DETAILED DESCRIPTION OF EMBODIMENTS
[0022] FIG. 1 shows a functional trainer or multi-exercise function
apparatus 10 according to the invention comprising a pair of right
20 and left 30 arms which are both pivotable respectively around
axes 42, 40 and both rotatable respectively around axes 50 and 60.
As shown axes 40 and 42 are collinear/coaxial but do not
necessarily need to be collinear or coaxial. The apparatus has a
front face 70 in front of which the user normally stands or is
otherwise positioned when using the apparatus 10 so as to have
manual access to the handles 80, 90 held at the distal ends 100,
110 of each arm 20, 30 respectively. As shown in FIG. 1, the arms
20, 30 extend forwardly from the front face 70 from a pivot end
120, 130 which is/are proximal to the front face 70 to the distal
ends 100, 110 which are forwardly extending relative to the face
70; and the arms 20, 30 are rotatable in semi-circular arcs 140,
150 around axes 50, 60 which project forwardly of the frontal face
70. As can be readily imagined when the arms are pivoted in a
position out of vertical as shown in FIG. 1 for example, the arms
20, 30 will travel through a half conical path when rotated fully
through the semicircular arcs 140, 150. The upright frame elements,
160, 170, FIG. 6, on which the arms 20, 30 are rotatably mounted
and the cover 180 and other components are generally mounted are
themselves mounted or rigidly attached to leg supports 200, 210
which are seated on the ground as shown.
[0023] As shown in FIG. 2, each arm 20, 30 may be rotated around
its rotation axis 50, 60 into locked rotated positions/increments.
As shown in FIG. 2, arm 30 is lockable into rotated positions 149
through 159 which are in 20 degree arcuate increments along the
entire 180 degree arcuate travel 150 of arm 30. The arms may he
locked into any incremental arcuate positions and such locked
positions may be of any selected incremental size or degree and may
be incrementally the same or different from each other. In the
embodiment shown, the locked positions are enabled by bushings 270
which are stationarily attached to frame uprights 160, 170 having
incrementally spaced apertures 149a, 151a et seq., FIG. 1, which
correspond to angular positions 149-159, FIG. 2 (apertures
corresponding to positions 153-159 not labeled/shown in FIG. 1). A
pin 181, FIGS. 1, 3, 4, which is spring 282 loaded and mounted on
rotatable axle flange 300, FIGS. 1, 4, is manually insertable into
any of the apertures (e.g. 149a, 151a) in the flanged portion 270
of cylindrical bushing 272, the apertures in flange 270
corresponding to positions 149-159, by manually pulling backwardly
on the head of the pin 181, releasing the pin and allowing the pin
to be spring 282 force inserted into a selected aperture thus
locking the rotation position of the rotatable axle 301 around axis
50 into a selected angular position. As shown in FIG. 4, the
forwardly extending arm 20 with end portion 24 is pivotably
attached at pivot axis 42 to bracket 23 which is in turn fixedly
attached to or integrally formed together with the flange portion
300 of the rotatable axle 301. Axle 301 is rotatably mounted within
fixedly attached bushing 272 by any conventional mechanism, e.g. by
a rotation enabling bearing 25 interposed between the outer surface
of axle 301 and the inner surface of fixedly mounted bushing 272,
FIG. 4. The cylindrically shaped axle 301 is thus attached to arm
20 via bracket 23 as shown ill FIG. 5 and arm 20 is thus rotatable
around axis 50 by rotation of axle 301 within bushing 272.
[0024] As shown in FIGS. 3-5, arm 20 is pivotable and lockable into
incremental arcs around pivot axis 42, e.g. into incremental
angular positions 330, 331, 332, FIG. 3, which correspond to the
locking of pin 310, FIG. 5, into incremental angular apertures 320,
321, 322 As can be readily imagined, the number, size and degree of
the incremental arcuate positions and apertures provided for
pivoting movement of arms 20, 30 can be varied and selected to be
of any desired value. A user can change the pivot position of an
arm 240, 250 by pulling outwardly on the exposed head of pill 310
to disengage the inner end of the pin 310 from an aperture, 320,
321, 322, manually pivoting an arm around an axis 40 or 42 to a
position where the pin is in axial alignment with a desired
aperture 320, 321, 322 and releasing the head of the pin 310
allowing the spring 311, FIG. 5, to snap the tip end of the pin
into engagement within the desired pivot position aperture.
Preferably the weight of the arms 20, 30 is selected to allow the
user to readily pivot the arms 20, 30 to any desired pivot position
around axes 40, 42 and to further facilitate such manual pivoting,
a pneumatic or hydraulic cylinder, shock absorber or the like 350,
FIG. 3 is provided between mounting bracket 23 and arm 20, 30 so as
to counterbalance or at least lessen any torque force exerted by
the weight of an arm 20, 30 around the pivot axes 40, 42.
[0025] As shown by FIGS. 1-6, arms 20, 30 can be rotated and
pivoted about axes 50, 60 and 40, 42 such that the distal ends 100,
110 of the arms and their associated handles 80, 90 can be
positioned closer to or further away from the face 70 of the
apparatus 10 in a wide variety of upward, sideward and downward
positions thus enabling the user to self create or choose an
exercise for any desired muscle or muscle group, e.g. a pull down
exercise where the handles are positioned as shown in FIG. 1, or a
pull up exercise when the arms are rotated to a downward position,
or a rowing or pull in exercise when the arms are pivoted to a more
horizontally disposed position. As can be readily imagined, the
arms 20, 30 can be positioned to virtually limitless positions for
creating an exercise of the user's choice/selection. The handles
80, 90 can be engaged by the user's foot/feet, head, elbow, etc.
when positioned appropriately relative to the position of the
user's body on the ground or other implement such as a bench on
which the user may sit or lie to perform a chest press or sit up or
leg or calf press or other exercise as the user may select.
