The entire 0 moves in the X1 direction, and the shaft 5 rotates via the cam 4 that engages with the pin 9 provided on the mechanism body 10.
Since the flap 3 provided on the shaft 5 is biased in the standing direction by the winding spring 5, the elastic force of the winding spring 5 is released in response to the rotation of the shaft 5, and the elasticity of the winding spring 5 causes the flap 3 to move. The flap 3 stands up. When the flap 3 comes into contact with a part of the vehicle and is no longer erected, the main body moving member 11 in the mechanism main body 10 moves to the cam drive member 7 side, the limit switch 14 operates, and the rotation of the motor M is stopped. Stop. When the screw rod 8 is rotated in the reverse direction, the mechanism body 10 moves in the Y1 direction to lower the flap 3 against the elastic force of the winding spring 5, and another limit is placed at the position where the flap 3 is lowered to a predetermined height. The switch 15 operates and the motor M stops.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a lock type parking device, and more particularly, to a lock type pay parking device in which an operating mechanism of a lock operating plate can be downsized and an appropriate operation can be performed according to a vehicle type.

[0002]

[Prior art]

 A parking device has been proposed which prevents unauthorized exit of a vehicle by locking the tires of the parked vehicle. 6 and 7 show the operation of this parking device. The vehicle C that has entered a predetermined parking area gets over the crossover plate 50 and the flap 51, which is a rocking plate for locking, and stops between the car stops 52. In this state, various sensors such as an infrared sensor detect the entry stop of the vehicle, and the flap 51 stands up as shown in Fig. 7 to lock the vehicle. (Not shown). As a result, the flap 51 is lowered to the position shown in FIG. 6 and the vehicle can exit.

The parking device having the above-mentioned mechanism basically needs only to be installed in a parking place, and since it does not require a large structure, it is widely used as a simple parking facility. Proposed. These devices can be roughly classified into those operated by using the elastic force of a spring and those operated by an electric motor in terms of the driving means of the flap.

[0004]

[Problems to be solved by the device]

 First, a mechanism that uses a spring to operate the flap (Japanese Patent Publication No. Sho 49-25711, etc.) is simple and inexpensive, but it is difficult to control the operation of the flap, and the lower surface of the vehicle body and the ground surface are difficult to control. It is difficult to respond to vehicles with different distances between the vehicle and the vehicle, and there is also the possibility of damaging the vehicle body due to sudden movements of the flaps. On the other hand, in the case of a mechanism driven by a motor, the above-mentioned problems do not occur, but on the other hand, a sensor such as a torque sensor that detects the contact between the flap and the vehicle body, a control mechanism that controls the drive of the motor, etc. It is necessary, complicated, and expensive.

More recently, a device using both a motor and a spring has been proposed. For example, Japanese Patent Publication No. 54-2880 and Japanese Patent Publication No. 1-54509 are examples. Both are devices that combine the simplicity of springs with the controllability of motors, but they use multiple springs and the mechanism is relatively complex and large.The mechanism is integrated adjacent to the flap. It is assumed that it will be housed in a mechanical cabinet (fee tower) that is vertically installed.

Here, in the device in which the flap portion and the toll tower are integrated, since the vehicle stop position and the toll tower are close to each other, the vehicle comes into contact with the toll tower when entering and leaving the vehicle. Due to the possibility of accidents to be touched and the shape of the parking place where it is difficult to install it integrally with the toll tower, a device that separates the mechanism that operates the flap from the toll tower has been proposed. In this case, it is difficult to separate the flap operating mechanism from the toll tower because the mechanism is large in the above configuration.

[0007]

[Means for Solving the Problems]

 The present invention is constructed in view of the above-mentioned problems. One side of the flap is fixed to the shaft and the shaft is rotated to raise and lower the flap to lock or park the parked vehicle or leave the vehicle. More specifically, the lock-type parking device is configured to perform, and more specifically, a control mechanism for controlling rotation of the shaft is provided for the shaft, and the control mechanism is arranged so as to be substantially orthogonal to the shaft. Screw rod and a cam member that is screwed directly or indirectly to the screw rod, and the cam member uses a means for converting its own movement in the axial direction of the screw rod into rotation of the shaft. When the screw rod rotates, the cam member moves in the axial direction of the screw rod, and the movement of the cam member causes the shaft to rotate to raise and lower the flap. Is.

