DETAILED DESCRIPTION EMBODIMENTS OF THE INVENTION

[0035] Referring to the figures, the embodiments of the invention are described in detail.

[0036] FIGS. 3-8 show a composite panel or a trailer with the composite panel applied.

[0037] An object of the invention is to provide a forming for composite panel for imparting strength, which can prevent the composite panel from vibrating due to air friction.

[0038] Another object of the invention is to provide a forming for composite panel for imparting strength, which is strong enough even without increasing the number of rivet joint portions.

[0039] A composite panel 100 for container 900 with wheels 910 comprises a first panel portion 10, one or more first bending portions 12, a second panel portion 20, one or more second bending portions 22, and a rivet joint portion 30 as shown in FIGS. 3-5.

[0040] The first panel portion 10 comprises an outer plate 14 and an inner plate 16 disposed with an even interval therebetween and having specific height and width as shown in FIGS. 4, 6, and 7.

[0041] The one or more first bending portions 12 are provided vertically through the outer plate 14 and the inner plate 16 of the first panel portion 10 as shown in FIG. 5.

[0042] The second panel portion 20 comprises an outer plate 24 and an inner plate 26 disposed with an even interval therebetween and having specific height and width as shown in FIGS. 4, 6, and 7. Even though the details are omitted for second panel portion 20 in FIG. 3, it has an exactly same structure as the first panel portion 10.

[0043] The one or more second bending portions 22 are provided vertically through the outer plate 24 and the inner plate 26 of the second panel portion 20.

[0044] The rivet joint portion 30 connects the first panel portion 10 and the second panel portion 20 as shown in FIG. 3.

[0045] The one or more first and second bending portions 12, 22 are configured for imparting structural strength to the composite panel 100 against vibrational or deformational force in a direction perpendicular to the first or second panel portion 10, 20 and all across the entire wall of the trailer 900.

[0046] The one or more first or second bending portions 12, 22 provided through the outer plate 14, 24 may be aligned with corresponding bending portions 12, 22 provided through the inner plate 16, 26.

[0047] The composite panel 100 may further comprise filling material (not shown) disposed between the outer plate 14, 24 and the inner plate 16, 26 of the first or second panel portion 10, 20.

[0048] The two neighboring bending portions 12, 22 may define an embossing portion 40 or a protruding portion 50, and the embossing portion 40 and the protruding portion 50 are disposed next to each other so as to be provided alternatingly horizontally across the first or second panel portion 10, 20 as shown in FIGS. 4, 6, and 7.

[0049] The embossing portion 40 may have a same width as the protruding portion 50. In certain embodiment of the invention, the embossing portion 40 may have a width shorter than that of the protruding portion 50 as shown in FIGS. 4, 6-8.

[0050] Each stripe portion connecting the embossing portion 40 and the protruding portion 50 may be perpendicular to the surface of the embossing portion 40 and the protruding portion 50.

[0051] Each stripe portion connecting the embossing portion 40 and the protruding portion 50 may be tilted outwards as shown in FIG. 4, 6-8. The tilting angle may be in a range from about 5 degrees to about 60 degrees, or even larger as long as it gives a needed strength, with respect to a vertical line to the composite panel 100.

[0052] Alternatively, each each stripe portion connecting the embossing portion 40 and the protruding portion 50 may be tilted inwards. The tilting angle may be in a range from about 5 degrees to about 60 degrees, again or even larger as long as it gives a needed strength, with respect to a vertical line to the composite panel 100.

[0053] The first or second panel portion 10, 20 may have a width of approximately 1184.3 mm and a height of approximately 2700 mm, and wherein the first or second panel portion 10, 20 comprises about 15 to 25 first or second bending portions 12, 22 and about 6 to 12 embossing portions 40 as shown in FIGS. 4, 6, and 7.

[0054] Each of the embossing portions 40 may have a bottom (floor) width of about 20 mm, each of the protruding portion 50 has a top width of about 75.55 mm, and a horizontal distance from an edge of bottom of the embossing portion 40 to an edge of top neighboring the edge of bottom of the embossing portion 40 is about 8.4 mm, and wherein the even interval between the outer plate 14, 24 and the inner plate 16, 26 is about 6.5 mm as shown in FIG. 6. These dimensions are just for an embodiments. Therefore, the detailed dimensions and angles can be varied according to the situation of the problem to solve.

[0055] The composite panels according to the present invention can be made of steel or aluminum, and applied to a dry container, a box car, or exterior material in construction.

[0056] The forming or bending itself of the above material such as steel or aluminum can be made using a technology known to the community of the art. The forming or bending introduced into the outer plate and the inner plate in such an inventive way according to the invention strengthen the resulting composite drastically.

[0057] While the invention has been shown and described with reference to different embodiments thereof, it will be appreciated by those skilled in the art that variations in form, detail, compositions and operation may be made without departing from the spirit and scope of the invention as defined by the accompanying claims.
