Nastavljalna priprava za markize ali roleteAdjustment apparatus for awnings or shutters

Izum zadeva pripravo po uvodnem delu zahtevka 1.The invention relates to the preparation according to the introductory part of claim 1.

Priprave zgoraj omenjene vrste se uporabljajo predvsem pri roletah ali markizah. Pri markizah so, če izvzamemo stikalo, vsi deli razporejeni v cevi (gredi), ki nosi prevleko. Posledica tega je, da je nastavljanje obeh končnih delovnih položajev gredi po eni plati zahtevna operacija, kajti dostop do končnih stikal, razporejenih na cevi ali v njej, pogosto otežujejo pokrivna telesa. Po drugi plati pa je tudi zamenjava končnih stikal, ki se lahko poškodujeta in sta podvrženi obrabi, zamudna. Saj je pri tem cev treba demontirati in staro stikalo zamenjati z novim.The preparations of the aforementioned type are mainly used for shutters or awnings. In the case of awnings, apart from the switch, all the parts are arranged in a tube (shaft) that carries the coating. As a result, adjusting the two end positions of the shaft on one side is a difficult operation because access to the end switches arranged on or in the pipe is often made difficult by the covering bodies. On the other hand, replacing end switches that can be damaged and subject to wear is also time consuming. The hose must be removed and the old switch replaced with a new one.

Izhajajoč iz zgornjega stanja tehnike je izum osnovan na nalogi, pri opisanem stanju zadevo olajšati in zagotoviti, da je zlasti nastavitev končnih delovnih položajev gredi kar se da enostavna.Based on the prior art, the invention is based on the task, in the described condition, to ease the matter and to ensure that, in particular, the adjustment of the end working positions of the shaft is as simple as possible.

Postavljena naloga je po izumu rešena z značilnostmi zahtevka 1.The task according to the invention is solved by the features of claim 1.

Spoznamo, da je izum vsekakor upredmeten tedaj, ko gre za pripravo, s katero se oba končna delovna položaja gredi lahko nastavljata kontinuirno i.s. s pomočjo nastavljalnega organa, ki je razporejen smotrno izven navijalne gredi in zasnovan prednostno v obliki dveh neodvisnih nastavljivih uporov. Snemala, ki se uporabljajo v okviru izuma, so priprave, ki so se že večkrat obnesle in delujejo z zelo visoko natančnostjo, utrpijo zelo majhno obrabo in so nastavljive od zunaj.It is to be appreciated that the invention is in any case intended to be a device by which the two end working positions of the shaft can be adjusted continuously i.s. by means of an adjusting body which is arranged expediently outside the winding shaft and preferably formed in the form of two independent adjustable resistors. The recorders used in the context of the invention are devices that have repeatedly acted and acted with very high precision, suffer very little wear and are adjustable from the outside.

Drugače povedano gre tu za pripravo za brezstopenjsko prestavljanje števila zasukov elektromotorno gnane gredi med dvema končnima delovnima položajema pri denimo markizah, roletah, žaluzijah ali podobnem. Pri tem je naprava, ki izvaja linearne ali vrtilne premike, delovno povezana z analogno delujočim snemalcem poti. Končna delovna položaja sta nastavljiva s pomočjo nastavljalnega organa. Smotrno je priprava priključena na elektroniko, s pomočjo katere je trenutni delovni položaj primerljiv s končnima delovnima položajema.In other words, this is a preparation for continuously adjusting the number of rotations of the electromotor driven shaft between the two final working positions, such as awnings, shutters, blinds or the like. In this case, a device that performs linear or rotary movements is connected to an analogly operated path recorder. The final working positions are adjustable by means of the adjusting body. The preparation is conveniently connected to electronics, which makes the current working position comparable to the final working positions.

Nadaljnje smotrne in prednostne konstrukcijske značilnosti izuma so razvidne iz podzahtevkov.Further advantageous and advantageous structural features of the invention are apparent from the sub-claims.

Če imamo opraviti s pripravo za naprave za zatemnjevanje z nosilno gredjo, je smotrno, da ima priprava z nosilno gredjo sodelujoče vreteno z jahačem, ki je aksialno prestavljiv. Vreteno pri tem lahko poteka vzporedno z nosilno gredjo in je lahko razporejeno v njej. Jahač v okviru te izvedbene oblike izuma sodeluje s snemalcem poti. Da bi pripravo lahko zaščitili pred zunanjimi vplivi, je pri nadaljnji smotrni izvedbi izuma predvideno, da je snemalec poti razporejen v gredi. Slednjič je predvideno, da je shranjevalni in nastavljalni organ električno ali elektromagnetno povezan s snemalcem poti.If we are dealing with the preparation for the beam dimming devices, it is advisable that the beam shaft device has a cooperating spindle with an axially adjustable rider. The spindle may be parallel to the carrier shaft and may be arranged therein. In the context of this embodiment of the invention, the rider cooperates with the track recorder. In order to protect the device from external influences, it is contemplated in a further rational embodiment of the invention that the track recorder is arranged in a shaft. The latter is intended to be electrically or electromagnetically coupled to the recorder and to the track recorder.

