Den foreliggende opfindelse angår en anordning for fastgørelse af en flyder samt et anker til en bøjestang.The present invention relates to a device for attaching a float as well as an anchor to a bend bar.

Der kendes forskellige fastgørelsesanordninger, hvor for eksempel et 5 stykke tovværk eller lignende er fastgjort til bøjestangen, og er forbundet med et øje. I dette øje monteres en karabinhage for et anker samt en karabinhage for en bøje. Denne type er problematisk, idet fastgørelsen af rebet, således at det ikke skrider på bøjestangen, er vanskelig. Der er også problemer med slitage på rebet.Various fasteners are known in which, for example, a 5 piece rope or the like is attached to the bend bar and is connected to an eye. In this eye, a carabiner hook for an anchor and a carabiner hook for a buoy are mounted. This type is problematic, as fastening the rope so that it does not slip on the bend bar is difficult. There are also problems with wear on the rope.

Der kendes også fastgørelsesanordninger, hvor et reb, der er forsynet med et øje til fastgørelse af ankre, understøtter en cylindrisk flyder, der fastkiles på bøjestangen. I denne konstruktion fastbindes den cylinderformede flyder både ved oversiden og undersiden. Imidlertid er 15 denne konstruktion også forbundet med slitage på selve fastgørelsesanordningen, som udgøres af rebet og øjet.Also known are fasteners where a rope provided with an eye for fastening anchors supports a cylindrical float which is wedged onto the bend bar. In this construction, the cylindrical float is fixed both at the top and bottom. However, this construction is also associated with wear and tear on the fastener itself, which is constituted by the rope and the eye.

I DK-patentskrift nr. 155.378 beskrives en afmærkningsbøje med et opdriftslegeme. I skriftet er der beskrevet to måder, hvorved opdrifts-20 legemet fastholdes til afmærkningsbøjen. I en udførelsesform består afmærkningsbøjen af to dele, en øvre del og en nedre del, der samles i et centralt placeret hul i opdriftslegemet. Selve samlingen sker for eksempel ved hjælp af en bolt og en møtrik. I en anden udførelsesform fastklemmes opdriftslegemet til afmærkningsbøjen ved hjælp af en klem-25 bøsning på flydel egernet. På denne måde kan opdriftslegemets placering på afmærkningsbøjen varieres. Det er imidlertid en nødvendighed, at såvel afmærkningsbøjen som opdriftslegemet i opfindelsen er tilpasset hinanden for, at deres indbyrdes positionering kan fast- eller sammenholdes.DK Patent No. 155,378 describes a marking buoy with a buoyancy body. The writing describes two ways in which the buoyant body is held to the marking buoy. In one embodiment, the marking buoy consists of two parts, an upper part and a lower part, which are assembled in a centrally located hole in the buoyancy body. The assembly itself, for example, is done by means of a bolt and a nut. In another embodiment, the buoyancy body is clamped to the marking buoy by means of a clamping sleeve on the float portion of the squirrel. In this way, the buoyancy of the buoyant body on the marking buoy can be varied. However, it is a necessity that both the marking buoy and the buoyancy body of the invention are adapted to each other so that their positioning can be fixed or held together.

Det er formålet med den foreliggende opfindelse at afhjælpe ulemperne ved de kendte fastgørelsesanordninger og anvise en fastgørelsesanordning, der er let at fremstille og montere på en bøjestang, som kan tilpasses bøjestænger med forskellige radiale udstrækninger, og en 35 anordning, der kan monteres på en bøjestang stort set uafhængig af flyderens udformning. Fortrinsvis for at samvirke med flydere, der fastkileS om bøjestangen.It is the object of the present invention to overcome the disadvantages of the known fasteners and to provide a fastener which is easy to manufacture and mount on a bendable bar which can be adapted to bendable bars of different radial extensions and a device which can be mounted on a bendable bar largely independent of the design of the float. Preferably to cooperate with floaters which wedge around the bend bar.

