Description
[0001] This application claims priority to and the benefit of U.S.
Provisional Application No. 61/052,038, filed on May 9, 2008, which
is incorporated in its entirety in this document by reference.
FIELD OF THE INVENTION
[0002] This invention relates generally to the field of exercise
equipment. In particular, the invention relates to a fitness paddle
that allows a user to simulate the action of paddling a canoe or
kayak, thereby providing both aerobic and anaerobic exercise.
BACKGROUND OF THE INVENTION
[0003] Watercraft paddling sports involve a person propelling a
watercraft through a body of water such as a river or lake with a
paddle. Two common watercraft paddling sports are canoeing and
kayaking. Canoes are small, narrow boats that are usually pointed
at both ends and open on top. Most canoeists use a paddle having a
single paddling blade on one end of a shaft, and a T-shaped handle
on the other end. In order to paddle a canoe, a canoeist sitting or
kneeling in a canoe typically places one hand on the shaft of the
paddle, and the other hand on the T-shaped handle. The blade is
then dipped into the water on the side of the canoe and pulled
backward, causing the canoe to move forward through the water.
[0004] Kayaks are also small narrow boats that are usually pointed
on both ends, and are usually closed on top. Kayaks are typically
propelled by a double-bladed paddle, i.e. a shaft having a blade on
both ends. In order to propel a kayak, a kayakist typically spaces
his or her hands along the shaft, and alternatively dips each blade
into the water on either side of the kayak.
SUMMARY OF THE INVENTION
[0005] According to various aspects, the present invention is a
fitness paddle exercise device for simulating the action of
paddling a canoe or a kayak. In one aspect, the device can comprise
an elongate rod having a longitudinal axis, a proximal end and an
opposed distal end. In another aspect, the device can further
comprise a first assembly comprising a first member and a second
member attached to the distal end of the rod. In still another
aspect, the second member can have at least two degrees of freedom
relative to the longitudinal axis of the rod. In one embodiment,
the first assembly can comprise a first member configured to be
rotatably attached to the elongate rod, and a second member
rotatably attached to the first member. In this aspect, the second
member can be releasably attached to a resistance source, such as,
for example and without limitation, a weight stack or an elastic
cord to provide a user both aerobic and anaerobic exercise.
[0006] In another embodiment, the first assembly can comprise a
first ball and socket interconnection comprising a first ball
member and a first socket member, wherein the first ball member has
at least three degrees of freedom relative to the longitudinal axis
of the rod. In this aspect, the first socket member can be attached
to the distal end of the elongate rod, and the first socket member
can be adapted to receive the first ball member such that when the
first ball member is received in the first socket member it is
capable of pivotal and rotational movement within the socket. A
first ring can be fixedly attached to the first ball member and a
resistance source can be releasably attached to the first ring.
[0007] In another aspect, the device can further comprise a second
assembly. In one aspect, the second assembly can be substantially
the same as the first assembly. The second assembly can, in another
aspect, be attached to the proximal end of the elongate rod. In
still another aspect, a second member of the second assembly can
have at least two degrees of freedom relative to the longitudinal
axis of the rod. In this aspect, the second member of the second
assembly can be releasably attached to a resistance source, such
as, for example and without limitation, a weight stack.
[0008] In still another aspect, the device can further comprise a
handle configured to be attached to the proximal end of the
elongate rod. The handle can be mounted such that a longitudinal
axis of the handle can be substantially perpendicular to the
longitudinal axis of the elongate rod so that user can simulate
canoe paddling.
[0009] In yet another aspect, the device can further comprise a
first connector having a proximal end and a distal end. The
proximal end of the first connector can be selectively and
releasably attached to the first assembly, and the distal end of
the first connector can be selectively and releasably attached to a
resistance source. In another aspect, the device can further
comprise a second connector having a proximal end and a distal end.
The proximal end of the second connector can be selectively,
releasably attached to the second assembly, and the distal end of
the second connector can be selectively and releasably attached to
a resistance source.

[0036] A fitness paddle exercise device is provided, according to
various aspects of the present invention. In one embodiment, as
shown in FIG. 1A, the exercise device 10 can comprise an elongate
rod 20 and a first assembly 40 configured to be fixedly attached to
the elongate rod. In one aspect, the first assembly comprises a
first member 42 and a second member 44. In this aspect, the second
member can be releasably attached to a resistance source, such as,
for example and without limitation, a weight stack. In one
exemplary embodiment, illustrated in FIG. 1B, the exercise device
can further comprise a second assembly 80 fixedly attached to the
elongate rod. In another aspect, the second assembly can be
substantially the same as the first assembly.
