Abstract

The invention relates to an electromotive drive that comprises at least one driving motor and that is controlled by a operating element via a control element, said operating element having a plurality of actuation elements that can be optionally blocked. The aim of the invention is to improve the design of such a drive, allowing to block for the user or patient the functions triggered by the actuation elements of the operating element, and to allow for the blockable functions to be easily changed. The inventive device should further have a self-check or self-diagnosis mode in order to avoid malfunctions. To this end, the operating element (10) is provided with a selection device that allows the user to select only predetermined functions. Said selection device is configured in such a manner that the operating element, preferably a manual switch, triggering several functions, can be freely programmed. The inventive drive is sufficiently functional in order to prevent malfunctions by way of a self-check, self-monitoring or self-diagnosing mode. The electromotive drive is especially suitable for the adjustment devices of furniture in the field of hospital or nursing care.

Description

Die Erfindung betrifft einen elektromotorischen Antrieb für Verstelleinrichtungen für Möbel mit mindestens einem Antriebsmotor, der über eine Steuereinheit mittels eines Bedienerteiles ansteuerbar ist, der mehrere Betätigungselemente aufweist, die wahlweise sperrbar sind.The invention relates to an electric motor drive for adjusting devices for furniture with at least one drive motor, which means a control unit of an operator part can be controlled, which has a plurality of actuating elements which are optionally lockable.

Der in Frage kommende elektromotorische Antrieb wird bevorzugt für elektromotorische Möbelantriebe verwendet, die bevorzugt im Krankenhausbereich oder im Pflegebereich eingesetzt werden. In diesen medizinischen Bereichen werden besondere Sicherheiten verlangt, damit die als Bediener auftretenden Patienten oder die pflegebedürftigen Personen nicht gefährdet werden.The electric motor drive in question is preferred for electric motor drives Furniture drives used, which are preferred in the hospital area or in Care area. In these medical fields, they become special Collateral is required so that the patients appearing as the operator or the people in need of care are not endangered.

Dem Bedienerteil ist die Steuereinheit zugeordnet. Das Bedienerteil ist mit mehreren Betätigungselementen, beispielsweise acht Drucktastern ausgestattet, um unterschiedliche Funktionen auszulösen. Die vom Bedienerteil in die Steuereinheit einzuspeisenden Signale können über Steuerkabel oder auch drahtlos übertragen werden. Es muß außerdem sichergestellt sein, daß Fehlfunktionen vermieden werden, die beispielsweise durch eine Beschädigung des Steuerkabels oder durch Fremdsignale ausgelöst werden können.The control unit is assigned to the operator part. The operator part is with several Actuators, for example eight push buttons equipped to different Trigger functions. Those to be fed into the control unit by the operator part Signals can be transmitted via control cables or wirelessly. It must also be ensured that malfunctions are avoided for example due to damage to the control cable or external signals can be triggered.

Es ist im Krankenhausbereich und auch im Pflegebereich notwendig, daß von den Patienten bzw. pflegebedürftigen Personen verschiedene Funktionen nicht ausgelöst werden dürfen, damit sie nicht gefährdet werden. Da jedoch das Pflegepersonal diese Funktionen benötigt, ist es bekannt, daß das Pflegepersonal einen Schlüsseltaster o.dgl. erhält, der in den Handschalter eingesteckt wird, woraufhin dann alle Funktionen ausgelöst werden können. Es ist außerdem bekannt, daß bei der Betätigung der Bedienelemente des Bedienerteils Signale über einen Baustein in die Steuerung übertragbar sind und daß das Bedienerteil außerdem mit einem Sicherheitsschalter ausgestattet ist, so daß das gesendete Signal zunächst kodiert und vor Einspeisung in den Baustein wieder dekodiert wird. Durch diese Lösung wird ein geringer steuerungstechnischer Aufwand notwendig, obwohl die Funktionen voll erhalten bleiben und die geforderten Sicherheitsanforderungen voll erfüllt werden. Im Krankenhaus und auch im Pflegebereich wechseln die Patienten sehr häufig. Da je nach dem Pflegefall bzw. nach der Erkrankung entsprechende Funktionen gesperrt werden müssen, ist die Änderung von gesperrten Funktionen bei den bislang bekannten Bedienerteilen recht aufwendig. Dies kann sogar dazu führen, daß das Pflegepersonal nicht in der Lage ist, solche Änderungen durchzuführen.It is necessary in the hospital area and also in the nursing area that of the Various functions were not triggered by patients or persons in need of care be allowed so that they are not endangered. However, since the nursing staff requires these functions, it is known that the nursing staff have a key switch or the like. receives, which is inserted into the hand switch, whereupon all Functions can be triggered. It is also known that when actuated the controls of the operator part signals via a block in the Control are transferable and that the operator part also with a safety switch is equipped so that the transmitted signal is initially coded and before Infeed into the block is decoded again. With this solution, a little control effort required, although the functions are full remain intact and the required security requirements are fully met. In the hospital and also in the nursing area, the patients change very often. There Depending on the case of care or the illness, corresponding functions are blocked must be the change of locked functions in the previous known operator parts quite expensive. This can even lead to the fact that Nursing staff is unable to make such changes.

