Abstract

The pivot device has a cross axis (52) crossways to the longitudinal direction of the bed (2), which runs outside the centre of gravity of the bed, pref. in the vicinity of the head part (51). The largest part of the bed extending in the night position into the free space is held by the pivot device engaging on the cross axis. A roller lever (15) connected with wagon structure with a curve disc (14) firmly connected to the pivot-fold bed (2) forms a stop for the night position. The pivot device has two parts for beds (1, 2) arranged one above the other, which are operable simultaneously by a common, unlockable and securable bed unlocking grip (3).

Description

Die Erfindung betrifft eine Schwenkeinrichtung für Betten, welche über die Betätigung einer Entriegelungs- und Arretierungsmechanik in eine benutzbare Nachtstellung und in eine raumsparende Tagstellung gebracht und jeweils arretiert werden können.The invention relates to a pivoting device for beds, which can be brought into a usable night position and into a space-saving day position and locked in each case by actuating an unlocking and locking mechanism.

Einrichtungen dieser Art werden in Eisenbahnschlafwagen benutzt, wobei die Betten tagsüber in aufgeklapptem Zustand in Nischen verstaut und für die Nacht in die horizontale Liegestellung gebracht werden. In der einfachsten Form weisen diese Einrichtungen Scharniere an der Längsseite eines Bettes auf, um deren Drehachsen die Liegen an eine Wand hochgeklappt und zum Liegen entsprechend um 90° abgeklappt werden können. In der aufgeklappten Stellung wird mit einfachen Mitteln, z.B. Vorreiber, eine Arretierung ermöglicht und im abgeklappten Zustand können beispielsweise Bänder oder Klappscharniere die horizontale Lage sichern.Devices of this type are used in railway sleeping cars, with the beds stowed in niches during the day when opened and brought into the horizontal lying position for the night. In the simplest form, these devices have hinges on the long side of a bed, about the axes of rotation of which the beds can be folded up against a wall and folded down by 90 ° for lying. In the opened position, simple means, e.g. Sash lock, which enables locking and, when folded down, hinges or hinges, for example, can secure the horizontal position.

Die CH-Patentschrift Nr. 517 610 beschreibt und zeigt einen Eisenbahnschlafwagen mit Klappbetten der beschriebenen Art. An den Abteilwänden sind übereinander zwei Klappbetten angeordnet, die um die Längsachse hoch- und abgeklappt werden können. Die Betten weisen (gem. Fig. 3) stirnseitig vorstehende Führungs- und Tragbolzen auf, die mit Kulissenführungen und Tragbeschlägen verbunden sind. Die Form der Kulissenführung ermöglicht die Verwendung des unteren Bettes als Rückenlehne und das Auf- und Abklappen des oberen Bettes in noch zugänglicher Höhe.Swiss Patent No. 517 610 describes and shows a railway sleeping car with folding beds of the type described. Two folding beds are arranged one above the other on the compartment walls, which can be folded up and down about the longitudinal axis. The beds have (according to FIG. 3) projecting guide and support bolts on the end face, which are connected to link guides and support fittings. The shape of the link guide enables the lower bed to be used as a backrest and the upper bed to be opened and closed at a still accessible height.

Bei dieser Konstruktion werden die Liegeflächen am Stück umgeklappt und bleiben beide am Stück von ihrer Rückseite aus sichtbar, was aus ästhetischen Gründen unbefriedigend ist. Ausserdem können die Betten nur längsseitig an der Wand befestigt werden, wofür bei Doppelstockwagen der Platz nicht ausreicht und was eine ansprechende Innenraumgestaltung ebenfalls erschwert. Ferner ist ein nicht unbedeutender Kraftaufwand nötig, um die entsprechenden Umstellungen für Tag- und Nachtpositionen vorzunehmen.With this construction, the lying surfaces are folded down in one piece and both remain visible from the back, which is unsatisfactory for aesthetic reasons. In addition, the beds can only be attached to the wall on the long side, which is not enough space for double-deck cars and which also complicates an attractive interior design. Furthermore, a not insignificant effort is necessary to make the appropriate changes for Day and night positions.

