Description

Zaščitna rokavicaProtective glove

Predmet izuma je zaščitna rokavica, kije prednostno namenjena za delo s pločevino v preoblikovani in odrezovalni industriji, ter v varilstvu. Nadalje je rokavica uporabljiva v gradbeništvu in pri drugih delih, pri katerih so roke podvržene mehanskih, toplotnim, kemijskim in tekočinskim nezaželenim obremenitvam.The subject of the invention is a protective glove, preferably intended for use with sheet metal in the transformed and cutting industry, and in welding. Furthermore, the glove is useful in construction and other parts where the hands are subjected to mechanical, thermal, chemical and liquid unwanted loads.

Predmet izuma spada v razred A 41 D 13/10 mednarodne patentne klasifikacije.The subject matter of the invention is in Class A 41 D 13/10 of the International Patent Classification.

Pričujoči izum rešuje problem pri zaščitnih rokavicah in sicer kako naj rokavica ne povzroča upora pri prijemanju, da ohrani uporabnik prijemni občutek pri isti prijemni sili roke, naj zdrži na dlani in na prstih na strani dlani vrezno obremenitev, ki je simulirana s testnim poizkusom v obliki potega roba pločevine, določene debeline, v določeni dolžini in z določeno silo, ter naj zaščitno sredstvo v rokavici v slučaju dotika s tkivom roke v slučaju poškodbe, ki jo povzroči obremenitev, ki presega predpisano največjo in za katero je rokavica testirana, ne povzroči dodatne poškodbe oz. zastrupitve tkiva, pri čemer naj bo rokavica taka, da bo tudi ščitila pred kratkotrajno temperaturno bremenitvijo okoli 500° C, ter jo bo moč izdelovati po znanih postopkih in na znanih strojih za krojenje in šivanje.The present invention solves the problem of protective gloves, namely, how the glove should not cause a grip resistance to maintain the wearer's sensation at the same gripping force of the hand, to hold the notch load simulated by a test experiment in the form of a test experiment in the form of pulling the edge of the sheet, of a certain thickness, at a certain length and with a certain force, and the protective glove in the case of contact with the tissue of the hand in the event of damage exceeding the prescribed maximum and for which the glove has been tested, should not cause additional injuries or injuries. tissue poisoning, with a glove that protects against short-term temperature load of about 500 ° C and can be made by known procedures and by known cutting and sewing machines.

Znane zaščitne rokavice so izdelane iz usnja različne obrabne odpornosti, pri čemer so na dlani večslojne. Te rokakvice zdržijo sorazmerno majhno vrezno obrementitev.The well-known protective gloves are made of leather of different wear resistance, with multilayered palms on the palms. These gloves withstand a relatively small notch load.

Nadalje so znane rokavce, ki vsebujejo med dvema usnjenima slojema zaščitno jekleno mrežo.Further known are sleeves containing a protective steel mesh between two leather layers.

Pomanjkljivost teh rokavic, kljub njihovi dobri zaščitni lastnosti, je v njihovi togosti. Za prijem je potrebna velika sila, ki pri mnogokratnem postopku (delu) prekomerno utruja in izčrpava uporabnika.The disadvantage of these gloves, despite their good protective properties, is their rigidity. The grip requires a great deal of force, which in many cases (work) over-tired and exhausts the user.

Nadalje je pomanjkljivost teh rokavic v tem, da ne nudijo finega prijemnega občutka. Zato se zgodi, da lahko npr. ploščati predmeti, ki jih držimo le na osnovi trenja, zdrsnejo iz prijema. Ta pomanjkljivost se zlasti kaže kot nevarna pri ročnem vstavljanju in pozicioniranju obdelovancev v stroj.Furthermore, the disadvantage of these gloves is that they do not offer a fine grip. So it happens that e.g. flat objects that are held solely on the basis of friction slip from the grip. This defect is particularly dangerous in the manual insertion and positioning of workpieces into the machine.

Praksa je pokazala, da se po dolgotrajni uporabi takih rokavic lahko nekatere žice mreže zaradi mnogokratnega pregiba prekinejo. Posamezni konci teh žic predrejo notranje plasti rokavice in mehansko poškodujejo uporabnika, znano je, da nastopi tudi zastrupitev.Practice has shown that after prolonged use of such gloves, some wires of the net may be broken due to repeated bending. The individual ends of these wires penetrate the inner layers of the glove and mechanically damage the wearer, and poisoning is known to occur.

Vse opisane rokavice so neodporne proti kemikalijam in električnem toku, za kar so predvidene druge, prednostno gumene rokavice, ki pa nimajo mehanskih zaščitnih lastnosti.All gloves described are chemical and electrical resistant, which is intended for other, preferably rubber gloves, which do not have mechanical protective properties.

Prava tako prepuščajo tekočine, kar je pomanjkljivost pri delu z namaščeno pločevino.They also allow liquids to pass through, which is a disadvantage when working with greased sheet metal.

