Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention enhances the solemnity of the Buddhist altar by providing a shoji-like covering board in the zushi of the Buddhist altar and automatically opening and closing the covering board together with the door of the zushi. The present invention also relates to a Buddhist altar that can be easily operated.

[Conventional technology]

Traditionally, Buddhist altars have been proposed in which the background can be changed by raising and lowering the curtain body.
Conventional curtain bodies are formed on the backs of Buddhist statues, etc., and can be rolled up and down, and do not cover the Buddha statues, etc. themselves.

Note that, as shown in Figure 18, Japanese Patent Publication No. 52-20787 discloses a double-walled structure in which the zushi can be opened and closed by a door a, and the morgue b inside the zushi can be opened and closed by an inner door c. I am suggesting something for the door.

[Problem that the invention seeks to solve]

However, in this latter case, the inner door c is a sliding door that moves in an arc surrounding the mortuary table b inside the zushi, and furthermore, the inner door c is a sliding door that moves inside the zushi.
It is designed as a circular arc door with a closing angle of a quarter arc, ie 90°. Therefore, in order to open the morgue b, the door c must move approximately 90 degrees, and therefore the groove guiding the closed door c becomes approximately circular surrounding the morgue b. . As a result, the depth of the zushi becomes large and the plane of the zushi becomes approximately square, and the Buddhist altar that houses such a zushi also becomes deep and large. This means that when the external dimensions are constant, the dimensions of the enshrined stand c, which is opened and closed by the door c that circulates within the zushi, are small, which impairs the balance with the principal image to be enshrined. Furthermore, in the one in Fig. 18, the inner door c
Even when the zushi is closed, the back plate d of the zushi itself can be seen from the outside through the door c and the inner wall of the zushi, and furthermore, the opening of the inner door c is combined with the fact that only the morgue b is opened. Therefore, it is not possible to enhance the solemnity that accompanies the opening and closing of door c.

The present invention makes it possible to open and close a cover plate that can be reciprocated laterally like a shoji in the interior of a zushi by means of reciprocating opening and closing means, and to double open and close the front part of a mandala, a Buddha statue, etc. together with the door body of the zushi. The purpose of the present invention is to provide a Buddhist altar that enhances its appearance and adds to its majesty, and is also easy to handle by being able to open and close automatically.

By standing up, Zushi B is formed. In this example, the pillar plate 35 is provided with a gap 36 for loosely inserting the cover plates 9, 9, which can shield the back plate 7 of the back of the zushi B by abutting the opposing inner edges with each other. Thus, the pillar plate 35 is divided into a front pillar piece 33 and a rear pillar piece 34.

The inner door body 3 is attached to both front side edges of the zushi B, that is, to the front edge of the front pillar piece 33.

The inner door body 3 is in the form of a folding door, which includes an outer door body 5 and an inner door piece 4 that pivots on one side edge of the outer door piece 5 so that the outer door piece 5 can be folded inwards. Attach the edge to the front pillar piece 33
Support point K1 of the insulation part (shown in Figures 9 to 12)
(It is also possible to pivot the ceiling plate 25 and the bottom plate 26 using a support shaft.) Matanai door body 3
can abut against the hanging wall 28 and close the zushi B with a slight bulge forward along the protrusion 27, and the inner door body 3 can be closed in the closed state as shown in FIGS. 9 to 12. It opens and closes between Y1 and an open state Y2 in which the inner door piece 4 is substantially perpendicular to the pillar plate 35 and the outer door piece 5 intersects with the inner door body 4 at an obtuse angle.

In this example, the cover plates 9, 9 are rectangular plates,
At both ends of the mounting bracket 62 attached to the upper edge, as shown in detail in FIG. 4, there is a rising tube 63 provided with a screw hole, which can be screwed into the screw hole, can be fixed with a lockite, and can be guided at the upper end. roller 6
A support 66 is provided which includes a support shaft 65 having a diameter of 4. The support 66 is loosely inserted into a gap 69 that is continuous with the ceiling plate 25 and is provided laterally to the ceiling plate 25, that is, parallel to the back plate and at a distance from the front edge of the ceiling plate 25. . In this example, the cavity 69 has a narrow slit shape through which the support shaft 65 can pass, and is formed over substantially the entire horizontal length of the ceiling plate 25. Further, a guide 70 is provided in the space 31.

