Description
, DK 174572 B1, DK 174572 B1
Den foreliggende opfindelse vedrører en afskærmningsindretning, navnlig en vinduesafskærmning til montering i en vinduesåbning, omfattende eksempelvis en ophængningsstok og en til stokken forbundet oprullet eller sammenfoldelig dug, hvilken dug ved dugens nedre frie ende er forbundet med en bundstok, der strækker sig mellem 5 vinduesåbningens ramme- eller karmsidestykker, og hvilken afskærmning endvidere er styret ved hjælp af et til parallelføring af dugen tilvejebragt snorarrangement med i det mindste to separate snore, som fra et første sæt fastgørelseselementer anbragt øverst i vinduesåbningen i det mindste er ført gennem nævnte bund stok til vinduesåbningens modsatte ramme- eller karmsidestykker ved dennes bund, og fastgjort hertil med et 10 andet sæt fastgørelseselementer.BACKGROUND OF THE INVENTION The present invention relates to a screening device, in particular a window cover for mounting in a window opening, comprising, for example, a hanging cane and a rolled or foldable tab connected to the cane, which tab at the lower free end of the tab is connected to a bottom bar extending between the window opening frame. - or frame side pieces, and which shielding is further controlled by a string arrangement provided for parallelizing the tablecloth with at least two separate cords, which from a first set of fastening elements placed at the top of the window opening at least through the bottom floor stick to the opposite of the window opening. frame or frame side pieces at the bottom thereof, and secured thereto with a second set of fasteners.
Ved afskærmningsindretninger til montering i en vinduesåbning, hvor ophængningsstokken er fastholdt ved vinduesåbningens ramme eller karmtopstykke anvender man sædvanligvis et snorarrangement af ovennævnte type til parallelføring af bundstokken og dermed afskærmningen, så denne føres parallelt i forhold til vinduesis åbningens ramme eller karmtop- og bundstykker, og med mindst mulig vertikal forskydning af bund stokkens ender.In the case of shielding devices for mounting in a window opening, where the suspension stick is held by the frame or frame of the window opening, a string arrangement of the above type is usually used to parallel the base and thus the shield, so that it is run parallel to the frame or bottom of the window frame and with as little vertical displacement as the bottom end of the log.
I andre tilfælde, hvor ophængningsstokken ligesom bundstokken er frit bevægelig i forhold til vinduesåbningens ramme eller karmtop- og bundstykker, dvs. hvor dugen valgfrit kan placeres i vinduesåbningen, og navnlig i de tilfælde, hvor afskærm-20 ningen skal anvendes i et ovenlysvindue anbragt i et skråtag, er det almindeligt at anvende et snorarrangement omfattende to eller fire separate snore, der dels føres gennem den nævnte ophængningsstok til parallelføring af denne, dels fungerer som stabil-seringssnore for dugen, på en sådan måde, at dugen holdes stramt oppe og således ikke buer nedad.In other cases where, like the base, the suspension can be freely movable relative to the window opening frame or frame tops and bases, ie. where the tablecloth can optionally be placed in the window opening, and especially in cases where the screen is to be used in a skylight arranged in a sloping roof, it is common to use a string arrangement comprising two or four separate cords, which is partly passed through said suspension bar. for parallel guiding this, partly serves as a stabilizing cord for the tablecloth, in such a way that the tablecloth is held tightly up and thus not curved downwards.
25 For at muliggøre en fastholdelse af bundstokken, særligt i dens bundstilling men også i et antal mellemstillinger, kendes der eksempelvis ffa DK patentansøgning nr. PA 1992 00322 (tilhørende ansøgeren) en afskærmningsindretning af ovennævnte type, hvor en permanent virkende bremseindretning fastholder bundstokken i en vilkårlig stilling mod virkningen af en fjederforspændt rullestok, hvilken bremseindret-30 ning omfatter et i bundstokken monteret og på snorarrangementet permanent virkende ffiktionsarrangement, og hvor der tillige i tilslutning til nævnte fastgørelseselementer findes en fjeder til stramning af snoren.For enabling the holding of the base, especially in its base position but also in a number of intermediate positions, for example, ffa DK patent application No. PA 1992 00322 (associated with the applicant) discloses a shielding device of the above-mentioned type, in which a permanently acting brake device holds the base arbitrary position against the action of a spring-biased roller bar, the braking device comprising a fixing arrangement mounted on the base and permanently operating on the string arrangement, and a spring for tightening the string in addition to said fastening elements.
