SH.Q.E
The present invention relates to a shoe.
Shoes consist of a sole and an upper which surrounds the foot resting on the sole. The soles of shoes often have damping means by which the load exerted on the foot or on the entire body of the runner is eased when running. Known damping means for example are air cushions or gei-filled. cavities.
A sole with a plurality of damping elements Is known (EP 0 695 514 Al). This sole has, In the heel area, the m tatarsal. area, and the ball of the foot, a plurality of holes. extending in the transverse direction and intended to serve as damping cushions. These holes are given a variety of shapes and sizes and have a.
correspondingly hard or soft damping effect: In one embodiment, a recess Is made in the sole from the rear end which is open at the sides so that the area of the sole beneath forms a plate that projects freely to the rear. Such a.sole has a very soft damping characteristic in the heel area.
A sole is'also known for an exercise shoe (DE 94 13 496 U1.) by which running on the level is made more difficult for training purposes. This sole Is cut away in the area -associated with the shoe heel so that the wearer of the shoe can run essentially only in the vicinity of the balls of the feet. As a result, an effect like that obtained running uphill on a 15 slope or vvhen dimbing stairs is achieved. A
shoe of this kind that promotes ninning on the balls of the feet is unsuited from the health standpolnt since, when running on the bails of the feet, the foot or shoe is placed on the ground with the leg extended and the Impact load is transferred directly to the knee and hip joints and the spinal column.

In view of the above disadvantages and shortcomings of the shoe known from -the prior art, the goal of the present invention is to provide a shoe with which the shock loads that occur when running are transmitted only to a very slight degree, if at all, to the knee and hip joints and to the spinal column.
This gool is achieved by a shoe having a sole that extends from a rear heel area through a metatarsal area to a front ball or toe area, said sole being made of a sole body and a sole covering located on the underside of the sole body and a recess that extends approximately from the metatarsal area to the heel area and Is provided between the sole body and the sole. covering; the area of the sole covering associated with the recess forms a pivoting element that Is designed to pivot around a pivot axis that is located in the end area of the reoess,and fadng the metatarsal area.
The shoe according to the present invention has a sole composed of a soie body and a sole covering, with a recess extending approximately from the metatan3ai area to the heel area, said recess being provided between the sote body and the sole covering so that the area of the sole covering associated with the n3cess, when placed on a support, is pivoted away upward around a pivot axis so that the shoe is placed very sofNy on the support.
When the shoe is placed on the support in the vicinity of the pivot axis, it tilts around the pivot axis with the Wl or toe area on the support. As a result, the foot and the iovwer leg are displaced slightly forwarci and the knee is automatically bent slightly. A leg bent at the knee aooepts the impact load ttsrough the bones of the skeleton and the surrounding muscuiature without the impact load being transmitted to the joints or the spinal column.

impact load exerted on the sensitive joints or on the spinal column is considerably reduced.
In the standing phase, the wearer of the shoe is also placed in a therapeutic posture, in other words a posture with the knees forced to bend at an angle so that the spinal column is also relieved of a load when standing.
Hence, the invention is based on the knowledge that in conventional shoes, despite costly and cumbersome damping elements, the impact load is transmitted directly to the joints and the spinal column since, with these shoes, the foot or the shoe can be placed on the support with the leg extended.

Figure 5 Is a side view of a fourth embodiment of a shoe according to the prdsent invention; and Figure 6 Is a side view of the shoe in Figure 5 with the heel area being subjected to a load as the foot is set down or rolled away, Identical referenca numbers in Figures 1 to 6 refer to the same or similar parts of the shoe according to the present invention.
Shoe I according. to the present invention has a sarie 2 and an upper 3 located thereon, said material surrounding a foot (not shown in Figures 1 to 6) of a runner. Upper 3 can be dosed by shoelaces, hook and loop fasteners, or the like and has an opening 4 through which the foot extends upward in the erea of the ankie.
Sole extends from a rear heef area 6 through a metatarsal area 7 to a trcurt ball or toe area 8, with each of these areas 6, 7, 8= extending over approximately one-third, of the length of sho 1.
