Description

"ELLIPTICAL TRAINER WITH ERGONOMIC PEDAL UNIT"
FIELD OF THE INVENTION
The present invention relates to an elliptical trainer, and more particularly to a pedal unit for an elliptical trainer preferably with adjustable stride length. BACKGROUND OF THE INVENTION
An elliptical trainer is a stationary exercise machine used to simulate walking or running without causing excessive pressure to the joints, hence decreasing the risk of impact injuries, thanks to the fact that the user's feet remain in contact with the pedals during the exercise. Such a machine generally consists of a base holding a driving unit that includes a resistance wheel, of any known type, driven by the user through two crank mechanisms, mainly by pushing with his/her feet on substantially horizontal reciprocating bars, acting as rods, pivoted between the cranks integral with the resistance wheel and guiding/supporting members. In the case of elliptical trainers with front resistance wheel, the rear end of each bar is usually guided and supported by a slider or roller unit that reciprocates along a track formed in the base.
Furthermore, two substantially vertical handle-levers are in general pivotally connected to a post on the base, and each lever is also pivotally connected at its bottom end to the relevant reciprocating bar either directly at the front end of the latter, in case of rear- wheel trainers, or indirectly through a link rod substantially parallel to the bar, in the case of front- wheel trainers.
The stride length of the trainer is defined by the crank length, that in the simplest models is fixed at an average value selected to fit most users. More sophisticated models provide a crank length, i.e. stride length, adjustment in order to adapt the trainer to users of any height and to allow the user to perform the most suitable exercise.
Regardless of the specific type of trainer, the pedals are mounted on the bars in a way that does not satisfy the ergonomic needs of the user during the exercise. In fact, the pedals can be made integral with the bars by directly securing the pedals thereon at a fixed inclination, or by pivoting them on the bars and possibly also on the link rods.
More specifically, in the case of fixed mount it is clear that the inclination of the pedal is determined by the inclination of the bar to which it is secured, whereby also the user's ankle is forced to adapt to the varying bar angle throughout the exercise cycle. This continuous adaptation stresses the joint and may even cause imbalance of the user if the required ankle angle is beyond or close to the limit of the user's capabilities.
If the pedal is simply pivoted on the bar through a single pivot, this is even worse than the fixed pedal. In fact, the user must continuously strive to keep a balance on the pedal that is free to tilt backward and forward, and this makes extremely difficult to perform a correct exercise.
An improved pivotal mount is achieved by pivoting the pedal not only on the bar but on the link rod as well. In this way, the pedal can tilt so that the user is not forced to follow the inclination of the bar, yet the tilt range is limited and balance is not a problem. However, also this arrangement is not free from drawbacks, in particular in the case of an adjustable stride trainer.
In fact, the link rod that supports the pedal is mainly intended to couple the reciprocating movement of the horizontal bars to the reciprocating movement of the handle-levers, so as to achieve a synchronized action of the legs and arms of the user. Therefore, the resulting tilt range of the pedal is not based on ergonomic considerations but is the mere outcome of the rigid connection between the above- mentioned members. Moreover, if the stride length is adjusted by changing the crank length, either the link rod and/or handle-lever length should be adjusted, which would imply a complicated structure and lengthy adjustments, or the pedal tilt range changes as a result of said stride adjustment. SUMMARY OF THE INVENTION
The present invention is intended to overcome said drawbacks by providing a pedal unit in which a pedal has a first end pivotally connected to the relevant reciprocating bar and a second end pivotally connected to an articulated lever system connected with an end of the reciprocating bar and provided with support means suitable to reciprocate along the track together with the bar. BRIEF DESCRIPTION OF THE DRAWINGS
The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.
Fig.l is a perspective view showing the elliptical trainer of the present invention;
Fig.2 is an enlarged exploded view showing the pedal unit and how it is mounted on the reciprocating bar; Fig.3 is a side view showing the relationship between the tilt angle of the pedal and the stride adjustment;
Fig.4 is a side view showing a user that operates the elliptical trainer of the present invention; and
Fig.5 is a side view showing the detail of the pedal being tilted upward. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to Figs. 1 and 2, there is seen that the structure of the elliptical trainer of the present invention (the casing having been removed for the sake of clarity) comprises a base 10 having a horizontal frame 12, with a vertical post U extending from a first end of the horizontal frame 12 and a guide unit 13 connected to a second end of the horizontal frame 12.
Two handle-levers 15 are pivotally connected to the post 11 and a belt 14 connects them to an underlying drive unit 20 also connected to the post 11. Said drive unit 20 includes on each side a wheel 21, that can be any known resistance wheel, which is driven by the user through a crank mechanism arranged between wheel 21 and the guide unit 13. ,
The crank mechanism includes a crank 30 integral with wheel 21 and a reciprocating bar 31 having a front end pivoted to crank 30 and a rear end 34 guided by the guide unit 13. The reciprocating bar 31 carries a pedal unit comprising a pedal 32 that has a first end pivotally connected to a connection part 33 extending vertically from bar 31 and a second end pivotally connected to an articulated lever system connected with the rear end 34 of the reciprocating bar 31 and provided with support means suitable to reciprocate along the track formed in the guide unit 13.
More specifically, the support means consist of a roller unit 40 provided in the rear portion of the reciprocating bar 31 with a first pair of rollers 41 and a second pair of rollers 42, both pairs 41, 42 being movably engaged with the guide unit 13. While the second pair of rollers 42 is mounted on the rear end 34 of the reciprocating bar 31, the first pair of rollers 41 is mounted at the corner of an L-shaped tiltable support rod 51 that extends through a slot 35 formed in the reciprocating bar 31. The support rod 51 is an L-shaped rod with a long arm 511 pivotally connected with the second end of the pedal 32 and a short arm 512 pivotally connected with a connection link 43, which is in turn pivotally connected with the rear end 34 of the reciprocating bar 31. This articulated lever system thus connects the second end of pedal 32 to the rear end 34, and the tilting of the support lever 51 results in an upward or downward tilting of pedal 32 around the pivot axis of the connection part 33.
The diagram of Fig.3 shows how the length of the long arm 511 is designed to provide the maximum possible forward tilt angle A of pedal 32 when the length R of crank 30 is maximum, i.e. the longest stride is set. Upon reduction of the stride by moving radially inwards the front end pivot of the reciprocating bar 31 along the adjustment travel C of crank 30, the pedal angle A will be correspondingly reduced to adapt to the new stride length so as to maintain the user's ankle angle within an ergonomicaily correct range.
The comparison between the position of Fig.3, where the right reciprocating bar 31 is at the highest point, and the position of Figs. 4 and 5, where the right reciprocating bar 31 is at the lowest point in its reciprocal motion, clearly shows the tilting movement of the L-shaped support rod 51 that results in a corresponding upward movement of the front end of pedal 32 thus reducing the ankle angle so as to remain within an ergonomic and anatomically safe range. While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention as defined by the appended claims.
For example, it is clear that the same type of pedal unit may be applied also to a rear- wheel elliptical trainer, even without stride adjustment, and that the crank length adjustment as well as the synchronization of the handle-levers 15 with the reciprocating bars 31 may be achieved through any suitable mechanism.