[0008]

When the flap is erected, the second member is moved by rotating the screw rod by the motor, and the first member is engaged with the second member in response to the movement of the second member. The members also move. The movement of the first member causes the shaft to rotate via a cam piece provided on the shaft. The flap provided on the shaft is biased by a spring in a direction in which the flap stands, so that the rotation of the cam piece operates in a direction to release the elastic force of the spring. When lowering the flap, the screw rod is reversed to retract the second member and the first member engaging with the second member, and the cam piece is rotated in the opposite direction so that the spring is attached to the flap. The flap is lowered against the force.

【Example】

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

First, the outline of the first embodiment of the present invention will be described with reference to FIG. 2 showing one of the operating states of the apparatus. In this embodiment, a flap 3 is provided on a shaft 1 supported by a bearing 2, and a cam member 4 is fixedly mounted on the shaft 1. Further, a part of a control mechanism described later is engaged with the cam member 4. The basic configuration is to do. As a result, the shaft 1 is rotated by the operation of the control mechanism via the cam member 4, and the flap 3 provided on the shaft 1 is raised or lowered by this rotating motion.

Next, details of the above configuration will be described with reference to FIG.

Both ends of the shaft 1 are supported by bearings 2. A flap 3 is fixed to the shaft 1 so that one side of the edge is located in the axial direction. Reference numeral 5 is a coil spring inserted through the shaft 1, and both ends are locked to the bottom surface of the device and the back surface of the flap 3. With this structure, the flap 3 moves toward the upright direction by the coil spring 5. Being energized. An arrow 6 indicates a control mechanism that engages with the shaft 1 via a cam member 4 fixed to the shaft 1 and controls the rotation of the shaft 1.

First, a pair of cam members 4 are attached to the shaft 1 so as to sandwich the control mechanism 6. A groove 4a is formed in the cam member 4 as shown in FIG. 2, and a pin 9 which is a part of a control mechanism described later is engaged with the groove 4a.

Next, the control mechanism 6 is composed of a mechanism body 10 and a screw rod 8 arranged so as to be orthogonal to the shaft 1. The screw rod 8 is connected via gears G1 and G2. It is configured to be driven to rotate by an electric motor M and to move the mechanism main body 10 along the screw rod 8 by the rotation of the screw rod 8. Reference numeral 7 denotes a cam driving member which is a first member of the control mechanism main body 10 and is inserted and arranged in the screw rod 8. However, the screw rod 8 is not screwed into the screw rod 8 and is movable in the axial direction of the screw rod 8 regardless of the rotation of the screw rod 8. Pins 9 and 9 project from both sides of the cam drive member 7, and the pins 9 and 9 engage with the grooves 4a of the cam members 4 and 4 located on both sides of the control mechanism 6, respectively.

On the other hand, reference numeral 11 is a main body moving member which is a second member of the control mechanism main body 10 and is screwed with the screw rod 8 and is movable in the axial direction of the screw rod 8 by rotation of the screw rod 8. It looks like this. Reference numeral 12 is a casing of the control mechanism main body 10, and the casing 12 is fixed to the main body moving member 11. On the other hand, although the cam driving member 7 is arranged in the casing 12, it is not integrated with the casing 12 and can be displaced in the casing 12 along the screw rod 8. Reference numeral 13 is a coil spring which is disposed between the cam driving member 7 and the main body moving member 11 such that the screw rod 8 is inserted in the center thereof. The cam drive member 7 is always separated from the main body moving member 11 by both the elastic force of the coil spring 13 and the elastic force of the winding spring 5 transmitted through the pin 9. Then, the side wall of the case sink 11 is pressed and locked. That is, the casing 12 has a function as a box for accommodating the internal mechanism of the mechanism body 6 and the cam drive member 7 is locked to the body moving member 11 side against the elastic force of the springs 5 and 13. It also functions as a locking means for making it. Further, 14 is a limit switch arranged between both members 7 and 11, and when the switch is turned on, a motor stop signal is issued.

Next, the operating state of the above device will be described.

