Body massage apparatus

Claim 2

Apparatus for body massage comprising: a bed structure having a housing defining an interior massage chamber and an upwardly-facing opening communicating with said massage chamber, and a resiliently flexible membrane affixed to said housing in substantially sealing relation generally horizontally across said opening, said membrane being in sufficiently tensioned condition for forming a primary weight-bearing body support surface on which a user may lay for massage treatment while retaining sufficient resiliency and flexibility in its tensioned condition to generally conform to a user's body, said chamber being substantially filled with air; fluid jet means disposed within said chamber for directing a fluid jet emission at said membrane; and means for supplying a quantity of massage fluid under pressure to said fluid jet means for emission thereby with sufficient force to transmit a massaging effect through said membrane to the body of a user laying thereon.

Claim 3

Apparatus for body massage according to claim 1 and characterized further by a net affixed to said housing in tensioned condition generally horizontally across said opening beneath said membrane for auxiliary support of a user, said net being of an open mesh construction for generally unrestricted passage therethrough of said massage fluid.

Claim 4

Apparatus for body massage according to claim 1 and characterized further in that said fluid jet means includes means for emitting said massage fluid in rapidly succeeding pulses.

Claim 5

Apparatus for body massage according to claim 1 and characterized further by means for regulating the temperature of said massage fluid.

Claim 6

Apparatus for body massage according to claim 1 and characterized further in that said fluid jet means is movable for traversing travel substantially along said membrane.

Claim 7

Apparatus for body massage according to claim 5 and characterized further by track means for guiding traversing movement of said fluid jet means.

Claim 8

Apparatus for body massage according to claim 5 and characterized further by means for driving traversing movement of said fluid jet means, said driving means comprising a reversible motor and control means for reversing said motor.

Claim 9

Apparatus for body massage according to claim 7 and characterized further in that said control means includes sensing means defining opposite ends of the traversing travel of said fluid jet means.

Claim 10

Apparatus for body massage according to claim 8 and characterized further in that said control means includes a means for selectively determining a lesser extent of traversing travel of said fluid jet means intermediate said sensing means.

Claim 11

Apparatus for body massage according to claim 7 and characterized further in that said driving means comprises a drive screw extending longitudinally through said massage chamber, said drive screw being operatively connected with said reversible motor for driven rotation of said drive screw in opposite directions and said fluid jet means being threaded mounted on said drive screw for driven movement therealong upon rotation thereof.

Claim 12

Apparatus for body massage comprising: a bed structure having a housing defining an interior massage chamber, a liquid reservoir basin beneath said massage chamber, and an upwardly-facing opening communicating with said massage chamber, and a resiliently flexible membrane affixed to said housing in substantially sealing relation generally horizontally across aid opening, said membrane being in sufficiently tension condition for forming a primary weight-bearing body support surface on which a user may lay for massage treatment while retaining sufficient resiliency and flexibility in its tensioned condition to generally conform to a user's body, said reservoir basin containing a quantity of a massage liquid and said massage chamber being substantially filled with air whereby said massage liquid provides essentially no weight bearing support of the user; a massage head movably disposed within said massage chamber for traversing travel substantially along, and in facing relation to, said membrane, said massage head including a plurality of emission openings for directing fluid jet emissions at said membrane; and means for withdrawing said massage liquid from said reservoir basin and supplying said liquid under pressure to said massage head for emission through its said emission openings with sufficient force to transmit a massaging effect through said membrane to the body of a user laying thereon.

Claim 13

Apparatus for body massage comprising: a bed structure having a housing defining an interior massage chamber, a liquid reservoir basin beneath said massage chamber, and an upwardly-facing opening communicating with said massage chamber, and a resiliently flexible membrane affixed to said housing in substantially sealing relation generally horizontally across aid opening, said membrane being in sufficiently tension condition for forming a primary weight-bearing body support surface on which a user may lay for massage treatment while retaining sufficient resiliency and flexibility in its tensioned condition to generally conform to a user's body, said reservoir basin containing a quantity of a massage liquid and said massage chamber being substantially filled with air whereby said massage liquid provides essentially no weight bearing support of the user; a massage head movably disposed within said massage chamber for traversing travel substantially along, and in facing relation to, said membrane, said massage head including a plurality of emission openings for directing fluid jet emissions at said membrane; and means for withdrawing said massage liquid from said reservoir basin and supplying said liquid under pressure to said massage head for emission through its said emission openings with sufficient force to transmit a massaging effect through said membrane to the body of a user laying thereon.

Claim 14

Apparatus for body massage according to claim 11 and characterized further by a net affixed to said housing in tensioned condition generally horizontally across said opening beneath said membrane for auxiliary support of a user, said net being of an open mesh construction for generally unrestricted passage therethrough of said massage liquid.

Claim 15

Apparatus for body massage according to claim 11 and characterized further in that said massage head includes means for emitting said massage liquid in rapidly succeeding pulses.

Claim 16

Apparatus for body massage according to claim 11 and characterized further by means for regulating the temperature of said massage liquid.

Claim 17

Apparatus for body massage according to claim 11 and characterized further by track means for guiding traversing movement of said massage head.

Claim 18

Apparatus for body massage according to claim 11 and characterized further by means for driving traversing movement of said massage head, said driving means comprising a reversible motor and control means for reversing said motor.

Claim 19

Apparatus for body massage according to claim 16 and characterized further in that said control means includes sensing means defining opposite ends of the traversing travel of said massage head.

Claim 20

Apparatus for body massage according to claim 17 and characterized further in that said control means includes a means for selectively determining a lesser extent of traversing travel of said massage head intermediate said sensing means.

Claim 21

Apparatus for body massage according to claim 16 and characterized further in that said driving means comprises a drive screw extending longitudinally through said massage chamber, said drive screw being operatively connected with said reversible motor for driven rotation of said drive screw in opposite directions and said massage head being threadedly mounted on said drive screw for driven movement therealong upon rotation thereof.
