Abstract

The invention relates to an inner sole (11) for a shoe, comprising a base body (36), a covering layer (37) and several cushioned layers (12, 13, 14) arranged on the surface of the sole. A first cushioned layer (12) is provided in the ball area of the forefoot, a second cushioned layer (13) is included in the transition area of the metatarsus and the tarsus and a third cushioned area is provided between the metatarsus and the heel. The cushioned layers (12-16) are subdivided into individual, separate plateau-like fields (18-27) which are located close to each other in the transversal direction of the sole surface. This provides an inner sole which brings about a substantial improvement in the transport of fluids in the venous and lymphatic vessel system in the legs during movement of the foot joints and ankle joints by means of synergistic support of the muscle structure.

Description

The present invention relates to a footbed trained shoe insole according to the preamble of Claim 1 or that of claim 4.

On average every fifth person in the age group between 20 and and 70 years is because of a venous disease in need of treatment and even one in three has pathological ones Vein changes that are not yet invasive are in need of treatment, but still complaints cause and may need treatment. This generally stems from an often hereditary condition Connective tissue weakness resulting in a relaxation of the Vein walls and thus inability to close  the venous valve leads. This leads to a reduction of venous backflow from the legs into the body.

Supporting measures are through so-called Support stockings known, preventive measures in particular in the case of people who predominantly have a job Do not perform sedentary or standing work. Here it is only recommended to close the legs as much as possible move the venous backflow out of your legs increase towards the body by the fact that the so-called foot and Calf muscle pump is promoted. This is through Frequent barefoot walking is largely supported, however with footwear commonly used today is adversely affected.

Running shoes are known in the heel area elastic layers in the form of inserts can be used. However, these known elastic layers are intended only the specific one that occurs when running Compensate for overload or at least partially help avoid (DE 39 02 872 A1).

In a shoe insole known from DE 87 00 681 U1 the pillow-like layers are also considered over the top Elevated ridges formed and sole covering layer in one piece in the respective joint areas of the foot  provided over a large area. This does not allow an optimal one Support the individual areas of the foot.

The object of the present invention is therefore a To create shoe insole of the type mentioned, the through synergistic support of the movement of the foot and Hocks a significant improvement in venous Backflow through the legs into the body allows.

To solve this problem, one is a footbed trained shoe insole of the type mentioned in Claim 1 or the features specified in claim 4 intended.

By the measures according to the invention, according to which pillow-like layers in certain foot areas and are specifically divided into separate fields, is due to the sinking of the foot in the sink areas optimal support is achieved. This results in a synergy in the movement of the individual joints that as a continuous homogeneous wave of movement a positive one Influence on the contractions of the muscles of the lower upper ankle and calf muscles Has. There is also a promotion of the so-called foot and Calf muscle pump, causing an increase in venous Backflow from the legs leads to the body.  

According to further refinements according to the characteristics of the Claim 2 and / or 3 or 5 and / or 6 are in further essential areas provided pillow-like layers.

Alternative configurations result from the features of claim 7 or claim 8. According to the latter embodiment leads the Interlayer to another relatively elastic Support the foot. It is useful that Provide features according to claim 9 or 10.

Further advantageous configurations result from the Features of one or more of claims 11 to 15.

According to the features of claim 16 or 17, the Shoe insole either individually as an insole usable or integrated directly into a shoe Sole provided.

The shoe insole 11 or 111 or 111 'shown in the drawing and designed as a footbed according to two exemplary embodiments and a variant of the second exemplary embodiment of the present invention serves to synergistically support the movement of the ankles and ankles to improve the venous backflow through the legs in the Body and can be designed as an insole or as a sole integrated into a shoe.

As can be seen from FIGS. 1 and 6, the insole 11 and 111 has a plurality of cushion-like layers 12 to 16 and 112 to 116 provided over the sole surface 17 and 117 , of which the cushion-like layers 12 , 112 , 13 , 113 and 14 , 114 are divided into separate fields 18 to 22 , 118 to 122 , and 23 to 25 , 123 to 125 and 26 , 27 , 126 , 127, respectively.

