Embodiment Construction

[0088] In FIG. 1 , a bicycle, in particular a racing bicycle, is denoted 1 . The cycle 1 comprises a seat 2 connected to a frame 3 of the cycle 1 via a seat post 10 according to the invention. The cycle 1 also includes a bottom bracket 4 and a handle 5, both of known form.

[0089] For example figure 2 As shown more clearly in , the seat post 10 includes a tubular element 11 and a pair of jaws 13, at least a part of the longitudinal extension of the tubular element 11 is adapted to be telescopically inserted into a suitable tubular seat 12, and the tubular seat 12 is arranged on the bicycle 1 In the bracket 3 ( FIG. 1 ), the jaws 13 are integral with the tubular element 11 and are adapted to grip the seat 2 to connect the seat 2 to the tubular element 11 . In particular, the jaws 13 grip the straight portion 14 of the support rod 15 of the seat 2 . Generally speaking, the frame of the seat 2 includes two bars 15 arranged side by side, and the straight portion 14 of each bar...

Abstract

A seat post (10) for a bicycle, comprises a tubular element (11) adapted to support a seat (2) of a bicycle (1) and grasping means (130, 230) of a portion (14) of frame (15) of said seat (2), adapted to be selectively activated / deactivated to prevent / allow a translation movement of the seat (2) with respect to said tubular element (1) along a predetermined direction. The grasping means (130, 230) comprise at least one first abutment element (137'') and can be coupled with said tubular element (11) in a first operative coupling configuration in which said at least one first abutment element (137'') defines a first translation limit position of the seat (2) with respect to the tubular element (11) in a first way of said predetermined direction.; The grasping means (130, 230) also comprise at least one second abutment element (137') that defines, when the grasping means (130, 230) are coupled with said tubular element (11) in a second operative coupling configuration, at least one second translation limit position of the seat (2) with respect to the tubular element (11) in said first way of said predetermined direction, said at least one second translation limit position being translated with respect to said first translation limit position along said first way of said predetermined direction.

Description

technical field [0001] The invention relates to a bicycle seat post. More specifically, the present invention relates to an adjustable seat post for a racing bicycle. Background technique [0002] In this document and in the appended claims, references to "bicycle seat post" are used to mean the part of a bicycle that supports the seat on the bicycle frame. Specifically, "adjustable seatpost" refers to a seatpost that allows adjustment of the position of the seat relative to the pedals of the bicycle. [0003] In the field of bicycles, especially racing bicycles, the use of adjustable seatposts is quite common. The ideal seat position is one that allows most of the rider's front legs to be bent at 90 degrees when the pedals are aligned horizontally. [0004] Of course, the ideal position of the seat will vary according to the size of the rider, especially the length of the legs. This ideal position can be achieved by moving the seat vertically relative to a vertical refe...
