The present invention relates to a swingable exercise bicycle, especially to one that able to swing left and right and shaft back and forth, which achieves intense exercise.
Exercise bicycle enhance body muscle by pedaling in situ which drive turning gear to spin. When the weather is bad or people are lack of time to do outdoor exercise, exercise bicycle provides a choice for indoor exercise.
Unfortunately, users easily feel bored about pedaling. Also, unchanged posture brings negative effect to human body
Also, the swingable exercise bicycle can swing left and right and up and down. User's slightly body movement which changes the center of weight can easily motivate the buffer 930 and reciprocating device 940 function of shaking saddle support frame 920, but it cannot achieve the purpose of workout and sweating profusely.
It is a primary objective of the present invention to provide a swingable exercise bicycle mechanism which swing left and right repeatedly by shaking users' body.
It is another objective of the present invention to provide a swingable exercise bicycle mechanism which takes users' huge effort to change the center of weight to generate component force for reciprocating that make bicycle shifting.
In order to achieve the above objectives, a swingable exercise bicycle includes a base frame, pedestals at the front and rear with pivot inside, two extension spring arranged symmetrically in pairs connecting with fastening seat, and fastening seat does pivot turn at both sides said opposite torque from symmetrically extension spring to fastening spring; at least one sliding shaft said correspond to locating hole of fastening seat; a slider said a least one shaft hole on horizontal axle, arranged on sliding shaft, make slider slide back and forth on sliding shaft; a buffer arranged between slider and fastening seat, generating damping effect when slider move on the sliding shaft; a swingable exercise bicycle said a bicycle frame, a bicycle handle, a saddle, a pedal and a turning gear, and the bottom of bicycle frame is locked on the top of slider;
Whereby when the users start pedaling and applying force to the bicycle frame by swinging users' body, the slider drives the fastening seat spin repeatedly, and the extension springs produce an opposite torque to enhance the swinging effect of exercise bicycle; Moving the center of gravity by shaking body back and forth applies axially component force of reciprocating which makes slider shift back and forth, and by overcoming the damping of buffer to achieve intense exercise effect.
Also, the swingable exercise bicycle mechanism as claimed in claim 1, wherein the brake arranged at the leading edge of the slider, said a lever and stop mechanism, when rotating the lever makes stop mechanism locks sliding shaft up and stops slider from moving on sliding shaft.
Furthermore, the swingable exercise bicycle mechanism as claimed in claim 1, wherein a locking device which locking bar set through base frame and fix the fastening seat at inner side.
Moreover, the swingable exercise bicycle mechanism as claimed in claim 1, wherein a bearing inside the pivot hole of fastening seats is set on the pivot of base frame to enhance spinning fluency.
Yet, the swingable exercise bicycle mechanism as claimed in claim 1, wherein the linearity bearing at both sides of slider, and each linearity bearing set a least one bearing hole corresponds to the sliding shaft making slider moves smoothly on the sliding shaft.
Yet, the swingable exercise bicycle mechanism as claimed in claim 5, wherein a buffer with two pair of return spring, and each return spring is connecting with linearity bearing and fastening seat.
Yet, the swingable exercise bicycle mechanism as claimed in claim 5, wherein said an elastic band surrounds the fastening seat and rubber wheel.
The fastening seat is set at front and rear side, the slider set on sliding shaft, the sliding shaft set through fastening seat and the bicycle frame lock on the top surface of the slider. When users swing their body left and right and apply force to the bicycle frame, the slider motivates fastening seat spinning repeatedly, and the extension spring arranged at the opposite side generate a torque in opposite direction to achieve effect of enhancing the swinging of the bicycle.
Between the slider and fastening seat said extension spring, elastic band, or any other kinds of buffer. When user moves back and forth intensely and pedaling the bicycle, it applies component force to the sliding shaft which makes slider reciprocating. Whereby overcoming damping of reciprocating achieve the effect of intense exercise.
Referring to
At the front of straight bar 12 is a pair of rubber tire 13 on both sides, the frame is easy moving with the rubber tire 13, plus the rear side of the base frame 10 is liftable, thereof in the middle of straight bar 12 said a pedestal 14, each pedestal 14 said pivot 15 inside; and each pedestal 14 said two hanging rod 16 on straight bar 12.
Each of two fastening seat 20 said a pivot hole 21, at least one locating hole 22 and hanging part 23. In first applicable embodiment, the fastening seat 20 said two locating hole 22; on the pivot of the pedestal 14 said two bearing 24 arranged inside the pivot hole 21 of the fastening seat 20, and the bearing 24 enhance the fluency of spinning of the fastening seat 20; four extension spring 30 arranged symmetrically in pair, connecting with hanging part 23 of fastening seat 20 and hanging rod 16 of base frame 10. When fastening seat 20 spin, the extension spring 30 apply torque in opposite direction to fastening seat 20.
In first applicable embodiment said at least one sliding shaft 40, said two sliding shaft 40 correspond to locating hole 22, the sliding shaft 40 set through the locating hole 22 of the fastening seat 20; a slider 50 said a least one shaft hole 51 on horizontal axle, and the both side of slider 50 said a linearity bearing 52, thereof linearity bearing 52 said at least one bearing hole 53; on the sliding shaft 40 said two shaft hole 51 and two bearing hole 53, whereby the slider 50 can slide smoothly on the sliding shaft 40. A locking device of said locking bar 251 which has a screw at the front for locking on pedestal 14 and the fastening seat 20, making two fastening seat 20 and sliding shaft 40 fixed among both pedestal 14. A buffer 60 produce damping effect while slider 50 sild on sliding shaft 40. In first applicable embodiment, the buffer 60 include two turn spring 61, and each return spring 61 connect with linearity bearing 52 and fastening 20, the return spring 61 produce damping effect while slider 50 slide on sliding shaft 40; at the front edge of the slider 50 said a brake 54, the brake 54 said a stop mechanism 542 and operation lever 541, rotating operation lever 541 motivate stop mechanism 542 to stop sliding shaft 40, therefor slider 50 stop shifting on sliding shaft 40.
The present invention said a fastening seat 20 at the front and rear of the base frame 10, a slider 50 arranged on sliding shaft 40, and the bicycle frame 71 is locked on the top surface of the slider 50; When users apply force to the bicycle frame 71 by shaking their body, the fastening seat 20, the slider 50 and exercise bicycle 70 spin and the extension spring 30 arranged on the both side of the fastening seat 20 provide a torque M in opposite direction, which enhances effect of swinging of the exercise bicycle 70. Moreover, the present invention said return spring 61, elastic band 62 or any kinds of buffer arranged between the slider 50 and the fastening seat 20; Whereby the force of shaking body intensely and pedaling force slider 50 shift in direction of X axis on the sliding shaft 40, also, users need pedaling faster and amplify their body movement to resist damping from the buffer 60, so as to achieve effect of intense exercise.
Although particular embodiments of the invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims.
