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.

Embodiments of the invention are directed to adjustable closure devices. One embodiment has a strap, a connector attached to a strap end, a chafe mounted on the strap behind the connector, and a hinged handle on the chafe. The chafe has two outer bars and a central bar, these bars defining strap through-paths. The strap end-region has path segments arranged, directionally from the strap's central region toward the strap end at the chafe, or, in embodiments that configure the strap as a pulley, at the connector. An adjustable length region of the strap spans between the chafe and the connector. An elevatable handle configuration allows a user to pull the chafe to which it is connected along the strap, away from connector.

A cord reel assembly is provided that includes a plenum-rated enclosure with a cord reel secured in the enclosure where the enclosure forms an air tight seal from a plenum space, but is open to a finished space. Thus, a cord reel assembly is provided that includes a cord reel and a plenum rated enclosure. The cord reel has a base plate. The enclosure is open at a bottom edge. The base plate is secured in the enclosure.

A retractable reel system includes a reel, a gear assembly, a paddle wheel and a spring. The reel includes a concentric wheel shaft where the reel and wheel shaft rotate to wind and unwind a length of material from the reel. The gear assembly engages with an end of the wheel shaft to provide a gear reduction ratio between the wheel shaft and an output shaft of the gear assembly. The paddle wheel is connected to and concentric with the output shaft, and the paddle wheel includes a paddle that extends beyond an outer edge of the paddle wheel that rotates with the paddle wheel. The spring is arranged outside the outer edge of the paddle wheel. The spring is compressed by the paddle to store an energy when the reel is rotated to unwind the length of material from the reel. The stored energy is used to rotate the reel to wind the length of material around the reel.

A display device including a display; and a controller configured to receive an input of a voice command, and output a result of the voice command differently according to a mode of the display even for the same voice command.

The present disclosure relates to a multifunctional retractable puller for pet, which includes a housing, a reel, a ribbon wound on the reel and a zinc alloy hook buckle, a handle integrated with the housing, a handle metal buckle, and a garbage bag device mounted on the metal buckle. The reel-locking key and the reel-opening key of the present disclosure form a switching group. The LED lamp has a function of warning and entertainment, which is convenient for users to warn others when crossing the road at night. The puller has the functions of charging the battery and being charged by the battery, so users do not need to replace the battery. The puller is equipped with a garbage bag device, from which the garbage bag can be taken out at any time, thus facilitating the users dispose of pet excrement at any time.

Embodiments of the invention are directed to adjustable closure devices. One embodiment has a strap, a connector attached to a strap end, a chafe mounted on the strap behind the connector, and a hinged handle on the chafe. The chafe has a two outer bars and a central bar, these bars defining strap through-paths. The strap end-region has path segments arranged, directionally from the strap's central region toward the strap end at the chafe, or, in embodiments that configure the strap as a pulley, at the connector. An adjustable length region of the strap spans between the chafe and the connector. An elevatable handle configuration allows a user to pull the chafe to which it is connected along the strap, away from connector. As the chafe moves along the strap, the strap can transition between a large circumference configuration and small circumference. Some embodiments have a strap friction-locking mechanism associated with the handle and the chafe.

A retractable leash with improved locking and unlocking mechanism, having a housing; a spool disposed inside the housing and biased towards the winding direction; a braking means; a locking means rotatable between a locking position to stop rotation of the spool towards the unwinding direction and an unlocking position; a biasing means which biases the locking means towards the unlocking position; a press button pivotable between a pressed position and a released position; an actuating means rotatably engaged with the press button and the locking means between a default position and an actuating position; and a sliding button having an upper portion exposing on the upper portion of the press button and a lower portion extending downwards through the press button into the housing.

A dual-web retractor includes a frame having first, second and third sidewalls spaced apart from one another with the second sidewall positioned between the first and third sidewalls, a spool rotatably mounted to and between the first, second and third sidewalls, the spool having a first spool section defined between the first and second sidewalls and a second spool section defined between the second and third sidewalls, a first web having one end coupled to the first spool section, and a second web having one end coupled to the second spool section, wherein rotation of the spool causes the first and second webs to be simultaneously paid taken up on or paid out from the first and second respective spool sections.

A tether includes a housing defining a cord aperture, a spool located within the housing and configured to rotate about a spool axis in either an extending direction or a rewinding direction, a cord wound around the spool and configured to pass through the cord aperture, a biasing member coupled to the spool, and a retractor lock. The biasing member biases the spool to rotate in the rewinding direction to retract the cord into the housing. The retractor lock is movable between a locked position and an unlocked position. The retractor lock prevents rotation of the spool when in the locked position and allows rotation of the spool in the unlocked position. The retractor lock is moves from the locked position to the unlocked position in response to a threshold cord force on the cord.
