The sole part has a front, a middle and a rear sole section and has a mechanism for setting the sole curvature in a transition area between the front and the middle sole section. The mechanism has a rotatable reinforcing element which is provided such that it can assume a first angle of rotation which effects a first curvature of the sole in the transition area and can assume a second angle of rotation which effects a second curvature of the sole in the transition area, wherein the first curvature of the sole is different from the second curvature of the sole.

Description

Sohlentei!

The present application claims priority to German Patent Application No. 10 2012 213 809, which is hereby incorporated by reference in its entirety into the present application.

The present invention relates to a shoe for use with interchangeable heels and a sole portion for such a shoe, in particular the invention relates to a women's shoe for use with heels of different heights and a sole part and exchangeable heels for such a shoe. The sole member may have one or more mechanisms for adjusting the curvature in one or more sole regions.

High women's shoes (so-called high heels) can cause considerable discomfort and even pain with long wearing time. Thus, when wearing high heels in particular to a one-sided load on the foot, since a large part of the body weight on the forefoot loads. In the long run, this can lead to different deformations, for example countersinking or spreading feet. In addition, there is also a high load on the bale, which can lead to signs of wear of the big toe joint. Also, back pain and shortening of the calf musculature are associated with the wearing of high heels.

Regardless, high heels enjoy great popularity and are often used, for example, to emphasize certain body regions by a specific posture or to look bigger. However, high-heels are often only worn on certain occasions and women often carry replacement shoes with them to change as needed, especially to counteract the disadvantages described above.

EP-A1-2 074 900 discloses a shoe with an adaptable shoe sole part and a replaceable shoe heel. The heel has a pressure generating element which is intended to act on a pressure transmitting element in the shoe sole part and to exert pressure in the direction of the toe. This leads, according to EP-AI-2 074 900, to a deflection of a middle sole section upwards. The present invention has for its object to provide improved shoes and sole parts, in which the heel can be changed, as well as improved heels for such shoes. This object is achieved with the merlanals of the claims. Preferred embodiments can be found in the dependent claims.

The sole part according to the invention may have a front, a middle and a rear sole portion. These portions may according to embodiments of the invention substantially correspond to a ball of the foot or forefoot, a foot bridge or midfoot portion or a heel portion of the sole portion. The sole portion may include an insole, a sock, and / or an outsole, and may be used in place of an insole. Insole, insole and outsole may each be formed as one piece or by a plurality of segments.

The term "longitudinal direction" in the context of the present description preferably refers to the direction corresponding to the longitudinal direction of the foot from the heel ("back") to the toes ("front") the term "sole longitudinal direction" is also used in connection with heels that are not necessarily mounted on the sole part. The "sole longitudinal direction" in this case denotes that of the coordinate axis which extends parallel to the ground plane along the sole longitudinal direction when the heel is mounted on the sole part, corresponding axis.

The invention is based on the idea that the optimum course of the sole, in particular the buckling in the area of the foot and / or the heel, should vary depending on the heel height.

According to embodiments, the sole part according to the invention has a front, a middle and a rear sole portion and a mechanism (first mechanism) for adjusting the sole curvature in a transition region between the middle and the rear sole portion (first transition region). The mechanism preferably has a stiffening element (first stiffening element) that is designed so that it can be pushed away from the sole part in the region of the rear sole section in order to reduce the curvature of the sole part in the first transition region and / or in the region of the rear sole portion can be pressed to the sole part to increase the curvature of the sole part in the first transition region. The mechanism, stiffener, and overhang are referred to as a "first" mechanism, "first" stiffener, and "first" transition region, and may be isolated from a "second" mechanism, described below, or in combination therewith be.

The first stiffening element is preferably relatively stiff, whereas the sole part is preferably made relatively flexible, at least in the first transition region. The first stiffening element is therefore preferably stiffer than the sole part, at least in the first transition region. The transition region may be made more flexible than the rear and / or middle sole sections. Alternatively or additionally, a joint is provided in the first transition region, so that the middle sole portion is pivotable or tiltable toward the rear sole portion along a rotation axis. The axis of rotation preferably extends transversely to the sole longitudinal direction. The rear sole portion may be pivotally connected to the first stiffening member and / or pivotally mounted in the first stiffening member, wherein the joint may be provided, for example, at the front end portion of the rear sole portion.

The sole member may include a leaf spring fixedly connected to the rear and middle sole portions to give the first transition region a defined curvature. This may be advantageous, for example, when using a joint in the first transition region in order to determine the position of the sole sections relative to one another in a neutral state of the first mechanism.

Preferably, a front part of the first stiffening element extends into the region of the middle sole portion and is at least partially fixedly connected to the middle sole portion. According to embodiments of the invention, the front part of the stiffening element is integrally formed with the middle sole portion.

A rear part of the first stiffener extending along the rear sole portion is preferably not fixed to the sole part or not connected to the sole part, so that an angle between the rear part of the first stiffener and the rear sole part is adjustable. When fixing the front part of the stiffening element at the middle sole portion or integral construction, the adjustment of the angle or from the stand preferably leads to adjustment of the angle between the rear and the middle sole portion and thus to adjust the curvature in the first transition region. Preferably, the reduction leads of the angle between the rear portion of the first stiffener and the rear sole portion to increase the curvature. An increase in the angle or the distance preferably leads to a reduction of the curvature. The stiffening element is preferably loose along its entire rear end region from the rear sole portion. The rear end region preferably extends below the rear sole portion.

When changing the sole curvature in the first transition region, the first stiffening element preferably retains its shape substantially or completely. Thus, the angle between the rear end region of the stiffening element and the middle sole portion preferably remains substantially or completely constant when the arc curvature changes in the first transition region.

Depending on the perspective, the rear sole portion and / or the first stiffening element may be formed such that the rear sole portion can be pushed away from the first stiffening element and / or the first stiffening element can be pushed away from the rear sole portion. Here, the rear part of the stiffening element, for example, by means of a wedge-shaped structure on the shoulder, which is pushed between the stiffening element and the rear sole portion, be pushed away from the rear sole portion. The rear end of the stiffening element can for this purpose in the neutral position (ie without heel) be spaced from the rear sole portion.

The first stiffening element according to an embodiment of the invention has a projection. The projection preferably extends laterally or downwardly away from the stiffening element. According to embodiments of the invention, the projection provides at least one surface which extends substantially transversely to the sole longitudinal direction. The normal vector of this surface facing away from the projection preferably faces upwards in the longitudinal direction of the sole and in the longitudinal direction of the heel so that the surface extends obliquely to the plane of the rear sole portion and extends forwards in the sole longitudinal direction away from the plane of the rear sole portion. The projection can be used to adjust the first mechanism and / or attachment of a heel on the rear sole member.

According to further embodiments of the invention, which may be combined with the above, the first stiffening element is provided so as to be extends in the neutral state of the first mechanism in the region of the rear sole portion away from the sole part. The distance between the stiffening element and the rear sole portion preferably increases in the longitudinal direction of the sole to the rear. In this case, the rear part of the stiffening element can be pressed, for example, by means of the heel to the rear sole portion.

The first stiffening element is preferably formed substantially flat and elongate along the central sole portion. At the rear, the stiffener may have a recess through which elements of the second mechanism described below may extend.

The first stiffening element may be formed as a rail which extends along the middle sole portion and is fixedly connected thereto. The rail may have first holes for receiving a first axis, via which the rear sole portion is pivotally connected to the first stiffening element and / or second bores for receiving a second axis, via which the front sole portion is pivotally connected to the first stiffening element. The rail may essentially consist of a flat steel, which is arranged perpendicular to the middle sole portion. It is also possible to use a plurality of (preferably two) rails, which then preferably run essentially parallel or are slightly tapered in the longitudinal direction of the sole to the rear. The rails can be connected by means of pins. Between the rails elements of the second mechanism, elements of a fastening device for the heel and / or elements of a dressing aid for the heel, which will be described below, may be arranged.

The one or more rails may be configured to be inserted from the underside of the middle sole portion into the middle sole portion. They are then preferably attachable by means of a counterpart, which can be inserted from the top of the middle sole portion in the middle sole portion. The counterpart may be a flat plate arranged substantially parallel to the central sole portion, wherein the one or more rails may have recesses for receiving the plate. The plate may optionally be attached to the middle sole portion, for example by means of screws, gluing, welding, snap-fastening, or similar techniques. The rear part of the first stiffening element can run rearward along its course in the longitudinal direction of the sole. The rear part of the first stiffening element can be narrowed in one or more directions. It can thus run in one or more views of the sole part, for example in a view from below and / or in a view from the side. If the first stiffening element is formed by a plurality of rails, the rear part can be formed tapered by these rails converge at least along the rear part. By such a shape can be achieved even with production-related tolerances of the sole part and / or heels a backlash-free attachment of different paragraphs on the sole part.

According to embodiments of the invention, the sole part has a front, a middle and a rear sole portion, wherein the sole part has a mechanism (second mechanism) for adjusting the sole curvature in a transition region (second transition region) between the front and the middle sole portion. The mechanism preferably has a displaceable and / or rotatable Ver stei fungsel ement (second stiffening element), which is provided or designed so that a displacement or rotation of the stiffening element leads to a change in the sole curvature in the transition region. The displacement or twisting of the stiffening element therefore preferably leads to a change in the angle between the front sole section and the middle sole section.

The second mechanism or the second stiffening element is preferably integrated in the sole part or in a shoe sole, which has the sole part.

The mechanism, stiffener, and overhaul are referred to as "second" mechanism, "second" stiffener, and "second" transition region, but may be provided independently of, or in combination with, the "first" mechanism described above be.

The sole part is preferably more flexible in the second transition region than the second stiffening element. The second transition region therefore preferably follows substantially the shape that is predetermined by the second stiffening element. Optionally, the second transition region may be hinged and / or more flexibly configured than the front, middle, and / or rear sole sections. The front sole portion is in this case preferably pivotable with respect to the central sole portion along a rotation axis. The axis of rotation preferably extends transversely to the Sole longitudinal direction. The front sole portion may, for example, be hingedly connected to the first stiffening element and / or be articulated in the first stiffening element.

For the first and / or second stiffening element u. a. Materials such as steel, metals, metal alloys, plastics, composites, etc. can be used. For example, V2A sheet or V2A steel may be considered for the first stiffener, but other materials that have sufficient strength and corrosion resistance may be used. The second stiffening element is preferably made of a resilient material that is not plastically deformed by the bending of the sole when walking substantially and yet has sufficient strength. For example, a spring steel or other alloys with similar properties can be used.

The sole member may include a second leaf spring fixedly connected to the middle and front sole portions to give the second transition region a defined curvature. This may be advantageous, for example, when using a hinge in the second transition region to define a neutral position of the second mechanism.

According to an embodiment of the invention, the second stiffening element is displaceable and is provided so that it can be displaced along the sole longitudinal direction from a first position, which causes a first sole curve in the second transition region, to a second position, which forms a second sole curve in the second Transition area causes. In this case, the first sole curve differs from the second sole curvature.

