Description

Hose assembly

Technical Field

The utility model relates to a hose assembly, hose assembly includes inside hose and outside knitting each individual strand weaves together each other in the outside knitting, wherein, every individual strand has two piece at least monofilaments.

Background

Braids of this type are known in hose assemblies and are used, for example, for reinforcing hose assemblies, but also for visual design of hose assemblies.

SUMMERY OF THE UTILITY MODEL

The task of the utility model is to improve the service property of the hose assembly.

In order to solve the problem, according to the invention a hose assembly is specified, which comprises an inner hose and an outer braid in which individual wires are braided with one another, wherein each individual wire has at least two individual wires. In particular, in order to solve the problem, it is proposed according to the invention in the case of a hose assembly of the type mentioned at the outset that at least one individual wire of the individual wire has a non-circular limiting contour in cross section. This makes it possible to limit the optical reflection impression of the surface to a smaller area of the bounding contour and thus to achieve a visually attractive appearance. Thereby improving the use characteristics.

In an advantageous embodiment, it can be provided that the limiting contour defines an outer surface or an inner surface. Thereby, different design possibilities can be provided. The structuring on the outer surface may have the advantage that the light reflection immediately has an effect. The structuring on the inner surface may have the advantage that the tactile feel remains unchanged.

In an advantageous embodiment, it can be provided that the limiting contour delimits a non-circular cross-sectional contour. The non-circular limiting contour can thus be formed simply by shaping the monofilament.

In an advantageous embodiment, it can be provided that the bounding contour defines a polygon. This makes it possible to use monofilaments that can be produced particularly easily, in particular in an extrusion or extrusion process.

The polygon may be, for example, a straight-line bounded polygon. Thereby, a particularly sharp apex between the two faces can be used for concentration of the light reflection.

The polygon may be, for example, a polygon with rounded corners. This makes it possible for the light reflection to move on the filament if the filament is rotated about its longitudinal axis.

Specific examples of polygons that may be advantageously used include triangular, quadrangular, or polygonal polygons.

In an advantageous embodiment, it can be provided that at least two peripheral sections of the limiting contour have different curvatures from one another. Thereby, the light reflection can be freely concentrated and/or defined.

In an advantageous embodiment, it can be provided that the curvatures have different signs. Thereby, a free shape can be used. Furthermore, in the case of a movement of the individual filaments relative to the observer, a corresponding different variation of the light reflection can be achieved.

In an advantageous embodiment, it can be provided that the curvatures differ in value. Thereby, different degrees of concentration of light reflection can be achieved.

In an advantageous embodiment, it can be provided that the limiting contour has a concave recess. A simple means is thus described for achieving an alternation of curvature sign along the bounding contour.

For example, it can be provided that the cross-sectional contour has a concave depression.

The concave depression can be formed, for example, in one of the at least two peripheral sections.

In an advantageous embodiment, it can be provided that the limiting contour has a discrete or continuous rotational symmetry. In this way, a regular reflection impression can be achieved.

The limiting contour with discrete symmetry, in particular with two-, three-or four-fold symmetry, can be produced in a particularly simple manner with respect to the dimensions of the monofilaments by means of a die for extrusion. The low symmetry has the advantage of a simple structure, which poses little challenges for the die structure of an extrusion or extrusion die.

The discrete rotational symmetry can be characterized, for example, by: there are only a limited number of angles (multiples of the base angle) through which the bounding profile can be turned to coincide with itself.

For example, it can be provided that the cross-sectional profile has a discrete or continuous rotational symmetry.

In an advantageous embodiment, it can be provided that the limiting contour has at least mirror symmetry. This results in a symmetrical reflection impression.

For example, it can be provided that the cross-sectional profile has at least mirror symmetry.

In an advantageous embodiment, it can be provided that the limiting contour is in the form of an X, Y or star. This describes a limiting contour which allows a particularly balanced design of the curved sections, in particular if the edges on the monofilaments have a rounding.

For example, it can be provided that the cross-sectional contour is in the form of an X, Y or star.

In an advantageous embodiment, provision can be made for the inner braid to be formed inside the outer braid. Thereby, the mechanical load of the outer braid can be reduced and/or additional optical reflections can be generated.

In an advantageous embodiment, it can be provided that the monofilaments form a surface which is at least partially reflective. In this way, the light reflection can be configured to be particularly well visible.

