Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to snowboards, and in
particular, a positioning system for a snowboard.
[0003] 2. Description of the Related Art
[0004] Snowboarding is a relatively new sport which can be compared
to skateboarding or surfing, on snow. To snowboard, the rider
stands on a board with his/her left or right food forward, facing
one side of the board. The feet are attached to the board via
bindings.
[0005] Snowboarding has gained in popularity only during the last
15 years. It was pioneered in the late 1970's by a small group of
individuals with credit typically going to Jake Burton and Tom
Sims. The roots, however, started with the "snurfer" which was a
sledding toy shaped like a small water ski, with rope tied to the
back where the user stood. Burton was involved with snurfer racing
and was the first to put a retention device on his boards.
[0006] Snowboarding is now prevalent on virtually all downhill ski
slopes worldwide. In 1985 only 7 percent of ski areas allowed
snowboards; today more than 90 percent allow snowboards, and over
half have specialized snowboard areas referred to as half pipes. A
half pipe is a trough cut or built up with snow, with the term
originating from skateboarding. Today about 10 percent of the world
skier population comprises snowboarders, with the annual growth
rate for the sport projected at 20 percent. In the United States,
about 80 percent of snowboarders are male with an average age of
20.8 years. The average snowboarder rides 15 days a year, which is
3 times that of the average skier.
[0007] Two types of bindings are commonly used in snowboarding: the
high-back and the plate. The high-back is characterized by a
vertical plastic back piece which is used to apply pressure to the
heel-side of the board. The binding has two straps which go over
the foot, with one strap holding down the heel and the other
holding down the toe. Some high-backs also have a third strap on
the vertical back piece called a shin strap which gives additional
support and aids in toe side turns. The plate, or step-in binding,
is used with a hard shell boot much like a ski binding, except that
it is non-releasable.
[0008] For different events, the desired angle of the binding
relative to the longitudinal axis of the board might need to be
changed. For instance, during speed runs, such as Giant Slalom (GS)
the typical snowboarder would prefer to have his feet oriented more
relatively straight ahead. For other events, such as freestyle, the
desired angle would be oriented more perpendicular to the
longitudinal axis. From Transworld Snowboarding the average stances
of pro riders from different disciplines are as follows, with width
in inches, angles in degrees, with 0 degrees being perpendicular to
the longitudinal axis, center being inches back from the
longitudinal of the board center, and board length in cm:
1 stance width front angle rear angle center board length Half-pipe

170.5 Slope Style 21.3 12 0 1 152.9
[0009] Current standard snowboard positioning systems include a
rectangular four hole or triangular three hole pattern on the
snowboard. With respect to the systems incorporating a hole
pattern, the holes on the board allow the snowboarder to adjust the
position of their bindings with respect to the board. The holes are
formed in the board to secure the binding to the board, using a
riding plate. Fasteners typically extend through the binding and
riding plate and into the board at the holes. Typically, three or
four holes are used to secure the binding to the board. However, in
both the three and 4 hole pattern systems, there are a very limited
number of positions to which the snowboarder can adjust his
bindings. The placement of the holes varies on each board. Each
pattern provides only about 4 different positions or settings at
most for stance adjustment of each binding. Alternatively, at least
some snowboards include a slider positioning system which simply
uses friction to prohibit sliding. In these snowboards, a binding
system also connects the rider to the board.
[0010] With each securement and hole pattern method, the user must
first remove the boot from the binding and then loosen and remove
the series of screws, typically with a screwdriver, so the binding
can be positioned at the desired location and angle. The screws
must be retightened to lock the binding in place and the user can
then reinsert the boot into the binding. Such an operation is
difficult, time consuming, and inconvenient for the snowboarder. It
is impractical to require a snowboarder to perform such a field
operation on their snowboard. This is particularly true given the
high cost of ski-lift tickets and the overall desire by riders to
maximize the number of runs performed during any given day.
[0011] Similarly, when snowboarders desire to adjust their stance,
the snowboarder needs to loosen and remove the series of screws,
and then numerically measure the distance, typically with a tape
measure, before the screws are retightened to lock the binding in
place. This process can be cumbersome, requiring the snowboarders
to carry screwdrivers and tape measures while snowboarding.
