BACKGROUND OF THE INVENTION
Field of the Invention
[0001] The present invention relates to an exercise device, especially to an exercise device
for alternating movement of arms and legs in which users' arms and legs are driven
to move in an alternating manner.
Description of Related Art
[0002] A plurality of exercise devices, equipment, or machines are available now for stretching
and training body's muscle groups such as limb muscles. These devices include a chair/seat
and a leg support extended from the chair/seat. While user's legs are put on the leg
support, the legs can be pressed or extended through the actuated device. These devices
are mainly used for training and strengthening user's limb muscles or leg muscles.
[0003] However, these devices also apply intense pressure to user's arms and ankles. Refer
to
US Pat. No.5,277,681, an exercise machine to stretch one or more muscle groups or joints of a body part
is revealed. The exercise machine provides trunk rotation stretch and plantar flexor
stretch. There are at least one foot engagement members pivotable about a horizontal
axis one the machine frame and this axis corresponding generally to the location of
the ankle joint of the user. Thus, certain pressure is put on the ankles. In most
of exercise machines already disclosed and available now, a stronger pull is required
compared with a push force, or certain pressure is applied to the ankle. The design
of the exercise machine is too complicated and the exercise intensity is too much.
[0004] Thus, there is room for improvement and there is a need to provide an exercise device
with novel design.
SUMMARY OF THE INVENTION
[0005] Therefore it is a primary object of the present invention to provide an exercise
device for alternating movement of arms and legs which is not only having simple structure
and easy to operate, but also safe to use, without causing exercise-induced injuries
easily. For users who need rehabilitation exercise, the present exercise device provides
low intensity yet effective exercise.
[0006] It is another object of the present invention to provide an exercise device for alternating
movement of arms and legs in which users use their arms/or legs moving actively in
an alternating manner to drive their legs/or arms and abdomens to have passive movement,
moved up and down repetitively.
[0007] In order to achieve the above objects, an exercise device for alternating movement
of arms and legs according to the present invention includes a base, a hand driving
member, a connection rod, a set of linkage composed of a first rod and a second rod,
and a leg driving member.
[0008] The base consists of a first portion, an extended second portion, and an extended
third portion.
[0009] The hand driving member is pivotally disposed on the first portion of the base.
[0010] The leg driving member is pivotally mounted to the third portion c of the base.
[0011] One end of the hand driving member is able to be rotated at the base and one end
of the leg driving member is also able to be rotated at the base.
[0012] One end of the connection rod is pivotally connected to the hand driving member while
the other end thereof is pivotally connected to the first rod.
[0013] The set of linkage includes at least one first rod and at least one second rod. One
end of the first rod is pivotally connected to the connection rod and a middle portion
of the first rod is pivotally connected to the base while the other end of the first
rod is pivotally connected to one end of the second rod and the other end of the second
rod is pivotally connected to the leg driving member. This set of linkage enables
the hand driving member and the leg driving member to link and move with each other
for lifting up or pressing down arms and legs and stretching. The stretch of arms
and legs also applies pressure to the abdomen to exercise the abdomen.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0015] Refer to Fig. 1 and Fig. 2, an exercise machine according to the present invention
includes a base 1, a hand driving member 2, a connection rod 3, a linkage A composed
of a first rod 4 and a second rod 5, and a leg driving member 6.
[0016] The base 1 consists of a first portion a, an extended second portion b, an extended
third portion c, and an extended fourth portion d.
[0017] The hand driving member 2 is formed by a first end 2a, an extended second end 2b
pivotally disposed on the first portion a of the base 1, and an extended third end
2c.
[0018] The connection rod 3 is composed of an upper end 3a pivotally connected to the third
end 2c of the hand driving member 2, and an extended lower end 3b.
[0019] The linkage A includes at least one first rod 4 and at least one second rod 5 composed
of a first pivot end 5a and an extended second pivot end 5b. The first rod 4 is formed
by a front portion 4a pivotally connected to the lower end 3b of the connection rod
3, an extended middle portion 4b pivotally connected to the second portion b of the
base 1, and an extended rear portion 4c pivotally connected to the first pivot end
5a of the second rod 5. In this embodiment, the first rod 4 and the second rod 5 are
arranged in parallel to each other and used in combination with each other as a set.
