A DOOR OPENNING DEVICE FOR AUTOMATIC DOOR AT EMERGENCY}
[31] The present invention relates to an automatic door system having both a sliding method of sliding and opening and a sliding type of opening and closing in a rotational form, in particular, the automatic door sliding direction by the restoring force of the elastic member when power is not supplied in an emergency such as power failure or fire. It relates to an automatic door opening device in case of emergency for opening at regular intervals. The present invention also relates to an automatic door system in which an automatic door opening device is installed in an emergency.
[32] Conventional sliding automatic doors are embarrassed when the door is pushed in the sliding direction and escapes from the room when the power is not supplied in an emergency state when the door is closed, or when the door is broken and tries to escape by sliding the door in the sliding direction. There was a problem that takes a long time.
[33] In order to solve this problem, there is an improved sliding and sliding automatic door that can be opened by sliding automatic door. Korean Patent Application No. 10-1998-8858 discloses a technique for a sliding door and a sliding type automatic door. Fig. 7 is a perspective view showing the principle of the opening and closing type automatic door described in the above document. When the sliding and sliding automatic door 13 receives an open signal in a state where power is supplied, the motor 15 installed in the drive control unit frame P operates to rotate the pulley 16 and is restrained by the pulley 16. The timing belt 17 is moved. Since the hanger 18 is connected to the timing belt 17, the hanger 18 is supported by the roller 19 installed to enable the cloud movement on the guide rail to move in conjunction. The door 13 is coupled to the door lower frame 20, the door lower frame 20 is rotatably coupled to the upper door frame 21 at one end, and the upper door frame 21 is coupled to the hanger. It is. Therefore, the rotational movement of the motor 15 is converted to the linear movement of the door 13 to automatically open and close the door, and in case of an emergency, the upper frame 20 and the lower door 20 of the door are rotated and separated. (13) can be opened and closed also by the opening and closing method.
[34] The sliding and sliding type automatic doors are generally used in combination with a security guard system. As shown in Fig. 5, the automatic door system receives an accessor's unique identifier fee such as a password and a card key from an accessor, and separately installs an accessor identification input device (A) for selectively accessing the accessor. It is common to use in conjunction with.
[35] However, the sliding and sliding type automatic door 13 has a problem that the automatic door cannot be evacuated quickly because it is mistaken that the automatic door is closed in case of an emergency when no power is supplied, and the user tries to evacuate in an embarrassing state. There is also a fear that the evacuator will mistake the automatic door for closing and return to find another exit without attempting to push the door open. Therefore, it is desirable to leave the door open at regular intervals in case of an emergency and mark it as easy to open by pushing the door by hand. An object of the present invention is to provide a device that can be opened at regular intervals without providing automatic door movement force of the automatic door system in a state where power is not supplied.
[36] Moreover, even if the security system is installed in combination with an automatic door, a thin paper or other object is inserted into the gap between the door and the door frame to generate a signal such as a person coming from the inside of the door to prevent the automatic door from opening by itself. For example, an automatic door system has been used in which a groove is formed in a part facing the door of the door frame so that a part of the door enters and is installed inside the door frame. In this case, the conventional sliding and sliding automatic door system as shown in Fig. 7 has a problem that a part of the automatic door enters the groove of the door frame, so that it cannot be opened at once by the opening and closing method in an emergency. In other words, if you want to open the automatic door in the case of opening and closing, the automatic door is opened by sliding at a certain interval, and then the automatic door is opened by sliding in the direction of opening and closing. Therefore, a person who is in a state of embarrassment in an emergency such as a fire may take a long time to evacuate and may not escape the danger promptly.
[37] Therefore, in the automatic door system having a groove formed in the door frame for the purpose of security, the automatic door is automatically opened at a certain interval in the event of no power supply, indicating that the automatic door is open and opening and closing the door at once. The device is particularly desired.
[38] It is also an object of the present invention to provide an automatic door system having an automatic door opening device.
