Description
i 146559and 146559
Opfindelsen angår en svømmedykkerdragt, som er fremstillet af et vand- og gastæt, varmeisolerende og elastisk materiale indeholdende gasfyldte, lukkede celler, og som har mindst en ved hjælp af en vandtæt lynlås eller lignende lukkers organ aflukkelig åbning, hvorigennem en dykker kan stige ind og ud af dragten, og hvor dragten neden for halsregionen er forsynet med dels en manuelt eller automatisk aktiverbar ventil til regulering af tilførsel af trykluft til dragtens indre, dels en manuelt aktiverbar ventil til regu-10 lering af luftafgangen fra dragtens indre.-The invention relates to a swimsuit suit which is made of a water and gas tight, heat insulating and elastic material containing gas-filled, closed cells, and which has at least one opening which can be closed by means of a waterproof zipper or similar shutter, through which a diver can enter and out of the suit, and wherein the suit below the neck region is provided with partly a manually or automatically activatable valve for regulating the supply of compressed air to the interior of the suit, partly a manually activatable valve for regulating the air outlet from the suit's interior.-
Fra beskrivelsen til fransk patent nr. 1.426.022 kendes en svømmedykkerdragt, som er fremstillet af et vand- og gastæt, varmeisolerende og elastisk materiale indeholdende et antal indbyrdes forbundne aflange gasfyldte, kanaler.From the description of French Patent No. 1,426,022 a diving suit is known, which is made of a water and gas tight, heat-insulating and elastic material containing a number of interconnected elongated gas-filled channels.
15 Dragten er nedenfor halsregionen forsynet med en ventil til regulering af trykluft til disse kanaler. Dragten er af den såkaldte våde type, hvor dragtmaterialet under dykning, grundet vandets tryk, presses ind til tæt anlæg mod dykkerens krop. Under dykning med denne dragt kan der ikke 20 opretholdes noget stabilt tyndt luftlag mellem,dykkerens, krop og dragtmaterialet, hvorfor der ikke kan opretholdes samme varmeisolation. Der er desuden risiko for at luften i kanalerne vil samle sig i den til enhver tid øverste del af dragten under dykkerens svømning, især fordi tykkelsen 25 af dragtmaterialets ydre væglag, som ligger op til de yd-erst liggende kanaler, er meget lille.15 The suit is below the neck region provided with a valve for regulating compressed air to these ducts. The suit is of the so-called wet type, where the suit material during diving, due to the pressure of the water, is pressed into a close abutment against the diver's body. During diving with this suit, no stable thin layer of air can be maintained between the diver's, body and the suit material, so the same thermal insulation cannot be maintained. There is also a risk that the air in the channels will accumulate in the upper part of the suit at any time during the diver's swimming, especially because the thickness 25 of the outer wall layer of the suit material, which is adjacent to the outermost channels, is very small.
Svømmedragten ifølge opfindelsen er ejendommelig ved, at den er figursyet af et materiale med sådanne elastiske 30 egenskaber og på en sådan måde, at der mellem dragten og dykkerens krop, uanset dykkerens stilling, kan opretholdes et i hovedsagen stabilt tyndt luftlag, og at luftlagets tykkelse kan ændres til regulering af dykkerens opdrift.The swimsuit according to the invention is characterized in that it is shaped from a material with such elastic properties and in such a way that between the suit and the diver's body, regardless of the diver's position, a substantially stable thin air layer can be maintained and that the thickness of the air layer can be changed to regulate the diver's buoyancy.
2 1465592 146559
En opretholdelseaf et sådant tyndt luftlag medfører, at dykkeren, uanset hvilken vanddybde han opererer på, kan opretholde samme varmeisolering i dragten og samme opdrift under bibeholdelse af dykkerens mulighed for at ændre sin 5 opdrift til brug ved hurtig opstigning eller nedstigning.Maintaining such a thin layer of air means that the diver, regardless of the water depth at which he operates, can maintain the same thermal insulation in the suit and the same buoyancy while maintaining the diver's ability to change his 5 buoyancy for use in rapid ascent or descent.
Der opnås tillige, at luftens tilbøjelighed til at samle sig i dragtens dele, uanset hvilken stilling i vandet dykkeren indtager, undgås, idet indre trækkræfter i dragtens materiale bevirker, at dens figur ikke ændres væsentligt 10 med dykkerens stilling i vandet.It is also achieved that the tendency of the air to accumulate in the parts of the suit, regardless of which position in the water occupies the diver, is avoided, as internal tensile forces in the material of the suit cause its figure not to change significantly with the diver's position in the water.
