Description

[Detailed Description of the Invention] This invention relates to a windshield device installed at the front of a so-called open vehicle, such as a motorcycle or a bicycle, which does not have a roof covering the upper part of the seat.

Conventionally, the windshield plate placed at the front of an open vehicle that rectifies the air while driving is hinged to the vehicle body so that it can be folded toward the seat side, and when parked, the windshield plate can be folded toward the seat side to lower the vehicle height. A windshield device is known in which the influence of crosswinds is reduced by doing so, and the upper part of the seat is covered with a folded windshield plate to prevent the seat from getting wet due to rain or the like when parking the vehicle.

Figures 1 to 3 show conventional examples of such windshield devices, in which 1 is a transparent synthetic resin windshield plate, 2 is a hinge that connects this windshield plate 1 to the vehicle body 3 of an open vehicle. , 4 is a steering wheel, and 5 is a seat.

The hinge 2 includes two hinges that are pin-coupled to each other on the same axis.
One side 2a of the main pipe is fixed to the windshield plate 1, and the other side 2b
is inserted into a support pipe 3a fixed to the vehicle body 3, and when the bottle coupling part 2c is extracted from the support pipe 3a, the windshield plate 1 can be folded toward the seat 5 side.

By the way, in the case where the windshield plate 1 is rotatably attached to the vehicle body 3 simply using a hinge as described above, the height dimension H of the windshield plate 1 is determined from the distance from the center of rotation of the hinge to the rear of the seat 5. If it's not big enough, it won't be able to cover seat 5.

Therefore, in order to prevent the seat 5 from getting wet due to rain etc. when parking, the dimensions of the windshield plate 1 must be made larger than necessary compared to the size required for the original windproof function during driving. There was a problem.

The present invention was proposed to solve the above problem, and by devising the connection structure of the windshield plate to the vehicle body, it is possible to prevent the seats from getting wet during parking even if the windshield plate is not very large. The purpose is to provide equipment.

Hereinafter, this invention will be explained based on an embodiment shown in FIGS. 4 to 6.

In this embodiment, a motorcycle is selected as the open vehicle.

In these figures, what is indicated by the symbol A is a windshield device.

This windshield device A includes a transparent synthetic resin windshield plate 11 arranged in front of a handlebar 10a of a motorcycle to rectify the air during riding, and a windshield plate 11 made of transparent synthetic resin that is arranged in front of a handlebar 10a of a motorcycle to rectify the air during riding. The connecting device 12 is connected to a nearby vehicle body 10c.

The connection device 12 includes a connection auxiliary fitting 13 fixed to the lower end of the windbreak plate 11, and a support fitting 14 fixed to the vehicle body 10c and detachably supporting the windbreak plate 11 via the connection auxiliary fitting 13.

It consists of 6.

The connecting auxiliary fitting 13 has leg portions 13a, 13a formed on both sides of the windbreak plate 11 in the width direction.

These leg portions 13a are formed with a fitting protrusion 13b protruding forward at the front (front in FIG. 6) lower end thereof, and above the fitting protrusion 13b is a connecting pin having a screw portion formed at the tip. An insertion hole 13c is formed through which the knob 17 is inserted, and a female threaded portion 13d is formed on the rear side surface thereof to be threadedly engaged with the threaded portion of the knob 18, which has a shaft portion 18a with a threaded portion formed at the tip.

The support fittings 14 are two arms that are fixed via bolts 19 to the lower side of the vehicle body 10c, which extends from the lower side of the handle 10a toward the front of the handle. portion 14a, a side wall portion 14b rising from the middle of each arm portion 14a and fixed to the upper side of the vehicle body 10c via bolts, etc., and a side wall portion 14b provided on each arm portion 14a are connected to each other and the side wall portion 14b is fixed to the upper side of the vehicle body 10c. A bridge portion 14c fixed to the front surface of the arm portion 10c via a bolt 20 is integrally formed, and a fitting protrusion formed on the leg portion 13a of the connection auxiliary fitting 13 is provided at the tip of the arm portion 14a. A fitting hole 14d into which the fitting 13b is fitted is formed.

Further, the side wall portion 14b forms a wall portion facing the inner side of the leg portion 13a, and the position corresponding to the female screw portion 13d formed on the leg portion 13a on the rear end side of the side wall portion 14b is A female threaded portion 14e is formed to engage with the threaded portion of the knob 18, and below the female threaded portion 14e is the link 1.
A link support hole 14f is formed through one end of the link support hole 5 in a rotatable manner.

