DETAILED DESCRIPTION OF THE INVENTION

[0022] FIGS. 1 and 2 illustrate one possible usage of spacer pads constructed in accordance with the present invention. Spacer pads 20 are placed between rolls 22 that are being transported by a truck 24. Rolls 22 might be, for example, rolls of paper or coiled metal that should be protected from being damaged while being transported by shipping container 24 by way of truck or rail car.

[0023] Referring to FIGS. 3, 4, and 5, a first embodiment of a spacer pad 30, constructed in accordance with the present invention, includes a first vertical rail 32, a second vertical rail 34, a first horizontal rung 36, and a second horizontal rung 38. Rung 36 is secured at a first end 36a to rail 32 and at a second end 36b to rail 34. Rung 38 is secured at a first end 38a to rail 32 and at a second end 38b to vertical rail 34. More specifically, rungs 36 and 38 are secured to rails 32 and 34 by interlocks with the rails having slots that receive the rungs and the rungs having slots that receive the rails. A third horizontal rung 40 is included in spacer pad 30 to indicate that spacer pad 30 can have more than two horizontal rungs

[0024] Rails 32 and 34 and rungs 36 and 38 can be paperboard. As illustrated in FIGS. 3 and 5, rails 32 and 34 and rungs 36 and 38 can be laminated paperboard or, as illustrated in FIGS. 6 and 7, rungs 38 and 40 and rails 32 and 34 can be multiple layers of corrugated paperboard.

[0025] Referring to FIGS. 8 and 9, a second embodiment of a spacer pad, constructed in accordance with the present invention, includes a foam layer 50 and a plurality of wedge-shaped blocks 52 attached to a surface 50a of the foam layer at selected locations. As shown most clearly in FIG. 9, for the embodiment of the present invention illustrated and being described, each wedge-shaped block 52 is a right-angle isosceles triangle that is attached to surface 50a of foam layer 50 by one of the legs of the triangle.

[0026] Referring to FIG. 10, a third embodiment of the present invention of a spacer pad, constructed in accordance with the present invention, is generally similar to the second embodiment of the present invention illustrated in FIGS. 8 and 9. The embodiment of the present invention illustrated in FIG. 10 includes a first plurality of wedge-shaped blocks 60 (only two are shown in FIG. 10) attached to a first surface 62a of a foam layer 62 and a second plurality of wedge-shaped blocks 64 (only two are shown in FIG. 10) attached to a second surface 62b, opposite first surface 62a, of foam layer 62, at selected locations. For the embodiment of the present invention illustrated and being described, each wedge-shaped block 64 is a right-angle isosceles triangle that is attached to foam layer 62 by one of the legs of the isosceles right triangle.

[0032] Spacer pad 70 further includes a third horizontal rung 80 secured at a first end 80a to a first side 72a of first vertical rail 72 and at a second end 80b to a second side of the second vertical rail 74.

[0033] Spacer pad 70 further includes a fourth horizontal rung 82 secured at a first end 82a to a second side of the first vertical rail 72 and at a second end 82b to a second side of the first vertical rail 72.

[0034] For the embodiment of the invention illustrated and being described, spacer pad 70 also includes a fifth horizontal rung 84 and a sixth horizontal rung 86 to indicate that spacer pad 70 can have more than four horizontal rungs.

Spacer pad 70 further includes: [0035] a first wedge-shaped block 90 attached to first horizontal rung 76 at a first end 76 to the first horizontal rung [0036] a second wedge-shaped block 92 attached to first horizontal rung 76 at a second end of the first horizontal rung [0037] a third wedge-shaped block 94 attached to second horizontal rung 78 at a first end to the second horizontal rung [0038] a fourth wedge-shaped block 96 attached to the second horizontal rung 78 at a second end to the second horizontal rung [0039] a fifth wedge-shaped block 98 attached to the third horizontal rung at a first end to the third horizontal rung [0040] a sixth wedge-shaped block 100 attached to the third horizontal rung at a second end to the third horizontal rung [0041] a seventh wedge-shaped block 102 attached to the fourth horizontal rung at a first end to the seventh horizontal rung [0042] an eighth wedge-shaped block 104 attached to the fourth horizontal rung at a second end to the fourth horizontal rung [0043] an eighth wedge-shaped block 106 attached to the fourth horizontal rung at a second end to the fourth horizontal rung [0044] an eighth wedge-shaped block 108 attached to the fourth horizontal rung at a second end to the fourth horizontal rung [0045] an eighth wedge-shaped block 110 attached to the fourth horizontal rung at a second end to the fourth horizontal rung [0046] an eighth wedge-shaped block 112 attached to the fourth horizontal rung at a second end to the fourth horizontal rung
