FIELD OF USE
[0002] The present disclosure relates generally to exercise
equipment. More specifically, the present disclosure relates to
barbell attachment devices that provide various weight resistances
on a barbell, relative to the horizontal plane of the barbell.
SUMMARY
[0003] To minimize the limitations in the prior art, and to
minimize other limitations that will become apparent upon reading
and understanding the present specification, the following
discloses a barbell collar that provides various weight resistances
in relation to the center of gravity of a barbell.
[0004] One embodiment of the present disclosure may be a barbell
collar, comprising: a plate; and at least two weight bars, a first
weight bar and a second weight bar; wherein the plate comprises a
barbell engagement portion, a heavy arm, and a light arm; wherein
the heavy arm weighs more than the light arm; wherein the barbell
engagement portion is configured to engage with a barbell; wherein
each of the at least two weight bars is attached to each of the at
least two arm portions of the plate; and wherein the at least two
weight bars are adapted to engage and hold one or more weights. The
barbell engagement portion may be located approximately near a
first end of the light arm and approximately near a first end of
the heavy arm. The first weight bar may be located approximately
near a second end of the light arm and wherein the second weight
bar may be located approximately near a second end of the heavy
arm. The light arm may be aligned between approximately 91 to 179
degrees from the heavy arm. The light arm may be aligned between
approximately 130 to 140 degrees from the heavy arm. The light arm
may be aligned between approximately 135 degrees from the heavy
arm. The at least two weight bars may be substantially
perpendicular to the at least two arm portions of the plate. The
light arm and the heavy may be approximately the same length or be
different lengths.
[0005] In one embodiment, the barbell and multiple fixed resistance
components may allow a greater diversity in influencing the
resistance curve compared to other systems because, although the
same amount of resistance may be added to the barbell in each
system, the resistance may be configured in the system of the
present disclosure in a manner that shifts the center of mass
because the gear-like design allows subsequent resistance
arms/resistance to be placed in multiple positions relative to each
other.
[0006] Compared to previous resistance systems, one embodiment of
the system of the present disclosure may allow for a more
predictable manner of loading and unloading resistance to the
barbell. Because of the structure of the sleeve interface with the
applied resistance arms, the barbell may have the capacity to
accept accessory arms to be independently placed upon the sleeves
to further influence the positioning of the center of mass and
therefore the perceived resistance curve.
[0007] The system may function differently as compared to a
traditional barbell loaded with standard weight plates for two main
reasons: an offset of the center of mass from the location of the
applied force and the mass imbalance between the two arms of the
plate (one arm being heavier than the other). Because the center of
mass may be offset from the location of applied force, the system
undergoes some rotational motion when it is subjected to an arc
path of movement, like that experienced during a multitude of
exercises. This rotation produces a torque vector through the axis
of rotation, resulting in the user having to compensate for this in
addition to performing the given exercise. Also, because of the
mass imbalance between the two arms, the moment of inertia for the
system is skewed towards the heavier arm. This results in a
perceived lag effect that the user experiences when performing an
arc-path based exercise as the user needs to overcome the
rotational inertia caused by the heavier arm.
[0008] Other features and advantages that are inherent in the
barbell collar claimed and disclosed will become apparent to those
skilled in the art from the following detailed description and its
accompanying drawings.

DETAILED DESCRIPTION OF THE ILLUSTRATIVE EMBODIMENTS
[0039] In the following detailed description, numerous specific
details are set forth in order to provide a thorough understanding
of various aspects of one or more embodiments. However, these
embodiments may be practiced without some or all of these specific
details. In other instances, well-known methods, procedures, and/or
components have not been described in detail so as not to
unnecessarily obscure aspects of embodiments.
[0040] While multiple embodiments are disclosed, still other
embodiments will become apparent to those skilled in the art from
the following detailed description. As will be realized, these
embodiments are capable of modifications in various obvious
aspects, all without departing from the spirit and scope of
protection. Accordingly, the screen shots, figures, and the
detailed descriptions thereof, are to be regarded as illustrative
in nature and not restrictive. Also, the reference or non-reference
to a particular embodiment shall not be interpreted to limit the
scope of protection.
[0041] In the following description, certain terminology is used to
describe certain features of one or more embodiments. For purposes
of the specification, unless otherwise specified, the term
"substantially" refers to the complete or nearly complete extent or
degree of an action, characteristic, property, state, structure,
item, or result. For example, in one embodiment, an object that is
"substantially" located within a housing would mean that the object
is either completely within a housing or nearly completely within a
housing. The exact allowable degree of deviation from absolute
completeness may in some cases depend on the specific context.
However, generally speaking, the nearness of completion will be so
as to have the same overall result as if absolute and total
completion were obtained. The use of "substantially" is also
equally applicable when used in a negative connotation to refer to
the complete or near complete lack of an action, characteristic,
property, state, structure, item, or result.
[0042] As used herein, the terms "approximately" and "about"
generally refer to a deviance of within 15% of the indicated number
or range of numbers. In one embodiment, the term "approximately"
and "about", refer to a deviance of between 0.0001-40% from the
indicated number or range of numbers.
[0043] In the following description, certain terminology is used to
describe certain features of one or more embodiments. For example,
the term "barbell" generally refers to any long and strong metal
bar to which disks of varying weights may be attached at each end,
and may be used for weightlifting. Examples of barbells may
include, without limitation, standard barbells, curl bars, EZ curl
bars, fixed barbells, thick-handled barbells, triceps bars, trap
bars, Olympic style barbells with a 2-inch axle bearing, and/or
standard barbells with a 1-inch axle bearing.
