Description

The invention relates to a shoe system for producing a complete shoe with a high heel,
consisting of an insole arrangement, an outer outsole to be arranged on the underside and a stabilizing element with a heel holder part produced as an elastic workpiece made of a stable hard material, as well as a heel to be fastened thereto,
wherein the shoulder on its side facing the insole assembly has a receiving device with a negative recess corresponding to the shape of the heel holder part, the shoulder can be secured with the heel holder part of the stabilization element by lockable fastening means in the form of a latching and / or plug-in device,
the heel holder part projecting as an approach and the recess of the heel are dimensioned and / or form-fit to one another in such a way that the heel can be firmly connected to the heel holder part in cooperation with the lockable fastening means,
further comprising a shoe upper to be fastened to the insole assembly, wherein the stabilizing element widens an on the underside in the heel area, integrally molded, acting as paragraph holder part, centrally projecting to the shoulder down approach.

A shoe system of this kind is from the US-A-4,835,884 known.

Furthermore, the invention relates to a shoe made of such a shoe system, in particular a women's shoe with expiring in a heel spot paragraph.

Conventional shoes with a heel that runs off into a small heel and thus has a cross-sectional area the size of a penny, at least in the lower part of the heel, and is referred to as a penny heel, are known. Such shoes are usually (but not necessarily) made in the form of women's shoes and may have heels of different heights. In particular, comparatively high heels of about 10 or more centimeters are known. Appropriate shoes can also be equipped with a heel of 3 or less centimeters.

All shoes of this type are usually characterized by a comparatively filigree heel and a thin insole and insole, which provide the foot only a flat contact surface. As a result, the underside of the foot touches the insole and its insole only at some points (toes, bale, heel).

The main load is on the forefoot bale as the foot pushes down by gravity on the more or less oblique plane of the insole of the shoe. Due to the thin insole, these models look very elegant.
Bending of the insole or the insole of such known shoes with pointed heel under load from above through the foot is prevented by a steel spring, which is applied to the insole.

The construction is still so thin that these models continue to look very elegant. The attachment of the paragraph is done by an additional screw the paragraph to the insole. Due to the screwing the insole in this area of the heel must be retrofitted with leather or the like, otherwise the screw would be visible and felt.

Such fashion shoes are manufactured in large factories in large quantities in order to produce these inexpensively. There are also very expensive manufactories with very small quantities.

In order to be able to produce such fashion shoes inexpensively even in small factories or with a small group of workers, according to the DE 32 23 853 A1 a shoe system for making a fashion shoe is provided, which consists of several basic components and thereby has an anatomically formed according to the foot insole heel holder unit, a removable heel with a fastening device, an upper part of the shoe and an outsole.

The insole heel-holder unit is formed by a body of plastic material sandwiched between upper and lower layers of sheet-like material.

To assemble the shoe, the insole heel holder unit is inserted into the top of the shoe and secured by a heel hold, whereupon the outsole is applied to the underside of the front portion of the upper and a heel of selected height and configuration is removably mounted.

For this purpose, the insole heel holder unit is provided with a heel holder part which is integrally formed thereon and projecting from this centrally to the shoulder down, wherein the heel holder part has an assembly aid in the paragraph. For this purpose, a recess is arranged in the heel area, wherein the heel holder part is formed by an integral downwardly directed projection, which can be introduced in the recess and releasably secured by screwing.

Due to this special technical construction of insole-heel holder unit and in the paragraph applied recess for heel holder part can be attached to the shoe in retrospect different heels, be it visually or from the dimensions.

The paragraph should have a height between 2 cm and 8 cm, where he is wide, medium or slim formable.

The main part of the heel holder is injection molded from nylon or other plastic material commonly used in the manufacture of shoe heels.

To manufacture the insole heel holder unit, two neatly punched sheet-like layers are placed in an injection mold. The upper and lower surfaces of the sheet-like layers are respectively convex and concave. While the two sheet-like layers are held in the injection mold, a certain amount of plasticized resin is injected into the injection mold so that a thin lens-like layer is formed between the two sheet-like layers.

This plastic material of the lens-like layer cures on cooling and solidifies, so that the two sheet-like layers are combined with it to form a plastic body and can be removed as insole heel holder unit of the injection mold. As the material of the plastic body thus formed, the same nylon material, ABS material or polyurethane or the like is preferably used as is commonly used in the production of solid but flexible insoles and soles of fashion shoes.

