Abstract

A caisson (10) primarily intended for temporary closing of a window opening (36) on the outside of a house when performing repair, washing or other types of window work. The caisson comprises a foldable, closed frame (12) made up of frame pieces (14, 16, 18, 20) that are flexibly connected with each other. The frame is dimensioned in such a way that it can be easily attached against the facade (52) outside of the window opening when extended. The caisson also comprises at least one piece of sheeting (340) or the like that is fixed to and stretches over the frame. An outer rod (42) or the like, positioned to allow engagement against the frame (12), and in inner rod (44) or the like, positioned to allow engagement against the inside of the house, are also part of the caisson (10). A tensioner (46) working between the rods is designed to press the rods towards each other when the caisson is mounted. At that time, the frame is tensioned and held in position against the facade.<IMAGE>

Description

15 20 25 30 35 8200785-7 dylikt arrangemang kräver emellertid stora insatser både personellt och materiellt. Dessutom utgör de uppspända plast- folierna ett gott vindfång, varför de lätt kan förstöras i hårt väder. However, such an arrangement requires great efforts both personally and materially. In addition, the tensioned plastic foils provide a good wind trap, so they can be easily destroyed in severe weather.

Huvudsyftet med uppfinningen är att åstadkomma en kas- sun av det inledningsvis nämnda slaget, vilken är förhållan- devis enkel till sin konstruktion och hantering samtidigt som den åstadkommer fullgod tätning av en fönsteröppning.The main object of the invention is to provide a case of the kind mentioned in the introduction, which is relatively simple in its construction and handling at the same time as it provides a complete sealing of a window opening.

Detta åstadkommas enligt uppfinningen genom att kassunen in- nefattar en hopfällbar, sluten och av ledbart med varandra förbundna ramstycken bestående ram som är så dimensionerad, att den i utfällt läge är anbringbar mot husfasaden utanför fönstoröppningen, minst en vid ramen - företrädesvis vid den sida, som är avsedd att vetta från fönsteröppningen - fäst och ramen överspännande folie eller liknande, en ytt- re stav eller motsvarande, anordnad att möjliggöra ingrepp mot ramen, en inre stav eller motsvarande, anordnad att möj- liggöra ingrepp mot husets insida, såsom vid en fönsterkarm och/eller en fönsterbänk eller liknande, samt minst ett mellan stavarna verkande spänndon, avsett att vid montering av kassunen möjliggöra anpressning av stavarna mot varand- ra, varvid ramen spänns fast och kvarhålles i läge mot hus- fasaden.This is achieved according to the invention in that the box comprises a collapsible, closed frame consisting of hingedly interconnected frame pieces which is dimensioned so that it is foldable in the unfolded position against the house facade outside the window opening, at least one at the frame - preferably at that side, intended to face from the window opening - fastening and the frame spanning foil or the like, an outer rod or the like, arranged to enable engagement with the frame, an inner rod or the like, arranged to enable engagement against the inside of the housing, as in a window frame and / or a window sill or the like, and at least one clamping device acting between the bars, intended to enable the bars to be pressed against each other when mounting the box, whereby the frame is clamped and held in position against the house facade.

Kassunen skall lämpligen vara så utformad, att den från ett rum i huset i hopfällt läge kan skjutas ut genom föns- teröppningen. Detta kan åstadkommas genom att den av fyra vid ändarna ledbart med varandra förbundna ramstycken be- stående ramen i utfällt läge har väsentligen rektangulär form samt att tvâ av de mot varandra vettande ramstyckena var för sig är delade i tvärriktningen i tvâ delar, som är ledbart förbundna med varandra vid angränsande ändar, så att hela ramen är hoppfällbar till ett kompakt paket genom att motstâende ramstycken föres mot varandra under vrid- ning - gângjärnsverkan - vid resp ledställen, varvid nämn- da folie erhåller formen av en påse eller säck vid pake- tets ena sida.The casing should suitably be designed so that it can be pushed out through a window in a folded position from a room in the house. This can be achieved in that the frame consisting of four frame pieces hingedly connected to each other in the unfolded position has a substantially rectangular shape and that two of the frame pieces facing each other are each divided in the transverse direction into two parts which are hingedly connected. with each other at adjacent ends, so that the whole frame can be folded into a compact package by moving opposite frame pieces towards each other during rotation - hinge action - at the respective articulation points, said foil obtaining the shape of a bag or sack at the package. one side.

Uppfinningen kommer att beskrivas närmare nedan i form av ett föredraget utföringsexempel under hänvisning 20 25 30 35 8200785-7 till den bifogade ritningen.The invention will be described in more detail below in the form of a preferred embodiment with reference to 8200785-7 to the accompanying drawing.

Figur 1 visar en framifrån sedd vy av en enligt upp- finningens principer utformad fönsterkassun, varvid ramen åskådliggöres i utfällt läge.Figure 1 shows a front view of a window box designed according to the principles of the invention, the frame being illustrated in the unfolded position.

Figur 2 visar en tvärsektion från sidan av den en- ligt figur 1 âskâdliggjorda kassunen, som är temporärt an- bringad i anslutning till en fönsteröppning.Figure 2 shows a cross section from the side of the cassette damaged according to figure 1, which is temporarily fitted in connection with a window opening.

Figur 3 visar i perspektivvy kassunens ram i hopfällt läge.Figure 3 shows in perspective view the frame of the cash register in the folded position.

Den pâ ritningen âskådliggjorda kassunen 10 består av en sluten rektangulär ram, innefattande fyra skivformiga ramstycken 14, 16, 18, 20. Ramstyckena kan med fördel vara tillverkade av glasfiberförstärkt frigolit. Vid ändarna är de sins emellan ledbart förbundna, så att ramens djup är större än dess bredd. Varje ledförbindning 22, 24, 26, 28 består av ett eller flera skikt av glasfiberväv, som appli- ceras vid förbindningsstället i anslutning till ramens 12 insida. Förutom de fyra ledförbindningarna vid ramstyckenas skarvställen finns ytterligare två ledförbindningar 30, 32 ungefär vid mitten av de motsatt belägna ramstyckena 18, 20.The box 10 shown in the drawing consists of a closed rectangular frame, comprising four disc-shaped frame pieces 14, 16, 18, 20. The frame pieces can advantageously be made of glass fiber-reinforced styrofoam. At the ends, they are hingedly connected to each other, so that the depth of the frame is greater than its width. Each hinge connection 22, 24, 26, 28 consists of one or more layers of fiberglass fabric, which are applied at the connection point adjacent to the inside of the frame 12. In addition to the four hinges at the joint points of the frame pieces, there are two further hinges 30, 32 approximately at the middle of the opposite frame pieces 18, 20.

Dessa ramstycken 18, 20 är sålunda delade i tvärriktningen i tvâ delar 18', 18" resp 20', 20". Ledförbindningarna 30, 32 utgöres även i detta fall av skikt av glasfiberväv men de är här anordnade vid ramens 12 utsida. Genom anordnande av ledförbindningar på detta sätt kan ramen med ett enkelt hand- grepp fällas ut frân hopfällt läge. Härvid erfordras endast att man griper tag i en av det övre ramstyckets 18 delar 18', 18". Ramen 12 faller då ut och intar genom tyngdkraftens ver- kan omedelbart den i figur 1 visade formen.These frame pieces 18, 20 are thus divided in the transverse direction into two parts 18 ', 18 "and 20', 20", respectively. The hinge connections 30, 32 also in this case consist of layers of fiberglass fabric, but they are here arranged at the outside of the frame 12. By arranging hinge connections in this way, the frame can be folded out of the folded position with a simple hand grip. In this case, it is only required to grasp one of the parts 18 ', 18 "of the upper frame piece 18. The frame 12 then falls out and, by the action of gravity, immediately assumes the shape shown in figure 1.

En ramen 12 överspännande glasfiberförstärkt plastfo- lie 34 är fastsatt vid ramen vid den sida, som är avsedd att vetta från en fönsteröppning 36. Plastfolien 34 skall, då ramen är utfälld, vara väl sträckt mellan ramstyckena 14, 16, 18, 20 och åstadkomma god tätning mot dessa. Lämpligen utnyttjas en dubbel plastfolie mellan ramstyckena. Härvid är, såsom framgår av figur 1, nylonband 38, 40 inplacerade mellan de bäda glasfiberförstärkta folieskikten, så en luft- 10 15 20 30 35 8200785-7 spalt erhålles mellan dessa. Isoleringen blir på detta sätt mycket god. Då kassunen 10 är hopfälld bildar folie- skikten en påse eller säck (visas icke) vid ramdelarnas ena sida.A frame 12 spanning glass fiber reinforced plastic film 34 is attached to the frame at the side intended to face from a window opening 36. When the frame is unfolded, the plastic film 34 should be well stretched between the frame pieces 14, 16, 18, 20 and provide good seal against these. A double plastic foil is suitably used between the frame pieces. In this case, as can be seen from Figure 1, nylon strips 38, 40 are placed between the two glass fiber-reinforced foil layers, so that an air gap is obtained between them. The insulation is very good in this way. When the box 10 is folded, the foil layers form a bag or sack (not shown) on one side of the frame parts.

