Description

sports equipment

technical field

The utility model relates to a sports device, in particular to a stepper.

Background technique

A stepper is a piece of exercise equipment that increases your heart rate, burns calories, and improves heart muscle endurance.

In the traditional stepper design, the user stands on two pedals with predetermined resistance, and the two pedals are lifted alternately by applying force with both feet. The movement of the steps is like continuously going up the stairs, thereby exercising the muscles of the legs and buttocks. Compared with treadmills, steppers have less impact on the legs, but care must be taken when using them to avoid knee injuries.

1A and 1B show the structures of two traditional steppers. FIG. 1C shows the movement trajectory of the pedals in FIG. 1A , and FIG. 1D shows the movement trajectory of the pedals in FIG. 1B . Fig. 1A is a structure of fixed-axis single-link, and Fig. 1B is a structure of fixed-axis double-link. The pedal 20 is fixed to the connecting rod 22, and one end of the connecting rod 22 is connected to the shaft 21, so that the motion track P of the pedal is in an outer arc shape, and its center points away from the user. This kind of motion track is not ergonomic and cannot simulate the actual stepping, Stepping, or climbing.

US Patent No. US20120077645 discloses a stepper, wherein a crankarm (crankarm) exerts force on a swing tube (linking units), so that a connecting rod (pedallink) connected to the swing tube moves forward and backward. The connecting rod has a rollable anti-friction member pivotally connected with a pedal. When the connecting rod moves forward, the pedal is driven by the roller to move obliquely forward and upward along the climbing rod (ramprod). In the above-mentioned structure, the thrust of the pedals rising is insufficient, and it is difficult to simulate actual stepping, striding, or mountain climbing.

About the stepper of existing known technology, also can refer to Chinese Taiwan patent certificate No. TWI458519, be entitled " adjustable stepper ", and Chinese Taiwan patent certificate No. TWI442955, be entitled patent applications such as " stepper ". These two patents both disclose a stepper with a fixed-axis double-link structure. Among them, the patent certificate number TWI458519 discloses that the crank is connected with the adjusting rod group, and the distance between the two pedals is adjusted by changing the angle of the crank. Patent Publication No. TWI442955 discloses a driving wheel set, the user drives the driving wheel set through a connecting rod set, and the driving wheel set drives a flywheel set.
