Description

WORK SHOE

The invention relates to a work shoe, in particular for use in leveling work and / or filling work and / or for airing a lawn.

Work shoes of the type in question have been known from practice for years and exist in a wide variety of designs. For example, a shoe device in the form of a plastic nail sole is known from practice in the field of leveling or spatula shoes. The known nail shoe device comprises as a nail sole a plastic plate which is provided with nails and is fastened via straps to the existing footwear or to the worn shoe of a Schuhträ gers.

The known nail shoe device is problematic in several respects. A serious disadvantage of this nail shoe device is first of all the high expenditure of time that is required to connect or couple the shoe device to the wearer's footwear via the straps. Furthermore, the shoe wearer / user is repeatedly faced with the problem that the connection to be made between the shoe worn by the wearer and the nail shoe device is only moderately stable. The attachment of the nail shoe device via straps on the shoe being worn or on the footwear tends to be very particular to loosen. In particular, fastening the straps using Velcro can only work with the cleanest possible and undamaged Velcro.

In the common areas of application of the nail shoe device, where, for example, screeds, putty and similar materials are handled, rapid soiling can hardly be avoided - even if you work carefully. An unstable connection between the footwear and the nail shoe device associated with the contamination can mean a considerable risk of injury for the wearer, since he no longer has a firm footing. Consequently, there is an unnecessary accident risk for the wearer of the known nail shoe device, At least, however, the wearer of the nail shoe device has to regularly take into account an unsafe situation and, if necessary, compensate for it.

Furthermore, a knee that is put down in the course of physical balancing or a hand touching the fresh compound in the fresh filler or leveling substance leads to unnecessary, costly and time-consuming additional work.

Furthermore, the cleaning of the known nail shoe device is time-consuming and regularly does not lead to satisfactory results. The connection system in particular suffers in particular: Either the connecting means - for coupling the footwear and the nail shoe device - are no longer properly clean because the dried-on substances can no longer be removed from the connecting means or belts, or the connecting means are thorough cleaning is so stressed that it significantly reduces the service life of the nail shoe device. Velcro fasteners or any plastic buckles wear out very quickly, which means that the entire nail shoe device must be discarded or replaced quickly. This is costly in the long run and not in the sense of a desirable waste avoidance of the products.

The present invention is therefore based on the object of designing and developing a work shoe of the type mentioned in such a way that one or more disadvantages from the prior art are counteracted as far as possible using simple structural means, in particular with regard to the most secure and stable state possible Labor input.

According to the invention, the above object is achieved by the features of claim 1. According to this, a work shoe, in particular for use in leveling work and / or filling work and / or for ventilating a lawn, is specified, the work shoe being designed in such a way that a wearer's foot can be introduced into the work shoe via an opening, and the Ar is provided with downwardly protruding spacer elements. In the manner according to the invention, it has first of all been recognized that it is of considerable advantage for the wearer in terms of a stable and secure hold or standing during work if the work shoe is designed as compact and robust as possible. In a further way according to the invention it has been recognized that operating complex locking and / or coupling mechanisms for attaching nail soles to the wearer's existing footwear is particularly disadvantageous and cumbersome, especially when a stable and secure stance must be ensured during work . In accordance with the invention, the work shoe is designed in such a way that a foot of a wearer can be introduced into the work shoe via an opening, so that the work shoe engages the foot of the wearer that has been introduced. This means that the work shoe can be worn directly on an “unshod” foot of the wearer. This means that the wearer slips his foot, possibly clad with socks, into the work shoe, and contact is established between the foot and the inside of the work shoe. The work shoe is also provided with downwardly protruding spacer elements. Preferably, the spacer elements are aligned essentially perpendicular to the underside of the work shoe, so that the work shoe can stand properly on the ground to be walked on. In other words, the work shoe can have stand elements protruding downward on its underside.

Consequently, a work shoe is specified which forms a particularly compact and stable unit, so that the wearer can stand as securely and as stable as possible during work.

With regard to the expression “work shoe”, it should be noted that - in particular within the scope of the claims and preferably within the scope of the description - a work shoe is to be understood as a shoe that is worn during work. For example, a work shoe according to an embodiment of the claimed teaching can be worn for leveling work and / or filling work, with the downwardly protruding spacer elements of the work shoe being of particular advantage, for example to step onto a freshly laid screed and / or when a leveling compound has been applied again must be ventilated. Due to the spacer elements provided in the work shoe the wearer of the work shoe does not leave any “heavy” or “annoying” footprints in the as yet unsecured floor material. It is also conceivable that the work shoe is used to air a lawn.