Sole 2 is made of a voluminous sole body 10 and a sole covering.ll located at Its underside. Sole body 10 consists of a materiai with good damping properties such as a poiyester-urethane (PU) foam for exampie, and soie covering 11 consists of an abrasion-resistant material that is preferably profiled on its underside, hard rubber for example.
The entire sole 2 has a thickness that Increases from. bal I and toe area 8 to heel area 6 so that sole 2 forms e,wedge In a side view. The sole top forms an angle a with the underside of the sote and this angie, is in the range of approximatety 8 to approximately 200.

Between sole body 10 and sole covering 11 is a recess 13 that expands in a wedge shape from metatarsal area 7 to heel area6 .Soie body 10 forms a stop surface 15 adjacent to recess 13.
Sole covering 11 projects freely rearward adjacent a point 13a of reoess 13 that points toward ball and to area 8, with this=area of sole covering 1 i projecOng freeiy rearward to form a pivoting element 18 v,rhich can be pivoted upward against stop surfaoe 15 of sole body 10 around the pivoting area, adjacent recess point 13a, behveen pivoting element 18 and the rest of soieõcovering 11.
A pivot axis 20 extends pivotabiy relative to pivoting element 18 through soie covering 11 in the transverse direction adjacent to recess tip 13a.
A pivot angie 0 between stop surfaoe 15 and pivoting eiement 18 is in the tange of approximately 100 to approximateiy 300, especially In the range from approximately 1-5 to approximately 20 . The tip 13a of mcess 13 and hence pivot axis 20 are located in._theõarea between_the lengthwise center of shoe I
and heel srea 6 which extends over approximately one-third of the length of shoe 1.
Sole covering 11, especiaiiy in the area of pivot axis 20 and pivoting element 18, has considerable dimensional stability and/or flexurai atrength and Is fiber-reinforced, so that sole covering 11 has considerable intrinsic stiffness.
As shown in Figure 2, shoe 1, because of the wedge shape of the entire sole 2, when placed on a support when running, contacts a support by its soie oovering 11 in heel area.6 and thus support 22 by its pivoting element 18. Pivoting element 18 of sole covering 11 is pressed around pivot axis 20 against stop surface 15.
This pivoting movement of pivoting element 18, despite the considerable dimensional stability of sole covering 11, results In a very gentle, yielding placement of shoe I on support 22. The restoring force of sole covering 11 is . =. , 15/02 2005 TUF 11:35 FAX ANWAELTE/ATTORNEYS Id1007/015 chosen so that no more than 300,6 and if possible only 10% of the weight of the runner (65 to 75 kg for example) for which shoe 1 is designed Is sufficient to press pivoting element 18 against stop surface 16.
When pivoting element 18 strikes stop surface 1 S(see Figure 2), the area of sole 2 or of sole covering 11 that extends from pivot axis 20 to bali or toe area 8 is inclined upward and fonnrard relative to support 22 around pivot angle A. Sole covering 11, when pivoting element 18 is bent away, has an obtuse angle of nearly 18011 in the vicinity of pivot axis 20.
When pivoting element 18 strikes stop surface 1.5, the gentle placement process in heel area 6 is terminated and the load exerted on sole 2 by the foot of the runner is distributed approximately uniformiy over the entire length of sole 2. As a resuit, and because of the momentum of the runner directed in the running din3ction, shoe 1 tips fonward around pivot axis 20 and rests its forward area of sole covering 11 on support 22.
This tilting of shoe I causes the foot and lower leg of the runner to be dispieced slightly forward in the running direcUon and the knee is bent slightly between the lower leg and upper leg. The maximum load on the foot or on sole 2 appears only after shoe I has tilted or after the runner's knee has bent so that the recoil produced by the impact on support 22 encounters a leg that Is already bent at the knee and which can accept the impact load In a gentle manner with elastic flexibility by means of the knee Joint with its skeleton and muscies, Shoe 1 according to the present invention thus Causes automatic roiling of the foot when running so that by comparison with conventional shoes, a considerably more protective transmission of the impact load to the body is produced.
A second embodiment of the shoe according to the present invention is shown In Figure 3. This shoe I essentially corresponds to the shoe I described above;
15/02 2005 TUE 11:35 FAX ANWAELTE/ATi'ORIVEYS 10008/015 accordingly, the same or similar components have been given identical referonce numbers.
