Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a pallet parking device used in a mechanical parking system, and more particularly to a movable parking device provided with a safety fence.

[Prior Art] A mechanical parking device has been put into practical use in which a car is mounted on a rectangular pallet, and the car is moved horizontally along with the pallet and stored in a parking area. The pallets used in this mechanical parking system are generally equipped with a car stopper and a car stopper to prevent the car from running away when the car drives onto the pallet or when the pallet is moved. A safety fence is provided to prevent vehicle doors from opening when loading and transporting pallets.

However, as shown in Figs. 10 and 11, a pallet with a conventional vehicle IL device is constructed by fixing a plurality of protrusions 2 on a pallet 1, inserting a wheel between them, and controlling the forward and backward movement of the wheel. It was a fixed type that regulated the following:

Furthermore, as shown in, for example, Japanese Unexamined Patent Publication No. 50-21467, the safety fence is selectively raised and lowered on the side surface of the pallet by a drive device that independently raises and lowers only the safety fence.

[Problems to be Solved by the Invention] Conventional car stop devices are of a fixed type, so when a car is loaded onto a pallet or taken out from a pallet, each time a wheel crosses over the car stop device, the car stops. It shakes up and down significantly, causing discomfort to passengers.

In addition, it was difficult to operate the accelerator when driving over a car stop, and there were cases where the accelerator was too weak and the engine stalled, or where the accelerator was applied too much and the vehicle went into a v-drive and collided with a bottle, etc.

Furthermore, traditional safety fences can be
Because only the safety fence must be raised and lowered, which is cumbersome to operate, vehicles are often delivered to the parking lot without raising the safety fence in case of an emergency or due to accidental forgetting, etc. while moving within the parking lot. The door sometimes opened, which was not completely satisfactory from a safety standpoint.

Therefore, an object of the present invention is to enable smooth getting on and off of a car, and to securely hold the wheels when not getting on or off the car, and to prevent the locking and unlocking of the locking device and the ups and downs of the safety fence. To provide a device for a movable loaner vehicle 11 equipped with a safety fence which can be operated in conjunction with each other and can release the second lock of the vehicle 11 by knocking down the safety fence in an emergency.

[Means for Solving the Problems] According to the present invention, in a car stopper device that prevents the movement of an automobile provided on a pallet, the vehicle stopper device is provided so as to be able to appear on and retract from the running surface of the pallet, and a a movable wheel stop that stops the rolling of the vehicle's wheels when the vehicle is in a protruding state;
a biasing means for urging the car stop to protrude above the running surface; a locking means for locking the car stop in a state in which it projects above the running surface; a safety fence undulating on the side surface of the pallet; A movable car stop device equipped with a safety fence is obtained, characterized in that the lock means and the safety fence are interlocked with each other and a driving device 6 is used to drive the pallet from outside.

[Function] In the case of the n■ dynamic top stop device of the present invention, the wheel stop is provided so as to be able to protrude and retract from the running surface of the pallet, and this wheel stop is always projected from the running surface of the pallet by the biasing means. Since the wheels of the car try to ride on the bollard when driving onto the pallet, the car will be energized.
The first member is pushed down by the wheels. For this reason,
The wheels do not go over the bollard, and the car passes through it smoothly. Then, when the wheel passes the car IF, this car stop protrudes from the running surface again by the biasing means. After the wheels are stopped at a predetermined position by the bollard, the bollard is locked by the locking means and the safety fence is automatically erected on the side of the vehicle.
Even if the pallet is moved, the car will not run away, and even if the car is delivered to the parking lot with the door ajar, the door will be securely stopped by the safety fence and will not open any further.

On the other hand, when taking out the zero-moving vehicle from the pallet, the locking means is driven by an external drive device, thereby releasing the locked state of the vehicle stop and also knocking down the safety fence. Therefore, the car stopper becomes accessible again, and the door can also be opened freely, allowing the driver to get in and drive. At this time, the stopper is pushed down by the middle wheel as described above, so the car smoothly comes out of the pallet.