[0044] The present specification discloses a new and improved
barbell collar, which may be one or more devices configured to be
attached to a barbell. Specifically, the barbell collar may be
generally configured to attach to the end portions of an existing
barbell and may be used in pairs with respect to a single barbell.
In one embodiment, each barbell collar may comprise at least two
arm portions, wherein each arm portion may comprise a weight bar.
Each weight bar may be tubular and may be configured to hold and
secure one or more disc weights. In a preferred embodiment, one arm
portion may be greater in mass than the other arm portion and may
be angled in approximately 135.degree. degrees from each other. The
barbell collar may also be configured to rotate 360.degree. degree
around the barbell and releasable lock in various positions around
the barbell.
[0045] The barbell collar may be used in several ways. The barbell
collar may be utilized with only one of the arm portions loaded
with disc weights. The barbell collar may be also used with the
both of the arm portions loaded with disc weights. In various
exercises, the amount of disc weights added to the arm portions may
change. Adding and subtracting weights to the arm portions may
affect the position of the barbell collar(s) as the exercise is
being performed. Additionally, the user may influence the position
of the arm portions in a manner, in which the user moves the actual
barbell. For example, gravity may pull one arm portion down,
potentially, keeping that arm portion at an approximately
90.degree. degrees with respect to the ground's surface. However,
the user may also influence the movement of the barbell by causing
the barbell collar to move in an arc through various angles of free
movement. The amount of weight or resistance applied to one arm
portion may also influence the position of the other arm portion.
Finally, the barbell collar may be used in a manner that promotes a
more controlled movement of the barbell in that the user may
attempt to minimize the movement of the arms through a controlled
and deliberate manner of the actual barbell movement.
[0046] FIG. 1 is an illustration of a top perspective view of one
embodiment of a barbell collar. As shown in FIG. 1, the barbell
collar 100 may comprise: a plate 101, a first weight bar 106, and
second weight bar 108. The plate 101 may comprise: a barbell
engagement portion 150, light arm 102, and heavy arm 104. The plate
101 is generally constructed of any rigid material, such as metal
(e.g., steel, iron, aluminum), but may be constructed of any type
of material, including other metals, plastics, composites, and
other man-made materials. Because the barbell collar 100 is
generally used in weight-lifting, it may preferably be made of a
heavy and strong metal, such as steel and/or iron. The first weight
bar 106 and second weight bar 108 may be solid, or substantially
tubular (hollow) (as shown), and are generally configured to
receive and hold various weights, such as barbell disc weights,
which are not shown, but are well known in the art. As shown, the
first weight bar 106 and second weight bar 108 may be located
approximately near the ends of light arm 103 and the heavy arm 104,
respectively, and may be substantially perpendicular to the light
arm 103 and heavy arm 104.
[0047] The barbell engagement portion 150 may be hole, as shown and
may be configured to engage with and secure onto a barbell,
typically an end portion of a barbell. The barbell engagement
portion 150 may also include an axle-bearing (shown in FIGS. 3 and
4), which may be configured to releasably lock the barbell collar
100 into a particular lateral position with respect to the barbell.
In one embodiment the collar 100 may lock onto the barbell such
that the collar 100 does not rotate with respect to the barbell. In
another embodiment, the barbell is configured to freely rotate with
respect to the collar 100. The axel-bearing may lock onto the
barbell and be freely rotatable with the collar 100 or the
axel-bearing may lock onto the collar 100 and be freely rotatable
with the barbell. Although the barbell engagement portion 150 may
be a hole, as shown, the engagement portion 150 may be a notch,
clamp, hook, grip, or the like for engaging with and being lifted
by, a barbell.
[0048] The light arm 102 and heavy arm 104 may be have the same
length (or substantially the same length), as preferred, or may be
of different lengths. Preferably, the light arm 102 may be lighter
than the heavy arm 104. FIG. 1 shows that one way to make the light
arm 102 lighter than heavy arm 104, but still have both arms 102,
104 have the same length is to include a cutout 103 in the light
arm 102. Another way to make the light arm 102 lighter than the
heavy arm 104 is to have notches or holes cut/drilled into the
light arm 102. Another way to make the light arm 102 lighter than
the heavy arm 104 is to construct the lighter arm from lighter or
less dense material, such as aluminum rather than iron, or to make
the light arm physically thinner.
[0049] In one embodiment, the heavy arm 104 is greater in
weight/mass than the light arm 102 by a 5:3 ratio.
[0050] Regarding the position and alignment between the light arm
102 and the heavy arm 104, the light arm portion 102 may be angled
or aligned away from the heavy arm 104 in various degrees. For
example, in an embodiment, the light arm 102 may be angled from the
heavy arm 104 between 91.degree. and 179.degree. degrees, and may
be approximately between 130.degree. and 140.degree. degrees. In a
preferred embodiment, the light arm 102 may be angled or aligned
away from the heavy arm 104 at approximately 135.degree. degrees
(shown in FIG. 2).
