Description
CROSS-REFERENCE TO RELATED APPLICATION
[0001] This application is a continuation-in-part of U.S. patent
application Ser. No. 09/105,974, filed Jun. 26, 1998, which
application is a continuation of U.S. patent application Ser. No.
08/538,754, filed Oct. 2, 1995.
FIELD OF THE INVENTION
[0002] This invention is related to shock absorbing devices for
snowboards, specifically to such devices which mitigate uneven
terrain, while enhancing the performance of the snowboard.
BACKGROUND AND SUMMARY OF THE INVENTION
[0003] Snowboarding has evolved from a fledgling sport in the 70's
to a huge recreational and commercial enterprise in the 90's. There
have been many recent advances in board and binding technology, but
only one which specifically addressed the issue of shock
absorption. This is simply a high-density foam pad which is mounted
under the boarder's boot. Because this concept has been used in
many other similar applications, it isn't patented. Quite frankly,
it isn't effective either.
[0004] Although snowboarding is similar to snow skiing in many
ways, there are some salient differences. Most notably, the
boarder's legs are fixed in a transverse position on a single
board, which precludes any independent movement of the legs. The
boarder executes turns by angling the knees in concert with
rotation and angling of the torso. As such, one can turn as quickly
as on skiis, and, surprisingly, go just about as fast. Although the
feel of charging down a slope is somewhat akin to surfing a large
wave, one does not have the convenience of simply falling off the
board should a fall be in the making. Instead, the attached board
can become a veritable torsion bar on the body, which has resulted
in a spate of injuries unique to snowboarders.
[0005] One of the primary causes of falls and snowboard-specific
injuries is bumps, and how the boarder negotiates them. Unlike in
skiing, where the legs are independent, the boarder's legs are in a
fixed position, which reduces their available "travel", or ability
to absorb the shock of a bump. Tearing of the collateral ligaments
in the knee can result from pitching forward due to this decreased
absorptive capacity. A prime example of the need for additional
shock absorption is apparent when snowboarding in fresh snow over a
hard sub-layer. In this situation, the whole body is constantly
receiving unpredictable jolts. Thus, in the interest of preventing
injuries, and adding a new dynamic to the "feel" of the board, I
submit the following designs.
[0006] Since similar designs as those described for snowboards may
be used for skiis and in-line skates, I have also covered these
possibilities in this application. However, in the interest of
simplicity, unless otherwise specified, all designs will be
referred to as snowboard suspension systems.
[0007] Accordingly, several objects and advantages of the present
invention are:
[0008] (a) to provide a simple means for absorbing shocks from
bumpy terrain, while allowing for optimal edge control.
[0009] (b) to create an entirely new dynamic for the snowboarder--a
more lively "feel", and enhanced turning capability.
[0010] (c) to provide a means for the boarder to move forward on
level terrain without undoing the bindings, by "bouncing" the board
back and forth--similar to what skateboarders do.
[0011] (d) to minimize the possibility of injury from rough
terrain--decrease the amount of wear and tear on the boarder's
body.
[0012] (e) to increase the possibilities in "freestyle" boarding,
due to the springier dynamic.
[0013] (f) to allow for a greater range of weight distribution and
fore-aft transference of weight during a turn.
[0014] (g) to make the sport more appealing to older people, whose
bodies aren't as resilient as they once were.
[0015] Still further objects and advantages will become apparent
from a consideration of the ensuing description and drawings.
[0016] In summary, the invention is a snowboard suspension system
for use with a snowboard that includes an elongate, flexible
snow-planing member, dual elongate bindings for receiving a user's
boots, and where the long axis of the bindings are located at an
angle relative to the long axis of the snow-planing member. The
snowboard suspension system of the invention includes dual
suspension elements, each being coupled to a corresponding one of
the dual bindings, and each suspension element having a top
surface, a bottom surface and a desired thickness, and being formed
to compress a preselected amount when a suitable force is applied
to either the top or bottom surface. The invention also includes
joining means for coupling each suspension element to the
snow-planing member so that both suspension elements are linked by
the snowboard.