On the other hand, the locking means can be unlocked not only by the drive device but also by the safety fence. As mentioned above, the safety fence is provided on the pallet and moves with the pallet, so the locking means can be unlocked at any location by manually knocking down the safety fence.

Therefore, in the case of an emergency such as a breakdown, by releasing the locking means using the safety fence, the car stopper becomes accessible and the car can easily move on the pallet by itself.

A sectional view taken along line CC in FIG. 4 shows the locking device in a locked state. 8 is a sectional view taken along the line E in FIG. 1, showing the safety fence, and FIG. 9 is a sectional view taken along the line DD in FIG. 4, showing the driving device of the locking device.

The embodiment will be described above based on FIGS. 1 to 9.

First, referring to FIGS. 3 to 5, a shaft 6 is rotatably supported horizontally on the back surface of the pallet 3 by a bearing 34. As shown in FIG. A pair of car stop frames 9 and 9' are rotatably attached to this shaft 6.

Wheel chocks 7, 7' are fixed on the beams 8, 8' at one end of the wheel frame 9, 9'. This allows the wheel stoppers 7, 7' to be retracted from the running surface of the pallet 3. The other ends of the frame 9, 9' are bent in the opposite direction, and a tension spring 10 is attached between these ends. Due to the tension of the tension spring 10, the car stopper 7.7' always prevents the car from running away from the running surface of the pallet 311. protrude high enough to

Referring to FIGS. 6 and 7, the lock release lever 11 is fixed to a shaft 6, and when the shaft 6 rotates, a T-shaped shaft 12 is opened.
Press the first arm 12a of the.

The T-shaped sunk 12 has a shaft 1 fixed to the back side of the pallet 3.
3 is rotatably attached.

The lock 16 is approximately crank-shaped, and one end is connected to the second arm portion 12b of the T-shaped link 12 by a pin 14, and the other end is freely retractable into a through hole 31 of a support plate 30 provided on the back surface of the pallet 3. It is inserted into.

The lock 17 is also approximately crank-shaped, and one end is connected to the third arm portion 12c of the T-shaped link 12 by a pin 15, and the other end protrudes into a through hole 33 of a support plate 32 provided on the back surface of the pallet 3. It is inserted into the mouth/E. Further, a tension spring 18 is attached to the lock 17 between it and the support plate 32, so that the locks 16 and 17 are always projected in the direction of the beam 8° 8' via the T-shaped sunk 12. It consists of

Referring to FIG. 9, one lever is fixed to the shaft 6.

The lever 21 forms part of a drive device and is fixed to a shaft 22 fixed to the ground side and rotated by a drive source (not shown). This lever 21 is configured to engage with the lever 19 when the pallet 3 comes to a predetermined position, and when the lever 21 rotates, the lever 19 also rotates. The driving device is located below a place (for example, a turntable) where a car is loaded on and off from the pallet 3, and is provided at two locations on one end side and the other end side of the pallet 3.

Referring to FIG. 8, the shaft 6 is connected to a support 5 which is pin-coupled to the safety fence 4 via a lever 6a fixed to the shaft 6. This support column 5 is always biased in the direction of standing up by a spring 20. That is, by this spring 20, when the drive device is not operated to unlock, the shaft 6 rotates, and the lock release lever 11 is rotated from the position shown in FIG. 6 to the position shown in FIG. 7, and is automatically locked. At the same time, the safety fence 4 also automatically stands up from the position shown by the two-dot chain line in FIG. 8 to the position shown by the solid line.

Referring to FIGS. 1 and 2, the n1 movable car stopper equipped with the safety fence of this embodiment is provided in four sets symmetrically on the pallet 3, but the present invention is not limited to this. Two sets may be provided, or two sets may be provided diagonally on the pallet.

Next, the operation of this embodiment will be explained based on the drawings.

