(54) persienne med .kugleledsophæng for lodrette lameller.(54) Venetian blinds with vertical ball joints.

Den foreliggende opfindelse angår en persienne med kugleledsophæng for lodrette lameller, der hænger ned fra løbevogne, der er forskydelige langs en vandret bæreliste, hvilke løbevogne hver indeholder en drejemekanisme i indgreb med en fælles, gennem alle løbevognene ført og med bærelisten parallel medbringeraksel, ved hjælp af hvilken lamellerne kan drejes om deres lodrette akser, idet medbringerakslen er aksialt fortandet og i hver løbe- ® vogn i indgreb med et udsnit af en i løbevognen lejret tandhjuls-BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball joint suspension blinds for vertical slats suspended from trolleys slidable along a horizontal support rail, each trolley incorporating a pivot mechanism engaging a joint through all of the trolleys and with the carrier rail parallel carrier shaft. of which the slats can be rotated about their vertical axes, the carrier shaft being axially toothed and in each trolley in engagement with a section of a gear mounted in the trolley.

LOLO

r- krans med plan fortanding, der har en fra kransens centrum kort, ^ nedefter vendende aksel, hvilken aksel bærer lamellen.A flat-toothed rim having a short shaft from the center of the rim, downwardly facing, which shaft carries the slat.

I en sædvanlig persienne er ^ løbevognen eksempelvis 9-12 mm lang.? n cf The trolleys must have as little length as possible in the longitudinal direction of the carrier shaft, so that the slats can be pushed close together at one end of the carrier strip. For example, in a conventional blind, the trolley is 9-12 mm long.

143516 2143516 2

Ved at skråtstille tandhjulskransene i løhevognene opnår man, at kransens radius kan være større end løbevognens længde i medbringerakslens længderetning, fordi hjulene på naboløbevogne kan glide delvis ind over hinanden, når løbevognene skydes sammen ved bærelistens ene ende. Samtidig opnås, at det anvendte kransudsnit kan være større end 180°, fordi tænderne frit kan passere under tandakslen i modsat side af indgrebssiden. Større tandhjulskranse betinger en mere robust konstruktion.By tilting the cogwheels in the trolleys, it is obtained that the radius of the crane can be greater than the length of the trolley in the longitudinal direction of the driver axle, because the wheels of neighboring carriages can slide partially over each other when the trolleys are pushed together at one end of the carrier. At the same time, it is achieved that the coronary section used can be greater than 180 ° because the teeth can freely pass under the tooth shaft on the opposite side of the engagement side. Larger cogwheels require a more robust construction.

Især når kransakslen ikke er lodret, skal den naturligvis forbindes med den lodrette lamelaksel ved hjælp af en passende kobling.Especially when the crankshaft is not vertical, it must of course be connected to the vertical slat shaft by a suitable coupling.

Ifølge den foreliggende opfindelse foreslås, at tandhjuls-r kransens aksel i sin nederste frie ende er udformet som eller bærer en kugle med to diametrale, vinkelret på akslen stående tappe, og at den øverste frie ende af lamellen er udformet som eller bærer en rørformet bøsning af eftergivende materiale, hvorved bøsningens væg, der har to diametrale slidser til optagelse af kuglens tappe, foroven afgrænser en opadhvælvet, til kuglen svarende halvkugleskal med en polær åbning, hvis diameter er lidt større end kransakslens diameter.According to the present invention, it is proposed that the sprocket shaft of the wreath at its lower free end is formed as or carries a ball of two diametrically perpendicular to the shaft, and that the upper free end of the slat is formed as or carries a tubular bush. of resilient material, whereby the sleeve wall, which has two diametrical slots for receiving the spigot of the ball, delimits at the top an upward vault corresponding to the sphere with a polar orifice having a polar opening slightly larger than the diameter of the crankshaft.

Ved denne udformning opnås, at koblingen mellem løbevognen og lamellen virker som sikkerhedskobling. Et hårdt træk i lamellen vil nemlig på grund af bøsningsmaterialets eftergivelig-hed medføre, at bøsningens vægge fjedrer fra hinanden. Herved slipper bøsningen sit greb om kuglen på kransakslen, således at løbevognen kan forskydes langs medbringerakslen og/eller tandhjulskransen drejes med medbringerakslen, selv om lamellen bliver stående.In this embodiment, the coupling between the trolley and the slat is achieved as a safety coupling. Namely, because of the resilience of the sleeve material, a hard pull in the slat will cause the sleeve walls to spring apart. In this way, the bushing releases its grip on the ball on the crankshaft, so that the trolley can be displaced along the drive shaft and / or the gear ring is rotated with the drive shaft, even if the slat remains standing.

Opfindelsen skal i det følgende forklares nærmere i forbindelse med tegningen, som i perspektiv viser en løbevogn og en del af medbringerakslen i en persienne ifølge opfindelsen, idet løbevognens enkelte hoveddele er indbyrdes adskilt.The invention will now be explained in more detail in connection with the drawing, which shows in perspective a trolley and part of the carrier shaft in a blind according to the invention, the individual main parts of the trolley being separated from each other.

