Description
FIELD OF THE INVENTION
[0001] The present invention relates generally to exercise
equipment, and relates more particularly to weight training
equipment.
BACKGROUND OF THE INVENTION
[0002] Exercise devices, and in particular weight training
machines, typically include a mechanical member that the user
repeatedly moves along a prescribed path for exercise.
Conventionally, movement of the mechanical member is resisted in
some fashion (often by weights) to render the movement more
difficult and thereby intensify the exercise. The movement of the
mechanical member determines what muscle or muscle groups are to be
involved in the exercise.
[0003] One exercise device that has become prevalent in recent
years is the multi-functional exercise machine, which enables the
user to position components of the machine in different locations
in order to perform different exercises. These machines have proven
to be particularly popular for serious exercisers and for
exercisers that work with personal trainers, as the machines can be
adjusted to provide the exerciser with numerous exercises that work
different muscle groups. One example of such a machine is
illustrated in International Publication No. WO 01/66195 A2 to
Sechrist et al. (hereinafter "the Sechrist publication"). This
machine includes two arms that extend from a frame generally in the
same direction. The arms are able to pivot approximately 180
degrees about a horizontal axis (termed "rotation" in the Sechrist
publication) to different locked positions (separated by 20 degree
increments), such that their ends are very close together at the
top and bottom of their arcs (when the arms are generally vertical)
and are widely spread when the arms are in the middle of their arcs
(when the arms are essentially horizontal). The arms are also
pivotable to three positions separated by 15 degrees about another
horizontal axis (termed "reach" in the Sechrist publication) that
is normal to the first pivot axis. Cables extend through the arms
and to a weight stack that resides within the frame. Handles are
attached to the cables at the ends of the arms. To exercise, the
exerciser selects positions for each arm (which may differ), then
positions himself in a position, posture and orientation and begins
pulling on one or both of the handles with his hands or feet. The
handles separate from the arms, with resistance being provided by
the weights through the cables.
[0004] One of the reasons machines like that described in the
Sechrist publication are popular is that the exerciser can perform
a large number of exercises with the same machine simply by varying
his position, posture and/or orientation and by varying the
positions of the arms. For example, for any position of the arms,
during exercise the exerciser may choose to face toward or away
from the frame, or may stand sideways relative to the frame; any of
these positions would exercise different muscles or portions
thereof. Similarly, the exerciser may stand, sit, kneel, or lie on
the ground (prone, supine, or on his side), or lie on a bench and
achieve different results. The exerciser may also choose to work
with one or both hands, or with one or both feet, engaging the
handles. Similar variability in exercise can be achieved with
alternative positions of the exercise arms.
[0005] A shortcoming of the machine described in the Sechrist
publication is that the machine has limitations on the positions
its arms can take. More specifically, when the arms are more
vertically oriented, the ends of the arms can be positioned
relatively close to one another; however, when the arms are
generally vertically oriented, the ends of the arms can only move
to within about 72 inches of each other. As a result, the machine
is not suitable for exercises that require the ends of the arms to
be relatively close together and at about waist height for the
exerciser (such as a typical rowing movement).
SUMMARY OF THE INVENTION
[0006] The present invention is directed to a multi-functional
exercise machine that provides, inter alia, arms that can be
positioned adjacent to one another irrespective of their height.
The exercise machine comprises a frame, a pair of arm assemblies, a
pair of handle units, a coupling unit, and a resistance-imparting
unit. Each of the arm assemblies has: an arm having a proximal and
a distal end; and a mounting unit connected with the frame and the
proximal end of the arm. The mounting units are configured such
that the arm is free to pivot relative to the frame about a first
generally vertical axis and about a second generally horizontal
axis, the movement about the first axis being over a range of at
least 50 degrees. The handle units are associated with a respective
one of the distal ends of the arms and are moveable away from that
distal end. The coupling unit is attached to each of the pair of
handle units. The resistance-imparting unit is attached to the
coupling unit and resists movement of the handle units away from
the distal ends of the arms. In this configuration, the arms may be
positioned in inwardmost positions such that their distal ends are
no more than about 10 inches of each other, even when the arms are
generally horizontally disposed; consequently, a full range of
exercise movements can be performed.
