[0001] Overshoe for one shoe
[0002] The present invention relates to an overshoe for a shoe according to claim 1.
[0003] In principle, overshoes for shoes are known. For example, US 10,299,532 B2 discloses an overshoe for a shoe, which 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 shoe edge to a lower shoe edge adjacent to the sole and separated from one another by a gap extending from the upper shoe edge to the lower shoe edge in a heel region of the overshoe. Furthermore, the known overshoe has a shaft front section, which is located in a region of the shaft opposite the gap, and a fastening means which is designed to releasably fasten the overlapping section to the shaft.To warm this overshoe, a heating element designed as a heat pad is attached to an insole, which in turn is inserted into the overshoe. This overshoe, known from US Pat. No. 10,299,532 B2, has the disadvantage that adjustable and controlled heat transfer 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 from the overshoe. This is disadvantageously impractical and time-consuming.
[0004] An overshoe with an electric heating element is known from US 2006 / 0248747 A1. The overshoe consists of a flexible sheet material equipped with heating wires and is pulled over the front edges and the front edge cover adjoining the front edge 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 via a strap spanning the sole of the shoe and a fastening device provided in the heel area of the shoe. Due to this construction, the overshoe known from US 2006 / 0248747 A1 is disadvantageously unstable.
[0005] Finally, from DE 10 2009 033 142 A1, an overshoe is known, comprising: a sole, a front edge, a front edge cover adjoining the front edge, and a shaft adjoining the front edge cover, having 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 one another by a gap extending from the upper shoe edge to the lower shoe edge in a heel region of the overshoe, a shaft front section located in 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 and selectively closing the gap or opening it to form an opening, and at least one fastening means attached to the shaft, which is designed toto releasably attach the overlap section to the shaft.,
[0006] The transfer of heat from the overshoe known from DE 102009 033 142 A1 to a shoe located inside it is not provided. Therefore, controlled heating of the shoe is disadvantageously not possible. Furthermore, due to its construction, rapid insertion of the shoe into the overshoe and rapid removal of the shoe from the overshoe are not really possible. The object of the present invention is to provide an overshoe that can be easily and quickly put on and taken off by a wearer, and in which controlled heat transfer to the shoe is efficient.
[0007] The object is achieved according to the invention with the features of claim 1. Further embodiments of the invention emerge from the dependent claims.
[0008] 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, comprising 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 one another by a gap extending from the upper shoe edge to the lower shoe edge in a heel region of the overshoe, a shaft front section located in 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, and selectively closing the gap or opening it to form an opening,and at least one fastening means attached to the shaft, which is configured to releasably attach the overlap portion to the shaft.
[0009] The overshoe according to the invention is characterized in that the overlap section has a first overlap section which extends from the upper edge of the shoe to a first end region remote from the sole, wherein the distance of the outer edge of the first overlap section increases from an edge of the first shaft section or of the second shaft section opposite the front edge to the first end region, the overlap section has a second overlap section which 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 decreases from the edge of the first shaft section or of the second shaft section opposite the front edge to the second end region, the overlap section is configured,to at least partially cover the front section of the shaft when the overshoe is closed, at least one heating means 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 which supplies the at least one heating means with electrical energy at least temporarily, and at least one operating means is operatively connected to the at least one heating means and / or the at least one storage device.
[0010] In other words, the overshoe according to the invention is designed to accommodate a shoe worn by a person. This shoe can be designed in any suitable manner. Thus, it is advantageously a football boot.
[0011] The overshoe has a sole. This sole is designed in any suitable way. It can advantageously have a first, outer side with which the overshoe rests on a support surface, for example earth, grass, concrete or the like, when in use, and which can be regarded as an outsole of the overshoe. This outer side of the sole preferably has a profile and / or studs to make the overshoe particularly slip-resistant relative to its support surface. In addition, the sole has a second, inner side which faces the interior of the overshoe and can be regarded as the insole of the overshoe. Thus, the sole of a shoe located inside the overshoe rests against the inner side of the sole of the overshoe. The inner side of the sole of the overshoe is preferably designed to complement the sole of the shoe located inside the overshoe.In particular, recesses can advantageously be provided on the inner side of the sole of the overshoe, into which projections of the sole of the shoe located in the interior of the overshoe, in particular profile projections and / or studs, are received. Alternatively, the inner side of the overshoe can preferably be designed to be substantially smooth in order to support the desired rapid 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 caoutchouc. The sole is preferably designed to be waterproof at least on its outer side.
