Description

Treadmills

Technical field

The present invention is with regard to a kind of telecontrol equipment, particularly a kind of treadmills.

Background technology

Treadmills is a kind of sports equipment, can lift HR Heart Rate, burn calories, and lift the heart Flesh endurance.

In traditional treadmills design, user stands on predetermined resistance two pedals, and both feet are applied Power makes two pedals alternately be lifted, the action of step as continuously along stair up, leg exercising whereby With the muscle of buttocks.Compared to treadmill, treadmills is less for the impulsive force of leg, but using upper It has to be noticed that to avoid knee injury.

Figure 1A and Fig. 1 C are the structure of two kinds of traditional treadmills, and Figure 1B is the pedal travel track of Figure 1A, Pedal travel tracks of Fig. 1 D for Fig. 1 C.Figure 1A is a kind of structure of dead axle list connecting rod, and Figure 1B is one Plant the structure of dead axle double link.Pedal 20 is fixed on connecting rod 22, and one end connecting shaft 21 of connecting rod 22, So that the movement locus P of pedal is in outer camber, its center is pointed to away from user, and this kind of movement locus is not Symbol ergonomics, it is impossible to which emulation is actual to mark time, strides, or mountaineering.

United States Patent (USP) US20120077645 discloses a kind of treadmills, wherein crank (crank arm) force Give swing pipe (linking units) so that the connecting rod (pedal link) being connected with swing pipe is moved forward and backward. Connecting rod has roller (rollable anti-friction member) and pedal (pedal) pivot joint.When Connecting rod displacement forward, drives pedal by roller, moves along the bar that climbs (ramp rod) toward oblique front upper place It is dynamic.In said structure, the thrust that pedal rises is not enough, it is difficult to which simulation is actual to mark time, strides, Or mountaineering.

Additionally, the treadmills of existing known techniques, it is impossible to for different users, adjust stride Size and angle.

Additionally, the treadmills of existing known techniques, pedal slides along the track for limiting, and can produce different Sound.

With regard to the treadmills of existing known techniques, reference may also be made to TaiWan, China letters patent book number is TWI458519, entitled " adjustable running exerciser ", and TaiWan, China letters patent book number are The patent application cases such as TWI442955, entitled " treadmills ".

In view of above-mentioned existing treadmills, the present inventor is manufactured for many years based on such product design is engaged in Abundant practical experience and professional knowledge, and coordinate the utilization of scientific principle, positive research and innovation in addition, with Phase founds a kind of new treadmills, can improve general existing treadmills so as to more practicality Property.Through constantly research, design, and Jing after studying repeatedly sample and improve, create finally really The present invention having practical value.
