Background of the Invention
1. Field of the Invention
A bracket assembly is provided for mounting a loose upper deck panel onto a vehicle body, the bracket including a break-away spacer element which is used for properly locating the bracket with respect to the vehicle deck lid.
2. Prior Art
The bracket assembly of the present invention is provided for mounting a loose upper deck panel onto a vehicle body. Conventionally, a loose upper deck panel is used as an exterior body panel on a sedan-like car or similar vehicle. This panel is positioned between the rear vehicle window and the forward edge of the deck or trunk lid. It is necessary that the upper surface of the loose upper deck panel be in alignment with the upper surface of the deck lid so that these two elements will present a continuous surface appearance. If the upper surface of the loose upper deck panel is higher or lower than the surface of the deck lid, an objectional discontinuous surface appearance results.
Conventionally, a loose upper deck panel is mounted on the vehicle after the deck lid has been mounted. Proper positioning of the loose upper deck panel has been achieved in the manufacturing process by means of full-sized fixtures. The fixtures are used to properly locate the panel on the vehicle body. Such fixtures are quite expensive. Additionally, the tolerance range and the accuracy of such fixtures is frequently not as close as desired. Further, such fixtures are bulky and heavy and difficult to handle. This latter point results in relatively inefficient use of the time of production workers.
In accordance with the present invention, a bracket is provided for mounting loose upper deck panels which does not require the use of a fixture for proper location of the panel. This substantially reduces manufacturing costs and tends to improve the quality of the finished vehicle.
Positionment of the brackets is accomplished by providing a break-away spacer element extending rearwardly from the bracket for contact with the forward edge and upper surface of the previously mounted deck lid. Once the bracket has been properly located, it is fastened in place. The break-away nature of the spacer element permits easy removal of this element after the bracket structure is secured in place. The loose upper deck panel is then secured on the bracket structure. This permits lower cost installation plus custom tailoring of each panel which takes into account variances in the tolerances of a vehicle build. All vehicles are not dimensionally identical. Thus, it is desirable to locate panels on the vehicle with reference to the exact physical characteristics of the vehicle which, as above stated, inherently vary from vehicle to vehicle.
A similar locating technique is disclosed is U.S. patent application Ser. No. 07117,719, filed Oct. 6, 1987, now U.S. Pat. No. 4,786,094 issued Nov. 22, 1988. The presently disclosed structure differs therefrom in that both a vertical and horizontal positionment is achieved by means of two different locating surfaces and in that the bracket structure includes means for proper positionment of the panel after the bracket itself has been properly located.
Summary of the Invention
A bracket assembly for mounting a loose upper deck panel onto a vehicle body is provided. The vehicle body includes a rear window with a deck lid spaced rearwardly therefrom. The loose upper deck panel is mounted between the rear window and the forward edge of the deck lid. The vehicle includes a support shelf positioned between the rear window and the forward edge of the deck lid. The loose upper deck panel is generally U-shaped and includes an upper wall for extending transversely of the vehicle with forward and rearward walls depending downwardly therefrom. The loose upper deck panel is mounted on the vehicle with the upper surface of the upper wall thereof in alignment with the upper surface of the deck lid.
The bracket is generally U-shaped and includes a bottom wall for extending longitudinally on said support shelf of the vehicle with forward and rearward bracket walls extending upwardly therefrom. The forward bracket wall ha a protuberance on the rearward surface thereof. The forward wall of the loose upper deck panel has opening means therein. The protuberance extends through this opening means to secure the forward wall in the desired vertical location.
The rearward bracket wall has opening means therein. The rearward wall of the loose upper deck panel has mating opening means therein. Fastening means extend through these mating opening means to secure the rearward wall of the loose upper deck panel to the rearward bracket wall in the desired vertical location.
A spacer element extends rearwardly from the upper end of the forward bracket wall. The spacer element has a generally vertical locator surface for contact with the forward edge of the deck lid to locate the bracket a predetermined distance forwardly of the forward edge of the deck lid. The spacer element has a generally horizontal locator surface for contact with the upper surface of the deck lid to locate the bracket at a predetermined vertical orientation with respect to the upper surface of the deck lid. Shim structure is positioned between the bracket bottom wall and the support shelf to maintain said vertical orientation as needed. Fastening means secure the bracket bottom wall to the support shelf. The spacer element is joined to the rearward bracket wall by a frangible joint whereby the spacer element may be easily broken away from the rearward bracket wall after the bracket has been located and fastened in place on the support shelf.
Preferably, the frangible joint comprises a portion of the bracket wall of reduced thickness which is formed at the apex of a V-shaped notch structure with the apex defining a break line.

Detailed Description of a Preferred Embodiment
Referring to FIGS. 1 and 2, it will be noted that a loose upper deck panel 10 is positioned for mounting onto a vehicle 12, the vehicle being of the sedan type and including a rear window 14 and a deck or trunk lid 16. As is conventional, a space exists between the forward edge 18 of the deck lid 16 and the lower edge of the rear window 14. This space is conventionally filled, for exterior body purposes, by what is termed a loose upper deck panel, namely, the panel 10. The deck lid 16 is mounted onto the vehicle 12 prior to mounting of the panel 10 thereon. When the panel 10 is mounted, it is critical that the upper surface 20 of the panel 10 be in exact alignment with the upper surface 22 of the deck lid 16. If the panel 10 is too high or too low, an objectionable discontinuous body appearance results. The vehicle 12 includes a support shelf structure 24 which defines a portion of the inner body of the vehicle. The support shelf 24 extends in the space between the rear window 14 and the forward edge 18 of the deck lid 16.
