As disclosed in JP-A-34468, a lifting drive device is disposed below the passage step in order to effectively use the pit space. In the lifting drive disclosed in this publication, endless drive chains are provided on the support posts before and after the passage step for lifting at two places in the depth direction of the lift body, and each drive chain is provided at a depth of the lift body below the passage step. It is configured to be driven synchronously by a drive shaft having a line shaft shape extending in the direction.

[0003]

However, in the above-described parking apparatus, each pallet of the elevating body is tilted and coupled for discharging rainwater, and the passage steps are tilted so as to match the gradient of each pallet. In this case, it is necessary to dispose a drive shaft in the form of a line shaft extending in the depth direction below the passage step so as not to interfere with the lowered position of the passage step. For this reason, there is a problem that the entire lifting drive device cannot be installed upward so as to fill the space under the passage step, and a dead space is generated below the position where the passage step is raised.

And a lift drive having an endless drive chain that lifts one place of the lift body, wherein the passage step coincides with a gradient of each pallet of the lift body. The lifting drive device is disposed in the lower space on the side of the passage step that is raised high.

Since the lifting / lowering body is maintained in a predetermined posture by the balance chain and one portion of the lifting / lowering body is lifted by the endless drive chain, the lifting / lowering drive device having the endless drive chain is raised to a high step height. It can be placed in one place in the lower space on the side. As a result, the lifting drive device can be arranged so that a dead space below the passage step does not occur, and the height of the entire device can be shortened by a dead space formed below the passage step.

According to a second aspect of the present invention, in the first aspect, each pallet of the elevating body has a backward slope descending from the vehicle entry side to the depth side, and a passage step is performed for each pallet of the elevating body. The whole is formed so as to descend from the entry side to the depth side so as to coincide with the rearward slope, and the elevation drive device is arranged in a lower space on the vehicle entry side of the passage step.

[0008] Since the lifting drive device is arranged in the lower space on the side of the passage step where the vehicle enters, the slope can be made backward without the user getting wet by the rainwater accumulated on the pallet.

The upper pallet 21 is inclined by fixing the one pedestal 27 with bolts via the gradient spacer 28. FIG. 5 shows a structure in which the lower pallet 22 is tilted so as to be adjustable with respect to the vertical support 23. The lower pallet 22 is inclined by fixing the bracket 30 of the upper pallet 21 with a bolt via a gradient spacer 31 under the bracket 29 having a horizontal surface on the side of the support column 23. By changing the thickness of the spacers 28, 31, the inclination angles of the upper and lower pallets 21, 22 with respect to the support 23 can be adjusted.

In FIG. 1, the first balance chain 7
Is a two-row chain hung between the bottom of the pit 3, a pair of double sprockets 32, 33 on both sides in the frontage direction on the entry side below the elevating body 6, and a two-row chain hung between the passage steps 12. The horizontal attitude in the frontage direction of the elevating body 6 which is moved up and down by the elevating drive device 10 is maintained. In FIG. 2, the second balance chain 8 includes a pair of sprockets 34 on both sides of the bottom of the pit 3 and the lower part of the elevating body 6 in the riding direction.

Similarly, the third balance chain 9 is a single-row chain hung between the bottom of the pit 3, a pair of sprockets 36 and 37 on both sides of the lower portion of the elevating body 6 in the riding direction, and the passage step 12. The second balance chain 8,
Numeral 9 jointly maintains the inclined posture of the elevating body 6 which is moved up and down by one elevating drive device 10 in the entry direction. When adjusting the inclination posture of the elevating body 6 by on-site assembly in order to match the inclination of the passage step 5, the length of the second and third balance chains 8, 9 attached to the passage steps 5, 12 should be shortened. By taking advantage of the fact that the inclination of the elevating body 6 becomes smaller and becomes longer when the elongating body 6 becomes longer,
Fine adjustment of the inclination posture of the elevating body 6 can be performed.

