- the connecting rod 37 terminates in a push button 38 which projects slightly from the knob 15 of the arm rest 4 and which is under the effect of a compression spring 39 arranged within the arm rest 4.
- the spring 39 normally urges the locking pawl 35 continuously toward the stopping rail 33 and therewith into the respective notch provided therein whereby the window pane 7 is secured in every position against any undesired movement or displacement.
- the locking pawl 35 is lifted out of engagement from the particular notch of the stopping rail 33.
- the window pane 7 may then be readily raised or lowered at will by displacing the arm rest 4 longitudinally and therewith also the carriage 10.
- window pane 7 has been illustrated as a window which is slidable upwardly and downwardly, it is also understood that the arrangement described in connection with FIGURES 1 to 3 may be used with horizontally slidable windows or with a window pivotal about an axis, for example, about a vertical axis. Furthermore, instead of being slidable in a horizontal direction, the arm rest 4 may also be displaceable in a direction inclined, for example, upwardly forwardly, or, for example, along an essentially flat are or curve along the vehicle inner wall by means of a conventional parallelogram guide system.
- FIGURES 4 through 9 differs from that of FIGURES 1 to 3 in that the arm rest 4' thereof used for actuating the window pane 7', instead of being slidable along a rectilinear path, is pivotally arranged to either raise or lower the Window.
- reference numeral 7' designates again a window pane which is slidably guided along the lateral edges thereof in the vehicle door 5' in any conventional manner so as to be slidable upwardly or downwardly.
- the lowering or raising of the window 7' thereby takes place by means of a conventional lifting arm (FIGURE 9) in a manner Well known in itself.
- the lifting arm 110 is provided at the free end thereof with a guide roller 108 which engages in a slot 109' provided in the lower window rail 109 whereas the other end 111 of arm 110 (FIGURE 5) together with a toothed gear 118 (FIGURES 4, 5 and 9) rigidly secured therewith is pivotally supported on a pin 120 (FIGURE 5).
- the pin 120 forms a rigid coaxial continuation or extension of a further sonically-shaped bearing pin 122 (FIGURE 5) provided with a disk-shaped collar 113.
- the two pins 120 and 122 are connected over collar 113, for example, by welding, with a securing bow member 121 which is fixedly secured at the inner wall 112 of the door 108, for example, by means of bolts and nuts (FIGURE 5).
- the arm rest 4' which may be generally of similar external configuration as the arm rest 4 in FIGURE 1, is carried near the rear end 114 (FIGURE 5) thereof by a bearing bushing 127 rigidly connected therewith.
- the bearing bushing 127 carries at the outer end thereof facing the toothed gear 118 an entrainment lever 116 (FIGURES 5, 6, 7, 8 and 9) rigidly connected therewith.
- the sleeve 127 and therewith the arm rest 4' are pivotally supported on the conical pin 122 in a bore 130 of the entrainment lever 116 and in a bushing 129 inserted in sleeve 127 (FIGURE 5).
- the sleeve 127 and therewith the arm rest 4 are secured against axial movement by a disk 124 secured by means of a cotter pin 125.
- the entrainment lever 116 is provided at the free end 132 (FIGURE 8) on both sides thereof with bearing lugs 136 for a pin 134 which carries at one end thereof a double-acting locking pawl 117 (FIGURES 6 to 9) cooperating with the toothed gear 118 and at the other end thereof a pivot lever 135.
- the pivot lever 135 forms a toggle switch for the locking pawl 117 together with a U-shaped bow member (FIGURES 7 and 8) which is pivotally secured at the entrainment lever 116 by means of a pin 142, which carries a compression spring 143 and which engages with the slotted free end 139 thereof with a cross pin 137 of the lever 135.
- the toggle switch assembly operates in a manner well known per se.
- the tooth 133 of the locking pawl 135 In one end position of the toggle switch (FIGURE 6), the tooth 133 of the locking pawl 135 is in engagement with a tooth of the toothed gear 118 whereby the pivotal arm rest 4' during movement thereof in the clockwise direction is forcibly coupled with the toothed gear 118 and therewith with the lifting arm 110.
