Abstract
An agricultural or industrial utility vehicle includes a vehicle body, an operator's platform and a pivot assembly, by means of which the operator's platform can be pivoted on the utility vehicle about an essentially horizontal pivot axis. The pivot assembly includes at least two guide arms of differing lengths and/or extending in non-parallel directions. Each guide arm has one end which is coupled at a joint to the operators platform and another end which is coupled at another joint to the vehicle body. The connecting joint axes of the guide arms are essentially parallel to each other and are spaced apart from each other. Such a pivoted operator's platforms permits access for maintenance, repair or cleaning of vehicle components which are arranged under the operator's platform.
Claims14
In a vehicle having a body, an operator's platform and a pivot assembly which pivotally couples the operator's platform to the vehicle about a generally horizontal pivot axis, the pivot assembly comprising:
- a pair of guide arms having differing lengths and which extend in non-parallel directions, each guide arm having one end coupled at a first joint to the operator's platform and having another end coupled at a second joint to the vehicle body, said joints having axes which extend generally parallel to each other and which are spaced apart from each other;
- and
- an implement hitch having a lift arm coupled to the vehicle body, the lift arm comprising a first guide arm of the pivot assembly, the lift arm being coupled to the operator's platform by a connecting joint.
A pivot assembly for pivotally coupling an operator's platform to a body of a utility vehicle, characterized by:
- a strut connected rigidly to the operators platform;
- a first guide arm rotatably coupled to the strut;
- a power motor coupled to the strut;
- and
- a second guide arm coupled to the strut and pivotally coupled to the body.
