DETAILED DESCRIPTION OF ILLUSTRATIVE IMPLEMENTATIONS
[0014] FIG. 1 is a perspective view of an illustrative core
training apparatus. FIG. 1 depicts a core training apparatus 100
which includes a support base that includes laterally extending
support arms. The rearwardly extending arm is longer than the
remaining three arms and slidably engages seat 102 which is secured
in a desired position along the rearwardly extending arm with a pin
that mates with one of a number of receiving apertures 109 located
along the rearwardly extending arm. The seat 102 can be moved as
shown by arrow 111 into various positions (e.g., as depicted in
broken lines by a seat 103) along the rearwardly extending arm
defined by pin receiving holes 109.
[0015] The support base also includes a vertically extending member
which includes a ball member akin to that conventionally used as
vehicular trailer hitches. Atop that ball member is mounted a
center post which includes a seat 101 opposite a socket member with
a recess into which the ball is received. In certain embodiments
the socket member has one or more inwardly projecting locking
mechanisms such as set screws which prevent the socket from lifting
off of the ball. In the depicted example, the center post includes
a locking pin 129 extending radially through a slot 130 in the
center post. Examples of locking pin mechanisms are described in
further detail with reference, for example, to at least FIG. 6. As
depicted here, the locking pin 129 is in a lower position, which
may correspond to the center post being in a locked state to
prevent movement of the center post with respect to the ball. This
locked state may provide, in some embodiments, a stable seat 101,
for example, when a user mounts or dismounts from the seat 101.
[0016] Extending forwardly from the center post is a member that
supports a handlebar/footrest 106. As shown by arrow 113 the
handlebar/footrest 106 can articulate between an upper position in
which the member serves as a handlebar and a lower position (e.g.,
as depicted in broken lines in the position as a footrest 107) in
which the member serves as a footrest. In the depicted example, the
handlebar/footrest 106 is locked into the desired position with a
spring loaded reciprocating pin.
[0017] Extending laterally from the center post are downwardly
projecting arms which have handles 104 slideably mounted thereto.
The handles 104 can be moved as shown by arrow 112 into various
positions (e.g., as depicted in broken lines by handles 105) along
the arms defined by pin receiving holes 110. At the distal (lower)
ends of the downwardly projecting arms are ballast holding posts
that project perpendicularly and laterally from the arms. The posts
are configured to receive plates 108 that provide weight which is
subject substantially to gravitational and inertial forces. In
operation, the user may perform static and/or dynamic exercises by
generating forces that overcome resistance associated with the
gravitational and/or inertial forces on the ballast(s), such as the
plates 108, for example.
[0018] FIG. 2 is a perspective view of the illustrative core
training apparatus which depicts a first operational mode. As
depicted, FIG. 2 shows an operational mode in which a user 221
performs a rowing exercise. The user 221 sits on the rearwardly
extending arm and places his hands on the handles 204 and pulls one
back while permitting the other to move forward in a motion similar
to rowing a kayak with a dual-ended paddle. Viewed from the sides,
the handles 204 progress through an oval-shaped range of motion. In
other exercises the handles 204 may be articulated horizontally
back and forth as shown by arrows 214. The handles 204 may be
positioned at different heights to alter the difficulty, the range
of motion and the muscles exercised. Examples of illustrative
motion trajectories are described in further detail with reference,
for example, to FIG. 5.
[0019] In the depicted example, the center post includes a locking
pin 229 extending radially through a slot 230 in the center post.
As depicted here, the locking pin 129 is in a raised position,
which may correspond to the center post being in an unlocked state
to permit movement of the center post with respect to the ball.
This unlocked state may provide, in some embodiments, an
articulating assembly coupled to the center post rotatably
supported by the ball, for example, responsive to user applying
dynamic forces via the handles 204, for example. In various
embodiments, the seat 201 remains fixed when locked by the locking
pin 229, and otherwise the seat 201 is able to move freely subject
primarily to gravitational and inertial forces on the ballast
208.
