Abstract

PURPOSE:To prevent a pallet from jumping, to prevent an impact noise and creak from occurring, and to prevent the pallet from breaking, in the title device. CONSTITUTION:A slope plate 20 is rotatably extended at the end part of a pallet 19 for placing a vehicle, at which end side the vehicle is driven onto the pallet or from thereon and which pallet is provided so as to be movable to each story in a multistory parking space 1. Either on the side of the slope plate 20 or on the side of the pallet 19, a stopper 24 is provided, by which the slope plate 20 stops at the position where the slope plate 20 at a horizontal position rotates downward by a fixed angle. For that reason, before the pallet 19 reaches a floor 13 by lowering, the downward rotation of the slope plate 20 is restricted by the stopper 24 and the slope plate 20 is held in the condition that the top end part thereof slightly rotates downward, and thus the top end part of the slope plate 20 abuts the floor 13 at all times when the pallet 19 is lowered. In this way, the top end part of the slope plate 13 can be prevented from lifting.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention provides a pallet for mounting a vehicle, which is mounted on each floor of a multi-story multi-story car park so that it can be moved up and down or traverses easily at the vehicle entrance and exit when the vehicle enters and exits. The present invention relates to a device for entering and exiting a pallet of a multi-tiered multi-storey parking lot.

[0002]

2. Description of the Related Art Recently, in order to effectively utilize a parking lot, parking lots are becoming three-dimensional. For example, many multi-tiered multi-storey parking lots are constructed in which a vehicle is placed on a pallet and a plurality of the pallets are stacked and arranged. 3 and 4 show an example of the multi-level multi-storey parking lot 1, and the parking lot shown in this figure is a four-tiered parking lot.

On the first floor of the building 2 of the multi-storey car park 1, there are arranged pallets 4 on which vehicles 3 are placed. Also,
A plurality of horizontal frames 5 are attached to a portion corresponding to the second floor to the fourth floor, that is, a portion corresponding to the second floor to the fourth floor. A part of this frame 5 is a width for raising and lowering the vehicle 3,
The pallets 4 are mounted at intervals, and the pallets 4 are suspended from the frames 5 of the respective stages via wires 6 so that the pallets 4 can be moved up and down.

As shown in FIG. 5, the pallet 4 is lifted and lowered.
The other end of the wire 6 having one end attached to each of the front left and right sides and the rear left and right sides of the pallet 4 is connected to a drum (not shown) connected to a rotating shaft of a lifting motor 7 provided in each stage frame 5, This is done by operating the lifting motor 7. The lifting motor 7 is disposed between the left and right frames 5 as shown in FIG.

Further, each frame 5 on which the pallet 4 is suspended
A traverse motor 8 is provided in the inside of the machine to drive a traverse roller 9 described later (see FIGS. 6 and 7). The traverse rollers 9 are provided at the front end and the rear end of the frame 5 located on the left and right of the vehicle 3, and roll on the traverse rails 10 arranged in the horizontal direction.

The traverse rail 10 is supported by a bracket 12 fixed to a pillar 11 of the building 2 as shown in FIG. In the case of the parking lot 1 shown in FIGS. 3 and 4, the traverse rails 10 are provided in the second and third stages. Therefore, the frame 5 of this parking lot 1 has the second and third stages,
The bottom and top tiers do not traverse.

FIG. 5 shows a state in which the pallet 4 located between the third-stage frames 5 is lowered to the lowermost position, and the vehicle 3 is placed in the pallet 4. Then, after the pallet 4 has been lifted as shown in FIG.
And the traverse roller 9 is adapted to traverse.

When the pallet 4 is lowered to the entry / exit point of the vehicle 3 as described above, the bottom of the pallet 4 arrives at the floor 13 so that a step is not generated between the floor 13 and the pallet 4. A pit 14 is provided so that the heights of the pallet 4 and the floor 13 coincide with each other.

However, as shown in FIG. 5, when the pit 14 is not provided, a step is formed. Therefore, a slope plate 15 as shown in FIGS. 5 to 8 is fixedly provided on the vehicle entrance / exit side of the pallet 4. . If the slope plate 15 is provided on the pallet 4 in this manner, there is no step, and the vehicle 3 can be smoothly moved in and out of the pallet 4.

In FIG. 5, reference numeral 16 is a sheave, reference numeral 17 in FIG. 6 is a wire suspension portion provided on the pallet 4, and reference numeral 18 is a reference numeral 18 in FIGS. Is cushion rubber

[0011]

In the conventional technique described above, since the slope plate provided to eliminate the step between the pallet and the floor is fixed to the pallet,
When the pallet is lowered and the pallet is landed at a level where vehicles can move in and out, the tip of the slope plate may rise as shown in Fig. 8 due to the manufacturing precision of the pallet and unevenness of the floor surface of the building. there were. In such a state, when the vehicle is moved in and out of the pallet, when one wheel of the vehicle is placed on the slope plate, the rear end of the pallet is splashed by the weight of the vehicle, and impact noise or squeak noise is generated. Also, there was a problem of damaging the pallet.

The present invention has been made in order to solve the above-mentioned conventional problems, and by improving the mounting of the slope plate on the pallet, the difference between the upper and lower levels of the slope plate and the floor is corrected and the impact is improved. An object of the present invention is to provide a device for entering and exiting a pallet of a multi-level multi-storey parking lot, which suppresses the generation of noises and squeaks and eliminates damage to the pallet.