En anden mulig måde at fastholde en bundstok, særligt i dens bundstilling men 2 DK 174572 B1 også i et antal mellemstillinger, kendes eksempelvis fra US patent nr. 1 766 730, hvor en bundstok forsynes med en udløselig fastholdelsesmekanisme, der betjenes gennem en i bundstokken anbragt fjederpåvirket pal, der kan bringes i indgreb med et antal i vinduesåbningens sidestykker tilvejebragte åbninger, hvorved bundstokken kan parke-5 res i et tilsvarende antal forudfastlagte stillinger. Denne kendte fastholdelsesmekanisme har imidlertid den svaghed, at den dels skal aktiveres manuelt af brugeren ved hvert ønsket fastholdelses position, dels stiller store montagekrav til placeringen af åbningerne i præcis samme højde i sidestykkerne, hvilket giver et relativt dyrt og ressourcekrævende produkt.Another possible way of holding a base, especially in its bottom position, but also in a number of intermediate positions, is known, for example, from US Patent No. 1 766 730, where a base is provided with a releasable retaining mechanism which is operated through an in the base disposed spring-loaded pawl which can be engaged by a number of apertures provided in the side apertures of the window opening, whereby the base can be parked in a corresponding number of predetermined positions. However, this known retaining mechanism has the weakness that it must be manually activated by the user at each desired retention position, and partly imposes high mounting requirements for the placement of the openings at exactly the same height in the side pieces, which provides a relatively expensive and resource-consuming product.
10 Samtidig er det erkendt, at navnlig i forbindelse med afskærmningsarrange menter af den type, hvor dugen valgfrit kan anbringes i en vilkårlig stilling i vinduesåbningen, og hvor toleranceafvigelser eller slidtage, men også i andre tilfælde, så kan bremseindretningens funktionalitet svigte, dvs. fastholdelsen af bundstokken ikke udgør en permanent funktion, hvilket i relation til forbrugeren af produktet opfattes som 15 en funktionsfejl og dermed på sigt resulterer i en væsentlig reduktion af betjeningskomforten,10 At the same time, it is recognized that in particular in connection with shielding arrangements of the type in which the tablecloth can be optionally placed in any position in the window opening and where tolerance deviations or wear, but also in other cases, the functionality of the braking device may fail, ie. the holding of the base does not constitute a permanent function, which in relation to the consumer of the product is perceived as a malfunction and thus in the long term results in a substantial reduction in operating comfort,
Det er i forhold hertil et formål med opfindelsen at tilvejebringe en afskærmningsindretning, der giver mulighed for på en simpel måde at kunne fastholde bundstokken og dermed afskærmningsindretningen i vilkårlige stillinger mellem vinduesåb-20 ningens top- og bundstykker, ikke mindst for at få en korrekt ophængt dug i forbindelse med duge, der valgfrit kan anbringes i en vilkårlig stilling i vinduesåbningen, og som giver et æstetisk tiltalende helhedsindtryk af afskærmningen, samtidig med at forbrugeren oplever en øget betjeningskomfort uanset hvor i vinduesåbningen afskærmningen er placeret.Accordingly, it is an object of the invention to provide a shielding device which allows for a simple way of holding the base and thus the shielding device in any position between the window and top pieces of the window opening, not least to get a correctly suspended tablecloth in connection with tablecloths that can be optionally placed in any position in the window opening, which gives an aesthetically pleasing overall impression of the screen, while at the same time the consumer experiences an increased operating comfort wherever the window opening is located.
