Kinesitherapeutic bed structure

Claim 2

A kinesitherapeutic bed structure comprising in combination: a bed frame; a coil spring assembly carried by said frame and adapted to support a person thereon, said coil spring assembly having an opening therein dimensioned to accommodate the upper vibratory element of a motion generating mechanism therewithin; and a motion generating mechanism carried by said frame and including top and bottom plate elements reciprocable respectively in horizontal vertically spaced planes in mutually perpendicular directions, an upper vibratory element carried by said top plate element for reciprocatory movement therewith, and means for independently imparting horizontal reciprocatory movement to each of said top and bottom plate elements and vertical movement to said upper vibratory element.

Claim 3

A bed structure according to claim 1, including at least two parallel spaced support rails adapted to be mounted on said bed frame, a first set of support shafts carried fixedly by said support rails and extending transversely of said rails, said bottom plate element being mounted on said first set of support shafts for reciprocatory movement therealong, a second set of support shafts carried fixedly by said bottom plate element in overlying relation thereto and extending transversely of said first set of support shafts, and said top plate element being mounted on said second set of support shafts for reciprocatory movement therealong.

Claim 4

A bed structure according to claim 1, wherein rotatable cam means are provided on each of said top and bottom plate elements operatively connected respectively to separate motordriven shafts, a camming surface being provided adjacent each of said cam means, whereby selective rotation of said cam means and engagement thereof with the camming surface adjacent thereto effects reciprocatory movement of the plate element associated therewith, such reciprocatory movement being transmitted by said top plate element to the upper vibratory element carried thereby.

Claim 5

A bed structure according to claim 1, wherein said upper vibratory element comprises a wobble plate, a hollow support cylinder being fixedly mounted on said top plate, a plurality of vertical push rods being mounted within said support cylinder having the upper ends thereof connected pivotably to said wobble plate and the lower ends thereof being provided with roller means, a tilt plate having an upper camming surface rotatably mounted within said support cylinder, spring means being provided for resiliently biasing said wobble plate downwardly and said roller means into engagement with the camming surface of said tilt plate, at least one push rod alignment plate being mounted within said support cylinder having apertures extending therethrough dimensioned to guide said push rods slidably during the vertical movement thereof, and a motor driven shaft operably connected to said tilt plate for rotating same, whereby rotation of said tile plate effectuates vertical reciprocatory movement of said push rods in a predetermined pattern and transmits the desired vertical movement to said wobble plate.

Claim 6

A bed structure according to claim 1, wherein said upper vibratory element comprises a vertical motion plate mounted atop a vertical shaft, a hollow support cylinder enclosing said vertical shaft and being fixedly mounted on said top plate, a vertical slot being formed in a side wall of said support cylinder, a drive rod connected fixedly to said vertical shaft and projecting laterally therefrom and through said slot, said vertical shaft being reciprocable within said support cylinder and said drive rod being adapted to reciprocate within said vertical slot, and a motor driven shaft operably connected to said drive rod for reciprocating same and thereby imparting vertical movement to said vertical motion plate.

Claim 7

A bed structure according to claim 1, wherein said coil spring assembly includes a mattress and box spring and said opening extends through both of said mattress and box spring.
