FIELD OF THE INVENTION
The present invention relates to a movable panel assembly with a power sliding drive mechanism. More particularly, the present invention relates to a movable panel assembly with a power sliding drive mechanism for a flush-flush closing vehicle sliding panel.
BACKGROUND OF THE INVENTION
Pickup trucks and other related vehicles have a rear window, or backlite, that is mounted in a vehicle body aperture, immediately behind the seats in the vehicle passenger compartment. Many of the backlites are built with one or two slider panels that ride in slider tracks, while opening or closing across a portion of a window aperture.
The slider panels may be moved manually or automatically across the window aperture. When automatically driven, the slider panels may be moved by a window regulator, for example, like that disclosed in U.S. Pat. No. 6,119,401 to Lin (hereinafter Lin).
For the Lin device, there is a cable having a powered regulator attached to one cable end and a carrier block that is physically attached at another cable end, wherein the carrier block has a female carrier socket. In conjunction with the carrier block, an attachment block is rigidly mounted to a slidable window pane, wherein the attachment block has a male engagement stud that is loosely disposed within the female carrier socket. Consequently, when the Lin window regulator is powered for movement of the cable, the carrier socket and the engagement stud come into mating engagement that results in sliding movement of the slidable window pane. Such an arrangement is noisy, where the powered window regulator loosely drives the slidable window pane. Because of the many parts involved, the Lin window regulator has high material and labor costs.
Some slider assemblies are further designated as being flush where a sliding panel is in the plane of the fixed panel(s), when the sliding panel completely closes the backlite opening, or the complete window assembly may be in the plane of a vehicle body panel. Various ways to achieve flush orientation to fixed panels are, for example, by utilizing guide pins, ramps, and cams to move the sliding panel into the backlite opening.
An example of a horizontal sliding assembly that moves its sliding panel into the plane of a fixed panel, when the sliding panel completely closes the backlite opening, is U.S. Pat. No. 4,561,224 to Jelens (hereinafter, Jelens), which teaches a sliding window assembly having opposed longitudinally spaced first and second guide pins on the top and bottom of a slidable window that are adapted for sliding motion within corresponding first and second tracks respectively, as shown, for example, in Jelens' FIGS. 2-5 and 7.
Even further, some sliding assemblies are designated as being flush-flush, wherein the sliding panel is not only flush within the sliding assembly itself (i.e., the sliding panel being in the same plane as fixed panels) but the sliding assembly would also be in the same plane as an outer vehicle body panel. U.S. Pat. No. 7,641,265 to Seiple (hereinafter Seiple) is an example of a flush-flush sliding assembly, which is incorporated herein by reference in its entirety.
What is sought is a powered sliding assembly that directly, smoothly, and with less resistance drives a sliding panel with little noise. While achieving these benefits, it is desired for such a powered sliding assembly to be simple in design, thereby having few parts in order to reduce material and labor costs. Such a sliding assembly should also be capable of being flush-flush in design.
SUMMARY OF THE INVENTION
A powered sliding drive assembly is provided having a fixed panel that defines a window opening, a sliding panel that is movable between a closed position covering the window opening and an open position. The sliding panel has a frame member secured around at least a portion of the periphery of the sliding panel, wherein the sliding panel defines a plane. The powered sliding drive assembly also has at least one guide pin extending substantially vertically downwardly from a portion of the frame member, which is disposed on a bottom portion of the sliding panel. There is also at least one cable connected at a first end to the guide pin, to the frame member, or to both, and a second end connected to a sliding panel drive unit. As a result, at least the first end of the cable is in the plane of the sliding panel.
The powered sliding drive assembly may further be provided with at least one track, wherein the sliding panel has at least one pin positioned in the track and the sliding panel is located in a flush-flush position with a fixed panel and a vehicle body panel. The pin may also have a washer disposed on it, thereby providing smooth and quiet movement of the sliding panel.
Further objects and advantages of the present invention will be apparent from the following description and appended claims, reference being made to the accompanying drawings forming a part of a specification, wherein like reference characters designate corresponding parts of several views.

Although the above descriptions of FIGS. 1-13 involve a single lower right corner of the sliding assemblies 10, 30, 50, 70, 90, 110, 130, 150, 170, 190, 210, 230, the same descriptions apply to a lower left corner of the sliding assemblies 10, 30, 50, 70, 90, 110, 130, 150, 170, 190, 210, 230, which assemblies would reciprocally be pulled from left to right, and then be pulled from right to the left by the drive unit 290, for opening and closing a fixed panel opening.
To summarize, the powered slider panel assemblies 10, 30, 50, 70, 90, 110, 130, 150, 170, 190, 210, 230 of the present invention have a sliding panel 25, 45, 65, 85, 105, 125, 145, 165, 185, 205, 225, 245, 285 that defines a window opening (like opening 313) and a sliding panel 10, 30, 50, 70, 90, 110, 130, 150, 170, 190, 210, 230 that is movable between a closed position covering the window opening 313 and an open position, where the sliding panel has a frame member 12, 32, 52, 72, 92, 112, 132, 152, 172, 192, 212, 232, 272, 314 secured around at least a portion of the periphery of the sliding panel, and the sliding panel along with a frame defines a plane. There is at least one guide pin 16, 36, 56, 76, 96, 136, 156, 176, 196, 216, 276a-d extending substantially vertically downwardly from a portion of the frame member which is disposed on a bottom portion of the sliding panel and there is at least one cable 18, 38, 58, 78, 98, 102, 118, 122, 138, 158178, 198, 222, 218, 242, 238, 278a-d connected at a first end to the guide pin, to the frame member, or to both, and a second end of the cable is connected to the sliding panel drive unit 290, wherein at least the first end of the cable is in the plane of sliding panel 10, 30, 50, 70, 90, 110, 130, 150, 170, 190, 210, 230, which includes the corresponding frame member.