The work shoe according to the invention and / or advantageous embodiments counteract one or more problems from the prior art - such as awkward putting on, difficult cleaning of the work shoe after use and / or an unstable / unsafe stance - sovereignly. Due to a compact design of the work shoe, which can be formed as a unit, there is consequently no need for cumbersome attachment of any nail soles and / or special extension devices to existing footwear and no complex locking device has to be used. Rather, a complete nail shoe is provided, so that the work shoe can be put on and taken off quickly and easily.

The work shoe according to the invention and / or advantageous embodiments represent a compact system into which the wearer - comfortably like in a house shoe - can simply slip. Once put on, the work shoe is permanently stable on the foot and can thus enable safe and targeted work. After use or after work, the work shoe can be removed from the foot just as easily and quickly and, if necessary, cleaned with ease. Briefly hosed with the hose or dipped quickly into a bucket of water, then rubbed off briefly and the work shoe is ready for the next job.

In an advantageous manner, the work shoe can include a lower part and an upper part, the lower part being firmly or rigidly connected to the upper part. The upper part can essentially serve to accommodate the unshod foot of the wearer. The lower part can essentially serve to fix and fasten the spacer elements. It is advantageously conceivable that the work shoe is made of different materials. The upper part could for example - at least partially - be made of a flexible material, so that with regard to ergonomics, a suitable design and / or fit of the receiving area for the foot of a wearer to be received is possible can be realized. The lower part of the work shoe, however, could - at least partially - be made of a hard and stable material, so that the spacer elements can be fixed in a suitable manner in the lower part of the work shoe and a stable hold and stand of the shoe can be achieved. An enormous advantage of the work shoe is that there is a permanent and / or fixed connection between the upper part and the lower part. This not only saves the wearer a considerable amount of time compared to variants that have to be awkwardly attached to footwear in IN ANY. At the same time as the work shoe, the wearer has special work equipment for the specific purpose at hand and can protect his normal work shoes.

The upper part and the lower part could be glued to one another in order to achieve a permanent connection. It is also conceivable that the upper part and lower part are screwed and / or riveted to one another. Thus, a compact and a unitary work shoe can be produced.

In an advantageous embodiment, the upper part of the work shoe can be at least partially taken from plastic, preferably from a flexible elastomer. It is thus possible to provide a shoe which is comfortable for the foot of a wearer to wear and which, due to the material, is both robust and easy to clean.

In an advantageous embodiment, the lower part of the work shoe can be made at least partially from a hard plastic and / or aluminum. Thus, the spacer elements can be stably and securely mounted or fixed in the lower part of the work shoe. Furthermore, the work shoe is made from a robust material that can withstand many work assignments with ease. The work shoe is a sustainable product that not only saves working time in the long term, but is also cost-efficient.

In a further advantageous manner, the lower part and / or the upper part of the work shoe can be constructed in several layers. It is thus possible to design the lower layers, in particular the lower part, to be correspondingly rigid and stable, so that the spacer elements can be attached securely and firmly. The upper layers, especially the upper part, could be made more flexible to achieve a comfortable stand or the most comfortable possible reception for the wearer's foot.

In an advantageous embodiment, the lower part can include a base plate. The base plate can be rigid with a view to a stable stand. The base plate can be made of hard plastic or aluminum, for example.

In an advantageous manner, 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 - for example during casting - is let into the upper part.

The spacer elements can advantageously be fixed in the lower part and / or in the base plate. In particular, if the lower part and / or the base plate are made of hard plastic and / or aluminum, the stand element can be safely and securely integrated into the work shoe.

In an advantageous embodiment, the spacer elements can be fixed in an exchangeable manner 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 via a clip, latch, plug, clamp and / or screw mechanism. Thus, the spacer elements can be exchanged in a clever way depending on the application and the work shoe can be adjusted accordingly. As a result, the functionality of the work shoe can be variably adapted, namely to be optimally equipped and equipped with appropriately suitable spacer elements depending on the ground and the project. For example, the length of the spacer elements for the work shoe can be regulated in this way. Furthermore, any defective spacer elements can be replaced with new spacer elements.