[0012] In addition, Forum snowboards has previously incorporated a
slider system into a number of their designs. FIG. 1 shows a
cross-sectional view of Forum's previous slider system design. The
slider system includes a plurality of interengaging surfaces. Two
of the surfaces are formed at an angle, which is generally about a
45-50.degree. angle. The surfaces form a plurality of teeth, which
are about 0.5 mm apart and about 0.15 mm deep. In this system, the
pressure created by clamping the binding to the slider system and
board locks the binding into place. By releasing the retaining
elements, the binding is free to be adjusted simply by moving the
binding.
[0013] Accordingly, a snowboard having an improved positioning
system and position adjustment system is needed.
SUMMARY OF THE INVENTION
[0014] The present invention comprises a gliding board, preferably
a snowboard. The board preferably includes a rider adjustable
fastener. The fastener comprises a channel having a plurality of
equally spaced apart surfaces. A fastening element is also
provided, having a plurality of equally spaced apart surfaces. The
surfaces of the fastening element engage with the surfaces of the

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0048] The following detailed description presents various specific
embodiments of the present invention. However, the present
invention can be embodied in a multitude of different forms as
defined and covered by the claims. In this description, reference
is made to the drawings wherein like parts are designated with like
numerals throughout.
[0049] Snowboard
[0050] With reference to FIGS. 2-5, the present invention comprises
a riding apparatus 100, which preferably comprises a snowboard. The
riding apparatus may include aquatic devices such as water skis, or
wakeboards, or snow riding devices, such as snow skis.
Alternatively, the riding apparatus 100 may include a sailboard,
wind surfing board, or kite surfing board. In general, the riding
apparatus of the present invention may comprise any ridable device
which requires one or more of the rider's limbs to be bound to the
device while it is being used.
[0051] In the embodiment shown in FIGS. 2-5, the riding apparatus
100 comprises a snowboard. In a preferred embodiment, such a
snowboard is an elongate structure, approximately 5 feet in length,
having an elongate body 102 with a front end 104 and a rear end
106. The board typically curves up at each end 104, 106.
[0052] The riding apparatus is preferably constructed from a
central core 110, as shown in FIG. 5. Surrounding this core is a
shell 112, which preferably comprises a sturdy and durable material
such as molded polyethylene or fiberglass. This material may also
comprise a composite material. The board also comprises a base 114.
The board may also include a plastic such as ABS to form the side
wall 116 of the board. The board may also include a metal edge 118
around at least a portion of the board. The material forming the
base 114 of the riding apparatus allows the board to glide along
the surface, which may include snow or water. The materials should
also be sufficiently lightweight to allow the board to be manually
transportable by the rider to the area of use.
[0053] The riding apparatus 100 preferably is characterized by a
flat or slightly concave rider support surface 120, which
preferably is of sufficient size to permit a rider to stand on the
rider support surface 120 with both feet.
[0054] In order to permit attachment to the riding apparatus 100 of
other components of the present invention, the shell 112 preferably
is capable of retaining one or more fasteners, to be described
hereafter.
[0055] The rider support surface 120 preferably is further
characterized by an elongate first channel section 122 and second
channel section 124 formed therein, which further extend into the
core 110. The channel sections 122, 124 preferably comprise a
linear recess which extends parallel to the longitudinal axis of
the riding apparatus 100. The upper opening 126 of the channel
sections 122, 124 preferably is sized to receive a fastener, to be
described hereafter.
[0056] The riding apparatus 100 of the present invention further
comprises a first riding plate 132, which preferably comprises a
flat disc sufficiently sized to receive a binding. The first riding
plate 132 preferably is constructed from a durable and lightweight
material such as plastic or aluminum.
[0057] The first riding plate 132 is adapted to receive a binding
133. The binding 133 is sized to receive and retain a single foot
of the rider. When the rider's foot is positioned within the
binding 133, the binding 133 engages the upper portion and sides of
the foot, and holds the foot against the first riding plate
132.
[0058] The first riding plate 132 further comprises a plurality of
slots 134, preferably four, slots corresponding with the channel
sections 122, 124. At least two and preferably four fasteners 136,
such as thumbscrews are supported by the first riding plate 132.