Dette opnås ifølge opfindelsen med en anordning, som er særpræget ved, at anordningen har en central del samt to endedele, hvoraf mindst én har et jævnt aftagende tværsnit i retning væk fra den centrale del, at den centrale del ved den side, som vender væk fra bøjestangen, omfat-5 ter to fastgørelsesøjer, at anordningen ved den side, som vender mod bøjestangen, har en krum overflade svarende til krumningen på bøje-stangens omkreds, og at de to endedeles væk fra bøjestangen vendende side er forsynet med indsnit til fiksering af reb eller lignende, hvormed anordningen fastspændes på bøjestangen.This is achieved according to the invention with a device which is characterized in that the device has a central part as well as two end parts, at least one of which has an evenly decreasing cross-section in the direction away from the central part, that the central part at the side facing away from the bend bar, two fastening eyes comprise that the device at the side facing the bend bar has a curved surface corresponding to the curvature of the perimeter of the bend bar, and that the two end portions facing away from the bend bar are provided with notches for fixation of rope or the like by which the device is clamped to the bend bar.

En anordning ifølge opfindelsen lader sig let fremstille, for eksempel som et element af sprøjtestøbt plast. Dette element kan let fastgøres ved hjælp af reb, spændebånd eller andet, som fikseres i indsnittene på hver side af den centrale del, det vil sige ovenover og nedenunder 15 fastgøre!sesøjerne. Herved er anordningen fikseret i forhold til bøje stangen, således at der undgås slid på delene.A device according to the invention is easily manufactured, for example as an element of injection molded plastic. This element can be easily secured by ropes, straps or other, which are fixed in the incisions on each side of the central portion, i.e., above and below the securing pins. Hereby, the device is fixed relative to the bending rod, so that wear on the parts is avoided.

Da mindst én af endedelene har et jævnt aftagende tværsnit, kan denne del benyttes til fastkiling af en flyder omkring bøjestangen. Idet an-20 ordningen tillige har en krum overflade, som vender mod bøjestangen, vil den let placeres mod bøjestangen, og såfremt de dele af anordningens flader, der forløber rundt langs omkredsen, har en vis fleksibilitet, kan anordningen tilpasses bøjestænger med lidt forskellige diametre. Dette er ofte tilfældet, når man anvender bøjestænger, der er 25 fremstillet af bambus. Det bemærkes, at man kunne forestille sig en fastgørelse af ankret ved den nederste ende af bøjestangen, i stedet for et fastgørelsesøje, der sidder i umiddelbar tilknytning til flyderen. Imidlertid viser det sig i praksis, at sådanne bøjer, hvor ankret er fastgjort i bunden af bøjestangen, let vil blive slået til bunds af 30 strømmen. Det er derfor vigtigt, at ankret kan fastgøres til bøjestangen i umiddelbar nærhed af flyderen.Since at least one of the end portions has an evenly decreasing cross section, this portion can be used for securing a float around the bend bar. Also, since the device has a curved surface facing the bending rod, it will readily be placed against the bending rod, and if the portions of the surfaces of the device extending around the circumference have some flexibility, the device can be adapted to bending rods of slightly different diameters. . This is often the case when using bend bars made of bamboo. It should be noted that an attachment of the anchor could be imagined at the lower end of the bend bar, rather than an attachment eye that is adjacent to the float. However, in practice, it appears that such buoys, where the anchor is secured to the bottom of the buoy bar, will be easily lowered to the bottom of the stream. It is therefore important that the anchor be attached to the bend bar in the immediate vicinity of the float.

Såfremt anordningen laves stort set symmetrisk med et jævnt aftagende tværsnit i begge retninger væk fra den centrale del, vil anordningen 35 være særlig sikker at bruge, idet der ikke vil være risiko for at vende anordningen forkert og dermed risikere at miste fastkilingseffekten.If the device is made substantially symmetrical with an evenly decreasing cross-section in both directions away from the central portion, device 35 will be particularly safe to use as there will be no risk of reversing the device incorrectly and thus risk losing the wedge effect.

