Abstract

A keyboard housing for a key array of a depressible-key keyboard. A parallel guide for multi-wide keys is configured in such a way in the keyboard housing that a swiveling crank arm is limited against longitudinal displacement at both ends and, by two support ribs, is positioned in a vertical direction that its position corresponds precisely to that of the depressed multi-wide key. If the complete set of keys is inserted into the housing and pressed as far as the end stop, the swiveling crank arm latches into snap-in apertures of the multi-wide key, thus becoming functional. The keyboard housing can be used for keyboards produced by automation.

Description

Die Erfindung betrifft ein Tastaturgehäuse gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a keyboard housing according to the preamble of claim 1

Aus EP 0 304 847 B1 ist eine Drucktaste für ein Tastenfeld einer Tastatur mit einem auf einer Grundplatte angeordneten Gehäuse und mit einem langgestreckten, in seiner Längsrichtung parallel zur Grundplatte angeordneten Tastenkörper bekannt, der mit einem in einem Gehäuseschacht axial geführten Stößel verbunden ist und an dem ein Schwenkbügel befestigt ist. Dieser Schwenkbügel weist zwei zur Längsrichtung des Tastenkörpers parallel verlaufende, durch ein Verbindungselement in festem Abstand zueinander gehaltene Bügelachsen auf, von denen die erste in als Einschnappöffnungen ausgebildeten Lagerelementen am Tastenkörper gelagert ist und die zweite Bügelachse aus zwei Achsstutzen besteht, die in zwei seitlichen, jeweils als horizontale Parallelgleitführungen ausgebildeten Aufnahmeelementen gelagert sind.EP 0 304 847 B1 discloses a pushbutton for a keypad a keyboard with a arranged on a base plate Housing and with an elongated, in its longitudinal direction known parallel to the base plate body keys known the one with an axially guided in a housing shaft Tappet is connected and attached to the swivel bracket is. This swivel bar has two to the longitudinal direction of the key body parallel, through a connecting element at a fixed distance to each other held ironing axes, the first of which is designed as snap-in openings Bearing elements is mounted on the key body and the second Bow axle consists of two axle stubs, which in two lateral, each formed as a horizontal Parallelgleitführungen Recording elements are stored.

Der Schwenkbügel ist deswegen vorgesehen, um bei Betätigung der Drucktaste an einem Tastenkörperende einen Teil der Betätigungskraft auf das gegenüberliegende Ende des Tastenkörpers zu übertragen, wodurch ein Kippen des Tastenkörpers verhindert wird, das ein Verkanten des mit dem Tastenkörper verbundenen Stößels in dessen Führung verursachen würde, wodurch letztlich die Funktion der Drucktaste gestört würde. Zum Zwecke einer leichteren Montage der mit dem langgestreckten Tastenkörper versehenen Drucktaste, die auch als Mehrfachtaste bezeichnet wird, ist gemäß EP 0 304 847 B1 auf der Grundplatte wenigstens eine die zweite Bügelachse beim Einführen des Stößels in den Gehäuseschacht aus ihrer Hängestellung in Querrichtung des Tastenkörpers abdrängende und den Aufnahmeelementen zuführende Abgleitschräge vorgesehen. Die Drucktaste läßt sich zwar aufgrund dieser bekannten Maßnahme durch eine einzige eindimensionale Bewegung montieren, die mit einer speziellen Vorrichtung sogar maschinell ausgeführt werden kann. Die endgültige Montage ist jedoch erst dann möglich, wenn der Schwenkbügel mit seiner ersten Bügelachse am Tastenkörper in den dafür vorgesehenen Einschnappöffnungen bereits vorher eingehängt und damit vormontiert ist. Somit ist keine gemeinsame und gleichzeitige Gesamtmontage der Mehrfachtaste mit den anderen für die Tastatur vorgesehenen Tasten möglich.The swivel bracket is therefore provided to actuate the pushbutton at a key body end part of the actuation force on the opposite end of the key body to transfer, causing a tilting of the key body prevents the tilting of the key body associated plunger in its leadership would cause, thereby ultimately the function of the push button would be disturbed. For the purpose of easier assembly with the elongated Button body provided push button, also called multiple button is designated according to EP 0 304 847 B1 on Base plate at least one the second ironing axis during insertion of the plunger in the housing shaft from its suspension position abdrängende in the transverse direction of the key body and the Receiving elements supplying Abgleitschräge provided. The Pushbutton can be due to this known measure mount by a single one-dimensional movement, the even made by machine with a special device can be. However, the final assembly is only then possible when the swivel bar with its first bow axis on Key body in the designated snap openings already mounted before and thus pre-assembled. Consequently is not a common and simultaneous total assembly of the Multiple key with the other provided for the keyboard Keys possible.

