Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a safety device for a parking facility, and more particularly to a parking facility having an underground or semi-underground structure, in which an elevator passage at a vehicle entry level position is opened by raising and lowering a tray. The present invention relates to a safety device for parking equipment suitable for accident prevention.

[0002]

[Prior Art] Underground or semi-underground parking facilities,
The tray on which the vehicle can be mounted moves the hoistway to the storage position of the vehicle to store the vehicle, or takes the stored vehicle and returns to the loading level position. When the elevator on which the tray of this type of parking equipment is placed is moved up and down, the elevator passage at the vehicle entry level is open. In this state, when the vehicle breaks through the parking entrance door due to a runaway or the like and enters, the elevator passage is opened,
There is a risk of crashing and people falling inside the hoistway.

From such a point of view, it has been proposed to close the tray lifting passage when the tray moves up and down and moves from the loading level position. For example, in Japanese Examined Patent Publication No. 6-74656, a shutter that opens and closes an elevating passage by using the elevating drive force of a tray is provided, and a dog provided in a tray elevating chain is engaged with a guide provided at a rear edge of the shutter. Thus, when the tray is lowered, the rear edge of the shutter is pushed out to be closed, and when the tray is raised, the rear edge of the shutter is pulled and moved to open the tray.

[0004]

However, since the above-mentioned conventional safety device provided in the parking facility is of the shutter system, noise peculiar to the shutter is generated during the operation at the time of opening and closing, and the tip of the shutter is closed when the shutter is closed. Since it cannot be pulled and moved, it may not be possible to feed the tip end due to the meandering of the shutter, and there is a problem that smooth opening / closing operation is difficult. Furthermore, since the shutter opening / closing operation is performed by raising / lowering the tray, the capacity of the raising / lowering drive device must be increased. In particular, due to the opening / closing resistance of the shutter, the raising / lowering drive of the tray is interlocked to prevent smooth raising / lowering operation. If it moves in a meandering manner, the shutter guide will not function, and as a result, the tray elevating device will be constrained, and a secondary adverse effect will occur. Furthermore,
With the shutter opening and closing method, when there is a runaway approaching vehicle,
A large inertial load is generated together with the vehicle body load, which causes a large impact force with the shutter as a rigid body, which is not sufficient in terms of protecting the occupant.

In view of the above conventional problems, the present invention makes it possible to open and close the opening of the ascending / descending path of the tray with a small driving force, and to greatly reduce the impact force even when a runaway vehicle enters. It is an object of the present invention to provide a safety device for a parking facility that has been set. Further, another object of the present invention is to provide a safety device for a parking facility having a structure in which the opening / closing operation noise is extremely small, the opening / closing operation is performed smoothly, and the opening / closing failure does not occur.

[0006]

In order to achieve the above object, a safety device for a parking facility according to the present invention is an underground or semi-underground equipped with a tray on which a vehicle is mounted and which can be driven to move up and down an aisle. A safety device used for a structured parking facility, which is provided with a parallel chain wound around a sprocket arranged at a corner of a hoistway near the vehicle boarding level, and the hoistway of the tray is closed to the chain. A possible opening / closing net is attached, a balance weight is connected to the end of the chain, and a rotary drive motor is connected to the sprocket to detect that the tray has moved up and down from the loading level to a set height. Thus, the control means for driving the rotation drive motor to move the opening / closing net to the passage crossing position may be provided. It is. In this case, the main net of the opening / closing net may be made of wire.

[0007]

According to the above structure, since the pit entrance is opened and closed by the opening and closing net at the entry level part of the pit which is the ascending and descending passage of the tray, even if a runaway vehicle enters, the load It is possible to effectively prevent a vehicle crash while absorbing the inertia well. In particular, since the bending effect of the opening / closing net is great, the impact force is greatly reduced, and the effect of ensuring the safety of the occupant is great. In addition, the opening and closing net has a chain installed on both side edges wound around a sprocket and a balance weight is provided at the end of the chain, so opening and closing operations with a small driving force are possible and noise is extremely low. Become. Further, since the opening / closing net is attached between the parallel chains, the opening / closing failure does not occur, and even if the opening / closing cannot be performed, the operation of the tray itself is not affected. Therefore, even if the vehicle is loaded on the tray and the net opening / closing is stopped, the net opening / closing can be repaired manually by moving the vehicle from the tray to the storage position to make it safe. Can be secured.

The opening / closing net has only to have a size capable of covering the opening area of the ascending / descending passage, and may be one capable of being bent to absorb impact. In particular, a wire net is highly safe because it is made of a metal material, but it is also possible to use a net made of a resin fiber or the like having high tensile strength.

BEST MODE FOR CARRYING OUT THE INVENTION Specific embodiments of a safety device for a parking facility according to the present invention will be described below in detail with reference to the drawings. 1 and 2 are explanatory views before and after the operation of the safety device for a parking facility according to the embodiment, and FIG. 3 is a perspective view showing a configuration of a wire net for crash prevention.

This embodiment is applied to an elevator type parking facility having an underground structure, and a hoistway 16 through which a tray 14 on which a vehicle 12 can be mounted is lifted is opened on the floor. Although not shown in detail, the tray 14 can be vertically moved up and down by an elevating drive chain 18, and is placed on an elevator 20 to which the elevating drive chain 18 is connected and is moved up and down together with it. Such a tray 14
When the parking door 22 is opened, the vehicle 12 travels and is placed on the vehicle, but at this time, the tray 14 is moved up to the loading level 10 position and stopped (see FIG. 2). This position is the uppermost position in the case of the embodiment, and when the tray 14 is moved down to store and store the vehicle, an opening is formed at the boarding level 10 portion of the hoistway 16, and thus this boarding is performed. A net opening / closing mechanism for opening / closing the hoistway opening at the level 10 position is equipped as a safety device.

