Opfindelsen angår en dobbelt foldevæg af den kendte art, som består af to panelsæt, der hvert er sammensat af ved deres lodrette sidekanter med hinanden sammenhængslede paneler, og som ved hjælp af 5 boggier med lodrette drejeakser foroven er således ophængt i hver sin af to med hinanden parallelle køre-og styreskinner, at de under ét er bevægelige mellem en udfoldet stilling eller planstilling, i hvilken de to panelsæt har et indbyrdes mellemrum, og en folde-10 stilling, i hvilken panelerne er drejet ca. 90° om lodrette akser, regnet fra planstillingen.BACKGROUND OF THE INVENTION The invention relates to a double folding wall of the known kind, consisting of two panel sets, each of which is composed at their vertical side edges with interconnected panels, and which, by means of 5 bogies with vertical pivot axes, are thus suspended in each of two parallel running and guide rails, that they are simultaneously movable between an unfolded position or plane position in which the two panel sets have a mutual spacing, and a folding position in which the panels are rotated approx. 90 ° about vertical axes, calculated from the plane position.

Foldevægge har gennem en årrække været anvendt til variabel ruminddeling, navnlig i bygninger, der anvendes til hotel- og restaurationsvirksomhed, men 15 vinder i stigende grad også indpas i private boliger.Folding walls have for a number of years been used for variable room division, especially in buildings used for hotel and restaurant activities, but 15 are increasingly gaining access to private housing.

Et alvorligt problem i forbindelse med foldevægge er, at de på samme tid skal have en forholdsvis lille vægt af hensyn til deres nemme manøvrering og en tilfredsstillende lydtæthed i planstillingen eller luk-20 kestillingen. Disse to hensyn er ikke umiddelbart forenelige, eftersom lydtætheden ved foldevægge bestående af kun ét panelsæt fordrer, at dettes enkelte paneler har en betydelig tykkelse og vægt.A serious problem with folding walls is that they must at the same time have a relatively small weight for their easy maneuvering and satisfactory sound density in the flat or closing position. These two considerations are not immediately compatible since the sound density of folding walls consisting of only one panel set requires that its individual panels have a considerable thickness and weight.

I bestræbelserne på opnåelse af større lyd-25 tæthed er man gået over til dobbelte foldevægge, altså sådanne bestående af to panelsæt, der i planstillingen danner et lydabsorberende mellemrum, og som kan sammenfoldes på harmonikalignende måde. I en kendt konstruktion af denne art består hver side af den 30 dobbelte foldevæg af et antal parvis sammenhørende paneler, der er sammenhængslet med hinanden langs deres sammenstødende, lodrette sidekanter og ved de øvrige, lodrette sidekanter er hængslet til bærende søjler, som under bibeholdelse af deres lodrette stil-35 ling er forskydelige i loft- og gulvskinner. For at foldevæggens fremstilling og montering samt dens manøvrering ikke skal blive for besværlig, er de omtalte 2 1413 Λ 3 søjler fælles for de to vægsider eller de to sæt panelelementer, og det kan herved ikke undgås, at søjlerne i ganske væsentlig grad reducerer foldevæggens lydisolationsvirkning, eftersom søjlerne danner lydbroer 5 mellem de to vægsider i planstillingen. I visse tilfælde er det en yderligere ulempe ved den kendte konstruktion, at foldevæggen i sin sammenfoldede stilling har en dybde eller tykkelse, der overstiger det dobbelte af bredden af hvert panel.In the effort to achieve greater sound density, they have gone to double folding walls, that is to say, consisting of two panel sets, which in the floor plan form a sound-absorbing space and which can be folded together in a harmonic-like manner. In a known construction of this kind, each side of the 30 double fold wall consists of a plurality of pairs of interconnected panels which are interconnected along their adjacent vertical side edges and at the other vertical side edges are hinged to supporting columns which, while retaining their vertical position is slidable in ceiling and floor rails. In order not to make the folding wall's manufacture and mounting as well as its maneuvering too difficult, the aforementioned 2 1413 Λ 3 columns are common to the two wall sides or the two sets of panel elements, and it cannot be avoided that the columns significantly reduce the sound insulation effect of the fold wall. , since the columns form sound bridges 5 between the two wall sides in the plane position. In some cases, a further disadvantage of the known construction is that the folding wall in its collapsed position has a depth or thickness exceeding twice the width of each panel.