[0051] During use, the barbell collar 100 may allow the user to
experience various exercise positions and resistance. This is
generally because the first weight bar 106 and second weight bar
108 are generally configured to freely rotate relative to the end
portion on the barbell. For example, during use of the barbell
collar 100, the user may face towards the concave portion of the
barbell collar 100 (e.g., the 135 degree portion of the barbell
collar 100 in-between the light arm 102 and heavy arm 104) (as
shown in FIG. 3). Alternatively, during use of the barbell collar
100, the user may face the convex portion of the barbell collar 100
(e.g., the 225 degrees portion in-between the first arm portion 107
and second arm portion 108 of the barbell collar 100) (as shown in
FIG. 4). The user may also position the barbell collars in a manner
such that the user may face the concave portion of one barbell
collar while, at the same time, face the convex portion of another
barbell collar. As a result, the user may experience resistance
through the sagittal plane, the coronal plane, the transverse
plane, and the horizontal plane, or any combinations thereof.
[0052] When disc weights are not loaded onto the first weight bar
106 and second weight bar 108 of the barbell collar 100, the arms
102, 104 of the plate 101 may be positioned at various degrees
relative to the barbell. For example, the light arm 102 may be
positioned at an angle of approximately 90.degree. degrees relative
to the barbell's horizontal plane when the barbell and barbell
collar 100 are not in contact with any surface. Additionally, the
heavy arm 104 may be positioned at approximately 45.degree. degrees
relative to the barbell's horizontal plane when the barbell and
barbell collar 100 are not in contact with any surface. However,
various positions may be configured to the light arm 102, heavy arm
104, or combination thereof, thereby influencing the position of
the arm relative to the horizontal plane of the barbell. The manner
in which the barbell may move may also further influence the
position of the arms relative to the horizontal plane of the
barbell. The collar 100, as shown in FIG. 1, may allow the arms
102, 104 of the collar 100 to be positioned in a non-parallel
manner with the horizontal plane in order to influence the
perceived resistance curve of the user.
[0053] In some embodiments, the at least two weight bars 106, 108
may be unitary portions of the plate 101 as shown in FIGS. 11 and
12.
[0054] FIG. 2 is an illustration of a side view of one embodiment
of the barbell collar. As shown in FIG. 2, one embodiment of the
barbell collar 100 may comprise: a plate 101, first weight bar 106,
and second weight bar 108, wherein the plate 101 may comprise: a
barbell engagement portion 150, light arm 102, and heavy arm 104.
FIG. 2 shows that the light arm 102 may be lighter than the heavy
arm 104 (because of cut out portion 103) and may be angled at
approximately 135.degree. degrees from the heavy arm 104. In a
preferred embodiment, the light arm 102 may weigh approximately 3
units as compared to a weight of approximately 5 units for the
heavy arm 104. Thus, the weight of the light arm 102 to the heavy
arm 104 may be a ratio of approximately 3:5.
[0055] FIG. 3 is an illustration of a side view of the barbell
collar on a barbell with the heavy arm configured away from a user.
As shown in FIG. 3, one embodiment of the barbell collar 100 may
comprise: a plate 101, first weight bar 106, and second weight bar
108, wherein the plate 101 may comprise: a barbell engagement
portion 150 (shown in FIGS. 1 and 2), light arm 102, and heavy arm
104. FIG. 3 shows that the light arm 102 may be lighter than the
heavy arm 104 (because of cut out portion 103) and may be angled at
approximately 135.degree. degrees from the heavy arm 104. FIG. 3
shows that the collar 100 is engaged with barbell 200, which is
held at least laterally in place by an axle-bearing 202. FIG. 3
shows that the collar 100 may freely rotate with respect to barbell
200, and, in this configuration, the heavy arm 106, which is away
from the user 300, is hanging lower than the light arm 108 and
angled down, due to being heavier. In one embodiment the bearing
assembly may comprise a clamping ring to secure it to the weight
bar.
[0056] FIG. 4 is an illustration of a side view of the barbell
collar on a barbell with the heavy arm configured close to a user.
As shown in FIG. 4, one embodiment of the barbell collar 100 may
comprise: a plate 101, first weight bar 106, and second weight bar
108, wherein the plate 101 may comprise: a barbell engagement
portion 150 (shown in FIGS. 1 and 2), light arm 102, and heavy arm
104. FIG. 4 shows that the light arm 102 may be lighter than the
heavy arm 104 (because of cut out portion 103) and may be angled at
approximately 135.degree. degrees from the heavy arm 104. FIG. 4
shows that the collar 100 is engaged with barbell 200, which is
held at least laterally in place by an axle-bearing 202. FIG. 4
shows that the collar 100 may freely rotate with respect to barbell
200, and, in this configuration, the heavy arm 106, which is close
to the user 300, is hanging lower than the light arm 108 and angled
down, due to being heavier.
[0057] Depending on whether the user 300 does a curl as shown in
FIG. 3 or FIG. 4, the user 300 will experience a different
perceived resistance curve as compared to each other. The peak of
the resistance curve occurs at a different angle of the movement
when comparing the curl in FIG. 3 or FIG. 4. Further, the actual
shape of the resistance curve (force vs angle) would be different
as well.
[0058] FIG. 5 is an illustration of a side view of another
embodiment of the barbell collar. As shown in FIG. 5, one
embodiment of the barbell collar 500 may comprise: a plate 501,
first weight bar 506, and second weight bar 508, wherein the plate
501 may comprise: a barbell engagement portion 550, light arm 502,
and heavy arm 504. FIG. 3 shows that the light arm 502 may be
lighter than the heavy arm 504 because of a plurality of holes 503
cut or drilled into light arm 502.