The specific construction of the net opening / closing mechanism is shown in FIG. A vehicle entrance / exit room 24 communicating with the outside is formed by the parking entrance door 22, and a hoistway 16 is formed in a portion of the room corresponding to the floor surface to move the tray 14 up and down. Vehicle storage room 2 of hoistway 16
Chain sprockets 26 are arranged at the four corners of the opening to 4, and a parallel chain 28 is wound around each pair of sprockets 26 as one set. In this example, there are an entrance side chain 28F along the entrance door 22 and a back side chain 28R along the back wall surface of the vehicle loading / unloading chamber 24. Each chain 28 has a length that is at least twice the width of the hoistway 16, is parallel to the opening surface of the hoistway 16, and is hung vertically after being wound around the sprocket 26. A balance weight 30 is attached to each end of each of the chains 28F and 28R. A wire net 32 is attached so as to fill the space between the parallel chains 28.
It has a rectangular size with width and length dimensions that allow the opening of the hoistway 16 to be closed. Therefore, the parallel chains 28 are formed on both side edges of the wire net 32.
Is linked to Further, the wire net 30 is set so as to be arranged on one side of the length center of the parallel chain 28, whereby the sprocket 26 is rotated to move the chain 28, whereby the wire net 32 is opened in the hoistway 16. There are two positions, a position for covering the portion (FIG. 1) and a position for the wire net 32 to open the opening along the vertical wall surface portion of the hoistway 16 (FIG. 2). Since the wire net 32 is eccentrically arranged in the half of the chain length, the balance weight 30 is designed to reduce the weight of the wire net 32 on the mounting side. The wire net 32 is the vehicle 1
2 is a net structure in which metal wires are woven so as to sufficiently bear the weight of 2, so that the impact force when a runaway vehicle enters can be alleviated by providing flexibility, and the front and rear of the sprocket 26 are It is set so that it can bend when moving.

In order to open and close the wire net 32, a pair of coaxial sprockets 26D and 26D around which front and rear chains 28F and 28R are wound are coaxially coupled, and a motor 34 for rotationally driving the sprockets 26D and 26D is also coupled. ing. The rotation drive motor 34 causes the chain 28
And the wire net 32 is driven in and out of the opening of the hoistway 16. A control means 36 for controlling the rotation of the rotary drive motor 34 is provided (see FIG. 1), in which the tray 14 is lowered, and the mounted vehicle 12 is moved to a necessary and sufficient position from the opening of the hoistway 16. When the time is detected, the motor 34 is operated and the wire net 32 closes the hoistway 16. In order to detect whether or not the tray 14 has descended to a position sufficient to move the wire net 32 closed, a tray position detecting means 38 is provided in the elevator 40 and a sensor 40 provided in the middle of the hoistway 16. Formed by the triggered trigger 42. This can be configured by a mechanical sensor such as a limit switch and a kicking lever, an optical sensor such as a photoelectric sensor and a light emitting diode, or a magnetic detecting means such as a magnetic sensor and an operating magnetic body, or other means. The signal for detecting the lowered position of the tray 14 by the sensor 40 is output to the control means 36, and the control means 36 simultaneously inputs the closing signal for the door 22.
When the door opening / closing cylinder 44 is used as shown in the figure, the closing signal of the door 22 may be detected by capturing the rod position signal. The control means 36 operates the rotation drive motor 34 by detecting the lowered position of the tray 14 and the closing signal of the door 22 to close the hoistway 16 by the wire net 32. On the contrary, when the tray 14 moves upward from the vehicle storage position and moves, the control means 36 inverts the closing signal to determine that it is an upward movement, and the reverse rotation operation of the motor 34 causes the wire net. 32 is moved to the open side.

In order to regulate the moving position of the wire net 32, a weight stopper 46 is provided in the middle of the path of the chain 28 to prevent danger. In the safety device for the elevator-type parking facility thus configured, as shown in FIG. 2, the vehicle door 12 is opened by opening the parking door 22 while the tray 14 is moved to the loading level 10 position in advance. By moving the tray, the tray 14
The vehicle 12 is mounted on the top. When the vehicle 12 is parked and stored, the door 22 is closed and the elevator 20 having the tray 14 is moved down. When the tray 14 descends and the vehicle 12 reaches a position far away from the hoistway 16, the tray position detection means 38 detects this and outputs it to the control means 32. Control means 3
2 receives the closing signal of the door 22 and operates the rotary drive motor 34 by inputting both signals. As a result, the chain 28 is moved to the left in FIG. 2, the wire net 32 is pulled out, and the opening of the hoistway 16 is closed as shown in FIG. Then, when the tray 14 turns up, the down detection signal precedes, so the control means 36 determines this and determines that it is up movement,
A reverse rotation signal is sent to the rotary drive motor 34 to pull in and operate the wire net 32, and the storage state shown in FIG. 2 is obtained.

According to the above-mentioned embodiment, since the opening portion of the hoistway 16 is opened and closed by the wire net 32, the elastic function of the net provides a high impact absorbing power.
It is possible to ensure the safety of passengers even when a runaway vehicle enters. The wire net 32 itself has a high bending function and is lightweight, and in addition to the balance weight 30, the drive operation force of the motor 34 is reduced. As a result, the opening / closing operation of the wire net 32 is performed lightly. Since the wire net 32 is opened and closed by the chain 28 traveling by the sprocket 26, the operating sound is only the meshing sound of the sprocket portion, and almost no noise is generated, and the operation is quiet.
