Description
RELATED APPLICATION
[0001] This application is a divisional of U.S. patent application
Ser. No. 10/745,417, filed Dec. 22, 2003, which is a
Continuation-in-Part of U.S. patent application No. 09/715,242,
filed Nov. 17, 2000, now U.S. Pat. No. 6,685,601. The prior
applications are incorporated herein by reference.
BACKGROUND
[0002] This invention relates to weight lifting, and in particular,
to a weightlifting system with safety cage that can be configured
into a compact size when not in use, e.g., for storage.
[0003] Weight lifting continues to increase in popularity. Today,
weight lifting attracts participants having varying ages, abilities
and goals. Participants seek both the general health benefits and
the sports-specific performance gains that can be achieved through
a disciplined weight training program. Many participants belong to
health clubs that typically have a wide array of weight lifting
equipment. Others prefer to exercise in their homes, e.g., because
of convenience, cost or schedule.
[0004] Although high quality and effective weight lifting equipment
is available, such equipment is usually too large and too expensive
for most people to use in their home. A typical equipment line
usually includes at least several pieces, with each piece being
specifically designed for performing a single exercise. Thus,
outfitting a home with an adequate array of this equipment is
usually too expensive and requires too much space.
[0005] Some exercise systems have an integrated apparatus such that
a variety of different exercises can be performed, but the
apparatus takes up less space than individual pieces dedicated to a
single exercise. Some of these systems, including, e.g., Bowflex,
BodySmith, and Hoist are marketed for home users. In such systems,
the resistance used for exercises is usually provided by tension
elements or stacked weight plates. Some users, however, prefer the
additional benefits of exercising with free weights (i.e.,
traditional barbells and plates) because doing so improves
coordination and balance, as well as strength and endurance.
[0006] In a club environment, a participant performing a
potentially dangerous lift with free weights (such as, e.g., a
bench press or military press) can often locate someone to serve as
a spotter. Some clubs also have "safety cages" designed to prevent
a loaded barbell from crushing the user in the event of a failed
lift. These safety cages allow users to perform the exercises
safely without the assistance of a spotter. The safety cages found
in clubs, however, are rigid structures, and they cannot be adapted
for use in a full array of exercises nor conveniently reconfigured
in a compact position.
[0007] It would be advantageous to provide a full-featured weight
lifting system having an integrated safety cage suitable for using
free weights in a wide range of exercises, yet able to be
configured in a compact position, e.g., for storage in the
home.
SUMMARY
[0008] These and other advantages are provided by the compact
weight lifting system of the present invention, which is also
sometimes referred to as a frame system.
[0009] According to embodiments of the invention, the compact
weight lifting system has a safety cage that can be reconfigured
between at least compact (i.e., storage) and use positions. The
safety cage has sides that are movable relative to a back or rear
frame member of the safety cage, unlike conventional rigid safety
cages.
[0010] To make the system compact, the sides are positioned closer
to the rear frame member. To configure the safety cage for use, the
sides are positioned to extend outward from the rear frame member,
the sides and the rear frame member thereby defining an exercise
space. In some embodiments, the sides can be spread outward (i.e.,
at an angle of more than 90 degrees relative to the rear frame
member) or positioned at an angle of less than 90 degrees relative
to the rear frame member.
[0011] The safety cage has elements, referred to below as "safety
bars," that can be positioned to prevent a weight load from
crushing the user in the event that the user fails to complete a
planned lift. The safety cage also supports weighted barbells and
extra weight plates when not in use.
[0012] In some embodiments, the sides are pivotably attached to
opposite ends of the rear frame member such that they can be folded
against each other when the system is configured in a compact
position. In other embodiments, the sides telescope relative to the
rear frame member. In still other embodiments, the sides fold and
telescope.
[0013] Some embodiments of the system include integrated barbell
guiding elements (i.e., Smith machine functionality) to assist a
user in keeping a loaded barbell level.
[0014] The safety cage serves as an overall framework through which
cables for supporting weight are routed and to which various
accessories can be coupled. Such accessories include, but are not
limited to, a cable operated carriage coupled to the safety cage, a
weight lifting bench, a leg exercise attachment, barbell holders, a
chin-up/pull-up bar, dip handles, foot holders (for sit-up
exercises), etc.
[0015] In addition, the system can be fitted with various
peripheral equipment to enhance the user's exercise experience,
including, e.g., an audio system, an exercise computer and/or a
beverage holder.
[0016] The system can be configured to use constrained plate-type
weights instead of or in addition to free weights.

DETAILED DESCRIPTION
[0068] The invention is a compact modular weight lifting system
with which a user can safely perform a complete range of lifting
exercises to provide a total body workout. In embodiments described
below, the system includes a support structure or safety cage that
can be easily reconfigured between at least a compact position and
a use position.
[0069] The safety cage has elements, e.g., safety bars, that can be
positioned to prevent a weight load from crushing the user in the
event that the user tires during the exercise. The safety cage also
supports weighted barbells and extra weight plates when not in use.
The safety cage serves as an overall framework through which cables
for supporting weight are routed and to which various accessories
can be coupled.
[0070] The system can include a bench coupled to the safety cage or
a bench configurable for use independent of the safety cage (i.e.,
a free standing bench) or a bench that is both coupleable and
configurable for independent use. When not required, the bench can
be stored or moved out of the way. The bench is segmented such that
it can be configured in a range of positions, including a flat
position (e.g., for bench press exercises), inclined positions
(e.g., for inclined press exercises), and an erect position (i.e.,
like a chair back, for shoulder press or other upper body
exercises).
[0071] To permit the safety cage to be configured in a compact
position, the sides are (1) folding (i.e., pivotable coupled to the
back), (2) in telescoping relation to the back, (3) folding and
telescoping, or (4) readily removable (i.e., without the use of
tools) from the back. Safety cages with each of these types of
sides are described below.
[0072] According to one embodiment, the system has a folding safety
cage in which the sides of the cage fold flat against each other
for compact storage of the system.
[0073] According to another embodiment, the system has a safety
cage with barbell guiding elements (i.e., similar to a Smith
machine) for assisting the user in positioning and guiding a
barbell during an exercise (e.g., overhead press, squat or lunge
exercises), and supporting the barbell when the user tires or the
barbell is not in use. With a Smith machine arrangement, opposite
ends of a barbell are held by holders that are coupled together
such that they translate along a guiding member and can be locked
in place at desired positions. In the second embodiment, the
horizontal members of the safety cage telescope for compact storage
of the system. In this embodiment, the rear frame member can have a
single upright member.
