Composite joint configuration
Abstract
A sidewall of a trailer is formed from at least two composite
panels joined together by a novel joining configuration. Each panel
is formed from inner and outer thin metal skins and a plastic core
sandwiched between the skins. In several embodiments, at least one
of the skins has at least one end coined to as to compress the core
between the skins to define a coined end section. A logistics plate
and a splicing member are used to join the panels together and are
secured thereto by rivets. The logistics plate and/or the splicing
member may sit against the coined end sections. The splicing member
may have flat top and bottom portions to facilitate in the
attachment of the panels to the top and bottom rails of the
trailer. In other embodiments, a logistics plate is secured by
rivets to the panels for joining them together. The splicing member
is eliminated and instead, the outer skin of at least one panel is
extended to lie behind the logistics plate. In yet another
embodiment, the inner skin may have rolled or formed grooves to
provide a smooth transition from a logistics plate having rolled
edges. An insert may be used between the skins where the rivets are
inserted in any of the embodiments to substantially prevent
compression of the panels.

Description
[0001] This application is a Continuation-in-Part of Ser. No.
08/712,770, entitled "Composite Joint Configuration" and filed Sep.
12, 1996.
BACKGROUND OF THE INVENTION
[0002] This invention is generally directed to a novel sidewall for
a trailer body. More particularly, the invention relates to joined
composite panels for trailer bodies, wherein each composite panel
includes a plastic core member sandwiched between thin metal skins
and joined together by novel joints.
[0003] Trailers of the general type disclosed herein include a
variety of types of sidewalls. A typical well-known construction is
a panel-type trailer which includes aluminum side posts. Generally,
it is desirable to have a relatively thin trailer sidewall so that
the total inside dimensions of the trailer body can be increased to
carry the optimum amount of cargo. In addition, it is desirable to
have a trailer sidewall which is lightweight.
OBJECTS AND SUMMARY OF THE INVENTION
[0004] A general object of the present invention is to provide a
novel joint configuration for joining a pair of composite panels
together in a trailer sidewall, wherein a plurality of such joined
panels may be used to form the trailer sidewall.
[0005] An object of the present invention is to provide a novel
sidewall for use in a trailer body, which sidewall is simple in
design and economical to manufacture while at the same time
providing maximum interior space in the trailer body.
[0006] Another object of the present invention is to provide a
novel sidewall having a plurality of joined composite panels,
wherein each composite panel includes a plastic core member
sandwiched between thin metal skins.
[0007] A further object of the present invention is to provide a
novel sidewall for use in a trailer body, which sidewall is easily
attached to the roof and the floor of the trailer body.
[0008] These and other objects and features of the present
invention will become more apparent from a reading of the following
descriptions.
[0009] Briefly, and in accordance with the foregoing, the present
invention discloses a sidewall of a trailer which is formed from at
least two composite panels joined together by a novel joining
configuration. Each panel is formed from inner and outer thin metal
skins and a plastic core sandwiched between the skins.
[0010] In several embodiments, at least one of the skins has at
least one end coined to as to compress the core between the skins
to define a coined end section. A logistics plate and a splicing
member are used to join the panels together and are secured thereto
by rivets. The logistics plate and/or the splicing member sit
against the coined end sections. The splicing member may have flat
top and bottom portions to facilitate in the attachment of the
panels to the top and bottom rails of the trailer.
[0011] In other embodiments, a logistics plate member is secured by
rivets to the panels for joining them together. The splicing member
is eliminated and instead, the outer skin of at least one panel is
extended to lie behind the logistics plate.
[0012] In another embodiment, the inner skin may have rolled or
formed grooves to provide a smooth transition from a logistics
plate having rolled edges.
[0013] In yet other embodiments, one end of each panel has a
thickness which is less than the other end of the panel. The skins
at the greater thickness end of the panel freely project beyond an
end of the core member. The lesser thickness end is inserted
between the skins of the other panel at the greater thickness end
and secured thereto by rivets. To form the lesser thickness, the
end of the panel may be coined or the panel may taper from one end
to the other end. An insert member, made of hard plastic or metal,
may be used between the skins where the rivet is inserted in any of
the embodiments to substantially prevent compression of the
panels.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0031] While the invention may be susceptible to embodiment in
different forms, there is shown in the drawings, and herein will be
described in detail, specific embodiments with the understanding
that the present disclosure is to be considered an exemplification
of the principles of the invention, and is not intended to limit
the invention to that as illustrated and described herein.
