<p>An axis joint for journalling parallel connecting pieces (22, 23) to a construction element via a bearing bushing (26) and a bearing shaft (30) having outwardly diverging recesses (33, 34) to form conical surfaces (35, 36) and a clamping portion (37, 38), the joint also having conical washers (44, 45) for cooperation with the clamping portions. According to the invention, under influence of a screw (48, 49), the clamping portions (37, 38) abut directly against the connecting pieces so that a butt connection is obtained. The bearing shaft is in the form of a sleeve with an opening (43) having a diameter equivalent to the smallest diameter of the recesses. The bearing bushing contains a slide bearing sleeve (28) with internal, resilient, sealing lips (52, 53), and a space (61, 62) is arranged so that the sealing lips (52, 53) can expand freely upon insertion of the bearing shaft (30) into the sleeve (28) and resiliently abut against the bearing shaft (30). In inoperative state the sealing lips (52, 53) have an inner diameter less than the diameter of the bearing shaft (30).</p> |