Each fastener 136 extends through a corresponding slot 134 formed
in the first riding plate 132, and projects within the first or
second channel sections 122, 124. Each fastener preferably is
releasably engaged within one of the channel sections 122, 124, as
will be described hereinafter.
[0059] When each fastener 136 is tightly engaged, the first riding
plate 132 is attached to the board. If it is desired to reposition
the first riding plate 132 longitudinally on the rider support
surface, the fasteners 136 are loosened sufficiently to permit the
first riding plate 132 to move with respect to the riding surface
120. The first riding plate 132 then is moved longitudinally above
the channel sections 122, 124 to the desired position on the rider
support surface 120. As the first riding plate 132 moves above the
first channel section, the fasteners 136 move along the same
direction while continuing to project within the channel sections
122, 124. Once the first riding plate 132 is repositioned, the
fasteners 136 are retightened, thereby immobilizing the first
riding plate 132 in its new longitudinal position on the first
rider support surface 120.
[0060] If it is desired to angularly reposition the binding 133
with respect to the rider support surface 120, the fasteners are
loosened sufficiently to permit angular movement of the binding
133. The binding 133 is then moved angularly, and preferably
rotated, with respect to the riding plate 132 to the desired
position. Once the binding 133 is repositioned, the fasteners 136
are retightened, thereby immobilizing the binding 133 in its new
angular position on the riding plate 132. An exemplary riding plate
is described in U.S. Pat. No. 5,967,542 to Williams et al., the
disclosure of which is hereby incorporated by reference.
[0061] The present invention preferably further comprises a third
and fourth channel section 142, 144, of identical construction to
the first and second channel sections 122, 124, formed in the rider
support surface 120. The channel sections 142, 144 preferably
comprise a linear recess 146 which extends parallel to the channel
sections 122, 123. More preferably, the third channel section 142
and the first channel section 122 are collinear, and the fourth
channel section 144 and the second channel section 124 are
collinear.
[0062] The riding apparatus 100 of the present invention further
comprises a second riding plate 152, which is identical in
construction to the first riding plate 132. Formed in the periphery
of the second riding plate 152 are a plurality of openings,
preferably four, each of which preferably comprises an elongate
slot 154. The slots 154 are positioned within the second riding
plate 152 at the corresponding positions occupied by the slots 134
in the first riding plate 132.
[0063] The riding apparatus 100 of the present invention further
comprises a second binding 153 which functions to attach the other
one of the rider's limbs to the second riding plate 152. The second
binding 153 is identical in construction and function to the first
binding 133. The second binding 153 is sized to receive and retain
a single foot of the rider, and preferably the foot of the rider
which is not received within the first binding supported by the
first riding plate 132. The second binding 153 preferably is
secured to the second riding plate 152 in the same manner as the
first binding 133 is attached to the first riding plate 132. If the
first binding 133 is shaped to fit a limb on one side of the
binding, such as a left foot, then the second binding 153 should be
sized to fit the corresponding limb on the opposite side of the
binding, such as a right foot.
[0064] At least two fasteners 156, such as screws are supported by
the second riding plate 152 in the same manner as previously
discussed with reference to the first riding plate 132. Each
fastener 156 is releasably engaged with the channel sections 142,
144. Each fastener 156 is constructed in the manner previously
discussed with respect to fasteners 136 associated with the first
riding plate 132. The second riding plate 152 is positionable
longitudinally and angularly within the third and fourth channel
sections 142, 144 and with respect to the rider support surface 120
in the same manner as discussed with reference to the first riding
plate 132.
[0065] In preparation for the use of the riding apparatus 100, the
longitudinal and angular positions of the first riding plate 132
and the second riding plate 152 are determined and fixed as
described above. The rider then inserts one foot into the first
binding and the other foot into the second binding. The riding
apparatus 100 then is used by the rider in its normal mode of
operation. If the rider desires to reposition the first and second
bindings, as required to accommodate a different rider or a
different stance of the same rider, the rider repositions the first
and second bindings, by adjusting the riding plates 132, 152, as
described previously.