[0012] The overshoe according to the invention further comprises a front edge that defines its front region outwards and inwards. The inner side of the front edge, i.e., the region of the overshoe opposite the toe region of a shoe accommodated in the overshoe, preferably has a geometric shape that is substantially complementary to the front region of the accommodated shoe. The inner side of the front edge of the overshoe can optionally rest against the outer surface of the shoe accommodated in the overshoe.
[0013] Adjoining the front edge of the overshoe according to the invention, viewed in the direction of a heel area of the overshoe, is a front edge cover. This extends transversely across the entire width of the overshoe. Thus, the front edge cover is located essentially in an area where a midfoot located in a shoe, which in turn is accommodated in the overshoe, is positioned.
[0014] The front edge cover of the overshoe according to the invention is adjoined by a shaft, viewed in the direction of a heel region of the overshoe. The shaft has a first shaft section and a second shaft section, each extending from an upper shoe edge of the overshoe to a lower shoe edge adjacent to the sole and separated from one another by a gap extending essentially in a heel region of the overshoe from the upper shoe edge to the lower shoe edge. Any one or each of the shaft sections can be made of any suitable material. In particular, it is possible to design one or each shaft section to be inherently rigid or flexible.
[0015] In an area of the shaft opposite the gap there is a shaft front section. In other words, the shaft front section faces the front edge of the overshoe. If the first shaft section and the second shaft section are provided as separate elements on the overshoe, they are connected to one another detachably or non-detachably via a connecting means on the shaft front section. The detachable connection is made in particular by a hook-and-loop connection or a zipper. The non-detachable connection is made in particular by a material-locking and / or positive-locking connection of the two shaft sections, in particular by injection molding, an adhesive connection or a welded connection. Alternatively, it can be provided that the first shaft section and the second shaft section are formed as a single piece in the area of the shaft front section.
[0016] The overshoe according to the invention additionally has an overlap section which is located on one of the two shaft sections, extends from the upper edge of the shoe to the lower edge of the shoe and optionally closes the gap or opens it up to form an opening. The overlap section can be made of any suitable material. In particular, it is possible to make the overlap section inherently rigid or flexible. The length of that part of the overlap section which is connected to the shaft section or which is formed integrally with it can be of any suitable size. It is thus possible to form this connecting region between the overlap section and the shaft section over the entire length of the gap or only over a portion of the length of the gap. In principle, the overlap section can be located on any suitable area of the shaft, in particular on the left side or the right side of the shaft, ora corresponding shaft section may be provided. Therefore, if the overshoe is designed to accommodate a right-hand shoe, the overlap section is advantageously positioned on the left-hand shaft section, as viewed from the heel region towards the front edge. In this case, when the overshoe which can be designated as a right-hand overshoe is closed, a part of the overlap section remote from the left-hand shaft section is fastened to the right-hand shaft section. Advantageously, it can be provided that the overlap section is guided over the right-hand shaft section further onto the left-hand shaft section. If, on the other hand, the overshoe is designed to accommodate a left-hand shoe, the overlap section is advantageously positioned on the right-hand shaft section, as viewed from the heel region towards the front edge.In this case, when the overshoe designated as the left overshoe is closed, a part of the overlap section remote from the right shaft section is attached to the left shaft section. Advantageously, the overlap section can be extended over the left shaft section to the right shaft section. Overall, this advantageously enables a simple and thus quick closing and opening process for the overshoe according to the invention.
[0017] The overshoe according to the invention has at least one fastening means attached to the shaft, which is designed to releasably fasten the overlapping section to the shaft. The fastening means makes it possible to releasably fasten the overlapping section to the shaft. The releasable connection is achieved, in particular, by means of a hook-and-loop connection, a hook-and-eye connection, or a zipper. It is understood that the fastening means interacts with a corresponding element located on the overlapping section. In particular, the overlapping section and the shaft can have elements of a hook-and-loop fastener that can be brought into contact with one another or detachable from one another.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 engaging positively in the opening, with eyelets corresponding to the hooks or with locking elements engaging in the eyelets.
