DETAILED DESCRIPTION OF THE INVENTION
[0038] A mobile fitness system may comprise one or more modules
capable of mounting on a vehicle rack. The vehicle may comprise,
for example, a contractor's work truck, or other vehicle. In one
embodiment, the vehicle rack may be incorporated into the vehicle
or part of the vehicle, while in other embodiments, the vehicle
rack may comprise an add-on rack. For example, in one such
embodiment, a vehicle rack may comprise any of the models of
TracRac vehicle racks manufactured by TracRac, Inc. of Fall River,
Mass.; any of the models of vehicle racks manufactured by DeWALT
Industrial Tool Co. of Baltimore, Md. such as the SteelTruss line
of racks; any of the models of Xsportster truck racks by Thule AB
of Sweden; or any other type and form of vehicle rack.
[0039] For example, referring to FIG. 1, illustrated is a
perspective view of an embodiment of a vehicle rack 100, mounted on
a pickup truck 112. In some embodiments, a vehicle rack 100 may be
mounted on other vehicles, including cars, flatbed trucks, vans, or
other vehicles. In one embodiment, a vehicle rack 100 may comprise
horizontal sliding rails 102a-102b (referred to generally as rails
102 or bed rails 102). One or more rack bars 104a-104b (referred to
generally as racks 104, rack bars 104, or load bars 104), may be
mounted to rails 102. In many embodiments, rack bars 104 may be
slidingly positioned on rails 102 and locked or clamped into place
via locking mechanisms 110.
[0040] A rack bar 104 may comprise a pair of uprights 108 and a
cross bar 106a-106b (sometimes referred to as a cross bar 106, load
bar 106, and sometimes referred to as rack bars).
[0041] In some embodiments, a rack bar 104 may comprise one or more
additional supports, such as diagonal supports, to prevent torsion
or otherwise support heavier loads. In some embodiments, a rack bar
104 may include cleats or other mounting hardware. In many
embodiments, rack bars 104 may have user-adjustable heights, such
that cross bars 106 may be positioned at variable distances from
the ground. In some embodiments, the height may be continuously
variable, while in other embodiments, the user may select from a
plurality of predetermined heights. For example, uprights 108 may
include one or more pre-drilled holes, a sliding upper portion, and
a locking pin for locking the sliding upper portion into place via
one of the pre-drilled holes.
[0042] As shown in FIG. 1, in many embodiments, horizontal cross
bars 106 are at a substantial height from the ground, frequently
above head level, but typically within arm's reach from the ground.
Accordingly, a lateral extension at or above the level of cross
bars 106 may enable a user to hang from the bars and perform
various free-hanging exercises, such as pull-ups. Furthermore,
other exercise equipment may be hung from such lateral extensions,
providing a variety of exercises. Referring now to FIGS. 2A-2D,
illustrated are front, side, top, and isometric views of an
embodiment of an extension bar or extension rail 200 for supporting
fitness equipment or for performing free-hanging exercises. In
brief overview, extension rail 200 may comprise an extended rail
202, connected to one or more risers 204a-204b, each fast to a foot
208a-208b. Feet 208a-208b may include a hole 206a-206b for
fastening the extension rail 200 to a cross bar 106. In use,
extension rail 200 may attach to cross bar 106 or similar elements
of a vehicle rack with tie-down screws or clamps, and may extend
laterally outward and away from the side of the bed of the truck,
parallel with cross bar 106. When in position for use, extension
rail 200 may allow for various free-hanging exercises, as well as,
in some embodiments, the attachment of still rings, ropes, and
other suspension devices, such as the TRX Suspension trainer by
Fitness Anywhere, LLC of San Francisco, Calif. In other
embodiments, extension rail 200 may be configured for attachment of
punching bags, heavy bags, pulleys and weights, or other devices,
such as the Jungle Gym XT by LifelineUSA of Madison, Wis. When not
in use, extension rail 200 may be tied down to the rack
longitudinally parallel with the length of the truck bed.
