Abstract
Abstract An improved self-locking bundling strap comprising, in one form, a plurality of pairs of spaced, generally transverse narrow slits of predetermined length extending from the edges of the strap inwardly towards the center of the width of the strap, each pair being separated by a selectively proportioned center portion, to facilitate the severance of an excess portion thereof by rotatably twisting said portion while substantially preserving the initial strap strength and flexibility. Other embodiments include obliquely angled slits having either a straight or curvilinear contour.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
217 words
In a bundling strap of the type having a head end portion having a transverse aperture therethrough, a tail end portion, an elongated body portion therebetween having a first surface, a second surface, a first side and a second side, and proportioned to be received within said head end portion transverse aperture, and engaging means in said head end portion for stepless coacting engagement with at least one of said first and second surfaces of said body portion, the improvement comprising: said body portion having at least one pair of slits for enhancing the severance of a selective length of said body portion from the remainder thereof, each slit of a pair thereof extending inwardly, respectively, from an opposite one of said body portion first and second sides a predetermined distance towards the center of the width of said body portion providing a central portion thereat, each of said slits further extending between and communicating with said body portion first and second surfaces, each of said slits being generally curvilinear and forming generally arcuate segments adjacent said first and said second sides of said body portion and extending longitudinally slightly beyond said body portion central portion thereby providing a partial shield about said central portion upon the severance of said body portion intermediate said pair of slits.
Claim 2
Dependent Claim
217 words
In a bundling strap of the type having a head end portion having a transverse aperture therethrough, a tail end portion, an elongated body portion therebetween having a first surface, a second surface, a first side and a second side, and proportioned to be received within said head end portion transverse aperture, and engaging means in said head end portion for stepless coacting engagement with at least one of said first and second surfaces of said body portion, the improvement comprising: said body portion having at least one pair of slits for enhancing the severance of a selective length of said body portion from the remainder thereof, each slit of a pair thereof extending inwardly, respectively, from an opposite one of said body portion first and second sides a predetermined distance towards the center of the width of said body portion providing a central portion thereat, each of said slits further extending between and communicating with said body portion first and second surfaces, each of said slits being generally curvilinear and forming generally arcuate segments adjacent said first and said second sides of said body portion and extending longitudinally slightly beyond said body portion central portion thereby providing a partial shield about said central portion upon the severance of said body portion intermediate said pair of slits.
Claim 3
Dependent Claim
248 words
In a bundling strap of the type having a head end portion having a transverse aperture therethrough, a tail end portion, an elongated body portion therebetween having a first surface, a second surface, a first side and a second side, and proportioned to be received within said head end portion transverse aperture, and engaging means in said head end portion for stepless coacting engagement with at least one of said first and second surfaces of said body portion, the improvement comprising: said body portion having at least one pair of slits for enhancing the severance of a selective length of said body portion from the remainder thereat, each slit of a pair thereof extending inwardly, respectively, from an opposite one of said body portion first and second sides a predetermined distance towards the center of the width of said body portion, each of said slits further extending between and communicating with said body portion first and second surfaces, each of said slits communicating with said body portion first surface along a first predetermined length, and communicating with said body portion second surface along a second predetermined length different than said first predetermined length, wherein the area of said body portion intermediate said pair of opposingly disposed slits has a cross-section generally defining an isosceles trapezoid providing a greater surface area and resistance to coplanar deflection at the one of said body porTion first and second surfaces adjoining the longer of the parallel sides defining said isosceles trapezoidal area.
Claim 4
Dependent Claim
248 words
In a bundling strap of the type having a head end portion having a transverse aperture therethrough, a tail end portion, an elongated body portion therebetween having a first surface, a second surface, a first side and a second side, and proportioned to be received within said head end portion transverse aperture, and engaging means in said head end portion for stepless coacting engagement with at least one of said first and second surfaces of said body portion, the improvement comprising: said body portion having at least one pair of slits for enhancing the severance of a selective length of said body portion from the remainder thereat, each slit of a pair thereof extending inwardly, respectively, from an opposite one of said body portion first and second sides a predetermined distance towards the center of the width of said body portion, each of said slits further extending between and communicating with said body portion first and second surfaces, each of said slits communicating with said body portion first surface along a first predetermined length, and communicating with said body portion second surface along a second predetermined length different than said first predetermined length, wherein the area of said body portion intermediate said pair of opposingly disposed slits has a cross-section generally defining an isosceles trapezoid providing a greater surface area and resistance to coplanar deflection at the one of said body porTion first and second surfaces adjoining the longer of the parallel sides defining said isosceles trapezoidal area.
Claim 5
Dependent Claim
19 words
The improvement as defined in claim 2, wherein said first predetermined length is shorter than said second predetermined length.
Claim 6
Dependent Claim
19 words

Claim 8
Dependent Claim
35 words
The improvement as defined in claim 2 wherein said isosceles trapezoidal area comprises at least about 50 percent of the cross-sectional area of said body portion as measured generally transverse to the longitudinal axis thereof.
Claim 9
Dependent Claim
41 words
The improvement as defined in claim 2 wherein said isosceles trapezodial area is in the range of about 50 percent to about 95 percent of the cross-sectional area of said body portion as measured generally transverse to the longitudinal axis thereof.
Claim 10
Dependent Claim
28 words
The improvement as defined in claim 2, wherein said body portion comprises a plurality of said pairs of slits longitudinally disposed along the length of said body portion.
Claim 11
Dependent Claim
