Abstract
Abstract A therapeutic pad with an armature having a plurality of extended strips in spaced, overlapping relation. Magnetic field means provides an alternating magnetic field in the armature to vibrate the strips by successively inducing and removing magnetic flux into each strip so that adjacent strips successively pull together and relax.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
124 words
A therapeutic pad comprising: field producing means for producing an alternating magnetic field; and a metal armature assembly adjacent to said field producing means for providing vibrations when said field producing means produces an alternating magnetic field, said armature comprising a plurality of elongated metal strips having their lengths disposed substantially normal to the direction of said magnetic field and parallel to each other at least a portion of adjacent ones of said strips overlapping and overlaying each other in the direction lateral to their direction of length, and being spaced apart from one another said magnetic field tending to move an edge of each strip toward an edge of its adjacent strip, whereby to impart a rotary, twisting motion to the said strips.
Claim 2
Dependent Claim
124 words
A therapeutic pad comprising: field producing means for producing an alternating magnetic field; and a metal armature assembly adjacent to said field producing means for providing vibrations when said field producing means produces an alternating magnetic field, said armature comprising a plurality of elongated metal strips having their lengths disposed substantially normal to the direction of said magnetic field and parallel to each other at least a portion of adjacent ones of said strips overlapping and overlaying each other in the direction lateral to their direction of length, and being spaced apart from one another said magnetic field tending to move an edge of each strip toward an edge of its adjacent strip, whereby to impart a rotary, twisting motion to the said strips.
Claim 3
Dependent Claim
33 words
Apparatus according to claim 1 wherein said field producing means comprises conductive coil means wrapped around said armature assembly, with its windings extending generally parallel to the direction of length of the strips.
Claim 4
Dependent Claim
28 words
Apparatus according to claim 2 wherein spacer means is bonded to an end of each of said strips to maintain each strip in said overlapping and spaced relation.
Claim 5
Dependent Claim
16 words
Apparatus according to claim 2 further including half-wave rectifier means in series with said coil means.
Claim 6
Dependent Claim
58 words
Apparatus according to claim 1 wherein said elongated strips are warped when in their relaxed position, the strips being so arranged and disposed that a portion of each strip contacts a portion of the edge of its next adjacent strip and a portion of each strip is thereby held spaced from a portion of the next adjacent strip.
Claim 7
Dependent Claim
30 words
Apparatus according to claim 1 wherein the strips are substantially flat and rectangular, and in which resilient frame means is provided which holds the end of each of said strips.
Claim 8
Dependent Claim
28 words
Apparatus according to claim 6 wherein spacer means is bonded to an end of each of said strips to maintain each strip in said overlapping and spaced relation.
Claim 9
Dependent Claim
118 words
Apparatus according to claim 2 wherein said coil means comprises a plurality of conductive coils, half-wave rectifier means in series with said plurality of conductive coils, and normally closed thermostat means short circuiting said rectifier means and at least one of said coils, said thermostat means opening in response to heat produced by another of said plurality of coils, whereby when alternating current is initially supplied to said coil means, full power is supplied to said oTher of said plurality of coils through said thermostat means to heat said other coil and said thermostat means opens in response to heat produced by said other coil so that said half-wave rectifier means reduces power to said plurality of coils.
Claim 10
Dependent Claim
58 words
Apparatus according to claim 2 wherein said elongated strips are warped when in their relaxed position, the strips being so arranged and disposed that a portion of each strip contacts a portion of the edge of its next adjacent strip and a portion of each strip is thereby held spaced from a portion of the next adjacent strip.
Claim 11
Dependent Claim
30 words
Apparatus according to claim 2 wherein the strips are substantially flat and rectangular, and in which resilient frame means is provided which holds the end of each of said strips.
Claim 12
Dependent Claim
47 words
Apparatus according to claim 2 wherein said coil means comprises a multi-filar coil, and in which a stepdown transformer has its primary winding adapted for connection to a source of alternating current and has its secondary winding connected to the ends of each filar of said coil.
