No slip one-piece strap adjustor

A one-piece strap adjustor with at least one strap, comprising:

• a front surface at an exterior of the strap adjustor;
• a back surface at an exterior of the strap adjustor opposite the front surface;
• a side surface at an exterior of the strap adjustor that extends between the front surface and the back surface;
• a first opening in the front surface, wherein the first opening extends completely through the strap adjustor from the front surface to the back surface;
• a second opening in the front surface that extends partially but not completely through the strap adjustor;
• and
• a third opening in the side surface that extends partially but not completely through the strap adjustor and joins with the second opening, wherein a first portion of the side surface adjacent the front surface forms a first edge of the third opening and a second portion of the side surface adjacent the back surface forms a second edge of the third opening, a height of the third opening extends from the first edge of the third opening to the second edge of the third opening;
• wherein at least one strap extends through the strap adjuster along the back surface, through the first opening in the back surface to the front surface, along the front surface to the second opening, through the second opening into the strap adjustor and through the third opening.

A one-piece strap adjustor with a strap, comprising:

• a front surface;
• a back surface opposite the front surface, a first side surface that extends between the front surface and the back surface;
• a second side surface that extends between the front surface and the back surface, the second side surface distal to the first side surface;
• a first void that extends completely through the strap adjustor from the front surface to the back surface;
• and
• a second void that extends partially but not completely through the strap adjustor, the second void being partially enclosed by the back surface and the side surface;
• wherein a strap extends through the strap adjustor along the back surface beginning adjacent to the first side surface, through the first void, along the front surface and through the second void into the strap adjustor from the front surface and out of the second void at the second side surface such that the one-piece strap adjustor does not slip along the strap when at rest, but can be slid along the strap by a user;
• and
• wherein a height H3 of an exit to the second void is greater than a compressed strap thickness Tsc of the strap, but is smaller than an uncompressed thickness Tsu of the strap.