[0059] FIG. 6 is an illustration of a side view of another
embodiment of the barbell collar. As shown in FIG. 6, one
embodiment of the barbell collar 600 may comprise: a plate 601,
first weight bar 606, and second weight bar 608, wherein the plate
601 may comprise: a barbell engagement portion 650, light arm 602,
and heavy arm 604. FIG. 3 shows that the light arm 602 may be
lighter than the heavy arm 604 because of one or more notches or
grooves 603 that are on one or both sides of light arm 602.
[0060] FIG. 7 is an illustration of a side view of another
embodiment of the barbell collar. As shown in FIG. 7, one
embodiment of the barbell collar 700 may comprise: a plate 701,
first weight bar 706, and second weight bar 708, wherein the plate
701 may comprise: a barbell engagement portion 750, light arm 702,
and heavy arm 704. FIG. 3 shows that the light arm 702 may be
lighter than the heavy arm 704 because light arm 702 is thinner
and/or has less mass or less material than heavy arm 704.
[0061] FIG. 8 is an illustration of a side view of another
embodiment of the barbell collar. As shown in FIG. 7, one
embodiment of the barbell collar 800 may comprise: a plate 801,
first weight bar 806, and second weight bar 808, wherein the plate
801 may comprise: a barbell engagement portion 850, light arm 802,
and heavy arm 804. FIG. 3 shows that the light arm 802 may be
lighter than the heavy arm 804 because light arm 802 is made from a
material that is lighter than the material of which heavy arm 804
is constructed, or because light arm 802 is made from a less dense
version of the same material of which heavy arm 804 is constructed,
and is thus lighter than heavy arm 804.
[0062] FIG. 9 is an illustration of a side view of the barbell
collar on a barbell with the heavy arm configured away from a user
and showing weights on the weight bars. As shown in FIG. 9, one
embodiment of the barbell collar 100 may comprise: a plate 101,
first weight bar 106, and second weight bar 108, wherein the plate
101 may comprise: a barbell engagement portion 150 (shown in FIGS.
1 and 2), light arm 102, and heavy arm 104. FIG. 9 shows that the
light arm 102 may be lighter than the heavy arm 104 (because of cut
out portion 103) and may be angled at approximately 135.degree.
degrees from the heavy arm 104. FIG. 9 shows that the collar 100 is
engaged with barbell 200, which is held at least laterally in place
by an axle-bearing 202. FIG. 9 shows that the first weight bar 106
may engage one or more weights, in this case a five (5) pound disc
weight 388, and second weight bar 108 may engage one or more
weights, in this case a ten (10) pound disc weight 389. As compared
to the configuration in FIGS. 3 and 10, the heavy arm 108 is now
hanging even lower (because the second weight bar 108 has more
weight on it than the first weight bar 106), which provides the
user with a different lifting experience and force curve.
[0063] FIG. 10 is an illustration of a side view of the barbell
collar on a barbell with the heavy arm configured away from a user
and showing weights on the weight bars. As shown in FIG. 9, one
embodiment of the barbell collar 100 may comprise: a plate 101,
first weight bar 106, and second weight bar 108, wherein the plate
101 may comprise: a barbell engagement portion 150 (shown in FIGS.
1 and 2), light arm 102, and heavy arm 104. FIG. 9 shows that the
light arm 102 may be lighter than the heavy arm 104 (because of cut
out portion 103) and may be angled at approximately 135.degree.
degrees from the heavy arm 104. FIG. 9 shows that the collar 100 is
engaged with barbell 200, which is held at least laterally in place
by an axle-bearing 202. FIG. 9 shows that the first weight bar 106
may engage one or more weights, in this case a five (5) pound disc
weight 388, and second weight bar 108 may engage one or more
weights, in this case a five (5) pound disc weight 390. As compared
to the configurations in FIGS. 3 and 9, this configuration provides
a similar, but heavier lift than FIG. 3. Having at least two weight
bars 106 and 108 allows the user to vary where to place the weights
to vary the type of lift experience and force curve.
[0064] FIG. 11 is an illustration of a top perspective view of
another embodiment of a barbell collar. As shown in FIG. 11, the
barbell collar 1100 may comprise: a barbell engagement portion
1101, a first weight bar 1106, and second weight bar 1108, light
arm 1102, and heavy arm 1104. In this embodiment the light arm 1102
and heavy arm 1104 may be of different lengths, which causes them
to be of different weights. This embodiment is similar to the
embodiments shown in Applicant's U.S. patent application Ser. No.
14/760,333, but in this embodiment, the light arm 102 and heavy arm
104 are of different weights. The embodiments shown in Applicant's
U.S. patent application Ser. No. 14/760,333 are of different
lengths, but may be the same weight or different weights.
[0065] The barbell engagement portion 1101 may comprise a hole
1150, which is configured to engage with a barbell.
[0066] The barbell collar 1100 may be generally constructed of any
rigid material, such as metal (e.g., steel, iron, aluminum), but
may be constructed of any type of material, including other metals,
plastics, composites, and other man-made materials. FIG. 11 shows
that the barbell collar 1100 may be a single unit with different
portions. In other embodiments the collar 1100 may be made from
several units that are permanently connected together via welding,
adhesives, connectors, soldering, ultrasonic welding, and the like.
