Definitions

  • the invention relates to a bicycle frame with height-adjustable seat post according to the preamble of patent claim 1 and a method for its assembly.

  • To adjust the clamping is released, the saddle with the seat tube in height adjusted and the clamping actuated again.
  • a suitable adjustable seat post is for example from the
  • the active surfaces of the separating piston arrangement are designed such that the upwardly effective force component in the extension direction is greater than the force component acting in the retraction direction, so that the inner tube is prestressed in the extension direction.
  • the inner tube When the pressure fluid connection is open, the inner tube can then be pushed into the outer tube to change the saddle height, for example when driving downhill, by the weight of the driver, wherein pressure medium from the decreasing pressure chamber is displaced over the opened pressure medium connection in the increasing pressure chamber.
  • the determination of the seat post in a predetermined relative position is carried out by closing the pressure medium connection, so that the pressure medium exchange between the two filled with an incompressible medium pressure chambers is prevented.
  • the pressure chambers still associated with a type of air spring, which is formed by formed in the inner tube and / or in the outer tube air volumes.
  • DE 10 2009 010 170 A1 It has an outer tube and an inner tube displaceable therein, wherein a separating piston is arranged between the outer and inner tube, which delimits a positive space and a negative space.
  • a pressure medium connection between the positive space and the negative space can be closed by means of a closing element.
  • This closure member may be an elastomeric ring and may be configured to be in the closed position, i. with shut off fluid connection, inner tube and outer tube non-positively or positively connects with each other.
  • a disadvantage of such bicycle frame with adjustable seat post is that in addition to the seat tube of the frame, a recorded therein outer tube of the seat post and in turn received therein inner tube of the seat post are needed. This means a considerable weight and a small adjustment range of
  • the invention is based on the object to provide a bicycle frame with adjustable seat while driving seat post, in which a rotation of the seat post is prevented and its weight is reduced.
  • the bicycle frame according to the invention has a seat tube into which a main tube of a seat post is at least partially insertable, wherein the main tube relative to the seat tube is translationally movable and adjustable in height.
  • an anti-rotation device and a locking device - in particular support device - are attached to the seat tube. Both fuses act positively between the seat tube and the main pipe.
  • the anti-rotation has a permanent and the locking device a switchable engagement in the main pipe.
  • the locking device For holding or for supporting the seatpost in at least two different adjustment positions (eg uphill and downhill position), it is preferred if the locking device has a fixing pin substantially movably arranged transversely to an adjustment direction, and if the main pipe at least two spaced along its longitudinal axis has radial recesses into which the fixing pin can engage. It can also be provided significantly more than two radial recesses on the main pipe. This increases the fine gradation and / or the adjustment range of the height adjustment.
  • Radial passages are preferred as radial recesses on the main pipe.

  • the fixing pin is preferably movable out of the respective radial recess via a rotating device and / or via a pulling device and via a Bowden cable from an operating element of the link. This allows a cyclist to solve the detent quickly and easily and make the height adjustment.
  • the rotation can have a radially inwardly directed recess or groove in the main pipe, in the radially from the outside at least one frame-mounted sliding block is used.
  • the recess or groove may be formed in the hydroforming process and should have a length which corresponds at least to the adjustment height.
  • the anti-rotation device and the latching device are combined in a structural unit as a fixing device.
  • the fixing pin is held in the fixing device, and if the remote control has the arranged on the fixing pin outside the seat tube arranged rotary device for the fixing pin, which is movable via the Bowden cable from the control element of the handlebar.
  • the fixing pin is rotated and moved on the basis of a helical groove substantially transversely to the adjustment. A clamping of the fixing pin in the radial recess so we avoid. It is particularly space-saving if the fixing device is essentially received in the seat post, in particular in a main tube of the seat post. As a result, the fixing device is also mechanically protected against external influences.
  • the anti-rotation has a feather, which is inserted into a slot of the seat post - especially in a slot of its main pipe.
  • a length of the slot should correspond to at least a length of the adjustment.
  • this has a saddle-fixed tube, which is slidably inserted and thus adjustable in height in the upper end portion of the main tube and can be attached thereto by clamping.
  • an elastic element is supported or secured to the anti-rotation device or to the fixing device and acts on the seat post or its main tube with a lifting force. This can be reduced by loosening the fixing device and by loading the seat post or its main pipe saddle height. This is important e.g. when going downhill or in less sporty drivers before descending. By loosening the fixing device and by relieving the seat post or its main pipe saddle height can be increased. This is important e.g. when driving uphill or in less sporty drivers after the upgrade and after achieving a stable straight ahead.
  • a preferred development of the elastic element is a tension spring or a rubber band, which is or inside the seat post - especially in the interior of its main tube - is arranged. It is preferred if the tension spring or the rubber band between the fixing device or the rotation and the seat post - in particular its main pipe - is clamped and hung.
  • the elastic element may extend from the fixing device or the anti-rotation device to a lower end portion of the main pipe.
  • the elastic element extends upward, at its upper end portion a pliable pulling means is attached, which is guided over a deflection - in particular a deflection roller - and is fixed below the deflection on the main pipe.
  • Air spring which is arranged inside the seat post - in particular in the interior of its main tube.
  • the air spring has an outer tube and an inner tube which partially overlap and together define a pressure space, the inner tube being fixed to the fixing device, while the outer tube is directly or indirectly fixed to the seat post.
