LIBRARY STACKS AND BASE SUPPORTS THEREFOR The invention is for library stacks and the construction thereof, and includes special base elements, upright supports, and shelves, with joints so designed as to facilitate quick assembly of the components into a finished self-supporting fixed shelf stack, multiple shelf stacks, and movable shelf stacks. Spread footings of special construction are employed for optimum stability, with upright end posts carried by the footings, and the posts provided with slotted openings to receive locking projections of shelf supported brackets, the brackets in turn being constructed for firm supporting engagement with shelves.

This invention is an improvement on my previous inventions relating to bookstacks entitled Base Bracket for Shelves, US. Pat. No. 3,157,252 granted Nov. 17, 1964, and Library Post Structure, US. Pat. No. 3,325,017, granted June 13,1967.

An object of this present improvement invention is to provide a novel and improved base and shelving construction, in which there are a number of base and shelving components constructed and arranged for being cooperatively interfitted to form a complete stacking array, and said base being provided with leveling means to compensate for irregularities in the supporting floor.

Another object of the invention is to provide a novel and improved base and shelving construction in which there are a number of upright main support posts engageable with stable interfitting base members, there being a number of shelves extending in the same or in opposite directions from the main posts, and engageable at various elevations therewith.

A further object of the invention is to provide a novel and improved shelving and shelving construction, in which all the parts are formed for quick assembly to make up the finished shelving array, and in which the parts can be made of sheet materials and by mass production methods.

Still another object of the invention is to provide a novel and improved base and shelving construction, in which all the parts can be shipped to the site for erection, in knocked-down packaging, and quickly assembled and erected by relatively unskilled labor, or by the purchasers of the shelving, so as to minimize the ultimate cost of the units, and the cost of shipping the storage. I

Still a further object of the invention is to provide a novel and improved base and shelving construction which is usable for schools, libraries, and other places, for supporting books, files, catalogues, and other items, or in stores, for exhibiting merchandise, and in which the elevation of the shelves is in dividually adjustable, and wherein a top counter wall may be mounted on the upright posts to serve as a table level counter.

The above and other objects and advantages of the invention will become apparent from the description of a preferred embodiment thereof, as illustrated in the accompanying drawings, forming a part hereof. In the drawings:

FIG. 1 is a perspective exploded view of a shelving construction according to the invention, the upright post and shelves being shown in fragment.

FIG. 2 is a side elevational view of a shelving array in erected installed form, the view being in fragment.

FIG. 3 is a right end elevational view of the shelving array shown in FIG. 2.

FIG. 4 is a fragmentary perspective detail view of a modified form of the invention showing a different type leveling screw FIG. 5 is a detail of FIG. 1 showing particularly the configuration of anchor means 26 and 28 and base means 10.

In connection with the manufacture and use .of shelving, various problems have arisen, which it is the intent of the present invention to solve. Thus, the shelving must not be unduly massive or bulky, especially for shipping and where the installation is for temporary use. Further, it should be capable of being quickly and simply installed and erected. In addition, it should be relatively free standing, so that if desired, there will be no necessity for penetrating into the floor or walls or ceiling for supporting the shelving. Such shelving should also be easily assembled and disassembled! for storage or shipping, so as to avoid excessive costs in reaching the job site or in storage when not in use.

The present invention provides adequate shelving construction which meets these requirements. In order to understand clearly the nature of the invention, and the best means for carrying it out, reference may be had to the drawings, in which like numerals denote similar parts throughout the several views.

As shown best in FIG. 1, there is a special stable base, "S" or Z member 10, with a web portion 12 interconnecting top and bottom flanges 14 and 16 formed integral therewith. Leveling screws 18 are threaded into holes 20 in the bottom flange l6, and areturnable by a pliers or wrench to maintain the base member 10 in horizontal position for optimum stability of the entire shelving array when assembled and installed, despite incidental unevenness or lack of level surface of the floor therebelow. In order to furnish support for the upright posts 22, anchor support members 24 are provided as seen best in FIG. I, which are engaged with the base member 10, and then engaged with the upright posts 22 as hereinafter described.

From FIG. I, it is seen that the anchor support members 24 may be formed of two complementary plates 26 and 28, which may be secured to each other by any desired fastening means, such as by spot welding 30, or other means. It can be seen that plate 26 has two flanges 32 and 34, while plate 28 has two flanges 36 and 38. As also seen in FIG. 1, the flanges 32 and 34 of plate 26 are cut away or notched out at 40, so that the edge 40 rests upon the flange 14 of the main base 10, the remainder of the lower portion of the plate 26 lying against the web 12 of the base I0. The remaining two flanges 36 and 38 of the plate 28 have their lower ends 42 resting upon the flange 16 ofthe base 10.

Bolts or rivets 44 extend through matching openings 46 formed through the plates 26, 28 and web 12, to hold the anchor support members 24 firmly to the base member 10. The upper ends of the anchor support members 24 may be rounded off as shown .in FIG. 1, for easy assembly with the upright posts 22. As seen in FIG. 1, the upright posts 22 are formed of sheet material, such as sheet iron, steel or aluminum of suitable strength, with four walls 50, 52, 54 and 56, to define a hollow central area or passage 58 which is large enough in cross section to fit snugly over the upstanding anchor support member 24, with its lower edges 60 resting upon the base flanges 14 of the base member 10.

