Description

The The invention relates to a shoe, in particular a sports shoe, with a shoe upper and a sole, the sole one with the Shoe top firmly connected carrier or inner part and a with the carrier or inner part connected sole element.

Shoes This type are well known in the art. In order to and damping behavior of the shoe according to the desired It is still known, especially in the midsole damping elements integrate so that the sole in this particular characteristics be lent.

Out WO 03/092423 A1 is a damping element for one Shoe, especially for a sports shoe, known, which has a special construction. The damping element has a large number of individual elements arranged side by side, each one spring and a damping chamber after Forming a piston-cylinder system. In the form corresponding first and second elements are over a connecting portion connected to each other, wherein under load the sole the smaller trained element enters the larger, for this forms a recording room.

Of the Use of such damping elements in the sole has proven to be very beneficial. However, that is usually after the manufacture of the shoe, the spring and damping behavior of the shoe. amendments This behavior is only - if any - high Effort possible. If the user of the shoe wishes to be active Influence on the spring and damping characteristics of the shoe or if in particular a change to make these characteristics are the relevant ones options limited in the prior art shoes.

Of the Invention is based on the object, a shoe, in particular to create a sports shoe, of the type mentioned above, itself through a simpler option distinguishes the spring and damping properties according to predetermined wishes to influence and adaptable to the individual needs of the user close.

The solution this object by the invention is characterized in that the sole element with the carrier or inner part detachable is connectable, wherein at the carrier or inner part or on the sole element at least one locking element is fixedly arranged with at least one locking element and wherein the at least one locking element with at least one corresponding recess cooperate on the sole element or on the carrier or inner part can. Preference is given to the locking element on the carrier or Inner part arranged, wherein the sole element has the recess.

With this embodiment makes it possible a substantial part of the sole, namely the sole element, interchangeable to design. So can sole elements with different spring and / or damping characteristics quickly interchangeable on the shoe can be securely fixed.

A first training provides that the locking element to a an axis rotatably mounted locking wheel, on which the locking element is arranged. The axis is preferably arranged vertically. Furthermore, the locking wheel on at least a portion of its circumference a knurling have what it takes to that it is easily rotatable by hand to the locking element for locking advance or disengage to release the sole element bring to. The locking element is preferred as being radial outwardly extending Latch formed.

For a simple and secure attachment of the sole element on the carrier or inner part sees a development in that the sole element or the carrier or inner part at least a hook-like projection, which in at least one corresponding Inclusion in the carrier or inner part or can engage in the sole element. The recording can for the hook-like projection an undercut in the vertical direction form. Furthermore, the receptacle and the hook-like projection at a location of the sole element remote from the locking element or the carrier or be arranged inside. In particular, the locking element on the one in the backrest direction lying end of the sole element or the carrier or inner part and arranged the receptacle and the hook-like projection near or on the opposite end of the sole element or the carrier or Inner part. Particularly preferably, the locking element is on in front of the shoe lying end of the sole element or the carrier or inner part.

A particularly firm and secure fit of the sole element on the carrier or inner part is achieved when the sole element or the carrier or inner part has at least one spring element which can generate a spring force which presses the sole element and the carrier or inner part apart in the mounted state , In this case, the spring element may be formed as a tongue which is firmly connected at one end to the sole element or to the carrier or inner part and whose other end is normal from the surface of the Sole element or the carrier or inner part emerges.

Further can be provided that the sole element from a recess having plate on which facing away from the carrier or inner part Side an outsole arranged is. The sole element and the outsole may be glued together.

Farther can the outsole at least about a part of the ground-tread surface of the Shoe as a damping element be formed, which has at least a first element, the essentially in a load direction in the unloaded State of the damping element via a predetermined height extends and, as a hollow body formed, defines a receiving space, in which an associated second Element, smaller in cross-section than the first element at least partially penetrate, wherein the second element itself essentially in the loading direction in the unloaded state of the Damping element over a predetermined Height extends and is arranged coaxially with the first element. This can be a Number of juxtaposed first elements be provided each cooperating with a second element.

