Method for installing irrigation drip line couplers

Abstract

A method for utilizing a tool for installing drip tubes to main drip lines with a coupler. The tool may have an integral body which serves several functions in installing drip tubes to main drip lines with a coupler. The tool has a needle which punctures holes in the main drip line for insertion of one end of the coupler. The tool has a slotted head which grasps the coupler facilitating the insertion of the coupler into the hole in the main line. Embodiments of the tool may also have apertures in the tool which fit around the coupler for facilitating the insertion of an end of the coupler into the open end of the drip tube.

DETAILED DESCRIPTION OF THE EMBODIMENTS

(9) Referring specifically to the figures, FIG. 1 depicts a configuration of a drip line 10, a drip line coupler 12, and a segment of the main drip line 14. For this type of irrigation system, water is conveyed via the main drip line 14 through the drip line 10 and is dispersed at the opposite end of the drip line through a dispersal device, such as an emitter, not shown. The drip line 10 is connected to the main drip line 14 by a drip line coupler 12, such as that depicted in FIG. 1. Embodiments of typical drip line couplers 12 have a first male end 16 which is inserted into the main drip line 14 through a hole or aperture 20. The drip line coupler 12 has a second male end 18 for insertion into an end 22 of the irrigation drip line 10. Embodiments of the drip line coupler 12 have an enlarged diameter section intermediate of the first male end 16 and the second male end 18, such as shoulder member 24, which has an external diameter D which is larger than the diameters of the first male end 16 and the second male end 18. The first male end 16 and the second male end 18 may be identical, such that either end may be inserted into either the drip line 10 or the main drip line 14. Each end of the coupler 12 will typically have a conical configuration, where the diameter progressively gets larger from the end of the coupler to the end of the conical section.

(10) FIG. 2 shows an embodiment of the disclosed tool 100 for installing irrigation drip line couplers 12 into the main drip line 14. Embodiments of the disclosed tool 100 may comprise an integral body comprising a handle member 102, an intermediate section 104, and a head member 106. As depicted in the figures, the handle member 102 and the intermediate section 104, when considered without the head member 106, may comprise a T configuration, with the handle member being the cross-member and the intermediate section 104 forming the vertical member. In other words, handle member 102 defines a first planar surface P.sub.1 which is approximately perpendicular to a second planar surface P.sub.2 defined by the intermediate section 104. Intermediate section 104 has a central axis L.sub.2 which is at the approximate longitudinal center of the intermediate section.

(11) Likewise, the intermediate section 104 and the head member 106, when considered without the handle member 102, may comprise a J. Head member 106 may comprise a U configuration comprising a first leg 108 and a second leg 110 with a slot 112 defined between the first leg and the second leg. As depicted in the figures, first leg 108 and second leg 110 extend outwardly and define a plane P.sub.3 which is generally perpendicular to the plane P.sub.1 defined by intermediate section 104. First leg 108 and second leg 110 each have a length, which may, for the two legs, be equivalent.

(12) The disclosed tool 100 further comprises a needle member 114 which also extends outwardly from the intermediate section 104. As shown in the figures, the needle member 114 is generally parallel and adjacent to one of the leg members, such as first leg 108 shown in the figures. Needle member 114 typically has a length less than the length of the leg to which it is adjacent. It is to be appreciated that in this configuration, the needle member 114 does not interfere with a drip line coupler 12 which may be fitted within slot 112. In addition, because needle member 114 is adjacent to one of the legsfirst leg 108 in this caseand has a shorter length, the leg acts to prevent the needle member 114 from inadvertently poking someone in the hand or making a hole in the person's pocket. The needle member 114 defines a long axis L.sub.3 which is parallel to plane P.sub.3. The long axis L.sub.3 of needle member 114 is offset from central axis L.sub.2 at the center of intermediate section 104.

(13) Embodiments of the tool 100 may also comprise apertures 120 and 122 in the intermediate section 104 where the axis of each aperture is perpendicular to the second planar surface P.sub.2. These apertures 120, 122 have diameters which are sized to be smaller than the enlarged diameter section of the coupler, such as shoulder 24. The proper size aperture 120, 122 may thereafter be utilized, as illustrated in FIG. 7, to install second male end 18 into drip line 10. Embodiments of the tool 100 may also have aperture 124 in handle member 102 which may be utilized for placement of a lanyard or other device for securing the tool.

(14) FIGS. 6-8 illustrate the various operations which may be performed with embodiments of the tool. FIG. 6 shows an embodiment of the device 100 being utilized to puncture a hole in main drip line 14. FIG. 7 shows an embodiment of the device 100 being utilized to insert second male end 18 into an open end of drip line 10. FIG. 8 shows an embodiment of the tool 100 in which a coupler 12 has been inserted into slot 112 such that shoulder 24 is between head 106 and main drip line 14, such that pressure against handle member 102 pushes coupler 12 into the previously created hole in main drip line 14.

(15) Embodiments of the disclosed tool may be fashioned from either metallic or high impact plastic materials.

(16) While the above is a description of various embodiments of the present invention, further modifications may be employed without departing from the spirit and scope of the present invention. Thus the scope of the invention should not be limited according to these factors, but according to the following appended claims.