- the other tooth 133 of the locking pawl 135 engages in a tooth of the toothed gear 118 and thereby establishes a positive coupling between the lifting arm 110 and the arm rest 4' during movement thereof in the counterclockwise direction.
- the control of the toggle switch takes place by an actuating linkage arranged in part within the arm rest 4'.
- the actuating linkage consists of a connecting rod 151 in operative engagement at one end thereof with the knee point 137 of the toggle switch and provided at the other end thereof at 151 with a rectilinear guide means, andv of a Bowden cable 151) secured to the rectilinear guide means which terminatesin a push button 148 corresponding to push button 38 of the embodiment'according to FIGURES l to 3.
- the arm rest 4' is provided with a handle-like knob 145, corresponding to Knob 15 of.
- FIG- URES 1 to 3 from which projects the push button 148 which ordinarily is under the effect of a compression spring 149 arranged within the arm rest 4 (FIGURE 9).
- the arm rest 4 is thereby seized at the knob 145 thereof and is pivoted upwardly into the position 4" thereof indicated in dot and dash lines in FIGURE 9 without depressing the button 143.
- the entrainment lever 116 rigidly connected therewith takes along by means of the locking pawl 117 the toothed gear 118 in the counterclockwise direction whereby the arm 11! raises the window pane 107.
- the arm rest 4' may thereby be pivoted to such an extent until the entrainment lever 116 with the rear edge thereof abuts at 144' against the securing bow member 121 (FIGURE 6).
- the arm rest 4 thereupon is again pivoted back to the normal rest position thereof.
- the tooth 133' of the locking pawl 117 thereby disengages from the teeth of the toothed gear 118 and slides thereover without taking along the toothed gear 118 since the window pane 7' temporarily encounters sufiicient friction in the lateral guide means thereof and furthermore, since it may be supported in a known manner by a spring (not shown) balancing the weight thereof. If necessary, the disengagement of the locking tooth 133 from the teeth of the toothed gear 118 may be aided slightly by a slight pressure on the push button 148. If the window pane 7 is to be raised further, then the previously described steps are repeated once or several times.
- the window pane 7' In the normal position of the arm rest 4', the window pane 7' cannot be lowered again even by the application of external forces since, in order to be lowered, the window 7' would have to rotate over the arm 110, the toothed gear 118 and the locking pawl 117 would have to rotate the entrainment member 116 in the clockwise direction which, however, is prevented by the abutment thereof at the securing bow member 121 as at 144.
- the arm rest 4' is again lifted by upward pivotal movement thereof to approximately the position 4" thereof whereby the entrainment lever 116 moves from the position illustrated in FIGURE 6 in dot-and-dash line into the position indicated therein in full line in which it abuts with the rear edge thereof at 144 against the securing bow member 121 whereas the locking tooth 133 slides ineifectively over the teeth of the gear 118, i.e., without engaging the same.
- the tooth 133 of the locking pawl 117 establishes a positive connection between the arm rest 4 and the arm and thereby lowers the window pane 7' by a predetermined amount which amount may be increased at will by a repetition, either once or several times, of the last-described window lowering steps.
- the arm rest 4' In the rest position (FIGURE 9), the arm rest 4', by reason of the particular contour of the knob 145, simultaneously serves as handle for closing the door or as handle rail for the person sitting adjacent thereto during starting or stopping of the vehicle as well as during traversal of curves.
- FIGURES 10 and 11 The particular configuration of the arm rest 4', which may also be the configuration of the arm rest 4 of FIGURE 1, is shown in FIGURES 10 and 11.
- the push button 148 is provided in the cuspshaped portion of the knob 145.
- the arm rest 4- is provided with a trough-shaped portion 104 at the forward part thereof.
- the arm rest 4 itself may be provided with a covering of any suitable material covering, for example, a layer of foam latex.

