Abstract

The invention relates to a keycap for a control unit of a telephone device, in which the keyboard is arranged inside the housing and can be pressed by means of a peg connected to the key cap for operation. The keycap, inserted in a housing opening, is provided with one or more pointed spring elements (2) on the side, which run downwards at an acute angle and are supported on a light conductor (7) in whose hole the peg (5) is inserted. Light is directed via the light conductor and peg to the characters and symbols which consist of a light-collecting plastic. Such a keycap is described in more detail in the main patent. The invention proposes a three layer construction of the keycap, the base body (4, 5) provided with the peg consisting of a clear-glass material, onto which a relatively thin layer (11) is applied with elevated symbols and around which, once again, there is fixedly arranged an opaque layer (12) with spring elements (2). <IMAGE>

Description

Oppfinnelsen angår en tastknapp for et tastatur som inngårThe invention relates to a key button for a keyboard which is included

i et apparat innen elektrisk informasjonsteknikk, særlig i betjeningsapparatet for en telefoninnretning, hvor tastknappen kan settes inn i en åpning i apparatets kapsel og via en tapp trykkes mot en tast anordnet i det indre av kapselen, og hvor tastknappen, som kan settes inn i åpningen i kapselen med sidelengs klaring, tillike med den passende utformede tapp på minst én side forløper parallelt med kapselåpningen, oppviser et forspent fjærelement som skråner i spiss vinkel mot kapselen og er avstøttet på en anslagsflate i denne, samt ligger an mot kapselens innervegg med oversiden av de av fjærelementene dannede anslagsflater, som har øket diameter i forhold til kapselåpningen og rager utenfor den sidelengs, samt hvor symbolene består av et lysgjennomtrengelig kunststoff og er omgitt av et for lys ugjennomtrengelig kunststoff hos tastaturet. in an apparatus in the field of electrical information technology, in particular in the operating apparatus for a telephone device, where the push button can be inserted into an opening in the device's capsule and via a pin is pressed against a key arranged in the interior of the capsule, and where the push button, which can be inserted into the opening in the capsule with lateral clearance, together with the suitably designed pin on at least one side extending parallel to the capsule opening, having a biased spring element which slopes at an acute angle towards the capsule and is supported on an abutment surface therein, and rests against the inner wall of the capsule with the upper side of the impact surfaces formed by the spring elements, which have an increased diameter in relation to the capsule opening and protrude beyond it laterally, as well as where the symbols consist of a light-transmitting plastic and are surrounded by a light-impermeable plastic at the keyboard.

En slik innretning er beskrevet i DE-OS 33 46 485. For oppset-ning av samtaleforbindelser behøver telefoninnretninger betjeningsapparater og valginnretninger som hittil for det meste har vært forsy.nt med en dreibar velgeskive. Men der finnes også innretninger til formålet, og særlig biltelefoninnret-ninger, som oppviser betjeningsapparater med valgtastaturer hvorved valgoperasjonen blir vesentlig lettet. Tastaturene er i den forbindelse forsynt med for det meste påtrykte siffere eller symboler i samsvar med sin funksjon. Such a device is described in DE-OS 33 46 485. To set up call connections, telephone devices require operating devices and selection devices which have until now mostly been provided with a rotatable dial. But there are also devices for the purpose, and in particular car telephone devices, which have operating devices with selection keypads, whereby the selection operation is significantly facilitated. In this connection, the keyboards are mostly provided with printed numbers or symbols in accordance with their function.

Betjeningsapparatet for en telefoninnretning kan enten væreThe operating device for a telephone device can either be

en separat innretning med tilhørende mikrofon, slik det oftest er tilfellet, eller også være et håndapparat som valg- og visningsenhetene er integrert i. I begge tilfeller behøves tastaturer som manøvreres ved hjelp av tastknapper innsatt i åpninger i kapselen. a separate device with an associated microphone, as is most often the case, or be a hand-held device into which the selection and display units are integrated. In both cases, keyboards are needed that are operated using push buttons inserted in openings in the capsule.

Til grunn for oppfinnelsen ligger den oppgave for slike taster som er beskrevet i det nevnte DE-OS 33 46 485, å gi anvisning på en oppbygning som gjør det mulig å klare seg med mest mulig enkle sprøyteverktøy som i det vesentlige er de samme for forskellige symboler. The basis of the invention is the task for such keys as described in the aforementioned DE-OS 33 46 485, to provide instructions on a structure that makes it possible to manage with the simplest possible injection tools which are essentially the same for different symbols.

Denne oppgave blir ved en anordning av den innledningsvis nevnte art ifølge oppfinnelsen løst på den måte at knappen på frontsiden består av et særskilt, tynt, lysgjennomtrengelig skikt som er fast forbundet med knappens glassklare, lysledende grunnkropp og viser opphøyde symboler, og hvis fordypninger tillike med det for lys ugjennomtrengelige kunststoff danner det tredje skikt som er forbundet med grunnkroppen. This task is solved by a device of the kind mentioned at the outset according to the invention in such a way that the button on the front side consists of a special, thin, light-transmitting layer which is firmly connected to the button's glass-clear, light-conducting base body and shows raised symbols, and whose depressions together with the light-impermeable plastic forms the third layer which is connected to the base body.

Fordelaktige utformninger og videreutviklinger av oppfinnel-sesgjenstanden er angitt i underkravene. Advantageous designs and further developments of the invention are specified in the subclaims.

