Description
"MACHINE FOR EXERCISING LEGS"
The present invention relates to machines for physical exercise, and in particular to a machine for exercising legs. Prior art machines for exercising legs include a weight pack that slides in a vertical frame when lifted through a cable connected to a lever comprising a thigh rest. During the exercise the user is sitting, i.e. is in a rather unnatural position, whereby said prior art machines are poorly effective and can overload the user's joints. Therefore the object of the present invention is to provide a machine which is free from said drawbacks. This object is achieved by means of a machine whose main features are defined in claim 1, while other features are disclosed in the dependent claims.
Thanks to the footboard and handle arranged to a side of the lever, the machine according to the present invention can be used also by a user in a substantially standing position, so that he can rotate the leg in a natural manner without overloading the joints and exercising the quadricepses to the maximum of their potential, especially if the first lever is connected to the cable through a main pulley having an elliptical cam contour. A second lever provided with a tibial rest is preferably pivoted to the first lever so as to exercise, always in a natural and effective manner, the lower portion of the leg independently of the upper portion.
Other advantages of the machine according to the present invention stem from its relatively small size and its easy adaptability to the different user's heights.
Moreover, the machine can be provided with additional symmetrical components to exercise also the other user's leg, thus saving room and components with respect to two machines for exercising a single leg.
Further advantages and characteristics of the machine according to the present invention will be clear to those skilled in the art from the following detailed and non-limiting description of an embodiment thereof, with reference to
the annexed drawings wherein:
Fig.l is a front perspective view of the machine; Fig.2 is a side view of the machine of Fig.l; and Figs.3 to 6 are side views of the machine of Fig.l during use. With reference to figures 1 and 2, there is seen that a machine according to the present invention conventionally includes a weight pack 1 that is slidable along a vertical frame 2 and can be lifted through a cable 3 that passes over a plurality of idle pulleys 4 until it connects to a main pulley 5 pivoted to a post 6 rising from a base 7. The main pulley 5 has an elliptical cam contour and is connected to a first lever 8 pivoted on the opposite side of post 6, which is therefore located between the main pulley 5 and the first lever 8. The first lever 8 includes a telescopic extension 9 that can be extended or retracted by rotating a knob 10. The telescopic extension 9 is in turn provided with a thigh rest 11 having a substantially cylindrical shape. A second lever 12 is pivoted to the telescopic extension 9 of the first lever 8 and is provided with a tibial rest 13 having a substantially flat shape. Rests 11 and 13 are preferably padded. The second lever 12 is connected to resilient pulling means 14, in particular a coil spring, through a second cable 15 that passes around an auxiliary pulley 16 coaxially pivoted to the fulcrum of the first lever 8. The resilient pulling means 14 are secured to the telescopic extension 9 and are substantially parallel to the first lever 8. A footboard 17 is arranged to a side of post 6, so that levers 8 and 12 are located between footboard 17 and post 6. Footboard 17 is secured to a slide 18 that can slide and be locked at any position along a vertical guide 19. Resilient pulling means 20, in particular a coil spring, pull slide 18 upwards to facilitate the raising of footboard 17. A handle 21 is mounted on a post 22 located behind footboard 17, such that post 22 and the vertical guide 19 are arranged along a plane substantially perpendicular, to the rotation axis of the first lever 8. The machine according to the present invention preferably includes further first and second levers 8', 12', main pulley 5', thigh rest H1 and tibial rest 13' that are connected to weight pack 1 through the first cable 3 or a further first cable, are substantially equal to the corresponding components of the system that includes the first and
second levers 8, 12, but they are arranged in a perfectly symmetrical manner with respect to a midplane passing through the vertical frame 2. For the sake of simplicity, figures 2 to 6 do not show some of these symmetrical components.
With reference to figures 3 to 6, there is seen that a user 23, in a substantially standing position, can place his left foot 23a on footboard 17 and hold handle 21 , whereafter he places his right leg 23b on the thigh rest 11 and tibial rest 13. The right leg 23b is bent backwards in a starting position, shown in Fig.3. To this purpose, handle 21 and footboard 17 are located respectively above and below the fulcrum of the first lever 8. In performing the exercise, the user rotates forward his right leg 23b, which therefore takes the sequence of positions shown in figures 3 to 6. During this rotation, the thigh of the right leg 23b rotates the first lever 8, overcoming the weight of weight pack 1, whereas the lower portion of the right leg 23b rotates the second lever 12, overcoming the pull of the resilient pulling means 14. In order to exercise the left leg, the user can hold the further handle 21', place his right foot on the further footboard 17' and the left leg on the further first lever 8' and further second lever 12', so as to perform the same movement yet with the left leg.
Possible additions and/or modifications may be made by those skilled in the art to the embodiment described and illustrated above, yet without departing from the scope defined by the appended claims.
