Suojalaiteprotector

KeksinnOn kohteena on suojalaite, etenkin hitsaus-suojus, joka kasittaa paan varaan sovitettavan, kayttajaa 5 sateilylta ja kipinOilta suojaavan, lapinakymattttmasta materiaalista valmistetun osan, joka on varustettu kaytta-jan silmien kohdalla olevalla lapinakyvaiia alueella ja jossa suojalaitteessa kayttajan silmien kohdalle on lisaksi sovitettu yldis kaannettava suojalasi.The invention relates to a protective device, in particular a welding shield, which provides a head-mounted, non-shielded part for protecting the user from rain and sparks, which is provided in the area of the shoulder strap at the wearer's eyes and in which the shield is protective glass.

10 Tailaiset suojalaitteet ovat nykyaan hyvin tunnettu- ja etenkin hitsaustOiden yhteydesta. Tavanomaisin rakenne muodostuu esimerkiksi puuta, metallia, muovia jne. olevasta kopasta, joka sovitetaan tydntekijan paan varaan niin, etta se suojaa tyOntekijan kasvot. Em. koppaan on lisaksi tehty 15 aukko kayttajan silmien kohdalle ja aukon kohdalle on sovitettu suojalasi, jonka lapi itse hitsauskohtaa voidaan tarkastella hitsauksen aikana. Kayttajan silmien kohdalle tehtyyn aukkoon on joissakin tapauksissa sovitettu lapina-kyva levy, joka sulkee aukon mutta jonka lapi kayttaja 20 Pystyy nakemaan. Lapinakyva levy voi olla esimerkiksi 13pi-nakyvaa muovimaterialia. Suojalasi on sovitettu paikalleen niin, etta se voidaan kaantaa asentoon, jossa se peittaa aukon ja vastaavasti asentoon, jossa se on sivuun kaannet-tyna niin, etta suojalaitteen kayttaja nakee aukon lapi 25 ymparilleen. Suojalasi on valmistettu sellaisesta materiaalista, etta sen lapi voidaan tarkastella hitsauskohdetta hitsauksen aikana.10 Such protective devices are now well known, especially in connection with welding. The most conventional structure consists, for example, of a hood of wood, metal, plastic, etc., which is fitted to the head of the worker so as to protect the worker's face. Em. the hood is additionally provided with 15 openings at the user's eyes and a protective glass is arranged at the opening, through which the welding point itself can be viewed during welding. In some cases, a lap-like plate is fitted in the opening made at the user's eyes, which closes the opening but which the user 20 can see. The lapin-visible plate can be, for example, a 13pi-visible plastic material. The protective glass is arranged in such a way that it can be turned to a position in which it covers the opening and, respectively, to a position in which it is folded aside so that the user of the protective device wraps the opening 25 around it. The protective glass is made of such a material that its blade can be viewed during welding.

Aiemmin tunnettujen ratkaisujen huonona puolena on .. . ollut se, etta suojalaitteen kayttajan nakttkyky ymparilleen • 30 on ollut rajoitettu ja hankalasti aikaansaatavissa. Tahan on ollut syyna se, etta kayttaja ei nae ymparilleen tai edes hitsauskohdetta mikaii suojalasi on kopan lapinakyvan alueen peittavassa asennossa ja mikaii hitsaustyO ei ole kaynnissa. Kayttajan, ts. hitsaustyOta suorittavan henkildin 35 on aina ennen hitsaustyOn aloittamista ja myOs hitsauksen 2 90624 keskeytyesså kåånnettåvå joko suojalasi tai koko suojalaite pois silmienså edestå ennenkuin han pystyy nåkemåån hit-sauskohteen ja esimerkiksi asettamaan puikon oikeaan koh-taan. Ennen hitsauksen aloittamista suojalasi tai koko kop-5 pa on luonnollisesti kåånnettåvå takaisin kasvoja ja silmiå suojaavaan asentoon. Em. toiminta on hankalaa ja vaatii kaytannossa ainakin yhden kåden kåyttoå. Nåkokenttåå rajaa vielå se, ettå koppa on tehtåvå sellaiseksi, ettå hitsauk-sessa syntyvå såteily ei pååse mitåån kautta hitsaajan sil-10 miin. Nåin olien hitsaajan nåkokenttå on hyvin huono sil-loin kun suojalasi on kåånnettynå silmien eteen. Kaytannossa hitsaaja ei nåe tålloin muuta kuin hitsattavan kohteen.The disadvantage of previously known solutions is ... has been that the visibility of the protective device user around him has been limited and difficult to achieve. The reason for this has been that the user does not look around or even the welding object mikaii the protective glass is in the position covering the flattened area of the hood and mikaii weldingO is not running. The user, i.e. the person performing the welding operation 35, must always turn either the protective glass or the entire protective device out of front of his eyes before starting the welding operation and when the welding operation is interrupted before he can see the welding object and, for example, place the stick in the right place. Before starting welding, the safety glass or the entire kop-5 pa must, of course, be turned back to the face and eye protection position. Em. operation is cumbersome and requires the use of at least one hand in use. The field of view is further limited by the fact that the hood must be made in such a way that the radiation generated during welding does not enter the welder's eye in any way. This makes the welder's field of vision very poor when the goggles are turned in front of the eyes. In use, the welder then sees nothing but the object to be welded.