[0032] Turning now to the drawings, a trailer 20, 20a constructed
in accordance with the present invention is shown in FIGS. 1 and
14. The trailer 20 of FIG. 1 is shown connected to a tractor 21 by
conventional means, such as a fifth wheel assembly. The trailer 20a
of FIG. 14 can likewise be connected to a tractor. The trailer 20,
20a includes a body 22, 22a formed from a pair of rectangular
sidewalls 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 sidewalls 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.
[0033] The top rail 38a, as shown in FIG. 14, is an L-shaped member
having a first flat portion 39a and a second 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 while the second portion 41a of the top rail 38a attaches
to the sidewalls 24a. The bottom rail 40a, as shown in FIG. 14, is
of similar construction to the top rail 38a and attaches to the
floor 32a and the sidewalls 24a in a similar manner as the top rail
38a attaches to the roof 30a and the sidewalls 24a. The top and
bottom rails 38a, 40a maybe formed out of aluminum by an extrusion
process.
[0034] 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 that 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.
[0035] The inner skin and the outer skin are preferably
approximately 0.026 inches thick. The skins are preferably made of
aluminum; galvanized, full hardened steel, such as AISI 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, but it may be too soft for some purposes and strength and
punch resistance are sacrificed, however, aluminum is lightweight.
Typically, each panel 42, 42a is four feet in width, but can be
longer or shorter depending on the application. At least two panels
are joined together by the novel joint configuration 44, 44a to
form the sidewall 24, 24a of the trailer body 22, 22a.
[0036] Each core member is made of some type of compressible
non-metal material, preferably thermoplastic, such as polypropylene
or high density polyethylene. These materials are relatively
inexpensive as compared to aluminum found in prior trailer wall
constructions. In addition, because a composite panel 42, 42a is
used, the weight of the trailer construction is reduced over
trailers having aluminum sidewalls.
[0037] 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 FIGS. 2-13, 15-16. A first embodiment
of the joint configuration 144 is shown in FIG. 2. A second
embodiment of the joint configuration 244 is shown in FIG. 3; a
third embodiment of the joint configuration 344 is shown in FIG. 4;
a fourth embodiment of the joint configuration 444 is shown in
FIGS. 5 and 6; a fifth embodiment of the joint configuration 544 is
shown in FIG. 7; a sixth embodiment of the joint configuration 644
is shown in FIGS. 8 and 9; a seventh embodiment of the joint
configuration 744 is shown in FIG. 11; an eighth embodiment of the
joint configuration 844 is shown in FIG. 13; a ninth embodiment of
the joint configuration 944 is shown in FIG. 15; and a tenth
embodiment of the joint configuration 1044 is shown in FIG. 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
embodiment being in the ten hundreds. As shown in the drawings,
only a portion of two joined panels 142a, 142b; 242a, 242b; 342a,
342b; 442a, 442b; 542a, 542b; 642a, 642b; 742a, 742b; 842a, 842b;
942a, 942b; 1042a, 1042b are shown. It is to be understood that a
plurality of panels may be used to form each sidewall 124, 224,
324, 424, 524, 624, 724, 824, 924, 1024. In addition, the novel
joint 144, 244, 344, 444, 544, 644, 744, 844, 944, 1044 is only
shown between one end of the two panels 142a, 142b; 242a, 242b;
342a, 342b; 442a, 442b; 542a, 542b; 642a, 642b; 742a, 742b; 842a,
842b; 942a, 942b; 1042a, 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.
[0038] Directing attention to the first embodiment of the novel
joint configuration 144 shown in FIG. 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 the
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.
[0039] Each end of the inner skins 148a, 148b of each panel 142a,
142b have an 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 150a, 150b of the panels 142a, 142b is not
coined and remains planar. When the end section 160a, 160b of each
inner skin 148a, 148b is coined, the core member 146a, 146b is
squeezed or compressed between the inner and outer skins 148a,
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.
[0040] 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 24 of the trailer 20. The logistics plate 152 is
preferably formed 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 sidewall 24 in the interior of the trailer 20.
