Definitions

  • the invention relates to a hose arrangement with an inner hose and an outer braid, in which the individual strands are braided together, with each individual strand having at least two filaments.
  • Braidings of this type are known in hose arrangements and are used, for example, for reinforcement but also for the visual design of hose arrangements.
  • the object of the invention is to improve the performance characteristics of a hose arrangement.
  • the boundary contour defines an outer surface or an inner surface. Different design options can thus be made available. Formation on an outer surface can have the advantage that light reflections have an immediate effect. A design on an inner surface can have the advantage that a haptic impression remains unchanged. In an advantageous embodiment it can be provided that the delimiting contour delimits a non-round cross-sectional profile. A non-round boundary contour can thus be formed simply by shaping the filament.
  • the boundary contour defines a polygon. Filaments that can be produced in a particularly simple manner, in particular in an extrusion molding or extrusion process, can thus be used.
  • the polygon can be, for example, a rectilinearly delimited polygon. In this way, particularly sharp vertices between two surfaces can be used for concentrating light reflections.
  • the polygon can be a polygon with rounded corners, for example. It is thus possible for a light reflection to migrate across the filament when it is rotated around its longitudinal axis.
  • polygons that can be used to advantage include a triangular, quadrangular, or polygonal polygon.
  • At least two peripheral sections of the delimiting contour have curvatures that differ from one another.
  • light reflections can be freely concentrated and/or defined.
  • the curvatures have different signs. This means that free forms can be used. In addition, a different change in the respective light reflections can be achieved when the filament moves relative to an observer. In an advantageous embodiment it can be provided that the curvatures are different in terms of absolute value. In this way, concentrations of the light reflections of different strengths can be achieved.
  • the delimiting contour has a concave indentation. A simple means is thus described for achieving alternating signs of the curvature along the boundary contour.
  • the cross-sectional profile has a concave indentation.
  • the concave indentation can be formed in one of the at least two peripheral sections, for example.
  • the delimiting contour has a discrete or continuous rotational symmetry. A regular reflection impression can thus be achieved.
  • Limiting contours with discrete symmetry are particularly easy to produce in the dimensions of the filaments on tools for extrusion.
  • a low symmetry has the advantage of simple structures that pose fewer challenges to the tooling of an extrusion or extrusion mold.
  • a discrete rotational symmetry can be characterized, for example, by the fact that there is only a finite number of angles (multiples of a basic angle) by which the boundary contour can be rotated in order to bring the boundary contour into congruence with itself.
  • the cross-sectional profile has a discrete or continuous rotational symmetry.
  • the delimiting contour has at least mirror symmetry. A symmetrical reflection impression can thus be created.
  • the cross-sectional profile has at least mirror symmetry.
  • the boundary contour is X-shaped, Y-shaped or star-shaped.
  • boundary contours are described that allow a particularly balanced formation of curved sections, in particular with rounded edges on the filament.
  • the cross-sectional profile is X-shaped, Y-shaped or star-shaped.
  • an inner braiding is formed within the outer braiding.
  • the external braiding can thus be relieved mechanically and/or additional optical reflections can be generated.
  • the filament is designed with an at least partially reflective surface.
  • a light reflection can thus be formed in a particularly easily visible manner.
  • the surface is designed to be more than 50% reflective. It has been found that a particularly good-looking reflection behavior can be achieved with such surfaces.
  • the boundary contour defines a hollow filament. Inner surfaces that can be used for the invention are thus particularly easy to create.
  • the cross-sectional profile defines a hollow filament.
  • the at least one filament is made of a transparent material. This means that inner surfaces can be seen from the outside.

  • FIG. 1 shows a hose arrangement according to the invention, designated as a whole by 1, in a view from one side.
  • FIGS. 2 to 4 show sections of the hose arrangement 1 shown only schematically in FIG.
  • the hose arrangement 1 has an inner hose 2 .
  • the inner hose 2 is designed as a corrugated hose.
  • the hose assembly 1 further has an outer braid 3 which is routed around and encloses the inner hose 2 .
  • the hose assembly 1 can at least at one end Have crimp sleeve 24, which connects the inner hose 2 and the outer braid 3 and / or is fixed to a hose connector 25, such as a hose nipple.
  • the outer braiding 3 is braided from a large number of individual strands 4 which are each composed of filaments 5 .
  • the filaments 5 run essentially longitudinally (or parallel) and cross one another.
  • each individual strand 4 has four filaments 5.
  • Figure 7 shows a cross section through a filament 5 from Figures 1 to 6.
  • the cross section is defined by a boundary contour 6 which is non-circular in relation to a center 7 .
  • the boundary contour 6 belongs to an outer surface 8 of the filament 5.
  • the cross-sectional shape means that the boundary contour 6 has a plurality of peripheral sections 9, 10, 11, which form curvatures that differ from one another.
  • peripheral sections 9 and 11 have opposite signs of the curvatures to one another, it being possible for the curvatures to match in terms of amount.
  • peripheral sections 9 and 10 have the same mathematical sign of the curvature, but have different amounts of curvature. This results in the concentration of light reflections, the so-called light edges, in the peripheral sections 9, 11 with an increased amount of curvature.
  • peripheral section 9 can be described as a rounding 12, for example, the peripheral section 11 could be characterized as a concave indentation 13, for example.
  • cross-sectional profile 14 has a four-fold discrete rotational symmetry, in which the cross-sectional profile 14 is converted into itself when rotated by 90°.
  • the hose assemblies 1 further have an inner braid 16 .
  • the inner braiding 16 is braided from strands 17 which are each composed of four filaments 18 .
  • FIG. 8 shows that the filaments 18 of the inner braiding 16 have a round cross section.
  • Figures 5 and 6 each show a single strand 4, 17 of the outer braiding 3 or. of the inner braid 16 .
  • the inner braiding 16 is here arranged between the outer braiding 3 and the inner hose 2 .