The second stiffening element is preferably designed as an elongate stiffening sheet. The stiffening element is preferably displaced as a whole from the first to the second position.

The second stiffening element is preferably guided at least in sections in the region of the middle sole section in a guide (eg a rail) which is firmly connected to the sole part, in particular the middle sole section. In this case, it is preferred according to embodiments of the invention that the second stiffening element at least along a front region of the middle sole portion so in a guide and / or to guide in the sole (eg the sole part), that a bending or bending of the second stiffening element is prevented in this area.

In the first position, the second stiffening element preferably does not protrude into the front sole portion. The S ohlenenkrümmung in the second transition region corresponds in this case therefore preferably the sole curve, with which the sole part or the sole was made. If the stiffening element is displaced into the second position, it preferably protrudes into the second transition area and more preferably into the front sole section. As it is guided along the second transition region and / or along the front sole portion (eg, by means of a rail or in an opening of the sole part), the transition region and / or the front sole portion essentially follows the shape of the stiffening element. The shape of the stiffening element preferably predetermines the curvature of the second transition region in the second position.

If the sole has a large curvature in the transition region due to its production (manufacture as a high heel), a stiffening element with a lower curvature or a substantially straight stiffening element can be used in order to reduce the curvature in the second transitional area when placing a flatter heel. If, by contrast, the sole part has a slight curvature in the second transition region (production as a flat shoe), this could be increased by a more strongly curved reinforcing element if a higher heel is to be used.

The second mechanism according to embodiments of the invention further comprises a movement device which is provided or formed so that the second stiffening element during placement and removal of the heel is displaceable. The moving device preferably has a transfer member extending from the rear sole portion to the second stiffener. The transmission member is preferably fixedly connected to the second stiffening element, so that an adjustment of the movement device causes the displacement of the stiffening element from the first position to the second position.

The transmission lens is preferably bendable. This is advantageous for record, even if the curvature in the first transition region is adjustable (eg., By means of a first mechanism).

According to embodiments of the invention, the movement device may be formed as a Bowden cable, wherein the transmission member by a Bowden cable soul is formed, which extends in a BowdenzughüUe. Near the rear end of the Bowden cable core, a driver (eg, a pad) may be provided that can interact with interchangeable heels to permit adjustment of the movement device when placing and / or removing the heel. The driver is preferably firmly connected to the Bowden cable. The Bowdenhülle may be attached to the sole part and / or on the first stiffening element. The Bowden cable may extend through the recess of the first stiffening element.

According to another embodiment of the second mechanism, the second stiffening element is rotatable. It is provided or designed such that it can assume a first angle of rotation which causes a first sole curve in the second transition region, and can assume a second angle of rotation, which causes a second sole curve in the second transition region. In this case, the first hollow curvature differs from the second sole curvature and is preferably smaller.

The second stiffening element can be provided such that the active rotation of the second stiffening element by a user (which can be effected by further mechanical means) leads to a change of the sole curvature in the second transition region. The second stiffening element can therefore act as an active element, which causes a certain arrangement and / or angular position of the middle sole portion to the front sole portion. The middle and / or the front sole portion may be formed as passive elements.

The stiffening element is preferably elongated in this embodiment of the invention and more preferably designed as a shaft. The profile of the shaft can be round or oval (for example, circular), but in principle have any cross-sectional shape (for example, also angular or polygonal). The shaft may have a curved and / or angled segment.

The second stiffening element or shaft preferably extends from the rear sole portion over the middle sole portion to the second transition region, and more preferably into the front sole portion. It is preferably rotatably mounted in a holding device at least in the region of the middle sole portion and / or the rear sole portion. For this purpose, for example, one or more sleeves (eg brass tubes) may be used, which are preferably fixedly connected to the respective sole portion and / or the first stiffening element (eg. B. by gluing, welding, soldering, etc.). Alternatively or additionally, the storage in a corresponding recess of the middle sole member is possible. Preferably, an axial displacement of the second stiffening element in the sole longitudinal direction is prevented by the holding device. The second stiffening element may extend at least in the middle sole portion substantially in the sole longitudinal direction.

In the front end region, the second stiffening element preferably has a first curved and / or angled segment, which has a predetermined, defined curvature. This first segment is preferably at least partially in the second transition region. The first segment may substantially or completely retain its shape upon rotation of the second stiffener. The curvature and / or bending of the first segment preferably remains substantially or completely constant during the rotation of the second stiffening element.

To the first curved segment may connect a front end segment of the stiffening element, which is preferably straight. The front end segment may be movably received on the front sole portion. Preferably, the front end segment is received in the region of the front sole portion in a recess which allows movement of the end segment in the plane of the front sole portion (horizontal). Since the second stiffening element is rotatably mounted along the middle sole portion and curved or angled along the transition region, the rotation of the second stiffening element preferably leads to a pivoting of the front end segment in the recess. Under certain circumstances, the second stiffening element or its front end segment projects further in the sole longitudinal direction into the front sole section when the second stiffening element assumes the second angle of rotation. Under a recess of the front sole portion is also a recess which is provided in a further element which is firmly connected to the front sole portion to understand.

The projection of the first curved segment onto a projection plane which runs along the axis of rotation of the stiffening element and is perpendicular to the plane of the front sole section preferably has a first curvature when the stiffening element assumes the first angle of rotation. Since the stiffening element is rotatably supported along the central sole portion, the front sole portion follows the end segment, so that the projection of the curvature of the stiffening element the angle determined between the front and the middle sole portion or the curvature in the second transition region. The curvature in the transition region can therefore essentially correspond to the projection of the curvature of the stiffening element.

The curved section of the second stiffening element preferably tensions a mental curvature plane, in which the radius of curvature also lies. If the second stiffening element is twisted, this preferably causes a rotation of the plane of curvature. According to embodiments of the invention, the curvature plane is substantially perpendicular to the plane of the front sole portion when the second stiffener is rotated to the second angle of rotation.

The second mechanism according to this embodiment allows by adjusting any rotational angle preferably a continuous adjustment of the sole curve in the second transition region.

The second stiffening element may be designed so that it is rotated by the pushing and / or removing a paragraph. Thus, by pushing and / or removing a heel (which is usually fastened in the rear sole region) in the second transition region, a correct arc curvature can be automatically achieved for the respective heel (i.e., in particular for the respective heel height).

The second Ver stei fun gs element of the inventive sole member may optionally have a lever over which the stiffening element can be rotated. The lever is preferably provided in the region of the rear sole portion and can be rotated depending on the type of heel and / or heel height. The lever may be formed by sliding a sleeve (eg, a brass tube) over the rear end portion of the second stiffening member and bending it together.

According to preferred embodiments of the invention, the lever is provided so that the second stiffening element is rotated when pushing and / or removing a paragraph.

Alternatively or additionally, the second mechanism may be provided with a gear for rotating the second stiffening element. This may be formed, for example, as a worm gear, wherein the stiffening element is preferably provided with a thread and is rotated by an axially displaceable sleeve. In addition, the transmission can also be designed as a gear or rack gear. Alternatively or additionally, the second stiffening element in the rear end region may have a second curved and / or angled segment which has a predetermined, defined curvature. This second segment is preferably at least partially in the first transition region. The second segment may substantially or completely retain its shape upon rotation of the second stiffener. The curvature and / or bending of the second segment preferably remains substantially or completely constant during the rotation of the second stiffening element.

To the second curved segment may connect a rear end segment of the second stiffener tion element, which may be straight, for example. The rear end segment may be movably received on the rear sole portion. Preferably, the rear end segment is received in the region of the rear sole portion in a recess which allows movement of the rear end segment in the plane of the rear sole portion (eg horizontal). If the second stiffening element is rotatably mounted along the middle sole section and curved or angled along the first transition region, the change of the sole curvature in the first transition region and / or the change of the angle between the rear sole section and the middle sole section preferably leads to the rotation of the second stiffening element, which then in turn a waste of the front end segment can be achieved, which leads to a change in the sole curve in the second transition region. Under certain circumstances, the second stiffening element or its rear end segment protrudes further into the longitudinal direction of the sole in the rear sole portion when the second stiffening element assumes the second angle of rotation. The recess in the rear sole portion and / or the second stiffening element can therefore be provided so that the adjustment of the angle between the rear sole portion and the middle sole portion and / or the adjustment of the sole curve in the first transition region when pushing and / or removing a paragraph to twist of the second stiffening element leads. Thus, for example, by correctly setting the first transitional region for the respective paragraph, a correct setting of the second transitional region for the respective paragraph can be achieved automatically and / or simultaneously. Under a recess of the rear sole portion is also a recess which is provided in a further element which is fixedly connected to the rear sole portion to understand. The first stiffening element may extend over the second stiffening element at least in sections. The second stiffening element may extend through a recess in the first stiffener. Alternatively or additionally, the second stiffening element may extend along the central sole section substantially parallel to the first stiffening element, preferably between two first stiffening elements, which are arranged substantially parallel or slightly tapering. The second stiffening element may extend under a counterpart to the fastening of the rails of the first stiffening element.

The second stiffening element may be formed by a plurality of elements (eg, a plurality of separate elements) each of which may be formed in accordance with the foregoing description. In particular, it is possible to form the second stiffening element by two or more shafts to give the sole part a greater stability. Both shafts may comprise a first curved segment and / or a second curved segment as described above, wherein a corresponding front end segment may be disposed in a recess of the front sole portion and / or a rear end segment may be disposed in a recess of the rear sole portion. The two or more waves can be arranged directly adjacent to each other and / or touch, whereby a particularly space-saving design is achieved. The waves may be arranged in a common recess of the front, middle and / or rear sole portion. The two or more shafts may all be arranged substantially in a plane parallel to the front, middle and / or rear sole portion.

The invention further relates to a sole part with one or more attachment means for exchangeable heels. The attachment means may be provided in combination with one or more of the mechanisms described above.

In the region of the rear sole portion, the sole part according to the invention preferably has one or more fastening means for fastening different heels. The fastening means may be provided, for example, on the rear sole portion or on the first stiffening element. The attachment means may comprise one or more projections. The profile of the projection is preferably provided or formed so that it can engage in a recess of the heel and thereby prevents falling of the heel when lifting the shoe. Suitable profiles include, inter alia Dovetail, T and L profiles, the skilled person will recognize that a variety of different designs is possible.

According to embodiments of the invention, the fastening means is preferably designed so that a relative movement between the heel and the sole part is required for fastening the heel on the sole part, which has at least one direction component in the longitudinal direction of the sole. According to embodiments of the invention, the adjustment of the second stiffening element can thereby be effected.

According to a first variant, the fastening means is provided so that the heel can be pushed onto the sole part substantially in the longitudinal direction of the sole. The projections of the sole part and / or the grooves of the heel are preferably formed so that the heel along the sole longitudinal direction from behind to front on the sole member is pushed. For this purpose, the projection may extend, for example, substantially in the longitudinal direction of the sole. The projection preferably runs substantially parallel to the plane of the rear sole portion.