Det er ligeledes fordelagtigt, at øjerne udgøres af et m-formet ele- DK 169317 B1 3 ment, der forløber i anordningens længderetning, således at de to fastgørelsesøjer vil være anbragt umiddelbart ovenover og nedenunder hinanden, når bøjestangen er i brug. I det øverste øje kan der fastbindes en ende af en snor, hvis anden ende fastbindes umiddelbart 5 ovenover den cylinderformede flyder. Herved kan flyderen fastholdes ikke alene ved fastkilingen men tillige ved hjælp af snoren.It is also advantageous for the eyes to be constituted by an m-shaped element extending in the longitudinal direction of the device, so that the two fastening eyes will be placed immediately above and below each other when the bend bar is in use. In the upper eye, one end of a cord may be attached, the other end of which is immediately attached above the cylindrical flow. Hereby the float can be held not only by the wedge but also by the string.

En yderligere fordel kan opnås, såfremt anordningens endedel ved den side, som vender væk fra bøjestangen, har et savtakformet tværsnit. 10 Dette vil danne en slags modhager, når den cylinderformede flyder er fastkilet omkring bøjestangen og den derpå fastspændte anordning.A further advantage can be obtained if the end portion of the device at the side facing away from the bend bar has a saw-shaped cross section. This will form a kind of barbs when the cylindrical float is wedged around the bend bar and the device clamped thereon.

Opfindelsen vil herefter blive forklaret nærmere under henvisning til den medfølgende tegning, der illustrerer én udførelsesform for opfin-15 del sen, cg hvor fig. 1 ' et skematisk billede af anordningen ifølge opfindelsen fast gjort på en bøjestang, fig. 2 viser et sidebillede, delvis i snit, af en fastgørelsesan-20 ordning ifølge opfindelsen, fig. 3 et billede af den i fig. 2 viste anordning set fra den side, der vender væk fra bøjestangen, og fig. 4 et snit følgende linien IV-IV i fig. 2.The invention will then be explained in more detail with reference to the accompanying drawing, which illustrates one embodiment of the invention, cg where FIG. 1 is a schematic view of the device according to the invention attached to a bend bar; FIG. 2 is a side view, partly in section, of a fastener according to the invention; FIG. 3 is a view of the embodiment of FIG. 2, seen from the side facing away from the bending rod, and FIG. 4 is a section along line IV-IV of FIG. 2nd

25 I fig. 1 vises en anordning 1 ifølge opfindelsen. Denne er fastgjort til en bøjestang 2, som omfatter en cylinderformet flyder 3. Ved sin bund er bøjestangen 2 forsynet med en ballast 4, og ved toppen er der tilvejebragt et flag 5.In FIG. 1, a device 1 according to the invention is shown. This is attached to a bend bar 2 which comprises a cylindrical float 3. At its bottom, the bend bar 2 is provided with a ballast 4 and at the top a flag 5 is provided.

30 Fastgørelsesanordningen 1 omfatter en central del 6 samt to endedele 7,8 ved hver ende heraf. Ved hver af de to endedele 7 og 8 er der anbragt reb 9, hvormed anordningen er fastspændt til bøjestangen 2. Rebet er fikseret i riller 10, der særlig tydeligt fremgår af de efterfølgende figurer.The fastener 1 comprises a central portion 6 and two end portions 7,8 at each end thereof. At each of the two end portions 7 and 8, rope 9 is provided, whereby the device is clamped to the bend bar 2. The rope is fixed in grooves 10, which is particularly evident in the following figures.

I fig. 2-4 ses fastgørelsesanordningen. I den viste udførelsesform er anordningen 1 symmetrisk og omfatter to identiske endedele 7,8, hvilket forhindrer en forkert montering. Ved monteringen vil den jævnt af- 35 DK 169317 B1 4 tagende ydre flade 11, der vender væk fra bøjestangen, være medvirkende til at flyderen 3 fastkiles. Den centrale del 6 omfatter to øjer 12,13. De to øjer er dels beregnet til fastgørelse af flyderen 3 ved hjælp af et reb 14 (se fig. 1). Rebet 14 er forbundet til øjet 12 og 5 ved et punkt 15 umiddelbart ovenover flyderen 3. Øjet 13 er beregnet til fastgørelse af et anker, for eksempel ved hjælp af en karabinhage (ikke vist). Således fastgøres ankret til bøjestangen umiddelbart under flyderen 3.In FIG. 2-4, the fastener is shown. In the illustrated embodiment, the device 1 is symmetrical and comprises two identical end portions 7,8, which prevents incorrect mounting. During mounting, the evenly exterior surface 11 facing away from the bend bar will smoothly remove the float 3. The central portion 6 comprises two eyes 12,13. The two eyes are partly intended to attach the float 3 by means of a rope 14 (see Fig. 1). The rope 14 is connected to the eye 12 and 5 at a point 15 immediately above the float 3. The eye 13 is intended to attach an anchor, for example by means of a carabiner hook (not shown). Thus, the anchor is attached to the bend bar immediately below the float 3.

