Weldless shelf support beams and shelving units utilizing same
A shelf support beam for use in a shelving unit to support a shelf. The support beam includes a first end and a second end at opposite longitudinal ends of the shelf support beam between which a structural member extends. The structural member has a C-shaped cross-section and includes a web separating a top flange configured to support the shelf from a bottom flange. The support beam further includes a tab located at each of the first and second ends of the structural member. Each tab includes a pair of securing fingers that are angled relative to a plane disposed perpendicular to a longitudinal axis of the shelf support beam such that each securing finger is angled inwardly toward a center of the structural member. The support beam further includes an enforcement tab formed in the web at each of the first and second ends of the structural member.
1. A shelf support beam for use in a shelving unit to support a shelf, comprising:
a first end and a second end located at opposite longitudinal ends of the shelf support beam between which a structural member extends, the structural member having a C-shaped cross-section that defines a channel and including a web separating a top flange that is configured to support the shelf from a bottom flange;
a tab located at each of the first and second ends of the structural member; and
at least one securing finger formed in each tab, each at least one securing finger including a stiffening rib and being angled inwardly toward the channel relative to a plane disposed perpendicular to a longitudinal axis of the shelf support beam to define a securing finger angle for the at least one securing finger.
2. The shelf support beam of claim 1 , wherein the at least one securing finger comprises a pair of securing fingers formed in each tab.
3. The shelf support beam of claim 1 , further comprising an enforcement tab formed in the web at each of the first and second ends of the structural member.
4. The shelf support beam of claim 1 , wherein the stiffening rib arcuately extends from a first terminal end on the tab to a second terminal end on the at least one securing finger.
5. The shelf support beam of claim 4 , wherein the stiffening rib includes a raised spine that extends between the first terminal end to the second terminal end.
6. The shelf support beam of claim 1 , wherein the at least one securing finger and stiffening rib are punch-formed.
7. The shelf support beam of claim 1 , wherein the securing finger angle for the at least one securing finger is within a range of between 10° to 20°.
8. The shelf support beam of claim 1 , wherein the at least one securing finger is bent inwardly from the tab on a side of the shelf support beam on which the channel is located.
9. The shelf support beam of claim 1 , wherein the at least one securing finger includes an inner surface and an outer surface that are curved.
10. The shelf support beam of claim 9 , wherein the at least one securing finger includes an S-shaped cross-section.
11. The shelf support beam of claim 1 , wherein the shelf support beam is formed as a unitary piece.
12. The shelf support beam of claim 1 , wherein the top flange and the bottom flange are truncated at each of the first and second ends of the shelf support beam to define abutment edges.
13. The shelf support beam of claim 12 , wherein each tab is an extension of the web and extends a distance beyond the abutment edges at the first and second ends of the shelf support beam.
14. A shelving unit comprising:
a plurality of posts;
a plurality of shelves; and
a plurality of shelf support beams of claim 1 , each being configured to be attached to two posts of the plurality of posts to support one of the plurality of shelves.