Es ist deshalb die Aufgabe der vorliegenden Erfindung, eine Schwenkmechanik zu schaffen, welche die genannten Nachteile nicht aufweist und unter Last eine stabile Lagefixierung eines nur an einem Endteil seitlich gehaltenen Bettes ermöglicht, dessen restlicher längerer Teil frei in den Raum herausragt. Dabei soll, bei leichter Bedienbarkeit, das spezielle Lichtraumprofil bei Doppelstockwagen optimal ausgenützt werden können.It is therefore the object of the present invention to provide a swivel mechanism which does not have the disadvantages mentioned and, under load, enables a bed to be held in a stable position only at one end part, the remaining longer part of which projects freely into the space. At the same time, the special clearance profile for double-decker carriages should be able to be optimally used while being easy to use.

Diese Aufgabe wird durch die in den Ansprüchen gekennzeichnete und in den Figuren dargestellte Erfindung gelöst.This object is achieved by the invention characterized in the claims and shown in the figures.

Die Erfindung hat u.a. den Vorteil, dass für zwei Betten nur eine einzige Auslöse- und Sicherungsmechanik benötigt wird und dass durch eine Federausbalancierung minimale Kräfte für die Umstelloperationen benötigt werden.The invention has i.a. the advantage that only one release and safety mechanism is required for two beds and that spring balancing means that minimal forces are required for the changeover operations.

Ein weiterer Vorteil der Erfindung liegt darin, dass das Umstellen der Betten in die Tagstellung und umgekehrt in sinnfälligerweise nur durch einfaches Ziehen und Stossen an Entriegelungsgriffen ausgeführt werden kann, ohne dass komplizierte Bedienungsanleitungen beachtet werden müssen.Another advantage of the invention is that the beds can be switched over to the day position and vice versa in a logical manner only by simply pulling and pushing on the release handles without having to observe complicated operating instructions.

In der Fig. 1 ist mit 20 ein Doppelstockschlafwagen bezeichnet. Im oberen und im unteren Stock sind je ein unteres Schwenkbett 1 und ein oberes Schwenkklappbett 2 angeordnet, in der Folge genannt unteres Bett 1 und oberes Bett 2. Diese zwei Betten 1 und 2 unten und oben können je hinter eine Nischenseitenwand 41 weggeschwenkt werden. Die Nischenseitenwand 41 ist links vorn mit einer Nischenwandkante 38 abgeschlossen. Die unteren Betten 1 bestehen aus einer einstückigen Liegefläche und weisen links aussen seitlich einen Muschelgriff 34 auf. Die oberen Betten 2 bestehen aus einem um die Querachse drehbar gelagerten Schwenkteil 50, einem mit dem Schwenkteil 50 links durch ein Scharnier verbundenes Klappteil 37 auf der Fusseite und einem rechts mit dem Schwenkteil 50 ebenfalls beweglich verbundenes Kopfteil 51.In Fig. 1, 20 is a double-deck sleeper. A lower swivel bed 1 and an upper swivel folding bed 2 are arranged on the upper and lower floors, hereinafter referred to as lower bed 1 and upper bed 2. These two beds 1 and 2 below and above can each be swung away behind a niche side wall 41. The niche side wall 41 is closed at the front left with a niche wall edge 38. The lower beds 1 consist of a one-piece bed surface and have a shell handle 34 on the outside on the left. The upper beds 2 consist of a swivel part 50 mounted rotatably about the transverse axis, a hinged part 37 connected to the swivel part 50 on the left by a hinge on the foot side and a head part 51 likewise movably connected to the swivel part 50 on the right.