• Zunächst bleibt die Herstellung eines Schuhs nach der DE 32 23 853 A1 insofern aufwendig und kostenintensiv, als eine Innensohlen-Absatzhalter-Einheit in Form eines mehrschichtigen Kunststoffkörpers aus in Abstand befindlichen blattförmigen Lagen in einer Spritzgussform herzustellen ist, wobei der Kunststoffkörper aus starrem Nylon-, ABS-Material oder festem Polyurethan gebildet wird. Er stellt insofern eine starre, im Wesentlichen nicht verformbare Einlage dar, was ebenfalls von Nachteil ist. Außerdem ist trotz der konkaven bzw. konvexen Ausbildung der oberen und unteren blattförmigen Lage die Ausbildung eines anatomischen Fußbettes nur unzureichend möglich.

The manufacture of a shoe with a high heel from the components of a shoe system according to the DE 32 23 853 A1 however, has many disadvantages:

• First, the production of a shoe remains after the DE 32 23 853 A1 insofar consuming and costly than an insole heel holder unit in the form of a multilayer plastic body is made of spaced leaf-shaped layers in an injection mold, wherein the plastic body of rigid nylon, ABS material or solid polyurethane is formed. It represents insofar a rigid, substantially non-deformable insert, which is also disadvantageous. In addition, despite the concave or convex training of the upper and lower leaf-shaped layer, the formation of an anatomical footbed insufficiently possible.

For attachment of the paragraph requires a in this already introduced in the injection mold heel holder part, which special and special tools, in particular a screw of the paragraph is to create this and the paragraph. These assembly aids are to lay out insofar as the paragraph should be mounted removable according to a height and training to be selected. In particular, paragraphs with narrow heel stains so far no absolutely firm support of the paragraph to the insole assembly used can be achieved. In addition, due to the screw connection also at the DE 32 23 853 A1 the insole in the heel area subsequently be covered with leather or the like, otherwise the screw would be visible and felt.

According to the DE 10111 229 C1 is the production of an insole of two superposed soled components, namely a midsole and a support member made of plastic and high mechanical stability compared to the properties of the midsole used known, wherein the support member formed from a nylon modification or a thermoplastic polyurethane-based elastomer becomes.

Support element and midsole have a material based on the same polymer, but this each has different mechanical properties. The support element has different mechanical properties than the midsole because of a different degree of crosslinking of the macromolecular substances it contains than the midsole EVA.

The joining of the midsole and the support element takes place in a vulcanizing mold without connecting means only by application of heat and pressure.

The production of a shoe according to the doctrine of DE 10111 229 C1 the following disadvantages: No anatomical training for an insole is provided. The choice of materials is limited because vulcanization without bonding agents is only possible if the midsole and support element have the same polymer base. In contrast, more elegant materials can not be used. In addition, the achievable minimum thickness of the insole thus formed is comparatively high. Such sole elements with support element are therefore primarily used for sports shoes and are insofar particularly not suitable for the production of elegant heeled shoes.

According to the US-A-835,884 is a shoe system consisting of an insole assembly known, wherein a stabilizing element is formed from a molded sole shaft and an insole.
The sole shaft has a section to come to rest in the middle foot region and a subsequent section to come to rest to the heel region with an integrally formed heel part. Further, a sole shaft amplifier. The insole is formed from an upper and lower cover layer, between which layers the middle sole shaft section is fixed.

The sole shaft is injection molded from a stable hard material and the insole made of a corresponding material made of plastic fiber material. The composite part of sole shaft or sole shaft amplifier and insole is formed without an outer shock-absorbing layer. On the inside of the shoe, on the other hand, a special cushioning sole is created.

From the EP1-602 294 A1 A foam insole is already known, which has a Hartkemteil formed as a molded part of thermoplastic polyurethane, which is insofar thermoplastically deformable. The outer layer surrounding the hard core part is made of a soft plastic with good resilience, wherein a flat footbed is formed in the top of the layer, or the thin foam around.

Based on the described prior art, according to the DE 32 23 853 A1 and the US-A-4,835,884 , The invention has for its object to provide an improved shoe system for a shoe with a high heel, especially with an expiring in a heel spot paragraph, or an improved shoe formed therefrom.

Compared to the shoe system according to the DE 32 23 853 A1 Furthermore, the specific task is given to create a shoe with paragraph, especially a women's shoe with expiring paragraph in a paragraph heel, the structure of the shoe and heel attachment can be done via an insole assembly with outer outsole without using an insole and a steel spring to be arranged there. On the upper side of the insole arrangement, the upper part of the shoe should be fastenable directly,
wherein on the underside of the insole assembly immediately the attachment of a leaking paragraph in a mere paragraph heel should be possible,
and thus a high-strength connection between insole assembly and paragraph is given.

