ABSTRACT:
BACKGROUND AND OBJECTS OF THE INVENTION
The present invention is generally related to collection devices and methods and, in particular, to a system and method for collecting leaves.
As is known in the art, leaves and other yard debris are traditionally collected and placed in bags for appropriate disposal.
This becomes something of a difficult and time-consuming operation especially for one person.
Various bag holders and supports have been used in the art. However, such have proven to be costly to manufacture and difficult to use in practice.
Accordingly, it is an object of the present invention to show a collection/storage device for leaves which may be easily used by one person.
It is also an object of the invention to demonstrate a collection and storage device which may be economically manufactured for widespread commercial appeal.
It is a further object of the invention set forth a novel bag subcombination which may be effectively used in combination with the leaf collection system described and for other uses as well.
These and other objects and advantages of the present invention will be appreciated by those of skill in the art from the description and drawings which follow.
SUMMARY OF THE INVENTION
The invention comprises a combined chute and bag system for various uses including the collection of leaves.
The chute includes a widened and curved intake portion for the efficient intake of articles such as leaves. The chute further includes a rear reinforced element for the attachment of a bag as desired.
A draw-string bag forms part of the system and includes plural perforated openings to permit equalization of air pressure and reduce clinging of the bag walls together.
The bag subcombination, including the use of plural wall openings, has utility for the collection of other items besides leaves.
