Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
166 words
A plastic screw joint including a hollow cylindrical intermediate connection piece having a box nut, said intermediate connection piece being provided with circularly arranged clamping tongues forming an annular clamping tongue arrangement, said clamping tongues urging the sealing body inwardly against a workpiece as the box nut is screwed on, wherein the clamping tongues are segmented and arranged adjacent to each other and when the clamping tongues are positioned closely adjacent each other, they are separated by slots, inclined obliquely relative to the respective diameter, and a predetermined number of such slots is followed by a slot inclined by the same angle but in opposite direction so that a wedge-like shape is obtained for every selective clamping tongue being disposed between two such oppositely directed slots due to which shape it is urged inwardly and out of the remaining annular clamping tongue arrangement when the box nut starts to exert pressure, whereby a non-circular relation between the cable and the annular clamping tongue arrangement is obtained.
Claim 2
Dependent Claim
166 words
A plastic screw joint including a hollow cylindrical intermediate connection piece having a box nut, said intermediate connection piece being provided with circularly arranged clamping tongues forming an annular clamping tongue arrangement, said clamping tongues urging the sealing body inwardly against a workpiece as the box nut is screwed on, wherein the clamping tongues are segmented and arranged adjacent to each other and when the clamping tongues are positioned closely adjacent each other, they are separated by slots, inclined obliquely relative to the respective diameter, and a predetermined number of such slots is followed by a slot inclined by the same angle but in opposite direction so that a wedge-like shape is obtained for every selective clamping tongue being disposed between two such oppositely directed slots due to which shape it is urged inwardly and out of the remaining annular clamping tongue arrangement when the box nut starts to exert pressure, whereby a non-circular relation between the cable and the annular clamping tongue arrangement is obtained.
Claim 3
Dependent Claim
83 words
A screw joint according to claim 1, characterized in that when the box nut has been screwed on, two active areas are formed at different axial heights between the mounted-cable and the selective clamping tongues that have been urged inwardly and the remaining annular clamping tongue arrangement, so that all of the pressure forces exerted by the clamping tongues for pull-relieving and protecting the workpiece against torsion are distributed over an axial surface area resulting in a reduction of the specific pressure force.
Claim 4
Dependent Claim
32 words
A screw joint according to claim 1, characterized in that the clamping tongues are formed integrally with the hollow-cylindrical intermediate connection piece and coaxially thereto, to form said annular clamping tongue arrangement.
Claim 5
Dependent Claim
36 words
A screw joint according to claim 1, characterized in that three selective clamping tongues formed by a corresponding segmentation are spaced uniformly about the circumference of the annular clamping tongue arrangement at angles of 120 degrees.
Claim 6
Dependent Claim
27 words
A screw joint according to claim 1, characterized in that all clamping tongues cut upon the workpiece via an interposed annular packing extending in the axial direction.
