12 Claims, 2 Drawing Figures FREE STANDING SHELF SUPPORT UNITS AND. SYSTEM BACKGROUND OF THE INVENTION This invention generally relates to shelf-type devices and more particularly to novel free standing-type, collapsible-shelf support units and system which is particularly suited for displaying merchandise in showrooms and the like.
Display shelves or stands for articles of merchandise have heretoforetaken a variety of forms. In the past, stands and the shelf-type supports for displayingmerchandisehave been bulky, unsuited for easy movement from place to place and relatively expensive to manufacture. A-majority of the known shelves on showroom floors are supported by upright members which must be physically attached to the walls making them relatively inconvenient, inflexible and expensive.
Accordingly, it is an object of this invention to provide a novel shelf assembly of a relatively inexpensive design, lightweight and highly portable which is particularly effective in displaying articles of merchandise without appreciably detracting from the merchandise.
'Still another object of this invention is to provide novel shelf support units which may be used individually to support shelves or easily stacked one on another to meet specific shelf capacity requirements and are readily adjusted and disposed in different arrangements to meet specific shelf width and length requirements.
Yet a further object ofthis invention is to provide novel free standing shelf support units formed of two hinged sections particularly suited for being made. of relatively small metal rods welded together in rigid frameworks.
Still'a. further object of this invention is to provide novel free standing shelf units capableof being stacked one onthe other for maximum display and adjustable by pivoting-the sections to accomodate different shelf widths and'lengths and the sections of each unit may be collapsed when not in use or'for storage or transportation purposes.
In accordance with the present invention in a preferred formshown there is provided'a base shelf-support unitand an upper shelf support unit which stacks on the base unit. Each unit is of a generally similar size, shape and construction preferably being made of metal rods welded together in integral frameworks. Each shelf-support unit has two framework sections pivotally connected together. to swing freely between an open angularly disposedposition and a collapsed position. Each sectionxhas a plurality of spaced horizontal shelf support members, and outer vertical compression member and an inner common vertical compression member making up the framework.

FIG. l2-is a top plan view of a shelf support system representing two of the base shelf support units arranged in opposed relation facing. one another and supporting a common relatively wide shelf.
Referring nowto the drawings, in FIG, 1 there isshown a free standing, collapsibleshelf'system having a baseshelf support unit A and a demountable upper shelf support unit B releasably mounted .on the base shelf support unit together'with a plurality of shelvesiof different shapes and sizes designated from top to bot: torn by numerals 3, 4, 5, 6 and 7,.respectively, these shelves being removably supported on the units A'- and B atvertically spaced intervals. Because of the flexibil-. ity and adjustability of the base support units asv described more fully hereinafter the shelves may be a variety of shapes and sizes. As shown in FIG. 1, the'lower shelf 3 is triangular in shape; shelf 4 is circular; shelf 5 is square; shelf 6 is rectangular; shelf7 is rectangular and broken away to show that the other end-may extend'to an adjacent support.
The base self support unit A has two sections generally designated'by numerals 11 and 12' pivotally connected'together for free swingingmovement about a common vertical axis. Section 11 is in the form of an integralbox-shaped framework comprised of an innervertical compression member 13 and outer vertical compressionmember l4-together with an upper shelf support member IS'connected at its ends to the inner and outer compression members 11 andl3 andan. intermediate shelf support member 16 connectedL-at its ends to the verticalcompression members l1.and.l3to
form an upper box-shaped framework portion. Section 11 also includes a lower shelf support member 17"connected at its ends between the vertical compression members 11 and 13m form with the intermediate shelf support member 16, a lower boxshaped framework portion. An outwardly and downwardly extendingdiagonal brace member 18 isconnected at its ends between the upper shelf supporting member 15"and outer vertical compression member 14 in the upper framework portion and an outwardly and downwardly extending diagonal brace member 19 is connected at its ends be tween the intermediate shelf support member 16 and outer vertical compression member 11 in the lower framework portion to further strengthen the base unit to carry greater loads on the shelves. As shown, the lower ends of these diagonal brace members terminate above the associated lower shelf support member a sufficient distance so as not to interfere with the shelf thereon and are suited for supporting shelves on an incline.
A lower horizontal shelf support member 27 is connected at its outer end to vertical member 24 and has a forked inner end portion formed by upper and lower washers 27a and 27b, respectively, surrounding mem ber 13 and embracing the inner end of horizontal shelf support member 17 of section 11 to form a pivotal or hinged connection and complete a lower box-shaped framework portion again using the common vertical compression member 13 for support. An outwardly and downwardly extending diagonal brace member 28 is connected to its ends between the upper shelf support member 25 and outer vertical compression member 24 for added strength and an outwardly and downwardly extending diagonal brace member 29 is connected to its upper end to horizontal shelf support member 26 and at its lower end to outer vertical compression member 24. An upper extension 24a of member 24 extends above the member 25 and a lower extension 24b of member 24 extends below member 27 and terminates in a foot-31 coextensive with feet 21 and 22.

Section 31 has an inner vertical compression member 33 and an outer vertical compression member 34 together with an upper shelf support member 35 and an intermediate shelf support member 36 to form the upper boxshaped framework portion reinforced by a diagonal brace member 38. The lower box-shaped framework utilizes intermediate shelf support member 36 and is reinforced by a diagonal brace member 39 but has no lower horizontal shelf support member corresponding with that of the base unit so the lower framework portion is only three-sided with a diagonal brace for two sides.
A sleeve 41 is affixed to the lower end of the common vertical compression member 33, a sleeve 42 is affixed to the lower end of 34, and a sleeve 51 is affixed to the lower end of member 44 forming the female part of a female coupling. These couplings releasably telescope down on the upper extensions 24a, 13a and 14a of the base unit. The detail of the sleeve is shown in FIG. 8 wherein sleeve 41 is shown as telescoping over the lower end portion of rod 33 and is welded thereto.
In use the sections of the shelf support unit are placed at a selected angle relative to one another preferably at an angle between 60 and depending on the width of the shelves. The outer edge of the shelves normally abut against the inside of the vertical compression members. The construction of the sections is preferably a solid metal rod on the order of 5/16 inch in diameter and welded together at the connections.
In the use of the above described system, either of the base or upper units are free standing and as shown the base unit supports three shelves and the upper unit two so that either may serve as separate shelf support units depending on the height required. Once assembled, the two units swing conjointly about a common vertical axis. Moreover, the shelf support unit may be positioned so that either side may face in a forward direction as represented in FIGS. 9 and 10 wherein the support unit A supporting a shelf 51 may be considered as having the outer vertical compression member 12 at.
the rear in FIG. 9 while the reverse is true in FIG. 10.
Referring now to FIG. 11, two of the units A arranged side by side are shown supporting a longer shelf 52 while in FIG. 12 two units each designated A and facing one another are shown to support a shelf 53 of substantial width to illustrate the high versatility and flexibility of a shelf system in accordance with the present invention.
