4 Claims.

This invention relates to mechanism for operating and locking a swinging panel such as a window panel for closing the whole or part of a window opening. Reference is made particularly to swinging panels for automotive vehicles. Swinging panels are used in combination with a vertically adjustable window panel in the forwardmost side opening of a closed body and are also used considerably for the rear quarter windows for automobiles.

It has been found that swinging panels are subject to being forced or pried open, or partially open, so that access can be obtained to a locked vehicle. That is, of course, objectionable since unauthorized persons may obtain access to the car. It is an object of the present invention to provide improved mechanism for regulating and locking swinging panels wherein both operations are performed by a single regulator handle. More particularly, the invention is directed toward the provision of a structure wherein the regulator handle may continue its operating movement subsequent to the closing of the panel, and during this continued movement the locking mechanism is actuated to lock the panel in closed position. Although the regulator handle may be operated subsequent to the closing of the panel the arrangement is such that the panel is positively held closed during this additional movement of the regulator handle, and while the locking member is being shifted to locking position, which position may be that of an engagement with the panel itself or part thereof. These objects will be better understood and other objects appreciated as the following detailed disclosure is considered in connection with the accompanying drawings.

In these drawings are shown two forms of devices which exemplify the invention, it being understood that the invention is not limited to these forms.

First referring to Fig. 1, the body of a car is illustrated at I having a window opening with a swinging panel 2 in its forward portion, and a vertically adjustable panel 3 to the rear of the swinging panel. The control and locking mechanism has to do with the control and locking of the swinging panel.

This swinging panel swings on an upwardly and downwardly extending axis, there being an axis member illustrated at 4 and another axis member illustrated at 5 (Fig. 6). The axis member 5 extends through a channel 6 which extends around the edge of the panel 2. A weatherstrip is illustrated at I having an edge 8 against which the panel is arranged to seal when in closed position. By making reference to Fig. 6, the general environment will be seen, wherein the outer panel of the vehicle is illustrated at 9, the garnish molding around the window opening illustrated at Ill and an inner panel for the body shown at II.

There is a back plate l5 which forms a support for the regulator mechanism, and it'is arranged to be secured to a suitable supporting member such as an inner metal panel IS. A box member I! is secured to this back plate, as for example by rivets as shown in Fig. 7, and this box has portions [8 for the reception of caps l9 for the journaling of a crank member 20 having a crank 25, the crank member being secured to the axis member 5 as illustrated at 22. The control handle is illustrated at 25 and it is arranged to operate a screw threaded spindle 26 journaled in' the back plate at 2'! and in the box or housing as at 28. A nut 30 is mounted upon the screw threaded spindle to be fed thereon, and it is formed with a slot 31 defined on one side by a relatively long projection 32 having an inclined surface 33, and defined on its other side by a relatively short projection 34 with a relatively flat surface 35. The slot 3| is designed to engage the throw of the crank.

The nut has a stud 33 which is arranged to operate the locking mechanism. This locking mechanism comprises a lever pivoted to the housing as at 4! and having a recess 42 defined on one side by a relatively long finger 43 and on the other side by a lower abutment or wall 44. The stud 33 operates in a slot 45 of the housing and it is arranged to rock the lever 4| by engaging the finger 43 and abutment 44, and it is also arranged to be accommodated by the notch 42. A link is pivoted to the lever 40 (Fig. 5), and at its opposite end is pivoted as at 5| to a rocker arm 52, in turn pivotally mounted on the housing as at 53 (Fig. 3) A locking bar is illustrated at 54 having a connection with the housing which takes the form of a slot 55 in the locking bar, which receives a stud 56 on the housing. The locking bar has a slot 5'! which receives a pin 58 on the rocker arm 52. The locking bar has a locking portion 59 arranged to extend through openings in the back plate and through the sealing strip and associated metal part or parts, as shown in Fig. '7, the openings in all of these elements being generally shown at 60. The channel 6 around the edge of the panel is fashioned with an opening 55 which constitutes a keeper for the locking portion of the locking member.

