Abstract

PURPOSE: To enable to open/close a door of Buddhist altar in two steps to select one of two door opening conditions, by fixing a rotary shaft rotated by a motor on a side edge part of an inner door body, rotatably attaching one end of an inwardly foldable operating arm rotated by another motor, and pivotally mounting the other end of the operating arm. CONSTITUTION: The rotation axis 8 rotated by the motor 7 is fastened on the edge of the inner part of the door 5 of each foldable door 4. An end of the inwardly-foldable operating arm 13 rotated by another motor 12 is mounted on each rotation axis 8 so that the arm can be freely rotated. Another end of each operating arm 13 is hinged on the outer part of the door 6 in the foldable door 4. When the door is being open, the motor 7 rotates each rotation axis 8 to open the door and the motor 12 rotates each operating arm 13 to open the door. When the door is being closed, the motor 12 rotates each operating arm 12 to close the door and the motor 7 rotates each rotation axis 8 to close the door.

Description

[Detailed Description of the Invention] *Industrial Application Field The present invention relates to an automatic opening/closing door for a zushi in a Buddhist altar.

*Conventional technology The automatic opening/closing door of the Zushi in a Buddhist altar is the Special Publication Act 1986-3.
The one shown in Japanese Patent No. 7972 is known. This automatic opening/closing door connects an inner door body and an outer door body so as to be foldable inward to form a folding door, and the folding door is connected to a door support column at the side edge of the inner door body.
It consists of a rotating arm that is pivotally attached to the outer door body and rotated by a motor, and is connected to the outer door body.

Problems to be Solved by the Invention The above-mentioned conventional automatic opening/closing door is simply a folding door pivoted to a door support column, which is opened and closed by a rotating arm rotated by a motor. Not only is it monotonous and continuous, lacking solemnity, but it also has the disadvantage that the user cannot select the open state.

The present invention has been made in an attempt to solve these problems.

*Means for Solving the Problems In order to solve the above problems, the automatic opening/closing door of the Zushi in a Buddhist altar provided by the present invention performs opening/closing operations in two stages, and moreover, when the user opens the door, the door can be opened in two open states. It is possible to select one of the following.

That is, in the automatic opening/closing door of the Zushi in a Buddhist altar according to the present invention, a folding door is formed by connecting an inner door body and an outer door body so as to be foldable inward, and a motor is attached to a side edge of the inner door body of the folding door. A rotating shaft is fixed, one end of a bendable operating arm rotated by another motor is attached to the rotating shaft so as to be rotatable relative to the rotating shaft, and the other end of the operating arm is rotatably attached to the rotating shaft. It is characterized by being pivotally connected to the outer door body of the folding door.

*Example The present invention will be specifically explained based on illustrated embodiments.

FIG. 4 is a front view of the Buddhist altar 1. Reference numeral 2 indicates an outer door of the Buddhist altar 1, 3 indicates a Zushi placed inside the Buddhist altar 1, and 4 indicates a pair of left and right folding doors of the Zushi 3's automatic opening/closing doors.

Each folding door 4 is formed by connecting an inner door body 5 and an outer door body 6 so as to be foldable inward. A rotating shaft 8 rotated by a motor 7 is fixed to the side edge of the inner door body 5 of each folding door 4.

That is, for example, a chain 11.11 is wound between two chain wheels 9.9 fixed to the output shaft of the motor 7 and a chain wheel 10 fixed to each rotating shaft 8, and the left and right rotations are performed. axis 8
．． 8 rotate in opposite directions.

One end of a bendable operating arm 13 rotated by another motor 12 is rotatably attached to each rotation shaft 8 . That is, as an example, a hollow shaft 14 is rotatably fitted to each rotating shaft 8, and an inner part 13a and an outer part 13b are connected to the hollow shaft 14 so as to be bendable at a center bending point 13'. Inner part 13 in actuating arm 13
Fix the aOH and chain wheel 15, and connect each chain wheel 15 and motor 12.
A chain 17.17 is wound between two chain wheels 16.16 fixed to the output shaft of the left and right operating arms 1.
3.13 rotate in opposite directions. The other end of each operating arm 13 (the end of the outer portion 3b) is pivotally connected to the outer door body 6 of the folding door 4.

Therefore, when the door is opened, the motor 7 that drives each rotating shaft 8 and the motor 12 that drives each operating arm 13 rotate each rotating shaft 8 in the direction of opening the door. The motor 12 rotates each operating arm 13 in the door opening direction, and when the door is closed, the latter motor 12 rotates each operating arm 13 in the door closing direction, and then the former motor 7 rotates each operating arm 13 in the door closing direction.
is adapted to rotate each rotation shaft 8 in the door closing direction.

*Function The closed state of the folding door 4.4 is shown in the solid line in Figure 2 (symbol A
). When the motor 7 is operated from this state, each rotation shaft 8 rotates the inner door body 5 of each folding door 4 outward. At this time, each actuating arm 13 associated with another motor 12 is bent at the center bending point 13- with the inner part 13a stationary, and only the outer part 13b follows the movement of the folding door 4, so that The door body 6 moves approximately parallel to the outer door body 6 in the closed state (see the chain line in FIG. 2). Outer door body 6 by motor 7
The state in which the door is fully rotated outward (hereinafter referred to as the "intermediate open state")
That's what it means. ) is indicated by reference numeral B in FIGS. 2 and 3. The user may complete the door opening operation in this intermediate door opening state B. Furthermore, when the motor 12 is operated in the intermediate door opening state B, each operating arm 13 rotates in the direction of opening the outer door body 6 of the folding door 4, and the folding door 4 is fully opened. That is, at this time, the inner part 13a of the operating arm 13 rotates outward and pushes the outer part 13b outward, so that the outer door body 6 opens fully outward. This fully open state (hereinafter referred to as the "final open state") is shown by reference numeral C in FIG.

When returning the folding door 4 from the final door state to the open state, the motor 12 is rotated in the opposite direction to return the folding door 4 to the -H intermediate open state B, and then the motor 7 is By rotating the folding door 4 in the opposite direction, the folding door 4 is returned to the open state. In this case, the operations of the folding door 4, the operating arm 13, etc. are reversed from the case of opening the door described above.

As described in detail of the present invention, according to the present invention, the opening/closing operation of the folding door is as follows: closed door state→intermediate open state→final open state→final open state→
It is extremely solemn because it is performed in two stages, from the intermediate door open state to the closed door state. Further, the user can also select either the intermediate door opening state or the final opening state as the door opening state when opening the door.
