However, in the conventional device having this configuration,
Holding frame 102 for holding motor 101 and wire drum 109
Because of the arrangement in the rear frame 102b, an extra depth space for arranging them in the vehicle storage section had to be taken.

According to the present invention, when a sufficient depth space can be ensured, the configuration can be the same as that of the conventional apparatus described above. However, when it is necessary to make the depth space as small as possible, for example, FIG. As shown, holding frame
A geared motor 32 with a brake, which is a third driving means, is fixed to the rear of one of the side frames 22d, and a sprocket 42 is fixed to its rotating shaft 41. The sprocket 42 is positioned above the rear frame 22b of the holding frame 22. A first drive shaft 33 along the axis of the first drive shaft 33 is horizontally mounted, and a sprocket 44 interlocking with a sprocket 42 of the motor 32 via a loop-shaped chain 43 is fixed to one end of the first drive shaft 33. Two sprockets 34, 35 each having the same radius of rotation are fixed to both ends of the second pallet 23, and first and second lifting chains 36 and 37 are connected to the front and rear portions on both sides of the second pallet 23 by bolts or the like. One end is fixedly connected to each other by means 38 (see FIGS. 8 and 9), and these chains 36 and 37 are, for example, idlers or the like disposed on the side frames 22c or 22d of the holding frame 22 located above each one end. Around the first turning means 39,40, Over turning sprockets 34, 35 of the first drive shaft 33 corresponding Re respectively, it is preferable to rotatably constituting the first drive shaft 33 in the forward and reverse two directions.

Therefore, if this configuration is adopted, the motor 32 is disposed on the side frame of the holding frame, which is a space that does not obstruct, and it is not necessary to dispose a wire drum using a chain instead of a wire. By doing so, it is not necessary to provide an extra depth space for disposing a wire drum or the like in the second vehicle storage portion, and further space saving can be achieved.

In place of the wire 108, first and second
When the above configuration using the lifting chains 36 and 37 is adopted, when the second pallet 23 is raised, the first and second
The hoisted portions of the hoisting chains 36 and 37 hang down, and if the length of the hangdown is long, the chain may be hooked on other surrounding members, resulting in equipment failure.

For this reason, in order to prevent the chain from sagging, a chain bag for accommodating the hanging chain may be arranged below the sprocket. Preferably, as shown in FIG. 2nd lifting chain
One of the sprockets 34 and 35 is wrapped around the sprockets 34 and 35 from below, and the other ends of the first and second lifting chains are connected to one end of the connecting member 45, and one extending from the other end of the connecting member 45 Is extended around the second direction changing means 81, 81 provided on the side frames 22c and 22d of the holding frame 22, and then connected to a predetermined portion of the first lifting chain.

With this configuration, it is possible to prevent the wound portions of the first and second lifting chains 36 and 37 from hanging down when the second pallet 23 is raised.

The position of the second diverting means 81 and the connecting member 45, and the predetermined portion of the first lifting chain 36 connecting the extension chain 46 are determined by the range of elevation of the second pallet 23 and the second pallet. Because it changes depending on the position where the first and second lifting chains 36 and 37 are connected to 23, etc.
It can be appropriately determined according to the configuration of each device.

As shown in FIG. 1, the third vehicle storage section 4
The basic position is the basement second floor position C, and the third pallet 47 which can move up and down in the arrow direction 70 between this position C and the first floor position A above the ground.
In addition, the fourth vehicle storage unit 5 has a base position 1 underground.
The fourth pallet 49 at the floor position D, which is fixedly connected to the third pallet 47 via the connecting member 48 and which can move up and down between the first basement floor position D and the second floor position B above and below as the third pallet 47 moves up and down.
Having.

As means for raising and lowering the third and fourth pallets 47 and 49, for example, as shown in FIGS.
Two second pillars 51a, 51b are fixed to the pit bottom surface position 50 on both sides of the pallet 47, and between the front and rear pillars 51a, 51b located on one side of the third pallet 47, among these pillars, A sprocket 56 connected via a loop-shaped chain 60 to a geared motor 52 with a brake, which is a fourth driving means fixed to one of the columns 51a, and sprockets 54 and 55 provided at both ends and having the same rotational radius. The second drive shaft 53 to which is fixed
The first rotators 57a to 57d such as sprockets are disposed at the front and rear sides on both sides below the third pallet 47, and the third rotator interlocking therewith is provided around the sprockets 54 and 55. And the fourth lifting chains 58 and 59, respectively, and the chains 58 and 59 are wound around the first rotating bodies 57a and 57b and 57c and 57d, respectively, and one end of the chains 58 and 59 is palette
The second drive shaft 53 may be configured to be rotatable in two forward and reverse directions by being fixedly connected to upper and lower positions of the front and rear supports located on the other side of 47 and to a position 64 near the ground.

