Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door device particularly suitable for a door portion of an automatic ticket gate installed in a transportation facility, a pay facility, or a facility in which only a specific person is allowed to enter.

[0002]

2. Description of the Related Art An automatic ticket gate is a device for permitting a passerby only to passersby who meet certain conditions, and the judgment is made through checking means such as inserting a specific ticket or inputting a password. It is a device that allows only passers to pass.
When permitting or not permitting the passage, not only sounding an alarm but also closing the passage with a door to physically make the passage impossible, or to simply pass the tip of a person trying to pass. By controlling the traffic, it conveys to the passers- ers that they refuse to pass. Also,
For example, facilities that are forbidden to enter the audience during preparation,
At the station before the first train of the day arrives, the aisles will be completely closed, and people other than staff and staff will not come and go.

Further, particularly in the case of a form in which passers-by in each passage are restricted by a plurality of automatic ticket gates, in general, a monitoring board is provided in a staff room to comprehensively control whether or not each passage can be used and the direction of passage. I am able to do it.

[0004]

However, the conventional automatic ticket gate has the following problems. If the automatic ticket gate completely restricts the passage of people, there is a risk that the evacuated customers and staff will be restrained as a dangerous obstacle during evacuation in the event of a disaster. Also, in this case, if electricity can be supplied, all the passages will be opened by control from the control panel, but in the event of a disaster, etc., the supply of power is not always guaranteed. If it cannot be opened manually, it may hinder the evacuation of evacuees promptly, resulting in a serious disaster.

The present invention solves such a problem, and even when a command cannot be issued by the supply of power to open the passage, the passage can be opened by a simple operation and a disaster occurs. Also aims to provide a safe automatic ticket gate.

[0006]

The present invention is configured as follows to solve the above-mentioned problems. That is, in a door device that drives and controls a door that rotates vertically about a door support shaft by a rotation drive means to form a passage open state and a passage closed state, in cooperation with the rotation of the door, the door device A door element that rotates around a support shaft and has a recess, and a locking arm that is normally biased in a direction away from the door element and that abuts against the recess by an external force to restrict swinging of the door, First pushing means for pushing the locking arm from the outside to move it to a position for restraining the door element, and normally biased to a position for holding the locking arm in contact with the door element. And a second pushing means for releasing a state of engagement with the locking arm by generating a couple in the retainer plate. Also,
The retainer plate is characterized in that the engaged state is released also by the direct drive power source. Further, the retainer plate is configured so that a couple can be generated by a direct-acting power source, and electric power is supplied to the direct-acting power source prior to turning on the power supply to the rotary drive means. I am trying.

[0007]

According to the present invention, when the attendant manually keeps the passage closed, when the attendant holds the door closed and presses the lock bar, the locking arm causes the door element 3 to engage. To meet. In this state, the retainer plate rotates in the biasing direction to restrain the locking arm, so that the door can be kept closed by a very simple operation.

The operation in this case can be performed with the door device turned off or on. By this operation, the passage can be kept closed even when the power of the device is turned off.

Further, when the staff manually releases the closed state as described above, if the release bar is pressed without touching the door, a couple force is generated in the retainer plate. As a result, the engagement state between the locking arm and the retainer plate is released, and the locking arm is released and separated in its biasing direction. As a result, the door element is released from the restraint, and the door can be freely swung so that the passage of the door is free.

Further, when the closed state is released by turning on the power without manual operation, a couple force is generated in the retainer plate as in the case of pressing by the release lever by driving the linear power source, and the door The locked state is released.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The drawings all show embodiments according to the present invention.
FIG. 3 is a diagram showing an installed state of the automatic ticket gate. 101 and 102 are housings, and a door 1 is provided on either or both of them.
Is provided. FIG. 1 shows the main part of the drive device for the door 1, and FIG. 2 shows the door lock state.

The door 1 shown by an imaginary line moves from an open state to a closed state or the opposite position by rotating the door shaft 11 by a door motor (rotational drive source) not shown.
As the door motor, a so-called excitation actuation type motor with a brake, that is, a type in which the armature is attracted when a voltage is applied to the excitation coil and a braking force acts on the rotating shaft is desirable. 2 is a door device base. Reference numeral 3 is a door element, and a door opening spring (not shown) is suspended on this portion, so that the door is always biased in the opening direction. Further, the door element 3 has a recess 23 as shown in FIG.
The door-side protruding end engaging portion 34 of the locking arm 4 described later
Mate with. The rocking arm 4 is rotatably fixed by a rocking arm shaft 24, and is biased in a direction away from the door element 3 by a rocking arm spring 14, and the door-side protruding end engaging portion 34 is provided on the door element 3 side. Further, the inner protruding end engaging portion 44 is provided on the retainer plate side described later. It is desirable to mount bearings or provide corners at the corners so that the protruding end engaging portions can easily slide when coming into contact with other portions.

