Description

Horizontal circulation type parking device with parking space

Technical Field

The present invention relates to a pallet type horizontal circulation parking apparatus with a parking space, which has a parking space adjacent to an elevator.

Background

The "horizontal circulation type parking device" is a mechanical parking facility that moves a tray on which a vehicle (e.g., a passenger car) is mounted in a horizontal plane to carry out parking and retrieval (parking and retrieval) of the vehicle. The horizontal circulation type parking device includes a lifter for lifting a tray toward a certain height of a shelf for accommodating a vehicle. The elevator is lifted in the lifting path to move the tray horizontally between the shelves. The device is disclosed in patent document 1, for example.

The "parking space" refers to a room isolated from the machine for the purpose of allowing the vehicle to ride on and off the tray.

Fig. 1 is an explanatory diagram of an operation of a conventional general horizontal circulation type parking apparatus 50. In the figure, 5 denotes the elevator position.

Fig. 1 shows the following actions: the vehicle 1 indicated by the symbol "a" (hereinafter, referred to as "vehicle" a ") is horizontally moved to the elevator position 5 in the order of (a), (B), (C), and (D), and is transported to the storage/retrieval section 52 on the floor by the elevator 3. The warehousing-in/warehousing-out of the horizontal circulation type parking apparatus 50 efficiently moves the entire tray horizontally one by one in a traverse (puzzle) manner, thereby moving the tray 53 on which the target vehicle a is loaded to the elevator position 5. Therefore, the horizontal circulation type parking apparatus 50 tends to be as follows: the larger the maximum number of accommodated users is, the longer the waiting time of the user to be put in and out of the warehouse becomes.

In addition, in the conventional horizontal circulation type parking apparatus 50, a loading/unloading unit 52 is provided directly above the ascending/descending path 18 of the elevator 3, and the vehicle 1 travels on a tray 53 held by the elevator 3 by itself directly, and the vehicle 1 is loaded on the tray and unloaded.

Fig. 2A and 2B are explanatory views of a tray 53 of a conventional horizontal circulation type parking apparatus 50. Fig. 2A is a bottom view, and fig. 2B is a longitudinal sectional view of a portion S of fig. 2A.

The bottom surfaces of both longitudinal end portions and both width end portions of the tray 53 used in the horizontal circulation type parking apparatus 50 are formed by horizontally flat square steel pipes 56 extending in the width direction.

Two rails 54 extending in the width direction and two rails 55 extending in the longitudinal direction are provided on the bottom surface of the tray 53 at positions away from the end portions, as shown in fig. 2A. At the intersection of these

rails

54, 55, a switching rail 57 is provided which is rotatable between the width direction and the longitudinal direction.

As shown in fig. 2B, rails 54 extending in the width direction and rails 55 extending in the longitudinal direction cover the square steel pipe 56 and extend from end to end of the tray 53.

Fig. 3A to 3C are explanatory views of a conventional horizontal circulation type parking apparatus 50. Fig. 3A is a side view, fig. 3B is a top view, and fig. 3C is an enlarged view of a portion R of fig. 3A. In the figure, an underground parking facility having two storage areas, an upper storage area and a lower storage area, is described as an example of the horizontal circulation parking facility 50.

As shown in fig. 3B, the rack 7 or the elevator 3 is provided with a conveying device 4 for vertically and horizontally conveying the tray 53. The conveying device 4 supports the

rails

54 and 55 of the tray 53 from below by the rollers 8, and the rollers 8 are provided at four points near the center of the stopped tray 53. The roller 8 rotates while holding the switching rail 57 on which the tray 53 is mounted, and the tray 53 changes its moving direction between the vertical direction and the horizontal direction.

In fig. 3A, the tray 53 stopped on the elevator supports four points near the center from below by the rollers 8. If the vehicle 1 opens into the tray 53 in a state where only these four points are supported, the tires of the vehicle 1 press the end of the tray 53 downward upon opening, and the tray 53 rotates around the rollers 8 as the fulcrum and falls over.

