Application December 5, 1952, Serial No. 326,525

2 Claims. (Cl. 248-221) This invention relates to shelf supports, and more particularly to a shelf support that is adjustable, in a manner different than what is specified and claimed in my co-pending application Serial No. 45,880, dated August 24, 1948, now abandoned.

The object of my invention is to provide an adjustable shelf support that may be easily attached to a vertical angular standard.

Another object of my invention is to provide an adjustable shelf support that frictionally engages an angle iron standard.

A further object of my invention is to provide an adjustable shelf support that can be secured to an angular standard, at any desired height without the use of special tools or mechanical skill.

A still further object of my invention is to provide a means that permits constructing and erecting portable shelving in a level manner, even though it be erected on an uneven floor.

Still another object of my invention is to provide an adjustable shelf support that can accommodate any size of horizontal shelf, is simple in construction, economical to manufacture and highly eflicient for the purpose for which it is intended.

Other and further objects of my invention not particularly mentioned in the foregoing description will become more apparent as the description proceeds, and when taken in conjunction with the drawings in which:

Figure 1, is a perspective view of the adjustable shelf support attached to a portion of a vertical angle iron standard.

Figure 2 is a perspective view of the support plate.

Figure 3 is a perspective view of the support bracket.

Figure 4 is a front view of a portion of the vertical angle iron standards, showing two shelf supports attached thereto.

Figure 5 is a top or plan view of the vertical angle iron standards in cross-section showing two shelf supports attached thereto as taken at line 55 in Figure 4.

Figure 6 is a fragmentary front view of a plurality of shelf supports assembled with shelves and vertical standards, and

Figure 7 is a top or plan view of a plurality of shelf supports in combination with vertical standards and shelves, taken at line 7-7 in Figure 6.

Similar characters of reference indicate corresponding parts throughout the several views, and referring now to the same, the character 10 shows a shelf support plate of substantially triangular shape at its top 11 and having downwardly extending flanges 12 tapered at their ends 13 so that the flanges 12 are smaller at the bottom than they are at the top. The top 11 of the shelf support plate 10 is provided with apertures 14 to receive bolts, rivets or the like, not shown.

The support bracket shown as 15 is constructed of a single strip of material and formed to a contour to receive the downwardly extending flanges 12 of the shelf support plate 10. The outwardly depending ends of the Patented June 14, 1955 support brackets 15 are bent to substantially U shape at their ends 16 and are cut at 17 so that the ends 16 are narrower than the rest of the bracket. The angular bracket 15 is also bent at 18 and 18' so as to form an offset 19, of a contour to fit around the outside face of the

angle iron standards

20 and 20'.

The vertical standards 21 are constructed of a pair of angle irons 2i} and 20 joined with horizontal. spacers 22,

T 0 construct shelving, the support bracket 15 is placed on the vertical standard 22 so that the corner 19 of the bracket 15 engages the

angle iron standards

20 or 20' around the outside face thereof, at the desired height.

The shelf support plate 10 is then placed on the inside of the angle iron standard above the bracket 15 and the downwardly extending flanges 12 engage the bracket 15. As the shelf support plate 10 is brought down, the flanges 12 engage the U-shaped ends 16 of the bracket 15 wedging them between the tapered ends of the bracket 16 and the inside of the angle iron standard. The more pressure brought on the top of the shelf support 10, the tighter the bracket is secured to the standard due to the tapered ends 16 of the bracket 15 and the taper 13 on the flanges 12. The bracket 15 is cut at 17 so that the ends of the bracket are narrower, thereby allowing the shelf support to be brought flush with the top of the support bracket.

When the adjustable shelf supports are secured in position on the vertical standards, any type of shelving, whether wood or metal may be placed thereon. The shelves 23 may be laid in position as shown in Figures 6 and 7, or may be secured by means of boltsor rivets (not shown), said bolts or rivets would extend through the shelf and engage the apertures 14 of the shelf support plate 10.

It is manifest to anyone familiar with the art of constructing shelving that it is often imperative to provide a plurality of shelves of varied heights in a horizontal manner, the device described provides an efficient means of constructing shelving in a level manner even though the floor is uneven. Due to the fact that the shelf supports frictionally engage the vertical standards, it is possible to obtain any adjustment, and the support can be retained at any height on the standard.

The device described herein is both fully adjustable and portable, can be constructed to any size or shape and can be easily disassembled when the shelving has to be moved to a different location.

In the chosen embodiments of my invention, there are many features not heretofore described in the prior art, and while I may have shown a specific structure, I am fully aware of the fact that many changes may be made in its form and configuration without affecting its operativeness, and I reserve the right to make such changes as I may find convenient without departing from the spirit of the invention or the scope of the depending claims.

Having thus described my invention, what I claim and desire to secure by Letters Patent in the United States is:

1. A shelf support to be used in combination with a vertical angle iron standard, said support comprising the combination of a horizontal triangular plate and a vertical angular bracket, said plate having downwardly disposed flanges extending at right angles thereto along two of its adjoining edges, the angularly spaced ends of said flanges being tapered from their attachment to said plate to their lower edge, said bracket being bent at a right angle forming two legs for contact with the outer faces of said vertical angle iron standard, the free ends of the legs being folded to form channels, said channels being tapered in the same direction as the tapered ends of said flanges to accommodate the tapered end of the flanges on said plate when said plate is disposed thereon.

2. A shelf support to be used in combination with a vertical angle iron standard said support comprising, the combination of a horizontal plate and a vertical angular bracket, said plate having downwardly disposed flanges extending at right angles thereto along two of its adjoining edges, the angularly spaced ends of said flanges being tapered from the attachment to said plate to the lower edge thereof, said bracket being bent at a right angle at its central portion forming two legs, offsets in said legs to accommodate the sides of said vertical angle iron standard when said bracket is placed in contact with the outer sides of said vertical angle iron standard, the ends of said legs being return bent into channels closed at their ends and tapered to accommodate the tapered ends' of the flanges of said plates when said flanges engage said channels.