Because the ends of the logistics plate 152 are flush with the
intermediate sections 161a, 161b of the inner skins 148a, 148b,
snagging of cargo on the edges of the logistics plate 152 is
substantially prevented. The logistics plate 152 bridges the gap
between the panels 142a, 142b such that the slots 162 align with
the air pocket 158 so that clips or hooks can be engaged with the
slots 162.
[0041] The splicing member 154, which is like a post, is attached
to the outer surface of the outer skins 150a, 150b 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 outer skins 150a, 150b and an intermediate
portion 166 which bulges outwardly from the end portions 164. When
the splicing member 154 is joined with the outer surfaces of the
outer skins 150a, 150b of the panels 142a, 142b, the inner surfaces
of the end portions 164 lie against the planar outer skins 150a,
150b and the intermediate portion 166 bulges outwardly from the
sidewall. The splicing member 154 bridges the gap formed between
the panels 142a, 142b such that the bulging intermediate portion
166 aligns 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. This allows for more width within
the inside of the trailer 20 to load freight-therein.
[0042] 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 junction between the panels 142a, 142b on the
exterior of the trailer 20 so as to seal the interior from
moisture.
[0043] Attention is now directed to the second embodiment of the
novel joint configuration 244 shown in FIG. 3. In this embodiment,
first and second composite panels 242a, 242b are joined together by
a logistics plate 252 on the inside of the trailer 20 which extends
along the entire 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 to provide a gap
therebetween when joined by the logistics 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.
[0044] Each end of the outer skins 250a, 250b of each panel 242a,
242b have an end section 263a, 263b (only one of which is shown on
each panel 242a, 242b) which is coined or stepped down with an
intermediate section 265a, 265b of each panel 242a, 242b remaining
planar. The inner skin 248a, 248b of the panels 242a, 242b is not
coined and remains planar. When the end section 263a, 263b of each
outer skin 250a, 250b is coined, the core member 246a, 246b is
squeezed or compressed between the skins 248a, 250a; 248b, 250b and
the core member 246a, 246b may slightly extrude outwardly from the
ends 256a, 256b of the panels 242a, 242b and into the air pocket
258.
[0045] 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 or 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. The logistics plate 252 is preferably formed from a
heavier and stronger material than the material that is used for
the skins 248a, 250a, 248b, 250b to provide the sidewall 24 with
strength and rigidity. When the logistics plate 252 is joined with
the inner skins 248a, 248b of the panels 242a, 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 panels 242a, 242b such that the
bulging intermediate portion 272 which has the slots 274
therethrough aligns with the gap.
[0046] The splicing member 254 is flat and extends to clear the top
and bottom rails 38, 40 of the trailer 20. When the splicing member
is joined with the outer skins 250a, 250b of the panels 242a, 242b,
the inner surface of the splicing member 254 sits against the
coined end sections 263a, 263b such that the outer surface of the
splicing member 254 is flush with the outer surface of the
respective intermediate sections 265a, 265b of the outer skins
250a, 250b to provide a co-planar surface along the length of the
sidewall 24 on the outside of the trailer 20. The splicing member
254 bridges the gap formed between the panels 242a, 242b.
[0047] 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 the 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.
[0048] Directing attention to the third embodiment of the novel
joint configuration 344 shown in FIG. 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, 342b and by a splicing member 354 on the
outside of the trailer 20 which extends along the entire height of
the panels 342a, 342b. The ends 356a, 356b of the panels 342a, 342b
are spaced apart from each other to provide 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.
[0049] Each end of the inner skins 348a, 348b of each panel 342a,
342b has an end section 360a, 360b (only one of which is shown on
each panel 342a, 342b) which is coined or stepped down with an
intermediate section 361a, 361b of each panel 342a, 342b remaining
planar. Each end of the outer skins 350a, 350b of each panel 342a,
342b have an end section 363a, 363b (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.
[0050] The logistics plate 352 and the splicing member 354 are
identical in construction to the second embodiment of the logistics
plate 252 and the splicing member 254 shown and described with
respect to FIG. 3. Therefore, the specifics of the construction of
the logistics plate 352 and the splicing member 354 are not
repeated herein and instead, the reference numerals are denoted
with like numerals and are shown in the drawings.
