Definitions

  • This invention relates to motorized-tricycles for transporting a user and his belongings over terrain and more particularly to golf tricycles.
  • carts are generally unusable as the weight of the cart causes the vehicle's tires to become lodged into the course.
  • trolleys/caddies while typically less expensive and lighter than golf carts are not an ideal alternative to carts as they must be manually towed around the course by a user.
  • the use of such trolleys/caddies can therefore be tiring for some individuals.
  • the use of such trolleys/caddies also does not expedite a user's playing time, since users are still required to walk.
  • Such trolleys are also not useful for individuals who are unable to walk from hole to hole. For such individuals, a golf cart or some alternative means of transportation is required.
  • tricycles One possible alternative to the golf cart and trolleys/caddies is a tricycle.
  • Existing tricycles are difficult and tiring for some individuals to utilize as users must manually operate the foot pedals in order to move from one location to the next.
  • Most existing tricycles also do not have any mechanism for towing and those that do, are physically draining to operate as they are not power-assisted.
  • the wheels of these tricycles also make travel over various terrains such as distressed, water-logged courses, difficult.
  • Tricycles are typically not designed for collapsing into a less bulky arrangement for storage and vehicular transport. Tricycles are also not easily transported by a vehicle using the currently available mounting devices for vehicles.
  • the current invention relates to a motorized tricycle which allows users, once seated on the tricycle, to move from one location to the next by manually pedalling the tricycle or by engaging the tricycle's motor.
  • the present invention is directed to a means of transportation for travelling over various types of terrains, including those which are distressed or water-logged.
  • the invention is a tricycle having a frame with a front and a rear portion, a semi-recumbent seat attached to the frame, three wheels rotatably mounted to the frame, a drive assembly for moving the wheels, a steering assembly connected to the frame and a mounting assembly for carrying objects such as golf bags.
  • the drive assembly includes an electric and manual power source.
  • the steering assembly includes a steering handle which is detachably and pivotally mounted to the front portion of the frame and connected to the front wheel such that a user of the tricycle may steer the vehicle by moving the handle in a horizontal direction.
  • the steering handle is also attached to the drive assembly and in particular the electric power source or motor of the assembly such that the user of the tricycle can engage or disengage the motor using the steering handle. Users may therefore manually tow the tricycle using the steering handle with or without the assistance of the tricycle's motor.
  • the invention is the tricycle described in the paragraph above and including a permanent and non-removable steering handle bar located under the seat, allowing the rider to control the vehicle totally with manually operated hand controls.
  • the hand control includes dual hand levered breaking assemblies, a variable power DC electric rheostat throttle control, a forward and reverse switch and an on and off ignition switch.
  • the steering handle bar also houses a rotating gear shift assembly linked by a wire control to the internal hub transmission.
  • the invention is a tricycle having a frame with a front and a rear portion, a seat attached to the frame, three pairs of wheels rotatably attached to the frame, a drive assembly, a steering assembly connected to the frame, a mounting assembly and a load spreading system.
  • One wheel is rotatably attached to the front portion of the frame and two pairs of identically sized and horizontally aligned wheels are attached to the rear portion of the frame, with one pair disposed on either side of the seat.
  • the drive assembly includes an electric and manual power source.
  • the steering assembly includes an auxiliary handle which is detachably and pivotally mounted to the front portion of the frame and which when attached, is connected to the front wheel such that a user of the tricycle may steer the vehicle by moving the handle in a horizontal direction.
  • the steering handle is also attached to the drive assembly and in particular, the electric power source or motor of the assembly such that the user of the tricycle can engage or disengage the motor using the steering handle.
  • the load spreading system includes two pair of identically sized and horizontally aligned wheels.
  • An inflatable bladder surrounds the circumference of each pair of wheels. Once inflated, the bladder creates a unitary wheel having a larger contact surface area than that of each individual wheel.
  • the weight of the tricycle is distributed over a larger surface area. By distributing the tricycle's weight over a larger area, the tricycle is able to travel more efficiently over distressed and/or water-logged terrain.
  • the load spreading system includes a pair of identically sized and horizontally aligned wheels, where each wheel rim is surrounded by a wide, non-inflatable airless tire having flexible edges that depress to increase the footprint as the wheel rotates past bottom dead center.
  • the wheel rim and hub motor design incorporates two separate pieces, allowing the rim to be removed or changed by simply removing a secure locking ring. The locking ring is held in place by a number of threaded screws.
  • the wide load-spreading tire rim assembly is interchangeable with a pneumatic tire rim assembly, which can be used on regular paved surfaces.
  • the invention is the tricycle mentioned above having either the steering assembly alone or having both the steering assembly and the load spreading system as discussed above, and which is capable of being collapsed and arranged into a transportation mode capable of being mounted to a transportation frame apparatus or placed into storage.
  • the transportation frame apparatus is capable of being secured to the tow/draw bar socket attached to the vehicle.