The guide 70 is attached to the upper surface of the ceiling plate 25, and as shown in FIGS. 2 and 4-5,
A pair of substantially U-shaped elongated bodies having empty pieces 71, 71 facing each other at the upper end are used, and a guide 70 is used.
In this example, it extends laterally along the cavity 69 and in a substantially straight line at least within the zushi B.

The support tool 66 is constructed by allowing the support shaft 65 to pass through the gap 69 and by loosely fitting the facing hollow pieces 71, 71 into a guide groove 67 provided around the guide roller 64. can reciprocate while being guided by a guide 70 via a support 66 as shown in FIG.

Further, as described above, the cover plates 9, 9 have supporting parts 66, 66 attached to both sides of their upper edges, and the cover plates 9, 9 are supported upwardly by the supports 66 and are carried through the gap. In this example, the upper part is guided through the support 66 as described above. Also, by separating the space 69 from the front edge of the ceiling plate 25, the cover plate 9 hangs down inside the inner door body 3 and inside the zushi B between it and the back plate 7.

Further, in this example, the cover plates 9, 9 are the pillar plates 35, 3.
On the other hand, the pillar plates 35, 35 are separated by about half the length of the distance between the side plates 23, 23. Further, the cover plates 9, 9 are arranged side by side in the lateral direction, are guided by the guide 70, and can reciprocate in the lateral direction on a straight line.
Accordingly, when moving back and forth, the inner edges facing each other come into contact with each other, so that the back plate 7 of the back part of the Zushi B can be shielded. Further, as the inner edge is separated by the backward movement, the outer edge of the cover plate 9, that is, the edge opposite to the inner edge, is separated from the column piece 35.
, and thus laterally beyond the support point K1. When the inner edges are separated, the back plate 7 is opened, and when the inner edges are movable near the pillar pieces 35, as in this embodiment, the back plate 7 is opened substantially completely. Furthermore, cover plate 9
It is also possible to form the back plate 7 so that only a part of it can be opened.

The cover plates 9 are reciprocated by the reciprocating opening/closing means 11 and are moved toward and away from each other. In this example, the reciprocating opening/closing means 11 is a running body 15 made of a string-like body. For example, it consists of chains 91, 92 and a disc body around which the chains 91, 92 are wound, in this example a chain wheel 90, and the chain wheel 90 is driven by an electric motor m. Also, the cover plate 9

The chains 91, 92 are attached using locking rings 74, 75 at the upper ends of the support shafts 73, which are set upright at substantially midway positions in the width direction.
linked to.

The chains 91 and 92 connect the chain wheels 77 and 77 of the support shafts 76 and 76 at both ends of the guide 70 and the guide 2.
The electric motor m is mounted by an L-shaped frame 79 in the middle of 0.
The chain wheels 90 are wound between the output shafts of the chain wheels 90 in two rows, and the chains 9
1,92 goes around. The chains 91 and 92 are wound around two rows of chain wheels 90 so that they rotate in the same direction, while each chain 9
1 and 92, that is, the running line on the door body 3 side, and the running line on the rear side, that is, on the back plate 7 side, can move in opposite directions. Reverse rotation causes them to reciprocate in opposite directions in the lateral direction.

The locking rings 74, 75 are rotatably supported by the support shaft 73, as shown in FIG. It includes a chain wheel-shaped driven body 93 and a rotating body 94 that is fixed to the support shaft 73 and has a circular recess into which the boss of the driven body 93 is inserted. to absorb both. Therefore, a friction clutch S is formed which causes the two to slip due to an overload exceeding the frictional force. Further, the driven body 93 of the locking ring 74 engages with one side of the chain 91, for example, the front running line, and the driven body 93 of the other locking ring 75
3 is a chain 9 running in the opposite direction to the running line;
3, the cover plates 9, 9 can reciprocate in opposite directions, and when an overload is applied, the friction clutch S slips, changing the rotational state of the electric motor m. The cover plate 9 can be stopped as it is, and overheating of the electric motor m can be prevented.