[0037] One embodiment of the elongate rod 20 is illustrated in FIG.
2A. In one exemplary embodiment, the elongate rod 20 can be
substantially cylindrical and have a proximal end 22, an opposed
distal end 24, and a longitudinal axis. In one aspect, the elongate
rod can extend for a predetermined distance. In another aspect, the
distal end of the elongate rod can define a first orifice 26 having
a longitudinal axis that is substantially co-axially aligned with
the longitudinal axis of the elongate rod and that can be
configured for receiving at least a portion of the first assembly
40 therein. In still another aspect, the proximal end of the
elongate rod 20 can define a second orifice 28 having a
longitudinal axis that is substantially co-axially aligned with the
longitudinal axis of the elongate rod and that can be configured
for receiving at least a portion of the second assembly 80
therein.
[0038] In one aspect, the elongate rod 20 can comprise at least one
shaft end member 29. In another aspect, the elongate rod can
comprise two shaft end members. In still another aspect, the at
least one shaft end member can have a proximal end configured to be
securedly attached to the first orifice 26 or the second orifice 28
of the elongate rod. In one aspect, the at least one shaft end
member 29 can be fixedly attached to an end of the elongate rod by
known methods, including, for example and without limitation,
welding the pieces together, adhering the pieces with an epoxy or
other adhesive, threading the pieces together, pressure fitting the
pieces together, screwing or bolting the pieces together, or other
conventional attachment methods.
[0039] In another aspect, the at least one shaft end member can
have a distal end that is configured to interact with the first
assembly 40 or the second assembly 80, described more fully below.
In yet another aspect, at least a portion of the at least one shaft
member can have a cross-sectional diameter substantially equal to
the cross-sectional diameter of the elongate rod 20. In another
aspect, however, the distal end of the at least one shaft member
can have a cross-sectional diameter less than the cross-sectional
diameter of the elongate rod. In still another aspect, the
cross-sectional area of the at least one shaft end member 29 can be
tapered toward the distal end of the at least one shaft end
member.
[0040] Generally, for clarity, the first assembly 40 and the second
assembly 80 are described herein as being attached to the distal
end 24 or the proximal end 22 of the elongate rod. It is of course
contemplated, as one skilled in the art will appreciate, that in
different embodiments of the device 10, the first assembly and the
second assembly, if present, can also be attached to the at least
one shaft end member 29 on the distal end and/or the proximal end
of the elongate rod 20. Additionally, it is of course contemplated
that in different embodiments of the device the first assembly and
the second assembly can also be attached to the elongate rod at
various other locations along the length of the elongate rod. For
example, in one aspect, the first assembly and/or the second
assembly can be offset from the ends of the rod a distance, which
offset optionally can be selected by the operator.
[0041] In one aspect, the elongate rod can be a single continuous
rod. In another aspect, as illustrated in FIG. 8, the elongate rod
20 can be a telescopic rod formed from a plurality of segments 30
that can be nested inside of a center segment 32 of the plurality
of segments. The center segment 32 can have a distal end 34 and a
proximal end 36, and nested segments can be extendable from both
the distal and proximal ends of the center segment. In one aspect,
upon extension of the segments, the segments 30 can be held in
place by spring-loaded retaining pins 38 that are configured to be
complementarily received in bores 39 formed in mating segments. To
collapse the telescopic rod, a user can push the spring-loaded
retaining pins inwardly towards the center of the rod, thereby
allowing the extended segments to be inserted into the center
segment. To extend the telescopic rod, a user can simply pull the
nested segments 30 out of the center segment 32 until the
spring-loaded retaining pins snap into place in the bores of the
mating segments.
[0042] In another aspect, the elongate rod 20 can be formed from a
plurality of segments 30 that are selectively detachable from each
other. In this aspect, the segments can be attached to each other
by, for example and without limitation, threads on one end of a
segment and complementary mating threads on the end of a mating
segment. In this manner, the elongate rod can be broken down into a
plurality of pieces by unthreading the segments. The elongate rod
can be assembled by threading the segments together, so that an
elongate rod, as described above, is formed. In one example, and as
illustrated in FIG. 11, the elongate rod 20 can be formed from two
mating segments, such that the two segments are of substantially
equal length. In another aspect, the segments can be attached to
each other by, for example and without limitation, bolts, screws,
pins, and the like.