Temeljna zamisel izuma je torej ta, da je predlagana priprava razporejena zaščiteno v gredi, pri čemer ona z gredjo sodeluje bodisi neposredno ali posredno preko drugega organa, ki opravlja vrtilno ali linearno gibanje. Ta premikanja gredi se prenašajo na snemalec poti in se spreminjajo glede na položaj jahača, predvsem upora snemalca poti. To spreminjanje poteka zvezno, tako da je zagotovljeno brezstopenjsko nastavljanje obeh končnih delovnih položajev naprave za zatemnjevanje.The basic idea of the invention is therefore that the proposed device is arranged securely in the shaft, whereby it interacts with the shaft either directly or indirectly through another body that performs rotational or linear motion. These shaft movements are transmitted to the track recorder and vary according to the position of the rider, especially the resistance of the track recorder. This modification is continuous, so that the end positions of the dimming device are continuously adjusted.

Izvedben primer izuma je shematično predstavljen v skicah in v nadaljnjem pobliže opisan. Pri tem kaže sl. 1 gred s pripravo, ki je priključena na shranjevalni in nastavljalni organ, v vzdolžnem prerezu, sl. 2 pa prerez po črti Π-II s sl. 1.An exemplary embodiment of the invention is schematically presented in the drawings and described in further detail below. In this respect, FIG. 1 is a longitudinal cross-sectional view of a shaft with a device connected to the storage and adjustment body; FIG. 2 is a cross-section along line Π-II of FIG. 1.