10 Fra den forklarede kendte teknik adskiller den dobbelte foldevæg ifølge opfindelsen sig ved, at afstanden mellem de to køre- og styreskinner er mindre end panelernes bredde, og at hvert andet kanthængsel i hvert panelsæt har sin akse liggende hoved-15 sagelig i plan méd eller uden for panelernes yderside, medens de øvrige kanthængslers akser ligger forsat mindst et til paneltykkelsen svarende stykke indad fra panelernes inderside, hvorhos hvert indad forsat kanthængsel i hvert panelsæt ligger ud for et yder-20 side-kanthængsel i det andet panelsæt.10 From the prior art explained, the double folding wall according to the invention differs in that the distance between the two drive and guide rails is less than the width of the panels and that every other edge hinge in each panel set has its axis lying substantially flat with or outside the outside of the panels, while the axes of the other edge hinges are positioned at least one piece corresponding to the panel thickness from the inside of the panels, each inner edge hinge of each panel set being adjacent to an outer side edge hinge of the other panel set.

I dette tilfælde kan foldevæggens to sider eller to panelsæt være helt uden lydoverførende forbindelse med hinanden, og ved væggens sammenfoldning fra planstillingen kan panelerne i det ene sæt glide delvis 25 ind mellem panelerne i det andet sæt, så at den samlede dybde eller tykkelse af den sammenfoldede væg ikke behøver at være ret meget større end panelbredden. Trods afsavnet af fælles, bærende søjler for de to sider eller panelsæt kan der endvidere ved enkle midler dra-30 ges omsorg for, at disse panelsæt kan stabiliseres under ét i såvel yderstillingerne som en vilkårlig mellemstilling, ligesom deres bevægelser kan koordineres, så at panelerne ved væggens sammenfoldning glider ind mellem hinanden på den tilsigtede måde.In this case, the two sides or two panel sets of the folding wall may be completely without sound-transmitting connection to each other, and upon folding the wall from the plane position, the panels in one set may slide partially between the panels in the other set, so that the total depth or thickness of the folded wall does not have to be much larger than the panel width. Moreover, despite the absence of common supporting columns for the two sides or panel sets, it is possible by simple means to ensure that these panel sets can be stabilized together in both the outer positions and any intermediate position, as well as their movements can be coordinated so that the panels at the folding of the wall, slide in between each other in the intended manner.

35 Ved den for opfindelsen særegne udformning af den dobbelte foldevæg er der således skabt mulighed 3 141343 for på enkel og hensigtsmæssig måde at tilgodese også betjeningsraæssige hensyn af praktisk betydning.Thus, in the particular design of the double folding wall for the invention, an opportunity has been provided to provide for simple and convenient ways of serving operational considerations in a simple and appropriate way.

Eksempelvis er det ønskeligt, at foldevæggen har tilbøjelighed til at forblive i henholdsvis den 5 sammenfoldede og den plane stilling, så at tilfældige påvirkninger, s&som lette stød eller lufttræk, ikke får den til at forlade den pågældende stilling.For example, it is desirable that the folding wall tends to remain in the collapsed and planar positions, respectively, so that random influences, such as light shocks or traits, do not cause it to leave that position.

Dette kan ved konstruktionen ifølge opfindelsen såre enkelt opnås ved, at de to panelsæts parvis ud 10 for hinanden liggende paneler er forbundet med hinanden ved hjælp af elastiske snore eller lignende fjedre, hvis fæstepunkter er beliggende mellem de pågældende panelers lodrette boggieakser og deres indad forsatte kanthængsler. Virkningen af dette arrangement skal 15 blive nærmere forklaret i den efterfølgende, detaljerede beskrivelse.This can be achieved easily in the construction according to the invention in that the two panels sets of pairs of 10 adjacent pairs are connected to each other by means of elastic cords or similar springs, whose fastening points are located between the vertical bogie axes of the panels concerned and their inwardly set edge hinges. . The effect of this arrangement will be explained in more detail in the following detailed description.

