ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a self-powered device for wearing on the back and for cutting foliage. More particularly, the present invention relates to an improved self-powered device for wearing on the back and for use by right and left handed operators in cutting foliage.
2. Description of the Prior Art
A prior art self-powered device
10
for wearing on the back
12
and for cutting foliage
14
is taught by my U.S. Pat. No. 6,122,830.
The general configuration of the prior art self-powered device
10
can best be seen in
FIGS. 1-4
, and as such, will be discussed with reference thereto.
The prior art self-powered device
10
has a backpack portion
16
with a frame
18
that has a vertical back-engaging portion
19
and a horizontal platform
21
extending rearwardly from the vertical back-engaging portion
19
thereof, a gas engine
20
attached to the horizontal platform
21
of the frame
18
, a harness
23
attached to the frame
18
and having a pair of shoulder straps
25
, and a foliage cutting portion
24
operatively connected to the gas engine
20
.
SUMMARY OF THE INVENTION
ACCORDINGLY, AN OBJECT of the present invention is to provide an improved self-powered device for wearing on the back and for use by right and left handed operators in cutting foliage that avoids the disadvantages of the prior art.
ANOTHER OBJECT of the present invention is to provide an improved self-powered device for wearing on the back and for use by right and left handed operators in cutting foliage that is simple and inexpensive to manufacture.
STILL ANOTHER OBJECT of the present invention is to provide an improved self-powered device for wearing on the back and for use by right and left handed operators in cutting foliage that is simple to use.
BRIEFLY STATED, STILL YET ANOTHER OBJECT of the present invention is to provide an improved self-powered device for wearing on the back and for use by right and left handed operators in cutting foliage of the type having a backpack portion, a gas engine attached to the backpack portion, and a foliage cutting portion operatively connected to the gas engine. The improvement includes the gas engine being swively attached to the backpack portion so as to allow the gas engine to rotate from one side to the other relative to the backpack portion for allowing use by the right and left handed operators and so as to allow the foliage cutting portion to move forwards and backwards relative to the backpack portion without the right and left handed operators having to move relative to the foliage which would be required if the gas engine was rigidly attached to the backpack portion.
The novel features which are considered characteristic of the present invention are set forth in the appended claims. The invention itself, however, both as to its construction and its method of operation, together with additional objects and advantages thereof, will be best understood from the following description of the specific embodiments when read and understood in connection with the accompanying drawing.
