Abstract

The utility model provides a folding treadmill, comprising a front bottom bar, two treadles and an upright column, wherein the upright column is connected on the upper side of the front bottom bar, a middle bottom bar is pivoting-connected on the lower inner side of the front bottom bar, of which the end is connected with a rear bottom bar, the two treadles are connected on the bilateral sides of the bottom portion of the upright column via pin joint , one ends of the treadles are provided with pedals, damping bars are connected on the almost middle position of the treadles via pin joint, the upright column is connected to the inner side of the upright column via pin joint, an armrest is connected at the upper end of the upright column, both sides of the middle end of the upright column are respectively connected to the top end of the damping bars via pin joint, the lower end of the upright column is connected to a diagonal rod via pin joint, and the end of the diagonal rod is connected to the middle portion of the middle bottom bar via pin joint. The treadmill does the turn action by toggling the middle bottom bar, enabling the front end of the diagonal rod to lift, and shifting the armrest down via lever-type of the upright column. The treadmill pulls the two damping bars via the upright column, enabling the treadles to change from slanting to closely stance typed closing, and finishing the folding action via a single step.

Description

The folding treadmills

Technical field

The utility model relates to body-building apparatus, is meant a kind of folding treadmills especially.

Background technology

Treadmills is the equipment of indoor sport body-building, occupies certain interior space when launching owing to it, therefore progressively develops the treadmills that folding, common folding treadmills is because necessary one one assembly folding, be divided into several roads step and finish, for the user, and inconvenient; Chinese patent " the training aids " (patent No.: mainly be ZL99254879.9), do each assembly folding of interlock, reach convenient and safe practical effect with one step in the interlock mode but folding is marked time.

Summary of the invention

The utility model main purpose is to provide a kind of folding treadmills, can do folding by other assembly of interlock by single start, and do not need the repeatedly action of folding, and account for littler space after the folding, its structure more above-mentioned " training aids but folding is marked time " is more simple.

For achieving the above object, a kind of folding treadmills described in the utility model, bottom bar before comprising one, bottom bar in one, one back bottom bar, one column, one brace, two ends set firmly treadle and two damper rods of pedal, bottom bar front end and preceding bottom bar middle part flexibly connects in being somebody's turn to do, end is fixedlyed connected with the back bottom bar, bottom bar top before this column is fixedly connected on, this brace lower end is fixedly connected near the middle bottom bar middle part, this treadle front end is articulated in the column two bottom sides, this folding treadmills also comprises a upper pillar stand, the middle part of this upper pillar stand and column top flexibly connect, this upper pillar stand lower end and brace top flexibly connect, and these damper rod two ends are articulated in treadle middle part and upper pillar stand middle part respectively.

The top of this damper rod also can be articulated near the upper end of this brace.

During folding, stir bottom bar in this, make it do the turnover action, the brace front end is risen move down handrail according to the lever mode, and upper pillar stand affects two damper rods, make treadle transfer nearly vertical drawing close to, can finish the action of interlock folding with one step by inclination with upper pillar stand.

Below in conjunction with drawings and Examples the utility model is further specified.
