Abstract

The hospital bed, with a height-adjustable frame on wheels, has a brake handle (36) to be moved between braked (42) and release (40) settings. When the bed is lowered (52) to the lowest position, a bed section (20,24) automatically trips the brake handle into the braked setting, where a brake component presses against the floor (50).

Description

Die Erfindung betrifft ein Bett, bei dem es sich insbesondere um ein Kranken- oder Pflegebett handelt.The invention relates to a bed, which is in particular a hospital or nursing bed.

Kranken- bzw. Pflegebetten sind im Regelfall höhenverstellbar, um dem Kranken- bzw. Pflegepersonal die Versorgung eines Patienten bzw. Probanden zu erleichtern. Derartige Betten verfügen im Regelfall über Seitenteile beidseitig der Liegefläche, die verhindern sollen, dass der Proband aus dem Bett fällt.Health or nursing beds are usually adjustable in height to facilitate the care of a patient or volunteers. Such beds usually have side panels on both sides of the bed, which should prevent the subject from falling out of bed.

Es ist bekannt, dass die Probanden je nach ihrem psychischen bzw. physischen Zustand versuchen, die Seitenteile zu überwinden, um aus dem Bett zu steigen. Dabei kann der Fall eintreten, dass die Probanden beim Überwinden der Seitenteile stürzen, was mit nicht unerheblichen Verletzungsgefahren verbunden ist.It is known that subjects, depending on their mental or physical condition, try to overcome the side parts in order to get out of bed. In this case, the case may occur that the subjects fall over when overcoming the side parts, which is associated with not insignificant injury hazards.

Insoweit wünschenswert ist es, dass sich ein Kranken- bzw. Pflegebett soweit absenken lässt, dass sich die Oberkanten der Seitenteile in einer Höhe befinden, bei der die Verletzungsgefahr in dem Fall, dass der Proband das Seitengitter überwindet, nur noch gering ist. Idealerweise lässt sich das Bett soweit herabsenken, dass sich seine Liegefläche nur noch wenige Zentimeter (beispielsweise 20 bis 30 cm) über dem Untergrund befindet. In einer derart niedrigen Absenkposition kann dann sogar auf einen Seitenschutz verzichtet werden, da die Verletzungsgefahr bei einem "Fallen" aus wenigen Zentimetern kaum gegeben ist.In that regard, it is desirable that a hospital or nursing bed can be lowered so far that the upper edges of the side parts are at a level at which the risk of injury in the event that the subject overcomes the side rails, only low. Ideally, the bed can be lowered so far that its lying surface is only a few centimeters (for example, 20 to 30 cm) above the ground. In such a low lowering position can even be dispensed with a side protection, since the risk of injury in a "falling" of a few centimeters is hardly given.

Es ist bekannt, höhenverstellbare Gestelle von Kranken- bzw. Pflegebetten entweder durch teleskopierbare oder längenveränderbare vertikale Beine oder aber durch sogenannte Scherenmechanismen zu realisieren. Die Scherenmechanismen haben den Vorteil, dass sich die Betten extrem niedrig absenken lassen. Beispiele für Scherenmechanismen bei höhenverstellbaren Bettgestellen sind in DE 43 20 092 A1 , DE 44 06 784 C1 und DE 199 15 431 A1 beschrieben.It is known to realize height-adjustable frames of hospital or nursing beds either by telescopic or variable length vertical legs or by so-called scissor mechanisms. The scissors mechanisms have the advantage that the beds can be lowered extremely low. Examples of scissor mechanisms in height adjustable bedsteads are in DE 43 20 092 A1 . DE 44 06 784 C1 and DE 199 15 431 A1 described.

Die bekannten höhenverstellbaren Betten mit Scherenmechanismus bzw. Scherenhebeln weisen einen Rahmen mit Rahmenseiten- und Rahmenquerteilen auf, wobei am Rahmen kopf- und fußteilseitig verschwenkbare Beine angeordnet sind. Die Beine weisen sich auf einem Untergrund abstützende untere Enden auf, während ihre gegenüberliegenden oberen Enden verschiebbar am Rahmen geführt sind. Über einen zentrisch angeordneten Antriebsmechanismus lassen sich die Beine verschwenken, so dass das Bettgestell angehoben oder abgesenkt wird.The known height-adjustable beds with scissor mechanism or scissor levers have a frame with frame side and frame cross members, wherein on the frame head and Fußteilseitig pivotable legs are arranged. The legs have lower ends supporting a ground, while their opposite upper ends are slidably guided on the frame. A centrally arranged drive mechanism allows the legs to pivot so that the bed frame is raised or lowered.

