Abstract
An apparatus to connect an implement to a first apparatus, the apparatus including a first part adapted for attachment to the first apparatus, a second part adapted for attachment to a second apparatus. The first and second parts are articulated one with the other about an articulation axis. The parts are actuable between modes whereby, in one mode, the first and second parts can articulate relative to each other, and, in the second mode, the first and second parts cannot articulate relative to each other.
Claims22
An apparatus to connect an implement to a first apparatus, said apparatus comprising
- a first part adapted for attachment to said first apparatus,
- a second part adapted for attachment to a second apparatus,
- said first and second parts being articulated one with respect to the other about an articulation axis, and
- articulation enabling means actuable between modes whereby, in a first mode, the first and second parts can articulate relative to each other under any applied force as a result of a reduced frictional resistance to articulation between the first and the second parts about an articulation axis, and, upon positive actuation of a second mode, the first and second parts cannot articulate relative to each other under the any applied force as a result of an increased frictional resistance to articulation between the first and second parts about the articulation axis.
Coupling apparatus to connect an implement to a boom assembly of a machine, said coupling apparatus comprising:
- a first part adapted to be pivotally attached to the boom assembly at each of two spaced axes of the first part so as to be angularly controllable in a plane normal to a boom axis by a differential movement of the boom;
- and
- a second part articulated from said first part on an articulation axis in or parallel to said plane, said second part being adapted for attachment to an implement by capture of part of the implement thereof so that the implement will be positionally controlled by the disposition of said second part,
- wherein articulation at the articulation axis is controllable by articulation enabling means providing, upon positive actuation, a high friction between proximate surfaces of the first part and the second part locking such articulation and the articulation enabling means providing a reduced friction between proximate surfaces of the first part and the second part allowing such articulation.
