Description

Walking aid for shoes, shoe system with a shoe and a walker and system of a walker and a stick

The present invention relates to a walking aid, in particular for shoes with a solid sole, wherein the walker has a base body for releasable attachment to the sole and at least one fastening means for releasable attachment to a shoe. Furthermore, the present invention relates to a shoe system with a shoe, in particular with a solid sole, and a walker for releasable attachment to the shoe. Moreover, the present invention relates to a system comprising a walker and a stick. For different operations and different requirements, it makes sense to use special shoes. In the case of said special shoes, properties may occur which, on the one hand, are desired for the respective operation or requirement, may be disadvantageous when the shoe is used outside the respective operation or apart from the respective situation generating the requirement.

For example, the shoes may have a solid or rigid sole. For example, such shoes are not exclusively used in alpine sports, especially when skiing. The shoes are optimized for the particular use, ie for a combination with a ski binding and a ski, but are associated with the use without ski and ski binding with corresponding disadvantages. Hereinafter, the present invention will be described primarily with reference to shoes with a solid sole, as used for example in skiing. However, the articles of the present invention are by no means limited or limited to such shoes or for use in such shoes. Rather, the description is used in connection with ski boots to illustrate and clarify the invention.

For the said shoes, in particular for shoes with a firm sole, there has always been the problem that running in such shoes is difficult. In addition, depending on the design of the shoe can be added that even when standing in the shoes an unnatural posture, especially an unnatural attitude of the legs is caused. The latter is the case, for example, with ski boots, in which the movement of the ankle and thus the relative alignment between the foot and lower leg is limited. Furthermore, especially shoes with a solid sole have the disadvantage that walking on stairs or the Execution of similar movements are difficult and under sometimes significantly increased risk of falling are possible.

These disadvantages have in the past led to the development of walking aids, which are sometimes provided for releasable attachment to a shoe. The previous solutions have usually solved one of the above problems, whereas other problems persisted or even worsened. For example, the device of the disclosure US 4,045,809 B is suitable for facilitating unrolling with a shoe with a fixed sole and thereby facilitating walking, on the other hand the device disclosed therein makes the use of stairs considerably more difficult and even increases the risk of injury in use a staircase. Although the device disclosed in US 2011/0258882 A1 allows safe use of stairs and improves the rolling behavior, but does not cause the unnatural attitude of the legs or ankle is improved or corrected in the state. Comparable devices each solving part of the above-mentioned problems are known from the following references: US 2012/0117829 A1, DE 20 2006 002 533 U1, DE 1999/59353 A1, US 4,774,775 B, US 4,461, 104 B, DE 25 41 638 A1, DE 26 55 564 A1, DE 26 49 296 A1 and DE 2 314 847 A1.

Against this background, the present invention sets forth the task of overcoming the disadvantages of the devices of the state of the art. In particular, the object of the present invention is to propose a walker, a shoe system and a system of a walker and a stick, which each allow an improvement in comfort and safety. This object is achieved in a walker of the type mentioned gel ö stems that the main body is designed such that it extends to an attachment to the shoe of a toe only up to 40% of a sole length of the sole.

Surprisingly, it has been found that in a body extending from the top of the sole up to 40% of the sole length, at the same time facilitates the rolling and thus walking, improves the state and at least not safety in the use of stairs and similar obstacles is negatively influenced. In addition, the execution of the body with a length extending from the toe up to a maximum of 40% of the sole length, leads to an extremely compact walker. This has the advantage that the walking aid according to the invention, which is only temporarily arranged on a shoe and designed accordingly detachable, can carry or stow particularly space-saving, especially when the walker is not arranged on the shoe.

According to a first advantageous development, it can be provided that, when the walking aid is attached to the shoe, the main body extends from the toe to a maximum length of 35% of the sole length. As a result, the walker can be made even more compact, without affecting the beneficial effect on walking and standing, safety in stair use and the like with a provided with the walker shoe is adversely affected.

