Description

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

Conventionally, many 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 operates the door ajar accident prevention lever. 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 device 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 top entry type mechanical parking systems that store 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 the figure, 1 is a cage, 2 and 3 are guide rails that guide the cage, and 4 is a rail that guides the car when the driver enters and exits the cage 1. Side walkway to use, 4
A and 4b are rollers provided on the side walkway 4, and the side walkway 4 can be moved up and down along the guide 10 by the rollers 4a and 4b. Furthermore, guide 1
0 is provided obliquely to the vertical direction in the upper part so as not to interfere with the movement of the weight 9 and to reduce the upper clearance within the tower. 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. Cage 1 is easily explained in Figure 1.
To explain the operation of the cage 1 and the side walkway 4, the cage 1 is supported by a chain (not shown) wrapped around the upper and lower sprockets (not shown), and the cage 1 is supported by the rail 2,
3 and circulate. When driving the car, the side walkway 4 is raised along the guide 10 by electric motors 5 and 5a to the state shown by the two-dot chain line, and when the car 1 stops at the car loading/unloading entrance 30, the electric motors 5 and 5a As a result, 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 and guide. First, regarding the side walkway 4, a bracket 12 is provided at the upper end of the side walkway 4 on the side of the cage 1, and the bracket 12 is integrally formed with a shaft 12a. A cylindrical and hollow roller 13 is rotatably attached to the end of the shaft 12a. On the other hand, the guide 100 has a dogleg shape bent at the middle part, and the upper part is arranged vertically so as not to interfere with the movement of the weight 9 and to reduce the upper clearance inside the tower. The lower part where the side walkway 4 and the door ajar accident prevention lever 20 interfere with each other is provided vertically.

FIG. 3 is a side view of the cage 1 showing the structure of the ajar door accident prevention lever attached to the side of the cage 1.
The door ajar accident prevention lever 20 has connecting parts 20a at both ends.
is rotatably supported by one end of slave levers 21 and 22, and the other end of slave lever 21 is pivotally fixed to the side surface of cage 1. Follower lever 2 with a square shape
2 is provided with a return spring 22a at the end opposite to 20a, and the bent portion 22b is axially aligned with the side surface of the cage 1.
Normally, it is held in an upright state by a return spring 22a.

Figure 4 shows the side walkway 4 and the door ajar accident prevention lever 20.
FIG. 4 is a diagram showing a state of engagement with the device, 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 top car loading/unloading position and stopped, the electric motor 5 rotates clockwise as in the conventional device (the electric motor 5a rotates counterclockwise).
Then, the pulley 6 is rotated clockwise (the pulley 6a is rotated counterclockwise) to lower the side walk 4 along the guide 100 according to the present invention. On the side walkway 4 that has descended, the roller 13 is the door ajar accident prevention lever 2
Even if it is engaged with 0, the downward movement continues, so the door ajar accident prevention lever 20 is lowered in conjunction with the side walkway 4 while being engaged with the roller 13. 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 and 5a stop rotating, so that the door ajar accident prevention lever 20 stops in a horizontal state in conjunction with the side walkway 4. Therefore, the driver can freely open and close the car door and can take in and out of the car.
Here, the width l of the roller 13 is made sufficiently larger than the diameter d of the door ajar accident prevention lever 20, so that the roller 13 can operate the door ajar accident prevention lever 20 even if the landing position of the cage 1 shifts to some extent. At the same time, the guide 100 is provided vertically in the lower part where the roller 13 and the door ajar accident prevention lever 20 interfere with each other, so that excess force in the horizontal direction is not transmitted to the door ajar accident prevention lever 20.

Next, when the cage 1 is circulated from the car loading/unloading position, the electric motors 5 and 5a are reversed to move the side walkway 4 to the guide 10 before the cage 1 starts circulating.
Raise it towards 0. With this upward movement,
The slave lever 22 is moved to the bent portion 22 by the return spring 22a.
b, and the door ajar accident prevention lever 20 rises to the operating position, making it impossible to open or close the car door.As can be seen from the above description, according to the present invention, the electric Since the door ajar accident prevention lever is directly operated using the motion of the side walkway, power for the door ajar accident prevention lever is not required, and a power transmission device for transmitting power can also be eliminated. moreover,
Since the guide for guiding the side walkway is installed vertically in the lower part where the side walkway and the door ajar accident prevention lever interfere with each other, it is difficult to apply extra horizontal force to the ajar accident prevention lever, and even if it is applied, The extra force can be absorbed by smoothing the surface of the roller, which has a width sufficiently larger than the diameter of the door ajar accident prevention lever.
