1 Claim.
This invention relates to a regulator mechanism particularly adapted for vthe windows" of automobiles although it can be' used to advantage for other purposes', and an object is to improve regulator mechanisms of'this character to adapt them to nt conveniently in. a limited amount of space and to improve their'str'uctural features, to enhance their' operation and to produce a simple and eiii'cient mechanism of' this character lending' itself admirably' to large scale manufacturing' operations;
Other objects and advantages. of" the invention will hereinafter appear; andfor purposes of illustration but not' of limitation, an embodiment ofthe invention is shown on' thel accompanying. drawing', inv which Figure 1 is a side elevation'of a regulator mechanism showing the'v same operatively connected toa vehicle window panel; and.
Figure 2 is an edge' or' plan viewofthe regulator shown in Figure 1, viewedfrom the lower or under sider thereof'.
The illustrated embodiment oithe invention comprises a regulator mechanism W for actuating` a window panel orglass Pl'of an automobile, the mechanism being adapted'tov be mounted in the well and suitablyisecured; to'. a rigid part of the door or body structure. e
Embracing the lower edge ofthe window panel P. is. the usual U-shaped channel I0, from the under side' of which depends a. bracket Il which is vertically slotted to receive boltv and nut assemblies for securing a bar I2 having retainer element I3 fixed thereto. The retainer elements have horizontally elongate slots or guides to receive studs Ill which are secured to the free outer ends of bell cranks I6 and I'I, a spring tensioned washer being mounted on each stud I4 to cooperate with the retainer for eliminating rattles and holding the associated parts in the desired guiding relation. The bell crank I'I has a relatively long arm I5 carrying the stud I4 and is embossed outwardly at I8. The bell crank Il has a relatively short arm I9 projecting at approximately 90 therefrom.
At the juncture of the long arm I5 and the short arm I9, the bell crank I'I is pivoted at 2i) to a stanchion or side bar 2|. The bell crank i 5 has a relatively short arm 22 of approximately the same length as the short arm I9 of the bell crank il and a relatively long arm 23. The free end of the short arm I9 of the bell crank Il is pivoted to the juncture of the short arm 22 and long arm 23 at 24. The free end of the short arm 22 is pivoted at 25 to a stanchion 26. The
2 long" arm 23 is embossed outwardly at 2 1 and the end portion terminates in a downwardly cuifi'felil portion 28, the free end being pivoted at` 29 to a compensating lever 30 which is pivoted at one end to the stanchion 26 at 3|, the free end ofthe arm 3l] overlapping the stanchion 2'I and being limited in its clockwise movement bya pin 32 pro- Viding a stop therefor. rIlhe stanchions ZI and 26 are joined at one end by across bar 33 to which the stanchion 2 I` is pivoted at 34 for swing@ ing movement towardand away from the stanchion 2 6. The stanchion `26 is Secured byA two rivets 35 to the cross bar 33 in a rigidl manner' to hold it against relative r-novem'ent.` l e Actuation of the bell cranks I6 and I'I is eff; f'ecteol in one direction by a linear motor which: in this instance is inthe form of a cylinder 36,- having a piston reciprocable therein provided" with a piston rod 3l' connected by a fastener 38" to the short arm 22 of the bell crank II.= v The"` opposite end of thecylinder hasr a-ftting 39pmvided with a post lll whichis con-nected by ar fase tener 4I to the compensating arm 30 on thee'n'ds pcrtion thereof adjacent its pivot 3|.r
By embossing the long arms I5 and 2-3 of the bell cranks in the manner shown and described;
the bell cranks are enabled toswing during their?` operative movement without interfering with each other. The downwardly curving of thearm' 23- as aboveA described, enables the use of a shorter arm and one that does notl interfereA with the` cylinder 38 so that a greater window movement can be achieved with a relatively small mechanism. This is further advantageous in that the regulator unit occupies a relatively small amount of space and can be fitted into a Window well where the space requirements are exceedingly small.
