Brassiere with inflation /deflation assembly

1. A brassiere comprising: two breast cups for supporting a breast of a wearer; each said breast cup comprising a plurality of inflatable air envelopes each having at least one internal space which receives air from an air pump;

a connection allowing communicating between the pump and the plurality of inwardly inflatable air envelopes which are along with the pump disposed integrally with and supported in a space between a bra material defining an inner cup surface and an outer cup surface, such that when a pump is actuated, the at least one inflatable envelope is air inflated thereby exerting a displacement force on the breast to enable deformation thereof;

wherein, the connection which allows communications between the pump and the at least one envelope is at least one air valve;

wherein each breast cup comprises a primary envelope having a connection to said pump and which receives air for delivery to the primary envelope;

wherein the primary envelope has a wall arranged so that a series of inflatable individual air pockets are formed therein; and wherein the pump is manually operable to enable pneumatic inflation of the at least one envelope to a size selected by the user;

wherein the pump comprises opposing mutually engagable members which form a pump body; and

wherein at least one of the engagable members comprises a displaceable wall which moves between a first state in which air is discharged from the pump and a second state in which a vacuum is created allowing air to be entrained into the pump.

2. A brassiere according to claim 1 further comprising a plurality of inflatable air envelopes formed by division of a main inflatable envelop into separate inflatable cells.

3. A brassiere according to claim 1 further comprising a midriff band and a fastener for securing the midriff band about the torso of a wearer.

4. A brassiere according to claim 1 further comprising at least one release valve for allowing escape of air from the air pockets.

5. A brassiere according to claim 4 wherein this the at least one release valve allows escape of air from all air pockets in the envelope.

6. A brassiere according to claim 1 wherein the individual air pockets are located in the brassiere cup so they each oppose a distal portion of the wearer's breast.

7. A brassiere according to claim 6 wherein the envelope air pockets are located so that on inflation, the air pockets displace a region underneath or at the sides of the breast.

8. A brassiere according to claim 7 wherein inflation of the envelope causes elevation and lateral displacement of the breast.

9. A brassiere according to claim 1 wherein the pump further comprises a spring bias which urges the displaceable wall to the second state.

10. A brassiere according to claim 1 wherein the pump has an outlet which engages the inlet of the envelope.

11. A brassiere according to claim 1 wherein the pump has a first passage, in which air exiting the pump passes, and a second passage, through which air entering the pump passes.

12. A brassiere according to claim 1 wherein the pump enables connection of one part of a midriff band to another part of a midriff band.

13. A brassiere according to claim 6 wherein the pump further comprises a collar which allows the pump to be detachably fitted to a midriff region of the brassiere.

14. A brassiere according to claim 1 wherein the pump comprises at least one one-way valve.

15. A brassiere according to claim 14 wherein there is one relief valve for each inflatable pocket to enable release of air.
