Description
- The present invention relates generally to exercise devices, and, more particularly, to a twister device capable of providing a combination of pivotal and vertical movements.
- Various types of exercise devices exist to develop different parts of the body. One form of know exercise devices is a twister type device which utilizes a pivoted disk in the form a turntable. The users would step on the disk or turntable and twist at the hips to cause a pivotal movement of the disk or turntable.
- This type of twister devices can only provide a single form of movement, i.e. the pivotal movement. It would be desirable if some combination exercise device could be provided which incorporates the benefits of multiple forms of movements, e.g. pivotal as well as vertical movements.
- In one aspect, a twister generally includes a base unit, a foot support, a resilient assembly, and a biasing assembly. The foot support may be disposed over the base unit for a pivotal movement about a pivot axis relative to the base unit between a neutral position and left and right extreme positions of the foot support. The resilient assembly may be arranged to resiliently support the foot support to allow for a vertical movement of the foot support. The biasing assembly may be arranged to bias the foot support toward the neutral position during the pivotal movement of the foot support.
- In another aspect, a twister generally includes a base unit, a shaft, and a foot support. The shaft extends substantially perpendicularly from the base unit and defines a pivot axis. The foot support may be movably mounted to the shaft above the base unit. The foot support may provide one of a single vertical movement, a single pivotal movement, and a combination of vertical and pivotal movement depending upon a user's exercise on the foot support.
- In still another aspect, a twister includes a base unit. A shaft extends substantially perpendicularly from the base unit. A foot support may be pivotably mounted to the shaft for pivoting relative to the base unit. A resilient assembly may be disposed between the base unit and the foot support to resiliently support the foot support. The resilient assembly engages the foot support and the base unit in a manner so as to permit the pivotal movement of the foot support.

In the illustrated embodiment, thetwister 10 generally includes abase unit 12, afoot support 14, aresilient member 16, abiasing assembly 18, and ahandle assembly 20. - The
base unit 12 is configured to be anchored to or supported by a floor. In the illustrated embodiment, thebase unit 12 includes abase frame 22 and abase cover 24 mounted to cover thebase frame 22. As illustrated, thebase 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 thebase frame 22 could be of any suitable shape. - Also referring to
FIG. 2 , thebase frame 22 is generally cross-shaped formed by twosupport beams 26. Eachsupport beam 26 has twomounting slots 28 defined on opposite sides of the intersection, respectively. Eachmounting slot 28 has a narrow portion and a wide portion in communication with each other. Themounting slots 28 are used to mount thebiasing assembly 18 as described below. - A
shaft 30 extends perpendicularly upward from an intersection of the twosupport beams 26. Theshaft 30 defines a pivot axis along its longitudinal axis. - The
foot support 14 is configured to support a user thereon for performing various exercise activities. In the illustrated embodiment, thefoot support 14 includes afoot support frame 32 and afoot support panel 34. As illustrated, thefoot support frame 32 includes two parallelfirst support beams 36 and onesecond support beam 38 traversely connecting the twofirst support beams 36. Apivot hole 40 is defined through a general middle area of the traversesecond support beam 38. With theshaft 30 received into thepivot hole 40, thefoot support frame 32 is capable of pivoting about the pivot axis. Thefoot support panel 34 is fixedly mounted to and thus supported by thefoot support frame 32. As thefoot support frame 32 is pivotable about the pivot axis, thefoot support panel 34 and theentire foot support 14 are thus pivotable about the pivot axis. - The
foot support panel 34 can be mounted to thefoot support frame 32 in any suitable manner. In the illustrated embodiment, thefoot support panel 34 is fastened to thefoot support frame 32 withfasteners 42. To this end, the support beams 36, 38 of thefoot support frame 32 also definefastening holes 44 therethrough. Although not illustrated, thefoot 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. - The
foot support panel 34 includes one or more, such as, a pair of side-by-sidefoot pedal areas 46 formed or provided thereon. Each of thefoot pedal areas 46 has a plurality ofprotrusions 48 extending upwardly therefrom, for engaging with and for massaging the feet of the user. Thefoot pedal areas 46 and theprotrusions 48 are preferably made of rubber or other soft materials, for comfortably engaging with the user. - While the
foot support 14 is illustrated as including the discretefoot support frame 32 andfoot support panel 34 together, it is noted that thefoot support 14 may also be formed as a unitary structure with a foot support frame and a foot support panel integrated together. Therefore, thefoot support frame 32 and thefoot support panel 34 can be either discrete elements or integrally formed together into a unitary structure. - 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 asensor unit 50 mounted on thefoot support frame 32 and adisplay unit 52 provided on thefoot support panel 34. Thesensor unit 50 operates to sense information associated with the user's exercise activities. Thedisplay unit 52 is electrically connected to thesensor unit 50 to display the information sensed by thesensor 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 thefoot support 14 in the illustrated embodiment, it is to be understood that the exercise information generating assembly can be disposed on other parts of thetwister 10 in alternative embodiments. For example, at least thedisplay unit 52 could be disposed on a top portion of thehandle assembly 20. - Also referring to