(Cl. 296-44) The present invention relates to a mechanism for imparting movement to slidable windows, especially in motor vehicles, and more particularly relates to an actuating mechanism including an arm rest provided along the inside of the door of the passenger space for either opening or closing a window in motor vehicles as well as automatically locking the window in any particular, desired position.
The known window actuating mechanism of the prior art which are manually actuated for purposes of opening and closing vehicle windows required separate actuating members such as cranks, knobs, levers or the like arranged at the vehicle inner wall in proximity to the seats. Such actuating members thereby projected relatively far into the vehicle interior space and formed hard protruding parts with sharp edges which oftentimes prove annoying to the passengers when leaning against the vehicle inner walls or doors, which are a potential source for damaging the passengers clothing or which also may cause injuries to the vehicle passengers during sudden braking, accidents or hard impacts.
Accordingly, it is an object of the present invention to eliminate the aforementioned disadvantages in a particularly simple and efficacious manner.
It is another object of the present invention to provide a window actuating mechanism which utilizes the arm rest at the inner vehicle wall itself for purposes of imparting the desired movement to the vehicle window.
A still further object of the present invention is to provide a window actuating mechanism which minimizes dangers and annoyances to the passengers by eliminating parts of the actuating mechanism which project inwardly into the passenger space.
Still another object of the present invention is the provision of a simple, yet reliable window actuating mechanism which at the same time automatically locks the window in any desired position.
It is a still further object of the present invention to provide a window-actuating mechanism which in addition to the advantages enumerated hereinabove, provides a kinematic connection of the arm rest with the window actuating movement which produces a very advantageous construction as well as a means for locking the window in any desired position by very simple means.
These and other objects, features and advantages of the present invention will become more obvious from the following description when taken in connection with the accompanying drawing which shows, for purposes of illustration only, several embodiments in accordance with the present invention and wherein:

FIGURE 10 is a side elevational view of an arm rest for use with both embodiments of a window actuating mechanism in accordance with the present invention, and
FiGURE 11 is a plan view of the arm rest shown in FIGURE 10. t
The present invention consists essentially in a window actuating mechanism which utilizes an arm rest for purposes of actuating the mechanism whereby the arm rest is movably secured at the inner vehicle wall and is operatively connected with the actuating mechanism.
In one embodiment according to the present invention, the arm rest is arranged to be movable in the longitudinal direction thereof to cause the window actuating move ment.
In another embodiment according to the present invention the arm rest is pivotally secured at the inner wall of the door to produce by pivotal movement thereof the required actuating movement for opening or closing the window.
Referring now to the drawing, wherein like reference numerals are used throughout the various views to desig nate like parts, and more particularly to the first embodiment shown in FIGURES 1 to 3, reference numeral 5 generally designates a vehicle door in which the window pane 7 is guided along the lateral edges thereof in any conventional manner so as to be movable upwardly and downwardly. An angle lever 26 serves for purposes of raising or lowering the window pane 7. This lever 26 is pivotally supported at the apex thereof by means of a pin 27 in a base plate 18 (FIGURES 2 and 3) rigidly connected in any suitable manner with the inner door wall generally designated by reference numeral 6. The longer arm 28 of the angle lever 26 carries at the free end thereof a cross pin 29 which is slidingly guided in a slot 19 provided at the lower window frame or ledge for the window pane 7.
One end of draw spring 31 which balances the weight of the window pane 7 engages the downwardly directed shorter arm 30 of the angle lever 26. The other free end of the spring 31 is suitably secured at the base plate 18 as at 32.
The free end of the shorter arm 30 is further pivotally connected with one free end of a connecting rod 25 in any suitable manner. The other end of the connecting rod 25 is pivotally connected with a U-shaped, bent, pressed or stamped sheet-metal part 23 (FIGURES 2 and 3). The U-shaped bent sheet-metal part 23 projects through a slot 24 in the base plate 18 (FIGURES -2 and 3) and is rigidly connected with its one arm, for
example, by welding, with a carriage which is longitudinally movably supported at the base plate 18 so that the window pane 7 is raised or lowered during displacement of the carriage 10 by means of the connecting rod 25 and the angle lever 26.