Most preferably, it can be provided that the walking aid, in particular the length of the body of the walker is designed for the shoe interior. Because the sole length is an extremely important measure for the dimensioning of the body. In particular, in order to achieve optimum gapping properties, however, it is also important to know where and how the foot of a user of a shoe in the shoe and in relation to the sole is attached. is ordered. Accordingly, it is provided according to a further, particularly preferred embodiment of the invention that the base body is designed such that it extends to a position of the sole, over which the toe base joint of a foot located in the shoe is arranged. Since the toe joint during walking without restriction by a shoe forms the decisive point when rolling the foot, by the extension of the body from the toe to a position of the sole, over which the toe joint of a foot located in the shoe is arranged, a particularly effective and natural abrasion can be achieved. It can be particularly preferably provided that the base body is designed such that the fulcrum of the body, which arises when rolling over the walker, is located slightly behind the center of the joint of the toe base joint of a foot located correspondingly in the shoe.

Most preferably, the walker is equally suitable for placement on a right shoe as on a left shoe. For this purpose, for example, be provided that the walker is symmetrical to a longitudinal axis of the walker. This facilitates the arrangement of the walker or assistants on a shoe or a pair of shoes, since no assignment of a walker must be made to each shoe, but each walker can be arranged on each shoe.

A further embodiment of the walker provides that the base body has a bottom support surface and is wedge-shaped, so that when attached to the shoe with increasing distance from the toe, a greater distance between the sole and the bottom support surface is generated. About the wedge shape of the body, the position of the legs, in particular the position of the lower leg when standing, can be influenced in a corresponding shoe. This is particularly advantageous if, with the use of the shoe, a limitation of Agility of the ankle is accompanied, which restricts or restricts the alignment between foot and lower leg. Also, a particularly uniform rolling can be achieved on the wedge-shaped configuration of the body.

According to a further, particularly preferred embodiment, provision may be made for the base body to have recesses and webs on the surface facing away from the ground support surface. As a result, on the one hand, it can be achieved that the walking aid can be fastened or arranged even more securely on the shoe even when there is adhesion to the sole of the shoe. In addition, the weight of the walker can be reduced by the formation of webs and recesses on the surface facing away from the bottom surface of the base body. Further advantages that can be achieved by the respective configuration of the webs and recesses are described in more detail in the following embodiments of the walker according to the invention.

According to a preferred refinement, provision can be made for the webs and recesses to form a first and a second contact profile on the surface of the base body remote from the bottom support surface. Accordingly, the present invention also relates to a pair of walking aids, which have the inventive design of the body and beyond in the ground support surface facing away from the surface recesses and webs, which form a first and a second contact profile in each case a walker. This makes it possible that two walking aids are arranged according to each other so that each engage the webs of a first contact profile in the recesses of a second contact profile and vice versa. As a result, the pack size of the walking aids, in particular the pack size of a pair of walking aids, is particularly advantageously reduced, as far as the walking aids are not arranged on the shoe, but are detached from the shoe. In addition, it can be provided according to a further, particularly advantageous embodiment that the first contact profile is formed complementary to the second contact profile. Because by the complementary trained to each other contact profiles, the base body of the walking aids, at least partially engaged with each other, whereby the height of a pair of walking aids, which are at least partially engaged with each other, well below the height of two individual walking aids. The webs and recesses and / or the resulting at least partially engagement are configured and / or dimensioned in such a way that the engagement can be made manually and can be reversed and a clamping action is generated between the walking aids during an engagement via the webs and recesses, so that an unwanted loosening or separating the walking aids is avoided.

A further, particularly advantageous embodiment of the walking aids provides that the base body comprises a front part body and a rear part body. In connection with this embodiment, it should be pointed out that the extension according to the invention of the main body from the toe to a part of the sole length is related to the total length of the basic body, which in the present embodiment is formed by the front and the rear partial body. The design of the walker with a front and a rear body part has different advantages. For example, the front part of the body and the rear body part can be made of different materials, the choice of materials such that a secure arrangement or attachment of the walker on the shoe ensures while a simple and safe placement of the walker on the shoe and a safe and easy release of Walker from the shoe is possible. Further advantages of an embodiment of the body with a front body part and A rear part of the body is disclosed below with reference to further embodiments.

For example, it can be advantageously provided that the front part body and the rear part body can be folded into an unfolded configuration and into a folded configuration. As a result, the pack size of a single walker can be reduced in an advantageous manner in a state detached from the shoe. For this purpose, it may be provided that the front body part and the rear part body are transferred to the arrangement of the walker on the shoe in the unfolded configuration and transferred during transport of the walker before or after an arrangement on the shoe in the collapsed configuration and in the folded Configuration take a space-saving outer dimension or pack size.