[0074] According to yet another embodiment, the system has a safety
cage with a single rear upright member similar to the second
embodiment, but the sides of the safety cage fold flat against each
other for compact storage, similar to the first embodiment.
[0075] According to a further embodiment, the system has a safety
cage with sides that pivot and telescope relative to the rear frame
member.
[0076] According to a still further embodiment, the system has a
safety cage with side frame members that are readily removable from
the rear frame member, and the rear frame member has brackets for
holding and locking the side frame members, e.g., when the safety
cage is configured in a compact position for storage.
[0077] As illustrated, the various embodiments are shown with free
weights (i.e., combinations of individual plates of standard
weights), but constrained stacked-plate weights could be
substituted.
Folding Safety Cage
[0078] As shown in FIGS. 1-7D, a compact weight lifting system 10
has a folding safety cage 12 with a rear frame member 14 and left
and right side frame members 16a, 16b, respectively. The rear frame
member 14 has a pair of rear uprights 20a, 20b that are connected
to each other by upper, intermediate and lower lateral members 22,
24, 26, respectively. Each of the uprights 20a, 20b is supported by
a respective foot 28a, 28b.
Pivoting Safety Cage Side Frame Members
[0079] The left and right side frame members 16a, 16b each have an
upper lateral member 30a, 30b, a lower lateral member 32a, 32b, and
a front upright 34a, 34b extending therebetween. Each lower lateral
member 32a, 32b has an attached foot 35a, 35b, respectively, that
is sized approximately the same height as the feet 28a, 28b.
[0080] The left and right side frame members 16a, 16b are each
pivotably connected to the rear frame member 14. Specifically, the
left side frame member 16a is pivotably connected to the rear frame
member 14 at the upper lateral member 30a by an upper pivot 36a,
and at the lower lateral member 32a by a lower pivot 38a.
Similarly, the right side frame member 16b is pivotably connected
to the rear side 14 at the upper lateral member 30b by an upper
pivot 36b, and at the lower lateral member 32b by a lower pivot
38b.
[0081] As shown in FIG. 4, the pivots 36a, 36b and 38a, 38b allow
the right side frame member 16b to be pivoted into contact with
(i.e., "folded flat against") the rear frame member side 14, and
the left side frame member 16a to be folded flat against the right
side 16b. Thus, the left side pivots 36a and 38a are spaced farther
from the rear upright 20a than the right side pivots 36b and 38b
are spaced from the upright 20b. This is referred to below as the
"offset pivot arrangement."
[0082] The left and right side frame members 16a and 16b can be
pivoted through a range of positions with respect to the rear frame
member 14. As shown in FIGS. 1-3, the side frame members 16a and
16b can be pivoted to a normal position approximately perpendicular
to the rear frame member 14. As shown in FIGS. 5A and 5B, the side
frame members 16a and 16b can be pivoted to a "spread outward"
position, e.g., to provide more room within the safety cage 12. As
shown in FIGS. 6A and B, the side frame members 16a and 16b can be
pivoted inwardly to a "wedged" position, as may be desired for
certain exercises.
[0083] FIGS. 7A, 7B and 7C are respective rear side, plan and right
side views showing the system 10 in a compact position. In one
particular implementation, the footprint of the system in the
compact position is about 18 inches by about 45 inches (and about
18 inches by about 55 inches with the vertical slider of FIG. 1).
For safety and/or convenience, the side frame members can be pinned
or cabled to a fixed surface such as a wall or otherwise locked in
place when the system 10 is in a compact position (using, e.g., the
pivot pins, other pins or any other suitable device).
[0084] A specific implementation of the upper left side pivot 36a
with a locking feature is described with reference to FIG. 5B. The
upper left side pivot 36a includes a pivot plate 37a with a series
of pivot plate holes 47a, a pivot pin 41a and a locking pin 43a.
The pivot plate 37a is fixed to the rear frame member 14 at the
junction of the rear upright 20a and the upper lateral member 22.
The locking pin 43a is sized to extend through an anchor hole 45a
near the end of the upper lateral member 30a and an aligned one of
the pivot plate holes 47a in the pivot plate 37a that corresponds
to a desired angle (e.g., about 135 degrees as shown in FIG. 5A) of
the left side frame member 16a. A camming fastener 49a (see FIGS.
5C and 5D) is positioned over a lower end of the locking pin 43a
and urged to a closed position to secure the upper lateral member
30a and the pivot plate 37a together, thereby holding the left side
frame member 16a in the desired position.
[0085] The upper right side pivot 36b is similar to the upper left
side pivot 36a, except the pivot plate 37b is smaller because the
pivot pin 41b is spaced closer to the anchor hole 45b to produce
the offset pivot arrangement described above. It is also possible
to configure the safety cage system 10 to pivot freely, thus
avoiding the need to include the locking pivots 36a, 36b.
[0086] The lower pivots 38a, 38b each have a pivot pin that is
aligned in the vertical direction with the respective one of the
upper pivot pins 41a, 41b.
Pivoting Safety Bars
[0087] The left and right side frame members 16a, 16b of the safety
cage 12 also include respective safety bars 39a, 39b. The safety
bars 39a, 39b are removably connected to the front uprights 34a,
34b and the rear uprights 20a, 20b, respectively, such that they
are suspended horizontally at various positions, e.g., as shown in
FIGS. 2 and 3. The safety bars 39a, 39b prevent a loaded barbell 99
from crushing a user, e.g., during a squat exercise (FIG. 2) or a
bench press exercise (FIG. 3). Although not illustrated, it may be
desirable in some applications to arrange the safety bars such that
one or both of them are angled (either the same angle or different
angles).
[0088] The safety bars 39a, 39b can be pivoted from a horizontal
position and secured in an upright position, as shown in FIG. 1.
Referring to the left safety bar 39a according to the illustrated
implementation, a lateral member 51a is pivotably attached by pins
53a to first flanges 55a and second flanges 57a. The first flanges
55a are positioned to straddle opposite sides of the upright 34a,
and are pivotably secured by a pin 59a extending through holes in
the first flanges 55a and the upright 34a. The second flanges are
positioned to straddle the upright 34a at a higher position, and
such that the shaft of a pin 61a passes through holes in the second
flanges and contacts a side of the upright 43a as shown. The user
can remove the pins and adjust the positions of the safety bars
while he is within the safety cage 12.
