Description

The present invention relates to an overshoe for a shoe according to claim 1. In principle, overshoes for shoes are known. For example, US Patent 10,299,532 B2 discloses an overshoe for a shoe that has a sole, a front edge, a front edge cover adjoining the front edge, and a shaft adjoining the front edge cover. The shaft has a first shaft section and a second shaft section, each extending from an upper edge of the shoe to a lower edge adjacent to the sole, and separated from each other by a gap extending from the upper edge to the lower edge of the shoe in a heel area of ​​the overshoe. Furthermore, the known overshoe has a shaft front section located on a region of the shaft opposite the gap, and a fastening means designed to detachably attach the overlapping section to the shaft.To heat this overshoe, a heating element designed as a heat pack is attached to an insole, which is then inserted into the overshoe. This overshoe, known from US patent 10,299,532 B2, has the disadvantage that adjustable and controlled heat output to a shoe inside it is not possible. Furthermore, the heating element in the overshoe can only be replaced if the insole is completely removed. This is inconvenient and time-consuming. An overshoe incorporating an electric heating element is known from US Patent 2006 / 0248747A1. The overshoe consists of a flexible, flat structure equipped with heating wires and is pulled over the front edges and the adjacent toe cap of a shoe. Thus, one surface of the overshoe is positioned adjacent to the shoe, while its opposite surface is disadvantageously exposed to the elements. The overshoe is attached to the shoe by a strap spanning the sole and a fastening device located in the heel area. Due to this design, the overshoe known from US 2006 / 0248747A1 is disadvantageously unstable. From US patent 2004 / 0159011A1, an overshoe is known, comprising a sole, a toe edge, a toe edge cover adjoining the toe edge, and a shaft adjoining the toe edge cover. The overshoe is permanently closed at the heel end. Opposite the heel end, on the midfoot side, the overshoe has a closable opening through which a shoe on a foot can be inserted into the overshoe. For thermal insulation, the known overshoe contains heat-reflective layers that reflect body heat transferred from the foot, through the shoe, into the overshoe. Due to the design of the overshoe known from US patent 2004 / 0159011A1, quick insertion and removal of a shoe from the overshoe are not feasible.Furthermore, the well-known overshoe has the disadvantage that adjustable and controlled heat emission to a shoe located inside it is not feasible. US Patent 2,108,650 A discloses an overshoe comprising a sole, a toe edge, a toe edge cover adjoining the toe edge, and a shaft adjoining the toe edge cover. The overshoe is permanently closed at the heel end. At the ankle end, the overshoe has a closable opening through which a shoe can be inserted. No special thermal insulation is disclosed in US Patent 2,108,650 A. Due to the design of this known overshoe, quick insertion and removal of a shoe are not feasible. Furthermore, adjustable and controlled heat dissipation to a shoe inside the overshoe is not possible with this known overshoe. US patent 4,665,301 A discloses a battery-heated insole with heat-conducting layers that can be inserted directly into a shoe. Information on how the heating of the insole is controlled is not provided in US patent 4,665,301 A. From KR 10 2022 0 145 939 A, an overshoe equipped with electric heating elements is known. However, this overshoe has no sole, so that no heating of a shoe inside the overshoe is possible in its lower area. This is all the more disadvantageous because this area has a large thermal surface area adjacent to the cold floor. Finally, an overshoe is known from DE 10 2009 033 142 A1 and the WO 2011 / 006 481 A1 based thereon, comprising: - a sole, - a front edge, - a front edge cover adjoining the front edge, and - a shaft adjoining the front edge cover with a first shaft section and a second shaft section, each extending from an upper shoe edge to a lower shoe edge adjacent to the sole and separated from each other by a gap extending from the upper shoe edge to the lower shoe edge in a heel area of ​​the overshoe, - a shaft front section located on a region of the shaft opposite the gap, - an overlap section located on one of the two shaft sections and extending from the upper shoe edge to the lower shoe edge, selectively closing the gap or opening it.and at least one fastening device attached to the shaft, designed to detachably fasten the overlap section to the shaft. The transfer of heat from the overshoe known from DE 10 2009 033 142 A1 and WO 2011 / 006 481 A1 to a shoe inside it is not intended. Therefore, controlled heating of the shoe in a detrimental way is not possible. Furthermore, due to its design, quick insertion of the shoe into and quick removal of the shoe from the overshoe is not practically possible. The object of the present invention is to provide an overshoe that can be put on and taken off easily and quickly by a person wearing it, and in which controlled heat transfer to the shoe is efficient. The problem is solved according to the invention by the features of claim 1. Further embodiments of the invention are set forth in the dependent claims. The overshoe according to the invention is designed to accommodate a shoe worn by a person and comprises: - a sole, - a front edge, - a front edge cover adjoining the front edge, and - a shaft adjoining the front edge cover with a first shaft section and a second shaft section, each extending from an upper shoe edge to a lower shoe edge adjacent to the sole and separated from each other by a gap extending from the upper shoe edge to the lower shoe edge in a heel area of ​​the overshoe, - a shaft front section located on a region of the shaft opposite the gap, - an overlap section located on one of the two shaft sections and extending from the upper shoe edge to the lower shoe edge, selectively closing the gap or opening it.and at least one fastening device attached to the shaft, designed to detachably fasten the overlap section to the