45a of each first support tool 42 is engaged with the hole portion 46a of each rail 14 of the second pallet P2, and the second
Only the pallet P2 is raised while being kept horizontal. On the other hand, when driving the lifting chains 37 that turn the lifting chains 37, 37 facing each other inward and backward, the concave portions 45b of the second support members 52 into the bent portions 54b of the protruding pieces 54 of the third pallet P3. The third pallet P3 is raised while being held in a horizontal state by engaging with the joint piece).

In this case, the lowering of the third pallet P3 is performed by driving the respective elevating chains 37 that rotate the elevating chains 37, 37 facing each other forward and backward, but when the third pallet P3 rises, the amount of the upward movement is increased. Since the first support tool 42 has moved to the outer folded portion 37b via the driven sprocket 33 by the amount of rotation around the inside of each lifting chain 37, the lifting chains 37, 37 are moved to each other when the third pallet P3 is lowered. Even when driven outward, the convex portions 45a of each first support 42 and the second pallet P2
Does not engage with the hole 46a of each rail 14.
In addition, when the second pallet P2 is raised, the second rotation amount corresponding to the ascending movement of the second pallet P2 causes the second rotation amount of the outer rotation of the respective elevating chains 37
Since the support tool 52 moves to the inner folded portion 37a via the driven sprocket 33, even if the lifting chains 37, 37 are driven inward when the second pallet P2 is lowered, the recesses of the respective second support tools 52 are driven. 45b and third pallet P
3 does not engage with the bent portion 54b.

The structure of the first supporting member 42 is the same as that of the above-mentioned first supporting member.
The third embodiment is the same as that of the first embodiment, and the same parts as those of the first embodiment are denoted by the same reference numerals in other parts, and the detailed description thereof will be omitted.

Next, a procedure for loading and unloading the vehicle X will be described.

In this case, as a premise, the first support tool 42 of the lifting chain 37 and the hole 46a of the second pallet P2 in each lifting device 21 are not engaged with each other, and the first support tool 42 and the recess 45b of the second support tool 52 are in contact with each other. The bent portion 54b of each protruding portion 54 of the third pallet P3 is also in a non-engaged state. Also, the first
The support tool 42 is an inner folded portion 37 of the lifting chain 37.
On the a side, directly below the hole portion 46a, the second supporting member 52 is provided on the outer folded portion 37b side of the elevating chain 37 and each projecting piece portion 54 is formed.
Are respectively positioned directly below the bent portions 54b of the first lifting tool 37, the first support tool 42 is bent into the hole 46a when the lifting chain 37 is driven outside, and the second support tool 52 is bent when driving the lifting chain 37 inside. It is assumed that each of the portions 54b is waiting for immediate engagement.

First, of the case where the vehicle X is loaded / unloaded from / to the second pallet P2 of the third middle-tier parking space 8c shown in FIG. 11 among the middle-tier parking spaces 8a-8d on the first basement floor B1F. explain.

The second of the parking space 8c on the side of the third intermediate layer
The first pallet P1 above the pallet P2 is laterally retracted to the second ground side parking space 2b (empty space) by driving the motor of the first traverse means 10 in the reverse rotation direction, so that the third intermediate layer side A space for raising and lowering is formed above the second pallet P2 in the parking space 8c.

Thereafter, the elevating motor 22 is rotated in the reverse direction, and the front and rear rotary shafts 26, 26 are rotated outwardly while being synchronized by the synchronizing means 29 to drive the respective elevating chains 37 outwardly. At this time, the outer folded portion 37
The second support 52 of b is moved to the inner folded portion 37a side via the driven sprocket 33.

By driving the lifting chains 37 around the outside, the convex portions 45a of the first supporting members 42 are individually engaged with the holes 46a of the rails 14 of the second pallet P2, and only the second pallet P2 is engaged. While being kept horizontal, the vehicle X is moved forward to the second pallet P2 while the vehicle X is moved forward to the second pallet P2 and positioned.
When the vehicle X is to be unloaded from the pallet P2, the vehicle X is unloaded in the direction opposite to the direction in which the vehicle is loaded.

Then, the third above-ground parking space 2c
In order to return the second pallet P2 used for loading and unloading of the vehicle X to the intermediate space parking space in
By rotating each lifting chain 37 inward by rotating the first supporting member 42 only in the hole 46a.
, The rail 14 of the second pallet P2 is lowered until it abuts on the drive roller 17b and the driven roller 18b of the third intermediate layer side parking space 8c, and the second pallet P2 is moved to the third intermediate layer. It is returned to the side parking space 8c. In this case, the lift motor 22 is rotated forward slightly by a slight amount from the time when the second pallet P2 reaches the third intermediate layer side parking space 8c, and then stopped, thereby stopping each first support tool 42. Hole 46a of pallet P2
In the non-engaged state with respect to, while being positioned immediately below the hole 46a, each second support member 52 is moved to the outer folded portion 37b side via the driven sprocket 33,
The protrusions 54 are positioned immediately below the bent portions 54b.

Next, in the case where the vehicle X is loaded / unloaded into / from the third pallet P3 of the third lowest parking space 9c shown in FIG. 11 among the lowermost parking spaces 9a to 9d of the second basement floor B2F. Will be described.

The third of the third lowest parking space 9c
The first pallet P1 above the pallet P3 is laterally evacuated to the second ground side parking space 2b by the first traverse means 10 and the second pallet P2 located in the third middle tier side parking space 8c is evacuated.
The pallet P2 is laterally evacuated together with the rail 14 to the second intermediate layer side parking space 8b (empty space) by driving the pallet P2 along with the reverse rotation of the motor 17 of the lateral moving means 16 of the second traverse means 13, and the third lowermost layer. A space for lifting is formed above the third pallet P3 in the side parking space 9c.

