Description

[Detailed description of the invention] a Industrial application field The present invention relates to an improvement in a two-stage parking device.

b. Conventional technologies and their problems Various types of two-stage parking devices have been proposed in the past, each exhibiting its own advantages.

In other words, some conventional two-tier parking systems use a system in which the upper pallet is suspended from a chain or rope to be raised and lowered, but this system requires a pillar to support the suspension system on the entrance and exit side of the car. , the width of the doorway was limited by the hanging chain or rope.

In addition, among conventional parking devices, the lower pallet can be moved laterally, and a drive device is attached to each of the lower pallets, so when lowering the upper pallet, multiple drive devices are used to move the lower pallet. I had to move it laterally.

The present invention has been devised to effectively solve the above-mentioned problems, and its purpose is to make it easier for cars to enter and exit than the conventional two-stage parking system when a plurality of parking systems are installed in parallel. To provide a parking device that is comfortable and easy to operate.

c. Means for Solving the Problems In order to solve the above-mentioned problems, the present invention includes an upper pallet that can be raised and lowered and a lower pallet that can be moved laterally, and the upper pallet can be moved from the parking position of the automobile. It is supported so as to remain horizontal at all times by the tips of two parallel rods on each side, which are rotatably pivoted to a pillar installed on the back side.A support frame and a hydraulic An elevating drive device consisting of a cylinder is installed, and a plurality of lower pallets are arranged on a track installed in a direction transverse to the direction of vehicle entry and exit, and an Abt type rail is provided parallel to the above track, and each adjacent pallet is The lower pallets are connected to each other by a removable coupler, and the lower pallet at the end is equipped with a traverse drive device consisting of a gear that meshes with the Abt type rail and an electric motor that drives the gear. .

d. Effect In the parking device of the present invention configured as described above, there are no pillars on the entrance/exit side of cars, and there are no chains or ropes for suspending pallets, so the space between cars parked next to each other can be used effectively. In addition to making it easier to drive in and out of cars, the path for users is also wider, and multiple lower pallets can be moved laterally at the same time with a single traverse drive device, making it easier to operate the parking device than before. It is simpler than the previous model, and because the lower pallet is equipped with a gear that meshes with the Abt type rail, it does not slip even when it rains or snows, so it can be used outdoors in all weathers.

e Example An example of the present invention will be described below based on the drawings.

In Figures 1 and 2, 1 is the lower palette, 2
is the upper palette. Lower pallet 1 is track 3
It can be moved laterally using wheels 4 on the top. The upper pallet 2 is provided with a support plate 5 at its rear, to which the tips 6 ₁ and 7 ₁ of parallel rods 6 and 7 are pivotally connected, and whose base ends 6 ₂ and 7 ₂ are attached to fixed columns 8.

On the other hand, a lever 14 is fixed to the front end of the parallel rod 6, and the lever 14 is connected to the continuous rods 15, 16, 17.
It is connected to the support rod 13 via. 18 is a lever attached to the support rod 13, and 19 is a footboard.

Now, in the state shown in FIG. 1, operate the switch on the switch box 12 to change the
When the hydraulic cylinder 11 is lowered via a hydraulic circuit (not shown) after being moved toward the front toward the plane of the paper, the parallel rods 6 and 7 are retracted using the base ends 6 ₂ and 7 ₂ as fulcrums. It rotates clockwise and the upper pallet lowers to the position of the lower pallet.

At this time, the lever 14 is rotated by a certain angle, and the support rod 13 is thereby rotated clockwise via the connecting rods 15, 16, 17 and the lever 18. The switchbox 12 is thus maintained at or near its old position.

In FIG. 3, reference numeral 20 denotes a wheel stopper piece, which has a shaft 22 in a hole 21 provided in the front part of the upper pallet 2.
23 is a roller provided at the lower end, 24 is a spring, and 25 is a stopper.

Now, as mentioned above, when the upper pallet 2 is lowered to the lower position, the roller 23 hits the stopper 25, causing the wheel stopper piece 20 to rotate clockwise and disappear from the upper surface of the pallet into the pallet surface. (See Figure 3).

In FIG. 2, when the switch in the switch box 12 is operated, the cylinder 11 is extended and the upper pallet 2 is returned to its original position as shown in FIG. At the same time, the wheel stopper piece 20 is rotated counterclockwise by the spring 24 and protrudes above the upper pallet surface.

FIGS. 4 and 5 show six parking devices arranged in a horizontal direction. In each of these figures, the same parts as in FIGS. 1 and 2 are designated by the same reference numerals.

In each of the above figures, the lower pallet 1 is the coupler 2.
As shown in FIG. 6, the coupler has a hook-shaped piece 27 attached to the right end of the lower pallet 1, and a hook-shaped piece 28 pivotally attached to the left end of the lower pallet. , a roller 2 provided at the rear end of the piece

The above is the order of parking work for the upper pallet, but for the lower pallet, it is sufficient to drive the car into each vacant lower pallet.

f Effects of the Invention In the parking device of the present invention, each parking device is detachably connected, and the combination of the number of installations can be freely changed.
Parking devices can be arranged rationally.
Furthermore, with the parking device of the present invention, there are no pillars on the entrance/exit side of cars, and there are no chains or ropes for suspending pallets, so the space between cars parked next to each other can be used effectively, and the entrance/exit of cars can be effectively utilized. In addition to making driving easier, the aisles for users are also wider.
In addition, multiple lower pallets can be moved laterally at the same time with one traverse drive device, making the operation of the parking device easier than with conventional parking devices.In addition, the lower pallets are equipped with gears that mesh with Abt type rails. Once installed, it will not slip even when it rains or snows, so it can be used outdoors in all weather conditions.

In addition, in conventional parking devices, the switch box is fixed to a pillar or wall, and when operating multiple parking devices, the switch of each parking device is built into a central operation panel, and the switch number of each parking device is connected to the corresponding parking device. Many switches are designed to be operated by a central control panel, but this requires walking to the central control panel each time, and if there are many switches in a row, there is a greater risk of accidentally operating the switch by mistake.

However, since a switch box is attached to each upper pallet of the parking device of the present invention, there is less risk of turning on the wrong switch, and since it can be operated on the spot, waiting time is shortened and emergencies can be dealt with immediately.

In addition, a fan-shaped wheel stopper is attached to the front of the upper pallet, which protrudes when the pallet is raised to prevent the car from falling, but when the pallet is lowered, it is automatically retracted into the inner surface of the pallet and becomes flat, preventing the car from falling. The vehicle can be moved in and out without any resistance, and since the wheel stopper piece is fan-shaped, no undue force is generated between the wheel and the wheel stopper.