shaft. The overshoe according to the invention is characterized in that: - the overlap section has a first overlap section extending from the upper edge of the shoe to a first end region located away from the sole, wherein the distance of the outer edge of the first overlap section from an edge of the first shaft section or the second shaft section opposite the front edge increases up to the first end region; - the overlap section has a second overlap section extending from the first end region to a second end region adjacent to the sole, wherein the distance of the outer edge of the second overlap section from the edge of the first shaft section or the second shaft section opposite the front edge decreases up to the second end region; - the overlap section is configuredto at least partially cover the front section of the shaft when the overshoe is closed, - at least one heating element is located at least partially on the front edge cover, at least partially on the sole, at least partially on the first shaft section and / or at least partially on the second shaft section, - at least one energy storage device is provided that supplies the at least one heating element with electrical energy at least temporarily, and - at least one operating device is operatively connected to the at least one heating element and / or the at least one storage device. In other words, the overshoe according to the invention is designed such that it can accommodate a shoe worn by a person. This shoe can be designed in any suitable way. Advantageously, it can be a football boot. The overshoe has a sole. This sole is designed in any suitable way. Advantageously, it may have a first, outer side, which, when the overshoe is in contact with a surface such as soil, grass, concrete, or the like, can be considered the outsole of the overshoe. Preferably, this outer side of the sole has a profile and / or lugs to make the overshoe slip-resistant, in particular, on its contact surface. Furthermore, the sole has a second, inner side, which faces the interior of the overshoe and can be considered the insole of the overshoe. Thus, the sole of a shoe inside the overshoe rests against the inner side of the overshoe's sole. Preferably, the inner side of the overshoe's sole is designed to be complementary to the sole of the shoe inside it.In particular, recesses can advantageously be provided on the inner side of the overshoe's sole to accommodate projections of the sole of the shoe inside the overshoe, especially treads and / or lugs. Alternatively, the inner side of the overshoe can preferably be substantially smooth to facilitate quick removal of the shoe from the overshoe. The sole can be made of any suitable material or material composite. For example, the sole can be made of a plastic, a plastic composite, leather, rubber, and / or latex. Preferably, the sole is waterproof, at least on its outer side. The overshoe according to the invention further comprises a front edge that limits its front region both outwards and inwards. The inner side of the front edge, i.e., the area of ​​the overshoe opposite the toe area of ​​a shoe held in the overshoe, preferably has a geometric shape that is essentially complementary to the front area of ​​the shoe held in the overshoe. Optionally, the inner side of the front edge of the overshoe may abut the outer surface of the shoe held in the overshoe. A front edge cover adjoins the front edge of the overshoe according to the invention, viewed in the direction of a heel area of ​​the overshoe. This cover extends across the entire width of the overshoe in the transverse direction. Thus, the front edge cover is located essentially in an area where the midfoot of a shoe, which in turn is enclosed in the overshoe, is positioned. The front edge cover of the overshoe according to the invention is adjoined by a shaft, viewed in the direction of a heel area of ​​the overshoe. The shaft has a first shaft section and a second shaft section, each extending from an upper edge of the overshoe to a lower edge adjacent to the sole and separated from each other by a gap extending substantially in a heel area of ​​the overshoe from the upper edge to the lower edge. Any one or all of the shaft sections can be made of any suitable material. In particular, it is possible to make one or each shaft section inherently rigid or flexible. In an area of ​​the upper opposite the gap, there is a toe section. In other words, the toe section faces the front edge of the overshoe. If the first and second upper sections are designed as separate elements on the overshoe, they are connected to each other via a fastener at the toe section, either detachably or permanently. A detachable connection is achieved, in particular, by a hook-and-loop fastener or a zipper. A permanent connection is achieved, in particular, by a material-bonded and / or form-fit connection of the two upper sections, especially by injection molding, an adhesive bond, or a weld. Alternatively, the first and second upper sections can be formed as a single piece in the area of ​​the toe section. The overshoe according to the invention additionally features an overlap section located on one of the two shaft sections, extending from the upper edge of the shoe to the lower edge, and selectively closing the gap or opening it. The overlap section can be made of any suitable material. In particular, it is possible to make the overlap section rigid or flexible. The length of the portion of the overlap section that is connected to the shaft section or formed integrally with it can be any suitable size. Thus, it is possible to extend this connection area between the overlap section and the shaft section over the entire length of the gap or only over a portion of the gap's length. In principle, the overlap section can be provided at any suitable location on the upper, particularly on the left or right side of the upper, or on a corresponding section of the upper. Thus, if the overshoe is designed to accommodate a right-hand shoe, the overlap section is advantageously positioned on the left-hand section of the upper, viewed from the heel area towards the front edge. In this case, when the