Definitions

  • the present invention refers in general to the field of thrusting devices for cycles, and in particular to a motored wheel supplied by batteries that can be applied to cycles used as help when moving.
  • the system is applied preferably, but not exclusively, for aiding drivers of wheelchairs for handicapped people, field in which there are no currently known systems of this type adapted to alleviate the driver's efforts in moving the wheelchair.
  • Object of the present invention is solving the above prior art problems, providing a system with motored wheel that can be applied to cycles, particularly to wheelchairs, that decreases or zeroes the driver's fatigue, exerting a thrusting torque at least equal to about 10 Nm at a speed of about 3.5 km/h.
  • a further object of the present invention is providing a system of the above-described type that can be applied on folding wheelchairs, leaving their practical use unaltered: the motored wheel is autonomous in its operation and does not impair the wheelchair manoeuvrability.
  • a first preferred embodiment of the system of the invention is shown.
  • reference 1 is a push-button
  • 2 is a container for batteries and electronics for system operation
  • 3 is a series of fixed supports for the system
  • 4 is a ratio-motor
  • 5 is a device for disconnecting the ratio-motor 4
  • 6 is the motored wheel
  • 7 are securing brackets
  • 8 is a shaft for supporting the ratio-motor 4
  • 9 is a thrust regulator of the motored wheel 6 downwards
  • 10 is a descent regulator of the motored wheel 6
  • 11 is a key switch for actuating the system.
  • the system of the invention operates depending on the principle of clutch gearing. After having inserted the key into the turning-on switch 1 and after having pressed the push-button 1 placed on the handle 21 of the wheelchair 14 (not described in detail since it is of known configuration and operation), the wheelchair 14 itself must be pushed by the driver up to a basic speed (about 1.5 km/h) in order to be able to actuate the motor 4.
  • Object of such features is performing a startup that is adjusted by the driver, in addition to avoiding that the push-button 1 is unintentionally pressed, generating thereby a dangerous and undesired movement of the wheelchair 14.
  • a torque limiter of the motor 4 has been devised: when the foreseen limit is exceeded, the motor 4 is turned off to be turned on again after a greater thrust is applied by the driver.
  • the support 3 of the motored wheel 6 is fixed to the chassis 16 of the wheelchair 14 with specific connections 7, and has a hook-shaped system 5 in order to keep fixed the system parts that are able to be disassembled and to exclude the motored wheel 6 when it is assembled and is not used.
  • the wheels 6, in this case, are inserted in the fixed part with a simple lateral thrust, and are composed of several parts: the axial ratio-motor 4, the level regulator 10, the pressure regulator 9 towards the ground, a shock absorber and a gripping handle (not shown in this first embodiment).
  • the motored wheel is placed on the center of the rear wheels 18 of the wheelchair 14.
  • the system contains batteries (not shown) and on its external side it has connectors 20 for supplying the motor 4, the battery-charger and the push-button 1. There are further provided (not shown) a fuse, two signalling warning lights, quick connections to the support for removal and a gripping handle. Finally, the support of the battery 2 is secured to the chassis 16 of the wheelchair 14 through specific connections 3.
  • the above-described system is thereby composed of five main parts: two fixed parts and three mobile parts.
  • the two fixed parts, the motor support and the battery support remain assembled onto the wheelchair and do not limit its flexibility; the three mobile parts, motor and battery, can be easily disassembled, thereby realising the objects that the system had been designed to obtain.
  • a battery-charger with which it is possible to recharge the battery itself at home.
  • the thrust point 30 is herein pointed out, that shows the main feature for which the manoeuvrability of the wheelchair 14 is not impaired by the presence of the motored wheel 6, though being the wheel 6 fixed along the running direction (arrow A) of the wheelchair 14 itself.
  • a second preferred embodiment of the system of the invention is shown.
  • reference 1 is a push-button
  • 2 is a container for batteries and electronics for system operation
  • 3 is a series of fixed supports for the system
  • 4 is a ratio-motor
  • 5 is a device for disconnecting the ratio-motor 4
  • 6 is the motored wheel
  • 7 are securing brackets
  • 8 is a shaft for supporting the ratio-motor 4
  • 9 is a thrust self-adjusting spring that also adjusts the descent of the motored wheel 6 downwards
  • 11 is a key switch for actuating the system.
  • the second embodiment contains a self-adjusting spring 9 that performs the same functions as of the regulator 9 and the regulator 10 of the first embodiment; moreover, the second embodiments provides for the use of a gripping handle 10' and a pedal 12 for inserting the ratio-motor 4: these parts help the driver to connect the ratio-motor 4 and operate the system of the invention without having to bend himself downwards in order to reach the system controls, as in the first embodiment.
  • the simple pressure of the pedal 12 enabled by the gripping handle 10' allows the ratio-motor 4 to be easily and immediately actuated, thereby allowing the driver to remain erect.