10 Anordningen 1 er fortrinsvis dannet med en skalform, som tydeligt fremgår af snitbilledet i fig. 2. Denne skal form er fordelagtig af støbetekniske hensyn, men tillader tillige at anordningens sidedele 16,17 (se fig. 3) kan give sig en lille smule, således at anordningen kan tilpasses forskellige diametre for bøjestænger 2.The device 1 is preferably formed with a shell shape which is clearly shown in the sectional view of FIG. 2. This shell shape is advantageous for casting technical reasons, but also allows the side parts 16,17 of the device (see Fig. 3) to give a little bit, so that the device can be adapted to different diameters for bending rods 2.

De to øjer 12,13 er dannet i form af et m-formet element 18 (se fig.The two eyes 12,13 are formed in the form of an m-shaped element 18 (see fig.

4), der er fremspringende i det væsentlige radialt udefter, og som danner øjer 12 og 13 med en sådan størrelse, at karabinhager eller reb kan fastgøres deri. Dette betyder, at anordningen normalt har en høj-20 de, der er mellem ca. 30 og 50 mm og en total længde, der er mellem 200 og 300 mm.4) projecting substantially radially outwardly, forming eyelets 12 and 13 of such size that carabiner hooks or ropes may be secured therein. This means that the device usually has a height which is between approx. 30 to 50 mm and a total length between 200 and 300 mm.

Det m-formede element 18 er ved hver ende forbundet med en jævnt aftagende ribbe 19, som sikrer at konstruktionen er stiv og modstandsdyg-25 tig overfor de påvirkninger, som øjerne udsættes for.The m-shaped member 18 is connected at each end to an evenly decreasing rib 19 which ensures that the structure is rigid and resistant to the stresses to which the eyes are exposed.

Anordningen vil almindeligvis fremstilles af et slag- og frostsikkert plast, således at det kan tåle den håndtering og de vilkår, som den udsættes for under håndtering og brug. Et eksempel på egnet materiale 30 kan også være nylon. Det bemærkes, at det også vil være muligt at fremstille anordningen af fiberforstærkede plastmaterialer, såfremt dette er ønsket af hensyn til styrken.The device will generally be made of impact-resistant and frost-proof plastic so that it can withstand the handling and conditions to which it is subjected during handling and use. An example of suitable material 30 may also be nylon. It will be noted that it will also be possible to make the device of fiber-reinforced plastic materials, if this is desired for the sake of strength.

Opfindelsen er forklaret under henvisning til én specifik udførelses-35 form, men inden for opfindelsens omfang vil det være muligt at foretage modifikationer. Således vil det for eksempel være muligt at forsyne den side af anordningen, der vender mod bøjestangen, med en friktionsbelægning for at opnå en fast indbyrdes positionering af anordningen 1 5 DK 169317 B1 og bøjestangen 2 for derved at minimere risikoen for slid mest muligt.The invention is explained with reference to one specific embodiment, but within the scope of the invention it will be possible to make modifications. Thus, for example, it will be possible to provide the side of the device facing the bend bar with a friction coating to achieve a fixed positioning of the device 1 and the bend bar 2, thereby minimizing the risk of wear.

Anordningen behøver ikke kun at anvendes sammen med en cylindrisk fly der. Den kan med fordel anvendes sammen med kugleformede flydere, der 5 fastgøres til øjet 12 ved hjælp af karabinhager eller lignende.The device need not only be used with a cylindrical aircraft there. It may advantageously be used with spherical floats that are attached to the eye 12 by carabiner hooks or the like.
