Description

INTERNAL TEMPLATE FOR A SHOE DESCRIPTION OF THE INVENTION The present invention relates to an internal insole for a shoe, which is presented as a foot support, according to the preamble of claim 1, or respectively claim 4. On average, one in five people in the group aged between 20 and 70 years needs treatment due to diseased veins, particularly one in three people suffer pathological changes in the veins, which, although they do not need invasive treatment yet, cause problems that may need future treatment. In general, the cause of this is often a genetically induced weakness of the connective tissues, which leads to a relaxation of the vein walls, and therefore a lack in the ability of the venous valves to close. This results in a reduction of venous return flow from the legs to the body. The support measures are known in the form of the so-called pressure hose, although preventive measures are not known, in particular in relation to persons who, due to their occupation, perform predominantly sitting or standing tasks. In these cases, it is suggested to move the legs as much as possible in order to increase the flow of venous return from the legs to the body promoting the so-called foot and calf muscle pumping. This is helped to a large extent by walking with the bare foot, although the shoes that are accustomed these days "have a rather disadvantageous effect.The walking shoes are known, where the elastic layers in the support form are used. In the area of the heel, although these known elastic layers are intended only to compensate for the specific overloads that occur during the walk, or at least to help partially prevent them (DE 39 02 872 Al) .In relation to an internal orthopedic insole for shoes known from DE 87 00 681 Ul, the cushion-like layers are also presented as an arched cushion, which projects upwards over the cover layer of the insoles, and is provided in one piece with a large surface to support and distribute the pressure in defined areas of the foot An internal jig for a shoe is also known from the DE 35 08 582 C2, which has a cushion elastic band in the area of the reflex areas of the foot. This cushion has an arcuate or symmetrically or asymmetrically warped shape, and is essentially circular in a view from above, and is therefore used to stimulate the nerves in that reflex zone. The reflex zones of the foot have an exclusive effect on the nervous system, which, among others, affects the arterial blood supply of the defined organs. No remedy can be achieved by this for the problems of the venous blood flow mentioned at the beginning, particularly in the lower area of the leg. Therefore, the object of the present invention is to create an internal insole for a shoe of the type mentioned at the beginning, which makes possible a considerable improvement of venous return flow through the legs towards the body, starting at the foot, means of the synergistic support of the muscular contraction in the course of the movement of the foot and the joints of the ankle.

To obtain this object, the features cited in claim 1, or respective claim 4, are provided in connection with an internal insole for a shoe of the aforementioned type. Suitable support areas, which positively affect a contraction of the foot muscle, result from the steps according to the invention, where the layers as pads are not raised separately, but are placed in a high plateau-like shape in defined areas of the foot. foot and are divided into fields that are separated from each other. These discrete support points are arranged in such a way that muscle contraction is indicated, or respectively stimulated and therefore improved during the normal movement of the foot, although considerably also while standing. This results in a synergistic support during the movement sequence of the individual joints which, as a wave of homogeneous continuous movement, has a positive effect on the venous system and lymphatic vessels. In other words, a homogenous mechanical compression of the venous system and lymphatic vessels takes place, which leads to an increase in the venous return flow from the legs towards the body. This characteristic support movement promotes the action of so-called foot and calf muscle pumping, in particular since the division of the cushion-like layers into individual areas is similar to the arrangement of the muscles in the foot. With additional embodiments according to the features of claim 2, and / or 3 and / or 5 and / or 6, the acoamike-like layers are provided in additional important areas of muscular disposition. The alternative embodiments are the result of the features of claim 7, or respectively claim 8. It is practical here to provide the features according to claims 9 or 10. The additional advantageous embodiments result from the characteristics of one