Abstract
Slider assemblies and methods of manufacturing slider assemblies including a slider with a locking feature that cooperates with a plurality of coils of a standard zipper component. In some embodiments, the slider is capable of moving freely along the length of the zipper component when sufficient force is applied to the slider, but is capable of being locked in position when sufficient force is no longer applied to the slider. In certain embodiments, the locking feature is generally M-shaped. In some embodiments, the sliders are formed using injection molding techniques.
Claims12
A slider comprising:
- a channel dimensioned to receive at least partially a plurality of coils of a zipper component;
- a locking feature that is structurally integral with the slider, the locking feature having two angled portions and a bottom component positioned between the two angled portions and dimensioned to fit between the coils, wherein at least a portion of the locking feature is positioned within the channel to interact with the coils of the zipper component, and
- wherein the locking feature is configured so that, when sufficient force is applied to the slider in a first direction along the length of the zipper component, the locking feature allows the slider to move in the first direction along the length of the zipper component, and when sufficient force is applied to the slider in a second direction opposite to the first direction along the length of the zipper component, the locking feature allows the slider to move in the second direction along the length of the zipper component,
- wherein when the bottom component of the locking feature is received between the coils of the zipper component, a first of the two angled portions contacts one of the coils of the zipper component and a second of the two angled portions contacts an adjacent one of the coils of the zipper component to restrict the movement of the slider in both the first and second directions along the length of the zipper component until the sufficient force is applied to the slider in the first or second direction along the length of the zipper component, and
- wherein the two angled portions are positioned such that the two angled portions are arranged along the length of the zipper component when the slider is attached to the zipper component.

A slider assembly comprising:
- a slider comprising:
- a distal portion having a first opening;
- a channel configured to receive at least partially at least some of a plurality of coils of a zipper component;
- a locking feature at least a portion of which is positioned within the channel to engage at least some of the plurality of coils, the locking feature comprising an engaging portion positioned between two angled portions and two upper spacer portions;
- a second opening configured to receive at least part of a tape portion of the zipper component, wherein the channel is connected to the second opening and the second opening is located opposite the distal portion,
- wherein the locking feature is configured so that, when sufficient force is applied to the slider in a first direction along the length of the zipper component, the locking feature allows the slider to move in the first direction along the length of the zipper component, and when sufficient force is applied to the slider in a second direction opposite to the first direction along the length of the zipper component, the locking feature allows the slider to move in the second direction along the length of the zipper component,
- wherein the engaging portion of the locking feature is dimensioned to fit between at least some of the plurality of coils and a first of the two angled portions is dimensioned to contact one of the coils of the zipper component and a second of the two angled portions is dimensioned to contact an adjacent one of the coils of the zipper component to prevent the movement of the slider in both the first and second directions along the length of the zipper component when the engaging portion is positioned between two of the plurality of coils unless the sufficient force is applied to the slider in the first or second direction along the length of the zipper component,
- wherein the slider and the locking feature are structurally integral so that the slider and the locking feature form a single component, and
- wherein the two angled portions are positioned such that the two angled portions are arranged along the length of the zipper component when the slider is attached to the zipper component.
