Description

[0001] This application claims priority from Chinese Patent Application No. 2017 21567993.6 filed Nov. 22, 2017.

TECHNICAL FIELD

[0002] The present utility model refers to a type of fitness equipment, in particular to a type of dual function fitness equipment.

PRIOR ART

[0003] In the field of fitness equipment, stationary bikes are widely used due to their simple and easy to use structure. The existing stationary bikes are divided into vertical and with back support, among others. However, they usually have a sole function, that is, that the user sits in the seat, with his hands on the handlebars and his/her feet in the pedals, simulating the movement of riding a bicycle with a sole function or with some additional functions. For example, some stationary bikes have additional handles that may help to exercise the arms. However, their defect is the sameness of the basic frame of the stationary bike and the possibility of adding a few additional functions, without modifying the general function. Therefore, it is impossible to satisfy more needs.

Among them, the central body components include those that coordinate to comply with the stationary bike function: the base components, the handlebar components, the seat components, the pedals components and the resistance assembly. The mentioned shift mechanism is located between the base components and the handlebar components, and regulates and fixes the relative position between the handlebar and the base components to carry out the two different functions of the stationary bike. The shift mechanism includes: elliptical plate 1 fixed in the front tube of the base components, elliptical plate 2 fixed in the rear tube of the base components and elliptical plate 3 fixed in the handlebar bar of the handlebar components. The front tube, the rear tube and the handlebar bar are articulated with a pin to guarantee that the elliptical plates 1, 2 and 3 coaxially rotate over the articulation point. In the elliptical plate 1 there is a positioning hole 1; in the elliptical plate 2, the positioning hole 2, and the elliptical plate 3 has a strap spring pin, which pin coordinates with the positioning holes 1 and 2 respectively to fix the position and perform the function shift.

[0007] Furthermore, the bidirectional resistance adjustment mechanism is installed in the upper part of the handlebar bar; and includes the central body of the adjustment mechanism, which adjustment device coordinates with the resistance assembly to regulate the resistance. The adjustment device has a coaxial bar that protrudes the two ends of the main body. Each end of said bar has a knob. Turning each of them can activate the rotation of the coaxial bar and the coordination between the adjustment device and the resistance assembly to reach the purpose of regulating the resistance.

[0008] Furthermore, the described screen adjustment mechanism is installed in the cross bar of the handlebar components, and includes: the central body of the panel that rotates over the rotation axis and has a position stop. The rotation axis has a protruding point to limit the position. The position stop and the protruding point to limit the position are coordinated to guarantee that the central body of the panel can only rotate 180.degree. over the rotation axis. On the other hand, there is a fixation slot in the central body of the panel and a fixation point in the rotation axis. Both are coordinated to carry out the temporary fixation of the central body of the panel.

[0009] When adopting the above mentioned technical solution, this utility model works as an ordinary horizontal stationary bike in its normal operation and, through the shift mechanism, the user can rotate it and fix the handlebar mechanisms to fix the angle and transform it into a vertical stationary bike. The user exercises from the other direction placing the feet in the pedals and the hands in the handles. In this manner, the shift is performed free of the two functions, with a simple and easy to regulate structure.

[0010] On the other hand, in order to coordinate with the bidirectional use function, this utility model also includes an adjustment mechanism of bidirectional resistance, easy to use, that is installed in the upper part of the handlebar bar to guarantee that the user can regulate the resistance in both directions. Furthermore, in the cross bar of the components of the handlebar, the screen adjustment mechanisms is installed to guarantee that the user, when exercising sitting or vertically, can rotate the panel at any time to perform the adjustment of 180.degree. and read the data in the screen in both sides.
