1 4 NAME(S) OF INVENTOR(S) KARL WEINHOLD ADDRESS FOR SERVICE: DAVIES COLLISON, Patent Attorneys I Little Collins Street, Melbourne, 3000., COMPLETE SPECIFICATION FOR THE INVENTION ENTITLED: "HOSE COUPLING" The following statement is a full description of this invention, including the best method of performing it known to mej West Germany Signature of declarant(s) (no alitesation required) Note Initial all alterations I)AVIlS COLLISON, MELBOURN and CAAN Weinhold) -2- This invention relates to a hose coupling. Hose couplings of the kind specified and having insert connections are known, for example, for DIN 20043. These prior art hose couplings having insert connections have the disadvantage that their stability is inadequate to withstand either the prevailing pressures on the line or external mechanical loadings. More particularly, prior art hose couplings having insert connections frequently rupture under pulsating surges, such as often occur in high pressure lines. Weak places include the coupling ao o o 02 5 clamp, but also the place where the pressure sleeve *oQ engages with the socket. Another unsatisfactory aspect 0 Sis the buckling strength of prior art hose couplings O 00 0 15 having insert connections. When hose couplings are used Os under ground, rocks often drop onto the coupling or somebody accidentally steps on the coupling. Under such o loads known insert couplings often break.
An object of the invention is therefore to provide a hose coupling being stable enough to withstand both increased external mechanical loadings, pulsating surges 0000 transmitted by the medium in the line, and high internal pressure.
0 The invention accordingly provides a hose coupling component which includes an insert sleeve having a first .0 portion adapted for insertion into a hose and a second portion which defines a peripheral surface for engagement with a complementary surface of a matching coupling component. A pressure sleeve is adapted to be disposed concentrically around the first portion of the insert sleeve for retaining a hose therebetween. Complementary rib means and groove means are provided on the interior of.the pressure sleeve and the exterior of the insert sleeve. These rib means and groove means are engageable 910115mmsp006a:\hosewgjcap,2 -3to secure the pressure sleeve and insert sleeve against substantial relative axial displacement. Means is provided on the pressure sleeve for positively coupling the pressure sleeve to the matching coupling component.
In a preferred embodiment, the rib means and the groove means respectively comprise an internal annular rib on the pressure sleeve and a complementary annular groove on the external surface of the insert sleeve.
A peripheral seal may be provided on the aforementioned peripheral surface of the insert sleeve.
0 r In an embodiment, the positive coupling means may 15 comprise a flange which is adapted to be received within an enlarged bore portion of the matching coupling component. The pressure sleeve may be adapted to concentrically receive the matching coupling component and may include one or more transverse passages to seat a coupling element for securing the pressure sleeve to the :matching coupling component. The coupling element may comprise, for example a U-shaped coupling clamp.
The invention also extends to a hose coupling comprising a hose coupling component as described above, and a further coupling component having a second peripheral surface to engage the first-mentioned 4 peripheral surface of the second portion of the insert sleeve.
The invention will now be further described, by way of example only, with reference to the accompanying drawings, in which: Fig. 1 is a longitudinal section through an embodiment of hose coupling including a coupling component according to the invention; f910115,inmspe.006,a:\hosegjncap,3

The hose coupling depicted in Figs. 1 to 3 includes a hose coupling component 30 according to a first embodiment of the invention and a matching coupling component 32. Component 30 includes an insert sleeve 31 having an externally uneven and relatively thin first portion 2 adapted for insertion into a hose 1, and a pressure sleeve 11 adapted to be disposed concentrically around the first portion 2 of insert sleeve 31 for a4 'a retaining hose 1. Hose 1 is compressed between the pressure sleeve and the insert sleeve, the latter being *provided with internal ribbing to further facilitate a e 15 firm grip.
0 4 Insert sleeve 31 includes a second relatively thicker walled portion 3, including an end part 4 which projects from the pressure sleeve for receipt by an intermediate enlarged bore portion 7 of matching component 32. Component 32 is generally in the form of a socket and includes a still more enlarged bore portion which receives pressure sleeve 11.
S1 25 End part 4 has a slightly tapered end and defines a cylindrical surface 36 for sliding engagement with the internal peripheral surface 38 of enlarged bore portion t 7. An annular seal 6 in a groove 5 in end part 4 of insert sleeve 31 seals the gap between peripheral surface 36 and bore surface 38. A shallow annular shoulder 37 on the portion 3 of insert sleeve 31 abuts the end surface of enlarged bore portion 35 and thereby ensures a gap between end part 4 and the end surface 9 of bore portion 7. By virtue of gap 10, the pressure medium flowing through the hose coupling exerts a force on both ends of insert sleeve 31. These oppositely directed forces 9101 15jnmrspe006,a -6balance so that the insert sleeve 31 is mounted in the hose coupling substantially free from axially directed forces.
