Description

Die Erfindung betrifft einen Druckknopf für Tastschalter gemäß Oberbegriff des Anspruchs 1.The invention relates to a push button for push buttons according to the preamble of claim 1.

Aus der DE-AS 1 263 894 ist ein Druckknopftaster bekannt, dessen Druckknopf mittels zweier angeformter, federnder Rasthaken hinter ebensolchen, an einer Montageplatte entgegengesetzt gerichteten Haken verrastbar ist. Im eingerasteten Zustand ist zugleich die Ruhestellung der Taste definiert, in die sie durch die Rückstellfeder gebracht wird.From DE-AS 1 263 894 a push button switch is known, the push button of which can be locked by means of two molded, resilient locking hooks behind the same hooks, which are oppositely directed on a mounting plate. In the locked state, the rest position of the button is defined, into which it is brought by the return spring.

Der Erfindung liegt die Aufgabe zugrunde, einen Druckknopf entsprechend dem Oberbegriff des Anspruchs 1 für handelsübliche Tastschalter zu schaffen, der es ermöglicht, die der Druckkraft entgegenwirkende Rückstellkraft des Tastschalters zu variieren. Die Aufgabe wird durch die im Kennzeichen des Anspruchs 1 angegebenen Merkmale gelöst. Vorteilhafte Weiterbildungen sind den Unteransprüchen zu entnehmen. Die erfindungsgemäße Konstruktion erlaubt es, bedarfsweise durch Lösen des Riegelstückes einen weiteren Kraftspeicher, z.B. eine Druckfeder, in den Druckknopf einzusetzen, dessen Kraft der des im Tastschalter bereits vorhandenen Kraftspeichers hinzugefügt wird. Das Lösen und Wiedereinsetzen des Riegelstückes kann auf einfache Weise, z.B. mittels einer Münze erfolgen, ohne daß der Druckknopf selbst oder gar der Tastschalter demontiert werden muß. Die Oberseite des Druckknopfes kann in eleganter Weise durch eine Abdeckung verschlossen werden, die, sofern sie durchsichtig ausgeführt ist, außerdem Gelegenheit zum Einlegen eines Beschriftungs-oder Symbolzettels gibt. Die Erfindung ist besonders dann von Vorteil, wenn es darum geht, die Rückstellkraft von Tastschaltern den Bedürfnissen von mehr oder weniger stark behinderten Personen anzupassen. Die Notwendigkeit besteht insbesondere in Kliniken, in denen während relativ kurzer Zeiträume die Rückstellkräfte bei Ruf- und Wähltastenanordnungen des öfteren geändert werden sollen.The invention has for its object to provide a push button according to the preamble of claim 1 for commercially available key switches, which makes it possible to vary the restoring force of the key switch counteracting the pressure force. The object is achieved by the features specified in the characterizing part of claim 1. Advantageous further developments can be found in the subclaims. The construction according to the invention makes it possible, if necessary, to insert a further energy store, for example a compression spring, into the push button by loosening the locking piece, the force of which is added to that of the energy store already present in the pushbutton switch. The locking piece can be released and reinserted in a simple manner, for example by means of a coin, without the push button itself or even the push-button switch having to be removed. The top of the push button can be elegantly covered by a cover be closed, which, if it is made transparent, also gives the opportunity to insert a label or symbol. The invention is particularly advantageous when it comes to adapting the restoring force of push buttons to the needs of more or less severely disabled people. The need exists in particular in clinics in which the restoring forces in call and dial button arrangements are to be changed frequently over a relatively short period of time.

Die Erfindung wird nun an Ausführungsbeispielen näher beschrieben, die in den zugehörigen Zeichnungen dargestellt sind. Es zeigen:

  • Fig.1 einen Längsschnitt durch einen erfindungsgemäßen Druckknopf in eingebautem Zustand;
  • Fig.2 einen Querschnitt entsprechend Linie II-II in Fig.1, und
  • Fig.3 eine andere Ausführung des Druckknopfes, im Längsschnitt.
The invention will now be described in more detail using exemplary embodiments which are illustrated in the accompanying drawings. Show it:
  • 1 shows a longitudinal section through a push button according to the invention in the installed state;
  • 2 shows a cross section along line II-II in Fig.1, and
  • 3 shows another embodiment of the push button, in longitudinal section.

Der in Fig.1 und 2 dargestellte Druckknopf 1 hat im wesentlichen quaderförmige Gestalt. Auf der Außenseite sind nahe der Unterkante zwei oder drei Rastnasen 16 an den zweckmäßig aus Kunststoff gefertigten Druckknopf angeformt. Beim Aufsetzen auf den Tastschalter 13 rasten diese Rastnasen 16 hinter den entgegengesetzt gerichteten Rastnasen 15 an federnden Rasthaken 14 ein, welche aufrecht stehend an der Montageplatte 18 angesetzt sind, in welcher auch der Tastschalter 13 befestigt ist. Die ganze Anordnung wird zweckmäßig durch eine Abdeckplatte 19 mit einer entsprechenden öffnung 20 abgedeckt, durch die der Druckknopf 1 herausragt.The push button 1 shown in FIGS. 1 and 2 has a substantially cuboid shape. On the outside, near the lower edge, two or three locking lugs 16 are molded onto the push button, which is expediently made of plastic. When placed on the pushbutton switch 13, these locking lugs 16 snap behind the opposite locking lugs 15 on resilient locking hooks 14, which are placed upright on the mounting plate 18, in which the pushbutton switch 13 is also fastened. The entire arrangement is expediently covered by a cover plate 19 with a corresponding opening 20 through which the push button 1 protrudes.

