Description

  The present invention relates to an automatic door opening and closing device, and more particularly, to an automatic door for entrance management installed at the entrance of an apartment house such as a condominium, which is provided with an opening and closing control means for preventing illegal entry from the outside. Relates to the device.

In general, automatic doors for entrance management in apartment houses are arranged with internal and external sensors that detect objects (human bodies) on the indoor side and outdoor side of the doors, respectively, and the doors are opened and closed by means of detection signals from these internal and external sensors. Is opened and closed.
Specifically, normally, when the outside sensor or the inside sensor detects a person entering / exiting, the opening / closing control means outputs an activation signal to open the door so as to enter / exit. And at the designated time zone set by the timer such as at night, it is set to disable the output of the start signal even when only the outside sensor is detected with the door closed, in which case the resident The outside sensor is temporarily enabled by operating a key switch or PIN button switch, etc., and the visitor enters the room through the intercom, and the outside sensor is activated by the resident's entry permission operation (button operation). The room is entered when it is temporarily enabled.

However, since the inner sensor is effective during the specified time period when the start signal output by the outer sensor is disabled, a detected object such as a newspaper, flyer or long object is inserted from the door and sash or unseen gap from outside. Intrusions that cause the doors to open by causing the inner sensor to detect them frequently occur. Several prevention plans have been proposed to prevent the illegal intrusion.
For example, using Patent Document 1 (Japanese Patent Publication No. 40-9905), which is a one-way opening / closing method by arranging two sensors, a door is detected when the inner sensor detects an object while the outer sensor detects an object. Patent Document 2 (Japanese Patent Laid-Open No. 10-61319) prohibiting the opening operation of the image sensor, two near and far detection areas are configured as the inner sensor, and whether the object is detected in the inner sensor area, illegal intrusion or indoor Patent Document 3 (Japanese Patent Application Laid-Open No. 11-311060), Patent Document 4 (Japanese Patent Application Laid-Open No. 2003-293654), and the like for determining whether the person has left the city.

Japanese Examined Patent Publication No. 40-9905 (see left column on page 3) JP-A-10-61319 (refer to claim 1) Japanese Patent Laid-Open No. 11-311060 JP 2003-293654 A

  However, in Patent Document 2, if a person stands in the detection area of the outer sensor or a baggage is left, the door cannot be opened even if a person who has left is detected by the inner sensor. is there. Further, as in Patent Document 3 and Patent Document 4, even if the inner sensor is constituted by two detection areas, the detection areas are arranged in a vertical plane extending in the same direction only by being separated from each other. Therefore, there is a possibility that the inner sensor for opening the door may be activated by inserting a long object etc. from the gap around the door, or moving them with a time difference, and depending on the approach route to the door of the exit person This may cause malfunctions such as the door opening inner sensor becoming inoperable, and there is a problem that it is not possible to secure certainty for preventing illegal intrusion, and the door opening operation cannot be ensured when the exit person leaves.

  In view of the above-described conventional circumstances, the present invention combines the operation switch disposed on the indoor surface of the door in addition to the internal sensor to prevent illegal intrusion and to ensure the safety and safety of the door opening operation when leaving. It aims at improving the property.

The present invention has a door that opens and closes by an opening / closing control means, an inside / outside sensor arranged on the indoor side and the outside side of the door, and an operation switch arranged on the indoor surface of the door, and the inside sensor Or an automatic door opening and closing device that opens a door by outputting an activation signal when an outside sensor detects an object, wherein the opening and closing control means disables the output of the activation signal by the outside sensor. When both the outer sensor and the inner sensor detect an object, the door opening operation is prohibited, the door is opened by the detection operation of the inner sensor and the operation switch , and the outer sensor if not detected an object is to the door by any of the detection operation of the internal sensor or the operation switch so as to opening motion, further, the operation switch is a touch switch this The constitution (claim 1).
According to this configuration, in the predetermined time zone in which the output of the start signal by the outside sensor is disabled in the door closed state, the door does not open of course even if a person stands on the outdoor side of the door. Even when the sensing object is inserted from the peripheral gap and is detected by the inner sensor, the door is not opened and the door closed state is maintained. When the person leaving the room leaves the room, if there is no person or baggage on the outdoor side, the door is opened as usual when the person is detected by the internal sensor or touch switch. Even if the door is standing or the baggage is left, the door will not open if it is detected by the inner sensor. However, if the exit moves forward and the touch switch of the door is turned on, the door will open. So you can leave without problems.

