Systems, methods, and apparatus related to a homing mechanism within a drive mechanism of a lacing engine for an automated footwear platform are described. In an example, the homing apparatus 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.

A line retraction device includes a rotatable drum having a line associated therewith, with the line including a first end directly or indirectly attached to the drum and a second end opposite the first end, and at least one retraction member biasing the drum in a first rotational direction of the drum opposite a second rotational direction of the drum, where the drum is configured to: (i) retract the line when the drum moves in the first rotational direction; and (ii) payout the line when the drum moves in the second rotational direction. The device further including a damper assembly configured to provide rotational resistance to the drum in: (i) the first rotational direction of the drum as the line is being retracted; and (ii) the second rotational direction as the line is being paid out.

The invention is a collapsible cord wrapping device for clipping onto the cords of earbuds or similar devices when in use, which device can be unfolded for use as a cord wrapping base during earbud storage to prevent tangling.

The present invention discloses a winding device that includes a screen, a shaft portion to which one end of the screen is fastened, a rotary shaft member that fits to an end portion of the shaft portion so that the rotary shaft member is rotated around a rotation axis along an axial direction of the shaft portion, and a biasing portion that biases the rotary shaft member in a rotation direction for winding the screen. A relative rotation restriction structure and a movement restriction structure are formed on a fitting portion between the shaft portion and the rotary shaft member. The relative rotation restriction structure restricts a relative rotation of the shaft portion with respect to the rotary shaft member. The movement restriction structure restricts a movement of the shaft portion in the axial direction with respect to the rotary shaft member.

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

A pull-out type cord winding module, comprising a rotary wheel (6) which a cord (7) is wound on and which is connected with a coil spring (5), and a stopper mechanism working cooperatively with the rotary wheel (6) and including a functional rail, a ball (3) and a rolling assisting device. The functional rail comprises a locking rail, a communicating rail (25) and annular rails (21, 22) which are connected, groove-shaped and arranged around an outer circumference of the rotary wheel (6). A guide groove (91) is provided on the rolling assisting device, and two ends of the guide groove (91) are located at the upper and lower sides of the outer circumference of the rotary wheel (6) respectively. The guide groove (91) cooperates with the functional rail to hold the ball (3). When the rotary wheel (6) rotates, the ball (3) rolls in the functional rail to lock or unlock rotation of the rotary wheel (6).

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.

Apparatus and methods are disclosed of a welding-type system includes a welding-type power supply configured to provide welding-type power. A reel located within a housing of the welding-type power supply. A welding-type cable, the reel configured to wind the welding-type cable to reduce a length of the welding-type cable extending from the housing, and to unwind to increase a length of the welding-type cable extending from the housing at least partially wound around the reel when stored. The welding-type cable includes a first end secured to the reel and electrically connected to the welding-type power supply and a second end configured to provide the welding-type power to at least one welding-type tool.

A pet toy apparatus is provided. The apparatus includes a housing having a bracket for mounting the apparatus onto a structure. A biased reel rotatably disposed in the housing includes an elongated tether wound thereabout. A quick release mechanism disposed on an end of the tether and positioned exterior to the housing is configured to interchangeably receive a pet toy. Rotation of the reel in a first direction winds and retracts the tether into the housing, while rotation of the reel in an opposing second direction unwinds and extends the tether out of the housing. The reel is biased in the first direction so as to tensionably rotate back in the first direction after being rotated in the second direction, thereby automatically retracting the tether. A stopper slidably disposed along the tether is configured to prevent retraction of the tether into the housing.

A telephone wire withdrawing device, which is used for achieving the drawing and withdrawing functions of a telephone wire, enabling a smooth operation, thereby improving the usage experience of a user, and avoiding call distortion caused by using an electric brush because it is unnecessary to use the electric brush. The telephone wire withdrawing device in the application includes a slide block, a machine frame, a microphone, a telephone wire, a first roller, a rotating self-locking mechanism, a second roller and an extension spring, wherein the rotating self-locking mechanism is composed of a base, a gear shell, a paddle, a first resilient sheet and a second resilient sheet.
