Rapid attachment buckle

1. For use with a flexible strap having a substantially uniform width and thickness and an end tab of increased thickness, a buckle for capturing and releasably retaining said end tab, said buckle comprising:

a base;

parallel side walls extending upwardly from and cooperating with said base to define an open-ended receiving channel having an entry end and an exit end;

first slots extending transversally across said base, said buckle being aftached to said strap by weaving said strap into and out of said channel through said first slots; and

flanges spaced vertically from said base and extending inwardly in cantilever fashion from said side walls to define an open-ended second slot communicating with and extending along the length of said receiving channel, said second slot being configured and dimensioned to accommodate longitudinal pinching and lateral insertion of said strap into said receiving channel, said flanges including:

undersides configured to accommodate receipt of said end tab in said receiving channel via said ently end, and to releasably wedge said end tab in and prevent withdrawal of said end tab from said receiving channel via said exit end;

converging sections leading from a maximum width of said slot at the entry end of said receiving channel to a reduced width of said slot at an intermediate location along the length of said channel;

jamming surfaces that slope inwardly into the receiving channel and extend from the entry end of the receiving channel toward stop surfaces to accommodate the lateral insertion and longitudinal pinching; and

non-sloping surfaces that extend from said stop surfaces toward the exit end of the receiving channel to releasably wedge said end tab within the receiving channel.

2. The buckle of claim 1 wherein said base is formed as an integral part of a carrier structure.

3. For use with a flexible strap having a substantially uniform width and thickness and an end tab of increased thickness, a buckle for capturing and releasably retaining said end tab, said buclde comprising:

a base;

parallel side walls extending upwardly from and cooperating with said base to define an open-ended receiving channel having an entry end and an exit end; and

flanges spaced vertically from said base and extending inwardly in cantilever fashion from said side walls to define an open-ended slot communicating with and extending along the length of said receiving channel, said slot being configured and dimensioned to accommodate longitudinal pinching and lateral insertion of said strap into said receiving channel, said flanges including;

undersides with downwardly sloping jamming surfaces configured to frictionally retain said end tab in said receiving channel;

converging sections leading from a maximum width of said slot at the entry end of said receiving channel to a reduced width of said slot at an intermediate location along the length of said channel;

jamming surfaces that slope inwardly into the receiving channel and extend from the entry end of the receiving channel toward stop surfaces to accommodate the lateral insertion and longitudinal pinching; and

non-sloping surfaces that extend from said stop surfaces toward the exit end of the receiving channel to releasably wedge said end tab within the receiving channel.

4. The buckle of claims 1 or 3 wherein said end tab defines a shoulder extending transversally across the width of said strap, and wherein the stop surfaces are engageable with said shoulder.

5. The buckle of claim 3 wherein said base is secured to a section of said strap.

6. The buckle of claim 5 further comprising attachment slots extending transversally across said base, said buckle being attached to said strap by weaving said strap into and out of said channel through said attachment slots.

7. The buckle of claim 3 wherein said base is formed as an integral part of a carrier structure.
