Abstract: A fitness/medical device assisting the movement of the lower limbs during the walking activity is substantially composed of brackets firmly connected to the shoes, a set of substantially rigid rods (7, 7A) connecting the brackets with articulation joints (6, 6A, 8, 8A, 9), elastic or inextensible cables for connecting the brackets, and at least one spring (5) acting between the rods and the connecting cables. The shape and joints of the various components of the kinematic mechanism allows accumulating the energy produced by one of the lower limbs when getting in contact with the ground, in order to give it back to the other lower limb when lifting from the ground, so producing a great reduction of the energy needed in the walking activity and at the same time promoting the acquisition of a correct posture.

Abstract: A fitness/medical device assisting the movement of the lower limbs during the walking activity is substantially composed of fastening means firmly connected to the shoes, of a set of substantially rigid rods (7, 7A) connecting said fastening means with articulation joints (6, 6A1 8, 8A, 9) of further means for connecting said fastening means, and of elastic means (5) acting between said rods and said connection means. The shape and joints of the various components of the kinematic mechanism allows accumulating the energy produced by one of the lower limbs when getting in contact with the ground, in order to give it back to the other lower limb when lifting from the ground, so producing a great reduction of the energy needed in the walking activity and at the same time promoting the acquisition of a correct posture.

Abstract: A braking system includes a central sprag, connected and perpendicular to the handlebar, projecting towards the front side of the cycle. At the end of the sprag, a terminal is inserted, free in rotation and equipped with two side holes in the lower part through which the flexible metal cable is inserted, which will be connected outside to the common levers activating the front and rear brakes of the vehicle. At the opposite end, on the contrary, the two lugs of the cable will be directly connected to the ends of the knobs of the handlebar. With the adjustment in length of the flexible cable connected to it, relating both to the front and rear braking device, activating one of the two cables placed in the front of the knobs of the handlebar will also pull the complementary cable by the rotation and consequent draw of the mobile central body, so getting a braking action also on the opposite wheel.

At the end of the sprag, a terminal is inserted, free in rotation and equipped with two side holes in the lower part through which the flexible metal cable is inserted, which will be connected outside to the common levers activating the front and rear brakes of the vehicle. At the opposite end, on the contrary, the two lugs of the cable will be directly connected to the ends of the knobs of the handlebar. With the adjustment in length of the flexible cable connected to it, relating both to the front and rear braking devices, we'll obtain that, activating by traction one of the two cables placed in the front of the knobs of the handlebar, the complementary cable will be similarly pulled by the rotation and consequent draw of the mobile central body, so getting a braking action also on the opposite wheel.
