Application June 10, 1932, Serial No. 616,511
RElsSuEu 16 Claims. (01. 268--126) This invention relates to regulators or controlling mechanisms for windows, particularly for use in motor vehicles or the like, an object of the invention being to provide improved means of relatively simple, economical and durable construction for raising and lowering the window.
A further object of the invention is to provide an improved window regulator or mechanism especially adapted for installation, for example,
w in the body or door of an automobile, and in which improved gear mechanism is provided for operating a pair of swinging arms adapted to be connected to the lower edge of the window.
A further object of the invention is to provide an improved Window regulator of the type having a pair of swinging arms for raising and lowering the window and wherein the arms are, operated through the medium of improved gearing including a compound gear preferably formed from a single metal blank to provide two gears of different diameters.
The invention possesses further objects and advantages, all of which will be brought out in the following detailed description, illustrated throughout the accompanying drawing, and more particularly pointed out in the appended claims.
With reference to the drawing:
Figure l is a front elevation of the device with the supporting plate partially broken away exposing a part of the gears and the connecting arms to the glass broken away as indicated.
Figure 2 is a section taken substantially upon line 55 of Figure 1.
Figure 3 is a section taken substantially upon 3 line 6-6 or Figure 1.
In accordance with the present preferred form of the invention, herein illustrated by way of example, there is provided asupporting plate 1 which is secured within the door of the vehicle by the customary wood screws, and the metal of the supporting plate is provided with the usual screw bosses having holes 2 for the reception of the attaching screws. The plate 1 is also preferably reinforced by embossing 3. Mounted upon the supporting plate for swinging movement in opposite directions are a pair of bars "or lever arms 4 and 5, these arms being slidingly connected at their outer ends to metallic guide members 6 which are attached to the usual longitudinal metal channel secured at the lower edge of the window glass. The guide members 6 at the lower edge of the window are provided with elongated slots or openings '7 for the re-- ception of headed studs 8 riveted to the outer ends of the arms 4 and 5, as illustrated particularly in Fig. 3. The body portions or shanks of the studs 8 are adapted to slide freely between the upper and lower horizontal edges of the guide slots 7, and the connections between the parts aremaintained against rattling by means of metal cup washers 9, leather washers l0 and coil springs 11 interposed between the guide members 6 and the swinging arms and 5. The guide slots 7 preferably terminate at their adjacent inner ends in enlarged openings to permit inser- 55 tion of the headed studs 8 into the guide slots, as illustrated in dotted lines in Fig. l. 1
In the present embodiment of the invention the swinging arm or bar 4 is secured by rivet 13 to a compound gear which comprises an. outer gear segment 12 of relatively large diameter and a smaller gear 23 of relatively smaller diameter, these gears preferably being punched from the same metal blank. The compound gear 12, 23
is permanently fixed to a lateral shaft or pivot 14 rotatable in a suitable bearing 1'7 formed in the supporting plate 1. One end of the shaft or pivot 14 is secured to the arm 4 by riveting, as shown, and the opposite end has a slot within which is anchored one end of a double counterbalancing spring 16. The other swinging arm or bar 5 is,.in the present embodiment, secured to a gear 18 by means of a rivet l9, and it is also fastened as by riveting to the outer end of a shaft or pivot 20 rotatable in a suitable bearing 22 formed in the supporting plate. The inner end of the shaft or pivot 20 has a slot within which is anchored the other end of the double or compound spring 16. It will be understood that the compound gear 12, 23 is fixed to the stud or shaft 14 and the gear 18 is in turn fixed to the stud or shaft 20. The compound spring 16 comprises two similar sets of windings produced from a single metal strand, one end of the continuous spring being thus fastened to the stud 14 and the other end to the stud 20.
One of the important features of my invention is the provision of the compound gear comprising gears 12 and 23 of different diameters. In the present instance the gear 23 has the same diameter as gear 18 which meshes therewith. Gear sector 12 is also formed so that at the termination of its teeth there are provided positive stops 15 engageable with the connecting gear 18 to limit the rotating movement of gear 12 and thereby limit the operation of the arms both in lowering and elevating-the glass. Gear sector 12 also meshes with a gear 24 which is connected with gear 25, the gears 24 and '25 being permanently fixed to a lateral shaft 26. The metal of plate 1 is depressed to form a bearing 2'7 for the said shaft and this shaft has a shouldered end riveted over a plate 28. The metal of plate .1 isalso depressed or embossed upon its rear surface as at 29 to reduce the contact surface between the adjacent surfaces of plate 1 and gear 25. Gear 25 mesheswith a pinion 30 permanently fixed to a lateral shaft 31, the metal of plate 1 being depressed as at 32 to form a bearing for the outer end of said shaft. Asuitable crank handle of any conventional type (not shown) is connected to the inner end of shaft 31 so that upon turning the handle the arms 4 and 5 will be swung in opposite directions through the gearing to raise and lower the window. v
From the foregoing it will be seen that the swinging arm 4 is attached through its pivot or shaft 14 to a compound gear formed from a single metal blank, comprising a gear portion 23 having.
the same diameter as the gear 18 and also com prising a gear portion or sector 12 of largerdiameter which is driven from the operating handle 33 through the medium of gears 30, 25 and 24. The position of the terminal ends 15 ofgear sector 12 determines the range of swinging move-v ment of the arms 4 and 5 in both directionasince the ends. 15 provide stops effective upon engagement with gear 18 to limit the movement of the arms. This operation is obtained by reason of the fact that the gear portions 12 and 23 lie in a, common plane coincident with the plane of the gear 18. It will further be seen that I have provided a counterbalancing spring for the swinging arms, this spring being formed into two sets of reverse windings from a single continuous strand, one set being connected with each of the to which the lower end of one of the said bars. is secured, a second gear secured to the lower end of theother bar and having a toothed portion of the same diameter as that of the first-named gear and meshing with thesame, another portion of said second named gear having teeth formed so as to produce a gear of a greater diameter than the first named portion thereof.