25 Med henblik herpå er afskærmningsindretningen af den angivne type karakteri seret ved, at en bremseindretning til fastholdelse af bundstokken i en vilkårlig stilling omfatter et i bundstokken monteret og på snorarrangementet variabelt virkende friktionselement.To this end, the shielding device of the specified type is characterized in that a braking device for holding the base in any position comprises a friction element mounted in the base and variable on the string arrangement.
Med et sådan forholdsvis enkelt opbygget friktionselement, der påvirker sno-30 rarrangementet med en variabelt virkende friktionskraft opnår man den særlige virkning, at man kan kompensere for en manglende snorspænding opstået som følge af produktionstolerancer eller almindelig slidtage af snorarrangementet. Herved forbliver snorarrangementet i en forspændt tilstand med den virkning, at dugen altid fremstår 3 DK 174572 B1 helt udspændt og afskærmningen ikke af sig selv begynder at bevæge sig op eller ned.With such a relatively simple built-up friction element which affects the string arrangement with a variable acting frictional force, the special effect is obtained to compensate for a lack of string tension caused by production tolerances or ordinary wear of the string arrangement. In this way, the string arrangement remains in a biased state with the effect that the tab always appears fully tensioned and the shielding does not by itself move up or down.
Samtidig giver anvendelsen af det på snorarrangementet variabelt virkende friktions-element en vis bremsende effekt på snorene, hvilket betyder at betjeningskomforten øges, idet betjeningskraften kan nedsættes samtidig med at det stadig er muligt at par-5 kere afskærmningen i en vilkårlig position uafhængigt af om den er anbragt i en fast vinduesåbning eller en bevægelig vinduesramme. Hertil kommer at anvendelsen af et friktionselement i overensstemmelse med opfindelsen medvirker til, at de enkelte snore i snorarrangementet kan styres på en kontrolleret måde, så de ikke vikles ind i hinanden, hvilket også medvirker til en øget betjeningskomfort og -sikkerhed.At the same time, the use of the friction element variably acting on the leash arrangement provides some braking effect on the leashes, which means that the operating comfort is increased, since the operating force can be reduced while still allowing the shielding to be parked in any position regardless of whether the is arranged in a fixed window opening or a movable window frame. In addition, the use of a friction element in accordance with the invention helps the individual strings in the string arrangement to be controlled in a controlled manner so that they are not interlocked, which also contributes to increased operating comfort and safety.
I o I en anden hensigtsmæssig udførelsesform for opfindelsen kan det nævnte va riabelt virkende friktionselement samvirke med en snoropstramningsanordning anbragt i tilslutning til nævnte fastgørelseselementer.In another convenient embodiment of the invention, the said frictional actuating element may cooperate with a string tensioning device disposed adjacent to said fastening elements.
Med et sådan forholdsvis enkelt friktionselement, der påvirker snorarrangementet på den ovennævnte måde og som samvirker med den nævnte snoropstram-15 ningsanordning anbragt i tilslutning til nævnte fastgørelseselementer, har det vist sig muligt at opnå en veldefineret positionering af bundstokken, som for enhver parkerings position af bundstokken giver brugeren en tydelig indikering af, at den ønskede stilling er opnået gennem en ændring af betjeningskraften. Det er således vigtigt, at opstramningsanordningen sammen med det variabelt virkende friktionselement holder 20 snorene i snorarrangementet opstrammede, idet det er friktionselementet samvirken med opstramningsanordningen der giver den ønskede øgede betjeningskomfort.With such a relatively simple friction element which affects the string arrangement in the above manner and which cooperates with the said string tensioning device arranged adjacent to said fastening elements, it has been possible to achieve a well-defined positioning of the base, as for any parking position of the the base gives the user a clear indication that the desired position has been achieved through a change in the operating force. Thus, it is important that the tensioning device together with the variable-acting friction element keep the strings in the string arrangement tightened, with the friction element interacting with the tensioning device which provides the desired increased operating comfort.