[0043] One embodiment of the first assembly 40 is illustrated in
FIG. 3C. In one aspect, the first assembly can be comprised of the
first member 42 and the second member 44. In another aspect, and as
illustrated in FIG. 3A, the first member can have a proximal end
48, a distal end 46, and a longitudinal axis. In one aspect, the
proximal end of the first member can be configured to be inserted
into the orifice 26 defined in the distal end 24 of the elongate
rod 20 such that the first member 42 can be fixedly attached to the
elongate rod. In another aspect, the first member can define at
least one bore 52 having a fixed diameter configured or otherwise
sized or shaped for rotatable attachment with the second member 44.
In still another aspect, the at least one bore can comprise a
plurality of bores 52. In another aspect, between the proximal end
46 and the distal end 48 of the first member, there can be a
bearing 50 that allows the distal end of the first member to rotate
freely with respect to the proximal end of the first member, while
the proximal end of the first member 42 does not rotate and is held
in fixed contact with the elongate rod.
[0044] In another aspect, and as shown in FIG. 3B, the second
member 44 of the first assembly can be a rod 58 formed such that it
is substantially D-shaped, though it is contemplated that the
second member could be other shapes, such as, for example and
without limitation, substantially circular, substantially oval,
substantially square or substantially rectangular. In one aspect,
the rod can have a diameter that is slightly smaller than the
diameter of the plurality of bores 52 defined therein the first
member 42. In another aspect, the second member can have a first
end 54 and a second end 56 that do not meet, and thus do not form a
continuous ring. In another aspect, the first end and the second of
the second member can be positioned to form a substantially
continuous ring. The two ends of the second member can be
substantially co-axially aligned, and can be separated by a
distance that is less than the thickness of the proximal end 46 of
the first member.
[0045] In one exemplary aspect, with reference to FIGS. 3C and 1A,
this embodiment of the first assembly 40 can be assembled and
attached to the distal end 24 of the elongate rod by inserting the
proximal end 48 of the first member 42 into the orifice 26 defined
in the distal end of the elongate rod 20, such that the
longitudinal axis of the first member is substantially co-axially
aligned with the longitudinal axis of the elongate rod. The first
member can then be fixedly attached to the elongate rod by known
conventional attachment methods, including, for example and without
limitation, welding the pieces together, adhering the pieces with
an epoxy or other adhesive, threading the pieces together, pressure
fitting the pieces together, screwing or bolting the pieces
together, or other attachment methods. A first end 54 of the second
member 44 can be inserted into one of the plurality of bores 52
defined therein the first member 42, and a second end 56 of the
second member can be inserted into another bore of the plurality of
bores 52 defined therein the first member. In this aspect, upon
insertion of the second member 44 into the first member 42, the
second member can rotate around an axis substantially perpendicular
to the longitudinal axis of the first member, and thus, the
longitudinal axis of the elongate rod, and in a plane that bisects
the longitudinal axis of the rod. Thus, when assembled as described
herein, in this embodiment, the first member can rotate with
respect to the longitudinal axis of the elongate rod, and the
second member can rotate relative to both the longitudinal axis of
the elongate rod 20 and in a plane bisecting the longitudinal axis
of the elongate rod.
[0046] Another embodiment of the first assembly 40 is illustrated
in FIG. 4C. In this embodiment, the first assembly can be comprised
of the first member 42 and the second member 44. In another aspect,
the first member 42 can comprise a fastening member 60 and a
rotating member 62. In one aspect, the fastening member, such as a
screw, bolt, or the like can have a neck having a neck diameter and
can be configured to fixedly attach the first assembly to the
distal end 24 of the elongate rod 20. In one exemplary aspect, the
fastening member can fixedly attach the first assembly 40 to the
elongate rod by matingly engaging threads defined in the orifice 26
defined in the distal end of the elongate rod. In this aspect, the
fastening member 60 can be configured such that, when assembled as
described herein, a portion of the fastening member can extend
through a first bore 64 of the rotating member 62 and matingly
engage the threads in the distal end of the elongate rod. In
another aspect, the fastening member 60 can fixedly attach the
first assembly to the elongate rod by forming a pressure fit
between the fastening member and the orifice of the elongate rod
20. In still another aspect, the fastening member can fixedly
attach the first assembly 40 to the elongate rod by other known
attachment methods.