or several of claims 11 to 15. According to the features of claims 16 or 17, the internal jig for a shoe can be used individually as a jig, or. It is provided as a template that is directly integrated into a shoe. Further details of the invention can be taken from the following description, in which the illustrative embodiments represented in the drawings are described in detail and explained. They are shown in: Figure 1 is a top view of an internal shoe insole according to the first illustrative embodiment of the present invention, Figure 2 is a section along the line II-II in FIG. Figure 2 in an enlarged view, Figure 3 is a section along the line III-III in Figure 1 in an elongated view, and Figures 4 and 5, respectively, are a section similar to section in Figure 3, but according to two variants of the first illustrative embodiment, Figure 6 is a top view on an internal jig of a shoe according to a second illustrative embodiment of the present invention, Figure 7 is a longitudinal section similar to the section of Figure 3, although through the second illustrative embodiment, Figure 8 is an interior view in the longitudinal direction of the second illustrative embodiment, Figure 9 is a top view on the pre-processing step. saw from the internal insole of the shoe according to the second illustrative embodiment of the present invention, Figure 10 is a longitudinal sectional view similar to that of Figure 7, but in the longitudinal direction of Figure 9, Figure 11 is a top view of an internal insole of a shoe according to a variant of the second illustrative embodiment of the invention, and Figure 12, is a longitudinal similar to the section of Figures 7, but through the variation of the second illustrative modality. The internal template 11, or respectively 111, or respectively 111 'represented in the drawings and presented as a foot support, for example in accordance with two illustrative embodiments and a variant of the second illustrative embodiment of the present invention, is used for the synergistic support of the musculature in the course of the movement of the foot and ankle joints to improve the transport of fluids in the venous system and of lymphatic vessels through the legs, and can be presented as a template or as a template integrated into a shoe. As can be seen from Figures 1 and 6, the internal template 11 or respectively 111, has several layers similar to cushions 12 to 16, respectively 112 to 116, provided on the template surface 17 or respectively 117, of which the cushion-like layers 12, 112, 13, 113 and 14, 114 are divided into fields similar to separate plates 18 to 22, 118 to 122, or respectively 23 to 25, or respectively 123 to 125, or respectively 26, 27 , 126, 127, which are separated one from the other. The first cushion-like layer 12, 112 is provided in the articulation area of the forefoot, that is, in the area of the toes. This first cushion-like layer 12, 112 is divided into five fields 18 to 22, 118 to 122, which are separated from one another and placed close to each other in the transverse direction of the internal template 11, 111. The individual fields 18 22 to 118 to 122 are of different width and length, approximately corresponding to the base area of the partial areas of the respective individual fingers. This is correspondingly true for the shape of the front and rear edge line 28, 128 or 29, 129 respectively of this first cushion-like first layer 12, 112. The second cushion-like second layer 13, 113 is provided in the transition area. between the metatarsal and the tarsus and in the area that faces outwards from the arch of the plant. This second cushion-like layer 13, 113 is divided into three fields 23 to 25, 123 to 125, which are formed to correspond to this partial area of the tar tab and are placed divided and extending close to each other, in the transverse direction of the internal template 11, 111. This is correspondingly true for the circumferential edge line 31, 131 of this second cushion-like layer 13, 113. The third cushion-like layer 14, 114 is provided in a transition area between the metatarsal and the heel and divided into two fields 26, 126 and 27, 127, which seen in the transverse direction of the internal jig 11, 111, is located close to one another and is provided laterally on the outside. Here also, the circumferential edge line 32, 132 corresponds approximately to the transition area between the metatarsal and the heel. The fourth cushion-like layer 15, or 115 respectively, is positioned in the heel area and is designated in a plate-like shape as a uniform undivided layer, which is approximately oval in the transverse or longitudinal direction of the insole internal 11, 111. The fifth cushion-like layer 16, 116 is also presented as a uniform undivided layer, but is provided in the approximate shape of a