- 3 Claims.

My invention relates to the storage and handling of large rugs or carpets, and consists in certain new and useful improvements in a rack for supportinga plurality of rolled rugs in salesrooms and warehouses.

Retail stores necessarily carrylarge inventories of assorted rugs and carpets to meet the varied tastes or requirements of the purchasing public, and the large salesrooms for the display of such inventories are very costly to staff and maintain. Considerable labor is required to move the rugs into position where they may be suitably considered by customers. This has presented a problem that has remained unsolved through the years.

In the solution, of the problem, my invention consists in a traveling'rack which is adapted to be easily and quickly moved from an out-of-theway storage area into a display area, whereby the rugs on the rack may be severally viewed and inspected. Individual rugs may be readily removed. from the rack, or placed upon it, and in due course the rack and its burden of rugs may be returned to the storage area.

It is important to note that the construction of the rack is designed for cooperation with a fork lift-truck, a well-known device that has recently come into wide general use in the handling of various materials. Furthermore, the rack is adjustable at will for rugs of various sizes.

The invention will be understood upon reference to the accompanying drawings, in which:

Fig. 1 is a view in side elevation of a rug rack embodying the invention, it being noted that a certain adjustable element of the structure is shown in dotted lines in an alternate position from that in which it appears in full lines;

Fig. 2 is a view of the rack on horizontal section, as seen on the plane IIII of Fig. 1;

Fig. 3 is a view in vertical section of one of the adjustable supports of the rack, the plane of section being indicated at III-III in Fig. 1; and

Fig. 4 is a view of the rack structure, as seen on the plane IV -IV of Fig. 1.

Referring to the drawings, the rack will be understood to be formed principally of metal tubes and beams of standard sections, preferably steel sections, which are readily available on the open market at the present time, whereby uniformity and economy of construction are obtained, and ready interchangeability of parts is afforded.

The rack structure comprises a base 2 in the form of a rigid frame, which is rectangular as viewed in plan, Fig. 2. This basal frame is built rectangular cross section.

of lengths of steel angles, two lengths 3, 3 forming the sides, two lengths 4, 4 the ends, and two lengths 5, 5 a medial reinforcement. The base is rigidly integrated by welding, and at the four corners gusset-plates 1 further reinforce the structure. Under each of the four corners of the base a swivel caster 8 is secured, and at the middle of the frame two non-swivel casters or wheels 9 are provided. The structural steel frame and its six casters afford a sturdy traveling chassis upon which the rug-supporting members of the rack are mounted.

Th rug-supporting members of the rack comprise five trees or supports a, b, c, d and e, each having a central trunk or mast 6, from which three pairs of branches or arms l0 extend in alignment. As will presently appear the two end supports a ande are adjustable, to make accommodation for rolled rugs of various lengths, and to permit a balancing of the rug load on the rack. All of the masts 6 are conveniently formed of steel I-beam sections, and the masts of the three supports b, c and d are mounted rigidly upon the base 2. The mast of the central support c extends at its lower end downwardly between, and is welded to, the two cross braces 5, 5 of the base, and the three pairs of arms iii are at their inner ends. ll (Figs. 2 and a) rigidly welded to the mast, with the arms of each pair aligned transversely of the rack structure. The arms are formed of steel I-beam sections; the

lower pair of arms is welded to the base 2, providing for still further reinforcement of the struc .ture, and the other two pairs of arms are spaced upwardly therefrom bya distance slightly but sufficiently in excess of the diameter of the rugs to be carried by the rack. The three pairs of arms .of the five supports a to e are identically spaced in the vertical, whereby the arms provide on each side of the line of masts 6 three flights of fivehorizontally aligned arms l8, each flight being arranged to receive and support 2. rolled rug R. p

