Definitions

  • the present invention is in the field of footwear suitable for cycling activity in general and more specifically for competitive and amateur sports cycling, particularly but not exclusively with reference to road or track cycle racing performed with a so-called racing bicycle.
  • Background Art Although the operation of a bicycle, hereinafter referenced by the generic expression "cycling vehicle”, is well known, there are some considerations that cast light on a basic problem in the use of a cycling vehicle and have been neglected or ignored up to now.
  • Figure 1 illustrates a cyclist who, while sitting on the cycling vehicle 1, operates a central mechanical assembly with a spur gear 2 and a chain 4, imparting an alternating motion to his thighs and pushing on a pair of pedals 3 that are articulated at the end of respective cranks, with his feet provided with specifically provided footwear, also commonly known as cycling shoes.
  • Footwear for sports cycling, or cycling shoes, of the prior art typically have a shape that allows, during the actuation of the pedal mechanism of the cycling vehicle, a broad and free rotation of the foot around the articulation of the ankle. Moreover, they have a sole whose consistency and material are selected exclusively for the purpose of protecting the foot in the region proximate to the articulation of the toes, where the foot rests on the pedal.
  • Figure 2 is a view of a typical model of cycling shoe of the prior art, constituted by a rigid sole 27, which has a consistency that is sufficient to withstand the compression or traction force applied by the foot to the pedal, and by an upper with two flaps of a soft and flexible type, which is easily deformable and is provided with low-strength breathable regions, with fastening elements which in turn are provided with closing engagement devices based on Velcro or the like and with a profile of the upper edge, at the articulation of the ankle, that is provided with an extensively padded recess that is suitable to allow the foot to rotate freely and without hindrance with respect to the leg.
  • Figure 3 is a view, in three successive positions of the crank of the mechanical assembly that propels the cycling vehicle, of the different posture assumed by the leg and by the foot of a cyclist who performs the round stroke, based on so-called ankle play, i.e., on the continuous correction, synchronized with the rotation of the cranks, of the angle formed by the foot and by the leg:
  • Figure 3a illustrates the posture, characterized by an angle ⁇ smaller than 90°, that is assumed when the crank 3 is in a position that is close to the top dead center;
  • Figure 3b illustrates the posture, characterized by an angle ⁇ equal to 90°, that is assumed when the crank 3 is substantially in a horizontal position;
  • Figure 3 c illustrates the posture, characterized by an angle ⁇ greater than 90°, that is assumed when the crank 3 is in a position that is close to the bottom dead center.
  • the figure also illustrates the inclination of the force F applied by the cyclist to the pedal.
  • the practice of sports cycling has shown that the round stroke, in addition to being effective only for a short arc of the entire movement of the pedaling stroke, can be practiced only for very short periods of time, even when performed by expert cyclists, since this technique is very difficult and tiring.
  • ankle play is performed only occasionally in competitive and amateur cycling and the supposed advantages provided by this type of pedaling stroke are extremely limited in comparison with the expenditure of energy that it entails.
  • FIG. 4 is a view of a cyclist in position on the vehicle, in the condition in which the right leg applies the maximum effort to the pedal.
  • the lower limb of the cyclist is shown in a manner that is equivalent to a system of rods constituted by the thigh 41, the leg 42 and the foot 43, which are pivoted in the articulations of the hip 44, of the knee 45, of the ankle 46 and of the toes 47.
  • the effort F applied by the muscles of the thigh 41 is transmitted, putting under stress the entire articulated system, to the hinge 47, where the resistance to the motion R of the pedal 3 is applied.
  • the effort of the muscles of the leg that control the angular position of the foot with respect to said leg is considerable.
  • Figure 5 illustrates the lower part of the right limb of the cyclist, which is composed of the leg and the foot, which form an angle ⁇ between them.
  • the aim of the present invention is to provide a shoe to be worn when performing sports or amateur cycling, capable of overcoming the above described problems that affect the background art.
  • a specific object of the invention is to provide a cycling shoe that allows to maximize the efficiency of the force applied by the cyclist to the cycling vehicle, especially to the pedals, completely eliminating or substantially reducing the factors that constitute a waste of energy consumption.
  • an object of the invention is to provide a cycling shoe that eliminates or drastically reduces the energy consumption traditionally expended by the muscles of the leg, considered as part of the lower articulation comprised between the knee and the ankle, with particular reference to the calf muscles.

  • the device according to the invention may be provided advantageously with means for temporary disengagement of the leg from the quarter-like portion, so as to utilize the possibility to rotate the ankle in particular circumstances, for example when traveling along a long downhill stretch, in which it can be necessary to use one's legs in order to optimize the balance of the system, this operation being more important, in this context, than optimization of the application of the pushing force generated by said cyclist.
  • any quick-coupling and uncoupling device particularly if it is easy to access and operate, can therefore be used as a complement to, or as a replacement of, the fastening means or the disengagement means illustrated here by way of example.

  • the present invention achieves the intended aim and objects.
  • the described device in each of its embodiments, prevents the rotation of the foot about the ankle joint on the plane of the circular motion of the propulsion mechanism of the cycling vehicle, keeping substantially unchanged the angle formed by the foot and by the leg of the cyclist during the pedaling stroke and eliminating the calf from the set of muscles involved actively in performing the pedaling stroke.
  • a wearable device as described above benefits from having a shape and/or being constituted by materials whose rigidity is such as to absorb, without detectable deformation, the forces that tend to flex it and, by flexing it, to modify the angle formed by the foot and the leg.
