Abstract

Exercise machine in shape a so-called elliptical trainer comprising a base frame (1) with two rails mounted parallel to each other on the ground (2) and an upwardly extending column (3), wherein on the column (3) two arm levers (4) are pivotally mounted and a crank wheel (6) is provided on the two footrest bars (9) are articulated against each other angular offset, whose the crank wheel (6) opposite ends (15) along the rails (2) of the base frame (1) via rollers (16) displaceable are, and a transmission linkage (12) for coordinating the pivoting movement of the arm levers (4) with the movement of the Fußauflagestangen (9), characterized in that at the in the area of upwardly extending column (3) lying ends (23) of the rails (2) another pair of rollers (26) is arranged, which when pivoting the rails (2) at the distance to the first roller pair (25) with the ground in engagement comes.

Description

The Invention is directed to a training device in the form of a so-called Elliptical trainer comprising a base frame with two mounted on the ground parallel rails and one upwards extending column, being at the column two arm levers are pivotally mounted and provided a crank wheel is at the two footrest bars are angularly offset against each other, whose the crank wheel opposite ends along the rails of the base frame are displaceable, and a transmission linkage for coordination the pivotal movement of the arm levers with the movement of the foot support bars.

Such a training device is off DE 10 2004 055 909 A1 known. This known training device has pivot bearings in such a way that the upwardly extending column with the arm levers on the one hand and the rails on the other hand are mutually pivotable, so that the entire assembly is collapsible. In the region of the lower end of the upwardly extending column, ie at the front end of the housing, two rollers are provided which serve to move the exercise machine in the manner of a sack truck, wherein a part of the weight is collected by the two rollers and the other part of the weight must be absorbed by the person pushing.

The previously known arrangement is on the one hand therefore disadvantageous because the Interrupting the sliding movement when, for example, an in-the-way Cleared away obstacle must be placed, the entire arrangement on the ground and to continue must be raised again because the person pushing with a part of the weight is loaded and because the whole arrangement is in the folded state is not sufficiently stable, so there is a risk of injury, especially bruising.

Of these, Based on the invention, the object is based, such To make training arrangement easily and safely displaced.

These Task is inventively characterized solved, that at the lying in the region of the upwardly extending column Ends of the rails another pair of rollers is arranged, which when pivoting the rails at a distance from the first pair of rollers engaging the ground.

This leads to, that in the folded state according to the invention, the training arrangement on four Rolls rests and in this condition both comfortably and without weight moved by the operator as well as left stable can be. The arrangement thus needs at the interruption of It does not have to be put down on the ground nor does it have to be Do not lie on the floor for storage or lean against a wall become.

to Achieving a stable final state after folding can on the one hand a locking device for fixing the crank wheel and / or be provided of the transmission linkage and On the other hand, a locking device for fixing the folding-top pivot bearing.

following The invention is based on a preferred embodiment in connection closer to the drawing described. Showing:

1 a schematic side view of a training device according to the invention,

2 a 1 corresponding representation with solid guide rods and

3 a 1 corresponding representation of the training device in the sliding or storage condition.

An illustrated in the drawing training device in the manner of an elliptical trainer includes a base frame 1 with two mounted on the ground, parallel to each other rails 2 and one from the base frame 1 away upwardly extending column 3 , at the two arm levers 4 via a swivel joint 5 are pivotally mounted, and a crank wheel 6 which is a pivot bearing 7 is rotatable. At the crank wheel 6 are over swivel joints 8th 180 ° angle offset footrest bars 9 pivoted. Each footrest bar 9 has a foot plate 10 up, which has an upwardly extending approach 11 with the footrest bar 9 connected is.

transmission linkage 12 are pivotable respectively to the lower end of each arm bar 4 over a pivot bearing 13 connected and on the other hand via a pivot bearing 14 below the footrest plate 10 ,

At the far end 15 every footrest bar 9 is a role arrangement 16 provided with a cover 17 is provided.

The roller arrangement 16 allows one of the rotational movement of the crank wheel 6 derived float in the direction of the double arrow 18 and a pivoting movement in the direction of the double arrow 19 the rear end 15 the footrest bars 9 ,

For transporting or storing first, as in 2 shown, from the rear end 20 the inside there are hollow rails 2 guide rods 21 pulled out, the extension of the lever arm for subsequent pivoting up the rails 2 enable. They are about a locking screw 22 set in its extended position.

In the area of the inner end 23 the rails 2 is a swivel joint 24 trained, which makes it possible, the rails 2 opposite the base frame 1 , as in 3 shown, hochzuschwenken.

In the area of the front end of the base frame 1 is a first pair of roles 25 intended. Another role 26 is at the front end 23 every rail 2 arranged so that thereby a second pair of rollers 26 is formed and the training device in the folded state then stable on a total of four rollers or two pairs of rollers 25 . 26 rests. It can be easily and effortlessly moved and stored in this state. The fixation of the swivel joint 24 in the folded state takes place via a locking lever 27 so that unintentional unfolding is reliably prevented. In the unfolded ready state, the swivel joint rests 24 on a leveling foot 29 ,

To facilitate the swiveling up and dampening the swiveling down, gas fields are similar to those in a motor vehicle trunk 28 provided, extending from the bottom of the rails 2 to a strut of the base frame 1 extend.

At one the crank wheel 6 encompassing housing arc is a detent button 30 provided by means of which the crank wheel 6 locked or locked and also the transmission linkage 12 as well as the foot support bars 9 can be set in a predetermined position. This locking or fixing takes place in particular before the folding up of the rails 2 ,