overshoe, designated as a right-hand overshoe, is closed, a portion of the overlap section furthest from the left-hand section is attached to the right-hand section. It is advantageous for the overlap section to extend over the right-hand section and onto the left-hand section.If, however, the overshoe is designed to accommodate a left shoe, the overlap section is advantageously positioned on the right-hand shaft section when viewed from the heel area towards the front edge. In this case, when the overshoe, designated as the left-hand overshoe, is closed, a portion of the overlap section furthest from the right-hand shaft section is attached to the left-hand shaft section. Advantageously, the overlap section can be extended over the left-hand shaft section and onto the right-hand shaft section. Overall, this advantageously enables a simple and therefore quick closing and opening process for the overshoe according to the invention. The overshoe according to the invention has at least one fastening means attached to the upper, which is designed to detachably fasten the overlap section to the upper. The fastening means allows the overlap section to be detachably fastened to the upper. The detachable connection is achieved, in particular, by means of a hook-and-loop fastener, a hook-and-eye fastener, or a zipper. It is understood that the fastening means interacts with a corresponding element located on the overlap section. In particular, the overlap section and the upper can have elements of a hook-and-loop fastener that can be brought into contact with each other or detachably from each other.Alternatively or cumulatively, it is possible to provide at least one opening and / or at least one hook and / or at least one eyelet on the overlapping means, which interact with corresponding receiving means, in particular locking elements that engage positively into the opening, with eyelets corresponding to the hooks or with locking elements that engage into the eyelets. The overshoe according to the invention is characterized firstly by a special design of the overlap section: - The overlap section has a first overlap section that extends from the upper edge of the shoe to a first end region located away from the sole, wherein the distance of the outer edge of the first overlap section from an edge of the first shaft section or the second shaft section opposite the front edge increases up to the first end region. - The overlap section has a second overlap section that extends from the first end region to a second end region adjacent to the sole, wherein the distance of the outer edge of the second overlap section from the edge of the first shaft section or the second shaft section opposite the front edge decreases up to the second end region.- The overlap section is designed to at least partially cover the front section of the shaft when the overshoe is closed. This design advantageously creates an opening in the overshoe that is sufficiently large and accessible for inserting and removing a shoe. Furthermore, this advantageously allows for easy, and therefore quick and reliable, opening and closing of the overshoe. It should be noted that each shaft section can have the same stiffness. Alternatively, the shaft section containing the overlap section can be designed with a higher stiffness than the other shaft section. This advantageously allows the opening characteristics of the overshoe, in particular the shape and size of the opening for inserting and removing the shoe, to be determined. The overshoe according to the invention is further characterized in that at least one electrical heating element is located at least partially on the front edge cover, at least partially on the sole, at least partially on the first shaft section, and / or at least partially on the second shaft section. This advantageously enables heat transfer from the overshoe to the shoe contained within it, which occurs precisely in a desired location. The heat transfer medium itself comprises a flexible sheet structure, particularly in the form of a fabric or foam, or an inflexible sheet structure, particularly in the form of a rigid wall, in which at least one heating wire, and preferably at least one heating mat, is located. According to a preferred embodiment of the heat transfer medium, the heating wire is fixed to the sheet structure in a meandering pattern with a covering layer, particularly by means of embroidery thread. Alternatively or cumulatively, the heating wire or heating mat can be embedded or foamed into a flexible carrier foam of the sheet structure. Alternatively or cumulatively, the heat transfer medium comprises a number of electrically parallel-connected heating conductors that are attached to the sheet structure. The heating conductors consist of carbon fibers, a metal, or are designed as PTC heating elements. It should be noted that the surface structure can preferably be designed as a membrane which has spacers and pore-like openings on at least part of its surface adjacent to a shoe received in the overshoe in order to improve the heat transfer of the heating wire, heating mat or heating conductor to the shoe. The at least one electrical heating element must be supplied with electrical energy. Therefore, according to the invention, at least one energy storage device is provided, which is designed as a battery, accumulator, or capacitor. The energy storage device is electrically connected to the heating element. It is designed to be removable from the overshoe or not removable. In a particularly advantageous embodiment, the accumulator is designed as a lithium-polymer accumulator, which, due to its malleability, can be readily adapted to the geometry of the overshoe that receives it. Furthermore, according to the invention, at least one operating means is provided which is operatively connected to the at least one heat medium and / or the at least one energy storage device in order to switch the heat medium on, off and / or otherwise bring about a change in the energy emitted by the heat medium. The overshoe according to the invention can be heated advantageously quickly, reliably and conveniently by means of the previously