DETAILED DESCRIPTION

(21) With reference to FIG. 1, a commercial vehicle, such as a tractor-trailer 10, is provided that includes a truck 12 connected to a trailer 13. The truck 12 includes a body 14 supported on wheels 16 and having a door 18. The door 18 may be opened to access an interior of the body 14. The truck 12 also includes a baggage door 20 that selectively closes an opening 34 of the body 14 and permits access to the interior of the body 14.

(22) With respect to FIG. 2, the baggage door 20 is shown from an interior perspective. The baggage door 20 includes an outer panel 24 and a hinge, such as an inner support 22 and a hinge base 26. The outer panel 24 is mounted to the inner support 22 and the inner support 22 includes a hinge portion 28 that cooperates with the hinge base 26 and a hinge pin 148 (see FIG. 3) to define an axis 30 about which the inner support 22 and outer panel 24 mounted thereto may pivot between open and closed positions.

(23) One or more of the components of the baggage door 20 are made of a non-metallic, such as plastic, material. For example, the inner support 22, outer panel 24, and hinge base 26 may be made of a plastic material that provides a reduced weight compared to traditional metal baggage doors while providing sufficient strength to withstand loads placed on the outer panel 24 when the outer panel 24 is in the open position. In one embodiment, the inner support 22, outer panel 24, and hinge base 26 are all made of one or more plastic materials. For example, the inner support 22 may be made of a glass filled polymer, the outer panel 24 is made of a polymer suitable for cosmetic applications, and the hinge base 26 may be formed from a glass-filled polymer. The material of the outer panel 24 is selected to provide sufficient rigidity for the outer panel 24 to compress a dust seal of the vehicle body 14 that extends about the opening 34. Further, the plastic materials of the inner support 22, outer support 24, and hinge base 26 reduce the weight of the baggage door 20, resist corrosion, and dampen vibration during operation of the tractor-trailer 10.

(24) By making the inner support 22, outer support 24, and hinge base 26 out of plastic material(s), the tolerances of the baggage door during manufacture may be improved because the components are not formed from stamped sheet metal. As one example, the inner support 22, outer panel 24, and hinge base 26 may be formed by injection molding plastic material which permits close tolerances to be maintained throughout a production run. The inner support 22, outer panel 24, and hinge base 26 may each have a unitary, one-piece construction. In other approaches, the inner support 22, outer panel 24, and hinge base 26 may be formed using blow molding or additive manufacturing.

(25) Regarding FIG. 2, the hinge base 26 includes an inner surface 32 that is mounted to a surface of the body 14 near the opening 34. The inner support 22 and outer panel 24 mounted thereto are shown in FIG. 2 in the closed position relative to the hinge base 26. The inner support 22 and outer panel 24 mounted thereto may pivot outward in direction 40 to the open position around the axis 30. The inner support 22 includes a gooseneck portion 42 forming a recess 44 that receives a portion of the body 14 near the opening 34 and provides clearance for the inner support 22 as the inner support 22 pivots from the closed position to the open position. The baggage door 20 further includes a striker 46 mounted to the inner support 22 that is configured to engage a latch of the body 14 by the opening 34. The engagement between the striker 46 and the latch maintains the inner support 22 and outer panel 24 in the closed position until the latch is released by the operator of the vehicle, such as by an actuator near the driver's seat. The striker 46 may be made of steel, as one example. Alternatively or additionally, the baggage door 20 may include a lock or other anti-theft device.

(26) The inner support 22 has a body 50 that includes the hinge portion 28, gooseneck portion 42, and an arm portion 52 extending away from the gooseneck portion 42 to an end portion 200. The body 50 includes one or more reinforcement members, such as ribs 60, 62, 64 and 66. The ribs 60, 62, 64, 66 are separated by recesses, such as channels 70, 72, 74. The ribs 60 are connected together at the end portion 200 by a raised connector portion 76. The ribs 60, 62, 64, 66 provide a crenulated cross-section of the inner support 22 which increases the rigidity of the inner support 22 throughout the inner support 22 including at the hinge portion 28. By improving the rigidity of the inner support 22, the connected inner support 22 and the hinge base 26 provide a rigid construct that resists loading in the downward direction 80 such as if an operator were to pull downward on the outer panel 24 when the baggage door 20 is opened.

