Description

Mordningen, som utgjør en sfærisk virkende rogaffel, har det generelle formålet at den skal kunne benyttes både i kapp— roningsbåter og i vanlige robåter. The device, which forms a spherical-looking rudder fork, has the general purpose of being able to be used both in racing rowing boats and in ordinary rowing boats.

Det er tidligere kjent en rekke rogaffler for å lette riktig bruk av årer» Det er også kjent anordninger som skal kunne hindre at årene faller ut under bruk. A number of rogaffles have previously been known to facilitate the correct use of oars" Devices are also known which should be able to prevent the oars from falling out during use.

Manglene ved de kjente utførelsene er at de ikke oppfyller de krav man bør kunne stille til bruk av rogaffler under forskjell-igartede anvendelser. En annen mangel er at de ikke kan be— nyttes både i kapproningsbåter og i vanlige robåter. The shortcomings of the known designs are that they do not meet the requirements one should be able to set for the use of rogaffles in differential applications. Another shortcoming is that they cannot be used both in racing boats and in normal rowing boats.

Oppfinnelsens særegne formål tar sikte på å fremstille et beslag som kan sikre at årene alltid får en riktig stilling i vannet og at de er sikret mot å falle ut av båten eller mot å forskyve seg på tvers av denne. The particular purpose of the invention is to produce a fitting which can ensure that the oars are always in the correct position in the water and that they are secured against falling out of the boat or against shifting across it.

Denne oppgave er løst ved å fremstille en rogaffel som består This task is solved by producing a fork that consists of

av en hylse som kan skrues fast til båtens esing og ved å anbringe i dette en svingbar og i høyden regulerbar og låsbar gaffel, hvori er anbragt en svingbar festering som er forsynt med en lagerhylse som kan tillate en viss vridning av årebladet, men som også kan låse åren fast i årens periferiretning og samtidig låse åren fast til rogafflen i én i årens lengderetning regulerbar stilling. of a sleeve which can be screwed to the boat's esing and by placing in this a pivotable and height-adjustable and lockable fork, in which is placed a pivotable fastening ring which is fitted with a bearing sleeve which can allow a certain twisting of the oar blade, but which also can lock the oar firmly in the peripheral direction of the oar and at the same time lock the oar firmly to the fork in one adjustable position in the longitudinal direction of the oar.

Konstruksjonen oppviser følgende fordeler: The construction has the following advantages:

1. Rogafflen kan benyttes både i kapproningsbåter og i vanlige robåter. 2. Nar årene er anbragt i sikret stilling i rogafflene, vil de 1. The rowing fork can be used both in rowing boats and in normal rowing boats. 2. When the oars are placed in a secured position in the roga forks, they will

ikke kunne falle ut av båten. could not fall out of the boat.

Årene vil heller ikke kunne forskyve seg på tvers av båten. 4. Årene kan låses fast til rogafflen, så de alltid vil innta en riktig stilling skrått i forhold til vannet. 5. Årene kan også innstilles og sikres til rogafflen slik at de tillates en ønsket begrenset vridning i begge perifere retninger. The oars will also not be able to shift across the boat. 4. The oars can be locked to the oar fork, so they will always take a correct position obliquely in relation to the water. 5. The oars can also be set and secured to the rogaffle so that they are allowed a desired limited twist in both peripheral directions.

Rogafflens høyde over esingen er regulerbar. The height of the row fork above the esing is adjustable.

7. Man kan slippe årene mens de er i vannet, eller svinge dem inn i båten igjen, uten at dette innvirker på årenes stilling når de tas i bruk.igjen. 8. Rogafflene kan lett fjernes sammen med årene fra det fast-stående hylsebeslaget uten bruk av verktøy og kan anbringes i riktig stilling igjen uten reguleringer av n«e slag. 7. You can release the oars while they are in the water, or swing them back into the boat, without this affecting the position of the oars when they are put into use again. 8. The rowing forks can be easily removed together with the oars from the fixed sleeve fitting without the use of tools and can be placed in the correct position again without adjustments of any kind.

