Definitions

  • the present invention relates to a shaped foot sole which forms a cup-shaped foot bed and consists of a bedding material which is softer and more elastic than the material of an outsole to be used, the foot bed in an upper fully plastic section of the top of the shaped foot sole essentially in the form of complementary curvature of the foot to be supported laterally up to a certain height, and wherein the shaped sole of the foot has a substantially flat bottom side to be connected to the upper side of the outer outsole of a shoe, and wherein the shaped sole of the foot has a lateral outer surface which, at an angle, runs at an angle from the vertical to the bottom side and extends at least partially in this way, and / or the shaped sole of the foot has a lateral outer wall that runs upwards in the vertical direction to the bottom side and at least partially surrounds it, or composite construction of such a shaped sole and an outer outsole.
  • Such shaped foot soles have a tread for the foot on their top, which is bowl-shaped Footbed is formed, thus it has beads and depressions, which form individual shell shapes for the heel area, ball area, toe area, forefoot, midfoot and the longitudinal arch of the foot in the longitudinal and transverse directions of the footbed.
  • the entire foot surface which is directed downwards or visible from below in a vertical projection, is supported by the side shells of the foot bed both from below and from the side.
  • the side shells of the footbed In the upper side area of the tread, in particular, the side shells of the footbed have almost vertically sloping inner side walls with steeply sloping footbed edges.
  • the foot bed contributes to the fact that the limbs and bones of the foot are held in their natural anatomical position during the static and dynamic forces that become effective when walking and standing, or are gradually brought back into such a position. Since the foot bed keeps the foot in its natural position, weakened muscles of the foot are strengthened so that they can keep the foot in its original shape.
  • the material of such known molded foot soles is relatively soft and elastic in spite of the necessary dimensional stability of the formed shell shapes, with 90% by weight natural cork with natural latex being processed into a very flexible, light and soft cork / latex sole in a known molded foot sole, which provides a high support effect Has foot bedding.
  • This shaped foot sole is laminated from above and below with jute and linen support fabric to stabilize the very sensitive cork material. In addition, this cork-shaped sole is covered with suede.
  • Such molded foot soles are used both in sandals and in shoes, especially health shoes. They are also used as orthopedic foot and shoe insoles, whereby they form fully plastic insoles from composite materials, in the surface of which the cup-shaped foot bed is molded.
  • Such shaped soles are disadvantageous in that they have steep footbed edges, which are supported ineffectively to the outside, so that the side panels of the footbed during the dynamic loading of the footbed are stressed and deformed to a considerable extent by the then occurring horizontal forces. Since the known shaped insoles of the foot essentially only permit vertical support of the foot under static load, that is to say while standing, this resulting support is very often unsatisfactory, particularly on inclined or uneven ground. The pressure concentrations on the outer edge areas of both the molded sole and the outsole are extremely high due to the vertical support when such lateral loads occur. The material of the shaped sole of the foot is exposed to considerable stresses from rolling and bending in the region of the side edges that taper to a point, so that, despite its inherent flexibility and elasticity, it can finally be partially destroyed.
  • a molded foot sole of the type mentioned which has a soft and elastic bedding material and a lateral, angled from the vertical to the bottom side, at least partially on the outside has circumferential outer wall, which supports the soft elastic bedding material laterally outwards.
  • the shaped foot sole is made of an upper sole that has the bedding material and a lower sole, which has a firmer material and thereby supports the soft bedding material of the upper sole of the foot bed downwards and laterally.
  • This firmer material forms a lateral support surrounding the upper sole in a shape that is supported at an angle to the outside.
  • lateral support inserts are also incorporated. It is also envisaged to form the sole of the foot from a total of 3 layers, wherein shock-absorbing inserts are to be applied within the sole of the foot.
  • the shaped foot sole is stabilized primarily by a multi-layered design of the shaped foot sole, whereby in addition to the soft bedding material, firmer materials, supports and inserts are used. Since this international application is only an older application compared to the present invention, although this must differ in terms of its subject matter from the subject matter of the earlier application, it does not require any additional inventive step for patentability.
  • the US patent 4,676,010 which has also been researched into the prior art, relates to a "wedge sole" for sports shoes and the like. That is to say, not an actual shaped sole which is to be put on above the outsole and which has a cup-shaped footbed to support the foot.
