Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in blinker devices for motorcycles and the like.

The motorcycle is preferably provided with blinkers on both front and rear sides for direction indication, and the blinkers are preferably provided so as to protrude outward to improve visibility.

In order to provide such blinkers protruding from both sides of the vehicle body, the blinkers are generally provided so as to protrude in the width direction through stays, and since the stays and blinkers protrude outward, they become one of the elements of resistance during high-speed driving.

The present invention has been made in view of the above, and its purpose is to improve the aerodynamic characteristics during high-speed running, reduce running resistance, and reduce output power. An object of the present invention is to provide a blinker device for a motorcycle or the like that can be used in a motorcycle or the like.

Next, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a schematic side view of a motorcycle 1, in which a front fork 4 that supports a front wheel 5 is supported by an upper and lower bridge 6.6 through a helad tube 3 at the front end of a frame 2 so as to be freely steerable. A handle 7 is installed on the top bridge, a fuel tank 8 is mounted on the front of the frame 2, a seat 9 is mounted behind this, and an engine 10 is mounted on the front lower part of the frame 2. In this embodiment, the engine 10 is a horizontal V-type water-cooled engine with a horizontally placed crankshaft, a down tube 2 a J two parts K of the frame 2, a lower hull split type radiator 11, and an under cowl 12 at the bottom. A lower radiator (not shown) is provided, which is surrounded by a lower radiator. A rear fork 13 that supports the rear wheel 14 is pivotally extended from the rear lower part of the frame, and in the figure, 15 indicates a seat cowl, 16 indicates a fairing provided at the front of the vehicle body, and 17 indicates a rearview mirror. .

A blinker device is provided at the front and rear of the above motorcycle.

The front blinker 18 is the front fork 4 in the embodiment.
A base is attached to and supported by the left and right upper members 4a, 4a of the base, and is provided so as to protrude outward from each side. Details of the blinker are shown in Figures 4 to 7, and Figures 5 and 6 are shown in Figure 4.
The state seen from the side is shown in the arrow 5 direction and the 6-6 line sectional view of the drawing plane.

The turn signal 18 includes a base 19, a lens 20 and a stay 21.
The lens 20 is fitted onto the opening edge 19a of the base 19 and formed into a teardrop shape on the side. The outer surface of the lens 20 has an arc with a large radius at the tip 20a, and an inflected arc shape on the side. In the base 19, the top and bottom of the front part 19b are continuous with the top and bottom of the rear part 20b of the lens 20 with an arc, and further, the vertical dimension gradually decreases toward the rear like the half-rest of an egg, and the rear end 19d of the rear part 19C is a large arc. The side surface as a whole has a teardrop shape, and the plane surface has a shape similar to that of a teardrop as shown in FIG.

The blinker base 19 extends to one side.
and a stay 21 connected thereto, the stay part 19
e and the stay 21 have the same cross section, and extend to one side of the base so as to form a small teardrop shape similar to the shape of a teardrop consisting of the base 19 and the lens 20, as shown in FIGS. 5 and 6. There is.

A set of symmetrical blinkers 18 is prepared, and in the embodiment, the stay 21 is connected to the left and right front fork upper members 4.
The lenses 20 and base 19 at the tips of the stays 21 are mounted and supported by the stays 21 while being spaced apart from the outside of the upper members 4a and 4a. becomes.

FIG. 7 shows a cross-sectional plan view of the blinker 18, and the base 1
The bulb 23 is set in the socket 22 provided in the socket 22, the back side of the bulb 23 is surrounded by a reflector 24, and the wire is connected with a no-nest 25 passing through the stay part 19e and the inside of the stay 21. A mounting bolt 26 is buried so as to protrude outward.

Such specific internal structure is arbitrary.

Rear blinkers 27, 27 are provided at the rear of the motorcycle 1 via stays 29 protruding from the left and right sides of the rear of the vehicle body, and the lenses 28 face rearward.
9 also has a teardrop shape similar to the above.

In the above embodiment, the front turn signal is attached and supported on the front fork, but it may be attached and supported on the frame, and the specific attachment location of the rear turn signal is arbitrary.

8 to 10 show a specific mounting structure of the blinker 18.

FIG. 8 shows the stay 1 that supports the base 19 and the lens 20.
A missing circular mounting part 122 is provided at the base of the mounting part 1.
Tightening pieces 124 protrude outward on both sides of the entry part 123 of 22.
．． 125 is provided, a screw collar 126 and a collar 127 are buried in one of these, and a fork pipe 4a forming a small diameter upper cylindrical member of the front fork 4, for example, is fitted into the fork part 122 and tightened with a bolt 128 or the like. Piece 124.12
5. Tighten and connect the coupler part 122 to the fork pipe 4a.
It concludes to. Each part of the above mounting part 122 and the stay 121
It is integrally molded from synthetic resin, rubber, etc., and unlike metal, it has a certain degree of elasticity, so it can provide vibration-proofing and shock-absorbing effects.

In FIG. 9, a semicircular mounting portion 222 is provided at the base of the stay 221, and tightening pieces 223 and 222 are provided on the outside of the end of the mounting portion 222.
For example, apply this to the half circumference of the fork pipe 4a,
On the other hand, prepare a semicircular bracket 225, apply it to the remaining half of the fork pipe, apply the clamping parts 226, 227 protruding on both sides to the clamping pieces 223, 224, and fasten with bolts 228. In this case, the base 222 is attached to the stay 2.
21 shall be molded integrally with synthetic resin, rubber, etc.
Similar to the above, vibration damping and shock absorbing effects can be obtained.

In FIG. 10, a planar U-shaped bracket 321 is prepared, the inner base 322 of which is semicircular, and the fork pipe 4a is exposed to the base 322 between the mounting pieces 323 and 324 that protrude from the base on both sides. , 324, and a bolt 328 is inserted between the end of the mounting piece and the spacer to connect the spacer. Four arcuate portions 326 are provided at the portion of the spacer 325 that contacts the circumference of the fork pipe to serve as a core. A positioning protrusion 327 is provided on the outer end of the spacer 325, and the bracket 325 is molded separately from the turn signal and its stay, and the turn signal stay is attached to the bracket using a threaded portion provided on the stay. Link.

As is clear from the above, according to the present invention, in the blinkers of motorcycles, etc., the blinkers and stays are shaped like teardrops, which improves aerodynamic characteristics especially during high-speed running, reduces running resistance, and reduces output during high-speed running. It is possible to suppress the loss as much as possible, and it has many advantages such as improving fuel efficiency during high-speed driving.
