Description
Foreliggende oppfinnelse vedrører en klemkobling bergegnet på å gripe rundt et sylindrisk legeme, slik som en stang eller rør, og holde det fast. The present invention relates to a clamp coupling suitable for gripping around a cylindrical body, such as a rod or pipe, and holding it firmly.
Fra tidligere er det i handelen et produkt kalt "Lettløfter'n", norsk designregistrering 79052. Dette er et ekstra håndtak beregnet på å festes fremme på det vanlige skaftet av en spade eller snøskuffe. Brukeren kan da arbeide med rettere rygg. Det ekstra håndtaket festes med en klemkobling. Denne klemkoblingen griper godt rundt skaft med 38 mm diameter, men er begrenset til skaft med nøyaktig denne diameteren, dvs. at klemkoblingen ikke kan brukes på skaft med litt større eller mindre diameter. Dette begrenser anvendelsesområdet for Lettløfter'n til redskap av en størrelse. From the past, there is a product in the trade called "Lettløfter'n", Norwegian design registration 79052. This is an extra handle intended to be attached to the front of the normal handle of a shovel or snow shovel. The user can then work with a straighter back. The additional handle is attached with a clamp connection. This clamp coupling grips well around shafts with a diameter of 38 mm, but is limited to shafts with exactly this diameter, i.e. the clamp coupling cannot be used on shafts with a slightly larger or smaller diameter. This limits the area of application for the Light Lifter to implements of one size.
Det er derfor en hensikt med foreliggende oppfinnelse å fremskaffe en klemkobling som kan benyttes på sylindriske legemer med varierende diameter. It is therefore an aim of the present invention to provide a clamp connection which can be used on cylindrical bodies of varying diameter.
Dette oppnås med en klemkobling slik som definert i de vedføyde patentkrav. This is achieved with a clamp connection as defined in the attached patent claims.
Oppfinnelsen skal nå beskrives i detalj med henvisning til de vedføyde tegninger, hvor The invention will now be described in detail with reference to the attached drawings, where

Lettløfter'n slik den er illustrert i Fig. 1, er et ekstra håndtak som klemmes fast fremme på skaftet av for eksempel en snøskuffe. Selve klemkoblingen, slik den er illustrert i The light lifter, as illustrated in Fig. 1, is an additional handle which is clamped firmly to the front of the shaft of, for example, a snow shovel. The clamp connector itself, as illustrated in
Fig. 2, omfatter en klave med tre sammenhengslede komponenter 1, 2, 3. Komponentene har en indre form tilpasset den runde formen på et skaft. Den første komponenten 1 har i tillegg en hengslet låseklaff 4. Når klemkoblingen klemmes sammen om et skaft, vil låseklaffen 4 gripe inn bakom en låsehake 5 på den tredje komponenten 3, og dreies ned mot yttersiden av den første komponenten, jevnfør Fig. 3. Den andre komponenten 2 har hull for feste av selve håndtaket. Fig. 2 comprises a clave with three connected components 1, 2, 3. The components have an internal shape adapted to the round shape of a shaft. The first component 1 also has a hinged locking flap 4. When the clamp coupling is clamped around a shaft, the locking flap 4 will engage behind a locking hook 5 on the third component 3, and turn down towards the outside of the first component, see Fig. 3. The second component 2 has holes for attaching the handle itself.
Ifølge oppfinnelsen utstyres minst en av komponentene med en pakning, idet pakningen er lagt på innsiden av komponenten mellom klaven og det sylindriske legemet som skal holdes fast. Pakningen er laget av et elastisk materiale, slik som gummi eller et annet materiale som egner seg for formålet. Yttersiden av pakningen er tilpasset formen av den tilsvarende komponent i klaven med støtteribber osv., slik at pakningen kan legges inn i komponenten og holdes fast ved at den fyller opp rommet mellom komponenten og det sylindriske legemet. Ved å supplere med pakninger kan en tidligere kjent klemkobling, begrenset til å gripe og holde skaft av 38 mm diameter, bringes til å holde skaft av 30 - 38 mm diameter eller mer. Videre kan koblingen gripe og holde fast skaft av avtagende diameter, dvs. kon form. Fig. 6 viser pakningen i detalj. Pakningen er buet i samsvar med formen av den tilsvarende komponent i klaven. Yttersiden er formet slik at den fyller ut innsiden av komponenten, og utsiden er forsynt med sugekopper som rager ut fra overflaten av pakningen. Det at sugekoppene står ut fra grunnflaten gjør at klemkoblingen kan gripe legemer av varierende diameter. Når klemkoblingen klemmes rundt det sylindriske legemet, vil sugekoppene klemmes ned mot underlaget slik at det dannes et vakuum under i det minste noen av koppene. Dette får klemkoblingen til å holde meget godt på det sylindriske legemet. Fig. 7 viser klemkoblingen utstyrt med pakninger i alle komponenter. Den vil da gripe rundt hele omkretsen av legemet som skal holdes. According to the invention, at least one of the components is equipped with a gasket, the gasket being placed on the inside of the component between the clave and the cylindrical body which is to be held firmly. The gasket is made of an elastic material, such as rubber or another material suitable for the purpose. The outer side of the gasket is adapted to the shape of the corresponding component in the clave with support ribs, etc., so that the gasket can be inserted into the component and held firmly by filling up the space between the component and the cylindrical body. By supplementing with gaskets, a previously known clamp coupling, limited to gripping and holding shafts of 38 mm diameter, can be made to hold shafts of 30 - 38 mm diameter or more. Furthermore, the coupling can grip and hold firmly a shaft of decreasing diameter, i.e. cone shape. Fig. 6 shows the packing in detail. The gasket is curved in accordance with the shape of the corresponding component in the clave. The outside is shaped so that it fills the inside of the component, and the outside is provided with suction cups that protrude from the surface of the gasket. The fact that the suction cups protrude from the base surface means that the clamp coupling can grip bodies of varying diameter. When the clamp coupling is clamped around the cylindrical body, the suction cups will be clamped down against the substrate so that a vacuum is formed under at least some of the cups. This causes the clamp coupling to hold very well on the cylindrical body. Fig. 7 shows the clamp connection equipped with gaskets in all components. It will then grip around the entire circumference of the body to be held.
