1 The present invention :relates to nfiultiple leg frame stands, tripods, and equivalent supports such as are used for suspeiiding bags and similar articles for filling or dispensing purposes, and has'reference in parti cular to-a structural assemblage in this fieldofendeavor which isof a so-called knock-down type, this to facilitate ready assembling and-disassembling as wellas collapsing same into compact and convenient form -for storage'and shipment.

-As is evident'from the foregoingv introduction and general statement of-theinvention, I am not particularly concerned with w-hether the invention isused as a bag 'support or forsoine other purpose, but am primarilyinterested in the construction of the support itself. It follows, therefore,'that an object of the'invention is to structurally, functionally, and otherwise'improve upon supports in this-same field of invention, 'this through-themedium of acarefully-chosen selec-- tion of parts, said parts being expressly-fashioned and designed for: interfitti-ng mechanical relationship to provide a sturdy structure when same is set up for useyand to'make'for more convenient and compact packagingwhen the structure is collapsedio'r storage, shipping. or other ha'ndling. v

i More specifically,movltyisthought to reside in a practical and convenient, multiple leg, elevated and supporte'd frame, the frame'being of general circular form and made upof--separably-interconnected sections, the sections I having overlapped ends and including means 'wherebyad'jacent upper-ends of the legs 'are'accommodated, this in such-a manner that the legs assemble the frame-sections and also'thusmaintain themselves in place.

Reference: being had to thespreferredembodiment as herein shown and hereinafter particularly described, it will be seen that further novelty has to do with a circular sectional frame, the sections being of segmental form and provided with alternate slots and staple-like retainers protruding through the slots, the retainers being shaped and arranged to provide keepers, the upper, adjacent ends of the detachable legs being expressly designed to fit into the keepers and against the frame sections in such a manner as to provide for ready erection and disassembling and proper correlation of parts.

Other and more specific features, objects and advantages will become more readily apparent from the following description and the accompanying illustrative drawings.

Figure 6 is-an-enlarged fragmentary top edge view employed to bringout certain of the interfitting elements and to'bett'er-show --the overlapped ends of the frame sections and mode of attaching a leg thereto.

As before'explained, I am not especially interested whether-the structure is employed as a holder fora bag or for some other type of article. However, in the drawings I; have shown the same used as abag holder, the bag A being of open net formfor containing-and dispensing calcium chloride and there being a -basin-or pan B'lo cated beneath side bagf'or trapping purposes.

Referring totheframe, this is :generally denotedin Figured -by-the numeral (,said frame being of appropriate sheet 1 material and being here shown-as made up of three complemental and duplicate frame sections -8, each of segmental form. As said sections are counterparts of one another, a description of one will 'sufiice for all. Tothisend,'each'section as shown in Figures 3 and 4 is provided atone end with an assembling slot 9 and atthe oppositeend with a struck out strap It], said strap being bent to provide a looplike keeper. The extreme upper edge of the band or section 8, directly above and in alinement with the slot 9, is indented and the indentation defines an outwardly projecting detent H which serves in a manner to be hereinafter described. Between the parts 9, l0 and II, said band is punctured and the punctured portions are struck out to provide tongues 12 which are pointed and constitute spurs to facilitate holding the open mouth of the bag in properly supported position on the complete assembled frame, as shown in Figure 1. It is obvious that when said frame is assembled, the keeper loop ID at one end extends through and projects beyond the adjacent accommodation or adapter slot 9 at the end of the coactin section. Thus, the coacting ends of the respective sections overlap and the keeper loops ID extend through the slots 9 in readiness for the leg-assembling steps. The legs are here shown as of appropriate length. They are duplicates of one another and each leg is denoted by the numeral I3 and is preferably channelshaped in cross-section and provided with a rubber foot or pad 14 at the bottom. The upper portion of the web, downwardly of the extreme upper end, is indented and fashioned into a projection l5 which constitutes a stop shoulder and which is engageable with the keeper loop as shown in Figure 1. That portion of the leg beyond said shoulder is transversely flattened and laterally bent to provide a retaining and assembling tang l6. This is brought out to better advantage in Figure 6, where it will be seen that in addition to being laterally bent the edge flanges are flattened, as at IT, thus providing between themselves a retention seat for the aforementioned detent l l. Observing, therefore, the overlapping ends of two of the frame sections, it will be seen that the keeper loop l6 protrudes through and beyond the coacting slot 9. Then the tang 16 on the upper end of the leg is pushed through the loop and is brought into resting contact with the adjacent surface of the coacting frame section 8. The shoulder l5 rests against the lower edge of the keeper loop and the detent ll seats itself in the retention seat provided between the inbent, flattened flanges I! on said tang. This interfitting and coacting relationship of parts serves to hold the legs in place and also permits the legs to lock or fasten the frame sections together in properly assembled relationship. It is obvious, too, that by detaching the legs they can be packaged compactly in relation to one another and also the frame may be likewise knocked down and the parts collapsed for compactness and convenience.

In view of the foregoing description taken in conjunction with the accompanying drawings, it is believed that a clear understanding of the and at the opposite end with an outstanding loop, said loop constituting a keeper, and said band also having one edge portion formed with an indentation, said indentation constituting a leg assembling detent and being in alignment with said slot.

2. In a structure of the class described, a sectional frame of circular form, the sections each being of segmental form, each section having a slot at one end and an outstanding loop-like keeper at the opposite end, the adjacent ends of respective sections being disposed in overlapping relation, the loops projecting through the slots for connecting said overlapping ends together,

and supporting legs, the upper ends of said legs being laterally offset to provide assembling tangs, said tangs projecting removably into the respective loops, this in a manner to permit the tangs to coact with the loops and adjacent portions of the ends of said sections in assembling the frame and also the legs and to provide a knock down bag or equivalent support.

3. In a structure of the class described, a sectional frame of circular form, there being a plurality of said sections and each section being of segmental form, each section having a slot at one end and a detent lined up with said slot, and each section having an outstanding keeper loop at the opposite end, adjacentends of said sections being overlapped and the loops projecting through the slots for frame assembling and leg accommodation purposes, the respective detents being aligned with the loops, and a plurality of supporting legs, there being one leg for each loop construction, operation and advantages of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though I have herein shown and described a preferred embodiment of my invention that the same is susceptible to certain changes fully comprehended by the spirit of the invention as herein described and within the scope of the appended claims.

I claim:

1. As a new article of manufacture and as a component part of a frame, a segmental band, aid band being provided atone end with a slot and each leg being channel-shaped in cross-sectional form and having one end laterally bent to provide an offset tang, the flanges of said tang being inbent and then flattened to provide a retention seat therebetween, the tangs fitting into the respective loops and said detents projecting into said seats.
