[0002] The present invention relates to an exercise apparatus,
especially to a rope pulling exercise apparatus with variable
resistance.
[0003] 2. Description of the Prior Art(s)
[0004] With progress of the society, people's activities are more
and more depending on machines and technical products. The people
without regular and enough exercises have reduced muscle strength
and mass. Therefore, the people nowadays should have to pay
attention to exercise.
[0005] Diseases of affluence occurring on the modern people are
relevant to if the people exercise regularly. Mentally, exercise is
helpful in reducing stress and tiredness. As the people are in good
moods, the people are also good in interpersonal relationships. To
have habits of exercise allows the people to have high self-esteem
and have confidence on themselves. Physically, exercise is helpful
in increasing metabolism, improving cardiovascular health, reducing
incidence of heart disease and apoplexy, and lowering cholesterol
and blood pressure.
[0006] Moreover, through weight training, muscles can be trained to
support bones and joints and to protect important organs of a human
body, so the people become strong and health. Since doing exercises
is not only good for mental and physical health but also protects a
human body, in urban areas with high population density, the people
go to exercise in fitness clubs, sports centers or gymnasiums.
However, since fitness equipments in the fitness clubs, the sports
centers or the gymnasiums are almost the same, the people might
feel bored over time, and lose their desire to keep on
exercising.
[0007] To overcome the shortcomings, the present invention provides
a rope pulling exercise apparatus with variable resistance to
mitigate or obviate the aforementioned problems.
SUMMARY OF THE INVENTION
[0008] The main objective of the present invention is to provide a
rope pulling exercise apparatus with variable resistance. The rope
pulling exercise apparatus has a main supporting frame, a rotary
cylinder assembly, a rotary wheel, a driving device and a
resistance generating device. The rotary cylinder assembly is

driving wheel coaxially mounted on the rotary cylinder, a driven
wheel coaxially mounted on the rotary wheel, aligning with the
driving wheel and being smaller than the driving wheel in radius,
and a transmission belt mounted around the driving wheel and the
driven wheel. The resistance generating device is disposed adjacent
to a peripheral surface of the rotary wheel and selectively
resisting rotation of the rotary wheel.
[0009] When a user pulls the pull-rope of the rotary cylinder
assembly, the rotary cylinder rotates accordingly and the rotary
cylinder rotates the rotary wheel through the driving device. The
resistance generating device applies rotational resistance to the
rotary wheel. Thus, the user can pull the pull-rope back and forth
to train himself The rope pulling exercise apparatus provides the
user one more option on choosing fitness equipments, and increases
the user's desire on exercising. Moreover, as the driving wheel is
larger than the driven wheel in radius, the rope pulling exercise
apparatus provides effective fitness effect.

[0028] With further reference to FIGS. 4, 6 and 8, the resistance
generating device 50, 50A, 50B is disposed adjacent to the
peripheral surface of the rotary wheel 30, 30A and selectively
resists rotation of the rotary wheel 30, 30A.
[0029] With reference to FIGS. 3 to 5, in the first preferred
embodiment, the resistance generating device 50 has a band 51, a
magnetic portion 52 and an adjusting member 53. The band 51 has a
fastening end 511, a free end 512 and an inner surface. The
fastening end 511 of the band 51 is securely attached to the first
side support 142 of the mounting bracket 14. The free end 512 of
the band 51 is movable relative to the mounting portion 14211 of
the first mount 1421 of the mounting bracket 14. The inner surface
of the band 51 corresponds to the peripheral surface of the rotary
wheel 30. The magnetic portion 52 is mounted on the inner surface
of the band 51. The adjusting member 53 is rotatably mounted
through the mounting portion 14211 of the first mount 1421 of the
mounting bracket 14 and the free end 512 of the band 51, and
selectively adjust distance defined between the mounting portion
14211 of the first mount 1421 of the mounting bracket 14 and the
free end 512 of the band 51 to allow the band 51 to be close to or
to leave the peripheral surface of the rotary wheel 30. The
adjusting member 53 has a bolt 531 and a knob 532. The bolt 531 is
mounted through the mounting portion 14211 of the first mount 1421
and engages the free end 512 of the band 51. The knob 532 is
mounted on an end of the bolt 531 and is disposed beside the
mounting portion 14211 of the first mount 1421.
[0030] With reference to FIGS. 6 and 7, in a second preferred
embodiment, the first mount 1421 of the first side support 142
further has a fastening portion 14212A. The resistance generating
device 50A has a band 51A and an adjusting member 53A. The band 51A
has a fastening end 511A, a free end 512A and an inner surface. The
fastening end 511A of the band 51A is securely attached to the
fastening portion 14212A of the first mount 1421 of the first side
support 142. The free end 512A of the band 51A corresponds to the
fastening end 511A of the band 51A. A distance defined between the
free end 512A and the fastening end 511A of the band 51A is
adjustable. The inner surface of the band 51A abuts the peripheral
surface of the rotary wheel 30.
[0031] With reference to FIG. 9, in the third preferred embodiment,
the resistance generating device 50B has a band 51B, a resilient
assembly and an adjusting member 53B. The band 51B is mounted
around the rotary wheel 30A and has a fastening end 511B and a free
end 512B. The resilient assembly is mounted on the free end 512B of
the band 51B and has a slider 5122B and a resilient element 5121B.
The resilient element 5212B has two ends each respectively
connected to the free end 512B of the band 51B and the slider