[0007] In some embodiments, each of the mounting units includes a
generally horizontally-oriented plate with a series of apertures,
the series of apertures defining preselected locking positions to
which the arm may move about the first axis, and a generally
vertically-oriented plate with a series of apertures, the series of
apertures defining preselected locking positions to which the arm
may move about the second axis. Ordinarily, the apertures are
spaced at circumferentially equal increments.
[0008] As another aspect of the invention, the exercise machine
described above may include a handle bracket rotatably attached to
the distal end of each arm. Each of these handle brackets may
include two pulleys through which a cable attached to the
resistance-imparting unit (typically a weight stack) travels. In
this configuration, the resultant ease of grasping the handle units
may facilitate exercise movements.

DETAILED DESCRIPTION OF THE INVENTION
[0020] The present invention will now be described more fully
hereinafter, in which preferred embodiments of the invention are
shown. This invention may, however, be embodied in different forms
and should not be construed as limited to the embodiments set forth
herein. Rather, these embodiments are provided so that this
disclosure will be thorough and complete, and will fully convey the
scope of the invention to those skilled in the art. In the
drawings, like numbers refer to like elements throughout.
Thicknesses and dimensions of some components may be exaggerated
for clarity.
[0021] Referring now to the drawings, an exercise machine,
designated broadly at 20, is illustrated in FIG. 1. The exercise
machine 20 includes a frame 22, a pair of arm assemblies 60a, 60b,
a pair of handle units 110a, 110b, a coupling unit 120, and a
weight stack 40. These components are described in greater detail
below.
[0022] In describing the exercise machine 20, it will be assumed
for the purposes of description that the terms "front", "forward",
and derivatives thereof refer to the horizontal direction the arm
assemblies 60a, 60b extend away from the frame 22 (i.e., to the
left as shown in FIG. 4). The term "rear" and derivatives thereof
refer to the horizontal direction that is opposite the "forward"
direction (i.e., to the right as shown in FIG. 4). Together, the
"forward" and "rear" directions comprise the "longitudinal"
dimension of the machine 20. The terms "outward", "outer" and
derivatives thereof refer to the horizontal direction defined by a
vector beginning at the center of the machine 20 and extending
perpendicularly to the longitudinal dimension; conversely, the
terms "inner", "inward" and derivatives thereof refer to the
horizontal direction opposite the "outward" direction. Together,
the "inward" and "outward" directions comprise the "transverse"
dimension of the machine 20.
[0023] Referring again to FIG. 1, the frame 22 includes two
longitudinally-extending base members 24 that rest on the
underlying surface, and a lower cross-member 26 that spans the
distance between the base members 24. An arch 28 is mounted to and
rises from the base members 24. The arch 28 has two generally
upright sections 28a, 28b and a spanning section 28c that extends
between the upper ends of the upright sections 28a, 28b. Each of
two lower arm supports 30a, 30b extends inwardly from a central
portion of a respective arch upright section 28a, 28b and each of
two upper arm supports 32a, 32b extends inwardly from an upper
portion of a respective arch upright section 28a, 28b.
[0024] Those skilled in this art will recognize that the frame 22
illustrated herein is exemplary and can take many configurations
that would be suitable for use with the present invention. The
frame 22 provides a strong, rigid foundation to which other
components can be attached at desired locations, and other frame
forms able to serve this purpose may also be acceptable for use
with this invention.
[0025] Referring again to FIG. 1 and also to FIGS. 9 and 10, the
weight stack 40 includes a set of weights 44 arranged in a vertical
stack that rests upon the cross-member 26. A lifting rod 48 extends
vertically through apertures in the weights 44 and is configured to
receive a pin 46 inserted between individual weights 44 that
enables the user to select the number of weights to be used in the
exercise. The weight stack 40 also includes guide rods 42a, 42b
that extend vertically from the cross-member 26 through the weights
44 and to the spanning section 28c of the arch 28. The guide rods
42a, 42b guide the weights 44 along a vertical path during
exercise. Weight stacks of this variety are well known to those
skilled in this art and need not be described in detailed herein.