In order to prevent such a situation, as shown in fig. 3C, claw members 51 that support four corners of the tray 53 from below when the vehicle 1 enters the tray 53 are attached to the garage entrance/exit portion 52 of the conventional horizontal circulation type parking apparatus 50.

The claw member 51 is provided so as to move horizontally to be raised and lowered, and horizontally protrudes toward the ascending/descending path 18 of the elevator 3 when the vehicle 1 is ascending/descending, or retreats from the ascending/descending path 18 when the elevator 3 moves. When the four corners of the tray 53 are mounted on the claw members 51, while the claw members 51 are retracted, the tray 53 is lifted upward from the claw members 51 by the lifter 3, and after the claw members 51 are projected to the lifting path 18, the lifter 3 is lowered.

Disclosure of Invention

Problems to be solved by the invention

In recent years, a horizontal circulation type parking apparatus having a large number of maximum storage units has been required.

On the other hand, in the authentication criteria of the mechanical parking apparatus, it is specified that the maximum number of parking facilities to be stored should be set so that each of the parking waiting time and the delivery waiting time is within the time determined by the authentication criteria, and therefore the maximum number of parking facilities is increased only within the range satisfying the certification criteria. In order to increase the maximum number of accommodated parking systems as compared with the conventional horizontal circulation type parking system 50, it is necessary to shorten the time required for parking and retrieving the car as compared with the conventional horizontal circulation type parking system 50 having the same maximum number of accommodated parking systems.

As shown in fig. 3A, in the conventional horizontal circulation type parking apparatus 50, since the loading/unloading unit 52 is located directly above the ascending/descending path 18 of the lifter 3, the lifter 3 cannot be moved while a person is located in the loading/unloading unit, and the operation of the machine and the operation of the vehicle cannot be performed at the same time.

The inventors of the present application considered that the parking space section and the entry space section are separated by providing a dedicated boarding/alighting room (parking space) isolated from a machine (such as an elevator) separately from the elevator 3. If the operation of the machine and the operation of the drive-in can be performed simultaneously, the smoothness of the horizontal circulation type parking apparatus is improved, and the time for warehousing and delivery can be shortened. However, for this purpose, it is necessary to move the tray 53 laterally between the elevator 3 and the berth. Unlike the case where the tray 53 is conveyed to the warehousing/ex-warehouse section 52 directly above the ascending/descending lane 18, the movement of the tray 53 between the elevator 3 and the berth is a horizontal movement that is not movable up and down.

On the other hand, the claw member 51 used in the conventional horizontal circulation type parking apparatus 50 moves horizontally to protrude from the ascending/descending path 18. Therefore, if the claw members 51 are attached to the parking space, the upper surfaces of the claw members 51 may rub against the bottom surface of the tray 53, or the claw members 51 may collide against the side surfaces of the tray 53 that are deflected by the weight of the vehicle 1.

Therefore, means other than the claw member 51 for preventing the tray 53 from falling down when the vehicle 1 is loaded on and unloaded from the tray 53 is necessary in order to provide the parking space adjacent to the lifter 3.

The present invention has been made to solve the above-mentioned problems. That is, an object of the present invention is to provide a horizontal circulation type parking apparatus with a parking space, which can set the parking space at a position adjacent to an elevator even in a horizontal circulation type parking apparatus in which a vehicle is mounted on a tray and moved.

Means for solving the problems

According to the present invention, there is provided a horizontal circulation parking apparatus with a parking space, comprising: a tray for loading a vehicle; a lifter capable of lifting the tray; a berth adjacent to the elevator in the open floor; and a tray conveying device for horizontally moving the tray in the width direction between the elevator and the berth in the opening layer, wherein the tray has a horizontal conveying rail extending horizontally in the width direction on the lower surface of both ends in the length direction, the horizontal conveying rail has a horizontal lower surface continuous over the entire length of the tray in the width direction, and the tray conveying device has a plurality of support rollers provided at least at the berth, positioned at intervals in the width direction, and supporting the horizontal lower surface of the horizontal conveying rail of the tray.

