DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure for a windshield provided in front of an occupant of a motorcycle.

[0002]

2. Description of the Related Art An example of a conventional windshield mounting structure is shown in FIG. This figure is a view showing the windshield assembly in which the rear side (occupant side) of the windshield 1 is attached to the support member 2 from the rear side (occupant side). The support member 2 has a substantially L-shape in side view. It is installed as a pair on the left and right sides.

The supporting member 2 is composed of a round bar-shaped vertical portion 5 connected by bolts 3 and nuts 4 and a plate-shaped horizontal portion 6 formed by pressing. The horizontal portion 6 has a mounting seat for the vehicle body. 7 is provided, and is attached to the vehicle body by a mounting leg screw (not shown) of a rearview mirror (not shown) passed through a through hole 8 formed here.

[0004]

By the way, the supporting member 2
Is formed in a substantially L-shape because, when an excessive force is applied to the windshield 1, stress concentration is absorbed by deformation of the vertical portion 5 and the horizontal portion 6, and damage to the expensive windshield 10 is prevented. It is in.

Therefore, it is not sufficient that the lateral portion 6 is unnecessarily high in rigidity. Conversely, if the rigidity is increased more than necessary, the weight increases and the mounting portion of the windshield 1 to the support member 2 is easily damaged. There are cases.

[0006] In addition, in the case of the above structure, the lateral portion 6
Terminal processing to make the end face of the R-shaped may be required,
In order to cope with this, it is troublesome to process and form the plate-shaped member in which the lateral portion 6 is press-formed as in the related art.

On the other hand, it is conceivable that the entire support member 2 is formed of a large-diameter round bar-shaped member, and the mounting seat portion is flattened. However, in this case, the mounting seat portion is weakened, so that the whole is formed of a considerably thick material, which increases the weight and the cost.

[0008]

In order to solve the above-mentioned problems, a windshield mounting structure according to the present invention is provided with a support member having a substantially L-shape in side view for supporting a rear side of the windshield. The member includes a vertical portion extending substantially vertically and supporting an intermediate portion of the windshield at the upper end, and a horizontal portion extending forward from the lower end of the vertical portion and supporting the lower portion of the windshield at the front end. In the windshield mounting structure in which a mounting seat for mounting the support member to the vehicle body is provided in the lateral portion, the vertical portion and the horizontal portion are formed by a single continuous member, Is outward in a substantially U-shape in plan view
By protruding a bent portion, by welding the periphery of the mounting seat formed from a separate plate-shaped piece to the inner surface of the bent portion , at least the outer end surface and the rear end surface of the mounting seat at the bent portion are welded. the circumference Mutotomoni, Bakkumira the mounting seat
It is characterized in that it is shared with the mounting part of

[0009]

Since the mounting seat is surrounded by the bent portion in the lateral direction, the mounting seat is reinforced by the bent portion, and the mounting seat integrated with the bent portion is required to be mounted on the vehicle body. A sufficient degree of strength. Therefore, since the mounting seat itself can be a relatively thin plate-like member, it is possible to prevent an increase in overall weight and an increase in cost. In addition, it can be used for the mounting part of the rearview mirror.

Further, even in a case where an R-shaped terminal treatment is required for the end surface of the mounting seat, at least the outer end surface and the rear end surface of the mounting seat are surrounded by a bent portion. They do n’t expose in these directions.
Then, since the bent portion serves as a rim member to improve the appearance, the terminal treatment for these portions can be omitted. In addition, the labor of processing and molding is reduced.

[0011]

An embodiment will be described below with reference to the drawings. 1 is a view corresponding to FIG. 5 showing the windshield assembly from the occupant side, FIG. 2 is an exploded perspective view of the windshield assembly, FIG. 3 is a plan view of the material, FIG.
Is a side view of the same.

The windshield assembly is a small assembly composed of the windshield 10 and the support member 20, and the support member 20 is substantially L in side view.
Character-shaped round bar-shaped member 30 and a flat, substantially oblong mounting seat 4
0 is provided.

