~~TAILED DESCRI:?TTON OF THE PREF RRF EMBODIMENT
While the :i.nvention may be susceptible to embodiment in different forms, thESre is shown in the drawings, and herein will be described in detail, specific embodiments w:Lth the understanding that the present disclosure is to be considered am exemplification of the principles of the invention, and is not intended to limit the invention to that as illustrated and described herein.
Turning nom to the: drawings, a trailer 20, 20a constructed in accordance with the present invention is shown in FIGURE~~ 1 and 14. The trailer 20 of FIGURE 1 is shown connected to a tractor 21 by conventional means, sL.ch as a fifth wheel assembly. The trailer 20a of FIGURE 14 can likewise be connected to a tractor. The t-railer 20, 20a includes a body 22, 22a formed from a pair of rectangular sid.ewalls 24, 24a, a front wall 26, 26a, rear doors 28, 28a, a top panel or roof 30, 30a and a floor 32, 32a. The floor 32, 32a is supported by a conventional rear undercarriage assembly 34, 34a and has a landing gear 36, 36a secured thereunder. The top panel 30, 30a and an upper portion of the si.dewalls 24, 24a are secured to a top rail 38, 38a and the floor 32, 32a and lower portion of the sidewalls 24, 24a are secured to a bottom rail 40, 40a.
The top rai:1 38a, .as shown in FIGURE 14, is an L-ahaped member leaving a first flat portion 39a and a se~~ond flat portion 41a. The first portion 39a is perpendicular to the second portion 41a: The first portion 39a of 'the top rail 38a attaches to the top panel or roof 30a whi:Le the second portion 41a of the top rail 3Ba attaches to the sidewalls 24a. The bottom rail 40a, a.s shown in FIGtJRE 14, is of similar construction to the t~~p rail 38a and attaches to the floor 32a and the s:idewalls 24a in a similar manner as the top rail 38a at=taches to the roof 30a and the sidewalls 24a. The top and bottom rail: 38a, 40a maybe formed out of aluminum by an extrusion process.
Each sidewall 24, 24a includes a plurality of vertical upstanding composite side panels 42, 42a joined together by a novel joint configuration 44, 44a. Each composite side panel 42; 42a includes a plastic core member sandwiched between an inner thin metal skin and an outer thin metal skin and bonded thereto by-a suitable known adhesive or other like means. One advantage of the composite panel 42, 42a. used in the present invention is tr.at it can be coined or stepped down easily by applying pressure to the area to be coined or stepped down, whereas in the prior art aluminum sidewalls, the aluminum sidewall could not be easily coined.
The inner skin and the outer skin are preferably approximately 0.026 inches thick. The skins are preferably made ~~f aluminum; galvanized, full hardened steel, such as A:ISI Grade E full hard steel because of its cost effectiveness, or the like. Preferably, the outer skin is made of ASTM G90 galvanized steel and the inner skin is made of ASTM G60 galvanized steel.
Aluminum may be used, b,at it may be too soft for some r _ purposes and strength and punch resistance are sacrificed, however, aluminum is lightweight. Typically, each panel 42, ~62a is i=our feet in width, but can be longer or shorter depending on the application. At least two panels are jioined together by the novel joint configuration 49:, 44a t:o form the sidewall 24, 24a of the tz~ailer body 22, 22a.
Each core member i.s made of some type of compressible non.-metal material, preferably tr~.ermoplastic, such as polypropylene or high density polyethylene. These materials are relatively inexpensive as compared to aluminum found in prior trailer wall - ccnstructions. In addition, because a composite panel 42, 42a is used, the weight of the trailer construction is reduced over trailers having aluminum sidewalls.
Attention is now directed to the various embodiments -of the novel joint configuration 44, 44a used in forming the trailer sidewalls 24, 24a as shown in FIGURES 2-13, 15-16. A first embodiment of the joint configuration 144 is shown in FIGURE 2. .~ second embodiment of the joint configuration 24~~ is shown in FIGURE 3; a third em:~odiment of thE~ joint configuration 344 is shown in FIGURE 4 ; a fouri:h embodiment of the j oint configuration 44-~ is shown in 1?IGURES 5 and 6; a fifth embodiment of thcs joint configuration 544 is shown in FIGURE 7; a sixth embodiment of the joint configuration 644 is shown in FICJURES 8 and 9; a seventh embodiment of the joint configuration 746 is shown in FIGURE 11; an eighth em~~odiment of the: joint configuration 844 is shown in FIGURE 13; a ninth embodiment of the joint configuration 944 is shown in FIGURE 15; and a tenth embodiment of the joint configuration 1044 is shown in FIGURE 16. Like elements are denoted with like reference numerals with the first embodiment being in the one hundreds, the second embodiment being in the two hundreds, the third embodiment being in the three hundreds, the fourth embodiment being in the four hundreds, the fifth embodiment being in the five hundreds, the sixth embodiment being in the six hundreds, the seventh embodiment being in the seven hundreds, the eighth embodiment being in the eight hundreds, the ninth embodiment being in the nine hundreds and the tenth em~odiment being in the ten hundreds. As shown in the dr<~wings, only a portion of two joined panels 142a, 142b;
242a, 242b; 342a,, 342b; 442a, 442b; 542a, 542b; 642a, 64?b; 742a, 742b; 842a, 842b; 942a, 942b; 1042a, 1042b arES shown. It i~a to be understood that a plurality of panels may be used to form each sidewall 124, 224, 324, 426, 524, 624, 7~:4, 824, 924, 1024. In addition, the no'rel joint 144, 244, 344, 444, 544, 644, 744, 844, 944, 1064 is only shown between one end of the two panels 14~!a, 142b; 242a, 242b; 342a, 342b; 442a, 442b; 542a, 54a:b; 642a, 642b; 742a, 742b; 842a, 842b; 942a, 942b;
109:2a, 1042b. It is to be understood that a like joint is provided between each adjacent end of each panel used to form the trailer sidewall.