Keksinnon tarkoituksena on aikaansaada suojalaite, jonka avulla aiemmin tunnetun tekniikan epåkohdat voidaan 15 eliminoida. Tåhån on pååsty keksinnon mukaisen suojalait-teen avulla, joka on tunnettu siitå, ettå låpinåkyvån alueen alapuolelle on muodostettu sinånså tunnettu låpinå-kyvå tarkkailualue, joka on sinånså tunnetusti olennaisesti samansuuntainen suojalasilla varustetun låpinåkyvån alueen 20 kanssa, jolloin kåyttåjå voi katsoa tyokohdetta tarkkailu-alueen låpi olennaisesti alaspåin silloinkin, kun suojalasi on kåånnettynå kåyttåjån silmien eteen peittåmåån låpinåkyvån alueen ja ettå suojalasin alareunaan on sovitettu suo-jalasin alareunasta olennaisesti alaspåin suuntautuva si-25 nånså tunnettu suojalevy, joka eståå såteilyå pååsemåstå tarkkailualueelle silloin, kun tyokohteeseen katsotaan suojalasin låpi.The object of the invention is to provide a protective device by means of which the disadvantages of the prior art can be eliminated. This is achieved by means of a protective device according to the invention, characterized in that a transparent observation area known per se is formed below the transparent area, which is known to be substantially parallel to the transparent area 20 provided with the protective glass, whereby substantially downwards, even when the protective glass is folded over the transparent area to be covered in front of the wearer's eyes, and that the lower edge of the protective glass is fitted from the lower edge of the safety glass to the

Keksinnon etuna aiemmin tunnettuun tekniikkaan nåh-den on se, ettå suojalaitteen kåyttåjå pystyy tarkastele-30 maan esimerkiksi hitsauskohdetta, vaikka suojalasi on kåånnettynå kåyttåjån silmien eteen. Hitsaaja voi siis esimerkiksi hitsauksen keskeytyesså asettaa puikon uudestaan tarkasti oikeaan kohtaan, vaikka suojalasi on kåånnettynå silmien eteen ja silti suojauskyvystå ei ole tingitty. 35 Keksinnon mukaista suojalaitetta kåytettåesså kåsiå ei 3 90624 tarvitse kayttaa lainkaan em. tilanteissa. KeksinnOn etuna on edelleen sen yksinkertaisuus, jolloin sen kayttOOnotto-kustannukset muodostuvat edullisiksi.An advantage of the invention over the prior art is that the user of the protective device is able to view, for example, the welding object, even if the protective glass is turned in front of the user's eyes. Thus, for example, when welding is interrupted, the welder can reposition the rod in exactly the right place, even if the safety glass is turned in front of the eyes and still the protective ability has not been compromised. When using the protective device according to the invention, it is not necessary to use the hands 3 90624 at all in the above-mentioned situations. A further advantage of the invention is its simplicity, whereby its operating costs become low.

