1. A retractable oxygen tube assembly comprising:
a housing having a bottom wall and a perimeter wall coupled to and extending from said bottom wall defining an interior space of said housing; an aperture extending through said housing; a reel coupled to said housing, said reel being positioned in said interior space of said housing; a hose having a first end coupled to said reel, said hose being extended around said reel wherein a second end of said hose is selectively extendable from said reel through said aperture in said housing; an oxygen port coupled to said housing, said oxygen port being configured for coupling to an oxygen source wherein oxygen is delivered through said oxygen port, said oxygen port being in fluid communication with said hose wherein said hose is configured for receiving oxygen into said hose and dispensing oxygen through said second end of said hose; a motor coupled to said housing, said motor being selectively engageable to said reel wherein said reel is rotated by said motor retracting said hose onto said reel when said motor is actuated; a tension mechanism coupled to said housing, said motor being coupled to said tension mechanism, said tension mechanism adjustably urging said motor into abutment with said reel wherein frictional engagement between said motor and said reel is adjusted by said tension mechanism; and said tension mechanism comprising: a post, said motor being slidably coupled to said post proximate a first end of said post; a wing nut selectively positionable along a length of said post; and a biasing member coupled to said post extending between said wing nut and said motor such that adjustment of said wing nut along said post varies resistance to sliding of said motor relative to said post. |