[0043] Referring first to FIG. 2A and in more detail, an extension
rail 200 may comprise a horizontal beam or rail 202. Extension rail
200 may be constructed of steel, iron, aluminum, or any other stiff
and strong material capable of supporting the weight of a user. In
some embodiments, extension rail 200 may be constructed from wood
or a hard plastic, such as ABS plastic. In some embodiments,
extension rail 200 or a portion of extension rail 200, such as beam
202, may be solid, while in other embodiments, the rail or beam may
be hollow. For example, in one embodiment, beam 202 may comprise a
tubular length of steel. Beam 202 may be of any length sufficient
to allow a user to hang freely when extended past the side of a
vehicle, such as one foot, two feet, four feet, six feet, or any
other length. Beam 202 may have any diameter or width, such as one
inch, one and a half inches, two inches, four inches, six inches,
etc. In one embodiment, beam 202 may have a diameter sized to be
grasped by a human hand.
[0044] In some embodiments, beam 202 may have a round
cross-section, while in other embodiments, beam 202 may be square,
hexagonal, octagonal, or any other cross-section. In one
embodiment, a first portion of beam 202, such as the portion
attached to and between risers 204a-204b may have a first
cross-section, such as square, while a second portion of beam 202,
such as the portion extending longitudinally from riser 204b away
from riser 204a, may have a second cross-section, such as
octagonal. This may be done for ease of manufacture or welding to
risers, while simultaneously providing a comfortable grip for a
user's hand. In some embodiments, beam 202 may have an end cap,
preventing a user's hand from sliding off the end of the beam while
in use, as well as preventing injury. In some embodiments, an end
cap may be of a similar material to beam 202 or may be incorporated
into beam 202, such as a broadened or enlarged terminal portion of
a few inches or less. In other embodiments, an end cap may be of a
different material and may be placed over the end of the beam 202,
such as a rubber cap.
[0045] In many embodiments, one or more holes may pass through beam
202 in one or more predetermined positions for attachment of
additional equipment. For example, beam 202 may include a lateral
hole six inches from the end of beam 202 for accepting a hook
attached to a chain of a heavy bag, such that beam 202 may support
the bag in position for use. Holes may be vertical, horizontal, or
in any other orientation. In other embodiments, additional
equipment may be simply hung over beam 202, without requiring to be
secured via a hole. In a further embodiment, said equipment may
include a clamp or other feature to secure the equipment to beam
202. In another further embodiment, beam 202 may have one or more
projections or protruding pins or similar features, preventing an
item of equipment hanging over the beam from sliding past the
projection.
[0046] Extension rail 200 may comprise one or more risers
204a-204b, referred to generally as risers 204, attached to and
extending ventrally from beam 202. In one embodiment, extension
rail 200 may have a single riser of sufficient length and strength
to prevent rotation of beam 202 due to torque when in use. For
example, the riser may be one foot long, two feet long, or any
other length. In other embodiments, as shown, extension rail 200
may comprise two or more risers 204. In such embodiments, risers
204 may be of substantially shorter length while still preventing
rotation when secured to a vehicle rack. Where multiple risers are
employed, risers may be of any spacing, such as six inches apart,
one foot apart, two feet apart, two and a half feet apart, three
feet apart, or any other distance.
[0047] As shown in FIG. 2B, risers 204 may, in some embodiments, be
narrower than beam 202. In other embodiments, risers 204 may be of
the same width as beam 202 or wider. Risers 204 may be of any
material, the same or different from the material of beam 202.
Risers 204 may be of any height, such as six inches, three inches,
one foot, or any other height. In one embodiment, risers 204 may be
of sufficient height to position beam 202 at a predetermined
distance from the ground when positioned for use on a vehicle
rack.
[0048] In some embodiments, a riser 204 may be attached or fast to
a foot 208a-208b, referred to generally as a foot 208, which may
extend laterally from a terminal end of a riser 204. Foot 208 may
further comprise one or more holes 206a-206b, referred to generally
as holes 206, for attachment via tie-downs or clamps to a vehicle
rack. Holes 206 may be threaded or unthreaded.
[0049] The diameter of holes 206 may be sized responsive to
tie-down or clamp features of a vehicle rack. For example, in some
embodiments, a vehicle rack cross bar may include threaded holes,
and holes 206 may be of similar diameter, allowing a bolt to be
threaded through a hole 206 of a foot 208 and through a hole of the
cross bar. In other embodiments, a vehicle rack may utilize
expandable clamps that may be positioned at any point along a cross
bar, and hole 206 may be sized to allow use of said expandable
clamps. In some embodiments, clamps may be provided with extension
rail 200.