When the vehicle enters, the flap 3 descends like the swing plate 51 in FIG. 6, so the vehicle C passes through the flap 3 through a cross plate similar to that shown by reference numeral 50 in FIG. Stop in place. When the vehicle enters a predetermined position and stops, a sensor (not shown) detects this and sends an operation signal to the motor M of the parking device, and the motor M rotates the screw rod 8. Due to the rotation of the screw rod 8, the main body moving member 11 screwed to the screw rod 8 moves in the X1 direction along the screw rod 8. The cam driving member 7 pressed against the side wall of the casing by the elastic force of the winding spring 5 and the coil spring 13 moves in the X1 direction while maintaining this state by the elastic force as the main body moving member 11 moves. . That is, the movement of the cam moving member 7 causes the cam member 4 to rotate in the X2 direction (see FIG. 2) via the pins 9 and 9. In this case, since the elastic force of the coil spring 5 is added to the flap 3 and is biased in the standing direction, the movement of the pin 9 in the X 1 direction gives a driving force to the standing of the flap 3. Instead, the elastic force of the coil spring 5 is gradually released by the movement of the pin 9, so that the flap 3 stands up by the elastic force of the coil spring 5.

When the tip side edge of the flap 3 comes into contact with the bottom surface C1 of the vehicle as shown in FIG. 4, the flap 3 no longer stands up, the rotation of the shaft 1 also stops, and the cam drive member 7 moves accordingly. The movement in the X1 direction is also stopped. On the other hand, since the main body moving member 11 continues to move forward by the rotation of the screw rod 8, the main body moving member 11 approaches the cam driving member 7 against the elastic force of the coil spring 13. When the main body moving member 11 comes close to a certain distance, the limit switch 14 operates to generate a motor stop signal, which stops the rotation of the screw rod 8. In this case, since the coil spring 13 acts as a damper, a force that forcibly erects the flap 3, which is in contact with the bottom edge of the vehicle body at the tip side edge, is not generated, and naturally the vehicle is damaged. There is no. Even if an attempt is made to push back the upright flap, the movement of the cam member 7 is blocked because the main body moving member 11 is stopped in the state of being screwed onto the screw rod 8, and as a result, the flap 3 does not descend. Therefore, the vehicle is locked to prevent unauthorized exit. In this case, the limit switch 14 may operate by forcibly pushing down the flap 3, but since the limit switch 14 sends only the motor stop signal, this operation causes the motor to operate and the flap not descend. Absent.

Next, when the vehicle is to be exited by inserting a predetermined fee, a control device (not shown) issues a motor operation signal. This signal causes the electric motor M to rotate in the opposite direction to that described above, causing the screw rod 8 to rotate in the reverse direction, whereby the body moving member 11 retracts in the Y1 direction. Since the cam moving member 7 is locked to the casing 12, the cam moving member 7 and the shaft 1 rotate in the Y2 direction in response to the movement of the main body moving member 11 in the Y1 direction. The flap 3 further descends in the Y3 direction (see FIG. 2), and when it reaches the lowest position, the limit switch 15 operates and the device stops. Since the lowest position of the flap 3 is always the same position, unlike the standing position, the limit switch 15 may be arranged so that it operates at the moving position of the control mechanism at the lowest flap position. Is unnecessary.

As is apparent from the drawings, the flap actuating mechanism described above can be formed to have a size slightly higher than the installation height of the pivot shaft 1 of the flap, so that the mechanism can be installed in the charge tower. It is not necessary to install it, and it is possible to separate the toll tower and the flap installation part. Further, in this case, even if the drive mechanism is installed beside the flap, the installation height of this drive mechanism may be slightly higher than the installation height of the shaft 1.

FIG. 5 shows another embodiment of the present invention.

A main body moving member 20 is screwed onto the screw rod 8, and a cam member 21 is attached to the main body moving member 20 via the damper mechanism (not shown) as described above. It has been burned. On the other hand, one end of the crankshaft 22 is provided for the shaft 1 that rotates the flap 3, and the other end is located in the groove 21 a of the cam member 21.

With this configuration, for example, when the cam member 21 moves in the X1 direction, one end of the crankshaft located in the groove 21a of the cam member 21 relatively slides along this groove and rotates in the X2 direction. , Flap 3 is erected in the X3 direction. On the contrary, when the cam member 21 is moved in the Y1 direction, one end of the crankshaft is rotated in the Y2 direction and the flap 3 is lowered in the Y3 direction.

[0024]

[Effect of device]

 As described in detail above, the present invention is configured to raise and lower the flap by the elastic force of the spring and the driving force of the motor, and the parked vehicle can be locked regardless of the vehicle height, and Since the device can be downsized, the flap operating mechanism and the toll tower can be separated, and the device can be installed under a wide range of conditions.

Further, since it is not necessary to specially install the flap locking means when the flap is erected, the mechanism can be simplified and the failure rate can be reduced, and the apparatus can be provided at low cost.