Further, the switching control means, in a state open door including when the door is in a state opened by the detection operation of said sensor and the touch switch, and characterized in that to effectively hold the detection operation of the inner and outer sensors and touch switch (Claim 2).
Thereby, even if the exit person stops near the opened door and the door closes in the meantime, it is detected by the outer sensor or detected by the inner sensor, or by turning ON the touch switch again, The opening / closing control means can output a door activation signal to reverse (open) the door.

The inside / outside sensor may be any of a reflection type, pyroelectric type light sensor, heat ray sensor, etc., as long as it can detect an object (human body) within a predetermined range near the indoor side or the outdoor side of the door. good, preferably typically use light sensors or ultrasonic sensors, such as infrared reflection type are popular, the operation switch may use the touch switch is a contact method that the detection operation by artificially contacting the hand To do.

According to the present invention, in a predetermined time zone such as at night, a person who attempts illegal intrusion does not open the door only by inserting a detection object from a gap around the door and causing the inner sensor to detect the detection, and the detection area of the inner sensor Since it is not easy to cause both the touch sensor on the door surface having the detection area on the horizontal plane orthogonal to the above and the inner sensor to detect the detection object at the same time, it is possible to improve the certainty of preventing intrusion.
In addition, when there are people who have left the house, even if people are standing outdoors or luggage is left unattended, the person who leaves the door approaches the door and turns on the touch switch . Since the door can be opened and exited simply by performing an exit operation from the door provided with the touch switch , there is little malfunction during the exit and the reliability can be improved.
Moreover, when exiting in that case, even if the door starts to close once, the exit person is detected by the outside sensor, or the door is inverted by the detection of the inside sensor or the ON operation of the touch switch , thus ensuring safety when leaving the door. Can do.

In addition, since reflective light sensors such as infrared rays are used for the inside and outside sensors and a touch switch is used for the operation switch, the cost can be reduced due to the versatility. Since an artificial operation is required, it is possible to provide an automatic door opening and closing device that can further ensure the certainty of preventing trespassing by combining with a reflective sensor.

The embodiment of the present invention will be described with reference to the drawings. FIG. 1 is an outline of an automatic door A installed at the entrance of an apartment house, and illustrates a case of a draw system.
1A is a front view of the automatic door A viewed from the indoor side of the entrance door, and FIG. 1B is a side view viewed from the side of the door. In FIG. A gate-shaped entrance / exit frame is formed by arranging a seamless frame 2 at the upper portion thereof, and doors 3 and 3 are installed at the opening of the frame so as to be openable and closable.
In the plain 2, there is provided a driving means 4 including a motor M as a door engine and a driving pulley 6, a driven pulley 6 a, a transmission belt 7, etc. linked thereto, and a controller (opening / closing control means) 5. The controller 5 is a known automatic door structure in which the driving means 4 is controlled to open and close the doors 3 and 3.

  In the above-mentioned intangible 2, the sensors are arranged at the inner and outer central portions, that is, the inner sensor 11 is arranged on the indoor side and the outer sensor 12 is arranged on the outdoor side (see FIG. 1B), and the door 3 , 3 is provided with a touch switch (operation switch) 13 only on the indoor surface, and an auxiliary light composed of a light projecting unit 8a and a light receiving unit 8b constituting a well-known photoelectric sensor as a means of safety measures in the entrance / exit frame. A sensor 8 is attached. In addition, although an electric lock etc. which are not shown in figure are attached to others, they are abbreviate | omitted.

