Abstract

Claims (41)

1. A reel based closure device comprising:

a housing having an interior region;

a tension member having a first end and a second end positioned opposite the first end;

a spool positioned within the interior region of the housing, the spool being rotatable in a first direction to wind the tension member about the spool and the spool being rotatable in a second direction to unwind the tension member from about the spool; and

a knob that is operably coupled with the spool so that an operation of the knob causes the spool to rotate in the first direction within the interior region of the housing;

wherein:

the spool has an upper flange, a lower flange, and a cylindrical wall between the upper flange and the lower flange;

the tension member is wound about the cylindrical wall when the spool is rotated in the first direction; and

the cylindrical wall has three holes that are arranged so that the first end of the tension member is inserted through each of the three holes to secure the first end of the tension member to the spool.

2. The reel based closure device of claim 1 , wherein the reel based closure device further comprises one or more pawls that are configured to engage with teeth to prevent rotation of the spool in the second direction.

3. The reel based closure device of claim 2 , wherein the one or more pawls are components of a knob core that is operably coupled with the knob.

4. The reel based closure device of claim 2 , wherein the one or more pawls engage with the teeth when the knob is in an engaged position, and wherein the one or more pawls disengage from the teeth when the knob is in a disengaged position.

5. The reel based closure device of claim 4 , wherein the knob is moveable axially with respect to the housing between the engaged position and the disengaged position.

6. The reel based closure device of claim 1 , wherein the cylindrical wall further comprises an additional set of three holes through which the second end of the tension member is insertable to secure the second end of the tension member to the spool.

7. The reel based closure device of claim 1 , wherein the knob includes knob teeth that are configured to engage with spool teeth that are positioned on the upper flange of the spool.

8. The reel based closure device of claim 1 , wherein the spool has a depression on a side of the lower flange and wherein the first end of the tension member is located in the depression after the first end of the tension member is inserted through each of the three holes of the cylindrical wall.

9. The reel based closure device of claim 1 , wherein a diameter of the lower flange is smaller than a diameter of the upper flange.

10. An article of footwear, comprising the reel based closure device of claim 1 .

11. A spool that is positionable in an interior region of a housing of a reel based closure device, the spool being rotatable in a first direction upon an operation of a knob of the reel based closure device to wind a tension member about the spool, the tension member having a first end and a second end positioned opposite the first end, the spool comprising:

an upper flange;

a lower flange;

a cylindrical wall between the upper flange and the lower flange; and

a plurality of holes defined within the cylindrical wall;

wherein:

the tension member is windable about the cylindrical wall when the spool is rotated in the first direction; and

the plurality of holes are arranged in the cylindrical wall so that the first end of the tension member is insertable through each hole of the plurality of holes to secure the first end of the tension member to the spool.

12. The spool of claim 11 , wherein the cylindrical wall further comprises an additional plurality of holes through which the second end of the tension member is insertable to secure the second end of the tension member to the spool.

13. The spool of claim 11 , wherein the spool further comprises a depression on a side of the lower flange, and wherein the first end of the tension member is positionable within the depression after the first end of the tension member is inserted through the plurality of holes of the cylindrical wall.

14. The spool of claim 11 , wherein a diameter of the lower flange is smaller than a diameter of the upper flange.

15. The spool of claim 11 , wherein the spool comprises spool teeth that are positioned on the upper flange, and wherein the spool teeth are configured to engage knob teeth that are positioned on the knob.

16. The spool of claim 11 , wherein the plurality of holes consists of three holes defined within the cylindrical wall.

17. A reel based closure device comprising the spool of claim 11 .

18. A method of coupling a tension member to a spool, the method comprising:

providing the spool of claim 11 ; and

inserting the first end of the tension member through the plurality of holes of the cylindrical wall to secure the first end of the tension member to the spool.

19. A method of assembly a reel based closure device comprising:

coupling the tension member to the spool according to the method of claim 18 ; and

inserting the spool within the interior region of the housing of the reel based closure device.

20. A method of attaching a reel based closure device to an article of footwear, the method comprising:

assembling the reel based closure device according to the method of claim 19 ; and

attaching the reel based closure device to the article of footwear.