In addition, the machine 20 may optionally include a set of
auxiliary weights (not shown) that slide along a vertical guide rod
and that can be temporarily connected with the selected weights to
provide incremental weight during exercise. Again, auxiliary weight
systems of this type are well known to those skilled in this art
and need not be described in detail herein. An exemplary machine
having such a weight stack is a leg extension machine available
from Nautilus HPS, Inc. (Independence, Va.) under the trade name
NITRO.TM..
[0026] Those skilled in this art will recognize that, although a
weight stack is the preferred structure for providing resistance to
the exerciser, other resistance-imparting structures, such as
friction-imparting devices, variable viscosity devices, air
drag-based resistance devices, and the like, may also be employed
with an exercise machine of the present invention. Exemplary
resistance devices include those illustrated in U.S. Pat. Nos.
5,810,096, 4,708,338; 4,720,093; 5,033,733; 4,542,897; 4,298,893;
4,805,901; 4,790,528; 4,786,049; 5,031,900; 4,775,145;
4,589,656;and 4,659,074, the disclosures of each of which are
hereby incorporated herein by reference in their entireties.
[0027] The arm assemblies 60a, 60b are essentially mirror images of
one another about a vertical plane P (see FIG. 7) that extends
longitudinally through the center of the frame 22. In the interest
of clarity and brevity, only one arm assembly 60a will be described
in detail herein; those skilled in this art will appreciate that
this discussion is equally applicable to the arm assembly 60b.
[0028] Referring now to FIGS. 1, 2, 3A and 3B, the arm assembly 60a
is attached to the frame 22 via a mounting bracket 62. The mounting
bracket 62 is mounted at its upper and lower ends to the upper and
lower supports 30a, 32a and is free to rotate relative thereto
about a vertical axis of rotation A1. The mounting bracket 62
includes a short inner panel 64, a rear panel 66 merging with and
extending laterally from the rear edge of the inner panel 64, and
an outer panel 68 merging with and extending generally forwardly
from the outer edge of the rear panel 66, such that a generally
U-shaped channel is formed. The outer panel 68 is generally
semicircular in shape and includes near its perimeter a series of
position apertures 70 arranged in a semicircle at circumferential
increments of, in this embodiment, about 15 degrees, although other
increments may also be suitable. A pulley 69a is rotatably mounted
to the upper ends of the inner panel 64 and outer panel 68.
[0029] Referring again to FIGS. 1,2, 3A and 3B, a
horizontally-disposed, generally semicircular upper position plate
82 is fixed to the upper end of the mounting bracket 62. The upper
position plate 82 includes a series of apertures 84 arranged in a
semicircle about its forward perimeter edge at circumferential
increments of about 15 degrees; the center of the semicircle
defined by the apertures 84 is coincident with the axis A1. Other
circumferential increments may also be suitable for us with this
invention. A locking handle 86 is mounted to the upper arm support
32a and is operatively connected with a pin 88 sized and positioned
to extend through a selected one of the apertures 84. Thus,
insertion of the pin 88 into one of the apertures 84 prevents
rotation of the mounting bracket 62 about the axis A1.
[0030] Referring now to FIGS. 1 and 2, the arm assembly 60a also
includes a pulley support 72 comprising a pair of opposed plates
72a, 72b, between which is rotatably mounted a pulley 80. The
pulley support 72 is pivotally attached at its rear end between the
inner panel 64 and the outer panel 68 of the mounting bracket 62 at
a pivot 73, such that the pulley support 72 is pivotable about a
horizontal axis A2 (note that the axis A2 is coincident with the
center of the semicircle defined by the apertures 70 located on the
mounting bracket 62). A handle 76 is mounted on the plate 72a and
is operably connected to a pin 78 (see FIGS. 4-6) that extends
through apertures 74 in the plates 72a, 72b. The pin 78 is sized
and configured such that it can be received in one of the position
apertures 70. Insertion of the pin 78 into one of the position
apertures 70 prevents rotation of the pulley support 72 about the
axis A2.
