Definitions
- the invention relates to a folding bicycle having a first frame member carrying a first wheel and a pedal drive, and a second frame member carrying a second wheel driven by the pedal drive, wherein the first frame member and the second frame member are interconnected by a pivotal connection by which the second wheel fixed to the second frame part is pivotable in a direction of the first wheel directed about the pedal axis, and with a fender associated with the second wheel, according to the preamble of claim 1.
- a frame part in the course of folding a frame part is usually pivoted about a pivot axis which is oriented substantially parallel to the pedal axis, in a directed about the pedal axis pivotal movement in the direction of the first wheel.
- the pivot axis will be slightly inclined to the pedal axle, so that the two wheels can overlap laterally in the folded state and the bike occupies even less space in the folded state.
- the fender of the rear wheel which is arranged in the unfolded and thus mobile state of the bicycle above the rear wheel, is moved in a conventional manner with the pivotable frame part. Upon pivoting of the rear wheel about the pedal axle, the fender thereby assumes a position in which it comes to rest below the rear wheel. The fender thus prevents the bicycle can be pushed in the folded state, since the rear wheel can not roll on the ground. When folded, such bicycles must therefore be worn. However, this is highly uncomfortable.
- the object underlying the invention is to eliminate the disadvantages of the prior art and to provide a folding bike, which can be easily transported even in the folded state.
- a folding bike should also be characterized by a simple construction.
- Claim 1 relates to a folding bicycle with a first frame part, which carries a first wheel and a pedal drive, and a second frame part, the one of the pedal drive driven second wheel carries, wherein the first frame part and the second frame part are interconnected by a pivotal connection by which the second frame mounted on the second wheel is pivotable in a direction of the pedal axis pivoting movement in the direction of the first wheel, and with a second wheel associated fender.
- the fender is formed from a first fender part and a second fender part, wherein the first fender part is fixed to the second frame part and the second fender part is movably mounted relative to the first fender part.
- This division of the fender allows those parts of the fender, which would prevent rolling of the rear wheel in the folded state, are pivoted to another position in which they do not hinder the rolling of the rear wheel. In this way, a much more comfortable way to transport such a bicycle results.
- the relative mobility of the second fender part can be realized in particular by the relative movement of the fender parts is coupled to the folding operation, so in the course of Einklappvorganges and the relative movement of the fender parts is completed.
- the second fender part is pivotally connected to the first frame part via a first holder, and via a second holder hingedly connected to the second frame.
- the first holder may be hinged to the second fender part in the region of its end facing the first fender part.
- first frame part and the second frame part thus form together with the first and second holder a four-bar linkage for the second fender part, so that during the entire pivoting process of the two frame parts one always clearly defined position of the second fender partly results.
- such a construction is characterized by high stability.
- the two-part construction of the fender allows movement of the second fender part independently of the first fender part, so that the second fender part can be brought in the folded state of the bicycle, in particular in a position in which it does not affect a rolling of its associated wheel. This results in a much more comfortable transportation of such a bicycle.
- the first part of the fender which by folding without getting into a rolling unperturbable position, remains attached to the second frame part in a position fixed relative to the second frame part.
- the first frame part and the second frame part at a coupling point are connectable to each other, wherein the first holder is hinged in the region of the coupling point on the first frame part.
- the coupling point is that area of the bicycle in which the slightest relative movements between the first and the second frame part occur during driving. Since in the unfolded state of the bicycle facing end portions of the fender parts are preferably loosely overlapping each other, an undesirable noise at the fender can be avoided by reducing the relative movements.
- the coupling point is designed as a magnetic coupling.
- the magnetic coupling has the advantage that it exerts a strong coupling force under tensile and compressive loads, but can be relatively easily solved with shear loads.
- the coupling point can now be carried out so that in the mobile state of the bicycle according to the invention, the driver's own weight as well as driving-related shocks essentially act as tensile and compressive loads on the magnetic coupling, which thus prevents unintentional pivoting of the two frame parts. If the bike is to be folded, the magnetic coupling, however, can be solved manually by a shearing motion comparatively easy.
- the inventively provided relative movement between the two fender parts is preferably carried out simultaneously with the pivoting of the second frame part, so that it depends on the Einklappvorgang itself.