A further, particularly advantageous embodiment provides that the part bodies have recesses and webs on the surface facing away from the bottom support surface. In this case, too, the recesses and webs of the partial bodies, that is to say of the front partial body and of the rear partial body of the basic body, can serve to ensure that the walking aid can be securely arranged on the shoe, even if there are still adhesions on the sole. Furthermore, the weight of the walking aid can be advantageously reduced by the formation of recesses in the surface facing away from the bottom support surface surface of the body part.

According to a further, particularly preferred embodiment can also be provided that, in particular in the front part of the body, the recesses extend at least partially to the bottom support surface. On the one hand, this has the advantage that a particularly high weight reduction of the walking aid can be achieved by the recesses extending up to the floor support surface. In addition, they can reach the ground Pad surface penetrating recesses in the body part, in particular in the front part of the body, serve as a profile or profiling of the ground support surface and thus increase safety both while standing and when walking with a shoe and a walker invention arranged thereon.

It can also be provided in a further embodiment of the walker with a front and a rear part body of the base body, that the recesses and webs in the front part body and the rear part body are formed so complementary to each other, that in a collapsed configuration of the part body, the recesses and webs at least sections are engaged with each other. This can significantly reduce the amount or pack size of the walker in the collapsed configuration. For then the webs of the front part of the body engage at least partially or at least partially in corresponding recesses in the rear part body and vice versa, thus reducing the pack size in the folded configuration compared to a configuration with no complementary profiling of the surfaces opposite the ground support surfaces.

The walker according to the invention should, in particular, if it is not arranged on the shoe, take a particularly compact form to be carried as well as possible and space-saving can. For this purpose, a further advantageous embodiment provides that the front part body and the rear part body are connected to each other via a double joint. By using a double joint, a transport position, for example in the form of the folded configuration of the two body parts, can be achieved, which is particularly space-saving. According to a further, particularly preferred embodiment of the walking aid it can be provided that at least one fastening means is designed as an elastic fastening means, in particular as a tension band.

This allows a simple and safe placement and a simple and safe release of the walker on the shoe or the shoe can be achieved. Particularly preferably, the elastic fastening means can serve for fastening the walking aid in the heel region of the shoe.

In accordance with a further, particularly preferred embodiment, provision may additionally be made for the elastic fastening means to be designed in such a way that it makes possible both the fastening of the walking aid to the shoe and the securing of the walking aid in a collapsed configuration. Such a configuration has several advantages. On the one hand, the use of the elastic fastener to secure the walker in the collapsed configuration ensures that the walker remains in the collapsed configuration until the elastic fastener is released and thereby the collapsed configuration or retention in the collapsed configuration is released. On the other hand, can be achieved by the double use of elastic see fastening means for attaching the walker to the shoe on the one hand and to secure the walker in the folded configuration on the other hand, a further reduction of the packaging dimensions of the walker in the folded configuration, since it largely prevents the elastic attachment means in the folded configuration protrudes from the walker.

A further, particularly advantageous embodiment of the walker provides that the ground support surface has a profile and at least one profile recess has, which is adapted for at least partially receiving a stick, in particular a ski or walking stick. The corresponding recess on a surface of the walker can be special can be advantageously used to attach the walker to a stick when it is not placed on the shoe, but is detached from the shoe. This facilitates the transport of the walker in the form released by the shoe. At the same time, as part of the profile of the ground support surface, the profile recess can also realize a profile function of a sole profile in an arrangement of the walker on a shoe and thus improve the safety of the user of the walker in an arrangement on a shoe.

A particularly preferred embodiment of the walker provides that the elastic fastening means when securing the walker in the collapsed configuration, the walker, in particular on an outer contour formed at least partially by the bottom support surface, at least fully encloses. As a result, a particularly effective securing of the walker in the collapsed configuration can be achieved. In addition, this can be particularly advantageously arranged or clamped on the outer circumference or on the outer contour of the walker in the collapsed configuration, the elastic fastening means, so that the elastic fastening means does not protrude from the walker and thus takes up additional space.

