WORK SHOE

Description

[0001] The invention relates to a work shoe, in particular for use in leveling work and / or filling work and / or for aerating a lawn.

[0002] Work shoes of the type in question have been known in practice for years and exist in a variety of designs. For example, a shoe device in the form of a plastic spiked sole is known in the field of leveling or spatula shoes. The known spiked shoe device comprises a plastic plate with spikes as the spiked sole and is attached via straps to the existing footwear or the shoe worn by the wearer.

[0003] The known spiked shoe device is problematic in several respects. A serious disadvantage of this spiked shoe device is the considerable amount of time required to connect or couple the shoe device to the wearer's footwear using the straps. Furthermore, the shoe wearer / user is repeatedly faced with the problem that the connection required for use between the shoe worn by the wearer and the spiked shoe device is only moderately stable. Attaching the spiked shoe device to the worn shoe or footwear using straps is particularly prone to coming loose. In particular, attaching the straps using Velcro fasteners can only work with as clean and undamaged Velcro fasteners as possible.

[0004] In the common areas of application of the nail shoe device, where, for example, screed, filler, and similar materials are handled, rapid soiling is almost impossible to avoid, even with careful work. An unstable connection between the footwear and the nail shoe device caused by soiling can pose a significant risk of injury to the wearer, as they no longer have a stable footing. Consequently, there is an unnecessary risk of accidents for the wearer of the well-known nail shoe device. At the very least, the wearer of the nail shoe device must regularly consider and, if necessary, compensate for unstable footing.

[0005] Furthermore, a knee placed on the floor during physical balancing or a hand touching the fresh filler or leveling substance leads to unnecessary, costly and time-consuming additional work.

[0006] Furthermore, cleaning the conventional spiked shoe device is time-consuming and often leads to unsatisfactory results. The connection system in particular suffers from this: Either the connectors—for connecting footwear and spiked shoe device—are no longer properly cleaned because the dried-on substances can no longer be removed from the connectors or straps, or the connectors are subjected to such severe wear during thorough cleaning that the service life of the spiked shoe device is significantly reduced. Hook-and-loop fasteners or any plastic buckles wear out very quickly, requiring the entire spiked shoe device to be quickly discarded or replaced. This is costly in the long run and does not contribute to the desirable reduction of product waste.

[0007] Nail shoe devices are known, for example, from the documents US 6 223 456 B1, CN 106 136 428 A and CN 204 426 847 U.

[0008] DE 10 2010 044 816 A1 discloses a sports or work shoe consisting of a shoe upper material (shaft) which is connected via a lasting fold to an insole which is connected on its underside to an outsole, wherein for the transverse stiffening and / or longitudinal flexibility of the insole, the insole is formed from a structural sole - arranged at least in the forefoot area - and made of spring steel - or another flexurally elastic hard material - which consists of guide-like ribs directed obliquely to the longitudinal axis and substantially parallel to one another, wherein web plates are arranged at least in the area of the structural sole and the outsole connected to it, which form downward-facing plug-in, clamping or threaded projections protruding from the outsole, to which replaceable studs, spikes or other projections improving traction can be attached.

[0009] From US 9 993 045 B2 an interchangeable flip-flop sandal is known, wherein the sandal may comprise interchangeable structural features to enable a user to change the features according to a particular terrain.

[0010] The present invention is based on the object of designing and developing a work shoe of the type mentioned at the outset in such a way that one or more disadvantages of the prior art are counteracted as far as possible with simple structural means, in particular with regard to the safest and most stable stance possible during work.