[0066] From the foregoing, it will be appreciated that the riding
apparatus 100 of the present invention offers considerable
flexibility in the placement of the bindings, thereby permitting a
single riding apparatus 100 to be used by a variety of riders
having different limb spans, and further accommodating a wide range
of riding distances. Furthermore, the flexibility of placement of
the riding plates permits the rider to adjust stance width for
different snowboarding activities, as previously discussed. The
releasable nature of each riding plate with respect to the riding
surface permits replacement of the riding plates when they become
lost or damaged, or when a different size or style of plate is
required. This feature permits the riding apparatus 100 to be used
by a wide range of riders, while extending the useful life of the
apparatus.
[0067] I-Lock System
[0068] The mounting system will now be described in more detail.
The mounting system comprises a channel positioning system 400
which includes a channel element 402, a channel base 404, and an
insert 406. The components are assembled together to form the
positioning system 400, as shown in FIG. 6a. With reference back to
FIG. 5, the channel positioning system 400 is shown within the
board. The core 110 is preferably routed, prior to assembly, to
form slots within the core 110. The channels are sized and shaped
such that the channel positioning system 400 sits within the
channel. The channel element 402 and channel base 404 are assembled
together, as shown in FIG. 6a without the insert 406, and then
placed into the core 110 prior to final construction of the board.
The entire board is then assembled with the channel element 402 and
channel base 404 in place. In a preferred embodiment, a resin, or
similar adhesive, may surround the channel positioning system 400
prior to placement in the core 110. In an alternative preferred
embodiment, a dry fiberglass cloth may surround the channels for
improved retention. After the board is assembled and treated, slots
are cut through shell 112, reinforcement (if applicable), and
channel element 402 to form channels 122, 124, 142, 144 (FIG. 3).
The inserts 406 (FIG. 6a) and plugs are preferably added after the
board has been assembled.
[0069] With reference to FIGS. 7-12, the channel element 402 will
now be described in further detail. The channel element 402 is
shown in FIGS. 7-12 prior to assembly. The channel element 402 has
a generally elliptical shape as viewed in FIG. 7. The channel
element has an outer side 410 which faces the rider support surface
when assembled (FIG. 8). The channel element 402 also has an inner
side 412 which faces the other components of the positioning system
400, when assembled. The channel element has an elongate section
414 and two semi-circular ends 416, 418 at either end of the
elongate section 414. The channel is also shown with a protrusion
420 centrally extending down the length of the elongate section 414
and into the ends 416, 418 on the inner side 412. In an alternative
embodiment, protrusion 420 does not extend down the entire length
of the elongate section 414, but a portion of the length. After
assembly, at least a portion of the protrusion 420 is cut away to
permit the insert to slide within the channel created when the
protrusion 420 is cut away (See FIG. 6). The protrusion 420 serves
as a support which keeps the channel element 402 and channel base
404 parallel during assembly, as will be described hereinafter. In
an alternative embodiment, the channel element may be formed
without the protrusion 420.
[0070] The channel element 402 also includes a groove 422 around
the entire circumference of the inner side 412. The groove is
adapted to receive a complementary projection of the channel base,
which will be described in further detail hereinafter. The groove
422 is shown having a "P" shape, as shown in FIG. 9. The groove
starts out narrow at the inner surface, and has a width of about 1
mm, in a preferred embodiment. The groove then expands to have a
width of about 1.5 mm at it's largest dimension, in a preferred
embodiment.
[0071] A plurality of teeth 430 are equidistantly formed along the
length of the channel 402 in the longitudinal direction on the
inner side 412, as shown in FIGS. 10-11. The teeth are located on
either side of protrusion 420. It is also envisioned that the
channel element could be constructed without the protrusion. In
this case, the teeth 430 may extend across the entire width of the
inner side 412. The teeth comprise a plurality of surfaces, 432,
434, 436, 438 (FIG. 11). Surfaces 432, 436 are parallel to the
rider support surface 120. The surfaces 434, 438 are at an angle of
about 60-90 degrees, preferably about 65 degrees with respect to an
axis running longitudinally through the rider support surface 120.
The teeth are preferably equally spaced apart at increments of at
least about 1 mm. The teeth are at least about 0.2 mm deep,
preferably greater than about 0.5 mm deep. The tooth depth is a
projection of the clamping surfaces in the direction normal to the
plane of the board 100. This dimension is shown as "a" in FIG. 6b.
In this embodiment, the resistance created by the shape and size of
the teeth 430 prevents the insert 406 from sliding with respect to
the channel element 402.
