FR2586395A1 - Demountable floating structure intended for river tourism - Google Patents

Abstract

The invention relates to a demountable floating craft, which is easily transportable as a result of its weight and its volume, which is to make it possible to develop tourism on inland waterways, taking into account its cost price and very low maintenance cost. It consists of a demountable metal framework consisting of beams 5 and 6 and float-holding elements 7. Inflatable floats 8, which are fixed by locking and rapid tensioning straps 9, are fitted to this metal framework; a nylon skirt 3 serves as a false hull and bulwark. Its deck consists of "stretched" nylon net 17 and nylon sheet 18 elements. It comprises jockey wheels 30 for launching. Watertight deck-lockers 33 closed by a lid 34 make it possible to stow loaded equipment.

Description

 The present invention relates to a removable floating structure more particularly intended for pleasure navigation on inland waters.

The floating devices used until then for river tourism (generally rigid hull pleasure boats) are of a high price, they offer a reduced habitability compared to their external dimensions and require, out of season, parking constraints, and above all require significant and costly maintenance.

 The present invention offers future users a machine with a simple and robust removable structure, of a reduced cost price which has excellent reliability according to a particular embodiment allowing two distinct types of river tourism: camping or on-board caravan.

 The design of the machine makes it a particularly reduced and inexpensive maintenance device. Its possible disassembly can allow storage in a very small volume. Its low self-weight makes it easy to transport. Its independent flotation elements make it, on the other hand, practically unsinkable.

 for easier drafting of this document, we will call BATEAU-CASING this removable floating structure intended for river tourism.

 According to the invention, the BOAT-CALPING is constituted by a dismountable framework composed of mechanically welded triangulated beams forming a rectangular frame, and lateral elements called float holders. Under the longitudinal parts of this metal frame is fixed a set of floats made of inflatable materials. This set of several identical elements ensures the safety of the boat in the event of deterioration of one of them. We thus obtain a catamaran type machine.

 Metal railing posts secured to the above-mentioned frame at their upper part, a high railing rail formed by a taut nylon line. A woven flexible nylon skirt, coated on both sides, fixed on the periphery of the BOAT-CAl2PING gives the appearance of a hull and ensures passenger protection by forming a flexible but effective rail.

 A "taut" structure floor composed of a square mesh nylon net and a woven flexible nylon tablecloth, coated on both sides, placed on the upper part of the metal framework allows the user to be isolated from the environment. aquatic and forms the BATEAU-CAISS bridge; G.

 In some places, the bridge is made up of rigid panels or watertight storage bins that fit into the rectangular frame of the metal frame.

 The front of the BATEAU-CSd! PING bridge, treated in the form of a hull, allows the storage of light accessories for river tourism.

 The bridge can support two separate living volumes, depending on the type of river tourism envisaged: either a canopy-canopy shelter volume, suitable for a tent or receive a road caravan, the lower part of the floor of which will level the upper part of the BOAT-CAI bridge * PING; this loading of the caravan is carried out by suitable lifting gear.

 The propulsion of the BOAT-CAMPING is ensured by an outboard motor fixed at the rear and in the aisle of the BOAT-CAMPING. This thruster will have a maximum power of 9.9 CV to comply with river navigation regulations to date.

To clearly understand the invention, the preferred embodiment will be described below, with reference to the schematic drawing in which:
FIG. 1 represents a side view of the BOAT-CAlPING on which the shelter-tent volume has been shown and in short dashed lines, the schematic outline of a road caravan.

 Figure 2 shows a top view of the BOAT-CE SINTG and shows the arrangement of the rectangular frame formed by the metal frame supporting the bridge.

 Figure 3 shows a half cross-section of the BOAT-CAMPING marked A.A.

 Figure 4 is a perspective view showing the attachment of the elements of the metal frame therebetween, during an assembly with 4 beams, the assembly of 3 edge elements being effected identically.

 Figure 5 is a top view showing the attachment of the elements of the metal frame therebetween and specifying the deflection of the gussets to center the longitudinal beams.

 Figure 6 is a perspective showing the float supports and the preferred attachment of the floats on this structure.

 Figure 7 is a diagram showing the system of casters adaptable to the TUMiPIN in to facilitate its launching.

 Figure e shows a front view and a cross section of a railing post eyelet having the preferred method of attachment of the top or bottom rail.

 Figure 9 is a L.B. cross section (see marking in Figure 2) of a waterproof deck box and its ribbed cover.