sickle in the area of the plantar arch. The cushion-like layers 12 to 16, 112 to 116 are made of an elastic material (foam), for example, of silicon. They have a flat upper surface and are presented to be approximately rectangular, advantageously slightly trapezoidal, in cross section. In the first illustrative embodiment according to Figures 1 to 3, the inner layer 11 has a template base body 36, which here is three-layer, constitutes the basic shape of the internal template 11 and according to the Figure 1 is designed to correspond to a foot, here on the right foot. It is understood that the other corresponding, that is, the left internal template 11, is designed to be symmetrically mirror image. The template base body 36 consists, for example, of three layers of cork 33, 34, 35. A template cover layer 37, which for example is made of leather, is provided with the base body of the insole 36. The cushion-like layers 12 to 16 are placed in the base body of the insole 36 in a recessed form between the base body of the insole 36 and the insole cover layer 37. The upper and middle layers 33, 34 of the template base body 36 are provided with corresponding depressions 38 for this purpose which, corresponding to fields 18 to 27 of the similar cushioning layers 12 to 14, and which correspond to the cushion-like layers 15, 16 have different base surfaces. The depressions 38 have been worked in the base body of the jig 38 to a depth such that the respective flat top plate-like portion of the cushion-like layers 12 to 15 is located approximately in a plane, ie coplanar with the surface of the base body of template 36. The cover similar to cushion 16 constitutes an exception. With this illustrative embodiment, the depressions 38 extend as far as the upper part of the lower layer 35. Among themselves, the similar cushioning layers 12 to 15 are of approximately the same height and are in a range between 2 to 5 mm , preferably in a range of 3 mm. The upper material, or respectively, the template cover layer 37, covers the cushion-like layers 12 to 16 in such a way that they or their respective fields 18 to 27 are enclosed by a depression along the edge and are preferably fixedly connected with glue to the central layer 34 of the template base body 36, so that in addition to the edge lines 28, 29 and 31, 32, the intermediate edge lines 41 to 47 result which they extend approximately vertically with respect to the transverse direction of the internal jig 11. In other words, the depressions 38 are designated to correspond to the total base surface of the cushion-like layers 12 to 15.

With the two variants according to Figures 4 and 5, the surface arrangement of the cushion-like layers 12 to 15 of the internal jig 11 of the shoe, including the arrangement of the fields 18 to 27, is exactly the same as that shown in FIG. shown in Figure 1. The essential difference of the variants in Figures 4 and 5 with respect to the illustrative embodiment of Figures 2 and 3 is located in that the cushion-like elastic intermediate layer 51 'or respectively 51"is provided. on the surface of the base body of the jig 36 'between the stencil base body 36', or respectively 36", and the stencil cover layer 37 'or respective layer 37". Here, the intermediate layer 51 is made of the same elastic material as the similar layers aacomposed to 12 to 16, and is fixedly connected to, preferably glued to, the entire surface of one of the layers 34 '(FIG. 4), or respectively 35 '' (Figure 5), which have no depressions, of the template base body 36 '. According to Figure 5, the cushion-like intermediate layer 51"is of a thickness in the range of 2 to 3 mm, which is approximately uniform over the entire base surface, so that a continuous flat cushion results, the which is considerably more elastic than the layers of the template base body 36 '. Compared to Figure 3, in this variant of the intermediate layer 51"has been placed over the entire surface between the lower layer 35 'and the central layer 34". According to Figure 4, the intermediate layer 51 'is located between the central layer 34' and the upper layer 33 'and has a different thickness. Accordingly, the upper layer 33 'here is provided with depressions 38' and the cushion-like intermediate layer 51 with depressions 52 corresponding to the depressions 38 for receiving the cushion-like layers 12 to 16, on which the upper material, or respectively the template cover layer 37 'extends again in the same manner as the template cover layer 37 according to Figures 2 and 3. With the second illustrative embodiment according to Figures 6 to 10, the Internal template 111 has a double layer template base body 136, which constitutes the basic form of internal template 111 and which according to Figure 6, or 9, is designed to correspond. to one foot, here the left foot. It