Abstract

A cord lock includes various components used to slidably adjust a cord length, such as one or more housing components that releasably clamp around the cord. In one aspect, the cord lock includes an arrangement of magnets that bias the cord-lock housing components away from one another, in order to secure the cord between the housing components. The housing components can be pressed towards one another to slidably adjust the cord. In a further aspect, the cord lock may also include a magnetized excess-cord retainer that attaches to a portion of the cord and that releasably attaches to the cord lock in order to help gather excess cord pulled through the cord lock.

First claim

The invention claimed is:

1. A cord lock comprising:
a housing having a base and one or more sidewalls extending from the base to at least partially define a plunger-receiving space, the one or more sidewalls including a first through-channel, the housing including a first magnet that has a first pole with a first polarity and a second pole with a second polarity and that is positioned in the plunger-receiving space; and
a plunger including a second through-channel that is alignable with the first through-channel when the plunger is positioned in the plunger-receiving space, the plunger having a second magnet that has a third pole with a first polarity and a fourth pole with a second polarity, wherein the first polarity of the first pole and the first polarity of the third pole are a same polarity, and wherein the first pole and the third pole are oriented towards each other, such that the first polarity of the first pole and the first polarity of the third pole bias the second magnet away from the first magnet to dealign the first through-channel and the second through-channel.

2. The cord lock of claim 1 , wherein the first through-channel comprises first and second through-holes on opposite sides of the one or more sidewalls of the housing, and the second through-channel comprises first and second through-holes on opposite sides of the plunger.

3. The cord lock of claim 1 , wherein the housing and the plunger are movably coupled to each other.

4. The cord lock of claim 1 , wherein the first magnet is positioned within a volume defined by the one or more sidewalls of the housing and the second magnet is positioned at least partially inside the plunger.

5. The cord lock of claim 1 , wherein the plunger is
physically distinct from the housing.

6. The cord lock of claim 1 , further comprising a cord-retention cap.

7. The cord lock of claim 6 , wherein the cord-retention cap includes at least one through-channel.

8. The cord lock of claim 1 , wherein the first magnet is 10 Gauss or less.

9. The cord lock of claim 1 , wherein the base of the housing has a greater surface area along a first plane defined by a major surface than a surface area of the plunger-receiving space in a parallel plane to the first plane.

10. The cord lock of claim 1 , wherein the first and second magnets are between the first and second through-channels and the base when the first and second through-channels are aligned.

11. The cord lock of claim 1 , wherein the first and second magnets are on opposite sides of the first and second through-channels when the first and second through-channels are aligned.

12. An article comprising:
an article layer having a first surface and a second surface;
a first connection component affixed to the first surface of the article layer;
a cord lock comprising:
a housing having a base and one or more sidewalls extending from the base to at least partially define a plunger-receiving space, the one or more sidewalls having a first through-channel, the housing including a first magnet that has a first pole with a first polarity and a second pole with a second polarity and that is positioned in the plunger-receiving space, and a second connection component affixed to the base of the housing, and
a plunger having a second through-channel that is alignable with the first through-channel when the plunger is positioned in the plunger-receiving space, the plunger having a second magnet that has a third pole with a first polarity and a fourth pole with a second polarity, wherein the first polarity of the first pole and the first polarity of the third pole are a same polarity, and wherein the first pole and the third pole are oriented towards each other, such that the first polarity of the first pole and the first polarity of the third pole bias the second magnet away from the first magnet to dealign the first through-channel and the second through-channel, wherein the first and second connection components are coupled to secure the cord lock to the article layer; and

a cord positioned in the first and second through-channels.

13. The article of claim 12 , wherein the article is an item of apparel, a bag, or an item of footwear.

14. The article of claim 12 , wherein the first connection component is releasably secured to the second connection component.

15. The article of claim 12 , further comprising a cord-retention cap coupled to the cord.

16. The article of claim 12 , wherein the plunger is
physically distinct from the housing.

17. A cord lock comprising:
a housing having a base and one or more sidewalls extending from the base to at least partially define a plunger-receiving space, the one or more sidewalls including a first through-channel, the housing including a first magnet that has a first pole with a first polarity and a second pole with a second polarity and that is positioned in the plunger-receiving space, and an article mounting mechanism secured to the base;
a plunger including a second through-channel that is alignable with the first through-channel when the plunger is positioned in the plunger-receiving space, the plunger having a second magnet that has a third pole with a first polarity and a fourth pole with a second polarity, wherein the first polarity of the first pole and the first polarity of the third pole are a same polarity, and wherein the first pole and the third pole are oriented towards each other, such that the first polarity of the first pole and the first polarity of the third pole bias the second magnet away from the first magnet to dealign the first through-channel and the second through-channel; and
a cord-retention cap.

18. The cord lock of claim 17 , wherein the plunger is
physically distinct from the housing.

19. The cord lock of claim 17 , wherein the cord-retention cap is shaped to engage the plunger.
