ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a lightweight lawn trimmer, mower and edger system and more particularly pertains to facilitating the safe and convenient cutting of grass, trimming, and edging of soil.
2. Description of the Prior Art
The use of cutting and edging systems of known designs and configurations is known in the prior art. More specifically, cutting and edging systems of known designs and configurations previously devised and utilized for the purpose of cutting and edging through known methods and apparatuses are known to consist basically of familiar, expected, and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which has been developed for the fulfillment of countless objectives and requirements.

While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not describe a lightweight trimmer, lawn mower and edger system that allows facilitating the safe and convenient cutting of grass, trimming, and edging of soil.
In this respect, the lightweight trimmer, lawn mower and edger system according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in doing so provides an apparatus primarily developed for the purpose of facilitating the safe and convenient cutting of grass, trimming, and edging of soil.
Therefore, it can be appreciated that there exists a continuing need for a new and improved lightweight lawn mower, trimmer, and edger system which can be used for facilitating the safe and convenient cutting of grass, trimming, and edging of soil. In this regard, the present invention substantially fulfills this need.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known types of cutting, trimming, and edging systems of known designs and configurations now present in the prior art, the present invention provides an improved lightweight lawn mower, trimmer, and edger system. As such, the general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new and improved lightweight lawn mower, trimmer, and edger system and method which has all the advantages of the prior art and none of the disadvantages.
To attain this, the present invention essentially comprises an aluminum cylindrical support bar. The support bar has an upper end and a lower end.
A molded plastic power grip is provided. The grip is coupled to the upper end of the support bar. The grip is formed in a cylindrical configuration. The grip has a bend and a gripping portion. The grip has a variable power controlling trigger and an associated trigger guard. The trigger further has a power source input in the form of an electrical receptacle.
A molded plastic support handle is provided next. The support handle is coupled to an intermediate portion of the support bar adjacent to the lower end of the grip. The support handle has an angle adjusting nut. The support handle is adapted to allow the user to comfortably hold the system in a safe and secure manner.
Provided next is a molded plastic motor housing. The motor housing is formed in a cylindrical configuration. The motor housing has a bent bulbous end. The motor housing has a linear end. The linear end is coupled to the lower end of the support bar.
A motor is provided. The motor is housed in the bulbous end of the motor housing. The motor has a rotatable drive shaft. The motor has a pair of braided stainless steel wires. The wires extend oppositely from each other from the drive shaft. The wires are rotatable in a primary plane parallel with a plane of the grass to be mowed or trimmed. The wires alternately are rotatable in a secondary plane perpendicular to the primary plane and parallel with a plane of the soil to be edged.
Also provided is a molded plastic disc-shaped protective deck. The deck has a top face and a bottom face. The deck further has a front, a back and a pair of sides. The top face is coupled to the bulbous end of the motor housing. The deck has a central cylindrical aperture. The drive shaft extends through the aperture. A lip is provided around the periphery of the deck. The lip extends downwardly. A flap is provided. The flap is comprised of an arc of the front of the deck. The flap has a pivot end, an arced end and a pair of side edges. The flap further has a pair of hinges. The hinges couple the pivot end of the housing to an adjacent portion of the deck. A latch is provided. The latch is coupled to the deck. The latch is adapted to hold the flap down when operating to cut grass. The flap is adapted to pivot upwardly 90 degrees. In this manner the wires are exposed when operating to trim grass or edge soil.
A pair of riding wheels is provided. The riding wheels are coupled to the bottom face of the deck adjacent to the pivot end of the flap. The riding wheels are adapted to ride on a top surface of grass when edging soil.
A pair of guard wheels is provided. The guard wheels are coupled to the lip of the deck adjacent to the flap. The guard wheels are adapted to ride on a side face of soil when edging soil.
The system thus has three sets of wheels, caster wheels which are rotatable about a primary axes A when cutting grass or trimming and wherein the primary axes are in a plane parallel with grass to be cut or trimmed, and riding wheels rotatable about parallel secondary axes B which are perpendicular to the primary axes A, and guard wheels rotatable about parallel tertiary axes C which are perpendicular to the secondary axes.
A pair of slots are provided. The slots are provided on the sides of the deck. A locking edge is associated with each slot.
A pair of stabilizing beams is provided. Each stabilizing beam has an upper end and a lower end. The upper ends are coupled to the motor housing adjacent to the lower end of the support bar. The lower ends are coupled to the sides of the deck.
Further provided is a pair of caster wheels. Each castor wheel has an associated L-shaped flange. A horizontal portion is coupled to a castor wheel. A vertical portion has retention bumps. The bumps are adapted to removably couple within the slots on the side end of the protective housing. The wheels are employed when the flap is down and grass is being cut or trimmed. The wheels may be removed when the flap is up and soil is being edged.
Provided last, for optional use, is a bag for collecting cut grass clippings. The bag has a lower end. The lower end is coupled to the rear end of the deck at an aperture. The bag has an upper end. The upper end is coupled to the support handle.
There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood and in order that the present contribution to the art may be better appreciated. There are, of course, additional features of the invention that will be described hereinafter and which will form the subject matter of the claims attached.
In this respect, before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and to the arrangements of the components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced and carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein are for the purpose of descriptions and should not be regarded as limiting.
As such, those skilled in the art will appreciate that the conception, upon which this disclosure is based, may readily be utilized as a basis for the designing of other structures, methods and systems
