Abstract

A sandal (100, 100 ', 100 ") comprising a bottom (11) and a shaft (10) connected to the bottom (11), the bottom (11) comprising a toe area (12), a heel area (13), an inner edge (14) and an outer edge (15), - wherein the outer edge (15) of the bottom (11) at the human foot tightened sandal (100) from the little toe to the heel and the inner edge (14) from the heel to extends to the big toe, characterized in that- the bottom (11) via its inner edge (14) is connected to the shaft (10), - the shaft (10) only partially covers the respective back of the foot (17) when the sandal (100) is pulled on while leaving a free space (20) between a lateral outer edge (21) of the shank (10) and the outer edge (15) of the bottom (11), - and that the shank (10) is at least partially resiliently elastic.

Description

• - wobei der Boden einen Zehenbereich, einen Fersenbereich, einen Innenrand und einen Außenrand aufweist,
• - und wobei der Außenrand des Bodens bei am menschlichen Fuß angezogener Sandale sich von Kleinzehen über Kleinzehenabziehermuskel bis zur Ferse und der Innenrand von der Ferse bis zum Großzehen erstreckt.

The invention relates to a sandal comprising a bottom and a shaft connected to the ground,

• the floor having a toe area, a heel area, an inner edge and an outer edge,
• - And wherein the outer edge of the soil in sandals attracted to the human foot extending from small toe on Kleinzehenabziehermuskel to the heel and the inner edge of the heel to the big toe.

Known sandals are characterized by a variety of variants, of which some, such as Schrägriemen-, Kreuzriemen-, cross-belt and thong sandals or Roman and wooden sandals are mentioned. As beach sandals toe thong sandals are often worn without or with very flat heel. In all known sandals, the shaft parts, such as belts, are connected at least at two points opposite to the edge regions at the inner edge and at the outer edge of the base.

The 1 shows a typical prior art slipper sandals 1, with an arcuate shaft 2, which is permanently connected to a bottom 11 on both sides. The shaft 2 has two recesses 3 tapering towards the top of the shaft.

The object of the invention is to design a novel sandal, especially for leisure activities, which stands out in terms of construction and shape of known sandals.

• - Der Boden ist über seinen Innenrand mit dem Schaft verbunden;
• - Der Schaft deckt bei angezogener Sandale nur teilweise den jeweiligen Fußrücken ab, bei Belassung eines Freiraumes zwischen einem seitlichen Außenrand des Schaftes und dem Außenrand des Bodens;
• - Der Schaft ist wenigstens teilweise federnd elastisch.

According to the invention, a sandal mentioned in the preamble has the following features:

• - The floor is connected via its inner edge with the shaft;
• - When the sandal is worn, the shaft only partially covers the respective back of the foot, leaving a free space between a lateral outer edge of the upper and the outer edge of the bottom;
• - The shaft is at least partially resiliently elastic.

The fact that the space between a lateral outer edge of the shank and the outer edge of the floor extends along the entire outer edge of the floor, creates for observers the first impression that the sole "hanging in the air". In fact, however, the shaft is positively or materially connected to a part of the sole, namely at a central portion of the inner edge.

It is expressly pointed out that the sandal according to the invention is not a sturdy footwear for long walks and hikes, but a slipper sandal.

In the shaft, at least one resilient elastic stiffening element can be installed, which yields when donning the sandal on the human foot and slightly presses against the back of the person wearing the sandal, so that the sandal gives a certain support.

The grip can also improve a toe bridge, which connects the ground with the shaft, also leaving the free space between the lateral free outer edge of the shaft and the outer edge of the floor.

Preferably, the stiffening element of the shaft is in the form of a built-in shaft shank. The flat structure may for example be an intermediate layer of a thin, resilient metal sheet or a resilient grid structure.

In a preferred embodiment, the sandal can be made entirely of thermoplastic material by the two main parts, d. H. the bottom and the shank are joined together in joining processes, for example by welding or gluing. Particularly advantageous is a massive version of the sandal has proven. Accordingly, the sandal in a piece of material, for example by injection molding of PE molding compound, polyurethane rubber, SBR (styrene-butadiene rubber) or other elastomers may be made. It is also possible to make the massive sandal with the help of a 3D printer.

An integral plastic (integral foam) comes into question by the shaft different degrees of hardness, z. B. has a decreasing in the direction of the outer edge of the shaft hardness.

The soil can be massive or multi-layered. In both cases, the floor can have a flat or structured surface or insole with hollows and / or elevations, in particular adapted to the anatomical shapes of the human foot.

On the shaft any ornamental elements, for example, by embossing, perforations or reflective images may be introduced. On the surface of the shaft, an exchangeable release layer can be adhered, which can be removed as needed by the user and replaced by another. Such, for example, foil-like release layer can with printed image or any design be provided. The exchangeable release layers can be offered as an addition to the sales product (sandal).

The principle of the exchangeable release layer can be used with all sandals variants and also with other shoes, for example with sports shoes.

Furthermore, the shaft may have braided or net-like structures.

The same or similar elements may be provided in the following figures with the same or similar reference numerals. Furthermore, the figures of the drawing, the description and the claims contain numerous features in combination. It is clear to a person skilled in the art that these features are also considered individually or that they can be combined to form further combinations not described here in detail.

The 3 and 6 show a sandal 100 according to the invention, comprising a shaft 10 and a floor 11 , The floor 11 has a toe area 12 , a heel area 13 , an inner edge 14 and an outer edge 15 on, with the shaft 10 the anatomical design of the human foot back 17 is correspondingly arched. This is for example the 2 . 5 . 6 and 9 refer to.

The shaft 10 only partially covers the back of the foot when the sandal is on 17 from (cf. 2 and 5 ) and forms a free space 20 between a lateral outer edge 21 of the shaft 10 and the outer edge 15 of the soil 11 out. As the 6 shows is the shaft 10 in a middle area 23 of the inner edge 14 with the ground 11 connected or goes into the ground 11 above. The sandal 100 is in a piece of material made of non-toxic plastic, in the present case made of PUR rubber by injection molding.

In 2 . 4 and 7 is a sandal 100 ' shown, which differs from the already described sandal 100 by the presence of an additional element, namely a toe bridge 16 different. The thong 16 connects the sole (the ground 11 ) with the shaft 10 , On the shaft 10 are heart-shaped decorative elements 18 (see. 2 to see).

The 5 shows a matching pair of sandals 100 ' with thong 16 and a heel-side strap 19 , The sandal 100 ' has a net-like shaft 10 , which with the belt 19 is color coordinated and structurally. From the 5 it can be seen that the outer edge 15 of the soil 11 from small toe to heel and the inner edge 14 extends from the heel to the big toe.

The sandal 100 ' with straps 19 is also in 8th shown. The belt 19 is a closure, here: Velcro 24 with the shaft 10 connectable.

According to 10 has the shaft 10 via a stiffening element 22 which preferably - forming a middle intermediate layer - consists of resilient, thin sheet steel. The stiffening element 22 is covered on both sides by a synthetic leather fleece.

In 11 is a foil-like release layer 25 when removing or sticking on the shaft 10 shown. The release layer 25 settles with its lower surface 26 , which is coated with a release adhesive known per se, remove several times and stick.
