Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic opening / closing door which can be opened / closed by a remote controller in a house where a physically handicapped person lives, and a device therefor.

[0002]

[Prior Art] Public facilities such as hospitals and government offices, department stores, etc.
The building where an unspecified number of people enter and leave is provided with an automatic opening and closing door using infrared rays, so that people can enter and exit freely just by placing a person near the door. However, since the automatic opening and closing doors provided in buildings as described above are intended for an unspecified number of people, they are automatically opened and closed when people approach, making them unsuitable for private residences from the viewpoint of privacy. It is. In addition, in the case of a house where people with physical disabilities live, not only the door of the entrance, but also the sliding door that separates the room from the corridor or the next room, etc. For those who use crutches, opening and closing are difficult and painful. However, even if the automatic opening and closing door is provided for an unspecified number of people as described above, it may be opened and closed irrespective of the intention of the individual, which may infringe on privacy, etc. If the door has to be opened and closed when there is no supply of
Some actuators and doors need to be opened, which is unsuitable for personal homes where people with disabilities live. Therefore, there is a demand for an automatic opening / closing device that can be retrofitted to an existing house door with a simple structure and that can be provided relatively inexpensively.

[0003]

An object of the present invention is to provide an automatic opening / closing door which can be automatically or manually opened / closed based on the intention of the person.

[0004]

According to the present invention, there is provided a drive shaft having a rotation axis on the same axis as a rotation axis of a door hinge for supporting a door, and the rotational force of the drive shaft is controlled by the door. The door is opened and closed by transmitting it to the hinge. The drive shaft uses the output shaft of the motor or another shaft connected to the output shaft. or,
A pulley may be provided on the drive shaft and the output shaft of the motor, and the torque may be transmitted by a belt.

Further, the configuration comprises a remote controller for instructing the opening and closing of the door by radio or wire, a polarity switching means for supplying power to a motor for applying a door opening / closing force based on a signal of the remote controller, and a motor operation. A controller having a timer function for setting time, a drive hinge having a mechanism for rotating or idling by friction by holding the output shaft of the motor or a drive shaft connected to the output shaft, and connecting to the drive hinge It comprises a clamp for transmitting a rotational force to the door hinge, and a guide for aligning the rotation axes of the door hinge and the drive hinge. Since a drive mechanism that sandwiches the drive shaft and rotates or idles by friction is adopted, it can be manually opened and closed at any time. Radio waves used for transmitting signals with the remote controller can be sound waves, light, radio waves, or the like.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS When "open" or "close" is instructed by a remote controller, the polarity of a DC power supply supplied from a controller is automatically switched and applied to a motor with a reduction gear to operate the motor. A drive hinge connected to the output shaft of the motor or a drive shaft connected to the output shaft via a joint or the like, and having a mechanism that rotates or idles by friction; and a hinge connected to the door hinge by a clamp connected to the drive hinge. Transmits force to open and close the door. Further, the motor operation is stopped at a preset time by a fixed or variable timer provided in the controller unit. The revolving door to which the present invention is applied is not set to automatically release the lock when the door is opened and closed.
It is assumed that the door is unlocked by, for example, closing the latch hole.

[0007]

Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing the whole of the present invention. FIG. 2 is a perspective view showing the inside of the control unit main body and the driving mechanism. In FIG. 1, reference numeral 1 denotes a remote controller having a function of transmitting a signal to open or close a door, 2 denotes a door, 3 denotes a control unit main body, 4 denotes a door hinge supporting the door, 5 denotes a handle, and 6 denotes a handle. Is a latch, 7 is a latch hole,
Reference numeral 8 denotes a receiving unit, and 9 denotes a DC power supply. By operating the remote control 1, a signal of “open” or “close” is transmitted, and the signal is transmitted to the receiving unit 8.
2, a signal is transmitted to a controller 10 provided inside the control unit main body 3 shown in FIG. 2, the polarity of the current supplied from the DC power supply 9 is selected, and the current is supplied to the motor 11 through the conducting wire 12. Then, the door is rotated in the opening or closing direction. As the motor 11, a motor with a reduction gear is suitably used. The drive shaft 14 connected to the output shaft of the motor via the joint 13 starts rotating. The drive shaft 14 is provided with a drive hinge 15 for holding the shaft, and has a clutch function of sliding when the rotation or load increases due to friction. The driving hinge 15 is a cylindrical guide 1.
6 is provided integrally so that it can be easily fitted to the upper end of the rotation shaft of the existing door hinge 4 so that the drive shaft and the rotation axis of the door hinge coincide with each other. Further, a clamp 17 is fixed to the driving hinge 15 by a screw 18 and grips a part of the existing door hinge 4 on the side fixed to the door frame 20. Controller 10 and motor 11
Is fixed inside the case 19, and the case
Fixed to With this configuration, when the drive shaft 14 rotates, the door 2 is rotated to open and close the door with the fixed side of the door hinge 4 screwed to the door frame 20 fixed to the wall as a base point. Even if the drive shaft 14 rotates, the drive hinge 15 rotates in synchronization with the door 2, so that at first, due to inertia due to the weight of the door, for example, the vehicle is in a half-clutch state when the automobile starts. Then, the rotational force is transmitted to the door 2 while sliding in the rotational direction. Eventually, the door 2 is rotated stably in synchronization with the drive shaft 14. When the door is fully opened or fully closed, the rotation is forcibly stopped by a door stopper (not shown) or a door frame 20 or the like. At this point, the state changes from synchronous to sliding, and even if the motor is operating, the door 2 is still operated. It will be stopped. The same applies to a case where there is an obstacle in the rotation range of the door and the rotation of the door is stopped halfway. After that, the operation of the motor is stopped by the timer function built in the controller 10. The signal transmitted from the remote controller is not particularly limited as it uses not only an ultrasonic wave and a light beam but also a sound, and the installation position of the receiving unit 8 may be a door and a wall surface around the door in addition to the control unit main body. In this example, the control unit main body 3 is attached to the door, but it can be operated in the same manner when attached to the wall side. In this case, clamp 1
7 is attached to the side of the door hinge to which the door 2 is fixed.

Further, at the end of the opening or closing operation of the door, when the door hits the door stopper or the door frame, the door rebounds and the door may return, causing a slight gap. By doing so, the previous operation is continued, and the second time, while the speed does not rise sufficiently, the stopper hits the stopper, so that there is little rebound and the convergence gradually. Therefore, an element that increases the cost, such as putting the damper before hitting the stopper or decelerating in advance, is not necessarily required.

The same applies when the door 2 is located in the middle of the rotation range before operating the remote controller 1 to "open" or "close".
However, in this case, since the door 2 is fully opened or fully closed early, the sliding time between the drive shaft 14 and the drive hinge 15 becomes longer.

When the door 2 is further opened from the opened state or further closed from the closed state, the sliding state is maintained as described above until the door 2 is stopped by the timer function. Starts and stops.

When the door 2 is manually operated to rotate the door in the same or opposite direction as the rotation direction of the drive hinge, the drive shaft 14 and the drive hinge 15 are in a sliding state, and the door can be freely opened and closed. . However, if the rotation of the door 2 is stopped manually before the driving hinge is stopped by the timer function, the automatic door 2 is rotated again until the driving hinge is stopped by the timer function.

When the door that automatically opens and closes according to the present invention is opened and closed by a person or the like as usual without relying on a motor drive, the door can be operated in the same manner as a normal residential door. At this time, the vehicle is all slipped.

[0013] Since "stop" can be instructed by the remote controller 1, the operation by the motor drive can be stopped freely.

[0014]

As described above, the door that automatically opens and closes according to the present invention can be easily opened and closed only by a simple remote control at hand even for a person with a physical disability. Because it can be opened and closed only, it has a great effect on privacy protection.

The present invention can be basically handled in the same manner as a conventional door, so that a healthy person does not feel uncomfortable, and at least a normal state can be secured even in the event of an abnormality such as a power failure. Without.

The device of the present invention is easy to install, does not require any special request from a vendor, and does not allow anyone to enter a room or space where privacy is desired. Further, since the device configuration is simple and can be provided at low cost, it is suitable for everyone.
