The present invention relates to treading exercise machines, and particularly to a treading exercise machine having twisting operation function, wherein the legs, bottom and waist of users are trained by using the present invention. Furthermore, the present invention has a compact size and a simple structure without any handle so as to train the equilibrium feeling of the users.
Treading exercise machines are now widely used because of the small volume of the machine and having a high efficiency in training.
However the prior art treading exercise machine has only the upward and downward movements. Only the muscles of thighs are trained. However most of fats are accumulated on the bottoms and waists. Thus the effect of treading exercise machine is finite.
In one improvement structure, a rectangular frame is installed with a supporting handle at a front end thereof and a Y shape frame at a rear end thereof. The manifolds of the Y shape frame are installed with sleeves. Each sleeve is extended with a treadle. The outermost end of the manifold is installed with a V shape rod for enhancing the treading force upon the treadle. A pressure tube is installed between a front end of the treadle and the V shape rod. A pressure rod is installed between a rear end of the treadle and the rectangular frame. Thereby the treading operation is performed in the upward and downward directions.
The prior art has the following disadvantages. The structure is too complicate to have a small volume. Thereby the cost is high and it is difficult in transfer process. Furthermore, the machine only moves upwards and downwards so that the muscles of the bottoms and waists are not trained in the exercise.
Accordingly, the primary object of the present invention is to provide a treading exercise machine having twisting operation function, wherein the legs, bottom and waist are trained by using the present invention. Furthermore, the present invention has a compact size and a simple structure without any handle so as to train the equilibrium feeling of the users.
To achieve above objects, the present invention provides a treading exercise machine having twisting operation function which comprises a body having a seat; a supporting tube extending upwards from the seat; a pivotal unit being pivotally installed at two sides of the supporting tube; the pivotal unit having two inclined rods at two sides of the supporting tube; each inclined rod being obliquely upwards so that the two inclined rods being formed with a V shape; two pressure cylinders each being between one of the two treadles and the seat 10; and a linking unit installed between the pivotal unit and the supporting tube for driving the two treadles; the linking unit having pulley and a rope for driving the pivotal unit so as to drive the two treadles.
The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing.
In order that those skilled in the art can further understand the present invention, a description will be described in the following in details. However, these descriptions and the appended drawings are only used to cause those skilled in the art to understand the objects, features, and characteristics of the present invention, but not to be used to confine the scope and spirit of the present invention defined in the appended claims.
With reference to
A body 1 is included.
A seat 10 includes a front base 11 and a cambered rear base 12. A main shaft 13 serves to connect the front base 11 and the rear base 12. A supporting tube 14 is installed on the front base 11 for supporting the body 1.
A pivotal unit 20 is pivotally installed at two sides of the supporting tube 14. The pivotal unit 20 has two inclined rods 21 at two sides of the supporting tube 14. Each inclined rod 21 is obliquely upwards so that the two inclined rods 21 are formed as a V shape. Each inclined rod 21 is installed with a sub-tube 22, a washer 23, a lower ring 24, a pivotal tube 25, an upper ring 26, a C ring 27 and a cap 28 sequentially so that the inclined rod 21 may swing upwards.
A linking unit 30 is formed by a pulley 31, a rope 32, a U shape supporting frame 33, and connecting rods 34. One end of the supporting frame 33 is firmly secured to a rear end of the supporting tube 14 by an adjusting screw screwing through the supporting tube 14 and another end thereof is pivotally installed with the pulley 31 so that the rope 32 can be installed on the pulley 31 along a sliding channel of the pulley 31. Two ends of the rope 32 are pivotally installed to the connecting rods 34. Each connecting rod 34 is pivotally installed to the pivotal tube 25. When the linking unit 30 rotates, the pivotal unit 20 will rotate.
Two treadles 40 are included. Each treadle 40 is installed to a respective one pivotal tube 25 of the pivotal unit 20 for being treaded by users. A front end of the treadle 40 is installed with a stopper 41 for preventing the faults in treading so as to increase the security in operation.
Two pressure cylinders 50 are installed at two sides of the main shaft 13. One end of each pressure cylinder 50 is connected to one end of the main shaft 13 by a universal connector and another end thereof is installed to a respect one of the treadle 40 for increasing the damping coefficient of the treading exercise machine so that the user will make more effort in treading.
A counting unit 60 is installed at a top end of the supporting tube 14. An upper side of the counting unit 60 is installed with a display 61 for displaying the counting result. A lower side of the display 61 is installed with a control portion 62 for controlling the counting process, such as reset operation.
With reference to
The pivotal unit 20 on the supporting tube 14 makes the treading exercise machine to swing obliquely. The structure of the supporting tube 14 and pivotal unit 20 are like a Y shape so that the treading exercise machine also rotates along the inclined rod 21 so that the swinging and rotation operations can be performed by the present invention. With reference to
Furthermore, no handle is used in the present invention so as to train the equilibrium feeling of the user in the upper, lower, left and right sides.
The present invention is thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the present invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