Fluid such as liquid under pressure is admitted to the cylinder 36 through the inlet 42 of the fitting 39 to drive the piston to the right of Figure 1, thereby to cause the bell crank I6 to rock in a clockwise direction and the bell crank Il in a counterclockwise direction. In this manner, the window panel P is caused to move upwardly, the studs I4 moving laterally in the slotted retainers I3. During such upward movement of the window panel P, a helical coil spring t2, one end of which hooks around the outer end portion of the compensating arm and the other end of which hooks around an intermediate portion of the short arm I9 of the bell crank I'I, is placed under tension so that upon release of the pressure fluid from the cylinder 36, the tensioned coil spring 42 imparts opposite swinging movement to the bell cranks I6 and l1 thereby causing the window panel P to move downwardly. It is to be understood that iluid such as liquid supplied under pressure by a pump to the cylinder 36 and by suitable valve means, the fluid within the cylinder is trapped after the window has been moved to a predetermined extent.
Manifestly, by suitable control of such valve mechanism and the rendering of the pump ineffective, the coil spring 42 is enabled to be effective for accomplishing window movement. The compensating arm 30 functions to militate against damage to the window panel P or regulator parts when the window is in closed position and in the event of expansion of the fluid within the cylinder 36. The operation of the uid motor, the coil spring, the compensating arm is fully shown and described in previous patents of mine, such, for example, as 2,346,387, dated April 11, 1944, 2,371,183, dated March 13, 1945, and 2,393,409, dated January 22, 1946. These features per se form no part of the present invention and further description or illustration thereof is not considered necessary.
The above regulator mechanism is designed to t into small places without sacricing the desired window movement. The arrangement of the bell crank levers is such as to eiect the maximum travel with the expenditure of a minimum amount of power. The arrangement of the linear motor and the curvature of the adjacent bell crank arm assist in the conservation of space. The entire mechanism can be preassembled and installed as a unit on the job, it being merely necessary to attach the cross bar 33 to a desired support, and in order to hold the mechanism rigidly and resist forces imparted during operation, it is also feasible to secure the lower sv'tanchion 26 also to a rigid support.
It is to be understood that numerous changes in'details of construction, arrangement and operation inay be effected without departing from the spirit of the invention especially as defined in the appended claim.
What I claim is:
A regulator mechanism for vehicle windows mounted for up and down movements between lowermost and uppermost positions comprising a horizontally disposed frame lying substantially in one vertical plane and including a vertically disposed flat cross bar and upper and lower flat frame arms connected at one end to said cross bar, one frame arm being pivotally connected to said cross bar, a vehicle window and supporting elements disposed therebeneath, said window and supporting elements being substantiallyat and lying substantially in a vertical plane parallel and closely spaced from said first plane, said supporting elements including substantially hori zontally disposed slideways, a pair of bell crank levers, each lever having a relatively short arm, a relatively long arm, and an angularv juncture of said long and short arms, a sliding connection between the free ends of the long arms of said levers and the slideways, a pivotal connection between the juncture of one of said levers and said upper frame arm, the arrangement being such that when said window is in lowermost position the long arms of said levers extend downwardly and the supporting elements for said window lie adjacent the level of said lower frame member, a pivotal connection between the free end of the short arm of the other lever andsaid lower frame arm, a pivotal connection between the juncture of said other lever and the free end of the short arm of said one lever, the long arms of both of said levers including lateral offsets adjacent said junctures whereby said short arms and junctures lie substantially in the first plane and the free ends of said long arms extend substantially from the rst plane to the second plane, and a linear motor engaging the short arm of said other lever, said motor including a cylinder overlying between said lower frame member but havng'a side thereof lying between said planes whereby when said window is in said lowermost position, a straight line from the juncture of said other lever to the free end of the long arm thereof passes through said side, the last-named long arm having a downward hook adjacent the free end thereof whereby the lateral olset'and the hook cooperate with one another to avoid interference between the lastnamed long arm and said cylinder side.
