Definitions

  • the invention relates to a network, in particular a spacer network, surface protection network or the like, with intersecting strands.
  • the networks mentioned here are mainly used as spacer networks or surface protection networks. These consist of two layers of intersecting strands. For the secure packaging of goods or the spacing of objects, the network must have a certain thickness, which is achieved in known networks of this type by the correspondingly large dimensioning of the cross section of the strands. These networks require a lot of material. In addition, they have very limited suspension properties.
  • the invention has for its object to provide a network of the type described above, which has the requirements placed in particular on spacer networks or surface protection networks.
  • the object is achieved in that the strands of the network are arranged in three different levels and the strands of two levels are rectified.
  • a relatively large network thickness with a small cross-section (minimal material expenditure) of the individual strands is achieved and the suspension properties of the network are improved.
  • the strands of two outer planes preferably run parallel to one another so that the outer strands do not cross one another, thereby avoiding partial differences in the thickness of the network.
  • the outer strands of the outer planes are offset parallel to one another in the longitudinal direction of the strands (inner strands) of the middle plane. This results in surprisingly good suspension properties of the network.
  • the inner strands are elastically deformable in such a way that the outer strands are movable in the direction of the central plane of the inner strands. If the outer strands are acted upon in the direction of the middle plane and thus the inner strands, the outer strands move to a certain extent into the middle plane or between the inner strands.
  • the good elastic properties of the net are based on the associated elastic deformation of at least the inner strands, which ultimately ensures good upholstery of the goods encased thereby or the distance between two objects separated by the net can be changed.
  • the suspension properties of the network depend in particular on the distance by which the outer strands of different outer planes are offset from one another in the longitudinal direction of the inner strands, which is why the distance is precisely defined in accordance with the invention. It applies that the suspension is the harder, the smaller the distance between outer strands of different levels.
  • the suspension of the net is particularly soft. Of course, this applies in particular if the distances between adjacent outer strands are the same in both outer planes.
  • the net in particular plates of latent heat storage.
  • the latter change their thickness as a result of temperature fluctuations, and the resulting changes in the mutual spacing of the plates can be compensated for by the network according to the invention, by virtue of its configuration according to the invention being able to change its thickness elastically to the extent necessary.
  • a network 10 shown in FIGS. 1 to 3 has three different levels 11, 12, 13, which are indicated by dash-dotted lines in the figures. These levels 11, 12, 13 extend parallel to one another, one of the outer levels 11, 13 being arranged on opposite sides of the middle level 12.
  • inner strands 14 extend essentially parallel and with a uniform mutual spacing in the middle plane 12
  • outer strands 15, 16 which run in the same direction are arranged in the outer planes 11, 13.
  • the outer strands 15, 16 intersect with the inner strands 14, preferably at an angle less than or greater than 90 °, in particular 75 °.
  • the outer strands 15, 16 are connected to the inner strands 14 at the crossing points.
  • the outer strands 15, 16 are distributed over the outer levels 11, 13.
  • the outer strands 15 in the plane 11 run in the same way as the outer strands 16 in the plane 13.
  • the inner strands 14 and outer strands 15, 16 have the same distance.
  • the outer strands 15 and 16 of the different outer levels 11 and 13 are aligned in parallel.
  • the inner strands 14 as well as the outer strands 15, 16 have an essentially straight course, which is expedient for manufacturing reasons, but also with regard to the mechanical properties of the network 10.
  • the network 10 When the network 10 is loaded by tension in the direction of the outer strands 15, 16 or inner strands 14, this has good stability.
  • the parallel outer strands 15, 16 of the different outer planes 11, 13 are arranged offset to one another in the longitudinal direction of the inner strands 14. This is of particular importance for the suspension properties of the net 10. If a force is applied to the outer strands 15 of the outer plane 11 in the direction of the plane 12, this results in a relative movement of the outer strands 15, 16 and a deformation of the inner strands 14. The outer strands 15, 16 move in the direction of the inner strands 14 with simultaneous elastic deformation of the inner strands 14, which assume an undulating course (FIGS. 3 and 5).
  • the relative movement of the network 10, 17 when the same is applied between two flat surfaces, not shown, can be seen.
  • the network 10, 17 is shown in an almost "blocked" position, in which the distance between the surfaces mentioned is equal to the sum of the diameters of two strands (inner strands 14 or outer strands 15, 16).
  • the suspension properties of the net 10 depend essentially on the distance by which the outer strands 15 of the outer plane 11 are offset from the outer strands 16 of the outer plane 13. If the distance is small (see FIGS. 1 to 3), the suspension of the net 10 is relatively hard.
  • the suspension of a network 17 is soft.
  • the mutual distances of the outer strands 15 and 16 of the respective outer plane 11 and 13 are the same, but the outer plane 13 has twice the number of strands 16 compared to the outer plane 11.
  • the mutual distances between the outer strands 16 of the outer plane 13 are such that two of the outer strands 16 of the outer plane 13 are always arranged between two adjacent outer strands 15 of the outer plane 11.
  • Inner strands 14 are also deformed in a wave-like manner.
  • the deformation of the inner strands 14 around the outer strands 15 is, however, greater than the deformation of the inner strands 14 around the outer strands 16.
  • the suspension of the net 18 thus formed is harder than in the exemplary embodiments described above.
  • a network 19 shown in Fig. 7 the distances between the outer strands 16 of the outer plane 13 are changed such that two of the outer strands 16 are alternately arranged between two of the adjacent outer strands 15 of the outer plane 11, while the outer plane 13 in the area between the next two outer strands 15 of the outer plane 11 is free of the outer strands 16.
  • This net 19 has partially different suspension properties, the suspension being harder where the outer strands 16 are arranged between the outer strands 15.
  • the outer strands 15 and outer strands 16 likewise run in the same direction or parallel to one another, but they are essentially congruent with one another and are therefore not offset in the longitudinal direction of the inner strands 14.
  • This net 20 has only low suspension properties. However, it enables a constant and relatively large distance between the goods or objects to be kept at a distance with a small cross-section of the individual outer strands 15, 16 and inner strands 14.
  • the outer strands 15, 16 and inner strands 14 of the nets 10, 17, 18, 19 and 20 shown here preferably have circular and equally large cross sections.
  • the cross section of the inner strands 14 can, however, also be larger or smaller than that of the outer strands 15, 16 in order to change the suspension properties, the suspension being the harder the larger the cross section of the inner strands 14 and vice versa.
  • the outer strands 15, 16 and / or inner strands 14 can also have other cross sections (for example square, elliptical, etc.).
  • the networks 10, 17, 18, 19 and 20 are tubular.
  • the tubular nets 10, 17, 18, 19 and 20 can easily be pulled onto the goods to be protected or the objects to be spaced apart, in particular plates.
  • the three-layer design of the nets provides reliable protection of the goods against damage.
  • the tubular nets 10, 17, 18 and 19, which are elastically variable in thickness, also offer good padding for the wrapped goods.
  • the elastic suspension properties serve to compensate for changes in the thickness of the heat storage plates caused by temperature changes. For this purpose, the nets 10, 17, 18 and 19 are compressed as the thickness of the heat storage plates increases.
  • the outer strands 15 and 16 of the two outer levels 11, 13 have such a grid that they always run adjacent to the corners or edges of the heat storage plates. This ensures a secure, slip-free hold of the tubular nets 10, 17, 18 and 19 on the heat storage plates.
