Abstract

1. Support for invalids'beds, in particular a stretcher support or treatment table in ambulances or the like, with pneumatic springing which optionally also permits vertical adjustment of the sprung support part, and also with a possibility for blocking the spring support part to render it vertically immovable, characterized in that the sprung support part (2) is connected with a rod part (12, 13') which executes a longitudinal displacement during sprung strokes of the sprung support part (2) and can be fixed relative to the non-sprung support part (21) or the floor by means of a pneumatically actuatable brake (17), which engage with its brake jaws (31) in chuck-like manner around the rod part (12, 23') which cooperates with it.

Description

Die Erfindung betrifft ein Krankenliegengestell, insbesondere eine Krankentragenbühne oder einen Behandlungstisch od.dgl. in Ambulanzfahrzeugen, mit pneumatischer Federung, welche gegebenenfalls auch eine Höhenverstellung des gefederten Gestellteiles zuläßt.The invention relates to a bed frame, in particular a stretcher or a treatment table or the like. in ambulance vehicles, with pneumatic suspension, which may also allow height adjustment of the sprung frame part.

Entsprechende Krankentragenbühnen sind beispielsweise aus der DE-OS 29 36 617 bekannt und zeichnen sich bei einfacher Konstruktion durch hohen Federungskomfort aus. Insbesondere läßt sich auch gewünschtenfalls eine stark progressive Federung erzielen.Corresponding stretcher platforms are known for example from DE-OS 29 36 617 and are characterized by a simple construction by high suspension comfort. In particular, a highly progressive suspension can also be achieved if desired.

Zur Durchführung einer Herzmassage muß allerdings der zu behandelnde Patient auf einer festen, nicht federnden Unterlage liegen. Deshalb muß an Krankentragenbühnen die Möglichkeit vorgesehen werden, die Federung gegebenenfalls ausschalten zu können. Bei pneumatisch gefederten Krankentragenbühnen wird dazu die Bühne oftmals in ihre unterste Endlage abgesenkt. Abgesehen davon, daß dazu vergleichsweise viel Zeit benötigt wird, kann die Herzmassage nicht in einer für das Sanitätspersonal günstigen Arbeitshöhe am Patienten durchgeführt werden. Aus diesem Grunde wurde schon vorgesehen, die Tragenbühne aus einer angehobenen Lage auf einsetzbare Stützen abzusenken, welche den Patienten auf einer für die Herzmassage optimalen Arbeitshöhe halten. Jedoch ist auch hier die entsprechende Bedienung der Krankentragenbühne relativ zeitraubend und darüber hinaus umständlich. Deshalb ist es Aufgabe der Erfindung, eine Krankentragenbühne der eingangs angegebenen Art dahingehend zu verbessern, daß eine Arretierung der im Normalfalle abgefederten Liegefläche in jeder gewünschten und durch die Konstruktion der pneumatischen Federung zugelassenen Höhe bei einfachster Bedienung möglich ist.To carry out a cardiac massage, however, the patient to be treated must lie on a firm, non-resilient surface. Therefore, the possibility must be provided on stretcher platforms, if necessary, to be able to switch off the suspension. In the case of pneumatically suspended stretcher platforms, the platform is often lowered to its lowest end position. Apart from the fact that a comparatively large amount of time is required for this, the cardiac massage cannot be carried out on the patient at a working height which is favorable for the medical personnel. For this reason, it has already been planned to lower the stretcher platform from a raised position onto insertable supports which keep the patient at an optimal working height for the cardiac massage. However, operating the stretcher platform here is also relatively time-consuming and cumbersome. Therefore, it is an object of the invention to improve a stretcher platform of the type mentioned in such a way that a locking of the lying surface cushioned in the normal case is possible at any desired height and permitted by the construction of the pneumatic suspension with simple operation.

Diese Aufgabe wird dadurch gelöst, daß das gefederte Gestellteil mit einem Gestängeteil verbunden ist, welches bei Federungshüben des gefederten Gestellteiles eine Längsverschiebung ausführt und mittels einer pneumatisch betätigbaren Bremse gegenüber dem ungefederten Gestellteil feststellbar ist.This object is achieved in that the spring-loaded frame part is connected to a linkage part which executes a longitudinal displacement in the case of suspension strokes of the spring-loaded frame part and can be determined by means of a pneumatically actuated brake with respect to the unsprung frame part.

