Bicycle seatpost assembly

#Field of the Invention

#The present invention relates to a bicycle actuation structure and a bicycle seatpost assembly.

#Discussion of the Background

#A more complete appreciation of the invention and many of the attendant advantages thereof will be readily obtained as the same becomes better understood by reference to the following detailed description when considered in connection with the accompanying drawings.

#FIG. 1 is a perspective view of a bicycle seatpost assembly in accordance with a first embodiment.

#FIG. 2 is a cross-sectional view of the bicycle seatpost assembly illustrated in FIG. 1.

#The embodiment(s) will now be described with reference to the accompanying drawings, wherein like reference numerals designate corresponding or identical elements throughout the various drawings.

#Referring initially to FIG. 1, a bicycle seatpost assembly 10 in accordance with a first embodiment comprises a first tube 12 and a second tube 14. The second tube 14 is mounted to the first tube 12 to be retracted and extended relative to the first tube 12 in a telescopic direction D1. The first tube 12 is detachably attached to a seat tube 1A of a frame 1. The bicycle seatpost assembly 10 comprises a mounting structure 15 configured to fixedly mount a bicycle saddle (not shown) to the second tube 14. The mounting structure 15 is attached to an upper end of the second tube 14.

#In the present application, the following directional terms “forward”, “rearward”, “left”, “right”, “upward” and “downward” as well as any other similar directional textus refer to those directions which are determined on the basis of the rider who sits on the bicycle saddle (not shown) of a bicycle with facing a bicycle handlebar (not shown). Accordingly, these terms, as utilized to describe the bicycle seatpost assembly 10, should be interpreted relative to a bicycle equipped with the bicycle seatpost assembly 10 as used in an upright riding position on a horizontal surface.