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 un- The visible length can be understood to be 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. As a result, the spacer elements protrude from the work shoe by a length which can be in the range between 20mm and 80mm. The work shoe can thus be used particularly effectively and effectively for leveling work and / or filling work. Spacer elements that protrude from the work shoe by a length between 30mm and 50mm are particularly suitable. This length is ideal for use in leveling work and / or filling work and work shoes with such spacer elements at this height also provide a stable stand for the wearer of the work shoe.

In an advantageous manner, the spacer elements can have a maximum width in the range between 3mm and 12mm, preferably between 5mm and 8mm. In this way, traces of the work shoe or the spacer elements in a ground material that is not yet firm can be largely avoided and, at the same time, a stable stand on the ground can be made possible.

In an advantageous embodiment, the spacer elements can be cylindrical and / or conical. Thus, it is conceivable that the work shoe on its underside or on the underside of the lower part has downwardly ra lowing spacer elements 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 spacers are at least partially conical. Furthermore, it is conceivable that the work shoe on its underside or on the underside of the lower part has downwardly projecting spacer elements that are initially cylindrical in a first area and toward the end area of the spacer element, which is to rest on the ground serves, then forms are conical out. Advantageously, the spacer elements can have a diameter in the range between 4mm and 10mm.

In the context of an advantageous embodiment, it is conceivable that a spacer element has a visible length of 35-36 mm. At the top of the Stand element is an approx. 8mm long threaded rod (M8x8) for fastening in the lower part of the work shoe. The visible part of the spacer element can advantageously have a diameter of 6 mm.

In the context of a further advantageous embodiment, it is conceivable that a distance element has a visible length of 35-36mm, the distance selement tapering to a point after approximately 28mm. At the upper end of the spacer there is an approx. 8mm long threaded rod (M8x8) for fastening in the lower part of the work shoe. The visible part of the spacer element can - before it tapers to a point - advantageously have a diameter of 6 mm.

In a further advantageous manner, the spacer elements, preferably zinc-plated, comprise steel pins. Thus, a robust and resistant profile of spacer elements on the underside of the work shoe or on the underside of the lower part of the work shoe can be realized with simple means.

In an advantageous embodiment, the spacer elements can be designed to taper to a point, at least in the end region of the spacer element. This means that fresh screeds can be walked on without leaving any disturbing marks. Furthermore, a correspondingly designed work shoe can also be used particularly advantageously for ventilating floors, in particular a lawn.

With regard to a safe and stable stand for the wearer of the work shoe, the spacer elements can each have the same visible length, so that the undersides of the spacer elements used to rest on the floor define a flat support surface. This can be particularly advantageous for surfaces that are to be walked on, possibly uneven, on which a leveling compound that has not yet been consolidated has been applied.

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, for example, a steel, plastic and / or aluminum nium cap be provided. It is conceivable that the safety element is firmly integrated into the upper part of the work shoe. It is also conceivable that the safety element is replaceably or removably inserted into the upper part. As a result, work safety with the work shoe is significantly improved by the safety element. This aspect is particularly important when used on construction sites.

In an advantageous embodiment, the work shoe or the upper part of the work shoe can be designed to be open in the rear area or in the heel area. This enables particularly easy and quick slipping into the work shoe.

In an advantageous embodiment, a heel strap can be provided, where the heel strap can be regulated by means of a push button in such a way that a firm fit of the work shoe on the wearer's foot can be achieved. In this way, the work shoe can be optimally adapted to the wearer's foot using the push button. Once the work shoe has been adjusted to the correct size, putting on the work shoe is all about simply slipping it on.

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

The object on which the invention is based is furthermore achieved by using a work shoe according to the invention for leveling a floor, in particular a screed floor. In this way, a safe and stable stance can be guaranteed by using the work shoe when working accordingly.

The object on which the invention is based is also achieved through the use of a work shoe according to the invention for aerating a lawn. Since with a corresponding work, namely to ventilate a Lawn, a safe and stable stand can be guaranteed by using the work shoe.

There are now various possibilities for designing and developing the teaching of the present invention in an advantageous manner. For this purpose, on the one hand, reference is made to the claims subordinate to claim 1 and, on the other hand, to the following de explanation of preferred embodiments of the invention with reference to the drawing.