Die Erfindung geht von dem allgemeinen Gedanken aus, daß das gefederte Gestellteil bei Krankentragenbühnen u.dgl. zur Verhinderung von Schlingerbewegungen mit vertikaler Führung abgestützt ist, so daß lediglich vertikale Bewegungen der Liegefläche zugelassen werden und dieselbe auch beim Einfedern ihre eingestellte Horizontallage oder Schrägstellung (z.B. Kopf-Tief-Lage) unverändert beibehält; aufgrund dieser Bauweise genügt es, ein einziges unmittelbar oder über ein Hubgestell mit dem gefederten Gestellteil verbundenes Gestängeteil, welches bei Federungshüben eine Längsverschiebung erleidet, zur Ausschaltung der Federung zu arretieren. Dabei kann die Bremse bevorzugt mit einem Gestängeteil des pneumatischen Federungsaggregates zusammenwirken, beispielsweise mit der Kolbenstange eines zur federnden Abstützung des Tragengestelles dienenden Kolben-Zylinder-Aggregates oder auch mit einem Stößel, welcher beispielsweise federnd auf einer vom pneumatischen Medium gestützten Membrane oder einem Pneumatikbalg abgestützt ist.The invention is based on the general idea that the sprung frame part on stretcher platforms and the like. is supported with vertical guidance to prevent roll movements, so that only vertical movements of the lying surface are permitted and the same maintains its set horizontal position or inclined position (e.g. head-down position) unchanged even when deflected; due to this design, it is sufficient to lock a single rod part which is connected directly or via a lifting frame to the sprung frame part and which undergoes a longitudinal displacement during suspension strokes, in order to switch off the suspension. The brake can preferably cooperate with a linkage part of the pneumatic suspension unit, for example with the piston rod of a piston-cylinder unit serving to provide resilient support for the support frame, or also with a tappet which is resiliently supported, for example, on a diaphragm supported by the pneumatic medium or a pneumatic bellows .

Gemäß einer zweckmäßigen Ausgestaltung der Erfindung umgreift die Bremse das mit ihr zusammenwirkende Gestängeteil mittels ihrer Bremsbacken nach Art eines Spannfutters, wobei die Bremsbacken vorzugsweise mit einem dieselben betätigenden Schieberteil mittels Keilflächen zusammenwirken. Bei derartiger Anordnung können auch bei geringen Pneumatikdrucken und entsprechend spitzwinklig angeordneten Keilflächen sehr hohe Bremskräfte erreicht werden.According to an expedient embodiment of the invention, the brake engages around the rod part interacting with it by means of its brake shoes in the manner of a chuck, the brake shoes preferably interacting with a slide part actuating the same by means of wedge surfaces. With such an arrangement, very high braking forces can be achieved even at low pneumatic pressures and corresponding wedge surfaces arranged at an acute angle.

Zweckmäßigerweise wird dabei das Schieberteil in die Bremse betätigender Richtung pneumatisch und in die Bremse lösender Richtung mittels gespannter Feder beaufschlagt, so daß das die Bremse betätigende Pneumatikorgan lediglich während einer Herzmassage oder einer sonstigen die feste Lagerung des Patienten erfordernden Behandlung unter Druck gesetzt werden muß und die Bremse bei Nichtgebrauch sicher in ihrer unwirksamen Stellung gehalten wird, ohne unerwünschte Reibung zu verursachen.Advantageously, the slide part is actuated pneumatically in the brake actuating direction and in the brake releasing direction by means of a tensioned spring, so that the pneumatic actuator actuating the brake only has to be pressurized during a cardiac massage or other treatment requiring the fixed positioning of the patient and the Brake is held securely in its inactive position when not in use, without causing undesirable friction.

Einander entsprechende Teile haben in allen Figuren gleiche Bezugszeichen.Corresponding parts have the same reference numerals in all figures.

Nach Fig. 1 ist auf dem Boden eines Krankenfahrzeuges eine Krankentragenbühne 1 angeordnet, welches im wesentlichen aus einem Rahmengestell 2 besteht, dessen beide Längsträger 3 als U-Schienen ausgebildet sind, in denen ein einen oberen Gestellrahmen bildender Lagerungsschlitten 4 in Längsrichtungrichtung verschiebbar mittels Rollen 5 geführt ist.According to Fig. 1, a stretcher platform 1 is arranged on the floor of an ambulance, which essentially consists of a frame 2, the two longitudinal beams 3 of which are designed as U-rails, in which a positioning slide 4 forming an upper frame can be displaced in the longitudinal direction by means of rollers 5 is led.

