Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an ajar door accident prevention device for a mechanical multilevel parking system using a vertical circulation drive system.

Conventionally, numerous proposals have been made regarding a mechanism in which a cage is provided with a door ajar accident prevention lever, a drive device is provided in the tower, and the drive device is used to prevent a door ajar accident and operate the bar.

Of these, generally a drive device is installed in the tower on the front or rear side of the cage, and the power of the drive device is transmitted to the door ajar accident prevention lever via a power transmission mechanism installed in the cage. A safety device is used that activates the prevention lever. However, in such a conventional device, a power transmission mechanism must be provided for each cage, and a drive mechanism must be newly installed to operate the door ajar accident prevention lever. The present invention has been made in view of the above points, and it is an object of the present invention to provide a door ajar accident prevention device that does not require a dedicated drive device and power transmission device for operating a door ajar accident prevention lever.

By the way, some mechanical parking systems with an upper compartment for storing cars underground are provided with electric side walkways on both sides of the cage at the entrance/exit where the car is stored for the driver to get off.

The present invention is characterized in that the raising and lowering movements of the side walkway are used to operate a door ajar accident prevention lever provided on the cage. Fig. 1 is a front view showing a conventional top-entry multilevel parking system, in which 1 is a cage, 2, 3
4 is a guide rail that guides the cage; 4 is a side walkway used by car drivers to enter and exit cage 1; 4a, 4b;
A low foot is provided on the side walkway 4, and the side walkway 4 can be moved up and down along a guide 10 by rollers 4a and 4b.

The upper portion of the guide 10 is provided obliquely with respect to the vertical direction so as not to interfere with the movement of the weight 9 and to reduce the upper clearance within the housing.
5 and 5a are electric motors, 6 and 6a are pulleys, 7 is a rope, 8 is a belt, 9 is a weight, and 11 is a guide for the weight 9.

To briefly explain the operation of the cage 1 and the side walkway 4 with reference to FIG. and circulate. In order not to interfere with driving when driving the cage, the side walkway 4 is raised along the guide 10 by the electric motor 5 to the state shown by the two-dot chain line, and when the cage 1 stops at the car loading/unloading entrance 30, the electric motor 5,
5a, the side walkway 4 descends to the state shown by the solid line. Next, an embodiment of the apparatus of the present invention will be described with reference to FIGS. 2, 3, and 4. In the figure, the same reference numerals as in FIG. 1 indicate the same parts. FIG. 2 is a front view showing the structure of the side walkway. A hollow gauze 12 is provided at the upper end of the side walkway 1 on the side of the cage 1, and a pin 13 is inserted into the gauze 12. pin 13
A roller 14 is rotatably attached to the end of the roller.
Further, since a spring 15 and a spring seat 16 are inserted between the gauze 12 and the roller 14, the pin 13 and the roller 14 are slidable horizontally in the A and B directions. FIG. 3 is a side view of the cage showing the structure of the ajar door accident prevention lever attached to the stage of the cage 1.

The half-door accident prevention lever 2 is rotatably supported by one end of slave levers 21 and 22 at the connecting portion 20a at both ends of the door, and the other end of the slave lever 21 is fixed to the side surface of the cage 1. . The square-shaped follower lever 22 is provided with a return spring 22a at the end opposite to 20a, and the bent portion 22b is stopped against the side surface of the cage 1, and is normally held in an upright state by the return spring 22a. FIG. 4 is a diagram showing the state of engagement between the side walkway 4 and the door ajar accident prevention lever 20, and the operation of the device of the present invention will be described below with reference to FIGS. 2 to 4. When the cage 1 is driven to the uppermost position for car entry/exit and stops, the electric motor 5 rotates clockwise (the electric motor 5a rotates counterclockwise) and the pulley 6 rotates clockwise (the pulley 6a rotates counterclockwise) as in the conventional device. counterclockwise) to lower the side walkway 4 along the guide 10. Even if the lowered side walkway 4 continues to move downward, even if the low foot 14 engages the door ajar accident prevention lever 20, the door ajar accident prevention lever 2 continues to move downward.
0 is engaged with a horizontally slidable roller 14 and lowers in conjunction with the side walkway 4. Therefore, the slave levers 21 and 22 rotate clockwise against the spring pressure of the return spring 22a, and sequentially shift to the horizontal state. When the side walkway 4 is positioned right next to the cage 1, the electric motors 5, 5a stop rotating, so that they move with the side walkway 4 and the half-door accident prevention lever 20G also stops in a horizontal state. Therefore, the driver can freely open and close the car door and can take in and out the car. still,
Here, the spring 15 is provided to absorb forces in the A and B directions. Next, when the cage 1 is to be circulated from the car unloading position, the electric motors 5 and 5a are reversely rotated to raise the side walkway 4 along with the guide 10' before the cage 1 starts being circulated.

With this upward movement, the follower lever 22 is moved by the return spring 22.
a, it rotates counterclockwise around the bent portion 22b, and the door ajar accident prevention lever 20 rises to the operating position, making it impossible to open or close the door of the automobile. As can be seen from the above explanation, according to the present invention, the movement of the electric side walkway is used to directly operate the door ajar accident prevention lever, so power for the door ajar accident prevention lever is not required1. A power transmission device for transmitting power can also be made unnecessary, and an extremely simple door ajar accident prevention device can be obtained.

Furthermore, since the roller that directly engages with the door ajar accident prevention lever is provided so as to be slidable in the horizontal direction, even if the side walk moves diagonally and vertically, the horizontal force is absorbed and no problem occurs. In the above explanation, we have described an ajar door accident prevention device that uses the side walkway, but this is not limited to the side walkway, but can also be applied to other operations required when loading and unloading cars, such as opening and closing the Qin entrance door. The exact same effect can be achieved by using the door ajar accident prevention lever to operate.