[0089] One common type of conventional safety bars is rods that are
inserted through aligned holes in the front and rear upright for
each side. The position of such a rod cannot be changed from within
the safety cage, e.g., during an exercise. Rather, the user must
leave the safety cage and face the front upright to withdraw the
rod and reinsert it in a different set of holes.
[0090] As shown in FIGS. 5A, a safety bar 81a, 81b is particularly
suited for use in applications where the side frame members 16a,
16b are pivoted at angles of other than 90 degrees with respect to
the rear frame member 14. The end of the safety bar 81b that
connects with the front upright 34b is the same as described above
for the safety bar 39b. The other end of the safety bar 81b,
however, is pivotably connected to a safety bar receiver 83b.
Essentially, the safety bar 81b has a hole that can be positioned
over a post on the receiver 83b. The safety bar 81b can then pivot
with respect to the receiver 83b as the side 16b is pivoted
inwardly or outwardly from the perpendicular position. (By
comparison, the safety bar 39b can pivot with the side 16b through
only a limited angular range.) The receiver 83b can be positioned
at different vertical positions on the rear upright 20b.
Bench Pivotably Attached To Safety Cage
[0091] As indicated above, the safety cage 12 also serves as a
framework to which other components are coupled. For example, a
bench 40 can be pivotably connected to the intermediate lateral
member 24 of the rear side 14. The bench 40 is hinged such that the
rear back portion 42 can pivot upwardly relative to horizontal. A
front seat portion of the bench 40 is supported by a pivoting bench
foot 87. As shown in FIG. 1, a leg lift attachment 46 can be
connected to the bench, if desired.
[0092] As shown, e.g., in FIG. 2, the bench 40 can be pivoted
upward and secured within the space between the uprights 20a, 20b,
with the bench foot 87 pivoting flat against a rear surface of the
bench, for performing exercises within the safety cage 12 that do
not require a bench or for storage. Further details of the bench
construction are described below.
[0093] Specifically, with reference to FIG. 3, the bench 40
includes a main frame member 40a that supports the back portion 42
and the seat portion 44, as well as a support member 40b pivotably
coupled to the back portion 42 and to the main frame member 40a
(partially obscured by the safety bar 39a). As best shown in FIG.
3, the seat portion 44 is slidingly translatable relative to the
main frame member 40a to a desired position (note the series of
spaced apertures 40c shown along the length of the main frame
member 40a). As can be seen by comparison between, e.g., FIG. 1 and
FIG. 3, sliding the seat portion 44 relative to the main frame
member 40a changes an inclination of the back portion 42 relative
to the seat portion 42. In the illustrated implementation, the seat
portion 44 can also be inclined relative to the main frame member
40a, in this case by repositioning a seat support member 44a
relative to a support pin 44b.
Carriage Configured To Travel Along Safety Cage Upright
[0094] The system 10 also includes a cable supported rolling weight
arrangement. Referring to FIG. 1, a carriage 50 is mounted to
slidingly move in a vertical direction along the rear upright 20a.
Thus, the carriage 50 travels along one of the structural members
of the safety cage 12.
[0095] As shown in FIG. 7D, the carriage 50 has a frame 93a
defining an approximately square opening sized slightly larger than
the rear upright 20a. The frame 93a is fitted with wheels 93b on
each of its four sides that contact the upright 20a so that the
carriage rolls smoothly along the upright 20a as it translates.
[0096] The carriage 50 is attached to a first end 52b of a cable
52a, with the second end 52c being routed over a first pulley 55c,
through an opening 54 near the upper end of the upright 20a,
through the upper lateral member 22, over a second pulley 57, and
out through an opening in the lower surface of the lateral member
22 approximately midway between the uprights 20a, 20b. The second
end 52c can be connected to an accessory, e.g., a lat bar 58. The
pulley 57 may be mounted at least partially inside the upright
20a.
[0097] In operation, the user grasps each end of the lat bar 58 and
sits on the bench 40. The user then pulls the lat bar 58 toward
himself, thus moving the carriage 50 upward along the upright 20a
against the weight carried by the carriage 50 and any resistance
exerted by the cable and pulleys.
[0098] Another cable 60 extends from an opening 62 in the lower
lateral member approximately midway between the uprights 20a and
20b and around a pulley 60a. A portion of the cable 60 (concealed
in the drawing) extends from the pulley through the lower lateral
member 26, over one or more additional pulleys (including one near
the opening 54 that is partially visible in FIG. 1), and through
the upright 20a. The cable 60 is of sufficient length to allow its
end to be drawn out of the upright 20a and attached to the carriage
50. When the cable 60 is not in use, this first end is stored on a
projection (not shown) within the upper lateral member 22 near the
opening 54. In use, with the first end of the cable 60 attached to
the carriage 50, the other end is attached to an accessory, such as
the leg lift attachment 46 as shown in FIG. 1.
[0099] The carriage 50 has a plate receiving bar 66 on which one or
more weight plates can be added according to the particular
exercise being performed. When the carriage 50 is not in use, it
rests on a carriage rest 68.
[0100] In an alternative arrangement as shown in FIG. 30, the
carriage 50 travels along separate upright rods 97 that are secured
to the safety cage 12, rather than the upright 20a.
[0101] A multi-position carriage system 748 is described below in
connection with FIGS. 28A-30.
Alternative Smith Machine Safety Cage With Folding Sides
[0102] As shown in FIGS. 12A and 12B, a safety cage system 710 has
front uprights fitted with a Smith machine mechanism and folding
safety side frame members, similar to the system 210 of FIGS. 10,
11A, 11B and 13.
[0103] Because the barbell is releasably secured, it can be easily
removed to allow use of the system 710 for other exercises or to
pivot the side frame members for storage. Except for the added
Smith machine functionality, the system 710 is similar in
construction and operation to the system 10 having the offset pivot
arrangement described above.
