Abstract
Abstract An elongated milking hose for a quarter milking machine. The milking hose has four elongated, flexible conduits, of which two conduits are connected to one another along a first common connecting segment, extending parallel with respect to the longitudinal axis of the hose. The two other conduits are each arranged on opposite sides of the first connecting segment of the two first conduits and extend parallel therewith and are each connected to the two first conduits along a second and third, and fourth and fifth connecting segment.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
145 words
In a unitary and flexible hose arrangement having at least four separate tubular conduits therethrough, said tubular conduits extending parallel to one another, the improvement comprising wherein the central longitudinal axes of said four tubular conduits each lie substantially at the corners of a rhombus, wherein each of said four tubular conduits are held together by a connection means between the mutually adjacent segments of each of said tubular conduits, said connection means extending over the entire length of said hose arrangement, and wherein at least two further passageways, separate from each of said four tubular conduits, are provided in said hose arrangement one each between three of said connections means between the two sets of three of said mutually adjacent segments of said tubular conduits on opposite sides of the minor axis of said rhombus, said hose arrangement thereby having a greater flexibility characteristic.
Claim 2
Dependent Claim
145 words
In a unitary and flexible hose arrangement having at least four separate tubular conduits therethrough, said tubular conduits extending parallel to one another, the improvement comprising wherein the central longitudinal axes of said four tubular conduits each lie substantially at the corners of a rhombus, wherein each of said four tubular conduits are held together by a connection means between the mutually adjacent segments of each of said tubular conduits, said connection means extending over the entire length of said hose arrangement, and wherein at least two further passageways, separate from each of said four tubular conduits, are provided in said hose arrangement one each between three of said connections means between the two sets of three of said mutually adjacent segments of said tubular conduits on opposite sides of the minor axis of said rhombus, said hose arrangement thereby having a greater flexibility characteristic.
Claim 3
Dependent Claim
25 words
The milking hose according to claim 1, wherein said connecting means are constructed as thin as possible to increase the flexibility of said hose arrangement.
Claim 4
Dependent Claim
20 words
The milking hose according to claim 1, wherein said conduits are with their respective connecting means extruded in one piece.
Claim 5
Dependent Claim
110 words
An elongated milking hose for a quarter milking machine, comprising: an elongated hose body which is manufactured by the extrusion method in one piece and has four separate passageways with a substantially equal inner cross-sectional area, the central longitudinal axes of the passageways being located substantially at the corners of an equilateral rhombus; and at least two additional passageways separate from the remaining four passageways, the cross sectional areas of each of said additional passageways which lies within the area defined by said equilateral rhombus, said milking hose thereby having a greater flexibility characteristic about a minor axis thereof than about a major axis to facilitate an easy use thereof.
Claim 6
Dependent Claim
110 words
An elongated milking hose for a quarter milking machine, comprising: an elongated hose body which is manufactured by the extrusion method in one piece and has four separate passageways with a substantially equal inner cross-sectional area, the central longitudinal axes of the passageways being located substantially at the corners of an equilateral rhombus; and at least two additional passageways separate from the remaining four passageways, the cross sectional areas of each of said additional passageways which lies within the area defined by said equilateral rhombus, said milking hose thereby having a greater flexibility characteristic about a minor axis thereof than about a major axis to facilitate an easy use thereof.
Claim 7
Dependent Claim
35 words
The milking hose according to claim 1 or claim 4, wherein each of said connecting means is severable to facilitate a separation of the ends of selected ones of said conduits from said hose arrangement.