Directing attention to the first embodiment of the novel joint configuration 144 shown in FIGURE 2, first and second composite panels 142a, 142b are shown and are joined together by a logistics plate 152 on the inside of the trailer 20 which extends along the entire height of the panels 142a, 142b and by a splicing member 154 on the outside of the trailer 20 which extends along the entire height of the panels 142a, 142b. The ends 156a, 156b of the panels 142a, 142b are spaced apart from each other when joined by t:he logistics plate 152 and the splicing member 154 such 'that an air pocket 158 is formed between the logistics plate 152 and the splicing member 154.
Each end of the inner skins 148a, 148b of each panel 14.2a, 142b have <~n end section 160a, 160b (only one~of which is shown on each panel 142a, 142b) which is coined or stepped down with an intermediate section 161a, 161b of each panel 142a, 142b remaining planar. The outer skin 15-Oa, 150b of the panels 142a, 142b is not coined and remains planar. When the end section 160a,~160b of each inner skin :L48a, 148b is coined, the core member l4t;a, 146b is squeezed or compressed between the inner and outer skins 7_48a, 150a; 148b, 150b and the core member 146a, 146b may slightly extrude outwardly from the ends of the skins; 148a, 150a; 148b, 150b and into the air pocket 158 formed between the panels 142a, 142b.
The logistics plate 152 is a flat member having an inner surface and an outer surface and which has a .
plurality of spaced openings or slots 162 therethrough along an intermediate portion of the logistics plate 152.
The: slots 162 provide a means for which equipment can be engaged, for example by a clip or a hook, to the sidewall ~4, of the trailer 20. The logistics plate 152 is ~~referably forrr~ed from a heavier and stronger material than the material that is used for the skins 148a, 150a;
148b, 150b to provide the sidewall with strength and rigidity. When the logistics plate 152 is joined with the inner skins 148a, 148b of the panels 142a, 142b, the outer surface of the logistics plate 152 sits against the inner surfaces of the inner end sections 160a, 160b such that the inner .surface of the logistics plate 152 is flush with the .inner surfaces of the intermediate sections 161a, :161b of the inner skins 148a, 148b to provide a co-planar surface along the length of the s:idewall 24 in i=he interior of the trailer 20. Because the ends of the logistics plate 152 are flush with the intermediate seta ions :L6la, 161b of the inner skins-148a, ~1~~8b, snagging of cargo on the edges of the logistics p:Late 152 is substantially prevented. The logistics plate 152 bridge's the gap between the panels 142a, 142b such that the s7.ots 16::'align with the air pocket 158 so treat clips or hooks can'be engaged with the slots 162.
The splicing member 154, which is like a post, is attached to the outer surface of the outer skins 150a, l~~Ob and extends. to clear the top and bottom rails 38, 40 of the trailer 20. The splicing member 154 has flat end portions 164 which lie against the outer surfaces of the oL.ter skins 150a, 150b and an intermediate portion 166 wr.ich bulges outwardly from the end portions 164. When - -th.e splicing member 154 is joined with the outer surfaces of the outer skins 150a, 150b of the panels 142a, 142b, the inner surfa<:es of the end portions 164 lie against the planar outer. skins 150a, 150b and the intermediate portion 166 bulcres outwardly from the sidewall. The splicing member 154 bridges the gap formed between the p~inels 142a, 14~;b such that the bulging intermediate portion 166 aliens with the air pocket 158. Because the bulge is provided on the outside of the trailer 20, a smooth inner surface is provided within the trailer 20.
Tr.is allows for more width within the inside of the trailer 20 to load freight therein.
The logistics plate 152 and splicing member 154 are attached to the first and second panels 142a, 142b by suitable means, such as rivets 168, which extend through the logistics plate 152, the respective coined sections 160a, 160b of the panels 142a, 142b and the end portions 164 of the splicing member 154. The splicing member 154 seals the juncti~~n between the panels 142a, 142b on the exterior of the trailer 20 so as to seal the interior fr~~m moisture.