[0104] The system 710 as shown in FIGS. 12A and 12B is also fitted
with a wishbone-shaped rear lateral member 725 that replaces the
intermediate and lower lateral members 24, 26. With the bench 740
rotated to an upright position as shown in FIG. 12B and the lateral
member 725 pivoted to an approximately horizontal position
(approximately parallel to the floor), more space is available
within the safety cage 712 than with the embodiments with the
lateral members 24, 26. Also, the attached bench can be set in
alternative positions by pivoting the lateral member 725 into a
horizontal position. The lateral member 725 can, of course, be used
with other embodiments.
Smith Machine Safety Cage With Telescoping Horizontal Members
[0105] A system 110 has a safety cage 112 that telescopes (as
opposed to folding) to provide a compact footprint for easy
storage, and the front uprights of the safety cage 112 are fitted
with a Smith machine mechanism.
[0106] As shown in FIGS. 8 and 9, the safety cage 112 has a single
rear upright 120 joined to a upper lateral member 121, which is
joined to a curved upper lateral member 122. The sides 116a and
116b are fixed to a rear portion of the safety cage 112 and thus do
not pivot in the horizontal plane. As in the case of the first
embodiment, the system 110 includes a carriage 150 slidingly
coupled to a frame member, i.e., the rear upright 120.
Horizontal Members of Safety Cage Telescope For Storage
[0107] The front uprights 134a and 134b join the ends of the curved
upper lateral member 122. At the bottom, the uprights 134a, 134b
are joined to telescoping lower lateral members 132a, 132b.
Uprights 123a, 123b extend from positions rearward of the front
uprights 134a, 134b, and are joined together by a rear lateral
member 124. The front uprights 134a, 134b are joined to the
uprights 123a, 123b by respective telescoping safety bars 139a,
139b. For storage, the safety cage 112 is slid horizontally by
pushing the front uprights 134a, 134b in the direction A from the
position shown in FIG. 8, with the members 139a, 139b, 132a, 132b
telescoping through respective joints 141a, 141b, 143a, and 143b.
In the same motion, the curved upper lateral member 122 also slides
over the upper lateral member 121. As a result, the safety cage
becomes configured for storage as shown in FIG. 9.
Barbell Is Releasably Held In Smith Machine-Type Barbell
Holders
[0108] According to the Smith machine functionality of the system
110, barbell holders 180a, 180b are slidably movable along
respective rods 182a, 182b attached to the uprights 116a, 116b,
respectively. The barbell holders 180a, 180b (1) support the weight
of the barbell 99, (2) keep the barbell 99 level during movement,
and (3) can be selectively locked in place at a desired height
along the rods 182a, 182b. In contrast to conventional Smith
machine arrangements, the barbell holders 180a, 182b releasably
hold the barbell 99, such that the barbell 99 can be removed and
used freely.
[0109] As another benefit, the releasable bar holders 180a, 180b
can be repositioned to travel along and selectively engage an inner
side of appropriately configured uprights 134a, 134b (i.e.,
directly opposite the side shown in FIG. 8), thus moving the
position of the supported barbell within the safety cage 112. To
provide this benefit, the uprights 134a, 134b can be provided with
two sets of openings (i.e., in the outer side as shown and in the
hidden inner side). FIGS. 31-33 show the holders 980a, 980b
configured for travel along an inner side of the uprights 934a,
934b.
[0110] A specific implementation of the barbell holders 180a, 180b
is described in connection with FIGS. 8 and 12C-12G. The left
barbell holder 180a is similar to the right barbell holder 180b,
which is described in detail.
[0111] The barbell holder 180b is an assembly of three main
components: (1) a bearing 802b mounted on the left end of a shaft
804 of the barbell 99; (2) a holding member 806b, which is shaped
to receive and secure the bearing 802b, that holds the loaded
barbell 99 and is constrained to move in the direction of the rod
182b; and (3) a hook 808b attached to an inboard end of the bearing
802b that rotates with the shaft 804 into engagement with a
selected one of the series of spaced holes 810b formed in the outer
surface of the upright 134b.
[0112] In use, from a position as shown in FIG. 8, the user grabs
the shaft 804 with both hands between the hooks 808a, 808b, lifts
the barbell slightly to disengage the hooks 808a, 808b from the
engaged holes 810a, 810b, and rotates the shaft 804 slightly, thus
keeping the hooks 808a, 808b disengaged. With the shaft 804 in this
position, the user performs repetitions of a lift by raising and
lowering the barbell 99 while it is constrained to travel in the
direction of the rods 182a, 182b.
[0113] When the user completes a desired number of repetitions or
tires, the user can re-engage the hooks 808a, 808b with appropriate
holes 810a, 810b, thereby transferring the weight of the loaded
barbell 99 from the user to the safety cage 112.
[0114] Referring to FIG. 12E, which shows that holder 180b with the
shaft 804 removed and a section of the bearing 802b, the bearing
802b has an inner race 812b that is sized to be fixed (e.g., by a
press-fit, friction fit or welding) to the shaft 804 such that the
inner race 812b does not rotate relative to the shaft 804. An
inboard end of the inner race 812b has a groove 814b with opposing
flat surfaces 816b (FIG. 12F) that receive the hook 808b.
[0115] An outer race 818b surrounds and is rotatable relative to
the inner race 812b. Needle bearings 819b are positioned between
the inner race 812b and the outer race 818b. At an outboard end
820b, the outer race has a circumferential groove 822b sized to
engage the holding member 806b.
[0116] The holding member 806b has a tubular guide portion 824b
(see also FIG. 9) sized to slidingly engage the rod 182b and an
attached flange 826b with a cut-out 828b (FIG. 12F) shaped to
receive the groove 822b of the bearing 802b. Side walls of the
groove 822b help minimize any possible lateral movement of the
barbell 99. A first side 830b of the flange 826b has a catch 832b
that can be pivoted over the cut-out 828b and into contact with an
opposite second side 834b (FIG. 12E). A lever 836b is pivotably
connected to the second side 834b. The lever 836b has a pivoting
bail 838b sized to receive an end of the catch 832b.
[0117] When the barbell 99 is inserted in the cut-out 828b, the
catch 832b is pivoted to the second side, the bail 838b is placed
over the catch 832c, and the lever 836b is pivoted downwardly to
secure the barbell 99 to the holding member 806b.
[0118] The hook 808b has an upper engaging tip 841b and a lower end
843b with an opening 845b. The opening 845b has parallel flat sides
847b (FIG. 12F) sized to engage the flat surfaces 816b of the inner
race 812b. A collar 849b is attached to one end of the body of the
hook at one side of the opening 845b, and can be pivoted to enclose
to the opposite side of the opening 845b and secured in place with
a pin 851b (see, e.g., FIG. 12G) to secure the hook 808b to the
inner race 812b.