The loose upper deck panel 10 is generally U-shaped as will be noted in FIGS. 1 and 3. The panel 10 includes an upper wall 26 which extends transversely of the vehicle 12. Forward and rearward walls 28, 30 extend downwardly from the forward and rearward edges of the upper wall 26. Spaced apart openings 32, 34, 36 are provided in the rearward wall 30. As will be later explained, these openings are for the purpose of mating with similar openings in brackets 38, 40, 42. A pair of elongated openings 44, 46 are provided in the forward wall 28 adjacent to the outer ends thereof to receive bracket protuberances as will be later described.
The brackets 38, 42 each have the same construction. These brackets, as will be noted in FIGS. 1, 2, 5 and 7, are generally U-shaped and include a bottom wall 48 which extends longitudinally of the support shelf 24 when the bracket is mounted in place. Forward and rearward bracket walls 50, 52 extend upwardly from the forward and rearward ends of the bottom wall 48. The forward bracket wall 50 has an elongated transverse protuberance 54 on the rearward surface 56. The protuberances 54 extend through the elongated openings 44, 46 provided in the forward wall 28 of the panel 10 when the panel 10 is mounted on the brackets. As will noted, the forward wall 28 of the panel 10 is received inside of the forward bracket wall 50 so that the protuberances may extend through the openings. This arrangement results in securing the forward wall 28 of the panel 10 in the desired vertical location, which location results in the upper surface 20 of the panel 10 being in alignment with the upper surface 22 of the deck lid 16.
The rearward wall 30 of the panel 10 is received on the outer surface of the rearward bracket wall 52 when the panel is set in place. At this point, the openings 32, 36 mate with the openings 58 provided in the rearward bracket wall 52. Sheet metal screws 60 are then screwed in place to result in fastening means securing the parts together. A cut out portion 62 is provided in the bracket bottom wall 48 adjacent to the opening 58 to receive the inner end of the sheet metal screw. Again, the mating nature of the openings in the panel 10 and brackets results in securing the rearward wall 30 of the panel 10 in the desired vertical location so that the upper surface 20 of the panel 10 will be in alignment with the upper surface 22 of the deck lid 16.
Prior to mounting of the panel 10 onto the brackets, the brackets are fastened to the support 24. The brackets are first positioned in the desired longitudinal and vertical position to result in the desired alignment of the surfaces 20, 22 as previously discussed. This positionment is accomplished by means of a spacer element 64 provided on the brackets 38, 42 and a spacer element 66 provided on the bracket 40. The construction of the spacer elements is substantially similar on both types of brackets. As will be particularly noted in FIG. 3, the spacer element 66 is provided in the form of a tab which extends rearwardly from the upper end of the rearward bracket wall 68. The spacer element has a generally vertical locator surface 70 for contact with the forward edge 18 of the deck lid 16 to locate the bracket a predetermined distance forwardly of the forward edge 18. The bracket is first set on the support shelf 24 and moved manually until the surface 70 contacts the forward edge 18. The spacer element 66 also has a generally horizontal locator surface 72 for contact with the upper surface 22 of the deck lid 16 to locate the bracket at a predetermined vertical orientation with respect to the upper surface of the deck lid. In many cases, it is necessary to provide a shim 74 beneath the bracket to raise the bracket to the desired elevation. Shims 74 are used as needed.
After the bracket has been properly located, it is secured in place by means of screws 76, 78 and 80, 82 which are received in elongated pairs of openings 84, 86 and 88, 90 of the bracket bottom walls 48, 92. The openings are elongated to permit the necessary fore and aft adjustment of the brackets for positioning the brackets in the proper longitudinal position with respect to the forward edge 18 of the deck lid 16 at previously described. Suitable opening structures 94, 96 and 98, 100 are provided in the support shelf structure 24 to receive the screws. The screws may be driven directly through the shim structures.
After the brackets have been properly located and secured in place, the spacer elements 64, 66 are removed. The brackets are preferably fabricated of a plastic material which is frangible, that is, will easily break. Each spacer element is joined to the bracket body by means of a frangible joint 102, 104. To obtain a frangible joint in the present invention, a portion of the bracket is of reduced thickness. This is obtained by means of providing V-shaped notches 106, 108 with the apexes defining break lines 110, 112. When the brackets are secured in place, the spacer elements are broken away and discarded. As will be noted, slots 114, 116 are provided in the spacer elements. The spacer element is bent outwardly as shows in dotted lines in FIG. 3 as by means of a screwdriver tip 118 until the joint fractures. After removal of the spacer elements, the loose upper deck panel is mounted as previously described.
The bracket 40 differs from the brackets 38, 42 in that a forward bracket wall is not provided and a central bracket wall 120 extends upwardly from the bottom wall 92 longitudinally thereof. The central bracket wall 120 functions to support the upper wall 26 of the panel 10, maintaining this wall at the proper vertical elevation. Because of the length of the panel 10, there may be a tendency for the center portion thereof to sag. As will be noted, one of the brackets 38, 42 is provided at each end of the panel 10 while the bracket 40 is provided as substantially the center thereof. A notch 122 is provided in the upper rearward corner of the wall 120. The notch 122 serves as a clearance space. An opening 124 is provided in the bracket rear wall 68 and receives screw 126 which extends through opening 34 of the panel rearward wall 30 to secure these parts together. Again, a cutout 128 is provided to receive the inner end of the screw 126. Again, the mating nature of the openings 124, 96 assures a proper positionment of the panel 10 with respect to the deck lid 16.
