Definitions

  • the present patent application for industrial invention relates to a road bicycle simulator.
  • a typical simulator is composed of an elongated, narrow base on which a bicycle is mounted in perfectly vertical position, in such a way that the rear wheel of the bicycle interferes with a closed pair of rolls supported by the same base, in orthogonal position with respect to the longitudinal axis of the bicycle.
  • at least one of the rolls is subject to a braking action that can be adjusted by the user to grade the pedalling effort.
  • a bicycle mounted on a traditional simulator is not capable of exactly generating all the sensations that are typically felt by a biker when cycling on the road.
  • the bicycle frame is not subject to a "natural" stress, that is to say a stress comparable with ordinary road cycling. More precisely, the user of a traditional simulator is not capable of reproducing the classical pendular movement from side to side suffered by the bicycle on the road, especially when the biker is cycling uphill and is therefore forced to stand on the pedals for a more energetic pedal thrust.
  • An additional drawback of traditional simulators - which contributes to increase the user's dissatisfaction - consists in the impossibility to put the bicycle mounted on the simulator in upward tilted position, similar to the position of the bicycle when riding a road uphill.
  • the user of a traditional simulator must renounce one of the most exciting and desired feeling, that is to say the sensation of cycling on a challenging mountain road.
  • the specific purpose of the present invention is to devise a static simulator that is finally able to give the bicycle mounted on the simulator the same positions and movements that are typical of road cycling.
  • the new simulator of the invention is able to give the bicycle the possibility to reproduce the pendular movement from side to side that is produced when the biker stands on the pedals, and at the same time raise the front fork of the bicycle upwards in tilted position, as it exactly occurs when riding a road uphill.
  • the bicycle is finally capable of creating sensations that are equal to road cycling, with a "natural" stress being imposed on the bicycle frame.
  • the present invention is based on the fact that the simulator of the invention ensures a special elastic "pendular" connection to the front fork of the bicycle.
  • the bicycle of the invention is able to maintain a perfectly perpendicular position with respect to the ground while in idle state or while the user sits on the seat and simulates smooth, constant pedalling, such as on a flat road.
  • the bicycle is alternatively tilted on both sides - starting from the front - according to the stress imposed by the user, and spontaneously recovers the position perpendicular to the ground as soon as the said stress is finished.
  • the rear of the bicycle mounted on the simulator of the invention is completely free of restrictions; it being only provided that the wheel rests on a pair of rolls with horizontal axis that usually permit or oppose rotation during pedalling.
  • the aforementioned alternate oscillation of the front corresponds to a similar inclination of the bicycle frame and to a lateral swerve of the rear wheel over the pair of rolls with horizontal axis.
  • the simulator of the invention is provided with two idler wheels with vertical axis that act as stop limits, being situated in intermediate position between the rolls with horizontal axis and in the proximity of the lateral ends of the same rolls.
  • the function of the wheels is to prevent the rear wheel from uncontrollably sliding on the side, in case of excessive swerve, and losing contact with the pair of rolls with horizontal axis.
  • the distance between the two wheels can be adjusted by the user as desired; in this way the user is able to determine the lateral swerve permitted for the rear of the bicycle, also in view of the bicycle size.
  • the system designed to provide the elastic "pendular" connection of the front fork is of adjustable type; this guarantees that the resistance of the same fork to lateral inclination is adjusted as desired according to the user's physical strength or weight.
  • the device that provides the "pendular" connection is subject to the action of suitable elastic elements, such as springs, shock- absorbers or similar elements; the aforementioned regulation of resistance to the lateral inclination of the fork is provided by means of modular elastic elements (adjusted as desired by the user) or with the possibility to mount the most appropriate elastic elements according to the specific needs of each user on the said device.
  • suitable elastic elements such as springs, shock- absorbers or similar elements
  • the simulator of the invention permits to adjust the effort made on the pedals, regardless of using the gear provided on the bicycle.
  • the simulator of the invention is able to coordinate the adjustment of the effort made on the pedals with the capability of giving the bicycle an uphill position, with the front of the bicycle raised from the ground with respect to the rear.
  • a training session on the simulator of the invention is never repetitive or monotonous, and is extremely efficacious from the physiological viewpoint, since it forces the user's legs to work in the same position and with the same effort produced when cycling on a mixed road.
  • the simulator of the invention can be advantageously used in combination with any type of bicycles (mountain bikes, city bikes and race bikes), regardless of the bicycle size.
  • simulator of the invention Another remarkable characteristic of the simulator of the invention is represented by high efficacy and safety of contact with the ground, which is largely due to the width of the support base. Because of this, the simulator of the invention maintains perfect stability, including in case of energetic alternative oscillations of the bicycle mounted on the simulator, and therefore guarantees efficacious training without any type of risk.