[0050] As shown in FIGS. 2B-2D, in some embodiments, feet 208 may
extend laterally past beam 202. In other embodiments, feet 208 may
not extend beyond beam 202. In still other embodiments, feet 208
may extend beyond beam 202, but holes 208 may be placed in line
with an axis of beam 202. Although both shown extending to a right
side of beam 202, in some embodiments, feet 208 may extend
laterally to a left side of beam 202, both sides of beam 202, or
one foot 208 may extend laterally to a left side while a second
foot 208 extends laterally to a right side of beam 202.
[0051] Referring now to FIG. 2E, illustrated is a top view of an
embodiment of the extension rail of FIGS. 2A-2D installed on a
vehicle rack and positioned for use. As shown, in some embodiments,
multiple extension rails 200a-200d may be employed simultaneously.
Although shown extending to a right side of vehicle 112, in some
embodiments, extension rails 200 may be extended to a left side of
vehicle 112. In another embodiment, extension rails 200 may
extended on both sides of vehicle 112, allowing multiple
simultaneous users. As shown, additional vehicle racks 104a-104d
may be employed to provide support for corresponding rails
200a-200d. Two rails 200 may be employed simultaneously on any one
vehicle rack 104, with each extending laterally from a side of
vehicle 112. In some embodiments, pairs of extension rails 200 may
be placed approximately shoulder-width apart, allowing for pull-ups
in a neutral grip, tricep dips, or similar exercises, or attachment
of paired equipment such as gymnastic rings.
[0052] Referring now to FIG. 2F, illustrated is a top view of an
embodiment of the extension rail of FIGS. 2A-2E positioned for
transportation on a vehicle rack. As shown, when not in use, rails
200a-200d may be tied down longitudinally parallel to the length of
the vehicle. In some embodiments, as shown, a vehicle rack 106,
such as rack 104c may be moved to allow feet 208 to be secured to
the rack in position for travel. In other embodiments, extension
rails may include additional tie down holes, such as holes through
bar 202 between one or more risers 204, such that the rail may be
tied down via said hole when not in use.
[0053] Through the use of multiple extension rails 200, a large
number of users may train simultaneously, either via single or
paired extension rails, or equipment attached to said extension
rails. To accommodate even more users, an A-frame extension may be
employed. FIGS. 3A-3D are front, side, top, and isometric views of
embodiment of an A-frame extension 300 for supporting fitness
equipment or for performing free-hanging exercises. Although
discussed as an A-frame, in some embodiments, the frame may
comprise an extension rail and single leg, or a plurality of legs
joined by a crossbar. Accordingly, rather than an A-frame,
extension 300 may be an L shape, a D shape, an inverted-U shape, or
any other shape. In brief overview, an extension 300 may comprise a
beam 302 attached to one or more legs 304a-304b at a terminal end.
Extension 300 may be attached to a vehicle rack and extended
longitudinally from the vehicle, allowing user by users at the rear
of the vehicle, in addition to the sides of the vehicle through use
of extension rails 200. Additionally, while a significant portion
of extension rails 200 may be involved in securing the extension
rail to the vehicle rack, such as the length of extension rail
between risers 204a-204b, and may thus be unusable for fitness
training, an extension 300 may have nearly all of its length
usable, allowing large groups of simultaneous users.
[0054] Still referring to FIGS. 3A-3D, and in more detail, an
extension 300 may comprise a beam 302. Similar to an extension beam
202, beam 302 may be of metal, wood, hard plastic, or any similar
material. Beam 302 may have any cross section, such as circular,
square, octagonal, or any other shape. In some embodiments, a first
portion of beam 302 may have a first cross section, and a second
portion of beam 302 may have a second cross section. For example, a
first portion for attachment to a vehicle rack may be square,
rectangular or flat, while a second portion for grasping by a user
may be round. Beam 302 may be hollow, solid, or partially solid and
partially hollow. For example, in some embodiments, beam 302 may
comprise a tubular steel beam. Beam 302 may be of any length, such
as five feet, six feet, seven feet, ten feet, or any other length.
In some embodiments, beam 302 may have a diameter capable of being
grasped by a hand, such as two inches, three inches, or any similar
size. Accordingly, in such embodiments, a user may utilize beam 302
for free-hanging exercises. In other embodiments, beam 302 may have
a larger diameter for additional strength, and a user may attach
additional fitness equipment to beam 302 such as gymnastics rings.