One Such damping element is already known as such and described above in WO 03/092423 A1.

The Both elements assigned to one another can be connected to one another via an elastic connecting section be connected, which only between the first element and the second element. Finally, each one first element and a second member together with the connecting portion and the plate form a gas-tight chamber.

At least a part of the second elements may be a prism or cylinder shape have, wherein the prism or the cylinder at least partially is designed as a massive part. At the side facing away from the first element End of the second element may be a sole element as the outer sole to be ordered. This can be done by a number of individual sole parts are formed, each sole member to a second element is arranged.

The first element and the second element can be perpendicular in a section to the loading direction have a mutually corresponding shape. Furthermore you can the first element and the second element in a section perpendicular to the direction of loading a polygonal, in particular hexagonal, Have shape.

Several first elements can be connected in their lateral area or it can be their lateral boundary walls each formed from a common section. The first Element, the connecting portion and the second element are preferred one piece educated. Then it is advantageously provided that the first element, the connecting portion and the second element by a common injection molding are made.

The first and / or second elements preferably have at least partially in the unloaded state of the damping element different heights on. The connecting portion can in the unloaded state of the damping element run flat or curved in a plane perpendicular to the loading direction. With the latter embodiment, the entry of the "piston" is favored in the "cylinder" under load.

In order to this with a return effect done with pressure relief of the damping element can, is the lower axial end portion of the first element and the upper axial end portion of the second member via the connecting portion connected with each other. It is at the connecting section - as well at the first and second element - around a part of elastic plastic material, such that upon application of a loading force on the damping element in the loading direction a deformation takes place. The second element occurs like a piston in the receiving space of the first element one.

The Forming a gas tight chamber within the first and second Elements advantageously has the consequence that after pressure relief of the damping element the initial state is quickly reached again.

Individual "piston-cylinder elements" are forming a damping element with larger areal extent arranged side by side. While the first elements acting as "cylinders" be connected to each other, are the second elements, the "piston", preferably freely side by side.

The with the damping element provided or formed by this sole element can under load absorb the sole in the direction of load energy and discharge them leave the sole again.

The elements are preferably made of plastic, in particular of thermoplastic material. In this case, preference is given in particular to polyethylene, polypropylene, polybutane, polyamide, polyurethane or a mixture of at least two of these Thought plastic. The plastic can be translucent or transparent. The outer sole parts may be made of plastic, preferably polyethylene, polypropylene, polybutane, polyamide, polyurethane or a mixture of at least two of these plastics, or of rubber, wherein the material is not translucent or not transparent.

Of the Material of the first element, the second element and the connecting portion and / or the geometric dimensions of these parts and / or the volume fraction of the solidly formed part for determining the spring and / or damping properties of the damping element selected become.

With Advantage is the first element in the unloaded state the midsole with its axial extent substantially outside the axial extent of the second element. This is to understand that the piston-like second element in the unloaded state of Midsole axially outside of the cylinder-like first element is arranged. Only when loaded of the damping element in the loading direction then enters the "piston" in the "cylinder".

The Carrier- or inner part and at least part of the sole element, in particular the plate, are preferably as injection-molded plastic parts educated.

Especially It is advantageous that an interchangeability of the sole element possible so that the shoe when needed to desired (spring and damping) properties can be adjusted.

When additive measure can be provided that the plate, which is part of the sole element is, with the outsole by means of a form-locking Connection is connected. Preference is given to a plug connection between two parts, namely between the plate and the outsole, thought, which can be joined by pinning, whereby by positive locking the transmission of usual personnel while the use of the shoe can be recorded.

The positive Connection between the plate and the outsole may be detachable, making it possible will, if necessary, the outsole lose weight and replace it with another. The positive connection between the plate and the outsole For this purpose, preferably provided with at least one locking projection have resiliently biased clip closure. Through a such clip closure can the outsole fixed to the plate latching, so that sufficient strength against burdens by usual using powers given is; However, the clip closure can also be solved again, around the outsole replace if necessary.

