Description

  The present invention relates to a multistage elevating parking apparatus that includes a plurality of vehicle-mounted pallets in the vertical direction, and that lifts and lowers these vehicle-mounted pallets to enter and exit the vehicle at a loading section.

  Conventionally, as an example of a multistage elevating type parking apparatus, for example, the inclination of the elevating pallet is changed between the middle boarding position and the upper stage storage position, to facilitate the boarding of the vehicle at the boarding position, There is a parking device that prevents rainwater from dripping from the front end of the lifting pallet that is placed in the upper storage position (see, for example, Patent Document 1).

  As shown in FIG. 7, in this parking device 100, when the lifting pallet 101 is raised to the upper storage position, the tilting roller 102 presses the balance chain 103 relatively downward, thereby moving the lifting pallet 101 to “ In this way, rainwater does not fall from the front end.

  On the other hand, as another example of the multistage elevating parking apparatus, as shown in FIG. 8, a lower pallet 112 is arranged in an underground pit 111 provided with a frame assembly 110, and an upper pallet 113 is arranged on the upper part of the ground. An intermediate traverse pallet 115 that is one less than the number of columns is arranged in the intermediate space facing the section 114, and the upper and lower pallets 113 on the ground and the lower pallet 112 in the pit 111 are moved up and down in each chain. 116, the pit multi-stage ascending / descending traverse is performed by moving the upper and lower pallets 115 and 112, selectively moving the upper / lower pallets 113 and 112, and placing them in the middle loading / unloading section 114 after retreating the middle traversing pallet 115. There is a type parking device 117 (see, for example, Patent Document 2).

  In the pit multi-stage up-and-down traverse type parking apparatus 117, conventionally, the upper pallet 113, the middle pallet 115, and the lower pallet 112 are always lowered (while waiting, going up and down and traversing) to be inclined in a state of “backflow water gradient”. And the accumulated water W on the pallets 113, 115, 112 is caused to flow backward. In the case of such a configuration, as a means for holding the upper pallet 113 in the upper storage space, for example, as shown in FIG. 9, a fixing bracket 118 provided at the rear end of the pallet is provided on the frame assembly 110 (fixed side). A means for supporting by the claw member 120 of the locking device 119 is employed. When the upper pallet 113 is disposed in the middle loading portion 114, the claw member 120 of the locking device 119 is stored and the upper pallet 113 is lowered by the elevating drive device 116, and the fixing bracket 118 and the pallet front portion are moved. Are placed on the transverse rails 121 and 122 in the middle stage and arranged in a “backflow water gradient” state. In this way, the accumulated water W of the pallets 112, 113, 115 (particularly the upper pallet 113 stored in the upper position) that is waiting or ascending / descending is allowed to flow backward, and the user M who is waiting in front of the loading section has the falling water. To keep it from falling.

  However, in Patent Document 1, when the lifting pallet 101 is lowered, the lifting pallet 101 is changed to a “front downward slope” inclined state as the tilting roller 102 is detached from the balance chain 103 (see FIG. 7). As indicated by the dotted line), the accumulated water W of the lifting / lowering pallet 101 flows down from the tip and falls on the user M waiting at the loading section.

  In addition, as in Patent Document 2, all the upper, middle, and lower pallets 113, 115, and 112 that are employed in the pit multi-stage up-and-down traverse parking device are always inclined with a “backflow water gradient”. Since the pallets 113, 115, and 112 are moved up and down in the state of “backflow water gradient”, the user of the entry section does not get dropped water, but the upper and middle pallets 113 and 115 are placed in the entry section 114. By setting the height position of the rear traversing rail 121 to be arranged lower than the height position of the front traversing rail 122, the rear traversing rail 122 is made to be a “rear-flowing water gradient”. If the part is disposed so as to be disposed on the entry floor 123, the lower position in the pit 111 where the upper surface of the rear traverse rail 121 sinks below the surface of the entry floor 123. The be disposed.

  Then, the middle pallet 115 traverses on the front and rear traversing rails in a state of “rear-flowing water gradient”, and the upper pallet 113 descends while remaining in the state of “rear-flowing water gradient”. The pallet rear portion rests on the front traversing rail 122 and aligns with the loading floor 123, and the rear part of the pallet rests on the rear traversing rail 121 and is landed in a “rear-flow water gradient” state.

