Definitions

  • the invention relates to a shock-absorbing spacer arrangement, suitable for arrangement between spaced apart, relatively flexible and / or movable surfaces, for example for arrangement between an inner and an outer sole of a shoe.
  • a midsole provided between an inner and an outer sole of a shoe can consist essentially of two spaced apart, relatively stiff fabric layers, between which fabric webs formed as X-shaped profiles, which are interwoven with the aforementioned fabric layers, are arranged as spacer elements.
  • the fabrics can be made of polypropylene, polyvinyl or polyester, for example.
  • shock-absorbing shoe sole which consists essentially of an undersole with a wavy upper surface and an upper sole with a wavy underside, the concave zones of the corrugated structure of the lower sole absorbing the convex zones of the corrugated structure of the upper sole.
  • Different wave forms or corresponding spacing elements ensure that the elle ⁇ structures load one another primarily on the wave flanks and are apart from one another, at least in the unloaded state. This is to ensure that the shaft structures made of elastomer material are subjected to pronounced shear stress when the sole is loaded in the region of the shaft flanks and that there is good compliance.
  • the object of the invention is now to provide a shock-absorbing spacer arrangement, the damping and suspension properties of which can be specified within an extremely wide range, and furthermore a low weight and good air circulation should be possible.
  • This object is achieved according to the invention by a flexible supporting structure part with open arches arranged next to and / or one behind the other in a grid-like manner over a base area and arranged in a corresponding grid, the openings penetrating the base area at least below the arches.
  • the invention is based on the general idea of arranging deformable supporting arches in a grid-like connection with one another.
  • a load on the middle of the bow leads to a corresponding deformation of the arch, the side parts of the arch being pushed sideways and forming shortened pillar-like supports with a relatively high load capacity in comparison to the height of the unloaded arch.
  • a markedly progressively increasing resistance is made possible in relation to a loaded surface resting on the arches, ie, despite the initially high flexibility, a high load-bearing capacity is possible without excessive deformation.
  • the spacer arrangement according to the invention can be used between the outer and inner sole of a shoe.
  • the spacer arrangement can also be used for protectors, e.g. B. knee or elbow pads, or to use stiffenable or flexible hollow body.
  • the arches are arranged side by side in rows of arcs transverse to the arc axis.
  • each foot zone between adjacent arches of a row of arches with one foot zone between adjacent arches of the adjacent row of arches or rows of arches via narrow, flexible webs. This gives the foot zones of each row of arches a comparatively great flexibility in the longitudinal direction of the row of arches.
  • a plate part which has a lattice structure with windows arranged in a grid pattern corresponding to the arches of the supporting structure part, concavities or convexities being formed on the lattice webs, in or on which the foot zones of the arches of the supporting structure part and / or whose webs are held in place by positive locking.
  • the plate part can be made of flexible, but essentially inextensible material, while the supporting structure part is formed from an elastomer or the like. With such a composite construction, very different ensure load capacities.
  • one of the rows of sheets stacked one on top of the other in the direction of the sheet axes has comparatively wide sheets with windows arranged in the sheet cut sections, the sheet center sections of the opposite sheet row, the sheets of which in the direction of the sheet axes have a window width have the appropriate width, record.
  • the rows of arches of the two supporting structure parts engage in one another in a form-fitting manner, so that between the surfaces spaced apart by the spacer arrangement, surface-parallel forces can also be transmitted with corresponding deformation of the arches if the spaced surfaces are fixed with the base surfaces of the supporting structure parts or are non-slip connected.
  • the arches of a supporting structure part of a spacer arrangement can also be designed as cross arches, that is to say as a composite of two crossing arches.
  • a further spacer arrangement for which separate protection is claimed, is characterized in that a structural part designed in the manner of a link belt is provided.
  • Each link of this link band can have an essentially circular profile piping and a parallel C-profile with a C opening facing away from the piping, the C-profile of one link positively receiving or capable of receiving the piping of the neighboring link.
  • Such an arrangement is extremely flexible in bending movements with respect to the keder axes, as long as the connections of a link between the keder and the C-profile do not interact with the edges of the C-opening of the next link as far as it will go.
  • the link band has a different shape, if his limbs are pushed in one direction or another by external forces into the respective stop position. Since the links are made of resilient material, the link belt can be urged resiliently beyond the stop position even when its links have reached a stop position.
