Reel based closure system
Disclosed is a closure system used in combination in any of a variety of applications including clothing, for example as a footwear lacing system comprising a lace attached to a tightening mechanism. The lace extends through a series of guide members positioned along two opposing footwear closure portions. The lace and guides preferably have low friction surfaces to facilitate sliding of the lace along the guide members so that the lace evenly distributes tension across the footwear member. The tightening mechanism allows incremental adjustment of the tension of the lace. The closure system allows a user to quickly loosen the lace and inhibits unintentional and/or accidental loosing of the lace.
1. A footwear lacing system, comprising:
a footwear member including first and second opposing sides separated by a tongue portion of the footwear member;
a lace guided along a path of the footwear member and having opposing ends coupled with a spool;
a tightening mechanism attached to the footwear member and operationally coupled to the spool, wherein operation of the tightening mechanism effects winding of the lace about the spool to tension the lace and tighten the footwear member, the tightening mechanism being positionable in an engaged position and a disengaged position, the tightening mechanism including a housing having a pair of lace ports, wherein:
in the engaged position, rotation of the tightening mechanism in a first direction effects rotation of the spool in the first direction to wind the lace about the spool; and
in the disengaged position, the spool is freely rotatable in a second direction to loosen the lace; and
first, second, and third guide members attached to the footwear member, each guide member having a channel formed therein with an opening that enables a closed loop of the lace to be positioned within the channel without requiring the lace to be threaded through the channel, each guide member being coupled with the footwear member so that the opening of the channel faces away from a midline of the footwear member so that, under tension, the lace is retained within the channel of the respective guide member, each guide member including one or more retention members that partially close the opening of the channel to prevent the lace from escaping when tension on the lace is released;
wherein the channel of each guide member comprises an elongated longitudinal lace pathway extending generally parallel to a longitudinal axis of the footwear member and first and second lace entrance points positioned on opposing ends of the lace pathway where the lace enters or exits the lace pathway;
wherein the lace slidably extends along the first and second lace entrance points and the longitudinal lace pathway of each guide member; and
wherein the path of the footwear member along which the lace is guided is defined by and consists of the tightening mechanism, the first guide member, the second guide member, and the third guide member, wherein the tightening mechanism and the first guide member are positioned on the first side of the footwear member, and the second guide member and the third guide member positioned on the second side of the footwear member, and wherein the path is configured such that the lace forms an acute angle from the lace ports of the tightening mechanism across the tongue portion of the footwear member.
2. The footwear lacing system of claim 1 , wherein the opening of the channel comprises a semicircular, “C” shaped, or “U” shaped cross section.
3. The footwear lacing system of claim 1 , wherein each guide member includes a flange that aids in coupling the guide members with the footwear member, wherein the flange extends from the first lace entrance point and along the channel to the second lace entrance point.
4. The footwear lacing system of claim 1 , wherein the tightening mechanism includes a rotatable knob that is configured for grasping by a user's hand.
5. The footwear lacing system of claim 4 , wherein the tightening mechanism is moved between the engaged position and the disengaged position by operation of the knob.
6. A lacing system for footwear, comprising:
a lace having opposing ends coupled with a spool;
a tightening mechanism attached to the footwear and operationally coupled to the spool, the tightening mechanism being configured to effect winding of the lace about the spool to tension the lace and tighten the footwear, the tightening mechanism being moveable between an engaged position and a disengaged position, wherein:
in the engaged position, rotation of the tightening mechanism in a first direction effects rotation of the spool in the first direction to wind the lace about the spool; and
in the disengaged position, the spool is freely rotatable in a second direction to loosen the lace; and
first, second, and third guide members attached to the footwear and configured to guide or direct the lace along a lace path about the footwear, wherein the first guide member includes a channel with an opening formed therein that enables a closed loop of the lace to be positioned within the channel without requiring one of the opposing ends of the lace to be threaded through the channel, the first guide member being positionable on the footwear so that the opening of the channel faces away from a midline of the footwear such that, under tension, the lace is retained within the channel, the first guide member including one or more retention members that partially close the opening of the channel to prevent the lace from escaping when tension on the lace is released;
wherein the lace path is defined by and consists of the tightening mechanism, the first guide member, the second guide member, and the third guide member, wherein the tightening mechanism and the second guide member are positioned on the first side of the footwear, and the first guide member and the third guide member are positioned on a second side of the footwear, and wherein the lace path is configured such that the lace forms an acute angle across a tongue portion of the footwear.
7. The lacing system of claim 6 , wherein the opening of the channel comprises a semicircular, “C” shaped, or “U” shaped cross section.
8. The lacing system of claim 6 , wherein the first guide member includes a first lace entrance point, a second lace entrance point, and a flange that aids in coupling the first guide member with the footwear, wherein the flange extends from the first lace entrance point and along the channel to the second lace entrance point.
9. The lacing system of claim 6 , wherein the tightening mechanism includes a rotatable knob that is configured for grasping by a user's hand.
10. The lacing system of claim 9 , wherein the tightening mechanism is moved between the engaged position and the disengaged position by operation of the knob.
11. The lacing system of claim 6 , wherein the second guide member and the third guide member each include a channel configured similar to that of the first guide member.