  Therefore, when the upper, middle, and lower pallets 113, 115, and 112 are always inclined at the “backward flow water gradient”, the lower pallet 112 is stored in the pit 111, and the middle loading portion 114 is placed. If the middle pallet 115 or the upper pallet 113 is disposed in the lower pallet 112, the vertical distance between the middle pallet 115 and the upper pallet 113 and the lower pallet 112 is narrowed at the rear, and the vehicle V having a predetermined vehicle height is accommodated in the lower pallet 112. For this purpose, it is necessary to increase the pit depth (L1) accordingly, resulting in an increase in the overall equipment cost due to an increase in the pit excavation cost.

  Accordingly, the present invention has an object to provide a multistage elevating parking apparatus that suppresses facility costs required for pits and the like and prevents falling water from falling on the pallet from being placed on the user when the pallet is placed in the entry portion. And

In order to achieve the above-mentioned object, the present invention has an entry part and a storage space for storing a vehicle-mounted pallet in the vertical direction, and lifts and lowers the vehicle-mounted pallet between the storage space and the entry part. In the multistage elevating parking apparatus provided with the means, when the vehicle-mounted pallet of the storage space located above is placed in the vehicle-mounted pallet, the vehicle-mounted pallet is arranged so that the rear part of the vehicle-mounted pallet is more than the vehicle floor. A rear-side mounting portion that is held at a high position, and the elevating means sets the vehicle-mounted pallet stored in a storage space located above the loading portion to be in a rear-lowering state during standby and elevating, From the state in which the upper pallet arranged in the loading portion is hung and lowered in a state of being lowered rearward until the rear portion is held on the rear placement portion, and the rear portion is held on the rear placement portion. The front of Rett is swung downward and a swing lever body hung to the state of the forwardly downwardly arranged on the driving into the floor.

As a result, the upper pallet placed in the loading section is in a rear-lowering state in the standby state and the raised / lowered state in the upper storage space. After being placed on the side placing portion, the front portion of the pallet is lowered and placed on the boarding floor surface so as to be in a front-lowering state, so that the accumulated water does not fall on the user of the loading portion. In addition, by setting the pallet at the entry portion in a forward-lowering state, it is possible to reduce the equipment cost required for the pits and the like. In addition, the swing lever body can swing the pallet descending in the rear-lowering state from the state holding the rear part to the front-lowering state with a simple configuration.

  Further, the storage space is composed of a plurality of rows and multiple stages including the storage space in the pit, the predetermined stage of the storage space is used as a loading section, and the pallet in the loading section is reduced by one unit from the number of columns and the loading is performed. The pallet of the section is configured to traverse, and the pallet of the other stage is configured to move up and down in the same row, and the rear traverse rail height position of the traversing pallet is set higher than the front traverse rail height position. And the upper surface of the rear traversing rail is disposed at a position above the floor surface, and the pallet traversing along the traversing rail is in a front-lowering state, and the pallet stored in the pit is on standby, The upper pallet placed in the loading section is set in the lowering state during standby and lifting, and the upper pallet is set in the lowering state when standing and raising and lowering. After the rear part of the pallet is held on the rear traverse rail, the pallet front part is swung downward and the pallet front part is placed on the loading floor so that the swing lever body is in a front-lowering state. It may be configured.

  In this way, in the pit multi-stage up-and-down traverse type parking device, the lower pallet stored in the pit is always in the front-lowering state, the traversing pallet in the loading section is in the front-lowering state, and the lower pallet in the rear part of the pallet Space is secured between the upper pallet and the lower pallet when the upper pallet is placed on the upper pallet. Space can be ensured reliably.

  The swing lever body is provided at the rear part of the side rising part of the upper pallet, and the swing lever body is prevented from swinging upward at the upper surface of the side rising part, and the rear part is facing downward. The swing may be configured to be allowed.

  In this way, by utilizing the structure of the pallet, the upward swing of the rear part of the swing lever body can be suppressed and the downward swing can be allowed, and the pallet holding the rear part on the rear traverse rail is It is possible to easily provide the pallet with a configuration that swings so that the front portion swings downward and falls forward.

  Furthermore, the rocking lever body may have a receiving member of a locking device for holding the upper pallet in the upper storage space at the rear part.

  In this way, by holding the receiving member at the rear part of the swing lever body with the locking device, the swing lever body can also have the function of holding the upper pallet in the upper storage space.

  The elevating means further includes an elevating chain for elevating the upper pallet and the lower pallet, a pulley for elevating the upper pallet by wrapping the elevating chain, and elevating the lower pallet for the elevating chain. The swing lever body may include a pulley, and the upper pallet may be lifted / lowered by the lifting / lowering chain.