  • FIG. 1 shows a perspective view of the heel-side half of a shoe sole arrangement with a spacer arrangement according to the invention between a foot shell or insole and an outsole or an outsole support, [031] FIG.
  • Fig. 2 is a side view of the shoe sole assembly shown in Fig. 1 with a trim sheet including the spacer assembly omitted.
  • FIG. 3 shows a perspective view of a supporting structure part arranged on the outsole or the outsole carrier
  • FIG. 6 shows a perspective view of a supporting structure part arranged under the foot shell or inner sole
  • FIG. 9 is a perspective view of a further supporting structure part
  • FIG. 11 is a perspective view of a grid-like plate part which can be attached under the supporting structure part of FIGS. 9 and 10, [041] FIG.
  • FIG. 14 is a perspective view of a further supporting structure part with the same Base surface covering grid-like plate part,
  • FIG. 17 shows a further embodiment for a supporting structure part of a spacer arrangement
  • FIG. 21 shows a structural or skeleton part of a spacer arrangement
  • FIG. 23 shows a side view of a spacer device designed as a link belt
  • FIG. 24 is a top view of the spacer device of FIG. 23,
  • FIG. 26 is a perspective sectional view of this damping mat.
  • a sports shoe (not shown in detail) has, at least within a shoe area near the heel, a foot shell-like insole 1 and an outsole 2 which is vertically spaced apart in a zone near the heel, the underside of which is designed as a tread or is covered with a tread layer.
  • a spacer arrangement Arranged between the insole 1 and the outsole 2 is a spacer arrangement, which is explained in more detail below and which is suitable for absorbing greater pressure forces in a shock-absorbing manner.
  • This spacer arrangement which is explained further below, is enclosed by an optionally transparent cover film 3, which is attached to the edges of the insole 1 and the outsole 2 and determines the maximum distance between the insole 1 and the outsole 2.
  • the cover film 3 is flexible in relation to the draining forces between the soles 1 and 2.
  • the inner sole 1 and the outer sole 2 can each be designed to be flexible, but with greater rigidity, so that punctual loads are always transferred to larger areas of the respective sole.
  • a web 4 is formed, which encloses a rectangular surface covering the entire heel area on the underside of the insole 1.
  • a similar web 5 is arranged on the upper side of the outsole, the height of which, however, is significantly less than the height of the web 4.
  • the web 5 has a rectangular U-shape in a plan view of the upper side of the outsole 2, the mutually parallel U-legs extending into the middle region of the shoe being connected to one another at the distal end of the outsole 2 by a transverse section of the web 5 , [061]
  • This supporting structure part 6 which is formed from rigid, flexible material, has a base surface 7 glued to the outsole 2, on which open arches 8 to 10 are arranged in a grid-like manner, under which the base surface 7 is penetrated by rectangular windows 11, which means the aforementioned windows 11 are arched by the arches 8 to 10.
  • the arches 8 to 10 are arranged in three parallel rows of arches, each consisting of arches arranged next to one another transversely to the arc axis.
  • each row of sheets comprises three sheets 8 with a medium span, one sheet 9 with a large span and a small sheet 10 with a small span. All the arches 8 to 10 have the same width in the direction of the arch axis, but the arches 8 are each provided with rectangular windows 12 in the central region of the arch.
  • the base surface 7 forms bands which run parallel to the rows of arches and which are in perfect alignment with one another at the foot regions of arches 8 to 10, that is to say at the “abutments” of arches 8 to 10 are connected.
  • the supporting structure part 6 is arranged on the upper side of the outsole 2 such that the arches 8 are arranged on the heel side of the arches 9 and the arches 10 on the toe side of the arches 9.
  • a further supporting structure part 13 is arranged on the surface surrounded by the web 4 on the underside of the insole 1, which is shown in more detail in FIGS. 6 to 8.
  • This supporting structure part 13 has a base surface 14 surrounded by the web 4 and glued to the underside of the insole 1, on which similar open arches 15 are arranged next to one another in three parallel rows of arches, the arches 15 in turn arching rectangular windows 16 penetrating the base surface 14.
  • the base surface 14 thus forms strip-like bands which run continuously between the rows of arches and laterally next to the two outer rows of arches and which are integrally connected to one another in the transverse direction at the arch feet or abutments.
  • the further supporting structure part 13 is also formed from a tough, rigid and flexible plastic.
  • the arches 15 In the axial direction, the arches 15 have a width which corresponds to the width of the windows 12 in the arches 8 of the first supporting structure part 6 on the outsole 2.

  • the arches 15 of the supporting structure part 13 engaging in the windows 12 of the arches 8 of the supporting structure part 6 on the outer sole 2 deform the insole 1 in the shape of an ogive, the limbs of the arches 8 being pushed somewhat to the side at the edges of the windows 12 parallel to the arc axis.

  • the supporting structure part 17 shown in FIGS. 9 and 10 has a multiplicity of parallel rows of arches with similar open arches 18, with adjacent rows of arches being offset from one another in the longitudinal direction of the rows by half an arc span.
