Patent ID: 8424169

Claim:
A cord lock assembly configured to selectively tighten and loosen a draw cord of an article, the cord lock assembly comprising: a shell defining an interior chamber, said shell comprising aligned shell cord surfaces; a piston slidably retained within said interior chamber, said piston comprising a piston cord passage formed therethrough; a spring member that exerts a biasing force into said piston within said shell so that said piston cord passage is misaligned with respect to said shell cord surfaces in a locked position, wherein said shell is configured to be pulled via a pulling action with respect to said piston, or vice versa, to compress said spring member so as to align said piston cord passage with said shell cord surfaces in an unlocked position so that a draw cord may freely pass therethrough, wherein upon release of the pulling action, the biasing force of said spring member causes said piston to move back to said locked position; and at least one anchor configured to securely retain a portion of material that is secured to the article.
