Description

  The present invention relates to an automatic opening / closing folding door, and particularly to an automatic opening / closing folding door that can be opened and closed by folding the door without providing a motor or a speed reduction mechanism that generates a large torque.

  An automatic door device that opens and closes a door using an electric motor is configured to input a detection signal from a means for detecting an object such as a human body installed at an entrance of the automatic door to a microcomputer to rotate the motor forward and backward. It has a configuration and a structure for controlling opening and closing.

  In general, there are various automatic doors depending on the application, such as an automatic door device that opens and closes two doors and an automatic door device that opens and closes four doors left and right. In the case of four doors, there are a sliding automatic door device that opens and closes by sliding the two doors left and right, and a folding door automatic door device that opens and closes the two doors by folding left and right.

  As a conventional automatic opening / closing mechanism of a folding door, as shown in the plan views of FIGS. 12 (A) and 12 (B) like Patent Document 1, the hinge shaft b of the door a is directly driven, and Patent Document There is known a mechanism that converts a linear motion of a drive strip into a rotational motion by a torque arm such as 2 and can fold a folding door.

No. 4-25190 Japanese Patent Publication No. 1-19031

  However, in the case of the direct drive method disclosed in Patent Document 1, the hinge shaft b is directly rotated by the drive shaft, and thus the structure is simple. However, it is necessary to apply a considerable torque to the hinge shaft b. Not only the machine parts, but also the drive shaft must be designed with consideration of a considerably high safety factor in terms of strength.

  Also, in terms of opening and closing operations, if there is no compression coil spring, there are disadvantages such as problems occurring when changing from fully open to closed operation, and power must be constantly supplied to the motor to compensate for this. Is also pointed out.

  Furthermore, before the fully opened and fully closed state, the switching mechanisms c and d (limit switch, reed switch, etc.) for performing the deceleration operation and the switching mechanisms e and f for performing the stopping operation are driven. If the adjustment is performed on the shaft, it will naturally be subject to some restrictions in terms of the installation space and the shape of the detection switch. Therefore, the adjustment of the set angle θ shown in the figure is also subtle and very difficult. Become. As shown in FIGS. 13A and 13B, the power of the drive shaft k may be transmitted to the reduction gears g and h, and the switching mechanisms c, d, e, and f may be disposed respectively. Further, since the operation cams i and j and a magnet (not shown) are also required, the mechanism becomes complicated.

  Therefore, recently, a means of detecting and controlling the rotation speed and direction of the motor with an encoder or a hall element has been adopted, but the detection device is expensive, the control circuit becomes complicated, and the cost is high. There is a difficulty that becomes.

  Further, in the case of the torque arm type of Patent Document 2, since the opening / closing operation can be easily performed by applying the principle of the automatic opening / closing door in the sliding door, compared with the above-described direct drive method, one of the sliding door parts is used. The sliding door principle can be applied as it is for the closing operation from the open state to the fully closed state.

  For this reason, the switching mechanism can be easily set and adjusted so that the deceleration operation before full opening and full closing can be performed, so that a smooth opening and closing operation can be obtained, but the operation when starting to open from the fully closed state The most important problem of this mechanism is how to switch between them with smooth operation.

  That is, in the case of a manual folding door, since a pulling operation is performed after folding the folding door by pushing a desired position by hand, a series of opening operations can be obtained, but in the case of an automatic folding door, FIG. As shown in A), (B) and (C), since the center position line m of the door hinge L connecting the doors a and a ′ does not exceed the center position line n of the door, the folding operation is not performed. As an initial operation, a mechanism for changing the linear motion of the drive belt (not shown) into a rotational motion is required.

  Various mechanisms have been proposed as means for changing the linear motion into the rotational motion, but all require a large number of arms, links, guide parts, and the like, which complicates the structure.

In addition, this type of automatic folding door is still low in marketability and is used in limited places where the door pocket space cannot be taken if it is a so-called sliding door type such as a hospital passage. Even if it is standardized, it can be produced only with a very small lot, and the offer price is very expensive.
In addition, the control device has a dedicated specification that matches the motor characteristics and reduction ratio, and the speed reduction mechanism, related parts, and control device are dedicated to folding doors and hinged doors. The selling price is also high.
