Definitions

  • the invention relates to a bicycle frame containing a main tube with a head tube in the front and with a bottom bracket down on an extended end. To the frame is fixed a rear fork by the holder. The holder is situated above the bottom bracket. The rear fork is fixed as immovably or by swing way.
  • the bicycle frame contains a main tube with a head tube in the front and with a bottom bracket down on an extended end.
  • a rear fork by the holder.
  • the holder is situated above the bottom bracket.
  • the rear fork is fixed as immovably or by swing way.
  • the holder is formed from a tube and it is joined to the adjacent wall of the main tube and eventually also with a saddle tube.
  • the holder is formed from a tube and it is joined to the adjacent wall of the main tube and eventually also with a saddle tube.
  • the holder with the main tube and also eventually with the saddle tube joined by a weld.
  • fastening bar goes through the holder at least partly out of the main tube, it is possibile to weld the fastening bar with the holder and with the main tube altogether. This connection eliminates deformations, which could be to induce some stressing cracks.
  • FIG.l is the whole view of the frame (in longitudinal section) in the version of an immovable rear fork.
  • FIG.2 is the view with a swing rear fork, whereas the FIG.3 shows the longitudinal section through the bottom part of the frame before putting the bottom bracket with fastening bar into this section.
  • Bottom bracket with fastening bar is on FIG.4 and FIG.5 describes the frame, after the bottom bracket with the fastening bar is putted into its place of the frame and it is welded together.
  • a bicycle frame R which contains a main tube 1 with a head tube 12 and a saddle tube 17. Down at an extended end VL of the main tube 1 a bottom bracket 13 is fixed. To the frame R is by the holder UL situated above the bottom bracket B, fixed a rear fork V. By realization according FIG.l is rear fork V fixed immovably and by realization according FIG.2 is rear fork V fixed in swing way by means of a joint 2. Between the main tube I and the fork V is integrated a spring 3. The holder 14 goes through the adjacent wall Ia of the main tube I and touches the opposite wall Ib. With the main tube I at the adjacent wall Ia is the holder 14 joined by a weld.
  • the opposite wall Ib is in the place of touching the holder 14 provided by a hole 16, in which is the holder 14 welded together with the main tube 1. From the bottom bracket H extends upwards a fastening bar 15 and it goes through the holder 14- The fastening bar 15 goes through the holder 14 partly out of the main tube 1. This position allows the fastening bar 15 to be welded with the holder 14 and with the main tube 1 alltogether.
