The load arms include a a pair of interlocking sections having outwardly extending flanges adjacent the lower edge thereof. Deck panels are supported on the flanges of the load arms. The deck panels are constructed of an elongated planar sheet of sheet metal having opposed outer edges with a plurality of supporting members carried therebetween.

3 Claims, 3 Drawing Figures RACK ASSEMBLY This invention relates to a rack assembly, and more particularly to a rack assembly having outwardly extending load arms for supporting a planar deck panel.

There are many rack assemblies presently being utilized, but generally they are difficult to assemble and are extremely heavy, and as a result expensive.

One of the desirable features of the rack assemblies constructed in accordance with the subject invention is that articles can be readily placed on supporting decks with minimum obstructions. In many plants such articles are carried on pallets and loaded onto the racks with fork lift trucks. Often the aisles through which the fork lift trucks travel are relatively narrow, allowing a minimum amount of room for maneuvering when placing the pallet on the rack assemblies. If side bracing were utilized, such would interfere with loading the pallets on the racks. Another disadvantage of some of the rack assemblies presently being used is that the decks are not smooth and planar, therefore, it is difficult to shift articles thereover.

Accordingly, it is an important object of the present invention to provide a rigid and sturdy rack assembly which can be readily assembled.

Another important object of the present invention is to provide a rack assembly onto which articles, such as pallets and the like, can be placed thereon with a minimum of difficulty.

Still another important object of the present invention is to provide a rack assembly with a deck that remains planer whether loaded or not so as to pennit articles to be easily shifted thereacross.

Another important object of the present invention is to provide a rack assembly with load arms which extend outwardly from vertical columns constructed of a pair of interlocking sheet metal members producing a rigid and sturdy construction.

The construction designed to carry out the invention will be hereinafter described, together with other features thereof.

The invention will be more readily understood from a reading of the following specification, and by reference to the accompanying drawing forming a part thereof, wherein an example of the invention is shown and wherein:

FIG. l is a perspective view showing a portion of a rack assembly, with parts removed for purpose of clarity, constructed in accordance with the present invention,

FIG. 2 is a cross sectional view taken along line 2-2 of FIG. l illustrating the construction of the load arm, and

FIG. 3 is a fragmentary perspective view illustrating the bottom side of a deck constructed in accordance with the present invention.

Referring to FIG. 1 of the drawing, there is illustrated a rack assembly comprising aligned vertical columns A which have brackets attached thereto. Elongated load arms B extend outwardly in opposite directions from the brackets carried by the columns A. The load arms B include first and second abutting sections of sheet metal presenting opposed load bearing flanges carried by respective sections. The first section includes a channel member having one edge integral with a respective load bearing flange. The second section has an interlocking member integral with the respective load bearing flange carried within the channel member of the first section. Means, such as welding, is provided for attaching the first section to the second section so that the opposed load bearing flanges or surfaces are aligned. A deck panel C is carried on the load bearing surfaces between adjacent load arms B.

The vertical columns A may be constructed of any suitable steel members, such as channel irons. The vertical columns A have their lower ends welded between a pair of spaced transverse channel members 10 and 11, respectively. Positioned on top of the spaced chan nel members 10 and 11 and spanning the gap therebetween is an elongated U-shaped member 12 which has outwardly extending flanges 13 integral with the lower edge of a pair of spaced downwardly extending legs 14 and 15, respectively. The flanges 13 are, in turn, welded to the upper surfaces of the channel members 10 and 11. As can be seen, the lower deck panel C is carried on the flanges 13 between adjacent supporting base members which include channels l0 and 11.