Attention i;a now directed to the second embodiment of the novel joint configuration 244 shown in FIGURE 3.
In this embodiment, first and second composite panels 24?a, 242b are joined together by a logistics plate 252 on the inside of the trailer 20 which extends along the ent=ire height of the panels 242a, 242b and by a splicing member 254 on the: outside of the trailer 20 which extends along .the entire height of the panels 242a, 242b. The ends 256a, 256b of the panels 242a, 242b are spaced apart from each other t:o provide a gap therebetween when joined b=,r,the logistic, plate 252 and the splicing member 254 such that an air pocket. 258 is formed between the logistics plate 252 and the splicing member 254.
Each end of: the outer skins 250,, 250b of each panel 2~62a, 242b have an end section 263,, 263b (only one of which is shown on each panel 242,, 242b) which is coined on stepped down with an intermediate section 265,, 265b of each panel 242,, 242b remaining planar. The inner skin 248,, 248b of the panels 242,, 242b is not coined ar..d remains planar. Wren the end section 263,, 263b of each outer skin 250,, 250b is coined, the core member 246,, 246b is squeezed or compressed between the skins 248,, 250,; 248b, 250b and the core member 246,, 246b may slightly extrude outwardly from the ends 256,, 256b of - 15 the panels 242,, 242b and into the air pocket 258.
The logistics plate 252 acts like a post and has end portions 270 which are flat and an intermediate portion 272 which bulges inwardly from the end portions 270. The bulging intermediate portion 272 has a plurality of spaced openings ~~r slots 274 therethrough. The slots 274 provide a means .for which equipment can be engaged, for example by a clip or a :hook, to the trailer sidewall.
Th~~ logistics plate 252 is preferably formed from a he<~vier and stronger material than the material that is usf~d for the skins 248,, 250,, 248b,.250b to provide the siciewall 24 with strength and rigidity. When the lo<~istics plate :?52 is .joined with the inner skins 248,, - -24tib of the pane=Ls 242,,, 242b, the outer surface of the end portions 270 sits against the inner surface of the inner skins 248a, 248b such that the intermediate portion 272 bulges to the inside of the trailer 20. The logistics plate 252 bridges the gap formed between the p,~nels 242a, 242b such that the bulging intermediate p~~rtion 272 which has the slots 274 therethrough aligns with the gap .
The splicing member 254 is flat and extends to clear the top and boti~om rails 38, 40 of the trailer 20. When the splicing.mernber is joined with the outer skins 250a, 2~~Ob of the panels 242x, 242b, the inner surface of the splicing member 254 sit=s against the coined end sections 2E>3a, 263b such that the outer surface of the splicing mE:mber 254 is flush with the outer surface of the -rEapective intex~cnediate: sections 265a, 265b of the outer skins 250a, 250b to provide a co-planar surface along the length of the -si.dewall 24 on the outside of the trailer 2C~. The splicing member 254 bridges the gap formed beaween the panels 242x, 242b.
The logistics plate 252 and the splicing member 254 are attached to the respective first and second panels 242a, 242b by suitable means, such as rivets 268, through th.e end portions 270 of the logistics plate 252, the respective coined sections 263a, 263b of the panels 242a, 242b and the splicing member 254. The splicing member 254 seals the junction between the panels 242a, 242b on the exterior of the trailer 20 so as to seal the interior from moisture..
Directing attention to the third embodiment of the novel joint configuration 344 shown in FIGURE 4, first and second composite panels 342a, 342b are joined together by a logistics plate 352 on the inside of the trailer 20 which extends along the entire height of the panels 342a, 34:2b and :by a splicing member 354 on the owtside of the trailer 20 which extends along the entire hfsight of the panels 342a, 342b. The ends 356a, 356b of the panels 342a,, 342b are spaced apart from each other to p==ovide a gap therebetween when joined by the logistics plate 352 and the splicing member 354 such that an air pocket 358 is formed between the logistics plate 352 and the splicing member 354.
Each end of: the inner skins 348a, 348b of each panel 34:2a, 342b has an end section 360a, 360b (only one of which is shown on each panel 342a, 342b) which is coined ox- stepped down with an intermediate section 361a, 361b of each panel 342a, 342b remaining planar. Each end of tree outer skins 350a, 350b of each panel 342a, 342b have ar.. end section 363a, 3E~3b (only one of which is shown on each panel 342a, 342b) which is coined or stepped down with an intermediate section 365a, 365b of each panel 342a, 342b remaining planar. When the end sections 360a, 363a; 360b, 363b are coined, the respective core members 346a, 346b are squeezed or compressed between the skins 348a, 348b; 350a, 350b and may. slightly extrude outwardly from the ends 356a, 356b of the panels 342a, 342b and into the air pocket 358.
