On the upper surface of the carrier portion, the longitudinal direction is
The anti-skid table facing upwards from the upper surface of the carrier part
A protruding configuration can be adopted (claim 2 ). With such a configuration, it is possible to prevent the luggage from laterally moving or falling off when the luggage is placed on the carrier unit. In addition, such an anti-slip platform has a reinforcing effect on the carrier portion (corresponding to a part of the fender body).

[0008] At least one of the anti-skid bases may be arranged at the center in the width direction of the carrier portion, and the anti-skid base may be extended to the upper surface of the fender body. (Claim 3 ). With such a configuration, the effect of reinforcing the fender body by the sideslip prevention stand can be more positively obtained. Here, the center in the width direction of the carrier portion does not limit the “center in the width direction”, but refers to the “portion” corresponding to the positioning of the fender body.

A lower rib extending in the front-rear direction is provided on the back surface of the carrier portion, and a frame for attachment to a vehicle is provided along the lower side of the lower rib. Is possible (claim 4 ). With such a configuration, the reinforcing effect of the carrier portion can be obtained not only by the anti-skid stand but also by the lower rib, and the strength of the carrier portion in the up and down directions can be enhanced.

[0010] Further, since the mounting frame to the vehicle body is brought into contact with the lower rib along the lower side, the load of the load placed on the carrier portion is directly applied to the mounting frame. The carrier is hardly bent.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 5 shows a state in which a fender device 1 according to one embodiment of the present invention is mounted on a leisure bicycle 3 via a mounting frame 2. This fender device 1 has a fender body 5 as shown in FIGS.
Is provided with a carrier portion 6.

The fender body 5 is formed in an arc shape so as to cover the upper part of the rear wheel 9 by about 1/5 circumference behind the upper end of the back fork 8. The carrier portion 6 is formed such that the upper surface portion of the portion corresponding to the top is spread flat in the width direction. That is,
The carriage device 1 has a carrier widened in the width direction at the front side thereof.
A part 6 is provided and formed narrower on the rear side than the carrier part 6.
The fender body 5 is provided.

The fender body 5 and the carrier 6 are integrally formed of, for example, a nylon resin material. On the upper surface of the carrier part 6, the longitudinal direction is in a bank shape with the longitudinal direction being forward and backward.
A plurality of anti-skid base 10 of (was four in the illustrated example) is provided which projects. The front end portions of the anti-skid tables 10 abut against a stopper portion 11 protruding across the upper surface of the carrier portion 6 in the width direction. The stopper 11 has a trapezoidal shape when viewed from the front as shown in FIG.

A plurality of through-grooves 12 are formed in each anti-slip table 10 at predetermined intervals in the front-rear direction (see FIGS. 1 and 2). These passage grooves 12 are provided in the carrier portion 6.
Are arranged obliquely in such a manner that the inclination directions are opposite on both sides of the center in the width direction. In addition, these through-grooves 12
May penetrate the carrier portion 6 in the up-down direction or may not penetrate the carrier portion 6 depending on the formation convenience. Even if it penetrates, the opening area is very small, so that the splash from the rear wheel 9 does not jump onto the carrier part 6 through this penetrating part. Rather, an effect of gradually dropping rainwater or the like accumulated on the carrier portion 6 can be expected.

For this reason, the load placed on the carrier unit 6 is subjected to the side slip prevention operation by the anti-skid table 10 and the forward movement prevention operation by the stopper unit 11, and furthermore, the forward / backward / left / right operation by the passage groove 12. A movement inhibiting action (edge effect) is provided, so that a position shift or dropping on the carrier section 6 is prevented. Two of the anti-skid tables 10 arranged near the center in the width direction of the carrier portion 6 extend not only to the carrier portion 6 but also to the rear thereof to reach the upper surface portion of the fender body 5. (See FIGS. 2 and 4).

On the back surface of the carrier portion 6, there are provided lower ribs 15 extending frontward and rearward in correspondence with the two anti-skid tables 10 arranged at the center in the width direction, and Two width-direction ribs 16 are provided to intersect in a grid and extend in the width direction (see FIGS. 3 and 6). Note that, in the anti-skid table 10 of the central arrangement corresponding to the lower rib 15, a groove 17 is formed on the back surface of the fender main body 5 behind the position where the lower rib 15 is formed (a portion corresponding to the fender main body 5). It has a hollow structure (see FIG. 9). Also, in the sideslip prevention stand 10 arranged on both sides in the width direction of the carrier part 6,
A hollow structure is formed over the entire length by forming a groove 18 on the back surface of the carrier portion 6 (see FIG. 8).