Further, according to a preferred embodiment of the walker be provided that the elastic fastening means is designed so that, especially in securing the walker by the fastening means in the folded configuration, the inclusion of a stick, especially a ski or walking stick, in and / or secured to a profile recess. This embodiment of the fastening means thus relates, as well as the backup already described above in the folded configuration with the fastening means, a respective second or further use of the fastening means in addition to the detachable attachment of the walker to a shoe. This multiple substitutability the fastener leads to a particularly advantageous usability of the walker both in the arrangement of a shoe as well as before or after the arrangement of a shoe. In a shoe system with a shoe, in particular with a solid sole, and a walker for releasable attachment to the shoe, the abovementioned object is achieved in that the walking aid is designed according to one of the previously described embodiments. As a result, the advantages already described with reference to the individual embodiments of the walking aid can also be realized for the shoe system. It can not only produce beneficial effects when the walker is placed on the shoe. The compact design and further advantages of the above-described embodiments of the walking aid can also be realized if the walking aid is not arranged on the shoe.

A particularly preferred embodiment of the shoe system provides that a solid sole at least partially has a sole profile and facing away from the bottom support surface of the walker surface has a contact profile, wherein the sole profile and the contact profile are at least partially complementary to each other. The complementary configuration of the contact profile and the sole profile are to be provided in particular in the area in which the walker comes to rest on the shoe, in particular on the sole of the shoe, when the walker is arranged or arranged on the shoe. Due to the mutually complementary configuration of the contact profile and the sole profile, a particularly secure arrangement of the walker can be achieved on the shoe. The contact profile of the walking aid can be formed by the above-described webs and recesses of the main body or the partial body of the main body. For the sake of completeness, it should be mentioned at this point that the contact profile described above need not be the same type of profile as described above with reference to the first and second contact profile. The present contact profile is arranged at least on the side facing away from the ground support surface surface of the walker and cooperates with a sole profile of a shoe. The contact profile described above is formed at least on the ground contact surface and is primarily used for releasable connection or coupling of two walking aids each other or to each other. This makes it clear that both types of contact profiles in each case facilitate or convey contact with another object, but the other object with which the contact is made can be designed differently and thus the arrangement of the contact profile on or on the walking aid can also be different ,

In the case of a system comprising a walking aid and a stick, in particular a ski or walking stick, the above formulated article is displaced by a coupling device to releasably fix the walking aid to the stick.

Particularly preferably, the walking aid and the coupling device can have complementary coupling elements. Advantageously, the coupling elements are designed so that a releasable coupling between the coupling device and the walking aid can be achieved.

In addition, it can be advantageously provided that the coupling device can be attached to the floor. The corresponding system of walker and floor allows in particular on the complementary coupling elements that the walker safely attached to the stick and can be solved quickly and safely from the stick to assemble or arrange on a shoe.

The coupling devices can also be formed by the stick itself.

According to an advantageous development, it can be provided that the walking aid has the features described above and thereby realizes the corresponding advantages.

Further advantages and details of the invention are explained below with reference to the exemplary embodiments illustrated in the drawings. 1 shows an exploded view of a walking aid according to the invention in accordance with a first embodiment;

8 shows a system according to the invention, according to a first embodiment.

1 shows a walking aid 01 according to the invention, in which the main body 02 has a front part body 02.1 and a rear part body 02.2. The walking aid 01 also comprises two attachment means 03. One of the attachment means 03 is designed as an elastic attachment means 03.2 in the form of a tension band, which is attached to the rear part of the body 02.2. The second attachment means 03 is arranged on the front part body 02.1 and is realized by a rigid attachment means 03.1.

Via the attachment means 03, the walking aid 01 can be detachably arranged on a sole of a shoe, in particular on a rigid sole of a shoe. For this purpose, the toe is brought into engagement with the first fastener 03.1. Accordingly, the fastener 03.1 is also designed similar to a corresponding shoe tip recording a ski binding. To the heel of the shoe, the second fastener 03 is stretched in the form of elastic fastener 03.2. As a result, a force is generated which holds the walker 01 securely on the sole of the shoe, as long as the attachment means 03.2 is placed around the heel of the shoe. In the case of a ski boot, the heel supernatant of the shoe which otherwise engages in the heel part of the ski binding securely secures the elastic fastening means and thus the walking aid to the shoe. The partial body 02.1 and 02.2 of the main body 02 are connected to each other via two double joints 04, which engage in corresponding bearings 05 in the partial bodies 02.1, 02.2. The front Teilköper 02.1 may have a shell 02.3 and a lower part 02.4, which consist of different materials. The choice of material can be made so that for the upper part 02.3 optimum hold between shoe and mate 01 and 02.4 for the lower part of an optimal grip on different surfaces can be achieved. The upper part 02.3 and the lower part 02.4, for example, glued together or otherwise connected to each other. The double joints 04 allow the front body 02.1 and the rear body 02.2 to be folded from an unfolded configuration into a collapsed configuration. The corresponding transfer between the two configurations of the partial bodies will be explained in more detail with reference to FIGS. 3a to 3c.

