WATER SPORT PLATFORMS
Abstract
A pair of jousting poles and a pair of inflatable rafts each
raft having a flexible wall for supporting a water sport player in
the inflated condition and for collapsing and letting the player
down or tipping him into the water in the deflated condition. An
escape valve is mounted on the wall of the raft and this valve is
connected to an arm supporting a target. When the target is hit by
a jousting pole carried by an opposing water sport player, the arm
is moved and opens the escape valve causing the raft to deflate and
collapse.

Description
SUMMARY OF THE INVENTION
This invention relates generally as indicated to apparatus for a
water sport or contest in which the players kneel on buoyant
supporting platforms. Each platform has a disclike target mounted
at the forward edge which is connected to a valve or other means
for decreasing the buoyancy of the platform. A pole is carried by
each player with which he attempts to strike the target on the
opposing player's platform. He also uses this pole to defend his
platform by deflecting the pole of the opposing player away from
the target on his platform. Each pole may have padding on one end
to prevent injury of the players and a paddle at the other end
which can be used to maneuver the platform.
To the accomplishment of the foregoing and related ends the
invention then comprises the features hereinafter fully described
and particularly pointed out in the claims, the following
description and the annexed drawing setting forth in detail a
certain illustrative embodiment of the invention. This being
indicative, however, of but one of the various ways in which the
principles of the invention may be employed.
BRIEF DESCRIPTION OF THE DRAWINGS
In the annexed drawings:
FIG. 1 is a side elevation view of a preferred form of floatable
support or platform constructed in accordance with this invention
showing how two of the platforms are used during the playing of
this game.
FIG. 2 is an enlarged fragmentary front elevation view of the
floatable support taken along the plane of the line 2-2 of FIG.
1.
FIG. 3 is a fragmentary longitudinal section through the target
valve mechanism and platform taken along the plane of the line 3-3
of FIG. 2.
FIG. 4 is an enlarged fragmentary view like FIG. 3 showing a
modified form of valve arrangement.
DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring now in detail to the drawings and first, especially to
FIG. 1, the floatable support or platform 1 illustrated herein by
way of example includes a buoyant container such as inflatable
casing 2 having a top wall portion and horizontal supporting
surface 3 on which the players 4 may kneel. The normal floating
position of the platform with a water line WL is shown in FIGS. 1,
2, and 3. Each player 4 may carry a pole 5 having a paddle 6 at one
end and a soft padded cover 7 at the other end.
The inflatable casing 2 has a wall 8 of flexible rubber or other
rubberlike material such as polyvinyl chloride which is impervious
to air or other inflating gasses. The wall 8 may be reinforced by
cords of cotton, rayon or nylon (not shown) if desired. Preferably,
the casing 2 has a flat bottom wall portion 9 which is connected to
the supporting surface 3 by reinforcing members or webs 10, which
may be of the same or similar material used for the casing wall 8,
These webs 10 retain the shape of the casing 2 when it is inflated.
Openings 11 in the webs 10 are located at intervals along the webs
to permit substantially unrestricted flow of air through the casing
as shown by the arrows in FIG. 3.
Edge portion 12 of the wall casing 2 may have a tubular
configuration in the inflated condition to provide stability and
maneuverability of the platform 1. The casing 2 may also be
constructed with a greater length than width or if desired, may be
of a circular configuration. In any case the depth is preferably
less than either the width or length of the casing 2 to provide the
necessary stability and support for the players.
At the edge portion 12 of the casing 2 faced by the player being
supported, an opening 13 is provided in the wall 8. A tube 14 of
metal or other rigid material is disposed in the opening 13 and may
have a flanged end 15 which is mounted in sealing engagement with
the casing wall 8 so that the tube projects horizontally forward
from the casing 2 providing a passage and outer end 16 of the tube
through which air may pass. Preferably, a separate inflation valve
17 is provided in the casing wall 8; however, the casing 2 may also
be inflated through the tube 14 if desired. The separate inflation
valve 17 shown in FIG. 1 is of the type used to inflate beach rafts
and inner tubes and has a connection for attachment to an inflating
device such as an airhose found at most filling stations or a tire
pump.
To contain the air in the casing, a closure such as cap 18 is
disposed over the outer end 16 of the tube 14. This cap 18 may have
a projecting surface or plug 19 conforming substantially to the
opening in the outer end 16 of the tube 14 for holding the cap in
position. A circular gasket 20 of rubber or other rubberlike
material may be disposed around the plug 19 in sealing engagement
with the cap 18 and outer end 16 of the tube 14 when the cap is on
the tube. Preferably, the gasket 20 is adhered to the cap 18 by a
suitable adhesive so that when the cap is removed from the outer
end 16 of the tube 14, the gasket will move with the cap.