[0119] To reposition the holders 180a, 180b, the barbell 99 with
the bearings 802a, 802b and hooks 808a, 808b is removed from the
holding members 806a, 806b, the holding members are pivoted 180
degrees around the respective rods 182a, 182b (to face the interior
of the safety cage), and the barbell 99 is replaced within the
holding members.
[0120] As indicated above, the barbell 99 in most embodiments is
releasably secured to allow use of the barbell on its own, i.e.,
separate from any Smith machine guiding structure, such as, e.g.,
in traditional free weight exercises. For such use, it may be
possible, although not necessary, to remove some or all of the
components, e.g., the hooks and/or the collars, from the barbell,
or these components may remain fixed to the barbell 99.
[0121] In other embodiments, the ability to readily remove the
barbell from the Smith machine guiding structure, e.g., quickly and
without the use of tools, may be optional. For example, removal of
the barbell may not be required to reposition the frame system in a
compact position for storage in some implementations. If so, the
barbell can be attached to the holders in other ways that do not
necessarily provide for its ready release. In these embodiments,
the hooks may be attached by welding. In still other embodiments,
there may be no hooks.
Smith Machine Safety Cage System With Folding Sides
[0122] As shown in FIGS. 10, 11A, 11B and 13, a safety cage system
210 has front uprights fitted with a Smith machine mechanism
(similar to the embodiment of FIGS. 8 and 9) and folding safety
sides (similar to the embodiments of FIGS. 1-7D).
[0123] The construction and operation of the safety cage system 210
are the same as for respective similar features of the safety cage
systems 10 and 110 described above.
[0124] The safety cage 212 of the system 210 is configured from its
open position (as shown, e.g., in FIG. 10) to its compact position
(as shown in FIG. 13) by: (1) disconnecting the ends of the curved
upper lateral member 222 from the front uprights 234a, 234b; (2)
pivoting the curved upper lateral member 222/upper lateral member
221 downward about a pivot 221a against the rear frame member 214;
(3) releasing the locking pivots 236a, 236b; (4) pivoting the right
side frame member 216b against the pivoted members 222, 221; and
(5) pivoting the left side frame member 216a against the pivoted
right side frame member 216b.
Safety Cage System With Folding Sides And Aligned Pivots
[0125] As shown in FIGS. 14 and 15, a system 310 has a safety cage
312 with folding sides, but the pivots are aligned along a common
axis B. The sides have extension portions of unequal length that
allow the sides to be folded flat to configure the safety cage 312
in a compact position.
[0126] A left side frame member 316a has extension portions 317a
extending approximately perpendicular from upper lateral member
330a and lower lateral member 332a. The upper and lower extension
portions 317a are joined by an upright 320a'. The pivots 336a, 338a
are positioned at the junctions between the respective extension
portions 317a and the left side of the rear frame member 314.
[0127] A right side frame member 316b is similar, except the right
side extension portions 317b are shorter than the left side
extension portions 317a. The different lengths of the extension
portions 317a, 317b allow the right side frame member 316b to be
folded flat against the rear frame member 314, and the left side
frame member 316a to be folded flat against the right side frame
member 316b.
[0128] In another system 410, the pivots of a safety cage 412 with
folding sides are also aligned along the axis B, as shown in FIGS.
16A-16E. In the system 410, however, the right side extension
portions 417b are longer than the left side extension portions 417a
(see FIG. 16C), such that the left side frame member 416a is folded
flat against the rear frame member 414 and the right side frame
member 416b is folded flat against the left side frame member 416a,
to configure the safety cage 412 in a compact position (see FIG.
16E).
[0129] In the system 410, the uprights 420a, 420b are round (see
FIG. 16D, which shows an enlarged view of the upper right pivot
436b), and the pivots 436a, 436b, 438a, 438b are sleeves 485 sized
slightly larger than the uprights 420a, 420b, thus creating a
bearing arrangement.
Safety Cage System With Folding And Telescoping Sides
[0130] As shown in FIGS. 17-22, a system 510 has a safety cage 512
with sides that pivot as well as telescope. The pivots in the
system 510 are also aligned along the axis B. In the compact
position, however, the sides do not overlap, but rather lie in the
same vertical plane.
[0131] Referring to FIG. 20, each of the pivots 536a, 536b, 538a,
538b is a joint 590 having a hinge 591 with one portion attached
(e.g., by welds or fasteners) to a sleeve 593. The other portion of
the hinge 591 is attached to the rear frame member 514, thus
allowing the joint 590 to pivot relative to the rear frame member
514.
[0132] The sleeves 593 are sized to slidingly receive the
respective lateral members 530a, 530b, 532a and 532b, thus allowing
these members to be telescoped relative to the joints 590.
[0133] To configure the safety cage 512 in a compact position: (1)
the side frame members 516a, 516b are urged toward the rear frame
member 514, thus causing the lateral members 530a, 530b, 532a and
532b to telescope or slide through the respective joints 590 (see
FIG. 22); and (2) when the lateral members 530a, 530b, 532a and
532b have been slid approximately halfway through the joints 590
(see FIGS. 19 and 22), the side frame members 516a, 516b are
pivoted towards the rear frame member 514 (see FIG. 21).
Safety Cage System With Removable Sides
[0134] As shown in FIGS. 23A-25, a system 610 has a safety cage 612
with sides that can be readily removed, and the rear frame member
has elements that receive and hold the sides when the safety cage
612 is configured in its compact position.
[0135] In the system 610, the rear frame member 614 has a saddle
694 attached at adjacent each upper and lower end of each upright
620a, 620b. Referring to FIG. 23B, each saddle 694 has a channel
695 dimensioned to receive the respective lateral members 630a,
630b, 632a, 632b when the safety cage is configured for use.
Notches 696 in sides of each channel 695 define a space for
receiving the lateral members. The notches 696 in the right side
channels 695 are positioned closer to the rear frame member 614
than the notches 696 in the left side channels 695.
