Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention can be easily stored in a Buddhist altar and can increase the opening/closing range of the door body by fixing the horizontal arm for opening and closing the door body to a movable piece. Regarding door opening/closing devices.

[Conventional technology]

It is often difficult to open the outer door of a Buddhist altar in front of which a Buddhist altar is placed, or the door of a zushi inside the altar, especially the door of a large Buddhist altar, by hand. For this reason, Buddhist altars are sold that are equipped with door opening/closing devices that automatically open and close the doors. However, in conventional door opening/closing devices, for example, the door body was attached directly to a nut fitting that was screwed onto a screw shaft that was rotated forward and backward by an electric motor. It tends to occur easily, has poor functionality, and makes the Buddhist altar look bad.

Therefore, one of the present applicants is
According to the publication, a movable piece that moves on a rail arranged parallel to an endless band wrapped by rotating bodies on both sides and a door insertion shaft guided by a guide groove can be rotated by an arm. We proposed a Buddhist altar device with pivot support.

Also used as an opening/closing device for Buddhist altar doors.
The publication also discloses a device in which upper and lower guide grooves are provided for guiding the opening and closing of the door, and the door is opened and closed by an endless belt.

[Problem to be solved by the invention]

However, all of the above-mentioned proposals are based on the assumption that the door is directly guided by a guide groove provided in the ceiling plate or floor plate.

However, such guide grooves are installed in ceiling panels or floor plates, and are generally long, making machining difficult and costly, and the play between them and the guide grooves causes play when opening and closing the door. Cheap.

The present invention is based on the principle that the door is opened and closed by a horizontal arm fixed to a movable piece that slides on a rail, without providing a guide groove to guide the door.
The purpose is to provide a Buddhist altar that has a simplified structure and is easy to manufacture.

[Means to solve the problem]

The present invention provides a pair of doors that can be opened and closed at the front of the box by pivoting an outer door piece to one side edge of the inner door piece so that it can be folded inward, and pivoting the other side edge of the inner door piece to both sides of the front side of the box part. A Buddhist altar having a door body, an endless band having two running band parts that run in opposite directions by being hooked in parallel to rotating bodies arranged near both front ends of the ceiling plate or bottom plate of the box part; A rail arranged parallel to the endless band and having two grooves;
two movable pieces that slide in the two grooves and are attached to one side and the other side of the running band, respectively; one end is pivoted to the outer door piece of each door body in the closed state; This is a door opening/closing device for a Buddhist altar, which comprises horizontal arms each fixed to the movable pieces attached to the running band part, each of which moves toward the door body on which the one end is pivotally supported.

[Effect]

The movable piece slides in the groove of the rail by being attached to the traveling band that runs in opposite directions, and the other end of the horizontal arm, one end of which is pivoted to the outer door piece of the door body, is fixed to the movable piece. are doing. This makes it possible to omit the guide groove that guides the opening and closing of the door, simplifying the structure and eliminating backlash, allowing smooth and stable opening and closing.

In the embodiment, a sprocket 1 is used as a rotating body.
1 and 12, and sprocket 1 as an endless band.
A chain 13 is used which is connected in parallel to 1 and 12. In this specification, "horizontal arm 16,
17'' means an arm that moves horizontally, and does not mean that the arm itself is horizontal.

Referring to FIG. 2, the door opening/closing device 1 is connected to the Buddhist altar 2.
It is installed on the top surface of the ceiling board 4 of the zushi 3 installed inside the room. The Buddhist altar 2 has an upper cover box 30 attached and a lower cover box 31 with appropriate drawers installed below, as well as side plates 34, 34 and a back plate 35 between the upper plate 32 and the lower plate 33. Further, a folding door-shaped door body 5 is pivotally mounted on both front sides of both side plates 34, 34, respectively.

The Zushi 3 shares the back plate 35 within the Buddhist altar 2, and has approximately half the depth and width of the Buddhist altar. Between the ceiling plate 4 and the bottom plate 18 of the zushi 3, there are side plates 36 extending forward from the back plate 35,
36 is erected, and a pair of door bodies 5 are provided on its front edge. The door body 5 is a folding door that pivotally supports an inner door piece 6 and an outer door piece 7 so as to be foldable inward, and the other side edge of each inner door piece 6 is pivotally attached to the front end surface of a side plate 36, respectively. On the other hand, the ceiling plate 4 has a gap between it and the upper plate 32, and the door opening/closing device 1 is housed therein, and the front wall 37 thereof rises and comes into contact with the lower surface of the upper plate 32.

As shown in FIG. 1, the door opening/closing device 1 has a rail 20 arranged parallel to the front wall 37 in front of the ceiling plate 4, and the L-shaped members 40 at the left and right ends of the rail 20 are arranged in parallel with the front wall 37 in front of the ceiling plate 4. 42 to the ceiling plate 4 with screws. The vertical portions 41 of each L-shaped member 40 rotatably support the sprockets 11 and 12, respectively, so that the sprockets 11 and 12 can be disposed near both front ends of the box portion 4, respectively. A chain 13 is stretched between sprockets 11 and 12, and one sprocket 11
The sprocket 11 is driven by the reduction motor 25 by being connected to the rotating shaft of the reduction motor 25 via a known torque limiter 43. Further, even if the electric motor 25 is stopped, the door bodies 5, 5 can be manually pushed open by sliding the torque limiter 43. A movable piece 14 is attached above and a movable piece 15 is attached below to the parallel band part of the chain 13, and as the chain 13 runs, the movable pieces 14, 1
Move 5 in the opposite direction. On the other hand, the rail 20 is
As shown in FIG.
A slide piece 46 made of plastic, for example, is slidably inserted into the holes 4 and 45. The slide piece 46 is connected to the movable pieces 14 and 1 by bolts 47, respectively.
Fixed at 5.