Oppfinnelsen omfatter en klemkobling som er universelt anvendelig i alle situasjoner hvor det er behov for å feste noe til et sylindrisk legeme, det kan være å koble noe til legemet, holde legemet fast, eller for eksempel skjøte to sylindriske legemer. Oppfinnelsen er ikke begrenset til å anvendes på skaft til redskap. The invention includes a clamp connection which is universally applicable in all situations where there is a need to attach something to a cylindrical body, it can be connecting something to the body, holding the body firmly, or for example joining two cylindrical bodies. The invention is not limited to use on tool handles.
Videre kan det være et vilkårlig antall komponenter i klemkoblingen, med pakninger under alle, eller et vilkårlig antall av komponentene. Pakningene kan være innrettet til bare å dekke området rundt hver sin komponent, eller være forlenget slik at de dekker et område utenfor den tilhørende komponent, slik som en naboliggende komponent, eller området under hengslingen mellom de to komponentene. Furthermore, there can be an arbitrary number of components in the clamp connection, with gaskets under all of them, or an arbitrary number of the components. The gaskets can be designed to only cover the area around each component, or be extended so that they cover an area outside the associated component, such as an adjacent component, or the area under the hinge between the two components.
For å øke virkningen av klemkoblingen, kan låseklaffen 4 gjøres eksentrisk rundt hengsellinjen, slik at den danner en kam på den siden som vender inn mot pakningen (ikke vist). Ved låsingen av klemkoblingen vil låseklaffen gripe rundt baksiden av låsehaken 5 og presses innover slik at den ligger tilnærmet tangensialt med det sylindriske legemet. Samtidig vil kammen på baksiden av låseklaffen presses innover mot pakningens bakside. Fig. 8 viser en adapter som er innrettet til å legges inn i klemkoblingen for å tillate at koblingen kan gripe legemer av firkantet form. Adapteren er laget av plast, i to deler som henger sammen i en hengsellinje. Den er beregnet til å legges inn i klemkoblingen. Fig. 9 viser en adapter som er utstyrt med pakning på innsiden. Pakningen kan utformes med flat eller sylindrisk innside, slik at den kan gripe rundt legemer med enhver form. Utgaven vist i figuren er utformet for å gripe sylindriske legemer. To increase the effectiveness of the clamp coupling, the locking flap 4 can be made eccentric around the hinge line, so that it forms a ridge on the side facing the gasket (not shown). When the clamp coupling is locked, the locking flap will grip around the back of the locking hook 5 and be pressed inwards so that it lies approximately tangentially to the cylindrical body. At the same time, the cam on the back of the locking flap will be pressed inwards towards the back of the gasket. Fig. 8 shows an adapter adapted to be inserted into the clamp coupling to allow the coupling to grip bodies of square shape. The adapter is made of plastic, in two parts that hang together in a hinge line. It is intended to be inserted into the clamp connection. Fig. 9 shows an adapter which is equipped with a gasket on the inside. The gasket can be designed with a flat or cylindrical inside, so that it can grip around bodies of any shape. The version shown in the figure is designed to grip cylindrical bodies.
Det kan også benyttes adaptere hvor selve innsiden er sirkulær, dvs. for å gripe sylindriske legemer med mindre diameter, for eksempel 12-14 mm. Med to lag pakninger oppnås en meget stabil kobling. Adapters can also be used where the inside itself is circular, i.e. to grip cylindrical bodies with a smaller diameter, for example 12-14 mm. With two layers of gaskets, a very stable connection is achieved.