[0047] As illustrated in FIG. 4A, the rotating member 62 of the
first member 42, in one aspect, can have a longitudinal axis
extending from an upper surface 68 of the rotating member to a
lower surface 69. In another aspect, the rotating member can define
a substantially circular first bore 64 that extends from an upper
opening 61 defined in the upper surface of the rotating member to a
lower opening 63 defined in the lower surface, the first bore being
substantially parallel to the longitudinal axis of the rotating
member. In another aspect, the first bore of the rotating member 62
can have a diameter slightly larger than the diameter of the neck
of the fastening member 60. In another aspect, the rotating member
can define a second bore 66 having a longitudinal axis
substantially transverse to the longitudinal axis of the rotating
member.
[0048] The second member 44 of this embodiment of the first
assembly 40 is illustrated in FIG. 4B. In one aspect, the second
member can have a proximal end 70 and a distal end 72. In one
aspect, a slot 74 can be formed in the proximal end of the second
member, which, in one example, can bifurcate the proximal end of
the second member into two portions separated by a distance. In
another aspect, at least a portion of the bifurcated proximal end
70 of the second member 44 can be configured to receive a portion
of the rotating member 62. Still referring to FIG. 4B, the second
member can define a substantially circular rotation bore 76 having
a predetermined radius and a longitudinal axis. In one aspect, the
rotation bore can extend from a front surface 77 of the second
member 44 through the slot 74 and to a rear surface 78 of the
second member. As shown in FIG. 4C, the rotation bore can be
configured to receive a rotation element 73, such as for example
and without limitation, a pin, screw, bolt, or the like, about
which the second member can rotate. In still another aspect, the
second member 44 can define a substantially circular connection
bore 79 configured for receiving a first connector or a second
connector, described more fully below. In another aspect, a
longitudinal axis of the connection bore can be substantially
parallel to the longitudinal axis of the rotation bore 76.
[0049] In one exemplary aspect, with reference to FIG. 4C, this
embodiment of the first assembly 40 can be assembled and attached
to the distal end 26 of the elongate rod 20 by inserting the neck
of the fastening member 60 therethrough the first bore 64 of the
rotating member 62 in a direction from the upper surface 68 of the
rotating member to the lower surface 69, until at least a portion
of the fastening member protrudes from the lower opening 63 of the
rotating member. At least a portion of the neck of the fastening
member that protrudes from the lower opening can be fixedly
attached to the orifice 26 defined therein the distal end of the
elongate rod. In one aspect, the fastening member 60 can fixedly
attach the rotating member 62 to the elongate rod while still
allowing the rotating member to rotate about the longitudinal axis
of the rod. In another aspect, a portion of the rotating member can
be inserted into the slot 74 of the second member 44 such that the
second bore 66 of the first member is co-axially aligned with the
rotation bore 76 of the second member. In another aspect, the
rotation element 73 can be inserted therethrough the co-axially
aligned bores to create a hinge about which the second member can
rotate. In still another aspect, the second member 44 can rotate in
a plane bisecting the longitudinal axis of the first bore 64 of the
rotating member of the first member 42. Thus, when assembled as
described herein, in this embodiment, the first member can rotate
with respect to the longitudinal axis of the elongate rod, and the
second member can rotate relative to both the longitudinal axis of
the elongate rod 20 and in a plane bisecting the longitudinal axis
of the elongate rod.
[0050] FIG. 5A illustrates another embodiment of the first assembly
40. In this embodiment, the first assembly can be comprised of a
first ball and socket interconnection member 140 and a second
member 142. The first ball and socket interconnection member can be
comprised of a first ball member 144 and a first socket member 146.
In one aspect, the first socket member can be adapted to receive
the first ball member and have a mounting arm 152 protruding from
the socket member configured to be inserted into the orifice 26
defined in the distal end of the elongate rod 20. In this aspect,
when the first ball member is received within the first socket
member, the first ball member can have at least three degrees of
freedom, i.e. it can be capable of both pivotal and rotational
movement within the socket. In another aspect, the first ball
member 144 can have a first spacing arm 148 protruding from the
ball. The first spacing arm can have a distal end 150 extending a
predetermined distance from the ball. In one aspect, as illustrated
in FIG. 5A the first spacing arm can be substantially straight. In
another aspect, as illustrated in FIG. 5B, the first spacing arm
148 can have at least one bend in it.
