Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a traffic control door that opens a passage door by inspecting an a-air card.

[Prior Art] Conventionally, a door provided in a passageway, a locking mechanism for holding the door in a closed position, and a magnetic card detector are provided, and when a legitimate magnetic card is detected by the Hokki magnetic card detector, the above-mentioned 2. Description of the Related Art A traffic control door in which a locking mechanism is used to release the opening and closing of the door is already known.

Therefore, it is desirable to provide an inspection lid close to the locking mechanism so that maintenance and inspection of the locking mechanism can be easily performed by opening the inspection lid. If the door is opened and the lock mechanism is operated to open the door, the traffic control door becomes meaningless.

[Summary of the Invention] Therefore, in view of such circumstances, the wooden invention provides an inspection lid for the lock mechanism described in 1-1, and also provides a detector for detecting that the inspection lid is opened. The opening of the inspection lid can be monitored using a device.

[Embodiments of the Invention] The wooden invention will be explained below with reference to the illustrated embodiments.
, In Fig. 2, (1) is a passage, (2) is a pillar erected on one side of this passage, and above this pillar (2) is a passage (
1) 9 This 18 (3) has a door (3) that can be opened and closed.
) is composed of an upper plate member (4) and a frame member (5) attached to the lower part of this plate member (4). The passageway (1) can be divided and closed into an inner area A and an outer area B. The door (3) is swingably attached to the column (2) by an upper hinge (6) and a lower hinge (7) at the upper plate-like member (4). A return spring (not shown) holds the passage (1) in the closed position.

The pillar (2) is provided with a locking mechanism (8) that locks the door (3) in the closed position.
8), as shown in Figures 3 and 4, consists of a bracket (9) fixed inside the support column (2), a horizontal bottle (10) attached to this bracket, and this pin (10). It is provided with a roughly T-shaped drawer (11) mounted so as to be swingable in a vertical plane. One arm (12) of the lever (11) is connected to a solenoid (13) that swings the lever (11).
), and the other arm (14) is linked to the lock shaft (15).
It is linked to. This opening/took shaft (15) is slidably attached to the bracket (9) in several cases, and its tip protrudes from the column (5) toward the door (3), and a lock roller is attached to the protruding end. (16) is rotatably provided.

A lock member (17) is provided on the Kitagi door (3) so as to face the lock roller (16), and this lock r<++
The material (17) is provided with four parts (18) into which the lock roller (16) is inserted. The lock roller (16) is operated in four parts (only when the folding screen (3) is in the closed position).
18), and when the lock roller (16) is engaged with the recess (18), the first riser (3) is located in its closed position and cannot be opened or closed, and is locked. 1. The roller (16) is detached from the recess (18).
1 so that JjB (3) can be opened and closed in both directions at 1t.
There are 7.

Further, the lock roller (16) is connected to the lever (-1-) (
11) is biased counterclockwise in FIG. 4 to engage the recess (18) by the spring (20), and - the normal solenoid (13) is deenergized. In this state, the door (3) is maintained in the closed state by engaging the two recesses (18). 17 Therefore, it is necessary to be able to manually open the door (3) in the event of an emergency such as a fire during a power outage, and for this purpose, an operation window (21) is installed on the side of the pillar (2) on the inner area A side. The lock roller (18) is disengaged from the recess (18) by rotating the lever (11) clockwise in FIG. 4 against the spring (20) through the operation window (21). I'm trying to do that. In addition, the pillars on the B side of the queen's outer area (
2) A lid (22) for maintenance and inspection of the lock mechanism (8) is provided on the side, and maintenance and inspection of the lock mechanism (8) can be performed by opening the lid (22) for inspection. We are making it possible to do so.

However, as shown in Figures 1 and 2, detectors (25) for detecting magnetic cards are provided on both sides of the above location (3), and each detector (25) is placed in the chest pocket of a passerby. It is set at a height that allows it to detect a magnetic card even if it is inserted.