[0051] When the logistics plate 354 is joined with the inner skins
348a, 348b of the panels 342a, 342b, the outer surfaces of the flat
end portions 370 sit against the inner surfaces of the respective
coined end sections 360a, 360b such that the inner surfaces of the
end portions 370 are flush with the inner surfaces of the
intermediate sections 361a, 361b of the inner skins 348a, 348b and
the intermediate portion 372 of the logistics plate 352 bulges to
the inside of the trailer 20. The ends 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.
[0052] When the flat 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 of the coined
end sections 363a, 363b such that the outer surface of the flat
splicing member 354 is flush with the outer surfaces of the
intermediate sections 365a, 365b of the outer skins 350a, 350b to
provide a co-planar surface along the length of the sidewall 24 on
the outside of the trailer 20. The splicing member 354 bridges the
gap formed between the panels 342a, 342b.
[0053] 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.
[0054] Attention is now directed to the fourth embodiment of the
novel joint configuration 444 shown in FIGS. 5 and 6. In this
embodiment, first and second composite panels 442a, 442b 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 splicing member provided in the previous embodiments has been
eliminated.
[0055] At one end of the first panel 442a, as shown in FIGS. 5 and
6, the outer skin 450a has a length that is substantially longer
than the length of the inner skin 448a. The ends of the inner and
outer skins 448a, 450a freely 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 the other
end of the panel 442a (not shown), the inner and outer skins 448a,
448b freely project beyond the end of the core member 446a the same
distance so as to leave an open area between the inner and outer
skins 448a, 450a.
[0056] At one end of the second panel 442b, the inner and outer
skins 448b, 450b are of the same length and freely project beyond
the 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 is
identical to the end of the first panel 442a shown in FIGS. 5 and
6.
[0057] 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.
[0058] To assemble the logistics plate 452 with the first and
second panels 442a, 442b, the end portions 470 of the logistics
plate 452 are inserted between the inner and outer skins 448a,
450a; 448b, 450b of the first and second panels 442a, 442b such
that the ends of the end portions 470 generally abut against the
ends of the core members 446a, 446b. The ends of the inner skins
448a, 448b 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 442a
extends behind the logistics plate 452 and 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 logistics plate 452, the
respective outer skins 450a, 450b and the extension of the outer
skin 450a.
[0059] The extension of the first panel outer skin 450a eliminates
the need for the separate splicing member as used in the first,
second and third embodiments. The outer skin 450a is very thin,
however, and, as such, does not provide as much reinforcement as
the splicing member provides. The extension of the first panel
outer skin 450a seals the junction between the panels 442a, 442b on
the exterior of the trailer 20 so as to seal the interior from
moisture.
[0060] Directing attention to the fifth embodiment of the novel
joint configuration 544 shown in FIG. 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 logistics plate 552 are of a substantially uniform
thickness.
[0061] 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, 548b, 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 panels 542a, 542b, the insert 576 substantially
prevents compression of the panels 542a, 542b, which can occur
during the insertion of a rivet because the core member 546a, 546b
is made of a compressible material.
[0062] Alternatively, the logistics plate 552 could be attached to
the inner surface of the inner skins 548a, 548b with the respective
inserts 576 completely filling the space between the skins 548a,
550a; 548b, 550b. In addition, the logistics plate 552 could be
attached to the inner surface of the inner skins 548a, 548b, the
insert 576 eliminated, and the core member 546a, 546b used to
completely fill the space between the skins 548a, 550a; 548a,
550a.
[0063] Directing attention to the sixth embodiment of the novel
joint configuration 644 shown in FIGS. 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 panels 642a, 642b and, like the fourth and
fifth embodiments, the splicing member provided in the previous
embodiments has been eliminated.
[0064] 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.
[0065] 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 648b. The ends of the inner and outer skins 648b,
650b freely project beyond the end of the core member 646b so as to
leave an open area between the inner and outer skins 648b, 650b at
each end of the second panel 642b.
[0066] The logistics plate 652 is identical in construction to that
described with respect to the fourth embodiment. Thus, a repetition
of the construction of the logistics plate 652 is not repeated
herein.
