• a bumper being coupled to the platform, the bumper being positioned on the front edge and each lateral edge of the pair of lateral edges of the platform, the bumper including a resiliently compressible material wherein the bumper is configured to inhibit the platform from damaging objects;
• a reel casing being coupled to the handle, the reel casing having a front wall, a back wall, and a peripheral wall being coupled to and extending between the front wall and the back wall to define an interior space, the front wall being circular, the back wall being circular, the reel casing being spaced from the platform wherein the reel casing is suspended from the handle above the platform, the reel casing being pivotably coupled to the handle wherein the reel casing is pivotable 180° around the handle;
• an aperture extending through the peripheral wall of the reel casing;
• a reel being rotatably coupled to the reel casing, the reel being positioned within the interior space of the reel casing, the reel extending between the front wall and the back wall, the reel being centrally positioned relative to each of the front wall and the back wall;
• a tube being coiled around the reel, the tube having a first end being coupled to the reel, the tube having a second end being distal to the first end, the second end being configured to be fluidly coupled to an oxygen source, the tube being outwardly extendable from the reel casing through the aperture, the reel being rotatable in a first direction to uncoil the tube for extension of the tube from the reel casing, the reel being rotatable in a second direction to coil the tube around the reel for retraction of the tube into the reel casing, the tube having a length between 12.2 meters and 18.3 meters wherein the tube is configured to transfer oxygen from the oxygen source to the reel casing whereby the tube is configured to facilitate the user in receiving oxygen from the oxygen source;
• an adaptor port being coupled to the reel casing, the adaptor port extending through the front wall, the adaptor port being aligned with the reel wherein the adaptor port is fluidly coupled to the first end of the tube, the adaptor port being configured to be coupled to an oxygen hose to fluidly couple the oxygen hose to the tube;
• a reel spring being coupled to the reel, the reel spring being coupled to the first end of the tube, the reel spring winding around the reel when the reel rotates in the first direction to uncoil the tube for extension of the tube from the reel casing, the reel spring unwinding from the reel when the reel rotates in the second direction to coil the tube around the reel for retraction of the tube into the reel casing, the reel spring having a spring tension, the spring tension increasing as the reel spring winds around the reel, the spring tension being released when the reel spring unwinds from the reel wherein the reel spring is configured to retract the tube into the reel casing;
• a tube lock being coupled to the reel casing, the tube lock being releasably engageable with the tube wherein the tube lock selectively inhibits the tube from being extended or retracted relative to the reel casing, the tube lock including:
• a pair of rollers being rotatably coupled to the peripheral wall of the reel casing, the pair of rollers being positioned on opposing edges of the aperture wherein the tube slides between the pair of rollers as the tube extends and retracts relative to the reel casing, the pair of rollers gripping the tube when the tube is pulled outward from the reel casing wherein the pair of rollers inhibit the tube from being retracted into the reel casing, the pair of rollers releasing the tube when the tube is pulled upward relative to the reel casing to retract the tube into the reel casing;
• a ratchet being positioned in the interior space of the reel casing adjacent to the peripheral wall, the ratchet being coupled to the reel wherein the ratchet rotates in the first direction when the reel rotates in the first direction and wherein the ratchet rotates in the second direction when the reel rotates in the second direction;
• a locking pawl being pivotably coupled to the reel, the locking pawl including:
• a main body;
• and
• a finger being coupled to and extending downwardly from the main body, the finger contacting the ratchet when the locking pawl is pivoted downwardly to inhibit the ratchet from being rotated in the second direction and the tube from being retracted into the reel casing, the finger being spaced from the ratchet when the locking pawl is pivoted upwardly;
• and
• a ratchet spring being coupled to the reel, the ratchet spring being coupled to the locking pawl wherein the ratchet spring pivots the locking pawl upwards from the ratchet when the tube is pulled upward relative to the reel casing, the ratchet spring being biased to pivot the locking pawl downwardly toward the ratchet when the tube is pulled outwardly from the reel casing;
• and
• a retainer being coupled to the reel casing, the retainer being coupled to the handle wherein the retainer pivotably secures the reel casing to the handle, the retainer including:
• a bracket being coupled to the handle, the bracket having a bracket wall and a pair of bracket lips being coupled to and extending forwardly from the bracket wall;