The round bar-shaped member 30 has a vertically extending portion 31 extending vertically and a lateral portion 32 extending substantially horizontally in the front-rear direction, and is formed integrally and continuously. The lateral portion 32 is a lower end of the vertically extending portion 31 in side view. A bent portion extends substantially horizontally forward from the portion and projects outward in a substantially U-shape in plan view.

The upper end of the vertical portion 31 forms a mounting portion 33 which is bent forward, and a female screw portion 34 is formed at the axial center of the tip. The mounting portion 33 is provided at the center hole 5 of the vibration isolating rubber 50 mounted at the middle part in the vertical direction on both the left and right sides of the windshield 10.
1 is connected to the windshield 10 by screwing a screw 53 to the female screw portion 34 from the front of the windshield 10 via a washer 52.

The end of the lateral portion 32 forms a flatly crushed mounting portion 35, and a through hole 36 provided therein is
The windshield 10 is connected to the center hole 55 of the vibration isolating rubber 54 provided on the left and right sides of the lower portion of the windshield 10 by fastening with screws 56 and nuts 57.

The mounting seat 40 is formed by cutting an iron plate, which is much thinner than the diameter of the round bar-shaped member 30, into a predetermined shape by pressing, and the size thereof is a space surrounding the bent portion 32 in a U-shape. 37 (see FIG. 2).

A part of the front end face 41, the outer end face 42 and the rear end face 43 of the mounting seat 40 are welded to the side faces (hereinafter referred to as the inner side faces) facing the space 37 of the lateral part 32 which is a bent part. Is the horizontal portion 3 as is apparent in FIG.
2 so as not to be exposed to the outside in a side view and a rear view shown from the occupant side.

As apparent from FIG. 3, the front end face 4
1 and the outer end surface 42, a corner portion 44a, the outer end surface 42
Corner portion 44b of rear end surface 43 and rear end surface 43
A gap 46 is formed between the corner portion 44 c of the inner end surface 45 and the lateral portion 32.

Two mounting holes 47, 48 are formed in the center of the mounting seat 40 in the front-rear direction. As is apparent from FIG. 2, the front mounting hole 47 is for mounting a rearview mirror 60, and a mounting leg 62 with a male screw formed at the lower end of the stay 61 is inserted into the mounting hole 47 and fixed with a nut 63 from below. It is supposed to.

The rear mounting hole 48 is used for mounting the vehicle body. The bolt 21 passed through the mounting hole 48 is fastened to an appropriate place on the vehicle body (not shown) via the collar 22 so that the windshield assembly can be mounted on the vehicle body. It has become.

Next, the operation of the present embodiment will be described. Since the lateral portion 32 of the round bar-shaped member 30 is a bent portion, the windshield 10
When excessive force is applied, stress concentrates on the lateral portion 32,
Since the lateral portion 32 deforms first before the windshield 10 is damaged, it becomes easier to absorb excessive force applied to the windshield.

For this reason, the occurrence of a case where the expensive windshield 10 is replaced is prevented as much as possible. In many cases, only the relatively inexpensive support member 20 needs to be replaced, so that the economical burden can be reduced.

Further, since the mounting seat 40 surrounds the end face seen from the outside and the rear by the lateral portion 32, it is not exposed to the outside in these directions, so that the terminal treatment becomes unnecessary, so that the manufacturing cost can be reduced. . In addition, processing and molding can be reduced.

Further, by welding the mounting seat 40 to the lateral portion 32 surrounding the periphery, the mounting strength to the vehicle body is reinforced by the lateral portion 32, so that the mounting seat 40 itself can be formed of a relatively thin material. Therefore, it can contribute to weight reduction.

Moreover, the corners 44a of the mounting seat 40,
Since the gap 46 is provided between the corner portion 44b, the corner portion 44c, and the lateral portion 32, even if the dimensional accuracy of the mounting seat 40 is slightly deviated, welding can be performed to the lateral portion 32, so that workability is improved.
