(54) Mekanisme til elektrisk manøv*= rerlng af en persienne.(54) Mechanism for electric maneuver * = change of a blind.

Opfindelsen angår en elektrisk manøvremekanisme af den i krav l's indledning angivne art. Fra tysk brugsmønster nr. 7.201.069 kendes en manøvremekanisme af denne art, hvor de to grænsekontakter og disses aktiveringsorganer er fastgjort på en fra motorhuset adskilt bundplade, på hvilken tillige mekanismen til op- og nedrulning af persiennen og til ændring af persiennelamellernes stilling er monteret. Dette arrangement har den mangel, at motoren og grænsekontakterne skal forbindes med hinanden ved elektriske led-® ninger, der er anbragt i persiennens topliste. Ledningernes mon- Q-) tering i toplisten er på grund af de snævre pladsforhold i denne 00 vanskelig og tager lang tid, hvorved en sådan manøvremekanismes fremstilling fordyres.The invention relates to an electrical maneuvering mechanism of the kind set forth in the preamble of claim 1. From German usage pattern no. 7.201.069 there is known a maneuvering mechanism of this kind, in which the two limit switches and their actuating means are fixed on a base plate separated from the motor housing, on which the mechanism for rolling up and down the blinds and for changing the position of the blinds is mounted. . This arrangement has the disadvantage that the motor and the limit switches must be connected to each other by electrical wires placed in the blinds top strip. The installation of the cables in the top list is difficult due to the narrow space conditions in this 00 and takes a long time, thereby making the manufacture of such a maneuver mechanism expensive.

Også den kendte manøvremekanismes senere montering på en forhåndenværende persienne er praktisk taget ikke mulig, da persiennens viklemekanisme er fastgjort på den bundplade, der bærer grænsekontakterne. Også lander en reparation, ved hvilken viklemekanismen skal udskiftes, er den kendte manøvremekanisme uhensigtsmæssig, fordi man til fjernelse af viklemekanismen fra persiennens topliste sammen med viklemekanismen skal fjerne bundpladen med grænsekontakterne og skal afmontere de elektriske forbindelsesorganer mellem grænsekontakterne og motoren og derefter atter fastgøre forbindelsesledningerne til motoren og kontakterne, hvilket som forklaret i det foregående er meget besværligt og bekosteligt.Also, the later mounting of the known maneuvering mechanism on an existing blind is practically not possible, since the blind's winding mechanism is fixed on the base plate carrying the boundary contacts. Also, a repair in which the winding mechanism needs to be replaced, the known maneuvering mechanism is inconvenient because in order to remove the winding mechanism from the blinds top list, together with the winding mechanism, the base plate with the boundary contacts must be removed and the electrical connection means must be removed between the interconnectors and the interconnectors. the motor and contacts, which as explained above is very cumbersome and expensive.

Opfindelsen tager sigte på at afhjælpe disse mangler, og dette opnås ved hjælp af en elektrisk manøvremekanisme med de i krav l's kendetegnende del angivne ejendommeligheder. Ved disse opnås nemlig den fordel, at motoren og grænsekontakterne samt sidstnævntes mekaniske aktiveringsorganer kan samles i en konstruktionsenhed, hvis indbygning i persiennens topliste enten under persiennens fremstilling eller senere kan gennemføres uden særlige omkostninger, idet især den hidtil nødvendige og besværlige anbringelse af elektriske forbindelsesledninger i toplisten bortfalder. Disse arbejder samt de mekaniske manøvreorganers anbringelse er væsentlig bedre og enklere at gennemføre i den virksomhed, der fremstiller drivmotoren, end i den virksomhed, der fremstiller persiennen, fordi man i førstnævnte virksomhed råder over det hertil nødvendige apparatur og har skolet arbejdskraft. Også i tilfælde af en reparation er det fordelagtigt, at den elektriske del er helt adskilt fra persiennens mekaniske del.The invention aims to remedy these deficiencies and this is achieved by means of an electrical maneuvering mechanism with the characteristics specified in claim 1. This provides the advantage that the motor and the limit switches, as well as the latter's mechanical actuators, can be assembled in a structural unit whose incorporation in the blind's top molding can either be carried out during the blind's manufacture or later at no special cost, in particular the hitherto necessary and cumbersome placement of electrical connection lines in the the top list lapses. These works as well as the arrangement of the mechanical maneuvers are considerably better and easier to carry out in the company that manufactures the drive engine than in the company that manufactures the blinds, because in the former company they have the necessary equipment and have trained workers. It is also advantageous in the case of a repair that the electrical part is completely separate from the mechanical part of the blind.