Die Schwenkmechanik besteht beim oberen Bett 2 aus einer mit dem Bett 2 starr verbundenen Kurvenscheibe 14, die seitlich an der in Richtung Kopfteil 51 aussermittigen Querachse 52 befestigt ist. Die Kurvenscheibe 14 wirkt beim Aus- und Abschwenken des Bettes 2 gegen eine mit ihr an der linken Ecke angreifende Gasdruckfeder 17 und greift mit ihrer rechten Ecke in die Klinke eines Klinkenhebels 13. Ein in die Kurvenscheibe 14 eingerasteter Rollenhebel 15 ist über ein Gestänge 12 mit dem Klinkenhebel 13 verbunden. Der Rollenhebel 15 wird von einer Gasdruckfeder 33 gesteuert, welche ihrerseits gelenkig mit einem Gestänge 11 verbunden ist. Das Gestänge 11 ist am unteren Ende mit dem Rollenhebel 15 verbunden und in der Nischenseitenwand 41 drehbar gelagert und wird von einem Mitnehmer 39 eines herausziehbaren, in einer Führung 10 gleitenden Bettenentriegelungsgriffes 3 je nach dessen Stellung in eine der beiden gezeigten Lagen gebracht. Die Bewegung der Kurvenscheibe 14 ist in den zwei Extremlagen 0° und 120° durch einen mit der Nischenwand 41 verbundenen Endanschlag 16 begrenzt.The pivot mechanism in the upper bed 2 consists of a cam plate 14 rigidly connected to the bed 2, which is attached laterally to the transverse axis 52 which is eccentric in the direction of the head part 51. The cam plate 14 acts when pivoting the bed 2 against and against a gas pressure spring 17 engaging it on the left corner and engages with the right corner in the pawl of a ratchet lever 13. A roller lever 15 which is locked in the cam plate 14 is also connected via a linkage 12 the ratchet lever 13 connected. The roller lever 15 is controlled by a gas pressure spring 33, which in turn is articulated to a linkage 11. The linkage 11 is connected at the lower end to the roller lever 15 and rotatably mounted in the niche side wall 41 and is one of Carrier 39 of a pull-out bed release handle 3 sliding in a guide 10, depending on its position, is brought into one of the two positions shown. The movement of the cam plate 14 is limited in the two extreme positions 0 ° and 120 ° by an end stop 16 connected to the recess wall 41.

Die mechanische Entriegelung und Arretierung des unteren Bettes 1 erfolgt über eine flexible mechanische Verbindung in der beispielhaften Form eines Zug-/Druckkabels 19, welches beim unteren Bett 1 einen Rollenhebel 21 betätigt. Der Rollenhebel 21 wird zusätzlich von einer Gasdruckfeder 22 gegen die Kontur eines mit dem Bett 1 starr verbundenen Sperrhebels 23 gedrückt. Ferner ist der Rollenhebel 21 über ein vertikales Gestänge 24 mit einer etwas unterhalb angebrachten Rollenschwinge 25 mechanisch verbunden. Der Sperrhebel 23 hat im Zusammenwirken mit dem Rollenhebel 21 die Aufgabe, das Bett 1 in der Nachtstellung und im Zusammenwirken mit der Rollenschwinge 25 das Bett 1 in der Tagstellung zu arretieren. Die Betten 1 und 2 sind je am Fussende nicht unterstützt, sondern ragen frei in den Abteilraum hinein. Dennoch kann die Liegefläche auch links aussen auf dem Schwenkteil 50 und auf dem Klappteil 37 die Gewichtslast einer Person aufnehmen. Zur Ausbalancierung des Bettes 1 ist der Sperrhebel 23 mit einer Gasdruckfeder 18 verbunden.The mechanical unlocking and locking of the lower bed 1 takes place via a flexible mechanical connection in the exemplary form of a pull / push cable 19 which actuates a roller lever 21 in the lower bed 1. The roller lever 21 is additionally pressed by a gas pressure spring 22 against the contour of a locking lever 23 rigidly connected to the bed 1. Furthermore, the roller lever 21 is mechanically connected via a vertical linkage 24 to a roller rocker 25 attached somewhat below. The locking lever 23, in cooperation with the roller lever 21, has the task of locking the bed 1 in the night position and in cooperation with the roller rocker 25, the bed 1 in the day position. Beds 1 and 2 are not supported at the foot end, but protrude freely into the compartment. Nevertheless, the lying surface can also accommodate the weight load of a person on the left outside on the swivel part 50 and on the folding part 37. To balance the bed 1, the locking lever 23 is connected to a gas pressure spring 18.

Die Fig. 2, 3 und 4 werden in einem späteren Kapitel an Hand der Funktionsbeschreibung kommentiert.2, 3 and 4 are commented on in a later chapter on the basis of the functional description.

