Description
FIELD OF THE INVENTION
[0001] The present invention relates to an exercise training
device, and more particularly to a swingable exercise bike.
BACKGROUND OF THE INVENTION
[0002] According to the trend in sports, people may go to the gym
or buy an exercise bike at home for exercise. The bike body of most
conventional exercise bikes is stationary, that is, the bike body
is fixed to a base. The user stably rides on the bike body and
continuously treads to generate a sports effect.
[0003] The pedaling action of the exercise bike described above is
slightly monotonous, and the user is prone to be inpatient and
cannot continue to exercise. Therefore, another exercise bike has
been developed on the market. As shown in FIG. 5, a bike body 41 is
pivotally connected to a pivot portion 42 of a base 4, allowing the
bike body 41 to swing left and right relative to the base 4, so
that the user can experience the actual feeling of riding a bike to
enhance the fun during the exercise.
[0004] For the safety during the exercise, the base 4 is provided
with elastic members 43 at both sides of the pivot portion 42 as a
cushion. When the bike body swings left and right, it is pressed
against the elastic member 43 on the corresponding side to obtain
the cushioning resistance, so as to prevent the user from falling
and being injured. In the above-mentioned conventional structure,
the elastic member 43 is disposed in an upright manner. When it is
pressed, a deformation in the height direction is generated to
provide a cushioning resistance in the height direction. But, the
swinging motion of the bike body 41 is performed along a curved
trajectory. It is difficult for the upright elastic member 43 to
stably support the swinging bike body 41, with safety concerns.
Accordingly, the inventor of the present invention has devoted
himself based on his many years of practical experiences to solve
these problems.
SUMMARY OF THE INVENTION
[0005] The primary object of the present invention is to provide a
swingable exercise bike. A cushion device for cushioning the swing
of a bike body provides horizontal support, thereby ensuring that
the bike body obtains stable support to prevent the user from
falling and being injured.
[0006] In order to achieve the aforesaid object, a swingable
exercise bike is provided. The swingable exercise bike comprises a
base, a supporting mechanism, and a cushion device. The base has a
first pivot portion for a bike body to be pivotally connected to
the first pivot portion so that the bike body is able to swing left
and right relative to the base. The supporting mechanism includes
two first connecting rods located at left and right sides of the
first pivot portion. The first connecting rods each have one end
pivotally connected to the base and another end extending in a
height direction and pivotally connected to a second connecting
rod. The second connecting rod is further pivotally connected to
the bike body. When the bike body swings left and right, the first
connecting rods and the second linking rods are pivoted. The
cushion device is disposed in a horizontal direction and has two
ends respectively connected to the two second connecting rods for
generating damping when the two second connecting rods are pivoted
by the bike body.
[0007] In an embodiment, the base is provided with second pivot
portions at the left and right sides of the first pivot portion for
pivotal connection of the first connecting rods. The second
connecting rod has a length less than a distance between the first
pivot portion and the second pivot portion.
[0008] In an embodiment, pivotal positions at which the two second
connecting rods of the supporting mechanism are connected to the
bike body are at a same height.
[0009] In an embodiment, the cushion device includes a damper and
two supports. The two supports are located at the left and right
sides of the first pivot portion and fixed to the second connecting
rods, respectively. Two ends of the damper are pivotally connected
to the two supports, respectively.

[0013] FIG. 5 a planar view of the prior art.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0014] Embodiments of the present invention will now be described,
by way of example only, with reference to the accompanying
drawings.
[0015] Referring to FIG. 1 and FIG. 2, the present invention
discloses a swingable exercise bike, comprising a bike body 11 and
a base 1. The bike body 11 is a flywheel structure of any type in
the prior art. The bike body 11 comprises a frame, a seat, an
armrest, a rotating wheel, a pedal, a resistance wheel (not shown),
and so on. The front and rear ends of the base 1 are provided with
first pivot portions 12, respectively. The bike body 11 is
pivotally connected to the first pivot portions 12, so that the
bike body 11 is able to swing left and right relative to the base
1.