[0051] In this embodiment, the second member 142 can be a rod
formed such that it is substantially D-shaped, though it is
contemplated that the second member could be other shapes, such as,
for example and without limitation, substantially circular,
substantially oval, substantially square or substantially
rectangular. In one aspect, the second member 142 can have two ends
that are adjacent to each other, forming a continuous ring, and the
second member can be attached to the first spacing arm 148 by
conventional means, such as, for example and without limitation,
welding or otherwise adhering.
[0052] This embodiment of the first assembly 40 can be assembled
and attached to the distal end 24 of the elongate rod 20 by
inserting the mounting arm 152 of the first socket member 146 into
the orifice 26 defined in the distal end of the elongate rod. The
first socket member can be fixedly attached to the elongate rod by
known attachment methods, as discussed above. The first socket
member can receive the first ball member 144 in the socket of the
first socket member, and the second member 142 can be attached to
the first spacing arm 148 by known methods including, for example
and without limitation, welding or otherwise adhering them
together. When assembled as described herein, in this embodiment,
the first ball member can have at least three degrees of freedom
relative to the longitudinal axis of the elongate rod 20, i.e. it
can be capable of both pivotal and rotational movement within the
socket.
[0053] FIG. 6 illustrates another embodiment of the first assembly
40. In this embodiment, the first assembly can comprise a rotating
neck 160, a fastener 162, and a second member 164. In one aspect,
the rotating neck can be substantially circular having an inner
diameter, an outer diameter, and a longitudinal axis. The fastener
can be, without limitation, a bolt, screw, pin or the like. The
second member 164 can be a rod formed into a substantially circular
shape, and having a first end 166 attached to the rotating neck and
a second end 168 attached to an opposed side of the rotating neck.
Although a substantially circular second member 164 is illustrated,
other shapes, including, for example and without limitation,
substantially oval, substantially square or substantially
rectangular are contemplated. In this aspect, the second member can
be attached to the rotating neck 160 by conventional means, such
as, for example and with limitation, welding or otherwise adhering
them together.
[0054] This embodiment of the first assembly 40 can be assembled
and attached to the distal end 24 of the elongate rod 20 by placing
the rotating neck 160 over the orifice 26 defined in the distal end
of the elongate rod. In one aspect, a portion of the fastener 162
can be inserted through the inner diameter of the rotating neck
into the orifice 26 defined therein the distal end of the elongate
rod to fixedly attach the first assembly to the elongate rod. The
fastener can be fixedly attached to the elongate rod 20 by known
attachment methods, including for example and without limitation,
welding, adhering, threading and other conventional attachment
methods.
[0055] In another aspect, the exercise device 10 can further
comprise a second assembly 80 configured to be fixedly attached to
the proximal end 22 of the elongate rod 20. In this aspect, with
both the first assembly and the second assembly attached to
respective ends of the elongate rod 20, a user of the device 10 can
be provided resistance from both ends of the rod, as would occur in
paddling a kayak.
[0056] In one aspect, the second assembly 80 can be formed
similarly to any of the embodiments of the first assembly 40, as
previously described. In another aspect, the exercise device 10 can
be further assembled by fixedly attaching the second assembly 80 to
the proximal end 22 of the elongate rod. The second assembly can be
attached to the elongate rod 20 in any of the manners described
above with reference to attaching the first assembly 40 to the
elongate rod.
[0057] In other aspects, it is contemplated that the first assembly
40 can be selectively placed, in addition to the distal end 24 of
the elongate rod, at any one of a plurality of locations along the
length of the elongate rod. In one exemplary aspect, the elongate
rod can define a plurality of mounting bores spaced along the
length of the elongate rod, such that the first assembly can be
selectively bolted to the elongate rod at a desired one of the
plurality of mounting bores. In another aspect, the first assembly
can further comprise a clamping element, such that the first
assembly can be selectively clamped to the elongate rod at any
location the user selects. In still other aspects, it is
contemplated that the first assembly 40 can be selectively attached
to the elongate rod at any location by other conventional
attachment methods. Thus, the first assembly can be offset along
the longitudinal axis of the elongate rod 20 a predetermined
distance from the distal end 24 of the rod.
