Description

[Detailed Description of the Invention] The present invention relates to a direction indicator light for a two-wheeled vehicle having a stay made of a rubber-like elastic body.

Turn signal lights equipped with this type of stay are well known, but they have mounting bolts inserted at both ends of the stay 0. Especially when connecting to a lamp housing, after inserting the mounting bolts into the holes in the lamp housing, It is tightened and fixed by screwing together the washer and nut.

However, since these washers and nuts are tightened inside a narrow housing, it is difficult for the tightening tool to enter, making tightening work extremely difficult.If the tightening is not secure, they may loosen due to vibration and lack stability. There are drawbacks.

The present invention has been made to eliminate these drawbacks, and its purpose is to provide a direction indicator light for two-wheeled vehicles that is simple in construction, easy to assemble, and can be installed in a stable manner. It is something to do.

The present invention, which was developed to achieve this purpose, consists of a stay made of a rubber-like elastic body and a lamp nozzle, and a mounting bolt is embedded in the base of the stay, and the head is connected to the head via the neck. The ramp nose housing has a hole into which the wing fits, and an engagement mechanism that engages with the wing, and the forcible engagement between the wing and the engagement mechanism causes the stay to be fixed. A direction indicator light for a two-wheeled vehicle, characterized in that the lamp housing and the lamp housing are connected to each other with restricted rotation, and when the lamp housing and the stay are installed, the blade of the stay is inserted into the hole of the lamp housing. The wing portion and the engagement mechanism are engaged by simply inserting the portion and rotating it in the right or left direction, which stabilizes the attachment state and facilitates the connection and engagement operation.

Next, the present invention will be explained in more detail with reference to the illustrated embodiment. In the first embodiment shown in FIGS. It is something that will be done.

The lamp housing 1 has a plurality of protrusions 11 formed therein, a base plate 12 is attached to the protrusions, a socket 13 is fixed to the base plate, and a light source 14 is attached to the socket.

The lens 15 is attached to the opening side of the lamp housing 1, and the structure up to this point is the same as the conventional example.

One side of this lamp housing (bottom in the diagram)
A cylindrical hole 16 is formed in the cylindrical hole 16, and an engagement mechanism is formed so that the end faces the edge of the hole.

This engagement mechanism is composed of a rotational direction stopper piece 17 and a return prevention stopper piece 18.The rotational direction stopper piece 17 is formed relatively high in height, and the return prevention stopper piece 18 is formed low and has one side. It is formed on the tapered surface 18a so that the wing portion described later can easily ride on it.

As shown in FIG. 3, the stay 2 is a rubber-like elastic body made of a polymer material such as polyurethane elastomer and formed into a rod shape, and has a bolt 21 at one end, that is, the base side, for attachment to the vehicle body. It is integrally formed by insert molding, and an insertion hole 22 for the cord 3 is provided in the shaft core.

A shoulder portion 23 is formed on the head side of the stay 2, that is, the side where it is attached to the lamp housing, and a wing portion 25 is formed through the neck portion 24.
are integrally formed, and a notch 26 is formed in a part of the lower surface of the wing.

When the lamp housing 1 and the stay 2 are assembled, the stay 2 is inserted into the hole 16 of the lamp housing 1 from the head side, that is, from the wing part 25 to the neck part 24, and the stay 2 is inserted as shown in FIG. When rotated to the left as shown by arrow a, the wing portion 25 on the side where the cutout portion 26 is formed aligns with the tapered surface 18.
It climbs over the return prevention stopper piece 18 along the direction a and comes into contact with the rotational direction stopper piece 17.

At this position, the return prevention stopper piece 18 fits into the notch 26 and serves as a stopper against rotation in the return direction.

In this case, even if there is rotation in the return direction, the return prevention stopper piece 18 has no tapered surface in the return direction, so it is difficult to get over it, and the engaged state is stabilized (see FIG. 5).

In the second embodiment shown in FIGS. 6 to 8, the only changes are that the stay 2 is square and the shape of the engagement mechanism is changed; other parts have the same structure and are given the same reference numerals and their explanation will be omitted. do.

The stay 2 of the second embodiment is formed into a rectangular shape, and the stay 2 is gripped to provide a large rotational force when engaged with the lamp housing 1.

One end of the wing portion 25 formed on the head side of the stay 2 is not cut into a cylindrical shape, but one corner portion is left protruding to form an engaging end portion 25a.

The hole 16 of the lamp housing 1 into which the wing part fits is also formed to match the shape of the hole 16, and the engagement mechanism is formed so that the end faces the edge of the hole 16.

The engagement mechanism is also formed by a rotation direction stopper piece 17 and a return prevention stopper piece 18, the height of both stopper pieces being the same, and only the length and the space between them being changed.

That is, the return prevention stopper piece 18 is formed shorter than the rotation direction stopper piece 17, and the space between them is the same as the wing part 25.
It's wide enough to fit in.

With this configuration, when the wing section 25 is inserted into the hole 16 of the lamp housing 1 and the stay 2 is rotated in the direction shown by the arrow a in FIG. Two corner parts have easy return prevention stoppers 1
8, but since the engaging end 25a of the other corner protrudes, it is difficult to pass through.

If the stay is further forcibly rotated, since the material of the wing part is a rubber-like elastic body, it deforms and passes.

When the wing comes into contact with the rotational direction stopper piece 17, the wing fits between the two stopper pieces and is seated, making it stable.

In any of the embodiments, the stay is inserted into the hole of the lamp housing and forcibly rotated in a predetermined direction, whereby rotation and return are suppressed by engagement between the engagement mechanism and the wing section.
The wall portion of the lamp housing is held between the wing portion and the shoulder portion, and the stay and the lamp housing are connected to each other.

As explained above, in the motorcycle turn signal light according to the present invention, when the separately formed lamp housing and the stay are connected, it is extremely easy to connect and fix the lamp housing and the stay by connecting the blade and the engagement mechanism. Unlike tightening washers and nuts in a narrow space such as in a small space, it is simply screwed in, making the connection and fixing work extremely easy, and the connection is secure and does not loosen due to vibration etc., making it extremely stable. It has an excellent effect.

Furthermore, in the structure of the stay, the neck and the wings are integrally formed on the head side, and in the structure of the lamp housing, only the hole and the engagement mechanism are formed, which simplifies the structure. At the same time, heavy metals such as mounting bolts, washers, and nuts can be omitted, and the overall weight of the lamp can be reduced.
