Abstract

The trolley runs on four castors, each provided with an automatic brake. When an operating lever (4) on the end wall (3) of the trolley is pushed down, eccentric bolts are turned by a pair of connecting rods (7a 7b) in the trolley side. The bolts raise spring-loaded pegs on whose lower end are fitted brake discs, thus releasing the castors. When the operating lever is freed, the brakes are automatically re-applied by the springs on the brake pegs. This ensures that the trolley cannot move, when not required, while brakes on all four wheels ensure that wear and tear on the aircraft floor is minimised.

Description

Fahrbarer Behälter Mobile container

Die Erfindung betrifft einen fahrbaren Behälter, insbesondere einen Servierwagen zum Einsatz in Verkehrsmitteln.The invention relates to a mobile container, in particular one Serving trolley for use in transport.

In Verkehrsmitteln ist es aus Sicherheitsgründen notwendig, daß ein Servierwagen in jeder Lage und zu jeder Zeit zum Halten gebracht werden kann. Insbesondere in Flugzeugen werden hohe Anforderungen an die Betreibssicherheit gestellt. Man hat zum sicheren Anhalten eines beladenen Servierwagens bereits einen schwenkbaren Bremsfuß vorgeschlagen, welcher von beiden Stirnseiten des Servierwagens aus über entsprechende Gestänge betätigt wird (DE-PS 22 62 837). Der mit dem Fußboden in Bremsberührung kommende Bremsfuß führt aber ts Laufe der Zeit zu unerwünschtem Verschleiß des Fußbodens.In transport it is necessary for safety reasons that a Serving trolley can be brought to a stop in any position and at any time. In particular In aircraft, high demands are placed on operational safety. Man Already has a swiveling trolley to safely stop a loaded serving trolley Brake foot proposed, which from both ends of the serving trolley over corresponding linkage is operated (DE-PS 22 62 837). The one with the floor in Brake foot coming into contact with the brake, however, leads to undesirable wear over time of the floor.

Der Erfindung liegt die Aufgabe zugrunde, bei nichtbetätigtem Servierwagen automatisch eine Bremsung bei gleichzeitig festem Stand des Wagens zu gewährleisten, ohne daß der Fußboden in Mitleidenschaft gezogen wird. Die erfindungsgemäße Lösung einer derartigen "Deadman-Bremse" erfolgt mit dem im Kennzeichen des Patentanspruches angegebenen Merkmalen.The invention is based on the object when the serving trolley is not actuated to ensure automatic braking while the car is stationary at the same time, without affecting the floor. The solution according to the invention such a "deadman brake" takes place with the characterizing part of the patent claim specified features.

Auf diese Weise wird ein Servierwagen grundsätzlich in Ruhestellung, d. h. ohne daß etwas betätigt wird,an zellen vier Rollen gebremst. Durch Betätigen eines der beiden stirnseitig oben angeordneten Bedienungshebel werden alle vier Rollen gleichzeitig gelöst. Dabei entfällt eine besondere Verschleißbelastung des Fußbodens.In this way, a serving trolley is always in the rest position, d. H. without anything being actuated, four rollers are braked on cells. By pressing one of the two control levers arranged at the top, all four Roles solved at the same time. There is no particular wear and tear on the Floor.

In der Zeichnung ist ein Ausführungsbeispiel der erfindungsgemäßen einfachen aber wirkungsvollen Vorrichtung dargestellt.In the drawing is an embodiment of the invention simple but effective device shown.

Es zeigen: Fig. 1 einen Servierwagen in perspektivischer Sicht Fig. 2 eine Seitenansicht mit dem einglassenen Doppelgestänge eines Bedienungshebels in Seitenansicht gemäß Pfeil II.(gebremst) Fig. 3 Das Gegenstück zu Fig. 2 gemäß Seitenansicht Pfeil III (ungebremst) Fig. 4a Einen Schnitt durch den Bedienungshebel mit dem + 4b Anschluß an das Doppelgestänge Fig. 5a ein n Schnitt durch den Bereich der Exzenterwellen + 5b und Fig. 6a einen Schnitt durch den Bereich der Rollen jeweils + 6b in Betriebs- und Ruhestellung.They show: FIG. 1 a serving trolley in a perspective view. 2 a side view with the embedded double linkage of an operating lever in side view according to arrow II. (braked) FIG. 3 The counterpart to FIG Side view arrow III (unbraked) Fig. 4a A section through the operating lever with the + 4b connection to the double linkage Fig. 5a an n section through the area of the eccentric shafts + 5b and FIG. 6a shows a section through the area of the rollers, respectively + 6b in operating and rest position.