The shape of pressure sleeve 11 in its initial state prior to application to the coupling is shown in Fig. 3.
It will be seen that the outer end is expanded outwardly about the second portion 3 of sleeve insert 31. This outer end is provided with an integral annular flange 14 of outer diameter, when in situ, substantially equal to the internal diameter of enlarged bore portion 35. The pressure sleeve is coupled to component 32 by a U-shaped 4 coupling clamp 15 fitted behind flange 14 through a pair of complementary transverse passages 16 in coupling ,r 15 component 32, dimensioned to firmly seat clamp 15. It will be seen that clamp 15 fixes flange 14 between the F front face of the clamp and the end surface of enlarged f V i bore portion For securing pressure sleeve 11 to insert sleeve 31, an integral internal rib 12 on the pressure sleeve engages a complementary annular groove 13 formed in the insert sleeve adjacent the rear of second portion 3. The engagement between rib 12 and groove 13 is effective to secure the two sleeves against substantial relative axial displacement, and is positive in both directions so as to t resist axial separation forces in either direction.
|i ,Various further embodiments of coupling and coupling component are shown in Figs. 4 to 22, in which like parts are indicated by like reference numerals. The embodiment of Figs. 4 and 5 entails similar general engagements between the parts but, in this case, the coupling component 32 is in male relationship to both insert sleeve 31 and pressure sleeve 11i, instead of being a socket to both as in the embodiment of Figs. 1 to 3.
910115inmispe.006,a:hosegjcap,6 -7- Thus, coupling component 32 has an end part 4a with peripheral seal 6 received within an enlarged bore portion 7a of second or outer portion 3 of insert sleeve 31. Furthermore, pressure sleeve 11 is stepped about both outer portion 3 of the insert sleeve and an integral annular flange 14a of the component 32, and the U-shaped coupling clamp 15 projects through transverse passages 16 intersecting an enlarged bore portion 35a of pressure sleeve 11. Again, the outer diameter of flange 14a is substantially equal to the internal diameter of enlarged bore portion 35a. It will be seen from Fig. 5 that, again, pressure sleeve 11 has a slightly different shape prior to application to the coupling, which shape is expanded radially outwardly during application.
4* ist The embodiment of Figs. 6 to 8 differs from those of tFigs. 1 and 4 in that the interengaged peripheral sealing surfaces 36,38 are tapered, and in that the means of securing the pressure sleeve 11 and'component 32 is quite different. More particularly, a flared end portion 18 of pressure sleeve 11 has an internal annular lip 22 which seats in a complementary annular groove 21 on the external surface of component 32. As illustrated in Fig.
8, this seating is effected by so relating the external surface of component 32 in the internal surface of flared portion 18 that the latter is deformed inwardly to bring lip 22 into groove 21.
The embodiment of Figs. 9 to 11 is similar to that of Figs. 6 to 8 except that the engaging peripheral surfaces 36,38 are generally cylindrical rather than tapered. Figs. 12 to 14 depict a variation of the embodiment of Figs. 9 to 11 in which the component 32 and pressure sleeve 11 are secured by threaded engagement between an internal thread on an enlarged end socket portion 18 of sleeve 11 and an externally threaded end S910115,imnspe.006:a\hosegjncap,7 i i j i i -8portion 32a of component 32. Portion 32a contains the enlarged bore portion 7 defining surface 38. The embodiment of Figs. 15 to 17 is a similar modification of that of Figs. 6 to 8.
In the embodiment of Fig. 18, the peripheral surface 36 of end portion 4 with annular seal 6 does not extend into the matching coupling component (not shown) but instead engages a complementary internal peripheral surface 38a of an enlarged bore portion of the pressure sleeve 11. It will be noted that the internal rib 12 and .groove 13 are still present, and that the pressure sleeve o 11 has an externally threaded end portion 23 for engaging an internally threaded socket portion of the other 15 coupling component (not shown).
0 90 ,o Figs. 19 to 22 respectively show, on the right, a fragmentary view of the coupling components of Figs. 6, 9, 12 and 15, in an arrangement in which the matching coupling component is a fitting nipple bearing with a union nut via which a connection is made to a further *i complementary hose coupling component (not shown).