Endvidere opnås den fordel, at manøvreorganets bolt muliggør en forholdsvis stor forskydningsstrækning for manøvreorganet, hvilket medfører, at der ikke opstår vanskeligheder ved justeringen af grænsekontakten for persiennens øvre endestilling. I modsætning hertil påvirkes kontakten for den øvre endestilling ved den kendte teknik således, at en anslagsdel for vægtstangen krummes elastisk omkring en akse vinkelret på vægtstangens svingningsakse. En deformation af manøvrearmen er derfor kun mulig inden for et lille område, således at manøvreleddets udsving i området for kontaktens skifteknap er meget lille, hvorfor en nøjagtig justering af hver enkelt kontakt er nødvendig.Furthermore, the advantage is obtained that the bolt of the actuator enables a relatively large displacement distance for the actuator, which causes no difficulties in adjusting the limit contact for the upper end position of the blind. In contrast, in the prior art, the contact for the upper end position is actuated such that an abutment portion of the lever is curved elastically about an axis perpendicular to the axis of oscillation of the lever. Therefore, a deformation of the maneuvering arm is only possible within a small area, so that the fluctuation of the maneuvering link in the area of the switch's knob is very small, therefore an accurate adjustment of each contact is necessary.

3 U48943 U4894

En yderligere fordel ved opfindelsen er, at manøvreleddene for begge grænsekontakter er kombineret i et enkelt manøvreled, idet bolten tjener som svingningsakse for manøvreleddet for kontakten til den nedre grænsestilling, og at det enkelte manøvreled til trods for sin dobbeltfunktion ikke udsættes for mekanisk deformation, som det er tilfældet ved den kendte teknik.A further advantage of the invention is that the maneuvering joints for both boundary contacts are combined into a single maneuvering joint, the bolt serving as the axis of oscillation of the maneuvering joint for the contact to the lower boundary position, and that, despite its dual function, the individual maneuvering joint is not subjected to mechanical deformation which this is the case with the prior art.

Ved det i krav 2 angivne opnås ved enkle midler en overførsel af den kraft, hvormed persiennens manøvrebånd påvirker den uden for motorhuset beliggende vægtstangsarm, til den inden for motorhuset beliggende vægtstangsarm til aktivering af grænsekontakten.In accordance with claim 2, by simple means, a transfer of the force by which the blind maneuvering belt affects the lever arm located outside the motor housing to the lever arm for activating the boundary contact is achieved.

Ved den i det foregående omtalte kendte mekanisme er aktiveringsorganet udformet som en enarmet, om en akse svingelig vægtstang, hvilket medfører, at vægtstangsendens udsving under kontaktens omkobling kun er meget lille i området ved kontaktens manøvreknap.By the known mechanism mentioned above, the actuator is designed as a single-arm, about one axis pivotal lever, which means that the swing end of the lever end during switching of the switch is only very small in the area of the switch's maneuver button.

Ved manøvremekanismen ifølge krav 2 kan man derimod ved passende valg af længdeforholdet mellem den toarmede vægtstangs to vægtstangsarme undgå en sådan reduktion af bevægelseslængden, så at man kan nøjes med et betydeligt mindre udsving af den mod persiennebåndet anliggende vægtstangsarm.By the maneuvering mechanism according to claim 2, on the other hand, by appropriately choosing the length ratio of the two lever arms of the two-arm bar, such a reduction in the length of movement can be avoided, so that a considerably smaller swing of the lever arm lying against the venetian belt can be satisfied.

Endelig opnås ved det i krav 3 angivne en særlig pladsbesparende anbringelse af grænsekontakteme i motorhuset.Finally, the special space-saving arrangement of the boundary contacts in the motor housing is achieved by claim 3.