The logistics plate 352 and the splicing member 354 - -are identical in construction to the second embodiment of the logistics,pl;~te 252 and the splicing member 254 shown a:nd described with respect to FIGURE 3. Therefore, the s:~ecifics of the construction of the logistics plate 352 a:zd the splicin<~ membe:r 354 are not repeated herein and instead, the re~Ference numerals are denoted with like numerals and area shown in the drawings .
When the logistics plate 354 is joined with the inner skins 348x, 348b of the panels 342a, 342b, the outer surfaces of the flat end portions 370 sit against the inner surfaces of t:he respective coined end sections 3E~Oa, 360b such that the inner surfaces of the end portions 370 are: flush with the inner surfaces of the intermediate secaions 361a, 361b of the inner skins 348a, 39:8b and the intermediate portion 372 of the logistics plate 352 bulges to the inside of the trailer 20. The er..ds 356a, 356b of the panels 342a, 342b are spaced apart from each other. Because the inner surfaces of the-end portions 370 are flush with the inner surfaces of the intermediate sections 361a, 361b of the skins 348a, 348b, snagging of cargo on the edges of the logistics plate 352 is substantially prevented. The logistics plate 352 bridges the gap formed between the panels 342a, 342b such that the bulging intermediate portion 372, which has the openings or slots 372 therein, aligns with the air pocket 358.
When the fl~~t splicing member 354 is joined with the outer skins 350a, 350b of the panels 342a, 342b, the inner surface of the splicing member 354 sits against the outer surfaces o:E the coined end sections 363x, 363b such th,~t the outer surface of the flat splicing member 354 is CA 02265405 1999-OS-03 .
f~_ush with the outer surfaces of the intermediate sections 365a, _o65b of the outer skins 350a, 350b to provide a co-planar surface along the length o.f the si.dewall 24 on t:he outside of the trailer 20. The splicing member 354 bridges the gap formed between the pG.nels 342a, 342b.
The logistics plate 352 and the splicing member 354 are attached to the respective first and second panels 342a, 342b by suitable means, such as rivets 368, through the end portions 370 of the logistics plate 352, the coined portions of the panels 342a, 342b and the splicing member 354. The splicing member 354 seals the junction between the panels 342a, 342b on the exterior of the trailer 20 so as to seal the interior from moisture.
Attention is now directed to the faurth embodiment of the novel joint configuration 444 shown in FIGURES 5 and 6. In this embodiment, first and second composite panels 442a, 442h are joined together by a logistics plate 452 on the inside of the trailer 20 which extends along the entire height of the panels 442a, 442b and the sp:Licing member provided in the previous embodiments has beE~n eliminated.
At one end of the :First panel 442a, as shown in FIC3URES 5 and 6, the outer skin 450a has a length that is substantially lomger than the length of the inner skin 44f3a. The ends of the inner and outer skins 448a, 450a frE:ely project beyond the end of the core member 446a so as to leave an open area between the inner and outer skins 448a, 450a at the ends of the first panel 442a. At t:ze other end o:E the panel 442a (not shown), the inner and outer skins 448a, 448b freely project beyond the end o:= the core mem~~er 446a the same distance so as to leave an open area between the inner and outer skins 448a, 450a.
At one end of the second panel 442b, the inner and outer skins 448b, 450b are of the same length and freely project beyond t:he end of the core member 446b the same amount so as to leave an open area between the inner and outer skins 448b, 450b. This structure is identical to the end of panel. 442a which is not shown. At the opposite end of. the second panel 442b, the construction i~; identical to the end of the first panel 442a shown in FIGURES 5 and 6.
The logistics plate 452 is formed by extruded or formed aluminum. The logistics plate 452 has flat end -portions 470 with an intermediate portion 472 that bulges inwardly therefrom. The end portions 470 are approximately the same thickness as the thickness of the core members 446a, 446b and each have a length which is approximately equal to the distance between the end of each inner skin 448a, 448b to the respective core members 446a, 446b. The bulging intermediate portion 472 has a thickness which is substantially less than the thickness of the end portions 470 and has a plurality of spaced openings or slots 474 along the length thereof.
To assemble the logistics plate 452 with the first w and second panels 442a, 442b,. the end portions 470 of the logistics plate 452 are inserted between the inner and outer skins 448x, 450a,; 448b, 450b of the first and second panels 4~62a, 442b such that the ends of the end portions 470 generally abut against the ends of the core mE~mbers 446a, 49:6b. The ends of the inner skins 448a, 4S:8b sit adjacent to the junction between the respective end portions 470 and the bulging intermediate portion 472 of the logistics plate 452. The outer skin 450a of the first panel 442x. extends behind the logistics plate 452 ar..d lies against the outer skin 450b of the second panel 442b. The outer skin 450a may lie against outer skin 450b on the inside thereof or the outside thereof. An air pocket 458 is formed between the bulging intermediate portion 472 of the logistics plate 452 and the outer skin 450a of the first panel 442a. The slots 472 align with the air pocket 458 so that clips, hooks or the like can be attached thereto for attaching equipment to the logistics plate 452. Rivets 468 are engaged through the respective inner skins 448a, 448b, the respective end portions 470. of .the. logis~tics..plate 452, the respective outer skins 450a, 450b and the extension of the outer skin 450a.
