JP2000204786A - Device for blocking leaving of parked motor vehicle - Google Patents

Abstract

PROBLEM TO BE SOLVED: To prevent unfair leaving of a parked motor vehicle by providing a lock portion for locking a parked motor vehicle, a drive means for selectively driving the lock position for the parked motor vehicle to a raised lock position or lay down lock position after the ingress of the parked motor vehicle, and by installing a freely rotatable lock roller. SOLUTION: When a motor vehicle enters a parking space and this is sensed by a vehicle sensor, then a drive mechanism is driven by a control circuit of a drive portion 12. By the drive of the drive mechanism, a rotating shaft 14 of the lock portion 11 rotates and a roller support member 15 and a lock roller 16 rise in one united body to the lock position. In this lock state, if a parked motor vehicle tries to leave the parking space in an unfair manner, then the wheels contact the lock roller 16 and try to press down the lock roller 16 or get it over. But by the rotation of the lock roller 16, the wheels slip and both pushing down and getting over against the lock roller 16 become impossible and an advance of the parked motor vehicle is blocked. Thus, unfair leaving can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for preventing a parked vehicle from leaving, which is used in an unmanned management type toll parking lot or the like, and more particularly to a technique for preventing unauthorized exit.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 3, a pay parking lot of an unmanned management system is provided with a parking fee collection device 1 and an exit preventing device 3 for locking a parked vehicle by a lock plate 2. Parking equipment is used.

In this parking device, as shown in FIG. 3, a lock plate 2 of a retraction preventing device 3 is disposed between tires before and after a vehicle parked in a parking space 4. Parking space 4
When a vehicle sensor (not shown) detects a parked vehicle that has entered the vehicle, the lock plate 2 stands up and is locked, thereby preventing the vehicle from leaving. When a predetermined parking fee is input to the parking fee collection device 1, the lock plate 2 falls down to an unlocked state, and the parked vehicle can exit.

[0004]

However, in such a lock plate system, the standing lock plate 2 is depressed by stepping on the tire with a tire, or the lock plate 2 cannot be pressed down.
In this case, the vehicle itself can climb up and get over it, and it is possible to leave illegally without paying a parking fee. Such an illegal exit is advantageous for a vehicle having a large tire diameter or a vehicle having a low ground height where the standing height of the lock plate 2 is limited, and is referred to as a recent RV (recreational vehicle) vehicle. With the increase in large four-wheel drive vehicles and the like, the number of vehicles leaving illegally has increased.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a parked vehicle exit prevention device that has an improved effect of preventing illegal exit of a parked vehicle.

[0006]

According to the first aspect of the present invention, there is provided a lock portion for locking a parked vehicle, and the lock portion after the parked vehicle enters the lock position. And a driving means for selectively driving the unlocked position of the parked vehicle, wherein the lock portion is provided with a rotatable lock roller.

In this configuration, when the locked portion is in the upright locked position, if the parked vehicle tries to erroneously exit, the wheels slip due to the rotation of the lock roller, and the parked vehicle cannot move forward. Become like

[0008]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows the structure of the exit prevention device 10 of the present embodiment.

Referring to FIG. 1, a retraction preventing device 10 includes a lock portion 11 and a driving portion 12. The arrangement of the lock unit 11 and the drive unit 12 is installed in the parking space 4 as in the conventional case as shown in FIG.

The lock portion 11 includes a base portion 13 installed on an installation surface, a rotation shaft 14 whose both ends are rotatably supported on both end walls of the base portion 13, and a rotation shaft. A roller support member 15 fixed to the roller support member 14;
5 is provided with a lock roller 16 that is rotatably supported by the shaft. The roller support member 15 has, for example, a base end fixed to the outer peripheral portion of the rotation shaft 14 by welding, is integrated with the rotation shaft 14, and has a concave end at the front end. The lock roller 16 is rotatably supported on both end walls of the concave portion on the distal end side of the roller support member 15.

The drive unit 12 includes a drive mechanism including an electric motor or the like which selectively drives the lock unit 11 to a locked position in which the lock unit 11 is upright and an unlocked position in which the lock unit 11 is folded, in a case 21, and a vehicle sensor (not shown). And a control circuit for controlling the drive mechanism so that the lock portion 11 stands up based on the sensing signal output by the container.

The drive mechanism is constituted by a drive mechanism represented by Japanese Patent Application Laid-Open No. 1-54509, and a crank 23 is mounted on a drive shaft 22.
The rotating shaft 14 is connected to 3 via a link 24 and a crank 25. Therefore, the driving force of the driving mechanism is
2, transmitted to the rotating shaft 14 via the crank 23, the link 24 and the crank 25, and the roller support member 15 and the lock roller 16 are driven. Reference numeral 26 in FIG. 2 denotes a stopper that regulates the upper limit ascending position of the roller support member 15, and the roller support member 15 is further moved by abutment of a locking piece 15 </ b> A provided on the base end side of the roller support member 15. Avoid rising.

Next, the operation of the exit preventing device 10 according to the present embodiment will be described with reference to FIG. When the parked vehicle enters the parking space and a vehicle sensor (not shown) detects the parked vehicle, the drive mechanism is driven by the control circuit of the drive unit 12. By the drive of the driving mechanism, the rotation shaft 14 of the lock portion 11 rotates, and the roller support member 15 and the lock roller 16 stand up integrally as shown by the solid line in FIG. Position.

If the parked vehicle attempts to leave the locked state in this locked state, the wheel 30 comes into contact with the lock roller 16 as shown in FIG. However, the rotation of the lock roller 16 causes the wheels to slip, so that the lock roller 16 cannot be pushed down or climbed over, thereby preventing the parked vehicle from moving forward.

When a predetermined parking fee is input to the parking fee collection device 1, a driving mechanism is operated by a control circuit of the driving unit 12, and the roller support member 15 and the lock roller 16 are rotated by the rotating shaft 1.
As in the conventional case, the turning of the lever 4 brings the vehicle to the unlocked position shown by the chain line in FIG. 2 so that the parked vehicle can exit.

[0016]

As described above, according to the first aspect of the present invention, since the freely rotatable lock roller is provided, the wheel slips when an illegal retraction is attempted, and the lock roller is pushed down and climbs over. Can be prevented, and illegal exit can be prevented.