A movable member or arm 21 connects the cap 18 to a target 22 which
is disposed above the cap, the casing 2 and the water in which the
casing floats so as to be visible to the players 4. The target 22
may have different shapes but preferably is round with a striking
surface facing forward for receiving pressure from the end of the
pole 5 with the padded cover 7 when a player 4 hits the target as
shown in FIG. 3.
The arm 21 is hinged at the outer end 16 of the tube 14 at the
upper side thereof and has bifurcated lugs 23 disposed on each side
of a lug 24 mounted on the tube. A hinge pin 25 extends in a
horizontal direction through aligned holes in the arm lugs 23 and
the tube lug 24 to permit swinging movement of the arm 21 and the
attached target 22 and cap 18 to open and close the outer end 16 of
tube 14.
As shown in FIG. 3, a spring such as clip 26 is fastened to the
underside of the tube 14 with a hook end 27 over the edge of the
cap 18 to hold it in sealing engagement with the outer end 16 of
the tube 14. When sufficient pressure is exerted against the face
of the target 22 to overcome the clamping force exerted by the clip
16, the cap 18 will swing away from the tube 14 around the hinge
pin 25 as shown in phantom lines in FIG. 3.
It will now be apparent that to inflate the casing 2, the cap 18 is
placed over the outer end 16 of tube 14 in sealing engagement and
the clip 26 snapped over the edge of the cap to hold it in place.
Air is pumped into the casing 2 through inflation valve 17 and the
casing assumes the shape shown in FIG. 1 to provide the necessary
support for a player 4. The player 4 paddles his platform 1 to a
position in close proximity to the platform of his opponent by
means of the paddle 6 at the end of the pole 5. When the player is
within striking distance of his opponent's target 22, he attempts
to strike the target with enough force so that the pressure against
the target will overcome the spring pressure of the clip 26 and
thereby cause the removal of the cap 18 from the tube 14 permitting
the escape of the air from the casing 2. This will cause the casing
2 to completely deflate and reduce the platform buoyancy to the
point where the opponent is no longer supported and is immersed in
the water. Of course, in the meantime, the opponent is also
attempting to strike the target 22 of the platform 1 on which the
first player is kneeling and both players will be using their poles
5 to ward off the attacks on their respective targets 22.
Alternatively, the spring force applied by spring clip 16 may be
applied by a wire of flat steel spring 28 wrapped around hinge pin
25 in the clearance space provided between lug 24 on the tube 14
and arm lug 23. The spring 28 has a movable end 29 bearing against
the arm 21 and a fixed end 30 bearing against the tube 14. Here
again, the arm 21 will be urged in a counterclockwise direction as
seen in FIG. 4 when the target 22 is hit by the pole 5 and if the
pressure on the target is sufficient to overcome the spring force,
the cap 18 will be swung away from the tube 14 permitting passage
of the air out of the casing 2. This escape of air will only
continue while the arm 21 is held in the open position by pressure
on the target 22. Upon release of pressure on the target 22 the
spring 28 of FIG. 4 will force the cap 18 back into sealing
engagement with the end of the tube 14.
It will, therefore, be apparent that with the spring 28 exerting a
continuous closing force on cap 18 the game will be prolonged since
it may take a number of strikes or prolonged pressure on the target
to cause sufficient deflation of the casing 2 to reduce the
platform buoyancy to the point where the player is fully immersed
in the water and loses the game.
From the foregoing, it will be seen that the supporting platform 1
of the present invention is especially adapted for the water sport
described herein and can be easily transported in the deflated
condition to a pool, lake, river or other body of water where there
is sufficient water to float the platforms. Then by use of hand or
foot pumps or compressed gas bottles the casing may be inflated to
provide the platform with the buoyancy needed to support the
player. With the targets in place the players can joust with the
poles providing stimulating exercise requiring the skill of fencing
as well as skill in balancing and maneuvering a watercraft.
Although the game as described here is for only two players, it may
be played with teams of players in which several players on several
platforms form a team to combat a similar group of players.
Likewise, a larger platform may be constructed in accordance with
the invention to support two players, one of whom may paddle and
maneuver the platform while the other jousts with the pole to ward
off attacks against the target on his platform and attempts to
strike the target of the opposing players. It is also contemplated
within the scope of this invention that two or more targets may be
provided on one platform either connected to one closure or a
number of closures for an equal number of openings for deflating
the casing and reducing the buoyancy of the platform.
