Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a Buddhist altar whose mechanism is extremely simplified by opening and closing the door body of the Buddhist altar using a rotating arm.

Traditionally, Buddhist altars have been known in which the inner door of the altar is opened and closed using an electric motor, but in the conventional one, a guide pin erected at the tip of the door body is connected to a guide groove provided in the ceiling or bottom plate of the altar. The guide pin was inserted into the guide pin and connected to the inward projecting end of the guide pin to open and close the door body by reciprocating the guide pin using a reciprocating means connected to the inward projecting end of the guide pin. When the door is a double door that opens in both directions, the guide groove becomes long, and the ceiling plate or bottom plate extends beyond the main body and protrudes outward, resulting in a lack of balance and the guide groove being visible from above or below. , making the Buddhist altar look bad.
