Abstract

Sole chassis for shoes consisting of one, the forefoot area associated flexible front sheet, which is hingedly connected via a bending edge with a Hinterfußbereich associated, rigid rear leaf, wherein the front sheet of a corrugated structural sole made of spring steel or other flexible, hard material, the angle bendable to the longitudinal axis and formed rigid in the transverse region and is connected via a bending edge with the backsheet.

Description

The invention relates to a sole chassis for shoes according to the preamble of claim 1.

Sole chassis for shoes are used as a basic design for building a shoe, wherein the shoe upper is connected via known connecting means (gluing, stitching, pinching) with the sole chassis. A shoe construction of a welted shoe, for example, is that an insole is reinforced with a hinge spring as a joint piece and in the rear foot with a paragraph z. B. connected via nails or a bond. The underside of the insole is covered with an outsole. Between the insole and the outsole a ball mass is arranged.

The connection between the shoe upper and the insole takes place in a welted shoe by a double seam, which connects the two parts circumferentially.

Such a known shoe structure is characterized in that the rear foot region of the insole (back sheet) is formed rigid, because z. B. in this area, a hinge spring is arranged, which connects the rear portion rigidly with the paragraph, while the front portion (front sheet) is designed to be flexible in order to allow a kinking of the forefoot and a pronation movement during walking.

Such a shoe structure has proven itself on a large scale and it was with the going back to the same inventor DE 10 2008 059 030 A1 recognized that improved support of the foot can be achieved by using an insole which is inserted into a previously mentioned shoe structure

The cited document discloses an insole which is integrally formed from spring steel, and which can be used in shoes as a separately insertable support sole. Characteristic of this known insole is the use of spring steel or other flexurally elastic material, which equips the insole with a sufficient transverse stability and superior longitudinal flexibility.

It has now been found that an insole extending over the entire length of the foot is unfavorable in a shoe structure of the type mentioned at the beginning, because the actual supporting force is only achieved if - in particular for sports shoes - the entire sole surface is wedge-shaped, d , H. without offset or a self-contained outsole is given.

The use of an insole in a previously mentioned shoe structure according to the subject matter of DE 10 2008 059 030 A1 has the further disadvantage that the shoe construction is thus unfavorably increased and also higher production costs arise because on the previously described, known shoe structure consisting of an insole and a cover of the insole still in addition the insole made of spring steel or other flexible material must be inserted.

The invention is therefore based on the object to form a sole chassis for shoes of the type mentioned so that at low height excellent stability and good longitudinal stability of the sole chassis is also given paragraph-wearing shoes or in such shoes in which a blast is present ,

To solve the problem, the invention is characterized by the technical teaching of claim 1.

An essential feature of the invention is that the sole chassis according to the invention no longer consists of a two-part insole, which is rigid in the rear foot and flexible in the front area. Instead, the invention proposes to form the front leaf of the known sole chassis as a corrugated structural sole made of spring steel or another flexible material and to connect via a bending edge with the rigid rear leaf.

Thus, a completely new type of sole chassis is created, because instead of training an insole as a sole chassis, a two-part sole chassis consisting of a front sheet forming corrugated structural sole is now proposed, which is connected via a bending edge hinged to the rear foot area forming, rigid rear leaf.

Thus, the shoe structure is significantly reduced, because it is no longer the use of an additional insole for the subject of DE 10 2008 059 030 A1 necessary because according to the invention, the insole described there according to the invention is now part of a sole chassis.

This significantly reduces the standing height, so that the human foot is supported more tightly over the footprint, which is particularly important in various sports or when walking. Furthermore, it is essential that by the formation of an at least two-part soleplate, whose front leaf is formed as a wavy structural sole, now superior wearing properties can be achieved. By replacing the conventional insole through the corrugated structural sole according to the invention, the foot is given a previously unknown stability from below with simultaneous mobility. The sole chassis according to the invention provides a stable base for the state and the course. It is achieved greater stability, due to the transverse stability of the corrugated structural sole according to the invention, which supports the bale area of the human foot especially in the ball area by applying an upward support force, so that sagging or crushing the Fußhohlgewölbes down in the ball area is avoided. The clinical picture of hallux valgus (crooked toe) is successfully controlled with the sole of the invention.

