Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a mudguard device for a bicycle that is sold and used without a mudguard attached.

[0002]

[Prior art]

 Bicycles such as so-called mountain bikes (MTBs) and road racers usually do not come with a mudguard. For this reason, when riding on a wet road or muddy ground, the splattering rises and the rider and clothes are soiled. Therefore, a muffler that can be attached to this type of bicycle has been proposed (Shokai Sho 60-160286), but it is not easy and requires a lot of effort to attach it to the bicycle.

[0003]

[Problems to be solved by the device]

 The present invention has been made in view of the above points, and the problem is to be easily attached, small in size, and to obtain a large repellent effect.

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention provides a front mudguard body 10 having a front curved plate portion 12 extending rearward substantially along a front wheel from a mounting plate portion 11 having a front shape adapted to the shape of a front fork of a bicycle. And a recessed portion 15 for mounting the bolt 14 in the through hole 13 formed in the front fork in the front-rear direction is formed in the front portion of the upper surface of the curved plate portion 12, and the front portion of the recessed portion 15 is provided. And a rear side of the mounting plate 11 are formed with a groove 16 having an upward opening, and a reinforcing piece 18 having a small hole 17 through which the bolt 14 is formed is fitted into the groove 16 to form the front mudguard main body 10 The bolt 14 and the nuts 19 are fastened to the upper portion of the front fork.

[0005]

【Example】

 FIG. 1 shows a mounting state of the front mudguard body 10. The front mudguard body 10 is equipped with a mounting plate part 11 having a substantially semi-circular front shape that conforms to the shape of the upper part of the front fork F of the bicycle at one end, and the mounting plate part 11 is attached to the front wheel. A forward curved plate portion 12 extending rearward is provided. The front curved plate portion 12 has side pieces 31 extending from both the left and right sides of the mounting plate portion 11 on both sides of the front portion, and has a length to prevent the front wheels from splashing on the rider.

A recess 15 for passing the bolt 14 in the front-rear direction is formed in the main body 10 behind the mounting plate 11. The recessed portion 15 illustrated is a form in which the front surface of the front portion of the main body is largely recessed for the purpose of reinforcement, but it is basically sufficient if the head portion of the bolt 14 can be operated. At the front end of the recessed portion 15, that is, at the rear side of the mounting plate portion 11, a small hole 17 through which the bolt 14 that passes from the recessed portion 15 is formed is formed. A groove 16 that is opened upward for fitting the reinforcing piece 18 Are formed in the left-right direction (FIG. 3). The reinforcing piece 18 is made of metal and has protrusions 17 'for preventing it from slipping out on both sides. Reinforce 10 side.

Reference numeral 33 denotes a support protrusion provided in the lower central portion of the mounting plate portion 11 and engages with the lower end of the handle tube combined with the front fork F. Reference numeral 34 denotes a spacer, which is interposed between the mudguard main body 10 when the mudguard main body 10 hits the triangular frame, and a small hole 35 is provided in the central portion for bolting. Reference numeral 36 is a safety hook arranged on the front surface of the front fork F and fastened by the bolt 14, which also has a bolt hole 37. The nuts 19 screwed onto the bolts 14 may or may not be cap nuts, but preferably have locks.

In such a front mudguard body 10, the mounting plate portion 11 on the front surface thereof is applied to the rear side of the front fork upper portion, and is formed from the small hole 17 of the reinforcing piece 18 to the upper portion of the front fork F. The bolt 14 is passed through the hole 13 and loosened by the nuts 19 so that the mounting plate portion 11 is brought into pressure contact with the front fork F and is stably mounted.

FIGS. 2 and 4 show how the rear mudguard body 20 is attached. Two types of the rear mudguard body 20 are prepared according to the structure around the rear fork.

FIG. 2 is for a bicycle having small members S on the left and right of the upper part of the rear fork R. The left and right holding parts 21, 21 ′ sandwiching the left and right outer parts of the upper part of the rear fork of the bicycle are almost along the rear wheel. And a rear mudguard body 20 having a rear curved plate portion 22 extending rearward. The small fork S of this type of rear fork R is provided with an insertion hole 23 in the front-rear direction, and the rear mudguard main body 20 is screwed by a set screw 24 passing therethrough. The mounting bracket 25 for that purpose has left and right side pieces 41, 41 'formed in a substantially U-shape in plan view, and female screw holes 42, 42' are formed therein, and the left and right holding parts 21, 21 'are formed. It is screwed together with the through holes 43 and 43 'by the additional screws 44 and 44'.

Therefore, the left and right holding parts 21, 21 ′ of the rear mudguard body 20 fitted with the fitting 25 are fitted to the outer side of the frame of the rear fork R, and then the set screw 24 is inserted into the through hole 45 of the fitting 25 and the through hole. It is sufficient to pass through 23 and fasten with nuts 46. For this reason, the rear mudguard body 20 is stably attached so that the right and left holding parts 21, 21 'come into contact with the rear fork R so as to hold it from the outside.

Since the example of FIG. 4 does not have a small member, a tightening plate 26 instead of this is arranged in front of the rear fork R, and an insertion hole 27 is formed in it so that fastening with a set screw 28 is possible. Is. If the rear fork R has the dowel 38, the notch 39 of the mounting member 25 is aligned with it. Reference numeral 29 denotes a through hole formed in the mounting member 25, which is provided at two positions in accordance with the insertion hole 27. The mounting member 25 has a substantially U shape in plan view, and the structure for mounting it on the rear mudguard main body 10 may be the same as that in the example of FIG. 2 described above. The setscrews 24, 28 are equivalent to the bolts 14 for mounting the front forks F.

[0013]

[Effect of device]

 Since the present invention is constructed and operates as described above, the resin front mudguard body 10 and the left and right gripping parts 21, 21 'and the rear part which are integrally formed with the mounting plate part 11 and the front curved plate part 12 are provided. The rear mudguard body 20 in which the curved plate portion 22 is integrated with several pieces of metal is combined, and the front fork and the rear fork can be screwed to the front portions of the respective main bodies 10 and 20, so that the mounting is very easy. It has the effect of being easy to perform and of achieving high stability.