Moderne Tastaturen zeichnen sich jedoch dadurch aus, daß aufgrund großer Stückzahlen eine möglichst vollständig automatisierte Fertigung angestrebt wird. So werden heute gewöhnlich alle Tasten einer Tastatur in einem Schuß spritzgegossen und mit einem Handhabungsgerät von der Spritzmaschine direkt in ein Tastaturgehäuse zur Bestückung eingebracht. Davon sind allerdings die sogenannten Mehrfachtasten mit Schwenkbügel, beispielsweise der in EP 0 304 847 B1 beschriebenen Art, ausgeschlossen. Die Bestückung des Tastaturgehäuses mit solchen Mehrfachtasten mit Parallelführungsbügel erfolgt aufgrund von deren komplizierteren Montage in der Regel vollständig von Hand oder nach vorhergehender manueller Anbringung des Schwenkbügels an der Drucktaste mit Hilfe eines speziellen Montagegeräts in separater Nachmontage.Modern keyboards, however, are characterized by the fact that due large quantities of a completely automated Manufacturing is sought. This is how it usually gets today all keys of a keyboard are injection molded in one shot and with a handling device from the spraying machine directly into a keyboard housing for placement introduced. Thereof however, the so-called multiple keys with swivel bracket, for example, the type described in EP 0 304 847 B1, excluded. The equipment of the keyboard housing with such Multiple keys with parallel guide bracket is due to their more complicated assembly usually completely from Hand or after previous manual attachment of the Swivel bracket on the push button with the help of a special Mounting device in separate post-assembly.

Der Erfindung liegt die Aufgabe zugrunde, Maßnahmen anzugeben, die es ermöglichen, auch die Tastenkörper der sogenannten Mehrfachtasten in die Spritzgußform der Tastaturdrucktasten aufzunehmen und alle Tastenkörper eines Tastaturfelds einschließlich der Mehrfachtastenkörper mit dem Handhabungsgerät von der Spritzmaschine direkt in das Tastaturgehäuse zur Bestückung einzubringen.The invention has for its object to provide measures which make it possible, even the key body of the so-called Multiple keys in the injection mold of the keyboard pushbuttons record and all keyboard body of a keypad including the multiple key body with the handling device from the spraying machine directly into the keyboard housing to bring in for loading.

Gemäß der Erfindung wird diese Aufgabe durch die im kennzeichnenden Teil des Patentanspruchs 1 angegebenen Merkmale gelöst. According to the invention, this object is achieved by the characterizing Part of claim 1 specified features solved.

Die Parallelführung für die Mehrfachtaste ist im Tastaturgehäuse nach der Erfindung so gestaltet, daß der Schwenkbügel in äußerst einfacher Weise dort definiert eingelegt werden kann.The parallel guide for the multiple key is in the keyboard housing According to the invention designed so that the swivel bracket be inserted there in a very simple way defined can.

Vorteilhafterweise ist die Parallelführung dabei so ausgebildet, daß der Schwenkbügel in Längsrichtung beidseitig unverschiebbar begrenzt und durch die Auflagerippen in senkrechter Richtung so positioniert ist, daß seine Lage derjenigen der gedrückten Mehrfachtaste entspricht. Wird nun der komplette Drucktastensatz eines Tastaturfelds in das Tastaturgehäuse eingesetzt und bis zum Endanschlag gedrückt, so rastet der vorher definiert ins Tastaturgehäuse eingelegte Schwenkbügel in die dazu vorgesehenen, als Einschnappöffnungen ausgebildeten Lagerelemente der Mehrfachtaste ein und stellt damit die Funktion her.Advantageously, the parallel guide is designed to that the swivel bracket in the longitudinal direction on both sides immovable limited and by the support ribs in vertical Direction is positioned so that its position of the pressed multiple key corresponds. Will now the complete Push-button set of a keypad in the keyboard housing used and pushed to the end stop, so the snaps previously defined in the keyboard housing inserted swivel bracket in the space provided, designed as Einschnappöffnungen Bearing elements of the multiple key and thus represents the Function ago.

