The present invention is a retractable pet leash with a variable brake system to control a pet. The variable braking system can be engaged or disengaged by the user via 3 methods. The first method is via a handle that is directly connected to the brake. The second method, also actuated by the user is a one touch brake system that uses the rotation of the reel to slowly apply the variable brake over several rotations of the reel. The third method allows the user to set the length of the leash cord and when the set length of the cord is met, engages the one touch brake system. The retractable pet leash provides a system to set the length of the leash cord being let out and ensures that the leash cord is kept taught between the user and the pet and notifies the user when the set length has been reached and applies variable braking in a steady and predictable manner to smoothly stop the pet.

The present disclosure involves a belt drive mechanism which can be used to pay out or draw belt to or from a belt actuated system (or belt driven system). The mechanism features a self-winding spool which can automatically wind or unwind portions of the belt as they are withdrawn from, or fed to the belt actuated system. A second rotational axle (idler shaft), with one or more sheaves (e.g., pulley's or rollers) can be rotationally coupled to a capstan via a belt, and can be utilized to drive additional mechanisms in the belt drive mechanism, such as a winding mechanism.

A retractable leash assembly for a pet animal, such as a dog, is provided. The leash assembly includes a casing body with a handle attached to the body by an at least one hinge joint, a braking device, and a spool arrangement with an extendable lead line wound thereabout and configured attachable to the pet animals' collar or harness, wherein in the leash assembly the handle is configured to articulate about the joint with regard to the casing body, the articulation movement of the handle being triggered by the pulling force exerted on the lead line by the animal kept on the leash, and wherein, by virtue of the articulation movement the braking device actuates a braking action causing the lead line to reduce unwinding speed proportionally with an increase in the pulling force.

A rolling-unrolling device for a protective cover for covering a surface to be protected is presented. The device is self-propelling and includes a braking system for blocking the rotation of at least one drive wheel of the carriages and causing the cover to be automatically tensioned during the rolling up thereof on the roller tube. This braking system includes a movable pawl integral with each of the carriages, and a ratchet wheel integral with the drive wheel of each of the carriages, such that, in the direction of rotation corresponding to the unrolling of the cover, the pawl is not engaged with the ratchet wheel and the braking system is in the passive position, and in the opposite direction of rotation corresponding to the rolling up of the cover, the pawl is engaged with the ratchet wheel and the braking system is in the active position.

Provided is a reel for a conductor of an electric fence. The reel includes a bobbin, a frame for supporting the bobbin, and a connector. The connector can be two jaws and can have passages to connect the reel to a support such as a conductor of an existing fence or a tube of a vehicle. One of the jaws can be wide for stability. The connector can have an electrical conductor for connecting to the support and electrifying the conductor. The connector can also be operated by a trigger and can have a locking mechanism. The frame can be a one-piece frame made of plastics material. The reel can have a spreader and a hot-up bar. The reel can have a crank that can be disengaged from the bobbin and a brake that is applied when the crank is disengaged.

A system includes a frame and a first pair of rollers coupled to a first side of the frame. The first pair of rollers is configured to support a first end of a pipe reel. The system also includes a first cradle disposed longitudinally between the first pair of rollers and a second pair of rollers coupled to a second side of the frame. The second pair of rollers is configured to support a second end of a pipe reel. The system also includes a second cradle disposed longitudinally between the second pair of rollers, a pipe guide coupled to a third side of the frame between the first and second sides, a pipe brake coupled to the frame, and a pipe re-spooler coupled to the frame.

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 one-way clutch unit for a fishing reel is disclosed. The one-way clutch is configured to brake a rotation of a shaft member of the fishing reel. The one-way clutch includes a rolling element and an outer member. The rolling element contacts the shaft member in a radial direction away from an axle of the shaft member. The outer member is disposed outside the rolling element in the radial direction. The outer member is configured to rotate in only one direction along a circumferential direction around the axle. The outer member includes a first external force receiving portion that receives a first external force in an axial direction of the shaft member.

A pet tractor with a storage bin and a storage bin opening control method. The pet tractor comprises a shell, a rotating wheel, a storage bin, a braking assembly and a locking assembly, wherein the rotating wheel is arranged on the shell, and a traction rope is arranged on the rotating wheel; the storage bin is arranged at one side of the shell; the braking assembly is arranged on the shell, is arranged above the rotating wheel and is used for limiting the rotation of the rotating wheel; the locking assembly is arranged on the shell, located at one side of the braking assembly and used for controlling the braking assembly to be in a braking state and controlling the storage bin to be opened and closed.

A belt drive mechanism which can be used to pay out or draw belt to or from a belt actuated system (or belt driven system). The mechanism features a self-winding spool which can automatically wind or unwind portions of the belt as they are withdrawn from, or fed to the belt actuated system. A second rotational axle (idler shaft), with one or more sheaves (e.g., pulley's or rollers) can be rotationally coupled to a capstan via a belt, and can be utilized to drive additional mechanisms in the belt drive mechanism, such as a winding mechanism.
