Definitions

  • the present invention relates to a foldable exercise bicycle which is provided with a folding frame in order to reduce the bicycle size.
  • a drawback of these prior bicycles is that they have a comparatively large size since the construction of she several elements of the bicycle does not provide the possibility of folding the bicycle frame to a compact stored condition.
  • the document US-A-3 578 800 discloses a foldable exercise bicycle having substantially the features of the pre-characterizing portion of the main claim.
  • the aim of the present invention is to overcome the above mentioned drawbacks by providing a compact foldable exercise bicycle including a bicycle folding frame which can be easily and quickly folded in order to provide the bicycle with a very compact size in a stored condition thereof.
  • a main object of the present invention is to provide such a bicycle construction which can be folded so as to reduce both its length and its height.
  • Another object of the present invention is to provide such an exercise bicycle which can be easily transported on a pair of wheels and which is very reliable and safe in operation.
  • Yet another object of the present invention is to provide such an exercise bicycle which can be easily made starting from easily available elements and materials and which, moreover, is very competitive from a mere economic standpoint.
  • the compact foldable exercise bicycle which has been generally indicated at the reference number 1, comprises a bicycle frame which includes a central body 2 which is advantageously constituted by two adjoining metal plates 3 which are connected to a saddle upright 4, advantageously made as a square cross-section tubular element, and a front bearing element, also constituted by square cross-section tubular elements.
  • the upright 4 and front downward leg support 5 are rigidly connected to the bicycle frame and project from said frame at two opposite sides and are advantageously parallel to one another.
  • the front leg support 5 ends at the bottom thereof with a front cross element 6 which, preferably, is provided with wheels 7.
  • a handle upright To the central body 2 there is articulated, at the front portion thereof, a handle upright, indicated at 10, whereas to the rear end portion of the central body 2 there is pivoted a rear leg support 11.
  • both the upright 10 and the rear leg support 11 are made of square cross-section tubular elements.
  • rear bearing element ends with a rear cross element 12 which, at the end portions thereof, is provided with bearing pads 13.
  • the handle upright 10 is interconnected with the rear leg support, through a tie-rod 20, which is articulated between an intermediate position of the rear leg support 11 and the bottom end of the upright 10 so as to cause, as the frame is folded, the rear leg support 11 and the upright 10 to simultaneously turn, thereby causing the upright 10 to move toward the upright 4 and the rear leg support 11 to move toward the front downward leg support 5.
  • the driving gear of the room bicycle comprise pedal assemblies 40, to which there is connected a central pulley 41, and which are rotatably supported with respect to the central body 2.
  • a driving or transmission belt 45 which further extends on a roller 46 coaxial and rigid with a flywheel 47.
  • a braking strip element 50 On the periphery of the flywheel 27 there is entrained a braking strip element 50, which has a fixed point at its rear end portion and, at its front end portion, is connected through the interposition of a spring 51 and a flexible tie-rod, provided for adjusting the friction in order to allow the pedalling force to be adjusted.
  • flywheel 47 is supported by plates 55 which are rigid with the front bearing element 5.
  • the bicycle further comprises a protecting casing generally indicated at the reference number 70.
  • the bicycle saddle 41 is connected by means of a telescopic column 72 which allows the size of the bicycle to be further reduced, in its not use condition, since the telescopic column 72 can be fully withdrawn within the upright 4.
  • the handlebar 80 is connected, by means of a telescopic handlebar column 81, to the handlebar upright 10 so as to provide a desired height adjustment as well as to further reduce the bicycle size in its folded or collapsed condition.