In some embodiments, similar to those discussed above in connection
with extension rail 200, beam 302 may include one or more vertical
or horizontal holes for attaching fitness equipment, or one or more
protrusions to prevent fitness equipment from sliding freely along
the length of beam 302.
[0055] Beam 302 may be fixed to one or more legs 304a-304b,
referred to generally as legs 304. In one embodiment, as shown in
FIGS. 3C-3D, legs 304 may extend at symmetrical angles from beam
302, forming an A frame for supporting beam 302 while preventing
lateral movement of the beam. In some embodiments, legs 304 may be
of any length. For example, in one embodiment, legs 304 may be of
very long length, such as seven, eight, or nine feet in length,
supporting the beam 302 at or above head height from the ground
when in use. In other embodiments, legs 304 may be substantially
shorter, and may be joined in use to extension legs 306, discussed
in more detail below, allowing for portability and storage. For
example, legs 304 may be only one, two, or three feet in length, or
any other length. In some embodiments, legs 304 may be hollow or
partially hollow for holding extension legs 306, discussed in more
detail below. Although illustrated in an A-configuration, in some
embodiments, legs 304 may be attached to a crossbar (not
illustrated) that may be attached to the terminal end of beam 302,
forming an inverted-U or pi-shape. In other embodiments, a single
leg 304 may be used to support beam 302. In a further embodiment,
one or more ropes, straps, or cables may be attached to beam 302
and connected to stakes, weights, or other securing means to
provide lateral tension to prevent beam 302 from moving, similar to
tension methods used in securing tents.
[0056] Referring now to FIGS. 3E and 3F, illustrated are side and
end views, respectively, of an embodiment of extension legs
306a-306b, referred to generally as extension legs 306) for an
embodiment of the A-frame extension of FIGS. 3A-3D. FIG. 3G is a
perspective view of an embodiment of the A-frame extension of FIGS.
3A-3D and extension legs of FIGS. 3E-3F. Extension legs 306 may
comprise a leg 308a-308b attached to a foot 310-310b. Leg 308a-308b
may be of similar material and construction as legs 304 of A-frame
extension 300, but in many embodiments, may be narrower in
diameter. As shown in FIGS. 3F and 3G, extension legs 306 may be
inserted into hollow ends of leg 304 for use in supporting beam 302
at an appropriate height from the ground, and may be removed for
portability and storage. In some embodiments, legs 304 may be
partially hollow or have a stop at a predetermined position within
the leg, such that an extension leg 306 may be inserted to a
specified distance. In another embodiment, legs 304 may have a
partial crimp at a predetermined position, preventing extension
legs 306 from sliding further into leg 304. In other embodiments,
extension legs 306 may be fully inserted in legs 304, such that
extension legs are prevented from further travel by beam 302. In
still other embodiments, a leg 308 may include a hole at or near a
terminal end of the leg to be secured in place via a pin through a
corresponding hole in leg 304. In still other embodiments, leg 308
may include a threaded portion corresponding to a threaded portion
on the inside of leg 304, such that the extension leg may be
screwed securely into position for use.
[0057] A foot 310 may be attached to a terminal end of a leg 308.
In some embodiments, a foot 310 may be a flat plate angled to lie
flat against a surface when A-frame extension is in use. In other
embodiments, a foot 310 may include a spike to be driven into soft
ground. In still other embodiments, a foot 310 may include a
threaded portion or non-threaded portion sized to meet with a plate
312a-312b, referred to generally as plates 312. Plate 312 may
comprise a plate for spreading force from an extension leg 306 over
a larger area of ground. In some embodiments, plate 312 may be
weighted, to prevent accidental movement of extension legs during
use of the A-frame extension. In one embodiment, plate 312 may
include a textured or spiked portion, for increasing friction with
the ground while in use. In other embodiments, foot 310 may be
sized to fit within a center hole of a disc weight or barbell
plate. Barbell plates, which may be readily available, may then be
used to secure the A-frame extension for use.