[0067] To assemble the logistics plate 652 with the first and
second panels 642a, 642b, the flat end portions 670 of the
logistics plate 652 are inserted between the inner and outer skins
648a, 650a; 648b, 650b of the first and second panels 642a, 642b
such that the ends of the end portions 670 generally abut against
the ends of the core members 646a, 646b. The ends of the inner
skins 648a, 648b sit adjacent to the junction between the
respective end 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 and 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
the 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 658 so that clips or the like can be
attached thereto for attaching equipment to the logistics plate
652. Rivets 668 are engaged through the respective inner 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.
[0068] Because the outer skin 650a of the first panel 642a overlays
the outer skin 650b of the second panel 642b, a bend 678 is
provided in the outer skin 650a of the first panel 642a so that the
outer skins 650a, 650b lie against each other. This forms a double
thickness behind the intermediate portion 672 of the logistics
plate 652 to 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.
[0069] 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 U.S. patent application Ser. No. 08/620,999, entitled
"Method of Punching A Composite Plate", which is commonly owned by
the assignee herein and which disclosure is herein incorporated by
reference. If desired, holes can be provided through the logistic
panel 452, 552, 652 and the panels 442a, 442b; 542a, 542b; 642a,
642b.
[0070] Attention is now directed to the seventh embodiment of the
novel joint configuration 744, shown in FIG. 11, which has
first-and second composite panels 742a, 742b. One of the panels
742b is shown in FIG. 10. It is to be understood that the other
panels used to construct the trailer sidewall are identical in
construction. At one end of the panel 742b, as shown in FIG. 10,
the inner and outer skins 748b, 750b are longer than its associated
core member 746b 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.
[0071] As shown in FIG. 11, to connect the panels 742a, 742b
together to form a sidewall 24 of the trailer 20, the coined end
portion 780b of one panel 742b is inserted between the freely
projecting inner and outer skins 748a, 750a of the adjacent panel
742a. When interconnected together, the outer surface of the inner
skin 748b of panel 742b lies against the inner surface of the inner
skin 748a of panel 742a and the outer surface of the outer skin
750b of panel 742b lies against the inner surface 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, 750a and the coined end
portion 780b.
[0072] Attention is now directed to the eighth embodiment of the
novel joint configuration 844, shown in FIG. 13, which has first
and second composite panels 842a, 842b. One of the panels 842a is
shown in FIG. 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 panel 842b, as shown in FIG. 12, the inner and
outer skins 848b, 850b are longer than its associated core member
846b so as to freely project beyond the ends of the core member
846b. The panel 842b tapers from one end to the other end such that
the distance 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 846b
tapers from one end of the panel 842b to the other end of the panel
842b.
[0073] As shown in this embodiment, an insert 876, like the insert
576 in the fifth embodiment, is provided between the freely
projecting skins 848b, 850b at the end of the panel 842b which has
the lesser thickness. The insert 876 completely fills the space
between the inner and outer skins 848b, 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.
[0074] 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 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 842a.
[0075] 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
U.S. patent application Ser. No. 08/620,999 which disclosure has
been herein incorporated by reference. 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 other panel through which the rivets
are engaged.
[0076] Directing attention to the ninth embodiment of the novel
joint configuration 944 shown in FIG. 15, this embodiment is the
same as the joint configuration 144 shown in the first embodiment
except that the construction of the splicing member 954 is
different. It is to be understood that the splicing member 954
described with respect to this embodiment can be used on any of the
embodiments in which a splicing member is provided, e.g., FIG. 5.
The
[0077] 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 the outer skins 950a, 950b of the panels
942a, 942b, the inner surfaces of the side portions 974 lie against
the planar outer skins 950a, 950b and the intermediate portion 966
bulges outwardly from the sidewall. The bulging intermediate
portion 966 of the splicing member 954 bridges the air pocket 958
formed between the panels 942a, 942b and aligns with the air pocket
958. The bulging intermediate portion 966 provides for more space
within the air pocket 958 to allow for the attachment of members,
such as clip or hooks, to the slots 962 of the logistics plate
member 952. Because the bulge is provided on the outside of the
trailer 20a, a smooth inner surface is provided within the trailer
20a. This allows for more width within the inside of the trailer
20a to load freight therein.
[0078] The flat top portion 970 and the flat bottom portion 972 of
the splicing member 954 facilitate connection of the panels 942a,
942b to the top and bottom rails 38a, 40a of the trailer 20a. In
order to connect the sidewalls 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 roof 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 of 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 the
splicing members 954 did not have the flat top and bottom portions
970, 972, but rather have the bulging intermediate portion 966
extending the entire height of each splicing member 9541 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 the splicing member 954.
