Abstract
Description
Oppfinnelsen angår en trykktast for et tastatur anordnet i et apparat innen elektrisk telekommunikasjonsteknikk, særlig et betjeningsapparat for en telefoninnretning, hvor trykktasten er innsatt i en åpning i apparatets kapsel og via en tapp kan trykkes mot en i det indre av kapselen anordnet tast for å betjene denne og har forspente, i sideretningen anordnede fjærelementer som er utstrakt i lengderetningen og ligger an mot en anslagsflate inne i kapselen. The invention relates to a push button for a keyboard arranged in a device within electrical telecommunications technology, in particular an operating device for a telephone device, where the push button is inserted in an opening in the capsule of the device and via a pin can be pressed against a key arranged in the interior of the capsule to operate this and has pre-tensioned, laterally arranged spring elements which are extended in the longitudinal direction and rest against a stop surface inside the capsule.
Telefoninnretninger behøver for oppsetning av samtaleforbindel-ser betjeningsapparater med valginnretninger som for det meste er forsynt med dreibar nummerskive. Men der finnes også innretninger, særlig automattelefon-innretninger, til formålet, hvor betjeningsapparatene er forsynt med valgtastaturer, hvorved valgoperasjonen vesentlig lettes. Tastaturene er i dette tilfelle forsynt med som regel trykte sifre eller symboler svarende til sin funksjon. For setting up call connections, telephone devices require operating devices with selection devices which are mostly equipped with a rotatable number dial. But there are also devices, especially automatic telephone devices, for the purpose, where the operating devices are equipped with selection keyboards, whereby the selection operation is significantly facilitated. In this case, the keyboards are usually provided with printed numbers or symbols corresponding to their function.
Betjeningsapparatet for en telefoninnretning kan enten være en separat innretning med tilhørende telefonrør, slik det i alminnelighet er tilfellet, eller også være en mikrotelefon som valg- og indikatorenhetene er integrert i. I begge tilfeller behøves tastaturer som betjenes ved hjelp av trykktaster innsatt i åpninger i kapselen. The operating apparatus for a telephone device can either be a separate device with an associated telephone receiver, as is generally the case, or be a handset in which the selection and indicator units are integrated. In both cases, keyboards are needed which are operated by means of push buttons inserted in openings in the capsule.
Fra DE-A-3 112 328 er det kjent en trykkbryter med en hettefor-met trykktast som i alt vesentlig tilsvarer den i innledningen omtalte trykktast. I den forbindelse er det ved den nedre kant av trykktasten dannet en rekke, om omkretsen jevnt fordelte elastiske fjærtunger som tilbakestillingsfjærer fra hver av hvilke et parti rager ut over den nedre kant av trykktasten i betjeningsretnlngen og støtter seg nedad mot bryterhuset. Fjærtungen fjærer ved betjening av trykktasten tilbake i en forekommende uttagning i trykktasten. From DE-A-3 112 328, a push switch with a cap-shaped push button is known which essentially corresponds to the push button mentioned in the introduction. In this connection, at the lower edge of the push-button, a series of elastic spring tongues evenly distributed around the circumference are formed as reset springs from each of which a part protrudes over the lower edge of the push-button in the direction of operation and rests downwards against the switch housing. When the push button is operated, the spring tongue springs back into a recess in the push button.
Til grunn for oppfinnelsen ligger den oppgave å skaffe en stabil og funksjonssikker føring for slike trykktaster i kapselen og sikre at sifrene og symboler er godt identifiser- The invention is based on the task of providing a stable and functionally reliable guide for such push buttons in the capsule and ensuring that the numbers and symbols are easily identifiable.
bare resp. leselige ved forskjellige lysforhold. only resp. legible in different lighting conditions.
Denne oppgave blir løst ved at trykktasten har en nedad åpen, halvskallformet tasthette av rektangulær form som kan innsettes i kapselens åpning med spill i sideretningen, og ved minst én side som strekker seg parallelt til åpningen i kapselen, et forspent fjærélemerit som skråner mot kapselen med en spiss vinkel og rager forbi den halvskallformede tasthette på siden og støttes mot en anslagsflate i kapselen og ligger an mot innsiden av kapselveggen med oversiden av anslagsflåtene dannet av fjærelementene, idet anslagsflåtene har en øket diameter relativt til kapselåpningen og rager ut i sideretnin-" gen, og eri gjennomsiktig plastdel som fyller tasthettens innvendige rom og har en aksial tapp, at tasthetten dessuten' har en avtrapping på oversiden, og at trykktasten i sin midtre, forhøyde del er forsynt med en .utsparing med ét tali- eller ■ symbol som består av den gjennomsiktige plastdel og via denné gjennomsiktige plastdel som fyller det innvendige rom i den opake halvskallformede tasthette, på i og for seg kjent måte er lysledende forbundet med den på denne gjennomsiktige plastdel anbragte tapp. This task is solved by the push button having a downwardly open, semi-shell-shaped key cap of rectangular shape which can be inserted into the opening of the capsule with play in the lateral direction, and on at least one side which extends parallel to the opening in the capsule, a pre-stressed spring element which slopes towards the capsule with an acute angle and projects past the half-shell-shaped keycap on the side and is supported against a stop surface in the capsule and rests against the inside of the capsule wall with the upper side of the stop fins formed by the spring elements, the stop fins having an increased diameter relative to the capsule opening and projecting in the lateral direction , and a transparent plastic part that fills the keycap's interior space and has an axial pin, that the keycap also has a step on the upper side, and that the pushbutton in its central, raised part is provided with a recess with one tali or ■ symbol which consists of of the transparent plastic part and via this transparent plastic part that fills the internal space in the opaque half-shell-shaped keycap, in a manner known in and of itself, is light-conductingly connected to the pin placed on this transparent plastic part.
