[Industrial applications]

 The present invention relates to a car lock device.

[0002]

[Prior art]

 In toll parking lots, car lock devices have been put to practical use in recent years in order to prevent free parking and collect tolls reliably.

An example of such a car lock device is shown in FIGS. 10 and 11. That is, the curl lock device a is installed near the ground and is fixed to a horizontal shaft b which is rotatable by an actuator (not shown), and a pillar d standing on one side of the flap c. A housing e fixed above is provided, and the housing e is provided with a charge display portion f and a coin insertion portion g. Further, h is a photo-transmitter of a photoelectric tube, and i is a photo-receiver of the photo-tube, and it is possible to detect that the car j has entered the parking compartment by the light transmitter h and the photoreceiver i. .

In the figure, k is a tread arranged behind the flap c along the horizontal axis b.

When the vehicle is not parked in the predetermined parking section, the flap c of the car lock device a in the parking section is lying down, and when the vehicle j attempting to park enters the parking section. , The wheels of car j get over the tread k and the flap c.

At this time, the light sent from the light transmitter h to the light receiver i is blocked by the car j, so that it is detected that the car j has come in, and the actuator is activated. The vehicle j is locked by rotating the horizontal shaft b and raising the flap c.

When the car j goes out of the parking area and a predetermined amount of coins is inserted into the housing e from the coin insertion part g, the actuator is activated in response to the signal and the horizontal axis b is rotated to cause the flap. c falls over. Therefore, the vehicle j can go over the flap c and the tread k to start outside the parking area.

[0008]

[Problems to be solved by the device]

 In the car lock device a, since the actuator is driven not only when the flap c is laid down but also when it is erected, extra power is required, which is not preferable in terms of energy saving. In some devices, the force of the torsion spring is used to raise the flap c. However, the torsion spring is an auxiliary device, and the flap c is raised when the actuator is not driven. However, there is a problem in that significant energy saving cannot be achieved in this case.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a car lock device that does not require an actuator to be activated when the flap is raised.

[0010]

[Means for Solving the Problems]

 The present invention relates to a car lock device equipped with a flap for preventing a parked vehicle from moving out of a parking compartment by standing up on a rotatable horizontal shaft. An arm extending outward in the direction is attached, and a resilient body is connected to the arm so as to rotate the horizontal shaft in the direction in which the flap stands.

[0011]

[Action]

 Since the horizontal shaft is rotated by the pulling force of the elastic body via the arm and the flap is erected, electric power for driving the actuator is not required when the flap is erected.

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

1 to 9 show an embodiment of the present invention, and a car lock device 1 of this embodiment includes a flap device 2 and a charge adjustment device 3 as shown in FIG.

Details of the flap device 2 are shown in FIGS. That is, a plurality of brackets 5, 6, 7 are installed on the base plate 4 arranged on the ground, and the horizontal shaft 9 is rotatably supported by the bearing 8 attached to each bracket 5, 6, 7. A flap 10 extending in the longitudinal direction of the horizontal shaft 9 is attached to the outer periphery of the horizontal shaft 9 so as to be located between the brackets 6 and 7. When the horizontal shaft 9 is rotated and the flap 10 is laid down, the flap 10 is inclined diagonally downward with the horizontal shaft 9 side as the apex, as shown by the solid line in FIG. When they are upright, they can be inclined diagonally upward with the horizontal axis 9 side as the lower point, as shown by the phantom line in FIG.

Further, on the base plate 4, there is installed and fixed a tread plate 11 having substantially the same length as the flap 10 and extending obliquely downward in a direction away from the flap 10 with respect to the horizontal axis 9 as a reference. When lying down, the flap 10 and the tread 11 form a chevron with the horizontal axis 9 as the apex.

A sprocket 12 is mounted on the horizontal shaft 9 so as to be located between the brackets 5 and 6, and as shown in FIG. 4, the sprocket 14 and the sprocket 14 mounted on an actuator 13 such as an electric motor installed on the base plate 4. An endless chain 15 is hung between the and 12.

As shown in FIG. 5, a boss 17 to which an arm 16 projecting outward in the longitudinal direction of the horizontal shaft 9 is integrally fitted is externally fitted to the side of the horizontal shaft 9 close to the bracket 5, and Between the tip of the frame 16 and the horizontal beam 18 installed above the horizontal shaft 9, when the flap 10 is erected, the outer end of the flap 10 in the radial direction of the horizontal shaft 9 is directed obliquely upward. A coil spring 19 for rotating is arranged.

As shown in FIG. 6, a portion of the horizontal shaft 9 between the sprocket 12 and the boss 17 is provided with a plurality of semicircular concave grooves 20 on the outer periphery over a range of approximately 90 degrees for locking. The cam 21 is externally fitted, and a bracket 22 is arranged in the vicinity of the cam 21 such that the tip of the cam 21 is sandwiched from both sides in the longitudinal direction of the horizontal shaft 9 as shown in FIGS. 7 and 8. A long pin 23 formed horizontally on the bracket 22 in the radial direction of the cam 21 slides along the long groove 23 to move back and forth, and can be inserted into and removed from the groove 20 of the cam 21. 24 is inserted.

When the flap 10 is laid down as shown by the solid line in FIG. 3 and is inclined obliquely downward from the horizontal shaft 9 side toward the tip, the lock pin 24 is in the groove 20 of the cam 21. The lower end step portion 25 of the outer periphery of the cam 21 engages with the edge portion of the base portion 26 of the bracket 22 so that the lower end groove portion 20 of the cam 21 can be fitted into the lowermost groove portion 20 of the lock pin. The rotation of the cam 21 can be restricted so as not to be located above 24.

