DK 177259 B1 i RØRAKTUATOR Opfindelsens områdeDK 177259 B1 i RØRAKTUATOR Field of the invention

Den foreliggende opfindelse angår en røraktuator, omfattende en motor, fortrinsvist en cylindrisk motor, hvor motoren er arrangeret i et aflangt motorhus, fortrinsvist et cylindrisk motorhus, hvor røraktuatoren har en inderposition og en yderposition, og hvor røraktuatoren omfatter et gevindrør med et gevind, fortrinsvist et cylindrisk gevindrør, hvor gevindrøret i det mindste har en længde, der er tiisvarende motorhusets længde.The present invention relates to a tube actuator comprising a motor, preferably a cylindrical motor, the motor being arranged in an elongate motor housing, preferably a cylindrical motor housing, wherein the tube actuator has an inner position and an outer position, and wherein the tube actuator comprises a threaded tube with a thread, preferably a cylindrical threaded tube, the threaded tube having at least a length corresponding to the length of the motor housing.

Opfindelsens baggrund I US 2002/11681 Al beskrives en røraktuator til et bordben på hæve/sænkeborde, der omfatter en en motor, der er indbygget i et motorhus i bordbenet. Røraktuatoren omfatter et gevindrør, som er cylindrisk, og som har en længde, der er mindst tilsvarende motorhusets længde. Røraktuatoren har en inderposition, hvor den totale længde af bordbenet svarer til længden af motorhuset samt gevindrøret.Background of the Invention US 2002/11681 A1 discloses a tube actuator for a table leg on raising / lowering tables which comprises a motor built into a motor housing in the table leg. The tube actuator comprises a threaded tube which is cylindrical and has a length at least equal to the length of the motor housing.

I kørestole bliver aktuatorer ofte brugt til at justere forskellige ting såsom sædehøjde m.m. I sådanne applikationer er det et problem, hvis aktuatorerne bliver for store.In wheelchairs, actuators are often used to adjust various things such as seat height, etc. In such applications, it becomes a problem if the actuators become too large.

Ofte er aktuatorens korteste længde, indbygningslængden, vigtig for at designe kørestolene optimalt og kompakt.Often the shortest length of the actuator, the installation length, is important for designing the wheelchairs optimally and compactly.

Opfindelsens formålObject of the invention

Det er opfindelsens formål at angive en kompakt aktuator med så kort en indbygningsiængde som muligt.It is the object of the invention to provide a compact actuator with as short an installation length as possible.

Beskrivelse af opfindelsenDescription of the invention

Dette opnås, ifølge opfindelsen, med en røraktuator af den indledningsvis nævnte type, der er særpræget ved, at gevindrøret er arrangeret således, at gevindrøret i det mindste i inderpositionen i det væsentlige omslutter motorhuset, hvor røraktuatoren yderligere omfatter et indgrebsorgan, hvor indgrebsorganet omfatter midler for indgreb med gevindrøret, hvor indgrebsorgan og gevindrør er bevægelige i forhold tii hinanden.This is achieved, according to the invention, with a tube actuator of the initially mentioned type, characterized in that the threaded tube is arranged such that the threaded tube at least in the inner position substantially encloses the motor housing, the tube actuator further comprising an engaging means, the engaging means comprising means for engagement with the threaded tube, where the engaging member and threaded tube are movable relative to each other.

DK 177259 B1 2 Røraktuatorens inderposition og yderposition er defineret af gevindrøret og indgrebsorganets bevægelighed i forhold til hinanden. Afstanden mellem inderpositionen og yderpositionen definerer aktuatorens vandring.DK 177259 B1 2 The inner position and outer position of the pipe actuator are defined by the threaded pipe and the movement of the engaging member relative to each other. The distance between the inner position and the outer position defines the travel of the actuator.

Gevindrøret omfatter et gevind, typisk i hele gevindrørets længde. Indgrebsorganet omfatter midler, eksempelvis i form afen simpel stift, tap elier lignende, der kan gå i indgreb med gevindrørets gevind, således vil enten gevindrør eller indgrebsorgan bevæge sig i forhold til hinanden, såfremt en af delene roteres af motoren. Inderpositionen vil typisk være, når indgrebsorganet befinder sig ved gevindrørets ene ende, og yderpositionen vii således være, når indgrebsorganet befinder sig ved gevindrørets anden ende.The threaded tube comprises a thread, typically along the entire length of the threaded tube. The engaging means comprises means, for example in the form of simple pins, pins or the like, which can engage with the thread of the threaded tube, thus either threaded tube or engaging member will move relative to each other if one of the parts is rotated by the motor. The inner position will typically be when the engaging means is at one end of the threaded tube, and the outer position will thus be when the engaging means is located at the other end of the threaded tube.

