Definitions

  • the invention relates to a watch with an electronically controlled display device, which has one or more display fields for the output of numbers and / or letters (alphanumeric characters). Various alphanumeric characters are displayed by highlighting certain elements from a set of display elements attached to each display field.
  • Clocks with such display devices have been known as so-called digital clocks for years, for example from DE-OS 29 22 621, which describes an electronically controlled clock with digital time display and alarm device, each with a display field for the output of the time and the set alarm time having.
  • Different digits are displayed on the two display fields by so-called seven-segment displays, the display elements of which consist of light-emitting segments, such as fluorescent tubes or light-emitting diodes (LED), or of passive electro-optical segments, such as liquid crystal cells (LCD).
  • a disadvantage of the previously known watches with an electronically controlled alphanumeric display device is that the display device is either fitted inside the watch case and covered with a translucent plate or is at least firmly connected to the watch case. This has the consequence that an exchange or relocation of the display device for the user of the watch is only possible with unreasonable effort.
  • a clock 1 having an electronically controlled display with a display panel 6 and with an input field 5, which has a plurality of input keys, which are not numbered here.
  • the time (here 2o 0 0 o'clock) in hours and minutes, separated by a colon, is displayed on the display panel 11 with the aid of four seven-segment displays.
  • the date here the October 10th
  • an adjustable alarm time here 3:00 am in the morning
  • the display panel 6 can be pivoted according to the invention on the one hand about a horizontal axis A lying below its lower end face, on the other hand it can be lifted in the direction designated by B in FIG. 2 from the watch case 2, since the display panel 6 is not fixed , but is mechanically and electrically connected to the clock 1 by means of a plug connection 16.
  • FIG. 3 This shows a partially broken section from the surroundings of the right cheek 3 of the watch case 2 of FIG.
  • the housing-like part of the connector 16 consists of a strip 17 made of electrically insulating material, in which several electrical contact devices are embedded, the number of which depends on the number of connections required to operate the display panels 11-15.
  • the strip is preferably made of plastic using the injection molding process, the contact devices essentially consisting of a partially slotted metal bushing also being cast in the same operation.
  • Fig. 3 shows such a metal socket 18, which is connected via a soldered at its lower end to a connecting wire 19 with a display driver circuit, not shown here, located within the watch case 2.
  • the connector 16 On the part of the display panel 6, the connector 16 consists of metal pins attached to its lower end face (see metal pin 20 in FIG. 3). With appropriate matching of the diameter of metal pins and metal bushings, a perfect electrical contact is achieved on the one hand, and on the other hand a sufficiently firm mechanical connection between the display panel 6 and the watch case 2 is achieved.
  • the display panel 6 By means of two U-shaped rails 9 and 10 molded onto the bar 16, which grip around the frame 8 of the display panel 6 and act as guide rails, the display panel 6 can be made on the basis of the then clearly defined spatial association between the metal pin and the associated metal bushing can be plugged in easily and quickly.
  • Such removal and reinsertion of the display panel 6 can be of interest to the user of the watch 1, for example, if the display panel is arranged on one side, for example on its front side 7 passive electro-optical display elements and on the other side, in this case its rear side 21, identically arranged has light-emitting display elements, both of which are suitable for outputting the same information offered by the display driver circuit.
  • the display panel 6 By removing, rotating the display panel 6 by 180 degrees around the axis C (see FIG. 2) and reinserting the display panel, the user of the watch 1 can select the type of display elements facing him.
  • By connecting an additional metal pin attached to the display panel 6 and two associated additional metal sockets it can be ensured that only the respective front side of the display panel 6 is in operation.
  • the user of the watch 1 will only switch from the significantly less power-consuming passive electro-optical display by changing the display panel 6 to the light-emitting display if the illuminance in the area around the watch 1 is no longer sufficient Change electro-optical display. In this way, the power consumption of the watch 1 is therefore kept low despite the presence of light-emitting display elements.
  • the display panel 6 is not only easy to separate from the watch case 2, but is also designed to be pivotable, namely by rotating the bar 17 about the axis A (see FIGS. 1 and 3).
  • Different angles between the front 22 of the watch case 2 and the front 7 of the display panel 6 arise from different positions between a plate 23 formed on the bar 17 and a piston axially displaceable in a bore 24 of the right housing cheek 3 25 (see Fig. 3).
  • Both the disk 23 and the piston 31 have an intermeshing spur toothing on their facing surface.
  • the Piston 31 is secured against rotation about its longitudinal axis by means of two lugs 25 and 26 which are molded onto it and which engage in corresponding grooves 27 and 28 of bore 24.
  • a grub screw 32 which runs in a threaded bore of the housing cheek 3, is molded onto the piston and can be rotated by means of a screwdriver or with a coin or the like.
  • the display panel 6 of the clock 1 can therefore be snapped into different, convenient angular positions by the user. If the input field 5 is set back correspondingly with respect to the contour of the front 22 of the watch case 2, the display panel 6 can be pivoted so far that it comes to lie parallel to the input field 5 and also completely covers it, with its rear 21 inside the Contour, the front 22 of the watch case 2 comes to rest (see position 6 'in Fig. 2). This angular position is particularly suitable for packing the watch for shipping or when traveling.
  • the design according to the invention of a display panel mechanically and electrically connected by means of a plug connection to a watch case is not limited to the exemplary embodiment described above.
  • the display board by means of a plug connection between the clock and the display board in order to operate various electro-optical displays depending on the prevailing light conditions.
  • the set of metal pins or metal bushings which is present in duplicate in accordance with the previously described exemplary embodiment, can be used to control a significantly larger number of display elements.
  • the display panel of FIG. 1 can thus be exchanged for a display panel which, in addition to the output of alphanumeric characters, also enables the quasi-analog display of one or more sizes.
  • electro-optical display elements which on the one hand consist of radially arranged, strip-shaped electrodes and the corresponding counter-electrode arrangement and on the other hand consist of the display elements of a seven-segment display.
  • Such a display board which shows quasi-analog hours and minutes and digitally displays the date, can be controlled with relatively few connections (according to DE-OS 28 05 646, for example with 35 connections).
  • the display panel of FIG. 1 can also be exchanged for a display panel, the display elements of which are arranged as a dot matrix, the double set of metal pins and metal bushings being able to be used as in the previous exemplary embodiment.
  • Such dot matrix display elements can then also be used to carry out simple games on the display board which are related to screen games on television sets. The change of the display mode and the start of such games can be carried out using the actuation device which is attached to the input field.
  • the type of plug connection between the display panel and watch case embodiment of the invention consists in the display panel only with a jack plug and an associated strip-side socket, such as in the case of Connection of headphones to HiFi devices are used to connect mechanically with the watch case and with a circuit contained therein.
  • the watch case then only contains the power supply for the watch, while the input field can be attached to the back of the display panel, the front of which has one or more display fields.
  • Such an arrangement has the advantage that the display panel is not only pluggable and pivotable about the axis A, but can also be rotated about the axis C (see FIGS. 1 and 2).
