Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a movable kneeling pad
assembly for an abdominal exercise device, especially to a movable
kneeling pad assembly that is helpful in enhancing abdominal
exercise intensity.
[0003] 2. Description of the Prior Art(s)
[0004] An abdominal exercise device is used to train abdominal
muscles of a user. A conventional abdominal exercise device
comprises a kneeling pad and a roller assembly. The kneeling pad is
immovably disposed on a plane and has two kneeling recesses
separately formed in an upper surface of the kneeling pad. The
roller assembly has a wheel and a handle transversely mounted
through the wheel. The roller assembly is movable relative to the
kneeling pad by rotation of the wheel. In use, the user kneels on
the kneeling pad with his knees placed in the kneeling recesses and
his hands holding the handle to repeatedly move the roller assembly
forward and backward, thereby allowing the user to train the
abdominal muscles.
[0005] However, since the kneeling pad is immovably disposed on the
plane, when the user repeatedly moves the roller assembly forward
and backward, the user does not have to put forth abdominal
strength to sustain his lower body. The abdominal strength of the
user is only put forth to allow an upper body of the user to
perform movement. Hence, the conventional abdominal exercise device
is unable to train the abdominal muscles of the user effectively
and efficiently. Exercise intensity when using the conventional
abdominal exercise device is not enough for professional workout
exercisers.
[0006] To overcome the shortcomings, the present invention provides
a movable kneeling pad assembly for an abdominal exercise device to
mitigate or obviate the aforementioned problems.
SUMMARY OF THE INVENTION
[0007] The main objective of the present invention is to provide a
movable kneeling pad assembly for an abdominal exercise device. The
movable kneeling pad assembly has a main pad and a wheel seat. The
main pad has at least one kneeling recess formed in an upper
surface of the main pad. The wheel seat is mounted on a lower
surface of the main pad and has multiple wheels protruding from the
lower surface of the main pad.
[0008] The kneeling pad assembly provides a comfortable support for
a user's knees. As the kneeling pad assembly is movable by rotation
of the wheels, the user has to put forth high abdominal strength in
order to simultaneously perform movements of his upper body and his
lower body. Therefore, abdominal muscles of the user can be trained
effectively and efficiently, and exercise intensity when using the
abdominal exercise device is high enough for professional workout
exercisers.
[0009] Other objectives, advantages and novel features of the
invention will become more apparent from the following detailed
description when taken in conjunction with the accompanying
drawings.

of foam material, and has an upper surface, a lower surface, two
opposite sides, at least one kneeling recess 11, a mounting recess
12, an inner bottom, multiple connecting protrusions 123, multiple
positioning recesses 14, and four wheel recesses 13.
[0021] The at least one kneeling recess 11 is formed in the upper
surface of the main pad 10 and are ergonomically designed to
correspond to contours of the human knees, thereby providing a
comfortable support for a user's knees. Specifically, the main pad
10 has two kneeling recesses 11 spaced apart.
[0022] The mounting recess 12 is formed in the lower surface of the
main pad 10, is H-shaped, and has a transverse portion 121 and two
longitudinal portions 122. The transverse portion 121 is disposed
on the lower surface of the main pad 10 and has two ends
respectively extending toward the two opposite sides of the main

adjacent to the two opposite sides of the main pad 10, are parallel
to each other, are respectively connected to the ends of the
transverse portion 121, and communicate with the transverse portion
121. Each longitudinal portion 122 has two ends. The inner bottom
of the main pad 10 is defined in the mounting recess 12.
[0023] The connecting protrusions 123 are separately formed on and
protrude from the inner bottom of the main pad 10. In the first
preferred embodiment, the main pad 10 has two connecting
protrusions 123 respectively disposed at the ends of the transverse
portion 121 of the mounting recess 12.
[0024] The positioning recesses 14 are separately formed in the
inner bottom of the main pad 10. In the first preferred embodiment,
the main pad 10 has two positioning recesses 14 respectively
disposed on the longitudinal portions 122 of the mounting recess
12.
[0025] The wheel recesses 13 are formed in the inner bottom of the
main pad 10 and are respectively disposed at the ends of the
longitudinal portions 122 of the mounting recess 12. In other
words, the wheel recesses 13 are respectively disposed at four
corners of the inner bottom of the main pad 10.
[0026] The wheel seat 20 is mounted on the lower surface of the
main pad 10 and has a bracket 21 and four wheels 22.
[0027] The bracket 21 is H-shaped to fit the H-shaped mounting
recess 12, is detachably mounted in the mounting recess 12 of the
main pad 10, and has a first surface, a second surface, a
transverse panel 211, two longitudinal panels 212, multiple
connecting holes 213, multiple positioning holes 215, and four
pairs of pivot supports 214. The second surface of the bracket 21
is opposite to the first surface of the bracket 21.
[0028] The transverse panel 211 is mounted in the transverse
portion 121 of the mounting recess 12 and has two ends. The
longitudinal panels 212 are respectively connected to the ends of
the transverse panel 211, are parallel to each other, and are
respectively mounted in the longitudinal portions 122 of the
mounting recess 12. Each longitudinal panel 212 has two ends.