Keksintoa ryhdytaan selvittamaan seuraavassa ohei-• 5 sessa piirustuksessa esitetyn eraan edullisen suoritusmuo- don avulla, jolloin kuvio 1 esittaa keksinnOn mukaista suojalaitetta periaatteellisena sivukuvantona, kuvio 2 esittaa kuvion 1 mukaista suojalaitetta 10 periaatteellisena sivukuvantona tilanteessa, jolloin suoja- lasi on kaannetty ylOs, kuvio 3 esittaa kuvion 1 tilannetta perspektiiviku-vantona ja kuvio 4 esittaa kuvion 2 tilannetta perspektiiviku-15 vantona.The invention will be explained by means of a preferred embodiment of the embodiment shown in the following drawing, in which Fig. 1 shows a protective device according to the invention in a schematic side view, Fig. 2 shows a protective device 10 in Fig. 1 in a schematic side view in a situation where the protective glass is covered. shows the situation of Figure 1 in a perspective view and Figure 4 shows the situation of Figure 2 in a perspective view.

Kuvioissa on viitenumeron 1 avulla merkitty suoja-laitteen kayttajan paan varaan sovitettavaa osaa, joka suojaa kayttajaa sateilylta ja kipinOilta, joita syntyy esimerkiksi hitsaustyOn aikana. Osa 1 on valmistettu lapi-20 nakymattOmastamateriaalista, esimerkiksi muovimateriaalis-ta. Viitenumeron 2 avulla kuvioihin on merkitty kayttajan silmien kohdalla oleva lapinakyva alue. Kuvioiden sovellu-tusmuodossa lapinakyva alue 2 on muodostettu osaan 1 teh-dysta aukosta ja siihen sovitetusta låpinakyvaa materiaalia : : 25 olevasta levyosasta 3. Viitenumeron 4 avulla kuvioihin on merkitty kaannettava suojalasi. Suojalasi 4 on kiinnitetty osaan 1 niin, etta se voidaan kaantaa kayttajan silmien eteen, jolloin se peittaa em. lapinakyvan alueen ja mahdol-... listaa esimerkiksi hitsauskohteen tarkastelemisen hitsaus- 30 tyOn aikana. Tama asento on esitetty kuvioissa 1 ja 3. Suojalasi 4 voidaan kaantaa my5s asentoon, jossa se ei peita lapinakyvaa aluetta 2, jolloin suojalaitteen kayttaja pstyy nakemaan alueen 2 låpi ympåristOdnsa. Tama suojalasin 4 asento on esitetty kuvioissa 2 ja 4. Viitenumeron 5 avul-35 la kuvioihin on merkitty valineet, joiden avulla suojalaite 4 90624 voidaan tukea kayttajan paan varaan. Em. valineet ovat alan ammattimiehelle taysin normaalia tekniikkaa, joten ko. vaiineita ei tSssS yhteydessa kuvata tarkemmin.In the figures, reference numeral 1 denotes a part of the protective device which can be fitted to the user's head and which protects the user from rain and sparks which occur, for example, during welding. Part 1 is made of a lap-20 invisible mat material, for example a plastic material. Reference numeral 2 denotes a patchy area at the user's eyes in the figures. In an embodiment of the figures, the flapable area 2 is formed in the part 1 by an opening made of a plate part 3 and a permeable material fitted therein: 25 by means of reference numeral 4 in the figures. The protective glass 4 is attached to the part 1 so that it can be folded in front of the user's eyes, whereby it covers the above-mentioned patchy area and makes it possible, for example, to examine the welding object during welding. This position is shown in Figures 1 and 3. The protective glass 4 can also be turned to a position where it does not cover the lap-like area 2, whereby the user of the protective device can see through the area 2. This position of the goggle 4 is shown in Figures 2 and 4. In the figures of reference numeral 5 to 35-1a, the means by which the protective device 4 90624 can be supported on the user's head are indicated. Em. the tools are a completely normal technique for a person skilled in the art, so the silences are not described in more detail in the context of tSssS.

Keksinndn olennaisen idean mukaisesti lapinakyvan 5 alueen 2 alapuolelle on muodostettu lapinakyva tarkkailu-alue 6, joka on olennaisesti samansuuntainen em. alueen 2 kanssa. Kayttaja voi katsoa tyOkohdetta tarkkailualueen lapi olennaisesti alaspain silloinkin kun suojalasi 4 on kaannettyna kayttajan silmien eteen peittamaan lapinakyvan 10 alueen 2. Em. tilanne nakyy erityisen selvasti kuviossa 1, jossa kayttajan katseen suunta tarkkailualueen 6 lapi on merkitty periaatteellisesti nuolen KS avulla.According to the essential idea of the invention, a lapable observation area 6 is formed below the area 2 of the lapina image 5, which is substantially parallel to the above-mentioned region 2. The user can view the workpiece substantially down through the observation area, even when the protective glass 4 is folded in front of the user's eyes to cover the area 2 of the patch image. is shown clearly in Figure 1, where the user's gaze direction 6 into the observation area is schematically indicated by means of arrow KS.