I en anden særlig udførelsesform for opfindelsen anvender man to separate af-skærmningsarrangementer med hver sit snorarrangement til parallelføring af den enkelte dug, hvor den ene afskærmning eksempelvis kan udgøres af det tidligere nævnte 25 ^ederforspændte rullegardin anbragt øverst i en vinduesåbning, hvor dette rullegardins bundstok kobles sammen med en anden afskærmnings ophængningsstok, hvilken anden afskærmning kan være af den type nævnt indledningsvist med en ophængningsstok og en til denne forbundet dug, hvilken dug ved dugens nedre frie ende er forbundet med en bundstok med det nævnte variabelt virkende friktionselement.In another particular embodiment of the invention, two separate shielding arrangements are used, each with its own lanyard arrangement, for parallel guiding of the individual tablecloth, one of which can be formed, for example, by the aforementioned 25 ° biased roller blind placed at the top of a window opening where the base of this roller curtain is coupled with a second guard hanging rod, which second guard may be of the type mentioned initially with a hanging rod and a tablecloth connected thereto, which tablecloth at the lower free end of the tablecloth is connected to a bottom pole having said variable acting friction element.
30 Opfindelselsen skal nu forklares nærmere under henvisning til den medfølgen de skematiske tegning, på hvilken fig. 1 viser et vindue udstyret med et som plissegardin udført udførelsesform for en afskærmningsindretning i overensstemmelse med opfindelsen.The invention will now be explained in more detail with reference to the accompanying schematic drawing, in which fig. Figure 1 shows a window equipped with a screen curtain embodiment of a screening device according to the invention.

Ved den i fig, 1 viste vinduesafskærmning, der her udgøres af et plissegardin 10 (1) omfattende en ophængningsstok (2), som er ophængt frit bevægeligt i vinduesåb ningen, en ligeledes frit bevægelig bundstok (3), en mellem de to stokke udspændt og fastgjort plisseret dug (4), samt to separate snorarrangementer (5,6), som tilsammen udgør et parallelføringsarrangement for afskærmningen. Afskærmningen er her vist med et enkelt snorsystem omfattende de nævnte to separate snorarrangementer (5,6), 15 der foroven i vinduesåbningen fastholdes af to fastgørelseselementer (7,8) og forneden af to fastgørelseselementer (9,10). Til stabilisering af den plisserede dug (4) anvendes et antal stigesnore (11), der i princippet kan være fastgjort til en ikke vist oprulningsmekanisme i ophængningsstokken (2).In the window cover shown in Fig. 1, which is constituted here by a pleated curtain 10 (1) comprising a hanging bar (2) which is suspended freely movable in the window opening, a also freely movable base bar (3), a between the two sticks and fixed pleated tablecloth (4), as well as two separate string arrangements (5,6), which together constitute a parallel guiding arrangement for the shielding. The shielding is shown here with a single string system comprising said two separate string arrangements (5,6), which are held at the top of the window opening by two fastening elements (7,8) and at the bottom by two fastening elements (9,10). To stabilize the pleated tablecloth (4), a number of ladders (11) are used, which can in principle be attached to a winding mechanism (not shown) in the suspension log (2).