[0029] The connecting holes 213 are separately formed through the
bracket 21, and respectively correspond to the connecting
protrusions 123 of the main pad 10 for the connecting protrusions
123 to engage the connecting holes 213, such that the wheel seat 20
is detachably mounted on the lower surface of the main pad 10. In
the first preferred embodiment, the bracket 21 has two connecting
holes 213 respectively disposed at the ends of the transverse panel
211 of the bracket 21.
[0030] The positioning holes 215 are separately formed through the
bracket 21 and respectively correspond in position to the
positioning recesses 14 of the main pad 10. In the first preferred
embodiment, the bracket 21 has two positioning holes 215
respectively disposed on the longitudinal panels 212 of the bracket
21.
[0031] The pairs of the pivot supports 214 are formed on and
protrude from the first surface of the bracket 21, are respectively
disposed at the ends of the longitudinal panels 212, and are
selectively stored respectively in the wheel recesses 13 of the
main pad 10. In other words, the pairs of the pivot supports 214
are respectively formed on and protrude from four corners of the
first surface of the bracket 21.
[0032] The wheels 22 are pivotally mounted on the first surface of
the bracket 21, are respectively mounted pivotally on the pairs of
the pivot supports 214 and are selectively stored in the wheel
recesses 13 of the main pad 10 along with the pairs of the pivot
supports 214. In other words, the wheels 22 are respectively
mounted pivotally on the four corners of the first surface of the
bracket 21.
[0033] The holders 40 are respectively mounted through the
positioning holes 215 of the bracket 21 and respectively protrude
into the positioning recesses 14 of the main pad 10. Each holder 40
has a peripheral side surface and a flange 41. The flange 41 is
formed around the peripheral side surface of the holder 40 and
abuts the bracket 21, such that the bracket 21 is held between the
main pad 10 and the flanges 41 of the holders 40.
[0034] With reference to FIGS. 8 and 9, in a second preferred
embodiment of a movable kneeling pad assembly for an abdominal
exercise device in accordance with the present invention, the main
pad 10A is formed by combination of two half-pads 101A. The two
half-pads 101A are spaced apart. Each half-pad 101A has an upper
surface and a lower surface. The main pad 10A has two kneeling
recesses 11A respectively formed in the upper surfaces of the
half-pads 101A. The longitudinal potions 122A of the mounting
recess 12A of the main pad 10A are respectively formed in the lower
surfaces of the half-pads 101A. The longitudinal panels 212A of the
bracket 21A are respectively mounted in the longitudinal portions
122A of the mounting recess 12A of the main pad 10A. The transverse
panel 211A of the bracket 21A extends between the two half-pads
101A.
[0035] With further reference to FIG. 3, when the wheel seat 20 is
mounted in the mounting recess 12 of the main pad 10 with the
second surface of the bracket 21 corresponding to the inner bottom
of the main pad 10, the wheels 22 protrude from the lower surface
of the main pad 10, such that the kneeling pad assembly is
movable.
[0036] With further reference to FIG. 4, the movable kneeling pad
assembly is used in cooperation with a roller assembly 30. The user
kneels on the main pad 10 with his knees placed in the kneeling
recesses 11 and his hands holding a handle 31 of the roller
assembly 30. At first, the user breathes in, moves the roller
assembly 30 backward toward the kneeling pad assembly, hunches his
back to an extreme extent, and tenses his hips to make his thighs
perpendicular to the ground. With further reference to FIG. 5, then
the user breathes out, moves the roller assembly 30 forward away
from the kneeling pad assembly, and stretches his body. Afterwards,
the user moves the roller assembly 30 backward toward the kneeling
pad assembly and kneels on the kneeling pad assembly again. With
repeating movements as described, abdominal muscles of the user can
be trained. Furthermore, as the kneeling pad assembly is movable by
rotation of the wheels 22, the user has to put forth high abdominal
strength in order to simultaneously perform movements of his upper
body and his lower body. Therefore, the abdominal muscles of the
user can be trained effectively and efficiently with intensity
strong enough for professional workout exercisers.
[0037] With further reference to FIGS. 6 and 7, when the wheel seat
20 is up-down reversed and is mounted in the mounting recess 12 of
the main pad 10 with the first surface of the bracket 21
corresponding to the inner bottom of the main pad 10, the
connecting protrusions 123 of the main pad 10 are respectively
mounted through the connecting holes 213 of the bracket 21, and the
holders 40 are respectively mounted in the positioning holes 215 of
the bracket 21 and the positioning recesses 14 of the main pad 10
with the flanges 41 of the holders 40 abutting the bracket 21.
Accordingly, the wheels 22 and the pairs of the pivot supports 214
are respectively stored in the wheel recesses 13 of the main pad
10. As shown in FIG. 7, since the wheels 22 are stored in the wheel
recesses 13 of the main pad 10 rather than protrude from the lower
surface of the main pad 10, a volume of the kneeling pad assembly
can be reduced for the convenience of packing and storage.
Moreover, as the kneeling pad cannot be moved with the rotation of
the wheels 22 in up-down reversal, the abdominal exercise device
with the immovable kneeling pad is suitable for amateur exercisers
with lower workout intensity.
[0038] 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.
