Pull-up and Abdominal Exerciser
Abstract
An exerciser includes a base having a first frame and a second
frame which is pivotably connected to the first frame, and a slide
device. The first and second frames are arranged to have an angle
therebetween. The slide device has a damper and a roller is
connected to the slide rod so as to move on the second frame. The
users put the base on the floor to use the exerciser as a pull-up
exerciser. The users can also overlap the first and second frames
and put the first and second frames on the floor to use as an
abdominal exerciser. The damper generates different resistance to
obtain different exercising levels.

Description
FIELD OF THE INVENTION
[0001] The present invention relates to an exerciser, and more
particularly, to an exercise with pull-up and abdominal training
features.
BACKGROUND OF THE INVENTION
[0002] Many conventional exercisers provide different function for
training and/or exercising different parts of the users' muscles.
One of the welcomed exercisers is the pull-up exerciser which
trains the muscles on the back and the arms. The pull-up exerciser
includes a bar which is located above the user's chest and the user
holds the bar and pulls the body upward by the arms. By repeatedly
pulling the body upward, the muscles of the back and the arms are
exercised. However, the users have to visit gyms or parks, rather
than at home, to use the pull-up exerciser and this is inconvenient
for the users.
[0003] The other welcomed exerciser is the abdominal training
exerciser which includes a roller with two grips on two ends
thereof, and the user holes the two grips and rolls the roller
along rails so that the body extends forward until the body is bent
like a triangle, and then the user pulls the roller back. By
repeatedly operating the roller, the abdominal muscles are
exercised. However, the resistance of the roller cannot be
adjusted.
[0004] The present invention intends to provide a pull-up and
abdominal exerciser which improves the shortcomings of the
conventional exercisers.
SUMMARY OF THE INVENTION
[0005] The present invention relates to an exerciser and comprises
a base having a first frame and a second frame which has a pivotal
end so as to be pivotably connected to the first frame. The first
and second frames stand on a floor and an angle is defined between
the first and second frames. The second frame has a free end
located in opposite to the pivotal end. A first grip portion and a
bar are located at the pivotal end. A slide device comprises a
slide rod and a damper, wherein the slide rod has a second grip
portion extending from two ends thereof and a roller is connected
to the lower end of the slide rod. The slide rod is slidably
movable along the second frame. When using as an abdominal
exerciser, the first and second frames overlapped to each other and
the second frame faces upward. The damper has the first end fixed
to the free end of the second frame, and the second end of the
damper trains a pulley on the pivotal end and is fixed to a fixing
member on the slide rod. When using as an abdominal exerciser, the
user holds the second grip portion on the slide rod and the user's
knees contact against the bar on the pivotal end to move the slide
rod. When using as a pull-up exerciser, the first and second frames
stand on the floor with an angle defined between the first and
second frames, and the two ends of the damper are fixed to the free
end and the pivotal end respectively. The user holds the first grip
portion and the user's knees contact against the slide rod to pull
user's body upward while the slide rod slides.
[0006] The primary object of the present invention is to provide an
exerciser which has two different exercising functions and the
users can operate the exerciser as an abdominal exerciser or a
pull-up exerciser.
[0007] 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
[0013] Referring to FIGS. 1 to 5, the exerciser of the present
invention comprises a base 1 having a first frame 11 and a second
frame 12 which has a pivotal end 10 pivotably connected to the
first frame 11. The first and second frames 11, 12 can be
overlapped to each other and put on the floor, or to stand on the
floor by an angle defined between the first and second frames 11,
12. The first frame 11 is a retractable frame and an adjustment
member 13 is connected to the pivotal position between the first
and second frames 11, 12 so as to adjust the angle between the
first and second frames 11, 12. The adjustment member 13 comprises
a semi-circular disk 131 with multiple holes and a pin 133 extends
through one of the holes to fix the angle between the first and
second frames 11, 12. The second frame 12 has a free end 120
located in opposite to the pivotal end 10. A first grip portion 101
and a bar 102 are located at the pivotal end 10. A slide device 2
includes a slide rod 21 and a damper 23. The slide rod 21 has a
second grip portion 201 extending from two ends thereof. A roller
211 is connected to the lower end of the slide rod 21 so that the
slide rod 21 is slidably movable along the second frame 12. The
slide device 2 comprises an installation rod 25 which is parallel
to the slide rod 21 and a first distance 251 is defined between the
installation rod 25 and the slide rod 21. The first distance 251
accommodates the user's knees when the user uses the exerciser as a
pull-up exerciser. The installation rod 25 can be disengaged from
the second frame 12 and is connected to the pivotal end 10 and
parallel to the bar 102. A second distance 252 is defined between
the installation rod 25 on the pivotal end 10 and the bar 102. The
second distance 252 accommodates the user's knees when the user
uses the exerciser as an abdominal exerciser.
[0014] When using as an abdominal exerciser, the first and second
frames 11, 12 are overlapped to each other and the second frame 12
faces upward. The damper 23 has a first end fixed to the free end
120 of the second frame 12, and a second end of the damper 23
trains through a pulley 127 on the pivotal end 10 and is fixed to a
fixing member 212 on the slide rod 21. The user holds the second
grip portion 210 on the slide rod 21 and the user's knees contact
against the bar 102 on the pivotal end 10 to move the slide rod 21
by using the arms and the waist. The slide rod 21 has the damper 23
so that the user has to overcome the resistance from the damper 23
to move the slide rod 21. When releasing the second grip portion
210, the damper 23 pulls the slide rod 21 back to its original
position. By repeatedly operating, the muscles of the abdominal
portion are exercised.
[0015] When using as a pull-up exerciser, the first and second
frames 11, 12 stand on the floor with an angle defined between the
first and second frames 11, 12. The two ends of the damper 23 are
fixed to the free end 120 and the pivotal end 10 respectively. The
user holds the first grip portion 101 and the user's knees contact
against the slide rod 21 to pull user's body upward while the slide
rod 21 slides by the user's knees. By repeatedly operating, the
muscles of the arms and the back are exercised.
[0016] The bar 102, the slide rod 21 and the installation rod 25
are wrapped with soft material so as to protect the user's knees
when the knees are accommodated in the first or second distances
251, 252.
[0017] The exerciser can switch the two different functions as
mentioned above and the exerciser can be used at home. By using the
damper 23, different levels of exercising are obtained.
[0018] 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.