According to embodiments of the variant, the protrusion may have a tapered shape (in one or more views) and be substantially trapezoidal, for example. The projection may in this case be provided by the rear end region of the first stiffening element, but also by a separate component.

According to a second variant, the reinforcing means may be designed so that a load on the heel, for example a load on the heel along the (vertical) longitudinal axis of the leg when it arises and / or stands, leads to a reinforcement of the fastening. For this purpose, the projection of the fastening means is provided or formed so that it comes to a self-reinforcing positive locking when pushing the heel. The projection, in particular the profile of the projection, which is intended to engage in a recess of the shoulder, for this purpose preferably runs along a first imaginary straight line, which is an angle 89 °>Θ> 1 °, preferably 70 °>Θ> 20 ° , forms with the rear sole portion. The angle is preferably in a plane that is perpendicular to the plane of the rear sole portion and extends in the longitudinal direction paragraph. The profile of the projection therefore preferably extends in a direction which has at least one component in the longitudinal direction of the paragraph. Preferably, the profile runs along the rear sole portion in the longitudinal direction of the sole rear-to-front from the rear sole portion away. In a section transverse to the sole longitudinal direction, the profile is preferably wider than an overlying part of the projection which connects the profile with the rear sole portion.

According to embodiments of the second variant, the projection may have a substantially triangular or trapezoidal shape, wherein the distance between the lower edge of the projection and the rear sole portion increases preferably in the longitudinal direction of the sole.

The invention further relates to exchangeable heels which may be provided in combination with the above-described sole parts or as separate components. Thus, the sole part according to the invention can be provided with one or more exchangeable heels (eg as a set). Preferably, in each case a replaceable shoulder in the region of the rear sole portion can be pushed onto the sole part and fastened there.

In accordance with the first variant of the fastener, the paragraphs according to the invention may have a groove on their upper side. The groove preferably has a contour which is formed in correspondence with the profile of the projection. The profile and the groove are preferably formed so that they can engage in each other to prevent falling of the heel when lifting the shoe. The groove can run parallel to the top and in the longitudinal direction of the sole. In this case, it is preferably open at the front so as to allow the heel to be slid forward in the sole longitudinal direction onto the rear sole portion.

Corresponding to the second variant of the fastener, the exchangeable shoulders according to the invention can have a groove or a recess which extends into the shoulder from the top side of the heel along a second imaginary straight line. The second imaginary straight line preferably extends at an angle of 1 ° <η <89 °, preferably 20 ° <η <70 ° to the heel longitudinal direction, the straight preferably lying in a plane which is parallel to the heel longitudinal direction and sole longitudinal direction. The second imaginary straight line preferably coincides with the first imaginary straight line when the heel is mounted on the sole.

The recess preferably has a contour along the second imaginary straight line which is formed in correspondence with the profile of the fastening means. The profile Therefore, the fastener can preferably be pushed along the contour in the paragraph.

The contour is preferably formed so that the recess provides a plane that can interact with the profile to prevent the heel from falling down (eg, when lifting the shoe). The plane preferably extends in the sole longitudinal direction to the rear / top and is transverse and thus oblique to the longitudinal direction. The normal vector of the plane which points into the free space of the recess is therefore preferably directed in the longitudinal direction of the sole to the rear and in the longitudinal direction of the heel downwards. The normal vector is preferably perpendicular to the second imaginary line. In a cross-section transverse to the longitudinal direction of the hollow S the contour is preferably wider than the overlying part of the recess.

The recess preferably provides a stop against which the protrusion of the fastener may butt when the heel is fully pushed onto the rear sole area. The stopper is preferably provided in a front end portion of the recess. It may be a front wall at the end of the recess.

The recess is preferably in the interior of the paragraph and is open only at the top. The other outer surfaces of the shoulder are preferably not penetrated by the recess.

The heel is preferably pushed along the second imaginary straight line on the shoe. The projection of the fastener is therefore pressed under load of the paragraph in the direction of the degree of freedom (push-on) in the corresponding recess of the paragraph. Also in this case may be provided on the shoe and / or on the paragraph of a locking system, which, however, must absorb only small forces. The lock can therefore be realized for example not only mechanically but also by means of magnets. In addition, the paragraph has no side openings. This improves the appearance and prevents contamination of the recess.

As will be apparent to those skilled in the art, the fasteners described above may also be formed by corresponding protrusions on the shoulder and recesses in the sole portion. Therefore, the use of one or more protrusions on the heel that interact with one or more recesses in the sole portion in the manners described above is also considered as an alternative to or in combination with the above-described embodiments. According to embodiments of the invention, the heel is designed such that the attachment of the heel to the sole part results in adjustment of the first mechanism.

According to one embodiment of the invention, the shoulder at the top and / or at the front may have a recess or opening for receiving the first stiffening element. The recess is preferably elongated. The depth of the recess varies depending on the heel height, so that the rear part of the first stiffener is pressed more or less strongly against the rear sole portion when the heel is attached to the sole part.

According to a further disclosed embodiment, the paragraph may have a recess or opening which extends from the top and / or the front of the paragraph in the sole longitudinal direction to the rear and in paragraph longitudinal direction down in the paragraph and is open in the longitudinal direction of the sole forward. The opening is preferably provided so as to receive the rear part of the first stiffening element when the heel is attached to the sole part. The opening therefore preferably has an opening opening open to the front. Depending on the heel height, the recess or opening may extend at a different angle to the shoulder longitudinal axis.

The opening can taper from its inlet opening and become narrower, for example, in the insertion direction of the rear part of the first stiffening element (for example, become continuously narrower). For example, the opening may be designed such that it narrows and / or tapers in a first sectional plane which is parallel to the longitudinal direction of the heel and to the longitudinal direction of the sole. Alternatively or additionally, the opening may be designed such that it narrows and / or tapers in a second sectional plane, which is perpendicular to the first sectional plane and extends in the insertion direction of the rear part of the first stiffening element. In this case, the opening can essentially run in a straight line (for example at an angle of 2 ° to 70 °, 5 ° to 40 °, 5 ° to 15 ° or approximately 10 °), but alternatively or additionally, the opening can also have a number of different degrees of intensity have tapered and / or curved sections.

The opening preferably forms a substantially wedge-shaped structure with a surface of the heel top. The surface of the paragraph top, with which the wedge-shaped structure is formed, can bear against a first contact surface for the sole part when the heel is mounted on the sole part. The surface of the paragraph top, which forms the wedge-shaped structure with the opening, as the bottom of a U-shaped recess be provided, wherein the Ausnehmimg is preferably provided at the top of the paragraph.

The wedge-shaped structure is preferably provided or formed so that it is pushed forward when pushing the heel in the sole longitudinal direction between the first stiffening element and the rear sole portion. The tapered front end of the wedge-shaped structure is therefore preferably directed forward in the sole longitudinal direction substantially. The opening preferably receives the rear end of the first stiffening element. The embodiment therefore allows the first stiffening element to be pushed away from the rear sole part when the heel is pushed forward in the longitudinal direction of the sole on the sole part. Alternatively or additionally, the wedge-shaped structure can also interact with a projection or a rail of the first stiffening element.

The opening can be arranged at least partially in a protruding structure which protrudes from the upper side of the heel in the longitudinal direction of heel and / or in the longitudinal direction of the sole to the front. In this case, the above structure may have an upper slope (for example, an upper inclined surface), which at an angle ω of 20 ° to 70 °, 30 ° to 60 ° or 40 ° to 50 ° to the surface of the heel top, with the opening forms the wedge-shaped structure is arranged. The protruding structure may be arranged in the U-shaped recess, wherein the angle ω may be formed in this case between the upper slope and the bottom of the recess.

The above structure may provide an end abutment surface that is substantially parallel (eg, with a maximum deviation of ± 1 °, a maximum of ± 5 °, or a maximum of ± 10 °) to the surface of the heel top that forms the wedge-shaped structure with the opening, can be arranged. The upper slope and / or the end stop surface may be formed so that they come into contact with the sole part when fastening the heel on the sole part. The protruding structure may, according to embodiments of the invention, be formed in a top view of the heel substantially in the form of a T, wherein a protruding ridge, which preferably forms the leg of the T-shape, may extend rearwardly from the oblique surface in the longitudinal direction of the sole (for example for hooking a locking mechanism, which will be discussed in detail below). The bottom of the T-shaped structure may be completely disposed within the U-shaped recess. At the right and / or left tip of the T-shape, the above structure may be right and / or a left horn, which may protrude further than a central region of the T-shape. An end stop surface may be formed on each of the right and / or left horns. Between the horns, the projecting structure can be recessed and, for example, have a substantially rectangular recess.

According to a further embodiment of the invention, which is particularly advantageous when the heel is pushed rearwardly on the sole part in the longitudinal direction of the sole, the heel can have an opening which extends from the top of the heel in the longitudinal direction of the sole and in the longitudinal direction in the downwards Paragraph extends. The opening is preferably provided so that it receives the projection of the stiffening element when the heel is pushed onto the rear sole portion. Depending on the height of the heel, the opening may be steeper or flatter.

The opening preferably provides at least one surface which extends obliquely to the shoulder longitudinal direction. Preferably, the normal vector of the surface which points into the free space of the opening, in the longitudinal direction of the sole to the rear and in the longitudinal direction paragraph downwards.

In a sectional plane which runs through the opening parallel to the longitudinal direction of the sole and parallel to the longitudinal direction of the heel, the shoulder according to this embodiment preferably has a substantially wedge-shaped structure, wherein the tapering front end of the wedge-shaped structure is essentially in saw-off is directed to the rear.

The opening may be provided as part of a recess for the second fastener variant described above.

According to embodiments of the invention, the paragraph may also have a recess which is provided for receiving the depressed rear part of the stiffening element.

According to embodiments of the invention, the heel is designed such that the attachment of the heel to the shoe results in an adjustment of the second mechanism. For this purpose, the paragraph preferably has a recess which is provided or designed so that when intervening the heel with an element of the second mechanism intera giert or, depending on heel height, an interaction vennieden. Depending on the paragraph height, the recess may therefore also be designed so that the element of the second Mechanism in the recess fits and is not contacted when pushing the paragraph.

According to one embodiment, the recess has a contour which is provided or formed in such a way that it interacts with a gear of the second mechanism. Thus, for example, the recess may have a thread and / or a threaded sleeve for engagement with a thread of the second stiffening element, so that it comes with a displacement of the paragraph along the stiffening element to a rotation thereof (worm gear). If a displaceable threaded sleeve provided on the stiffening element, the recess may be designed so that it receives the threaded sleeve and moves it. Alternatively or additionally, the recess may have a contour in the form of a rack, which is provided or formed so that it comes to the rotation of a gear during the attachment of the heel on the shoe, which interacts with the stiffening element.

According to one embodiment of the invention, the recess has a contour which is provided or formed so that the lever of the second stiffening element can be adjusted when sliding the heel on the shoe. For example, the recess may take the form of a groove which narrows, twists and / or twists along the direction in which the heel is moved for attachment relative to the rear sole portion.