Whereas the three supports 1), c and d are rigidly mounted upon the base 2, the end supports a and e are adjustable on the longitudinal axis of the rack structure,whereby the effective length of the five supports may be modified to suit rolled rugs of various lengths. Each of the supports a and e is borne by three horizontal I-beam sections [2, welded at their outer ends to the mast portion 6 of the support (a or e) and telescoped at their inner ends in steel tubes l3 of square or The tubes l3 are welded at their inner ends to the mast 6 of the central support 0, and at their outer ends to the masts 6 of the supports 1) and d, respectively. While the mast 6 of each of the supports a, c and e is formed of a continuous length of steel beam, the masts 6 of the supports b and d are made in three sections 60, 6| and 62 welded at their upper and lower ends to the outer ends of the tubes [3; the two lower tubes extending from the opposite sides (Fig. 1) of the mast 6 of the central support are welded to the base 2, as are the bottom arms lfi'of the three rigid supports 2), c and (1. Thus it is that great strength and rigidity are obtained in a structure built of rela-- tively light structural metal sections, and a sturdy telescope frame or carriage is provided for the members i2 that adjustably bear the end supports a and e.

As already mentioned, the "members i2 which mount the adjustable end supports a and e in the tubes !3 are formed of lengths of standard structural steel I-beams; the tubes l3 are three in number for each of the supports a and e, and. they are vertically spaced, lying in the three horizontal planes, respectively, in which the three flights of arms lie on the opposite sides of the row of masts 6; the tubes [3 are formed of lengths of square steel tubing-a standard product of the tube mill, and the adaptation of lengths of such tubing to form the telescopic receptacles for the I-beam members I? of the adjustable end supports a and e is of great practical value. It will be noted that the members I? are positioned with the flanges of their I-beam section arranged to bear on the inner surfaces of the top and bottom walls of the associated tube members [3, whereby greatest strength is obtained; that is, strength of the supports a and e to withstand the vertical loads imposed by the rolls of rugs introduced to the rack structure. On the other hand, the frictional engagement of the telescopic parts I2 and I3 is minimized, whereby the adjustment of the end supports a and e may be readily made. More specifically, the bodies of the I-beam members I2 bear upon the side walls of the tubes 13 only along the edges of the top and bottom flanges of the I-beam, and thus the friction of the engagement of the members 12 with the internal surfaces of the tubes i3 is minimized. Additionally, the 2' section of members l2 within the square tubes It eliminates the possibility of air becoming entrapped within the tubes I3, to resist the telescopic movement of the members 12. The telescoped parts l2 and 13 provide means of ample strength and rigidity to support the heavy rolls of rugs R, while admitting of ready adjustment of the end supports a and c.

The manner in which a conventional fork-lift truck (not shown) may be used to p ck-up a rolled rug broadside, and to carry it, lift it, and place on any of the three flights of arms is on either side of the rack structure, will be readily understood bv those skilled in the art. And such .a lift truck may be also readily used in removing rugs from the rack.

In order to prevent the rugs from rolling from supported position on the arms I i], detents are provided at the ends of such ar s. Advantageously. such means comprise chocks l4 that are removablv secured to the arms. As shown in Figs. 1 and 4 the chocks M are formed of short sections of angle iron, having two pin or finger portions l5, (Fig. 1) provided on one edge of the an le. The chocks are p sitioned with their free edges directed downwardly upon the top surfaces of the respective arms [0, and the two pins on each chock are extended through orifices formed in the arm ID, as will be understood upon reference to Fig. l. The provision of chocks [4 at the end of each of the five arms of each rugsupporting flight of arms insures that the rug cannot be unintentionally dislodged from supported position while the rack and its burden are being moved from place to place. And it is noteworthy that the chocks are readily and quickly removable from secure position of attachment to the arms.

In some cases the tops of the masts 6 of the supports 1), c and d may be interconnected by a welded steel strap or beam l6, thereby providing in a rack for unusually heavy rugs additional reinforcement of the three medial masts.

Within the terms of the appended claims various modifications in the structure described may be made without departing from the spirit of the invention. I claim:
