[0018] FIG. 1 is an exploded view of one embodiment of a twister
exercise device, which is designated generally by reference numeral
10. The twister 10 is capable of providing combination pivotal and
vertical up-and-down exercise motions. In the illustrated
embodiment, the twister 10 generally includes a base unit 12, a
foot support 14, a resilient member 16, a biasing assembly 18, and
a handle assembly 20.
[0019] The base unit 12 is configured to be anchored to or
supported by a floor. In the illustrated embodiment, the base unit
12 includes a base frame 22 and a base cover 24 mounted to cover
the base frame 22. As illustrated, the base frame 22 has a
streamlined outer profile with four protrusions. It is to be
understood that this is for the purposes of illustration only and
the base frame 22 could be of any suitable shape.
[0020] Also referring to FIG. 2, the base frame 22 is generally
cross-shaped formed by two support beams 26. Each support beam 26
has two mounting slots 28 defined on opposite sides of the
intersection, respectively. Each mounting slot 28 has a narrow
portion and a wide portion in communication with each other. The
mounting slots 28 are used to mount the biasing assembly 18 as
described below.
[0021] A shaft 30 extends perpendicularly upward from an
intersection of the two support beams 26. The shaft 30 defines a
pivot axis along its longitudinal axis.
[0022] The foot support 14 is configured to support a user thereon
for performing various exercise activities. In the illustrated
embodiment, the foot support 14 includes a foot support frame 32
and a foot support panel 34. As illustrated, the foot support frame
32 includes two parallel first support beams 36 and one second
support beam 38 traversely connecting the two first support beams
36. A pivot hole 40 is defined through a general middle area of the
traverse second support beam 38. With the shaft 30 received into
the pivot hole 40, the foot support frame 32 is capable of pivoting
about the pivot axis. The foot support panel 34 is fixedly mounted
to and thus supported by the foot support frame 32. As the foot
support frame 32 is pivotable about the pivot axis, the foot
support panel 34 and the entire foot support 14 are thus pivotable
about the pivot axis.
[0023] The foot support panel 34 can be mounted to the foot support
frame 32 in any suitable manner. In the illustrated embodiment, the
foot support panel 34 is fastened to the foot support frame 32 with
fasteners 42. To this end, the support beams 36, 38 of the foot
support frame 32 also define fastening holes 44 therethrough.
Although not illustrated, the foot support panel 34 also has
corresponding fastening structures. However, this particular
mounting manner is for the purposes of illustration only and should
not be regarded as limiting.
[0024] The foot support panel 34 includes one or more, such as, a
pair of side-by-side foot pedal areas 46 formed or provided
thereon. Each of the foot pedal areas 46 has a plurality of
protrusions 48 extending upwardly therefrom, for engaging with and
for massaging the feet of the user. The foot pedal areas 46 and the
protrusions 48 are preferably made of rubber or other soft
materials, for comfortably engaging with the user.
[0025] While the foot support 14 is illustrated as including the
discrete foot support frame 32 and foot support panel 34 together,
it is noted that the foot support 14 may also be formed as a
unitary structure with a foot support frame and a foot support
panel integrated together. Therefore, the foot support frame 32 and
the foot support panel 34 can be either discrete elements or
integrally formed together into a unitary structure.
[0026] In the illustrated embodiment, the twister 10 also includes
an exercise information generating assembly to provide parameters
and information associated with the user exercise activities. The
exercise information generating assembly includes a sensor unit 50
mounted on the foot support frame 32 and a display unit 52 provided
on the foot support panel 34. The sensor unit 50 operates to sense
information associated with the user's exercise activities. The
display unit 52 is electrically connected to the sensor unit 50 to
display the information sensed by the sensor unit 50. To this end,
the parameters or information can be those relating to the weight
of the user, the number and/or speed of twist, and/or the number of
skips. While the exercise information generating assembly is
disposed on the foot support 14 in the illustrated embodiment, it
is to be understood that the exercise information generating
assembly can be disposed on other parts of the twister 10 in
alternative embodiments. For example, at least the display unit 52
could be disposed on a top portion of the handle assembly 20.
