a surveillance apparatus comprising:—a retractable support member the member having a first end and a second end; a housing; a spooling mechanism mounted at the housing, and being rotatable relative to the housing, and being attached to the second end of the retractable support member, the spooling mechanism being: operable to rotate in a first direction to convert the retractable support member from a coiled condition to an extended condition and thereby pay-out the support member from the housing, operable to rotate in a second direction opposite to the first to convert the retractable support member from the extended condition to the coiled condition and thereby retract the support member into the housing; a mount attached to the first end of the retractable support member; a surveillance device attached to the mount for receiving environmental signals, a human interface remote from the surveillance device; and a signal interface for relaying the signals received at the surveillance device to the human interface, such that the surveillance device may be supported, remote from the human interface by paying out the member, and wherein the signal interface comprises a transmitter at the surveillance device for sending an first electromagnetic signal; and the human interface comprises a receiver for receiving the first electromagnetic signal.

A protective case for a portable electronic device includes a shell, an aperture, an internal electrical connector, a rechargeable battery, docking receptacles, and an external electrical connector. The shell receives at least a portion of the portable electronic device while the aperture provides access to a user interface of the installed portable electronic device. The internal electrical connector electrically interfaces with the installed portable electronic device. The docking receptacles provide docking locations for removably stowing wireless earbuds when the earbuds are not in use. Each docking receptacle includes an electrical interface for electrically interfacing the rechargeable battery of the protective case to the wireless earbuds for recharging. The external electrical connector receives electrical power from an external power source for recharging the rechargeable battery of the protective case.

An adjustment device includes a housing supporting a rotatable spool that is operably coupled to a tension line. The spool is configured to rotate about a first axis in a first direction to wind the tension line around the spool and is configured to rotate about the first axis in a second direction opposite the first rotational direction to unwind the at least one tension line from the spool. The device includes a lever pivotally coupled to the housing and configured to rotate about a second axis. The lever is selectively coupled to the spool to drive rotation of the spool in the first direction. The device also includes a release mechanism that is configured to selectively release the spool such that the spool is free to rotate in either the first or second direction in response to manual forces applied to the release mechanism.

A two or more subject retractable leash, and methods of use thereof, is disclosed, which includes a roll-back feature on each retractable leash. The leashes may be locked in place by engaging a single lever. The leashes retract regardless of whether the spools are locked or unlocked. Each leash retracts independently of the other leashes, such that a dual leash may be used to walk one subject. In some embodiments, a single subject retractable leash includes a roll-back feature that provides and allows for leash retraction, whether or not a brake associated with a spool thereof is engaged.

A reel assembly (10) having a spool (20) comprising a drum core (22) and side disc flanges (24) attached to the drum core (22) for retaining a wound hose (26) on the spool (20), and a release mechanism (120) operatively engaging the spool (20) via a drive shaft (110). The release mechanism (120) has a pair of rotatable hubs (132, 134) arranged in axial alignment and having a clamping spring (136) fitted around the rotatable hubs (132, 134) and arranged to clamp the hubs (132, 134) together in fixed rotational relation, wherein the clamping spring (136) opens to releases the rotatable hubs (132, 134) when the spool (20) is rotated in a payout direction so that the rotatable hubs (132, 134) disengage and the spool (20) can freewheel.

Embodiments of the present invention provide an apparatus for convenient tightening and loosening of strings such as those found in shoelaces of footwear. The apparatus includes a rotating portion within a base portion. A cover portion, when operated in a first position, provides a ratchet movement that allows rotation in a tightening direction while preventing movement in a loosening direction. When the cover is moved to a second position, the ratchet mechanism disengages, and the strings can then be easily loosened.

A two or more subject retractable leash, and methods of use thereof, is disclosed, which includes a roll-back feature on each retractable leash. The leashes may be locked in place by engaging a single lever. The leashes retract regardless of whether the spools are locked or unlocked. Each leash retracts independently of the other leashes, such that a dual leash may be used to walk one subject. In some embodiments, a single subject retractable leash includes a roll-back feature that provides and allows for leash retraction, whether or not a brake associated with a spool thereof is engaged.

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.

Clothing drying device has: a drum with a rope wound around; a casing body having an entrance/exit surface and storing the drum, the entrance/exit surface being provided adjacent to a wall surface to which the casing body is fixed, the entrance/exit surface allowing the rope to go in and out; and a gate-shaped guide member provided on the entrance/exit surface, comprising a hole portion provided inside the guide member and the rope is passed through, a pair of pole portions extending in the direction intersecting with the wall surface and having an arc surface becoming convex toward the hole portion, and a beam portion passed between the pair of pole portions at the end portion opposite to the end portion of the wall surface side of the pair of pole portions and having an arc surface becoming convex toward the hole portion.