Som det fremgår af fig 2 og af hensyn til at opnå en så relativt simpel af-20 skærmningsindretning som muligt omfatter det i beskrivelsen og på tegningen viste plissegardin et snorsystem, hvor hver af de to separate snorarrangementer (5,6) består af to enkelte snore. Hvert snorarrangement (5,6) er foroven i vinduesåbningen fastgjort til hvert sit fastgørelseselement (7,8) og fortsætter parallelt med vinduesåbningens sidestykker ned til ophængningsstokken (2), som de løber ind i fra hver sin ende 25 med retning mod den modsatte ende. Senest et stykke inde i stokken (2) splittes sno-rarrangementeme (5,6) hver i to enkelte snore, dvs. til i alt fire snore, der hver for sig fortsætter ud gennem huller i stokkens bundflade og videre gennem huller i den plisserede dug (4) til opstramning af denne. Snorene udgør på denne måde samtidig stige-snorene (11) for dugen. Det er således muligt at undlade at anvende den før omtalte 30 oprulningsmekanisme. Fra dugens endestykke ved bundstokken (3) fortsætter snorene ind gennem huller i dennes topflade, hvor de igen samles til de nævnte snorarrangementer (5,6), og føres ud gennem hver sin ende i stokken (3) modsat i forhold til deres indføring i ophængningsstokken (2). Fra bundstokken (3) føres snorarrangemen- 5 DK 174572 B1 terne (5,6) igen ned parallelt langs med de modsatte sidestykker i vinduesåbningen og hen til to andre Fastgørelseselementer (9,10). Gennem denne fremføring af snorene i det samlede snorsystem fremkommer den føromtalte parallelføring af afskærmningsindretningen.As can be seen from Fig. 2 and for the purpose of obtaining as relatively simple a shielding device as possible, the pleated curtain shown in the description and in the drawing comprises a string system in which each of the two separate string arrangements (5,6) consists of two individual lace up. Each string arrangement (5,6) is fixed at the top of the window opening to each of its fastening elements (7,8) and proceeds parallel to the side portions of the window opening down to the suspension bar (2), which they extend from each end 25 towards the opposite end. . At least one piece inside the stick (2), the string arrangements (5,6) are each split into two single strings, ie. for a total of four cords, each extending out through holes in the bottom surface of the stick and further through holes in the pleated tablecloth (4) to tighten it. In this way, the cords form the ladder cords (11) for the tablecloth. Thus, it is possible to avoid using the aforementioned rewinding mechanism. From the end piece of the tab at the base (3), the cords continue through holes in the top surface thereof, where they are again assembled to said string arrangements (5,6) and are extended through each end of the stick (3) opposite to their introduction into the cage. the suspension stick (2). From the base (3), the string arrangements (5,6) are led down again parallel to the opposite side pieces in the window opening and to two other fastening elements (9,10). This advance of the cords in the overall string system results in the aforementioned parallel guide of the shielding device.
5 Som det også fremgår af fig. 2 så vil der ved enhver retningsændring af snore ne optræde større eller mindre friktionskræfter pga. snorenes berøring med de to stokke (2,3). I en almindelig betjeningssituation, hvor bundstokken (3) bevæges nedad, vil man som følge af de optrædende friktionskræfter, indledningsvist skulle anvendes en kraft der er større end friktionskraften. Denne effekt vil af brugeren opfattes 10 som en bremseeffekt, der er størst i starten af bevægelsen. Samtidig sker der en forøgelse af snorspændingen imellem bundstokken (3) og de øvre fastgørelseselementer (7,8), medens snorene imellem bundstokken (3) og de nederste fastgørelseselementer (9,10) vil slækkes, hvilket af brugeren opfattes som om den nævnte bremseeffekt aftager, så gardinet let kan bevæges nedad.5 As can also be seen from FIG. 2, in any direction change of the cords, greater or lesser frictional forces will occur due to the contact of the cords with the two rods (2,3). In a normal operating situation, where the base (3) is moved downwards, a force greater than the frictional force will initially have to be used because of the frictional forces. This effect will be perceived by the user as a braking effect which is greatest at the start of the movement. At the same time, there is an increase in the cord tension between the base (3) and the upper fastening elements (7,8), while the cords between the base (3) and the lower fastening elements (9,10) will be relaxed, as perceived by the user as if the said braking effect decreases so that the curtain can be easily moved downwards.
15 Som det tydeligt er vist på fig. 3 og 4 kan afskærmningsindretningen i over ensstemmelse med opfindelsen være forsynet med en særlig bremseindretning (12), der til illustrationsformål er udformet som et i bundstokken (3) monteret og på sno-rarrangementeme (5,6) variabelt virkende friktionselement (20-25), med hvilket man kan kompensere for en manglende snorspænding, der eksempelvis kan være opstået 20 som følge af produktionstolerancer, dvs. hvor de enkelte snorarrangementer (5,6) ikke har den samme længde eller som følge af almindelig slidtage af snorarrangementeme (5,6) ved disse almindelige brug.15 As is clearly shown in FIG. 3 and 4, the shielding device in accordance with the invention may be provided with a special braking device (12) which is illustratively designed as a friction element (20-25) which is mounted in the base (3) and mounted on the string arrangements (5,6). ), by which one can compensate for a lack of string tension, which may, for example, have arisen 20 as a result of production tolerances, ie. wherein the individual string arrangements (5,6) do not have the same length or as a result of ordinary wear of the string arrangements (5,6) in these ordinary uses.