Two angle irons 8 and 9 are securely arranged at the base plate 18 for purposes of guiding the carriage 10. Of these angle irons 8 and 9, the upper angle iron 8 is provided with a guide channel 12 for two pairs of balls 17 which are retained at the ends of the carriage 10 in boss-like pressed-out cups 16. The lower angle iron 9 is surrounded at the U-shaped bent free edge 13 thereof by a correspondingly shaped profiled strip 20 made of self-lubricating synthetic material, for example, of nylon (FIGURE 3). The strip 20 is pressed against the edge 13 of the angle iron or guide rail 9 by means of a corrugated bent leaf spring 21 which abuts against the channel-shaped lower rim of the carriage 10 so that the carriage 10 cannot rattle in the guide arrangement thereof.
The carriage 10 is provided with two protuberances 11 of truncated conical shape, to which an upholstered arm rest 4 arranged at the inside of the vehicle door is secured. The arm rest 4 carries at the forward end thereof a knob for purposes of carrying out to-and-fro movement of the carriage 10 in the guide arrangement thereof and therewith for purposes of raising and lowering the window pane 7. The general configuration of the arm rest 4 may be of any suitable construction but preferably is of the type to be more fully described by reference to FIGURES 10 and 11 in connection with the embodiment of FIGURES 4 to 9.
In order to assure that the window pane 7 can be safely retained in any position thereof and at any desired height, a means in the form of a locking pawl 35 is arranged at the carriage 10 which is adapted to engage with the notches provided in a stopping rail 33 secured to the base plate 18. The locking pawl 35 is secured to a lever 34 which in turn is pivotally secured at 32 to the pressed sheet-metal part 23 of the carriage 10 andwhich projects through a slot 36 of the carriage 10 into the arm rest 4.
A connecting rod 37 is pivotally connected to the free end of the lever 34. The connecting rod 37 is guided along the inside of the arm rest 4 in a manner to be freely movable in the longitudinal direction thereof. The connecting rod 37 terminates in a push button 38 which projects slightly from the knob 15 of the arm rest 4 and which is under the effect of a compression spring 39 arranged within the arm rest 4. The spring 39 normally urges the locking pawl 35 continuously toward the stopping rail 33 and therewith into the respective notch provided therein whereby the window pane 7 is secured in every position against any undesired movement or displacement. By applying a slight pressure on the push button 38, the locking pawl 35 is lifted out of engagement from the particular notch of the stopping rail 33. The window pane 7 may then be readily raised or lowered at will by displacing the arm rest 4 longitudinally and therewith also the carriage 10.
While the window pane 7 has been illustrated as a window which is slidable upwardly and downwardly, it is also understood that the arrangement described in connection with FIGURES 1 to 3 may be used with horizontally slidable windows or with a window pivotal about an axis, for example, about a vertical axis. Furthermore, instead of being slidable in a horizontal direction, the arm rest 4 may also be displaceable in a direction inclined, for example, upwardly forwardly, or, for example, along an essentially flat are or curve along the vehicle inner wall by means of a conventional parallelogram guide system.
The embodiment according to FIGURES 4 through 9 differs from that of FIGURES 1 to 3 in that the arm rest 4' thereof used for actuating the window pane 7', instead of being slidable along a rectilinear path, is pivotally arranged to either raise or lower the Window.
Referring now to FIGURES 4 through 9 and more particularly to FIGURE 4, reference numeral 7' designates again a window pane which is slidably guided along the lateral edges thereof in the vehicle door 5' in any conventional manner so as to be slidable upwardly or downwardly. The lowering or raising of the window 7' thereby takes place by means of a conventional lifting arm (FIGURE 9) in a manner Well known in itself. The lifting arm 110 is provided at the free end thereof with a guide roller 108 which engages in a slot 109' provided in the lower window rail 109 whereas the other end 111 of arm 110 (FIGURE 5) together with a toothed gear 118 (FIGURES 4, 5 and 9) rigidly secured therewith is pivotally supported on a pin 120 (FIGURE 5). The pin 120 forms a rigid coaxial continuation or extension of a further sonically-shaped bearing pin 122 (FIGURE 5) provided with a disk-shaped collar 113. The two pins 120 and 122 are connected over collar 113, for example, by welding, with a securing bow member 121 which is fixedly secured at the inner wall 112 of the door 108, for example, by means of bolts and nuts (FIGURE 5).