[0027] Also referring to FIGS. 3 to 5, in the illustrated
embodiment, the resilient member 16 includes a spring attached
around the shaft 30. The spring 16 is disposed between the base
unit 12, in particular, the base frame 22, and the foot support 14,
in particular, the foot support frame 32. The resilient member or
spring 16 has opposite spring ends 54 and 56 slidable relative to
the base frame 22 and foot support frame 32, respectively.
Therefore, the resilient member or spring 16 resiliently supports
the foot support 14 thereon while permitting the pivotal movement
of the foot support 14. A pair of end plates 58 is disposed between
the spring end 54 and the base frame 12, and between the spring end
56 and the foot support frame 32, respectively. The end plates 58
limit the position of the resilient member 16. As illustrated, the
end plate 58 is circular-shaped. However, it is to be understood
that the end plate 58 could be of another shape as long as it can
provide the functions illustrated above. In the illustrated
embodiment, the end plates 58 are fixed to the foot support frame
32 and the base frame 22, respectively, in any suitable manner, for
example, by welding. While the resilient member 16 is implemented
as a spring in the illustrated embodiment, it is to be understood
that the resilient member 16 could be any suitable resilient
structure as long as it can bias the foot support 14 upward or
resiliently support the foot support 14. A bearing unit 59 is
disposed around the shaft 30 between the spring end 54 and the
bottom end plate 58. The bearing unit 59 includes rollers or balls
therein to reduce friction during pivot movement of the foot
support 14 of the twister 10.
[0028] The biasing assembly 18 is connected between the base unit
12 and the foot support 14 to control the pivotal movement of the
foot support 14. In the illustrated embodiment, the biasing
assembly 18 includes a resistance assembly having a plurality of
resistance cords 60 made of, for example, latex. In the specific
exemplary embodiment as shown, the number of the resistance cables
60 is four. The plurality of resistance cords 60 are evenly
distributed around the shaft 30. The resistance cords 60 are
connected to the base unit 12, in particular, the base frame 22,
and the foot support 14, in particular, the foot support frame 32
in any suitable manner. In the specific embodiment as shown, each
resistance cord 60 has opposite expanded cord ends 62 and 64. As
can be best seen from FIG. 3, the resistance cords 60 are inserted
into the narrow portions of the respective mounting slots 28, with
the expanded ends 62 engaging the base frame 22 around the narrow
portions of the mounting slots 28, and plugs 66 are engaged within
the wide portions of the mounting slots 28. In this way, the cable
cords 62 are secured to the base unit 12, in particular, the base
frame 22. By achieving this, each cable 60 is first inserted
through the wide portion of a corresponding mounting slot 28 and
then slided to the narrow portion, and finally the plug 66 is
inserted into the wide portion of the mounting slot 28. The other
cord ends 64 may be secured in the same or a different manner.
[0029] When a user stands on the foot support 14 to perform a twist
exercise, the user generally twists his/her hip side-to-side to
result in a side-to-side pivotal movement of the foot support 14
about the pivot axis. During this pivotal movement of the foot
support 14, the biasing assembly or resistance assembly 18 applies
a resistance force against the pivot movement of the foot support
14 away from a neutral position of the foot support 14. In other
words, the biasing assembly 18 is arranged to bias the foot support
14 toward the neutral position of the foot support 14. As used in
this disclosure and the appended claims, the term "neutral
position" is intended to mean the position as shown in FIGS. 3 to 5
where no user applies a twist or pivot force on the foot support 14
or no user stands on the foot support 14 doing an exercise. The
side-to-side pivotal movement of the foot support 14 includes the
pivotal movement away from the neutral position in a first or
clockwise direction, the pivotal movement toward the neutral
position in a second or counterclockwise direction, the pivotal
movement away from the neutral position in the second or
counterclockwise direction, and the pivotal movement toward the
neutral position in first or clockwise direction. In other words,
the foot support 14 is pivoted away from or toward the neutral
position during the pivotal movement of the foot support 14. In
this neutral position, as shown in the drawings, the resistance
cords 60 are positioned in parallel with each other and with the
shaft 40.