[0072] In a particularly preferred embodiment, the channel element
402 is about 10-12 cm in length. The channel may extend anywhere
from 5-40 cm in length, depending on the particular board size and
rider preferences. However, the channel element 402 may also extend
along the entire length of the board as one continuous channel.
[0073] FIG. 12 shows the routing slot 440 which is formed,
preferably by machining, after assembly, by cutting out the
protrusion 420. The slot 440 should be wide enough such that the
retaining elements of the insert 406 can fit through the slot. The
slot 440 may be any shape which permits the longitudinal sliding of
the insert 406 with respect to the channel element 402. The slot is
preferably formed after the board 100 has been assembled including
the channel element 402 and channel base 404 assembly.
[0074] With reference to FIGS. 13-15, the channel base 404 is
shown. The channel base has the same shape and size as the channel
element 402. The channel base 404 has a generally elliptical shape
as viewed in FIG. 13. The channel base 404 has an outer side 510
which faces the board base 114 when assembled. The channel base 404
also has an inner side 512 which faces the other components of the
positioning system 400, when assembled. The channel base has an
elongate section 514 and two semi-circular ends 516, 518 at either
end of the elongate section 514.
[0075] The channel base 404 also includes a projection 522 around
the entire circumference of the inner side 512, which is adapted to
be inserted into the complementary groove 422 in the channel
element 402 to lock the channel element 402 and base 404 together.
In an alternative embodiment, the complementary groove 422 and
projection 522 do not extend along the entire circumference of the
channel element 402 and base 404, respectively, but over a portion
of the channel element 402 and base 404. Alternatively, the channel
element 402 may comprise the projection, and the channel base 404
may comprise the groove. Other means of attachment are also
contemplated herein in accordance with the present invention.
[0076] With reference to FIGS. 16-22, the insert 406 is shown. The
insert 406 has a generally "I" shape as viewed in FIGS. 16 and 18.
The insert 406 has a bottom side 610 which faces the inner side 512
of the channel base 404 when assembled. The insert 406 also has a
top side 612 which faces the inner side 412 of the channel element
402, when assembled. The insert has an elongate section 614 and two
round elements 616, 618 at either end of the elongate section
614.
[0077] The round elements 616, 618 are mirror images of one
another. The round elements may be a circular, oval, or elliptical
shape, depending on the particular embodiment. The round elements
616, 618 are designed to slide and engage with the inner side 412
of channel element 402.
[0078] A plurality of teeth 630 are equidistantly formed around the
periphery of the elements 616, 618 in the longitudinal direction on
the top side 612. The teeth are located on either side of elongate
section 614. The teeth 630 are arranged in a parallel manner. It is
also envisioned that the insert 406 could be constructed with the
teeth 630 extending across the entire width of the inner side 612
of the round elements 616, 618. The teeth comprise a plurality of
surfaces, 632, 634, 636, 638. Surfaces 632, 636 are parallel to the
rider support surface 120. The surfaces 634, 638 are at an angle of
about 60-90 degrees, preferably about 65 degrees with respect to an
axis running longitudinally through the rider support surface 120.
The teeth are preferably equally spaced apart at increments of at
least about 1 mm. The teeth are at least about 0.2 mm deep,
preferably greater than about 0.5 mm deep. The tooth depth is a
projection of the clamping surfaces in the direction normal to the
plane of the board 100. This dimension is shown as "a" in FIG.
6b.
[0079] The teeth 630 are designed to be complementary to teeth 430
of channel element 402. The teeth 430, 630 interlock with one
another upon assembly. In this embodiment, the resistance created
by the shape and size of the teeth 630 prevents the insert 406 from
sliding with respect to the channel element 402. FIG. 6b shows the
engagement of the teeth 630, 430. Surface 432 engages with surface
636, and surface 434 engages with surface 634, and so on. At least
one tooth 630 is engaged with a tooth 430, but preferably a
plurality of teeth 630 are engaged with a plurality of teeth 430.