The extension of the first panel outer skin 450a eliminates the need for the separate splicing member as used in the firsi~, second and third embodiments. The ouver skin 450a :is very thin, however, and, as such, does nor provide as much reinforcement as the splicing member provides. The e:~tension of the first panel outer skin w -450a seals the junction between the panels 442a, 442b on tht~ exterior of t:he trailer 20 so as to seal the interior from moisture.
Directing attention to the fifth embodiment of the novel joint configuration 544 shown in FIGURE 7, this embodiment is the same as the joint configuration 444 shown in the fourth embodiment except that the flat end portions 570 of the logistics plate 552 are not the same thickness as the: core members 546a, 546b. Instead, the flat end portions 570 and the bulging intermediate portion 572 of the lagi.stics plate 552 are of a substantially uniform thickness.
To fill the space between the respective end portions 570 of the logistics plate 552 and the respective outer skins 550a, 550b, an insert 576 is provided in each such space. Each insert 576 is made of high density plastic or metal and completely fills the space between the outer skin 550a, 550b and the end portion 570 of the logistics plate 552. The rivets 568 are engaged through the respective inner skins 548a, _. _ 54&b, the respective end portions 570 of the logistics plate 552, the respective inserts 576 and the respective outer skins 550a, 550b. When the rivets 568 are inserted through the pane:Ls 542a, 542b, the insert 576 suJ~stantially prEwents compression of the panels 542a, 54?b, which can occur during the insertion of a rivet be<~ause the core member 546a, 546b is made of a compressible material.
Alternative:Ly, the logistics plate 552 could be - -att:ached to the ~'.nner surface of the inner skins 548a, S48b with the respective inserts 576 completely filling t:he space between the skins 548a, 550a; 548b, 550b. In addition, the logistics plate 552 could be attached to the inner surface of,t:he inner skins 548a, 548b, the insert 576 eliminated, and the core member 546a, 546b u:~ed to completely fil:L the space between the skins 548a, 550a; 548a, 550x.
Directing attention to the sixth embodiment of the novel joint configuration 644 shown in FIGURES 8 and 9, first and second composite panels 642a, 642b are joined together by a logistics plate 652 on the inside of the trailer 20 which extends along the entire height of the p~.nels 642a, 642b and, like the fourth and fifth embodiments, the, splicing member provided in the previous embodiments has been eliminated.
At each end. of the: first panel 642a, the -outer skin 650a has a length that is substantially longer than the length of the inner skin 648a. The ends of the inner and outer skins 648a, 650a freely project beyond the end of the core member 646a so as to leave an open area between the inner and outer skins 648a, 650a at each end of the first panel 642a.
The second :panel 642b is similarly constructed to the first panel 642a. At each end of the second panel 642b, the outer ;skin 650b has a length that is substantially longer than the length of the inner skin 643b. The ends c~f the inner and outer skins 648b, 650b freely project beyond t:he end of the core member 646b so as to leave an o~~en area between the inner and outer skins 648b, 650b at each end of the second panel 642b.

The logistics plate 652 is identical in construction t« that describE~d with respect to the fourth embodiment.
Tlzus, a repetit:eon of the construction of the logistics p_Late 652 is not. repeated herein.
To assembles the logistics plate 652 with the first and second pane7_s 642a,, 642b, the flat end portions 670 of: the logistic: plate 652 are inserted between the inner and outer skins 648a, 650a; 648b, 650b of the first and second panels 69:2a, 642b such that the ends of the end portions 670 ger.~erally abut against the ends of the core mE:mbers 646a, 646b. The ends of the inner skins 648a, 69:8b sit adjacent to tree junction between the respective er.:d portions 670 and the bulging intermediate portion 672 of the logistics plate 652. The outer skin 650b of the second panel 642b extends behind the logistics plate 652 anal lays against the outer skin 650a of the first panel 642a. The outer skin 650a of the first panel 642a extends behind the logistics plate 652 and lies against the outer skin 650b of the second panel 642b. The outer _ skin 650a may lie against outer skin 650b on the inside or the outside of outer skin 650b. An air pocket 658 is formed between t:he bulging intermediate portion 672 of the logistics plate 652 and the outer skin 650a of the first panel 642a. The openings or slots 672 align with the air pocket 6:58 so that clips or the like can be attached thereto for attaching equipment to the logistics plate 652. Rives=s 668 .are engaged through the respective - -in:ner skins 648a, 648b, the respective end portions 670 of the logistics plate 652 and the respective outer skins 650a, 650b and the extensions of the outer skins 650a, 650b.
