Abstract

The control device is provided with signal transmitters (4) and with a safety arrangement (5, 35), in order to prevent signal emission, in that a locking device (5) is pivoted, as a result of which the pressing-in movement of the push-button head (12) of the push-button switch (4) blocks or, with the aid of a valve (35), interrupts the transmission line (31). The locking or interruption takes place on the control device itself, the position of the lock being indicated at the same time. <IMAGE>

Description

Die Erfindung betrifft eine Steuervorrichtung mit mindestens zwei nebeneinander liegenden Signalgebern, insbesondere zur Steuerung von Spitalmobiliar, die jeweils einen Antriebsmechanismus mit Tastenknöpfen aufweisen.The invention relates to a control device with at least two signal generators located next to one another, in particular for controlling hospital furniture, each of which has a drive mechanism with button buttons.

Eine derartige Steuervorrichtung ist aus der US-A-3,080,720 bekannt. Diese bekannte Steuervorrichtung dient als Fernsteuerung eines Schaltkastens. Der Patient kann hierdurch selbst die verschiedenen Bewegungen bei seinem Spitalbett vornehmen. Sollte hierbei aber eine unbefugte (vom Arzt oder von den Krankenschwestern nicht gewünschte) Spitalbett-Bewegung unterbleiben, müsste diese Sperrung der Spitalbett-Bewegung am Schaltkasten selbst vorgenommen werden, denn an der Steuervorrichtung selbst kann keine derartige Sperrung vorgenommen werden.Such a control device is known from US-A-3,080,720. This known control device serves as remote control of a control box. This enables the patient to carry out the various movements in his hospital bed himself. However, if an unauthorized movement of the hospital bed (not desired by the doctor or the nurses) should not take place, this blocking of the hospital bed movement would have to be carried out on the switch box itself, because no such blocking can be carried out on the control device itself.

Durch die CA-A-1 263 541 ist ein in zwei Stellungen kippbarer Schalter bekannt, bei dem die Kippbewegung durch einen drehbaren Exzenternocken gesperrt werden kann, so dass der Schalter in seiner Aus-Stellung gehalten wird. Würde man zwei solche Schalter nebeneinander anordnen, hätte man zwei Exzenternocken, die hintereinander liegen und durch eine einzige drehbare Achse betätigt werden könnten. Diese Achse liegt quer zur Bewegungsrichtung des Schalters bzw. würde quer liegen zur Bewegungsrichtung der beiden Schalter und muss daher unterhalb des oder der Schalter liegen, wodurch die Dicke der Steuervorrichtung stark vergrössert werden würde, besonders dann, wenn die Signalgeber pneumatische Tastschalter sind, bei denen dann noch Kolben und federelastische Rückstellorgane vorhanden sein müssen (wie beim Gegenstand der US-A-3 080 720).CA-A-1 263 541 discloses a switch which can be tilted into two positions, in which the tilting movement can be blocked by a rotatable eccentric cam, so that the switch is held in its off position. If you arranged two such switches next to each other, you would have two eccentric cams, which are located one behind the other and could be actuated by a single rotating axis. This axis lies transversely to the direction of movement of the switch or would lie transversely to the direction of movement of the two switches and must therefore lie below the switch or switches, as a result of which the thickness of the control device would be greatly increased, especially if the signal transmitters are pneumatic pushbuttons, in which then there must still be pistons and resilient return members (as in the subject of US-A-3 080 720).

Insbesondere bei der Steuerung von Bettenmotoren für Spitalbetten, bei der jeweils zwei Signalgeber für die Steuerung eines Motors benötigt werden, waren besondere Massnahmen erforderlich, um eine unbefugte Verstellung von Teilen des Bettes zu verhindern. Wegen den hohen Sicherheitsanforderungen mussten besondere Verriegelungsschaltungen in eigens dafür vorgesehenen Schaltkästen vorgesehen werden.Especially when controlling bed motors for hospital beds, each with two signal transmitters to control an engine, special measures were required to prevent unauthorized adjustment of parts of the bed. Due to the high safety requirements, special interlocking circuits had to be provided in switch boxes provided for this purpose.

Als nachteilig erweist sich dabei die Unübersichtlichkeit über die bereits vorgenommene Verriegelung und die gesonderte Einstellung der Verriegelung ausserhalb der Steuervorrichtung als auch die hohen Kosten für solche Anlagen.A disadvantage here is the lack of clarity about the locking already carried out and the separate setting of the locking outside the control device, as well as the high costs for such systems.

Hier will die Erfindung Abhilfe schaffen. Die erfindungsgemässe Ausbildung der Steuervorrichtung ergibt sich aus dem kennzeichnenden Teil des Patentanspruchs 1. Hierdurch kann die Verriegelung an der Steuervorrichtung des Bettes selbst vorgenommen werden.The invention seeks to remedy this. The design of the control device according to the invention results from the characterizing part of patent claim 1. This allows the locking of the control device of the bed itself.

Als Spitalmobiliar kommen Röntgeneinheiten, Therapietische, Pflegebetten oder Spitalbetten infrage.X-ray units, therapy tables, nursing beds or hospital beds come into consideration as hospital furniture.

Weitere Ausführungsformen der Erfindung ergeben sich aus den abhängigen Ansprüchen.Further embodiments of the invention result from the dependent claims.

Im folgenden wird die Erfindung anhand eines Ausführungsbeispiels in der beiliegenden Zeichnung erläutert.The invention is explained below using an exemplary embodiment in the accompanying drawing.