That is, by driving the motor 52 to rotate the second drive shaft 53, the third and fourth lifting chains 58,5
9, the third pallet 47 can be raised, and the fourth pallet 49 can be raised at the same time. On the other hand, if the second drive shaft 53 is rotated in the opposite direction, The third pallet 47 can be lowered.

Therefore, by adopting this configuration,
The third and fourth pallets 47, 49 can be moved up and down by one driving means 53, and there is no need to provide a driving means for each pallet 47 or 49, so that the manufacturing cost of the apparatus and the cost of electricity can be reduced, Installation workability is also improved.

The sprocket 54 or 55, the first rotating bodies 57a, 57b or 57c, 57d, and the lifting chain 58 or 59 are provided. One end of the chain 58 or 59 is fixed, and the other end is wound. In this case, as shown in FIG. 11, the first rotating body 57a or 57c located on the winding side wants to move to the dotted line position, while the first rotating body 57b or 57d located on the opposite side to the winding side is There is a tendency to stop at the same position, and as a result, there is a case where the parallel balance of the third pallet 47 when the third pallet 47 is moved up and down cannot be reliably maintained.

Therefore, in this case, as shown in FIG. 10, at least one of the front part and the rear part below the third pallet 47 (only the front part in FIG. 10) and at least the second part
The first rotating body 57a disposed on the drive shaft 53 side (only the second drive shaft 53 side in FIG. 10) is moved from the third pallet 47 in the front-rear direction 14 thereof.
, And first and second sprockets 62a and 62b fixed to both ends thereof, respectively, and the lifting chain 58 is fixed to the first sprocket 62a and the third sprocket 62a fixed to one end of the rotary shaft 61a. The pallet 47 is wound around a first rotating body (for example, a sprocket) 57b located on the other side of the pallet 47, and the first rotating body 57b is moved together with the first rotating body 57b to rotate the first sprocket 62a forward or backward. The third pallet 47 is raised or lowered to make the radius of rotation of the second sprocket 62b fixed to the other end of the rotary shaft 61a the same as the radius of rotation of the first sprocket 62a, and extend vertically and both ends 63a, 63b are Third
The timing chain 63, which is fixedly connected above and below the lifting range of the pallet 47, is connected to the second sprocket.
When the first sprocket 62a rotates forward or backward by meshing with the first sprocket 62b, the second sprocket 62b rotates by the same amount as the first sprocket 62a, and the second sprocket 62b moves by a distance corresponding to the amount of rotation. Timing chain
More preferably, it is configured to move vertically up or down along 63.

That is, with this configuration, the second sprocket 62b rotates by the same amount as the first sprocket 62a,
The sprocket 62b moves vertically upward or downward along the timing chain 63 by a distance corresponding to the amount of rotation, and accordingly, as shown in FIG. The tendency of the pallet 47 to rotate by a rotation amount larger or smaller than the proper rotation amount corresponding to the elevating distance of the pallet 47 is prevented by the accurate movement of the second sprocket 62b, and the first sprocket 62a is always rotated by the proper rotation amount. , So that the parallel balance of the pallets when the third pallet 47 is raised and lowered can be reliably maintained.

FIG. 17 is a view from the front of the third pallet 47 in order to clarify the arrangement of the timing chain 63 and the second sprocket 62b mounted below the third pallet 47. In FIGS. 10 and 17, in order to securely hold the parallel balance in the width direction of the third pallet 47, only one balance holding device including the timing chain 63 is provided for each third pallet. Although the case where it is shown is shown, for example, this balance holding device is
If the third pallet 47 is disposed on the other first rotator 57b, the parallel balance in the width direction of the third pallet 47 can be maintained more reliably. Then, the parallel balance in the front-rear direction of the third pallet 47 can be reliably held, so that the number of the balance holding devices can be appropriately increased or decreased as needed.

In these figures, the second sprocket
In order to ensure that the timing chain 63 meshes with the second sprocket 62b at the upper and lower positions of the timing chain 63, the timing chain 63 is pressed against the second sprocket 62b so that a certain tension acts on the timing chain 63. Although the case where guide means 79a, 79b (for example, a sprocket) is provided is shown, the guide means 79a, 79b can be provided as needed.

As shown in FIG. 10, two adjacent third pallets 47a and 47b are connected to one motor as shown in FIG.
It is useful to raise and lower only by 52.