And on both sides of the pillar (2), there are traffic buttons (2G), (
27), and the detection signals from these detectors (25) and traffic buttons (26), (27) are transmitted to the pillar (
2) is inputted to a control device (28) provided at the bottom of the unit. Additionally, a detector (28) detects that the door (3) is opened from the closed position to a predetermined angle, and a detector that detects that the inspection lid (22) of the lock mechanism (8) is opened. (30), and each detector (28)
, (30) are also being input to the control device (28).

Figure 5 shows an electrical circuit diagram, in which (
31R), (32R), (33R),' (
34R') and (35R) are relays, (31R-
1), (31R-2), (31R-3), (3
2R-1), (32R-2), (32R-3)
, (33R-1), (33R-2) are normally closed contacts, (
31R-4), (32R-4), and (34R-1) are normally closed contacts, (36T) is a timer, (36T-1) is a normally closed contact of the timer (38T), and (37) is a counter.

In the above configuration, in the normal non-operating state, the door (3) is closed and held in position by the locking mechanism (8), and when the pass button (26) is pressed from the outside of the door (3), for example. When the relay (31R) is energized, the normally open contact (31R-1) closes and is self-maintained. In this state, the magnetic card is detected by the detector (25), and if the magnetic card is a legitimate one, the relay (33R) is energized, and the normally open contact (33R-1) is closed and self-held. And each relay (31R), (33R) is
Normally open contacts (31R-3) and (3
When 3R-2) is closed, the solenoid 13) is energized,
The lock roller (16) separates from the recess (18) and the door (
The closed state of 3) is released.

In this state, passersby can pass by pushing the door (3) to open it in the direction of travel. When the door (3) is opened by a predetermined amount or more, the detector (29) detects this, energizes the relay (34R), and at the same time causes the counter (37) to count the number of openings and closings, that is, the number of passersby. When the relay (34R) is energized, the normally closed contact (34R-1) opens, so the above relay (31R),
(331?) is set to 1 position, which causes the solenoid (
13) is also deactivated. When the solenoid (13) is deenergized, the lock roller (16) is projected by the elastic force of the spring (2o), but at this time, since m(3) is open, the lock roller (16) cannot engage with the recess (18), and the opening/shifting member (17) north will roll in response to opening and closing of the door (3). When a passerby passes by and the door (3) returns to the closed position by the return spring, the lock roller (1B) engages with the fourth part (18), so the door (3) closes. It will be held in position.

Furthermore, when the Hokki Pass button (26) is pressed, the normally open contact (31R-2) of the relay (31R) closes at the same time, so the timer (3flT) starts operating, and the 1-Pass Pass button ( 26) If the door (3) is not opened even after a predetermined period of time has passed since the button was pressed, the timer (3) will not open.
6T) opens the normally closed contact (36T-1). This restores the original non-operating state and prevents the location (3) from being left open.

It is clear that the above explanation is the same even when the passage button (27) inside the door (3) is pressed.

As mentioned above, when it is necessary to manually open the door (3) in the event of a fire or other emergency during a power outage, the lever (11) can be moved from the operation window (21) using the spring (20). If you rotate it clockwise in Figure 4 against the
6) and the recess (18) can be disengaged.
Door (3) can be opened.

Also, when the inspection lid (22) is opened for maintenance or inspection of the lock mechanism (8), the detector (30
) detects this, listens to the relay (35R), and notifies the control room (not shown) that the inspection cover (22) has been opened. It will be possible to monitor opening and closing.

[Threat 2 Ming IJ+Result] As mentioned above, the present invention is provided with an inspection tool body for the locking mechanism, so that the maintenance and inspection of the lever/pull mechanism can be easily performed. A detector is installed to detect when the inspection lid has been opened, so this detector monitors the opening of the inspection lid to prevent unauthorized persons from entering the interior. 11-You can get the effect of being able to dry.
