The invention relates to extensible leashes for domestic animals comprising a means for blocking extension of a cord (6) and allows the cord (6) to be extended up to a given maximum length in a regulated fashion. The automatically regulated leash for domestic animals that consists of a rind-shaped hollow body (12, 2) with a handle, wherein a winding roll with a cord (6) is mounted, the free end of the cord (6) is outwardly withdrawn through an opening in the body (12, 2), a stop (8) mechanism for the cord (6) that is regulated by a button (7) located on the body (12, 2). According to the invention, length of the cord (6) is from 2.5 to 3.5 meters. The cord (6) is configured to be wound on the roll that is mounted on guides in the body (12, 2) and comprises, on an inner cylindrical surface, teeth that are internally engaged with a toothed drum (4) mounted on the shaft fixedly attached in a cavity of the handle that is made as an elongated protrusion that has an elliptical shape in cross-section and made integrally with the body (12, 2). Inside the toothed drum (4) there is mounted a spiral band spring (5) that is made of a high-carbon alloyed steel having a Mn content of not more than 1.2%, which has a free end that is fixed on the shaft, and another one that is fixed on a lateral inner wall of the drum (4) having an operational stroke range along the diameter of from 4 to 15 mm. Width of the band spring (5) is within 12±5 mm, length in a deployed state is 2500±800 mm, thickness is 0.1±0.03 mm. Therewith, the diameter of the toothed drum (4) is 0.25-0.40 of the diameter of the toothed surface of the winding roll. The cord (6) is a band that has light-reflecting elements. The body (12, 2) and the internal components of the structure are made of ABS-plastic. The body (12, 2) portion that is provided with the opening for withdrawal of the free end of the cord (6) is displaced relative to the central axis thereof, while the center of gravity is located closer to the handle. The hollow ring-shaped body (12, 2) is made from two symmetrical half pieces. The band spring (5) has a high fatigue strength limit.

A system, comprising a harness configured to be releasably attached to a portion of an animal; a retractable leash assembly comprising a first structural feature and a second structural feature; a receptacle coupled with the harness, the receptacle comprising a first structural feature a second structural feature; wherein the first structural feature of the retractable leash assembly is configured to be releasably mated with the first structural feature of the receptacle upon application of a force on the retractable leash assembly causing at least a portion of the retractable leash to move in a first direction; and wherein the second structural feature of the retractable leash assembly is configured to be releasably mated with the second structural feature of the receptacle upon application of a force on the retractable leash assembly causing at least a portion of the retractable leash to move in a second direction.

A multifunctional personal health monitor with an activity tracker embedded into a pet leash is provided. The energy of a pet pulling the leash cord is converted to an electrical power to run and to analyze operation of multiple biometric sensors embedded into the leash. The physical activities of the pet and its owner may be tracked. The obtain biometric information may be wirelessly transmitted for additional processing or an emergency call can be initiated. The generated by pet movement electrical power may be used to charge various external devices.

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.

An illuminated retractable strap assembly includes a rotatable strap spool, a strap structure having a first end fixed to the strap spool and a second end having a connector. The assembly includes a retraction mechanism for retracting the strap structure, the strap structure includes one or more elongated optical fibers for transmitting light between a first and a second end of the fibers and an outer covering allowing at least part of the light originating from the one or more elongated optical fibers to be transmitted through, a light source arranged in connection to the first end or to the second end of the fibers, and a power source.

A retractable leash assembly for an animal includes a first housing, a second housing, a cord member, and a retraction assembly. The first housing may be configured to be connected to a first collar. The second housing may be configured to be connected to a second collar. The cord member may be connected between the first housing and the second housing. The retraction assembly may be connected to the cord member. The first housing may include an opening configured to receive at least a portion of the second housing.

A handle having a gripping member. A base can be attached to a guidance device worn by an animal A retractable pulley assembly connects the base to the handle. A braking assembly has a trigger and a braking member. The retractable pulley assembly includes a spool, a wheel, an anchor, and a flexible member having a first end and a second end with the flexible member extending from the base to the handle, around the wheel, and to the anchor and with the flexible member being fixedly attached to the spool at the first end and to the anchor at the second end. The trigger actuates the braking member to frictionally engage the flexible member at an intermediate point between the flexible member first end and the flexible member second end to fix the distance between the handle and the base when the flexible member is pulled taut.

A retractable leash assembly and system is provided. The leash assembly includes a button that operates an inner lock to selectively prevent and allow rotation of a reel upon which a leash winds on and off. The leash assembly is compact, can be held on a pet and is easily operable by the user. The leash assembly includes a housing which doubles as a handle for the user to grasp, as well as the structure in which the leash is retained.

An illuminated strap assembly and a method for illuminating a strap assembly. The assembly includes a housing, a rotatable strap spool connected rotatably to the housing, a light emitting strap structure arranged to and fixed to the rotatable strap spool. The assembly includes a light source arranged to radiate light towards the rotatable strap spool and to illuminate the light emitting strap structure arranged to the rotatable strap spool.

An incorporated leash/collar is improved with the leash/collar strap. With a minimally stretchable strap, a buckle slides forms an adjustable collar with a first end of the strap. A metal buckle attached to the second end of the strap has a flat body with an opening. An adjustable position element has a post to engage the buckle body opening from either sides of the flat body. The first side engagement forms a leash handle loop in an operative configuration and the second side engagement maintain a wrap of the strap around the collar in a storage configuration. The incorporated leash/collar is also improved with a stretchable strap.
