Abstract

A clamping apparatus connecting tube flanges, includes first and second bracing devices. The first bracing device connects first and second mounting devices and has a partially circular shape with a first inner and a first outer wall. The second bracing device connects first and second connecting devices. The first bracing device inner wall has a first recess. The first bracing device outer wall is configured to contact the second bracing device which is configured to contact the first bracing device outer wall to apply substantially radial force on that first outer wall. The first recess shape is configured to substantially convert the radial force applied to the first bracing device outer wall into an axial force inside the first inner wall. The first and second mounting devices each comprise at least two attachment devices connecting the first and second connecting devices of the second bracing device.

First claim

The invention claimed is:

1. A clamping apparatus for connecting flanges of tubes, comprising:
a first bracing device;
a second bracing device;
wherein the first bracing device connects a first mounting device and a second mounting device;
wherein the first bracing device has a partially circular shape with a first inner wall and a first outer wall;
wherein the second bracing device connects a first connecting device and a second connecting device;
wherein the first inner wall of the first bracing device has a first recess which has a V-shape;
wherein the first outer wall of the first bracing device is configured to contact the second bracing device;
wherein the second bracing device is configured to contact the first outer wall of the first bracing device in order to apply a substantially radial force on the first outer wall of the first bracing device;
wherein the second bracing device is disposed over the first bracing device, such that the second bracing device is adapted to cover the first bracing device;
wherein the shape of the first recess is configured to substantially convert the substantially radial force applied to the first outer wall of the first bracing device into an axial force inside the first inner wall; and
wherein the first mounting device and the second mounting device each comprise at least two attachment devices for connecting the first connecting device and the second connecting device of the second bracing device.

2. The clamping apparatus of claim 1 , wherein the second bracing device is at least one of at least partially made of a substantially flexible material or configured as a flexible element.

3. The clamping apparatus of claim 1 , wherein the second bracing device is at least partially made of a substantially rigid material.

4. The clamping apparatus of claim 1 ,
wherein the second bracing device has a partially circular shape with a second inner wall and a second outer wall;
wherein the second inner wall of the second bracing device has a second recess; and
wherein a shape of the second recess is configured to engage with the first outer wall of the first bracing device.

5. The clamping apparatus of claim 4 , wherein the second recess has a V-shape.

6. The clamping apparatus of claim 1 ,
wherein the at least two attachment devices are configured to receive at least one fixing device selected from a group of fixing devices consisting of:
a bolt;
a pin;
a screw;
a clip; and
a rivet.

7. The clamping apparatus of claim 1 , wherein the first bracing device and the second bracing device are connected to another.

8. The clamping apparatus of claim 7 , wherein the first bracing device and the second bracing device are connected to one another by a hinge.

9. A clamping system, comprising:
at least two clamping apparatuses of claim 1 ,
wherein the at least two clamping apparatuses are connected by at least four fixing devices selected from a group of fixing devices consisting of:
a bolt;
a pin;
a screw;
a clip; and
a rivet.

10. A tube system, comprising:
a first tube with a first flange;
a second tube with a second flange;
wherein the first flange and the second flange are connected by the clamping system of claim 9 .

11. The tube system of claim 10 , wherein at least one of the first tube and the second tube is a hose.

12. The tube system of claim 11 , further comprising:
a jacket;
wherein the first tube and the second tube and at least one of the clamping apparatus or the clamping system are surrounded by the jacket.

13. The tube system of claim 12 , wherein the tube system is built as a hose-in-shroud system.

14. An airplane comprising at least one clamping apparatus of claim 1 .

15. An airplane comprising the clamping system of claim 9 .

16. A tube system, comprising:
a first tube with a first flange;
a second tube with a second flange;
wherein the first flange and the second flange are connected by a clamping apparatus, the clamping apparatus comprising:
a first bracing device;
a second bracing device;
wherein the first bracing device connects a first mounting device and a second mounting device;
wherein the first bracing device has a partially circular shape with a first inner wall and a first outer wall;
wherein the second bracing device connects a first connecting device and a second connecting device;
wherein the first inner wall of the first bracing device has a first recess;
wherein the first outer wall of the first bracing device is configured to contact the second bracing device;
wherein the second bracing device is configured to contact the first outer wall of the first bracing device in order to apply a substantially radial force on the first outer wall of the first bracing device;
wherein the shape of the first recess is configured to substantially convert the substantially radial force applied to the first outer wall of the first bracing device into an axial force inside the first inner wall; and
wherein the first mounting device and the second mounting device each comprise at least two attachment devices for connecting the first connecting device and the second connecting device of the second bracing device.

17. The tube system of claim 16 , wherein at least one of the first tube and the second tube is a hose.

18. The tube system of claim 17 , further comprising:
a jacket;
wherein the first tube and the second tube and at least one of the clamping apparatus or the clamping system are surrounded by the jacket.

19. The tube system of claim 18 , wherein the tube system is built as a hose-in-shroud system.

20. A clamping apparatus for connecting flanges of tubes, comprising:
a first bracing device;
a second bracing device;
wherein the first bracing device connects a first mounting device and a second mounting device;
wherein the first bracing device has a partially circular shape with a first inner wall and a first outer wall;

wherein the second bracing device connects a first connecting device and a second connecting device;
wherein the first inner wall of the first bracing device has a first recess;
wherein the first outer wall of the first bracing device is configured to contact the second bracing device;
wherein the second bracing device is configured to contact the first outer wall of the first bracing device in order to apply a substantially radial force on the first outer wall of the first bracing device;
