Description

V|98U 0 000 3 9 ANTISTATIC FOOTWEAR on behalf of: JOLLY SCARPE SRL - Montebelluna (TV) Filing date: ****** This innovation offers an antistatic shoe in which there are stitchings made with an antistatic thread in the insole and sole that create an electrical connection between the foot and the tread, which is also made of antistatic material. In particular, it is possible to use the antistatic thread for the perimeter stitching that binds the upper to the insole and sole or, more preferably, it is possible to obtain one or more zigzag stitching, respectively in the insole and in the sole, thus creating sewing cords in antistatic thread that ensure this electrical contact between the foot and the ground. In the latter case, the seams made in the insole and in the sole respectively will preferably be inclined, for example orthogonal to each other, to ensure electrical contact between these two layers without the need to take extreme care in overlapping these components. Studio LIA STELLA Corso Padova, 6S 36100 VIGENZA i TALY Phone Q4 0444 / 51 96 Antistatic footwear is already known, which features devices capable of creating an electrical connection between the foot and the ground. However, these footwear are mainly used in industry and in specific work environments. In fact, there are several sectors in which workers must use antistatic footwear capable of transmitting and discharging into the ground any electrical charges accumulated during a given work period, to avoid possible accidents that can be triggered by electrostatic discharges that are released. For example, the use of this type of footwear is mandatory on oil platforms, or in numerous other environments where work is carried out in the presence of flammable or explosive materials. For this purpose, footwear is known that includes connecting means such as metal toecaps, nails or other conductive elements inserted into the sole, or copper wires or cords that start from the insole and reach the outside of the shoe, always to discharge static electricity to earth. Even if you don't operate in hazardous environments. HA STELLA studio Corso Padova. 86 36100 VICENZA-ITALY one 44 5647 ax 444 96 static electricity accumulated by the body can give This can cause a number of problems, from discomfort or headaches in more sensitive people to small shocks that can be felt, for example, when getting out of a car, or which, in some cases, can even cause damage to electronic equipment if the internal components are touched without first having taken care to ground the static electricity accumulated in the body. This innovation now fits into this sector, offering an antistatic shoe featuring one or more stitchings made of antistatic thread, with the antistatic thread in contact with the insole, and with a tread also made of material capable of grounding electricity. This way, the desired result can be achieved without affecting the aesthetics and characteristics of the shoe, and without the need for additional "ad hoc" elements, and therefore without increasing costs. This innovation will now be described in detail, by way of a non-limiting example, with reference to the attached figures in which: • figure 1 is the perspective view, partially sectioned, of a shoe according to the innovation; • figure 2 illustrates, in section, the different layers LIA STELLA studio Corso Padova, 88 36100 VICENZA - ITALY 0444)515647 ax 444 96 constituting the sole of a shoe according to the innovation; • figure 3 is the plan view of the sole of figure 2, With reference to the attached figures, the Nl indicates the upper of a shoe intended to be applied, by gluing and sewing, to a sole, for example in leather, indicated with 2, with the interposition of an insole 3. The shoe is then completed, on the outside, by a tread 4, for example in rubber or similar. To join these components together, sewing and gluing operations are used according to known technologies. In particular, the insole 3 is joined to the sole 2 using a layer of antistatic glue 5 and the sole is then glued to the tread 4 using a second layer of antistatic glue indicated with 6. The upper is also fixed to the sole using a layer of antistatic glue which affects the lower edge 7 which is turned inwards and this union can be completed using a perimeter stitching, indicated with No. 8, which binds together the turned edge 7 of the upper, the insole 3 and the sole 2. LIA STELLA studio Corso Padova, 86 36100 VICENZA - ITALY phone 044 515647 0444 / 51 960 In accordance with innovation the layers of glue 5 and or <0 6 are in glue antistatic and also the material (0 used for the tread is material antistatic. for example rubber or similar mixed with graphite. or 0> to you CXO <0 These materials are already known in the industry and therefore not a detailed description is needed. In accordance with the innovation, the shoe features at least one seam made with antistatic thread, also already known in the sector, which connects the insole with the sole 2 and the tread 4. According to a first embodiment of the present solution idea, antistatic thread can be used to make the stitching 8 which joins the upper, the insole and sole. According to a preferred form of execution thereof The solution idea will instead include one or more seams, always made with antistatic thread, in correspondence with a central area of ​​the insole, thus ensuring perfect continuous contact between the foot and the underlying layers. For example, it will be possible to provide a zigzag stitching indicated with 9 in the insole, and one or more zigzag stitchings, always in antistatic thread, in the sole, corresponding to the stitching 9 of the insole. With this configuration the sole of the foot will be in contact with the seam 9 which creates electrical contact with the antistatic glue layer 5 which in turn is in contact with the seams 10 in the sole, which in turn are in contact with the antistatic glue layer 6 and with the antistatic tread 4, Seams 9 and 10 may be parallel or, preferably, orthogonal, so as to ensure overlap and contact between them, without the need to take precise care of the position of these seams. This creates a shoe that can be used both at home and in the office, which can be produced with current technologies without the need for particular interventions and modifications and which constantly creates electrical contact between the foot and the ground, allowing accumulated static electricity to be discharged to the ground. Within the same solution idea, any detailed variations may then be envisaged, without thereby departing from the scope of protection of the present invention. The dimensions, as well as the materials used, may also vary depending on the application requirements. Studio LA fbLLA Corso Podova, 86 36100 VICENZA - ITALY Phone 0444 / 515647 444 / 5 5960