In a preferred embodiment about 30 teeth 630 (15 teeth from element
616, 15 teeth from element 618) are engaged with the teeth 430 of
channel element 402. The teeth 430, 630 are shown as being
trapezoidal in shape; however, it will be appreciated that other
shapes may be used. It will also be appreciated that although the
teeth are shown as being spaced apart such that surfaces 432, 436,
632, and 636 are equal in length, surfaces 432 and 632 may be
greater in length than surfaces 436 and 636. As such, teeth 430 and
630 are equally spaced apart; however the incremental distance
between the teeth is greater than the width of the teeth.
[0080] As such, the angle of the surfaces 436, 438, 636, 638 and
the additional surfaces 432, 436, 632, 636 provide additional
strength and interengagement between the insert 406 and the channel
element 402. This reduces the chances of slipping associated with
the slider system of the prior art. As such, the clamping force
applied by the fastening of the riding plate 132 to the board via
the insert 406, plays a reduced or no role at all in preventing
sliding of the insert 406 along the channel element 402.
[0081] The insert 406 also includes at least one, but preferably
two retaining elements 660, 662. The retaining elements 660, 662
are formed in the elongate section 614, at the round elements 616,
618. The retaining elements are adapted to receive the fasteners
136, 156 of riding plates 132, 152. The retaining elements are
preferably threaded internally to receive the fasteners 136, 156,
which generally have complementary external threading.
[0082] As shown in FIG. 22, a V-notch may additionally be provided
in elongate section 614 to provide stress relief.
[0083] In a particularly preferred embodiment, the insert 406 is
about 5-6 cm in length. The channel may extend anywhere from 1-10
cm in length, depending on the particular board size and rider
preferences. The round ends are preferably about 2 cm in length and
about 1.5-2 cm wide. In a preferred embodiment, the length from
retaining element 660 to retaining element 662 is about 4 cm.
[0084] The channel element 402, channel base 404, and insert 406
are preferably made with a polyamide plastic. Alternatively, other
plastics having adequate strength and flexibility may be used. The
plastic may also be reinforced with glass fibers or other composite
materials. The materials used should provide adequate strength, but
also flex with the board to maintain an even flexibility for the
rider.
[0085] In a preferred embodiment, the channels 122, 124, 142, 144
are reinforced with a carbon fiber plate and Duren plate. This
reduces the risk of the insert pulling out of the channel system by
spreading the load over a wider area. It will be appreciated that
other materials, such as glasses, hard plastics, composites or
Kevlar may be used as reinforcement. Alternatively, the system may
be reinforced with aluminum, titanium, or other similar metals or
alloys. The reinforcement is preferably located at or near the
channel system 400. However, the reinforcement may extend over the
entire board.
[0086] As previously described with reference to FIG. 6, channel
element 402, channel base 404, and insert 406 are assembled
together to form a locking adjusting system 400. It will be
appreciated that the locking adjusting system provides a large
range of adjustability with respect to the prior art designs
involving hole patterns. The system 400 also provides increased
strength with respect to the slider systems of the prior art.
[0087] Channel base 404 is aligned with channel element 402, such
that projection 522 corresponds with complementary groove 422. The
components are press-fit together such that projection 522 seats
within groove 422. The channel element 402 and channel base 404
assemblies are arranged and aligned in the core 110, such that
channels 122, 142 are parallel to channels 124, 144, respectively,
and channels 122, 124 are colinear to channels 142, 144,
respectively. Reinforcement, such as a carbon fiber plate and/or
Duren plate, or other similar materials, as previously described,
is preferably placed over the core 110 prior to the shell 112. The
board is then assembled according to general board-making
procedures, as known to those of skill in the art.
[0088] After the board has been assembled with the channel base 404
and 402 in place in the board, the protrusion 420 is cut out of the
channel element 402 by forming routing slot 440. The insert 406 is
then oriented within the channel element 402 and channel base 404
assembly, such that elongate section 414 and elongate section 614
are parallel, and teeth 430 engage teeth 630.
[0089] The insert 406 may be adjusted longitudinally with respect
to the channel element 402. The teeth 630 of insert 406 interlock
with the teeth 430 of channel element 402, such that in a closed
position, the insert 406 cannot slide or be adjusted with respect
to channel element 402. However, in an open position, it is
possible to adjust the insert 406 incrementally with respect to
channel element 402. In a preferred embodiment, the incremental
distance that the insert 406 can be adjusted with respect to the
channel element 402 is about at least 1 mm. In the preferred
embodiment, it the incremental distance is about 1 mm. As such, the
teeth are large enough that the system is not weak and slippage is
reduced. Furthermore, the teeth are small enough that the rider is
able to still adjust the location of the binding to a large number
of positions.