For example, it can be provided that more than 50% of the surface is embodied to be reflective. It has been shown that particularly good looking reflection properties can be achieved with this type of surface.

In an advantageous embodiment, it can be provided that the limiting contour defines a hollow monofilament. This makes it possible to produce the inner surface usable in the present invention particularly easily.

For example, it can be provided that the cross-sectional contour defines a hollow monofilament.

In this case, it can be provided, in particular, that the at least one monofilament is made of a transparent material. Whereby the inner surface can be perceived from the outside.

Detailed Description

Fig. 1 shows a side view of a hose assembly according to the invention, which is designated as a whole by 1.

Fig. 2 to 4 show a detail of the hose assembly 1, which is only schematically illustrated in fig. 1.

The hose assembly 1 has an inner hose 2. The inner hose 2 is in the exemplary embodiment designed as a corrugated hose.

Furthermore, the hose assembly 1 has an outer braid 3 which is guided around the inner hose 2 and encloses it.

The hose assembly 1 can have a crimp sleeve 24 at least at one end, which connects the inner hose 2 and the outer braid 3 and/or is fixed to a hose connection 25, for example a hose nipple.

The outer braid 3 is woven by a plurality of single-wires 4, and each single-wire 4 is composed of a monofilament 5.

The individual filaments 5 extend substantially in the longitudinal direction (or parallel) and cross one another.

In the exemplary embodiment according to fig. 1 to 4, each individual wire 4 has four individual filaments 5.

Fig. 7 shows a cross section of the monofilament 5 in fig. 1 to 6.

The cross section is defined by a limiting contour 6 which is non-circularly formed relative to a center 7. For this purpose, the limiting contour 6 belongs to the outer surface 8 of the monofilament 5.

The cross-sectional shape determines that the limiting contour 6 has a plurality of peripheral portions 9, 10, 11 which form curvatures which differ from one another.

The peripheral sections 9 and 11 have curvature signs opposite to one another, wherein the curvature can be identical in value.

Furthermore, the peripheral sections 9 and 10 have the same sign of curvature, but have different curvatures in value.

This results in light reflections, i.e. a so-called concentration of light edges, in the peripheral sections 9, 10 with a curvature that increases in value.

The extent of the peripheral portion 9 can be described, for example, as a radius 12, while the peripheral portion 11 can be characterized, for example, by a concave recess 13.

Furthermore, it can be seen in fig. 7 that the cross-sectional profile 14 has a four-fold discrete rotational symmetry, in which case the cross-sectional profile 14 transforms into itself upon a rotation of 90 °.

Furthermore, there is mirror symmetry on the axis 15 shown.

Furthermore, the hose assembly 1 has an inner braid 16. The inner braid 16 is braided from strands 17, each of which consists of four individual filaments 18.

Fig. 8 shows that the monofilaments 18 of the inner braid 16 have a circular cross-section.

Fig. 5 and 6 show the

individual wires

4, 17 of the outer braid 3 and the inner braid 16, respectively.

Here, the inner braid 16 is disposed between the outer braid 3 and the inner hose 2.

In other embodiments, the monofilaments 5 are made of a partially or completely reflective material or are formed with a coating of this type.

Fig. 9 shows by way of example a series of delimiting profiles 6 for a monofilament 5 of a single strand 4.

Exemplarily showing: a polygon with flat sides and sharp vertices 20 configured in between (top left), a polygon with straight sides 19 and rounded corners 21 (top, second example from left), a polygon with curved edges 19 and rounded corners 21 (top, second example from right), a free shape 22 (top right), an ellipse (bottom left), an egg shape (bottom, second example from left), a square profile with only slightly rounded corners 21 (bottom, second example from right) and one further example of a free shape 22 (bottom right).

Fig. 10 shows another example set of possible delimiting profiles 6 of the monofilaments 5 of the hose assembly 1 according to the invention.

Fig. 11 shows two further limiting contours 6, which, unlike the preceding exemplary embodiment, describe an inner surface 23.

The monofilaments 5 are here made of a transparent material so that the inner surface 23 presents an outwardly concentrated light edge.

According to the invention, the hose assembly 1 has an inner hose 2 and an outer braid 3 which accommodates the inner hose 2, the outer braid 3 being braided from individual wires 4, wherein each individual wire 4 consists of two or four individual wires 5, it being provided in the hose assembly that at least one individual wire 5 forms a limiting contour 6, so that the limiting contour 6 forms differently curved peripheral sections 9, 10, 11.
