Et jalousi af denne art er kendt fra hollandsk patentansøgning nr. 7307075.A jealousy of this kind is known from Dutch Patent Application No. 7307075.
I det allerede kendte jalousi er der anbragt endestop i 20 begge ender på den øvre skinne, idet et af endestoppene er forsynet med et hul til gennemføring af et antal snore. I den praktisk anvendte udførelsesform er snorene, der af og til beløber sig til ni stykker, forbundet til en enkelt snor, hvorved jalousiet kan trækkes op eller ned. Til 25 fastgørelse af snoren anvendes et knæled, der er monteret på vinduesrammen.In the prior art shutter, end stops are provided at both ends of the upper rail, one of the end stops being provided with a hole for carrying a plurality of cords. In the practically used embodiment, the ropes, sometimes amounting to nine pieces, are connected to a single string, whereby the jealousy can be pulled up or down. To fasten the string, use a knee joint that is mounted on the window frame.
Der er således et behov for en låsemekanisme, der automatisk låser snorene, når der ikke bliver trukket i dem.Thus, there is a need for a locking mechanism that automatically locks the cords when they are not pulled.

Sådanne automatiske låsemekanismer er kendt fra persienner med vippende lameller. Disse persienner har en meget kraftig øvre skinne, hvor låsemekanismen kan indbygges i skinnen eller fastgøres på ydersiden, hvilket er kendt fra USSuch automatic locking mechanisms are known from tilting blinds. These blinds have a very strong upper rail where the locking mechanism can be built into the rail or secured to the outside, which is known from US

2 patentskrift nr. 2.731.111.2 patent 2,731,111.
Monteringen af den kendte låsemekanisme på den øvre spinkle skinne af jalousiet omtalt i hollandsk patentansøgning 5 nr. 7307075 er ikke mulig på grund af pladsmangel.The mounting of the known locking mechanism on the upper flimsy rail of the shutter disclosed in Dutch Patent Application No. 7307075 is not possible due to lack of space.
Hvis man ville fastgøre den kendte låsemekanisme ved hovedenden af den øvre skinne, ville den effektive længde af den øvre skinne blive mindre, hvorved det solblændende ma-10 teriale ikke ville dække hele vinduet.If the known locking mechanism were to be secured to the head end of the upper rail, the effective length of the upper rail would be reduced, whereby the sun-dazzling material would not cover the entire window.
Hvis man ville anbringe den kendte låsemekanisme på bunden af den ene ende af den øvre skinne, ville det solblændende materiale heller ikke dække hele vinduet.Also, if one would place the known locking mechanism on the bottom of one end of the upper rail, the sun-dazzling material would not cover the entire window.
1515
Hvis man ville anbringe den kendte låsemekanisme mod den side, der vender fremad fra den ene ende af den øvre skinne, ville det relativt store hus til låsemekanismen skjule den spinkle øvre skinne.If one would place the known locking mechanism against the side facing forward from one end of the upper rail, the relatively large housing for the locking mechanism would conceal the flimsy upper rail.
20 På denne baggrund har det været formålet med opfindelsen at konstruere en automatisk låsemekanisme, der er så lille, at den kan indbygges i områder ved det ene endestop eller i et lille camoufleret område mod den ydre side af 25 den ene ende på den øvre skinne.In view of the foregoing, it has been the object of the invention to design an automatic locking mechanism so small that it can be built into areas at one end stop or in a small camouflaged area towards the outer side of one end of the upper rail .