The positive Connection between the plate and the outsole may also be alternative inseparable be educated. It is especially thought that the Plate and the outsole the positive Bonded together.

Especially it is preferably provided that the positive connection by at least one on the plate or on the outsole and arranged from the sole plane in the vertical direction (with the usual resting of the shoe on the floor) extending into a projection conforming recess engages in the other component.

By This configuration makes it possible by Force application between plate and outsole in vertical direction to put these two parts together, so that they are secured against unintentional disconnection. The assembly process the sole is thereby considerably simplified.

Of the Lead and the associated Recess have in a section perpendicular to the vertical direction preferably a polygonal, in particular a hexagonal, shape; also a circular one Design is possible. Preferably, a number of juxtaposed projections and Recesses arranged on the plate or on the outsole.

In the drawing is an embodiment of Invention shown. Show it:

1 schematically a shoe, viewed from the side,

2 in exploded view in the heel area of the shoe according to 1 arranged sole, namely a carrier or inner part and a sole element detachably connected thereto,

3 the carrier or inner part along with the assembled sole element in section along the longitudinal axis of the shoe,

4 the support or inner part of the sole in plan view and

5 the section AB according to 3 for a part of the sole.

In 1 is a shoe, namely a sports shoe, shown only very schematically. Of the Shoe has a shoe upper in a known manner 1 that with a sole 2 connected is.

The sole 2 is designed so that it expands in the front sole area over a certain areal extent. In the rear sole area, it also expands over a defined areal extent.

Of the hereinafter described structure of the shoe or its sole applies for the Behind the sole. However, an appropriate design be provided in the front spar area, but not is mandatory. Likewise, the solution described below can only be be provided in the front sole area.

The construction of the sole 2 goes into more detail 2 out. The sole 2 consists of two (soles) parts, namely a carrier or inner part 3 and a sole element 4 , In the plate-shaped carrier or inner part 3 it may be a component which is connected at its top with an insole, an insole, a Strobelsohle or directly to the upper material, the connection between the shoe upper 1 and the sole 2 forms. Instead of a plate-shaped configuration, a curved, three-dimensionally formed, z. B. cup-shaped element 3 be provided.

The carrier or inner part 3 is with the shoe upper 1 connected. The compound can be produced for example by an adhesive process. In this case, the in 2 to be seen upper surface of the carrier or inner part 3 directly with the shoe upper 1 bonded.

The sole element 4 consists of a plate 16 with their top with the carrier or inside part 3 can be detachably connected and the underside of an outsole 17 wearing. In the embodiment, the outsole 17 stuck with the plate 16 connected. In the plan view, the carrier or inner part 3 and the plate 16 or the outsole 17 a corresponding form.

Between the carrier or inner part 3 and the sole element 4 ( 16 . 17 ) is - as mentioned - provided a detachable connection. This is done as follows:
The carrier or inner part 3 has two recesses 22 and 23 for receiving two counter-elements 24 and 25 at the plate 16 are formed, s. 2 , Here is the counter element 24 as a hook-like projection 11 trained, with a recording 12 in the carrier or inner part 3 can work together so that after hooking the hook-like projection 11 into the recess 22 the plate 16 of the sole element 4 with undercut in the carrier or inner part 3 is fixed; the hook-like projection is then on the recording 12 on, as indicated by the dash-dotted lines in 2 is indicated. The cuboid counter element 25 the plate 16 fits in the recess 23 in the carrier or inner part 3 ,

The counter element 25 has laterally a slot-shaped recess 7 on. This is designed or positioned so that it with a locking element 6 can cooperate, the component of a carrier or inner part 3 arranged locking element 5 is. The locking element 5 still has a locking wheel 9 , which is a vertical axis 8th is rotatably arranged. At the circumference of the locking wheel 9 is a knurling 10 arranged, which makes it easier for the user of the shoe, the locking wheel 9 around the axis 8th to turn. By such a rotation, the locking element 6 optionally engaged with the recess 7 be brought (whereby the counter element 25 and thus the sole element 4 relative to the carrier or inner part 3 is set) or disengaged (causing the plate 16 from the inner or carrier part 3 can be deducted and removed).