[0018] The overshoe according to the invention is characterized by a special design of the overlapping section:
[0019] The overlap section has a first overlap section which extends from the upper edge of the shoe to a first end region remote from the sole, wherein the distance of the outer edge of the first overlap section increases from an edge of the first shaft section or the second shaft section opposite the front edge to the first end region.
[0020] The overlapping section has a second overlapping section which 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 overlapping section decreases from the edge of the first shaft section or of the second shaft section opposite the front edge to the second end region.
[0021] The overlapping section is designed to at least partially cover the front section of the shaft when the overshoe is closed.
[0022] This design advantageously creates an opening in the overshoe that is sufficiently large and accessible for inserting or removing a shoe from the overshoe. Furthermore, this advantageously enables easy, thus quick, and reliable opening and closing of the overshoe.
[0023] It should be noted that each shaft section can have the same stiffness. Alternatively, the shaft section where the overlap section is located can have a higher stiffness than the other shaft section. This advantageously allows the opening characteristics of the overshoe to be determined, in particular the shape and size of the opening provided for inserting or removing the shoe.
[0024] 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 accommodated therein, which occurs precisely, thus corresponding to a desired position.
[0025] The heating medium itself comprises a flexible sheet-like structure, in particular in the form of a fabric or a foam, or an inflexible sheet-like structure, in particular in the form of an inherently rigid wall, in each of which at least one heating wire, particularly preferably at least one heating mat, is located. According to a preferred embodiment of the heating medium, the heating wire is fixed in a meandering manner to the sheet-like structure with a cover layer, in particular by an embroidery thread. Alternatively or cumulatively, the heating wire or the heating mat can be inserted or foamed into a flexible carrier foam of the sheet-like structure. Alternatively or cumulatively, the heating medium comprises a number of heating conductors connected electrically in parallel, which are attached to the sheet-like structure. The heating conductors consist of carbon fibers, a metal, or are designed as PTC heating elements.
[0026] It should be noted that the sheet-like structure can preferably be designed as a membrane having, at least on a portion of its surface adjacent to a shoe accommodated in the overshoe, spacing means and pore-like openings 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 means must be supplied with electrical energy. Therefore, according to the invention, at least one energy storage means is provided, which is designed as a battery, an accumulator, or a capacitor. The energy storage means is operatively electrically connected to the heating means. It can be designed to be removable or non-removable from the overshoe. Particularly advantageously, the accumulator is designed as a lithium polymer accumulator, which, due to its arbitrary formability, can be easily adapted to the geometry of the overshoe that accommodates it.
[0027] Furthermore, according to the invention, at least one operating means is provided which is operatively connected to the at least one heating means and / or the at least one energy storage means in order to switch the heating means on, off and / or otherwise bring about a change in the energy emitted by the heating means.
[0028] By means of the previously disclosed heating means, energy storage means and operating means, the overshoe according to the invention can advantageously be heated quickly, reliably and conveniently.
[0029] Overall, this creates an overshoe that can be put on and taken off quickly and easily by the wearer, and which efficiently releases controlled heat to the shoe.
[0030] According to a preferred embodiment of the overshoe according to the invention, it is provided that the first overlapping section and / or the second overlapping section, when the overshoe is closed, extends beyond the gap and the front shaft section at least partially onto that shaft section which does not correspond to the shaft section on which the overlapping section is positioned. Therefore, when the first overlapping section is positioned, and therefore arranged or fastened, on the first shaft section, it can be moved beyond the gap onto the second shaft section and fastened thereto. According to a particularly preferred embodiment, it can be provided that the first overlapping section is guided further beyond the second shaft section onto the first shaft section. However, when the first overlapping section is positioned, and therefore arranged or fastened, on the second shaft sectionfastened, it can be moved across the gap onto the first shaft section and fastened thereto. If the second overlapping section is positioned, and therefore arranged or fastened, on the first shaft section, it can be moved across the gap onto the second shaft section and fastened thereto. If, on the other hand, the second overlapping section is positioned, and therefore arranged or fastened, on the second shaft section, it can be moved across the gap onto the first shaft section and fastened thereto. According to a particularly preferred embodiment, it can be provided that the second overlapping section is guided beyond the first shaft section and further onto the first shaft section. Overall, this advantageously achieves a quick and effective closure of the overshoe in the region of the shaft. This can be opened again just as reliably and quickly.
