Description

The invention relates to a shoe according to the preamble of claim 1. Shoes have been used for a long time to increase the running comfort and usually consist of a shoe upper, a shaft bottom and an outsole. The shoe upper, the shaft bottom and the outsole are usually firmly connected to each other and form a functional unit in the finished shoe, through which the shoe can be assigned, for example, a specific use. For example, so-called "loafers" usually have a low, d. H. Typically, to below the ankle-reaching shoe upper made of a relatively solid material, such as leather, while sports shoes or so-called "sneaker" usually have a shoe upper of a soft, but stability-providing, and lightweight material. With regard to the sole, hitherto known shoes also differ, in particular with regard to their respective field of application. For example, shoes suitable for off-road riding have a profiled outsole, while, for example, indoor sports shoes or climbing shoes have a smooth sole. In addition, the outsole of respective shoes also differs in their hardness, which is adapted to a particular field of application. A disadvantage of these previous shoes is that a buyer or wearer of previous shoes could only resort to such combinations of shoe upper and outsole, as offered by a shoe manufacturer, where it was not possible for a customer to purchase a shoe that was customized was, for example, in terms of a height of the shoe upper, the material of the shoe upper, the color of the shoe or the type, hardness and flexibility of the outsole.

This disadvantage of previous shoes was due to the WO 2011/080779 A1 It is proposed that there is a modular construction of a shoe, wherein a shoe upper can be combined individually with different soles as well as with a raised heel. For this purpose, there is proposed to insert a surface element whose shape substantially corresponds to an insole in the upper shoe, wherein the surface element downwardly, ie towards the sole directional locking pins, which passes through holes on the inside of the bottom of the upper shoe so extend, that they protrude from the underside of the upper shoe and can engage in, provided in the sole, holes, so that the shaft bottom and the associated shoe upper is fixedly connected to the arranged in this surface element with the sole.

A disadvantage of in the WO 2011/080779 A1 The proposed solution for producing a modular shoe is that the surface element which is inserted into the upper shoe is an additional rigid component that adversely stiffens the sole structure of the shoe and leads to an unpleasant hard wearing feeling and adversely increases a weight of the shoe.

The invention is based on the object to solve the above problems and to provide a shoe that is modular, individually to customer requirements, especially with regard to a desired range of applications and ease and flexibility and a good pedaling and running can be adjusted.

This object is achieved by a shoe according to claim 1.

In particular, the object is achieved by a shoe having a shoe upper with a shaft bottom, the shoe upper being connected to an outsole by a connecting element fixing the shaft bottom to the outsole, the connecting element having at least one web extending substantially over the length of the shaft bottom extends and extend from the lateral transverse webs away.

An essential point of the invention is that the connecting element with which the shoe upper is fastened via the shaft bottom to the outsole, is constructed from at least one longitudinal and a plurality of lateral transverse webs connected thereto, the transverse webs being arranged at a distance from one another. The same applies to any multiple longitudinal webs. This configuration of the connecting element according to the invention makes it possible to make the connecting element light on the one hand and extremely flexible on the other hand, so that it is possible using the connecting element according to the invention to provide a shoe whose sole hardness, in particular also by means of a type and configuration of the connecting element, is customizable. This individual adaptability of the sole hardness of the shoe according to the invention is based on the fact that it is possible to dimension both the longitudinal web and the transverse webs differently, for example with respect to their thickness and / or width, and in this way to provide webs which are of different hardness or softness and are different torsionally stable and / or rigid. For this purpose, the webs, for example, partially thickened, widened, provided with stiffening ribs or be formed of different materials.

According to one embodiment of the invention, it is possible for the at least one web extending substantially over the length of the shaft bottom to extend along an outer line following the shaft bottom and for the transverse webs to extend substantially only on one side of the longitudinal web. It is also possible that such a longitudinal ridge extends on both sides of the shaft bottom and substantially following one or both outer edge of the shaft bottom, while the transverse webs extend between the two longitudinal webs, wherein it is possible that the two longitudinal webs only by a few transverse webs are interconnected, while a part of the transverse webs adjacent only on one side to a longitudinal web and on the other side has a free end.

According to a further embodiment of the invention, it is also possible that the longitudinal web extends substantially completely around the circumference of the shaft bottom, wherein this longitudinal web may be broken. In the presence of a plurality of longitudinal webs or a longitudinal web extending completely around the circumference of the shaft bottom, the transverse webs can either extend substantially parallel between the respective longitudinal webs or can be connected between the respective longitudinal webs to form a net-like pattern, optionally with free web ends ,

According to a further embodiment of the invention, the connecting element fishbone-like or in the manner of a spine is formed with laterally projecting ribs, wherein the connecting element has at least one central or central web with laterally extending from the central web transverse webs. In the context of the invention, the term "central web" is understood to mean a web or optionally a double or triple web, which extends from the heel end surface to a toe end of the shoe and substantially in the surface of the shaft bottom, for example essentially centrally in the surface of the shaft bottom, runs.