Reference numeral 5 denotes a lock bar which is a first pushing means, and has a function of moving the locking arm 4 in a direction to be fitted into the recess 23 of the door element 3 by pushing one end of the lock bar from the outside by hand. The lock bar 5 is urged by the lock bar spring 15 so as to always protrude outside the housing 101, and is fixed to the door device base 2 by the bushing 25 so as to be slidable in the axial direction. Reference numeral 6 denotes a retainer plate, which is rotatably fixed by a retainer shaft 26 and urged by a retainer spring 16 in a direction to engage with the locking arm 4. As shown in FIGS. 1 and 2, the retainer plate 6 is formed with an arc in the portion near the door and is normally prevented from rotating by the inner protruding end engaging portion 44 of the locking arm 4.

Reference numeral 7 is a release bar which is a second pushing means.
Retainer spring 16 acting on retainer plate 6
A couple force is generated in a direction opposite to the biasing direction of the locking arm 4 to allow the locking arm 4 to move by the locking arm spring 14. Similar to the lock bar 5, the release bar 7 is biased by the release spring 17 so as to always project out of the housing 101, and is fixed to the door device base 2 by the bushing 27 so as to be slidable in the axial direction.
A release solenoid (direct drive source) 8 acts on the retainer plate 6 via a link 9 to generate a couple force in the direction opposite to the biasing direction of the retainer spring 16 like the release bar 7. , Plays a role of permitting the movement of the locking arm 4 by the locking arm spring 14.

Next, the function of the above embodiment will be described. First, in a normally used state, the door 1 is driven by a door motor (not shown) via the door shaft 11. In this case, the passage closed state is a state where the housing 101 and the door 1 are orthogonal to each other, and the passage opened state is the housing 1
01 and the door 1 are in parallel. When the door reaches each position, the sensor detects the door position, the application of voltage to the door motor itself is stopped, and the built-in brake is attracted to hold the door 1 in the open state or the closed state. . On the contrary, when the power supply to the door motor is completely cut off, the door opening spring (not shown) biases the door element 3 in the clockwise direction in the embodiment shown in FIG. Also, a rotational force is generated in the counterclockwise direction, and it abuts against the housing 101 and stands still while the passage is open. When the power to the door motor is cut off, the door is free to move because the brake is not acting on the door shaft 11.

The procedure and operation for locking the door 1 in the closed state will now be described with reference to FIG. 1. First, the door in the free state is manually moved to the closed position. In this state, when the lock bar 5 is pushed from the outside, the locking arm 4 rotates in the direction of arrow A against the locking arm spring 14, and the door-side protruding end engaging portion 34 of the locking arm 4 rotates.
It fits in the recess 23. The retainer plate 6 that has been restrained by the displacement of the locking arm 4 is opened, and is rotated in the direction of arrow B by the biasing force of the retainer spring 16. As a result, the locking arm 4 is, on the contrary, held by the retainer plate 6, and as a result, the door 1 is restrained via the door element 3 and the locking arm 4 (state of FIG. 2).

Next, when manually releasing the restrained state, the following procedures and operations are performed. When an operator such as a staff member pushes the release bar 7, the tip of the release bar 7 is in contact with the retainer plate 6 and a couple force in the direction of arrow C acts on the retainer plate 6 against the retainer spring 16. As a result, the retainer plate 6 moves, the constraint of the locking arm 4 is released, and the locking arm spring 14 moves in the direction of arrow D by the urging force of the locking arm spring 14. Therefore, the fitted state between the door-side protruding end engaging portion 34 of the locking arm 4 and the recess 23 of the door element 3 is also released, and the door 1 is opened by the urging force of the door opening spring (not shown).

Further, the release solenoid 8 opens the door 1 in the locked state by electrical control. The release solenoid 8 is connected to the retainer plate 6 via a link 9 when the pull type is used as shown in FIG. By energizing the coil of the release solenoid 8 in this state, a couple of force is generated in the retainer plate 6 in the direction of arrow C, and the locking arm 4 is opened, and the locking arm 4 is opened. The restraint will be released. The operation of the release solenoid is performed so that it is always performed when the device is powered on, that is, as one of the initial resets.

[0019]

EFFECT OF THE INVENTION The present invention has the following effects by having the above-mentioned constitution and function. First, the lock operation and the release operation can be performed extremely easily with one touch by the first and second pushing means. Further, unlocking when the direct drive source (release solenoid) is provided can be performed by remote operation. Further, as a so-called initial reset process, the control part is configured by software so that power is supplied to the linear drive source (release solenoid) prior to turning on the power to the rotary drive source (door motor). Therefore, it is possible to prevent the device from being broken due to an excessive force applied to the locked door. Further, the door mechanism has a simple structure and is inexpensive.