Iz povedaneg sledi, da ne obstajajo rokavice, ki bi nudile vse vrste zaščitnih lastnosti, kot smo jih navedli v tehničnem probelmu.It follows from the above that there are no gloves that offer all kinds of protective properties, as we have stated in the technical problem.

Tehnični problem je rešen z izumom tako, da je rokavica ukrojena in sešita iz večslojnega materiala in sicer iz mehanskega zaščitnega sloja, ki sestoji iz mreže poliolefinskih ali aramidnih vlaken (Kevlar®), na eni njegovi strani iz vezno izolativnega sloja, ki sestoji iz silikona ini/ali poliuretana, na drugi strani zaščitnega sloja, ki je predviden za naleg neposredno na kožo in ki je bombažna ali volnena tkanina, prednostno flanela.The technical problem is solved by the invention so that the glove is cut and sewn from a multilayer material, namely a mechanical protective layer consisting of a network of polyolefin or aramid fibers (Kevlar®) on one side of a silicone-bonded insulating layer and / or polyurethane, on the other side of the protective layer, which is intended to be applied directly to the skin and which is a cotton or wool fabric, preferably flannel.

Mehansko zaščitni sloj je preizkušeno bistveno odpornejši na že opisanem preizkusu vreza. Preizkušeno je, da ta sloj zdrži kratkotrajno temperaturno obremenitev do 500° C, s čimer je področje uporabe rokavic razširjeno na varilstvo. Vezno izolativni sloj je potreben zato, da naredi mrežo zaščitnega sloja iz navedenih materialov zadosti kompaktno, da jo je lahko krojiti in šivati, ter istočasno deluje kot zaščitni slojThe mechanical protective layer is tested to be substantially more resistant to the cut test described above. This layer has been tested to withstand a short-term temperature load of up to 500 ° C, extending the scope of the gloves to welding. The bonding layer is necessary to make the mesh of the protective layer compact enough to be cut and sewable and at the same time to act as a protective layer

24394/D14-VIII-94.Vr.24394 / D14-VIII-94.

pred vdorom tekočin v rokavico in kot električni izolator.prior to the ingress of liquids into the glove and as an electrical insulator.

Tretji sloj iz bombažne ali volnene tkanine pa ustvari rokavico prijetno za nošnjo tudi dlje časa, saj je predvidena za profesionalno rabo za ves delovni čas.The third layer of cotton or wool fabric makes the glove comfortable to wear for a long time, as it is intended for professional use all the time.

Po potrebi je med šivanjem rokavice na dlani in dlanski strani prstov lahko na zunanji strani navedenega vsaj troslojnega materiala dodan sloj, ki zagotavlja ustrezno trenje med rokavico in običajnimi materiali, kot so suhe, mokre ali mastne kovine, les, razne umetne snovi, steklo ipd. Prednostno je uporabljeno usnje.If necessary, during the sewing of the glove on the palm of the hand and on the palm of the fingers, a layer can be added on the outside of said at least three-layer material to ensure proper friction between the glove and common materials such as dry, wet or greasy metals, wood, various plastics, glass, etc. . Preferably used leather.

Na hrbtni strani rokavice je po potrebi vstavljen vložek tekstila ali druge perforirane folije, ki poveča dihanje rokavice.A textile or other perforated foil insert is inserted at the back of the glove as needed to increase the glove's breathing.

Na zapestju se rokavica konča z zapestnim trakastim odsekom, ki lahko vsebuje tudi radialno elastični vložek za boljše fiksiraje rokavice na dlani. Prednostno je ta odsek izdelan iz aluminiziranega platna.On the wrist, the glove ends with a wrist strap section, which may also include a radially elastic insert for better fixing of the glove on the palm. Preferably, this section is made of aluminized canvas.

Poliolefinska ali aramidna mreža je v primerjavi z znanimi zaščitnimi sredstvi, ki se uporabljajo v ta namen, izrazito bolj gibka, da bistveno ne ovira prijema in za upogib ne potrebuje velike sile roke. Razen tega posamezna vlakna ne pokajo pri pregibanju v rokavici. Zato je izključena možnost poškodbe z vlakni, ki bi prebodli ostale usnjene in tekstilne plasti rokavice. Razen tega so korozijsko in kemijsko odporna. Usnena zunanja plast je že preizkušena pri znanih tovrstnih rokavicah in ne kaže posebnih pomanjkljivosti.The polyolefin or aramid net is significantly more flexible than the known protective agents used for this purpose, so that it does not significantly impede the grip and does not require a great deal of arm force to bend. In addition, individual fibers do not crack when folded in the glove. Therefore, the possibility of damage to the fibers that would pierce the other leather and textile layers of the glove is excluded. They are also corrosion and chemical resistant. The leather outer layer has already been tested with known gloves of this type and shows no special disadvantages.

Zato je življenska doba rokavice po izumu dolga.Therefore, the glove life of the invention is long.

Razume se, da so rokavice lahko izdelane tudi iz drugih dodatnih slojev na osnovnem opisanem večslojnem materialu glede na posamične dodatne potrebe.It is understood that the gloves may also be made of other additional layers on the basic multilayer material described, depending on the individual additional needs.