The pallet 3 is located at a predetermined location where a drive device is installed, and when a car drives onto the pallet 3, the drive device (not shown) is driven to drive the vehicle as shown by the solid line in FIG.
When the shaft 6 is rotated via the lever 21 and the lever 19, the lock release lever 11 is released by the spring 18 as shown in FIG.
The first arm portion 12a of the T-shaped sunk 12 is pushed down against the pressure. With this movement, the T-shape 12 retracts the locks 16 and 17 from the door of the beam 8.8', so that the locks are in the released state, and with the rotation of said shaft 6, said shaft 6. Since the lever 6a fixed to the lever 6a also rotates clockwise, the safety fence 4 also falls to the position shown by the two-dot chain line in FIG.

In this state, if you drive the car onto the pallet 3 and the wheels 29 of the car try to ride on the bollard 7.7',
As shown in FIG. 5, the torpedo stoppers 7 and 7' are pushed down by the wheels 29 against the springs 10, so the running surface of the pallet 3 becomes 1", so the car can run smoothly on the pallet 3. can do.

The car stops at a predetermined position on the pallet 3, and the front wheels are on the car i! - when the lever 21 shown in FIG. 9 is rotated to the position indicated by the two-dot chain line by driving a drive device (not shown), the force of the spring 20 shown in FIG. The lever 19, shaft 6, and -11 rotate, thereby disengaging the lever 11 from the T-shape sink 12. As a result, the lock 17 is released from the tension spring 18 as shown in FIG. It moves by being pulled by the force, and this movement causes the T-shaped sunk 1
2 move together, and the rotation of this T-shaped sink 12 locks 1.
6 also moves. As a result, the locks 16, 17 each protrude below the beam 8, 8' and prevent the bollards 7, 7 from lowering.
1-. Therefore, the front wheels are securely held by the vehicle +l 7° 7'. Further, by rotating the lever 6a, the safety fence 4 is automatically raised to the side of the vehicle via the support 5 fixed to the lever 6a. In this state, the pallet 3 is moved and the automobile is stored together with the pallet 3 in the parking area.

Please note that the distance between the front and rear wheels of a car varies depending on the car model.
When the front wheels are between the front wheel chocks 7.7', the rear wheels may be on the rear wheel chocks 7.7'. That is,
The rear wheels may be in a state as shown in Figure 5. At this time,
When the lever 21 of the drive device rotates, the lever 19
, shaft 6, and lever 11, they are blocked by the beam 8' and lock 16, as shown by the two-dot chain line in FIG.
17 remains unprotruded.

On the other hand, in the case of an emergency such as a failure of the parking device, when the safety fence 4 is pushed down and the support column 5.5' is brought down, the shaft 6°6' rotates clockwise. At this time, since the safety fence 4 is attached to the lever 6a via a relatively long support 5, it can be easily brought down even with a relatively small force by the principle of leverage.

Hereinafter, since the movable vehicle stop device on the front wheel side and the movable substitute vehicle stop device on the rear wheel side operate in the same way, only the movable vehicle IF device on the front wheel side will be described.

When the shaft 6 rotates in the time=1 direction, the lock release lever 11 fixed to the shaft 6 also rotates from the state shown in FIG. 7 to the state shown in FIG. 6, as described above. This lever 11
The first arm 12a of the T-shape sink 12 is pushed down by the rotation of the locks 16 and 17, respectively.
2, and as shown in FIG. 6, the lock is released. Therefore, at any location, the fence 4 and the posts 5
, 5, the locking device is unlocked and the vehicle can be moved from the pallet 3 to the goods.

[Effects of the Invention] In the movable car stop device equipped with the safety device of the present invention, when the lock is released, the stopper is pushed away by the T-wheel, so when the automatic type gets on and off the pallet, the wheels do not touch the car stop. The car can smoothly get on and off the pallet without having to climb over it, and the car can be locked and
Unlocking and raising and lowering the safety fence can be performed in conjunction with each other, so you never forget to raise and lower the safety fence. Therefore, even if the car is delivered to a parking lot with the door ajar, the car door will not open during movement, and the door will not be broken or the parking device will not be damaged.

Furthermore, the movable car stop device equipped with a safety fence of the present invention can unlock the locking means regardless of the location of the pallet by raising and lowering the safety fence, so that the vehicle can be stopped automatically in an emergency. You can quickly move it around the pallet by running it.
