ETABLISSEMENTS GEORGES KLEIN

Window opening with hinged window.

The invention relates to a window opening with a hinged window, i.e. a window opening, in particular for Railway vehicles or road vehicles (or also for buildings), which has a pivotable glazed frame or a pivotable pane, i.e. which around a particular horizontal axis can be swiveled

It has long been envisaged to provide these window openings with stop means, in particular Spring-loaded fingers or the like. To hold the pivotable part in any of various working positions. These agents are generally quite involved and inconvenient.

To simplify this stop means, according to the invention, they are provided by an arrangement with at least a spring leaf and a limb, e.g. a finger, a

Roller or a pen, formed, which is in the movements of the pivotable part against the spring leaf, the spring e.g. from the fixed part of the window opening and the mentioned, te Member is carried by the pivoting part

The spring can in particular be approximately C-shaped and at least one of an intermediate position of the opening of the window opening have a corresponding rest

The invention is explained below by way of example with reference to the drawing.

As shown, the spring 3 is in particular *. supported by a small housing or cover 6 on the fixed frame 7 of the same is attached to the side attached to the window opening and, for example releasably]!. '

Such a housing 6, which is preferably provided on either side of the window opening, has e.g. a triangular plank, which ends laterally in edge strips 8, 9, and an edge 11, with which the pivotable part 2 comes into contact in the position of full opening

The spring 3 is for example attached to the upper part of the housing, in particular under the upper edge strip 9

If, with such an arrangement, the rollers 4 are provided at a suitable height opposite the spring 3, which in turn has a suitable length, obviously serves · the spring as an end stop both for the closed position I. (fully extended in Fig. 2), as well as for position II of the complete Opening (dash-dotted line in Fig. 2). For the transition from one to the other of these two positions, each roller 4 must compress the C-shaped spring 3 slightly. ! However, as shown, the spring can do little-:

at least contain a detent 10, which the roller 4 for an intermediate position III receives, which is thus stabilized by the reaction of the spring on the roller in the detent. j Of course, another solution can also be chosen. In particular, the spring 3 can have a different gate i

and form part of the housing. ;