[0011] According to the invention, the above object is achieved by the features of claim 1. This provides a work shoe, in particular for use in leveling work and / or filling work and / or for aerating a lawn, wherein the work shoe is designed such that a bare foot of a wearer is inserted into the work shoe via an opening and the work shoe is worn directly on the wearer's foot, wherein the work shoe is provided with downwardly projecting, elongated spacer elements, wherein the work shoe comprises a lower part and an upper part, wherein the lower part and the upper part are firmly and / or rigidly connected to one another, wherein the upper part comprises a shaft region and a base region comprising an inner base surface, which together form a receiving area for the bare foot of a wearer, wherein the upper part surrounds the bare foot of a wearer in such a way thatthat the inside of the shaft area and the inside of the base area sit directly on and engage the wearer's inserted foot, wherein the lower part is designed in the form of a base plate, wherein the downwardly projecting, elongated spacer elements are fixed to or in the base plate, wherein the upper part is open in the rear area or in the heel area, and wherein a heel strap is provided in the rear area of the upper part.

[0012] According to the invention, it has first of all been recognized that it is of considerable advantage for the wearer with regard to stable and secure support or stance during work if the work shoe is designed to be as compact and robust as possible. In a further embodiment of the invention, it has been recognized that operating complex fastening and / or coupling mechanisms for attaching nailed soles to the wearer's existing footwear is particularly disadvantageous and cumbersome, especially when stable and secure stance during work is to be ensured. According to the invention, the work shoe is designed in such a way that a wearer's foot can be inserted into the work shoe via an opening, so that the work shoe engages the inserted foot of the wearer. The work shoe can thus be worn directly on an "unshod" foot of the wearer. This means that the wearer slips his, if necessary,The sock-clad foot slides into the work shoe, establishing contact between the foot and the inside of the work shoe. The work shoe is further provided with downwardly projecting spacer elements. Preferably, the spacer elements are aligned substantially perpendicular to the underside of the work shoe, allowing the work shoe to maintain a good foothold on the surface being walked on. In other words, the work shoe can have downwardly projecting spacer elements on its underside.

[0013] Consequently, a work shoe is specified which forms a particularly compact and stable unit, so that the wearer can stand as safely and stably as possible when working.

[0014] With regard to the term "work shoe," it should be noted that—particularly within the scope of the claims and preferably within the scope of the description—a work shoe is understood to mean a shoe worn during work. Thus, according to one embodiment of the claimed teaching, a work shoe can be worn, for example, for leveling and / or filling work, whereby the downwardly projecting spacer elements of the work shoe are particularly advantageous, for example, for walking on freshly laid screed and / or when a leveling compound that has been applied needs to be aerated again. Due to the spacer elements provided in the work shoe, the wearer of the work shoe leaves no "heavy" or "disturbing" footprints in the still unconsolidated soil material. Furthermore, it is conceivable that the work shoe could be used to aerate a lawn.

[0015] The work shoe according to the invention and / or advantageous embodiments effectively address one or more problems of the prior art – such as cumbersome donning, difficult cleaning of the work shoe after use, and / or unstable / unsafe footing. Due to the compact design of the work shoe, which can be formed as a single unit, there is no need for the laborious attachment of any spiked soles and / or special extension devices to existing footwear, nor does it require the use of a complex closure device. Rather, a fully spiked shoe is provided, allowing the work shoe to be put on and taken off quickly and effortlessly.

[0016] The work shoe according to the invention and / or advantageous embodiments represent a compact system into which the wearer can simply slip on – as comfortably as a slipper. Once put on, the work shoe sits permanently and securely on the foot, thus enabling safe and targeted work. After use or after the work is done, the work shoe can be removed from the foot just as easily and quickly and, if necessary, easily cleaned. A quick hose down or a quick dip in a bucket of water, followed by a quick wipe, and the work shoe is ready for the next job.