- these two processes are carried out independently of each other, for example by the second fender part is movable even before the folding process and therefore independent of this relative to the first fender part in a position in which he folded the two wheels in the folded Condition of the bike is not affected.
- the former design offers the advantage that, apart from the folding process itself, no separate action or actuation on the part of the user with regard to the mudguard is required.
- Fig. 5 shows the bicycle of FIG. 1 in the fully retracted position
- Fig. 6 shows the bicycle in perspective view and shortly after the beginning of the Einklappvorganges.
- Fig. 1 shows a folding bicycle 10 with a first frame part 1, which carries a first wheel 11 and a pedal drive 9, and a second frame part 2, which carries a driven by the pedal drive 9 in a conventional manner via a chain drive 8 second wheel 12.
- the first wheel 11 is the front wheel and the second wheel 12 is the rear wheel of the bicycle 10.
- the first (front) frame part 1 and the second (rear) frame part 2 are interconnected by a pivotal connection 4 by which the second frame part 2 with the second wheel 12 carried by it is pivotable towards the first wheel 11 via the underside of the bicycle 10 ,
- the position of the pivot axis of Swivel joint 4 may coincide with the pedal axis A, but in the embodiment shown it is arranged slightly offset from the pedal axis A. In both cases, however, attached to the second frame part 2 second wheel 12 is pivotable in a directed about the stationary pedal axis A pivotal movement in the direction of the first wheel 11.
- the pivot axis of the pivot connection 4 may be substantially parallel to the pedal axis A or slightly, be inclined by about 15 ° to the pedal axis A.
- FIGS. 2 to 4 each show different pivoting positions of the second frame part 2 in the course of the folding process.
- FIG. 6 shows a perspective view of the pivoting position according to FIG. 2.
- the first cream enteil 1 and the second frame part 2 at a coupling point 13 which is spaced from the pivotal connection 4, connectable to each other.
- the coupling point 13 forms on the one hand a stop for the second frame part 2 and thus limits the Ausklappière, and on the other hand also provides a releasable frictional connection between the first cream enteil 1 and the second cream enteil 2 ago.
- the coupling point 13 is designed as a magnetic coupling.
- the bicycle 10 further comprises a handlebar with a handlebar and a seat bar with a seat. These are mounted on the first frame part 1 in each case via a releasable lock 5. By loosening the lock 5a, the perch is telescopically inserted into the first frame part 1, and by releasing the lock 5b, the handlebar is telescopically inserted into the first frame part 1.
- the second wheel 12 has a fender 3, which is formed from a first fender part 3a and a second fender part 3b.
- the first fender part 3a is at least partially facing the first wheel 11 and thus closer to the first wheel 11 than the second fender part 3b.
- the first fender part 3a is in this case on the second frame part 2 in a position fixed relative to the second frame part 2 attached.
- the second fender part 3b is arranged in the unfolded and therefore ready to drive state of the bicycle 10 of FIG. 1 above the second wheel 12 and mounted relative to the first fender part 3a movable.
- the second fender part 3b is pivotally connected to the first frame part 1 via a first holder 6.
- the first holder 6 is hinged on the one hand to the second fender part 3b in the region of its end portion facing the first fender part 3a, and on the other hand hinged to the first frame part 1 in the region of the coupling point 13.
- the first holder 6 can, as can be seen in FIG. 6, be formed from two substantially parallel holding rods, which surround a portion of the first frame part 1 and / or a portion of the second frame part 2.
- the second fender part 3b is also attached to the second frame part 2 further. This attachment takes place via a second holder 7, which is articulated to the second fender part 3b and the second frame part 2 (see, for example, FIG. 4).
- the second holder 7 can also be formed from two essentially parallel holding rods which engage around the second wheel 12.
- the first frame part 1 and the second frame part 2 thus form, together with the first holder 6 and the second holder 7, a four-bar linkage for the second wing part 3b.
- the axes of this four-bar linkage are substantially parallel to each other.
- the second fender part 3b has been brought into a position in which it does not hinder the rolling of the second wheel 12 on a ground.
- the bicycle 10 can thus be easily transported rolling in its folded and not per se ready state shown in FIG. 5.
- the invention thus provides a folding bike that can be easily transported even in the folded state.