I en svømmedragt, hvor det elastiske materiale indeholdende gasfyldte, lukkede celler er gummi med belægning, kan ifølge opfindelsen belægningen hestå af væv af polyamid.In a swimsuit where the elastic material containing gas-filled, closed cells is rubber with coating, according to the invention the coating can be made of polyamide fabric.
Dette materiales egenskaber sikrer, at der kan opretholdes 15 en sådan passende forskel mellem vandtryk uden for dragten og lufttryk i dragten, at tendens til, at luftmængden samler sig i øverste del af dragten, undgås.The properties of this material ensure that such a suitable difference between water pressure outside the suit and air pressure in the suit can be maintained that the tendency for the amount of air to accumulate in the upper part of the suit is avoided.
Opfindelsen forklares nedenfor under henvisning til tegningen, hvor 20 fig. 1 viser en udførelsesform for en dykkerdragt ifølge opfindelsen, set fra siden, idet en dykker har iført sig dragten og har taget ansigtsmaske på, fig. 2 samme, idet dykkerdragten er vist delvis opsnittet efter et lodret plan, og dykkeren er forsynet med en cyklop, 25 fig- 3 samme set forfra inden brugen og i lille målforhold, fig. 4 et lodret snit gennem dykkerdragtens halsparti i stort målforhold, fig. 5 en samling mellem to materialestykker i dragten, 3 146559 set i tværsnit og i stort målforhold, fig. 6 en handske hørende til dykkerdragten, set i tværsnit» handsken er trukket op over dragtens ene ærme.The invention is explained below with reference to the drawing, in which fig. Fig. 1 shows an embodiment of a diving suit according to the invention, seen from the side, a diver wearing the suit and wearing a face mask, Fig. 2 is the same, the diving suit being shown partly sectioned according to a vertical plane, and the diver is provided with a cyclop, Fig. 3 is the same seen from the front before use and in small dimensions, fig. Fig. 4 is a vertical section through the neck portion of the diving suit in a large dimensional ratio; Fig. 5 shows a joint between two pieces of material in the suit, seen in cross section and in large scale, fig. 6 a glove belonging to the diving suit, seen in cross section »the glove is pulled up over one sleeve of the suit.
Den i figurerene viste dykkerdragt er fremstillet af et 5 vand- og gastæt, varmeisolerende og elastisk materiale indeholdende gasfyldte lukkede celler. Nærmere bestemt består dragten af et antal tilskårne materialestykker 1, 2, jf. fig. 5, der hvert består af et ca. 6,5 mm tykt lag 3 af cél-r lulært gummi med lukkede celler. Dette gummilag 3 kan f.eks.The diving suit shown in the figures is made of a water and gas tight, heat-insulating and elastic material containing gas-filled closed cells. More specifically, the suit consists of a number of cut pieces of material 1, 2, cf. fig. 5, each consisting of an approx. 6.5 mm thick layer 3 of cellular rubber with closed cells. This rubber layer 3 can e.g.
10 være af såkaldt "neopren", som på overfor hinanden liggende sider er forsynet med en belægning af polyamidvæv 4 og 5. Materialestykkerne 1 og 2 ligger op til og er forbundet med hinanden ved hjælp af en samling 6 indeholdende lim eller klæbestof. Vævdelene 4 og 5 er forbundet med hinanden 15 ved hjælp af sømme 7 og 8. Ved at bruge polyamidvæv til belægningerne 4 og 5 opnås foruden forbedret varmeisolation og god beskyttelse af gummilaget 3, at kraftpåvirkningerne på samlingerne 6 reduceres. Hertil kommer, at dragten får den ønskede stabilitet, uanset dykkerens stilling, fordi 20 der kan opretholdes en sådan passende forskel mellem vandtryk uden for dragten og lufttryk i dragten, at tendens til at luftmængden samler sig i øverste de af dragten undgås.10 may be of so-called "neoprene", which on opposite sides is provided with a coating of polyamide fabrics 4 and 5. The material pieces 1 and 2 lie next to and are connected to each other by means of a joint 6 containing glue or adhesive. The fabric parts 4 and 5 are connected to each other 15 by means of seams 7 and 8. By using polyamide fabric for the coatings 4 and 5, in addition to improved thermal insulation and good protection of the rubber layer 3, the force effects on the joints 6 are reduced. In addition, the suit obtains the desired stability, regardless of the diver's position, because such a suitable difference between water pressure outside the suit and air pressure in the suit can be maintained that the tendency for the air volume to accumulate in the upper ones of the suit is avoided.
