Abstract
The invention discloses a steering device comprising a support structure having a central hole and at least two handgrips, at least one of these being mobile, placed in distal positions compared to the central hole and tied to the support structure by means of pivots. The mobile handgrip is rotatable around an axis substantially orthogonal to the plane of the support structure, so as to manually apply thereto a rotating motion around the axis of the column.
Claims17
A steering device comprising:
- a support structure comprising a central hole for fixing said support structure onto a steering column, wherein said support structure is rotatable together with the steering column to operate steering mechanisms;
- wherein the support structure comprises two spokes extending in a lying and rotating plane of the support structure;
- two rotatable handgrips respectively connected to the two spokes comprising said support structure, wherein the two handgrips are placed at distal positions with respect to the central hole, each of the two rotatable handgrips comprising:
- a pivot, rotatably attached to the support structure and freely rotatable, in a range from 0° to 360° without regard to rotation of the steering column, around a pivot attachment axis substantially orthogonal to the lying and rotating plane of said support structure,
- a first handgrip end segment, a second handgrip end segment which is a free end, and a third handgrip segment, the first handgrip end segment and the second handgrip end segment lying in respective end segment planes which are spaced apart and parallel to the lying and rotating plane of said support structure, the third handgrip segment being connected between the first handgrip end segment and the second handgrip end segment, the third handgrip end segment extending in a direction parallel to the pivot attachment axis, the second handgrip end segment having an essentially cantilever cylindrical shape and being configured to be gripped by a hand of a driver and to thereby manually impart a rotation motion around an axis of the steering column to the support structure,
- wherein an elongated slot is formed in each of the two spokes;
- wherein the pivot is adjustably positionable within the slot of the respective spoke in a direction of slot elongation which is orthogonal to the pivot attachment axis whereby an angle between the pivot axis and a center of the center hole is adjustable;
- wherein a free space is provided between a free end of the second handgrip end segment and said lying and rotating plane of said support structure.