Der als Servierwagen ausgebildete fahrbare Behälter 1 besitzt an seiner Unterseite vier Rollenpaare 2 und an seinen beiden Stirnseiten 3 je einen Bedienungshbel 4. Sowohl im Bereich der hinteren beiden Rollenpaare als auch der vorderen beiden Rollenpaare ist im Geräteboden 5 je eine Exzenterwelle 6 angeordnet, Von jedem der beiden Bedienungshebel 4 führt eine Doppelgestänge 7 zu den Exzenterwellen 6 und zwar jeweils ne Stange 7a zu der vorderen und die andere Stange 7b zu der hinteren Exzenterwelle. Während das Doppelgestänge des einen der beiden Bedienungshebel in die linke Seitenwand 8a eingelassen ist, führt das Gegenstück durch die gegenüberliegende Seitenwand 8b. Beim Herunterdrücken eines der beiden Bedienungshebel4 werden über das dazugehörige Doppelgestänge 7 die im Geräteboden 5 angeordneten Exzenterwellen 6 verdreht.The mobile container 1 designed as a serving trolley has on his Underside four pairs of rollers 2 and one operating lever on each of its two end faces 3 4. Both in the area of the two rear roller pairs as well as the front two Pairs of rollers is arranged in the device base 5 each an eccentric shaft 6, of each of the two operating levers 4, a double linkage 7 leads to the eccentric shafts 6 and in each case ne rod 7a to the front and the other rod 7b to the rear Eccentric shaft. While the double linkage of one of the two control levers in the left side wall 8a is let in, the counterpart leads through the opposite one Side wall 8b. When one of the two operating levers4 is pressed down, over the associated double linkage 7 the eccentric shafts arranged in the device base 5 6 twisted.

Dabei gleiten federbelastete Bolzen 9 nach oben, so daß die unten an den Bolzen 9 angebrachten Bremsscheiben 10 von den Rollen 2 abheben. Der Servierwagen kann verfahren werden, solange der Bedienungshebel in Bedienungsstellung gehalten wird. Sobald dieser aber losgelassen wird, bewirkt ein Federdruck den umgekehrten Vorgang und alle Rollen werden automatisch gebremst. In den Fig. 4a bis 6b ist der Vorgang veranschaulicht.Spring-loaded bolts 9 slide upwards so that the bottom Lift the brake disks 10 attached to the bolts 9 off the rollers 2. The serving trolley can be moved as long as the operating lever is held in the operating position will. As soon as this is released, however, spring pressure does the opposite The process and all roles are automatically braked. 4a to 6b is the Process illustrated.

Sobald einer der Bedienungshebel 4 durch das Beeienungspersonal losgelassen wird, werden mittels Federdruck die beiden Stangen des Doppelgestänges 7 ifl die untere Stellung gemäß Fig /la bewegt. Die Exzenterwelle 6 nimmt dadurch die Stellung gemäß Fig. re en und hewegt den Bolzen 9 mit der Bremsscheibe 10 in die Bremsstellung gemäß Fig. 6a. Wird der Bedienungshebel L dagegen nach unten gedrückt, dann erfolgt die in Fig. 4bt Sb und 6b gezeigte ungebremste Stellung und zwar auf allen vier Rollen, unabhängig davon, welcher der beiden Redienungshebel betätigt wird.As soon as one of the operating levers 4 is released by the operating personnel the two rods of the double rod 7 ifl die moved lower position according to Fig / la. The eccentric shaft 6 takes the position according to Fig. Re en and moves the bolt 9 with the brake disc 10 in the braking position according to Fig. 6a. If, on the other hand, the operating lever L is pressed down, then takes place the unbraked position shown in Fig. 4bt Sb and 6b on all four Roles, regardless of which of the two control levers is operated.
