Abstract
A radio-controlled, analog display clockwork has at least two pointers and is driven by an electric driving arrangement. A pointer setting arrangement is provided for the user to bring the pointers of the clockwork to a predetermined position which corresponds to a certain time. Starting from said predetermined pointer position, the control device applies control signals to the driving arrangement, causing the pointers to move more quickly until they have reached a position which corresponds to the instantaneous time.
Claims19
A radio-controlled analog display clockwork with:
- at least two pointers,
- a current source,
- a driving arrangement (24), driving the pointers,
- a mechanical pointer setting arrangement (43, 44, 46) for bringing the pointers into a predetermined starting position, corresponding to a certain time,
- a control device (55) supplying control signals for controlling said driving arrangement,
- a radio receiver arrangement (52), receiving time signals from a time transmitter and passing them on to the control device (55), said current source, said driving arrangement, said control device and said radio receiving arrangement being arranged in one common housing,
- characterized in that
- said mechanical pointer setting arrangement is to be actuated by the user,
- and thereafter the control device applies control signals to the driving arrangement on the basis of said predetermined starting position, resulting in an increased pointer speed, until a pointer position corresponding to the instantaneous time is reached.
A procedure for setting an analog display radio clockwork said clockwork comprising at least two pointers, a current source, a driving arrangement (24), driving the pointers, a mechanical pointer setting arrangement (43, 44, 46) for bringing the pointers into a predetermined starting position, corresponding to a certain time, a control device (55) supplying control signals for controlling said driving arrangement, a radio receiver arrangement (52), receiving time signals from a time transmitter and passing them on to the control device (55), said current source, said driving arrangement, said control device and said radio receiving arrangement being arranged in one common housing, said mechanical pointer setting arrangement is to be actuated by the user, and thereafter the control device applies control signals to the driving arrangement on the basis of said predetermined starting position, resulting in an increased pointer speed, until a pointer position corresponding to the instantaneous time is reached, a second switching arrangement (46) being provided in said clockwork, permitting the user to start the time setting procedure, performing the movement of the pointers from the predetermined starting position to the pointer position corresponding to the instantaneous time, said procedure for setting said analog display radio clockwork being characterized by the following procedure steps:
- stopping the clockwork, such that the pointers do no longer move,
- moving the pointers into a predetermined starting position by a setting wheel (44) to be actuated by the user,
- starting the setting procedure with an electric switching device (46),
- fixing the instantaneous time by evaluating the time signals received from a radio receiver by means of said control device,
- moving the pointers at an increased speed out of said predetermined starting position, counting the number of current impulses, supplied to said driving arrangement for pointer movement,
- comparing the number of impulses emitted with the number of impulses required for reaching the instantaneous time,
- terminating the setting procedure, as soon as the number of impulses has been put out, required for moving the pointers into a position corresponding to the instantaneous time,
- continuation of the normal clockwork operation.
