New description: [New technical field] This creation has a kind of fitness equipment, especially a leg exerciser for the user to carry out leg or cardiopulmonary training in the room. [Prior Art], β in order to be able to exercise the leg muscles in the room ridge, or to perform cardio-aerobic training, let people simulate walking or running in the room - straight for fitness equipment . The most common of these are the treadmills'---the running age includes the wheel and the conveyor belt mounted on the pulley. The conveyor belt is mounted on the pulley block to form a flat mouth for the user to avoid. When the user runs on the conveyor belt, the conveyor belt is idling in place. ",,: The running action is more burdensome for the user's legs and knees, so the development of a variety of ladders and steps, ladders and steppers There are two pedals in the middle, which are used by the motor system to simulate the ladder or the action of both feet when walking. Such a machine imposes a small burden on the user's knee, but The machine is quite large and difficult to use for the general user in the home. A pair of this problem, such as Taiwan's new patent No. 414973, is not the oil-repeat stepper developed. This type of stepper relies on two The oil cylinder provides the elastic force of the pedaling and the elastic resilience of the job, and the volume of the traditional stepper is small. For the finer, the acceptance of f is two. However, the service life of the oil residual system is low and long. Time to step on the phenomenon of oil leakage or damage in the valley. In view of the above shortcomings, it is necessary to be smooth. [Embodiment] For the sake of further progress, the structure, use and characteristics of the creation are deeper and more detailed. _ knowledge and understanding The preferred embodiments of the present invention are described in detail below with reference to the drawings: Referring now to Figures 1D and 2, as shown in the drawings, in the preferred embodiment, the leg fitness machine of the present invention comprises at least one and the ground. The base 10 is placed in a close-fitting manner. In the embodiment, the base 1 is provided with a Η-shaped and horizontally disposed frame 12, and the towel end of the frame 12 extends upward to form a connecting end 13. The two sides of the two ends of the two ends of the two pedals 2 are respectively connected with a flexible structure 30. In this embodiment, the elastic structure 3 is provided. The first end of the leaf spring 31 is provided with a fixed end 32, and the fixed end 32 is elongated, and is substantially parallel to the direction of the pedal 20 and The pedal 20 is connected 'to increase the stability of the connection. And extends outwardly from the _ side of the above-mentioned fixed end 32 to form a suspension arm 33 which forms a downward curved shape of the concave surface 35, thereby The side where the suspension 33 is connected to the fixed end 32 is substantially the same as the fixed end The movable end 34 extending outwardly is flat on the ground surface u and is reciprocally slid along a predetermined path 5 平行 parallel to the ground U. And in this embodiment, In order to enhance the mechanical strength and the elastic restoring force of the suspension arm 33, a bottom surface of the suspension arm 33 is further provided with a spring I1 piece 36. The elastic spring piece 36 is provided to match the suspension arm 33. Line shape, the ship Qi in Shang Cong pay 33 _ end. However, it is only used for the side of the f brother, not the way to touch the boom 33 and the elastic brake 36; the foot on the Cong (four)% can be in the above _ end 32 A plurality of pieces of leaf springs or stretched elastic crystals are disposed between the blood moving ends 34. The sheet springs 31 are deformed when being stepped on (four), and elastic recovery ability when unstressed. The movable end 34 of the suspension arm 33 and the fixed end 32 are changed in accordance with the amount of perseverance, and the pedal 2 is oscillated up and down along with the surface treading. In addition, when the leaf spring 31 is subjected to the force of the force, the movable end 3 and the mountain 4 are reciprocally slid along the path parallel to the ground u, and further, in order to make the sliding movement of the movable end 34 smoother, further A sliding unit 4 is connected to the movable end 34 of the above 33. As shown in FIG. 3, in this embodiment, further, the suspension arm 33 and the movable end 34 are provided with a sliding unit 40 composed of a roller 41 and a path plate. The roller 41 is pivoted. Connected to the movable end 34, and the path plate 42 is disposed under the roller 41 and extends from the end of the base 1 沿着 along the sliding preset path 5〇 of the movable end 34. When the preset path 50 is slid, the roller 41 rolls the surface of the path plate 42 by the 'by design', not only reduces the frictional resistance between the movable end 34 and the ground 11, but also eliminates the unevenness of the ground. The phenomenon of slipping is not smooth. Please refer to Figure 4 and Figure 5, as shown in the figure, in order to further increase the effect of exercise and fitness, the front end of the pedal 2〇 is respectively connected with M433881 ' [main component symbol Description] 10...
