Abstract: A chiropractic table has a power-operated linkage that will simultaneously tilt the table as it is lowered from an elevated position and also return the table to a horizontal position as it is elevated. The table employs a modified, movable parallelogram type of linkage, as opposed to a scissors-type linkage, which when combined with an open center frame allows the table to be lowered to a height not attainable with the prior art tables. A patient footplate assembly includes additional linkage and is operated by the tilt actuator so that when the table is elevated, the footplate is rotated out of the way, and when the table is tilted and lowered, the footplate will be rotated upwardly into position so that the patient can easily step off the table.

Abstract: A mounting for the head section of a chiropractic table that allows the practitioner to maintain a much greater degree of control over the various manipulations typically performed on the patient. The head support section has a cushion that is mounted for slideable movement along the longitudinal axis of the table which coincides with the patient's spine. A linkage arrangement allows the proximal end of the cushion to remain substantially the same distance from the chest lumbar section of the table as the head section is tilted downwardly. This allow a controlled flexion movement of the patient's cervical spine. The amount of gap and thus the amount of flexion can be adjusted by adjusting the linkage that is a part of the head section structure. In addition, the slideable movement of the head cushion longitudinally allows the practitioner to apply traction to the patient's spine with or without flexion, if such a movement is determined to be desirable.

Abstract: A mechanism for controlling the raising and lowering of the foot plate on a chiropractic table of the tilt-elevating type. The foot plate is pivotly mounted on the fixed base and has stabilizer pins that are engaged by lugs on the upper or moveable part of the table when the table is tilted and disengaged when the table is returned to a horizontal position. A sliding bar and roller mechanism slowly lowers the foot stand to its normal position on or near the floor.