Der Erfindung liegt die Aufgabe zugrunde, einen elektromotorischen Antrieb der eingangs näher beschrieben Art so zu gestalten, daß in einfachster Weise durch Betätigungselemente des Bedienerteils auslösbare Funktionen für den Bediener bzw. für den Patienten gesperrt werden können, und daß in einfachster Weise die zu sperrenden Funktionen geändert werden können. Gleichzeitig soll eine Selbstüberprüfung bzw. eine Selbstdiagnose zwecks Vermeidung von Fehlfunktionen realisierbar sein.The invention has for its object an electric motor drive type described in more detail at the outset so that in the simplest way Operating elements of the operator part triggerable functions for the operator or can be blocked for the patient, and that in the simplest way functions to be blocked can be changed. At the same time, a self-check is supposed to or self-diagnosis to avoid malfunctions be feasible.

Die gestellte Aufgabe wird gelöst, indem das Bedienerteil derart mit einer Auswahleinrichtung ausgestattet ist, daß für den Bediener ausschließlich vorbestimmte Funktionen verfügbar sind. Die Auswahleinrichtung ist so ausgelegt, daß das Bedienerteil, vorzugsweise ein Handschalter, der mehrere Funktionen auslösen kann, frei programmierbar ist. Dabei erfolgt die Auslegung so, daß eine ausreichend freie Funktionskapazität zur Vermeidung von Fehlfunktionen mittels einer automatischen Selbstprüfung, einer Selbstüberwachung oder einer Selbstdiagnose zur Verfügung steht. Eine solche Einrichtung ist äußerst einfach aufgebaut und so ausgelegt, daß die Auswahl der dem Patienten zur Verfügung stehenden Funktionen in einfachster Weise eingestellt werden kann. Dadurch besteht die Möglichkeit, daß während der Behandlung eines Patienten oder beim Wechsel eines Patienten die ihm zur Verfügung stehenden Funktionen geändert werden können.The object is achieved in that the operator part with a selection device is equipped that only predetermined for the operator Functions are available. The selection device is designed so that the operator part, preferably a hand switch that can trigger several functions, is freely programmable. The design is such that a sufficiently free Functional capacity to avoid malfunctions using an automatic Self-examination, self-monitoring or self-diagnosis are available stands. Such a device is extremely simple and designed to that the selection of the functions available to the patient in can be set in the simplest way. This creates the possibility that during the treatment of a patient or when changing a patient functions available to him can be changed.

Soll ein Patient alle Funktionen auslösen können oder vor einer neuen Auswahl der auslösbaren Funktionen ist es zweckmäßig, wenn mittels einer Aktiviereinrichtung die gesperrten Funktionen entsperrbar sind, so daß dann alle Funktionen zur Verfügung stehen. Das Aktivierelement kann alle Funktionen sperren und entsperren. Damit kann die Forderung gemäß einer einschlägigen Norm nach einer Erstfehlersicherheit des Bedienteiles erfüllt werden, wenn das Aktivierelement in der jeweiligen Anwendung als geeignetes, normgerechtes Bauteil ausgelegt ist. Die Aktiviereinrichtung kann ein loser Dauermagnet, ein in das Bedienelement einsteckbarer Schlüsselschalter o.dgl. sein. Die Aktiviereinrichtung bzw. das Aktivierelement ist dann nur berechtigten Personen, beispielsweise dem Pflegepersonal zugänglich. Durch die Auswahleinrichtung ist es möglich, daß durch die freie Programmierbarkeit nach Belieben Funktionen der Bedieneinrichtung ein- oder ausgeschaltet werden können. Das Aktivierelement kann sich auf der Rückseite des Bedienteiles befinden. Es kann auch z. B. ein Drehschalter oder ähnliches sein, der nur mit einem geeigneten Werkzeug, beispielsweise einem Schlüssel, betätigbar ist.Should a patient be able to trigger all functions or before a new selection of the triggerable functions, it is useful if by means of an activation device the locked functions can be unlocked so that all functions are available stand. The activation element can lock and unlock all functions. This means that the requirement according to a relevant standard for first-time safety can be met of the control panel are met when the activation element in the respective Application is designed as a suitable, standardized component. The activation device can be a loose permanent magnet, a pluggable into the control element Key switch or the like his. The activation device or the activation element is then only accessible to authorized persons, such as nursing staff. Through the selection device it is possible that through the free programmability Functions of the control device can be switched on or off as required can. The activation element can be located on the back of the control panel. It can also e.g. B. be a rotary switch or the like, the only one suitable tool, for example a key, can be actuated.