An essential advantage of a herringbone or in the manner of a spine with laterally constructed by this protruding ribs connecting element is that this is a very simple structure and on the other in a very simple way individually adaptable to the respective desired requirements by, for example, a ( or multiple) longitudinal web (s) and / or transverse webs are used, which are individually customized with regard to hardness, bending behavior and torsional stability, so that the connecting element as a whole is adaptable to exact customer-specific wishes.

According to one embodiment of the invention, the webs of the fastener in plan view define a surface that substantially corresponds to a surface of the shaft bottom or a corresponding insole, or substantially a surface of a foot, which is bounded by an enveloping peripheral line around the foot Connecting element is preferably formed as a surface element. The term "surface element" in this context is to be understood that the upper surfaces, resp. Limitations of the webs of the connecting element form a, possibly curved, surface when the respective upper boundaries of the webs are connected in thought. In this way, in terms of its lateral extent, the connecting element essentially corresponds to such an extension of an insole and / or of the shaft bottom.

According to the invention, latching pins are arranged on the bottom side of the at least one middle web and / or the transverse webs in the assembled state, in particular integrally formed, whose free ends are widened for latching on the outsole, in particular in the form of mushroom-like caps. According to an alternative embodiment, these locking pins may also be designed as latching hooks and / or have the form of barbs.

The shaft bottom of the shoe according to the invention in turn has through slots and / or through holes through which the locking pins can be guided and latched with complementary locking recesses on the outsole. Such locking can for example be realized in that a mushroom-shaped cap of a locking pin engages in an undercut of a complementary locking receptacle, or by unintentional release of the locking pins from the locking receptacle is prevented by latching hook. If desired, the latching can be made detachable, for example, by an adapted design of the latching receptacle, which can be designed, for example, as a narrowing slot so that a latching pin with a widened end cap or a latching hook pointing to the side in a wide opening Inserted locking receptacle and then can be moved in the direction of a narrow opening of the locking receptacle, so that the locking pin is fixed in the narrowed portion of the locking receptacle. In this case, the connecting element is preferably displaceable and fixable, for example, in several parts with fixing elements and / or spacers (s) formed.

Furthermore, the connecting element according to the invention may be formed in one or more parts, wherein the individual parts of a multi-part connecting element locked at a predetermined distance from each other and / or can be connected together. Such a connection may be an articulated, in particular pivotable about a longitudinal axis of the connecting element connection, which may be realized, for example, with, in particular einschnappbaren, ball and / or plug joints. The use of plug connections with or without latching has proved to be particularly simple at this point. In the assembled state of the connecting element, a slipping or loosening the connections of the individual parts of the connecting element is also not to be feared, since the individual parts of the connecting element are fixed in each case by the locking pins fixed to the outsole, so that slipping of the individual parts the connecting element or the connecting element as a whole in an advantageous manner is not possible.

According to the invention, the connecting element is thus arranged in the installed state within the shoe upper above the shaft bottom, wherein the latching pins located on the connecting element, respectively on the webs of the connecting element, extend through passage slots or through holes which are arranged in the shaft bottom of the shoe upper. These locking pins then engage below the shaft bottom in each case in each of the locking pins complementary latching receptacles, which in turn are provided on or in the outsole. The locking receptacles may in this case be designed so that they extend completely through the outsole or in the form of blind holes in the outsole are formed, in which an attachment of respective locking pins is provided. It should be mentioned at this point that in addition to or in combination with a locking connection, other detachable or non-detachable connections between the connecting element and outsole are possible, such as adhesive, screw, Klip, Velcro and / or rivet.

According to the invention, it is possible to match the number of the respective latching pins and the latching receptacles complementary thereto; However, it is also possible to provide in the outsole, a larger number of locking receptacles to allow in this way the use of different connecting element, in which the respective webs, namely the at least one longitudinal web and laterally extending away therefrom transverse webs, in another Configuration that is adapted to a different customer request or purpose than a first configuration. It is also possible to provide the shaft bottom with corresponding passage slots or through holes, so that not only the use of a specific connecting element with corresponding associated locking pins, but also an exchange of a first connecting element by a second or further connecting element with differently arranged locking pins is possible.

