Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a Buddhist altar that can enhance the solemnity of the Buddhist altar and simplify its operation by providing a shoji-like covering on the Buddhist altar and automatically opening and closing the covering together with the outer door of the Buddhist altar. .

Traditionally, Buddhist altars have a double-opening inner door at the rear of the front door of the Buddhist altar, and worship objects such as Buddhist statues and memorial tablets are enshrined inside this altar, and the door is automatically opened and closed by electric power when necessary. (see Publication No. 20787),
As a means for automatically opening and closing a door, an automatic door opening/closing device using a rack driven by a pinion of a reversible motor (see Japanese Patent Publication No. 45-12628) is known.

However, in the former Buddhist altar described above, a pair of double doors provided inside the Buddhist altar are opened and closed in an arc shape, so if these pair of doors are arranged side by side in the Buddhist altar, the doors will be formed in a substantially circular shape. As the interior depth increases, the Buddhist altar becomes larger, making its installation inconvenient.

Furthermore, since the opening and closing of the door moves along an arcuate track, the movement gives a modern impression to the practitioners, so the solemnity of Buddhist altars from ancient times in Japan is lost, and it is difficult to harmonize with the exterior of the Buddhist altar. It causes a feeling of discomfort.

In addition, in the latter device, since the racks are mounted above and below with pinions in between, the ceiling of the Buddhist altar must be made higher by the movement stroke of the racks, which has the disadvantage that the Buddhist altar becomes larger. It was hot.

The present invention enables a cover plate that can be reciprocated laterally in a shoji-like manner to be opened and closed by a reciprocating opening and closing means,
A Buddhist altar that enhances the appearance and adds to the majesty of the Buddhist altar by opening and closing the front part of a mandala, a Buddhist statue, etc. in two layers together with the door body, and also makes it easy to handle by being able to open and close automatically. The purpose is to provide

An embodiment of the present invention will be described below based on the drawings.

In the figure, the Buddhist altar 1 has a double door body 3 on the front,
3 is installed, and a pair of left and right covers 9, 9 are installed, the leading edge of which is guided by a guide 70 and can reciprocate in the lateral direction, shielding objects of worship (not shown) on the back as it moves back and forth. On the other hand, the covering bodies 9, 9,
A pinion 112 rotated by an electric motor m and a rack member 11 that meshes with both sides of this pinion 112.
1,111, and is connected to a reciprocating opening/closing means 11 having 1,111.

The Buddhist altar 1 has protrusions 27 and 2 having arcuate ends on both sides.
A slightly narrow back plate 7 and pillar plates 35 extending forward from both side edges of the back plate 7 are provided between a ceiling plate 25 provided with 7 and a bottom plate 26, forming a box shape with an open front. Further, a circular upper plate 2 is provided above and below each of the ceiling plate 25 and the bottom plate 26.
1. A lower plate 22 is arranged, and a lower wall 29 is provided between the bottom plate 26 and the lower plate 22. Also ceiling board 25
By attaching the upper wall 30 between the upper wall 30 and the upper plate 21, a space 31 surrounded by the upper wall 30, the upper plate 21, and the ceiling plate 25 is formed above the ceiling plate 25. A hanging wall 28, which the upper edge of the rear surface of the door body 3 abuts upon closing, is suspended from the lower surface of the ceiling plate 25 along its front edge and at a position away from the front edge. 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 part by abutting the inner edges of the pillar plate 35 with each other. A distinction is made between a pillar piece 33 and a rear pillar piece 34.

The door body 3 is attached to the open portion of the Buddhist altar 1, in this embodiment, both front side edges, that is, the front edge of the front pillar piece 33.

