BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a safety device for a mechanical parking device.

[0002]

2. Description of the Related Art In general, a mechanical parking device limits the types of cars to be stored, and a building and a parking facility are designed and manufactured based on the maximum size of the limited type of vehicle.

[0003] Even if it is a limited car type, it is dangerous if a car with luggage on the roof of the car, that is, a car with a height exceeding the limit height of the parking facility, is dangerous. Such a fixed height limiting device 1 is provided so that it is physically impossible to enter the warehouse.

[0004] However, in such a fixed type height limiting device, a flexible projection such as an antenna simply bends. Therefore, for example, actual fair 1-2
As disclosed in Japanese Patent Publication No. 2055, an apparatus as shown in FIGS. 3 and 4 has been proposed.

In the drawing, reference numeral 2 denotes an entrance of a parking lot building, 3 denotes a ceiling of the entrance, and 4, 4 'denote loop-shaped support members fixed at appropriate heights on the right and left sides of the ceiling 3. A bar 5 is extended between the doors 4 and 4 'over the entire width of the doorway, and is slidably supported in the depth direction (front-back direction) of the parking lot.

A reflection plate 6 is provided at one end of the bar 5, and a photoelectric device 7 is provided on a side wall of the entrance 2.
As shown in FIG. 4, when the automobile 9 for which the antenna 8 has been forgotten to be lowered attempts to enter the parking lot, first, the antenna 8 is moved to the ceiling 3.
Before touching, the bar 5 touches the bar 5 so as to push the bar 5 toward the back of the parking lot, and the bar 5 is configured to slide even when a slight force is applied.

Therefore, when the bar 5 moves to the far side of the parking lot, the surface of the reflecting plate 6 is tilted, and the light from the photoelectric device 7 is not sent back to the photoelectric device 7, so that the objects exceeding the height limit are placed in the parking lot. You will immediately know that you are trying to break in.

[0008]

However, such a safety device has the following disadvantages. It is a safety device provided on the entrance ceiling when a car enters the warehouse in the first place, and cannot prevent damage when moving the automobile by projecting the antenna at the time of leaving the car. Since the Anna itself is generally tilted backward, even if a force is applied from the top to the bottom at the time of storage, it will bend only elastically without much damage, and in this case, simply press the bar 5 upward. Return to the original state immediately without moving, the safety device does not work after all, the ceiling 3 when leaving the warehouse
As a result, a force (a reverse bending direction) is applied from below to above, causing complete breakage. Since the safety device is provided at a location facing the outside of the parking lot, there is a risk of mischief and the like, and design considerations must be taken. The present invention has been made in view of the above points, and an object of the present invention is to provide a safety device that can easily detect a protruding object having a height higher than a limit height regardless of whether a vehicle enters or leaves a vehicle. .

[0009]

According to the present invention, there is provided a mechanical parking device in which front and rear cage frames are connected to each other by connecting rods and a car is stored on a cage floor. The photoelectric device is provided movably upward, and the photoelectric device is disposed outside the cage frame at a position facing the reflection plate.

[0010]

With the above construction, a protruding object exceeding the limit height can be easily detected regardless of whether the vehicle enters or leaves the vehicle.

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view of a safety device according to the present invention.
FIG. 5 is a partially enlarged perspective view for explaining the operation of the apparatus shown in FIG. 1. In FIG. 5, reference numeral 11 denotes a landing floor 12a, 12b on the entrance side, a cage frame constituting a cage, and a cage frame 12a is on the entrance side (front). The cage frame 12b is located on the side opposite to the entrance (rear). Reference numeral 13 denotes a floor plate constituting the cage, and reference numeral 14 denotes a connecting rod for connecting the cage frame 12a and the cage frame 12b, both ends of which are suspended by a drive chain (not shown).

Reference numeral 15 denotes an operating member having a U-shaped cross section. One end of the operating member is rotatably supported on the connecting rod 14 like a hook, for example, and a reflecting plate 16 is provided on the upper surface. Reference numeral 17 denotes a support member for supporting the operation member 15 so that the other end of the operation member 15 does not hang down by its own weight.

Reference numeral 18 denotes a photoelectric device provided in the parking lot (outside the cage frame) facing the reflector 16 of the operating member 15,
A light emitting device and a light receiving device are built in. The normal state of the operating member 15 is held at the same height position as that of the well-known height limiting device or at a slightly higher position by the support member 17 in a horizontal state, and the light emitted from the photoelectric device 18 is reflected by the reflection plate. The light is reflected at 16 and returned to the photoelectric device 18.

In the device of the present invention having such a configuration, for example, if the vehicle 9 is to be taken out of the vehicle in the direction of arrow A shown in FIG.
Touches the operating member 15 and bends along the U-shaped cross section of the operating member 15, and thus tries to push the operating member 15 upward.

Then, since the operating member 15 is configured to rotate even when a slight force acts, the reflecting plate 1
6 also moves above the arrow B, and the photoelectric device 18
Will no longer be sent back to the photovoltaic device 18 so that it is immediately apparent that anything above the limit height is about to leave the warehouse. Even if the movement of the vehicle 9 is a parking operation, since the operating member 15 moves upward, it is possible to detect a vehicle having a height higher than the limit height in the same manner.

After the detection, as is well known, a display that calls attention to a driver or a manager, an alarm is sounded, and an accident is prevented by interlocking so that the parking device cannot be driven. Can also be done easily.

FIG. 6 is a partially enlarged view showing another embodiment of the present invention. In FIG. 6, the same reference numerals as those in FIG. 5 denote the same parts, and 25 is an elastic body such as rubber. This is a round bar-shaped operation bar, one end of which is fixed to the connecting rod 14 by baking or the like, is supported by a support member 17, and the other end is freely movable in any direction when a force is applied. The reflector 16 is fixed to the upper surface in the same manner as in the above embodiment.

Therefore, the antenna 8 and the like are connected to the operation bar 2.
When the touch panel 5 is touched, the surface of the reflection plate 16 is tilted, and the light from the photoelectric device 18 is not sent back to the photoelectric device 18. can do.

[0019]

As described above, according to the present invention, a projecting object made of an elastic body such as an antenna which is tilted in advance in any direction can be easily operated in the same manner as when the vehicle enters and leaves the vehicle. Therefore, the device can be prevented from being damaged. Further, since the apparatus itself is mounted on the cage, the size of the cage can be as small as necessary, and the displacement of the landing position of the cage is not affected at all.