  In this way, the upper pallet can be raised and lowered by raising and lowering the pulley built in the swing lever body with the raising and lowering chain, and the configuration for raising and lowering the upper and lower pallets can be made compact. it can.

  According to the present invention, it is possible to suppress an increase in equipment costs required for pits and the like and to stably arrange the falling water from the pallet without splashing the user when placing the pallet on the floor. .

  In addition, by changing the pallet of the “backflow water gradient” of the existing parking device with pits to the front of the “front flow water gradient”, the rear part of the upper and middle pallets has been submerged in the pit. A tall vehicle can be accommodated in the lower pallet, and the number of vehicles that can be accommodated at the conventional pit depth can be increased.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the following description, an elevating and traversing type parking apparatus will be described as an example in which pits are stored in three stages and three rows, and the middle stage is a loading section. Further, the concept of the up / down / left / right direction in the document of this specification and the claims shall be the same as the concept of the up / down / left / right direction in the state of facing the front of the parking apparatus as shown in FIG. The “front side” is defined as the “rear side”.

  As shown in FIG. 1, this multistage elevating and transverse parking apparatus 1 is constructed using a frame assembly 4 framed by a plurality of columns 2 and beams 3 as a skeleton, and has three columns in the vertical direction and three columns in the horizontal direction. A storage space is formed. The upper storage space 5 and the middle storage space 6 are provided on the ground, and the lower storage space 7 is provided in a pit 8 formed by excavating the ground. A driving operation panel 9 is disposed on the left column 2 of the frame assembly 4.

  Three upper pallets 10 are juxtaposed in the upper storage space 5, three lower pallets 11 are juxtaposed in the lower storage space 7, and two upper pallets 11 are in the middle storage space 6. The middle pallet 12 of the table is arranged side by side in the horizontal direction. In the pit multi-stage up-and-down traverse parking apparatus 1, the middle storage space 6 on the ground floor is a loading section 14 that leads to the loading floor 13, and each of the upper pallet 10, the middle pallet 12, It is loaded into and unloaded from the lower pallet 11.

  The upper pallet 10 of the upper storage space 5 can be moved up and down with the middle storage space 6 by an elevating chain 71 driven by an elevating drive unit 70, and the lower pallet 11 of the lower storage space 7 is the same. The lifting / lowering chain 71 can move up and down between the middle storage space 6.

  The middle pallet 12 of the middle storage space 6 is traversed in the left-right direction by the wheels 23 (24) on the traverse rail 21 (22) of the middle storage space 6 by the traverse motor 20. This traversing middle pallet 12 is also referred to as “transverse pallet 12”. The state shown in the figure shows a state in which an empty space for one vehicle is formed at the center of the middle storage space 6. In this empty space, usually, the upper pallet 10 is lowered and arranged, or the lower pallet 11 is raised and arranged.

  As shown in FIG. 2, at the pit opening of the middle storage space 6 (the loading section 14), a front traverse rail 21 on which the front wheels 23 of the middle pallet 12 traverse and a rear side on which the rear wheels 24 traverse. A traverse rail 22 is provided. The relationship between the height position of the front traverse rail 21 and the height position of the rear traverse rail 22 is set as [height position of the front traverse rail 21] <[height position of the rear traverse rail 22]. The upper surface of the rear traversing rail 22 is disposed above the surface of the entry floor 13. As a result, the middle pallet 12 that traverses the wheels 23 and 24 along the front traverse rail 21 and the rear traverse rail 22 is always in a forward-lowering state, and is traversed in a “front flow water gradient” state. The rear traversing rail 22 is a rear placing portion.

  The lower pallet 11 of the lower storage space 7 is stored in a state of being placed on buffer pads 25 and 26 provided on the pit floor 15. In this example, a front bracket 29 that supports the support sprocket 28 of the balance chain 27 provided at the front portion of the lower pallet 11 and a rear bracket 31 that supports the guide sprocket 30 of the balance chain 27 provided at the rear portion. And also serves as a landing means for the lower pallet 11. In this example, the rear bracket 31 is formed higher than the front bracket 29. In the standby state in which the lower pallet 11 is landed, the front bracket is always lowered and becomes a “front flow water gradient”.