The door body 3 includes an outer door body 5 and an inner door piece 4 that pivotally supports the outer door piece 5 at one side edge so that the outer door piece 5 can be folded inward.
The other side edge is connected to the support point K1 of the front edge of the front pillar piece 33.
(shown in FIGS. 9 to 12). (The ceiling plate 25 and the bottom plate 26 can also be pivotally attached using a support shaft.) Further, the door body 3 is in contact with the hanging wall 28,
The door body 3 can be closed with a slight bulge toward the front along the protrusion 27, and the door body 3 can be closed as shown in FIGS. 9 to 12.
In the closed door state Y1, the inner door piece 4 is almost perpendicular to the pillar plate 35, and the outer door piece 5 is in the inner door body 4.
The door opens and closes between the open door state Y2 and the open door state Y2, which intersects at a pure angle.

In this example, the flat covers 9, 9 are rectangular plates, and as shown in FIG. A support 66 having a support shaft 65 is provided. In addition, a guide 70 arranged along a gap 69 provided in the ceiling plate 25 pivots on both sides of rollers 64, 64 that roll a guide 70 disposed along a gap 69 provided in the ceiling plate 25 via a joint pipe 65b attached to the lower end of the head 65a of the support shaft 65. A tool 72 is provided, and the vertical height of the cover plate 9 can be adjusted by rotating the head 65a. In this way, the covers 9, 9 are traversed while being guided by the guide 70 using the support 66.

The gap 69 through which the support 66 passes is continuous with the ceiling plate 25 and transversely to the ceiling plate 25.
That is, it is provided parallel to the back plate and at a distance from the front edge of the ceiling plate 25. Note that in this example, the cavity 6
Reference numeral 9 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 . The guide 70 is made of a pair of angle members attached to the upper surface of the ceiling plate 25, and one piece thereof forms a projecting piece that guides each outer surface of the guide rollers 64, 64.
In this example, extends in a substantially straight line in the lateral direction along the gap 69.

In the support tool 66, the support shaft 65 passes through the gap 69, and the guide roller 64 passes through the guide 7.
By moving along 0, the covers 9, 9 can reciprocate while being guided by the guide 70 via the support 66.

In addition, the flat plates 9, 9 have supports 66, 66 attached to both sides of their upper edges as described above.
9 passes through the cavity 69 and hangs down into the box part 2 by this support 66. Also, since the gap 69 separates the front edge of the ceiling plate 25, the cover plate 9 hangs inward of the door body 3 and between it and the back plate 7.

Further, in this example, the covering plates 9, 9 are the pillar plates 35,
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 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. The back plate 7 is opened as the inner edges are separated, and when the inner edges are movable near the pillar pieces 35, as in this embodiment, the back plate 7 is opened almost completely. Note that the cover plate 9 can be formed so that only a part of the back plate 7 is opened.

The cover plates 9 are reciprocated by the reciprocating opening/closing means 11 and moved toward and away from each other. One end of the reciprocating opening/closing means 11 is fixed to a mounting piece 110 provided on a support 66 attached to opposite sides of each cover plate 9. Rack member 1
11, and a pinion 112 that meshes with the rack member 111 and is fixed to the electric motor m. Presser rollers 113, 113 for pinching the rack member 111 are suspended from the pinion 112. By engaging the rack members 111, 111 attached to the cover plates 9, 9 on both sides of the pinion 112, the rack members 111, 111 can traverse and reciprocate in opposite directions as the pinion 112 rotates. Further, the pinion 112 is located approximately in the middle of the guide 70 in the length direction, and the electric motor m is fixed downward by the U-shaped frame 109.

The rack member 111 is a long molded product 1 in which rack member teeth are molded using rubber, synthetic resin, etc. on one surface of a substrate 114 having excellent elasticity such as a synthetic resin plate.
16 is attached, and the reciprocating opening/closing means 11 can reciprocate the cover plate 9 in a substantially straight line through the pinion 112 and the rack member 111 by the rotation of the electric motor m, making it possible to open and close the inside of the Buddhist altar 1. .