[0090] By releasing the engagement state, it is possible to
longitudinally move the binding 133, 153 with respect to the rider
support surface 120 by adjusting the position of insert 406 in
channel sections 122, 124, 142, 144. By tightening the fasteners
into retaining elements 660, 662, a downwardly directed force is
created on the insert, engaging and locking the insert within the
channel at a particular location, which determines the stance
width.
[0091] With reference to FIGS. 23-24, the new positioning system
was tested against Forum's previous slider system, which was
discussed in more detail in the Background. The clamping force,
provided by fastening the binding into the board, provided the
interengagement between the binding and the slider system, in the
previous slider system. However, the present invention uses the
teeth to provide the interengagement between the insert 406 and
channel 402. It was found with the new interlocking teeth, the
strength of the system increases nearly 3-fold. Although there is
less adjustability with the new shape and size of the teeth, the
grip provided by the improved shape greatly increases the strength
of the system.
[0092] Locating System
[0093] With reference to FIGS. 25-28, the locating system 700 of
the present invention is shown. The locating system 700 preferably
comprises a plurality of indicia 702, as shown in FIG. 26. Indicia
702 are provided on the rider support surface 120 and comprise
length increments equally spaced apart. Indicia 702 are evenly
spaced on a linear scale so that measurements of units of distance
may be taken with reference thereto. The numbers and notches are
spaced apart at incremental distances. In a preferred embodiment,
the indicia 702 are spaced at about 1 mm increments. Preferably,
the indicia 702 are spaced apart an even multiple of the spacing of
the teeth 430, 630.
[0094] The locating system 700 also preferably comprises a
plurality of evenly spaced apart grooves or notches 704 associated
with the indicia 702 to facilitate easy stance width adjustment.
Alternatively, the locating system 700 comprises a label which
attaches to the board comprising lines corresponding to the notches
704 and indicia 702 corresponding to the lines. In a preferred
embodiment, the notches 704 are evenly spaced at about at least 1
mm increments. Preferably, the notches 704 are spaced apart an even
multiple of the spacing of the teeth 430, 630.
[0095] The indicia 702 preferably comprise numbers or a symbol,
which correspond to notches 704. The numbers or symbols are a
measurement representative of stance width.
[0096] The notches 704 may not all include a corresponding indicia
702. For example, every other or, alternatively, every fifth, or
similar increments of notches 704, may have an indicia 702
associated therewith. Although, the notches 704 are shown as being
spaced apart in units of mm, it will be appreciated that cm or
inches, or any other suitable measurement of length may be used in
accordance with the present invention. Similarly, the indicia 702
may be in units of mm, cm, inches, or a combination thereof.
[0097] The locating system 700 also preferably comprises a
reference point 710. The reference point 710 preferably corresponds
to a stance width associated with the particular board in use. The
reference point may be indicated by highlighting an indicia 702
associated with the reference point 710. Alternatively, the notch
704 associated with the reference point 710 may be longer, deeper,
or highlighted. In a preferred embodiment, the stance width of a
rider is measured from a first reference point associated with a
first set of channels 122, 124 to a second reference point
associated with a second set of channels 142, 144, such that the
longitudinal distance from the first reference point 710 to the
second reference point 710' is a measure of stance width. The
distance between the reference points 710, 710' varies from board
to board, but the distance is preferably about 18-22 inches (about
46-56 cm)
[0098] Preferably, the indicia 702 and notches 704 are arranged to
provide ease of readability for the rider. Accordingly, some of the
notches may be longer than others to ease readability.
Alternatively, particular notches 704 or indicia 702 may be
highlighted. In accordance with an alternative embodiment,
different colors or color schemes may be used to increase the ease
of use.
[0099] In a preferred embodiment, the locating system 700 is in the
form of a label. The label is preferably a material having adhesive
on one side. Alternatively, the material is adapted such that an
adhesive may be applied to one side of the label or to the board so
that the label may be adequately secured to the board. The label
may alternatively be a plastic or metallic material, which may be
fastened to the board, such as by drilling screws into the board
through the label.