Eine hohe Sicherheit wird erreicht, wenn die Funktionskapazität der Auswahleinrichtung so ausgelegt ist, daß gleichzeitig Aufgaben zur Funktionsprüfung und Selbstdiagnose zur Fehlervermeidung durchführbar sind.A high level of security is achieved if the functional capacity of the selection device is designed so that at the same time tasks for functional testing and Self-diagnosis can be carried out to avoid errors.

Eine kostengünstige, funktionssichere Ausführung wird erreicht, wenn die Auswahleinrichtung einen Mikroprozessor als zentralen Baustein beinhaltet. In weiterer Ausgestaltung ist es noch zweckmäßig, wenn das Bedienteil mit einem Freigabebetätigungselement derart ausgestattet ist, daß eine Funktion nur bei betätigtem Freigabebetätigungselement auslösbar ist. Das Freigabebetätigungselement könnte in bevorzugter Ausführung eine Freigabetaste sein. Es wird dann eine sogenannte Zweihandbedienung notwendig, da zur Auslösung einer bestimmten Funktion immer gleichzeitig das Freigabebetätigungselement betätigt werden muß.An inexpensive, functionally reliable design is achieved if the selection device contains a microprocessor as the central component. In another Embodiment, it is still useful if the control panel with a release actuator is equipped so that a function only when activated Release actuator can be triggered. The release actuator could in a preferred embodiment be a release button. Then it becomes a so-called Two-hand operation is necessary because it always triggers a certain function at the same time the release actuator must be operated.

Anhand der beiliegenden Zeichnung wird die Erfindung noch näher erläutert. Es zeigt:

Wie durch die Pfeile angedeutet, werden die beim Betätigen eines der Bedienelemente 13 gesendeten Signale in einen Baustein 16 der Steuereinheit 11 eingespeist. Nach entsprechender Verarbeitung werden die Signale zur Auslösung der gewünschten Funktion den Elektromotoren des elektromotorischen Antriebs übermittelt. Dies ist durch die Pfeile 17 symbolisch dargestellt.In the block diagram according to FIG. 1, the operator part is identified by reference number 10. The associated control unit is identified by reference number 11. The operator part 10 contains a keyboard 12 with several operating elements or actuating elements 13 in the form of push buttons. In a preferred embodiment, the keyboard 12 is equipped with eight operating elements 13.
The operator part is connected to the control unit 11 by a control cable 15, which in the exemplary embodiment shown contains eight wires. As indicated by the arrows, the signals transmitted when one of the operating elements 13 is actuated are fed into a module 16 of the control unit 11. After appropriate processing, the signals for triggering the desired function are transmitted to the electric motors of the electric motor drive. This is symbolically represented by the arrows 17.

In nicht näher dargestellter Weise ist das Bedienerteil 10 zur freien Programmierung mit einer Auswahleinrichtung ausgestattet, um ausgewählte Bedienelemente 13 für den Patienten zu sperren. Sofern eine andere Auswahl getroffen wird oder alle Bedienelemente 13 zur Verfügung stehen sollen, können die zunächst gesperrten Bedienelemente 13 mittels eines Aktivierelementes entsperrt werden, so daß sie wieder benutzbar sind. Es kann dann eine neue Auswahl getroffen werden. Die Auswahleinrichtung kann z.B. einen Mikroprozessor als zentralen Steuerbaustein beinhalten, dessen Leistungsfähigkeit zusätzlich dazu verwendet wird, gleichzeitige Überwachungs- und Prüfaufgaben zur Vermeidung von Fehlfunktionen durchzuführen.In a manner not shown, the operator part 10 is for free programming equipped with a selection device to selected control elements 13 to block for the patient. Unless another selection is made or all controls 13 should be available, the initially locked Controls 13 are unlocked by means of an activation element, so that they are usable again. A new selection can then be made. The Selection means can e.g. a microprocessor as the central control module contain, whose performance is used in addition to simultaneous Carry out monitoring and testing tasks to avoid malfunctions.
