BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fender for a bicycle.

[0002]

2. Description of the Related Art Fenders (covers for mudguards) provided to cover upper outer circumferences of front and rear wheels of a bicycle are well known. The most common mounting structure for this type of fender is one in which the fender and the lower end of the wheel holding fork (the fastening portion of the axle) are connected by a wire that is slightly longer than the radius of the wheel. Such a structure is not suitable in terms of appearance, and in recent years mountain bikes and the like have problems in terms of mounting strength and weight burden, and the shape, structure and dimensional relationship of the wheel holding hawk are various. Was not adopted because it was difficult to cope with it.

[0003] The present invention has been made in view of the above circumstances, and has excellent appearance and mounting strength, reduces the weight burden, and can be mounted on the mounting surface without being greatly affected by the type of bicycle. An object of the present invention is to provide a bicycle fender in which the versatility of the bicycle is improved.

[0004]

In the present invention, the following technical measures have been taken in order to achieve the above object. In other words, the present invention provides a bicycle fender having a mud receiving piece that covers the outer periphery of the upper side of the wheel, and a mounting piece that projects from the mud receiving piece toward the wheel. The mounting piece is characterized in that a mounting arm which can be fastened together with a fastening portion for mounting the brake device to the wheel holding fork is detachably connected to the mounting piece.

[0005] It is preferable that the position of the connection between the mounting piece and the mounting arm can be relatively adjusted along the vertical direction. In the mud receiving piece, a notch is formed between the main body disposed on the rear side of the wheel holding fork and a tip protruding forward of the main body to induce a crack when separation is necessary. Can be kept.

[0006] It is preferable that the mounting arm is provided with a structure capable of adjusting the length of the bicycle along the longitudinal direction.

[0007]

According to the present invention, the entire fender is mounted on the bicycle through the mounting arm by fixing the mounting arm to the fastening portion where the brake device is mounted on the wheel holding fork. . Therefore, the appearance and the mounting strength are excellent. Moreover, the brake device is an indispensable element as a bicycle, and most bicycles also have a fastening portion with the wheel holding fork, but it is difficult to fix the mounting arm using this fastening portion. For example, as seen in mountain bikes, etc., a suspension mechanism is attached to the wheel holding hawk, or the wheel holding hawk is not bifurcated but only one, so it has a completely different structure from a general bicycle. Even if it is provided, there is an advantage that the fender itself can be applied as it is by slightly changing the shape of the mounting arm.

If the position of the mounting piece and the mounting arm can be relatively adjusted along the vertical direction, or if the length of the mounting arm itself can be adjusted along the front and rear direction, the fender can be mounted. Since the number of types of bicycles to be used can be increased, the types of mounting arms can be minimized to prevent an increase in manufacturing cost and facilitate management in product distribution.

If a notch is formed in the mud receiving piece, the presence or absence of the tip can be selected according to the user's preference and the type of bicycle, which is convenient.

A pocket portion 7 for fitting the protruding end portion of the arm 10 is formed, and a long hole 6 extending vertically is formed between the ribs 8. The ribs 8 and the long holes 6 enable the vertical position of the mounting arm 10 to be adjusted.

The mud receiving piece 2 has a length that covers about 1/8 of the outer circumference of the rear wheel 50. With respect to the main body portion 2a on the rear side of the wheel holding fork 51,
The wheel holding fork 5 is formed so as to protrude forward and partially
Tip portion 2 projected further forward than 1
As shown in FIG. 4, b can be separated from the main body portion 2a along a V-groove-shaped notch portion 5 formed so as to partition between these two portions (2a, 2b). When it is necessary to separate the bicycle according to the user's preference or the type of bicycle, simply turning the tip portion 2b by hand causes a crack along the notch portion 5. Reference numeral 4 in FIG.
Are wings formed mainly from a design point of view.

As shown in FIG. 5, the mounting arm 10 has a substantially L-shape as a whole made of a corrosion-resistant metal strip or the like.
In addition, the fastening piece 11 is formed so as to protrude laterally from the protruding end, and is arranged on the right side with respect to the bicycle by changing the projecting direction of the fastening piece 11 (10a). And one for the left side arrangement (10b) are prepared. A vertically long portion of the L-shape is a portion to be inserted between the ribs 8 of the mounting piece 3 described above, and a screw hole 13 subjected to burring or the like is formed at an appropriate height position. ing. A through hole 12 is formed in the co-fastening piece 11.

As shown in FIG. 6, this embodiment shows a cantilever type brake device 60. Therefore, the brake device 60 is fastened to the forked brake table 65 having the wire holding cylinder 62 by the bolt 61 (fastening portion 64), and the brake table 65 is connected to the wheel holding fork 5
The screw receiving boss 52 welded to 1 is fastened by a bolt 56 (fastening portion 63). Therefore, the fastening portion 63 (or 64) may be
The fender 1 is mounted by interposing the co-fastening piece 11 of the mounting arm 10 described above. Reference numeral 55 denotes a gap adjusting collar. In some cases, the brake table 65 is not provided. In this case, the brake device 60 is directly fastened to the screw receiving boss 52 of the wheel holding fork 51. Needless to say, mounting is performed. Further, in another type of brake device (for example, center pull type: not shown), a central hole (not shown) formed in a member (for example, reference numeral 57) provided integrally or separately between the forks of the wheel holding fork 51. On the other hand, the mounting may be performed by fastening the center support shaft of the brake device. However, it is also possible to mount the fender 1 using such a fastening portion. Of course,
The shape of the mounting arm 10 needs to be changed to each corresponding shape.

A screw hole 102 for zero is formed. With this mounting arm 10, since the types of bicycles to which the fender 1 can be mounted increase, the types of the mounting arm 10 can be reduced. Such a structure is of course also applicable to the mounting arm 10 for the rear wheel 50 (see FIG. 5).

[0017]

The present invention has the above-described structure, and has a structure in which the fender is mounted by using a fastening portion for mounting the brake device to the wheel holding fork, so that the appearance is neat. As a result, a firm state of the mounting strength can be obtained. Also, since the brake device is indispensable as a bicycle, most bicycles also have a fastening portion with the wheel holding hawk. Since this fastening portion is used, the shape of the mounting arm is slightly changed. Just by changing it, the fender itself can be mounted in the same shape. Therefore, even if the bicycle has a completely different structure from a general bicycle, such as a mountain bike, it can be mounted, but rather the novelty of the appearance, the robustness of the mounting strength, the reduction of the weight burden, the functionality, It can be said that it is suitable for such a special vehicle from the viewpoint of mounting possibility (versatility) and the like.

If the mounting arm can be adjusted up and down with respect to the mounting piece, or the mounting arm itself can be adjusted back and forth, the type of the mounting arm can be minimized in any case, and the manufacturing cost rises. Prevention and simplification of product management can be achieved. If a notch is formed in the mud receiving piece, the presence or absence of the tip can be selected according to the user's preference or the type of bicycle, which is convenient.