Shoe 1 according to Figure 3, in wedge-shaped recess 13, has a material element in the form of a material vwedge 25 made of an open-pored foam. This material wedge 25 !s mounted on stop surface 15 of sole body 10 and on pivoting element 18 by means of a glued connection.
Sole covering 11- is divided by a siit 27 in the area of pivot axis 20. The frameworh of the invention, of course, includes an embodiment without a siit (see for example the fourth embodiment of the present invention shown in Figures 5 and 6).
Advantageously, sole covering 11 is flexible In the vicinity of pivot axis 20 and formed by a taper since, in this embodiment of shoe 1, it Is advantageous that during the setting down phase of shoe I on support 22 in heel. area 6, the restoring force of pivoting element 18 is applied if possible only by material wedge 25 in order to ensure that shoe I is set down on support 22 as softly as possible.
A reinforcing piato 29 is placed In sole body 10 that extends from the iengthwise center of shoe I to rear heel area 6. The reinforcing plate 29 consists of a metal plate or a fiber-reinforced plastic plate and is located at a distance above a pressure distribution part 16, with reinforcing plate 29 being adapted to the curvature of pressure distributing part 16. The reinforcing plate 29 extends In the transverse direction over nearly three-fifths to four-fifths of the width of shoe I
and during the set-down phase during which pivoting element 18 is pressed ag?inst stop surface 15, that sole body 10 cannot be tilted downward by the heel.
15/02 2005 TUE 11:35 FAX ANWAr;L'1'E/A'171'UItNbYS 4qjUUH/Ulo g A third embodiment of*the invention is shown in_Figure 4. This. shoe I has essentially the same structure as shoe I described above; accordingly, the same or similar oomponents have identical reference numerals.
The wedge-shaped recess between stop surface 15 and pivoting element 18 Is enclosed by an air bellows 31. Two holes 32 are made in sole body 10, said holes terminating at one end at stop surface 15 and at the other end externally on sole body. 10.
A valve 33 is placed In each of the two holes 32 which limits the escap of air from air beHows 31 to the outside so that when pivoting element 18 is pressed toward stop surface 15 by the limited escape of air during the pivoting movement of pivoting element 18, a predetermined reiativeiy gentle resistance is offered in opposition.
When the pressure by vvhich pivoting element 18 is pressed against stop surface 15 is reieased, pivoting eiement 18 again pivots into the initiai position vvhich runs as a straight line extension of the rest of sole covering 11, whereupon vaives open and permit a rapid flow of air into air bellows 31.
Pivoting element 18 of sole covering 1'! is made In one piece with the rest of sole ' covering 11 and has a certain degree of dimensional stabiiity or flexurai strength so that it automatically pivots back into the initial position following compression of air bellows 31.
The fourth embodiment according to Figure 5 essentially corresponds to the second embodiment according to Figure 3, with the only difference being that recess 13 is not wedge-shaped but essentialiy in the form of a circular section and is filled with a-matQriai element 25 made of open-pored plastic.

15/02 2005 TUB 11:36 FAX ANWAELTE/ATTORNEYS 1SIU1u/U16 According to a feat" essential to. the invention, sole 2 Is raised laterally or provided with avery thin lateral covering in the form of side walls made of rubber .
which cover the plastic core externally for protection and can readily be compressed like a bellovvs.
In the present invention, therefore, the action of recess 13 Is so designed that when rolling on pivot axis 20, recess 13 or its filling does not exert an elasticaily flexible effect through material element 25 but yields with. practically zero force up to the stop when soie covering 11 comes to rest against a hard unyielding area of shoe 1.
Shoe 1 according to the four embodiments described above, is characterized by the fact that when nmrgng, a rolling of shoe 1. or the foot on the_suppc~rt is automatically produced. This is effected by vuedge-shaped -recess 13 between sole body 10 and sole covering 11, since sole covering 11 deflects upward with its pivoting element 18 when subjected to a load In heel area 6 and forms ina .gently yielding fashion an obtuse angle at sole 2 whose point ls'iocated In the vicinity of pivot axis 20.
