Abstract

The chiropractic table of the present invention includes a base frame, an intermediate frame above the base frame, and a table frame above the intermediate frame. A plurality of independently movable support pieces are mounted to the table frame and extend above the table frame to provide a support surface for the patient. The table may be tilted about a horizontal axis from a horizontal position to a near vertical position. It may also be elevated or lowered when in its horizontal position. One or more of the support pieces include a cock and drop feature which permits the chiropractor to elevate the piece to a predetermined height. The chiropractor then places downward pressure on the patient at a point directly above the support piece which has been elevated. A system of cams and cam followers hold the elevated piece in its upper position until the pressure reaches a predetermined magnitude, at which time the support piece is released and drops to its original position. The thoracic support piece is tilted about a horizontal axis at its middle, and includes a cock and drop feature at each of its opposite ends. The table also includes an arm rest which is movable beyond one end of the table to provide a knee rest when desired. The table also includes a continually adjustable face or heat piece.

Claims

1. A body support assembly for a chiropractic table having

a frame comprising:

a support box having opposite ends;

mounting means for pivotally mounting said support box to said frame for pivotal movement about a horizontal axis;

lock means for selectively locking said support box in any of a plurality of pivotal positions about said horizontal axis;

a support piece positioned above said support box and having opposite ends;

a first and second cock and drop assemblies, each supporting said support piece at one of said opposite ends,

said first and second cock and drop assemblies each being movably mounted to said support box for movement from a cocked position supporting one of said opposite ends of said support piece in an elevated position to a drop position supporting said one opposite end in a lower position;

power means for selectively and independently raising said cock and drop assemblies to their cocked positions, said power means being deactuatable to permit said cock and drop assemblies to fall by gravity to their drop positions,

connecting means movably connecting said support piece to said support box whereby said opposite ends are free to move vertically with said first and second cock and drop assemblies.

2. A chiropractic table comprising:

an elongated table frame,

a plurality of support pieces positioned in spaced relation along the length of said table frame and each having an upwardly presented support surface,

mounting means for mounting at least one of said support pieces to said frame for vertical movement between upper and lower positions;

a vertically movable member in supporting engagement with said one support piece and being vertically movable with said one support piece between said upper and lower positions;

a cam connected to said one support piece for vertical movement therewith, said cam having a cam surface comprising a curved surface having a recessed portion therein,

a cam follower in rolling engagement with said cam surface and adapted to roll into said recessed portion when said vertically movable member and said one support piece are in said upper position;

yieldable power means connected to said cam follower for urging said cam follower into said recessed portions with a force of predetermined magnitude and being yieldable to permit said cam follower to roll out of said recessed portion in response to a downward force of predetermined magnitude exerted on said one support piece and said vertically movable member.
