Abstract

Flange for a hose (2), which flange comprises: —an annular flange body (4) having a central hose opening (5); —an annular locking element (9) for locking the annular flange body (4) in a circumferential groove (3) of a hose (2), which annular locking element (9) is composed out of at least two generally arc shaped locking element parts (9), wherein the annular locking element (9) is concentrically arranged in the central hose opening (5) of the annular flange body (4); and —couplings (7, 8) for each of the at least two generally arc shaped locking element parts (9), wherein each coupling (7, 8) has a first coupling part (7) arranged on the annular flange body (4) and a second coupling part (8) arranged on the respective arc shaped locking element part (9), which first coupling part (7) couples to the second coupling part (8).

First claim

The invention claimed is:

1. A flange for a hose comprising:
an annular flange body having a central hose opening;
an annular locking element for locking the annular flange body in a circumferential groove of a hose, which annular locking element is composed out of at least two generally arc-shaped locking element parts, wherein the annular locking element is concentrically arranged in the central hose opening of the annular flange body; and
couplings for each of the at least two generally arc-shaped locking element parts, wherein the couplings have a first coupling part arranged on the annular flange body and a second coupling part arranged on the respective arc-shaped locking element part, which first coupling part couples to the second coupling part, one of the first and second coupling parts including a protrusion protruding from a first surface, the first surface facing radially outward or radially inward, the other of the first and second coupling parts including a groove recessed from a second surface, the second surface facing the first surface, and the first surface and the second surface being configured to abut each other when the protrusion is received in the groove,
wherein a cross-section of the protrusion and a cross-section of the groove are T-shaped.

2. The flange according to claim 1 , wherein the first coupling part is the groove recessed from the second surface and extending in an axial direction from a first end surface of the annular flange body, wherein a length of the groove is smaller than a thickness of the annular flange body, and wherein the second coupling part is the protrusion protruding from the first surface of the respective arc-shaped locking element part, which protrusion has in axial direction a cross-section corresponding to a cross-section of the groove.

3. The flange according to claim 1 , wherein an inner diameter of the annular locking element corresponds with an outer diameter of the circumferential groove of the hose.

4. The flange according to claim 1 , wherein the annular flange body has a number of axially extending through holes evenly positioned along the circumference of the annular flange body.

5. The flange of claim 1 , wherein the groove is an axially extending groove, and wherein the protrusion is an axially extending protrusion receivable into the axially extending groove.

6. The flange of claim 5 , wherein at least two circumferentially spaced axially extending grooves are provided as one of the first and second coupling parts, and wherein at least two circumferentially spaced axially extending protrusions are provided as the other of the first and second coupling parts.

7. The flange of claim 6 , wherein the one of the first and second coupling parts that includes at least two circumferentially spaced axially extending grooves includes four axially circumferentially spaced extending grooves, and wherein the other of the first and second coupling parts that includes at least two circumferentially spaced axially extending protrusions includes four circumferentially spaced axially extending protrusions.

8. The flange of claim 1 , wherein the at least two generally arc-shaped locking element parts include a planar slanting contact surface.

9. The flange of claim 1 , wherein the annular flange body defines a circumferential outer surface.

10. A flange-hose assembly comprising:
the flange according to claim 1 ; and
a hose having an outer diameter smaller than an inner diameter of the central hose opening and larger than an inner diameter of the annular locking element, which hose has on an end a circumferential groove, in which the annular locking element is at least partially accommodated.

11. A flange for a hose comprising:
a) an annular flange body having a central hose opening;
b) an annular locking element for locking the annular flange body in a circumferential groove of a hose, which annular locking element is composed out of at least two generally arc-shaped locking element parts, wherein the annular locking element is concentrically arranged in the central hose opening of the annular flange body; and
c) couplings for each of the at least two generally arc-shaped locking element parts, wherein the couplings have a first coupling part arranged on the annular flange body and a second coupling part arranged on the respective arc-shaped locking element part, which first coupling part couples to the second coupling part;
d) wherein the first coupling part is a groove extending in axial direction from a first end surface of the annular flange body, wherein a length of the groove is smaller than a thickness of the annular flange body, and wherein the second coupling part is a protrusion arranged on a radially outer surface of the respective locking element part, which protrusion has in axial direction a cross-section corresponding to a cross-section of the groove;
e) wherein the cross-section of the protrusion and the cross-section of the groove are T-shaped.

12. The flange according to claim 11 , wherein an inner diameter of the annular locking element corresponds with an outer diameter of the circumferential groove of the hose.

13. The flange according to claim 11 , wherein the annular flange body has a number of axially extending through holes evenly positioned along the circumference of the annular flange body.

14. A flange-hose assembly comprising:
the flange according to claim 11 ; and
a hose having an outer diameter smaller than an inner diameter of the central hose opening and larger than an inner diameter of the annular locking element, which hose has on an end the circumferential groove, in which the annular locking element is at least partially accommodated.

15. A flange for a hose comprising:
an annular flange body having a central hose opening;
an annular locking element for locking the annular flange body in a circumferential groove of a hose, which annular locking element is composed out of at least two generally arc-shaped locking element parts, wherein the annular locking element is concentrically arranged in the central hose opening of the annular flange body; and
couplings for each of the at least two generally arc-shaped locking element parts, wherein the couplings have a first coupling part arranged on the annular flange body and a second coupling part arranged on the respective arc-shaped locking element part, which first coupling part couples to the second coupling part,
wherein at least two circumferentially spaced axially extending grooves are provided on one of the first and second coupling parts, and wherein at least two circumferentially spaced axially extending protrusions are provided on the other of the first and second coupling parts; and
wherein cross-sections of the circumferentially spaced axially extending protrusions and cross-sections of the circumferentially spaced axially extending grooves are T-shaped.