rotatably mounted on the mounting portion 14211, and is mounted
through and engages the slider 5122B. When the bolt 531B of the
adjusting member 53B is rotated, the slider 5122B slides along the
bolt 531B.
[0032] With reference to FIG. 8, the guide wheel assembly 60 is
mounted by the rotary cylinder 21. The pull-rope 23 slidably abuts
the guide wheel assembly 60. Preferably, the guide wheel assembly
60 has two guide wheels 61. The guide wheels 61 are rotatably
disposed adjacent to each other. The pull-rope 23 is mounted and
held between and abuts the guide wheels 61 of the guide wheel
assembly 60.
[0033] The housing 70 is mounted around the mounting bracket 14 of
the main supporting frame 10, the rotary cylinder 21, the rotary
wheel 30, 30A, the driving device 40, the resistance generating
device 50, 50A, 50B and the guide wheel assembly 60. The pull-rope
23 of the rotary cylinder assembly 20 is mounted through the
housing 70 and is partially exposed to exterior of the housing
70.
[0034] With reference to FIGS. 1 and 3, a user can stand or sit on
the cushion 13 of the main supporting frame 10 and pulls the
pull-rope 23 of the rotary cylinder assembly 20 back and forth with
his two hands to train corresponding muscles of his body. When the
pull-rope 23 is pulled, the rotary cylinder 21 rotates accordingly
and the rotary cylinder 21 rotates the rotary wheel 30, 30A through
the driving device 40. Attachment of the resistance generating
device 50, 50A, 50B to the peripheral surface of the rotary wheel
30, 30A can be adjusted in order to adjust rotational resistance
applied to the rotary wheel 30, 30A, so the user can adjust the
rotational resistance applied to the rotary wheel 30, 30A according
to his physical condition and exercise intensity. Moreover, since
the driving wheel 41 is larger than the driven wheel 42 in radius,
a rotational speed of the rotary cylinder 21 is slower than a
rotational speed of the rotary wheel 30, 30A. Whenever the user
pulls the pull-rope 23 to rotate the rotary cylinder 21 to turn a
full circle, the rotary wheel 30, 30A turns more than one circle.
With the rotational resistance that the resistance generating
device 50, 50A, 50B applies to the rotary wheel 30, 30A, a force
that the user apply to the pull-rope 23 to turn the rotary cylinder
20 a full circle and the rotary wheel 30, 30A multiple circles is
larger than a force that the user apply to the pull-rope 23 to turn
each of the rotary cylinder 21 and the rotary wheel 30, 30A a full
circle.
[0035] As shown in FIGS. 4 and 5, in the first preferred
embodiment, the magnetic portion 52 of the resistance generating
device 50 applies magnetic force to restrict rotation of the rotary
wheel 30. Thus, by adjusting the distance defined between the first
mount 1421 of the mounting bracket 14 of the main supporting frame
10 and the free end 512 of the band 51 with the adjusting member
53, a distance defined between the band 51 and the peripheral
surface of the rotary wheel 30 changes accordingly. Consequently,
the rotational resistance applied to the rotary wheel 30 is
adjusted and the rotation of the rotary wheel 30 is restricted.
[0036] As shown in FIGS. 6 and 7, in the second preferred
embodiment, the band 51A is substantially circular. With friction
formed between the band 51A and the rotary wheel 30, the rotation
of the rotary wheel 30 is restricted. Specifically, by adjusting
the distance defined between the free end 512A of the band 51A and
the first mount 1421 of the mounting bracket 14 of the main
supporting frame 10 with the adjusting member 53A, the distance
defined between the band 51A and the peripheral surface of the
rotary wheel 30 changes accordingly. When the free end 512A of the
band 51A leaves the mounting portion 14211, an area that the band
51A contacting the peripheral surface of the rotary wheel 30 is
enlarged. Consequently, the rotary wheel 30 is getting difficult to
be rotated. On the other hand, as the free end 512A of the band 51A
gets close to the mounting portion 14211, the area that the band
51A contacting the peripheral surface of the rotary wheel 30 is
reduced or eliminated. Thus, the rotary wheel 30 can be rotated
easily.
[0037] As shown in FIGS. 9 and 10, by adjusting position of the
slider 5122B on the bolt 531B of the adjusting member 53B, length
of the resilient element 5121B are adjusted. Consequently,
tightness of the band 51B that abuts the rotary wheel 30A, the
rotational resistance applied to the rotary wheel 30A, and a
rotational tendency of the rotary wheel 30A are adjusted
accordingly. Moreover, the guide wheel assembly 60 guides the
pull-rope 23 and prevents the pull-rope 23 from being worn away by
the housing 70.
[0038] The rope pulling exercise apparatus as described has the
following advantages. The resistance generating device 50, 50A, 50B
is disposed around the rotary wheel 30, 30A and applies the
adjustable rotational resistance to the rotary wheel 30, 30A. When
the user pulls the pull-rope 23 of the rotary cylinder assembly 20,
the rotary cylinder 21 rotates accordingly and the rotary cylinder
21 rotates the rotary wheel 30, 30A through the driving device 40.
The resistance generating device 50, 50A, 50B applies the
rotational resistance to the rotary wheel 30, 30A. Thus, the user
can pull the pull-rope 23 back and forth to train himself. The rope
pulling exercise apparatus provides the user one more option on
choosing fitness equipments, and increases the user's desire on
exercising. Moreover, as the driving wheel 41 is larger than the
driven wheel 42 in radius, the rope pulling exercise apparatus
provides effective fitness effect.
[0039] Even though numerous characteristics and advantages of the
present invention have been set forth in the foregoing description,
together with details of the structure and features of the
invention, the disclosure is illustrative only. Changes may be made
in the details, especially in matters of shape, size, and
arrangement of parts within the principles of the invention to the
full extent indicated by the broad general meaning of the terms in
which the appended claims are expressed.