[0017] According to the invention, the work shoe comprises a lower part and an upper part, wherein the lower part is firmly or rigidly connected to the upper part. The upper part can essentially serve to accommodate the bare foot of the wearer. The lower part can essentially serve to fix and fasten the spacer elements. Advantageously, it is conceivable for the work shoe to be made of different materials. The upper part could, for example, be made - at least partially - of a flexible material, so that, with regard to ergonomics, a suitable design and / or fit of the receiving area for the wearer's foot to be accommodated can be realized.The lower part of the work shoe, however, could be made - at least partially - of a hard and stable material, allowing the spacer elements to be suitably fixed in the lower part of the work shoe, ensuring stable support and stability of the shoe. A huge advantage of the work shoe is the permanent and / or secure connection between the upper and lower parts. This not only saves the wearer a significant amount of time compared to versions that require laborious attachment to existing footwear, but also provides the wearer with a special tool for the specific application at hand, allowing them to protect their usual work footwear.

[0018] To create a secure connection, the upper and lower parts could be glued together. It is also conceivable that the upper and lower parts could be screwed and / or riveted together. This creates a compact, unified work shoe.

[0019] In an advantageous embodiment, the upper part of the work shoe can be made at least partially of plastic, preferably a flexible elastomer. This provides a shoe that is comfortable for the wearer's foot, while also being robust and easy to clean thanks to the material.

[0020] In an advantageous embodiment, the lower part of the work shoe can be made at least partially of a hard plastic and / or aluminum. This allows the spacer elements to be mounted or fixed stably and securely in the lower part of the work shoe. Furthermore, the work shoe is made of a robust material that can easily withstand many work assignments. The work shoe thus represents a sustainable product that not only saves working time in the long term but is also cost-effective.

[0021] In a further advantageous manner, the lower part and / or the upper part of the work shoe can be constructed in multiple layers. This makes it possible to design the lower layers, especially the lower part, to be rigid and stable, allowing the spacer elements to be securely and firmly attached. The upper layers, especially the upper part, could be designed to be more flexible to ensure a comfortable foothold and the most comfortable support possible for the wearer's foot.

[0022] According to the invention, the lower part comprises a base plate.

[0023] The base plate can be rigid to ensure stability. The base plate can be made of hard plastic or aluminum, for example.

[0024] Advantageously, the lower part and / or the upper part can be cast in one or more work steps. It is also conceivable that the lower part or the base plate is embedded in the upper part, for example, during casting.

[0025] According to the invention, the spacer elements are fixed in the lower part and / or in the base plate.

[0026] Especially if the lower part and / or the base plate are made of hard plastic and / or aluminum, the spacer elements can be safely and firmly integrated into the work shoe.

[0027] In an advantageous embodiment, the spacer elements can be interchangeably fixed in the lower part and / or in the base plate. It is conceivable that the spacer elements are mounted in the lower part of the work shoe or in the base plate using a clip, snap, plug, clamp and / or screw mechanism. This allows the spacer elements to be cleverly exchanged depending on the intended use, and the work shoe can thus be adapted accordingly. As a result, the functionality of the work shoe can be variably adapted in order to be optimally equipped and equipped with suitable spacer elements depending on the surface and project. For example, the length of the spacer elements for the work shoe can be adjusted in this way. Furthermore, defective spacer elements can be replaced with new spacer elements if necessary.

[0028] In an advantageous embodiment, the spacer elements can have a visible length in the range between 20 mm and 80 mm, preferably in the range between 30 mm and 50 mm. In this context, it should be noted that the visible length can be understood as the length of a spacer element by which the spacer element protrudes from the work shoe or from the underside of the lower part of the work shoe. Consequently, the spacer elements protrude from the work shoe by a length that can be in the range between 20 mm and 80 mm. This allows the work shoe to be used particularly effectively and well for leveling work and / or filling work. Spacer elements that protrude from the work shoe by a length in the range between 30 mm and 50 mm are particularly suitable.This length is ideal for use in leveling and / or filling work, and work shoes with such spacers also provide a stable footing for the wearer of the work shoe at this height.

[0029] Advantageously, the spacers can have a maximum width between 3mm and 12mm, preferably between 5mm and 8mm. This largely prevents marks from the work shoe or the spacers in unconsolidated ground material, while simultaneously ensuring stable footing on the subsurface.