As described above, since the anti-skid base 10 has the unevenness in the vertical direction with respect to the carrier portion 6 and the fender main body 5, it has a reinforcing effect on each of them. Particularly, at the center in the width direction of the carrier portion 6, since both the anti-skid table 10 protruding upward and the lower rib 15 protruding downward are provided, the strength of the carrier portion 6 in either the upper or lower direction is ensured. Is also enhanced.

At the position corresponding to the center in the width direction of the carrier portion 6, a boss portion 20 used for coupling with the mounting frame 2 is formed on the width direction rib 16 described above. A central hole is formed in the boss portion 20 so as to penetrate vertically.
The mounting bolt 2 is inserted into the center hole from above the carrier 6.
3 (see FIG. 8). A counterbore is formed in the center hole on the upper surface side of the carrier portion 6 so that a bolt head of the mounting bolt 23 can be stored.

The width direction rib 16 has a larger downward projection than the lower rib 15 (FIGS. 6 and 8).
At these intersections, cutouts 24 are formed that open front and rear and below so as to form a through space in the front and rear direction according to the amount of projection of the lower rib 15.
On the other hand, as shown in FIG. 6, the mounting frame 2 has a frame body 26 formed by bending a linear material into a U shape, and two longitudinal portions of the frame body 26. And two connecting bars 27 attached by welding so as to cross the frame, and a breath connecting portion 28 attached to the frame body 26 by welding between the connecting bars 27.

As shown in FIGS. 3 and 8, the frame main body 26 has a length and a width interval capable of making contact with the entire length of the two lower ribs 15 with respect to the back surface of the carrier portion 6. Further, it has an attachment stay 26a that projects forward of the carrier 6 (the fender device 1). The connecting bar 27 is provided at a position corresponding to the width direction rib 16 in the carrier portion 6, and a connecting seat portion 27 a corresponding to the boss portion 20 is formed at a center portion in the width direction thereof. This coupling seat 27
A is formed with a bolt insertion hole.

A string hook 32 is formed on the connecting bar 27 so that both sides in the width direction are bent downward from the carrier 6. The breath connecting portion 28 is bent forward and obliquely downward on both sides in the width direction, and a polymer piece 28a is formed at a protruding end thereof to facilitate connection with the breath 34. The breath 34 connected to the overlapping piece 28a is connected to the backhawk 8 of the bicycle 3 (see FIG. 5).

As shown in FIG. 6, the breath 34 is provided with two screw insertion holes in parallel so that the connection position with respect to the breath connection portion 28 can be adjusted (the hole may be an elongated hole). Therefore, in order to couple the mounting frame 2 to the fender device 1, the frame main body 26 of the mounting frame 2 is brought into contact with the back surface of the carrier 6 along the lower rib 15 (on the way, The frame main body 26 is fitted into the notch 24),
The connecting seat 27 a of the connecting bar 27 is matched with the boss 20.

Then, the boss portion 20 is placed on the carrier portion 6 from above.
The mounting bolt 23 is inserted into the center hole of the nut, and the nut 35 is inserted into a portion where the mounting bolt 23 protrudes from the coupling seat 27a.
(See FIGS. 3 and 8). By doing so, the strap portion 32 is provided around the periphery of the carrier portion 6, which is convenient for packing and the like.

With the mounting frame 2 coupled to the fender device 1 in this manner, the mounting stay 2 of the mounting frame 2 is
What is necessary is just to screw the 6a and the breath 34 into place in the frame of the bicycle 3. In this case, as shown in FIG. 5, the main area (see arrow X) of the upper surface of the carrier unit 6 is the bicycle 3
If the arrangement is such that it is included in the downward projection range of the saddle 36 at
The saddle 36 is in the way, making it impossible or difficult to seat. Therefore, prevention of two-seater can be achieved.

The present invention is not limited to the above embodiment. For example, the fender body 5 and the carrier portion 6 may be formed separately, and these may be integrally connected by bonding or screwing. The detailed shapes and the like of the fender body 5 and the carrier section 6 can be appropriately changed.
For example, in the fender main body 5 in the illustrated example, the rear end portion thereof is slightly flipped up, so that a spoiler function can be obtained substantially or in appearance. Needless to say, this is in a category that can be appropriately selected according to the embodiment, and the length of the fender body 5 can be arbitrarily changed .

The shape and presence / absence of the stopper portion 11 and the passage groove 12 can be arbitrarily changed. The material for forming the fender body 5 and the carrier 6 is not limited at all. In some cases, such as the structure and shape of the mounting frame 2, the presence or absence thereof is not limited at all.

The type of the bicycle 3 is not limited. Also, the present invention can be applied to a motorized one (including a motorcycle or the like).