The main body 02 according to the present invention has a total length L which extends from the toe up to a maximum of 40% of the length of a sole of a shoe on which the walking aid is placed. Particularly preferably, the total length L of the body 02 extends from a toe up to max. 35% of the sole length of the shoe. The length L is, of course, the length of the walking aid 01 in an assembled state and not the length in the state of the exploded drawing of FIG. 1.

Accordingly, it can be provided according to an embodiment of the invention that the total length of the body with a sole length of 335 mm has a length of 1 15 mm and the body in the arrangement of the walker on a shoe starting from the toe over the front 15 mm the shoe sole extends. By this dimension of the length of the main body, measured from the toe or sole tip, it can be achieved that the main body extends to a position P of the sole of the shoe, over which the toe base joint of a foot located in the shoe is arranged. As a result, in particular the unwinding with the aid of the walking aid according to the invention can be significantly improved.

The rear part body 02.2 also has two channels 24, which each form two channel openings 23.1, 23.2. Via the channels 24, the second attachment means 03.2 be attached to the body, in particular to the rear Teilköper. For this purpose, the second fastening means may for example have end sections 25 with an enlarged diameter, wherein the diameter of the end sections 25 is greater than the diameter of the smaller channel openings 23.2 and smaller than the diameter of the larger channel openings 23.1 of the channel 24. Thus, the end sections 25 at least partially taken up by the channels 24 and secured there. The weight of a walking aid according to the invention is preferably less than 120 g, more preferably less than 100 g. Thus, the walker next to a small pack size and a low weight.

Further explanations regarding the dimensioning and design of the body 02 of the walker 01 will be described below with reference to FIG. 2.

In the side view of FIG. 2, it can be seen that the base body 02, with its bottom support surface 06 and the surface 07 facing away from the bottom support surface 06, forms a wedge shape which, when the walker 01 is fastened to a shoe not shown in FIG. 2 causes that with increasing distance from the toe a greater distance between the sole not shown in FIG. 2 and the ground support surface 06 is generated. The wedge-shaped design of the body 02, the unwinding is facilitated.

In addition, the maximum height H of the wedge-shaped basic body 02 can be used to set or change the position of the shoe when standing and restricting the movement of the ankle through the shoe and also to adjust the entire posture when standing in a corresponding shoe. This means that over the maximum height H of the body 02, the walker 01 can improve the safety and comfort in the state. 2, it can be seen that the main body 02, starting from a toe or tip of a shoe sole, extends up to a position P of the sole, not shown, above which the toe base joint of a foot located in the shoe is arranged. For this purpose, the main body extends from the toe or toe of the shoe sole, starting from a maximum of 40%, particularly preferably over a maximum of 35%, of the sole length of the shoe. In the illustration of Fig. 2 it can also be seen that the main body extends on the bottom support surface up to a position P 'which lies slightly behind the position of the sole, over which the toe base joint of a foot located in the shoe is arranged. This makes it possible for the fulcrum point 08, which is to be overcome when rolling over the walker 01, to be slightly behind the center of the joint of the toe base joint of a foot located in the shoe. As a result, the rolling and running with the help of the walker is further improved.

With reference to FIGS. 3 a to 3 c, inter alia, the function of the double hinges 04 in conjunction with the front part body 02. 1 and the rear part body 02. 2 as well as the configuration of the part bodies 02 02.2 explained. Fig. 3a shows the walker 01 in an unfolded configuration K1. The unfolded configuration K1 represents the configuration in which walker 01 can be placed on a shoe or attached to a shoe. It can clearly be seen from the illustration of FIG. 3 a that both the front part body 02. 1 and the rear part body 02. 2 each have webs 10 and recesses 11 arranged between the webs. In the case of the front part body 02.1, it is also provided that at least part of the recesses 11 extend from the surface 07 remote from the bottom support surface 06 to the bottom support surface 06, which on the one hand improves the profiling of the bottom support surface 06 and on the other hand makes the weight of the walker 01 advantageous reduced.

