Description
BACKGROUND OF THE INVENTION
[0001] The present invention is related to an exerciser having a
main body for a user to lean thereon. A support section is disposed
under bottom face of the main body for contacting with the floor.
When the main body swings, the user's body will swing along with
the main body so that the exerciser can help the user in making
various types of exercises.
[0002] FIG. 7 shows a conventional situp board. An inclined board
body 62 is mounted on a frame body 61. Foam sponge rollers 63 are
disposed on the frame body 61 for a user's feet to hook and lean
thereon.
[0003] In use, the user's feet hook and lean on the foam sponge
rollers 63 and the user's body downward inclinedly lies on the
board body 62. By means of the strength of the waist, the user
lifts the upper half of the body to make situp exercise. When
exercising, the user lifts the upper half body all by his/her own
waist strength. Such movement is relatively laborious and not so
easy for most users, especially for beginners or those users
needing rehabilitation. Furthermore, when the user lifts his/her
body, the spine and cervical vertebra of the user are not supported
and will be bent and arched due to application force of the user.
This often incautiously results in injury. Also, the situp board
can be only used for situp exercise without other function.
[0004] FIG. 8 shows another exerciser having a base seat 71. A step
board 72 is disposed at one end of the base seat 71 and a seat 73
is positioned at the middle of the base seat 71. A swingable back
cushion 74 is pivotally disposed on the base seat 71 and a
resilient member 75 is connected between the back cushion 74 and
the base seat 71.
[0005] In use, both feet of the user step on the step board 72 with
his/her back leaning on the back cushion 74. When the stretching
force of both feet of the user exceeds the resilient force of the
resilient member 75, the back cushion 74 will swing backward to
stretch the user's body. Accordingly, the neck and back of the user
are properly supported and the exercise can be made to a greater
extent. However, this also is not suitable for those users needing
rehabilitation. Also, such exerciser can be used only in a specific
manner as aforesaid. Moreover, such exerciser has complicated
structure and is manufactured at higher cost and the possibility of
failure will be increased.
[0006] FIG. 9 shows a conventional situp exerciser having an arched
main body 8. A pillow 81 is disposed at one end of the main body 8
for a user's neck to lean thereon. The other end is provided with a
grip section 82 opposite to the pillow 81 for the user to hold.
[0007] In use, the user's neck leans on the pillow 81 and lies on
the floor. When both hands of the user exert a force to push the
grip section 82, the ring-shaped main body 8 will swing and the
pillow 81 will push the neck upward. Accordingly, the upper half
body of the user will be lifted to make situp exercise. When the
upper half body of the user is lifted, only the pillow 81 exerts a
pushing force on the user. In other words, the weak neck of the
user supports the weight of the upper half body of the user. This
is very likely to cause injury in exercise. Furthermore, when the
user lifts the upper half body, the spine and cervical vertebra of
the user are also bent and arched due to the application force.
This also tends to result in injury in case of improper force.
[0008] FIG. 10 shows a swinging exerciser. A shaft 92 is pivotally
disposed between two leg supports 91. The shaft 92 is connected
with the middle of a back cushion 93. A leg bracket 94 and a pillow
95 are respectively disposed at two ends of the back cushion
93.
[0009] The shaft 92 is connected with the middle of the back
cushion 93 so that the back cushion 93 has a form of titter in a
balanced state. In the case that one end suffers greater force, the
back cushion 93 will turn to the end. In other words, when the body
of the user exerts a force on one end of the back cushion 93, the
back cushion will swing and the user's body will swing along
therewith. Accordingly, the user can easily stretch his/her body
without costing much strength. However, the exercising effect will
be limited. Moreover, the back cushion 93 has a form of a titter so
that it tends to incautiously lose balance and turn. Also, the leg
supports 91 have a certain height so that the unbalanced back
cushion 93 will turn down to hit the floor by a considerable force.
This may hurt the user.
SUMMARY OF THE INVENTION
[0010] It is therefore a primary object of the present invention to
provide an exerciser including a main body having a support section
disposed under the bottom face of the main body for contacting with
the floor. The support section is positioned near one end of long
side of the main body to divide the main body into a long part and
a short part. In normal state, the main body contacts with the
floor in a stable state. When exercising, a user can stably lean
his/her body onto the main body and exert a force on the main body
by hands or legs to swing the main body. The user's body will swing
along with the main body so that the exerciser can help the user in
making various types of exercises.
[0011] It is a further object of the present invention to provide
the above exerciser in which the support section is arched so that
when the main body suffers a force and swings, the arched support
section rolls over the floor, whereby the main body simultaneously
swings and displaces to more effectively stretch the user's
body.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0026] Please refer to FIGS. 1 and 2. The exerciser of the present
invention includes a main body 1 which is a substantially
rectangular board for a user's body to lean thereon. The front and
rear sections of two sides of the main body 1 are respectively
provided with handles 14 for the user to hold. A support section 11
is disposed under the bottom face of the main body 1 for contacting
with the ground. The support section 11 is positioned near one end
of long side of the main body 1, whereby the main body 1 is divided
by the support section 11 into a long part 12 and a short part 13.
