Definitions

  • the present disclosure relates to the field of exercise pedal assemblies. It is known that exercise is important to avoid the risk of heart disease and stroke and, of course, to improve one's quality of life. Several medical studies strongly recommend that older people get about 3 hours of physical activity per week, or about 30 minutes per day.
  • Pedal assemblies are specially designed to care for the health of sedentary people, who often sit all day at their desk, or in an armchair for older people.
  • the leg movements are natural and do not cause forced postures.
  • Physical exercise promotes the circulatory system and strengthens the bones, increases leg flexibility and arm strength, helps control weight and cholesterol levels, and reduces high blood pressure.
  • Pedal assemblies are also suitable for rehabilitation after an injury and are very effective in the treatment of arthritis pain. Persons who have undergone operations on their knees or for other injuries find a suitable solution due to their low impact during physical exercise and the ability to adjust the resistance.
  • the present disclosure relates to a small exercise device located under a piece of furniture, the device being controlled by software, running on a general purpose computer, which provides a computerized incentive to continue exercising.
  • the elliptical motion solutions allow the circular motion of the cranks to be transformed into an elliptical motion, in order to reduce the “dead” running distance during the rear lift, and to enlarge the length of the crank during the “work” stroke, which reduces the effort.
  • This elliptical motion is imposed on the pedal by the fact that the crank folds back on itself, thus avoiding the amount of unnecessary movement.
  • Circular motion solutions concern the driving of a flywheel by a pedal assembly ensuring a circular motion, like on a bicycle.
  • the present disclosure relates to this second type of exercise pedal assemblies, and more particularly, circular motion exercise pedal assemblies that may be used under a table or a desk, limiting the extent of the vertical movements of the legs.
  • the device comprises two main wheels, each of the wheels being connected to a different pedal, and two connecting rods, the distal end of each connecting rod being connected to each main wheel and the proximal end of each connecting rod being connected to the body of the exercise device.
  • the connecting rods make it possible to move the two main wheels on a horizontal axis.
  • the invention also relates to a mechanism within an exercise device that allows both elliptical and circular motion of a pedal in the exercise device.
  • the mechanism comprises: a main wheel connected to a pedal; a connecting rod connected to the exercise device and to the main wheel.
  • the trajectory of the motion of the pedal is elliptical or circular depending on the element connected to the connecting rod.
  • U.S. Pat. No. 5,490,824 describes another example of a limb exercise device comprising an outer wheel housing and an inner wheel assembly in the outer wheel housing. It comprises friction elements arranged between the contact surfaces of the outer wheel housing and the inner wheel, as well as actuating elements arranged in an opposing way on two sides of the inner wheel.
  • the inner wheel may be rotated relative to the outer wheel housing by pushing or pedaling to produce frictional force or resistance and thus helps the user to conveniently perform hand or foot exercise on a desk or on the floor or ground.
  • the present disclosure overcomes these difficulties by proposing an exercise device that can operate under a desk, table, or other piece of furniture providing an effective and non-fatiguing workout.
  • the present disclosure allows a user to concentrate on daily tasks during exercise periods.
  • the present disclosure relates to an exercise device comprising a pedal assembly, coupled to a braking device, characterized in that it comprises a housing without a saddle or any other seat through which a main transverse axle passes, arranged at a height of between 120 and 170 millimeters from the support plane on the ground.
  • the axle is coupled on either side of the housing to a disc-like plate carrying an eccentric transverse axle.
  • the eccentric axles are oriented diametrically opposed relative to the main transverse axle.
  • Each of the eccentric axles are articulated relative to a connecting piece with a pedal formed by a plate articulated relative to the connecting piece by a pivot parallel to the longitudinal axis of the plate to allow movement of the plate between a horizontal active position and a storage position where it is folded against the vertical face of the housing.
  • the main axle driving a flywheel is received in the housing.
  • the distance between the main axle and a secondary axle is between 30 and 40 mm, more preferably between 34 and 36 mm.