[0020] The leg driving member 6 is provided with a third pivot end 6a, an extended fourth
pivot end 6b, and an extended adjustment end 6c. The third pivot end 6a is pivotally
disposed on the second pivot end 5b of the second rod 5 while fourth pivot end 6b
is pivotally mounted to the third portion c of the base 1. The adjustment end 6c is
provided with a plurality of adjustment holes 62 spaced apart from one another vertically,
a stepped portion 61 with an assembly hole, and a fixing member 63. The stepped portion
61 can be aligned and assembled with one of the adjustment holes 62 selectively and
then the fixing member 63 is inserted through the adjustment hole 62 and the assembly
hole of the stepped portion 61 for fixing. Thereby the position of the stepped portion
61 at the adjustment end 6c of the leg driving member 6 such as the upper position
or the lower position can be adjusted and the length of the leg driving member 6 is
also adjusted for users to adjust a driving force they apply during the performance
of the exercise. For example, the user needs to apply a larger driving force when
the stepped portion 61 is at the upper position of the adjustment end 6c. While the
stepped portion 61 is at the lower position of the adjustment end 6c, the user only
needs to apply a smaller driving force.
[0021] Moreover, the hand driving member 2 is able to be rotated at the first portion a
of the base 1 and the leg driving member 6 is able to be rotated at the third portion
c of the base 1.
[0022] The hand driving member 2 and the e leg driving member 6 are moved along with each
other by means of a set of the linkage A so that user's arms and legs can elevate
up and down for stretch. The user's arms and legs can also apply pressure to the abdomen
to perform abdominal exercises during stretching of the arms and legs.
[0023] The first end 2a of the hand driving member 2 is provided with a handle 21 while
the third end 2c of the hand driving member 2 is pivotally connected to the upper
end 3a of the connection rod 3 by a detachable pivot element 22. The pivot element
22 can be removed from the hand driving member 2 and the connection rod 3 so that
the hand driving member 2 can be folded downward for convenient storage and reduced
packaging volume.
[0024] The second portion b of the base 1 is connected with a stand 12 which is mounted
to the base 1 by a detachable positioning part 13. Once the positioning part 13 is
removed from the second portion b of the base 1, the stand 12 can be folded inward
for convenient storage and reduced packaging volume.
[0025] The fourth portion d is provided with a support base.
[0026] As shown in Fig. 3, while in use, a user sits on a chair with his/her hands on the
hand driving member 2 and legs on the stepped portion 61 of the leg driving member
6. Refer to Fig. 4, the user puts his/her hands on the handle 21 for pressing the
hand driving member 2 downward actively through the handle 21 and the connection rod
3 is moved upward along with the movement of the hand driving member 2. Then the first
rod 4 is driven to rotate pivotally and going up left to right so that the second
rod 5 is further pressed by the first rod 4 to move downward. Thus, one end of the
leg driving member 6 which is not connected to the second rod 5 is lifted. As shown
in Fig. 4, the user's legs are bent in knees and lifted up passively to press the
abdomen. Then the legs are pressed against the abdomen. Alternately, the user uses
their legs to press the stepped portion 61 down actively so that the second rod 5,
the first rod 4, and the connection rod 3 are driven to move in turn. Then the connection
rod 3 is pulled downward and the third end 2c of the hand driving member 2 is also
moved downward along with the connection rod 3 so that the hand driving member 2 is
going down left to right and the user's hands on the handle 21 are lifted up and returned
to the position showing in Fig. 3. Therefore, the user's arms are pulled up and stretched
passively. The user is easy to get into fitness by alternating active exercises and
passive exercises repetitively.
[0027] Furthermore, another embodiment is disclosed in Fig. 5. The linkage A is arranged
at the second portion b of the base 1 and is composed of a first drive wheel 4' and
a second drive wheel 5'. One end of a circular side surface of the first drive wheel
4' is pivotally connected to the connection rod 3 and one end of a circular side surface
of the circumference of the second drive wheel 5' is pivotally connected to the leg
driving member 6 while the first drive wheel 4' drives the second drive wheel 5' to
rotate. Also refer to Fig. 6, while an user sits on a chair with his/her hands holding
the handle 21 and legs placed on the stepped portion 61, the user presses the handle
21 down so that the hand driving member 2 drives the connection rod 3 to move upward.
Now the first drive wheel 4' is driven to rotate toward one direction by the connection
rod 3 and the second drive wheel 5' is further driven to rotate toward one direction
correspondingly. Thus, the leg driving member 6 is pulled upward and the user's legs
are bent and lifted up. Alternately, the user presses the stepped portion 61 down
actively by their legs so that the second drive wheel 5' is also moved to drive the
first drive wheel 4' rotating in the opposite direction. Then the connection rod 3
is moved along with the first drive wheel 4' and pulled downward. Thus, the third
end 2c of the hand driving member 2 is also moved downward along with the connection
rod 3 so that the hand driving member 2 is going down left to right and the user's
hands on the handle 21 are lifted up and returned to the position showing in Fig.
5. Therefore, the user's arms are pulled up and stretched passively. The user is easy
to get the body in shape by alternating active exercises and passive exercises repetitively.
