DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Selected embodiments of the present invention will now be explained with reference to the drawings. It will be apparent to those skilled in the art from this disclosure that the following descriptions of the embodiments of the present invention are provided for illustration only and not for the purpose of limiting the invention as defined by the appended claims and their equivalents.
Referring initially to FIG. 1, a vehicle 10 is illustrated that is equipped in accordance with one embodiment of the present invention. The vehicle 10 includes a plurality of vehicle doors 12. One of the doors 12 is shown removed from the vehicle 10 in FIG. 2 to provide greater clarity. As shown in FIG. 2, each of the vehicle doors 12 includes a window regulator mechanism 14 with a lifter plate 16 that includes a water deflecting structure 18. The water deflecting structure 18 is configured to divert water away from various portions of the window regulator mechanism 14 in order to reduce potential degradation typically associated with water infiltration, such as corrosion of metallic parts, as described in greater detail below.
As shown in FIG. 2, the vehicle door 12 basically includes, among other things, a door body 20 generally formed by an inner support panel 22 and an outer panel 24. A window opening 26 is formed by an upper frame of the door body 20. The vehicle door 12 also has a pair of parallel window tracks 28 mounted to the door body 20. In FIG. 2, a portion of the outer panel 24 has been cutaway to reveal the inner support panel 22, the window regulator mechanism 14 and portions of the window tracks 28. The two window tracks 28 are installed on opposite sides of the window opening 26. A window panel G that is preferably made of safety glass is installed in the door body 20 between the window tracks 28 for up and down sliding movement along the tracks 28. Movement of the window panel G is controlled by the window regulator mechanism 14, as described in greater detail below. The window panel G has a lower edge 29 that includes lower outer edge 29a (FIG. 5) and a lower inner edge 29b (FIG. 5).
As shown in FIGS. 2 and 3, the window regulator mechanism 14 basically includes a window regulator rail 30, a cable 32, a pair of Bowden type cable tubes 34, a power mechanism 36, and the lifter plate 16. Other than the construction of the lifter plate 16, as discussed below, the window regulator mechanism 14 is a relatively conventional mechanism that is well known in the art. Thus, the window regulator mechanism 14 will only be briefly discussed and illustrated to explain the present invention.
The window regulator rail 30 resembles a hollow tube that has an elongated a channel 40, a pair of pulleys 42 and a pair mounting brackets 44. As shown more clearly in FIGS. 4, 5 and 6, the channel 40 has a hollow interior 50 and an elongated opening or slit 52. As shown in FIG. 3, the pulleys 42 are spaced apart from one another with one of the pulleys 42 being installed at the top of the window regulator rail 30 within the channel 40, and the other of the pulleys 42 being installed at the bottom of the window regulator rail 30 within the channel 40.
The mounting brackets 44 are configured for mounting the window regulator rail 30 to the inner support panel 22 of the vehicle door 12. The mounting brackets 44 (and the window regulator rail 30) are preferably mounted to the inner support panel 22 using fasteners, such as bolts or rivets. However, it should be understood from the drawings and the description herein the window regulator rail 30 can be mounted directly to a portion of the vehicle frame, for instance when the vehicle is a two door coupe with a back seat that includes windows adjacent to a back seat.
As shown in FIG. 3, the cable 32 extends through the channel 40, around each of the pulleys 42, through the Bowden type cable tubes 34 and through the power mechanism 36. The Bowden type cable tubes 34 extend from respective ones of a top and bottom portion of the window regulator rail 30 adjacent to respective ones of the pulleys 42 and to the power mechanism 36.
The power mechanism 36 is a conventional mechanism that can be either an electric motor (power windows) or a hand crank mechanism that is configured in a conventional manner to transmit rotary power to the cable 32. The cable 32 is connected to the lifter plate 16, as described in greater detail below. Hence, movement of the cable 32 causes the lifter plate 16 to move along the channel 40 of the window regulator rail 30 thereby raising or lowering the window panel G along the window tracks 28 in and out of the window opening 26.
As best shown in FIGS. 3 to 6, the lifter plate 16 basically includes a main body 60, a pair of window glass support portions 62 and a window regulator engagement portion 64. The water deflecting structure 18 is integrally formed with the main body 60 of the lifter plate 16. The parts of the lifter plate 16 can be made of any of a variety of materials such as metal, plastic or polymer materials as needed and/or desired.
Still referring to FIGS. 3 to 6, the main body 60 includes an inboard surface 60a, an outboard surface 60b, a front edge 60c (FIG. 4) and a rear edge 60d (FIG. 4). The main body 60 is preferably a one-piece, unitary member that is formed as a molded plastic member. The window glass support portions 62 are configured to support the lower edge 29 of the window panel G. Each of the window glass support portions 62 basically includes a mounting aperture 66 (shown in FIG. 3 only) that is formed in the main body 60 and a window panel attachment member 70. The window panel attachment members 70 are configured and arranged to engage the lower edge 29 of the window panel G at a pair of spaced apart locations. As best shown in FIGS. 4 and 5, the window panel attachment members 70 are each formed with grooves that receive the lower edge 29 of the window panel G in a conventional manner. Although not shown, the window panel attachment members 70 can include a clamping device for firmly engaging the window panel G and/or a rubber-like friction insert placed within the groove to retain the window panel G. Fasteners extend through apertures formed in the window panel attachment members 70 and further through the apertures 66 in the window glass support portion 62 of the lifter plate 16 to secure the window panel attachment members 70.
