Definitions

  • the invention relates to a key arrangement for triggering certain symbols of the key surface, respectively associated switching functions or switching signals.
  • Key arrangements in the form of key fields or rows of buttons are generally known, in which, for example, a switch contact is assigned to each individual key, which is closed to implement a switching function when the key in question is actuated, or which has a stop signal on one Uses the useful circle as soon as the associated key is pressed.
  • German patent specification 737 039 it is known that the required to generate a certain number of switching functions or switching signals.
  • a digit of the decimal system can be represented in binary coding by optionally pressing individual or joint keys of the group of four.
  • the structure of the known key arrangement is complicated and unsuitable for the production of longer rows of keys or larger key fields.
  • the invention is intended to achieve the object of designing a key arrangement of the type briefly mentioned at the outset in such a way that a sufficiently large surface located in a single plane for key labeling is available within a limited area and the finger of an operating hand has a large operating surface for depressing the key surface assigned to a specific symbol. .
  • This object is achieved in that progressively from key to key in a row of keys, the output positioning movement signals each of pairs of adjacent, together the labeling field for each symbol assigned and depressable together by a finger keys of an AND link to form the switching function mentioned or the switching signal mentioned.
  • Another solution according to the invention provides that progressively from key to key in a keypad, the output positioning movement signals of at least two diagonally opposite keys of a group of four, together with the labeling field for one symbol each, and which can be depressed together by a finger, for an AND link Formation of the switching function or the switching signal mentioned.
  • the output actuating movement signals are preferably used only from every second of each key row and each key column to derive the switching function or the switching signal.
  • the output actuating movement signals of a mask group to be subjected to an AND linkage can be coupled to a mechanical AND switching element, the mechanical AND switching element in each case being switched from one to the other tying output actuating movement signals delivering buttons in the direction of the rest position coupled switching pin is formed, by means of which the switching function or the switching signal can be generated and which is biased towards the actuating position with a force which is less than one each biasing the buttons in the rest position Force is such that the biasing force of the switching pin is only able to pull it into the actuation position when all of the keys of the relevant key group are actuated.
  • Switching means are preferably assigned to each of the individual keys providing an output actuating movement signal, from which signals can be removed when a key is actuated, which signals are each subjected to the AND link mentioned.
  • Each of these labeling fields takes up a part of the key surface of four keys each in a square arrangement, which represent a key group.
  • the labeling fields b 1 to b 4 are thus divided crosswise by the column located between the keys of a key group.
  • the mechanical transmission means 2 and 4 effect the first key of the second key line and the first key of the second key column include that the respective upper contacts of the contact sets 6 and 8 have been closed and the associated signal line is turned on. If the four keys of the keypad 1., which belong to the drilling field b 2, are depressed, the mechanical transfer means 4 and 5 9, which are coupled with the first key of the second key column and the last key to the second key row, close the lower contact of the contact set 8 and the upper contact of the contact set 9, so that the associated Signal line establishes a lead connection.
  • the meohanisoh transmission means 2 and 3 cause i closing of the lower IContalctes of the contact set 6 and the upper contact due to the pressing of the first key of the second key row and the last key of the second key column of the contact set 7, so that the signal line 3 becomes continuous.
  • pressing the buttons belonging to the label fold b 4 leads to one. Closure of the lower contact of the contact sets 7 and 9 and thus a line holding the signal line 4.
  • those keys to which the mechanical transmission means 2 to 5 are connected are marked with a dot on the surface of the key.
  • the surface of the key that presents the fingertip of a confirmation hand I is the one for an inscription field, j for example the lettering field b 4 .
  • associated keys with the upper surface of a single key of a keypad of a known type, because of the encoding of the output positioning movement signals, as far as there is room for movement of the actuating finger, within which no Felil actuation can occur.
  • the AND combination of the output actuation signaling of the keys of a key group enables certain parts of the key surface, which is also assigned to a neighboring symbol, to be used at the same time as an effective actuation area for a specific symbol. With no loss of operating safety, this means that, with a small keypad for only Yier symbols, the required surface of the entire arrangement of keys is reduced by a factor of 9/16, although this value is nooh considerably cheaper for larger numbers of symbols.
  • FIG. 2c shows a keypad with sixteen keys in a square arrangement of four rows and four columns.
  • This conventional keypad has symbols assigned to the symbols 1 to 16, so that a total of sixteen switching elements are required for emitting signals corresponding to the individual symbols.
  • FIGS. 2c and 2d the part of the signal lines running under the keypad is indicated by a broken line.
  • a comparison of FIGS. 2c and 2d shows on the one hand the reduction in the tree requirement with the same operating safety and the possible saving of switching elements with the same number of symbols in each case, the additional effort caused by the decoding device not being particularly important in the case of electronic designs of this part.
  • Each of the switching pins is provided with a head 11, which is accommodated in a recess at the joint of the keys of a key group.
  • the stop pin has a switch which extends through a bore provided along the butt joint of the keys of a key group.
  • a tension spring 12 engages, which tries to pull the switching pin 10 downward against the force of compression springs 13, which in turn bias the aluminum keys upwards into the rest position.
  • the tensile force exerted by the spring 12 is less than the tensile force of each of the compression springs 13, so that the switching pin 10 can be pulled downwards into the actuating position when all of the keys belonging to a key group or a labeling field see below be pushed down.
  • the head 11 of the stylus pen 10 can also be accommodated within the keys in a provision or chamber provided in this, so that the labeling surfaces are each closed except for the column between the individual keys.
  • Din 4 corresponds essentially to that of FIG. 1, with the stop contacts, which produce the pre-connections in the course of the signal lines 1 to 4, being represented by a blook symbol and denoted by the reference number 16.
  • Lead to the contact sets again the mechanical transmission means 2 to 5, which are coupled to those of the keys of the keypad 1, which have a dot on the key surface to clarify the representation.
  • FIG. 4 shows a keypad enlarged in the direction of the key columns, which is shown broken away in order to make it clear that the ideas shown here can be applied to keypads of any size.
  • driver pins 17 similar to the switching pins 10 of the embodiment according to FIG. 3 between the joints of the keys belonging to a labeling field.
  • the driver pins 17 are biased downwards by small tension springs 18 while the compression springs 13 bias the individual keys of the keypad 1 in the rest position.
  • the driving pin causes all the keys of a key group to be actuated synchronously and the contact sets to be actuated in an orderly manner via the mechanical transmission means 2 to 5 is coming.
  • the Mit Anlagenatifte 17 are thus effective as a synchronization means.
  • FIGS. 3 and 4 offer the essential advantage over known key arrangements with island keys that on the one hand a considerable size of the labeling field is available for each individual symbol and on the other hand a self-contained operating surface is provided for the operating finger .