Der Tragenlagerungsschlitten 4 dient zur Aufnahme einer Krankentrage 6, die ihrerseits mittels ihrer Füße 7 auf den Längsschienen des Schlittens 4 aufruht und auf demselben arretiert werden kann.The stretcher sled 4 serves to accommodate a stretcher 6, which in turn rests on the longitudinal rails of the sled 4 by means of its feet 7 and can be locked thereon.

Das Rahmengestell 2 und damit die gesamte Krankentragenbühne 1 ist an ihrem der nicht dargestellten Hecktür des Krankenfahrzeuges zugewandten hinteren Ende in einem Gelenk 8 mit waagerechter Querachse am Boden schwenkbar gelagert und an seinem vorderen Ende durch ein Scherensystem 9, welches z.B. aus zwei beiderseits der lotrechten Mittelebene der Krankentragenbühne angeordnete Lenkerpaare gebildet wird, in Höhenrichtung geführt bzw. gegen seitliches Ausweichen gesichert. Bei entsprechend stabiler Ausbildung des Gelenkes 8 kann das Scherensystem 9 gegebenenfalls auch entfallen.The frame 2 and thus the entire stretcher platform 1 is pivotally mounted on its rear end facing the rear door of the ambulance, not shown, in a joint 8 with a horizontal transverse axis on the floor and at its front end by a scissor system 9, which e.g. is formed from two pairs of links arranged on both sides of the vertical central plane of the stretcher platform, guided in the vertical direction or secured against lateral evasion. With a correspondingly stable design of the joint 8, the scissors system 9 may also be omitted.

Zur Abfederung des Tragengestelles dient eine pneumatische Federung 10, welche einen mit dem Rahmengestell 2 verbundenen Stößel 12 aufweist, welcher in an sich bekannter Weise auf der pneumatisch abgestützten Membrane 13 eines pneumatischen Druckgefäßes 14 abgestützt ist. Dem Innenraum des Druckgefäßes 14 kann über eine Leitung 15 pneumatisches Medium von einer nicht dargestellten Druckquelle zugeführt werden.A pneumatic suspension 10, which has a plunger 12 connected to the frame 2, which is supported in a manner known per se on the pneumatically supported membrane 13 of a pneumatic pressure vessel 14 serves to cushion the support frame. Pneumatic medium can be supplied to the interior of the pressure vessel 14 via a line 15 from a pressure source, not shown.

Das Druckgefäß 14 ist an einem am Boden montierten Bock 16 befestigt, an dem außerdem eine pneumatisch betätigbare Bremse 17 angeordnet ist, die mit dem Stößel 12 zusammenwirkt. Bei Arretierung des Stößels 12 wird das Rahmengestell 2 unfederbar festgehalten.The pressure vessel 14 is fastened to a bracket 16 mounted on the floor, on which a pneumatically actuable brake 17 is also arranged, which cooperates with the tappet 12. When the plunger 12 is locked, the frame 2 is held in place without springing.

Bei der in Fig. 2 dargestellten Krankentragenbühne ist das Rahmengestell 2 mittels eines Scherengestelles 20 abgestützt, dessen Scherenarme an ihren in der Zeichnung linken Enden am Rahmengestell 2 bzw. einem Sockelrahmen 21 um Querachsen schwenkbar gelagert sind, während die anderen Enden der Scherenarme am Rahmengestell 2 sowie am Sockelrahmen 21 in Führungskulissen 22 schwenk- und verschiebbar gelagert sind. Damit kann das Scherengestell 20 mittels eines pneumatischen Kolben-Zylinder-Aggregates 23, welches mit einer nicht dargestellten pneumatischen Druckquelle verbunden und zwischen dem einen Scherenarm des Scherengestelles 20 sowie dem Boden bzw. dem Sockelrahmen 21 angeordnet ist, in verschiedene Höhen verstellt werden, wobei aufgrund der Kompressibilität des Pneumatikmediums in jeder Höheneinstellung eine Federung des Rahmengestelles 2 möglich bleibt.In the stretcher platform shown in Fig. 2, the frame 2 is supported by a scissor frame 20, the scissor arms are pivotally mounted on their left ends in the drawing on the frame 2 or a base frame 21 about transverse axes, while the other ends of the scissor arms on the frame 2nd and on the base frame 21 are pivotally and displaceably mounted in guide links 22. The scissor-type frame 20 can thus be adjusted to different heights by means of a pneumatic piston-cylinder unit 23, which is connected to a pneumatic pressure source (not shown) and is arranged between the one scissor arm of the scissor-type frame 20 and the floor or the base frame 21, due to the compressibility of the pneumatic medium in any height setting, a suspension of the frame 2 remains possible.