Thus, the recess may have, for example, one or more surfaces which extend along the fastening direction and are at least partially inclined to a plane which is spanned by the set from the longitudinal direction and the sole longitudinal direction. The surface is therefore in a section which is parallel to the paragraph longitudinal axis and is transverse to the sole longitudinal direction, obliquely to the longitudinal direction. Different angles preferably cause a certain rotation of the lever when pushing the heel. Preferably, a plurality of surfaces with different angles or a curved surface are provided so that the angle is successively changed. Alternatively or additionally, the depth of the recess in the longitudinal direction of the sole may decrease (for example to the rear), in which case the angle may remain substantially constant. The inclined surface may be formed by a side surface of the recess.

Alternatively or additionally, the groove may rotate (for example along the groove longitudinal direction and / or the sole longitudinal direction). In different cuts, in parallel extend to the paragraph longitudinal direction, the groove preferably assumes different angles to the paragraph longitudinal direction. For example, in a first cut, the groove may have a first angle to offset lengthwise and in a second cut a second angle to the heel length direction, the second angle preferably being greater than the first angle and the second cut preferably further from an entrance opening of the groove, through which the lever can enter the groove when the first cut is removed. In the region of the inlet opening, the groove can run substantially parallel to the longitudinal direction of the shoulder.

The recess is preferably open to the front and / or the top of the heel.

Optionally, the groove in the region of the inlet opening, through which the lever enters the groove, is wider and / or symmetrical with respect to the longitudinal direction of the shoulder, so that the shoulder can be pushed for different initial positions of the lever.

The recess may therefore be provided to interact with the lever in attaching the heel to the shoe to adjust the angle of rotation of the stiffener.

According to one embodiment of the invention, the heel is designed such that when it is fastened to the sole part, the angle between the rear sole portion and the middle sole portion is adjusted so as to provide a correct adjustment of the second stiffening member (eg, twist corresponding to heel height). is reached. This is particularly advantageous in connection with such embodiments in which the second stiffening element in the rear end region as described above has a second curved and / or angled segment which is movably received on and / or in the rear sole portion. The heel therefore leads by the setting of the first transition region simultaneously to a correct rotation of the second Versteifungsei ements.

The heel and / or sole portion may further include a locking system that locks the heel upon reaching a defined position. This is in particular a position that is achieved when the heel is completely pushed onto the rear sole portion. Depending on the design of the first and / or the second mechanism of the sole part and / or the attachment of the paragraph on the sole part, the locking system can be designed so that it is a movement of the assembled paragraph in Sole longitudinal direction counteracts to the rear, front and / or in paragraph longitudinal direction down.

To lock the paragraph may have on its upper side a locking element, which may be formed for example in the form of a projection, a hook and / or a latching lug. When fastening the heel on the sole part, the locking element preferably engages in a recess of the sole part, which is preferably provided on the rear sole portion. In the recess of the sole part, an undercut may be provided, in which engages the locking element. Alternatively or additionally, the sole portion (in particular the rear sole portion) may comprise a locking element (eg a projection, a hook, a ratchet and / or a latching lug) which fits into a recess of the heel (eg a recess on the Top of the paragraph) engages.

The locking element provides, in particular if it is designed as a hook, preferably an undercut for locking the heel on the sole part ready. The undercut can provide, for example, a recess open in the longitudinal direction of the sole or in the rear.

In addition, the locking element, in particular when it is formed as a hook, provide an inclined surface, which is preferably provided on the side of the locking element, which is facing away from the undercut and / or opposite. The inclined surface is therefore preferably located on the back of the hook when the undercut provides a forwardly open recess and disposed on the front when the recess is opened rearwardly. The inclined surface of the hook can be arranged at an angle γ of 90 ° to 150 °, 91 ° to 120 ° or 95 ° to 1 10 ° to the top of the heel. If a recess is provided at the top of the shoulder into which the sole portion (in particular the rear sole portion) is received, the angle γ between the base of the recess and the inclined surface may be formed.

The recess for receiving the locking element on the sole part may have a deflectable and / or movable latching element, which is deflected during insertion of the locking element and engages in the undercut of the locking element when the paragraph is completely pushed onto the sole part. The latching element is preferably provided by the locking element in the longitudinal direction of the sole pressed forwards or backwards when the heel is pushed onto the sole part. The latching element may for example be coupled to one or more springs (eg one or more coil springs) which are elastically deformed when the latching element is inserted into the receptacle. The latching element can be provided for example by a cylindrical or prism-shaped body, which is preferably hollow. So z. B. a hollow tube can be used. The locking element may be made of a different material than the rear sole portion, for example made of metal.

According to embodiments of the invention, the rear sole portion may provide first, second and / or third abutment surfaces for the heel (preferably for the top of the heel). Optionally, a fourth contact surface can additionally be provided. The first abutment surface is preferably adapted to abut the bottom of the recess at the top of the heel when the heel is mounted to the sole portion. The second contact surface is preferably arranged at an angle λ of 10 ° to 60 °, 20 ° to 40 ° or 25 ° to 35 ° to the first contact surface. It preferably connects to the first contact surface or is provided adjacent thereto. The third contact surface is preferably arranged substantially parallel to the first contact surface, but not in the same plane as the latter, wherein the third contact surface is preferably arranged adjacent to the second contact surface and / or connected via the second contact surface with the first contact surface. The fourth contact surface is preferably provided substantially parallel to the first contact surface. It is preferably not arranged in the same plane as the first contact surface, but closer to this than the third contact surface. The fourth contact surface may extend in a U-shape around the first, the second and / or the third contact surface. The heels according to the invention can accordingly be designed on their upper side so that they contact the first, second, third and / or fourth surface in the attached state. For example, the bottom of the recess at the top of the shoulder on the first contact surface, the top bevel on the second contact surface and / or the end stop surface on the third contact surface. The angle λ can be 180 ° less the angle ω.

The recess for receiving the locking element may have a wall which is arranged at an angle π to the first bearing surface. The angle π can be 60 ° to 140 °, 80 ° to 120 ° or 91 ° to 1 10 ° and preferably has a size of 180 ° minus the angle γ of the locking element (angle between the grand of Recess and the sloping surface). The wall can be a rear wall of the receptacle against which the inclined surface of the locking element abuts when the step is mounted on the sole part. The angle of the angles π and λ may be different.

The sole portion and / or the heel may further include a mechanism for releasing the locking system, for example when the heel is to be removed from the sole portion. The mechanism preferably allows an elastic deflection of the locking element and / or the locking element, so that the undercut of the locking element and the locking element can be decoupled and / or detached from each other.

The mechanism for releasing the locking system may, for example, have an actuator that provides an interface for the user. This actuating element may be, for example, a lever which is mechanically coupled to the latching element, so that the actuation of the lever leads to a deflection of the latching element. For example, the lever may be rotatably mounted on the sole part (eg on the middle sole portion). The locking element may be connected to the actuating element (eg the lever) via one or more cords (eg nylon cords) or wires. By the actuation of the actuating element (eg by the pivoting of the lever), a tensile force is preferably exerted on the cords, which leads to the deflection of the latching element. If the B etäti gun gsel ement is designed as a hollow body, a cord or a wire is preferably guided back from the actuating element by the hollow body and then back to the actuating element.

According to embodiments of the invention, the locking system can be reversed. The locking element (eg the hook, the ratchet or the latching lug) may, for example, be provided on the sole part (eg on the rear sole section) and the receptacle for the locking element may be formed on the shoulder.

The heel and / or the sole member may further provide a donning aid. By means of the tightening aid, the heel can preferably be held on the sole part and / or provided before the heel is locked by the locking system on the sole part. The dressing aid thus preferably allows a provisional attachment of the paragraph on the sole part. The heel is preferably held and / or provided by the tightening aid on the sole part in such a way that the heel is locked when the sole part (in particular the rear sole section) is subjected to weight. The heel can thus preferably be attached first to the dressing aid thanks to the tightening aid (eg with the aid of both hands), wherein the shoe with the sole part can then be placed on the ground and loaded (preferably without the heel falls) (eg B. by the weight of the wearer) to lock the paragraph using the locking system on the sole part.

The dressing aid according to the invention may be provided on the sole part by a cantilevered arm (which may also be referred to as a cantilever arm) which preferably extends rearwardly from the middle sole portion in the longitudinal direction of the sole and / or is provided below the rear sole portion. The arm preferably provides a detent or snap mechanism that secures the heel when the heel is put on the donning aid. For this purpose, the rear end region of the arm, for example, have a latching projection which engages in a corresponding recess of the paragraph. Alternatively or additionally, the arm may have a recess for a projection on the shoulder. It is also conceivable to provide the cantilever arm on the shoulder and a corresponding opening for the cantilever arm on the sole part.

The recess or the projection of the dressing aid on the shoulder is preferably provided in the interior of the paragraph, for example so that it / he is not visible from the outside. If the shoulder has an opening to receive the rear of the first stiffener when the heel is attached to the sole member (see above), the recess or projection may be provided in that opening, for example at the end of the opening furthest is removed from the inlet opening. The recess or the projection preferably form an undercut, in which the latching projection or the recess on the cantilevered arm can engage. The undercut can be provided, for example, at the (top) ceiling of the opening.

The cantilever arm is preferably designed so that it is elastically deflected when attaching the heel on the sole part and / or on the donning and snaps into this when reaching the undercut in paragraph. This will prevent inadvertent removal and / or falling off of the heel prior to final locking. Preferably, the cantilever arm when attaching the paragraph in Longitudinal direction deflected downwards. It can thereby be achieved that the arm pushes the heel after snapping into the hi nterschnei tion against the rear sole portion, which further complicates the accidental removal and / or falling of the heel.

The cantilevered arm may be coupled to the first stiffening element or formed by the first stiffening element according to embodiments of the invention. Preferably, however, the cantilevered arm is movable toward the rear end of the first stiffening element. If the first stiffening element is formed by two or more rails (see above), the cantilevered arm may be formed between and / or along two of these rails.

The sole portion and / or the heel may further comprise a mechanism for releasing the tightening aid. This is preferably designed so that it pushes the cantilever arm (in particular its locking projection and / or recess) from the undercut, which is provided on or in the paragraph, so that the paragraph of the sole part (in particular from the cantilever arm and / or from the rear end of the first stiffening element) can be deducted. The mechanism for releasing the tightening aid preferably allows an elastic deflection of the cantilever arm in the longitudinal direction downwards.

The mechanism for releasing the donning aid can be provided, for example, as a button or lever on the heel, by means of which the cantilevered arm can be pressed out of the undercut on the heel.

Alternatively or additionally, the mechanism for releasing the dressing aid may be formed on the sole part. In this case, the cantilever arm is preferably deflected via a knob or lever that the user can operate. For this purpose, for example, one or more rockers mounted around a first pivot lever may be arranged on the sole part. The first end of the / the lever can act on the cantilever arm, while the second end of the / lever serves as a user interface or is connected to a user interface. The first pivot point is preferably arranged between the first and the second end and / or in the middle sole portion.