Gunstige utforminger og videre utviklinger' av oppfinhel-sesgjenstanden er angitt i de uselvstendige krav! Beneficial designs and further developments' of the invention are indicated in the independent claims!
I det følgende vil oppfinnelsen bli belyst nærmere ved et utførelseseksempel som er vist på tegningen. Fig. 1-4 viser "en trykktast henholdsvis i sideriss, i enderiss, i grunnriss og i snitt etter linjen IV-IV på fig. 3. In the following, the invention will be explained in more detail by means of an embodiment shown in the drawing. Fig. 1-4 show "a push button respectively in side view, in end view, in plan view and in section along the line IV-IV in Fig. 3.
Fig. 5 viser en trykktast innbygget. Fig. 5 shows a built-in push button.
Trykktasten 1 består av en mot undersiden åpen, skålformet del av rektangulær form, på hvis langsider og kortsider der er anbragt fortrinnsvis sprøytestøpte fjærelementer 2. Disse fjærelementer 2 er festet ved hjørnene av trykktasten 1 og forløper i en spiss vinkel i forhold til horisontalplanet i retning nedover, altså mot kapselen 6, som de settes inn i. På oversiden er trykktasten 1 utført trappeformet, og dens midtre, høyeste del som utgjør en tasthette 3, forsynt med en uttagning som tilsvarer sifferet eller symbolet som trykkflaten 1 skal. identifiseres med. Sifrene resp. symbolene består av et lysgjennomtrengelig plast. De er via plastdelen 4, som fyller ut det indre rom av tasthetten 3 av lys-ugjennomtrengelig plast og sitter fast i denne, lysledende forbundet med en tapp 5 på plastdelen 4. Til formålet benyttes et lyssamlende, fluorescerende innfarvet plastmateriale som forener de gunstige egenskaper at det både er godt leselig i dagslys og også om natten kan belyses tilstrekkelig innenfra og dermed likeledes bli leselig. The push button 1 consists of a bowl-shaped part of rectangular shape, open towards the underside, on the long sides and short sides of which preferably injection-molded spring elements 2 are placed. These spring elements 2 are fixed at the corners of the push button 1 and run at an acute angle in relation to the horizontal plane in the direction downwards, i.e. towards the capsule 6, into which they are inserted. On the upper side, the push button 1 is designed in the form of a staircase, and its middle, highest part, which forms a key cap 3, is provided with a recess that corresponds to the number or symbol that the push surface 1 is to. be identified with. The figures or the symbols consist of a translucent plastic. They are via the plastic part 4, which fills the inner space of the keycap 3 of light-impermeable plastic and is fixed in this, light-conductingly connected to a pin 5 on the plastic part 4. For this purpose, a light-gathering, fluorescent colored plastic material is used which combines the favorable properties that it is both well readable in daylight and also at night can be sufficiently lit from within and thus also be readable.
Fig. 5 viser den omtalte trykktast 1 i innbygget tilstand. Flere trykktaster er hensiktsmessig anbragt i et raster og forsynt med symboler svarende til sin funksjon. De tilhørende taster 8 er anbragt i samme raster, f.eks. på en lederplate 10 og i det viste eksempel innloddet via loddetilslutninger 9. Fig. 5 shows the discussed push button 1 in the built-in state. Several push buttons are suitably arranged in a grid and provided with symbols corresponding to their function. The associated keys 8 are arranged in the same grid, e.g. on a conductor plate 10 and in the example shown soldered in via solder connections 9.
Trykktasten 1 er innsatt i en åpning i en kapsel 6. Den har her sidelengs klaring, så den ikke kan kile seg fast. Med oversiden av de ved kantene av fastsittende fjærelementer 2 ligger trykktasten 1 an mot kapselens innervegg. Fjærelementene 2 har støtte på en anslagsflate dannet av en lysleder 7 som har en motsvarende boring til å oppta tappen 5 på trykktasten 1. Lyslederen 7 tjener til tilførsel av lys til sifrene resp. symbolene i trykktasten 1. The push button 1 is inserted into an opening in a capsule 6. Here, it has lateral clearance, so that it cannot wedge itself. With the upper side of those at the edges of fixed spring elements 2, the push button 1 rests against the inner wall of the capsule. The spring elements 2 are supported on a contact surface formed by a light guide 7 which has a corresponding bore to accommodate the pin 5 on the push button 1. The light guide 7 serves to supply light to the digits or the symbols in pushbutton 1.
For betjening blir trykktasten 2 med sin tapp 5 trykket mot tasten 8 og deretter skjøvet tilbake av - de i utførelseseksem-pelet fire - fjærelementene 2 som sitter fast på sidene av trykktasten 1. Med disse fjærelementer 2, som består av et passende elastisk plastmateriale, er det også sikret at trykktastene ikke klaprer i kapselen og forårsaker uheldig støy under kjøring. For montasjen betyr de integrerte fjærelementer en vensentlig forenkling. At der ikke forekommer noen separat fjær, medfører foruten forenklet oppbygning også en minskning For operation, the push button 2 with its pin 5 is pressed against the button 8 and then pushed back by - the four in the design example - the spring elements 2 which are attached to the sides of the push button 1. With these spring elements 2, which consist of a suitable elastic plastic material, it is also ensured that the push buttons do not rattle in the capsule and cause unpleasant noise while driving. For assembly, the integrated spring elements mean a considerable simplification. The fact that there is no separate spring, in addition to a simplified structure, also results in a reduction
