Abstract
Disclosed is a support frame for a breathing apparatus comprising a cylinder cradle for supporting a compressed gas cylinder, a cylinder-retaining strap having a first end secured to the support frame at a first fixing point and a second end adjustably secured to the cylinder-retaining strap between the first and second ends, wherein the adjustable strap loop is secured to a second fixing point so as to form an effective strap length between the first and second fixing points, and a releasable third fixing point, wherein the effective strap length is adjustable by adjusting a position of the second end along the strap to thereby adjust a size of the adjustable strap loop, and releasably securing the adjustable strap loop to the third fixing point.
Claims11
A support frame for a breathing apparatus comprising:
- a cylinder cradle for supporting a compressed gas cylinder on the support frame;
- a cylinder-retaining strap having a first end secured to the support frame at a first fixing point and a second end adjustably secured to the cylinder-retaining strap between the first and second ends so as to form an adjustable strap loop formed of a portion of the cylinder-retaining strap, wherein the adjustable strap loop is secured to a second fixing point so as to form an effective strap length between the first and second fixing points;
- and
- a releasable third fixing point;
- wherein the effective strap length is adjustable by:
- adjusting a position of the second end along the strap to thereby adjust a size of the adjustable strap loop;
- and
- releasably securing the adjustable strap loop to the third fixing point.
A method of adjusting a cylinder configuration of a breathing apparatus comprising:
- providing a support frame comprising a cylinder cradle for supporting a compressed gas cylinder on the support frame and a cylinder-retaining strap having a first end and a second end;
- securing the first end to the support frame at a first fixing point and adjustably securing the second end to the cylinder-retaining strap between the first and second ends so as to form an adjustable strap loop formed of a portion of the cylinder-retaining strap, and
- securing the adjustable strap loop to a second fixing point so as to form an effective strap length between the first and second fixing points;
- and
- adjusting the effective strap length by:
- adjusting a position of the second end along the cylinder-retaining strap to thereby adjust a size of the adjustable strap loop;
- and
- releasably securing the adjustable strap loop to a releasable third fixing point.