[0136] To configure the safety cage 612 in a compact position, (1)
the right side frame member 616b is removed from the channels 695
of the respective saddles 694 and repositioned in the notches 696
of these channels to lie adjacent and approximately parallel to the
rear frame member 614; (2) similarly, the left side frame member
616a is removed from the channels 695 in the other saddles 694, and
positioned in the notches 696 to lie adjacent and approximately
parallel to the right side frame member 616b (see FIGS. 24 and
25).
[0137] As shown in the figures, the side frame members 616a, 616b
may be pinned, clamped or otherwise secured when the safety cage
612 is configured for use or in its compact position.
Additional Configurations
[0138] In FIGS. 12A and 12B, the frame system 710 with Smith
machine functionality is shown with the barbell positioned on the
outer side of the cage. As noted above and as shown in FIGS. 31-33,
the holders for the barbell can be positioned so that the barbell
is releasably secured on an inside of the frame system.
[0139] FIG. 31 is a front perspective view of a frame system 912
with a rear frame member 914 and folding side frame members 916a,
916b in which the barbell 99 is shown positioned on an inner side,
the barbell 99 being shown without weights. FIG. 32 is a rear
perspective view similar to FIG. 31. FIG. 33 is a plan view of the
frame system 912 showing a view of the expanded frame position with
the barbell (together with added plates) in its releasably secured
position and as configured to be on an inner side of the uprights
934a, 934b. For comparison, FIG. 34 is a plan view similar to FIG.
33, except showing the barbell 99 as it would appear when
configured for positioning on an outer side of the uprights 934a,
934b.
[0140] FIGS. 35-40 show another frame system 1012 in which the side
frame members 1016a, 1016b have so-called "gun rack" portions
1017a, 1017b, each with a series of projecting fingers 1019 and
alternating cut-outs 1021. The projecting fingers 1019 are shaped
to receive hooks 1023 attached to the barbell. The gun rack
portions 1017a, 1017b may be separate pieces attached to the side
frame members, or the side frame members may be formed with the gun
rack portions. With the gun rack portions, the upright members need
not have openings. If desired, the hooks 1023 can be fitted with
rollers at their ends to facilitate smooth engagement and
disengagement from the fingers 1019. In a simplified construction
(not shown), the barbell is placed directly within appropriately
shaped cut-out portions, without the need for the hooks 1023.
[0141] FIG. 36 shows the frame system 1012, having a rear frame
member 1014, after the barbell has been released from its securing
holders, and the side frame members 1016a, 1016b have been angled
inwardly towards each other. FIGS. 37, 38 and 39 are perspective,
front and top views, respectively, showing the frame system 1012
with the barbell removed and the side frame members positioned for
storage. FIG. 40 is a perspective view showing the frame system
1012 with the barbell removed and the side frame members 1016a,
1016b angled away from each other.
[0142] Smith machine functionality in a frame system reconfigurable
to a compact format for storage can be achieved with folding side
frame members that are pivotably attached to the rear frame member,
such as is shown in FIGS. 10, 11A, 11B, 12A, 12B, 13 and 31-40, and
with side frame members that telescope relative to the rear frame
member, such as is shown, e.g., in FIGS. 8 and 9. Other frame
system styles capable of a compact format can also be configured
with Smith machine functionality, such as side frame members with
hinged lateral members of the side frame members, e.g. as shown in
FIGS. 41-43, and sliding lateral members of the rear and/or side
frame members, e.g., as shown in FIGS. 44-47.
[0143] FIG. 41 shows a frame system 1112 having a rear frame member
1114, with hinged lateral members of the side frame members 1116a,
1116b in its expanded position. FIG. 42 shows the frame system 1112
being repositioned from the expanded position to the compact
position, which is shown in FIG. 43. As can be seen from the
figures, the barbell 99 need not be removed to position the frame
system 1112 in its compact position. If desired, the barbell 99 can
be fixed to the holders to prevent easy removal of the barbell,
i.e., without the use of tools, which may be advantageous in some
situations, e.g., for safety and/or for security.
[0144] FIG. 44 shows a frame system 1212 with translating lateral
members of the rear frame member 1214, which allow the side frame
members 1216a, 1216b to translate towards each other to reposition
the frame system in the compact position shown in FIG. 45. FIG. 46
shows a frame system 1312, having a rear frame member 1314, with
translating lateral members of the side frame members 1316a, 1316b.
FIG. 47 shows a frame system 1412 with translating lateral members
in both the rear frame member 1414 and the side frame members
1416a, 1416b. The translating members may simply slide, or they may
be fitted with small rollers that roll while the members are moved
relative to each other.
[0145] In some implementations, e.g., as best shown in FIG. 5B,
each pivoting side frame member has a locking pin or member (e.g.,
the left locking pin 43a) that is positioned closer to the end of
the side frame member (e.g., the left side frame member 16a) than
the pivot pin or member (e.g., the left pivot pin 41a). In other
implementations, the pivot pin is positioned closer to the end of
the side frame member than the locking pin.
[0146] For example, referring to FIG. 33, the left pivot pin 941a
is positioned closer to the end of the left side frame members 916a
than the left locking pin 943a. The right side is configured in a
similar manner.
[0147] In addition to the locking pin 43a shown in FIGS. 5C and 5D,
which is vertically or axially inserted into and removed from
aligned openings in the side frame member 16a and the plate 37a,
other types of locking members can be used. For example, as shown
in FIG. 48, the locking pin 943a is moved generally horizontally
into and out of engagement with openings in the frame member 916a
and plate 937a. The locking pin 943a can be biased to retain it in
its locked position, e.g., such as by a spring 989 connected
between the pivot pin 941a and the locking pin 943a, as shown in
FIGS. 48 and 49.
[0148] The locking pins may be actuated, i.e., pulled against the
bias of the spring and out of engagement with the slot or slots in
the plate(s) to allow the frame members to be pivoted about the
pivot pins, in any suitable way. For example, the locking pin 943a
may have an attached handle 991 (as shown, e.g., in FIGS. 35 and
48) or an attached lever 993 (FIG. 49).
Smith Machine With Dynamic Lifting Axis
[0149] In the embodiments described above, the implementation of
Smith machine functionality is described for systems with a
generally static lifting axis (or matched pair of lifting axes).
The lifting axis is defined as the direction along which the load
is constrained to move during a lift. A static lifting axis remains
substantially stationary during lifting. As one example, referring
to FIG. 8, the static lifting axis as defined by the rods 182a,
182b is substantially vertical. Although not shown, it is also
possible to have the static lifting axis positioned at a slight
angle (e.g., up to about 15 degrees from vertical).
