Abstract
An abdominal exercise equipment is provided with two front wheels and two rear wheels to ensure that the abdominal exercise equipment can move stably without tipping over during movement, preventing the exerciser from losing balance and getting hurt. A return gear assembly is disposed between the two rear wheels to produce a recovering force. Therefore, when the abdominal exercise equipment is pulled back, the recovering force will assist the exerciser to pull the abdominal exercise equipment back, which consequently lowers the difficult level of exercise. Furthermore, the abdominal exercise equipment is provided with a vibration device which is capable of softening the muscles and fat, and speeding up fat loss by producing vibration.
Claims10
An abdominal exercise equipment comprising:
- a housing including a longitudinal direction and being formed with a receiving chamber, a base of the housing being formed at both sides thereof in the longitudinal direction with two opposite rear-wheel holes, two opposite front-wheel holes, and an assembling hole between the two front-wheel holes, the housing being formed at both sides thereof in the longitudinal direction with two inserting holes;
- a rear wheel assembly including two rear wheels and a gear shaft and disposed in the receiving chamber in such a manner that the two rear wheels are inserted through the two rear-wheel holes and exposed out of the housing;
- a front wheel assembly including two front wheels and a connecting shaft, the connecting shaft including a transverse shaft connected between the two front wheels, in the middle of the transverse shaft being formed a longitudinal shaft to be inserted through the assembling hole of the housing;
- a vibration device disposed in the receiving chamber of the housing and including an eccentric wheel and a power source, the power source being electrically connected to an electric power supply unit and serving to rotate the eccentric wheel, so as to produce vibration;
- a return gear assembly disposed in the receiving chamber and comprising a gear and two return members, the gear including a central shaft inserted in the two return members, each of the return members including an elastic portion in a middle thereof, a transverse leg at one end of the elastic portion to engage with the gear, and a longitudinal leg at another end of the elastic portion to engage with the housing, the return gear assembly further including a two-step gear with a first step portion to be engaged with the gear shaft and a second step portion to be engaged with the gear, and the first step portion has a diameter greater than the second step portion;
- and
- two handles each including an assembling member which has one end inserted in the inserting holes of the housing and another end pivotally connected to a gripping rod, and the gripping rod of one of the handles being provided with a vibration-control switch to control the power source.