(27) With reference to FIG. 3, the outer panel 24 includes an inner surface 90 having one or more mounts 92, such as upper mounts and lower mounts 94, 96 and side mounts 98, 100, for connecting the outer panel 24 to the inner support 22. In one embodiment, the upper and lower mounts 94, 96 have upper and lower walls 102, 104 and the inner support 22 has a skirt portion 106 that fits over the mounts 92 and extends along the upper and lower walls 102, 104. In this manner, the upper and lower mounts 94, 96 nest within the inner support 22 and provide a firm connection between the outer panel 24 and the inner support 22. The mounts 92 include one or more openings 108 that are aligned with one or more openings 110 of the inner support 22 when the outer panel 24 is mounted to the inner support 22. The baggage door 20 includes one or more fasteners, such as screws 112, 114, for connecting the inner support 22, the outer panel 24, and the striker 46. In one embodiment, the baggage door 20 includes fastener receivers, such as U-nuts 116, that are positioned on inner walls 118 of the mounts 92. The U-nuts 116 have threads that receive threaded shanks of the screws 112, 114. The screws 112 and/or 114 may be, for example, M6×25 mm screws with hex heads and captive washers and the U-nuts 116 are M6 U-nuts. In another approach, the inner support 22 and the outer panel 24 may be connected using a heat staking operation.

(28) Regarding FIGS. 2 and 3, the skirt portion 106 of the inner support 22 includes upper skirt portion 130, side skirt portion 132, and a lower skirt portion 134. The skirt portions 130, 132, 134 form a C-shape that mates with the generally C-shaped arrangement of the upper mount 94, side mount 98, and lower mount 96. This mating engagement forms a rigid construct of the outer panel 24 and inner support 22 that resists relative linear movement and relative turning therebetween.

(29) With reference to FIG. 3, the hinge portion 28 of the inner support 22 includes one or more knuckles 140 that are laced with one or more knuckles 142 of the hinge base 26. The knuckles 140 include through openings 144 and the knuckles 142 include through openings 146 that are aligned with the through openings 144 with the knuckles 140 are laced with the knuckles 142. The hinge pin 148 extends through the through openings 144, 146 of the laced knuckles 140, 142. The hinge pin 148 and the knuckles 140, 142 together define the pivot access 30 about which the inner support 22 and outer panel 24 mounted thereto may pivot. The hinge pin 148 may be made of a metal, such as hardened steel.

(30) With reference to FIG. 4, the inner support 22 has an outer surface 160 and a receptacle 162 extending outwardly therefrom with openings 164 for receiving fasteners to connect the receptacle 162 to the side mount 100. The inner support 22 further includes a peripheral wall portion 166 extending laterally from the ribs 60, 66. The peripheral wall portion 166 includes the openings 110 that receive the screws 112.

(31) The knuckles 140 of the inner support 22 include knuckles 170, 172, 174. The knuckles 170, 174 are substantially identical and near images of each other about a longitudinal center axis 176 (see FIG. 2) of the inner support 22. The knuckle 172 may be different than the knuckles 170, 174 to facilitate injection molding of the inner support 22. In one embodiment, the knuckle 172 includes a loop portion 178 that extends around the through opening 144 of the knuckle 172. Each of the knuckles 140 includes side wall portions 250, 252 that are in confronting relation with side wall portions 184, 186 (see FIG. 8) of the nearby knuckles 142.

(32) With reference to FIGS. 2 and 5, the inner support 22, hinge base 26, and outer panel 24 have respective lines of symmetry that permit the components of the baggage door 20 to be assembled in a first configuration for a driver's side baggage door and a second configuration for a passenger's side baggage door. More specifically, the outer panel 24 may be curved and inclined as shown in FIG. 16 to compliment the exterior of the vehicle body 14. The outer panel 24 is symmetric about an axis 175 (see FIG. 2) and may be rotated 180 degrees about the axis 175 to cover either the driver's side or the passenger's side baggage door. Likewise, the hinge base 26 and the inner support 22 are symmetrical about the longitudinal axis 126. The hinge base 26 and the inner support 22 may be rotated 180 degrees about the axis 176 to be installed at either the driver's side or the passenger's side of the vehicle body 14. Thus, the major components of the baggage door 20 have a first plane of symmetry (along axis 175) for the outer panel 24 and a second plane of symmetry (along axis 176) for the inner support 22 and hinge base 26. The two planes of symmetry permit the baggage door 20 to be installed on either the driver's side or the passenger's side of the vehicle body 14.