Et andet hensyn gælder foldevæggens manøvrering mellem de to stillinger og specielt dens åbning ved bevægelse fra den plane til den sammenfoldede 20 stilling. Denne bevægelse skal kunne initieres ved et indadrettet tryk på et vilkårligt af de to panelsæt ved eller i nærheden af et af dettes yderside-kant-hængsler. Ved det angivne hængselarrangement vil den således indledte sammenfoldning automatisk for-25 plante sig til de øvrige paneler i samme panelsæt, men det må yderligere foretrækkes, at også det andet panelsæt straks følger med i sammenfoldningsbevægelsen. Dette kan ved den dobbelte foldevæg med det foran forklarede hængselarrangement sikres ved, at i hvert fald 30 nogle af de to panelsæts parvis ud for hinanden liggende paneler er forbundet med hinanden gennem fleksible, hovedsagelig ustrækkelige snore eller lignende trækforbindelser, hvis fæstepunkter ligger ud for hinanden og i nærheden af panelernes sidekanter, og hvis 35 længde er en smule større end afstanden mellem disse fæstepunkter i foldevæggens planstilling. Også denne 141343 4 særforanstaltnings funktion skal blive nærmere forklaret i den detaljerede beskrivelse.Another consideration concerns the maneuvering of the folding wall between the two positions and, in particular, its opening by movement from the plane to the folded position. This movement must be initiated by an inward pressure on any of the two panel sets at or near one of its outer edge hinges. At the specified hinge arrangement, the folding thus initiated will automatically propagate to the other panels in the same panel set, but it is further preferred that the second panel set also immediately follows the folding movement. This can be ensured by the double folding wall with the aforementioned hinge arrangement, in that at least 30 of each of the two sets of panels, which are in pairs adjacent to each other, are connected to each other through flexible, generally unstretchable cords or similar tensile connections, the attachment points of which are adjacent to each other. and near the side edges of the panels, the length of which is slightly greater than the distance between these attachment points in the fold position of the folding wall. The function of this special measure must also be explained in more detail in the detailed description.

Til yderligere fiksering af foldevæggens to panelsæt under ét, henholdsvis lettelse af deres bevæ-5 gelse mellem de to yderstillinger, foretrækkes det ifølge opfindelsen, at de to køre- og styreskinner under ét er lodret bevægelige mellem en nedre hvilestilling, i hvilken panelerne er stabiliseret ved med deres underkant at hvile mod en understøtning, fortrinsvis en 10 nedre styreskinne, og en øvre kørestilling, i hvilken panelerne er løftet fri af understøtningen. I praksis kan de to køre- og styreskinner i dette tilfælde hensigtsmæssigt være ophængt i en fælles bærer, der hviler på et oppumpeligt slangestykke med tilnærmelsesvis 15 samme længde som skinnerne.In order to further fix the two panel sets of the folding wall together, or to facilitate their movement between the two outer positions, respectively, it is preferred according to the invention that the two driving and guide rails together are vertically movable between a lower rest position in which the panels are stabilized. by resting with their lower edge against a support, preferably a lower guide rail, and an upper driving position in which the panels are lifted free of the support. In practice, in this case, the two drive and guide rails may conveniently be suspended in a common carrier resting on an inflatable hose piece of approximately the same length as the rails.

Foretrukne udførelsesformer for foldevæggen ifølge opfindelsen med de foran angivne særforanstaltninger er vist på tegningen, hvor fig. 1 viser et sidebillede af en del af en 20 foldevæg ifølge opfindelsen og med dele af det ene panelsæt fjernet samt med et indtegnet vandret snit i væggen, fig. 2 et brudt, lodret tværsnit gennem væggen i planstillingen, idet snittets venstre side viser 25 væggen i en nedre, stabil stilling, medens højre side viser væggen løftet som forberedelse til sammenskydning eller sammenfoldning, fig. 3 en del af et vandret snit gennem væggen under dennes sammenfoldning, 30 fig. 4 et tilsvarende snit af den komplette væg efter fuld sammenfoldning, og fig. 5 den ene halvdel af et snit i væsentlig større målestoksforhold gennem foldevæggens overkarm.Preferred embodiments of the folding wall according to the invention with the above-mentioned special measures are shown in the drawing, in which fig. 1 is a side view of a portion of a folding wall according to the invention and with parts of one panel set removed as well as with a horizontal horizontal section of the wall; FIG. 2 is a broken vertical cross section through the wall in the plane position, the left side of the section showing the wall in a lower, stable position, while the right side showing the wall lifted in preparation for jointing or folding; FIG. 3 is a section of a horizontal section through the wall during the folding thereof, FIG. 4 shows a corresponding section of the complete wall after full folding; and FIG. 5 shows one half of a section in substantially larger scale ratios through the upper frame of the folding wall.