Den på tegningen viste, aksialt fortandede medbringeraksel 1 er lejret i persiennens løbevogne 2 på en sådan måde, at løbevognene frit kan bevæges aksialt langs akslen.The axially toothed driver shaft 1 shown in the drawing is mounted in the blinds 2 of the blinds in such a way that the trolleys can move freely axially along the shaft.

Medbringerakslen 1 er i indgreb med et kransudsnit på lidt over 180° af en tandhjulskrans 3 med plan fortanding, og hvis aksel i løbevognen 2 er skråtstillet i forhold til den lodrette aksel for en ikke vist persiennelamel.The drive shaft 1 engages with a wreath cut of just over 180 ° of a cogwheel 3 with a flat tooth and whose shaft in the trolley 2 is inclined with respect to the vertical shaft of a blind not shown.

3 143516 I lamellernes udgangsstilling vinkelret på et lodret plan gennem persiennens ikke viste bæreliste, der er parallel med medbringerakslen 1, er medbringerakslen 1 i indgreb midt på kransudsnittet 3, som vist på tegningen, og lamellerne kan fra udgangsstillingen drejes om deres lodrette akser 90° til hver side, ved at medbringerakslen 1 drejes.In the starting position of the slats perpendicular to a vertical plane through the carrier not shown parallel to the carrier shaft 1, the carrier shaft 1 engages in the middle of the wreath section 3, as shown in the drawing, and the slats can be rotated from their initial position by their vertical axes 90 ° to each side by turning the drive shaft 1.

I lamellernes udgangsstilling er kransudsnittets 3 mindste udstrækning, der omtrent er lig med kransens radius, beliggende i medbringerakslen l’s længderetning. På grund af de skråtstillede kransudsnit kan kransradien være noget større end løbevog-nens 1 længde i medbringerakslens længderetning, fordi tandhjulskransene kan glide ind over hinanden, når naboiøbevogne skydes sammen. Kransudsnittene kan altså være ret kraftige og fortan-dingen grov, således at mekanismen bliver meget robust.In the starting position of the slats, the smallest extent of the wreath section 3, which is approximately equal to the radius of the wreath, is located in the longitudinal direction of the drive shaft 1. Due to the inclined wreath sections, the wreath radius may be somewhat larger than the length of the trolley 1 in the longitudinal direction of the driver shaft, because the gear wheels may slide over each other as neighboring carriages are pushed together. Thus, the crown sections can be quite powerful and the teeth rough, so that the mechanism becomes very robust.

Som vist kan tandhjulskransen 3 have stopknaster 4 eller lignende organer, som ved samvirke med flader på løbevognen 2 hindrer, at lamellerne drejes mere end 90° bort fra udgangsstillingen.As shown, the gear ring 3 may have stop lugs 4 or similar means which, when interacting with surfaces of the trolley 2, prevent the slats from turning more than 90 ° away from the starting position.

Den kobling, der er nødvendig mellem løbevognen og lamellen, fordi kransens 3 aksel er skrå, er ifølge opfindelsen udformet på følgende måde.The coupling required between the trolley and the slat because the shaft of the wreath 3 is inclined is according to the invention designed as follows.

Tandhjulskransens 3 aksel bærer forneden en kugle 32 med to diametrale, vinkelret på akslen stående tappe.The shaft of the gear ring 3 carries at the bottom a sphere 32 with two diametrical pins perpendicular to the shaft.

Til den øverste ende af den ikke viste lamelaksel er fast*-gjort en rørformet bøsning 33 af eftergivende materiale såsom plast. Bøsningens væg afgrænser foroven en opadhvælvet halvkugleskal med samme diameter som kuglen 32 og med en polær åbning 34, hvis diameter er lidt større end diameteren af kransens 3 aksel. I bøsningens 33 væg findes endvidere to diametrale ak-siale slidser til optagelse af kuglens 32 tappe.Attached to the upper end of the slat shaft not shown is a tubular sleeve 33 of resilient material such as plastic. The wall of the sleeve defines at the top an upwardly arched hemisphere shell of the same diameter as the ball 32 and with a polar aperture 34, the diameter of which is slightly larger than the diameter of the shaft 3. In addition, in the wall of the sleeve 33 are two diametrical axial slots for receiving the pin 32 of the ball.

På grund af bøsningsmaterialets eftergivenhed kan kuglen 32 presses gennem åbningen 34, og når bøsnings væggene fjedrer til-r bage, fastholdes kuglen under halvkugleskallen.Due to the silliness of the sleeve material, the ball 32 can be pressed through the opening 34 and as the sleeve walls spring back, the ball is held under the hemisphere shell.

Tappene på kuglen virker ved drejning af kransens eller lamellens aksel som medbringert^ppe, men lamellens vægt holder denne lodret uanset kransakslens stilling.The pivots on the ball act on turning the shaft of the wreath or lamella as carried, but the weight of the wafer holds it vertically regardless of the position of the wreath shaft.

Den anviste kobling virker som sikkerhedskobling, idet et hårdt træk i lamellen vil medføre, at bøsningens 33 vægge fjedrer fra hinanden, således at grebet om kuglen 32 slippes, før andre konstruktionsdele overbelastes.The coupling shown acts as a safety coupling, as a hard pull in the slat will cause the walls of the bush 33 to spring apart so that the grip of the ball 32 is released before other structural members are overloaded.