Zur weiteren Steigerung des Komforts weisen Kranken- bzw. Pflegebetten verstellbare Liegeflächen, d.h. verstellbare Matratzenauflagevorrichtungen auf. Diese Vorrichtungen weisen einzeln verstellbare bzw. verschwenkbare Teile auf, die motorisch verstellbar sind. Der Verstellantrieb befindet sich unterhalb der Liegefläche bzw. Matratzenauflagefläche der Matratzenauflagevorrichtung. Das höhenverstellbare Gestell des Kranken- bzw. Pflegebetts darf mit diesem Verstellantrieb nicht kollidieren, was bedeutet, dass sich das Bett nur in eine Position absenken lässt, in der sich die Liegefläche in einer Höhe über dem Untergrund befindet, bei der man auf einen Seitenschutz nicht verzichten kann. Mit anderen Worten verhindert also der Verstellantrieb bei mit Scherenmechanismus ähnlichen Höhenverstellungen ausgestatteten Kranken- bzw. Pflegebetten, dass sich diese Betten bis zu einer Position möglichst nahe dem Untergrund absenken lassen.To further increase the comfort hospital or nursing beds have adjustable reclining surfaces, ie adjustable mattress support devices. These devices have individually adjustable or pivotable parts that are adjustable by motor. The adjusting drive is located below the lying surface or mattress support surface of the mattress support device. The height-adjustable frame of the hospital or nursing bed must not collide with this adjustment, which means that the bed can only be lowered into a position in which the lying surface is at a height above the ground, in which one does not have a side guard can do without. In other words, therefore, the adjustment prevents equipped with scissor mechanism similar height adjustments hospital or nursing beds, that these beds can be lowered to a position as close to the ground.

Kranken- bzw. Pflegebetten verfügen überdies über Feststellbremsen zur Arretierung gegen ein ungewolltes Verfahren der Betten, die im Regelfall über Lenk- und Laufrollen verfügen. Normalerweise sind derartige Feststellbremsen per Hand oder per Fuss zu bedienen. Hierbei besteht die Gefahr, dass das Kranken- bzw. Pflegepersonal die Feststellbremse versehentlich nicht betätigt hat, wenn das Bett abgesenkt wird bzw. vollständig abgesenkt ist. Somit kann sich das Bett ungewollt verschieben, was eine Verletzungsgefahr für den Patienten bzw. Probanden einerseits und die Gefahr von Beschädigungen von Funktionseinheiten des Bettes mit sich bringt, die im vollständig herabgesenkten Zustand mit nur geringer Bodenfreiheit oberhalb des Bodens angeordnet sind.Hospital or care beds also have parking brakes to lock against unwanted movement of the beds, which usually have steering wheels and casters. Normally, such parking brakes are to be operated by hand or by foot. There is a risk that the nursing staff accidentally did not operate the parking brake when the bed is lowered or completely lowered. Thus, the bed can move unintentionally, causing a risk of injury to the patient or subject on the one hand and the risk of damage to functional units of the bed with it, which are located in the fully lowered state with little ground clearance above the ground.

Aufgabe der Erfindung ist es, ein Bett, insbesondere Kranken- oder Pflegebett zu schaffen, das höhenverstellbar ist und bei dem die Gefahr einer ungewollten Verschiebung des Bettes über dem Untergrund, wenn sich das Bett im abgesenkten Zustand befindet, ausgeschlossen ist.The object of the invention is to provide a bed, especially hospital or nursing bed, which is adjustable in height and in which the risk of accidental displacement of the bed above the ground, when the bed is in the lowered state, is excluded.

