Description
Foreliggende oppfinnelse angår en spak som er anordnet på et parti av en aksel som er vesentlig utformet, som et rotasjonslegeme og bestående av en arm og en med denne forbundet bøyleformet klemring som griper omkring nevnte parti av akselen, idet spaken er innrettet for trinnvis rotasjon av akselen ved hjelp av armens svinging frem og tilbake under klemringens medbringing av akselen i den ene dreieretningen og frigivelse i den andre dreieretningen. The present invention relates to a lever which is arranged on a part of an axle which is essentially designed as a body of rotation and consisting of an arm and a hoop-shaped clamping ring connected to it which grips around said part of the axle, the lever being arranged for step-by-step rotation of the shaft by means of the swinging of the arm back and forth during the clamping ring entrainment of the shaft in one direction of rotation and release in the other direction of rotation.
Oppfinnelsen bygger på det prinsipp at en klemring påvirkes til å .spenne rundt et sylindrisk legeme hvorved normalkreftene blir så store at, når klemringen utsettes for en dreiende kraft omkring det sylindriske legemets senterlinje, det oppstår en friksjonslåsing mellom klemringen og det sylindriske legemet. Derved medbringes det sylindriske legemet med den dreiende.bevegelsen i ønsket retning. Ved frigang, dvs. når det sylindriske legemet glir inn i klemringen og så-ledes kan sies å være stillestående i forhold til klemringen, føres klemringen i motsatt retning. I denne retningen er det ingen spennkraft omkring det sylindriske legemet. The invention is based on the principle that a clamping ring is influenced to span around a cylindrical body whereby the normal forces become so great that, when the clamping ring is subjected to a rotating force around the cylindrical body's center line, a friction lock occurs between the clamping ring and the cylindrical body. Thereby, the cylindrical body is brought along with the rotating movement in the desired direction. On release, i.e. when the cylindrical body slides into the clamping ring and can thus be said to be stationary in relation to the clamping ring, the clamping ring is moved in the opposite direction. In this direction, there is no tension force around the cylindrical body.
Oppfinnelsen skal i det følgende forklares nærmere under henvisning til tegningen som viser .en foretrukket ut-førelsesform for spaken ifølge oppfinnelsen. In the following, the invention will be explained in more detail with reference to the drawing which shows a preferred embodiment of the lever according to the invention.
Et vesentlig sylindrisk legeme B omsluttes på den største delen av sin omkrets av en klemring 1 hvis oppgave er, når skaftet 2 dreies mot urviserretningen omkring leddet 3, og overfører en klemkraft over kontaktpunktet A til legemet B som bringes til å rotere omkring sitt sentrum når friksjonslåsing mellom klemringen 1 og legemet B er oppnådd. Klemringen 1 kan være utformet i ett stykke, eller fortrinnsvis være oppbygd av A substantially cylindrical body B is enclosed on the largest part of its circumference by a clamping ring 1 whose task is, when the shaft 2 is turned anti-clockwise around the joint 3, and transmits a clamping force over the contact point A to the body B which is caused to rotate about its center when friction locking between clamping ring 1 and body B is achieved. The clamping ring 1 can be designed in one piece, or preferably be made up of
to eller flere elementer.two or more elements.
I det tilfellet at klemringen består av flere elementer tjener hullene C-som sete for pinner eller lignende for om nødvendig å koordinere elementene til hverandre. Dette eliminerer negative varmebehandlingseffekter og letter hånd-teringen i produksjonen. In the event that the clamping ring consists of several elements, the holes C serve as seats for pins or the like to coordinate the elements to each other if necessary. This eliminates negative heat treatment effects and facilitates handling in production.
Kontaktpunktet A mellom en i skaftet 2 inngående flate og en i klemringen 1 konveks del, kan alternativt utformes med en i skaftet 2 innovergående preging eller en i skaftet 2 inndrevet sylindrisk pinne eller på annen måte, for å oppnå The contact point A between a surface included in the shaft 2 and a convex part in the clamping ring 1 can alternatively be designed with an inward embossing in the shaft 2 or a cylindrical pin driven into the shaft 2 or in some other way, to achieve
et slipp slik at skaftet 2 dg klemringen 1 ikke berører hverandre i noe annet punkt enn det tilsiktede. a release so that the shaft 2 and the clamping ring 1 do not touch each other at any point other than the intended one.
Skaftet 2 utgjør en hevarm over leddet 3 for det utøvde dreiemomentet på legemet B. The shaft 2 constitutes a lifting arm above the joint 3 for the exerted torque on the body B.
