Description

[Detailed Description of Device] a. Purpose of the Invention (Industrial field of application) The present invention relates to a Buddhist altar that automatically opens and closes the front cover plate of the kitchen of the Buddhist altar.

(Prior Art) The front of a kitchen, which is used to enclose tiles, etc., installed inside a Buddhist altar is usually covered with a door so that it can be opened and closed.

Conventionally, some so-called automatic Buddhist altars that open and close this automatically by a drive mechanism have been considered and are known, and this cover plate is horizontally divided into several pieces and each cover plate piece is arranged in front and back. An automatic Buddhist altar of the tension type is also known, which is opened or closed by hanging up or down by a drive mechanism. (Japanese Patent Laid-Open No. 62-258615) However, in this system, since all of the cover plate pieces are raised or lowered all at once, a large torque is applied to the drive, and therefore, a motor having an ability to cope with this is required. Etc. required a driving source. As a result, there was a problem in space such that a jarring driving sound was generated during the work, the atmosphere of faith was destroyed, and a large motor or the like had to be incorporated in a narrow kitchen. There is also a problem that the life of the motor is shortened because a large torque is applied.

(Problems to be solved by the invention) Therefore, if a Buddhist altar with a cover plate opening / closing mechanism that can handle comparatively small motors does not require much torque, it is possible to reduce the drive noise drastically and save space, such as motors. A Buddhist altar with a long drive life, that is, a long product life can be obtained.

B. Configuration of the Invention (Means for Solving the Problems) In order to solve the above problems, a Buddhist altar according to the present invention has a first cover plate piece and a second cover plate piece in which the front of the kitchen of the Buddhist altar is erected vertically. And a third cover plate piece, and the sum of the weights of the first cover plate piece and the second cover plate piece is set to be substantially the same as the weight of the third cover plate piece, and a drive source is provided in the vicinity of the kitchen. And a rotary shaft operatively connected to the drive source are provided, and a first string hanging the first cover plate piece and a second string hanging the second cover plate piece are in the same direction with respect to the rotary shaft. The third cord, which is wound and the third cover plate piece is hung, is wound in the opposite direction to the first cord and the second cord with respect to the rotation axis.

(Operation) According to the above configuration, the rotation shaft is rotated in the forward or reverse direction by the operation of the drive source, the first cover plate piece and the second cover plate piece are simultaneously raised or lowered, and the third cover plate piece is Move down or up to open and close the front of the kitchen.

Since the sum of the weights of the first cover plate piece and the second cover plate piece is set to be substantially the same as the weight of the third cover plate piece, the forward and reverse load torques applied to the rotating shaft are offset, The load applied to the drive source is almost the same as when the rotating shaft is spinning.

Since the first cord, the second cord, and the third cord are wound around the rotary shaft as they are, the first cord, the second cord, and the third cord can be wound around the rotary shaft without a component for changing the winding and rewinding directions. The front of the kitchen is opened and closed by direct power transmission by forward and reverse rotation.

(Embodiment) An embodiment of the present invention will be described with reference to FIGS.

FIG. 1 shows the inside of the Buddhist altar, and the front surface of the kitchen 1 is covered with first to third cover plate pieces, for example, cover plate pieces a, a ', b. a and a'are raised and opened to be accommodated in the top plate upper chamber 5, and b are lowered and opened to be accommodated in the bottom plate lower chamber 6.

Reference numerals 8 and 8 denote guide rails that penetrate from the top plate upper chamber 5 to the bottom plate lower chamber 6.

2 and 3, when the drive source motor 2 is actuated, the pulleys 3a, 3a ', 3b attached to both ends of the rotary shaft 20 via the speed reducer 4 rotate, and the cover plate piece a, Winding cords 11 attached to both upper sides of a ′ and b
A to string 11C is wound up by the rotors 7 and 7 on the upper side. Since the diameter of the pulley 3a 'is designed to be twice the diameter of the pulleys 3a and 3b, the rotation of the drive source 2 causes the other two pulleys 3a and 3b to rotate.
2 times the length of the string 11A is wound up, and as a result, the cover plate piece a '
Can be accommodated in the upper chamber 5 without being behind the other cover plate pieces a and b.
Further, since the cord 11C attached to the cover plate piece b is wound around the pulley 3b in the opposite direction to the other pulleys 3a and 3a ', the pulleys 3a and 3a' wind the cord and cover plate piece a. , a'to pull up the cord 11A and the cord 11B to lower the cover plate piece b, and conversely, when the pulleys 3a and 3a 'pull out the cord 11A and the cord 11B to lower the cover plate pieces a and a'. And the cover plate piece b is pulled up to operate.

Since the cover plate piece b has a thickness that is about twice the thickness of the cover plate pieces a and a ', its weight is almost the same as the combined weight of the two. At the time of winding up, almost the same torque acts in the opposite direction on the pulleys, so they cancel each other out and wind up with a very small driving force, that is,
The cover plate pieces a and a'b can be opened and closed.

A limit switch (not shown) that operates according to the completion of pulling up the cover plate pieces a and a ′ (completion of opening) and the completion of pulling up the cover plate piece b (completion of closing) is provided, and The rotation direction is switched.

C. Effects of the Invention As described above, the front of the kitchen of the Buddhist altar is covered with the first cover plate piece, the second cover plate piece, and the third cover plate piece that are vertically movable, and the first cover plate piece and the second cover plate piece The sum of the weight of the cover plate piece is set to be substantially the same as the weight of the third cover plate piece, a drive source and a rotary shaft operatively connected to the drive source are provided in the vicinity of the kitchen, and the first cover is provided. A first string hanging a plate piece and a second string hanging a second cover plate piece are wound in the same direction with respect to the rotating shaft, and a third string hanging the third cover plate piece is attached to the rotating shaft. On the other hand, the first and second cords were wound in the opposite direction.

The rotation axis is rotated forward or backward by the operation of the drive source, and the first cover plate piece and the second cover plate piece are simultaneously raised or lowered, and the third cover plate piece is lowered or raised to raise the front face of the kitchen. Open and close.

Since the sum of the weights of the first cover plate piece and the second cover plate piece is set to be substantially the same as the weight of the third cover plate piece, the forward and reverse load torques applied to the rotating shaft are offset, The load applied to the drive source is almost the same as when the rotating shaft is spinning. Therefore,
Space can be saved by reducing the size and weight of the drive source, and drive noise and vibration when opening and closing the front of the kitchen can be reduced.

Since the first cord, the second cord, and the third cord are wound around the rotary shaft as they are, the first cord, the second cord, and the third cord can be wound around the rotary shaft without a component for changing the winding and rewinding directions. The front of the kitchen is opened and closed by direct power transmission by forward and reverse rotation. Therefore, the structure can be further simplified and downsized.