[0031] According to a further preferred embodiment of the overshoe according to the invention, the first overlapping section and the second overlapping section have a common tongue section. This is preferably located at the respective ends of the first overlapping section and the second overlapping section remote from the shaft. The tongue section is preferably formed as a common end of the first overlapping section and the second overlapping section 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 closing and opening of the overshoe.
[0032] 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 replaceable or non-replaceable. It is conceivable to accommodate the energy storage device in the area of the sole of the overshoe, either replaceable or non-replaceable. However, according to a preferred embodiment of the overshoe according to the invention, a receiving means accessible from the outer surface of the overshoe and accommodating the energy storage device is provided. This can be designed, in particular, as a closable or non-closable pocket. This allows for easy replacement of the energy storage device.
[0033] It should be noted that an electrical interface can advantageously be provided on the overshoe, which is operatively electrically connected to the electrical energy 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 output electrical energy and / or electrical signals from a source remote from the overshoe, in particular a battery charger, to the overshoe via the interface. It should be noted that the electrical energy can also be supplied alternatively or cumulatively by induction.
[0034] In principle, the at least one heating means can be located at any suitable location on the overshoe. However, according to a preferred embodiment, the at least one heating means extends at least partially from the front edge cover toward the heel area. Alternatively or additionally, the at least one heating means is located at least partially in the first shaft section and / or the second shaft section. This advantageously makes it possible to release heat in specific areas or sections of the overshoe.
[0035] This is all the more true if the at least one heating means has at least two zones with different heating outputs. For example, it is advantageously possible to provide a first zone located in the area of the overshoe adjacent to a shoe accommodated therein. A second zone can be connected to the first zone, either directly adjacent to it or at a distance from it. For example, it is particularly possible to provide this in the shaft in order to warm a part of a foot and / or a leg that is not directly located in the shoe, i.e. in particular the ankle or a calf of a person wearing the overshoe. Advantageously, the heating output in the first zone is greater than the heating output in the second zone.This advantageously makes it possible to heat the shoe located in the overshoe quickly, while the part of the foot located in the overshoe that is not covered by the shoe is not heated too much, in particular to avoid burns.
[0036] This advantageously applies in particular when the heating means has a temperature of substantially at least 50°C, preferably of at least 60°C, and / or substantially at most 75°C in at least part of a region of the overshoe in which a shoe is accommodated, and / or has a temperature of substantially at least 25°C, preferably of at least 37°C, and / or at most 45°C in at least part of a region of the overshoe in which a body part of a user of the overshoe, which body part is located in the overshoe but not in the shoe, is positioned.
[0037] According to a preferred embodiment, the operating means comprises a temperature selection means that is electrically connected to the energy storage device and / or the heating medium and is configured to influence the duration and / or intensity of a current output from the energy storage device to the heating medium. This advantageously makes it possible to set a desired temperature for the heating medium, to activate the heating medium, and / or to deactivate the heating medium. The operating means can be designed, in particular, as a mechanical switch, a capacitive switch, or the like.
[0038] 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 at least temporarily operatively connected to the heating means, the energy storage means and / or the input means. The pressure sensor is positioned and configured such that it detects the presence of a shoe located in the overshoe and / or the presence of a foot located in the overshoe. It is preferably positioned in the sole of the overshoe. The temperature sensor is designed in particular as a thermocouple or as a resistance thermometer and is located at a suitable location on the overshoe, in particular in the sole, the front edge, the front edge cover, the shaft, the front section of the shaft and / or the overlap section. Depending on the pressure or humidity detected by the pressure sensor, the temperature sensor is switched on.Depending on the temperature detected by the temperature sensor or the relative or absolute humidity in the sole or another part of the overshoe detected by the humidity sensor, it is advantageously possible to activate, deactivate, and / or maintain the operation of the heating means, the energy storage means, and / or the input means. In particular, it is possible for the energy storage means to only supply energy to the heating means when the pressure sensor detects the presence of a person using the overshoe by detecting a specific pressure. This advantageously prevents the overshoe from being activated inadvertently.Furthermore, it is particularly possible for the heating means to be activated when the temperature sensor detects a specific first temperature and / or for the heating means to be deactivated when the temperature sensor detects a specific second temperature which is in particular higher than the first temperature. Finally, it is particularly possible for the heating means to be activated when the humidity sensor detects a specific first measured value and / or for the heating means to be deactivated when the humidity sensor detects a specific second measured value. This advantageously prevents undesired activation or overheating of the heating means or an undesirably high temperature for a shoe or foot or leg section located in the overshoe.