[0150] Providing a system with Smith machine functionality in which
the lifting axis is dynamic rather than fixed widens the range of
available exercises and allows the system to accommodate users over
greater ranges in size, strength and flexibility. One example of a
system with Smith machine functionality and having a dynamic
lifting axis is U.S. Pat. No. 5,215,510. This patent shows vertical
guiding members (defining a primary vertical lifting axis) that are
free to translate at their ends along horizontal guiding members
(defining a secondary horizontal lifting axis). During a lift, the
axis is dynamic, i.e., the guiding member that defines the axis is
allowed to move and is not constrained to be stationary. Although
this configuration provides some of the advantages of a dynamic
lifting axis, the lifting axes are strictly vertical and strictly
horizontal, both ends of the vertical guiding members are
constrained, and the system cannot be reconfigured for compact
storage.
[0151] According to the new approaches described herein, Smith
machine functionality with dynamic lifting axes is achieved using
upright guide members having one end that is free to translate and
an opposite end that is fixed from translating. These upright guide
members can be used when the frame system is positioned with its
side frame members extending perpendicular to the rear frame
member, or with the side frame members extending at angles other
than 90 degrees. Also, the frame system can be reconfigured to a
compact position.
[0152] The end of each guide member that is fixed from translating
may be pivotable in one, two or three directions. For example, as
shown in the side views of a frame system 5000 illustrated in FIGS.
50A, 50B and 50C, the lower ends of the guide members may be
pivotably connected to the frame system, thus allowing the free
upper ends to translate. Although not shown, it would also be
possible to have the upper ends of the guide members pivotably
connected and to leave the lower ends free to translate.
[0153] FIG. 50A shows the guide member pivoted rearwardly, FIG. 50B
shows the guide member in a generally vertical position, and FIG.
50C shows the guide member pivoted rearwardly. The range over which
the upper ends of the guide members may translate can be limited as
desired, e.g., by using stops or openings through which the guide
members project, as is described below in more detail.
[0154] As indicated, the lower ends of the guide members can be
fixed from translating, but can be pivotable in more than one
direction, i.e., pivotable about multiple mutually perpendicular
axes. During lifting, this additional freedom of motion may require
use of secondary muscles to stabilize the movement that otherwise
may not be challenged in use of a typical Smith machine, yet the
guide members still provide the safety of guided movement of the
barbell. It bears noting that this overall additional freedom of
motion is produced even when each of the various axes of rotation
provides only slight freedom of rotation.
[0155] In the embodiment of FIGS. 50A, 50B and 50C, each guide
member is restricted to pivoting in a single plane, i.e., pivoting
in a vertical plane parallel to the respective side frame members.
In the embodiment of FIGS. 51-58, however, the lower ends of the
guide members are coupled to the frame by a "multiply pivotable
connection," i.e., a connection that allows pivoting about at least
two mutually perpendicular axes.
[0156] FIG. 51 is a perspective view of a frame system 5100 showing
guide members 5102a, 5102b in a substantially vertical position
with their upper ends protruding through guide openings 5104a,
5104b and their lower ends 5106a, 5106b coupled at multiply
pivotable connections.
[0157] FIG. 52 is a detailed view of an exemplary multiply
pivotable connection 5108a at the lower left side of the frame
system. In this specific example, the multiply pivotable connection
5108a provides for rotation about three mutually perpendicular
axes, i.e. the X, Y and Z axes as shown. The range of available
rotation, e.g., before mechanical interference occurs, may be
limited, but even a small range of a few degrees is sufficient to
cause the user to experience forces in multiple directions
simultaneously.
[0158] FIG. 53 is a detailed view of the upper left side of the
frame system showing the guide member 5102a protruding through the
guide opening 5104a in a guide plate 5110a. As can be seen in FIG.
53, the guide opening 5104a can be dimensioned in the forward and
rearward and in the side to side directions to allow as much
movement of the guide member 5102a as is desired. As illustrated,
the size of the guide openings has been exaggerated for clarity. In
practice, sufficient translation of the upper ends of the guide
members may be achieved with guide openings that are only minimally
larger than the guide members.
[0159] FIG. 54 is a top view of the upper right corner of the frame
system. As shown in FIG. 54, the guide plate 5110a can also be
shaped with cutouts 5112a at either end that tend to keep the guide
member in a vertical orientation when it is positioned at either
end.
[0160] With a multiply pivotable connection at one end of each
guide member, the resulting linkage comprised of the left guide
member linked to the barbell via a standard holder, and the other
end of the barbell linked to the right guide member via a standard
holder, causes one degree of freedom to be lost or at least reduced
because the standard holders are restricted to translation along
the guide members and rotation about the guide members. The
resulting configuration may still be advantageous for some
situations. In other situations, however, it is desirable to
maintain the additional freedom of rotation provided by the
multiply pivotable connection by modifying the barbell holders.
[0161] According to one approach, the holders can be modified to
provide additional freedom of movement as shown in FIGS. 58-60,
which show the barbell 99 being kept level while the guide members
5102a, 5102b are angled to the left, kept vertical or angled to the
right. As one example, holders 5114a, 5114b as best shown in FIGS.
55-57 can have respective pivoting joints 5116a, 5116b. The
pivoting joints 5116a, 5116b allow portions of the holder to pivot
relative to each other about an axis normal to the guide member so
that the user must strive to keep the barbell 99 level during the
lift even as the guide members 5102a, 5102b are free to move in the
side to side and forward to rearward directions.
[0162] Overall, the resulting linkage still serves to assist the
user in guiding the barbell during lifting. With the appropriate
modifications, such as the use of range limiting structures and
adjustments to the fit between the components of the linkage, the
degree of guiding assistance provided to the user can be varied
between slightly less assistance than a standard Smith machine to
slightly greater assistance than a free lift.
[0163] Although the guide plates 5110a, 5110b are shown extending
to the outside of the frame member (see, e.g., FIG. 51), they can
of course be mounted to extend to the inside (not shown). Also, it
is possible to have the guide members 5102a, 5102b extend in
generally the same plane of the side frame members, with
appropriate openings in the safety bars, as is shown for a frame
system 6100 illustrated in FIG. 61.
