Description

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

  An automatic door apparatus that opens and closes a door using an electric motor receives a detection signal from a means for detecting an object such as a human body installed at an entrance of the automatic door and causes the microcomputer to input a detection signal from the means to It is configured and structured to control opening and closing.

  Generally, there are various types of automatic doors, such as an automatic door device for opening and closing two doors and an automatic door device for opening and closing four doors two by two, depending on the application. In the case of a four-sheet door, there are a slide-type automatic door device that slides two doors laterally to open and close, and a fold-door-type automatic door device that folds two doors horizontally to open and close.

  As a conventional automatic door opening / closing mechanism for a folding door, as shown in the plan views of FIGS. 12 (A) and 12 (B) as in Patent Document 1, the hinge shaft b of the door a is directly driven. A mechanism is known in which the linear movement of the drive bar is converted into a rotational movement by means of a torque arm such as 2, and the folding door can be folded.

Japanese Utility Model No. 4-25190 Japanese Examined Patent Publication 1-19031

  However, in the case of the direct drive system of Patent Document 1, since the hinge shaft b is directly rotated by the drive shaft, the structure is simple, but 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 a fairly high safety factor in view of strength.

  Moreover, in terms of the opening and closing operation, without the compression coil spring, a defect occurs when changing from the fully open state to the closing operation, or the electric power must be constantly supplied to the motor to compensate for this. Is also pointed out.

  Furthermore, before fully open and fully closed, drive switching mechanisms c and d (limit switches and reed switches, etc.) for performing the decelerating operation and switching mechanisms e and f for performing the stop operation. If it is provided in the shaft part and adjusted, it will be naturally restricted to a certain extent in terms of the mounting space and the shape and dimensions of the detection switch, and the adjustment of the setting angle θ shown in the figure will be subtle, Become. As shown in FIGS. 13A and 13B, it is conceivable to transmit the power of the drive shaft k to the reduction gears g and h, and to arrange the switching mechanisms c, d, e and f respectively. Since the operation cams i and j and magnets not shown are also required, the mechanism becomes complicated.

  Therefore, recently, means of detecting and controlling the rotational speed and direction of the motor by an encoder or a Hall element has been adopted, but the detection device is expensive, the control circuit becomes complicated, and the cost increases. There is a drawback that it becomes.

  Moreover, in the case of the torque arm type of Patent Document 2, the principle of the automatic opening and closing door in the sliding door can be applied and the opening and closing operation can be easily performed. Therefore, compared with the direct drive system described above, The mechanism of the sliding door can be applied as it is for the closing operation from the open state to the full closing.

  For this reason, a smooth opening / closing operation can be obtained because the setting and adjustment of the switching mechanism can be simplified by performing the deceleration operation before the full opening and the full closing, but the operation when the opening starts from the fully closed state How to make it possible to switch with smooth operation is the biggest problem of this mechanism.

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

  Various mechanisms have been proposed as means for converting linear motion into rotational motion, but many mechanisms, such as arms, links, and guide parts are required, and the structure becomes complicated.

In addition, this type of automatic folding door is still low in marketability, and when it is a so-called sliding door type such as a hospital aisle, it is adopted to a limited place where the door pocket space can not be taken. Even if standardized, they can only be produced in very small lots, and the offered price is now very expensive.
Furthermore, the control device also has a dedicated specification according to the motor characteristics and reduction ratio, and the reduction gear mechanism and related parts and control device are dedicated to the folding door and the opening door, resulting in a large development cost and inventory despite the small demand. There is a problem that the selling price is also high.

  The present invention has been made in view of the above-described circumstances, and an automatic opening and closing door that can be folded and opened smoothly without providing a motor or a reduction mechanism that generates a large torque dedicated to rotating the door. The purpose is to provide.