[0013]

As a means for solving the above-mentioned problems, the present invention provides an end portion on the vehicle entrance / exit side of a pallet for loading a vehicle, which is movably provided on each layer of a multi-story multi-story parking lot. A slope plate is rotatably extended on the base plate, and a stopper is provided on either the slope plate or the pallet to stop at a position where the slope plate rotates downward from a horizontal position by a predetermined angle. It is what

[0014]

Since the present invention has such a structure, the downward rotation of the slope plate is restricted by the stopper before the pallet descends and the floor is landed, and the tip of the slope plate is downward. It is held in a slightly rotated state. When the pallet lands on the floor, the tip of the slope plate, which is slightly rotated downward, lands first, so if the pallet is further lowered in the landed state, the slope plate will rotate. In the moving state, the tip of the slope plate is always in contact with the floor. This makes it possible to prevent the slope plate from rising up.

When the vehicle is moved in and out of the pallet in the state where the tip of the slope plate is in contact with the floor in this way, the pallet does not descend even if one wheel of the vehicle is placed on the slope plate, so the pallet jumps up. Can be prevented.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG. 1 with the same members as those in FIGS. In the figure, reference numeral 19 indicates a pallet attached to a multi-level multi-storey parking lot, and reference numeral 20 indicates this pallet.
19 shows a slope plate attached to 19.

The slope plate 20 has a mounting arm 22 provided at the base of the slope plate 20 rotatably attached to a bracket 21 provided on the bottom surface of the pallet 19 on the vehicle entry / exit side by a pin 23. This slope plate 20 is installed on the entrance side of the pallet 19 and the floor 13
Mounted between and.

A stopper 24 for holding the slope plate 20 with respect to the bracket 21 in a state of being slightly rotated downward with respect to the mounting arm 22 of the slope plate 20 is provided so as to project toward the abutting portion 25 of the bracket 21. Has been done. In this way, the slope plate 20 is slightly rotated downward when the pallet 19 is lowered, and the tip end 20a of the slope plate 20 is landed before the cushion rubber 18 provided on the bottom surface of the pallet 19 is landed. 20 tip 20
a, even when pallet 19 descends to the bottom,
This is to ensure that they are in the floor. (The slope plate 20 shown by the broken line in FIG. 1 is the one when the pallet 19 is lowered to the lowermost part after the tip 20a of the slope plate 20 has landed). Therefore, when the pallet 19 is not on the floor, at least the stopper 24 is in contact with the contact portion 25 of the bracket 21.

The wire 6 shown in FIG. 1 is attached to the front, rear, left and right of the pallet 19 and to the rear left and right.
Is connected to the drum of the lifting motor 7 provided on the frame 5 of the building 2 of the multi-storey car park 1 (see FIGS. 5 and 6).

In the pallet loading / unloading device configured as described above, the downward rotation of the slope plate 20 is restricted by the stopper 24 before the pallet 19 is landed on the floor. The slope plate 20 is held in a state of being slightly rotated downward.

When the pallet 19 is landed, the tip 20a of the slope plate 20 which is slightly rotated downward is landed before the cushion rubber 18 of the pallet 19. In this way, with the tip 20a of the slope plate 20 landed, if the pallet 19 is further lowered to land, the tip 20a of the slope plate 20 is always rotated by simply rotating the slope plate 20. It is in contact with the floor 13 (see FIG. 2). Therefore, the tip portion 20a of the slope plate 20 does not float above the floor 13. At this time, the stopper 24 and the contact portion 25
A gap L corresponding to the rotation distance will be generated between and.

In this way, with the tip 20a of the slope plate 20 in contact with the floor of the entrance and exit of the vehicle 3, the pallet 19
When the vehicle 3 moves in and out of the slope plate 20, the slope plate 20 does not lower even if one wheel of the vehicle 3 is placed on the slope plate 20.
Since the load will be received on all edges of the tip 20a of 20,
The generation of impact noise and squeak noise is prevented, and damage to the pallet 19 is prevented.

Although the stopper 24 for holding the downward rotation of the slope plate 20 is attached to the mounting arm 22 of the slope plate 20, the present invention is not limited to this, and the stopper 24 is not limited to the bracket of the pallet 19.
May be mounted on 21. The operation in this case is the same as that described above, and will be omitted.

The stopper 24 may be mounted by screwing it into a screw hole at a mounting point, and the amount of screwing in may change the amount of protrusion of the stopper 24 to adjust the rotation angle range of the slope plate 20.

[0025]

Since the present invention is constructed as described above, when the pallet is landed, the slope plate is held in a state of being slightly rotated downward, and when the pallet plate is landed. In this case, the slope plate that is slightly rotated downward will land first. As a result, when the pallet is moved to the bottom, the tip of the slope plate is surely grounded on the floor and its lifting is avoided. In this state, even if one wheel of the vehicle is placed on this slope plate, the slope is in a stable state, and the load is applied to all the edges of the slope plate,
The pallet will not be distorted. Therefore, no impact noise or squeak noise is generated on the pallet, and the vehicle can be silently moved in and out. In addition, damage to the pallet can be prevented.