In den Fig. 5 sind weitere Einzelheiten der Schwenkmechanik für das obere Bett 2 dargestellt. In der gezeigten Stellung der Kurvenscheibe 14 befindet sich das Bett 2 in der Tag- oder 0°-Stellung, das heisst, das Bett 2 ist hinter der Nischenseitenwand 41 verstaut. Der Rollenhebel 15 dreht sich um einen in der Nischenseitenwand 41 fixierten Drehpunkt 43 und wird in der gezeigten Stellung von der am rechten Ende angreifenden Gasdruckfeder 33 nach unten gedrückt. Eine, ebenfalls rechts angeordnete Anschlagrolle 29 liegt in einer Vertiefung 42 der Kurvenscheibe 14. Eine Klinkennase 40 des Klinkenhebels 13 liegt in der Vertiefung zwischen einer Sicherungsnase 26 und einer 30°-Nase 27. Der Klinkenhebel 13 dreht sich um einen Drehpunkt 44 und weist einen nach rechts vorstehenden Schenkel 45 auf, der mit dem Zug-/Druckkabel 19 gelenkig verbunden ist. Durch das den Klinkenhebel 13 mit dem Rollenhebel 15 verbindenden und mit etwa gleichem Radius angreifenden Gestänge 12 machen der Rollenhebel 15 und der Klinkenhebel 13 synchrone Bewegungen bei einer Betätigung durch den Bettenentriegelungsgriff 3. Das Langloch links am Gestänge 12 wirkt als Freilauf gegen das Entriegeln des oberen Bettes 2 beim Anheben des unteren Bettes 1.5 further details of the pivoting mechanism for the upper bed 2 are shown. In the position of the cam plate 14 shown, the bed 2 is in the day or 0 ° position, that is to say the bed 2 is stowed behind the niche side wall 41. The roller lever 15 rotates about a pivot point 43 fixed in the niche side wall 41 and is pressed down in the position shown by the gas pressure spring 33 acting on the right end. A stop roller 29, also arranged on the right, lies in one Indentation 42 of the cam disk 14. A pawl nose 40 of the pawl lever 13 lies in the indentation between a securing nose 26 and a 30 ° nose 27. The pawl lever 13 rotates about a pivot point 44 and has a leg 45 protruding to the right, which is connected to the Train / push cable 19 is articulated. Through the linkage 12 connecting the ratchet lever 13 to the roller lever 15 and engaging with approximately the same radius, the roller lever 15 and the ratchet lever 13 make synchronous movements when actuated by the bed unlocking handle 3. The elongated hole on the left side of the linkage 12 acts as a freewheel against unlocking the upper one Bed 2 when lifting the lower bed 1.

Die Fig. 9 und 10 zeigen die Einzelheiten des Bettenentriegelungsgriffes 3. Ein an dessen oberen Ende vorstehender Auslöseknopf 4 ist über eine Schubstange 47 mit zwei hintereinander angeordneten, in einem Führungsrohr 48 gleitenden Auslösekonen 5 verbunden, die sich gegen die Kraft einer Feder 46 nach links verschieben lassen. In der Fig. 10 befindet sich der Bettenentriegelungsgriff 3 in der hineingeschobenen, die Schwenkmechanismen sichernden Stellung. Hier liegt eine, durch einen Rohrschlitz 30 eintauchende Riegelnase 7 eines Riegels 6 an der Flanke des rechten Konusses 5 an, wobei der Andruck am unteren Ende des Riegels 6, der sich um einen Drehpunkt 49 dreht, durch eine Feder 9 erzeugt wird. Wird der Bettenentriegelungsgriff 3 bei gleichzeitigem Drücken des Auslöseknopfes 4 herausgezogen, wird die Stellung gemäss Fig. 9 eingenommen, und es wird beim Herausziehen gleichzeitig das, mittels eines am linken Ende des unteren Teiles des Bettenentriegelungsgriffes 3 vorhandenen Mitnehmers 39 das obere Ende des über die Gasdruckfeder 33 (Fig. 2) mit dem Rollenhebel 15 (Fig. 2) verbundenen Gestänges 11 mitgenommen, was die Entriegelung der Schwenkmechanik für das obere und das untere Bett 2 und 1 zur Folge hat. Ohne Drücken des Auslöseknopfes 4 kann der Bettenentriegelungsgriff 3 nicht herausgezogen werden, weil dies beim Ziehen die dann an der Rückseite des linken Konus 5 anliegende Riegelnase 7 verhindert. Im herausgezogenen Zustand gemäss Fig. 9 wird der Bettenentriegelungsgriff 3 am kraftlosen Hineinrutschen durch eine von einer Klinkenfeder 31 an den linken Konus 5 angedrückte Klinke 8 gehindert, das heisst, auch das Hineinstossen des Bettenentriegelungsgriffes 3 muss mit gleichzeitigem Drücken des Auslöseknopfes 4 erfolgen. Mit 32 ist ein Anschlagbolzen bezeichnet, der eine hubbegrenzende Funktion ausübt.9 and 10 show the details of the bed unlocking handle 3. A release button 4 protruding at the upper end thereof is connected via a push rod 47 to two release cones 5 arranged one behind the other and sliding in a guide tube 48 which move to the left against the force of a spring 46 let it move. 10, the bed unlocking handle 3 is in the pushed-in position which secures the swivel mechanisms. Here, a locking nose 7 of a locking bar 6, which plunges through a pipe slot 30, bears against the flank of the right cone 5, the pressure at the lower end of the locking bar 6, which rotates about a pivot point 49, being generated by a spring 9. If the bed release handle 3 is pulled out while pressing the release button 4 at the same time, the position shown in FIG. 9 is assumed, and when it is pulled out, the driver 39 at the left end of the lower part of the bed release handle 3 becomes the upper end of the gas pressure spring 33 (Fig. 2) with the roller lever 15 (Fig. 2) connected linkage 11, which has the unlocking of the pivot mechanism for the upper and lower beds 2 and 1 in consequence. The bed unlocking handle 3 cannot be pulled out without pressing the release button 4, because this prevents the locking lug 7 which then lies against the rear of the left cone 5 when the button is pulled. 9, the bed release handle 3 is on the powerless slipping in prevented by a pawl 8 pressed by a pawl spring 31 on the left cone 5, that is to say the bed unlocking handle 3 must also be pushed in while simultaneously pressing the release button 4. With 32 a stop pin is designated, which exerts a stroke-limiting function.

