Definitions
- the invention relates to a watch according to the preamble of claim 1.
- Such a watch is described in DE-GM 8 717549 and in various models of the applicant which have emerged from it on the market.
- manual setting processes which is usually the setting of an alarm time, but it can also be a time zone shift of the time display
- such clocks are equipped with three switches as standard.
- One of these is an electronic or mechanical changeover switch, with which the register for the time information presented is temporarily set out of the operating state into the SET or setting mode, in which pulses individually or as internal - preferably - via the two other switches with a step-by-step pulse repetition frequency - generated pulse sequences can be added additively or subtractively to the previous register content.
- the SET function for example, the wake-up time previously specified and presented in the time range of the display device can be changed or the entire time display of the watch can be continued to another time zone.
- the invention is therefore based on the technical problem of equipping a generic watch in such a way that it is not only safer to use but also less expensive to manufacture.
- the separate SET switch is dispensed with and the operating mode is switched from the operating to the setting mode via the two remaining setting switches themselves, by temporarily operating these two switches simultaneously for the transition to the setting mode. It can then be provided that one of the two pushbutton switches is held and the other is used to enter the pulses to be accumulated in the register; or the two pushbuttons are operated individually after reaching the SET mode, depending on whether the accumulation of the register contents is to take place upwards or downwards. If neither of the two pushbuttons has been pressed for a specified period of time, the system automatically switches back from SET to operating mode.
- the timing can be prepared by simultaneously pressing both setting buttons and then carried out by pressing a button.
- the current time display of a clock can also be changed in the same way. If this is a radio-controlled clock that does not need to be set manually, the time zone can be adjusted by double-clicking to switch the operating mode and then by using the individual button.
- the queries regarding the presence of the logical (button actuation) conditions can be made by gate circuits. It is more expedient since it is more economical to implement decision logic within a processor, which is present in any case in a radio-controlled clock anyway, in order to verify the demodulated time telegrams and, if necessary, to correct the current time display thereon, as explained in more detail in US Pat. No. 4,645,357.
- Electrode comb structures for the pushbutton switch paths are preferably in a part of the circuit board next to a display that protrudes from the actual work capsule.
- the display can be arranged at a comparatively large distance from the analog display, and in its surroundings there is sufficient space on this circuit board for the formation of large-area electrode comb structures.
- the buttons that can be used to press switch rubber pads directly onto the comb structures or via bellcranks can be positioned relatively freely (according to the design specifications) over the printed circuit board.
- a receiving area for the termination of electronic and electromechanical components for realizing additional functions can be prepared on this part of the printed circuit board protruding from the work capsule.
- the front cover of the work capsule itself is also provided or prepared to directly accommodate the display and the push button switches; for which the part of the circuit board protruding from the work capsule is then omitted or can be subsequently separated along predetermined breaking points in a defined manner.
- the clock 10 sketched in front view and to a certain extent with no top wall is preferably an alarm clock and again preferably a radio-controlled alarm clock. It can be a purely digitally displaying clock 10 or, as shown, one with an analog-digital hybrid display. In this case, the hands 11 move in front of a dial 12, while a digital display device 14 can be switched between derived time information, among which a calendar can be given and in the case of an alarm clock 10 is in any case an alarm time. This area 13 of the display device 14 can thus be switched over manually or automatically for presentation z. B. the current date (by month and day) or other information (as well as temporarily the current hour, namely during rapid traverse of the pointer 11 due to radio-controlled synchronization of the time display and / or due to radio-controlled or manually triggered time zone change).
- a separate information area 15 is provided, in which - controlled by an electronic switching device 16 - an alarm transmitter symbol 17 is continuously displayed when the alarm signaling circuit is ready for operation, but is displayed flashing when the alarm signaling circuit is in the setting mode described in more detail below but is completely switched off when the alarm circuit is out of operation (switched off).
- the information area 15 also contains a digital reception display 19, which indicates in terms of numbers how often since the most recent radio-controlled display synchronization the receiver 21 has been switched on (manually or time-controlled) without the reception of time telegrams which can be used for the synchronization .
- the temporary switching on of the receiver 21 always leads to the reception of usable time telegrams, so that normally the reception display 19 shows the value "zero-zero" - if not this normal state display to avoid any irritation, the reception display 19 is only visible when the display values are greater than zero.
- a switching register 16 the current content of which is presented in the time area 13 of the display device 14, is thus set via the switchover device 16 ready for recording for pulse inputs for positive or negative incremental advancement of the register content (observable in the time area 13).
- the display in area 13 is a normal time indication in the case of an autonomously operated, digitally displaying clock, for example from a quartz-stabilized clock circuit, in which manual time correction or time zone changeover can take place; or in the display register 24 the alarm time specification is stored, which is compared via a comparator 25 with the time register 26 (which can be corrected via the receiver 21 of a radio clock 10) for the current current time in order to provide an optical and / or acoustic signal in the event of a coincidence Control signal generator 27.
- a motor 28 for moving the hands 11 via a gear 29 is controlled from the time register 26 if, as shown, it is a clock 10 with an analog time display on a dial 12.
- the (stepping) motor 28 is arranged and operated intermittently with respect to the magnetic antenna 29 feeding the receiver 21 in such a way that, according to DE-GM 90 10 813, practically no disturbing electromagnetic effects from motor operation on the function of the receiver input circuit occur.
- the display register 24 is thereby enabled (via the electronic switching device 16) to receive indexing pulses, the currently accumulated counting result of which is displayed in the time range 13, in that both actuating key switches 18 and 20 are actuated simultaneously, which is done via the AND link 23 of the switching device 16 is detected.