is also understood that the corresponding other, that is, the right internal template, is designed to be mirror image symmetrically. The template base body 136 is constructed from two layers of cork, for example. A template cover layer 137 is provided on the template base body, which is made, for example, of skin. Layers similar to shelter 112 a 115 are placed between the template base body 136 and the template cover layer 137 in a recessed manner. The template base body 36 is provided with corresponding depressions 138 for this purpose, which correspond to the fields 118 to 127 of the cushion-like layers 112 to 114 and which correspond to the cushion-like layer 115, have a surface of different base. Figures 9 and 10 show the corresponding depressions 138 in a top view, or respectively in section. - Therefore, the template base body 136 has a maximum thickness in the range of between 3.5 to 4 mm, preferably of 3.7 mm and a minimum thickness in the area of its depressions 138 between approximately 1 mm and 1.5 mm , preferably 1.3 mm. It is further indicated in Figure 9 that the entire surface 136 of the template base body 153, which for example is multi-layer, is covered with a thin textile cover 139. It is possible in a non-shown form that, instead of or in addition to this, the underside 154 of the stencil base body 136 can be covered over its entire length with such a thin textile covering. The basic body of template 136or, respectively, their layers, are made of compacted cork compacted by means of a binder. According to Figure 7, the entire surface 153 of the stencil base body 136 is further covered with an intermediate layer similar to respective or elastic cushion 151. The intermediate layer 151 thus covers the entire surface, including the depressions 138 of the stencil base body 136 so that depressions 152 corresponding to depressions 138 remain in intermediate layer 151. Intermediate layer 151 has a continuous thickness of, for example, about 3 mm. As with the similar cushion layers 112 to 11β, the intermediate layer 151 is preferably made of a foamed material, for example natural and foamed latex. The cushion-like layers 112 to 115 have been placed in the depressions 152 of the intermediate layer 151 and consist, for example, of the foamed natural latex and have a thickness in the range between 4 and 5 mm, preferably 4.5 mm for example. In comparison to this, the cushion-like layer 116 for the foot arch is not placed in a depression but directly on an intermediate layer 151, which in this area is flat, that is, it is not provided with depressions. On its thickest part, this cushion-like layer 116 also has a thickness of approximately 4 to 5 mm, preferably 4.5 mm, where its thickness decreases continuously towards the interior of the template 111. Therefore, the flat surfaces 156 of the similar cushion-like layers 112 to 115 are raised by 1.5 to 2.5 mm, preferably approximately 2 mm, on the surface 157 of the intermediate layer 151. The material on the upper part or the cover layer the template 137 covers the cushion-like layer 116 and in addition the cushion-like layers 112 to 115 in such a way that the latter, or respectively its fields 118 to 127, are enclosed by a depression along the edge and are firmly connected with, preferably glued to, the intermediate layer 151 so that, in addition to the edge lines 128, 129 and 131, 132, the edge lines, intermediate or the respective areas 1 41 to 147, they result, which extend approximately vertically with respect to the transverse direction of the internal template 111. The variant shown in Figures 11 and 12 differs from the second illustrative embodiment only in the design of the second similar layer. to cushion 113 '. Figures 11 and 12 for this variant have the same reference numbers as those in Figures 6 to 10, only that the premium apostrophe has been added. According to Figures 11 and 12, the second cushion-like layer 113 'is provided with the external field 125', the central field 124 'and the internal field 123' where the former are designed in accordance with the representations in Figures 6 and 7. Compared with the field 123 in Figure 6, the inner field 123 'of the second cushion-like layer 113' has been pulled towards, forward in an arched form towards the first layer similar to cushioning 112 '. This arc-shaped extended area 123 'elongates and widens the frontal area of the field 123'. As can be seen in Figure 12, this arc-shaped extended area 123 'is not level with the remaining surface areas of the cushion-like layer 113' but is arched upwards, ie raised back to the relation to the raised surface of the cover layer of the template 137 '. This arch raises the level of the arc-shaped extended area 123 'relative to the remaining area of the field 123' and the fields 124 'and 125' by approximately 2 mm.