The overall strength of the outsole assembly with outsole should be as thin and elegant as possible with conventional heeled shoes, which have a thin insole with a threaded heel, and steel springs that prevent flexing of the insole and insole when loaded.

The invention is based on the idea, while maintaining the elegant look of such women's shoes with paragraph the foot by an additional footbed provided in the top of the insole assembly as much as possible over the entire foot length to give optimum support through the contour of the footbed, so that anyway Unhealthy standing and running on heels with heels is made as comfortable as possible and the strains on the body when walking and standing are minimized. The insole assembly is intended to consist of a dimensionally stable plastic with foamed outer soft area with good resilience, inasmuch as the contour of the footbed can be imprinted directly on the top.

Starting from a shoe system of the type mentioned in accordance with the US Pat. No. 4,835,884 To solve this problem, a shoe system according to claim 1 is provided:

Further, to form such a shoe, a shoe made of the parts of this shoe system according to claim 16.

The shoe system according to claim 1 is further characterized in that it comprises a stabilizing element, which is made of a dimensionally stable, hard and at the same time elastic material. This stabilizing element can thus form the backbone of a shoe made from the shoe system according to the invention. On a the additional stabilization of the stabilizing element serving steel spring, as this is to be used in a shoe provided with insole, can be dispensed with.

The stabilizing element is surrounded by a soft, foamed layer. This creates the opportunity to dispense with an insole, since the soft layer is also provided on the top, ie the foot-facing side of the stabilizing element and thus can form a pleasant for the foot surface. Therefore, the insole can either be omitted completely or provided only in a simpler design. The preparation can be further simplified by the fact that the layer in a simple process on the stabilizing element is sprayed on. The outer skirting by a soft material, wherein the stabilizing element comes to lie in the middle in this foam so far, while allowing optimal support of the entire sole of the foot in the shoe, so that an uneven load on the sole of the foot and unhealthy load on the body is largely avoided.

The stabilizing element furthermore has a shoulder formed on the underside in the heel region, acting as a heel holder and projecting downwards. The heel is fixable with this paragraph holder part of the stabilizing element of the insole assembly. This is achieved in that the shoulder has a corresponding negative recess into which engages the projecting shoulder of the paragraph holder part. The projecting approach of the paragraph holder part and the corresponding negative recess of the paragraph are each dimensioned so that they fit each other positively and or non-positively. In addition, lockable latching or plugging means or other suitable fastening means are provided which cause the paragraph as a whole is firmly connected to the paragraph holder part.

Overall, this arrangement of heel and paragraph holder is a cost-effective and fixed mounting a paragraph given. In particular, a screwing of the paragraph, which regularly requires an additional cover of the screw head, can be dispensed with, without jeopardizing the secure connection of heel and remaining shoe. The manufacture of the shoe is further simplified in that the stabilizing element not only makes the insole superfluous, but at the same time also has the integrally formed heel holder unit.

The required number of components for shoe production is thereby further reduced and the manufacturing process further simplified and cheaper. Furthermore, on the stabilizing element, which in this respect represents the main component of the shoe, simply attach differently designed shoe tops and heels, which increases the flexibility in and for the production of different shoe models.

• Durch die neue Konstruktion des Schuhsystems gemäß Anspruch 3, wonach die Umschäumung an der Oberseite des Stabilisierungselementes ein Fußbett bildet, berührt die Unterseite des Fußes auf ihrer gesamten Fläche das weiche umschäumte Kunststoffmaterial der äußeren Schicht des Stabilisierungselementes. Die Innensohlenanordnung bildet somit ein Fußbett über die gesamte Unterseite des Fußes.

By preferred embodiments, as described in claims 2 to 15, further advantages can be achieved:

• By the new construction of the shoe system according to claim 3, wherein the foam at the top of the stabilizing element forms a footbed, the underside of the foot touches on its entire surface the soft foam-coated plastic material of the outer layer of the stabilizing element. The insole assembly thus forms a footbed over the entire underside of the foot.

This distributes the burden despite the oblique position over the entire bottom of the foot, the ball of the foot compared to conventional shoes with heels is significantly relieved. This applies in particular to the underside of the foot, where the inner transverse arch of the foot is correspondingly strongly supported by the foamed plastic material of the outer layer of the stabilizing element.

In this respect, there is a strong visual difference compared to conventional shoes with high heels.