This structure constitutes one form of device for carrying out the invention, and its operation might best be considered before proceeding with the other form. When the crank is turned the nut is fed one way or the other on the screw threaded shaft. When the throw of the crank is engaged in the notch 31 it will be appreciated that the crank is rocked, resulting in swinging movement of the panel. The open position of the parts is illustrated in Fig. 5, this illustrating substantially maximum open position. Now as the handle is rotated to feed the nut upwardly (as Fig. 5 is viewed) the crank is turned and the window is closed. When the window is completely closed no further motion is imparted thereto, but the crank may be further operated to actuate the locking mechanism. Fig. 4 shows how the nut has moved upwardly (as Fig. 4 is viewed), and

the throw of the crank is actually moved out of the notch. When the throw of the crank is so positioned that it engages the flat surface 35, the window is closed and the nut may be fed further upwardly (as indicated in Fig. 4) without rotating the crank, the crank merely resting upon the surface 35 and serving to hold the panel tightly closed. In this final movement, while the throw of the crank is sliding along the surface 35, stud 38 engages the finger 43 and rocks the lever 40 from the position shown in Fig. 5 to the position shown in Fig. 4. This, through the link 50, rocks the arm 52 and the pin and slot connections iii-53, causes the lock member 54 to be projected upwardly (as Figs. 2 and 3 are viewed) until its end is projected into the keeper 6| as shown in Fig. '7. It will be understood that the locking member 5 is slidably guided at each end, one end being on the stud 56 and the other in the openings 65.

The panel is now closed and locked. To open the panel the handle is turned in the opposite direction. In this initial movement the surface 35 slides along under the throw of the crank so that no swinging movement is imparted to the window; at this time the stud 33 engages the shoulder 44 and rocks the lever 40 from the position shown in Fig. 4; to the position shown in Fig. 5. This retracts the locking member and disengages it from the keeper 6|. At this time the throw of the crank is engaged by the surface 33 and thereafter the throw of the crank is engaged in the notch 3| and the window panel may be swung and adjusted as desired.

In the modified form shown in Figs. 9 to 14 I inclusive, many of the parts have the same general characteristics, and in order to avoid unnecessary duplication in description the same reference characters are applied. Such parts include the window panel and the parts directly associated therewith, such as its axis member, the back plate, the threaded spindle, the traveling nut and the crank and its mounting.

The locking member 55a slides in the aperture 69, is offset as at It] and has a slotted portion H operating on a stud 12. A slide 13 has an aperture M in an inclined portion in which is received a stud '15 carried by the loclnng member. This aperture has its upper end portion positioned substantially perpendicular relative to the sliding look, as illustrated at '36. A bracket I1 is secured to the back plate and carries a stud 18 positioned in an aperture !9 of the slide member. This slide member has an aperture 83 in one end and it is pivotally connected at Ma. with a lever ii -a substantially corresponding to lever 50 of the previously described form and having the same projection or notch arrangement indicated by the characters 43a, 44a and 42a.

In this form, the reciprocation of the nut rocks the crank to swing the window panel and when the nut is near one end of its movement the throw of the crank rides on the surface 35. As the nut moves, the stud 36 swings the lever 30a and thus shifts the slide member 73. When the slide member is shifted to the right as shown in full lines in Fig. 9, the stud l5 rides up the inclined slot 14 and lifts the locking bar into locking position in the keeper 6!. At the end of this movement stud l5 lies in the end 76 of the slot so that the locking member is held strongly in looking position. As the slide member 13 moves toward the dotted line position shown in Fig, 9, which movement takes place when the handle is rotated in the direction designed to swing the window open, the pin 15 is caused to slide downwardly in the inclined slot 74 and the locking member 54a is moved to unlocking position. These movements of the slide 73 occur while the throw of the crank is riding on the surface 35 of the nut as previously described.