[0058] Beam 302 of an A-frame extension 300 may be secured to a
cross bar of a vehicle rack for use. Different mounts 314 may be
used, example embodiments of which are illustrated in FIGS. 3H and
3I. Referring first to FIG. 3H, illustrated is an isometric view of
an embodiment of a mount 314a for an A-frame extension. In brief
overview, in some embodiments, a mount for an A-frame extension may
comprise an upright 320 attached to a mounting plate 316. Mounting
plate 316 may have one or more holes 318a-318b for clamps or
threaded bolts for attachment to a vehicle rack cross bar. Upright
320 may, in some embodiments, include a hole 322 with an inner
diameter sized to accommodate beam 302, supporting an end of the
beam and preventing lateral motion. In other embodiments, as shown
in FIG. 3I, upright 320 may include two arms 324, with each
including a hole 326 for a pin. In such embodiments, beam 302 may
have a corresponding hole, such that a pin may be slid through
holes 236 and the corresponding hole in beam 302, preventing any
lateral or longitudinal motion of beam 302.
[0059] Still referring to FIG. 3H, and in more detail, in some
embodiments, a mount for an A-frame extension may comprise an
upright 320 attached to a plate 316. In some embodiments, upright
320 and plate 316 may form an L-shape or be attached at a 90 degree
angle, while in other embodiments, upright 320 and plate 316 may be
attached at any other angle. In many embodiments, upright 320 and
plate 316 may be formed from a single piece of material, such as
steel or iron, bent or cast in a bent shape.
[0060] In some embodiments, plate 316 may comprise one or more
mounting holes 318a-318b, referred to generally as mounting holes
318 or tie down holes 318. In some embodiments, tie down holes 318
may be threaded, while in other embodiments, tie down holes 318 may
be unthreaded. In some embodiments, and as discussed above in
connection with mounting holes of extension rails, tie down holes
318 may be sized to accommodate bolts, knobs, clamps, or other tie
down hardware for securing the mount 314 to a crossbar of a vehicle
rack.
[0061] In some embodiments, as shown in FIG. 3H, upright 322 may
comprise a hole 322. In many embodiments, hole 322 may have an
inner diameter of slightly larger than an outer diameter of beam
302, allowing beam 302 to be inserted into hole 322 to form a
prismatic joint. Mount 314 may then provide vertical support for
beam 302, as well as preventing lateral translation of the
beam.
[0062] In other embodiments, as shown in FIG. 3I, upright 322 may
include a notch or have two upper plates 324 spaced apart by at
least a diameter of beam 302. Each plate 324 may include a hole 326
to allow a pin (not illustrated) to be slid through holes 326 and a
corresponding hole through beam 302 to form a hinged joint. Mount
314 may then provide vertical support for beam 302, as well as
preventing both lateral and longitudinal translation of the beam.
In some embodiments, as shown, each plate 324 may be of greater
width than upright 322. In other embodiments, upright 322 may be
thicker, with the same thickness as each plate 324. The latter
embodiments may be heavier, but may also be stronger as well as
cheaper to manufacture.
[0063] Referring now to FIG. 3J, illustrated is a perspective view
of an embodiment of an A-frame extension 300 and extension legs
306a-306b mounted to a vehicle rack 104b. As shown, extension legs
306a-306b may be of sufficient length to support beam 302 parallel
to the ground. Beam 302 may then be used for free-hanging exercises
by multiple users simultaneously, and/or may support one or more
items of fitness equipment including ropes, chains, rings, pulleys
and weights, punching bags or heavy bags, elastic bands, or any
other type and form of fitness equipment.
[0064] Other types of fitness equipment may also be supported by
the mobile fitness system discussed herein. For example, referring
briefly to FIG. 4A, illustrated is a front view of an embodiment of
a fitness apparatus 400 utilizing a door 404 for structural
support, such as the Weider X-Factor Door Gym manufactured by ICON
Health & Fitness of Logan, Utah; the Altus Home Gym
manufactured by Altus Athletic Manufacturing Co. of Altus, Okla.;
the Home Gym System by American Fitness of Beaverton, Oreg.; or any
other type and form of door-mounted fitness apparatus. In brief
overview, a fitness apparatus 400 may comprise a plurality of door
frame supports 402a-402d, which may be connected by elastic cables
406 through pulleys 408. A user may grasp handles 410a-410b to
perform a variety of dynamic strength exercises. As shown in the
isometric view of FIG. 4B, each door frame support 402a-402d may
comprise a U-shaped portion to be placed over or under the door 404
with the door providing support and tension to elastic cables 406.
