Definitions

  • the invention relates to a bicycle apparatus, and more particularly to a bicycle apparatus that is transformable between a recumbent bicycle conformation and a conventional safety bicycle conformation. It is immediately appreciated that the invention allows the bicycle rider to choose between either conformation in order to access a variety of bicycle riding terrain that would be inaccessible by either a nontransformable safety bicycle or a nontransformable recumbent bicycle. Additionally, the invention allows the bicycle rider to choose between the invention's two conformations in order to choose a position that is more comfortable for the bicycle rider. "Safety bicycle” is a term that denotes bicycles that allow the bicycle rider to ride the bicycle in an equestrian or upright position.
  • Safety bicycles typically possess a structural frame commonly known as either a diamond frame or an "A-frame.” Safety bicycles are commonly called road bicycles or touring bicycles. Safety bicycles also include the category of bicycles typically known as mountain bicycles or mountain bikes. Bicycle riders may ride safety bicycles over a variety of terrain conditions, including paved surfaces and unpaved trails through the woods or other natural areas. Safety bicycles often possess structural modifications that allow the bicycle rider to encounter a specific terrain condition. For example, safety bicycles modified for usage as a mountain bicycle often possess shock absorbing means, allowing the bicycle rider to comfortably navigate over uneven surfaces. The pedals of a safety bicycle are usually located between the bicycle tires.
  • Recumbent bicycles are bicycles configured in such a way that the plane running through the recumbent bicycle rider's hips and feet is parallel with the plane of the ground. Recumbent bicycles are well-known in the art. Recumbent bicycles are ideally suited for level terrain conditions, and the recumbent bicycle rider may achieve significant speeds and travel for substantial distances by exerting considerably less physical effort than that which would be required if the bicycle rider were riding a safety bicycle over the same terrain. The pedals of the recumbent bicycle are usually located above the front tire of the bicycle. Recumbent bicycles are difficult to ride over unpaved surfaces, over terrain with frequent changes in slope, or over the off-road terrain typically frequented by mountain bicycle riders.
  • the present invention addresses an unmet need for a bicycle apparatus that allows the bicycle rider to transform the physical conformation of a bicycle so that the bicycle rider can successfully and most efficiently ride over a variety of terrain than could be accomplished only by a recumbent bicycle or only by a safety bicycle. Additionally, the present invention allows the bicycle rider to choose either of the two conformations of the bicycle in order to best suit the bicycle rider's comfort needs.
  • the invention relates to a transformable bicycle apparatus that is transformable between a recumbent bicycle conformation and a conventional safety bicycle conformation.
  • An object of the invention is to provide a recumbent bicycle that is improved so that the bicycle rider can transform the conformation of the recumbent bicycle into a safety bicycle conformation.
  • Another object of the invention is to provide a safety bicycle that is improved so that the bicycle rider can transform the conformation of the safety bicycle into a recumbent bicycle conformation.
  • An advantage of the invention is that it allows the bicycle rider to efficiently and comfortably travel over a greater variety of terrain than would be possible with only a safety bicycle or only a recumbent bicycle.
  • Another advantage of the invention is that it allows the bicycle rider to choose between either a safety bicycle conformation or a recumbent bicycle conformation depending upon the comfort needs of the bicycle rider.

  • the apparatus of the present invention 10 is centered about a skeletal bar frame generally indicated at 1.
  • the frame comprises two crossbars 4, 4' that are connected at their ends and run together in a parallel manner. Although the two crossbars 4, 4' are connected at their ends, the crossbars do not touch together along their length, creating an aperture parallel to the length of the crossbars.
  • a rearwardly descending bar 5 connects to the frontward-facing ends of the crossbars 4, 4'.
  • the end of rearwardly descending bar 5 opposite crossbars 4, 4' connects to a dual-pronged fork 6.
  • the portion of the fork 6 opposite the prongs connects to the rearwardly descending bar 5.
  • the two prongs of fork 6 are adapted to receive rear tire 3.
  • rear tire 3 is a tire possessing a 26 inch diameter, but tires of other diameters could be utilized in the invention without departing from the scope and spirit of the invention.
  • the space between the prongs of fork 6 and the space between the attached prongs of double- ended fork 7 will allow rear tire 3 to rotate in this space.
  • the prongs at the end of double- ended fork 7 opposite to fork 6 connect to crossbars 4, 4'.
  • a threaded bar bolt 64 extends from the right side of cylinder 8 and from the left side of cylinder 8 such that the axis of each threaded bar bolt 64 is perpendicularly oriented to the axis of the frame 1 of bicycle 10.
  • the bicycle 10 includes an adjustable seat 11 for the bicycle rider.
  • the bicycle seat system 11 includes a seat back 12 so that the bicycle rider may ride the bicycle 10 when it is transformed into the recumbent position.
  • Adjustable seat 11 possesses any of the height adjustment means known in the art such that the height of the seat 11 may be raised or lowered depending upon the preferences of the bicycle rider and the conformation of the bicycle 10.
  • the seat post 13 of the adjustable seat 11 passes through the open portions of the bicycle frame 1 created by the open areas of upward facing portion of double ended fork 7 and crossbars 4, 4'. Additionally, the distance of the adjustable seat 11 from the steering means 50 may be adjusted.

  • the front chain roller 20 is located a few inches rearward of the threaded bar bolt 64.
  • the rear chain roller 21 is located rearward of double-ended fork 7.