(33) The ribs 60, 62, 64, 66 extend longitudinally and are laterally offset from the knuckles 170, 172, 174 of the inner support 22. This configuration forms a generally U-shaped profile of the inner support 22 at the hinge portion 28 surrounding the knuckles 140 to increase the rigidity of the connection between the hinge base 26 and the inner support 22. More specifically, the rib 66 has a side wall portion 190, the rib 64 has a side wall portion 192, and the channel 74 includes an end wall portion 194. The side walls 190, 192 and end wall portion 194 extend down toward the knuckle 174 and form a rigid cross-sectional shape of the hinge portion 28. The ribs 60, 62, 64 form similar configurations at the knuckles 170, 172.

(34) The ribs 60, 62, 64, 66 extend from the knuckles 170, 172, 174 toward the end portion 200 of the inner support 22 and provide rigidity throughout the inner support 22. The inner support 22 further includes a striker compartment 202 that is recessed relative to the raised connection portion 76. The striker compartment 202 provides a surface 203 for mounting the striker 46.

(35) With reference to FIG. 6, the rib 60 of the inner support 22 includes a rib inner wall 210 that extends from the hinge portion 28 of the inner support 22 to the end portion 200. The rib inner wall 210 has a first thickness 212 at the hinge portion 28 and a thickness 216 at the end portion 200. The rib inner wall 210 may have a decreasing thickness from the hinge portion 28 to the end portion 200 such that the thickness 212 is greater than the thickness 216. The greater thickness 212 at the hinge portion 28 provides more material near the knuckles 140 and further increases the rigidity of the connection between the inner support 22 and the hinge base 26. The other ribs 62, 64, 66 have configurations similar to the rib 60.

(36) With reference to FIG. 7, the channel 70 of the inner support 22 includes an outer floor 220 having a thickness 222 at the hinge portion 28 and a thickness 224 at the end portion 200. The channel outer floor 220 extends away from the knuckle 170 toward the end portion 200 and decreases in thickness as the channel outer floor 220 extends through the gooseneck portion 42 and the arm portion 52 of the inner support 22. The thicker material of the channel outer floor 220 at the knuckle 170 increases the strength of the inner support 22.

(37) Regarding FIGS. 7 and 15, the hinge portion 28 of the inner support 22 includes webs 230 extending intermediate side wall portions 190, 192 of adjacent ribs 60, 62, 64, 66. The webs 230 further strengthen the hinge portion 28 of the inner support 22 and form a box-shaped section of the hinge portion 28 near the knuckles 140, such as near the knuckle 174.

(38) With reference to FIGS. 8 and 12, the knuckles 142 of the hinge base 26 include knuckles 240, 242, 244, 246 having the through openings 146 formed therein for receiving the hinge pin 148. When the knuckles 170, 172, 174 of the inner support 22 are laced with the knuckles 240, 242, 244, 246 of the hinge base 26, the knuckles 240, 242, 244, 246 have side wall portions 184, 186 that are in confronting relation with side wall portions 250, 252 of the adjacent knuckles 170, 172, 174. The confronting relation between the side wall portions of the laced knuckles 170, 172, 174 and 240, 242, 244, 246 transfers loading of the inner support 22 in either direction 254, 256 and maintains the outer panel 24 at the set vertical position thereof. The laced knuckles 170, 172, 174 and 240, 242, 244, 246 further resist a bending moment created at the connection between the inner support 22 and the hinge base 26 if a vertical, downward load is applied to the outer panel 24, such as if an operator pulls downwardly on the outer panel 24.

(39) Regarding FIG. 8, the ribs 60, 62, 64, 66 have inner wall portions 210 with thicknesses 260 that are substantially the same at the gooseneck portion 42. The thickness 260 at each rib 60, 62, 64, 66 is defined between an inner surface 257 and an outer surface 259 of the inner support 22. The thicknesses 260 increase as the ribs 60, 62, 64, 66 extend toward the knuckles 170, 172, 174 and decrease as the ribs 60, 62, 64, 66 extend toward the end portion 200.