I den på tegningen viste udførelsesform for 35 den dobbelte foldevæg ifølge opfindelsen er denne indbygget i en karm bestående af en underpart 1, en 5 141343 overpart 2 og to sideparter 3. Som vist kan hver af disse karmparter være sammensat af to hovedsagelig ens dele, mellem hvilke der er levnet en luftspalte 4 til at hindre eller modvirke lydforplantning gennem 5 de forskellige karmparter.In the embodiment of the double folding wall according to the invention shown in the drawing, it is built into a frame consisting of a subpart 1, a top part 2 and two side parts 3. As shown, each of these frame parts can be composed of two substantially equal parts. between which is left an air gap 4 to prevent or discourage sound propagation through 5 the various sill parts.

Selve foldevæggen består af to sæt rektangulære paneler 5 og 6, der danner henholdsvis den ene og den anden side af foldevæggen i dennes planstilling, fig. 1, og som inden for hvert sæt parvis er sammen-10 hængslet med hinanden langs deres lodrette sidekanter, som det bedst fremgår af fig. 3 og 4, De hertil anvendte kanthængsler 7a og 7b kan være såkaldte pianohængsler eller kan udgøres af ligeledes velkendte båndhængsler af et passende plastmateriale. Hængsler-15 ne 7b har deres akser liggende hovedsagelig i plan med ydersiden af de tilhørende paneler 5 eller 6, medens hængslerne 7a er således anbragt, at deres akser regnet fra panelernes inderside ligger forskudt et stykke indad svarende tilnærmelsesvis til 20 tykkelsen af panelerne. Herved muliggøres en tæt sammens tab ling af panelerne 5 og 6 i væggens sammenfoldede stilling, se fig. 4.The folding wall itself consists of two sets of rectangular panels 5 and 6, which form one and the other side of the folding wall respectively in its plane position. 1, and which, within each set of pairs, are interconnected with one another along their vertical side edges, as best seen in FIG. 3 and 4, The edge hinges 7a and 7b used for this purpose may be so-called piano hinges or may also be well-known band hinges of a suitable plastic material. The hinges 7b 7b have their axes lying substantially flush with the outside of the associated panels 5 or 6, while the hinges 7a are arranged such that their axes, calculated from the inside of the panels, are displaced a distance inward approximately to the thickness of the panels. This allows a close assembly of panels 5 and 6 in the folded position of the wall, see fig. 4th

Hvert panel 5 eller 6 er drejeligt om en lodret akse, der er sammenfaldende med eller ligger i nær-25 heden af panelets lodrette tyngdepunktsakse, og som er bestemt af dels en nedre styretap 8, som indgriber med en tilhørende bundskinne 9 for det pågældende panelsæt, dels en boggie 10, som løber i en øvre køre-og styreskinne 11, se navnlig fig. 5. De to køre- og 30 styreskinner 11 er fastgjort til en falles bærer 12, som hviler på et i karmoverparten 2 indlagt, op-pumpeligt slangestykke 13. I fig. 5 og i højre side af fig. 2 er slangestykket 13 vist oppumpet, f.eks. ved hjælp af trykluft tilført fra en ikke vist kompres-35 sor gennem en ledning 14, fig. 1, og bæreren 12 med de to køreskinner 11 er derved hævet så meget, 141343 6 at de i køreskinneme hængende paneler 5 og 6 er løftet så meget fri af den nedre karmpart 1, at bog-gierne 10 muliggør en så at sige uhindret forskydning og drejning af de to panelsæt 5 og 6. Ved 5 udslipning af trykmediet fra slangestykket 13 vil bæreren 12 og dermed selve foldevæggen sænkes så meget, at de forskellige paneler 5 og 6 med deres underkant kommer til at hvile på karmunderparten 1, se venstre side af fig. 2, og følgelig stabiliseres 10 i den indstillede stilling, sædvanligvis planstillingen eller den fuldt sammenfoldede stilling. Som regel vil vægten af foldevæggen være tilstrækkelig til iværksættelse af den nedadgående bevægelse, men som vist i fig. 5 og antydet i fig. 1 kan der mellem oversiden 15 af bæreren 12 og undersiden af karmoverpartens bærende element 15 være indskudt et yderligere oppum-peligt slangestykke 16.Each panel 5 or 6 is rotatable about a vertical axis that coincides with or is adjacent to the vertical axis of gravity of the panel, and is determined by a lower guide pin 8 which engages an associated bottom rail 9 for that panel set. , partly a bogie 10, which runs in an upper drive and guide rail 11, see in particular fig. 5. The two drive and guide rails 11 are attached to a dropped carrier 12, which rests on an inflatable hose piece 13 which is inserted into the frame upper part 2. 5 and on the right side of FIG. 2, the hose piece 13 is shown to be inflated, e.g. by means of compressed air supplied from a compressor not shown through a conduit 14, fig. 1, and the carrier 12 with the two running rails 11 is thereby raised so much that the panels 5 and 6 hanging in the running rails are lifted so much free from the lower frame part 1 that the bogies 10 allow an almost unobstructed displacement and turning the two panel sets 5 and 6. Upon release of the pressure medium from the hose piece 13, the carrier 12 and thus the folding wall itself will be lowered so much that the different panels 5 and 6 with their lower edge will rest on the frame bottom part 1, see left side of FIG. 2, and consequently 10 is stabilized in the set position, usually the plane position or the fully folded position. As a rule, the weight of the folding wall will be sufficient to effect the downward movement, but as shown in FIG. 5 and indicated in FIG. 1, a further inflatable hose piece 16 may be inserted between the upper surface 15 of the support 12 and the underside of the supporting member 15 of the frame member.