V skicah je predstavljena priprava za zvezno nastavljanje števila vrtljajev elektromotorno gnanih naprav pri napravah za zatemnjevanje, kot so markize, rolete ali žaluzije. Pri tem je npr. linearne ali vrtilne premike izvajajoča naprava 7 naprave za zatemnjevanje delovno zvezana s potenciometrično delujočim snemalcem 20 poti. Končna delovna položaja naprave za zatemnjevanje se določata s pomočjo nastavljalnega organa 14. Naprava 7 ima z nosilno gredjo 1 sodelujoče vreteno 6 z jahačem 8, ki je aksialno prestavljiv. Vreteno 6 je razporejeno vzporedno z nosilno gredjo 1 in v njej. Vidimo, da jahač 8 sodeluje s snemalcem 20 poti. Vsi deli priprave, razen nastavljalnega organa 14, kije pritrjen npr. na steni 19 prostora, so razporejeni v gredi 1. Gred 1 se nahaja npr. v zgornjem območju kakega okna in se razteza praviloma po vsej širini okna. Skoncema je gred 1, ki ni predstavljena v vsej svoji dolžini, uležajena in jo poganja elektromotor 11. Rotor 5 gred 1 neposredno poganja in ima notranje ozobljen zobnik 2, ki je delovno zvezan z zunanje ozobljenim zobnikom 16 vretena 6. Vreteno 6 je uležajeno v obeh ležajnih telesih 4 in je opremljeno z zunanjim navojem, ki sodeluje z napravo 7. Pri zasuku vretena 6 se naprava 7 premakne po sl. 1 v desno oz. levo. Naprava 7 nosi jahač 8, ki je z njo preko vijaka 15 čvrsto povezan. Jahač 8 je voden na uporu 10 snemalca 9 poti. V odvisnosti od relativnega položaja jahača 8 glede na snemalec 9 poti nastavljalni organ 14 meri različen upor. Snemalo 9 ima držalno nogo 13, kije del krajevno fiksnega ohišja 3. Pri nastavljanju obeh končnih delovnih položajev se nastavljalni organ 14, ki hkrati služi kot vklopilno stikalo gredi, vsakokrat vključi tedaj, ko gred 1 doseže svoj vsakokratni končni delovni položaj. Tema obema končnima delovnima položajema ustreza določen upor oz. določena indukcija snemalca poti, ki se shranita. Gledano električno sta nastavljalni organ 14 in v gredi razporejena priprava priključena na skupen tokovni vir 100. Na ta tokovni vir 100 je priključena še (neprikazana) elektronika, ki spreminjajoči se upor snemalca 20 poti primerja z nastavljivimi upori nastavljalnega organa. Nastavljalni organ torej obsega dva drug od drugega neodvisno delujoča upora 50, 51, s katerima se npr. s pomočjo vijača (izvijača) nastavljata oba končna delovna položaja gredi. Elektromotor se vklaplja in izklaplja s pomočjo stikal 52, 53. Če je snemalec 20 poti občutljiv upor, ki svojo velikost spreminja in se določa z delovnim položajem jahača 8, se jahač premika vse dotlej, da upor snemalca poti ustreza nastavljenemu uporu 50 oz. 51. Poskusi so pokazali, da se da pri takih snemalcih poti delati z natančnostjo 100'¹ mm, kar je v območju naprave za zatemnjevanje redko dosežena natančnost, ki je zagotovljena praktično v vsej obratovalni dobi naprave za zatemnjevanje.The drawings illustrate the device for continuously adjusting the speed of electromotor driven devices for dimming devices such as awnings, shutters or blinds. In this case, for example, linear or rotational displacements, the dimming device 7 is connected to the dimming device by a 20-way potentiometrically operated recorder. The final working positions of the dimming device are determined by means of the adjusting body 14. The device 7 has a cooperating spindle 6 with a support shaft 1 with an axle 8 which is axially adjustable. The spindle 6 is arranged parallel to and in the support shaft 1. We see rider 8 interacting with the 20-track cameraman. All parts of the apparatus except the adjusting body 14, which is attached e.g. on wall 19 of the room, are arranged in shaft 1. Shaft 1 is located e.g. in the upper area of any window and as a rule extends the entire width of the window. The skunkema is a shaft 1, which is not represented in its entire length, mounted and driven by an electric motor 11. The rotor 5 shaft 1 is directly driven and has an internally serrated gear 2, which is operatively connected to an external toothed gear 16 of the spindle 6. The spindle 6 is mounted in both bearing bodies 4 and is provided with an external thread that cooperates with the device 7. When the spindle 6 is rotated, the device 7 moves according to FIG. 1 to the right or left. The device 7 carries a rider 8, which is firmly connected to it through the screw 15. Rider 8 is guided by the resistance 10 of the cameraman 9 tracks. Depending on the relative position of the rider 8 with respect to the track recorder 9, the adjusting body 14 measures different resistance. The recorder 9 has a holding leg 13 that is part of a locally fixed housing 3. When adjusting the two end operating positions, the adjusting body 14, which simultaneously serves as the actuating switch of the shaft, is engaged each time the shaft 1 reaches its respective end working position. The subject of both end positions corresponds to a certain resistance or resistance. a certain induction of the track recorder to be saved. Viewed electrically, the adjusting body 14 and the shaft arranged in the shaft are connected to a common current source 100. This (current) electronics is connected to this (non-displayed) electronics, which compares the changing resistance of the recorder 20 paths with the adjustable resistors of the adjusting body. The adjusting body therefore comprises two independently acting resistors 50, 51 with which e.g. with the help of a screwdriver, they adjust the two end positions of the shaft. The electric motor is switched on and off by means of switches 52, 53. If the 20-way recorder is a sensitive resistor that changes its size and is determined by the working position of the rider 8, the rider moves until the resistance of the track recorder corresponds to the set resistance of 50 or. 51. Experiments have shown that such track recorders can be operated with an accuracy of 100 ' ¹ mm, which is rarely achieved in the area of the dimming device, which is practically achievable throughout virtually the lifetime of the dimming device.

Po izkušnjah imajo uporabljeni snemalci poti šele tedaj odstopanja od prvotnih vrednosti, ko so bili vključeni več kot milijonkrat. Tudi tedaj pa vrednosti meritev od prvotnih vrednosti odstopajo le za malo odstotkov, tako da to dejstvo ni pomembno. Če slednjič upoštevamo, da so naprave za zatemnjevanje, za kakršne gre tu, v času njihovega obratovanja vključene manj kot sedem tisočkrat, je na dlani, da predlagana priprava dela praktično brez obrabljanja. Kot posebno prednost izuma naj omenimo dejstvo, da nastavljalna priprava svoje nastavljene vrednosti ohrani tudi pri izpadu toka, npr. pri kratkem stiku ali praznih baterijah, kar pri vsakdanjih pripravah ni slučaj. Pri slednjih je namreč pri izpadu toka treba končna delovna položaja na novo nastaviti.In the experience, the track recorders used only have deviations from their original values when they were included more than a million times. Even then, the measurement values deviate from the original values by only a few percent, so this fact does not matter. Considering the latter, that the dimming devices involved here are less than seven thousand times turned on during their operation, it is palpable that the proposed preparation of the work is practically without wear. One particular advantage of the invention is the fact that the adjustment device retains its setpoint even in the event of a power failure, e.g. in the case of short circuits or empty batteries, which is not the case with daily routine. For the latter, in the event of a power failure, the final working position must be re-adjusted.
