Abstract:
A pole provided with a quick-releasing interchangeable lateral support extension, which comprises a pole rod (1), a lateral support extension (5) fastened to the lower end of the pole rod, the said lateral support extension comprising a sleeve-like part (6, 8, 9) and a bearing surface extension (7), and quick-release means for fastening the pole rod (1) releasably inside the sleeve-like part of the lateral support extension (5), the quick-release means comprisinga sleeve socket (2), which is fixed onto the pole rod (1) by die casting or injection moulding, and which sleeve socket (2) has an upper end through which the pole tube (1) emerges, and a lower end; a resilient locking tongue (12) in the sleeve-like part (6, 8) of the lateral support extension; a locking projection (4) protruding from the sleeve socket, behind which projection the locking tongue (12) attaches by means of a snap joint characterised in that the lower end of the sleeve socket is fitted to remain inside the sleeve-like part (6, 8, 9) of the lateral support extension part (5); the sleeve socket (2) comprises a guide projection (3) protruding to the side near the upper end of the sleeve socket so that the said locking projection (4) remains below the guide projection (3); there is a guide groove (11) at the upper end of the sleeve-like part (6, 8, 9) of the lateral support extension, the said groove being dimensioned to receive the guide projection (3); and that there is a locking aperture (14) bordered by the locking tongue (12) in the sleeve-like part of the lateral support extension, the said aperture receiving the locking projection (4); which means that the locking projection (4) can be pushed into the locking aperture (14) past the resilient locking tongue (12), while the tongue (12) bends and snaps into the locking position behind the locking projection (4) at the same time as the guide projection (3) remains in the guide groove (11).