The load arms B which extend outwardly in the opposite direction from the vertical column A includes first and second abutting sections 16 and 17 constructed of sheet metal and presenting opposed load bearing surfaces 18 and 19, respectively. The first section includes a channel shaped portion 20 having a lower edge integral with the horizontal load bearing surface 18. The second section 17 is carried within the channel member 20 of said first section 16 and includes an upper horizontal flange 21 and a lower horizontal member 22 which are joined by vertical side wall 23. Integral with the lower member 22 is the load bearing surface 19. The first and second abutting sections 16 and 17 are attached together by elongated welds, such as shown at 24 and 25. As can be seen in FIG. 2, the deck panels C rest on the load bearing surfaces 18 and 19, respectively. The load arms which are relatively lightweight since they are made out of sheet metal are very strong due to the fact that the first and second sections 16 and 17, respectively, includes three elongated vertical walls, as well as three elongated horizontal supporting flanges.

It is important that the upper surface of the deck panel C be smooth and planer with a minimum amount of buckling so that a load, such as carried on a pallet, may be readily shifted thereover. The deck panel is constructed of an elongated continuous sheet of sheet metal having opposed outer edges 26 and 27 which are turned downwardly and inwardly. A plurality of elongated metallic supporting members 28 in the form of elongated hat sections are carried between the opposed downwardly extending outer edges 26 and 27 and are welded to the bottom surface of the deck panel C. Transverse tie straps 29 are welded between the outer edges 26 and 27 for adding rigidity to the deck panels.

As can be seen in FIG. 1, the load arms B may take at least two different forms. The load arms B shown on the right are single load arms, whereas, the load arms shown on the left are referred to as double load arms. The single load arms are welded to a channel shaped bracket 30 which is, in turn, bolted to the vertical column A. As can be seen, the vertical column has holes 30a located in the side thereof, so that the vertical position of the load arms B may be adjusted. For purpose of clarity, the bolts which extend through holes 30a and 30h are not shown. The double load arm shown on the left has a portion of the supporting flange 19 removed so that the bracket 31 can be welded thereto. The bracket, in turn, is bolted to the vertical support arm A. Longitudinal braces in the form of elongated angle iron members 32 are attached to the vertical columns for adding rigidity to the rack assembly. Additional bracing in the form of tension rods 33 criss-cross between adjacent vertical colums A, and are secured thereto by beveled washers 34 and a nut 35. Holes are provided in the vertical columns for accommodating the tension rod 33.

The rack assembly can be readily assembly and loads can be placed on the decks C with minimum obstructions interferring with the manipulation thereof. In one particular rack assembly the deck panel is constructed of 16 gauge hot roll sheet metal and the load arms are constructed from gauge hot roll steel.

While a preferred embodiment of the invention has been described using specific terms, such description is for illustrative purposes only, and it is to be understood that changes and variations may be made without departing from the spirit or scope of the following claims.

What is claimed is:

l. A rack assembly comprising aligned vertical columns, brackets attached to said vertical columns, elongated load arms carried by said brackets and extending outwardly in opposite directions from said brackets, said load arms including first and second abutting sections of sheet metal presenting opposed elongated horizontal load bearing surfaces carried by respective sections, said first section including an inverted U shaped member defined by a pair of spaced elongated vertically extending side walls joined at the top thereof by an elongated horizontal top member, a lower edge of one of said side walls being integral with one of said horizontal load bearing surfaces, said second section including an interlocking member carried within said U shaped member of said first section, said interlocking member being defined by an elongated vertical side wall having an elongated horizontal base member integral with a bottom edge thereof, said horizontal base member being integral with said other load bearing surface, means for attaching said first section to said second section so that said opposed load bearing surfaces are aligned, and a deck panel carried on said load bearing surfaces between adjacent load arms.

2. The rack assembly as set forth in claim l, wherein said deck panel includes: an elongated continuous sheet of sheet metal having opposed outer edges turned downwardly and inwardly, a plurality of elongated metallic supporting members carried between said opposed downwardly and inwardly turned outer edges, and tie straps interconnecting said outer edges for adding rigidity to said deck panel.

3. The rack assembly as set forth in claim 2, wherein said elongated metallic supporting members are elongated metallic hat sections.