According to one embodiment of the invention, the shoe upper and the shaft bottom are connected together to form a boot-like structure, wherein the shoe upper and / or the shaft bottom are preferably made of a flat-knit material and the shoe upper is in particular integrally formed with the shaft bottom.

Alternatively, the shoe upper and the shaft bottom can also be circular knit to form a footlet-like structure.

Furthermore, it is possible that the shoe upper and / or the shaft bottom is made of leather or another conventional material for producing shoe stems as well as a shaft bottom or comprises such a material.

According to a further embodiment of the invention, the at least one longitudinal or middle web of a course or a usual rolling movement of a foot following, substantially wave-shaped, in particular substantially S-shaped, curved, formed. The term "undulating" is in this context not as vertically undulating, but as substantially horizontal, d. H. in a sole plane, to understand undulating; the same applies to the S-shaped arrangement of the longitudinal or central web of the connecting element according to the invention, so that it is possible to stand in a comfortable position on the connecting element and to walk and run.

In this regard, it should be noted that in a conventional application of the connecting element according to the invention used for the manufacture of a shoe an insole can be arranged above the connecting element, but it is also possible to dispense with such an insole and directly load the connecting element with one foot, without that unwanted pressure points or load peaks occur.

For this purpose, according to a further embodiment of the invention, it is possible to space the webs such that a substantially uniform surface loading, which ensures a comfortable contact feeling of a foot with the connecting element, is provided. Alternatively, however, it is also possible within the scope of the invention that the shaft bottom is formed so that recesses are provided in the regions of the webs of the connecting element, so that in an inserted connecting element of shaft bottom and Connecting element results in a uniform surface on which a foot, even under load evenly and anatomically correct, go and run and gives a comfortable fit for the user, wherein the connecting element is quasi embedded in the shaft bottom and / or sunk.

According to a further embodiment of the invention, the locking pins are formed integrally with the webs. In this way, the webs and the locking pins and possibly the complete connecting element can be produced inexpensively by injection molding and / or by 3D printing or another conventional manufacturing process in a simple manner.

Furthermore, the outsole of the shoe according to the invention, at least in the region of the complementary locking receptacles on its underside at least one recess, preferably in the region of each latching a recess for receiving the mushroom-shaped caps and / or hooks. In this way it is possible quasi sunk to install the mushroom-shaped caps and / or hooks of the locking pins without the respective caps and / or hooks with the substrate, such as pavement or asphalt, comes into contact. The outsole of the shoe according to the invention is thus optimally adaptable to the respective intended use on its underside, since the locking pins do not project with their ends over the lower surface of the outsole.

According to an alternative embodiment of the invention, the locking pins may be extended with their ends so far that they project beyond the lower surface of the outsole, so that the lower ends of at least some locking pins protrude, for example spikeartig from the lower surface of the outsole, so that a shoe with usually smooth sole can be used, for example, even in snow or icy slippery. For this purpose, the protruding from the plane of the tread tips of the locking pins may for example consist of a hardened material and / or metal.

The connecting element according to the invention is made of a plastic and / or metal and / or carbon, wherein suitable plastics such as polyethylene, polypropylene, polyamide, polyurethane or polyethylene terephthalate in question, wherein mixtures of said plastics or other suitable and conventional plastics are used can, so that the spine-like connecting element in terms of hardness, bending behavior, torsional behavior can be adjusted optimally and customizable to the customer specifically voiced wearing and use and comfort properties.

Furthermore, it is possible to adjust the bending and torsional rigidity by using suitable materials and, in particular in the case of multi-part connecting elements of suitable articulated joints, in order to adjust the running pattern and the running properties of the shoe according to the invention. Furthermore, the connecting element may at least partially have a reinforcement, for example of metal and / or carbon, in particular of carbon fibers, and / or comprise a framework, for example of wire. Furthermore, the struts of the connecting element may also have different thicknesses or widths in certain regions, in order in this way to set a stiffness or to generate certain desired pressure points.

In this context, it should also be noted that at the free ends of the transverse webs as desired sole-edge webs may be formed, which may be integrally formed with the transverse webs or via a connection, in particular a hinge connection, may be connected to the transverse webs. The sole edge webs may be formed only as a slight broadening of the ends of the respective transverse webs or extend almost completely over the respective distance of a cross-piece end to an adjacent crosspiece end. The edge webs can in this case only extend to one side of the crosspiece end and / or on both sides of the crosspiece end. In this way, it is advantageously possible to stabilize the free crosspiece ends over the shaft bottom and to improve the torsional strength of the cross braces.