[0031] Those skilled in this art will recognize that other
configurations may provide a mounting unit suitable for rotatably
mounting the arm assembly 60a to the frame 22. For example, the
generally vertical arrangement of the mounting bracket 62 may be
changed to a transverse horizontal disposition, such that it
rotates relative to the frame about a horizontal axis, and the
pulley support rotates relative to the mounting bracket about a
vertical axis. In addition, although the pin and aperture
configuration described herein is preferred, other mechanisms for
selecting desired positions of the mounting bracket relative to the
frame and the pulley support relative to the mounting bracket may
also be employed. For example, a series of detents rather than
apertures may be used, or the mounting bracket and pulley support
may be retained in position through the tightening of a clamp,
bolt, or other fastener. Those skilled in this art will recognize
other configurations that may be employed.
[0032] Referring now to FIG. 1, the arm assembly 60a further
includes an arm 90, which is fixed at its proximal end 91 to the
front end of the pulley support 72. In the illustrated embodiment,
the arm 90 is tubular and hollow and extends forwardly away from
the pulley support 72. At its distal end 93, the arm 90 has a
finger 96 that is smaller than the remainder of the arm 90. A fin
92 extends downwardly from an intermediate portion of the arm 90. A
pneumatic cylinder unit 94 is attached at one end to the fin 92 and
at its opposite end to the lower portion of the mounting bracket
outer plate 68. Preferably, the arm 90 is between about 24 and 60
inches in length, and is mounted between about 30 and 60 inches
from the underlying surface.
[0033] The ordinarily skilled artisan will recognize that other
configurations for the arm 90 may also be employed. For example,
the arm may not be hollow, but instead may be an open channel, or
even a solid member that includes structure to allow the passage of
a cable 118 (see description of the cable below). Also, the arm 90
and pulley support 72 may be formed as an integral unit, such that
the arm 90 attaches directly to the mounting bracket 62 (if this
configuration is employed, the discussion above regarding the
interaction between the pulley support and the mounting bracket
would apply to the arm itself).
[0034] Referring still to FIG. 1, and also to FIGS. 4-8, the arm
assembly 60a also includes a handle pulley assembly 100, which is
rotatably mounted to the finger 96 of the arm 90 such that it is
free to rotate relative to the arm 90 about an axis A3 that is
parallel with the longitudinal axis of the arm 90 (ie., the axis
extending between the proximal and distal ends 91, 93 of the arm
90). The handle pulley assembly 100 includes opposed side walls
102a, 102b that are fixed to a sleeve 104 (see FIGS. 7 and 8 for
views of the side walls 102a, 102b). The sleeve 104 is mounted over
the finger 96 and is rotatable relative thereto. Two pulleys 106,
108 are rotatably mounted between the side walls 102a, 102b in
locations that permit the passage of the cable 118 therebetween.
The pulleys 106, 108 are distally offset from one another, with the
pulley 106 being positioned between about 0 and 3 inches closer to
the sleeve 104 than the pulley 108.
[0035] Referring now to FIGS. 1 and 4-6, the handle unit 110a will
be described, with the understanding that the description is
equally applicable to the handle unit 110b. The handle unit 110a is
positioned forwardly of the handle pulley assembly 100. The handle
unit 110a includes a handle 112, a flexible strap 114 attached to
each end of the handle 112 and formed into a loop, and a ring 116
that is fitted over the strap 114 and attached to the end of the
aforementioned cable 118. The ring 116 is configured to abut the
handle pulley assembly side walls 102a, 102b; the strap 114 and the
handle 112 depend from the ring 116 and dangle therefrom until
grasped by an exerciser.
[0036] Referring now to FIGS. 1 and 9, the coupling unit 120, which
includes the cable 118, couples both of the handle units 110a, 110b
with the weight stack 40. The cable 118 extends from the handle
unit 110a, through one of the handle pulley assemblies 100 (passing
between the pulleys 106, 108), through one of the arms 90, through
a series of pulleys that comprise a pulley train 121 (described in
detail below), through the other arm 90, through the other handle
pulley assembly 110 (again passing through the pulleys 106, 108
thereof), and to the other handle unit 110b. Thus, a single cable
118 couples both of the handles 112 with the weight stack 40. The
details of the pulley train configuration are set forth below.
