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 which can store two cars 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 parking position with one end located at the bottom of the bit as a center of rotation, and a loading / unloading position where the other end tilts upward, and a predetermined space above the lower pallet. The upper pallet, which is horizontally disposed, has the other end inclined 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 portion. Side of the upper pallet is rocked up and down to swing the lower pallet up and down, and the other end of the upper pallet is hoisted and the other end is rocked up and down. A parking device including a drive device that swings the entire upper pallet up and down to switch between a parking position and a loading / unloading position is disclosed. 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 parking position and a position where the tip is tilted downwards and retracted, a parking position that is arranged above the lower pallet, and the rear part is tilted 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 conventional parking devices described above, the former one, which is disclosed in Japanese Utility Model Laid-Open No. 63-51053, allows the lower car to be stored in the bit.
While it has the advantage that the height from the reference plane can be reduced, it requires separate drive devices to swing the upper and lower pallets up and down. On the other hand, the latter Japanese Patent Laid-Open No. 5-44
The device shown in No. 353 has the advantage that the upper and lower pallets are interlocked to swing up and down, and the same actuating device is used for the drive source, but two cars are stored above and below the reference plane. Therefore, the height from the reference surface becomes higher, and the upper and lower pallets are always linked, and power is always required to raise and lower two cars when switching.

A first object of the present invention is a two-stage structure in which the height from the reference plane can be reduced, the upper and lower pallets can be operated using a common drive source, and the power required for switching can be reduced. It is intended to provide a tilting parking device. A second object of the present invention is to provide a two-step tilt type parking device capable of lowering a height from a reference plane as compared with a conventional device.

[0005]

The parking device for achieving the first object can be switched between a horizontal parking position with a rear end located at the bottom of the pit as a center of rotation and an warehousing position inclined upward. The lower pallet and the upper pallet, and is tilted up and down with the rear end as the center of rotation.
The upper pallet that can be switched between a loading / unloading position where the whole is tilted downward and the tip side is further tilted downward from the hinge engaging part in the middle part, and a horizontal parking position, and the tip side of the upper pallet is lifted and lowered. Hanging position, and sheaves, pulleys, sprockets, etc. (hereinafter simply referred to as sheaves) that are pivotally supported on the tip side of the upper pallet, hung on the sheaves, etc., one end is connected to the lower pallet, and the other end is weighted. It is characterized in that it is constituted by a wire such as a wire, a rope, a chain, and the like connected to each other, and a stopper that engages with the weight and restricts the lifting of the weight by a certain amount or more.

According to this device, the car on the lower pallet is stored in the bit at the parking position. Further, when the upper and lower pallets are horizontal and are in the parking position with respect to each other, depending on the hoisting position, the entire upper pallet is lowered with the rear end as the center of rotation, and the tip end side is lowered from the hinge engaging portion to switch to the loading / unloading position. Also, the entire pallet and the tip side can be lifted to switch to a horizontal parking position. Therefore, with the lower pallet in the parking position,
Only the upper pallet can be switched to the parking position or the loading / unloading position. The weight goes up and down as the upper pallet is switched. That is, if the tip side of the upper pallet is lowered and the gap with the lower pallet is narrowed, at least the weight is lowered accordingly, the tip side of the pallet on the upper stage is lifted from the loading / unloading position, and the gap with the lower pallet is widened. , And the weight increases accordingly.

As described above, when raising and lowering the upper pallet, the weight also rises and falls. Therefore, when switching the upper pallet between the horizontal position and the loading / unloading position, the power required to raise and lower the pallet on which the vehicle is mounted, the power required to raise and lower the weight, and the frictional resistance between the sheave and the rope. However, if the weight is made light enough to absorb the slack in the rope, the power of the latter two will be reduced and the pallet on which the car is placed will be raised and lowered. It will be enough to power.

When the lower pallet is switched to the loading / unloading position, the entire upper pallet is lifted upward by the lifting position. Then, the lower pallet is lifted by the upper pallet with the weight locked to the stopper. A parking device for achieving the second object is a horizontal parking position with a rear end located at the bottom of the pit as a rotation center.
The lower pallet that can be switched to the loading / unloading position that tilts upward, and the lower pallet that is disposed above the lower pallet, tilts up and down with the rear end as the center of rotation, and tilts downward as a whole, and It has an warehousing position where the front end side inclines further downward from the hinge engaging portion, an upper pallet that can be switched to a horizontal parking position, and an operating device that raises and lowers the upper and lower pallets. The center of rotation is located closer to the tip side than the center of rotation of the rear end of the upper pallet.

In FIG. 1, the upper and lower pallets 1 and 2 are tilted upward to switch the lower pallet 1 to the loading / unloading position, and the height from the reference plane V to the vehicle 3 stored in the upper pallet 2 is maximum. As shown in the figure, a space L is secured between the pallets 1 and 2 so as not to interfere with the entry and exit of the vehicle stored in the lower pallet 1. When the rotation center of the lower pallet 1 is displaced from o to o ′, the rotation center of the upper pallet 2 is lowered by ΔL, and the height H of the vehicle 3 is also lowered by ΔH from the reference plane V.

In each of the above parking devices, it is desirable that the upper pallets are connected at a plurality of places by hinges that can rotate at a constant angle. As a result, the upper pallet can be gradually refracted at a plurality of locations along the car stored in the lower pallet, and the refraction angle can be reduced, so that the car is not supported at the refraction site. The upper pallet is also preferably provided with a stopper at the center of rotation so that the stopper does not tilt downward by more than a certain amount by hitting the frame.

The upper and lower pallets in each of the above parking devices may also have their front ends aligned with the reference plane at the loading / unloading position, but in order to enable smooth loading and unloading without any steps from the reference plane, For each pallet,
Preferably, a tipping plate is provided at the tip thereof.
When the transfer board is provided, the lifting and lowering of the transfer board may be performed manually, but preferably, it is desirable to automatically perform the operation in conjunction with the lifting and lowering of the pallet. For this purpose, for example, a transfer plate is attached to a bracket that is pivotally supported on the tip of the pallet and is urged in one rotation direction by a spring. It is advisable to engage with the engaging groove of the above so as to be detachable. That is, when the pallet is lowered, after the rollers are fitted in the engaging grooves, and the pallet is still lowered, the bracket turns against the action of the spring and the bridge plate is tilted, and the pallet rises and the roller When is disengaged from the engaging groove, the bracket is pivoted in the direction opposite to the above by the action of the spring to raise the bridge plate.

By fitting the roller in the engaging groove, the movement of the roller is restrained, and the pallet can be held at the loading / unloading position.