ADVANTAGEOUS EFFECTS OF INVENTION

According to the present invention, the elevator includes a berth adjacent to the elevator in the opening stage, and has a horizontal lower surface extending in the width direction over the entire length of the bottom surface of both end portions in the longitudinal direction of the tray, and the horizontal lower surface is supported from below by at least the support roller of the tray conveying device provided at the berth.

Thus, even if the tray does not move up and down during the lateral movement at the opening level, both end portions of the tray during the ascending and descending can be supported from below by the support rollers, and thus the tray can be prevented from falling over during the ascending and descending.

Therefore, since the parking space can be provided at a position deviated from the elevator in the horizontal direction, the partition of the parking space and the partition of the entry space can be separated, and the smoothness of the horizontal circulation type parking apparatus with the parking space can be improved.

Further, since the partition of the parking space and the partition of the entry space are separated, the operation of the machine and the entry operation can be performed simultaneously. Thus, since the devices in the parking space can be continuously operated even while the user is entering and leaving the parking space, the time required for entering and leaving the parking space can be shortened as compared with a conventional horizontal circulation type parking apparatus having the same maximum number of accommodated devices.

Therefore, according to the present invention, the maximum number of horizontal circulation type parking apparatuses with parking spaces that satisfy the certification standards can be increased as compared with the conventional horizontal circulation type parking apparatuses.

Detailed Description

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, the same reference numerals are used for the common portions in the drawings, and redundant description is omitted.

(first embodiment)

Fig. 4A is a side view of the horizontal circulation type parking apparatus with a parking space 10 of the first embodiment, and fig. 4B is a plan view of a storage area thereof. Fig. 4C is an enlarged view of the portion R of fig. 4A. Fig. 4A to 4C illustrate an underground parking system having two storage areas, an upper storage area and a lower storage area, as an example of the horizontal circulation parking system 10 with a parking space.

A parking space-equipped horizontal circulation type parking apparatus 10 (hereinafter, simply referred to as "parking apparatus 10") is a mechanical parking facility that moves a tray 2 on which a vehicle 1 is loaded in a horizontal plane to carry out parking and retrieval (parking and retrieval) of the vehicle 1.

The vehicle 1 is, for example, a passenger car. The vehicle 1 is a small-sized vehicle, a medium-sized vehicle, a large-sized vehicle, a high-top vehicle, or the like.

Further, the parking apparatus 10 includes the lifter 3. In fig. 4A and 4B, a vertically extending elevator shaft 18 is provided between the above-ground opening floor 11 and the above-ground and below-ground floors of the elevator 3. The elevator 3 for loading the tray 2 is lifted and lowered in the lifting path 18, and moves the tray 2 horizontally between the shelf 7 and the elevator.

In the example of the figure, the canopy 7 provided adjacent to the ascending/descending path 18 has two upper and lower decks. In this example, in each of the upper and lower floors (storage areas), there are 11 vehicle storage spaces in the range other than the position where the elevator 3 raises and lowers the tray 2.

In the figure, a plurality of conveying devices 4 are horizontally fixed to each layer of the shelf 7, and the conveying devices 4 move the tray 2 of the loading vehicle 1 in the width direction and the longitudinal direction thereof. The conveying device 4 is configured to be capable of performing both "lateral conveyance" in which the tray 2 of the loading vehicle 1 is moved in the width direction thereof and "longitudinal conveyance" in which the tray is moved in the longitudinal direction thereof.

The transport devices 4 are provided one in each vehicle storage space. Each of the conveying devices 4 corresponds to the size of the tray 2 in a plan view.