[0030] Once the foot support 14 is pivoted away from the neutral
position either in the clockwise or counterclockwise direction, for
example, by a user's twist exercise, the biasing member or
resistance assembly 18, through the resistance cords 60 which are
stretched, applies a resistance force against such pivotal
movement. Therefore, the user needs to overcome this resistance
force of the biasing member 18 during the exercise. The pivotal
movement of the foot support 14 usually has a left extreme position
(e.g. when pivoting in the counterclockwise direction) and a right
extreme position (e.g. when pivoting in the clockwise direction)
(not shown) to avoid over-twist by the user. The farther the foot
support 14 is pivoted away from the neutral position, the more
difficult the user would feel to overcome such resistance force.
Therefore, the resistance assembly 18 can also be used to define
these left and right extreme positions where the resistance force
of the resistance assembly 18 increases to a value that the user is
not able to overcome.
[0031] Referring again to FIG. 1, the twister 10 further includes a
resilient outer cover 70. The outer cover 70 is disposed to cover
at least a part of the twister 10. In the illustrated embodiment,
the outer cover 70 is disposed between the base unit 12 and the
foot support 14 to cover elements between the base unit 12 and the
foot support 14. The resilient outer cover 70 is deformable in a
direction parallel to the pivot axis in compliance with the
vertical movement of the foot support 14 along the pivot axis. The
resilient outer cover 70 is also mounted to one of the base unit 12
and the foot support 14 but pivotable relative to the other of the
base unit 12 and the foot support 14 about the pivot axis in
compliance with the pivot movement of the foot support 14 about the
pivot axis.
[0032] In the illustrated embodiment, the outer cover 70 has a
cover body 72 with an upper edge 74 and a lower edge 76. The cover
body 72 is in a form of a corrugated hose and is therefore capable
of extending or retracting in response to the vertical movement of
the foot support 14. The upper edge 74 is movably connected to the
foot support frame 32 to permit the pivotal movement of the foot
support 14 relative to the outer cover 70. In the illustrated
embodiment, the upper edge 74 is mounted to the foot support frame
32 through a bearing structure 77. The bearing structure 77
includes a lower retainer sheet 78, a plurality of balls 79, a ball
fixing ring 80, an upper retainer sheet 81, and a retainer ring 82.
Also referring to FIG. 6, the lower retainer sheet 78 is fixed to
the upper edge 74 of the outer cover 70 in any suitable manner, for
example, with self-plugging rivets. The upper retainer sheet 81 is
fixed to the foot support frame 32 in any suitable manner. The ball
fixing ring 80 has holes receiving the balls 79 therethrough. The
combination of the ball fixing ring 80 and the balls 79 are
sandwiched between the lower retainer sheet 78 and the upper
retainer sheet 81 such that the upper retainer sheet 81 can pivot
relative to the lower retainer sheet 78. The retainer ring 82
includes a ring body 83 with first and second retaining portions
extending from the ring body 83. The first retaining portion
includes a plurality of projections 84 radially and outwardly
extending from the ring body 83. The second retaining portion
includes a plurality of hooks 85 extending downwardly from the ring
body 83. After assembled, the ring body 83 is received within the
upper retainer sheet 81, with the first retaining portion (i.e. the
projections 84) seated upon an upper surface of the upper retainer
sheet 81 and the second retaining portion (i.e. the hooks 85)
disposed under the lower retainer sheet 78, thereby retaining the
upper retainer sheet 81 and the lower retainer sheet 78 together.
The lower edge 76 is mounted to the base unit 12 in a suitable
manner, e.g. with flat tapping screws 86 in this illustrated
embodiment. However, the lower edge 76 may be mounted to the base
unit 12 with snap-fit fasteners in an alternative embodiment
described below.