[0020] FIGS. 3A-3B show another operational mode in which a user
sits atop the seat 301 and articulates the arm assembly through use
of her core muscles. In this embodiment the handlebar/footrest 306
is secured into an upper position. The user pivots her upper torso
relative to her lower torso in order to articulate the apparatus in
a side-to-side motion illustrated by arrows 315. FIG. 3A
illustrates a point in the range of motion in which the apparatus
is fully articulated to the user's left hand side. FIG. 3B
illustrates a point in the range of motion in which the apparatus
is articulated to the user's right-hand side.
[0021] FIGS. 4A-4B show another operational mode in which a user
sits atop the seat 401 and articulates the arm assembly through use
of her core muscles. In this embodiment the handlebar/footrest 406
is secured into a lower position and the user's feet rest on the
footrest 406. The user pivots her upper torso relative to her lower
torso in order to articulate the apparatus in a front-to-back
motion illustrated by arrows 416. FIG. 4A illustrates a point in
the range of motion in which the apparatus is articulated to the
front (taking the user as the frame of reference). FIG. 4B
illustrates a point in the range of motion in which the apparatus
is articulated to the rear (again, taking the user as the frame of
reference).
[0022] FIG. 5 is a plan view of the core training apparatus 500
which shows various alternative exercise motions similar to those
illustrated in FIGS. 3 and 4. As an alternative to or in addition
to the side-to-side and front-to-back motions shown in FIGS. 3 and
4, the user may articulate the apparatus through a figure eight
motion 519. By way of example and not limitation, the user can also
articulate the apparatus in a rectangular pattern 517/518 wherein
the apparatus is not permitted to return to the center position but
instead the apparatus is articulated along the outline of rectangle
520. The apparatus may also be articulated in a circular pattern
516, during which the apparatus is likewise not permitted to return
to the center or neutral position (shown in FIG. 1) during the
exercise.
[0023] FIG. 6 is a front cross-sectional view of an exemplary
angular coupling system in an illustrative core training apparatus.
An exemplary angular coupling system 600 for use in various
embodiments of the core trainer and/or the row trainer includes a
rigid support base member 622 having at a top end a ball 623.
Movably coupled to the ball member 623 is a socket member 627, with
a cup-shaped aperture to receive the ball member 623. The socket
member is adapted to deflect around three orthogonal axes, for
example, or other three dimensional coordinate axes, defined with
respect to the ball 623. This motion can be restricted when a
locking pin 629 is positioned in a locking channel 628 in the ball
623. The locking pin 629 position is controlled by a
user-accessible lever. When retracted up so that the pin is clear
of the locking channel 628, then relative movement of the socket
member 627 relative to the ball 623 is not restricted by the pin
629. The user manipulation of the lever is guided by an L-shaped
locking pin slot 130, as shown, for example, with reference to
FIGS. 1-2.
[0024] The socket member is coupled to an actuating member 624,
examples of which are described with reference to a center post
with reference to FIG. 1. In the depicted example, laterally
extending members 626 that support ballast (not shown) are
integrally connected to the socket member 627.
[0025] In the depicted example, the socket member 627 receives a
removable annular retaining ring 625 adjacent the opening of the
aperture and proximate a neck region just below and supporting the
ball 623 on the rigid base member 622. The retaining ring 625 has
an inner diameter slightly less than an outer diameter of the ball
623 to prevent the socket member 627 from inadvertently decoupling
from the ball 623, for example, during ballast changes, exercise,
and mounting or dismounting operations.
[0026] FIGS. 7-9 are front and side views of illustrative core
training apparatus with illustrative row training apparatus. As
depicted in FIG. 7, an exemplary exercise system includes a core
trainer and a row trainer. The core trainer includes a seat 701 for
a human user, and a dual handrest/footrest 706. Supported by an
articulating assembly movably coupled to a ball joint are the seat
701 and opposing ballasts 708, which may provide controlled amounts
of inertia and/or gravitational weight. In operation, the user
exercises core muscles to impart motion profiles to the
articulating assembly of the core trainer.
