Problems solved by technology

The failure mode can vary, but typically the failure is failure of the inner elastic tube, where the inner elastic tube ruptures at some point along its length, or failure of the connection between the inner elastic tube and a coupling

Embodiment Construction

[0055] Figure 1 to Figure 3 Schematically shows a hose arrangement comprising a hose assembly 1 provided at each end with a corresponding hose end part 2 (at figure 2 and image 3 only one of them can be seen in ). A hose set is a garden hose set which is used, for example, in a home garden for watering plants and / or cleaning surfaces. figure 1 The hose assembly is shown in a retracted state, which would tend to be assumed when there is no water in the hose assembly. on the other hand, figure 2 and image 3 shows the stretched figure 1 The part of a hose assembly that will tend to adopt this extended state when water flows through the hose assembly.

[0056] While this description refers to this type of garden hose, it is again noted that the concepts in this description apply more generally than this. They can be used, for example, in other types of water hoses in non-domestic situations, but also in other applications, such as industrial applications including pain...

Abstract

A hose arrangement comprising an outer tube (11) of flexible material and an inner tube (12) of an elastic material for carrying fluid through the hose arrangement, wherein due to the action of the elastic inner tube, the hose arrangement has a shorter length in a contracted state in the absence of fluid pressure in the interior of the inner elastic tube and a longer length in an expanded state when fluid pressure is applied to the interior of the elastic inner tube, and the outer tube has an undulating state when the hose arrangement is in the contracted state and serves to control and contain expansion of the inner tube when the hose arrangement is in the expanded state. The flexible material of the outer tube comprises a woven fabric which is woven from two types of yarn, a first type of yarn (9a) being of a first material and a second type of yarn (9b) being of a second material, which is different from the first material.

Description

technical field [0001] The present invention relates to hose fittings. Background technique [0002] The concepts in this specification are generally applicable to different types of hoses, including industrial hoses (eg, hoses used in spray painting applications) and watering hoses, including household hoses (eg, garden hoses). An example of a hose to which these concepts relate is a garden hose of the type that, when pressurized by water flowing through it, has an increased length that expands, and in the absence of such pressure Next, the hose has a retracted state. Although the use of such hoses is of particular interest in the field of garden hoses, these concepts may also be relevant in other situations where similar expansion hoses are used. [0003] One such prior expandable hose is described in GB 2490276A. The hose has an outer tube formed of a non-elastic and flexible material and an inner tube formed of an elastic material. The outer tube and the inner tube h...
