Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a steering wheel used for steering a vehicle, for example, and uses reinforced plywood in the spokes to improve appearance, productivity and durability. It is a thing.

[0002]

2. Description of the Related Art Conventionally, in this type of steering wheel for automobiles, so-called steering wheel, a metal such as aluminum or aluminum alloy or a synthetic resin is used as a material of a spoke portion connecting a rim portion and a hub portion. those that have been coated, or etc. to a metal core of <br/> those bonded skin wound or wood is used.

[0003]

However, in the steering having the conventional structure as described above, there are almost no problems relating to the strength problem, but the appearance concerning the user's taste such as high-class feeling and warmth is poor.

[0004] In particular, in the spoke portion having a structure in which wood is attached to a metal core, since a solid wood cut-out material is used as the wood, the surface is rough and lacks in smartness, resulting in poor design. Not only is it poor, but it is also inferior in productivity, and moreover, it is prone to cracks and the like and has poor durability.

[0005]

SUMMARY OF THE INVENTION An object of the present invention is to provide a steering wheel for an automobile or the like which can improve the appearance, productivity and durability of the spokes.

[0006]

In order to solve the above problems SUMMARY OF THE INVENTION This invention comprises a spoke portion connecting the rim portion and the hub portion, the spoke portion, at least on the surface of
It consists of a laminated member consisting of a core veneer laminated with decorative veneers and a reinforcing core material.
It is made of reinforced plywood.

[0007] In this case, the reinforcing core material of the laminated member, sheet metal such as aluminum or an aluminum alloy, or be a fiber-reinforced plastic plate material preferred.

[0008]

[For work] Namely, the present invention is a spoke portion which <br/> connecting the rim portion and the hub portion, the laminated member of the core veneer and the reinforcing core material
To become formed by reinforced plywood consisting, the productivity is enhanced by plywood structure of the spokes, sheet metal such as aluminum or an aluminum alloy, or thinned by lamination of the reinforcing core material made of a fiber reinforced plastic plate Also has sufficient strength, which can improve the durability.

Further , various decorative wood veneers can be used as a decorative veneer on the surface.
Since it is possible to use plates
The appearance can be improved with a stylish design .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a plan view of a steering wheel of an automobile or the like according to the present invention, in which 1 is a ring-shaped rim portion, 2 is a hub portion,
Reference numeral 3 is a T-shaped spoke portion.

The spoke portion 3 is, as shown in FIG.
The rim portion 1 and the hub portion 2 are separately connected.

Further, the rim portion 1 and the spoke portion 3 are
As shown in FIG. 3, a metal core 11 made of an iron core of the rim portion 1
The ends 3a of the spokes 3 are connected to each other by fastening with bolts 4.

The spoke portion 3 is, as shown in FIG.
Reinforcing core materials 32, 32 and sprinkler materials 3 are provided on the front and back surfaces of the single core plate 31.
3 and 33 are laminated in order, and further on the surface side
The decorative veneer 34 as the surface decorative material, and the back side
A laminated portion described later in which a back single plate 35 as a back material is laminated
It has a structure formed by a reinforced plywood made of material 30.
Things.

The core single plate 31 forming the laminated member 30 is a plurality of 0.5 mm-thick single plates (in the illustrated embodiment, made of dense wood such as beech, hippo, moabi, macoret). (5 sheets) are laminated.

[0016] The reinforcing core member 32 forming the laminated member 30, are I sheet metal or Rana such as aluminum or an aluminum alloy having a thickness of 1.0mm was subjected to conversion coating treatment.

Further, the core material 33 forming the laminated member 30 is composed of a phenol resin-impregnated paper laminated cured plate (phenol backer) having a thickness of 0.6 mm.

Furthermore, the decorative veneer 34 as the surface decorative material forming the laminated member 30 is a veneer, mahogany, elm, zebra or the like having a thickness of 0.2 mm. .

The back single plate 35 as a back material forming the laminated member 30 is, for example, beech, hippo, moabi, ma
And veneer or lines cover thickness 0.2mm consisting dense wood such as Collector.

Then, in order to mold the spoke portion 3 made of such a reinforced plywood , as shown in FIGS. 5 and 6,
Each of the above-described constituent members, for example, a core single plate 31 having a plurality of 0.5 mm-thick single plates made of Moabi laminated (five in the illustrated embodiment), and a reinforcing core material 32 subjected to a chemical conversion coating treatment. A 1.0 mm thick aluminum plate, a 0.6 mm thick phenol resin impregnated paper laminated hardening plate as a sponge material 33, a 0.2 mm thick claro walnut as a decorative veneer 34, and a Moabi as a back veneer 35. By using a single plate having a thickness of 0.2 mm, a phenol resin film adhesive (not shown) is sandwiched between the layers of these laminated members 30, and the resultant is placed between the molds 5 and 6 and pressed and bonded. Done.

The adhesion conditions at this time are as follows: the pressure temperature is 140 ° C., the pressure is 2.5 MPa, and the pressure time is 12 minutes.

The reinforced plywood consisting of the laminated member 30 as the spoke half-molded product which is adhesively molded in this manner is finished into a desired shape by router processing, and the surface is coated with a polyester resin coating to give a mirror surface. To finish
After the surface treatment, the bolts 4 are attached to the rim portion 1 as shown in FIG.

By the way, the rim portion 1 is made of conventional wood,
A resin product or a resin product wrapped in leather is preferably used.

In the above embodiment, the laminated portion
The reinforcing core material 3 is provided on both front and back surfaces of the single core plate 31 forming the material 30.
2, 32 and sprinkling cores 33, 33 were respectively laminated in this order, but as shown as another embodiment in FIG. 7, one reinforcing core 32 is interposed between the core single plates 31, or in Figure 8
As shown as another embodiment , even if one reinforcing core material 32 is interposed in the middle of the single core plate 31 and the interposition of the sprinkling core materials 33, 33 is omitted, the operation and effect of the present invention The effect can be achieved sufficiently.

Further, although thin metal such as aluminum or aluminum alloy is used as the reinforcing core material 32, for example, it is made of fiber reinforced plastic having cloth such as carbon fiber, glass fiber, aramid fiber or boron fiber as reinforcing fiber. It is also possible to use a plate material.

[0026]

As apparent from the foregoing description, according to the steering wheel of an automobile or the like of the present invention, the spoke portion which <br/> connecting the rim portion and the hub portion, at least the core veneer and the reinforcing core material When
Since it is formed of a reinforced plywood composed of laminated members, the productivity can be improved by the plywood structure of the spoke portion, and a reinforcing core material made of a thin metal such as aluminum or aluminum alloy or a fiber reinforced plastic plate material. Even if it is thin, a sufficient strength can be obtained by stacking the layers, and thus, the durability can be improved.

Further , various decorative wood veneers can be used as a decorative veneer on the surface.
By using a plate, smart design that by the thinning
A rich variety of appearances with the design.
