The postposition elliptic motion machine has simple and reasonable structure and convenient use.

Description

Rearmounted elliptical exercise machine

(1) technical field

The utility model relates to a kind of health and fitness facilities, especially a kind of rearmounted elliptical exercise machine, and this elliptic motion function makes the user move his pin along predetermined elliptical path, the knee motion of natural imitation and ankle motion.

(2) background technology

Existing elliptical exercise machine is attempted the knee motion and the ankle motion of natural imitation, but fails to provide accurate imitation.

(3) summary of the invention

The purpose of this utility model is to provide a kind of rearmounted elliptical exercise machine that more meets ergonomics.

For achieving the above object, the utility model is by the following technical solutions:

A kind of rearmounted elliptical exercise machine, comprise a body frame, one damper, one linkage, two treadles and two forks, two forks are hubbed on the column of body frame front portion, the upper end of each fork is the Handheld Division, the front end of each treadle articulates with the lower end of a corresponding fork respectively, the stage casing of each treadle is respectively equipped with a pedal position, it is characterized in that: linkage comprises one first bent axle, one second bent axle, two first connecting rods and two second connecting rods, first bent axle and second bent axle are hubbed on the rear portion of body frame respectively, first bent axle or second bent axle connect damper by a tape handler, keep rotating synchronously by a synchronous mechanism between first bent axle and second bent axle, the two ends of first bent axle are respectively equipped with one first crank, 2 first cranks are all along the radially extension of first bent axle and reverse mutually, the two ends of second bent axle are respectively equipped with one second crank, 2 second cranks are all along the radially extension of second bent axle and reverse mutually, first crank is parallel with second crank, the rotation end of each second crank articulates with an end of a corresponding first connecting rod respectively, the other end of each first connecting rod articulates with an end of corresponding second connecting rod respectively, the other end of each second connecting rod articulates with the rear end of corresponding treadle, and the rotation end of each first crank and the stage casing of second connecting rod articulate.

Technique scheme can also be further improved by following technical measures.

Lazy-tongs are chain-drive mechanism or tape handler, and gearratio is 1.

The utility model is simple and reasonable, and is easy to use, can be combined into a kind of motion of more coordinating more naturally to the motion of pin and hand, can effectively reduce athletic injury, comfortableness during lifter motion and smooth degree.