disclosed heating means, energy storage and operating means. Overall, this creates an overshoe that can be put on and taken off easily and quickly by the wearer, and in which controlled heat transfer to the shoe is efficient. According to a preferred embodiment of the overshoe according to the invention, the first overlapping section and / or the second overlapping section, when the overshoe is closed, extends at least partially beyond the gap and the front section of the shaft onto the shaft section that does not correspond to the shaft section on which the overlapping section is positioned. Thus, when the first overlapping section is positioned, i.e., arranged or attached, to the first shaft section, it can be moved across the gap onto the second shaft section and attached thereto. According to a particularly preferred embodiment, the first overlapping section can be extended further over the second shaft section onto the first shaft section. If, however, the first overlapping section is positioned, i.e., arranged or attached, to the second shaft section...If the second overlapping section is attached to the first shaft section, it can be moved across the gap onto the first shaft section and fastened there. Similarly, if the second overlapping section is positioned, i.e., arranged or attached, to the first shaft section, it can be moved across the gap onto the second shaft section and fastened there. Conversely, if the second overlapping section is positioned, i.e., arranged or attached, to the second shaft section, it can be moved across the gap onto the first shaft section and fastened there. According to a particularly preferred embodiment, the second overlapping section can be extended beyond the first shaft section and onto the first shaft section. Overall, this advantageously achieves a quick and effective closure of the overshoe in the shaft area. This closure can also be opened just as reliably and quickly. According to a further preferred embodiment of the overshoe according to the invention, the first overlap section and the second overlap section share a common tongue section. This tongue section is preferably located at the respective ends of the first and second overlap sections furthest from the shaft. The tongue section is preferably designed as a common end of the first and second overlap sections and extends from them. It is dimensioned such that it can be easily grasped by the fingers of one hand and positioned as previously disclosed, thereby advantageously facilitating the opening and closing of the overshoe. In principle, the energy storage device can be located at any suitable location within the overshoe or on an outer surface of the overshoe, either replaceably or non-replaceably. For example, it is conceivable to house the energy storage device in the sole area of ​​the overshoe, either replaceably or non-replaceably. However, according to a preferred embodiment of the overshoe according to the invention, a receiving element accessible from the outside of the overshoe is provided to accommodate the energy storage device. This can be designed, in particular, as a closable or non-closable pocket. This allows for easy replacement of the energy storage device. It should be noted that the overshoe can advantageously be provided with an electrical interface that is electrically connected to the electrical power source, in particular a battery storage device. The interface can be positioned at any suitable location on the overshoe. It is preferably accessible from the outside. This makes it possible, in particular, to supply electrical energy and / or electrical signals to the overshoe via the interface from a source located away from the overshoe, especially a battery charger. It should be noted that the electrical energy can also be supplied alternatively or cumulatively by induction. In principle, the at least one heat-generating element can be located at any suitable point on the overshoe. However, according to a preferred embodiment, the at least one heat-generating element extends at least partially from the front edge cover towards the heel area. Alternatively or cumulatively, the at least one heat-generating element is located at least partially in the first shaft section and / or the second shaft section. This advantageously allows heat to be released in specific areas or sections of the overshoe. This applies all the more if the at least one heating element has at least two zones with different heating capacities. It is advantageously possible to provide a first zone located in the area of ​​the overshoe adjacent to a shoe inside it. A second zone can be connected to the first zone, either directly adjacent to it or spaced apart from it. In particular, it is possible to provide this second zone in the upper to warm a part of the foot and / or leg that is not directly inside the shoe, especially the ankle or calf of a person using the overshoe. Advantageously, the heating capacity in the first zone is greater than the heating capacity in the second zone.This makes it advantageously possible to quickly heat the shoe inside the overshoe, while the part of the foot not enclosed by the shoe is not heated too much, in order to avoid burns in particular. This is particularly advantageous if the heat transfer medium has a temperature of substantially at least 50°C, preferably at least 60°C, and / or substantially at most 75°C in at least one part of an area of ​​the overshoe in which a shoe is received, and / or has a temperature of substantially at least 25°C, preferably at least 37°C, and / or substantially at most 45°C in at least one part of an area of ​​the overshoe in which a body part of a user of the overshoe located in the overshoe but not in the shoe is positioned. According to a preferred embodiment, the control device includes a temperature selector that is electrically connected to the energy storage device and / or the heat transfer medium and is configured to influence the duration and / or intensity of the current supplied from the energy storage device to the heat transfer medium. This advantageously allows for setting a desired temperature of the heat transfer medium, starting