  Further, the lower pallet 11 is provided with a lower sprocket 32 on the rear bracket 31 and is moved up and down by an elevating chain 71 driven by an elevating drive unit 70 provided in the frame assembly 4. . The raising / lowering operation of the lower pallet 11 by this raising / lowering drive part 70 is described in description of the upper pallet 10 mentioned later. Further, a balance chain 27 is hung on the lower pallet 11 on the guide sprocket 30 of the rear bracket 31 and the support sprocket 28 of the front bracket 29, and the front end of the balance chain 27 is provided on the frame assembly 4. The horizontal guide plate 33 is fixed to the frame assembly 4, and the rear end portion is fixed to the base plate of the frame assembly 4. By this balance chain 27, the lower pallet 11 is always moved up and down while maintaining the same inclined state.

  In this way, according to the lower pallet 11 and the middle pallet 12 that are kept on standby at the “front flow water gradient”, the accumulated water on the pallet falls as falling water W from the front end of the pallet.

  On the other hand, the upper pallet 10 is illustrated as “rear” shown by a balance chain 36 hung on a support sprocket 35 provided at the front of the pallet and a guide sprocket provided at the rear (not shown in FIG. 2; see FIG. 3). It is stored in the upper storage space 5 with a “flowing water gradient”. The balance chain 36 of the upper pallet 10 has an upper end fixed to the upper part of the frame assembly 4 and a lower end fixed to the lower part (not shown) of the frame assembly 4. The balance pallet 36 allows the upper pallet 10 to be raised and lowered while always maintaining the same inclined state. As described above, according to the upper pallet 10 that is kept in the “backflow water gradient”, the accumulated water on the pallet falls as falling water W from the rear end of the pallet.

  The upper pallet 10 is provided with a swing lever body 50 that protrudes rearward from a side rising portion 41 formed on both sides.

  As shown in FIGS. 3 and 4 (a), the rocking lever body 50 is formed in a U shape in plan view, and the front end portion is formed on both outer sides of the roadway 40 of the upper pallet 10. Provided on the lower surface of the side rising portion 41. The swing lever body 50 is supported by a pivot pin 52 on a pivot member 51 projecting downward from a front position at a predetermined distance from the rear end of the side rising portion 41, and the pivot pin 52. The rear end side can swing around the center. As for the swing of the swing lever body 50, the upward swing is restrained in a state where the upper surface is in contact with the lower surface of the side rising portion 41 (FIG. 4 (a)), and the downward swing is allowed. It has become.

  The swing lever body 50 is provided so as to protrude rearward from the rear end of the upper pallet 10, and a hollow portion having a U-shape in plan view is driven by a support sprocket 76 described later. A pulley 53 and an upper sprocket 54 around which a lifting and lowering chain 71 is wound are pivotally supported. A guide sprocket 55 for guiding the balancing chain 36 of the upper pallet 10 is provided coaxially with the upper sprocket 54. The upper sprocket 54 and the guide sprocket 55 are supported by the same support shaft 56 and rotate integrally. In the figure, the description of the teeth of each sprocket is omitted.

  As described above, the swing lever body 50 is attached in such a manner that upward swinging around the pivot pin 52 is prevented from coming into contact with the side rising portion 41 and only downward swing is possible. . Therefore, when the swing lever body 50 is swung upward and is in contact with the side rising portion 41, the upper pallet 10 can be supported and lifted by the swing lever body 50.

  Further, a locking receiving member 57 projects from the rear end of the swing lever body 50 toward the rear, and a claw member 59 projects from a locking device 58 provided on the frame assembly 4 (fixed side). In this state, the locking receiving member 57 is locked to the claw member 59 so that the upper pallet 10 is held in the upper storage space. The claw member 59 may be integrally formed with the swing lever body 50.

  A landing member 60 is provided at the rear end of the upper pallet 10 so as to protrude rearward. As shown in FIG. 4 (b), the landing member 60 is fixed to the upper pallet 10 with a bracket 61, and the lower surface softens the impact and the like when landing on the rear traverse rail 22. A buffer pad 62 is provided.

  On the other hand, as shown in FIG. 2 described above, the elevating drive unit 70 for elevating the upper pallet 10 and the lower pallet 11 includes an elevating motor 72 provided in the frame assembly 4 and driving of the elevating motor 72. A driven sprocket 74 driven by the sprocket 73; a support sprocket 76 that is rotated around the rotation shaft 75 integrally with the driven sprocket 74; and the lifting chain 71 driven by the support sprocket 76. ing.