The arm rest 4' which may be generally of similar external configuration as the arm rest 4 in FIGURE 1, is carried near the rear end 114 (FIGURE 5) thereof by a bearing bushing 127 rigidly connected therewith. The bearing bushing 127 carries at the outer end thereof facing the toothed gear 118 an entrainment lever 116 (FIGURES 5, 6, 7, 8 and 9) rigidly connected therewith. The sleeve 127 and therewith the arm rest 4' are pivotally supported on the conical pin 122 in a bore 130 of the entrainment lever 116 and in a bushing 129 inserted in sleeve 127 (FIGURE 5). The sleeve 127 and therewith the arm rest 4 are secured against axial movement by a disk 124 secured by means of a cotter pin 125.
The entrainment lever 116 is provided at the free end 132 (FIGURE 8) on both sides thereof with bearing lugs 136 for a pin 134 which carries at one end thereof a double-acting locking pawl 117 (FIGURES 6 to 9) cooperating with the toothed gear 118 and at the other end thereof a pivot lever 135. The pivot lever 135 forms a toggle switch for the locking pawl 117 together with a U-shaped bow member (FIGURES 7 and 8) which is pivotally secured at the entrainment lever 116 by means of a pin 142, which carries a compression spring 143 and which engages with the slotted free end 139 thereof with a cross pin 137 of the lever 135.
The toggle switch assembly operates in a manner well known per se. In one end position of the toggle switch (FIGURE 6), the tooth 133 of the locking pawl 135 is in engagement with a tooth of the toothed gear 118 whereby the pivotal arm rest 4' during movement thereof in the clockwise direction is forcibly coupled with the toothed gear 118 and therewith with the lifting arm 110. In the other end position of the toggle switch (FIGURE 9), the other tooth 133 of the locking pawl 135 engages in a tooth of the toothed gear 118 and thereby establishes a positive coupling between the lifting arm 110 and the arm rest 4' during movement thereof in the counterclockwise direction. In the intermediate dead-center po-' sition of the toggle switch, in which the cross pin 137 lies in the line 141 (FIGURE 6) connecting the two pins 134 and 142, the force-locking engagement between the lifting arm 110 and the arm rest 4' is interrupted.
The control of the toggle switch takes place by an actuating linkage arranged in part within the arm rest 4'. The actuating linkage consists of a connecting rod 151 in operative engagement at one end thereof with the knee point 137 of the toggle switch and provided at the other end thereof at 151 with a rectilinear guide means, andv of a Bowden cable 151) secured to the rectilinear guide means which terminatesin a push button 148 corresponding to push button 38 of the embodiment'according to FIGURES l to 3. The arm rest 4' is provided with a handle-like knob 145, corresponding to Knob 15 of. FIG- URES 1 to 3, from which projects the push button 148 which ordinarily is under the effect of a compression spring 149 arranged within the arm rest 4 (FIGURE 9).
In the approximately horizontal normal position of the arm rest 4 illustrated in FIGURE 9, the entrainment member 116 rigidly connected therewith by the bearing sleeve 127 abuts with the forward edge thereof at 144 (FIGURES 5 and 6) against the securing bow member 1.21 so that the arm rest 115 during use thereof as arm rest, properly speaking, is able to withstand also, without yielding, a considerable pressure exerted thereon from above. Simultaneously therewith, the control linkage 148-159" is also in the normal rest position thereof independent of the prevailing position of the window pane 7' in which normal rest position the tooth 133' of the locking pawl 117 engages with the toothed gear 118.