Fitness equipment of this sort may be used with the mobile fitness
system via a simulated door frame, fabricated to the same
dimensions of an ordinary household door, but with an upper portion
designed to attach to a vehicle rack, and a lower portion designed
with a receiving channel for the vehicle tire to be driven over,
anchoring the lower portion to the ground. Simulated door frames
may be utilized on both sides of the vehicle simultaneously,
providing capability for multiple users. When not in use, the upper
and lower portion of the simulated door frame may be removed and
easily stored and transported.
[0065] Referring now to FIGS. 5A-5D, illustrated are front, top,
bottom, and side views, respectively, of an embodiment of a
simulated upper portion 500 of a door for supporting a fitness
apparatus 400. In brief overview, the upper portion or top frame
500 may comprise a horizontal bar or beam 502, attached to one or
more vertical risers 506a-506b. Each riser 506a-506b may be
attached to a horizontal mounting plate 508a-508b with a channel to
slide over a cross bar of a vehicle rack. Each mounting plate
508a-508b may include one or more tie down or mounting holes
510a-510b for securing the top frame 500 to a vehicle rack. Beam
502 may be fixed to a plurality of equipment attachment points
504a-504d.
[0066] Still referring to FIGS. 5A-5D and in more detail, a top
frame 500 may comprise a horizontal beam 502. Beam 502 may be wood,
metal, plastic, or any other stiff material or combination of
materials. In some embodiments, beam 502 may have a length
equivalent to a standard household doorframe, such as two and a
half or three feet, while in other embodiments, beam 502 may be any
other size, including larger or smaller. In some embodiments, beam
502 may be the same thickness as a standard door, such as two
inches, or may be thinner. In embodiments in which beam 502 is
thinner than a standard door, top frame 500 may include a plurality
of attachment points 504a-504d or plates fixed to beam 502 to add
thickness and support door frame supports 402 of fitness equipment
400. In other embodiments, beam 502 may be thicker than a standard
door, and attachment points 504a-504d may comprise notches or
indentations in beam 502, allowing attachment of equipment while
preventing the equipment from sliding laterally across beam 502. In
some embodiments, as shown, attachment points 504a-504d may extend
lower than beam 502, providing a greater surface area for contact
with door frame supports 402 of fitness equipment, while reducing
the weight of top frame 500. Attachment points 504a-504d may
comprise pairs for a "narrow" setting and "wide" setting for use of
a door frame attached fitness apparatus. For example, outer
attachment points may be used for a wide setting, while inner
attachment points may be used for a narrow setting.
[0067] Top frame 500 may comprise one or more risers 506a-506b,
referred to generally as risers 506. Risers 506 may be attached to
beam 502, and may be of any height, width, or thickness. Risers 506
may be of wood, metal, plastic, or any combination of one or more
stiff materials. In some embodiments, beam 502 and risers 506 may
be cast or forged together, while in other embodiments, beam 502
and risers 506 may be welded, bolted, or otherwise fastened
together. Risers 506 may provide a vertical displacement from a
vehicle rack cross bar, both to allow attachment of door frame
supports 402 of fitness equipment at proper height and to prevent
supports 402 from being obstructed by the rack cross bar.
[0068] Risers 506 may attach to one or more mounting plates
508a-508b, referred to generally as mounting plates 508. Mounting
plates 508 may be wood, metal, plastic, or any combination of one
or more stiff materials for attachment to a vehicle rack. In some
embodiments, mounting plates 508 may be flat, while in other
embodiments, mounting plates 508 may be notched or have an inverted

Mounting plates 508 may include one or more mounting or tie down
holes 510a-510b for use of bolts, clamps, or other hardware to
attach top frame 500 to a vehicle rack cross bar. Mounting holes
510 may be threaded or unthreaded. As shown, in many embodiments, a
top frame 500 may comprise two risers 506 and mounting plates 508
to attach to two vehicle rack cross bars, preventing the apparatus
from rotating in use. Mounting plates 508 may of any length, width,
or thickness sufficient to support top frame 500 in use.
[0069] Referring now to FIGS. 6A-6C, illustrated are front, top,
and end views of an embodiment of a simulated lower portion or
bottom frame 600 of a door for supporting a fitness apparatus 400.
