OPENING AND SHUTTING MECHANISM FOR A WINDOW

Abstract

The present invention refers to a mechanism for the opening and for the shutting of a window, particularly designed for use in the emergency windows of a public transportation vehicle provided with a lower release and locking window (1) system and another upper system that allows for the scaling when opening it, considering the fact that the lower system is actuated by means of a lever (5) that extends along the lower extremity of the window (1), which allows for its actuation by any passenger positioned in its proximity.

DETAILED DESCRIPTION OF THE INVENTION

The present invention refers to a window opening and shutting mechanism placed on the lower part of the window (1) in the inner side of the vehicle (not illustrated), as it is better illustrated by the FIGS. 1, 4, 5, 6 and 8. The mechanism comprises of a tripod (4) (FIG. 4) fixed to a lower profile (7) which frames the lower portion of the opening for the window (1); a longitudinal lever (5) fixed to the lower extremity of the window's glass (11) by means of a fixture (2) that allows for the rotation in relation to the window (1) between the positions of locked and unlocked; a palette or a lock (6) that has one of its extremities (62) pressed against the upper portion (41) of the tripod (4) when the mechanism is locked, and its opposing extremity (61) is articulate with the lever (5) in such a manner that when the window (1) is closed and the lever (5) is turned towards the bottom, the palette or lock (6) is kept under pressure against the tripod (4) pulling the window (1) against the bodywork of the vehicle and thus locking it (FIG. 4).

The palette or lock (6) remains stable when the lever (5) is facing downwards, and preferably forming an angle (a) with the vertical line between 0° and 90°.

The means of fixation (2) of the lever (5) on the window (1) can be any, provided it permits the rotation of the lever (5) in relation to the window (1), for instance, a pin, an axle, a hinge, etc.

In order to unlock the mechanism one pushes the edge (51) of the lever (5) in an upward direction, which by its turn carries the palette or lock (6) along with it, rotating it around its extremity (52) releasing it from the tripod (4). At this very moment the window (1) is free and is released to be pushed towards the outside, taking with it the lever (5) and the palette or lock (6).

If the intention is not to open the window (1), in order to lock it against the vehicle's bodywork once again, all the user has to do is to push the lever (5) downwards, it in turn will push the palette or lock back to its initial locking position, that is to say, locked in relation to the tripod (4), thus keeping the window (1) closed.

The window (1) is supported by the vehicle's bodywork by its upper edge, by means of the co-operable fitting of a profile (8) of the window (1) in one profile (9) of the bodywork, both of them in the shape of a hook that thus allows for the window (1) to rotate around the fitting when unlocked. The fitting is made between a longitudinal profile fixed to the upper extremity of the glass (11) of the window (1) provided with an edge (82) in the shape of a hook along its length; and a profile (10) which frames the upper portion of the bodywork's opening to the window (1) provided with a hook (9) where the edge (82) is fitted keeping the window (1) in a hanging position. The hook (9) can be of a separately manufactured profile from the profile (10) and can be fixed to it afterwards.

The profile (8) comprises of a central widened portion (81) that functions like a window post for the window (1) limiting its opening.

As it is illustrated by the annexed figures the window (1) comprises of elastomeric profiles (gaskets) (3 and 12) that extend along the edge of the glass (11), which prevents against the water entering the interior of the vehicle (not illustrated) and the finishing profiles (13, 14 and 15) of the finishing touches of the window (1).

FIG. 9 presents a perspective view of the lever (5) turned upwards and the palette or lock (6) supported on the tripod (4) before the window (1) is opened. To facilitate the visualization of the present mechanism, this figure does not present the finishing frames (13 and 14) of the bodywork openings and the gaskets (3 and 12) of the window (1).

The window may comprise of one or more tripods (4) and palette or lock (6) associated with the lever (5), preferably two tripods (4) and corresponding palettes or locks (6) as it is illustrated in the FIGS. 1 and 5, which thus offer a better closing for the window (1).

The artisan with ordinary skills in the art will promptly perceive from the exposed description, as well as from the figures and drawings hereby shown, that there are a variety of manners to realize the invention without departing from the scope of the annexed claims.

Claims

1. A mechanism for the opening and shutting of a window which comprises the following features: a tripod (4) fixed to a lower profile (7) that frames the opening for the window (1); a longitudinal lever (5) fixed to the lower extremity of the glass (11) of the window (1) by means of a fixture that allows for its rotation in relation to the window (1); a palette or a lock (6) which has one of its extremities (62) pressed against the upper portion (41) of the tripod (4) when the mechanism is locked, and its opposing extremity (61) is articulate with the lever (5) in such a manner that when the window (1) is closed and the lever is facing downwards, the palette or lock (6) is kept under pressure against the tripod (4).

2. A mechanism for the opening and shutting of a window according to the claim number 1 which has the feature that when the mechanism is locked the palette or lock (6) forms an angle (α) with the vertical line between 0° and 90°.
