The front ends of a pair of extension arms are pivoted to the bottoms of the supporting arms, the rear ends of the extension arms are matched with pulleys in a sliding mode, and the supporting arms are provided with a slide-matching sleeve rod to adjust different distances among the front ends of the extension arms and the front ends of the connecting rods.

Description

Elliptic is trampled fitness equipment

The utility model relates to a kind of sports equipment, particularly a kind of override type fitness equipment.

General override type sport and body-building device includes a pair of pedal and is pivoted to a base, and this pedal can only be made the up-and-down reciprocating shift action, and can't do other track form motions.

The purpose of this utility model is to provide a kind of elliptic to trample fitness equipment, and it can make pedal more adapt to the motion of various exercise, improves motion mode, and makes the user that more selectivity be arranged.

Utility model is achieved in that a pair of support arm top is pivoted to preceding pivot, and a pair of crank is pivoted to the back pivot, and the pair of links front end is pivoted to the support arm rear end and then is pivoted to crank, and this connecting rod can form the reciprocating type of general ovalize and move.

One resistance mechanism is incorporated into connecting rod; Resistance mechanism comprises that a weighting distribution wheel is articulated on the base rotationally, and a belt links weighting distribution wheel and crank; One pulley is fixed in crank and can rotates together with crank, and another belt is bonded to pulley with weighting distribution wheel; Weighting distribution wheel comprises a truckle, and is linked to pulley by another belt pulley; A pair of adjutage front end is pivoted to support arm bottom, and this rear end to adjutage is then sliding to be fitted on the pulley and can move with respect to connecting rod, and connecting rod is pivoted to a pivot member in the middle of the support arm, and the front end of pivot member and adjutage has different distance apart from preceding pivot; This can establish a sliding supporting bar to the support arm bottom.

The syndeton of the utility model support arm, crank, connecting rod and front and back pivot, connecting rod can be formed more help the oval-shaped reciprocating type mobile of body building, even pedal can form oval motion track, and the size of the ellipse shape motion track of its sliding supporting bar structure adjustable pedal, the body-building action needs that more help the user, the setting of its adjustable resistance mechanism, the resistance size that puts on crank and pedal can be regulated by user's requirement, in the hope of the bigger effectiveness of fitness equipment performance.

The concrete structure of utility model is provided by following examples and accompanying drawing thereof.

With reference to Fig. 1,2,3,4, elliptic is trampled fitness equipment and is comprised a base 10, a pivot 11 and a back pivot 12 before base 10 has one.17 ends of a pair of support arm are pivoted to preceding pivot 11, and a pair of crank 21 is arranged on pivot 12 places, back and can rotates around back pivot 12.One pulley 18 is fixed to crank 21 and also can rotates with respect to back pivot 12.A pair of handle 15 can be arranged on 17 of support arms end and with an arm swing, maybe can be arranged on above the base 10 and is fixed handle.The bottom of support arm 17 is established a sliding supporting bar and is utilized retaining element 191 to be fixed.Pair of links 20 front ends utilize pivot member 22 to be pivoted in the middle of the support arm 17, its rear end then is pivoted to crank 21, connecting rod 20 front ends can be swung with support arm 17, its rear end then can be done the action that rotates of circumference formula with crank 21, so makes this can form the reciprocating type shift action of general ovalize to connecting rod 20.This respectively establishes a pulley 23 to crank 21.A pair of pedal 24 can be set directly on the connecting rod 20, does the trample action of elliptical form for the user.This connecting rod 20 also can be formed directly in pedal and does not need to set up in addition pedal.

A pair of adjutage 25 front ends utilize pivot pin 28 and are pivoted to sliding supporting bar 19, or directly are pivoted to the bottom of support arm 17.The rear end of adjutage 25 then is crossed on pulley 23 and can moves with respect to crank 21, is best viewed in Fig. 4 and Fig. 5.Respectively establish a pedal 24 on this adjutage, make pedal 24 also can form oval-shaped moving rail and become mark.And this pivot pin 28 or sliding supporting bar 19 can be adjusted pivot pin 28 or slide supporting bar 19 apart from the relative distance between crank 21 and the pivot member 22 with respect to the adjustment action of support arm 17, so promptly can adjust pivot pin 28 or sliding supporting bar 19 apart from the distance between the pivot member 22, thereby can adjust the size of the oval motion track of pedal 24.

One weighting distribution wheel 30 and a truckle 33 (Fig. 2,3) are inserted into base 10 tail end places rotationally with a pivot pin 38.One belt 31 combines

pulley

18,33, makes the rotational action of crank 21 can drive weighting distribution wheel 30 rotations.Another belt 32 is adjusted line 34 by one and is bonded to an adjustment button around weighting distribution wheel 30, so that can adjust the resistance that is applied to weighting distribution wheel 30 of belt 32, so can apply resistance to crank 21 and pedal 24.The user can adjust button and be adjusted to suitable resistance by mat.The weighting distribution wheel 30 that lift in this place is a kind of preferred embodiment of resistance mechanism, also can apply resistance as resistance elements such as hydraulic pressure, pulling force or elastic drag ropes by other resistance mechanism.

During action, shown in Fig. 4,5, when the user tramples pedal 24, can order about support arm 17 and connecting rod 20 and make oval-shaped reciprocating type shift action.Because the distance of pivot 11 is different before the distance of pivot member 22 and pivot pin 28, so the amplitude of oscillation of pivoting lever 22 and pivot pin 28 is also different, thereby adjutage 25 can move with respect to connecting rod 20 with pedal 24 with making the different amplitudes of oscillation, makes the elliptical path of pedal 24 can do different variations.This sliding supporting bar 19 support arm 17 is relatively adjusted, and apart from the relative distance between the pivot member 22, thereby can adjust the displacement of pedal 24 with respect to connecting rod with adjustment pivot pin 28, and the size that can adjust the track that the ellipse of pedal 24 moves.
