DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic sliding door device for automatically opening and closing a sliding door provided in a house or the like.

[0002]

2. Description of the Related Art In recent years, various automatic sliding door devices have been provided for automatically opening and closing a sliding door provided in a house or the like. The main starting methods for these automatic sliding door devices are the power assist system and the remote control operation system. In order to respond to a variety of consumer needs, the automatic sliding door automatically opens and closes when a human body is detected. A sliding door equipped with the device is provided.

A conventional sliding door provided with the above automatic sliding door device will be described with reference to an embodiment shown in FIG. FIG. 5 shows a front view of an automatic interior sliding door for a house, in which a sliding door 2 is suspended from a drive motor built-in rail 1 provided above a house opening. A starting sensor 3 is attached to the sliding door 2 and a control device 4
There is built-in. Since the activation sensor 3 and the control device 4 are connected by a dedicated cord provided inside, the activation sensor 3
When a human body is detected in the above, the sliding door 2 is automatically opened and closed by moving the sliding door 2 on the drive motor built-in rail 1. It should be noted that a distance measuring sensor is used as the activation sensor 3, and a response is made by holding a hand or the like over the sensor unit.

[0004]

However, the above-mentioned prior art has some problems. First of all, as an issue at the manufacturing stage, it is necessary to manufacture sliding doors exclusively for automatic sliding doors, so it is necessary to prepare a dedicated assortment of automatic sliding doors in order to respond to user requests. No.
Also in the construction stage, when hanging the sliding door, a special code connecting the start sensor and the control device is inserted into the sliding door,
In addition, there is a point that the work is troublesome because the connection is required. In addition, while the activation sensor installed in the sliding door moves with the opening and closing of the sliding door, the control device is fixed and does not move, so there is a danger that the dedicated cord connecting both will break. There is also. In addition, regarding the detection of the human body, with the conventional activation sensor, the sliding door is activated immediately after the detection of the human body by the sensor, so depending on the layout of the house or the arrangement of the sliding door, a passing person etc. is detected and the sliding door is opened and closed unnecessarily. The point was the challenge.

The present invention has been made in view of the above points, and can be manufactured using a conventional sliding door without installing a dedicated cord and without newly manufacturing a dedicated sliding door. An object is to provide an automatic sliding door device having a function of preventing unnecessary opening and closing.

[0006]

In order to solve the above-mentioned problems, an automatic sliding door according to the present invention is provided with a remote controller for receiving a remote control signal generated by an operation remote controller and outputting a door opening signal to a control unit of the automatic sliding door device. A remote control signal that has a signal receiving unit and a human body detection unit with a distance measurement sensor and a remote control signal transmission unit, and causes the remote control signal transmission unit to output a door open signal from the remote control signal transmission unit to the human body detection by the human body detection unit. And an automatic sliding door device that emits Thus, not only when the operation remote controller is used but also when the human body detection unit detects a human body, a remote control signal for outputting the door open signal to the control unit is transmitted to the remote control reception unit.

Further, when the remote control signal emitted from the remote control signal transmitting unit is infrared, the signal is reflected once on the floor surface and received by the remote control signal receiving unit. It is not necessary that the remote control signal transmitting section and the remote control signal receiving section have a positional relationship in which the remote control signal can be directly received.

[0008] Further, by setting the time point at which the remote control signal is transmitted from the remote control signal transmitting section to the time point at which the human body detection by the human body detection section has been continued for a predetermined standby time or more, the human body detection is performed for a short time. In this case, the remote control signal is not transmitted, so that a malfunction caused by detection of a pedestrian or the like who does not intend to open the sliding door can be prevented.

Also, by making the standby time adjustable,
The user can set the time from detection of the human body to transmission of the remote control signal at his / her convenience.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below based on embodiments shown in the accompanying drawings. FIG. 1 is a schematic view of an automatic sliding door using an automatic sliding door device which is an example of an embodiment of the present invention. A mover 5 made of a permanent magnet is fixed to an upper end of the sliding door 2, and a stator 6 made of an armature coil is fixed inside the upper frame 7 so as to face the mover 5. The stator 6 is connected via a lead wire to a motor control unit 8 also housed in the upper frame 7. The motor control unit 8 is provided with a remote control signal receiving unit 9. When a remote control signal 20 is received from the operation remote control 10, the remote control signal receiving unit 9 outputs a door opening signal to the motor control unit 8. A remote controller signal receiving section 9a is provided on the opposite side of the motor control section 8 with the sliding door 2 interposed therebetween, and the sliding door 2 can be opened and closed using the operation remote controller 10 from the opposite side.
Upon receiving the door opening signal, the motor control unit 8 controls the excitation of the armature coil, and utilizes the attraction and repulsive force generated between the stator 6 and the movable element 5 by the armature coil between the stator 6 and the permanent magnet. Open and close. In this embodiment, the linear motor system using the stator 6 and the movable member 5 is employed as the driving system as described above, but another driving system may be employed. In this embodiment, the remote control system is of the infrared type, but may be of the radio wave type. However, in the case of the radio wave type, it is not necessary to provide the child remote control signal receiving section 9a.

The above configuration is substantially the same as that of the conventional remote-control-operated automatic sliding door device. However, in the present embodiment, the sliding door 2 is further positioned above the upper frame 7. Are provided with a pair of remote controllers 11 with built-in distance measurement sensors. The remote controller 11 with a built-in distance measuring sensor has a human body detecting unit 12 and a remote control signal transmitting unit 13, and the human body detecting unit 12 uses a distance measuring sensor 14 for detecting a human body or the like. Here, the distance measuring sensor 14 is a sensor that detects a human body or the like by the light emitting element 14a and the light receiving unit 14b illustrated in FIG. 4 and measures the distance to the detected object.