Em. termilia "olennaisesti samansuuntainen" tarkoi-tetaan tassS yhteydessa sita, etta tarkkailualueen 6 taso 15 on olennaisesti yhdensuuntainen lapinayvan alueen 2 tason kanssa.Em. the term "substantially parallel" in the context of tassS means that the plane 15 of the monitoring area 6 is substantially parallel to the plane of the lapinayva area 2.

Suojalasin 4 alarunaan on keksinniin mukaisesti sovi-tettu suojalasin alareunasta olennaisesti alaspain suuntau-tuva suojalevy 7. Suojalevyn 7 tarkoituksena on estaa s3-20 teilya paasemasta tarkkailualueelle 6 sillon kun tydkohdet-ta katsotaan lapinakyvan alueen 2 eteen kaannetyn suojalasin 4 lapi.According to the invention, a protective plate 7 extending substantially downwards from the lower edge of the protective glass is arranged on the lower edge of the protective glass 4. The purpose of the protective plate 7 is to prevent s3-20 from escaping from the station to the observation area 6 when the face is viewed in front of the protective glass 4.

Kuvioiden sovellutusesimerkissa lapinakyva tarkkai-lualue 6 on muodostettu kayttajaa kipinOilta ja sateilylta : 25 suojaavaan osaan 1 muodostetusta aukosta ja siihen sovite-tusta lapinakyvaa materiaalia olevasta levysta 8. Levyn 8 materiaali voi olla edullisesti samaa materiaalia kuin levyosan 3 materiaali. Materiaalina voidaan kayttaa esimer-kiksi sopivaa muovimateriaalia.In the exemplary embodiment of the figures, the non-stick monitoring area 6 is formed by an opening formed in the protective part 1 of the user spark and rain: and a sheet 8 of non-transparent material fitted thereto. The material of the plate 8 may preferably be the same material as the material of the part 3. As the material, for example, a suitable plastic material can be used.

; 30 Ideana keksinnOssa on se, ettå suojalaitteen kaytta jan ei tarvitse kaannelia suojalasia tai koko suojalaitetta silloin kun han esimerkiksi haluaa keskeyttaa hitsaustyttn, tarkastella tydkohdetta ja aloittaa hitsauksen uudelleen. Keksinnfin mukaista suojalaitetta kaytettaessa kayttaja 35 pystyy katsesuuntaa muuttamalla tarkastelemaan tyOkohdetta 5 90624 tarkkailualueen ISpi vaikka suojalasi onkin hitsaustyOn edellyttamassa asennossa. Hitsaustilanteessa syntyva hai-tallinen sateily ei kuitenkaan paase hitsattaessa kulkeutu-maan tarkkailualueelle 6 ja siita edelleen suojalaitteen . 5 kayttajan kasvoille, koska suojalasin alareunasta alaspain suuntautuva suojalevy 7 estaa sateilyn kulun tarkkailualueelle. On nimittain huomattava, etta hitsaustilanteessa kohdetta tarkastellaan suojalasin 4 lapi, jolloin suojalevy 7 tulee tyokohteen ja tarkkailualueen 6 vaiiin ja estaa 10 sateilyn paasyn tyOkohteelta tarkkailualueelle. KeksinnOn mukaista suojalaitetta kaytettaessa kasia ei tarvitse kayt-taa esimerkiksi suojalasin kaantelyyn tyOn eri vaiheissa ja suojaustehosta ei kuitenkaan ole tingitty lainkaan. Nainol-len tyOturvallisuus jopa paranee, silia keksinnOn mukaista 15 suojalaitetta kaytettaessa esimerkiksi suojalasi on aiempia ratkaisuja varmemmin oikeassa asennossa jokaisen hitsaus-vaiheen alkaessa, koska sita ei vaiilia tarvitse kaantaa pois silmia suojaavasta asennosta. KeksintOa kaytettaessa kasia voidaan kayttaa yksinomaan hitsausvaiineen ja mahdol-20 lisesti hitsattavien osien tukemiseen ja kannattamiseen, koska esimerkiksi suojalasiin ei tarvitse koskea tyOn vaii-vaiheissa. TyOturvallisuus paranee nainollen taitakin osin.; The idea of the invention is that the user of the protective device does not need a cover glass or the entire protective device when, for example, he wants to interrupt the welding filling, view the workpiece and start welding again. When using the protective device according to the invention, the user 35 is able to view the work area 5 90624 in the monitoring area ISpi by changing the viewing direction, even if the protective glass is in the position required for welding. However, the harmful rain generated in the welding situation does not escape to the monitoring area 6 and further to the protective device during welding. 5 to the face of the user, because the protective plate 7 directed downwards from the lower edge of the goggles prevents the passage of rain to the monitoring area. Namely, it should be noted that in the welding situation, the object is viewed through a goggle 4, whereby the protective plate 7 enters the work area and the monitoring area 6 and prevents rain from passing from the work area to the monitoring area. When using the protective device according to the invention, it is not necessary to use the case, for example, to cover the protective glass at different stages of work, and however, the protective effect has not been compromised at all. The safety of the Nainol even improves, for example when using the protective device 15 according to the invention. When using the invention, the cassette can be used exclusively for supporting and supporting the welding tool and possibly the parts to be welded, because, for example, the goggles do not have to be touched during the work steps. Occupational safety is improving in some respects.