While the upright support'posts 22 may be made by bending sheet iron or steel in a bending brake, they may also be made by other methods, such as by extrusion forming, especially where the posts are made of such metals as aluminum which lend themselves to such modes of forming. As seen in FIG. 1, slots 62 are formed in the walls of the support posts 22, for engagement with the shelf supporting brackets 64, the brackets 64 having projecting teeth 66 which extend into the slots 62 to hold the bracket 64 in place.

Shelves 68 extend between parallel shelf support brackets 64, and have reduced projections 70 extending into sockets 72 in the brackets 64, being secured therein by any suitable means, such as by pressure force, metal fasteners, or by forming an end flange on each shelf projection 70 which depends slightly over and below the opening of the sockets 72 when inserted therein, thus holding the shelf therein. The shelves 68 may be formed of relatively light weight sheet metal, with edge flanges 74 for increased strength without adding bulk. Safety spacers 76 may be carried on the shelf support brackets 64 to prevent swaying of individual sections and to reinforce each section by the adjacent sections.

It is thus apparent that as seen in FIG. 1, there are a number of substantially free standing upright support posts 22 carried by engagement with their related main base members 10 and the intervening anchor posts 24. Two such spaced support posts 22 and members 10 and 24 can furnish the support array for two or more shelves 68, extending on opposite sides of posts 22, and vertically spaced shelves 68, to any height, depending on the height of posts 22.

In order to further secure the adjacent stack units together, there is provided interior rail channel 80, which is formed of sheet metal with edge flanges 82, and which extend between the flanges 32 and 34 of the anchor members 24. The rail channel may merely rest on flange 14 or may be extending through the slots 84 and holes 86 in these members. The interior rail channels 80 thus interconnect adjacent pairs of anchor members 24, or may if desired, connect directly to the related posts 22 by forming suitable holes and flanges for this purpose.

Adjacent pairs of base members (see FIG. 1) are secured together by end rails or base enclosure 88a, formed of sheet metal with top and bottom flanges 90 and 92, and end flanges 94; the flanges 94 having slots 96 for adjustability and engagement by means of screws or bolts 98 with openings 100 in web 12 of base 5" member 10.

As mentioned before, adjustable screws 18, operating through apertures 110 in flange l6, serve to level the entire assembly.

FIG. 4 shows a modified form of the invention. ln this form, the bottom flange 92 of end rails 88a are formed as in FIG. 1. However, instead of the bottom flanges of adjacent stacks abutting each other, and the flange of the second stack underlying the leveling screw 18 of the first stack for example whereby additional rigidity is imparted to each stack, the end section 9217 of flange 92a is cut off or bent out of the way so that flange 16 may rest directly on the carpet. Screw 112 has a tapered end 114 for penetrating carpeting, linoleum, or other underlayments so as to contact and be supported on a permanently solid concrete or other supporting surface. This con struction permits better alignment and leveling of the stack array with the floor and ability to maintain every one of the posts in a vertical position.

The rail members 80 and 88a secure the base members in a good strong stable base array for the stacking thereabove of the shelves. The shelves are secured in place to the upright posts 22 as shown and as described in my prior U.S. Pat. No. 3,157,252 and 3,325,017. At the tops of the posts 22 there are either lateral and longitudinal rails 102 secured to the upper ends of the posts 22, or a roof ceiling, or wall forming a closure at the top of the assembled shelving stacks for strength and rigidity. In any events, the posts 22 are thus secured firmly against sidewise dislodgment or displacement from the vertica'l. Where the height of the stack array is only about table or counter height, then 102 may be of suitable material such as plywood or plastic with an attractive upper surface, to act as a counter above the books or merchandise on the shelves therebelow.

Although a preferred embodiment of the invention has been described and illustrated in specific terms, it is understood that various changes may be made in size, shape, materials and arrangement without departing from the spirit and scope of the invention as claimed.

From the above it is clearly apparent that my invention has the following advantages.

1. The unit can be quickly and easily assembled and disassembled without the use of special tools.

2. It adds rigidity to the unit by inserting interlocking members into the lower portion of the upright. This stiffens the upright and also provides a strong stiff member to connect to the footing.

3. The ends of the footings are provided with screw adjustment for leveling and plumbing. Because of the footing design these screw adjustments are at the maximum distance from the centerline of the upright, which in turn provides maximum stability.

4. The base enclosure 88a is attached to the foot (see FIG.

1) by means of a bolt 98 elongated slot 96. This slot permits the base enclosure 88a to be adjusted to enclose the space between the bottom shelf 68 and the floor. The end of the adjusting screw 18, rests on the bottom flange 92 of the base enclosure 88a of the next unit which distributes the bookstack load over a large area to minimize floor load at a single point.

5. In the modification illustrated in H6. 4, the end section 92b of bottom flange 92a may be bent out of the way or cut off when carpet glide 112 (operating through aperture is substituted for adjustment screw 18.

6. This design permits easy adaptability of the bookstack to stationary or to sliding bookstacks known as compact stacks, i.e., stacks mounted on sliding platforms which roll of wheels. The sturdiness of this platform meets the design requirements for compact stacks.