Vid fastspänning av kassunen utnyttjas tvâ lättme- tallstavar 42, 44, som vid den visade utföringsformen har rektangulärt tvärsnitt, samt ett mellan dessa verkande spänn- don 46. Den yttre staven 42 har vid vardera änden mividgad platt del 48 resp 50, som är utformad för ingrepp vid ra- mens bakkant mellan själva ramen 12 och plastfolien 34. Sta- ven 42 sträcker sig mellan de två motsatt belägna, delade ramstyckena 18, 2D. Den inre staven 44 är längre än den ytt- re och utformad för att möjliggöra ingrepp mot insidan av ett hus. Den avsedda monteringen av stavarna 42, 44 framgar speciellt av figur 2. Kassunramen hålles härvid pressad mot en husfasad 52 utanför själva fönsteröppningen 36, varvid den inre staven 44 upptill anpressar mot det väggparti i rummet, som befinner sig omedelbart ovanför fönsteröppningen 36. Den inre staven 44 anpressar nedtill mot en fönsterbräda 54. Lämplig anpressningskraft ästadkommes med hjälp av den såsom spänndon verkande gummistroppen 46. Stroppen 46 är fastsatt ungefär vid mitten av den yttre staven 42 och är medelst en hâllkrok 56 fasthakad vid den inre staven 44.When clamping the box, two light metal rods 42, 44 are used, which in the embodiment shown have a rectangular cross-section, and a clamping member 46 acting between them. The outer rod 42 has at each end a flattened flat part 48 and 50, respectively, which is formed for engagement at the trailing edge of the frame between the frame 12 itself and the plastic foil 34. The rod 42 extends between the two opposite, divided frame pieces 18, 2D. The inner rod 44 is longer than the outer one and is designed to allow engagement with the inside of a housing. The intended mounting of the rods 42, 44 is shown in particular in Figure 2. The box frame is kept pressed against a housing facade 52 outside the window opening 36 itself, the inner rod 44 at the top pressing against the wall portion in the room which is immediately above the window opening 36. The inner the rod 44 is pressed downwards against a window sill 54. Appropriate pressing force is provided by means of the rubber strap 46 acting as a clamp. The strap 46 is fastened approximately to the middle of the outer rod 42 and is hooked to the inner rod 44 by means of a holding hook 56.

Stroppen skall vara så dimensionerad att den glasfiberför- stärkta frigolitramen 12 hâlles kvar mot husfasaden 52 med god anpressning. Den mot fönstret vettande änden av strop- pen har en förlängning 58 framför hâllkroken 56, vilken för- längning 58 är utformad med ett enkelt handtag 60, som gör det möjligt att lätt gripa stroppen 46 och spänna ut den i önskad längd. Hâllkroken 56 kan vara förflyttbar utmed strop- pen för fixering i önskat läge, så att konstruktionen kan användas för fönsteröppningar med olika djup.The strap must be dimensioned so that the fiberglass-reinforced styrofoam frame 12 is held against the house facade 52 with good pressing. The window-facing end of the strap has an extension 58 in front of the holding hook 56, which extension 58 is formed with a simple handle 60, which makes it possible to easily grip the strap 46 and stretch it to the desired length. The holding hook 56 can be movable along the strap for fixing in the desired position, so that the construction can be used for window openings with different depths.

För åstadkommande av fullgod tätning mellan ramen 12 och husfasaden 52 är ramens mot husfasaden vettande sida be- klädd med en skumgummilist 62. Härigenom förhindras också att husfasaden 52 skadas.In order to provide a complete seal between the frame 12 and the house façade 52, the side facing the house façade is covered with a foam rubber strip 62. This also prevents the house façade 52 from being damaged.

Vid den mot husfasaden vettande sidan av ramen finns också fyra likadanavinkelfästen 64, som är försedda med var 15 8200785-7 -sitt genomgående hål 66. Dessa fästen 64 kan med fördel ut- nyttjas i samband med mycket långvarig tillslutning av en fönsteröppning 36. Härvid användes icke visade spikar eller skruvar, som föres genom hålen 66 och drives in på vanligt sätt direkt i husfasaden.At the side of the frame facing the house façade there are also four identical angle brackets 64, which are provided with holes 66 each, these brackets 64. used nails or screws, which are passed through the holes 66 and driven in the usual way directly into the house facade.

Den i figur 3 âskâdliggjorda kassunramen innefattar två identiskt likadana hela ramstycken 14, 16 och två iden- tiskt likadana delade ramstycken 18, 20. Såsom framgår av ritningen har ramen 12 ett förhållandevis stort djup. Detta bör uppgå till mellan approximativt 10 - 20 cm. Härigenom blir det möjligt att utföra fönsterarbete förhållandevis fritt utan att fönsteröppningens 36 plastfolie (visas ej i figur 3), som befinner sig vid ramens utåt vettande sida, stör arbetet.The box frame damaged in Figure 3 comprises two identically identical whole frame pieces 14, 16 and two identically equally divided frame pieces 18, 20. As can be seen from the drawing, the frame 12 has a relatively large depth. This should amount to between approximately 10 - 20 cm. This makes it possible to carry out window work relatively freely without the plastic foil of the window opening 36 (not shown in Figure 3), which is located at the outwardly facing side of the frame, interfering with the work.

Modifikationer av den ovan beskrivna anordningen kan naturligtvis göras inom uppfinningens ram. Ramstyckenas form och antal kan varieras. Detsamma gäller för stavarna. I vis- sa fall, speciellt vid stora fönsteröppningar, kan det vara lämpligt att utnyttja mer än en spännstropp.Modifications of the device described above can of course be made within the scope of the invention. The shape and number of frame pieces can be varied. The same goes for the rods. In some cases, especially with large window openings, it may be appropriate to use more than one tensioning strap.
