ABSTRACT:
I. BACKGROUND OF THE INVENTION
The present invention relates to that of a new and improved garden tool, and specifically relates to a tool which would allow a user to plow a furrow into the ground, while at the same time, laying a length of tubing, electrical wire, hose, or cable.
II. DESCRIPTION OF THE PRIOR ART
U.S. Pat. No. 5,765,648, issued to Sheehan et al., discloses a multipurpose garden tool and method for indoor or outdoor gardening, planting, and soil working.
U.S. Pat. No. 5,752,285, issued to Bendheim et al., discloses a hand-held, multipurpose implement including a handle provided with a resealable storage container and an adapter head having at least a pair of insert receiving sockets.
U.S. Pat. No. 5,695,011, issued to Daniels, discloses a multipurpose worksaving and ergonomically designed gardening tool useful for transplanting seedlings and other gardening tasks.
U.S. Pat. No. 5,103,520, issued to Mazzo, discloses a multi-purpose tool, partly foldable, useful as a hammer/pick, probe/ruler, knife/saw, spade/trowel, and even as a bottle opener.
U.S. Pat. No. 4,565,398, issued to Poulin, discloses a compound type or agricultural tool having a handle which is adapted to be fitted to a blade type of implement which is angularly adjustable for use as a spade, shovel, or hoe and a fork type implement which is similarly adjustable.
U.S. Pat. No. 3,804,450, issued to Guenzel, discloses a multipurpose yard and gardening hand tool having a flat bottomed spade or scoop member and an elongated multiple grip handle having a pointed end.
III. SUMMARY OF THE INVENTION
The present invention is that of an innovative tool for use in a garden or on tilled earth. The present invention would allow a user to furrow into the dirt or ground, while at the same time, laying a length of tubing, electrical wire, hose, or cable into the bottom of the furrow as the blade would be pulled along. The present invention would have a comfortably angled handle with an incorporated channel running from the top of the handle to the rear of the blade assembly, allowing a small diameter tube or cable to feed through the present invention and into the newly formed furrow as the present invention would be pulled along the ground. The front edge of the blade assembly of the present invention would be tapered and have a sharp point to assist with cutting through loose dirt and/or gravel, and the handle would be knurled to prevent a user's hand from slipping while using the present invention.
The present invention would also include a holding stake, which would be used to secure an end of the tubing, wire, hose, or cable at the beginning of the insertion process. Use of the present invention would provide a means for quickly and easily installing a small diameter tube, wire, hose, or cable into the ground without the need to dig a large ditch. The present invention would allow a user to effectively place a length of tubing, wire, hose, or cable at a uniform depth with very little damage to the cable while creating a minimal disturbance to the surface of the ground.
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 appended hereto.
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 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 for carrying out the several purposes of the present invention. It is important, therefore, that the claims be regard as including such equivalent constructions insofar as they do not depart from the spirit and scope of the present invention.
It is therefore an object of the present invention to provide a new and improved tubing or cable installing apparatus which has all of the advantages of the prior art installing apparatus and none of the disadvantages.
It is another object of the present invention to provide a new and improved tubing or cable installing apparatus which may be easily and efficiently manufactured and marketed.
It is another object of the present invention to provide a new and improved tubing or cable installing apparatus which is of durable and reliable construction.
It is yet another object of the present invention to provide a new and improved tubing or cable installing apparatus which is economically affordable and available to the buying public.
It is still yet another object of the present invention to provide a new and improved tubing or cable installing apparatus which is lightweight and easy to use.
It is yet another object of the present invention to provide a new and improved tubing or cable installing apparatus which causes minimum damage and disruption to the ground while being used.
Other objects, features and advantages of the present invention will become more readily apparent from the following detailed description of the preferred embodiment when considered with the attached drawings and appended claims.
