- the invention provides a foldable bicycle comprising a frame formed of two arms, one of the arms having an end hingedly connected to a steering rod having at the lower end a first wheel, the other arm being connected to a second wheel, said two arms being mounted articulated with respect to each other to move from a so-called unfolded position in which said arms are spaced from one another the first and second wheels being arranged in the same plane (P), in a folded storage position in which said arms are brought closer to one another so that the first and second wheels overlap, and locking means arranged to allow selective locking of said arms in an intermediate position between the unfolded position and the folded storage position.
- the presence of selective locking means can modulate the folding position of the bicycle according to the needs and expectations of the user by providing intermediate locks between the unfolded position and the folded storage position.
- the locking means are arranged to allow the locking of the arms in a folded intermediate position in which the first and second wheels are held in the plane (P).
- the locking means comprise a locking plate having two toothed portions adapted to cooperate respectively with complementary toothed portions formed on two locking pads, each locking pad being carried respectively by one of the arms, the plate locking device being movable between a locked state in which the toothed portions of said plate cooperate with the corresponding toothed portions of the locking pads and an unlocked state in which the tooth portions of said plate are disengaged from those of the locking pads.
- the two toothed portions of the locking plate have a different tooth profile.
- the locking plate is connected to an actuating plate by means of two connecting pins, each axis being slidably mounted through one of the arms.
- the locking means comprises elastic return means arranged between one of the arms at least and the actuating plate.
- each arm is coupled to one another by a set of teeth for meshing of one arm by the other arm.
- each arm has an abutment surface arranged to define the unfolded position of said arms.
- the arms are connected to one another by a connecting piece carrying the locking means.
- the bicycle comprises a seat tube connected to the locking means by means of an articulated link to allow the passage of a position of use of the saddle to a storage position of the saddle, the connecting rod being arranged with the locking plate so that the transition to the locked state of said plate also blocks the saddle in position.
- FIG. 4 and 5 show a diagrammatic view respectively front and section along the axis IV-IV of the bicycle locking means when the latter is unfolded position;
- Figure 6 and 7 show a schematic view of the locking means respectively of Figures 4 and 5 when they are in an unlocked state
- FIG. 11 shows a schematic detail view of a bicycle according to an alternative embodiment.
- a bicycle 1 can take several positions.
- the bicycle 1 can take an unfolded position corresponding to a position of use ( Figure 1), a folded position said storage ( Figure 3) and a folded position for rolling Bicycle 1 (folded position called rolling) ( Figure 2).
- the bicycle 1 according to the invention comprises a frame 2 carrying the saddle 3 and the crankset 4, said frame 2 being formed of two arms 5, 6 respectively connecting the front part and the rear part of the bicycle 1.
- front arm 5" the arm connecting the front portion of the bicycle
- rear arm 6 the arm connecting the rear portion of the bicycle.
- the front arm 5 is rotatably articulated by its front end 50 to a pivoting steering rod 7, said rod having at the lower end 70 a first wheel 8 (front wheel of the bicycle 1) and at the end upper 71 a handlebar 9.
- the rear arm 6 is connected by its rear end 60 to a second wheel 10 (rear wheel of the bicycle 1) connected to the pedal 4 by a transmission means 11.
- the arms 5, 6 of the frame are mounted articulated relative to each other to move from a so-called unfolded position ( Figure 1) wherein said arms are spaced apart from one another so as to be disposed substantially in the extension of one another to a so-called folded position ( Figures 2 and 3) wherein said arms are close to one another.
- Figures 2 and 3 the arms are arranged relative to each other so that the front and rear wheels are arranged in the same plane P when the bicycle 1 is in the folded position rolling and slightly overlap when the bicycle 1 is in the folded storage position.
- the plane P corresponding to the plane in which the front and rear wheels are arranged when the bicycle is unfolded.
- the front and rear arms 5, 6 are connected to one another by a connecting piece 12 comprising a support plate 13, each arm 5, 6 being mounted on the support plate 13 through a pivot axis 15, 16.
- a connecting piece 12 comprising a support plate 13, each arm 5, 6 being mounted on the support plate 13 through a pivot axis 15, 16.