OPERATION The upward or downward movement of the window pane 7' takes place by corresponding pivotal movement of the arm rest 115 in the following manner:
Raising of the Window Pane for Purposes of Closing the Window The arm rest 4 is thereby seized at the knob 145 thereof and is pivoted upwardly into the position 4" thereof indicated in dot and dash lines in FIGURE 9 without depressing the button 143. During the upward movement of the arm rest 4 the entrainment lever 116 rigidly connected therewith takes along by means of the locking pawl 117 the toothed gear 118 in the counterclockwise direction whereby the arm 11!) raises the window pane 107. The arm rest 4' may thereby be pivoted to such an extent until the entrainment lever 116 with the rear edge thereof abuts at 144' against the securing bow member 121 (FIGURE 6). The arm rest 4 thereupon is again pivoted back to the normal rest position thereof. The tooth 133' of the locking pawl 117 thereby disengages from the teeth of the toothed gear 118 and slides thereover without taking along the toothed gear 118 since the window pane 7' temporarily encounters sufiicient friction in the lateral guide means thereof and furthermore, since it may be supported in a known manner by a spring (not shown) balancing the weight thereof. If necessary, the disengagement of the locking tooth 133 from the teeth of the toothed gear 118 may be aided slightly by a slight pressure on the push button 148. If the window pane 7 is to be raised further, then the previously described steps are repeated once or several times. In the normal position of the arm rest 4', the window pane 7' cannot be lowered again even by the application of external forces since, in order to be lowered, the window 7' would have to rotate over the arm 110, the toothed gear 118 and the locking pawl 117 would have to rotate the entrainment member 116 in the clockwise direction which, however, is prevented by the abutment thereof at the securing bow member 121 as at 144.
Lowering of the Window Pane To Open the Window At first, by applying pressure to the push button 148, the locking tooth 133' is lifted from the engaged position thereof with the gear 118 and the locking pawl 117 for purposes of tipping over is brought into the position illustrated in FIGURE 6. In the position illustrated in FIGURE 6, the locking tooth 133 now engages the toothed gear 118. Therenpon, the arm rest 4' is again lifted by upward pivotal movement thereof to approximately the position 4" thereof whereby the entrainment lever 116 moves from the position illustrated in FIGURE 6 in dot-and-dash line into the position indicated therein in full line in which it abuts with the rear edge thereof at 144 against the securing bow member 121 whereas the locking tooth 133 slides ineifectively over the teeth of the gear 118, i.e., without engaging the same. If now the arm rest 4' is again pivoted downwardly from its po- 6 sition 4" into the normal rest position thereof, then the tooth 133 of the locking pawl 117 establishes a positive connection between the arm rest 4 and the arm and thereby lowers the window pane 7' by a predetermined amount which amount may be increased at will by a repetition, either once or several times, of the last-described window lowering steps.
In the rest position (FIGURE 9), the arm rest 4', by reason of the particular contour of the knob 145, simultaneously serves as handle for closing the door or as handle rail for the person sitting adjacent thereto during starting or stopping of the vehicle as well as during traversal of curves.
The particular configuration of the arm rest 4', which may also be the configuration of the arm rest 4 of FIGURE 1, is shown in FIGURES 10 and 11. As pointed out above, the push button 148 is provided in the cuspshaped portion of the knob 145. In order to properly accommodate the palm of the hand of the passenger during actuation of the window actuating mechanism, the
arm rest 4- is provided with a trough-shaped portion 104 at the forward part thereof. The arm rest 4 itself may be provided with a covering of any suitable material covering, for example, a layer of foam latex. The position of the passengers hand during use of the arm rest 4' is shown in phantom lines in FIGURE 11. This figure shows the convenient rest position which is afforded by the particular configuration of the arm rest 4 for purposes, not only of actuating the window actuating mechanism, but also for purposes of utilizing the arm rest as hand rail to close or open the door or brace the passenger during starting or sudden braking.
It is also understood again that the window actuating mechanism of FIGURES 4 to 9, though shown in connection with a slidable window which is slidable in the vertical direction, may also be used for purposes of actuating a window which is slidable in the horizontal direction or which may be pivotal about an axis, for example, a vertical axis.