Friktionselementet (20-25) er således anbragt i bundstokken (3) som en separat udtagelig enhed, men kunne principielt være en med bundstokken fast eller inte-25 greret enhed. Friktionselementet (20-25) udgøres i denne udførelse af en fjedertråd, der er bukket ud i et stykke til dannelse af en i det væsentlige lukket geometri med en ydre del (20) og en indre del (21), som er forbundet til hinanden gennem et fælles stykke (22), der udgør en fælles omdrejningsakse for de to dele (20,21). De to dele (20,21) kan således bevæge sig i forhold til hinanden, idet elementet (20-25) i sin ud-30 gangstilstand har de to deles (20,21) normalplaner liggende med en vinkel på omkring 45° imellem sig. Andre vinkler kan naturligvis komme på tale, men først og fremmest bestemmes eller fastlægges viklen i udgangstilstanden på basis af oplysninger omkring de mulige pruduktionstolerancer for snorarrangementeme (5,6), idet man ved at træk- 6 DK 174572 B1 ke snorearrangementeme (5,6) igennem friktionselementet (20-25) på den viste måde kan kompensere for de optrædende tolerancer gennem et korrekt valg af åbningsviklen.Thus, the friction element (20-25) is arranged in the base (3) as a separate removable unit, but could in principle be one with the base fixed or integrated. In this embodiment, the friction element (20-25) is constituted by a spring wire which is extended in one piece to form a substantially closed geometry with an outer part (20) and an inner part (21) connected to each other. through a common piece (22) forming a common axis of rotation for the two parts (20, 21). Thus, the two parts (20,21) can move relative to each other, the element (20-25) in its initial state having the normal planes of the two parts (20,21) at an angle of about 45 ° between them . Other angles can of course be considered, but first and foremost the winding in the initial state is determined or determined on the basis of information about the possible production tolerances for the string arrangements (5,6), by drawing the string arrangements (5,6). ) through the friction element (20-25) in the manner shown can compensate for the tolerances occurring through proper selection of the opening winding.
Det forhold at friktionselementets (20-25) to indbyrdes forbundne dele (20,21) 5 bevæges i forhold til hinanden i afhængighed af snorarrangementemes snorspænding medfører som nævnt i eksemplet ovenfor, at når man i en almindelig betjeningssituation, ønsker at bevæge bundstokken (3) nedad, så vil man som følge af de optrædende friktionskræfter, indledningsvist skulle anvende en kraft der er større end friktions-kraften. Denne effekt vil af brugeren opfattes som en bremseeffekt, der er størst i 10 starten af bevægelsen. Samtidig sker der en forøgelse af snorspændingen imellem bundstokken (3) og de øvre fastgørelseselementer (7,8), medens snorene imellem bundstokken (3) og de nederste fastgørelseselementer (9,10) vil slækkes, hvilket af brugeren opleves som om den nævnte bremseeffekt aftager, så gardinet let kan bevæges nedad. Denne oplevelse af effekten forstærkes ved at anvende friktionsindretnin-15 gen (20-25) ifølge opfindelsen, idet dennes to dele (20,21), som har et antal friktions-områder, der omfatter det fælles benstykke (22), samt yderligere et antal forbindelsesben (23-25), vil blive klemt sammen som en følge af den øgede snorspænding. Herved mindskes åbningsvinklen mellem de to dele (20,21), hvilket medfører en reduktion af friktionen mellem snorarrangementerne (5,6) og de enkelte forbindelsesben (22-25), 20 pga. at omslyngningsvinkleme bliver mindre end i udgangstilstanden. Hele snorsystemets kraftmæssige ligevægt kan i øvrigt beregnes efter formlen: S' = S" · εαμ hvor S' og S" udgør kræfterne henholdsvis før og efter passagen af forbindelsesbenene (22-25), μ er friktionen