Filed June 27, v 1940 INVENTOR 1 B fl/berf 56/6? Y Q ATTORNEY Patented Apr. 22, 1941 UNITED STATES PATENT OFFICE RACK AND BASE Albert Bersin, New York, N. Y. Application June 27,1940, Serial'No. 342,640

(o1. zu isz) 7 Claims.

This invention relates to a rack and abase therefor. The rack is one which is composed of rods, bars or tubes, preferably of metal. Such a rack is one which is useful for hanging or displaying clothes, drapes, hangings or the like. The particular embodiment of a rack shown herein is one suitable for displaying drapes of different lengths.

It is a particular object of the present invention to provide a base which will serve to stiffen a rack longitudinally and at the same time provide good lateral support. By providing a yoke which is offset longitudinally at its upper portion from its legs, a truss effect is obtained for the base which results in a substantial longitudinal bracing of the structure. Other forms of rack than that shown may be used with my base and provided with its longitudinal bracing effect. Said base is particularly adapted for a relatively long rack.

My base and rack are readily assembled from the individual pieces or parts constituting them. This is of advantage so that they may be shipped without being assembled, and further where the rack and base are to be plated, the parts may be plated before assembly. It is not convenient to do the plating alter assembly. Where the parts are plated it is not feasible to take advantage of the stiffening action of welded connections because welding mars the plating.

Other objects and advantages will become apparent upon further study of the description and drawing, in which Fig. 1 is an elevation of a rack of my construction with a base or support in accordance alsowith my construction.

Fig. 2 is a sectional plan taken along the line 22 of Fig. 1.

Fig. 3 is a partial sectional plan to an enlarged scale taken along the line 3-3 of Fig. 1.

Fig. 4 is an enlarged section at the junction of one tube with another and shows the detail of the fastening of the tubes to each other.

Fig. 5 is a partial section to an enlarged scale taken along the line 5--5 of Fig. 2, and

Fig. 6 is a partial end elevation to an enlarged scale taken along the line 6-6 of Fig. 1.

The rack comprises upright members I bent over at their tops to have horizontal portions 8. The two tallest upright members 9, however. are joined together at their tops by a horizontal portion l0, forming with said latter members an inverted elongated U. All the upright members are supported on a horizontal member I i. Each end of member ll frames into a cross bar l2.

The cross bar 12 at each end of member H in turn extends between the generally downwardly extending legs [3 of a yoke M. The upper portion of each yoke I 4 bows inwardly toward the other yoke M. In other words, the convex side of one yoke when viewed from above, as in Fig. 2, points to the convex side of the other yoke. The end upright!) and the end upright 1 each extend downwardly through the top of a yoke hi at its extremely inwardly olfset location, said uprights extending downwardly from the yokes Hi to their connection with horizontal member I I. At the intersection, Fig. 5, of upright member 9 andthe upper portion of yoke I4 a pin or screw 22 is passed through both. This pin may be omitted as it is not essential to the connection, but if used will supply an additional source of stiifness to the construction. A strong bracing action is produced longitudinally at each end of the rack by the horizontal offsetting of the yoke l4 combined with the fact that the end upright member frames to member I l at a distance away from cross bar l2. Where yoke I4 is formed of a bar having a shape of considerable vertical depth or diameter where end uprights 9 or 1 pass through it, said end uprights are braced against rotation about their lower ends as a pivot on bar I I, even with pin 22 omitted. The greater said vertical depth or diameter the greater the binding action of the yoke on the upright where it passes through. A further bracing action is obtained for the end uprights by their connection to each other at their tops through the horizontal portions 8 of all the uprights intermediate as well as end. The fact that portions 8 are not'all at the same height increases the stiffening action. The fact that uprights 9 are integral with each other at the top also produces a stiffening action. In other words bracing and connecting the end uprights at their itops prevents their rotation about their lower ends, increasing the effectiveness of the offset yokes as braces. While the end uprights are preferably attached or fastened to the yokes by passing through them, it will be understood by those skilled in the art that other ways of fastening can be used, such as bolting them together without the end uprights passing through the yokes.

A further advantage of framing the uprights to member II at a distance away from cross bar I2 is that it avoids the framing of three bars together at one intersection.

The term bar as used herein, including the claims, is intended to be broad enough to cover a tube except as evident otherwise from the context. The cross sectional shape of the bar is preferably circular but other forms, such as square could be used.

In Fig. 4 is shown a typical detail of fastening one tube to the other. It is used at all the meeting places of tubes where the rack is built up of tubes except where the end upright members pass through yokes I4. Assuming that the joint shown in Fig. 4 is between one of the uprights I and horizontal member II, a washer I5 is welded to the inside of upright I. A tapped hole is provided in washer I5 for receiving the threaded end of a screw I6. Screw I6 passes through aligned holes in horizontal member II, the head of the screw being nested in the bottom hole which is countersunk. Upright I is milled out at its end so that it has the proper a member I and a member 9 are horizontal bars I! to be used for suspending drapes or the like therefrom. They are in reality screws such as screw I6, the threaded end, not seen, engaging one of the uprights while the head, also not seen, nests in the adjacent upright. From the horizontal portions 8 are upwardly extending clips I 6 which hold descriptive cards I9 relating to drapes or other goods which are to be hung from bars IT. The differences in height of the upright members enables them to support drapes or goods of diiferent lengths.

An additional support 2| is provided under bar H to prevent undue sagging,

In Fig. 1, the upright members are shown as being of unequal height increasing in height from right to left, except the two at the extreme left. It will be readily understood that this pattern can be modified by having the members increase or decrease in height in a different order. For example, the two tallest members 9 might be in the middle of the rack with the others successively decreasing in height to the right and to the left.