- a holding circuit 30 can then be provided in the switching device 16, which keeps the input option open as long as one of the switches 18 or 20 remains actuated, while the other is keyed for counting up or for counting down small display units (for example minutes). If neither of the two pushbutton switches 18, 20 is actuated, the hold circuit drops out again.
- the holding circuit 30 be equipped with a downshift delay. Then it is sufficient to set the display register 24 ready for recording via the AND link 23 and the holding circuit 30 by actuating the two push buttons 18, 20 overlapping in time; whereupon only either the pushbutton switch 18 for the upward direction or the pushbutton switch 20 for the downward direction of the accumulating counting process in the register 24 is actuated and no other pushbutton needs to be held manually for this now.
- the holding circuit 30 blocks the possibility of input into the display register 24 again if no button actuation has taken place for a period of time specified in terms of circuitry or program technology, approximately ten seconds after the last actuation of one of the button switches 18 or 20.
- the display 14 shows the current operating state again. This means that a date is displayed in time range 13 when the alarm function is switched off. It is turned on by not pressing both pushbuttons 18, 20 simultaneously, but either only the pushbutton switch 18 or only the pushbutton switch 20 being operated continuously for a minimum period of time (for example for more than three seconds), with the result that the alarm symbol 17 now appears. In this operating state, one of the two pushbuttons 18 or 20 can again be used to switch the presentation in the time range 13 between the current date and the alarm time currently entered by briefly (in the example, remaining under three seconds).
- this brief actuation optionally causes only one of the two pushbuttons 18 or 20 that the alarm signal is switched off, but that the alarm is ready again after 24 hours (which is indicated by the alarm symbol 17 continuing) .
- a single pushbutton operation over a longer period of time in any case has the consequence that a switch is made from the current alarm readiness, that is, from the OFF state to the ON state or vice versa; in the OFF state, the presentation of the alarm symbol 17 in the information area 15 of the display device 14 disappears and the time area 13 switches to the presentation of the date.
- an alarm clock 10 of the type considered here also has a snooze button 31. If this is actuated when the predetermined alarm time is reached, i.e. while the alarm signal is being emitted, the result is that the alarm signal is temporarily suppressed and only after a certain time Time period of a few minutes is released again (function of the alarm signal repetition). In addition, provision can be made to switch on temporary dial lighting.
- the holding circuit 30 ends the SET mode again if no actuation of one of the key switches 18, 20 has taken place over a predetermined period of time.
- the content of the time register 26 has thus been moved to another time zone with the correct timing.
- a multiple revolution of the minute hand corresponding to the time zone shift takes a certain amount of time. Therefore, at least the hour currently given in the new time zone is expediently displayed in the time range 13. The switches back to the date or the alarm time when the hands 11 have turned to the angular position corresponding to the new time zone.
- 2/3 is preferably also one for an alarm clock 110 and again preferably one for a radio-controlled alarm clock 110 with an analog-digital hybrid display.
- the pointers (not shown in the drawing), carried by shafts 111, move in front of the front cover serving as dial carrier 112 of a work capsule 113, which accommodates the gear train 114 for the timed drive of the pointer train 115 with its pointer shafts 111.
- the latter include a time-keeping circuit 118 for driving the gear train 114 and, in the case of a radio clock movement 110, its radio clock circuit 119 (with a long-wave receiver, demodulator and processor for controlling the receiver activation and for checking and, if necessary, correcting the pointer position) together with a ferrite loop antenna 120 for the supply of the long-wave receiver in the radio clock circuit 119 and at least one light barrier 121 for pointer position detection via diaphragm holes which are formed in the wheel and pointer mechanism 114/115 (opposite a reflector 122 on the inside of the housing rear wall 123); such as described in more detail in U.S. Patent 4,645,357.
- the clockwork for this clock 110 is only partially encapsulated insofar as the work capsule 113 only accommodates part of the printed circuit board 117. Otherwise, this protrudes parallel to the dial carrier 112 from a side wall 124, preferably downward from the lower side wall 124.
- This part 117 'of the printed circuit board 117 protruding from the work capsule 113 carries an electro-optical display 125 for digital additional displays such as, in particular, calendar and alarm information, directly or via a plug-in base.
- very large-area electrode comb structures 126 located on both narrow sides next to the display 125 are formed on the protruding part 117 'of the printed circuit board 117 the conductive rubber, for example stored in the watch case, can be pressed on by pressing a button to establish a potential connection, which is connected to the internal time keeping and time telegram detection.
- Control circuit 127 for the display 125 is evaluated as a manual switchover or information input.
- a key operation can be provided in combination with the operation of an alarm signal canceler 131, which engages in the work capsule 113 at the top.
- the comb structures 126 which can be short-circuited in pairs, are larger in area than would be required for the button function in order to be variable in terms of design in the local button arrangement next to the display 125.
- the protruding part 117 'of the printed circuit board 117 it may be expedient to design the protruding part 117 'of the printed circuit board 117 so large that between the clock case 113 and the display 125 there is still a receiving area 128 for mechanical mounting and electrical connection of further electronic or electromechanical components for implementation of additional functions is available. If this option is not required, the display 125 (with the comb structures 126 lying on the narrow side) can also be moved closer to the outlet side wall 124 (contrary to the drawing) and the protruding circuit board part 117 'can be shortened accordingly.
- predetermined breaking points 129 can be formed in the area of the passage side wall 124 in order to be able to separate the protruding part 117 ′ in a simple and defined manner if, in the interest of a small-sized watch, the dimensions of the work capsule 113 should not be exceeded or the work capsule 113 itself serves as a watch case.
- cutouts 30 are provided or can be exposed in the front wall of the work capsule 113, which serves as the dial carrier 112, in order to be able to arrange the display 125 and the push-button switches above the electrode comb structures 126 within the work capsule 113 even if the work capsule 113 does not tolerate any outstanding printed circuit board part 117 '.
