Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a two-stage parking device.

[Prior Art] FIG. 2 shows an example of a two-stage parking apparatus. A pit 1 having a parking space is provided in the basement, and lower tiers are vertically movable along guides 2 provided on both side surfaces of the pit 1. The pallet 3 is arranged in the pit 1, columns 4 are erected on both sides of the rear part of the lower pallet 3, and the upper pallet 5 is supported by the upper ends of the columns 4 in an overhang shape. At this time, the upper pallet 5
In consideration of the fact that the front end portion 7 side of the upper pallet 5 is bent so as to sink due to the load of the loading / unloading vehicle 6, the front end portion 7 side is slightly raised in advance and held in the forward ascending state, When the loading / unloading vehicle 6 is loaded, the loading / unloading vehicle 6 is configured to be just horizontal due to its weight.

Further, a driving device 9 for raising and lowering the lower pallet 3 while suspending and supporting the lower pallet 3 in a horizontal state via a chain 8 is provided at the rear portion of the pit 1.

When neither the lower pallet 3 nor the upper pallet 5 is parked, the lower pallet 3 is in a raised position so as to coincide with the ground surface. When entering from this state,
The first loading / unloading vehicle 6 rides on the lower pallet 3, and then the lower pallet 3 is lowered by the drive device 9 and stored in the pit 1. In this state, the second loading / unloading vehicle 6 for the upper pallet 5 is loaded. When the lower pallet 3 is unloaded, the lower pallet 3 is raised to the ground surface and then unloaded. By the above, two cars can be accommodated in the upper and lower pallets 3, 5 in the space for one car.

[Problems to be Solved by the Invention] In the two-stage parking apparatus as described above, the upper pallet 5
When using, even if the lower pallet 3 is lowered into the pit 1 and the upper pallet 5 is lowered to the ground surface, the upper pallet 5 is supported in a state in which the front end portion 7 side is slightly raised. In the empty state, there is a problem that the load is insufficient and a step S is generated between the ground surface and the front end portion 7, which hinders smooth entry.

The present invention solves the above problem. Even when the upper pallet 5 is empty, when the lower pallet 5 is lowered and used, the ground surface and the front end portion 7 of the upper pallet 5 become horizontal. It is an object to provide a stepped parking device.

[Means for Solving the Problem] In the present invention, a lower pallet is supported in a pit provided in the basement so that the lower pallet can be moved up and down. In a two-tiered parking apparatus equipped with an upper pallet supported so as to be slightly higher, a hooking portion is provided at the front end of the upper pallet so that the lower pallet hangs on the upper end of the pit front when the lower pallet is lowered to the pit bottom. Between the lower surface of the rear part of the lower pallet and the position of the bottom of the pit between the lower pallet and the lower pallet for tilting and supporting the lower pallet so as to keep the upper pallet in a horizontal state when the lower pallet is lowered. The present invention relates to a two-stage parking device, which is provided with a tilt receiving member.

[Operation] When the lower pallet is lowered into the pit in order to store it on the upper pallet, first, the lower pallet forward tilt receiving member provided between the lower end lower surface of the lower pallet and the bottom surface of the pit comes into contact. The rear end of the lower pallet is supported away from the pit bottom surface, while the front end of the lower pallet descends until it abuts the pit bottom, whereby the lower pallet is tilted forward. As a result, the hanging portion extending to the front end of the upper pallet just hooks on the upper end of the front part of the pit, so that there is no step between the upper pallet and the ground surface, and the upper pallet, which has been in the front ascending state, becomes horizontal.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows an embodiment of the present invention, in which the same reference numerals as in FIG. 2 represent the same parts.

As shown in the figure, a pit 1 having a parking space is provided underground, and lower pallets 3 which can be raised and lowered along guides 2 provided on both side surfaces of the pit 1 are arranged in the pit 1, and both rear sides of the lower pallet 3 are arranged. Further, a column 4 having a length substantially equal to the depth of the pit 1 above the vehicle height of the loading / unloading vehicle 6 is erected, and an upper pallet 5 is supported above the column 4 in an overhang shape. At this time, in consideration of the sinking of the front end portion 7 of the upper pallet 5 due to the load of the loading / unloading vehicle 6, the upper pallet 5 is preliminarily held in a state in which the front end portion 7 side is slightly raised in advance, The loading / unloading vehicle 6 is supported so as to be horizontal when loaded.

A hook portion 11 is extended from the front end portion 7 of the upper pallet 5. At this time, when the lower pallet 3 is lowered to the bottom surface of the pit, the hanging portion 11 of the upper pallet 3 of the empty vehicle is just hooked on the upper end of the front portion of the pit 1 as shown in FIG. The mutual spacing (height) of the front ends of the pallets 5 is set.

Further, when the lower pallet 3 is lowered on the lower surface of the rear end of the lower pallet 3, the lower pallet 3 is supported by tilting the lower pallet 3 forward so as to hold the upper pallet 5 in a horizontal state. To provide. The angle at which the lower pallet 3 is tilted forward when the lower pallet 3 is lowered by the lower pallet forward tilt receiving member 10 is substantially equal to the tilt angle at which the upper pallet 5 is moved forward when the vehicle is empty.

Further, a driving device 9 for raising and lowering the lower pallet 3 while suspending and supporting the lower pallet 3 in a horizontal state via a chain 8 is provided at the rear portion of the pit 1.

The operation will be described below.

When the lower pallet 3 is lowered into the pit 1 in order to store it on the upper pallet 5, first, the lower pallet forward tilting receiving member provided between the rear end lower surface of the lower pallet 3 and the bottom surface of the pit 1 comes into contact. Thus, the rear end of the lower pallet 3 is supported in a state of being separated from the bottom surface of the pit 1, while the front end of the lower pallet 3 is lowered until it comes into contact with the bottom of the pit 1, whereby the lower pallet 3 is tilted forward. This time,
The hook 11 extending to the front end of the upper pallet 5 is exactly the pit 1.
By hanging on the upper end of the front part, there is no step between the upper pallet 5 and the ground surface, and the upper pallet 5 which has been in the front rise is brought into a horizontal state.

Therefore, according to the above, in consideration of the load of the loading and unloading vehicle 6, the upper pallet 5 front end portion 7 side is slightly raised and the inclined portion configured in the forward ascending state is received by the lower pallet forward lean receiving member 10. Since the lower pallet 3 is compensated by tilting it forward, even if the upper pallet 5 is empty, there is no step between the ground surface and the front end 7 when the upper pallet 5 is lowered to the ground surface, and the upper pallet 5 is It will be in a horizontal state and can be stored smoothly.

The two-stage parking apparatus of the present invention is not limited to the above-described embodiment, but a lower pallet forward tilting receiving member may be provided on the bottom side of the pit. It goes without saying that various changes can be made within the range not covered.

[Effects of the Invention] As described above, according to the two-stage parking apparatus of the present invention, even when the upper pallet is empty, it is extended to the front end of the upper pallet when the upper pallet is lowered and used. Since the hanging part hooks on the upper end of the front part of the pit, there is no step between it and the ground surface, and the lower pallet forward tilt receiving member is sandwiched between the lower bottom part of the lower pallet rear part and the pit bottom surface, and the lower pallet tilts forward. By doing so, the upper pallet is held in a horizontal state, so that the ground surface and the upper pallet surface are in a horizontal state with no step, and there is an excellent effect that smooth warehousing can be performed.