Because the outer skin 650a of the first panel 642a overlays the outer skin 65ob of the second panel 642b, a bend 678 is provided in the outer skin 6SOa of the first panel 642a so that the outer skins 650a, 6SOb lie against each other. This forms a double thickness behind the intermediate portion 672 of the logistics plate 652 to i provide more strength and rigidity than when a single thickness is used, such as that shown in the fourth and fifth embodiments. The extension of the outer skins 650a, 650b of the first and second panels 642a, 642b eliminates the need for the separate splicing member as shown in the previous embodiments. If desired, inserts, like those provided in the fifth embodiment, may be provided. The extensions of the outer skins 650a, 650b seal the junction between the panels 642a, 642b on the exterior of the trailer 20 so as to seal the interior from moisture. _ In the fourth, fifth and sixth embodiments of the novel composite joint configurations 444, 544, 644, the rivets 468, 568, 668 are engaged,by using the method and apparatus disclosed in co-pending United States Patent Application Szrial No. 08/620,999, entitled "Method of Punching A Composite Plate", which is commonly owned by the assignee herein. If desired, holes can be provided through the logistic panel 452, 552, 652 and the panels 442a, 442b; 542a, 542b; 642a, 642b.

Attention :is now directed to the seventh embodiment o:F the novel joint con:~iguration 744, shown in FIGURE 11, which has first and second composite panels 742a, 742b.
One of the panels 742b is shown in FIGURE 10. It is to bE: understood treat the other panels used to construct the trailer sidewal7. are identical in construction. At one end of the panel. 742b, as shown in FIGURE 10, the inner and outer skins 748b, 750b are longer than its associated cc>re member 746x> so as to freely project beyond the end of the core member 746b. At the opposite end of the panel 742b, the inner and outer skins 748b, 750b are stepped down or coined so as to provide an end portion 780b which has a thickness that is less than the thickness of the remainder of the panel 742b. The edge of the core member 746b is generally flush with the end of the coined end portion 780b of the panel 742b, however, when the skins 748b, 750b are coined, some core material may extrude outwardly therefrom.
As. shown- in.. FIGURE...I..l . ta. connect..the. panels ..742a._-742b together to form a sidewall 24 of the trailer 20, the coined end p~~rtion 780b of one panel 742b is inserted between the freely projecting inner and outer skins 748a,.
75~a of the adjacent panel 742a. When interconnected to~~ether, the outer surface of the inner skin 748b of panel 742b lies <~gainst the inner surface of the inner skin 748a of panE:l 742a and the outer surface of the outer skin 750b of panel 742b lies against the inner su~:-face of the outer skin 750a of panel 742a. When the panels 742a, 742b are joined together, because of the ;- , coined end portion 780b, the inner surfaces and outer surfaces of the panels 742a, 742b are smooth and flush along the length. thereof on the inside and outside of the trailer 20. An insert, like that disclosed in the fifth embodiment, may replace the core material between the skins in the coined end. portion 780b, if desired. Rivets 768 are engaged through. the freely projecting ends of the inner and outer skins 748a, 7Oa and the coined end portion 780b.
Attention is now directed to the eighth embodiment of the novel joint configuration 844, shown in FIGURE 13, which has first .and second composite panels 842a, 842b.
One of the panels 842a is shown in FIGURE 12. It is to be understood that the other panels used to construct the trailer sidewall 24 are identical in construction. At each end of the ~~anel 842b, as shown in FIGURE 12, the inner and outer ;skins 848b, 850b are longer than its associated core member ~946b so as to freely project beyond the ends of the core member 846b. The panel 842b ta~~ers from one E:nd to the other end such that the diatance D1 between the inner and outer skins 848b, 850b at one end is greater than the distance D2 between the inner and outer .skins 848b, 850b at the other end. Thus, thE: core member F346b tapers from one end of the panel 8.4:>.b to the other end of the panel 842b .
As shown in this embodiment, an insert 876, like the insert 576 in the; fifth embodiment, is provided between - -thE: freely projecaing skins 848b, 850b at the end of the panel 842b which has the lesser thickness. The insert 8?6 completely fills the space between.the inner and outer skins 8~48b, 850b and is made of high density plastic, metal or the like. When the rivets 868 are inserted through the panels 842a, 842b, the.insert 876 substantially prevents compression of the panels 842a, 842b, which can occur during the insertion of a rivet because the core member 846a, 846b is made of a compressible material. Alternatively, the insert 876 could be eliminated and the core member 846b extended to fill the space.
To connect the panels together to form a sidewall 24 the trailer 20, the smaller end of one panel 842b is inserted into the larger end of the adjacent panel 842a.
When interconnected together, the outer surface of the I5 inner skin 848b of panel 842b lies against the inner surface of the inner skin 848a of panel 842a and the outer surface of outer skin 850b of panel 842b lies against the inner surface of the outer skin 850a of panel 842x_. .