Because the barbell collar 1100 is generally used in
weight-lifting, it may preferably be made of a heavy and strong
metal, such as steel and/or iron. The first weight bar 1106 and
second weight bar 1108 may be solid, or substantially tubular
(hollow), and are generally configured to receive and hold various
weights, such as barbell disc weights, which are not shown, but are
well known in the art. As shown, the first weight bar 1106 and
second weight bar 1108 may be located approximately near the ends
of light arm 1103 and the heavy arm 1104, respectively, and may be
substantially perpendicular to each other.
[0067] The barbell engagement portion 1101 may be configured to
engage with and secure onto a barbell, typically an end portion of
a barbell, with a second collar attached to the other end of the
barbell. The barbell engagement portion 1101 may also include or
engage with an axle-bearing (shown in FIGS. 3 and 4), which may be
configured to releasably lock the barbell collar 1100 into a
particular lateral position with respect to the barbell. In one
embodiment the collar 1100 may lock onto the barbell such that the
collar 1100 does not rotate with respect to the barbell. In another
embodiment, the barbell is configured to freely rotate with respect
to the collar 1100.
[0068] The light arm 1102 and heavy arm 1104 may be have the same
length (or substantially the same length), as preferred, or may be
of different lengths. Preferably, the light arm 1102 may be lighter
than the heavy arm 1104. FIG. 11 shows that one way to make the
light arm 1102 lighter than heavy arm 1104, is to have the arms
1102, 1104 have different lengths, which means heavy arm 1104 may
have more material mass and is thus, heavier. In one embodiment,
the heavy arm 104 is greater in weight/mass than the light arm 102
by a 5:3 ratio, due to a greater length in a 5:3 ratio.
[0069] Regarding the position and alignment between the light arm
1102 and the heavy arm 1104, the light arm portion 102 may be
angled 1199 or aligned away from the heavy arm 1104 in various
degrees. For example, in an embodiment, the light arm 1102 may be
angled from the heavy arm 1104 between 91.degree. and 179.degree.
degrees, and may be approximately between 130.degree. and
140.degree. degrees. In a preferred embodiment, the light arm 1102
may be angled or aligned away from the heavy arm 1104 at
approximately 135.degree. degrees (shown in FIG. 2).
[0070] During use, the barbell collar 1100 may allow the user to
experience various exercise positions and resistance. This is
generally because the first weight bar 1106 and second weight bar
1108 are generally configured to freely rotate relative to the end
portion on the barbell. For example, during use of the barbell
collar 1100, the user may face towards the concave portion of the
barbell collar 1100 (e.g., the 135 degree portion of the barbell
collar 1100 in-between the light arm 1102 and heavy arm 1104) (as
shown in FIG. 3). Alternatively, during use of the barbell collar
1100, the user may face the convex portion of the barbell collar
1100 (e.g., the 225 degrees portion in-between the first arm
portion 1107 and second arm portion 1108 of the barbell collar
1100) (as shown in FIG. 4). The user may also position the barbell
collars in a manner such that the user may face the concave portion
of one barbell collar while, at the same time, face the convex
portion of another barbell collar. As a result, the user may
experience resistance through the sagittal plane, the coronal
plane, the transverse plane, and the horizontal plane, or any
combinations thereof.
[0071] When disc weights are not loaded onto the first weight bar
1106 and second weight bar 1108 of the barbell collar 1100, the
arms 1102, 1104 of the collar 1100 may be positioned at various
degrees relative to the barbell. For example, the light arm 1102
may be positioned at an angle of approximately 90.degree. degrees
relative to the barbell's horizontal plane when the barbell and
barbell collar 1100 are not in contact with any surface.
Additionally, the heavy arm 1104 may be positioned at approximately
45.degree. degrees relative to the barbell's horizontal plane when
the barbell and barbell collar 1100 are not in contact with any
surface. However, various positions may be configured to the light
arm 1102, heavy arm 1104, or combination thereof, thereby
influencing the position of the arm relative to the horizontal
plane of the barbell. The manner in which the barbell may move may
also further influence the position of the arms relative to the
horizontal plane of the barbell. The collar 1100, as shown in FIG.
11, may allow the arms 1102, 1104 of the collar 1100 to be
positioned in a non-parallel manner with the horizontal plane in
order to influence the perceived resistance curve of the user.
[0072] FIG. 12 is an illustration of a top perspective view of
another embodiment of a barbell collar. As shown in FIG. 12, the
barbell collar 1200 may comprise: a barbell engagement portion
1201, a first weight bar 1206, and second weight bar 1208, light
arm 1202, and heavy arm 1204. In this embodiment the light arm 1202
and heavy arm 1204 may be of different diameters, which causes them
to be of different weights. Heavy arm 1204, as shown, may be
thicker and thus greater in diameter than the light arm 1202, which
causes the heavy arm 1204 to be greater in mass or weight. Although
the arms 1202, 1204 are shown having the same length, they do not
have to be of the same or substantially the same length. In some
embodiments the arms 1202, 1204 are different lengths, as shown in
FIG. 12. The barbell engagement portion 1201 may comprise a hole
1250, which is configured to engage with a barbell.