I det følgende forklares opfindelsen nærmere ved hjælp af tegningen, hvor fig. 1 skematisk viser en udførelsesform for manøvremekanismen ifølge opfindelsen i to funktionsstillinger svarende henholdsvis til oprulning og afrulning af persiennen, fig. 2 et snit efter linien II-II i fig. 1 ved oprullet persienne, og fig. 3 den i fig. 1 viste mekanisme set i retning af pilen III i fig. 1.In the following, the invention is explained in more detail with reference to the drawing, in which fig. 1 schematically shows an embodiment of the maneuvering mechanism according to the invention in two operating positions corresponding respectively to rolling up and unrolling the blind, fig. 2 is a sectional view taken along line II-II of FIG. 1 in the roller blind, and FIG. 3 shows the one shown in FIG. 1 in the direction of arrow III in FIG. First

Til den i fig. 1 viste mekanisme til elektrisk manøvrering af en persienne hører en elektrisk drivmotor 1, der via en aksel 2 driver en mekanisme 3 til opvikling eller afvikling af persiennen, samt en første grænsekontakt 4 til standsning af drivmotoren 1, når persiennen har nået sin øvre endestilling, og en anden grænsekontakt 5 til standsning af drivmotoren, når persiennen er i sin helt afrullede nedre endestilling. Mekanismens dele 1, 4 og 5 udgør en konstruktionsenhed og er anbragt i et fælles hus 6, der er anbragt i en U-formet hovedliste 7 på persiennen. Huset 6 er fremstillet af plast og således indrettet, at fugtighed ikke kan trænge ind i dette. Samtlige elektriske forbindelser mellem grænsekontakterne 4 og 5 og drivmotoren 1 er anbragt inden i huset. Grænsekontakterne 4 og 5 for henholdsvis persiennens øvre og dens nedre endestilling er monteret på lodrette, over for hinanden beliggende indre flader på sidevægge på en mod viklemekanismen 3 vendende forreste del 8 af huset 6 og er drejet 90° indbyrdes således, at en manøvreknap 15 på grænsekontakten 5 for persiennens nedre endestilling kan bevæges i en retning parallelt med drivakselen 2, medens en manøvreknap 19 på grænsekontakten 4 for persiennens øvre endestilling kan bevæges i vertikal retning. De to grænsekontakter 4 og 5 aktiveres af et fælles manøvreorgan 9, fig. 2, med en cylindrisk bolt 10, fig. 1, der er styret i et leje 11 i huset 6rs bundvæg og rager ned gennem en stor udsparing 12 i hovedlisten 7 nedenfor lejet 11. På den inden for husdelen 8 beliggende del af bolten 10 er fastgjort en flad, stangformet arm 13 med en fra dens ene ende lodret opadragende armdel 14, der i den viste stilling aktiverer grænsekontakten 5's manøvreknap 15 til sænkning af persiennen og holder grænsekontakten 5 i dens ene stilling. På bolten 10's nedre ende nedenfor hovedlisten 7 er anbragt en flad, vandret forløbende arm 16, fig. 2, der er fastgjort til et hylster 17, som er skudt op på bolten 10 og kan låses på denne 5 144894 ved hjælp af en skrue. Armene 13 og 16 på bolten 10 danner tilsammen en toarmet vægtstang, der er svingeligt lejret i lejet 11 i huset 6's bundvæg. Vægtstangens nedre arm 16 er under persiennens oprulning eller nedrulning påvirket af fjederen i grænsekontakten 5 og ligger med sin frie ende an mod det ene persiennebånd 18, der holdes strakt under indvirkning af vægten af persiennelamellerne, og som er bestanddel af viklemekanismen 3. Bolten 10 er ikke blot drejeligt lejret i lejet 11, men er også vertikalt forskydelig i dette, idet forskydningsbevægelsens længde svarer til længden af bevægelsesbanen for grænsekontakten 4's manøvreknap 19. I persiennens øvre endestilling ligger den øverste lamel 20 i persiennen an mod en plastkappe 21 på hylstret 17’s nederste ende, hvorved grænsekontakten 4 for persiennens oprulningsbevægelse holdes i sin afbrudte stilling ved, at kontaktens manøvreknap 19 påvirkes af et parti 22 af den toarmede vægtstangs ene arm 13 på den i fig. 2 og 3 viste måde. Det nævnte armparti 22 er T- formet, idet længden af T'ets mod manøvreknappen 19 anliggende tværflig er lidt større end svingningsområdet for afsnittet 22’s frie ende.For the embodiment shown in FIG. 1 for the electric operation of a venetian blind, an electric drive motor 1 which drives via a shaft 2 drives a mechanism 3 for winding or unwinding the