Abstract

A hub assembly is provided for a human-powered vehicle. The hub assembly includes a hub axle, a hub body, a cable and a cable protector. The hub axle has a first axial end and a second axial end. The hub body is rotatably mounted on the hub axle to rotate around a rotational center axis of the hub assembly. The cable has a first portion disposed inside of the hub assembly and a second portion disposed outside of the hub assembly. The cable protector is movably arranged between a first position and a second position. The second portion of the cable extends along the rotational center axis where the cable protector is in the first position. The second portion of the cable being at least partly restrained in an angled position with respect to the rotational center axis where the cable protector is in the second position.

First claim

What is claimed is:

1 . A hub assembly for a human-powered vehicle, the hub assembly comprising:
a hub axle having a first axial end and a second axial end; a hub body rotatably mounted on the hub axle to rotate around a rotational center axis of the hub assembly; a cable having a first portion disposed inside of the hub assembly and a second portion disposed outside of the hub assembly; and a cable protector movably arranged with respect to the hub axle between a first position and a second position, the second portion of the cable extending along the rotational center axis where the cable protector is in the first position, and the second portion of the cable at least partly being restrained in an angled position with respect to the rotational center axis where the cable protector is in the second position.

2 . The hub assembly according to claim 1 , wherein
the cable protector is pivotally mounted with respect to the hub axle between the first position and the second position.

3 . The hub assembly according to claim 2 , wherein
the cable protector has a pivot axis that extends in a twisted or intersecting relationship with respect to the rotational center axis of the hub body.

4 . The hub assembly according to claim 1 , wherein
the cable protector is a wire rod.

5 . The hub assembly according to claim 1 , wherein
the first portion of the cable is at least partly extending along the rotational center axis.

6 . The hub assembly according to claim 5 , wherein
the wire rod has a first end disposed on a first side of a reference plane and a second end disposed on a second side of the reference plane in a case where the reference plane entirely contains the rotational center axis and is perpendicular to a pivot axis of the cable protector.

7 . The hub assembly according to claim 1 , further comprising
a rotation restriction part configured to be disposed between the hub axle and a frame of the human-powered vehicle so that rotation of the hub axle relative to the frame is restricted.

8 . The hub assembly according to claim 7 , wherein
the rotation restriction part is detachably attached to the hub axle.

9 . The hub assembly according to claim 7 , wherein
the rotation restriction part includes a cable guide structure configured to guide the second portion of the cable in an angled direction with respect to the rotational center axis.

10 . The hub assembly according to claim 9 , wherein
the cable guide structure is further configured to guide the cable in a radial direction of the hub axle.

11 . The hub assembly according to claim 9 , wherein
the cable guide structure includes a groove configured to guide the cable.

12 . The hub assembly according to claim 11 , wherein
the cable protector is attached inside the groove of the cable guide structure.

13 . The hub assembly according to claim 11 , wherein
the cable protector includes a cable restricting portion that is wider than a width of the cable.

14 . The hub assembly according to claim 7 , wherein
the rotation restriction part includes a recess, and the cable protector is releasably retained in the recess where the cable protector is in the second position.

15 . The hub assembly according to claim 14 , wherein
the cable protector is resiliently deformed as the cable protector moved into and out of the recess.

16 . The hub assembly according to claim 1 , further comprising
an electric component non-rotatably disposed with respect to the hub axle, and wherein the cable is an electric cable electrically connected to the electric component.

17 . The hub assembly according to claim 16 , wherein
the electric component including an electric circuit board, and the electric cable is electrically connected to the electric circuit board.

18 . The hub assembly according to claim 1 , further comprising
an electric power generator provided to the hub body, and configured to generate electric power by rotation of the hub body.

19 . The hub assembly according to claim 1 , further comprising
a sprocket support structure rotatably disposed around the rotational center axis to transmit a driving force to the hub body while rotating in a driving rotational direction around the rotational center axis.

20 . A hub assembly for a human-powered vehicle, the hub assembly comprising:
a hub axle having a first axial end and a second axial end; a hub body rotatably mounted on the hub axle to rotate around a rotational center axis of the hub assembly; a cable having a first portion disposed inside of the hub assembly and a second portion disposed outside of the hub assembly; and a cable protector being a wire rod and disposed on the hub axle, and the second portion of the cable at least partly being restrained in an angled position with respect to the rotational center axis.