As shown in fig. 4B, the parking apparatus 10 of the present embodiment includes a plurality of pallets 2. In each of the upper and lower stages, the plurality of conveyance devices 4 are disposed at a predetermined interval from each other and are horizontally supported at four corners thereof. In each layer, tray 2 is not loaded on at least one of the conveying devices and becomes an empty unit, and tray 2 is loaded on the other conveying device.

With the above-described configuration of the parking apparatus 10, since at least one of the conveying devices 4 is an empty unit in each floor, the tray 2 on the conveying device adjacent to the empty unit can be horizontally moved (horizontally conveyed or vertically conveyed) on the empty unit. The horizontal movement causes the cell to move to a position adjacent to the position of the empty cell.

Therefore, by repeating this operation, the tray 2 of each layer can be freely moved horizontally (horizontally or vertically).

With this configuration, the tray 2 moves horizontally in the width direction and the longitudinal direction on each layer of the shelf 7. Thus, the shortest parking/retrieval route is determined by the computer control of the horizontal movement of the tray 2 in the parking device 10, and the vehicles 1 are efficiently moved horizontally one by one in the manner of lifting and moving laterally, thereby realizing the shortest waiting time for parking/retrieval.

Fig. 5A to 5E are explanatory views of the tray 2 of the parking apparatus 10 according to the present embodiment. Fig. 5A is a bottom view.

The tray 2 of the present embodiment has a width direction rail 15, a length direction rail 16, and a switching rail 17 on its lower surface.

The width-direction rail 15 is a rail extending horizontally in the width direction along the top plate 2a, and the length-direction rail 16 is a rail extending horizontally in the length direction along the top plate 2 a.

The switching track 17 is a track located at an intersection of the width direction track 15 and the longitudinal direction track 16 and configured to be rotatable between the width direction and the longitudinal direction.

The tray 2 has a lateral conveying rail 14 extending horizontally in the width direction on the lower surface of both end portions in the longitudinal direction thereof. The lateral conveying rails 14 may be, for example, square steel pipes that receive the load of the vehicle 1. The lateral conveying rails 14 are disposed further outside than the longitudinal rails 16. In other words, the longitudinal rail 16 has one end on the longitudinal inner side of the tray 2 with respect to the lateral conveying rail 14, and extends from the one end toward the longitudinal center.

As described with reference to fig. 2A and 2B, in the tray 53 of the conventional horizontal circulation type parking apparatus 50, the lower surfaces of both longitudinal end portions are divided by the rail 55. Therefore, the tray 53 cannot be conveyed by the support rollers 13a.

With the above configuration, the parking apparatus 10 according to the present embodiment can have the horizontal lower surfaces 14a continuous over the entire length in the width direction on the lower surfaces of both ends in the longitudinal direction of the tray 2. Therefore, the parking device 10 loads the plurality of support rollers 13a of the tray conveying device 13 on the horizontal lower surface 14a to laterally move the tray 2, and supports both longitudinal end portions of the tray 2 when the vehicle 1 is ascending and descending.

Fig. 5B is a longitudinal sectional view of a T portion of fig. 5A, and fig. 5C is an enlarged view of the T portion of fig. 5A. Tapered members having a decreasing width and thickness are provided at the ends of the longitudinal rails 16 located at both longitudinal ends of the tray 2. This enables smooth transition to the adjacent roller 8 even if the longitudinal end of the tray 2 is bent downward.

Fig. 5D is an enlarged view of a U portion of fig. 5A, and fig. 5E is a view from G-G of fig. 5D.

As shown in these figures, at both end portions of the lateral conveying rail 14, tapered portions 14b whose width and thickness are reduced are provided. This reduces noise when transferring to the next support roller 13a, and allows the tray 2 to smoothly move in the lateral direction.

Fig. 6A and 6B are explanatory views of the roller 8 of the conveying device 4. Fig. 6A is a side view, and fig. 6B is a top view.

The conveying device 4 has the rollers 8 at four points (at positions below the switching rails 17) near the center of the stopped tray 2. The roller 8 includes a driving roller 8a, a guide roller 8b, a vertical rotation shaft 8c, and a motor 8d.