As a conventional apparatus having a mechanism for raising and lowering two adjacent pallets 113a and 113b by one motor,
For example, there is one disclosed in Japanese Patent Publication No. 3-7784 filed earlier by the present applicant. This device, as shown in FIG.
The chain 112 is turned around the sprocket 111 fixed to the drive shaft 110 linked with one drive motor,
The chain 112 hanging on both sides of the pallet 111 is turned around the rotating bodies 114a and 114b provided on the end face of the pallet, and
2 is fixedly connected to a sidewalk 115 provided between the pallets 113a and 113b. By rotating the sprocket 111 in two forward and reverse directions, both pallets 113a and 1b are rotated.
13b can be raised and lowered by one motor.

However, in the conventional device having this configuration,
Since both ends of the chain 112 had to be fixedly connected to the sidewalk 115, the installation width W of the sidewalk had to be set to some extent.

According to the present invention, if the frontage space can be sufficiently secured in the lateral direction 6, the configuration can be the same as that of the above-described conventional device. However, if the frontage space needs to be reduced as much as possible, For example, as shown in FIG. 10 and FIG. 14, the motor 52 and the second drive shaft 53 are disposed on the column between two adjacent third pallets 47a and 47b, and the third and fourth lifting members are provided. Connect both ends of chains 58 and 59
The third pallets 47a and 47b are fixedly connected to the upper and lower positions of the front and rear supports located on the outer side of the third pallets 47a and 47b, respectively, or to a position 64 close to the ground. It is preferable that the installation width W of the sidewalk 69 located between the pallets 47a and 47b be adjusted.
Can be narrowed, thereby further saving space.

Therefore, according to this configuration, the two adjacent third pallets 47a and 47b can be moved up and down by one driving means 53, and the third pallets 47a and 47b can be moved up and down.
Since it is not necessary to provide a driving means for each b, the manufacturing cost and the electricity cost of the device are further reduced, and the installation workability is further improved. Further, space saving in the lateral direction 6 of the parking device can be achieved.

It should be noted that two adjacent third pallets 47a and
47b, the third and fourth hoist chains 58, 59 are wound when the third and fourth hoist chains 58, 59 are hoisted.
If the chain portions 58a and 59a hang down too long, the chain portions 58a and 59a may be caught by surrounding members or the like and cause a device failure.

Therefore, when such a situation is assumed, as shown in FIGS. 10 and 12, the third and fourth lifting chains 58, 59 are attached to the central portion 65 outwardly from both side surfaces thereof. At least one protruding chain hanger 66 is provided, and a central portion 65 of the chain wound up and dropped off by the sprockets 54 and 55 is provided at a position below and adjacent to the sprockets 54 and 55 fixed to the second drive shaft 53. Chain hanger support bracket 67 supported via hanger 66
Is preferably provided.

Therefore, with this configuration, the wound portions of the third and fourth lifting chains 58 and 59 can be folded and aligned by the chain hanger support fitting 67, and as a result, the chain portions 58a and 59a can be separated. The sagging length is shortened, and the device is less likely to fail due to being caught by surrounding members or the like.

As described above, in the present invention,
In particular, since the third pallet 47 and the fourth pallet 49 are integrally lifted and lowered, the number of installations of the third and fourth vehicle storage units is set to N (N ≧ 2, where N is an integer). ), The number of each of the first and second vehicle storage units was N-1.

That is, the number of each of the first vehicle storage section 2 and the second vehicle storage section 3 (one each in FIG. 1) is changed to the number of the third vehicle storage section 4 and the fourth vehicle storage section 5 ( (In Fig. 1 each two)
The reason is that the third pallet 47 and the fourth pallet 49 having an integral structure cannot be raised to the ground surface position unless the number is reduced by one.

Next, an example of a series of operations of the parking device of the present invention will be described. Operation is performed by the operation panel provided on the front of the device.
The operation panel 80 is provided with operation keys numbered from 0 to 9 and an emergency stop button. When the apparatus is stopped, the first to fourth vehicle storage units 2 to 2 are provided. 5 is at the basic position shown in FIG.

When a vehicle is to enter or leave the first to fourth pallets 7, 23, 47, and 49, the target pallet number is input using the operation keys, and the target pallet is moved to the first floor position on the ground. Then, the vehicle can be moved in and out by opening the safety fence 68.

First, at the basic position shown in FIG.
When the vehicle is moved in and out of the first pallet 7 of the vehicle storage section 2, the vehicle can be moved in and out simply by opening the front safety fence 68 without any movement of the device.

Next, at the basic position shown in FIG.
When the vehicle is to be put in or taken out of the second pallet 23 of the vehicle storage section 3, the first pallet 7 located below the second pallet 23 is moved in the lateral direction (left direction in FIG. The pallet 23 is moved to the first floor position above the ground, and the safety fence 68 is opened so that the vehicle can be moved in and out.
