Abstract

A bicycle derailleur comprises a base member, a chain guide, a first link, and a wire guide. The base member is configured to be coupled to a bicycle frame. The chain guide is configured to guide a bicycle chain. The first link is configured to couple the chain guide to the base member so that the chain guide is movable relative to the base member between a retracted position and an extended position. The wire guide includes only one wire guiding portion configured to guide an inner wire of a control cable which is in at least one of a top pull arrangement and a bottom pull arrangement. The wire guide is a separate member from the first link and configured to be attached to the first link.

First claim

What is claimed is:

1 . A bicycle derailleur comprising:
a base member configured to be coupled to a bicycle frame; a chain guide configured to guide a bicycle chain; a first link configured to couple the chain guide to the base member so that the chain guide is movable relative to the base member between a retracted position and an extended position; and a wire guide including only one wire guiding portion configured to guide an inner wire of a control cable which is in at least one of a top pull arrangement and a bottom pull arrangement, the wire guide being a separate member from the first link and configured to be attached to the first link.

2 . The bicycle derailleur according to claim 1 , wherein
the wire guiding portion is configured to guide the inner wire of the control cable which is in one of the top pull arrangement and the bottom pull arrangement.

3 . The bicycle derailleur according to claim 2 , further comprising:
an additional wire guide including an additional wire guiding portion configured to guide the inner wire of the control cable which is in another of the top pull arrangement and the bottom pull arrangement, wherein the additional wire guide is a separate member from the first link and the wire guide, and the additional wire guide is configured to be attached to the first link.

4 . The bicycle derailleur according to claim 3 , wherein
the wire guide and the additional wire guide are configured to be detachably attached to the first link to be replaceable with each other.

5 . The bicycle derailleur according to claim 1 , wherein
the wire guide is configured to be detachably attached to the first link to be replaceable with another wire guide.

6 . The bicycle derailleur according to claim 1 , wherein
the wire guide is configured to be attached to the first link so that the wire guide is disposed at one of a first orientation and a second orientation relative to the first link, the second orientation is different from the first orientation, the wire guiding portion is configured to guide the inner wire of the control cable which is in one of the top pull arrangement and the bottom pull arrangement in a first state where the wire guide is disposed at the first orientation relative to the first link, and the wire guiding portion is configured to guide the inner wire of the control cable which is in another of the top pull arrangement and the bottom pull arrangement in a second state where the wire guide is disposed at the second orientation relative to the first link.

7 . The bicycle derailleur according to claim 6 , wherein
the first link includes
a first end configured to be pivotally coupled to the base member about a first pivot axis, and
a second end configured to be pivotally coupled to the chain guide about a second pivot axis, and
when viewed from an axial direction of the first pivot axis, the wire guiding portion in the first state of the wire guide is disposed on an opposite side of the wire guiding portion in the second state of the wire guide relative to a reference line extending between the first end and the second end.

8 . The bicycle derailleur according to claim 7 , wherein
the second orientation is an orientation where the wire guide is turned approximately 180 degree about a rotational axis parallel to the first pivot axis relative to the first link from the first orientation.

9 . The bicycle derailleur according to claim 6 , wherein
the wire guide includes a first side and a second side opposite to the first side, and the second orientation is an orientation where the wire guide is turned over so that positions of the first side and the second side are replaced relative to the first link.

10 . The bicycle derailleur according to claim 1 , wherein
the wire guiding portion includes a guide hole through which the inner wire is to extend.

11 . The bicycle derailleur according to claim 1 , wherein
the wire guiding portion includes a guide groove through which the inner wire is to extend.

12 . A bicycle derailleur comprising:
a base member configured to be coupled to a bicycle frame; a chain guide configured to guide a bicycle chain; a first link configured to couple the chain guide to the base member so that the chain guide is movable relative to the base member between a retracted position and an extended position; and a wire guide which is a separate member from the first link, the wire guide being configured to be attached to the first link so that the wire guide is disposed at one of a first orientation and a second orientation relative to the first link, the second orientation being different from the first orientation, the wire guide including
a top-pull wire guiding portion configured to guide an inner wire of a control cable in a first state where the wire guide is at the first orientation relative to the first link, and
a bottom-pull wire guiding portion configured to guide the inner wire of the control cable in a second state where the wire guide is at the second orientation relative to the first link, the bottom-pull wire guiding portion being different from the top-pull wire guiding portion.

13 . The bicycle derailleur according to claim 12 , wherein
the first link includes
a first end configured to be pivotally coupled to the base member about a first pivot axis, and
a second end configured to be pivotally coupled to the chain guide about a second pivot axis,
when viewed from an axial direction of the first pivot axis, the top-pull wire guiding portion and the bottom-pull wire guiding portion are disposed on a first wire side relative to a reference line extending between the first end and the second end in the first state, when viewed from the axial direction of the first pivot axis, the top-pull wire guiding portion and the bottom-pull wire guiding portion are disposed on a second wire side relative to the reference line in the second state, and the second wire side is opposite to the first wire side relative to the reference line.

14 . The bicycle derailleur according to claim 12 , wherein
the wire guide includes a first side and a second side opposite to the first side, and the second orientation is an orientation where the wire guide is turned over so that positions of the first side and the second side are replaced relative to the first link.

15 . The bicycle derailleur according to claim 12 , wherein
at least one of the top-pull wire guiding portion and the bottom-pull wire guiding portion includes a guide hole through which the inner wire is to extend.

16 . The bicycle derailleur according to claim 12 , wherein
at least one of the top-pull wire guiding portion and the bottom-pull wire guiding portion includes a guide groove through which the inner wire is to extend.
