ABSTRACT:
FIELD OF THE INVENTION
The present invention relates generally to an exercise device, and more particularly to an embracing mechanism of the exercise device.
BACKGROUND OF THE INVENTION
As shown in
FIG. 1
, a prior art exercise device
1
comprises a frame body
2
, an embracing mechanism
3
mounted on the frame body
2
, a weight set
4
, a plurality of pulleys
5
mounted on the frame body
2
, and a plurality of ropes
6
running through the pulleys
5
such that both ends of the ropes
6
are connected with the embracing mechanism
3
and the weight set
4
. When a person uses the exercise device
1
to do the embracing exercise, the person must overcome the reaction force which is provided by the weight set
4
via the ropes
6
.
The embracing mechanism
3
has two suspension arms
7
which are fastened pivotally with the frame body
2
such that the two suspension arms
7
are separated at an interval to facilitate the embracing of the suspension arms
7
with both elbows, or the holding of the suspension arms
7
with both hands of the person using the exercise device
1
. The suspension arms
7
are fixed such that the distance between the two suspension arms
7
can not be adjusted in accordance with the body size of a person using the exercise device
1
.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide an exercise device with an embracing mechanism having two suspension arms which are adjustable in distance between the two suspension arms.
In keeping with the principle of the present invention, the foregoing objective of the present invention is attained by an exercise device comprising a frame body, a plurality of pulleys mounted on the frame body, a weight set, a plurality of ropes which run on the pulleys such that the ropes are fastened at one end thereof with the weight set, and an embracing mechanism mounted on the frame body and composed of two pivoting members, two suspension arms, and two driven members. The two pivoting members are fastened pivotally with the frame body. The two suspension arms are fastened pivotally with the two pivoting members. The two driven members are coaxially pivoted between the pivoting members and the frame body such that the two driven members are exerted on by the action force of the weight set via the ropes. The two suspension arms can be actuated by an external force to turn in a vertical surface such that the two suspension arms can be stopped at an appropriate position to enable the interval between the two suspension arms to adapt to the user's requirement.