The first pillow-like layer 12 , 112 is provided in the area of the forefoot joint, ie in the area of the toes. This first pillow-like layer 12 , 112 is subdivided into the five fields 18 to 22 , 118 to 122 , which are separated from one another and arranged next to one another in the transverse direction of the insole 11 , 111 . The individual fields 18 to 22 , 118 to 122 are of different widths and lengths, corresponding approximately to the base area of the partial areas of the respective individual toes. The same applies to the shape of the front and rear boundary lines 28 , 128 and 29 , 129 of this first pillow-like layer 12 , 112 . The second pillow-like layer 13 , 113 is provided in the transition area between the metatarsus and the foot root and in an area which faces away from the arch of the foot. This second pillow-like layer 13 , 113 is divided into the three fields 23 to 25 , 123 to 125 , which are shaped in accordance with this partial region of the metatarsus / foot root and are arranged lying next to one another in the transverse direction of the insole 11 , 111 . The same applies to the shape of the peripheral boundary line 31 , 131 of this second pillow-like layer 13 , 113 . The third pillow-like layer 14 , 114 is provided in a transition area from the metatarsus and the heel and is divided into the two fields 26 , 126 and 27 , 127 , which, viewed in the transverse direction of the insole 11 , 111 , lie next to one another and are provided on the outside on the side. Here too, the circumferential boundary line 32 , 132 corresponds approximately to the transition area from the midfoot to the heel.

The fourth pillow-like layer 15 or 115 is arranged in the area of the heel and is designed as a uniform, undivided layer which is approximately oval in the transverse or longitudinal direction of the insole 11 , 111 . The fifth pillow-like layer 16 , 116 is likewise designed as a uniform, non-subdivided layer, but is provided in the region of the arch of the foot in an approximately crescent shape.

The pillow-like layers 12 to 16 , 112 to 116 are made of an elastic (foam) material, for example a silicone. They have a flat upper surface and are approximately rectangular in cross section, advantageously slightly trapezoidal.

In the first exemplary embodiment according to FIGS. 1 to 3, the insole 11 has a three-layer sole base body 36 , which forms the basic shape of the insole 11 and, according to FIG. 1, is designed according to one foot, here the right foot. It goes without saying that the correspondingly different, ie left-hand insole 11 is mirror-symmetrical. The sole base body 36 consists, for example, of three cork layers 33 , 34 , 35 . A sole cover layer 37 , which is made of leather, for example, is provided on the sole base body 36 . The cushion-like layers 12 to 16 are arranged between the sole base body 36 and the sole cover layer 37 in a manner embedded in the sole base body 36 . For this purpose, the sole base body 36 is provided in its upper and middle layers 33 , 34 with corresponding depressions 38 which have a different base area corresponding to the fields 18 to 27 of the pillow-like layers 12 to 14 and corresponding to the pillow-like layers 15 , 16 . The depressions 38 are worked into the sole base body 36 so deeply that the upper side of the cushion-like layers 12 to 16 lies approximately in one plane with the surface of the sole base body 36 . In this exemplary embodiment, the depressions 38 extend to the top of the lower layer 35 . The pillow-like layers 12 to 16 each have 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 the sole cover layer 37 covers the cushion-like layers 12 to 16 in such a way that they or their fields 18 to 27 are recessed around the edges and are firmly connected, preferably glued, to the middle layer 34 of the sole base body 36 , so that there are no boundary lines 28 , 29 and 31 , 32 result in intermediate boundary lines 41 to 47 running approximately perpendicular to the transverse direction of the insole 11 . In other words, the depressions 38 are formed corresponding to the total base area of the pillow-like layers 12 to 16 .

In the two variants of this, as shown in FIGS. 4 and 5 is given 12 to 16 of the shoe inner sole 11, including the arrangement of the fields 18 to 27 as well as in Fig. 1, the upper surface arrangement of the pillow-like layers. The main difference in the variants of FIGS. 4 and 5 compared to the exemplary embodiment in FIGS . 2 and 3 is that between the sole base body 36 'or 36 ''and the sole cover layer 37 ' or 37 '' there is a cushion-like elastic intermediate layer 51 'or 51 ''is provided over the entire surface of the sole base body 36 '. The intermediate layer 51 is made of the same elastic material as the pillow-like layers 12 to 16 and with the entire surface of one of the layers 34 '( FIG. 4) or 35 ''( FIG. 5) of the sole base body 36 ' which have no depressions. firmly connected, preferably glued.

According to FIG. 5, the cushion-like intermediate layer 51 ″ has an approximately uniform thickness over the entire base area in the range of 2 to 3 mm, so that a continuous, flat cushion is obtained which is considerably more elastic than the layers of the sole base body 36 ′. In this variant, starting from FIG. 3, the intermediate layer 51 ″ is only placed over the entire area between the lower layer 35 ′ and the middle layer 34 ″.

FIG. 4 is the intermediate layer 51 'between the middle layer 34' and the upper layer 33 'and has a different thickness. Thus here the upper layer 33 'is provided with depressions 38 ' and the cushion-like intermediate layer 51 'is provided with depressions 52 corresponding to the depressions 38 for receiving the cushion-like layers 12 to 16 , via which the upper material or the sole cover layer 37 ' in turn is in the same Way as the sole cover layer 37 extends according to FIGS . 2 and 3.

