Abstract

A universal structural support member that includes multiple holes formed therethrough is provided to attach to multiple sized horizontal beams of a storage rack, built strong enough to support multiple pallets of goods. Pre-formed holes through the structural member and/or horizontal beam can be formed in the shape of a polygon, e.g., a square hole. A bolt to attach the structural support to the horizontal beam can be formed with a key structure to interlock with the hole and prevent rotation of the nut and/or structural member. The member can be configured with multiple holes in multiple arrangements to allow the structural support member to be used with differently sized storage racks.

First claim

The invention claimed is:

1. A storage rack system constructed to support pallets loaded with goods, comprising:
a horizontal beam extending in a horizontal direction, the horizontal beam having a vertical wall extending in a vertical direction, a height in the vertical direction of about 3 inches or about 4 inches and a bolt receiving hole through the vertical wall;
a structural support having a first end, a second end, and a supportive portion therebetween, the supportive portion having a first end portion, a second end portion and a central portion therebetween, the first end portion extending from the central portion to a connection end, and a connection flange extending in a downward direction from the connection end, the connection flange having a first and a second bolt receiving hole therethrough, each a different distance from a junction of the connection end of the first end portion to the connection flange, and the first hole through the connection flange overlaps the hole through the vertical wall when the vertical wall is 3 inches and the second hole through the connection flange overlaps the hole through the vertical wall when the vertical wall is 4 inches;
a bolt attaching the structural support to the horizontal beam, the bolt having a threaded portion, a head portion, and a key structure between the threaded portion and the head portion, the bolt extending through the bolt receiving hole of the horizontal beam and the connection flange;
the bolt receiving hole through the horizontal beam or the connection flange having a locking shape to engage the key structure and resist twisting of the bolt with respect to the locking shaped hole; and
the key structure configured to interlock with the locking shaped bolt receiving hole through the connection flange or the horizontal beam and resist rotation of the bolt with respect to the connection flange or horizontal beam.

2. The storage rack system of claim 1 , wherein the bolt receiving hole through both the vertical wall of the horizontal beam and the connection flange have the shape of a polygon and the key structure interlocks with the polygon shaped holes through the vertical wall and the connection flange and the key structure is adapted to resist rotation of the connection flange with respect to the vertical wall.

3. The storage rack system of claim 1 , wherein the hole through the connection flange and the cross section of the key structure both have a square shape with substantially the same dimensions.

4. The storage rack system of claim 1 , wherein:
the vertical wall of the horizontal beam has a top flange at the top of the vertical wall, and the top flange has an upper surface and a lower surface;
a top surface of the central portion of the supportive portion defines a first plane, a top surface of the first end portion slopes downward from the first plane, and the top surface of the first end portion is positioned at the lower surface of the top flange.

5. A storage rack system constructed to support pallets loaded with goods, comprising:
a horizontal beam extending in a horizontal direction, the horizontal beam having a vertical wall extending in a vertical direction and a height in the vertical direction of about 3, about 3.5, or about 4 inches, and a bolt receiving hole through the vertical wall;
a structural support having a central supportive portion having a first end portion and a second end portion, the first end portion extending to a connection end having a connection flange extending in a downward direction from the connection end, the connection flange having a first, a second, and a third bolt receiving hole therethrough, each a different distance from a junction of the connection end to the connection flange, and the first hole through the connection flange overlaps the hole through the vertical wall when the vertical wall is about 3 inches, the second hole overlaps the hole through the vertical wall when the vertical wall is about 3.5 inches, and the third hole overlaps the hole through the vertical wall when the vertical wall is about 4 inches in height;
a bolt attaching the structural support to the horizontal beam, the bolt having a threaded portion, a head portion, and a key structure between the threaded portion and the head portion, the bolt extending through the holes through the horizontal beam and the connection flange;
the hole through the horizontal beam or the connection flange having a locking shape to engage the key structure and resist twisting of the bolt with respect to the locking shaped hole; and
the key structure configured to interlock with the locking shaped hole through the connection flange or the horizontal beam and resist rotation of the bolt with respect to the connection flange or horizontal beam.

6. The storage rack system of claim 5 , wherein the first, second and third holes are arranged diagonally on the connection flange.

7. A storage rack system constructed to support pallets loaded with goods, comprising:
a horizontal beam extending in a horizontal direction, the horizontal beam having a vertical wall extending in a vertical direction, and a bolt receiving hole through the vertical wall;
a structural support having a supportive portion having a first end portion, a second end portion, and a central portion therebetween, the first end portion extending to a connection end, and a connection flange extending in a downward direction from the connection end, the connection flange having a bolt receiving hole therethrough;
a bolt attaching the structural support to the horizontal beam, the bolt having a threaded portion, a head portion, and a key structure between the threaded portion and the head portion, the bolt extending through the bolt receiving holes of the horizontal beam and the connection flange;
the bolt receiving hole through the horizontal beam or the connection flange having a locking shape to engage the key structure and resist twisting of the bolt with respect to the locking shaped hole;
the key structure configured to interlock with the locking shaped bolt receiving hole through the connection flange or the horizontal beam and resist rotation of the bolt with respect to the connection flange or horizontal beam;
wherein a top surface of the central portion of the supportive portion defines a first plane, the first end portion slopes downward from the first plane, and a top surface of the first end portion defines a second plane and a third plane, the second plane closer to the central portion than is the third plane and the second plane forms a larger angle downward from the first plane than the angle between the third plane and the first plane.

8. A structural support, comprising:
a first end portion, a second end portion, and a central portion therebetween, the central portion extending in a horizontal direction and having a top surface defining a first plane;
the first end portion extending from the central portion to a connection flange at a first end of the first end portion, the first end portion sloping downward from the first plane, wherein the first end of the first end portion is offset downward from the first plane;
the connection flange substantially perpendicular to the first plane and having a connection hole in the shape of a polygon therethrough; and
a top surface of the first end portion defines two sloping surfaces, each at a different angle with respect to the first plane.

9. The structural support of claim 8 , wherein the connection hole is in the shape of a square.

10. The structural support of claim 8 , wherein the connection hole is in the shape of a regular polygon and the connection flange is at least about 1/16 inch thick.
