Abstract
A handless timepiece such as a clock or watch having a time indicator mounted on a driven belt of finite length driven by two rolls and wherein the time symbols are arranged in a preset sequence of the belt, and are caused to pass between these rolls in front of an indicator window, and wherein the belt drive is designed so that the belt is alternatively taken up from one roll to the next. The time symbol sequence on the minute belt is "00 59 01 58 02 57 03 . . . 33 27 32 28 31 29 30" and the time symbol sequence on the hour belt is "0 23 1 22 2 21 3 . . . 15 9 14 10 13 11 12", and wherein every second symbol appears in the indicator window. The present handless clock or watch avoids rewind of the belt and the concomitant lost time ocasioned by such rewind.
Claims10
A handless timepiece comprising time indication means situated on at least one finite, driven belt, said time indication means comprising symbols arranged on said belt in a preset sequence and in which the belt is wound up on two rolls and said symbols caused to pass between said rolls at an indicator window of the timepiece, and the belt drive comprising a motor driving the belt by said rollers so that the belt is alternatively taken up from one roll to the other one and remains stationary whenever the particular symbol to be indicated is situated behind the indicator window, further characterized in that the belt controlled by one of two stop-contacts stops and remains stationary only the moment each second symbol of said symbols appears behind the indicator window characterized in that a switch means is actuated at the respective end of the belt for reversing the direction of rotation of said drive motor to drive the belt, further characterized in that control pulses are generated by a vibrator quartz having a series-connected frequency divider, said frequency divider transmits said pulses via a transistorized driver stage to said switch means for the direction of rotation of said drive motor, said driver stage being connected to a selector switch within said switch means connecting in each give direction of rotation one of said two stop-contacts to the driver stage to control the drive motor.
A handless timepiece comprising a finite belt having minute time symbols thereon in the following preset sequence, "00 59 01 58 02 57 03 . . . 33 27 32 31 29 30", and means comprising a motor to drive said belt in one direction so that each second symbol sequentially appears in a time indicator window and means to reverse the direction of said belt drive upon completion of the last symbol, so that each second symbol in reverse sequence then appears in said time indicator window characterized in that said reverse means comprises a switch means which is actuated at the respective end of the belt for reversing the direction of rotation of said motor to drive the belt, further characterized in that control pulses are generated by a vibrator quartz having a series-connected frequency divider and said frequency divider transmits said pulses via a transistorized driver stage to said switch means for the direction of rotation of the drive motor, said driver stage being connected to a selector switch within said switch means connecting in each given direction of rotation one of two-stop contacts to the driver stage to control the drive motor.