(40) With reference to FIG. 9, the ribs 64, 62 have side wall portions 270, 272 and the channel 72 has an outer floor 274 extending therebetween. As the ribs 62, 64 and channel 72 extend from the gooseneck portion 42 toward the end portion 200, the ribs 62, 64 narrow near the compartment 162. Regarding FIG. 10, the compartment 162 includes side wall portions 280, 282 that are separated by a distance 284 and the side wall portions 270, 272 aft of the compartment 162 are separated by a distance 286 that is less than distance 284. The compartment 162 includes a floor portion 290 having the openings 164 that receive screws for connecting the compartment 162 to the side mount 100. The floor portion 290 provides a wide, flat surface to transfer loading from the side mount 100 to the inner support 122.

(41) With reference to FIG. 11, the ribs 60, 62, 64, 66 each have a thickness 300 near the end portion 200 that is less than the thickness 260 of the ribs 60, 62, 64, 66 at the gooseneck portion 42. The decreasing thickness of the ribs 60, 62, 64, 66 reduces the weight of the inner support 22.

(42) Turning to FIG. 12, the hinge base 26 includes a body 311 having the inner surface 32 for being positioned against a surface near the baggage door opening 34 and an outer surface 310 opposite the inner surface 310. The hinge base 26 includes pockets 320 with through openings 312, 314, 316, 318. The pockets 320 include end pockets 322, 323 and center pockets 324, 325 on opposite sides of an axis 326 of symmetry of the hinge base 26. The pockets 322, 324 are mirror images of the pockets 323, 325 about the axis 326. The pockets 320 provide reinforcement for the hinge base 26 about the through openings 312, 314, 316, 318 to resist crack propagation throughout the hinge base 26. Further, the hinge base 26 includes an outer wall or return flange 330 extending around a periphery of the hinge base 26 to provide further rigidity and resistance to crack propagation.

(43) Regarding FIG. 13, each pocket 322, 323, 324, 325 has a pocket perimeter wall 332 including straight portions 334, 336 that extend to the respective knuckle 240, 242, 244, 246. Each pocket 320 further includes a hub wall 338 extending about the associated through opening, e.g. through opening 314, and webs or radial walls, such as radial walls 340, extending outwardly from the hub wall 338 to the pocket perimeter wall 332. The radial walls 340 brace the hub wall 338 against forces acting on the hub wall 338 in radial directions such as directions 342, 344.

(44) For example, if the hinge base 26 is mounted as shown in FIG. 13 with the through opening 312 vertically above the through opening 318, the hinge base 26 may be subjected to a moment acting into the page in FIG. 13 when a load is applied in a downward direction 352 near the end portion 200 of the inner support 22, such as by an operator pulling downward on the outer panel 24 when the outer panel 24 is partially open. The load in direction 352 also causes reaction forces at the mounting bolts into and out of the page of FIG. 13.

(45) The load in direction 352 on the inner support 22 is transferred from the inner support 22 to the hinge base 26 via the laced knuckles 170, 172, 174 and 240, 242, 244, 246 and hinge pin 148. The body 311 of the hinge base 26 urges the pocket perimeter wall 332 of the pocket 322 in direction 344 which places some of the radial walls 340 of the pocket 322 in compression between the pocket perimeter wall 332 and the hub wall 338 of the pocket 322. The hub wall 338 presses in direction 344 against the fastener received in through opening 312.

(46) Conversely, the load in direction 352 on the inner support 22 causes the body 311 of the hinge base 26 to urge the perimeter wall 332 of the pocket 323 in direction 342. This places some of the radial walls 340 of the pocket 323 in tension between the perimeter wall 332 and the hub wall 338 of the pocket 323. The hub wall 338 presses in direction 342 against the fastener received in the through opening 318. The pockets 322, 323, 324, 325 thereby transfer loading from the inner support 22 to the fasteners securing the hinge base 26 to the body 14 of the truck 12. Further, the pocket perimeter wall 332, hub wall 338, and radial walls 340 of each pocket 322, 323, 324, 325 create a non-planar geometry of the hinge base 26 around the through openings 312, 314, 316, 318 that inhibits crack propagation through the hinge base 26.

