Abstract

Profiled clamp that includes a clamping element, a sealing element having elastically deformable spacers on a radial outside, and a profile band on which the sealing element is held secured against loss. The elastically deformable spacers bear against an inside of the profile band in a non-positive manner.

Claims (31)

1. A profiled clamp comprising:

a clamping element;

a sealing element having elastically deformable spacers spaced around a circumference on a radial outside of the sealing element; and

a profile band on which the sealing element is held secured against loss,

wherein the elastically deformable spacers bear against an inside of the profile band in a pre-loaded manner,

wherein each spacer comprises, in a circumferential direction of the sealing device: a fixed end connected to the sealing element, followed by a contact region structured and arranged to bear against the inside of the profile band, followed by a free end, and

wherein the contact region is arranged furthest radially outwards in a non-tensioned state of the profile clamp.

2. The profiled clamp according to claim 1 , wherein the sealing element comprises a metal seal.

3. The profiled clamp according to claim 1 , wherein the spacers are formed in one piece with the sealing element.

4. The profiled clamp according to claim 1 , wherein the spacers are extendible in a circumferential direction of the sealing element.

5. The profiled clamp according to claim 1 , wherein the free end is rolled radially inwardly.

6. The profiled clamp according to claim 1 , the profile band comprises radial projections formed on the inside.

7. The profiled clamp according to claim 1 , wherein the profile band has two clamping heads with which the clamping element interacts.

8. The profiled clamp according to claim 1 , wherein the profile band comprises two profile walls.

9. The profiled clamp according to claim 8 , wherein at least one joint is formed in each of the profile walls.

10. The profiled clamp according to claim 8 , wherein the profile walls are arranged to form one of a U- or V-shaped channel.

11. The profiled clamp according to claim 8 , wherein the profiled walls are arranged so that, as the clamping element is tightened, pipe ends to be connected are pressed against opposite sides of the sealing element.

12. The profiled clamp according to claim 1 , wherein a cross-section of the sealing element comprises steps.

13. A profiled clamp comprising:

a clamping element;

a profile band having a radially inwardly opening channel;

a sealing element having a plurality of spacers formed on an outer radial surface and spaced around a circumference, the plurality of spacers being elastically deformable to bear against an inside of the channel; and

at least one radial projection formed in the channel that is structured and arranged for positioning the sealing element,

wherein each spacer comprises, in a circumferential direction of the sealing element, a fixed end connected to the sealing element, followed by a contact region structured and arranged to bear against the inside of the profile band, followed by a free end, and

wherein the contact region is arranged furthest radially outwards in a non-tensioned state of the profiled clamp.

14. The profiled clamp according to claim 13 , wherein the sealing element comprises a metallic seal.

15. The profiled clamp according to claim 13 , wherein the spacers are formed to extend in a circumferential direction.

16. The profiled clamp according to claim 13 , wherein the free end is rolled-up around an axis parallel to a tangent to the outer radial surface.

17. The profiled clamp according to claim 13 , wherein a cross-section of the sealing element comprises steps radially inside of the plurality of spacers.

18. The profiled clamp according to claim 6 , wherein the spacers are structured and arranged to interact with the radial projections to secure the sealing element against loss from the profile band when the clamp is in a non-tensioned state.

19. The profiled clamp according to claim 13 , wherein the spacers are structured and arranged to interact with the at least one radial projection to secure the sealing element against loss from the profile band when the clamp is in a non-tensioned state.
