Description of the Invention: [Technical Field] The present invention provides an elliptical fitness machine with a stepper function, in particular, a front end of the stepping rod is provided with an adapter portion, and the bottom end of the support frame is matched with The side is provided with a symmetrical crossbar, the space type of the innovative structure. [Prior Art] According to the modern people's life, because of the progress of the times and the large increase in population, the space for activities that everyone in the city can allocate is quite limited, and because the modern people are busy, they rarely use outdoor space such as parks. , school sports ground, to achieve the opportunity to relax the bones. However, because indoor sports equipment occupies a small area and is not subject to time and weather restrictions, it is widely used by modern people, and the elliptical fitness machine with stepper function can best achieve sports. The effect, according to the development of the fitness machine, has attracted wide attention from the industry. Please refer to Figure 7 for the development of a partial decomposition diagram of the structural combination of the previous patent approval scheme No. 535606 "Improvement of stepper structure with stepping and elliptical cycle tracking movement" (such as attachment) The front end of the base includes a support rod, the upper portion of the support rod has a first pivot, the upper ends of the pair of swing arms are pivoted to the first pivot shaft, and the rear end of the base has a second pivot shaft, a pair The crankshaft is pivotally connected to the second pivot shaft; the front end of the pair of footrests is connected to the bottom end of the swing arm, and the rear end is pivoted to the crank, so that when the crank is operated in a ring shape, the pedaling rod can be driven synchronously; The support rod is provided with a symmetrical angle adjustment plate on the opposite side of the two pivot arms, and the angle adjustment plate is provided with a plurality of positioning holes at a position corresponding to the lower end portion thereof, and the 5 1285555 swing arm is located at the positioning hole. a movable knob is disposed at a relative position; a closed guide groove of a proper length is formed at a bottom end of the rear end of the pedal, and a slot is formed at an end of the guide groove; and the pulley is pivotally provided with a pulley Guide When the shaft of the movable knob is clamped in the positioning hole, the pedal lever can form an up and down stepping swing state; if the shaft of the adjustable knob is retracted from the positioning hole, and the pulley is When sliding to the limit of the slot in the end of the guide groove, the pedal lever can be used as an elliptical trajectory to circulate. _ The above structure uses the shaft of the adjustment activity knob to select the card to be placed or retracted from the positioning hole to change its motion path mode, although the foot pedal can have two kinds of fitness for stepping movement and elliptical rotary motion. The actor, however, has its shortcomings: It can be seen from the figure that the upper part of the support rod has a first pivot, the upper ends of the pair of swing arms are pivoted to the first pivot, and the front ends of the pair of pedals are connected to the swing arm At the bottom end, when the pedal is swung up and down, the tensile stress of the (A) swing arm is quite large, and the swing arm structure is designed to have a slender appearance, so the structure is over the years. During the operation time, the swing arm will cause fatigue deformation of the material, thereby reducing the service life of the stepper. Please refer to Figure 8 for the development of the structural combination of the structural combination of the "Oval Modification of the Elliptical Stepper" in the previous Patent Approved Announcement No. 563567 (such as the attachment). When stepping, there is no swing effect relative to the grip, but only an elliptical cycle exercise machine plus telescopic adjustment device. The stepping machine is provided with a rotating wheel at the rear end of the base, and a symmetrical crank is arranged on both sides of the rotating shaft 6 Γ 285555 to provide one end of the left and right two pedals, and the left and the right two The other end of the pedal is sleeved on the bottom of the sleeve, wherein the front end of the base is fixed with a telescopic bracket, and the upper end portion is provided with a control instrument panel device, and one side is fixedly fixed. And the two ends of the fixing frame pivotally extend a handrail bar, and the handrail bar protrudes from an extension of the bottom end of the fixing frame, and the extension is received in the sleeve; and the base is received in the sleeve; A symmetrical side support frame is arranged on each side of the telescopic support, and a movable link is pivoted on the opposite inner side of the support frame on both sides, and a shaft column is further extended on the bottom of the movable link on both sides. The two sleeves are respectively provided with one end of the left and right foot pedals to be pivoted respectively, so as to adjust the height of the handrail bar relative to the ground by adjusting the telescopic bracket. The foregoing structure is achieved by adjusting the height of the telescopic bracket to achieve a height that can change the height of the two symmetric handrails relative to the base, so that users who meet different heights can completely fit their own specifications, but the disadvantages are: The figure shows that one side of the base is provided with a fixing frame, and the base is provided with a symmetrical side support frame on both sides of the telescopic support, and the upper side of the support frame is pivoted on the opposite side of the inner side. The movable connecting rod, according to the manufacturer's previous patent approval, the (B) fixed frame, (C) side support frame, and (D) movable connecting rod and other relatively complicated structural design, although structural reinforcement can be generated. The role, but will lead to the expansion of the elliptical stepping machine volume, which in turn doubles the assembly space and manufacturing costs. In view of the shortcomings of the aforementioned conventional structure, the inventor of the present invention has been known for many years of experience in the manufacture of sports equipment and related products, and is well aware of the manufacturing methods and advantages and disadvantages of the fitness machine. After the trial, I finally invented the "Elliptical Fitness Machine with Stepper Function".
