Abstract
Abstract A play device for suspending a floatable object such as a foam plastic ball or a ping pong ball in an air stream and selectively manipulating the direction and position of the air stream so as to move the ball into areas defined by movable structures. The structures are themselves movable when contacted by the air stream to thereby move the ball-receiving areas and increase the difficulty and excitement of the play of the device. The areas may comprise passageways completely through the movable structures or may be the entrances to receptacles in which the ball may be received or may be defined areas adjacent to portions of the structures. The air stream may be provided by a hand-held blower unit which preferrably includes a cradle for the ball. The cradle includes apertures or openings therein which permits the ball to be lifted by the air stream from a starting position in the cradle and suspended in the air stream a substantial distance above the cradle. This permits the ball to be moved relative to the areas without the blower making physical contact with the movable structures which define the areas. The air stream may have a generally constant thrust so as to maintain the ball a generally constant and predetermined distance from the blower unit. Movement of the ball is accomplished by varying the location of the blower unit (i.e. up, down, or to the side) and by varying the orientation of the unit (i.e., its angle or level, front to back and side to side).

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
110 words
A play device comprising a. a hand holdable blower means for providing a selectively directable air stream; b. a floatable object having such size, shape and weight for being suspended in said air stream; and c. movable means for being disposed on a supporting surface and defining at least one area in which the object is to be positioned by being moved thereto by the air stream, said area being spaced above the supporting surface, said movable means being movable relative to the supporting surface when contacted by the air stream to thereby move the said area and thereby render it more difficult to move the object into the area.
Claim 2
Dependent Claim
110 words
A play device comprising a. a hand holdable blower means for providing a selectively directable air stream; b. a floatable object having such size, shape and weight for being suspended in said air stream; and c. movable means for being disposed on a supporting surface and defining at least one area in which the object is to be positioned by being moved thereto by the air stream, said area being spaced above the supporting surface, said movable means being movable relative to the supporting surface when contacted by the air stream to thereby move the said area and thereby render it more difficult to move the object into the area.
Claim 3
Dependent Claim
23 words
A play device as set forth in claim 1 wherein said movable means defines at least two areas spaced apart from one another.
Claim 4
Dependent Claim
25 words
A play device as set forth in claim 2 wherein at least one of said areas comprises an opening for receipt of the object therein.
Claim 5
Dependent Claim
26 words
The play device as set forth in claim 2 wherein at least one of said areas comprises an aperture for passage of the object completely therethrough.
Claim 6
Dependent Claim
26 words
The play device as set forth in claim 2 wherein at least one of said areas comprises a receptacle for receiving and holding the object therein.
Claim 7
Dependent Claim
44 words
The play device as set forth in claim 1 wherein said means for providing a selectively directable air stream provides such air stream with a substantially constant thrust so as to suspend the object at a essentially constant and predetermined distance from said means.
Claim 8
Dependent Claim
39 words
The play device as set forth in claim 6 wherein said means for providing a selectively directable air stream further includes on-off switch means which are manually operable by the user to turn the air stream on and off.
Claim 9
Dependent Claim
19 words
The play device as set forth in claim 1 wherein said floatable object comprises an essentially spherical lightweight ball.
Claim 10
Dependent Claim
52 words
A play device as set forth in claim 1 wherein said movable means comprises a first movable member which defines one of said areas and a second movable means which is movable relative to said first movable means and which incident to such relative movement imparts movement to said first movable member.
Claim 11
Dependent Claim
155 words
A play device comprising a. a hand-holdable air blower unit for providing a selectively directable air stream of essentially constant thrust, said air blower including manually operable control means for turning said air stream on and off; b. a lightweight floatable ball having such size and weight that it is capable of being suspended in said air stream; and c. means defining at least one area in which the ball is to be positioned by being moved thereto by the air stream, said means including a support structure for being disposed upon a supporting surface and movable area defining means mounted on said support structure defining at least one of said areas, said movable means being movable relative to said support structure when contacted by the air stream to thereby move said area and thereby render it more difficult to move the ball into the area, said area being spaced substantially above the supporting surface.
Claim 12
Dependent Claim
155 words
A play device comprising a. a hand-holdable air blower unit for providing a selectively directable air stream of essentially constant thrust, said air blower including manually operable control means for turning said air stream on and off; b. a lightweight floatable ball having such size and weight that it is capable of being suspended in said air stream; and c. means defining at least one area in which the ball is to be positioned by being moved thereto by the air stream, said means including a support structure for being disposed upon a supporting surface and movable area defining means mounted on said support structure defining at least one of said areas, said movable means being movable relative to said support structure when contacted by the air stream to thereby move said area and thereby render it more difficult to move the ball into the area, said area being spaced substantially above the supporting surface.