Ved at gevindrøret, i det mindste i inderpositionen, omslutter motorhuset, vil vandringen, såfremt gevindrøret har samme længde som motorhuset, være defineret af motorhusets længde.By the threaded pipe, at least in the inner position, enclosing the motor housing, the travel, if the threaded pipe has the same length as the motor housing, will be defined by the length of the motor housing.

Herved opnås en aktuator, der i sin mest kompakte form har en vandring, der er af samme længde som motoren og derved motorhuset, samtidig med at indbygningslængden også er defineret af længden på motorhuset. Ønskes en længere vandring kan gevindrøret forlænges i forhold til motorhuset. Det vil sige, at aktuatorens størrelse kan defineres som den ønskede vandring, dog begrænset af motorens størrelse. Dette giver meget kompakte og alsidige aktuatorer.Hereby an actuator is obtained which in its most compact form has a travel which is of the same length as the motor and thereby the motor housing, at the same time as the installation length is also defined by the length of the motor housing. If a longer travel is desired, the threaded pipe can be extended in relation to the motor housing. That is, the size of the actuator can be defined as the desired travel, however, limited by the size of the motor. This provides very compact and versatile actuators.

Ifølge en yderligere udførelsesform er røraktuatoren særpræget ved, at gevindrørets gevind er arrangeret på ydersiden af gevindrøret, og hvor gevindrøret er forbundet til motoren således, at gevindrøret er roterbart i forhold til motorhuset.According to a further embodiment, the pipe actuator is characterized in that the thread of the threaded pipe is arranged on the outside of the threaded pipe, and where the threaded pipe is connected to the motor so that the threaded pipe is rotatable relative to the motor housing.

I denne udførelsesform er gevindrøret arrangeret omkring motorhuset således, at gevindet er på ydersiden af gevindrøret. Gevindrøret er forbundet til motoren, typisk via motorakslen, således at gevindrøret kan rotere, når motoren aktiveres.In this embodiment, the threaded tube is arranged around the motor housing so that the thread is on the outside of the threaded tube. The threaded tube is connected to the motor, typically via the motor shaft, so that the threaded tube can rotate when the motor is activated.

Indgrebsorganet vil, når gevind røret roterer, flyttes langs gevindrøret pga. indgrebet med gevindet.When the threaded tube rotates, the engaging means will move along the threaded tube due to the engagement with the thread.

DK 177259 B1 3 Røraktuatoren kan også omfatte en eller flere lejer, som gevindrøret kan dreje omkring for at minimere slid, støj m.m.DK 177259 B1 3 The pipe actuator can also comprise one or more bearings around which the threaded pipe can rotate to minimize wear, noise, etc.

Ifølge en yderligere udførelsesform er røraktuatoren særpræget ved, at indgrebsorganet omfatter et forfæste for fæstnelse tii en bevægelig del.According to a further embodiment, the tube actuator is characterized in that the engaging means comprises a pre-attachment for attachment to a movable part.

Ved at indgrebsorganet omfatter et forfæste, kan indgrebsorganet fæstnes til en bevægelig del. Herved kan den bevægelige del bevæges af indgrebsorganet, når indgrebsorganet flyttes ved at rotere gevindrøret. Forfæstet kan være et gevindhul til modtagelse af en bolt, skrue eller lignende, eller andre velegnede former af fæstningsmidler.By the engaging means comprising a pre-attachment, the engaging means can be attached to a movable part. Hereby the movable part can be moved by the engaging means when the engaging means is moved by rotating the threaded tube. The fastener may be a threaded hole for receiving a bolt, screw or the like, or other suitable forms of fasteners.

Ifølge en yderligere udføreisesform er røraktuatoren særpræget ved, at gevindrørets gevind er arrangeret på indersiden af gevindrøret, og hvor indgrebsorganet er forbundet til motoren, således at indgrebsorganet er roterbart I forhold til motorhuset.According to a further embodiment, the pipe actuator is characterized in that the thread of the threaded pipe is arranged on the inside of the threaded pipe, and where the engaging means is connected to the motor, so that the engaging means is rotatable relative to the motor housing.

