<p>Referring to the figure, a space joint with central inner rods tightening 1 (1.1 - 1.3) comprises a body 2a or 2b, a tightening body 3.1a or 3.1b respectively; or 3.2; or 3.3; or similar, a screw 4.1, a washer 4.4.1.1, an additional body 4.3.1, a washer 4.4.1.2, a washer 4.4.2.2, an additional body 4.3.2, a washer 4.4.2.1, a securing 4.2.1, and a nut 4.5. General geometry of the joint body (2) is described in P 950575 a, so that the joint body 2 (Pos. 2a, or Pos. 2b) is cut with two planes that are perpendicular to a space diagonal of the joint body 2 (Pos. 2a or Pos. 2b) that passes through two joint body top points that are equidistant from them, so that around the space diagonal exists the hole which passes diagonally through the whole joint body, so that the surface of the space diagonal hole partly intersects surfaces of the side holes. A tightening insert (3) is used for the rods 1 (1.1 - 1.3) tigthtening to joint body 2 (Pos. 2a or 2b) from inside, so that a tightening force of tightening bush (3) is obtained: a) in use of tightening body 3 (Pos. 3.1a and 3.1b respectively; or Pos. 3.2, or 3.3 or similar) by using a screw 4.1, a washer 4.4.1.1, an additional body 4.3.1, washer 4.4.1.2, a washer 4.4.2.2, an addtional body 4.3.2, a washer 4.4.2.1 , a securing 4.2.1 and a nut 4.5, so that on one side of the tightening system has to be secured free entering of all elements in the joint body hole, while from the other side a corresponding washer 4.4 (4.4.1; 4.4.1.2; 4.4.2.1 or 4.4.2.2) ensures supporting of the joint body; b) same as in a), so that the space diagonal hole is towards one of diagonal top point of smaller cross section, and in principle adopted to the screw 4.1 dimension; c) same as in b), so that in the diagonal hole of smaller cross section thread is performed in which the screw 4.1 is screwed, so that for tightening the screw 4.1, the securing 4.2.1, the washer 4.4.1.1, the additional body 4.3.2 and the washer 4.4.2.2 can be used.</p> |