[0017] The dual suspension elements may also each include a binding
member with a long axis and securing means for attaching to a
corresponding binding. The joining means may take the form of dual
mounting members each with corresponding long axes and securing
means for attaching to the snow-planing member so that the long
axis of each mounting plate is at an angle relative to the long
axis of the snow-planing member.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0059] FIG. 1 shows an isometric of the preferred embodiment of the
snowboard suspension system of the invention at 10. Also shown are
portions of a snowboarder's legs and feet A, the snowboarder's
boots B, associated boot bindings C, and a snowboard D. Any
conventional boots, bindings and snowboards are usable with the
invention. Snowboard D may be thought of as an elongate, flexible
snow-planing member, and dual elongate bindings C are for receiving
boots B. Corresponding long axes E of the bindings are located at
angles F relative to a long axis G of the snowboard. System 10
includes fastener structure that preferably takes the form of dual
suspension elements 10a and 10b, each being coupled to a
corresponding one of the dual bindings C.
[0060] Referring to FIGS. 2-3, the illustration of suspension
element 10a is meant to be representative of both elements 10a-10b,
where each element includes a top region or plate 12, a bottom
region or plate 14 and a desired thickness T (preferably between
about 1- to 1.5-inches), and being formed to compress a preselected
amount when a suitable force is applied to either the top or bottom
plate. Also depicted is compressible section such as foam layer 16
and links such as bales 18. As shown in FIGS. 2-8, each bale is
angled or canted so that it is not at 90 degrees with respect to a
plane containing the snowboard. In FIG. 2, an angle H depicts of
less than 90 degrees, and preferably in the range of about 70-80
degrees, provides the proper bias toward compression that allows
system 10 to meet the above objectives. The dimensions of plate 12
may be about 9-inches in length by about 6-inches in width, and the
dimensions of plate 14 may be about 9-inches in length and about
6.75-inches in width. These dimensions have been found suitable for
conventional snowboards, but suitable changes in such dimensions
are possible.
[0061] Referring to FIG. 4, suspension element 10a also includes
first joining means or first joiners 20 for coupling each
suspension element 10a (and 10b, although undepicted in FIG. 4) to
snowboard D (as shown in FIG. 1) so that both suspension elements
are linked by the snowboard. First joiners 20 may also be thought
of as screws or screw-serts, and preferably take the form of 6
mm.times.16 mm stainless steel screws. For reasons that will be
described, either 3- or 4-screws are placed through appropriately
sized openings 22a (oblong-shaped in cross section), 22b
(approximately circular in cross section) in plate 12 and in plate
14.
[0062] Referring to FIGS. 3-4, suspension element 10a also includes
second joining means or second joiners 24 (again preferably
screws--two representative ones of the four are depicted) for
attaching to a corresponding binding C (see FIG. 3) by placing the
lead ends of the screws through suitable openings in the bindings
(see FIG. 3), and turning the screws into threaded fittings 26 (a
representative one of which is shown in FIG. 4) that are suitably
fastened within openings 28 formed in plate 12.
[0063] Still referring to FIGS. 3-4, the ends of each bale 18 are
placed through corresponding cylindrical sleeves such as sleeve 30
in each plate 12, 14, with each sleeve suitably fastened within
cylindrical bale openings, such as opening 32 formed in each plate
12, 14. The ends of each bale 18 are circumferentially notched to
allow placement of a washer 34 and lock washer 36 to hold each bale
in the desired position within each sleeve. If each plate is formed
by molding a suitable composite material, it has been found that
reinforcing the length of each cyclindrical opening that receives a
sleeve like sleeve 30 with angled, linear sections 38 will tend to
limit shrinkage and ensure proper location of bale openings in the
finished plate. Recesses 40 are preferably square in cross section
and allow access to the ends of the bales for placement/sliding
movement of washers 34 and lock washers 36. Recesses 42 are the
usual types of recesses when forming the plate from spheroidal
elastomers. Recesses 44 are provide a distinctive look to plate 12
and are ornamental.
