Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a two-step tilt type parking apparatus capable of storing a vehicle in two upper and lower stages.

[0002]

2. Description of the Related Art As a parking device of this type, the actual construction of Sho 63-51
No. 053 has a lower pallet that can be switched between a horizontal storage position with one end located at the bottom of the bit as a center of rotation and a loading / unloading position in which the other end is inclined upward, and a predetermined interval above the lower pallet. The upper pallet, which is located in the storage position and has the other end tilted upward, and the other end of the lower pallet that is horizontal and can be switched to the loading / unloading position by folding the other end side downward from the hinge engaging part. Side of the upper pallet to swing up and down to swing the lower pallet up and down to switch between the storage position and the loading / unloading position, and to lift the other end of the upper pallet to swing the other end up and down. A parking device including a drive device that swings the entire upper pallet up and down to move back and forth to switch between a storage position and a loading / unloading position is disclosed, and JP-A-5-44353 discloses a rear end located on a reference plane. Horizontally centered around A lower pallet that can be switched between a storage and storage position and a position where the tip is inclined downwards and retracted, a storage position that is arranged above the lower pallet, and the rear part is inclined downwards, and the front part is lower than the horizontal rear part. A parking device is disclosed that includes an upper pallet that can be switched to an inward / outgoing position that is inclined, and an operating device that switches the two positions by swinging the upper and lower pallets up and down in conjunction with each other.

[0003]

Among the above-mentioned conventional parking devices, the latter device disclosed in Japanese Patent Laid-Open No. 5-44353 has a vehicle stored above and below the reference plane, and therefore the height from the reference plane is high. As the car moves in and out of the upper pallet to the reference surface, the inclination angle of the upper pallet increases.

On the other hand, the former method, Shokai 63-5105.
In the device shown in No. 3, since the lower car is stored in the bit, the height from the reference plane is low, and therefore the inclination angle of the upper pallet when the car goes in and out of the upper pallet is small. However, the deeper the bit, the greater the inclination angle of the lower pallet when the vehicle moves in and out of the reference plane.

According to the present invention, the lower car can be housed in the bit so that the height from the reference plane can be lowered and the inclination angles of the upper and lower pallets when the car comes in and out can be reduced. An object is to provide a tilting parking device.

[0006]

Therefore, the parking device of the present invention has a storage position in which one end of the bit reaches the reference plane and inclines upward, and a storage position in which one end descends from the reference plane and is located at the bottom of the bit. A lower pallet that can be switched, and a loading / unloading position that is arranged above the lower pallet and has one end reaching the reference plane and inclining downward, and there is no obstacle for vehicles to move in and out of the lower pallet at the loading / unloading position. In a two-tiered tilting parking device having an upper pallet that can be switched to a storage position in which one end is lifted from the reference surface to a position, and an operating device that switches the upper and lower pallets to a loading / unloading position and a storage position. The end is characterized in that it is pulled up when the lower pallet is switched to the loading / unloading position and descends to the bottom of the bit when switched to the storage position.

According to this apparatus, since the other end of the lower pallet is pulled up at the loading / unloading position, the inclination angle becomes small. One end and the other end of the lower pallet may be individually lifted and lowered by separate actuators, but the same pallet may also be used for lifting and lowering. FIG. 1 shows an example thereof. One end A of the lower pallet 2 can be moved up and down along a guide 3 in the bit 1, and the other end B is connected to a rotation center o by an arm 4 to form a slider crank. When the one end A is pulled up by the actuating device in the arrow direction, the other end B also rises along an arc locus in the arrow direction. The alternate long and short dash line indicates the entry / exit position. Instead of connecting the other end B with the arm 4, a guide having a shape along an arc locus may be provided and the other end B may be reciprocated along the guide.

FIG. 2 shows another example of the wire 5
Is hung on a sheave 6 provided at one end A of the lower pallet 2 and connected to the other end B of the pallet via guide sheaves c ₁ and c _{2 so} that one end A of the lower pallet 2 does not move above the reference plane b. Is provided with a stopper (not shown).
In the case of this example, when the wire 5 is pulled up in the direction of the arrow, one end A of the lower pallet 2 is pulled up, and the stopper is used to prevent the rise of the wire 5.
Is lifted, the other end B of the lower pallet 2 is lifted. In this example, the lower pallet 2 is supported at both ends by the wire 5 and the supporting load is dispersed, so that the pulling force when pulling up the one end A is small,
The lower pallet 2 can be pulled up smoothly.
In order to make the movement of the lower pallet 2 smoother and more reliable, as shown in FIG. 1, one end A of the lower pallet 2 can be moved up and down along a guide, and the other end B of the lower pallet 2 is rotated around the rotation center o and the arm. It is better to connect by. In this case, the stopper can be omitted.

At least one of the sheaves c ₁ and c ₂ is position-adjustable or a turnbuckle is provided on the wire so as to absorb elongation. Wires can also be replaced by ropes, chains or other cords. When using a chain, a sprocket is used instead of the sheave. In a preferred apparatus, one end of the lower pallet is brought closer to the reference surface as it is pulled up to the reference surface. If there is a gap between one end of the pallet and the reference surface, bridge it,
It is necessary to make sure that it does not interfere with the entry and exit of cars,
This is because if one end of the pallet approaches the reference plane and there is no gap or the gap becomes small, it is not necessary to bridge. Similarly, when the upper pallet does not need to be bridged, the tip end of the upper pallet is connected to the reference plane without a gap when it is switched to the loading / unloading position.

In order to make one end of the lower pallet approach the reference surface as it is pulled up to the reference surface, for example, the guide may be formed so as to approach the reference surface as one end of the pallet reaches the reference surface. By providing the guide, it is possible to provide the following safety device.

This safety device is provided at one end of a pallet, and a runner that moves up and down along a guide, and a pawl lever that is axially attached to the runner and always presses the guide with a spring to fix the runner. It is connected and consists of a wire such as a wire or chain that pulls up the claw lever against the action of the spring, and when the wire is cut and the tension is released,
The claw lever rotates by the action of the spring and is crimped and fixed to the guide to fix one end of the pallet. Therefore, if this safety device is used, the risk of the pallet falling even if the cord is cut can be eliminated.

The upper pallet and the lower pallet may be switched between the loading and unloading position and the storage position by separate actuating devices, but it is preferable that the applicant of the present invention file the Japanese Patent Application No. 6-9 first.
It is possible to switch using a common actuating device, as proposed in No. 9577. FIG. 3 shows an example thereof, in which the upper pallet 8 is supported so as to be tiltable up and down about a fulcrum D, and a loading and unloading position indicated by a solid line in a winding device (not shown) that constitutes an operating device and one point. It can be switched to the storage position shown by the chain line. As shown in FIG. 1, one end A of the lower pallet 2 is supported by a guide (not shown) so as to be able to move up and down, and the other end B is a rotation center o.
Are connected by an arm 4. And one end A
The wire 5 connected to the upper pallet 8 is connected to the other end of the lower pallet 2 via the sheave 6 at one end A of the lower pallet and the guide sheaves c ₁ and c ₂ .

According to this apparatus, when the upper pallet 8 is pulled up from the solid line position to the alternate long and short dash line position by the winding device, the wire 5 connected to one end A of the upper stage pallet 8 causes the lower pallet 2 to move from the solid line position to the alternate long and short dash line as described above. It is pulled up to the position.
