The spherical joint consists of two hemispheric shells (2 fig.1) and two ferrules of the coupling quick (1 fig.1), respectively screwed to the two shells through two fixing flared screws M6 (3 fig.1). Each of these ferrules with his half shell, they are anchored, will be the semi joint, can rotate 25 ° with the half shell. It has established a ZERO position for the ring-nut in line with the inclusion of linear bumps of it (7 fig. 4) on the grooves cut on the shell (5 fig. 3). The two semi joints can be assembled to form the joint using four conical connections, the next rotation of the two ferrules in the opposite direction, respectively 3.2-degree angle to the position of ZERO (ON) allows the coupling of the two semi joints and in this situation it is in A position (OFF) and the linear protuberance in the sear of lower ring-nut (5 fig.4) is inserted into the corresponding slot (6 fig.4) extracted by the sear of the ring on top and vice versa. The release of the two semi joints is obtained by making again rotations of ferrules in the opposite direction and returning to the configuration of ZERO. This invention essentially allows for a coupling between the two semi-joints making a simple insertion and rotation similar to those that we do in the screw coupling_ nut, while avoiding the difficulties and costs to realize that. |