An Hand der verschiedenen Stellungen der Betten 1 und 2 die mit der erfindungsgemässen Einrichtung möglich sind wird in der Folge die Schwenkmechanik näher erläutert.On the basis of the different positions of the beds 1 and 2 which are possible with the device according to the invention, the pivot mechanism is explained in more detail below.

Die vorhergehend beschriebenen technischen Funktionen muss ein Benutzer eines Klappbettes 1 oder/und eines Klapp-Schwenkbettes 2 nicht bewusst ausführen. Die praktische Anwendung ist insofern einfach, als der Benutzer bloss den Bettenentriegelungsgriff 3 herauszieht, die Betten 1 und 2 von Hand in die gewünschte Lage bringt und dann den Bettenentriegelungsgriff 3, zwecks Arretierung der Betten 1 und 2, wieder hineinstösst. Die beschriebene und in den Zeichnungen dargestellte Schwenkmechanik für beide Betten 1 und 2 befindet sich, für den Benutzer unsichtbar, in der Nischenseitenwand 41. In einem Doppelstockwagen 20 ist die beschriebene Einrichtung in gleicher Weise je im oberen und im unteren Geschoss vorhanden und funktioniert auch entsprechend gleich in der Handhabung. Anstelle der verwendeten Gasdruckfedern können auch andere Federsysteme eingesetzt werden wie beispielsweise Spiralfedern, Gummifedern, Torsionsfedern, Kunststoffedern oder Reibungselemente. Die mechanische Übertragung von der Schwenkmechanik des oberen Schwenk-Klappbettes 2 zum unteren Schwenkbett 1 in der Form des beschriebenen Zug-/Druckkabels 19 kann in einer weiteren Ausführung auch durch ein Gestänge, durch eine Hydraulikverbindung oder durch einen doppelten Kabelzug ersetzt werden. Die beschriebene Einrichtung kann in beliebigen Räumen mit engen Platzverhältnissen eingesetzt werden.A user of a folding bed 1 and / or a folding swivel bed 2 does not have to consciously carry out the technical functions described above. The practical application is simple insofar as the user merely pulls out the bed release handle 3, brings the beds 1 and 2 into the desired position by hand and then pushes the bed release handle 3 back in to lock the beds 1 and 2. The pivoting mechanism described and shown in the drawings for both beds 1 and 2 is, invisible to the user, in the niche side wall 41. In a double-deck carriage 20, the device described is present in the same way in the upper and lower floors and also functions accordingly easy to use. Instead of the gas pressure springs used, other spring systems can also be used, such as spiral springs, Rubber springs, torsion springs, plastic springs or friction elements. The mechanical transmission from the swivel mechanism of the upper swivel folding bed 2 to the lower swivel bed 1 in the form of the pull / push cable 19 described can also be replaced in a further embodiment by a linkage, by a hydraulic connection or by a double cable pull. The device described can be used in any room with limited space.