[0073] FIG. 13 is an illustration of a top plan view of an
embodiment of a fixed resistance component having different arms
lengths and similar weight components. As shown in FIG. 13, the
fixed resistance component 1300 may comprise a plate 1305, hole
1310, first arm 1315, second arm 1320, first weight component 1325,
and second weight component 1330. The plate 1305 may comprise a
structural component to which the other components of the fixed
resistance component may be affixed or related to. In one
embodiment, the weight components 1325, 1330 may slidably (and
removeably) engage the arms 1315, 1320. In alternative embodiments,
the weight components 1325, 1330 may be permanently attached to the
arms 1315, 1316. In another alternative embodiment, the weight
components 1325, 1330 may removeably engage the arms 1315, 1320, in
some other manner.
[0074] The first arm 1315 may be longer than the second arm 1320.
As shown, the first arm 1315 and second arm 1320 may be at an angle
relative to one another. This angle between the first and second
arms 1315, 1320 may be anywhere between 0 and 180 degrees, and more
preferably, in the range between 130 and 140 degrees. In one
embodiment, the first and second arms 1315, 1320 are at an angle of
135 degrees relative to one another. The first weight component
1325 and second weight component 1330 may be substantially similar
in weight.
[0075] As shown, the hole 1310 may have one or more notches or be
ring gear shaped. In alternative embodiments, the hole 1310 may be
substantially any shape configured to matingly receive a structure
having a fixing shape, such that when the hole 1310 receives the
structure having a fixing shape, the hole 1310 and structure having
a fixing shape are rotationally locked relative to one another and
are not freely rotatable. In one embodiment, the hole 1310 and
fixing shape may be substantially gear-shaped, which may allow the
hole 1310 to engage the fixing shape in a variety of
configurations, such that multiple fixed resistance components 1300
may each engage the structure having a fixing shape at different
rotational configurations.
[0076] In alternative embodiments, the hole 1310 may be configured
to engage barbell collars (or ends), thereby fixing the fixed
resistance component relative to the barbell collars.
[0077] In alternative embodiments, the hole 1310 may be configured
to engage fixed resistance components having a structure that has a
fixing shape.
[0078] The fixed resistance component 1300 may be made from a
durable material, such as steel, iron, aluminum, or some other
metal alloy.
[0079] FIG. 14 is an illustration of a top plan view of an
embodiment of a fixed resistance component having different arms
lengths and different weight components. As shown in FIG. 14, the
fixed resistance component 1400 may comprise a plate 1405, hole
1410, first arm 1415, second arm 1420, first weight component 1425,
and second weight component 1430. The fixed resistance component
1400 shown in FIG. 14 may be substantially similar to the fixed
resistance component 1300 shown in FIG. 13, except that the first
and second weight components 1425, 1430 may be different, such that
the first weight component 1425 is lighter than the second weight
component 1430 and located on the first arm 1415.
[0080] FIG. 15 is an illustration of a top plan view of an
embodiment of a fixed resistance component having different arms
lengths and different weight components. As shown in FIG. 15, the
fixed resistance component 1500 may comprise a plate 1505, hole
1510, first arm 1515, second arm 1520, first weight component 1525,
and second weight component 1530. The fixed resistance component
1500 shown in FIG. 15 may be substantially similar to the fixed
resistance component 1300 shown in FIG. 13, except that the first
and second weight components 1425, 1430 may be different, such that
the first weight component 1425 is heavier than the second weight
component 1430 and located on the first arm 1415.
[0081] FIG. 16 is an illustration of a top plan view of an
embodiment of a fixed resistance component having a single arm. As
shown in FIG. 16, the fixed resistance component 1600 may comprise
a plate 1605, hole 1610, arm 1615, and weight component 1625, and
second weight component 1630. The fixed resistance component 1600
shown in FIG. 16 may be substantially similar to the fixed
resistance component 1300 shown in FIG. 13, except that the fixed
resistance component 1600 comprises only one arm 1615 and one
weight component 1625.
[0082] FIG. 17a is an illustration of a top plan view of an
embodiment of a fixed resistance component having different arms
lengths and no weight components. As shown in FIG. 17, the fixed
resistance component 1700 may comprise a plate 1705, hole 1710,
first arm 1715, and second arm 120. The fixed resistance component
1700 shown in FIG. 17 may be substantially similar to the fixed
resistance component 1300 shown in FIG. 13, except that the fixed
resistance component 1700 does not have weight components attached.
Additionally, as shown in FIG. 17, the fixed resistance component
1700 comprises a first weight connection point 1725 and a second
weight connection point 1730. In one embodiment, weight components
may slidable engage the weight connection points 1725, 1730. In
alternative embodiments, weight components may engage the weight
connection points 1725, 1730 by substantially any releasably
engaging mechanism.
[0083] FIG. 17b is an illustration of a perspective view of an
embodiment of a removeable weight. FIG. 17b shows that first weight
connection point 1725 is configured to engage with weight component
1726 at weight slot 1727. Preferably, the weight component 1726 may
releasably lock into place with weight connection point 1725.
[0084] FIG. 18 is an illustration of an embodiment of a barbell
showing a fixing shape portion. As shown in FIG. 18, the barbell
1800 may comprise a bar 1805, and an end 1810, which may comprise a
collar 1811 and a fixing shape portion 1815. The fixing shape
portion 1815 may extend longitudinally and be configured to
matingly engage one or more of the fixed resistance components
shown in FIGS. 13-17. Because the fixing shape portion 1815 may be
ring gear shaped, as shown, multiple fixed resistance components,
which may be gear shaped, may engage the barbell 1800 at angles
independent of one another. The collar 1811 may prevent the fixed
resistance components from further sliding proximally to the center
of the bar 1805.
