Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a dress guard for a bicycle that prevents the clothes of a rider from getting caught in the rear wheel of the bicycle.

(Prior art) As this type of conventional technology, for example,
Some of these are disclosed in Japanese Utility Model Publication No. 184787 and Japanese Utility Model Application Publication No. 184788/1983.

(Problems that the invention aims to solve) However, all of the conventional devices mentioned above have complicated structures, increase manufacturing costs, and cannot be attached or detached freely, so even if you try to clean the inside of the dress guard, you cannot easily remove it Moreover, even if a dress guard is not required, it cannot be easily removed by an amateur.

Furthermore, the above-mentioned conventional device has a problem in that it is not very usable because the number of bicycles to which it can be attached is limited to a very narrow range depending on the shape and dimensions of the bicycle to which it is to be attached.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention includes two substantially fan-shaped guard plates with a plurality of holes provided along at least the linear edges, and an elastic guard plate. A curved recess into which one backhawk can be fitted and fixed is formed near the starting end of the band made of wood, and the extension of the band is passed through the upper surface of the mudguard on either the front or back of the backhawk to the other side. to the backhawk, form the curved concave notch at the intersection with the backhawk, and further overlap the extension part of the band with the starting end of the band through the upper surface of the mudguard on either the front or rear of the backhawk. A dress guard for a bicycle is constituted by a band having engaging protrusions protruding from the inside of the band between the backhawk and the mudguard, which can be press-fitted into the holes of the guard plate and locked.

(Function) As mentioned above, in the present invention, the bicycle dress guard is composed of two substantially fan-shaped guard plates and one band made of elastic material.
It has the advantage of simple structure and low manufacturing cost.

In addition, even an amateur can easily assemble and disassemble it, so it can be used when cleaning the inside of the dress guard,
It is very convenient because it can be easily removed when the dress guard is not needed.

Furthermore, since the present invention uses a stretchable elastic band to attach the dress guard to the bicycle, the dress guard can be attached even if the shape and dimensions of the bicycle change considerably. Therefore, the device of the present invention has the advantage that it has a wide range of applications.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings. In the figure, 1 is a bicycle vertical pipe, 2 is a chain stay, 3 is a backpack hawk, 4 is a rear wheel, 5 is a mudguard,
6 is a mudguard stay, and 7 is a saddle.

In this embodiment, two guard plates 9 are formed by forming a perforated plate having a large number of holes 8 distributed in a substantially fan shape.
form.

This guard plate 9 only needs to be provided with a plurality of holes 8 along at least a straight edge.

The starting end 10a of the band 10 made of an elastic material such as rubber or synthetic resin is formed into a stepped shape as shown in FIG. Backpack Hawk 3
As shown in FIG. 4, the lower part of the band 10 is formed with a curved recessed notch 10b that can be fitted and fixed, and the extended part of the band 10 is inserted into the mud from either the front or rear of the backhawk 3 (in this embodiment, the rear). The band 10 is guided through the upper surface of the band 5 to the lower part of the backhawk 3 on the other side (the right side in this embodiment), and the curved recessed notch 10b is formed at the intersection with the backhawk 3, and the extension of the band 10 is It is made to be able to overlap the starting end 10a of the band 10 through the upper surface of the mudguard 5 on either the front or rear side of the backhawk 3 (in this embodiment, the front side). Reference numeral 10c indicated by a two-dot chain line in FIG. 2 is a terminal end portion of the belt 10 formed in a stepped shape so as to overlap with the stepped starting end portion 10a.

Further, as described above, on the inside of the loop-shaped band 10 between the backhawk 3 and the mudguard 5, engaging protrusions 10d that can be press-fitted and locked into the holes 8 of the guard plate 9 are placed at appropriate positions. protrude into the

A bicycle dress guard is constituted by the two guard plates 9 formed as described above and one belt 10 made of an elastic material.

That is, in order to assemble the tress guard of the present invention to a bicycle, the middle part of the band 10 between both curved recessed parts 10b, 10b formed integrally with the band 10 is applied to the upper surface of the mudguard 5 rearward from the back hawk 3, and , the left and right curved concave notches 10b are fitted to the lower parts of the left and right backhawks 3, respectively, to form the band 1.
0 is fixed, and in this state, as shown in FIG. Each of the engagement protrusions 10d is press-fitted into the corresponding hole 8 of the guard plate 9, and the band 10 and the guard plate 9 are coupled as shown on the left side of FIG.

Next, the extended portion of the band 10 is passed through the upper surface of the mudguard 5 in front of the back hawk 3 so that the terminal end 10c of the band 10 overlaps the starting end 10a of the band 10, and the lock provided on the inside of the band 10 is The mating protrusions 10d are press-fitted into the holes 8 of the corresponding guard plates 9 and locked.

Moreover, in order to remove the dress guard of the present invention from the bicycle, the above-mentioned operation may be performed in reverse.

(Effects of the invention) As described above, in the present invention, the bicycle dress guard is composed of two substantially fan-shaped guard plates 9 and one band 10 made of elastic material, so the structure is simple. It also has the advantage of lower manufacturing costs.

In addition, even an amateur can easily assemble and disassemble it, so it can be used when cleaning the inside of the dress guard,
It is very convenient because it can be easily removed when the dress guard is not needed.

Furthermore, since the present invention uses a stretchable elastic band 10 to attach the dress guard to the bicycle, the dress guard can be attached even if the shape and dimensions of the bicycle change considerably. Therefore, the device of the present invention has the advantage that it has a wide range of application, and many excellent practical effects can be obtained according to the present invention.