In brief overview, a bottom frame 600 may comprise a horizontal
beam 602. Beam 602 may be attached to or comprise one or more
attachment points 604a-604d. Beam 602 may also comprise or be
attached to a vehicle tire receiving channel 606 for anchoring
bottom plate 600 to the ground by positioning a vehicle tire on top
of receiving channel 606. In some embodiments, receiving channel
606 may comprise a stop 608 to prevent the vehicle from driving
beyond a predetermined position over the channel 606, and may
comprise a backstop 610 to prevent the channel from sliding out
from under the vehicle tire.
[0070] Still referring to FIGS. 6A-6C and in more detail, a bottom
frame 600 may comprise a horizontal beam 602. Beam 602 may be wood,
metal, plastic, or any other stiff material or combination of
materials. In some embodiments, beam 602 may have a length
equivalent to a standard household doorframe, such as two and a
half or three feet, while in other embodiments, beam 602 may be any
other size, including larger or smaller. In some embodiments, beam
602 may be the same thickness as a standard door, such as two
inches, or may be thinner. In embodiments in which beam 602 is
thinner than a standard door, bottom frame 600 may include a
plurality of attachment points 604a-604d or plates fixed to beam
602 to add thickness and support door frame supports 402 of fitness
equipment 400. In other embodiments, beam 602 may be thicker than a
standard door, and attachment points 604a-604d may comprise notches
or indentations in beam 602, allowing attachment of equipment while
preventing the equipment from sliding laterally across beam 602. In
some embodiments, as shown, attachment points 604a-604d may extend
above beam 602, providing a greater surface area for contact with
door frame supports 402 of fitness equipment, while reducing the
weight of bottom frame 600. Attachment points 604a-604d may
comprise pairs for a "narrow" setting and "wide" setting for use of
a door frame attached fitness apparatus. For example, outer
attachment points may be used for a wide setting, while inner
attachment points may be used for a narrow setting.
[0071] Beam 602 may be attached to a receiving channel 606, which
may comprise a flat plate for a vehicle tire to be driven onto to
anchor the bottom frame 600 to the ground. In some embodiments,
channel 606 may be wider than the width of a vehicle tire to allow
a user to drive the vehicle onto the plate easily. In some
embodiments, channel 606 may be bounded on one or more sides by a
vehicle stop 608 and/or backstop 610. Vehicle stop 608 may comprise
a wall, plate, or beam positioned at one end of receiving channel
606 to stop a vehicle tire from rolling off of channel 606. In some
embodiments, vehicle stop 608 may be metal, wood, plastic, or any
combination of materials, and may comprise an upwardly-bent portion
of a plate of receiving channel 606. In many embodiments, vehicle
stop 608 may not be required to provide structural support to any
other component, and so may be relatively thin. In other
embodiments, vehicle stop 608 may act as a brace for a backstop
610, and may be thicker.
[0072] Backstop 610 may comprise a beam, plate, or wall to prevent
receiving channel 606 from sliding laterally from under a vehicle
tire. In use, bottom frame 600 may be pulled outward by a user as
various exercises are performed. On some surfaces, such as grass,
gravel, sand, or dirt, there is a possibility that channel 606
could be pulled from under the vehicle, releasing suddenly and
causing injury. Backstop 610 prevents this motion by acting as a
stop against the vehicle tire.
[0073] Referring now to FIG. 7, illustrated is a front view of an
embodiment of the top frame 500 of FIGS. 5A-5D and bottom frame 600
of FIGS. 6A-6C installed on an embodiment of a vehicle rack,
supporting an embodiment of a fitness apparatus 400. As shown, when
positioned on a vehicle rack and beneath a vehicle tire, beams 502
and 602 may be parallel and separated by the height of a door,
providing attachment points 504 and 604 at appropriate distances
for use of fitness apparatus 400.
[0074] Referring briefly to FIG. 8, illustrated is a perspective
view of an embodiment of a mobile fitness system employing multiple
equipment stations. As shown, extension bars and frames may be
attached to the vehicle rack at multiple places, allowing for
groups of as many as fifteen, twenty, or more users to
simultaneously train in circuit fashion, rotating from one station
to the next around the vehicle. The equipment may be quickly broken
down for travel and storage, allowing for fitness training
anywhere.