[0030] In an advantageous embodiment, the spacer elements can be cylindrical and / or conical. Thus, it is conceivable for the work shoe to have downwardly projecting spacer elements on its underside or on the underside of the lower part, which are at least partially cylindrical. Furthermore, it is conceivable for the work shoe to have downwardly projecting spacer elements on its underside or on the underside of the lower part, which are at least partially conical. Furthermore, it is conceivable for the work shoe to have downwardly projecting spacer elements on its underside or on the underside of the lower part, which are initially cylindrical in a first region and then conical towards the end region of the spacer element, which serves for support on the ground. Advantageously, the spacer elements can have a diameter in the range between 4 mm and 10 mm.

[0031] In one advantageous embodiment, it is conceivable for a spacer element to have a visible length of 35-36 mm. At the upper end of the spacer element is an approximately 8 mm long threaded rod (M8x8) for attachment to the lower part of the work shoe. The visible part of the spacer element can advantageously have a diameter of 6 mm.

[0032] In a further advantageous embodiment, it is conceivable for a spacer element to have a visible length of 35-36 mm, with the spacer element tapering to a point after approximately 28 mm. At the upper end of the spacer element is an approximately 8 mm long threaded rod (M8x8) for attachment to the lower part of the work shoe. The visible part of the spacer element can advantageously have a diameter of 6 mm before it tapers to a point.

[0033] In a further advantageous manner, the spacer elements can comprise steel pins, preferably galvanized ones. This allows a robust and durable profile of spacer elements to be realized on the underside of the work shoe or on the underside of the lower part of the work shoe using simple means.

[0034] In an advantageous embodiment, the spacer elements can be tapered, at least in the end area of the spacer element. This allows walking on fresh screed without leaving any annoying marks. Furthermore, a suitably designed work shoe can also be used particularly advantageously for aerating floors, especially lawns.

[0035] To ensure safe and stable footing for the wearer of the work shoe, the spacers can each have the same visible length, so that the undersides of the spacers, which serve as contact surfaces, define a flat support surface. This can be particularly advantageous for surfaces that are to be walked on, possibly uneven, and to which an unconsolidated leveling compound has been applied.

[0036] In an advantageous embodiment, a safety element can be provided in the area of the upper part of the work shoe. The safety element can preferably be arranged in the upper and / or frontal area of the upper part of the work shoe, so that the sensitive front area of the foot is protected. For this purpose, a steel, plastic and / or aluminum cap can be provided, for example. It is conceivable that the safety element is permanently integrated into the upper part of the work shoe. It is also conceivable that the safety element is inserted into the upper part in an exchangeable or removable manner. Consequently, occupational safety with the work shoe is significantly improved by the safety element. This aspect is particularly important when used on construction sites.

[0037] According to the invention, the work shoe or the upper part of the work shoe is designed to be open in the rear or heel area. This allows for particularly easy and quick slipping into the work shoe.

[0038] According to the invention, a heel strap is provided. In an advantageous embodiment, the heel strap can be adjusted using a snap fastener to ensure a secure fit of the work shoe on the wearer's foot. Thus, the snap fastener allows the work shoe to be optimally adjusted to the wearer's foot in a sophisticated manner. Once the work shoe is adjusted to the correct size, putting it on is virtually a simple matter of slipping it on.

[0039] In an advantageous embodiment, ventilation openings can be provided in the upper part of the work shoe. This ensures optimal ventilation of the work shoe.

[0040] The object underlying the invention is further achieved by using a work shoe according to the invention for leveling a floor, in particular a screed floor. Thus, a safe and stable footing can be ensured by using the work shoe during corresponding work applications.

[0041] The object underlying the invention is further achieved by the use of a work shoe according to the invention for aerating a lawn. Thus, a safe and stable footing can be ensured by using the work shoe during a corresponding work application, namely for aerating a lawn.
