Description

 Multi-rod pedal exercise device  

The invention relates to a rod and pedal structure of a multi-rod pedaling device, in particular to a multi-rod pedaling device structure capable of realizing natural stepping.

The pedal exercise device is a common exercise device in the field of fitness machines. Because of its simple use, the walking and running movements of the hands and feet are like the elliptical shape of the pedals, so the industry calls it Elliptical machine, trampling elliptical fitness machine or spacewalker, elliptical machine as a kind of equipment for cardio-pulmonary exercise is very good, has been loved by many users and professionals. The elliptical's slope design, resistance-resistance adjustments, orchestrated movement patterns, and the ability to exercise on a certain tissue muscle in the lower extremities make it a common exercise device in professional gyms and home living rooms. The biggest feature of the elliptical machine is that there is no point in the knee joint when the human body uses it to exercise. It can not only prevent, reduce and relieve the pain of cervical spondylosis, frozen shoulder and upper back, but also avoid running. The resulting impact better protects the joint for a better safety factor. The elliptical machine can exercise and stimulate the regulation of the sciatic nerve, enhance the endurance and strength of the waist muscles, and achieve the effect of body sculpting on the stimulation of the buttocks, thighs, side waist and small abdomen.

However, most of the current elliptical machines are composed of a crank, a crank arm, a roller, an armrest swing arm, a pedal swing arm, and a linear slide. For example, a conventional elliptical machine is shown in FIG. 4 and FIG. The rod 2' comprises a first link 21', a second link 22', a roller 6', a grip link 51', a pedal link 52', and a linear slide 7'. The user's foot exerts a force on the pedal. During the motion cycle, the movement curve 8' of the pedal link 52' approximates the elliptical movement path (as shown in Fig. 6 - the foot pedal of the multi-rod pedal exercise device The movement diagram of the rod is shown in the figure), but the elliptical motion is designed to simulate the step. When the step is raised, the upper arc is not drawn, so the elliptical step is less in line with the step. .

It is customary for the elliptical machine pedal to move up and down the up and down position, depending on the circular motion of the first link 21' and the reciprocating linear and rocking motion of the second link 22', forming an elliptical step movement trajectory, which is not a multi-rod type that realizes natural stepping. The structure of the pedaling device.

In view of this, how to develop a multi-rod pedaling device structure that is different from the conventional ergonomic pedal pedaling movement stroke and realizes natural stepping is a problem that is urgently needed in the related art.

Generally, the elliptical motion is designed to simulate walking, but the user's foot exerts a force on the pedal, and the elliptical trajectory generated by the movement of the lower limb during the movement period is similar to the elliptical movement trajectory, when the human body moves the leg. At the time, the upper arc is not drawn, so the elliptical step movement trajectory is less in line with the walking trajectory. How to develop a multi-rod pedaling device structure that realizes natural stepping is urgently required by the related art. The problem that needs to be solved.

A multi-rod pedaling device is provided, comprising: a base that stands on a floor surface; a left four-segment link and a right four-segment link are mounted to the base by a flywheel in conjunction with each other; The flywheel is fixed to the base, and one of the left four-segment link and the right four-segment link are pivotally connected to two sides of the central axis of the flywheel, and the left four-section link and the right four-section link are respectively The other end is pivotally connected to the two sides of the first pivot seat of the base, and the first pivot seat is fixed to the base; a left hand grip link and a right hand grip link are respectively pivotally connected to the base a second pivoting link; a left pedal link and a right pedal link pivotally connected to the left hand grip link and the right hand grip link pivot; the left fourth link and the right fourth a segment connecting rod, wherein one segment is respectively provided with a left roller and a right roller; the left fourth segment link and the right fourth segment link, wherein one segment is pivotally connected to the left pedal link and the right pedal link respectively a pivoting seat; and a left curved rail and a right curved rail are respectively fixed to the base, and the left roller and the right roller are respectively subjected to the left curved rail and the right The arcuate rail is guided to slide along a defined trajectory.

The present invention provides a multi-rod multi-rod type pedaling device, which is different from the conventional foot pedal in comparison with the conventional pedaling device. The pedal pedaling movement stroke of the treading device, the height difference caused by the reciprocating oscillating motion of the fourth link in the motion cycle, and the height difference caused by the reciprocating oscillation of the third link, and the roller of the third link is subjected to the curved rail Guided to slide along a defined trajectory, so that the pedal pedaling movement stroke of the multi-rod pedaling device of the present invention produces a multi-rod type that is different from the ergonomic natural step by different from the movement curve of the conventional pedaling device. The structure of the pedaling device.

The reason is that the present invention has been studied in view of the above problems, and after a long period of design and development, the "multi-rod pedal exercise device" of the present invention is completed to solve the unfulfilled effect of the conventional pedal exercise device.
