## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a waistline slimming exercise machine, and more particularly to a waistline slimming exercise machine in which the swing mechanism moves vertically, and the two swing arms have an offset between each other and drive a linkage member so that the driving element causes the pedal to simultaneously swing left and right so that the user performs not just a stepping exercise but also a waist twisting exercise from the two different movements provided by the pedals.
2. Description of the Related Art
Currently, most indoor exercise machines simulate outdoor exercise movements, permitting users to achieve the same exercise effects in a limited indoor space. For example, stepping machines allows the user to step on pedals alternatively to simulate a walking exercise.
A typical stepping machine, as shown in FIG. 16, has two pedals 40 pivoted onto a base 41, and a linkage mechanism connects together the two pedals 40 and a hydraulic cylinder 42. The damping effect provided by the hydraulic cylinder 42 causes the pedal 40 to be lifted alternatively and maintains synchronization between the two pedals 40, while the damping force provided by the hydraulic cylinder 42 to the pedals 40 makes work for the user to provide exercise.
However, the prior art stepping machine can only provide exercise movements for legs, and the other parts of the body do not benefit from the machine. Another small exercise machine provides a horizontal rotating plate on the base which allows users to twist their body below the waistline left and right repeatedly. Then again, this type of exercise machine can only provide exercise movements for the waistline, while the other parts of body similarly do not benefit from the machine.
Therefore, it is desirable to provide a waistline slimming exercise machine to mitigate and/or obviate the aforementioned problems.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
First, please refer to FIGS. 1, 2 and 3. A waistline slimming exercise machine comprises: a base 10, a swing mechanism 20 and a peddle element 30. The base 10 is an H-shaped frame, and a lower center connecting member 11 with a U shape is disposed at the center of its central beam, and an internal assembly space 111 is formed inside connecting member 11 and a through aperture 112 and a locking aperture 113 are located on the two side walls of connecting member 11. A stop 12 is disposed and screwed onto two sides of the base 10 that are shorter in length than the central beam, and the stop 12 is adjustable in height by way of screws. The base 10 has an extended handle 13 at a predetermined position, as shown in FIG. 4. A swing mechanism 20 comprises a upper center connecting member 21 and inclining swing arms 22, 22′ disposed on two sides of the upper center connecting member 21. The swing arms 22, 22′ couple to respective shock absorbers 23, and to a first linkage member 24 and a second linkage member 25. The upper center connecting member 21 has a slot at its bottom, a combining apertures 211 on two side respective walls and a first aperture 212 on its top surface. An assembly end 221 is disposed respectively on the bottom of the upper end of the swing arms 22, 22′ and combines with the shock absorbers 23, and the other end of each shock absorber 23 includes a securing end 231. Each swing arm 22, 22′ has a second pivoting end 222 at its upper end. The swing arm 22′ has a connecting end 223 for securing the combining aperture 211 of the upper center connecting member 21 and a tapped aperture 224 on its top surface. The tapped aperture 224 is secured to the first aperture 212 of the upper center connecting member 21 by way of a screw 225. Therefore, the upper center connecting member 21 of the swing mechanism 20 and the swing arm 22′ can be separated to provide for a smaller storage space. However, the swing arms 22, 22′ can also be directly attached to the upper center connecting member 21 (as shown in FIG. 5). The first linkage member 24 has a first pivoting end 241 on its upper end and a first assembly end 242 on another end. The swing mechanism 20 further has a second linkage member 25; one end of the second linkage member 25 is attached by way of a driving element 26, and the driving element 26 includes a push-pull bar 261, a first connecting end 262 and a second connecting end 263. The first connecting end 262 and the second connecting end 263 provide a universal joint or a universal bearing. The peddle element 30 is capable of being combined with the swing mechanism 20, and it comprises a balance base 31 and a peddle 32. The balance base 31 has a pivoting space 311 on its bottom, a first aperture 312 and a connecting aperture 313 on two side walls for securing purposes, and a protrusion hole 314 at a center position of its upper face. The peddle 32 has a rotating plate 321 on its bottom face and a pivot axle 322 aligned with the protrusion hole 314 at its center position, and the peddle 32 or the rotating plate 321 has an assembly aperture 323 at a predetermined position. Alternatively, as shown in FIG. 6, another combination of the balance base 31 and the peddle 32 includes an opened indentation hole 314 that is located at the center position of the balance base 31 and paired with a bearing 315, and the rotating plate 321 of the peddle 32 is combined with the bearing 315 of the balance base 31 with the pivot axle 322.
For further views of the assembly structure please refer to FIGS. 2, 3 and 7. The swing mechanism 20 utilizes the upper center connecting member 21 to connect together the two swing arms 22, 22′ and to attach to the through aperture 112 of the internal assembly space 111 of the base 10 by way of the combining aperture 211. The shock absorbers 23 and the first linkage members 24 of the swing arms 22, 22′ respectively utilize the securing end 231 and the first assembly end 242 for screwing onto the locking aperture 113 of the internal assembly space 111 of the base 10, and the second pivoting ends 222 of the swing arms 22, 22′ are respectively secured to the first apertures 312 of the pivoting spaces 311 of the balance bases 31. The first pivoting end 241 of the first linkage member 24 is secured to the pivoting space 311 of the balance base 31 and screwed to the connecting aperture 313 of the pivoting space 311. Furthermore, the second linkage member 25 can be attached onto the first linkage member 24 of the swing mechanism 20 or any suitable position on the swing mechanism 20 such as on the swing arm 22 or the shock absorber 23. The driving element 26 at one end of the second linkage member 25 utilizes the first connecting end 262 for securing to the assembly aperture 323 on the peddle 32 or the rotating plate 321. Therefore, when the second linkage member 25 moves vertically with the swing arm 22, the driving element 26 causes the peddle 32 to rotate with a biased movement.