[0058] Similarly, in various other aspects, it is contemplated that
the second assembly 80 can be placed, in addition to the proximal
end 22 of the elongate rod, at any one of a plurality of locations
along the length of the elongate rod. In one exemplary aspect, the
elongate rod 20 can define a plurality of mounting bores spaced
along the length of the elongate rod, such that the second assembly
can be selectively bolted to the elongate rod at a desired one of
the plurality of mounting bores. In another aspect, the second
assembly can further comprise a clamping element, such that the
second assembly can be selectively clamped to the elongate rod at
any location the user selects. In still other aspects, it is
contemplated that the second assembly 40 can be selectively
attached to the elongate rod at any location by other conventional
attachment methods. Thus, the second assembly can be offset along
the longitudinal axis of the elongate rod 20 a predetermined
distance from the proximal end of the rod.
[0059] In still another aspect, the device 10 can further comprise
at least one cushioning grip 180, illustrated in FIG. 9. The at
least one cushioning grip can be formed from a soft cushioning
material, for example and without limitation, foam. The at least
one cushioning grip can have a substantially tubular shape
configured to fit over the elongate rod 20. In one aspect, the at
least one cushioning grip can have an inner diameter that is
substantially the same as the diameter of the elongate rod, and the
at least one cushioning grip 180 can be adhered to the elongate rod
using conventional adhesives. In another aspect, the at least one
cushioning grip can be formed with a slit in a longitudinal
direction through the thickness of one side of the at least one
cushioning grip so that the at least one cushioning grip 180 can
easily be placed over the elongate rod, at any location along the
length of the elongate rod.
[0060] In yet another aspect, the exercise device 10 can further
comprise a handle 200, as illustrated in FIG. 7, configured for
selective, releasable attachment to the proximal end 22 of the
elongate rod 20. In one aspect, the handle can have a longitudinal
axis that, when attached to the elongate rod, is substantially
perpendicular to the longitudinal axis of the elongate rod. In
another aspect, the handle can be configured to simulate the shape
and feel of the end of a canoe paddle, and can be attached to the
elongate rod by, for example and without limitation, a bolt, screw,
or other similar restraining device. In yet another aspect, the
handle can be threaded, and the proximal end 22 of the elongate rod
can be complementarily threaded, such that the handle 200 can be
screwed onto the proximal end 22 of the elongate rod 20. In another
aspect, for example, if a user desires resistance from only one end
of the device, as in paddling a canoe, instead of attaching the
second assembly to the proximal end of the elongate rod, the handle
200 can be detachably secured to the proximal end of the elongate
rod. Additionally, a user can choose to alternate between
selectively attaching the second assembly 80 and the handle 200 to
the proximal end of the elongate rod, so that resistance can be
alternatively, selectively provided from both ends of the device
and then only one end.
[0061] In another aspect, as illustrated in FIG. 10, the exercise
device 10 can further comprise a first connector 210 having a
proximal end and a distal end. In various aspects, the first
connector can be an elastic cord, rope, wire or the like. In one
aspect, the proximal end of the first connector can be selectively,
releasably attached to the first assembly 40 of the exercise
device. In another aspect, the distal end of the first connector
can be selectively, releasably attached to a resistance source 214,
such as, for example and without limitation, a weight stack or, if
the first connector 210 is an elastic cord, a stationary object,
such as, for example and without limitation, a door knob, a
doorjamb, a table leg, and the like. In one aspect, then, when
assembled as described herein, the first connector can be movable
about at least three degrees of freedom relative to the
longitudinal axis of the elongate rod 20, i.e., the first member 42
of the first assembly 40 can rotate about the longitudinal axis of
the elongate rod; the second member 44 of the first assembly can
rotate about a plane bisecting the longitudinal axis of the
elongate rod; and the first connector 210 can rotate within the
connection bore 79 of the second member 44.
[0062] In another aspect, the device can further comprise a second
connector 212 having a proximal end and a distal end. In various
aspects, the second connector can be an elastic cord, rope, wire or
the like. In one aspect, the proximal end of the second connector
can be selectively, releasably attached to the second assembly 80.