The driving roller 8a is a roller that rotates around a horizontal rotation axis, and supports the bottom surfaces of the

rails

15, 16, and 17 of the tray 2 on the side surfaces thereof.

The guide rollers 8b are provided with at least four floating rollers that rotate around vertical rotation axes on the side surfaces of the

rails

15, 16, and 17 above the drive roller 8 a. The drive roller 8a and the guide roller 8b are integrally configured to be rotatable about a vertically extending vertical rotation axis 8 c. The driving roller 8a and the guide roller 8b rotate the driving roller 8a between the width direction and the longitudinal direction while holding the side surface and the bottom surface of the switching track 17 therebetween. In addition, the motor 8d rotates the drive roller 8 a.

With the configuration of the roller 8, the conveyance device 4 loads the

rails

15, 16, and 17 on the driving roller 8a with the side surfaces of the

rails

15, 16, and 17 sandwiched by the guide roller 8b, and moves the tray 2 in the vertical direction and the horizontal direction by driving the motor 8d.

When the rollers 8 of the conveying device 4 are mounted on the driving rollers 8a while sandwiching the switching rail 17 by the guide rollers 8b, the switching rail 17 can be rotated by rotating about the vertical rotation axis 8c, and the moving direction of the tray 2 can be switched between the vertical conveyance and the lateral conveyance.

Fig. 7 is a plan view of the parking apparatus 10 according to the present embodiment when the vehicle 1 enters and exits the entrance floor 11.

The parking apparatus 10 of the present embodiment includes a parking space 12 on an entrance floor 11 at a position horizontally displaced from the elevator 3 in the width direction of the pallet 2.

The berth 12 is a dedicated boarding/alighting room isolated from equipment such as the elevator 3. As shown in the figure, the berth 12 is provided adjacent to the elevator 3 in the open floor 11.

As shown in the drawing, when the vehicle 1 is loaded or unloaded, the tray 2 is disposed at the center of the berth 12, and the floor 19 surrounds the tray 2. An entrance door 6a that opens and closes automatically is provided at the entrance of the berth 12. The vehicle 1 passes through the doorway and drives by itself to the pallet 2 set at the setting position of the parking place 12.

Between the berth 12 and the elevator 3, there is a partition door 6b that opens and closes automatically. The partition door 6b is closed while a person is located at the parking space 12, separates the parking space 12 from a machine such as the elevator 3, and is opened when the pallet 2 travels in the lateral direction, so that the pallet 2 and the vehicle 1 pass between the parking space 12 and the elevator 3. Thus, the parking apparatus 10 according to the present embodiment can separate the partition of the parking space in which the lifter 3 or the rack 7 and the conveyance device 4 are present and the partition of the open space in the parking space when the vehicle 1 is ascending and descending, and thus can improve the smoothness of the parking apparatus 10.

Fig. 8 is a plan view of the parking apparatus 10 according to the present embodiment when the tray 2 of the entrance stage 11 travels in the lateral direction. In the figure, the tray 2 is shown by a broken line.

The parking apparatus 10 of the present embodiment includes a tray conveying device 13.

The tray conveying device 13 is a device for horizontally moving the tray 2 in the width direction between the elevator 3 and the berth 12 in the opening layer 11. The tray conveying device 13 includes a plurality of support rollers 13a provided on both the elevator 3 and the berth 12 and positioned at intervals in the width direction. The rotation axis of the support roller 13a extends in the longitudinal direction of the tray 2. The tray conveying device 13 provided in the berth 12 is provided below the floor 19 of the berth 12, and the support rollers 13a are exposed from the floor 19 of the berth 12 toward the installation position of the tray 2.

The plurality of support rollers 13a of the tray conveying device 13 are configured to be at least partially rotatably driven, and convey the tray 2 in the width direction while supporting the lateral conveying rails 14 of the tray 2 from below.

