Abstract
Abstract A vibratory transducer in combination with a water bed structure including a frame with vertical side walls, a horizontal platform within the frame and a water filled bladder mattress within the frame and supported by the platform; said transducer includes a body in seated engagement in a corner established by the top of the platform on the inner surface of one side wall, said body has an inwardly and upwardly disposed inner side with an access opening extending diagonally across said corner; a drive plate is engaged with the mattress and overlies said inner side in spaced relationship, means is provided to couple the plate with the body for limited movement relative thereto; an electro magnetic vibrator is fixed to the plate to project freely through said access opening and into the body and is operable to vibrate the plate and transmit vibratory motion into and through the mattress.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
140 words
In combination, a water bed structure including a frame with at least one vertical side wall, a horizontal platform within the frame and a water filled bladder mattress contained within the frame adjacent said side wall and supported on the platform, a transducer unit including an elongate body arranged in a portion of the corner defined by the platform and said wall and having an outer side engaged with said wall, a bottom side engaged with said platform and an upwardly and inwardly disposed inner side opposing the mattress, a plate positioned between the mattress and the inner side of the body and supporting the portion of the mattress adjacent the unit, resilient coupling means coupling the plate with the body for limited relative movement therebetween and an electro-magnetic vibrator fixed to said plate and projecting freely into the body.
Claim 2
Dependent Claim
140 words
In combination, a water bed structure including a frame with at least one vertical side wall, a horizontal platform within the frame and a water filled bladder mattress contained within the frame adjacent said side wall and supported on the platform, a transducer unit including an elongate body arranged in a portion of the corner defined by the platform and said wall and having an outer side engaged with said wall, a bottom side engaged with said platform and an upwardly and inwardly disposed inner side opposing the mattress, a plate positioned between the mattress and the inner side of the body and supporting the portion of the mattress adjacent the unit, resilient coupling means coupling the plate with the body for limited relative movement therebetween and an electro-magnetic vibrator fixed to said plate and projecting freely into the body.
Claim 3
Dependent Claim
36 words
The structure set forth in claim 1 wherein the plate has longitudinally outwardly extending and longitudinally outwardly divergent fairing at its opposite ends projecting freely into portions of the corner at opposite ends of the body.
Claim 4
Dependent Claim
36 words
The structure set forth in claim 1 wherein the body has longitudinally outwardly convergent fairing extending longitudinally from its opposite ends and terminating in the portions of the corner remote from the ends of the body.
Claim 5
Dependent Claim
37 words
The structure set forth in claim 1 wherein the coupling means includes resilient means engaged with and between a plate and the body resiliently supporting the plate in spaced relationship from the body for free relative movement.
Claim 6
Dependent Claim
36 words
The structure set forth in claim 4 wherein the plate has longitudinally outwardly extending and longitudinally outwardly divergent fairing at its opposite ends projecting freely into portions of the corner at opposite ends of the body.
Claim 7
Dependent Claim
36 words
The structure set forth in claim 4 wherein the body has longitudinally outwardly convergent fairing extending longitudinally from its opposite ends and terminating in the portions of the corner remote from the ends of the body.
