It has a stable structure as it is smoothly prevented from bending in the forward and backward directions of the kayak itself.
  • Such a straight part 80 has a folded part 81 formed by folding concavely along the longitudinal direction on the upper surface of the bottom tube 10b, and a lower surface along the upper surface of the folded part 81 in a V-shaped shape.

Abstract

La présente invention concerne un kayak gonflable dans lequel des tubes latéraux ont des surfaces externes inclinées pour permettre la mise en œuvre appropriée de la structure solide inclinée d'un kayak général, et par le retrait d'espaces vides au niveau de sites de liaison entre un tube inférieur et les tubes latéraux, tous les problèmes et défauts provoqués par l'entrée d'eau dans les espaces vides sont résolus sans à-coups. Ce kayak comprend : un tube inférieur (10) sous la forme d'un tube d'air ; une paire de tubes latéraux (20) disposée des deux côtés de la surface supérieure du tube inférieur (10) ; une paire de bandes inférieures fixées aux deux côtés ouverts du tube inférieur (10) ; une paire de bandes supérieures (40) fixée à des bandes inférieures (30) et les côtés extérieurs ouverts des tubes latéraux (20) ; une paire de premières bandes en V (50) fixées entre les bandes inférieures (30) et les surfaces inférieures des tubes latéraux (20) ; une paire de secondes bandes en V (60) fixées entre les surfaces inférieures des tubes latéraux (20) et la surface supérieure du tube inférieur (10) ; et une paire de bandes d'étanchéité (70) fixées aux côtés internes ouverts des tubes latéraux (20).
