Karl Bell Attorney-Beaman and Beaman [57] ABSTRACT A window regulator for sequentially operating two, substantially coplanar, separate, window panels slidably mounted within an automobile door, one of the window panels constituting a small vent, and the other window panel constituting a primary side window. Single operating means for both window panels, which is either manual or motorized, actuates the regulator mechanism through two consecutive stages of operation whereby movement of the regulator in a single direction first fully operates one window panel through its full range of adjustment, and upon such panel adjustment being completed, then operates the other panel through its adjustment range. The regulator includes a gear segment and a lever pivotally associated with each window panel. Lost motion means interconnecting the gear segment and the levers produces the sequential window regulation, and locking means are utilized with the levers to lock the window panels in desired terminal conditions.

sum u [1F 4 INVENTOR MAX 0. HEESCH ATTORNEY MULTIPLE STAGE WINDOW REGULATOR BACKGROUND OF THE INVENTION The invention pertains to a multiple stage automobile window regulator using common operating structure to regulate two window, panels.

In the design of automobile ventilation systems it is known to incorporate small vent windows into the vehicle window system whereby improved air circulation and venting may be readily achieved. Usually, the vent window is located at the forward portion of the window spaceof the automobile front door, and the most common window vent construction mounts the vent window upon a substantially vertical pivot axis such that the vent window may be pivoted between opened and closed positions.

The operation of vent windows mayinclude a direct manipulation of the window wherein a handle, often a pivotal locking handle, directly mounted upon the vent window frame is grasped to position the vent. A more expensive construction entails the use of vent window regulators incorporated into the vehicle door employing a gearing system whereby a manually operated crank rotatably mounted upon the door interior is employed to pivot the vent window. In more expensive automobiles vent window operation may be motorized and controlled by an electric switch.

For purposes of convenience, economy, space conservation, and other factors, it has been proposed to operate both the vent window, and the larger primary window panel located in the same door as the vent, from a common crank handle rotatably mounted upon the door interior. In such arrangements the windows operate in stages or sequence, and devices of this type are shown in US. Pat. Nos. 2,152,055; 2,448,796 and 2,955,817.

When controlling the regulation of two window panels from a common regulator various problems are encountered which are not present with the more conventional single window panel regulator operation. For instance, in an arrangement whereby a regulator controls a single window panel, lockingof the window in the closed position is achieved merely by cranking the window regulator to the full up condition. If the window panel vibrates downward slightly, the desired fully closed condition can be reachieved by crank handle operation. However, in a multiple stage regulator where sequential operation between stages is produced, the locking of one window panel in a closed condition may not be directly achieved by the operator if such window to be locked is raised prior to the raising of the second window panel due to the sequential operation of the regulator. Thus, the operation of two window panels from a common window regulator requires locking and constructional feature uniquely adapted to operational characteristics, and as existing multiple stage window regulator do not comply with present safety and operating requirements the regulator in accord with the invention has been developed to comply with present automobile standards.

SUMMARY OF THE INVENTION It is an object of this invention to provide a multiple stage window regulator capable of operating two vertically' slidable window panels from a single manually operated crank, or motor.

In the practice of the invention a relatively small vertically slidable vent window is mounted adjacent a large primary vehicle window panel which is slidablein a plane generally coincident with the plane of operation of the vent window. It is desired to regulate both the vent window panel and the primary window panel by the same regulator, which may be either manually operated through a conventional crank, or maybe motor operated. When both window panels are in the up or closed position, operation of the regulator in the down direction first fully lowers the bent window, and then lowers the main window panel only after the vent has been completely retracted to its lowermost position. Reversal of the direction of movement of the regulator apparatus raises the main window panel to the fully closed position, and locks the main panel in such closed position prior to raising the vent window from its fully lowered position. Means are also provided for locking the vent window in the fully lowered position during regulation of the main window panel, and lost motion means are employed to insure the proper sequence of operation.