venetian blind, and a first limit contact 4 for stopping the driving motor 1 when the venetian blind has reached its upper end position, and another limit switch 5 for stopping the drive motor when the blind is in its fully rolled lower end position. The parts 1, 4 and 5 of the mechanism constitute a structural unit and are arranged in a common housing 6 which is arranged in a U-shaped main strip 7 on the blind. The housing 6 is made of plastic and so arranged that moisture cannot penetrate it. All electrical connections between the limit switches 4 and 5 and the drive motor 1 are arranged within the housing. The limit switches 4 and 5 for the upper and lower end positions of the blind, respectively, are mounted on vertical, opposite inner surfaces of the sidewalls of the front part 8 of the housing 6 facing the winding mechanism 3 and are rotated 90 ° so that a maneuver button 15 of the lower limit position 5 of the blind can be moved in a direction parallel to the drive shaft 2, while a maneuver button 19 of the limit switch 4 for the upper end position of the blind can be moved in a vertical direction. The two limit contacts 4 and 5 are actuated by a common actuator 9, fig. 2, with a cylindrical bolt 10, fig. 1, which is guided in a bearing 11 in the bottom wall of the housing 6 and projects down through a large recess 12 in the main strip 7 below the bearing 11. On the part 10 of the bolt 10 located within the housing part 8 is mounted a flat, rod-shaped arm 13 with a its one end vertical upright arm portion 14 which, in the shown position, activates the limit switch 5's maneuver button 15 for lowering the blind and holds the limit switch 5 in its one position. On the lower end of the bolt 10 below the main strip 7 is arranged a flat, horizontally extending arm 16, fig. 2, which is attached to a sleeve 17 which is bolted onto the bolt 10 and can be locked onto it 5 by means of a screw. The arms 13 and 16 of the bolt 10 together form a two-armed lever pivotally mounted in the bearing 11 in the bottom wall of the housing 6. The lower arm 16 of the barbell, under the roll-up or roll-down of the blinds, is actuated by the spring in the boundary contact 5 and abuts with its free end against one of the venetian blind bands 18 which are held under the influence of the weight of the blinds and which is a component of the winding mechanism 3. The bolt 10 is not only pivotally mounted in the bearing 11, but also vertically displaceable therein, the length of the displacement movement corresponding to the length of the path of movement of the limit switch 4's maneuver button 19. In the upper end position of the blind, the upper slat 20 in the blind lies against a plastic sheath 21 on the bottom of the sheath 17 end, whereby the limit switch 4 of the blind reel movement is held in its disconnected position by the actuator button 19 of the contact being actuated by a portion 22 of one arm 13 of the two-arm lever in the one shown in FIG. 2 and 3. Said arm portion 22 is T-shaped, the length of the T-tab abutting the maneuver button 19 being slightly larger than the pivoting area of the free end of section 22.

Fig. 3 viser den toarmede vægtstang 13, 14, 16 i persiennens nedre endestilling. Vægtstangen bringes i denne stilling, når persiennens nederste lamel 23 kommer til at hvile på for eksempel en i fig. 1 ikke vist vindueskarm, hvorved den horisontale kraft-komposant, hvormed persiennebåndet 18 påvirker vægtstangsarmen 16 og holder vægtstangen trykket mod grænsekontakten 5’s manøvreknap 15 mod virkningen af denne kontakts fjeder, mindskes så meget, at fjedertrykket bliver tilstrækkeligt stort til at svinge vægtstangen.FIG. 3 shows the two-arm bar 13, 14, 16 in the lower end position of the blind. The lever is put in this position when the lower lamella 23 of the blind will rest on, for example, one in FIG. 1 is not shown a window frame, whereby the horizontal force component with which the venetian belt 18 affects the lever arm 16 and keeps the lever pressed against the limit switch 5's maneuver button 15 against the action of the spring of this contact is reduced so much that the spring pressure becomes sufficiently large to swing the lever.