[0100] In an alternative embodiment, the indicia 702 and notches
704 are applied to the board by etching the indicia 702 and notches
704 at a depth of about 1 mm.
[0101] In a preferred embodiment, the locating system 700 is
provided next to the adjusting system 400, as previously described
herein. However, it also envisioned that locating system 700 may be
provided on the rider support surface 120 of a board having a hole
pattern system of the prior art, as previously described herein in
the background of the invention.
[0102] In the embodiment wherein the locating system 700 is
associated with the adjusting system 400, the stance width is
measured from the center of the first and second channels 122, 124
to the center of the third and fourth channels 142, 144. The stance
width can then be adjusted by adding or subtracting the
corresponding distances associated with each notch 704 and/or
indicia 702 to determine the correct stance width.
[0103] In operation, reference point 710 corresponding to the
recommended stance width of the particular board in use is provided
on the board. The rider mounts the board initially positions
himself at the reference point 710. If the rider desires to adjust
the stance width, the rider measures forward or backward from the
reference point 710 by using the indicia 702 located on the
locating system 700 to find the ideal stance width for the
particular conditions and rider using the board.
[0104] Combined System
[0105] In a preferred embodiment, the adjusting system 400 and
locating system 700 are combined to form a locking mounting system
800, as shown in FIGS. 27-28. The teeth from the positioning system
and the numbers from the numbering system are calibrated together,
so that an exact position can be obtained.
[0106] Channel element 402, channel base 404, and insert 406 are
assembled together to form a locking adjusting system 400. It will
be appreciated that the locking adjusting system provides a large
range of adjustability with respect to the prior art designs
involving hole patterns. The system 400 also provides increased
strength with respect to the slider systems of the prior art.
[0107] The locking adjusting system 400 permits the rider to
longitudinally adjust the position of the riding plate 132 with
respect to the rider surface 120. The teeth 630 of insert 406
interlock with the teeth 430 of channel element 402, such that in a
closed position, the insert 406 cannot slide or be adjusted with
respect channel element 402. However, in an open position, it is
possible to adjust the insert 406 incrementally with respect to
channel element 402. In a preferred embodiment, the incremental
distance that the insert 406 can be adjusted with respect to the
channel element 402 is about at least 1 mm.
[0108] The locating system 700 preferably comprises a plurality of
indicia 702 on the rider support surface 120. The indicia 702
comprise a plurality of length measurements equally spaced apart.
The indicia may comprise a plurality of numbers or other symbols,
which could be used to represent different stance width
measurements. The locating system 700 also preferably comprises a
reference point 710 associated with an ideal stance width,
associated with each board.
[0109] A central mark, associated with an ideal stance width, is
associated with each board. This mark is known to the board
manufacturer, and varies for different lengths and styles of board.
In the combined system, the central mark associated with the board,
and preferably associated with a central point of the channel
adjusting system 400, is provided. The locating system 700 can be
designed such that a reference point associated with the central
mark is also provided. The central mark and the reference point can
be aligned such that the location system permits the rider to
adjust the channel adjusting system to a desired location. The
locating system is preferably provided on the rider support surface
120 between the channel sections 122, 124, and 142, 144.
[0110] The adjusting system 400 is preferably provided with the
manufactured board, as previously discussed. The location system
700 is preferably applied to or formed on the board after the
adjusting system 400 is in place, by any of the methods previously
described.
[0111] The notches 704 preferably correspond with the teeth 430,
630 associated with the adjusting system 400. As such, the teeth
430, 630 and notches 704 are equally spaced apart in at least about
1 mm increments.
[0112] The location system 700 serves as a reference mark so that
the rider can find their favorite stance or a specific stance.
[0113] Although the present invention has been described in terms
of certain preferred embodiments, other embodiments of the
invention including variations in dimensions, configuration and
materials will be apparent to those of skill in the art in view of
the disclosure herein. In addition, all features discussed in
connection with any one embodiment herein can be readily adapted
for use in other embodiments herein. The use of different terms or
reference numerals for similar features in different embodiments
does not imply differences other than those which may be expressly
set forth. Accordingly, the present invention is intended to be
described solely by reference to the appended claims, and not
limited to the preferred embodiments disclosed herein.
