Reference is first made to Figures 1 and 2. 1 shows a side view of a bicycle 10 equipped with a locking member for a bicycle component (hereinafter simply referred to as "locking member", see FIG. 2) 20 in accordance with an embodiment of the present invention. In this embodiment, the bicycle 10 is a road bicycle including a bicycle frame 11, a front fork 12 mounted to the bicycle frame 11, and mounted on the front fork 12. a handlebar assembly 13, a front wheel 14F rotatably attached to the lower portion of the front fork 12, a rear wheel 14R rotatably attached to the rear of the bicycle frame 11, a chain 15, a front derailleur 16, and a rear derailleur 17. The tire TF is attached to the front wheel 14F, and the tire TR is attached to the rear wheel 14R.

The bicycle 10 also includes a disc brake. The disc brake includes a bicycle disc brake rotor (hereinafter simply referred to as "brake rotor") 30 (see FIG. 2), and a brake caliper (not shown), the brake caliper including a pair of brake pads (not shown) ). As shown in FIG. 2, the brake rotor 30 is fixed to the bicycle hub assembly (hereinafter simply referred to as "hub assembly") 40 of the rear wheel 14R by the first locking member 20. When a bicycle is required to be braked, the pair of brake pads are actuated such that the pair of brake pads are pressed against the brake rotor 30 to lower the bicycle by friction between the pair of brake pads and the brake rotor 30 10 speeds.

In addition, the front derailleur 16 is a mechanical unit attached to the lower middle portion or the bottom bracket of the bicycle frame 11, and is used to transmit the driving force generated by the rider to the rear derailleur 17 via the chain 15. The front derailleur 16 includes a first front chain wheel G1, a second front sprocket G2, and a front derailleur 18. The first and second front sprockets G1 and G2 are mounted on a gear crank C rotatably driven by the pedal P, and the first front sprocket G1 may have fewer teeth and a smaller diameter than the second front sprocket G2. The front derailleur 18 selectively switches the chain 15 to the first front sprocket G1 or the second front sprocket G2 by selectively pulling and releasing the control cable in the form of a Bowden cable. Alternatively, the front derailleur 18 selectively switches the chain 15 to the first front sprocket G1 or the second front sprocket by a derailleur actuator such as an electric motor. G2.

For the sake of clarity, FIG. 2 shows the assembled relationship between the first locking member 20, the brake rotor 30, the hub assembly 40, the multi-sprocket assembly 50, and the second locking member 20 in an exploded perspective view. Specifically, the brake rotor 30 is coaxially fixed to one end of the hub assembly 40 by the first locking member 20, and the multi-sprocket assembly 50 is coaxially fixed to the other end of the hub assembly 40 by the second locking member 20. on.

Next, the locking member 20 and the mating structure of the locking member 20 and the hub assembly 40 according to the present embodiment will be described in detail with reference to FIGS. 3-9.

First, referring to Figures 6-9, these figures show a front perspective view, a rear perspective view, a front view, and a side view, respectively, of the locking member 20.

As shown in Figures 6-9, the locking member 20 has a first central axis X. The locking member 20 includes a through hole 25, and a first profile 21 and a second profile 22.

As shown in FIG. 2, the through bore 25 is configured to receive the hub axle 43 of the hub assembly 40 such that the hub axle 43 passes through the through bore 25. Specifically, for the first locking member 20, its through hole 25 will receive one end of the hub axle 43 to which the brake rotor 30 is to be mounted. For the second locking member 20, its through hole 25 will receive one end of the hub axle 43 to which the multi-sprocket assembly 50 is to be mounted.

Preferably, the through hole 25 is formed at the center of the locking member 20 along the first central axis X. The through hole 25 may have a second central axis Y that is disposed coaxially with the first central axis X. For example, the through holes 25 may be formed as through holes having the same circular cross section.

The first profile 21 can be used for the first tool to engage and form in the first position. The second contour 22 is operable for the second tool to engage and be formed in the second position, the second position being different than the first position.

That is, at the first contour 21, the user can engage the first contour 21 with a first tool (not shown) having a shape that is compatible with the shape of the first contour 21. Thus, in accordance with the present invention, bicycle components such as brake rotor 30 and multi-sprocket assembly 50 can be locked to hub assembly 40 by a first tool or the bicycle component can be removed from hub assembly 40. Further, at the second contour 22, the user can adopt the A second tool (not shown) is provided that is adapted to the shape of the second contour 22 to engage the second contour 22. Thus, in accordance with the present invention, a bicycle component, such as brake rotor 30 and multi-sprocket assembly 50, can be locked to hub assembly 40 by a second tool or the bicycle component can be removed from hub assembly 40. According to the present invention, the first contour 21 and the second contour 22 may be different in size and/or shape such that different first and second tools may be employed to mount/disassemble the bicycle component. Therefore, the user's selection of the tool is increased, thereby facilitating the user's use.

Specifically, as shown in FIGS. 6-9, the first contour 21 may be a first concave and convex contour formed on the first position, and the second contour 22 may be a second concave and convex contour formed on the second position. Preferably, the shape of the first relief profile can be designed to match the fingers of a human so that the user can directly attach/detach the bicycle component by hand without the use of a tool. The shape of the second relief profile may be similar or different from the shape of the first relief profile. For example, the shape of the second relief profile can be designed such that the user can directly attach/detach the bicycle component by hand, or can be designed such that the user can use tools to attach/detach the bicycle component. That is, in this alternative embodiment, the user can attach/detach the bicycle component by hand and/or a combination of hand and tool, increasing the user's choice and thus facilitating the user's use.

A person skilled in the art can select the set positions of the first contour 21 and the second contour 22 as needed. According to the present invention, the first position can be selected to be positioned radially outward from the second position relative to the first central axis X. That is, the first contour 21 can be positioned radially outward from the second contour 22 relative to the first central axis X.

In addition, the locking member 20 may have a radially inner peripheral surface with respect to the first central axis X. As shown in FIG. 6, the radially inner peripheral surface defines a through hole 25. The second contour 22 may be formed on the radially inner peripheral surface. Preferably, the radially inner peripheral surface is annular.

The annular radially outer peripheral surface and the radially inner peripheral surface are relatively easy to manufacture and make it easier for the user to attach/detach the bicycle component by hand and/or tool.

As shown in FIGS. 7 and 9, the locking member 20 may have a flange portion 23 and a shaft portion 24. The first contour 21 and the second contour 22 may be formed on the flange portion 23. The shaft portion 24 can have an externally threaded portion 241 to engage the internal threaded portions 41, 42 of the hub assembly 40 (shown in Figures 3-5). The locking member 20 secures the bicycle components, such as the brake rotor 30 and the multi-sprocket assembly 50, to the hub assembly 40 by the snap fit of the externally threaded portion 241 of the shaft portion 24 with the internally threaded portions 41, 42 of the hub assembly 40. on.

According to the present novel, the strength of the locking member 20 can be increased by a combination of both the flange portion 23 and the shaft portion 24. That is, even if the length of the flange portion 23 in the axial direction parallel to the first central axis X (or the thickness of the flange portion 23) l is small, the strength of the locking member 20 may be due to the shaft portion 24.
