Description

[Detailed Description of the Invention] The present invention relates to a horn mechanism for a steering wheel in which a support body comprising spoke core metals that are coupled to the reinforcing core metal is installed inside a steering wheel body that has a reinforcing core metal inside. .

Generally, in the horn mechanism of this type of steering wheel, as shown in Utility Model Publication No. 53-37388, for example, the horn button for operating the horn is placed on the upper surface of a support provided within the steering wheel body. The button is arranged so as to be movable up and down, and when the button is pressed, the contact point of the horn switch is closed.

By the way, this type of horn mechanism includes, in addition to the so-called button-type horn mechanism shown in the above-mentioned publication, a hinge fitting separately formed on the support so that the cover covering the upper surface of the support can be used as a horn button. At the same time, one end of the cover is fixed to the hinge metal fitting, the cover is swingably supported with respect to the support body, and the horn switch is actuated by swinging the cover. However, in the above structure,
There are problems such as an increase in the number of parts, which requires time and effort to assemble, and a space for arranging the hinge fittings must be secured on the support body.

The present invention was devised in view of the above-mentioned circumstances, and focused on the fact that a reinforcing spoke core metal is provided on the support body, and in order to make effective use of this spoke core metal, A gold piece having a circular cross section is disposed in front of the support body, a horn part is formed to cover the upper surface of the support body, and the horn part is pivotally connected to the spoke core metal so as to be vertically swingable, and , and was supported on the support body via elastic support means.

Embodiments of the present invention will be described below based on the drawings.

In the figure, reference numeral 1 denotes a ring-shaped steering wheel body with a reinforcing core metal 10 therein, and 2 denotes a support body installed on the steering wheel body 1 in the diametrical direction of the wheel body.
A spoke core metal 20 whose both ends are connected to the reinforcing core metal 10 is disposed inside, and an upper end of a steering shaft (not shown) is disposed at the center in the length direction of the support body 2 or the spoke core metal 20. It is designed to connect the parts.

Accordingly, in the present invention, the cross-sectional shape of the spoke core metal 20 is formed into a circular shape, and the spoke core metal 20 is placed at the front side in the support body 2, that is, at the front side in the direction of movement of the automobile, and at the front side of the support body 2. A horn pad 3 is formed to cover the upper surface of the support 2, and this horn pad 3 is pivotally attached to the spoke core 20 so as to be vertically swingable as described later. At the same time, it was supported on the support body 2 via elastic support means.

That is, a support wall 31 extending downward is integrally molded on the lower surface of the front end side of the horn part 3, and an arc-shaped receiving surface 31a having the same curvature as the outer circumferential curvature of the spoke core metal 20 is recessed in the lower surface of the support wall 31. At the same time, a bracket 32 provided with an arcuate hook portion 32a along the outer peripheral surface of the spoke core metal 20 is fixed to the front lower surface of the support wall 31 of the horn pad 3 with a bolt 33.
hook portion 32a and receiving surface 31 of the support wall 31.
sandwich the spoke core metal 20 with a and the core metal 2
The horn pad 3 is pivotably attached to the spoke core metal 20 with 0 as the center of the hinge.

On the other hand, a holding cylinder 34 and a first boss 35 are integrally formed at the rear end of the lower surface of the horn pad 3, and a second boss 36 is formed between the holding cylinder 34 and the support wall 31, respectively.

Then, the first contact plate 4, which has the positive horn cord 41 connected to one end, is connected to the first contact plate 4.
A screw 40 is fixed to the boss 35, and a positive side contact 4 is attached to the other end of the first contact plate 4.
2 is assembled, and the assembled portion of the contactor 42 is held on the lower surface of the holding cylinder 34.

Further, one end of the second contact plate 5 is fixed to the inner surface of the rear wall of the support body 2 with a screw 50,
A negative horn cord 51 is connected to the other end of the plate 5, and a negative contact 52 is attached to the plate 5 at a position facing the positive contact 42.

Further, a through hole 53 is formed in the second contact plate 5, and a coil spring 6 is fitted into the second boss 36, and then the second boss 36 is fitted with a coil spring 6.
6 is inserted into the through hole 53 of the second contact plate 5, and the retaining washer 54 of the plate 5 is fixed to the lower surface of the boss 36 with the screw 55, and the elastic force of the coil spring 6 causes the horn pad to 3 is biased upwardly against the second contact plate 5, in other words, against the support body 2.

Next, the operation of the above embodiment will be explained.

When the horn pad 3 is pressed, the horn pad 3 swings downward using the spoke core metal 20 as a fulcrum against the coil spring 6.
The positive side contact 42 is the negative side contact 52
The horn will sound.

Then, when you stop pushing the horn pad 3, the elastic force of the coil spring 6 immediately causes the horn pad 3 to swing upwards using the spoke core metal 20 as a fulcrum, and the contact 4
2, 52 is released, the horn stops sounding.

As described above, in the present invention, the spoke core bar disposed on the support body has a circular cross section and is disposed in front of the support body, and the horn pad that covers the upper surface of the support body is attached to the spoke core bar. Since the spoke core metal is pivotally mounted to the metal so that it can swing up and down, the spoke core metal can be effectively used as a pivot support member for the support body of the horn pad.Therefore, the number of parts can be reduced accordingly, and ease of assembly is improved. It came to be.