The user interface can be designed as a lever or tab which can preferably be grasped at one end by hand and interacts with the rocker-like levers at its opposite end, with the rocker-type levers, and deflects the cantilevered arm over it. In this case, the user interface can be mounted at a second pivot point which is provided between its ends. If at one According to the invention, both a mechanism for releasing the locking system and a mechanism for releasing the tightening aid are provided, the actuating element of the mechanism for releasing the locking system and the user interface of the mechanism for releasing the tightening aid can be designed as a single element that fulfills both functions ( eg as a lever or button).

The rocker-type lever (s) may have a curved shape, wherein the first end may extend substantially along the rear end portion of the first stiffener and the second end may extend substantially along the middle sole portion. The first axis of rotation about the first pivot point and / or second axis of rotation about the second pivot point may extend substantially in the plane of the middle sole portion (in particular transversely to the sole longitudinal direction and / or transversely to the longitudinal direction of heel).

According to the invention, the first pivot point and / or the second pivot point can be provided by the first stiffening element, for example by the rocker-type lever (s) and / or the user interface being attached via pins to the first stiffening element. If the first stiffening element is formed by two or more rails (see above), the rocker-type lever (s) may be arranged between and / or along two of these rails.

The mechanism for releasing the dressing aid may be further configured to prevent re-snapping of the cantilevered arm with the undercut after release. For this purpose, the cantilever Ami can be locked, for example, in its deflected position. Alternatively or additionally, in the opening of the paragraph, in which the cantilevered Ami is introduced, a bevel may be provided, which leads to a displacement of the heel in the sole longitudinal direction when loosening the donning aid (ie preferably when deflecting the cantilevered Amis). As a result, the cantilever arm is preferably no longer engageable with the undercut of the heel, in particular, the opening in the heel may be configured to rearwardly displace the heel in the longitudinal direction of the sole by deflecting the cantilevered arm downwardly. The cantilever arm is then after loosening the dressing preferably on the upper ceiling of the opening in the paragraph, without being able to re-engage with the undercut can. If the mechanism for releasing the dressing aid deflects the cantilever arm upwards (for example because the Hinterschnei tion at the grand of the opening is provided), the cantilever arm can then rest against the ceiling of the opening, without being able to re-engage with the undercut can. Preferably, the paragraph can then be deducted from the sole part, for example, in the sole longitudinal direction to the rear. The slope can be arranged, for example, at an angle of 5 ° to 85 °, 20 ° to 70 ° or 30 ° to 60 ° to the paragraph longitudinal direction (depending on the embodiment in a clockwise or counterclockwise direction).

According to embodiments, the invention relates to a set of heels of different heights, wherein the heels of different heights are designed so that their attachment to the shoes described above lead to different adjustments of the first and / or the second mechanism.

According to embodiments of the invention, the sole part according to the invention can have one or more of the mechanisms described above for adjusting the curvature in the first transition region and / or one or more of the mechanisms described above for adjusting the sole curvature in the second transition region. If no mechanism is provided in one of the transitional surfaces, the sole part in this transition region can, for example, be made so flexible that it deforms due to the weight of the wearer or wearer.

The invention further relates to shoes with one of the described sole parts and / or one of the paragraphs described.

The described mechanisms, sole parts and heels can each be provided individually or in any combinations and sets.

The rear sole portion, the middle sole portion, and / or the front sole portion may be made of polyamide (eg, PA12). For the production (also for serial production) of the rear sole portion, the middle sole portion and / or the front sole portion, for example, rapid prototyping can be used.

As shown in FIGS. 1A and 1B, when using heels of different heights (flat heel in FIG. 1A, "high", block-represented heel in FIG. 1B), the bow should be approximately in a first range A the heel and the foot bridge portion of the sole, and in a second region B, which is located approximately between the Fußbrücken- and the Vorderfußabschnitt the sole, are adjusted.

Figure I C shows schematically sole parts 3 with a rear sole portion 4 (heel portion), a middle sole portion 5 (midfoot portion) and a front sole portion 6 (forefoot portion). The superposition of a first sole mold 11, which corresponds to that of a flat shoe, and a second sole mold 12, which corresponds to that of a shoe with a high heel, shows that the sole curve in the first region A and in the second region B when using a higher heel should be larger (sole mold 12). The angles α <180 ° between the rear sole portion 4 and the middle sole portion 5 and β <180 ° between the middle sole portion 5 and the front sole portion 6 are preferably smaller for the sole shape 12.

The shoes and sole parts according to the invention can be used with a variety of different heel fastening systems. FIGS. 2A-2D and 3A-3D show systems which have proved to be particularly advantageous in the context of the present invention. Figures 2A and 2B show a sole member with a fastener 20 for attaching exchangeable heels. The fastener 20 is provided on the rear sole portion 4 and preferably has one or more projections 21 having a profile 22. The projections 21 and / or the profile 22 preferably run parallel to the plane E of the rear sole portion and in the sole longitudinal direction.

Figures 2C and 2D show a first type of exchangeable paragraphs. The shoulder 30 preferably has at its upper side 35 a groove 32 which has a contour which is formed in correspondence with the profile 22 of the rear sole portion 4. The profile 22 and the groove 32 are therefore formed so that they interlock and a fall of the heel during lifting of the shoe is prevented. For this purpose, the profile is preferably wider than an overlying part of the projection (undercut). The profile 22 or the contour of the groove may for example have a dovetail, T or L shape. The projection 21 is shown in Figures 2A and 2B for illustrative purposes only with an L-profile 22.

The groove 32 extends parallel to the top 35 and in the sole longitudinal direction. It is open at the front to allow the heel 30 to be pushed onto the rear sole section 4 in the direction of the arrow D (forward in the longitudinal direction of the sole). The heel and / or shoe may further include a locking system (not shown) that locks the heel upon reaching a defined position. The locking system preferably counteracts a movement of the mounted paragraph to the rear. Different locking systems are described in more detail below.

FIGS. 3A and 3B show a sole part with a fastening means 20 'according to a further embodiment of the invention. The fastening means 20 'is provided on the rear sole portion 4 and has a projection 21' with a profile 22 'which preferably extends along the lower end of the projection 21'.

The profile 22 'extends obliquely to the plane E of the rear sole portion 4 and preferably away from the plane E and down. When the rear sole portion 4 is viewed from the side (see FIG. 3B), the profile 22 'preferably extends along a first imaginary line or straight line G forming an angle of 70 °>Θ> 20 ° with the plane of the rear sole portion E. , The angle is preferably in a plane that is perpendicular to the plane E of the rear sole portion 4 and extends in the longitudinal direction of the sole. As further shown in Figures 3A and 3B, the projection 2Γ may have a substantially trapezoidal shape. FIGS. 3C and 3D illustrate a replaceable shoulder 30 'for the fastener 20' of FIGS. 3A and 3B. The shoulders have a recess 31 'extending from an elongate opening 34' on the top 35 'of the heel 30' in FIG extends the paragraph into it.

The recess 3 Γ preferably has along a second imaginary line or straight line H a substantially constant contour 32 ', which is formed in correspondence with the profile 22' of the fastening means 20 '. The contour 32 'extends along the second imaginary straight line H, which preferably extends at an angle of 20 ° <η <70 ° to the shoulder longitudinal axis F, when the shoulder 30' is viewed from the side (see FIG. 3D). As can be seen in FIG. 3D, the straight line H is preferably located in a plane which is parallel to the shoulder longitudinal axis and to the longitudinal axis. The straight lines G and I I preferably coincide when the shoulder 30 'is mounted on the rear sole portion 4. The shoulder 30 'can therefore be pushed along the straight line G or H in the sole longitudinal direction to the rear (direction K) on the fastening means 20'.

As further shown in Figures 3C and D, the contour 32 'is preferably configured so that the recess 3Γ provides a plane that interacts with the profile 22' to allow the heel to descend downward (eg, when lifting of the shoe). The plane therefore preferably points downwards in the longitudinal direction of the sole and downwards in the longitudinal direction of the heel, the normal vector of the plane pointing into the free space of the recess being directed in the longitudinal direction of the sole to the rear and in the longitudinal direction of the heel. If the recess is viewed in a section which runs parallel to the shoulder longitudinal axis F and transversely to the sole longitudinal direction, the contour 32 'is preferably wider than an overlying region of the recess 31'.

The recess 3 Γ is preferably in the interior of the paragraph 30 'and is only open to the top 35'. When sliding the heel 30 'onto the rear sole portion 4, the recess 3 Γ in its front end region (eg on a front wall) preferably provides a stop 33' to which the projection of the fastening means 2Γ can butt when the heel pushed completely onto the back sole area. The subsequent loading of the rear sole portion 4 in the longitudinal direction F of the heel downwards (eg due to the weight of the wearer or wearer) therefore results in a self-reinforcing positive fit.

The rear sole portion 4 and / or the heel may further comprise a lock, which may be, for example, mechanical or magnetic. So can the rear Sole section 4, for example, have a projection which is provided or formed so that it engages in a recess in the top 35 'of the paragraph 30' or adjacent to the front of the paragraph when the shoulder 30 'is completely pushed. Alternatively or additionally, a projection on the upper side 35 'may be provided or formed so that it engages in a recess which is formed on the underside of the rear sole portion 4.

FIGS. 4A to 4C schematically illustrate a first embodiment of the first mechanism 100 for adjusting the sole curve in the first transition region A of a sole part 3.

The mechanism 100 has a stiffening element 14. This is stiffer than the first transition region A, wherein the flexibility of the sole member may result, for example, from the properties of the materials used or due to the use of a hinge in the first transition region. The sole part may have a first joint in the first transition region A and a second joint in the second transition region B. The first joint may extend along the first transition region A and the second joint along the second transition region B.

The stiffening element 14 extends along the rear sole section 4 and the middle sole section 5. Along the middle sole section 5, the stiffening element 14 is at least partially firmly connected to the sole part 3. The stiffening element 1 14 may have a substantially flat, elongated structure in this area.

A rear portion 115 of the stiffening member 114 extends along the rear sole portion 4, but is not connected or fixed to the rear sole portion 4. The distance between the rear sole portion 4 and the rear portion 15, in particular the angle therebetween, can therefore be varied, as shown in Figures 4A-4C. This leads to the adjustment of the angle δ between the middle and the rear sole portion and thus to adjust the sole curvature in the first transition region A. As shown in Figure 4A, the curvature in the first transition region A is smaller when the angle between the rear part 1 15th and the rear sole portion 4 increases. If the angle is smaller, the sole curvature increases (FIG. 4B). The sole curvature in the first transition region A is therefore smaller when the rear part 1 15 of the first stiffening element 1 14 is further spaced from the rear sole portion 4. If the rear part 1 15 pressed closer to the sole part 4, the curvature increases against it. The curvature in the first transition region A can therefore be changed according to the heel height, with a continuous adjustment is possible. Depending on the imple mentation of the invention, the rear part 1 15 of the stiffening element 1 14 may rest in a neutral state of the first mechanism on the rear sole portion 4 or be spaced therefrom.