Unten ist der Druckknopf 1 offen und im Inneren im wesentlichen hohl, besitzt jedoch in der oberen Wand 23 einen runden Durchbruch 24, an den sich ein rohrförmiger Ansatz 21 anschließt. In diesen Durchbruch 24 bzw. Ansatz 21 ist von oben her das zylindrische Riegelstück 2 einfügbar, das mitteils Einrenkung mit dem Druckknopf 1 verbunden werden kann. Für die Einrenknasen 4 des Riegelstückes 2 sind entsprechende Erweiterungen 22 an dem Durchbruch 24 des Druckknopfes vorgesehen, die das Einfügen ermöglichen. Die Einrenknasen 4 können hinterschnitten sein (Fig.1), um Zentrierung und Reibung zu verbessern.At the bottom, the push button 1 is open and essentially hollow on the inside, but has a round opening 24 in the upper wall 23 to which a tubular extension 21 is attached closes. In this opening 24 or approach 21, the cylindrical locking piece 2 can be inserted from above, which can be connected to the pushbutton 1 by means of restraint. For the Einrenknasen 4 of the locking piece 2 corresponding extensions 22 are provided on the opening 24 of the push button, which allow insertion. The Einrenknasen 4 can be undercut (Fig.1) to improve centering and friction.

Außerdem können am Umfang des Riegelstückes 2 Rastnocken 5 angebracht sein, die beim Drehen des Riegelstückes 2 in Pfeilrichtung (Fig.2) hinter freigeschnittenen federnden Lappen 6 des Druckknopfes einschnappen. Dadurch wird ein selbsttätiges Lösen sicher verhindert. Für das gewollte Drehen (Verriegeln oder Lösen) ist auf der Oberseite des Riegelstückes 2 ein segmentförmiger Schlitz 7 zum Ansetzen einer Münze als Werkzeug vorgesehen.In addition, locking cams 5 can be attached to the circumference of the locking piece 2, which snap in when the locking piece 2 is turned in the direction of the arrow (FIG. 2) behind the resilient tabs 6 of the push button that are cut free. This reliably prevents automatic loosening. For the intended turning (locking or releasing) a segment-shaped slot 7 is provided on the top of the locking piece 2 for attaching a coin as a tool.

Bei dem Riegelstück 2 handelt es sich um einen oben geschlossenen Hohlzylinder, in dem ein rohrförmiger, an die Stirnwand angeformter Ansatz 8 enthalten ist. Dieser Ansatz hat zweierlei Funktionen: im Inneren nimmt er den Stößel 9 des Tastschalters 13 auf, während über seine Außenfläche eine Schraubendruckfeder 3 geschoben werden kann. Diese den benötigten Werten entsprechend dimensionierte Feder 3 unterstützt in ihrer Wirkung die des Kraftspeichers 17, der in dem handelsüblichen Tastschalter 13 bereits eingebaut ist.The locking piece 2 is a hollow cylinder closed at the top, in which a tubular extension 8 formed on the end wall is contained. This approach has two functions: on the inside it receives the plunger 9 of the pushbutton switch 13, while a helical compression spring 3 can be pushed over its outer surface. The effect of this spring 3, which is dimensioned according to the required values, supports that of the energy accumulator 17, which is already installed in the commercially available pushbutton switch 13.

Auf seiner Oberseite ist dem Druckknopf 1 die Abdeckung 10 aufgesetzt, die ihm einen zweckmäßigen Abschluß verleiht. Wird sie aus undurchsichtigem Material hergestellt, so ist für Unbefugte nicht ohne weiteres offensichtlich, welche Möglichkeiten dem Druckknopf innewohnen. Wird sie aus durchsichtigem Formstoff gefertigt, so kann ein Beschriftungsblatt 12 eingelegt werden, auf dem Symbole oder Schriftzeichen angebracht sind. Der Druckknopf ist auf der Oberseite etwas vertieft, in den umlaufenden Rand 25 paßt formschlüssig die entsprechend abgestufte Abdeckung 10, so daß sie außen bündig steht. Um die beispielsweise mit einer flachen Wulst einrastende Abdeckung 10 leicht lösen zu können, ist an einer Stelle am oberen Rand des Druckknopfes 1 eine kleine Ausnehmung 11 vorgesehen, in der z.B. ein Fingernagel angesetzt werden kann.On its top, the push button 1, the cover 10 is placed, which gives it an appropriate conclusion. If it is made of opaque material, it is not immediately obvious to unauthorized persons which options are inherent in the push button. If it is made of transparent molding material, a label 12 can be inserted, on the symbols or writing characters are attached. The push button is slightly recessed on the top, the correspondingly graduated cover 10 fits into the peripheral edge 25 so that it is flush on the outside. In order to be able to easily release the cover 10, which for example snaps into place with a flat bead, a small recess 11 is provided at one point on the upper edge of the push button 1, in which a fingernail can be attached, for example.

