Locking cross bar

1. A shelf-type storage rack system having improved locking cross bars comprising:

at least one pair of parallel spaced front columns;

at least one pair of parallel spaced rear columns;

at least one generally horizontal front deck beam interconnected between the at least one pair of spaced front columns, the front deck beam including an outer face, and an upper flange, the entire upper width of which defines an upper support width for at least one locking cross bar, and at least one aperture in said outer face;

at least one generally horizontal rear deck beam interconnected between the at least two rear columns, the rear deck beam including an outer face and an upper flange, the entire upper width of which defines an upper support width for said at least one locking cross bar; and

said at least one locking cross bar interconnecting said front and rear deck beams to form a support surface, said locking cross bar having a front end and adapted at a front end to include a vertical overhanging portion having a locking tab to lockingly engage the at least one aperture on said outer face of the at least one front deck beam, be supported by said upper support width of said front deck beam, and, having a rear end being adapted at a rear end to include a vertical overhanging portion that overhangs and is supported by said upper support width of said rear deck beam.

2. The invention of claim 1 wherein the rear end of said locking cross bar is adapted to lockingly engage a slot and be supported by said rear deck beam.

3. The invention of claim 1 wherein the front end of said locking cross bar includes a vertical overhang portion, said vertical overhang portion being tapered.

4. A shelf-type storage rack comprising:

at least one pair of spaced, parallel front columns;

at least one pair of spaced, parallel rear columns;

at least one front deck beam spanning between said front columns, said front deck beam having an outer face which is adapted to include an aperture and an upper support width;

at least one rear deck beam spanning between said rear columns, said rear deck beam having an outer face and an upper flange, the entire upper width of which defines an upper support width for at least one cross bar; and

said at least one cross bar spanning between said front and said rear deck beams and forming a support surface, said cross bar having a front end that includes a vertical overhang portion with a locking tab to lockingly engage said aperture on said outer face of said front deck beam and having a rear end to engage said upper support width of said rear deck beam, said cross bar being supported by said upper support widths of said front and rear deck beams.

5. The invention of claim 4 wherein said front vertical overhang portion is tapered.

6. The invention of claim 4 wherein said locking tab is hooked.

7. The invention of claim 4 wherein said locking tab is flat.

8. The invention of claim 4 wherein the rear end of said cross bar has a rear vertical overhang portion.

9. The invention of claim 8 wherein said outer face of said rear deck beam includes at least one aperture and said rear vertical overhang portion of said cross bar includes a tab to engage said aperture on said rear deck beam.

10. A shelf-type storage rack system having improved locking cross bars comprising:

at least one pair of parallel spaced front columns;

at least one pair of parallel spaced rear columns;

at least one generally horizontal rear deck beam interconnected between the at least one pair of spaced rear columns, the rear deck beam including an outer face, an upper support width and at least one aperture in said outer face;

at least one generally horizontal front deck beam interconnected between the at least two front columns, the front deck beam including an outer face and an upper support width; and

at least one locking cross bar interconnecting said front and rear deck beams to form a support surface, said locking cross bar having a rear end and adapted at said rear end to include a vertical overhanging portion having a locking tab to lockingly engage the at least one aperture on said outer face of the at least one rear deck beam, be supported by said support width of said rear deck beam, and, having a front end being adapted at said front end to include a vertical overhanging portion that overhangs and is supported by said upper support width of said front deck beam.

11. The invention of claim 10 wherein the front end of said locking cross bar is adapted to lockingly engage a slot and be supported by said rear deck beam.

12. The invention of claim 10 wherein the rear end of said locking cross bar includes a vertical overhang portion, said vertical overhang portion being tapered.