Shoe I tiits around this obtuse angle in a forward direction so that the knee of the runner Is bent and the_ impact load is received by the runner vhth a bent knee.
The impact load is not trannsmitted to the sensitiv.e joints and spinal column but is received by the skeleton and the corresponding musculature.
The Invention is not limited to the above four embodiments described earlier;
the Individual skilled In the art can readily devise additional modifications of the invention. For example, the scope of the invention also covers an embodiment In which sole body 10 and sole oovering 11 are made in one piece andlor of one part.
In the standing phase, the wearer of the shoe is also placed in a therapeutic posture, in other words a posture with the knees forced to bend at an angle so that the spinal column is also relieved of a load when standing.
Hence, the invention is based on the knowledge that in conventional shoes, despite costly and cumbersome damping elements, the impact load is transmitted directly to the joints and the spinal column since, with these shoes, the foot or the shoe can be placed on the support with the leg extended.
In accordance with an aspect of the present invention, there is provided a shoe comprising a sole that extends from a heel area through a metatarsal area to a front ball or toe area, said sole being composed of a sole body and a sole covering formed on an underside of the sole body and a recess extending approximately from the metatarsal area to the heel area, said recess being provided between the sole body and the sole covering, with the sole covering forming a pivoting element in an area associated with the recess, said pivoting element designed to pivot around a pivot axis located in an end area of the recess facing the metatarsal area, the end area of the recess facing the metatarsal area being defined by a tip, the pivot axis being located in an area between a lengthwise center of the shoe and the heel area, with the heel area extending over approximately one-third of the length of the shoe, at least one material element being located in the recess, said at least one material element being made of a flexible, soft material and being made approximately wedge-shaped or approximately in a shape of a circular section.

Between sole body 10 and sole covering 11 is a recess 13 that expands in a wedge shape from metatarsal area 7 to heel area6 .Soie body 10 forms a stop surface 15 adjacent to recess 13.
Sole covering 11 projects freely rearward adjacent a point 13a of reoess 13 that points toward ball and to area 8, with this=area of sole covering 1 i projecOng freeiy rearward to form a pivoting element 18 v,rhich can be pivoted upward against stop surfaoe 15 of sole body 10 around the pivoting area, adjacent recess point 13a, behveen pivoting element 18 and the rest of soieõcovering 11.
A pivot axis 20 extends pivotabiy relative to pivoting element 18 through soie covering 11 in the transverse direction adjacent to recess tip 13a.
A pivot angie 0 between stop surfaoe 15 and pivoting eiement 18 is in the tange of approximately 100 to approximateiy 300, especially In the range from approximately 1-5 to approximately 20 . The tip 13a of mcess 13 and hence pivot axis 20 are located in._theõarea between_the lengthwise center of shoe I
and heel srea 6 which extends over approximately one-third of the length of shoe 1.
Sole covering 11, especiaiiy in the area of pivot axis 20 and pivoting element 18, has considerable dimensional stability and/or flexurai atrength and Is fiber-reinforced, so that sole covering 11 has considerable intrinsic stiffness.
As shown in Figure 2, shoe 1, because of the wedge shape of the entire sole 2, when placed on a support when running, contacts a support by its soie oovering 11 in heel area.6 and thus support 22 by its pivoting element 18. Pivoting element 18 of sole covering 11 is pressed around pivot axis 20 against stop surface 15.
This pivoting movement of pivoting element 18, despite the considerable dimensional stability of sole covering 11, results In a very gentle, yielding placement of shoe I on support 22. The restoring force of sole covering 11 is . =. , 15/02 2005 TUF 11:35 FAX ANWAELTE/ATTORNEYS Id1007/015 chosen so that no more than 300,6 and if possible only 10% of the weight of the runner (65 to 75 kg for example) for which shoe 1 is designed Is sufficient to press pivoting element 18 against stop surface 16.
When pivoting element 18 strikes stop surface 1 S(see Figure 2), the area of sole 2 or of sole covering 11 that extends from pivot axis 20 to bali or toe area 8 is inclined upward and fonnrard relative to support 22 around pivot angle A. Sole covering 11, when pivoting element 18 is bent away, has an obtuse angle of nearly 18011 in the vicinity of pivot axis 20.