- the arm before 5 is hingedly mounted on the support plate 13 by the pivot axis 15 while the rear arm 6 is hingedly mounted on the support plate 13 by the pivot axis 16.
- the arms 5, 6 are mounted articulated at opposite ends at the front ends 50 and rear 60 of the arms 5 and 6 previously defined. These ends will be called later "joining ends 51, 61.
- the connecting piece 12 further comprises locking means arranged to allow selective locking of said arms 5, 6 in an intermediate position between the unfolded position and the folded storage position, one of the advantageous intermediate positions being the folded position of the bearing illustrated in Figure 2.
- the locking means comprise a locking plate 17 (or clutch), in the illustrated example of elongated shape, having a front portion 170 and a rear portion 171 respectively toothed.
- the "front” and “rear” parts of the locking plate are defined according to their position relative to the bicycle.
- the toothed front and rear portions 170, 171 of the locking plate 17 are arranged to cooperate respectively with complementary toothed portions 180, 190 formed on two locking shoes 18, 19 (or clutch shoe), each shoe of locking being carried by one of the arms 5, 6.
- the locking plate 17 is arranged to be movable between a position in which the toothed portions 170, 171 of the plate of latch 17 cooperate with the corresponding toothed portions 180, 190 of the locking shoes 18, 19 (referred to as locked state) as illustrated in FIGS. 4 and 5 and a position in which the toothed portions of the plate are disengaged from those locking shoes 18, 19 (this is called unlocked state or disengaged plate) as shown in Figures 6 and 7.
- front and rear toothed portions 170, 171 of the locking plate 17 having different tooth profiles.
- Such a configuration has the advantage of allowing the position to be modulated angular of the arms 5, 6 relative to each other and therefore the position of the wheels relative to each other.
- the locking plate has in the lower part a clearance 172 to allow the passage of the locking pads once the arms 5, 6 in the folded position (clearance shown in Figure 4 and Figures 8 to 10).
- the locking plate 17 is connected to an actuating plate 20 disposed opposite the support plate 13 via two connecting pins 25, 26, each axis being slidably mounted through one of the pivot axes 15, 16 of the arms 5, 6.
- the transition from the locked state to the unlocked state will be carried out by exerting a thrust on the actuating plate 20 towards the locking plate, the latter driving the locking plate 17 and with it the release of the locking pads 18, 19 ( Figure 6 and 7).
- an elastic return means 14 is disposed between the support plate 13 and the actuating plate 20 so as to return the locking plate 17 between the locking pads 17, 18, in its seat 21, during the release of the actuating plate 20.
- the two arms 5, 6 are coupled to each other by a set of teeth 52, 62 formed at their junction end 51, 61.
- the toothing 52 of the front arm 5 is shaped to meshing the toothing 62 of the rear arm 62 during the transition from the unfolded state to a folded state and vice versa.
- each arm 5, 6 has, at its junction end 51, 61, an abutment surface 53, 63 arranged to establish the unfolded position of said arms 5, 6.
- the passage from the unfolded position of the bicycle to the folded position is carried out as follows.
- Figures 8 to 10 show the meshing of the arms 5, 6 during their passage from the unfolded position in which they are distant (FIG. 8) to their folded storage position in which they are substantially parallel to each other (FIG. by the intermediate folded rolling position in which they have a determined angular spacing (Figure 9).
- the thrust exerted on the actuating plate 20 is stopped.
- the connecting pins 25, 26 effect, under the action of the elastic return means 14, a translation movement in the pivot axes 15, 16 in the direction of the actuating plate 20, until that the locking plate 17 enters the space defined between the locking shoes 18, 19 to come to block the arms 5, 6, and thus the front wheels 8 and rear 10, in the desired folded position (the folded storage position or an intermediate folded position).
- the seat tube 30 is connected to the locking means via an articulated rod 22 arranged to allow the passage of a position of use of the seat 3 to a position of storage of the saddle 3 in addition to the folding of the frame 2 at the approach of the front and rear arms 5, 6.
- the rod is arranged with the locking plate so that the transition to the locked state of said plate also locks the saddle in the desired position.
- Figure 11 illustrates the possible arrangement of the locking means on a frame when it comprises two symmetrical branches, each branch being formed of two arms similar to those described above.
