DETAILED DESCRIPTION
The components of the exemplary system 20 shown in FIG. 1 will be seen include an amphibious boat 22, a tongue 24 and a hitch arrangement 26 .
The amphibious boat 22 is shown in FIG. 2-8 and will be seen to include: a boat 28; a pair of wheel assemblies 30 and a coupling arrangement 32.
The boat 28 includes a body 34 and an outboard motor 36.
The body will be seen to include: a hull 38, a pair of stern seats 40, a pair of intermediate seats 42 and a bow seat 44.
The hull has: a bow 46 and a stern 48; a relatively wide portion 50 including the bow; a relatively narrow portion 52 including the stern; a transition portion 54 that narrows as it connects the bow portion to the stern portion; at the stern, a well 56 having a transom 58 disposed aft of the transition portion.
FIGS. 23-24 show lines for the hull from which persons of ordinary skill will readily appreciate that the hull is shaped to be seaworthy.
As best seen in FIG. 2 :
• the stern seats are disposed aft of the transom and in flanking relation to the well and are filled with a buoyant foam . A suitable foam is that sold under the trademark POLARFOAM which has a density of 40 kg/m3.
• the intermediate seats are disposed in the transition portion.
• the bow seat is disposed adjacent and in spaced relation to the bow and forward of and in spaced relation to the intermediate seats and is similarly filled with buoyant foam.
The outboard motor is, in use, mounted to the transom, as indicated in FIG. 2
The wheel assemblies are of a conventional type which have a wheel 60 rotatably mounted to a pintle 62.
The coupling arrangement includes, for each wheel : a bolt 64; a pin 66; an arm 68; a capture plate 69; a spring mount 70 and a guide plate 72.
The bolt has head 73, a smooth shaft 74 extending from the head and a threaded end 76.
The pin is a quick release ball lock pin.
The arm is a drilled aluminum bar which is in receipt of the pintle and also has an end portion 74 in which a throughbore 75, a smooth bore 76 and a partially threaded bore 78A, 78B are defined, the partially threaded bore terminating in a hollow 79, the throughbore 75 intersecting smooth bore 76 a slot 80 that: defines a pair of forks 82A,82B; bisects the smooth bore 76 radially; and that bisects the partially threaded bore longitudinally, such that one 82A of the forks has a threaded part 78A of the partially threaded bore and the other 82B of the forks has a non-threaded part 78B of the partially threaded bore a socket 77
The spring mount includes an elastic member 86 releasably mounted to the hull and a shaft 88 securely gripped by the elastic member to protrude from the hull, the shaft having an aperture 89 defined therethrough. The sequence of FIGS. 20 and 21 show the manner in which the spring mounts are so releasably received, namely, recesses 89 are defined in the hull which are adapted to receive the spring mounts, and plates 91 are provided which bolt to the hull and capture the spring mounts.
The guide plate 72 has a pair of stop bars 90A,90B and a bore 87 and is rigidly secured to the shaft 88.
The coupling arrangement provides for movement of the arms between :
• a towing configuration, as shown in FIG. 13A-C, wherein, when operatively
positioned, the hull is supported for rolling movement on the wheels when dragged from the bow; and
• a water configuration, as shown in FIGS. 18A-C, wherein, when operatively
positioned, the wheels are alongside the hull, for boating
The manner in which such movement is provided will become evident upon review of the sequence of FIGS. 13A-18C.
As indicated, FIG. 13A-13C shows the towing configuration. In this configuration, the pin 66 extends through the aperture 89 in the shaft and through the
throughbore 75; the fork ends 82A,82B are drawn together by the bolt 64; the shaft 88 is captured in gripping relation within smooth bore 76, as indicated by interference fit dotted line 93; and the bolt head 73 is captured in the hollow 79 by the capture plate 69. This causes the arm to project downwardly and rearwardly from the shaft. It is notable in this regard that the arm rests against stop bar 90A.
A first step in the movement involves a slight loosening of the bolt, to allow the forks to spread slightly apart and the shaft to be held by the arm in transition fit relation, all as shown in FIGS. 14A-14C. It is noted that the bolt cannot be removed entirely, since it is restrained by the capture plate 69.
A second step in the movement involves removal of the spring pin, as shown in FIGS. 15A-15C.
With the pin so removed, the arm can be pivoted until such time as the arm engages the second stop bar 90B, as shown in FIGS. 16A-16C, which defines the water configuration.
The quick release pin can then be inserted through socket 77 and bore 87, as indicated in FIGS. 17A-17C, to lock the arm in the water configuration.
Finally, the bolt can be tightened, to slightly draw the forks together (not visible in the illustrations) and return the interference fit relation to the shaft arm, as indicated in FIGS. 18A-18C by the return of dotted line 93.
The tongue and hitch arrangement defines means for coupling the hull to a vehicle.
The tongue is releasably couplable to the hull by means of a pair of pins 92, as shown by the sequence of FIGS. 1, 8, and terminates in a towing ball receiver 94.
The hitch arrangement has a square tube end 96 adapted to be received by a conventional hitch receiver and carries a towing ball 98 and a winch 100.
In use for towing, the tongue is coupled to the hull, the hitch arrangement is coupled to the hitch receiver and the towing ball is received by the towing ball receiver, all as shown in FIGS. 9,10.
For boating, the tongue can be decoupled from the boat, as indicated by the sequence of FIGS. 9, 11. If the boat is to be returned to the same location for towing, the tongue can be left coupled to the vehicle and pivoted against the vehicle, as shown in FIG. 12. If the boat may be towed by another vehicle in another location, the tongue can be uncoupled from both the vehicle and the boat and transported in the boat to such other location.
Persons of ordinary skill will readily appreciate the aforedescribed structure has great advantage, in that it is towable without the need of a trailer, is relatively easy to convert between towing and boating configurations, is relatively inexpensive to manufacture, is relatively robust in operation, is relatively lightweight, handles relatively well in the water and can service as a utility trailer. In this regard, although not shown, it will be understood that the hull, wheel assemblies and seats are sized, dimensioned and otherwise adapted to permit, among other things, a substantial load to be carried, including but not limited to sheets of plywood that can be laid, flat, on the intermediate seats.