A support piece 1 extending toward the inner door piece 4 is attached to the upper edge of the outer door piece 5 of the door body 3 (it can also be attached to the lower edge).
4 is fixed, and one end of a rotary arm 6 is pivotally connected to a pivot point K2 at the tip thereof. At the other end of the rotating arm 6,
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.
Equipped with. The rotation point K3 is located on the perpendicular bisector X2 of the line segment X1 connecting the pivot point K21 in the door closed state Y1 and the pivot point K22 in the door open state Y2 shown in FIG. . 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 connecting the pivot point K4 of the outer door piece 5 and the pivot point K
4 and the support point K1, the third link L3 corresponding to the inner door piece 4 forms 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 connected to an electric motor M by a transmission means 8 housed in the space 31, as shown in FIGS. 2 and 7 to 9, 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 metal fitting 49 having elongated holes 50 arranged in parallel.

The friction clutch C, as shown in FIG.
A rotating plate 52 fixed to the output shaft of the electric motor M, and a driven plate 5 having a recess into which the outer periphery of the rotating plate 52 is fitted.
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 the door body 3 and cover plate 9 can be automatically opened and closed over time by operating a switch.

The control device drives the electric motor M by operating the switch. The electric motor M operates the transmission means 8 as described above, and connects the chain wheel 41 and the chain 4.
4, 45, support shafts 10, 10 via chain wheels 42, 43
are rotated in opposite directions, and the rotating arm 6 at the lower end is rotated in opposite directions.
9 to 12, the door body 3 is moved to a closed state Y1 in which the outer door piece 5 is along the hanging wall 28.
The inner door piece 4 is rotated between the opening state Y2 and the opening state Y2 in which the inner door piece 4 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 pinion 11 of the reciprocating opening/closing means 11
2 rotates, and the rack member 11 engages on both sides.
1 and 111 are run in directions away from each other. As a result, the covering plates 9, 9 that shield the back plate 7 are moved back, the back plate 7 is opened, and the manchara and Buddha statue that is offered between the cover plate 9 and the back plate 7 are removed. It 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 the opening of the door body 3 and cover plate 9.
Therefore, after the door body 3 and cover plate 9 stop opening, the friction clutch C of the electric motor M slips until the electric motors M and m stop. Burnout of electric motors M and m can be prevented. In closing, when the switch is closed, the electric motors M and m are operated in the opposite manner to the above, and the cover plate 9 is moved in advance, and the back plate 7 at the back is closed by the abutment of the leading edge. After that, the door body 3 is closed.

13-14 show another embodiment of the invention.

In this embodiment, the door body 3 is provided with a guide roller 106 at the rear end of the support piece 104 provided on the outer door piece 5, and the guide roller 106 is guided by a guide groove 107 provided on the lower surface of the ceiling plate 25, so that the door body 3 has a support shaft. 1
With the rotation of 0, the door body 3 can be opened and closed as shown in FIG.

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 9 and the door body 3 is possible. It is said that

In addition, in the Buddhist altar 1 of the present invention, the covering plate 9 may be formed in the form of an integral rigid plate or as a bendable plate-like body as shown in FIG. As long as the inner edge can reciprocate while being guided, it can be deformed in various ways. In addition to the opening in front of the Buddhist altar, the opening may be an opening in the vicinity of the Buddhist altar.

As mentioned above, the Buddhist altar of the present invention has the following effects.

The covering plate that shields worship objects is formed into a flat plate shape, and is opened and closed linearly by a horizontal guide installed parallel to the open part of the Buddhist altar, so its operation is reminiscent of traditional Japanese temples from ancient times. It makes a strong impression, enhances the majesty of the Buddhist altar, harmonizes with the exterior of the Buddhist altar, and further improves the product value, and since the space required to open and close the cover plate is small within the altar, the altar becomes more compact. It can be manufactured and placed even in a small room.

Since the cover plate opens and closes linearly, there is little failure even after long-term use, and there is very little movement resistance when opening and closing, so it can be operated with low driving force, making it economical as it can use a small electric motor with low power consumption. .

Since the racks are arranged one behind the other on the upper edge of a pair of flat covered plates with pinions in between, there is ample space above and below the top of the Buddhist altar, and there is no need to make the ceiling higher than necessary. , Buddhist altars can be made smaller, leading to cost reductions.