[0075] In addition to free-hanging, cable systems, and other
exercise apparatuses, the mobile fitness system may further
comprise a Fibonacci Wheel, or semi-circular fitness apparatus to
allow users to perform push-ups, inverted pull-ups, or other
exercises at a variety of predetermined angles. Referring first to
FIG. 9A, illustrated is a side view of use of an embodiment of a
Fibonacci Wheel or semi-circular fitness apparatus 900. A Fibonacci
Wheel 900 may comprise a spiral cross-section along circular arcs
from opposite squares of a Fibonacci tiling. The wheel may comprise
multiple handholds or bars at predetermined positions. By grasping
these bars, a user 902 may perform exercises at a variety of
angles. For example, a user may perform a push-up on the ground
with his or her arms at an approximately 90 degree angle from his
or her body. By grasping a bar elevated off the ground, the user
may perform a push-up at a reduced angle of 60 degrees, 45 degrees,
or any other angle. This may be used to target different muscle
groups, as well as reducing the difficulty. Alternately, in some
embodiments, the user may place their ankles over a bar elevated
from the ground and perform push-ups with their hands on the
ground. Arm-body angles greater than 90 may be achieved in this
fashion, increasing the difficulty. Additionally, a user may
perform a climbing exercise, climbing up and down along the wheel
with alternating hands. Users may also perform pull-ups and tricep
dips or other exercises.
[0076] Referring now to FIG. 9B, illustrated is a perspective view
of an embodiment of a Fibonacci Wheel or semi-circular fitness
apparatus 900. Although shown in a spiral, in many embodiments, the
fitness apparatus may have a circular or semi-circular cross
section or profile. Wheel 900 may have a large radius in many
embodiments, such that a user hanging from the top of the wheel
with arms outstretched may have their feet off the ground.
[0077] Wheel 900 may comprise two or more rims 902a-902b, referred
to generally as rims 902. In some embodiments, rims 902 may be
steel, iron, wood, plastic, or any other stiff material capable of
supporting the weight of one or more persons. Rims 902 may be
solid, hollow, or a combination of solid and hollow. In some
embodiments, rims 902 may comprise tubular steel elements, reducing
weight while maintaining strength. In many embodiments, rims 902
may be positioned wider than shoulder height apart. In some
embodiments, an upper terminal end of each rim 902 may include a
plate, c-shaped portion, u-shaped portion, or similar feature for
mounting to a horizontal bar such as an A-frame extension 300. In
some embodiments, the mount may include one or more mounting holes
to securely fasten rims 902 to the bar via bolts, pins, or
clamps.
[0078] In some embodiments, rims 902 may be joined by one or more
cross bars 904. Cross bars 904 may provide structural strength and
positioning to keep rims 902 parallel, as well as providing grips
for hands or bars for ankles during push-ups or other exercises.
Cross bars 904 may be wood, metal, plastic, or any other material,
and may be welded, bolted, or otherwise fastened to rims 902. In
some embodiments, cross bars 904 may also extend outward from rims
902 (not illustrated). In some embodiments, cross bars 904 may be
round in cross section, while in other embodiments, cross bars 904
may be square, octagonal, or any other shape. In many embodiments,
cross bars 904 may have a diameter sized for grip by a user's
hands. Although shown as straight bars, in many embodiments, a
cross bar 904 may have a bent profile or be fixed at a
non-perpendicular angle to rims 902, allowing for push-ups and
other exercises with a more neutral, less supinated position of the
user's wrists and forearms, reducing the risk of stress injury.
[0079] In some embodiments, rims 902 may also be attached to one or
more grips 906. In many embodiments, grips 906 may be similar in
material, cross section, and diameter to cross bars 904, but may
not extend fully between rims 902. In many embodiments, as shown,
grips 906 may also extend outward from rims 902, allowing for grips
wider than the distance between rims 902. Due to the open space
between each pair of grips 906 attached to rim 902a-902b, a user
may perform push-ups or other exercises at extreme extensions,
sometimes referred to as guillotine push-ups, in which the user
lowers his body past the plane between the hands. This may place
extra stress on the shoulder muscles, for example. As discussed
above in connection with cross bar 904, in various embodiments,
grips 906 may be straight, bent, perpendicular to rims 902, or
non-perpendicular to rims 902.
[0080] Referring briefly to FIG. 9C, illustrated is a perspective
view of an embodiment of a mobile fitness system comprising an
A-frame extension 300 and a Fibonacci Wheel 900. As shown, the
wheel 900 may be installed connected to a horizontal beam 302 of
extension 300, providing capability for users to perform a variety
of exercises at predetermined angles at any time, anywhere.
