摘要:
A watertight foldable system comprises a watertight panel in which folds have been made such that the panel may be folded from a flat state into an open-top watercraft such as for example a canoe. The panel comprises a set of folds such that the watercraft, after it has been folded into watercraft, has a bottom having a flat profile in longitudinal direction or having a convex profile relative to the watercraft.

The invention concerns a craft (10) transportable by road by being hitched at the rear of a vehicle, comprising two wheels (14, 16) capable of being extended from their housing (18) into running position through an opening in the housing (18), each wheel being coupled by a shaft (34) to one first end of a lever arm (32), the assembly being articulated on a shaft integral with the hull (12), and the second end of the lever arm being coupled by a shaft (36) to a shock absorber (38) fixed to a first support (42) for maintaining the wheels (14) in extended position. When the wheels are retracted in the housing, a trap door (50) integral with the lever arm (32) is urged to come to stop on a boss to close the housing (18) opening after the shock absorber has been released and fixed on a second support (52) integral with the lever arm (32) and after the lever arm has been fixed to a third support integral with the hull, so as to close the opening completely, thereby preventing water from penetrating into the housing where the wheel is located.

Bow and stern sections (1, 2) of a boat are hinged together to enable the bow section (1) to be folded over the stern section (2) which has wheels (6) deployed for towing and storage on land. The folded boat is towed by a towbar (10) bolted to a retracted spine (8) of a chassis (7) on which the stern section (2) is mounted. The spine (8) is extendable telescopically to support the unfolded bow section (1), and the wheels (6) are pivotally-mounted on the chassis (7) to be retracted by over-centre operation, into open-bottom compartments (26) of the stern section (2); an interlock with the spine (8) precludes wheel-retraction while the spine (8) is retracted. Spring-biased doors (36) are freed to close the open-bottoms of the compartments (26) in response to retraction of the wheels (6). The hinging of the bow and stern sections (1, 2) is via a panel (5) which is pivoted to both sections (1, 2) and which closes a gap between bulkheads (3, 4) in the folded boat and provides a seat over them when the bow section (1) is unfolded.

Cette remorque est du type comportant une caisse et un couvercle conformés de manière à pouvoir être assemblés dans le prolongement l'un de l'autre pour constituer la coque d'une embarcation. Selon l'invention, elle comprend au moins deux poutres longitudinales constituées chacune par au moins deux éléments télescopiques (13a, 13b), dont celui extérieur (13a) est fixé sur la face extérieure d'une paroi soit de la caisse (3), soit du couvercle (4), et dont au moins un de ceux intérieurs (13b) est destiné, lors de son déplacement, à être engagé dans un logement (15) ajusté à ses dimensions prévu respectivement soit dans le couvercle (4), soit dans la caisse (3).

The foldable wheel support enables the setting in place or retraction of the lifting wheels for boats particularly on high sea conditions without disassembling or reassembling, and with space saving in the boat. It comprises a square cross-section tube (1) secured to the boat to which the cross-section tubes (5, 6) integral of each other and carrying the wheel are hinged. Another square cross section tube (10) inserted inside the tubes (1 and 5) enables the articulation or the maintaining of those tubes in a prolongation state. The partial extraction and the hooking of the tube (10) enables the folding of the support by means of a line (18) or a handle (27). Its reinsertion enables the hooking in a folded position. A new partial extraction of the tube (10) enables the unfolding with the same line.

Un pont combiné de flottaison et de remorquage d'une embarcation possède une structure (10) renfermant l'embarcation du type à jet (16). Une paire de roues (34) sont fixées de manière escamotable à la structure avec un attelage (29) prévu à l'extrémité antérieure et formant une remorque pour le remorquage par la route. Une paire de flotteurs (40) sont fixés de manière extensible aux côtés de la structure (10), la combinaison étant propulsée par l'embarcation à la manière d'un bateau. Un pont résilient (48) est fixé sur un flotteur (40) avec des possibilités de fixation (49) sur l'autre flotteur (40), lorsqu'il est étendu, après avoir libéré l'embarcation de ses amarrages, pour former une plate-forme de flottaison.
摘要:
The invention relates to a container comprising fittings for gripping, handling and securing same, each of said fittings (8) being placed at a corner of the container in the non-deployed position of the container. According to the invention, in the non-deployed position, the container is formed by: a central case (1) having a longitudinal dimension and a transverse dimension, and two extension blocks (2, 3) connected to the central case (1), with at least part of the structure of the central case (1) and of the extension blocks (2, 3) being sealed. In the non-deployed position, the length or width of each of the extension blocks (2, 3) is greater than half the longitudinal or transverse dimension of the central case (1) respectively. The extension blocks (2, 3) can move between the non-deployed position, in which the blocks and the central case (1) are placed at least partially on top of one another, and a deployed position in which each block forms a longitudinal or transverse extension of the central case (1), the thus deployed assembly forming a floating structure having an increased loading surface.