[0064] Referring again to FIG. 4, a suitable adhesive layer 46 is
applied to the top surface of foam layer 16. It is possible to use
any suitable means to attach foam layer 16 to one or both plates
12, 14. Suitable openings 48 are formed in foam layer 16 to allow
screws and screwdrivers to pass therethrough to attach plate 14 to
snowboard D (see FIG. 13).
[0065] Referring to FIGS. 5-8 and 14-15, arrows are shown to
illustrate that system 10 will result in the same controlled,
horizontal, planar compression between plates 12 and 14 regardless
of whether the snowboarder puts toe pressure (FIG. 6), heel
pressure (FIG. 7), side (of boot or boots) pressure (FIG. 8), or
toe-and-heel pressure (FIG. 15) on the plates.
[0066] Referring to FIGS. 9-10, two alternate embodiments of the
suspension system of the invention are shown. In FIG. 9, suspension
element 110a is formed integrally by extruding suitable synthetic
materials to form links 118 integral with plates 112 and 114 that
sandwich a foam layer 116. Plate 114 is suitable attached to
snowboard D, and plate 112 is suitably attached to binding C as
shown and described above. In FIG. 10, plate 14 is replaced by dual
elongate panels 214 that are formed of a suitable material and
include openings for receiving and suitably holding corresponding
ends of bales 218. Bales 218 should be positioned at an angle H as
described in connection with FIG. 2.
[0067] FIGS. 11-12 show the reason for constructing plate 14 with
the 5-hole pattern of holes 22a and 22b. The result is to allow for
the 3-screw (FIG. 11) or 4-screw (FIG. 12) combinations which will
accommodate attachment to the two types of hole patterns that
snowboard manufacturers presently use when manufacturing
snowboards. By constructing plate 14 as shown, there is no need for
drilling additional holes in the snowboard when attaching
suspension elements 10a and 10b.
[0068] Referring to FIG. 13, one can see how plate 14 can be
attached to the snowboard by manually compressing plates 12 and 14.
The result is to align holes 22a and 22b in plates 12 and 14 (and
corresponding holes in foam layer 16) to allow screws and a
screwdriver to fit therethrough for tightening screws in the
desired holes.
[0069] FIG. 17 shows the most elemental version of the snowboard
suspension system. It is simply a piece of springy material bent to
form a mounting plate 327, and binding plate 329. The fulcrum is a
spring hinge 325. It may be fabricated from spring steel preferably
stainless), or some form of composite with fiber reinforcement. A
bottom stop 323 may be placed anywhere between the hinge and distal
end of the mounting plate 327. Another version incorporates a
regular hinge 326 as the fulcrum (as in FIG. 18), and a damper 330
may be included as a replacement for the spring hinge 325. All the
figures on sheet 7 deal with simple snowboard suspension systems,
as opposed to the compound snowboard suspension system shown in
FIGS. 22 and 23. In all cases, the snowboard suspension system is
mounted between the board and the boot/binding.
[0070] FIG. 19 demonstrates the placement of a hinge-type snowboard
suspension system with dampers and baffles. Any of the other
versions except for FIGS. 27 and 28 have similar placements.
[0071] The cant pictured in FIG. 20 can be made out of any water
and temperature-resistant high durometer (preferably over 80)
material. It may be a simple angle, or a compound angle, usually
between 4 and 15 degrees, depending on the preferences of the
boarder. All boot/binding 324 systems are mounted on the top of the
binding plate 329.
[0072] In the hinge-type snowboard suspension system with damper
pictured in FIG. 18, a damper connector 328 may be used to connect
the binding plate 329 with the damper 330 in any fashion which
maximizes vertical movement of the binding plate 329. The damper
330 can be a variety of things--air/oil shocks, rubber, elastomers,
springs, air bladders--any combination or anything which is
resilient and has rebound characteristics. Attachments of the
boot/binding 324 to the binding plate 329, or the mounting plate
327 to the board 322 are achieved through the standard
means--screws, slots, glues, or any other strong fastening systems.