Further, a floor between the berth 12 and the elevator 3 becomes a movable floor 9, and a tray conveyance device 13 is also provided below the movable floor 9. When the pallet 2 travels in the lateral direction, the movable floor 9 can be lowered downward, and the support rollers 13a are exposed above the movable floor 9 from the openable and closable opening 9a of the movable floor 9.

In this way, the tray conveying device 13 provided in both the berth 12 and the elevator 3 forms two rows of support rollers 13a aligned in a straight line with a gap from the berth 12 to the elevator 3.

A center roller 13b having a shape similar to that of the roller 8 of the conveying device 4 is provided at the center of the elevator 3 and the center of the position where the tray 2 is installed in the berth 12, and at the position where the switching rail 17 exists in the tray 2 during the boarding and alighting of the vehicle 1. Unlike the roller 8 of the conveying device 4, the center roller 13b does not have a vertical rotation axis 8c, and the direction of the rotation axis of the center roller 13b is fixed to the longitudinal direction of the tray 2. Accordingly, the direction of the switching rail 17 of the tray 2 can be fixed to the same direction as the width direction rail 15 during the reciprocating movement from the rack 7 to the berth 12.

The tray conveying device 13 includes an actuator 13c serving as a power for moving the tray 2 in the lateral direction. The actuator 13c of the present embodiment is provided on the support roller 13a. For example, the actuator 13c of the example of fig. 8 is a motor, but is not limited thereto.

Fig. 9A and 9B are longitudinal sectional views of a portion T of fig. 5A. Fig. 9A is a view when the tray 2 is longitudinally conveyed on the shelf of the parking space, and fig. 9B is a view when the tray 2 travels laterally between the lifter 3 and the berth 12 in the opening stage 11.

As shown in the figure, the horizontal lower surface 14a of the lateral conveyance rail 14 is disposed above the lower surfaces of the width direction rail 15, the length direction rail 16, and the switching rail 17. The horizontal lower surface 14a is also provided above the rollers 8 of the conveying device 4.

Thus, even if the longitudinal rail 16 and the lateral conveying rail 14 are located at positions close to each other, the tray 2 can be conveyed along the longitudinal rail 16 and the tray 2 can be conveyed along the lateral conveying rail 14 separately by changing the heights of the

rails

14 and 16.

That is, the conveyance device 4 rotates the driving roller 8a while holding the side surfaces and the bottom surfaces of the

rails

15, 16, and 17 of the tray 2 between the driving roller 8a and the guide roller 8b, and horizontally moves the tray 2 by conveying the

rails

15, 16, and 17 forward and backward. When the roller 8 reaches the longitudinal end of the tray 2, the horizontal lower surface 14a of the lateral conveyance rail 14 is located above the upper surface of the guide roller 8 b. In addition, when the lateral conveying rail 14 is positioned directly above the roller 8, the tray 2 is horizontally supported by the other roller 8, and thus the lateral conveying rail 14 can pass over the roller 8 without contacting the roller 8.

On the other hand, the rotary shaft 13d of the support roller 13a of the tray conveying device 13 is a cantilever rotary shaft having a root portion on the outer side in the longitudinal direction of the tray 2 and extending in the longitudinal direction. The thickness of the support roller 13a is smaller than the width of the lateral conveying rail 14. Therefore, the tray 2 can be made to travel laterally in the open layer 11 without bringing the support roller 13a into contact with the longitudinal rails 16.

In this way, even if the end of the longitudinal rail 16 is in contact with the side of the lateral transport rail 14, the longitudinal rail 16 and the lateral transport rail 14 can be used separately for the longitudinal transport between the sheds and the lateral travel movement into the floor 11.

With this configuration, the parking apparatus 10 according to the present embodiment can support the longitudinal end of the tray 2 from below when the vehicle 1 is loaded and unloaded, even if the tray 2 is moved only horizontally between the lifter 3 and the berth 12.