This makes it possible in a simple manner, the sole element 4 on the carrier or inner part 3 releasably fix and replace if necessary.

So in the assembled state, the plate 16 firmly on the carrier or inner part 3 is present, are made of the material of the carrier or inner part 3 two tongue-like spring elements 13 formed. The spring elements 13 are with their one end 14 cohesively with the carrier or inner part 3 connected; with their other end 15 extend slightly - as is in 2 can be seen - in the relaxed state of the plane of the carrier or inner part 3 out.

This ensures that after insertion of the sole element 4 in the carrier or inner part 3 the spring elements 13 in the plane of the carrier or inner part 3 be pushed back, leaving a spring-biased bond between the carrier and the inner part 3 and the plate 16 of the sole element 4 is present.

In 3 is easy to recognize, as the hook-like projection 11 the plate 16 on the recording 12 the carrier or inner part 3 to come to rest. Furthermore, here is the position of the locking wheel 9 to see in which the locking element 6 into the recess 7 in the counter element 25 engages and so does the plate 16 on the carrier or inner part 3 sets.

Out 4 go the two positions of the locking wheel 9 or the locking element 6 in which a lock or unlock the plate 16 relative to the carrier or inner part 3 is present. Here is the solid element with solid lines 6 sketched in the locked position, while with dashed lines the locking element is shown in the unlocked position.

Out 5 Finally, the structure of the outsole goes 17 protruding at the plate 16 is fixed, preferably glued to this is.

The outsole 17 consists in the embodiment of a plurality of damping elements, which are constructed in the manner of a piston-cylinder system (of course, there are other embodiments of the outsole in question, for example, a conventional foamed midsole with outsole). It should be noted that it is not necessary that the entire sole be constructed as explained. For example, only the front sole area can be designed as described, while the rear sole area can be formed in a previously known manner - or vice versa.

The individual damping elements 18 . 20 that the outsole 17 form, are in the embodiment - in loading direction R of the sole 2 considered - formed with a hexagonal basic shape in the manner of a honeycomb pattern.

Each damping element has a first element 18 which extends over a defined height H and a receiving space 19 forms. Via a web-shaped connection section 21 is that of the carrier or inner part 3 opposite end of the first element 18 with a second element 20 connected, the one to the shape of the first element 18 has corresponding shape - viewed in the direction R -, ie, the second elements 20 have a hexagonal shape in the embodiment. The second element 20 extends over a height h, which does not have to be equal to the height H.

How out 5 it can be seen, the dimensions - the width of the first element 18 and the width of the second element 20 - chosen so that the second element 20 when loading the damping element in the loading direction R in the receiving space 19 can enter through the first element 18 is formed. The first element 18 and the second element 20 Consequently, work in the manner of a telescopic damper, wherein the first element 18 acts as a "cylinder" into which the second element 20 can occur in the manner of a "piston".

Will on the outsole 17 abandoned a force in the direction of R, as is done when the shoe hits the ground, deformed in particular the elastic connecting portion 21 which is the exclusive connection between the first and the second element 18 . 20 represents, so that, as explained, the second element 20 in the manner of a piston in the receiving space 19 of the first element 18 entry.

In order to positively influence the jounce behavior, that of the first element 18 , the connecting section 21 and second element 20 enclosed space to be formed gas-tight.

The embodiment is based on that a sole element 4 In the same way, however, it is also possible for the plate to be used in the same way as the "piston-cylinder damping elements" explained 16 For example, simple honeycomb cells or round cells are attached, which are interchangeable by the inventive design. The degree of coverage of the sole area is arbitrary.

In the exemplary embodiment is for locking the rotatable wheel 9 intended. In general, any other options for locking come into question. As an example, a solution with a latching means is called with a pawl-like projection, which cooperates with a correspondingly formed counter element.