Weitere vorteilhafte und zweckmäßige Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.Further advantageous and expedient developments of the invention are given in the subclaims.

Es genügt, wenn auf dem Tastaturgehäuse zwei Auflagerippen vorgesehen sind, die an solchen Stellen oben am Tastaturgehäuse angeordnet sind, daß der Schwenkbügel mit seinen beiden axialen Endbereichen auf ihnen zum Aufliegen kommt. Diese beiden Auflagerippen können so oben auf dem Tastaturgehäuse angeordnet sein, daß die beiden Verbindungselemente des Schwenkbügels an in der Nähe der ersten Bügelachse liegenden Stellen auf ihnen zum Aufliegen kommen.It is sufficient if two Auflagerippen on the keyboard housing are provided in such places on top of the keyboard housing are arranged, that the swivel bracket with its two axial end areas come to rest on them. These Both support ribs can thus be placed on top of the keyboard housing be arranged that the two connecting elements of Swivel bracket at near the first bow axle lying Make them come to rest.

Die zwei seitlichen, jeweils als horizontale Parallelgleitführungen ausgebildeten Aufnahmeelemente für die beiden Achsstutzen des Schwenkbügels weisen in vorteilhafter Weise jeweils eine untere horizontale Gleitfläche und eine obere horizontale Gleitfläche auf, die voneinander einen der Schwenkbügelstärke entsprechenden Abstand haben. Die beiden Aufnahmeelemente enthalten zur Einführung des jeweiligen Achsstutzens des Schwenkbügels zwischen die beiden Gleitflächen und zur damit zugleich verbundenen Schrägeinführung des betreffenden Verbindungselements des Schwenkbügels jeweils eine L-förmige Öffnung. Die äußeren seitlichen Kanten der beiden L-förmigen Öffnungen sind dabei so angeordnet, daß ihr gegenseitiger Abstand der Schwenkbügelausdehnung in Längsrichtung, d.h. dem Außenabstand der Verbindungselemente des Schwenkbügels, entspricht. Durch diese Maßnahmen ist einerseits die Gleitverschieblichkeit der beiden Achsstutzen des Schwenkbügels beim Einschieben in die beiden Aufnahmeelemente mit der Parallelführung und andererseits die Begrenzung des Schwenkbügels gegen Längsverschiebung sichergestellt.The two lateral, each as a horizontal Parallelgleitführungen trained receiving elements for the two axle stubs of the pivot bracket point in each case in an advantageous manner a lower horizontal sliding surface and an upper horizontal one Sliding surface on each other one of the swivel bracket thickness have appropriate distance. The two receiving elements included for the introduction of the respective axle stub of the swivel bracket between the two sliding surfaces and for the associated at the same time oblique introduction of the relevant Connecting element of the swivel bracket one each L-shaped opening. The outer side edges of the two L-shaped openings are arranged so that their mutual Distance of the swivel arm extension in the longitudinal direction, i.e. the outer distance of the connecting elements of the swivel bracket, equivalent. By these measures is on the one hand the Gleitverschieblichkeit the two axle tube of the swivel bracket when inserted into the two receiving elements with the Parallel guide and on the other hand, the limitation of the swivel bracket ensured against longitudinal displacement.

Die vorstehend angegebenen Merkmale und Weiterbildungen, welche die Anbringung des Mehrfachtastenkörpers mit seinem Schwenkbügel am Tastaturgehäuse betreffen, sind vorzugsweise im Bereich seiner beiden Enden und zwar spiegelsymmetrisch bezüglich seiner quer zur Längsrichtung liegenden Mittelebene vorgesehen. Durch diese Maßnahme und zusätzlich in zweckmäßiger Weise noch durch die Maßnahme, wonach am Tastenkörper zu beiden Seiten des in seiner Mitte angeordneten Stößels dazu parallele, in zugeordneten Gehäuseschächten axial geführte Hilfsstößel angeordnet sind, wird ein Verkippen des Tastenkörpers sicher verhindert.The above features and developments, which the attachment of the multi-key body with his Pivoting stirrups on the keyboard housing are preferred in the region of its two ends and that mirror-symmetrical with respect to its transverse to the longitudinal center plane intended. By this measure and in addition in appropriate Way even by the measure, which according to the key body on both sides of the ram in its center parallel, in associated housing shafts axially guided Sub-tappets are arranged, a tilting of the key body safely prevented.
