ABSTRACT:
BACKGROUND OF THE INVENTION
Specifically, though not exclusively, the invention is applicable to the field of rapid attachment apparatus for machines for moving materials, such as, for example, buckets fitted onto the extremities of tool arms on work machinery. Numerous rapid attachment devices are taught in the prior art, which are suitable for the purpose but which are unable to solve definitively and satisfactorily the problem of automatic increase in play in the couplings between the parts, due to the not inconsiderable wear involved. The main aim of the present invention is to obviate the above-described limits in the prior art.
SUMMARY OF THE INVENTION
The invention has the advantages of being simply constructed and functional. A further advantage of the invention is the ease with which the coupling and uncoupling manoeuvres between the arm and the tool are carried out. A further advantage is the stability and safety of the coupling achieved. These aims and advantages and others besides are all achieved by the present invention, as it is characterised in the appended claims.