Current systems for attaching bindings to snowboards are
adequate.
[0073] The compound spring-type snowboard suspension system
pictured in FIG. 22 is the same material as the snowboard
suspension system pictured in FIG. 17, but configured in an S
curve, so as to provide vertical compression to the side of each
angle. This increases the available travel and allows for a more
level binding plate 329.
[0074] In the compound hinge-type snowboard suspension system in
FIG. 23 the mounting plate 327 is articulated with the connection
plate 331 via a hinge 326. The connection plate 331 then
articulates with the binding plate 329 via another hinge 326. On
one side (in this case the left), there is a damper 330 between the
binding plate 329 and the connection plate 331. On the other side,
there is another damper between the connection plate 331 and the
mounting plate 327. These dampers are comprised of the same
materials as previously described. They may also be connected to
the plates (327, 329, 331) via damper connector 328 type pieces,
such that maximum vertical travel is facilitated. Placement of the
damper 330 so that a cantilevered configuration is achieved is also
possible.
[0075] In the scissor-type snowboard suspension system pictured in
FIG. 24, the mounting plate 327 is connected to two scissor alms
333 via hinges 326. They cross each other at another hinge 326, and
then connect to the binding plate 329 via two more hinges 326.
Horizontal movement of both ends of the scissor alms 333 is
accomplished through anything which allows the hinge free
horizontal movement, while limiting lateral and vertical play.
There are many possible permutations of this design too broad to
cover, thus the illustration and description are simplified.
[0076] The telescoping snowboard suspension system pictured in FIG.
25 incorporates two telescoping dampers 334 between the mounting
plate 327 and the binding plate 329. The attachment in both these
areas is very strong, to limit any lateral play (a must for edge
control), while allowing for vertical travel. Ideally, they should
be very similar to the front forks on a motorcycle--a damping
member which slides back and forth on a piston or plunger. As long
as the telescoping members are machined to close enough tolerances
(in the 0.008-0.014 range) the damping mechanism within each
telescoping damper 334, can be any of the aforementioned
materials--coil springs, elastomers, air/oil combination, or simply
air pressure.
[0077] In the parallelogram-type snowboard suspension system
pictured in FIG. 26, the mounting plate 327 articulates with the
slanted arms 335 via hinges 326. The hinges 326 also serve to
connect the binding plate 329 with the slanted arms 335. A damper
330 may be placed between the mounting plate 327 and the slanted
arms 335, or the binding plate 329 and the slanted arms 335.
Anything which allows for damping of the vertical movement of the
binding plate 329 is fine. The dampers 330 may be any of the
aforementioned materials.
[0078] In the cantilevered full-length snowboard suspension system
pictured in FIG. 27, both boot/bindings 324 are mounted on a single
binding plate 329. This articulates with the mounting plate 327 via
a broad hinge 326. A damper 330 can be placed anywhere between the
hinge and the mid-section of the binding plate 329 to maximize the
cantilevered effect. As an alternative, the damper may also be
placed towards, or beyond the end (and attached via a damper
connector 328) of the binding plate 329.
[0079] With the hinge-type suspension system with damper adapted to
fin in-line roller skates pictured in FIG. 28, there are several
special design considerations. As the hinge must be decreased in
width (to roughly the width of the wheels, compared to the width of
a snowboard), it isn't as inherently strong as with the snowboard,
and must therefore be of larger diameter. Also, the binding plate
329 and mounting plate 327 must be thicker in order to counter the
lateral thrust which is applied from the skater's stride. A
piston-type air/oil damper 330 is the best choice for shock
absorption and rebound. The shaft of the piston allows for
increased lateral control and stability. More spring and less
dampening are desirable qualities of the damper 330, as it's
important not to absorb, but enhance the lateral thrust from the
skater's stride. Top and bottom attachments of the damper 330 must
be of sufficient strength to minimize lateral play during the
stride.
