In this device, a pair of folding door-like door bodies are hinged to the front opening of a zushi in a Buddhist altar, and a drive device for opening and closing the door bodies is connected to a two-shaped rail member having a slide piece and to the slide piece. The door body is composed of an endless chain and a rotary electric motor connected to the endless chain, and the door body is opened and closed by supplying power to the electric motor.

(Problems to be Solved by the Invention) The door-side opening/closing device of the Buddhist altar described above has a large number of components and their connections are complicated, so the entire device becomes large-scale and the manufacturing cost increases. The lateral movement range of the parts that open and close the body is large, so sliding,
Since the guides and the like are extended horizontally, the width of the Buddhist altar on which these devices are installed becomes larger than necessary, making them unsuitable for use in narrow rooms, which limits the places they can be placed.

Because the device is complex, it is easy to break down, and because there are many sliding members, there is a lot of sliding resistance (it is difficult to open and close the door smoothly, and the electric motor is large and the power consumption of the drive device is high. big.

It has the following problems.

The present invention has been made in order to solve the above-mentioned problems, and by providing a link mechanism on the door body attached to the box body of the Buddhist altar, which bends and expands with the rotation of the outer door of the door body, To provide a door-side opening/closing device for a Buddhist altar that can easily and smoothly open and close a door body.

(Means for Solving the Problems) The means of the present invention for achieving the above-mentioned object is as follows: The inner door and the outer door are hinged together so that they can be folded inward, and the outer door is attached to the front side of the box body. A pair of left and right door bodies attached to the opening so that they can be freely opened and closed, a rotary lever provided near the attachment part of the outer door and pivoted to the top plate of the box body, and one end of which is attached to the tip of the rotary lever. an operating rod whose other end is pivotably supported by a sliding guide provided at the upper end of the outer door, and whose other end is inserted into a sliding guide provided at the upper end of the outer door so that it can move forward and backward; and an arm whose one end is connected to the end of the operating rod and which is pivotally connected to the upper end of the inner door. a door-side opening/closing device for a Buddhist altar, which comprises: a drive means linked to a rotating shaft of the outer door; A pair of left and right door bodies are attached to the front opening of the box body so as to be openable and closable, and the door body is provided near the attachment part of the outer door, and is pivoted to the top plate of the box body, with its upper end protruding from the top plate. a rotating lever, an operating rod having one end pivoted on the tip of the rotating lever and the other end inserted into a sliding guide provided at the upper end of the outer door so that it can move forward and backward; The door-side opening/closing device of a Buddhist altar is provided with an arm connected at one end and pivotally connected to the upper end of the inner door, and a drive means linked to the rotation shaft of the rotation lever.

(Function) The device of the present invention configured as described above exhibits the following function.

First, a case will be described in which the driving means is linked to the rotation axis of the door body.

The other end of the rotating lever pivoted on the top plate is connected to the arm pivoted on the inner door by an operating rod inserted into the sliding guide of the outer door, and the driving means is connected to the rotating shaft of the door body. When linked together, a door opening/closing device is constructed.

Therefore, when the drive means is operated to rotate the outer door of the door body about the rotation axis in the closed state of the door body, the outer door is gradually opened outward.

At the same time, the rotating lever also rotates with the operating rod inserted into the sliding guide of the outer door, which prevents it from shifting laterally. Since the axes are different, while moving from the position shown by the solid line in Figure 2 to the position shown by the dashed-dotted line in the same figure, the operating rod slides on the sliding guide and moves the arm connected to its tip toward the inner door side. In order to push the inner door, which was in a perpendicular position to the outer door, the inner door rotates outward about the hinge part and is opened and expanded into a rectangular shape.

Furthermore, when the outer door is rotated by the driving means, the outer door becomes substantially parallel to the box, and the opening of the box becomes fully open.

In addition, when the door body is in the open state, when the drive means is operated to drive the rotation axis of the outer door, the door body rotates inward, and the inner door and the outer door are moved from a gap-shaped state. As the operating rod moves inward, the arm is pulled and rotates the inner door inward around the hinge, so the outer door and inner door are at right angles while moving in the fully closed direction. Close the opening of the box.

Next is the effect when the driving means is linked to the mounting shaft of the rotating lever, but the configuration of the opening/closing device in this case is almost the same as the above case, and in the former case, the rotating shaft of the door body is driven. However, as shown in Figure 4, in this case, the mounting shaft of the rotating lever is driven and the outer door is rotated directly through the operating rod inserted into the sliding guide. It is configured to rotate the door body, and its operation is similar to the former, so detailed explanation will be omitted.

As described above, the door body of the Buddhist altar can be opened and closed easily and smoothly by simply rotating the rotating shaft of the door body or the mounting shaft of the rotating lever in the forward and reverse directions using the driving means.

(Embodiment) Next, an embodiment of the door opening/closing device for a Buddhist altar according to the present invention will be described based on the drawings.

Reference numeral 5 denotes a rotating lever provided near the rotating shaft 4 of the door bodies 2, 2 on the lower side of the top plate a of the box body A of the Buddhist altar 1, and one end of which can be freely rotated to the top plate a by a mounting shaft 6. A shaft 9 is attached to an operating rod 8 whose other end is inserted into a sliding guide 7 provided at the upper end of the outer door 2f.

Reference numeral 10 denotes an arc-shaped arm having a shaft 11 attached to the other end of the operating rod 8. One end is pivotally connected to the upper end of the inner door 2e by the shaft 12, and when the operating rod 8 is pushed and pulled, the inner door 5i2e is attached to the hinge 3. It opens and closes around the center.

13, 13 are driving means for opening and closing the door bodies 2, 2;
In the case shown in Figures 3 to 3, the state is shown in which the door bodies 2, 2 are connected to the rotation shaft 4, and a motor I6 with a reduction mechanism 5 supported by a mounting piece 14 provided on the top plate a is used. The deceleration line 15
A small gear 18 is attached to the output shaft of the motor 16 via a friction joint 17, and the small gear 18 is meshed with the large gear 19 which is pivotally supported on the rotating shaft 4 protruding from the top plate a, thereby further decelerating the motor 16. The forward and reverse rotations are transmitted to the rotation shaft 4, and the door bodies 2, 2 are opened and closed at a predetermined low speed.

Further, as shown in FIG. 4, a case is shown in which the rotating lever 5 is linked to the mounting shaft 6, but since the structure of the driving means 13 is the same, detailed explanation will be omitted.

Although this driving means 13 uses two motors 16,
Although not shown in the drawings, one may be attached to the center of the top plate, and a chain or the like linked to a chain wheel attached to the rotating shaft may be provided on this output shaft to drive the door body 2.2.