  • the rotation shaft (38) of the roll (4a) is formed of a circular jacket (104) of ferrous material and of opposite covers (204) fitted to the said jacket (104) with peripheral screws, the same covers being provided with central bushes (304) that, with the interposition of bearings, support the axis (38), which is in turn supported, with the interposition of low-friction means, also by the ending supports (39) fitted to the frame members (1a) of the base (1 ) of the simulator, as explained below.
  • Four circular pole pieces (40) of any suitable ferromagnetic material, for instance ferrous material, are radially fitted with the same mutual angular distance, with a tapered end in contact with the shaft (38) in such a way that they can be welded mutually and to the shaft.
  • the radial pattern formed by the pole pieces (40) is turned at the ends (140) in such a way that they are concentric with respect to the internal surface of the jacket (104) at a short distance from it.
  • the four pole pieces (40) are fitted with corresponding coils (41) with electrical winding to form the necessary magnetic fields that will be preferably contrary for the axially aligned poles, in such a way that one north and one south pole are generated.
  • the coils (41) are held in place by means of elastic rings (42) housed in corresponding annular recesses of the pole pieces (40).
  • the magnetic fields produced by the coils and relevant pole pieces are closed through the jacket (104) and reduce the rotation of the roll (4a), while the shaft (38) is constrained to the frame (1 ).
  • the electrical conductors (43) that are necessary to power the coils (41) pass through an axial cavity of the shaft (38) and through the cavity of one of the frame members (1 a) that are used as raceways, with the same conductors (43) that reach the switchboard (26) for connection to the power means contained in it (see figs. 7 and 3, 3a).
  • the shaft (38) is supported by the supports (39) since the said shaft is constrained to the frame (1) by means of a transducer (44) able to supply an electrical signal proportional to the effort used to make the pole pieces (40) rotate by the jacket (104) of the roll (4a) turned by the rear wheel (R) of the bicycle, that is to say an electrical signal proportional to the braking imposed on the same jacket (104), in such a way that the switchboard (26) receives a retroaction signal for the correct powering of the coils (41).

  • the transducer (44) comprises a crank (144) splined at one end of the shaft (38) that, either directly or by means of levers, cooperates with a load cell (244) fitted to a frame member (1a), from which an electrical cable (344) reaches the switchboard (26) through the cavity of the frame member.
  • the covers (204) of the roll (4a) are provided with multiple holes (48) positioned on an ideal circumference concentric to the same covers, used to provide good air circulation inside the roll, being the said circulation forced by a small electric fan (45) fitted on the shaft (38) and powered by the same small cable as the coils (41 ), or by a fan, not shown, joined to one of the covers (204) of the roll (4a).
  • the said holes (48) are also used to measure the rotation speed of the roll (4a), for instance through a proximity sensor or any other means (46) fitted to the frame (1 ), whose electrical cable (146) is brought to the switchboard (26) through the internal cavity of one frame member (1a). It is understood that the description does not contain constructive details for the switchboard (26) and the panel (Q), being of known type for those expert of the art.
  • a first constructive variant may refer to the shock-absorbing and return mode of the rocker arm (10).
  • the rocker arm (10) is no longer connected with the traditional shock-absorbers (11 ), but to a pair of special oil-pressure cylinders that communicate through a suitable circuit with a shut-off valve.
  • the said valve adjusts the oil flow that is alternatively received from either one of the cylinders, according to the stress transmitted by the rocker arm (10); evidently, by changing the passage section of the oil flow with the said valve, the said oil-pressure cylinders can be hardened or softened as desired. More specifically, in this case, each of the forks (10a) provided in lower position on the rocker arm (10) is pivoted to the upper end of the stem of the piston inserted into the oil-pressure cylinder.
  • this operating principle is produced in cyclic, alternate mode between the two oil-pressure cylinders until the fork (F) of the bicycle (B) transmits a stress to the rocker arm (10).
  • the braking system of the rear roll (4a) may be obtained according to an alternative mode; to that end, a brake-shoe with felt coating may be used to interfere with the external surface of the roll (4a) by means of the pressure established from time to time by the user.
  • the braking force of the brake-shoe - which could be advantageously pivoted to one of the longitudinal rods (1a) of the base (1) - may be remotely adjusted by means of a flexible wire, using the same knob mounted in front of the handlebar of the bicycle (B) on top of the tubular vertical rod (14).
  • the fork (F) of the bicycle (B) may be fixed according to an alternative mode, in which the holes provided along the arms (12) that protrude from the rocker arm (10) are not threaded and are capable of cooperating with stop means, such as the means used to fix the hub of the wheel to the fork when using a racing bicycle for road cycling.
