Abstract
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.
Claims19
A lanyard comprising:
- a housing comprising an opening;
- a reel rotatably mounted within the housing;
- an elongate structure wound around the reel, the elongate structure having an inner end coupled to the reel and an opposing outer end extending out of the opening;
- a first coupling mechanism coupled to the outer end of the elongate structure;
- a second coupling mechanism coupled to the housing;
- a retraction system coupled to the reel, wherein the retraction system biases the elongate structure to be rewound onto the reel;
- and
- an arm coupled to the housing, the arm comprising a body, a first end of the body, and an opposing second end of the body, wherein the arm actuates between:
- a locked position in which the first end extends out of the housing and the second end does not extend out of the housing, the arm interfacing with the reel to bias the reel from rotating when the arm is in the locked position;
- and
- an unlocked position in which the second end extends out of the housing and the first end does not extend out of the housing, wherein the arm does not bias the reel from rotating when the arm is in the unlocked position.

- a reel rotatably mounted within the housing;
- an elongate structure wound around the reel, the elongate structure having an inner end coupled to the reel and an opposing outer end extending out of the opening;
- a first coupling mechanism coupled to the outer end of the elongate structure;
- a second coupling mechanism coupled to the housing;
- an arm slideably coupled to the housing, the arm actuating between a locked position and an unlocked position, the arm interfacing with the reel when in the arm is in the locked position to bias the reel from rotating;
- and
- an arm biasing system that biases the arm to remain in the locked position and that biases the arm to remain in the unlocked position.

A lanyard comprising:
- a housing;
- a reel rotatably mounted within the housing;
- an elongate structure wound around the reel, the elongate structure having an inner end coupled to the reel and an opposing outer end, the reel rotating in a first direction to retract the elongate structure into the housing, and the reel rotating in an opposing second direction when the elongate structure is being pulled from the housing;
- a first coupling mechanism coupled to the outer end of the elongate structure;
- an arm coupled to the housing, the arm actuating between a locked position and an unlocked position, the arm interfacing with the reel when in the arm is in the locked position to bias the reel from rotating in the second direction;
- and
- an arm lock mechanism that biases the arm to remain in the locked position, wherein the arm transitions from the locked position to the unlocked position in response to the elongate structure receiving a pulling force greater than a threshold amount of force.