it up, and / or shutting it down. The control device can be configured, in particular, as a mechanical switch, a capacitive switch, or the like. According to an alternative embodiment of the overshoe according to the invention, at least one pressure sensor and / or at least one temperature sensor and / or at least one humidity sensor is provided, each of which is in operative contact with the heat transfer medium, the energy storage medium, and / or the input medium at least temporarily. The pressure sensor is positioned and configured such that it detects the presence of a shoe and / or a foot inside the overshoe. It is preferably positioned in the sole of the overshoe. The temperature sensor is preferably designed as a thermocouple or as a resistance thermometer and is located at a suitable point on the overshoe, in particular in the sole, the front edge, the front edge cover, the upper, the front section of the upper, and / or the overlap section. Depending on the pressure detected by the pressure sensor, the temperature sensor is adjusted accordingly.Based on the temperature detected by the temperature sensor or the relative or absolute humidity detected by the humidity sensor in the sole or another part of the overshoe, it is advantageously possible to activate, deactivate, and / or keep the heating element, energy storage device, and / or input device running. In particular, it is possible for the energy storage device to only supply energy to the heating element when the pressure sensor detects the presence of a person wearing the overshoe by registering a specific pressure. This advantageously prevents the overshoe from being activated unintentionally.Furthermore, it is particularly possible for the heating element to be activated when the temperature sensor detects a specific initial temperature, and / or for the heating element to be deactivated when the temperature sensor detects a specific second temperature, which is particularly higher than the initial temperature. Finally, it is particularly possible for the heating element to be activated when the humidity sensor detects a specific initial reading, and / or for the heating element to be deactivated when the humidity sensor detects a specific second reading. This advantageously prevents unwanted activation, overheating of the heating element, or an undesirably high temperature for a shoe, foot, or leg section inside the overshoe. Advantageously, the overshoe according to the invention can be provided with a display means configured to indicate at least one physical state of the energy storage device, the heating element, and / or the temperature control device. The display means can be designed, in particular, as an LED, OLED, or display. It can be located at any suitable point on the overshoe, especially on an exterior surface of the front edge, the front edge cover, the shaft, the front shaft section, or the overlap section. This allows, advantageously, the current energy content of the energy storage device, the operating state of the heating element, the temperature of the heating element, or the temperature inside the overshoe to be displayed transparently and easily. In a particularly preferred embodiment, the display means is integrated into the operating device. The operation of the control element is advantageously facilitated if it is located on an outer surface of the first shaft section or the second shaft section. Alternatively or cumulatively, a control element may be positioned on the leading edge, the leading edge cover, the shaft, the front shaft section, or the overlap section, particularly on their respective outer surfaces. According to a further preferred embodiment of the overshoe according to the invention, at least one communication means is provided which is operatively connected, at least temporarily, to the heat transfer medium, the energy storage medium, the operating medium, the pressure sensor, the temperature sensor, the humidity sensor, the electrical interface, and / or the display medium, and is configured to receive signals from at least one transmitter and / or to send signals to a receiver. This advantageously makes it possible, in particular, to transmit operating states of the aforementioned elements to devices located remote from the overshoe and equipped with corresponding receivers. Alternatively or cumulatively, this makes it possible to receive signals from devices located remote from the overshoe and equipped with corresponding transmitters in order to change the operating states of the aforementioned elements.If such a device is a smartphone, tablet computer, computer, server, or similar electronic device, the operating states of the aforementioned elements can be displayed and / or manipulated via the displays or input devices available on the smartphone, etc. The signals can advantageously be transmitted via Bluetooth® or a wireless local area network (WLAN). This advantageously enables remote control of the overshoe and / or remote display of overshoe-related data. According to a further preferred embodiment of the overshoe according to the invention, an insole is provided positioned on the insole. A suitable insole height allows for the compensation of height differences between various shoes within the overshoe, so that even thinner or delicate shoes can be accommodated and securely held in the overshoe. It should be noted that the overshoe can advantageously have various functional material layers. For example, the outer surfaces of the overshoe, with the exception of the previously disclosed sole, can be made of a water-repellent upper material. Adjoining this, looking towards the interior of the overshoe, is a heat-insulating lining fabric, followed by a thin, water-repellent and breathable membrane. The insulating layer is then applied. Furthermore, it can be advantageously provided that at least two eyelets are located on the sole and at least one eyelet on the toe edge cover, through which a drawstring is guided. The drawstring is optionally designed to be released or tightened at both ends of a rotary closure located on the overshoe. The drawstring, which may in particular be designed as a cord, is guided by means of the eyelets located on the left and right outer sides of the sole and the toe edge cover in such a way that the overshoe is tightened in this area, i.e., above and, if applicable, laterally to a shoe located inside the overshoe, by turning the rotary closure in a first direction and released again by turning it in the opposite direction, or alternatively by a different type of release mechanism. Further features and advantages of the invention are illustrated in the accompanying, non-limiting embodiment of the present invention with reference to the accompanying, not-to-scale drawing.

