Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates generally to exercise
apparatuses, and more particularly to a push-up trainer.
[0003] 2. Description of the Related Art
[0004] A conventional push-up trainer 80, as shown in FIG. 5, is
comprised of an elongated base 81, a supporter 82, two pressing
bars 83, and a guiding member 84. The elongated base 81 includes
two upholding members 85 extending upwards. The supporter 82
includes a cushion 86 and two bearing bars 87 mounted to a bottom
side of the cushion 86. Each of the two pressing bars 83 is
pivotably connected to an apex of the upholding member 85,
including an end pivotably mounted to a distal end of each bearing
bar 87 and the other end provided with a handlebar 88. The guiding
member 84 includes a first section 91 and a second section 92,
which both are pivotably connected with each other to be
collapsible relatively to each other. The guiding member 84 is
mounted between the base 81 and the supporter 82, having the first
section 91 connected to the cushion 86 and the second section 92
pivotably connected to the base 81, for keeping the up-down
movement of the supporter 82.
[0005] If the user intends to operate the push-up trainer 80 for
push-up exercise, the user will hold the handlebars 88 respectively
by the user's hands, let the user's chest lie against the cushion
86, and push and pull the two pressing bars 83 repeatedly to
generate leverage; meanwhile, the leverage drives the bearing bars
87 and the cushion 86 for up-down movement to further move the
user's body up and down.
[0006] However, the conventional push-up trainer 80 is structurally
complex, having numerous component parts, and the user is subject
to injury incurred by the collapsible guiding member 84. In
addition, different users have different arm length or different
length of two outstretched arms, and the distance respectively
between the two handlebars 88 and between each handlebar 88 and the
cushion 86 is fixed, such that the distance fails to be adjustable
in accordance with the different users to incur operational
inconvenience.
SUMMARY OF THE INVENTION
[0007] The primary objective of the present invention is to provide
a push-up trainer, which is structurally preferably simple and
safe.
[0008] The secondary objective of the present invention is to
provide a push-up trainer, which is adjustable in accordance with
arm length of different users to reduce operational
inconvenience.
[0009] The foregoing objectives of the present invention are
attained by the push-up trainer, which is comprised of a base
having an underprop, a supporter movably mounted to the underprop
of the base, two pressing bars each having an end pivotably
connected to the supporter, and two upholding members respectively
detachably mounted to the pressing bars and each having a slidable
member contacting against the base.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
[0015] Referring to FIGS. 1-3, a push-up trainer 10 constructed
according to a preferred embodiment of the present invention is
comprised of a base 12, a supporter 14, two pressing bars 16, and
two upholding members 18.
[0016] The base 12 is normally placed on the floor, including a
circular chassis 20, an upright underprop 21 extending upwards from
a top center of the chassis 20, two elongated bottom struts 22
formed at two opposite sides of an peripheral edge of the chassis
20, and two lateral struts 24 horizontally perpendicularly formed
respectively at distal ends of the two bottom struts 22. Each of
the bottom struts 22 is provided with a guide slot 26 recessed
downwards from a top side thereof.
[0017] The supporter 14 includes a sleeve 28, a cushion 30 mounted
on a top side of the sleeve 28, and two pivoting portions 32
respectively mounted at two opposite sides of an outer peripheral
edge of a bottom side of the sleeve 28. The sleeve 28 is coaxially
fitted to the underprop 21 to be slidable along the underprop
21.
[0018] Each of the pressing bars 16 includes an elongated tubular
external bar 34 and an internal bar 36 fitted into the external bar
34. Each of the internal bars 36 has an end inserted into the
external bar 34 for slidable movement along a long axle of the
external bar 34, and the other end extending outwards and provided
with a handlebar 38. Each internal bar 36 has three positioning
holes 40 axially arranged thereon at an equal interval. The
external bar 34 has a pin 42 detachably inserted into one of the
positioning holes 40 for manipulating the distance between the
handlebar 38 and the external bar 34. The external bar 34 has the
other end pivotably mounted to the pivoting portion 32 of the
supporter 14 by a pivoting pin 44, such that each pressing bar 16
can be pivotable on the pivoting pin 44. Further, the external bar
34 has a plurality of through holes 46 running therethrough and
positioned relatively to the guide slot 26 of the base 12.
[0019] Each of the upholding members 18 is U-shaped, including a
slidable member 48, which is embodied as a pulley, rotatably
provided at_a bottom end thereof, and a locking member 50, which
can embodied as a pin or a bolt, detachably inserted through a top
end thereof into one of the through holes 46 of the pressing bar 16
to enable the upholding member 18 to be perpendicular to the
pressing bar 16. Each of the slidable members 48 extends towards
the base 12 to contact against the guide slot 26. When the locking
member 50 is fixedly inserted into different positioning holes 46,
an angle between each pressing bar 16 and the base 12 can be
adjustable.
[0020] From the above recitation, when the user does the push-up
exercise on the push-up trainer 10, the user has the hands
respectively hold the handlebars 38 and the chest lie against the
cushion 30. As shown in FIG. 4, the user's hands push the
handlebars 38 to move the handlebars 38 downwards, such that the
pressing bars 16 drive the sleeve 28 by leverage on a fulcrum, at
which the slidable member 48 contacts against the base 12, to move
upwards together with the cushion 30 along the underprop 21. In the
meantime, the user's body lies against the cushion for auxiliary
localization, thereby keeping the body in horizontally stationary
position while the user repeats the push-up exercise. In addition,
the sleeve 28 and the cushion 30 of the supporter 14 will not hurt
the user while they are moved upwards and downwards. When another
user of different arm length intends to operate the push-up trainer
10, the trainer 10 can be also applicable to this user by slidably
moving each of the internal bars 36 to a position that fits the
user's arm length relatively to the external bar 34 and fixing the
internal tube 36 to the external bar 34 by the pin 42. If the user
intends to strengthen the muscle of the arms with different
strength, one or both of the upholding members 18 can be fixed
respectively to different through holes 46 of one or both of the
pressing bars 16 by the locking members 50, such that there are
different angles formed between the base 12 and the pressing bar
16. Meanwhile, the user has to exert different strength to push the
pressing bars 16 to drive the sleeve 28 to move upwards, thereby
strengthening the muscle of the arms with different strength.
[0021] In conclusion, the present invention is structurally simple
and safe, and adjustable according to different users of different
arm length to reduce operational inconvenience.