Depending on the embodiment, the heels according to the invention may be designed in such a way that when the heel is fastened, the stiffening element 14 is pressed against or pushed away from the rear sole section. According to one embodiment, which is shown in FIGS. 5A and 5B cut laterally and along the longitudinal direction of the sole, the shoulder 30 "has a structure 41" for pushing the stiffening element 14 away from the underside of the rear sole portion. The structure 41 "is preferably formed by an opening 43" which extends from the top 35 "in the longitudinal direction of the sole back and in paragraph longitudinal direction F down in the paragraph 30" and is open in the longitudinal direction of the sole forward. The opening 43 "receives the rear part 15 of the stiffening element 14 when the shoulder 30" is pushed onto the rear sole section 4. The opening 43 "therefore preferably forms a structure 41" in a wedge shape, wherein the tapered end of the wedge-shaped structure is directed forward in the longitudinal direction of the sole. Depending on the height of the heel, the opening 43 "can be steeper (FIG. 5A) or less steep (FIG. 5B), and consequently cause a larger or smaller angle .delta. (See FIGS. 4A-4C) when the heel 30" is fastened to the sole part 3. ,

The shoulder 30 "may also be configured for use with any of the attachment systems 20, 20 'described above, particularly for use with the attachment system 20. The shoulder 30" may therefore include, for example, one or more of the grooves 32 described above.

According to a variant, the paragraphs of Figures 5A and 5B (ie, both high and low or medium heels) may be designed so that the opening 43 "tapers or becomes progressively narrower in the direction of insertion of the rear part 115. Such a variant is exemplified in Figs 5E (perspective view), FIG. 5F (first sectional plane parallel to the longitudinal direction of descent F and to the sole longitudinal direction L) and FIG. 5G (second sectional plane transverse to the first sectional plane and parallel to the insertion direction E) of the shoulder 30 " shown. As shown in particular in FIG. 5F, the shoulder 30 "may have an opening 43" which, in a first sectional plane parallel to the longitudinal direction F of the inlet opening 44 ", through which the rear part 1 15 of the stiffening element (not shown) into the opening 43". can be inserted, according to an angle κ in the direction of insertion E tapers. Likewise, the opening 43 "can be designed so that it tapers in a second cutting plane, which is transverse to the first cutting plane and parallel to the insertion direction E (see Figure 5G), of the inlet opening 44" in the direction of insertion E corresponding to an angle ε. In this case, the angle κ and / or ε in each case 2 ° to 70 °, preferably 5 ° to 40 °, more preferably 5 ° to 15 ° or about 10 °. In order to ensure a play-free attachment of the shoulder 30 "in several directions, the opening 43" may be designed tapering in several sectional planes, for example in section along the paragraph longitudinal direction F (Figure 5F) and in section along the insertion direction E (see Figure 5G). As can also be seen in FIGS. 5E to 5G, the opening 43 "for the rear part 11 of the stiffening element 14, which forms the wedge-shaped structure 41" with the upper side 35 "of the shoulder 30" (see FIG. 5F), can at least may be partially disposed in a protruding structure projecting from the top surface 35 ". The projecting structure 45" may here comprise an upper slope 48A "having an angle ω of 20 ° to 70 °, 30 ° to 60 ° or 40 ° to 50 ° with the top 35 "can form. Further, the protruding structure 45 "may have a phased or inclined end stop surface 48B" that may extend substantially parallel (eg, at a maximum deviation of ± 1 °, ± 3 °, or ± 5 °) from the top 35 ". The upper slope 48A "and / or the end stop surface 48B" may be formed to contact the sole portion when the heel 30 "is secured to the sole portion. A protruding structure 45 "according to Figures 5E and 5F may be used in combination with a tapered opening 43", but also independently.

FIGS. 5H and 5J show a variant of the first stiffening element 14 on a sole part 3 shown diagrammatically. The variant can be used with different heels according to the present invention, in connection with the paragraph variants of FIGS. 5E to 5G and I IA to 12C (FIG. see below) but special advantages.

In the variant of the first stiffening element 14 according to FIGS. 5H and 5J, the stiffening element 114 is formed by two rails 114A and 14B, although only one rail or more than two rails can be used. The rails 1 14A, 1 14B extend along the middle sole portion 5, the sole not being shown in the middle sole portion 5 for better illustration of the rails 14A and 14B. The rails 1 14A and 1 14B may be made of a flat steel, for example.

The rails 1 14A and 1 14B provide a first hinge 601, via which the rear sole portion 4 is movably attached thereto, and a second hinge 602, via which the front sole portion 6 is movably attached thereto. For this purpose, the rails 1 14A and 1 14B may each have a first bore for receiving an axis of the first joint 601 and a second bore for receiving an axis of the second joint 602.

The rails 1 14A and 1 14B are arranged in the illustrated embodiment, substantially parallel or slightly tapered. For use at the heels of Figures 5E to 5G and Figures 1A to 12C, the rear portions 15A and 15B of the rails 14A and 14B may converge rearward in the longitudinal direction of the sole (e.g., at angle e). The stiffening element 1 14, which is formed jointly by both rails 1 14 A and 1 14 B, therefore becomes narrower. Moreover, as can also be seen in FIG. 5H, the rear part 1 15A and 1 1 5B (only the rear part 1 15A is visible in FIG. 5H, but the rear part 1 15B can be mirror-inverted) of each stiffening element 1 can also be seen 14A, 14B themselves become narrower (eg at the angle κ). Together with the tapered opening 43 "can thus be achieved in spite of any manufacturing tolerances a substantially backlash-free attachment of different heels on the sole part 3.

As shown in Figures 6A and 6B, the first stiffening element 1 14 'according to a second embodiment of the invention in the region of its rear part 1 15' has a projection 1 17 '. The projection 1 1 7 'extends in the example shown down from the stiffening element 1 14' away and provides a surface 1 19 ', which extends substantially in the transverse direction of the sole member 3 and extends obliquely to the plane of the rear sole portion 4. The surface 1 19 'preferably forms an angle of 70 °>Θ> 20 ° with the plane of the rear sole portion E, wherein the angle is preferably in a plane which is perpendicular to the plane E of the rear sole portion 4 and extends in the sole longitudinal direction. The normal vector M of the surface 1 19 ', which points away from the projection 17', preferably points upwards in the longitudinal direction of the sole and upwards in the longitudinal direction of the heel. According to embodiments of the invention, the projection 1 17 'corresponds to the projection 2Γ of the fastening means 20' described above with reference to FIGS. 3A and 3B. The surface 119 'may be formed by a profile 122', which corresponds to the profile 22 'of the fastener 20' and is also shaped. The fastening means 20 'can therefore be provided on the stiffening element 1 14', wherein the projection 1 17 'at the same time for adjusting the first mechanism 100 and for attaching the heel on the shoe is used.

Alternatively, the projection 117 'may also be provided in combination with an additional attachment means, for example the attachment means 20' of Figs. 3A and 3B. The additional fastening means may be provided, for example, on the rear sole part 4.

The middle sole portion 4 may have a recess 8 for receiving the rear part of the stiffening element 114 '.

The stiffening element 1 14 'is shown in FIGS. 6A and 6B as being integral with the middle sole section 5. However, also in this embodiment of the invention, various elements and materials may be used for the stiffening element 14 'and the middle sole portion 5 (see Figures 4A-4C).

Figures 7A-7H show another type of exchangeable paragraphs according to embodiments of the invention. These are particularly advantageous when used with the stiffening element 1 14 'of Figures 6A and 6B.

The paragraphs 30 "'of Figures 7A-7H have a recess 3 Γ" for the projection 1 17' of the stiffening element 1 14 '. The recess 3 Γ "may have the features of the recess 3 Γ, which is described above with respect to the paragraphs 30 '.

Shown cut along the sole longitudinal direction (see FIG. 1C), the shoulders 30 '' 'have a structure 46' 'for pushing the stiffening element 14' from the underside of the rear sole portion. The structure 46 "'is preferably formed by an opening 47"' extending from the top 35 "'in the longitudinal direction of the sole forward and in paragraph longitudinal direction F down in the paragraph 30"'. The opening 47 "'is preferably provided so that it receives the profile 122' of the stiffening element 1 34 'when the shoulder 30"' is pushed onto the rear sole portion.

The structure 46 '' is preferably wedge-shaped with the tapered end of the wedge-shaped structure facing rearward in longitudinal direction Paragraph may be the opening 47 '' steeper (Figures 7A-7D) or flatter (Figures 7E-7H) run.

In other words, the shoulders 30 '' ', when shown cut along the sole longitudinal direction, have at least one surface 49' 'formed by the opening 47' '' The surface 49 '' extends obliquely to the heel longitudinal direction F ' the normal vector O of the surface 49 '", which points into the free space of the opening 47' ', points in the longitudinal direction in the longitudinal direction in the longitudinal direction and in the longitudinal direction of the paragraph.

As a comparison of the sections of FIGS. 7C and 7D and of FIGS. 7G and 7H shows, the recess 31 '"has a contour that is wider in a lower area than in an upper area.

The heels 30 "'may, depending on the height further have a recess 37"', which is provided for receiving the depressed rear portion of the stiffening element 1 14 '(see Figures 7E and 7G).

In addition to one or more recesses 3 "for the projection 17 'of the stiffening element 14', the shoulders 30" 'may also have one or more recesses 3 "for an additional fastening means (eg a fastening means 20') for example, can be provided directly on the rear sole portion.

8A and 8B show a sole part 3 with a high or a flat shoulder 30 "', depending on the course of the opening 47"' or the shape of the wedge-shaped structure 46 '', the rear part 1 15 'of the reinforcing element continues or less far from the rear sole portion 4. As shown in Fig. 8B, the stiffening member can be received in the recess 37 "'of the heel.

Regardless of the embodiment of the first mechanism, the sole parts and / or heels according to the invention can be provided with a locking system for locking different heels on the sole part. For this purpose, a projection is preferably provided on the heel or on the sole part, with a recess or recess being provided on the other of these two elements (i.e.

A first embodiment of a locking system 500 according to the invention is shown schematically in Figures 5C and 5D (in conjunction with a first mechanism according to the first embodiment) and Figures 9A, 9B, 10A and 10B (in conjunction with a first mechanism according to the second embodiment). As in FIGS. 5C and 513 it can be seen, the locking system 500 is provided via a recess 501 on the rear sole portion 4, which is provided so that a projection 502 engages the shoulder in the recess 501 when the heel is completely pushed onto the sole member. Figures 9A, 9B, 10A and 10B show that the arrangement of the recess 501 and the projection 502 can also be reversed so that the recess 501 is provided on the heel and the projection 502 on the sole part. The locking of the locking system 500 can be solved in both cases by the rear sole portion 4 is raised. This embodiment is therefore particularly advantageous if the heel is pressed down by the fastening means or by the first stiffener to the rear sole portion.