Operation
[0080] The central concept of the various versions of the snowboard
suspension system is to allow for vertical travel of the
boot/binding 324, while limiting any horizontal movement or
rotation. This gives the boarder the advantage of having bumps
dampened, while still allowing for maximum edge control. All the
versions illustrated address this dynamic, with varying degrees of
shock absorption and damping.
[0081] In each of the designs illustrated on page one, the binding
plate 329 moves radially in relation to the hinge (325, 326),
decreasing the distance to the mounting plate 327, thus absorbing
shocks that would normally be felt by the boarder. A bottom stop
323 may be incorporated to prevent the binding plate 329 from
bottoming out on the mounting plate 327. Also, a baffle system made
of rubber or some other flexible material may be placed between the
binding plate 329 and the mounting plate 327 in order to prevent
the buildup of ice or snow.
[0082] The compound spring-type snowboard suspension system
pictured in FIG. 22 works similarly to the first two, but adds
another curve to allow for more travel.
[0083] All the snowboard suspension systems pictured in FIGS. 23-26
have the advantage of maximum travel coupled with relative constant
fore-aft angle despite compression of the binding plate 329. Of
these, the hinged compound snowboard suspension system with dampers
(pictured in FIG. 23) is the most simple, and is thus the preferred
embodiment. Any vertical forces are dampened by the angle of the
connection plate 331 becoming more acute from the dampers 330
compressing, thus allowing the binding plate 329 to move towards
the mounting plate 327.
[0084] The scissor-type snowboard suspension system pictured in
FIG. 24 allows for vertical travel of the binding plate 329 by
increasing the acute angle on the scissor arms 333. In the
telescoping-type snowboard suspension system pictured in FIG. 25,
the binding plate 329 moves in relation to the mounting plate 327
via telescoping dampers 334.
[0085] In the parallelogram-type snowboard suspension system
pictured in FIG. 26, there is a great possibility of vertical
travel as long as the damper(s) 330 are mounted outside of the
slanted arms 335, in order to provide clearance.
[0086] In the cantilevered full-length snowboard suspension system
pictured in FIG. 27, the binding plate 329 moves radially in
relation to the hinge 326, decreasing the distance to the mounting
plate 327. The cantilevered damper 330 allows for vertical travel.
The design approximates the "feel" of a standard board, due to both
bindings being mounted on the binding plate 329, instead of moving
independently. This is neither an advantage or disadvantage, simply
another choice for those who prefer it. In order for this to work
optimally, the mounting plate 327 must extend to the area below
where the rear bindings 324 are mounted. The mounting plate must
also be of a semi-flexible material, in order to allow for free
flexion of the board.
[0087] In each version the boot/binding 324 is always mounted on
the binding plate 329, and the snowboard suspension system is
secured to the snowboard 322 via the mounting plate 327. This
allows for after-market fitting of snowboard suspension systems, in
addition to fitting right from the factory. As previously
mentioned, either "soft" or "plate" bindings may be used.
[0088] Use of these snowboard suspension systems is very simple.
The boarder simply attaches the boot/bindings 324, and proceeds as
they would on a standard board without snowboard suspension system,
exuberant with the enhanced "feel" of the board.
[0089] The suspension system for in-line roller skates pictured in
FIG. 28 is well-suited for inclusion in production skates. However,
there are some possibilities for after-market products. Anything
which allows for a flex-free connection between the bottom of the
boot 324, and the binding plate 329 is fine. One possibility is to
offer a system wherein the hinge 330 and mounting plate 327 are an
integral unit, and can be changed on a given skateboot by removing
them at the hinge 330, and replacing them with a similar assembly
that offers different performance features.