[0027] The row trainer as depicted includes an articulating rowing
assembly movably coupled to a ball joint and opposing ballasts 708,
which may provide controlled amounts of inertia and/or
gravitational weight. In operation, the user grasps handles 704 and
pulls and pushes to exercise, for example, upper body and/or core
muscles to impart motion profiles to the articulating assembly of
the row trainer.
[0028] FIG. 8 shows an exemplary exercise system with a locking pin
829 and locking pin slot 830 accessible from under the seat 801 on
the right side of a user when seated on the seat 801. The pin 830
is shown in an upward retracted state, which corresponds to an
unlocked state of the ball/socket. In this depicted example, the
handrest 806 is positioned in an upper position for easy grasping
by the user.
[0029] In the depicted example, the ballast of the core trainer is
supported on posts that are coupled to opposing laterally extending
members of a fixed length. In some other embodiments, the length of
the laterally extending members may be adjustable.
[0030] The row trainer is positioned in front of the user seated on
the seat 801, with handles 804 within reach of the user seated on
the seat 801. By applying force via the handles 804, the user may
cause motion of the articulating assembly that supports the ballast
808 on the row trainer. In this depicted example, the row trainer
includes adjustable laterally extending members along which the
user can adjust the handles 804. By adjusting the handles down, the
user can select a wider separation between the left and right
handles 804, for example. This adjustable separation of the handles
804 may advantageously accommodate different exercises and a range
of user body sizes.
[0031] FIG. 9 illustrates an exemplary user seated on the core
trainer and grasping the row trainer. The user has positioned the
handrest/footrest 806 into a lower position for use as a
footrest.
[0032] On the top of the row trainer is an L-shaped lever coupled
to a locking pin for immobilizing the ball/socket on the row
trainer, for example, during ballast changes. In the retracted
state (as shown) the articulating assembly on the row trainer is
free to be used for exercise. When rotated to be inserted into a
locking channel in the ball, the row trainer articulating assembly
may be locked. Examples of this operation are described in further
detail with reference to FIG. 6.
[0033] Although various embodiments have been described with
reference to the figures, other embodiments are possible. For
example, the handles 104 may be positioned laterally outwards of
the position shown in FIG. 1. In such an embodiment a laterally
extending member couples each handle to the channel member which
slideably engages the downwardly extending arms. In various
embodiments the handles may be positioned approximately 2-4 feet
apart, measured at the horizontal center point of each handle. In
preferred embodiments the handles are approximately 2.5-3.5 feet
apart, and in more preferred embodiments about 2.5 to 3 feet apart.
In some embodiments, separation of the handles 104 may be
adjustable to any of a number of user-selectable positions
corresponding to a range of separation distances.
[0034] The horizontal offset of the handle from the downwardly
extending arm may also be varied to alter the range of motion and
muscles exercised. In the depicted embodiment the handles are
offset by a distance of approximately 6 inches from the centerline
of the downwardly extending arms. In other embodiments, this
horizontal offset is approximately 8, 10, 12, 14, 16 or 18
inches.
[0035] Some embodiments may provide other grip styles and/or
orientations for the handles 104, for example. For example, some
implementations may include multiple or variable angle grip
positions for the handles 104. Some embodiments may include a
flexible (e.g., rope) attachment to be grasped by the user during
exercise while seated on the seat 102.
[0036] Some examples may include foot placements to receive the
ball, heel, toes, and/or the entire bottom surface of the foot of
the user during exercise while seated on the seat 102. By way of
example, and not limitation, the foot placements may include plates
with or without straps to capture the top of each foot, or a bar
member extending radially from the central base support member to
provide a toe hold, for example.
[0037] To aid the loading and unloading of plates 108 from the
plate holding posts the center post assembly may include a
downwardly extending and reciprocating pin (e.g., the locking pin
129) which engages a vertical bore in the ball member. In this way
the user can articulate the pin downward to lock the arm assembly
in the center or neutral position during a plate unloading or
loading operation and when mounting or dismounting the apparatus.