As shown in FIG. 2, the remote control 11 with a built-in distance measuring sensor is used after the distance measuring sensor 14 of the human body detecting section 12 detects a detected object within a specified inspection distance, that is, within a distance measuring sensor detection area 14a. The remote control signal transmission unit 13 provided in the driver 16 transmits the remote control signal 20 only when the predetermined standby time has elapsed and the detection is continuing. Further, the remote control 11 with a built-in distance measuring sensor is provided with a remote control signal 20 at a constant remote control transmission period as long as the detected object is detected in the distance measuring sensor detection area 14a.
Is repeated, the malfunction of the sliding door 2 is prevented even in the event of remote control reception loss. Since the above-mentioned inspection distance can be set freely, it is possible to prevent the remote control signal 20 from being transmitted when detecting a pet, an infant on all fours, or the like. The standby time is set by the variable resistor 15 for setting the remote control transmission weight provided in the control circuit 16.

FIG. 3 shows the timing of transmitting the remote control signal 20 more specifically. Distance sensor 1
4 outputs a distance measurement sensor signal by detecting the object to be detected, and transmits the remote control signal 20 by the output.
The remote control signal 20 is not transmitted until the waiting time A of 5 seconds elapses. If the distance measurement sensor signal is continuously output during the standby time A, the remote control signal 20 is transmitted at the end of the standby time A, and the output of the distance measurement sensor signal is output before the standby time A elapses. If it has been completed, the remote control signal 20 is not transmitted. This prevents a malfunction such as opening of the sliding door 2 due to detection of a pedestrian or the like. In addition, in order to prevent the sliding door 2 from malfunctioning due to lack of remote control reception, the above-mentioned transmission is performed twice at a time.

In order to further prevent the sliding door 2 from malfunctioning, the remote control signal 20 is repeatedly transmitted at a remote control transmission cycle B of 0.5 seconds while the distance measurement sensor signal is continuously output. However, regarding the transmission of the remote control signal 20 for the second and subsequent times, even after the transmission of the previous remote control signal 20 has been completed, the transmission of the remote control signal 20 is stopped.
If the distance sensor signal is output continuously for two seconds or more, the remote controller signal 20 is transmitted even if the distance sensor signal has not been output when the remote controller transmission cycle B has elapsed. Conversely, if the output of the distance measurement sensor signal is stopped 0.2 seconds before the end of transmission of the previous remote control signal 20, the remote control signal 20 is not transmitted.

In this embodiment, the standby time is set to 0.5 seconds as described above. However, the user uses a volume (not shown) provided in the apparatus to change the standby time in a range of 0 to 3 seconds in increments of 0.5 second ( That is, 0, 0.5, 1.0, 1.5, 2.0, 2..
The waiting time can be adjusted (to 5.3.0 seconds). Therefore, for example, by setting the standby time to 0 second, the remote control signal 20 can be set to be transmitted when the distance measurement sensor 14 detects the detection target.

A remote control signal 20 transmitted from a remote controller 11 with a built-in distance measuring sensor is received by a remote control signal receiving section 9 provided in the motor control section 8 or a child remote control signal receiving section 9a, and a door opening signal is output. The above procedure is the same procedure as the opening / closing of the sliding door 2 by the operation remote controller 10, and the remote control signal receiving unit 9 and the child remote control signal receiving unit 9a use the operation remote controller 10 and the human body detecting unit 12 respectively. Also used for reception.

However, when an infrared remote controller is used as in this embodiment, the remote controller 1 with a built-in distance measuring sensor is used.
Since it is difficult to transmit the remote control signal 20 directly from 1 to the remote control signal receiving unit 9 and the child remote control signal receiving unit 9a due to the mutual positional relationship, the signal is once reflected on the floor and then received.

[0018]

The following effects can be obtained by the automatic sliding door device of the present invention. First, in the manufacturing stage, the automatic sliding door device of the present invention can be made by simply adding a remote controller with a built-in distance measuring sensor to the automatic sliding door device using the operation remote controller already provided, so that sliding doors of various designs can be used. It is not necessary to manufacture the sensor from a user, and it is possible to easily cope with a plan change such as addition of a sensor function by a user. Also, since the door opening signal by the human body detection is transmitted wirelessly, it is not necessary to provide a special code which has been required in the past, so that the construction work can be simplified. In addition, there is no fear that the dedicated cord is broken by opening and closing the sliding door. For human body detection, use of a distance measurement sensor prevents unnecessary opening and closing of the sliding door due to detection of pets and infants, and by appropriately adjusting the time from detection to motor activation, detection of pedestrians etc. Unnecessary opening and closing of the sliding door can also be prevented. Furthermore, the remote control signal receiving section receives both the remote control signal from the remote control with a built-in distance measuring sensor and the remote control signal from the operation remote control, and may approach and detect itself to open and close the sliding door, The sliding door may be opened and closed using the remote control from a distance. Therefore, the method of opening and closing the sliding door according to circumstances can be selected.

When the infrared remote control system is adopted, the remote control signal transmitting unit and the remote control signal receiving unit are mounted above the sliding door so that both the remote control signal transmitting unit and the remote control signal receiving unit face the floor by using the floor reflection of the remote control signal. Can also be used.