I denne udføreisesform er indgrebsorganet forbundet til motoren, typisk via motorakslen, således at indgrebsorganet kan rotere. Gevindrøret er arrangeret omkring motorhuset, med gevindet på indersiden, således at når indgrebsorganet roteres, vil gevindrøret bevæge sig i forhold til indgrebsorganet og derved motorhuset. I inderpositionen vil gevindrøret i det væsentlige omslutte hele motorhuset. Nar motoren aktiveres vil gevindrøret flyttes mod yderpositionen og således væk fra motorhuset.In this embodiment, the engaging means is connected to the motor, typically via the motor shaft, so that the engaging means can rotate. The threaded tube is arranged around the motor housing, with the thread on the inside, so that when the engaging member is rotated, the threaded tube will move relative to the engaging member and thereby the motor housing. In the inner position, the threaded tube will substantially enclose the entire motor housing. When the motor is activated, the threaded pipe will be moved towards the outer position and thus away from the motor housing.

Ifølge en yderligere udføreisesform er røraktuatoren særpræget ved, at gevindrøret på ydersiden omfatter et forfæste for fæstnelse til en bevægelig del. Forfæstet kan arrangeres på et vilkårligt sted i hele gevindrørets længde. Dette giver en lang række muligheder for at kunne tilpasse røraktuatoren til forskellige applikationer.According to a further embodiment, the tube actuator is characterized in that the threaded tube on the outside comprises a pre-attachment for attachment to a movable part. The pre-attachment can be arranged at any place along the entire length of the threaded pipe. This provides a wide range of options to be able to adapt the tube actuator to different applications.

Yderligere vil gevindrøret kunne omfatte et flertal af forfæster, således at en enkelt røraktuator kan bruges i en lang række forskellige applikationer blot ved at bruge forskellige forfæster.Additionally, the threaded tube may comprise a plurality of preamps so that a single tube actuator can be used in a wide variety of applications simply by using different preamps.

Ifølge en yderligere udføreisesform er røraktuatoren særpræget ved, at motorhuset er i forbindelse med et bagfæste for fæstnelse tii en fast mekanisk del.According to a further embodiment, the tube actuator is characterized in that the motor housing is connected to a rear bracket for attachment to a fixed mechanical part.

DK 177259 B1 4DK 177259 B1 4

Ved at være i forbindelse med et bagfæste, kan motorhuset fæstnes til en fast mekanisk del, således at motorhuset ikke kan rotere, og så røraktuatoren er fæstnet sikkert,By being connected to a rear bracket, the motor housing can be fastened to a fixed mechanical part so that the motor housing cannot rotate and so that the pipe actuator is fastened securely,

Ifølge en yderligere udførelsesform er røraktuatoren særpræget ved, at indgrebsorganet er en møtrik, hvor møtrikken omfatter et gevind modsvarende gevindet på gevindrøret.According to a further embodiment, the tube actuator is characterized in that the engaging means is a nut, the nut comprising a thread corresponding to the thread on the threaded tube.

Ved at indgrebsorganet er en møtrik, opnås en solid forbindelse til gevindrørets gevind, og der kan derfor skabes et stort moment, når enten møtrik eller gevindrør roteres.Because the engaging member is a nut, a solid connection to the thread of the threaded tube is obtained, and a large torque can therefore be created when either the nut or the threaded tube is rotated.

Gevindet på møtrikken kan enten være udformet på indersiden, således at møtrikken kan skrues udenom et gevindrør, eller gevindet kan være på ydersiden, således at møtrikken kan skrues ind i et gevindrør.The thread on the nut can either be designed on the inside so that the nut can be screwed around a threaded pipe, or the thread can be on the outside so that the nut can be screwed into a threaded pipe.

Ifølge en yderligere udførelsesform er røraktuatoren særpræget ved, at motoren er en elektromotor.According to a further embodiment, the tube actuator is characterized in that the motor is an electric motor.

Elektromotorer er at foretrække i mange situationer, eksempelvis i kørestole, da der oftest allerede er elektricitet ti! rådighed. Elektromotorer har yderligere den fordel, at de er billige og kan fås i små kompakte størrelser.Electric motors are preferable in many situations, for example in wheelchairs, as there is usually already ten electricity! availability. Electric motors have the further advantage of being inexpensive and available in small compact sizes.

Røraktuatoren er dog ikke begrænset til brug i forbindelse med en elektromotor.However, the tube actuator is not limited to use with an electric motor.

Hydrauliske, pneumatiske, eller andre former for motorer kan også anvendes.Hydraulic, pneumatic, or other types of motors can also be used.
