The moving section 54 is further down the bike 10 as the base section 52 , In one example, the brake disc cover 50 so on the bike frame 12 coupled that the belt part 52A of the base section 52 and the belt part 54A of the movable section 54 are parallel to the ground when the bike 10 for example, placed on the ground.

The base section 52 and the moving section 54 contain the same material. In one example, the base section 52 and the moving section 54 from a resin material. The base section 52 is an integrally molded component. The moving section 54 is an integrally molded component. The base section 52 and the moving section 54 are through the connecting sections 56 connected. Will the brake disc cover 50 on the bicycle frame 12 coupled, are the base section 52 and the moving section 54 connected to sections that are closer to the bicycle frame 12 are located as the end surfaces (hereinafter referred to as "the lower end surfaces 22X "Designated) of the bicycle frame 12 farthest to the bottom of the bike 10 sticking out. Will the brake disc cover 50 on the bicycle frame 12 coupled, are the base section 52 and the moving section 54 in the region R, by the bicycle frame 12 is defined, viewed in the direction of the rotation axis C, at least partially connected. The base section 52 and the moving section 54 are formed so that they are exactly circular when the base section 52 and the moving section 54 connected to each other. A boundary line K of the base section 52 and the movable section 54 runs straight between the belt part 52A of the base section 52 and the belt part 54A of the movable section 54 , The boundary line K passes through the rotational axis C of the brake disk 40 , The lower end surfaces 22X of the bicycle frame 12 are further down the bike 10 as the rotation axis C.

The first moving part 54X is any part of the moving section 54 , except for the belt part 54A , In 7 becomes the lower end of the movable section 54 as the first moving part 54X designated. The second moving part 54Y is spaced a second distance L2 from the axis of rotation C. The second distance L2 changes as the movable portion 54 relative to the base section 52 emotional. The second moving part 54Y is any part of the moving section 54 , except for the belt part 54A , In 7 becomes the lower end of the movable section 54 as the second moving part 54Y designated.

As in 5 is shown connect the connecting sections 56 the moving section 54 and the base section 52 so that the moving section 54 relative to the base section 52 is mobile. The connecting sections 56 connect the movable section 54 and the base section 52 so that the moving section 54 relative to the base section 52 is rotatable. The rotation of the movable section 54 around the connecting sections 56 moves the moving section 54 relative to the base section 52 , Each of the connecting sections 56 is a hinge. Each of the connecting sections 56 contains a first half 82 and a second half 84 that with the first half 82 connected via an axle member (not shown). In one example are the connecting sections 56 on a surface of the brake disc cover 50 that the brake disc 40 is opposite. In another example, there are the connection sections 56 on a surface of the brake disc cover 50 that the brake disc 40 is opposite. The belt part 52A of the base section 52 is the first half 82 coupled. In one example, the first half is 82 with a screw or the like on the base portion 52 attached. In another example, the first half is 82 integral with the base section 52 educated. The belt part 54A of the movable section 54 is the second half 84 coupled. In one example, the second half is 84 with a screw or the same at the base section 52 attached. In another example, the second half is 84 integral with the movable section 54 educated. The rotation of the second half 84 around the axle component with respect to the first half 82 turns the moving section 54 around the base section 52 , The connecting sections 56 are movable in a range in which, for example, an angle TA (see 7 ), from the first half 82 and the second half 84 is greater than zero degrees and less than or equal to 180 degrees. In this case, the second half moves 84 not closer to the brake disc 40 as the first half 82 , In particular, the moving section moves 54 not closer to the brake disc 40 as the base section 52 ,

The restriction section 58 is a rod-shaped component. The restriction section 58 contains a first part 86 , a second part 88 and a third part 90 , The second part 88 is an end of the rod-shaped component. The second part 88 is tapered so that its diameter decreases towards the end. The third part 90 is the other end of the rod-shaped component. The first part 86 is a section between the second part 88 and the third part 90 , The first part 86 and the second part 88 are straightforward. The restriction section 58 is between the first part 86 and the third part 90 bent. The bending angle of the restriction section 58 is for example 90 degrees. Thus, the third part runs 90 orthogonal to a direction in which the first part 86 and the second part 88 run.

The restriction section 58 is detachable to the base section 52 and the moving section 54 coupled. The restriction section 58 limits the movement of the movable section 54 relative to the base section 52 , The first part 86 of the restriction section 58 is in the first insertion part 74 of the base section 52 inserted. The second part 88 of the restriction section 58 is in the second insertion part 80 of the movable section 54 inserted. The second insertion part 80 is designed to be the movement of the second part 88 with the in the second insertion part 80 inserted second part 88 limited. The second insertion part 80 is for example made of rubber, in which a hole runs. The hole has a smaller diameter than the second part 88 , So if the second part 88 pressed into the hole, limiting the friction of the second part 88 and rubber the movement of the second part 88 ,

Now, the operation and advantages of the brake disc cover 50 with reference to the 1 to 7 described.