In this embodiment, the support section 11 is semicylindrical and
has an arched contact section in contact with the ground. When the
main body 1 suffers a force, the support section 11 can roll on the
floor and the main body 1 is swung along therewith.
[0027] The support section 11 is positioned near one end of long
side of the main body 1 so that in normal state, the long part 12
of the main body 1 and the support section 11 will at the same time
contact with the floor in a stable state. When a user lifts his/her
waist, the upper half of the user's body lies on the main body 1
with the head directed to the end at which the support section 11
is positioned. The user's legs step on the floor with the knees
bending. The head of the user is higher than the body as shown in
FIG. 3A. Both hands can embrace the chest or hold the handles 14.
At this time, the long part 12 and support section 11 of the main
body 1 lean on the floor in a stable state, permitting the user to
stably adjust the attitude. When exercising, the waist and legs of
the user at the same time exert a force to lift the lower half of
the user's body. At this time, the gravity center of the user
naturally moves to the upper half of the user's body and the head
and the short part 13 of the main body 1 suffers a depressing
force. With the short part 13 serving as the arm of applied force,
the depressing force will relatively create a lifting force onto
the long part 12 of the main body 1 as shown in FIG. 3B.
Accordingly, the main body 1 will help in lifting the user's body
and completing the waist-lifting exercise. Moreover, when the main
body 1 swings, the support section 11 rolls, whereby the main body
1 simultaneously displaces when swinging. Therefore, the user's
body can more effectively stretch.
[0028] When making push-up exercise, the user lies on the main body
1 with his/her face facing downward and his/her head directed to
the end distal from the support section 11. The user's legs step on
the floor with both hands straightened on the floor as shown in
FIG. 4A. At this time, only the support section 11 of the main body
1 leans on the floor. When exercising, both hands of the user bend,
making the upper half of the body depress the long part 12 of the
main body 1 and swing the main body 1. At this time, the body of
the user swings down along with the main body 1. When pushing up
the body, both hands of the user are straightened to lift the upper
half of the body. At this time, the gravity center of the user will
naturally move backward to create a depressing force onto the short
part 13 of the main body 1 and a lifting force onto the long part
12. This helps in lifting the upper half of the user's body and
completing push-up exercise as shown in FIG. 4B.
[0029] When making situp exercise, the upper half of the user's
body lies on the main body 1 with his/her head directed to the end
distal from the support section 11. The user's hip sits on the
short part 13 of the main body 1 with the legs stepping on the
floor and the knees bending as shown in FIG. 5A. At this time, the
gravity center of the user resides in the hip so that the short
part 13 and the support section 11 lean on the floor. Under such
circumstance, the main body 1 is still in a stable state. When
exercising, the user first lies down toward rear side to depress
the long part 12 of the main body 1 downward until the long part 12
and the support section 11 lean on the floor. At this time, the
gravity center of the user resides in the long part 12 so that the
main body 1 is again in a stable state. Thereafter, the user
utilizes the strength of the waist to again lift the upper half of
the body and again move the gravity center of the body to the short
part 13 of the main body 1. Accordingly, a depressing force is
exerted onto the short part 13 and the long part 12 is lifted. This
helps in restoring the upper half of the user's body back to a
position close to sitting attitude as shown in FIG. 5B. At this
time, the weight of the user depresses the short part 13 to restore
to the previous stable state.
[0030] In the above various types of exercises, the main body 1 is
always in a stable state without losing balance and making the user
get hurt. Moreover, the support section 11 serves as a fulcrum and
the short part 13 or long part 12 serves as the arm of applied
force. Therefore, the user only needs to lightly exert a force onto
the main body 1, whereby the main body 1 can resist against the
weight of the user's body and swing to achieve an exercising
effect. Therefore, the exerciser is quite suitable for a beginner
or a person needing rehabilitation. When the main body 1 suffers a
force, the support section 11 rolls over the floor and the main
body 1 is swung and displaced along therewith by a displacement L
as shown in FIG. 6. Accordingly, the user's body can more
effectively stretch to enhance the exercising effect.
[0031] According to the above arrangement, when exercising, a user
can stably lean his/her body onto the main body 1 and exert a force
on the main body 1 by hands or legs, whereby the main body 1 can
swing with the support section 11 in contact with the floor. At
this time, the user's body will synchronously swing with the main
body 1. Therefore, the present invention helps the user in making
various types of exercises. When the main body 1 suffers a force
and swings, the arched support section 11 rolls over the floor,
whereby the main body 1 simultaneously swings and displaces to more
effectively stretch the user's body.
[0032] The above embodiment is only used to illustrate the present
invention, not intended to limit the scope thereof. Many
modifications of the above embodiment can be made without departing
from the spirit of the present invention.