The invention employs a gear segment or sector pivotal about an axis of rotation. A manually rotated crank pinion, or motor driven pinion, meshes with the teeth of the gear sector whereby the gear sector may be rotated in either direction of movement by the manual rotation of the pinion, or by the motorized driving thereof. A first lever pivotally mounted upon the gear sector axis has an outer end connected to the vent window panel by a conventional track and follower device. A second lever, also pivoted to the gear sector axis, includes an outer end connected to the primary window panel through a track and follower. Lost motion means are interposed between the first lever and the'gear sector for selectively establishing connection between the first lever and the gear sector during movement of the gear sector in either direction during a predetermined arc of movement of the sector. Likewise, additional lost motion means are interposed between the second lever connected to the main window panel and the gear sector producing operation of the second lever through movement of the gear sector in either direction through a second arc of movement.

In order that the primary window panel may be locked in its full up or closed position, even though the vent window may be partially open, a fixed detent is employed as locking structure which cooperates with a pivoted locking latch mounted upon the primary window panel lever which insures that the desired closing pressure for the primary window panel is achieved at all times. 3

When the vent window is fully retracted it is desired that the vent panel not inadvertently lift under shock or impact, until raised by the regulator, and locking means are also interposed between the gear sector and vent lever mechanism to prevent raising of the vent window until allowed by the regulator.

The lost motion structure interposed between the vent lever and the gear sector includes a third pivotally mounted lever having an abutment receivable within a notch defined on the gear sector during pivoting of the gear sector through its first arc of movement. In this manner the notch and the third lever, which is linked to the vent lever, establishes a mechanical drive interconnection between the vent lever and the gear sector during sector movement through its first arc. The lost motion connection between the primary window lever and the gear sector is incorporated into the locking latch mounted upon this lever, and such structure includes a cam slot defined in the latch receiving a cam follower mounted upon the gear sector. The configuration of the cam slot is such that the latch is pivoted free from engagement with the locking detent during the initial movement of the gear sector through its second arc of movement during window retraction.

The operation of the lost motion means is automatically achieved, and the locking of the window panels at their selected terminal positions is likewise automatically accomplished without attention on the part of the operator. The desired window movement and regulation is produced merely by rotation of the window crank in the desired direction, or actuation of the drive motor, and no special skills are required to produce the desired sequence of operation, and locking of the window panels.

It is therefore an object of the invention to provide a multiple stage window regulator capable of regulating the position of two window panels through a common actuator wherein sequential window panel raising and lowering may be achieved, and locking of the window panels at selected positlons is automatically achieved.

DESCRIPTION OF THE PREFERRED EMBODIMENT In FIG. 1 the window regulator 10 in accord with the invention is illustrated as associated in the front door of an automobile schematically represented at 12. The window structure is only generally disclosed as it forms no specific part of the invention, and includes a small vent window panel 14, and a primary larger window panel 16. The window panels 14 and 16 are located in substantially the same general plane, and are movable in a vertical direction between the full up positions illustrated in FIG. 1, to fully retracted positions within the confines of the door 12 wherein the upper edge of the window will be disposed below the door sill as indicated at 18. The window panels are guided for movement within conventional vertically disposed guides or tracks, not illustrated, and the vent window panel 14 includes a conventional track 20 of the known U- shaped transverse cross-sectional configuration for receiving the roller or follower mounted upon the window regulator lever. The primary window panel 16 also includes a like track 22 for receiving its associated window regulator lever, and the path of movement and the lower positions of the panel tracks 20 and 22 are illustrated in dotted lines in FIG. 1. When the window pane] tracks are in the lower dotted line positions the associated window panel is in the fully open or retracted position.

The window regulator 10 in accord with the invention is mounted upon an internal metal panel 24 located within the vehicle door 12 below the sill 18 as is well known in automobile door construction. The regulator apparatus includes a base plate 26 attached to the door inner panel by screws or bolts, not shown, and the base plate includes a pinion gear housing 28 for rotatably supporting a pinion gear 30, FIG. 5, in suitable bearings. The pinion gear 30 may be rotated by a crank mounted upon the door interior side, in the well known manner, or the pinion gear may be connected to reversible electric motor dive means in those embodiments wherein window operation is to be motorized.