Zur Lösung dieser Aufgabe wird mit der Erfindung ein Bett, insbesondere Kranken- oder Pflegebett vorgeschlagen, dass versehen ist mit

  • einem höhenverstellbaren Gestell zur Abstützung auf einem Untergrund,
  • einer Feststellbremse mit einem zwischen einer Bremsstellung und einer Freigabestellung bewegbaren, mit der Hand oder dem Fuß betätigbaren Betätigungsorgan und
  • mindestens einem Bremselement, das in der Bremsstellung des Betätigungsorgans gegen den Untergrund gedrückt und in der Freigabestellung des Betätigungsorgans vom Untergrund beabstandet ist,
  • wobei das Betätigungsorgan bei Erreichen der niedrigsten Stellung des Gestells von einem Element desselben automatisch in die Bremsstellung überführbar ist.
To solve this problem, a bed, in particular hospital or nursing bed is proposed with the invention that is provided with
  • a height-adjustable frame for support on a surface,
  • a parking brake with a movable between a braking position and a release position, operable by hand or foot actuator and
  • at least one braking element, which is pressed in the braking position of the actuating member against the ground and spaced in the release position of the actuating member from the ground,
  • wherein the actuator when it reaches the lowest position of the frame of an element thereof is automatically transferred to the braking position.

Das erfindungsgemäße Bett verfügt über eine Feststellbremse, die automatisch betätigt wird, wenn sich das Bett in seiner niedrigsten Höhenposition befindet. Dies wird erfindungsgemäß dadurch realisiert, dass das von Hand oder per Fuß betätigbare Betätigungsorgan der Feststellbremse von einem Element des höhenverstellbaren Gestells automatisch in die Bremsstellung überführt wird, wenn das Bett bis in die unterste Position abgesenkt ist.The bed according to the invention has a parking brake which is automatically actuated when the bed is in its lowest height position. This is inventively realized in that the manually or by foot operable actuator of the parking brake is automatically transferred from an element of the height-adjustable frame in the braking position when the bed is lowered to the lowest position.

Der Vorteil des erfindungsgemäßen Systems besteht darin, dass ein und dieselbe Bremse zum Feststellen des Bettes sowohl im angehobenen Zustand, in dem die Feststellbremse per Hand oder per Fuß betätigt werden kann, als auch in der niedrigsten Position, und zwar dann automatisch, genutzt werden kann (Vorbremsstellung). In der niedrigsten Position kann das Betätigungsorgan per Fuß oder Hand weiter betätigt werden, um das Bremselement noch stärker gegen den Untergrund zu drücken. In dieser Endbremsstellung verharrt das Bremselement automatisch und kann durch Lösen des Betätigungsorgans aus der Endbremsstellung wieder zurückbewegt werden.The advantage of the system according to the invention is that one and the same brake can be used to lock the bed both in the raised state, in which the parking brake can be operated by hand or by foot, as well as in the lowest position, and then automatically (Vorbremsstellung). In the lowest position, the actuator can be further operated by foot or hand to press the brake element even more against the ground. In this Endbremsstellung the brake element remains automatically and can be moved back by releasing the actuator from the Endbremsstellung.

Eine mögliche vorteilhafte Ausgestaltung der Erfindung ist dadurch gegeben, dass das Gestell einen Rahmen und an diesem gelagerte längenveränderbare und/oder verschwenkbare Beine aufweist, dass an mindestens einem der Beine oder zwischen zwei Beinen das mindestens eine Bremselement angeordnet ist und dass das Betätigungsorgan in seiner Freigabestellung in den Verfahrweg hineinragt, längs dessen sich ein Element des Gestells beim Absenken bis in die niedrigste Stellung bewegt.A possible advantageous embodiment of the invention is given by the fact that the frame has a frame and mounted on this variable-length and / or pivotable legs that at least one of the legs or between two legs, the at least one brake element is arranged and that the actuating member in its release position protrudes into the travel, along which an element of the frame moves when lowering to the lowest position.

Schließlich ist es zweckmäßig, wenn das Gestell Laufrollen aufweist und wenn zumindest eine der Laufrollen bei gegen den Untergrund drückendem Bremselement gegenüber dem Untergrund angehoben ist. Vorteilhaft ist ferner die Verwendung eines Kniehebelmechanismus zum Bewegen des Bremselements gegen den Untergrund, da das Bremselement in seiner Endbremsstellung selbsttätig in dieser Position verbleibt.Finally, it is expedient if the frame has rollers and if at least one of the rollers is lifted when pressed against the ground brake element against the ground. It is also advantageous to use a toggle mechanism for moving the brake element against the ground, since the brake element automatically remains in this position in its Endbremsstellung.