The foot stands in this area, however, in the conventional shoes with heel and insole clearly hollow, so no support.

In particular, in the formation of the stabilizing element according to claim 2 of a stable hard but elastic plastic part, which is provided according to claim 1, that the stabilizing element surrounding the foamed outer layer of a soft plastic material with good resilience and thereby already at the top of this layer Fußbettbereich is molded in the form of an anatomically shaped footbed, it is possible to keep the overall thickness of the insole assembly used despite the indentation of the footbed extremely thin and elegant, while at the same time in this bare insole assembly made of plastic with a fixed heel compared to shoes with heels comparable stability is given , which have an insole with steel spring to stabilize them and a screwed-on heel.

The heel is made of a robust plastic, e.g. a thermoplastic material with good abrasion values, in which, according to an advantageous embodiment of the subclaims, a steel pin with holding mandrel is injected.

The heel of the shoe is also made of a stable material, e.g. ABS made, but this is very hard but scratch, impact and break-proof.

Inside the paragraph, a hollow steel pin is provided, in which the mandrel of the steel pin of paragraph heel is mountable.

According to dependent claim 5 perforation holes are created by the stabilizing element to improve the connection of the stabilizing element and its outer layer umschäumter. To improve the stability of the insole assembly projecting longitudinal ribs are formed at least on one of the outer side of the stabilizing element in the longitudinal direction of the sole assembly, inasmuch as bending of the sole assembly is prevented under load of the shoe with heel from above through the foot even under heavy load.

The layer surrounding the stabilizing element consists of a urethane-based thermoplastic elastomer, in which respect an elastic material with very good wear resistance and high resilience is provided.
An anatomically shaped footbed can be molded into this material to the extent that all essential components of such an anatomical footbed are given, ie a deep heel cup, which gives the foot firm hold.
an inner and outer longitudinal arch support, which give the foot balance when it hits the floor and which provide a natural, proper footing
a toe grip, which ensures optimal toe guidance for a natural rolling motion of the foot,
a flexible bedding material with a particularly high level of comfort and an outer bedding edge, which is pulled up laterally on the outer edge of the bedding and embeds and protects the foot.

According to an advantageous embodiment and especially for the comfortably padded storage of the foot in the area of the pad and heel recesses for inserting a heel pad and a transverse vault helix are further provided in the anatomically shaped Fußbettung, which are softer than the foamed layer of the stabilizing element (dependent claim 4).

In the following advantageous embodiments of the shoe system will be described with reference to a ladies sandal with heel strap and two leash with buckle with reference to the drawings.

The women's sandal (20) points accordingly FIG. 1 and 3 a paragraph (2) in the amount of about 10 cm, which already in the top half tapers to a cross-section of a penny heel and bottom of the paragraph a heel patch (1) is created. The height of the paragraph is exemplary. Also conceivable would be higher sales or significantly lower sales.

Paragraph mark (1) and paragraph (2) are fastened by a steel pin (17) with protruding mandrel injected in the heel spot, this mandrel being inserted into an internal hollow steel pin (18) of paragraph (2), the heel being made of ABS Plastic exists.

The structure of paragraph (2) is in FIG. 4 shown. For attachment, it has a negative recess (10) for a heel holder part of the insole assembly (3,4).

The negative recess (10) at the upper back of the paragraph corresponds to a wedge-shaped, integrally formed on the underside in the heel area, acting as heel holder portion approach of the stabilizing element (3), which in FIGS. 5 and 6 is shown with its top.

In order to produce the insole arrangement (3, 4) of the ladies' sandal, the stabilizing element (3) is arrested in a production mold of the insole assembly (3, 4) in such a way that an outer foam layer (4) is formed. of the stabilizing element (3), the outer layer can be injected around the stabilizing element.
The outer layer is foamed, which consists of a stable, but soft material with good resilience (TPU).

This material is elastic and also has good wear resistance in addition to the desired resilience.

The connection of the outer overmolded layer (4) to the stabilizing element (3) is increased by perforation holes (7a, b, c) according to FIG FIG. 5 in the stabilizing element (3) are applied, these serve that the thermoplastic polyurethane of the layer (4) can flow through these holes, wherein the parts to be joined (3,4) are thus virtually inseparable.

Already due to the rigidity of the stabilizing element (3) bending of the stabilizing element or the insole assembly (3,4) and the footbed (15) formed on the upper side is prevented by the foot from above when the shoe is loaded.

There is no need for conventional high heel women's shoes, and thus none of these generally used steel springs to prevent sagging.

