Abstract
Apparatus for providing a six-inch deep trench in a lawn surface, for the primary purpose of installing irrigation pipe for sprinkler systems. A trenching tool which includes a lower portion having two heavy steel blades and a hinge mechanism. The steel impact blades are sharpened at the bottom to accommodate a V configuration to enhance the downward penetrating action by the operator as he drives the blades into the ground until the desired 6" is reached. The operator then forces the handles together which separates or widens the bottom portion of the channel. The channel/trench is elongated for any distance the operator desires by repeatedly thrusting the tool into the lawn right next to the elongated section of the original opened trench.
Description
Manual Trench Tool FIELD OF THE INVENTION
The present invention relates to a trenching tool which is manoeuvred by hand into soft soils, for the purpose of installing sprinkler systems, with minimum damage to present lawn surfaces.
BACKGROUND
The lawn sprinkler systems in North Americav are expected to be one of the growing desires of the aging baby boomers. 'This growing segment of the populace has a very restricted budget. They also have in most cases, matured homes with established lawns. For these reasons it is predicted that the time is right for the introduction of a light duty manual trenching tool for the trenching part of shallow sprinkler system pipes.
There are very few previous tools offered for this simple trenching operation.
S~~Y
It is the object of the present invention, therefore, to provide an improved lightweight tool to open the ground temporarily, approximately 6 inches deep for lengths of a normal urban property plot.
In the principle aspect of their invention there is provided a manual trench tool comprising of the following:
(I) - (1) two handles (1) and (2) comprising an elongated length of wall pipe material two plates (3) at the bottom of the assembly which are angle sharpened for maximum penetration - hinges fabricated from strong standard pipe (4) with a bolt (5) supplementing the hinge pin One embodiment of the invention will now bE; described in conjLmction with the drawings in which:
BRIEF DESCRIPTION OF THE DRAWINGS
Figure #1 is a side view of the present Invention showing the thrust position Figure #2 is a side view showing the tool in the trench widening position Figure #3 is the angle view of the Manual Trench Tool DETAILED DESCRIPTION
Referring to the accompanying drawings there is illustrated a manual trench tool, generally indicated by preference numeral (8). The tool (8) is particularly useful for providing a temporary trench (9) for inserting shallow lawn sprinkler lines for lawn sprinklers.

BRIEF DESCRIPTION OF THE DRAWINGS
Figure #1 is a side view of the present Invention showing the thrust position Figure #2 is a side view showing the tool in the trench widening position Figure #3 is the angle view of the Manual Trench Tool DETAILED DESCRIPTION
Referring to the accompanying drawings there is illustrated a manual trench tool, generally indicated by preference numeral (8). The tool (8) is particularly useful for providing a temporary trench (9) for inserting shallow lawn sprinkler lines for lawn sprinklers.
(2) The tool (8) is fabricated from various grades of standard steel. The handles (1) and (2) are cut from standard 1" and 1/8" wall pipe. The two plates (3) at the bottom of the tool are cut to size from '/4" standard steel plate. The hinges (4) and (5) are cut and fabricated from 3/4" pipe (4) and 5/8" bolt (5). This tool has to be durable enough only to penetrate the lawn surface (6) and (7) to a depth of 6". This process is simplified significantly by the softening of the lawn surface (6) by water before the trench (9) is started.
The handles (1) and (2) are bent to a desired angle 30 degrees approximately 30% of the distance from the top. The left handle must be bent 30 degrees to the left, whereas, the right handle (2) must be bent 30 degrees to the right. These handles are welded to the 1/4" steel plates (3a) and (3b) are sharpened on the outside of the bottom of the plates to allow the two plates to form a perfect V at the bottom of the tool, as shown in Figure # 1.
This allows for ease of penetration in the lawn surface. The hinges, mentioned above, are positioned at approximately the centre of the elongated portion of the steel plates, being of transmission snap-ring plier type are such that the centre portions of the hinge are on the same side of the centre longitudinal axis, as their particular strike plates. They are fastened by a welded process. The handles are offset so the manual operator may force the handles together causing a widening of the plates at the bottom. See Figure # 2.
The handles (1) and (2) are bent to a desired angle 30 degrees approximately 30% of the distance from the top. The left handle must be bent 30 degrees to the left, whereas, the right handle (2) must be bent 30 degrees to the right. These handles are welded to the 1/4" steel plates (3a) and (3b) are sharpened on the outside of the bottom of the plates to allow the two plates to form a perfect V at the bottom of the tool, as shown in Figure # 1.

They are fastened by a welded process. The handles are offset so the manual operator may force the handles together causing a widening of the plates at the bottom. See Figure # 2.
The widening action of the lower portion of the plates forces the lawn materials to open therefore create a six-inch long trench (9) six inches deep. The operator then withdraws the apparatus from the lawn (6) and (7), and therefore returns the handles to the original V configuration. He then thrusts the tool into the lawn again, obviously right ~;lext to the original six inches of trench. Through repeated simultaneous actions the operator can create several six-inch deep trenches wherever he wants, in his lawn.
Obviously the irrigation pipe gets laid in these trenches to the desired locations far sprinkler heads to be installed later. The trench is filled in by simply pushing down on each side of the lawn edge. by the operator's foot.
The apparatus eliminates the need for costly equipment usually required to do this procedure. This apparatus also eliminates the damage done to a lawn's surface by the heavy equipment required.
Since various modifications could be made irz my invention as herein above described, and many apparently widely different embodiments of same made within the spirit and scope of the claim; without department from such spirit and scope, it is intended that all matter contained in the accompanying specification shall be interpreted as illustrated only and not in a lilnitillg sense.

Claims
Claims:
I claim, - a manual trenching tool comprising two steel plates each plate having a length, a height and a sharpened edge along with a length of said plate; said plates are hinged together by hinge means for rotation about a horizontal axis parallel to said sharpened edge, approximately midway the plates height; and two handles, each handle fixed to a corresponding plate away from said sharpened edge, each handle is further bent in a direction away from the plates such that after the plates are made to penetrate the ground, the handles are forced towards each other, causing the plates to widen in an area close to the sharpened edges and thereby creating a trench.