The above described sliding assemblies 10, 30, 50, 70, 90, 110, 130, 150, 170, 190, 210, 230 may be operated as a vehicle window assembly that could be categorized as non-flush, flush, or flush-flush. With regard to a flush-flush vehicle window assembly, FIG. 14 shows a sliding assembly 270 with all four corners being capable of being operated as a flush-flush sliding panel assembly 270 having a frame 272, four pins 276a-d, two cables 278c,d (for bidirectional control by the drive unit 290), and a sliding panel 285. In addition, there are two tracks 282, 284 that have respective paths 286, 288 disposed within. The cables 278c,d may be connected to the frame 272 or any of the pins 276a-d. For the sliding panel assembly 270, the pins 276 are required to be longer than those in the Seiple device, in order to extend through the corresponding tracks 282, 284.
It is noteworthy that the paths 286, 288 are different than those of Seiple, which are illustrated in Seiple's FIG. 15 as paths 328, 329, wherein the present invention paths 286, 288 are connected together, while the paths 328, 329 (with corresponding upper paths that are not shown but similar to paths 28a, 29a of Seiple) are separate from one another. Both sets of paths 286, 288 and 328, 329, however, are capable of positioning the sliding panel assemblies 10, 30, 50, 70, 90, 110, 130, 150, 170, 190, 210, 230, 270 into a flush-flush orientation.
The pins 16, 36, 56, 76, 96, 136, 156, 176, 196, 216, with or without washers 34, 74, 114, 154, 194, 234, slide similarly as the various pins of Seiple. If the pins 276a-d are longer than a thickness H′ (see FIG. 14) of the tracks 282, 284, while in the order of the dimensions H1-H4 that are illustrated in FIGS. 3-6, 11 and 12, then the pins 276a,b,c,d may accommodate the washers 74, 114, 194, 234 and collars 178, 200, 220, 240, thereby allowing the cables 58, 78, 102, 122, 178, 198, 218, 238 to function as intended.
Hence, the present invention provides powered sliding assemblies that directly and smoothly drive sliding panel assemblies having little noise. While achieving these benefits, such powered sliding assemblies are simple in design, thereby having few parts which reduce material and labor costs. The few parts being realized in the present invention is a result of directly attaching the sliding panel assemblies 10, 30, 50, 70, 90, 110, 130, 150, 170, 190, 210, 230, 270 to the drive unit 290, via the pulleys 292, 294. In the case of the prior art powered sliding assemblies, the cables are directly attached to a separate device like Lin's carrier block, which in turn indirectly attaches to an attachment block that is connected to a sliding panel assembly.
In addition, the sliding panel assemblies 10, 30, 50, 70, 90, 110, 130, 150, 170, 190, 210, 230, 270 of the present invention can be incorporated into the flush-flush track and path design of the Seiple patent. FIG. 15 of the present invention is essentially prior art FIG. 1 of Seiple, where a horizontal vehicle sliding window assembly 310 comprises two fixed panels 311, 312 with the window opening 313 therebetween.
An opening frame 314 defines the window opening 313 and upper and lower tracks 315, 316 are disposed respectively above and below the window opening 313. Shown in the lower track 316 are separate paths 328, 329 that can locate the sliding panel assemblies 10, 30, 50, 70, 90, 110, 130, 150, 170, 190, 210, 230, 270 of the present invention into a flush-flush position with respect to the fixed panels 311, 312 and the vehicle body panel 144 (see FIG. 13). Although hidden from view, there are equivalent paths in the upper track 315 as FIG. 2 of Seiple illustrates. Consequently, the sliding panel assemblies 10, 30, 50, 70, 90, 110, 130, 150, 170, 190, 210, 230, 270 of the present invention can take advantage of the prior art structure of the flush-flush horizontal vehicle sliding window assembly 310.
With the washers 34, 74, 114, 154, 194, 234 installed on the pins 36, 76, 116, 156, 196, 236, as illustrated in FIGS. 2, 4, 6, 8, 10, 12, the sliding panel assemblies 30, 70, 110, 150, 190, 230 can slide across the surface 289 of the track 282 and a surface 318 of the track 316 smoothly, with less resistance, and reduced noise being generated.
Also, the sliding panel assemblies 10, 30, 50, 70, 90, 110, 130, 150, 170, 190, 210, 230, 270 of the present invention can be incorporated into a single fixed panel assembly 400, as shown in FIG. 16. The single fixed panel assembly 400 has a single fixed panel 402 with a window opening 404, where anyone of the sliding panel assemblies 10, 30, 50, 70, 90, 110, 130, 150, 170, 190, 210, 230, 270 is movable on tracks, for example, tracks 282, 284, 315, 316, between a closed position covering the window opening 404 and an open position. The single fixed panel assembly 400 cooperates with a frame member, for example, frames 12,32, 52, 72, 92, 112, 132, 212, 232, 272, secured around at least a portion of the periphery of a sliding panel, for example, sliding panels 25, 45, 65, 85, 105, 125, 145, 165, 185, 205, 225, 245, 285.
In accordance with the provisions of the patent statutes, the principles and modes of operation of this invention have been described and illustrated in its preferred embodiments. However, it must be understood that the invention may be practiced otherwise than specifically explained and illustrated without departing from its spirit or scope.
