Abstract

An improved wobbling mechanism of a riding fitness machine comprises a pedestal, a power source, a driving structure which undulates and swings back and forth, a rocker component, a left and right sloping structure, and a saddle. The improved wobbling mechanism is mainly characterized in that a base and a middle seat, which are pivotally connected, are arranged on the pedestal; the left and right sloping structure includes a rotating shaft; the rotating shaft is connected with a driving main shaft of the driving structure which undulates and swings back and forth through a transmission belt; an eccentric crank shaft is arranged at one end of the rotating shaft; the eccentric crank shaft is combined and linked with the base by a first traction part, a second traction part, a supporting part and a support in sequence; the first traction part, the second traction part, the supporting part, and the support are a combination which is pivotally connected and can at least move to one direction; and the inclination angle of the pivotally connected combination can be appropriately changed by the first traction part, the second traction part, the supporting part, and the support. When the driving structure, which undulates and swings back and forth, drives the left and right sloping structure, the saddle swings and slopes from left to right and vice versa, thereby avoiding the dead point of the movement. The left and right sloping structure has the advantages of smooth operation, no noise, low failure rate and the like.

Description

The improvement of horseback riding body-building machine wabbler mechanism

Technical field

The utility model relates to a kind of horseback riding body-building machine wabbler mechanism improvement, be meant that especially can make the appropriate tilt angle between the composed component of its structure that tilts changes, when front and back fluctuating wobble drive structure drives the structure that tilts and makes seat cushion tilt swing, can avoid producing the wabbler mechanism at the dead point of start and improve.

Background technology

The technology of at present relevant horseback riding body-building machine sees also a day disclosure special permission communique spy and opens 2004-344684 number, the spy opens 2005-296677 number, and Taiwan patent I270393 number, I268794 number, I270394 number, I268793 number, I256901 number, I232116 number, M284401 number, on its structure nothing more than seat cushion with a simulation saddle seat, and drive plural gear and plural lever via a motor, and by plural gear and plural lever drives seat cushion, make seat cushion present front and back fluctuating swing, and before and after it fluctuating wobble drive structure in running also the driving by gear drive the structure that tilts, seat cushion is presented tilt swing, but the media by gear drives the structure that tilts, it is derived the manufacturing cost height, noise is big, the problem of easy fault, so the inventor has applied for the Taiwan patent M304360 number, M323307 number, it is dull that it has improved known horseback riding body-building machine running, move mechanical, the disappearance that variability is not high, and the driving that improves known horseback riding body-building machine mat gear drives the problem that structure produced that tilts.

And the draw bar of the structure that tilts in this Taiwan patent M323307 number is to be arranged in between the base and seat of pivot joint shape, when draw bar is driven by a crank axle, mat the 3rd crank axle position forms the variation that moves up and down, and can force traction drive in seat and seat cushion be fulcrum with base with middle articulated section, back and forth swing tilts, this draw bar is two fulcrum (links up and down, pivot end) though is respectively equipped with bearing and is made as joint structure and constitutes moving fulcrum, can be convenient to the tilt angle of shape of draw bar changes, the action that makes seat cushion tilt to swing back and forth is smooth and easy, but the draw bar body of rod is a complete body, can't do the variation of bending angle, it tilts still can produce start dead point (Dead Point) when swinging back and forth action, and the bursting stress major part during work can concentrate on draw bar two fulcrums, so the proportion of goods damageds of draw bar are improved, so the structure that tilts of Taiwan patent M323307 number still remains to be improved part and necessity.

Therefore, the inventor is in line with being engaged in the practical experience that this industry is developed for many years, and actively research and development thinking with great concentration through contrived experiment many times, has caused generation of the present utility model.
