Abstract
Abstract A substantially planar platform having a mattress supported thereon is pivotally attached toward one end to a framework. A bed support structure has a pair of arcuate surfaces which engage the lower face of the platform. The arcuate surfaces are attached to a pair of channel bars which are supported on wedge-shaped elements. The channel bars are pivoted on a common axis and the wedge-shaped elements are moved forwardly by a screw and follower mechanism thereby pivoting the channel bars to move the arcuate supports upwardly against the bottom of the platform. This pivots the platform upwardly. The pivot axis of the channel comprises a tube mounted on an eccentric shaft. The eccentric shaft is rotated under power thereby causing vibration of the entire mechanism resulting in oscillatory motion to relieve stress, strain and tension in the user and aid in the treatment of back and circulatory ailments.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
138 words
In a therapeutic bed, the combination of: a bed support frame having ground engaging legs; a platform for supporting a user of the bed; said platform having a pivot joint connected toward one end thereof, said pivot joint also being connected to said bed support frame for allowing said platform to pivot about a horizontal axis to a plurality of inclined positions; a lifting mechanism engaged with said platform and including lifting means for raising said platform to one of said inclined positions; an eccentric shaft mounting said lifting mechanism, said lifting mechanism including at least one arcuate support slidably engaging the bottom of said platform and connected for rotative movement about said eccentric shaft for raising said platform; and power means for rotating said eccentric shaft to cause vibratory motion of said lifting mechanism and said platform.
Claim 2
Dependent Claim
138 words
In a therapeutic bed, the combination of: a bed support frame having ground engaging legs; a platform for supporting a user of the bed; said platform having a pivot joint connected toward one end thereof, said pivot joint also being connected to said bed support frame for allowing said platform to pivot about a horizontal axis to a plurality of inclined positions; a lifting mechanism engaged with said platform and including lifting means for raising said platform to one of said inclined positions; an eccentric shaft mounting said lifting mechanism, said lifting mechanism including at least one arcuate support slidably engaging the bottom of said platform and connected for rotative movement about said eccentric shaft for raising said platform; and power means for rotating said eccentric shaft to cause vibratory motion of said lifting mechanism and said platform.
Claim 3
Dependent Claim
39 words
The therapeutic bed defined in claim 1 and further wherein said lifting mechanism includes a downwardly facing channel member having said arcuate support connected to the top thereof and having one end connected for pivotal movement about said shaft.
Claim 4
Dependent Claim
48 words
The therapeutic bed defined in claim 2 and further wherein said lifting mechanism includes a rotatable screw, a follower means mounted on said screw for longitudinal movement therealong upon rotation of said screw and a block mounted to said follower means and slidably disposed beneath the channel member.
Claim 5
Dependent Claim
27 words
The therapeutic bed defined in claim 2 and further wherein said lifting mechanism includes a second power means connected to said screw for causing powered rotation thereof.
Claim 6
Dependent Claim
163 words
In a therapeutic bed, the combination of: a bed support frame having ground engaging legs; a platform for supporting a user of the bed, said platform having a pivot joint connected toward one end thereof, said pivot joint also being connected to said bed support frame for allowing said platform to pivot about a horizontal axis to a plurality of inclined positions; an eccentric shaft mounting said lifting mechanism, said lifting mechanism including a tube mounted on said eccentric shaft with said tube supporting said platform when said platform is in an inclined position, said lifting mechanism further including an elongated guide member attached to and extending radially away from said tube, and a raising block means slidably disposed on said guide member, and movement means for moving said block means relative to said guide member thereby pivoting said guide member and said tube; and power means for rotating said eccentric shaft to cause vibratory motion of said lifting mechanism and said platform.
Claim 7
Dependent Claim
163 words
In a therapeutic bed, the combination of: a bed support frame having ground engaging legs; a platform for supporting a user of the bed, said platform having a pivot joint connected toward one end thereof, said pivot joint also being connected to said bed support frame for allowing said platform to pivot about a horizontal axis to a plurality of inclined positions; an eccentric shaft mounting said lifting mechanism, said lifting mechanism including a tube mounted on said eccentric shaft with said tube supporting said platform when said platform is in an inclined position, said lifting mechanism further including an elongated guide member attached to and extending radially away from said tube, and a raising block means slidably disposed on said guide member, and movement means for moving said block means relative to said guide member thereby pivoting said guide member and said tube; and power means for rotating said eccentric shaft to cause vibratory motion of said lifting mechanism and said platform.