Edelia esitettya sovellutusesimerkkia ei ole tarkoi-tettu mitenkaan rajoittamaan keksintoa, vaan keksintca 25 voidaan muunnella patenttivaatimusten puitteissa taysin vapaasti. Nainollen on selvaa, etta keksinnttn mukaisen suojalaitteen tai sen yksityiskohtien ei valttamatta tarvitse olla juuri sellaisia kuin kuvioissa on esitetty, vaan .. . muunlaisetkin ratkaisut ovat mahdollisia. Suojalaitteen 30 muodon ei tarvitse olla juuri sellainen kuin kuvioissa on esitetty. Eri yksityiskohdat voidaan myOs muotoilla kulloi-senkin tilanteen mukaan. Tarkkailualueen ei valttamatta tarvitse olla lapinakyvan alueen jatkeena kuten kuvioiden esimerkissa, vaan tarkkailualue voidaan myOs muodostaa 35 omasta erillisesta aukosta ja siihen sovitetusta lapinaky- 6 90624 vasta osasta. LMpinSkyvSt levyt voidaan jopa jattaa pols seka tarkkailualueesta etta lapinakyvasta alueesta mikali tailainen ratkaisu katsotaan tarpeelliseksi. Lapinakyva tarkkailualue ja lapinakyva alue voidaan muodostaa myds 5 yhtenaisesta jatkuvasta alueesta, jolloin suojalasi alas-kaannetyssa asennossaan peitta em. yhtenaisen alueen yia-osan, mutta jattaa alaosan avoimeksi. Em. yhtenainen alue voidaan muodostaa esimerkiksi lapinakymattOmaan osaan teh-dysta aukosta, johon tarvittaessa voidaan sovittaa lapina-10 kyva levy. Lapinakyva levy voi olla yhtenainen tai kaksi-osainen jne. Kaksiosaisessa sovellutuksessa lapinakyvat levyt voidaan valmistaa joko samasta materiaalista tai eri materiaalista.The application example presented above is not intended to limit the invention in any way, but the invention 25 can be modified completely freely within the scope of the claims. Thus, it is clear that the protective device according to the invention or its details do not necessarily have to be exactly as shown in the figures, but ... other solutions are possible. The shape of the protective device 30 need not be exactly as shown in the figures. The various details can also be formatted according to the current situation. The observation area does not necessarily have to be an extension of the patch-like area as in the example of the figures, but the observation area can also be formed from 35 separate discrete openings and only a part of the patch-able area 690624 fitted to it. LMpinSvtiv plates can even be left in the poles, both in the observation area and in the lapland area, if a solution is considered necessary. The lapina-observation area and the lapina-area can be formed from a uniform continuous area myds 5, whereby the protective glass in its down-folded position covers the yia part of the above-mentioned uniform area, but leaves the lower part open. Em. a uniform area can be formed, for example, in an opening made in a part of the patchwork to which a patch-10 plate can be fitted, if necessary. The flat sheet can be solid or two-part, etc. In a two-part application, the flat sheets can be made of either the same material or a different material.