[0026] Incidental rotation of the arms 20, 30 when residing in any
given position of rotation is controlled by a safety tension
mechanism. As shown in the embodiments in FIGS. 1-6, the rotation
axle 301 is provided with a flange plate 261, FIGS. 2, 4, to which
is rotatably attached a link 260 which is attached to a cable 251
which is routed around a pulley 252, FIG. 2, which is attached to a
stretchable spring 250 which is connected to the frame member 165.
When an arm is in a zero rotation torque position, position 149,
such as when the arms are in the positions shown in FIG. 1, the
flange plate 261 is not rotated around axis 60 and spring or
tension member 240 is in a minimum stretch or tension state. In the
minimum stretch state, e.g. as shown in FIG. 2 with respect to
spring 240, the spring is nevertheless stretched to a certain
degree and under tension in the minimum zero torque position of
plate 261 so that the arm 20 is held in a steady state position
under the tension of tension member 240 or 250 as the case may be.
When an arm is rotated out of the zero torque position, e.g. in
position of arm 30 shown in FIG. 2, the tension member 250 is
further stretched and the tension increased somewhat relative to
the minimum stretch position to account for the added rotational
torque force exerted by the weight of an arm 20, 30 through axle
301 to plate 261. Preferably the added tension which the tension
member 240, 250 undergoes throughout the entirety of the complete
arc of rotation of plate 261 is small relative to the maximum
tension which the tension member is capable of withstanding or
exerting. Preferably the tension which the tension member 240, 250
exerts through to the plate 261 against rotation of an arm 20, 30
in any given position of rotation of plate 261 along arc 150 is
less than about ten percent of the maximum tension or upper tension
limit value of the tension member. In any event, when an arm is
rotated to any position along arc 150 and in any pivot position
along arc 333, the tension exerted by the tension member 240, 250
is sufficient to hold the arm in whatever rotated and pivoted
position in which it may be residing at the moment, i.e. the weight
of the arm 20, 30 and the rotation torque force which the arm may
exert on axle 301 in any given rotation and pivot position, is
counterbalanced by the opposing tension in tension member 240, 250
such that arm is held in such position and will not drift
downwardly or upwardly in the absence of the user's applying a
manual or other torque rotation force to an arm. Preferably a user
may easily and smoothly rotate an arm to any desired position of
rotation against the rotation controlling tension force exerted by
the tension member.
[0027] FIG. 6 shows a cabling arrangement for interconnecting the
handles 80, 90 to the weight resistance mechanism 380. As shown, a
single flexible cable 390 is connected between the handles 80, 90,
the cable 390 being routed through the arms 20, 30 and through/past
the pivot positions where the pivot axes 40, 42 are located. The
single cable 390 is further routed around a series of pulleys
391-399 which are all mounted such that when either handle 80, 90
is pulled outwardly from the distal ends of the arms, the cable 390
necessarily pulls downwardly on pulley 395 which is connected to a
second cable 410 which is routed around pulleys 411, 412 and
interconnected at its distal end 415 to the frame member 178. As
pulley 395 is pulled downwardly, pulley 412 is pulled upwardly.
Pulley 412 is connected to the weight resistance mechanism 380 and,
when pulley 412 is pulled upwardly, the weight resistance mechanism
380 is pulled upwardly along with pulley 412 via the weight bearing
rod 287, FIG. 2, thus creating the opposing force to the user's
pulling on one or both of the handles. As can be readily imagined
and shown in FIG. 7, both handles can be pulled outwardly at the
same time, both such pulling motions, 425, 426 resulting in a
simultaneous downward pulling 418, 419 on pulley 395 and
concomitant lifting 417 of pulley 412. Similarly, pulling 435, FIG.
8, on a single handle results in downward pulling force 421 on
pulley 395. As shown, all of the routing pulleys for the single
cable 390 which extend between the handles, i.e. s pulleys 391,
392, 393, 394 and 396, 397, 398, 399 and the routing pulley 411 are
connected or anchored to a stationary component of the apparatus.
Pulleys 395 and 412 are floating enabling upward pulling of the
weight resistance mechanism 380.
[0028] As shown in FIGS. 7, 8 the terminal ends of the cable 390
are provided with stops 500 attached to cable 390. Follower pulleys
420 are also mounted on the ends 100, 110 of arms 20, 30 so as to
cooperate with pulleys 391 to provide an interference mechanism for
stops 500 thus limiting the backward movement of the terminal ends
of cable 390 (to which the handles 80, 90 are attached) beyond the
position of pulleys 391, 420 and 399, 420.
[0029] The weight resistance mechanism 380 shown in the embodiment
of the Figures comprises a stack of incremental weights any
selected number of which a user can interconnect to pulley 412
before beginning an exercise, e.g. by inserting a pin through a
lateral aperture which is provided in each of the incremental
weights in tile stack and continuing through a complementarily
aligned aperture provided in the rod 287, FIG. 2, for each
incremental weight, the weight bearing rod 287 being interconnected
to pulley 412. Other weight resistance mechanisms can be provided
such as free weights, a high tension springs, a high tension
stretch or compression member, a force resistance rotating
mechanism, a container fillable with a selected amount of fluid or
the like.
[0030] The horizontal foot supports 210, 200 are rigidly connected
to the upright frame supports 160, 170 at a generally right angle
and have a length extending from the point of connection 515, FIG.
6 selected to safely oppose any rotating torque force around the
point of connection 515 that might tend to tip the upright supports
160, 170 over.
