Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
138 words
Plastic strapping for passing around electrical conductors and the like and tying such conductors in a bundle using a separate locking device, such strapping consisting of; an elongated extruded plastic tape substantially longer than that portion thereof used for tying the bundle of conductors, the tape being of electrically insulating material generally rectangular in section having a width about three times the thickness and with rounded corners, and a plurality of parallel longitudinally extending ribs on one surface of the width of the tape and extending throughout the entire length of the tape, the ribs having a height small in relation to the thickness of the tape, a pointed edge on each of the ribs defined by rib sides, the ribs positioned to lie parallel to one another and approximately equally spaced across the width of the tape.
Claim 2
Dependent Claim
138 words
Plastic strapping for passing around electrical conductors and the like and tying such conductors in a bundle using a separate locking device, such strapping consisting of; an elongated extruded plastic tape substantially longer than that portion thereof used for tying the bundle of conductors, the tape being of electrically insulating material generally rectangular in section having a width about three times the thickness and with rounded corners, and a plurality of parallel longitudinally extending ribs on one surface of the width of the tape and extending throughout the entire length of the tape, the ribs having a height small in relation to the thickness of the tape, a pointed edge on each of the ribs defined by rib sides, the ribs positioned to lie parallel to one another and approximately equally spaced across the width of the tape.
Claim 3
Dependent Claim
28 words
Plastic strapping as in claim 1 wherein there are three identical ribs lying parallel to one another at about one-fourth, one-half and three-fourths the width of the tape.
Claim 4
Dependent Claim
42 words
Plastic strapping as in claim 2 wherein the height of the ribs is about one-fifth to one-sixth the thickness of the tape and the pointed edge is defined by the sides of the ribs merging at an included angle of about 60*.