(47) With reference to FIG. 14, the pockets 320 include cavities 360 formed between the pocket perimeter wall 332, hub wall 338, and a floor 362 of the pocket 320. The floor 362 is contiguous with a loop portion 364 of the knuckle 242 and cradles the hinge pin 148 when the hinge pin is received in the through opening 146 of the knuckle 242.

(48) Regarding FIG. 15, the hinge base 26 has a longitudinal axis 370 and an axis of symmetry 372. The symmetry of the hinge base 26 permits the hinge base 26 to be flipped to install the baggage door 20 on either the driver's side or the passenger's side of the vehicle body 20 as discussed above.

(49) Regarding FIGS. 17 and 18, a baggage door 400 is provided that is similar in many respects to the baggage door discussed above such that differences will be highlighted. The baggage door 400 includes an inner support 402, an outer panel 404, and a hinge base 406. The inner support 402 includes a body 408 having a hinge portion 410, a gooseneck portion 412, and an arm portion 414. The body 408 includes longitudinal ribs 420, 422, 424, 426 extending substantially the entire length of the inner support 402. The inner support 402 includes channels 430, 432, 434 separating the ribs 420, 422, 424, 426. The inner support 400 includes rib supports, such as bridging, connecting the ribs 420, 422, 424, 426. In one embodiment, the bridging includes cross-bridging 440 including intersecting struts 442, 444 configured to resist relative movement of the ribs 420, 422, 424, 426. The cross-bridging 440 adds resistance to bending (such as an operating grasping the outer panel 404 as he falls), relative longitudinal movement of the ribs 420, 422, 424, 426, and twisting of the ribs 420, 422, 424, 426.

(50) Regarding FIG. 19, the inner support 402 also includes braces 445 extending between outer side wall portions 450 of the ribs 420, 426 and to wall portions 452, 454 from which skirt portions 456, 458 of the inner support 402 depend therefrom. The braces 445 resist bending of the wall portions 452, 454 relative to the ribs 420, 426. The outer panel 404 includes mounts 502, 504 that may be secured using fasteners to the wall portions 452, 454 of the inner support 402. The braces 445 increase the rigidity of the construct of the inner support 402 and outer panel 404.

(51) Regarding FIG. 19, the cross-bridging 440 may extend through the gooseneck portion 412 into the hinge portion 410. The cross-bridging 440 may include larger struts 460, 462 with varying lengths, thicknesses, and curvatures to provide rigidity to the inner support 402 throughout the length of the inner support 402. The cross-bridging 440 and the struts 442, 444 interconnect side wall portions 450, 470 of adjacent ribs, such as ribs 420, 422. The struts 442, 444 may be upstanding from a floor portion 473 of the inner support 402 that extends between adjacent ribs 420, 422, 424, 426. The floor portion 743 and cross-bridging 440 create a rigid interconnection between the ribs 420, 422, 424, 426 while still permitting the inner support 402 to be have a unitary, one-piece construction, such as being formed by injection molding.

(52) Regarding FIGS. 19 and 20, the ribs 420, 422, 424, 426 also include internal rib supports, such as bridging. In one embodiment, the bridging includes cross-bridging 480 having struts 490, 492 extending between the side wall portions 450, 470. The struts 490, 492 intersect and resist relative movement of the side wall portions 450, 470 of each of the ribs 420, 422, 424, 426. Each rib 420, 422, 424, 426 includes an upper wall portion 493 connecting side wall portions 450, 470 as shown in FIG. 19. The struts 490, 492 depend from the upper wall portion 493 and provide a rigid cross-section of the ribs 420, 422, 424, 426 while permitting the inner support 402 to have a unitary, one-piece construction such as being formed by injection molding.

(53) Regarding FIG. 19, the cross-bridging 440 between the ribs 420, 422, 424, 426 and the cross-bridging 480 within the ribs 420, 422, 424, 426, in addition to the braces 445, forms a rigid plane 500 of the inner support 402. This rigid plane 500 increases the rigidity of the baggage door 400 while minimizing the material used to form the inner support 402. As shown in FIG. 19, the skirt portions 456, 458 of the inner support 402 extend along the mounts 502, 504 of the outer panel 404 and provide a rigid connection between the inner support 402 and the outer panel 404.