Fig. 1 zeigt ganz generell den Aufbau eines höhenverstellbaren, verfahrbaren Kranken- bzw. Pflegebetts 10, das ein (Unter-)Gesteil 12 aufweist und mit einer verstellbaren Matratzenauflagevarrichtung 14 (in Fig. 1 nur teilweise dargestellt) versehen ist. Das höhenverstellbare Untergestell 12 ist in diesem Ausführungsbeispiel nach Art eines Scherenmechanismus ausgebildet, auf den es im Rahmen dieser Erfindung jedoch nicht ankommt.Fig. 1 shows quite generally the structure of a height-adjustable, movable hospital or nursing bed 10, which has a (lower) part 12 and with an adjustable Matratzenauflagevarrichtung 14 (in Fig. 1 only partially shown) is provided. The height-adjustable base 12 is formed in this embodiment in the manner of a scissors mechanism, which does not matter in the context of this invention.

In dem Ausführungsbeispiel weist das Untergestell 12 einen Rahmen 16 auf, der Rahmenseitenteile 18 und Rahmenquerteile 20 aufweist, an denen sich ein Kopfteil 22 und ein Fußteil 24 befinden. Unterhalb des Rahmens 16 befinden sich schwenkbar gelagerte und geführte Beine 26,28, die an ihren unteren Ende Laufrollen 30 bzw. Lenkrollen 32 aufweisen. Im Bereich der Lenkrollen 32, die in diesem Ausführungsbeispiel an dem dem Fußteil 24 zugeordneten Beinen 28 angeordnet sind, befindet sich eine Feststellbremse 34, die ein Betätigungsorgan im Form eines Betätigungsbügels 36 aufweist, an dem zwei Bremselemente 38 aus Gummi angeordnet sind und der um eine Achse schwenkbar an den Beinen 28 gelagert ist.In the exemplary embodiment, the underframe 12 has a frame 16 which has frame side parts 18 and frame cross members 20, on which a head part 22 and a foot part 24 are located. Below the frame 16 are pivotally mounted and guided legs 26,28 having at their lower end rollers 30 and castors 32. In the area of the castors 32, which are arranged in this embodiment on the foot part 24 associated legs 28, there is a parking brake 34 having an actuator in the form of an actuating bracket 36 to which two brake elements 38 are arranged in rubber and pivotable about an axis on the legs 28th is stored.

In den Fign. 2 und 3 ist zu erkennen, dass der Betätigungsbügel 36 zwischen einer Freigabestellung (Fig. 2) und einer Bremsstellung (Fig. 3) schwenkbar ist.In the Fign. 2 and 3 it can be seen that the actuating bow 36 is pivotable between a release position (FIG. 2) and a braking position (FIG. 3).

Wie insbesondere anhand der Fign. 5 und 6 zu erkennen ist, sind die Bremselenente 38 exzentrisch um die Achse 44 drehbar gelagert. Die Bremselemente 38 weisen eine Vorwölbung 46 auf, die je nach Stellung des Betätigungsbügels 36 entweder oberhalb des Untergrunds 50 (siehe Fig. 5 - Freigabeposition) oder aber gegen den Untergrund 50 gedrückt ist (siehe Fig. 6 - Bremsstellung). In der Position gemäß Fig. 6 sind die Lenkrollen 32 gegenüber dem Untergrund 50 angehoben, so dass das Bett 10 auf den Bremselementen 38 ruht.As particularly with reference to FIGS. 5 and 6 can be seen, the brake elements 38 are mounted eccentrically about the axis 44 rotatably. The brake elements 38 have a protrusion 46 which, depending on the position of the actuating clip 36, is pressed either above the substrate 50 (see FIG. 5 - release position) or against the substrate 50 (see FIG. 6 - braking position). In the position shown in FIG. 6, the castors 32 are raised relative to the ground 50, so that the bed 10 rests on the brake elements 38.

Anhand der Fign. 2 und 3 ist zu erkennen, dass sich der Betätigungsbügel 36 in seiner Freigabestellung 40 (siehe Fig. 2) innerhalb des Verfahrweges 52 befindet, längs dessen sich beispielsweise das hintere Rahmenquersteil 20 oder das Fußteil 24 oder ein anderes Element des Rahmens 16 bei dessen Höhenverstellung bewegt.Based on the Fign. 2 and 3 it can be seen that the actuating bow 36 is in its release position 40 (see FIG. 2) within the travel path 52, along which, for example, the rear frame transverse part 20 or the foot part 24 or another element of the frame 16 in the height adjustment emotional.