mellem det enkelte ben og snorarrangementet, og α er om-25 slyngningsviklen.The fact that the two interconnected portions (20, 21) 5 of the friction element (20-25) are moved relative to each other in dependence on the string tension of the string arrangements, as mentioned in the example above, means that when in a normal operating situation, one wants to move the base (3). ) downwards, as a result of the frictional forces occurring, initially a force greater than the frictional force would have to be applied. This effect will be perceived by the user as a braking effect which is greatest at the start of the movement. At the same time, there is an increase in the cord tension between the base (3) and the upper fasteners (7,8), while the cords between the bottom (3) and the lower fasteners (9,10) will be attenuated, as experienced by the user as if the said braking effect decreases so that the curtain can be easily moved downwards. This experience of the effect is enhanced by using the friction device (20-25) of the invention, its two parts (20, 21) having a plurality of friction areas comprising the common leg piece (22) as well as a further one. number of connecting legs (23-25), will be squeezed as a result of the increased string tension. This reduces the opening angle between the two parts (20, 21), which results in a reduction of the friction between the string arrangements (5,6) and the individual connecting legs (22-25), 20 because the wrapping angles become smaller than in the initial state. Moreover, the force equilibrium of the entire string system can be calculated according to the formula: S '= S "· εαμ where S' and S" constitute the forces before and after the passage of the connecting legs (22-25), μ is the friction between the individual leg and the string arrangement, and α is the coil winding.
Selvom der således kan opnås en reduceret bremseeffekt for afskærmningen, så forbliver snorarrangementeme (5,6) i en forspændt tilstand med den virkning, at dugen (4) altid fremstår helt udspændt og afskærmningen ikke af sig selv begynder at bevæge sig op eller ned. Samtidig giver anvendelsen af det på snorarrangementeme 30 (5,6) variabelt virkende friktionselement (20-25) som nævnt en vis bremsende effekt på snorene, hvilket betyder at betjeningskomforten øges, idet betjeningskraften kan nedsættes samtidig med at det stadig er muligt at parkere afskærmningen i en vilkårlig 7 DK 174572 B1 position uafhængigt af om den er anbragt i en fast vinduesåbning eller en bevægelig vinduesramme.Thus, while a reduced braking effect can be achieved for the shielding, the leash arrangements (5,6) remain in a biased condition with the effect that the tablecloth (4) always appears fully tensioned and the shielding does not start moving up or down by itself. At the same time, as mentioned, the use of the friction element (20-25) on the lanyard arrangements 30 (5,6) provides a certain braking effect on the leashes, which means that the operating comfort is increased, since the operating force can be reduced while still allowing the shielding to be parked. in any position regardless of whether it is located in a fixed window opening or a movable window frame.
I en ikke vist udførelsesform for en afskræmningsindretning i overensstemmelse med opfindelsen, så kunne den omtalte ophængningsstok være monteret foroven i 5 vinduesåbningen eksempelvis på og mellem de omtalte fastgørelseselementer, og således udgøre et mere almindeligt gardin eventuelt dækket af en frontplade.In a not shown embodiment of a screening device according to the invention, the said hanging cane could be mounted at the top of the window opening, for example, on and between the said fastening elements, thus constituting a more ordinary curtain possibly covered by a faceplate.