Referring to Figure 1 there is shown a longitudinal view of the
BOAT-CAMPING on which is represented the canopy-canopy version transformable into a tent (1) and in short broken lines, the outline of a road caravan (2) - (second possible version of river camping). It will be noted that the BOAT-CETING has the generally known appearance of a pleasure boat, the flexible nylon skirt (3) going from the upper edge of the rail to about ten centimeters below the water line (4), forming thus a false shell.

 In Figure 2 there is shown the metal frame of the BATEdU-CAlWING seen from above. There is a rectangular frame formed by longitudinal beams (5), transverse beams (6) and float-carrying elements (7).

 In Figure 3 which is a half cross-section along A.A. of the ship-CM; 2ING, we can distinguish the assembly made by bolts (21) of the elements (5) (6) (7) between them.

 Figure on this last cup A. in the lateral part, the irise in place of one of the elements of the floats (8) fixed on its element (7) by a nylon strap (9) with tension and quick locking, this strap enclosing the float at its cylindrical periphery.

 Note also in Figure 3 the preferred asserublage of the railing posts (10) on the periphery of the metal frame of the 3ATFÀU-CAJING. This assembly is carried out at the same time as the longitudinal beams (5) by 2 bolts (21).

The railing posts (10) are made of bent metal tube to widen the bridge of the 9ATEAU-CAMPING.

 Note the eyelet made at the top of the railing post (10) in which slides the upper railing smooth (11) made by a nylon target. A locking mechanism (see Figure 8) allows the nylon cable (11) to be pinched after tensioning in the eyecup.

 In the lower part of the float-carrying elements (7), an eyelet has been welded into which slides a low smooth rail (12) produced by a nylon cable.

 A locking mechanism (see Figure 8), identical to the upper attachment of the top rail (11) allows the nylon cable (12) to be pinched after tensioning in the eyelet.

The flexible nylon skirt (3) forming a false shell is pierced with metal eyelets
liques (13) at its lower and upper part. Two nylon connecting cords (15) and (16) keep the false shell skirt (3) in position.

 Welded rings on the lateral longitudinal beams (5) allow the tension of a square mesh nylon net (17) acting as a sub-bridge by means of a nylon rope (18) running in ring rings.

 The bridge is made by a 2-sided coated nylon woven tarpaulin (19) comprising eyelets at its lateral part placed on the square mesh nylon net (17) and stretched over the rope (18) by a connecting cord (20).

 Figure 4 shows a perspective of the assembly of 2 longitudinal beams (5) and 2 transverse beams (6). The transverse beams are composed of welded tubes (22) (forming high and low members) on metal end gussets (23) drilled to allow the passage of the fixing bolts (21).

A tube (24) of smaller diameter ensures the triangulation of the beam (6). The longitudinal beams (5) are composed of split tubes (25) flattened and welded to their being on deflected metal gussets (26) shown in Figure 5 so as to center two longitudinal beams (5) consecutive. A tube of smaller diameter (27) triangulates the beam (5). The upper members of the beams (5) and (6) form a plane which defines the upper part of the BOAT- CK ^; PIIJG.

 FIG. 6 shows the preferred method of fixing the floats (8) to the float holders (7). On the flat iron forming a half-moon (27) overlapping the f) ottor (8) are welded two loops (28) allowing the sliding of the fastening straps (9) with rapid tension and blocking. To avoid the longitudinal sliding of the floats (8) in their support (7), hard plastic stops (29) will be glued to the periphery of the float (8) and will come into abutment on the half-moon flat iron (27).

 FIG. 7 shows the preferred construction method for the adaptation of 2 movable jockey wheels (30) installed under the BOAT-CAMPING during its assembly at the water's edge. These wheels are intended to facilitate the launching maneuver of the BOAT-CAIW G.

 In Figure 8, showing a cross section and a front view of a railing post eyelet (10), shows the method of blocking the nylon rope after manual tension. A key (31) and a needle screw (32) pinch the cable (11).

 FIG. 9 represents the cross section L.B. on a metal frame (see referencing in FIG. 2). It shows the installation of a rarely sealed container (33) and its floor cover (34). These very accessible storage spaces, with a volume of around 0.15 m3, allow the storage of all on-board equipment by significantly lowering the center of gravity of the S4TEAU-CAMPING.

 This removable floating structure, intended for river tourism, may find industrial application in the context of the development of this new form of tourism. It can provide spinoffs in very diverse sectors, in particular: mechanical welding, construction of caravans, construction of camping tents, construction of pneumatic floats, etc.