[0085] In some embodiments, the fixing shape portion 1815 may be
static or fixed with respect to bar 1805, which is preferably a
barbell. In other embodiments, the fixing shape portion 1815 may
freely rotate with respect to bar 1805. In some embodiments, the
fixing shape portion 1815 may rotate on ball bearings round shaft
1816. When the fixing shape portion 1815 is rotatable with respect
to bar 1805, the fixing shape portion 1815 will rotate based on the
configurations of the fixed resistance components finding an
equilibrium.
[0086] FIG. 19 is an illustration of a side view of an embodiment
of a barbell and multiple fixed resistance components. As shown in
FIG. 19, a barbell with fixed resistance components 1900 may have a
structure having a fixing shape, shown as fixing shape portion
1920, which may matingly engage with the ring gear shaped holes of
fixed resistance components 1905, 1910, 1911, including ring gear
shaped hole 1925 of fixed resistance component 1915. In this
manner, the one or more fixed resistance components 1905, 1910,
1915 may each engage the barbell at positions different from one
another. This allows the user to add weight to the barbell 2030 in
hundreds of different configurations. When you combine the hundreds
of different weight configurations with (1) the fixed resistance
components themselves may have different configurations, (2) even,
uneven, or no weights, (3) one, two, three, or more arms, and (4)
the varying angles between the arms, the weight system of the
present disclosure has essentially an infinite amount of
configurations. This allows the user to determine an optimal
resistance curve for exercising with a maximum desired benefit.
[0087] Other configurations include: [0088] a single fixed
resistant component on one side of the barbell; [0089] a single
fixed resistant component with one arm and one weight; [0090] a
single fixed resistant component with two arms, but only one has a
weight; [0091] a single fixed resistant component with two arms,
and both have a weight; [0092] a single fixed resistant component
with two arms, and both have a weight, but the weights are of
unequal weight; [0093] a single fixed resistant component with two
arms, wherein the two arms are of different lengths; [0094] a
single fixed resistant component with three or more arms; [0095]
two fixed resistant components stacked on one side of the barbell
at the same radial configuration; [0096] two fixed resistant
components stacked on one side of the barbell at different radial
configurations; [0097] three or more fixed resistant components
stacked on one side of the barbell at the same or different radial
configurations; [0098] loading both sides of the barbell each with
the same number of fixed resistant components or a different number
of fixed resistant components; [0099] loading both sides of the
barbell with the same number of fixed resistant components in
mirror images of each other; and [0100] loading both sides of the
barbell with the same number of fixed resistant components, but in
different configurations from the opposite side.
[0101] Each of the above configurations and the almost infinite
specific configurations that they can be expressed in may produce
an effect on the perceived resistance curve.
[0102] FIG. 20 is an illustration of a perspective view of an
embodiment of a barbell and multiple fixed resistance components
shown in FIG. 19. As shown in FIG. 19, the barbell with fixed
resistance components 1900 shown in FIG. 19 may comprise a barbell
2030. Also, the structure having a fixing shape, fixing shape
portion 1920, may have a length that allows the ring gear shaped
holes 1925 of one or more fixed resistance components to engage the
structure having a fixing shape, shown here as fixing shape portion
1920. FIG. 20 shows how collar 1911 allows the fixed resistance
components 1905, 1910, 1915 to be stacked onto fixing shape portion
1920. A locking component may be used to lock the fixed resistance
components 1905, 1910, 1915 in place so that they do not
inadvertently slide off the end of fixing shape portion 1920. The
barbell 2030 may have main shaft 2031, which is preferably static
and non-rotatable relative to said fixing shape portions. In one
embodiment, the fixing shape portion 1920 may be the barbell collar
shape.
[0103] FIG. 21 is an illustration of a perspective view of an
embodiment of a barbell and multiple fixed resistance components.
As shown in FIG. 21, the barbell 2030 may have two ends 2110, 2115,
which may have a structure having a fixing shape matingly engaged
to one or more fixed resistance components. As shown in FIG. 21,
each end 2110, 2115 may have three fixed resistance components that
are configured to be mirror images of the other end. In other
embodiments, the user may add the fixed resistance components in an
uneven manner to the two ends 2110, 2115. Preferably, each of the
two ends 2110, 2115 have a fixing shape portion.
[0104] FIG. 21 also shows one embodiment of a system that has a
barbell and at least two weights that are located at opposite ends
of the barbell. The at least two weights are configured to rotate
freely around the barbell. Preferably, when the barbell is
subjected to an arc path of movement during an exercise, said at
least two weights undergo rotational motion, which produces a
rotational inertial torque vector through an axis of rotation,
which results in a user having to compensate for this during the
exercise. The weights may undergo rotational motion via many
different ways, including, but not limited to: an external force
being applied by a pulley, string, or small motor; having weight
plates with mass inserts to alter the mass distribution; and/or
other asymmetric weight plate designs.
[0105] FIG. 22a and FIG. 22b are illustrations of a perspective
view of a barbell showing one of the fixed resistance components
being removed. FIG. 22a shows the barbell 2030 with fixed
resistance components 1905, 1910 stacked in the same position side
by side on fixing shape portion 1920, and fixed resistance
component 1915 stacked in a different configuration on fixing shape
portion 1920. FIG. 22b shows that when fixed resistance component
1915 is removed 2210, the barbell 2020 rebalances 2215, 2225. The
rotational forces of the rebalancing 2215, 2225 is not significant,
which makes the system safer to load and unload the fixed
resistance components.
