Problems solved by technology

Thus, a problem with a typical bicycle front derailleur is that the angular orientation of the chain guard is fixed relative to the base member.
Specifically, since the angular orientation of the chain guard is fixed relative to the base member for most bicycle front derailleurs, the bicycle front derailleur cannot be mounted in the optimal orientation for all current bicycle frames. Install

[0053] Referring now to Figures 13 and 14, a modified horizontal angle adjusting mechanism 52' according to the second embodiment will be described. In view of the similarity between the first and second embodiments, parts of the second embodiment that are identical to parts of the first embodiment will be given the same reference numerals as parts of the first embodiment. Also, the description of the parts of the second embodiment that are the same as those of the first embodiment may be omitted for the sake of brevity. Parts of the second embodiment that are different from those of the first embodiment will be indicated by symbols (').

[0054] The horizontal angle adjusting mechanism 52' of the second embodiment is different from the first embodiment in that: the adjusting plate 46 of the first embodiment is replaced by an improved adjusting plate 46', and the first embodiment is replaced by an improved inner cover plate 80' The inner cover plate 80 of the example and the ...

Abstract

A front chain-poke device of a bicycle comprises a base component, a movable component and a leading-chain device with an angle-adjusting plate component; wherein, the base component is designed to be connected with one part of the bicycle; the movable component is provided with a first bearing side and a second bearing side, and the first bearing side is connected to the base component while the second bearing side is isolated from the first bearing side; the movable component is designed to facilitate the second bearing side to move between a retracting position and an extending position relatively to the base component; the angle-adjusting plate component is connected to the second bearing side so as to make movement together with the second bearing side; the leading-chain device comprises a chain cover which operates and connects the angle-adjusting plate component so as to selectively adjust the angle orientation of the chain cover relatively to the angle-adjusting plate component.

Description

technical field [0001] The present invention generally relates to a bicycle front derailleur with an angle adjustment device. More particularly, the present invention relates to a bicycle front derailleur with an adjustment mechanism that provides angular adjustment of a chain guard of the front derailleur relative to the bicycle frame. Background technique [0002] Cycling is becoming an increasingly popular form of recreation as well as a mode of transportation. Moreover, cycling has become a very popular competitive sport among both amateurs and professionals. Whether the bicycle is used for recreation, transportation or competition, the bicycle industry is constantly improving the various components of the bicycle. One component that has been extensively redesigned is the bicycle front derailleur. [0003] Generally speaking, the front derailleur is usually fixed to the seat tube or bottom bracket of the bicycle frame. Basically, a front derailleur includes: a base (...
