7 Claims., (Cl. 26S- 124) The present invention relates tol-an improved Window actuating mechanism of the type particularly adapted for Peter W. Wozena,'Detroit,
use with an automobile. Morespeciically,V the"pr'e sent invention relates to a window actuating mechanism which is capable of positioning a'raised'window in substantially flush relation with the outer door or body'panelwith which it is associated. Y
y Forreasons of window storage andfcomplication of ll the operating mechanism, it has beenvthe practice in Ythe past to mount vehicle windows somewhat inboard 'of the outer door or body panel with which they are associated. In addition to the improved appearance which obtains with a ush mounted type window, functionalfadvantages are realized also. With windows which are" set inboard from the outer door or bodypanel, 'it necessary`- to provide sealing means to'keep water from seeping within the door and which means frequently detracts from the vehicles appearance. propensity for collecting or admitting water between the window and door is substantially eliminated.
The subject window' operating mechanism includesl means for vertically raising and loweringthe window and With a flush type window the 71 uniquely kcombines therewithmeans for translating or Figures 2 through 4 are sectlonal views along lin'c l of Figure l showing the window in variouspositions;
Figure 5 is a view along line 5-5 of Figure 2; Figure 6 is a view along line 6-6 of Figure lZ; Figure 7 is a view along line'7-7 of Figure 2f and Figure 8 is a view along line 8--8 of Figure 4.
y, Patented Apr. Y11, 1951 and a guide extension 30 at its upper end. Inboard guide 20 also has aguide extension 32 at its upper end.
A depending plate 34 is secured to the lower edge of window 14 and includes a pair of laterally inwardly extending ears 36-and 38 each of which has aroller 40 and 42 respectively pivotally mounted thereon throughvpins 4 4 and 46. Rollers 40 and 42 move only in the outboard guide 22. A link 48 is pivotally secured` at one end to ear 36 through v`pin 44. The other end of link 48 is pivotally secured through a pin 50 to a roller 52 which is movable only inthe inboard guide 20.
A bellcrank 54 is'- pivotallyA secured through pin 46 to ear 38. Oneleg 56 of vbellcrank 54 is pivotally secured through a pinvr 58 to a roller 60 movable only in the inboard guide 20. The other leg 62 of bellcrank 54 includes a pin or follower 64 xed thereto. Follower pin 6 4 isr adapted to engage a cam surface 66 formed on the Voutboard. gu'ide`22 proximate the guide extension 28. A link l68'is pivotally secured yto link 48 through pin 50 and to bellcrankr 54' throughpin 58.
' Y'The links `68 associated with the respective guide sets at either sideof window 14 arel interconnected through a cross member70 toY which window actuating mechanism 16 is suitably articulated at points 72 and 74 as best seen Figure '1. f j Referring irstto Figure 2, when it is desired to lower window 14, link 68 isshifted downwardly so as to move the rollers 52 and I60- downwardly within the inboard guideKZUq/This movement kof link 68 pulls the rollers 40 and 42 Vout ofthe guide extensions 30 and 28 into vertically spaced' relationship with rollers 52 and 60 as Will best be 'seen in Figures 3 and 4. This inboard shiftingrof rollers 40 -and 42 imparts a similar shifting movement to window 14 shifting the latter inboar'dy of door 12 sov that the lower edge of the window is moved out of abutting relationship with the door outer panel 76.
Thereafter, further downward movement of links'68 willA cause window 14 to move 4downwardly within door12 toits fully lowered position as seen in Figure 4.`
When vwindow 14 is moved to its up position, the rollers move along the respective guides 28 and 22 in their vertically spaced relationship until pin 64 engages cam surface 66 of the outboard guide 22. Thereafter continued upward movement of link 68 causes the bellcrank '54 to swing about its pivot 46 in a counterclockwise direction to move roller 42 into extension 28 of guide 22 1 and toA horizontally align roller 60 therewith in guide 20.
Simultaneously with this movement of bellcrank 54, roller 40 will ralsofbe moved into the extension 30Y of guide 22' androller 52 into extension 32 of guide 20 to locate:V these rollersin horizontal aligned relationship Referring first to Figure l,` a vehicle is indicated generally at 10 and includes a door 12 within which'a window 14 is adapted to be mounted for verticalraising and lowering.` By means of structure to'bevsubsequently considered in greater detail, window 14 is connected with a conventional window raising and lowering mechanism indicated generally at 16. Window actuatingl mechanism 16 may either be manually controlled or, as illustrated in the drawings, controlled by an electric motor and gear sector device indicated generally at 18.
Referring more specifically to Figures 2 through 4, inboard and outboard guides 20 and 22 are mounted in any suitable manner on the door side. panel 24 as through 4the bracket device indicated generally at 26 in Figure 5. I
A pair of inboard and outboard guides 20 and 22 are provided at each side of window 14. Each of the guide sets are of identical construction, therefore, only one set willlbe described. v
lt will be noted that the guides 20 and 22 are generally aligned at their lower portion. Outboard guide 22 has a guide extension 28 approximately intermediate its length and to move the window to its up position. At the same time window 14 is shifted outboard into ilush relation with door panel 76.
Arseal strip 78 is cemented to window plate 34 and coacts with the upper edge 80 of door panel 76 to seal and cushion therwindow in its closed position.
As seen in Figures l and 2, anY upper window channel y82 is adapted to abut against a seal strip 84 secured to Y A pair of aligned snubber devices 88 and 9G are respectively mounted on the inner and outer panels 92 and 76 of door 12 to resiliently support window 14 in its lateral movement relative to the door. Snubbers 38 and 90`are essentially identical and include piston members 94 and -96 slidably disposed in cylinders 98 and 100. Each of the pistons 94 and 96 is biased toward window plate 34 byak spring 102.r The pistons also include roller members'104 and-106 suitably mounted thereon'so that the action of the snubbers in no way inhibits the up and down f movement ofthe window.
A spring biased hinge cover 108 is provided to provide access into the door well. Cover 108 is biased in a closing or outboard direction when window 14 is 1n its down position since the opening 110 otherwise necessarily provided to permit the lateral movement of window 14 would be large and unsightly. As window 14 is shifted laterally inwardly preliminarily to lowering the same, cover 108 is likewise moved laterally or inboardV to accommodate such window movement. A seal strip 112 is secured along the outer edge of cover 108.
