Definitions
- Two-wheeled vehicle with frame which can be folded up by actuation control and transmission means
- the present invention relates to a two-wheeled vehicle provided with a frame which can be folded up by means of associated means for control of the actuation and transmission.
- the established technology consists in the manufacture of a frame of the traditional type formed by tubes which are made of various materials and welded together. These frames, although they have managed to achieve a very high ratio in terms of their own weight against the carrying weight, are such, however, that neither their weight nor their overall dimensions can be further reduced to a significant degree.
- a frame for two-wheeled vehicles is also known from IT- 1,248,931 in the name of the same Proprietor, said frame consisting of a reticular structure forming functional sections such as the steering, the pedal - 2 -
- the technical problem which is posed, therefore, is that of providing a frame for two-wheeled vehicles such as bicycles, mopeds and the like, which is low-weight, functionally equivalent to a normal frame and can be folded up into its smallest size and opened out into its normal size in an automatic and repeatable manner without the need for co-ordination of the operations by the user.
- a further requirement is that the frame should be easy and inexpensive to produce industrially and to assemble.
- a foldable two-wheeled vehicle comprising a frame in which there is provided at least one central body, at least one group supporting the rear wheel, at least one group supporting the front wheel and at least one group for steering the front wheel, which are respectively hingeably joined to the said central body which comprises means for controlling and actuating the rotation of said groups around said central body, so as to close/open the frame from an open configuration suitable for use to a closed configuration suitable for transportation and vice versa.
- FIG. 1 shows a perspective view of a bicycle with a frame according to the invention in the condition where it is totally open, ready for normal use
- - Figure 2 shows a cross-section along a longitudinal plane of symmetry of the bicycle illustrated in Fig. 1
- - Figure 3 shows a cross-sectional view of the bicycle -3-
- FIG. 4 shows a cross-sectional view, similar to that of Fig. 2, with the frame fully folded.
- the frame for two-wheeled vehicles according to the invention is composed of a central body 10 formed by two parallel bars 11, the respective opposite ends of which are connected together in " the transverse direction by pins 13.
- Said pins 13 have also pivotably mounted on them corresponding gussets 12a and 12b, i.e. front gussets and rear gussets, respectively, which are arranged on opposite sides and on the outside of the said bars 11.
- a pair of struts P15 for connecting the section 10 to a steering bar 50 are also connected to the front gussets 12a.
- a further pair of struts P16 connects a group 60 forming the fork of the front wheel 61 to a lever 70 which is pivotably mounted between the bars 11 as described in detail further below.
- the end of said struts Pl ⁇ opposite to the end fastened to the front fork is designed to engage into a corresponding seat 13a of the pin 13 so as to cause locking thereof.
- the handlebar 51 is joined to one end 50a of the steering bar 50 by means of associated transverse pins, while the other end 50b of the steering bar is joined, by means of a pin 61, to the fork 60 of the wheel 61.
- the opposite ends of a tie-rod T56 are respectively pivotably mounted on the steering bar 50 and the fork 60, so as to connect the two parts.
- the fork 20 of the rear wheel 21 is pivotably mounted on the rear pin 13.
- Two struts P41 are also pivotably mounted on said gussets 12b, the saddle 42 being mounted on the top end of said struts by means of a pin 42a.
- the same pin 42a of the saddle also has pivotably mounted on it one end of a connecting rod 43, the other end of which is joined to a connecting-rod pin 43a, with which a tie-rod T41 connecting the saddle group to the bar 11 of the group 10 and a tie-rod T42 connecting the saddle group to the rear fork are also hinged; the strut P41 and the tie-rod T42 are connected together by a lever 100 for co-ordinating the relative movement.
- the rear fork 20 and the front fork 60 have, arranged between them, pairs of tie-rods T23 and T63 for supporting the pedal group 30 comprising a gear 31 from which the pedals 32 extend and which is rotatable by means of a bracket 33 about the rear pin 13, said gear 31 being connected to the pinion 22 of the rear wheel by means of a transmission 34 and a belt 35.
- the load-bearing structure of the bicycle is completed by further tie-rods T14 and T15 arranged between the central section 10 and the saddle group 40 and the steering group 50, respectively.
- the said lever 70 is arranged inside the central group 10 and rotates about a fixed pin 71 arranged transversely with respect to the two bars 11. Further pairs of rods are pivotably mounted on the opposite ends 70a and 70b of the lever 70, i.e.:
- the handle 200 is rotated so as to release the tie-rods T41 from the rear fork 20 and eliminate the locking force on the struts P16 which are now free to disengage from the pin 13 of the central group 10;
- control lever 70 is operated, causing it to rotate in an anti-clockwise direction about the pin 71;
- the lever 70 causes rotation also of all the rods L72, L73, L74, L76 which, reacting against the respective parts connected to them, cause closing of the frame into the configuration shown in Fig. 4.
- the pedals may be folded equally well at the start or at the end of the closing sequence so as to eliminate the associated transverse volume which is occupied.
- control means 70 for opening/closing thereof may be servo-assisted by corresponding means of the elastic or electromechanical type.
