Abstract
What is disclosed is a bicycle frame (1) comprising a seat tube (4) in which a saddle pillar (2) for a saddle is at least partially held, wherein the saddle pillar (2) or the main tube (12) thereof is adapted for translatory movement and height-adjustment relative to the bicycle frame (1). In this case, a rotation prevention device and a locking device, in particular a seat device, are fastened on the seat tube (4). Both securing devices act between the seat tube (4) and the main tube (12) in a form-fitting manner. In this case, the device for securing against rotation engages permanently in the main tube and the latching device can engage in, and can be disengaged from, the main tube.
Claims16
A bicycle frame comprising:
- a seat tube wherein a main tube of a saddle pillar of a saddle may be inserted by at least portions thereof, wherein the main tube is adapted for translatory movement and height-adjustability relative to the seat tube;
- the seat tube further comprising a form-fit rotation prevention means fastened to the seat tube;
- a switchable locking device for the main tube fastened to the seat tube;
- wherein
- the saddle pillar comprises a pipe integral with the saddle which is adapted for translatory movement and height-adjustability relative to the main tube, and which is inserted in an upper end portion of the main tube and adapted to be clamped thereto;
- wherein
- the form-fit rotation prevention means prevents rotation of the saddle when a height of the saddle is adjusted;
- wherein
- the form-fit rotation prevention means and the switchable locking device are combined in one fixation device by at least portions thereof;
- and wherein
- the fixation device comprises an elastic member supported on the fixation device and applies a lifting force to the main tube.
A method for assembling a bicycle frame, comprising the steps of
- providing the bicycle frame including:
- a seat tube wherein a main tube of a saddle pillar of a saddle may be inserted by at least portions thereof, the main tube being adapted for translatory movement and height-adjustable relative to the seat tube, comprising a form-fit rotation prevention means fastened to the seat tube and a switchable locking device for the main tube fastened to the seat tube, wherein
- the saddle pillar comprises a pipe integral with the saddle which is adapted for translatory movement and height-adjustable relative to the main tube, and which is inserted in an upper end portion of the main tube and adapted to be clamped thereto;
- and
- wherein the form-fit rotation prevention means prevents rotation of the saddle when a height of the saddle is adjusted;
- and wherein the form-fit rotation prevention means and the switchable locking device are combined in one fixation device by at least portions thereof;
- inserting a fixation device in a main tube of a saddle pillar;
- producing a recess at a seat tube of the bicycle frame;
- inserting the main tube in the seat tube;
- fastening a base plate on or in the recess from the outside;
- and
- screw-fastening the base plate and the fixation device.