Figures 1 1A, 1B and 12A to 12C show paragraphs with a locking system 500 'according to a second embodiment. The shoulder 30 "has on its upper side 35" a recess in which a locking element in the form of a protruding hook 502 'is arranged. The hook 502 'hereby provides an undercut which forms a recess 506', which is open in the longitudinal direction L of the sole longitudinally. On the back of the recess 506 'opposite the hook 502' has an inclined surface 504 ', which in a. The angle γ may hereby differ from the angle ω between the inclined surface 48A "of the projecting structure 45" and the upper side The angle γ may be approximately 90 ° to 150 °, about 91 ° to 120 ° or about 95 ° to 1 10 °.

13A to 13C show a rear sole part 4 with a recess 50Γ for receiving the hook 502 'of the shoulders 30 "of FIGS.1A to 12C.The recess 50Γ has a deflectable detent element 52Γ (eg in the form of a hollow tube). which, upon insertion of the hook 502 'against the force of the springs 523' deflects in S ohl enlängsri rect direction forward and into the recess 506 'of the hook 502' engages when the paragraph 30 "is fully pushed onto the sole member. As a result, the paragraph 30 "is locked on the rear sole member 4.

As can also be seen with reference to FIGS. 13A to 13C, a first abutment surface 51 ', a second abutment surface 512' and a third abutment surface 513 'for the shoulder can be provided on the rear sole section 4. While the first abutment surface is adapted to abut the bottom of the recess at the top 35 "of the shoulder 30" when the shoulder 30 "is mounted to the sole portion, the second abutment surface 512 ' preferably arranged at an angle λ to the first bearing surface 51 Γ and thus provides a contact surface for the upper inclined 48 A "of the paragraph 30". The angle λ can therefore have an angular extent of 180 ° minus the angle ω between the upper side 35 "and the upper slope 48A". The third abutment surface 513 'may provide a abutment surface for the end stop 48B ", rubber stoppers may be disposed on this third abutment surface 513' or other abutment surfaces to compensate for manufacturing tolerances between different shoulders." The third abutment surface 513 'may be substantially parallel to the first abutment surface ,

The recess 50 Γ may further comprise a wall 507 ', which is arranged at an angle π to the first bearing surface 51 Γ and provides a bearing surface for the inclined surface 504' of the hook 502 '. The angle π may therefore have an angular extent of 1 80 ° minus the angle / between the top 35 "and the sloping surface 504 'of the hook 502' can be achieved over the inclined surface 504 'of the hook 502' on the wall 507 ', a substantially play-free connection between the shoulder 30 "and the rear sole portion 4 can be achieved. For this purpose, the measure of the angle / and π is preferably different.

At the rear sole part 4, a contact surface 514 'can also be provided. This can run substantially parallel to the first contact surface 51 Γ, but is preferably not arranged in the same plane as this. The fourth contact surface 514 'may extend in a U-shape around the first contact surface 51', the second contact surface 512 'and / or the third contact surface 513'.

As illustrated in the schematic sequence of Figures 14A-14C, to arrest the heel 30 "at the back sole portion 4, the back portion 15 of the first stiffener is first inserted into the opening 43" of the heel 30 "(Figure 14A) 4 is then pivoted to insert the hook 502 'into the recess 50Γ, which deflects the detent element 52Γ against the force of the springs 523' (Figure 14B) Upon reaching the end position of the shoulder 30 "at the sole portion (Figure 14C) snaps the locking element 52 Γ then into the recess 506 ', whereby the paragraph 30 "is locked.

Figure 15 shows an inventive mechanism 530 'for releasing the locking of a heel (not shown) from the sole part (only partially shown). The mechanism is shown here for better illustration in connection with the locking system of Figures 1 1A to 14C, but is not limited thereto.

Via the mechanism 530 ', the latching element 52 can be deflected against the force of the springs 523' until the latching element 52 is moved out of the recess 506 '(see FIGS. 14A to 14C). The engagement between the hook 502 'and the locking element 52 Γ is thereby released so that the heel can be removed from the sole part.

The mechanism 530 'has an actuator 53 Γ that can be grasped by the user and thus provides an interface for this. In the exemplary embodiment of Figure 15, the actuator 53 Γ is designed as a lever. This is rotatably mounted on the sole part, for example, on the first stiffening element 1 14. For this purpose, the lever may for example be arranged between two rails 1 14A and 1 14B, which form the stiffening element 1 14. Mechanism 530 'is not limited to this.

The actuating element 53 Γ is mechanically coupled to the latching element 52 Γ. This is accomplished in the exemplary embodiment of Figure 15 by means of a lance or wire 535 '(e.g., a plastic cord, such as a nylon cord) extending from the actuator 53Γ to the latch member 52Γ and back again. By the actuation of the actuating element 53 Γ a tensile force is exerted, which is transmitted from the cord to the locking element 52 Γ and this deflects.

Referring again to Figures 12A-12C, it will be appreciated that the protruding structure 45 "of the shoulder 30" in a plan view of the top surface 35 "takes substantially the shape of a T, with a ridge 48C" extending from the base surface from the sloping surface 48A "to the hook 502." A portion 48D "between the left and right tips of the T-shaped structure may be recessed, with the right and left Leaves a horn at a time that the upper slope 48A "and the end stop surface 48B" can provide. In this case, the T-shaped structure can be arranged completely within the recess on the upper side 35 ", as is also shown in the exemplary embodiment of FIGS. 12A to 12C.

FIGS. 16A and 16B show a first embodiment of a second mechanism 300 for adjusting the second transition region B between the middle sole portion 5 and the front sole portion 6. Mechanism 300 includes a slidable stiffener 302 that can be translated along the sole longitudinal direction from a first position (FIG. 16A) that causes a first sole curve in transition region B to a second position (FIG. 16B) that has a second sole curvature effected in the transition region B. In this case, the first sole curve differs from the second sole curve.

The sole part 3 is preferably made more flexible than the stiffening element 302 in the transition region B. For example, the transition region B can be provided with a joint (see, for example, FIGS. 5H and 5J) and / or designed to be more flexible than the rear, the middle and / or the front sole section 4, 5, 6.

In the first position (FIG. 16A), the stiffening element 302 preferably does not project into the transition area 13 and / or into the front sole section 6. The sole curve in the transition area B therefore corresponds to the curvature with which the sole part 3 was manufactured.

If the stiffening element is pushed into the second position (FIG. 16B), it protrudes into the second transition area B and into the front sole section 6. Since the stiffening element is guided along the transition region B and / or in the front sole section 6 (eg in an opening in the front sole section 6, which is not shown for reasons of clarity), the transitional region B or the front sole section 6 follows in FIG In this case, the shape of the stiffening element 302. The displacement of the stiffening element 302 thus leads to a change in the sole curvature in the transition region B.

As further shown in FIGS. 16A and 16B, the stiffening element 302 is preferably also guided in the region of the middle sole section in a guide 306. This is formed in the example shown as a rail. The guide 306 retains the stiffener 302 at the middle sole portion 5 as the stiffener 302 advances and extends into the transition region B. Thus, buckling or bending of the stiffening element 302 along the middle sole portion is prevented.

The second mechanism also has, according to the illustrated embodiment of the invention, a Bowden cable 310 with a Bowden cable core 312 and a Bowden cable housing 314. The Bowden cable core 312 extends from the rear sole portion 4 to the stiffening element 302 and is firmly connected thereto. A displacement of the Bowden cable core 312 therefore leads to a displacement of the stiffening element 302. Thus For example, the stiffening element 302 can be displaced between the first and the second position by actuation of the transmission element (Bowden cable core 312).

The transfer member is preferably actuated upon placement and / or removal of the heel. For this purpose, a driver 316 is provided at the rear end of the Bowden cable core 312, which interacts with exchangeable heels to allow an adjustment of the movement device when placing and / or removing the heel. The driver 316 is fixedly connected to the Bowden cable core 312.

The bowden sheath 314 may be secured to the sole portion 3 and / or to the first stiffener 114, whereby the bowden cable may extend through the recess of the first stiffener (see FIGS. 16A and 16B).

The second mechanism according to FIGS. 16A and 16B can be used with different first stiffening elements 1 14, 1 14 '.

As shown in FIGS. 17A and 17B, the shoulders 330, 330 'according to the invention may have, at their upper side 335, 335', a recess 360, 360 ', which is provided so as to engage with the attachment of the heel to the sole part an element of the second mechanism according to the embodiment of Figures 16A and 16B interacts or avoids an interaction. Thus, the shoulder 330 of Figure 17A has an elongated recess 360 which is designed so that there is no displacement of the driver 316 when pushing and pulling the shoulder 330 on the rear sole portion 4. The recess is therefore designed so that the driver 316 is not contacted. The longer dimension of the recess 360 preferably extends in the longitudinal direction of the sole, wherein the recess may extend approximately 20 to 30 mm in this direction (length of the recess).

On the other hand, in paragraph 330 'of Fig. 17B, the recess 360' is shorter (e.g., at most 5 mm or more than 10 mm long) and is approximately in the shape of the follower 316. The follower 316 will slide on the heel 306 'in the Recess 360 'recorded and moved with the shoulder 306', which results in an adjustment of the mechanism 300. In the exemplary embodiment of FIG. 17B, the recess 360 'is configured to move the follower forward as the heel 330' is slid from back to front onto the rear sole portion 4. The shape of the sole portion of Fig. 16A therefore changes to that of Fig. 16B. Figures 18A-19C show another second mechanism 400 for adjusting the second transitional region B according to another embodiment of the invention in various side and rear positions.

The mechanism 400 has a rotatable stiffening element 402, which in the illustrated example is designed as an elongated shaft. The stiffening element 402 extends from the middle sole section 5 into the transition region B and preferably also into the front sole section 6 and / or the rear sole section 4.

In the front end region, the second stiffening element 402 has a curved segment 403, which has a predetermined, defined curvature and extends at least in the transition region B. To the curved segment 403 may connect a front end segment 404 of the stiffening element 402. This is preferably received in the region of the front sole portion 6 in a recess 407 which allows movement of the end segment 404 in the plane of the front sole portion 6.

The stiffening element 402 is rotatably mounted in the region of the middle sole portion 5 and / or of the rear sole portion 4. When the stiffening element 402 is rotated from a first angle of rotation (FIGS. 18A and 19A) to a second angle of rotation (FIGS. 18B, 19B and 19C), the front end segment 404 pivots in the recess 407. The projection of the curved segment 403 onto a projection plane extending along the axis of rotation of the stiffening element 402 and is perpendicular to the plane of the front sole portion 6, therefore, changes its curvature and is preferably larger when the stiffening element 402 is rotated from the first to the second position. The second sole curvature is larger than the first in this case.

The curved portion 403 of the stiffening element 402 preferably tensions a mental curvature plane, in which the radius of curvature also lies. This plane of curvature may be perpendicular to the plane of the front sole portion 6 when the stiffener 402 is twisted to the second angle of rotation (see Figure 19C).

