Claims

[Scope of utility model registration request]

The sand in the hourglass passes through the thin hole from the top container.
When the sand falls into the container below, a container is prepared in the middle of the container to catch the sand, and when the container is filled with sand, the center of gravity shifts upward and the container flips over. Make it so that it performs the action of opening the sand. This is the so-called Shishiodoshi cross structure. An hourglass with a music box whose movement activates the music box switch, causing the music box to start ringing. Furthermore, the conventional shishiodoshi frame structure is for water use, not for sand use. There are two types of shishodoshi crosspieces for sand, one in which the part that contacts the switch is placed in a box so that it cannot be seen due to the rotating action, and a device to adjust the amount of sand that falls. be.