In the seventh and eighth embodiments of the novel joint configuration 744, 844, each rivet 768, 868 is engaged with the panels by using the method and apparatus disclosed in co-pending United States Patent Application Serial No. 08/620,999. During this punching process, the core material may extrude and fill any gaps between the end of the panel and the core member of the other panel. If desired, holes can be provided through the . .
skins of the one panel and the reduced portion of the i.
other panel through which the, rivets are engaged.
Directing attention to the ninth embodiment of the novel joint configuration 944 shown in FIGURE 15, this embodiment is the same as the joint configuration 144 shown in the first embodiment except that the construction of the spl.icing.member 954 is different. It i:; to be understood that the splicing member 954 described with respect to this embodiment can be used on ar..y of the embodiments in which a splicing member is provided, e.g., FIGURE 5.
The splicing member 954, which is like a post, is attached to the outer surface of the outer skins 950a, 950b and is mounted under and extends between the top and bottom rails 38a, 40a of the trailer 20a. The splicing member has a flat top portion 970, a flat bottom portion 972 and flat side-portions 974 which lie against the outer surfaces of the outer skins 950a, 950b, and an intermediate portion 966 which bulges outwardly from the top, bottom and side portions 970, 972, 974. When the splicing member 954 is joined with the outer surfaces of th~~ outer skins :950a, 9:50b of the panels 942a, 942b, the inner surfaces o:E the side portions 974 lie against the planar outer skins 950a, 950b and the intermediate portion 966 bulgEa outwardly from the sidewall. The bulging intermed:Late portion 966 of the splicing member 95~~ bridges the <~ir pocket 958 formed between the panels 942a, 942b and a_Ligns with the air pocket 958. The - -bu:Lging intermed:Late portion 966 provides for more space within the air pocket 958 to allow for the attachment of __ mt=tubers, such a:~ clip or hooks, to the slots 962 of the logistics plate member 952. Because the bulge is p~~ovided on the outside of the trailer 20a, a smooth inner surface is provided within the trailer 20a. This a_lows for more width within the inside of the trailer 20a to load freight therein.
The flat top portion 970 and the flat bottom portion 9','2 of the splicing member 954 facilitate connection of the panels 942a, 942b t:o the top and bottom rails 38a, 40a of the trailer 20a. In order to connect the si.dewalls 24a to the roof 30a, the roof 30a is laid on top of the edges of the sidewalls 24a. Each top rail 38a is connected by seating' the first portion 39a against the rcof 30a and the second. portion 41a against the respective sidewalls 24a. The second portion 41a of each top rail 38a sits over the flat top portion 970 of each splicing member 954 provided along the length of the respective sidewalls 24a. Each bottom rail 40a connects the floor 32a and the respective sidewalls 24a in the same manner as each top rail 38a connects the roof 30a and the respective sidewalls 24a. The flat top portions 970 and the flat bottom portions 972 facilitate in the connection of the panels 942a, 942b to the top and bottom rails 38a, 40a o:E the trailer 20a because they allow the rails 38a, 40a, which have flat second portions 41a, to easily be positioned against the splicing member 954. If th~=_ splicing members 954 did not have the flat top and bortom portions 170, 972, but rather have the bulging in~~ermediate portion 966 extending the entire height of each splicing member 954, the rails 38a, 40a would have to be formed to include bulges to fit over the bulging intermediate portion 966 of each splicing member 954.
Thus, the use of the flat top and bottom portions 970, 972 on the splicing member 954 allows for a much easier connection between the splicing member 954 than if the flat top and bottom portions 970, 972 were not a part of th.e splicing member 954.
The logistics plate 952 and the splicing member 954 are attached to the first and second panels 942a, 942b by suitable means, such as rivets 968, which extend through the logistics plate 952, the respective coined sections 960a, 960b of the panels 942a, 942b, the respective core members 946a, 946b, the respective outer skins 950a, 950b, and the respective side portions 974 of the -- splicing member :954. T:he splicing member 954 seals the junction between the panels 942a, 942b on the exterior of th~~ trailer 20a ;ao as to seal the interior from moisture.
Moreover, becauscs the flat top and bottom portions 970, 97:z are seated under tha_ top and bottom rails 38a, 40a, moisture does not: penetrate into the interior of the trailer 20a and cause damage to the freight of the tr<~iler 20a or to the trailer 20a itself.
In the first:, second, third and ninth embodiments of the, novel composite joint constructions 144, 244, 344, 94~~, to engage the rivets 168, 268, 368, 968 with the logistics plate 7.52, 252, 352, 952 the splicing member - -15~6, 254, 354, 954 and the respective first and second panels 142a, 142b; 242a,, 242b; 342a, 342b; 942a, 942b each rivet 168, 268, 368, 968 is engaged by using the method and apparatus disclosed in co-pending United Stsates Patent Applicat9_on Serial No. 08/620,999, which disclosure has x>een incorporated by reference. Coining tree ends of the panels 142a, 142b; 242a, 242b; 342a, 39:2b; 942a,,942b as described herein, condenses the plastic core member 146a, 146b; 246a, 246b; 346a, 346b;
946a, 946b sufficiently to support clamping force or pressure from the rivets 168, 268, 368, 968 without subsequent loosening. If desired, holes can be provided through the logistic panel 152, 252, 352, 952 and the splicing member 154, 254, 354, 954 through which the rivets 168, 268, 368, 968 are engaged.
