BRIEF SUMMARY
BACKGROUNG OF THE INVENTION
The present invention relates to a passenger passageway between rail vehicles or railway cars and consisting of two extractable and retractable half-passageways arranged at the ends of the cars to be coupled with each other. The half-passageways have centering and locking devices on their directly opposite main frames. The locking device consist of locking hooks which are arranged on a vertical support of each half-passageway and they are connected for movement with each other, consist of corresponding receivers on the opposite vertical support, and consist of an actuating device for the locking hooks.
Passenger passageways of this type operate today without the previously customary positive guidance of the passageway but rather with a free equilibrium guidance of the diaphragm which is limited by stops. The passageways thereby have a shorter installation length on smooth end walls with stable bridging and support structures and locks. These passageways furthermore have vandalism-proof inner sheathing.
The object of the present invention is to provide, in passenger passageway of the type described above, on the one hand a locking device which is simple to operate and, on the other hand, a device, also of a simple nature, for the pulling of the half-passageways together against the restoring forces of diaphragms and possibly of restoring springs. These devices are to be arranged on the passageway itself, to take up the smallest amount of space but to optimally function.
This object is achieved in accordance with the invention. The passenger connecting passageway between two rail vehicles includes a respective half-passageway at the end of each vehicle. Each half-passageway has a respective main frame. To lock the half-passageways together, a locking device including at least one locking element, in the form of a hook and preferably a pair of hooks is arranged on the outside of one vertical support of the main frame of one half-passageway. A receiving pin on the adjacent main frame of the other half-passageway receives the hook. A device swings the hook selectively on and off the pin. half-passageway including a pull strap supported at the vertical support on one half-passageway that hooks on a receiver on the vertical support on the other half-passageway. A ratchet rotates an arm that winds the strap to pull the half-passageways together.
The present invention makes it possible, in a very simple manner, to lock the half-passageways of coupled cars to each other and to pull the half-passageways together into the position required for the locking. Other features of the invention are explained in somewhat more detail below on the basis of embodiments shown in the drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is an exploded sketch of a half-passageway (the half-passageways being identical to each other);
FIGS. 2 and 3 show, diagrammatically two half-passageways in locked and unlocked condition respectively;
FIGS. 4 and 5 show, diagrammatically two passageway halves before they are pulled together by the tensioning device;
FIGS. 6 to 9 show, diagrammatically the mechanism of the locking device; and
FIG. 10 shows the mechanism of the pulling-together device for two half-passageways.
DESCRIPTION OF THE PREFERRED EMBODIMENT
A complete passenger passageway between two rail vehicles consists of two entirely identical half-passageways. Due to their arrangement with mirror-symmetry contact elements, cars equipped with this type of passageway can be freely coupled. This means that upon the coupling of the cars, each car end fits any other car end.
As shown in FIG. 1, each half-passageway consists of a main frame 1 with centering elements. The frame 1 is being attached in dust-tight and water-tight manner to a one-piece flexible diaphragm 2 by means of clamping ledges 3 on a mounting frame 4. The mounting frame 4 is bolted to the body of the car. Between the mounting frame 4 and the body of the car there is a packing 5, and on the coupling surface of the main frame 1 there is a pac