A support piece 14 extending toward the inner door piece 4 is fixed to the upper edge (can also be attached to the lower edge) of the outer door piece 5 of the inner door body 3, and a rotating arm is attached to the pivot point K2 at the tip of the support piece 14. Pivotally connect one end of 6. The rotating arm 6 is provided at its other end with a support shaft 10 that vertically passes through the ceiling plate 25 and horizontally rotates the rotating arm 6 around a rotation point K3 at the center thereof. The pivot point K3 is the pivot point K21 in the door closed state Y1 shown in FIG. 10, and the pivot point K21 in the door open state Y1 shown in FIG.
It is located on the perpendicular bisector X2 of the line segment X1 connecting the pivot point 22 at No. 2. Also, a stationary link LO connecting the support point K1 and the pivot point K3, a first link L1 corresponding to the pivot arm 6 connecting the pivot point K3 and the pivot point K2, a pivot point K2 and the inner door piece 4 , the second link L2 that connects the pivot point K4 of the outer door piece 5 and the third link L3 that connects the pivot point K4 and the support point K1 and corresponds to the inner door piece 4 form a four-bar chain. . Also, by forming the links L0, L1, L2, and L3 to have unequal lengths, the outer door piece 5 on the extension of the second link L2 can be closed together with the inner door piece 4 formed by the third link L3. , the door can be opened and closed between the open states Y1 and Y2 under various opening operations.

For example, as shown in FIGS. 9 and 10, the line segment X1
By locating the rotation point K3 almost in the vicinity, the outer end 5a of the outer door piece 5 can rotate slightly inward from the closed state Y1, and as shown in FIG. , the outer end 5a of the outer door piece 5 is positioned outside the support point K1 beyond the line segment X1.
moves from the closed state Y1 in the lateral direction, that is, along the front surface of the zushi B, and then rapidly opens to the open state Y2. Furthermore, as shown in FIG. 12, the rotation point K3 is
When positioned inward of the support point K1, the outer door piece 5 moves so that its outer end 5a is substantially parallel to the outer door piece 5 in the closed state Y1, and then opens.

The support shaft 10 is as shown in FIG. 2 and FIGS. 7 to 9,
It is connected to the electric motor M by a transmission means 8 housed in the space 31, and a friction clutch C is interposed in the transmission means 8.

The transmission means 8 includes a friction clutch C attached to the output shaft of the electric motor M, two rows of chain wheels 41 formed on the friction clutch C, and chain wheels 42, 43 fixed to the support shafts 10, 10. and chains 44 and 45 wound between the chain wheels 41 and 42 and between the chain wheels 41 and 43. , and the support shaft 10
As shown in FIGS. 7 and 8, the mounting position is fixed so as to be adjustable by a fixing fitting 49 in which elongated holes 50 are arranged side by side.

The friction clutch C, as shown in FIG.

3, and the driven plate 53 is made of a magnetic material that is attracted to, for example, a ring-shaped magnet piece 54 that fits into a circumferential groove provided on the front surface of the rotary plate 52, so that a friction force corresponding to the attraction force is generated. The rotary plate 52 can drive the driven plate 53 within a range of 10 to 15, and when an overload exceeding the frictional force is applied, the friction clutch C can slip and idle. In the figure, reference numeral 55 denotes an idler, which is attached to the fixing metal fitting 49, and after one chain 45 is tensioned and attached due to the lateral movement of the electric motor M, the idler is installed so as to absorb the deflection of the other chain 44. Can move perpendicular to the line. chain 44 to the other chain 45
By giving a 180° twist, chain 4
4 and 45 can rotate the support shafts 10 and 10 in opposite directions, respectively, and can operate the door bodies 3 and 3 simultaneously in the opening direction and the closing direction.

The electric motors M, m are connected to a control device (not shown) including a timer, for example, and are connected to the inner door body 3 and the cover plate 9.
can be automatically opened and closed over time by operating a switch.

