Definitions
- the invention relates to a rotary knob with two actuating functions Turning and pressing according to the preamble of claim 1.
- Such an operation is such. B. that of an operating mode selector switch.
- knobs are known, for. B. in car radios where the volume is regulated by turning a rotary knob, whereas by Pressing the rotary button starts a station search.
- EP 0 050 208 A1 discloses a generic rotary knob in which various functions can be selected by turning them into defined positions.
- the rotary knob has an axis of rotation mounted on a printed circuit board with conductor tracks and two rigid contact levers which can be rotated about this axis of rotation and which are connected to the Interconnect conductor tracks on the circuit board.
- By selecting one of the Functions by turning the rotary knob becomes immediate and simultaneous an adjustment function z. B. on a device with a time display by automatic Generating pulses executed.
- the counting direction of this adjustment function can be reversed by pressing the push button.
- From DE 31 32 731 A1 is a rotary knob with two actuating functions Known turning and pushing, whereby by turning into defined positions different Functions can be preselected and when pressed in the selected position an electrical contact is closed.
- the basic idea of the invention is with a rotary knob in its Normal position by turning into several defined positions, multiple functions on a device, especially a stove timer.
- the rotary knob In the selected Position, the rotary knob can be pressed and releases an adjustment function there by generating pulses for the selected function.
- a corresponding adjustment to a time display In this way are a cooking time on a stove timer in addition to the time of day setting End of cooking time or start of cooking time and a short time can be set. All of these Common to functions is that they require a time setting.
- the Adjustment function z. B. makes a temperature setting. It is important that at the adjustment function the size of the adjustment is visible on the display.
- a knob (1) is shown, which Outputs (2) and (3).
- the output (3) is connected to a switch (5), which can connect a pulse generator (6) to a display memory (7).
- the latter is upstream of a display, digital or analog.
- the knob (1) is according to Figure 2 with its housing (10) on a circuit board (11) stored.
- a displaceably mounted switch axis is located in the housing (10) (12) provided against the force of a spring (13) in the drawing down is movable.
- a bore (14) the shaft of the operating button - not shown - be stored.
- the switch axis (12) is prevented from falling out by a resilient part (10a) the circuit board (11) secured.
- a safety hook on the switch axis (12) (15) provided which - in the preassembled state, i.e. H. before snapping in the printed circuit board - a contact plate (17) at which it is pressed out the spring (13) prevents.
- a rib (16) is also injection molded onto the switch axis (12), which serves to deflect the contact disk (17). This contact disc (17) is secured against rotation on the switch axis (12), but can be tilted.
- a detent (23) is provided on the switch axis (12), which with a spring-formed part (10a) of the housing (10) cooperates.
- the circuit board (11) with the conductor tracks (20, 21 and 23) is shown
- the actually opaque contact disk (17) is the better one in FIG Recognizable because of transparent, to look at the one below it free conductor tracks and the corresponding contacts.
- the contact disc (17) lies with its contact (18) on the innermost conductor track (20).
- the conductor track pieces (23) are from a contact (24) when turning the Painted contact disc (17).
- This contact (24) is in Figures 2 and 3, because it lies behind the switch axis (12), not recognizable.
- the conductor track (20) is the central conductor track connected to a pole of the power source, the Conductor (23) serves, due to its segmentation, for the selection of the functions, d. h Each of these segments is assigned to a different function of the device.
- the conductor track (21) is assigned to the adjustment function and triggers indifferently wherever the contact (19) comes to rest on this conductor path, always the same impulse from the pulse generator (6).