Only by this special connection of the stabilizing element (3) and the surrounding foamed outer layer (4), the insole assembly and its construction can be made so thin that maintaining the elegant look of conventional women's shoes with heels and insole and arranged steel spring despite the optimal Support in the footbed is given.

On the upper side of the finished insole assembly (3,4) with internal stabilizing element (3) and outer footbed (15), a heel pad (5) and a transverse archepolotte (6) are preferably applied.

For this purpose, recesses (12, 13) are provided in the footbed (15).

After insertion of these parts, the entire insole assembly with the heel already fastened to the stabilizing element (3) with a thin layer, e.g. Leather covered. This is accomplished with a special last which has the exact negative shape of the footbed (15) or insole assembly (3,4) and also has special burrs so that all prominent features such as the contours of the foot marks in the footbed also after being covered remain distinctive and the fabric has no wrinkles, blisters or the like.

In addition, the soft latex parts are not compressed by corresponding recesses in the last, thereby remain elastic and in shape.

Thereafter, the shoe upper (16) (shaft) depending on the desired model on the related insole assembly (3,4) mounted ("tweaked").

In the modified stabilizing element (3 ') according to FIG. 11 stands at the bottom in the heel area before a cuboid spacer member (9). Accordingly, the according to FIG. 10 modified paragraph (2 ') to be fastened on its side facing the underside of the sole arrangement has a negative parallelepiped-shaped recess (10') corresponding to this shape.

Opposite the in FIG. 5 Stabilizing element shown from the top, which except for through perforation holes (7a, b, c) has smooth outer sides, so no reinforcing projections or ribs are in the remote stabilizing element (3 ') to improve the stability (bending strength) on the bottom two spaced longitudinal ribs (8a, b) guided in the longitudinal direction of the stabilizing element (3 '). It is thus prevented sagging of the sole assembly under load of the shoe with heel through the foot.

After the paragraph (2 ') has been finished as desired by the designer (painted, galvanized, covered with leather, etc.), this is connected to the insole assembly (3', 4) high strength.

This is achieved by a bond and by a positive and non-positive connection of the cuboid paragraph holding part (9) and this part receiving negative recess (10 ').

In traditional shoes with heels and insoles additional fastening of the insole with the heel is necessary to ensure the necessary stability.

In the present construction, this is not necessary due to the stability achieved between the parallelepiped paragraph holder part (9) of the stabilizing element (3 ') and the recess (10') in the shoulder (2 ') and the optionally additionally provided bonding.

Since an additional screwing of heel and stabilizing element is not necessary, according to the invention is thus avoided in particular that due to a screw, as provided with insole, subsequently the area of the insole (heel) must be covered with leather or the like. Thus, the elegant look of the leather-covered insole assembly (footbed) is preserved without being affected by seams or cut edges of additional cover layers.

For the completion of the shoe is still on the underside of the insole assembly (3,4) nor an outsole (11) to attach.

The installation of an additional insole does not occur according to the invention.

According to Figure 10-12 Thus, in a modified embodiment, the attachment of the paragraph on the modified heel holder part (9) and a negative shaped recess (10 '), wherein the block-shaped approach passes under gradation in an additional smaller approach. Laterally, as in the embodiment according to Figure 13-15 an additional Attachment via additional mounting and fixing pins (21, 22) as well as openings (23, 24) of locating holes provided for this purpose.

In the modified embodiment of the stabilizing element (27) according to the stabilizing element (3) without projections or longitudinal ribs according to FIG. 5 In addition, in the middle of a longitudinally extending steel spring (29) is embedded. By this an additional reinforcement of the stabilizing element is achieved and thus reliably prevents bending under load of the insole assembly and the shoe formed therefrom, even with larger weights and forces.

According to the stabilizing element (3 ') of FIG. 11 is according to FIG. 17 a change to this provided, wherein the stabilizing element (28) shown there also has an additional steel spring (30) extending from the area of paragraph paragraph part (9) to over the length of the stabilizing element (28) at least to the area under the transverse arch support of forming, anatomically shaped footbed (15) of the shoe extends. In addition, continue as in FIG. 11 Longitudinal ribs (8a, b).

The stabilizing elements (27,28) with recessed steel spring (29,30) are each made by injection molding by hybrid technology, in which respect a firm connection of the different steel and plastic materials used.

The stabilizing elements (27,28) are also formed of an acrylonitrile / butadiene / styrene material, wherein also the paragraph to be used (2,2 ') is formed of the same plastic material.
