Lacing system methods and apparatuses
Abstract
The present invention is a lace locking system that eliminates
the inconveniences of a conventional lacing system. The design
reroutes laces behind the ankle to a "T pull" handle that
incorporates a "lace lock" that allows length adjustment to the
laces. When the "T-pull" handle is pulled upon, the laces cinch and
the handle is then placed into its rest. This provides the user
with a "memory lace system" so the laces do not have to be adjusted
and tied every time a shoe or skate is placed onto a foot.

Description
FIELD OF THE INVENTION
[0001] The present invention relates to lacing systems and, more
particularly, to methods and apparatuses allowing footwear to be
laced and unlaced.
BACKGROUND OF THE INVENTION
[0002] Generally speaking, the prior art teaches many different
lace systems for footwear. Most conventional lace systems, however,
require a tightening of the laces for use and a loosening of the
laces for removal of the footwear. Commonly, pulling and tying the
laces of the footwear accomplish the tightening and loosening. Some
footwear, however, include lace locks that replace the tying part
of the system. U.S. Pat. No. 6,192,559, issued on Feb. 27, 2001,
incorporated herein by reference, describes some conventional
shoelace fastening apparatuses.
[0003] While a variety of devices have been developed for lacing
systems, most are overly complex or require adept manual dexterity.
Further, most lacing systems eliminate the need to tie the laces,
but still require that the laces tightened and loosened manually.
Also, removing the footwear requires releasing the laces from the
lace locks.
[0004] Thus, it would be desirous to provide an improved lacing
system.
SUMMARY OF THE INVENTION
[0005] To attain the advantages and in accordance with the purpose
of the invention, as embodied and broadly described herein, an
article of footwear having a lacing system is provided. The article
of footwear includes a foot section having opposing sides and a
cuff section. At least one lace is woven between the opposing
sides. A pull having at least one lace lock is couple to the cuff
section such that when the at least one lace lock can be positioned
in a tightened position.
[0006] The foregoing and other features, utilities and advantages
of the invention will be apparent from the following more
particular description of a preferred embodiment of the invention
as illustrated in the accompanying drawings,

DETAILED DESCRIPTION
[0015] The present invention will now be described with reference
to FIGS. 1-7. Referring to FIG. 1, an in-line skate 1 is shown.
While the present invention will be described with reference to
in-line skates, one of ordinary skill in the art will recognize on
reading the disclosure that the present invention could be used in
a variety of footwear, such as, ice skates, hiking boots, tennis
shoes, basketball shoes, sneakers, biking shoes, and the like.
Further, while shown with regard to conventional footwear, the
present invention could also be used with footwear having
adjustable sizes, such as, for example, U.S. Pat. No. 6,471,219,
titled ADJUSTABLE FIT IN-LINE SKATE, issued on Oct. 29, 2002, U.S.
Pat. No. 6,402,163, titled, ADJUSTING THE SIZE OF A LINED SPORT
BOOT, issued on Jun. 11, 2002, U.S. Pat. No. 6,374,516, titled BOOT
WITH AN ADJUSTABLE LENGTH UPPER ADAPTED FOR SKATING, issued Apr.
23, 2002, and the like, all incorporated by reference.
[0016] In-line skate 1 includes a boot portion 2 and a frame
portion 3. Frame portion 3 conventional includes, not labeled as
the parts are conventional, a wheel chassis, which typically
includes an inverted "U" shape section to hold a plurality of
wheels, a longitudinal surface to attach boot portion 2 to frame
portion 3. While not shown, frame portion 3 may also include a
conventional in-line skate brake.
[0017] Boot portion 2 generally includes foot section 4 and a cuff
section 5. A liner 6 may line the inside of boot portion 2. Foot
section 4 has a lace system 7, which is shown in more detail in
FIG. 2. Lace system 7 includes lace guides 8 and lace 9. Lace
guides 8 can be clamp style guides as shown, loops, ringlets, or
the like. Lace guides 8 allow lace 9 to be woven between opposing
sides 10 of foot section 4 such that tightening lace 9 causes
opposing sides 10 of foot section 4 to fit snuggly around a foot of
a user.
