Description
BACKGROUND OF THE INVENTION
[0001] (1) Field of the Invention
[0002] The present invention relates to a training apparatus and
more particularly to a training apparatus for a bicycle that can
provide a preferred training effect, can reduce the abrasion of
wheels of the bicycle, can reduce the noise in use and can save
space when storing or transporting the training apparatus.
[0003] (2) Description of the Prior Art
[0004] A conventional training apparatus for a bicycle has a base,
three rollers and multiple belts. The rollers are rotatably mounted
on the base at intervals. The belts are mounted between the rollers
to link the rollers with each other. In use, a rear wheel of a
bicycle is mounted between two of the rollers and a front wheel of
the bicycle is mounted on the other one roller. When a person rides
the bicycle, the rear wheel will make the rollers rotating by the
belts to simulate the actual riding status. However, the wheels of
the bicycle are mounted between the rollers of the conventional
training apparatus, the height of the bicycle on the conventional
training apparatus is higher than the actual height of the bicycle
on the ground. Then, the person needs a span to get with the
altitudinal difference between the conventional training apparatus
and the bicycle and this will influence the training effect of the
person. Especially, the wheels of the bicycle are directly mounted
on and abut the rollers and this will increase the abrasion of the
wheels of the bicycle. In addition, the vibration that made from
the rotation between the wheels and the rollers will make noises.
Furthermore, the conventional training apparatus is mounted below
the wheels of the bicycle and has a large volume, then transporting
and carrying the conventional training apparatus is
inconvenient.
[0005] Another conventional training apparatus has a supporting
frame and a resisting roller. The supporting frame has two ends to
hold the wheel axle of the real wheel of the bicycle to support the
rear wheel of the bicycle. The resisting roller is rotatably
mounted on the supporting frame and abuts against the rear wheel.
Then, a person can use the resistance force that provided by the
resisting roller to train. However, the rear wheel of the bicycle
is supported by the supporting frame and is higher than the front
wheel of the bicycle, and this is different from the actual riding
status. Then, the training effect of the person will be influenced
by the simulated riding status. Especially, the rear wheel of the
bicycle is directly mounted on and abuts the resisting roller and
this will increase the abrasion of the rear wheel of the bicycle.
In addition, the vibration that made from the rotation between the
rear wheel and the resisting roller will make noises.
[0006] A training apparatus for a bicycle in accordance with the
present invention mitigates or obviates the aforementioned
problems.
SUMMARY OF THE INVENTION
[0007] The main objective of the present invention is to provide a
training apparatus for a bicycle that can provide a preferred
training effect, can reduce the abrasion of wheels of the bicycle,
can reduce the noise in use and can save space when storing or
transporting the training apparatus.
[0008] The training apparatus for a bicycle has a base, a
transmitting device and a damping device. The base has a holding
mount and a supporting frame. The supporting frame is mounted on
the holding mount. The transmitting device is rotatably mounted on
the base and has an axle assembly, a major belt pulley, a rotating
axle, a minor belt pulley, a belt and a chain wheel group. The axle
assembly is mounted through the supporting frame. The major belt
pulley is rotatably mounted around the axle assembly. The rotating
axle is rotatably mounted through the supporting frame below the
major belt pulley. The minor belt pulley is mounted around the
rotating axle. The belt is mounted around the belt pulleys. The
chain wheel group is rotatably mounted around the axle assembly and
is securely connected to the major belt pulley. The damping device
is mounted on the supporting frame of the base, is mounted around
the rotating axle of the transmitting device ad has a damping
wheel, a magnetizer and an adjusting assembly. The damping wheel is
securely mounted around the rotating axle opposite to the minor
belt pulley. The magnetizer is curved, is movably connected to the
supporting frame around the damping wheel to provide a resistance
force to the damping wheel. The adjusting assembly is connected to
the supporting frame and the magnetizer.
