ATTORNEYS.

RACK FRAME My invention relates to rack frames of the general type used for piling in superimposed tiers bars, slabs or boards, and rods or tubes. Such material is usually piled in a convenient location for storage and for ready access or withdrawal of the material. I

An object of my invention is to provide an improved rack frame easily and readily handled, sturdy and strong in use, and readily adaptable for interfltting with other similar rack frames superimposed in a tier arrangement. Other objects and a fuller understanding of the invention may be had by referring to the following description and claims, taken in conjunction with the accompanying drawing in which:

FIG. 1 is a side elevational view of my improved rack frame in a preferred form of the same;

FIG. 2 is an end view of the rack frame looking in the direction of the arrows 2-2 of FIG. 1;

FIG. 3 is a top plane view of my rack frame and looking in the direction of the arrows 3-3 of FIG. 1; and

FIG. 4 is a perspective view ofa number of my rack frames, all similar in structure, superimposed in a tier arrangement and holding bars, slabs and rods as illustrated.

My rack frame, denoted generally by character reference 11, has a horizontally disposed base member preferably made of metal. This base member has a horizontal flat web portion 12A and two downwardly extending flange portions 128 along the opposite longitudinal edges of the web portion. The two flange portions 123 each have inturned flange portions 12C along the bottom edges thereof and directed toward each other as better seen in FIG. 2.

The two inturned flange portions 12C do not extend as much toward the ends of the base member as do the web portion 12A and the side flange portions 123. The opposite ends 12D of the inturned flange portions 12C form stop or abutment portions of the base member. It is to be noted that the two stop or abutment portions 12D are spaced-apart less than the overall length of the base member and each stop or abutment end surface 12D is spaced inboard from its respective end of the web portion 12A and flange portions 128. There is thus a pocket formed at each end of the base member, which pocket is disposed outboard of the stop or abutment surface 12D and intermediate the side flanges 128 under the web portion 12A.

There may be added if desired end pieces 13 welded to the bottom of the web portion 12A and spaced, as seen in FIG. 2, from the side flanges 128. These pieces 13 are positioned at the outer extreme ends of the web portion 12A and well outboard of the location of abutting end surfaces 12D. Planes normal to the base member extending through each of the abutting end surfaces 12D are spaced considerably from parallel planes normal to the base member and passing through the closet side of the most adjacent pieces 13. In the normal use and function of the rack frame the pieces 13 do not perform any function but may be added if preferred as a safety feature to the structure shown.

Rigidly secured, as by welding, to the metal base member are two uprights also of metal. Preferably, the metal of both the base member and the uprights are of a suitable steel or a steel alloy of required strength. Each upright has a web portion 14A disposed to face inwardly toward the corresponding web portion 14A of the other upright. The included space above the base member and between the web portions 14A of the uprights accommodates a load thereon, such as bars and rods. Extending along the opposite edges of the web portion 14A and directed toward the ends of the rack frame, that is away from the open space between the uprights, there are flange portions 143. As the outermost edges of the portions 143 are disposed normal to the base member, and as the web portion 14A are inclined so as to diverge away from each other, it will be seen that the flange portions 143 are go general triangular form as seen in FIG. I. The upper ends of the uprights are cut off at a right angle to the planes of the web portions 14A and hence at an obtuse angle to the rear or outward edge of the flange portion 148. Thus the triangular form of the flange portions 148 are somewhat truncated as illustrated. The structure and arrangement of the uprights on the base member is such as to give strength, rigidity and a good bracing action to the uprights.

Extending between the flange portions 148 of each upright is a bar 15 which provides areadily graspable handle for lifting and maneuvering the rack frame. The bars 15 are disposed at a location intermediate the upper ends 14C and the base member in such a position that upon one grasping one of the handles 15 and raising the rack frame it will hang or be suspended in such a manner that the base member is substantially vertical. This provides for ready lifting and maneuvering of the rack frame.

The improved rack frame is such that the upper end portions of a similar rack frame below will fit into the pockets at the ends of the similar rack frame above. It is to be noted that the web portions 14A of the rack frame below engage, or are positioned immediately adjacent, the stop or abutting end surfaces lZD, respectively, of the rack frame above. This interfitting between the upper ends of the web portions 14A of the frame below and the abutting end surfaces 12D of the frame above is such as to prevent longitudinal movement of one frame member relative to the other frame member. By longitudinal movement I am referring to movement from right to left or from left to right as seen in FIG. 1 which is longitudinally of the base member. It is also seen that the upper end portions of the uprights of the frame below, and particularly the flange portions 128 thereof, fit closely between the side flanges MB of the frame below disposed outboard of the abutting end surfaces 12D. Thus, lateral movement of one frame member relative to the other frame member is prevented by the side flanges 12A confining the upper end portions of the frame below.

It is to be noted that the upper end portions of the uprights of the frame below do not normally engaged or contact the supplementary end pieces 13. Only if and when the uprights under excessive strain and load would be distorted and would thus be spread apart would the upper end portions of the frame below engage the pieces 13 of the frame above. The end pieces 13 thus provide only safety factors, if desired, to confine the upper end portions of the uprights of the frame below within the pockets of the frame above should the uprights of the frame below be abnormally forced apart. In the normal and proper use of my rack frames this does not occur and the end pieces 13 become nonfunctional and would be eliminated.

An illustration of the way in which my improved rack frames may be utilized is seen in FIG. 4 wherein there are six similar rack frames in a tier arrangement. Three are superimposed upon each other atone location and three other similar frames are superimposed upon each other at another location. The open spaces between the uprights are in alignment and thus ready for accommodation of loads thereon. In the illustrated arrangement there are a plurality of metal bars 16 disposed in the upper tier, a plurality of slabs or boards 17 in the intermediate tier, and a plurality of rods or tubes 18 in the lowermost tier. The tier may be readily built up or disassembled in the manner described. Any number of tiers may be constructed as desired.

The present disclosure includes that contained in the appended claims, as well as that of foregoing description.

Although this invention has been described in its preferred form with a certain degree of particularity, it is understood that the present disclosure of the preferred form has been made only by way of example and that numerous changes in the details of construction and the combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as hereinafter claimed.
