Description

[Detailed Description of the Invention] The present invention relates to a turn signal mounting structure for attaching a turn signal body extending outward to the outer surface of a motorcycle body.

The above-mentioned turn signal bodies are generally made of relatively flexible materials such as synthetic resin or rubber, and such turn signals must be firmly attached to the vehicle body, or when external force is applied to the turn signal body. Do not cause damage to the vehicle body when
Although it is required to be lightweight, the above-mentioned conventional turn signal mounting structure has a head part of a mounting bolt b attached to the base end of a turn signal body a made of synthetic resin material, rubber material, etc., as shown in Fig. 3. and a separate positioning knob p is embedded, and the turn signal body a is attached to the vehicle body by the threaded portion of the mounting bolt b and the nut n screwed therein,
In such a conventional type, the bonding strength of the mounting bolt b to the turn signal body a is not sufficient, and the positioning pin p twists or bends against the flexible turn signal body 1, resulting in a slight change in the mounting angle with respect to the vehicle body. In order to prevent this, the part where the mounting bolt connects to the blinker body 1 is made larger and the strength of the connection is increased. However, this approach not only increases the weight of the entire blinker, but also causes the inconvenience of increasing costs.

This idea was made in view of the actual situation,
Provides a motorcycle turn signal mounting structure that increases the strength of the connection between the turn signal body and the mounting bolt without increasing the overall weight of the turn signal, and also prevents damage or deformation of the mounting part on the vehicle body side. The purpose is to

In order to achieve the above object, the present invention includes a mounting bolt whose head is embedded in the base of the turn signal body and whose threaded portion protrudes from the base end surface of the turn signal body; It consists of a metal reinforcing plate buried in the base end of the blinker, and a tightening nut screwed onto the mounting bolt, and the reinforcing plate occupies most of the base end face of the turn signal body and is attached to the outer surface of the vehicle body. and a leg piece that is flat in the vertical direction and is embedded in the turn signal body and extends in the axial direction of the mounting bolt, and the reinforcing plate is in contact with the vehicle body side. The surface is characterized in that a positioning engagement portion is provided on the surface to restrict rotation of the reinforcing plate relative to the vehicle body by engaging with the outer surface.

An embodiment of the present invention will be described below with reference to the drawings.

A turn signal main body 1 is attached to an outer surface 11a of a vehicle body 11 integrated with a fender F and extends outward.
is made of a flexible material such as a synthetic resin material or a rubber material, and a turn signal bulb 2 is provided inside its tip, and this turn signal bulb 2 is covered with a lens 3 fitted to the tip of the turn signal body 1. Ru. Further, an insertion hole 4 is formed in the rod-shaped base of the blinker body 1, through which an electric wire cord 5 connected to the bulb 2 is inserted.

The head 6 of the mounting bolt B is embedded in the base of the turn signal main body 1 during compression or injection molding. The head 6 has a large-diameter flange 6a on its end surface to prevent it from coming off, and a knurl 6 on its outer periphery to increase the strength of the connection with the turn signal main body 1.
b is engraved. A metal reinforcing plate 8 is welded to a stepped portion 6c formed on the head 6 of the mounting bolt B. This reinforcing plate 8 is also buried in the base end portion of the turn signal main body 1 when it is molded, and the outer surface of the plate 8 is exposed to the base end surface 1a of the turn signal main body 1, and is in contact with the vehicle body side, which occupies most of the base end surface 1a. It forms a surface 8c. Further, on the outer surface of the reinforcing plate 8, that is, the abutment surface 8c on the vehicle body side, a knock pin 8a as a positioning engagement portion is integrally stamped and molded, and is further bent at a substantially right angle from both sides to attach the mounting bolt B. A pair of leg pieces 8b, 8 that extend long in the axial direction and are flat in the vertical direction.
b is upright molded, and the leg pieces 8b, 8b are deeply embedded in the turn signal main body 1.

The threaded portion 7 of the mounting bolt B is connected to the turn signal body 1.
It protrudes outward from the base end surface 1a and penetrates the vehicle body 11, and a tightening nut N is screwed onto its tip.

Further, the mounting bolt B is provided with a through hole 9 that communicates with the cord insertion hole 4. The electric wire cord 5 connected to the turn signal bulb 2 is inserted into the cord insertion hole 4.
The cord 5 is pulled out of the blinker body 1 through the through hole 9, and a cord holder 10 provided in the middle of the cord 5 is inserted into the end of the through hole 9 of the mounting bolt B.

