Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a windshield device attached to the front portion of a motorcycle.

(Prior art) Generally, a windshield device attached to the front of a motorcycle has a structure in which a transparent window that allows the front to be seen through is attached to the upper front of a cowling that is attached to the vehicle body. In this case, if connecting members such as bolts are visible from the outside at the joint between the cowling part and the window part, the appearance will be poor and the product value will be reduced.

As a countermeasure for this, there is a method in which the head of the connecting bolt is embedded in the cowling part, the threaded part is made to protrude to the back side, and the edge of the window part is tightened and fixed to this threaded part with a nand.

However, although this connection structure makes it possible to make the bolt head invisible, the molding process is complicated because the bolt head is embedded in the cowling part, and the mold cost for molding is high. There are drawbacks that make it unavoidable. In addition, since the part where the bolt head is embedded needs to be made of III-thickness, the difference in shrinkage between this thick part and other thin parts creates a dent called a "sink mark" in the thick part. There are also drawbacks.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide a windshield device for a motorcycle in which the head of the connecting bolt is not visible and can be easily cut out, and which does not cause sink marks due to differences in wall thickness. .

[Structure of the invention]

To achieve the above object, the present invention provides a windshield device for a motorcycle comprising a cowling section attached to the front part of the vehicle body and a transparent window section attached to the front upper part of the cowling section. A contact edge that contacts each other on the front side of the cowling part is formed, a retaining part is formed on the back side of the contact edge of the cowling part, and a retaining part is formed on the contact edge of the window part that contacts each other. forming a tongue piece extending to the lower side of the part;
The present invention is characterized in that the head of the bolt, which is engaged with the tongue portion, is engaged with the retaining portion and is then tightened and fixed together.

〔Example〕

The present invention will be explained below with reference to embodiments shown in the drawings.

FIG. 3 shows the main parts of a motorcycle equipped with a windshield device according to the present invention, in which 1.1 is a front fork provided at the front of the vehicle body, and 2 is a handle.

A headlamp 3 is attached to the upper part of the front forks 1, 1, and a windshield device 4 is attached so as to cover the outside thereof. This windshield device 4 is composed of a resin cowling part 5 attached to the vehicle body and a transparent resin window part 6 attached to the front upper part of this cowling part 5, and the front can be seen through this window part 6. It is now possible to do so.

The joining structure between the cowling part 5 and the window part 6 is as shown in FIGS. 1A and B at the center of the front, and there are two structures on both left and right sides as shown in FIGS. 2A and B. Each is provided separately.

In any of the above locations, the cowling portion 5 and the window portion 6 have contact edges 7° 8 that abut against each other on their front surfaces.

On the cowling part 5 side, a bag-shaped retaining part 9 with one end open is formed on the back side of the abutting edge part 7, and this engaging part 9 is cut inward from the open end. A missing guide groove 9a is provided. Also, on the window portion 6 side, there is a contact edge 8.
A tongue piece part 10 is formed which extends further inward from the above-mentioned retaining part 9 and extends downwardly from the retaining part 9.

When joining the two in such a joining structure, the connecting bolt 11 is locked to the tongue piece 10, and the bolt head is guided while the threaded part 1-11 of the bolt 1-11 is guided into the guide groove 9a. 11h into the bag-shaped engaging portion 9, the abutment edges 7.8 are brought into close contact with each other, and in this state, the nand 12 is tightened and fixed.

According to the windshield device 4 described above, the head 11h of the bolt 11
Since it is hidden by the bag-like retaining part 9 of the cowling part 7, the pole 11 is not visible from the outside.

Moreover, the head 11h of the bolt 11 is not embedded in the cowling part 7 as in the conventional case, but is engaged with the retaining part 9 formed on the back side of the abutting edge part 7, so that the head part 11h is molded. Cutting out the mold at the time can be done easily by pulling it out toward the opening side of the retaining part 9. Therefore, unlike the case of embedding a bolt head, mold cutting is not complicated.

Further, since there is no need to form a thick part unlike when a bolt head is embedded, so-called sink marks (recesses) due to differential shrinkage do not occur.

〔Effect of the invention〕

As described above, the present invention provides a windshield device for a motorcycle comprising a cowling section attached to the front part of the vehicle body and a transparent window section attached to the front upper part of the cowling section. Abutting edges that abut each other on the front side of the cowling part are formed, a retaining part is formed on the back side of the abutting edge of the cowling part, and an engaging part of the cowling part is formed in the abutting edge of the window part. A tongue piece portion extending downwardly is formed, and the head of the bolt, which is engaged with the tongue piece portion, is secured to the engaging portion and then tightened and fixed together. Therefore, the connecting bolt is hidden on the back side of the cowling part and cannot be seen, but unlike conventional methods, the bolt head is not integrally molded, making it easier to cut out the mold and forming a thick wall part. Since it is not necessary, it does not cause sink marks.