A person raises the lever 36 the attachment mechanism 18 and thus solves the force of the attachment mechanism 18 who the bicycle hub 14 and the bicycle frame 12 stop. The person removes the mother 32A from the axle component 32 and then the axle component 32 from the hub axle 28 , So can the wheel 16 and the bicycle hub 14 from the bicycle frame 12 be removed. Is that the wheel 16 from the bicycle frame 12 the person removes the restriction section 58 from the first insertion part 74 and second insertion part 80 , As a result, the moving section becomes 54 the brake disc cover 50 relative to the base section 52 movable. As in 6 is shown, a state is reached in which the movable portion 54 relative to the base section 52 rotates. Thus, the lower end surfaces can 22X of the frame body 22 further down than the belt part 54A of the movable section 54 , So can the lower end faces 22X of the frame body 22 for example, come into contact with the ground. Now wear the lower end surfaces 22X of the bicycle frame 12 the load of the bicycle 10 even if the second peripheral part 78 of the movable section 54 is in contact with the ground.

For example, in a prior art brake disk cover, when the lower end of the cover portion is located lower than the lower end surfaces of the frame body, contact of the lower end of the cover portion with the floor or the like may deform the brake disk cover. At the bicycle 10 to which the brake disc cover 50 coupled, wear the lower end surfaces 22X of the bicycle frame 12 the load of the bicycle 10 , This limits the load on the brake disc cover 50 through the bike 10 , Thus, the brake disc cover 50 made of a material with a lower rigidity than the material of the bicycle frame 12 be made.

The moving section 54 is like that with the base section 52 connected to that the moving section 54 not closer to the brake disc 40 moved as the base section 52 , Thus, for example, even if the restriction section 58 not in the first insertion part 74 and the second insertion part 80 is inserted, the contact of the movable section 54 with the brake disc 40 limited. For example, the movable section 54 while the wheel 16 on the bicycle frame 12 is coupled, the brake disc 40 less likely to contact and attach the wheel 16 hinder.

The above description illustrates one embodiment of a brake disk cover according to the present invention and is not intended to be limiting. The brake disk cover of the present invention may be modified as follows, for example. Further, two or more of the modified examples may be combined.

Each of the connecting sections 56 the brake disc cover 50 can to the in 8th shown connection section 92 to be changed. The in 8th shown connection section 92 the brake disc cover 50 is bendable. The connecting section 92 is made of a resin material, for example. The connecting section 92 is with the base section 52 and the moving section 54 connected. In one example, the connection section 92 integral with the base section 52 and the moving section 54 educated. In this case, the connection section 92 as a thin part of the cover portion 60 educated. In another example, the connection section is 92 separate from at least one of the base portion 52 and the moving section 54 formed and with the aid of an adhesive, a screw member or the like with at least one of the base portion 52 and the moving section 54 connected. As in 8th shown by the two-dot chain lines, the bending of the connecting portion moves 92 relative to the base section 52 and the moving section 54 the moving section 54 relative to the base section 52 ,

The moving section 54 the brake disc cover 50 can to the in 9 shown movable section 94 to be changed. The in 9 shown moving section 94 the brake disc cover 50 is bendable. The moving section 94 is made of a resin material, for example. The moving section 94 is with the base section 52 connected without a connection section. In one example, the moving section 94 integral with the base section 52 educated. In this case, the base section 52 and the moving section 94 integrally molded from the same material. Alternatively, the base section 52 and the moving section 94 formed of different materials and integrally formed by means of insert molding. Are the base section 52 and the moving section 94 integrally molded from the same material is the base portion 52 to bending. As in 9 shown by the two-dot chain lines, the bending of the movable section moves 94 relative to the base section 52 the moving section 94 relative to the base section 52 ,

At the brake disc cover 50 can the base section 52 with the moving section 54 be so connected that the base section 52 is designed so that it moves from the movable section 54 can be separated. As in 10 is shown, the base section 52 and the moving section 54 for example, with a screw component 96 attached. In this case, the detachment of the movable section moves 54 from the base section 52 the moving section 54 relative to the base section 52 , In this case, the screw component corresponds 96 a restriction section. In this modified example, the release of the nut 32A the attachment mechanism 18 from the axle component 32 and the release of the axle component 32 from the hub axle 28 be excluded when the wheel 16 and the bicycle hub 14 from the bicycle frame 12 be solved.
