HOUSEHOLD AND GARDENING DEVICE

WIPO Patent Application WO2003018271

A3

The invention relates to a household and gardening device comprising the element of a shaft coupling system, said element enabling the device, for example a rake, a grubber or the like, to be fixed to a shaft. Said element of the shaft coupling system, fixed to the device, comprises a tenon (10) which can be inserted into the shaft end and can be fixed therein by means of shaft-side coupling elements. An impact socket (12) can be slid over the tenon, said socket consisting of a head part (22) and a sleeve (20) which are embodied in a sheath-type manner and can be engaged and locked together. The sleeve is thus positioned in the head part (22) with plates (21) comprising holes which extend perpendicularly to the shaft axis and are aligned with holes (40) in the head part. The tenon comprises another hole (44) which can be thus be covered, and the socket is fixed without play by means of an interlocking pin (36) which penetrates all of the holes and fixes the socket to the tenon without play. Said interlocking pin forms part of a stop plug (32) which can be inserted into the head part in a flush manner. The shaft-side front surface of the sleeve is provided with a collar which surrounds the shaft end in the coupled state. Said front surface is provided with a plurality of symmetrical knops for compensating axial tolerances.
