A manual reel retractable leash apparatus for manually retracting a leash to control a dog includes a retractable leash spool coupled within a leash body. A leash is windingly coupled around the leash spool and extends through a leash aperture of the leash body. A crank housing is coupled to the leash body and a drive mechanism is coupled within crank housing. The drive mechanism is in operational communication with the leash spool and an outer face of the crank housing. A crank handle is coupled to the outer face to provide a place for a user to rotate the crank housing to power the drive mechanism and retract the leash.

A portable retractable oxygen tubing reel providing improved portability and mechanical reeling functionality. The portable retractable oxygen tubing reel includes tubing wrapped around an inner circular component stored within an outer storage compartment whereby a handle attached to the inner circular component may be rotated to wind or unwind tubing from the portable retractable oxygen tubing reel. Tubing may then be connected to a medical oxygen storage device at one end and a nasal oxygen cannula positioned near in proximity to a patient's nose for breathing oxygen at the other end.

A curtain winding device includes a beam, a power mechanism mounted to the beam, a transmission rod driven by the power mechanism to rotate, and two reels fitted about the transmission rod and relatively fixed with the transmission rod in a circumferential direction. Each reel is wound with a drawstring. A drawstring holder is disposed on the beam to guide the drawstring to be wound on the reel. The beam is fixed with a nut. Each reel includes a screw segment screwed to the nut, and a cone segment gradually increasing in an outer diameter along an extending direction. An end of the reel away from the screw segment is provided with a fixing portion for fixing a distal end of the drawstring, and a positioning portion protruding from an outer side surface of the reel to abut against the drawstring holder to position an initial position of the reel.

Implementations of spool devices may include a frame including an anchor, the anchor configured to directly couple to a belt of a user, an axle coupled through the frame, and a first spool coupled over a first portion of the axle. The first portion of the axle may extend entirely through the first spool. The spool device may also include a second spool coupled over a second portion of the axle. The second portion of the axle may extend entirely through the second spool. The spool device may also include a first spool handle directly coupled to an outer wall of the first spool, a second spool handle directly coupled to an outer wall of the second spool, a first hose roller directly coupled to the frame, and a second hose roller directly coupled to the frame.

A reel based closure device includes a housing, a tension member, a spool that is rotatably positioned within the housing, and a tightening component that is positioned axially above the spool and that is operably coupled therewith so that an operation of the tightening component causes the spool to rotate within the housing to wind the tension member about the spool. The reel based closure device also includes a coupling component that is separate from the tension member and that frictionally engages with a distal end of the tension member so that the coupling component is removably fixed to the tension member. The spool component includes a coupling feature within which the coupling component is positioned to attach the tension member to the spool.

A ratcheting strap storage assembly for includes a box that has a first compartment and a second compartment. The first compartment contains a ratcheting mechanism of a ratcheting strap for storage. The second compartment contains a strap of the ratcheting strap being coiled therein for storage. A winding mechanism is rotatably coupled to the box and the strap of the ratcheting strap is coupled to the winding mechanism. The winding mechanism wraps the strap therearound when the winding mechanism is rotated in a winding direction to coil the strap within the second compartment for storage. The winding mechanism unwinds the strap when the winding mechanism is rotated in the unwinding direction to release the strap from the box.