In another aspect, the distal end of the second connector can be
selectively, releasably attached to a resistance source, as
described above. Thus, in one aspect, when assembled as described
herein, the second connector can be movable about at least three
degrees of freedom relative to the longitudinal axis of the
elongate rod 20, i.e., the first member 42 of the second assembly
80 can rotate about the longitudinal axis of the elongate rod; the
second member 44 of the second assembly can rotate about a plane
bisecting the longitudinal axis of the elongate rod; and the second
connector 212 can rotate within the connection bore 79 of the
second member 44. Optionally, in other aspects, the second
connector 212 can be attached to the same resistance source that
the first connector 210 is attached to, or alternatively, the
second connector can be attached to a different resistance source
than the first connector.
[0063] In one aspect, the components of the exercise device can be
formed from steel, such as, for example, stainless steel. It is
contemplated, as can be appreciated by one skilled in the art, that
the components of the exercise device 10 can be formed from other
metals, such as, for example and without limitation, aluminum,
titanium and the like. It is further contemplated that the
components of the exercise device can be formed from polymeric
materials, including fiber-reinforced polymers, such as, for
example and without limitation, fiberglass. It is further still
contemplated that the elongate rod 20 can be formed from wood. It
is also contemplated that the exercise device can be formed from a
combination of wooden, metallic components and polymeric
components.
[0064] In order to use the exercise device 10, a user can attach
the exercise device to a resistance source 214, such as, for
example and without limitation, a weight stack. In one aspect, the
user can releasably attach a cable from a weight stack, as are
commonly known in the art, to the first assembly 40. In another
aspect, it is contemplated that the user can position the first
assembly at a desired location along the length of the elongate
rod. The user can, if desired, selectively, releasably attach the
handle 200 to the proximal end 22 of the elongate rod. The user can
then sit, kneel or stand a distance away from the weight stack and
move the device to cause the weight stack to rise repetitively,
thereby providing both aerobic and anaerobic exercise. In this
aspect, the user can move the device 10 in a motion similar to that
used in paddling a canoe. However, the user can move the device
through various other directions in the frontal, sagittal and
horizontal planes.
[0065] Optionally, in another aspect, the user can releasably
attach the proximal end of the first connector 210 to the first
assembly 40, and the distal end of the connector to a resistance
source 214. If the first connector is an elastic connector, the
distal end of the connector can be releasably attached to a
stationary resistance source, such as, for example and without
limitation, the frame of a weight stack, a door knob, a doorjamb, a
table leg, and the like. If the first connector 210 is a
non-elastic connector, such as, for example and without limitation,
a rope or wire, the distal end of the first connector can be
releasably attached to a mobile resistance source, such as, for
example and without limitation, a weight stack. The user can then
sit, kneel or stand a distance away from the resistance source and
move the device repetitively, thereby providing both aerobic and
anaerobic exercise. In this aspect, the user can move the device in
a motion similar to that used in paddling a canoe. Again, however,
the user can move the device through various other directions in
the frontal, sagittal and horizontal planes.
[0066] In various other aspects, in addition to having a first
resistance source attached to the first assembly 40, as described
above, the user can attach a second resistance source to the second
assembly 80. Additionally, in another aspect, it is contemplated
that the user can position the second assembly at a desired
location along the length of the elongate rod. In one aspect, the
second resistance source can be the same resistance source as the
first resistance source. In another aspect, the user can releasably
attach a cable from a weight stack, to the second assembly of the
exercise device 10. The user can then sit, kneel or stand a
distance away from the weight stack and move the device to cause
the weight stack to rise repetitively, thereby providing both
aerobic and anaerobic exercise. In this aspect, the user can move
the device 10 in a motion similar to that used in paddling a kayak.
However, the user can move the device through various other
directions in the frontal, sagittal and horizontal planes.
[0067] In yet another aspect, the user can releasably attach the
proximal end of the second connector 212 to the second assembly 80,
and the distal end of the connector to a second resistance source.
If the second connector is an elastic connector, the distal end of
the connector can be releasably attached to a stationary resistance
source, such as, for example and without limitation, the frame of a
weight stack, a door knob, a door jamb, a table leg, and the like.
If the second connector is a non-elastic connector, such as, for
example and without limitation, a rope or wire, the distal end of
the connector can be releasably attached to a mobile resistance
source, such as, for example and without limitation, a weight
stack. The user can then sit, kneel or stand a distance away from
the resistance source and move the device repetitively, thereby
providing both aerobic and anaerobic exercise. In this aspect, the
user can move the device 10 in a motion similar to that used in
paddling a kayak. Again, however, the user can move the device
through various other directions in the frontal, sagittal and
horizontal planes.