Conclusion, Ramifications, and Scope of Invention
[0090] There are many possibilities for further elaborations of
these basic designs. In terms of materials usage, the most
desirable combinations would be those that offer lightweight and
strength. Any of the carbon fiber reinforced composites, or alloys
would fit the bill. Whatever material is used should be resistant
to temperature extremes, UV radiation, corrosion, chipping,
breaking, or other forms of breakdown. All fittings should be
stainless tell, or some other corrosion-resistant material. The
actual snowboard suspension system may be mounted with the fulcrum
or hinge 326 mounted towards the front or back. This is largely
dependent on fore-aft angular considerations of the broader. A
baffle 321 system may be incorporated in order to keep snow
entirely out of the area of compression. A variety of dampers 330
may be used, ranging from simple air bladders to sophisticated
air/oil shocks and torsion bars. A configuration which allows for
progressive damping by combining various dampers 330 is the most
desirable. The "feel" of the snowboard suspension system will be
determined by the relative springiness and travel of each
configuration. Every snowboard suspension system could be
custom-tailored to the individual boarder by adjusting vertical
travel, springiness, damping, sideways deflection, and placement of
the snowboard suspension system on the board. These factors would
be influenced by the boarder's skill, weight, interests (e.g.
freestyle or racing), and preferred terrain.
[0091] The hinged and hinged-compound type snowboard suspension
system (as in FIGS. 18 and 23) are the most flexible in terms of
allowing for the aforementioned customized configurations. As such,
they are the preferred embodiments. By adjusting the placement of
the dampers 330 relative to the hinges 326, first through third
class levers can be incorporated. In addition, by varying the
durometer of each damper 330, progressive rebound and damping can
be attained. Different durometer dampers 330 may be used on front
and back, depending on the conditions. A cantilever-style
configuration is the most desirable in terms of maximizing the
amount of travel in relation to compression of the damper 330. For
the current use, compression-type dampers 328 would be preferred
over elongation-type dampers. Any other design considerations would
be dictated by cost, available materials, and desired performance
features.
[0092] These types of suspension systems can also be adapted to fit
downhill skiis. The only real difference is a greater emphasis on
controlling fore-aft flexion, which has been done with the designs
pictured in FIGS. 23-26. Not only do these systems allow for
increased shock absorption, but, as with snowboards, they alter the
"feel" of the skin in rather interesting ways.
[0093] The hinge-type snowboard suspension system with damper
adapted to fit in-line skates (as pictured in FIG. 28) is a
significant improvement over current fixed systems insofar as it
dampens shocks and significantly enhances the feel of the skates
due to the rebound effect and energy return. Alterations may be in
the form of the other designs described herein. The fulcrum, or
hinge 326 may be placed further back, and a damper positioned in
front, as well as behind it. A lock-out mechanism could be
incorporated which keeps the suspension system from working, should
that be desirable. Various damper 330 combinations could be offered
for different weights and abilities.
[0094] Accordingly, the reader will see that the various designs
for a snowboard suspension system covered by this application have
the following advantages over current board/binding
configurations:
[0095] They provide a way to quickly customize the feel of the
board.
[0096] They minimize the possibility of injury from rough
terrain.
[0097] They provide a means for the boarder to move forward on
level terrain without undoing the bindings, by "bouncing" the board
back and forth--similar to what skateboarders do.
[0098] They create an entirely new dynamic for the snowboarder--a
more lively "feel," and enhanced turning capability.
[0099] They provide a simple and effective means of absorbing shock
from bumpy terrain for snow boarders, skiers, and skaters
alike.
[0100] They increase the possibilities in "freestyle" boarding, due
to the springier dynamic and adjustability.
[0101] They allow for a greater range of weight distribution and
transference of weight during a turn.
[0102] they make the sport more appealing to older people, whose
bodies aren't as resilient as they once were.
[0103] Although the description above contains many specificities,
these should not be construed as limiting the scope of this
invention, but as merely providing some illustrations of some of
the presently preferred embodiments of this invention. The basic
concept of a binding plate 329 which moves vertically in relation
to a mounting plate 327 and has a means for damping or enhancing
this movement is the central feature of these designs. To my
knowledge, there are no precedents in the prior art which these
designs emulate. Thus the scope of these designs should be
determined by the appended claims and their legal equivalents,
rather than by the examples given.
