Description

Vibration seesaw exercise equipment {VIBRATION SEESAW EXERCISER}

The present invention relates to a vibrating seesaw exercise mechanism, and in particular, to transfer the vibration generated in the vertical direction through the rotation of the eccentric shaft to the scaffold of the exercise mechanism, by providing a seesaw movement by lifting one side of the scaffold by the vibration, The present invention relates to an exercise device that allows a user to perform a smoothing and strengthening of muscle muscles by vibration in a state where a limb is placed.

In general, exercise equipment for strengthening the lower body strength is a treadmill or step machine, such as a user uses a method to exercise by directly applying the force to the exercise equipment for users who are somewhat less muscle strength or users who require rehabilitation treatment It was not a suitable exercise device. Therefore, in recent years, an exercise device has been provided that can enhance muscle strength without applying force to the user. Most of the exercise device vibrates the scaffold by rotating an eccentric cam shaft by driving a driving motor. Looking at the prior art for the exercise device using the eccentric camshaft, as follows.

The muscle strengthening exercise device disclosed in Korean Patent Registration No. 283875 has a base placed on a horizontal plane; A post installed in front of the base; A footrest installed on the base so as to be movable up and down and on which the user puts his foot; A driving device disposed in the base to periodically lift both sides of the scaffolding in a seesaw manner; And a control panel mounted on the post to control driving of the driving device, wherein the driving device comprises: a driving source mounted to the base; A pair of drive pulleys fixed to the shaft of the drive source; A pair of driven pulleys disposed on both sides of each of the driving pulleys and connected by a belt; A pair of eccentric shafts fitted to the driven pulleys and arranged to have a predetermined obtuse phase difference between them; A bracket installed on the base to rotatably support both ends of each eccentric shaft; And a lower end rotatably connected to both ends of each of the eccentric shafts protruding from the bracket, and an upper end rotatably connected to the underside of the foot plate, and connecting rods that operate the foot plate in a seesaw manner by rotation of the eccentric shafts. A muscle strength-enhancing exercise mechanism comprising: a support rod, which is parallel to an axis of the drive source and fixed to a base, is disposed adjacent to a lower portion of the foot plate, and both sides of the foot plate are driven to seesaw operation around the support rod. A pair of balance weights are eccentrically fitted on each eccentric shaft so as to be located on the opposite side with respect to each driven pulley, and the eccentric portions of the respective balance weights are disposed so as to face the same direction as the eccentric portions of the eccentric shafts. It is configured to counteract the force acting in a direction opposite to the direction of movement of.

As described above, the strength-enhancing exercise mechanism is a power generated from the drive source is transmitted to the driven pulleys located on both sides by the belt, both sides of the scaffold as the driven shaft rotates the driven pulley formed by the eccentric shaft, respectively Since the alternating movement of the seesaw is caused to occur, not only friction loss occurs between the belt and the pulley when the driving source is driven, but also a lot of power is required to rotate the pair of driven pulleys. This requires a load of, resulting in increased power consumption. In addition, according to the service life of the belt, the maintenance is constantly required, the configuration of the exercise equipment is very complicated, there is a problem that it is not easy to replace the belt or damaged parts after long-term operation, the noise when driving the belt There was a problem that is unsuitable for use in a place where quiet operation is required to occur.

The present invention was devised to solve the above problems, and the object of the present invention is to transfer power to one drive motor by a belt as in the conventional case, and to convert it into cam motion to move up and down on both sides of the footrest. By applying up and down movement to only one side to reduce the power supplied to the drive motor as a result, the power generated from the drive motor is directly transferred from the drive shaft to the driven shaft using a coupling to minimize the loss during power transmission In particular, the simplification of the configuration to generate the vibration movement by coupling the eccentric shaft of the driven shaft to the bearing for the vertical movement, by providing a vibration seesaw exercise mechanism capable of quiet operation by the unique characteristics of the bearing Vibration movement transmitted from the instrument to strengthen the muscles of the limbs.

In more detail, the fixed base 24 coupled to the case 3 to form a bottom surface includes the driving motor 7 generating power at an upper center portion thereof, and being located at both sides of the driving motor 7. The center shaft fixing frame 23 is erected on both sides of the fixed base 24 in a predetermined position on both sides of the fixed base 24 to fix the footrest 2 so as to enable the seesaw movement, and to fix the eccentric driven shaft 81 at a predetermined position.