Klemringens hevarm D er innstukket i skaftets 2 nedre, åpne del, der klemringen 1 er leddet med leddet 3 som er aksielt låst av krympeslangen 5 som samtidig tjener som flatebeskyttelse og dekor. Skaftet 2 kan med fordel utgjøres av et rør. Leddet 3 kan alternativt låses aksielt ved nagling, inndriving eller på annen måte, eller erstattes av en skruefor-bindelse. Fjæren 4 har som oppgave å gi en nødvendig initialkraft i kontaktpunktet A for å overvinne treghet i systemet, samt for å sikre en minimumsfriksjon mellom klemringen 1 og legemet B for friksjonslåsing når skaftet 2 aktiveres. Fjærens 4 plassering kan varieres innen rammen for at den skal gi en initialkraft rettet slik at klemringen 1 påvirkes for å spenne rundt legemet B. Alternativt kan klemringen 1 være utført slik at den er forspent i montert stilling på legemet B og'således selv besørger den nødvendige initialkraften, idet fjæren h kan utgå. For frigang dreies skaftet 2 med urviserretningen omkring leddet 3, idet kontaktflatene i punktet A atskilles, samtidig som fjæren 4 trykkes sammen helt eller delvis, avhengig av hva som inntrer først - kraftjevnvekt mellom skaftet 2 og fjæren 4 eller mellom skaftet 2 og klemringens lengste hevarm D. Når det ikke virker noen spennende kraft på klemringen 1, glir den på legemet B når kraftjevnvekt er inntrådt i systemet. The clamping ring's lifting arm D is inserted into the lower, open part of the shaft 2, where the clamping ring 1 is connected to the joint 3 which is axially locked by the shrink tube 5 which simultaneously serves as surface protection and decoration. The shaft 2 can advantageously consist of a tube. The joint 3 can alternatively be locked axially by riveting, driving in or in another way, or replaced by a screw connection. The spring 4 has the task of providing a necessary initial force at the contact point A to overcome inertia in the system, as well as to ensure a minimum friction between the clamping ring 1 and the body B for friction locking when the shaft 2 is activated. The position of the spring 4 can be varied within the frame in order for it to provide an initial force directed so that the clamping ring 1 is influenced to clamp around the body B. Alternatively, the clamping ring 1 can be designed so that it is pre-tensioned in the mounted position on the body B and thus provides itself necessary initial force, as the spring h can be omitted. To release, the shaft 2 is turned clockwise around joint 3, the contact surfaces at point A being separated, while the spring 4 is pressed together fully or partially, depending on which occurs first - force equilibrium between the shaft 2 and the spring 4 or between the shaft 2 and the longest lever of the clamping ring D. When there is no exciting force acting on clamping ring 1, it slides on body B when force equilibrium is reached in the system.
Knappen 6 tjener som håndtak og kan naturligvis erstattes med andre typer håndtak. The button 6 serves as a handle and can of course be replaced with other types of handles.
Dersom skaftet 2 utgjøres av et standardrør, kan det vise seg- nødvendig å eliminere den klaring som nødvendigvis må være mellom klemringens 1 tykkelse og rørets innvendige mål på grunn av de forholdsvis store rørtoleransene. Dette kan ut-føres ved en eller flere nedpreginger av røret 2 etter at montering av klemringen 1 er foretatt. Nedpregning kan ut-føres alternativt på den ene eller på begge rørsidene. Elimi-neringen av ikke ønskelig klaring mellom skaftet 2 og klemringen 1 kan også oppnås f.eks. ved å slipe til den pinnen som kan plasseres i det øverste hullet C til en hensiktsmessig lengde som eliminerer klaringen. Denne justering bør da skje i forbindelse med montering av klemring og skaft. En annen mulighet for eliminering av klaringen, er at det rundt leddet 3, mellom rørets innside'og klemringen plasseres fjærelementer eller skims. If the shaft 2 consists of a standard pipe, it may prove necessary to eliminate the clearance that must necessarily exist between the thickness of the clamping ring 1 and the internal dimensions of the pipe due to the relatively large pipe tolerances. This can be carried out by one or more embossing of the pipe 2 after the clamping ring 1 has been installed. Depressing can be carried out alternatively on one or both sides of the pipe. The elimination of undesirable clearance between the shaft 2 and the clamping ring 1 can also be achieved, e.g. by grinding the pin which can be placed in the top hole C to a suitable length which eliminates the clearance. This adjustment should then take place in connection with the installation of the clamping ring and shaft. Another possibility for eliminating the clearance is that around joint 3, between the inside of the tube and the clamping ring, spring elements or shims are placed.