  • the lateral bevel of the wedge sole according to US Pat. No. 4,676,010 is only effective as a lateral support below or approximately at the level of the tread surface. Although this causes a widening of the sole, the foot is not supported laterally within a footbed, in particular no lateral support of the edges of the footbed is thereby achieved.
  • a "shoe sole” is also already known.
  • the upper component of the footwear sole has molded parts which are adapted to the shape of the foot and are to have a shape on their upper sides which corresponds to the orthopedic requirements.
  • the upper and lower components are connected and blank blanks are punched out from such a composite strip in such a way that a composite construction is formed from the molded part adapted to the shape of the foot and a lower insole.
  • the punched edges on the molded part and the insole are generally right-angled, but can also have a slight deviation from the vertical in that the stamping process, which in itself almost only produces vertical molded parts, when the molded part is pressed together and the insole also produces an outer edge of the Permits molding at a cross-sectional angle of little more than 90 ° to the sole plane.
  • This patent application thus relates only a process for punching out sole blanks from a composite strip, it being expressly stipulated that the punching process for producing a shoe sole requires almost vertical molded parts, which expressly only have very slight deviations from e.g. B. less than 4 ° relative to the perpendicular to the sole level. In this respect, this patent application does not relate to: the formation of a lateral support of the feet within a sole of the foot or the edges of the footbed, but only a stamping process.
  • the aim of the present invention is to design it in such a way that, similar to the sole of the foot according to the older international patent application WO 87/07481 there is better support of the foot placed in the footbed, in particular with regard to horizontal forces, which become effective during walking in the plane or on slopes due to the dynamic loading of the footbed.
  • Both the vertical and horizontal forces acting on the side of the shaped foot sole should be absorbed in such a way that the pressure concentration on the outer edge areas of both the shaped foot sole and the outer outsole is reduced, thus increasing the durability of the shoe and serving the orthopedic purposes
  • the shape of the footbed is retained for longer.
  • a molded foot sole is to be created which, despite the inclined support, can be produced in the simplest possible form and in particular enables good lateral stabilization of the foot accommodated in the cup-shaped foot bed under static and dynamic loads.
  • the shaped foot sole or the outer outsole is provided on the side of the foot bed edges with an inclined support for absorbing forces that become horizontally effective, so that the side shells of the cup-shaped foot bed have an at least partially circumferentially formed support area, which in this respect laterally stabilizes the pointed and narrow foot bed edges.
  • the shaped foot sole is constructed in one layer, namely from a uniformly soft, elastic bedding material, in particular from a natural cork / rubber mixture.
  • the side shells of the cup-shaped footbed or its elastic bedding material and thus a foot which rests in the cup-shaped footbed on the side shells are formed by areas which are at least partially circumferentially formed on the side of the footbed outside the bowl-shaped footbed and which are essentially of the same material as that of the soft one , elastic footbed of the molded sole, supported.
  • the support of the side shells of the cup-shaped footbed or its elastic bedding material and thus the support of a foot in the cup-shaped footbed against the side shells is formed by areas which at least partially surround the side of the footbed edge outside the cup-shaped footbed, which in contrast to the "molded areas" of the first solution in the material are stronger than the elastic bedding material and are molded as such on the outer edge areas of the outsole or are formed by the edge areas of the outsole itself, these areas extending upward to the sole of the foot and at least partially enclosing it laterally.
  • the feet themselves are supported laterally above the tread surface in the cup-shaped footbed of the sole, a large proportion of the slope of the lateral support areas being located above the tread surface.
  • a large proportion of the slope of the lateral support areas being located above the tread surface.
  • the lateral support areas are designed with sloping or curved outer sides, i.e. the width of the lateral support increases towards the bottom surface or underside of the molded sole, there is an extremely functional inclined support for absorbing the dynamic horizontal forces acting from the side.
  • the pressure concentration on the outer edge areas of the outsole and the shaped foot sole is reduced to a fraction by the inclined support, which also results in increased durability.
  • the shaped foot sole Due to the inclined support of the shaped foot sole according to the invention or the foot bed edges which are now stabilized and drop steeply towards the inside of the foot bed, it is now possible to form the shaped foot sole from an extremely highly elastic, soft and light material.