When pivoting element 18 strikes stop surface 1.5, the gentle placement process in heel area 6 is terminated and the load exerted on sole 2 by the foot of the runner is distributed approximately uniformiy over the entire length of sole 2. As a resuit, and because of the momentum of the runner directed in the running din3ction, shoe 1 tips fonward around pivot axis 20 and rests its forward area of sole covering 11 on support 22.
This tilting of shoe I causes the foot and lower leg of the runner to be dispieced slightly forward in the running direcUon and the knee is bent slightly between the lower leg and upper leg. The maximum load on the foot or on sole 2 appears only after shoe I has tilted or after the runner's knee has bent so that the recoil produced by the impact on support 22 encounters a leg that Is already bent at the knee and which can accept the impact load In a gentle manner with elastic flexibility by means of the knee Joint with its skeleton and muscies, Shoe 1 according to the present invention thus Causes automatic roiling of the foot when running so that by comparison with conventional shoes, a considerably more protective transmission of the impact load to the body is produced.
A second embodiment of the shoe according to the present invention is shown In Figure 3. This shoe I essentially corresponds to the shoe I described above;

Shoe 1 according to Figure 3, in wedge-shaped recess 13, has a material element in the form of a material vwedge 25 made of an open-pored foam. This material wedge 25 !s mounted on stop surface 15 of sole body 10 and on pivoting element 18 by means of a glued connection.
Sole covering 11- is divided by a siit 27 in the area of pivot axis 20. The frameworh of the invention, of course, includes an embodiment without a siit (see for example the fourth embodiment of the present invention shown in Figures 5 and 6).
Advantageously, sole covering 11 is flexible In the vicinity of pivot axis 20 and formed by a taper since, in this embodiment of shoe 1, it Is advantageous that during the setting down phase of shoe I on support 22 in heel. area 6, the restoring force of pivoting element 18 is applied if possible only by material wedge 25 in order to ensure that shoe I is set down on support 22 as softly as possible.
A reinforcing piato 29 is placed In sole body 10 that extends from the iengthwise center of shoe I to rear heel area 6. The reinforcing plate 29 consists of a metal plate or a fiber-reinforced plastic plate and is located at a distance above a pressure distribution part 16, with reinforcing plate 29 being adapted to the curvature of pressure distributing part 16. The reinforcing plate 29 extends In the transverse direction over nearly three-fifths to four-fifths of the width of shoe I
and during the set-down phase during which pivoting element 18 is pressed ag?inst stop surface 15, that sole body 10 cannot be tilted downward by the heel.
15/02 2005 TUE 11:35 FAX ANWAr;L'1'E/A'171'UItNbYS 4qjUUH/Ulo g A third embodiment of*the invention is shown in_Figure 4. This. shoe I has essentially the same structure as shoe I described above; accordingly, the same or similar oomponents have identical reference numerals.
The wedge-shaped recess between stop surface 15 and pivoting element 18 Is enclosed by an air bellows 31. Two holes 32 are made in sole body 10, said holes terminating at one end at stop surface 15 and at the other end externally on sole body. 10.
A valve 33 is placed In each of the two holes 32 which limits the escap of air from air beHows 31 to the outside so that when pivoting element 18 is pressed toward stop surface 15 by the limited escape of air during the pivoting movement of pivoting element 18, a predetermined reiativeiy gentle resistance is offered in opposition.
When the pressure by vvhich pivoting element 18 is pressed against stop surface 15 is reieased, pivoting eiement 18 again pivots into the initiai position vvhich runs as a straight line extension of the rest of sole covering 11, whereupon vaives open and permit a rapid flow of air into air bellows 31.
Pivoting element 18 of sole covering 1'! is made In one piece with the rest of sole ' covering 11 and has a certain degree of dimensional stabiiity or flexurai strength so that it automatically pivots back into the initial position following compression of air bellows 31.
The fourth embodiment according to Figure 5 essentially corresponds to the second embodiment according to Figure 3, with the only difference being that recess 13 is not wedge-shaped but essentialiy in the form of a circular section and is filled with a-matQriai element 25 made of open-pored plastic.
