Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an openable and closable door for partitioning a space, and more particularly to an openable and closable door which is frequently used by powerless users such as the elderly, the disabled, and small children.

[0002]

2. Description of the Related Art Conventionally, a door that partitions a space is provided with a manual type that opens and closes the door manually and a device that is a driving source for opening and closing the door by a driving method of opening and closing, and the door is opened and closed by starting the driving source. It is roughly divided into automatic doors. The former does not require a drive source for opening and closing, and is generally widely used for home use. On the other hand, the latter is mainly used for facilities, because the structure of the door itself is complicated to install a drive source,
Despite the high frequency of opening and closing of doors of stores, buildings, etc., it is convenient when a spatial partition from the outside world is required for visual shielding and maintenance of cooling and heating temperatures. Some automatic doors are equipped with a sensor that detects the human body near the doorway where the door is installed, and there are those that open or close the door with a push button for opening and closing the door when a person approaches the door. . In addition, it is highly convenient for physically handicapped people, powerless elderly people and small children who have difficulty in manually opening and closing large doors installed in facilities, stores and buildings.

[0003]

In the conventional automatic door, when the door is opened and closed, the door runs on its own, causing a pinch accident or a collision accident. In addition, there are many malfunctions,
Even if a person approaching the door did not intend to open or close the door, he could only open and close the door, or could not open or close due to insufficient sensitivity adjustment of the activation sensor. In the case of opening and closing with a push button, which is often used in toilets for the handicapped, it can be opened and closed by the user of the opening and closing operation. However, since the operation method is not known, a closing accident and a closing accident frequently occur. Further, in the conventional automatic door, when the opening and closing of the automatic door is activated, the open / close state is switched between the full open state and the closed state.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a large-sized door such as a facility, a store or a building with a drive source having a relatively small door opening / closing drive capacity. The door opening and closing force is assisted by the user, and the heavy door can be opened and closed with a light operating force.Since the door opens and closes in the same manner as the conventional manual opening and closing door, there is no worry about erroneous operation, and the usability is significantly improved. Another object of the present invention is to provide a highly safe door that can prevent a collision accident beforehand. Another object of the present invention is to provide a toilet booth with high safety by installing the door as a door of a toilet booth for the physically handicapped, thereby preventing the door from being closed or locked out due to inexperience or incorrect operation.

[0005]

In order to achieve the above object, a door that can be opened and closed, which partitions a space, includes a driving source for thrusting the door in the opening and closing direction, and a door opening and closing operation for the door operator. The door is not movable by providing means for movably controlling the drive source in the direction, but the drive source operates so as to assist the opening and closing force of the door opener, so that the user is insignificant. The door can be opened and closed by force, so that even elderly people and children who are weak can open and close with a light force, and the door needs only an auxiliary working force compared to the drive source of the self-running automatic door,
The driving force can be reduced, and the size and cost can be reduced. In addition, even if there is a drive source, the door does not open and close by itself, so the door does not move unexpectedly against the will of the door opener, preventing accidents and collisions from being pinched and highly safe opening and closing It becomes a door.

A second aspect of the present invention is characterized in that a door opening / closing operation force on a door is detected, a thrust direction of the driving source is determined, and the driving source is activated. Similarly, if the person who opens and closes the door holds the door and the handle provided on the door and thrusts in the opening and closing direction, the drive source will operate. There is no convenience.

According to a third aspect of the present invention, when opening / closing is activated, a thrust for opening / closing acts on the door by the provided driving source, and the mode can be switched to an automatic door mode which can move by itself. The convenience is improved because it can be switched.

According to a fourth aspect of the present invention, the drive source is not operated by the switching means and the door is used as a manual door.

According to a fifth aspect of the present invention, the opening / closing door is installed at an entrance of a toilet booth, so that a closing accident or a closing accident due to inexperience or an erroneous operation can be prevented, and an opening / closing operation method is also manual. The usability is improved because it is exactly the same as the open / close door.

According to a sixth aspect of the present invention, the operation of the door drive source is controlled in accordance with the output of a sensor for detecting the presence of a human body provided in the toilet booth. In the event of anomalies, or occupation of tramps due to closed rooms, problems such as poor security, for example, if the human body detection sensor continues to sense continuously for a preset time or more, the door is opened, and safety is high, A safe toilet booth can be provided.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a control flow chart of the opening and closing door of the present invention. When the door operator with the intention to open and close the door thrusts the door in the opening and closing direction to open and close the door (S11), the direction of the thrust is sensed and the driving source is determined (S12). When activated, it operates to assist the door opening and closing force. (S13) If it is determined that there is no continuous opening / closing action of the door opener, the operation of the drive source is immediately stopped (S14), and the movement of the door is also stopped at the same time. Existence of door opening / closing action by door operator (S1
In the case of 1), it is sensed by a door opening / closing force or a torque, or a judgment is made by a slight displacement of the door. The presence or absence of a continuous opening / closing action of the door opener is detected by detecting a continuous door opening / closing force or torque or by touching a handle installed on the door, and continuously operating the drive source. Regarding the drive source, there is no stipulation such as rotary motor, linear motor, hydraulic / hydraulic drive. According to this method, the opening / closing user moves the door to the required opening / closing stroke, and releases the hand from the door or stops the driving source when the opening / closing thrust stops working (S14), and the door stops at an arbitrary position. . At this time, under the control, the door is in a standby state, and when the door needs to be opened and closed again, if the door is opened and closed again, the drive source operates. According to this method, the person who opens and closes the door always receives the assist force when opening and closing the door, so that the door can be opened and closed with a small force.

FIG. 2 shows a control flow chart when the door of the toilet booth of the present invention is installed. When a toilet booth user enters the room and closes the door (S21), the human body detection sensor detects the user (S22) and a timer is set (S2).
3), counting starts (S24). If the human body is continuously detected for a predetermined time or more, the timer counts up (S25), and the driving source of the door is activated,
Open the door. At this time, since the door runs on its own, the output of the drive source is larger than at the time of assist. According to this control method, problems of occupation of a specific person and security can be avoided beforehand, and it is possible to more quickly cope with an abnormal situation such as a user falling down.

FIG. 3 is a control block diagram of the door according to the present invention. The control unit 1 detects the acting force applied to the door by the door opening / closing force detecting means 3 to open and close the door by the door opening / closing force sensing means 3, and detects the direction of the acting force on the door by the door opening / closing direction detecting means 2 to compare. The comparison processing is performed by means A5. The sensing is performed by detecting torque, minute displacement, and the like. The result of the comparing means A5 is sent to the state judging means 7, the control signal of the door opening / closing driving means 9 to be controlled is judged, and sent to the door opening / closing driving means 4 via the output section 8. Further, even during the operation of the door driving source, the continuous force acting on the door by the door opener is sensed by the door open / closed continuity detecting means 4 and sent to the comparing means B2. The information subjected to the comparison processing in the comparison processing B2 determines the control signal of the door opening / closing drive means 9 to be controlled,
It is sent to the door opening / closing drive means 9 via the output unit 8.
