Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a door drive mechanism for an automatic ticket gate equipped with a locking function.

Conventional ticket gates that lock the door when the passageway is closed have a locking mechanism using a solenoid mechanism in addition to the door drive mechanism, so a control circuit for the locking mechanism is required. Moreover, both must be controlled in synchronization, which has the disadvantage of making the device complicated and expensive.

The present invention provides a door drive mechanism for an automatic ticket gate that can automatically lock and unlock the door simply by rotating a rotating shaft for driving the door, and can also securely lock the door. The purpose is to

Hereinafter, the embodiment shown in the drawings will be described. Reference numeral 1 denotes a main body of a political ticket machine, and a door 2 is rotatably attached to one end of the main body on the aisle side.

Reference numeral 3 denotes a main body arm whose one end is fixed to the shaft 4, and 5 is a main body arm whose one end is rotatably attached to the door 2 at a mounting portion 6.

The arms 3 and 5 are connected so as to be bendable about the connecting portion 7, and are configured to be bent greatly on one side and slightly bent on the other side.

In other words, the line connecting the shaft 4, the connecting part 7, and the mounting part 6 bends greatly when the arm is bent, with the connecting part 7 as the center, but when the arm is extended, the end walls 3a and 5a of each arm bend in the same direction. It is constructed so that it bends slightly in the opposite direction. The shaft 4 is rotatably supported by the main body 1 and connected to a rotation source such as a motor.

Reference numeral 8 denotes a tension coil spring provided between the arms 3 and 5, and is installed so that its position is on the opposite side to the connecting portion 7 when the arms 3 and 5 are bent and extended.

In this example, the connecting portion 7 and the tension coil spring 8 are provided on opposite sides with respect to the imaginary line connecting the shaft 4 and the attachment portion 6 when the arm is extended. In this device, when the passage is open, the arms 3,
5 is bent around a connecting portion 7, and the door 2 is positioned along the wall surface of the main body 1 on the passage side.

When the shaft 4 is rotated in the direction of arrow A in this state, the arm 3 is rotated in the same direction, so the arms 3 and 5 are extended against the force of the tension coil spring 8, and the door 2 is thereby shaped into a fan shape. will be moved to At this time, the tension coil spring 8 approaches the connecting part 7 as the arms 3 and 5 extend, and when it is located on the opposite side beyond the connecting part 7, it acts to bend both arms in the opposite direction, and the connecting part 7 further in the direction of movement when the arm is extended. Therefore, the tension coil spring 8 and the connecting portion 7
After the position of arm 3 is reversed, arm 3 is immediately bent in the opposite direction, and even if the rotation source is stopped immediately, arm 3
, 5 are not bent back to their original state. In addition, when the arms 3 and 5 are extended, the connecting portion 7 is biased by the tension coil spring 8 with a moving force in the direction opposite to the direction of movement when the arms are extended, that is, the direction of movement when the arms are bent. Therefore, as shown by the two-dot chain line, the arms 3 and 5 are not bent any further because their end walls 3a and 5a are in contact with each other, and the door 2 is moved to the position shown by the two-dot chain line. It is closed due to

Therefore, in this state, even if the door 2 is pushed in the direction of arrow B, the arm 2 will not bend any further, so the door 2 is locked in a state where the passage is closed. Next, when the shaft 4 is rotated in the opposite direction with the arms 3 and 5 extended, the arms 3 are rotated in the same direction, and the arms 3 and 5 are centered around the connecting part 7, as shown by the solid line. The door 2 is then moved to its original position and the passage is opened.

In this case, when the tension coil spring 8 crosses the connecting part 7,
Since the tension coil spring 8 acts to bend the arms 3 and 5, the time for opening the passage by moving the door 2 quickly is shortened, and even if the rotation source is stopped, the arms 3 and 5 are bent.
, 5 are bent by the force of the tension coil spring 8 to open the door 2.
is moved. As described above, in the present invention, when the arm is extended, the intermediate fulcrum is located between the fulcrum of the main body side arm and the fulcrum of the door side arm, and each fulcrum is located at each vertex of the triangle. , and the stopper prevents the arm from bending in the opposite direction to the direction in which the intermediate fulcrum moves across the straight line connecting the fulcrum of the main body side arm and the fulcrum of the door side arm. Since the intermediate fulcrum is biased in the opposite direction to the moving direction of the intermediate fulcrum, and the fulcrum of the arm on the main body side is used as the rotation axis for driving the door, the arm can be bent and extended simply by rotating the rotation axis. The door can be moved, locked, and unlocked using the arm, which has the effect of simplifying the device. There is no risk of bending and the lock can be reliably locked.

Further, in the present invention, when the arm is extended, the intermediate fulcrum is moved in the opposite direction to the direction of movement of the intermediate fulcrum when the arm is bent.
Since the arm is provided with a spring that biases the fulcrum and biases the intermediate fulcrum in the opposite direction when the arm is bent, the driving source is immediately activated after the biasing means has passed the intermediate fulcrum. Even if the arm stops, the arm does not bend or extend back to its original state, but continues to extend or bend under the force of the biasing means.
