Leaf removal system

Abstract

A leaf removal system of the blower-vac type is disclosed which allows the user to minimize down-time during the process of leaf and debris removal. The user can work productively removing leaves and other debris for a longer time before needing to empty or replace the debris bag.

Description

FIELD OF THE INVENTION[0001]The present invention relates to the field of leaf removal systems of the leaf blower-vacuum type.BACKGROUND OF THE INVENTION[0002]Leaf blowing systems of the general type described herein are known.[0003]Leaf blowers have been controversial since they were introduced in 1976 to address a drought in California. The City of Los Angeles mandated their use to prevent gardeners from using water to clean walks and driveways. This was due to the highly cost-effectiveness of a leaf blower. City maintenance crews, professional gardeners, and home owners have all defended blowers to protect their pocketbooks.[0004]Hand-held blower-vacs are blowers that can work in reverse and suck leaves and debris into a bag that the user can carry to a compost pile or other suitable disposal place. These machines are generally quieter, especially the ones powered by electric motors.[0005]Hand-held blower-vacs are useful for a variety of tasks. Gathering and shredding leaves is o...

AI Technical Summary

Benefits of technology

"The present invention is a leaf removal system that allows users to minimize down-time during the process of leaf and debris removal. The system includes a debris bag connected to a blower-vac, a bag transport, and an attachment system that removably attaches the debris bag to the bag transport. The system may also include a debris reduction impeller within the blower-vac. The debris bag traps most of the debris while allowing air to escape, and the material used for the bag can include mosquito netting, landscape fabric, or commercial weed barrier. The invention reduces the number of times the debris bag requires emptying or replacing, improves the ability to store small twigs, transport a heavy bag of debris, and can be made disposable or reusable. It is easy to use and can be made of readily available materials."

Problems solved by technology

This was due to the highly cost-effectiveness of a leaf blower.

However, a blower like this would be good for clearing out cracks in the driveway because of the high pressure but it would perform poorly blowing leaves in a yard.

While such a small opening would increase pressure, i.e., miles per hour, the result would be a dramatic loss in air volume.

A blower so configured might work well sweeping dust and sand off a driveway but without sufficient pressure, it would have a difficult time moving anything other than the lightest debris.

One problem with conventional blower-vacs is the frequency with which the bag must be emptied or replaced, either due to the bag becoming full or due to the bag becoming too heavy to transport.

Other problems exist.
