Description

[Detailed Description of the Invention] The present invention relates to a steering handle structure for vehicles such as automobiles, aircraft, and ships.

Conventionally, a steering handle structure for a vehicle has been comprised of a hub fixed to a steering shaft, spokes projecting from the hub, and a rim fixed to the free ends of the spokes.

Driving a vehicle makes the driver nervous, causing sweating, and there is a risk of slipping between the rim and the hand when the rim rotates.

For this reason, some steering handles have recently been made with leather wrapped around the rim handle, and the rim cover covering the rim has been made uneven to prevent slippage.

However, with a handle whose rim handle is wrapped in leather, moisture causes the skin to become soft, making the handle less reliable.

Moreover, the leather wrapping operation requires a large number of man-hours and is not commensurate with the effectiveness.

Furthermore, even if the rim cover is made uneven, moisture on the rim cover and hands does not disappear, and an improvement has been desired.

For this reason, Japanese Patent Application Laid-open No. 51-1 (1983) proposed a device that blows air out of the rim of the handle to dry the hands themselves.
There are handle structures shown in Japanese Utility Model Publication No. 31029 and Japanese Utility Model Publication No. 457128.

However, if you grip the rim, the air outlet will definitely be blocked, and the air will not come out from the outlet, and the sweat from your palms will not be removed, making it impossible to achieve your goal. The disadvantage is that it does not.

In view of such conventional examples, the present invention aims to ensure that the rim and the palm of the hand do not slip, thereby providing a more comfortable driving condition.

In order to achieve this purpose, a steering wheel is constructed of a hub rotatably attached to a steering shaft, spokes fixed to the hub, and a rim fixed to the free ends of the spokes and having a cover. In the steering handle, the conditioned air dust provided along the steering shaft, the spokes and the rim are made hollow, and the conditioned air outlet provided in the rim is connected to the duct and the air outlet. a first coupling member, the coupling member being formed in the shape of a ring coaxial with the steering shaft and fixed to a steering column surrounding the steering shaft;
a second connector formed opposite to the first connector and fixed to the large steering handle or steering shaft at a distance from the first connector; and sealing a gap between the first and second connectors. and a duct-shaped sealing material together with the first and second connectors, and the regulated air outlet surrounds the core material of the rim and has a plurality of alternately concave portions and convex portions outward. A steering wheel for a vehicle comprising: an inlet provided in a concave portion of a formed rim cover; and an opening formed in a hollow portion of the rim core material, facing and communicating with a funnel-shaped portion of the inlet. It has a handle structure.

Next, the structure of one embodiment of the present invention will be explained using the drawings.

In the figure, 1 is a steering shaft, and 2 is a steering column surrounding the steering shaft 1.

3 is a steering handle provided on the steering shaft 1.

The steering handle 3 includes a hub 5 fixed to the steering shaft 1 with a nut 4, spokes 6 held by hub arms 5a projecting from the hub 5, and fixed to free ends 7 of the spokes 6. It is composed of a rim 8 and an air blowing device 9.

10 is a horn pad that covers a horn mechanism (not shown);
1 is a handle cover that covers the hub 5 and spokes 6.

The air blowing device 9 guides the conditioned air A that is forcibly discharged from an air conditioning mechanism (not shown) that adjusts temperature, humidity, aroma, blowing amount, etc., and also connects the duct 12 installed along the steering shaft 1. , a connector 13 that is fixed to the steering column 2 and the steering handle 3, respectively, and constantly communicates with the duct 12 even when the steering handle 3 is rotated; and a connector 13 that is inserted into a through hole 14 provided in the hub 5. and a hollow tube 15 communicating with the connector 13, the spoke 6 being hollow and the hollow portion 6a communicating with the tube 15,
Further, the rim 8 is made hollow so that it communicates with the hollow portions 6a of the spokes 6, and the outlet 16 for the conditioned air A is opened outwardly.

At the connection portion 17 between the rim 8 and the spokes 6,
When the rim 8 is expanded toward the spokes 6, the adjusted air A guided through the spokes 6 is diffused by the rim 8 and is discharged from the discharge ports 16 almost evenly.

The connector 13 is formed in a ring shape along the steering shaft 1, has a substantially U-shaped cross section, and has a first connector 8a fixed to the steering column 2.
A coupling member 18 is formed in a ring shape along the steering shaft 1 so as to face the opening of the first coupling member 18, and has a cross section approximately in the shape of an inverted U.
a second connector 19 that is spaced apart from the connector 18 and fixed to the steering handle 3 or the steering shaft 1;
and the gap 20 between the first connector 18 and the second connector 19 is sealed, and the first and second connectors 18, 19 are connected to each other.
The duct 12 is configured to communicate with the first connector 18, and the lube 15 communicates with the second connector 19.

The sealing material 21 is attached to either the first connector 18 or the second connector 19.

The rim 8 includes a rim core material 22 having a substantially circular hollow 22a fixed to the free ends 7 of the spokes 6, and a rim core material 22 surrounding the rim core material 22. or FIG. 2 (as in the two embodiments shown, the rim covers 25 are provided alternately).

The discharge port 16 is connected to an air inlet 27 provided in the concave portion 23 of the rim cover 25 and a hollow portion 2 of the rim core material 22.
2a, and an opening 26 that faces and communicates with the funnel-shaped portion G of the inlet 27, as shown in FIG.

It is desirable that the rim cover 25 be provided at a position on both the left and right sides of the steering handle 3 so that it can be grasped by an occupant.

In the figure, 28 is a horn switch, and 29 is the horn pad 1.
a screw 30 for fixing 0 to the hub arm 5a of the hub 5;
31 is a pedestal integrated with the hub arm 5a, and 31 is a spoke 6.
A sealer material 32 provided on the rim core material 22 is a covering member that covers the rim core material 22 and the end of the rim cover 25.

Further, the spoke 6 has a discharge port for blowing air out from the discharge port 16.
It may also be provided together with

Since the present invention has such a configuration, its operation will be explained next.

Even when the steering handle 3 is rotated, the duct 12 and the spokes 6 are always in communication via the connector 13.
The conditioned air A can be discharged to the outside from the discharge port 16 at all times.

Moreover, since the first and second connectors 18 and 19 are separated from each other, even when the handle 3 is turned, the duct 12 is not biased and twisted.

Therefore, according to the present invention, the conditioned air A can make the palms of the occupant who is gripping the rim 8 comfortable and suppress the generated sweat, and when the air is discharged from the spokes, the occupant and the outlet Since the air temperature is close to the air temperature, the air is discharged to the occupants without changing the air temperature, which provides comfort.