A solenoid 28 is installed on another bracket 27 installed behind the bracket 22, and the tip of the movable part of the solenoid 28 is connected to a lever 29 fixed horizontally to the outer peripheral part of the lock pin 24. The lock pin 24 is always cammed between the lever 30 fixed vertically downward to the outer periphery of the lock pin 24 and the tip of the bracket 31 projecting downward of the horizontal shaft 9 in front of the bracket 22. A coil spring 32 for pulling to the 21 side is provided.

Two limit switch dogs 33 and 34 are externally fitted to a portion of the horizontal shaft 9 between the bracket 6 and the sprocket 12, and the flap 10 is laid down. If the limit switch dog 33 is operated, the limit switch 35 can be operated, and if the flap 10 is upright, the limit switch dog 34 can be operated the limit switch 36. Further, although not shown, a limit switch for confirming entry is provided on the base plate 4 and is operated when the wheels of the vehicle 37 ride on the lying flap 10 and the flap 10 is deformed.

The charge adjusting device 3 includes a casing 38 and an upper part of the casing 38 in which respective parts other than the flap 10 attached to the horizontal shaft 9 of the flap device 2, the actuator 13, the solenoid 28 and the like can be stored in the lower part. The casing 38 is provided with a not-shown arithmetic and control unit and the like, and a casing 38 is provided with a power lamp 39, a charge display section 40, a coin insertion section 41, a bill insertion section 42, a change payout section 43, and the like. ing.

When the vehicle has not entered, the flap 10 is rotated by the actuator 13 and is lying down as shown by the solid line in FIG. 3, and the limit switch dog 33 is provided with the limit switch as shown in FIG. Although 35 is turned on, the limit switch dog 34 has the limit switch 36 turned off, and the limit switch for confirming entry is also turned off. Therefore, the actuator 13 is stopped, the solenoid 28 is turned off, and the lock pin 24 is pulled by the coil spring 32 and fitted into the lowest groove 20 of the grooves 20 of the cam 21 as shown in FIG. The top 10 is in a locked state.

For example, when the vehicle 37 enters the flap device 2 from the side of the tread 11 and the wheels pass over the tread 11 and ride on the flap 10, the weight of the vehicle causes the flap 10 to bend, and the entry confirmation (not shown) is performed. Limit switch is turned on. For this reason, after a lapse of a certain time, the solenoid 28 is actuated, the lock pin 24 overcomes the drag force of the coil spring 32, is separated from the groove 20 of the cam 21, and is retracted to the proximal end side of the long groove 23. Rotational force is applied to the horizontal shaft 9 through the arm 16, so that the horizontal shaft 9 rotates clockwise in FIGS. 3 and 5, and the flap 10 moves as shown by the phantom line in FIG. Standing diagonally upward with the side as the reference, the limit switch dog 34 turns on the limit switch 36. Therefore, the solenoid 28 is turned off, the lock pin 24 is pulled by the pulling force of the coil spring 32 and slides in the long groove 23, and is positioned above the lowest groove 20 of the grooves 20 of the cam 21. The flap 10 is fitted in the groove 20, and thus the flap 10 is locked in an upright state, and the car 37 is also stopped in the parking compartment and is in the locked state. Which groove 20 of the cam 21 the lock pin 24 fits into depends on the vehicle height of the vehicle 37 and the like.

Since the flap 10 is erected by the pulling force of the coil spring 19 and the actuator 13 does not need to be operated, power consumption is saved and energy can be saved. Further, since the flap 10 is upright, the car 37 cannot go out of the parking area, and the fare adjustment device 3 is provided with the casing 38, so that the appearance is good.

When the car 37 goes out of the parking area, the charge is paid to the charge adjustment device 3 from the coin insertion portion 41 or the bill insertion portion 42. Then, when the change is required, the change is dispensed from the change dispensing unit 43 and the solenoid 28 is actuated, the lock pin 24 is pulled by the solenoid 28, disengaged from the groove 20 of the cam 21, and released. The racket 22 retreats toward the base end side of the long groove 23, then power is supplied to the actuator 13 to activate the actuator 13. Therefore, the horizontal shaft 9 overcomes the drag force of the coil spring 19 through the sprocket 14, the chain 15, and the sprocket 12, and rotates counterclockwise in FIG. 4, and the flap 10 moves from the position of the phantom line in FIG. 3 to the position of the solid line. Move to and probate. Then, when the limit switch dog 33 turns on the limit switch 35, the actuator 13 stops, the solenoid 28 also turns off, and the lock pin 24 is pulled by the coil spring 32 to move to the groove 20 at the lowermost end of the cam 21. When the flap 10 is fitted, the flap 10 is locked in a lying state in which the flap 10 is inclined obliquely downward from the horizontal shaft 9 side. For this reason, the vehicle 37 can oscillate out of the parking compartment by riding over the flap 10 and the tread 11 of the flap device 2.

In the embodiment of the present invention, the limit switch is used to confirm the entry of the vehicle. However, it is also possible to use a photoelectric tube equipped with a light-transmitting section and a light-receiving section. It is needless to say that any conventionally known lock mechanism can be used to prevent rotation, and that various modifications can be made without departing from the scope of the present invention.