  The lifting / lowering chain 71 is wound around a pulley 53, an upper sprocket 54, and a lower sprocket 32 of the lower pallet 11 provided on the swing lever body 50 so as to move the upper pallet 10 and the lower pallet 11 up and down. It is configured. One end of the elevating chain 71 is wound around a pulley 53 provided on the upper pallet 10 and then fixed to the upper frame assembly 4. On the other hand, the other end extends downward from the support sprocket 76, is wound around the lower sprocket 32 provided on the rear bracket 31 of the lower pallet 11, and is then wound on the upper sprocket 54 provided on the upper pallet 10. The end portion extends downward and is fixed to the frame assembly 4.

  According to the elevating drive unit 70, the driven sprocket 74 is driven by the drive sprocket 73 of the elevating motor 72, and the upper stage is driven by the elevating chain 71 driven by the support sprocket 76 that is rotated integrally with the driven sprocket 74. When the pallet 10 is locked in the upper storage space 5, the lower pallet 11 is raised and lowered, and when the upper pallet 10 is unlocked, the upper pallet 10 is raised and lowered.

  Hereinafter, based on FIGS. 5 (a) and 5 (b), a description will be given of the case of entering and leaving the lower pallet 11 in the left column from the state shown in FIGS.

  First, the middle pallet 12 in the left column is traversed to the right from the state shown in FIG. 1, and the middle storage space 6 in the left column becomes an empty space. Next, as shown in FIG. 5A, the elevating motor 72 is driven and the support sprocket 76 is rotated while the lower pallet 10 is kept from being lowered by the locking device 58 at the rear part. The lower pallet 11 in the left row is raised through the lower sprocket 32 on which the lifting chain 71 is hung. At this time, the lower pallet 11 is raised while maintaining the “front flowing water gradient” while maintaining the front and rear inclined state by the balance chain 27. Further, the raising / lowering chain 71 that raises the lower pallet 11 hangs down at a portion of the pulley 53 that is pivotally supported by the swing lever body 50 of the upper pallet 10, and the raised part of the lower pallet 11 is slackened downward.

  The ascent is stopped when the front end of the lower pallet 11 is aligned with the entry floor 13. Thereby, the lower pallet 11 is arrange | positioned at the loading part 14 in the state of "front flow water gradient".

  In this way, the lower pallet 11 is always kept in the “previous flow water gradient” state when stored in the pit, during ascending / descending, and when placed in the loading section 14, so that the falling water W from the lower pallet 11 is maintained. Is discharged from the front end without hitting the user M. Further, since the upper pallet 10 is always in a “backflow water gradient” when the lower pallet 11 is raised and lowered, the falling water W of the upper pallet 10 does not hit the user.

  In FIG. 5A, the elevating chain 71 hung on the pulley 53 pivotally supported by the swing lever body 50 hangs downward from the pulley 53 when the lower pallet 11 is raised. As shown in FIG. 5 (b), the pulley 53 is provided so as to be movable downward from the pivotal support position of the swing lever body 50, so that it can be moved up and down as a movable pulley mechanism (detailed illustration is omitted). Good. By adopting such a moving pulley mechanism, when the lower pallet 11 is raised, the pulley 53 around which the lifting / lowering chain 71 is wound descends while serving as a weight, and the lifting / lowering chain 71 can be smoothly slackened. .

  Next, based on FIG. 6, the case where the loading / unloading with respect to the upper pallet 10 of a left row is performed from the state shown to FIG. 1, 2 mentioned above is demonstrated.

  First, the middle pallet 12 in the left column is traversed to the right from the state shown in FIG. 1, and the middle storage space 6 in the left column becomes an empty space. Next, as shown in FIG. 6, after the claw member 59 is stored by releasing the operation of the locking device 58 that supports the upper pallet 10 at the rear part, the lifting motor 72 is driven to support sprockets. By rotating 76, the upper pallet 10 in the left row is lowered via the pulley 53 (FIG. 2) on which the elevating chain 71 is hung. In this lowering stage, the upper pallet 10 shown in FIG. 2 remains in the state of “backflow water gradient” in which the front and rear inclined states are maintained by the balance chain 36 and the rear end is inclined downward. It is done.

