Device for vehicles for carrying out a steering movement
Device for vehicles, in particular fork-lift trucks, the device being designed at least for carrying out a steering movement of the vehicle, the device being arranged on an arm rest of a vehicle seat of the vehicle, wherein the device is at least partially rotatable about a first pivot axis relative to the arm rest, wherein rotation of the device about the first pivot axis causes the steering movement of the vehicle, and wherein the device comprises a first device element arranged above the arm rest, and a second device element which is fixedly connected to the first device element and extends downwards from the first device element beyond the first device element.
1 . A device for vehicles, in particular fork-lift trucks, the device being designed at least for carrying out a steering movement of a vehicle, the device being arranged on an arm rest of a vehicle seat of the vehicle, wherein the device is at least partially rotatable about a first pivot axis relative to the arm rest, wherein rotation of the device about the first pivot axis causes the steering movement of the vehicle, wherein the device comprises:
a first device element arranged above the arm rest, and
a second device element which is fixedly connected to the first device element and extends downwards from the first device element beyond the first device element, and wherein the device comprises at least one rotatable wheel element which can be at least partially embraced on a circumferential side by fingers of a hand of a vehicle driver placed on the device and can be rotated about an axle for the steering movement, the second device element being fixedly connected to the wheel element and extending downwards from the wheel element beyond the wheel element.
2 . The device according to claim 1 , wherein the first device element and the second device element are provided and designed such that the hand can be at least partially placed thereon, wherein during a forward movement of the vehicle the hand can be at least partially placed on the first device element and during a rearward movement of the vehicle the hand can be at least partially placed on the second device element.
3 . The device according to claim 1 , wherein the first pivot axis is arranged extending in a height direction of the device or at an acute angle to the height direction.
4 . The device according to claim 1 , wherein a steering ratio from a rotation angle of the device to a steering angle is progressive.
5 . The device according to claim 1 , wherein a resetting unit is provided which resets the device to a neutral position.
6 . The device according to claim 5 , wherein a haptic signal is emitted when the device is in the neutral position.
7 . The device according to claim 1 , wherein a rotary movement of the device can be subjected to a proportional counterforce, such that a greater rotary movement experiences a greater counterforce.
8 . The device according to claim 1 , wherein first function keys and indicators are arranged on the first device element and second function keys and indicators are arranged on the second device element.
9 . A device for vehicles, the device being designed at least for carrying out a steering movement of a vehicle, the device being arranged on an arm rest of a vehicle seat of the vehicle, wherein the device has:
a first device element arranged above the arm rest, and
a second device element fixedly connected to the first device element and extending downwardly from the first device element beyond the first device element,
wherein the device is arranged substantially rigidly relative to the arm rest and the steering movement of the vehicle is caused by means of a force action and/or a torque action on the device, and wherein the device comprises at least one rotatable wheel element that is at least partially embraceable on a circumferential side by fingers of a hand of a vehicle driver placed on the device and rotatable about an axle for a steering movement, the second device element being fixedly connected to the wheel element and extending downwards from the wheel element beyond the wheel element.
10 . The device according to claim 9 , wherein each value of an application of force and/or torque is associated with a steering angle of the vehicle.
11 . The device according to claim 9 , wherein a sensor is provided by means of which the force action and/or torque action can be measured.
12 . The device according to claim 9 , wherein an elastic element is disposed between the device and the arm rest.
13 . A device for vehicles, in particular fork-lift trucks, the device being designed at least for carrying out a steering movement of a vehicle, the device being arranged on an arm rest of a vehicle seat of the vehicle, wherein the device is rotatable about a first pivot axis relative to the arm rest, wherein rotation of the device at a pivot angle about the first pivot axis causes steering movement through a steering angle, a steering ratio being progressive from pivot angle to steering angle, wherein the device comprises:
a first device element arranged above the arm rest,
a second device element fixedly connected to the first device element, and
at least one rotatable wheel element that is at least partially embraceable on a circumferential side by fingers of a hand of a vehicle driver placed on the device and that can be rotated about an axle for the steering movement, wherein the second device element is fixedly connected to the wheel element and extends downwards from the wheel element beyond the wheel element.
14 . The device according to claim 13 , wherein the second device element extends downwards from the first device element beyond the first device element.
15 . The device according to claim 13 , further comprising a resetting unit that resets the device to a neutral position.
16 . The device according to claim 15 , wherein the device emits a haptic signal when in the neutral position.
17 . The device according to claim 13 , wherein the first device element comprises first function keys and indicators, and wherein the second device element comprises second function keys and indicators.
18 . The device according to claim 13 , further comprising a sensor configured to measure at least one of a force action and a torque action on the device.
19 . The device according to claim 13 , wherein the first pivot axis extends in a height direction of the device or at an acute angle to the height direction.
20 . The device according to claim 13 , wherein an elastic element is disposed between the device and the arm rest.
