Title (EN) WHEEL ASSEMBLY FOR TOWING BOATS
(FR) ENSEMBLE DE ROUES DE REMORQUAGE DE BATEAUX
Abstract:
(EN) An assembly for towing a boat (10) includes a pair of channel members (16, 18) mounted on the transom (14) of the boat and a towing socket (50) formed as part of an upstanding hitch (54) carried on a tow vehicle. A pair of leaf spring supports (20, 22) each carry wheels (44, 46) and stub axles (40, 42) and are pinned to the channel members by means of pivot pins (24, 26) and other removable pins (36, 38) which hold the supports firmly in the channels when the removable pins are in place, which holds the wheels firmly in the lowered position for towing and which permit the supports and wheels to be rotated around the pivot pins to store the wheels when the removable pins are removed. Each of the stub axles includes a hollow extension (40, 42) which supports at its outboard end a rod or shaft (48) serving as a stabilizing bar and the stabilizing bars are held in axial alignment by means of a stabilizing retaining tube (62) supporting the stabilizing bars at their inboard ends.
(FR) Ensemble permettant de remorquer un bateau (10) comprenant une paire d'éléments (16, 18) en forme de canal montés sur l'arcasse (14) du bateau, ainsi qu'une emboîture (50) de remorquage faisant partie d'un attelage (54) droit porté sur un véhicule de remorquage. Une paire de supports (20, 22) à ressort à lame portent chacun des roues (44, 46) et des essieux à chapes fermées (40, 42), et sont chevillés aux éléments en forme de canal au moyen de pivots (24, 26) et d'autres pivots démontables (36, 38) qui maintiennent fermement les supports dans les canaux lorsque les pivots démontables sont en place, ce qui maintient les roues fermement dans la position abaissée pour le remorquage et permet de faire pivoter les supports et les roues autour des pivots afin de ranger les roues une fois les chevilles démontables retirées. Chacun des essieux à chapes fermées comprend un prolongement creux (40, 42) supportant à son extrémité hors-bord une barre ou tige (48) servant de barre stabilisatrice, les barres stabilisatrices étant maintenues en alignement axial au moyen d'un tube (62) de retenue stabilisateur supportant les barres stabilisatrices à leurs extrémités situées en dedans du bord.