[0106] FIG. 23A is an illustration of a side view of a traditional
barbell. FIG. 23B and FIG. 23C are illustrations of side view of a
user using a barbell having a fixing shape portion rotatable
relative to the barbell. FIG. 23A depicts a standard barbell and
weight 2300, with the broken line indicating the path of travel of
the barbell. As shown in FIG. 23B, a barbell having a fixing shape
portion rotatable relative to the barbell and a fixed resistance
component having a short arm with a heavy weight positioned toward
a user 2307 and a longer arm with a light weight positioned away
from the user 2307 results in a lowered position 2305 to a raised
position 2310 may result in a rotation or oscillation of the fixed
resistance component, such that the user 2307 is required to
compensate for the motion when moving the barbell from a lowered
position 2305 to a raised position 2310.
[0107] As shown in FIG. 23C, a barbell having a fixing shape
portion rotatable relative to the barbell and a fixed resistance
component having a short arm with a heavy weight positioned away
from a user 2317 and a longer arm with a light weight positioned
toward the user 2317 results in a lowered position 2315 to a raised
position 2320 may result in a rotation or oscillation of the fixed
resistance component, such that the user 2317 is required to
compensate for the motion when moving the barbell from a lowered
position 2315 to a raised position 2320.
[0108] FIG. 24 is an illustration of a perspective view of a
barbell having a fixing shape portion rotatable relative to the
barbell. As shown in FIG. 24, as a barbell 2400 having a fixing
shape that is rotatable relative to the barbell is raised from a
lowered position to a raised position, the fixed resistance
component 2405 may effectively rotate, thereby exerting a torque
vector for which the user would need to compensate.
[0109] FIG. 25 is an illustration of side view of a barbell having
a weight that may rotate around the barbell and one embodiment of a
spinning mechanism. Preferably, the barbell has weights on either
end of it to balance the load. FIG. 25 shows that the weight 2502
may rotate 2506, 2508 around barbell end 2504. The resistance bands
2510, 2512 may be attached (removeably or permanently) to the
weight 2502, such that when barbell is subjected to an arc path of
movement 2550 during an exercise, the weight 2502 undergo
rotational motion caused by the resistance bands 2510, 2512. In
some embodiments only one of the bands 2510, 2512 is used. In the
embodiment shown in FIG. 25, the weight 2502 may or may not having
a fixing shape portion rotatable relative to the barbell end 2504.
In some embodiments, the barbell has two ends and one weight, which
is positioned in the middle, between the arms of the user. When the
user does a curl, or other type of exercise, the pully may get the
weight spinning as it is lifted, which causes a rotational torque
that must be compensated for. This makes the exercise harder, or at
least different, and the exerciser gets more of a benefit.
[0110] FIG. 26 is an illustration of side view of a barbell having
a weight that may rotate around the barbell and another embodiment
of a spinning mechanism. Preferably, the barbell has weights on
either end of it to balance the load. FIG. 26 shows another way
that the weight may be rotated. In this embodiment, the weight 2602
has weighted portions 2603, which may be permanent or removable.
The weighted portions 2603 are preferably heavier, proportionally,
than the material that makes up weight 2602. The weighted portions
2603, when present or removed, preferably cause the weight 2602 to
be offset, such that when a user lifts the barbell in an arc path
2650 during an exercise, the weight 2602 undergoes rotational
motion 2610, 2612 (around barbell end 2604), which produces a
rotational inertial torque vector through an axis of rotation,
which results in a user having to compensate for this during the
exercise. In the embodiment shown in FIG. 25, the weight 2502 may
or may not having a fixing shape portion rotatable relative to the
barbell end 2504.
[0111] FIG. 27 is an illustration of side view of a barbell having
a weight that may rotate around the barbell and another embodiment
of a spinning mechanism. Preferably, the barbell has weights on
either end of it to balance the load. In the embodiment shown in
FIG. 27, rather than having two clearly discernable arms on the
weight 2700, which may or may not be a fixed resistance component,
may comprise a plate, 2702, hole 2710, first arm 2712, and second
arm 2713, which are all embodied in a unitary offset shape.
Although weight 2700 is triangular, any shape may be used. Rather
than having removeable weight portions, the weight portions are
integrated into first arm 2712 and second arm 2713. As an offset
weight, the weight 2700 is configured to rotate 2740, 2741 around
the barbell. Preferably, when the barbell is subjected to an arc
path of movement 2799 during an exercise, the weight 2700 undergoes
rotational motion, which produces a rotational inertial torque
vector through an axis of rotation, which results in a user having
to compensate for this during the exercise.
[0112] Because in one embodiment the fixed resistance components,
once engaged with the barbell, are static and not freely rotatable
around the barbell, the center of gravity may be moved from a
center point of the barbell, to a position that in front or behind
the barbell. Since the center of mass must be at the pivot point,
which is necessarily on the barbell when gripped by the user, the
system allows the user to vary the resistance curve encountered by
the user by varying where the center of gravity is. In an
alternative embodiment, the fixed resistance components may be
fixed only relative to the fixing shape portion, and the fixing
shape portion may be freely rotable about the axis of the
barbell.
