Description

[Detailed description of the invention] A. Purpose of the invention (industrial field of application) The present invention relates to a Buddhist altar door opening/closing device, which is an electric type for a Buddhist altar having a quarter door with a semi-cylindrical or semi-long cylindrical front surface. Among those related to opening/closing devices, this invention particularly relates to Buddhist altar door opening/closing devices that use links.

(Prior Art) Many applications have been filed regarding electric opening/closing devices for Buddhist altars having quarter doors, and the applicant has continued to file applications for the following ideas. Among them, those particularly related to the present application will be explained.

Utility Application No. 1983-147217 (Refer to Publication No. 59-1575)
This is a device that uses a cycloidal opening/closing device for the semi-elliptical front door of the Buddhist altar, which opens wide into quarters.

Jitsugan No. 57-154795 (Refer to Publication No. 34222 of Sho 60) This is an idea that uses straight grooves in the double-fold opening of the door of a Buddhist altar that has a cylindrical quarter door on the front.

There are many other related applications, but the five mentioned above
This invention is a completely different drive device from the application.

(Problem to be solved) As mentioned above, the conventional electric opening/closing device for a Buddhist altar with a four-part door uses an arcuate, straight, or curved guide groove drilled in the ceiling to penetrate through the guide groove. Previously, this was done by guiding a guide rod installed at the top of the door, but this invention allows the door to be opened and closed electrically without providing a guide groove on the ceiling, and also changes the opening and closing operation of the door. To provide a Buddhist altar opening/closing device which can freely change opening/closing operation only by changing links without moving an electric motor such as a motor or a drive mechanism part.

B. Structure of the invention (Means for solving the problem) In short, the invention consists of rotating both sides of the four-part door of the Buddhist altar at the rear of the altar, and connecting the door with the hinged door. A link is interposed between the two doors, and the relationship between the links is used to open and close the doors by relative movement of both doors.

(Example of the present invention) The present invention will be explained based on embodiments and with reference to the drawings.

Fig. 2 is a skeleton representation of a Buddhist altar 1 having a quarter door with a semi-elliptical front surface, which was used in an embodiment of the present invention. 5 is provided, the other end of each engages with doors 3 and 4 via hinges 9 and 9, respectively, and when the door is opened wide, it opens like doors 2' and 3'. be.

FIG. 1 is a perspective view of the main parts of the embodiment. A drive device 8 installed on the ceiling (not shown) rotates the door 2 in the forward and reverse directions via a drive shaft 7 that passes through the ceiling.

A bearing piece 10 is provided in front of the upper end of the door 3, which is rotatably engaged with the other end of the door 2 by a hinge 9, and protrudes to the outside of the door 3, and a link 11 is provided at the protruding end of the bearing piece 10. One end is pivoted 12 and the link 11
The other end is pivoted 13 at one end of a fixed plate 6 fixed to the ceiling.

(Operation of the present invention) First, FIG. 3 shows the operation of the present invention. In the figure, 7 indicates the center of the drive shaft 7 of the embodiment, 9 indicates the center of the hinge 9 of the embodiment, 12 indicates the center of the pivot 12 of the bearing piece 10, and 13 indicates the fixed plate 6 and the link 1.
1 indicates the center of the 13 pivot points, 3 indicates the center line of the door 3, and 2 indicates the center of the door 2.

First, it goes without saying that when the door is closed, it is in the position of door 2 and door 3. Then, when the door 2 is moved to 2a by the rotational force of the drive shaft 7, the link 1
Due to the relationship 1, the door 3 is in the state 3a, and the hinge 9
moves to 9a.

In this way, when the door 2 passes through 2a, 2b, 2c and reaches 2', the door 3 also passes through 3a, 3b, 3b,
After passing through 3c, it becomes 3'.

However, once the hinge 9 passes through 9a, 9b, and 9c and reaches 9', it cannot proceed any further. In other words, in FIG. 3, the length of the link 11, that is, the distance between the pivots 12 and 13, has been adjusted so that the door 3 opens 90 degrees to become the door 3'. If the door is to be opened wide, this can be achieved by adjusting the length of the link 11.

Next, FIG. 4 will be explained. Using the same reference numerals as in FIG. 3, door 3 passes through 3a, 3b, and 3c to become door 3', and door 2 passes through 2a, 2b, and 2c to become door 2'. When the pivot point 13 between the link 11 and the fixed plate 6 as shown in the figure is used, the doors 2 and 3 move in a double-opening motion.

The process from the door closed state to the door open state in FIGS. 3 and 4 is as explained above, but when the door 2' is moved to the position 2c by reversing the drive device 8, the above-mentioned link Depending on the relationship, the pivot 1
2' moves to 12c, and therefore door 3' moves to 3c, and the door 2 and door 3 move in a completely opposite movement to the door opening movement.
This is the closed state and the door 2 can no longer be rotated. This is similar to the door opening movement described above, and can be set by the design of the link.

This is a problem that can be proven in terms of link theory.
In Figures 3 and 4, the center of the drive shaft 7 and the hinge 9
When the distance between the pivots 12 and 13 of the link 11 is x, and the distance between the pivots 12 and 13 of the link 11 is y, if x > y, the opening is wide, and if x < y, the opening is double-sided, and the degree of opening is is determined by the relative positions of the center of the hinge 9, the center of the drive shaft 7, and the pivots 12 and 13 on both sides of the link 11.

C. Effects of the present invention According to the present invention, the four-part door of the Buddhist altar can be electrically opened wide or double-opened without drilling a guide groove in the ceiling of the Buddhist altar, and it can meet the requirements for the width of the ceiling of the Buddhist altar. Since the size is reduced, it is easier to adjust the outer shape of the Buddhist altar.
It can be applied to existing Buddhist altars, and when changing the opening/closing operation of the door, you can freely change the opening/closing operation by simply changing the link without moving the motor or drive mechanism. It has great effects, such as being able to do the same thing and being extremely inexpensive.
