English Abstract


A canoe capsize recovery apparatus that is attachable to the thwart of a canoe
that can be deployed after
the canoe has capsized by the occupants. The apparatus comprises a sliding
frame member for sliding
from a stored position to a deployed position.


Claims

Note: Claims are shown in the official language in which they were submitted.


CLAIMS
We claim:
1. A canoe capsize recovery apparatus comprising: a frame member for sliding
attachment of said
apparatus to a thwart, said frame member having a top side having a concave
surface and a bottom
side having a concave surface, a floatation member for attachment to said top
side, first temporary
attachment means for attaching the frame member to said thwart, a second
temporary attachment
means for attaching the floatation member to the frame member.
2. The apparatus of claim 1 wherein the bottom side concave surface is
disposed upon a top surface of
said thwart.
3. The apparatus of claim 2 wherein the top side concave surface accepts the
shaft of said floatation
member.
4. The apparatus of claim 3 wherein said floatation member is a paddle.
5. The apparatus of claim 4 wherein the floatation member further includes a
floatation aid disposed
adjacent the distal end thereof.
6. The apparatus of claim 5 wherein said floatation aid is an air-
inflatable floatation bag.
7. The apparatus of claim 6 having a first storage configuration and a second
deployed configuration.
8. The apparatus of claim 7 wherein when in said first storage configuration
the frame member is
disposed on the thwart adjacent to a gunnel opposite a deployment gunnel and
the floatation
member is disposed on a top side of the thwart.
9. The apparatus of claim 8 wherein when in said deployed configuration the
frame member is
disposed adjacent said deployment gunnel and the floatation member is extended
a full length from
the deployment gunnel so that the distal end floatation aid is in the water
thereby applying a
buoyancy torque to the canoe.
10. The apparatus of claim 9 wherein said first temporary attachment means
comprises a first buckle
and a second buckle depending below the bottom side concave surface for
attachment to the thwart.
11. The apparatus of 10 wherein said second temporary attachment means
comprises a third buckle and
a fourth buckle disposed upwards from the top side concave surface for
attachment of the floatation
member to the frame member.

BY
DAVID WOOLDRIDGE
FIELD OF THE INVENTION
This invention relates to watercraft in class 114 and particularly watercraft
with capsize recovery
apparatus in subclass 39.
BACKGROUND OF THE INVENTION
In the context of canoeing there is a requirement for an apparatus to assist
the occupants of a capsized
canoe to right the canoe so that the occupants can climb back into the canoe.
To the best of my
knowledge there is no such apparatus.

DESCRIPTION OF THE INVENTION
Referring to the Figures 1 and 2, there is shown one embodiment of the
invention which is a canoe
capsize recovery apparatus. The figures show the hull of a canoe 12 in a cross-
sectional view in Figure
1 and a top view in Figure 2. The canoe has a left side gunnel 14 and a right
side gunnel 16 a front
seating apparatus 18 and a rear seating apparatus 20, a yoke 22 and a thwart
24.
Still referring to Figures 1 and 2 the apparatus of the invention comprises
frame member 30 attached to
the thwart 24 and a floatation member 32 attached to the floatation member.
The invention may also
include an optional floatation aid 34 such as an air inflatable bag attached
temporarily to the distal end
36 of the floatation member 32.
Referring now to Figure 3, there is shown a drawing of one embodiment of the
frame member 50. The
frame member is in sliding attachment with the thwart 24 from a storage
position to a deployed
position as shown in Figure 1 and Figure 2. The frame member has a top side 52
having a concave
surface 54 and a bottom side 56 having a concave surface 58. The floatation
member 32 in Figure 2
attaches to the top side using a first temporary attachment means comprising
two buckles 60 and 62.
The frame member 50 attaches to the thwart using two more buckles 64 and 66
which are disposed
inside of buckles 60 and 62 respectively.
Referring to Figure 4, there is a side view of the frame member 50 attached to
the thwart 24 and
attaching a floatation member 32. Top buckles 60 and 62 are shown attaching
the floatation member
32 to the frame member 50 and buckles 64 and 66 are shown attaching the frame
member 50 to the
thwart 24.
Referring to Figure 5, there is shown a top view of the frame member 50 and
Figure 6 shows a side
view of the frame member. The top side 52 has a concave surface 54 and the
bottom side 56 has a
concave surface 58. The attachment buckles 62 to 66 are drawn tight over the
rounded surfaces 70 and
72 on the left side and 76 and 78 the right side.
Figure 7 shows another embodiment of the frame member 80 in cross-section.
Figure 8 shows an assembled diagram of the apparatus.