In this clinical appearance, the bone beam, which connects the metatarsus with the big toe, spreads sharply. The big toe itself lays down again to the other side, so to the little toes. The joint at this origin gradually becomes more prominent and can lead to severe chafing and inflammation while walking.

According to the foot arch is now supported thanks to the use of the woven structural sole from below, so as to avoid a crushing of the arch of the foot down to form the gutter effect. Thus, by using a longitudinal flexibility allowing, but a transverse stability forming structural sole increases the footprint and thus made the stand safer. Thus, the use of a sole chassis with a corrugated structural sole forming the topsheet results in a more uniform loading of the shoe over a larger area.

Responsible for the aforementioned, unfavorable gutter effect is not the weak muscles of the foot, but the unfavorable shape of conventional shoes. The foot has to adapt to the shoe, it is deformed abnormally and his muscles inadequate. A lightwight shoe (eg a wedge-shaped sports shoe) only simulates the foot a directness of the power transmission, which is not achieved, because through the soft material of such a sports shoe is the foot pretend only the uneven surface of the tread, so that Foot is not supported by the flexible outsole.

A further significant advantage of the use of an at least two-part formed sole chassis with a corrugated structured sole designed as a front leaf is that the spring force of the structural sole always achieves a restoring effect of the front cap of a shoe which carries such a sole chassis. It is counteracted the so-called beak effect, because especially with pointed women's shoes it comes to the unwanted placement of the toe of the shoe as permanent deformation, so that the front of a particularly pointed trained lady's shoe, beaking upwards and this is prevented by the use of the sole of the invention.

According to a preferred embodiment of the inventive concept it is provided that the rigid rear sheet is additionally reinforced in the direction of its longitudinal axis by a steel joint (hinge spring).

It is a hinge spring, which is also referred to as a steel joint and the z. B. with an adhesive (Agokleber) or riveted to the underside of the insole is connected.

Likewise, it is provided in a development of the invention that the back sheet is designed as a total footbed or as a straight planar piece or as a ball heel.

Likewise, it is provided in a development of the invention that the sole of the invention is only loosely inserted or glued into a shoe.

However, a conventional shoe upper is preferably front swept using the sole of the invention and the back tweaked.

Alternatively, a shoe constructed with the sole chassis according to the invention may also be tweaked over its entire length over a last.

According to the invention, it is therefore provided that the sole chassis according to the invention replaces the conventional insole of a shoe.

For shoes with a heel, especially women's pumps or other shoes, which have a relatively large blast, it is preferred if the sole chassis itself is formed as an insole, which merges towards the bile side of the foot beyond the bending edge in a flexible front sheet and with this is connected, wherein the flexible front sheet either formed itself as a structural sole or at least partially connected to the wave structure having structural sole.

Therefore, when the term 'structural sole' is used in the following description, this may mean various embodiments:
In a first embodiment, it may be provided that the, the insole forming structural sole is provided on its upper side facing the foot with an additional cover and is connected at the bottom with an outsole.

The structural sole according to the invention may also have lateral, upstanding side cheeks to support the side surfaces of the foot on the outer sides and thus counteract the undesirable gutter effect. Such side cheeks may preferably be arranged in the bile region of the foot as a lateral boundary of the structural sole. Thus, the foot is also supported laterally and not only opposite the tread.

The subject of the present invention results not only from the subject matter of the individual claims, but also from the combination of the individual claims with each other.

All information and features disclosed in the documents, including the abstract, in particular the spatial design shown in the drawings, are claimed to be essential to the invention insofar as they are novel individually or in combination with respect to the prior art.

In the following, the invention will be explained in more detail with reference to drawings illustrating several execution paths. Here are from the drawings and their description further features essential to the invention and advantages of the invention.