A vehicle body 11 in which the turn signal body 1 is integrated with the fender F.
In order to attach it to the outer surface 11a of the
While inserting the knock pin 8a into the vehicle body 11,
After fitting into the pin hole 13 drilled in the hole 13, a tightening nut N is screwed onto the threaded portion 7, and the vehicle body 11 is sandwiched between the nut N and the reinforcing plate 8. As a result, the turn signal main body 1 is firmly fixed to the vehicle body 11.
In this case, the tightening torque of the tightening nut N is transmitted to the reinforcing plate 8 via the knock pin 8a, but this reinforcing plate 8 is integrally connected to the mounting bolt B, and its leg piece 8b is connected to the turn signal body. Since the knob pin 8a is deeply embedded in the turn signal body 1 and strongly connected to the turn signal body 1, there is no twisting or bending of the knob pin 8a, and even if the turn signal body 1 is made of a flexible material, the installation of the turn signal body 1 is easy. There is no need to worry about the angle shifting. Further, since the vehicle body side contact surface 8c of the reinforcing plate 8 is substantially flush with the base end surface 1a of the turn signal main body 1 and occupies most of the base end surface 1a, the surface pressure against the outer surface 11a of the vehicle body 11 is reduced. 11 will not be damaged or deformed.

In particular, the vertically flat leg piece 8 of the reinforcing plate 8
By embedding b into the turn signal main body 1,
The vertical load supporting surface of the reinforcing plate 8 relative to the turn signal body 1 can be ensured to be wider than that in the front-rear direction, and the support rigidity in the vertical direction can be increased. Even when subjected to severe driving vibrations, the turn signal body 1 is stably supported without resonance, and its vibration damping characteristics are improved.On the other hand, the turn signal body 1 has sufficient elasticity in the front and rear direction.
When it receives an external force in the front-rear direction due to contact with another object while traveling, it is appropriately elastically deformed, and the impact caused by the contact etc. can be effectively alleviated.

As described above, according to the present invention, the turn signal body 1 extends outwardly from the outer surface 11a of the vehicle body 11.
The turn signal mounting structure for attaching the turn signal is coupled to a mounting bolt B having a head 6 buried in the base of the turn signal body 1 and a threaded portion 7 protruding from the base end surface 1a of the turn signal body 1. ,
It is composed of a metal reinforcing plate 8 buried in the base end of the turn signal main body 1 and a tightening nut N screwed onto the mounting bolt B. a vehicle body side contact surface 8c that occupies most of the area 1a and can come into contact with the outer surface 11a of the vehicle body 11; A positioning engagement is provided on the vehicle body side abutting surface 8c of the reinforcing plate 8, which can restrict rotation of the reinforcing plate 8 relative to the vehicle body 11 by engaging with the outer surface 11a. Since the joint portion 8a is provided, the mounting bolt B, which is integrated with the reinforcing plate 8, is firmly connected to the turn signal body 1, and even if a tightening torque is applied to the mounting bolt B, the engaging portion 8a will not attach to the turn signal body 1. There is no possibility of it shifting against the
The turn signal main body 1 can be firmly fixed to the vehicle body 11 at a predetermined angle, and the weight of the entire turn signal does not increase significantly. Further, since the outer surface of the metal reinforcing plate 8 forms a vehicle body side contact surface 8c that occupies most of the base end surface 1a of the turn signal main body 1, surface pressure acting on the vehicle body side mounting surface, that is, the outer surface 11a. The outer surface 11a can be removed from the bolt head 6.
It will not be damaged or deformed by.

In particular, a reinforcing plate 8 is embedded in the turn signal main body 1 and extends long in the axial direction of the mounting bolt B.
Since the vertically flat leg piece 8b is provided, by embedding the leg piece 8b in the turn signal body 1, the joint area between the reinforcing plate 8 and the turn signal body 1 increases accordingly, and as a result, the strength can be increased. Furthermore, due to the existence of the leg piece 8b which is flat in the vertical direction, the vertical load supporting surface of the reinforcing plate 8 relative to the turn signal main body 1 is ensured to be wider than that in the front and back direction, thereby increasing the supporting rigidity in the vertical direction. Therefore, even if the turn signal body 1 is subjected to severe vertical vibrations peculiar to two-wheeled vehicles, it is stably supported without resonance and its vibration damping characteristics are improved. Since sufficient elasticity in the direction is ensured, the turn signal body 1 will appropriately deform elastically when it receives an external force in the longitudinal direction due to contact with another object while driving, etc., and effectively absorb the impact caused by the contact etc. can be relaxed.