[0016] The front and rear ends of the base 1 are provided with
supporting mechanisms 2 corresponding to the first pivot portions
12, respectively. As shown in FIG. 2, each supporting mechanism 2
includes two first connecting rods 21A, 21B located at left and
right sides of the first pivot portion 12. The base 1 is provided
with second pivot portions 13A, 13B at the left and right sides of
the first pivot portion 12. The first connecting rods 21A, 21B each
have one end pivotally connected to the second pivot portion 13A,
13B and another end extending in the height direction and pivotally
connected to a second connecting rod 22A, 22B. Another end of the
second connecting rod 22A, 22B is pivotally connected to the bike
body 11. The pivotal positions at which the two second connecting
rods 22A, 22B are connected to the bike body 11 are at the same
height. In this embodiment, the length of the second connecting rod
22A, 22B is less than the distance between the first pivot portion
12 and the second pivot portion 13A, 13B. Thereby, the first
connecting rod 21A, 21B is set to be inclined toward the first
pivot portion 12 when the bike body 11 is not swung. In detail, the
first connecting rod 21A located at the left side of the first
pivot portion 12 is inclined toward the right side, and the first
connecting rod 21B located at the right side of the first pivot
portion 12 is inclined toward the left side. With the above
structure, when the bike body 11 swings left and right relative to
the base 1, the second connecting rods 22A, 22B are driven to link
the first connecting rods 21A, 21B to generate a pivot.
[0017] Furthermore, the supporting mechanism 2 is provided with a
cushion device 3. The cushion device 3 includes a damper 31 and two
supports 32A, 32B. The two supports 32A, 32B are located at the
left and right sides of the first pivot portion 12, respectively.
The bottom ends of the two supports 32A, 32B are fixed to the
second connecting rods 22A, 22B, respectively. The top ends of the
two supports 32A, 32B extend upwardly. Two ends of the damper 31
are pivotally connected to the top ends of the two supports 32A,
32B, respectively. The damper 31 is disposed in the horizontal
direction and is a device that can change in length, thereby
absorbing the applied force and generating a cushioning effect.
When the bike body 11 swings left and right relative to the base 1,
the second connecting rods 22A, 22B are pivoted by the bike body 11
to drive the two supports 32A, 32B to change the distance between
the two supports 32A, 32B, thereby compressing or extending the
damper 31 to provide a cushioning effect.
[0018] With the above configuration, when the user swings the bike
body 11 left, as shown in FIG. 3, the bike body 11 pushes and pulls
the second connecting rods 22A, 22B at the two sides thereof, so
that the two supports 32A, 32B are linked to compress or extend the
damper 31. Accordingly, the action of swinging the bike body 11 to
the left side is buffered, and the swing can be performed more
stably to prevent the user from falling and being injured. Since
the bike body 11 swings to the left side to pivot the second
connecting rods 22A, 22B, the first connecting rods 21A, 21B are
also pivoted. The first connecting rod 21A located at the left side
is linked to pivot left, but does not swing beyond the left of its
axis, thereby making the swing of the bike body 11 more stable and
being supported.
[0019] On the other hand, when the user swings the bike body 11
right, as shown in FIG. 4, the bike body 11 pushes and pulls the
second connecting rods 22A, 22B at the two sides thereof, so that
the two supports 32A, 32B are linked to compress or extend the
damper 31. Accordingly, the action of swinging the bike body 11 to
the right side is buffered, and the swing can be performed more
stably to prevent the user from falling and being injured. Since
the bike body 11 swings to the right side to pivot the second
connecting rods 22A, 22B, the first connecting rods 21A, 21B are
also pivoted. The first connecting rod 21A located at the right
side is linked to pivot right, but does not swing beyond the right
of its axis, thereby making the swing of the bike body 11 more
stable and being supported.
[0020] Although particular embodiments of the present 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 present invention. Accordingly, the
present invention is not to be limited except as by the appended
claims.