  • the footbed in its form according to the invention can be formed from a highly elastic, soft plastic, for example a foamed material based on a polyolefin, an ethylene-co-vinyl acetate, a PVC, a natural rubber or a synthetic rubber or also polyurethane.
  • a highly elastic, soft plastic for example a foamed material based on a polyolefin, an ethylene-co-vinyl acetate, a PVC, a natural rubber or a synthetic rubber or also polyurethane.
  • the outer regions (4, 5) of the molded sole (1) formed on the side of the circumferential edge of the footbed (6) or on the side of the cup-shaped footbed (2) can be clearly seen. .
  • These areas (4, 5) are hatched for clarity. It is there Easily recognizable that in the footbed of a shaped sole with such external support of the side wall areas of the cup-shaped footbed (2) the foot is not only supported vertically, but also obliquely outwards.
  • the outer molded-on areas (4, 5) are designed with their outer side sloping downwards from the footbed edges (6) so that the shaped sole of the foot has an "inclined support" on its outer side.
  • the molded foot sole (1) thus has side shells (7, 8) which are supported obliquely outwards towards the floor by the beveled molded areas (4, 5).
  • the tread area for the foot was initially significantly larger all around the contour of the shoe than the bottom side of the shaped foot sole, or, according to a more recent embodiment, with the sidewalls of the shaped foot sole running vertically.
  • the inclined support results in a larger bottom side of the molded sole or a larger contact area of the outsole and the rest a much greater "bending resistance" of the side walls of the new shape of the sole of the molded foot with angled support compared to the old shape without such an inclined support.
  • FIG. 2 shows that in the case of an inclined floor, effective support of the foot in the side shells can only take place if the side shells themselves are supported outwards towards the floor by the outer molded and chamfered areas.
  • the shaped foot sole (1) shown in the drawings is made of a cork latex material with 90% by weight natural cork, the "latex portion” in particular resulting in a highly elastic, dimensionally stable, soft footbed in the shell-shaped footbed (2). Due to the use of the high natural cork content of 90%, the molded foot sole (1) is extremely light, with the latex content still ensuring that the natural cork material is held together securely. As the outer support fabric, the shaped foot sole (1) has a jute fabric (16) which is applied from the outside over the entire cork / latex shaped foot sole. (See Figure 6)
  • the size of the previous foot shape sole without lateral support of the foot bed edges according to the inner contour line is shown schematically in a plan view of the top or tread surface (9) of the foot shape sole, the outer contour line representing the course of the lateral inclined support (4, 5) clarifies.
  • This inclined support (4, 5) is coherent and begins in the front area of the shaped foot sole (1) at the shell shape (15) for the ball area of the foot and then runs to the rear area of the shaped foot sole around the shell shape (14) of the heel area.
  • On the back of the shell shape (14) of the heel part is the sloping support of constant width (approx.
  • the edge of the footbed (6) is approximately 3 cm and in the area of the shell shape (14) of the heel part is approximately 1.5 cm.
  • FIG. 7 shows the significantly lower "bending strength" of the side walls of the side shells (7, 8) in the case of vertically running side walls according to the previous embodiment of the shaped foot sole with the same size foot side and bottom side compared to the "bending strength" of the shaped foot sole with angled support.
  • the curve profile shown in FIGS. 4 and 5 corresponds approximately to the pressure profile up to the outer side edge of the outsoles with and without inclined support. It can be clearly seen that, according to FIG. 5, the pressure concentration on the outermost edges of the outsoles is considerably reduced compared to the extremely high pressure concentration according to FIG. 4 (vertical support) in the case of the inclined support according to the invention when lateral loads occur.
  • the inclined support By means of the inclined support, these compressive forces are dissipated inward in front of the outermost edges, the pressure occurring due to the horizontal forces being distributed over a large area of the outsole to the inside.
  • the inclined support thus reduces the pressure concentration to a fraction and the pressure load is largely distributed over the side areas inwards over the outsole, which increases the durability of the outsole and the molded sole.
  • a significant further advantage of a molded foot sole with angled support is that, despite the support function to be achieved by the foot bedding, the molded foot sole can be produced from a highly elastic and soft material and thus not only appears light, but also extremely comfortable on the feet during the walk.
