PONTOON HOUSE BOAT
Abstract
A pontoon house boat supported on a pair of spaced parallel
hollow pontoons provided with a plurality of water tight
compartments. The pontoons are formed of aluminum and have a
plurality of spaced parallel transverse aluminum cross members
welded thereto to support the floor of the house boat, the bow
section, and the steering section. Side and end walls are supported
by upright hollow posts extending upwardly from the deck and a roof
panel is supported on posts which telescope into the aforementioned
posts to move the roof up and down as required. Hinged panels are
connected to the roof section to drop into place to close the side
and end walls with the roof in its uppermost position. Doors give
access to the enclosed space from the bow section and from the
stern steering section with bow section and steering section being
covered by a telescopic roof which slides horizontally to extended
positions. The boat is operated by outboard motors and the roof
section is elevated and lowered by hand or motor drive utilizing a
cable system mounted in the deck mounted post. A drainage system
for water from the roof of the boat utilizes one portion of the
upright post to conduct the water to a point below the floor of the
boat.

DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring now to the drawings in detail, wherein like reference
characters indicate like parts throughout the several figures, the
reference numeral 20 indicates generally a pontoon house boat
constructed in accordance with the invention.
The pontoon house boat 20 includes a pair of hollow aluminum
pontoons 21, 22 arranged in spaced apart parallel relation and each
having a plurality of water tight compartments (not shown). The
pontoons 21, 22 have a plurality of spaced parallel bolsters 23
supporting a plurality of transverse cross frames 24. The cross
frames 24 and bolsters 23 are formed of aluminum and are welded
together to form a rigid structure. The cross frame members 24
provide a flat support for the cabin of the pontoon boat 20.
A plywood floor 25 is secured to the cross members 24 by any
desired means such as pop rivets and a channel member 26 is engaged
over the peripheral edge thereof with its legs extending upwardly.
A side channel member 27 is secured to the end of the cross frame
members 24 to give the boat 20 a more finished appearance. Hollow
generally rectangular posts 28 are secured to adjacent cross frame
members 24 and extend upright therefrom at the corners of the
cabin. Wall panels 29 are secured at their ends to the posts 28 and
are seated in the channels 26 at their lower edges. The wall panels
29 have a channel member 30 covering the upper edge thereof for
strength and appearance.
Wall panels 31 extend transversely of the forward end of the cabin
and have a cabin entrance door 32 hinged centrally thereof. Similar
wall panels not shown close the opposite end of the cabin of the
boat 20.
Front and side panels 33, 34 enclose the deck of the house boat 20
forwardly of the cabin and are provided with double doors 35 to
give access thereto. End and side panels 36, 37 enclose the
opposite end of the deck of the house boat 20 and is similarly
provided with double access doors 38. A hollow generally
rectangular and channel shaped post 39 is telescopically engaged in
each of the post 28 to support at their upper ends a roof structure
40.
The roof structure 40 includes a pair of spaced parallel hollow
beams 41 secured to the upper ends of the post 39 and having an
opening 42 communicating with the post 39. Roof panels 43 have
their ends 44 extending into the beam 41 so that fluid from the
roof 43 may flow into the beam 41 and through the opening 42 down
through the post 39 and out through an opening 45 at the bottom of
the post 28 into the water on which the boat 20 is floating.
A ladder 46 is mounted beneath the floor panel 25 in between a pair
of the transverse frame members 24 so that it may be pulled
outwardly and downwardly to give a swimmer access to the boat. A
retainer hook 47 is positioned on adjacent channel frame members 24
and a transverse pin 48 on each end of the ladder 46 is adapted to
engage therein to retain the ladder 46 in its stored position and
in its extended position as shown in dotted lines in FIG. 13.
A shaft 49 extends transversely of the pontoon boat 20 and is
journalled in bearings 50 mounted on longitudinal supports 51. The
shaft 49 has four drums 52, 53, 54, and 55 respectively associated
with the corner posts 28. A cable 56 is trained over each of the
drums 52, 53, 54 and 55 and extend to the respective posts 28 being
trained over a pair of pulleys 57, 58.
The cable 56 is then trained over pulleys 59 directly beneath the
posts 28 and the cable 56 then extends up the posts 28 and is
trained over a single pulley 60 at the upper end thereof. The
opposite ends of the cable 56 are then engaged in a cable clamp 61
and a bolt 62 extends therethrough securing the cable clamp 61 to
the lower end of the posts 39. Movement of the cable 56 in either
direction will cause the posts 39 to move in the same direction
telescoping into or out of the posts 28. A hand crank 63 and chain
drive 64 is provided for turning the shaft 49 but may be replaced
with any power driven means desired. Rotation of the shaft 49
rotates each of the drums 52, 53, 54 and 55 and extends and
retracts each of the posts 39 simultaneously.
A plurality of rollers 65 are journalled on the innerface of the
beams 41 at each end thereof to support a channel 66 carrying a
telescoping roof structure 67 which is adapted to overlay the
forward and rear portion of the boat 20 out from under the confines
of the roof 40. A telescoping post 68 may be used to support the
roof 67 at its outer most end when desired.
Side panels 69 are hingedly secured at 70 to the roof 40 to drop
from the dotted line position shown in FIG. 7 to the full line
position with the roof 40 in its elevated position. Windows 71 form
part of the side panels 69 and may be opened as desired. Similar
end panels 72 are also hinged to the roof panels 40 and are
provided with windows 73. A door panel 74 is hinged in a frame into
the roof panel 40 and is connected by any desired means (not shown)
to the door panel 32 to operate therewith. With the roof 40
elevated the panels 69 and 72 may be retained in their upper
position or lowered as desired.
In the use and operation of the invention the house boat 20 is
trailered with the roof 40 in lowered position so as to present
less wind resistance and interference with wires, tree limbs and
the like. On reaching the water the roof 40 is elevated and the
boat 20 is normally used with the roof 40 in its elevated position.
In the event that low bridges or other obstructions are encountered
the roof 40 can be lowered to permit passage of the boat 20
thereunder.
Having thus described the preferred embodiment of the invention it
should be understood that numerous modifications and adaptations
may be resorted to without departing from the spirit of the
invention.
