Description

  The present invention relates to a structure of a step machine, and more particularly to a structure of a step machine in which a pedal can move up and down along a circumferential route.

  In the structure of a conventional step machine, the left and right pedals are provided on a frame in front of the step machine in front. When exercise is performed with the feet placed on the left and right pedals using this step machine, the left and right pedals move up and down repeatedly with the tip as the rotation axis. Although the structure of such a step machine has been adopted for a long time, there has been no significant change in its operation method, and some contractors have modified the above structure to add lateral movement to the step movement of the left and right pedals. However, the basic operation mode is still the step operation of the left and right pedals. However, in the highly competitive market, consumers' needs are fluctuating from day to day, which causes consumers to lose interest in goods and only gradually reduce their willingness to purchase.

  From another point of view, in the step operation using the left and right pedals, the bottom of the foot repeatedly steps, so that the heel is overloaded, and it is easy to cause movement injury such as pain and sprain.

  The interlocking mechanism 50 is provided on the first and second curve frames 21 and 22, and causes the interlocking action and an appropriate resistance force on the first and second curve frames 21 and 22. The interlocking mechanism 50 in this embodiment is located between the first chain 51 provided on the first curve frame 21, the second chain 52 provided on the second curve frame 22, and the main frame 10. The rotary shaft base 53 is installed, and the first and second conductive chains 541 and 542 are configured. The left chain and the right chain 531 and 532 are opposed to the first and second chains 51 and 52, respectively, at the left and right ends of the rotary shaft base 53, with the first conductive chain 541 serving as the first chain. The second transmission chain 542 is connected to the second chain 52 and the right chain 532 of the rotary shaft base 53. Here, as a supplementary explanation, the above-mentioned chain and the part of the conductive chain can be replaced with a wedge belt and a conductive belt (see the conductive belts 57 and 58 shown in FIG. 11).

  Based on the above-described structure, as shown in FIGS. 3, 4, and 7, the rotary shaft base 53 can be assembled on an elevating stage 60 in the middle of the main frame 10, and the elevating stage is plate-shaped. The elevating stage can be moved up and down along the vertical rail with the main frame 10. In the present embodiment, the two standing plates 15 provided at intervals in the central portion of the main frame 10 are for placing the plate-like lifting stage 60 between them. The vertical plate has a long guide rail 16 in the vertical direction, and the lifting stage 60 can restrict the lifting and lowering of the lifting stage 60 by attaching the convex column 61 to the long guide rail 16.