In 1 and 2 are two different embodiments of a sole chassis 32 . 33 shown. This in 1 illustrated sole chassis 32 consists of a structural sole arranged in the front foot area 1 which extends at least to the bale area of the human foot and which has a wave structure 2 having.

At the rear it is with a steel joint 21 over a rivet 22 connected, wherein gem. 2 the steel joint 21 is designed as a rigid metal strip, which extends through a longitudinally extending longitudinal bead 28 is formed rigid.

Such a sole chassis 32 can therefore be installed directly as an insole in a shoe, which as additional measures is only necessary that the rear part of the steel joint 21 is connected by means not shown connecting means with a paragraph.

The 3 shows as an extended embodiment opposite 1 that the back leaf 14 of the sole chassis 33 is formed rigidly so that the in itself already bending poor rear leaf as a flat part still in addition in the direction of its longitudinal axis with the aforementioned steel joint 21 is connected, with the front area of the backsheet 14 with an overlap area 29 with the back part of the structural sole 1 overlaps and there with the help of a rivet 22 with the structural sole 1 connected is.

This in 1 illustrated sole chassis 32 So it is formed in two parts and consists of the flexible front sheet 15 , which through the structural sole 1 is formed and the front sheet 15 attaching steel joint 21 which the rigid rear leaf 14 formed.

The sole chassis 33 to 3 is, however, formed in three parts, because it consists of the flexible front sheet 15 in the form of structure sole 1 and from the rigid rear leaf 14 , which consists of a sheet-like, flat and rigid plastic material which on the inside or outside in addition to the steel joint 21 is stiffened.

The invention also includes embodiments in which the sole chassis consists of more than three parts. Such multiple parts may be covers, multiple partitions or the like.

The 4 shows the use of a sole chassis after the 1 and 2 when building a shoe, a heel 10 having.

The front sheet 15 is due to the structural sole according to the invention 1 formed, which is still covered at the top by a support.

The structural sole 1 is over a rivet 22 with the steel joint 21 connected, which in its rear area over another rivet 22 with the rigid rear leaf 14 connected is.

The steel joint 21 extends into the area of a paragraph 10 , the one with the back leaf 14 connected is. The distance 31 is a measure of the tightening of the foot.

In the 4 It is clear that the wave structure 2 having structural sole 1 counteracts the unwanted beak effect. Will namely during walking the structural sole 1 in the direction of the arrow 12 bent upwards, causes the spring material of the structural sole 1 a restoring force in the direction of the arrow 12 ' whereby always a straight and flat front cap of the shoe thus constructed is achieved. Due to the restoring force of the structural sole, a turn upwards caused by the unwanted beaking of the toe cap is always eliminated and straightened.

The 5 shows further details of the support of a forefoot 37 , where it can be seen that the structural sole 1 even laterally obliquely upward side cheeks 44 which may be the forefoot 37 give additional lateral stability. The length of the side cheeks 44 should be chosen so that at least the forefoot is bordered at least partially laterally with his ball of the foot.

Out of a total of five given foot bones, it is merely shown that the body weight is substantially above the middle of the forefoot just above the middle toe 40 in the direction of the arrow 41 on the top of the structural sole 1 is introduced, which preferably has a convex arc shape 45 so as to provide a counterforce 43 opposite to the arrow 41 unfold registered body weight.

It is therefore the unfavorable evasion of the big toe bones 39 in the direction of the arrow to the left acc. 5 Counteracted because a crushing of the arch of the foot through the arched shape 45 the structural sole 1 and the application of a counterforce 43 is avoided. Thus, the arch can not be flat on the footprint 42 be permanently pressed and deform disadvantageously.

The 6 shows a sole according to the invention for a flat shoe, at the same time as a replacement for the aforementioned rivet joints with the rivets 22 shown is that the rear end of the structural sole 1 a flexible bending edge 16 forms and in the overlap area 29 with the rigid rear leaf 14 in the area of a fortification 38 with the back leaf 14 connected is. This attachment 38 can be designed as an adhesive bond or as a forward open pocket in the back sheet 14 into which the back end of the structural sole 1 plugged in and fixed there.