The rotation of the stiffening element 402 further causes the front end segment 404 to protrude into the recess 407 to different degrees.

The stiffening element 402 may further comprise a lever 416, over which the stiffening element 402 is twisted. The lever 416 is preferably provided in the region of the rear sole portion 4. FIGS. 19A-19C show the sole part 3 from the rear, wherein the reinforcing element 402 is shown at different angles of rotation. Due to the pivoting of the curved region 402, these cause different sole curvatures in the transition region B.

FIGS. 20A and 20B show, by way of example, various possibilities for the rotatable mounting of the stiffening element 402. Thus, the stiffening element 402 may be located in a recess of the sole part (FIG. 20A) or in a conventional manner, for example the sleeves (eg brass tubes) of FIG. which are preferably firmly connected to the sole part 3 (eg by gluing, welding, soldering, etc.), are stored. In combination with the lever 416 or other protrusions of the stiffening element 402, the holding device can also prevent an axial displacement of the second stiffening element in the longitudinal direction of the sole.

As further shown in Figure 21, the lever 416 and / or the curved segment 403 can be formed by sliding a sleeve (eg, a brass tube) over the rear end portion of the second stiffener 402 and bending it along with it.

Figures 22A-22D show paragraphs of different heights 330, 330 ', 330 "having a recess 360, 360', 360" which interacts with the lever 416 of the stiffening member 402 of the second mechanism of Figures 18A-19C. The contour of the recess 360, 360 ', 360 "is in particular provided so that the recess in the attachment of the paragraph 330, 330', 330" interacts with the lever 416 on the sole part 3.

To adjust the lever 416, the recess 360, 360 "according to one embodiment, a surface 361, 361", which is in a section of the paragraph, which is parallel to the paragraph longitudinal axis and transverse to the sole longitudinal direction, obliquely to the set longitudinal direction F (Figure 22D ). The surface 361, 361 "contacts the lever 416 when the heel is pushed onto the sole member so that the lever 416 is rotated in accordance with the slope of the surface 361, 361". In the embodiment shown, the angle formed by the sloping surface 361, 361 "with the upper surface 335, 335" of the shoulder 330, 330 "preferably becomes flatter in the longitudinal direction of the sole, so that the lever 416 is successively twisted until a desired end position is reached ,

According to another embodiment shown in Figures 23A-23F, recess or groove 360, 360 ', 360 "may twist along the sole or groove longitudinal direction, depending on the heel height, the groove may be twisted differently so that it slides when pushed of the heel comes to the rear sole portion 4 for the desired rotation of the lever (see Figures 23A, 23B and 23C, wherein in each case the achieved rotation of the lever is shown).

In this case, the groove 360, 360 "preferably twists successively in the sole longitudinal direction and assumes different angles to the shoulder longitudinal axis in different sections running parallel to the longitudinal direction of the shoulder, for example, the groove 360 extends in the region of an inlet opening through which the lever 416 extends into the groove can enter, substantially parallel to the paragraph longitudinal direction F (see Figure 23D), in a first section which is parallel to the paragraph longitudinal direction F, at an angle (pi the paragraph longitudinal direction F (see Figure 23E) and in a second section, which is also parallel to Paragraph longitudinal direction F, but farther away from the entrance opening of the groove 360 than the first cut, is at an angle φ 2 to the shoulder longitudinal axis F (see Fig. 23F) The lever 416 therefore becomes as shown when sliding the heel adjusted by Figures 23A-23C.

Figures 22A-23F show paragraphs 330, 330 ', 330 "with grooves 32 for a fastener 20 on the rear sole portion 4. It should be understood, however, that the other fastening means described above may be used as well (e.g., fastener 20'). in that the heel is preferably slid rearwardly on the sole member 3 in the longitudinal direction of the sole.) The angle of the surface 361, 361 "to the top of the heel 335, 335" in this case preferably becomes flatter forward in the longitudinal direction of the sole.

FIGS. 24A and 24B show a modification of the second mechanism 400 'according to FIGS. 18A to 21 on a sole part 3. The sole part is hereby arranged in a flat heel arrangement (FIG. 24A) and in a high heel arrangement (FIG. 24B). shown.

The second stiffening element 402 'of FIGS. 24A and 24B has a first curved or angled segment 403' in the second transition region B and a second curved or angled segment 405 'in the first transition region A. The front end region 404' of the second stiffening element em 402 'is movably in the front sole portion 6 and the rear end portion 406' movably received in the rear sole portion 4. In the illustrated embodiment, the front sole portion 6 has a recess 407 'for receiving the front end portion 404' and the rear sole portion 4 has a recess 408 'for receiving the rear end portion 406'. By a second reinforcing element 402 'according to FIGS. 24A and 24B, the sole curvature in the first transitional region A is coupled to the hollow curvature in the second transitional region B. The adjustment of the sole curvature in the first transitional region A can lead to a rotation of the reinforcing element 402 'via the second curved or angled section 405', which in turn via the pivoting of the second curved or angled section 403 'to a change of the sole curvature in the second transition region B leads. The sole curvature in the first transition region A therefore causes the arc curvature in the second transition region B (and vice versa).

With the mechanism of FIGS. 24A and 24B, the sole curvature and / or the angle in the second transition region B can thus be adjusted by adjusting the sole curvature and / or the angle in the first transition region A (and vice versa). It is therefore possible, for example, to adjust the sole curve in the first transition region A via one of the first mechanisms described above, which then automatically leads to the adjustment of the second transition region B via the modification of the second mechanism 400 'according to FIGS. 24A and 24B. Another mechanism for twisting the stiffening element (eg a gear or a lever) is therefore not absolutely necessary, but may also be provided in addition.

FIGS. 25A and 25B show a sole part 3 with a tightening aid 700 according to the invention, which allows provisional attachment of a heel to the sole part 3 before it is locked. However, the dressing aid 700 according to the invention can also be used without a further locking system on the sole part 3. For a clearer illustration of the tightening aid 700, only the front sole portion 6 and the middle sole portion 5 are shown in FIGS. 25A and 25B, it being understood by those skilled in the art that the sole portion 3 may also have a rear sole portion.

In the case of the embodiment of FIGS. 25A and 2B, the tightening aid 700 comprises a cantilever arm 710 which extends rearwardly from the middle sole portion 5 in the longitudinal direction L of the sole. On arm 710, a locking projection 712 is provided, which is provided for engagement in a corresponding recess of a paragraph. The cantilever arm 710 is preferably not rigid, but designed so that it is elastically deflected when attaching a paragraph. As further shown in Figure 25B, the cantilever arm 710 may be provided in the region of the rear portion of the first stiffener. Thereby, the cantilevered arm 710 can preferably be inserted into the same recess of the heel as the rear part of the first stiffening element. In the exemplary embodiment of FIG. 25B, the cantilevered arm 710 is arranged between the rear part 11A of a first rail and the rear part 15B of a second rail, which together form the first reinforcing element. The cantilever arm 710 is movable relative to the rear part 1 15A, 1 15B of the first stiffening element.

Figures 26A to 26C show a sequence illustrating the temporary attachment of a heel to the sole portion by means of the donning aid 700. The figures here show a paragraph 30 ", however, inventive dressing aids can also be used with the other paragraph types according to the present invention.

The shoulder 30 "has an opening 720 for receiving the cantilever arm 710, which may optionally be the opening 43" for receiving the rear part 15 of the first stiffening element (see FIG. 26A). The cantilever arm 710 is deflected when attaching the heel 30 "on the rear part 1 15 downward (see Figure 26B) and occurs on reaching an undercut 721 in the opening 720 with the undercut 721 into engagement, so that a renewed peeling of the paragraph 30th is counteracted by the rear part 1 15 (see Figure 26C). In the illustrated embodiment of the paragraph 30 ", the undercut 721 is provided on the upper ceiling 723 of the opening 720.

Figures 27A to 27C show a mechanism 740 for releasing the donning aid 700, which allows the decoupling of the locking projection 712 from the undercut 721 (see Figure 26A) and thus allows the withdrawal of the heel 30 "from the sole part.

In the exemplary embodiment of FIGS. 27A-27C, the mechanism 740 includes two levers 741A and 74IB that act on an end portion 742 of the cantilevered arm 710 to deflect the cantilevered arm 710. At its other end portion 743, levers 741 A and 74 IB are coupled to a user interface 745. The operation of the user interface 745 (which is formed in the illustrated embodiment as a lever which can be pivoted about a pivot point 747) is transmitted via the lever 741 A and 74 IB on the cantilever arm 710, whereby this is deflected (in the illustrated embodiment in Paragraph longitudinal direction down). The pivoting of the user center 745 about the pivot point 747 therefore leads to the deflection of the latching projection 712 downwards, which is thereby decoupled from the undercut 721.

As further shown in FIGS. 27A and 27B, the levers 741A and 741B and / or the user interface may be rotatably supported via the first stiffener element, which is exemplified herein by two rails 14A and 14B. The levers 741A and 741B and / or the user interface 1 e 745 can be arranged between the rails 1 14A and 1 14B. Further, it is optionally possible to form the levers 741 A and 741 B curved, whereby a particularly space-saving arrangement of the lever can be achieved. Instead of two levers 741A and 741B, of course, a single lever or more than two levers can be provided, provided that they fulfill a corresponding functionality.

The tightening aid 700 can also be designed such that after loosening a re-snapping of the cantilevered arm 710 with the undercut 721 is prevented. For this purpose, a slope 725 or 726 can be provided in the opening 720 and / or on the cantilever Ann 710 (see FIG. 26A), which, when the cantilevered arm 710 is deflected when the tightening aid 700 is released, results in a displacement of the heel in the longitudinal direction L of the sole leads to the back. As a result, the cantilever arm 710 can no longer engage the undercut 721 of the shoulder.

Figs. 28A to 28E show a sequence showing release of the donning aid by means of the mechanism 740 of Figs. 27A to 27C. As previously described, in this case the latching projection 712 is deflected by means of the lever 741, which is actuated via the user interface 745. The cantilever arm 710 slides over the ramp 725 (see Figures 28B and 28C), resulting in a relative movement between the shoulder 30 "and the sole member (not shown) on which the mechanism 740 is provided no longer engage the recess 721 when the user interface 745 is released and the cantilevered arm 710 snaps back (see Figure 28D), so the dressing aid no longer interferes with the removal of the heel 30 "so that it can be pulled off the sole member (see FIG 28E). According to embodiments of the invention, the user interface 745 and the actuator 53 Γ of the mechanism for releasing the Verri gelation system 500 'as a single component (eg, as a single lever) may be formed. The invention therefore discloses improved mechanisms that ensure optimum adjustment of the sole shape regardless of the heel height of a replaceable heel. In addition, improved fastening systems are disclosed which allow a simple and secure attachment of exchangeable heels to the shoe sole. The erfmdungs like ace shoes can therefore be adapted to the situation, the user is provided regardless of the heel height a full-fledged shoe available.

The interchangeability of the paragraph also allows a custom design, such as color and shape.
