6 Claims. (Cl. 211-176) This invention relates generally to cantilever racks, and specifically to front loading brackets for such racks, with locking retainers. vIt is an object of the invention to provide a cantilever rack which has the convenience of front loading brackets.

ICC

cal column 12 may be standard stock. The vertical coly' umn r12 is provided-with a series of holes 13 in the web A portion of the rear face or rear wall y16. The vertical It is yet another object of the invention to provide a cantilever rack with rigid locking retainers.

A still further object of the invention is to provide a cantilever rack which is economical, .by reason of the use of standard, mill-rolled beams which arerelatively inexpensive.

Another object of the invention is to provide a canti lever rack which is extremely -exible in use, is fully adjus'table to intermediate heights, may be single or double sided, is free standing, may be coupled in a series with other columns, is sturdy and safe because the cantilever arms are entirely free of accidental displacement yet are at all times readily adjustable.

These objects and advantages, as well as other objects and advantages may be attained by the rack shown by way of illustration of the inventive concept vin the drawings in which: Y A Y FIGURE 1 is aview `in perspective of a cantilever rack;

FIGURE 2 is a view in perspective of a portion of an H-beam column;

FIGURE 3 is a view in perspective of a cantilever ann;

FIGURE 4 is a top view of a portion of the cantilever arm; a

FIGURE 5 is a view in perspective of a retainer;

FIGURE 6 is a top, partially sectioned view of a column, with a cantilever arm locked in place by the retainer;

FIGURE 7 is a partially sectioned view in perspective o'f a column, with a'cantilever arm locked in place by a retainer.

Cantilever rack systems which are adjustable are often inconvenient, for they cannot be readily moved, the' arms are not readily added as required, nor are they readily removable if not required; they are costly since they are made from specially fabricated parts, and are diicult to adjust. `It has been found that cantilever arms may be provided for a rack system which can easily be front loaded (i.e. applied to an H-beam at any chosen point on the face without being hoisted to the top of the beam in order to be titted into embracing relationship with the beam). Likewise, the described cantilever arm can be removed Without being lifted over and oi at the top. Yet such a cantilever arm can be quickly and easily attached to the Habeam without any danger of it slipping. The H-beams stand free in their own sturdy base and need no attachment to any wall surface to sustain them.

They can 'be made to many desired different heights, with cross-bracing of various widths, and many cantilever arms may be applied. C-antilever arms may be added, subtracted, and readjusted to suit the requirements of the user. The positive positioning of the cantilever arms does not permit any loose attachment that might result in the arms assuming a position in which the outer end is below horizontal.

Referring now to the drawing in detail, the cantilever rack provides a base 111, which may be an H-beam of 'standard design. A vertical column 12 in the form of an.

H-beam is attached to the base 11. Likewise, this verticolumn 12 is braced by side plates 18 connecting the vertical column 12 and the base 11. The vertical co1- umns 12, mounted on a base 11, are arranged in pairs (see FIG. 1) and secured together by spacer assemblies .19 attached to the columns 12. lf the columns are to be used with both front and rear cantilever arms, the base 11 may be extended rearwardly to provide balance for the back load.

A bracket of special design is provided for the columns i12. In the rtigures, the bracket 20 is shown shorter than it actually would be in order that it may not obscure other details if drawn to scale. The bracket 20 has a generally U-shaped horizontal cross section with a front wall 21 which has an internal width (as shown in FIG. 6) which is wider than either of the faces 15, l16 of the H-beam. This extra width is necessary -to enable the bracket 20 to bel applied to the face 15 without hoisting it to the top of and sliding vit down the face 15 of the column 12. The bracket 10 has Arearwardly extending legs 22, 2.12 which embrace the column 12. The .bracket 20 is provided with two generally vertical ri-

bs

23, 25 on the inner aspect of the legs 22, I22. These

ribs

23, 25 are positioned differently from each other. The tirst rib 23 isvspaced away :from the rear wall 24 of the bracket 20 a distance only suicient to receive the end portion of i the face 15 of the column 12. The second rib 25, however, is spaced away a sufiicient distance to receive the opposite end portion of the face '15 and also to receive a leg of a retainer 26 as shown in FIGURE 6.

The retainer or angle 26 has two legs; a front leg 27, and a rear leg 28. The retainer 26 has a number of elongated bolt slots 29 in the rear leg 28. When the front leg 27 is engaged with the second rib 25 at the back of the face 1'5, a bolt 30 is inserted through the holes 29, `1,3 (or 17) and a nut 31 is applied and tightened. The Ifillet (concaved junction) 32 is engaged by the convex juncture of the

legs

27, 28 and the retainer is firmly secured to the web ,14. The face 15 is firmly seized between the bracket 20 and the front leg 27. F or further security, a stop 33 is attached to the inner aspect of the leg 27, and is positioned to engage the bottom of the second rib 25 on the bracket 20. Since the ri-b 23 cannot pass the stop 33, the bracket 20 is both functionally held and is also supported at the chosen level. The cantilevered arm 34 (usually more ellongatedthan shown) supports the material to be stored.

Itis noted that the face 15 is rearwardly thicker immediately adjacent to the fillet 32, so that the retainer 26 will tend to engage only a portion of the back of the face 25 (see FIGURE 6) and will strongly engage the second rib 25.

A sturdy rack of stability, made of standard structural members is provided, at low cost, ease of assembly, and convenience of adjustment.

The foregoing description is intended merely to illustrate an embodiment of the invention, for many changes in the selection, construction and arrangement of the parts may be made within the scope of the appended claims without departing from the spirit of the invention.