Figure 1A shows a first side of a closed overshoe 1 according to the invention. According to the embodiment shown here, this is the right side or outer side of a right overshoe 1, the heel area 5 of which is on the left in Figure 1A and the toe area 10 of which is on the right in Figure 1A. The overshoe 1 has a waterproof sole 15 that extends to a front edge 20 of the overshoe 1 and has a profile on its underside (not shown here). A front edge cover 25 extends from the front edge 20 over an upper area spaced apart from the sole 15 up to a shaft 30. The upper 30 itself has a first upper section 35, which, according to the previously described convention, is on the right, and a second upper section 40, which, according to the previously described convention, is on the left. The first upper section 35 and the second upper section 40 each extend from an upper shoe edge 45 to a lower shoe edge 50 adjacent to the sole 15. The first upper section 35 and the second upper section 40 are separated from each other along their entire length in the heel area 5 by a gap 55 extending from the upper shoe edge 45 to the lower shoe edge 50, as will be further illustrated by referring to Fig. 5A below. The upper 30 also has a front section 60, which is located on a region of the upper 30 opposite the gap 55.Finally, the overshoe has an overlap section 65, which, according to the embodiment shown here, is located on the second shaft section 40, i.e., attached to it, and extends from the upper edge of the shoe 45 to the lower edge of the shoe 55. The overlap section 65 is flexible and comprises a first overlap section 70, a second overlap section 75, and a common tongue section 80. The first overlap section 70 extends from the upper edge of the shoe 45 to a first end region 85 located away from the sole 15, as symbolized by line I and line II. The distance between the outer edge 90 of the first overlap section 70, which can also be referred to as the upper edge, and an edge 95 of the first shaft section 35 opposite the front edge 60, which can also be referred to as the lower edge, increases up to the first end region 85.The second overlap section 75 extends from the first end region 85 to a second end region 100 adjacent to the sole 15, as symbolized by arrows I and III. The distance between the outer edge 105 of the second overlap section 75, which can also be referred to as the middle edge in relation to the upper and lower edges, decreases from the edge 95 of the first shaft section 35 opposite the front edge 60 to the second end region 100. The first overlap section 70 and the second overlap section 75 merge into the common tongue section 80. In the upper region of the first shaft section 35 shown in Fig. 1A, there is an operating device 110, the function and construction of which will be described later. The operating device 110 is not covered by the overlap section 65, whether the overshoe 1 is open or closed, and is therefore always freely accessible to a user of the overshoe 1 (not shown here). Figure 1B shows the opposite side of the overshoe 1 to that shown in Figure 1A. In other words, Figure 1B depicts the inside of the overshoe 1 shown in Figure 1A. As can be seen, the tongue section 80 extends over the front 60 to essentially the middle of the second shaft section 40. Thus, the overlapping section 65 partially covers the front shaft section 60 when the overshoe 1 is closed. A gripping and opening device 120, designed as a loop, is attached to the end of the tongue section 80. A finger (not shown here) can engage this device to quickly detach the tongue section 80, together with the first end section 85 and the second end section 100, from the shaft 30, thereby allowing the overshoe 1 to be opened quickly and wide. As can be seen from Fig. 1A and Fig. 1B, the overshoe 1 can thus be closed or opened by a means that is easy to manufacture and operate: To close the overshoe 1, it is only necessary to lead the overlap section 65, starting from the second shaft section 40, over the gap 55 and the first shaft section 35 back to the point on the second shaft section 40 and to secure it to the shaft 30 by means of a fastening means 115 which will be described in more detail later. On the outside of the overshoe 1 shown in Fig. 1B is a pocket-shaped receiving element 125 in which a symbolically represented electrical energy storage device 130 is removablely housed. According to the present embodiment, the energy storage device 130, designed as a lithium-polymer battery, is electrically connected to the operating element 110 by means of electrical conductors (not shown). Figure 2 shows a cross-sectional view of the overshoe 1 shown in Figure 1A. As can be seen, the interior 135 of the overshoe 1 contains a shoe 140 designed as a football boot, as is known per se. The studs 145 of the shoe 140, of which only some are labeled in Figure 2 for clarity, rest on the inner side 150 of the sole 15 of the overshoe 1. It is understood, however, that the studs 125 can also be received in recesses in the sole 15, if such recesses are present (not shown). The overshoe 1 of the embodiment shown here has several functional material layers: The outer surfaces of the toe edge cover 25 and the shaft 30 of the overshoe are made of a water-repellent upper material. Adjoining this, looking towards the interior 135 of the overshoe 1, is a heat-insulating lining fabric 160, followed by a thin, water-repellent, and breathable membrane fabric 165. Adjoining this is a heating element 170, which, according to the embodiment shown here, is