Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The invention relates to exercise equipment and more
particularly to an exercise device comprising a length adjustable
leg, a fixed length leg pivotably secured to the length adjustable
leg, and a sliding assembly slidable along the fixed length leg so
that a user's targeted muscles, such as the muscles of the hands,
the abdominal muscles, and the muscles of the back can be enhanced
when the user is kneed on the sliding assembly and moving back and
forth along the fixed length leg while holding handlebars.
[0003] 2. Description of Related Art
[0004] The fitness desire captivating the attention of increasing
number of people throughout the world has spawned an endless array
of exercise equipment. For example, there are exercisers for
strengthening a user's target muscles such as muscles of the back,
the bicep, the abdominal muscles, etc.
[0005] Pull-up is a very popular form of exercise for a long time.
It typically refers to a closed-chain bodyweight movement where the
body is suspended by the arms gripped by the hands, and pulled up
with muscular effort. As this happens, the wrists remain in neutral
position, the elbows flex, and the shoulder extends to bring the
elbows to. The exercise often targets the latissimus dorsi muscle
in the back along with many other assisting muscles.
[0006] Unfortunately, in often times a person has to go to a health
club or park to find a bar for exercise purposes. This is not
convenient. Thus, the need for improvement still exists.

[0007] It is therefore one object of the invention to provide an
exercise device comprising a frame assembly comprising a first leg
including a stop member proximate a bottom end, and a mounting
member at a top end; and a second leg inclined at an angle with
respect to the first leg and comprising a support tube including a
first end hole facing the first leg and a second end hole opposite
to the first end hole, a sliding tube slidably put on the support
tube and having a top end pivotably secured to the mounting member,
the sliding tube including a plurality of first holes facing the
first leg and a plurality of second holes opposite to the first
holes, and a resilient detent disposed in the support tube and
including two end projections wherein one projection passes through
the first end hole into the aligned first hole to be locked and the
other projection passes through the second end hole into the
aligned second hole to be locked, and wherein the projections can
be pressed toward each other to clear the first hole and the second
hole respectively so as to be capable of sliding the sliding tube
to lock the projections in another pair of the first and second
holes respectively; two opposite handlebars each including a
padding member at one end proximate the mounting member; and a
sliding assembly comprising a sliding member slidably mounted on
the first leg and being capable of sliding in a range from a

DETAILED DESCRIPTION OF THE INVENTION
[0014] Referring to FIGS. 1 to 5, an exercise device in accordance
with the invention comprises the following components as discussed
in detail below.
[0015] A frame assembly 1 comprises a T-shaped first leg 11 and a
T-shaped second leg 12 having a top end pivotably secured to a top
end of the first leg 11. The top end of the first leg 11 is formed
as a mounting member 10 with the top end of the second leg 12
pivotably secured thereto. The first leg 11 has a stop member 111
provided proximate the bottom end. In an operative position, both
the first leg 11 and the second leg 12 are supported by the ground
and the first leg 11 is inclined at an angle with respect to the
second leg 12 and vice versa.
[0016] The first leg 11 is fixed in length while the second leg 12
is length adjustable. The second leg 12 comprises a T-shaped
support tube 122 and a sliding tube 121 slidably put on the support
tube 122 as detailed below. The upright portion of the support tube
122 has a substantially rectangular cross-section and the sliding
tube 121 also has same shape. The sliding tube 121 comprises a
plurality of holes 123A on a surface facing the first leg 11 and a
plurality of holes 123B on another surface opposite to the surface
formed with the holes 123A. Correspondingly, the support tube 122
comprises an end hole 124A on a surface facing the first leg 11 and
an end hole 124B on another surface opposite to the surface formed
with the end hole 124A. The second leg 12 further comprises a bent,
resilient detent 125 including two projections 126 proximate both
ends respectively in which one projection 126 passes through the
end hole 124A into the aligned hole 123A to be locked and the other
projection 126 passes through the end hole 124B into the aligned
hole 123B to be locked (i.e., the second leg 12 being locked) as
shown in FIG. 4.
[0017] In a length adjustment operation of the second leg 12, a
user may use one hand to press both the projections 126 toward each
other (i.e., the detent 125 being elastically compressed and
energized) until both the projections 126 clear the hole 123A and
the hole 123B respectively (i.e., the sliding tube 121 being
unlocked). Next, the user may use the other hand to pull the
sliding tube 121 until a desired pair of holes 123A and 123B are
aligned with the pair of end holes 124A and 124B. Next, the detent
125 immediately releases its stored elastic force to expand the
projections 126 into the holes 123A and 123B respectively to be
locked.
[0018] Note that above is a multiple-step operation if the target
holes 123A and 123B are not the ones immediately next to the holes
123A and 123B which are previously aligned with the end holes 124A
and 124B respectively. The inclined angle of the first leg 11 with
respect to the second leg 12 is also changed as a result of the
length adjustment operation of the second leg 12.
[0019] The frame assembly 1 further comprises two opposite bent
handlebars 101 each having a padding member 102 at one end
proximate the mounting member 10. The elbows of a user may rest
against the padding members 102 during an exercise.
[0020] The sliding assembly 2 is adapted to slide along the first
leg 11 in a range about from a position near the mounting member 10
to the stop member 111. In detail, the sliding assembly 2 comprises
an intermediate sliding member 21, a front grooved wheel 23A
rotatably mounted on a front end of the bottom of the sliding
member 21 and adapted to roll on the first leg 11, a rear grooved
wheel 23B rotatably mounted on a rear end of the bottom of the
sliding member 21 and adapted to roll on the first leg 11, and an
intermediate grooved wheel 25 rotatably mounted on an intermediate
portion of the bottom of the sliding member 21 and adapted to roll
on the bottom of the first leg 11. Thus, the sliding member 21 is
adapted to slide along the first leg 11 which is served as
rail.
[0021] The sliding assembly 2 further comprises a left knee rest 22
formed of padding material and a right knee rest 24 formed of
padding material. The left and right knee rests 22 and 24 are
secured to both sides of the sliding member 21 respectively. A
front axis 221 is provided to pass through one side of the sliding
member 21 and through the other side thereof. A rear axis 241
parallel to the front axis 221 is provided to pass through one side
of the sliding member 21 and through the other side thereof. The
left knee rest 22 is secured to both the first and second axes 221
and 241 and comprises an intermediate recess 222. Likewise, the
right knee rest 24 as a mirror image of the left knee rest 22 is
also secured to both the first and second axes 221 and 241 and
comprises an intermediate recess 242.
[0022] Prior to exercise, a user may adjust the inclined angle of
the first leg 11 with respect to the second leg 12 in a way
discussed in above paragraphs. An exercise using the exercise
device of the invention will be discussed in detail below by
referring to FIG. 5 specifically. First, both hands of a user hold
the handlebars 101 with the elbows rested against the padding
members 102. Also, the knees are rested on the recesses 222 and 242
respectively. Thereafter, the legs may exert a force on the left
and right knee rests 22 and 24 to slide the sliding member 21 along
the first leg 11 (i.e., the grooved wheels 23A, 23B and 25 rolling
on the first leg 11) back and forth. In one extremity, the sliding
assembly 2 reaches a position near the mounting member 10 and in
the other extremity, the sliding assembly 2 is stopped by the stop
member 111. It is envisaged by the invention that the a user's
targeted muscles, such as the muscles of the hands, the abdominal
muscles, and the muscles of the back can be enhanced using the
exercise device.
[0023] While the invention has been described in terms of preferred
embodiments, those skilled in the art will recognize that the
invention can be practiced with modifications within the spirit and
scope of the appended claims.