[0079] 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. The splicing member 954 seals the junction
between the panels 942a, 942b on the exterior of the trailer 20a so
as to seal the interior from moisture. Moreover, because the flat
top and bottom portions 970, 972 are seated under the 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
trailer 20a or to the trailer 20a itself.
[0080] In the first, second, third and ninth embodiments of the
novel composite joint constructions 144, 244, 344, 944, to engage
the rivets 168, 268, 368, 968 with the logistics plate 152, 252,
352, 952 the splicing member 154, 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 U.S. patent application Ser.
No. 08/620,999, which disclosure has been incorporated by
reference. Coining the ends of the panels 142a, 142b; 242a, 242b;
342a, 342b; 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.
[0081] In addition, in the first, second, third and ninth
embodiments of the composite joint configurations 144, 244, 344,
944, it is envisioned that an insert, as discussed herein with
respect to the fifth embodiment shown in FIG. 7, can be provided in
the construction of these embodiments of the trailer sidewalls.
[0082] Attention is now directed to the tenth embodiment of the
novel joint configuration 1044 shown in FIG. 16. In this
embodiment, first and second composite panels 1042a, 1042b are
joined together by a logistics plate 1052 on the inside of the
trailer 20 which extends along the entire height of the panels
1042a, 1042b and the splicing member provided in the first, second,
third and ninth embodiments has been eliminated.
[0083] At one end of the first panel 1042a, as shown in FIG. 16,
the outer skin 1050a has a length that is substantially longer than
the length of the inner skin 1048a. The end of the outer skin 1050a
freely projects beyond the end of the-core member 1046a and the
inner skin 1048a. At the other end of the panel 1042a (not shown),
the inner skin 1048a, the outer skin 1050a and the core member
1046a all extend the same length in an identical structure to the
end of the second panel 1042b shown in FIG. 16.
[0084] At one end of the second panel 1042b, as shown in FIG. 16,
the inner skin 1048b, the outer skin 1050b and the core member
1046b all extend the same length. At the opposite end of the second
panel 1042b (not shown), the construction is identical to the end
of the first panel 1042a shown in FIG. 16.
[0085] Each end of the inner skins 1048a, 1048b of each panel
1042a, 1042b has an end section 1074a, 1074b (only one of which is
shown on each panel 1042a, 1042b) which includes a groove 1076a,
1076b formed therein proximate to, but spaced from, the end of the
panels 1042a, 1042b. The remainder of the inner skins 1048a, 1048b
of the panels 1042a, 1042b remain planar. When the groove 1076a,
1076b is formed in the end section 1074a, 1074b of each inner skin
1048a, 1048b, the core member 1046a, 1046b is squeezed or
compressed between the inner and outer skins 1048a, 1050a; 1048b,
1050b and the core member 1046a, 1046b may slightly extrude
outwardly from the ends of the skins 1048a, 1050a; 1048b, 1050b and
into the air pocket 1058 formed between the panels 1042a, 1042b.
The grooves 1076a, 1076b may be formed by coining.
[0086] The logistics plate 1052 acts like a post and is a member
having a flat intermediate portion 1078 with opposite edges 1080a,
1080b which are rolled. A plurality of spaced openings or slots
1062 are provided through 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
sidewalls 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 the skins 1048a, 1050a; 1048b, 1050b to
provide the sidewall with strength and rigidity.
[0087] When the logistics plate 1052 is joined with the inner 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 1048a,
1048b to substantially prevent snagging of cargo on the edges of
the logistics plate 1052. Rivets 1068 are engaged through the ends
of the logistics plate 1052, the respective inner skins 1048a,
1048b, the respective core members 1046a, 1046b and the respective
outer skins 1050a, 1050b.
[0088] The extension of the first panel outer skin 1050a eliminates
the need for the separate splicing member as used 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 extension
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.
[0089] 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 any of
the embodiments which uses a splicing member, the splicing member
may be flat or bulge outwardly and may have the flat top and bottom
portions if a bulge is provided. An insert could be provided in any
of the embodiments or eliminated in the embodiments where it is
shown.
