Definitions

  • the present invention relates to a foldable bicycle, which is capable of shortening a folding time, a size after folding, and a foldable bicycle which is easy to carry.
  • An object of the present invention is to provide a folding bicycle which is small in shape close to a shape and can be transported even if it is rolled like a car.
  • the four points at the intersection and the tip forming the X-shaped frame are all used as rotation axes, and one of the two points attached to the front wheel side head lug, the upper one is It is attached to a driving ring that moves up and down the center of the head rug.
  • the driving ring moves down. Since the rotating ring attached around the axis of the driving ring also moves downward, the connecting rod connecting the rotating ring and the handle also folds the left and right handles downward.
  • the lower one point is attached to one end of an I-type frame that rotates around a fulcrum at the center of the seat tube, and is attached to the other end of the I-type frame. Is connected to the saddle support Connecting rod is attached. Therefore, when the X-shaped frame is folded, the lower point on the sheet tube side of the X-shaped frame moves upward, so that the type 1 frame rotates and the other end of the I-type frame moves downward. As you move, move the saddle down. When the saddle is moved downward by the connection of the frames as described above, the I-type frame, the X-type frame, and the left and right handles are simultaneously and simultaneously folded. To make it easier to restore your bike from its folded state to its original state,
  • FIG. 1 is a side view showing the foldable bicycle of the present invention before being folded
  • FIG. 2 is a front view thereof
  • FIG. 3 is a side view showing the folded state of the foldable bicycle
  • FIG. 4 is a front view showing the folded state.
  • the bicycle frame is composed of the X-type frame 1 and the I-type frame 2, so the X-type frame has four points a, b, c, and d.
  • point b is attached to the lower end of the head lug 3
  • point c is the end of the upper frame 4 projecting from the top of the seat tube 5
  • point d Is attached to one end of I-frame 2.
  • the midpoint q of the I-shaped frame 2 is attached to the fulcrum at the center of the seat tube 5, and the X-shaped frame 1
  • the intersection point P and points a, b, c, d, and q can be folded because they are all rotatable structures.
  • the left and right handles 15 are bent right and left at the upper end of the handle post 6, and are connected to a rotating cylinder 9 that rotates around the axis of the driving ring 8 and a handle connecting rod 10.
  • the left and right handles # 5 are opened and closed by moving the training ring 8 up and down.
  • the other point g of the I-type frame 2 and the saddle support 7 are connected by a saddle connecting rod 11 and the lock of the handle opening 'cut 1' and the saddle opening i is released.
  • the folding bicycle according to the present invention is extremely easy to fold and restore, and can be turned into a trunk just by putting a cover on the bicycle. On the floor S, it can be lifted and carried by hand as if holding a trunk.Because of its small size, it is inconspicuous even if you bring it in a train or bus. It is very convenient '. It can be used as a bicycle that you can easily bring wherever you go

Abstract

L'invention concerne un cadre de bicyclette comprenant une structure en forme de X pivotante (1) et une structure en forme de I (2) se rejoignant au point central (p), un anneau coulissant verticalement mobile (8) et un anneau rotatif (9) étant fixés à un montant de guidon (3). Les deux extrémités de la structure en forme de X côté roue avant sont respectivement fixées rotatives à l'extrémité inférieure du montant de guidon et à l'anneau coulissant, les deux extrémités côté roue arrière étant respectivement fixées à l'extrémité en pointe d'un organe supérieur (4) et à une extrémité de la structure en forme de I. L'anneau rotatif est raccordé à des barres de poignées droite et gauche (15) par une barre de raccordement (10), l'autre extrémité de la structure en forme de I étant reliée à un montant de selle (7) par une barre de raccordement (11). Lorsque la selle est poussée vers le bas, ce dispositif permet de déplacer la structure en forme de I, la structure en forme de X, l'anneau coulissant et les barres de poignées de manière conjointe, d'où un pliage simultané.
