A weight retraction device for use with a waterfowl decoy includes a housing having a spool rotatably coupled thereto. A weight is attached to a line that is wound around the spool. Rotation of the spool in a first rotational direction causing an unwinding of the line from the spool to cause the weight to extend away from the housing while rotation of the spool in a second rotational direction causing a rewinding of the line back onto the spool to cause the weight to retract back towards the housing. A power spring is configured to urge the spool to rotate in the second rotational direction. A lock release mechanism is configured to normally be in a locked configuration for preventing an undesired rotation of the spool in the second rotational direction. A manual actuation of the lock release mechanism releases the locked configuration of the lock release mechanism.

A lanyard having a locking mechanism is provided. The lanyard locking mechanism actuates between a locked position and an unlocked position. In the locked position, the lanyard spool is restricted from rotating, and in the unlocked position, the lanyard spool is permitted to rotate with reduced interference from the locking mechanism. The locking mechanism includes biasing components that bias the locking mechanism to remain stationary unless sufficient force is exerted.

an improved type of cable reel structure is disclosed, in which a sufficiently thick cable is used, which facilitates an operation of winding or unwinding the cable and which can prevent the cable from being twisted or disturbed in a repeated cable storage or withdrawal process and from being reduced in operability.

A pawl-less retractable comprises an inner frame with a drum-sperrad assembly mounted to the inner frame between side members of the frame to rotate relative to the frame and a stop cap which, during a fall, engages said drum-sperrad assembly to prevent further rotation of said drum. The inner frame can be pivotally mounted to the stop cap such that the inner frame and the drum-sperrad assembly pivot relative to the step cap, or the stop cap can pivot relative to the drum-sperrad assembly. The stop cap comprises a central body, a leading wing extending from a first side of the central body and a trailing wing extending from a second side of the central body opposite said first side. In use, the drum-sperrad assembly and the stop cap pivot relative to each other between an unlocked position in which the teeth of the sperrad are inside of an engagement zone circle and a locked position in which the teeth are outside of the engagement zone circle.

A retractor assembly includes a housing, a cover, a rotary plate, a swing arm, an outlet pipe, and an elastic drive member. The housing includes a cavity. The rotary plate is pivotally mounted within the cavity. The swing arm is pivotally mounted and includes a guide protrusion. The elastic drive member is configured to bias the rotary plate toward a reset position. A side of the rotary plate includes an outer guide groove and in inner guide groove. A first channel and a second channel span between the outer guide groove and the inner guide groove. The guide protrusion is configured to enter the inner guide groove from the outer guide groove via the first channel, and enter the outer guide groove from the inner guide groove via the second channel. The second channel includes a locking groove therein configured to catch the guide protrusion.

A winding mechanism includes a housing, an inner cylinder and a wire. The housing is formed with an accommodating space therein. An inner surface of the housing is formed with an internal thread structure. The inner cylinder is disposed in the accommodating space and defines a central axis. An outer surface of the inner cylinder is formed with an external thread structure. The external thread structure is cooperated with the internal thread structure. The inner cylinder is capable of displacing along the central axis by rotating relative to the housing. The external thread structure includes at least two contact portions and at least two non-contact portions, and gaps are formed between the non-contact portions of the external thread structure and the internal thread structure. An end of the wire is connected to the inner cylinder and is wound along the external thread structure of the inner cylinder.

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.

A temporary horizontal lifeline device includes a main frame, a central shaft pivotally arranged on the main frame, a drum and an external gear affixed on the central shaft, a spanner adapted for driving the central shaft to rotate, and a cable member winded around the drum. A gear groove is arranged on the periphery of the external gear. A first spring is arranged on the main frame so as to provide a force to enable the drum to retrieve the cable member. The main frame also comprises a brake element and a detent provided thereon. The brake element has a first state for restrict the gear groove and a second state for releasing the gear groove, which prevents the external gear from rotating forward and backward when the external gear is in the first state. The detent has a first position to mesh the gear groove and a second position to release the gear groove, so that the external gear is only allowed to unidirectionally rotate in the first position. Accordingly, the present invention is convenient and safe to use when conducting retrieving operation, and effectively improves the stress concentration issue of conventional detents.

A cable adjuster contains a gear shaft, a base, a rotatable disc, and a cable. The gear shaft includes a first column, a second column, a circular peg, and a threaded orifice. The base includes a first fixer and a second fixer. The first fixer has a first groove, and the second fixer has a second groove. An accommodation chamber is defined between the first groove and the second groove, the first fixer has a toothed notch and a circular notch, and the second fixer has a hollow shoulder, two T-shaped slots, and two holders. The rotatable disc includes a fixing orifice, a cylinder, and a recess. A head of the cable is received in the second fixer via the two T-shaped slots and is engaged in the recess so that an extension is fixed in one holder, and the rotatable disc is received in the second groove.

A microwave cooking appliance having power management. The appliance may include at least one cord positionable between at least one stowed position to at least one deployed position. The appliance may include one or more strain relief members stopping the deployment of the cord. The microwave cooking appliance may include a cord housing. The microwave cooking appliance may include a pulley engaging the cord. The microwave cooking appliance may include a biasing member engaging the pulley and/or cord. The microwave cooking appliance may include a pin and slot engagement engaging the pulley and/or cord.