As best shown in FIGS. 5 and 6, the window regulator engagement portions 64 are basically projections extending from the inboard surface 60a of the main body 60 of the lifter plate 16. The window regulator engagement portions 64 are configured to be slidably mounted within the hollow interior 50 of the channel 40 such that the lifter plate 16 can slid along the window regulator rail 30 of the window regulator mechanism 14.
It should be understood from the drawings and the description herein that the window regulator engagement portions 64 can be formed integrally with the lifter plate 16 or, alternatively, can be separate elements that are attached to the lifter plate 16 by fasteners, adhesive materials, or welding, depending upon the material used to make the lifter plate 16.
As best shown in FIGS. 5 and 6, the window regulator engagement portions 64 basically include a first lateral extension 74, a second lateral extension 76, a cable clamping portion 78 and a slit extension 80. Since the window regulator engagement portions 64 are generally the same, description of only one is provided for the sake of brevity, but applies to both.
As best shown in FIG. 6, the first lateral extension 74 and the second lateral extension 76 are dimensioned to slide smoothly within the hollow interior 50 of the channel 40 of the window regulator rail 30. The cable clamping portion 78 is shown as an aperture formed within the first lateral extension 74, but can be formed in any of a variety of ways. Specifically, the first lateral extension 74 can be a separate element that is attached to the window regulator engagement portion 64 by fasteners (not shown) thereby clamping the cable 32 in position relative to the main body 60 of the lifter plate 16. The slit extension 80 is basically a narrowed portion of the window regulator engagement portion 64 that extends to the main body 60 through the elongated opening or slit 52.
The window regulator engagement portions 64 are preferably coated with a friction reducing material or lubricant, such that the window regulator engagement portions 64 slide easily and relatively friction free within the hollow interior 50 of the channel 40 of the window regulator rail 30.
Referring to FIGS. 4 and 5, a description of the water deflecting structure 18 is now provided. The water deflecting structure 18 is configured and arranged to deflect water running down the window panel G away from the window regulator rail 30. The water deflecting structure 18 basically includes a first water deflecting surface 82 and a second water deflecting surface 84. The first and second water deflecting surfaces 82 and 84 are integrally formed with the main body 60 as a one-piece, unitary member.
The first water deflecting surface 82 is defined on an outwardly extending ridge 90 that extends from the outboard surface 60b of the main body 60 of the lifter plate 16. The first water deflecting surface 82 further extends in a direction that is transverse to movement of the window regulator engagement portion 64 of the main body 60 along the window regulator rail 30. The outwardly extending ridge 90 is an elongated protrusion extending from the outboard surface 60b of the lifter plate 16. Consequently, the first water deflecting surface 82 together with adjacent portions of the outboard surface 60b of the lifter plate 16 defines a gutter that diverts water from the water deflecting surface 82 toward at least one of the front edge 60c and the rear edge 60d of the lifter plate 16.
The first water deflecting surface 82 extends in a forward to aft direction and is consequently further configured and arranged to divert water to at least one side of the window regulator rail 30 in the forward to aft direction. The outwardly extending ridge 90 has three portions, a forward inclined portion 92, a central portion 94 and a rearward inclined portion 96. The central portion 94 extends in a direction that is approximately parallel to the length of the window regulator rail 30, the forward inclined portion 92 is inclined downward away from the window regulator rail 30 and the central portion 94 toward the front edge 60c (FIG. 4), and the rearward inclined portion 96 is inclined rearward away from the window regulator rail 30 and the central portion 94 toward the rear edge 60d. As can be seen in FIG. 4, the first water deflecting surface 82 extends in a forward to aft direction from proximate the first of the two window panel attachment members 70 to proximate the second of the two window panel attachment members 70.
The first water deflecting surface 82 has a convex shape configured to divert water in directions extending away from the window regulator engagement portion 64. Consequently, the first water deflecting surface 82 is configured and arranged to divert water to opposite sides of the window regulator rail 30 in the forward to aft direction and configured to deflect water toward at least one of the front edge 60c of the lifter plate 16 and the rear edge 60d of the lifter plate 16. It should be understood from the drawings and the description herein that the forward inclined portion 92, the central portion 94 and the rearward inclined portion 96 can also alternatively be formed as a continuous curved projection shaped to divert water away from the window regulator rail 30.
As indicated in FIG. 5, the second water deflecting surface 84 is configured to deflect water running down the window panel G toward the outboard surface 60b of the lifter plate 16. The second water deflecting surface 84 is further configured to deflect water running down the window panel G toward the first water deflecting surface 82. The second water deflecting surface 84 has an upper end 98 (see FIG. 5) that is disposed inboard of the lower inner edge 29b of the window panel G and a lower end 100 disposed approximately outboard of the lower outer edge 29a of the window panel G. The second water deflecting surface 84 is disposed between the first and second window panel attachment members 70 and above the first water deflecting surface 82. As such, the second water deflecting surface 84 is configured to deflect water running down the window panel G toward the first water deflecting surface 82. The second water deflecting surface 84 is also inclined such that it slopes downwardly in a direction towards the first water deflecting surface 82.
It should be understood from the drawings and description herein that the second water deflecting surface 84 can be formed as an inclined surface on a separate element that is secured to the lifter plate 16, or alternatively, the second water deflecting surface 84 can be integrally formed with the lifter plate 16 as a single element or member.
The various portions of the door 12 and vehicle 10 are conventional components that are well known in the art. Since vehicle and door portions are well known in the art, these structures will not be discussed or illustrated in detail herein.
