Abstract

Abstract Disclosed is a plastic clamping ridged strap which can clampingly hold an object such as an electric wire, onto a plate in cooperation with associated apertures in the plate. The clamping strap according to this invention is composed of an elongated plastic band molded to have a plurality of tall and short ridges arranged alternately with each other in such a way that each tall ridge is nearer to one adjacent short ridge than to the other. The ridged strap can pass the associated aperture of the plate only in one direction by allowing the tall ridges to yieldingly bend down when caught by the opening edge of the associated aperture. The ridged strap, however, cannot pass the associated aperture in the other direction because the short ridge will prevent the tall ridge from bending to a level low enough to allow the ridged strap to pass the aperture.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 129 words
In combination, a ridged plastic clamping strap composed of an elongated plastic band having a plurality of alternately arranged tall flexible ridges and short rigid ridges intergrally connected to one surface of the elongated band, each tall ridge being nearer to one adjacent short ridge than to the other adjacent short ridge, thus leaving a space between the tall ridge and the other adjacent short ridge sufficient to allow the tall ridge to bend down but leaving a space between the tall ridge and the one adjacent short ridge insufficient to allow the tall ridge to bend down; and a plate having at least one aperture which allows the short rigid ridges to pass without obstruction and allows the tall flexible ridges to pass only when yieldingly bent down.
Claim 2
Dependent Claim 129 words
In combination, a ridged plastic clamping strap composed of an elongated plastic band having a plurality of alternately arranged tall flexible ridges and short rigid ridges intergrally connected to one surface of the elongated band, each tall ridge being nearer to one adjacent short ridge than to the other adjacent short ridge, thus leaving a space between the tall ridge and the other adjacent short ridge sufficient to allow the tall ridge to bend down but leaving a space between the tall ridge and the one adjacent short ridge insufficient to allow the tall ridge to bend down; and a plate having at least one aperture which allows the short rigid ridges to pass without obstruction and allows the tall flexible ridges to pass only when yieldingly bent down.
Claim 3
Dependent Claim 25 words
The combination of claim 1, wherein the tall and short ridges are arranged in a direction perpendicular to the longitudinal direction of the ridged strap.
Claim 4
Dependent Claim 36 words
The combination of claim 2, wherein each tall ridge is nearer to the subsequent short ridge than to the precedent short ridge in the opposite longitudinal directions as viewed from the center of the ridged strap.
Claim 5
Dependent Claim 25 words
The combination of claim 1, wherein the tall and short ridges are inclined to the direction perpendicular to the longitudinal direction of the ridged strap.
Claim 6
Dependent Claim 36 words
The combination of claim 4, wherein each tall ridge is nearer to the subsequent short ridge than to the precedent short ridge in the opposite longitudinal directions as viewed from the center of the ridged strap.
Claim 7
Dependent Claim 25 words
The combination of claim 4, wherein each ridge is inclined at an angle varying from 5 to 30 degrees with respect to the perpendicular direction.
Claim 8
Dependent Claim 38 words
The combination of claim 1, wherein two tall ridges are arranged between adjacent short ridges in a staggered relation. Thus providing two sets of alternately arranged short and tall ridges on the one surface of the elongated band.
Claim 9
Dependent Claim 22 words
The combination of claim 7, wherein the ridges are arranged in a direction perpendicular to the longitudinal direction of the ridged strap.
Claim 10
Dependent Claim 22 words
The combination of claim 7, wherein the ridges are inclined to the direction perpendicular to the longitudinal direction of the ridged strap.
Claim 11
Dependent Claim 34 words
The combination of claim 1, wherein additional ridges of less height than the short ridges are integrally connected to the other surface of the elongated band in the opposite relation to the short ridges.
Claim 12
Dependent Claim 16 words
The combination of claim 1, wherein each tall ridge is of an upwardly-diverging shape in section.