Dette formål opnås ved en låsemekanisme af den indledningsvist angivne art, hvilken låsemekanisme ifølge opfindelsen er særegen ved, at låsemekanismen består af en U-30 formet del, der har en flad bund og ben, hvilken U-formede del ved dens ene ende har en tværplade, i hvilken der er lavet en åbning til gennemføring af et antal snore, og en drejelig udløserdel med en drejeaksel nær den øvre ende, hvilken drejeaksel er ført ind i benene på den U-formedeThis object is achieved by a locking mechanism of the type mentioned initially, which locking mechanism according to the invention is peculiar in that the locking mechanism consists of a U-shaped part having a flat bottom and legs, the U-shaped part having one end thereof. transverse plate, in which is provided an aperture for carrying a plurality of cords, and a rotatable release member with a pivot shaft near the upper end, which pivot shaft is inserted into the legs of the U-shaped
DK 157500 BDK 157500 B
3 del nær toppen af benene, idet den drejelige udløserdel i den laveste stilling i det væsentlige udfylder rummet mellem benene og bunden under drejeakslen, og den nedre kant af den bevægelige udløserdel er anbragt i en afstand fra 5 bunden, der er mindre end tykkelsen af snorene, der udfylder rummet mellem bunden og den nedre kant, idet nævnte drejelige udløserdel er belastet af et i lodret retning i tværpladen forskydeligt lejret organ med en plade eller lignende indretning, hvis frie ende kan samvirke med den 10 tilstødende side af den drejelige udløserdel, hvorhos der for snorene i den del af det forskydelige organ, som er lejret i tværpladen, er tilvejebragt en åbning, der i hovedsagen falder sammen med åbningen i tværpladen, hvorved bunden af åbningerne i det mindste delvis hælder i modsat-15 te retninger.3 portion near the top of the legs, the rotatable release member in the lowest position substantially filling the space between the legs and the bottom under the pivot shaft, and the lower edge of the movable release member being spaced from the bottom less than the thickness of the legs. the cords filling the space between the bottom and the lower edge, said rotatable release member being loaded by a vertically displaceable bearing member with a plate or similar device, the free end of which cooperates with the adjacent side of the rotatable release member, wherein, for the cords in the portion of the displaceable member housed in the transverse plate, an aperture is provided which coincides substantially with the aperture in the transverse plate, the bottom of the apertures at least partially inclined in opposite directions.
På grund af de modsatte hældninger i de to åbninger vil en vandret forskydning af snoren mod den ene side bort fra hældningerne i den forskydelige del frigøre denne del, så 20 den ikke tvinger den drejelige del nedad.Due to the opposite slopes of the two openings, a horizontal displacement of the cord towards one side away from the slopes of the slidable portion will release this portion so that it does not force the rotatable portion downward.
Snorene kan passere under den drejelige del og sænke jalousiet. Ved vandret forskydning af snorene i den modsatte retning tvinger snorene den forskydelige del og dermed den 25 drejelige del nedad, så snorene er fastholdt i enhver ønsket position af jalousiet.The cords can pass under the swivel part and lower the shutter. By horizontal displacement of the cords in the opposite direction, the cords force the slidable portion and thus the pivotal portion downwards, so that the cords are held in any desired position of the shutter.
Det vil være indlysende, at låsemekanismen ifølge opfindelsen ikke kun er anvendelig for jalousier med zigzag-30 mønster. Også i forbindelse med persienner kan låsemekanismen anvendes, eller den kan anvendes til andre foldelige eller vindbeskyttede skærme, der kan lukkes eller åbnes ved hjælp af snore.It will be obvious that the locking mechanism according to the invention is not only applicable to zigzag pattern shutters. Also in the case of blinds, the locking mechanism can be used or it can be used for other foldable or wind protected screens which can be closed or opened by means of cords.

4 Låsemekanismen ifølge det ovennævnte US patentskrift nr. 2.731-111 omfatter også en ti-formet delr som har benf mellem hvilke ben et drejeligt legeme, som har en drejeaksel nær dets øvre ende, er lejret. Denne låsemekanisme er i-5 midlertid ikke egnet til anvendelse ved et jalousi eller lignende genstand, som har en yderst spinkel øvre skinne.The locking mechanism of the aforementioned U.S. Patent No. 2,731-111 also includes a ten-shaped member having legs between which legs a rotatable body having a pivot shaft near its upper end is mounted. This locking mechanism is temporarily unsuitable for use with a shutter or similar object having a very thin upper rail.
