Description

elliptical machine

[technical field]

The invention relates to an elliptical machine, in particular to a free-style elliptical machine.

[Background technique]

At present, there are quite a lot of elliptical machines commonly used on the market, and these elliptical machines can only perform the function of an elliptical machine and cannot perform the function of a stepper. In addition, most of the elliptical machines can only do the elliptical machines with fixed routines and cannot adjust their travel strokes, and they cannot be freely selected as steppers.

[Content of the invention]

In view of the many shortcomings of the commonly used elliptical machines, the elliptical machine of the present invention has finally been developed after many times of research and improvement to provide a freestyle elliptical machine that can be used as a stepper or an elliptical machine.

The main structural design of the present invention includes a base with a bracket, a pivot erected on the bracket, a pair of handles connected to the pivot, and a pair of pedal rods; it is characterized in that: one pair of cranks utilizes a pivot. Set on the bracket, each of which has a shaft located away from the pivot, and the front of the pedal rod is connected to the shaft of the crank by a link, so that the pedal rod can freely adjust its moving stroke, and the pedal rod The middle part is connected to the handle.

The elliptical machine is characterized in that each handle has a handle for the user to hold.

The elliptical machine described above is characterized in that: a linkage mechanism connects handles, linkages or pedals together.

The elliptical machine is characterized in that: the linkage mechanism has a pivot set on the bracket, and a pair of cranks are fixed to the pivot and connected to the handle.

The elliptical machine is characterized in that: a resistance device can apply resistance to the pivot.

The elliptical machine is characterized in that: the resistance device includes a running wheel connected to the pivot, and a rotating body connected to the running wheel.

The elliptical machine described above is characterized in that the pedal is pivotally arranged in the middle of the pedal rod by a pivot.

The elliptical machine described above is characterized in that a link connects the bottom of the handle to the pedals.

The elliptical machine is characterized in that: the rear of the pedal rod is connected to the rear of the base by a link and a pivot.

In combination with the above, it can be seen that the beneficial effect of the present invention is that when the handle is held and positioned by the user, the user can step on the pedal rod or pedal by means of the crank to act as a stepper, and when the handle is held by the user When swinging or freely swinging, the user can step on the pedal bar or pedal to act as an elliptical machine, which is quite convenient and practical. The elliptical size of the elliptical machine can be determined by the swing range of the handle by stepping on the pedal rod or pedal.

[Description of drawings]

For further illustrating structure of the present invention, feature and practical purpose thereof, following accompanying drawing is described in detail as follows:

Fig. 1, 2: be the perspective view of the present invention;

Fig. 3, 4: be the partial exploded view of the present invention; And

5, 6, 7, 8, 9: are schematic plan views of the present invention.

[Detailed ways]

For the elliptical machine of the present invention, please refer to Fig. 1 to Fig. 5, the whole elliptical machine includes a base 10 which has a bracket 11, a pivot 12 is located at the rear 13 of the bracket 11, and a runner 20 utilizes a pivot Shaft 21 is located at the middle 14 of support 11, and a swivel 22 utilizes a pivot 23 to erect on the middle 14 of support 11, and a driven wheel 24 is fixed to pivot 23 and utilizes a link 25 such as a belt to link to Wheel 20, so that resistance is applied to wheel 20 and pivot 21. Of course, other devices such as electromagnetic brakes or hydraulic or air resistance devices can also be used to apply resistance to the runner 20 and the pivot 21 .

A pair of cranks 30 are fixed to the pivot 21 , each having a shaft 31 located away from the pivot 21 . The middle portion 41 of the pair of handles 40 is connected to the pivot 12 , and each has a handle 42 for the user to hold. The fronts 51 of a pair of pedal rods 50 are each connected to the shaft 31 of the crank 30 by a link 52, and the rears 53 are connected to an upright 16 at the rear 15 of the base 10 by a link 19 and pivot 17. , which each utilize a pivot 54 to pivot a footrest 56 at the middle portion 55 for supporting the user. The bottom 43 of each handle 40 can be connected to the pedal 56 by using another link 57 and a pivot 58 at one end for turning the pedal 56 to a proper angle.

When the handle 40 is held and positioned by the user, the user can step on the pedal rod 50 or the pedal 54 by means of the crank 30 to act as a stepper, and when the handle 40 is swung or freely swung by the user, The user can step on the pedal bar 50 or the pedal 54 to act as an elliptical machine, which is quite convenient and practical. The elliptical size of the elliptical machine can be determined by the swing range of the handle 40 by stepping on the pedal bar 50 or the pedal 54 .

Commonly used elliptical machines cannot freely choose the effect of stepper or elliptical machine. And the conventional elliptical machine all can't freely adjust its moving stroke. Cooperate with referring to Fig. 5 to Fig. 9, the present invention can further set up a linkage mechanism 60 to link together handle 40 or link 52 or pedal bar 50, and its each has a pivot 61 to be located on the support 11, two cranks 62 One end 65 of a pair of link rods 64 is connected to the shaft 63 of the crank 62, and the other end 66 is connected to the handle 40 by a pivot 67. The middle portion 41 of the pivot shaft 67 is located away from the pivot shaft 12 .
