Cross bar
First Claim
1. A cross bar for interconnecting spaced-apart beams in a rack construction wherein each beam has an elongated ledge with a plurality of longitudinally spaced-apart apertures therein, said cross bar comprising an elongated platform adapted to span the beam ledges and having spaced-apart support legs for supporting said platform in a mounted position on the ledges, and a mounting tab extending outwardly from one of said legs adjacent to one end thereof, said tab being dimensioned and arranged to fit within a selected one of the apertures in the beam ledges with said cross bar in the mounted position thereof to interlock said cross bar with the beams for preventing accidental dislodgement of said cross bar in use.

Abstract
A cross bar is provided for interconnecting two parallel spaced-apart beams of a rack construction, wherein each beam has an inner ledge having a plurality of longitudinally spaced-apart apertures therein. The cross bar is in the form of a rectangular open-bottom channel member with one leg longer than the other, the long leg being integral along the entire lower edge thereof with a laterally outwardly extending flange. Two notches are respectively formed in the flange predetermined short distances from the opposite ends thereof, with the portions of the flange between the notches and the adjacent ends defining tabs dimensioned for insertion into selected ones of the apertures in the beams so that the short leg of the cross bar will rest upon the beam ledges with the top of the cross bar disposed substantially horizontally, the inner edges of the beam ledges being accommodated in the cross bar notches.

- 1. A cross bar for interconnecting spaced-apart beams in a rack construction wherein each beam has an elongated ledge with a plurality of longitudinally spaced-apart apertures therein, said cross bar comprising an elongated platform adapted to span the beam ledges and having spaced-apart support legs for supporting said platform in a mounted position on the ledges, and a mounting tab extending outwardly from one of said legs adjacent to one end thereof, said tab being dimensioned and arranged to fit within a selected one of the apertures in the beam ledges with said cross bar in the mounted position thereof to interlock said cross bar with the beams for preventing accidental dislodgement of said cross bar in use.
- 5. A cross bar for interconnecting spaced-apart beams in a rack construction wherein each beam has an elongated ledge with a plurality of longitudinally spaced-apart apertures therein, said cross bar comprising an elongated platform adapted to span the beam ledges and having first and second elongated spaced-apart support legs extending therefrom substantially normal thereto along substantially the entire length thereof, a flange carried by said first leg and extending laterally outwardly therefrom along substantially the entire length thereof, said flange having a notch formed therein a predetermined short distance from one end thereof with the portion of said flange between said one end and said notch defining a tab, said tab being dimensioned and arranged for insertion into a selected one of the apertures in the beam ledges to a mounting configuration wherein the upper surface of said tab is disposed beneath the lower surface of the ledge and the bottom edge of said second leg is supported upon the ledge and the inner edge of the ledge is accommodated in the notch, whereby said cross bar is interlocked with the beam for preventing accidental dislodgement of said cross bar in use.
- 8. A cross bar for interconnecting spaced-apart beams in a rack construction wherein each beam has an elongated ledge with a plurality of longitudinally spaced-apart apertures therein, said cross bar comprising an elongated platform adapted to span the beam ledges and having first and second elongated spaced-apart support legs extending therefrom substantially normal thereto along substantially the entire length thereof, said first leg extending further from said platform than said second leg, a flange carried by said first leg at the distal end thereof and extending laterally outwardly therefrom along substantially the entire length thereof, said flange having a notch formed therein a predetermined short distance from one end thereof with the portion of said flange between said one end and said notch defining a tab, said tab being dimensioned and arranged for insertion into a selected one of the apertures in the beam ledges to a mounting configuration wherein the upper surface of said tab is disposed beneath the lower surface of the ledge and the bottom edge of said second leg is supported upon the ledge and the inner edge of the ledge is accommodated in the notch, the lengths of said first and second legs being such that when said cross bar is disposed in the mounting configuration thereof said platform is disposed substantially parallel to said ledges, whereby said cross bar is interlocked with the beam for preventing accidental dislodgement of said cross bar in use.

14. In a rack construction, the combination comprising a pair of elongated spaced-apart beams, each of said beams including an elongated generally rectangular ledge and an elongated shoulder extending upwardly from said ledge substantially normal thereto along substantially the entire length thereof, said ledge having a plurality of longitudinally spaced-apart apertures therein;
- and a cross bar including an elongated platform adapted to span said beam ledges and having first and second elongated spaced-apart support legs extending therefrom substantially normal thereto along substantially the entire length thereof, said first leg extending further from said platform than said second leg, and a flange carried by said first leg at the distal end thereof and extending laterally outwardly therefrom along substantially the entire length thereof, said flange having a notch formed therein a predetermined short distance from one end thereof with the portion of said flange between said one end and said notch defining a tab, said tab being dimensioned and arranged for insertion into a selected one of the apertures in said beam ledges to a mounting configuration wherein the upper surface of said tab is disposed beneath the lower surface of said ledge and the bottom edge of said second leg is supported upon said ledge and the inner edge of said ledge is accommodated in said notch;
the lengths of said first and second legs being such that when said cross bar is disposed in the mounting configuration thereof said platform is disposed substantially parallel to said ledges, whereby said cross bar is interlocked with said beam for preventing accidental dislodgement of said cross bar in use. - View Dependent Claims (15, 16, 17, 18, 19)