I fig. 3 er vist, hvorledes der i dragtens midterparti 11 et parti 9 mellem dragtens ben 10 og i et rygparti 12 er 25 tilvejebragt en åbning, hvorigennem dykkeren kan stige ind i og ud af dragten. Denne åbning kan lukkes ved hjælp af en vandtæt lynlås 13. Dragten har desuden foddele 14, som er forsynet med forstærkende gummisåler 15. Dragtens ben og arme 16 er forsynet med forstærkninger 17 henholds-30 vis 18. Til dragten hører også et par handsker 26, se fig.In FIG. 3 shows how in the middle portion 11 of the suit a portion 9 between the legs 10 of the suit and in a back portion 12 an opening is provided through which the diver can ascend into and out of the suit. This opening can be closed by means of a waterproof zipper 13. The suit also has foot parts 14 which are provided with reinforcing rubber soles 15. The legs and arms 16 of the suit are provided with reinforcements 17 and 18 respectively 18. The suit also includes a pair of gloves 26 , see fig.
6, hvis håndledsdel 27 på tætnende måde kan trækkes ind over ærmet 16's linning 28.6, the wrist portion 27 of which can be retracted over the waistband 28 of the sleeve 16 in a sealing manner.

Som vist i fig. 1 er dykkerdragten figursyet, og som vist i fig. 2 kan der uanset dykkerens stilling opretholdes et i hovedsagen stabilt tyndt luftlag 42 mellem dragten og dykkerens krop 22, se nederste del af fig. 2. Dette luft-5 lags tykkelse kan ændres med henblik på regulering af dykkerens opdrift.As shown in FIG. 1, the diving suit is tailored, and as shown in fig. 2, regardless of the diver's position, a substantially stable thin layer of air 42 can be maintained between the suit and the diver's body 22, see lower part of fig. 2. The thickness of this air-5 layer can be changed in order to regulate the buoyancy of the diver.
I fig.· 2 og 4 ses, hvorledes luften i det tynde luftlag hindres i at trænge op i en til dragten hørende hætte 20.Figures 2 and 4 show how the air in the thin air layer is prevented from penetrating into a hood 20 belonging to the suit.
- Nedenfor hætten 20, som fortil er forsynet med en åbning 21 '10 for dykkeren 22's ansigt, er der på et halsparti 19's inderside anbragt en nedad og indad ragende krave 23 af gummi eller andet elastisk materiale, og denne krave har en nedre kant 24, som med et let tryk ligger an mod dykkeren 22rs hals 25. Herved hindres luft i at trænge fra 15 dragtens kropsdel op i hætten 20. Luft, som måtte søge opad mod hætten 20, havner i en luftlomme 38 og vil da gennem sit eget tryk medvirke til at presse kraven 23 tæt-nende ind mod dykkerens hals 25. Det drejer sig her om ret små tryk, hvorfor de ikke vil genere dykkeren. I dragten 20 kan der eventuelt være anbragt andre læbeagtige tætninger efter samme princip, f.eks. rundt om kroppen eller rundt om ærmerne 16 eller benene 10. I sådanne tilfælde kan luft • · slippes ind mellem dragten og dykkerens krop via lufttilførselsventiler 31, som vil blive omtalt nærmere nedenfor, 25 og som er anbragt på disse dragtdele, eller også kan en vis luftstrømning tilvejebringes mellem de forskellige hulrum i dragten ved hjælp af særligt udformede luftkanaler.Below the cap 20, which is provided at the front with an opening 21 '10 for the face of the diver 22, a downwardly and inwardly projecting collar 23 of rubber or other elastic material is arranged on the inside of a neck portion 19, and this collar has a lower edge 24. , which with a light pressure rests against the diver 22rs neck 25. This prevents air from penetrating from the body part of the suit up into the hood 20. Air, which may seek upwards towards the hood 20, ends up in an air pocket 38 and will then through its own pressures help to press the collar 23 tightly against the diver's neck 25. These are rather small pressures, which is why they will not bother the diver. In the suit 20, other lip-like seals may optionally be arranged according to the same principle, e.g. around the body or around the sleeves 16 or the legs 10. In such cases air can be let in between the suit and the diver's body via air supply valves 31, which will be discussed in more detail below, 25 and which are placed on these parts of the suit, or some air flow is provided between the various cavities in the suit by means of specially designed air ducts.