When ready to begin an exercise movement, the user can articulate
the pin upwards, thereby allowing the socket to rotate freely with
respect to the ball.
[0038] The angle between the downwardly extending arms and vertical
support post may be, in preferred embodiments, about 10-45 degrees
and in more preferred embodiments about 15-25 degrees and in the
most preferred embodiments about 15-20 degrees. This angle may also
be manually adjustable by a user, as shown in the provisional
applications incorporated herein by reference. In such embodiments
the downwardly extending arms are hingedly coupled to the center
post member and pins are used to secure the arms at the desired
angle.
[0039] The apparatus may also include damper elements and/or
tension spring elements that extend between the vertical support
posts and either or both of the downwardly extending arms and the
forwardly extending arm which holds the handlebar/footrest 106.
Dampers may provide increased resistance at higher rates of motion
and may also prevent the apparatus from pivoting quickly, thereby
reducing the risk of injury during loading/unloading or
mounting/dismounting operations. Tension spring elements will tend
to cause the device to return to the center or neutral position and
will thereby provide a substantially modified feel and exercise for
the user. Either or both of the tension springs elements or the
damper elements may be configured to be toolles sly removable and
installable so that a user can readily remove or add spring or
damper elements as desired. For instance, the ends of the spring
elements and damper elements may include apertures that align with
complementary apertures on flanges disposed on the downwardly
extending arms and the vertical support post so that a user may
readily insert pins to secure each spring or damper element in
place. Some embodiments may include an angular displacement sensor
to detect the angular deflection of the articulating assembly,
(e.g., the seat 101 or the row assembly), relative to a set of
orthogonal axes defined by the articulating assembly's base
member.
[0040] Some embodiments may further include sensors to detect
position, velocity, and/or forces associated with static or dynamic
exercises. In some examples one or more sensor assemblies may
operate to detect the weight of the ballast loaded on the core
trainer and/or the row trainer. Various sensor outputs may be
received by a central processor executing a program of instructions
for recording and communicating performance metrics and other
feedback to the user. By way of example, and not limitation, the
processor may be configured to send audible, visual, and/or tactile
feedback to the user with indicia representative of athletic
performance. For example, the processor may be coupled to a display
device to display a plot of instantaneous and/or historical angular
deflection of the articulating assemblies of the core trainer
and/or the row trainer. The processor may output real time and/or
historical averages or cumulative totals of user-selected
parameters, such as revolutions per minute, number of revolutions,
average angular deflection, calories expended, equivalent distance
rowed in a kayak, or the like, for example. In some
implementations, the display may provide a programmed display of
training information, such as a pre-programmed series of motion
profiles with deflection plots that the user should follow. The
processor may provide a score based on the user's exercise
performance variance with respect to the training profile.
Increasing levels of difficulty may be associated with increased
angular deflections, faster velocities, alone or in combination
with more taxing motion profile sequences.
[0041] The features of the foregoing embodiments can be combined as
desired to achieve additional embodiments. For instance, the core
chair exercise device of FIG. 9 can be modified to include the
non-pivoting seat and corresponding handles of FIG. 1, such the
that the user can optionally sit in this additional seat, rearward
of seat 801, to execute a rowing exercise using ballast 808 while
seated in a position close to the floor.
[0042] A skilled artisan will understand that the motion of the
core trainer and row trainer devices described herein will be
subject substantially only to the gravitational and inertial forces
acting upon and through the ballast. The shear friction associated
with the ball joint interface is minimal in the preferred
embodiments. The effect of mass of the device itself, as opposed to
the ballast, will be in most embodiments be insignificant relative
to the effect of the mass of the ballast given the positioning of
the ballast and the associated polar moment of inertia.
[0043] A number of embodiments have been described. Nevertheless,
it will be understood that various modifications are optionally
made without departing from the spirit and scope of this
disclosure. Accordingly, other embodiments are within the scope of
the following claims.
