A rigid or half-rigid cell system with extensible ends, for recreation nautical hulls

Abstract: The rigid or half-rigid system cell system with extensible ends, for recreation nautical hulls, consists of a rigid or half-rigid cell (1) that may be realized out of fibreglass, wood, aliminium or similar, to which one or more extensible parts (3) are fixed and/or joined, or inflatable parts passing through said cell, so as to keep the hull in small dimensions when it is not used while, at the moment of use, said parts are suitable extended or inflated so as to form a functional float.

Description: The present invention concerns a rigid or half-rigid cell system with extensible ends, for recreation nautical hulls. It is well known that the recreation nautical hulls show even considerable lengths which involve considerable difficulties for what concerns transportation and garaging; a single-seater boating canoe may reach a length of 7 to 8 meters, in a fast line for reducing the friction with the water, with rigid structural parts for the fixing of the equipment, and that resist to the continuous efforts and stresses, and it is evident that such structure involves a transportation and garaging problem for the owners. The prior art shown realization systems making use of dismountable frames onto which waterproof coatings may be applied for their whole length, as well as totally inflatable floating systems. For mounting and disassemblying the first, a long time is used, while the inflateable means are not provided with really rigid parts resistant to the different stresses. Document DE-C-396 770 describes a nautical means with progressive formation or realization that need a number of manual operations for assemblying the many elements forming the whole. Furthermore, pushing rods are provided that may be regulated by means of screws for putting into tension the central part with the stem wheel. It is the aim of the present invention to solve a great deal of the requests and difficulties mentioned, by means of a system that reduces the transportation and garaging encumbrance of recreation hulls of different kinds, thus allowing their use to an increasing number of persons. The aim set forth is reached by means of the system according to claim 1. The advantages of the system according to the present invention are many and considerable: a considerable operating safety is assured by the presence of independent watertight compartments, linked one to the other so as to allow the use of the floats provided with said system even as life-boats; the quick operation of extension and reduction of the movable parts facilitates the coming out of the water, beyond the transportation; the production cost is reduced; the possibility of reducing the dimensions may allow beaches and nautical clubs for the garaging of a greater number of floats; the rigid part of the float is resistant to crashes and cuts. The present invention will be described hereinbelow relating to the enclosed drawings in which an embodiment is shown. Figure 1 shows an axometric view of the scheme for the rigid or half-rigid cell system with extensible ends, for recreation nautical hulls. Figures 2 and 3 show the top views of a hull reduced for transportation and garaging, ad of a hull extended for use. Figures 4 and 5 show axonometric views of a hull in its reduced and extended condition. The enclosed figures show a rigid or half-rigid cell system with extendible ends for recreation nautical hulls, comprising: a rigid cell 1 consisting of a concave structure, provided with rowlocks 2, out of fibreglass, wood, aluminium or similar, or in mixtures for making it half-rigid; a plurality of extensible and reductable means, like a tubular 3 or any other shape, fixed and/or joined to said cell 1 with a possible reiforcing structure 6 rolling it up completely or i part, with cloth coating 4 or similar, provided with closing and/or fixing means, like zips or other; possible inflatable tubulars, passing through suitable housings provided in the keel and/or in the edges of cell 1, having the same function of the rigid elements. The length of said cell 1 may vary, according to the present invention, according to the use, for collecting the means for operating the extensibility and the reductibility, for the housing of the user or of the users, for hooking and fixing supports and equipments also under stress. The movable components may have external rigid hollow forms at sight, or internal ones, like elements 5, on stem or on stern, horizontally or vertically, and that may be used for shaping the cloth and for giving a greater functionality to the hull and to its aesthetic. In possible variants of the system according to the present invention, said structure 1 may also not be concave but full, and above it the housing means for the uses, and furthermore the system may be modular with different extensible or inflatable means, that may be applied to cell 1.

Claims: A rigid or half rigid cell system for creating a new nautical hulls of the extensible kind with all mechanical and covering components fixed one to another, charaterized in a central rigid cell (1) consisting of a concave structure provided with towlocks (2), out of fibreglass, wood, aluminium or similar, to which telescopic tubulars (3) are connected, also permanently fixed to the ends of said cell (1), in front and in the back part, thus determining the extension of the hull consisting of a fabric (4) which, due to its extension, forms the final structure. A system according to claim 1, characterized in that said telescopic tubulars (3) are joined to said rigid cell (1) during build-up and form one single structure.
