Abstract
Abstract An exercise device is provided with a pair of opposed bellows members which are manually collapsible toward a central member. The central member is provided with an inlet and a plurality of different size outlet apertures, and a check valve to control air flow through the inlet aperture. Collapsing of the bellows members toward the central member causes air to be expelled through a selected one of the outlet apertures. The bellows are then released to return to their original position and the exercise is repeated, thus exercising the chest muscles underlying the user''s breasts to achieve development thereof.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
112 words
A device for developing female breasts through exercise of the underlying chest muscles, which comprises: a pair of opposed bellows members, each of which includes an inner end and an outer end; handle means connected to said bellows members out ends; a central member; said bellows members inner ends being disposed within said central member; said central member having outlet aperture means therein to permit air to be discharged when said bellows members are collapsed by manually pushing said handle means toward said central member; said central member also having inlet aperture means; and valve means to control air flow from said inlet aperture means into the interior of said bellows members.
Claim 2
Independent Claim
112 words
A device for developing female breasts through exercise of the underlying chest muscles, which comprises: a pair of opposed bellows members, each of which includes an inner end and an outer end; handle means connected to said bellows members out ends; a central member; said bellows members inner ends being disposed within said central member; said central member having outlet aperture means therein to permit air to be discharged when said bellows members are collapsed by manually pushing said handle means toward said central member; said central member also having inlet aperture means; and valve means to control air flow from said inlet aperture means into the interior of said bellows members.
Claim 3
Dependent Claim
49 words
A device as defined in claim 1 wherein said valve means consists of a check valve which closes when said bellows members are collapsed, thus preventing air from escaping through said inlet aperture means, but which opens as said bellows members are released to return to their distended position.
Claim 4
Dependent Claim
34 words
A device as defined in claim 1 wherein each of said bellows members includes a shoulder spaced from the inner end thereof and wherein said shoulders abut against said opposite sides of central member.
Claim 5
Dependent Claim
29 words
A device as defined in claim 3 wherein each of said bellows members is substantially circular in cross-sectional configuration and wherein said central member is formed as a ring.
Claim 6
Dependent Claim
24 words
A device as defined in claim 4 wherein each of said bellows members progressively increases in diameter from its outer end to its shoulder.
Claim 7
Dependent Claim
31 words
A device as defined in claim 5 wherein each of said handle means is generally dome shaped in configuration and is adapted to fit into the palm of a user''s hand.
Claim 8
Dependent Claim
39 words
A device as defined in claim 1 further including a first depressed portion in one of said bellows members, between the shoulder and the inner end thereof, said depressed portion forming with said central member, an inlet air chamber.
Claim 9
Dependent Claim
47 words
A device as defined in claim 7 wherein said inlet air chamber is aligned with said inlet aperture means and wherein said valve means is mounted within said first depressed portion to control air flow from said inlet air chamber into the interior of said bellows members.
Claim 10
Dependent Claim
31 words
A device as defined in claim 7 further including a second depressed portion in one of said bellows members, said depressed portion forming with said central member, an outlet air chamber.
Claim 11
Dependent Claim
52 words
A device as defined in claim 9 wherein said outlet aperture means comprises a plurality of apertures of differing sizes and wherein said bellows members having said second depressed portion therein is movable relatively to said central member to align said outlet air chamber with a selected aperture of a selected size.