[0037] The pulley train 121 includes the left and right pulleys
69a, 69b that are attached to their respective mounting brackets 62
of the arm assemblies 60a, 60b, left and right pulleys 122a, 122b
that are rotatably mounted to the frame 22 near the ends of the
spanning section 28c of the arch 28, left and right transitional
pulleys 124a, 124b mounted near the center of the spanning section
28c, left and right weight stack pulleys 126a, 126b mounted to the
uppermost weight 44, and a single central pulley 128 mounted to the
frame 22 below the left and right transitional pulleys 124a, 124b.
The cable 118 serially engages the pulleys serially in the
following manner. The cable 118 extends from the left handle unit
110a through the handle pulley assembly 100 (engaging the pulleys
106, 108) and the arm 90, then engages the pulley 69a and travels
upwardly. It then passes over and engages the left pulley 122a,
travels inwardly to pass over and engage the left transitional
pulley 124a, and travels downwardly to the left weight pulley 126a.
The cable 118 engages and passes below the left weight pulley 126a
and travels upwardly to the central pulley 128. The cable 118 then
passes over the central pulley 128 and travels downwardly to pass
below and engage the right weight pulley 126b. The cable 118 then
travels upwardly to the right transitional pulley 124b, outwardly
to the right pulley 122a, downwardly to the pulley 69b of the arm
assembly 60b, and out the arm 90 to the handle unit 110b.
[0038] Those skilled in this art will appreciate that other units
that couple the handle units 110a, 110b and the weight stack 40 (or
other resistance-imparting unit) may also be employed with the
present invention. For example, the cable 118 may be replaced with
a belt, chain or other flexible member. Also, the pulley train
arrangement may be varied, with the understanding that any
variation should arrange the pulleys such that tension in the cable
caused by exercise meets resistance (in the case of a weight stack,
tension in the cable causes the selected weights to rise). Further,
some or all of the pulleys themselves may be replaced with other
components, (cams, diverting brackets, or the like) that can engage
and redirect the cable as desired.
[0039] The exercise machine 20 can be adjusted to many different
positions for exercise as desired by the exerciser. More
specifically, the arms 90 can be pivoted about the axes A1 and A2
to different positions that the exerciser chooses for a particular
exercise movement. Referring now to FIGS. 3A and 3B, to move either
arm 90 about the axes A1, the exerciser manipulates the locking
handle 86 to remove the pin 88 from the apertures 84. With the pin
88 disengaged from the apertures 84, the mounting bracket 62 (and,
in turn, the arm assembly 60a) is free to rotate about the axis A1
over an arc of approximately 75 degrees and locked into one of a
series of preselected positions based on increments defined by the
apertures 88. Notably, each of the arms 90 is free to move about
this arc irrespective of its position on axis A2. Preferably, the
arms 90 are sized and the apertures 88 are located on the upper
position plate 82 so that the handle units 110a, 110b can, in their
inwardmost positions, be positioned no more than about 10 inches of
each other (preferably no more than 5 inches) when both extend
forwardly of the frame 22, whether the arms 90 are raised, lowered,
horizontally disposed, or at any position in between. It is
preferred that the mounting bracket 62 be configured such that the
arms can move about the axis A1 over a range of at least 50
degrees, and more preferably at least 80 degrees.
[0040] Referring now to FIG. 2, to move either arm 90 about the
axis A2, the exerciser removes the pin 78 from any positioning
aperture 70 in which it resides by manipulating the handle 76. With
the pin 78 removed, the pulley support 72 (and, in turn, the arm
90) is free to pivot about the axis A2 over an arc of approximately
150 degrees (preferably at least 135 degrees) and locked into one
of a series of preselected positions based on the circumferential
increments defined by the apertures 70. As with movement of the arm
90 about the axis A1, movement about the axis A2 is not dependent
on the position of the arm 90 along the axis A1. Once the arm 90
has been moved to the desired position, the pin 78 is released into
the aperture 70 that corresponds to that position.
[0041] The arm assemblies 60a, 60b can be rather heavy; as such,
the gas cylinder units 94 are included to provide resistance to
downward movement of the arm assembly 60a, 60b. As can be
understood by those skilled in this art, the gas cylinder units 94
retract as the arm assemblies 60a, 60b are lowered and extend as
the arm assemblies 60a, 60b are raised.
