JPS6013684B2 - Double door opening/closing device - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an opening/closing device for a double door, particularly a front door of a Buddhist altar "Yoriko", each of which is a folding door.

For example, offerings and flowers are placed in front of the zushi.
When opening and closing the door, there is a risk of overturning the door, so it is not only difficult for elderly people to open and close the door, but double doors are generally not locked when closed, or are often left ajar when opened. There are drawbacks. In view of these points, the present invention provides an opening/closing device that opens and closes a door by remote control, reliably maintains its position when opened or closed, does not damage the appearance, and can be easily modified for existing double doors. The present invention will be specifically described below based on embodiments shown in the drawings.

The figure shows an example in which the present invention is applied to Teruko's double doors as an example of a case.
substrates 22, 32 rotatably supported outwardly with hinges 21, 31 on both sides of the closing portion of the substrate; The respective end plates and the base plate are always biased by tension springs 25 and 35 to the inner surfaces of both plates in the supporting direction, and the lower tips of the respective end plates 24 and 34 are located at the lower front of the kitchen knife 1. It is brought into contact with the formed guide step portion 11.

In the illustrated example, the guide stepped portion 11 is circular, but it is not limited to a circular shape and may be linear.
, 32 are simultaneously rotated by a drive device 4 installed below the kitchen knife 1, and the drive device is driven by a drive motor 41.
A worm wheel 44 attached to a horizontally extending drive shaft 43 is engaged with a drive worm 42 rotated by a worm wheel 42, which is connected to both ends of the drive shaft 43 via universal joints 45, 46 and intermediate ratchets 47, 48, respectively. The driven worms 49 and 50 are installed either directly or together via extendable sleeves 51 and 52, and the driven worms are mounted on rotating shafts 55 and 66 vertically attached to support boxes 53 and 54, respectively. Warm wheel 579
58 are placed next to each other. The rotating shafts 55 and 56 are located on the same center as the hinges 23 and 33 that connect the kitchen knife 1 and the base plates 22 and 32, and the support shafts 6 are attached to the base plates 22 and 32.
.
Make it appear to rotate. Switch cams 81 and 91 are attached to the support shafts 6 and 7 in correspondence with the power release switches 8 and 9, respectively.One cam 81 presses the switch 8 when the door is fully opened, and the other cam 81 presses the switch 8 when the door is fully opened. When the cam 9 is in the closed position of the door, the switch 9 is pressed to open the respective passages to the drive motors 41. When opening and closing the door closed by the above-described configuration, the drive motor 41 is rotated in one direction, for example, in the positive direction, thereby rotating the boards 22 and 32 outward via the left and right support shafts 6 and 7. urge

Accordingly, the end plates 24 and 34 are pulled by tension springs 25 and 35, respectively, and are moved so that their lower tips come into contact with the guide step 111 of the kitchen knife 1, as shown in FIG. That is, the left and right doors reach their respective folded open positions, the switch cam 81 presses the switch 8 to open the doorway, and the drive motor 41 stops. Next, when closing the door, a reversal circuit for the drive motor 4 is closed, and by reversing the motor, both boards 22 and 3 are closed.
2 is laid down in the closing direction, and the folded end plates 24 and 34 are pushed out and moved along the guide portion 11 and expanded against the tension springs 25 and 35 to reach the front of Reiko. In the closed position, the switch cam 91 presses the switch 9 to open the electric circuit and the drive motor 41 stops.

According to the present invention, the left and right doors can be folded and opened by remote control, and when the left and right doors are closed, the folded left and right doors can be sequentially opened and closed, so there is no need to directly touch the doors. For example, when this device is applied to the front door of a zushi, there is no risk of the offerings falling over, and the open and closed positions are reliably maintained, eliminating the drawback of a half-open state like that of a cassette, and the structure is simple. It has the advantage that it can be easily attached to a double door.

Claims (1)

[Claims] 1. In a double-hinged door in which one side of each of the left and right doors is hinged to the side of the opening surface of the casing, and each door is foldable, each door has a bullet that is energized to fold it inward at the folding part. The machine is installed, and a guide step is provided at the front of the casing for guiding the doors, and each door has a support shaft protruding downward from the hinged part with the casing, on the same axis as this. A drive device is housed below the door, and the drive device includes a common motor and an intermediate shaft extending in the horizontal direction. A double door opening/closing device characterized in that the front ends of the left and right doors are pressed against a guide step part by movement to open and close the door.