In the exemplary representation of FIG. 3 a, it can already be anticipated that the webs 10 and recesses 11 of the front part body 02. 1 and the rear part body 02. 2 arranged on the surface 07 facing away from the ground support surface 06 are at least partially complementary to one another, so that in one folded configuration, as shown in Fig. 3c, the respective webs 10 of the rear part of the body 02.2 with corresponding recesses 11 of the front body part 02.1 are at least partially engaged with each other. The same applies, of course, vice versa for the webs 10 of the front part of the body 02.1 and the recesses 11 of the rear part of the body 02.2. Corresponding recess web pairs 12.1, 12.2 and 12.3 are highlighted by way of example in the illustration of FIG. 3b.

3a and 3b can be seen particularly well a securing means 13, which in conjunction with the elastic fastening means 03.2 secures the securing of the walking aid in the folded configuration K2 shown in FIG. 3c. For this purpose, the elastic fastening means 03.2 in the collapsed configuration K2 shown in FIG. 3c, starting from the rear part body 02.2, around the led front part of body 02.1, wherein the bottom support surface 06 of the front body part 02.1 corresponding guide recesses 14 has. The guide recesses 14 can simultaneously serve as a profile of the bottom support surface 06. The elastic fastening means is then placed around the rear part of the body 02.2, to which also the rear part of the body in Fig. 3c unrecognizable guide recesses 14 may have (see Fig .. 7). Subsequently, the elastic fastening means 03.2 is guided around the securing means 13. Here, the length of the elastic fastening means 03.2, as well as its elastic properties is designed so that when enclosing the walker 01 in the folded configuration K2, as shown in the illustration of Fig. 3c, on the outer contour of the folded walker 01, the elastic fastening means undergoes an extension, that is to say an elastic deformation. This ensures that by an additional or further elastic deformation of the elastic fastening means 03.2 the fastener 03.2 released from the securing means 13 and the backup of the walker 01 in the folded configuration K2 can be lifted by the elastic fastening means 03.2. Equally, it can be ensured by the elastic deformation that the elastic fastening means 03.2 secures the walker 01 in the folded configuration K2 when securing to the securing means 13. In addition, it can be seen in FIGS. 3a to 3c that the rigid fastening means 03.1 comprises a projection 26 which, for example, is brought into contact with an upper side of a projection of a ski boot in order to fix or arrange the walker 01 on the ski boot. In addition, the elastic fastening means 03.2 is provided with a grip element 28. The grip element is used for manual actuation, in particular for manual elastic stretching, of the elastic attachment means 03.2. The grip element may be formed of textile material and connected to the attachment means 03.2. In order to achieve a particularly compact shape or particularly compact pack size in the folded configuration K2 of the walking aid 01, it can be provided that the protrusion 26 of the rigid fastening means 03.1 has a recess 27 arranged on an upper side of the protrusion, of which, in the folded configuration K2 of FIG Walker 01, the handle member 28 of the elastic fastener 03.2 is at least partially received, as it is indicated for example in Fig. 3c. In this way, the recess 27 makes it possible, with an arrangement of the elastic fastening means 03.2 on the securing means 13 for securing the walking aid 01 in the folded configuration K2, to grip the grip element 28 closely against the walking aid 01 and, at the same time, to reach it easily. The gripping element 28 is, as shown in FIG. 3c, in this case preferably configured such that it projects beyond the front part body 02.1 and in particular via the rigid attachment means 03.1 when partially accommodated in the recess 27 in the folded configuration K2 of the walking aid 01. Thus, the handle member 28 can be easily operated at an arrangement of the elastic fastening means 03.2 on the securing means 13. The grip element 28 is thus easily accessible even in the folded configuration K2, in order to release the securing of the walker 01 in the folded configuration K2. In the plan view of Fig. 4 facing away from the bottom support surface 06 surface 07 is shown. In FIG. 4, as well as in FIGS. 5 and 6, the walker according to the invention without the second attachment means is shown for reasons of clarity. As can be seen from FIG. 4, the surface 07 comprises a knobbed structure 15. The knob structure 15 serves to prevent slippage of the walking aid 01 in relation to a shoe not shown in FIG. 4. Alternative or additional However, in addition to the nub structure 15, the surface 07 may also form a contact profile, which is designed such that it is complementary to a sole profile of the shoe, on which the walker 01 is detachably arranged. This has the particular advantage that in combination with a shoe having a corresponding sole profile, a particularly good hold of the walking aid can be achieved in an arrangement on the shoe. By a corresponding design of a contact profile and a sole profile, a shoe system can be realized in a particularly advantageous manner, in which the walking aid is tailored to the shoe. In addition, a particularly advantageous power transmission between shoe and walker can be realized by the realization of complementary sole profiles and contact profiles on the part of the shoe and on the part of the walker. 5, in the rear view of the walker 01 again the securing means 13 and the trained on the bottom support 06 of the rear part body 02.2 guide recesses 14 can be seen, which allow that for reasons of clarity in Fig. 5, not shown elastic fastening means at enclosing the outer contour of the walker in a collapsed configuration to secure the