Further, since the actuator 13c is attached to the support roller 13a, the tray conveying device 13 can have both a function of a supporting device at both ends in the longitudinal direction of the tray and a function of a transverse traveling device of the tray 2.

(second embodiment)

Fig. 10 is a plan view of the parking apparatus 10 according to the second embodiment when the tray 2 of the entrance stage 11 travels in the lateral direction. In the figure, the tray 2 is also shown by a broken line.

The parking apparatus 10 of the present embodiment is different from the first embodiment in that the actuator 13c of the tray conveying device 13 is provided on the center roller 13b.

The support rollers 13a according to the present embodiment may be provided only at the installation position of the tray 2 in the berth 12, as long as they can support the longitudinal ends of the tray 2 when the vehicle 1 is ascending and descending.

However, the present invention is not limited to this, and the support rollers 13a may be provided in order to assist the travel of the pallet 2 in a place where the distance between the center rollers is widely opened (for example, in the vicinity of the movable floor 9 in fig. 10) like the support rollers 13a provided in the lifter 3 in fig. 10. Thus, even in a place where the number of the center rollers 13b contacting the longitudinal rails 16 is small, the tray 2 can be supported by the center rollers 13b and the support rollers 13a, and thus the tray 2 can be stably conveyed.

In this way, the parking apparatus 10 of the present embodiment causes the tray 2 to travel laterally by rotating the center roller 13b. The support roller 13a freely rotates as a floating roller.

The center rollers 13b are not arranged as densely as the support rollers 13a. Therefore, as long as the interval at which the center rollers 13b are arranged is larger than the width of the movable floor 9, the opening 9a through which the center rollers 13b protrude above the movable floor 9 may not be provided in the movable floor 9 as shown in fig. 10. Further, even when the width of the movable floor 9 is larger than the interval at which the center rollers 13b are arranged, the number of the openings 9a can be reduced.

Further, (1) the configuration of the center roller 13b is similar to that of the roller 8 of the conveying device 4, (2) the actuator 13c is not required for the support rollers 13a, and (3) the number of the support rollers 13a can be reduced, so that the manufacturing cost of the parking device 10 can be expected to be reduced as compared with the first embodiment.

The configuration and effects of the parking apparatus 10 according to the other embodiment are the same as those of the first embodiment.

According to the present invention described above, the opening floor 11 is provided with the berths 12 adjacent to the lifter 3, and the bottom surfaces at both ends in the longitudinal direction of the tray 2 have the horizontal lower surfaces 14a extending in the width direction and continuing over the entire length of the tray 2. Preferably, the horizontal lower surface 14a is supported from below by support rollers 13a of the tray conveyance device 13 provided from the elevator 3 to the berth 12.

Thus, even if the tray 2 does not move up and down during the lateral travel at the opening stage 11, both end portions of the tray 2 during the ascending and descending can be supported from below by the support rollers 13a, and thus the tray 2 can be prevented from falling over during the ascending and descending.

Therefore, since the berth 12 can be provided at a position deviated from the elevator 3 in the horizontal direction, the smoothness of the horizontal circulation type parking apparatus 10 with a berth can be improved by dividing the partition of the parking space and the partition of the entry space.

Further, since the partition of the parking space and the partition of the parking space are separated, the parking apparatus 10 with a parking space can perform the operation of the machine and the operation of the parking space at the same time. Accordingly, since the devices in the parking space can be continuously operated even while the user is entering and leaving the parking space, the time required for entering and leaving the parking space can be shortened as compared with the conventional horizontal circulation type parking apparatus 50 having the same maximum number of accommodated devices.

Therefore, according to the present invention, the maximum number of the horizontal circulation type parking apparatuses 10 with berths that satisfy the certification standards can be increased as compared with the conventional horizontal circulation type parking apparatus 50.

The present invention is not limited to the above-described embodiments, and various modifications can be added within a range not departing from the gist of the present invention.
