Abstract

An elevation mechanism for a central input selector knob includes: a cylindrical cam having two cylindrical rails; a central input device mounted on a slider cylinder having two opposite ends of a pin that run in the two cylindrical rails to move the central input device between an operation position and a storage position; a cap that has two opposite guiding ribs configured to slide into rails of a main housing, the cap being attached to the main housing such that the slider cylinder is enclosed by the main housing and the cap; and a motor having an axis where a second gear is mounted, the second gear being configured and arranged to transmit movement to a first gear thereby causing the slider cylinder to move thereby moving the central input device between the operation position and the storage position.

First claim

The invention claimed is:

1. An apparatus comprising:
a cylindrical cam having a circular cross section and having two cylindrical rails that are inclined along and formed into a curved sidewall of the cylindrical cam;
a central input device mounted on a slider cylinder having two opposite ends of a pin, wherein the pin rotates about a central axis of rotation along with the slider cylinder, within the cylindrical cam, such that the opposite ends of the pin run in the two inclined cylindrical rails in the curved sidewall of the cylindrical cam to convert the rotational movement of the slider cylinder and the pin within the cylindrical cam into linear movement to move the central input device between an elevated operation position and a lowered storage position;
a cap that has two opposite guiding ribs configured to slide into rails of a main housing, the cap being attached to the main housing such that the slider cylinder is enclosed by the main housing and the cap;
a motor having an axis where a second gear is mounted, the second gear being configured and arranged to transmit movement to a first gear thereby causing the pin and the slider cylinder to rotate thereby causing the opposite ends of the pin to run in the inclined cylindrical rails to convert the rotational movement into linear movement thereby moving the central input device between the operation position and the storage position;
wherein the slider cylinder is welded to a conical gear, which is mounted to a shaft in the main housing; and
wherein the conical gear is moved by a conical pinion and the first gear that are mounted to a first-gear-and-conical-pinion shaft, which has a bushing that is attached to the main housing.

2. The apparatus of claim 1 , wherein the slider cylinder has three guiding features.

3. The apparatus of claim 1 , wherein the central input device further comprises a multifunction switch.