Es zeigen:

  • Figur 1 eine teilweise aufgebrochen dargestellte Draufsicht auf die Steuervorrichtung, und
  • Figur 2 eine teilweise aufgebrochen dargestellte Seitenansicht der Steuervorrichtung gemäss Figur 1.
Show it:
  • Figure 1 is a partially broken plan view of the control device, and
  • FIG. 2 shows a side view, partially broken away, of the control device according to FIG. 1.

Die Figuren 1 und 2 zeigen eine Steuervorrichtung für Spitalbetten mit einem Gehäuse 1, bestehend aus einem Gehäuseunterteil 3 und Gehäuseoberteil 2, die durch nicht dargestellte Schrauben miteinander verbunden sind, mit einer Anzahl von pneumatischen Tastschaltern 4, die jeweils paarweise nebeneinanderliegend angeordnet und funktionsmässig zugeordnet sind und mit einer Anzahl von Verriegelungsorganen 5, die zwischen zwei zugeordneten Tastschaltern 4 schwenkbar angeordnet sind. Hierzu sind im Ober- und Unterteil 2, 3 des Gehäuses 1 Lagerabschnitte 6 vorgesehen. Das Verriegelungsorgan 5 hat eine Achse 7, die in einem Lagerabschnitt 6 gelagert ist, und zwei Lappen 8,9, die diametral von der Achse 7 abstehen und einstückig mit dieser ausgebildet sind. Ferner ist im Oberteil 2 die Lagerbohrung nach aussen offen und die Stirnfläche der Achse 7 ist mit einem Eingriffsmittel 10 versehen, in die ein nicht dargestelltes Handhabungsorgan (Steckschlüssel) von Hand einsetzbar ist, um das Verriegelungsorgan 5 zu drehen. Da die Eingriffsmittel 10 von aussen sichtbar sind, kann abgelesen werden, ob die zugeordneten Tastschalter 4 verriegelt sind oder nicht.Figures 1 and 2 show a control device for hospital beds with a housing 1, consisting of a lower housing part 3 and upper housing part 2, which are connected to each other by screws, not shown, with a number of pneumatic pushbuttons 4, which are arranged in pairs next to each other and functionally assigned and with a number of locking elements 5, which are arranged pivotably between two assigned pushbuttons 4. For this purpose, 1 bearing sections are in the upper and lower part 2, 3 of the housing 6 provided. The locking member 5 has an axis 7, which is mounted in a bearing section 6, and two tabs 8, 9, which protrude diametrically from the axis 7 and are formed integrally therewith. Furthermore, in the upper part 2, the bearing bore is open to the outside and the end face of the axis 7 is provided with an engagement means 10, into which a handling element (socket wrench), not shown, can be inserted by hand in order to rotate the locking element 5. Since the engagement means 10 are visible from the outside, it can be read whether the assigned pushbuttons 4 are locked or not.

Der Tastschalter 4 enthält einen Einweg-Arbeitskolben 16 mit Rückstellfunktion und einen Tastknopf 12. Der Arbeitskolben 16 sitzt in einem einseitig offenen Zylinder 13 mit einem Anschlussstutzen 14 für einen Schlauch 15 (Figur 1) und mit seitlichen Ausnehmungen, um den Tastschalter zu entlüften. Der Kolben 16 liegt abdichtend an der Innenwandung des Zylinders 14 an. Eine Druckfeder 18, die zwischen dem Boden des Zylinders 13 und dem Kolben 16 angeordnet ist dient dazu, den Kolben 16 und den Tastknopf 12 zurückzustellen.The pushbutton switch 4 contains a one-way working piston 16 with reset function and a pushbutton 12. The working piston 16 is seated in a cylinder 13 open on one side with a connecting piece 14 for a hose 15 (FIG. 1) and with lateral recesses in order to vent the pushbutton switch. The piston 16 lies sealingly against the inner wall of the cylinder 14. A compression spring 18, which is arranged between the bottom of the cylinder 13 and the piston 16, serves to reset the piston 16 and the pushbutton 12.

Der Tastknopf 12 ist eine Kappe mit viereckiger Grundform. Am offenen Ende hat der Tastknopf 12 einen Flansch 21. Ferner ist innerhalb des Knopfes 12 ein Stössel 22 angeformt, an dem der Kolben 16 anliegt.The button 12 is a cap with a square basic shape. At the open end, the pushbutton 12 has a flange 21. Furthermore, a plunger 22, against which the piston 16 rests, is formed inside the knob 12.

Die zwei Lappen 8,9 des Verriegelungsorganes 5 liegen in der Betriebsstellung des Verriegelungsorgans 5 unterhalb des Flansches 21 des Tastknopfes 12 am Zylinder 13 an. Diese Lappen 8,9 dienen in dieser Stellung als Anschlag für den Tastknopf 12, wodurch die Eindrückbewegung des Tastknopfes blockiert wird, und die Signalabgabe verhindert wird. Da der Tastenknopf eine viereckige Form hat, wird er lagestabil im Gehäuseoberteil 2 geführt.In the operating position of the locking member 5, the two tabs 8, 9 of the locking member 5 rest against the cylinder 13 below the flange 21 of the pushbutton 12. In this position, these tabs 8, 9 serve as a stop for the pushbutton 12, as a result of which the push-in movement of the pushbutton is blocked and the signal output is prevented. Since the button has a square shape, it is guided in a stable position in the upper housing part 2.

Die vorstehend beschriebenen Signalgeber sind pneumatische Tastschalter mit Luft als Signalmedium. Um die Signalabgabe bei elektrischen Tastschaltern zu verhindern, kann dies auf die gleiche Art und Weise erfolgen.The signal transmitters described above are pneumatic pushbuttons with air as the signal medium. In order to prevent the signal output from electrical pushbuttons, this can be done in the same way.