  • a highly elastic and soft material has so far not been used in the case of molded soles with obliquely inwardly drawn support or vertical support of the surrounding outer footbed edges, because otherwise the side shells will bend considerably in this case when the side pressure is applied.
  • the molded foot sole can be made from a wide variety of materials, e.g. B. cork-latex mixtures, natural cork, thermo-cork or polyurethane foam.
  • B. cork-latex mixtures natural cork, thermo-cork or polyurethane foam.
  • the combination of a cork-leather sole with soft foam pads or foam pads can also be done.
  • the shaped sole of the foot and the outsole can be molded in one piece in a particularly functional manner, an EVA material according to claim 15 or a high-quality polyurethane material preferably being used.
  • molded sole with a circumferential, molded in one piece with the molded sole Inclined support consists in the significantly increased fatigue strength of the molded sole.
  • Such shaped foot soles can also be used as such for rubber boots, military shoes and hiking boots.
  • the regions (4, 5) which are integrally formed on the side and serve to support the foot bed (2) at an angle can of course be designed in a wide variety of designs. For example, they can be divided into individual, spaced-apart areas which are arranged on the outside around the foot bed (2) or the edge of the foot bed.
  • the lateral inclined support of the shaped foot sole is formed by areas (27, 28) surrounding the shaped foot sole (24) on the outer wall (31) thereof. These outer regions which are non-positively connected to the outer wall (31) of the molded sole (24) are directly molded onto the outer edge regions of the outsole (25). (see Fig. 8)
  • the outer outsole (25) is produced with the molded-on, outer areas (27, 28) forming an inclined support as a one-piece, coherent workpiece in the press mold.
  • the same material can be used to form the outer lateral areas (27, 28) as for the outsole, which has extremely high abrasion resistance. Because of the flexural strength and the elasticity of the outsole material that is present within certain limits, an optimal lateral support of the side shells of the cup-shaped footbed (26) is achieved.
  • the lateral outer molded-on areas (27, 28) of the outsole (25) project with their upwardly tapering end section over the circumferential outer footbed edge (29) of the cup-shaped footbed (26). In this way it is possible to additionally stabilize the shaped sole of the foot in the upper region of the cup-shaped footbed at the outer edge of the footbed (29) surrounding it.
  • the outer sole (25), which is designed as a one-piece workpiece, and the outer regions (27, 28) molded onto it are connected to the shaped sole (24) by gluing with an adhesive, such as is used to connect an outsole (3) to the shaped sole (1) or generally used to connect such shoe parts.
  • a closed-cell, foamed plastic material based on a polyolefin is used as the material of the molded foot sole (24), the material of the outer outsole and the regions (27, 28) molded onto it on the outside likewise consisting of such a plastic material which compresses after foaming is to obtain the desired bending stiffness and abrasion resistance.
  • a jute fabric is applied to the surface of these parts, as with the molded foot sole (1).
  • the outer areas (27, 28) surrounding the entire heel area in the area behind the ball area have outer side walls which slope straight down to the level of the outsole (25) so that the molded areas (27, 28) in form right-angled triangles on a cross-sectional plane perpendicular to the outsole.
  • the composite construction itself can be formed as a one-piece workpiece in that the bottom of the molded foot sole simultaneously with its manufacture to the outside Outsole (25) is cast with the lateral areas (27, 28) serving for inclined support. In this way you get an optimal connection between these plastic parts. In the right part of FIG. 8, this uniform transition is indicated by dashed lines at the interfaces between the shaped foot sole (24) or the regions (27, 28) serving for inclined support and the outsole (25).
  • the shaped foot sole (24) according to FIG. 8 as well as the shaped foot sole (1) according to FIG. 1 have, as indicated in FIG. 6, on the rear side shown there, that is to say the bottom side (10), of longitudinal depressions (32, 33 ) on. These open to the outer side walls (12, 13) of the molded sole (1,24) and below this to the bottom side (10, 30). Since the front upper leather end sections engage in these longitudinal depressions (32, 33) to form a sandal that has the sole of the foot, the longitudinal depressions are created in the area between the toe and ball area of the foot. Since the longitudinal depressions (32, 33) are shown hidden in FIG. 6 by the tread surface (9) of the molded sole (1), these are indicated by dashed lines.
