A bag holder is formed from components that are molded or extruded from engineering plastics and that are assembled by slip fit arrangements without using any fasteners. The holder includes a sectional standard attached by a multi-apertured base block to supporting legs adapted to rest on any flat surface. A multi-apertured head block serves to attach a split circular bag holder portion to the standard. Spring clips are adjustably positioned on the circular portion so as to fasten the open upper end of a bag thereon.

Field Of The Invention:
The present invention generally appertains to improvements in supporting devices for receptacles and more particularly relates to new and novel improvements in holders for trash, grass, and leaf bags and the like flexible containers or receptacles.
2. State Of The Art:
Considerable activity has always been present in developing various and sundry types of bag holders. In the patented art, there are early patents, such as US. Pat. No. 148,702, issued Mar. 17, 1874, and there are more recently issued patents, such as US. Pat. No. 3,532,314, granted Oct. 6, 1970.
While all of the patented and otherwise known bag holders reliably function in the intended manner for supporting a bag with its upper end portion open and ready to receive articles to be placed therein, the known bag holders have serious drawbacks.
There is the matter of their costly design. Additionally, the known holders are not of a complete knockdown ty'pe, whereby they can be compactly and easily packaged and economically shipped and sold in such packaged state. Furthermore, such holders, which are of a knock-down type, require fastening means for assembling them in erected condition and such fastening means dictate the need for tools and require the expenditure of considerable assembly time.
SUMMARY OF THE INVENTION The primary object of the present invention is to provide a holder that is formed of components which can be economically constructed and easily packaged in a knock-down state for shipping and which can be assembled together in a minimum of time without requiring any fastening means or the use of any assembling tools.
Another object of the present invention is to provide a bag holder that is formed of components of light weight and durable material, such as engineering plastics, which can be molded or extruded and which do not require any costly machine work. Such materials will be impervious to the elements and will not warp, rust or oxidize.
Generally considered, the bag holder is composed of a ground supported stand made up of a sectional vertical standard that is attached at its lower end to a base block from which supporting legs radially project in angularly spaced apart arrangement. The standard and legs are formed from tubular stock and have their ends frictionally fitted in appropriate bores in the base block.
The upper end of the standard is attached to a head block from which a tubular holder portion of circular form projects in a manner so that it overlies the supporting legs. The head block has a vertical bore in which the upper end of the standard is fitted and also has a pair of parallel, laterally spaced horizontal bores in which the angularly offset ends of a split ring, which constitutes the circular holder portion, are frictionally fitted. The outer ends of the semi-circular portions of the split ring are held together by an internally fitted dowel or plug.
Spring clips are slidably positioned on the ring and have axial slits whereby the upper end of a bag is clamped onto the circular holder portion with the bag hanging down from the circular holder portion and resting on the legs so that the weight of the bag and its contents are imposed on the legs so as to further stabilize the bag holder.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now more particularly to the accompanying drawing, the bag holder, generally designed by reference number 10, includes a supporting stand 12 and a bag holder portion 14, which is attached to and carried in a horizontal position by the upper end of the supporting stand. p a The stand 12 is composed of a vertical sectional standard 16 which has an upper portion 18 and a lower portion 20. Both of such portions'are fabricated from tubular stock of plastics materials.
The lower end 22 of the upper portion 18 is compressed radially so that it is of less diameter than the main body of the upper portion. An upwardly diverging portion 24 connects the end 22 to the main body of the upper portion and provides a tapering shoulder on its outer surface. The upper end 26 of the lower portion 20 is outwardly flared to provide, on its inner surface, an upwardly diverging seat 28 that receives the shoulder 24 with the end 22 being socketed within the upper end of the lower portion 20 below the outwardly flared upper end 26. In this respect, the lower end 22 is of an outer diameter slightly less than the internal diameter of the tubular portions 18 and 20 and is of such diameter that it is snugly socketed within the lower portion 20, as shown in FIG. 6. v
A connecting base block 30 of plastics materials is provided for attaching the standard 16 to tubular supporting legs 32 of plastics materials, as shown in FIGS. 1 and 7. The base block has a square lower portion 34 and an integral pyramidal shaped upper portion 36.
The upper portion 36, as shown in Flg. 7, has a vertical bore 38 formed therein to accommodate the lower end 40 of the bottom portion 20 of the standard. The
square lower portion 34 of the block is provided on, at
least three of its faces, with radial bores 42 that pass through such faces, so that the bores are arranged at right angles and are spaced 90 apart. The inner ends 4 polymers.
lt is believed obvious from the foregoing description,
taken in conjunction with the accompanying drawing as to the manner in which the components are joined together. In their disassembled relationship, it will be appreciated that all of the components can be placed in a compact side by side arrangement for easy and 44 of the tubular rods 32, which define the stabilizing The bag holder portion 14 is composed of a split cir cular ring 50 formed from tubular 'stock of plastics materials. The ring is composed of complemental semicircular sections 52 and 54 which have outer open ends within which a plug 56, as shown in FIG. 5, is adapted to be frictionally fitted so as to connect the outer ends of the split sections 52 and 54 of the ring together in tight abutting relation. The split ring sections 52 and 54 have integral anchoring fingers 58 formed on their inner ends, with the fingers being formed by being bent away from the sections and disposed at a 90 angle to the assembled circular ring 50. The fingers are disposed in spaced apart parallel relation coplanar with the ring. They are adapted to be frictionally seated in bores 6i) and 62 formed through the front face of a head block 64 of plastics materials. The block 64 has a lower pyradimal portion 68 which is formed with a vertical bore 70 within which the upper end 72 of the upper standard portion 18 is frictionally fitted, as shown in FIG. 2.
Means is provided for attaching the upper open end portion 72 of a collapsible trash bag 74 or the like to small packaging. The components can be joined together in a matter of minutes without the use of any tools.
While the best known form of the present invention has been described herein and illustrated in the drawing, it is obvious that such is merely one embodiment of the invention which is defined by the spirit and scope of the appended claims.
