Description

The present invention relates to a method for producing a weather-resistant straw shoe and a corresponding weather-resistant straw shoe.

Conventional straw shoes have disadvantages in terms of their durability, comfort, especially in winter weather (snow, rain, cool temperatures) and usability on consecutive days in wet weather, which lead to limited functionality, durability and solidity.

the CN 2 170 656 Y describes a weather-resistant straw shoe with a leather inner lining, which is not made waterproof. from de U.S. 2018/0 352 905 A1 is a waterproof shoe with an inner shoe - but with a woven upper. The US patent U.S. 1,035,496 A discloses a breathable, natural fiber-based shoe with a McKay-style stitched sole and severely limited weather resistance. In the German patent DE 605 825 A describes a shoe with an upper made of raffia and a sole made of solid material, which is suitable all year round but does not provide a waterproof inner shoe. US patent U.S. 6,701,641 B2 shows a liner for a waterproof shoe, unrelated to straw shoes. The European disclosure document EP 2 952 113 A1 discloses a shoe manufacturing process with a PVC coating for sealing, but also in a non-straw shoe context.

In the case of known straw shoes of the type mentioned at the outset, the problems of rapid soaking occur, particularly in snowy and rainy weather. Feet get wet and cool down faster. If you then want to put the straw shoes back on the following day, they are usually not completely dry and the wearer quickly gets cold feet.

The object of the present invention is to provide a method for producing a weather-resistant straw shoe and a corresponding weather-resistant straw shoe, which eliminates the above disadvantages and problems.

The present invention solves this problem with the features of claim 1.

The present problem is solved according to the present invention in particular by providing a method for producing a weather-resistant straw shoe and a corresponding weather-resistant straw shoe which has a rubber sole and a waterproof inner shoe bonded to a soft inner material.

Further configurations and developments of the present invention result from the dependent claims.

The present invention is described below with reference to the drawings and explained in more detail by them.

1 shows a top view of a straw shoe blank 1. This is preferably made from at least one braided strand 2 of Lafite straw with a light-colored sewing thread. Alternatively, corn, rye, wheat and/or bast straw can also be used. The straw blank 1 is made by hand according to shoe last dimensions. The braided strands of straw 2 are sewn together row by row by hand. The straw shoe blank has a slip opening 3 . 1a shows the straw shoe blank 1 1 in side view. The straw shoe blank 1 is preferably impregnated, For example, it is coated with a thin layer of adhesive to increase durability.

In 2 1 is shown a plan view of a rubber sole 4 for a straw shoe for explaining manufacture according to an embodiment of the present invention. In a further manufacturing step, a prefabricated outsole 4 is sewn on with a sewing machine. The waterproof sole 4 is preferably a black rubber sole, which preferably has a profile according to 2a in order to achieve the best possible adhesion to the ground even in snow/mud and adverse weather conditions. This rubber outsole 4 is made using a sewing machine with a light-colored thread, in particular the same thread as the straw shoe blank 1 according to FIG 1 , sewn to the straw shoe blank at an edge of the sole 4 projecting upwards over the sole. In order to increase the adhesion between the sole 4 and the straw shoe blank 1 - also with regard to damp weather and wet conditions - the sole 4 is preferably additionally glued.

3 shows a blank 5 for an inner shoe 6 for the straw shoe made, for example, of dark plush material, in particular an artificial fur. The plush material can have a coating, in particular made of Teflon. A non-woven fabric can also be used instead. A waterproof PVC film is cut to size (not shown) to seal the straw shoe to the foot. To produce the inner shoe 6 , the blanks of the two materials (waterproof film and plush material) are first connected using a cold-adhesive process and glued to form an inner shoe 6 . The waterproof PVC foil serves to make the shoe waterproof.

In 4 the inner shoe 6 in the straw shoe blank 1 is shown in a side view and the slip opening 3 of the shoe is still unprocessed. The inner shoe 6 is manufactured with regard to its dimensions using a shoe last. It is fixed in the straw shoe, in particular with an adhesive. The PVC film of the inner shoe 6 is not sewn, otherwise it would be damaged by the thread holes and a consistent water seal would be at risk.

Out of 5 a commercially available, preferably cushioning or shock-absorbing insole 7 can be seen. This is for comfort. The insole 7 is preferably made according to the same inner material as the inner shoe 6 made of artificial fur 5a or non-woven provided, in particular glued. 5b shows the removable insole 7 in relation to the straw shoe in which it is inserted.

6 shows the finished, waterproof straw shoe with a nylon band 8, which is sewn on, preferably by hand, around the upper edge of the slip opening 3 of the straw shoe, preferably overlapping both inside and outside in a U-shape. In this way, the inner shoe 6 and the straw shoe blank 1 are additionally fixed and reinforced at the slip opening 3, which is subjected to greater stress by putting on and taking off.

Although the present invention has been described with reference to a specific embodiment, it is not limited thereto but can be modified in many different ways. In particular, the concrete proportions and material suggestions are only to be seen as examples. In particular, the waterproof film can also be made from another waterproof or water-repellent material instead of PVC, for example a breathable “climate membrane” such as Symphatex®, Gore-Tex® or the like. Instead of the nylon strap, another material, in particular a leather piping, can also be sewn.
