Uppfinnare: K S R Hultgren Foreliggande uppfinning avser en anordning vid lucka, sarskilt lucka for en instigningsOppning i en farbar kanon och liknande. Inventor: K S R Hultgren The present invention relates to a device at a hatch, in particular a hatch for an entry opening in a navigable cannon and the like.

Luckor for in- och utstigningsoppningar vid farbara kanoner och liknande har med hansyn till att de skall bilda erforderligt skydd for i det av luckan slutna rummet befintlig servis mycket stor tyngd, varfor en dylik lucka ofta blir svarmanovrerbar. I all synnerhet om luckan, som ibland är onskvart, skall vara anordnad i en vasentligen horisontell vagg kan det vid kanda sat att hanga luckor vara erforderligt att anordna sarskilda spel fOr att fora Indian frail stangt till oppet lage och vice versa. Doors for entry and exit openings at navigable guns and the like have, with regard to the fact that they should form the necessary protection for the tableware present in the room closed by the door, a very large weight, for which reason such a door often becomes maneuverable. In particular, if the door, which is sometimes unsightly, is to be arranged in a substantially horizontal cradle, it may be necessary in the case of hanging doors to arrange special games in order to line Indian frail rods to open law and vice versa.

Foreliggande uppf inning avser en anordning for hangning av en med en oppning, exempelvis in- och utstigningsoppning, samverkande lucka, med vilken anordning Oppnandet och stangandet av luckan underlattas av sâ anordnade organ, att luckan vid dess fOrande fran stangt till oppet lge och vice versa av organen utsatts for krafter, som i vasentlig grad motverkar en av luckans tyngd orsakad kraft, som stravar att f6ra luckan ur ett intaget lase, och med vilken luckan fir forbar till och frau stangt respektive oppet lage under en rOrelse vasentligen parallellt med den vagg i vilken oppningen Or anordnad. The present invention relates to a device for hanging a door cooperating with an opening, for example an entry and exit opening, with which device the opening and closing of the door is facilitated by such arranged means that the door at its leading from the bar to the open position and vice versa by the members subjected to forces which substantially counteract a force caused by the weight of the hatch, which strains to move the hatch out of an engaged lase, and with which the hatch is moved to and from the rod and open, respectively, during a movement substantially parallel to the cradle in which opening Or arranged.

For detta andamal Or luckan fast vid vaggen under formedling av tva, vardera minst tva svangarmar innefattande parallellstangssystem, vilka Or anordnade pa var sin sida cm Indian svangbara I med varandra parallella plan, varvid varje svangarm vid den anden an fast med en i namnda plan svangbar led i vaggen och vid den andra vid en samma plan svangbar led i luckan och en eller flera i lager i luckan lagrade, mot am-Ida svangnings plan vinkelrata ledtappar Or vridfast forbund; na med var sin torsionsstang, vars andra On-de Or vridfast fast i luckan. For this purpose, the door is fixed to the cradle while forming two, each at least two pivot arms comprising parallel rod systems, which Or are arranged on each side cm Indian pivotable in parallel planes, each pivot arm at the other fixed with a pivotable in said plane. joint in the cradle and at the other at a same plane pivotable joint in the door and one or more bearings in bearings in the door stored, perpendicular to the am-Ida pivot plane Or pivotally connected; each with its own torsion bar, the other On-de Or rotatingly fixed in the door.

Luckan Or foretradesvis hangd i fyra lankstanger som bildar tvã parallellstangssystem, i vilka varje svangarm vid sin i luckan ledande ande pa angivet salt vid en vridtapp ar fast vid sin ena ande vid en torsionsstang, vars andra ande Or ovridbart fast vid luckan. The door Or is preferably hung in four long bars which form two parallel bar systems, in which each pivot arm at its leading spirit in the door on specified salt at a pivot pin is fixed at one end at a torsion bar, the other end of which is inextricably attached to the door.

Denim anordning for svangning av luckan till respektive frau oppet respektive stangt lage mojliggor dessutom att lasorgan for fast-banning av luckan i endera ay dessa bada IA-gem eller i mellanliggande, eventuellt onskade lagen, kan vara anordnade helt pA luckan, varfor en vagg, i vilken hickan Or anordnad, inte behaver vara utrustad med speciella lAsorgan. For detta andamal Or atminstone en svangarm men lampligen en svangarm i varje parallellstangsystem utrustad med ovridbart I fOrhallande med svangarmen forbundna an-slag semi pa luckan anordnade, med dessa an-slag samverkande sparrorgan, som Or forbara till och fran ingrepp med de pa lankstangerna anordnade anslagen. Denim devices for pivoting the door to the respective open and closed bar make it possible, moreover, that locking means for fastening the door in either these baths or in the intermediate, possibly desired layers, can be arranged completely on the door, for which reason a cradle, in which the hiccup Or is arranged, does not need to be equipped with special lAs organs. For this purpose, there is at least one pivot arm but suitably a pivot arm in each parallel rod system equipped with non-rotatable abutments connected to the pivot arm semi-arranged on the door, with these abutments cooperating locking means which estimates.

