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.

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.

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.

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 retractable leash device (10, 53) for rolling up and unrolling a leash (13), especially for leading an animal, includes a leash roller (22) mounted rotatably on a carrier and a resetting device to reset the leash into a rolled-up position, in which the leash is wound up onto a leash roller. A blocking feature blocks the unrolling of the leash. A transmission is coupled to the leash roller and brings about blocking when a predetermined leash length is unrolled from leash roller. A simple configuration with high operating reliability and low wear is provided with the transmission having a first transmission element arranged rotatably on the carrier and a second transmission element arranged nonrotatably on the carrier. The first transmission element and the second transmission element have an outer circumference and an inner circumference associated with one another, which mesh with one another at least in an active state.

A device used to release, retract and store a cable or a cable-like structure provides an easy way for cable or cable-like structure applications. The device can be widely used for all kind electronic devices in private homes and in public facilities tidily and safely. By apply the devices in present patent application, there will significantly reduce safety hazards and solve problems related to cable messing up or winding each other around electrical devices.

A homing mechanism within a drive mechanism of a lacing engine for an automated footwear platform can include an indexing wheel, a plurality of Geneva teeth and a stop tooth. The plurality of Geneva teeth can be distributed around a portion of a perimeter of the indexing wheel. Each Geneva tooth of the plurality of Geneva teeth can include side profiles conforming to a first side profile that generates a first force when engaged by an index tooth on a portion of the drive mechanism. The stop tooth can be located along the perimeter of the indexing wheel between two Geneva teeth. Additionally, the stop tooth can include side profiles conforming to a second side profile that generates a second force when engaged by the index tooth.

The current invention concerns an improved motorized cable reel, specifically for a more stable and safer winding of the cables therearound.

A dual-web retractor includes a frame having spaced-apart sidewalls, a spool rotatably mounted between the sidewalls, a pair of engagement members configured to be releasably engaged to one another, and a single web having opposite ends each coupled to a different one of the pair of engagement members and a portion of the single web between the opposite ends affixed to the spool to define a first web section extending from one end of the frame between the spool and one of the pair of engagement members and a second web section extending from an opposite end of the frame between the spool and the other of the pair of engagement members. Rotation of the spool in a web take up direction alternatingly wraps the web sections onto the spool and rotation of the spool in a web pay out direction alternatingly unwraps the web sections from the spool.