The base plate 26 includes a pivot axis shaft 32 extending from the base plate toward the viewer, FIG. 1. The regulator structure further includes a gear sector 34 rotatably mounted on the pivot shaft 32. The gear sector includes a circumferential portion concentric to the pivot shaft 32 upon which gear teeth 36 are defined which mesh with the teeth of pinion gear 30. Thus, in the well known manner, rotation of the pinion 30 by either a crank or a motor will rotate the gear sector 34 about its pivot axis shaft 32.

The gear sector 34 also includes a portion in which notch 38 is defined. The notch 38 includes an entrance opening 40, and a portion 42 defining a hook for purposes which will be later appreciated. A cam follower 44 is mounted on the gear sector adjacent the toothed periphery of the sector, and a cam surface 46 concentric with the shaft 32 is defined on the gear sector for locking the vent window in the fully retracted position as will be later described.

Two window panel operating levers are mounted upon the pivot axis shaft 32 for oscillation thereon. The first lever 48 is associated with the vent window panel 14 and includes an outer end upon which the roller 50 is mounted for reception within the vent window panel track 20. Thus, as the lever 48 is pivoted about its axis, the vent window 14 will be raised and lowered in its guide tracks. In a like manner, the primary window panel lever 52 is mounted upon the axis shaft 32 and includes a roller 54 received within the window track 22 such that pivoting of the lever 52 will raise and lower the window panel 16 in the known manner.

A bell crank lever 56 is pivotally mounted on the base plate 26 by a pivot shaft 58, and the bell crank lever includes a roller pin 60 constituting an abutment which is selectively receivable within the notch 38. The bell crank lever also includes a pivot pin 62 pivotally connecting link 64 thereto, and the other end of the link 64 is pivotally connected at 66 to the arm 68 of the vent window lever 48. Thus, it will be appreciated that the bell crank lever 56 is connected to the lever 48 through the linkage 64 for producing actuation of the lever 48 in dependence upon the position of the bell crank lever. Also, the dimensions between the roller pin 60 and the shaft 58, and the shaft 58 and the pin 62, as well as the dimension between the pin 66 and the shaft 32, are such that a multiplication of extent of movement is produced, i.e., movement of the bell crank lever 56 through an arc of approximately 60 will actuate and move the vent lever 48 through an arc of approximately 90.

A latch 70 is mounted upon the primary panel lever 52 and ispivotally affixed thereto by the pivot pin 72. The latch 70 is preferably biased in a counterclockwise direction with respect to rotation about the pivot pin 72 by a spring 74 as shown in FIG. 3. The latch includes a cam slot 76 in which the gear sector mounted cam follower 44 is received. The cam follower 44 includes a washer 78 of a diameter greater than the slot 76 which engages the latch side adjacent the slot, and the portion of the cam follower within the slot is of a diameter substantially corresponding to the slot width. The cam slot 76 includes a circular portion 80 having a radius equal to the radius of the cam follower 44 from the shaft 32, and the cam slot further includes a portion 82 transversely disposed to the portion 80. The intersection of the two cam slot portions is represented at 84.

The latch 70 serves as a lost motion interconnection between the gear sector 34 and the lever 52, and further serves to lock the lever 52 with respect to the vehicle door structure under certain conditions. Such locking is achieved by a detent block 86, which is fixed with respect to the vehicle door 12. While it is possible to mount the detent 86 upon the base plate 26, in the preferred embodiment, the detent block will be mounted upon the door structure 12 by suitable adjustable means such that the detent may be accurately located. Thedetent block includes a tapered surface 88, and an opposed positioning'surface 90, and a complimentary shaped notch 92 is defined in the latch 70 for closely cooperating with the detent block 86 in order to accurately and firmly maintain the lever 52, and the primary window panel 16 in its closed condition-with a predetermined force. The latch 70 includes an extended finger 94 upon which the surface 96 is defined, and the finger extends outwardly from the latch for cooperation with the detent block 86 in a manner later described.

