Description

Body-building stepping machine

The utility model relates to a kind of body-building treadmills, refers to a kind of pedal of trampling the tool resistive drag force alternately of borrowing especially with the exercise strength of one's legs time, doublely can train arm strength, to reach the Improvement type body-building treadmills of body-building purpose.

Known motion is with treadmills (also claiming fitness climber), and mechanism is simple, volume is little because of having, and does not take up space, be easy to carry and the spendable whenever and wherever possible advantage of the old and the young irrespective of sex, and very in fashion recently.But this kind simple form treadmills is No. 209386, Taiwan patent announcement and No. 211719 those disclosed herein for example, normally by pair of pedals, an a pair of oil hydraulic cylinder and a base constitute, and the width of its bearing-surface only about with shoulder with wide, only about 50 centimeters long of length, and both sides height difference, so that when the user moves at the station thereon, the gravity less stable, safety will be waved the maintenance balance by both hands, otherwise slips easily.For avoiding this situation to take place, someone adds the handrail of supporting that balance is used in treadmills the place ahead, as No. 209385, Taiwan patent announcement and No. 212303 those disclosed herein or borrow in addition and independently subsidize frame or handrail and keep stable to help, but so do the volume and the weight that then will increase treadmills integral body, and need bigger collection space, become and be not easy to carry and collect.In addition, above-mentioned known treadmills only can supply leg exercise usefulness, uses for arm movement and can't hold concurrently.Though the public swingable handle that row arm movement when can move in marking time is provided for No. 212303 that leans on of Taiwan patent, this handle and above-mentioned support handrail take up space equally, hinder collection.

Main purpose of the present utility model is to provide a kind of body-building treadmills of improvement, and having flexible pull rope mechanism can cooperate the motion of marking time to do arm motion simultaneously for the user.

Of the present utility model time a purpose is to provide a kind of body-building treadmills, and its flexible pull rope mechanism can be concealed in the pedal below, and does not take up space in addition, and this flexible pull rope mechanism also can be as flexible handle, with the auxiliary balance that keeps health.

A purpose more of the present utility model is to provide a kind of body-building treadmills, has simple leverage to cooperate the action of pedal.

Be a kind of body-building treadmills of realizing that the purpose of this utility model proposes, be by a base, a pair of with the front end pivoted freely pivot prop up the pedal of both sides in the support sector of base front end, but a swing is hubbed at the leverage on the base freely, and a pair of scalable and shake and be hubbed at the anterior oil hydraulic cylinder with the pair of pedals bottom surface of base freely and constitute;

It is characterized in that: this pair of pedals inside respectively is provided with a free end and stretches out before the pedal other parts of foreign side and then borrow assembly pulley to support into scalable pulling retractility rope hauling device freely.

As for other purposes of the present utility model and characteristics, can be elaborated and more can be understood by following conjunction with figs..

Now be described in detail as follows with regard to specific embodiment of the utility model according to accompanying drawing:

Fig. 1 is the perspective view of the utility model treadmills;

Fig. 2 is partly cut-away's vertical view of the utility model treadmills;

Fig. 3 is the partial cross sectional side elevation view of the utility model treadmills;

Fig. 4 be another embodiment of the utility model treadmills want portion's schematic diagram.

At first, please refer to Fig. 1 and Fig. 2, the utility model mainly is by a base 1, a pair of front end borrows horizontal cross shaft 13 to prop up the pedal 2 that is held in base 1 front end pivotly, but one borrows pivot 14 swings ground to be located at the rocking lever 3 of base 1 front portion in order to supporting pair of pedals 2, a pair ofly is located at above-mentioned pair of pedals 2 and slightly tramples the oil hydraulic cylinder 4 of resistance and a pair ofly scalablely hide the flexible rope hauling device 5 that an end that is located at the inside of above-mentioned pair of pedals 2 and has handle for example or a draw ring 51 extends outside pedal 2 front ends freely and constitute in order to invest pedal below the rear portion and between base 1 front portion.

In the present embodiment, base 1 is to make approximate H font and at the perpendicular pedestal that is provided with two

upright post

11 and 12 of front end with the flat iron pipe, but held stationary like this and reduction volume and weight, but obviously as can be known, this base 1 can adopt any material to make various suitable shapes to keep stable.

Pedal 2 normally is made of the short pedal 22 of broad that a prolate shape hollow pedal panel seat bar 21 and is located at a bar 21 rear portions, in the present embodiment, pedal base bar 21 is to adopt the flat iron pipe and pedal body 22 is adopted plastic shaping and formed, but obviously both also can adopt as the industrial plastic material of aluminium alloy and other sufficient intensities etc. and make as can be known, and both can make with same material or different materials.In addition, seat bar 21 also can be one-body molded with pedal body 22.Above-mentioned pedal body 2 be with the front end of pedal base bar 21 borrow trunnion axis 13 rotationally pivot prop up and be in pillar 11 both sides in base 1 the place ahead as Fig. 1 and one on the other state shown in Figure 3.

Rocking lever 3 is to make with the channel of section ㄇ type, but and borrow pivot 14 swings ground to be articulated on the pillar 12 of base 1, the left and right sides of lever 3 is respectively equipped with before one, the roller 32 that is supported on spools 31 after just contacts with the bottom surface of pair of right and left pedal base bar 21.

A pair of oil

hydraulic cylinder

4,4, it is articulated in the front portion of base 1 and the bottom surface, inclined to one side rear portion of pedal 2 with its cylinder pressure end and piston rod 41 ends respectively movably as the oil hydraulic cylinder of known technology, and can with being stepped on up and down of pedal 2 stretch and pivot moving.

Rope hauling device 5 is arranged in the hollow bulb of two pedal base bars 21, as shown in Figures 2 and 3, and comprise: a pair of rotatable front and back freely are disposed at the

dual pulley

52,53 of level in the bar 21, one rotatably is arranged at a bar 21 vertical guide idlers 54 foremost, and one end is borrowed in the fixing present bar 21 of steady pin the other end on the steady pins 57 of rear portion then to be the double cross shape to walk around after above-mentioned two

horizontal trolleys

51,52 the retractility stay cord 55 of pulling out outside the bar 21 at guide wheel 53 by vertically.The end of pulling out that draws retractility stay cord 55 is that free end links to have between activity safety hook 56, two hooks 56 and hangs with leader 51 dismantledly.This handle 51 also can be made two other handles or draw ring 51A as shown in Figure 4.

Again, a counter or electronic watch 6 optionally can be installed in the place ahead pillar 11 tops of base 1.

The utility model is because of having structure as above, the user is except that can taking exercises as habitual treadmills both feet pedal, both hands can hold handle 51 simultaneously or 51A is resisting the elastic telescopic strength of stay cord firmly to stretch flexible rope to do the usefulness of arm movement, again after the motion, rope can retraction the pedal base bar inner and only hook end expose outside the bar, and handle also can directly be folded on the pedal or be unloaded down and be stacked and placed on the pedal, thereby does not increase the overall volume of treadmills in fact and can pack very compactly and collect.

More than be only to narrate with regard to the utility model one preferred embodiment, in fact, the dealer who is familiar with this skill still can not do all modifications and change in having the application's claim scope of disobeying, and all these modifications, change are when being considered as being encompassed in this case claim scope.