[0033] The handle assembly 20 is mounted to the base unit 12. In
particular, the handle assembly 20 includes a generally horizontal
section extending from the base unit 12 and a generally upright
section extending from the horizontal section. Mounted to an
underside of a junction of the horizontal section and the upright
section is a wheel assembly 87. This wheel assembly 87 facilitates
movement of the twister 10. However, in an embodiment not
illustrated, a support pad may be mounted to the handle assembly 20
in lieu of the wheel assembly 87. A handle bar 88 is attached to a
top of the upright section, for being grasped by a user during an
exercise. The specific structure of the handle assembly 20
described herein is for the purposes of illustration only and
therefore should not be regarded as limiting. The handle assembly
or the handle bar is optional and therefore a twister may not
include the handle bar 88 or the entire handle assembly 20 in
another embodiment not illustrated.
[0034] A pair of resistance bands 90 is attached to the base unit
12. During an exercise, the resistance bands 90 can, among others,
increase resistance to the arms to exercise the arms, chest or back
muscle of a user. The resistance bands 90 can also be used to help
the user keep balance during exercise. As described above, the
resilient member 16 resiliently supports the foot support 14
thereon. Therefore, the foot support 14 can be moved up-and-down in
a direction parallel to the pivot axis of the shaft 30 by a user
performing jumping, skipping or similar exercises.
[0035] In the embodiment described above, the foot support 14 can
be pivoted relative to the base unit 12 by a user performing a
twist exercise. During the pivotal movement, the biasing assembly
16 biases the foot support 14 toward the neutral position of the
foot support 14 and defines the left and right extreme positions of
the foot support 14. The foot support 14 can also be moved
up-and-down by a user performing jumping or similar exercises. The
foot support 14 can also be pivoted and moved up-and-down at the
same time when the user twists his or her hips or legs and at the
same time jumps on the foot support 14. Therefore, the twister 10
can provide a single pivotal movement, a single vertical movement,
and a combination of pivotal and vertical movements depending upon
the exercise the user performs.
[0036] FIGS. 7 and 8 illustrate another embodiment of the twister
designated by reference numeral 210. In the drawings, like numerals
are used to refer to like elements as in the previous embodiment
and those elements that are the same as in the previous embodiment
are not described herein. The twister 210 of this embodiment is
similar to the twister 10 described above except for the addition
of a secondary resilient member 216 and the use of snap-fit
fasteners 286.
[0037] As shown, the twister 210 includes a resilient assembly
including the resilient member 16 and the secondary resilient
member 216 disposed along the pivot axis. The secondary resilient
member 216 is shorter than the resilient member 16. In a specific
example illustrated in FIGS. 9 to 11, the resilient member 16 is a
90 KG spring which has an uncompressed length (i.e. the height) of
182 mm and a fully compressed length of 85 mm. When the spring is
compressed 80%, the spring length is 104.4 mm. The secondary
resilient member 216 is a spring with an uncompressed length of 120
mm. When the spring 16 is compressed to 120 mm, the secondary
spring 216 starts to be compressed (FIG. 10). When the spring 16 is
compressed to 104.4 mm, the secondary spring 216 is compressed 15.6
mm (FIG. 11) which provides an additional support of 300N. It is to
be noted that this specific example is for the purposes of
illustration only and should not be regarded as limiting.
[0038] The snap-fit fasteners 286 are used to mount the outer cover
70. The use of the snap-fit fasteners 286 facilitates the removal
of the outer cover 70. With the outer cover 70 removed, the user
can perform maintenance of various internal components of the
twister. The user can also replace each spring of the resilient
assembly with a suitable one depending upon the weight of the
user.
[0039] As various changes could be made in the above without
departing from the scope of the invention, it is intended that all
matter contained in the above description and shown in the
accompanying drawings shall be interpreted as illustrative and not
in a limiting sense.