Thereafter, the elevating motor 22 is normally rotated to drive the elevating chains 37 inward while synchronizing the front and rear rotary shafts 26, 26 with each other. At this time, the first support tool 42 of the inner folded portion 37a is moved to the outer folded portion 37b side via the driven sprocket 33.

By driving the inside of each of the elevating chains 37, the concave portions 45b of the second supporting members 52 are individually engaged with the bent portions 54b of the projecting pieces 54 of the third pallet P3, and the third pallet P3. Only the third pallet P3 reaches the third parking space 2c on the ground side, and the normal rotation of the lifting motor 22 is stopped to stop the driving of each lifting chain 37. After positioning the pallet P3 in the third parking space 2c on the ground side, the vehicle X is loaded forward to the third pallet P3, while the vehicle X is loaded to the third pallet P3 when the vehicle is loaded. Leaves the vehicle X forward from the opposite direction.

Then, the third above-ground parking space 2c
In the case of returning the third pallet P3 used for loading and unloading of the vehicle X to the lowermost parking space in
Is reversely rotated to drive each of the lifting chains 37 to the outside, so that only each second support tool 52 is bent.
4b, the third pallet P3 is seated on the seat 35.
The third pallet P3 is lowered while being kept in a horizontal state until it comes into contact with the upper surface of a, and the third pallet P3 is returned to the third lowermost parking space 9c. In this case, the second motor 52 is excessively reverse-rotated by a slight amount from the time when the third pallet P3 reaches the third lowermost parking space 9c, and then stopped, so that each second support tool 52 is moved to the third position.
The pallet P3 is disengaged from the bent portion 54b, positioned directly below the bent portion 54b, and each first support 42 is moved to the inner folded portion 37a side via the driven sprocket 33. Hole 46a
It is positioned just below.

Therefore, in the second embodiment,
When the second pallet P2 of the middle-tier parking spaces 8a to 8d is moved up and down, each elevating chain 37 is driven outward so that the front and rear rails 14 of the second pallet P2 can be moved only to the left and right holes 46a. Only the respective first supports 42 of the lifting chain 37 are individually engaged, while driving the lifting chains 37 inward when the third pallet P3 of the lowermost parking spaces 9a to 9d is lifted and lowered. Then, only the second supporting members 52 of the four-row lifting chain 37 are individually engaged only with the bent portions 54b at the four corners of the third pallet P3. As a result, the second pallets P2 of the intermediate-layer parking spaces 8a to 8d are driven by driving the respective lifting chains 37 around the inside or outside.
Alternatively, the third pallet P of the lowermost parking spaces 9a to 9d
3 can be engaged to raise and lower both the pallets P2 and P3 individually in both the second pallet P2 and the third pallet P3.
The load applied to each of the supports 42 and 52 of No. 7 is always a single second.
Only the pallet P2 or the third pallet P3 is provided, and the elevating motor 22 (driving source) for driving the elevating chain 37 can have a small output.

The present invention is not limited to the above-mentioned embodiments, but includes various other modifications. For example, in each of the above embodiments, the intermediate layer is underground 1
Underground multi-tiered parking device 1 with only two levels below ground level B1F
However, an underground multi-tiered parking device with three or more underground layers having a plurality of intermediate layers may be configured.

In each of the above embodiments, each floor 1F to.
In B2F, parking spaces 2a-2d, 8a-8d,
Although the underground multi-stage parking apparatus 1 in which four 9a to 9d are arranged side by side is configured, two or more underground multi-stage parking apparatuses except four parking spaces on each floor may be arranged in parallel. Further, in each of the above embodiments, the underground multi-tiered parking system 1 having no parking space above the first floor 1F is constructed, but a pallet that moves up and down or traverses to the space above the first floor is also multi-tiered. Then, the number of parking lots in the same site area may be increased.

As described above, according to the multistage underground parking apparatus of the invention of claim 1, four lifting chains are provided between the four corners above and below the four corners of the parking space row corresponding to each upper parking space. Since the pallets in the underground parking space are individually provided with support means for engaging and supporting the pallets, the load of both pallets when raising and lowering the pallets in the middle layer and the bottom layer is concentrated on the support means of a single pallet. It is possible to efficiently disperse and reduce the size to other pallet supporting means. Moreover, when a vehicle is loaded into or unloaded from the bottom pallet in the parking space on the ground side, obstacles such as push-up posts are removed from the entry / exit path of the vehicle to improve the entry / exitability of the vehicle to / from the bottom pallet. In addition, the parking space on the ground side can be made as compact as that of the flat parking system, and the space for the parking space on the ground side can be reduced.

According to the underground multi-stage multi-storey parking apparatus of the second aspect of the present invention, the first engagement that engages each lifting chain only with the pallet of the intermediate layer by driving the lifting chains facing each other in one direction. Since the tool and the second engaging tool that engages only the lowermost pallet by driving the lifting chains facing each other in the other direction, the pallet can be lifted and lowered individually. It is possible to make the load applied to the engaging tool of (1) always smaller than that of a single pallet, and to reduce the output of the drive source for driving the lifting chain.

Further, according to the multi-storey underground parking apparatus of the third aspect of the invention, at least the intermediate layer pallet traversing means is composed of the pallet side rail and the fixed side drive roller of the underground parking space. Therefore, the drive source to the pallet side is unnecessary, the wiring system around the pallet can be made very simple, and failures such as disconnection of the wiring system can be reduced.
