1. A fastening system comprising a closure member, a stretch member, and a landing member:
(a) wherein the landing member has a downward-pointing, chevron shape, the medial portion of the landing member dipping below a horizontal line drawn between the upper ends of the outer edges of the landing member; (b) wherein the closure member is divided into Tab Zones characterized as follows:
i. Tab Zone A is defined as the portion of the closure member that is not attached to nor lying in the same vertical plane, when the member is laid flat in horizontal position, as viewed from above, as the stretch member, less the portion of Tab Zone B;ii. Tab Zone C is defined as the portion of the closure member that is attached to and lies in the same vertical plane, when the member is laid flat in horizontal position, as viewed from above, as the stretch member, less the portion of Tab Zone B;iii. Tab Zone B occupies the transitional area between Tab Zone A and Tab Zone C, and is defined as a portion of the closure member which includes both a sub-portion that is not attached to nor lying in the same vertical plane, when the member is laid flat in horizontal position, as viewed from above, as the stretch member and a sub-portion that is attached to and lies in the same vertical plane as the stretch member; andiv. wherein the Tab Zones are parallel to each other and their lateral borders are straight lines; (c) wherein the stretch member is divided into Ear Zones characterized as follows:
i. Ear Zone A is defined as the portion of the stretch member that lies above the horizontal line drawn at the upper point of intersection between the stretch member and the closure member;ii. Ear Zone B is defined as the portion of the stretch member that lies between the horizontal line drawn at the upper point of intersection between the stretch member and a closure member and the horizontal line drawn at the lower point of intersection between the stretch member and the closure member;iii. Ear Zone C is defined as the portion of the stretch member that lies below the horizontal line drawn at the lower point of intersection between the stretch member and the closure member; andiv. wherein the Ear Zones are parallel to each other and the common borders of Ear Zones A and B, and the common borders of Ear Zones B and C, respectively, are straight lines; (d) wherein the angle at which the closure member travels through each of the Tab Zones is characterized by the closure member's position when attached to the stretch member, as follows:
i. Tab Angle A is defined as the angle between: (i) a line drawn from the point at which one edge of the closure member intersects the common border of Tab Zones A and B, and the point at which the same edge of the closure member intersects the other border of Tab Zone A; and (ii) a line drawn upon such other border of Tab Zone A;ii. Tab Angle B is defined as the angle between: (i) a line drawn from the point at which one edge of the closure member intersects the common border of Tab Zones A and B, and the point at which the same edge of the closure member intersects the common border of Tab Zones B and C; and (ii) a line drawn upon the common border of Tab Zones A and B;iii. Tab Angle C is defined as the angle between: (i) a line drawn from the point at which one edge of the closure member intersects the common border of Tab Zones B and C, and the point at which the same edge of the closure member intersects the other border of Tab Zone C; and (ii) a line drawn upon the common border of Tab Zones B and C; andwherein Angle A is not equal to or substantially similar to Angle B, and/or, Angle B is not equal to or substantially similar to Angle C; andwherein: (a) Angle B is greater than Angle A, and Angle A is greater than Angle C; (b) each of Angles A, B, and C, independently, is from about 45 to about 75°; or (c) both (a) and (b). |
