The disclosure describes a cart having a frame, a front assembly attached to the frame, a back assembly attached to the frame, and a rotating enclosure assembly attached to the frame. The rotating enclosure assembly includes a removable side and a cage. The removable side is removable from the cage to aid in loading or unloading coils of flexible tubing and can be fixedly attached when installing the flexible tubing coiled around the rotating enclosure assembly. The cart may further include an adjustment mechanism that allows the cart to be adjusted between a mobile state and an immobile state. The back assembly may include one or more immobilizers configured to immobilize the cart into the immobile state.

A retractable leash system includes a housing, a leash, a spool, and a brake. The spool is attached to the leash and disposed within the housing. The leash is configured to be rotationally biased so as to urge the leash into a spooled configuration. The brake includes an operating button, a compression spring, and a brake member coupled to the operating button. The brake member is associated with the compression spring and is configured to engage the spool by operation of the operating button, such that, when the brake is engaged, the spool is prevented from rotating in an unspooling direction and capable of rotating in a spooling direction.

A magnetic retractable line divider may include at least a reel assembly having a shell, and a magnetic portion is installed thereon. An elastic line divider belt is wound on the reel assembly, and a magnetic member is connected to a lateral end of the line divider belt. The line divider belt is configured to be horizontally pulled out from the reel assembly and travel a preferred distance to attach to a magnetic object, thus achieving line divider effect. Moreover, when someone pushes against the line divider belt with or over a preferred force, the magnetic member is configured to be detached from the magnetic object and automatically retracted into the reel assembly, thus avoiding accident.

A twistless cable deployment apparatus is provided for deploying cable. The apparatus includes a level winder that can be joined to a winch. The level winder is in a fixed position relative to the cable winch. The level winder has a non-rotating fixed spool that stores the cable by wrapping the cable around the spool. A rotating base is disposed coaxially with the fixed spool and rotates around the axis of the fixed spool. A post is mounted on the rotating base, and a traveler is slidably mounted on the post. A traveling guide eye is joined to the traveler. By rotation of the rotating base, cable is deployed from the fixed spool. A primary guide eye can guide the cable to the winch.

A novel lacing device and an anti-reverse mechanism thereof are provided. The lacing device uses a novel swing arm-stop piece-gap mechanism as the anti-reverse mechanism, and the anti-reverse mechanism has double self-locking functions and a reverse deviation limiting function. Three effects are integrated, such that the lacing device using the novel anti-reverse mechanism not only has excellent hand feeling when the lace is tensioned, but also can effectively avoid the accidental loosening of the lace, and has excellent use reliability and durability.

A three-point safety belt includes a belt body, a winder, a shoulder belt guide ring, and a lock tongue. The winder and the shoulder belt guide ring are fixed onto a vehicle body. The winder is located below the shoulder belt guide ring. The lock tongue is disposed on the belt body. The lock tongue divides the belt body into a shoulder belt and a waist belt. The shoulder belt penetrates through the shoulder belt guide ring. The free end, away from the lock tongue, of the shoulder belt and the free end, away from the lock tongue, of the waist belt are both wound in the winder. The winder synchronously winds or unwinds the shoulder belt and the waist belt.

A retractable leash device has a first handle for holding the device, a spool and a leash wound on the spool. There is a spring-based rewind mechanism for the leash. A second handle is provided for manually retracting the leash. A mechanical coupling between the second handle and the spool provides a second rewind mechanism for the leash. This second rewind mechanism is used to pull an animal back toward the owner in a safe and convenient way.

A device for the coiling, storage and payout of cable, hose, cord and wire having a bucket creating a storage space defined by a round bucket bottom, a peripheral wall cylindrically extending from the round bucket bottom and terminating in a round open top and a bucket longitudinal axis passing through its geometric center. A spool having a cylindrical core, spaced apart top and bottom flanges and a spool longitudinal axis passing through its geometric center. A nub extends between and spaces the bottom flange from the bucket bottom, the bucket further having an opening in its peripheral wall, the opening having elongated sides extending longitudinally and parallel to the bucket longitudinal axis and extending the distance between the top and bottom flanges and relatively low friction contour rails positioned along the elongated sides and an extendible handle secured to the top flange.

A bag for transporting tools and building supplies includes a body, a first spool, a second spool, an electrical plug coupled to a first electrical cord, and an electrical connector coupled to a second electrical cord and defining an electrical outlet. The body includes a side panel coupled to and extending from a base member. The base member and the side panel cooperate to define an internal volume. The first spool and the second spool are each rotatable relative to the body and positioned within the internal volume. The first and second electrical cords wrap around the first and second spools, respectively, and extend outside of the body. The electrical plug is electrically coupled to the electrical connector. The electrical plug is interfaces with an external power source such that the electrical outlet receives electrical power from the external power source.

Example dynamically adjustable tether systems are described herein. An example tether system for use with an unmanned aerial vehicle (UAV) may include a base and a vertically-oriented elongate structure having an adjustable height. For instance, the elongate structure may include a lower end, and an upper end. The elongate structure may also couple to the base proximate the lower end. The system may further include a tether that extends from a first coupling-point positioned proximate the upper end of the elongate structure to a second coupling-point positioned on the UAV and a computing system configured for performing a set of acts, such as detecting a change in height of the elongate structure, and causing the tether to be reconfigured within the tether system based on the detected change in height of the elongate structure.
