Abstract

Profile clamp has a base and flanks facing radially inwards. The clamp utilizes a tensioning device that connects two ends of the clamp band to one another. The clamp band has in a circumferential direction at least a first part and a second part. The first part has in at least one of its flanks a first connection geometry and the second part in at least one of its flanks has a second connection geometry. The first connection geometry and the second connection geometry are engagable with one another.

First claim

What is claimed:

1. A profile clamp comprising:
a first part having a base and flanks;
a second part having a base and flanks;
a tensioning device configured to connect ends of the first and second parts to one another;
a first connection geometry arranged on the first part;
a second connection geometry arranged on the second part; and
the first connection geometry and the second connection geometry being engagable with one another so as to connect opposite ends of the first and second parts to one another,
wherein the first connection geometry is formed exclusively within each flank of the first part and the second connection geometry is formed exclusively within each flank of the second part, whereby the bases of the first and second parts are continuous and free of connection geometries, and
wherein the first connection geometry has a recess that opens radially outwardly relative to a circumferential direction of the profile clamp so as to engage with a portion of the second connection geometry.

2. The profile clamp of claim 1 , wherein the first connection geometry has a configuration that is complementary to the second connection geometry.

3. The profile clamp of claim 1 , wherein the base of the first part and the base of the second part have ends that one of:
bear against one another when the clamp is in a mounted state;
are spaced from each other via a gap; and
are spaced apart by a gap that is no more than a radial thickness of the base.

4. The profile clamp of claim 1 , wherein the first connection geometry further comprises a projection facing radially outwardly and being coupled to, in the circumferential direction, the recess.

5. The profile clamp of claim 1 , wherein the second connection geometry has a recess that opens radially inwardly relative to the circumferential direction of the profile clamp so as to engage with a portion of the first connection geometry.

6. The profile clamp of claim 5 , wherein the second connection geometry further comprises a projection facing radially inwardly relative to the circumferential direction of the profile clamp and being coupled to, in the circumferential direction, the recess of the first connection geometry.

7. The profile clamp of claim 1 , wherein the tensioning device is structured and arranged to allow radial movement of the first and second parts by an amount that is sufficient to allow for engagement between the first and second connection geometries.

8. The profile clamp of claim 1 , wherein the ends of first and second parts each comprise a bracket, and wherein the tensioning device further comprises:
a tensioning element that can extend through the brackets; and
a compression spring is arranged between the brackets.

9. The profile clamp of claim 8 , wherein the compression spring is sized and configured to align the brackets with one another.

10. A method of connecting together two pipe ends comprising:
arranging the profile clamp of claim 1 over ends of the pipes;
engaging with one another the first and second connection geometries; and
tightening the profile clamp.

11. A profile clamp comprising:
a first C-shaped clamping part having a base and flanks extending radially inward from the base;
a second C-shaped clamping part having a base and flanks extending radially inward from the base;
a tensioning element configured to connect ends of the first and second C-shaped clamping parts to one another;
a first connection geometry arranged on the first C-shaped clamping part and being located on an opposite end of the first C-shaped clamping part;
a second connection geometry arranged on the second C-shaped clamping part and being located on an opposite end of the second C-shaped clamping part; and
the first connection geometry and the second connection geometry being releasably engagable with one another,
wherein the first connection geometry is formed exclusively within each flank of the first C-shaped clamping part and the second connection geometry is formed exclusively within each flank of the second C-shaped clamping part,
wherein the first and second connection geometries are located radially inward with respect to each base,
wherein an imaginary plane passing through a center of each said base in a base thickness direction does not intersect the first and second connection geometries, and
wherein the first connection geometry has a recess that opens radially outwardly relative to a circumferential direction of the profile clamp so as to engage with a portion of the second connection geometry.

12. The profile clamp of claim 11 , wherein the first connection geometry has a configuration that is complementary to the second connection geometry.

13. The profile clamp of claim 11 , wherein the base of the first C-shaped clamping part and the base of the second C-shaped clamping part have ends that one of:
bear against one another when the clamp is in a mounted state;
are spaced from each other via a gap; and
are spaced apart by a gap that is no more than a radial thickness of the base.

14. A method of connecting together two pipe ends comprising:
arranging the profile clamp of claim 11 over ends of the pipes;
engaging with one another the first and second connection geometries; and
tightening the profile clamp via the tensioning element.

15. A profile clamp for connecting together ends of pipes, comprising:
a first C-shaped part comprising:
a connecting end;
a base; and
two spaced-apart radially inwardly oriented diverging flanks integrally formed with the base and extending to an opposite connecting end;

a second C-shaped part comprising:
a connecting end;
a base; and
two spaced-apart radially inwardly oriented diverging flanks integrally formed with the base and extending to an opposite connecting end;

a tensioning device configured to connect the connecting ends of the first and second parts to one another;
a first connection geometry located radially inward of the base and arranged on each of the two diverging flanks of the opposite connecting end of the first part;
a second connection geometry located radially inward of the base and arranged on each of the two diverging flanks of the opposite connecting end of the second part;
the first connection geometry and the second connection geometry being engagable with one another,
wherein the profile clamp is installable on the ends of the pipes so that the two diverging flanks contact tapered contact surfaces of the pipe ends,
wherein an imaginary plane passing through a center of each said base in a base thickness direction does not intersect the first and second connection geometries, and
wherein the first connection geometry has a recess that opens radially outwardly relative to a circumferential direction of the profile clamp so as to engage with a projection of the second connection geometry that extend radially inwardly relative to the circumferential direction.

16. The profile clamp of claim 15 , wherein:
the first connection geometry comprises the recess and a projection; and
the second connection geometry comprises a recess and the projection.
