WIPO Patent Application WO/2005/031474

Kind Code:

A1

Abstract:

A timepiece (1000) comprises a conical body, a conical body lifting means (100) for lifting the conical body supplied to a lower position to an upper position, a rotary wheel (210) provided with a plurality of supports (212) along the outer periphery, the supports being capable of holding the conical body, and an escapement mechanism which intermittently drives the rotary wheel, the conical body lifting means including a driving body (110) provided with a spiral driving surface having a horizontal or inclined axis, and a rotary drive source for rotation-driving the driving body around the axis, the arrangement being such that the conical body is driven by the driving surface through rotation of the driving body to make a parallel motion from lower to upper position, and the conical body lifted to the upper position by the conical body lifting means is supplied to a receiving section disposed in the upper region, whereby the conical body discharged from the receiving section after the rotary wheel has rotated through a predetermined angle is returned to the lower position in the lower region. This makes it possible to provide a novel timepiece construction which ensures an operation using lower driving power than in the prior art, less energy consumption, appreciation-worthy mechanical movements, and suitability as an ingenious timepiece.
