As seen in FIGS. 5 and 7, the second locking member 44 is pivoted relative to the securing axle 23 about the second pivot axis PA2 from the unlocking orientation (the unlocking position P22) to the locking orientation (the intermediate position P23). At this time, the holding member 62 is moved relative to the securing axle 23 toward the second locking member 44 by the biasing force from the biasing element 64. Thus, the additional holding surface 69 comes into contact with the receiving surface 46 of the second locking member 44, allowing the second locking member 44 to be easily held in the locking orientation relative to the securing axle 23.
As seen in FIG. 5, the second locking member 44 is moved relative to the securing axle 23 in the movement direction D3 from the intermediate position P23 to the locking position P21. In this state, as seen in FIG. 2, the adjustment member 40 is rotated relative to the movable member 36 until the adjustment member 40 comes into contact with the first bicycle frame 3. The first locking member 32 is pivoted relative to the movable member 36 from the release position P12 to the securing position P11, moving the securing axle 23 relative to the movable member 36 in the first axial direction D11. Thus, the first bicycle frame 3, the hub axle 21, and the second bicycle frame 4 are sandwiched between the adjustment member 40 and the second locking member 44 in the axial direction D1. Since the procedure opposite to the above procedure applies to the detachment of the wheel securing assembly 12, it will not be described in detail here for the sake of brevity.
It is possible to obtain the following advantageous effects with the wheel securing assembly 12 and the bicycle wheel assembly 10.
(1) With the wheel securing assembly 12, the receiving surface 46 is positioned relative to the securing axle 23 to face in an axial direction D1 parallel to the center axis A1 in the locking orientation of the second locking member 44. The receiving surface 46 is configured to face in a direction that is different from the axial direction D1 in the unlocking orientation of the second locking member 44. Accordingly, it is possible to easily attach and detach the wheel securing assembly 12 to and from the bicycle body 2 with maintaining the securing function of the wheel securing assembly 12.
(2) The first locking member 32 is pivotable relative to the first axle end 28 about a first pivot axis PA1 to apply and release the securing force F1 to and from the bicycle body 2, and the first pivot axis PA1 is non-parallel to the center axis A1. Accordingly, it is possible to attach and detach the wheel securing assembly 12 to and from the bicycle body 2 in response to a pivotal movement of the first locking member 32.
(3) The receiving surface 46 is configured to face in a radial direction D2 perpendicular to the center axis A1 in the unlocking orientation of the second locking member 44. Accordingly, it is possible to more easily attach and detach the wheel securing assembly 12 to and from the bicycle body 2.
(4) The second locking member 44 is pivotable relative to the securing axle 23 about a second pivot axis PA2 to be in each of the locking orientation and the unlocking orientation. Accordingly, it is possible to easily change an orientation of the second locking member 44 between the locking orientation and the unlocking orientation relative to the securing axle 23 using a pivotal movement of the second locking member 44.
(5) The second pivot axis PA2 is defined to intersect with the center axis A1. Accordingly, it is possible to more easily insert the second locking member 44 into an opening of the bicycle body 2 in the unlocking orientation.
(6) The second locking member 44 is movable relative to the securing axle 23 in a movement direction D3 between the locking position P21 and the intermediate position P23 with maintaining the locking orientation relative to the securing axle 23. Accordingly, it is possible to make it difficult to unintentionally change the orientation of the second locking member 44 from the locking orientation to the unlocking orientation via the intermediate position P23. Thus it is possible to restrict the wheel securing assembly 12 from being unintentionally detached from the bicycle body 2.
(7) Since the second maximum distance L12 is longer than the first maximum distance L11, it is possible to more effectively restrict the wheel securing assembly 12 from being unintentionally detached from the bicycle body 2.
(8) The second locking member 44 is pivotable relative to the securing axle 23 about the second pivot axis PA2 between the intermediate position P23 and the unlocking position P22 with changing an orientation of the second locking member 44 between the locking orientation and the unlocking orientation. Accordingly, it is possible to more effectively restrict the wheel securing assembly 12 from being unintentionally detached from the bicycle body 2.
(9) The second locking structure 26 includes a holding structure 60 configured to hold the second locking member 44 to be in at least one of the locking orientation and the unlocking orientation. Accordingly, it is possible to make it easier to insert the second locking member 44 into an opening of the bicycle body 2.
(10) Since the holding structure 60 includes the holding and the biasing element 64, it is possible to make it easier to insert the second locking member 44 into an opening of the bicycle body 2 with a simple structure.
(11) The receiving surface 46 is in contact with the holding member 62 in the locking orientation of the second locking member 44. The additional receiving surface 66 is in contact with the holding member 62 in the unlocking orientation of the second locking member 44. Accordingly, it is possible to make it easier to hold the second locking member 44 in each of the locking orientation and the unlocking orientation.
(12) Since the third maximum distance L22 is longer than the minimum distance L21, it is possible to make it more difficult to unintentionally change the orientation of the second locking member 44 from the locking orientation to the unlocking orientation via the intermediate position P23. Thus it is possible to more effectively restrict the wheel securing assembly 12 from being unintentionally detached from the bicycle body 2.
(13) The additional receiving surface 66 of the second locking member 44 includes the first curved surface 66a. The holding surface 68 of the holding member 62 includes the second curved surface 68a contactable with the first curved surface 66a. Accordingly, it is possible to smoothly change the orientation of the second locking member 44 from the unlocking orientation to the locking orientation.
(14) The first curved surface 66a has a curved convex shape. The second curved surface 68a has a curved concave shape. Accordingly, it is possible to more smoothly change the orientation of the second locking member 44 from the unlocking orientation to the locking orientation.
(15) The second locking member 44 includes the elongated hole 52 and/or 54 extending along the receiving surface 46. The second locking structure 26 includes the guide pin 56 and/or 58 secured to the second axle end 30. The guide pin 56 and/or 58 extends through the elongated hole to guide the second locking member 44 relative to the securing axle 23. Accordingly, it is possible to realize the second locking structure 26 with a simple construction.
(16) The second locking member 44 includes the first part 47, the second part 48, the third part 50, the first guide pin 56, and the second guide pin 58. Accordingly, it is possible to realize the second securing structure with a simple construction.
(17) The receiving surface 46 is provided on at least one of the first part 47, the second part 48, and the third part 50. Accordingly, it is possible to stabilize a state in which the receiving surface 46 is in contact with the bicycle body 2.
(18) Since the maximum length L41 of the second locking member 44 is shorter than the maximum outer diameter L32 of the securing axle 23 when viewed along the center axis A1 in a state where the second locking member 44 is in the unlocking orientation relative to the securing axle 23. Accordingly, it is possible to more easily insert the second locking member 44 into an opening of the bicycle body 2 in the unlocking orientation.
(19) Since the first end 70 includes at least one curved corner, it is possible to more easily insert the second locking member 44 into an opening of the bicycle body 2 in the unlocking orientation.
(20) With the bicycle wheel assembly 10, it is possible to easily secure the bicycle hub assembly 14 to the bicycle body 2 via the wheel securing assembly 12.