Multi-Position Carriage System
[0164] The multi-position carriage system 748 shown in FIGS. 28A-29
is another cable supported rolling weight arrangement similar to
the carriage 50 described above in connection with FIG. 1. With the
system 748, the position of the carriage 750 can be selectively set
along the length of the upper lateral members 30a, 30b. As a
result, the point at which the cable extends downwardly can be
moved to a position that is more centrally located within the
safety cage 12.
[0165] As shown in FIGS. 28A-29, the carriage system 748 includes
the carriage 750, the upright member 752 over which the carriage
travels, and a lateral member 754 pivotably attached to the upper
end of the upright, together with the associated cable and
hardware. In operation, the lateral member 754 is extended as shown
in FIG. 28A, and the system 748 is secured in place (e.g., with
pins), such as in the position shown in FIG. 29. The carriage 750
can then be loaded with weights and used similar to the carriage
50.
[0166] The system 748 is removable, e.g., when not in use or for
storage, and the lateral member 754 can be pivoted against the
upright member, as shown in FIG. 28B.
[0167] The carriage system 748 may be available as an optional
accessory for a safety cage that is not fitted with the carriage
50.
Optional Accessories
[0168] As shown, e.g., in FIG. 1, any of the various systems
described above may include an optional overhead bar 48 that is
coupled at its ends to the upper lateral members 30a and 30b,
respectively. The overhead bar 48 may be used, e.g., to perform
chin-up and/or pull-up exercises.
[0169] As shown in FIGS. 6A and 6B, the described systems may
include optional dip handles 71a, 71b removably attached to the
front uprights 34a, 34b, respectively. These handles may be grasped
by the user to perform, e.g., dip exercises. The handles 71a, 71b
may be attached to extend toward the inside of the safety cage 12
(FIG. 6A) or toward the outside of the safety cage (FIG. 6B).
[0170] Referring to FIG. 1, a pair of barbell holders 73a, 73b can
be removably attached to the rear uprights 20a, 20b, respectively,
to face the interior of the safety cage, or attached to the front
uprights 34a, 34b to face the interior of the cage or away from the
interior (FIG. 2).
[0171] A pair of foot loops 98 can be attached to the safety cage
to assist a user in performing, e.g., sit-up exercises. As shown in
FIG. 1, the foot loops can be attached to the lower lateral member
32a.
[0172] As shown in FIG. 4, the system 10 may include one or more
lanyards 151 suited for securing the folded safety cage 12 to a
nearby structure, e.g., a wall, to prevent it from tipping over if
jarred.
[0173] As shown in FIG. 10, the bench 40 may be fitted with an
optional rear foot 88 instead of being pivotably attached to the
rear frame member 14. Together with the front foot 87, the rear
foot 88 allows the bench 40 to be used independent of the safety
cage 12, e.g., for exercises that a user prefers to perform outside
of the safety cage 12, while retaining the ability to pivot the
rear portion 42 relative to horizontal.
[0174] As shown in FIG. 5B, the opposing edges of the rear back
portion 42 and the front seat portion 44 may have respective shaped
sections 90 and 91. The sections 90 and 91 are shaped as shown to
provide openings within which a user can position his legs while
standing to secure his stance while performing certain exercises,
e.g., military press, bicep curls, etc.
[0175] As shown in FIGS. 26A, 26B and 26C, a modified bench 840 can
be used in place of the bench 40. The modified bench 840 has a
pivoting rear portion 842, a front portion 844 and a supporting
frame 846. The rear portion 842 can be pivoted upwardly (FIG. 26A),
positioned horizontally (FIG. 26B) or pivoted downwardly (FIG.
26C). The bench 840 can be used as a stand-alone (FIGS. 26A, 26B
and 26C) or as an integrated component of any of the safety cage
systems.
[0176] FIG. 29 shows the modified bench 840 attached to a rear
lateral member of the system 10 with the rear portion 842 pivoted
to a nearly vertical position. FIG. 30 is similar to FIG. 29,
except the modified bench has been pivoted rearwardly to free space
within the safety cage 12 and the rear portion 842 is positioned in
approximately the same plane as the front portion 844.
[0177] As shown in FIGS. 27A, 27B and 27C, the systems may include
an arm rest 108 used, e.g., in performing arm exercises, such as
curls. The arm rest 108 has a pad 109a mounted to an upright 109b
that is supported by a foot 109c. A mounting portion 109d is
attached to the upright 109b. The mounting portion 109d can be
connected to the bench by inserting it into the open end of the
frame member of the bench and securing it with a pin.
[0178] Referring to FIG. 1, the weight lifting system described
above can be fitted with an integrated audio and/or visual system
101 (e.g., a stereo, TV and/or a computer) with a main unit 103 and
loud speakers 105. The system 101 can be used to provide
entertainment while exercising (e.g., by radio, TV, CD, DVD, etc.).
If the system 101 includes a computer, it may include a dedicated
application, e.g., to record exercise date (e.g., user, date, time,
exercise, repetitions, sets, etc.), calculate certain parameters
(e.g., total weight lifted, duration of workout, % of maximum lift,
etc.) and/or allow the user to view data from past workouts.
[0179] Referring again to FIG. 1, the systems described above can
also have an integrated beverage dispenser or beverage holder 107
for providing a source of liquid to the user during exercise. The
holder 107 can be mounted to the safety cage 12 at any convenient
location, such as an outer side of the right rear upright 20b as
shown.
General Construction
[0180] In preferred embodiments, the various components of the
system are made of steel or other suitable materials. As can be
seen in the drawings, the system components can be made from
square, rectangular and round tubing (e.g., the upright, rear
lateral and bench frame members), as well as solid bar stock (e.g.,
the lateral members and safety sides of the side frame members), as
appropriate. The edges of square and rectangular pieces may be
rounded for convenience, safety and improved aesthetics.
[0181] As also seen in the drawings, many of the joints between the
various rigidly connected members are formed with a pair of
overlying gusset plates and through bolts (see, e.g., gusset plates
108 and bolts 109 in FIG. 1). Thus, the system can be at least
partially disassembled, for shipping, transport, etc. As known to
those of ordinary skill in the art, welding or other forms of
attachment may also be used.
[0182] Having illustrated and described the principles of my
invention with reference to several preferred embodiments, it
should be apparent to those of ordinary skill in the art that the
invention may be modified in arrangement and detail without
departing from such principles.
