Abstract

A reel based closure device includes a housing, a tension member, a spool that is rotatably positioned within the housing, and a tightening component that is positioned axially above the spool and that is operably coupled therewith so that an operation of the tightening component causes the spool to rotate within the housing to wind the tension member about the spool. The reel based closure device also includes a coupling component that is separate from the tension member and that frictionally engages with a distal end of the tension member so that the coupling component is removably fixed to the tension member. The spool component includes a coupling feature within which the coupling component is positioned to attach the tension member to the spool.

First claim

What is claimed is:

1. A reel based closure system comprising:
a base member that defines an interior region;
a housing component that is positionable within the interior region of the base member and that is releasably coupleable with the base member;
a spool component rotatably positioned within the housing component, the spool component being configured so that a tension member is windable about the spool component;
a tightening component rotatably coupled with the housing component and operably coupled with the spool component such that an operation of the tightening component causes the spool component to rotate within the housing component to wind the tension member about the spool component and thereby tighten an article;
wherein the housing component is coupleable with the base member by axially inserting the housing component within the interior region of the base member and rotating the housing component relative to the base member; and
wherein the housing component is detachable from the base member without requiring a rotation of the housing component relative to the base member.

2. The reel based closure system of claim 1 , wherein the housing component is detachable from the base member upon application of a force to the housing component that causes the housing component to move axially out of the interior region of the base member.

3. The reel based closure system of claim 2 , wherein the housing component is detachable from the base member via a deflection of at least a portion of the base member.

4. The reel based closure system of claim 2 , wherein the base member includes one or more ports or channel within which a force application tool is positionable to apply the force to the housing component that causes the housing component to move axially out of the interior region of the base member.

5. The reel based closure system of claim 1 , wherein:
a bottom end of the housing component that is insertable within the interior region of the base member includes a plurality of radially extending tabs;
the base member includes a plurality of radially extending channels that align with the radially extending tabs to enable the housing component to be axially inserted within the interior region of the base member; and
rotation of the housing component relative to the base member causes each radially extending tab to be moved within a circumferential groove or channel and positioned under a lip or protrusion of the base member.

6. The reel based closure system of claim 5 , wherein at least one of the radially extending tabs of the housing component is configured to mechanically engage with an anti-rotation member of the circumferential groove or channel of the base member to prevent a counter rotation of the housing component relative to the base member and thereby secure the housing component within the interior region of the base member.

7. The reel based closure system of claim 1 , wherein the base member and the housing component are configured so that the housing component must be aligned with the base member in one of a few defined orientations in order to couple the housing component with the base member.

8. The reel based closure system of claim 7 , wherein the base member and the housing component are configured to prevent rotation of the housing component relative to the base member when the housing component is axially inserted within the interior region of the base member in an orientation other than one of the few defined orientations.

9. A reel based closure system comprising:
a base member that defines an interior region;
a housing component that is positionable within the interior region of the base member and that is releasably coupleable with the base member;
a spool component rotatably positioned within the housing component, the spool component being configured so that a tension member is windable about the spool component;
a tightening component rotatably coupled with the housing component and operably coupled with the spool component such that an operation of the tightening component causes the spool component to rotate within the housing component to wind the tension member about the spool component;
wherein the housing component is rotatable relative to the base member to secure the housing component within the interior region of the base member; and
wherein the housing component is axially moveable relative to the base member to detach the housing component from the base member without requiring a rotation of the housing component relative to the base member.

10. The reel based closure system of claim 9 , wherein the housing component is axially moveable relative to the base member upon application of a force to the housing component that would damage the housing component absent detachment of the housing component from the base member.

11. The reel based closure system of claim 9 , wherein the housing component is axially moveable relative to the base member via a deflection of at least a portion of the base member.

12. The reel based closure system of claim 9 , wherein the base member includes one or more ports or channel within which a force application tool is positionable to apply a force to the housing component that causes the housing component to move axially relative to the base member.

13. The reel based closure system of claim 9 , wherein the base member and the housing component are configured to prevent rotation of the housing component relative to the base member unless the housing component is aligned with the base member in a defined orientation.

14. A method of assembly of a reel based closure system comprising:
providing a reel based closure system comprising:
a base member that defines an interior region;
a housing component;
a spool component rotatably positioned within the housing component; and
a tightening component rotatably coupled with the housing component and operably coupled with the spool component to cause the spool component to rotate within the housing component upon an operation of the tightening component;

axially inserting a bottom end of the housing component within the interior region of the base member; and
rotating the housing component relative to the base member to secure the housing component about the base member;
wherein the housing component is detachable from the base member without requiring a counter rotation of the housing component relative to the base member.

15. The method of claim 14 , wherein the housing component is detachable from the base member upon application of a force to the housing component that causes the housing component to move axially out of the interior region of the base member.

16. The method of claim 15 , wherein an axial movement of the housing component relative to the base member requires a deflection of at least a portion of the base member.

17. The method of claim 14 , wherein the base member includes one or more ports or channel and wherein the method further comprises inserting a force application tool within the one or more ports or channels and applying a force to the housing component via the force application tool to cause the housing component to move axially relative to the base member.

18. The method of claim 14 , wherein:
axially inserting the bottom end of the housing component within the interior region of the base member comprises inserting a plurality of radially extending tabs of the housing component within corresponding radially extending channels of the base member; and
rotation of the housing component r