The lifting / lowering drive device 10 raises / lowers the lifting / lowering body 6 by one lifting / lowering drive device 10. As shown in FIGS. 1 and 2, in the lower space C on the entry side of the passage step 5, a lifting drive device 10 is provided and provided along a column 16 that supports the passage step 5. ing. Details of the lifting drive device 10 will be described with reference to FIG. The driven shaft 41 of the quadruple sprocket is
16 is supported by a bearing 43a so as to penetrate the web 16a,
The drive shaft 42 of the quadruple sprocket is also supported by bearings 43b so as to penetrate the web 16a of the columns 16,16. The drive shaft 42 has a first deceleration sprocket 4 at one end on the entry side.
4 is inserted into the bracket 45 of the support 16 on the entry side.
A geared motor 46 is fixedly mounted on the motor, a second reduction sprocket 47 is fitted on the output shaft of the geared motor 46, and a reduction chain 48 is wound between the first and second reduction sprockets 44, 47. .

The sprocket having the largest diameter among the sprockets of the drive shaft 42 is a first deceleration sprocket 44. The drive shaft 42 is positioned above the first deceleration sprocket 44 so that the first deceleration sprocket 44 does not hit the lower surface of the passage step 5. At the same time, the drive shaft 42 is moved toward the entry side so that the geared motor 46 does not interfere with the pit 3, thereby effectively utilizing the lower space C of the passage step 5 that is inclined at a rearward slope from the vehicle entry side to the depth side. Also, the sprocket of the driven shaft 43 is lowered to such an extent that the sprocket does not hit the base plate of the column 16. Four rows of endless drive chains 49 are wound around the four sprockets of the drive shaft 42 and the driven shaft 43, and are lifted between the first and second rows and between the third and fourth rows. The pin 50 is fixed. When the lifting pin 50 is located at the near side in the thickness direction of the drawing and moves up and down with the driving of the drive chain 49, the lifting body at the front is moved up and down, and the lifting pin 50 is moved.
Rises and descends in the drawing thickness direction, the elevating body on the rear side moves up and down.

As described above, the drive shaft 4 of the drive chain 49
By effectively arranging the driven shaft 2 and the driven shaft 43 in the space below the passage step 5, the height of the pit type parking device can be reduced. When an intermediate shaft is provided between the deceleration sprockets 44 and 47, the large-diameter deceleration sprocket 44 is provided on the intermediate shaft, and the intermediate shaft and the drive shaft 42 are connected by a sprocket having the same shape as a quadruple sprocket, the drive shaft 42 is connected. By further increasing the height, the height of the device can be shortened, and as a result, the pit depth can be reduced.

FIG. 6 shows a chain hanging state. A hook 51 for the lifting pin 50 of the drive chain 49 is attached to one position of the elevating body 6 on the entry side of the lower pallet 22, and the elevating body 6 is hoisted at this one position.

Therefore, in order to maintain the horizontal posture in the frontage direction, the first balance chain 7 is moved from the pit 3 near the lifting drive device 10 to the passage step 12 to the lower pallet 2.
The lifting force at the position of the hook 51 is transmitted through the first balance chain 7 to the opposite side of the lower pallet 22 in the frontage direction.

In order to maintain a horizontal posture in the inclination direction,
The lower pallet 2 is moved from the pit 3 on the side close to the lifting / lowering drive device 10 to the depth side of the passage step 5.
The lifting force at the position of the hook 51 is transmitted through the second balance chain 8 to the depth side in the direction of entry of the lower pallet 22 via the lower sprockets 34 and 35. The lifting force transmitted to the passage step 12 side of the lifting body 6 via the first balance chain 7 is transferred from the pit 3 on the entry side below the passage step 12 to the depth side of the passage step 12 to the lower pallet 22. The lower balance pallet 22 is transmitted to the depth side of the lower pallet 22 by the third balance chain 9 wound around the sprockets 36 and 37 below the lower pallet 22. In this way, even if one part of the lifting body 6 is lifted, the predetermined inclination posture of the lifting body can be maintained by the balance chains 7, 8, and 9.
