Description

The present invention relates to a device for locking a pivoting window in closed or ajar positions, in particular, a pivoting window of the rear quarter of a motor vehicle.

In the prior art, pivoting window locking devices are known comprising, in general, two articulated rods, disposed opposite the pivot axis of the window. Among the disadvantages of such devices, we can cite the lack of tightness they give to the glass due to a loss of crushing of the seal after misalignment of the articulation points of the rods necessary for locking of the glass.

Furthermore, the trajectory of the control rod during maneuvering protrudes into the passenger compartment of the vehicle, leading to risks of aggressiveness in the event that the opening of the window is only made halfway through its travel.

A solution to the previous technical problems has already been described in French patent application No. 78.31.210, filed by the present applicant.

This device comprises an articulated connecting rod, on the one hand, sliding in a lever pivotally mounted on a support and, on the other hand, a yoke mounted with a certain degree of rotation in a base fixed on the glass and a set of cams in contact for locking (unlocking of the lever in the closed or ajar position of the window).

The object of the present invention is to propose a new, simpler and more economical solution to the previous sealing and bulk problems by which the glass seal remains at a constant compression level during the worm maneuver. - rusting / unlocking.

The structure of the lock, according to the invention, involves a minimum of movable parts which can be fitted into each other to reduce the overall size of the assembly while their developed trajectories during the window-opening operation does not create any additional projection in the passenger compartment of the vehicle.

The device is essentially characterized in that it comprises: a rod which can be fitted completely inside the body of the bolt mounted on the body and the yoke fixed on the glass, rod moved by a combination of sliding and pivoting movements communicated from of the translation of an operating button, parallel to the body of the lock.

The operation of the button first causes the translation of the connecting rod on two extreme pins sliding in guide buttonholes formed in the body and in the yoke to unlock the connecting rod. Continued operation of the button then causes the window to open up because the pins also serve as pivots for the articulation of the connecting rod, in particular when they come into abutment in their respective buttonholes. The connecting rod therefore constitutes the only moving part of the mechanism.

Figure 1 shows the locking device and interlocking of a pivoting quarter window 1, mounted on the adjacent body 2 defining the framing of the glass by means of a fixing lug 3, extending the body 4 of the lock , set up and held in a stamped 5 of the body by two screws 6.

The lock essentially consists of a hollow body 4, a yoke 7 fixed on the window 1 and a movable connecting rod 8 capable of being completely embedded in the housings formed by the body and the yoke and actuated by a button. operation 9.

All of these parts are preferably made of synthetic material.

The yoke 7 is fixed on the inner face of the window 1 and held against it by means of a screw 10 passing through the window and engaging in an unremovable external nut 11, with a round head, with interposition on the outside face of the glass of a cover 12 provided with a seal.

As seen in Figures 4 and 5, the wings 13, 14 of the yoke are crossed by an oblong buttonhole 15, parallel to the plane of the glass and forming a cross section with the central housing 16 of the yoke to receive and guide two opposite pins 17a, 17b, carried by the opposite faces of one end of the connecting rod 8 which can thus slide in the buttonhole 15 of the yoke and pivot around its pins 17a, 17b.

At its other end, the connecting rod is also movably connected to the body 4 of the lock by means of another pin 19 sliding in an oblong buttonhole 20 of the body and secured to the operating button 9 outside the body.

The hollow body 4 has a U-shaped section, one wing 21 of which is pierced by the buttonhole 20 and is let through by the pin 19 connected to the button.

The buttonhole of the body has an oblique portion 20b oriented towards the yoke, interposed between two end portions 20a, 20c, parallel between them and parallel to the straight buttonhole 15 of the yoke when the window is closed.

Furthermore, the internal wall of the wing 21 of the body comprising the buttonhole has a curvilinear grouser 22 extending towards the inside of the body by a so-called locking groove 23, provided for receiving the corresponding lateral rib 24 formed on the heel. of the connecting rod 8, more visible in FIG. 5.

Thus, as shown in FIG. 2, the connecting rod can be completely embedded inside the body, the heel of the connecting rod matching the external contour 25 of the lock, on the side of the introduction.

The lock body also has two shoulders 26, 27, so as to partially fit the yoke 7 during the closing of the window, which gives the assembly good rigidity and minimal bulk with respect to the plane of the window. , towards the interior of the vehicle cabin, thus limiting the danger of an excessively prominent projection. This result can also be expressed by pointing out that, despite the length of the rod 8 necessary for sufficient opening of the window, the distance of the pins 17, 19 from the window is reduced to a minimum dimension.

Figure 1 being taken from inside the vehicle, we note that the operating button 9 evolves in translation under the body 4 of the lock, therefore without presenting any additional projection towards the interior of the vehicle relative to the wall 28 of the body furthest from the glass (Figure 2). On the contrary, the oblique portion 20b of the buttonhole tends to move it outwards. Furthermore, as in the position of use the buttonhole 20 is located under the body, the mechanism is protected against possible introduction of dust by the buttonhole.

• En partant de la figure 2 qui représente la vitre 1 en positions fermée et verrouillée, l'utilisateur déplace le bouton de manoeuvre 9 vers la droite (figure 3), guidé par la boutonnière 20 du corps de verrou, ce qui libère la nervure de verrouillage 24 de la bielle de la rainure 23 correspondante du corps. Ce mouvement de translation de la bielle 8 est limité par le pion 17 arrivant en butée dans la boutonnière 15 de la chape.

The device works as follows:

• Starting from FIG. 2 which represents the window 1 in the closed and locked positions, the user moves the operating button 9 to the right (FIG. 3), guided by the buttonhole 20 of the body of latch, which releases the locking rib 24 of the connecting rod from the corresponding groove 23 of the body. This translational movement of the connecting rod 8 is limited by the pin 17 arriving in abutment in the buttonhole 15 of the yoke.

From the unlocked position of Figure 3, continuing to operate the button 9, the pins 17a and 17b of the connecting rod rotate in the yoke and become pivots for the articulation of the connecting rod.

In a circular movement, the connecting rod 8 moves the yoke 7 away from the body of the latch 4, causing the glass 1 to open up as shown in FIG. 4.

The maximum gap is reached when the pin 19 secured to the button reaches the bottom of the buttonhole of the body to the bearing 20c allowing the rod to be held in this stable position. Indeed, at the end of the race, the axis of the pin 19 exceeds the perpendicular 25 to the window passing through the axis of the pins 17 pivoting in the yoke.

The closing and locking of the window proceeds from the reverse of the previous operations. The compression of the gasket (not shown) of the glass in the window frame takes place during the actual closing, that is to say during the passage from Figure 4 to Figure 3 The locking, that is to say the transition to FIG. 2, therefore takes place at maximum and constant compression since the positions of the body and of the yoke remain fixed, only the connecting rod 8 being moved parallel to the plane of the glass. .

During closing, the rib 24 of the connecting rod comes into contact with the ramp 22 of the body while the yoke comes to fit between the abovementioned shoulders 26, 27 of the body. Then the translation of the pins 17, 19 in their respective buttonholes causes a positive locking by the engagement of the lateral rib 24 of the connecting rod in the groove 23 of the body.