[0039] Advantageously, the overshoe according to the invention can be provided with a display means configured to display at least one physical state of the energy storage device, the heating means, and / or the temperature selection means. The display means can be designed, in particular, as an LED, OLED, or as a display. It can be located at any suitable location on the overshoe, in particular in an outer region of the front edge, the front edge cover, the shaft, the front section of the shaft, or the overlap section. This advantageously allows, in particular, the current energy content of the energy storage device, the operating state of the heating means, the temperature of the heating means, or the temperature inside the overshoe to be displayed transparently and easily. Particularly preferably, the display means is designed on the operating means.
[0040] The handling of the operating means is advantageously facilitated if it is located on an outer side of the first shaft section or the second shaft section. Alternatively or cumulatively, an operating means can be positioned on the leading edge, the leading edge cover, the shaft, the shaft front section, or the overlap section, in particular on their respective outer sides.
[0041] According to a further preferred embodiment of the overshoe according to the invention, at least one communication means is provided, which is at least temporarily operatively connected to the heating means, the energy storage means, the operating means, the pressure sensor, the temperature sensor, the humidity sensor, the electrical interface and / or the display means 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 send operating states of the aforementioned elements to devices remote from the overshoe and provided with corresponding receivers. Alternatively or cumulatively, this makes it possible to receive signals from devices remote from the overshoe and provided with corresponding transmitters in order to change the operating states of the aforementioned elements.Thus, in the event that such a device is a smartphone, a tablet computer, a computer, a server, or similar electronic device, the operating states of the aforementioned elements can be displayed and / or manipulated via the displays or input means present 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-relevant data. According to an additional preferred embodiment of the overshoe according to the invention, an insole positioned on the inner sole is provided. By selecting a suitable height for the insole, height differences between different shoes can be compensated for in the overshoe, so that even thinner or finer shoes can be accommodated and held securely in the overshoe.
[0042] It should be noted that the overshoe can advantageously comprise 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 outer material. Adjacent to this, viewed toward the interior of the overshoe, is a heat-insulating lining fabric, followed by a thin, water-repellent and breathable membrane fabric. The thermal agent is then connected to this.
[0043] Furthermore, it can advantageously be provided that there are at least two eyelets on the sole and at least one eyelet on the front edge cover, through which a pulling means is guided, which is designed with its two ends to be optionally loosened or tightened on a twist lock located on the overshoe. The pulling means, which can in particular be designed as a cord, is guided by means of the eyelets located on the left and right outer side of the sole and the front edge cover in such a way that the overshoe in this area, thus above and possibly to the side of a shoe located in the overshoe, is tightened by turning the twist lock in a first direction and loosened by turning it in the opposite direction, alternatively by a different type of
[0044] release mechanism, is released again.
[0045] Further features and advantages of the invention are illustrated in the attached, non-limiting embodiment of the present invention with reference to the attached, not to scale drawing.

[0053] Fig. 7 is an enlarged view of an operating means shown in Figs. 1 B, 5B and 6, and
[0054] Fig. 8 is a symbolic view of an overshoe according to Fig. 1A, which is formed with a communication means and is in operative connection with a communication means shown symbolically and spaced from the overshoe.