[0018] Referring back to FIG. 1, unlike conventional in-line
skates, lace guides 8 provide a lace path for lace 9 such that the
lace wraps around cuff portion 5 and attaches to a pull 11. A
possible pull 11 is shown in more detail in FIG. 3. Attaching lace
9 to pull 11 allows for locking lace 9 so opposing sides 10 can be
in a snug position around the foot of a user. While conventionally
lace 9 has a first end and a second end (not shown or labeled) to
facilitate tying lace 9, the present invention is such that a
continuous loop lace could be used.
[0019] Referring now to FIG. 3, pull 11 can be seen in more detail.
Pull 11 includes a lace lock 13 and a rest 12. Rest 12 is attached
to the cuff section 5. As shown, lace lock 13 is releasably coupled
to rest 12. Lace lock 13 has a release button 14. Depressing
release button 14 will reduce the friction holding lace 9 in the
tightened position. Use of the lace lock 13 will be explained with
respect to flowchart 600 below. Referring to FIG. 4, a rear view of
lace lock 13 is shown. As shown in FIG. 4, lace lock 13 can have
one or more horizontal extension 13h and one or more vertical
extensions 13v. The configuration or shape of lace lock 13 is
largely a matter of design choice, but at least one horizontal
extension 13h and at least one vertical extension 13v makes it
easier to pull pull 11 into a tightened position. Once in the
tightened position, rest 11 (or cradle lock) can hold lace lock 13
with lace 9 locked in the tightened position. Referring now to FIG.
5, a cross sectional view of lace lock 13 is shown. As shown if
FIG. 5, lace lock 13 has a lace through hole (not shown or
labeled). Release 14 has a release through hole 15 and a bias 16,
such as a spring. In the lock position, bias 16 exerts a force on
release 14 such that hole 15 pinches lace 9 (not shown in FIG. 5)
against lace lock 13 sufficiently such that the friction locks lace
9 in place. Pressing release 14 against bias 16 releases the
friction such that lace lock 13 can freely slide up and down lace
9. Of course other releases are possible, with a spring-biased
actuator being a cost effective release.
[0020] FIG. 6 shows a flowchart 600 representative of a first
tightening of in-line skate 1 using the present invention. First,
lace 9 is tightened, step 602. Next lace 9 is attached to lace lock
13 to lock lace 9, step 604. Finally, lace lock 13 is releasably
connected to rest 12 such that pull 11 is in the tightened
position. As can be seen in this example, lace lock 13 is treaded
or slid down lace 9 until pull 11 achieves the tightened position
using a releasable connection. FIG. 7 shows an alternative pull 17.
Alternative pull 17 has rest 12 and lace lock 13. Lace lock 13,
however, is pivotally connected to rest 12 by pivot 18 and
extension 19. Alternative pull 17 is shown in the loosened
position. To tighten the footwear, pull 17 would pivot extension 19
upwards to a tightened position. If a pivot style pull were used,
step 606 would be pivot pull 17 into the tightened position or the
like. Notice, one of skill in the art will now recognize
alternative embodiments of the pull and the above two examples
should be viewed as illustrative and not limiting.
[0021] Once the first tightening is complete, the loosening and
re-tightening of in-line skate one is accomplished by releasably
detaching lace lock 13 from rest 12 to loosen and releasably
attaching lace lock 13 to rest 12. Because lace lock 13 has
previously been positioned on lace 9, attaching lace lock 13 to
rest 12 automatically and properly tightens the footwear providing
a memory lace system of sorts. Of course, release 14 could be
actuated to re-position lace lock 13 on lace 9 as frequently as the
user desires. Similarly, alternative pull 17 would be moved from
the tightened position to the loosened position by pivoting pull
17. Again providing a memory lace system for the footwear.
[0022] While the invention has been particularly shown and
described with reference to some embodiments thereof, it will be
understood by those skilled in the art that various other changes
in the form and details may be made without departing from the
spirit and scope of the invention.