Uppfinningen beskrivs narmare i anslutning till pa bifogad ritning visade figurer, av vilka fig. 1 schematiskt visar en lucka enligt uppfinningen i ett mot den vagg i vilken Oppningen Or anordnad infant lage, fig. 2 visar luckan under uppfallning fran detta lage, fig. 3 visar utforandet av sparrorgan fOr luckan mer i detalj samt fig. 4 och fig. illustrerar lasningen av luckan i olika lagen. The invention is described in more detail in connection with the figures shown in the accompanying drawing, of which Fig. 1 schematically shows a door according to the invention in an infant layer arranged against the cradle in which the opening Or is arranged, Fig. 2 shows the door during striking from this layer, Fig. 3 shows the design of the ratchet means for the door in more detail and Fig. 4 and Fig. illustrate the welding of the door in different layers.

I en vagg 1 Or en oppning 2 anordnad, som skall vara tillslutbar med en lucka. Vid det i figuren illustrerade utforingsexemplet pa en anordning enligt uppfirmingen bestar Indian av en platta 3, som i slutet lage kan tacka oppningen 2, som framgar ay fig. 1. Luekan 2 ar fast vid vaggen 1 under formedling av fyra svangarmar 4, 4' och 5, 5', som vardera vid ena anden ar fast vid vaggen 1 med en led 6, 6' resp. 7, 7' och vid luckan med en led 8, 8' resp. 9, 9', varvid svangarmarna 4 och 5 it ena sidan och 4' och 5' a andra sidan in-hordes bildar ett parallellstangsystem, sa att luckan vid ut- och insvangning i forhallande till vaggen kommer att f en vasentligen translatorisk rorelse under svangarmarnas svangning. Det Or klart att svangarmarna 4 och 5 respektive 4' och 5' i varje parallellstangsystem jute behover vara exakt lika langa, utan att de kan utforas med nagot olika langd om del av nagot skill Or Onskvart att vinkeln mellan vaggplanet och luckans plan skall andras under luckans svangning frail det lage dar den ansluter till vaggen kring oppningen. In a cradle 1 Or an opening 2 is provided, which must be closable with a hatch. In the exemplary embodiment of a device according to the invention illustrated in the figure, Indian consists of a plate 3, which at the end can thank the opening 2, which is shown in Fig. 1. The hatch 2 is fixed to the cradle 1 while forming four swing arms 4, 4 '. and 5, 5 ', each of which at one end is fixed to the cradle 1 with a joint 6, 6' respectively. 7, 7 'and at the door with a joint 8, 8' resp. 9, 9 ', whereby the swing arms 4 and 5 on one side and 4' and 5 'on the other side are formed form a parallel rod system, so that the door when swinging out and swinging in relation to the cradle will have a substantially translational movement under the swing arms. oscillation. It is clear that the swing arms 4 and 5 and 4 'and 5', respectively, in each parallel bar system jute need to be exactly the same length, without being able to be made with a slightly different length if part of any difference. the swing of the door frail the layer where it connects to the cradle around the opening.

I det visade utforandet Or de i luckan lag-fade andarna av samtliga svangarmar fast torbundna med ena anden av en torsionsstang 10, 10', 11 respektive 11', vars ena ande kan bilda lagertappen for tillhkande svangarm eller vara ovridbart fast vid en i respektive lager 8, 8', 9, 9' vridbar, vid tillhorande svang'arm fast axeltapp. Varje torsionsstang Or fast luckan, i det visade utforandet genom att med hommar 15 vara inford i med motsvaran- deforsedda hM 16 i klackar 17 pa luckan, som samtidigt lampligen bildar lager.ytor i lederna 8, 8', 9 respektive 9'. In the embodiment shown, the spirits fixed in the hatch of all swing arms are fixedly bonded to one end of a torsion bar 10, 10 ', 11 and 11', respectively, one end of which may form the bearing pin for adjacent swing arm or be rotatably fixed to a respective bearings 8, 8 ', 9, 9' rotatable, at the associated pivot arm fixed shaft journal. Each torsion bar fixes the door, in the embodiment shown by inserting with homs 15 in correspondingly provided hM 16 in lugs 17 on the door, which at the same time suitably form bearing surfaces in the joints 8, 8 ', 9 and 9', respectively.