[0042] The ability of the arms 90 to move into positions
independently of one another and to move independently along the
axes A1, A2 enables the exerciser to select a wide variety of
positions for exercise, some of which are illustrated in FIGS. 4-8.
In FIG. 4, both of the arms 90 have been pivoted along the axis A2
so that their distal ends 93 are relatively near the underlying
surface. This configuration can be used by the exerciser for a
variety of exercises, including bicep curls, seated rowing
movements, seated chest press movements, squats, shoulder raises,
and the like. In FIG. 5, both of the arms 90 have been moved so
that their distal ends 93 are raised to an elevation near the top
of the frame 22. In this configuration, the exerciser can perform
exercises such as lat pulldowns, triceps extensions, and the like.
In addition, the arms 90 may be moved to different heights (see
FIG. 6) for other exercises. Also, the exerciser may use one handle
110a while stabilizing himself with the arm 90 associated with the
other handle 110b, particularly when standing on one foot as he
engages the handle 110a with the other foot. Preferably, this is
done when the supporting arm 90 is in a generally horizontal and
inward position.
[0043] In either of these configurations, or at any position in
between (the configuration illustrated in FIG. 1 is an example),
the exerciser may choose to position the arms 90 close together
(see FIG. 7) or much wider apart (see FIG. 8). Widening the arm
positions may be desirable for exercises such as pectoral fly
movements, reverse fly movements, certain rowing movements, and the
like. Narrowing the arm positions may be desirable for different
rowing movements, the bicep curl and tricep extension movements
discussed above, and the like. Other exercises and positions
desirable therefore will be apparent to those skilled in this
art.
[0044] To exercise with the exercise machine 20, the exerciser
selects a desired amount of resistance and inserts the pin 46 into
the lifting member 48 between two weights 44 that correspond to
that resistance. The exerciser then grasps one or both of the
handles 112 and pulls them away from the distal ends 93 of the arms
90. The grasping can be accomplished with one or both of the
exerciser's hands or feet as desired for the given exercise.
[0045] In the event that only one hand or foot is used for
exercise, the handle unit 110a, 110b that is not grasped or engaged
by the exerciser abuts its adjacent handle pulley assembly 100. The
handle unit 110a, 110b that is grasped by the exerciser is pulled
away from the handle pulley assembly 100. As the handle unit 110
moves, it is resisted by the cable 118 which, because of its
engagement with the pulleys of the pulley train 120 and the
anchoring provided by non-moving handle pulley unit 100, causes the
selected weights 44 in the weight stack 40 to rise. The illustrated
arrangement of the pulley train 121 reduces the selected resistance
by 75 percent; e.g., for each 10 pounds of weights selected, the
exerciser experiences 2.5 pounds of resistance.
[0046] In the event that the exerciser uses two hands or feet
simultaneously during exercise, the handle units 110a, 110b are
engaged and pulled away from their respective arms 90. This
movement is resisted by the cable 118 at each end. For exercises in
which the exerciser uses both hands or feet, the arrangement of the
pulleys in the pulley train 121 reduces the selected resistance by
50 percent; e.g., for each 10 pounds of weights selected, the
exerciser experiences 5 pounds of total resistance (typically 2.5
pounds in each handle unit 110a, 110b).
[0047] It should also be noted that, as the exerciser performs the
exercise, it may be preferred to grasp the handle 112 horizontally,
vertically, or at an oblique angle. The ability of the handle
pulley units 100 to rotate freely about the axis A3 defined between
the proximal and distal ends 91, 93 of the arm 90 and to engage one
of the pulleys 106, 108 irrespective of the orientation of the
handle pulley unit 100 to the arm 90 can facilitate the
exercise.
[0048] The foregoing is illustrative of the present invention and
is not to be construed as limiting thereof. Although exemplary
embodiments of this invention have been described, those skilled in
the art will readily appreciate that many modifications are
possible in the exemplary embodiments without materially departing
from the novel teachings and advantages of this invention.
Accordingly, all such modifications are intended to be included
within the scope of this invention as defined in the claims. The
invention is defined by the following claims, with equivalents of
the claims to be included therein.