Walker in the folded configuration is used. The guide recesses facilitate the guidance of the elastic fastening means along the bottom support surface 06. FIG. 5 further shows the channel openings 23.2 of the channels 24 in which the second fastening means not shown in FIG. 5 can be guided and secured.

In the illustration of FIG. 6, a walker 01 is shown with a view of the ground support surface 06. The bottom support surface 06 has, in addition to the guide recesses 14 in the front part of the body 02.1 and 02.2 in the rear part of a profile 16. In this case, the profile 16 comprises a profile recess 17, which is used for at least partially accommodating a cane, in particular special of a ski or walking stick, is set up. According to the embodiment of FIG. 6, the profile recess 17 extends substantially perpendicular to the longitudinal direction of the base body. The profile recess 17 preferably has a shape of a circle segment (cf., Fig. 2) and is accordingly formed as a cylinder segment. In principle, the profile recess 17 can also be formed on another surface of the walker 01. When training on the bottom support surface 06, so in training as part of a profile 16 of the bottom support surface 06, however, there is the advantage that the profile recess 17 at the same time as a profile of the walker 01 in the arrangement of the walker 01 on a shoe and thus to increase safety during standing and walking using a walking aid 01 serves, and the profile recess 17 can be used to receive a part of a stick, whereby the attachment of the walker to a stick, in particular in the folded configuration shown in Fig. 3c K2 of the walker 01 is facilitated.

In an arrangement of the walker on a stick, in particular in the folded configuration K2, in addition to the profile recess 17, the elastic attachment means 03.2 can be used particularly advantageous since, as already described with reference to Fig. 3c, in the folded configuration K2 the walker 01 the elastic attachment means 03.2, preferably along the guide recesses 14 on the outer contour of the walker 01, so on the bottom support surface 06 of the walker 01 the walker 01 can fully enclose to secure the walker 01 in the folded configuration K2. In this embodiment, however, the elastic fastening means can simultaneously serve to secure or attach the walker 01 to a floor, since a corresponding floor is pressed by the elastic fastening means 03.2 in the profile recess 17 and held there. It is further advantageously realized that when removing the elastic fastening means 03.2 from the securing means 13 is not only the backup of the walker 01 in the folded configuration is repealed, but at the same time the backup or attachment of the walker 01 is lifted or released on the floor.

FIG. 7 shows a system according to the invention comprising a walker 01, which is illustrated in an exploded view on the basis of the illustration of FIG. 1, and a floor 18, which is shown only in sections in the illustration of FIG. In addition to the stick 18 and the walking aid 01, the system comprises a coupling device 19 for releasably securing the walker 01 to the stick 18. The coupling device 19 comprises a clamp 20 which can be fastened to the floor 18 with a fastening means, not shown in FIG. 7, for example in the form of a screw. The coupling device 19 additionally comprises a coupling element 21, which can be releasably connected to a complementary coupling element 22 of the walking aid. For example, FIG. 7 shows in the region of the profile recess 17 a coupling element 22 complementary to the coupling element 21 of the coupling device 19. In FIG. 7 the coupling element 21 is designed as a ball head, for example, with the coupling element 22 of the walking aid 01 according to the principle of a push-button connection interacts.

FIG. 8 likewise shows a system comprising a walking aid 01, a pole 18 and a coupling device 19, wherein the walking aid 01 in the example of FIG. 8 is still shown in the unfolded configuration K2. For a safe and space-saving transport it can be provided that also the system shown in FIG. 8 for transporting the walker 01 away from a shoe is transferred into the folded configuration K2.