Opfindelsen vil i det følgende blive nærmere beskrevet under henvisning til tegningen, hvor: 10The invention will now be described in more detail with reference to the accompanying drawings, in which:
Fig. 1 viser en første udførelsesform i perspektiv af en del af en øvre skinne til et zigzag-foldet jalousi med en låsemekanisme ifølge opfindelsen, der er placeret et stykke derfra, 15 fig. 2 viser et snit i låsemekanismen ifølge opfindelsen i låst position set i hjælpekraftens akseretning, 20 fig. 3 viser låsemekanismen ifølge fig. 2 set fra oven, og fig. 4 viser låsemekanismen i fig. 3 set forfra.FIG. 1 is a perspective view of a first embodiment of a portion of an upper rail for a zigzag-folded blind with a locking mechanism according to the invention located a distance therefrom; FIG. 2 is a sectional view of the locking mechanism according to the invention in the locked position seen in the axial direction of the auxiliary force; FIG. 3 shows the locking mechanism of FIG. 2 from above, and FIG. 4 shows the locking mechanism of FIG. 3 from the front.
25 I fig. 1 består den øvre skinne af to dele 1 og 2. Den ydre skinne 1 er en kendt aluminiumsprofil, og den indre skinne 2 er på kendt måde fremstillet af plast. Det solaf-skærmende materiale, der er foldet i zigzag, er angivet ved 3. Den øvre ende af materialet 3 er fastgjort til den 30 indre skinne 2.In FIG. 1, the upper rail consists of two parts 1 and 2. The outer rail 1 is a known aluminum profile and the inner rail 2 is in a known manner made of plastic. The sunscreen material folded in zigzag is indicated by 3. The upper end of the material 3 is attached to the inner rail 2.
Selvom enden af den ydre skinne i fig. 1 er delvis bortskåret, er det klart, at enderne af den ydre skinne 1 og den indre skinne 2 ender i samme plan.Although the end of the outer rail of FIG. 1 partially cut off, it is clear that the ends of the outer rail 1 and the inner rail 2 end in the same plane.

Den på fig. 1 ikke viste første ende er lukket med et plast-endestop, som vist i hollandsk patentansøgning nr. 7307075. Ved den anden ende i den kendte konstruktion, 5 hvilken anden ende svarer til den i fig. 1 viste ende, anvendes et plast-endestop, der har et hul til snorene 4.The FIG. 1, the first end not shown is closed with a plastic end stop, as shown in Dutch patent application No. 7307075. At the other end of the known construction 5, the second end corresponds to the one in fig. 1, a plastic end stop having a hole for the cords 4 is used.
Låsemekanismen i henhold til opfindelsen erstatter det kendte endestop med en U-formet del med en bund 5 og op-10 retstående vægge 6. Både bunden 5 og væggene 6 er flade og står vinkelret på hinanden. På den bort fra skinnerne 1, 2 vendende endekant af bunden er der anbragt en tværplade 7, i hvilken der er en åbning 8 til snorene 4.The locking mechanism according to the invention replaces the known end stop with a U-shaped part with a bottom 5 and upright walls 6. Both the bottom 5 and the walls 6 are flat and are perpendicular to each other. A transverse plate 7 is arranged on the end edge of the rails 1, 2 of the bottom, in which there is an opening 8 for the cords 4.
15 Som det tydeligst ses på fig. 2 og 3, er der anbragt en drejelig udløserdel 9 mellem benene 6 ved deres øvre ende. Dette kan for eksempel gøres ved hjælp af en tynd aksel 10, der er indsat gennem huller i benene 6 og gennem et hul i udløserdelen 9. I tværgående retning passer udløser-20 delen 9 mellem benene 6 og kan svinges frit i forhold til disse. Den nedre kant af udløserdelen 9 er tæt beliggende til oversiden af bunden 5. Afstanden er mindre end diameteren af snorene 4, som låsemekanismen skal påvirke. Dette betyder, at udløserdelen hælder let i forhold til lodret 25 plan, når snorene 4 ligger på den øvre side af bunden 5.15 As can be seen most clearly in FIG. 2 and 3, a rotatable release member 9 is disposed between the legs 6 at their upper end. This can be done, for example, by means of a thin shaft 10 inserted through holes in the legs 6 and through a hole in the trigger part 9. In transverse direction, the trigger part 9 fits between the legs 6 and can be pivoted freely in relation thereto. The lower edge of the release member 9 is located close to the upper side of the bottom 5. The distance is less than the diameter of the cords 4 which the locking mechanism is to affect. This means that the trigger portion slopes slightly relative to the vertical plane when the cords 4 lie on the upper side of the bottom 5.
