DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pallet tilting device in a parking facility having a lifting pallet, in which the tilt of the lifting pallet is changed between a riding position and a storage position.

[0002]

2. Description of the Related Art In a mechanical parking facility provided with an elevating pallet, when storing a vehicle, the vehicle is loaded on the elevating pallet at a loading position, and the elevating pallet is moved up and down to the storage position. When the lifting pallet is stored in the upper storage position, in order to prevent rainwater from dripping from the tip of the lifting pallet, and to prevent the user from feeling uneasy that the vehicle may fall, It is desirable that the elevating pallet be inclined up front so that the tip is slightly upward.

On the other hand, when the lifting pallet is in the riding position, it is desirable that the lifting pallet has a slightly downward slope with its tip slightly downward in order to facilitate entry of the vehicle. However, it is difficult to satisfy these requirements at the same time, and if the posture of the lifting pallet is set to the forward-downward inclination, the vehicle can be easily boarded at the boarding position, but rainwater dripping occurs at the storage position, And,
When giving the user an uneasy feeling as if the vehicle is dropping, conversely, if the posture of the lifting pallet is set
Although rainwater dripping can be prevented and the user does not feel uneasy as if the vehicle is falling, it is difficult for the vehicle to get on the lifting pallet at the riding position.

Therefore, in a parking facility having a cantilever type lifting pallet, as shown in FIG. 4, tapered blocks 44 and 45 are respectively provided on a front edge 42 and a rear edge 43 of a column 41 erected at the rear. The upper rolling wheel 47 and the lower rolling wheel 48 pivotally supported by the lifting frame 46 are brought into contact with the tapered blocks 44, 45 when the lifting pallet is raised, so that the lifting pallet 49 is raised forward at the storage position shown by the solid line. There has been proposed a tilting device for a lifting pallet of parking equipment in which the pallet is inclined forward and the pallet is lowered forward at a riding position indicated by a chain line (see Utility Model Registration No. 3013632).

[0005]

However, a so-called 4 is constructed in such a manner that a column is erected on the front and rear portions, a lifting pallet is suspended by a lifting chain, and a posture is maintained by a balance chain.
In the column type parking equipment, since the posture of the lifting pallet is always set to be horizontal and the inclination of the lifting pallet cannot be changed, a gutter is provided on the periphery of the lifting pallet as a measure against rainwater.

[0006] Therefore, in such a parking facility, there is a problem that the ease of entry at the entry position is sacrificed, an extra cost is required for providing a gutter, and the appearance is impaired. The present invention solves the above-mentioned problems in parking facilities, and in a four-post parking facility, the inclination of an elevating pallet can be changed between a riding position and a storage position, and a vehicle in a riding position is provided. A pallet tilting device that is easy to get on, prevents rainwater from dripping from the tip of the elevating pallet in the storage position, and does not give a user an uneasy feeling that the vehicle falls. The purpose is to do.

[0007]

SUMMARY OF THE INVENTION A pallet tilting device according to the present invention is an idler before and after a balance chain is wound in a parking facility in which a lifting pallet is suspended by a lifting chain and the posture is maintained by a balance chain. The above-mentioned problem is solved by providing an inclined roller for pressing the balance chain downward when the lifting pallet is raised to the storage position between the sprockets.

When the lifting / lowering chain is driven to raise the lifting / lowering pallet to the storage position, the balance chain is pressed downward between the front and rear idler sprockets by the tilting roller, and the lifting / lowering pallet is tilted forward. When the lifting pallet is lowered to the riding position, the balance chain separates from the tilt roller, and the lifting pallet returns to the reference tilt.