FIGS. 3 to 5 , in the illustrated embodiment, theresilient member 16 includes a spring attached around theshaft 30. Thespring 16 is disposed between thebase unit 12, in particular, thebase frame 22, and thefoot support 14, in particular, thefoot support frame 32. The resilient member orspring 16 has opposite spring ends 54 and 56 slidable relative to thebase frame 22 andfoot support frame 32, respectively. Therefore, the resilient member orspring 16 resiliently supports thefoot support 14 thereon while permitting the pivotal movement of thefoot support 14. A pair ofend plates 58 is disposed between thespring end 54 and thebase frame 12, and between thespring end 56 and thefoot support frame 32, respectively. Theend plates 58 limit the position of theresilient member 16. As illustrated, theend plate 58 is circular-shaped. However, it is to be understood that theend plate 58 could be of another shape as long as it can provide the functions illustrated above. In the illustrated embodiment, theend plates 58 are fixed to thefoot support frame 32 and thebase frame 22, respectively, in any suitable manner, for example, by welding. While theresilient member 16 is implemented as a spring in the illustrated embodiment, it is to be understood that theresilient member 16 could be any suitable resilient structure as long as it can bias thefoot support 14 upward or resiliently support thefoot support 14. A bearingunit 59 is disposed around theshaft 30 between thespring end 54 and thebottom end plate 58. The bearingunit 59 includes rollers or balls therein to reduce friction during pivot movement of thefoot support 14 of thetwister 10. - The biasing
assembly 18 is connected between thebase unit 12 and thefoot support 14 to control the pivotal movement of thefoot support 14. In the illustrated embodiment, the biasingassembly 18 includes a resistance assembly having a plurality ofresistance cords 60 made of, for example, latex. In the specific exemplary embodiment as shown, the number of theresistance cables 60 is four. The plurality ofresistance cords 60 are evenly distributed around theshaft 30. Theresistance cords 60 are connected to thebase unit 12, in particular, thebase frame 22, and thefoot support 14, in particular, thefoot support frame 32 in any suitable manner. In the specific embodiment as shown, eachresistance cord 60 has opposite expanded cord ends 62 and 64. As can be best seen fromFIG. 3 , theresistance cords 60 are inserted into the narrow portions of the respective mountingslots 28, with the expanded ends 62 engaging thebase frame 22 around the narrow portions of the mountingslots 28, and plugs 66 are engaged within the wide portions of the mountingslots 28. In this way, thecable cords 62 are secured to thebase unit 12, in particular, thebase frame 22. By achieving this, eachcable 60 is first inserted through the wide portion of a corresponding mountingslot 28 and then slided to the narrow portion, and finally theplug 66 is inserted into the wide portion of the mountingslot 28. The other cord ends 64 may be secured in the same or a different manner. - 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 thefoot support 14 about the pivot axis. During this pivotal movement of thefoot support 14, the biasing assembly orresistance assembly 18 applies a resistance force against the pivot movement of thefoot support 14 away from a neutral position of thefoot support 14. In other words, the biasingassembly 18 is arranged to bias thefoot support 14 toward the neutral position of thefoot support 14. As used in this disclosure and the appended claims, the term “neutral position” is intended to mean the position as shown inFIGS. 3 to 5 where no user applies a twist or pivot force on thefoot support 14 or no user stands on thefoot support 14 doing an exercise. The side-to-side pivotal movement of thefoot 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, thefoot support 14 is pivoted away from or toward the neutral position during the pivotal movement of thefoot support 14. In this neutral position, as shown in the drawings, theresistance cords 60 are positioned in parallel with each other and with theshaft 40. - 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 orresistance assembly 18, through theresistance cords 60 which are stretched, applies a resistance force against such pivotal movement. Therefore, the user needs to overcome this resistance force of the biasingmember 18 during the exercise. The pivotal movement of thefoot 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 thefoot support 14 is pivoted away from the neutral position, the more difficult the user would feel to overcome such resistance force. Therefore, theresistance assembly 18 can also be used to define these left and right extreme positions where the resistance force of theresistance assembly 18 increases to a value that the user is not able to overcome. - Referring again to
