  • the sandglass stops and remains stopped due to the engagement between the rugged part 216 of the coupling part 212 and the rugged part 216 of the coupling groove 214. Accordingly, the user can adjust the sandglass to a position so that the sandglass is convenient to view or operate.
  • the switch installed at the predetermined position in the upper case 208 is turned ON/OFF, time and date data calculated in the calculator installed on the bottom of the upper case 208 is displayed through the liquid crystal 217 installed on the floor surface of each of the sand containers 204a and 204b.
  • a liquid crystal 127 hidden by the sand in one sand container 204a or 204b becomes visible allowing the user to see time and a date while a liquid crystal 127 displaying the time and date in the other sand container 204b or 204a is hidden.
  • the liquid crystal 217 installed at the upper case 208 can always show time and a date.
  • a crown may be used as the switch, and the present invention is not restricted thereto.
  • the present invention allows a sandglass to be wearable around the wrist, thereby providing convenience in use and carrying along.
  • ornamental features can be added to the simple function of a sandglass.

Abstract

Sablier pouvant être porté au poignet et comprenant un boîtier intérieur contenant deux réservoirs à sable accouplés de façon symétrique par l'intermédiaire d'un élément de liaison pourvu d'une ouverture permettant à ces deux réservoirs de communiquer l'un avec l'autre. La surface de ces deux réservoirs est constituée par un matériau transparent. Ce sablier possède également un boîtier extérieur comprenant un espace intérieur de dimension prédéterminée afin de pouvoir loger le boîtier intérieur, un bord de ce boîtier extérieur étant retourné vers l'intérieur afin de retenir un bord du boîtier intérieur logeant dans l'espace intérieur, des éléments de montre étant placés dans des positions prédéterminées respectives sur un côté du diamètre extérieur du boîtier extérieur. Etant donné que ce sablier se porte autour du poignet, il peut être utilisé immédiatement. On peut sélectionner le sable contenu dans les réservoirs dans différents types de sable, ce qui confère une dimension esthétique à l'ensemble.