Therefore, if the reference inclination of the lifting pallet is set to slightly forward and downward, the lifting pallet is inclined forward and upward at the storage position, so that dripping of rainwater from the tip of the lifting pallet can be prevented. In this case, the lifting pallet is inclined forward and downward, so that the vehicle can be easily entered.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a side view showing the construction of a parking facility provided with a pallet tilting device according to an embodiment of the present invention. FIG. 2 is a sectional view taken along line AA of FIG. Is B in FIG.
FIG. 4 is a cross-sectional view taken along line B. The parking facility 1 is a traversing up / down type parking facility having a lift pallet 4 on which a vehicle 3 is loaded and a traverse pallet (not shown) at two levels above ground and one level below ground.
The parking facility 1 includes a front support 2 erected on a pit P.
a, a rear pillar 2b and an upper beam 2c, a gate-shaped pillar 2 which is referred to as a four-post parking system because of the structure of the pillar, and the upper and lower lifting pallets 4 are moved from the upper beam 2c to the lifting chain 5 , And can be moved up and down by driving the elevating motor 6.

A traversing rail (not shown) is laid on the middle floor, which is the loading / unloading floor, and a traversing pallet that can move to the left and right is arranged on the traversing rail. At that time, the traversing pallet moves left and right as necessary to secure an empty space. The upper pallet 4 has an idler sprocket 7f in the front and idler sprockets 7m and 7 in the rear.
are provided at predetermined intervals, and a balance chain 8 is hung around idler sprockets 7f, 7m, and 7r,
One end of the balance chain 8 is fixed to the front of the upper beam 2c of the gate-type column 2, and the other end is fixed below the entrance / exit floor of the rear column 2b of the column-type column 2. The balance chain 8 is adjusted such that the reference inclination of the upper pallet 4 is slightly forward and downward.

A roller bracket 13 is provided vertically behind the upper beam 2c of the portal column 2, and a lower end of the roller bracket 13 is provided with the balance chain 8 being lowered when the upper pallet 4 is raised to the storage position. An inclination roller 9 is provided so as to press. The elevating pallet 4 is provided with a passage hole 4a so that the inclination roller 9 can pass therethrough.

On the upper part of the rear support 2b, an upper limit stopper 10 for restricting the elevation of the upper lifting pallet 4 and the front support 2
A lower limit stopper 11 for restricting the lowering of the upper pallet 4 at the upper stage is provided in the vicinity of the entry surface GL of a, and mechanically restricts the vertical range of the upper pallet 4 at the upper stage. The lower pallet 4 is not provided with a pallet tilting device, but the other structure is basically the same as that of the upper pallet 4.

When the vehicle 3 is stored in the upper pallet 4, the upper pallet 4 is lowered to the riding position.
The lifting pallet 4 comes into contact with the lower limit stopper 11 and stops,
The balance chain 8 maintains the reference inclination slightly lowered forward. Therefore, the vehicle 3 can be easily boarded. When the vehicle 3 is loaded, the lifting / lowering motor 6 is driven to wind up the lifting / lowering chain 5, and the lifting pallet 4 in the upper stage is raised. While the ascent / descent pallet 4 is maintained at the standard inclination during the ascent, the balance chain 8 comes into contact with the inclination roller 9 when the pallet 4 reaches the vicinity of the storage position. The lifting pallet 4 is rotated clockwise in FIG. When the lifting pallet 4 is lifted until it comes into contact with the upper limit stopper 10, the lifting pallet 4 stops at a predetermined forward rising inclination.

As described above, in the storage position, the lifting pallet 4
Is inclined upwards, so that rainwater can be
Flows rearward without dripping from the tip, and there is no need to provide a new gutter.
There is no fear of falling from the front of the car.
In this embodiment, the balance chain 8 is adjusted such that the reference inclination of the upper lifting pallet 4 is slightly forward and downward. However, even if the reference inclination is adjusted to be substantially horizontal. Good.

Also, an intermediate idler sprocket 7 m
Is provided to cause a required change in the inclination angle during a short elevating movement, so that the length of the roller bracket 13 can be increased, and the elevating pallet 4 can be tilted during a long elevating movement. It is not always necessary if it is possible to do so. The inclination roller 9 can be moved downward, and the balance chain 8 can be pressed downward when the upper pallet 4 is raised to the storage position.
