Die erfindungsgemässe Hilfseinrichtung (5), welche auf einem Bootstrailer zu montieren ist, besteht im Wesentlichen aus einem Grundgestell (8) mit Befestigungsmitteln, einer Führungseinrichtung für den Bug eines Bootes mit stehenden Führungsplatten (6,7), welche vom Boot überfahren gegen eine Federkraft niedergedrückt werden können und einer Kupplungsvorrichtung (9), mit welcher der Bug eines Bootes am Grundgestell (8) angeordnet ist, um nach dem Ankuppeln über ein Zugseil eine Winde (4) über die Führungseinrichtung hinaus das Boot in eine gewünschte Endstellung auf den Trailer zu ziehen.
摘要:
Personal watercraft systems are described. The personal watercraft systems include a housing for supporting a water jet engine system. The housing has a pickle fork shaped hull for operation enjoyment. A pair of sponsons is removably attachable to the housing to facilitate breakdown of the watercraft system assembly into more easily transportable components. A cowling is disposed in the housing about the water jet engine system for forming a water jacket about the engine. A support is attached to the housing to support a torso area of an operator. A seal is disposed between the support and the housing for sealing the interface therebetween and absorbing impacts. A steering mechanism is connected to the personal watercraft system for allowing an operator to control the personal watercraft systems direction of travel. The steering mechanism is located below the support for preventing inadvertent operator contact therewith. The systems provide advantages in greater operator comfort and enjoyment from operation of personal watercraft.

Device for launching, hauling and ground handling of vessels (B), comprising an amphibious self-propelled trolley (1) having a tracked frame (2) equipped with a lifting assembly (9), provided with supporting runners (10) for the vessel (B).
摘要:
An amphibious vehicle (1), in the form of an inflatable boat (2) has a self propelled and steerable retractable undercarriage system, enabling the vehicle to enter and exit the water under its own power. The swing of the wheels and their supporting struts (3) & (4) occurs external to the hull of the vehicle. A steerable nose leg (3) is raised or lowered by an actuator situated inside the boat. Stowage is accomplished within the lines of an inflatable craft by the incorporation of fibreglass fairings (5) & (6) sized to match the main inflated tubes (7). Power is provided to the back wheels (4) via an internal drive train within the legs (4). All terrain balloon type tyres are used to enable the boat to travel over a variety shoreline terrain. A steering system engages with the front wheel when the wheel is in its extended position. Motive power is provided by a separate aircooled motor.

The arrangement has at least one retractable steered wheel, and comprises : at least one wheel rotatably mounted on a steerable leg member (18); said leg member (18) being pivotably mounted on pivot means which is pivotable around a substantially horizontal axis (30) relative to a hull of said amphibious vehicle, said axis also being transverse to a longitudinal direction of travel of said hull; a steering arm member (28) operably connected to said steerable leg member (18); means to raise said wheel by pivoting said wheel about said horizontal axis; wherein an end of said steering arm member remote from said steerable leg member is closely adjacent said horizontal axis and operably connected to steering arm moving means.

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.
摘要:
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.