The links 15 are connected to the connecting auxiliary fittings 13 that are paired with each other.
It is formed into a substantially crank shape by two connecting rods 15a that connect the leg portions 13a and the side wall portions 14b of the support metal fitting 14, and a connecting rod 15b that connects these connecting rods 15a with each other.

A rotating shaft 15c is formed at one end of the connecting rod 15a, protruding in the width direction of the windshield plate 11, and rotatably passing through the link support hole 14f of the support fitting 14. On the tip side, the rotation shaft 15C is connected to the link support hole 1.
Retaining ring 2 such as E-ring to prevent it from being removed from 4f
A groove 15d into which 1 is fitted is provided around the periphery.

Further, the other end of the connecting rod 15a is formed with a female threaded portion 15e that engages with a threaded portion formed at the tip of the connecting pin 17, and the connecting pin 17 passes through the insertion hole 13c of the auxiliary connecting fitting 13. The other end of the connecting rod 15a and the front end side of the auxiliary connection fitting 13 are rotatably connected to each other via the connecting rod 15a.

The windshield plate 11 includes a connecting auxiliary fitting 13 and a supporting fitting 14.
The connecting rod 15a of the link 15 is connected to the vehicle body 10c so as to be rotatable around the link support hole 14f with a radius L□ along the longitudinal direction of the vehicle body. Fit the fitting protrusion 13b formed on the leg 13a of the auxiliary fitting 13 into the fitting hole 14d formed on the arm 14a of the support fitting 14, and then adjust the position of the female threaded portion 13d of the leg 13a to the fitting hole 14d of the support fitting 14. The knob 18 is firmly fixed to the vehicle body 10c by aligning it with the female threaded portion 14e of the side wall portion 14b, and then screwing the threaded portion of the knob 18 through the female threaded portion 13d into the female threaded portion 14e.

In addition, in order to release the fixation of the windshield plate 11, it is sufficient to perform the above-mentioned fixing work in the reverse order.If the fixation of the windshield plate 11 is released when parking, the windshield plate 11 will extend the length of the link 15 into a radius. seat 10 by rotating around one end of link 15 as
It can be folded towards the seat 10b side, and when it is folded towards the seat 10b side, the moving distance towards the seat 10b side increases by the length of the link 15.

Therefore, the size of the windshield plate 11 is smaller than that of a conventional windshield device in which the windshield plate is simply connected to the vehicle body with a hinge.
There is no need to make the distance larger than the distance from the mounting position of No. 1 to the rear of the seat 10b.

That is, as long as the size of the windshield plate 11 is made slightly larger than the size of the seat 10b, the upper part of the seat 10b can be covered with the windshield plate 11 by adjusting the effective length of the link 15. Seat 1 due to rain etc. when parking
Wetting of 0b can be prevented.

Note that the arm portion 14a is attached to the lower end of the leg portion 13a.
A buffer rubber 22 is attached that comes into contact with a part of.

This buffer rubber 22 absorbs the looseness between the connecting auxiliary metal fitting 13 and the supporting metal fitting 14 when they are fixed, and alleviates the impact force generated between the two during driving or the like.

As explained above, the windshield device of the present invention is a windshield device that is connected to the vehicle body so that the windshield board provided at the front part of the vehicle body of an open vehicle can be folded toward the seat side. The metal fittings are removably fixed to the support metal fittings fixed to the handlebar, and the connecting auxiliary metal fittings and the support metal fittings are connected around an axis in the vehicle width direction, with the front end attached to the connection auxiliary fitting and the rear end attached to the support metal fittings. Since the windshield is connected by a link that is rotatably connected to the windshield, the distance that the windshield can move toward the seat side increases by the length of the link.

Therefore, by adjusting the effective length of the link, the upper part of the seat can be covered with the windshield without making the windshield larger than necessary, and the seat can be prevented from getting wet due to rain when parking.

In addition, when the windshield is tilted backwards, the link functions as a positioning member that increases the distance the windshield can move backwards while maintaining connection with the support metal fittings, and supports the windshield instead of being a strength member. Since it is provided separately from the structure, the structure is simple and lightweight.

Furthermore, the joint between the windshield side and the link is mutually rotatable, which prevents unnecessary angular restraint when the windshield is tilted backwards, and therefore prevents the windshield from moving backwards. The distance can be easily and sufficiently increased, and the shape and size of the seat portion can be easily accommodated or adapted to the seat.

Also, when the windshield plate is upright, the link can hold the force that acts in the longitudinal direction of the link, so
In this sense, it functions as a reinforcement for the connection between the auxiliary connection fitting and the support fitting, and the overall structure for obtaining the strength of the connection is efficient.