  At the final stage of lowering, the pad 62 of the landing member 60 provided at the rear end of the upper pallet 10 is landed (contacted) on the rear traverse rail 22 to hold the rear portion of the upper pallet 10. . After that, by further continuing the lowering operation, the elevating chain 71 hangs down from the wound pulley 53, and the swing lever body 50 on which the pulley 53 is pivoted swings downward about the pivot pin 52. As a result, the front support sprocket 35 on which the balance chain 36 is hung is lowered, the front end side of the upper pallet 10 is lowered, and the descent stops when the road front end of the upper pallet 10 is aligned with the loading floor 13. (State shown in FIG. 6).

  As a result, the storage state in the upper storage space 5 and the upper pallet 10 that was in the “backflow water gradient” during the lowering are changed to the “front flow water gradient” state in the final stage of being placed in the loading portion 14.

  That is, the upper pallet 10 keeps the state of “backflow water gradient” while waiting for the upper position and during raising and lowering, and the landing member 60 at the rear of the pallet is landed and held on the rear traverse rail 22 at the final lowering stage. After that, the road front end surface of the upper pallet 10 stops in alignment with the entry floor 13 by a slight further lowering operation of the lifting mechanism, so that the slope changes to the “front flow water gradient” for the first time.

  Therefore, since the upper pallet 10 accumulates the falling water as falling water W until it reaches the landing floor 13, the falling water W is not applied to the user M waiting at the loading section 14, and the landing floor 10 13 when the pallet rear part is landed and held, the pallet front part is lowered so as to have a “front flow water gradient”. The user M waiting at 14 can be landed without falling water W.

  As described above, according to the above-described pit multi-stage up-and-down traverse parking device 1, the traverse pallet 12 in the middle storage space 6 and the lower pallet 11 in the lower storage space 7 always discharge the accumulated water from the front end as falling water W. Since the “front flowing water gradient” is inclined, the falling water W can be arranged without falling on the user M waiting in front of the entry portion 14. In addition, the upper pallet 10 in the upper storage space 5 has a “backflow water gradient” inclined so as to discharge the accumulated water as falling water W from the rear end during the ascending standby and during ascent and descent. The water W does not fall on the user M waiting in front of the loading section 14, and the upper pallet 10 that has been the “rear-flowing water gradient” is disposed at the final stage when the water W is disposed in the loading section 14. Since the state changes from the “backflow water gradient” to the “front flow water gradient” in stages, the falling water W can be arranged without falling on the user M waiting in front of the loading section 14.

  Moreover, by arranging the traversing pallet 12 or the upper pallet 10 in the middle storage space 6 as a “front flow water gradient” with the rear part lifted from the surface of the loading floor 13, In the state where the lower pallet 11 arranged with the “flowing water gradient” is stored in the pit 8, the vertical distance between the lower pallet 11 and the transverse pallet 12 or the upper pallet 10 arranged in the middle storage space 6 and the lower pallet 11 is expressed as follows. Since it can be expanded as compared with the prior art, the pit depth L2 can be made shallower than the conventional pit depth L1 by the extent of the rear portion (pit depth; L2 <L1). Therefore, the excavation cost of the pit 8 can be suppressed and the facility cost can be suppressed.

  In addition, in the existing parking device that employs the conventional technique shown in FIG. 8 described above, when remodeling to the configuration of the above-described pit multistage up-and-down traverse parking device 1 with the conventional pit depth (L1), By changing to a configuration in which the swing lever body 50 is provided instead of the fixed bracket 118 (FIG. 9) at the rear part of the upper pallet 10, the “upstream water” is used except when the upper surface of the upper pallet 10 is placed on the loading floor 13. Can be changed to the “front flow water gradient” when the other pallets 11, 12 and the upper pallet 10 are placed on the loading portion 14, and can be modified to the above-described pit multi-stage up-and-down traverse parking device 1 by simple modification. can do. In addition, by modifying the existing parking device in this way to a “front flow water gradient”, even in the case of the conventional pit depth L1, the upper and middle stages of the “rear flow water gradient” described in the prior art are used. The vehicle V that is taller than before can be accommodated in the lower pallet 11 by the height at which the rear portion of the pallet sinks into the pit, and the number of vehicles that can be accommodated can be increased.

  Furthermore, when the vehicle V is put on the traverse pallet 12 or the lower pallet 11, the upper pallet 10 is "backflow water gradient" and the traverse pallet 12 or lower pallet 11 is "front flow water gradient". Since the height between these pallets becomes wider on the entry side, the user can easily go in and out.

  In the above-described embodiment, the pit multi-stage up-and-down traverse parking apparatus 1 in which the middle stage is the entrance part with three stages and three rows has been described as an example.
