Integrated closure device components and methods
A lace tensioning device includes a housing component having an interior region, a first aperture, and a second aperture, and a spool component that is rotatably positionable within the interior region of the housing component. The spool component has a central cylindrical member and a lumen that extends through the central cylindrical portion. The spool component is rotatable within the interior region of the housing component to align one end of the lumen with the first aperture and to align an opposite end of the lumen with the second aperture to enable a lace to be inserted through the first aperture, the lumen, and the second aperture so that opposing ends of the lace are positioned exterior to the housing component. A knot may then be tied in the lace and the lace retracted to couple the lace with the housing component and spool component.
1 . A reel based closure device comprising:
a base member having a cavity and an outer peripheral wall that surrounds the cavity;
a housing having an interior, the housing being mountable within the cavity of the base member;
a spool rotatably positioned within the interior of the housing;
a pawl comprising a cantilevered arm and one or more pawl teeth, the pawl being operably coupled with the spool to allow the spool to rotate in a first direction while preventing rotation of the spool in a second direction; and
a knob positioned axially above the spool and operably coupled therewith such that a rotation of the knob relative to the housing causes the spool to rotate in the first direction; wherein:
the housing includes lace ports;
the base member includes channels or openings in the outer peripheral wall that align with the lace ports of the housing when the housing is mounted within the base member;
the housing includes a single annular ridge;
the knob includes a plurality of radially protruding flanges; and
the plurality of radially protruding flanges of the knob is snap together couplable with the single annular ridge of the housing to couple the knob with the housing.

4 . The reel based closure device of claim 1 , wherein the pawl is configured to deflect radially inward to allow the spool to rotate in the first direction.
5 . The reel based closure device of claim 4 , wherein the knob is axially moveable or rotatable in the second direction to enable the spool to rotate in the second direction.
6 . The reel based closure device of claim 1 , wherein the reel based closure device further comprises a central boss that protrudes axially into the interior of the housing.
7 . The reel based closure device of claim 6 , wherein the central boss is at least partially positionable through an aperture in the spool so that the spool rotates about, or relative to, an axis of the central boss.
8 . The reel based closure device of claim 1 , wherein the housing includes inward facing ratchet teeth that are engageable with the pawl to allow the spool to rotate in the first direction while preventing the spool from rotating in the second direction.
9 . The reel based closure device of claim 1 , wherein the housing includes an open top end and an open bottom end.
10 . A reel based closure device comprising:
a base member having a cavity;
a housing having an interior, the housing being positionable within the cavity of the base member;
a spool rotatably positioned within the interior of the housing;
a driver including one or more cantilevered arms, the driver operably coupled with the spool to effect rotation of the spool in a first direction within the interior of the housing; and
a knob operably coupled with the driver such that a rotation of the knob relative to the housing causes the spool to rotate in the first direction; wherein:
the housing includes one or more lace ports;
the base member includes one or more channels or openings that align with the one or more lace ports of the housing when the housing is mounted within the base member;
the housing includes a single annular ridge;
the knob includes one or more radially protruding flanges; and
the one or more radially protruding flanges of the knob is snap together couplable with the single annular ridge of the housing to couple the knob with the housing.
11 . The reel based closure device of claim 10 , wherein when coupled together, the one or more radially protruding flanges is at least temporarily separable from the annular ridge by a gap.
12 . The reel based closure device of claim 10 , wherein the housing includes an open top end and an open bottom end.
13 . The reel based closure device of claim 10 , wherein the knob is operable to allow the spool to rotate in a second direction.
14 . The reel based closure device of claim 13 , wherein the knob is axially moveable or rotatable in the second direction to enable the spool to rotate in the second direction.
15 . The reel based closure device of claim 10 , wherein the reel based closure device further comprises a central boss that protrudes axially into the interior of the housing.
16 . The reel based closure device of claim 10 , wherein the housing includes inward facing ratchet teeth that are engageable with the one or more cantilevered arms to allow the spool to rotate in the first direction while preventing the spool from rotating in a second direction.
17 . The reel based closure device of claim 10 , wherein the one or more radially protruding flanges includes at least three radially protruding flanges.
18 . An article of footwear comprising:
a reel based closure device that is coupled with the article of footwear to tighten the article of footwear about a wearer's foot, the reel based closure device including:
a base member having a cavity;
a housing having an interior, the housing being positioned within the cavity of the base member;
a spool rotatably positioned within the interior of the housing;
a pawl comprising a cantilevered arm and one or more pawl teeth, the pawl being operably coupled with the spool to allow the spool to rotate in a first direction while preventing rotation of the spool in a second direction; and
a knob positioned axially above the spool and operably coupled therewith such that a rotation of the knob relative to the housing causes the spool to rotate in the first direction; wherein:
the housing includes one or more lace ports;
the base member includes one or more channels or openings that are aligned with the one or more lace ports of the housing;
the housing includes a single annular ridge;
the knob includes a plurality of radially protruding flanges; and
the plurality of radially protruding flanges of the knob is snap together couplable with the single annular ridge of the housing to couple the knob with the housing.