[0055] Fig. 1A shows a first side of a closed overshoe 1 according to the invention. According to the exemplary embodiment shown here, this is the right side or outer side of a right-hand overshoe 1, the heel region 5 of which is on the left in Fig. 1A and the toe region 10 of which is on the right in Fig. 1A. The overshoe 1 has a waterproof sole 15 which extends to a front edge 20 of the overshoe 1 and has a profile on its underside (not shown here). Starting from the front edge 20, a front edge cover 25 extends over an upper region spaced from the sole 15 up to a shaft 30. The shaft 30 itself has a first shaft section 35, which is on the right according to the previously described convention, and a second shaft section 40, which is on the left according to the previously described convention.The first shaft section 35 and the second shaft section 40 each extend from an upper shoe edge 45 to a lower shoe edge 50 adjacent to the sole 15. The first shaft section 35 and the second shaft section 40 are separated from one another in the heel region 5 over their entire length by a gap 55 extending from the upper shoe edge 45 to the lower shoe edge 50, as is even more clearly seen when considering the following Fig. 5A. The shaft 30 additionally has a shaft front section 60, which is located in a region of the shaft 30 opposite the gap 55. Finally, the overshoe has an overlap section 65, which, according to the exemplary embodiment shown here, is located on the second shaft section 40, i.e. is fastened to it, and extends from the upper shoe edge 45 to the lower shoe edge 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 shoe edge 45 to a first end region 85 remote from the sole 15, as symbolized by the line I and the line II. The distance of the outer edge 90 of the first overlap section 70, which can also be referred to as the upper edge, increases from an edge 95 of the first shaft section 35 opposite the front edge 60, which edge can also be referred to as the lower edge, 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 the arrows I and III.The distance of the outer edge 105 of the second overlapping section 75, which can also be referred to as the middle edge with reference to the upper edge and lower edge, decreases from the edge 95 of the first shaft section 35 opposite the front edge 60 to the second end region 100. The first overlapping section 70 and the second overlapping section 75 open into the common tongue section 80.
[0056] Located in the upper area of the first shaft section 35 in Fig. 1A is an operating means 110, the function and structure of which will be described below. The operating means 110 is not covered by the overlapping section 65 when the overshoe 1 is either open or closed and is thus always freely accessible to a user of the overshoe 1 (not shown here).
[0057] Fig. 1B now shows the opposite side of the side of the overshoe 1 shown in Fig. 1A. In other words, Fig. 1B shows the inside of the overshoe 1 of Fig. 1A. As can be seen, the tongue section 80 extends over the front side 60 up to substantially the middle of the second shaft section 40. Thus, the overlap section 65 partially covers the shaft front section 60 when the overshoe 1 is closed. At the end region of the tongue section 80, a gripping and opening means 120 designed as a loop is attached, into which a finger (not shown here) can engage in order to quickly detach the tongue section 80 together with the first end region 85 and the second end region 100 from the shaft 30 and to enable a quick and wide opening of the overshoe 1.
[0058] As can be seen from Figures 1A and 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 guide the overlapping section 65, starting from the second shaft section 40, over the gap 55 and the first shaft section 35 back to the second shaft section 40 and to secure it to the shaft 30 by means of a fastening means 115 to be described in more detail.
[0059] On the outside of the overshoe 1 shown in Fig. 1B there is a receiving means 125 designed as a pocket, in which a symbolically represented electrical energy storage device 130 is removably accommodated. The energy storage device 130, designed as a lithium polymer accumulator according to the present embodiment, is in electrical connection with the operating means 110 by means of electrical lines not shown here. Fig. 2 now shows a sectional view of the overshoe 1 shown in Fig. 1A. As can be seen, in the interior 135 of the overshoe 1 there is a shoe 140 designed as a known football shoe. The studs 145 of the shoe 140, of which only a few are provided with reference numerals in Fig. 2 for reasons of 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 are present (not shown).
[0060] The overshoe 1 of the exemplary embodiment shown here has various functional material layers: The outer surfaces of the overshoe, the front edge cover 25 and the shaft 30, are made of a water-repellent outer material. Adjacent to this, viewed toward the interior 135 of the overshoe 1, is a heat-insulating lining fabric 160, followed by a thin, water-repellent and breathable membrane material 165. Adjacent to this is a heating element 170, which, according to the exemplary embodiment presented here, is formed with a number of heating wires (not shown here) in the form of mats. These are located on a flexible textile fabric not designated by any reference numerals.
[0061] The heating means 170 has a first zone 175 that extends over the length of the overshoe 1 in the interior space 135 from the front edge 20 to the heel region 5, wherein the sole 15 is recessed therefrom according to the exemplary embodiment shown here. The first zone 175 extends, viewed in the vertical direction of the overshoe 1, from the lower shoe edge 50 to an area in which the shoe 140 accommodated in the overshoe 1 essentially ends, as symbolized by the line IV. A part of a foot, not shown here, located in the shoe 140 would thus be separated from the first zone 175 of the heating means 170 by the shoe 140. Above the first zone 175 and adjacent to it is a second zone 180 of the heating means 170, which in this section also extends over the entire length of the interior space 130 of the overshoe 1.Viewed in the vertical direction of the overshoe 1, the second zone 180 extends into the upper 30 and up to an area in which the ankle joint of a person using the overshoe 1 (not shown) is essentially located, as symbolized by the line V. However, it is understood that the second zone 180 can also extend further into the upper 30 toward the upper shoe edge 45.