In Fig.3 ist eine andere Ausführung des Druckknopfes gezeigt, bei der zwei zusätzliche Schraubendruckfedern zur Anwendung kommen. Im äußeren Aufbau ist er dem zuvor anhand der Fig.1 und 2 beschriebenen Druckknopf 1 ähnlich, weshalb zum Teil die gleichen Bezugszeichen verwendet werden. Die Rastnasen 36 sind hier allerdings Bestandteil federnder Rasthaken 37, die am unteren Rand des Druckknopfes 31 in Verlängerung seiner Seitenwände soweit vorspringen, daß sie hinter der Montageplatte 38 einrasten. Letztere ist mit entsprechenden Durchbrüchen 39 für den Durchtritt der Rasthaken 37 versehen. Dafür sind die angeformten Rasthaken 14 (Fig.1) entfallen. Innen fehlt dem Druckknopf 31 das zentrale Riegelstück. Statt dessen sind an der Stirnwand des Druckknopfes 31 symmetrisch zur Mitte zwei rohrförmige Ansätze 35 mit durchgehender Bohrung angeformt, die zur Aufnahme je einer Schraubendruckfeder 33 dienen. Auf der Oberseite des Druckknopfes 31 sind die Bohrungen für die Federn 33 etwas erweitert und durch passende Riegelstücke 32 verschlossen, die eingerastet oder eingerenkt sind. Zu ihrer Betätigung sind sie mit einem Schlitz 34 versehen.3 shows another embodiment of the push button in which two additional helical compression springs are used. In terms of its outer structure, it is similar to push button 1 previously described with reference to FIGS. 1 and 2, which is why the same reference numerals are used in part. The locking lugs 36 are here, however, part of resilient locking hooks 37, which protrude at the bottom of the push button 31 in the extension of its side walls so far that they snap behind the mounting plate 38. The latter is provided with corresponding openings 39 for the passage of the locking hook 37. For this, the molded locking hooks 14 (Fig. 1) have been omitted. Inside the push button 31 is missing the central locking piece. Instead, two tubular projections 35 are formed on the end wall of the push button 31 symmetrically to the center with a through-bore, which serve to receive a helical compression spring 33 each. On the top of the push button 31, the bores for the springs 33 are somewhat expanded and closed by suitable locking pieces 32, which are engaged or engaged. To operate them, they are provided with a slot 34.

Anstelle des rechteckigen Grundrisses können die Druckknöpfe 1 und 31 auch einen runden Grundriß haben. Die Rasthaken 14 bzw. 37 sind dann entweder diagonal oder, wenn es mehr als zwei sind, den Gegebenheiten entsprechend am Umfang verteilt angeordnet.Instead of the rectangular floor plan, the push buttons 1 and 31 can also have a round floor plan. The latching hooks 14 and 37 are then either arranged diagonally or, if there are more than two, distributed around the circumference according to the circumstances.

Die Druckfedern 3 bzw. 33 werden am Einsatzort eingesetzt oder den Erfordernissen entsprechend ausgetauscht.Beispielsweise werden sie dem Therapeuten einer Klinik zur Verfügung gestellt, der sie bei der Betreuung von Behinderten mit gestörter Bewegungskoordination in von diesen bedienbaren Geräten, wie Fernsprechapparate, Steuervorrichtungen für Fenster, Rolläden usw., einsetzt. Diese Behinderten können normale Bedientasten (Bedienkraft ca. 50 bis 100 cN) nicht fehlerfrei bedienen, da ihnen die Positionierung des Fingers auf dem Druckknopf bereits Mühe bereitet und dabei Wischkontaktbetätigungen ausgelöst werden. Durch Einsetzen entsprechender Zusatzfedern 3 bzw. 33 kann die Bedienkraft soweit gesteigert werden (bis maximal etwa 20 N), daß Fehlbetätigungen weitgehend ausgeschlossen werden können.The compression springs 3 and 33 are used in the field or as necessary and ausgetauscht.Beispielsweise they are made available to the therapist a clinic available, they in the care of disabled people with impaired motor coordination in-use of these devices, such as Ferns computing apparatus p, control devices for Windows, shutters, etc. These handicapped people cannot operate normal operating buttons (operating force approx. 50 to 100 cN) without error, since positioning the finger on the push button is already difficult and triggering swipe contact operations. By using appropriate additional springs 3 and 33, the operating force can be increased to such an extent (up to a maximum of about 20 N) that incorrect operations can largely be ruled out.