Med en pa detta satt med parallellstangsystem svangbar lucka kart man vicl lamplig dimensionering av torsionsstangerna uppnit att tyngden av en vasentligen horisontell lucha under hela svangningen fran stangt lage till oppet i vasentlig grad motverkas av en kraft vid svangarmsandarna, som orsakas av torsionsmoment i torsionsstangerna. Om man forutsatter att torsionsstangerna ar sit anordnade att de hate utsatts for en vridande kraft nar svangarmarna ligger vasentligen vertikalt uppat fran vaggen 1 kommer tyngdkraftens moment kring lederna 6, 6', 7, 7' att motverkas av torsionsmomentet pa torsionsstangerna, varigenona den fdr fOliniug av luckan itt endera hMlet erforderliga kraften i -vasentlig gad kan kompenseras vid lamplig dimensionering av torsionsstangerna. Visserligen varie,rar tyngdkraftens moment kring lederna i vaggen 1 fran det lage i vilket stangerna lig(rer vertikalt som sinus far vinkeln mellan svangarmarna och vertikalen, medan torsionskraften Or vasentligen proportionell mot sam- mamen vid lampligt val av fjader- konstant blir den for svangning av luckan erforderliga kraften far att astadkomma for svangning av luckan mellan slutet lage vid 15ppningen .eller oppet lage, exempelvis n.ed- falld mot vaggen vid sidan av oppningen i vaggen erforderligt med- eller motverkande tillaggsmoment obetydlig i forhallande till luckans tyngd. With a door which can be pivoted with a parallel rod system, a suitable dimensioning of the torsion bars is provided so that the weight of a substantially horizontal hatch during the entire swing from bar to the top is substantially counteracted by a force at the swing arm sands caused by torsional torque in the torsion bars. Assuming that the torsion bars are arranged so that they have been subjected to a rotating force when the swing arms are substantially vertically upwards from the cradle 1, the moment of gravity around the joints 6, 6 ', 7, 7' will be counteracted by the torque on the torsion bars, whereby the former of the door itt either hMlet required force in -significant gad can be compensated by appropriate dimensioning of the torsion bars. Admittedly, the moment of gravity around the joints in the cradle 1 varies from the position in which the rods lie vertically as a sine wave at an angle between the swing arms and the vertical, while the torsional force the force required by the door to effect the pivoting of the door between the end of the door at the opening or the open door, for example falling down towards the cradle next to the opening in the cradle, requires additional or counteracting additional action insignificant in relation to the weight of the door.

Langden hos svangarmarna, sarskilt hos svangarmarna 5 och 5', Or givetvis sa vald, att Oppningen 2 kan hen frilaggas vid utsvangningen av luckan, vilket innebar att lankstangerna 5 och 5' skall vara minst half-ten sit langa som Indians langd i svangningsriktningen. Om vaggen pa den sida out luckan, mot vilken denna falls upp, ligger i yinkel mot vaggen vid oppningen och luckan aven I. uppf alit ldge skall ligga intill vaggen, kan, som tidigare namnts, svangarmarna 4, 4' ha en annan langd On svangarmarna 5, 5'. The length of the swing arms, especially of the swing arms 5 and 5 ', Or of course so chosen, that the opening 2 can be exposed when the door is swung out, which meant that the length bars 5 and 5' must be at least half as long as the length of the Indian in the direction of swing. If the cradle on the side out the door, against which it falls up, is at an angle to the cradle at the opening and the door also I. the upper ldge is to lie next to the cradle, as previously mentioned, the swing arms 4, 4 'can have a different length On arches 5, 5 '.

Uppfinningen avser ocksa organ f Or lasning av luckan lampligen i ett antal olika lagen. FOr detta andamal Or i det visade utforandet lankstangerna 5 och 5' utrustade med anslag, vilka i det visade utforandet bildas av hit! 20 och 21 respektive 20' och 21' i skivor 22 respektive 22', som Or ovridbart fasta vid den i luckan 3 lagrade anden av var sin lankstang 5 respektive 5'. Haien 20, 20' respektive 21, 21' Or anordnade for samverkan med sparrorgan, som Or forbara mot och fran skivan i gejder i Indian och som har visas i form av alternativt i beroende av luckans rage i halen 20, 21 respektive 20', 21' inforbara kolvar 23 respektive 23', som Or paverkbara via stanger 24, 24', kopplade till ett lasvred 25. The invention also relates to means for welding the door suitably in a number of different layers. For this purpose, in the embodiment shown the longitudinal rods 5 and 5 'are equipped with stops, which in the embodiment shown are formed by hit! 20 and 21 and 20 'and 21', respectively, in discs 22 and 22 ', respectively, which Or is inextricably attached to the spirit of the longitudinal rod 5 and 5', respectively, stored in the door 3. The sharks 20, 20 'and 21, 21', respectively, are arranged for co-operation with chisel means, which Or carry towards and from the disc in guides in Indian and which have been shown in the form of alternatively depending on the rage of the hatch in the tail 20, 21 and 20 ', respectively. 21 'insertable pistons 23 and 23', respectively, which can be actuated via rods 24, 24 ', coupled to a welding knob 25.