I det følgende vil oppfinnelsen bli belyst nærmere ved et utførelseseksempel som er vist på tegningen. Fig. 1-4 viser en tastknapp i henholdsvis to på hinannen lodd-rette sideriss, et grunnriss og et lengdesnitt, og In the following, the invention will be explained in more detail by means of an embodiment shown in the drawing. Fig. 1-4 shows a pushbutton in two side views perpendicular to each other, a ground view and a longitudinal section, and

Fig. 5 viser en tastknapp i innbygget tilstand.Fig. 5 shows a button in the built-in state.

Tastknappen 1 består av en mot undersiden åpen, halvskålformet kunststoffdel som har rektangulær form, og på hvis lang- og tverrsider der er anbragt fjærelementer 2, fortrinnsvis ved tilspissing. Disse fjærelementer 2 er festet til hjørnene av tastknappen 1 og forløper i spiss vinkel nedover i forhold til horisontalen, altså innover mot kapselen 6, som de settes inn i. På oversiden er tastknappen 1 utført trappeformet, The push button 1 consists of a semi-bowl-shaped plastic part open to the underside which has a rectangular shape, and on whose long and transverse sides spring elements 2 are placed, preferably by sharpening. These spring elements 2 are attached to the corners of the button 1 and run at an acute angle downwards in relation to the horizontal, i.e. inwards towards the capsule 6, into which they are inserted.

og dens opphøyde midtparti 3 er forsynt med det siffer eller symbol den skal kjennetegnes med. Sifferet resp. symbolet består av et lysgjennomtrengelig skikt 11 av forskjelligfarget, fluorescerende kunststoff. Skiktet er fast forbundet med en kunststoffdel 4 som danner knappens grunnkropp. Denne grunnkropp består av et lysgjennomtrengelig kunststoff som på undersiden går over i en tapp 5. Til dette blir der benyttet et lyssamlende, glassklart kunststoff som tjener som lysleder med lyssamleeffekt. and its raised central part 3 is provided with the number or symbol it is to be identified with. The digit or the symbol consists of a light-permeable layer 11 of different-coloured, fluorescent plastic. The layer is firmly connected to a plastic part 4 which forms the basic body of the button. This base body consists of a light-transmitting plastic which, on the underside, merges into a pin 5. For this, a light-gathering, glass-clear plastic is used which serves as a light guide with a light-gathering effect.

Skiktet 11 er relativt tynt, f.eks. bare 0,4 mm og danner symbolet i opphøyet form. Fordypningene rundt symbolet tillike med den omgivende rand danner det tredje skikt 12 som er ugjennomtrengelig for lys og fast forbundet med de øvrige deler 4, 5 og 11. Oppbygningen av skiktet 12 fremgår tydelig av fig. 4. Dette tredje skikt bærer også fjærelementene 2. Layer 11 is relatively thin, e.g. only 0.4 mm and forms the symbol in a raised form. The recesses around the symbol together with the surrounding edge form the third layer 12 which is impermeable to light and firmly connected to the other parts 4, 5 and 11. The structure of the layer 12 is clearly seen in fig. 4. This third layer also carries the spring elements 2.

Fig. 5 viser den beskrevne tastknapp 1 i innbygget tilstand. Flere tastknapper er hensiktsmessig anordnet i et raster og forsynt med de symboler som tilsvarer deres funksjon. De til-hørende taster 8 er anbragt i samme raster, f.eks. på en lederplate 10, og er i det viste eksempel innloddet via loddeører 9. Fig. 5 shows the described pushbutton 1 in the built-in state. Several buttons are conveniently arranged in a grid and provided with the 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 is soldered in via solder lugs 9.

Tastknappen 1 er innsatt i en åpning i kapselen 6. Der erThe key button 1 is inserted into an opening in the capsule 6. There is

her levnet en sidelengs klaring for å hindre at tastknappen 1 kiler seg fast. Med oversiden av fjærelementene 2 ved sidene ligger tastknappen 1 an mot kapselens innervegg. Fjærelementene a lateral clearance was left here to prevent key button 1 from getting stuck. With the upper side of the spring elements 2 at the sides, the button 1 rests against the inner wall of the capsule. The spring elements

2 er avstøttet mot en anslagsflate dannet av en lysleder 72 is supported against a contact surface formed by a light guide 7

som har en motsvarende boring til å oppta tappen 5 hos tastknappen 1. Lyslederen 7 tjener til tilførsel av lyset til sifrene resp. symbolene i tastknappen 1. which has a corresponding bore to accommodate the pin 5 of the key button 1. The light guide 7 serves to supply the light to the digits or the symbols in key button 1.

For betjening blir tastknappen 1 med sin tapp 5 trykket mot tasten 8 og ført tilbake av fjærelementene 2 - i utførelses-eksempelet fire stykker - på sidene av tastknappen 1. Med disse fjærelementer 2, som består av et passende elastisk kunststoff, er det også sikret at tastknappene ikke klaprer i kapselen og forårsaker en uheldig støy under kjøring. For operation, the button 1 with its pin 5 is pressed against the button 8 and brought back by the spring elements 2 - in the design example four pieces - on the sides of the button 1. With these spring elements 2, which consist of a suitable elastic plastic, it is also ensured that the buttons do not rattle in the capsule and cause an unpleasant noise while driving.

Oppbygningen av tre skikt medfører en betraktelig forenkling av produksjonen, da de vesentlige deler av knappen forblir like for alle symbolarter og der dermed kan spares sprøyte-verktøy. The construction of three layers leads to a considerable simplification of the production, as the essential parts of the button remain the same for all types of symbols and thus saving on spray tools.