Det er vigtigt, at dykkeren ikke tvinges til at anvende en fast ansigtsmaske 34, se fig. 1, eller en cyklop 35, 30 se fig. 2, for at hindre luft i at strømme ud gennem hættens åbning 21, og at dragten kan anvendes sammen med almindelig standardudrustning.It is important that the diver is not forced to use a fixed face mask 34, see fig. 1, or a cyclop 35, 30 see fig. 2, to prevent air from flowing out through the cap opening 21, and that the suit can be used with standard equipment.
Som vist i fig. 1 og 2 er der i dragtens brystparti 29 5 146559 anbragt en lufttilførselsventil 31, som via en slange er tilsluttet en rørformet trykluftbeholder 30, som dykkeren bærer på ryggen. På brystpartiet 29 findes desuden en luftafgangsventil 33, som let kan betjenes manuelt ved hjælp 5 af en trykknap 32. Herved kan dykkeren let styre det tynde luftlag 42. Sammen med dragten kan dykkeren bære enten en ansigtsmaske 34, se fig. 1, som via en slange er sluttet til trykluftbeholderen 30, og som helt dækker hættens åbning 21, eller dykkeren kan bære en cyklop 35, som er 10 bragt til direkte anlæg mod ansigtshuden ud for hætteåbningen 21, samt et bidemundstykke 36, se fig. 2, som er sluttet til trykluftbeholderen 30. Som antydet med stiplet linie i fig. 4 kan der i dragten være indbygget en opad og indad ragende ekstra krave 37, der aftætner mod overtryk 15 i hætten 20.As shown in FIG. 1 and 2, an air supply valve 31 is arranged in the chest portion 29 5 146559 of the suit, which is connected via a hose to a tubular compressed air container 30, which the diver carries on his back. On the chest portion 29 there is also an air outlet valve 33, which can be easily operated manually by means of a push button 32. Hereby the diver can easily control the thin air layer 42. Together with the suit the diver can wear either a face mask 34, see fig. 1, which is connected via a hose to the compressed air container 30, and which completely covers the opening 21 of the cap, or the diver can carry a cyclop 35, which is brought into direct abutment against the facial skin next to the cap opening 21, as well as a bite nozzle 36, see fig. 2, which is connected to the compressed air container 30. As indicated by the dashed line in fig. 4, an upwardly and inwardly projecting extra collar 37 can be built into the suit, which seals against overpressure 15 in the cap 20.
Når dykkeren skal iføre sig dragten, trækker han først kraven 23 og hætten 20 over sit hoved. Derefter fører han en efter en sine fødder ind gennem dragtens ben 10, hvorefter dragten lukkes med lynlåsen.When the diver is to wear the suit, he first pulls the collar 23 and the cap 20 over his head. Then, one by one, he leads his feet in through the suit's legs 10, after which the suit closes with the zipper.
20 Under dykning kan der som før nævnt tilføres luft til dragten fra dykkerens normale tzykluftbeholder 30 eller den kan tilføres fra en mindre ikke vist hjælpébeholder, således at et tyndt luftlag 42 mellem dragt og dykker opretholdes. Ved at dragten er figursyet, dvs. har god pasform, og er passende fleksibel og 25 stærk, har man opnået, at der ikke kræves store luftmængder i dragtens indre, og at den tilførte luftmængde bliver i dragten, så længe dykkeren selv ønsker det. Dykkeren kan let og bekvemt indtage en hvilken som helst stilling i vandet, uden risiko for at store luftmængder pludselig 30 flytter sig og dermed på uheldig måde påvirker hans opdrift og dermed hans balance. Som følge af det tynde luftlag er de ubehagelige virkninger fra dragten på dykkerens krop hidrørende fra vandtrykket fjernet, og dragten yderDuring diving, as mentioned before, air can be supplied to the suit from the diver's normal double air tank 30 or it can be supplied from a smaller auxiliary tank (not shown), so that a thin layer of air 42 between the suit and the diver is maintained. By the fact that the suit is tailored, ie. has a good fit, and is suitably flexible and strong, it has been achieved that no large amounts of air are required in the interior of the suit, and that the supplied amount of air remains in the suit as long as the diver himself wishes. The diver can easily and conveniently occupy any position in the water, without the risk of large amounts of air suddenly moving and thus adversely affecting his buoyancy and thus his balance. Due to the thin layer of air, the unpleasant effects of the suit on the diver's body resulting from the water pressure are removed, and the suit provides
