A cord reel has a housing made from a first sidewall and a second sidewall that are detachable and form a spool-receiving cavity. A spool is disposed within the spool-receiving cavity of the housing. A first port is formed in the first side of the housing and a first length of cord extends from the housing via the first port. A second port is defined by cooperating recesses in the first sidewall and the second sidewall and a second length of cord that is wound around the spool retractably extends out of the second port. One or both of a side weather guard and a cord weather guard are installed to protect the cord reel against weather. The side weather guard is mounted to the first sidewall and covers the first port, and the cord weather guard is mounted between the first and second sidewalls to cover the second port.

A retractable leash device (e.g., for pets, children, or the like) having a length control system for limiting the extendable length of a main line is provided. The device includes a cover plate mounted on a wind-up spool and having at least one ridged channel that interacts with a length control switch during line extension to control the extendable length of the main line while simultaneously maintaining the retractability of the main line.

A Retractable Electrical Trailer Connection System comprising a retractable reel assembly removably mounted to a trailer; an electrical cable, further comprising a first end and a second end; an electrical connector electrically coupled to the electrical cable second end; a guide aperture extending outwardly from the retractable reel assembly, and a stop mechanism removably attached to the electrical cable between the guide aperture and the electrical connector. The electrical cable first end is electrically coupled to the trailer and is wound about a center spool of the retractable reel assembly where the electrical cable second end extends outwardly through the guide aperture. The electrical connector is configured to electrically couple the electrical cable to a standard receptacle located on a rear side of a tow vehicle. The stop mechanism is preferably structured to move along the electrical cable and lock into place.

A hose reel includes a frame, a reel rotatably arranged within the frame and a rewind mechanism with a spring. A removable lid is attached to the frame and encloses an inside of the hose reel from all directions to prevent a user of the hose reel from accessing the inside of the hose reel. An axle is rotatable in relation to the reel. A first end of the spring is attached to the reel and a second end of the spring is attached to the axle. The axle has an outer end connected to the lid to prevent mutual rotation between the lid and the outer end in a direction which decreases the spring force of the spring.

A stop ball for a tube for fluid or energy is provided. The stop ball comprises a singular hollow body. The hollow body comprises and is integral with a first opening for the tube and an attachment means for attaching the stop ball to the tube, the attachment means comprising a second opening for the tube. A method for attaching a stop ball according to any one of the preceding embodiments to a tube for fluid or energy is provided. The method comprising inserting the tube through all three openings; pulling the attachment means at least partly out of the hollow body; and clamping the attachment means onto the tube.

A fiber optic retractable cord reel assembly is disclosed. The fiber optic cord reel assembly includes a continuous fiber optic cord with a retractable end enclosed in a shroud and a stationary end exposed from the shroud. The retractable cord reel may have a rotatable ferrule configured to adapt to an expandable coil having various trajectories within the cord reel.

A tape drive comprises a roll of a tape that can be extended from a rolled state to an extended state. The tape includes a rigid material that supports the tape and a pliable material disposed at least partially on one side of the tape. A compression roller is disposed on a side of the tape and is biased toward the tape. A drive roller is disposed on the other side of the tape. The drive roller comprises an uneven surface that mechanically engages the pliable material of the tape, without protruding through the tape, as a result of the bias of the compression roller forcing the tape toward the drive roller. A motor turns the drive roller to extend the tape from the roll as the protrusions of the uneven surface of the drive roller mechanically engage the pliable material of the tape as the drive roller turns.

A retractable leash device (e.g., for pets, children, or the like) having a length control system for limiting the extendable length of a main line is provided. The device includes a cover plate mounted on a wind-up spool and having at least one ridged channel that interacts with a length control switch during line extension to control the extendable length of the main line while simultaneously maintaining the retractability of the main line.

A Retractable Electrical Trailer Connection System comprising a retractable reel assembly removably mounted to a trailer; an electrical cable, further comprising a first end and a second end; an electrical connector electrically coupled to the electrical cable second end; a guide aperture extending outwardly from the retractable reel assembly, and a stop mechanism removably attached to the electrical cable between the guide aperture and the electrical connector. The electrical cable first end is electrically coupled to the trailer and is wound about a center spool of the retractable reel assembly where the electrical cable second end extends outwardly through the guide aperture. The electrical connector is configured to electrically couple the electrical cable to a standard receptacle located on a rear side of a tow vehicle. The stop mechanism is preferably structured to move along the electrical cable and lock into place.

A pet toy apparatus is provided. The apparatus includes a housing having a bracket for mounting the apparatus onto a structure. A biased reel rotatably disposed in the housing includes an elongated tether wound thereabout. A quick release mechanism disposed on an end of the tether and positioned exterior to the housing is configured to interchangeably receive a pet toy. Rotation of the reel in a first direction winds and retracts the tether into the housing, while rotation of the reel in an opposing second direction unwinds and extends the tether out of the housing. The reel is biased in the first direction so as to tensionably rotate back in the first direction after being rotated in the second direction, thereby automatically retracting the tether. A stopper slidably disposed along the tether is configured to prevent retraction of the tether into the housing.
