Description

[Detailed description of the device]

[0001]   The present invention is designed for an electric treadmill. Kerker arm structure, especially treadmill user Adapts to the natural curvature of both arms of the The present invention relates to a device for performing synchronous movement.

[0002]   Many existing commercially available electric treadmills have been Can swing back and forth, upright frame and base Two lockers attached to the base frame or railing Arms are provided. Furthermore, by adding motion resistance parts to the rocker arm, Can also train your arm strength when walking or jogging Growling. All of these are disclosed in, for example, US patent publications (for example, , Patent Documents 1 to 7).

[Problems to be solved by the device]

  However, the rocker arm structure disclosed in the above-mentioned U.S. Pat. Since it had a simple structure of connecting one axis, all its arcs were parabolic. It was This is clearly different from the natural movement of human movement, and therefore Both hands are unnatural when the user holds the rocker arm handle and jogs. It became a lot of exercise and lacked comfort.

[0005]   The present invention eliminates the above-mentioned drawbacks so that the movement of the movement is adjusted to match the expected movement of movement. A rocker door for an electric treadmill that responds to the natural arc of swing of both hands of the user. It is the first object to provide a mechanism for armchairs.   Another purpose of the present invention is to make full use of the function of the rocker arm. In addition, there is an electric train equipped with motion resistance parts, such as a weight and a small hydraulic cylinder device. A rocker arm for a dodmill is provided.

[0006]

[Embodiment of device]

  For a better understanding of the above and other objects of the invention, refer to the figures below The details will be described.

[0007]   First, referring to FIGS. 1 and 2, a first embodiment of the present invention is directed to an upright frame 12 and a floor frame. Of the electric treadmill 10 including the frame 14, the front leg support 16 and the rear leg support 18. Mounted on the frame. A console panel 20 is installed on the upright frame 12. Handrails 22 are attached to both sides thereof. The floor frame 14 has a continuous (Not shown) is a rotary walking surface (in-place rotation). It is attached and circulated. Two more rocker arms 30 stand upright It is attached to 12 and can be held by the user with both hands and rocked back and forth. Both of these Each of the rocker arms 30 has the same design corresponding to each other, and its structure is Swing arm with connecting rod 32 and handle 36 ) 34. The end of the connecting rod 32 is connected to the pivot 2 of the upright frame 12. 4 is pivotally connected to the upright frame 12 and the other end is a swinger. It is pivotally connected to the arm 34.

[0008]   The pivoting connection design of the connecting rod 32 and swing arm 34 allows It is possible to match the movement of the kicker arm 30 with the natural swinging degree of the user's arms. It is possible.   Also, by using the swing arm 34 and the handle 36, any place Apply at least one weight (not shown) to the exercise resistance to You can also train your muscular strength.   Furthermore, one end of the connecting rod is extended downward and connected to the corresponding pivots on both sides of the floor frame. You may.

[0009]   Further, as shown in FIGS. 3 and 4, in the second embodiment of the present invention, a rocker armor is used. A small hydraulic cylinder 40 is installed in a proper position of the frame 30 to further increase the motion resistance. ing. As can be seen from the figure, the connecting rod 32 is an extension strut. n post) 38, and the extension column 38 is a cylinder shaft of a hydraulic cylinder 40. 42 is connected. On the other hand, the end of the hydraulic cylinder 40 is suitable for the upright frame 12. It is connected so that it can be pivoted at a cut position. Therefore, the connecting rod 32 rotates on the pivot 24. When you do, exercise resistance is obtained.

[0010]   Of course, various changes and modifications in the above embodiment of the present invention may be covered by the scope of rights of the present invention. It is possible to carry out without deviating from.