[0062] The first zone 175 is electrically connected to the symbolically represented energy storage device 130 by means of an active connection VI, symbolically represented as a cable. The second zone 180 is electrically connected to the energy storage device 130 by means of an active connection VII, symbolically represented as a cable. Thus, the heating medium 160 is connected to the energy storage device 130, which in turn is electrically connected to the operating device 110 by means of an active connection VIII, symbolically represented as a cable. The cables provided for the active connections VII, VIII, and IX can be sewn into the lining fabric 160 of the overshoe 1. By appropriately operating the operating device 110, the heating 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.Thus, the first zone 175 can be heated to a temperature of 60°C and the second zone 180 to a temperature of 37°C, on the one hand to prevent rapid heating of the interior of the shoe 140 located in the first zone 175, and on the other hand to prevent an excessively high, particularly stressful or even harmful, temperature of that body part of a person using the overshoe 1 (not shown here) that is located in the second zone 180. This body part can be, for example, an ankle joint. Alternatively or cumulatively, it can be provided that the first zone 175 and the second zone 180 of the heating means 170 are made of different materials and / or can have different heating wire designs in order to maintain the desired temperature conditions.
[0063] The relationships illustrated with reference to Fig. 2 can also be seen in Fig. 3. Figure 3 corresponds to Fig. 2, but an illustration of the shoe 140 has been omitted in order to make the first zone 175 and second zone 180 more visible. As can also be more easily seen in Fig. 3, the line IV according to the exemplary embodiment shown here is not a straight line. Rather, it follows the course of the contour of the upper shoe edge of the shoe 1 located in the overshoe 1. The line V according to the exemplary embodiment shown here is also not straight, but is essentially concave.
[0064] Fig. 4 shows an alternative embodiment of an overshoe 1 to the embodiment of the overshoe 1 shown in Fig. 3. This differs in that an insole 185 is placed on the inner side 150 of the sole 15 in the interior 135 of the overshoe 1. The insole 185 is received in the interior 135 in a form-fitting manner and can be removed therefrom if desired. With the insole 185, it is possible to accommodate even smaller shoes than the football boot shown in Fig. 2 in a slip-resistant manner in the interior 135. Otherwise, the overshoe 1 according to Fig. 4 corresponds to the embodiment of an overshoe 1 shown with reference to Figs. 2 and 3, so that to avoid repetition, reference is made to their illustration and description.
[0065] In Fig. 5A, the overshoe 1 illustrated with reference to Fig. 1A is now shown in the open state in a simplified perspective rear view, wherein the input means 110 has been omitted for reasons of clarity. As can be seen, the first shaft section 35 and the second shaft section 40 are spaced from one another such that the gap 55 is wide open. According to the exemplary embodiment presented here, the rigidity 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 the overshoe 1 or to exit it therefrom. On the second overlap section 75 there is a first hook-and-loop fastener element 195 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.
[0066] The design of the fastening means 115 according to the embodiment chosen here is also shown in Fig. 5A. Specifically, the fastening means 115 is formed from two hook-and-loop fastener elements 195, 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 region 85, and the second end region 100. The corresponding hook-and-loop fastener element 200 is located on the first shaft section 35 and the second shaft section 40, respectively.
[0067] Fig. 6 shows a side view of an alternative overshoe 1 according to the representation in Fig. 1B. The overshoe 1 shown here basically has all the features of the overshoe 1 shown in relation to Fig. 1. In addition, however, there is provision for two eyelets 205 to be located on the sole 15 and further eyelets 210 to be located on the front edge cover 25, through which a pulling means 215 is guided. The pulling means 215 is designed with its two ends to be optionally released or tightened on a twist fastener 220 located on the overshoe 1. The pulling means 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 in this area, thus above and if necessaryto the side of a shoe located in the overshoe 1 (not shown here), is tightened by turning the twist lock 220 in a first direction and is released again by turning it in the opposite direction, alternatively by a different release mechanism not shown here. It is understood that the overshoe 1 has further corresponding eyelets 205 on its side beyond the plane of the paper, thus the inside of the overshoe 1, which, however, are not visible due to the perspective chosen here. The pulling means 215 is also guided through these. It should also be noted that according to an alternative embodiment not shown here, the eyelets 205, the eyelets 210, the pulling means 215 and the twist lock 220 can be located wholly or partially within the overshoe 1.