Som det fremgår af fig. 5 så anvendes i en anden særlig udførelsesform for opfindelsen to separate afskærmningsarrangementer (1,100) med hver sine snorarrangementer til parallelføring af de enkelte duge, hvor den ene afskærmning (100) ek-10 sempelvis kan udgøres af det tidligere nævnte fjederforspændte rullegardin (104) anbragt øverst i en vinduesåbning, hvor dette rullegardins bundstok (103) kobles sammen med en anden afskærmnings (1) ophængningsstok (2), hvilken anden afskærmning (1) kan være af den type nævnt indledningsvist med en ophængningsstok (2) og en til denne forbundet dug (4), hvilken dug ved dugens nedre frie ende er forbundet 15 med en bundstok (3). Selve bremseindretningen (12) med det nævnte variabelt virkende friktionselement (20-25) kan i sagens natur være anbragt enten i begge bundstokke (3,103) eller kun i den ene. Selve funktionen af bremseindretningen følger den ovenfor beskrevne forklaring.As shown in FIG. 5, in another particular embodiment of the invention, two separate shielding arrangements (1,100) are used, each with its own string arrangements for parallel guiding of the individual tabs, one of which the shielding (100) may for example consist of the previously mentioned spring-biased roller curtain (104) arranged at the top of a window opening where the bottom bar (103) of this roller blind is coupled to a second bar (1) hanging bar (2), which second bar (1) may be of the type mentioned initially with a bar (2) and one connected thereto a tablecloth (4), said tablecloth at the lower free end of the tablecloth is connected to a base (3). The braking device itself (12) with said variable acting friction element (20-25) can, by its nature, be disposed either in both bottom rods (3,103) or only in one. The function of the braking device itself follows the explanation described above.
Opfindelsen skal ikke her begrænses til anvendelse i den viste og beskrevne 20 udførelsesform men kan anvendes i forbindelse med alle former for vinduesåbninger eller vinduer i form af facadevinduer, ovenlysvinduer m.m.The invention is not to be limited here to use in the embodiment shown and described, but can be used in connection with all kinds of window openings or windows in the form of facade windows, skylights etc.
Afskærmningsindretningen ifølge opfindelsen kan således også anvendes sammen med en anden ikke vist udformet afskærmningstype i form af en foldet eller plisseret dug med en kassette eller et magasin anbragt øverst i vinduesåbningen til oplagring af du-25 gen.Thus, the shielding device according to the invention can also be used with another type of shielding not shown, in the form of a folded or pleated tablecloth with a cassette or magazine located at the top of the window opening for storage of the tablecloth.
På samme måde kan en anden ikke vist mulig udformning for snorarrangementet være, at det er udformet som et separat løst arrangement omfattende to snore med fastgørelseselementer til montering i vinduesåbningen, en montagestok til parallelføring, hvori kan være indbygget en bremseindretning i overensstemmelse med op-30 findelsen, hvor montagestokken samtidig kan fungere som sammenkoblingsindretning med afskærmningens bundstok, hhv. den ene afskærmnings bundstok og den anden afskærmnings ophængningsstok i tilfælde af, at der anvendes to afskærmningerSimilarly, another possible embodiment of the leash arrangement may not be shown to be configured as a separate loose arrangement comprising two leashes with fasteners for mounting in the window opening, a parallel mounting rod in which may be incorporated a braking device in accordance with the arrangement. the finding in which the mounting stick can simultaneously function as an interlocking device with the base of the shield, respectively. the one guard base and the other guard suspension in case two guards are used
En anden mulighed er at koble et elektrisk nedhalertræk sammen med et rulle- g DK 174572 B1 gardins bundstok og det nævnte snorarrangement.Another option is to connect an electric download puller with a roller base and the mentioned string arrangement.
Afskærmningsindretningen ifølge opfindelsen kan med fordel anvendes i forbindelse med lystætte afskærmningstyper, dvs. afskærmninger, der udover en dug og et snorarrangement eksempelvis omfatter afdækningselementer til anbringelse langs 5 vinduesåbningens kanter. Lystætningen kan her sikres gennem afskærmningsindretningen ifølge opfindelsen med et snorarrangement omfattende en bund- eller ophængningsstok med en mod vinduesåbningens bund lystætnende flig, flange eller pakning.The shielding device according to the invention can advantageously be used in connection with light-proof shielding types, i.e. guards which, in addition to a tablecloth and a string arrangement, include, for example, cover elements for placement along the edges of the window opening. Here, the light seal can be secured through the shielding device according to the invention with a string arrangement comprising a base or suspension rod with a light-sealing tab, flange or gasket which is light-resistant to the bottom of the window opening.
