The present invention relates to fitness machine technology, and more particularly to a harmonic vibration fitness machine that can realize single platform double amplitude operation.
The reciprocating vibration type harmonic vibration fitness machine disclosed in Taiwan Patent Publication No. 1660762 uses an actuating mechanism to simultaneously drive related components, and causes the platform components to move up and down relative to each other to produce the effect of body harmonic vertical vibration. However, the aforementioned patent documents only provide a single-amplitude operation mode, which is too monotonous in use and has little change, so the variability of the harmonic vibration that can be provided is limited, so there is room for improvement.
The present invention has been accomplished under the circumstances in view. It is the main object of the present invention to provide a harmonic vibration fitness machine that can realize single platform double amplitude operation, so that the variability of harmonic vibration usage can be multiplied.
To achieve this and other objects of the present invention, a harmonic vibration fitness machine comprises a machine body, a movable plate, a first drive unit, two first linkages, a second drive unit and two second linkages. The machine body comprises a base and a platform. The base comprises an upward accommodating space. The movable plate is set in the accommodating space and movable up and down relative to the base by the second linkages. The platform is set above the movable plate and drivable by the first linkages to move up and down.
From the above we can see that the harmonic vibration fitness machine of the present invention uses the first drive unit and the second drive unit to drive the first linkages and the second linkages respectively. On the one hand, the first linkages move the platform, one the other hand, the second linkages move the movable plate. Then the movable plate will also move the first linkages during the operation process, so that the up and down movement of the platform can obtain an additive effect. In this way, when the user puts his feet or other body parts on the platform, he can feel the double-amplitude vibration, so that the whole body can achieve the purpose of massage and fitness.
Preferably, each first linkage comprises a first support rod, a second support rod, a first upper transverse rod, a first lower transverse rod, a first adapter, a second adapter, a first vertical rod, a second vertical rod and a first drive rod. The bottom end of the first support rod and the bottom end of the second support rod are affixed to the top surface of the movable plate. The first upper transverse rod is pivoted to the opposing top end of the first support rod. The first lower transverse rod is pivoted to the opposing top end of the second support rod. The top end of the first adapter is affixed to the bottom surface of the platform. The bottom end of the first adapter is pivoted to the first upper transverse rod. The top end of the second adapter is affixed to the bottom surface of the platform. The bottom end of the second adapter is pivoted to the top end of the second vertical rod. The bottom end of the second vertical rod is pivoted to the first lower transverse rod. The opposing top and bottom ends of the first vertical rod are respectively pivoted to the inner end of the first upper transverse rod and the inner end of the first lower transverse rod. The first drive rod is located between the first support rod and the first vertical rod. The top end of the first drive rod is pivoted to the first upper transverse rod. The bottom end of the first drive rod is connected to an eccentric shaft at a respective one end of the first transmission shaft. With the above technical features, when the bottom end of the first drive rod is driven by the first transmission shaft, the first upper transverse rod is driven to swing up and down on the top end of the first support rod like a seesaw. Then, the first upper transverse rod drives the first adapter and the first vertical rod to move up and down, thereby causing the first vertical rod to drive the first lower transverse rod to swing up and down on the top end of the second support rod like a seesaw. Then, the first lower transverse rod drives the second vertical rod to move the second adapter and the first adapter synchronously up and down, causing the platform to move up and down.
Preferably, the top end of the first adapter and the top end of the second adapter are both affixed to a rack. The rack is affixed to the bottom surface of the platform so that the first linkages drive the rack to move the platform up and down.
Preferably, each second linkage comprises at least one third support rod, a fourth support rod, a third vertical rod, a second upper transverse rod, a second lower transverse rod, a third adapter, a fourth adapter, a second drive rod and a fourth vertical rod. The top end of the third support rod is pivoted to the second lower transverse rod. The opposing bottom end of the third support rod is affixed to the base. The top end of the fourth support rod is pivoted to the second upper transverse rod. The opposing bottom end of the fourth support rod is affixed to the base. The top end of the third vertical rod is pivoted to the outer end of the second upper transverse rod. The opposing bottom end of the third vertical rod is pivoted to the top end of the third adapter. The opposing bottom end of the third adapter is affixed to the top surface of the movable plate. The top end of the fourth adapter is pivoted to the outer end of the second lower transverse rod. The opposing bottom end of the fourth adapter is affixed to the top surface of the movable plate. The top end of the second drive rod is pivoted to the second lower transverse rod. The opposing bottom end of the second drive rod is coupled to an eccentric shaft at a respective one end of the second transmission shaft. The opposing top and bottom ends of the fourth vertical rod are respectively pivoted to the inner end of the second upper transverse rod and the inner end of the second lower transverse rod. With the above technical features, the second drive rod will drive the second lower transverse rod to swing up and down on the top end of the third support rod as a seesaw when the bottom end of the second drive rod is driven by the second transmission shaft. When the second lower transverse rod to swings up and down, it moves the fourth adapter and the fourth vertical rod, on the one hand making the fourth adapter to reciprocate up and down relative to the base, on the other hand causing the fourth vertical rod to swing up and down on the top end of the fourth support rod as a seesaw. During swinging of the second upper transverse rod, the third vertical rod drives the third adapter, causing the third adapter and the fourth adapter to synchronously reciprocate the movable plate up and down relative to the base.
Preferably, the movable plate has a large opening and a small opening. The large opening accommodates the second transmission shaft, the second transmission shaft bearing blocks, the third support rods and the fourth support rods. The small opening accommodates the fourth support rods. With the above technical features, the movable plate will not interfere with the aforementioned components when moving up and down.
Preferably, the first motor can be selectively mounted on the base or the movable plate according to actual needs, and the second motor is mounted on the base.