FIG. 1 , thetwister 10 further includes a resilientouter cover 70. Theouter cover 70 is disposed to cover at least a part of thetwister 10. In the illustrated embodiment, theouter cover 70 is disposed between thebase unit 12 and thefoot support 14 to cover elements between thebase unit 12 and thefoot support 14. The resilientouter cover 70 is deformable in a direction parallel to the pivot axis in compliance with the vertical movement of thefoot support 14 along the pivot axis. The resilientouter cover 70 is also mounted to one of thebase unit 12 and thefoot support 14 but pivotable relative to the other of thebase unit 12 and thefoot support 14 about the pivot axis in compliance with the pivot movement of thefoot support 14 about the pivot axis. - In the illustrated embodiment, the
outer cover 70 has acover body 72 with anupper edge 74 and alower edge 76. Thecover 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 thefoot support 14. Theupper edge 74 is movably connected to thefoot support frame 32 to permit the pivotal movement of thefoot support 14 relative to theouter cover 70. In the illustrated embodiment, theupper edge 74 is mounted to thefoot support frame 32 through a bearingstructure 77. The bearingstructure 77 includes alower retainer sheet 78, a plurality ofballs 79, aball fixing ring 80, anupper retainer sheet 81, and aretainer ring 82. Also referring toFIG. 6 , thelower retainer sheet 78 is fixed to theupper edge 74 of theouter cover 70 in any suitable manner, for example, with self-plugging rivets. Theupper retainer sheet 81 is fixed to thefoot support frame 32 in any suitable manner. Theball fixing ring 80 has holes receiving theballs 79 therethrough. The combination of theball fixing ring 80 and theballs 79 are sandwiched between thelower retainer sheet 78 and theupper retainer sheet 81 such that theupper retainer sheet 81 can pivot relative to thelower retainer sheet 78. Theretainer ring 82 includes aring body 83 with first and second retaining portions extending from thering body 83. The first retaining portion includes a plurality ofprojections 84 radially and outwardly extending from thering body 83. The second retaining portion includes a plurality ofhooks 85 extending downwardly from thering body 83. After assembled, thering body 83 is received within theupper retainer sheet 81, with the first retaining portion (i.e. the projections 84) seated upon an upper surface of theupper retainer sheet 81 and the second retaining portion (i.e. the hooks 85) disposed under thelower retainer sheet 78, thereby retaining theupper retainer sheet 81 and thelower retainer sheet 78 together. Thelower edge 76 is mounted to thebase unit 12 in a suitable manner, e.g. with flat tapping screws 86 in this illustrated embodiment. However, thelower edge 76 may be mounted to thebase unit 12 with snap-fit fasteners in an alternative embodiment described below. - The
handle assembly 20 is mounted to thebase unit 12. In particular, thehandle assembly 20 includes a generally horizontal section extending from thebase 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 awheel assembly 87. Thiswheel assembly 87 facilitates movement of thetwister 10. However, in an embodiment not illustrated, a support pad may be mounted to thehandle assembly 20 in lieu of thewheel assembly 87. Ahandle bar 88 is attached to a top of the upright section, for being grasped by a user during an exercise. The specific structure of thehandle 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 thehandle bar 88 or theentire handle assembly 20 in another embodiment not illustrated. - A pair of
resistance bands 90 is attached to thebase unit 12. During an exercise, theresistance bands 90 can, among others, increase resistance to the arms to exercise the arms, chest or back muscle of a user. Theresistance bands 90 can also be used to help the user keep balance during exercise. As described above, theresilient member 16 resiliently supports thefoot support 14 thereon. Therefore, thefoot support 14 can be moved up-and-down in a direction parallel to the pivot axis of theshaft 30 by a user performing jumping, skipping or similar exercises. - In the embodiment described above, the
foot support 14 can be pivoted relative to thebase unit 12 by a user performing a twist exercise. During the pivotal movement, the biasingassembly 16 biases thefoot support 14 toward the neutral position of thefoot support 14 and defines the left and right extreme positions of thefoot support 14. Thefoot support 14 can also be moved up-and-down by a user performing jumping or similar exercises. Thefoot 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 thefoot support 14. Therefore, thetwister 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. -
FIGS. 7 and 8 illustrate another embodiment of the twister designated byreference 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. Thetwister 210 of this embodiment is similar to thetwister 10 described above except for the addition of a secondaryresilient member 216 and the use of snap-fit fasteners 286. - As shown, the
twister 210 includes a resilient assembly including theresilient member 16 and the secondaryresilient member 216 disposed along the pivot axis. The secondaryresilient member 216 is shorter than theresilient member 16. In a specific example illustrated inFIGS. 9 to 11 , theresilient 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 secondaryresilient member 216 is a spring with an uncompressed length of 120 mm. When thespring 16 is compressed to 120 mm, thesecondary spring 216 starts to be compressed (FIG. 10 ). When thespring 16 is compressed to 104.4 mm, thesecondary 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. - The snap-
fit fasteners 286 are used to mount theouter cover 70. The use of the snap-fit fasteners 286 facilitates the removal of theouter cover 70. With theouter 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. - 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.
