Fastening device for pedals of exercisers
Abstract
A fastening device on pedals of exercisers includes a first belt
having an end connected to an end of the pedal and a lock assembly
is connected to the other end of the first belt. The lock assembly
includes a base and a pawl which is pivotably connected between two
side walls of the base. A torsion spring is connected between the
pawl and the base. First teeth are defined in an end of the pawl. A
second belt has an end connected to the other end of the pedal and
the other end of the second belt is inserted between the base and
the pawl. Second teeth are defined in a side surface of the second
belt and engaged with the first teeth. The first teeth are
disengaged from the second teeth 212 by pivoting an operation end
of the pawl such that the second belt can be quickly and
conveniently adjusted to a desired position.

Description
FIELD OF THE INVENTION
[0001] The present invention relates to a fastening device for
securing users' feet on the pedals and the fastening device allows
the users to quickly and conveniently adjust it.
BACKGROUND OF THE INVENTION
[0002] A conventional fastening device for securing users' feet on
pedals of exercisers is shown in FIGS. 1 and 2 and generally
includes two T-shaped protrusions 11, 12 on two ends of the pedal 1
and a fastening belt 15 having holes 16, 17 defined therethrough so
that one of the holes 16 close to one end of the belt 15 is engaged
with the protrusion 11, and one of the holes 17 close to the other
end of the belt 15 is engaged with the other protrusion 12. The
user's foot is then secured on the pedal 1 by the fastening belt
15. The user has to pull the fastening belt 15 to enlarge the size
of the holes 16, 17 so as to successfully mount to the protrusions
11, 12 and this requires a lot of force. This increases the time
required to adjust the fastening belt 15. The distance between the
holes 16, 17 limits the adjustment of the fastening belt 15 so that
the conventional fastening device cannot meet requirement of
different users.
[0003] The present invention intends to provide a fastening device
that is easily to operate and can be adjusted at small scale.
SUMMARY OF THE INVENTION
[0004] In accordance with one aspect of the present invention,
there is provided a fastening device on pedals and the device
comprises a first belt having an end connected to an end of the
pedal and a lock assembly is connected to the other end of the
first belt. The lock assembly comprises a base and a pawl which is
pivotably connected to the base. A torsion spring is connected
between the pawl and the base. First teeth are defined in an end of
the pawl.
[0005] A second belt has an end connected to the other end of the
pedal and the other end of the second belt is inserted between the
base and the pawl. Second teeth are defined in a side surface of
the second belt and are engaged with the first teeth.
[0006] The present invention will become more obvious from the
following description when taken in connection with the
accompanying drawings which show, for purposes of illustration
only, a preferred embodiment in accordance with the present
invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0017] Referring to FIGS. 3 to 5, the fastening device on pedals 1
of the present invention comprises a first belt 20 having first
holes 201 defined in the first end thereof and one of the first
holes 201 is engaged with a protrusion 10 on the pedal 1. A lock
assembly 3 is connected to the other end of the first belt 20. The
lock assembly 3 comprises a base 30 and a pawl 32 which is
pivotably connected between two side walls 301 of the base 30 by
extending a pin 5 through two holes 302 defined respectively in two
side walls 301 of the base 30 and an intermediate portion of the
pawl 32. The pawl 32 includes an operation end 321 and an engaging
end which has first teeth 320. The intermediate portion is located
between the operation end 321 and the engaging end so that when
pushing the operation end 321, the engaging end is pivoted away
from the base 30. A torsion spring 31 is connected between the pawl
32 and the base 30.
[0018] A second belt 21 has a first end with a plurality of holes
211 and one of which is engaged with a protrusion 11 on the pedal
1. A second end of the second belt 21 is inserted between the base
30 and the pawl 32. Second teeth 212 are defined in a side surface
of the second belt 21 and engaged with the first teeth 320 of the
pawl 32 so that the user's foot is positioned between the pedal 1
and the first belt 20 and the second belt 21.
[0019] As shown in FIGS. 6 and 7, the user may also adjust the
first belt 20 by engaging the protrusion 10 with another hole 201
so as to allow a larger foot positioned by the fastening device of
the present invention.
[0020] FIG. 8 shows that the second belt 21 can be integrally
connected to the pedal 1. FIG. 9 shows that both the first belt 20
and the second belt 21 can be fixed to the pedal 1 by a bolt 6.
[0021] Referring to FIGS. 10 and 11, another embodiment of the
fastening device of the present invention comprises a first belt 20
having first holes 201 defined in a first end thereof and one of
the first holes 201 is engaged with a protrusion 10 on the pedal 1.
A lock assembly 3 is connected to a second end of the first belt
20. The lock assembly 3 comprises a base 30 and a pawl 32 which is
pivotably connected between two side walls 301 of the base 30 by
extending a pin 5 through two holes 302 defined respectively in two
side walls 301 of the base 30 and an intermediate portion of the
pawl 32. The pawl 32 includes an operation end 321 and an engaging
end which has first teeth 320. The intermediate portion is located
between the operation end 321 and the engaging end so that when
pushing the operation end 321, the engaging end is pivoted away
from the base 30. A torsion spring 31 is connected between the pawl
32 and the base 30.
[0022] A pusher 33 is pivotably connected between the two side
walls 301 by extending a pin 50 through two slots 303 in the two
side walls 301 and the pusher 33. Another torsion spring 31 is
connected between the pusher 33 and the base 30. The pusher 33
includes push teeth 330 defined in an end thereof and a handle end
331, wherein the pin 50 is located between the handle end 331 and
the push teeth 330.
[0023] A second belt 21 has a hole 211 defined in an end thereof
and the hole 211 is engaged with a protrusion 11 on the pedal 1.
The other end of the second belt 21 is inserted between the base
30, the pawl 32 and the pusher 33. Second teeth 212 are defined in
a side surface of the second belt 21 and engaged with the first
teeth 320 of the pawl 32.
[0024] Referring to FIGS. 12 to 14, the push teeth 330 are engaged
with the second teeth 212 of the second belt 21 by pivoting the
pusher 33 clockwise so as to push the second belt 21 toward the
pawl 32. Due to the profile of the first teeth 320, the second belt
21 can move over the first teeth 320. The pin 50 is moved between
two ends of the slots 303 when reciprocally operating the push
teeth 330 to push the second belt 21. The second belt 21 is
adjusted by repeatedly operating the pusher 33 till a desired
tightness is reached. The pawl 32 and the pusher 33 can be pivoted
to disengage the first teeth 320 and the push teeth 330 from the
second teeth 212 on the second belt 21 by pushing the operation end
321 and the handle end 331 respectively.
[0025] While we have shown and described the embodiment in
accordance with the present invention, it should be clear to those
skilled in the art that further embodiments may be made without
departing from the scope of the present invention.