Zur Ausschaltung der Federung ist hier am Zylinder des Kolben-Zylinder-Aggregates die pneumatisch betätigte Bremse 17 angeordnet, welche mit der Kolbenstange 23' des Kolben-Zylinder-Aggregates zusammenwirkt.To switch off the suspension, the pneumatically actuated brake 17 is arranged on the cylinder of the piston-cylinder unit, which cooperates with the piston rod 23 'of the piston-cylinder unit.

Gemäß Fig. 3 besitzt die pneumatisch betätigbare Bremse ein ringförmiges Gehäuse 25, dessen axiale Öffnung vom Stößel 12 (vgl. Fig. 1) bzw. der Kolbenstange 23' (vgl. Fig.2) durchsetzt wird. Innerhalb des Gehäuses 25 befindet sich ein volumenveränderlicher Ringraum 26, welcher mittels eines ringförmigen Kolbens 27 abgeschlossen ist, der innerhalb des Gehäuses 25 verschiebbar angeordnet ist. Eine Rückstellfeder 28 sucht den Ringkolben 27 in Fig. 3 nach oben in eine Ruhelage zu schieben, während in den Ringraum 26 eingeleitetes Pneumatikmedium den Ringkolben 27 gegen die Kraft der Feder 28 nach unten zu schieben vermag. Am Kolben 27 ist ein Zylinderteil 29 angeordnet, welches mittels entsprechender Lagerschalen od.dgl. zur Lagerung von Kugeln 30 dient, die bei Verschiebung des Kolbens 27 über die Rückseite von Bremskeilen 31 geschoben werden, die an der inneren Umfangswand des Gehäuses 25 angeordnet sind und aufgrund ihres keilförmigen Querschnittes bei Verschiebung der Kugeln 30 nach aufwärts zunehmend gegen die Kolbenstange 23' bzw. den Stößel 12 angedrückt werden und denselben unbeweglich gegenüber dem Gehäuse 25 festhalten. Wird der Kolben bei Druckverminderung im Ringraum 26 durch die Feder 28 wiederum zurückgeschoben, können die von den Kugeln 30 nunmehr freigegebenen Bremskeile 31 unter Einwirkung nicht dargestellter Rückholfedern von der Kolbenstange 23' bzw. dem Stößel 12 abheben, d.h. eine Federung der Krankentragenbühnen ist wiederum möglich.According to FIG. 3, the pneumatically actuable brake has an annular housing 25, the axial opening of which is penetrated by the plunger 12 (see FIG. 1) or the piston rod 23 '(see FIG. 2). Inside the housing 25 there is an annular space 26 which can be changed in volume and which is closed off by means of an annular piston 27 which is arranged displaceably within the housing 25. A return spring 28 tries to push the annular piston 27 upward into a rest position in FIG. 3, while pneumatic medium introduced into the annular space 26 is able to push the annular piston 27 downward against the force of the spring 28. On the piston 27, a cylinder part 29 is arranged, which by means of ent speaking bearing shells or the like. serves to support balls 30, which are pushed over the back of brake wedges 31 when the piston 27 is displaced, which are arranged on the inner peripheral wall of the housing 25 and, due to their wedge-shaped cross-section, when the balls 30 are displaced upwards increasingly against the piston rod 23 ' or the plunger 12 are pressed and hold it immovably with respect to the housing 25. If the piston is pushed back by the spring 28 when the pressure in the annular space 26 is reduced, the brake wedges 31 now released by the balls 30 can lift off from the piston rod 23 'or the plunger 12 under the action of return springs (not shown), ie suspension of the stretcher platforms is again possible .