[Effect]

By manually opening the outer door body 24 and operating the switch, the control device drives the electric motor M. The electric motor M operates the transmission means 8 as described above, and operates the chain wheel 41, the chains 44, 45, and the chain wheel 4.
The support shafts 10 and 10 are rotated in opposite directions via the support shafts 2 and 43, and the rotation arm 6 at the lower end thereof is rotated.
As illustrated in Fig. 12, the door body 3 is connected to the outer door piece 5.
However, from the closed door state Y1 along the hanging wall 28, the inner door piece 4
The door is rotated until the door is in the open state Y2, in which the door is substantially perpendicular to the pillar piece 35.

Note that the control device drives the electric motor m after a delay of 2 to 10 seconds, preferably about 5 seconds after the door body 3 starts opening. As a result, the chain 9 of the reciprocating opening/closing means 11
a locking ring 74 that engages with 1,92 different travel lines;
Cover plates 9, 9 shielding the back plate 7 by 75
make a return trip. During the return trip, as the inner edge is separated, the outer edge of the cover plate 9 moves to a position beyond the support point K1 in the lateral direction. In addition, since the cover plate 9 moves in a straight line in the horizontal direction, the cover plate 9 is moved along the back plate 7 as shown in FIGS. Decreases the depth between.

In this way, the cover plate 9 opens the back plate 7, and the cover plate 9
A mandala and a Buddha statue that are offered between this and the back plate 7 can be made to appear.

When the door body 3 is opened, the cover plate 9 finishes opening after a delay of 2 to 10 seconds, for example, 5 seconds, and the main timer of the control device starts to open the cover plate 9 from the opening operation time of the inner door body 3 and cover plate 9. Therefore, after the door body 3 and the cover plate 9 stop opening, the friction clutch C of the electric motor M and the friction clutch S of the locking rings 74 and 75 are set to be long.
By slipping until the electric motors M, m stop, burnout of the electric motors M, m can be prevented. In addition, when the switch is closed, the electric motors M and m operate in the opposite manner to the above, move forward and backward through the cover plate 9, and close the back plate 7 at the back of the zushi B by abutting the inner edge. , closes the door body 3. Moreover, the cover plate 9 moves in a straight line and, by abutting its inner edge, completely blocks the back plate 7 of the zushi B, unlike the one shown in FIG.

Furthermore, when opening the inner door body 3 by hand without operating a switch, the rotation of the rotating arm 6 rotates the chain wheel 44 via the chain wheels 42, 43 and chains 44, 45, and the electric motor M. It can be rotated by idling the friction clutch C without causing the friction clutch C to rotate. Furthermore, the cover plate 9 is also damaged by the idle rotation of the friction clutch S of the locking rings 74 and 75, causing the electric motor m and therefore the chain 9 to
1, 92 can be freely opened while stopped. Furthermore, when the switch is operated manually in the open or half-open state, the inner door body 3 and the cover plate are operated in the opening or closing direction selected by the switch as well as the operation of the transmission means 8 and the reciprocating opening/closing means 11. 9
The door opens and closes to the open/close state Y2 or the closed state Y1 and then stops, and the rotation time of the motors M, m of the main timer that remains after the opening/closing can be absorbed by the friction clutches C, S slipping. In the closed and open states, normal opening and closing operations are possible.

Due to the rotation of the pinion 112, the rack member 11
1, the cover plate 9 can be moved back and forth approximately in a straight line,
The inside of Zushi B can be opened and closed.

Further, in this example, the control device includes limit switches LS1A and LS1 that regulate the reciprocating end of the support 66.
B, and limit switches LS2A and LS2B that regulate the reciprocating end of rotation of the support shaft 10. For example, by driving the electric motor m after the limit switch LS2A is activated, the sequential operation of the cover plate 9 and the door body 3 is possible. It is said that

In the Buddhist altar 1 of the present invention, as long as the cover plate 9 can be opened and closed, various configurations can be employed as the reciprocating opening/closing means 11, such as those using ropes, strings, and those that are pushed open with flexible wires. In addition, the cover plate 9 may be formed in the form of an integral rigid plate or a bendable plate-like body, as long as the cover plates are a pair of left and right and are guided by at least the guide 70 and the inner edge can reciprocate. It can be modified in various ways.