Detectors 49 and 50 (Fig. 1), such as micro switches, are installed horizontally at both left and right ends of the rail 20 via mounting pieces 48, respectively, and leaf springs 51 and 52, which are the actuators of the detectors, are installed on the inside. Keep it directed.

Further, the upper movable piece 14 is formed with an extension portion 53 extending upward, and the extension portion is connected to the detectors 49 and 50.
The electric motor 25 is stopped by contacting the leaf springs 51 and 52 of the electric motor 25. Therefore, the movable piece 14
is the leaf spring 5 of both detectors 49 and 50.
1, 52, and both movable pieces 14,
15 are positioned so that they overlap approximately at the center of the rail 20.

Further, the upper and lower movable pieces 14, 15 have horizontal parts 14a, 15a and hanging parts 14b, 1 which project forward, respectively.
5b, and by making the horizontal portion 14a wider than the horizontal portion 15a, the two can cross each other without colliding.

The horizontal arms 16 and 17 extend below the rail 20 and parallel to the rail 20, and the rear end 5
4 is bent vertically upward and fixed to the movable pieces 14 and 15 by bolts, respectively. Moreover, the horizontal arms 16, 17 can be crossed over each other due to their different installation heights. In order to position both horizontal arms 16 and 17 near the lower surface of the ceiling plate 4, the long groove 19 is formed in the ceiling plate 4. The long groove 19 allows the lower ends of both the movable pieces 14 and 15 to be loosely inserted therein, and in this example, is formed in a linear shape with approximately the same length as the rail 20.
On the other hand, the front ends 55 of both horizontal arms 16, 17 are slightly curved outward. Also, the front end portion 55 has a wood screw shaft 5.
6 or the like to pivotally attach it to the upper end of the outer door piece 7. In addition, when the pivot point is set near the front edge of the outer door piece 7, the amount that the front edge of the outer door piece 7 enters into the inside of the zushi 3 when the door body 5 is opened and closed can be reduced. The lengths of the horizontal arms 16 and 17 are as illustrated in FIG.
It is set to approximately half the width of the zushi 3.

FIG. 3 shows a state in which the horizontal arm 17 is located on the right side in FIG. 1 due to the extension portion 53 of the movable piece 14 coming into contact with the leaf spring 52 of the detector 50 on the left side in FIG. show. At this time, the door bodies 5, 5 are closed. When the reduction motor 25 rotates forward, that is, when the sprocket 11 rotates clockwise in FIG. 1, it travels along the chain 13 and moves the movable piece 14 to the right and the movable piece 15 to the left. Further, the movement is made smooth by the slide piece 46 within the rail 20. Due to this movement, the horizontal arms 16, 17 push the outer door piece 7 outward and open it together with the inner door piece 6. For this, horizontal arm 1
6, 17, one end is rotatably pivoted to the outer door piece 7 of the door body 3 when the door body 3 is in the closed state, and one end of each horizontal arm 16, 17 is pivotally attached to the other end. They are fixed to movable pieces 14 and 15, respectively, which are attached to a running band portion that moves toward the door body 3. In addition, in order to perform this opening smoothly, for example, the inner door piece 6
is set so that the inner door piece 6 is not in a straight line with the outer door piece 7 on the horizontal plane, as shown in FIG.

Note that when the extension part 53 of the movable piece 14 comes into contact with the leaf spring 51 of the detector 49 on the right side of FIG. It is open to the position. Next, when the deceleration motor 25 is rotated in the reverse direction, the movable piece 14 moves to the left and the movable piece 15 moves to the right to close the door bodies 5,5.

FIG. 5 shows a modification of the invention, in which the rail 20
Two I-shaped members 21 and 22 are used instead of the E-shaped members.
Use. The slide pieces 60, 61 are I-shaped members 21,
21 and attached to the chain 63 passing above them with bolts 64. On the other hand, the horizontal arms 65 and 66 have rear end portions 67 bent in an inverted L shape, and horizontal portions 68 are attached to the upper surfaces of the slide pieces 60 and 61 with bolts 64, respectively. The horizontal portion 68 at the rear end of the horizontal arm 65 is longer than that of the horizontal arm 66, and since a suitable spacer 69 is inserted between it and the slide piece 61 and bolted thereto, the installation heights are also different. Therefore the horizontal arm 65,
66 is polymerizable and can run past the other arm in the opposite direction.

〔Effect of the invention〕

Since there are no moving parts with gaps, such as conventional guide grooves that guide the door body, the door body can be opened and closed smoothly without rattling, and there is no need to form guide grooves on the ceiling or floor boards, making installation easier. It is easy to use and its structure is simple.
