The steering wheel comprises a column section, a steering shaft passing through the column section, a boss portion secured to the top of the steering shaft, a boss plate secured on the boss portion, a pad section, a plurality of sun gears of the helical gear type, a plurality of planetary shafts, a plurality of pairs of planetary gears of the helical gear type attached to either end portion each of the respective planetary shafts and gearing with the corresponding sun gears, and a resilient member for urging the planetary gears of a pair mounted on at least one of the plural planetary shafts. At least one of the paired planetary gears is attached movably in the longitudinal direction of the axis of that planetary shaft, so that these planetary gears approach mutually or separate from each other in the axial direction of the respective planetary shaft.

Steering wheel

Herein disclosed is a steering wheel structure which has a stationary pad. On a steering shaft, there are mounted a boss plate of the steering wheel and column-side and pad-side sun gears. The boss plate is formed with at least one mounting recess which is opened to the outside. In this mounting recess, there is rotatably mounted through an intermediate member at least one planetary shaft which has column-side and pad-side planetary gears at its two ends. Upon assembly, the two planetary gears are brought into respectively meshing engagements with the two sun gears from the radially outer sides of the same.

A microprocessor-based telephone set includes a telephone number memory, a number indicator, an abbreviated number scanning switch and associated control circuit, in addition to a push-button dial and a hook switch as equipped in the usual telephone set. Telephone numbers are preset in correspondence to abbreviated numbers, so that a telephone number is dialed automatically by simply specifying a corresponding abbreviated number using the scanning switch and indicator. By provision of an FM transceiver within the handset and a separate relay unit for establishing radio communication with the base telephone station, a mobile telephone system is configured.

Telephone equipment for reduced key operations

A steering wheel having a telephone includes a pad portion secured to a steering shaft, wherein the pad portion comprises a base held on the steering shaft and a telephone detachably held on the base, the base has a receiving recess and a swing projection with which the telephone is engaged, and the telephone has an engaging recess in engagement with the swing projection and a radio communication means for transferring signals. Therefore, the driver can use the telephone of the present invention in his driving attitude without picking up it during operation of the steering wheel and other occupants can also pick up it from the steering wheel.

A steering wheel comprises a rotatable steering shaft, a boss fixed onto the steering shaft, a pad non-rotatable mechanism mounted on the boss and used to hold pad means stationary, a support member for attaching the column-side non-rotatable member of the pad non-rotatable mechanism to the boss in such a manner that the column-side non-rotatable member is rotatable relative to the boss and stopper means provided on the column-side non-rotatable member and used to make the column-side non-rotatable member non-rotatable relative to a column.

A steering wheel includes a steering shaft, column and pad sun gears mounted on the steering shaft for rotation relative thereto, a boss plate mounted on the steering shaft between the sun gears and rotatable in unison with the steering shaft, at least one bearing mounted on the boss plate and movable toward and away from a center of the boss plate, a planet shaft rotatably supported by the bearing, and column and pad planet gears mounted on opposite ends of the planet shaft and held in mesh with the column and pad sun gears, respectively, the planet gears having inner side surfaces rotatably held in contact with opposite outer side surfaces of the bearing.

A pad holder mechanism for use in a steering wheel includes circular guide members mounted respectively on a steering column and a pad disposed one on each side of a boss plate in an axial direction of a steering shaft, the guide members being immovable in the axial direction of the steering shaft. The guide members have continuous cam elements displaced in the axial direction throughout their circumferential length. The boss plate supports a pair of coacting members having opposite ends movable in phase along the cam elements on the guide members. The coacting members and the guide members are relatively positioned such that when the ends of one of the coacting members are positioned at peaks of the displaced cam elements, the ends of the other coacting member are located in positions other than peaks of the displaced cam elements.

A relay arrangement for transmitting electrical signals from various switches of an automobile to various devices controlled by the switches comprises a cable, and a boss plate rotatably held to the steering shaft of the automobile. The cable has a spiral winding between two sun gears, and the boss plate extends between two neighboring turns of the winding. The number of turns of the winding is in excess of the maximum number of revolutions that the steering wheel can make. When the boss plate is rotated during the rotation of the steering wheel, the plate slides through the winding in a plane perpendicular to the axis of the winding.

Relay arrangement for steering wheel

A steering wheel of the stationary pad type includes a steering shaft carrying thereon a boss plate, a first sun gear secured to a column and a second sun gear secured to a pad. At least one planetary shaft is rotatably supported on the boss plate, and has one end on which a first planetary gear meshing with the first sun gear is supported, while a second planetary gear meshing with the second sun gear is supported on the other end of the planetary shaft. The first and second planetary gears are normally held by a resilient device in intimate engagement with the first and second sun gears, respectively, but displaceable therefrom in the event foreign matter is caught between the planetary and sun gears.

A steering wheel includes a column, a steering shaft extending through the column, a spoke mounted on the steering shaft, a steering ring supported on the spoke, a pad mounted on the steering shaft in front of the spoke, and a helical member interconnecting the pad and the column to fix the pad nonrotatably with respect to the column and helically coiled as a number of turns which is greater than the maximum number of rotations of the steering ring, the helical member having a portion extending across the spoke.
