3 is an operational state diagram showing a door (D) holding function of the ship door holder (H) according to an embodiment of the present invention.

Referring to FIG. 3, the ship door holder H holds the door D in an open state by magnetic coupling of the magnet 100 and the holding device 200. That is, when the door D is open, the push plate 231 formed of a magnetic material is magnetically coupled to the magnet 100 mounted on the door D to hold the door D in the open state. Therefore, the ship door holder (H) according to an embodiment of the present invention can hold the door (D) in the open state without a separate power supply. In addition, by holding the door (D) installed on the emergency passage in the open state, it is possible to easily secure the escape route of the crew in the event of an emergency, such as a fire, thereby causing human life Therefore, physical damage can be minimized.

4 and 5 is an operating state diagram showing the hold release function of the ship door holder (H) according to an embodiment of the present invention.

First, referring to FIG. 4, in the state in which the door D is held in the open state, the user applies an external force to the door D in the P direction. That is, the user pushes the door D toward the wall surface W (see FIG. 1). At this time, by the external force of the user, the push unit 230 is slid to the inside of the body portion 220 by a predetermined degree.

As the push unit 230 slides to a predetermined degree, the first connection terminal 240 provided at one end of the push unit 230 contacts the second connection terminal 250.

Generates.

In this case, the solenoid 210 induces the same polarity as the magnet 100 mounted to the door D on the push plate 231. That is, when the magnet 100 mounted to the door D has the N pole, the solenoid 210 guides the N pole to the push plate 231, and the magnet 100 mounted to the door D is located. When the S pole is held, the solenoid 210 induces the S pole to the push plate 231. In this case, the polarity induced by the solenoid 210 may be adjusted through the direction of the current supplied to the solenoid 210.

On the other hand, referring to Figure 5, when the user removes the external force applied to the door (D), the door (D) is released by the magnetic force generated by the solenoid 210. That is, as the solenoid 210 induces the same polarity as the magnet 100 on the push plate 231, the push plate 231 pushes the magnet 100 to some extent, and thus, the door D It is rotated to a predetermined degree in the closing direction.

At this time, the push unit 230 is returned to the initial position (ie, the state in which the first and second connection terminals 240 and 250 are short-circuited) by the restoring unit 280, but the first connection terminal having the torsion spring type. The current flows through the solenoid 210 for a predetermined time by the 240. Therefore, even when the external force is removed, the current flows through the solenoid 210 to release the door D for a predetermined time.

On the other hand, due to the magnetic force of the solenoid 210, the door (D) pushed out of the push plate 231 by a predetermined degree is closed by the door closer (C, see FIG. 1), etc., the push unit 230 is the restoring unit 280 Is returned to the initial position, and the first and second connection terminals 240 and 250 are short-circuited.

As described above, the ship door holder (H) according to an embodiment of the present invention can easily release the door (D) without a separate switch. That is, when the user pushes the door D held in the open state to the wall surface W direction, the door D is released by the sliding movement of the push unit 230 and the magnetic force of the solenoid 210. . Therefore, it is very easy to operate, and it does not need a separate switch, so it looks good.

In addition, since the power supply unit 260 temporarily supplies current only during the hold release operation of the door D, unnecessary power waste can be minimized, and the power supply unit 260 is frequently replaced due to power consumption of the power supply unit 260. And troublesome maintenance.

On the other hand, the ship door holder (H) according to an embodiment of the present invention can be remotely controlled in the steering room and the like through the central power line (270). That is, it can be controlled simply by supplying the current to the solenoid 210, it is possible to remote control by connecting only a simple current supply line. Therefore, even when it is necessary to release the door D for the purpose of forming a firewall or the like in the event of a fire, there is a technical advantage that remote control is possible in the steering room or the like.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, many modifications and changes may be made by those skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims. The present invention can be variously modified and changed by those skilled in the art, and it is also within the scope of the present invention.
