Oval orbit exercise bike
Abstract
An oval orbit exercise bike comprises a flywheel locked to an
upright post of a front portion of a base frame by an axle through
central bore. On both sides of the base frame, there are two sets
of exercise devices, each of which comprises a pedal, handlebar and
linkage mechanism composed of the first and second link active link
rods, fixed link rod and crankshaft. When the pedal is pushed
downward, force applied reacts on the first and second active link
rods, causing the flywheel to rotate around the central bore.
Simultaneously, the crankshaft and fixed link rod pivoted on the
first active link rod cause the handlebar to produce back and forth
swings. The pedal, with the first and second active link rods
pivoted on it, makes movement around an oval orbit, causing the
handlebar to swing, thus providing human body with relaxation and
comfort.

Description
FIELD OF THE INVENTION
[0001] This invention relates to an oval orbit exercise bike, which
in particular achieves variable performance in health care. The
feet move around an oval orbit and the pace speed is adjustable
dependent on individual physical condition.
BACKGROUND OF THE INVENTION
[0002] As scientific advances and social prosperity boost greatly
the living standard for the people, high quality of tourism,
sports, meals, and audio and video enjoyment have become
indispensable to their leisure time. For sports, there are indoor
sports and outdoor sports. For indoor sports, there are numerous
kinds of exercise equipment, such pulling machines, chest
expanders, abdominal beds and the universal gyms. However, in all
cases, every equipment responds a recoil action to correspond with
the force applied. In most cases, the recoil action is derived from
the multiple mechanisms. Such mechanisms are not only complicated
in construction, but also frustrating in use.
[0003] For these reasons, the inventor has been working hard on
meticulous study for years and come up with an oval orbit exercise
bike to emphasize the exercise on the feet in an effort to gain
more relief and comfort on body and to train the feet on continuous
walking.
SUMMARY OF THE INVENTION
[0004] The main object the invention intends to achieve is to take
advantage of the eccentric arrangement organized by the second
active link rod and the flywheel, where the second active link
makes circular movement around the central bore of the flywheel,
and the pedal makes an oval time marking movement; simultaneously,
the first active link rod compels the handlebar to swing back and
forth. It not only provides the operator time marking movement, but
also offers relaxation to the whole body.
[0005] Another object of the invention is to use a simplified
mechanism in the greatest benefit to gain the maximum relaxation in
legs. This exercise bike is ergonomically designed with a simple
structure and only a small space is required for installation.
[0006] The objects and features of this invention are expounded in
great details with the aid of advantageous embodiment as
illustrated in the attached drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
[0007] FIG. 1 shows a stereo appearance of an oval orbit exercise
bike of the invention.
[0008] FIG. 2 shows a disassembly of an oval orbit exercise bike of
the invention.
[0009] FIG. 3 shows a side view of an oval orbit exercise bike of
the invention.
[0010] FIG. 4 shows a bird's eye view of an oval orbit exercise
bike of the invention.
[0011] FIG. 5 is a schematic diagram showing the dynamic condition
of an oval orbit exercise bike of the invention.
DETAILED DESCRIPTION OF THE INVENTION
[0012] As shown in FIGS. 1 through 4, the oval orbit exercise bike
includes at least a base frame 1, a flywheel 2, and exercise
devices 3, in which the rear portion of the base frame 1 connects
to a rear platform 12. The front portion of the base frame 1 is an
upright post 11 and a link post 13 with an indicator 6 mounted on
its top. The bottom of the link post 13 is fixed on a lateral axle
14.
[0013] The flywheel 2 has a central bore 21 for fastening itself on
the side of the upright post 11.
[0014] The exercise device 3 comprises a pair of pedal 31 disposed
on each side of the base frame 1, two handlebars 32 and linkage
mechanism 33 composed of a first active rod 331, a second active
rod 332, a link rod 333 and a crankshaft 334. Pins 5 are employed
to link the pedal 31 to the first active rod 331 and the second
active rod 332. The crankshaft 334 of the linkage mechanism 33
connecting to the second active rod 332 is fastened to the
eccentric bore 22 of the flywheel 2 by the crank pin 3342. The link
rod 333 links one end to the crank arm 3341 of the crankshaft 334
and other end to the side arm 3311 of the first active rod 331. The
upper connecting piece 3312 of the first active rod 331 links with
the lateral axle 14 and the handlebars 32. The handlebars 32 have
the handle grips 321 on their tips.
[0015] Please refer to FIGS. 2 through 5, while the pedal 31 is
pushed downward, the force applied reacts on both the first active
rod 331 and the second active rod 332, causing the flywheel 2 to
rotate along the central bore 21; simultaneously the link rod 333
of the crankshaft 334 pivots on the first active rod 331, thus the
handlebars 32 are under force to swing back and forth. In the
meantime, the first active rod 331 and the second active rod 332
are both pivoted on the pedal 31, so the pedal 31 is obliged to
make an oval movement.
[0016] In addition, the first active rod 331 and the second active
rod 332 in the linkage mechanism 33 provide a plurality of lock
holes 3313, 322 for adjusting link angle between the handlebars 32
and the first active rod 331 to obtain the proper pace range of the
pedal 31.
[0017] Furthermore, the second active rod 332 can be designed with
a variable position linking to the flywheel 2 in order to gain the
proper pace of the pedal 31 and to control the curvature of the
oval orbit, so it is ergonomically suitable to individual's
physical requirement.
[0018] The oval orbit exercise bike is very simple in its structure
design, where the eccentricity of the flywheel is utilized to the
maximum on the pedal to produce an oval orbit movement, requiring
only a small space for installation, so it is justified for a grant
of new patent.
