BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to the field of support frameworks for flexible bags in general, and in particular to a collapsible wheeled framework that functions as a flexible bag carrier.
2. Description of Related Art
As can be seen by reference to the following U.S. Pat. Nos. 4,976,406; 5,360,189; 5,775,649 and 6,076,782, the prior art is replete with myriad and diverse flexible bag support frameworks.
While all of the aforementioned prior art constructions are more than adequate for the basic purpose and function for which they have been specifically designed, they are uniformly deficient with respect to their failure to provide a simple, efficient, and practical arrangement wherein a flexible bag may be releasably secured to a collapsible wheeled framework that can be easily transported from one location to another.
As most gardeners, lawn maintenance workers and homeowners having lawns with trees are all too well aware, their routine chores are often compounded by the need to constantly move a flexible bag collection receptacle from one location to another which often results in the tearing or rupturing of the collection receptacle
As a consequence of the foregoing situation, there has existed a long standing need for a new and improved flexible bag support and transport device that will releasably engage a flexible bag in a secure manner while being capable of wheeled transport and a collapsed slim profile during storage, and the provision of such an arrangement is the stated objective of the present invention.
BRIEF SUMMARY OF THE INVENTION
Briefly stated, the collapsible wheeled flexible bag carrier that forms the basis of the present invention comprises in general a collapsible wheeled framework unit, a plurality of flexible bag securing units and a towing unit.
As will be explained in greater detail further on in the specification, the wheeled collapsible framework unit includes a pair of inverted generally U-shaped support members each having hollow support legs provided with wheel assemblies and a cross piece that a portion of the open mouth of a flexible bag can be draped over to support the flexible bag on the framework unit in a conventional fashion when the support members are pivoted away from one another.
In addition, the towing unit includes a tow rope member having opposite ends adapted to be secured to the lower end of one of the support members to maintain the support members in a pivoted open orientation during transport; and, the plurality of flexible bag securing units each includes a tethered spring loaded clamp member having a pair of jaw elements each provided with semi-cylindrical extensions that will increase the surface area gripping contact between the individual clamp members, the upper portions of the flexible bag and a selected one of the cross piece on the support members.