[0068] Fig. 7 shows an enlarged view of the operating means 110 illustrated with reference to Figs. 1B, 5B and 6. The operating means 110 comprises a first, central region 225 in which an on / off switch 230 is positioned. Adjacent to the first region 225 is a second, substantially L-shaped region 235 in which a first input means 240 and a first display means 245 are positioned. According to the exemplary embodiment shown here, the first display means 245 consists of three LEDs. Opposite the second region 235 and adjoining the first region 225 is a third region 250 which is substantially in the shape of an inverted L. A second input means 255 and a second display means 260 are positioned in the third region 250.
[0069] The on / off switch can be used to switch all electrical components in the overshoe 1 on or off. The first input means 240 can be used to reduce the temperature of the heating medium 170. The second input means 255 can be used to increase the temperature of the heating medium 170. The first display means 245 shows various temperature levels, thus indicating the temperature of the heating medium 170. For example, a first LED can be switched on when the temperature measured at a measuring point in the overshoe 1 is 45°C. A second LED can be switched on when the temperature recorded at said measuring point is 55°C. Finally, the third LED can be switched on when the temperature recorded at the measuring point is 65°C. The second display means 260 shows the actual electrical capacity present in the energy storage device 130.For example, the display may emit a red light for a first capacity range representing between 1% and 20% of the maximum rated capacity of the energy storage device 130, a yellow light for a second capacity range representing between 21% and 80% of the maximum rated capacity of the energy storage device 130, and a green light for a third capacity range representing between 81% and 100% of the maximum rated capacity of the energy storage device 130. It is understood that the on / off switch 230, the input means 240, 255, and the display means 245, 260 are operatively connected to the energy storage device 130 and, if necessary, to the heating means 170.
[0070] It should be noted that, in addition to the previously explained features and functions, the previously illustrated overshoes 1 can cumulatively or alternatively, even if not shown in the figures, comprise a temperature selection means that is in electrically operative connection with the energy storage device 130 and / or the heating means 170 and is configured to influence the duration and / or the intensity of a current output from the energy storage device 130 to the heating means 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 operatively connected to the heating means 170, the energy storage device 130 and / or at least one of the two input means 240, 255.
[0071] Fig. 8 shows an overshoe 1 according to the illustration in Fig. 1A, which additionally comprises a communication means 265. The communication means 265 has a transmitting and receiving means (not shown here in detail), which are operatively connected to a corresponding transmitting and receiving means (also not shown) of a communication means 270, symbolically shown here, designed as a smartphone, as symbolized by the double arrows IX. Within the overshoe 1, the communication means 265 is operatively connected to the operating means 110 and at least one further electrical or electronic element located therein, as symbolized by the double arrows X and XI, respectively.Thus, the communication means 265 is at least temporarily operatively connected, for example, to the heating means 170, the energy storage device 130, the operating means 110, the pressure sensor, the temperature sensor, the humidity sensor, the electrical interface, and / or the display means 245, 260, so that signals can be transmitted from the overshoe 1 to the communication means 270 and back. The signals transmitted to the communication means 270 represent data that is determined in the overshoe 1 and represents, for example, status information (actual information) of the energy storage device 130 (e.g., current capacity or fill level or temperature) or the heating means 170 (e.g., current temperature of the heating means 170, current temperature of the first zone 175, current temperature of the second zone 180).The signals received by the receiving means of the communication means 265 located in the overshoe 1, however, represent, for example, information that serves as input variables for an operating state to be achieved by the overshoe 1 (target information). This is, for example, a target temperature of the heating medium 170, a target temperature of the first zone 175 or a target temperature of the second zone 180, or a target humidity within the overshoe 1. In Fig. 8, the overshoe 1 was addressed according to the illustration in Fig. 1A. However, it is understood that an overshoe 1 according to the illustration in Fig. 6 can also be provided with a communication means 265, even if this is not further illustrated in the figures.