It is always important that the structural sole 1 extends at least over the forefoot of the human foot and a restoring force in the direction of the arrow 12 ' while walking towards the footprint 42 generated.

The 7 shows the aforementioned beak effect, where it can be seen that in a sling pump 9 that has a relatively high heel 10 wears while running the toe cap 11 constantly in the direction of the hatched drawn fore cap 11 ' is deformed, leaving a permanent deformation of the toe cap 11 ' given is. Here, the structural sole according to the invention acts 1 contrary, which has a restoring force in the direction of the arrow 12 ' gem. 4 and 6 created to the unwanted Aufschnabeln the front cap 11 counteract.

The 8th and 9 show further details of the structure of the structural sole according to the invention.

It preferably consists of a spring steel material or a plastic material, which gem. 9 a wave structure 2 comprising a series of mutually parallel angled bends 3 . 4 is formed.

The mutually angled bends 3 . 4 thus form at their bottom transverse grooves or waves 5 , which are arranged obliquely to the longitudinal axis of the structural sole parallel and at a mutual distance from each other. In the area of (sloping) bends 3 are recesses in the material of the structural sole 6 provided, which are preferably formed as bores. The recesses 6 serve on the one hand to produce an air passage through structural sole 1 and on the other hand, however, they also serve as anchoring means for anchoring in a plastic material or for adhering an outsole or for foaming the structural sole 1 in a plastic construction.

It can be seen that when one on the structural base in the arrow directions 7 acting force, which is capable of adapting to foot movement in accordance with foot and perform a walking movement (rolling motion) of the foot under best adaptation to the foot, the wave structure 2 the foot conforming to a corresponding footprint 42 (Soil) rolls.

The 9 further shows that excellent lateral or lateral stability under the action of forces in the directions of the arrows 8th is achieved without causing undesirable deformation of the structural sole.

The angle between the bends 3 . 4 and the longitudinal axis 19 is about 97 °, because at this angle, the human foot directed obliquely forward performs its rolling motion. The angle 20 Corresponds therefore exactly the pronation direction of the human foot while walking.

The 10 shows a sole chassis in the form of an insole 13 that from the relatively rigid rear leaf 14 exists, which with a paragraph 10 connected, wherein the flexible front sheet 15 on its upper side with the structural sole according to the invention 1 connected in the region of an overlap area 29 with the front end of the rigid rear leaf 14 connected is.

This results in the connection area between the backsheet 14 and the front leaf 15 a bending edge 16 so the front sheet 15 in the direction of the arrows 17 swiveling to the rear leaf 14 is trained.

Again, it is shown that in the longitudinal direction of the structural sole 1 excellent flexibility while in the transverse direction 23 the structural sole 1 is formed stable deformation.

Consequently, there is always a resilience of the front end of the insole 13 when the insole 13 while walking in the direction of the arrow 24 is bent down.

The 11 shows the structure of the insole 13 to 10 in the bottom view.

Here it can be seen that the rigid rear leaf 14 , which is coated with a rigid plastic, in addition in the middle area still by the aforementioned steel joint 21 is reinforced, which with the two rivets 22 on the back leaf 14 riveted.

In the overlap area 29 is the structural sole 1 with the front end of the back leaf 14 connected, wherein such a connection can be designed either as a slide-in pocket, as an adhesive connection, rivet connection or latching connection.

The 12 shows as another embodiment, a ladies pumps 30 whose shaft 27 with a lining 26 is dressed and the upper 25 still decorated in a certain way. The structural sole 1 can be covered at the top with a cover, with an insole 35 indicated only by dashes. The underside of the structure sole 1 is with the outsole 36 covered. In the area between the top of the outsole 36 and the underside of the structural sole 1 can a ball mass 34 be arranged.

Here, too, the structural force is due to the spring force 1 counteracted the unwanted beak effect, because when kinking the forend 11 this always in the direction of the arrow 24 moved back to the footprint and may be kept constant.
