Abstract

A channel connector for channel members, used in mechanical fastening systems for mechanically securing a flexible sheet relative thereto, each channel member being of generally rectangular form, in transverse cross section, and each channel connector being comprised of a flexible resilient material of a shape generally corresponding to that of the channel members and having bottom, side and top wall portions; transverse spacer means, having opposed sides, on the bottom wall, at about the midpoint of the channel connector axial extent; a channel connector bottom wall having a first aperture of a first predetermined size and shape centered a first predetermined axial distance from one of the spacer means sides and a second aperture of a second predetermined size and shape centered a second predetermined axial distance from the other of the spacer means sides.

The combination of a channel connector for physically connecting and spacing the adjacent end portions of a pair of first and second axially aligned substantially similar channel members, each of said channel member being of generally rectangular form, in transverse cross section, having a substantially flat bottom wall, similarly projecting side walls, and top walls parallel to said bottom wall, said top walls having contoured inner edges separated by a continuous central longitudinal slot, each of said channel members further including an outwardly directed protrusion centered a first distance from the channel member axial outer end surface and having a first dimension, said channel connector being comprised of a flexible resilient material of a generally rectangular form, in transverse cross section, and of a predetermined axial extent having:

(a) bottom and side walls enveloping the corresponding adjacent walls of said channel members, said channel connector also having top walls enveloping at least the transverse outermost portions of the top walls of said channel members;
(b) transverse spacer means, having opposed first and second sides, on said bottom wall, intermediate the ends of said channel connector;
(c) said channel connector bottom wall having a first aperture of a dimension so as to permit the physical retention of the channel member protrusion of the first of said channel members, said first aperture being centered a distance, from the first side of said spacer means, greater than said first distance of said first channel member;
and
(d) said channel connector bottom wall having a second aperture of a dimension greater than the first dimension of the protrusion of the second of said channel members, said second aperture being centered a distance from the second side of said spacer means less than the first distance of said second channel member, said second aperture cooperating with the protrusion of said second channel member so as to physically bias said second channel member axial outer end surface against the second side of said spacer means.