Operation of the multiple stage window regulator in accord with the invention will be appreciated from the following:

Assuming the window panels 14 and 16 to be in their upper or closed positions, the window regulator structure will be in the relationships as represented in FIG. 1. In this condition the lever 52 is locked with respect to the detent block 86 as the detent block is closely received within the notch 92 of the latch 70. The latch'70 cannot pivot in the counterclockwise direction to remove the detent block from the latch notch due to the presence of the cam follower 44 within the slot portion 80, and the detent block 86 is so positioned that the window panel 16 will be maintained in its up or closed position with sufficient force to meet operational requirements with respect to sealing and comply with government safety regulations. Thus, the presence of the detent block 86 permits the window panel 16 to be held in the closed position with sufficient force to prevent water leakage past window seals, and rattling or other undesirable vibrations of the window panel will be eliminated.

In the relationship shown in FIG. 1, the bell crank lever roller pin 60 is located within the hooked portion 42 of the gear sector notch 38, and the notch surface 98 will be bearing upon the pin 60 endeavoring to rotate the lever 56 in a counterclockwise direction. Such a force on a lever 56 transmits a clockwise force onthe lever'48 tending to hold the vent window 14 in its uppermost position as shown.

When it is desired to lower the vent window 14 the operator rotates the pinion gear 30, either manually, or by motor, to rotate the gear sector 34 in a clockwise direction. This operation causes the notch hook portion 42 to be engaged by the roller pin 60 rotating the crank lever 56 in a clockwise direction. Due to the interconnection by the link 64, the lever 48 is now rotated at an accelerated rate in a counterclockwise direction which will lower the vent window 14. As will be appreciated by comparing FIGS. 1 and 2, the arc of movement through which the gear sector 34 rotates to pivot the lever 48 from its fully up position shown in FIG. 1 to the full lower position shown in FIG. 2 may be only in the neighborhood of 10 to 15, while approximately a oscillation is produced in the lever 48. This portion of rotation of the gear sector 34 producing operation of the lever 48 is hereinafter designated as the gear sector first arc of movement for purpose of reference.

From FIG. 2 it will be appreciated that as the gear sector is rotating through its first arc of movement to lower the window vent 14, the cam follower 44 is moving through the circular latch slot portion 80. However, as the latch slot portion 80 is concentrically related to the axis shaft 32 when the latch 70 is in locking relationship with the detent block 86, movement of the gear sector to produce vent window operation causes no movement of the latch with respect to the lever 52.

The crank lever 56 includes a cam follower surface 100 formed by a flange turned inwardly with respect to the viewer which lies within the plane of the gear sector 34, however, interference between the lever cam follower 100 and the gear sector does not occur during the previously described operation in view of the fact that the gear sector is recessed at 102 FIG. 6, in order to permit unimpeded rotation of the lever 56 during vent window panel operation.

When the vent lever 48 reaches its full down position, the roller pin 60 aligns with the notch entrance opening 40, and further rotation of the gear sector 34 in the clockwise direction permits the pin 60 to leave the notch 38, disengaging the lever 56, link 64 and lever 48 from the gear sector. As this position represents the lowermost position of the vent window 14, stop means, not shown, will normally be included in the window structure against which the vent window rests, and continued rotation of the gear sector 34 causes the gear sector cam surface 46 to engage the crank lever cam follower surface 100 and thereby lock the levers 56 and 48 in this lower position, preventing the vent window 14 from moving upwardly, or bouncing" in its guides due to impacts or vibration occurring during the normal use of the automobile. As will be appreciated from the drawings, the cam follower surface 100 is in engagement with the gear sector cam surface '46 at'all times except when the lever 48 is interconnected to the gear sector through the associated link 64, lever 56 and notch 38.

After the vent window 14 has been fully retracted the second sequence of operation begins. The beginning of this sequence is illustrated in FIG. 3 wherein the cam follower 44 has moved into the cam slot intersection 84 of the latch 70. Upon the cam follower 44 entering intersection 84 the cam follower will engage the cam surface 104 of the portion 82 and simultaneously begin pivoting the latch 70 in a counterclockwise direction about pivot pin 72 and imposing a force upon the latch which tends to move the lever 52 in a clockwise direction. Thus, the combined counterclockwise direction of rotation the latch 70 on the lever 52 tending to remove the notch 92 from the detent block 86, and the tendency of movement of the lever 52 in a clockwise direction permits the detent block and the latch notch to be separated which unlocks the lever 52 and permits the main window panel 16 to begin lowering.

