Definitions

  • This invention relates to a bicycle of a changeable riding position.
  • a desired characteristic of the bicycle is that it can be folded or modified into as small as possible space, when being transported, for example, in a car or in a public service vehicle.
  • the bicycle according to the publication in question does not enable collapsing or modifying so that it could fit in a small space, for example, for transport or storage.
  • the front part of the main frame is articulated into a separate front frame, by means of which the height of the pedal crankset changes to the opposite direction when the height of the seat changes.
  • the aim of this invention is to eliminate above-mentioned disadvantages and to accomplish a bicycle which has good riding characteristics in all riding positions between the low and the high riding position, and which is possible to be modified for fitting into a small space for transport or storage.
  • the bicycle should be collapsible so that when it is partially collapsed it forms an armchair in which the cyclist may have a rest, for example, during travel.
  • the bicycle has an articulation with which the main frame is connected to the rear fork and the front frame, and these articulations may be adjusted independently from each other, whereby, by changing the angle between the main frame and the rear fork and the angle between the main frame and the front frame, one is able to steplessly form a desired riding position and desired riding characteristics.
  • the pedal crankset is fastened to the main frame, and the pedal crankset rises or lowers based on how the geometry of the bicycle is changed.
  • the pedal crankset rises upwards, and at the same time, the angle between the main frame and the front frame may be changed.
  • the axle spacing that is, the distance of the front wheel and the rear wheel from each other, either decreases or increases.
  • the backrest, the saddle and the handlebar are also articulated and further steplessly adjustable to a different position, whereby, when changing the geometry of the bicycle, they may be set as desired to the most suitable position for the cyclist.
  • the main frame has a busbar, with which the seat frame slides, into which the saddle and the backrest are articulated.
  • the seat frame being movable along the busbar, the distance of the saddle and the backrest from the pedal crankset is adjustable for cyclists of different heights.
  • the bicycle enables several different efficient and well-designed riding positions, and it is collapsible into a small space for transport. Because of the articulation, the geometry of the bicycle may be changed so that the riding position may be as desired between the riding position of a nearly lying recumbent and a high riding position.
  • the city-riding characteristics are achieved with an upright and high, short axle spacing, an upright steering angle and the centre of gravity thus being high.
  • the air resistance is achieved low and the riding characteristics directionally-stable with different speeds by lowering the riding position, extending the axle spacing and flattening the steering angle.
  • the frame articulation enables the collapsing of the bicycle into a small space, and it may be utilised as an adjustable armchair the backrest functioning as a support for the back and the saddle functioning as a seat.
  • the locking and the adjustment of the articulations is effected with locking beams and locking pins, screw adjusters, cable locking, pneumatic, hydraulic systems or equivalent structures.
  • FIG. 1 shows the bicycle and its components
  • Figure 2 shows the different riding positions of the bicycle, an upright city-riding position, a gently-reclining cruising position and a low road-riding position, and the most significant measure changes of the frame caused by two main articulations
  • Figure 3 shows the different articulations of the bicycle and the movements of the articulations
  • Figure 4 shows the collapsing of the bicycle
  • Figure 5 shows an alternative solution of a bicycle according to the invention.
  • FIG 1 shows the following main components of the bicycle:
  • saddle, 22. busbar in main frame with which busbar seat frame slides (with seat frame, the distance of saddle and backrest from pedal crankset may be adjusted suitable for cyclists of different sizes),
  • a handlebar 1 is fastened to a handlebar-stem inner part 2 which may move in the longitudinal direction inside a handlebar-stem casing part 3.
  • the handlebar-stem casing part 3 is fastened with an articulation 4 to a front fork 6, and the front fork 6 is able to rotate around a front frame 24.
  • the front frame 24 is fastened with an articulation 23 to a main frame 12 and is able to rotate because of the articulation 23 in regard to the main frame 12.
  • a seat frame 19, into which a saddle 21 is fastened, is able to move along a busbar 22 in the main frame, and a backrest 17 is fastened to the seat frame 19 with an articulation 18.
  • An articulation 16 which connects a rear fork 15 and the main frame 12, enables the rotation of the rear fork and the main frame in regard to each other. Forces are conveyed from a pedal crankset 9, which is fastened to the main frame 12, over the articulation 16 either with a drive chain, axle, belt or equivalent to a rear hub 14, and the drive chain or the axle or the belt may pass inside or outside of the main frame 12 and the rear fork 15, these being either tube-like, bar-like or equivalent casing-like or enclosed structures.
  • Figure 2 shows different riding positions of the bicycle, and the most significant measurement changes of the frame caused by the angular changes of the main rear articulation 16 and the main front articulation 23: the change of the pedal-crankset height (h1-h2), the change of the height of the saddle centre (H1-H2), the change of the axle spacing (L1-L2), and the change of the steering angle ( ⁇ 1 - ⁇ 2).
  • h1-h2 the pedal-crankset height
  • H1-H2 the change of the height of the saddle centre
  • L1-L2 the change of the axle spacing

  • the rear fork 15 is able to rotate in regard to the main frame by means of the articulation 16, and correspondingly, the front frame 24 is articulated to the main frame with the articulation 23.
  • the frame of the bicycle folds into a small size by means of a main front articulation 23, a main rear articulation 16, a backrest articulation 18, a stem articulation 4 which enable changing of riding position, and further a folding articulation 25 folding the front frame 24 transversely in regard to the drive direction.
  • the bicycle folds into a small size so that the front hub 7 and the rear hub 14 are side by side, which enables trailer-like pulling behind.
  • Figure 5 shows an alternative solution of a bicycle according to the invention, in which solution parallelogram-articulation is utilised.
  • linkage bar links rear fork and front frame to each other so that the angles of both change in a proper relation with regard to main frame
  • locking cylinder adjusts and locks the angle of front frame with regard to main frame, and also the angle of rear fork through linkage bar
  • the front frame 24 and the rear fork 15 are linked to each other with a linkage bar 27 which jointly with the main frame 12, the front frame 24 and the rear fork 15 forms a parallelogram.
  • a change of one angle changes a second angle in a desired relation.
  • the change of the angle of the front frame in regard to the main frame 12 changes the angle of the rear fork 15 in regard to the main frame 12, in a proper relation from the viewpoint of changing riding positions and riding characteristics.
  • the parallelogram solution decreases the number of separately adjustable settings in changing the riding position, when the articulations 23 and 16 are adjusted in a proper relation in regard to each other.