In the second exemplary embodiment according to FIGS. 6 to 10, the insole 111 has a two-layer sole base 136 , which forms the basic shape of the insole 111 and, according to FIGS. 6 and 9, is designed according to one foot, here the left foot. It also goes without saying here that the correspondingly different one, ie the right inner sole, is mirror-symmetrical. The sole base body 136 is composed of two cork layers, for example. A sole cover layer 137 , which is made of leather, for example, is provided on the sole base body 136 .

The cushion-like layers 112 to 116 are arranged between the sole base body 136 and the sole cover layer 137 in a manner embedded in the sole base body 136 . For this purpose, the sole base body 136 is provided with corresponding depressions 138 , which have a different base area corresponding to the fields 118 to 127 of the pillow-like layers 112 to 114 and corresponding to the pillow-like layer 115 . FIGS. 9 and 10 show in plan view and in section the respective cavities 138th The sole base body 136 thus has a maximum thickness in the range from 3.5 to 4 mm, preferably from 3.7 mm and a minimum thickness in the region of its depressions 138 between approximately 1 mm and 1.5 mm, preferably from 1.3 mm. In Fig. 9 is indicated also that the example. Multilayered sole base body 153 is coated on its upper surface 136 over the entire surface of a fine textile overlay 139th In a manner not shown, the underside 154 of the sole base body 136 can instead or additionally be covered with such a fine textile covering 139 over the entire surface. The sole base body 136 or its layers are made from cork scrap pressed with a binder.

According to FIG. 7, the upper side 153 of the sole base body 136 is also covered over the entire surface with an elastic or pillow-like intermediate layer 151 . The intermediate layer 151 thus covers the entire surface including the depressions 138 of the sole base body 136 , so that depressions 152 corresponding to the depressions 138 are retained in the intermediate layer 151 . The intermediate layer 151 has a continuous thickness of approximately 3 mm, for example. The intermediate layer 151 , like the pillow-like layers 112 to 116, is preferably made of a foam, for example foamed natural latex.

In the recesses 152 of the intermediate layer 151 , the pillow-like layers 112 to 115 are inserted, which, for example, are made of the foamed natural latex mentioned and which, for example, have a thickness in the range between 4 and 5 mm, preferably 4.5 mm. In contrast, the pillow-like layer 116 is not arranged in a depression but directly on the intermediate layer 151 which is flat in this area, ie provided without a depression. This pillow-like layer 116 is also about 4 to 5 mm, preferably 4.5 mm thick at its thickest point, with its thickness steadily decreasing towards the inside of the sole III. The upper sides 156 of the pillow-like layers 112 to 115 are thus raised from the upper side 157 of the intermediate layer 151 by 1.5 to 2.5 mm, preferably by about 2 mm. The upper material or the sole cover layer 137 covers the pillow-like layer 116 and also the pillow-like layers 112 to 115 in such a way that the latter or their fields 118 to 127 surround recessed edges and are firmly connected, preferably glued, to the intermediate layer 151 , so that In addition to the boundary lines 128 , 129 and 131 , 132 , intermediate boundary lines or regions 141 to 147 extending approximately perpendicular to the transverse direction of the insole 111 result.

The variant shown in FIGS. 11 and 12 differs from the second exemplary embodiment only in the configuration of the second pillow-like layer 113 '. FIGS. 11 and 12 for this variant the same reference numerals as Figs. 6 to 10, wherein only one line is added.

Referring to FIGS. 11 and 12, the second cushioned layer 113 'with the outer box 125', the intermediate field 124 'is provided and the inner field 123', the first two corresponding to the representations of FIGS. 6 and 7 are formed. The inner field 123 'of the second pillow-like layer 113 ' is arcuate in relation to the field 123 according to FIG. 6 towards the first pillow-like layer 112 '. This arcuate region 123 'extends and widens the front surface of the field 123 '. As can be seen in FIG. 12, this arched region 123 'is not exactly the same as the other surface regions of the cushion-like layer 113 ', but is curved upwards, that is to say it is again raised compared to the raised top of the sole cover layer 137 '. This curvature raises the level of the arcuate region 123 'compared to the rest of the field 123 ' and the fields 124 'and 125 ' by about 2 mm. This arch-shaped, upward-arched area 123 ″ results in a well-being point in the context of the foot reflex zones, which has a particularly advantageous effect for people in standing jobs.