FIG. 4 illustrates the position at which the notch 92 has substantially released the detent block 86 and the cam follower 44 has partially moved into the cam slot portion 82. Continued clockwise rotation of the gear sector 34 fully retracts the latch 70 to the position shown in FIG. 5, and the cam follower 44 will move to the end of the cam slot portion 82 under the influence of spring 74 pivoting the latch. Further clockwise rotation of the gear sector 34 continues to pivot the lever 52 in the clockwise direction as the follower 44 bears on surface 104 lowering the window panel 16 to its fully lowered position. The relationship of the window regulator components at the fully lowered position of the main window panel 16 is shown in FIG. 6.

It will be noted from FIGS. 4 through 6 thatduring the entire movement of the gear sector 34 through its second arc of movement constituting the operation of the lever 52 that the gear sector cam surface 46 is disposed adjacent the cam follower surface 100 of the lever 56 to lock the vent window panel 14 in its down or open condition.

When it is desired to raise the window panel 16 the operator reverses the direction of rotation of the pinion gear 30 to rotate the gear sector 34 in the counterclockwise direction, and the partially raised condition is now represented in FIG. 5. Lifting of the lever 52 occurs through the cooperation of the cam follower 44 with the latch cam slot portion 82, and a positive interconnection between the gear sector and lever 52 is achieved during raising of the window panel 16 due to an over center relationship between the follower 44 and the latch pivot pin 72 causing the follower to bear against the end of the cam slot portion 82 during lifting. The spring 74 insures that the latch will be properly oriented to the follower 44 while the panel 16 is in the lowered position to produce a positive lift on the lever 52 when the gear sector is rotated counterclockwise.

As the lever 52 approaches the detent block 86 the surface 96 of the finger 94 will engage the detent surface 90, FIG. 4, and further counterclockwise rotation of the lever 52 causes the latch 70 to pivot in a clockwise direction about its pivot pin 72 restoring the locking condition between the latch and the detent block 86 as represented in FIGS. 1 and 2. As soon as the latch notch 92 and the detent block 86 are fully engaged, the window panel 16 will be locked in its up position with the desired force.

If, after raising of the window panel 16, it is also desired to raise the vent window panel 14, continued rotation of the gear sector 34 in the counterclockwise direction causes the roller pin 60 to enter the notch 38 through opening 40, and the gear sector thereby picks up the operation of the lever 48. As the pin 60 is received-within the notch 38 it engages the notch surface 98 causing sufficient rotation of the lever 56 to fully position the pin within the notch, and at this time the recess 102 formed in the gear sector 34 has aligned with the cam follower surface 100 so that counterclockwise rotation of the bell crank lever is possible, as shown in FIG. 2.

As continued movement of the gear sector 34 in the counterclockwise direction continues, the lever 48 is pivoted in a clockwise direction raising the vent window panel 14 to the closed condition shown in FIG. 1, and upon the vent window being fully raised the window regulator operation is stopped.

It will be appreciated from the foregoing description that two separate and distinct stages of operation are produced each time the gear sector 34 is moved through its complete cycle of oscillation in either direction. The lost motion interconnection between the lever 48 and the gear sector 34 insures that the window 14 will only be operated during movement of the gear sector through its first arc of movement, and the configuration of the latch cam slot 76, and the use of the latch as a locking element cooperating with detent block 86, insures that the lever 52 will not move until the vent window operation is completely terminated and the gear sector moves into its second arc of movement operating the primary window panel.

During rotation of the gear sector through its second arc of movement the sector is disconnected from the lever 48 except with respect to the locking action produced by cam surface 46 and cam follower surface 100 which prevents lifting of the vent window.

Locking of the vent window in its open position, and locking of the primary window panel 16 in its upper position is automatically achieved by the window regulator requiring no attention by the operator. By accurately positioning the detent block 86 a closing force of relatively high magnitude may be maintained upon the window panel 16 without requiring excessive forces being imposed upon the window regulator due to the mechanical advantages existing within the cam slot portion 80 with respect to the tendency to pivot the latch upon the lever 52 due to forces imposed thereon through the detent block.

It is appreciated that various modifications to the inventive concept may be apparent to those skilled in the art without departing from the spirit of the invention.
