Definitions

  • the invention relates to a set of buttons for actuating the contact of an electronic device, in particular a video recorder, the set of buttons consisting of a plurality of individual buttons which are made in one piece from plastic and connected to the device housing or to the device chassis by means of a carrier, and the buttons preferably via a contact plunger on individual Apply pressure switches arranged in series on a pressure plate.
  • key sets which have a closed structure and are used as a complete key set on a device chassis or in a device housing. Although these key sets are of universal use, they are complex and not sufficiently flexible with regard to the design of the key button shape. Furthermore, key sets are known, the individual parts of which are assembled into a key set only when the device is being assembled. Here, the device housing preferably takes over the leadership of the button.
  • a push button arrangement in which several push buttons molded in one piece from plastic are used.
  • the individual push buttons consist of a button and a contact plunger extending in the extension of the button.
  • the end of the contact plunger presses on contacts which are arranged on a printed circuit board perpendicular to the longitudinal axis of the pushbuttons.
  • Each push button is connected by two webs to a connection carrier which has holes for fastening the entire set of buttons to the push button arrangement or the housing.
  • a push button When a push button is pressed, it describes a circular path and thus tilts to its longitudinal axis in the unactuated state.
  • the pushbuttons must therefore be designed conically, otherwise touching and possible friction with the button guide can occur while they are being pressed down. Due to the conicity of the pushbuttons, the guidance of the buttons when pressed is no longer guaranteed.
  • the object of the invention is therefore to provide a simple set of buttons in the device, which consists of a few parts and is to be installed in the device as automatically as possible, the key guidance of the individual key buttons being largely independent of the guidance provided by the key cutout in the housing.
  • FIG. 1 The simplified drawing of FIG. 1 essentially shows a button set 1 in section, which is inserted in a housing 2 of an electronic device.
  • the key set here consists of several keys arranged in a row, only one key 3 being shown enlarged in the figure shown.
  • the individual key itself has a key button 4, which is extended by a contact plunger 5.
  • a short guide bar 6 is attached parallel to the contact plunger.
  • Each key is connected to a carrier 8 via a web 7 which is inclined at approximately 45 ° -60 ° to the key actuation line - in the example shown approximately 55 °. It is essential here that the web 7 on both connection sides made of plastic with all other key parts integrally molded film hinges 9 and 9 '.
  • the key 3 is connected to the housing 2 via the carrier 8.
  • a pressure plate 10 is inserted perpendicular to the direction of actuation of the button 3 in the housing 2 and held by this.
  • a contact plunger is assigned in series and in each case on the pressure plate, at least one pressure switch 11 is attached and soldered to the pressure plate.
  • the button 3 If the button 3 is now pressed, the position of the film hinges 9, 9 'give the button an almost vertical movement in the direction of the pressure switch 11, and the button can move smoothly relative to the cutout provided in the housing 2.
  • the individual button to distinguish different device functions that can be operated via the respective button can have a different key width.
  • the button is preferably connected to the carrier 8 by two webs 7 arranged in parallel.

Claims (3)

  1. Clavier servant à l'actionnement des contacts d'un appareil électronique, notamment d'un enregistreur vidéo, ce clavier étant constitué de plusieurs boutons individuels (3) qui sont réalisés d'une seule pièce en matière plastique et sont fixés sur le boîtier (2) de l'appareil ou sur le châssis de l'appareil en étant réunis par l'intermédiaire d'un support (8), tandis que les boutons agissent, de préférence par l'intermédiaire d'un poussoir de contact, sur des interrupteurs à pression (11) individuels disposés en rangée sur une plaquette à circuits imprimés (10), et que chaque bouton (3) est constitué d'une tête de bouton (4) et d'un poussoir de contact (5) qui s'étend dans le prolongement de la tête de bouton, caractérisé en ce qu'il est prévu une barrette de guidage (6) disposée d'une manière pratiquement parallèle à l'axe longitudinal du poussoir de contact (5) et chaque bouton est relié au support (8), par l'intermédiaire de la barrette de guidage, au moyen d'au moins une barrette (7) disposée à environ 45 à 60° vis-à-vis de la direction d'actionnement du bouton et en ce que, sur ses deux côtés de liaison, la barrette comporte une charnière (9, 9′) de très faible épaisseur qui est venue d'une pièce par injection de matière plastique.
  2. Clavier selon la revendication 1, caractérisé en ce que la zone mince de la charnière (9, 9′) située à l'emplacement de liaison entre la barrette (7) et la barrette de guidage (6) s'étend en longueur en direction de la barrette de guidage et la zone de charnière tournée vers l'emplacement de liaison du support est disposée dans le prolongement de ce support.
  3. Clavier selon l'une des revendications 1 et 2, caractérisé en ce que deux nervures à disposition parallèle remplissent la fonction de liaison par l'intermédiaire des charnières de très faible épaisseur situées entre la barrette de guidage et le support.