Det vil være klart, at udløserdelen 9 vil prøve at indtage en lodret position på grund af dens egen vægt, således at endepositionen, når der ligger snore 4, svarer til posi-30 tionen vist i fig. 2. For at tvinge bevægelsen ind i nævnte endeposition er der indrettet et i lodret retning forskydeligt organ 14. Organet 14 består af en rektangulær lodret del 14a og en rektangulær vandret plade 14b vinkelret på hinanden.It will be appreciated that the trigger portion 9 will attempt to assume a vertical position due to its own weight, so that the end position, when there is string 4, corresponds to the position shown in FIG. 2. In order to force the movement into said end position, a member 14 is displaceable in a vertical direction. The member 14 consists of a rectangular vertical part 14a and a rectangular horizontal plate 14b perpendicular to each other.

Organet 14 er fortrinsvis fremstillet som én enhed i rustfast stål.The member 14 is preferably manufactured as one unit in stainless steel.
5 Den lodrette del 14a er giideligt anbragt i en not 15 i den tykke tværplade 7.5 The vertical part 14a is neatly placed in a groove 15 in the thick transverse plate 7.
I fig. 2 ses, at når organet 14 bevæges nedad, vil den frie ende af pladen 14b tvinge den drejelige udløserdel 9 10 nedad, mens det vil ses, at når organet 14 bevæges opad, vil den frie ende af pladen 14b frigøres fra samvirket med den drejelige udløserdel.In FIG. 2, it will be seen that as the member 14 moves downwardly, the free end of the plate 14b will force the pivotal release member 910 downwardly, while it will be seen that when the member 14 is moved upwardly, the free end of the plate 14b will be released from the engagement with the pivotal member. tumbler.
Disse bevægelser frembringes ved at bevæge snorene i åb-15 ningen 8 i tværpladen 7 til højre, henholdsvis til venstre.These movements are produced by moving the cords in the opening 8 of the transverse plate 7 to the right and left, respectively.
For at gøre dette muligt er der i delen 14a af organet 14 lavet en åbning, hvor snorene 4 kan føres igennem. Denne 20 åbning svarer helt til åbningen 8 i tværpladen 7 med en bunddel 8a, der er bøjet opad til venstre, men åbningen i delen 14a er drejet 180° i forhold til åbningen 8.To make this possible, an opening is made in the part 14a of the means 14 through which the cords 4 can be passed. This opening corresponds completely to the opening 8 of the transverse plate 7 with a bottom portion 8a bent upward to the left, but the opening in the portion 14a is rotated 180 ° relative to the opening 8.
Dette betyder, at bunddelen 8b af åbningen i delen 14a er 25 bøjet opad til højre.This means that the bottom part 8b of the opening in the part 14a is bent upwards to the right.
I ventepositionen er snorene 4 beliggende mellem hældningerne 8a og 8b. Når snorene i fig. 4 er bevæget til venstre, presser de ikke længere på hældningen 8b af organet 30 14, som derved er gjort fri.In the waiting position, the cords 4 are located between the slopes 8a and 8b. When the cords of FIG. 4 is moved to the left, they no longer press the inclination 8b of the member 30 14, which is thereby released.
Når snorene 4 bevæges op langs hældningen 8a, svinges den drejelige udløserdel 9 væk fra snorene, det vil sige, at jalousiet kan sænkes.As the cords 4 are moved up the slope 8a, the pivotal release member 9 is pivoted away from the cords, i.e., the jealousy can be lowered.
DK 157500 BDK 157500 B
7 Når snorene 4 derefter bevæges til højre i f ig. 4, presser de organet 14 og dermed den drejelige udløserdel 9 nedad.7 When the cords 4 are then moved to the right in FIG. 4, they push the member 14 and thus the rotatable release member 9 down.
5 Den U-formede del 5, 6 og tværpladen 7 kan fabrikeres i en sammenhørende del af plast.5 The U-shaped part 5, 6 and the transverse plate 7 can be manufactured in a cohesive part of plastic.