Et utførelseseksempel på oppfinnelsen er vist på figurene 1-10, hvor figurene 1-3 viser et hylsebeslag, sett henholdsvis fra enden, ovenfra og fra siden, fig. 4 viser en rogaffel med innsatt festering, sett fra enden, figurene 5 og 6 viser henholdsvis en festering med innsatt låsebrikke, lagerhylse og låsering, sett fra siden i snitt og fra enden, figurene 7 og 8 viser en lagerhylse, sett henholdsvis fra siden og fra enden, mens figurene 9 og 10 viser en låsering, sett henholdsvis fra siden og fra enden. En til båtens esing festbar plate 1 har et sammenskrubart klammer 2 hvori er nedsatt en hylse 3» Ned i denne hylsen er det satt en An embodiment of the invention is shown in figures 1-10, where figures 1-3 show a sleeve fitting, seen respectively from the end, from above and from the side, fig. 4 shows a fork with inserted mounting ring, seen from the end, figures 5 and 6 respectively show a mounting ring with inserted locking piece, bearing sleeve and locking ring, seen from the side in section and from the end, figures 7 and 8 show a bearing sleeve, seen respectively from the side and from the end, while figures 9 and 10 show a locking ring, seen from the side and from the end respectively. A plate 1 that can be attached to the boat's esing has a screw-on clamp 2 in which a sleeve 3" is inserted into this sleeve

ønskelig, ved hjelp av én på hylsen anbragt fjærbelastet sperre— tapp 5« Sperretappens ende hviler i et spor på gafflen som tillater at gafflen kan dreies i horisontalplanet så meget som ønskelig. Rogafflen har to anlegg 6 for innsettelse av ansats— bolter 7« I gafflen er det anbragt, i svingbar stilling, en festering 8. Inne i denne er det anbragt en låsebrikke 9 som kan skrues fast til festeringen ved hjelp av to skrubolter 10. Inn i festeringen skyves en lagerhylse 11 som har en flens 12 hvori er fjernet en sektor på 122° eller et annet gradantall. På motsatt ende av lagerhylsen anbringes en låsering 13 som er forsynt med et hull for en låseskrue 14. Man kan regulere høyden av rogafflen ved å forskyve hylsen 3 opp eller ned i klammeret 2 og strenge hylsen ved hjelp av en skrue i klammeret. desirable, with the help of a spring-loaded lock pin 5 placed on the sleeve. The end of the lock pin rests in a groove on the fork which allows the fork to be turned in the horizontal plane as much as desired. The Roga fork has two devices 6 for the insertion of abutment bolts 7" In the fork, in a pivotable position, a fastening ring 8 is placed. Inside this is placed a locking piece 9 which can be screwed to the fastening ring by means of two screw bolts 10. In a bearing sleeve 11 is pushed into the fastening ring, which has a flange 12 in which a sector of 122° or another number of degrees has been removed. At the opposite end of the bearing sleeve, a locking ring 13 is placed which is provided with a hole for a locking screw 14. The height of the fork can be adjusted by moving the sleeve 3 up or down in the bracket 2 and tightening the sleeve using a screw in the bracket.

Rogafflen kan benyttes alternativt av vanlige turroere og av roere i kapproningsbåter bare ved å regulere de to boltene 10. For vanlige turroere benyttes anordningen på følgende måte: Man stikker åreskaftet 15 passende langt inn i lagerhylsen 11 utenfra og skrur låseskruen 14 mot åreskaftet etterat man har vridd årebladet i riktig skråstilling i forhold til sjøen. The rowing fork can be used alternatively by ordinary tour rowers and by rowers in racing boats just by adjusting the two bolts 10. For ordinary tour rowers, the device is used in the following way: You insert the oar shaft 15 suitably far into the bearing sleeve 11 from the outside and screw the locking screw 14 against the oar shaft after you have twisted the oar blade in the correct oblique position in relation to the sea.

Claims

At the same time, the bolts 10 are screwed in tightly against the sleeve 11 so that it is locked. The oar is thus secured against shifting, both axially and radially, and cannot fall out of the boat either. You can remove the oar with a screwed-on fork by pulling out the locking pin 5" If the fork is to be used by rowers in racing boats, unscrew both bolts 10 slightly and secure them with nuts to spp-raise the blocking of the bearing sleeve 11's movement. You can now turn the oar blade as usual in such boats. The twisting effect is stopped as the edge of the flange 12 on both sides of the sector slot hits the sides of the locking piece 9 and a correct twisting of such veins in both directions is ensured. The sleeve 3 and the fork 4 can be made in one piece and the fastening ring 8 made in two parts. Patent claims. 1.
