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

The present invention relates to a swing door mechanism installed to open and close a subway gate. The swing door mechanism is one of the access control devices, which is appropriately applied to the always open method to improve the passenger handling ability, but may be applied to the always closed method. Hereinafter, "front" means the direction in which the door is closed (actuated), and "rear" means the direction in which the door is opened (return).

Frame 10 according to the present invention is installed at a predetermined interval on the gate. The frame 10 is equipped with a main component (module) to be described later, and the installation interval is set differently according to the circumstances of the history, but in order to improve the passenger handling capacity, it is required to keep the installation interval to a minimum.

According to the present invention, the outer door 30 is rotatably installed on the frame 10 via the hinge shaft 31. The outer door 30 is a tubular structure having an opening in the front and is molded of synthetic resin for the protection of the passenger. Couple the support of the steel for strength reinforcement to the rear of the outer door 30, and combines the drive plate 33 for receiving the operating force of the motor 21 to be described later on the support. The hinge shaft 31 is installed to connect the lower end of the outer door 30 and the frame 10.

At this time, the outer door 30 is rotatably connected to the motor 21 having the crankshaft 23 via the drive link 25. The motor 21 uses a servo motor and performs reciprocating rotation within a set angle range (for example, 180 °). One end of the drive link 25 is connected to the crankshaft 23 of the motor 21, and the other end thereof is connected to a bracket (not shown) located below the drive plate 33 of the outer door 30. Accordingly, the drive link 25 is pushed or pulled to open and close the outer door 30 while the motor 21 reciprocates the stroke. A related configuration is already known from Korean Patent Publication No. 663978 (December 26, 2006) by the present applicant.

In addition, according to the present invention, the inner door 40 is rotatably installed through the hinge shaft 41 inside the outer door 30. The inner door 40 is formed of a size that is concealed in the inner space of the outer door 30 as a plate material. The hinge shaft 41 is installed to allow the inner door 40 to rotate on the inner space of the outer door 30. The inner door 40 also has a suitable structure that combines the synthetic resin and the iron like the outer door (30). The inner door 40 is provided with a driven plate 43 for receiving the operating force of the motor 21 to the rear.

At this time, the inner door 40 is preferably a soft material than the outer door 30. The inner door 40 should have a weaker strength than the outer door 30 and a good cushioning (cushion) is required so that passengers entering and exiting due to sudden closure of the door are not injured.

In addition, according to the present invention, the rapid movement means 50 is connected to open and close the inner door 40 in conjunction with the opening and closing movement of the outer door (30). The rapid movement means 50 interposed between the outer door 30 and the inner door 40 maintains a rapid and quiet operation of the inner door 40 over a long period of time.

As a detailed configuration of the present invention, the rapid movement means 50 is connected to the upper link 51 and one end of the upper link 51 and the frame 10 is rotatably mounted on one side of the outer door (30). A lower link 53 and a driven link 55 for connecting the other end of the upper link 51 and the inner door 40 are provided. The upper link 51 is formed in a T-shaped structure and has an upper first acting point 51a, a lower second acting point 51b, and a center point 51c of an intersection point. The center point 51c of the upper link 51 is rotatably connected to the driving plate 33 of the outer door 30. The lower link 53 has a lower end rotatably connected to the frame 10 via the bracket 12 and the upper end rotatably connected to the second working point 51b of the upper link 51. One end of the driven link 55 is rotatably connected to the driven plate 43 of the inner door 40, and the other end is rotatably connected to the first working point 51a of the upper link 51.

At this time, the rapid movement means 50 is provided with a tension spring 64 between the frame 10 and the upper link 51, to perform the closing of the door 30, 40 with elastic return force when the power off. It is good. In the opening and closing process of the door 30, 40, the upper link 51 performs a rapid rotational movement based on the center point (51c). When the tension spring 64 is connected to one end of the upper link 51 and the frame 10 or the bracket 12, the door 30 and 40 are opened in an emergency while absorbing the impact of the operation. That is, even when the tension spring 64 is powered off after the door 30, 40 is closed, and the motor 21 does not operate, the tension spring 64 immediately maintains the door 30 and 40 in the open state by the accumulated elastic energy. Allows entry of

In addition, a damper 62 may be installed between the frame 10 and the upper link 51 so as to be adjacent to the tension spring 64. The damper 62 absorbs the impact force of the operation by using the fluid, thereby improving durability of the operating portion and mitigating noise.

On the other hand, the outer door 30 is provided with a torsion spring 66 on the hinge shaft 31, and performs the opening of the door 30, 40 with elastic return force when the power off. The torsion spring 66 has one end supported by the frame 10 and the other end supported by the side of the outer door 30, and performs the opening of the doors 30 and 40 in an emergency while absorbing the impact of the operation. That is, the torsion spring 66 opens the doors 30 and 40 with the accumulated elastic energy to allow passengers to enter or exit even after the power is turned off after the doors 30 and 40 are closed. do. Of course, mitigation of operating shocks leads to increased durability and reduced operating noise.

In FIG. 1, reference numeral 15 denotes a detector, which detects the stroke of the motor 21 according to opening and closing of the doors 30 and 40.

In operation, the driving link 25 is located at the bottom dead center in the open state of the doors 30 and 40 as shown in FIG. 7 to maintain the upper link 51 in a stopped state and control the gate. When this occurs, as shown in FIG. 8, the drive link 25 is moved to the top dead center by the operation of the motor 21 to rotate the outer door 30, and at the same time, the upper link 51 connected to the drive plate 33 is the outer door. Move forward along the 30, the upper link 51, which is constrained by the lower link 53 at the bottom, starts to rotate and pushes the driven link 55 at the top forward, and finally the inner door ( 40 is exposed from the outer door 30 to close the door 30, 40, thereby inhibiting entry and exit. After that, when the situation is finished, the motor 21 rotates in the reverse direction to return to the initial state.

While the elastic energy is accumulated in the tension spring 64 and the torsion spring 66 during the state of FIG. 7 to FIG. 8, the damper 62 performs a function of returning the doors 30 and 40 to the open position when the power is turned off. ) To buffer the operation.