formed with a number of heating wires (not shown) arranged as mats. These are located on a flexible textile surface structure (not shown here). The heat transfer medium 170 has a first zone 175 that extends along the length of the overshoe 1 within the interior space 135 from the front edge 20 to the heel area 5, excluding the sole 15 according to the embodiment shown here. Viewed vertically along the overshoe 1, the first zone 175 extends from the lower edge of the shoe 50 to an area where the shoe 140 contained within the overshoe 1 essentially ends, as symbolized by line IV. A portion of the foot located within the shoe 140 (not shown here) would thus be separated from the first zone 175 of the heat transfer medium 170 by the shoe 140. Above and adjacent to the first zone 175 is a second zone 180 of the heat transfer medium 170, which in this section also extends along the entire length of the interior space 130 of the overshoe 1.Viewed in the upward direction of the overshoe 1, the second zone 180 extends into the shaft 30 and to an area where the ankle joint of a person using the overshoe 1 (not shown) is essentially located, as symbolized by line V. It is understood, however, that the second zone 180 can also extend further into the shaft 30 towards the upper edge of the shoe 45. The first zone 175 is electrically connected to the energy storage device 130 (symbolically represented) by means of a cable-like functional connection VI. The second zone 180 is electrically connected to the energy storage device 130 by means of a cable-like functional connection VII (symbolically represented). Thus, the heat transfer medium 160 is connected to the energy storage device 130, which in turn is electrically connected to the control device 110 by means of a cable-like functional connection VIII (symbolically represented). The cables provided for the functional connections VII, VIII, and IX can be sewn into the lining fabric 160 of the overshoe 1. By appropriately operating the control device 110, the heat transfer medium 170 is supplied with electrical energy output by the energy storage device 130. The two zones 175 and 180 can be supplied with electrical energy differently.The first zone 175 can be heated to a temperature of 60°C and the second zone 180 to a temperature of 37°C. This prevents, on the one hand, the rapid heating of the interior of the shoe 140 located in the first zone 175, and on the other hand, an excessively high, particularly stressful or even harmful, temperature of the body part of a person wearing the overshoe 1 (not shown here) located in the second zone 180. This body part could, for example, be an ankle. Alternatively or cumulatively, the first zone 175 and the second zone 180 of the heating element 170 can be made of different materials and / or have different heating wire configurations to achieve the desired temperature conditions. The relationships illustrated with reference to Fig. 2 can also be seen in Fig. 3. Fig. 3 corresponds to Fig. 2, except that the shoe 140 is not shown in order to make the first zone 175 and the second zone 180 more visible. As can also be seen more easily in Fig. 3, line IV is not a straight line in the embodiment shown here. Rather, it follows the contour of the upper edge of the shoe 1 inside the overshoe 1. Line V is also not straight in the embodiment shown here, but is essentially concave. Figure 4 shows an alternative embodiment of an overshoe 1 compared to the embodiment shown in Figure 3. This alternative embodiment differs in that an insole 185 is placed on the inner side 150 of the sole 15 within the interior 135 of the overshoe 1. The insole 185 is positively engaged within the interior 135 and can be removed if desired. The insole 185 allows even smaller shoes than the football boot shown in Figure 2 to be securely and non-slip-fitted within the interior 135. Otherwise, the overshoe 1 according to Figure 4 corresponds to the embodiment of an overshoe 1 shown with reference to Figures 2 and 3, so reference is made to their illustrations and descriptions to avoid repetition. In Fig. 5A, the overshoe 1, illustrated with reference to Fig. 1A, is now shown in an open state in a simplified perspective rear view, the illustration of the input means 110 being omitted for the sake of clarity. As can be seen, the first shaft section 35 and the second shaft section 40 are spaced apart from each other such that the gap 55 is wide open. According to the embodiment presented here, the stiffness of the first shaft section 35 is greater than that of the second shaft section 40. This results in a large opening 190 for a shoe (not shown here) to enter or exit the overshoe 1. A first hook-and-loop fastener element 195 is located on the second overlapping section 75, which, when the overshoe 1 is closed, is placed onto a corresponding second hook-and-loop fastener element 200 located on the outside of the overshoe 1. The design of the fastening element 115 according to the embodiment chosen here is also shown in Fig. 5A. Specifically, the fastening element 115 is formed from two hook-and-loop fastener elements 195 and 200, as further illustrated in Fig. 5B, which shows a simplified side view of the overshoe 1 shown in Fig. 5A in a partially closed state. The hook-and-loop fastener element 195 is located on the first tongue section 80, the first end section 85, and the second end section 100. The corresponding hook-and-loop fastener element 200 is located on the first shaft section 35 and the second shaft section 40, respectively. Figure 6 shows a side view of an alternative overshoe 1 according to the representation in Figure 1B. The overshoe 1 shown here has, in principle, all the features of the overshoe 1 shown in relation to Figure 1. In addition, however, it is provided that two eyelets 205 are located on the sole 15 and further eyelets 210 are located on the front edge cover 25, through which a drawstring 215 is guided. The drawstring 215 is designed with its two ends to be either releasable or tensioned on a rotary fastener 220 located on the overshoe 1. The drawstring 215 is guided by means of the eyelets 205, 210 located on the left and right outer sides