Exercise bike
Abstract
An exercise bike for users to exercise in a face-upward manner
comprises a pedal section, a connecting tube and a base section.
The pedal section locates at the highest point of the exercise bike
and has a counting stopwatch and two pedals that can be adjusted to
change the resistance of stamping. The base can be placed on a
plane and has a pad for lying down and two flexible handles. The
connecting tube locates between and connects the pedal section and
the base section. Some fasteners are installed on the connecting
tube to fasten the connecting tube for fixing the pedal section.
When opening the fasteners, the connecting tube and the pedal
section can be folded to a small unit for storage to conserve the
space.

Description
BACKGROUND OF THE INVENTION
[0001] The present invention relates to an exercise bike,
especially to an exercise bike with a special structure and a
compact style for face-upward stamping exercise that meets the
criteria of originality, practicability and ergonomics.
[0002] Indoor exercise devices, such as treadmill, bike and boat
rowing device, provide the opportunity for sport fans to exercise
in clean and quite rooms without the anxiety of being affected by
weather or the limitation of sports grounds. The indoor exercise
devices are more and more popular in the market.
[0003] Although the conventional indoor exercise devices may have
some advantages, there are difficulties emerge in their practical
use. For example, discordant sound is produced when using some
exercise devices due to the collision of their mechanical members.
Some exercises devices are hard to dismantled after installation
and occupy a lot of indoor spaces due to their big sizes.
SUMMARY OF THE INVENTION
[0004] The object of the present invention is to provide an
exercise bike with new designs, especially an innovated exercise
bike with which users can exercise fully in a face-upward manner.
The exercise bike of the invention meets the criteria of
originality, practicability and ergonomics and is also suitable for
both ordinary users and the people who cannot exercise in a
standing manner.
[0005] Another object of the present invention is to provide an
exercise bike with a special design for the connection of its basic
members so that the exercise bike is not only easily used by users,
but also folded easily and rapidly to a small unit for storage to
conserve the space.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0015] As shown in FIGS. 1 and 2, the exercise bike of the present
invention comprises a pedal section 10, a connecting tube 20 and a
base 30 and is used for exercising in a face-upward manner.
[0016] FIGS. 3 and 4 show the structure of the pedal section 10.
The pedal section 10 comprises a wheel seat 11, a free wheel 12
within the wheel seat 11, a housing 14 surrounding and covering the
wheel seat 11, and a wheel axle 13 piercing through the housing 14,
wheel seat 11 and free wheel 12. Each end of the wheel axle 13 has
a rotating arm 18 and a pedal 19 with which users can stamp the
pedal 19 with their feet to drive the free wheel 12 rotating. A
brake plate 15 and an adjusting button 16 are installed on the
upper part of the wheel seat11. Rotating the adjusting button 16
can push the brake plate 15 downward to touch the free wheel 12 and
change the resistance of stamping the pedal 19. A stopwatch 17 is
installed at the front of the housing 14 to sensor the rotation of
the free wheel 12 and show the time, distance and other data of the
stamping.
[0017] FIGS. 1, 3 and 5 show the structure of the connecting tube
20. The connecting tube 20 comprises a horizontal tube 21 fixed on
the tube body with a bolt, so that the horizontal tube 21 can be
positioned laterally or adjusted to be vertical when folding the
exercise bike. The connecting tube 20 also comprises a press board
22 fixed on the connecting tube 20 at the bottom of the horizontal
tube 21 with a bolt. An arc cover 23 is installed on the upper part
of the pressboard 22 and presses a frame fastener 24, so that the
frame fastener 24 can rotate around the arc axis of the arc cover
23 as its axis. As shown in FIGS. 6 and 7, a screwing button 25 is
installed in the middle of the end of the frame fastener 24 and can
screws on the second U-shape base 33 of the base section 30 to
position the connecting tube 20. The upper part of the connecting
tube 20 is integrated and connected to the pedal section 10 and the
lower part of the connecting tube 20 is installed with a pivot 26
installed on the positioning tube 34 of the base section 30
described below. The connecting tube 20 is positioned vertically
and supports the pedal section 10 to its highest position (FIG. 1)
or folded together with the pedal section 10 to form a small unit
for storage (as shown by the dotted line in FIG. 8).
[0018] As shown in FIGS. 1, 2 and 5, the base section 30 can be
placed on a plane. The base section 30 has a set of parallel base
tubes 31 with a first U-shape tube 32 at the front and a
positioning tube 34 in the middle. A second U-shape tube 33 is
installed between the first U-shape tube 32 and the positioning
tube 34. A fixed plate 35 is installed in the middle of the bottom
of the second U-shape tube 33 and has a threaded opening 36 for the
screwing button 25 to screw through. A U-shape trough 37 is
arranged in the middle at the rear end of the second U-shape tube
33 with a backward opening to accommodate the connecting tube 20. A
U-shape through 38 is arranged in the middle of the positioning
tube 34 with a forward opening to accommodate the pivot 26 at the
lower part of the connecting tube 20. The rear part of the base
tube 31 is designed as two detachable sets with two pads 39 being
placed on the rear part of the base tube 31 for users to lie down.
Each one spring 41 and handle 40 connected with a connecting ring
42 is installed on each side of the base tube 31 respectively as an
auxiliary device for users to hold with hands to increase the
stability when exerting force with the waists.
[0019] FIG. 1 shows the exercise bike after the combination. When
operating the exercise bike, the user lies down on the pad 39 of
the base section 30 with each foot on each one pedal 19 of the left
and right side of the pedal section 10. The user can pillow the
head on the hands or hold both handles 40 on each side of the base
section 30 to increase the stability. The user can adjust the
adjusting button 16 at the upper part of the pedal section 10 to
change the resistance of stamping for better exercising effect.
[0020] The user can also place the knees on the horizontal tube 21,
hook the first U-shape tube 32 with the ankles and pillow the head
on the hands or hold the handles 40 to change the posture for other
sit-ups.
[0021] After the exercising, the user can fold the invented
exercise bike to a small unit for easy storage or unscrew related
bolts to dismantle the whole exercise bike to individual members
for easy packaging and transport, as shown in the FIG. 8.
[0022] The exercise bike of the invention can be changed to a
certain extent in fabrication. For example, in addition to the
round shape shown in the preferred embodiment, the sectional shape
of the tube members of the invented exercise bike can be flat and
round, elongated round, square or rectangular or any combinations
of the shapes without any adverse effect on its functions.
[0023] The designed structure of the invented exercise bike is not
complicated, on the contrary, it is easy for operation, creates
multiple exercising effects and can be folded to a small unit for
easy storage. Especially, the present invention provides an
opportunity for exercising in a face-upward manner and, therefore,
the exercise bike is suitable not only for ordinary users, but also
for the people who cannot exercise in a standing manner due to the
wounds or other handicaps in their bodies.
