Abstract

Shoe with slipper function both open and closed, of the type realised by means of perimetrical sewing ( 3 ) of the upper ( 2 ) on the sole ( 1 ), having the following characteristic: I-use of an elastically yielding flexible expanded plastic material sheet with alternatively variable thickness >2 mm and <8 mm, pierced (F) and bossed on its surface (e) and ribbed (i) on the opposite surface, the piercings being made in the thinness zones and then alternated by bossings (e); II-punching of said sheet in soles ( 1 ) and uppers ( 2 ); III-perimetrical sewing at the sole edge ( 3 ) of the upper ( 2 ) to the sole ( 1 ); IV-with the characteristic that said bossings (c) are placed towards the outside of the shoe both for the sole ( 1 ), thus toward the, floor, and for the upper, thus towards outside.

Description

Footwear.

objective

The present invention relates to a shoe according to the preamble of the main claim.

Use

The destination is footwear, substantially but Not exclusively for domestic use.

Prior art

In the current state of the art the use of footwear for domestic use, for example, slippers, both open and closed type (for example, standing complete), for domestic use, use at home, in hotels or in rooms, etc.

Without excluding, however, use in an environment of smooth and comfortable floors, for example, in swimming pools, etc.

In general, said shoes or slippers (in the present description the term slippers refers to both that are open behind in the heel, as well as those are closed from behind, like shoes for full foot) are fabric, both to make it easier to put them on and to compensate perspiration.

US Patent No. 3,311,937 discloses a footwear serving as the basis for claim 1.

Drawbacks

Existing types of shoes exceed these problems, but they are expensive and their intended use is limited. By For example, you cannot use fabric slippers in pools, etc.

Object of the invention

The object of the invention does not consist only in making an economic shoe, but also in a  Comfortable, breathable, lightweight, non-slip, anti-mold shoe (germs easily root in tissues or clothing).

The problem is solved by characteristics of the main claim.

Subordinate claims represent Preferred solutions.

Advantages

In this way, the following are achieved advantages:

-

A lower cost together with a quality acceptable for use destined;

-

Breathability, thanks to perforation multiple on the sole as well as on the outside of the sole;

-

Antisudor, thanks to the presence of the light interior ripple (which is derived from the nerves of the mesh polyester) that prevents full contact with the leather;

-

Flexibility and deformation, thanks to spongy effect of expanded plastic material;

-

Resistance, thanks to the PVC material expanded that has been used with polyester mesh;

-

Anti-slip, thanks to outer bulge, which also extends to the sole in its underlying surface;

-

Anti-mold thanks to the type of material and antibacterial treatment;

-

Heat resistance, thanks to the type of material used, up to 80 ° C;

-

Ecological, thanks to the material no pollutant;

-

Elastic, thanks to the spongy effect of the material.

Detailed description of an embodiment

An explanation will be provided below. in greater detail of the invention, referring to the attached figures, in which:

Figure 1 represents a perspective view of a shoe open from behind;

Figure 1A represents a section in section expanded of the individual material that constitutes the shoe and that, once sewn, it constitutes the shoe as much as a sole as a shovel, since there is no differentiation of said shoe between sole and shovel.

Detailed description of the figures

As can be seen in the figures, that they represent the open shoe (but obviously also could be closed to contain the heel), it is used only an expanded PVC sheet material with polyester mesh, perforated (F) and domed (e) on a surface and wavy (i) in the opposite surface (see Figure 1A), as a base material obtained according to the technical comments of the realization on Expanded perforated and nonwoven flexible materials domed

The sole-shaped sheet (1) is cut and in outer sole shape (2) and the blade (2) is sewn (3) on top of the sole (1) as is known in the art, but ensuring that the domed surface (and) is oriented outward, and so both provided under the sole (1) and above the blade (2).

In this way, very simply and economic the shoe is obtained, which as a result is perforated  (F) on both the shovel (2) and the sole (1) and is therefore perfectly breathable, non-slip, etc., as it has been previously mentioned.

Perimeter seam (3) is extended throughout the edge of the sole (1) and also beyond the blade (2). From this way, you get more strength and endurance from the shoe.

Advantageously, sewing is also performed at along the free edge of the blade (21). In this way, it is conferred to the shoe a greater resistance, therefore avoiding the elongation of the material when forcing the instep.

Advantageously, before sewing perimeter, a piece of tissue is applied to cover over and below the edge or the edges that are destined to join, or of the only edge destined to be reinforced. In this way, it Provides the advantage of reinforcing footwear. Therefore there is the advantage of having a more rounded and resistant shoe under the perimeter structure of the piece with the seam respective (the solution is not illustrated but is clearly predictable and known to those skilled in the art of reinforcing the seam and edges of deformable non-woven materials and flexible). Advantageously, the material is subjected to a surface treatment that contains a mold protection known in the art.

In order to obtain the desired section of the material the following parameters will apply: thickness alternatively variable between> 2 mm and <8 mm. Advantageously, the maximum thickness is between 5 and 6 mm

Claims (5)

1. Footwear with shoe function both open and closed, of the type made by a perimeter seam (3) of the blade (2) on the sole (1), characterized in that it has the following characteristics:

i)

use a sheet of expanded plastic material, flexible elastically deformable with an alternately thickness variable between> 1 mm and <8 mm, perforated (F) and domed in its surface (e) and with nerves (i) on the opposite surface, drilling in the finest and alternate areas later by means of bulges (e);

ii)

punch said sheet into soles (1) and shovels (2);

iii)

the perimeter connection at the edge (3) of the sole from the shovel (2) to the sole (1);

iv)

with the characteristic that said bulges (e) are arranged towards the outside of the footwear for both the sole (1), therefore towards the ground, as for the shovel, so both outward.

2. Footwear according to claim 1, characterized in that said minimum thickness is> 2 m and the maximum is between 5 and 6 mm. 3. Footwear according to any of the preceding claims, characterized in that the perimeter seam is extended over the entire edge of the sole (3). 4. Footwear according to any of the preceding claims, characterized in that sewing is also carried out along the free edge of the blade (21). 5. Footwear according to any of the preceding claims, characterized in that before performing the perimeter seam, a piece of fabric is applied to cover above and below the edge / s intended to be joined or not.