of the sole 15 and the front edge cover 25 in such a way that the overshoe 1 is secured in this area, i.e., above and, if necessary,The pull tab 220 is tightened laterally by turning the dial 220 in a first direction and released again by turning it in the opposite direction, or alternatively by a different release mechanism not shown here, on the side of a shoe located inside the overshoe 1 (not shown here). It is understood that the overshoe 1 has further corresponding eyelets 205 on its side beyond the plane of the paper, i.e., on the inside of the overshoe 1, which are not visible due to the perspective chosen here. The pull tab 215 is also guided through these eyelets. It should also be noted that, according to an alternative embodiment not shown here, the eyelets 205, the eyelets 210, the pull tab 215, and the dial 220 can be located wholly or partially inside the overshoe 1. Figure 7 shows an enlarged view of the control device 110, which is illustrated with reference to Figures 1B, 5B, and 6. The control device 110 comprises a first, central area 225 in which an on / off switch 230 is positioned. Adjoining the first area 225 is a second, essentially L-shaped area 235, in which a first input device 240 and a first display device 245 are positioned. According to the embodiment shown here, the first display device 245 consists of three LEDs. Opposite the second area 235 and adjoining the first area 225 is a third area 250, which is essentially in the shape of an inverted L. A second input device 255 and a second display device 260 are positioned in the third area 250. The on / off switch can be used to activate or deactivate all electrical components in the overshoe 1. The first input device 240 can decrease the temperature of the heat transfer medium 170. The second input device 255 can increase the temperature of the heat transfer medium 170. The first indicator device 245 displays various temperature levels, thus providing an indication of the temperature of the heat transfer medium 170. For example, a first LED can be illuminated when the temperature measured at a point in the overshoe 1 reaches 45°C. A second LED can be illuminated when the temperature at the same point reaches 55°C. Finally, a third LED can be illuminated when the temperature at the same point reaches 65°C. The second indicator device 260 displays the actual electrical capacity present in the energy storage device 130.The indicator can, for example, display a red light in a first capacity range representing between 1% and 20% of the maximum nominal capacity of the energy storage unit 130, a yellow light in a second capacity range representing between 21% and 80% of the maximum nominal capacity of the energy storage unit 130, and a green light in a third capacity range representing between 81% and 100% of the maximum nominal capacity of the energy storage unit 130. It is understood that the on / off switch 230, the input devices 240, 255, and the display devices 245, 260 are operatively connected to the energy storage unit 130 and, if necessary, to the heat transfer device 170. It should be noted that the overshoes 1 described above, in addition to the features and functions explained above, may cumulatively or alternatively, even if not shown in the figures, have a temperature control device that is electrically connected to the energy storage device 130 and / or the heat transfer medium 170 and is configured to influence the duration and / or the intensity of the current supplied from the energy storage device 130 to the heat transfer medium 170. Cumulatively or alternatively, it is possible to provide a pressure sensor and / or at least one temperature sensor and / or at least one humidity sensor and / or an electrical interface, for example a USB-C interface, each of which is at least temporarily connected to the heat transfer medium 170, the energy storage device 130 and / or at least one of the two input devices 240, 255. Figure 8 shows an overshoe 1 as depicted in Figure 1A, which additionally includes a communication means 265. The communication means 265 has a transmitter and receiver (not shown here) which is operatively connected to a corresponding transmitter and receiver (also not shown) of a communication means 270 (shown here symbolically as a smartphone), as symbolized by the double arrows IX. Inside the overshoe 1, the communication means 265 is operatively connected to the control means 110 and at least one other electrical or electronic element located therein, as symbolized by the double arrows X and XI, respectively.This means that the communication device 265 is at least temporarily in operative communication with, for example, the heat transfer medium 170, the energy storage device 130, the control device 110, the pressure sensor, the temperature sensor, the humidity sensor, the electrical interface and / or the display devices 245, 260, so that signals can be transmitted from the overshoe 1 to the communication device 270 and back. The signals transmitted to the communication device 270 represent data that is determined in the overshoe 1 and, for example, represent status information (actual information) of the energy storage device 130 (e.g., current capacity or fill level or temperature) or of the heat transfer medium 170 (e.g., current temperature of the heat transfer medium 170, current temperature of the first zone 175, current temperature of the second zone 180).The signals received by the receiver of the communication device 265 located in the overshoe 1, on the other hand, represent, for example, information that serves as input variables for achieving a desired operating state of the overshoe 1 (target information). This includes, for example, a target temperature of the heat transfer medium 170, a target temperature of the first zone 175, a target temperature of the second zone 180, or a target humidity level within the overshoe 1. In Fig. 8, the overshoe 1 was addressed according to the representation in Fig. 1A. However, it is understood that an overshoe 1 according to the representation in Fig. 6 can also be equipped with a communication means 265, even if this is not shown further in the figures.