In addition, in the first, second, third and ninth embodiments of t:he composite joint configurations 144, 244, 344, 944, it is envisioned that an insert, as discussed herein with respect to the fifth embodiment sh~~wn in FIGURE '7, can be provided in the construction of these embodiment:a of the trailer sidewalls.
Attention i:a now directed to the tenth embodiment of tht~ novel joint configuration 1044 shown in FIGURE 16.
In this embodiment, first and second composite panels 10~~2a, 1042b are joined together by a logistics plate 10x2 on the inside of the trailer 20 which extends along thE: entire height: of the panels 1042a, 1042b and the sp=.icing member ~>rovided in the first, second, third and ninth embodiment~~ has been eliminated. - -At one end of the first panel 1042a, as shown in FIGURE 16, the outer skin 1050a has a length that is_ r~
substantially l~~nger than the length of the inner skin 1048x. The end of the outer skin 1050a freely projects beyond the end c~f the core member 1046a and the inner skin 1048x. At the other end of the panel 1042a (not sZOwn), the innE~r skin 1048x, the outer skin 1050a and tJze core member 1046a all extend the same length in an identical structure to the end of the second panel 1042b shown in FIGURE 16.
At one end of the second panel 1042b, as shown irl F::GURE 16, the inner skin 1048b, the outer skin 1050b and the core member 1046b all extend the same length.

Th.e remainder of the inner skins 1048x, 1048b of the panels 1042x, 1042b remain planar. When the groove 1076x, 1076b is formed in the end section 1074x, 1074b of each inner skin 1048x, 1048b, the core member 1046x, 1046b is squeezed or compressed between the inner and outer skins 1048;x, 1050x; 1048b, 1050b and the core member 1046x, 10~46b may slightly extrude outwardly from the ends of the skins 1048x, 1050x; 1048b, 1050b and into - -the air pocket 1058 formed between the panels 1042x, 1042b. The groo~Tes 1076x, 1076b may be formed by coining.
The logistics plate 1052 acts like a post and is a member having a flat intermediate portion 1078 with o-~posite edges :L080a, :L080b which are rolled. A
p:Lurality of sp<~ced openings or slots 1062 are provided tJzrough the flat. intermediate portion 1078 of the logistics plate 1052. The slots 1062 provide a means for which equipment can be engaged, for example by a clip or a hook, to the .aidewalls 24 of the trailer 20. The logistics plate 1052 is preferably formed from a heavier and stronger material than the material that is used for t)'ie skins 1048a, 1050a; 1048b, 1050b to provide the si.dewall with strength and rigidity.
When the lagistics~ plate 1052 is joined with the ir.~ner skins 1048a, 1048b of the panels 1042a, 1042b, the rolled edges 1080a, 1080b of the logistics plate 1052 sit within the respective grooves 1076a, 1076b in the end sections 1074a, 1074b, and the flat intermediate portion 1078 spans the air pocket 1058 such that the slots 1062 align with the air pocket 1058 so that clips or hooks can be engaged with the slots 1062. The rolled edges 1080a, 1080b, when seated in the grooves 1076a, 1076b, provide a smooth transition from the logistics plate 1052 to the inner skins 1048~a, 1048:b.to substantially prevent snagging of cargo on the edges of the logistics plate 1052. Rivets 1068 are engaged through the ends of the lo~~istics plate :L052, tike respective inner skins 1048a, - -10~8b, the respective core members 1046a, 1046b and the re;~pective outer skins :L050a, 1050b.

The extension of t:he first panel outer skin 1050a e7.iminates the need for the separate splicing member as u~>ed in the first, second, third and ninth embodiments described herein.. The outer skin 1050a is very thin, however, and, as. such, does not provide as much reinforcement as the splicing member provides. The exaension of the first panel outer skin 1050a seals the junction between the panels 1042a, 1042b on the exterior of the trailer 20~ so as to seal the interior of the trailer 20 from moisture.
While preferred embodiments of the present invention are shown and described, it is envisioned that those skilled in the art may devise various modifications of the present invention without departing from the spirit and scope of the appended claims. For example, in any of - the embodiments which uses a logistics plate, the logistics plate may be flat or bulge inwardly. Also, in an-y of the embodiments which uses a splicing member, the - splicing member may be :flat or bulge outwardly and may ha-Ue the flat top and bottom portions if a bulge is pr~wided. An insert could be provided in any of the embodiments or e:Liminated in the embodiments where it is shown.