For operation of the device please refer to FIG. 8 and FIG. 9. The swing mechanism 20 utilizes the upper center connecting member 21 for attachment to the through aperture 112 of the lower center connecting member 11 of the base 10, and the securing end 231 of the shock absorber 23 and the first assembly end 242 of the first linkage member 24 are screwed onto the locking aperture 113 so that the swing mechanism 20 and the lower center connecting member 11 form an inclined angle. The second pivoting end 222 of the swing arm 22 and the first pivoting end 241 of the first linkage member 24 are respectively attached to the first aperture 312 and the connecting aperture 313 of the balance base 31 so that the swing arm 22, the first linkage member 24, the lower center connecting member 11 and the balance base 31 form a four-way linkage mechanism that allows the peddle 32 to generate vertical movement. The first linkage member 24 of the swing mechanism 20 has the second linkage member 25, and the driving element 26 at another end of the second linkage member 25 utilizes the first connecting end 262 for securing to the peddle 32 or the assembly aperture 323 of the rotating plate 321. Therefore, when a user uses the exercise machine and causes the swing mechanism 20 to move vertically, the swing arm 22 and the first linkage member 24 have an offset between each other due to the four-way linkage mechanism. When the peddle 32 is pressed down, as shown in FIG. 10, the second linkage member 25 secured onto the first linkage member 24 is driven to move down, and the driving element 26 at the other end of the second linkage member 25 generates a pulling force. With the mechanical relationship established between the push-pull bar 261 and the first connecting end 262, the pulling force is transformed into a horizontal rotating force at the first connecting end 262 and so the assembly aperture 323 of the peddle 32 is pulled away from the pivot axle 322. Moreover, when the other peddle 32′ is driven to move upward, the first linkage member 24 moves upward and drives the second linkage member 25 to rotate counter-clockwise so that the driving element 26 at the other end of the second linkage member 25 generates an inward pushing force. With the push-pull bar 261 and the first connecting end 262, the inward pushing force is transformed into a horizontal rotating force at the first connecting end 262 which causes the assembly aperture 323 of the peddle 32′ to rotate inward from the pivot axle 322 so that the pedal 32, 32′ simultaneously rotate counter-clockwise, as shown in FIG. 11. When the user steps on the peddle 32′, as shown in FIG. 12, the first linkage member 24 on the swing arm 22′ is pulled down, and so the second linkage member 25 of the first linkage member 24 moves downward, which causes the driving element 26 at the other end of the first linkage member 24 to generate an outward pulling force. With the mechanical relationship between the push-pull bar 261 and the first connecting end 262, the pulling force is transformed into a horizontal rotating force at the first connecting end 262, and so the assembly aperture 323 of the peddle 32′ rotates away from the pivot axle 322. The other peddle 32 is driven to move upward; the first linkage member 24 and the second linkage member 25 are driven to move upward, which causes the second linkage member 25 to generate an inward pushing force. With the mechanical relationship between the push-pull bar 261 and the first connecting end 262, the inward pushing force is transformed into a horizontal rotating force at the first connecting end 262, which causes the assembly aperture 323 of the peddle 32 to rotate inward from the pivot axle 322 so that the pedal 32, 32′ simultaneously rotate clockwise, as shown in FIG. 13. With the above-mentioned structure, when the user does stepping exercises on the machine, he or she is doing not just stepping exercises but also waist twisting exercises.
Please refer to FIG. 14 and FIG. 15. In another embodiment of the present invention, the swing mechanism 20 comprises a upper center connecting member 21 and inclining swing arms 22, 22′ are disposed on two sides of the upper center connecting member 21. The swing arms 22, 22′ are combined with shock absorbers 23 and first linkage members 24. The upper center connecting member 21 has a slot at its bottom, a combining apertures 211 on its two side walls and a first aperture 212 on its top surface. An assembly end 221 is disposed at the bottom of the upper end of the swing arms 22, 22′ and couples with the shock absorbers 23, while each other end of the shock absorbers 23 has a securing end 231. The swing arms 22, 22′ have a second pivoting end 222 at their upper ends. The swing arm 22′ has a connecting end 223 for securing to the combining aperture 211 of the upper center connecting member 21 and a tapped aperture 224 on its top surface. The tapped aperture 224 is secured to the first aperture 212 of the upper center connecting member 21 with a screw 225. The first linkage member 24 has a first pivoting end 241 on its upper end and a first assembly end 242 on another end. The swing mechanism 20 further has an extended driving arm 243; one end of the driving arm 243 is attached with a driving element 26, and the driving element 26 has a push-pull bar 261, a first connecting end 262 and a second connecting end 263. After the swing mechanism 20 and the base 31 of the peddle element 30 are assembled, the extended driving arm 243 of the first linkage member 24 also has the driving element 26, and the other end of the driving element 26 utilizes the first connecting end for attachment to the peddle 32 or the rotating plate 321. With the movement of the first linkage member 24, the driving element 26 of the driving arm 243 causes the peddle 32 to rotate with a biased movement
With the above-mentioned structures in the embodiments, the present invention has the following benefits: in the waistline slimming exercise machine, the swing mechanism 20 has two second linkage members 25; when a user uses the exercise machine to cause the swing mechanism 20 to move vertically, the second linkage member 25 moves vertically with the swing arm 22, and the driving element 26 causes the peddle 32 to rotate with a biased movement. Therefore, when the user does stepping exercises on the machine, he or she is doing not just stepping exercises but also waist twisting exercises with the two different movements provide by the pedals 32.
Although the present invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