The inside / outside sensors 11 and 12 exemplify a case where a reflective infrared sensor is used. Normally, the inside / outside sensors 11 and 12 and the touch switch 13 are provided with the doors 3 and 3 when they are detected (ON). The auxiliary light sensor 8 is an activation sensor that is opened. The auxiliary light sensor 8 is a sensor that is reversed and fully opened when an object is detected during the closing operation of the doors 3 and 3.
The internal / external sensors 11 and 12, the touch switch 13, and the auxiliary light sensor 8 are electrically connected to the controller 5 as shown in FIG. 2, and the motor M of the driving means 4 is activated through the controller 5 in a timely manner. Open 3 and 3.
The controller 5 receives and processes detection signals output from the internal and external sensors 11 and 12, the touch switch 13, and the auxiliary light sensor 8, and transmission signals from other accessory devices (sensors and limit switches). And a control unit 5b for controlling the operation of the entire automatic door system by a signal from the signal processing unit 5a, and a motor drive unit 5c which is a drive circuit for the motor M of the drive means 4, and is output from the sensors and switches. In response to the detection signal, the driving unit 4 is started and stopped via the motor driving unit 5c.

Operation settings and functions of the inner and outer sensors 11 and 12 and the touch switch 13 in the above configuration will be described.
In the normal time, that is, in the time zone other than the designated time zone (security time zone) set at night or the like, all of the inside / outside sensors 11 and 12 and the touch switch 13 are set in an effective state. Specifically, when detection signals output from the internal and external sensors 11 and 12 and the touch switch 13 are input to the signal processing unit 5a of the controller 5, the control unit 5b outputs a start signal to the motor driving unit 5c each time. . Therefore, if there is a person who enters the room from outside, when the person is detected by the outside sensor 11, the doors 3 and 3 are opened to enter the room, and a person who has left the room is detected by the inside sensor 12, or If the touch switch 13 is pressed and turned on, the doors 3 and 3 are opened, so that the user can exit. That is, the automatic door A normally performs a general opening / closing operation.

  Next, in a security time zone such as at night, even if the outer sensor 11 outputs a detection signal to the signal processing unit 5a of the controller 5, no activation signal is output from the control unit 5b. This is the entrance management state set so that the start signal output by is invalid. The operation control in this room entry management state will be described with reference to the flowchart of FIG.

During this time period, the controller 5 monitors whether the doors 3 and 3 are closed (SP1). When the door is closed, the controller 5 is in a detection state (ON-OFF), that is, a person outdoors. It is monitored whether or not there is (SP2).
When a person is outdoors and the outer sensor 12 is turned ON and a detection signal is output, the detection state (ON-OFF) of the inner sensor 11 is confirmed (SP3). If the inner sensor 11 is OFF, an object is detected. As a matter of course, the doors 3 and 3 remain closed without opening (SP4). On the other hand, even if the inner sensor 11 is turned ON and a detection signal is output, the door does not open by itself, but the detection state (ON-OFF) of the touch switch 13 is confirmed (SP5), and the touch switch 13 is OFF. If so, the doors 3 and 3 remain closed without opening (SP4), and when the touch switch 13 is turned on, the doors 3 and 3 finally open (SP6).

That is, the inner sensor 11 and the touch switch 13 are set to open the door with the AND condition of their detection signals. When a person is detected by the outer sensor 12, the door is opened only by turning on the inner sensor 11. Does not open. Thereby, even if a detection object such as a leaflet or a long object is inserted from the outside through a gap around the door, the door does not open, so that illegal entry can be prevented.
When the outside sensor 12 is on and there is a person who has left the room, the inside sensor 11 detects the person who has left the door 3 or 3 (SP3). By pressing 13 and performing an ON operation (SP5), the door is opened (SP6), so that it is possible to leave as it is.

In SP2, when the outer sensor 12 is OFF (no person or baggage outdoors), either the inner sensor 11 is turned on (SP7) or the touch switch 13 is turned on (SP8). Even in this case, since the doors 3 and 3 are opened (SP6), there is no problem for the exit person to leave.
Further, in SP1, when the doors 3 and 3 are in the open state, the auxiliary light sensor 8 is set to enable all the sensors including the inside / outside sensors 11 and 12 and the touch switch 13 (SP9). For example, even when an exit person tries to return to the indoors immediately after going out outdoors, the door that has been closed is opened again when the exit sensor is detected by the outer sensor 12, so that it is safe. At the same time, it is not necessary to use a security device or to enter a room.

  In the security time zone, when a resident or a visitor enters a room, it is the same as before. That is, using a security input device installed outdoors, the resident enters the room with the outside sensor 12 temporarily enabled by operating a key switch, inserting an ID card, or entering a password. The visitor enters the room when the outside sensor 12 is temporarily enabled by the resident entry operation after interacting with the resident through the intercom.