Til forbedring af lydtætheden ved karmover-parten 2 kan der mellem bæreren 12 og elementet 20 15 endvidere være indskudt fleksible pakningsstrimler 17, som vist i fig. 5.Furthermore, to improve the sound density at the frame member 2, there can be inserted between the carrier 12 and the element 20 flexible flexible packing strips 17, as shown in FIG. 5th

Til stabilisering af foldevæggen såvel i den helt sammenfoldede stilling, fig. 4, som i planstillingen, fig. 1, tjener elastiske snore 18 eller lig-25 nende fjedre, der hver for sig forbinder to ud for hinanden liggende paneler 5 og 6 hørende ti hver sit panelsæt, og hvis fæstepunkter ligger mellem de pågældende panelers lodrette drejeakser eller boggieak-ser og deres indad forsatte kanthængsler 7a. Uanset 30 om væggen skal sammenfoldes fra den i fig. 1 viste planstilling eller skal udfoldes fra den sammenstablede stilling i fig. 4, vil snorene 18 under den første del af bevægelsen resultere i voksende drejningsmomenter om dreje- eller boggieakserne, hvilket 35 er ensbetydende med, at disse snore stræber efter at fastholde foldevæggen i de to omtalte stillinger.For stabilizing the folding wall as well as in the fully folded position, fig. 4, as in the plane position, FIG. 1, elastic cords 18 or similar springs serve, each of which connects two adjacent panels 5 and 6 of each of its own panel set, and whose attachment points lie between the vertical pivots or bogie axes of the panels concerned and their inwards continued edge hinges 7a. Regardless of whether the wall is folded from the one shown in FIG. 1 or to be unfolded from the stacked position of FIG. 4, the cords 18 during the first part of the movement will result in increasing torque about the pivot or bogie axes, which means that these cords aim to maintain the folding wall in the two positions mentioned.

Claims

At initial folding from the plane position, the increasing torque is due to the string 18 being stretched (while the moment arms are only shortened infinitesimally), while at initial unfolding 5 there is an increase of the momentarra (accompanied by an infinitesimal stretch of the string 18 only). In addition, the two panel sets paired opposite each other 5 and 6, or at least some of these panel pairs, are connected to each other through 10 flexible, mostly unstretchable cords 19, the attachment points of the panels being adjacent and adjacent to the side edges of the panels. , and the length of which is slightly greater than the distance between these attachment points in the fold position of the fold wall, Fig. 1. The purpose of these cords 19 is to coordinate the movement of the two panels during unfolding and folding, and to propagate the movement over the entire width of the wall. is best realized if you intend to exert an inward (in the drawing downward) 20 press at the edge hinge indicated by 7b in the horizontal section of FIG. In that case, the 5 'panel referred to will directly impart a clockwise rotation about the vertical center axis, and through the string 19 at the left side-25 edge of that panel, the 6' panel designated as the second panel set will be forced to make a corresponding turn. The FIG. 1, leash 19 will act in the same way when a pressure is applied at the left side edge of panel 5 *. 30 PATENT REQUIREMENTS
