[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a steering wheel having a horn button, and more particularly to a steering wheel having a horn button having a good appearance.

[0002]

2. Description of the Related Art Conventionally, a steering wheel having a horn button is provided so that a mating portion between a horn button and a grip portion is made uniform or a pressing member does not interfere with other button peripheral members when the horn button is pressed. A horn button case as shown in FIGS. 5 and 6 was used.

That is, the technique shown in FIGS. 5 and 6 employs a horn button 53 on a grip 52 of a steering wheel 51.
This is an example in which a ring 54 of the grip 52 is formed.
A recess 56 is formed on the spoke 55 formed on the inner side, and a hard horn button case 57 is provided in the recess 56. Arranged
The pressing member 53a is formed on the upper part of the horn plate 58. The horn button case 57 has a guide groove 57a.
Are formed, and the engaging protrusion 53b formed integrally with the pressing member 53a is guided by the guide groove, so that the pressing member 53a slides up and down. In FIG. 5, reference numeral 61 denotes a hopad, and reference numeral 62 denotes a body cover.

A horn button case 5 shown in FIGS. 5 and 6
According to the technique using the horn button case 5, the meat of the open end 56a of the concave portion 56 formed in the grip 52 is
Horn button case 5
The gap between the inside of the upper end of 7 and the pressing member 53a was kept constant, the shape of the fitting portion between the grip 52 and the horn button case 57 could be maintained, and the fitting with the grip 52 was good.

However, the hardness of the horn button case 57 is so large that not only does the horn button case 57 feel uncomfortable with the grip 52 but also the horn button case 57
It is desired that the surface be not exposed from the surface side. Therefore, for example, as shown in FIG. 7, a concave portion 56 is formed in the grip 52, and all of the horn button case 57 is embedded in the concave portion 56. As shown in FIG. Forming the pressing member 53
A technology that does not use a horn button case, in which the horn buttons 53 such as a and the contact 60 are fixed to the spokes 55, and the holes 61a are disposed at the positions of the pressing members 53a and covered with the pads 61, is used.

[0006]

However, the technique shown in FIG. 7 is based on an opening end 56 of a recess 56 formed in the grip 52.
The meat of “a” falls inward toward the concave portion 56, and the pressing member 53a
The clearance between the groove and the opening end 56a of the concave portion 56 is reduced as a whole or becomes non-uniform, which is not preferable in appearance. In the technique shown in FIG. 8, since the pad 61 and the horn button 53 are not in contact with each other, the pad 61 is not uniform when the pad 61 is put thereon, and it is difficult to reliably secure a constant gap. Hole 61 of pad 61
When the gap between the pressing member 53a and the hole 61a of the pad 61 cannot be secured due to the positional error at the time of assembling not only greatly affecting the feel during operation due to the mismatch with a, There is also a disadvantage that the function of the horn button cannot be performed.

SUMMARY OF THE INVENTION An object of the present invention is to provide a steering wheel having a horn button capable of improving the external appearance, increasing the degree of freedom of design, and improving the fit between a grip and a pressing member without exposing the horn button case. To provide.

[0008]

A steering wheel having a horn button according to the present invention includes a horn button having a horn button case, a contact, a spring, a horn plate, and a pressing member. In a steering wheel in which a horn button case is embedded in a grip forming member, an upper end portion of the horn button case is formed as an inclined surface inclined from an outer periphery toward an inner periphery, and is disposed near a surface side of the grip forming member. Configuration.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. The members, arrangements, and the like described below do not limit the present invention, but can be variously modified within the scope of the present invention. FIGS. 1 to 4 show one embodiment of the present invention. A steering wheel 20 having a horn button according to the present invention has a horn button 10 formed on a grip 21 side as shown in FIGS. FIG.

The horn button 10 of the present embodiment includes a grip 21
2 and 4, a horn button case 11 made of a hard resin, and a pressing member 12 arranged on an upper part of the horn button case 11, as shown in FIGS. A horn plate 15 pressed by the pressing member 12, a contact 16 disposed on the horn button case 11 above the spoke portion, and a spring 17 disposed between the contact 16 and the horn plate 15.
And is provided.

As shown in FIG. 3, the horn button case 11 of this embodiment is formed as a hollow box having an open top, and a contact 16 is formed on the bottom 11a so as to protrude into the box. A projection 11c for regulating the spring 17 is formed on the bottom surface 11a around the periphery. A plurality of guide grooves 11b are formed in the inner wall of the horn button case 11 in the up-down direction. The horn button case 11 of the present example has an upper end portion formed as an inclined surface 11d inclined from the outer periphery toward the inner periphery.
The grip forming member is formed at a position near the front surface side.

The pressing member 12 of this embodiment has a pressing portion 12
a is formed, and a receiving surface 12b is formed on a surface (ie, an upper surface) opposite to the pressing portion 12a. Pressing member 1
2 protrudes outward at a predetermined position on the side of the guide groove 1.
An engagement protrusion 12c that engages with 1b is formed. The pressing member 12 is disposed so as to be vertically slidable in the horn button case 11 with the engagement protrusion 12c guided by the guide groove 11b.

As shown in FIG. 3, the horn plate 15 of this embodiment has a projection 15a which contacts the contact 16 and a projection 15a.
And a supporting portion 15b for holding the pressing member 12, and is disposed via a coil spring 17 between the bottom surface 11a and the pressing portion 12a of the pressing member 12. The contact 16 is located on the bottom 1
It comprises a contact plate 16a buried in 1a and a contact projection 16b. In this example, the contact 16
Is configured as described above, but the contacts 16 include all those that conduct between the horn plate 15 and the contact plate 16a.

Reference numeral 31 in FIG. 2 denotes spokes for connecting the grip 21 of the steering wheel 20 to a core (not shown), reference numeral 32 denotes a body cover, and reference numeral 3 denotes a spoke.
3 is a cover pad. Although the coil spring 17 is used in the above embodiment, a leaf spring may be used.

Since the horn button case is not used, unlike the conventional horn button case, it is possible to prevent the grip meat from falling into the concave side when the horn button case is not used, and the horn button case can be seen from the surface. As a result, the appearance is good, and the fitting of the grip and the fitting part of the horn button case becomes easy. In addition, the undercut portion is easily removed during molding, and the grip moldability is improved. In addition, there is less vertical waving, and the grip and horn button case match better.

[0016]

According to the present invention, it is possible to exhibit the same appearance as when the horn button case is not used,
Moreover, it is possible to prevent the meat of the grip at the position where the horn button is provided from falling into the concave side. As described above, it is possible to provide a steering wheel that has a horn button that does not show the horn button, improves the appearance, increases the degree of freedom in design, and has a comfortable sensation without feeling uncomfortable.
